Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to a plastic particle separation filter device for film blowing machines. Background Art

[0002] In the film blowing machine production process, the quality and purity of plastic particles are crucial to product quality and production efficiency; therefore, devices for filtering plastic particles are often used to ensure the stability of film blowing machine production and product quality.

[0003] For example, a particle filtering device for a film blowing machine disclosed in Chinese patent application publication number CN118906299A, the existing device allows the electric push rod to move up and down with the first filter frame, the first filter frame can block larger plastic particles to prevent them from continuing to fall, while plastic particles smaller than the through holes of the first filter frame can pass smoothly and continue to fall into the body of the film blowing machine. However, in actual application, the existing device cannot perform more detailed separation and filtration of plastic particles because it only performs simple size screening through the first filter frame. Although larger plastic particles are blocked, smaller impurities and unqualified particles may still enter the body of the film blowing machine through the first filter frame, resulting in low purity and utilization of plastic particles, increasing production failures and defective rates. In addition, the existing device lacks an efficient discharging mechanism, and unqualified plastic particles are difficult to be discharged in time, resulting in low production efficiency and product quality. At the same time, due to poor screening effect, the scrap rate is also relatively high, increasing production costs. In addition, the feeding process of the existing device lacks flexibility and accuracy, and cannot be adjusted in real time according to production needs. This makes it difficult to ensure the stability of the film blowing machine's production process and product quality. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Example 1: Please refer to Figure 1-Figure 7 The utility model provides a technical solution: a plastic particle separation and filtering device for a film blowing machine, comprising a film blowing machine body 1 and a fixed frame 2 on the top thereof, a feed hopper 3 is arranged at the top of the fixed frame 2, and a separation and filtering mechanism 4 for separating plastic particles is arranged in the fixed frame 2.

[0028] The separation and filtration mechanism 4 includes a first mounting frame 41 and a second mounting frame 42 arranged in the fixed frame 2, the first mounting frame 41 is located above the second mounting frame 42, and a vibrating elastic sieve plate 43 is arranged in the first mounting frame 41 and the second mounting frame 42. The purity and utilization rate of the plastic particles are improved, and production failures and defective rates are reduced.

[0029] Furthermore, the separation and filtering mechanism 4 also includes a first motor 44 disposed outside the fixed frame 2, and a connecting rod 45 is drivingly connected to the output shaft of the first motor 44, and a cam 46 capable of contacting the elastic screen plate 43 is disposed outside the connecting rod 45. The first motor 44 drives the connecting rod 45 and the cam 46 to rotate, thereby achieving the vibration of the elastic screen plate 43, thereby completing the screening of the plastic particles.

[0030] Furthermore, two groups of connecting rods 45 are provided, one group of connecting rods 45 is connected to the output shaft of the first motor 44, and the other group of connecting rods 45 is rotatably arranged in the fixed frame 2 and is located below the first installation frame 41. The two groups of elastic screen plates 43 can be vibrated at the same time, thereby realizing secondary screening of the plastic particles, enhancing the screening effect, and improving the purity and consistency of the plastic particles.

[0031] Furthermore, the separation and filtering mechanism 4 further includes a first pulley 47 disposed outside the two groups of connecting rods 45, and a first synchronous belt 48 is provided outside the first pulley 47. The linkage between the first pulley 47 and the first synchronous belt 48 enables the two groups of connecting rods 45 to rotate synchronously, thereby achieving synchronous vibration of the two groups of elastic screen plates 43, ensuring the stability and consistency of the screening process, and improving the screening efficiency and accuracy.

[0032] Furthermore, a discharging mechanism 5 for guiding out the separated plastic particles is provided in the fixed frame 2. The discharging mechanism 5 includes a mounting frame 51 provided at the top of the fixed frame 2 and a second conveying roller 54 rotating in the fixed frame 2. A second motor 52 is provided at the top of the mounting frame 51. A first conveying roller 53 is connected to the output shaft of the second motor 52. A second pulley 55 is provided outside the first conveying roller 53 and the second conveying roller 54. A second synchronous belt 56 is connected to the second pulley 55. The design of the discharging mechanism 5 enables unqualified plastic particles to be guided out in time, avoiding mixing with qualified particles. The production efficiency and product quality are improved, and the production cost and scrap rate are reduced.

[0033] Furthermore, the discharging mechanism 5 also includes a discharging frame 57 disposed outside the fixed frame 2 for discharging the transmitted plastic particles. Two sets of guide frames 58 corresponding to the positions of the first conveying roller 53 and the second conveying roller 54 are disposed in the fixed frame 2, wherein one set of guide frames 58 corresponds to the first conveying roller 53, and the other set of guide frames 58 corresponds to the second conveying roller 54. The design of the discharging frame 57 and the guide frame 58 enables unqualified plastic particles to be smoothly discharged, avoiding blockage and accumulation. This ensures the smoothness and stability of the discharging process, and improves production efficiency and product quality.

[0034] Example 2: Please refer to Figure 8 , and combined with the first embodiment, it is further obtained that the fixed frame 2 is also provided with an auxiliary feeding mechanism 6 for controlling the plastic particles entering the film blowing machine body 1, and the auxiliary feeding mechanism 6 includes a partition plate 61 slidably arranged in the fixed frame 2, and a handle 62 is arranged outside the partition plate 61. Qualified plastic particles can be conveniently put into the film blowing machine body, while avoiding the mixing of unqualified particles. The flexibility and accuracy of the feeding process are improved, and the stability of the film blowing machine production process and the product quality are ensured.

[0035] Furthermore, the auxiliary feeding mechanism 6 also includes a connection frame 63 arranged outside the fixed frame 2, a locking plate 64 for dynamically locking the position of the material separator 61 is slidably arranged in the connection frame 63, and a first spring 65 is arranged between the connection frame 63 and the locking plate 64. The design of the locking plate 64 and the first spring 65 enables the material separator 61 to be firmly locked in the fixed frame 2, avoiding shaking and falling off during the feeding process. The safety and stability of the feeding process are improved, ensuring the smooth progress of the film blowing machine production process.

[0036] In actual operation, when the film blowing machine body 1 is loaded, the process is as follows: First, the plastic particles to be processed are added from the feed hopper 3 to the fixed frame 2. At the same time, the first motor 44 is started to drive the connecting rod 45 to rotate. Under the linkage of the first pulley 47 and the first synchronous belt 48, the other set of connecting rods 45 also rotate synchronously, so that the cam 46 contacts the elastic screen plate 43 in the first installation frame 41 and the second installation frame 42, causing the elastic screen plate 43 to shake, and the plastic particles are separated and filtered. Since two sets of elastic screen plates 43 are provided, the plastic particles will undergo secondary screening.

[0037] During the screening process, plastic particles that do not meet production requirements fall into the guide frame 58 under the action of vibration, and then enter between the first conveyor roller 53 and the second conveyor roller 54. The second motor 52 is started to drive the first conveyor roller 53 to rotate, and unqualified plastic particles are transmitted and discharged and collected through the discharge frame 57. At the same time, the rotation of the first conveyor roller 53 drives the second pulley 55 to rotate, and the second conveyor roller 54 is rotated synchronously through the second synchronous belt 56 to ensure the smooth discharge of plastic particles.

[0038] The plastic particles that meet the production requirements fall on the top of the material separator 61. When it is necessary to put them into the film blowing machine body 1, pull the locking plate 64 to unlock the material separator 61, and then pull the handle 62 to remove the material separator 61, and the plastic particles can fall into the film blowing machine body 1. After the loading is completed, push the material separator 61 back into the fixed frame 2, release the locking plate 64, and the first spring 65 rebounds to make the locking plate 64 re-lock the material separator 61 to prepare for the next loading.

[0039] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
