Technical Field
[0001] This utility model relates to the field of injection molding equipment technology, specifically to an auxiliary component of a screening device for injection molding masterbatch production. Background Technology
[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Rubber and plastic are the raw materials for injection molding. Because the particle size of injection molding raw materials is different, they need to be screened by a screening mechanism before use.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that large-particle injection molding raw materials screened out by existing injection molding masterbatch production screening machines need to be transferred to other crushing mechanisms for secondary crushing, and then transferred back to the screening mechanism for re-screening, the entire screening, crushing, and screening process is lengthy, cumbersome, and inefficient. However, during the screening of masterbatch, the material falls too quickly, and there is a lack of obstruction measures for the masterbatch in the feeding stage, resulting in excessive feeding. This causes the material to directly enter the auger elevator, thus failing to make sufficient contact with the screen, and the screen cannot effectively screen the material. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary component of a screening device for injection molding masterbatch production, comprising an auger elevator, a crusher, a screening machine, a screen, support legs, and a discharge port. The crusher is fixedly connected to the top of the screening machine, and the screening machine is fixedly connected to the bottom left side of the auger elevator. The support legs are fixedly connected to both sides of the bottom of the auger elevator and both sides of the bottom of the screening machine. The discharge port is located at the bottom left side of the screening machine. The screen is disposed inside the screening machine. First support plates are fixedly connected to both sides of the inside of the screening machine. First tension springs are fixedly connected to both sides of the top of the first support plates. The other end of the first tension springs is fixedly connected to the bottom of the screen. A baffle is provided on the right side of the inside of the screening machine, a drive assembly is provided on the left side of the screening machine, and moving assemblies are provided on both sides of the baffle.
[0007] In a preferred embodiment of this invention, the drive assembly includes a support block, a motor, a lead screw, and protrusions. The support blocks are fixedly connected to both sides of the left side of the screening machine, the motor is fixedly connected to the top of the support block, the lead screw is fixedly connected to the output end of the motor, and the protrusions are fixedly connected to both sides of the lead screw surface.

[0008] In a preferred embodiment of this invention, the movable component includes a fixed rod and a first sliding groove. The first sliding groove is located on the right side of the front and the right side of the back of the screening machine. The fixed rod is fixedly connected to the bottom of both sides of the baffle and is slidably connected to the first sliding groove.

[0010] As a preferred embodiment of the present invention, a pin is movably connected to the bottom of the first support plate, the other end of the pin is fixedly connected to the bottom of the screen, and the first tension spring is sleeved on the surface of the pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting a first support plate, a first tension spring, and a baffle, allows the baffle to block the material from falling during screening. Then, the screen drives the first tension spring to stretch and move. After that, the tension spring releases its tension, causing the screen to move and screen the material at the top. This solves the problem that when screening masterbatch, the material falls too fast and there is no blocking measure for the masterbatch in the feeding stage, resulting in excessive feeding and the material directly entering the auger elevator, thus failing to make sufficient contact with the screen and the screen failing to effectively screen the material. This invention has the advantage of effectively screening masterbatch.
[0015] 2. This utility model, by setting up a drive component, when it is necessary to screen materials, starts the motor at the top of the support block, causing the motor to drive the lead screw to rotate, which in turn drives the protrusion to rotate. The protrusion then contacts the screen and moves it, causing the screen to stretch the first tension spring. Finally, when the protrusion disengages from the screen, the first tension spring releases its tension, causing the screen to reset. Thus, the rotation of the protrusion causes the screen to move up and down to complete the screening of materials. By setting up a moving component, after all the materials at the top of the screen have been screened, the fixed rod is moved inside the first chute, causing the fixed rod to drive the baffle to rise, allowing the material blocked by the baffle to enter the auger elevator and then enter the crusher for secondary crushing to complete the pulverization.
[0016] 3. This utility model, by setting up a slider, a second sliding groove, a sliding rod, and a support frame, allows the slider to move through a threaded connection when the lead screw drives the protrusion to rotate. The slider then drives the sliding rod to move inside the second sliding groove. Next, the sliding rod contacts the support frame, causing the support component to move. Finally, the fixing rod drives the fixing frame to move, thus driving the baffle to move. Furthermore, by setting a pin, the stability and safety of the first tension spring are increased, preventing twisting and damage during the tensioning process, thereby extending the service life of the first tension spring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown, the auxiliary components of a screening device for injection molding masterbatch production provided by this utility model include an auger elevator 1, a crusher 2, a screening machine 3, a screen 4, support legs 5, and a discharge port 6. The crusher 2 is fixedly connected to the top of the screening machine 3, and the screening machine 3 is fixedly connected to the bottom left side of the surface of the auger elevator 1.

The two sides inside the screening machine 3 are fixedly connected to the first support plate 7. The two sides of the top of the first support plate 7 are fixedly connected to the first tension spring 8. The other end of the first tension spring 8 is fixedly connected to the bottom of the screen 4. The right side inside the screening machine 3 is provided with a baffle 9, the left side of the screening machine 3 is provided with a drive assembly 10, and the two sides of the baffle 9 are provided with moving assemblies 11.
[0023] refer to Figure 3 The drive assembly 10 includes a support block 101, a motor 102, a lead screw 103, and protrusions 104. The support blocks 101 are fixedly connected to both sides of the left side of the screening machine 3. The motor 102 is fixedly connected to the top of the support block 101. The lead screw 103 is fixedly connected to the output end of the motor 102. The protrusions 104 are fixedly connected to both sides of the surface of the lead screw 103. The surface of the protrusions 104 is movably connected to the bottom of the screen 4.
[0024] As a technical optimization of this utility model, by setting up the drive component 10, when it is necessary to screen materials, the motor 102 on the top of the support block 101 is started, so that the motor 102 drives the lead screw 103 to rotate, and then the lead screw 103 drives the protrusion 104 to rotate. Then, the protrusion 104 contacts the screen 4 and drives it to move. Then, the screen 4 drives the first tension spring 8 to stretch. Finally, when the protrusion 104 disengages from the screen 4, the first tension spring 8 releases the tension and drives the screen 4 to reset. Thus, the rotation of the protrusion 104 drives the screen 4 to move up and down to complete the screening of materials.
[0025] refer to Figure 2 The moving component 11 includes a fixed rod 111 and a first slide 112. The first slide 112 is opened on the right side of the front and the right side of the back of the screening machine 3. The fixed rod 111 is fixedly connected to the bottom of both sides of the baffle 9 and is slidably connected to the first slide 112.
[0026] As a technical optimization of this utility model, by setting the moving component 11, after all the materials at the top of the screen 4 have been screened, the fixed rod 111 is moved inside the first chute 112, and then the fixed rod 111 drives the baffle 9 to rise, so that the material blocked by the baffle 9 enters the auger elevator 1, and then enters the crusher 2 for the second crushing to complete the pulverization.
[0027] refer to Figure 1 The surface of the lead screw 103 is threaded with a slider 12. The screening machine 3 has a second slide groove 13 on both sides. The outer side of the slider 12 is fixedly connected with a slide rod 14. The slide rod 14 is slidably connected to the second slide groove 13. The surface of the fixed rod 111 is fitted with a support frame 15. The other end of the support frame 15 is movably connected to the slide rod 14.
[0028] As a technical optimization of this utility model, by setting up a slider 12, a second slide groove 13, a slide rod 14 and a support frame 15, when the lead screw 103 drives the protrusion 104 to rotate, the lead screw 103 drives the slider 12 to move through the threaded connection. Then, the slider 12 drives the slide rod 14 to move inside the second slide groove 13. After that, the slide rod 14 contacts the support frame 15 and drives the support member to move. Finally, the fixing rod 111 drives the fixing frame to move, and then the fixing rod 111 completes the driving of the baffle 9 to move.
[0029] refer to Figure 3 The bottom of the first support plate 7 is movably connected to a pin 16, and the other end of the pin 16 is fixedly connected to the bottom of the screen 4. The first tension spring 8 is sleeved on the surface of the pin 16.
[0030] As a technical optimization of this utility model, by setting the pin 16, the stability and safety of the first tension spring 8 are increased, preventing the first tension spring 8 from twisting and being damaged during the tensioning process, thereby extending the service life of the first tension spring 8.
[0031] refer to Figure 3 A second tension spring 17 is fixedly connected to the bottom of the baffle 9, and the other end of the second tension spring 17 is fixedly connected to the top of the first support plate 7.
[0032] As a technical optimization of this utility model, by setting a second tension spring 17, when the fixed frame moves the baffle 9 through the fixed rod 111, the baffle 9 drives the second tension spring 17 to be pulled up, and then the support frame 15 moves away from the fixed rod 111. After that, the tension is released by the second tension spring 17 to drive the baffle 9 to reset and block.
[0033] refer to Figure 1 The screening machine 3 has a second support plate 18 fixedly connected to both sides, and the support frame 15 is movably connected to the second support plate 18.
[0034] As a technical optimization of this utility model, by setting a second support plate 18, when the support frame 15 is separated from the contact with the fixing member, the second support plate 18 contacts the support frame 15, thereby preventing the fixing rod 111 from being unable to contact the support frame 15 during use.
[0035] The working principle and usage process of this utility model are as follows: During use, the auger elevator 1 carries the material into the crusher 2, where it finally falls into the screening box. The baffle 9 then blocks the material from being screened. Next, the motor 102 on top of the support block 101 is activated, causing the lead screw 103 to rotate. The lead screw 103 then rotates the protrusion 104, causing it to contact and move the screen 4. The screen 4 then stretches the first tension spring 8. Finally, when the protrusion 104 contacts the screen 4… After disengagement, the first tension spring 8 releases its tension, causing the screen 4 to reset. This causes the rotation of the protrusion 104 to move the screen 4 up and down, thus completing the screening of the material. At the same time, when the lead screw 103 drives the protrusion 104 to rotate, the lead screw 103 drives the slider 12 to move through the threaded connection. Then, the slider 12 drives the slide rod 14 to move inside the second slide groove 13. After that, the slide rod 14 contacts the support frame 15, driving the fixed rod 111 to move. Then, the fixed rod 111 drives the baffle 9 to move, completing the opening of the baffle 9. This has the advantage of effectively screening the masterbatch.
[0036] In summary, the auxiliary component of this screening device for injection molding masterbatch production, through the arrangement of a first support plate 7, a first tension spring 8, and a baffle 9, allows the baffle 9 to block the material from falling during screening. Then, the screen 4 drives the first tension spring 8 to stretch and move. Afterward, the first tension spring 8 releases its tension, causing the screen 4 to move and screen the material at the top. This solves the problem that during masterbatch screening, the material falls too quickly, and the lack of obstruction measures in the feeding stage leads to excessive feeding, causing the material to directly enter the auger elevator and thus fail to make sufficient contact with the screen, preventing the screen from effectively screening the material.
