Description

Technical Field

[0001] This utility model relates to the field of thread or rope length cutting technology, specifically a thread cutting device with simple structure, high cutting efficiency, small space occupation, and accurate cutting length. Background Technology

[0002] As is well known, equipment manufacturers that use thread or rope generally need to cut the thread or rope. Currently, the production process for thread or rope of a specific length usually involves manually measuring the length of the coiled thread or rope and then cutting it with scissors. This cutting efficiency is very low. Moreover, some threads or ropes need to be bundled together, which requires cutting each one individually before merging and binding. To increase cutting efficiency, the existing cutting method is generally to wind multiple threads or ropes together on a disc of the required circumference length, winding it one or more times before manually cutting. This is practical for short-length threads or ropes, but for long-length threads or ropes, it increases the space occupied by the disc. Furthermore, manual cutting also reduces the cutting accuracy. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wire cutting device that is simple in structure, highly efficient in cutting, occupies little space, and has accurate cutting length.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A wire pulling and cutting device is provided with a bracket. The bracket is characterized in that an inlet pipe is fixedly connected to the bracket, and extrusion pull rollers are respectively provided on both sides below the inlet pipe. One or both extrusion pull rollers are connected to the output end of a driver fixed on the bracket. A guide tube is provided below the two extrusion pull rollers at a position corresponding to the inlet pipe. The guide tube is fixed on the bracket. A wire cutter and an outlet pipe are fixed sequentially on the bracket below the guide tube. The upper inlet of the outlet pipe corresponds to the lower outlet of the guide tube.

[0006] The bracket of this utility model includes a vertical plate, an upper horizontal plate, a cutting and fixing plate, and a lower horizontal plate. The upper horizontal plate, the cutting and fixing plate, and the lower horizontal plate are fixedly connected to the side of the vertical plate from top to bottom. The inlet pipe is vertically connected to the upper horizontal plate, the wire pipe is vertically connected to the cutting and fixing plate, the wire cutter is fixedly connected to the side of the cutting and fixing plate, and the outlet pipe is fixedly connected to the lower horizontal plate.

[0007] The wire cutter of this utility model includes a cutting motor, a cam, a cutting blade, and a blade positioning plate. The blade positioning plate is fixedly connected to a cutting fixing plate. The blade positioning plate is provided with a wire hole that mates with a wire conduit. The cutting blade is elastically connected to the blade positioning plate via a return spring. The cutting edge at the front end of the cutting blade faces the wire hole of the blade positioning plate. The rear end of the cutting blade contacts the side of the cam. The cam is connected to the output end of the cutting motor fixed on the cutting fixing plate. The cam drives the cutting blade to perform a cutting action forward.

[0008] Guide seats are fixed on the blade positioning plates on both sides of the cutting blade of the present invention. The guide seats slide in contact with both sides of the cutting blade and limit the sliding direction of the cutting blade by means of the guide seats.

The elastic pad extrudes the thread or rope and can drive the thread or rope to move, thus preventing the thread or rope from slipping. A meter counter is installed on the extrusion pull roller to record the length of the thread or rope passing through the extrusion pull roller by the number of rotations of the extrusion pull roller.

[0010] In this invention, one of the two extrusion and drawing rollers is rotatably connected to the bracket via an arc plate. The upper end of the arc plate is hinged to the bracket via a pin shaft. The internal threading operation is achieved by lifting the arc plate.

[0011] The present invention relates to a fixed driver on an arc-shaped plate, wherein the output end of the driver is fixedly connected to the extrusion wire roller.

[0012] The lower end of the inlet tube and the upper end of the conductor tube of this invention are tapered, which facilitates insertion between the two extrusion and drawing rollers and contact with the roller surface of the extrusion and drawing rollers.

[0013] The bracket described in this utility model is connected to the winding mechanism, which drives the wire out of the tube to be wound.

[0014] The winding mechanism of this utility model includes a winding frame, a transverse sliding drive mechanism, a longitudinal sliding drive mechanism, and wire clamps.

[0023] Furthermore, the wire cutter includes a cutting motor 11, a cam 12, a cutting blade 13, and a blade positioning plate 14. The blade positioning plate 14 is fixedly connected to the cutting fixing plate 9. The blade positioning plate 14 is provided with a wire hole that cooperates with the wire tube 5. The cutting blade 13 is elastically connected to the blade positioning plate 14 via a return spring. The cutting edge at the front end of the cutting blade 13 faces the wire hole of the blade positioning plate 14. The rear end of the cutting blade 13 contacts the side of the cam 12. The cam 12 is connected to the output end of the cutting motor 11 fixed on the cutting fixing plate 9. The cam 12 drives the cutting blade 13 to perform a cutting action towards the front.

[0024] The aforementioned upper transverse plate 8 has an upper through hole. The lower part of the upper transverse plate 8 is detachably connected to the inlet seat 15 for fixing the inlet tube 2. The inlet tube 2 is fixed on the inlet seat 15. The upper end of the inlet tube 2 passes through the upper through hole above the upper transverse plate 8, and the lower end of the inlet tube 2 extends out of the inlet seat 15 and extends between the two extrusion and pulling rollers 3. The aforementioned cutting and fixing plate 9 has a central through hole. The upper part of the cutting and fixing plate 9 is detachably connected to the wire seat 16 for fixing the wire tube 5. The wire is fixed on the wire seat 16. The upper end of the tube 5 extends between the two extrusion and pulling rollers 3. The lower end of the tube 5 passes through the central through hole and enters the wire hole of the blade positioning plate 14. The lower transverse plate 10 is provided with a lower through hole. The lower part of the lower transverse plate 10 is detachably connected to the wire outlet seat 17 that fixes the wire outlet tube 6. The wire outlet tube 6 is fixed on the wire outlet seat 17.

The lower end of the wire outlet tube 6 extends out of the wire outlet seat 17 and extends to the wire clamp position in the subsequent winding mechanism.

[0025] The upper inlets of the aforementioned inlet pipe 2, conductor pipe 5, and outlet pipe 6 are funnel-shaped to facilitate the insertion of wires or ropes. The funnel-shaped opening at the upper end of the outlet pipe 6 is larger than the outlet at the lower end of the conductor pipe 5. The outlet at the lower end of the conductor pipe 5 is conical to facilitate the smooth entry of cut wires or ropes into the inlet of the outlet pipe 6 below.

[0026] In the above scheme, the detachable connection of the inlet socket 15, the wire socket 16 and the outlet socket 17 allows for the replacement of different numbers of inlet pipes 2, wire sockets 5 and outlet pipes 6.

[0027] Furthermore, guide seats 18 are fixed on the blade positioning plates on both sides of the cutting blade 13. The guide seats 18 slide in contact with both sides of the cutting blade 13, and the sliding direction of the cutting blade is restricted by the guide seats 18.

[0028] Furthermore, an elastic pad 19 is fixedly connected to the roller surface of the extrusion pull roller 3. The elastic pad 19 extrudes the thread or rope and can drive the thread or rope to move, preventing the thread or rope from slipping. A meter counter is installed on the extrusion pull roller 3 to record the length of the thread or rope passing through the extrusion pull roller 3 by the number of rotations of the extrusion pull roller 3. The elastic pad 19 can be a rubber elastic pad 19, which increases the friction while also extruding the thread or rope.

[0029] Furthermore, one of the two extrusion wire drawing rollers 3 is rotatably connected to the bracket 1 via an arc plate 29. The upper end of the arc plate 29 is hinged to the bracket 1 via a pin shaft 30. The internal wire threading operation is achieved by lifting the arc plate 29.

[0030] Furthermore, a driver 4 is fixed on the arc plate 29, and the output end of the driver 4 is fixedly connected to the extrusion wire roller 3.

[0031] The aforementioned driver 4 is a drive motor, which controls the rotation of the extrusion pull roller 3. The two extrusion pull rollers 3 are driven by two drive motors respectively, and rotate synchronously inward to extrude the line or rope that has passed through the extrusion pull roller 3. Alternatively, one of the extrusion pull rollers 3 can be connected to the output end of the drive motor, and the other extrusion pull roller 3 can be rotatably connected to the bracket 1 or the arc plate 29.

[0032] Furthermore, the lower end of the inlet tube 2 and the upper end of the wire tube 5 are tapered, which facilitates insertion between the two extrusion wire drawing rollers 3 and contact with the roller surface of the extrusion wire drawing rollers 3.

[0033] Furthermore, the bracket 1 is connected to the winding mechanism, which drives the wire of the outlet tube 6 to be wound.

[0034] Furthermore, the winding mechanism includes a winding frame 20, a transverse sliding drive mechanism, a longitudinal sliding drive mechanism, and a wire clamp 27. The longitudinal sliding drive mechanism is fixed on the left and right sides of the winding frame 20, and the output end of the longitudinal sliding drive mechanism is connected to the transverse sliding drive mechanism. The output end of the transverse sliding drive mechanism is fixedly connected to the bracket 1. Wire clamps are evenly distributed in the middle of the winding frame 20. The wire outlet tube 6 on the bracket 1, driven by the transverse sliding drive mechanism and the longitudinal sliding drive mechanism, clamps the pulled-out wire or rope into the wire clamp 27.

[0035] One embodiment of the above-mentioned winding mechanism is as follows: The transverse sliding drive mechanism includes a transverse motor 21, a transverse track 22, a transverse main gear, a transverse driven gear, a transverse toothed belt, and a fixing block 23. The transverse motor 21 is fixed at the end of the transverse track 22. The output shaft of the transverse motor 21 is connected to the transverse main gear. The transverse main gear and the transverse driven gear are rotatably connected to the two ends of the transverse track 22, respectively. A transverse toothed belt is fitted on the transverse main gear and the transverse driven gear. The fixing block 23 is fixedly connected to the transverse toothed belt and is connected to the bracket 1. The longitudinal sliding drive mechanism includes a longitudinal motor 24, a longitudinal track 25, a longitudinal main gear, a longitudinal driven gear, a longitudinal toothed belt, and a longitudinal moving block 26. The longitudinal track 25 is symmetrically fixed on the left and right sides of the winding frame 20, respectively. The longitudinal main gear and the longitudinal moving block 26 are rotatably connected to the front and rear sides of the longitudinal track 25, respectively. A longitudinal toothed belt is fitted onto the longitudinal master gear and the longitudinal slave gear. The longitudinal master gears on the left and right sides are connected by a coupling 28. One of the longitudinal gears is connected to the output end of the longitudinal motor 24 fixed on the longitudinal track 25. A longitudinal moving block 26 is fixed on the longitudinal toothed belt. The longitudinal moving block 26 is connected to both ends of the transverse track 22. The wire clamp 27 includes an elastic wire clamping ring. The wire clamping ring is a structure in which the upper end is open when inserted into the side of the wire outlet tube 6 and closes due to the elastic action after the wire outlet tube 6 is removed. The wire clamping rings are distributed on the winding frame 20 along the path of the wire outlet ring movement direction. The connection structure of the transverse master gear, transverse slave gear, transverse toothed belt, longitudinal master gear, longitudinal slave gear, and longitudinal toothed belt is existing technology and will not be described in detail here. Rotating wheels are provided on the upper and lower sides of the fixed block 23, and the rotating wheels rotate on the upper and lower sides of the transverse track 22.

[0036] The above-mentioned cutting of the line or rope can be for use in binding hooks or making line sets, but is not limited to this. After cutting, the line or rope can be used in the factory for product installation or as a product for consumers, enabling mass production. In use, the horizontal motor 21 and the vertical motor 24 drive the bracket 1 to move, causing the line tube 6 to follow an S-shaped path. At the position where the line tube 6 passes, the line or rope is clamped in the line clamp 27, thereby tidying up the line or rope. While moving, the two compression and pulling rollers 3 rotate simultaneously, squeezing and pulling the line or rope that has passed through the compression and pulling rollers 3. The meter counter on roller 3 measures the length of the thread or rope passing through the extrusion roller 3. When the required length is reached, the cutting motor 11 is started. The cutting motor 11 drives the cam 12 to move. The cam 12 drives the cutting blade 13 to move forward and cut the thread or rope. After cutting, the cutting blade 13 is reset under the action of the return spring. At the same time, the thread or rope cut above continues to move downward under the action of the extrusion roller 3 and is inserted into the output roller. Then it is led out for the next round of thread or rope cutting. Due to the above structure, this utility model has the advantages of simple structure, high cutting efficiency, small space occupation, and accurate cutting length.
