An automatic feeding structure for a PVC hose shearing machine

Abstract

This utility model relates to the field of PVC hose technology, specifically to an automatic feeding structure for a PVC hose shearing machine. It includes a mounting plate with a moving groove at its upper end. When the hose needs to be transferred, a clamping mechanism moves the clamping ring and the hose. When the hose reaches the far right, the shearing device cuts the hose, simultaneously releasing the clamping mechanism from the hose. Then, the abutment rod rotates and abuts against the force plate again, resetting the force plate and clamping ring. Similarly, the clamping mechanism returns to its initial position and clamps the hose again via a pressure block and another abutment rod, facilitating the repositioning of the hose to the shearing position. This design allows the hose to be continuously and intermittently pulled to the right, improving the hose shearing efficiency. Furthermore, the mechanical mechanism replaces programmed control, simplifying the operation steps and facilitating subsequent maintenance and repair.

Description

Technical Field

[0001] This utility model relates to the field of PVC hose technology, specifically to an automatic feeding structure for a PVC hose shearing machine. Background Technology

[0002] PVC pipes are made by hot-pressing polyvinyl chloride resin with stabilizers, lubricants, etc., and are the earliest plastic pipes developed and applied. A shearing machine is a type of machine tool that is hydraulically driven, has reliable safety performance, and is easy to operate.

[0003] A search of publication number "CN217833830U" reveals "A shearing machine for producing PVC antistatic plastic hoses, comprising a machine base, a feeding device and a cutting device on the machine base, a cylinder on the top of the machine base, and a sliding rod that moves along its axial direction inside the cylinder. In this invention, a protrusion is provided on the sliding rod, a movable rod is provided on the side wall of the cylinder, a roller is provided on the movable rod, and an electric push rod is provided on the end face of the cylinder. The advantages of this design are: the hose is pushed by the feeding device, and during transmission, the inner wall of the hose is in contact with the roller. The roller on the outer side of the cylinder supports and transmits the hose, thus keeping the hose in a straight line and preventing bending and deviation; secondly, by adjusting the extension and retraction of the electric push rod, the protrusion lifts the movable rod, thereby allowing the movable rod and roller to match the diameter of the hose, making the shearing machine suitable for hoses of various diameters and improving the practicality of the equipment." The aforementioned patent allows the transmission device to match the hose via the telescopic control of an electric push rod. However, when the hose is transmitted to the cutting device, the transmission mechanism needs to be stopped. After the cutting device completes the cutting, the transmission mechanism is restarted to transmit the hose. This method requires special programming to coordinate the transmission structure and the cutting mechanism, making the operation complex and costly. This hinders large-scale promotion and affects versatility. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an automatic feeding structure for a PVC hose shearing machine, which can effectively solve the problem of high cost and high price of the intermittent transmission method that is controlled by programming in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an automatic feeding structure for a PVC hose shearing machine, including a mounting plate. The upper end of the mounting plate has a moving groove, and a moving block is slidably connected in the moving groove. A force-bearing plate is fixedly connected to the upper end of the moving block. A backing rod is rotatably connected to the upper end of the mounting plate via a rotating shaft. The backing rod abuts against the force-bearing plate. A clamping ring is fixedly connected to the lower end of the moving block. Two sets of clamping mechanisms are provided on the outer side of the clamping ring. The clamping mechanisms are used to clamp the pipe.

[0006] Furthermore, each clamping mechanism comprises a clamping block, a movable rod, a mounting shell, a second spring, a horizontal block, a swing plate, a sliding rod, a sliding groove, and two positioning grooves. The mounting shell is fixedly connected to the circumferential surface of the clamping ring, the movable rod movably penetrates the circumferential surface of the clamping ring, the horizontal block and the clamping block are respectively fixedly connected to the two ends of the movable rod, the second spring is fixedly connected to one side of the inner wall of the mounting shell and one end of the horizontal block, the sliding groove and the two positioning grooves are both opened at one end of the horizontal block, the swing plate is rotatably connected to one end of the mounting shell through a rotating rod, and the sliding rod is fixedly connected to one end of the swing plate and slidably connected in the sliding groove.

[0007] Furthermore, a force-bearing rod is fixedly connected to one end of the horizontal block, the force-bearing rod movably passes through one end of the mounting shell, and a forced block is fixedly connected to one end of the force-bearing rod. Two mounting rods are fixedly connected to one end of the mounting plate, and a mounting plate is fixedly connected to one end of each of the two mounting rods.

[0012] Beneficial effects

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. When the hose needs to be transferred, the clamping mechanism drives the clamping ring and the hose to move. When the hose moves to the far right, the shearing device cuts the hose and releases the clamping mechanism from the hose. Then, the abutment rod rotates and abuts against the force plate again, resetting the force plate and clamping ring. Similarly, the clamping mechanism resets to its initial position and clamps the hose again through the force block and another abutment rod, making it easy to push the hose back to the shearing position. Through the above design, the hose can be continuously and intermittently pulled to the right, improving the shearing efficiency of the hose. Moreover, the mechanical mechanism replaces the programming control, simplifying the operation steps and facilitating subsequent maintenance and repair. Second, the moving block can be pushed by the first spring, making the movement of the moving block more reasonable. When the moving block moves, it can slide on the circumferential surface of the horizontal rod through the horizontal hole, which improves the horizontal movement stability of the horizontal rod.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] See attached document Figure 1-5 An automatic feeding structure for a PVC hose shearing machine includes a mounting plate 1. A moving groove 4 is provided at the upper end of the mounting plate 1. A moving block 12 is slidably connected in the moving groove 4. A force plate 7 is fixedly connected to the upper end of the moving block 12. An abutment rod 8 is rotatably connected to the upper end of the mounting plate 1 via a rotating shaft. The abutment rod 8 abuts against the force plate 7. A clamping ring 15 is fixedly connected to the lower end of the moving block 12. Two sets of clamping mechanisms are provided on the outer side of the clamping ring 15. The clamping mechanisms are used to clamp the pipe. Each clamping mechanism consists of a clamping block 16, a movable rod 17, a mounting shell 18, a second spring 25, a horizontal block, a swing plate 24, a sliding rod 23, a sliding groove 21, and two positioning grooves 22. The mounting shell 18 is fixedly connected to the circumferential surface of the clamping ring 15. The movable rod 17 moves through the circumferential surface of the clamping ring 15. The horizontal block and the clamping block 16 are fixedly connected to the two ends of the movable rod 17, respectively. The second spring 25 is fixedly connected to one side of the inner wall of the mounting shell 18 and one end of the horizontal block. The sliding groove 21 and the two positioning grooves 22 are all opened at one end of the horizontal block. The swing plate 24 is rotatably connected to one end of the mounting shell 18 through a rotating rod. The sliding rod 23 is fixedly connected to one end of the swing plate 24 and is slidably connected in the sliding groove 21. A force-bearing rod 20 is fixedly connected to one end of the horizontal block. The force-bearing rod 20 movably passes through one end of the mounting shell 18, and a forced block 19 is fixedly connected to one end of the force-bearing rod 20. Two mounting rods 3 are fixedly connected to one end of the mounting plate 1. A mounting plate 2 is fixedly connected to one end of each of the two mounting rods 3. An abutment rod 14 is fixedly connected to one end of each of the two mounting plates 2.

[0020] In a specific embodiment of this utility model, when the hose needs to be transported, the horizontal block is in its initial position, and the sliding rod 23 is located in the positioning groove 22 on the left. The movable rod 17 and the clamping block 16 are relatively far from the inner circumference of the clamping ring 15. The hose is clamped by the clamping block 16, and then the abutment rod 8 rotates to gradually release the abutment against the force plate 7. The force plate 7 will gradually move to the right, and simultaneously drive the clamping ring 15 and the hose to move. When the hose moves to the far right, the shearing device cuts the hose, and at the same time, the forced block 19 will contact and abut against one of the abutment rods 14, causing the horizontal block to move briefly. At the same time, the sliding rod 23 slides in the sliding groove 21, and through the elastic pull of the second spring 25, the sliding rod 23 slides a certain distance and then engages with another positioning groove 2. Within 2, the distance between the horizontal block and the inner wall of the mounting shell 18 decreases, causing the clamping block 16 and the movable rod 17 to move to the left, releasing the clamping block 16 from the hose. Then, the abutment rod 8 rotates and abuts against the force plate 7 again, resetting the force plate 7 and the clamping ring 15. Similarly, the horizontal block moves to the right through the abutment of the forced block 19 and another abutment rod 14, causing the sliding rod 23 to slide in the sliding groove 21 and reset to another positioning groove 22. The clamping block 16 resets to its initial position to clamp the hose, making it easy to push the hose back to the shearing position. Through the above design, the hose can be continuously and intermittently pulled to the right, improving the shearing efficiency of the hose. Furthermore, the mechanical mechanism replaces the programming control, simplifying the steps required for operation and facilitating subsequent maintenance and repair.

[0021] Please refer to the details. Figure 1-5 A first spring 5 is fixedly connected between one side inner wall of the moving groove 4 and one end of the moving block 12. A horizontal rod 6 is fixedly connected between the two sides inner walls of the moving groove 4. A horizontal hole is opened at one end of the moving block 12, and the moving block 12 is slidably connected to the circumferential surface of the horizontal rod 6 through the horizontal hole.

[0022] In this embodiment: the first spring 5 can push the moving block 12 to make the movement of the moving block 12 more reasonable. When the moving block 12 moves, it can slide on the circumferential surface of the horizontal rod 6 through the horizontal hole, thereby improving the horizontal movement stability of the horizontal rod 6.

[0023] Please refer to the details. Figure 1-5 Mounting plate 1 has mounting strips 9 fixedly connected to both ends. Mounting brackets 10 are fixedly connected to the upper ends of the two mounting strips 9. Motor 11 is fixedly connected to the lower end of mounting bracket 10. The output end of motor 11 is fixedly connected to the rotating shaft. A connecting hole is opened at the upper end of mounting plate 1. A screw 26 is installed in the connecting hole. A nut 13 is fixedly connected to the upper end of screw 26.

[0024] In this embodiment: the motor 11 can be installed by the mounting strip 9 and the mounting bracket 10. The rotation of the output shaft of the motor 11 can automatically drive the abutment rod 8 to rotate. The nut 13 and screw 26 provided in the connecting hole can be used to easily connect and install this device and the shearing device.

[0025] Working principle: When the hose needs to be transferred, the horizontal block is in its initial position, and the sliding rod 23 is located in the positioning groove 22 on the left. The movable rod 17 and the clamping block 16 are relatively far from the inner circumference of the clamping ring 15. The hose is clamped by the clamping block 16. Then, by rotating the abutment rod 8, the abutment with the force plate 7 is gradually released. The force plate 7 will gradually move to the right, and simultaneously drive the clamping ring 15 and the hose to move. When the hose moves to the far right, the shearing device cuts the hose. At the same time, the forced block 19 will contact and abut with one of the abutment rods 14, causing the horizontal block to move briefly. At the same time, the sliding rod 23 slides in the sliding groove 21. Through the elastic pull of the second spring 25, the sliding rod 23 slides a certain distance and then engages in another positioning groove 22. As the distance between the horizontal block and the inner wall of the mounting shell 18 decreases, the clamping block 16 and the movable rod 17 move to the left, releasing the clamping block 16 from the hose. Then, the abutment rod 8 rotates and abuts against the force plate 7 again, resetting the force plate 7 and the clamping ring 15. Similarly, the horizontal block moves to the right through the abutment of the forced block 19 and another abutment rod 14, causing the sliding rod 23 to slide in the sliding groove 21 and reset to another positioning groove 22. The clamping block 16 resets to its initial position to clamp the hose, making it easy to push the hose back to the shearing position. Through the above design, the hose can be continuously and intermittently pulled to the right, improving the shearing efficiency of the hose. Furthermore, the mechanical mechanism replaces the programming control, simplifying the steps required for operation and facilitating subsequent maintenance and repair.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
