Description

Technical Field

[0001] This invention relates to the field of printing and dyeing production equipment technology, and more specifically, to a folding fabric loading device. Background Technology

[0002] The dyeing and printing industry involves numerous production steps, requiring the transfer of fabric between these steps. Fabric transfer is typically done using fabric boxes; that is, after one step is completed, the fabric is folded, packed into a fabric box, and then transported to the next step using trolleys or forklifts. Currently, fabric folding is achieved using a swing head mechanism installed on the equipment. The swing head's left-right swinging motion causes the fabric to reciprocate, thus folding it. However, in practice, it has been found that the folding effect produced by the swing head mechanism is rather arbitrary. Without manual intervention, the folded fabric is not neat. Relying solely on the swing head mechanism for packing fabric results in uneven fabric within the box. This unevenness affects the overall capacity of the fabric box, wasting space and sometimes preventing longer pieces of fabric from being folded into a single box (even if it was anticipated to fit, the unevenness causes insufficient space). Therefore, designing dedicated folding and packing equipment is a key focus of enterprise technological improvement research, leading to this project. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a folding fabric loading device. When using this invention, the fabric passes between two folding rollers, and the folding operation of the fabric is achieved by the reciprocating motion of the folding rollers. In the process of using this invention, since the movement stroke of the folding rollers is fixed, and a hooking mechanism is designed to achieve the positioning of the folding point, the folded fabric is relatively neat. After the application of this invention, the space utilization rate inside the fabric box can be greatly improved.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A folding fabric loading device includes a base, a lateral drive mechanism, and a stacking roller assembly. A vertical frame is fixedly mounted on the base. The lateral drive mechanism is mounted on the side wall of the vertical frame. The stacking roller assembly is driven onto the lateral drive mechanism, which drives the stacking roller assembly to perform a lateral linear motion to form a transverse stacking trajectory. A guide roller assembly is also mounted on the side wall of the vertical frame, positioned directly above the center point of the transverse stacking trajectory. The stacking roller assembly includes a first stacking roller and a second stacking roller, which are horizontally parallel. The fabric is introduced through the guide roller group and then passes through the gap between the first and second fabric folding rollers. As the fabric folding roller group moves laterally, it creates a folding effect on the fabric. A first fabric folding positioning device and a second fabric folding positioning device are respectively installed at both ends of the lateral fabric folding trajectory. The first and second fabric folding positioning devices have the same structure and are symmetrically installed. The first and second fabric folding positioning devices can position the folding points of the fabric.

[0006] Furthermore, the transverse drive mechanism includes a crossbeam, a transmission screw, guide rods, a motor, and a transverse slider. The crossbeam is fixedly installed on the side wall of the upright frame. The transmission screw is rotatably installed inside the crossbeam. Two guide rods are arranged on both sides of the transmission screw and are fixedly installed. The output end of the motor is connected to the transmission screw. The transverse slider passes through the two guide rods and is threadedly connected to the transmission screw. A roller support is fixedly installed on the transverse slider. The first fabric stacking roller and the second fabric stacking roller are installed on the roller support.

[0007] Furthermore, the first and second fabric stacking rollers have the same structure. Both the first and second fabric stacking rollers include a roller shaft, which is vertically and fixedly connected to the roller support. A roller is rotatably mounted on the roller shaft.

[0008] Furthermore, the first fabric stacking positioning device includes a straight beam and two fabric hooking mechanisms. The straight beam is vertically and fixedly connected to the side wall of the upright frame. The two fabric hooking mechanisms are symmetrically installed on the straight beam, and are respectively set at both ends of the fabric width direction.

[0009] Furthermore, the hook mechanism includes a rotating shaft mounting base, a rotating shaft, and a spring seat. The rotating shaft mounting base is fixedly mounted on the straight beam, and the rotating shaft is rotatably mounted on the rotating shaft mounting base. A lever and a hook rod are fixedly connected to the outer wall of the rotating shaft. The lever and the hook rod are arranged at a 90-degree angle. One end of the hook rod is connected to the outer wall of the rotating shaft, and the other end of the hook rod is bent to form a hook head. One spring seat is fixedly connected to the outer wall of the rotating shaft, and the other spring seat is fixedly connected to the rotating shaft mounting base. A spring is installed between the two spring seats.

[0010] Furthermore, two fabric hook drivers are installed on the roller shafts of the first and second fabric stacking rollers. The fabric hook drivers are arranged in a one-to-one correspondence with the fabric hooking mechanism. Each fabric hook driver includes a linkage plate and a striking rod. The linkage plate is fixedly connected to the roller shaft, and the striking rod is fixedly connected to the linkage plate. When the spring is in its normal extended state, the actuating rod blocks the movement trajectory line of the striking rod.

[0011] Furthermore, several wheels with braking function are installed under the base.

[0012] The beneficial effects of this invention are:

[0013] When using this invention, the fabric passes between two folding rollers, and the folding operation of the fabric is achieved by the reciprocating motion of the folding rollers. During the use of this invention, since the movement stroke of the folding rollers is fixed, and a hooking mechanism is designed to position the folding point, the folded fabric is relatively neat. The folding rollers of this invention can operate close to the opening of the fabric box, and can fold the fabric to the limit. After applying this invention, the space utilization rate inside the fabric box can be greatly improved. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-6The illustrated fabric folding device includes a base 1, a transverse drive mechanism 3, and a fabric folding roller assembly 4. A support frame 2 is fixedly mounted on the base 1. The transverse drive mechanism 3 is mounted on the side wall of the support frame 2. The fabric folding roller assembly 4 is driven and mounted on the transverse drive mechanism 3, which drives the fabric folding roller assembly 4 to perform transverse linear motion to form a transverse fabric folding trajectory 5. A guide roller assembly 6 is also mounted on the side wall of the support frame 2, positioned directly above the center point of the transverse fabric folding trajectory 5. The fabric folding roller assembly 4 includes a first fabric folding roller 41 and a second fabric folding roller 42, which are horizontally parallel and have a gap between them. The guide roller assembly 6 includes two guide rollers 61. Fabric is introduced from between the two guide rollers 61 and then passes through the gap between the first fabric folding roller 41 and the second fabric folding roller 42. The guide roller assembly 6 serves as a guide for the fabric introduction. Since the guide roller assembly 6 is located within the transverse fabric folding trajectory 5... The fabric is positioned directly above the center point, so when the fabric stacking roller group 4 moves laterally in a straight line, it can create a uniform left-right folding effect on the fabric. The first fabric stacking positioning device 7 and the second fabric stacking positioning device 8 are respectively installed at both ends of the transverse fabric stacking track 5. The first fabric stacking positioning device 7 and the second fabric stacking positioning device 8 have the same structure and are installed symmetrically. The first fabric stacking positioning device 7 and the second fabric stacking positioning device 8 can position the folding point of the fabric, so that the folded fabric can be neat. This invention is designed according to the size of the existing fabric box of the enterprise. The fabric stacking roller group 4 and the first fabric stacking positioning device 7 and the second fabric stacking positioning device 8 are installed close to the opening of the fabric box. The transverse fabric stacking track 5 matches the opening length of the fabric box. In this way, as the fabric stacking roller group 4 moves back and forth laterally, neat folded fabric can be continuously loaded into the fabric box. The folding length of the fabric matches the fabric box (can be folded to the limit) and is relatively neat, which can well meet the needs of fabric loading operations and greatly improve the space utilization of a single fabric box.

[0023] like Figure 6As shown, the transverse drive mechanism 3 includes a cross frame 31, a transmission screw 32, guide rods 33, a motor 34, and a transverse slider 35. The cross frame 31 is fixedly installed on the side wall of the upright frame 2. The transmission screw 32 is rotatably installed inside the cross frame 31. Two guide rods 33 are arranged on both sides of the transmission screw 32 and are fixedly installed. The output end of the motor 34 is connected to the transmission screw 32. When the motor 34 starts, it can drive the transmission screw 32 to rotate. The transverse slider 35 is mounted on the two guide rods 33 and is threadedly connected to the transmission screw 32. A roller support 36 is fixedly installed on the transverse slider 35. The first fabric stacking roller... The first and second stacking rollers 41 and 42 are mounted on the roller support 36. The guide rod 33 guides the movement of the transverse slider 35. When the motor 34 drives the transmission screw 32 to rotate, the transmission screw 32 can drive the transverse slider 35 to move along the length of the guide rod 33. The roller support 36 is fixedly connected to the transverse slider 35, so the roller support 36 moves with the transverse slider 35. The first and second stacking rollers 41 and 42 are mounted on the roller support 36 and can also move with the roller support 36. In this invention, the motor 34 alternates between forward and reverse rotation to achieve the reciprocating movement effect of the stacking roller group 4. Figure 2 As shown, since the fabric passes through the gap between the first folding roller 41 and the second folding roller 42, when the folding roller group 4 moves to the left, the second folding roller 42 folds the fabric, and when the folding roller group 4 moves to the right, the first folding roller 41 folds the fabric. As the folding roller group 4 moves back and forth, the two folding rollers take turns working, forming an effect of alternating left and right folding of the fabric.

[0024] like Figure 3 As shown, the first fabric folding roller 41 and the second fabric folding roller 42 have the same structure. Both the first fabric folding roller 41 and the second fabric folding roller 42 include a roller shaft 411 and a roller 412. The roller shaft 411 is vertically connected to the roller support 36. Since the fabric folding roller only plays the role of pressing and folding the fabric, the roller shaft 411 can be fixedly installed on the roller support 36. The fabric folding roller relies on the roller 412 to contact the fabric. In order to ensure that the fabric folding roller only plays the role of pressing and folding the fabric, the roller 412 is rotated, so that the lateral movement of the fabric folding roller is very smooth.

[0025] like Figures 1-3 As shown, the first fabric folding positioning device 7 includes a straight beam 72 and two fabric hooking mechanisms 71. The straight beam 72 is vertically and fixedly connected to the side wall of the upright 2. The two fabric hooking mechanisms 71 are symmetrically installed on the straight beam 72. The two fabric hooking mechanisms 71 are respectively set to correspond to the two ends of the fabric width direction. When the two fabric hooking mechanisms 71 are activated, they can hook the two ends of the fabric width direction to achieve the positioning of the fabric folding position. The second fabric folding positioning device 8 has the same structure as the first fabric folding positioning device 7 and is symmetrically arranged. This can form positioning at both folding points of the fabric, ensuring a neat folding effect.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the hook mechanism 71 includes a shaft mounting base 711, a shaft 712, and a spring seat 715. The shaft mounting base 711 is fixedly mounted on the straight beam 72. The shaft 712 is rotatably mounted on the shaft mounting base 711. A lever 713 and a hook rod 714 are fixedly connected to the outer wall of the shaft 712. The lever 713 and the hook rod 714 are arranged at a 90-degree angle. One end of the hook rod 714 is connected to the outer wall of the shaft 712, and the other end of the hook rod 714 is bent to form a hook head 7141. One spring seat 715 is fixedly connected to the outer wall of the shaft 712, and another spring seat 715 is fixedly connected to the shaft mounting base 711. A spring 716 is installed between the two spring seats 715. The position of the lever 713 can form a force-bearing condition. Furthermore, when the actuating lever 713 is subjected to force, it can drive the rotating shaft 712 to rotate, and the position of the hook lever 714 also changes accordingly. Since one end of the spring 716 is connected to the rotating shaft 712, as the rotating shaft 712 rotates, the spring 716 will have a stretching effect. When the actuating lever 713 loses its force, the spring 716's rebound force can drive the rotating shaft 712 to rotate in the opposite direction, forming a reset effect for the actuating lever 713 and the hook lever 714. In this invention, the force on the actuating lever 713 is achieved by the hook actuator 43 installed on the stacking roller group 4. Two hook actuators 43 are installed on the roller shaft 411 of the first stacking roller 41 and the second stacking roller 42. The hook actuators 43 are arranged one-to-one with the hooking mechanism 71, such as... Figure 3 As shown, the two hook actuators 43 on the first fabric stacking roller 41 can correspondingly drive the two hook mechanisms 71 on the left side of the fabric stacking roller group 4 in the direction of movement, and the two hook actuators 43 on the second fabric stacking roller 42 can correspondingly drive the two hook mechanisms 71 on the right side of the fabric stacking roller group 4 in the direction of movement. The hook actuator 43 includes a linkage plate 431 and a striking rod 432. The linkage plate 431 is fixedly connected to the roller shaft 411, so that the hook actuator 43 can move together with the fabric stacking roller. The striking rod 432 is fixedly connected to the linkage plate 431. When the spring 716 is in the normal extended state, the actuating rod 713 blocks the movement trajectory line of the striking rod 432, such as... Figure 2 and Figure 3 As shown, when the stacking roller group 4 moves to the left, the second stacking roller 42 acts as a pressure and stacking roller, and the first stacking roller 41 moves to the position of the hooking mechanism 71 before the second stacking roller 42. The hook driver 43 of the first stacking roller 41 can drive the hooking mechanism 71. Figure 5As shown, when the impact rod 432 of the fabric hook driver 43 strikes the actuating rod 713 of the fabric hook mechanism 71, the actuating rod 713 is actuated by force. At this time, the rotating shaft 712 rotates, the spring 716 is stretched, and the fabric hook rod 714 also rotates outward, with its hook head 7141 moving away from the fabric. After the fabric is folded into place, the folding roller group 4 moves back to the right. At this time, the fabric hook driver 43 of the first folding roller 41 is no longer in contact with the fabric hook mechanism 71. Under the restoring force of the spring 716, the fabric hook rod 714 can quickly return to its original position, and the hook head 7141 can be inserted into the folding bend of the fabric to form a fold. As the stacking roller group 4 moves to the right limit, the two hook drivers 43 on the second stacking roller 42 can also open and close the two hook mechanisms 71 on the right. The opening and closing of the hook mechanism 71 refers to the process of the hook rod 714 completing one outward expansion movement and one reset inward insertion movement. When the hook rod 714 expands outward, the hook head 7141 disengages from the fabric, and the original folding point falls naturally. After the hook rod 714 resets and inserts inward, it can be inserted into the new folding area. This cycle repeats to ensure the uniformity of the folding width. The fabric that is folded and put into the fabric box is also relatively neat.

[0027] like Figure 1 As shown, several traveling wheels 11 with braking function are installed under the base 1, which allows the entire folding fabric loading device to move freely and move to the fabric output position of the equipment for packing operations. Since the position of the folding fabric loading device needs to be kept fixed during fabric loading, the traveling wheels 11 need to have braking function.

[0028] This invention is simple to operate, and its application can effectively increase the fabric capacity of the fabric box, resulting in excellent performance and making it worthy of widespread promotion and application.
