Description

Technical Field

[0001] This utility model belongs to the field of plastic testing equipment, and specifically relates to a quality testing device for PVC plastic particles. Background Technology

[0002] Plastics have a wide range of applications, and they are often processed into particle structures for use. For example, rubber-plastic running tracks are made by filling them with plastic particles. Therefore, with the widespread use of plastic particles, related processing and testing institutions for plastic particles have also emerged.

[0003] Existing screening equipment is mostly designed with a single aperture, which cannot achieve gradient classification of particles; moreover, the screening structure lacks elastic buffer and stable guiding mechanism, which easily leads to particle blockage and incomplete screening. At the same time, it is difficult to flexibly adjust according to the specification requirements of different batches of particles, resulting in poor adaptability.

[0004] Therefore, we propose a quality testing device for PVC plastic particles. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quality testing device for PVC plastic particles.

[0006] To achieve the above objectives, this utility model provides a quality inspection device for PVC plastic particles. The device includes a fixed plate, and a detection component is provided on the inner wall of the fixed plate. The detection component includes a motor, and a long rod is fixedly installed on the output shaft of the motor. A cam is fixedly installed on the side of the long rod away from the motor. A roller is provided on the outer wall of the cam, and a round shaft is fixedly installed on the inner wall of the roller.

[0007] As a preferred technical solution of this utility model: the outer wall of the motor is fixedly installed on the inner wall of the fixing plate, the outer wall of the cam rolls with the outer wall of the roller, and the outer wall of the round shaft is fixedly installed on the outer wall of the square box.

[0008] As a preferred technical solution of this utility model: a controller is fixedly installed on the outer wall of the fixed plate, slide rails are fixedly installed on both sides of the inner wall of the fixed plate, a fixed column is slidably connected to the inner wall of the slide rail, a screening box one is provided on the outer wall of the fixed column, an elastic element is provided at the bottom of the screening box one, a screening box three and a screening box two are respectively provided at the bottom of the elastic element, a collection component is provided at the bottom of the screening box three, and an electric valve is fixedly installed on the outer wall of the screening box one.

[0009] As a preferred technical solution of this utility model: the apertures of the screening box 1, screening box 2 and screening box 3 are large, medium and small in sequence; there are two sets of elastic elements; screening box 3 is connected to screening box 2 through one set of elastic elements; screening box 2 is connected to screening box 3 through one set of elastic elements; and the outer wall of screening box 3 is engaged with the inner wall of the square box.

[0010] As a preferred technical solution of this utility model: the collecting component includes a square box, and the inner wall of the square box is provided with an arc-shaped groove.

[0011] As a preferred technical solution of this utility model: a steel ball is engaged with the inner wall of the arc-shaped groove, a spring is fixedly installed on the side of the steel ball away from the arc-shaped groove, a baffle is provided on the outer wall of the spring, and a circular groove is opened on the inner wall of the baffle.

[0012] As a preferred technical solution of this utility model: the outer wall of the spring is fixedly installed with the inner wall of the circular groove, and the spring is made of alloy steel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The equipment achieves dynamic detection drive by linking the controller with components such as motors, cams, and rollers, requiring minimal manual intervention throughout the process and significantly improving the level of automation. It is also equipped with grading sieve boxes of varying aperture sizes, combined with a sliding structure of elastic elements and slide rails-fixed columns, enabling precise screening of PVC plastic particles of different specifications. This effectively distinguishes between unqualified and qualified particles, improving detection efficiency while ensuring screening accuracy and preventing particles of inconsistent specifications from affecting subsequent processing.

[0014] 2. The operation is simple and intuitive. Applying force to the baffle compresses the steel ball and spring, causing the baffle to rotate and open from the inner wall of the square box. No complex tools or cumbersome steps are required, reducing the difficulty of manual operation and improving the convenience of the collection process. Secondly, the baffle's opening and closing is achieved through the cooperation of the steel ball and spring. The flexible and responsive structural design allows for quick switching of the baffle state, ensuring that particles outside the third screening box are collected promptly, preventing particle accumulation or retention. Thirdly, targeted collection of particles outside the third screening box effectively avoids mixing of particles of different sizes, ensuring the accuracy of graded collection and facilitating subsequent separate processing and quality inspection of particles of different sizes. Fourthly, the elasticity of the spring allows the baffle to stably adhere to the inner wall of the square box when not collecting, preventing accidental particle scattering, while reliably opening when collection is needed. This balances the stability and operability of the collection process, further improving the practicality and collection efficiency of the equipment. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 - Figure 5 The device shown is a quality inspection device for PVC plastic particles, including a fixed plate 1. The inner wall of the fixed plate 1 is provided with a detection component 3. The detection component 3 includes a motor 301. The output shaft of the motor 301 is fixedly mounted with a long rod 302. A cam 303 is fixedly mounted on the side of the long rod 302 away from the motor 301. A roller 304 is provided on the outer wall of the cam 303. A round shaft 305 is fixedly mounted on the inner wall of the roller 304.

[0019] This component drives the long rod 302 and cam 303 to rotate via motor 301. The rolling action of cam 303 and roller 304 drives the circular shaft 305 and related components to move, enabling dynamic detection of PVC plastic particles, improving the automation of the detection process, reducing manual intervention, and increasing detection efficiency.

[0020] In a preferred embodiment: the outer wall of the motor 301 is fixedly installed on the inner wall of the fixing plate 1, the outer wall of the cam 303 contacts and rolls with the outer wall of the roller 304, and the outer wall of the round shaft 305 is fixedly installed on the outer wall of the square box 701.

[0021] Clarify the connection relationships between motor 301, cam 303 and roller 304, and round shaft 305 and square box 701 to ensure stable cooperation of each component of the detection assembly 3, guarantee the stability and reliability of equipment operation, and avoid interruption or increased error in the detection process due to loose component connections.

[0022] In a preferred embodiment: a controller 2 is fixedly installed on the outer wall of the fixed plate 1, slide rails 10 are fixedly installed on both sides of the inner wall of the fixed plate 1, a fixed column 9 is slidably connected to the inner wall of the slide rail 10, a screening box 4 is provided on the outer wall of the fixed column 9, an elastic element 11 is provided at the bottom of the screening box 4, a screening box 6 and a screening box 5 are respectively provided at the bottom of the elastic element 11, a collection component 7 is provided at the bottom of the screening box 6, and an electric valve 8 is fixedly installed on the outer wall of the screening box 4.

[0023] With screening boxes 4, 5, and 6 of different aperture sizes, along with elastic element 11 and electric valve 8, PVC plastic particles can be graded and screened. At the same time, the sliding connection between slide rail 10 and fixed column 9 facilitates the installation and adjustment of screening boxes 4, 5, and 6, improving the equipment's adaptability to particles of different specifications and screening effect.

[0024] In a preferred embodiment: the apertures of screening boxes 1, 2, and 3 are large, medium, and small in sequence; there are two sets of elastic elements 11; screening box 3 is connected to screening box 2 through one set of elastic elements 11; screening box 2 is connected to screening box 3 through one set of elastic elements 11; and the outer wall of screening box 3 is engaged with the inner wall of square box 701.

[0025] The size of the sieve box and the connection method are limited to ensure that the particles can pass through the sieve box in sequence according to specifications, so as to achieve accurate classification. In addition, the snap-fit ​​structure between the sieve box 6 and the square box 701 facilitates the collection and processing of particles after sieving, improving the practicality of the equipment.

[0026] In a preferred embodiment: the collecting component 7 includes a square box 701, the inner wall of which is provided with an arc-shaped groove 706.

[0027] The design of the square box 701 and the arc-shaped groove 706 in the collection component 7 provides a stable structural foundation for the subsequent installation of components such as steel balls 705, which facilitates the orderly collection of PVC plastic particles after screening, prevents particles from scattering, and ensures the cleanliness of the collection process.

[0028] In a preferred embodiment: a steel ball 705 is engaged with the inner wall of the arc groove 706, and a spring 704 is fixedly installed on the side of the steel ball 705 away from the arc groove 706. A baffle 702 is provided on the outer wall of the spring 704, and a circular groove 703 is provided on the inner wall of the baffle 702.

[0029] The interlocking action between the arc-shaped groove 706 and the steel ball 705, combined with the functions of the spring 704 and the baffle 702, can buffer and limit the collected particles, preventing them from being damaged or bouncing and scattering during collection, thus improving the stability of collection and the integrity of the particles.

[0030] In a preferred embodiment, the outer wall of the spring 704 is fixedly installed on the inner wall of the circular groove 703, and the spring 704 is made of alloy steel.

[0031] The fixed installation of spring 704 and circular groove 703 ensures the stable working state of spring 704. Moreover, spring 704, made of alloy steel, has high strength and elasticity, which extends the service life of spring 704, reduces equipment maintenance frequency, and lowers operating costs.

[0032] Working principle: When starting the PVC plastic particle quality testing equipment, the overall operating system is first activated by the controller 2 fixed to the outer wall of the fixed plate 1. Then, the motor 301 starts, and its output shaft drives the long rod 302 to rotate. The cam 303 fixed at the end of the long rod 302 away from the motor 301 rotates accordingly. The outer wall of the cam 303 rolls with the outer wall of the roller 304, thereby driving the round shaft 305 fixed to the inner wall of the roller 304 to move, thus driving the relevant components to achieve dynamic detection of PVC plastic particles. Next, the PVC plastic particles to be tested enter the screening box 4. The screening box 4 is slidably connected to the slide rails 10 on both sides of the inner wall of the fixed plate 1 through the fixed column 9 on the outer wall. The two sets of elastic elements 11 at the bottom of the screening box 4 play a role. Since the apertures of the screening box 4, screening box 5, and screening box 6 are large, medium, and small respectively, and screening box 5 is open to the light, the PVC plastic particles are dynamically detected. A set of elastic elements 11 connects to screening box 4, and screening box 6 connects to screening box 5 via another set of elastic elements 11. The particles are first screened by screening box 4 to remove large-sized particles. Qualified particles enter screening box 2 for medium-sized screening, and then qualified particles enter screening box 6 to complete small-aperture screening. The screened particles enter the collection component 7 through the snap-fit ​​structure between the outer wall of screening box 6 and the inner wall of square box 701. The arc groove 706 on the inner wall of square box 701 snaps with steel ball 705. The spring 704 fixed on one side of steel ball 705 works with baffle 702 to collect the particles, preventing particle damage or scattering. Finally, the entire process of PVC plastic particles from dynamic detection, grading and screening to stable collection is completed, improving the degree of automation and detection efficiency, ensuring stable operation of the equipment and particle integrity, while extending component life and reducing maintenance costs.

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 the principles of this 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.
