For example, a plastic film folding machine with publication number CN116619775B comprises: a film guiding base, a folding guiding assembly, a folding forming assembly, and a unwinding roller, a tension guide frame and a guide rod located on the surface of the film guiding base. The folding guiding assembly and the folding forming assembly are fixedly mounted on the surface of the film guiding base and are located on the same straight line as the unwinding roller, the tension guide frame and the guide rod. The folding guiding assembly comprises a first guide frame, a second guide frame and a plurality of guide strips. The first guide frame and the second guide frame are arranged in parallel and have cross guide rods and adjustment trusses on their surfaces, respectively. By setting up a secondary folding structure, the edge of the film is driven by the film unwinding and winding to pass through the folding guide assembly and the folding roller in turn, and the edge of the film surface is bent and folded twice. Subsequently, the active roller is rolled and the shaping roller group is welded and bonded to form the film folding in one step, avoiding adverse effects such as folding line deviation and folding width fluctuation. However, the plastic film folding machine still has the following disadvantages in actual use:

[0003] The guiding mechanism on traditional folding machines mostly guides the workpiece by pulling. After the guided workpiece is processed, it is not convenient to continuously guide and transport the subsequent workpieces. In addition, the stability during the transportation process is poor, which can easily cause the position of the workpiece to shift, thereby affecting the accuracy of the processing. In view of the above problems, it is urgently necessary to carry out innovative design based on the original guiding structure. Utility Model Content

[0004] The purpose of the utility model is to provide a guiding structure for a folding machine to solve the problem proposed in the above background technology that the guiding mechanisms on traditional folding machines mostly guide the workpiece by pulling. After the guided workpiece is processed, it is not convenient to continuously guide and transport the subsequent workpieces, and the stability is poor during the transportation process, which can easily cause the position of the workpiece to shift, thereby affecting the accuracy of the processing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guiding structure of a folding machine, provided with a processing table, a support frame is fixed to the upper end surface of the processing table, and a servo motor is installed on the side of the support frame, the output shaft of the servo motor is connected to a screw rod, and a movable cylinder is sleeved on the outer side of the screw rod, and a guiding mechanism is connected to the bottom of the movable cylinder, and the guiding mechanism is used to guide the movement of the copper sheet;

[0006] It comprises: a fan blade, which is fixedly mounted on one end of the screw rod away from the servo motor; a protective box is sleeved on the outer side of the fan blade, and the protective box is fixed on the supporting frame.

[0007] Preferably, one of the movable cylinders and the screw rod is threadedly connected, and the other movable cylinder and the fixed rod are slidingly connected, and the movable cylinder is symmetrically distributed about the vertical axis of the processing table, and the fixed rod is fixed to the inner side of the support frame. When the screw rod rotates, it can drive the movable cylinder to move horizontally through threaded transmission with the movable cylinder.

[0008] Preferably, the guiding mechanism comprises a movable tube penetrating the bottom of the movable cylinder, and the movable tube and the movable cylinder are slidably connected, and the movable tube can adjust the distance between the movable tube and the copper sheet by rising and falling in the movable cylinder.

[0009] Preferably, a suction cup is connected to the bottom of the movable tube, and the movable tube is connected to the suction cup through the movable tube, and the copper sheet can be adsorbed by the suction cup so that the copper sheet can be subsequently transported forward.

[0010] Preferably, a connecting pipe is fixed between the two movable tubes, and the two movable tubes are connected through the connecting pipe, and gas communication is achieved between the movable tubes through the connecting pipe, so that the two suction cups can adsorb the copper sheet at the same time.

[0011] Preferably, the protection box is connected to the movable cylinder through an air pipe, a connecting rod is fixed to the side of the movable tube away from the connecting tube, and the suction force generated by the rotation of the fan blades can be transmitted to the movable cylinder through the air pipe.

[0012] Preferably, the connecting rod forms a sliding structure through a guide groove and a support frame, and the guide groove of the support frame is opened on the side of the support frame, and the heights of both ends of the guide groove are higher than the height of the middle position thereof, and when the movable cylinder moves, it drives the connecting rod to slide in the guide groove.

The specific contents are as follows:

[0014] 1. The threaded transmission between the lead screw and the movable tube can drive it to move horizontally. During the movement, the connecting rod is driven to slide in the guide groove. On the one hand, the stability of the movable tube during movement is ensured, and on the other hand, the height of the movable tube can be adjusted during movement.

[0015] 2. The suction force generated by the rotation of the fan blades can be transmitted to the movable cylinder through the air pipe, and then transmitted to the suction cup through the movable pipe, and finally the copper sheet can be adsorbed on the suction cup. When the fan blades stop rotating and no longer provide suction, the suction cup releases the adsorption of the copper sheet, so that the copper sheet that has been transported falls down for folding processing;

[0016] Furthermore, when the servo motor is driven in reverse, the wind force generated by the rotation of the fan blades can be transmitted to the movable cylinder through the air pipe. In this way, when the suction cup moves to the left, the gas can be discharged and blown onto the copper sheet to clean the copper sheet, thereby ensuring stability during subsequent adsorption.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0026] In order to solve the problems existing in the prior art, the present embodiment adopts the following technical scheme: a guiding structure of a folding machine, which is provided with a processing table 1, a support frame 2 is fixed on the upper end surface of the processing table 1, and a servo motor 3 is installed on the side of the support frame 2, the output shaft of the servo motor 3 is connected to a screw rod 4, and a movable cylinder 5 is sleeved on the outer side of the screw rod 4, and a guiding mechanism is connected to the bottom of the movable cylinder 5, and the guiding mechanism is used to guide the movement of the copper sheet; including: a fan blade 10, which is fixedly installed on the end of the screw rod 4 away from the servo motor 3, and a protective box 11 is sleeved on the outer side of the fan blade 10, and the protective box 11 is fixed on the support frame 2.

[0027] Most of the guiding mechanisms on the existing folding machines guide the workpiece by pulling. After the guided workpiece is processed, it is not convenient to continuously guide and transport the subsequent workpiece, and the stability during transportation is poor, which can easily cause the position of the workpiece to shift, thereby affecting the accuracy of processing. One of the movable cylinders 5 and the screw rod 4 is threadedly connected, and the other movable cylinder 5 and the fixed rod 9 are slidably connected, and the movable cylinder 5 is symmetrically distributed about the vertical axis of the processing table 1, and the fixed rod 9 is fixed to the inner side of the support frame 2; the guiding mechanism includes a movable tube 6 that passes through the bottom of the movable cylinder 5, and the movable tube 6 and the movable cylinder 5 are slidably connected; the bottom of the movable tube 6 is connected to a suction cup 7, and the movable cylinder 5 is connected by The movable tube 6 and the suction cup 7 are interconnected; a connecting tube 8 is fixed between the two movable tubes 6, and the two movable tubes 6 are connected through the connecting tube 8; the protective box 11 is interconnected with the movable cylinder 5 through the air supply pipe 12, and a connecting rod 13 is fixed on the side of the movable tube 6 away from the connecting tube 8; the connecting rod 13 forms a sliding structure with the support frame 2 through the guide groove 14, and the guide groove 14 of the support frame 2 is opened on the side of the support frame 2, and the heights of the two ends of the guide groove 14 are higher than the height of the middle position; the copper sheet to be guided and transported is placed on the processing table 1, and then when the servo motor 3 drives the screw rod 4 to rotate, the movable cylinder 5 can be driven to move horizontally through the threaded transmission of the screw rod 4 and the movable cylinder 5, and the movable tube 6 is driven during the movement. It moves synchronously with the connecting rod 13. The connecting rod 13 can slide in the guide groove 14 when it moves. On the one hand, it ensures the stability of the movable tube 5 when it moves, and on the other hand, it can adjust the height of the movable tube 6 when it moves. When the movable tube 5 moves to the right, the sliding of the connecting rod 13 in the guide groove 14 can drive the movable tube 6 to descend and approach the copper sheet. Then, the rotation of the screw rod 4 can drive the fan blades 10 to rotate synchronously. Since the thread grooves on the outside of the screw rod 4 are relatively dense, the screw rod 4 can drive the fan blades 10 to rotate and generate suction when it rotates at a high speed, and at the same time, it can drive the movable tube 5 to move at a low speed. The suction generated by the rotation of the fan blades 10 can be transmitted to the movable tube 5 through the air supply pipe 12, and then transmitted to the suction cup through the movable tube 6. 7, the copper sheet can be finally adsorbed on the suction cup 7. Since the suction cup 7 is symmetrically distributed, the other movable cylinder 5 slides on the fixed rod 9, and the suction cup 7 is adsorbed on the two edges of the copper sheet, so that the subsequent suction cup 7 can ensure stable transportation of the copper sheet when moving. When the maximum distance is transported, the servo motor 3 stops driving, the fan blade 10 stops rotating and no longer provides suction, and the suction cup 7 releases the adsorption of the copper sheet. In this way, the copper sheet that has been transported falls down for folding processing, and when the servo motor 3 is driven in the reverse direction, the wind force generated by the rotation of the fan blade 10 can be transmitted to the movable cylinder 5 through the air pipe 12. In this way, when the suction cup 7 moves to the left, the gas can be discharged and blown onto the copper sheet to clean the copper sheet, thereby ensuring stability during subsequent adsorption.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
