Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy heating plate assembly technology, and in particular to a bushing with simplified assembly. Background Technology

[0002] Alloy heating plates are high-efficiency heat conduction and heating elements with aluminum alloy as the base material. Through material properties and structural design, they achieve rapid heating, uniform heat dissipation, and precise temperature control, and are widely used in industrial heating, home appliance temperature control, and precision equipment.

[0003] Currently, traditional gluing machine bushings have flanges. The assembly method requires first installing the traditional bushings on both ends of the glue roller, then installing the side plates on the aluminum alloy heating plate, and finally assembling the wire springs to press on the bushings. Because the bushings are easy to rotate on the glue roller, when installing the side plates on the aluminum alloy heating plate, the position of the wire springs on the upper part of the traditional bushings is not easy to align with the grooves on the side plates, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the bushing easily rotating on the rubber roller and the difficulty in aligning the upper part of the bushing with the groove on the side plate during installation, which leads to low production efficiency. Therefore, this invention proposes a bushing with simplified assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bushing with simplified assembly, comprising:

[0007] An aluminum alloy heating plate, wherein multiple rubber rollers extend through both ends of the aluminum alloy heating plate;

[0008] Side plates, two side plates are provided, and each side of the two side plates has the same number of insertion holes as the number of rubber rollers;

[0009] A fixing component can be detachably installed on the side plate, which is used to facilitate quick assembly between the aluminum alloy heating plate and the side plate.

[0010] In one possible design, the fixing assembly includes a first wire spring, a second wire spring, and a plurality of glue applicator bushings equal in number to the number of insertion holes, the glue applicator bushings being detachable from the insertion holes.

[0011] In one possible design, positioning posts are fixedly installed next to the insertion holes on both sides of the side plate, baffles are fixedly installed next to the positioning posts on both sides of the side plate, and two baffles are symmetrically fixedly installed above the middle insertion hole on the side plate.

[0012] In one possible design, the inner diameter of the glue applicator bushing is adapted to the outer diameter of the glue roller, and the outer diameter of the glue applicator bushing is matched with the inner diameter of the insertion hole.

[0013] In one possible design, the coil spring is fitted outside the positioning post, one end of the coil spring abuts against the baffle, the other end of the coil spring abuts against the top of the side gluing machine bushing, and the coil spring can be disengaged and snapped into the two baffles, with the middle section of the coil spring abutting against the top of the middle gluing machine bushing.

[0014] In one possible design, the two side plates are respectively mounted on both sides of the aluminum alloy heating plate, and the diameter of the rubber roller is smaller than the inner diameter of the insertion hole.

[0015] In this application, upon initial use, first align one side plate with one side of the aluminum alloy heating plate, and align the end of the rubber roller on one side with the insertion hole on the side plate. Then, gently push the side plate to insert the end of the rubber roller into the insertion hole. During insertion, avoid collision between the rubber roller and the inner wall of the insertion hole. Next, insert different sized glue applicator bushings one by one into the corresponding insertion holes. During this process, the inner diameter of the glue applicator bushing fits outside the rubber roller, while the outer diameter of the glue applicator bushing inserts into the insertion hole. Because the inner and outer diameters of the glue applicator bushing match the inner and outer diameters of the rubber roller and the insertion hole, the insertion process is smooth and... This avoids situations where the installation is too loose or too tight. Then, insert the wire spring into the outside of the positioning post, and place one end of the wire spring against the top of the side glue applicator bushing. Then push the other end of the wire spring to make it abut against the corresponding baffle to form a pre-tightening force, thereby completing the fixation of the side glue applicator bushing. Then, first insert one end of the wire spring into the slot of one of the baffles, and press one end of the wire spring (at this time, the middle section of the wire spring abuts against the top of the glue applicator bushing) to make it bend and insert it into the slot of another baffle to form a pre-tightening force, thereby completing the fixation of the middle glue applicator bushing.

[0016] This utility model has the following beneficial effects:

[0017] This invention eliminates the need for a flanged bushing by setting a fixed component. Instead, it uses a sequence where the side plate is first installed on the rubber roller and aluminum alloy heating plate, then the bushing is installed, and finally the wire spring is assembled. This effectively avoids the assembly misalignment problem caused by the rotation of the bushing, and allows the wire spring to be accurately aligned with the side plate groove, significantly improving assembly efficiency and production convenience.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-4 A bushing, comprising:

[0026] It consists of an aluminum alloy heating plate 1, two side plates 3 and a fixing component. The aluminum alloy heating plate 1 is the core component, and multiple rubber rollers 2 extend through both ends of it. The assembly between the aluminum alloy heating plate 1 and the side plates 3 is achieved by installing the two side plates 3 on both sides of the aluminum alloy heating plate 1 and quickly connecting them to the aluminum alloy heating plate 1 through the fixing component.

[0027] Each side plate 3 has the same number of insertion holes 4 as the rubber roller 2. The layout of these insertion holes 4 corresponds one-to-one with the position of the rubber roller 2 to ensure the accuracy of assembly. The design of the insertion holes 4 takes into account the diameter of the rubber roller 2, making it slightly larger than the diameter of the rubber roller 2 to facilitate the smooth insertion of the rubber roller 2.

[0028] The fixing component is the key to the quick assembly of the bushing. It includes a first wire spring 9, a second wire spring 10, and multiple glue applicator bushings 5, which are the same number as the number of insertion holes 4. Each glue applicator bushing 5 can be detachably inserted into the corresponding insertion hole 4. Its inner diameter is adapted to the outer diameter of the glue roller 2, and its outer diameter matches the inner diameter of the insertion hole 4, ensuring the stability after assembly.

[0029] A wire spring 9 is sleeved on the outside of the positioning posts 6 on both sides of the side plate 3. One end abuts against the baffle 7, and the other end abuts against the top of the side glue machine bushing 5. The preload of the wire spring 9 is used to fix the side glue machine bushing 5.

[0030] The second spring 10 can be disengaged and locked onto the two retainers 8. Its middle section abuts against the top of the middle glue machine bushing 5, forming a pre-tightening force to ensure the stable assembly of the middle glue machine bushing 5.

[0031] This application can be used in the field of bushing technology for simplifying assembly, or in other fields applicable to this application.

At the same time, baffles 7 are fixedly provided on both sides of the side plate 3 next to the positioning posts 6 for limiting the position of the first coil spring 9. In addition, two baffles 8 are symmetrically fixedly provided on the side plate 3 above the middle insertion hole 4 for installing and fixing the second coil spring 10.
