Technical Field

[0001] This utility model relates to an automatic cutting device for paper cup production. Background Technology

[0002] In the paper cup production process, the paper cup blank needs to be stamped out to the required size and shape for making paper cups using stamping parts. In the existing technology, the paper is simply fixed between the stamping molds and then stamped. During stamping, because the cup body is not properly positioned and pressed, it is easy for the stamped cup body to have rough edges and dimensional deviations. Utility Model Content

[0003] This invention provides an automatic cutting device for paper cup production.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic cutting device for paper cup production, including a stamping assembly, the stamping assembly including a punch unit and a base, the punch unit being disposed directly above the base;

[0005] The punch unit includes a guide frame with a fan-shaped cross-section. An X-shaped bracket is located inside the guide frame and connected to the inner side of the guide frame. A push rod is located at the intersection of the brackets, perpendicular to the plane of the bracket. An annular cutter with the same shape as the guide frame and a U-shaped cross-section is provided around the guide frame. A spring is located within the groove of the U-shaped cross-section of the cutter. One end of the bracket extends into the groove of the U-shaped cross-section. One end of the spring is connected to the bracket, and the other end of the spring is connected to the inside of the groove of the cutter. The spring is in a compressed state.

[0006] The base is provided with a guide groove that matches the cutter. The shape of the guide groove is the same as that of the cutter. Four guide posts are provided on the upper surface of the base. All four guide posts are located in the guide groove. The guide posts are perpendicular to the upper surface of the base. The bracket is provided with four guide rings, which are respectively fitted onto the four guide posts.

[0007] Preferably, the cutter has a limiting block at the groove opening and a boss on the inner side of the cutter, the boss matching the limiting block.

[0008] Preferably, the cutter is fitted to the bracket, and the minimum horizontal height of the cutter is less than the minimum horizontal height of the bracket.

[0009] The beneficial effects of this utility model are that the automatic cutting device for paper cup production drives the stamping components up and down through an external drive mechanism, thereby causing the cutter to move up and down along the guide frame and cooperate with the base to perform the cutting operation. During cutting, the guide frame fixes the cutting edge of the paper, improving the stability and cutting accuracy. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-4 As shown, an automatic cutting device for paper cup production includes a stamping assembly, which includes a punch unit and a base 4, with the punch unit disposed directly above the base 4.

[0018] The punch unit includes a guide frame 5 with a fan-shaped cross-section. A bracket 6, which is X-shaped, is located inside the guide frame 5 and connected to the inner side of the guide frame 5. A push rod 2 is located at the intersection of the brackets 6, perpendicular to the plane of the bracket 6. An annular cutter 1, identical in shape to the guide frame 5, has a U-shaped cross-section. A spring 8 is located within the groove of the U-shaped cross-section of the cutter 1. One end of the bracket 6 extends into the groove of the U-shaped cross-section. One end of the spring 8 is connected to the bracket 6, and the other end is connected to the inside of the groove of the cutter 1. The spring 8 is in a compressed state.

[0019] The base 4 is provided with a guide groove that matches the cutter 1. The shape of the guide groove is the same as that of the cutter 1. Four guide posts 3 are provided on the upper surface of the base 4. All four guide posts 3 are located in the guide groove. The guide posts 3 are perpendicular to the upper surface of the base 4. The bracket 6 is provided with four guide rings 7. The four guide rings 7 are respectively sleeved on the four guide posts 3.

[0020] Preferably, the cutter 1 has a limiting block 9 at the groove opening, and the inner side of the cutter 1 has a boss that matches the limiting block 9.

[0021] Preferably, the cutter 1 is fitted to the bracket 6, and the minimum horizontal height of the cutter 1 is less than the minimum horizontal height of the bracket 6.

[0022] During cutting, the push rod 2 is driven by an external drive component, such as a cylinder, causing the guide frame 5 and the cutter 1 to move downwards synchronously. Since the guide frame 5 is at a lower horizontal height, it will contact the paper to be cut first. As the push rod 3 moves further downwards, the bracket 6 will push the blade 1 further downwards along the guide frame 5. The spring 8 will press the guide frame 5 downwards, so that the guide frame 5 can fix the target cutting part. Then the blade 1 will cut. Since the guide frame 5 and the blade 1 have the same shape, the pressure shape of the guide frame 5 is actually in close contact with the finished cutting edge. This makes the cutting more precise and stable, and it is also conducive to cutting in one piece and reducing the generation of burrs.

[0023] The cooperation between the four guide pillars 2 and the guide ring 7 is mainly to improve the accuracy and stability of the upper and lower mold closing during the stamping process.

[0024] In fact, the guide frame 5 and the cutter 1 have the same shape and fit together. The function of the guide frame 5 is to hold the target paper in place while providing stable and precise guidance for the cutter 1.

[0025] Compared with existing technologies, this automatic cutting device for paper cup production uses an external drive mechanism to drive the stamping components up and down, thereby causing the cutter 1 to move up and down along the guide frame 5 and cooperate with the base 4 to perform the cutting operation. During cutting, the guide frame 5 fixes the cutting edge of the paper, improving the stability and cutting accuracy.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
