Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hook and loop tape production and processing device, especially to full -automatic raw material cutting device. BACKGROUND

[0002] Hook and loop tape, also known as Velcro, is a reusable connecting material composed of hooks and loops. It is widely used in various fields, including clothing, footwear, packaging, furniture, medical devices, outdoor equipment, etc. Due to its convenience, durability, and wide range of applications, hook and loop tape has become an indispensable connecting and fixing material in many industries. This material is produced by using a slitting device to cut the finished hook and loop tape.

[0003] In traditional slitting devices, the cutting mechanism is the core part of the entire device, used for accurately cutting the hook and loop tape. This may include rotating blades, cutting knives, or other forms of cutting tools that can perform precise cutting operations as needed. The conveying system is used to transport the hook and loop tape from the original roll or supply device to the cutting position. This ensures the stability and continuity of the hook and loop tape during the cutting process. The support structure and base provide a stable foundation for the entire device, ensuring stability and reliability during operation.

[0004] However, the slitting device often simply fixes the hook and loop tape before cutting, which does not provide strong fixation for the hook and loop tape. This can lead to a decrease in slitting quality due to displacement of the hook and loop tape during the slitting process, reducing the slitting quality and consistency of the hook and loop tape. SUMMARY

[0005] The purpose of the present utility model is to provide a hook and loop tape slitting auxiliary positioning device, aiming to solve the problem of weak fixation of the hook and loop tape in traditional slitting devices, which can lead to a decrease in slitting quality due to displacement of the hook and loop tape during the slitting process, reducing the slitting quality and consistency of the hook and loop tape.

[0006] To achieve the above-mentioned purpose, the hook and loop tape slitting auxiliary positioning device provided by the embodiments of the present utility model comprises a guide rail, a workbench is slidably connected to the top of the guide rail, a plurality of fixed tables are fixedly connected to the side walls of the workbench, a plurality of circular grooves are formed in the interiors of the fixed tables, an electric push rod is fixedly connected to the bottom of the fixed table, a push table is fixedly connected to the output end of the electric push rod, a sliding shaft is fixedly connected to the interior of the push table, a rotary table is fixedly connected to the upper surface of the fixed table, a rotary shaft is rotatably connected to the interior of the rotary table, a connecting plate is fixedly connected to the outer wall of the rotary shaft, the sliding shaft is slidably connected in the interior of the connecting plate, a positioning plate is fixedly connected to the top of the connecting plate, a fixing assembly is arranged on the top of the guide rail, and the fixing assembly is used to fix the hook and loop tape slitting structure.

[0007] Optionally, the fixing assembly comprises a connecting table fixedly connected to the guide rail side wall.

[0008] Optionally, a gas cylinder is fixedly connected to the connecting table side wall, and an L-shaped rod is rotatably connected to an output end of the gas cylinder.

[0009] Optionally, a sliding groove is formed in the connecting table, and the L-shaped rod is slidably connected in the sliding groove.

[0010] Optionally, a connecting column is rotatably connected in the sliding groove, and a rotating frame is fixedly connected to an outer wall of the connecting column.

[0011] Optionally, a plurality of vertical grooves are formed in the connecting table, and a fixing frame is rotatably connected to an outer wall of the rotating frame.

[0012] Optionally, a plurality of pulleys are rotatably connected in the fixing frame, and the pulleys are slidably connected in the vertical grooves.

[0013] Optionally, a cutter is fixedly connected in the fixing frame.

[0014] The above one or more technical solutions in the auxiliary positioning device for the split cutting of the hook-and-loop fastener provided by the embodiment of the present application have at least one of the following technical effects:

[0015] 1. Firstly, the pusher is pushed by the electric push rod, and the displacement of the pusher drives the sliding shaft at the top of the pusher to slide in the connecting plate. The angle of the connecting plate is changed, and the positioning plate at the top of the connecting plate is finally driven to slide on the surface of the workbench. At this time, the positioning plate can effectively fix the hook-and-loop fastener on the surface of the workbench, so that the displacement of the hook-and-loop fastener in the splitting process is avoided, and the splitting quality of the hook-and-loop fastener is ensured.

[0016] 2. The L-shaped rod is driven to slide in the sliding groove by the gas cylinder, and the sliding groove changes the inclination angle. The plurality of pulleys in the fixing frame slide in the vertical grooves, so that the fixing frame smoothly displaces and drives the cutter at the bottom of the fixing frame to split the hook-and-loop fastener. Therefore, the structure ensures that the splitting stress of the hook-and-loop fastener is uniform, and the splitting quality is improved. BRIEF DESCRIPTION OF DRAWINGS

For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0027] In one embodiment of the present application, as shown in Figs. 1-2 A kind of Velcro tape slitting auxiliary positioning device is provided, including guide rail 1, guide rail 1 top slidingly connected with workbench 2, the side wall of workbench 2 is fixedly connected with multiple fixed platforms 3, multiple circular grooves 5 are arranged in fixed platform 3, electric push rod 4 is fixedly connected at the bottom of fixed platform 3, push table 6 is fixedly connected at the output end of electric push rod 4, sliding shaft 7 is fixedly connected in push table 6, rotary table 8 is fixedly connected on the upper surface of fixed platform 3, rotary shaft 9 is rotatably connected in rotary table 8, connecting plate 10 is fixedly connected on the outer wall of rotary shaft 9, sliding shaft 7 is slidingly connected in connecting plate 10, positioning plate 11 is fixedly connected at the top of connecting plate 10, fixed assembly is arranged at the top of guide rail 1, and the fixed assembly is used to fix the Velcro tape slitting structure.

[0028] Specifically, the Velcro tape is placed on the surface of workbench 2, then the electric push rod 4 is started, the push rod moves the push table 6 in the circular groove 5 by the pushing force on the push table 6, in this process, the displacement of the push table 6 drives the sliding shaft 7 at the top to slide in the connecting plate 10, the sliding of the sliding shaft 7 causes the connecting plate 10 to start rotating, and in turn drives the rotary shaft 9 in the rotary table 8 to rotate, by adjusting the angle of the connecting plate 10, the positioning plate 11 at the top can be made to slide to the surface of the workbench 2, the movement of the positioning plate 11 ensures the effective fixing of the Velcro tape on the workbench 2, so that unnecessary displacement of the Velcro tape can be avoided during the slitting process, thereby ensuring the quality and accuracy of the slitting.

[0029] In another embodiment of the present application, as shown in Fig. 3 The fixed assembly includes connecting table 12, connecting table 12 is fixedly connected on the side wall of guide rail 1, air cylinder 13 is fixedly connected on the side wall of connecting table 12, L-shaped rod 15 is rotatably connected at the output end of air cylinder 13, sliding groove 14 is arranged in connecting table 12, L-shaped rod 15 is slidingly connected in sliding groove 14, connecting column 16 is rotatably connected in sliding groove 14, rotary frame 17 is fixedly connected on the outer wall of connecting column 16, multiple vertical grooves 20 are arranged in connecting table 12, fixed frame 18 is rotatably connected on the outer wall of rotary frame 17, multiple pulleys 19 are rotatably connected in fixed frame 18, pulleys 19 are slidingly connected in vertical grooves 20, and cutter 21 is fixedly connected in fixed frame 18.

[0030] Specifically, the cylinder 13 applies a pushing force downward through the L-shaped rod 15, causing the L-shaped rod 15 to slide downward inside the sliding groove 14. The sliding groove 14 thus changes the inclination angle, thereby pressing down the connecting column 16 inside it. The movement of the connecting column 16 causes the rotating frame 17 to start rotating, and the change in the inclination angle of the rotating frame 17 produces a rotating effect inside the fixed frame 18, pushing the bottom of the fixed frame 18. The fixed frame 18 is provided with a plurality of pulleys 19 inside it, which slide inside the vertical groove 20, thereby causing the fixed frame 18 to move smoothly. This movement simultaneously drives the cutter 21 at the bottom of the fixed frame 18 to perform a precise slitting operation on the hook-and-loop tape, ensuring that each divided hook-and-loop tape is of consistent length and maintains stability during the operation, thereby meeting the requirements of precision in industrial production of hook-and-loop tape.

[0031] Working principle: when it is necessary to fix the hook-and-loop tape, place it on the surface of the workbench 2. At this time, start the electric push rod 4, which outputs a pushing force to the push table 6, driving the push table 6 to slide vertically inside the circular groove 5. The push table 6 simultaneously drives the sliding shaft 7 at the top of the push table 6 to slide inside the connecting plate 10. At this time, the sliding of the sliding shaft 7 drives the connecting plate 10 to rotate, and the connecting plate 10 drives the rotating shaft 9 inside it to rotate in the rotating table 8. The change in the angle of the connecting plate 10 drives the positioning plate 11 at the top of the connecting plate 10 to slide towards the surface of the workbench 2. At this time, the positioning plate 11 can effectively fix the hook-and-loop tape on the surface of the workbench 2, preventing it from shifting during the slitting process and ensuring the quality of the slitting of the hook-and-loop tape. When it is necessary to slit the fixed hook-and-loop tape, start the cylinder 13, which outputs a pushing force to the L-shaped rod 15, driving the L-shaped rod 15 to slide inside the sliding groove 14. At this time, the sliding groove 14 changes the inclination angle, thereby pressing down the connecting column 16 inside it, causing the rotating frame 17 to rotate. The change in the inclination angle of the rotating frame 17 rotates inside the fixed frame 18, thereby pushing the bottom of the fixed frame 18. The plurality of pulleys 19 inside the fixed frame 18 slide inside the vertical groove 20, thereby causing the fixed frame 18 to move smoothly and drive the cutter 21 at the bottom of the fixed frame 18 to slit the hook-and-loop tape. This structure ensures that the force applied during the slitting of the hook-and-loop tape is uniform, thereby improving the slitting quality.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
