[0025] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model will be further described.

[0026] As Figures 1-4 shown, an iron chip separator for screw processing includes:

[0027] A frame 3, on which bottom blocks 331 are symmetrically arranged, and extension columns 332 are symmetrically arranged on the bottom blocks 331, and a spring 333 is arranged at one end of the extension column 332;

[0028] A separation plate 2, which is arranged in the frame 3 and cooperates with the spring 333;

[0029] A hopper 1, which is arranged on one side of the frame 3, and a feeding plate 12 with an outlet facing the separation plate 2 is arranged in the hopper 1;

[0030] A transmission unit 7, which is arranged at the bottom of the frame 3, and the transmission unit 7 includes a cam 73 that cooperates with the separation plate 2, and the cam 73 rotates to push against the separation plate 2 to vibrate on the spring 333.

[0031] Specifically, a four-corner underframe 6 is arranged at the bottom of the frame 3 to improve the stability of the device after operation. The screws are introduced into the hopper 1, and the screws slide onto the separation plate 2 through the inclined part of the feeding plate 12. Then, the two cams 73 are driven to run synchronously. By continuously contacting the separation plate 2 with the two cams 73, the separation plate 2 is elastically pulled back by the spring 333, so that the iron chips in the screws are quickly separated, further improving the cleaning effect on the screws.

[0032] As a further embodiment provided by the present utility model, cleaning cylinders 11 are symmetrically and rotatably connected to the feeding plate 12, and brushes are arranged in a circumferential array on the cleaning cylinders 11. The cleaning cylinders 11 cooperate with the transmission unit 7, and the two cleaning cylinders 11 rotate simultaneously in the hopper 1, so that the brushes fully contact the thread grooves of the screws, and the iron chips in the thread grooves are separated, further improving the cleaning effect on the screws.

[0033] As a further embodiment provided by the present utility model, the transmission unit 7 further includes a motor 71, a rotating shaft 77, and a second pulley 78 disposed on the rotating shaft 77. The rotating shaft 77 is composed of two shafts respectively cooperating with the two cleaning cylinders 11. The output end of the motor 71 is provided with a first pulley 711. A synchronous belt 79 is disposed between the first pulley 711 and the two second pulleys 78. The motor 71 is fixed to the bottom of the frame 3, and the model of the motor 71 is: MHMF042L1U2M2. The motor 71 is fixed to the bottom of the frame 3 through a bracket 710. The motor 71 serves as a power source, so that the first pulley 711 drives the second pulley 78 to rotate through the synchronous belt 79, that is, the two rotating shafts 77 drive the cleaning cylinders 11 to rotate synchronously.

[0034] As a further embodiment provided by the present utility model, a first bevel gear 712 cooperating with the frame 3 is disposed at the center of the axis of the first pulley 711. Rotating rods 72 are symmetrically and rotatably connected inside the frame 3. Second bevel gears 74 meshing with the first bevel gear 712 are disposed at the ends of the rotating rods 72. Cams 73 are disposed on the rotating rods 72. Bases 75 supporting the rotating rods 72 are symmetrically disposed on the frame 3. By using the first bevel gear 712 to mesh with the two second bevel gears 74 to rotate, and the rotation directions of the two second bevel gears 74 are different, and the two cams 73 are mirror-symmetrically disposed on the rotating rods 72 respectively, so that when one cam 73 contacts the separation plate 2, the other cam 73 will rotate and collide with the separation plate 2, causing the separation plate 2 to vibrate, further improving the separation effect of the screws and iron filings, and also causing the separation plate 2 to vibrate frequently to accelerate the conveying efficiency of the screws.

[0035] As a further embodiment provided by the present utility model, separation holes 21 are formed in the separation plate 2, and a debris chamber 34 is formed inside the frame 3 directly below the separation holes 21. When the separation plate 2 vibrates under the action of the spring 333, the iron filings in the screws will fall from the separation holes 21 into the debris chamber 34, facilitating the subsequent cleaning of the iron filings.

[0036] As a further embodiment provided by the present utility model, a sliding groove 36 is formed in the frame 3. One of the bottom blocks 331 slides inside the sliding groove 36. Cylinders 51 are symmetrically disposed on the frame 3. Sliders 52 cooperating with the bottom blocks 331 are disposed at the output ends of the cylinders 51. A rubber film 53 is disposed between the sliders 52 and the sliding groove 36. By using the rubber film 53, the iron filings inside the frame 3 are prevented from flowing out of the sliding groove 36. The extension distance of the output rod of the cylinder 51 can be adjusted to push the bottom block 331 to move on the frame 3, thereby adjusting the angle of the separation plate 2, further slowing down or accelerating the sliding speed of the screws.

[0037] As a further embodiment provided by the present utility model, a rotating plate 35 is rotatably arranged on the frame 3, and a material trough 4 is clamped on the rotating plate 35. The material trough 4 is matched with the separation plate 2. The cleaned screws fall along the separation plate 2 into the material trough 4 for storage. At the same time, the rotating plate 35 can be swung to clean the iron filings in the debris chamber 34 of the frame 3.

[0038] Working principle: Pour the screws into the hopper 1. The first pulley 711 at the output end of the motor 71 controls the rotation of the two second pulleys 78 through the synchronous belt 79, so that the two rotating shafts 77 drive the cleaning cylinder 11 to rotate, so as to fully contact the thread grooves of the screws with the brush to remove the iron filings in the thread grooves. Then, both the iron filings and the screws slide down along the inclined part of the blanking plate 12 to the upper part of the separation plate 2. At the same time, the rotation of the first pulley 711 drives the first bevel gear 712 to engage the two second bevel gears 74 to rotate, so that the two cams 73 continuously contact the separation plate 2. Due to the pulling-back effect of the spring 333, the separation plate 2 vibrates, further separating the screw iron filings, so that the iron filings fall from the separation holes 21 into the debris chamber 34, and the cleaned screws fall into the material trough 4, thereby improving the cleaning effect of the screws.

[0039] The above technical solution of the present utility model provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single. The parts not involved in the technical solution of the present application are the same as the prior art or can be implemented by the prior art, and will not be elaborated here.

[0040] The technical solutions in the above embodiments have clearly and completely described the content of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
