[0013] The working principle and beneficial effects of the utility model are:
[0014] The bracket is used to receive the paper delivered by the production line. When the number of papers on the bracket reaches the specified amount, the lifting frame descends. A distance sensor is set under the bracket. When the lifting frame descends, the distance sensor detects the distance between the lower receiving plate or the stacked paper pile in real time. When the appropriate distance is reached, the distance sensor transmits a signal to the rotating drive, and the rotating drive drives the bidirectional screw to rotate. Because the two sections of the thread on the bidirectional screw have the same rotation direction and opposite pitch, the rotation of the bidirectional screw will drive the two brackets to slide inward or outward synchronously. When the two brackets slide outward synchronously, they can no longer support the paper pile. The paper pile falls into the stacked paper pile below due to its own weight, completing the stacking of the paper. By setting a distance sensor, the height of the paper pile falling can be reasonably controlled, and the problem of the paper pile spreading caused by the high height of the paper pile can be effectively avoided. The bracket adopts the form of horizontal sliding. Compared with the swing opening method, the vertical space required by the bracket is smaller, which allows the bracket to be opened at a position closer to the receiving plate below. In addition, the two brackets can be controlled to open or close by the bidirectional screw, and the action of releasing the paper stack can be flexibly controlled. The electrical connection between the distance sensor and the rotating drive member is a conventional system program control method in the prior art, which will not be repeated here.

[0025] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, a paper stacking device is proposed, including a frame 1, a lifting frame 2, a bracket 3, a distance sensor 4, a bidirectional screw 5, a rotating drive member 6 and a receiving plate 7, the lifting frame 2 is slidably arranged on the frame 1, the bracket 3 is slidably arranged on the lifting frame 2, two of the brackets 3 are symmetrically arranged on the left and right, the distance sensor 4 is arranged at the bottom of the bracket 3, the bidirectional screw 5 is rotatably arranged on the lifting frame 2, the bidirectional screw 5 has two sections of threads with opposite rotation directions and the same pitch, the two brackets 3 are respectively threadedly connected to the two sections of threads, the rotating drive member 6 is arranged on the lifting frame 2, and is drivingly connected to the bidirectional screw 5, the distance sensor 4 is electrically connected to the rotating drive member 6, and the receiving plate 7 is arranged on the frame 1, located below the bracket 3.
[0026] In this embodiment, the bracket 3 is used to receive the paper delivered by the production line. When the number of papers on the bracket 3 reaches the specified number, the lifting frame 2 descends. A distance sensor 4 is arranged below the bracket 3. When the lifting frame 2 descends, the distance sensor 4 detects the distance between the lifting frame 2 and the receiving plate 7 or the stacked paper pile below in real time. When the appropriate distance is reached, the distance sensor 4 transmits a signal to the rotating drive member 6, and the rotating drive member 6 drives the bidirectional screw 5 to rotate. Because the two sections of the thread on the bidirectional screw 5 have the same rotation direction and opposite pitch, the rotation of the bidirectional screw 5 will drive the two brackets 3 to slide inward or outward synchronously. When the two brackets 3 slide outward synchronously, they can no longer support the paper pile. The paper pile falls into the stacked paper pile below due to its own weight, completing the stacking of the paper. By setting the distance sensor 4, the height of the paper pile falling can be reasonably controlled, and the problem of the paper pile being scattered due to the high height of the paper pile can be effectively avoided. The bracket 3 adopts the form of horizontal sliding. Compared with the swing opening mode, the bracket 3 requires a smaller vertical space, so that the bracket 3 can be opened at a position closer to the lower receiving plate 7. In addition, the two brackets 3 can be controlled to open or close by the bidirectional screw 5, and the action of releasing the paper stack can be flexibly controlled. The electrical connection between the distance sensor 4 and the rotating drive member 6 is a conventional system program control mode in the prior art, which will not be described in detail here.
[0027] It also includes a supporting box 8, a slider 9 and a supporting roller 10. The supporting box 8 is slidably arranged on the bracket 3. The supporting box 8 has the same sliding direction as the bracket 3. The slider 9 is slidably arranged in the supporting box 8. The supporting roller 10 is rotatably arranged on the slider 9. The top surface of the supporting box 8 has a through hole 11. After the slider 9 slides, the supporting roller 10 protrudes out of or cancels protruding out of the through hole 11.
[0028] After the two brackets 3 are close to each other, the ends of the two supporting boxes 8 abut against each other, and also include a spring 12, the two ends of the spring 12 act on the slider 9 and the inner wall of the supporting box 8 respectively, for providing a force for the supporting roller 10 to protrude from the through hole 11, the bracket 3 has a pushing arc surface 13, and the slider 9 has a thrust inclined surface 14, after the bracket 3 slides, the pushing arc surface 13 abuts against or cancels the abutment against the thrust inclined surface 14, for providing or canceling the force for compressing the spring 12.
[0029] In this embodiment, in order to avoid friction between the bracket 3 and the bottom surface of the paper stack when sliding, a supporting box 8 is further provided, and the interior of the supporting box 8 is hollow.
[0030] When it is necessary to receive the paper delivered by the production line, the two brackets 3 slide inward synchronously, driving the two supporting boxes 8 to approach each other until they abut against each other. After the two supporting boxes 8 abut against each other, the brackets 3 can continue to slide inward, that is, the slider 9 is pressed down by the force of the pushing arc surface 13 abutting against the supporting inclined surface 14, compressing the spring 12, so that the supporting roller 10 retracts into the through hole 11, ensuring that the top surface of the supporting box 8 is smooth, which is convenient for receiving the paper.
[0031] When the received paper stack needs to be transferred to the receiving plate 7 below, the lifting frame 2 first descends and stops at a suitable height with the help of the distance sensor 4, and then the two brackets 3 slide outward synchronously. During the sliding of the bracket 3 outward, the pushing arc surface 13 will first move away from the supporting inclined surface 14. After the pushing arc surface 13 is separated from the supporting inclined surface 14, the slider 9 is reset upward under the elastic force of the spring 12, so that the supporting roller 10 protrudes out of the through hole 11 and contacts the bottom surface of the paper stack. As the bracket 3 continues to slide outward, it will drive the supporting box 8 to slide outward, and the supporting roller 10 will roll on the bottom surface of the paper stack, thereby reducing sliding friction and avoiding damage to the surface quality of the bottom surface of the paper stack.
[0032] It also includes a clamping plate 15 , which is slidably disposed on the bracket 3 , and there are two clamping plates 15 , which are respectively located on both sides of the supporting box 8 .
[0033] In this embodiment, the two brackets 3 are both slidably provided with clamping plates 15, which are driven by a cylinder installed on the bracket 3. The two clamping plates 15 slide inward synchronously to clamp the paper stack in the middle and gather the papers to the middle. Every time a layer of paper is added to the bracket 3, the clamping plates 15 repeat the clamping action, which plays a shaping role on the paper stack and ensures a good stacking effect of the paper stack.
[0034] The baffle 16 is also included, and the baffle 16 is arranged on a side of the supporting box 8 away from the paper supply direction.
[0035] In this embodiment, in order to prevent the paper from passing over the support box 8 due to inertia when the production line is fed, a baffle 16 is provided at the end of the support box 8. The baffle 16 is located on the side away from the direction of the paper feed, and can block the paper to the same position to ensure the neatness of the paper stack.
[0036] There are multiple material receiving plates 7 , and the multiple material receiving plates 7 are parallel to each other, and there are intervals between the multiple material receiving plates 7 .
[0037] In this embodiment, a plurality of receiving plates 7 are arranged in parallel, and there are intervals between adjacent receiving plates 7, and the intervals can facilitate manual or forklift transportation of paper stacks.
[0038] It also includes a conveyor belt 17 , which is rotatably arranged on the frame 1 . The conveyor belt 17 is located in front of the supporting box 8 and is used to transport paper to the supporting box 8 .
[0039] The machine frame 1 further comprises a guide plate 18 , wherein the guide plate 18 is arranged on the frame 1 , and there are two guide plates 18 , which are respectively located on both sides of the conveyor belt 17 .
[0040] In this embodiment, the conveyor belt 17 is located between the paper production line and the bracket 3, and is used for the transition between the production line and the bracket 3. The conveyor belt 17 can convey the paper to the bracket 3. The guide plates 18 on both sides of the conveyor belt 17 can guide and correct the paper to ensure that the paper is conveyed in the forward direction. The end of the guide plate 18 has an inclined section to facilitate the entry of the paper.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
