Description

Technical Field

[0001] The utility model relates to the field of paper counting, in particular to a counting device used for paper production. Background Art

[0002] In paper production, it is necessary to go through processes such as material selection, pulping, screening, pressing, drying, surface treatment, cutting, and packaging. The raw materials are made into qualified pulp through the material selection, pulping, and screening processes, and a paper layer is formed on the screen. After processes such as pressing, drying and surface treatment, larger-sized paper is produced. In order to meet paper sales needs, large-sized paper needs to be cut into small-sized paper through the cutting process, and the small-sized paper needs to be packaged.

[0003] After the cutting equipment cuts the small sheets, they are transported via a conveyor belt. The small sheets reach the end of the conveyor belt, detach, and are stacked on a receiving board. The stacked sheets are then packaged and ready for sale. To ensure that each package contains the same number of sheets, the sheets are counted.

[0004] Currently, there are paper counting devices on the market. For example, a paper counting device disclosed in a Chinese patent with patent publication number CN105809240A includes: a counting unit for counting and identifying paper; an accumulation unit for accumulating paper counted by the counting unit; a rotating guide component for accumulating paper counted by the counting unit in the accumulation unit; a shutter for closing the opening of the accumulation unit; a shutter drive unit for driving the shutter; a control unit for controlling the shutter drive unit; a placement unit for placing paper to be counted by the counting unit; a first paper detection unit for detecting whether paper is placed in the placement unit; a rejection unit for receiving paper transmitted from the counting unit and identified as rejected paper by the counting unit; and a second paper detection unit for detecting whether paper is accumulated in the rejection unit. Even if the first paper detection unit detects that there is no paper in the placement unit, but the second paper detection unit detects that there is paper in the rejection unit, the control unit controls the shutter drive unit so that the shutter continues to close the opening of the accumulation unit.

[0005] While the counting device provided in the aforementioned patent is capable of counting paper sheets, it is inconvenient for counting the sheets of paper being moved and accumulated at the end of the conveyor belt. This requires a worker to count each sheet individually to ensure that each package has the same number of sheets, which is not conducive to efficient paper packaging. Alternatively, the thickness of the entire stack of paper is measured and divided by the thickness of a single sheet to determine the number of sheets in each package. Both this method and manual counting methods are subject to significant errors. Utility Model Content

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0026] Example 1

[0027] In order to accurately count the number of stacked papers and improve the efficiency of paper packaging, this embodiment provides a counting device for paper production, which can accurately count the moving papers so that each package contains the same number of papers.

[0028] like Figure 1 、 Figure 5As shown, specifically, the counting device includes a counting assembly 4, which includes a first support plate group 42, a second support plate group 43, an infrared receiver 41, an infrared transmitter 45, and a counter 5. The first support plate group 42 and the second support plate group 43 are arranged vertically and located between a paper conveyor belt 1 and a receiving plate 2. The conveyor belt 1 lowers multiple sheets of cut paper to the receiving plate 2, where they are accumulated. In the prior art, the receiving plate 2 is also provided with a blocking structure. Since the conveyor belt 1 and the receiving plate 2 are both prior art, they are not described in detail here and are simply illustrated in the accompanying drawings. The number of infrared receivers 41 and infrared emitters 45 is equal, and they are evenly distributed on the sides of the first support plate group 42 and the second support plate group 43. At the same time, the infrared receivers 41 and the infrared emitters 45 are opposite to each other and distributed on the upper and lower sides of the paper. At the same time, the infrared receivers 41 and the infrared emitters 45 are electrically connected to the counter 5. During specific operation, when an object passes through the infrared receiver 41 and the infrared emitter 45, the infrared light is blocked, and the output voltage of the infrared receiver 41 changes. This changed voltage signal is amplified and processed to form a counting pulse to trigger a decimal counter 5, thereby realizing the counting statistics of the document. Therefore, when the paper passes through the infrared receiver 41 and the infrared emitter 45, it can be counted on the counter 5. The counter 5 can also be electrically connected to the control system of paper production so as to be integrated into the entire production process. The purpose of providing multiple infrared receivers 41 and infrared transmitters 45 is to adapt to existing production conditions. This is because, when cutting large-sized paper, multiple small-sized paper can be produced simultaneously. Then, under the action of the conveyor belt 1, the multiple small-sized paper moves to the receiving plate 2. At this time, the multiple infrared receivers 41 and infrared transmitters 45 can be used to count the paper on multiple conveyor tracks. Of course, a single infrared receiver 41 and infrared transmitter 45 can also be provided. This is because multiple small-sized paper is cut simultaneously and transported via the same conveyor belt 1. Therefore, monitoring the paper on one conveyor track is equivalent to counting the paper on other conveyor tracks. However, providing a single infrared receiver 41 and infrared transmitter 45 is not conducive to responding to emergencies.

[0029] like Figure 3 、 Figure 4As shown, to achieve adjustable placement of the infrared receiver 41 and infrared emitter 45, the first support plate group 42 and the second support plate group 43 include a base plate 431 and an extrusion plate 432. The sidewalls of the base plate 431 are provided with a filling slot 433, and the sidewalls of the filling slot 433 are provided with a locking slot 434. The extrusion plate 432 is bolted to the filling slot 433. A locking slot 434 may also be provided on the side of the extrusion plate 432 adjacent to the locking slot 434. Furthermore, a snap plate 411 is provided on the side of each of the infrared receiver 41 and the infrared emitter 45. The snap plate 411 is located within the space formed by the locking slot 434 and the extrusion plate 432. With the cooperation of the snap plate 411 and the locking slot 434, the infrared receiver 41 and the infrared emitter 45 can be stably placed on the sides of the first support plate group 42 and the second support plate group 43. By turning the bolts, the extrusion plate 432 is moved away from the base plate 431, releasing the restraint of the snap plate 411. This allows the infrared receiver 41 and infrared emitter 45 to move along the length of the first support plate assembly 42 and the second support plate assembly 43, allowing the positions of the infrared receiver 41 and infrared emitter 45 to be adjusted. Furthermore, the extrusion plate 432 can be removed to expose the snap plate 411, facilitating replacement or addition / removal of the infrared receiver 41 and infrared emitter 45.

[0030] like Figure 1 、 Figure 2 As shown, in order to ensure a stable connection between the first support plate group 42 and the second support plate group 43, a connecting rod 44 is provided at the ends of the first support plate group 42 and the second support plate group 43. The top of the connecting rod 44 is fixedly connected to the second support plate group 43, and the lower end is provided through the through-hole 421 of the first support plate group 42. A second thread 442 is provided at the lower end of the connecting rod 44. A second internally threaded tube 443 is threadedly sleeved on the second threaded rod 442. The top of the second internally threaded tube 443 contacts the bottom surface of the first support plate group 42. At the same time, the connecting rod 44 is connected to the bracket of the conveyor belt 1 through the crossbeam 3. With the cooperation of the connecting rod 44 and the crossbeam 3, the first support plate group 42 and the second support plate group 43 are stably arranged relative to the conveyor belt 1. In addition, the relative position of the first support plate group 42 and the second support plate group 43 can be adjusted by rotating the second internally threaded tube 443.

[0031] Example 2

[0032] like Figure 6 、 Figure 7As shown, based on Example 1, in order to adjust the position of the infrared receiver 41 and the infrared transmitter 45 relative to the conveyor belt as required, a slot 31 is provided at the end of the crossbeam 3, an end plate 32 is provided on the side of the crossbeam 3, and an insert plate 33 is provided on the side of the end plate 32. A bolt is threaded through the insert plate 33 and inserted into the slot 31. The end of the bolt can press against the side wall of the slot 31. The insert plate 33 and the slot 31 provide convenient adjustment of the position of the end plate 32 relative to the crossbeam 3 while achieving a stable connection between the end plate 32 and the crossbeam 3. A mounting hole 35 is provided on the end plate 32. A first internally threaded tube 34 is provided through the mounting hole 35 and is connected to the mounting hole 35 by a bearing. A first thread 441 is provided in the middle of the connecting rod 44. The first internally threaded tube 34 is threadedly sleeved on the middle of the connecting rod 44. By rotating the first internally threaded tube 34, the connecting rod 44 can be controlled to rise and fall relative to the crossbeam 3, thereby adjusting the height of the infrared receiver 41 and the infrared transmitter 45.

[0033] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
