Description

Technical Field

[0001] This invention belongs to the technical field of paper cup processing, and in particular relates to a novel high-strength, high-sealing irregular-shaped paper cup processing positioning and size detection device. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper (white cardboard) made from chemical wood pulp. They are shaped like cups. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic and can hold boiling water. Paper cups are characterized by being safe, hygienic, lightweight, and convenient.

[0003] With the diversification of market demand, the design of paper cups has become increasingly diverse. Besides traditional round paper cups, square and other irregularly shaped paper cups are increasingly widely used. Due to their irregular structure, these irregularly shaped paper cups present significantly different challenges in dimensional inspection compared to round paper cups. Currently, existing paper cup dimensional inspection equipment is mostly designed for single round paper cups, lacking versatility and unable to simultaneously meet the inspection needs of various irregularly shaped paper cups, such as round and square ones. Equipping different shaped paper cups with dedicated inspection equipment would not only significantly increase production costs but also occupy more production space, reducing the flexibility and efficiency of the inspection process. This would be insufficient to meet the current large-scale and diversified processing needs of high-strength, high-sealing, novel irregularly shaped paper cups. Therefore, this paper proposes a high-strength, high-sealing, novel irregularly shaped paper cup processing positioning and dimensional inspection device that can solve the above problems. Summary of the Invention

[0004] This invention provides a novel high-strength, high-sealing irregular-shaped paper cup processing positioning and dimensional detection device. It aims to address the challenges of dimensional detection in existing technologies. With the diversification of market demands and the increasing variety of paper cup designs, the use of irregular-shaped paper cups such as square cups is becoming more widespread, in addition to traditional round cups. The irregular structure of these irregular-shaped cups presents significantly different dimensional detection difficulties compared to round cups. Currently, existing paper cup dimensional detection equipment is mostly designed for single round paper cups, lacking versatility and unable to simultaneously adapt to the detection needs of various irregular-shaped paper cups, such as round and square cups. Equipping different shaped paper cups with dedicated detection equipment would not only significantly increase production costs but also occupy more production space, reducing the flexibility and efficiency of the detection process, making it difficult to meet the current large-scale and diversified processing needs of high-strength, high-sealing novel irregular-shaped paper cups.

[0005] The present invention is implemented as follows: a novel high-strength and high-sealing irregular-shaped paper cup processing positioning and size detection device, comprising: a base, on which a rotating unit for driving the paper cup to rotate is provided, a first clamping unit disposed on the rotating unit, a detection machine disposed above the base, and a second clamping unit disposed above the base, wherein the first clamping unit and the second clamping unit are used to clamp the paper cup body.

[0006] Preferably, the lower end of the base is fixedly connected to multiple support legs.

[0007] Preferably, the rotating unit includes a rotating ring disposed on the base, and the rotating ring itself is capable of rotation.

The rotating plate is provided with a through groove that mates with the slots. A first clamping plate is inserted into the slot, and a clamping curved surface is provided on the first clamping plate.

[0009] Preferably, the first clamping plate is an elastic plate.

[0013] Compared with existing technologies, the coordinated operation of the first and second clamping units, combined with a detachable and adjustable structural design, enables the device to adapt to the positioning and clamping needs of various irregularly shaped paper cups, such as round and square cups, as well as paper cups of different sizes. This solves the problem of poor versatility of existing testing equipment, eliminating the need for dedicated testing equipment for paper cups of different shapes, significantly reducing production input costs and production space occupation.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This invention provides a novel high-strength, high-sealing device for processing, positioning, and dimensional detection of irregularly shaped paper cups, such as... Figures 1-8 As shown, the specific structure is as follows: The device includes a base 1, a rotating unit, a first clamping unit, a detection machine 2, and a second clamping unit. These components work together to position, clamp, and detect the dimensions of irregularly shaped paper cups. The specific implementation is as follows: The base 1, serving as the mounting foundation for the entire device, is made of high-strength stainless steel, possessing sufficient structural strength and stability. This effectively prevents displacement due to vibration during operation, ensuring detection accuracy. The rotating unit, installed in the central area of ​​the base 1, functions to rotate the clamped paper cup at a uniform speed. This allows the inspection machine 2 to perform comprehensive inspection of the entire circumference and all sides of the paper cup, avoiding blind spots and adapting to the inspection needs of square and other irregularly shaped paper cups with multiple sides and irregular contours.

[0019] The first clamping unit is fixedly mounted on the rotating unit and rotates synchronously with it. The second clamping unit is mounted above the base 1 and is positioned vertically opposite to the first clamping unit. The two units work together to firmly clamp the paper cup from the bottom and top, respectively, achieving precise positioning and preventing displacement or shaking during rotation and inspection, thus ensuring the accuracy of the dimensional inspection data. The inspection machine 2 is mounted above the base 1, located to one side of the second clamping unit. Its inspection probe is aligned with the clamped and positioned paper cup, allowing for real-time acquisition of the cup's dimensional data and preliminary data comparison and feedback.

[0020] The lower end of the base 1 is fixedly connected to multiple support legs 3. In this embodiment, four support legs 3 are preferably provided, and the four support legs 3 are distributed in a rectangular array at the four corners of the base 1. The support legs 3 are made of the same stainless steel as the base 1, and anti-slip rubber pads are provided at their lower ends. The anti-slip rubber pads can increase the friction between the support legs 3 and the ground, further improving the stability of the device, and at the same time, can alleviate the vibration generated during the operation of the device, reducing the impact of vibration on the detection accuracy. The rectangular array of support legs 3 can evenly distribute the weight of the base 1 and the components above it, avoiding excessive local stress on the base 1 that could lead to deformation, and extending the service life of the device.

[0021] The rotating unit includes a rotating ring 4 mounted on the base 1. The rotating ring 4 is connected to the base 1 via a bearing, allowing the rotating ring 4 to rotate flexibly around its own axis without noticeable jamming or deviation during rotation. In this embodiment, the rotating ring 4 can be driven by a stepper motor, which is fixedly installed inside the base 1. Its output shaft meshes with the rotating ring 4 through a gear set, allowing precise control of the rotation speed and angle of the rotating ring 4. This adapts to the detection needs of paper cups of different sizes and shapes. For example, when detecting a square paper cup, the rotating ring 4 can be controlled to rotate 90° each time, ensuring that the detection machine 2 can accurately detect the four sides of the paper cup. When detecting a round paper cup, the rotating ring 4 can be controlled to rotate continuously at a uniform speed, achieving comprehensive circumferential detection.

[0022] The first clamping unit includes a first connecting plate 5, which is fixedly connected to the rotating plate via a first connecting rod 6 to ensure that the first clamping unit and the rotating unit move synchronously. A first clamping cylinder 7 is fixedly connected to the first connecting plate 5. The first clamping cylinder 7 is a small piston cylinder with a compact structure and rapid response. Its output end faces the center of the rotating plate and is fixedly connected to the first moving plate 8, which can drive the first moving plate 8 to move in a direction close to or away from the center of the rotating plate.

[0023] The first movable plate 8 is provided with multiple sets of slots 9 arranged in an array, which diffuse outwards circumferentially. The number of slots 9 is set according to the shape and size of common irregularly shaped paper cups. In this embodiment, 4-6 sets are preferably provided. The cross-section of the slots 9 is T-shaped. The rotating plate is provided with through slots 10 corresponding to the slots 9 one by one. The size of the through slots 10 matches the slots 9 to ensure that the first clamping plate 11 can pass smoothly through the through slots 10 and be inserted into the slots 9. The first clamping plate 11 is inserted into the slot 9. The first clamping plate 11 is an elastic plate with a certain elastic deformation capability, which can adapt to the bottom clamping requirements of paper cups of different shapes and sizes, avoid damage to the bottom of the paper cup due to excessive clamping force, and can closely fit the irregular contour of the bottom of the paper cup to improve clamping stability.

[0024] The first clamping plate 11 is provided with a clamping curved surface 12. The curvature of the clamping curved surface 12 can be adapted to the contour of the bottom of common paper cups, and the elasticity of the elastic plate allows the clamping curved surface 12 to adaptively conform to the bottom edge of irregularly shaped paper cups such as round and square cups, achieving multi-point uniform clamping of the bottom of the paper cup and preventing the bottom of the paper cup from shifting. In addition, the first clamping plate 11 and the slot 9 are detachably connected, and the first clamping plate 11 of corresponding length and corresponding clamping curved surface 12 can be replaced according to paper cups of different sizes and shapes, further improving the versatility of the device.

[0025] The second clamping unit includes a second connecting plate 13, which is fixedly connected to the base 1 via a second connecting rod 14. The second connecting rod 14 is an adjustable telescopic rod, which can adjust the height of the second connecting plate 13 according to the different heights of the paper cups, thereby adjusting the clamping height of the second clamping unit to accommodate round and irregularly shaped paper cups of different heights. A second clamping cylinder 15 is fixedly connected to the second connecting plate 13. The second clamping cylinder 15 is the same model as the first clamping cylinder 7, and has a rapid response and controllable clamping force. Its output end faces the center of the base 1 and is fixedly connected to the first adjusting block 16, which can drive the first adjusting block 16 to move in the vertical direction.

[0026] The lower end of the second connecting plate 13 is connected to a connecting ring 18 via a third connecting rod 17. The connecting ring 18 has a ring structure, and its axis coincides with the axis of the rotating ring 4. Multiple second adjusting blocks 19 arranged in a circular array are inserted inside the connecting ring 18. The number of second adjusting blocks 19 is the same as the number of slots 9 on the first moving plate 8. In this embodiment, 4-6 sets are preferably provided. The second adjusting blocks 19 can move along the radial direction of the connecting ring 18. The first adjusting block 16 is provided with a first inclined surface 20, which faces the second adjusting block 19 and forms an angle of 30-45° with the horizontal plane. The second adjusting block 19 is provided with a second inclined surface 21 that fits against the first inclined surface 20. The second inclined surface 21 is provided with a snap-fit ​​protrusion 22. The first inclined surface 20 is provided with a first snap-fit ​​groove 23 that matches the snap-fit ​​protrusion 22. The snap-fit ​​protrusion 22 and the first snap-fit ​​groove 23 cooperate with each other to ensure the transmission stability between the first adjusting block 16 and the second adjusting block 19, avoid relative sliding between the two, and ensure the accurate transmission of clamping force.

[0027] When the second clamping cylinder 15 drives the first adjusting block 16 to move downward, the first inclined surface 20 and the second inclined surface 21 press against each other, pushing the second adjusting block 19 to move towards the center along the radial direction of the connecting ring 18, thereby clamping the upper part of the paper cup; when the second clamping cylinder 15 drives the first adjusting block 16 to move upward, the pressing force between the first inclined surface 20 and the second inclined surface 21 disappears, and the second adjusting block 19 moves outward along the radial direction of the connecting ring 18 under its own weight or the action of the return spring, releasing the clamping of the paper cup. The operation is convenient and efficient.

[0028] The second adjusting block 19 is equipped with a fine-tuning clamping unit, which includes a fine-tuning plate 24. A first annular protrusion 25 is fixedly connected to the fine-tuning plate 24. The second adjusting block 19 is equipped with a first annular locking groove 26 that matches the first annular protrusion 25. The first annular protrusion 25 is magnetically connected to the first annular locking groove 26, allowing the fine-tuning plate 24 and the second adjusting block 19 to rotate flexibly and maintain a stable connection. A flexible clamping pad is provided on the inner side of the fine-tuning plate 24 to prevent excessive clamping force from damaging the upper sidewall of the paper cup. It also closely conforms to the irregular contour of the upper part of the paper cup, achieving precise fine-tuning clamping of the upper part of the paper cup, further improving the positioning accuracy of the paper cup and ensuring that the paper cup does not wobble or shift during the testing process. Furthermore, the fine-tuning plate 24 can be quickly disassembled and replaced using magnetic adsorption to adapt to the upper clamping needs of paper cups of different shapes and sizes.

[0029] The inspection machine 2 is fixedly connected to the second connecting rod 14, specifically by means of clamps or bolts. The installation height of the inspection machine 2 can be adjusted synchronously with the length of the second connecting rod 14, ensuring that the inspection probe of the inspection machine 2 can accurately align with the inspection area of ​​the clamped and positioned paper cup. In this embodiment, the inspection machine 2 is a vision inspection machine 2, which features high-speed acquisition and accurate recognition. It can collect data such as the height, diameter, sidewall thickness, and irregular contour dimensions of the paper cup in real time and compare them with preset standard dimensions to quickly determine whether the paper cup size is qualified. It has high inspection efficiency and high accuracy, and is suitable for large-scale production needs.

[0030] When this device is in operation, firstly, according to the size and shape of the irregularly shaped paper cup to be tested, the first clamping plate 11 and the fine-tuning plate 24 of the corresponding specifications are replaced, and the clamping height of the second clamping unit is determined by adjusting the length of the second connecting rod 14. Then, the paper cup to be tested is placed on the rotating plate, and the first clamping cylinder 7 is activated. The first clamping cylinder 7 drives the first moving plate 8 to move, causing the first clamping plate 11 to pass through the through groove 10 and move closer to the bottom of the paper cup. Using the elasticity of the first clamping plate 11 and the clamping curved surface 12, the bottom of the paper cup is clamped evenly at multiple points. Next, the second clamping cylinder 15 is activated, and the second clamping cylinder 15 drives the first adjusting block 16 to move downward. Through the compression of the first inclined surface 20 and the second inclined surface 21, the second adjusting block 19 is pushed closer to the upper part of the paper cup. Using the flexible clamping pad on the fine-tuning plate 24, the upper part of the paper cup is precisely fine-tuned and clamped, completing the positioning and clamping of the paper cup.

[0031] After positioning and clamping are completed, the rotating unit is activated, driving the rotating ring 4, the first clamping unit, the paper cup, and the second clamping unit to rotate synchronously. Simultaneously, the inspection machine 2 is activated. The inspection probe of the inspection machine 2 collects dimensional data from various parts of the paper cup in real time, compares and provides feedback to determine if the paper cup's dimensions are acceptable. After inspection, the rotating unit stops rotating, the first clamping cylinder 7 and the second clamping cylinder 15 reset, releasing the paper cup and removing it, completing a single inspection cycle. The entire inspection process is highly automated, easy to operate, and can continuously inspect multiple paper cups, adapting to the needs of large-scale production.

[0032] Through the coordinated operation of the first and second clamping units, combined with a detachable and adjustable structural design, the device can adapt to the positioning and clamping needs of various irregularly shaped paper cups, such as round and square cups, as well as paper cups of different sizes. This solves the problem of poor versatility of existing testing equipment, eliminating the need for dedicated testing equipment for paper cups of different shapes, significantly reducing production input costs and production space occupation. The rotating unit drives the paper cup to rotate at a uniform speed, which, together with the comprehensive testing of the testing machine 2, avoids blind spots and improves the accuracy and comprehensiveness of dimensional testing, adapting to the dimensional testing needs of new irregularly shaped paper cups with high strength and high sealing performance. The device has a compact overall structure, is easy to operate, and has a high degree of automation, which can improve the flexibility and efficiency of the testing process and meet the current large-scale and diversified processing needs of irregularly shaped paper cups. At the same time, the first clamping plate 11 uses an elastic plate and a fine-tuning plate 24 to set a flexible clamping pad, which can prevent damage to the paper cup during clamping, protect the high strength and high sealing performance of the paper cup, and reduce product loss.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
