Description

Technical Field

[0001] This application relates to the field of fabric hot pressing technology, and in particular to a hot pressing device. Background Technology

[0002] In the field of textile materials, greige fabric, as a primary product of textiles, directly affects the quality and service life of the final product. With industrialization and technological progress, higher requirements have been placed on the strength, abrasion resistance and other properties of greige fabric.

[0003] A common hot pressing device in related technologies is a machine that combines multiple fabrics. It typically includes a worktable and hot pressing rollers and hot pressing trays set on the worktable. After two fabrics are stacked, they are simultaneously pulled through the hot pressing rollers and hot pressing trays. The hot pressing rollers press against the fabrics and provide pressure and heat to the two fabrics, thus pressing the two fabrics together.

[0004] In the process of developing this application, it was discovered that the technology has at least the following problems: After the fabric is hot-pressed together, the surface temperature is high. If the fabric is directly introduced into other processes at this time, it may affect the processing quality of the fabric. For example, after the fabric is introduced into the spraying equipment, the residual high temperature on the fabric may cause the coating to expand. After the fabric cools down, wrinkles will be left on the coating, affecting the quality of the finished product. Utility Model Content

[0005] In order to quickly reduce the surface temperature of the fabric after hot pressing and minimize the impact of high temperature on the subsequent processing quality of the fabric, this application provides a hot pressing device.

[0006] The hot pressing device provided in this application adopts the following technical solution: A hot pressing device includes a worktable. One end of the worktable is provided with a hot pressing roller and a hot pressing support plate for hot pressing fabric. The other end of the worktable is provided with an output roller for guiding the fabric output. A set of support members are symmetrically arranged on both sides of the middle of the worktable. Two parallel cooling pipes are connected between the set of support members. A heat absorption mechanism is provided inside the cooling pipe for absorbing the heat of the cooling pipe. A heat-conducting sleeve is fitted and rotated around the cooling pipe. The fabric passes through the two heat-conducting sleeves in sequence. One heat-conducting sleeve abuts against one side of the fabric, and the other heat-conducting sleeve abuts against the other side of the fabric.

[0007] By adopting the above technical solution, when the high-temperature fabric after hot pressing passes through two heat-conducting sleeves, the heat on the surface of the fabric will be transferred to the cooling pipe through the heat-conducting sleeves. The heat-absorbing mechanism inside the cooling pipe absorbs the heat, thereby reducing the temperature of the heat-conducting sleeves and achieving the cooling treatment of the fabric. The heat-conducting sleeves can rotate around the cooling pipes, which can reduce the friction between the fabric and the heat-conducting sleeves when the fabric moves, avoid damage to the fabric as much as possible, ensure the flatness and integrity of the fabric, provide the fabric with a suitable temperature for subsequent processes, and improve the fabric processing quality.

[0008] Preferably, the heat absorption mechanism includes a storage tank, a liquid pump, and a cooling pipe. The storage tank contains coolant, the input end of the liquid pump is connected to the storage tank, the cooling pipe is located inside the cooling pipe, and the cooling pipe is connected to the output end of the liquid pump.

[0009] By adopting the above technical solution, the liquid pump introduces the coolant from the storage tank into the cooling pipe. When the coolant flows in the cooling pipe, it absorbs the heat of the cooling pipe, thereby reducing the temperature of the cooling pipe.

[0010] Preferably, the heat absorption mechanism further includes a heat dissipation pipe, which is arranged outside the storage tank along the thread direction. One end of the heat dissipation pipe is connected to the storage tank, and the other end of the heat dissipation pipe is connected to the end of the cooling pipe away from the liquid pump.

[0011] By adopting the above technical solution, the heat dissipation pipe is wound around the outside of the storage tank along the thread direction, which increases the contact area between the heat dissipation pipe and the outside air, and extends the flow path of the coolant in the heat dissipation pipe. This allows the coolant to exchange heat with the outside air more fully when flowing through the heat dissipation pipe, dissipating heat into the air and further improving the cooling effect of the coolant.

[0012] Preferably, the support includes a bracket and a rotating disk. The bracket is fixedly connected to the workbench, and the rotating disk is rotatably connected to the bracket. The axes of the two rotating disks coincide. The end of the cooling pipe is fixed on the rotating disk and passes through the end face of the rotating disk. The workbench is also provided with a rotating assembly for driving the rotating disk to rotate.

[0013] By adopting the above technical solution, the rotating component drives the rotating disk to rotate, thereby driving the cooling tube to rotate, so as to adjust the relative position of the two cooling tubes in the circumferential direction, and thus change the wrap angle and contact area between the heat-conducting sleeve and the fabric. Different thicknesses and materials of fabrics require different degrees of cooling after hot pressing. By rotating the rotating disk, the position and angle of the heat-conducting sleeve can be adjusted to adapt to the cooling requirements of different fabrics and improve the versatility of the hot pressing device.

[0014] Preferably, the rotating assembly includes a worm gear ring, a worm, and a mounting bracket. The mounting bracket is fixedly connected to the support, the worm is rotatably connected to the mounting bracket, the worm gear ring is sleeved and fixed on the rotating disk, and the worm gear ring and the worm mesh with each other.

[0015] By adopting the above technical solution, when the worm is rotated, the worm meshes with the worm wheel ring, driving the worm wheel ring to rotate, thereby causing the rotating disk fixed on the worm wheel ring to rotate. When the worm is stationary, it self-locks the worm wheel ring and the rotating disk, ensuring the stability of the rotating disk and cooling tube during use.

[0016] Preferably, a scale ring is fixedly mounted on the bracket, the scale ring coincides with the axis of the rotating disk, the scale ring has scale lines in the circumferential direction, and a pointer is fixedly mounted on the rotating disk, the pointer pointing to the scale lines.

[0017] By adopting the above technical solution, the scale ring and pointer provide operators with intuitive angle indication. When the rotating disk rotates, the pointer moves on the scale ring, and the operator can accurately read the rotation angle of the rotating disk according to the scale line, thereby determining the coverage area of ​​the fabric on the heat-conducting sleeve.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up support components, cooling pipes, heat absorption mechanisms, and heat-conducting sleeves, heat is conducted through double-sided contact between the heat-conducting sleeves and the high-temperature fabric. Combined with the heat absorption mechanism inside the cooling pipes, heat is quickly removed, achieving efficient cooling of the fabric and rapidly reducing the surface temperature of the fabric after hot pressing, thus minimizing the impact of high temperatures on the subsequent processing quality of the fabric. 2. By setting up a storage tank, liquid pump, cooling pipe, and heat dissipation pipe, the liquid pump drives the coolant to absorb heat from the cooling pipe inside the cooling pipe. When passing through the spiral heat dissipation pipe outside the storage tank, the heat exchange is enhanced by increasing the air contact area and extending the flow path, so that the coolant can be circulated after efficient heat dissipation, ensuring the continuity and reliability of the fabric cooling effect. 3. By setting up a bracket, rotating disk, worm gear ring, worm, mounting bracket, scale ring, and pointer, the angle of the rotating disk can be adjusted. With the visual indication of the scale ring and pointer, the operator can accurately adjust the wrap angle and contact area between the heat-conducting sleeve and the fabric to adapt to the differentiated cooling needs of fabrics of different thicknesses and materials.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a hot pressing device. (Refer to...) Figure 1 The system includes a worktable 1, with a hot press roller 11 and a hot press support plate 12 at one end. Specifically, the hot press support plate 12 is horizontally and fixedly installed on the upper surface of one end of the worktable 1. A first connecting frame is also fixedly installed on the worktable 1, and a cylinder is fixedly installed on the top of the first connecting frame. The output end of the cylinder faces downward and is fixedly attached to an assembly frame. The hot press roller 11 is rotatably connected to the assembly frame, and a hot press area is formed between the hot press roller 11 and the hot press support plate 12 for hot pressing and bonding the fabric.

[0025] Reference Figure 1 The other end of the workbench 1 is provided with an output roller 13. Specifically, the other end of the workbench 1 is fixedly provided with a second connecting frame. A set of output rollers 13 is rotatably arranged on the second connecting frame. A set of output rollers 13 together guides the output of the hot-pressed fabric.

[0026] Reference Figure 1 A set of support members 2 is symmetrically arranged on both sides of the middle of the workbench 1. Each set of support members 2 includes a bracket 21 and a rotating disk 22. The bracket 21 is fixedly connected to the workbench 1, and the rotating disk 22 passes through both sides of the bracket 21 and is rotatably connected to the bracket 21. The axes of the two rotating disks 22 coincide.

[0027] Reference Figure 1Two parallel cooling pipes 221 are connected together between a set of support components 2. Specifically, the ends of the cooling pipes 221 are fixed to the rotating disk 22 and pass through the end face of the rotating disk 22. The two cooling pipes 221 are centrally symmetrical with respect to the axis of the rotating disk 22. A rotating assembly 4 for driving the rotating disk 22 is also provided on the worktable 1. A freely rotatable heat-conducting sleeve 222 is provided over the cooling pipes 221. Both the heat-conducting sleeve 222 and the cooling pipes 221 are made of a high thermal conductivity metal material, such as copper or aluminum. The fabric, after being hot-pressed by the hot-pressing roller 11 and the hot-pressing plate 12, passes through the two heat-conducting sleeves 222 in sequence, forming an S-shaped bend. A heat-absorbing mechanism 3 is provided inside the cooling pipes 221 to absorb the heat from the cooling pipes 221. One heat-conducting sleeve 222 abuts against one side of the fabric, and the other heat-conducting sleeve 222 abuts against the other surface of the fabric, so that the heat-conducting sleeves 222 provide double-sided contact cooling for the fabric.

[0028] Reference Figure 1 and Figure 2 The heat absorption mechanism 3 includes a storage tank 31, a liquid pump 32, a cooling pipe 33, and a heat dissipation pipe 34. The storage tank 31 is fixed below the workbench 1 and contains coolant. The input end of the liquid pump 32 is connected to the storage tank 31 via a pipe, and the output end is connected to one end of the cooling pipe 33 via a hose. The cooling pipe 33 is laid inside the cooling pipe 221 along the thread direction and contacts the inner wall of the cooling pipe 221. The heat dissipation pipe 34 is fixed outside the storage tank 31 along the thread direction. One end of the heat dissipation pipe 34 is connected to the storage tank 31, and the other end of the heat dissipation pipe 34 is connected to the end of the cooling pipe 33 away from the liquid pump 32 via a hose, forming a coolant circulation loop.

[0029] Reference Figure 1 and Figure 2 When the liquid pump 32 is working, it introduces the coolant from the storage tank 31 into the cooling pipe 33. As the coolant flows through the cooling pipe 33, it absorbs heat from the cooling pipe 221. The heated coolant is then discharged back to the storage tank 31 through the heat dissipation pipe 34. The heat dissipation pipe 34 allows the coolant to exchange heat with the outside air through the pipe wall during its flow, dissipating the heat. The cooled liquid then flows back to the storage tank 31, achieving circulating heat dissipation.

[0030] Reference Figure 1The rotating assembly 4 includes a worm gear ring 41, a worm 42, and a mounting bracket 43. The mounting bracket 43 is fixed to the inner side of a support 21, and the worm 42 is rotatably connected to the mounting bracket 43. A knob is fixedly installed at the end of the worm 42. The worm gear ring 41 is sleeved and welded to the outer circumference of a rotating disk 22, and the worm gear ring 41 and the worm 42 mesh with each other. When the worm 42 is rotated, the worm gear ring 41 drives the rotating disk 22 to rotate around its axis. The two cooling pipes 221 rotate around the axis of the rotating disk 22 and change position, which intensifies or weakens the S-shaped curvature of the fabric, and the contact area between the heat-conducting sleeve 222 and the fabric changes accordingly. Different thicknesses and materials of fabric require different degrees of cooling after hot pressing. By rotating the rotating disk 22, the contact area between the heat-conducting sleeve 222 and the fabric can be adjusted to meet the cooling requirements of different fabrics.

[0031] Reference Figure 1 and Figure 3 A scale ring 44 is fixed on the bracket 21. The scale ring 44 is coaxial with the rotating disk 22, and angle scale lines are marked on the circumference of the scale ring 44. A pointer 45 is fixed on the rotating disk 22. The pointer 45 rotates with the rotating disk 22 and points to the scale line of the scale ring 44, which makes it easy for the operator to control the rotation angle of the rotating disk 22.

[0032] The implementation principle of the hot pressing device in this embodiment is as follows: After hot pressing, the high-temperature fabric is output from between the hot pressing roller 11 and the hot pressing plate 12. When passing through the middle of the worktable 1, it passes around two heat-conducting sleeves 222 in sequence. The heat on the surface of the fabric is conducted to the cooling pipe 221 through the heat-conducting sleeves 222, and then absorbed by the coolant flowing in the cooling pipe 33 inside the cooling pipe 221. The liquid pump 32 drives the coolant to circulate. The coolant that has absorbed heat is cooled down by the heat dissipation pipe 34 outside the storage tank 31 and flows back to the storage tank 31 for reuse.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
