A wiper silicon rubber strip heating and conveying device

Abstract

This utility model relates to the field of windshield wiper silicone strip heating and conveying technology, and discloses a windshield wiper silicone strip heating and conveying device, including a conveyor belt and a processing machine set on the conveyor belt. The processing machine is fixedly installed with a feed port, and a heating machine is set at the other end of the conveyor belt. Both ends of the heating machine are provided with conveying ports. With the cooperation of a telescopic cylinder, a support rod, a force rod, a second slide groove, a diaphragm plate, a servo motor, a second bidirectional threaded rod, and a connecting block, the diaphragm plate is displaced out of the mold. Since the silicone has initially solidified, it will not flow out from the vent hole. At this time, the air circulation can be increased through the vent hole, thereby accelerating the solidification of the silicone sidewall and indirectly improving the conveying efficiency of the silicone strip. It can also play a role in rapid demolding. Since the silicone has not yet been plasticized, the quality of the silicone strip will not be affected during demolding.

Description

Technical Field

[0001] This utility model relates to the field of windshield wiper silicone strip heating and conveying technology, specifically a windshield wiper silicone strip heating and conveying device. Background Technology

[0002] Silicone rubber strips, as a high-performance sealing and connecting material, are widely used in various industries. They are made from silicone (also known as silicone rubber) through a special process, possessing excellent physicochemical properties and wide applicability. Silicone, as a polymer compound, is mainly composed of an alternating skeleton of silicon and oxygen atoms, linked to silicon atoms by organic groups (such as methyl and vinyl groups), giving it unique properties.

[0003] Existing wiper silicone strip heating and conveying devices involve pouring processed silicone into a mold and then conveying it into a heating machine for heating. However, the mold obstructs the heating process, resulting in low heating efficiency and poor air circulation, which in turn leads to low conveying efficiency. Furthermore, some silicone inevitably remains on the mold during demolding, affecting the molding quality of the silicone strip. Utility Model Content

[0004] The purpose of this utility model is to provide a heating and conveying device for windshield wiper silicone strips, in order to solve the problems mentioned in the background art, which involves pouring processed silicone into a mold and then conveying it into a heating machine for heating. However, the heating efficiency is low due to the obstruction of the mold, and air circulation is not possible, resulting in low conveying efficiency. Furthermore, some silicone inevitably remains on the mold when the heated and molded silicone is demolded, which affects the molding quality of the silicone strip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a conveyor belt and a processing machine mounted on the conveyor belt. A feed inlet is fixedly installed on the processing machine. A heater is installed at the other end of the conveyor belt. Both ends of the heater have conveying ports. A conveying assembly for pouring the processed silicone liquid into a mold is installed at the lower end of the processing machine. A demolding assembly for easy demolding is installed on the conveyor belt. A first chamber is opened on the heater. A lifting assembly for accelerating heat conduction and demolding the demolding assembly is installed in the first chamber. A displacement assembly is installed on the lifting assembly.

[0006] Preferably, the conveying assembly includes a fixed block fixedly installed at the lower end of the processing machine, a drive motor fixedly installed on the side wall of the fixed block, a fixed rod fixedly installed at the lower end of the processing machine, an installation groove and a first sliding groove on the fixed rod, a first bidirectional threaded rod rotatably installed on the installation groove, the output end of the drive motor being fixedly connected to the first bidirectional threaded rod, a connecting block being threadedly connected to the axial side wall of the first bidirectional threaded rod, the connecting block being slidably connected to the first sliding groove, and a telescopic tube being provided between the lower end of the processing machine and the connecting block.

[0007] Preferably, the demolding assembly includes a plurality of molds disposed on a conveyor belt, each of the molds having a second chamber and two slots, the sidewalls of the molds having a plurality of ventilation holes, and diaphragm plates being inserted and installed in the two slots.

[0008] Preferably, the lifting assembly includes a servo motor fixedly installed in the first chamber, two limiting blocks fixedly installed in the first chamber, a second bidirectional threaded rod rotatably installed on the two limiting blocks, the output end of the servo motor fixedly connected to the second bidirectional threaded rod, a connecting block threadedly connected to the axial side wall of the second bidirectional threaded rod, and two limiting rods fixedly installed on the side frame of the conveyor belt, each of the two limiting rods having a second sliding groove.

[0009] Preferably, the displacement assembly includes a telescopic cylinder fixedly installed on the side wall of the connecting block, a support rod fixedly installed at the telescopic end of the telescopic cylinder, and two force-bearing rods fixedly installed on the side wall of the support rod.

[0010] Preferably, the distance between the two force-bearing rods is consistent with the size of the mold.

[0011] Preferably, the force-bearing rod corresponds to the second sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. With the cooperation of the telescopic cylinder, support rod, force rod, second slide groove, diaphragm plate, servo motor, second bidirectional threaded rod and connecting block, the diaphragm plate is displaced out of the mold. Since the silicone has initially solidified, it will not flow out from the vent hole. At this time, the air circulation can be increased through the vent hole, thereby accelerating the solidification of the silicone side wall, indirectly improving the conveying efficiency of the silicone strip, and also playing a role in rapid demolding. Since the silicone has not yet been plasticized, the quality of the silicone strip will not be affected during demolding.

[0013] 2. The processed silicone is conveyed through a telescopic tube to the mold. With the cooperation of the drive motor, the first bidirectional threaded rod, the connecting block and the first slide groove, the mold is injected. The mold is then conveyed to the heating machine by the conveyor belt to heat the silicone on the mold. The surface of the diaphragm plate on the mold is coated with a release agent to quickly demold, thereby preventing the silicone from sticking to the mold after heating, which would affect the quality of the silicone strip.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1 - Figure 4A heating and conveying device for silicone wiper strips includes a conveyor belt 1 and a processing machine 11 mounted on the conveyor belt 1. A feed inlet 12 is fixedly installed on the processing machine 11. A heating machine 13 is mounted at the other end of the conveyor belt 1. The heating method of the heating machine 13 is existing technology and will not be described in detail here. Both ends of the heating machine 13 have conveying ports 14. A conveying component 2 for pouring processed silicone liquid into a mold is mounted at the lower end of the processing machine 11. A demolding component 3 for easy demolding is mounted on the conveyor belt 1. A first chamber 41 is mounted on the heating machine 13. A lifting component 4 for demolding the demolding component 3 and accelerating heat conduction is mounted on the first chamber 41. A displacement component 5 is mounted on the lifting component 4. The displacement component 5, in conjunction with the lifting component 4, can demold the demolding component 3, thereby accelerating the heating efficiency of the silicone strip and indirectly improving the conveying efficiency of the silicone strip.

[0018] The conveying assembly 2 includes a fixed block 21 fixedly installed at the lower end of the processing machine 11. A drive motor 22 is fixedly installed on the side wall of the fixed block 21. A fixed rod 23 is fixedly installed at the lower end of the processing machine 11. The fixed rod 23 has an installation groove 24 and a first sliding groove 25. A first bidirectional threaded rod 26 is rotatably installed on the installation groove 24. The output end of the drive motor 22 is fixedly connected to the first bidirectional threaded rod 26. A connecting block 27 is threadedly connected to the axial side wall of the first bidirectional threaded rod 26. The connecting block 27 is slidably connected to the first sliding groove 25. A telescopic tube 28 is provided between the lower end of the processing machine 11 and the connecting block 27. The telescopic tube 28 is telescopic and can extend and retract with the displacement of the connecting block 27.

[0019] The demolding assembly 3 includes several molds 31 set on the conveyor belt 1. Each mold 31 has a second chamber 32 and two slots 34. Several ventilation holes 33 are opened on the side wall of the mold 31. A diaphragm plate 35 is inserted and installed in the two slots 34. The side wall of the diaphragm plate 35 is coated with a demolding agent, which enables the demolding operation to be carried out quickly.

[0020] In this embodiment: the processed silicone is conveyed through the telescopic tube 28 to the mold 31. At this time, the drive motor 22 is started, and the output end of the drive motor 22 drives the first bidirectional threaded rod 26 to rotate. Since the connecting block 27 and the first bidirectional threaded rod 26 are threadedly connected and the connecting block 27 and the first slide groove 25 are slidably connected, the first slide groove 25 restricts the rotation of the connecting block 27. This causes the connecting block 27 and the telescopic tube 28 to move along the first slide groove 25, thereby injecting the silicone into each mold 31. Subsequently, the mold 31 can be conveyed to the heating machine 13 by the conveyor belt 1, thereby heating the silicone on the mold 31. The surface of the diaphragm plate 35 on the mold 31 is coated with a release agent to quickly demold, thereby preventing the silicone from sticking to the mold 31 after heating, thus affecting the quality of the silicone strip.

[0021] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 5 and Figure 6 The lifting assembly 4 includes a servo motor 42 fixedly installed in the first chamber 41. Two limit blocks 43 are fixedly installed in the first chamber 41. A second bidirectional threaded rod 44 is rotatably installed on the two limit blocks 43. The output end of the servo motor 42 is fixedly connected to the second bidirectional threaded rod 44. A connecting block 45 is threadedly connected to the axial side wall of the second bidirectional threaded rod 44. Two limit rods 46 are fixedly installed on the side frame of the conveyor belt 1. A second sliding groove 47 is opened on each of the two limit rods 46.

[0022] The displacement assembly 5 includes a telescopic cylinder 51 fixedly installed on the side wall of the connecting block 45. A support rod 52 is fixedly installed on the telescopic end of the telescopic cylinder 51, and two force-bearing rods 53 are fixedly installed on the side wall of the support rod 52.

[0023] The distance between the two force rods 53 is consistent with the size of the mold 31. The force rods 53 can drive the lugs at both ends of the diaphragm plate 35, thereby moving the diaphragm plate 35 out of the mold 31. At this time, the molding speed of the silicone strip is accelerated through the vent hole 33.

[0024] The force-bearing rod 53 corresponds to the second slide groove 47. By inserting the force-bearing rod 53 into the second slide groove 47, the force-bearing rod 53 is limited, so that the force-bearing rod 53 can perform lifting and lowering operations.

[0025] In this embodiment: The mold 31 then enters the heating machine 13 via the conveyor belt 1. Because the lifting assembly 4 is located in the middle of the heating machine 13, when the mold 31 moves to the position of the lifting assembly 4, the silicone has already formed a basic solidification and there will be no flowability. At this time, the telescopic cylinder 51 is activated, causing the telescopic end of the telescopic cylinder 51 to drive the support rod 52 and the two force rods 53 forward until the two force rods 53 move into the second slide groove 47. At this time, the two force rods 53 are just located at the lower end of the two lugs of the diaphragm plate 35. Then, the servo motor 42 is activated, causing the output end of the servo motor 42 to drive the second bidirectional threaded rod 44 to rotate. Because at this time, the two force rods 53 are located at the lower end of the two lugs of the diaphragm plate 35. The force bar 53 located in the second slide groove 47 serves to restrict the rotation of the force bar 53. At this time, it drives the connecting block 45, telescopic cylinder 51, support rod 52 and the two force bars 53 to move upward. At this time, the diaphragm plate 35 is displaced out of the mold 31. Since the silicone has initially solidified, it will not flow out from the vent hole 33. At this time, the air circulation through the vent hole 33 can be increased, thereby accelerating the solidification of the silicone sidewall, indirectly improving the conveying efficiency of the silicone strip, and also playing a role in rapid demolding. Then, the diaphragm plate 35 is sent to the conveyor belt 1 through the lifting component 4 and the displacement component 5, and is conveyed out through the conveyor belt 1 to work on the next mold 31.
