Description

Technical Field

[0001] The utility model relates to the technical field of counting equipment, in particular to a cardboard production counting equipment. Background Art

[0002] In the production and processing process of cardboard, it is necessary to count or count the produced cardboard and then pack and transport it to meet the order requirements of customers. However, the number of customers' orders is usually huge, and manual counting is inefficient and labor-intensive.

[0003] In order to improve the efficiency of counting cardboard, many improvements have been made to the cardboard production counting equipment in the prior art. For example, the patent with the patent announcement number CN210312831U discloses a cardboard stacking machine with an accurate counting function, including a frame; a first conveying device connected to the upper direction of the frame for conveying cardboard into the frame; a second conveying device arranged below the frame for receiving the cardboard falling from the frame; two supporting plates are relatively arranged in the frame, and the supporting plates are connected to the frame through spring hinges. A first hydraulic cylinder is longitudinally arranged above the frame, and a first pushing plate is arranged on the telescopic rod of the first hydraulic cylinder; a counting device is arranged on one side of the frame opposite to the first conveying device, and the counting device is electrically connected to the first hydraulic cylinder to control its start and stop. Through the above structure, the automatic stacking of cardboard during transportation can be realized, and the accurate counting of cardboard can be realized through the counting device, and finally the purpose of reducing the labor intensity of workers and improving the production efficiency can be achieved.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figures 1 - 9A cardboard production counting device comprises a first conveying device 1 and a second conveying device 2 at two different heights, both used to convey cardboards. A fixed frame 3 is provided between the first conveying device 1 and the second conveying device 2, and a movable carrying plate 4 is provided in the fixed frame 3. A first driving unit 5 for driving the movable carrying plate 4 to move downward intermittently is provided on the upper part of the fixed frame 3. A vertical baffle 6 is provided on the side of the fixed frame 3 close to the second conveying device 2, and a counting device 7 adapted to the height of the first conveying device 1 is fixedly mounted on the baffle 6. A second driving unit 8 for driving the baffle 6 to move is provided on one side of the fixed frame 3, and a third driving unit 9 for transferring the cardboard stack to the second conveying device 2 is provided on the movable carrying plate 4. A fourth driving unit 10 for assisting the movement of the cardboard is provided on the side of the fixed frame 3 close to the first conveying device 1.

[0032] Specifically, the above-mentioned first conveying device 1 is used to convey individual cardboards, and the second conveying device 2 is used to convey stacked cardboard stacks. The height of the first conveying device 1 is higher than that of the second conveying device 2. The first driving unit 5 drives the movable carrier plate 4 to a position adapted to the first conveying device 1. The cardboard is conveyed to the upper surface of the movable carrier plate 4 by the first conveying device 1, and the cardboard is assisted to move on the movable carrier plate 4 by the fourth driving unit 10. One side of the cardboard contacts one side of the baffle 6, and one side of the cardboard contacts the counting device 7. The counting device 7 transmits data to the external main controller and displays it through the display interface. The counting device 7 can be a contact type structure. When the counting device 7 finishes counting, the first driving unit 5 is started, which drives the movable carrier plate 4 to move down to the thickness of one cardboard. The cardboard on a conveying device 1 moves again to the top of the cardboard below and contacts the counting device 7 again for counting. When the movable carrier plate 4 moves to the bottom of the fixed frame 3, the first conveying device 1 is stopped and the second driving unit 8 is turned on. The second driving unit 8 drives the baffle 6 to move. After the baffle 6 moves, it does not hinder the transfer of the cardboard stack to the second conveying device 2. At this time, the third driving unit 9 is started. The third driving unit 9 transfers the cardboard stack on the movable carrier plate 4 to the second conveying device 2, completing the palletizing and counting of the cardboard stack. After the cardboard stack is transferred through the second conveying device 2, the second driving unit 8 drives the baffle 6 to its original position again, and drives the movable carrier plate 4 to rise again through the first driving unit 5, and continues to palletize and count the cardboard, thereby improving the effect and efficiency of counting the cardboard.

[0033] As a technical optimization solution of the present utility model, the first driving unit 5 includes a first driving motor 11 fixedly installed on the upper part of the fixing frame 3. A plurality of side surfaces of the moving bearing plate 4 are fixedly connected with first sliding blocks 12. A plurality of side walls in the fixing frame 3 are provided with first sliding grooves 13 adapted to the first sliding blocks 12. A first lead screw 14 extending to the upper part of the fixing frame 3 is rotatably connected in the first sliding groove 13. The first lead screw 14 penetrates through the first sliding block 12 and is threadedly connected with the first sliding block 12. First transmission wheels 15 are fixedly installed on the side surfaces of the upper end of the first lead screw 14 and the output end of the first driving motor 11. A first transmission belt 16 for transmission is sleeved between the side surfaces of several first transmission wheels 15. A tensioning unit 17 for tensioning the first transmission belt 16 is provided on the upper part of the fixing frame 3.

[0034] Specifically, when it is necessary to adjust the position of the moving bearing plate 4, start the first driving motor 11. The output end of the first driving motor 11 drives the first transmission wheel 15 on its side surface to rotate. This first transmission wheel 15 drives other first transmission wheels 15 to rotate through the first transmission belt 16. The first transmission wheel 15 drives the first lead screw 14 to rotate. When the first lead screw 14 rotates, it drives the first sliding block 12 to slide in the first sliding groove 13. The first sliding block 12 drives the moving bearing plate 4 to move. Among them, the first driving motor 11 is a programmable and self-locking motor, and the moving distance of the moving bearing plate 4 driven each time can be controlled according to the thickness of the cardboard.

[0035] As a technical optimization solution of the present utility model, the second driving unit 8 includes a second driving motor 18 fixedly installed on the side surface of the fixing frame 3. Second sliding blocks 19 are fixedly installed on both side surfaces of the baffle 6. Two symmetric second sliding grooves 20 adapted to the second sliding blocks 19 are provided on one side of the fixing frame 3. A second lead screw 21 extending to the outside is rotatably connected in the second sliding groove 20. The second lead screw 21 penetrates through the second sliding block 19 and is threadedly connected with the second sliding block 19. A second transmission wheel 22 is fixedly installed on the side surface of the end of the second lead screw 21 located outside. A second transmission belt 23 for transmission is sleeved between the side surfaces of the two second transmission wheels 22. The output end of the second driving motor 18 is fixedly connected to the end of one second lead screw 21.

[0036] Specifically, when it is necessary to move the position of the baffle 6, start the second driving motor 18. The output end of the second driving motor 18 drives one of the second transmission wheels 22 to rotate. This second transmission wheel 22 drives the other second transmission wheel 22 to rotate through the second transmission belt 23. When the second transmission wheel 22 rotates, it drives the second lead screw 21 to rotate. When the second lead screw 21 rotates, it drives the second sliding block 19 to slide in the second sliding groove 20. The second sliding block 19 drives the baffle 6 to move along the second sliding groove 20 to move the position of the baffle 6.

[0037] As a technical optimization solution of the utility model, the third driving unit 9 includes a third driving motor 24 fixedly installed on one side of the moving carrier plate 4. A plurality of rotating grooves 25 are formed on the upper side of the moving carrier plate 4. A driving roller 26 is rotatably connected in the rotating groove 25. One end of a plurality of driving rollers 26 extends to the outside and a third transmission wheel 27 is fixedly installed on the side surface. The output end of the third driving motor 24 is fixedly connected to one third transmission wheel 27. A third transmission belt 28 for transmission is sleeved between the side surfaces of two adjacent third transmission wheels 27.

[0038] Specifically, when it is necessary to transfer the stacked cardboard stack to the second conveying device 2, the third driving motor 24 is started. The output end of the third driving motor 24 drives one of the third transmission wheels 27 to rotate. The third transmission wheel 27 drives other third transmission wheels 27 to rotate through the third transmission belt 28. The third transmission wheel 27 drives the driving roller 26 to rotate in the rotating groove 25. The driving roller 26 drives the cardboard stack to move onto the second conveying device 2. The upper side surface of the driving roller 26 exceeds the upper surface of the moving carrier plate 4.

[0039] As a technical optimization solution of the utility model, the fourth driving unit 10 includes a rotating roller 30 rotatably connected between the opposite side walls in the fixed frame 3. A fourth driving motor 29 for driving the rotating roller 30 to rotate is fixedly installed on the side surface of the fixed frame 3.

[0040] Specifically, when the fourth driving motor 29 is turned on, the output end of the fourth driving motor 29 drives the rotating roller 30 to rotate. When one side of the cardboard contacts the rotating roller 30 during the conveying of the cardboard by the first conveying device 1, the rotating roller 30 also starts to convey the cardboard, driving the cardboard to move on the moving carrier plate 4 to prevent one side of the cardboard from not touching the baffle 6.

[0041] As a technical optimization solution of the utility model, the tensioning unit 17 includes a fixed seat 31 fixedly installed on the upper part of the fixed frame 3. There are two symmetrical moving frames 32 located at both ends of the fixed seat 31 on the upper part of the fixed frame 3. A tensioning wheel 33 adapted to the first transmission belt 16 is rotatably connected in the moving frame 32. One side of the moving frame 32 is fixedly connected to a guide post 34 with one end inserted into the fixed seat 31. A spring 35 sleeved on the side surface of the guide post 34 is arranged between the fixed seat 31 and the fixed frame 3. A limiting groove 36 adapted to the moving frame 32 is formed on the upper part of the fixed frame 3.

[0042] Specifically, the spring 35 always exerts a tension on the moving frame 32, so that the tensioning wheel 33 tensions the first transmission belt 16, ensuring the synchronism of the transmission of the first transmission belt 16 to a plurality of first transmission wheels 15. The limiting groove 36 and the guide post 34 with one end inserted into the fixed seat 31 play a limiting role on the moving frame 32, and at the same time facilitate the replacement and installation of the first transmission belt 16 in the later stage.

[0043] As a technical optimization solution of the present invention, two symmetrical limiting plates 37 that pass through the upper part of the fixed frame 3 are fixedly installed on the upper side of the movable carrier plate 4. The limiting plates 37 limit the sides of the cardboard to prevent displacement when the cardboard is stacked.
