Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and in particular to a bonding device for rubber parts. Background Technology

[0002] Currently, there are two methods for bonding rubber products: one is to prepare preforms of two rubber bonding parts using raw materials, and then vulcanize them together in a molding die at a certain vulcanization temperature to form an interfacial bond between the rubber bodies; the other method is to first prepare two vulcanized rubber bonding parts, then grind the bonding area, apply adhesive, and allow it to cure to form an interfacial adhesive bond.

[0003] Related technology can be found in Chinese patent application CN111531423A, which discloses a pre-treatment process for bonding rubber parts. The process includes a base plate, a positioning device, and a grinding device. The base plate has evenly distributed mounting holes, and a positioning device is installed at the center of the upper part of the base plate. A grinding device is positioned above the positioning device and mounted on the base plate. This pre-treatment process for bonding rubber parts solves the problems of existing equipment failing to quickly and firmly fix and tighten rubber parts during grinding, leading to displacement and shaking during subsequent processing. This results in poor bonding of the processed rubber parts, affecting the adhesion between them. Furthermore, existing equipment suffers from poor and uneven grinding, resulting in poor adhesion between the ground rubber parts, making them prone to cracking and affecting their long-term use.

[0004] Regarding the aforementioned technologies, the rubber bonding pretreatment process involves grinding the bonding area of ​​the rubber parts. After grinding, the operator aligns the bonding areas of the two rubber parts and bonds them together. However, due to the different pressing methods and pressing points used by the operator, the bonding area of ​​the rubber parts is subjected to uneven force, resulting in different bonding effects and poor bonding stability.

[0027] This application discloses an adhesive device for rubber parts. Example

[0028] Reference Figure 1 A bonding device for rubber parts includes a pretreatment component 1 and a bonding component 2. The bonding component 2 is used to bond the rubber parts treated by the pretreatment component 1. The pretreatment component 1 includes a processing device 11, a base 12, a second connecting plate 15, two vertical plates 13, and a first connecting plate 14. The processing device 11 is an angle grinder used to pretreat the bonding area of ​​the rubber parts. The base 12 is horizontally arranged. The two vertical plates 13 are respectively fixedly connected to both sides of the base 12 along the width direction, and the base 12 supports the two vertical plates 13. The vertical plates 13 have a first lifting port 131, which is arranged vertically. The first connecting plate 14 is located on the side of the two vertical plates 13 that are close to each other, and the first connecting plate 14 is slidably connected to the vertical plates 13 along the vertical direction. A first fixing bolt 132 is provided between the first connecting plate 14 and the vertical plate 13. The first fixing bolt 132 passes through the first lifting port 131 and is threadedly connected to the first connecting plate 14. Rotating the first fixing bolt 132 makes the vertical plate 13 fit tightly with the first connecting plate 14.

[0029] Reference Figure 1 The second connecting plate 15 is located between the first connecting plates 14 and is arranged vertically. A second fixing bolt 152 is provided between the second connecting plate 15 and the angle grinder. The second connecting plate 15 has a second lifting port 151 opened vertically. The second fixing bolt 152 passes through the second lifting port 151 and is threadedly connected to the angle grinder. Rotating the second fixing bolt 152 makes the angle grinder rise and fall along the length direction of the second lifting port 151. Rotating the second fixing bolt 152 in the opposite direction makes the angle grinder fit tightly with the second connecting plate 15, which can further adjust the height of the angle grinder and improve the convenience of rubber part pretreatment.

[0030] Reference Figure 1 and Figure 2The bonding component 2 includes a rectangular block 21, a rectangular plate 23, and a push rod 25. A cavity 22 is provided at the upper end of the rectangular block 21. The rectangular plate 23 is located in the cavity 22 and is arranged vertically. The rectangular plate 23 can slide along the length direction of the rectangular block 21. The rectangular plate 23 is attached to both sides of the rectangular block 21 along the width direction. A first opening 24 is provided along the length direction of the rectangular block 21. One end of the push rod 25 passes through the first opening 24 and is connected to the rectangular plate 23. The first opening 24 is located at the center of one side of the rectangular block 21 along the length direction. The push rod 25 drives the rectangular plate 23 to move and squeeze the rubber parts, which helps to improve the bonding degree between the rubber parts and improves the bonding stability of the rubber parts.

The nut 26 is directly opposite the first through-hole 24. The threaded rod 251 is threadedly connected to the nut 26. The nut 26 positions the threaded rod 251. The threaded rod 251 passes through the first through-hole 24 and is rotatably connected to the rectangular plate 23. By rotating the threaded rod 251, the threaded rod 251 pushes the rectangular plate 23 to compress the rubber part. The nut 26 is used to position the threaded rod 251, so that the rectangular plate 23 and the rubber part fit tightly together, which improves the stability of the rubber part's adhesion.

[0032] Reference Figure 1 and Figure 2 Two guide rods 28 are fixed on the side of the rectangular plate 23 near the threaded rod 251. The guide rods 28 are horizontally arranged along the length of the threaded rod 251. The two guide rods 28 are symmetrically arranged along the width of the rectangular block 21 with the threaded rod 251 as the center. The guide rods 28 pass through the rectangular block 21 and extend to the outside of the rectangular block 21. The guide rods 28 guide the movement of the rectangular plate 23, which helps to reduce the probability of the rectangular plate 23 tilting during movement and improves the stability of the rectangular plate 23 movement. A second opening 27 is opened at the lower end of the rectangular block 21. The second opening 27 is arranged vertically and is used to discharge air between the two rubber parts, which improves the stability of the rubber parts adhesion.

The two rubber parts are arranged along the length of the rectangular block 21 and are attached to the rectangular block 21. Adhesive is applied to the side of the two rubber parts that are close to each other. The threaded rod 251 is rotated, and the threaded rod 251 pushes the rectangular plate 23 to squeeze the rubber parts. The nut 26 is used to position the threaded rod 251 so that the rectangular plate 23 is tightly attached to the rubber parts. The guide rod 28 is used to guide the movement of the rectangular plate 23. The second opening 27 is used to discharge the air between the two rubber parts. By bonding the rubber parts with this device, the probability of poor bonding effect caused by manual bonding is reduced, and the stability of the rubber bonding is improved.
