Description

Technical Field

[0001] The utility model relates to the technical field of paper counting machines, in particular to a double-head paper counting machine. Background Art

[0002] A paper counting machine is a device used to count stacked papers, such as test papers for students' exams. Zero error is required during printing and shipment before shipment. The traditional paper counting method using manual counting is prone to errors, so a paper counting machine is needed. Among the current paper counting machines, the best paper counting method is to use double paper counting machines for repeated counting. Only when the multiple data of the double paper counting machines match can the paper be shipped. However, purchasing two paper counting machines will increase the cost on the one hand, and it will be troublesome to operate on the other hand. The paper to be counted needs to be moved back and forth between the two paper counting machines. Therefore, a double-head paper counting machine has been developed on the market, that is, a paper counting machine with two paper counting heads, which are arranged on the left and right sides. After counting on one side, the paper is moved back and forth by rollers. Continue counting on the right side. This device still has the problem of inconvenience, and the distance between the two paper counting heads cannot be adjusted at any time for papers of different sizes. When developing this double-head paper counting machine, our R&D team also found a problem, that is, if one of the paper counting heads needs to be moved, how to hide the middle support plate? Because the paper counting head needs to be extended to count paper, if the support plate passes directly under the paper counting head, it will conflict with the components of the paper counting head. Therefore, after research and development and continuous improvement, a double-head paper counting machine is provided here, which can count with two paper counting heads at the same time to achieve data synchronization, and can also move papers of different sizes. The support plate mechanism is also designed so as not to affect the movement of the paper counting head. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] refer to Figures 1 to 8 :

[0027] The utility model discloses a double-head paper counting machine, including a frame 1, on which an operating panel 11 and a mounting frame 12 are arranged, the operating frame is used for placing paper to be counted on a daily basis, the paper to be counted is stacked and laid flat, in order to facilitate the movement of the paper to be counted, an air duct system is also arranged in the structure, an air outlet 111 is arranged on the operating panel 11, and the wind blowing upward can reduce the friction between the paper to be counted and the operating panel 11 when the paper to be counted moves, specifically, a first paper counting device 2 and a second paper counting device 3 are installed on the mounting frame 12, wherein the first paper counting device 2 and the second paper counting device 3 are respectively used The first paper counting device 2 is used to count one end of the paper, and one end of the first paper counting device 2 has a sliding mechanism 4 that drives it to move relative to the second paper counting device 3, and the second paper counting device 3 is installed in a fixed form. The first paper counting device 2 and the second paper counting device 3 here are not limited to the left or right orientation, but refer to one of the two paper counting devices. Specifically, one side of the operating panel 11 is also provided with a support plate mechanism 5 for supporting or lifting the inner side of the paper to be counted during the paper counting process. The support plate mechanism 5 includes a support plate 51 and a guide rail 52. The guide rail 52 is distributed along the sliding direction of the first paper counting device 2, that is, it is distributed in parallel along the direction of the connecting line of the two paper counting devices. One side of the support plate 51 is fixedly connected to the first paper counting device 2, and the other side can slide along the guide rail 52 in conjunction with the movement of the first paper counting device 2. In this way, when the first paper counting device 2 slides under the cooperation of the sliding mechanism 4, the support plate 51 in the support plate mechanism 5 also moves with the first paper counting device 2. The guide rail 52 includes a smooth end 521 and a sinking end 522. One side of the second paper counting device 3 has a support plate 51 for entering the sinking end. Specifically, the smooth end 521 is located in the horizontal direction, and the sunken end 522 is located near the guide rail 52 where the lower end of the second paper counting device 3 and the smooth end 521 transition downward in an arc. When the support plate 51 moves with the first paper counting device 2, the excess support plate 51 enters from the avoidance opening 201, and the sunken end 522 has the characteristic of arc transition, so the forward direction of the support plate 51 can be changed. Of course, in some application scenarios, as long as the box space of the paper counting machine is large enough, the support plate 51 can continue to move forward after sinking to avoid the head of the paper counting machine.

[0028] Specifically, the support plate 51 includes a chain plate 511 and a guide head 512, and a plurality of chain plates 511 are hinged front and rear to form a rotatable plate chain structure, wherein each chain plate 511 is fixedly connected to a guide head 512 at the lower end of a side close to the guide rail 52, and the guide rail 52 is provided with a slide groove 523 for limiting the sliding of the guide head 512. Preferably, the guide head 512 is preferably made of a counterweight component, so that each chain plate 511 can always slide close to the guide rail 52. As an alternative implementation scheme, the guide head 512 can be replaced with a pulley, and the guide rail 52 can be replaced with a pulley groove matching the pulley, and the pulley slides in the pulley groove.

[0029] Specifically, the first paper counting device 2 includes a first paper counting head 21, a first pressing plate 22, a first paper counting angle plate 23 and a first paper counting position 24, wherein the first paper counting head 21 is located inside the first paper counting device 2, and its paper counting end reaches from the first paper counting position 24 to the upper inner side of the first paper counting angle plate 23 for counting paper, and the first paper counting position 24 is formed by the spacing area of ​​two vertical plates arranged at right angles, and the first pressing plate 22 can be slidably arranged above the paper counting position up and down, and the second paper counting device 3 includes a second paper counting head 31, a second pressing plate 32, a second paper counting angle plate 33 and a second paper counting position, wherein the second paper counting head 31 is located inside the second paper counting device 3, and its paper counting end reaches from the second paper counting position to the upper inner side of the second paper counting angle plate 33 for counting paper, and the second pressing plate 32 can be slidably arranged above the paper counting position, wherein one end of the support plate 51 is connected and fixed to the fixed structure of the first paper counting angle plate 23 or the lower end of the first paper counting position 24, and the The operating panel 11, the support plate 51, the first paper counting angle plate 23 and the second paper counting angle plate 33 are located on the same horizontal plane. This arrangement is one of the improved features of the utility model. For large-sized paper, such as newspapers, when the two ends need to be counted, the area close to the inner side of the paper counting machine head will be suspended, so the support plate mechanism 5 is needed to lift it, and the support plate mechanism 5 will affect the movement of the first paper counting device 2, so it is necessary to set an avoidance space for the support plate mechanism 5 when it moves. The support plate 51 in the support plate mechanism 5 has a smooth end 521 and a sunken end 522, and the smooth end 521 is located on the same horizontal plane as the operating panel 11, the first paper counting angle plate 23 and the second paper counting angle plate 33. Of course, when the two paper counting machine heads are completely close together, the support plate 51 completely enters the avoidance space, that is, enters the lower space through the avoidance opening 201. It should be understood that the length of the sunken end 522 of the guide rail 52 is not limited, and the shape is also not limited.

[0030] Specifically, in order to save the space at the bottom occupied by the pallet 51 when entering the avoidance space, a design that allows the pallet 51 to circulate is added here. Specifically, a buffer component 6 is also provided at the lower end of the avoidance opening 201. The buffer component 6 is used to receive the pallet 51 after entering the avoidance opening 201 and adjust its sliding direction. Preferably, the buffer component 6 is located at the lower end of the sinking end 522 and is parallel to the tangent of the exit section of the sinking end 522. When the pallet 51 reaches the buffer component 6, also due to the gravity factor, the end of the pallet 51 will slide downward obliquely in the opposite direction along with the buffer component 6, thereby saving the space occupied by the pallet 51 in the avoidance space.

[0031] Preferably, the buffer component 6 has an upper inclined plate 61, which just corresponds to the position of the avoidance opening 201 and can change the forward direction of the sliding support plate 51. The upper inclined plate 61 can play a guiding role.

[0032] Specifically, the sliding mechanism 4 includes a slide rail 41, a slider 42, a slider nut 43, a screw rod 44 and a drive motor 45, wherein the slide rail 41 is installed on the mounting frame 12, the slider 42 is installed on the outer side of the bottom of the first paper counting device 2 and slides with the slide rail 41, and the slider nut 43 is installed in the middle of the bottom of the first paper counting device 2 and is screw-driven with the drive motor 45 through the screw rod 44.

[0033] Specifically, the upper ends of the first paper counting device 2 and the second paper counting device 3 are both provided with a vertical motor 202 for driving the first pressing plate 22 or the second pressing plate 32 to move up and down. The first pressing plate 22 and the vertical motor 202 can drive the first or second pressing plate 32 to move up and down through the structure of the screw rod 44 and the slider 42.

[0034] Specifically, the frame 1 also includes a working window 13, and a control function area 14 is provided at the upper end of the working window 13. The control function area 14 includes a control panel 141 and a control button 142. The side of the working window 13 close to the first paper counting device 2 is also connected to a screen curtain 131, and one end of the screen curtain 131 is fixed to one side of the first paper counting device 2 and linked with it to cover and open the working window 13. A compression device 15 and a microcomputer device 16 are also provided on one side of the mounting frame 12. The operation panel 11 is provided with an air outlet 111, and the air outlet 111 is supplied with air by the compression device 15 through the air duct. The air outlet 111 can help the paper to be tested to reduce the friction during sliding by blowing air upwards, so as to facilitate the sliding of the paper to be tested. In addition, the screen curtain 131 preferably adopts a wave-type rolling shutter door design, and fixed slide rails 41 are set on the upper and lower sides of the working window 13, and pulley groups are set at the upper and lower ends of the screen curtain 131. As other alternatives, the screen curtain 131 can directly adopt a curtain design, and the screen curtain 131 can cover the components in the first paper counting device 2.

[0035] Specifically, as mentioned above, the first paper counting device 2 and the second paper counting device 3 adopt the existing structure paper counting device.
