Description

Technical Field

[0001] This utility model relates to the field of cardboard punching technology, and more specifically, to a cardboard positioning punching device for carton packaging processing. Background Technology

[0002] The demand for corrugated cardboard packaging is increasing, affecting a wider range of industries. During the processing of corrugated boxes, punching is required on the cardboard. Current punching methods often involve manually placing the cardboard under the punch and controlling the punching mechanism to make the holes. For example, patent CN221249966U discloses a punching device for cardboard packaging. This device uses a linkage mechanism to link the punching and positioning mechanisms, allowing the positioning mechanism to simultaneously position the cardboard while the punching mechanism is punching, eliminating the need for pre-fixing the cardboard. After punching, the positioning mechanism is reset by the compression spring of the linkage mechanism, allowing it to simultaneously release the cardboard after punching, thus eliminating the need to remove the positioning element from the cardboard. However, this device requires moving the cardboard to determine the punching position, which can easily lead to positional deviations. Therefore, we propose a cardboard positioning and punching device for cardboard packaging processing. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] Please see Figure 1-4 A cardboard positioning and punching device for cardboard packaging processing includes a base 1, a positioning mechanism 2 on the top surface of the base 1 for fixing the cardboard, a support frame 3 on the base 1, and a punching mechanism 4 installed on the support frame 3 for punching holes in the cardboard; wherein the punching mechanism 4 is slidably engaged with the support frame 3, and the punching mechanism 4 can move along the support frame 3 to adjust the position of the punching mechanism 4.

[0024] The positioning mechanism 2 includes a support platform 201, with movable frames 202 arranged opposite each other on both sides of the support platform 201. Multiple positioning blocks 203 are slidably connected to the inner side of the movable frames 202. Grooves are formed in the inner wall of the movable frames 202, and the sides of the positioning blocks 203 slide in these grooves, allowing the positioning blocks 203 to move only vertically. An elastic element 204 is provided on the top surface of the positioning blocks 203, with its upper end connected to the inner bottom surface of the movable frames 202. The elastic element 204 is a spring. The elastic element 204 buffers the force applied to the cardboard, preventing excessive pressure from damaging the cardboard. A rubber shaft 205 is rotatably connected to the bottom of the positioning blocks 203. The rubber shaft 205 increases friction with the cardboard when it is pressed, and pushes the cardboard forward when it is released, changing the punching position.

[0025] In this application, a guide rail 208 is provided in the middle of the support platform 201, and a lead screw is provided inside the guide rail 208. The lead screw has two threaded sections with opposite thread directions. A motor 209 is provided on the side of the support platform 201, and the output shaft of the motor 209 is connected to the lead screw. A slider B is connected in the middle of the movable frame 202. The slider B is threadedly connected to the threaded section of the lead screw and slides with the guide rail 208. The motor 209 drives the lead screw to rotate, so that the slider B, which is threaded with the lead screw, moves linearly along the lead screw. By setting two threaded sections with opposite directions, the two sliders B can move relative to each other, so that the two movable frames 202 can move relative to each other. The distance between the movable frames 202 can be adjusted according to the size of the cardboard.

[0026] In this application, the bottom of both ends of the movable frame 202 is connected to a slider A206, and a groove 207 is provided on the support platform 201. The slider A206 and the groove 207 slide in cooperation. The extension direction of the groove 207 is perpendicular to the extension direction of the movable frame 202. The movement direction of the movable frame 202 is restricted by the setting of the groove 207.

[0027] In this application, multiple positioning blocks 203 are provided with connecting rods, and hydraulic rods are provided on the top surface of the connecting rods. The hydraulic rods are installed on the bottom surface of the movable frame 202. The hydraulic rods are used to extend and retract to drive multiple positioning blocks 203 to move vertically and press the cardboard. At the same time, the springs are also designed to accommodate cardboards of different thicknesses for fixing.

[0028] In this application, the punching mechanism 4 includes a cylinder 401, a movable shaft 402, a punching head 403, and a mounting bracket 404. The output shaft of the cylinder 401 is connected to the movable shaft 402, and the movable shaft 402 is movably connected to the punching head 403. The cylinder 401 is mounted on the mounting bracket 404, which is slidably engaged with the top of the support frame 3. The mounting bracket 404 and the top of the support frame 3 are slidably engaged via an electric slide rail. The position of the mounting bracket 404 can be adjusted via the electric slide rail, and the direction of movement of the electric slide rail is the same as the direction of movement of the movable frame 202. By moving the mounting bracket 404, the punching head 403 is moved, and the punching position is adjusted. At the same time, the cardboard moves on the support table 201, which can precisely adjust the punching position.

[0029] In one possible scenario, a hollow cavity is formed inside the punch head 403 along its axis, and a laser light is installed at the lower end of the movable shaft 402. The light source of the laser light can be projected onto the cardboard from the hollow cavity inside the punch head 403, thereby accurately determining whether the punching position is accurate.

[0030] Working principle:

[0031] In use, this utility model controls the movement of the punching mechanism 4 via an electric slide rail, which, in conjunction with the movement of the cardboard on the support platform 201, allows for precise adjustment of the punching position. When processing packaging cartons, the cardboard to be punched is placed on the support platform 201. The motor 209 drives the lead screw to rotate, causing the slider B, which is threaded with the lead screw, to move linearly along the lead screw. The two sliders B can move relative to each other through the setting of two threaded sections in opposite directions, thereby causing the two moving frames 202 to move relative to each other. The moving frames 202 are moved to above the edge of the cardboard, and then the hydraulic rod is used to extend and retract to drive multiple positioning blocks 203 to move vertically, pressing the cardboard tightly. The spring setting prevents excessive pressure from damaging the cardboard, and the spring setting also facilitates the fixing of cardboard with different thicknesses at different positions, so that the punching position of the cardboard is below the punching head 403. Finally, the output shaft of the cylinder 401 pushes the movable shaft 402 to move. The movable shaft 402 slides relative to the mounting frame 404, thereby pushing the punching head 403 downward to punch the cardboard.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
