Description

Technical Field

[0001] The present invention relates to the technical field of grey fabric processing, and specifically to a grey fabric pressing device. Background Art

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

[0003] In the process of pressing the grey fabric, it is generally carried out during the winding process of the grey fabric. The grey fabric being wound is stretched and wound around the rotating shaft, which naturally causes the grey fabric to be in a pressed state. However, in this case, the grey fabric is stretched and in this state for a long time, making it difficult for the grey fabric to recover and affecting the quality of the grey fabric.

[0004] Another method is to squeeze the wound grey fabric during the winding process of the grey fabric so that the normal winding of the grey fabric is not affected by the stretching force. However, when squeezing the wound grey fabric, there may still be voids between the grey fabrics, which may still cause looseness subsequently and does not have the effect of pressing. It will also cause local wrinkles during the winding process of the grey fabric. Therefore, when winding the grey fabric, the moving speed of the grey fabric to be wound should be the same as the linear speed of the wound grey fabric, so that the grey fabric is neither affected by the pulling force nor can it fit with the wound grey fabric. When the moving grey fabric is just wound onto the rotating shaft, it is then subjected to the squeezing force so that the grey fabric can be pressed.

[0005] Based on the above, when winding the grey fabric, it is necessary to make the moving speed of the grey fabric to be wound the same as the linear speed of the wound grey fabric, and at the same time, the grey fabric to be wound needs to be subjected to the squeezing force just after being wound. Summary of the Invention

[0006] The purpose of the present invention is to provide a grey fabric pressing device to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the present invention provides the following technical solution: A grey fabric pressing device includes a base, two symmetric outer support frames are fixed on the base, inner support rings are fixed on the inner sides of the two outer support frames facing each other, and a winding and squeezing part is arranged between the two outer support frames. The winding and squeezing part is used to apply a squeezing force to the grey fabric when winding.

[0008] The coiling and squeezing part includes a rotating shaft, a transmission shaft, a guiding shaft and a driving shaft. The rotating shaft is used for winding the blank fabric. There are two transmission shafts, and the two transmission shafts are used for clamping the blank fabric so that the moving speed of the blank fabric is the same as the linear speed of the blank fabric after winding. The guiding shaft is used for changing the transmission direction of the blank fabric, and the driving shaft is used for squeezing when winding the blank fabric.

[0009] Further, 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 for driving the rotating shaft to rotate.

[0010] Further, on the inner side of the outer support frames on both sides, there are U-shaped frames. The rotating shaft is inserted into the U-shaped frames from top to bottom;

[0011] Circular ends are also rotatably installed on the outer support frames on both sides. The circular ends are inserted into the outer support frames. A polygonal block is fixed on the inner side of the circular ends, and a second through hole is horizontally penetrated through the polygonal block;

[0012] Clamping openings are provided at both ends of the rotating shaft. The clamping openings can cooperate with the polygonal blocks. A first through hole is penetrated through the rotating shaft, and the first through hole coincides with the axis of the rotating shaft. When the clamping openings cooperate with the polygonal blocks, the axes of the first through hole and the second through hole coincide. A shaft rod for limiting the rotating shaft is inserted into the first through hole and the second through hole. Removing the shaft rod can take out the rotating shaft upward.

[0013] Further, the two transmission shafts are rotatably installed between the outer support frames on both sides. The two outer support frames are both located on the side of the rotating shaft. Gears are fixed at the ends of the two transmission shafts, and the two gears mesh with each other;

[0014] The two transmission shafts are arranged vertically.

[0015] Further, an arc-shaped opening one is provided in a penetrating manner on the outer support frame on the other side, and an arc-shaped opening two is provided in a penetrating manner on the inner support ring on this side. The arc-shaped opening one and the arc-shaped opening two have the same shape and coincide. The arc-shaped opening one is larger than the arc-shaped opening two. The axes of the arc-shaped opening one and the arc-shaped opening two coincide with the axis of the lower transmission shaft;

[0016] The driving shaft is inserted into the arc-shaped opening one and the arc-shaped opening two. A support circular layer is fixed on the driving shaft. The support circular layer is inserted into the arc-shaped opening one. The width of the arc-shaped opening one is the same as the diameter of the support circular layer. A transmission belt is arranged between the lower transmission shaft and the driving shaft, and the transmission belt is used for driving 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.

[0018] Furthermore, an outer supporting shaft is rotatably mounted on the outer side of the outer supporting frame on the other side, and an elastic belt is transmitted between the outer supporting shaft and the driving shaft, and the elastic belt is used to make the driving shaft and the rolled grey cloth have an extrusion effect.

[0019] Furthermore, the guide shaft is rotatably installed between the outer support frames on both sides, and the guide shaft is located between the two transmission shafts and the driving shaft, so as to always pass the grey cloth that has just been rolled through the driving shaft.

[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

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a blank pressing device, as Figure 1 shown, including a base 1, two symmetric outer support frames 2 are fixed on the base 1, inner support rings 3 are fixed on the inner sides of the two outer support frames 2 facing each other, and a winding and squeezing part 4 is arranged between the two outer support frames 2. The winding and squeezing part 4 is used to apply a squeezing force when winding the blank;

[0036] As Figure 2As shown, during the winding process, the diameter gradually increases. The position where the base fabric starts to be wound is restricted by the driving shaft 44. The winding extrusion part 4 includes a rotating shaft 41, a transmission shaft 42, a guiding shaft 43, and a driving shaft 44. The rotating shaft 41 is used for winding the base fabric. There are two transmission shafts 42. The two transmission shafts 42 are used to clamp the base fabric so that the moving speed of the base fabric is the same as the linear speed of the wound base fabric. The guiding shaft 43 is used to change the transmission direction of the base fabric. The driving shaft 44 is used to extrude the base fabric during winding. When the base fabric is wound, it passes through the two transmission shafts 42, then the direction is changed by the guiding shaft 43, and then it is extruded by the driving shaft 44 and then wound.

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

[0038] As Figure 6 、 Figure 7 and Figure 8 shown, both sides of the outer support frame 2 have U-shaped frames 413 on the inner side facing inwards. The rotating shaft 41 is inserted into the U-shaped frame 413 from top to bottom. The U-shaped frame 413 is provided to facilitate the taking and placing of the rotating shaft 41. After the winding of the base fabric is completed, it can be directly taken out upwards;

[0039] Circular ends 414 are also rotatably installed on both sides of the outer support frame 2. The circular ends 414 are inserted into the outer support frame 2. A polygonal block 415 is fixed on the inner side of the circular end 414. A second through hole 416 runs horizontally through the polygonal block 415;

[0040] Both ends of the rotating shaft 41 are provided with bayonet slots 411. The bayonet slots 411 can cooperate with the polygonal block 415. A first through hole 412 runs through the rotating shaft 41. The first through hole 412 coincides with the axis of the rotating shaft 41. When the bayonet slots 411 cooperate with the polygonal block 415, the axes of the first through hole 412 and the second through hole 416 coincide. A shaft rod 417 for limiting the rotating shaft 41 is inserted into the first through hole 412 and the second through hole 416. Removing the shaft rod 417 can take out the rotating shaft 41 upwards. The bayonet slots 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 disengaging from the polygonal block 415 during the winding process.

[0041] As Figure 3 and Figure 4 shown, the two transmission shafts 42 are rotatably installed between the two outer support frames 2. Both outer support frames 2 are located on the side of the rotating shaft 41. Gears 421 are fixed at the ends of the two transmission shafts 42. The two gears 421 mesh with each other to clamp the base fabric by the two transmission shafts 42 and transmit the base fabric;

[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 greige cloth. The greige cloth successively passes through two transmission shafts 42, a guiding shaft 43, and a driving shaft 44, and then is wound around a rotating shaft 41 to complete the winding of the greige cloth.

[0050] During the above process, the wound greige cloth rotates to drive the driving shaft 44 to rotate. As the diameter of the wound greige cloth increases, the driving shaft 44 will move outward along the first arc-shaped opening 45 and the second arc-shaped opening 46, and always squeeze the wound greige cloth under the action of the elastic band 401 to complete the squeezing action. In addition, the wound cloth rotates with the rotating shaft 41, causing the driving shaft 44 to rotate with the wound cloth. The driving shaft 44 and the lower transmission shaft 42 are driven by a transmission belt 48 to make the transmission shaft 42 rotate. And under the action of the gear 421, the clamped greige cloth is transmitted, and the transmission speed is the same as the winding speed to avoid the greige cloth being stretched and wrinkled.

[0051] Based on the above description, the greige cloth is transmitted and wound under the action of the servo motor 5 to avoid the greige cloth being stretched. Secondly, when the greige cloth is just wound, the winding position is squeezed by the driving shaft 44, so that the wound greige cloth is pressed tightly, reducing the voids inside the greige cloth and increasing the contact area between the fibers, thereby improving the tightness of the greige cloth. The pressed greige cloth has better dimensional stability and shape stability.

[0052] In addition, under the guiding action of the guiding shaft 43, no matter how large the diameter of the wound greige cloth is, the greige cloth to be wound can pass through the driving shaft 44 and be squeezed by the driving shaft 44, so that the greige cloth is pressed tightly while avoiding wrinkles.

[0053] Through the first arc-shaped opening 45 and the second arc-shaped opening 46, the length of the transmission belt 48 is maintained without adjustment, increasing a certain stability. As the diameter of the wound greige cloth increases, the speed of the greige cloth to be wound is the same as the linear speed of the wound greige cloth. When the diameters of the wound greige cloth are different, the stability remains unchanged.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
