Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to an automatic feeding mechanism for release paper. Background Technology

[0002] Cutting machines are used for dividing and cutting sheet materials in various industries. They do not require any molds; they are controlled by system software and then directly cut the products. As long as the corresponding parameters are set on the operating platform, the computer transmits the corresponding instructions to the cutting machine. When the material is being collected, in order to better protect the product, a layer of release paper is usually added when the material is bundled to avoid friction between the two layers of material, which could scratch the product and cause defects.

[0003] The existing automatic feeding mechanism for release paper has defects. When the motor drives the release paper feeding tray to rotate, the release paper is fed. However, when the feeding tray rotates by the same angle, the winding diameter of the release paper on the feeding tray is different, and the length of the release paper is also different. Over time, when the feeding tray rotates by the same angle, the release paper will become shorter and shorter. This leads to the following problems: in the initial stage, too much release paper is released by the feeding tray, which easily causes the release paper to be too loose and then pile up. In the later stage, too little release paper is released by the feeding tray, which easily causes the release paper to be too tight and then break. This seriously affects the conveying efficiency and quality of the release paper. Utility Model Content

[0036] As Figures 1-5The automatic feeding mechanism of the isolation paper comprises a cabinet 1, a driving part 2, a feeding disc 3 and a buffer assembly 4; the driving part 2 is fixedly arranged on the top of the cabinet 1; the buffer assembly 4 comprises a support 41, a roller 42, an acceleration sensor 43 and a deceleration sensor 44; the support 41 is arranged on the cabinet 1; the roller 42 is rotatably arranged on the support 41 and can slide along the height direction of the support 41; the acceleration sensor 43 is arranged on the upper part of the support 41; the deceleration sensor 44 is arranged on the lower part of the support 41; the feeding disc 3 is arranged on the driving shaft of the driving part 2; the feeding disc 3 is used for storing and feeding the isolation paper into the buffer assembly 4, and the isolation paper passes through the lower surface of the roller 42; the roller 42 can trigger the acceleration sensor 43 or the deceleration sensor 44 when it slides up and down; the acceleration sensor 43 is used for controlling the acceleration of the driving part 2; the deceleration sensor 44 is used for controlling the deceleration of the driving part 2; it is to be noted that the cabinet 1 is provided with a controller; the driving part 2, the acceleration sensor 43 and the deceleration sensor 44 are electrically connected with the controller; the driving part 2 is preferably a stepping motor; the stepping motor has good dynamic response performance; it can smoothly adjust the speed in a wide speed range and has the ability of quick start and stop; it can achieve high acceleration and deceleration and adapt to frequent acceleration and deceleration; the buffer assembly 4 is arranged below the feeding disc 3 so that the feeding disc 3 can easily feed the isolation paper onto the buffer assembly 4; the support 41 is composed of two support plates; the two support plates have a gap for accommodating the roller 42; the width of the roller 42 is greater than the width of the isolation paper; the isolation paper passes through the lower surface of the roller 42 so that the roller 42 can press the isolation paper and then slide up and down under the driving of the isolation paper.

[0037] In an embodiment, it is assumed that the roller 42 is between the acceleration sensor 43 and the deceleration sensor 44 at this time; when the isolation paper is not enough to make the roller 42 rise, the roller 42 will trigger the acceleration sensor 43 so that the driving speed of the driving part 2 increases and the feeding speed of the feeding disc 3 accelerates; when the feeding speed of the isolation paper is greater than the discharging speed, the roller 42 begins to descend; since the position of the roller 42 is higher than the acceleration sensor 43 at this time, the roller 42 will trigger the acceleration sensor 43 again when it descends, so that the driving part 2 is still in the acceleration state; when the roller 42 descends to trigger the deceleration sensor 44, the driving speed of the driving part 2 begins to decrease and the feeding speed of the feeding disc 3 slows down; at this time, since the feeding speed is still greater than the discharging speed, the roller 42 will continue to descend for a distance; when the feeding speed decreases to be less than the discharging speed, the roller 42 begins to rise; the roller 42 will trigger the deceleration sensor 44 again when it rises, so that the driving part 2 is still in the deceleration state; the roller 42 continues to rise until it triggers the acceleration sensor 43, so that the driving speed of the driving part 2 accelerates; the cycle is repeated, that is, the roller 42 always does reciprocating motion within a certain range, so that the tension of the isolation paper is constant within a certain range, so that the isolation paper can be stably output.

[0038] In another embodiment, different from the above embodiment, when the roller 42 triggers the acceleration sensor 43 in the process of descending, the driving speed of the driving member 2 stops increasing and remains unchanged, at this time, the discharging speed has been greater than the discharging speed, the roller 42 continues to descend until triggering the deceleration sensor 44, and the driving member 2 starts to decelerate, and for the same reason, when the roller 42 triggers the deceleration sensor 44 in the process of ascending, the driving speed of the driving member 2 stops decreasing and remains unchanged, at this time, the discharging speed has been less than the discharging speed, the roller 42 continues to ascend until triggering the acceleration sensor 43, and the driving member 2 starts to accelerate, and the cycle is repeated, and the roller 42 also reciprocates in a certain range. Compared with the above embodiment, in this embodiment, the reciprocating range of the roller 42 is smaller, and users can adopt one of the two embodiments according to the size of the cabinet 1 and the actual situation.

[0039] The utility model discloses the beneficial effect lies in: through setting up the buffer component 4 to adjust the buffer length of the isolation paper, and the roller 42 can tension the isolation paper through the gravity of itself, to stabilize the tension of the isolation paper in the conveying process, avoid the rupture of the isolation paper caused by the tension fluctuation, and the acceleration sensor 43 and the deceleration sensor 44 can control the driving speed of the driving member 2, when the isolation paper is discharged less, the driving member 2 speed increases to speed up the discharging speed, when the isolation paper is discharged more, the driving member 2 speed reduces to slow down the discharging speed, thereby avoiding the excessive accumulation or deficiency of the isolation paper, ensuring that the isolation paper is always in the best state, and greatly improving the conveying efficiency and quality of the isolation paper.

[0040] Please refer to Figure 1 And Figure 3 In a possible implementation, the cabinet 1 is provided with a guide plate 11, which is located between the discharging disc 3 and the buffer component 4. The guide plate 11 is provided with a limiting hole 111, and the isolation paper passes through the limiting hole 111. It should be noted that the discharging disc 3 and the buffer component 4 have a certain distance, and the guide plate 11 is arranged between the discharging disc 3 and the buffer component 4, which can guide and limit the isolation paper, so that the isolation paper is not easy to twist in this range, so that the isolation paper can smoothly enter the buffer component 4, which is beneficial to improve the stability of the isolation paper conveying.

[0041] Please refer to Figure 2In a possible implementation, the upper end of the bracket 41 is provided with two guide limiters 45 on both sides, and the isolation paper enters the bracket 41 from the left guide limiter 45 and exits the bracket 41 from the right guide limiter 45. It should be noted that the two guide limiters 45 are located on both sides of the roller 42, and the isolation paper is tensioned under the weight of the roller 42, and the guide limiter 45 cooperates with the roller 42 to make the isolation paper U-shaped, and the guide limiter 45 can guide and limit the isolation paper, so that the isolation paper can smoothly adhere to the roller 42, and the setting of the guide limiter 45 is beneficial to improve the stability of the running of the caching assembly 4.

[0042] Further, the guide limiter 45 includes a stop block 451 and two cylinders 452, and the two cylinders 452 are arranged on the bracket 41 in a spaced manner, and the two ends of the stop block 451 are connected to the ends of the two cylinders 452, and the isolation paper passes between the two cylinders 452. It is easy to understand that the isolation paper generates sliding friction with the cylinder 452, and the setting of the stop block 451 can prevent the isolation paper from sliding out between the two cylinders 452, and the cylinder 452 is a middle hole structure, and the bracket 41 and the stop block 451 are both provided with through holes, and a limiting pin can be used to pass through the stop block 451, the cylinder 452 and the bracket 41 in sequence, so that the guide limiter 45 is fixed on the bracket 41, and the guide limiter 45 is simple in structure and convenient to install and disassemble.

[0043] Please refer to Figure 2 In a possible implementation, the bracket 41 is provided with a sliding hole 411 extending along the height direction of the bracket 41, and the end of the roller 42 is provided with a sliding shaft 421 extending into the sliding hole 411. It should be noted that the two supporting plates of the bracket 41 are both provided with the sliding hole 411, and the two ends of the roller 42 are also both provided with the sliding shaft 421, and the two sliding shafts 421 extend into the sliding holes 411 of the two supporting plates respectively, so that the roller 42 can slide along the extension direction of the sliding hole 411, which is beneficial to improve the sliding smoothness of the roller 42, and the sliding shaft 421 on the inner side of the roller 42 is longer, so that the sliding shaft 421 can trigger the acceleration sensor 43 and the deceleration sensor 44 during the sliding process. In other implementations, the sliding hole 411 can also be arranged on the inner side of the supporting plate of the bracket 41, and the sliding shaft 421 can be arranged on one end of the roller 42, and the other end of the roller 42 can be in sliding cooperation with the other supporting plate.

[0044] Please refer to Figure 2In a possible implementation, the two ends of the bracket 41 are respectively provided with limit sensors 46 located at the two ends of the movement path of the roller 42, and the limit sensors 46 are used to control the limit positions of the roller 42. It should be noted that the acceleration sensor 43 and the deceleration sensor 44 can ensure that the isolation paper is stably transported in normal operation, but if an accident occurs, such as the influence of the front and rear process mechanisms on the feeding speed, the driving member 2 may not be able to accelerate or decelerate in time, thereby causing the isolation paper to be broken or accumulated. The limit sensors 46 are provided to solve this problem. When the isolation paper suddenly stops feeding, the driving member 2 cannot decelerate in time, and the roller 42 will sharply drop. When the roller 42 triggers the limit sensor 46 located at the lower end of the bracket 41, the driving member 2 stops moving, so that the feeding disc 3 stops feeding, thereby preventing the isolation paper from being accumulated. When the feeding speed of the isolation paper suddenly increases, the driving member 2 cannot accelerate in time, and the roller 42 will continue to rise. When the roller 42 triggers the limit sensor 46 located at the upper end of the bracket 41, the driving member 2 accelerates rapidly, and the acceleration of the driving member 2 is increased, so as to reduce the time required for acceleration, thereby reducing the risk of the isolation paper being pulled apart by a larger tension.

[0045] Specifically, the back of the bracket 41 is sequentially provided, from top to bottom, with a limit sensor 46, an acceleration sensor 43, a deceleration sensor 44, and a limit sensor 46, and the intervals are uniform.

[0046] Please refer to Figure 2 In a possible implementation, the bracket 41 is provided with a plurality of photoelectric mounting plates 47, and the acceleration sensor 43, the deceleration sensor, and the limit sensor 46 are arranged on the photoelectric mounting plates 47. It should be noted that the photoelectric mounting plates 47 are arranged on the back of the bracket 41, that is, close to the side of the cabinet 1, and the plurality of photoelectric mounting plates 47 are uniformly arranged along the extension direction of the sliding hole 411. The photoelectric mounting plates 47 can provide a mounting basis for each sensor, so that each sensor can accurately correspond to the sliding hole 411, so that the roller 42 can pass through the sensor and trigger when sliding.

[0047] Please refer to Figure 4 In a possible implementation, the cabinet 1 is provided with a guide wheel 12 located at the right side of the buffer assembly 4, and the guide wheel 12 is used to guide the isolation paper into the feeding track (not shown in the figure) of the cabinet 1. It should be noted that the isolation paper needs to be combined with the carrier tape into the feeding track, and the guide wheel 12 is arranged between the buffer assembly 4 and the feeding track, so that the isolation paper can be guided into the feeding track after being discharged from the buffer assembly 4, which is conducive to improving the stability of the isolation paper transportation.

[0048] Further, the guide wheel 12 comprises a support column 121, an inner diameter check ring 122 and a width tube position wheel 123; the support column 121 is vertically arranged on the cabinet 1; the width tube position wheel 123 is rotatably arranged on the support column 121; the inner diameter check ring 122 is sleeved on the support column 121, and the number of the inner diameter check ring 122 is two and is respectively located at two ends of the width tube position wheel 123. It should be noted that the isolation paper enters the material conveying track through the width tube position wheel 123, the width tube position wheel 123 can limit the isolation paper in the width direction, the support column 121 can provide a mounting base for the width tube position wheel 123, and the width tube position wheel 123 can extend outward, so that the two sides of the width tube position wheel 123 correspond to the buffer assembly 4 and the material conveying track respectively, so that the isolation paper will not be bent in the conveying process.

[0049] Please refer to Figure 5 In a possible implementation, the top of the cabinet 1 is provided with a mounting base 13, and the driving member 2 is arranged on the mounting base 13. It should be noted that the mounting base 13 can provide a mounting base for the driving member 2, and the driving member 2 and the material feeding disc 3 are respectively located at two sides of the mounting base 13, so as to improve the balance. The mounting base 13 is triangular, and the mounting base 13 can also provide a certain height and distance for the material feeding disc 3, so that the material feeding disc 3 has a certain gap with the cabinet 1, so as to avoid scratching the cabinet 1 when the material feeding disc 3 rotates.

[0050] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application belong to the scope of protection required by the present application.
