Description

Technical Field

[0001] The utility model belongs to the technical field of artificial leather production, and particularly relates to a quick-response storage device for sizing. Background Art

[0002] As a soft product, artificial leather has semi-finished products in each process that are wound and circulated on a steel core bar. Whether it is a foaming furnace production line or a surface printing production line, in the unwinding machine, in order to ensure the continuous feeding of the assembly line, the tail of the previous roll is aligned with the leather surface of the first roll of the next roll, and the oblique cut and sewing are required, which takes about three minutes. Based on the production line's 30 meters per minute, no less than 90 meters of artificial leather semi-finished products need to be stored. Therefore, the storage capacity of the storage rack directly affects the production speed of the production line (the process requires that the speed cannot be reduced when changing rolls). In recent years, with the acceleration of the production line, the storage capacity of the storage rack must also be increased, from the original 90 meters to 150-180 meters. The general solution is to re-order extended storage racks. However, the extension of the storage rack takes up a larger area and causes the shift of the entire production line, wasting manpower and material resources. In addition, the current storage racks generally use upper-moving and lower-fixed storage devices, which can complete the storage during roll change without any problems. However, if there is an abnormal speed change during production, since only the upper guide roller group moves, the response speed is slow, which will affect the stability of the feeding tension.

[0009] An upper guide roller is provided between the rearmost upper left mounting seat and the rearmost upper right mounting seat, and a plurality of upper guide rollers are rotatably provided between the other corresponding left and right upper left mounting seats. The upper guide rollers are arranged in multiple layers in the height direction, with one upper guide roller on the bottom layer and two upper guide rollers on the other layers.

The upper left and lower left lifting drive mechanisms of the present invention share a common guide rail and rack on their front and rear sides; the upper right and lower right lifting drive mechanisms share a common guide rail and rack on their front and rear sides.

[0016] The utility model has three working states: a normal working state (small wrap angle), a flattened state (large wrap angle, balanced with friction force) and a material storage state.

[0017] The specific working process of the utility model in normal working state is as follows: When the production line is operating normally, the upper left movable guide roller frame, the upper right movable guide roller frame, and the upper guide roller move downward to the middle of the three-dimensional frame, and the lower left movable guide roller frame, the lower right movable guide roller frame, and the lower guide roller move downward to the middle of the three-dimensional frame. The four servo motors are locked, and the gears and racks engage to achieve height positioning. At this time, the upper left mounting seat is located between the two adjacent lower left mounting seats, and the upper right mounting seat is located between the two adjacent lower right mounting seats. That is, the upper guide rollers of the multiple layers and the lower guide rollers of the multiple layers are in a horizontal state. At this time, the wrap angle between the artificial leather semi-finished product and each guide roller is mostly relatively small, and the friction is low, which is suitable for normal operation.

[0018] The specific working process of the utility model in the flattened state is as follows: the four servo motors are started, and the two upper servo motors respectively drive the coaxially connected transmission rods to rotate. The front and rear sides of the transmission rods respectively drive the wheel shaft and cylindrical gear to rotate through the bevel gear pair. The cylindrical gear rotates upward on the two racks. The annular groove in the middle of the cylindrical gear slides downward along the guide rail, providing an effective guiding and limiting function. The upper left and upper right movable guide roller frames and the upper guide roller move upward simultaneously. At the same time, the two lower servo motors respectively drive the coaxially connected transmission rods to rotate. The front and rear sides of the transmission rods respectively drive the wheel shaft and cylindrical gear to rotate through the bevel gear pair. The cylindrical gear rotates downward on the two racks. The annular groove in the middle of the cylindrical gear slides downward along the guide rail, providing an effective guiding and limiting function. The lower left and lower right movable guide roller frames and the lower guide roller move downward simultaneously. When the bottom layer of the multi-layer upper guide rollers and the top layer of the multi-layer lower guide rollers are in a horizontal corresponding state, the four servo motors are turned off. At this time, the wrap angle between the artificial leather semi-finished product and each guide roller is relatively large, the artificial leather semi-finished product is flattened, and the friction between the artificial leather semi-finished product and the guide rollers is also moderate, which is suitable for the flattening operation of the artificial leather semi-finished product.

[0019] The storage process of the present invention is specifically as follows: the foaming furnace slows down. Since the unwinding speed does not change, the artificial leather semi-finished product will relax and the tension will decrease. The tension detection sensor sends data to the controller. The controller simultaneously sends a start signal to the four servo motors. The two upper servo motors drive the upper left movable guide roller frame, the upper right movable guide roller frame and the upper guide roller to move upward to a predetermined highest position at the same time. The two lower servo motors drive the lower left movable guide roller frame, the lower right movable guide roller frame and the lower guide roller to move downward to a predetermined highest position at the same time. The artificial leather semi-finished product also maintains a constant tension and is stored between the upper guide roller and the lower guide roller to complete the maximum storage capacity.

[0020] The present invention can also adjust the conveying tension of the artificial leather semi-finished product in real time. The specific process is as follows: when the foaming furnace slows down (or speeds up), the unwinding speed does not change, the artificial leather semi-finished product will relax (or be tightened), the tension will decrease (or increase), and the tension detection sensor will send the detection data to the controller. The controller will send a signal to the servo motor after calculation. The servo motor outputs a rotation angle, and the gear will rise or fall a certain distance along the rack. When the upper movable guide roller frame rises and the lower movable guide roller frame falls at the same time, the artificial leather semi-finished product is tensioned and the tension increases. Conversely, when the upper movable guide roller frame falls and the lower movable guide roller frame rises, the tension decreases. In this way, the artificial leather semi-finished product always runs under the set tension, and the artificial leather semi-finished product will not be stretched due to excessive tension, nor will it be wrinkled due to too little tension.

[0021] In summary, the present invention provides a large storage capacity storage device without requiring additional length. By employing multiple layers of guide rollers arranged in an isosceles triangle, the density of semi-finished artificial leather products passing around the upper and lower guide rollers is increased, thereby saving space and making the structure more compact. Taking three layers of guide rollers as an example, the storage capacity is approximately 3-3.2 times the storage capacity of materials of the same specification. This invention cleverly solves the problem of increasing storage capacity while maintaining the same space, while also ensuring a constant tension in the semi-finished product feed during storage and providing a flattening function for the semi-finished artificial leather. More importantly, the present invention utilizes upper and lower floating storage guide roller frames that operate simultaneously, resulting in a short storage time and a rapid response to tension changes. This ensures tension stability throughout the entire production line during production, thereby guaranteeing the production quality of high-end artificial leather. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The utility model has three working states: a normal working state (small wrap angle), a flattened state (large wrap angle, balanced with friction force) and a material storage state.

[0044] The specific working process of the present invention in normal working state is as follows: when the production line is operating normally, the upper left movable guide roller frame 2, the upper right movable guide roller frame 3 and the upper guide roller 10 move downward to the middle of the three-dimensional frame 1, the lower left movable guide roller frame 4, the lower right movable guide roller frame 5 and the lower guide roller 11 move downward to the middle of the three-dimensional frame 1, the four servo motors 12 are locked, and the gear and rack 23 are engaged to achieve height positioning. At this time, the upper left mounting seat 8 is located between the two adjacent lower left mounting seats 6, and the upper right mounting seat 9 is located between the two adjacent lower right mounting seats 7, that is, the upper guide rollers 10 of the multiple layers and the lower guide rollers 11 of the multiple layers are in a horizontal corresponding state. At this time, the wrap angles between the semi-finished artificial leather product 26 and each guide roller are mostly relatively small, and the friction is small, which is suitable for normal working operation. Figure 6 shown.

[0045] The specific working process of the present invention in the flattened state is as follows: four servo motors 12 are started, the two upper servo motors 12 respectively drive the coaxially connected transmission rods 14 to rotate, the front and rear sides of the transmission rods 14 respectively drive the wheel shaft 19 and the cylindrical gear 20 to rotate through the bevel gear pair, the cylindrical gear 20 rotates upward on the two racks 23, and the annular groove 21 in the middle of the cylindrical gear 20 slides downward along the guide rail 18, playing a good guiding and limiting role, and the upper left movable guide roller frame 2, the upper right movable guide roller frame 3 and the upper guide roller 10 move upward at the same time. At the same time, the two servo motors 12 at the bottom respectively drive the coaxially connected transmission rod 14 to rotate. The front and rear sides of the transmission rod 14 respectively drive the wheel shaft 19 and the cylindrical gear 20 to rotate through the bevel gear pair. The cylindrical gear 20 rotates downward on the two racks 23. The annular groove 21 in the middle of the cylindrical gear 20 slides downward along the guide rail 18, playing a good guiding and limiting role. The lower left movable guide roller frame 4, the lower right movable guide roller frame 5 and the lower guide roller 11 move downward at the same time. When the bottom layer of the multi-layer upper guide roller 10 and the top layer of the multi-layer lower guide roller 11 are in a horizontal corresponding state, the four servo motors 12 are turned off. At this time, the wrap angle between the artificial leather semi-finished product 26 and each guide roller is relatively large, and the artificial leather semi-finished product 26 is flattened. The friction between the artificial leather semi-finished product and the guide roller is also moderate, which is suitable for the flattening operation of the artificial leather semi-finished product 26. Figure 7 shown.

[0046] The storage process of the present invention is as follows: the foaming furnace slows down. Since the unwinding speed does not change, the artificial leather semi-finished product 26 will relax and the tension will decrease. The tension detection sensor sends data to the controller. The controller sends a start signal to the four servo motors 12 at the same time. The two upper servo motors 12 drive the upper left movable guide roller frame 2, the upper right movable guide roller frame 3 and the upper guide roller 10 to move upward to the predetermined highest position at the same time. The two lower servo motors 12 drive the lower left movable guide roller frame 4, the lower right movable guide roller frame 5 and the lower guide roller 11 to move downward to the predetermined highest position at the same time. The artificial leather semi-finished product 26 also maintains a constant tension and is stored between the upper guide roller 10 and the lower guide roller 11, completing the maximum storage capacity. Figure 8 shown.

[0047] The present invention can also adjust the conveying tension of the artificial leather semi-finished product 26 in real time. The specific process is as follows: when the foaming furnace slows down (or speeds up), since the unwinding speed does not change, the artificial leather semi-finished product 26 will relax (or be tightened), and the tension will decrease (or increase). The tension detection sensor will send the detection data to the controller, and the controller will send a signal to the servo motor 12 after calculation. The servo motor 12 outputs a rotation angle, and the gear will rise or fall a certain distance along the rack 23. When the upper movable guide roller frame rises and the lower movable guide roller frame falls at the same time, the artificial leather semi-finished product 26 is tensioned and the tension increases. Conversely, when the upper movable guide roller frame falls and the lower movable guide roller frame rises, the tension decreases. In this way, the artificial leather semi-finished product 26 always runs under the set tension, and the artificial leather semi-finished product 26 will not be narrowed due to excessive tension, nor will it be wrinkled due to too little tension.
