Description

Technical Field

[0001] The invention relates to the technical field of cloth collecting and unfolding machines, in particular to a cloth collecting and unfolding machine for clothing. Background Art

[0002] In the process of garment production, it is often necessary to unfold or roll up the fabric flatly. Manual operation has the problems of low efficiency and poor unfolding and gathering effect, which cannot meet the expected requirements. Therefore, the fabric unfolding and gathering machine plays an important role, realizes the function of automatic unfolding and gathering of fabric, and improves work efficiency. Usually, before rolling up the fabric, it is necessary to adjust the position of the limit baffle according to the size of the fabric to ensure that the baffle effectively limits the position of the fabric.

[0003] However, in traditional technologies, most of them directly use studs to control the baffles on both sides to expand or retract synchronously. Although this method solves the problem of position adjustment to a certain extent, once the size of the fabric changes greatly, the stud control method requires too many turns and the adjustment speed is slow, which makes the process of expanding and contracting fabrics of different sizes longer and more inefficient.

[0004] Furthermore, if only a simplified relative position adjustment structure is used, the user is required to adjust the positions at the baffles on both sides respectively. This further increases the process of gathering and unfolding the intervals of fabrics of different sizes, and it is also easy for the relative positions of the baffles on both sides to be inconsistent and asymmetrical, resulting in the problem of not being able to effectively meet the fabric limiting requirements during the gathering and unfolding process.

[0005] After the material roller completes the winding and unwinding process, it is usually necessary to replace the material roller to achieve a continuous winding and unwinding process. However, traditional technologies mostly use a process of replacing the material roller by adjusting the position of the material roller and then detaching the material roller laterally from the outer wall of the main roller. However, in this process, frequently removing the material roller from the outer wall of the main roller is likely to cause safety hazards, and the replacement process has a long stroke, and many connecting structures need to be released, which is inefficient. Summary of the invention

[0006] The purpose of the present invention is to solve the problems that when the size of the fabric changes greatly, the control method using the double-headed stud requires too many rotations and the adjustment speed is slow, which makes the process of gathering and unfolding fabrics of different sizes longer and more efficient; the simplified adjustment structure easily causes the gathering and unfolding process to fail to meet the effective fabric limiting requirements; and the traditional technology frequently removes the material roller from the outer wall of the main roller, which is prone to safety hazards, and the replacement process has a long stroke, and many connecting structures need to be released, which is inefficient.

[0011] Preferably, the center of the outer wall of the main shaft is rotatably connected to the driving bracket through a bearing, and the lower part of the driving bracket is fixedly connected to the workbench.

[0012] Preferably, a material roller bracket is fixedly connected to both the front and rear sides of the upper left portion of the workbench, and support rollers are rotatably connected to both the left and right sides of the upper inner wall of the material roller bracket.

[0015] Preferably, side plates are fixedly connected to both the front and rear sides of the upper end of the transverse plate, and a central roller is rotatably connected to the center of the inner wall of the side plate.

[0016] Preferably, connecting rods are provided on the outer sides of the outer walls of the side plates, and the inner walls on both sides of the connecting rods are rotatably connected to the pressure rollers and the side plates respectively through pins.

[0019] Preferably, auxiliary rollers are rotatably connected to the upper left corner, center and right side of the inner wall of the auxiliary roller bracket, and the lengths of the plurality of auxiliary rollers are consistent.

[0020] The invention provides a clothing fabric collecting and unfolding machine, which has the following beneficial effects:

[0021] By adjusting the coordination among the motor, the baffle, the sleeve and the threaded hole, when the position of the baffle needs to be adjusted over a large range, the user only needs to loosen the screw to move the baffle on the outer wall of the sleeve until the baffle is aligned with the threaded hole closest to its adjustment position and stops, then tighten the screw and start the adjustment motor. Since the large-size range adjustment requirement has been adjusted to a smaller position adjustment requirement, the control baffle that can be quickly prepared when adjusting the motor control is adjusted to the corresponding position, effectively avoiding the problem that when the cloth size changes greatly, the double-headed stud control method requires too many turns and the adjustment speed is slow, thereby making the process of the collection and expansion interval of cloths of different sizes longer and more inefficient.

[0022] Through the cooperation between the baffle plate, the crossbar rack and the linkage gear, after the user loosens the screws on both sides, the user only needs to adjust the position of the baffle plate on one side, and the baffle plate can drive the corresponding crossbar rack to move laterally. At the same time, the crossbar rack can drive the crossbar rack on the other side to move through the cooperation of the linkage gear. The crossbar racks on both sides are just opposite, so that the position adjustment of the baffle plates on both sides can be achieved synchronously inward or outward, and the position adjustment of the baffle plates on both sides can be achieved by adjusting only one side, which effectively avoids the problem that the simplified adjustment structure easily causes the inability to meet the effective cloth limiting requirements during the winding and unfolding process;

[0023] Through the coordination among the groove wheel, material roller, support roller, bolts and main shaft, the groove wheel and material roller structure are formed into an integrated structure. When replacement is needed, it is only necessary to release the installation of the bolt at one place, and then lift the material roller upward. At this time, the groove wheel is separated from the support roller and can be taken out. When replacement is needed, it is only necessary to clamp the groove part of the groove wheel on the outer wall of the support roller, and the end of the groove wheel is clamped with the main shaft to complete the installation. Since the protruding part of the main shaft is facing the vertical direction during the taking process, the installation process only requires the material roller to be placed vertically to achieve the connection, and then the replacement can be completed by tightening the bolts. This effectively avoids the safety hazards caused by frequently taking the material roller from the outer wall of the main roller in the traditional technology, and the problems of long stroke, more connection structures that need to be released and poor efficiency during the replacement process.

A linkage component 6 is installed at the upper center of the auxiliary roller bracket 3. A driving component 5 is installed at the upper part and front side of the material roller bracket 4. The outer wall center of the main shaft 503 is rotatably connected to the driving bracket 2 through a bearing. The lower end of the driving bracket 2 The cross plate 10 is fixedly connected to the workbench 1, and the front and rear sides of the upper left part of the workbench 1 are fixedly connected with material roller brackets 4, and the left and right sides of the upper inner wall of the material roller bracket 4 are rotatably connected with support rollers 508, and the front and rear sides of the upper end of the cross plate 10 are fixedly connected with side plates 11, and the center of the inner wall of the side plate 11 is rotatably connected with a center roller 12, and the outer side of the outer wall of the side plate 11 is provided with a connecting rod 13, and the end connection of the connecting rod 13 is installed with a volute spring, which can tighten the pressure roller 14 when the cloth is rolled up and unrolled, and the inner walls on both sides of the connecting rod 13 are rotatably connected with the pressure roller 14 and the side plate 11 respectively through pins, and the upper left corner, center and right side of the inner wall of the auxiliary roller bracket 3 are rotatably connected with auxiliary rollers 15, and the lengths of the multiple auxiliary rollers 15 are consistent.

[0035] Refer to the attached Figure 1-8 : In this embodiment, the driving assembly 5 includes a material roller 501, a groove wheel 502, a main shaft 503, a belt 504, a main pulley 505, a driving motor 506, a slave pulley 507, a support roller 508 and a bolt 509;

[0036] The driving motor 506 is fixedly connected to the front left side of the upper end of the workbench 1. The end of the output shaft of the driving motor 506 is fixedly connected with a main pulley 505. The model of the driving motor 506 can be determined according to the specific usage. The driving motor 506 is a servo motor. The outer wall of the main pulley 505 is rotatably connected with the slave pulley 507 through a belt 504. The rear end center of the slave pulley 507 is fixedly connected with a main shaft 503. The end of the main shaft 503 is a protrusion, and the front side of the rotating shaft of the groove wheel 502 is a notch. The rear end of the main shaft 503 is plugged with the end of the rotating shaft of the front groove wheel 502, and the rear side of the main shaft 503 is fixedly connected with the rotating shaft of the front groove wheel 502 by bolts 509. The inner sides of the rotating shafts of the front and rear groove wheels 502 are fixedly connected with the material roller 501, and both sides of the lower part of the outer wall of the groove wheel 502 are attached with support rollers 508.

[0037] Through the cooperation among the groove wheel 502, the material roller 501, the support roller 508, the bolt 509 and the main shaft 503, the groove wheel 502 and the material roller 501 are formed into an integrated structure. When replacement is needed, it is only necessary to release the installation of the bolt 509, and then lift the material roller 501 upward. At this time, the groove wheel 502 is separated from the support roller 508, so that it can be taken out. When replacement is needed, it is only necessary to clamp the groove part of the groove wheel 502 on the outer wall of the support roller 508, and the end of the groove wheel 502 is clamped with the main shaft 503 to complete the installation. Since the protruding part of the main shaft 503 is facing the vertical direction during the taking process, the material roller 501 only needs to be placed vertically during the installation process to achieve the connection, and then the bolt 509 can be tightened to complete the replacement, which effectively avoids the safety hazards caused by frequently taking the material roller from the outer wall of the main roller in the traditional technology, and the problem of long travel during the replacement process, more connection structures that need to be released and poor efficiency.

[0038] See attached Figure 1-8 : In this embodiment, the limit assembly 7 includes an adjustment motor 701, a sleeve 702, a slide rod 703, a baffle 704, a stud 705, a screw 706 and a threaded hole 707;

[0039] The adjustment motor 701 is fixedly connected to the front upper center of the auxiliary roller bracket 3 on the front side, and a stud 705 is fixedly connected to the end of the output shaft of the adjustment motor 701. The model of the adjustment motor 701 can be determined according to the specific usage. Both sides of the outer wall of the stud 705 are rotatably connected to the auxiliary roller bracket 3 through bearings, and the front and rear sides of the outer wall of the stud 705 are threadedly connected to the sleeve 702, and the outer wall of the sleeve 702 is slidably connected to a baffle 704, and the upper end of the outer wall of the sleeve 702 is equidistantly processed with a plurality of threaded holes 707, the baffle 704 and the sleeve 702 are fixedly connected by threaded holes 707 and screws 706, and the relative position limitation of the baffle 704 and the sleeve 702 is achieved by the cooperation of the threaded holes 707 and the screws 706 at different positions, and the inner walls on both sides of the upper part of the baffle 704 are slidably connected to the sliding rod 703, and the ends of both sides of the sliding rod 703 are fixedly connected to the auxiliary roller bracket 3;

[0040] By adjusting the coordination among the motor 701, the baffle 704, the sleeve 702 and the threaded hole 707, when it is necessary to adjust the position of the baffle 704 over a large range, the user only needs to loosen the screw 706 to move the baffle 704 on the outer wall of the sleeve 702 until the baffle 704 is aligned with the threaded hole 707 closest to its adjustment position and stops, and then tighten the screw 706, and then start the adjustment motor 701. Since the large-size range adjustment requirement has been adjusted to a smaller position adjustment requirement, the control baffle 704 that can be quickly prepared when the adjustment motor 701 is controlled is adjusted to the corresponding position, which effectively avoids the problem that when the size of the fabric changes greatly, the double-headed stud control method requires too many turns and the adjustment speed is slow, which makes the process of the collection and expansion interval of fabrics of different sizes longer and more inefficient.

[0041] Refer to the attached Figure 1-8 : In this embodiment, the linkage assembly 6 includes a crossbeam 601, a crossbar rack 602, a linkage gear 603 and a slide bracket 604;

[0042] The front and rear sides of the lower end of the crossbeam 601 are fixedly connected to the center of the upper end of the auxiliary roller bracket 3. The central inner wall of the crossbeam 601 is rotatably connected to the rotating shaft of the linkage gear 603 through a bearing. The outer walls of the linkage gear 603 are meshed and connected with crossbar racks 602 on both sides. The connection of the linkage gear 603 can realize the synchronous inward or outward adjustment of the crossbar racks 602 on both sides. The end of one side of the crossbar rack 602 is fixedly connected to the baffle 704, and the outer wall of the other side of the crossbar rack 602 is slidably connected to the upper inner wall of the slide bracket 604. The lower end of the slide bracket 604 is fixedly connected to the baffle 704.

[0043] Through the cooperation between the baffle plate 704, the cross bar rack 602 and the linkage gear 603, after the user loosens the screws 706 on both sides, the user only needs to adjust the position of the baffle plate 704 on one side. At this time, the baffle plate 704 can drive the corresponding cross bar rack 602 to move horizontally. At the same time, the cross bar rack 602 can drive the cross bar rack 602 on the other side to move through the cooperation of the linkage gear 603. The cross bar racks 602 on both sides are just opposite. In this way, the baffle plates 704 on both sides can be adjusted inward or outward synchronously, and the position adjustment of the baffle plates on both sides can be achieved by adjusting only one side, which effectively avoids the problem that the simplified adjustment structure easily causes the inability to meet the effective cloth limiting requirements during the winding and unfolding process.

[0044] Working principle:

[0045] When the fabric retracting and unfolding machine for clothing is needed, first, the user can assemble the overall structure as shown in the figure. After the assembly is completed, the user can place the overall structure at the corresponding position. When it is needed, the fabric head to be rolled up is first unfolded, and the fabric head is inserted from the right side of the device, and passes through the auxiliary roller 15, the pressure roller 14 and the center roller 12 in sequence, and finally the end of the fabric head is connected to the clamping part of the material roller 501 for fixing. In this way, all preparations before rolling are completed (when the fabric needs to be unfolded, just follow the steps in reverse). The specific rolling steps are as follows:

[0046] 1. Fabric winding process: After completing the preparation work before winding, the user can control the driving motor 506 so that the output shaft of the driving motor 506 drives the main shaft 503 to rotate through the pulley and the belt 504, and then the main shaft 503 can drive the material roller 501 to rotate through the groove wheel 502 to realize the winding and winding process of the fabric. In this process, the auxiliary roller 15 is used to adjust the direction of fabric input, and the pressure roller 14 is installed with a vortex spring at its connection, so that during the winding process, the pressure roller 14 always applies pressure to the surface of the fabric to keep it in a taut state, and the center roller 12 further adjusts the winding input direction of the fabric. As the material roller 501 rotates continuously, the fabric is wound around the outer wall of the material roller 501 for winding. If the present equipment needs to unwind the fabric roll, it only needs to reverse the operation, that is, connect the fabric head to the external workstation, and then control the driving motor 506 to reverse, so as to realize the process of unwinding the fabric on the outer wall of the material roller 501.

[0047] 2. Cloth limiting process: Before the cloth is rolled up, it is usually necessary to adjust the position of the limiting baffle plate according to the size of the cloth to ensure that the baffle plate effectively limits the cloth position. However, in traditional technologies, most of them directly use studs to control the baffle plates on both sides to expand or retract synchronously. Although this method solves the problem of position adjustment to a certain extent, once the cloth size changes greatly, the stud control method requires too many turns and the adjustment speed is slow, which makes the process of rolling up and down cloths of different sizes longer and more inefficient. Therefore, the baffle plate 704 and the sleeve 702 are designed in this case so that when a large change is required, the baffle plate 704 and the sleeve 702 can be adjusted. When adjusting the position of the baffle 704 within the range, the user only needs to loosen the screw 706 to move the baffle 704 on the outer wall of the sleeve 702 until the baffle 704 is aligned with the threaded hole 707 closest to its adjustment position, and then tighten the screw 706, and then start the adjustment motor 701. Since the large-size range adjustment requirement has been adjusted to a smaller position adjustment requirement, the control baffle 704 can be quickly prepared and adjusted to the corresponding position when the adjustment motor 701 is controlled, which effectively avoids the problem that when the fabric size changes greatly, the double-headed stud control method requires too many turns and the adjustment speed is slow, which makes the process of gathering and expanding fabrics of different sizes longer and more inefficient.

[0048] At the same time, if only a simplified relative position adjustment structure is adopted, the user is required to adjust the position at the baffles on both sides respectively, which further increases the process of collecting and unfolding the intervals of fabrics of different sizes, and it is also easy for the relative positions of the baffles on both sides to be inconsistent and asymmetrical, resulting in the problem that the fabric limiting requirements cannot be effectively met during the collection and unfolding process. Therefore, the present case designs a linkage component 6, so that after the user loosens the screws 706 on both sides, the user only needs to adjust the position of the baffle 704 on one side. At this time, the baffle 704 can drive the corresponding cross bar rack 602 to move laterally. At the same time, the cross bar rack 602 can drive the cross bar rack 602 on the other side to move through the cooperation of the linkage gear 603, and the cross bar racks 602 on both sides are just opposite. In this way, the baffles 704 on both sides can be adjusted inward or outward synchronously, and the position adjustment of the baffles on both sides can be achieved by adjusting only one side, which effectively avoids the problem that the simplified adjustment structure easily causes the fabric limiting requirements to be unable to be effectively met during the collection and unfolding process.

[0049] 3. Material roller replacement process: After the material roller 501 completes the winding and unwinding process, it is usually necessary to replace the material roller 501 to achieve a continuous winding and unwinding process. However, in conventional technology, when replacing the material roller 501, the material roller 501 is mostly replaced by adjusting the position of the material roller and then detaching it from the outer wall of the main roller. However, in this process, frequently removing the material roller from the outer wall of the main roller is prone to safety hazards, and the replacement process has a long stroke, and many connection structures need to be released, which is inefficient. Therefore, the present case designs a drive assembly 5, so that the groove wheel 502 and the material roller 501 structure are formed into an integrated structure. When replacement is required, it is only necessary to release the installation of the bolt 509, and then The material roller 501 is lifted upward, and the groove wheel 502 is now separated from the support roller 508, so it can be taken out. When it needs to be replaced, it is only necessary to clamp the groove part of the groove wheel 502 on the outer wall of the support roller 508, and after the end of the groove wheel 502 is clamped with the main shaft 503, the installation can be completed. Since the protruding part of the main shaft 503 is facing the vertical direction during the removal process, the installation process only requires the material roller 501 to be placed vertically to achieve the connection, and then the bolt 509 can be tightened to complete the replacement, which effectively avoids the safety hazards of frequently removing the material roller from the outer wall of the main roller in the traditional technology, and the problem of long travel during the replacement process, more connection structures that need to be released and poor efficiency.
