Description

Technical Field

[0001] This utility model relates to thermoforming and hot-pressing machinery and equipment. 。 Background Technology

[0002] A thermoforming and hot-pressing machine is a mechanical device used to perform thermoforming and hot-pressing printing on fabrics such as PU, TPU, and microfiber that can be thermoformed or hot-pressed to form textures. It typically includes a work platform, a thermoforming heating module set on the work platform, and a lifting pressure block device mounted on the work platform via a frame.

[0003] The existing operating method of this machine is as follows: First, the printing template is fixedly installed on the vacuum forming heating module. Then, the fabric is manually positioned and covered on the printing template through the positioning structure. Next, a silicone protective sheet is placed on top of the vacuum forming heating module to protect the fabric surface and enhance the heat-pressing texture effect. The vacuum forming heating module starts to draw a vacuum, forming a vacuum composite state between the protective sheet, the fabric, and the upper surface of the vacuum forming heating module. The vacuum forming heating module is then moved to a position directly below the lifting pressure block. Finally, the heat pressing action is initiated, and the lifting pressure block descends, pressing the protective sheet onto the protective sheet. The heat from the vacuum forming heating module, the pressure from the pressure block, and the soft pad layer on the lower surface of the pressure block press against the texture of the printing template, resulting in a texture on the fabric that matches the printing template. After forming, the lifting pressure block rises, releasing the vacuum state of the protective silicone sheet. The vacuum forming heating module is then removed, and the protective sheet and fabric can be taken off.

[0004] In the aforementioned process, the fabric positioning is relatively difficult to pinpoint accurately, requiring manual visual inspection for precise positioning. This process is not easily simplified. However, the operation of the protective silicone sheet can be researched and improved to be non-manual, and manual operation carries risks such as positional deviation, safety hazards, and the possibility of omissions in placing the protective silicone sheet. In view of this, the inventors of this case conducted research and improvements, resulting in this case. Utility Model Content

[0005] The purpose of this invention is to provide an improved fabric thermoforming and printing machine that can save operating procedures and reduce manual intervention.

[0006] To achieve the above objectives, the technical solution of this utility model is: an improved fabric blister heat pressing machine, including a work platform, a blister heating module set on the work platform, and a lifting pressure block device mounted on the work platform via a frame. The lower end of the lifting pressure block device is a pressure block, and the pressure block is provided with a clamping structure for fixing and installing a protective sheet. The clamping structure is configured to unfold the protective sheet so that its upper surface corresponds to the clamping structure below the lower surface of the pressure block.

[0007] The clamping structure is provided with clamping devices on two opposite sides of the pressure block.

[0008] The lowest point of the clamping device is higher than the lower surface of the pressure block in its working state.

[0009] The clamping device is a pressure rod structure that can be adsorbed and connected to the pressure block, or the clamping device is a clamping rod structure set on the pressure block.

[0010] The clamping device is configured to adaptively adjust the height of the lowest point.

[0011] The clamping device includes a fixed clamp fixedly mounted on the pressure block, a fixed upper part that can be removed or clamped onto the fixed clamp, and a swinging lower part connected to the fixed upper part by a hinge structure. A swing limiting structure for limiting the swinging of the swinging lower part is provided between the fixed upper part and the swinging lower part. The swinging lower part is provided with a winding end for the protective plate to pass over it.

[0012] The clamping device includes a fixed block fixedly mounted on the pressure block, a lifting rod that is movably connected to the fixed block via a lifting guide structure and an elastic support component, and a pressure rod that can be adsorbed or fastened to the lifting rod. The pressure rod and the lifting rod are used to clamp the protective sheet.

[0013] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The protective sheet is fixedly installed by a clamping structure on the pressure block. This clamping structure is configured to allow the protective sheet to unfold so that its upper surface corresponds to the clamping structure below the lower surface of the pressure block. Thus, the protective sheet is fixed in place for the working state. During operation, no adjustment is needed for each thermoforming and heat-pressing operation. After the fabric is positioned and aligned with the heat-pressing position, the pressure block can be lowered. Unlike existing mechanical processes, after the fabric is positioned and aligned with the heat-pressing position, the pressure block can be lowered and pressed onto the fabric by the lifting pressure block device, or simultaneously, or when the protective sheet contacts the fabric and the outer thermoforming heating module. The thermoforming heating module then activates vacuum suction, creating a vacuum composite state between the protective sheet, the fabric, and the upper surface of the thermoforming heating module, allowing for continued complete thermoforming and heat-pressing printing. In summary, compared to existing mechanical structures, this significantly reduces the number of steps and manual intervention, thereby achieving the aforementioned objectives.

[0014] The aforementioned further structural design facilitates the installation of the protective plate and avoids the impact of the clamping structure on the normal operation of the mechanical structure. Attached Figure Description

[0026] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0027] This utility model discloses an improved fabric thermoforming and printing machine, such as... Figure 1As shown, the device includes a work platform 1, a vacuum forming heating module 2, and a lifting and pressing block device 3. The work platform 1 is typically a metal frame structure with an outer panel to provide high-strength structural support. The vacuum forming heating module 2 is typically made of a metal material with fast thermal conductivity. The vacuum forming heating module 2, which is set on the work platform 1, typically includes a heating block with a vacuum suction hole 211 structure, a vacuum suction module (not shown in the figure) that forms a vacuum suction system with the vacuum suction hole on the heating block, and a heating unit (not shown in the figure) connected to the heating block 21. The upper surface of the heating block 21 is provided with an imprinting mold 6. To facilitate the positioning operation of the fabric on the imprinting mold 6, the heating block 21 is usually mounted on the work platform 1 by a moving drive mechanism. The lifting and pressing block device 3 is mounted on the working platform 1 via the frame 11. The lifting and pressing block device 3 is typically driven by a drive cylinder, with the lower end of the piston rod of the drive cylinder being a fixedly connected pressing block 31. The main improvement of this utility model is that the pressing block 31 is provided with a clamping structure 5 for fixing and installing the protective sheet 4. The clamping structure 5 is configured to unfold the protective sheet 4 so that the upper surface of the protective sheet 4 corresponds to the lower surface of the pressing block 31, so that the protective sheet 4 can be fully unfolded without shrinking or bulging, ensuring that it can completely cover the fabric and properly cooperate with vacuum suction.

[0028] To ensure ease of use and operation of the clamping structure 5, and to guarantee its stability, effectiveness, and reliability, the clamping structure 5 preferably employs clamping devices on both opposite sides of the pressure block 31 to install the protective sheet 4. This method is simple and provides good results for unfolding and laying the protective sheet 4. Several specific structural configurations are disclosed below with reference to the accompanying drawings.

[0029] like Figure 2 As shown, the clamping device is a pressure rod structure that can be adsorbed onto the pressure block 31. The pressure rod of the pressure rod structure is a long rod, which can flatten one side edge of the protective sheet 4 with a relatively large length. The adsorption can be magnetic adsorption, which simplifies the structure and makes the installation of the protective sheet easy. Alternatively... Figure 3 As shown, the clamping device is a clamping rod structure set on the pressure block 31. The clamping rod of the clamping rod structure is also a long rod, which can flatten one side edge of the protective plate 4 with a large length. The clamping structure can adopt the existing elastic clamping technology structure, which is easily obtained by those skilled in the art. It will not be described in detail here, and it will not affect the clear understanding of the technical solution of this utility model.

[0030] Figure 2 and Figure 3The structure shown allows for quick and efficient unfolding and reliable maintenance of the protective sheet 4 via the long rod 50. In use, the long rod is removed, and the protective sheet 4 is draped over the long rod 50. Thus, when installing the protective sheet 4, only the long rod 50 needs to be removed, and one side of the protective sheet 4 is flatly draped over the corresponding side of the long rod 50 and pressed or clamped down. This completes the operation on one side of the protective sheet 4. Then, the other side of the long rod 50 is removed, and the opposite side of the protective sheet 4 is adjusted to an appropriate position, draped over the long rod 50, and pulled to the corresponding position to press or clamp down. This completes the installation of the protective sheet 4.

[0031] The above are as follows Figure 1 , Figure 2 and Figure 3 The structure shown is configured such that the lowest point of the clamping device is higher than the lower surface of the pressure block 31 in the working state. Since the protective sheet 4 needs to be vacuumed on the vacuum heating module 2 simultaneously with or before the vacuum forming hot pressing, the installation of the protective sheet 4 does not need to be close to the lower surface of the pressure block 31. This avoids mutual interference, which could cause wrinkles on the protective sheet 4, directly affecting the texture of the hot pressing and resulting in defects. Therefore, the protective sheet 4 can also be set with a gap between it and the lower surface of the pressure block 31, so that vacuuming can be done first, followed by pressing. In this regard, the present invention can be further configured to make the clamping device adaptively adjustable in height.

[0032] The structure disclosed in this embodiment is as follows: Figure 4 and Figure 5 As shown, this is a structural setup that enables adaptive adjustment of the lowest point height, such as... Figure 4As shown, the clamping device includes a fixed clamp 51 fixedly mounted on the pressure block 31, a fixed upper part 52 that can be removed or clamped on the fixed clamp 51, and a swinging lower part 53 connected to the fixed upper part 52 by a hinge structure. The fixed upper part 52 and the swinging lower part 53 constitute the aforementioned long rod 50. A swing limiting structure 54 for limiting the swinging lower part 53 is provided between the fixed upper part 52 and the swinging lower part 53. The swinging lower part 53 is provided with a winding end 55 for the protective plate 4 to pass over. When installing the protective plate 4, the fixed upper part 52 is released from the clamp 51 and removed. Then, one side of the protective plate 4 is first wound around the winding end 55 and then around to the upper end of the fixed upper part 52. Then, the fixed upper part 52 is clamped on the fixed clamp 51. The other side is adjusted and clamped in the same way. Thus, under normal conditions, the lower swing parts 55 on both sides are in a drooping state, with their lowest point lower than the lower surface of the pressure block 31. The protective sheet 4 is clearly separated from the lower surface of the pressure block 31. After the pressure block 31 is fully pressed down after the vacuum is drawn, the lowest point of the lower swing parts 53 on both sides will press against the upper surface of the thermoforming heating module 2. At the same time, the mutual force generated will push the lower swing parts 53 upward. Therefore, the lower swing parts 53 will not affect the normal full pressing of the pressure block 31. The above-mentioned swing limiting structure 54 can play a role in pushing and guiding when the mutual force is generated. This structure is simple to set and easy to implement, and its effect is effective and reliable.

[0033] like Figure 5 As shown, the clamping device includes a fixed block 56 fixedly mounted on the pressure block 31, a lifting rod 59 movably connected to the fixed block 56 via a lifting guide structure 57 and an elastic support component 58, and a pressure rod (i.e., the aforementioned long rod 50) that can be adsorbed or fastened to the lifting rod 59. The pressure rod and the lifting rod 59 are used to clamp the protective sheet 4. Figure 4 The structural difference lies in the fact that the fixed block 56 and the lifting rod 59 here are connected by a lifting adjustment mechanism. In this way, under normal conditions, the pressure rods on both sides are pushed down by the elastic support component 58, and their lowest point is lower than the lower surface of the pressure block 31. The tension protective plate 4 is clearly separated from the lower surface of the pressure block 31. After the pressure block 31 is fully pressed down after the vacuum is drawn down, the lowest point of the pressure rods on both sides will abut against the upper surface of the thermoforming heating module 2. At the same time, the mutual force generated will push the lifting rod to compress the elastic support component 58, and under the guidance of the lifting guide structure 57, it will be balanced upward. Therefore, the lifting rod 59 will not affect the normal full pressing down of the pressure block 31. This structure is simple to set up, easy to implement, and effective and reliable.

[0034] In summary, the improved fabric thermoforming and printing machine of this utility model significantly reduces the manual operation steps related to protective sheets compared to existing mechanical structures, thereby reducing human intervention and improving processing efficiency and production benefits, thus achieving the aforementioned objectives.

[0035] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
