Description

Technical Field

[0001] This application relates to the field of heat insulation cover processing technology, and in particular to an automated production line for heat insulation cover edge wrapping processing. Background Technology

[0002] In the field of mechanical processing and manufacturing, with the continuous development of industrial production, the requirements for processing efficiency and quality of various parts are increasing. Heat shields, as an important mechanical component, are widely used in many fields such as automobiles and aerospace. Their function is to reduce heat transfer and protect surrounding equipment and personnel. Efficient and precise heat shield processing technology is of paramount importance for improving product performance and production efficiency.

[0003] Currently, in the traditional heat insulation cover edging process, a dual-station loading mechanism is typically used to improve production line flexibility and facilitate intelligent scheduling and rapid switching of materials of different specifications. Currently, dual-station loading mechanisms in related technologies generally employ a one-to-one configuration of lifting drive components and two material bins. The two material bins move horizontally and are positioned at the loading station, with the corresponding lifting drive components pushing the material piles on the bins. A robotic arm then grasps the top layer of material from the pile.

[0004] However, in the processing of workpieces such as automotive parts where product consistency requirements are high, the arrangement of two sets of lifting drive components can easily lead to lifting errors in the materials in the two hoppers due to differences in actual installation errors, asynchronous maintenance, and wear. This results in differences in posture when the material is picked up and placed by the robotic arm, which in turn leads to differences in positioning accuracy when the material is moved to the punch press. This affects the stamping positioning accuracy and ultimately causes relatively large deviations in the products processed from materials in different hoppers within the same batch, resulting in poor product consistency and impacting customer satisfaction. Summary of the Invention

[0005] To improve the consistency of heat insulation covers processed in the same batch, this application provides an automated production line for heat insulation cover edge wrapping processing.

[0006] The automated production line for heat insulation cover edge wrapping provided in this application adopts the following technical solution: An automated production line for heat insulation cover edge wrapping includes a transfer device and a processing group. The processing group includes a feeding device, a first stamping device, a feeding assembly device, a second stamping device, and a material holding device arranged in sequence. The feeding device includes a first bearing mechanism, a horizontal drive mechanism, a vertical drive mechanism, a linkage mechanism, and a hopper mechanism. The fixed end of the horizontal drive mechanism is located on the bearing mechanism. The hopper mechanism is slidably connected to the bearing mechanism and drively connected to the moving end of the horizontal drive mechanism. The hopper mechanism includes a first feeding hopper and a second feeding hopper connected together. The first feeding hopper has a first lifting platform for pushing a first material pile, and the second feeding hopper has a second lifting platform for pushing a second material pile. The fixed end of the vertical drive mechanism is slidably connected to the bearing mechanism. The linkage mechanism is located on the bearing mechanism and connected to the hopper mechanism, and the linkage mechanism cooperates with the vertical drive mechanism. The mechanism is used to push the vertical drive mechanism, so that the telescopic end of the vertical drive mechanism selectively aligns with and pushes the first lifting platform or the second lifting platform upward. Both the first and second material piles are outer shells. The first stamping device is located on one side of the feeding device and is used to stamp the outer shell, so that the edge of the outer shell is turned up. The feeding assembly device is located on the side of the first stamping device away from the feeding device and is used to assemble heat insulation cotton and outer sheet on the outer shell and position and press the turned edge to form a part to be stamped. The second stamping device is located on the side of the feeding assembly device away from the first stamping device and is used to stamp the part to be stamped, so that the turned edge is wrapped to form a heat insulation cover. The material holding device is located on the side of the second stamping device away from the feeding assembly device and is used to carry the heat insulation cover. The transfer device is used to transport the outer shell, the part to be stamped, and the heat insulation cover within the processing group.

[0007] By adopting the above technical solution, the transfer device can transport the outer shell, the parts to be stamped, and the heat insulation cover within the processing group, ensuring smooth material flow between each processing stage. In the feeding device, the horizontal drive mechanism drives the hopper mechanism to slide on the carrying mechanism, allowing the first and second feeding hoppers to alternately feed materials to the feeding station; the linkage mechanism cooperates with the vertical drive mechanism to push the vertical drive mechanism, causing its telescopic end to selectively and quickly align and push the first or second lifting platform upwards, realizing the pushing of the first and second material piles, facilitating subsequent feeding operations. The first stamping device stamps the outer shell obtained from the feeding device, turning the edges of the outer shell flanged, preparing for subsequent assembly. The feeding assembly device assembles the heat insulation cotton and outer sheet on the stamped and flanged outer shell, and positions and presses the flanged edges to form the parts to be stamped. The second stamping device stamps the parts to be stamped, making the flanged edges wrap around to form the heat insulation cover. The material holding device is used to carry the finally processed heat insulation cover, facilitating unified collection and sorting. The entire automated production line achieves automated continuous production of heat insulation cover edge wrapping, improving production efficiency, and the precise coordination of each device ensures consistent product quality.

[0008] Optionally, the supporting mechanism includes a supporting frame and a guiding assembly. The guiding assembly is mounted on the supporting frame. The linkage mechanism includes a guiding member, a first linkage group, and a second linkage group. The upper end of the guiding member is connected to the hopper mechanism. The first linkage group and the second linkage group are both connected to the lower end of the guiding member. The first linkage group is used to push the vertical drive mechanism from below the first lifting platform to below the second lifting platform. The second linkage group is used to push the vertical drive mechanism from below the second lifting platform to below the first lifting platform.

[0009] By adopting the above technical solution, the support frame provides a supporting foundation for the entire support mechanism. The guide component is mounted on the support frame to guide the sliding of the hopper mechanism, ensuring its stability and accuracy. The upper end of the guide component is connected to the hopper mechanism, enabling the movement of the hopper mechanism to be transmitted to the linkage mechanism. The first linkage group can push the vertical drive mechanism from below the first lifting platform to below the second lifting platform, realizing the jacking of the second material pile; the second linkage group can push the vertical drive mechanism from below the second lifting platform to below the first lifting platform, realizing the jacking of the first material pile. Through the cooperation of the first and second linkage groups, the vertical drive mechanism can flexibly switch between the two lifting platforms, avoiding the jacking error problem caused by using two sets of lifting drive components, improving the consistency of material jacking, and thus improving the positioning accuracy of materials and the consistency of product quality in subsequent processing; at the same time, the linkage mechanism also improves the switching efficiency of the vertical drive mechanism and improves the continuity of processing.

[0010] Optionally, the first linkage group and the second linkage group have the same structure. The vertical drive mechanism includes a lifting drive component and a push plate. The push plate is located at the telescopic end of the lifting drive component, and the horizontal length of the push plate is greater than the horizontal length of the telescopic end of the lifting drive component. The first linkage group includes a locking component, a triggering component, a drive component, and a push component. The push component is slidably connected to the guide component. The first end of the push component cooperates with the fixed end of the vertical drive mechanism. The locking component is located at a first preset position on the guide component and is used to selectively lock the push component. When the push plate is located below the first lifting platform, the triggering component is located on the push component. The first end of the triggering component cooperates with the push plate. When the push plate moves down to a preset height, the second end of the triggering component pushes the locking component to release the locking. The fixed end of the drive component is located on one side of the push component, and the telescopic end of the drive component is used to push the second end of the push component.

[0011] By adopting the above technical solution, the first and second linkage groups have identical structures, making the overall structure more regular and unified, and facilitating design, manufacturing, and maintenance. The lifting drive component in the vertical drive mechanism can drive the push plate to move up and down. The horizontal length of the push plate is greater than the horizontal length of the telescopic end of the lifting drive component, increasing the contact area with the first or second lifting platform and more stably pushing the material pile. Simultaneously, the horizontally protruding part can push the trigger component, thereby releasing the locking mechanism. The push component is slidably connected to the guide component, allowing it to move smoothly under the guidance of the guide component. Its first end cooperates with the fixed end of the vertical drive mechanism, enabling the vertical drive mechanism to switch positions between the first and second lifting platforms. The locking component is located at the first preset position of the guide component. When the push plate is below the first lifting platform, it can selectively lock the push component, allowing the vertical drive mechanism to stably remain in the corresponding position. The trigger component is located on the push component, with its first end cooperating with the push plate. When the push plate moves down to a preset height, the second end of the trigger component pushes the locking component to release the locking mechanism, unlocking the push component and creating conditions for the drive component to move. The fixed end of the drive component is located on one side of the push component, and its telescopic end pushes the second end of the push component, thereby driving the vertical drive mechanism to move from under one lifting platform to under another lifting platform, realizing the pushing of material piles in different silos. This avoids the problem of material lifting error that is easily caused by using two sets of lifting drive components, improves the consistency and accuracy of material lifting, and thus improves the consistency and quality of product processing.

[0012] Optionally, the pushing assembly includes a first connecting member, a second connecting member, and a third connecting member. The two ends of the second connecting member are respectively connected to the first end of the first connecting member and the first end of the third connecting member. The first connecting member and the second connecting member are L-shaped in the horizontal plane, and the second connecting member and the third connecting member are L-shaped in the vertical plane. The second end of the first connecting member cooperates with the fixed end of the lifting drive member. The second connecting member is slidably connected to the support frame. The second end of the third connecting member is slidably connected to the guide member, and the second end of the third connecting member is used to cooperate with the snap-fit ​​assembly.

[0013] By adopting the above technical solution, the pushing component includes a first connecting member, a second connecting member, and a third connecting member. The two ends of the second connecting member are respectively connected to the first and third connecting members. The first and second connecting members are L-shaped in the horizontal plane, and the second and third connecting members are L-shaped in the vertical plane, giving the pushing component a stable mechanical structure. The second end of the first connecting member cooperates with the fixed end of the lifting drive component, effectively transmitting power and driving the lifting drive component to move. The second connecting member is slidably connected to the support frame, providing stable guidance for the movement of the pushing component and ensuring smooth movement. The second end of the third connecting member is slidably connected to the guide component and can cooperate with the snap-fit ​​component, allowing the pushing component to be snapped and fixed at a specific position, ensuring accurate and stable positioning of the lifting drive component during operation. This guarantees the stability and accuracy of the pushing operation on the first or second lifting platform, thereby improving the feeding efficiency and overall operational stability of the automated production line for heat insulation cover edge processing.

[0014] Optionally, the triggering component includes a movable member, a first rack, a gear, a second rack, and an elastic reset member. The movable member is vertically slidably connected to the pushing component, and a first end of the movable member engages with the pushing plate. The first rack is connected to the second end of the movable member. The gear is rotatably connected to the pushing component. Both the first rack and the second rack are vertically slidably connected to the pushing component. The first rack and the second rack are respectively located on both sides of the gear and both mesh with the gear. The elastic reset member is located below the first rack, and the upper end of the second rack is used to push the locking component to release the locking.

[0015] By adopting the above technical solution, the moving part cooperates with the push plate. When the push plate moves down to the preset height, the moving part can slide vertically on the push assembly, driving the first rack connected to it to move. When the first rack moves, it meshes with the gear, driving the gear to rotate, thereby causing the second rack meshing with the other side of the gear to slide vertically. After the second rack slides, its upper end pushes against the locking assembly, thereby releasing the locking. The elastic reset part can restore the trigger assembly to its initial state after completing the action, ensuring the continuous and stable operation of the trigger assembly, realizing the automatic control of the locking state of the push assembly by the locking assembly, ensuring that the vertical drive mechanism can accurately switch the lifting platform of the push assembly, and improving the working efficiency and stability of the feeding device.

[0016] Optionally, the guide member is provided with a sliding groove and a snap-fit ​​groove. The snap-fit ​​groove is located on one side of the sliding groove. The upper end of the pushing component is slidably connected to the sliding groove. The snap-fit ​​component includes an elastic element and a wedge. The upper end of the elastic element is connected to the top of the snap-fit ​​groove. The wedge is connected to the lower end of the elastic element. The inclined surface of the wedge is away from the first rack and is used to selectively snap the pushing component. The triggering component is used to push the wedge upward.

[0017] By adopting the above technical solution, the sliding groove on the guide provides a path for the sliding of the pushing component, ensuring that the pushing component can move along a specific trajectory; the locking groove is used to accommodate the locking component, facilitating the locking component to perform its locking function. The upper end of the pushing component is slidably connected to the sliding groove, allowing the pushing component to move smoothly on the guide, thereby driving the vertical drive mechanism to accurately move to the designated position. The elastic element in the locking component connects the top of the locking groove and the wedge. The elastic element provides elastic force, allowing the wedge to stably lock the pushing component, restricting the position of the pushing component and ensuring that the pushing plate is accurately aligned with the first lifting platform or the area below the second lifting platform. The inclined surface of the wedge is away from the first rack. This arrangement allows the pushing component to release the locking under specific conditions, improving the stability and reliability of the locking. When the pushing plate moves down to a preset height, the trigger component pushes the wedge upward, thereby releasing the locking and realizing the movement of the pushing component. This allows the vertical drive mechanism to switch between different lifting platforms to push the material piles in different hoppers.

[0018] Optionally, the first linkage group and the second linkage group are interconnected.

[0019] By adopting the above technical solution, the first and second linkage groups are interconnected, enabling them to coordinate their actions during operation. When the vertical drive mechanism needs to be pushed from under the first lifting platform to under the second lifting platform, the first linkage group plays a pushing role. Simultaneously, because it is connected to the second linkage group, it can drive the second linkage group to move synchronously, preparing for the subsequent pushing of the vertical drive mechanism from under the second lifting platform back to under the first lifting platform. When the vertical drive mechanism needs to be pushed from under the second lifting platform to under the first lifting platform, the second linkage group plays a pushing role. Again, because it is connected to the first linkage group, it can drive the first linkage group to move synchronously, thus ensuring that the vertical drive mechanism can accurately switch between the two lifting platforms throughout the entire feeding process. This achieves orderly lifting of materials in the two hoppers, improves feeding efficiency, and ensures the stable operation of the production line.

[0020] Optionally, the feeding device includes a feeding robot, a positioning mechanism, and a double-sheet detection mechanism, all mounted on the bearing mechanism. The double-sheet detection mechanism is located on the side of the positioning mechanism away from the hopper mechanism, and the feeding robot is mounted on one side of the positioning mechanism.

[0021] By adopting the above technical solution, the loading robot can grab and transport the outer shell from the hopper mechanism to the positioning mechanism; the positioning mechanism can position the transported outer shell so that it is accurately in the right position; the double-sheet detection mechanism can detect the positioned outer shell to prevent multiple outer shells from sticking together, ensuring the accuracy of subsequent processing and guaranteeing product quality.

[0022] Optionally, the positioning mechanism includes a positioning platform and a pushing component. The positioning platform is mounted on the supporting mechanism. The fixed end of the pushing component is located on the positioning platform. The telescopic end of the pushing component is used to push the first end of the outer shell on the positioning platform so that the second end of the outer shell is located between the two detection heads of the double-sheet detection mechanism.

[0023] By adopting the above technical solution, the positioning platform is erected on the bearing mechanism, providing a basis for the placement and positioning of the shell; the pushing component is fixed on the positioning platform, and its telescopic end pushes the first end of the shell on the positioning platform, so that the second end of the shell is accurately positioned between the two detection heads of the double-sheet detection mechanism, thereby realizing the precise position adjustment of the shell before double-sheet detection, ensuring that the double-sheet detection mechanism can accurately detect whether there are multiple sheets of the shell stuck together, and improving the accuracy and reliability of the detection results.

[0024] Optionally, the supporting mechanism is provided with a feeding station, and the first feeding bin and the second feeding bin can be alternately located at the feeding station.

[0025] By adopting the above technical solution, the supporting mechanism is equipped with a feeding station, where the first and second feeding bins can alternately occupy the feeding station. This alternating arrangement of the first and second feeding bins at the feeding station enables continuous material supply. Simultaneously, this alternating feeding method makes the feeding process more flexible, facilitating the management and allocation of materials in different bins, further improving the overall production efficiency, flexibility, and stability of the production line.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the coordinated operation of the transfer device, feeding device, first stamping device, feeding assembly device, second stamping device and material holding device, automated continuous production is achieved, with stable cycle time and significantly increased production capacity; 2. A single vertical drive mechanism is used in conjunction with a linkage mechanism. The linkage mechanism can push the telescopic end of the vertical drive mechanism to selectively align and push the first or second lifting platform upward, avoiding lifting errors caused by actual installation errors, asynchronous maintenance, and differences in wear of the two sets of lifting drive components, thus improving product consistency. 3. The loading robot handles materials precisely, the positioning mechanism pushes the outer shell to position itself, and the double-sheet detection mechanism prevents errors, ensuring assembly quality.

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 10 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0040] like Figure 1 and Figure 2 As shown in the figure, this application discloses an automated production line for heat insulation cover edge processing (hereinafter referred to as the "production line"). The production line includes a transfer device 60 and a processing group, and adopts multi-station collaborative automated processing of heat insulation covers, which achieves the effects of improving production efficiency, ensuring product quality consistency, improving production safety, and realizing intelligent management.

[0041] The processing group consists of a feeding device 10, a first stamping device 20, a feeding assembly device 30, a second stamping device 40, and a material holding device 50, arranged sequentially. A transfer device 60 transports the outer shell, the parts to be stamped, and the heat insulation cover within the processing group. This layout and coordination allows for the orderly and efficient edge-wrapping of the heat insulation cover. Through the collaborative work of each device, problems such as lifting errors inherent in traditional processing methods are avoided, improving product consistency and production efficiency. The transfer device 60 can utilize existing robotic arm structures, including but not limited to high-speed four-axis swing-arm robotic arms.

[0042] like Figure 3 and Figure 4 As shown, specifically, the feeding device 10 includes a supporting mechanism 1, a horizontal drive mechanism 2, a vertical drive mechanism 3, a linkage mechanism 4, and a hopper mechanism 5. The supporting mechanism 1 serves to support and fix other components; it can be a frame structure, such as welded from metal profiles or plates, possessing a certain strength and stability. The fixed end of the horizontal drive mechanism 2 is mounted on the supporting mechanism 1, and the hopper mechanism 5 is slidably connected to the supporting mechanism 1 and drively connected to the moving end of the horizontal drive mechanism 2. The horizontal drive mechanism 2 can consist of two sets of rodless cylinders, arranged parallel and horizontally spaced.

[0043] like Figure 3 , Figure 4 and Figure 5As shown, the hopper mechanism 5 includes a first feeding hopper 51 and a second feeding hopper 52 connected to each other. The first feeding hopper 51 is equipped with a first lifting platform 511 for pushing a first material pile, and the second feeding hopper 52 is equipped with a second lifting platform 521 for pushing a second material pile. Both the first and second material piles are outer shells. The first feeding hopper 51 and the second feeding hopper 52 can be rectangular plate-shaped pieces used to store the outer shells. The first lifting platform 511 and the second lifting platform 521 can be pallets and vertical guide groups. The vertical guide group includes multiple guide rods surrounding the pallet. The pallet is set on the through groove of the feeding hopper, and the guide rods limit the movement of the pallet, allowing it to move vertically and push the material pile on the pallet upwards, facilitating subsequent feeding operations. The hopper mechanism 5 can be selected from existing structures as needed, as long as it can achieve the corresponding functions.

[0044] The fixed end of the vertical drive mechanism 3 is slidably connected to the bearing mechanism 1. The linkage mechanism 4 is mounted on the bearing mechanism 1 and connected to the hopper mechanism 5. The linkage mechanism 4 cooperates with the vertical drive mechanism 3 and is used to push the vertical drive mechanism 3 so that the telescopic end of the vertical drive mechanism 3 selectively aligns with and pushes the first lifting platform 511 or the second lifting platform 521 upward. In this way, only one vertical drive mechanism 3 is needed to lift the material in both hoppers, avoiding the lifting error problem caused by multiple lifting drive components in the traditional method.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the supporting mechanism 1 includes a supporting frame 11 and a guiding assembly 12, which is mounted on the supporting frame 11. The guiding assembly 12 can be a guide rail or a guide rod structure, providing guidance for the sliding of the hopper mechanism 5 and the vertical drive mechanism 3.

[0046] like Figure 4 , Figure 5 and Figure 6 As shown, the linkage mechanism 4 includes a guide member 41, a first linkage group 42, and a second linkage group 43. The upper end of the guide member 41 is connected to the hopper mechanism 5. The first linkage group 42 and the second linkage group 43 are both connected to the lower end of the guide member 41, and the first linkage group 42 and the second linkage group 43 are interconnected. The first linkage group 42 is used to push the vertical drive mechanism 3 from below the first lifting platform 511 to below the second lifting platform 521, and the second linkage group 43 is used to push the vertical drive mechanism 3 from below the second lifting platform 521 to below the first lifting platform 511.

[0047] like Figure 4 and Figure 7 As shown, the guide member 41 can be a strip structure with a guide groove 413. The guide groove 413 is slidably connected to the guide assembly 12 to provide guidance for the movement of the first linkage group 42 and the second linkage group 43.

[0048] The first linkage group 42 and the second linkage group 43 have the same structure and are symmetrically arranged on both sides of the vertical drive mechanism 3. The vertical drive mechanism 3 includes a lifting drive component and a push plate. The push plate is located at the telescopic end of the lifting drive component, and the horizontal length of the push plate is greater than the horizontal length of the telescopic end of the lifting drive component.

[0049] like Figure 4 , Figure 5 and Figure 8 As shown, the first linkage group 42 includes a locking component 421, a trigger component 422, a drive component 423, and a push component 424. The push component 424 is slidably connected to the guide component 41. The first end of the push component 424 cooperates with the fixed end of the vertical drive mechanism 3. The locking component 421 is located at a first preset position on the guide component 41 and is used to selectively lock the push component 424. When the push plate is located below the first lifting platform 511, since the trigger component 422 is located on the push component 424, the first end of the trigger component 422 cooperates with the push plate. When the push plate moves down to a preset height, the second end of the trigger component 422 pushes the locking component 421 to release the lock. The fixed end of the drive component 423 is located on one side of the push component 424, and the telescopic end of the drive component 423 is used to push the second end of the push component 424. Understandably, the preset height is lower than the minimum height of the lifting platform. This allows the hopper mechanism 5 to move horizontally after the lifting platform is lowered to its minimum height by the push plate. The push plate then continues to move down to the preset height, disengaging from the lifting platform and pushing the trigger component 422. This achieves a position change for the lifting drive component, causing it to re-engage with another engagement component 421, thus ensuring stable and accurate positioning below the other lifting platform. Through the linkage mechanism 4, the lifting drive component can move the hopper mechanism 5 horizontally even before disengaging from the lifting platform. The two sets of engagement components 421 ensure accurate positioning of the lifting drive component below the lifting platform, avoiding the need for separate readjustment of the lifting drive component's position after the hopper mechanism 5 needs to be repositioned. The drive component 423 can be a spring mounted on a straight rod, or a telescopic structure such as a cylinder, hydraulic cylinder, or electric telescopic lever. Its position can be determined as needed, allowing the lifting drive component to move by pushing after disengaging. The first preset position can be determined based on the position that enables alignment and engagement. The engagement component of the second linkage group 43 is located in the second preset position, and its function is similar to that of the first preset position.

[0050] The pushing component 424 includes a first connecting member 4241, a second connecting member 4242, and a third connecting member 4243. The two ends of the second connecting member 4242 are respectively connected to the first ends of the first connecting member 4241 and the first ends of the third connecting member 4243. The first connecting member 4241 and the second connecting member 4242 are L-shaped in the horizontal plane, and the second connecting member 4242 and the third connecting member 4243 are L-shaped in the vertical plane. The second end of the first connecting member 4241 cooperates with the fixed end of the lifting drive component. The second connecting member 4242 is slidably connected to the support frame 11. The second end of the third connecting member 4243 is slidably connected to the guide member 41, and the second end of the third connecting member 4243 is used to cooperate with the snap-fit ​​component 421.

[0051] like Figure 4 , Figure 5 and Figure 8 As shown, the triggering component 422 includes a movable member 4221, a first rack 4222, a gear 4223, a second rack 4224, and an elastic reset member 4225. The movable member 4221 is vertically slidably connected to the pushing component 424, and the first end of the movable member 4221 engages with the pushing plate. Specifically, the first end of the movable member 4221 is located below the pushing plate, and the two are relatively independent.

[0057] The implementation principle of this embodiment is as follows: Through the ingenious design of the feeding device 10, the linkage mechanism 4 enables a vertical drive mechanism 3 to alternately push the materials in the two hoppers, avoiding the lifting error problem caused by multiple lifting drive components in traditional dual-station feeding mechanisms, thus improving product consistency. The close cooperation between the various devices and the orderly transport of materials by the transfer device 60 within the processing group result in a high degree of automation in the edge-wrapping process of the heat insulation cover, significantly improving production efficiency. Simultaneously, the positioning mechanism 7 and the double-sheet detection mechanism 8 further ensure product quality. The layout and structural design of the entire production line meet the demands of modern industrial production for efficient and precise processing.

[0058] 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.
