DETAILED DESCRIPTION
[0021] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Example 1
[0022] A new dyeing machine for polyester tent cloth, such as Figure 1-Figure 3 The cloth-clothing machine of embodiment 1 is as shown in Figure 2, comprises a frame 1, the upper side of the frame 1 is fixedly connected to a box body 2, the box body 2 is provided with a driving device and two box doors 3, the driving device is used to control the opening and closing of the box door 3, the driving device of the box body 2 is an existing device, which will not be described in detail here. The box door 3 and the box body 2 are connected by a connecting rod, and the box body 2 is rotatably connected to two cloth-winding rollers 4 and a plurality of cloth-guide rollers 5. The cloth-guide roller 5 is located below the cloth-winding roller 4, and the cloth-winding roller 4 is provided with a cloth-threading groove 401. The cloth-threading groove 401 in the figure is a four-way groove, and the specific shape can be adjusted as needed. The frame 1 is fixedly connected to two motors 6, and the output shaft of the motor 6 is connected to the corresponding cloth-winding roller 4 through a gear box. The frame 1 is fixedly connected to a control terminal 7, and the driving device and motor 6 of the box body 2 are electrically connected to the control terminal 7. The control terminal 7 is used to control the operation of the driving device and the motor 6, and when the cloth on one cloth-winding roller 4 is transferred to another cloth-winding roller 4, the control terminal 7 controls the two motors 6 to adjust the speed to maintain the tension of the cloth during transfer. The surface of the cloth winding roller 4 is provided with textures for increasing friction, so as to reduce the probability of the cloth slipping.
[0023] After the dye is added, the control terminal 7 controls the driving device to close the two doors 3. After the closing is completed, the control terminal 7 controls the two motors 6 to work. At this time, the output shaft of the motor 6 drives the corresponding cloth winding roller 4 to rotate. At this time, the two cloth winding rollers 4 rotate counterclockwise from the right view, so that the cloth on the front cloth winding roller 4 passes through the lower side of the two guide rollers 5 and is dyed with dye and then wound on the rear cloth winding roller 4. When there is not much cloth left on the front cloth winding roller 4, the control terminal 7 controls the two motors 6 to rotate in the opposite direction to wind the cloth on the rear cloth winding roller 4 back to the front cloth winding roller 4. The above process is repeated many times until it meets the process requirements. Here, the cloth is finally wound on the front cloth winding roller 4 as an example. Then the control terminal 7 controls the motor 6 to stop working and controls the drive device to open the box door 3. Then the rear end of the cloth is removed from the rear cloth winding roller 4. At this time, the control terminal 7 controls the front motor 6 to start again, and the output shaft of the front motor 6 drives the front cloth winding roller 4 to rotate, so that the cloth winding roller 4 releases the cloth on it, thereby completing the dyeing of the cloth. Example 2
[0024] On the basis of Example 1, Figure 3-Figure 5 As shown, the cloth threading groove 401 is slidably connected to two sliding frames 8. The sliding frames 8 are provided with two first sliding grooves 801 distributed in a mirror image. The first sliding grooves 801 are slidably connected to a sliding member 9. The sliding member 9 is slidably connected to a clamping plate 10. The clamping plate 10 is used to clamp the cloth. After the clamping plate 10 clamps the cloth, the position of the sliding frame 8 can be adjusted to flatten the end of the cloth. The sliding frame 8 is rotatably connected to a bidirectional threaded rod 11. The bidirectional threaded rod 11 is threadedly connected to the two corresponding sliding members 9. The bidirectional threaded rod 11 is provided with symmetrically distributed threaded portions. The two sliding members 9 are respectively located in different threaded portions, so that the two sliding members 9 can move toward or away from each other at the same time. Neither the sliding frame 8 nor the clamping plate 10 will exceed the cloth threading groove 401, thereby maintaining the uniformity of the surface diameter of the cloth winding roller 4 and allowing the cloth to be evenly wound around the cloth winding roller 4.
[0025] like Figure 3-Figure 5 As shown, the sliding frame 8 is provided with a second sliding groove 802, the second sliding groove 802 is perpendicular to the first sliding groove 801, the second sliding groove 802 is slidably connected to the adjusting member 12, the adjusting member 12 is slidably connected to the corresponding two clamping plates 10, the sliding frame 8 is rotatably connected to the one-way threaded rod 13, the one-way threaded rod 13 is threadedly connected to the adjusting member 12, the one-way threaded rod 13 rotates to drive the adjusting member 12 to move, so that the adjusting member 12 drives the position of the two clamping plates 10 to change, and then the two clamping plates 10 move the corners of the cloth, so that the tension on both sides of the cloth is equal, so that the wrinkles of the cloth are reduced when it is wound on the cloth roller 4.
[0026] like Figure 4 and Figure 5 As shown, the clamping plate 10 is fixedly connected to an elastic plate 1001, and the elastic plate 1001 is used to protect the cloth and reduce damage to the cloth through elastic clamping.
[0027] like Figure 4 and Figure 5 As shown, the elastic plate 1001 is fixed with a plurality of thorns 1002, which are used to increase the friction on the cloth. The thorns 1002 are also made of elastic material to prevent the cloth from being punctured.
[0028] Before passing the cloth into the cloth threading groove 401, the two sliding racks 8 on the same cloth winding roller 4 are slid so that the distance between the two sliding racks 8 corresponds to the width of the cloth to be dyed. After the cloth passes through the two clamping plates 10 on the same sliding rack 8, the bidirectional threaded rod 11 is rotated. The bidirectional threaded rod 11 moves the two sliding members 9 toward each other through the threaded transmission. The sliding members 9 drive the clamping plates 10 to move, so that the two clamping plates 10 on the same sliding rack 8 clamp the cloth. When the tension on both sides of the cloth is different, the unidirectional threaded rod 13 on the side with low cloth tension is rotated. The unidirectional threaded rod 13 moves through the threaded transmission adjusting member 12, and the adjusting member 12 drives the two clamping plates 10 to move. The two clamping plates 10 move while clamping a corner of the cloth, thereby tightening the cloth, thereby reducing the wrinkles generated when the cloth is wound on the cloth winding roller 4, and thereby improving the uniformity of cloth dyeing. Example 3
[0029] On the basis of Example 2, Figure 2 and Figure 6 As shown, the box body 2 is rotatably connected to two fixed rollers 14, and the box body 2 is slidably connected to four sliding seats 15. The two sliding seats 15 corresponding to the fixed rollers 14 on the same side are rotatably connected to a sliding roller 16. The sliding roller 16 and the corresponding fixed rollers 14 are used to clamp the cloth, thereby squeezing out excess dye on the cloth and making the dye on the cloth more uniform.
[0030] like Figure 6As shown, the box body 2 is slidably connected to four extrusion members 17, which are composed of a rod and a plate. The four extrusion members 17 correspond one-to-one with the four sliding seats 15. The extrusion members 17 and the corresponding box doors 3 squeeze each other. A first spring 18 is provided between the sliding seat 15 and the box body 2, and a second spring 19 is provided between the sliding seat 15 and the extrusion member 17. The first spring 18 and the second spring 19 are initially in a compressed state. When the box door 3 separates from the extrusion member 17, the first spring 18 and the second spring 19 push the sliding seat 15 and the extrusion member 17 to move, respectively. The elastic coefficient of the second spring 19 is greater than the elastic coefficient of the first spring 18, so that the extrusion member 17 can drive the sliding roller 16 to stick to the fixed roller 14.
[0031] After the box door 3 is opened, the extrusion member 17 loses the obstruction of the box door 3. At this time, under the action of the first spring 18 and the second spring 19, the sliding seat 15 and the extrusion member 17 move, and the sliding seat 15 drives the sliding roller 16 to move, so that the sliding roller 16 and the fixed roller 14 are separated. When the cloth is wound on one cloth winding roller 4, the other end of the cloth passes through between the sliding roller 16 and the fixed roller 14, and then passes through the two guide rollers 5 and then passes between the sliding roller 16 and the fixed roller 14 on the other side. When the box door 3 is closed, the box door 3 squeezes the extrusion member 17, and the extrusion member 17 squeezes the second spring 19. The second spring 19 pushes the sliding seat 15 to move, and the sliding seat 15 compresses the first spring 18 and drives the sliding roller 16 to move, so that the sliding roller 16 and the fixed roller 14 clamp the cloth. When the cloth comes out of the dye, the excess dye on the cloth is squeezed out by the sliding roller 16 and the fixed roller 14, so that the dye on the cloth after being wound on the cloth winding roller 4 is more uniform, thereby improving the uniformity of cloth dyeing.
[0032] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will fall within the scope of this invention.
