Technical Field

[0001] The utility model relates to the technical field of cardboard cutting machines, and particularly relates to a feeding mechanism of a cardboard cutting machine. Background Technique

[0002] A packaging box is a cardboard box used for packaging products. During the production process of the cardboard box, a cardboard cutting machine is required to cut it. The cutting machine is used for the division and cutting of cardboard, without the need for any molds, but is controlled by a system software, and then the cardboard is automatically cut according to the size requirements.

[0003] At present, when most packaging paper boxes are produced, manual assistance is required to continuously transport and feed the cardboard. This method requires an increase in labor and reduces work efficiency, which is not conducive to the development of enterprises. Therefore, we provide a feeding mechanism for a cardboard cutting machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a feeding mechanism of a cardboard cutting machine to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

The cardboard cutting machine body includes a cutting table, and a feeding table is fixedly installed on the left side of the cutting table. Support legs are welded to the bottom ends of both the feeding table and the cutting table.

[0007] A feeding unit is arranged on the top of the feeding table, and a limiting unit is arranged on the left side of the top of the feeding unit.

[0008] The feeding unit of the utility model further includes a bearing plate at the bottom ends of the inner walls on both sides of the feeding table. A support plate is fixedly installed at the bottom end of the bearing plate, and the other end of the support plate is welded to the left side of the cutting table below the feeding table.

[0009] The utility model further improves the technical solution in that: sliding grooves are opened on the inner walls on both sides of the support plate. A supporting plate is fixedly installed at the left bottom end of the sliding groove. A supporting bracket is welded to the bottom end of the supporting plate, and a motor is fixedly installed inside the supporting bracket. The sliding groove can limit the sliding plate when it moves left and right to prevent displacement.

[0010] A further improvement of the technical solution of the present utility model lies in that: a driving rod is fixedly installed on the output end of the motor, a rotating plate is fixedly sleeved on the other end of the driving rod, a pulling strip plate is rotatably connected to the other end of the rotating plate, a sliding plate is rotatably connected to the other end of the pulling strip plate, and the sliding plate is slidably installed inside the chute.

[0011] A further improvement of the technical solution of the present utility model lies in that: a rotating shaft is fixedly installed on the top of the sliding plate, a pushing rod is rotatably installed at the inner center of the rotating shaft, and a counterweight rod is fixedly installed at the left bottom end of the pushing rod.

[0012] A further improvement of the technical solution of the present utility model lies in that: the limiting unit includes a mounting hole opened on the left top of the feeding table, and a limiting frame is detachably installed on the left top of the feeding table. The limiting frame can be quickly disassembled and assembled by pulling it up.

[0013] A further improvement of the technical solution of the present utility model lies in that: inserting rods are fixedly installed on the four peripheries of the bottom end of the limiting frame, and the inserting rods are movably inserted inside the mounting hole.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] 1. The present utility model provides a feeding mechanism for a cardboard cutting machine. By setting a motor to drive a driving rod, the rotating plate rotates uniformly. When the rotating plate rotates, it drives the pulling strip plate to cause the sliding plate to move left and right inside the chute. When the sliding plate moves to the left and the pushing rod touches the cardboard, the pushing rod will rotate downward and then come to the left side of the cardboard. At this time, under the action of the gravity of the counterweight rod, the pushing rod resets to the upright state. When the sliding plate moves to the right, the pushing rod cannot rotate downward under the resistance of the counterweight rod, and the cardboard at the bottom end inside the limiting frame can be pushed towards the cutting table, realizing automatic feeding and improving work efficiency.

[0016] 2. The present utility model provides a feeding mechanism for a cardboard cutting machine. By setting a limiting frame, the stacked cardboard can be neatly stacked together. The bottom of the limiting frame is parallel to the top of the pushing rod. Therefore, each time the cardboard is pushed, the same number of cardboard can be pushed, and the top cardboard will not tilt. When the bottom cardboard is pushed away, the top cardboard will automatically fall downward, facilitating the next feeding and improving the convenience and flexibility of use.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1-5 shown, the present utility model provides a loading mechanism for a cardboard cutting machine, including the main body 1 of the cardboard cutting machine. The main body 1 of the cardboard cutting machine includes a cutting table 2. A loading table 3 is fixedly installed on the left side of the cutting table 2. Support legs 4 are welded to the bottom ends of both the loading table 3 and the cutting table 2. A loading unit is arranged on the top of the loading table 3. A limit unit is arranged on the upper left side of the top of the loading unit. The limit unit includes a mounting hole 314 opened on the upper left side of the loading table 3. A limit frame 315 is detachably installed on the upper left side of the top of the loading table 3. Insertion rods 316 are fixedly installed around the bottom end of the limit frame 315. The insertion rods 316 are movably inserted into the inside of the mounting hole 314.

[0026] Furthermore, by setting the limit frame 315, the stacked cardboard can be neatly stacked together. The bottom of the limit frame 315 is parallel to the top of the pushing rod 312. Thus, each time the cardboard is pushed, the same number of cardboard can be pushed, and the top cardboard will not tilt. When the bottom cardboard is pushed away, the top cardboard will automatically fall down, facilitating the next loading.

[0027] Embodiment 2

[0028] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the feeding unit includes a bearing plate 31 at the bottom ends of the inner walls on both sides of the feeding table 3. A support plate 32 is fixedly installed at the bottom end of the bearing plate 31. The other end of the support plate 32 is welded to the left side of the cutting table 2 and is located below the feeding table 3. Chute 33 is provided on the inner walls on both sides of the support plate 32. A supporting plate 34 is fixedly installed on the left bottom end of the chute 33. A supporting bracket 35 is welded to the bottom end of the supporting plate 34. A motor 36 is fixedly installed inside the supporting bracket 35. A driving rod 37 is fixedly installed at the output end of the motor 36. A rotating plate 38 is fixedly sleeved at the other end of the driving rod 37. A pulling strip 39 is rotatably connected to the other end of the rotating plate 38. A sliding plate 310 is rotatably connected to the other end of the pulling strip 39. The sliding plate 310 is slidably installed inside the chute 33. A rotating shaft 311 is fixedly installed at the top of the sliding plate 310. A pushing rod 312 is rotatably installed at the inner center of the rotating shaft 311. A counterweight rod 313 is fixedly installed at the left bottom end of the pushing rod 312.

[0029] Furthermore, the output end of the motor 36 drives the driving rod 37 to make the rotating plate 38 rotate uniformly. When the rotating plate 38 rotates, it drives the pulling strip to cause the sliding plate 310 to move left and right inside the chute 33. When the sliding plate 310 moves to the left and the pushing rod 312 touches the cardboard, it will rotate downward, and then come to the left side of the cardboard. At this time, under the action of the gravity of the counterweight rod 313, the pushing rod 312 resets to the upright state. When the sliding plate 310 moves to the right, the pushing rod 312 cannot rotate downward under the resistance of the counterweight rod 313, and the cardboard at the bottom end inside the limiting frame 315 can be pushed towards the cutting table 2 to achieve automatic feeding.

[0030] Next, the working principle of the feeding mechanism of the cardboard cutting machine will be specifically described.

[0031] As Figures 1-5As shown in the figure, during use, the cardboard to be cut is placed on the left side of the feeding table 3 on top of the bearing plate 31. With the cooperation of the limiting frame 315, the stacked cardboard can be neatly stacked together. Then, the output end of the motor 36 drives the driving rod 37, causing the rotating plate 38 to rotate uniformly. When the rotating plate 38 rotates, it drives the pulling strip plate to cause the sliding plate 310 to move left and right inside the sliding groove 33. When the sliding plate 310 moves to the left, when the pushing rod 312 touches the cardboard, it will rotate downward and then come to the left side of the cardboard. At this time, under the gravity of the counterweight rod 313, the pushing rod 312 resets to the upright state. When the sliding plate 310 moves to the right, the pushing rod 312 cannot rotate downward under the resistance of the counterweight rod 313, and the cardboard at the bottom end inside the limiting frame 315 can be pushed towards the cutting table 2 to achieve automatic feeding. The bottom of the limiting frame 315 is parallel to the top of the pushing rod 312, so the same number of cardboard can be pushed each time during feeding.

[0032] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
