[0027] See also Figure 1-Figure 5 As shown, the utility model is an injection molding machine for producing plastic particles, including a body 1, the top of the body 1 is connected to a cylinder 4, the interior of the cylinder 4 is respectively provided with a driving component 2 and a screening component 3, the top of the cylinder 4 is connected to a feed hopper 5, one side of the cylinder 4 is connected to a connecting pipe 6, the top of the body 1 is connected to a connecting bucket 7, the connecting bucket 7 is communicated with the cylinder 4 through the connecting pipe 6, and the front of the cylinder 4 is hinged with a sealing door 8 through a hinge.

[0028] First, the driving component 2 is used to drive the screening component 3 to move upward rapidly, and the screening component 3 is made to oscillate due to the elastic downward ejection effect of the screening component 3. After the screening preparation is completed, the plastic particles are passed through the feed hopper 5 into the cylinder 4. At this time, the plastic particles are screened by the oscillating screening component 3, and the small particle impurities mixed in the plastic particles fall into the bottom of the cylinder 4 through the holes of the screening component 3, and then enter the body 1 through the connecting pipe 6 and the connecting hopper 7 for injection molding. By integrating the screening step with the body 1, the transportation step after screening is reduced, the transportation time is reduced, and the injection molding efficiency is improved. If the small particle impurities screened inside the cylinder 4 need to be removed and cleaned, only the sealing door 8 needs to be opened to clean the inside of the cylinder 4, which is easy to operate.

[0029] The driving component 2 is convenient for driving the screening component 3 to move upward quickly, and the elastic downward pushing action of the screening component 3 makes the screening component 3 oscillate, so that the small particle impurities mixed in the plastic particles entering the cylinder 4 can be screened out, and the connecting pipe 6 and the connecting bucket 7 are convenient for the screened plastic particles to enter the machine body 1, and the plastic particles are conveniently injection-molded through the machine body 1 to form the plastic particles, which is easy to operate. By integrating the screening step with the machine body 1, the transportation step after screening is reduced, the transportation time is reduced, and it is helpful to improve the injection molding efficiency. If the small particle impurities after screening in the cylinder 4 need to be removed and cleaned, it is only necessary to open the sealing door 8 to clean the inside of the cylinder 4, which is easy to operate.

[0030] In one embodiment, for the above-mentioned drive assembly 2, the drive assembly 2 includes two connecting plates 21 and two cams 23. The two connecting plates 21 are both arranged on the inner wall of the cylinder 4. The top ends of the two connecting plates 21 are connected to the drive source 22, and the two cams 23 are respectively arranged on the power output ends of the two drive sources 22.

[0031] First, the two driving sources 22 are used to drive the two cams 23 to rotate rapidly, and then the screening component 3 is quickly pushed up through the protruding position of the cam 23. At the same time, the elastic downward pushing action of the screening component 3 makes the screening component 3 oscillate up and down repeatedly. After the screening preparation is completed, the plastic particles are passed through the feed hopper 5 into the interior of the cylinder 4. At this time, the plastic particles are screened by the oscillating screening component 3, and the small particle impurities mixed in the plastic particles fall into the bottom of the interior of the cylinder 4 through the holes of the screening component 3, and then enter the body 1 through the connecting pipe 6 and the connecting bucket 7 for injection molding. By integrating the screening step with the body 1, the conveying step after screening is reduced, the conveying time is reduced, and the efficiency of injection molding is improved. If the small particle impurities screened inside the cylinder 4 need to be removed and cleaned, only the sealing door 8 needs to be opened to clean the inside of the cylinder 4, which is easy to operate.

[0032] The driving source 22 is convenient for driving the cam 23 to rotate quickly, and the protruding position of the cam 23 pushes the screening component 3 upward, which is convenient for cooperating with the elastic downward pushing effect of the screening component 3 to make the screening component 3 oscillate up and down, so as to facilitate screening out the small particle impurities mixed in the plastic particles entering the cylinder 4, and conveniently allow the screened plastic particles to enter the machine body 1 through the connecting pipe 6 and the connecting bucket 7, and conveniently allow the plastic particles to enter the machine body 1 through the machine body 1 to be injection molded into the plastic particles, which is easy to operate, and by integrating the screening step with the machine body 1, the transportation step after screening is reduced, the transportation time is reduced, and it helps to improve the injection molding efficiency, and if it is necessary to remove and clean the small particle impurities after screening inside the cylinder 4, it is only necessary to open the sealing door 8 to clean the inside of the cylinder 4, which is easy to operate.

[0033] In one embodiment, for the above-mentioned screening assembly 3, the screening assembly 3 includes two sleeves 31, two sliding rods 33, two fixed plates 35 and four oscillating plates 36. The two sleeves 31 are arranged on the inner side of the top end of the cylinder 4, and the inner side of the top end of the two sleeves 31 is connected to a pushing spring 32. The two sliding rods 33 are respectively arranged on the bottom ends of the two pushing springs 32, and the bottom ends of the two sliding rods 33 are connected to a screening mesh 34. The surface of the screening mesh 34 slides in contact with the inner wall of the cylinder 4. The two fixed plates 35 are respectively arranged on the surfaces of the two sliding rods 33, and the four oscillating plates 36 are all arranged on the inner wall of the cylinder 4. The inner wall of the cylinder 4 is connected with a support plate 37, which is convenient for cooperating with the rotation of the cam 23 to drive the screening assembly 3 to oscillate, and then screen the plastic particles entering the cylinder 4 to remove small particle impurities doped in the plastic particles and improve the injection molding effect.

[0034] In one embodiment, for the above-mentioned sliding rods 33, the surfaces of the two sliding rods 33 are respectively in contact with the inner sides of the two sleeves 31, thereby improving the stability of the fixing plate 35 when driving the screening net 34 to move, thereby improving the smoothness of screening.

[0035] In one embodiment, for the above-mentioned fixing plates 35, the surfaces of the two fixing plates 35 are in contact with the inner wall of the cylinder 4, thereby improving the stability of the movement of the sliding rod 33 and preventing it from deviating from the trajectory of up and down movement.

[0036] In one embodiment, for the above-mentioned support plate 37, the inner side of the support plate 37 is in contact with the surfaces of the two slide rods 33, so that the screening net 34 can be driven upward by the cam 23, and then the plastic particles can be oscillated and screened by cooperating with the elastic downward action of the pushing spring 32.

[0037] In summary, with the aid of the above technical solution of the present invention, first, the two driving sources 22 are used to drive the two cams 23 to rotate rapidly, and then the two fixing plates 35 are quickly pushed upward by the protruding positions of the two cams 23. At this time, the two slide bars 33 and the screening net 34 are pushed upward, and the two slide bars 33 will drive the pushing springs 32 to contract when the two slide bars 33 move upward. Then, when the protruding positions of the cams 23 are rotated and moved downward, the two fixing plates 35 will quickly return downward under the elastic pushing action of the pushing springs 32, and then drive the two slide bars 33 and the screening net 34 to return downward, and the bottom end of the screening net 34 will oscillate and contact with the top ends of the four oscillating plates 36, achieving To oscillate and screen the plastic particles, after the screening preparation is ready, the plastic particles are passed into the cylinder 4 through the feed hopper 5. At this time, the plastic particles are screened by the oscillating screening net 34, and the small particle impurities mixed in the plastic particles fall into the bottom of the interior of the cylinder 4 through the screening net 34, and then enter the body 1 through the connecting pipe 6 and the connecting hopper 7 for injection molding. By integrating the screening step with the body 1, the transportation step after screening is reduced, the transportation time is reduced, and it helps to improve the efficiency of injection molding. If it is necessary to remove and clean the small particle impurities after screening inside the cylinder 4, it is only necessary to open the sealing door 8 to clean the inside of the cylinder 4, which is easy to operate.

[0038] Through the above technical solution, the cam 23 is driven to rotate quickly by the operation of the driving source 22, and the fixed plate 35 and the screening net 34 are pushed upward by the protruding position of the cam 23. The elastic downward pushing action of the pushing spring 32 facilitates the reciprocating up and down oscillation of the screening net 34, so that the small particle impurities mixed in the plastic particles entering the cylinder 4 can be screened out, and the screened plastic particles can be conveniently entered into the machine body 1 through the connecting pipe 6 and the connecting bucket 7. The plastic particles are conveniently injection molded through the machine body 1 to form the plastic particles, which is easy to operate. By integrating the screening step with the machine body 1, the transportation step after screening is reduced, the transportation time is reduced, and the injection molding efficiency is improved. If the small particle impurities screened inside the cylinder 4 need to be removed and cleaned, it is only necessary to open the sealing door 8 to clean the inside of the cylinder 4, which is easy to operate.
