Description

Technical Field

[0001] This application relates to the field of safety switches, and more particularly to a safety switch for the production of plastic rolls. Background Technology

[0002] A safety switch is a switch that prevents personnel from entering a hazardous area until all safety conditions are met. There are various types, including latch switches, safety magnetic switches, safety door lock switches, safety pull-cord switches, emergency stop buttons, hinged interlock switches, safety enable switches, safety limit switches, and explosion-proof switches. PVC roll flooring is generally produced using a calendering process. It contains less filler and more plasticizer than PVC floor tiles. PVC is typically plasticized using a four-roll calender, resulting in a smooth and clean surface after calendering. After cooling, the edges are trimmed and the rolls are rolled into the final product. The specifications of roll flooring vary from country to country. Soft PVC roll flooring is relatively soft, has a certain degree of elasticity, and is comfortable underfoot.

[0003] In the actual production process of plastic rolls, the rolls need to be wound up. During the winding process, the winding equipment is equipped with a safety switch to ensure the safety of the winding equipment. However, the existing safety switches are directly fixed to the winding equipment with bolts. After the bolts are installed, the safety switches cannot be adjusted. The safety switches on the winding equipment are mainly pull rope switches. When installing pull rope switches, the direction of the switch needs to be adjusted with the pull rope. After the bolts are fixed, it is inconvenient to adjust the direction of the installed switch. Utility Model Content

[0004] To address the problem of inconvenient adjustment of existing safety switches, this application provides a safety switch for plastic roll production.

[0005] The safety switch for plastic roll production provided in this application adopts the following technical solution:

[0006] A safety switch for the production of plastic rolls includes a frame of a winding equipment and a switch mechanism mounted on the frame. A mounting mechanism is installed on one outer wall of the frame, and the switch mechanism is mounted on the mounting mechanism. The mounting mechanism includes a mounting seat rotatably connected to the frame, and mounting components are installed on both outer walls of the mounting seat. A mounting groove is formed on one outer wall of the mounting seat, and two symmetrically arranged connecting grooves are formed on both inner walls of the mounting groove.

[0007] By adopting the above technical solution, the frame facilitates the installation of the mounting mechanism, which in turn facilitates the installation of the switch mechanism. The mounting mechanism can rotate on the frame, and when it rotates, it is convenient to make appropriate adjustments to the switch mechanism, thus facilitating the installation and adjustment of the auxiliary switch mechanism.

[0008] Preferably, a worm gear is rotatably connected to the outer wall of the other side of the frame, and one end of the drive shaft of the worm gear is fixedly connected to the mounting base.

[0009] By adopting the above technical solution, the installation of the switch mechanism is facilitated by the mounting base in the installation component. The cooperation between the mounting slot and the connecting slot facilitates the quick positioning and installation of the auxiliary switch mechanism. When the worm gear rotates, the mounting base can be rotated and adjusted.

[0010] Preferably, a worm gear is rotatably connected to one side of the outer wall of the frame, and the worm gear and the worm wheel mesh with each other. A rotating disk is fixedly connected to one end of the transmission shaft of the worm gear.

[0011] By adopting the above technical solution, the rotation of the rotating disk directly drives the worm gear to rotate, the rotation of the worm gear directly drives the worm wheel to rotate, and the rotation of the worm wheel directly drives the mounting base to rotate, thereby adjusting the switching mechanism.

[0012] Preferably, the switching mechanism includes a switch body, and a pull rope is connected to the top outer wall of the switch body. Two symmetrically arranged connecting seats are fixedly connected to both outer walls of the switch body, and a limit groove is formed on one outer wall of each of the four connecting seats.

[0013] By adopting the above technical solution, the cooperation between the switch body and the pull rope facilitates the auxiliary winding equipment, and the cooperation between the connecting seat and the limiting groove facilitates the quick installation of the auxiliary switch body.

[0014] Preferably, the switch body is snapped into the mounting groove, and the connector is snapped into the connecting groove.

[0015] By adopting the above technical solution, the connecting groove on the mounting slot facilitates the installation and positioning of the auxiliary switch body.

[0016] Preferably, the mounting assembly includes a mounting box fixedly connected to the mounting base, and a sliding seat is slidably connected to the inner wall of the mounting box. Two openings are opened on one outer wall of the mounting box, and limit blocks are slidably connected to the inner walls of the two openings. The two limit blocks are fixedly connected to the sliding seat, and the limit blocks are slidably connected to the connecting groove through the mounting base.

[0017] By adopting the above technical solution, the limit block can be easily slidably installed by setting the installation box. The switch body can be installed when the limit block is inserted into the limit groove in the connector.

[0018] Preferably, both inner walls of the mounting box are rotatably connected to screws, and the same worm gear is fixedly connected between the two screws. The outer walls of the two screws are screwed with threaded sleeves, and the outer walls of the two threaded sleeves are rotatably connected to connecting plates. One end of each of the two connecting plates is rotatably connected to a sliding seat.

[0019] By adopting the above technical solution, the two screws can be installed conveniently by setting the worm gear two. When the worm gear two rotates, it directly drives the two screws to rotate synchronously. When the two screws rotate, it directly drives the two threaded sleeves to move towards or away from each other. When the two threaded sleeves move towards each other, the sliding seat is pushed out directly through the connecting plate. Conversely, when the two threaded sleeves move away from each other, the sliding seat is pulled into the mounting box directly through the connecting plate.

[0020] Preferably, a second worm gear is rotatably connected to one inner wall of the mounting box, and the second worm gear and the second worm wheel mesh with each other. One end of the drive shaft of the second worm gear is fixedly connected to a rotating part.

[0021] By adopting the above technical solution, the rotating part allows for easy manual rotation of the second worm gear. When the second worm gear rotates, it directly drives the second worm wheel to rotate, thereby facilitating the adjustment of the position of the limit block through the cooperation of the threaded sleeve, connecting plate, and sliding seat.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application provides an installation mechanism on the frame, with a worm gear and a worm wheel on the installation mechanism to facilitate rotation and adjustment of the installation mechanism. The switch mechanism is also conveniently installed on the installation mechanism, thereby facilitating the adjustment of the switch mechanism on the winding equipment and solving the problem of inconvenient adjustment of the safety switch on existing winding equipment.

[0024] 2. This application provides two mounting components in the mounting mechanism, which facilitates the quick installation of the switch mechanism. The two adjustable limit blocks in the mounting components facilitate fixing the switch body to the mounting base via the connecting seat, thereby improving the efficiency of the switch body's assembly and disassembly.

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a safety switch for the production of plastic rolls.

[0032] Reference Figure 1-3 A safety switch for the production of plastic rolls includes a frame 1 of a winding equipment and a switch mechanism 3 mounted on the frame 1. A mounting mechanism 2 is mounted on one outer wall of the frame 1, and the switch mechanism 3 is mounted on the mounting mechanism 2.

[0033] Reference Figure 2-3 The mounting mechanism 2 includes a mounting base 11 rotatably connected to the frame 1, and mounting components 12 are installed on both outer walls of the mounting base 11. A mounting groove 13 is opened on one outer wall of the mounting base 11, and two symmetrically arranged connecting grooves 14 are opened on both inner walls of the mounting groove 13. The frame 1 facilitates the installation of the mounting mechanism 2, and the mounting mechanism 2 facilitates the installation of the switch mechanism 3. The mounting mechanism 2 can rotate on the frame 1. When the mounting mechanism 2 rotates, it is convenient to make appropriate adjustments to the switch mechanism 3, which facilitates the installation and adjustment of the switch mechanism 3.

[0034] Reference Figure 1-3 A worm gear 5 is rotatably connected to the outer wall of the other side of the frame 1, and one end of the drive shaft of the worm gear 5 is fixedly connected to the mounting base 11. The mounting base 11 in the mounting assembly 12 facilitates the installation of the switch mechanism 3. The cooperation between the mounting groove 13 and the connecting groove 14 facilitates the quick positioning and installation of the auxiliary switch mechanism 3. When the worm gear 5 rotates, it is convenient to rotate and adjust the mounting base 11. A worm 6 is rotatably connected to one side of the outer wall of the frame 1, and the worm 6 and the worm gear 5 mesh with each other. One end of the drive shaft of the worm 6 is fixedly connected to a rotating disk 4. The rotation of the rotating disk 4 directly drives the worm 6 to rotate. When the worm 6 rotates, it directly drives the worm gear 5 to rotate. When the worm gear 5 rotates, it directly drives the mounting base 11 to rotate, thereby adjusting the switch mechanism 3.

[0035] Reference Figure 3-4The mounting assembly 12 includes a mounting box 15 fixedly connected to the mounting base 11, and a sliding seat 19 slidably connected to the inner wall of the mounting box 15. Two openings are opened on one side of the outer wall of the mounting box 15, and limit blocks 20 are slidably connected to the inner walls of the two openings. The two limit blocks 20 are fixedly connected to the sliding seat 19. The limit blocks 20 pass through the mounting base 11 and are slidably connected to the connecting groove 14. Screws 16 are rotatably connected to both sides of the inner wall of the mounting box 15, and the same worm gear 22 is fixedly connected between the two screws 16. Threaded sleeves 17 are screwed to the outer walls of the two screws 16, and connecting plates 18 are rotatably connected to the outer walls of the two threaded sleeves 17. One end of the two connecting plates 18 is rotatably connected to the sliding seat 19. A worm gear 21 is rotatably connected to one side of the inner wall of the mounting box 15, and the worm gear 21 and the worm wheel 22 mesh with each other. A rotating part 23 is fixedly connected to one end of the drive shaft of the worm gear 21.

[0036] In use, the mounting box 15 facilitates the sliding installation of the limit block 20. When the limit block 20 is inserted into the limit groove 9 in the connecting seat 8, the switch body 7 can be installed. The worm gear 22 facilitates the installation of the two screws 16. When the worm gear 22 rotates, it directly drives the two screws 16 to rotate synchronously. When the two screws 16 rotate, they directly drive the two threaded sleeves 17 to move towards or away from each other. When the two threaded sleeves 17 move towards each other, they directly push the sliding seat 19 to extend through the connecting plate 18. Conversely, when the two threaded sleeves 17 move away from each other, they directly pull the sliding seat 19 back into the mounting box 15 through the connecting plate 18. The rotating part 23 facilitates the manual rotation of the worm gear 21. When the worm gear 21 rotates, it directly drives the worm gear 22 to rotate, thereby facilitating the adjustment of the position of the limit block 20 through the cooperation of the threaded sleeves 17, the connecting plate 18, and the sliding seat 19.

[0037] Reference Figure 2-3 The switching mechanism 3 includes a switch body 7, and a pull rope 10 is connected to the top outer wall of the switch body 7. Two symmetrically arranged connecting seats 8 are fixedly connected to the outer walls of both sides of the switch body 7. A limit groove 9 is opened on one side of the outer wall of each of the four connecting seats 8. The cooperation between the switch body 7 and the pull rope 10 facilitates the auxiliary winding equipment. The cooperation between the connecting seats 8 and the limit groove 9 facilitates the quick installation of the auxiliary switch body 7. The switch body 7 is snapped into the mounting groove 13, and the connecting seats 8 are snapped into the connecting groove 14. The connecting groove 14 on the mounting groove 13 facilitates the installation and positioning of the auxiliary switch body 7.

[0038] The implementation principle of a safety switch for plastic roll production according to an embodiment of this application is as follows: In use, the switch body 7 is first installed on the mounting mechanism 2. During installation, the switch body 7 is placed in the mounting groove 13, and the four connecting seats 8 are respectively inserted into the connecting grooves 14. Then, the rotating part 23 is rotated. When the rotating part 23 rotates, it directly drives the worm wheel 22 to rotate via the worm gear 21. When the worm wheel 22 rotates, it directly drives the two screws 16 to rotate. When the two screws 16 rotate, they directly drive the two threaded sleeves 17 to move towards or away from each other. When the two threaded sleeves 17 move towards each other, they directly... The sliding seat 19 is moved by the connecting plate 18. When the sliding seat 19 moves, it directly pushes the two limit blocks 20 into the limit grooves 9 on the connecting seat 8, so as to fix the switch body 7 in the mounting groove 13. Then the pull rope 10 is installed on the switch body 7. When the switch body 7 needs to be adjusted, the rotating disk 4 is rotated first. When the rotating disk 4 rotates, it directly drives the worm gear 6 to rotate. When the worm gear 6 rotates, it directly drives the worm wheel 5 to rotate. When the worm wheel 5 rotates, it directly adjusts the angle of the mounting seat 11, so as to facilitate the adjustment of the switch body 7 with the pull rope 10.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
