Description

Technical Field

[0001] This application relates to the technical field of corrugated cardboard processing, and particularly relates to a corrugated cardboard punching device. Background Art

[0002] Corrugated paper, also known as kraft paper, is a common material used for paper packaging boxes. It is lighter than wooden boxes and has hardness, and is easy to cut in size. It is used to protect other products being packaged from damage. Usually, before corrugated paper is used for packaging, it is processed to be bonded with box board to make corrugated cardboard. Corrugated cardboard has high hardness and is not easily scratched, so the market demand is large. And corrugated cardboard also needs to go through multiple processes during processing, and one of them is to punch holes in the corrugated paper. Therefore, a punching device is needed to punch holes in the corrugated cardboard.

[0003] In order to ensure that the corrugated paper can be smoothly punched, currently, generally, an avoidance groove is opened on the base of the punching device to facilitate the punch of the punching device to smoothly penetrate through the corrugated cardboard. Some corrugated cardboard needs to have multiple holes penetrated. Therefore, the existing avoidance groove is constructed in a strip shape to facilitate sequential punching of multiple holes located on a straight line. However, this strip-shaped avoidance groove makes the corrugated cardboard only have support points on both sides of the holes. Due to the large stress generated by the punch during stamping, this makes the support force around the holes to be punched on the corrugated cardboard uneven, and it is easy to cause deformation of the corrugated cardboard under the stamping stress, resulting in inability to smoothly punch holes and poor punching quality. Therefore, this application proposes a corrugated cardboard punching device. Summary of the Invention

[0004] The purpose of this application is to provide a corrugated cardboard punching device to solve the problem that the existing punching device has uneven support force around the holes to be punched on the corrugated cardboard, resulting in poor punching quality of the corrugated cardboard.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0028] As Figures 1-6 shown, a corrugated cardboard punching device proposed in an embodiment of the present application includes:

[0029] Base 1, on which a groove 2 is provided. The groove 2 can be used as an avoidance groove or a chip storage groove for storing waste paper scraps from stamping.

[0030] Punching mechanism 3, including a mounting frame 301 provided on the base 1. The mounting frame 301 is located directly above the groove 2. A first lead screw 302 and a first slide bar 303 are provided on the mounting frame 301. A moving plate 304 is movably arranged on the first lead screw 302 and the first slide bar 303. Preferably, the mounting frame 301 is configured as a gantry frame. The first lead screw 302 rotatably penetrates through the opposite inner walls of the mounting frame 301. The first slide bar 303 is fixedly connected to the opposite inner walls of the mounting frame 301. One end of the moving plate 304 is threadedly sleeved on the first lead screw 302, and the other end is slidably sleeved on the first slide bar 303. An electric push rod 305 is provided on the moving plate 304. A punch head 306 is provided at the piston end of the electric push rod 305. One end of the first lead screw 302 is connected to a first motor 307 provided on the mounting frame 301. When the first motor 307 operates, its output shaft drives the first lead screw 302 to rotate. Under the action of the thread, the moving plate 304 can be driven to slide horizontally along the first slide bar 303. When the electric push rod 305 operates, its piston end expands or contracts, which can drive the punch head 306 to move up and down. Cooperating with the sliding of the moving plate 304, punching operations can be performed on multiple hole positions of the corrugated cardboard.

[0031] Support mechanism 4, including a second lead screw 401 and a second slide bar 402 provided on the opposite inner walls of the groove 2. A ring plate 403 is movably arranged on the second lead screw 401 and the second slide bar 402. Preferably, the second lead screw 401 rotatably penetrates through the opposite inner walls of the groove 2. The second slide bar 402 is fixedly connected to the opposite inner walls of the groove 2. Two convex blocks are symmetrically configured on the ring plate 403. One of the convex blocks is threadedly sleeved on the second lead screw 401, and the other convex block is slidably sleeved on the second slide bar 402. The ring plate 403 is coaxially aligned with the punch head 306. A first pulley assembly 404 is connected between the second lead screw 401 and the first lead screw 302. When the first lead screw 302 rotates, the first pulley assembly 404 drives the second lead screw 401 to rotate synchronously. Under the action of the thread, the ring plate 403 slides horizontally along the second slide bar 402, so that no matter how the punch head 306 moves, the ring plate 403 always maintains a coaxial state with the punch head 306. During stamping, the corrugated cardboard is placed on the base 1, and the ring plate 403 supports the bottom of the corrugated cardboard. When the punch head 306 moves down to stamp the corrugated cardboard, supported by the ring plate 403, there are support points on the periphery of the hole positions to be stamped on the corrugated cardboard, making the support of the corrugated cardboard uniform, so as to facilitate the punch head 306 to perform stable punching, resulting in good punching quality.

[0032] The transmission mechanism 5 is arranged on the base 1 and is used for clamping and transporting corrugated paper. By arranging the transmission mechanism 5, the corrugated cardboard can be clamped and transported. Cooperating with the movement of the moving plate 304, the corrugated cardboard can be punched at multiple positions in sequence.

[0033] By opening a groove 2 on the base 1 and slidingly arranging an annular plate 403 in the groove 2, the annular plate 403 supports the position of the corrugated cardboard to be punched, so that there are support points on the periphery of the punching positions on the corrugated cardboard, making the support for the corrugated cardboard uniform and ensuring the punching quality. At the same time, the annular plate 403 moves synchronously with the punching head 306 to ensure effective support for any hole position on the corrugated cardboard, thus improving the practicability.

[0034] As Figure 5 and Figure 6 As shown, in some embodiments, the punching head 306 includes a punching column 3061 arranged at the piston end of the electric push rod 305. An annular cutting piece 3062 is arranged at the bottom end of the punching column 3061. By constructing the annular cutting piece 3062, the end face contact punching is changed to annular cutting punching. During punching, the annular cutting piece 3062 cuts the corrugated cardboard, not only making the punching smooth but also improving the punching quality. A circumferential cutting groove 6 is opened on the annular plate 403 and is in plug-in fit with the annular cutting piece 3062. Through the opened circumferential cutting groove 6, during punching, after the annular cutting piece 3062 punches through the corrugated cardboard, it is inserted into the circumferential cutting groove 6, so that there are circumferential support points on both the inner and outer sides of the punching position, further improving the punching quality. An air spraying part 7 is arranged on the punching column 3061, and the air spraying part 7 is used to spray out the corrugated paper slices clamped in the annular cutting piece 3062. Since some waste circular slices after punching are clamped in the annular cutting piece 3062 after the annular cutting piece 3062 punches the corrugated cardboard, through the arranged air spraying part 7, the waste is blown by the air flow, so as to wash the waste away from the annular cutting piece 3062, which not only facilitates the discharge of the waste but also is conducive to continuous punching, thus improving the practicability.

[0035] As Figure 6As shown, in some embodiments, the air spraying member 7 includes an air channel 701 opened at the bottom of the punching column 3061, and a sleeve 702 connected to the air channel 701 is provided on one side of the punching column 3061. An inner rod 703 is movably inserted in the sleeve 702. Preferably, the sleeve 702 is constructed in an inverted L shape, and the inner rod 703 is movably inserted in the vertical end of the sleeve 702. The bottom end of the inner rod 703 is lower than the ring slice 3062. When punching and punching, as the punching column 3061 is pressed, the inner rod 703 is moved downward. 1 moves downward, the inner rod 703 first contacts the corrugated cardboard, and under the action of the resistance force, the inner rod 703 gradually slides upward along the sleeve 702. As the ring slice 3062 contacts the corrugated cardboard, the inner rod 703 gradually moves upward, thereby squeezing the air in the sleeve 702 into the airway 701, and squeezing the air in the airway 701, so that the gas in the airway 701 is discharged outward, thereby using the airflow to blow out the waste chips stuck in the ring slice 3062.

[0036] like Figure 6 As shown, in some embodiments, the number of sleeves 702 and inner rods 703 are both two, and the free ends of the two inner rods 703 are connected with pressure rings 8. Through the provided pressure rings 8, the resistance force of the inner rods 703 is changed from a point to an annular surface, thereby increasing the contact area, preventing the inner rods 703 from penetrating the corrugated cardboard due to stress, and further ensuring the effect of blowing the waste chips by using airflow.

[0037] like Figure 6 As shown, in some embodiments, a piston plate 9 is slidably arranged in the air channel 701, and a resistance rod 10 is constructed at the bottom end of the piston plate 9. The bottom end of the air channel 701 is constructed with a closing end, and a spring 11 is connected between the closing end and the piston plate 9. When the ring slice 3062 is not in contact with the corrugated cardboard, the piston plate 9 drives the resistance rod 10 to move upward under the elastic force of the spring 11, so that the bottom end of the resistance rod 10 is higher than the bottom end of the ring slice 3062. When punching, the air in the sleeve 702 is squeezed and flows into the air channel 701, and the airflow will squeeze the piston plate 9 downward, so that the resistance rod 10 resists the waste chips, making it easier for the waste chips to fall off the ring slice 3062. When the punching is completed, after the punching column 3061 moves upward, the resistance rod 10 and the piston plate 9 are automatically reset under the elastic force of the spring 11, which is convenient for punching the next hole.

[0038] like Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, the transmission mechanism 5 includes two first transmission rollers 501, two through slots 502 are provided on the top of the base 1 and are both connected to the groove 2, the two first transmission rollers 501 rotate and penetrate the two through slots 502 respectively, two second transmission rollers 503 are rotatably provided on the mounting frame 301, the two second transmission rollers 503 correspond to the two first transmission rollers 501 respectively, the two first transmission rollers 501 are respectively located on both sides of the groove 2, one end of one of the first transmission rollers 501 is connected to a second motor 504 provided on the base 1, a second pulley assembly 505 is connected between the two first transmission rollers 501, gears 506 are fixedly provided on the first transmission roller 501 and the second transmission roller 503, and the two gears 506 are meshed with teeth, and when the corrugated cardboard is punched and punched, When punching a hole, place the corrugated cardboard on the base 1, and then move the corrugated cardboard horizontally so that the corrugated cardboard is moved and placed between the corresponding first transmission roller 501 and the second transmission roller 503. The first transmission roller 501 and the second transmission roller 503 clamp and resist the corrugated cardboard. The second motor 504 works, and its output shaft drives one of the first transmission rollers 501 to rotate. Through the linkage of the second pulley assembly 505, the other first transmission roller 501 is driven to rotate synchronously in the same direction. Under the linkage of the gear 506, the second transmission roller 503 is driven to rotate synchronously in the opposite direction to play the role of transmitting the corrugated cardboard. At the same time, the cooperation of the two first transmission rollers 501 and the two second transmission rollers 503 ensures that both ends of the corrugated cardboard at the punching position have pulling points, further improving the quality of punching.

[0039] like Figure 5 As shown, in some embodiments, a rubber sleeve 12 is fixedly provided on the first transmission roller 501 and the second transmission roller 503, and a plurality of convex strips 13 distributed in a ring shape are arranged in an array on the rubber sleeve 12. The rubber sleeve 12 and the convex strips 13 are arranged to increase the contact friction between the first transmission roller 501 and the second transmission roller 503 and the corrugated cardboard, which not only improves the clamping force on the corrugated cardboard, but also improves the stability of transmission.

[0040] like Figure 4 As shown, in some embodiments, a collection frame 14 located in the groove 2 is slidably inserted on one side of the base 1. Through the sliding and pulling of the collection frame 14, the waste chips generated by stamping fall into the collection frame 14. The collection frame 14 receives and collects the waste chips, which is convenient for cleaning the waste chips, thereby improving practicality.
