Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing equipment, in particular to a plastic particle screening device. Background Art

[0002] Currently in the process of plastic processing, the size of plastic particles after plastic cutting varies. In order to ensure the quality and consistency of plastic particles, screening devices are needed to separate the particles that do not meet the standards, thereby improving product quality.

[0003] However, most of the existing plastic particle screening devices use vibration motors to generate vibration force, so that the screen frame and plastic particles move relative to each other, thereby achieving particle screening. Since the vibration force generated by the vibration motor is too large and the speed is fast, some particles that do not meet the preset requirements (broken) are likely to follow the particles that meet the preset requirements (intact) into the collection basket, thereby affecting the screening effect; at the same time, since the high-speed vibration of the vibration motor generates a large vibration force, long-term use is likely to cause equipment damage, and the maintenance cost is high.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The plastic particle screening device according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the plastic particle screening device of the embodiment of the utility model may include a base 1, a support frame 2, a sliding device 3, a screen plate 4 and a lifting device 5.

[0022] The support frame 2 is arranged on the base 1 .

[0023] It should be noted that the height of one side of the support frame 2 close to the sliding device 3 described in this embodiment is higher than the height of the other side, forming an inclined slope, which facilitates the screening of plastic particles.

[0024] The sliding device 3 may include a driving component 31 and a connecting component 32 .

[0025] The driving component 31 is disposed on the base 1 , the connecting component 32 is disposed on the supporting frame 2 , and the connecting component 32 is connected to the driving component 31 .

[0026] It can be understood that the rotation of the driving component 31 will drive the connecting component 32 to rotate and move forward and backward at the same time.

[0027] The sieve plate 4 is slidably disposed on the support frame 2 , and the other side of the sieve plate 4 is connected to the connecting assembly 32 .

[0028] It can be understood that the forward and backward movement of the connecting component 32 drives the screen plate 4 to move forward and backward synchronously, so as to screen the particles in the screen plate 4, so that the broken particles fall fully into the lower layer, and the sliding device 3 can better protect the equipment and reduce equipment damage.

[0029] The lifting device 5 may include a lifting assembly 51 and a baffle 52 .

[0030] The lifting assembly 51 is arranged on one side of the sieve plate 4 , the baffle plate 52 is slidably arranged on the inner wall of the sieve plate 4 , and the baffle plate 52 is connected to the lifting assembly 51 .

[0031] Among them, it can be understood that the lifting and lowering of the baffle 52 can be realized through the lifting component 51, and the screen plate 4 is driven by the sliding device 3 to perform forward and backward screening movements. When the plastic particles in the screen plate 4 are fully screened, the lifting component 51 is started to lift the baffle 52, and the screened complete particles are collected uniformly. By setting the lifting device 5, the particles can be screened and classified more accurately, avoiding some broken particles from being mixed in the complete particle collection basket, greatly improving the screening accuracy and overall work efficiency.

[0032] Specifically, when it is necessary to screen the plastic particles, pour the processed plastic particles into the screen plate 4, and the connection component 32 is driven to rotate by the rotation of the driving component 31, and move back and forth at the same time. The forward and backward movement of the connection component 32 drives the screen plate 4 to move back and forth synchronously, so that the particles in the screen plate 4 can be screened, and the broken particles can fall fully into the lower layer. The sliding device 3 can better protect the equipment and reduce equipment damage.

[0033] When the plastic particles in the sieve plate 4 are fully screened, the lifting assembly 51 is started to lift the baffle 52, and the complete particles that have been screened are collected uniformly. By setting the lifting device 5, the particles can be screened and classified more accurately, avoiding some broken particles from being mixed in the complete particle collection basket, thereby greatly improving the screening accuracy and overall work efficiency.

The rotating shaft 322 passes through the two bearing seats 321 , and the rotating shaft 322 is connected to the driven wheel 313 .

[0039] It can be understood that the rotation of the driven wheel 313 drives the rotating shaft 322 to rotate in the two bearing seats 321 .

[0040] The rotating disk 323 is connected to one end of the rotating shaft 322 . The connecting column 324 is disposed on one side edge of the rotating disk 323 . The connecting rod 325 is connected to the connecting column 324 .

[0046] Among them, it can be understood that when the connecting rod 325 moves forward and backward, it will drive the lower screen plate 42 and the upper screen plate 43 to move forward and backward synchronously, so as to screen the particles in the upper screen plate 43, so that the broken particles can fully fall into the lower screen plate 42, and the particles can be screened and classified more accurately. At the same time, the sliding device 3 can better protect the equipment, and there will be no damage to the equipment due to vibration, so it is more practical.

[0052] It can be understood that when the rotating motor 511 rotates, the threaded rod 512 is driven to rotate, and at the same time, the two sliders 513 are driven to move in opposite directions on the threaded rod 512, driving the connecting rods 514 in groups of two to move, and at the same time driving the baffles 52 to move up and down. After the plastic particles in the sieve plate 4 are fully screened, the lifting component 51 is started to lift the baffles 52, and the complete particles that have been screened are uniformly collected. By setting the lifting device 5, the particles can be screened and classified more accurately, avoiding the mixing of some broken particles in the complete particle collection basket, and greatly improving the screening accuracy and overall work efficiency.
