Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to a vibrating screen feeding device for plastic packaging structures. Background Technology

[0002] In the production process of the plastic packaging industry, the vibrating screen feeding device occupies a key position connecting the upstream and downstream processes. Its performance directly affects the smooth operation of the entire production chain and the product quality. At the beginning of plastic packaging production, it is usually necessary to pre-process different types and forms of plastic raw materials, such as granular and powdered raw materials.

[0003] Currently, traditional vibrating screen feeding devices use a fixed height and angle for feeding, relying on manual operation or simple mechanical transmission to achieve material conveying. The degree of automation is low, making it difficult to meet the efficiency requirements of modern large-scale production. At the same time, due to the differences in the characteristics of raw materials and the layout of vibrating screen equipment in different plastic packaging production scenarios, existing devices cannot flexibly adjust the feeding position and angle, resulting in poor versatility. Frequent equipment replacement not only increases costs but also reduces production continuity.

[0004] To address these issues, we provide a vibrating screen feeding device for plastic packaging structures. Utility Model Content

[0005] The purpose of this utility model is to provide a vibrating screening and feeding device for plastic packaging structures. Through the cooperation of the feeding component and the screening mechanism, it solves the problem that the feeding device in the prior art adopts a fixed height and angle feeding method, relies on manual operation or simple mechanical transmission to realize material conveying, has a low degree of automation, and is difficult to meet the efficiency requirements of modern large-scale production.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a vibrating screening and feeding device for a plastic packaging structure, comprising a processing table, a feeding assembly fixedly connected to one side of the top of the processing table, and a screening mechanism fixedly connected to the other side of the top of the processing table. The feeding assembly includes a support plate, the bottom of which is fixedly connected to the processing table. A toothed plate is fixedly connected to one side of the support plate. A lifting seat is arranged between the support plates. A first motor is fixedly connected to both sides of the inner cavity of the lifting seat. A first gear is fixedly connected to the output end of the first motor, and one side of the first gear meshes with the toothed plate. A connecting frame is fixedly connected to both sides of the top of the lifting seat. A feeding cylinder is movably connected to one side of the connecting frame via a bearing. A housing is fixedly connected to one side of the connecting frame. A second motor is fixedly connected to one side of the inner cavity of the housing. A feeding cylinder is fixedly connected to the output end of the second motor. The second gear is fixedly connected to one side of the feeding cylinder, and the third gear meshes with the second gear on one side. The support plate has a rectangular structure, and its inner side has a groove that matches the toothed plate along its length. The toothed plate is fixed in the groove by bolt connection to ensure the stability of the connection between the toothed plate and the support plate. The first motor drives the meshing transmission between the first gear and the toothed plate to realize the linear motion control of the lifting seat. By controlling the forward and reverse rotation and speed of the first motor, the height position of the feeding cylinder can be accurately adjusted to adapt to the feeding port requirements of screening equipment of different heights, thereby improving the versatility and applicability of the device. By controlling the rotation angle and direction of the second motor, the tilt angle of the feeding cylinder can be precisely adjusted to optimize the material conveying speed and direction, ensuring that the material can smoothly enter the screening mechanism and improve the feeding efficiency and uniformity.

[0008] The present invention is further configured such that the screening mechanism includes a positioning seat, the bottom of which is fixedly connected to the processing table, a driving mechanism fixedly connected to the top of the positioning seat, mounting seats fixedly connected to both sides of the top of the driving mechanism, a spring fixedly connected to the bottom of the inner cavity of the mounting seat, a sliding block fixedly connected to the top of the spring, a first screen plate fixedly connected to the top of the sliding block, and a second screen plate provided on the top of the first screen plate. During the upward vibration of the first and second screen plates, the spring is compressed, storing elastic potential energy. When the force of the driving mechanism causes the first and second screen plates to reach the highest vibration point, the direction of the force changes, and the first and second screen plates begin to move downward, providing a downward restoring force to assist the first and second screen plates in quickly resetting, enabling the first and second screen plates to promptly begin the next vibration cycle. This ensures that the first and second screen plates can continuously and stably perform high-frequency vibration, causing the material to be continuously thrown up and down on the first and second screen plates, fully contacting the screen holes and improving screening efficiency.

[0009] The present invention is further configured such that the driving mechanism includes a housing, the bottom of which is fixedly connected to a positioning seat, a third motor is fixedly connected to one side of the inner cavity of the housing, a rotating rod is fixedly connected to the output end of the third motor, a connecting rod is sleeved on the surface of the rotating rod, the top of the connecting rod penetrates the inner cavity of the housing and extends to the outside of the housing, a movable seat is movably connected to the top of the connecting rod via a rotating shaft, a connecting plate is fixedly connected to the top of the movable seat, and sliding blocks are fixedly connected to both sides of the connecting plate. The third motor drives the rotating rod to rotate, and the rotational motion is converted into up-and-down reciprocating motion through the connecting rod sleeved on the surface of the rotating rod, and transmitted to the movable seat and the connecting plate through the rotating shaft, thereby driving the sliding block, the first screen plate and the second screen plate to vibrate. This transmission method can provide a stable and controllable vibration source, so that the material moves evenly on the first screen plate and the second screen plate, ensuring the effect and accuracy of the vibration screening, and effectively separating particles and impurities of different sizes in plastic packaging materials.

[0010] The present invention is further configured such that positioning posts are fixedly connected to the four corners of the top of the first screen plate, and positioning holes that cooperate with the positioning posts are opened at the four corners of the top of the second screen plate. When it is necessary to replace the screen plate with a different specification to meet different screening requirements, the operator only needs to lift or lower the second screen plate along the direction of the positioning posts to complete the replacement operation of the second screen plate.

[0011] The present invention is further configured such that there are two support plates, which are symmetrically arranged between each other. During the lifting process of the lifting seat, the symmetrical support plates can evenly bear the weight of the lifting seat and the loading component and the force generated by the movement, so as to prevent the lifting seat from tilting or deviating.

[0012] The present invention is further configured such that sliders are fixedly connected to both sides of the lifting seat, and one side of the slider is slidably connected to the support plate. When the first motor drives the first gear to mesh with the gear plate and drive the lifting seat to rise and fall, the slider slides along the track of the support plate, which effectively restricts the movement direction of the lifting seat and prevents it from shaking or lateral displacement during the lifting process.

[0013] The present invention is further configured such that a first screening hole is provided on the top of the first sieve plate, and a second screening hole is provided on the top of the second sieve plate. The first sieve plate and the second sieve plate are provided with screening holes of different specifications, which can realize multi-stage screening of plastic packaging materials. By setting the first screening hole and the second screening hole with different apertures, the screening particle size range can be flexibly adjusted according to actual production needs to meet the screening requirements of various plastic packaging materials.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, through the transmission structure of the first motor, the first gear and the toothed plate, can achieve precise lifting of the lifting seat, thereby flexibly adjusting the height of the feeding cylinder. The second motor drives the second gear to mesh with the third gear, which can control the angle of the feeding cylinder, so that the device can adapt to vibrating screening equipment with different heights and layouts, greatly improving the versatility and feeding flexibility, reducing manual intervention and improving the level of automated production.

[0016] 2. This utility model uses a third motor to drive the rotating rod and connecting rod to move, providing a stable and controllable vibration source for the screening process, ensuring screening effect. The layered arrangement of the first and second screen plates, along with the positioning columns and positioning holes, facilitates the replacement of screen plates of different specifications, meeting the screening needs of various plastic raw materials with different particle sizes, significantly improving screening accuracy and efficiency. The sliding connection between the slider and the support plate enhances the stability of the lifting seat operation, ensuring a smooth and reliable feeding process. Attached Figure Description

[0026] Example 1

[0027] Please see Figure 1-6 This utility model is a vibrating screening and feeding device for a plastic packaging structure, including a processing table 1. A feeding component 2 is fixedly connected to one side of the top of the processing table 1, and a screening mechanism 3 is fixedly connected to the other side of the top of the processing table 1. The feeding component 2 includes a support plate 21, the bottom of which is fixedly connected to the processing table 1. A toothed plate 22 is fixedly connected to one side of the support plate 21. A lifting seat 23 is provided between the support plates 21. A first motor 24 is fixedly connected to both sides of the inner cavity of the lifting seat 23. A first gear 25 is fixedly connected to the output end of the first motor 24. One side of the first gear 25 meshes with the toothed plate 22. A connecting frame 26 is fixedly connected to both sides of the top of the lifting seat 23. A feeding cylinder 27 is movably connected to one side of the connecting frame 26 through a bearing. A housing 28 is fixedly connected to one side of the connecting frame 26. A second motor 29 is fixedly connected to one side of the inner cavity of the housing 28.

[0028] Specifically: The support plate 21 has a rectangular structure, and its inner side is provided with a groove that matches the toothed plate 22 along the length direction.

By controlling the rotation angle and direction of the second motor 29, the tilt angle of the feeding cylinder 27 can be precisely adjusted to optimize the material conveying speed and direction, ensuring that the material can smoothly enter the screening mechanism 3, and improving the feeding efficiency and uniformity.

[0029] Example 2

[0030] Please see Figure 1-6 Based on Embodiment 1, the screening mechanism 3 includes a positioning seat 31. The bottom of the positioning seat 31 is fixedly connected to the processing table 1. A driving mechanism 32 is fixedly connected to the top of the positioning seat 31. Mounting seats 33 are fixedly connected to both sides of the top of the driving mechanism 32. A spring 34 is fixedly connected to the bottom of the inner cavity of the mounting seat 33. A sliding block 35 is fixedly connected to the top of the spring 34. A first screen plate 36 is fixedly connected to the top of the sliding block 35. A second screen plate 37 is provided on the top of the first screen plate 36. The driving mechanism 32 includes a housing 321. The bottom of the housing 321 is fixedly connected to the positioning seat 31. A third motor 322 is fixedly connected to one side of the inner cavity of the housing 321. A rotating rod 323 is fixedly connected to the output end of the third motor 322. A connecting rod 323 is sleeved on the surface of the rotating rod 323. The connecting rod 324 passes through the inner cavity of the housing 321 and extends to the outside of the housing 321. The top of the connecting rod 324 is movably connected to the movable seat 325 via a rotating shaft. The top of the movable seat 325 is fixedly connected to the connecting plate 326. Both sides of the connecting plate 326 are fixedly connected to the sliding block 35. The top four corners of the first sieve plate 36 are fixedly connected to the positioning post 4. The top four corners of the second sieve plate 37 are provided with positioning holes 5 that cooperate with the positioning post 4. There are two support plates 21, which are symmetrically arranged. The lifting seat 23 is fixedly connected to both sides of the slider 6. One side of the slider 6 is slidably connected to the support plate 21. The top of the first sieve plate 36 is provided with a first screening hole, and the top of the second sieve plate 37 is provided with a second screening hole.

[0031] Specifically: During the vibration of the first sieve plate 36 and the second sieve plate 37, the spring 34 is compressed, storing elastic potential energy. When the force of the drive mechanism 32 causes the first sieve plate 36 and the second sieve plate 37 to reach the highest vibration point, the direction of the force changes, and the first sieve plate 36 and the second sieve plate 37 begin to move downwards, providing a downward restoring force to the first sieve plate 36 and the second sieve plate 37, assisting them in quickly resetting and enabling them to promptly begin the next vibration cycle, ensuring the first sieve plate 36 and the second sieve plate 37... The sieve plate 36 and the second sieve plate 37 can continuously and stably vibrate at high frequency, causing the material to be constantly thrown up and down on the first sieve plate 36 and the second sieve plate 37, fully contacting the sieve holes and improving screening efficiency. The third motor 322 drives the rotating rod 323 to rotate, and through the connecting rod 324 sleeved on the surface of the rotating rod 323, the rotational motion is converted into up and down reciprocating motion, which is transmitted to the movable seat 325 and the connecting plate 326 through the rotating shaft, causing the sliding block 35, the first sieve plate 36 and the second sieve plate 37 to vibrate. This transmission method can provide a stable and controllable vibration source. This ensures uniform movement of materials on the first screen plate 36 and the second screen plate 37, guaranteeing the effectiveness and accuracy of vibrating screening. It effectively separates particles and impurities of different sizes from plastic packaging materials. When different screen plates are needed to meet different screening requirements, the operator simply lifts or lowers the second screen plate 37 along the positioning column 4 to complete the replacement operation. During the lifting process of the lifting seat 23, the symmetrical support plates 21 can evenly bear the weight of the lifting seat 23 and the force generated by the movement of the feeding assembly 2, preventing the lifting seat 23 from tilting or... When the first motor 24 drives the first gear 25 to mesh with the toothed plate 22, and drives the lifting seat 23 to rise and fall, the slider 6 slides along the track of the support plate 21, which effectively restricts the movement direction of the lifting seat 23 and prevents it from shaking or lateral displacement during the lifting process. The first screen plate 36 and the second screen plate 37 are provided with screening holes of different specifications, which can realize multi-stage screening of plastic packaging materials. By setting the first screening hole and the second screening hole with different apertures, the screening particle size range can be flexibly adjusted according to actual production needs to meet the screening requirements of various plastic packaging materials.

[0032] The working principle of this utility model is as follows: Before placing the material, the feeding cylinder 27 is in a low position, which makes it easy for the operator to pour the plastic packaging material into the feeding cylinder 27. The first motor 24 is started. The first motor 24 drives the lifting seat 23 to move linearly upward along the support plate 21 through the cooperation of the first gear 25 and the toothed plate 22. The slider 6 slides on the track of the support plate 21, further restricting the movement direction of the lifting seat 23 and preventing it from shaking or lateral displacement during the lifting process, thereby realizing the adjustment of the height of the feeding cylinder 27.

[0033] After the height adjustment is completed, the second motor 29 is started. The second gear 210 and the third gear 211 at the output end of the second motor 29 mesh with each other. The second motor 29 drives the second gear 210 to rotate, which in turn drives the third gear 211 and the feeding cylinder 27 to rotate around the central axis of the bearing, realizing stepless adjustment of the angle of the feeding cylinder 27. The feeding cylinder 27 is adjusted to a suitable tilt angle. Under the action of gravity, the material slides down the inner wall of the feeding cylinder 27, realizing the purpose of tilting the material and ensuring that the material enters the screening mechanism 3.

[0034] After the third motor 322 starts, it drives the rotating rod 323 to rotate. The connecting rod 324 converts the rotational motion of the rotating rod 323 into up-and-down reciprocating motion. The connecting plate 326 is connected to the sliding block 35. Therefore, the up-and-down reciprocating motion of the connecting rod 324 is transmitted to the movable seat 325 and the connecting plate 326 through the rotating shaft, which in turn drives the sliding block 35, the first screen plate 36 and the second screen plate 37 to vibrate. This ensures that the first screen plate 36 and the second screen plate 37 can continuously and stably vibrate at high frequency, so that the material is constantly thrown up and down on the screen plate, making full contact with the screen holes and improving the screening efficiency.

[0035] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
