[0004] The above device cannot effectively fix the fabric when heat-setting the fabric, which will cause the fabric to shrink during the heat-setting process and easily lead to deformation of the fabric. Summary of the invention

[0005] The present application provides a cloth heat setting machine, which fixes and conveys the cloth by inserting multiple pins on two chains through both ends of the cloth, so that the cloth is not easily contracted and deformed during heat setting.

[0006] The present application provides a fabric heat setting machine that adopts the following technical solution: A cloth heat setting machine comprises a machine body, wherein the machine body is provided with a heating chamber, and two ends of the machine body are provided with a cloth inlet and a cloth outlet connected to the heating chamber, and the machine body is also provided with a winding mechanism for winding up the cloth after heat setting, and the cloth inlet and the cloth outlet are both rotatably connected with a rotating shaft, and the machine body is also provided with two driving parts for respectively driving the two rotating shafts to rotate, and gears are sleeved on both ends of the two rotating shafts, and chains are sleeved on the two gears on the same side, and a plurality of pins for inserting cloth are provided on the chain.

[0007] By adopting the above technical solution, the machine is started so that the two driving parts drive the two shafts to rotate, thereby driving the two chains to rotate, and then the cloth is fed into the cloth inlet through the external cloth feeding device. After the cloth enters the cloth inlet, the multiple pins on the two chains will respectively penetrate the cloth bodies on both sides of the cloth during the rotation of the chains, thereby fixing the cloth. After the multiple pins on the two chains penetrate the cloth, the two chains will also bring the cloth into the heating chamber during the transmission and rotation process so that the cloth is heat-set. When the cloth is heat-set, the multiple pins on the two chains will always pull the sides of the cloth, thereby preventing the cloth from shrinking and deforming during heat-setting.

[0008] Preferably, the driving part includes a driving motor arranged on the machine body, a first rotating wheel arranged on the output shaft of the driving motor, an annular groove 1 opened on the first rotating wheel, a second rotating wheel arranged on the rotating shaft, annular groove 2 opened on the second rotating wheel, and a connecting belt mounted on the annular groove 1 and the annular groove 2.

[0009] By adopting the above technical solution, after the machine is started, the two driving motors rotate to drive the two first wheels to rotate, and the rotation of the two first wheels will drive the two second wheels to rotate through the connecting belts, and the rotation of the two second wheels will drive the two shafts to rotate, thereby rotating the four gears and allowing the two chains to rotate continuously.

[0010] Preferably, a first sliding groove is provided on the two rotating shafts, a slider is provided on the four gears, the four sliders are respectively slidably connected in the corresponding first sliding grooves, two of the first sliding grooves are rotatably connected with screw rods, the two screw rods are provided with two threaded sections with opposite thread directions, the two sliders in the same sliding groove are respectively threadedly connected to the two threaded sections of the screw rod in the same sliding groove, and the machine body is also provided with two driving mechanisms for respectively driving the two screw rods to rotate.

[0011] By adopting the above technical solution, different fabrics have different widths, so before the fabric is heat-set, the distance between the two chains needs to be adjusted so that the pins on the two chains can penetrate the two sides of the fabric when the fabric is heat-set to fix and prevent the fabric from shrinking. When the positions of the two chains need to be adjusted, two driving mechanisms are first used to rotate the two screws. The rotation of the two screws will drive the two sliders located in the same first slide groove to slide closer to each other or slide away from each other, so that the gears on the two different shafts on the same side move synchronously. When the two gears on the same side move synchronously, the movement of the chains mounted on the two gears on the same side will change their positions, and finally the effect of adjusting the positions of the two chains is achieved, thereby finally adjusting the distance between the two chains.

[0012] Preferably, one end of the screw rod extends out of a corresponding rotating shaft, and the driving mechanism includes a third rotating wheel arranged on the end of the screw rod extending out of the corresponding rotating shaft, and a third annular groove opened on the outer wall of the third rotating wheel for accommodating a connecting belt, the second annular groove is connected to the adjacent third annular groove, and the width of the first annular groove is greater than the width of the second annular groove plus the width of the third annular groove.

[0013] By adopting the above technical solution, when the distance between the two chains needs to be adjusted, the two connecting belts are first moved to the ring groove three, and the positions of the two connecting belts in the two ring grooves one are also adjusted. Then, the forward and reverse directions of the two driving motors are adjusted as needed, and then the two driving motors are started. After the two driving motors are started, the two first rotating wheels will rotate, and when the two first rotating wheels rotate, the two third rotating wheels will rotate through the two connecting belts, and when the two third rotating wheels rotate, the two lead screws will rotate, and finally the purpose of adjusting the distance between the two chains is achieved.

[0016] Preferably, two pressing wheels are rotatably connected to both sides of the cloth inlet, and the two pressing wheels are respectively located above the two chains. A channel for transmitting one side edge of the cloth is formed between the two pressing wheels and the two chains, and the pressing wheels are used to press the cloth against the pins during the cloth transmission process.

[0017] By adopting the above technical solution, after the cloth enters the cloth inlet, the two sides of the cloth will enter the two channels, and the two rows of pins will penetrate the two sides of the cloth respectively during the rotation of the two chains.

While allowing thick cloth to enter the channel, the pressing wheel also has a certain pressing force on the cloth, ensuring that the pin can penetrate the cloth.

[0020] Preferably, the two pressure wheels are respectively slidably connected to the two connecting rods, and the two connecting rods are each provided with a second sliding groove. The two pressure wheels are slidably connected with a limiting block, and one end of the limiting block extends into the corresponding second sliding groove. The two pressure wheels are threadedly connected with a pressing bolt, and the pressing bolt is used to press the limiting block against the bottom wall of the second sliding groove.

[0021] By adopting the above technical solution, after the positions of the two chains are adjusted, the two pressing bolts are tightened to release the pressing of the two limiting blocks, and then the two pressure wheels can be slid. The positions of the two pressure wheels on the connecting rod are adjusted so that the two pressure wheels are located directly above the two chains, and then the two pressing bolts are tightened again so that the two pressing bolts press the two limiting blocks on the bottom wall of the second slide slot, thereby achieving the limiting effect on the two pressure wheels.

The diameter of the two third gears 21 is equal to the diameter of the two second gears 21. The two third gears 21 are very close to the two second gears 21. The two second ring grooves are connected to the adjacent ring grooves 3 42 respectively. The width of the ring groove 1 33 is greater than the width of the ring groove 2 35 plus the width of the ring groove 3 42.

[0041] Reference Figure 1 , Figure 4-Figure 6 A limiting portion 9 is detachably connected in the annular groove 1 33 , and the limiting portion 9 includes two arc-shaped blocks 91 . The two arc-shaped blocks 91 are connected to each other at their ends to form an annular retaining ring. The connection between the two arc-shaped blocks 91 at their ends is detachably connected to the annular groove 2 35 through fixing bolts 92 .

[0042] Reference Figure 1 and Figure 7 Two mounting seats 61 are also fixed on the machine body 1, and the two mounting seats 61 are located on both sides of the cloth inlet 12. The two mounting seats 61 are slidably connected with sliding blocks 62 along the Z-axis direction, and a cylinder 64 is fixed on the top of the two mounting seats 61, and the output shafts of the two cylinders 64 are fixedly connected to the two sliding blocks 62 respectively.

[0043] Reference Figure 1 and Figure 7 The two sliding blocks 62 are close to each other and are connected to a connecting rod 63 for rotation every year. The two connecting rods 63 are located above the rotating shaft 2 located at the cloth inlet 12. The rotating shaft 2 of the two connecting rods 63 is parallel to the X-axis. A pressing wheel 5 is slidingly connected to the two connecting rods 63 along the X-axis direction. The axes of the two pressing wheels 5 are parallel to the X-axis. Four rows of pressing rods are fixed on the surfaces of the two pressing wheels 5. The four rows of pressing rods on each pressing wheel 5 and the two rows of pins 23 on each chain 22 are staggered with each other.

[0044] Reference Figure 1 , Figure 7 , Figure 8 , the two connecting rods 63 are provided with second slide grooves 71, the two pressing wheels 5 are slidably connected with limit blocks 72, one end of the limit blocks 72 extends into the corresponding second slide grooves 71, and the two pressing wheels 5 are threadedly connected with pressing bolts 73. The pressing bolts 73 are used to press the limit blocks 72 against the bottom wall of the second slide grooves 71.

[0045] Reference Figure 1-Figure 8 The specific steps of using the heat setting machine in this application are as follows: Initially, the two connecting belts 36 are located in the two annular grooves 2 35 and the two annular grooves 1 33. However, because different fabrics 8 have different widths, the distance between the two chains 22 needs to be adjusted before the fabrics 8 are heat-set, so that the pins 23 on the two chains 22 can penetrate the two sides of the fabric 8 during heat-setting to fix the fabric 8 and prevent shrinkage.

[0046] When the distance between the two chains 22 needs to be adjusted, first remove the two arc-shaped blocks 91 on the two rotating shafts 2, then move the two connecting belts 36 to the ring grooves 3 42, and also adjust the positions of the two connecting belts 36 in the two ring grooves 1 33. Then reinstall the two arc-shaped blocks 91 on the two rotating shafts 2. Then adjust the rotation direction of the two driving motors 31 according to the existing distance between the two chains 22 and the width of the cloth 8, so as to achieve the purpose of controlling the two chains 22 to move closer to each other or move away from each other.

[0047] Then, the two driving motors 31 are started. After the two driving motors 31 are started, the two driving motors 31 will drive the two first rotating wheels 32 to rotate. When the two first rotating wheels 32 rotate, the two third rotating wheels 41 will rotate through the two connecting belts 36. When the two third rotating wheels 41 rotate, the two screw rods 26 will rotate. When the two screw rods 26 rotate, the two sliders 25 located in the same first sliding groove 24 will slide closer to each other or slide away from each other, and the gears 21 on the two different rotating shafts 2 on the same side will move synchronously. When the two gears 21 on the same side move synchronously, the chains 22 mounted on the two gears 21 on the same side will move to change their positions, and finally the position of the two chains 22 will be adjusted, and finally the distance between the two chains 22 will be adjusted. So that the pins 23 on the two chains 22 can penetrate the two sides of the cloth 8 when the cloth 8 is heat-set, and play a fixing and shrinkage-proof effect on the cloth 8.

[0048] After the positions of the two chains 22 are adjusted, the two pressing bolts 73 are tightened to release the pressing of the two limiting blocks 72, and the two pressing wheels 5 can be slid. The positions of the two pressing wheels 5 on the connecting rod 63 are adjusted so that the two pressing wheels 5 are located directly above the two chains 22, and then the two pressing bolts 73 are tightened again so that the two pressing bolts 73 press the two limiting blocks 72 on the bottom wall of the second slide groove 71, thereby limiting the two pressing wheels 5.

[0049] Then, the two sliders 25 are controlled to slide by the extension and retraction of the piston rods of the two cylinders 64, thereby adjusting the height of the two sliding blocks 62, so as to control the distance between the two pressing wheels 5 and the two chains 22, thereby achieving the effect of adjusting the height of the channel, allowing thick cloth 8 to enter the channel while also allowing the pressing wheel 5 to have a certain pressing force on the cloth 8, ensuring that the pin 23 can penetrate the cloth 8.

[0050] After the positions of the two chains 22 and the two pressure wheels 5 are adjusted, the four arc-shaped blocks 91 in the two ring grooves 35 are removed again, and then the positions of the two connecting belts are adjusted so that the two belts are moved back into the two ring grooves 35, and then the four arc-shaped blocks 91 are reinstalled to limit the two connecting belts 36.

[0051] Then start the machine so that the two driving motors 31 are started. The two driving motors 31 rotate and drive the two first rotating wheels 32 to rotate. The rotation of the two first rotating wheels 32 will drive the two second rotating wheels 34 to rotate through the connecting belt 36. When the two second rotating wheels 34 rotate, they will drive the two rotating shafts 2 to rotate, thereby rotating the four gears 21 and allowing the two chains 22 to rotate continuously.

[0052] Then the cloth 8 is fed into the cloth inlet 12 through the external cloth feeding device. After the cloth 8 enters the cloth inlet 12, the two sides of the cloth 8 will enter the two channels respectively. At this time, the two rows of pins 23 located on the two chains 22 will penetrate the cloth bodies on both sides of the cloth 8 respectively during the rotation of the chains 22, thereby fixing the cloth 8. At the same time, the two pressing wheels 5 will press down the cloth 8 during the process of the two rows of pins 23 penetrating the cloth 8, so that the cloth 8 generates a downward force, making it easier for the pins 23 to penetrate the cloth 8.

[0053] After the multiple pins 23 on the two chains 22 penetrate the fabric 8, the two chains 22 will also bring the fabric 8 into the heating chamber during the transmission and rotation process so that the fabric 8 is heat-set. When the fabric 8 is heat-set, the multiple pins 23 on the two chains 22 will always pull the two sides of the fabric 8, thereby preventing the fabric 8 from shrinking and deforming during heat-setting. The fabric 8 after heat-setting will be rolled up by the winding mechanism 14. When the winding mechanism 14 rolls up the fabric 8, the fabric 8 will naturally rise and tilt, so that the fabric 8 is easier to separate from the multiple pins 23, which is convenient for the winding of the fabric 8. A row of plug holes will be left on both sides where the multiple fabrics 8 are inserted. The part of the fabric 8 with the plug holes cannot be used and will be cut by a cutting device later.

[0054] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
