DETAILED DESCRIPTION

[0027] In this embodiment, the main body 1 is an existing recycled plastic particle cutting device on the market, which cuts the long plastic parts inserted into the interior through the cooperation of the internal rolling cutter 32, the feed roller 33 and the pressure roller 43. The specific principle is the existing technology, so it will not be described in detail.

[0028] Combination Figure 1 As shown, the motor 21 is electrically connected to an external power source, and the rolling cutter 32 and the feeding roller 33 are rotatably installed in the inner cavity 31 .

[0029] Furthermore, a row of locking screws can be seen on the lower side of the feed roller 33. The operator adjusts the size of the rolling cutter 32 by rotating the locking screws, thereby changing the size of the produced particles.

[0030] Combination Figure 1 As shown, one end of the rolling cutter 32 passes through the inner cavity 31, and a pulley is installed on the rotating shaft of the motor 21 and one end of the rolling cutter 32. The motor 21 and the rolling cutter 32 are connected by using a belt drive at the pulley.

[0031] Furthermore, the sizes of the pulleys at one end of the rotating shaft of the motor 21 and the roller cutter 32 are different, and the pulleys of different sizes maintain a sufficient distance so that the belt between the two can generate sufficient force and transmission can be achieved through the belt.

[0032] Combination Figure 1 , Figure 2As shown, the grooves 34 are symmetrically arranged, and the positions of the grooves 34 and the support rods 41 correspond to each other. A pin is installed at the bottom of the support rod 41, and the frame 4 is rotatably installed in the inner cavity 31 through the pin.

[0033] Furthermore, when the frame 4 is flipped outward through the pin shaft at the bottom, the support rod 41 will lean against the edge of the body 3, and the rotation trajectory of the support rod 41 will coincide with the location of the groove 34, that is, the support rod 41 will fall into the groove 34.

[0034] Combination Figure 3 , Figure 4 As shown, the support rod 41 is symmetrically installed, and the pressing roller 43 is rotatably connected to the connecting seat 42, and the through hole 44 is located at one end close to the bottom of the support rod 41. The slide 45 is set to a bent shape, and one end of the slide 45 is tilted downward. The bend of the slide 45 is set to a smooth arc, and the fixed blocks 5 are installed at intervals.

[0035] Furthermore, the slide 45 is configured to be bent and one end of the slide 45 is tilted downward. This design allows the round rod 82 to move smoothly along the slide 45. At the same time, the slide 45 and the arc block 72 cooperate with each other to limit the round rod 82 in the later stage.

[0036] Combination Figure 3 , Figure 4 As shown, the length of the slide rod 6 is greater than the through hole 44 , a limit block is provided at one end of the slide rod 6 , one end of the spring 61 is connected to the support rod 41 , and the other end of the spring 61 is connected to the slide rod 6 .

[0037] Furthermore, the round block 73 is located on the lower side of the arc block 72. When the arc block 72 is pressed against the slide bar 6 to rotate clockwise around the round block 73, the distance between the arc block 72 and the slide 45 gradually increases. When rotating counterclockwise, the distance decreases, and finally the arc block 72 presses against the slide 45.

[0038] Combination Figure 3 , Figure 4 As shown, the other end of the slide rod 6 faces the square block 71 , a spring 61 is provided on the outer wall of the arc block 72 and connected to the support rod 41 , and the round block 73 is rotatably connected to the fixed block 5 .

[0039] Furthermore, the elastic force of the spring 61 is used to restore the arc block 72 to its initial state, and the elastic force of the spring 61 is used to prevent the arc block 72 from sliding and causing the round rod 82 to disengage.

[0040] Combination Figure 4 , Figure 5 As shown, the anti-slip frame 8 is obliquely installed in the groove 34 , and the inclination of the anti-slip frame 8 is consistent with the rotation trajectory of the frame 4 .

[0041] Furthermore, the oblique angle of the anti-slip frame 8 allows the position of the arc block 72 to be concentric with the rotation trajectory of the frame 4, so that the round rod 82 can move smoothly along the slide 45.

[0042] The working principle of the utility model is:

[0043] When the operator opens the body 3 for adjustment and flips the frame 4 counterclockwise to the outside through the pin shaft at the bottom, the support rod 41 gradually moves toward the inner wall on the other side of the inner cavity 31 during the slow rotation, and finally the support rod 41 will lean against the inner wall of the inner cavity 31, and at the same time the arc block 72, the slide 45 and the fixed block 5 move to the groove 34.

[0044] Since the anti-slip frame 8 is obliquely installed in the groove 34, the inclination degree of the anti-slip frame 8 is consistent with the rotation trajectory of the frame 4. The round rod 82 in the anti-slip frame 8 will first contact the downwardly inclined end of the slide 45. As the frame 4 rotates, the round rod 82 will move along the slide 45 and then contact the bottom of the arc block 72.

[0045] The round rod 82 presses against the arc block 72, allowing it to rotate clockwise based on the pin shaft at the round block 73. As the arc block 72 rotates, the distance between its lower end and the slide 45 becomes larger, and the inner spring 61 deforms and stretches to produce a reverse elastic force. As the round rod 82 passes over the arc block 72, it loses its pushing effect on it. The spring 61 pulls inward to make the arc block 72 rotate counterclockwise, and the distance between the bottom of the arc block 72 and the slide 45 becomes smaller, until it presses against the outer wall of the slide 45 to limit the round rod 82, thereby preventing the frame 4 from overturning under the influence of external force.

[0046] When disassembling, push the slide bar 6 inward along the through hole 44, and the right end of the slide bar 6 abuts against the square block 71 to make the movable block 7 rotate clockwise, so that the distance between the bottom of the arc block 72 and the slide 45 becomes larger, and the round rod 82 is disengaged, and the frame 4 can be closed normally.

[0047] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.

[0048] Although this article uses more terms such as 1, main body; 2, base; 21, motor; 3, body; 31, inner cavity; 32, rolling cutter; 33, feed roller; 34, groove; 4, frame; 41, support rod; 42, connecting seat; 43, press roller; 44, through hole; 45, slide; 5, fixed block; 6, slide rod; 61, spring; 7, movable block; 71, square block; 72, arc block; 73, round block; 8, anti-drop frame; 81, arc rod; 82, round rod, etc., it does not exclude the possibility of using other terms.
