Description

Technical Field

[0001] The utility model relates to the technical field of paper shell perforation, in particular to a paper shell perforation device for preventing deviation. Background Art

[0002] The paper shell box is made of paper. Through certain technical means, the paper is stacked, folded and fixed in different ways to make a three-dimensional paper shell box from a flat paper shell, which is widely used in the logistics industry to facilitate the packaging and transportation of items. During the production process of the paper shell box, it is necessary to perform a perforation operation on the paper shell box. After retrieval, in the prior art (publication number: CN202322505492.7), a paper shell perforation device for the production of packaging cartons is disclosed. It is recorded in the document that "in this paper shell perforation device for the production of packaging cartons, through the setting of the perforation assembly, first place the cardboard to be perforated above the placement plate, and then through the operation of the hydraulic cylinder, drive the sliding frame to move downward, so that the bottom of the concave-shaped sliding plates on both sides of the bottom of the sliding frame first contacts the cardboard. As the sliding frame continues to move downward, the perforation shafts on both sides penetrate into the cardboard. The concave-shaped sliding plates can move upward inside the sliding frame under force, stretching the spring body, and always maintaining a downward pressure on the cardboard until the spring body resets after the perforation is completed, positioning the cardboard, effectively avoiding the phenomenon of movement and deviation during the cardboard perforation process, and ensuring the perforation accuracy of the equipment". However, in the prior art, when the sliding frame drives the perforation shaft to move downward, the stretched spring body is prone to pulling the concave-shaped sliding plate upward, affecting the smooth downward pressure on the paper shell board. Content of the Utility Model

[0003] To overcome the defects existing in the prior art, the present utility model provides a paper shell perforation device for preventing deviation to solve the problem that when the sliding frame drives the perforation shaft to move downward in the prior art, the stretched spring body is prone to pulling the concave-shaped sliding plate upward, affecting the smooth downward pressure on the paper shell board.

[0004] To achieve the above object, a paper shell perforation device for preventing deviation is provided, including: a paper shell perforation machine base and a perforation tool. The upper end of the paper shell perforation machine base is connected with a driving sliding frame through a frame, and the lower end of the driving sliding frame is equipped with a perforation tool through a fixing plate.

[0005] Pressing rollers are symmetrically distributed on the left and right sides of the perforation tool. The front and rear sides of the pressing rollers are connected with limiting frames, and the limiting frames are limited and penetrated and connected to the upper surface of the fixing plate. Baffle plates are fixed on the roller surfaces on the left and right sides of the pressing rollers. An L-shaped pushing plate is inlaid and connected to the upper table surface of the paper shell perforation machine base through an electric guide rail. Suction groove holes are formed on the upper plate surface of the L-shaped pushing plate, and the rear end of the L-shaped pushing plate is connected with a vacuum pump through a vacuum tube.

[0006] Further, the lower end of the driving carriage is connected to a fixing plate through an electric push rod. A punching machine is fixedly embedded in the middle of the fixing plate, and a punching tool is installed at the lower end of the punching machine.

[0007] Further, a stepping motor is fixed to the left end of the frame, and two lead screws are installed on the front groove surface of the frame; and the left end of the lead screw is axially connected to the stepping motor.

[0008] Further, the surface of the lead screw is connected to a clamping plate through a driving block, and the lower ends of the clamping plates are symmetrically attached to the tabletop of the paper shell punching machine base.

[0009] Further, a distance sensor is installed at the upper end of the rear side plate surface of the L-shaped push plate. The lower surface of the L-shaped push plate is connected to an electric guide rail through a slider; and the electric guide rail is embedded and installed inside the paper shell punching machine base.

[0010] Further, a vacuum pump is arranged on the upper end surface of the frame, and the vacuum tube is communicated with the adsorption groove hole through the inner cavity of the L-shaped push plate.

[0011] Further, the punching tool, the fixing plate, the pressing roller, the limiting frame and the material blocking plate form an anti-offset punching mechanism.

[0012] The beneficial effect of the present utility model is that the anti-offset paper shell punching device of the present utility model uses a pressing roller to be slidably connected to the side end of the punching tool, and the pressing roller presses down on the two side end faces of the punching position of the paper shell board by its own weight, so that the pressing roller assists in pressing the paper shell board during the punching process of the punching tool until the punching tool moves out of the paper shell board and drives the pressing roller to move up and separate, which is convenient for stably pressing the paper shell board during the punching process, effectively preventing the deviation of the punching hole position caused by the offset of the paper shell board, ensuring the smooth and accurate punching operation of the paper shell punching device. The L-shaped push plate drives the adsorbed paper shell board to move back and forth to adjust the front and rear punching positions of the paper shell board, further ensuring the accuracy of the paper shell punching position and reducing the punching deviation of the punching device.

[0018] Refer to Figures 1 to 4 As shown, the present utility model provides a paper shell perforating device for preventing deviation, including: a paper shell perforating machine base 1 and a perforating tool 2. The upper end of the paper shell perforating machine base 1 is connected with a driving carriage 22 through a frame 11, and the lower end of the driving carriage 22 is assembled with a perforating tool 2 through a fixed plate 21.

[0019] Pressing rollers 3 are symmetrically distributed on the left and right sides of the perforating tool 2. Limiting frames 31 are connected to the front and rear sides of the pressing rollers 3. The limiting frames 31 are connected through the upper surface of the fixed plate 21 in a limiting manner. Material blocking plates 32 are fixed on the left and right roller surfaces of the pressing rollers 3. An L-shaped push plate 4 is inlaid and connected to the upper table surface of the paper shell perforating machine base 1 through an electric guide rail 42. Adsorption slot holes 41 are formed on the upper plate surface of the L-shaped push plate 4. The rear end of the L-shaped push plate 4 is connected with a vacuum pump 44 through a vacuum tube 43.

[0020] During use, first place the paper shell board on the upper table surface of the paper shell perforating machine base 1, clamp the paper shell board with two groups of clamping plates 5, and press against the rear side plate surface of the L-shaped push plate 4. After adjusting and positioning the high punching position, the electric push rod 23 pushes the pressing roller 3 and the perforating tool 2 to move downward, so that the pressing roller 3 first contacts and presses the paper shell board, and then the perforating tool 2 perforates the surface of the paper shell board. After the perforation is completed, the perforating tool 2 moves out of the surface of the paper shell board. At this time, the pressing roller 3 is still in the downward pressing state. Adjust the position of the perforating tool 2 left and right again, so that the pressing roller 3 rolls on the surface of the paper shell board. During this process, the pressing roller 3 is in the downward pressing state all the time, ensuring that the paper shell board does not deviate during the perforation process.

[0021] In this embodiment, the lower end of the driving carriage 22 is connected with a fixed plate 21 through an electric push rod 23. A perforating machine 24 is embedded and fixed in the middle of the fixed plate 21, and a perforating tool 2 is installed at the lower end of the perforating machine 24.

[0022] As a preferred implementation manner, the electric push rod 23 pushes the fixed plate 21 to move downward, so that the pressing roller 3 first contacts and presses the paper shell board, and the perforating machine 24 drives the perforating tool 2 to perform a perforation operation on the surface of the paper shell board.

[0023] In this embodiment, a stepping motor 12 is fixed to the left end of the frame 11, and two sets of lead screws 52 are installed on the front slot surface of the frame 11; and the left end of the lead screw 52 is pivotally connected to the stepping motor 12. The surface of the lead screw 52 is connected to a clamping plate 5 through a driving block 51, and the lower ends of the clamping plate 5 are symmetrically attached to the upper surface of the paper shell perforating machine base 1.

[0024] As a preferred embodiment, the stepping motor 12 drives the two sets of lead screws 52 to rotate synchronously, so that the driving block 51 converts the rotational motion into a linear motion, driving the two sets of clamping plates 5 to move synchronously towards the middle or towards both sides, facilitating the clamping and restricting of the left and right displacement of the paper shell plate on the upper surface of the paper shell perforating machine base 1.

[0025] In this embodiment, a distance sensor 45 is installed at the upper end of the rear side plate surface of the L-shaped push plate 4, and the lower surface of the L-shaped push plate 4 is connected to the electric guide rail 42 through a slider; and the electric guide rail 42 is embedded and installed inside the paper shell perforating machine base 1. A vacuum pump 44 is arranged on the upper end surface of the frame 11, and a vacuum tube 43 is communicated with the adsorption groove hole 41 through the inner cavity of the L-shaped push plate 4.

[0026] As a preferred embodiment, the distance sensor 45 is used to detect the moving distance of the L-shaped push plate 4, so as to control the L-shaped push plate 4 to stop moving when it reaches a suitable position. The vacuum pump 44 generates negative pressure at the adsorption groove hole 41 through the vacuum tube 43, adsorbing the paper shell plate on the surface of the L-shaped push plate 4, preventing the paper shell plate from shifting during the movement, and facilitating the prevention of shifting when adjusting the position of the paper shell plate.

[0027] In this embodiment, the perforating tool 2, the fixing plate 21, the pressing roller 3, the limiting frame 31 and the baffle plate 32 constitute an anti-offset perforating mechanism.

[0028] As a preferred embodiment, the anti-offset perforating mechanism facilitates the stable pressing of the paper shell plate during the perforating process, effectively preventing the deviation of the perforating hole position caused by the offset of the paper shell plate, and ensuring the smooth and accurate perforating operation of the paper shell perforating device.

[0029] The anti-offset paper shell perforating device of the present utility model can effectively solve the problem that the stretched spring body is prone to pulling the concave-shaped slide plate upwards, affecting the smooth pressing of the paper shell plate, facilitating the stable pressing of the paper shell plate during the perforating process, effectively preventing the deviation of the perforating hole position caused by the offset of the paper shell plate, ensuring the smooth and accurate perforating operation of the paper shell perforating device, further ensuring the accuracy of the paper shell perforating position, reducing the perforating deviation of the perforating device, and being applicable to the anti-offset paper shell perforating device.
