Description

Technical Field

[0001] The utility model relates to the technical field of plastic card screening, and particularly relates to a plastic card screening device. Background Technique

[0002] The plastic card screening equipment, as the core equipment in the plastic card production process, aims to significantly improve the screening efficiency and product quality. However, when facing plastic cards with various shapes, the existing screening equipment indeed faces some challenges in actual operation.

[0003] Firstly, due to the irregular shapes of plastic cards, they often encounter obstacles when passing through the mesh holes of the sieve. When the cards attempt to pass through the sieve, their irregular shapes may cause friction with the edges or hole walls of the sieve, resulting in jamming. This jamming not only hinders the normal passage of the cards but also may cause the sieve to become blocked, thus greatly reducing the screening efficiency and effect.

[0004] In addition, the elastic and viscous properties of plastics also exacerbate the screening difficulties. These properties make the cards prone to sticking to the sieve, increasing the screening difficulty. More seriously, this sticking may also damage the sieve and shorten its service life. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a plastic card screening device, which can effectively solve the problems put forward in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A plastic card screening device includes a support frame, side frames, a feed inlet, a bottom frame, a driving motor, a screening cylinder, a connection cover, and a discharge port. Two side frames are installed at the upper end of the support frame. A first screening cylinder and a second screening cylinder are installed on the side frames. A connection cover is provided at the bottom end of the second screening cylinder. The driving motor is installed on the lowest side end of the side frame through the bottom frame. The output end of the driving motor is connected to the connection cover and drives the screening cylinder to rotate. The discharge port is installed at the lower end of the side frame for discharging materials, and the feed inlet is installed at the highest side end of the side frame;

[0008] A C-shaped ring is provided at the connection section of the first screening cylinder and the second screening cylinder, and a plurality of elastic rings are sleeved outside the C-shaped ring. The plurality of elastic rings form a circular ring to prevent plastic cards from getting stuck in the shell;

[0009] A fastening screw is inserted into the waist hole opened at the end face of each elastic ring and is installed on the C-shaped ring through a fastening nut. The height of the elastic ring is adjusted by adjusting the fastening screw and the fastening nut to make it suitable for plastic cards of different specifications.

[0010] In a further preferred embodiment, the two groups of discharge ports are fixed to the side frame by bolts, and a collection box is provided at the lower end of each discharge port;

[0011] In a further preferred embodiment, the mesh openings of the first screening cylinder and the second screening cylinder increase in size from top to bottom, and the first screening cylinder and the second screening cylinder are inclined in a range of thirty to sixty degrees;

[0012] In a further preferred embodiment, the C-shaped ring is welded at the port of the first screening cylinder or the second screening cylinder, and waist holes are distributed in an annular manner on the C-shaped ring, and the outer end of the C-shaped ring is designed to be arc-shaped;

[0013] In a further preferred embodiment, the cross section of the elastic ring is designed in a "U" shape, the top view of the elastic ring is designed in a "C" shape, the multiple elastic rings are designed in a circular ring shape, and a gap is formed between two adjacent elastic rings, and the gap is used as an extension space for adjusting the height of the elastic ring;

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, the design involves a circular material overturning structure composed of a C-shaped ring and an elastic ring, which is particularly suitable for the operation of a plastic clip passing through the connecting section of a screening cylinder. This structure cleverly utilizes the elastic characteristics of the elastic ring to gently overturn and lift the plastic clip, effectively preventing the clip from getting stuck in the connecting section, and ensuring a smooth and unobstructed screening process.

[0017] Through this climbing and lifting mechanism, the plastic clip can quickly pass through the connection section and smoothly enter the next screening cylinder, significantly reducing the retention time of the material in the connection section, thereby improving the work efficiency of the entire screening process. The design of the C-ring and the elastic ring is ingenious and can flexibly adapt to plastic clips of different shapes and sizes, ensuring the compatibility of the screening device with plastic clips of various specifications.

[0018] In addition, by adjusting the fastening screw and fastening nut, users can easily adjust the height of the elastic ring to adapt to plastic clips of different specifications. This humanized design makes the screening device more versatile and flexible, and can meet different production needs.

[0019] More importantly, adjusting the height of the elastic ring can also accurately control the angle and strength of the plastic clip during the lifting process, further optimizing the screening effect. For example, for larger or heavier plastic clips, the height of the elastic ring can be appropriately increased to enhance the lifting force; while for smaller or lighter plastic clips, the height of the elastic ring can be lowered to reduce potential damage to the material and ensure the smooth progress of the screening process.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0027] like Figures 1 to 5 As shown in the figure, we introduce a plastic clip screening device, the structure of which includes multiple key components, namely, a support frame 1, a side frame 2, a feed port 3, a bottom frame 4, a drive motor 5, a screening cylinder (including a first screening cylinder 6 and a second screening cylinder 7), a connecting cover 8 and a discharge port 9. First, the two side frames 2 are firmly mounted on the upper end of the support frame 1 to ensure the stability of the entire device. Then, the first screening cylinder 6 and the second screening cylinder 7 are mounted on the side frame 2, wherein the bottom end of the second screening cylinder 7 is specially equipped with a connecting cover 8.

[0028] To drive the rotation of the screening cylinder, the driving motor 5 is installed on the lowest point side end of the side frame 2 through the chassis 4, and its output end is closely connected to the connecting cover 8, thus ensuring the smooth rotation of the screening cylinder. To facilitate the discharge of materials, the discharge port 9 is installed at the lower end of the side frame 2, while the feed port 3 is located at the highest point side end of the side frame 2 for easy feeding of materials.

[0029] At the connection section of the first screening cylinder 6 and the second screening cylinder 7, a C-shaped ring 11 is specially designed, and a plurality of elastic rings 12 are sleeved outside it. These elastic rings 12 together form a circular material overflipping structure, effectively preventing the phenomenon of plastic clips getting stuck. It is worth mentioning that a waist hole is opened on the end face of each elastic ring 12, and it is installed on the C-shaped ring 11 by inserting a fastening screw 13 and a fastening nut 14. By adjusting the fastening screw 13 and the fastening nut 14, we can easily adjust the height of the elastic ring 12 to adapt to plastic clips of different specifications.

[0030] In addition, the screen holes of the first screening cylinder 6 and the second screening cylinder 7 are ingeniously designed to increase gradually from top to bottom, ensuring the accuracy of screening. At the same time, the inclination range of the screening cylinder is set from 30 degrees to 60 degrees, which helps the effective sliding of materials. The C-shaped ring 11 is fixed at the port of the screening cylinder by welding, and its outer end is arc-shaped, which is both beautiful and practical.

[0031] The design of the elastic ring 12 is also exquisite. Its cross-section is "U"-shaped, and its top view is "C"-shaped. A plurality of elastic rings 12 are designed in a circular shape, and the gap formed between two adjacent elastic rings 12 provides sufficient extension space for the adjustment of the height of the elastic ring 12. In addition, rubber rings are bonded to the surfaces of the C-shaped ring 11 and the elastic ring 12, increasing their durability and friction. The fastening screw 13 passes through the waist holes of the elastic ring 12 and the C-shaped ring 11, and a fastening nut 14 and an anti-slip gasket are sleeved to ensure the firmness and stability of the connection. Embodiment

[0032] Similar to Embodiment 1, this embodiment also relates to a plastic clip screening device, and its main structure includes a support frame 1, a side frame 2, a feed port 3, a chassis 4, a driving motor 5, a screening cylinder (including a first screening cylinder 6 and a second screening cylinder 7), a connecting cover 8 and a discharge port 9. Its installation and connection methods are the same as those in Embodiment 1 and will not be elaborated here.

[0033] In this embodiment, the two groups of discharge ports 9 are fixed to the side frame 2 by bolts, ensuring the firmness of the connection. At the same time, a collection box 10 is equipped at the lower end of each discharge port 9 to facilitate the collection and sorting of the screened materials. Such a design not only improves work efficiency but also makes the entire screening process more orderly and efficient.

[0034] Screening process: The plastic clips to be screened are put into the equipment through the feed port 3 located at the side end of the highest point of the side frame 2. The plastic clips first enter the first screening cylinder 6. Since the mesh holes of the first screening cylinder 6 are designed to be small, smaller plastic clips or impurities are initially screened out, and as the screening cylinder rotates and tilts, they slide down along the cylinder wall to the discharge port 9 for discharge. The plastic clips that have passed the initial screening enter the second screening cylinder 7. Since the mesh holes of the second screening cylinder 7 are designed to be large, only plastic clips that meet the requirements can continue to slide down through the mesh holes.

[0035] In the connection section between the first screening cylinder 6 and the second screening cylinder 7, the circular material overturning structure composed of the designed C-shaped ring 11 and the elastic ring 12 on it plays a key role. When the plastic clip reaches this position, due to the elasticity of the elastic ring 12, they can gently overturn and lift the plastic clip to prevent the plastic clip from getting stuck in the connection section. After fine screening and overturning and lifting, the plastic clip finally passes through the screen holes of the second screening cylinder 7, slides down to the discharge port 9 at the lower end of the side frame 2, and enters the collection box 10 for collection and sorting.

[0036] When the plastic clip reaches the connection section between the first screening cylinder 6 and the second screening cylinder 7, due to the elasticity of the elastic ring 12, they can gently flip over and lift the plastic clip, so that the plastic clip can smoothly enter the second screening cylinder 7, avoiding the occurrence of the jamming phenomenon. By adjusting the fastening screw 13 and the fastening nut 14, the height of the elastic ring 12 can be easily adjusted to adapt to plastic clips of different specifications. This design ensures the versatility and screening efficiency of the equipment for plastic clips of different specifications.

[0037] The surfaces of the C-shaped ring 11 and the elastic ring 12 are bonded with rubber rings, which not only increases their durability, but also increases the friction between them and the plastic clip, further improving the stability of the overtaking and screening efficiency. Through the design and use of the elastic ring 12, the plastic clip screening equipment effectively solves the jamming problem and improves the screening efficiency and accuracy.

[0038] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the electric fusion connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0039] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
