Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a blanking mechanism for a heat shrink machine. Background Technology

[0002] In new energy products, wire harnesses are an indispensable and crucial component, commonly used to achieve power connections between devices such as relay lines and control systems. During the manufacturing process, wire harnesses are fitted with sleeves, and then a heat-shrinking mechanism shrinks the sleeves to form a protective layer tightly adhering to the wire harness surface. However, in existing heat-shrinking mechanisms using tracked wire harness transport, a portion of the wire harness is exposed on the outside of the track. This portion of the wire harness is not subject to transport power, which may cause positional shifts during transport, making it difficult to accurately unload the wire harness after heat shrinking. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a blanking mechanism for a heat shrink machine, which can effectively suppress the positional displacement phenomenon during the heat shrinking process of the wire harness, so as to improve the blanking accuracy of the wire harness after heat shrinking.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a material feeding mechanism for a heat shrink machine, comprising...

[0005] The workbench is provided with a heat shrink station and a material unloading station in sequence; the heat shrink station is provided with a heat shrink channel for conveying products.

[0006] The material feeding assembly is located on the heat shrink station and symmetrically arranged on both sides of the heat shrink channel; each set of the material feeding assembly includes a material feeding base that can reciprocate along the product conveying direction, and the material feeding base is provided with a material feeding rod that can be lifted and moved.

[0007] When the material feeding rod is in its lowest position, its upper end is below the heat shrink channel; when the material feeding rod is in its highest position, its upper end is above the heat shrink channel.

[0008] The beneficial effects of this material feeding mechanism are as follows:

[0009] Material feeding components are installed on both sides of the heat shrink tunnel. These components move the exposed wire harness portions on both sides of the heat shrink tunnel synchronously during product (wire harness) transport, preventing positional shifts. Within the feeding components, the reciprocating movement of the feeding base drives the feeding rod to reciprocate along the product transport direction. The lifting and lowering of the feeding rod ensures that, at its highest position, it extends above the wire harness within the heat shrink tunnel. As the feeding rod moves along the product transport direction, it abuts against and pushes the exposed wire harness outside the heat shrink tunnel, ensuring synchronous movement between the wire harness portion outside and inside the tunnel, thus guaranteeing accurate placement of the wire harness at the unloading station. When the feeding rod is at its lowest position, it is below the wire harness within the heat shrink tunnel. At this point, the feeding rod returns to the entrance of the heat shrink tunnel to facilitate the movement of the next wire harness.

[0010] Furthermore, the feeding rod is arranged vertically, and a flexible sleeve is fitted on it to abut against the product. The flexible sleeve reduces rigid damage to the product.

[0011] Furthermore, the unloading station is equipped with a receiving platform for receiving products. The height of the receiving platform is lower than that of the heat shrink tunnel, and an inclined buffer platform is provided between the receiving platform and the heat shrink tunnel. The buffer platform can cushion the product unloading action.

[0012] Furthermore, the buffer platform includes an inclined plate body that gradually slopes from near the heat shrink tunnel towards the receiving platform. The inclined plate body is provided with a buffer bracket for the product to abut against, with the high end of the buffer bracket near the outlet of the heat shrink tunnel and the low end near the receiving platform. The buffer bracket guides the movement of the product during unloading.

[0013] Furthermore, the inclined plate body is provided with limiting slots that correspond one-to-one with the feeding components; the feeding rod can stop within the corresponding limiting slot. The limiting slots limit the movement range of the feeding rod, and since the limiting slots are set on the inclined plate body, when the feeding rod moves to the limiting slot, the product has entered the buffer support. That is, the pushing action of the feeding rod on the product can continue from the product in the heat shrink channel to the product moving to the buffer support.

[0014] Furthermore, at least one first cooling fan is installed on the buffer platform. Since the product moves along the buffer support, the first cooling fan installed on the buffer platform can provide air cooling to the product from below.

[0015] Furthermore, a cooling rack is provided above the buffer platform, and at least one second cooling fan is installed on the cooling rack. The second cooling fan can provide air cooling to the product from above.

[0016] Furthermore, the heat-shrinking station is equipped with an upper conveyor belt and a lower conveyor belt positioned opposite each other, forming a heat-shrinking channel for transporting the product. Each of the upper and lower conveyor belts contains a ceramic heating element. The cooperation of the upper and lower conveyor belts enables the product to be transported during the heat-shrinking process. During transport, the product is radiated and heated by the ceramic heating elements, allowing the sleeve to be heat-shrinked onto the wire harness. Using the upper and lower conveyor belts to transport the wire harnesses simultaneously improves efficiency and also increases the heat-shrinking time of the sleeve by the ceramic heating elements, ensuring a good heat-shrinking effect.

[0017] Furthermore, the workbench is provided with guide grooves that correspond one-to-one with the feeding components. The guide grooves are arranged along the product conveying direction to guide the movement of the feeding base.

[0018] Furthermore, the feeding bases of the two sets of feeding assemblies are connected to a linear module mounted on the workbench via a connecting plate. The linear module drives the two feeding bases to move synchronously via the connecting plate. Driving the two feeding assemblies synchronously via the linear module avoids skewing during product transfer. Attached Figure Description

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] Example

[0034] See appendix Figure 1-3 As shown, the present invention discloses a material feeding mechanism for a heat shrink machine, comprising a worktable 1 and a material feeding assembly 2. The worktable 1 is provided with a heat shrink station and a material feeding station in sequence. The heat shrink station is provided with a heat shrink channel 31 for conveying products. The material feeding assembly 2 is located on the heat shrink station and symmetrically arranged on both sides of the heat shrink channel 31. Each material feeding assembly 2 includes a material feeding base 21 that can reciprocate along the product conveying direction. The material feeding base 21 is provided with a material feeding rod 22 that can be raised and lowered. When the material feeding rod 22 is in the lowest position of movement, the upper end of the material feeding rod 22 is lower than the heat shrink channel 31. When the material feeding rod 22 is in the highest position of movement, the upper end of the material feeding rod 22 is higher than the heat shrink channel 31.

[0035] In the initial state, the feeding rod 22 is located at its lowest position and close to the entrance of the heat shrink channel 31. When the product 4 (wire harness) enters the heat shrink channel 31 from the entrance, both ends of the product 4 are exposed on both sides of the heat shrink channel 31. At this time, the feeding rods 22 of both sets of feeding components 2 are moved to the highest position, and then the feeding base 21 is driven to move towards the exit direction of the heat shrink channel 31. The feeding rods 22 of both sets of feeding components 2 can then abut against the product 4 exposed on both sides of the heat shrink channel 31 and push the product 4 towards the exit direction of the heat shrink channel 31. Since both ends of the product 4 can be pushed by the feeding components 2, the forces on both ends of the product 4 are balanced. Therefore, the product 4 will not deviate at an angle during the process of being conveyed along the heat shrink channel 31, thus ensuring that the product 4 can accurately fall into the unloading station.

[0036] To prevent rigid damage to the product surface caused by the feeding rod 22 during the feeding process, in some embodiments, the feeding rod 22 is arranged vertically and fitted with a flexible sleeve for abutting against the product 4. The flexible sleeve reduces rigid damage to the product 4.

[0037] In some embodiments, see Appendix Figure 2 As shown, an upper conveyor belt 32 and a lower conveyor belt 33 are arranged opposite each other at the heat shrink station, forming a heat shrink channel 31 for conveying the product 4 between the upper conveyor belt 32 and the lower conveyor belt 33; and ceramic heating elements are respectively installed in the upper conveyor belt 32 and the lower conveyor belt 33. The upper conveyor belt 32 and the lower conveyor belt 33 cooperate to realize the conveying of the product 4 in the heat shrinking process. At the same time, during the conveying process, the product 4 can be radiated and heated by the ceramic heating elements, so that the sleeve can be heat-shrinked onto the wire harness. The use of the upper conveyor belt 32 and the lower conveyor belt 33 to transport the product 4 can not only transport multiple products 4 at the same time, improving efficiency, but also increase the heat shrinking time of the sleeve by the ceramic heating elements to a certain extent, ensuring the heat shrinking effect.

[0038] In some embodiments, see Appendix Figure 1 As shown, the unloading station is equipped with a receiving platform 11 for receiving product 4. The height of the receiving platform 11 is lower than that of the heat shrink channel 31, and an inclined buffer platform 12 is provided between the receiving platform 11 and the heat shrink channel 31. The buffer platform 12 is provided with limiting slots 121 that correspond one-to-one with the feeding components 2, and the feeding rod 22 can stop in the corresponding limiting slot 121. The limiting slots 121 limit the movement range of the feeding rod 22. Since the limiting slots 121 are set on the buffer platform 12, when the feeding rod 22 moves to the limiting slot 121, product 4 has entered the buffer platform 12. That is to say, the pushing action of the feeding rod 22 on product 4 can continue from product 4 in the heat shrink channel 31 to product 4 moving to the buffer platform 12, so as to ensure that product 4 can smoothly enter the buffer platform 12. In addition, the inclined setting of the buffer platform 12 can utilize the weight of the product 4 to ensure that the product 4 enters the receiving platform 11.

[0039] Specifically, the buffer platform 12 includes an inclined plate body that gradually slopes from near the heat shrink tunnel 31 towards near the receiving platform 11. The inclined plate body is provided with a buffer bracket 122 for the product to abut. The high end of the buffer bracket 122 is close to the outlet of the heat shrink tunnel 31, and the low end is close to the receiving platform 11. The buffer bracket 122 is used to guide the dropping movement of the product 4.

[0040] Because product 4 reaches a high temperature after heat shrinking within the heat shrink channel 31, in some embodiments, see Appendix Figure 2-3As shown, at least one first cooling fan 5 is installed on the buffer platform 12. Since the product 4 moves along the buffer support 122, the first cooling fan 5 installed on the buffer platform 12 can provide air cooling for the product 4 from below. Furthermore, a cooling frame 6 fixed to the upper conveyor belt 32 is provided above the buffer platform 12. The cooling frame 6 is arranged parallel to the inclined plate body, and at least one second cooling fan 7 is installed on it. The second cooling fan 7 can provide air cooling for the product 4 from above.

[0041] In some embodiments, to ensure the synchronicity of the movement of the two feed levers 22, see Appendix Figure 4 As shown, the feeding base 21 of the two feeding components 2 is connected to the linear module 8 installed on the workbench 1 through the connecting plate 23. The linear module 8 drives the two feeding bases 21 to move synchronously through the connecting plate 23.

[0042] Furthermore, the workbench 1 is provided with guide grooves 13 that correspond one-to-one with the feeding components 2. The guide grooves 13 are arranged along the product conveying direction to guide the movement of the feeding base 21.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
