Description

Technical Field

[0001] The utility model relates to cloth production equipment, in particular to a material storage rack. Background Art

[0002] In the fabric manufacturing industry, fabric is wound onto a reel after processing. Once the fabric reaches a certain thickness, it needs to be unloaded and transferred to a new reel to continue winding. To ensure continuous rewinding without stopping the machine, current reeling devices typically utilize a flip reel. After one reel has finished winding, it is simply cut and connected to the next reel to continue winding. The finished roll can then be unloaded. While this method solves the reel-changing problem, as the fabric wraps around the reel, the reel's diameter gradually increases, and the linear speed of the reel also increases. Therefore, if the angular velocity of the reel is too fast during the reeling process, the fabric can be easily torn or broken due to excessive tension. Furthermore, after reeling, the reel speed must be increased to prevent the fabric from dripping onto the ground. In order to avoid the above problems, the operator needs to frequently adjust the speed of the winding motor. This is not only cumbersome and labor-intensive, but also requires the use of more complex circuits for control. In addition, since the amplitude of adjustment required in each time period is also uneven, the adjustment is difficult and the probability of error is also high. The above problems are also easy to occur, and the quality requirements of the fabric are difficult to guarantee. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a material storage rack, which can store materials and freely control the storage amount according to needs, thereby controlling the discharge or storage of materials without constantly adjusting the winding speed and preventing the fabric from being torn or drooped.

[0004] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0005] A material storage rack comprises a frame, a cloth feed roller, a cloth discharge roller and a plurality of fixed guide rollers, wherein the cloth feed roller, the cloth discharge roller and the fixed guide rollers are rotatably mounted on the frame, and the cloth feed roller and the cloth discharge roller are respectively located on both sides of the frame. The rack is characterized in that it further comprises a translation seat, an elastic tensioning mechanism and at least one translation guide roller, wherein the elastic tensioning mechanism is fixedly mounted on the frame; the translation seat is transmission-connected to the power output end of the elastic tensioning mechanism; the translation guide roller is rotatably mounted on the translation seat, and the translation guide roller is parallel to the fixed guide roller.

[0006] In the aforementioned accumulator, the fabric enters via a fabric feed roller, alternately passes through fixed and translational guide rollers, and is then fed out by a fabric discharge roller. Typically, the angular velocity of the front feed roller is greater than that of the take-up shaft. During the initial stage of rewinding, the translational guide roller, under the action of an elastic tensioning mechanism, moves away from the fixed guide roller, and the distance between the translational guide roller and the fixed guide roller reaches its maximum. At this point, because the rewinding speed is slower than the unwinding speed, the translational guide roller is not subjected to the pressure of the rewinding fabric, allowing the fabric to be retained between the fixed and translational guide rollers as it is fed, thereby storing the fabric. As rewinding progresses, the radius of the take-up shaft gradually increases, and the rewinding speed gradually exceeds the unwinding speed. At this point, the traction force on the fabric increases, overcoming the elastic force of the elastic tensioning mechanism and causing the translational guide roller to gradually approach the fixed guide roller. Consequently, the fabric retained between the fixed and translational guide rollers is gradually drawn away, allowing the retained fabric to be discharged. During the use of this storage rack, the translation seat can automatically move according to the amount of pressure it receives, and the storage and discharge of the fabric can be automatically realized without manual adjustment and control. The fabric will not fall off in the front part of winding, and the fabric will not be subjected to too much tension and will not be torn when it is gradually pulled away by the winding shaft. There is no need to make real-time adjustments to the unwinding speed or the winding speed during the entire process.

[0007] In a preferred embodiment, the frame is a vertical frame, each of the fixed guide rollers is arranged at the upper part or the lower part of the vertical frame, and the translation guide roller is located below or above the fixed guide roller. The storage rack can be a vertical storage rack.

[0008] In a further preferred embodiment, the elastic tensioning mechanism includes a first tensioning device and two first guide rails extending vertically on the vertical mounting frame. The translation seat is in transmission connection with the power output end of the first tensioning device. The two first guide rails are respectively disposed on the left and right sides of the vertical mounting frame. The translation seat has first guide grooves at both ends thereof that match the two first guide rails. The translation seat is disposed on the first guide rails so as to be movable vertically through the first guide grooves. When a vertical storage rack is used, the translation seat can drive the translation guide roller to move vertically along the first guide rails.

[0009] In another preferred embodiment, the frame is a horizontal mounting frame, each of the fixed guide rollers is arranged at the front or rear of the horizontal mounting frame, and the translation guide roller is located at the rear or front of the fixed guide roller. According to production needs, the storage rack can also be a horizontal storage rack.

[0010] In a further preferred embodiment, the elastic tensioning mechanism includes a second tensioning device and two second guide rails extending in the front-to-back direction on the horizontal mounting frame. The translation seat is drivingly connected to the power output end of the second tensioning device. The two second guide rails are respectively disposed on the left and right sides of the horizontal mounting frame. The translation seat has second guide grooves at both ends that match the two second guide rails. The translation seat is disposed on the second guide rails so as to be movable forward and backward through the second guide grooves. When a horizontal storage rack is used, the translation seat can drive the translation guide roller to move forward and backward along the second guide rails.

[0011] In a further preferred embodiment, both the first and second tensioning devices utilize a servo cylinder or gas spring, and the translation seat is connected to the piston rod of the passive cylinder or gas spring. In the initial state, the translation seat moves along the guide rail under the action of the servo cylinder or gas spring, causing the translation guide roller to move away from the fixed guide roller and maximizing the distance between the translation guide roller and the fixed guide roller. In this state, the material storage rack primarily functions as a material storage rack. As winding progresses, the traction force exerted by the winding shaft on the fabric overcomes the elastic force of the servo cylinder or gas spring, thereby driving the translation seat along the guide rail via the translation guide roller, causing the translation guide roller to gradually approach the fixed guide roller. In this state, the material storage rack primarily functions as a material discharge rack.

[0012] In a preferred embodiment, the number of the translation guide rollers is multiple. The cloth passes through the fixed guide rollers and the translation guide rollers alternately. By using multiple translation guide rollers, more cloth can be reserved.

[0013] The beneficial effect of the utility model is that the material storage rack can store materials and can freely control the storage amount according to needs, thereby controlling the discharge or storage of materials, without the need to constantly adjust the winding speed, and the fabric will not be torn or drooped.

[0015] Figure 2 This is a structural diagram of the material storage rack in Example 2 of the present utility model. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] Example 1, as Figure 1The material storage rack shown includes a frame 1, a cloth feed roller 2, a cloth discharge roller 3, a translation seat 4, an elastic tensioning mechanism 5, a plurality of fixed guide rollers 6 and a plurality of translation guide rollers 7. The cloth feed roller 2, the cloth discharge roller 3 and each fixed guide roller 6 are rotatably mounted on the frame 1, the cloth feed roller 2 and the cloth discharge roller 3 are respectively located on both sides of the frame 1, and the elastic tensioning mechanism 5 is fixedly mounted on the frame 1; the translation seat 4 is transmission-connected to the power output end of the elastic tensioning mechanism 5; the translation guide roller 7 is rotatably mounted on the translation seat 4, and the translation guide roller 7 is parallel to the fixed guide roller 6.

[0018] In the aforementioned accumulator, fabric enters via the fabric feed roller 2, alternately passes through the fixed guide roller 6 and the translation guide roller 7, and is then fed out by the fabric discharge roller 3. Typically, the angular velocity of the front feed roller is greater than that of the take-up shaft. During the initial stage of rewinding, the translation guide roller 7, under the action of the elastic tensioning mechanism 5, moves away from the fixed guide roller 6, and the distance between the translation guide roller 7 and the fixed guide roller 6 reaches its maximum. At this point, because the rewinding speed is slower than the unwinding speed, the translation guide roller 7 is not subjected to the pressure of the rewinding fabric, and the fabric can be retained between the fixed guide roller 6 and the translation guide roller 7 as it is fed, thereby storing the fabric. As rewinding progresses, the radius of the take-up shaft gradually increases, and the rewinding speed gradually exceeds the unwinding speed. At this point, the traction force on the fabric increases, overcoming the elastic force of the elastic tensioning mechanism 5 and causing the translation guide roller 7 to gradually approach the fixed guide roller 6. Consequently, the fabric retained between the fixed guide roller 6 and the translation guide roller 7 is gradually drawn away, achieving the discharge of the retained fabric. During the use of this storage rack, the translation seat 4 can automatically move according to the amount of pressure it receives, and the storage and discharge of the cloth can be automatically realized without manual adjustment and control. The cloth will not fall off in the front section of winding, and the cloth will not be subjected to too much tension and will not be torn when it is gradually drawn away by the winding shaft. There is no need to make real-time adjustments to the unwinding speed or the winding speed during the entire process.

[0019] Frame 1 is a vertical mounting frame, and each fixed guide roller 6 is all arranged on the top of the vertical mounting frame, and translation guide roller 7 is located below the fixed guide roller 6. The storage rack can adopt a vertical storage rack.

[0020] The elastic tensioning mechanism 5 includes a first tensioning device 501 and two vertically extending first guide rails 502 mounted on the vertical mounting frame. The translating base 4 is in driving connection with the power output of the first tensioning device 501. The two first guide rails 502 are located on the left and right sides of the vertical mounting frame, respectively. The translating base 4 has first guide grooves (not visible in the figure) at each end that match the two first guide rails 502. The translating base 4 is mounted on the first guide rails 502 via the first guide grooves, allowing it to move vertically. When using a vertical storage rack, the translating base 4 can drive the translating guide rollers 7 to move vertically along the first guide rails 502.

[0021] The first tensioning device 501 utilizes a servo cylinder or gas spring, and the translation seat 4 is connected to the piston rod of the passive cylinder or gas spring. In its initial state, the translation seat 4, under the action of the servo cylinder or gas spring, moves along the guide rail, causing the translation guide roller 7 to move away from the fixed guide roller 6, and the distance between the translation guide roller 7 and the fixed guide roller 6 to reach its maximum. In this state, the accumulator primarily functions as a storage rack. As winding progresses, the traction force exerted by the winding shaft on the fabric overcomes the elastic force of the servo cylinder or gas spring, thereby driving the translation rack along the guide rail via the translation guide roller 7, gradually bringing the translation guide roller 7 closer to the fixed guide roller 6. In this state, the accumulator primarily functions as a discharge rack.

[0022] Example 2: The difference between this example and Example 1 is that: Figure 2 As shown, the frame 1' is a horizontal mounting frame, each fixed guide roller 6' is arranged at the front or rear of the horizontal mounting frame, and the translation guide roller 7' is located at the rear or front of the fixed guide roller 6'. According to production needs, the storage rack can also adopt a horizontal storage rack.

[0023] The elastic tensioning mechanism 5' comprises a second tensioning device 501' and two second guide rails 502' extending in the front-to-back direction on the horizontal mounting frame. The translating base 4' is drivingly connected to the power output end of the second tensioning device 501'. The two second guide rails 502' are located on the left and right sides of the horizontal mounting frame, respectively. The translating base 4' has second guide grooves (not visible in the figure) at each end that match the two second guide rails 502'. The translating base 4' is mounted on the second guide rails 502' via the second guide grooves, allowing for forward and backward movement. When using a horizontal storage rack, the translating base 4' drives the translation guide rollers 7' to move forward and backward along the second guide rails 502'.
