AI Technical Summary
In the existing technology, the embossing process of PVC rolls results in poor finished product quality due to uneven temperature and adhesion. In particular, when embossing is performed directly after the surface temperature of the roll has dropped, unevenness and adhesion to the surface of the heating roller are likely to occur.
A PVC roll embossing heating device was designed, which includes a reversing roller and a heating component. Temperature compensation is achieved through the gap between the heating part and the reversing roller, so that the roll is heated to the embossing temperature in a suspended state, avoiding sticking. A lifting and rotating structure is used to adjust the temperature and operating space.
This achieves uniform heating of the roll material, avoids sticking, and ensures the consistency of embossing quality and finished product.

Description
A heating device for embossing PVC rolls Technical Field
[0001] This utility model relates to the field of PVC roll processing, and in particular to a PVC roll embossing and heating device. Background Technology
[0002] Embossing is one step in PVC roll material processing. Generally, after the roll material is formed, the residual heat is used for embossing to obtain the finished product. However, embossing usually occurs at the end of the roll material forming production line. When the PVC roll material reaches this point, its surface temperature has decreased due to prolonged roller transport and there is uneven temperature distribution. If embossing begins directly at this stage, unevenness is likely to occur under the same pressure. Therefore, a heating roller is usually added at this point to raise the roll material back to the embossing temperature. However, after heating, the roll material is prone to sticking to the surface of the heating roller, thus affecting the quality of the finished product. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a PVC roll embossing heating device.
[0004] The present invention is achieved by the following technical solution: a PVC roll embossing and heating device, including a reversing roller and a heating component mounted on a frame, wherein the heating component is located on one side of the reversing roller and there is a gap between the heating component and the reversing roller for the roll to pass through, the roll is wound on the reversing roller and passes through the gap in sequence;
[0005] The heating assembly includes a heating section, which is disposed on the frame and extends downward, and a gap is formed between the heating section and the directional roller for the roll material to pass through sequentially.
[0006] The heating section includes a housing and heating tubes. The heating tubes are arranged at intervals inside the housing and adjacent heating tubes are parallel to each other. The side of the housing where the heating tubes are installed faces the directional roller.
[0007] The heating element is fixed to the frame.
[0008] The heating assembly also includes a lifting part, which is disposed on the frame. The heating part is connected to the lifting part and is driven by the lifting part to move away from or towards the directional roller along the height direction of the frame.
[0009] The lifting unit includes a motor, a lifting shaft, and a lifting rack. The motor is fixed on the frame. One end of the lifting shaft passes through the frame and is fixedly connected to the heating unit. A lifting gear is sleeved on the shaft of the motor. The lifting rack is fixed on the side of the lifting shaft facing the lifting gear and meshes with the lifting gear. The rotation of the lifting gear drives the lifting shaft to reciprocate.
[0010] The heating part is rotatably connected to the lifting part, and the heating assembly also includes a rotating part, which is disposed on the frame and connected to the heating part, driving the heating part to rotate around the lifting part as the center.
[0011] The rotating part includes a rotating motor, a rotating sprocket, and a rotating chain. The rotating motor is fixed on the frame, and the rotating sprocket is sleeved on the shaft of the rotating motor. One end of the rotating chain is fixed to the rotating sprocket and the rotating chain meshes with the rotating sprocket. The other end of the rotating chain is fixedly connected to the heating part. When the rotating sprocket rotates, it drives the heating part to rotate by winding or unwinding the rotating chain.
[0012] There are two directional rollers, which are flush with each other. The outer shell is L-shaped and includes a straight section and a vertical section. The straight section is positioned above the directional rollers, and the vertical section is perpendicular to the straight section and smoothly transitions with it.
[0013] Compared to existing technologies, in actual use, the roll material of this invention is wound around the directional roller, and the actual embossing roller is positioned lower than the directional roller. This requires the roll material to move downwards through the gap. During this movement, it is heated by the heating unit, restoring the roll material to a temperature suitable for embossing. In some embodiments, the relative position of the heating unit and the directional roller can be raised or lowered by a lifting unit. This allows for temperature control by adjusting the distance between the heating unit and the roll material, while also providing ample operating space for replacing easily damaged parts within the heating unit. In some embodiments, the heating unit can not only be raised and lowered but also rotated, providing greater operating space and adjusting the heating area to cover more working conditions. When the heating unit is heating, the roll material is detached from the directional roller and is suspended in the air. Therefore, even if the surface of the roll material softens or melts, it will not adhere, thus ensuring the quality of the embossing. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] Referring to Figures 1-2, a PVC roll embossing heating device includes a reversing roller 1 and a heating assembly 2. The heating assembly 2 is disposed on one side of the reversing roller 1 and has a gap between it and the reversing roller for the roll material to pass through. The roll material is wound around the reversing roller 1 and passes through the gap sequentially. The heating assembly 2 includes a heating section 21, which is disposed on a frame 3 and extends downward. A gap is formed between the heating section 21 and the reversing roller 1 for the roll material to pass through sequentially. The heating section 21 includes a housing 211 and heating tubes 212. The heating tubes 212 are arranged at intervals inside the housing 211, with adjacent heating tubes 212 parallel to each other. The side of the housing 211 where the heating tubes 212 are installed faces the reversing roller 1. Of course, the outer shell 211 of the heating part 21 can be a regular rectangular shell 211 with the middle hollowed out for installing the heating tube 212. The heating tube 212 can be an electric heating device, and the heating tube 212 can be spaced apart and evenly arranged in the cavity.
[0024] Based on the embodiment of the heating unit 21 described above, the heating unit 21 can be directly fixed to the frame 3. In this case, only the outer casing 211 needs to be fixed to the frame 3. The hollowed-out portion of the outer casing 211 faces the directional roller 1, with a gap between them allowing the roll material to pass through. Since the heating pipe 212 is installed inside this hollowed-out portion, the temperature of the roll material can be increased by heating through the heating pipe 212. This provides temperature compensation, allowing the roll material to reach the temperature required for printing. Furthermore, when the heating unit 21 heats the roll material, it is already detached from the directional roller 1 and is in a suspended state. Therefore, even if the surface of the roll material softens or melts, it will not adhere, thus ensuring the quality of the embossing.
[0025] As shown in Figures 1-2, the heating section 21 further includes a second embodiment. In this second embodiment, the outer shell 211 is L-shaped and includes a straight section 2111 and a vertical section 2112. The straight section 2111 is positioned above the directional roller 1, and the vertical section 2112 is perpendicular to and smoothly transitions from the straight section 2111. Both the straight section 2111 and the vertical section 2112 of the outer shell 211 are hollowed out to form cavities for installing the heating pipe 212. The heating pipe 212 installed in the cavity of the straight section 2111 and the heating pipe 212 installed in the vertical section 2112 can both face the directional roller 1 to obtain a larger heating area and thus higher heating efficiency.
[0026] As shown in Figures 3-4, the heating section 21 may not be directly fixed to the frame 3. Specifically, the heating assembly 2 also includes a lifting section 22, which is mounted on the frame 3. The heating section 21 is connected to the lifting section 22 and is driven by the lifting section 22 to move away from or towards the directional roller 1 along the height direction of the frame 3. In this embodiment, the heating section 21 can adopt the first embodiment of the heating section 21 to avoid interference in the stroke.
[0027] The lifting unit 22 in this application includes a motor 221, a lifting shaft 222, and a lifting rack 223. The motor 221 is fixed on the frame 3. One end of the lifting shaft 222 passes through the frame 3 and is fixedly connected to the heating unit 21. A lifting gear is sleeved on the shaft of the motor 221. The lifting rack 223 is fixed on the side of the lifting shaft 222 facing the lifting gear and meshes with the lifting gear. The rotation of the lifting gear drives the lifting shaft 222 to move back and forth.
[0028] As shown in Figures 5-6, the heating section 21 can be raised and lowered, and it can also rotate. Specifically, the heating section 21 is rotatably connected to the lifting section 22. The heating assembly 2 also includes a rotating section 23, which is mounted on the frame 3 and connected to the heating section 21, driving the heating section 21 to rotate around the lifting section 22. The rotating section 23 is fixed on the frame 3 to drive the heating section 21 to rotate around the lifting section 22. The rotating section 23 includes a rotating motor, a rotating sprocket 231, and a rotating chain 232. The rotating motor is fixed on the frame 3, and the rotating sprocket 231 is sleeved on the shaft of the rotating motor. One end of the rotating chain 232 is fixed to the rotating sprocket 231, and the rotating chain 232 meshes with the rotating sprocket 231. The other end of the rotating chain 232 is fixedly connected to the heating section 21. When the rotating sprocket 231 rotates, it drives the heating section 21 to rotate by winding or unwinding the rotating chain 232. In this embodiment, the heating unit 21 can be implemented in either the first or second manner. The rotating chain 232 only needs to be fixed to the outer shell 211 of the corresponding heating unit 21. Referring to Figure 7, when the heating unit 21 rotates, it flips around the frame 3 under the drive of the chain.
[0029] In this application, there are two directional rollers 1, which are flush with each other. In the second embodiment using the heating section 21, the outer shell 211 of the heating section 21 is L-shaped, comprising a straight section 2111 and a vertical section 2112. The straight section 2111 is positioned above the directional rollers 1, and the vertical section 2112 is perpendicular to and smoothly transitions from the straight section 2111. This results in a larger heating area and higher heating efficiency.
[0030] Compared to existing technologies, in actual use, the roll material of this invention is wound around the directional roller 1, and the actual embossing roller is positioned at a height lower than the directional roller 1. This requires the roll material to pass through the gap and move downwards. During this movement, it is heated by the heating unit 21, allowing the roll material to return to a temperature suitable for embossing. In some embodiments, the relative position of the heating unit 21 and the directional roller 1 can be raised or lowered by the lifting unit 22. This allows for temperature control by adjusting the distance between the heating unit 21 and the roll material, while also providing sufficient operating space for replacing easily damaged parts within the heating unit 21. In some embodiments, the heating unit 21 can not only be raised and lowered but also rotated, providing a larger operating space and allowing for adjustment of the heating area to cover more working conditions.
[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
