[0025] like Figure 1-Figure 5 As shown, specifically, a threaded hole is processed on the bottom end panel of the partition frame 1, and the lead screw of the anchor 2 is screwed into the threaded hole on the bottom end panel of the partition frame, and the height of the equipment is adjusted by how much the anchor thread is screwed in.

[0026] Threaded holes are processed on the upper plane of the partition frame, countersunk holes are processed on the partition bottom plate 3, and screws are used to fix the partition bottom plate on the upper plane of the partition frame.

[0027] The partition front plate 4, the partition back plate 17, the two partition side plates 5 and the partition bottom plate are assembled into a box body, the partition front plate, the partition back plate, the partition side plates have threaded holes on their bottom end faces, and the corresponding countersunk holes are processed at the positions of the partition bottom plate. The screws are passed from bottom to top to fix the assembled box body on the partition bottom plate, forming a paper partition material box with an upper opening.

[0028] The gear box bottom plate 7 is fixed to the front plate of the partition, and threaded holes are processed on both end faces of the gear box mounting plate, and countersunk holes are processed at the corresponding positions of the gear box bottom plate. The screws are inserted from the inside to the outside to fix the gear box mounting plate 12 to the gear box bottom plate 7. The countersunk holes processed on the gear box upper plate 11 correspond to the threaded holes on the other side of the end face of the gear box mounting plate, and the gear box upper plate is fixed to the gear box mounting plate 12 with screws.

[0029] The cylindrical gear 8 and the bridge pulley 9 are inserted on the toothed belt shaft 10, and the shaft necks at both ends of the toothed belt shaft are respectively inserted into the bearing holes of the upper plate 11 of the gear box and the bottom plate of the gear box. The two bearing seat mounting plates 14 are fixed to the outer side of the partition side plate with screws, and the two bearing seats 16 are respectively fixed to the two bearing seat mounting plates. The winding shaft 13 passes through the two bearing seats. The bearing seats themselves have top screws. After adjusting the position of the winding shaft, the top screws can be tightened to prevent axial stringing. Two synchronous pulleys 15 are installed at the corresponding positions in the middle of the winding shaft. The synchronous pulleys also have top screws. After adjusting, tighten the top screws to fix the synchronous pulleys. In addition, there is another synchronous pulley 15 installed at the end of the winding shaft. After adjusting the position, tighten the top screw to fix it. The intermediate belt 26 is installed on the synchronous pulley 15 and the bridge pulley 9 at the end of the winding shaft.

[0030] The sling 18 passes around the synchronous pulley, and the sling mounting plate 19 and the sling pressing plate 20 are screwed and pressed on one end of the sling, and the other end of the sling is screwed and pressed with a sling pressing plate and a spring hook 29. One end of the tension spring 33 is hung on the spring hook, and the other end is hung on the hook on the partition frame.

[0031] The partition support plate 6 is processed with threaded holes, and the horizontal bending edge of the sling mounting plate is processed with through holes, and the partition support plate is fixed to the sling mounting plate with screws.

[0032] The two ends of the limit rod 32 are cut with notches, and the two notches are clamped on the two edges in the middle of the partition side plate. A through hole is opened at one end of the notch side and a threaded hole is opened at the other end. Screws are screwed in to clamp the notch. The upper and lower heights of the limit rod are adjusted to adjust the amount of paper partition loaded.

[0033] like Figure 6 As shown, the material stopper assembly mounting plate 25 is installed on the partition front plate 4 and the partition rear plate 17 and fixed with screws. The bottom of the material stopper pin sleeve 21 is processed with a threaded hole, and the horizontal plane of the material stopper mechanism mounting plate 25 is processed with a long waist hole. The material stopper pin sleeve is fixed on the horizontal plane of the material stopper mechanism mounting plate through screws. The stopper pin plugging plate 24 is installed at the rear end of the material stopper pin sleeve and fixed with screws. The compression spring 23 is placed in the material stopper pin sleeve, and then the material stopper pin 22 is inserted into the material stopper pin sleeve. A threaded hole perpendicular to the center line is processed at the outer circle busbar of the material stopper pin. The screw passes through the long waist hole on the upper part of the material stopper pin sleeve and is screwed into the threaded hole at the outer circle busbar of the material stopper pin. The screw is not tightened here, but only serves as a guide. The screw can move back and forth in the long waist hole on the upper part of the material stopper pin sleeve.

[0034] The partition switch bracket 28 is installed at the center notch of the upper edge of the partition front plate and the partition rear plate and fixed with screws. The photoelectric switch 27 is installed on the horizontal flange of the partition switch bracket. The function of the photoelectric switch is to send a signal to the control system when the cardboard partition is used up. The system reminds the operator to add paper partitions through sound and light alarms.

[0035] Both ends of the protective mounting column 31 are processed with threaded holes, and the front plate and the rear plate of the partition are processed with countersunk holes. The protective mounting columns are fixed to the front plate and the rear plate of the partition respectively by screws from the inside to the outside. Through holes are processed at the corresponding positions of the protective cover 30, and the protective cover is installed on the protective mounting columns by screws.

[0036] A tension spring guard 34 is also provided at the tension spring position, and the tension spring guard is mounted on the partition side plate by screws.

[0037] Workflow:

[0038] Placing paper partitions: The operator places a certain number of stacked paper partitions on the partition support plate and presses down hard from top to bottom. Since the head of the stop pin is an inclined surface, there will be a lateral force to retract the stop pin. When the uppermost paper partition is pressed into the lower part of the stop pin, the stop pin is no longer subjected to the lateral force and pops out relying on the elastic force of the compression spring. Under the tension of the tension spring, the paper partition is fixed between the partition support plate and the stop pin.

[0039] Taking out paper partition: The gripper is close to the uppermost paper partition surface, and the stop pin is retracted by the lateral force. The gripper takes out the cardboard and the compression spring pushes the stop pin out at the same time. The lower paper partition is pressed against the lower plane of the stop pin by the tension of the tension spring.

[0040] The synchronous pulley, bridge pulley, cylindrical gear and sling cooperate to realize the horizontal movement of the partition tray. When the operator puts the paper partition into the machine, the partition tray will be uneven due to uneven palm force or uneven friction, which will cause the equipment to be unstable and the entire paper partition stack will be stuck in the machine. To eliminate this phenomenon, it is necessary to ensure that the partition tray is horizontal when it falls or rises. The synchronous mechanism can ensure that the synchronous mechanism partition tray is horizontal when it is raised or lowered. The principle is that when the partition tray is raised or lowered, it will drive the sling to rise and fall. The sling and the synchronous pulley are meshed, so the synchronous pulley rotates, and the synchronous pulley drives the winding shaft to rotate, which is transmitted to the cylindrical gear. The cylindrical gears on both sides mesh with each other and rotate synchronously, so that the synchronous mechanism on the opposite side will also rotate at the same speed, thereby eliminating the unevenness of the partition tray caused by uneven force.

[0041] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements of the present invention by relevant technical personnel in the field should be extended to the protection scope determined by the claims of the present invention.
