Description

Technical Field

[0001] The utility model relates to the field of carton production, in particular to a feeding mechanism for high-toughness carton printing production. Background Technique

[0002] In the process of carton production, corrugated paper is generally cut into cardboard of corresponding sizes first, and then the cardboard is printed, scored, and grooved. Finally, it is folded into a carton. When printing the cardboard, the stacked cartons are generally placed on a feeding mechanism and conveyed into a printing machine for printing.

[0003] In a Chinese utility model patent with the publication number CN212639280U, an automatic feeding mechanism for cardboard printing is disclosed, including a feeding pipe and a pushing plate mechanism. The pushing plate mechanism includes a pushing block that can reciprocate in the left-right direction. It can automatically convey the cardboard to the printing machine for printing, effectively improving the printing efficiency of the cardboard and reducing the labor intensity of workers. In the above structure, multiple straight boxes are stacked together, and the pushing plate mechanism is used to push out and convey the lowermost straight box. When multiple cartons are stacked together, the cartons stacked on the upper part will exert a large pressure on the cardboard at the bottom, which requires strong pushing. Strong pushing will damage the edges of the cardboard and affect its use. Therefore, we have designed a feeding mechanism for high-toughness carton printing production. Content of the Utility Model

[0004] To solve the technical problem that when multiple cartons are stacked together, the cartons stacked on the upper part will exert a large pressure on the cardboard at the bottom, resulting in difficult pushing, the utility model provides a feeding mechanism for high-toughness carton printing production.

[0005] The utility model is realized by adopting the following technical solutions: A feeding mechanism for high-toughness carton printing production includes two symmetrically arranged frames in the front and back. Between the two frames, a plurality of equally spaced conveying rollers are rotatably installed through bearings, and a pushing mechanism is arranged at the left end between the two frames. The pushing mechanism includes two longitudinally installed mounting plates. Between the two mounting plates, a moving screw is rotatably installed through a bearing. The left end of the moving screw is connected to a driving motor through a coupling. A moving nut is installed on the moving screw. An outer sleeve of the moving nut is provided with a moving plate. On the left side surface of the moving plate, a plurality of equally spaced pushing plates are arranged;

[0006] A scissor lift is also arranged on the left side between the two frames, and a loading plate is arranged at the top of the scissor lift.

[0007] As a further improvement of the above scheme, sprockets are installed at the rear ends of the multiple conveying rollers, and the multiple conveying rollers are connected by sprockets and chains. A conveying motor is installed under the rear frame, and the conveying roller on the left is connected to the output shaft of the conveying motor through a chain. A sprocket is installed on the output shaft of the conveying motor. The conveying motor can rotate the multiple conveying rollers, and then the cartons on the conveying rollers can move to the right for feeding.

[0008] As a further improvement to the above solution, the two frames are each provided with a side baffle on the inner side, and a limit baffle is provided between the two side baffles. The two side baffles and the inner side of the limit baffle are in sliding contact with the outer surface of the unloading plate. The side baffles on the front and rear sides can limit the front and rear ends of the carton to keep it level and prevent position deviation.

[0009] The limiting baffle is located at the left end of the leftmost conveyor roller, and the top of the limiting baffle is flush with the outer ring surface of the conveyor roller. The limiting baffle at the right end can limit the right end of the carton, and when the top carton is loaded to the right, the remaining cartons will not move with it.

[0010] As a further improvement of the above scheme, when the top of the scissor lift rises to the maximum stroke, the upper end surface of the discharge plate is flush with the outer ring surface of the conveyor roller. The scissor lift is a screw lift that ensures the accuracy of each lift, and the height of the discharge plate rising each time is the thickness of a carton, so that the bottom end of the top carton is flush with the upper surface of the conveyor roller and the top of the limit baffle, and the cartons below will be blocked by the limit baffle and cannot move to feed.

[0011] As a further improvement of the above-mentioned solution, two guide rods are symmetrically arranged between the two mounting plates about the movable screw, and the front and rear ends of the movable plate are slidably sleeved on the guide rods. The movable plate can move to the left to the outside of the left side of the discharge plate, so that the push plate is on the left side of the carton above the discharge plate, and then can push the carton to the right to move to the conveyor roller for loading.

[0012] As a further improvement of the above scheme, a plurality of equally spaced screws are provided on the left side of the movable plate, and a strip hole is opened on the push plate. The push plate is sleeved on the screw through the strip hole, and a nut is threadedly connected to the screw, and the nut is pressed on the surface of the push plate, so that the push plate can be quickly installed and disassembled, and the height between the push plate and the top of the discharge plate can be changed, so that the lower end of the push plate can be below the upper surface of the top straight line and will not contact the second to last carton, thereby facilitating the movement and loading of the top carton.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a scissor lift at the left end of the frame, and the feeding plate is arranged on the top of the scissor lift. Multiple stacked cartons are placed above the feeding plate. With the cooperation of the moving plate and the pushing plate that move left and right, the top carton of the multiple stacked cartons can be fed, and it will not be squeezed, which is convenient for feeding.

[0015] 2. By arranging a limited baffle on the right side of the feeding plate, it can limit the right end of the carton, so that when the top carton is fed diagonally upward to the right, the other cartons will not move along with it, and it ensures that only one carton is conveyed each time, so that the cartons will not be stacked on the conveying rollers, which is convenient for subsequent printing.

[0022] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0023] Embodiment:

[0024] Please combine with Figures 1 - 4, A feeding mechanism for high-toughness carton printing production in this embodiment includes two symmetrically arranged front and rear frames 1. Between the two frames 1, a plurality of equally spaced conveying rollers 2 are rotatably installed through bearings. And at the left end between the two frames 1, a pusher mechanism 3 is provided. Among them, the pusher mechanism 3 includes two longitudinally installed mounting plates 31. Between the two mounting plates 31, a moving screw 35 is rotatably installed through a bearing. The left end of the moving screw 35 is connected to a driving motor 36 through a coupling. A moving nut is installed on the moving screw 35. An outer sleeve of the moving nut is provided with a moving plate 33. On the left side surface of the moving plate 33, a plurality of equally spaced pusher plates 34 are provided;

[0025] On the left side between the two frames 1, a scissor lift 4 is further provided. The top of the scissor lift 4 is provided with a loading plate 5.

[0026] Sprockets are installed at the rear ends of the plurality of conveying rollers 2. And between the plurality of conveying rollers 2, they are connected through sprockets and chains. A conveying motor 21 is installed below the rear frame 1. The left conveying roller 2 is connected to the output shaft of the conveying motor 21 through a chain. A sprocket is installed on the output shaft of the conveying motor 21. The conveying motor 21 can make the plurality of conveying rollers 2 rotate. Thus, it can make the cartons on the conveying rollers 2 move rightward for feeding.

[0027] On the inner sides of the two frames 1, side baffles 6 are provided. Between the two side baffles 6, a limiting baffle 7 is provided. The inner sides of the two side baffles 6 and the limiting baffle 7 are all in sliding contact with the outer surface of the loading plate 5. The front and rear side baffles 6 can limit the front and rear ends of the carton, making it remain horizontal without position deviation;

[0028] The limiting baffle 7 is at the left end of the leftmost conveying roller 2. The top of the limiting baffle 7 is flush with the upper surface of the outer ring of the conveying roller 2. The right limiting baffle 7 can limit the right end of the carton. And when the uppermost carton is fed upward to the right, the remaining cartons will not move along with it.

[0029] When the top of the scissor lift 4 rises to the maximum stroke, the upper surface of the loading plate 5 is flush with the upper surface of the outer ring of the conveying roller 2. The scissor lift 4 is a screw lift table, which ensures the accuracy during each lift. And the height that the loading plate 5 rises each time is the spacing of the thickness of one carton. Thus, the bottom end of the uppermost carton is flush with the upper surface of the conveying roller 2 and the top of the limiting baffle 7. And the lower cartons will be blocked by the limiting baffle 7 and cannot move for feeding.

[0030] There are two guide rods 32 symmetrically arranged between two mounting plates 31 with respect to the moving screw rod 35. The front and rear ends of the moving plate 33 are slidably sleeved on the guide rods 32. The moving plate 33 can move leftward to the outside of the left side of the feeding plate 5, so that the pushing plate 34 is located on the left side of the cardboard box above the feeding plate 5. Thus, it can push the cardboard box to move rightward onto the conveying rollers 2 for feeding.

[0031] A plurality of screws are arranged at equal intervals on the left side edge of the moving plate 33. A strip-shaped hole is formed on the pushing plate 34. The pushing plate 34 is sleeved on the screws through the strip-shaped hole. And a nut is threadedly connected to the screw, and the nut is pressed on the surface of the pushing plate 34, which can quickly install and disassemble the pushing plate 34, and can change the height between the bottom end of the pushing plate 34 and the top of the feeding plate 5, so that the lower end of the pushing plate 34 can be placed below the upper surface of the uppermost cardboard box and will not contact the second-to-last cardboard box. Thus, it is convenient for the uppermost cardboard box to move and be fed.

[0032] The implementation principle of a feeding mechanism for high-toughness cardboard box printing production in the embodiment of the present application is as follows: In actual use, first, the feeding plate 5 is lowered to the lowest position under the action of the scissor lift 4. At this time, a plurality of stacked cardboard boxes can be palletized and placed above the feeding plate 5 (the upper surface height of the uppermost cardboard box on the feeding plate 5 is flush with the top of the limit baffle 7. At this time, the bottom end of the pushing plate 34 is above the upper surface of the uppermost cardboard box). Connecting the power supply of the conveying motor 21 can make the plurality of conveying rollers 2 rotate synchronously, and connecting the power supply of the driving motor 36 and making the moving plate 33 be located on the outside left side of the feeding plate 5. When feeding, the feeding plate 5 is lifted by the scissor lift 4 by the height of the thickness of one cardboard box. At this time, the lower surface of the cardboard box and the bottom end of the uppermost cardboard box are flush with the upper surface of the conveying rollers 2 and the top of the limit baffle 7. The bottom end of the pushing plate 34 is below the upper surface of the uppermost cardboard box and will not contact the second-to-last cardboard box. The moving plate 33 and the pushing plate 34 move rightward and make the uppermost cardboard box move rightward above the conveying rollers 2. Thus, the cardboard box is fed to the right, and the lower cardboard boxes will be blocked by the limit baffle 7 and cannot move for feeding. Then the moving plate 33 and the pushing plate 34 move leftward again and are located on the outside left side of the feeding plate 5. The feeding plate 5 is lifted by the height of the thickness of one cardboard box again. Repeating the above operations can continuously feed the cardboard box to the right;

[0033] By arranging a scissor lift 4 at the left end of the frame 1, and the feeding plate 5 is arranged on the top of the scissor lift 4, and a plurality of palletized stacked cardboard boxes are placed above the feeding plate 5, and cooperating with the moving plate 33 and the pushing plate 34 that move left and right, the uppermost cardboard box of the plurality of stacked cardboard boxes can be fed, and it will not be squeezed, which is convenient for feeding;

[0034] By arranging a limited baffle 7 on the right side of the feeding plate 5, it can limit the right end of the carton, so that when the uppermost carton is fed towards the upper right, the other cartons will not move along with it, and it is ensured that only one carton is conveyed each time, so that the cartons will not stack on the conveying roller 2, which is convenient for subsequent printing.

[0035] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
