Since the screen aperture size cannot be dynamically adjusted according to the particle size requirements of different materials, the screen components need to be repeatedly disassembled and replaced when processing diverse raw materials, which reduces production efficiency and increases equipment maintenance costs.

[0006] 2. Existing pellet mills cannot adjust the feeding amount in a timely and convenient manner during the feeding process. This leads to material accumulation or insufficient feeding during the production process, requiring repeated manual intervention and adjustment, which seriously affects the continuity of production and processing efficiency, and fails to meet the usage requirements. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a granulator screen adjustment frame, which solves the problem that most existing screens use fixed aperture screens. Because they cannot dynamically adjust the screen aperture size according to the particle size requirements of different materials, the screen components need to be repeatedly disassembled and replaced when processing diverse raw materials. Furthermore, the feeding amount cannot be adjusted in a timely and convenient manner, which also leads to the problem that material accumulation or insufficient feeding is likely to occur during the production process, requiring repeated manual intervention and adjustment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a granulator screen adjustment frame, comprising a base, a support frame at the top of the base, a motor at one side of the top of the support frame, a main gear on the output shaft of the motor, a driven gear meshing with the outer edge of the main gear, a connecting shaft at the bottom of the driven gear, a turntable at the bottom of the connecting shaft, an adjustment hole at the top of the turntable, a material cylinder at the top of the adjustment hole on the turntable, a discharge port at the bottom of the material cylinder, a granulator body at one side of the bottom of the turntable, a discharge port at the bottom of one side of the granulator body, and an adjustment component inside the discharge port.

[0009] In a preferred embodiment of this utility model, the main gear is fixedly mounted on the output shaft of the motor, and the driven gear is fixedly mounted on the connecting shaft, with the outer edges of the main gear and the driven gear meshing with each other.

[0010] As a preferred technical solution of this utility model, the positions of the adjustment holes and the discharge port are correspondingly set with the positions of the pellet mill body, and there are several sets of adjustment holes arranged in a ring array.

[0011] As a preferred technical solution of this utility model, the adjustment component includes an inner screen and a frame. A sliding groove is provided on the inner wall of the frame, a slider is provided inside the sliding groove, an outer screen is provided on the back of the slider, a screw is provided at the bottom of the outer screen, and an adjustment knob is provided at the bottom end of the screw.

[0012] As a preferred embodiment of this utility model, the sieve holes on both the inner and outer sieves are arranged in a rhomboid shape, and the size of the sieve holes on the inner sieve is larger than that on the outer sieve.

[0013] As a preferred technical solution of this utility model, the size of the chute is adapted to the size of the slider, the slider and the outer screen are integrated, and there are two sets of sliders, which are arranged corresponding to each other at the middle of the frame.

[0014] As a preferred technical solution of this utility model, the frame is provided with a threaded hole that matches the size of the screw, the top end of the screw is rotatably connected to the outer screen, and the bottom end of the screw is fixedly connected to the adjustment knob through the threaded hole.

[0015] Compared with the prior art, this utility model provides a granulator screen adjustment frame, which has the following features:

[0016] Beneficial effects:

[0017] 1. This granulator screen adjustment frame, consisting of an inner screen, a chute, an outer screen, a screw, and an adjustment knob, operates by using an inner screen with larger apertures than the outer screen. Rotating the adjustment knob drives the screw to move the outer screen up and down along the chute. When the inner and outer screens move relative to each other, their diamond-shaped apertures create a dynamic overlapping area. By changing their relative positions, the sieve aperture can be continuously adjusted. This design allows operators to precisely control the aperture size without replacing the screens, meeting the sieving needs of materials with different particle sizes. It avoids the need for repeated disassembly and replacement of screen components when processing diverse raw materials, improving production efficiency and reducing equipment maintenance costs.

[0018] 2. This granulator screen adjustment frame, by setting up a motor, main gear, driven gear, turntable, adjustment hole, and discharge port, allows the outer edges of the main gear and driven gear to mesh with each other during feeding. This enables the motor to start and drive the turntable to rotate synchronously. The rotation speed and rotation time of the turntable driven by the motor are then controlled to regulate the time and frequency of the adjustment hole passing through the discharge port, thereby adjusting the feeding quantity of the device. This design allows for timely and convenient adjustment of the feeding quantity during granulator feeding, avoiding material accumulation or insufficient feeding during the production process and meeting usage requirements.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a granulator screen adjustment frame, including a base 1, a support frame 2 on the top of the base 1, a motor 3 on one side of the top of the support frame 2, a main gear 4 on the output shaft of the motor 3, a driven gear 5 meshing with the outer edge of the main gear 4, a connecting shaft 6 at the bottom of the driven gear 5, a turntable 7 at the bottom of the connecting shaft 6, an adjustment hole 8 at the top of the turntable 7, a material cylinder 9 at the top of the turntable 7 above the adjustment hole 8, a discharge port 10 at the bottom of the material cylinder 9, a granulator body 11 on one side of the bottom of the turntable 7, a discharge port 12 at the bottom of one side of the granulator body 11, and an adjustment component 13 inside the discharge port 12; the main gear 4 is fixedly connected to the output shaft of the motor 3, and the driven gear 5 is fixedly connected to the connecting shaft 6, with the outer edges of the main gear 4 and the driven gear 5 meshing with each other;

[0026] Specifically, the motor 3 can be started to drive the turntable 7 to rotate synchronously, thus realizing the transmission of power. At the same time, the gear connection structure used in this utility model is a relatively common connection structure. In actual use, the corresponding gear specifications can be selected as needed.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The positions of the adjusting holes 8 and the discharge port 10 are set to correspond to the positions of the pellet mill body 11. There are several sets of adjusting holes 8, which are arranged in a ring array.

[0028] Specifically, the rotation speed and rotation time of the turntable 7 driven by the motor 3 can be controlled to adjust the time and frequency of the adjustment hole 8 passing through the bottom outlet 10 of the material cylinder 9, thereby adjusting the feeding quantity of the device. In this practical device, the bottom of the material cylinder 9 is in contact with the turntable 7 for rotation, so there will be no problem of material spillage.

[0029] Reference Figure 1 , Figure 3 and Figure 4The adjustment component 13 includes an inner screen 131 and a frame 132. The inner wall of the frame 132 is provided with a groove 133. A slider 134 is provided inside the groove 133. An outer screen 135 is provided on the back of the slider 134. A screw 136 is provided at the bottom of the outer screen 135. An adjustment knob 137 is provided at the bottom of the screw 136. The size of the groove 133 is adapted to the size of the slider 134. The slider 134 and the outer screen 135 are integrated. There are two sets of sliders 134, and the two sets of sliders 134 are arranged corresponding to each other at the middle of the frame 132.

[0030] Specifically, it facilitates the limiting of the slider 134 connected to the outer screen 135 through the slide groove 133, preventing the rotation of the screw 136 from causing the outer screen 135 to rotate synchronously, and at the same time improving the stability of the outer screen 135 during vertical displacement.

[0031] Reference Figure 3 and Figure 4 The screen holes on the inner screen 131 and the outer screen 135 are both diamond-shaped. The size of the screen holes on the inner screen 131 is larger than that on the outer screen 135. The frame 132 has a threaded hole that matches the size of the screw 136. The top end of the screw 136 is rotatably connected to the outer screen 135, and the bottom end of the screw 136 is fixedly connected to the adjusting knob 137 through the threaded hole.

[0032] Specifically, by adjusting the knob 137, the screw 136 can be driven to move the outer screen 135 up and down along the slide groove 133. When the inner and outer screens move relative to each other, their diamond-shaped screen holes will form a dynamic overlapping area. By changing the relative position of the two, the screening aperture can be continuously adjusted.

[0033] It should be noted that (motor 3 and granulator body 11) are well known or can be found by those skilled in the art related to this utility model, and therefore will not be described here.

[0034] The working principle and usage process of this utility model are as follows: When feeding materials, the main gear 4 on the motor 3 meshes with the driven gear 5 on the connecting shaft 6, so that the start of the motor 3 on the support frame 2 can drive the turntable 7 to rotate synchronously. Then, the rotation speed and rotation time of the turntable 7 driven by the motor 3 can be controlled to adjust the time and frequency of the adjustment hole 8 passing through the bottom discharge port 10 of the material cylinder 9, thereby adjusting the feeding quantity of the device.

[0035] In use, the screen hole size on the inner screen 131 is larger than that on the outer screen 135. By rotating the adjustment knob 137 in the adjustment assembly 13, the screw 136 can be driven to move the outer screen 135 connected to the slider 134 up and down along the slide groove 133 on the frame 132. When the inner and outer screens move relative to each other, their diamond-shaped screen holes will form a dynamic overlapping area. By changing the relative position of the two, the screening aperture can be continuously adjusted.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
