Description
Technical Field
[0001] This utility model relates to the field of transfer machine structure, and in particular to a time-sharing, linkage-based heat transfer machine for insoles. Background Technology
[0002] Current insole heat transfer equipment generally suffers from low automation and disjointed process connections. Traditional transfer machines often employ a split drive structure, requiring independent power sources or complex electronic control programs to coordinate the transfer film displacement and heat pressing actions. This design has significant drawbacks: firstly, multiple power source systems lead to redundant energy consumption, and frequent motor starts and stops exacerbate equipment wear; secondly, while the introduction of electronic sensors and PLC control units enables timing management, signal interference is prone to occur in high-dust, high-humidity production environments, causing malfunctions of the heat pressing head. Especially in small-batch, multi-batch production, frequent programming and debugging severely impact operational efficiency and require a high level of operator skill. Utility Model Content
[0003] To address the shortcomings mentioned above in the background technology, this utility model provides a time-sharing, interconnected insole heat transfer machine.
[0004] The present invention adopts the following technical solution:
[0005] A time-sharing, interconnected heat transfer machine for shoe insoles, the machine comprising:
[0006] A workbench is provided, on which a machine base is fixed. A rotatable film-laying reel and a winding reel are respectively connected to both sides of the workbench. A transfer film with a printed pattern is wound on the film-laying reel. The winding reel rotates to wind up the transfer film from the film-laying reel, causing the transfer film to move parallel to the surface of a placement plate fixed to the workbench.
[0007] A hot press head is vertically slidably disposed on the machine base. One end of the hot press head is fixed with a connecting rod inside the machine base. The lower end of the connecting rod passes through the worktable and fixes a pressure ring. A first elastic element that provides an upward lifting force is disposed between the hot press head and the worktable.
[0008] The transmission assembly includes a transmission shaft, a first rotating shaft, a second rotating shaft, and a cam disposed under the worktable. Half gears and drive gears are spaced apart along the axial direction on the transmission shaft. The first rotating shaft is intermittently meshed with the half gears through the first gear. The second rotating shaft is meshed with the drive gear through the second gear. The first rotating shaft is connected to the winding reel in a transmission connection. The cam is fixedly mounted on the second rotating shaft.
[0009] In the first half of the rotation of the drive shaft, the half gear meshes with the first gear to drive the take-up reel to perform the film take-up action. At the same time, the drive shaft drives the cam to rotate through the meshing of the drive gear and the second gear. In the second half of the rotation of the drive shaft, the cam rotates downward on the connecting rod side to press down the pressure ring. The pressure ring overcomes the lifting force of the first elastic element and drives the hot press head to press down, pressing the transfer film against the placement plate.
[0010] In one possible implementation, the drive shaft fixes the handwheel, which is located outside the front of the worktable.
[0011] In one possible implementation, the transfer machine further includes a pedal, which is vertically adjustable below the worktable. The lifting and lowering of the pedal drives the drive shaft to rotate. When the pedal is lowered, it drives the drive shaft to rotate half a revolution, causing the half gear to mesh with the first gear. When the pedal is raised, it drives the drive shaft to continue half a revolution, causing the drive gear to mesh with the second gear.
[0012] In one possible implementation, the transfer machine further includes a linkage assembly comprising a first linkage, a second linkage, a third linkage, and an eccentric shaft. Two eccentric plates are fixed on the drive shaft, and the eccentric shaft is fixedly connected between the ends of the two eccentric plates that are offset from the axis of the drive shaft. The lower end of the first linkage is pivotally connected to the end of the pedal located within the worktable. The two ends of the second linkage are pivotally connected to a side plate below the worktable and the upper end of the first linkage, respectively. The two ends of the third linkage are pivotally connected to the middle part of the second linkage and the eccentric shaft, respectively.
[0013] In one possible implementation, the pedal is connected to the worktable via a second elastic element that provides an upward lifting force to the pedal.
[0014] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: In this utility model, the operator drives the transmission shaft of the transmission component to rotate one revolution. The transmission shaft is equipped with a half gear and a drive gear. During the first half revolution of the transmission shaft rotation, the half gear meshes with the first rotating shaft to drive the winding reel to wind up the transfer film, simultaneously driving the cam for pre-positioning. During the second half revolution of the transmission shaft rotation, the drive gear meshes with the second rotating shaft to drive the cam to press down the connecting rod, forcing the hot press head to overcome the resistance of the first elastic element and complete the heat transfer. This time-sharing linkage design achieves a complete process cycle through the movement and coordination between mechanical components, eliminating the dependence on electronic sensors and avoiding signal interference in the production environment that could lead to malfunctions of the hot press head. Simultaneously, the direct operation of the transmission shaft driven by the operator completely eliminates electric drive, significantly improving the energy efficiency of the equipment. It achieves zero-energy operation while ensuring process accuracy, avoiding frequent motor start-stop cycles that exacerbate equipment wear. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.
[0027] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
[0028] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.
[0029] This utility model provides a time-sharing, interconnected insole heat transfer machine, as shown in the attached figure. Figure 1 , 2 As shown in Figures 3 and 6, the transfer printing machine includes a worktable 1, a hot press head 2, and a transmission assembly 3. A base 11 is fixed to the worktable 1, and a placement plate 12 is fixed below the base 11. This placement plate 12 is used to place insoles with patterns to be printed. A rotatable film-laying tray 41 and a winding tray 42 are respectively connected to both sides of the base 11 on the worktable 1. A transfer film 43 with the printed pattern is wound on the film-laying tray 41. The winding tray 42 rotates to take up the transfer film 43 from the unwinding tray, causing the transfer film 43 to move parallel to the surface of the placement plate 12 fixed to the worktable 1. This allows the patterns printed on the transfer film 43 to move one by one to the placement plate 12. The hot press head 2 then presses the hot press head down onto the placement plate 12, transferring the patterns printed on the transfer film 43 to the surface of the insole on the placement plate through heat pressing.
[0030] Please refer to the appendix. Figure 4 and 5The hot press head 2 is vertically slidably mounted on the base 11. Its vertical sliding can be achieved by having guide holes (not shown in the attached diagram) on both sides of the top plate inside the base 11. The hot press head 2 is fixed to a lifting seat 21, and first guide posts 22 are fixed on both sides of the lifting seat 21. The two first guide posts 22 respectively adapt to pass through the two guide holes, thereby forming a vertical constraint on the hot press head 2 relative to the base 11. A connecting rod 23 is fixed to one end of the hot press head 2 inside the base 11. Specifically, the connecting rod 23 can be fixed to the lifting seat 21. The lower end of the connecting rod 23 passes through the worktable 1 and fixes the pressure ring 24. A first elastic element 25 providing upward lifting force is provided between the hot press head 2 and the worktable 1. Preferably, the first elastic element 25 can be a spring, and the first spring is sleeved outside the connecting rod 23. The first spring generates a lifting force that lifts the lifting seat 21 through its elastic force of stretching and restoring.
[0031] As attached Figure 7 and 8 As shown, the transmission assembly 3 includes a transmission shaft 31, a first rotating shaft 32, a second rotating shaft 33, and a cam 34 disposed below the worktable 1. Half gears 35 and drive gears 36 are axially spaced and mounted on the transmission shaft 31. The first gear 321 mounted on the first rotating shaft 32 meshes with the half gears 35 of the transmission shaft 31, and the second gear 331 mounted on the second rotating shaft 33 intermittently meshes with the drive gears 36 of the transmission shaft 31.
[0032] The first rotating shaft 32 and the take-up reel 42 are connected by a transmission. The transmission method can be that the end of the take-up reel 42 facing away from the worktable 1 and the first rotating shaft 32 are both fixed with synchronous pulleys 371. The two synchronous pulleys 371 are connected by a synchronous belt 372 through meshing. The rotation of the first rotating shaft 32 is synchronously driven by the transmission connection formed by the synchronous belt 372.
[0033] The cam 34 is fixedly mounted on the second rotating shaft 33, and in the initial state, the protruding part of the cam 34 is located below the connecting rod 23, i.e., attached. Figure 11 The state is shown. When the second rotating shaft 33 rotates, it drives the cam 34 to rotate downwards towards the connecting rod 23, causing the pressure ring 24 to descend. This pressure ring 24 forces the connecting rod 23 to descend, thereby driving the lifting seat 21 and the hot pressure head 2 to complete the downward pressing action. During this process, the first elastic element 25 is compressed and stores energy. Afterwards, as the second rotating shaft 33 continues to rotate, it drives the cam 34 to rotate away from the pressure ring 24. As the lifting seat 21 loses the pressure of the cam 34, the first elastic element 25 releases its elastic potential energy, causing the lifting seat 21 and the hot pressure head 2 to automatically rise upwards relative to the placement plate 12.
[0034] With the above structure, the working principle of this utility model is as follows:
[0035] The operator precisely positions the insole to be processed on the placement plate 12, then drives the drive shaft 31 to rotate one revolution. During the first half of the rotation of the drive shaft 31, the meshing of the half gear 35 and the first gear 321 drives the winding reel 42 to perform the film winding action, thereby driving the transfer film 43 to move on the placement plate 12 at a preset step distance, so that the new pattern accurately corresponds to the placement plate 12. At the same time, the protrusion of the cam 34 rotates to the top of the drive shaft 31, as shown in the attached figure. Figure 10 As shown, this forms a preparatory state;
[0036] Afterwards, when the drive shaft 31 continues to rotate and enters the second half of the rotation stage, the missing part of the half gear 35 does not mesh with the first gear 321 and enters the disengaged state. The take-up reel 42 does not perform the take-up action, and the transfer film 43 stops displacing. At the same time, the cam 34 rotates downward on the side of the drive shaft 31 near the connecting rod 23, so that the protrusion of the cam 34 presses down the pressure ring 24. The pressure ring 24 overcomes the lifting force of the first elastic element 25 and drives the hot press head 2 to press down, pressing the transfer film 43 onto the insole on the placement plate 12, thereby completing the single hot pressing process of the insole.
[0037] After completing a single hot-pressing process, the operator repeats the process of replacing the finished product and placing the insoles to be processed, and the equipment then enters the next work cycle. This periodic operation mechanism achieves precise alternation between the transfer film 43 displacement and the hot-pressing process through mechanical linkage timing control, forming a continuous production rhythm.
[0038] In the above working method, the first half of the rotation of the drive shaft 31 synchronously completes the pattern movement and positioning of the transfer film 43 and the phase adjustment of the cam 34. The second half of the rotation of the drive shaft 31 is dedicated to the hot pressing action of the hot press head 2, forming a process step of first moving the transfer film 43 and then controlling the hot press head 2 to press down. This time-sharing control strategy effectively isolates material displacement and hot pressing action, eliminating the risk of motion interference from the mechanical source. The standardized motion rhythm of each half-turn of the drive shaft 31, matched with the precise indexing function of the intermittent gear transmission mechanism, ensures that the transfer pattern on the transfer film 43 is strictly aligned according to the design spacing.
[0039] Another noteworthy feature is that the first half of the drive shaft 31 of the transmission component 3 drives the transfer film 43 to change position and prepares for the subsequent hot pressing action; the second half of the drive is dedicated to performing the hot pressing action. This time-sharing linkage design achieves a complete process cycle solely through the movement coordination between mechanical components, eliminating the reliance on electronic sensors. The linkage mechanism of the transmission mechanism ensures the reliability of the coordinated operation between the winding reel 42 and the hot pressing head 2, eliminating the risk of timing disruptions such as the hot pressing head 2 moving prematurely or the transfer film 43 moving lagging behind. During equipment operation, only a single power input is needed to distribute kinetic energy orderly to the winding reel 42 and the hot pressing head 2, ensuring absolute controllability of the process sequence and significantly improving the energy efficiency of the equipment. This allows the three major process stages—transfer film 43 positioning, hot pressing execution, and workpiece change—to proceed sequentially, fundamentally guaranteeing the stability of the production cycle and the accuracy of process repeatability.
[0040] The power source for the drive shaft 31 can be either the handwheel 5 or the pedal 6, as detailed below: Example
[0041] As attached Figure 6 As shown, the drive shaft 31 is fixed to the handwheel 5, which is located in an easily accessible position on the front of the worktable 1. After placing the insole to be processed on the placement plate 12, rotating the handwheel 5 one revolution will drive the drive shaft 31 to rotate one revolution, thereby forming the work of insole printing and hot pressing. In the working process of this embodiment, the operator can complete the process cycle control with one hand and simultaneously perform the insole replacement operation with the other hand, forming a highly efficient work rhythm of human-machine collaboration. This manual solution driven by the handwheel 5 completely eliminates electric drive, achieving zero-energy operation while ensuring process accuracy. Example
[0042] As attached Figures 7 to 9 As shown, a vertically adjustable pedal 6 is provided below the workbench 1. The adjustment mechanism involves a crossbeam fixed between the two side plates under the workbench 1, with guide holes on both sides of the crossbeam. Second guide posts 61 are fixed to both sides of the pedal 6, each fitting through one of the guide holes in the crossbeam, thus creating a vertical constraint on the pedal 6 relative to the machine base 11. The lifting and lowering of the pedal 6 drives the transmission shaft 31 to rotate. When the pedal 6 descends, it drives the transmission shaft 31 to rotate half a revolution, causing the half-gear 35 to mesh with the first gear 321. When the pedal 6 rises, it drives the transmission shaft 31 to continue rotating half a revolution, causing the drive gear 36 to mesh with the second gear 331.
[0043] Furthermore, the transfer machine in Embodiment 2 also includes a connecting rod assembly, which includes a first connecting rod 71, a second connecting rod 72, a third connecting rod 73, and an eccentric shaft 75. Two eccentric plates 74 are fixed on the drive shaft 31, and the eccentric shaft 75 is fixedly connected between the ends of the two eccentric plates 74 that are offset from the axis of the drive shaft 31, so that the drive shaft 31, the eccentric plates 74, and the eccentric shaft 75 together form a complete crankshaft structure. The lower end of the first connecting rod 71 is pivotally connected to the end of the pedal 6 located within the worktable 1. The two ends of the second connecting rod 72 are pivotally connected to the side plate below the worktable 1 and the upper end of the first connecting rod 71, respectively. The two ends of the third connecting rod 73 are pivotally connected to the middle part of the second connecting rod 72 and the eccentric shaft 75, respectively. In this embodiment, the pivoting structure can be achieved by using pins or bolts to allow the two pivotally connected components to rotate relative to each other. When pedal 6 is pressed, pulling the first link 71 downwards causes the second link 72 to swing downwards. The second link 72, through the third link 73, pulls the eccentric shaft 75 from a high position to a low position, causing the eccentric plate 74 to swing downwards, thus driving the transmission shaft 31 to complete the first half-turn. Afterwards, pedal 6 rises, pushing the first link 71 upwards, causing the second link 72 to swing upwards. The second link 72, through the third link 73, pushes the eccentric shaft 75 from a low position to a high position, causing the eccentric plate 74 to swing upwards, thus driving the transmission shaft 31 to complete the subsequent second half-turn.
[0044] In addition, the pedal 6 is connected to the worktable 1 via a second elastic element 62. The second elastic element 62 provides upward lifting force for the pedal 6. Specifically, the second elastic element 62 can be a tension spring, with its two ends hooked onto the pedal 6 and the crossbeam under the worktable 1, respectively. When the pedal 6 is pressed down, the spring stretches and stores energy. When the pedal 6 is released, the tension spring releases its elastic potential energy to pull the pedal 6 up, creating an automatic upward lifting force. This, in turn, drives the eccentric plate 74 to swing upward, thereby driving the transmission shaft 31 to continue rotating half a revolution. This structure of the second elastic element 62 enables passive driving of the transmission shaft 31's second half revolution, ensuring the continuity of the transmission shaft 31's full revolution.
[0045] It is worth mentioning that when the pedal 6 presses down, driving the eccentric plate 74 to swing downwards until the transmission shaft 31 completes the first half-turn rotation, the eccentric plate 74 swings until its lower end tilts towards the side plate connected to the second connecting rod 72 below the worktable 1. At this time, the direction of the force exerted by the third connecting rod 73 on the eccentric shaft 75 is consistent with the rotation direction of the transmission shaft 31. When the pedal 6 rises, the upward pushing action of the third connecting rod 73 on the eccentric shaft 75 will consequently cause the eccentric plate 74 to continue swinging in the original rotation direction, rather than pushing in the opposite direction. By matching the swing trajectory of the eccentric plate 74 with the direction of the force exerted by the connecting rod, the possibility of reverse rotation is eliminated from the mechanical structure.
[0046] In the operation of the above-described embodiment two, after the insole to be processed is placed on the placement plate 12, pressing the pedal 6 will cause the drive shaft 31 to rotate half a turn, thereby displacing the transfer film 43. Releasing the pedal 6 will cause the drive shaft 31 to rotate another half turn, causing the hot press head 2 to press down and transfer the pattern onto the insole, thus forming the work of insole film positioning and hot pressing. This operation process separates the foot control pedal 6 from the hand handling of picking up and placing the insole, significantly improving operational safety and efficiency. The entire transmission process achieves power distribution and process connection through a purely mechanical structure, forming a semi-automated production mode that conforms to ergonomics.
[0047] In summary, the insole heat transfer machine of this utility model achieves automated operation through the worktable 1, machine base 11, placement plate 12, film placement tray 41, winding tray 42, and transmission assembly 3. The transmission shaft 31 is equipped with a half gear 35 and a drive gear 36. During the first half-cycle rotation, the half gear 35 meshes with the first rotating shaft 32 to drive the winding tray 42 to wind up the transfer film 43, and the synchronous belt 372 moves the cam 34 for pre-positioning. During the second half-cycle rotation, the drive gear 36 meshes with the second rotating shaft 33 to drive the cam 34 to press down the connecting rod 23, forcing the heat pressing head 2 to overcome the resistance of the first elastic element 25 and press down to complete the heat transfer. In the first embodiment, the handwheel 5 drives the transmission shaft 31 to rotate a full circle, and the displacement and heat pressing action of the transfer film 43 are controlled synchronously by one hand. In the second embodiment, the pedal 6 is raised and lowered, and the eccentric shaft 75 is linked by the linkage assembly to drive the transmission shaft 31 to rotate in stages. That is, pressing down the pedal 6 drives the first half-cycle of the transfer film 43 to be positioned, and when the pedal 6 is raised, the second elastic element 62 is reset to drive the second half-cycle of heat pressing. Each embodiment achieves the alternating operation of the transfer film 43 positioning and hot pressing process through the sequential linkage of mechanical components, ensuring the elimination of motion interference and process continuity, while avoiding frequent motor start-stop and aggravating equipment wear.
[0048] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
