Description

Technical Field

[0001] The invention relates to the technical field of grey cloth processing, in particular to a grey cloth pressing device. Background Art

[0002] Grey cloth compaction refers to the process of applying pressure to the grey cloth through certain mechanical or physical means to achieve a certain degree of tightness and stability. This step usually occurs in the post-processing stage of grey cloth processing, aiming to improve the quality and applicability of the grey cloth. Through the compaction operation, the gaps inside the grey cloth can be reduced and the contact area between the fibers can be increased, thereby improving the tightness of the grey cloth. The compacted grey cloth has better dimensional stability and shape stability, which helps to reduce deformation and wrinkling in subsequent processing. Proper compaction can improve the feel of the grey cloth, making it softer and smoother. The compacted grey cloth fibers are more closely arranged, which helps to improve the wear resistance and tear resistance of the grey cloth.

[0003] The process of pressing the grey cloth is generally carried out during the rolling process. The grey cloth is stretched and rolled on the shaft, which naturally causes the grey cloth to be in a pressed state. However, in this case, the grey cloth is stretched for a long time in this state, making it difficult for the grey cloth to recover, affecting the quality of the grey cloth.

[0004] The other method is to squeeze the rolled grey fabric during the rolling process so that the grey fabric is not stretched during normal rolling. However, there may still be gaps between the rolled grey fabrics after squeezing them, which will cause looseness in the future and lack the compacting effect. In addition, local wrinkles will be generated during the rolling process of the grey fabric. Therefore, when the grey fabric is rolled, the moving speed of the grey fabric should be the same as the linear speed of the rolled grey fabric, so that the grey fabric is not subject to pulling force and can fit with the rolled grey fabric. The moving grey fabric is squeezed when it is just rolled onto the rotating shaft, so that the grey fabric can be compacted.

[0005] Based on the above proposal, when the grey cloth is rolled up, the movement speed of the grey cloth to be rolled up needs to be the same as the wiring speed of the grey cloth after rolling up, and the grey cloth to be rolled up needs to be squeezed just after rolling up. Summary of the invention

[0006] The object of the present invention is to provide a grey cloth pressing device to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a grey cloth pressing device, comprising a base, on which two symmetrical outer support frames are fixed, inner support rings are fixed on the inner sides of the two outer support frames, and a winding extrusion part is provided between the two outer support frames, and the winding extrusion part is used to apply an extrusion force to the grey cloth when it is rolled up;

[0009] Furthermore, a servo motor is fixed on the outer side of the outer support frame on one side, the rotating shaft is installed between the outer support frames on both sides, and the servo motor is used to drive the rotating shaft to rotate.

[0010] Furthermore, the outer support frames on both sides have a U-shaped frame on the inner side, and the rotating shaft is embedded in the U-shaped frame from top to bottom;

[0012] Both ends of the rotating shaft are provided with bayonet sockets, and the bayonet sockets can cooperate with the polygonal block. A through hole 1 is penetrated in the rotating shaft, and the through hole 1 coincides with the axis of the rotating shaft. When the bayonet socket cooperates with the polygonal block, the axis of the through hole 1 coincides with the axis of the through hole 2. A shaft rod for limiting the rotating shaft is inserted into the through hole 1 and the through hole 2, and the rotating shaft can be taken out upward by taking out the shaft rod.

[0013] Furthermore, the two transmission shafts are rotatably mounted between the outer support frames on both sides, the two outer support frames are located on the sides of the rotating shaft, and gears are fixed to the ends of the two transmission shafts, and the two gears are meshed with each other;

[0014] The two transmission shafts are distributed up and down.

[0015] Furthermore, the outer support frame on the other side is provided with an arc-shaped opening 1 which is arranged through, and the inner support ring on the other side is provided with an arc-shaped opening 2 which is arranged through, the arc-shaped opening 1 and the arc-shaped opening 2 are of the same shape and overlap with each other, the arc-shaped opening 1 is larger than the arc-shaped opening 2, and the axes of the arc-shaped opening 1 and the arc-shaped opening 2 overlap with the axis of the transmission shaft at the lower end;

[0016] The driving shaft is inserted into arc-shaped opening 1 and arc-shaped opening 2. A supporting circular layer is fixed on the driving shaft. The supporting circular layer is embedded in arc-shaped opening 1. The width of arc-shaped opening 1 is the same as the diameter of the supporting circular layer. A transmission belt is transmitted between the transmission shaft and the driving shaft at the lower end. The transmission belt is used to drive the transmission shaft to rotate.

[0017] Furthermore, the outer side of the driving shaft is pressed against the outer wall of the rolled grey cloth, and the diameter of the driving shaft is the same as the diameter of the transmission shaft, so as to control the transmission speed of the grey cloth to be the same as the linear speed of the winding.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. The grey cloth is transmitted and rolled up under the action of the servo motor to prevent the grey cloth from being stretched. Secondly, when the grey cloth is just rolled up, the rolling position is squeezed by the driving shaft, so that the rolled grey cloth is compressed, the gap inside the grey cloth is reduced, and the contact area between the fibers is increased, thereby improving the compactness of the grey cloth. The compressed grey cloth has better dimensional stability and shape stability.

[0022] 2. Under the guidance of the guide shaft, no matter how large the diameter of the grey cloth is after winding, the grey cloth to be wound can pass through the driving shaft and be squeezed by the driving shaft, so that the grey cloth is compressed while avoiding wrinkles.

[0023] 3. The length of the transmission belt is maintained through the arc-shaped opening 1 and the arc-shaped opening 2, and no adjustment is required, which increases a certain stability. As the diameter of the grey cloth after winding increases, the speed of the grey cloth to be wound remains the same as the linear speed of the grey cloth after winding. When the diameter of the grey cloth after winding is different, the stability remains unchanged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 8 The present invention provides a technical solution: a grey cloth pressing device, such as Figure 1 As shown, it includes a base 1, on which two symmetrical outer support frames 2 are fixed, and inner support rings 3 are fixed on the inner sides of the two outer support frames 2, and a winding and squeezing portion 4 is provided between the two outer support frames 2, and the winding and squeezing portion 4 is used to apply squeezing force to the grey cloth when winding;

[0036] like Figure 2As shown, the diameter gradually increases during the winding process, and the position where the grey cloth is just wound is limited by the driving shaft 44. The winding and extruding part 4 includes a rotating shaft 41, a transmission shaft 42, a guide shaft 43 and a driving shaft 44. The rotating shaft 41 is used for winding the grey cloth, and two transmission shafts 42 are provided. The two transmission shafts 42 are used to clamp the grey cloth so that the movement speed of the grey cloth is the same as the wiring speed of the grey cloth after winding. The guide shaft 43 is used to change the transmission direction of the grey cloth, and the driving shaft 44 is used to squeeze the grey cloth when winding. When the grey cloth is wound, it passes through the two transmission shafts 42, then changes direction through the guide shaft 43, and then is squeezed by the driving shaft 44 and then wound.

[0037] like Figure 6 As shown, the rotating shaft 41 needs to be controlled to rotate by the servo motor 5. The servo motor 5 is fixed to the outside of the outer support frame 2 on one side. The rotating shaft 41 is installed between the outer support frames 2 on both sides. The servo motor 5 is used to drive the rotating shaft 41 to rotate.

[0038] like Figure 6 , Figure 7 and Figure 8 As shown, the inner side of the outer support frame 2 on both sides has a U-shaped frame 413, and the rotating shaft 41 is embedded in the U-shaped frame 413 from top to bottom. The U-shaped frame 413 is arranged to facilitate the taking and placing of the rotating shaft 41, and the blank cloth after winding can be directly taken out upwards;

[0039] The outer support frames 2 on both sides are also rotatably mounted with circular ends 414, which are embedded in the outer support frames 2, and a polygonal block 415 is fixed on the inner side of the circular end 414, and a second through hole 416 is horizontally penetrated on the polygonal block 415;

[0040] Both ends of the rotating shaft 41 are provided with a bayonet 411, which can cooperate with the polygonal block 415. A through hole 1 412 is penetrated by the rotating shaft 41, and the through hole 1 412 coincides with the axis of the rotating shaft 41. When the bayonet 411 cooperates with the polygonal block 415, the axis of the through hole 1 412 coincides with the axis of the through hole 2 416. A shaft rod 417 for limiting the rotating shaft 41 is inserted into the through hole 1 412 and the through hole 2 416. The rotating shaft 41 can be taken out upward by taking out the shaft rod 417. The bayonet 411 can cooperate with the polygonal block 415, so that the servo motor 5 can drive the rotating shaft 41 to rotate, which is convenient for installation and disassembly. Secondly, the shaft rod 417 is used to limit the rotating shaft 41 to prevent the rotating shaft 41 from separating from the polygonal block 415 during the winding process.

[0041] like Figure 3 and Figure 4 As shown, two transmission shafts 42 are rotatably installed between the outer support frames 2 on both sides, and the two outer support frames 2 are both located on the side of the rotating shaft 41. Gears 421 are fixed to the ends of the two transmission shafts 42. The two gears 421 are meshed with each other, so that the two transmission shafts 42 clamp the grey cloth and transmit the grey cloth;

[0042] The two transmission shafts 42 are arranged vertically.

[0043] The outer support frame 2 on the other side is provided with an arc-shaped opening 1 45 extending therethrough, and the inner support ring 3 on the other side is provided with an arc-shaped opening 2 46 extending therethrough. The arc-shaped opening 1 45 and the arc-shaped opening 2 46 are of the same shape and overlap with each other. The arc-shaped opening 1 45 is larger than the arc-shaped opening 2 46. The axes of the arc-shaped opening 1 45 and the arc-shaped opening 2 46 overlap with the axis of the transmission shaft 42 at the lower end.

[0044] The driving shaft 44 is inserted into the arc-shaped opening 1 45 and the arc-shaped opening 2 46. A supporting circular layer 47 is fixed on the driving shaft 44. The supporting circular layer 47 is embedded in the arc-shaped opening 1 45. The width of the arc-shaped opening 1 45 is the same as the diameter of the supporting circular layer 47. A transmission belt 48 is transmitted between the transmission shaft 42 at the lower end and the driving shaft 44. The transmission belt 48 is used to drive the transmission shaft 42 to rotate.

[0045] The arc-shaped opening 1 45 and the arc-shaped opening 2 46 are used to limit the drive shaft 44, and the drive shaft 44 can move along the arc-shaped opening 1 45 and the arc-shaped opening 2 46 to limit the drive shaft 44. Even if the drive shaft 44 is moving, it can still maintain the same distance with the transmission shaft 42 at the lower end, which is convenient for installing the transmission belt 48 and is not easy to slip.

[0046] The outer side of the driving shaft 44 is squeezed against the outer wall of the rolled grey cloth, and the diameter of the driving shaft 44 is the same as the diameter of the transmission shaft 42, which is used to control the transmission speed of the grey cloth to be the same as the linear speed of winding. When the rotating shaft 41 rotates, the rolled grey cloth on the outer side also rotates, and the driving shaft 44 is squeezed against the rolled grey cloth and also rotates. The transmission shaft 42 is driven to rotate through the transmission belt 48 to realize the winding of the grey cloth. At the same time, the transmission speed of the grey cloth in transmission before winding is the same as the linear speed of winding.

[0047] An outer supporting shaft 49 is rotatably installed on the outer side of the outer supporting frame 2 on the other side, and an elastic belt 401 is transmitted between the supporting outer shaft 49 and the driving shaft 44. The elastic belt 401 is used to make the driving shaft 44 and the rolled grey cloth have an extrusion effect. The elastic belt 401 provides a supporting effect, so that the driving shaft 44 and the rolled grey cloth have an extrusion effect, and the driving shaft 44 rotates while maintaining the extrusion force.

[0048] like Figure 5 As shown, the guide shaft 43 is rotatably installed between the outer support frames 2 on both sides, and the guide shaft 43 is located between the two transmission shafts 42 and the driving shaft 44, and is used to make the grey cloth that has just been rolled up always pass through the driving shaft 44, change the transmission direction of the grey cloth, make the grey cloth always pass through the driving shaft 44, and when the diameter of the rolled grey cloth gradually increases, the grey cloth is also kept passing through the driving shaft 44.

[0049] The working principle of the present invention is as follows: Figure 2 As shown, the arrow indicates the movement direction of the grey cloth, and the grey cloth passes through two transmission shafts 42, a guide shaft 43 and a driving shaft 44 in sequence, and then is wound onto the rotating shaft 41, and the grey cloth is wound up;

[0050] In the above process, the rolled grey cloth rotates to drive the driving shaft 44 to rotate. As the diameter of the rolled grey cloth increases, the driving shaft 44 will move outward along the arc-shaped opening 1 45 and the arc-shaped opening 2 46, and will always be squeezed with the rolled grey cloth under the action of the elastic belt 401 to complete the squeezing effect. In addition, the rolled cloth rotates along with the rotating shaft 41, so that the driving shaft 44 rotates along with the rolled cloth. The driving shaft 44 and the transmission shaft 42 at the lower end are transmitted through the transmission belt 48, so that the transmission shaft 42 rotates, and under the action of the gear 421, the clamped grey cloth is transmitted, and the transmission speed is the same as the winding speed, so as to avoid the grey cloth from being stretched and wrinkles.

[0051] Based on the above description, the grey cloth is transmitted and rolled up under the action of the servo motor 5 to prevent the grey cloth from being stretched. Secondly, when the grey cloth is just rolled up, the rolling position is squeezed by the drive shaft 44, so that the rolled grey cloth is compressed, the gap inside the grey cloth is reduced, and the contact area between the fibers is increased, thereby improving the compactness of the grey cloth. The compressed grey cloth has better dimensional stability and shape stability.

[0052] In addition, under the guidance of the guide shaft 43, no matter how large the diameter of the grey cloth after winding is, the grey cloth to be wound can pass through the drive shaft 44 and be squeezed by the drive shaft 44, so that the grey cloth is compressed while avoiding wrinkles.

[0053] The length of the transmission belt 48 is maintained through the arc-shaped opening 45 and the arc-shaped opening 46 without adjustment, thereby increasing a certain stability. As the diameter of the grey cloth after winding increases, the speed of the grey cloth to be wound remains the same as the linear speed of the grey cloth after winding. When the diameter of the grey cloth after winding is different, the stability remains unchanged.
