[0025] Reference Figure 5The profile strip threading machine is used for threading the rubber strip 20 into the profile 10. The profile 10 comprises a clamping groove 11, and the rubber strip 20 comprises a cavity 21, the upper side of the cavity 21 is provided with an outer end face 23, and the lower side is provided with a clamping edge 22. In use, the clamping edge 22 needs to be clamped into the clamping groove 11, so that the rubber strip 20 can be relatively fixed in the profile 10. In the traditional rubber strip threading machine, the clamping edge 22 can enter the clamping groove 11 by providing a positive pressure to the outer end face 23 of the rubber strip 20, but due to the cavity 21 between the outer end face 23 and the clamping edge 22, the force received by the outer end face 23 cannot be well transmitted to the clamping edge 22, so that part of the clamping edge 22 cannot enter the clamping groove 11 in the processing process, affecting the use of the product.

[0026] Therefore, the improved profile rubber strip threading machine is provided. Figures 1-4 The rubber strip threading machine comprises a rack 100, the rack 100 is provided with a workbench 110, the lower side of the workbench 110 is provided with four legs, and the legs provide support to the workbench 110. A profile feeding mechanism 200 is arranged in front of the workbench 110, and a rubber strip feeding mechanism 300 is arranged on the upper side of the rear of the workbench. The profile feeding mechanism 200 comprises a feeding channel 210 arranged from front to rear, the profile 10 is placed on the profile feeding mechanism 200 and then conveyed from front to rear, and when placed, the clamping groove 11 of the profile 10 faces upward. Specifically, the profile feeding mechanism 200 comprises a friction wheel 220, the upper side of the friction wheel 220 is provided with a positioning wheel 230, and the feeding channel 210 is arranged between the friction wheel 220 and the positioning wheel 230. Figure 2

[0027] The rubber strip feeding mechanism 300 comprises a storage disc 310, the rubber strip 20 is wound in the storage disc 310, and then is orderly discharged along with the rotation of the storage disc 310.

[0028] Then the workbench 110 is further provided with a pressing mechanism 400, the pressing mechanism 400 is located at the rear of the profile feeding mechanism 200, the pressing mechanism 400 is connected with the rubber strip feeding mechanism 300, and the rubber strip 20 discharged from the storage disc 310 is sent into the pressing mechanism 400. Specifically, the pressing mechanism 400 comprises a pressing wheel 410, the pressing wheel 410 is arranged on the upper side of the workbench 110, and the pressing wheel 410 is arranged in the feeding channel 210. Figures 2-4 ​The extrusion mechanism 400 comprises a wheel seat 410 and a roller 420 rotatably connected to the wheel seat 410. The wheel seat 410 is provided with a wheel groove 411, the upper end of the wheel groove 411 is provided with an inlet 401, and the lower end of the wheel groove 411 is provided with an outlet 402. The inner diameter of the wheel groove 411 is greater than the outer diameter of the roller 420. A rubber strip channel 403 is arranged between the wheel groove 411 and the roller 420, the width of the rubber strip channel 403 is slightly smaller than the thickness of the rubber strip 20, and the rubber strip channel 403 is in communication with the inlet 401 and the outlet 402. An extrusion block 430 is arranged near the outlet 402 of the wheel seat 410, and the extrusion block 430 comprises a pointed end 431 which is opposite to the outlet 402. The outlet 402 is opposite to the feeding channel 210.

[0029] During operation, the rubber strip 20 is discharged from the storage tray 310, and then enters the inlet 401, the rubber strip channel 403 and the outlet 402 in sequence. When the rubber strip 20 is discharged, it is extruded by the extrusion block 430, so that the clamping edge 22 of the rubber strip 20 is extruded and deformed. The profiled bar 10 is transported from front to back under the action of the friction wheel 220. When the clamping groove 11 of the profiled bar 10 passes through the outlet 402, the rubber strip 20 is extruded and deformed by the extrusion block 430, so that the clamping edge 22 is deformed and shrinks upward, and the instantaneous size of the clamping edge 22 is smaller than the inner diameter of the clamping groove 11, so that the clamping edge 22 can easily enter the clamping groove 11. When the clamping edge 22 leaves the extrusion block 430, it is no longer extruded and deformed by the extrusion block 430, and it restores its shape under the action of its own elastic force, so that the clamping edge 22 can be clamped in the clamping groove 11. The extrusion block 430 is fixed on the outlet 402 and does not move, so that the rubber strip 20 is extruded and deformed when it passes through the outlet 402, and the deformed rubber strip 20 immediately enters the clamping groove 11. As the profiled bar 10 continuously moves backward and the rubber strip 20 is continuously discharged to the outlet 402 by the rotation of the roller 420, as long as the running speeds of the two are adjusted, the rubber strip 20 can automatically enter the profiled bar 10 to complete the threading operation. Because the clamping edge 22 of the rubber strip 20 is always extruded and deformed by the extrusion block 430 during threading, the deformation of the rubber strip 20 is stable, the threading operation is stable, the possibility of rubber strip overflow is small, and the work efficiency is high.

[0030] In order to avoid interference between the extrusion block 430 and the profiled bar 10, the pointed end 431 of the extrusion block 430 can be modified to be arc-shaped.

[0031] In this embodiment, the roller 420 continuously rotates in the wheel groove 411, thereby continuously discharging the rubber strip 20 in the rubber strip channel 403 from the outlet 402.

[0032] In order to make the adhesive tape 20 more closely into the card slot 11, further as a preferred embodiment, also includes a roller mechanism 500, the roller mechanism 500 is provided behind the extrusion mechanism 400. The roller mechanism 500 includes an upper pressure roller 510 and a lower drive roller 520, the upper pressure roller 510 is connected to the frame 100. The lower drive roller 520 and the friction wheel 220 linkage settings, namely the lower drive roller 520 follows the friction wheel 220 rotation and rotation, preferably, the two are driven by synchronous belt connection. The gap between the upper pressure roller 510 and the lower drive roller 520 is slightly smaller than the gap between the friction wheel 220 and the positioning wheel 230. When working, the adhesive tape 20 after the extrusion mechanism 400, into the card slot 11, the adhesive tape 20 end face 23 after the upper pressure roller 510 rolling, so that its surface more closely on the profile 10, at the same time, using the lower drive roller 520 can be completed with the profile of the strip away.

[0033] Because the adhesive tape is continuously wound together, when the completion of a profile of the strip, the adhesive tape needs to be cut off, in preparation for the next strip operation. For this reason, further as a preferred embodiment, also includes a cutting mechanism 600, the cutting mechanism 600 includes an electric control unit, a drive unit and a cutter 610, the drive unit and the cutter 610 drive connection, the electric control unit and the drive unit are electrically connected. In some embodiments, the length of the adhesive tape 20 is greater than the length of the profile, so that each time feeding, should ensure that the length of the adhesive tape 20 feeding is greater than the length of the profile. And through the electric control unit control drive unit action, can realize the control of the length of the adhesive tape 20, meet the needs of processing production.

[0034] In addition, in order to facilitate the accident, can be stopped at any time, further as a preferred embodiment, the wheel seat 410, the positioning wheel 230 and the upper pressure roller 510 are connected to the workbench 110. When working, the wheel seat 410, the positioning wheel 230 and the upper pressure roller 510 are lowered into position, to ensure that the profile can be clamped and pushed, but when the accident occurs, by lifting the wheel seat 410, the positioning wheel 230 and the upper pressure roller 510, can quickly take away the profile. At the same time, it is also convenient to adjust the initial processing.

[0035] Specifically, the extrusion mechanism 400 further comprises a mounting base plate 440, the wheel seat 410 is fixed on the mounting base plate 440, and the mounting base plate 440 is in sliding connection with the rack 100. The extrusion mechanism 400 comprises a driving motor 450, an output shaft of the driving motor 450 is in transmission connection with the roller 420 through a belt, the driving motor 450 is mounted on a base plate, and the base plate is in synchronous connection with the mounting base plate. When it is necessary to move the wheel seat 410 up and down, the driving motor 450 and the roller 420 are synchronously lifted and lowered, so that the driving connection between the driving motor 450 and the roller 420 is not affected by the lifting and lowering of the wheel seat 410.

[0036] Since the positioning wheel 230 and the upper pressing roller 510 are both non-powered mechanisms, the lifting structure of the two can be relatively simple, and the two can be directly lifted and lowered by a cylinder.

[0037] In addition, in order to ensure that the clamping groove 11 is always directed to the outlet when the profile 10 moves backward, as a further preferred embodiment, the profile feeding mechanism 200 comprises a centering guide roller set 240 located on the feeding channel. By using the centering guide roller set, the movement of the profile on the feeding channel can be more accurate.
