Description

Technical Field

[0001] This utility model relates to the field of paper cup holder processing technology, specifically a pressing device for paper cup holder processing. Background Technology

[0002] Paper cup holders, as commonly used paper packaging supports in the catering industry, require key processing steps such as raw material cutting and pressing. Among these, the pressing process directly determines the structural stability, edge smoothness, and production efficiency of the paper cup holder. This is especially true as the food packaging industry continues to demand higher standards for product standardization and production automation.

[0003] Currently, most paper cup holder pressing devices on the market rely on manual operation for blank feeding. That is, the operator needs to lay the rolled paper blanks flat on the pressing mold section by section. This is not only labor-intensive, but also causes blank positioning deviation due to human operation errors, resulting in paper cup holder forming defects. At the same time, during the manual feeding process, the operator needs to frequently approach the running pressing mechanism, which poses a safety risk of hand crushing. In addition, the existing mold fixing methods mostly use bolt locking, which requires the use of additional tools. Therefore, this utility model provides a pressing device for paper cup holder processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressing device for paper cup holder processing. It solves the problem that most paper cup holder pressing devices on the market rely on manual operation for blank feeding. That is, the operator needs to lay the rolled paper blanks section by section on the pressing mold, which is not only labor-intensive, but also causes blank positioning deviation due to human operation errors, resulting in paper cup holder forming defects. At the same time, during the manual feeding process, the operator needs to frequently approach the running pressing mechanism, which poses a safety risk of hand crushing. In addition, the existing mold fixing methods mostly use bolt locking, which requires the use of additional tools for operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing device for processing paper cup holders, comprising a mounting base, wherein the mounting base is provided with a mounting mechanism for pressing paper cup holders during processing, the mounting mechanism comprising:

[0006] The mounting components include a positioning frame fixed to the upper surface of the mounting base, a mold base inserted inside the positioning frame, locking grooves on both sides of the mold base, and locking brackets connected by threaded components inside the locking grooves.

[0007] The feeding assembly includes a support plate fixed to the upper surface of a mounting base. A support roller for placing blanks is rotatably connected to the upper surface of the support plate. Vertical plates are fixed to both sides of the support plate. A limiting plate connected by a telescopic component is provided inside the vertical plate. A top plate is fixed to the upper end of the vertical plate. A support shell connected by a drive component is provided on the upper surface of the top plate. A rubber ring block connected by an elastic component is provided inside the support shell.

[0008] Preferably, the threaded assembly includes a sliding groove inside the mounting base, a bidirectional lead screw is rotatably connected inside the sliding groove, the locking bracket is slidably connected to the inner wall of the sliding groove, the locking bracket is threadedly connected to the bidirectional lead screw, and two sets of locking brackets are provided.

[0010] Preferably, the telescopic assembly includes an electric push rod that is fixedly inserted through the interior of a vertical plate, and a limiting plate is fixedly connected to the telescopic end of the electric push rod. The limiting plate is configured as two sets located on both sides of the support roller shaft.

[0011] Preferably, the drive assembly includes a motor fixed to the upper surface of the top plate, a rotating base fixed to the output end of the motor, and two sets of support housings located inside the rotating base.

[0013] Beneficial effects

[0014] This invention provides a pressing device for processing paper cup holders. Compared with the prior art, it has the following advantages:

[0015] Firstly, the motor on the starting plate of this invention drives the rotating seat at the output end to rotate. The rotating seat drives two sets of supporting shells to move synchronously in a circular motion. When the rubber ring on the slide rod is released from the blank, the spring inside the supporting shell is in a compressed state. The slide rod applies continuous pressure to the rubber ring, making the rubber ring tightly fit the upper surface of the blank. As the rotating seat rotates, the rubber ring drives the blank to move along the axis of the supporting roller towards the mold seat through friction. When the blank is conveyed to the top of the mold seat, the motor stops and the feeding process stops. After the pressing process is completed, the motor starts again to perform the next feeding, reducing frequent manual operation and thus avoiding accidental injury to workers during equipment processing. In addition, the elastic buffering effect of the spring allows the rubber ring to adapt to the slight undulations on the surface of the blank, and it is compatible with blanks of different thicknesses, eliminating the need for frequent replacement of feeding parts and improving adaptability.

[0016] Secondly, this utility model inserts a mold base of the appropriate specification along the inner side of the positioning frame. Utilizing the contour constraint of the positioning frame, the mold base is initially positioned, ensuring that it is coaxially aligned with the upper pressing block. The moving bidirectional lead screw, due to the threaded connection between the locking bracket and the bidirectional lead screw and the limitation of the sliding groove, allows the two sets of locking brackets to slide towards each other along the sliding groove until they are embedded in the locking grooves on both sides of the mold base. The mold base is fixed by the self-locking characteristic of the thread, completing the mold installation. If the mold needs to be replaced, the bidirectional lead screw is rotated in the opposite direction, and the two sets of locking brackets disengage from the locking grooves, allowing the old mold base to be pulled out upwards. This facilitates mold replacement according to processing needs without the need for additional tools, adapting to the production needs of multiple specifications of paper cup holders.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a pressing device for processing paper cup holders, including a mounting base 1, on which a mounting mechanism for pressing paper cup holders is provided, the mounting mechanism including:

[0024] The mounting components include a positioning frame 4 fixed to the upper surface of the mounting base 1, a mold base 401 inserted inside the positioning frame 4, locking grooves 402 on both sides of the mold base 401, and a locking bracket 405 connected by a threaded assembly inside the locking grooves 402.

[0025] The feeding assembly includes a support plate 5 fixed to the upper surface of the mounting base 1. A support roller shaft 501 for placing the blank is rotatably connected to the upper end of the support plate 5. Vertical plates 502 are fixed on both sides of the support plate 5. A limiting plate 504 connected by a telescopic component is provided inside the vertical plate 502. A top plate 6 is fixed to the upper end of the vertical plate 502. A support shell 603 connected by a drive component is provided on the upper surface of the top plate 6. A rubber ring block 607 connected by an elastic component is provided inside the support shell 603.

[0026] In a preferred embodiment, the threaded assembly includes a groove 403 inside the mounting base 1. A bidirectional lead screw 404 is rotatably connected inside the groove 403. A locking bracket 405 is slidably connected to the inner wall of the groove 403. The locking bracket 405 is threadedly connected to the bidirectional lead screw 404. Two sets of locking brackets 405 are configured. A mold base 401 of the appropriate specification is inserted along the inner side of the positioning frame 4. The contour constraint of the positioning frame 4 is used to achieve the initial positioning of the mold base 401, ensuring that it is coaxially aligned with the upper pressing block 301. Rod 404, because the locking bracket 405 is threadedly connected to the bidirectional lead screw 404 and limited by the slide groove 403, the two sets of locking brackets 405 slide towards each other along the slide groove 403 until they are embedded in the locking grooves 402 on both sides of the mold seat 401. The mold seat 401 is fixed by the self-locking characteristic of the thread, and the mold installation is completed. If the mold needs to be replaced, the bidirectional lead screw 404 is rotated in the opposite direction, and the two sets of locking brackets 405 are disengaged from the locking grooves 402, and the old mold seat 401 can be pulled out upwards. It is convenient to replace the mold according to the processing needs without the need for additional tools.

[0027] In a preferred embodiment, support frames 2 are fixed on both sides of the mounting base 1. A hydraulic rod 201 is fixed to the upper end of the support frame 2, and a mounting plate 202 is fixed to the lower end of the hydraulic rod 201. Four sets of guide rods 203 for sliding the mounting plate 202 are fixed to the upper surface of the mounting base 1. A mounting bracket 3 connected by bolts is attached to the lower surface of the mounting plate 202. A pressing block 301 is fixed to the lower surface of the mounting bracket 3. A ring cutter 302 is fixed to the outer side of the pressing block 301 located on the lower surface of the mounting bracket 3. During processing, the hydraulic rod 201 on the support frame 2 is activated, and the hydraulic rod 201 drives the lower mounting plate 202 to slide vertically downward along the four sets of guide rods 203. To ensure the stability of the pressing process, the mounting plate 202 moves the pressing block 301 downwards synchronously through the mounting bracket 3 connected by bolts. The pressing block 301 first contacts the paper blank on the mold base 401 and shapes and presses the blank. As the mounting plate 202 continues to move downwards, the ring cutter 302 fixed at the lower end of the mounting bracket 3 fits against the edge of the blank, separating the pressed paper cup holder from the corner waste, completing one pressing process. The shaping of the pressing block 301 and the cutting of the ring cutter 302 are completed simultaneously, eliminating the need for a separate cutting process and improving work efficiency. After pressing is completed, the hydraulic rod 201 drives the mounting plate 202 and related components to return to their original position, waiting for the next processing cycle.

[0028] In a preferred embodiment, the telescopic assembly includes an electric push rod 503 fixedly inserted inside a vertical plate 502, and a limiting plate 504 fixedly connected to the telescopic end of the electric push rod 503. The limiting plates 504 are configured as two sets located on both sides of the support roller shaft 501. According to the width specification of the paper blank, the electric push rod 503 fixedly inserted inside the vertical plate 502 is activated. The electric push rod 503 drives the limiting plate 504 at the telescopic end to move along the length direction of the support roller shaft 501. The two sets of limiting plates 504 are adjusted to face each other or back to back until the spacing matches the width of the blank. The lateral constraint of the limiting plate 504 prevents the blank from shifting laterally during the conveying process.

[0029] In a preferred embodiment, the driving assembly includes a motor 601 fixed to the upper surface of the top plate 6, a rotating seat 602 fixed to the output end of the motor 601, and two sets of supporting housings 603 located inside the rotating seat 602. The elastic assembly includes a spring 604 fixed to one end inside the supporting housing 603, a sliding rod 606 fixed to one end of the spring 604, the sliding rod 606 being slidably connected to the interior of the supporting housing 603, and a telescopic sleeve 605 provided on the inner ring of the spring 604. 05 is fixedly connected at both ends to the support housing 603 and the slide rod 606 respectively. The rubber ring block 607 is fixedly connected at the other end of the slide rod 606. When the rubber ring block 607 rotates, it contacts the blank on the support roller shaft 501 to push and feed it. One end of the rolled paper blank is laid flat on the support roller shaft 501 at the upper end of the support plate 5. The edge of the blank is attached to the inner side of the two sets of limiting plates 504. The support roller shaft 501 reduces the friction during blank conveying by rotating. The motor 601 on the top plate 6 is started. The motor 601 drives the rotating seat 602 at the output end to rotate. The rotating seat 602 drives the two sets of supporting shells 603 to move synchronously in a circular motion. When the rubber ring block 607 on the slide rod 606 is released from the blank, the spring 604 inside the supporting shell 603 is in a compressed state. The slide rod 606 applies continuous pressure to the rubber ring block 607, making the rubber ring block 607 tightly fit the upper surface of the blank. As the rotating seat 602 rotates, the rubber ring block 607 drives the blank along the support roller shaft 501 towards the mold seat 401 through friction. When the blank is delivered to the top of the mold seat 401, the motor 601 stops, and the feeding process stops. After the pressing process is completed, the motor 601 starts again to perform the next feeding, reducing frequent manual operation and thus avoiding accidental injury to the workers during equipment processing. In addition, the elastic buffering effect of the spring 604 allows the rubber ring block 607 to adapt to the slight undulations on the surface of the blank, and is compatible with blanks of different thicknesses. It eliminates the need for frequent replacement of feeding parts and improves adaptability.

[0030] The telescopic sleeve 605 extends and retracts synchronously, ensuring that the slide rod 606 slides smoothly along the supporting shell 603.

[0031] Among the above-mentioned electric actuators, the model DT50-12-200 can be selected, the hydraulic actuator model HOB63x200 can be selected, and the motor model is 57BYGH56-401A.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, the mold base 401 of the appropriate specification is inserted into the inner side of the positioning frame 4 fixed on the upper end face of the mounting base 1. The initial positioning is achieved by using the contour constraint of the positioning frame 4 to ensure that it is coaxially aligned with the upper pressing block 301. Then, the bidirectional screw 404 in the sliding groove 403 inside the mounting base 1 is rotated. Because the two sets of locking brackets 405 are threadedly connected to the bidirectional screw 404 and are limited by the sliding groove 403, the two sets of locking brackets 405 slide towards each other along the sliding groove 403 until they are embedded in the locking grooves 402 on both sides of the mold base 401. The mold base 401 is fixed by the thread self-locking characteristic, and the mold installation is completed.

[0034] Next, the blank positioning adjustment is performed: Based on the width specifications of the paper blank, the electric push rods 503, which are fixed through the vertical plates 502 on both sides of the support plate 5, are activated. The electric push rods 503 drive the two sets of limiting plates 504 at the telescopic end to move towards or away from each other along the length of the support roller shaft 501 until the spacing matches the blank width. The lateral constraint of the limiting plates 504 prevents lateral deviation of the blank during transport. Then, the feeding process is started.

[0035] One end of the rolled paper blank is laid flat on the support roller shaft 501 at the upper end of the support plate 5, so that the edge of the blank is in contact with the inner side of the two sets of limiting plates 504. The support roller shaft 501 reduces the conveying friction by rotating. At the same time, the motor 601 fixed on the upper end of the top plate 6 is started. The motor 601 drives the rotating seat 602 at the output end to rotate, which drives the two sets of support shells 603 on the rotating seat 602 to move synchronously in a circular motion. The spring 604 inside the support shell 603 is in a compressed state. The slide rod 606 applies continuous pressure to the rubber ring block 607, so that it is tightly attached to the upper surface of the blank. As the rotating seat 602 rotates, the rubber ring block 607 drives the blank along the support roller shaft 501 towards the mold seat 401 through friction. During this process, the telescopic sleeve 605 extends and retracts synchronously to ensure that the slide rod 606 slides smoothly along the support shell 603. When the blank is conveyed to the top of the mold seat 401, the motor 601 stops and the feeding stops.

[0036] Finally, the pressing process is initiated: The hydraulic rods 201 on the support frames 2 on both sides of the mounting base 1 are activated. The hydraulic rods 201 drive the mounting plate 202 at the lower end to slide vertically downward along the four sets of guide rods 203. The mounting plate 202 drives the pressing block 301 to move down synchronously through the mounting bracket 3 connected by bolts. The pressing block 301 first contacts the blank on the mold seat 401 for shaping and pressing. As the mounting plate 202 continues to move down, the ring cutter 302 fixed at the lower end of the mounting bracket 3 fits against the edge of the blank, separating the pressed paper cup holder from the corner waste, completing one pressing process. Afterward, the hydraulic rods 201 drive the mounting plate 202 and related components to return to the starting position. The motor 601 starts again for the next feeding, and the cycle is completed continuously. If the mold needs to be replaced, the bidirectional lead screw 404 is rotated in the opposite direction, and the two sets of locking brackets 405 are disengaged from the locking groove 402, so the old mold seat 401 can be pulled out upward. The above mold installation steps are repeated to replace the new mold seat 401.
