Description

Technical Field

[0001] The present application relates to the technical field of backpack processing equipment, and particularly relates to a backpack hot press machine. Background Art

[0002] A backpack refers to a bag carried on the back. Its materials are diverse, and bags made of genuine leather, plastic materials, polyester, canvas, nylon, cotton and linen, etc. lead the fashion trend. In the process of backpack manufacturing, a backpack hot press machine is needed to firmly bond materials such as the fabric and leather of the backpack through heating or pressing. This kind of equipment is widely used in industries such as textiles, leather, and packaging, and plays an important role especially in the process of manufacturing high-quality backpacks.

[0003] In the prior art, a backpack hot press machine includes a workbench and a hot pressing plate slidably installed on the workbench. There is a hot pressing station on the workbench. After the backpack to be hot pressed is placed at the hot pressing station, by driving the hot pressing head to press down, it acts on the backpack. Under the action of high temperature and pressure, the moisture and air between the backpack materials are discharged, and the fiber structure gradually becomes compact, and finally a firm bond is formed.

[0004] However, in actual application, such a backpack hot press machine has low processing efficiency and is not suitable for hot pressing operations of a large number of backpacks. Therefore, there is an urgent need for a backpack hot press machine suitable for backpack hot pressing processing to improve the backpack hot pressing efficiency. Summary of the Invention

[0005] In order to improve the hot pressing efficiency of backpacks, the present application provides a backpack hot press machine.

[0006] The backpack hot press machine provided by the present application adopts the following technical solutions: A backpack hot press machine includes a workbench and a hot pressing plate slidably installed on the workbench. A first sliding frame is arranged below the hot pressing plate on the workbench. The first sliding frame is slidably installed on the workbench. The first sliding frame has a plurality of hot pressing stations for placing backpacks, and the plurality of hot pressing stations are arranged at intervals along the sliding direction of the first sliding frame; a first driving component is arranged on the workbench, and the first driving component is used to drive the first sliding frame to perform intermittent horizontal sliding along the surface of the workbench.

[0007] By adopting the above technical solutions, the first sliding frame is slidably installed on the workbench. When performing hot pressing operations, multiple backpacks to be hot pressed can be installed on the plurality of hot pressing stations of the first sliding frame one by one at a time, and then the first driving component is used to drive the first sliding frame to perform intermittent horizontal sliding along the surface of the workbench, so that the hot pressing plate can perform hot pressing operations on multiple backpacks in sequence; after all the backpacks are hot pressed, all the backpacks are taken off, and the next batch of backpacks to be hot pressed are reinstalled, greatly improving the hot pressing efficiency of backpacks.

[0008] Optionally, the side wall of the first sliding frame is provided with a plurality of mounting plates for the backpack to be mounted thereon, the plurality of mounting plates are arranged at intervals along the length direction of the first sliding frame, and the upper surface of each mounting plate forms the hot pressing station; the mounting plates are provided with a clamping assembly for clamping the backpack.

[0009] By adopting the above technical solution, when installing the backpack, the opening of the backpack is aligned with the mounting plate and sent in so that the backpack is sleeved on the mounting plate. The clamping assembly can clamp and fix the backpack so that the surface of the backpack to be hot-pressed faces upward, so as to facilitate the hot-pressing operation of the backpack.

[0010] Optionally, the clamping assembly includes a clamping bar and a first spring, the clamping bar is slidably installed above the mounting plate, and two clamping bars are provided and symmetrically distributed on both sides of the upper surface of the mounting plate; the first spring is arranged between the clamping bar and the mounting plate, and under normal conditions, the first spring forces the clamping bar to move downward and abut against the surface of the backpack.

[0011] By adopting the above technical solution, when installing the backpack, the clamping bar is pulled to force the clamping bar to separate from the surface of the mounting plate, and then the backpack is put on the mounting plate, and the clamping bar is loosened. Under the action of the first spring, the clamping bar abuts against the surface of the backpack to be hot-pressed to limit the backpack, thereby reducing the possibility of the backpack moving freely during the movement of the first sliding frame and causing the hot-pressing position to change.

[0012] Optionally, a tensioning rod is provided at the bottom of each mounting plate, and the backpack is simultaneously sleeved on the mounting plate and the tensioning rod; one end of the tensioning rod is slidably installed on the first sliding frame; a guide block is provided on the surface of the workbench, and the guide block has a guide surface for guiding the tensioning rod to slide; when the mounting plate slides to just below the hot pressing plate, the guide surface of the guide block forces the tensioning rod corresponding to the mounting plate to move downward to tighten the backpack.

[0013] By adopting the above technical solution, when the backpack is installed, the backpack is simultaneously sleeved on the mounting plate and the tensioning rod. The backpack is first preliminarily fixed by the clamping assembly, and then the first sliding frame is moved to make the mounting seat slide to the bottom of the hot pressing plate. At this time, the guide block forces the tensioning rod to move downward through the guide surface to expand the distance between the tensioning rod and the mounting plate, thereby tightening the backpack and reducing the possibility of wrinkles on the surface of the backpack to be hot pressed during the hot pressing process, thereby improving the hot pressing quality.

[0014] Optionally, an embedding groove is formed on the upper surface of the mounting plate. A support bar is arranged in the embedding groove. The support bar and the clamping bar are arranged oppositely. A second spring is arranged between the support bar and the inner wall of the embedding groove. Under normal conditions, the second spring forces the support bar to abut against the inner surface of the backpack. When the tension rod tightens the backpack, the contact between the clamping bar and the backpack and the contact between the support bar and the backpack both change from surface contact to line contact.

[0015] By adopting the above technical solution, under normal conditions, the clamping bar abuts against the outer surface of the backpack under the action of the first spring, and the support bar abuts against the inner surface of the backpack under the action of the second spring (that is, the contact between the clamping bar and the backpack and the contact between the support bar and the backpack are both surface contacts). After the mounting seat slides to the lower side of the hot pressing plate, the tension rod moves downward at this time to tighten the backpack. The backpack drives the clamping bar and the support bar to rotate at a certain angle through the surface friction force, so as to change from surface contact to line contact. Such a design can, on the one hand, reduce the friction between the backpack and the clamping bar and between the backpack and the support bar, so as to facilitate the tension rod to tighten the backpack. On the other hand, when the tension rod is driven to move upward after the hot pressing on the backpack surface is completed, the clamping bar and the support bar respectively reset under the action of the first spring and the second spring to relax the backpack, which is not only convenient for taking out the backpack after hot pressing is completed, but also convenient for the backpack after hot pressing to recover its deformation in time.

[0016] Optionally, a rotating shaft is rotatably installed on the workbench. The first driving assembly includes a driving bar, a driving cam, an eccentric rod and a driving member. The driving bar is arranged on the side wall of the first sliding frame, and both ends of the driving bar extend along the length direction of the first sliding frame. The driving cam is arranged on the outer peripheral wall of the rotating shaft. The eccentric rod is arranged on the surface of the driving cam, and the eccentric rod and the rotating shaft are eccentrically arranged. A plurality of pushing grooves for the eccentric rod to turn into are formed on the side wall of the driving bar, and the plurality of pushing grooves are arranged at intervals along the length direction of the driving bar. When the driving cam drives the eccentric rod to turn into the pushing groove, the eccentric rod forces the driving bar to slide through the inner wall of the pushing groove. The driving member is arranged on the workbench to drive the rotating shaft to rotate.

[0017] By adopting the above technical solution, when driving the backpack into the hot pressing station for hot pressing, the driving member drives the rotating shaft to rotate, so that the driving cam can drive the eccentric rod to perform "revolution" around the central axis of the rotating shaft. When the eccentric rod rotates into the pushing groove, with the rotation of the driving cam, the eccentric rod can force the driving strip to slide along the inner wall of the pushing groove, thereby driving the first sliding frame to bring the backpack directly below the hot pressing plate. With the continuous rotation of the rotating shaft, when the eccentric rod rotates out of the pushing groove, at this time, the driving strip stops sliding due to the loss of the pushing force of the eccentric rod, so as to facilitate the hot pressing operation of the hot pressing plate on the backpack; the combination of multiple pushing grooves and eccentric rods enables the first sliding frame to perform intermittent sliding, so as to intermittently send the backpacks at multiple hot pressing stations one by one to the bottom of the hot pressing plate for hot pressing, improving the hot pressing efficiency and operation convenience of the overall structure.

[0018] Optionally, a positioning arc strip is provided on the surface of the driving cam, and the virtual central axis of the positioning arc strip coincides with the central axis of the rotating shaft; a plurality of positioning arc grooves are formed in the side wall of the driving strip, and the plurality of positioning arc grooves are arranged at intervals along the length direction of the driving strip, and the plurality of positioning arc grooves and the plurality of pushing grooves are arranged in a staggered manner; when the eccentric rod rotates out of the pushing groove, the positioning arc strip is embedded in the positioning arc groove to limit the free sliding of the driving strip; when the eccentric rod rotates into the pushing groove, the positioning arc strip disengages from the positioning arc groove.

[0019] By adopting the above technical solution, the setting of the positioning arc strip enables the positioning arc strip to be embedded in the positioning arc groove after the eccentric rod rotates out of the pushing groove, so as to limit the driving strip, reducing the possibility of the driving strip sliding freely under the action of inertia or external pushing force, and improving the stability of the overall structure.

[0020] Optionally, a second sliding frame is slidably installed above the workbench, the hot pressing plate is arranged on the second sliding frame, and the hot pressing plate is slidably installed on the workbench through the second sliding frame; a second driving component is arranged between the second sliding frame and the rotating shaft, and the second driving component is used to drive the second sliding frame to lift.

[0021] By adopting the above technical solution, the second driving component drives the second sliding frame to lift, so as to drive the hot pressing plate to lift, so that the hot pressing plate can perform hot pressing operations on the backpacks that slide below the hot pressing plate.

[0022] Optionally, the second driving component includes a driving disk and a driving rod. The driving disk is coaxially connected to the outer peripheral wall of the rotating shaft. One end of the driving rod is connected to the second sliding frame, and the other end abuts against the outer peripheral wall of the driving disk. First and second pushing surfaces are respectively formed on the outer peripheral wall of the driving disk. When the eccentric rod turns into the pushing groove, the driving rod abuts against the first pushing surface, and the second sliding frame forces the hot pressing plate to lift off the hot pressing station. When the eccentric rod turns out of the pushing groove, the driving rod abuts against the second pushing surface, and the second sliding frame forces the hot pressing plate to press against the surface of the backpack within the hot pressing station.

[0023] By adopting the above technical solution, when the eccentric rod turns into the pushing groove (i.e., when the eccentric rod drives the first sliding frame to slide), at this time, the driving rod abuts against the first pushing surface, and the second sliding frame is forced to lift by the driving rod, so that the hot pressing plate lifts off the hot pressing station, facilitating the first sliding frame to move the next backpack under the hot pressing plate for hot pressing operation. As the eccentric rod rotates, when the eccentric rod turns out of the pushing groove (i.e., when the driving bar is in a stationary state), at this time, the driving rod abuts against the second pushing surface, thereby forcing the second sliding frame to move downward, so that the hot pressing plate can press against the surface of the backpack within the hot pressing station. Such a design enables the sliding of the first sliding frame and the lifting and lowering of the second sliding frame to be synchronized, greatly improving the operation convenience of the overall structure.

[0024] Optionally, an embedding groove for the driving disk to be embedded is formed at one end of the driving rod away from the second sliding frame, and a rolling wheel is rotatably installed in the embedding groove, and the outer peripheral wall of the rolling wheel abuts against the outer peripheral wall of the driving disk.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the arrangement of multiple hot pressing stations, the first sliding frame is slidably installed on the workbench. When performing hot pressing operations, multiple backpacks to be hot pressed can be correspondingly installed on multiple hot pressing stations of the first sliding frame at one time, and then the first driving component is used to drive the first sliding frame to perform intermittent horizontal sliding along the surface of the workbench, so that the hot pressing plate can sequentially perform hot pressing operations on multiple backpacks. After all the backpacks are completely hot pressed, all the backpacks are taken off and the next batch of backpacks to be hot pressed are reinstalled, greatly improving the hot pressing efficiency of the backpacks. 2. Through the arrangement of the tensioning rod, when installing the backpack, the backpack is simultaneously sleeved on the mounting plate and the tensioning rod. First, the backpack is preliminarily fixed by the clamping component, and then the first sliding frame is moved so that the mounting seat slides under the hot pressing plate. At this time, the guiding block forces the tensioning rod to move downward through the guiding surface to expand the distance between the tensioning rod and the mounting plate, thereby tensioning the backpack and reducing the possibility of wrinkles appearing on the surface of the backpack to be hot pressed during the hot pressing process, and further improving the hot pressing quality. 3. By setting up the driving bar, driving cam, and eccentric rod, when driving the backpack into the hot pressing station for hot pressing, the driving member drives the rotating shaft to rotate, enabling the driving cam to drive the eccentric rod to perform "revolution" around the central axis of the rotating shaft. When the eccentric rod rotates into the pushing groove, as the driving cam rotates, the eccentric rod can force the driving bar to slide through the inner wall of the pushing groove, thereby driving the first sliding frame to bring the backpack under the hot pressing plate. As the rotating shaft continues to rotate, when the eccentric rod rotates out of the pushing groove, at this time, the driving bar stops sliding due to the loss of the push of the eccentric rod, facilitating the hot pressing operation of the hot pressing plate on the backpack; the combination of multiple pushing grooves and eccentric rods enables the first sliding frame to perform intermittent sliding, intermittently feeding the backpacks at multiple hot pressing stations one by one to the bottom of the hot pressing plate for hot pressing, improving the hot pressing efficiency and operation convenience of the overall structure.

Detailed implementation manners

[0028] The following Figures 1-10 further elaborates on this application in detail. Embodiment 1

[0029] An embodiment of this application discloses a backpack hot press.

[0030] Referring to Figure 1 and Figure 2 a backpack hot press includes a workbench 1 and a hot pressing plate 2. A mounting bracket 13 is fixedly installed on the upper surface of the workbench 1. The hot pressing plate 2 (the structure of the hot pressing plate 2 is a prior art, and its internal structure will not be elaborated too much here) is slidably installed on the mounting bracket 13 to be able to lift, and the hot pressing plate 2 is slidably installed on the workbench 1 through the mounting bracket 13. A sliding rail 14 is fixedly installed on the upper surface of the workbench 1. The two ends of the sliding rail 14 extend horizontally. A first sliding frame 3 is slidably installed on the sliding rail 14, and the first sliding frame 3 is slidably installed on the workbench 1 through the sliding rail 14.

[0031] A plurality of mounting plates 32 are fixedly installed on the side wall of the first sliding frame 3. The plate surface of each mounting plate 32 is horizontally arranged. The plurality of mounting plates 32 are arranged at intervals along the length direction of the first sliding frame 3. The upper surface of the mounting plate 32 forms a hot pressing station 31 for placing a backpack, and the plurality of mounting plates 32 form a plurality of hot pressing stations 31.

[0032] Referring to Figure 2 and Figure 3, a clamping assembly 5 for clamping the backpack is provided on each mounting plate 32. In this embodiment, the clamping assembly 5 includes a clamping strip 51 and a first spring 52. The clamping strip 51 is slidably mounted above the mounting plate 32. There are two clamping strips 51, which are symmetrically distributed on both sides of the upper surface of the mounting plate 32; a fixing strip 34 is fixedly mounted on the side wall of the first sliding frame 3. In this embodiment, the clamping strip 51 is provided with a guide rod 511. The guide rod 511 is vertically arranged. One end of the guide rod 511 is fixedly connected to the top wall of the clamping strip 51, and the other end passes through the fixing strip 34. The clamping strip 51 is slidably mounted on the fixing strip 34 of the first sliding frame 3 through the guide rod 511 so as to be able to lift and lower; a force-applying strip 512 is connected between the two clamping strips 51; with such a setting, the two clamping strips 51 are connected in series by the force-applying strip 512. By pulling the force-applying strip 512, the two clamping strips 51 can be driven to lift simultaneously, so as to facilitate the installation of the backpack.

[0033] The first spring 52 is sleeved on the outer peripheral side of the guide rod 511. One end of the first spring 52 is fixedly connected to the fixing strip 34, and the other end is fixedly connected to the clamping strip 51. Under normal conditions, the first spring 52 forces the clamping strip 51 to move downward and abut against the surface of the backpack.

[0034] A first driving assembly is provided on the workbench 1. The first driving assembly is used to drive the first sliding frame 3 to perform intermittent horizontal sliding along the surface of the workbench 1. In this embodiment, the first driving assembly can be set as a linear motor (the linear motor is a prior art, and its structure will not be elaborated too much here, and it is not shown in the figure). The first sliding frame 3 is driven by the linear motor to perform intermittent sliding along the length direction of the slide rail 14, so that the hot pressing stations 31 of multiple mounting plates 32 can be sequentially moved under the hot pressing plate 2 in turn for hot pressing operations.

[0035] Refer to Figure 1 , in this embodiment, the driving source for driving the hot pressing plate 2 to lift and lower is a lifting cylinder 15. The cylinder body of the lifting cylinder 15 is fixedly mounted on the mounting frame 13, and the piston rod of the lifting cylinder 15 is fixedly connected to the hot pressing plate 2. When the piston rod of the lifting cylinder 15 extends outwards, the hot pressing plate 2 moves downward to perform a hot pressing operation on the backpack outside the mounting plate 32 moved under the hot pressing plate 2.

[0036] The implementation principle of Embodiment 1 of this application is as follows: The first sliding frame 3 is slidably installed on the workbench 1. When performing hot pressing operations, multiple backpacks to be hot pressed can be sleeved on the outside of the mounting plate 32 of the first sliding frame 3 one by one, and clamped and fixed by the clamping strips 51. Then, the first sliding frame 3 is driven to perform intermittent horizontal sliding along the surface of the workbench 1, so as to successively send multiple backpacks to be hot pressed under the hot pressing plate 2, so that the hot pressing plate 2 can perform hot pressing operations on multiple backpacks in sequence; after all backpacks are completely hot pressed, all backpacks are removed, and the next batch of backpacks to be hot pressed are reinstalled, greatly improving the hot pressing efficiency of the backpacks. Embodiment 2

[0037] This application example discloses a backpack hot press.

[0038] The difference between the backpack hot press disclosed in the embodiment of this application and Embodiment 1 lies in: Referring to Figure 4 、 Figure 5 In this embodiment, a tensioning rod 33 is provided at the bottom of each mounting plate 32, and the backpack is sleeved on the mounting plate 32 and the tensioning rod 33 at the same time; a lifting groove 35 is formed in the side wall of the first sliding frame 3, and both ends of the lifting groove 35 extend in the height direction. A lifting block 36 is slidably installed in the lifting groove 35. One end of the tensioning rod 33 is rotatably connected to the lifting block 36, and the tensioning rod 33 is slidably and rotatably installed on the side wall of the first sliding frame 3 through the lifting block 36: A third spring (not shown in the figure) is installed in the lifting groove 35. One end of the third spring is fixedly connected to the lifting block 36, and the other end is fixedly connected to the inner wall of the lifting groove 35. Under normal conditions, the third spring forces the lifting block 36 to lift, so as to force the tensioning rod 33 to lift.

[0039] Referring to Figure 4 、 Figure 6 On the surface of the workbench 1, a connecting plate 16 is fixedly installed. The connecting plate 16 is vertically arranged. The lower end of the connecting plate 16 is fixedly installed on the upper surface of the workbench 1, and the connecting plate 16 is located on the side of the first sliding frame 3 away from the mounting plate 32; a guiding block 11 is fixedly installed on the surface of the connecting plate 16 close to the first sliding frame 3. The guiding block 11 has a guiding surface 111 for guiding the tensioning rod 33 to slide; there are two guiding surfaces 111. When the mounting plate 32 slides under the hot pressing plate 2, the guiding surface 111 of the guiding block 11 forces the corresponding tensioning rod 33 of the mounting plate 32 to move down, so that the tensioning rod 33 tightens the backpack.

[0040] The implementation principle of Embodiment 2 of this application is as follows: When the backpack is installed, the backpack is sleeved on the mounting plate 32 and the tension rod 33 at the same time. First, the backpack is preliminarily fixed by the clamping strip 51, and then the first sliding frame 3 is moved so that the mounting seat slides to directly below the hot pressing plate 2. At this time, the guiding block 11 forces the tension rod 33 to move downward through the guiding surface 111 to expand the distance between the tension rod 33 and the mounting plate 32, thereby tightening the backpack and reducing the possibility that the surface of the backpack to be hot-pressed appears wrinkled during the hot pressing process, and thus improving the hot pressing quality. Embodiment 3

[0041] An embodiment of this application discloses a backpack hot press.

[0042] The difference between the backpack hot press disclosed in the embodiment of this application and Embodiment 1 lies in: Referring to Figure 7 , in this embodiment, a rotating shaft 12 is rotatably installed on the workbench 1. The two ends of the rotating shaft 12 extend horizontally. The length direction of the rotating shaft 12 is perpendicular to the sliding direction of the first sliding frame 3; in this embodiment, the first driving assembly 4 includes a driving strip 41, a driving cam 42, an eccentric rod 43 and a driving member. The driving strip 41 is fixedly installed on the side wall of the first sliding frame 3 away from the mounting plate 32, and the two ends of the driving strip 41 extend along the length direction of the first sliding frame 3.

[0043] The driving cam 42 is fixedly installed on the outer peripheral wall of the rotating shaft 12. The eccentric rod 43 is installed on the surface of the driving cam 42. The eccentric rod 43 and the driving cam 42 can be rotatably connected so that the eccentric rod 43 can "rotate" around its own central axis; the eccentric rod 43 and the rotating shaft 12 are eccentrically arranged so that the eccentric rod 43 can "revolve" around the central axis of the rotating shaft 12. A plurality of pushing grooves 411 for the eccentric rod 43 to turn into are formed on the side wall of the driving strip 41, and the plurality of pushing grooves 411 are arranged at intervals along the length direction of the driving strip 41.

[0044] When the driving cam 42 drives the eccentric rod 43 to turn into the pushing groove 411, the eccentric rod 43 forces the driving strip 41 to slide along its own length direction through the inner wall of the pushing groove 411; the driving member is arranged on the workbench 1 to drive the rotating shaft 12 to rotate. In this embodiment, the driving member is set as a driving motor (not shown in the figure), and the driving motor is fixedly installed on the upper surface of the workbench 1. The output shaft of the driving motor is coaxially connected to the rotating shaft 12. It should be noted that, in this embodiment, the driving motor is a servo motor to enable the forward and reverse rotation of the rotating shaft 12.

[0045] In this embodiment, a positioning arc strip 421 is fixedly installed on the surface of the driving cam 42 close to the surface of the first sliding frame 3, and the virtual central axis of the positioning arc strip 421 coincides with the central axis of the rotating shaft 12; a plurality of positioning arc grooves 412 are formed in the side wall of the driving strip 41, and the plurality of positioning arc grooves 412 are arranged at intervals along the length direction of the driving strip 41, and the plurality of positioning arc grooves 412 and the plurality of pushing grooves 411 are arranged in a staggered manner; when the eccentric rod 43 rotates out of the pushing groove 411, the positioning arc strip 421 is embedded in the positioning arc groove 412 to limit the free sliding of the driving strip 41; when the eccentric rod 43 rotates into the pushing groove 411, the positioning arc strip 421 disengages from the positioning arc groove 412.

[0046] The implementation principle of Embodiment 3 of this application is as follows: when driving the backpack into the hot pressing station 31 for hot pressing, the rotating shaft 12 is driven to rotate by the driving member, so that the driving cam 42 can drive the eccentric rod 43 to perform "revolution" around the central axis of the rotating shaft 12. When the eccentric rod 43 rotates into the pushing groove 411, as the driving cam 42 rotates, the eccentric rod 43 can force the driving strip 41 to slide through the inner wall of the pushing groove 411, thereby driving the first sliding frame 3 to slide, so as to bring the backpack under the hot pressing plate 2. As the rotating shaft 12 continues to rotate, when the eccentric rod 43 rotates out of the pushing groove 411, the driving strip 41 stops sliding due to the loss of the push of the eccentric rod 43. At this time, the backpack can be hot pressed by the hot pressing plate 2; the combination of the plurality of pushing grooves 411 and the eccentric rod 43 enables the first sliding frame 3 to perform intermittent sliding, so as to intermittently send the backpacks on the plurality of mounting plates 32 one by one to the bottom of the hot pressing plate 2 for hot pressing, improving the hot pressing efficiency and operation convenience of the overall structure.

[0047] The setting of the positioning arc strip 421 enables the positioning arc strip 421 to be embedded in the positioning arc groove 412 after the eccentric rod 43 rotates out of the pushing groove 411, so as to limit the driving strip 41, reducing the possibility of the driving strip 41 sliding freely under the action of inertia or external pushing, and improving the stability of the overall structure. Embodiment 4

[0048] This application embodiment discloses a backpack hot press.

[0049] The difference between the backpack hot press disclosed in the embodiment of this application and Embodiment 3 lies in: Refer to Figure 8 、 Figure 9, in this embodiment, the mounting bracket 13 (not shown in this embodiment) is connected to a second sliding bracket 6. The second sliding bracket 6 is slidably mounted on the mounting bracket 13 to be able to move up and down. The hot pressing plate 2 is fixedly mounted on the second sliding bracket 6. The hot pressing plate 2 is slidably mounted on the mounting bracket 13 of the workbench 1 through the second sliding bracket 6. A second driving assembly 7 is provided between the second sliding bracket 6 and the rotating shaft 12. The second driving assembly 7 is used to drive the second sliding bracket 6 to move up and down (that is, the driving source of the hot pressing plate 2 in this embodiment is set as the second driving assembly 7).

[0050] The second driving assembly 7 includes a driving disk 71 and a driving rod 72. The driving disk 71 is coaxially connected to the outer peripheral wall of the rotating shaft 12. The driving disk 71 is located on the side of the driving cam 42 away from the first sliding bracket 3. The driving rod 72 is vertically arranged. The upper end of the driving rod 72 is fixedly connected to the second sliding bracket 6. An embedding groove 721 for the driving disk 71 to be embedded is formed at the lower end of the driving rod 72. A rolling wheel 722 is rotatably mounted in the embedding groove 721. The outer peripheral wall of the rolling wheel 722 abuts against the outer peripheral wall of the driving disk 71.

[0051] In this embodiment, the outer peripheral wall of the driving disk 71 respectively forms a first pushing surface 711 and a second pushing surface 712. Both the first pushing surface 711 and the second pushing surface 712 are arc surfaces, and the virtual central axes of the first pushing surface 711 and the second pushing surface 712 coincide with the central axis of the rotating shaft 12. The outer diameter of the first pushing surface 711 is larger than the outer diameter of the second pushing surface 712. When the eccentric rod 43 turns into the pushing groove 411, the rolling wheel 722 of the driving rod 72 abuts against the first pushing surface 711 to force the second sliding bracket 6 to lift, and further force the hot pressing plate 2 to lift away from the hot pressing station 31.

[0052] When the eccentric rod 43 turns out of the pushing groove 411, the rolling wheel 722 of the driving rod 72 abuts against the second pushing surface 712 to force the second sliding bracket 6 to move down, and further force the hot pressing plate 2 to press on the surface of the backpack in the hot pressing station 31.

[0053] The implementation principle of Embodiment 4 of this application is as follows: When the eccentric rod 43 turns into the pushing groove 411 (that is, when the eccentric rod 43 drives the first sliding bracket 3 to slide), at this time, the driving rod 72 abuts against the first pushing surface 711, and forces the second sliding bracket 6 to lift through the driving rod 72, so that the hot pressing plate 2 lifts away from the hot pressing station 31, so as to facilitate the first sliding bracket 3 to move the next backpack under the hot pressing plate 2.

[0054] As the eccentric rod 43 rotates, when the eccentric rod 43 rotates out of the pushing groove 411 (i.e., when the driving strip 41 is in a stationary state), at this time, the driving rod 72 abuts against the second pushing surface 712, thereby forcing the second sliding frame 6 to move downward, so that the hot pressing plate 2 can be pressed against the surface of the backpack in the hot pressing station 31. Such a design enables the sliding of the first sliding frame 3 and the lifting and lowering of the second sliding frame 6 to be synchronized, greatly improving the operational convenience of the overall structure. Embodiment 5

[0055] An embodiment of the present application discloses a backpack hot press.

[0056] The difference between the backpack hot press disclosed in the embodiment of the present application and Embodiment 2 lies in: Referring to Figure 10 In this embodiment, the guide rod 511 is not provided on the clamping strip 51 (that is, the clamping strip 51 and the fixed strip 34 are only connected by the first spring 52). Under normal conditions, the bottom wall of the clamping strip 51 abuts against the outer surface of the backpack under the action of the first spring 52 (that is, the clamping strip 51 and the backpack are in surface contact). The force application strip 512 includes a force application sleeve 513 and two sliding rods 514. One ends of the two sliding rods 514 are respectively slidably inserted into the force application sleeve 513. The two sliding rods 514 are correspondingly arranged with the two clamping strips 51. One end of each sliding rod 514 away from the force application sleeve 513 is hinged to the corresponding clamping strip 51.

[0057] Two embedding grooves are formed on the upper surface of the mounting plate 32, and the two embedding grooves are correspondingly arranged with the two clamping strips 51. Each embedding groove is directly opposite to the corresponding clamping strip 51; a support strip 37 is installed in each embedding groove, and both ends of the support strip 37 extend along the length direction of the clamping strip 51. A second spring 38 is installed between the support strip 37 and the inner wall of the embedding groove. Under normal conditions, the second spring 38 forces the top wall of the support strip 37 to be flush with the upper surface of the mounting plate 32 to abut against the inner surface of the backpack (that is, the support strip 37 and the backpack are in surface contact). When the tightening rod 33 moves downward and tightens the backpack, the contact between the clamping strip 51 and the backpack and the contact between the support strip 37 and the backpack both change from surface contact to line contact.

[0058] The implementation principle of Embodiment 5 of the present application is: Under normal conditions, the clamping strip 51 abuts against the outer surface of the backpack under the action of the first spring 52, and the support strip 37 abuts against the inner surface of the backpack under the action of the second spring 38 (that is, the clamping strip 51 and the backpack, and the support strip 37 and the backpack are both in surface contact).

[0059] After the mounting seat slides to the lower side of the hot pressing plate 2, at this time, the tightening rod 33 moves downward to tighten the backpack. The backpack drives the clamping strip 51 and the support strip 37 to turn by a certain angle through the surface friction force, so as to change from surface contact to line contact.

[0060] Such a design can, on the one hand, reduce the friction between the backpack and the clamping strip 51 and between the backpack and the support strip 37, so as to facilitate the tensioning rod 33 to tension the backpack. On the other hand, when driving the tensioning rod 33 to move upward after the hot pressing on the backpack surface is completed, the clamping strip 51 is reset under the action of the first spring 52, and the support strip 37 is reset under the action of the second spring 38 to timely release the backpack, which is not only convenient for taking out the backpack after hot pressing is completed, but also reduces the possibility of irreversible deformation occurring on the backpack surface after hot pressing.

[0061] The above is the preferred embodiment of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
