Disadvantage Advantage
1. Using ordinary rails; 1. Left and right baffle with a linear guide, high-precision displacement
2. Left and right baffle manual adjustment; 2. Left and right baffle motorized adjustment;
3. There is no positioning knife in the rear stop. 3. With an independent remote control adjustment platform and positioning knife, positioning accuracy;
4. Using ordinary suction fan; 4. Using Taiwan or through Hong Pu Pu-HTB multi-stage high-pressure fan, paper feeding stability, high efficiency and stability;
5. Rear fixed pallets can not be adjustable; 5. Rear pallet up and down according to the size of the cardboard can be adjusted in order to stabilize the delivery;
6. The feeding belt can not be adjusted individually 6. Can be individually adjusted elastic, to avoid distortion caused by the belt elastic.

3. Creasing Section:
Adopts 3 sets of creasing wheel fixed at the wall fame (The first supplier R&D in China).

Other supplier's creasing design We first R&D Designing in China
Disadvantage Advantage
a. Changing the creasing wheels is inconvenient, have to disassemble all bearings and shafts a. Convenient to change, can disassemble individually, good for maintenance and changing the creasing wheels, save the time.
b. Creasing precision can not be ensured, as is depending on the shafts which are slender and thin, it will jump when the cardboard transferred, can not ensure the creasing wheels rotating precision. It doesn’t achieve the expect effect, but damage the board to be cracking. b. The creasing wheels are fixed at the wall frame, the precision is ensured by the high load bearings, the rotating precision can controlled within ±0.1mm, The supporting guide rod for the wall frame the compressive strength can reach more than 250Tons, therefore the creasing can be very stable and smooth, and achieve the creasing effect.
c. The left and right side creasing precision is controlled by the shifting fork when move for the positioning, as there has the gap between block and creasing wheels, it will swing left and right when working, easy to cause the creasing errors. c. The creasing wheels left and right side positioning is controlled by the precise lead screws,  it’s positioning perfect at the high speed running, can achieve the forming precision requirement.
d. The mentioned structure here only 2 sets of creasing wheel d. And here structure is 3 sets creasing wheels from light to deep, ensure the precision.

4. Folding Unit:
(1) According to different shapes of cartons boxes, the front end of the folding unit is provided with a glue device. The glue device is composed of a lower rubberizing wheel, an upper pressing roller and a plastic box.
(2) Cardboard is mainly through two 120mm wide bottom belt and two 80mm wide bending belt and two folding catheter to achieve the left and right sides of the second fold line and the fourth fold line of 180 degrees of the fold forming.
(3) There are many different angles of the guide wheel, according to the different paper and cardboard thickness, adjust the guide wheel of different positions and angles, so that more smoothly folded cardboard.
(4) A plurality of supporting bearings are arranged below the belt so as to support the guiding belt to run smoothly.
(5) The down belt is equipped with positioning on both sides of the track to ensure that high-speed belt does not fall off.
(6) Plastic box with high-quality precision aluminum, never rust, the bottom with a drainage hole.
(7) The up belt is equipped with automatic lifting device, troubleshooting easy and quick.
(8) There are independent vacuum suction fans on the left and right belts of the lower belt to ensure the stability of the carton forming and avoid the traffic jams caused by different spacing. The upper and lower belt gaps can be adjusted automatically.
(9) The size of the seam control: left and right on the board with a set of 3-meter-long medial guide wheel positioning system, the next round drive molding to ensure that the carton forming accuracy and the beauty of both sides.

(10) Left and right under the guide plate combined welding into L-type, cold and heat treatment after processing, strong and stable.
(11) Track the use of precision linear guide, high precision, durable.

Disadvantage Advantage
When the paperboard is folded, it is adjusted by the gap between the folding knife and the lower belt. Because different paperboard gap is not the same, the debugging is difficult. When the gap and the thickness of the paperboard are not the same, the paper feeding method belongs to Out of control, is free to swing, so high-speed operation is likely to cause traffic jam, resulting in decreased production and increased scrap. When the cardboard enters, it will be sucked by the vacuum on the lower belt, so as to ensure that the cardboard is tightly adsorbed on the lower belt. The high speed is very stable and the carton forming precision is high.

5. Pull Regulating Unit:
(1) Using four imported non-slip tape, to ensure that high-speed operation of cardboard boxes to ensure stability.
(2) About two pairs of belts can be individually adjusted according to the side of the carton size.
(3) Pressure using high-quality spring steel, the gap is adjusted separately;
(4) The belt can be replaced without dismantling the shaft;
(5) The up belt drive with CVT, inverted carton box appears, the adjustable speed with fast, improve the speaker.

6. Correction section unit:
(1) The belt can be adjusted according to the length of the carton to ensure that the belt does not beat when the beat, beat no resistance.
(2) Beat the Department of the use of servo motor, speed fast, accurate.
(3) left and right wheels use of chrome-plated metal wheels, long life.
(4) Take the robot position after the shoot, no scissors.
(5) Upper and lower belt gap can be automatically adjusted.
(6) The system will automatically shut down to avoid waste into a piece of cardboard boxes to reduce downtime.

7. Stitching Unit
(1) Nail head can be put 1100 nails per minute;
(2) Nail head with swing structure, to prevent the fast hole under the nail will be widened;
