Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, and in particular to a disposable paper cup holder for paper cup production. Background Technology

[0002] On the paper cup production line, disposable paper cup racks play a crucial role, serving as key auxiliary equipment to ensure a smooth and efficient production process.

[0003] In the paper cup production process, the placement and fixing of paper cups by the rack is a crucial step in ensuring orderly production. However, this step currently suffers from significant technical shortcomings: due to the substantial differences in the specifications of disposable paper cups, encompassing various diameters, heights, and cup curvature designs, traditional racks often have fixed-size positioning structures. This limitation prevents flexible adjustments based on cup specifications, making it difficult to achieve precise contact with the cup surface during positioning, often resulting in excessive gaps or over-compression in certain areas. When the positioning force is uneven, the paper cup surface is prone to deformation problems such as dents and wrinkles due to concentrated stress. This not only directly affects the product's appearance and flatness but also increases the probability of defective products, negatively impacting production efficiency and cost control. Therefore, we propose a disposable paper cup rack for paper cup production to address the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a disposable paper cup holder for paper cup production, which can solve the problem that limiting and fixing paper cups in the paper cup production process is a crucial step in ensuring the orderly progress of production. However, there are obvious technical shortcomings in this step: due to the significant differences in the specifications of disposable paper cups, covering different diameters, heights, and cup body curvature designs, the limiting structure of traditional holders is mostly of fixed size, which cannot be flexibly adjusted according to the specifications of the paper cups. This structural limitation makes it difficult to achieve precise fit with the surface of the paper cup during limiting, often resulting in excessive gaps or excessive compression in some areas. When the limiting force is uneven, the surface of the paper cup is prone to deformation problems such as dents and wrinkles due to concentrated force, which not only directly affects the flatness of the product's appearance, but also increases the probability of producing defective products, adversely affecting production efficiency and cost control.

[0006] To solve the above-mentioned technical problems, this utility model provides a disposable paper cup holder for paper cup production, which adopts the following technical solution: it includes a first support frame, a second support frame is fixedly installed on the top of the first support frame, and a clamping component is provided on the top of the second support frame;

[0007] The clamping assembly includes four movable frames. The top of the second support frame has four first movable slots arranged in a circumferential array. The tops of the four movable frames are slidably disposed inside the corresponding first movable slots. A connecting plate is fixedly disposed on the top of each of the four movable frames. Three spring-type telescopic rods are fixedly disposed on the inner side of each connecting plate. An arc-shaped limiting plate is disposed on the inner side of each connecting plate. Each arc-shaped limiting plate is fixedly disposed at the end of the three adjacent spring-type telescopic rods away from the connecting plate.

[0008] Preferably, a drive rod is slidably disposed at the bottom of the inner cavity of the second support frame, and four side plates are fixedly disposed in a circumferential array on the outside of the drive rod, and the drive rod is located inside the second support frame.

[0009] Preferably, the bottom circumferential array of the second support frame has four second movable slots, and each second movable slot is located directly below the corresponding first movable slot.

[0010] Preferably, the bottom ends of the four movable frames are respectively embedded and slidably disposed inside the corresponding second movable slots.

[0011] Preferably, each of the movable frames is hinged to the adjacent side plate on both the front and rear sides by two connecting rods.

[0012] Preferably, a cylinder is fixedly installed at the bottom of the inner cavity of the first support frame, and the top output end of the cylinder is fixedly connected to the bottom end of the drive rod.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By driving the drive rod to rise and fall with a cylinder, the side plate and connecting rod are linked, allowing the four movable frames to slide radially synchronously along the first and second movable grooves. This allows for flexible adjustment of the encircling diameter of the arc-shaped limiting plate, adapting to disposable paper cups of different diameters. Simultaneously, the arc-shaped limiting plate is connected to the connecting plate via a spring-loaded telescopic rod. The elastic buffering effect of the spring allows the limiting plate to automatically conform to the curvature of the cup, avoiding the problems of excessive local gaps or excessive compression in traditional fixed structures. This significantly reduces the probability of dents and wrinkles in the paper cup due to uneven force, ensuring the product's smooth appearance.

[0014] 2. The automated adjustment structure of this placement rack reduces manual adjustment time when changing to different sizes of paper cups. Precise cylinder drive enables rapid switching, shortening the production preparation cycle. The three-point support design of the spring-loaded telescopic rod ensures even distribution of the limiting force, effectively reducing the probability of defective products and minimizing raw material waste and rework costs. Furthermore, the components are connected via sliding and hinged joints, resulting in a stable structure with minimal wear, extending equipment lifespan and indirectly reducing production and maintenance costs. This provides strong support for enterprises to improve production efficiency and economic benefits. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 —4. This utility model will be described in further detail.

[0023] In this embodiment, the placement and fixing of paper cups by the rack is a crucial step in ensuring the orderly progress of paper cup production. However, this step currently suffers from significant technical shortcomings: due to the substantial differences in the specifications of disposable paper cups, encompassing various diameters, heights, and cup curvature designs, the limiting structure of traditional racks is mostly of fixed size, unable to be flexibly adjusted according to the paper cup specifications. This structural limitation makes it difficult to achieve precise contact with the paper cup surface during positioning, often resulting in excessively large gaps or excessive compression in certain areas. When the limiting force is uneven, the paper cup surface is prone to deformation problems such as dents and wrinkles due to concentrated force, which not only directly affects the flatness of the product's appearance but also increases the probability of producing defective products, adversely impacting production efficiency and cost control. This utility model discloses a disposable paper cup rack for paper cup production.

[0024] It includes a first support frame 1, a second support frame 2 is fixedly installed on the top of the first support frame 1, and a clamping assembly 3 is provided on the top of the second support frame 2;

[0025] The clamping assembly 3 includes four movable frames 4. The top of the second support frame 2 has four first movable slots 5 arranged in a circular array. The tops of the four movable frames 4 are slidably disposed inside the corresponding first movable slots 5. A connecting plate 6 is fixedly disposed on the top of each of the four movable frames 4. Three spring-type telescopic rods 7 are fixedly disposed on the inner side of each connecting plate 6. An arc-shaped limiting plate 8 is provided on the inner side of each connecting plate 6. Each arc-shaped limiting plate 8 is fixedly disposed at the end of the three adjacent spring-type telescopic rods 7 away from the connecting plate 6.

[0026] Specifically: the top of the movable frame 4 is fitted into the slide rail in the first movable groove 5, and can slide horizontally along the radial direction of the groove; the connecting plate 6 has an arc-shaped plate structure, its outer side is welded and fixed to the top of the movable frame 4, and its inner plane is rigidly connected to the fixed end of the spring-type telescopic rod 7 by bolts, ensuring that the extension and retraction direction of the spring-type telescopic rod 7 always points to the central axis of the placement frame.

[0027] A drive rod 9 is slidably arranged at the bottom of the inner cavity of the second support frame 2. Four side plates 10 are fixedly arranged in a circular array on the outside of the drive rod 9, and the drive rod 9 is located inside the second support frame 2.

[0028] Specifically: the drive rod 9 is a multi-stage sleeve structure, and its bottom is slidably connected to the guide groove at the bottom of the inner cavity of the second support frame 2 through a slider, so that it can be stably extended and retracted in the vertical direction; the four side plates 10 are all rectangular metal plates, and their inner sides are fixed to the outer wall of the drive rod 9 by welding. There is an equal gap between adjacent side plates 10, and the height of the side plates 10 is adapted to the height of the inner cavity of the second support frame 2 to ensure that there is no jamming or interference during the extension and retraction process.

[0029] The bottom circumferential array of the second support frame 2 has four second movable slots 11, and each second movable slot 11 is located directly below the corresponding first movable slot 5.

[0030] Specifically, the width of the second movable groove 11 is the same as that of the first movable groove 5, and the depth is two-thirds of the wall thickness of the second support frame 2. The two sides of the groove are symmetrically provided with strip-shaped guide protrusions, which form a sliding fit with the groove at the bottom of the movable frame 4, so as to realize the dual function of vertical limiting and horizontal guiding of the movable frame 4.

[0031] The bottom ends of the four movable frames 4 are respectively embedded and slidably disposed inside the corresponding second movable slots 11;

[0032] Specifically, the bottom of the movable frame 4 is machined into a stepped structure that matches the second movable groove 11. The outer protrusion is embedded in the second movable groove 11 and slides and engages with the guide protrusion in the groove. A 5-8mm gap is reserved between the bottom of the movable frame 4 and the side plate 10 to avoid rigid friction during sliding.

[0033] Each movable frame 4 is hinged to the adjacent side plate 10 via two connecting rods 12 on both the front and rear sides.

[0034] Specifically, the connecting rod 12 is a high-strength alloy rod, and both ends are movably connected to the movable frame 4 and the lugs on the side plate 10 through bearings. A grease cavity is provided at the hinge point to ensure that the connecting rod 12 can rotate flexibly within the range of 0-60°, so as to realize the linkage transmission between the side plate 10 and the movable frame 4.

[0035] A cylinder 13 is fixedly installed at the bottom of the inner cavity of the first support frame 1, and the top output end of the cylinder 13 is fixedly connected to the bottom end of the drive rod 9.

[0036] Specifically: Cylinder 13 is a standard SC series cylinder 13, and its cylinder body is fixed to the mounting seat in the inner cavity of the first support frame 1 by bolts. The drive rod 9 is a solid chrome-plated round rod, and its top end is detachably connected to the bottom end of the drive rod 9 by a flange. A buffer pad is provided at the connection to reduce the impact load during startup.

[0037] The specific working principle is as follows: When it is necessary to limit the placement of disposable paper cups of different sizes, the cylinder 13 in the first support frame 1 is activated. The output end of the cylinder 13 drives the drive rod 9 to rise and fall vertically through the drive rod 9. When the drive rod 9 rises, the four side plates 10 on its outer wall move upward synchronously, pushing the movable frame 4 to slide along the first movable groove 5 and the second movable groove 11 towards the center of the placement frame through the connecting rod 12; conversely, when the drive rod 9 falls, the side plates 10 move downward, and the connecting rod 12 pulls the movable frame 4 to slide away from the center, realizing the synchronous radial extension and retraction adjustment of the four movable frames 4. During the movement of the movable frame 4, the connecting plate 6 drives the arc-shaped limiting plate 8 to move closer to or away from the central axis synchronously. When a paper cup is placed between four arc-shaped limiting plates 8, the arc-shaped limiting plates 8 contact the outer wall of the paper cup. At this time, the spring-type telescopic rods 7 automatically extend and retract according to the curvature of the outer wall of the paper cup: for paper cups with larger diameters, the sliding distance of the moving frame 4 is smaller, and the compression of the spring-type telescopic rods 7 is smaller; for paper cups with smaller diameters, the sliding distance of the moving frame 4 is larger, and the compression of the spring-type telescopic rods 7 increases. The elastic buffering effect of the spring-type telescopic rods 7 ensures that the arc-shaped limiting plates 8 always maintain a uniform fit with the outer wall of the paper cup, avoiding the rigid compression of traditional fixed structures. At the same time, the three spring-type telescopic rods 7 form a three-point support for the arc-shaped limiting plates 8, ensuring that the limiting force is evenly distributed along the arc-shaped limiting plates 8, effectively dispersing the force on the surface of the paper cup, and preventing deformation problems such as dents and wrinkles caused by local force concentration. Through the precise control of the cylinder 13 and the adaptive adjustment of the spring-type telescopic rods 7, this placement rack can accommodate disposable paper cups of different diameters, heights, and curvatures, achieving stable and damage-free limiting fixation, reducing the production of defective products, and improving production efficiency.
