Description

Technical Field

[0001] This invention relates to a hot melt machine for producing protective fabrics, specifically a double-sided heating hot melt machine. Background Technology

[0002] A hot melt laminating machine is a processing machine that uses heat radiation to heat-melt and bond plastics, sheets, fabrics, etc., combining two or more different materials and applying a certain pressure to make them composite into one. In the garment processing industry, hot melt laminating machines (hot melt bonding machines) are commonly used to heat-press and bond fabrics. The working principle of a hot melt laminating machine is as follows: Two rollers are placed close together, one of which has a heating function and the other has a pressing function. The two fabric materials to be laminated are passed through the gap between the two rollers. Hot melt adhesive particles are evenly distributed on the contact surfaces of the two layers of fabric. As the two fabric materials pass through the gap between the rollers, the hot melt adhesive melts and is pressed, causing the fabrics to stick together.

[0003] For example, the utility model patent application with authorization announcement number CN211105707U and titled "A Hot Melt Machine for the Production of Composite Material Protective Fabric" includes a base plate. A support plate is fixedly connected to one end of the top of the base plate. Two circular through holes are drilled at one end of the top of the support plate. Two fixed shafts are fixedly connected to one end of the top of the base plate, with corresponding through holes extending through the tops of the two fixed shafts. A roller is fitted around the outside of each fixed shaft. A hot melt wheel is rotatably connected between the top of the base plate and the bottom of the support plate, located on one side of the fixed shafts. Slide grooves are drilled on the top of both the base plate and the top of the support plate, located on one side of the hot melt wheel. Rolling rollers are slidably connected inside the slide grooves. Limit plates are fixedly connected to both ends of the central shaft of the rolling rollers, which pass through the slide grooves. During use, hot melt adhesive particles are evenly distributed on both surfaces. The composite protective fabrics are wound onto the outside of a roll. The roll is then passed through a through hole and fitted onto the outside of a fixed shaft. The two types of protective fabrics are then passed between a hot melt wheel and a rolling wheel, with one end fixed together. They are then fixed onto a storage cylinder, ensuring that the hot melt adhesive particles of the two protective fabrics are tightly adhered to each other. The equipment is then powered on, and the control panel controls the operation of the internal heating structure of the hot melt wheel. Simultaneously, the control panel controls the operation of the first servo motor, which drives the drive gear to rotate. This, in turn, drives the right-end storage cylinder to rotate via the driven gear, winding up the two types of protective fabrics. As the protective fabrics pass between the hot melt wheel and the rolling wheel, they are heated by the hot melt wheel, causing the hot melt adhesive particles to melt and be compressed, thus bonding and laminating the fabrics. Finally, the bonded and laminated protective fabrics are wound up.

[0004] In existing hot melt machines, the following problems exist when the hot melt roller heats two fabrics of different materials: First, because one hot melt roller is needed to heat two fabrics, one fabric is in direct contact with the roller while the other does not, transferring heat through the fabric itself. This leads to inconsistent temperatures between the two fabrics, affecting the bonding and lamination of the fabrics. Second, existing hot melt machines perform heating and rolling simultaneously, making it difficult to control the temperature of the heated fabrics, often resulting in uneven bonding. The phenomenon of heating the materials at too high or too low temperatures can lead to several problems. When the fabric is heated to a lower temperature, the adhesion between the two fabrics will be poor. Conversely, when the fabric is heated to a higher temperature, the hot melt adhesive particles in the fabric will melt more rapidly. As a result, during the rolling process, the hot melt adhesive between the two fabrics can easily be squeezed out from both sides of the fabric and drip onto the rolling roller or hot melt roller. During the continuous compounding and extrusion process, subsequent fabrics will come into contact with the hot melt adhesive on the rolling roller or hot melt roller, which will contaminate the fabric and negatively impact its production and subsequent use. Summary of the Invention

[0005] The purpose of this invention is to provide a double-sided heating hot melt machine to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A double-sided heating hot melt machine includes a frame, the frame including a base and two side mounting plates disposed on the base. The two side mounting plates are sequentially arranged with a raw material roll, a guiding mechanism, a rolling mechanism, and a winding mechanism along the conveying direction of the processed fabric. The rolling mechanism includes a drive unit and an upper rolling roller and a lower rolling roller disposed opposite to each other. The upper rolling roller and the lower rolling roller are both drively connected to the drive unit. A rolling gap is preset between the upper rolling roller and the lower rolling roller for the processed fabric to pass through. The machine also includes a heating mechanism disposed between the guiding mechanism and the rolling mechanism. The heating mechanism includes an upper heating element and a lower heating element disposed opposite to each other, with a heating gap formed between the upper heating element and the lower heating element.

[0008] The aforementioned double-sided heating hot melt machine includes a guide mechanism comprising guide rollers, which are arranged in a one-to-one correspondence with the raw material roll.

[0009] The aforementioned double-sided heating hot melt machine also includes a temperature measuring element, which is disposed between the rolling mechanism and the heating mechanism, for detecting the temperature of the processed fabric conveyed to the roller mechanism.

[0010] The aforementioned double-sided heating hot melt machine further includes an adjusting mounting component, on which both the upper heating element and the lower heating element are mounted.

[0011] In the aforementioned double-sided heating hot melt machine, the adjusting mounting component is adjustablely mounted on the frame, and the adjusting mounting component can adjust the position of the upper heating component and the lower heating component by moving along the frame.

[0012] The aforementioned double-sided heating hot melt machine also includes a heating compensation mechanism, which includes an upper compensation component and a lower compensation component. The upper compensation component is correspondingly arranged with respect to the upper heating element, and the lower compensation component is correspondingly arranged with respect to the lower heating element.

[0013] The aforementioned double-sided heating hot melt machine includes an upper compensation component comprising an upper arc-shaped compensation cover and an upper arc-shaped heat insulation cover. The upper arc-shaped compensation cover is disposed on the fabric inlet side of the upper heating element, and the upper arc-shaped heat insulation cover is disposed on the fabric outlet side of the upper heating element.

[0014] The aforementioned double-sided heating hot melt machine includes a lower compensation component comprising a lower arc-shaped compensation cover and a lower arc-shaped heat insulation cover. The lower arc-shaped compensation cover is disposed on the fabric inlet side of the lower heating element, and the lower arc-shaped heat insulation cover is disposed on the fabric outlet side of the lower heating element.

[0015] The aforementioned double-sided heating hot melt machine further includes an upper compensation component and a lower compensation component, wherein the upper arc-shaped compensation cover, the upper arc-shaped insulation cover, the lower arc-shaped compensation cover, and the lower arc-shaped insulation cover are rotatably mounted on the mounting component.

[0016] The aforementioned double-sided heating hot melt machine also includes an adjusting component in its heating compensation mechanism. The upper arc-shaped compensation cover, upper arc-shaped heat preservation cover, lower arc-shaped compensation cover, and lower arc-shaped heat preservation cover are rotatable under the drive of the adjusting component to adjust their compensation angles.

[0017] The beneficial effects of the present invention are as follows: The double-sided heating hot melt machine provided by the present invention includes a base and two side mounting plates disposed on the base. The two side mounting plates are sequentially arranged with a raw material roll, a guiding mechanism, a heating mechanism, a rolling mechanism and a winding mechanism along the conveying direction of the processed fabric. The heating mechanism includes an upper heating element and a lower heating element disposed opposite to each other, forming a heating gap between the upper heating element and the lower heating element. The upper heating element and the lower heating element can heat the processed fabric conveyed from the heating gap, so that both sides of the processed fabric can be heated. In this way, the two types of processed fabric are heated evenly. At the same time, the heating mechanism and the rolling mechanism are separate, so that the temperature of the heated fabric can be adjusted, so that the temperature of the heated fabric when it is conveyed to the rolling mechanism is appropriate, and the temperature is avoided from being too high, causing the hot melt adhesive to be squeezed and dripped onto the rolling mechanism.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 13 The present invention will now be described in further detail.

[0035] This invention provides a double-sided heating hot melt machine, including a frame 1. The frame 1 includes a base 10 and two side mounting plates 11 disposed on the base 10. The two side mounting plates 11 are sequentially arranged along the conveying direction of the processed fabric, including a raw material roll 2, a guiding mechanism 33, a rolling mechanism 5, and a winding mechanism 8. The rolling mechanism 5 includes a driving unit 43 and an upper rolling roller 50 and a lower rolling roller 51 disposed opposite to each other. The upper rolling roller 50 and the lower rolling roller 51 are both connected to the driving unit 43. A rolling gap 52 for the processed fabric to pass through is preset between the upper rolling roller 50 and the lower rolling roller 51. The machine also includes a heating mechanism 4, which is disposed between the guiding mechanism 3 and the rolling mechanism 5. The heating mechanism 4 includes an upper heating element 40 and a lower heating element 41 disposed opposite to each other, with a heating gap 42 formed between the upper heating element 40 and the lower heating element 41.

[0036] Specifically, the hot melt machine includes a frame 1 for mounting the equipment. The frame 1 includes a base 10 and two side mounting plates 11 mounted on the base 10. The two side mounting plates 11 are arranged in parallel with a certain distance between them. This distance is greater than the width of the fabric being processed. Along the conveying direction of the fabric being processed, a raw material roll 2, a guiding mechanism 3, a heating mechanism 4, a rolling mechanism 5, and a winding mechanism 8 are arranged sequentially on the two side mounting plates 11. The types of fabric being processed can be two, three, or more. This embodiment takes two types of fabric being processed as an example. When there are three or more types of fabric being processed, the number of raw material roll 2, guiding mechanism 3, and heating mechanism 4 can be adjusted as needed to meet the processing requirements.

[0037] In this embodiment, the raw material roll 2 is used for winding and conveying the processed fabric. There are two raw material rolls 2, which are referred to as the upper roll 20 and the lower roll 21 for ease of description. Both ends of the upper roll 20 and the lower roll 21 are rotatably mounted on the side mounting plate 11. The first processed fabric and the second processed fabric, on which hot melt adhesive particles are evenly distributed on the surface, are wound around the outer sides of the upper roll 20 and the lower roll 21, respectively. The guide assembly 3 is used to guide and convey the processed fabric. The guide assembly 3 includes an upper guide roller 30 and a lower guide roller 31. The guide roller 31, the upper guide roller 30 and the lower guide roller 31 are also rotatably mounted on the side mounting plate 11. The distance between the upper drum 20 and the lower drum 21 is the feeding distance. The upper guide roller 30 and the lower guide roller 31 form a guide distance. The guide distance is smaller than the feeding distance, so that the processed fabric can be smoothly conveyed to the heating mechanism 4 and the rolling mechanism 5. In order to realize the conveying of the processed fabric, other conveying structures for conveying the processed fabric can also be set on the frame 1. This is the prior art and will not be described in detail.

[0038] In this embodiment, the heating mechanism 4 is used to heat the processed fabric. The heating mechanism 4 includes an upper heating element 40 and a lower heating element 41 arranged opposite to each other. The upper heating element 40 and the lower heating element 41 can be cylindrical, plate-shaped, etc. Heating structures are installed inside the upper heating element 40 and the lower heating element 41, and a heating gap 42 is formed between the upper heating element 40 and the lower heating element 41. During the processing, the processed fabric will pass through the heating gap 42, so the upper heating element 40 and the lower heating element 41 will heat the processed fabric passing through it. For ease of description... The two processed fabrics are referred to as the first processed fabric and the second processed fabric, respectively. The first processed fabric is located above the second processed fabric. Thus, the upper heating element 40 is located directly above the first processed fabric, and the lower heating element 41 is located directly below the second processed fabric. The guide component 3 ensures that the distance between the first processed fabric and the upper heating element 40 and the distance between the second processed fabric and the lower heating element 41 are the same. In this way, the heating mechanism 4 can heat both sides of the processed fabric, so that the first processed fabric and the second processed fabric are heated evenly.

[0039] In this embodiment, the rolling mechanism 5 is used to roll and bond two types of processed fabrics to form the desired fabric. The rolling mechanism 5 includes a drive unit 43 and an upper rolling roller 50 and a lower rolling roller 51 arranged opposite to each other. A rolling gap 52 is preset between the upper rolling roller 50 and the lower rolling roller 51 for the processed fabric to pass through. The rolling gap 52 is set to correspond to the thickness of the processed fabric. Both the upper rolling roller 50 and the lower rolling roller 51 are driven by the drive unit 43. The drive unit 43 enables the upper rolling roller 50 and the lower rolling roller 51 to be driven together. The lower roller 51 rotates, and the upper roller 50 and the lower roller 51 rotate in different directions. Thus, the two types of processed fabrics are heated by the heating mechanism 4 and then conveyed to the rolling gap 52. The upper roller 50 and the lower roller 51 roll the two types of processed fabrics, so that the two types of processed fabrics are rolled and bonded to form the required processed fabric. The winding mechanism 8 includes a driving component 80 and a winding cylinder 81 connected to the driving component 80. The rotation of the winding cylinder 81 can wind up the processed fabric that has been rolled and bonded.

[0040] This invention provides a double-sided heating hot melt machine. The frame 1 includes a base 10 and two side mounting plates 11 disposed on the base 10. The two side mounting plates 11 are sequentially arranged along the conveying direction of the processed fabric as a raw material roll 2, a guiding mechanism 3, a heating mechanism 4, a rolling mechanism 5, and a winding mechanism 8. The heating mechanism 4 includes an upper heating element 40 and a lower heating element 41 disposed opposite to each other, forming a heating gap 42 between the upper heating element 40 and the lower heating element 41. The upper heating element 40 and the lower heating element 41 can heat the processed fabric conveyed from the heating gap 42, so that both sides of the processed fabric can be heated. In this way, the two types of processed fabric are heated evenly. At the same time, the heating mechanism 4 and the rolling mechanism 5 are separate, so that the temperature of the heated fabric can be adjusted, so that the temperature of the heated fabric when it is conveyed to the rolling mechanism 5 is appropriate, and the temperature is not too high, so that the hot melt adhesive is squeezed and dripped onto the rolling mechanism 5.

[0041] In the embodiments provided by the present invention, preferably, a temperature measuring element 15 is also included, which is disposed between the rolling mechanism 5 and the heating mechanism 4, for detecting the temperature of the processed fabric conveyed to the roller mechanism. This ensures that the temperature of the processed fabric conveyed to the rolling mechanism 5 meets the requirements, avoids the situation where the hot melt adhesive is squeezed out due to excessively high processing fabric temperature, and also avoids the situation where the adhesive effect is poor due to excessively low processing fabric temperature.

[0042] During use, due to differences in processing stages and fabric materials, the temperature of the fabric conveyed to the rolling mechanism 5 varies, often resulting in excessively high or low fabric temperatures. Therefore, the heating mechanism 4 needs adjustment to ensure the fabric is heated to a suitable temperature. A temperature adjustment gap is formed between the heating mechanism 4 and the rolling mechanism 5. By adjusting the size of this gap, the temperature of the fabric conveyed to the rolling mechanism 5 can be regulated. In this embodiment, the heating mechanism 4 also includes an adjusting mounting component 44. Both the upper heating element 40 and the lower heating element 41 are mounted on the adjusting mounting component 44, which is adjustablely mounted on the frame 1. The adjusting mounting component 44 can move horizontally along the frame 1 to adjust the size of the temperature adjustment gap. Specifically, when the temperature sensor detects that the temperature of the processed fabric is high, the adjusting mounting component 44 is adjusted to the first working position, which is farther away from the rolling assembly. At this time, the distance between the heating mechanism 4 and the rolling mechanism 5 is large, which can form a large temperature adjustment gap and reduce the temperature of the processed fabric when it is conveyed to the rolling mechanism 5. Conversely, when the temperature sensor detects that the temperature of the processed fabric is low, the adjusting mounting component 44 is adjusted to the second working position, which is closer to the rolling assembly. At this time, the temperature adjustment gap between the heating mechanism 4 and the rolling mechanism 5 is small, which avoids the loss of heat from the processed fabric.

[0043] In the embodiments provided by the present invention, optionally, the adjusting mounting component 44 includes a left moving plate 440 and a right moving plate 441 arranged opposite to each other. The two ends of the upper heating component 40 and the lower heating component 41 are respectively fixed on the left moving plate 440 and the right moving plate 441. A sliding seat 442 is provided on both the left moving plate 440 and the right moving plate 441. A horizontal sliding groove 110 is provided on the side mounting plate 11. The sliding seat 442 is slidably connected in the horizontal sliding groove 110. A driving component is provided on the frame 1 to drive the sliding seat 442. The driving component can drive the sliding seat 442 to move along the horizontal sliding groove 110, so that the temperature adjustment distance between the heating mechanism 4 and the rolling mechanism 5 can be adjusted as needed.

[0044] In actual use, the upper heating element 40 and the lower heating element 41 are often affected by ambient temperature and air flow, causing the heat loss of the upper heating element 40 and the lower heating element 41 to be uncontrolled. It is difficult to guarantee the temperature of the processed fabric, resulting in the processed fabric having a low temperature. As a result, it is difficult to ensure the stability of the processed fabric. In addition to adjusting the position of the heating mechanism 4, another embodiment of the present invention also provides a heating compensation mechanism 6. The heating compensation mechanism 6 is set corresponding to the heating mechanism 4. The heating compensation component can reduce the heat loss of the upper heating element 40 and the lower heating element 41, and improve the heating effect and heating stability of the heating mechanism 4 on the processed fabric.

[0045] In another embodiment of the present invention, preferably, the heating compensation mechanism 6 includes an upper compensation component 60 and a lower compensation component 61 disposed opposite to each other. The upper compensation component 60 includes an upper arc-shaped compensation cover 600 and an upper arc-shaped heat insulation cover 601. The upper arc-shaped compensation cover 600 is disposed on the fabric-entry side of the upper heating element 40, and the upper arc-shaped heat insulation cover 601 is disposed on the fabric-exit side of the upper heating element 40. The lower compensation component 61 has the same structure as the upper compensation component 60. The lower compensation component 61 includes a lower arc-shaped compensation cover 610 and a lower arc-shaped heat insulation cover 611. The lower arc-shaped compensation cover 610 is disposed on the fabric-entry side of the lower heating element 41, and the lower arc-shaped heat insulation cover 611 is disposed on the fabric-entry side of the lower heating element 41. On the fabric outlet side of 1, heating elements are provided inside the upper arc-shaped compensation cover 600 and the lower arc-shaped compensation cover 610. The heating elements can be heating tubes. The upper arc-shaped compensation cover 600 and the lower arc-shaped compensation cover 610 are both arc-shaped reflectors with high gloss, which can fully reflect the heat scattered by the heating tube and evenly apply the heat to the upper heating element 40, the lower heating element 41 or the heating gap 42 after reflection. It can provide heat compensation to the surface of the upper heating element 40 and the lower heating element 41, and can also heat the processed fabric located in the heating gap 42. The upper arc-shaped heat preservation cover 601 and the lower arc-shaped heat preservation cover 611 are arc-shaped covers, which are made of heat preservation materials.

[0046] In another embodiment of the present invention, preferably, both the upper compensation component 60 and the lower compensation component 61 include a mounting component 62 and an adjusting component. The mounting component 62 includes a mounting beam 620, and at least one set of mounting brackets 621 are fixedly provided on the mounting beam 620. Rotary connection structures are provided on opposite sides of the mounting brackets 621, and the rotary connection structures include two connecting holes 622. At least one set of arc-shaped mounting strips 63 are provided on the upper arc-shaped compensation cover 600, the upper arc-shaped insulation cover 601, the lower arc-shaped compensation cover 610, and the lower arc-shaped insulation cover 611. The number of sets of arc-shaped mounting strips 63 is consistent with the number of mounting brackets 621. Each set of arc-shaped mounting strips 63 has two strips. A first rotary mounting hole is provided on the side of the arc-shaped mounting strip 63 closest to the mounting beam 620. A second rotating mounting hole is provided in the middle position. A first rotating mounting shaft 630 is provided on the first rotating mounting hole of the two arc-shaped mounting strips 63. The first rotating mounting shaft 630 is rotatably mounted on the two connecting holes 622. A second rotating mounting shaft 631 is provided on the second rotating mounting hole of the two arc-shaped mounting strips 63. The second rotating mounting shaft 631 is connected to the adjusting component. The adjusting component can drive the second rotating mounting shaft 631, so that the upper arc-shaped compensation cover 600, the upper arc-shaped heat insulation cover 601, the lower arc-shaped compensation cover 610, and the lower arc-shaped heat insulation cover 611 can rotate about the first rotating mounting shaft 630 as the rotation axis, thereby adjusting the angle of the upper arc-shaped compensation cover 600, the upper arc-shaped heat insulation cover 601, the lower arc-shaped compensation cover 610, and the lower arc-shaped heat insulation cover 611.

[0047] In another embodiment of the present invention, preferably, the adjusting component includes a lifting adjusting plate 64, with rotating connecting members 65 respectively provided on both opposite sides of the lifting adjusting plate 64. The number of lifting adjusting plates 64 is consistent with the number of mounting brackets 621, and the lifting adjusting plates 64 and mounting brackets 621 are arranged in a one-to-one correspondence. Rotating connecting members 65 are provided on both sides of the lifting adjusting plate 64, and each rotating connecting member 65 includes two rotating plates. The rotating plates are rotatably connected to the lifting adjusting plate 64 via a rotating connecting shaft. The lower ends of the two rotating plates are connected to a second rotating mounting shaft 631, and each lifting adjusting plate 64 is connected via a drive rod 66. If the above compensation component 60 includes two mounting brackets 621, then the upper arc-shaped compensation cover 600... Both the upper arc-shaped heat insulation cover 601 and the upper arc-shaped heat insulation cover 601 are equipped with two sets of arc-shaped mounting strips 63. There are also two lifting adjustment plates 64 and two rotating connectors 65. The first rotating mounting shaft 630 of the two sets of arc-shaped mounting strips 63 is connected to the connecting hole 622 of the mounting bracket 621, and the second rotating mounting shaft 631 of the two sets of arc-shaped mounting strips 63 is connected to the rotating connector 65. The drive rod 66 is connected to both lifting plates. Since the mounting bracket 621 is fixedly mounted on the mounting beam 620, and both ends of the mounting beam 620 are fixedly connected to the left moving plate 440 and the right moving plate 441 respectively, the left moving plate 440 and the right moving plate 441 are slidably connected in the horizontal sliding groove 110 through the sliding seat 442. The upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 are also equipped with two sets of arc-shaped mounting strips 63. The heat insulation cover 601, the lower arc-shaped compensation cover 610, and the lower arc-shaped heat insulation cover 611 are rotatably connected to the mounting bracket 621 via the arc-shaped mounting strip 63 and the first rotating mounting shaft 630, respectively. When the drive rod 66 moves up and down, the left moving plate 440, the right moving plate 441, and the sliding seat 442 are restricted and cannot move up and down. Thus, the drive rod 66 drives the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 to rotate via the rotating connector 65, the second rotating mounting shaft 631, and the first rotating mounting shaft 630, thereby allowing the angles of the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 to be adjusted. The structure of the lower compensation component 61 is the same as that of the upper compensation component 60 in terms of structure and adjustment drive method, and will not be described in detail. At the same time, the upper... The number of mounting brackets 621, mounting components 62, and adjusting parts on the arc-shaped compensation cover 600, upper arc-shaped insulation cover 601, lower arc-shaped compensation cover 610, and lower arc-shaped insulation cover 611 can be set according to their length. At the same time, in order to facilitate the rotation of the upper arc-shaped compensation cover 600, upper arc-shaped insulation cover 601, lower arc-shaped compensation cover 610, and lower arc-shaped insulation cover 611, arc-shaped edges corresponding to the rotation stroke of the upper arc-shaped compensation cover 600, upper arc-shaped insulation cover 601, lower arc-shaped compensation cover 610, and lower arc-shaped insulation cover 611 are provided on both sides of the mounting bracket 621 and the mounting beam 620 to avoid obstructing the rotation of the upper arc-shaped compensation cover 600, upper arc-shaped insulation cover 601, lower arc-shaped compensation cover 610, and lower arc-shaped insulation cover 611.

[0048] The upper arc-shaped compensation cover 600, upper arc-shaped heat insulation cover 601, lower arc-shaped compensation cover 610, and lower arc-shaped heat insulation cover 611 can be adjusted as needed during use. A preferred configuration is as follows: when the first heating element and the second heating element are adjusted to a first working position that is far from the rolling assembly, the temperature adjustment distance between the heating mechanism 4 and the rolling mechanism 5 is at its maximum, and the included angle between the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 is at its maximum (the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 can be rotated). When the lower arc-shaped compensation cover 610 and the lower arc-shaped heat insulation cover 611 are rotated to a near-horizontal state, the included angle between them is also the largest (the lower arc-shaped compensation cover 610 and the lower arc-shaped heat insulation cover 611 can also be rotated to a near-horizontal state). At this time, the upper arc-shaped compensation cover 600 and the lower arc-shaped compensation cover 610 are not working, and the heat insulation effect of the upper arc-shaped heat insulation cover 601 and the lower arc-shaped heat insulation cover 611 is also the worst. The temperature of the processed fabric conveyed can be reduced by heating the conveyed processed fabric to the rolling mechanism 5 only through the upper heating element 40 and the lower heating element 41.

[0049] When the first and second heating elements are adjusted to the second working position, which is far from the rolling assembly, the temperature adjustment gap between the heating mechanism 4 and the rolling mechanism 5 is at its minimum, the included angle between the upper arc-shaped compensation cover 600 and the upper arc-shaped heat preservation cover 601 is also at its minimum, and the included angle between the lower arc-shaped compensation cover 610 and the lower arc-shaped heat preservation cover 611 is also at its minimum. In this way, the upper arc-shaped compensation cover 600 and the upper arc-shaped heat preservation cover 601 can achieve the compensation and heat preservation effect on both sides of the upper heating element 40, and the lower arc-shaped compensation cover 610 and the lower arc-shaped heat preservation cover 611 can achieve the compensation and heat preservation effect on both sides of the lower heating element 41, thereby improving the heating effect on the processed fabric.

[0050] In another embodiment of the present invention, an upper guide groove 111 and a lower guide groove 112 are further provided on the side mounting plate 11. The upper guide groove 111 and the lower guide groove 112 are symmetrically arranged on the side mounting plate 11. The guide groove is an inclined groove. From the direction of the guiding mechanism 3 to the rolling mechanism 5, the height of the upper guide groove 111 gradually increases and the height of the lower guide groove 112 gradually decreases. Sliding members 660 are provided at both ends of the drive rod 66. The sliding members 660 at both ends of the drive rod 66 of the upper compensation component 60 are respectively slidably restricted in the upper guide groove 111, and the sliding members 660 at both ends of the drive rod 66 of the lower compensation component 61 are respectively slidably restricted in the upper guide groove 111. The sliding members 660 are respectively slidably restricted in the lower guide groove 112. Thus, when the driving member drives the sliding seat 442 to move from the second working position to the first working position along the horizontal sliding groove 110, the sliding members 660 at both ends of the driving rod 66 of the upper compensation component 60 gradually move upward along the upper guide groove 111, correspondingly driving the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 to rotate so that their included angle gradually decreases. The sliding members 660 at both ends of the driving rod 66 of the lower compensation component 61 gradually move downward along the lower guide groove 112, correspondingly driving the lower arc-shaped compensation cover 610 and the lower arc-shaped heat insulation cover 611 to rotate so that their included angle gradually decreases.

[0051] When the driving component drives the sliding seat 442 to move from the first working position to the second working position along the horizontal sliding groove 110, the sliding parts 660 at both ends of the upper compensation component 60 drive the rod 66 to gradually move downward along the upper guide groove 111, correspondingly driving the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 to rotate so that their included angle gradually increases. The sliding parts 660 at both ends of the lower compensation component 61 drive the rod 66 to gradually move upward along the lower guide groove 112, correspondingly driving the lower arc-shaped compensation cover 610 and the lower arc-shaped heat insulation cover 611 to rotate so that their included angle gradually increases.

[0052] During use, a certain heating distance is preset between the upper heating element 40 and the first processed fabric, and between the lower heating element 41 and the second processed fabric. In another embodiment provided by the present invention, the upper heating element 40 and the lower heating element 41 are set to be adjustable, so that the heating distance can be adjusted as needed. The upper heating element 40 and the lower heating element 41 have the same structure. Taking the upper heating element 40 as an example, the upper heating element 40 includes an inner cylindrical body 70 and an annular heating body 45 surrounding the inner cylindrical body 70. The annular heating body 45 is coaxially arranged with the inner cylindrical body 70. An annular cavity 71 with an annular cross section is formed between the annular heating body 45 and the inner cylindrical body 70. The annular heating body 45 is formed by combining multiple arc-shaped heating plates 46. The arc-shaped heating plates 46 are arranged sequentially along the circumference of the inner cylindrical body 70 to form the annular heating body 45. A heating structure is provided inside the arc-shaped heating plate 46. The inner and outer surfaces of the arc-shaped heating plate 46 are made of heat-conducting material so as to conduct heat.

[0053] In another embodiment of the present invention, preferably, a spreading adjustment component 7 is further provided in the annular cavity 71. The spreading adjustment component 7 is disposed between the inner cylindrical body 70 and the arc-shaped heating plate 46. The spreading adjustment component 7 can drive the arc-shaped heating plate 46, thereby adjusting the distance between the arc-shaped heating plate 46 and the inner cylindrical body 70. When the arc-shaped heating plate 46 is driven to move away from the center of the inner cylindrical body 70, the heating distance between the arc-shaped heating plate 46 and the first processed fabric decreases. When the arc-shaped heating plate 46 is adjusted to the maximum distance from the center of the cylindrical body, the arc-shaped heating plate 46 contacts the first processed fabric. When the arc-shaped heating plate 46 is driven to move closer to the center of the inner cylindrical body 70, the heating distance between the arc-shaped heating plate 46 and the first processed fabric increases.

[0054] In another embodiment of the present invention, preferably, the expansion adjustment component 7 includes an annular mounting body 72, which is externally connected to the inner cylindrical body 70. A waist-shaped groove 720 is provided on the annular mounting body 72. A rotary drive block 700 is provided on the inner cylindrical body 70, located within the waist-shaped groove 720. An expansion connector 73 is connected to the rotary connecting block 460. A rotary connecting block 460 is provided on the inner side of the arc-shaped heating plate 46. One end of the expansion connector 73 is rotatably connected to the rotary drive block 700, and the other end is connected to the rotary connecting block 700. The rotating drive block 700, the spreading connector 73, and the rotating connecting block 460 are connected in sequence to form a linkage drive component 74. Multiple sets of linkage drive components 74 are provided on the inner cylindrical body 70. The multiple sets of linkage drive components 74 are arranged at intervals along the axial direction of the inner cylindrical body 70, and the number of each set of linkage drive components 74 can be consistent with the number of arc heating plates 46. Thus, when the inner cylindrical body 70 moves along the axial direction of the annular mounting body 72, the arc heating plates 46 are driven to move away from or closer to the center of the inner cylindrical body 70.

[0055] In another embodiment of the present invention, a housing 12 is further provided on the side mounting plate 11, and a trapezoidal driving block 13 is provided on the housing 12. The trapezoidal driving block 13 is a right trapezoid, and an inclined driving groove 14 is provided on the inclined surface of the trapezoidal driving block 13. Sealing plates are provided at both ends of the annular mounting body 72. Through holes are provided on both the sealing plates and the sliding seat 442. A pressing motion rod 76 is provided at one end of the inner cylindrical body 70. The end of the pressing motion rod 76 passes through the through holes of the sealing plates and the sliding seat 442 and is connected to a pressing block 75. The pressing block 75 is slidably restricted in the inclined driving groove 14. Thus, when the driving member drives the sliding seat 442 to move along the horizontal sliding groove 110, it moves from the second working position to the first working position. When the device is in motion, the pressing block 75 moves along the inclined driving groove 14, driving the inner cylindrical body 70, causing the inner cylindrical body 70 to move along the axial direction of the annular mounting body 72. When the arc-shaped heating plate 46 is driven to move away from the center of the inner cylindrical body 70, the heating distance between the arc-shaped heating plate 46 and the first processed fabric decreases. Conversely, when the driving member drives the sliding seat 442 to move along the horizontal sliding groove 110 from the first working position to the second working position, the pressing block 75 moves along the inclined driving groove 14, and the inner cylindrical body 70 moves along the axial direction of the annular mounting body 72, thereby causing the arc-shaped heating plate 46 to move closer to the center of the inner cylindrical body 70, and the heating distance between the arc-shaped heating plate 46 and the first processed fabric increases.

[0056] In another embodiment of the present invention, preferably, there are eight arc-shaped heating plates 46, which are divided into two groups by the horizontal axial plane of the inner cylindrical body 70: an upper heating group and a lower heating group. Each of the upper and lower heating groups includes four arc-shaped heating plates 46. The four arc-shaped heating plates 46 in the lower heating group are connected to the inner cylindrical body 70 via a connecting rod drive member 74. The two middle arc-shaped heating plates 46 in the upper heating group are connected to the inner cylindrical body 70 via the connecting rod drive member 74, and the other two arc-shaped heating plates 46 are connected via a fixing connector 7. 7 is connected to the annular mounting body 72, so that when the sliding seat 442 moves along the horizontal sliding groove 110 to the first working position, the distance between the four arc-shaped heating plates 46 of the lower heating group and the two movable arc-shaped heating plates 46 of the upper heating group and the center of the inner cylindrical body 70 is at its maximum, while the distance between the two fixed arc-shaped heating plates 46 and the center of the inner cylindrical body 70 remains unchanged (maintained at the minimum distance). This has the following effects: First, the heating gap between the arc-shaped heating plates 46 of the lower heating group and the first processed fabric is minimized, improving the heating effect on the first processed fabric; Second, the annular heating... An annular heating gap 42 is formed between the body 45 and the inner cylindrical body 70. This annular heating gap 42 contains heat. When the four arc-shaped heating plates 46 of the lower heating group and the two movable arc-shaped heating plates 46 of the upper heating group are driven to their maximum distance positions, a heat dissipation gap is formed between them. Thus, the heat inside the annular heating gap 42 dissipates through this gap, improving the heating effect. Thirdly, heat-absorbing elements are also provided on the upper arc-shaped compensation cover 600 and the upper arc-shaped insulation cover 601. The heat-conducting structure 67 provides both heat transfer and heat conduction. When the upper heating element 40 and the lower heating element 41 are driven to the second working position, the heat-conducting structure 67 on the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 corresponds exactly to the heat dissipation gap between the two movable arc-shaped heating plates 46 of the upper heating group, thereby transferring heat to the upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601. The upper arc-shaped compensation cover 600 and the upper arc-shaped heat insulation cover 601 can disperse the heating heat, and the dispersed heat can heat the upper processed fabric located inside them, further improving the heating effect.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
