Description

Technical Field

[0001] This utility model relates to the field of paperboard processing technology, specifically to a paperboard feeding device for a carton printing machine. Background Technology

[0002] In the carton printing production process, the cardboard feeding device plays a crucial role. Traditional carton printing machines mostly rely on relatively simple and direct mechanical structures for the cardboard feeding process. Many small printing plants use basic conveyor belt feeding, which means that cardboard stacked at one end by hand is transported to the printing area one by one through a conveyor belt that rotates at a constant speed.

[0003] In existing technology, when cardboard gets stuck during the conveying process, the lack of an effective ejection component means that the stuck cardboard will directly block the normal conveying path of the following materials, which can easily cause material accumulation. The continuous flow of cardboard will continue to push forward under the action of inertia, making the accumulation more and more serious. However, the operating space inside the equipment is small, and the staff must use clamps to remove the cardboard, which is a cumbersome operation. Utility Model Content

[0004] The purpose of this invention is to provide a cardboard feeding device for a carton printing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cardboard feeding device for a carton printing machine, comprising:

[0006] Conveyor belt;

[0007] A pop-up component is placed inside a conveyor belt. The pop-up component includes a triangular frame slidably connected to the conveyor belt, a sliding block slidably connected inside the triangular frame, a sliding shaft fixedly connected to the sliding block, an inclined groove on the triangular frame, the sliding shaft slidably connected to the inclined groove on the triangular frame, a blocking block slidably connected to the triangular frame, a first spring piece slidably connected to the blocking block, and one end of the first spring piece away from the blocking block fixedly connected to the conveyor belt.

[0008] A first rotating shaft is rotatably connected to a conveyor belt. A first transmission rod is fixedly connected to the first rotating shaft. A second rotating shaft is rotatably connected to the first transmission rod. A second transmission rod is rotatably connected to the second rotating shaft. A transmission block is rotatably connected to the second rotating shaft. A third rotating shaft is rotatably connected to a sliding block. A sliding rod is fixedly connected to the transmission block.

[0009] Furthermore, a bracket is fixedly connected to the conveyor belt, a torsion spring is fixedly connected to the bracket on the conveyor belt, a connecting rod is fixedly connected to the torsion spring, a roller is rotatably connected to the connecting rod, and the roller on the connecting rod is slidably connected to the conveyor belt.

[0010] The above technical solution involves incorporating rollers. During use, the rollers apply downward pressure to the cardboard using the force of a torsion spring, reducing the possibility of displacement.

[0011] Furthermore, a rolling rod is rotatably connected to the conveyor belt.

[0012] The above technical solution employs a rolling rod that limits the movement of the cardboard during use.

[0013] Furthermore, the conveyor belt is provided with three supports. Among the three supports on the conveyor belt, a damping spring is fixedly connected to the support near the first rotating shaft. A second spring is fixedly connected to the bottom of the damping spring, and the side of the second spring near the support is fixedly connected to the support.

[0014] The above technical solution is adopted: when in use, the downward pressure of the second spring is used to further limit the cardboard and prevent it from shifting. When the cardboard leaves the roller, the second spring limits it.

[0015] Furthermore, a reset spring is fixedly connected to the bottom of the blocking block.

[0016] The above technical solution is adopted so that, during use, the reset spring supports the blocking block to prevent the support block from falling off directly.

[0017] Furthermore, a pressing block is fixedly connected to the sliding rod.

[0018] The above technical solution is adopted: during use, the sliding rod is limited by the pressure block.

[0019] Furthermore, the bottom of the reset spring is fixedly connected to the conveyor belt.

[0020] Using the above technical solution: prevent the return spring from falling off during use.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, when the cardboard gets stuck, the operator presses down the pressing block. The pressing block drives the fixedly connected sliding rod, which in turn causes the transmission block to press down. The transmission block, through the obliquely set second transmission rod, drives the sliding block to slide within the triangular frame. Due to the specific rotational and sliding connection between the triangular frame and the conveyor belt, the triangular frame slides away from the conveyor belt via the sliding shaft. This causes the blocking block to disengage from the triangular frame and move downward. The first spring then disengages from the blocking block and, under the action of elasticity, pushes inward, ejecting the cardboard between the second spring and the connecting rod. This creates ample operating space and avoids the problem of cardboard jamming and obstructing subsequent materials, causing material accumulation, which is common in traditional methods due to the lack of an effective ejection component. This greatly improves the smoothness of equipment operation, reduces downtime, and ensures production efficiency. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] like Figures 1-4 As shown, this utility model provides a technical solution: a cardboard feeding device for a carton printing machine, comprising:

[0035] Conveyor belt 1;

[0036] Pop-out component 2 is placed inside conveyor belt 1. Pop-out component 2 includes a triangular frame 22 slidably connected to conveyor belt 1. A sliding block 23 is slidably connected inside the triangular frame 22. A sliding shaft 21 is fixedly connected to the sliding block 23. An inclined groove is opened on the triangular frame 22. The sliding shaft 21 is slidably connected to the inclined groove on the triangular frame 22. A blocking block 25 is slidably connected to the triangular frame 22. A first spring piece 26 is slidably connected to the blocking block 25. One end of the first spring piece 26 away from the blocking block 25 is fixedly connected to the conveyor belt 1.

[0037] A first rotating shaft 3 is rotatably connected to a conveyor belt 1. A first transmission rod 31 is fixedly connected to the first rotating shaft 3. A second rotating shaft 33 is rotatably connected to the first transmission rod 31. A second transmission rod 32 is rotatably connected to the second rotating shaft 33. A transmission block 35 is rotatably connected to the second rotating shaft 33. A third rotating shaft 34 is rotatably connected to a sliding block 23. A sliding rod 36 is fixedly connected to the transmission block 35.

[0038] In this invention, when the cardboard gets stuck, the operator presses down the pressing block 37. The pressing block 37 drives the fixedly connected sliding rod 36, which in turn causes the transmission block 35 to press down. The transmission block 35, with the help of the obliquely set second transmission rod 32, drives the sliding block 23 to slide within the triangular frame 22. Since the triangular frame 22 and the conveyor belt 1 have a specific rotational and sliding connection, the triangular frame 22 slides away from the conveyor belt 1 via the sliding shaft 21. This causes the blocking block 25 to move down away from the limit of the triangular frame 22. The first spring 26 then moves away from the limit of the blocking block 25 and pushes inward under the action of elasticity, popping the cardboard between the second spring 43 and the connecting rod 41. This creates sufficient operating space and avoids the problem of cardboard getting stuck and hindering subsequent materials and causing material accumulation caused by the lack of an effective ejection component 2 in the traditional method. This greatly improves the smoothness of equipment operation, reduces the number of downtimes, and ensures production efficiency.

[0039] Furthermore, such as Figures 1 to 4 As shown, a bracket is fixedly connected to the conveyor belt 1, a torsion spring 4 is fixedly connected to the bracket on the conveyor belt 1, a connecting rod 41 is fixedly connected to the torsion spring 4, a roller is rotatably connected to the connecting rod 41, and the roller on the connecting rod 41 is slidably connected to the conveyor belt 1. By setting the roller, when in use, the roller uses the force of the torsion spring 4 to apply downward pressure to the cardboard, reducing the possibility of its displacement.

[0040] A rolling rod is rotatably connected to the conveyor belt 1. The rolling rod serves to limit the transmission of the cardboard during use.

[0041] There are three supports on the conveyor belt 1. Among the three supports on the conveyor belt 1, the support closest to the first rotating shaft 3 is fixedly connected to a damping spring 42. The bottom of the damping spring 42 is fixedly connected to a second spring plate 43. The side of the second spring plate 43 closest to the support is fixedly connected to the support. When in use, the downward pressure of the second spring plate 43 is used to further limit the cardboard and prevent it from shifting. When the cardboard leaves the roller, the second spring plate 43 limits it.

[0042] A return spring 24 is fixedly connected to the bottom of the blocking block 25. When in use, the return spring 24 supports the blocking block 25 to prevent the support block from falling off directly.

[0043] A pressing block 37 is fixedly connected to the sliding rod 36. During use, the pressing block 37 limits the sliding rod 36.

[0044] The above solution also has the problem of not specifying the fixed position of the return spring 24, such as... Figure 2 as well as Figure 4 As shown, the bottom of the reset spring 24 is fixedly connected to the conveyor belt 1 to prevent the reset spring 24 from falling off during use.

[0045] Working principle: such as Figures 1-4 As shown;

[0046] Before use, place the printing press on the end of the conveyor belt 1 away from the torsion spring 4, start the conveyor belt 1, and make the conveyor belt 1 move the cardboard.

[0047] Subsequently, when the cardboard is displaced during transmission, the worker directly presses down the pressing block 37, causing the sliding rod 36 to drive the transmission block 35 to press down. This causes the obliquely set second transmission rod 32 to drive the sliding block 23 to slide within the triangular frame 22. The triangular frame 22 is then driven by the sliding shaft 21 to slide away from the conveyor belt 1, causing the blocking block 25 to disengage from the limit of the triangular frame 22. As the blocking block 25 moves down, the first spring 26 disengages from the limit of the blocking block 25 and moves inward. The first springs 26 on both sides move inward simultaneously, popping the cardboard between the second spring 43 and the connecting rod 41. This allows the worker sufficient operating space to remove the cardboard, preventing it from getting stuck and making it inconvenient for the worker to remove.

[0048] After removing the stuck cardboard, slide the sliding block 23 in the opposite direction, causing the sliding block 23 to drive the triangular frame 22 to slide closer to the conveyor belt 1. This causes the triangular frame 22 to push the blocking block 25 upward. The blocking block 25 is subjected to the squeezing force of the triangular frame 22 on one side and abuts against the inside of the conveyor belt 1 on the other side, thus realizing the upward transmission of the blocking block 25.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
