Description

Technical Field

[0001] This invention relates to the field of rubber roller coating technology, specifically to a rubber coating device for a traction rubber roller. Background Technology

[0002] In the coating operation, the traction rubber roller usually needs to continuously wind the rubber strip onto the roller surface and compact it with the pressure roller to ensure that the rubber layer is uniform and tightly adhered. Existing coating equipment generally includes a coating power component, transmission clamp, main pressure roller and its drive mechanism. During the winding process, the rubber strip is pressured by the main pressure roller, and at the same time, the rubber strip is covered layer by layer from one side of the roller to the other through the lateral movement mechanism.

[0003] For existing rubber coating equipment, the working angle of the pressure roller is usually fixed and cannot be flexibly adjusted according to the rubber strip coating process parameters. Moreover, when the rubber strip is wrapped, excess rubber liquid is easily overflowed between layers or at the joint due to the squeezing of the rubber material. If it is not cleaned in time, it will affect the flatness of the rubber layer and the coating quality.

[0004] Therefore, we propose a rubber coating device for traction rubber rollers to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a coating device for a traction rubber roller, which solves the problems mentioned in the background art, where the working angle of the pressure roller is usually fixed and cannot be flexibly adjusted according to the coating process parameters. Furthermore, when the rubber strip is wound, excess rubber is easily squeezed out between layers or at the joints, which, if not removed in time, will affect the flatness of the rubber layer and the coating quality.

[0017] The side of the adjusting sleeve has a locking internal thread hole, and a locking thread rod is screwed into the locking internal thread hole. The front end of the locking thread rod can abut against the surface of the inner insert cylinder by screwing into the locking internal thread hole, thereby locking the relative angle between the inner insert cylinder and the adjusting sleeve.

[0018] Furthermore, the top of the functional board is connected to the connecting arm via a reinforcement, and the other end of the connecting arm is connected to an adjusting slider. An adjusting cross plate is fixed on the side of the supporting connecting plate. The adjusting slider can be displaced within the groove of the adjusting cross plate, and the adjusting slider and the relative position of the adjusting cross plate can be locked by the screw at the front end of the adjusting slider.

[0019] Furthermore, the transmission structure includes a rotating block, an arc-shaped rail groove, a straight rail groove, a rotating inner arm, and a rotating sleeve arm. The rotating block is rotatably connected to the surface of the functional plate.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the present invention provides a rubber coating device for a traction rubber roller, which has the following beneficial effects:

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example

[0043] like Figure 1-8As shown, an embodiment of the present invention provides a rubber coating device for a traction rubber roller, including a rubber coating power assembly 1 and a transmission clamping rod 2 connected to the output end of the rubber coating power assembly 1. The rubber roller is mounted between two sets of transmission clamping rods 2, and the distance between the two sets of rubber coating power assemblies 1 can be adjusted so that the transmission clamping rods 2 lock the shaft of the rubber roller. The rubber roller is rotated under the drive of the rubber coating power assembly 1. A function box 5 on one side of the rubber coating power assembly 1 has a guide wheel for carrying rubber strips installed at its bottom. The front end of the rubber strip is adhered to the rubber roller by pressing it, and then... The main pressure roller 7 installed on the side can be used for pressing. The main driving force of the main pressure roller 7 is the electric pressure rod 6. The functional box 5 is equipped with a push assembly that drives the electric pressure rod 6. When the rubber strip is actually wrapped, it is necessary to wrap the rubber strip from one side of the rubber roller to the other side. Therefore, a support platform 3 and a screw drive structure 4 are installed at the bottom of the entire functional box 5. The functional box 5 is moved laterally along the support platform 3 by the drive of the screw drive structure 4. That is, the functional box 5 is moved laterally on one side of the rubber roller, so that the main pressure roller 7 can press all the rubber strips on the rubber roller.

[0044] The above structure is the conventional structure of the coating equipment.

[0045] The difference lies in the fact that a secondary pressure roller 17 with the same structure as the main pressure roller 7 is installed below the main pressure roller 7. An L-shaped support plate 9 is installed on both the main pressure roller 7 and the secondary pressure roller 17. The shafts of the main pressure roller 7 and the secondary pressure roller 17 pass laterally through the support plate 9, allowing the shafts to rotate. This allows the main pressure roller 7 and the secondary pressure roller 17 to rotate on one side of the support plate 9. In actual use, the main pressure roller 7 is used to press firmly onto the rubber strip. The upper and lower sets of pressure rollers provide better pressing effect on the rubber strip. An adjusting plate 14 is installed between the upper and lower sets of support plates 9, and the top of the adjusting plate 14 is bolted to the upper support plate. On the upper support plate 9, an adjusting screw part 16 is fixedly provided on the surface of the lower support plate 9. The surface of the adjusting plate 14 has an adjusting groove 15 with the slot facing downward. The adjusting screw part 16 can move longitudinally within the groove of the adjusting groove 15, thereby adjusting the distance between the main pressure roller 7 and the auxiliary pressure roller 17. At the same time, the adjusting screw part 16 can also be adjusted in angle within the groove of the adjusting groove 15, thereby changing the actual operating angle of the auxiliary pressure roller 17. Therefore, it can be adaptively adjusted according to actual processing requirements. After the position and angle of the adjusting screw part 16 are adjusted, the adjusting screw part 16 is locked with a nut and a washer.

[0046] like Figure 5As shown, an adjusting sleeve 10 is fixed at the front end of the electric pressure rod 6. A cylindrical slot is provided on the surface of the adjusting sleeve 10. An L-shaped bearing connecting plate 8 is fixed on the side of the top support plate 9. An inner insert 11 that is compatible with the cylindrical slot is also fixed on the top side of the bearing connecting plate 8. That is, the inner insert 11 rotates in the slot of the adjusting sleeve 10 and is axially prevented from falling off. A locking internal thread hole 12 is also provided on the outer wall of the adjusting sleeve 10. A locking thread rod 13 can be screwed into the locking internal thread hole 12. After the locking thread rod 13 is screwed in, its top area can abut against the outer wall of the inner insert 11. The rotation angle of the inner insert 11 can be locked by the locking thread rod 13, thereby adjusting the operating angle of the main pressure roller 7.

[0047] like Figure 3 as well as Figure 4 As shown, a horizontally arranged adjusting plate 18 is reinforced on the surface of the supporting connecting plate 8 by bolts. A horizontal slot is opened on the surface of the adjusting plate 18, and a set of adjusting sliders 20 are slidably inserted into the slot. A screw protrudes from the front end of the adjusting slider 20. The adjusting slider 20 can move laterally on the adjusting plate 18, and the relative position of the adjusting slider 20 is locked by the screw and nut. The rear end of the adjusting slider 20 is fixedly connected to the connecting arm 19. A functional plate 22 is installed below the end of the connecting arm 19. A reinforcing member 21 is installed at the top corner of the functional plate 22. The reinforcing member 21 is reinforced by bolts and a pre-set opening on the surface of the functional plate 22. The top of the reinforcing member 21 has a plug with a built-in threaded hole. After the plug is inserted into the opening at the end of the connecting arm 19, the functional plate 22 is reinforced to the end of the connecting arm 19 by installing a screw on the top of the connecting arm 19 and locking it with the reinforcing member 21.

[0048] like Figure 4 As shown, the functional plate 22 is a set of rectangular plate-shaped structures. A set of scraper parts 31 are installed on the side of the functional plate 22. The scraper parts 31 are made of rubber and play a role in pressing on the surface of the rubber strip in actual use. As the scraper parts 31 press on the rubber strip and move laterally, the scraper parts 31 can scrape off the glue overflowing from the gap of the rubber strip, thereby reducing the impact of excess glue on the winding of the rubber strip and improving the flatness of the winding of the rubber strip.

[0049] like Figure 7As shown, the surface of the functional plate 22 is reinforced with a reinforcing seat 32 by bolts. The top of the reinforcing seat 32 is provided with an inner sliding groove 33. The back of the scraper part 31 is fixed with an inner slider 34 that can slide radially along the inner sliding groove 33. A detachable spring part 35 is installed between the inner slider 34 and the reinforcing seat 32. There is an angle between the scraper part 31 and the functional plate 22 between 15° and 60°. Since the front end of the scraper part 31 acts on the inner layer of rubber strip during the coating process, there is a certain positional difference between the scraper part 31 and the main pressure roller 7 and the rubber roller. Therefore, the elastic force of the spring part 35 pushes the scraper part 31, so that the scraper part 31 is flexibly pressed on the lower layer of rubber strip, thereby improving the scraping effect of the overflowing glue.

[0050] like Figure 4 as well as Figure 6 As shown, since the scraper section 31 is in long-term contact with the rubber strip, although its translation can scrape the glue off the surface of the rubber roller, some glue is also easily left on its surface. Therefore, a glue-removing scraper 30 that can act on the surface of the scraper section 31 is provided on the functional plate 22. The functional plate 22 is also provided with a transmission structure for driving the glue-removing scraper 30 to move. The transmission structure includes a rotating block 23, an arc-shaped rail groove 24, a straight rail groove 25, a rotating inner arm 26, and a rotating sleeve arm 27. The rotating block 23 is rotatably connected to the surface of the functional plate 22. The arc-shaped rail groove 24 and the straight rail groove 25 are connected to the surface of the functional plate 22. All 5 are opened on the surface of the function plate 22, and the straight rail groove 25 is connected to the arc-shaped rail groove 24; the rotating inner arm 26 is fixed on the surface of the rotating block 23, and the rotating sleeve arm 27 is slidably sleeved on the outside of the rotating inner arm 26. The front end of the rotating sleeve arm 27 is fixed with a front assembly plate 29, and the surface of the front assembly plate 29 is provided with a slot. The front end of the adhesive removal scraper 30 is inserted into the slot, and the adhesive removal scraper 30 is detachable by bolts. The arc-shaped rail groove 24 is arc-shaped, the straight rail groove 25 is straight, and the rotating inner arm 26 is parallel to the scraper part 31.

[0051] The outer wall of the rotating sleeve arm 27 is fixed with a slider that can move along the arc-shaped rail groove 24 and the straight rail groove 25. That is, when the rotating block 23 rotates, it will drag the rotating inner arm 26 to rotate. When the rotating inner arm 26 rotates, it will drive the rotating sleeve arm 27 to rotate. Since the rotating sleeve arm 27 is connected to the grooves of the arc-shaped rail groove 24 and the straight rail groove 25 through the slider, when the rotating sleeve arm 27 rotates in the arc-shaped rail groove 24, the positions of the rotating sleeve arm 27 and the rotating inner arm 26 will not move relative to each other. When the slider moves from the arc-shaped rail groove 24 into the groove of the straight rail groove 25, The rotating sleeve arm 27 and the rotating inner arm 26 are slidably adjusted. At this time, the adhesive removal scraper 30 connected to the front end of the rotating sleeve arm 27 will contact the surface of the scraper section 31. The shape of the adhesive removal scraper 30 is not limited to the angle shown in the figure. It is sufficient to ensure that the front half of the adhesive removal scraper 30 can contact the surface of the scraper section 31 as much as possible when it enters the position of the straight track groove 25. The inner wall of the rotating sleeve arm 27 is fixedly provided with a limiting slider, and the outer wall of the rotating inner arm 26 is fixedly provided with a limiting arm groove 28 that matches the slider. By moving the adhesive removal scraper 30 on the scraper section 31, the residual adhesive can be scraped off from the scraper section 31.

[0052] like Figure 2 as well as Figure 8 As shown, a shaft assembly 71 is fixedly mounted on the shaft of the main pressure roller 7. A displacement inner hole 36 is provided at the end of the shaft assembly 71. A multi-faceted slider 37 slides radially within the groove of the displacement inner hole 36, and a top-mounted screw 38 is used to lock the position of the multi-faceted slider 37. A gear portion 39 is fixedly mounted on the top of the multi-faceted slider 37. A synchronous disc 231 is fixedly mounted on the end face of the rotating block 23. A transmission gear 232 meshes with the gear portion 39 on the ring surface of the synchronous disc 231. The multi-faceted slider 37 can slide within the multi-faceted hole of the displacement inner hole 36, and the top-mounted screw 38... The screw 38 is also adjusted accordingly. After the adjustment is completed, the top screw 38 can be locked with a nut. It is necessary to adjust so that the gear part 39 can mesh with the transmission gear block 232. When the main pressure roller 7 presses the rubber strip surface and rotates, it can drive the shaft assembly 71 to rotate, thereby driving the gear part 39 to drive the synchronous disk 231 to rotate, providing power for the movement of the adhesive removal scraper 30. The transmission gear block 232 and the gear part 39 can be non-standard inclined toothed engagement pair or non-standard concave-convex meshing to achieve transmission.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
