Description

Technical Field

[0001] The utility model belongs to the technical field of separating bottle cap machines, and particularly relates to an automatic plastic bottle cap separating machine. Background Technique

[0002] Recycling plastic bottles can reduce environmental pollution. Recycling plastic bottles can not only reduce the garbage scattered in nature, but also effectively save costs. When recycling, a separating bottle cap machine is used to unscrew and separate the bottle caps. Since the materials are different, the treatment methods are different during recycling, and the bottle body and the bottle cap are treated separately.

[0003] Chinese Patent Application No. 202320583527.6 discloses a plastic bottle cap separating machine. This patent can limit plastic bottles of different sizes. The rotation of the motor drives the rubber friction wheel to contact the bottle cap, so as to drive the bottle cap to rotate and realize the separation work. There is no need for manual rotation, which can effectively improve the separation efficiency. However, during the separation process, both the rubber friction wheel and the bottle cap are circular structures, and the contact part between the rubber friction wheel and the bottle cap is less, resulting in less friction between the rubber friction wheel and the bottle cap. When the rotating rubber friction wheel contacts the bottle cap, it is easy to slip, affecting the speed of unscrewing and separating the bottle cap, and reducing the problem of the progress of the automatic bottle cap separating machine in separating the bottle cap. For this reason, we propose an automatic plastic bottle cap separating machine. Content of the Utility Model

The end of the bottle body 102 is thread - connected with a bottle - cap body 101. A separating mechanism for separating the bottle cap is arranged at the top of one side of the fixed seat 100. The separating mechanism includes a vertical plate 200 and a conveyor belt 206. The conveyor belt 206 can drive the rubber belt 203 to move. Two groups of first bearings 204 are embedded and installed inside the vertical plate 200. The first bearings 204 facilitate the rotation of the driving shaft 213 and the driven shaft 205. Inside the first bearings 204 are arranged the driven shaft 205 and the driving shaft 213. Fixedly sleeved on the outer part of one end of the driving shaft 213 and the driven shaft 205 are rolling cylinders 209. The conveyor belt 206 is sleeved outside the two rolling cylinders 209. Distributed outside the conveyor belt 206 and along the length direction of the conveyor belt 206 are rubber belts 203. When the rubber belts 203 rotate and move, they can make the bottle - cap body 101 rotate through the frictional force with the bottle - cap body 101. Two groups of extension plates are fixedly arranged on one side of the vertical plate 200. A hydraulic rod 216 is arranged between the bottom of the extension plate and the fixed seat 100;

[0023] One side of the vertical plate 200 is fixedly provided with a support plate, and a driving motor 202 is fixedly arranged on the support plate. The driving end of the driving motor 202 drives the driving shaft 213 to rotate, and the driving end of the driving motor 202 is fixedly connected to the other end of the driving shaft 213;

[0024] Two sets of adjusting grooves 215 are formed inside the vertical plate 200. A screw rod 208 is arranged inside the adjusting groove 215. An installation bearing 212 is sleeved on the outer wall of the end of the screw rod 208, and a rotating cylinder 201 is sleeved and fixed on the outer wall of the installation bearing 212;

[0025] A fixing ring 211 is fixedly arranged on the outer part of the other end of the screw rod 208. A nut 210 is threadedly connected to the screw rod 208. The screw rod 208 can be fixed by the nut 210 and the fixing ring 211.

[0026] Through the designed separating mechanism of the present utility model, during use, the surface of the conveyor belt 206 bends, causing the surface of the rubber belt 203 to bend and contact the outer wall of the bottle cap body 102 on the bottle body 101, increasing the contact area with the bottle cap body 101, thereby increasing the friction force. The moving conveyor belt 206 and rubber belt 203 cause the bottle cap body 101 to rotate and separate from the bottle body 102, improving the separation effect and separation efficiency of the automatic bottle cap separator on the bottle cap body 101.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, please refer to Figure 1 and Figure 5 , a clamping member for clamping the bottle body 102 is arranged on the fixing seat 100. The clamping member includes an L-shaped frame 304 and an arc-shaped clamping plate 302. A stud 301 is threadedly connected inside the L-shaped frame 304. A connecting bearing 305 is fixedly arranged at the top of the arc-shaped clamping plate 302. The stud 301 can move the arc-shaped clamping plate 302 upward or downward when rotating through the connecting bearing 305. The bottom of the stud 301 extends into the inside of the connecting bearing 305. A limiting plate 300 is fixedly arranged at the top of the arc-shaped clamping plate 302. A through groove for the top of the limiting plate 300 to pass through is formed inside the L-shaped frame 304;

[0029] Friction rubber 306 is fixedly arranged on the inner wall of the arc-shaped clamping plate 302. The friction rubber 306 and the rubber pad 303 can increase the friction force between the outer wall of the bottle body 102, further increasing the firmness of fixing the bottle body 102. A rubber pad 303 is fixedly arranged on the fixing seat 100, and the outer wall of the bottle body 102 contacts the inner walls of the friction rubber 306 and the rubber pad 303.

[0030] Through the designed clamping member, during use, the inner wall of the friction rubber 306 in the arc-shaped clamping plate 302 contacts the outer wall of the bottle body 102 and clamps it, thereby clamping and fixing the placed bottle body 102, increasing the contact area with the bottle body 102 during clamping, and enabling more stable clamping and fixing of the bottle body 102.

[0031] The working principle and usage process of the present utility model:

[0032] When the present utility model is in use, place the bottle body 102 at a suitable position on the inner wall of the rubber pad 303, and then rotate the top of the stud 301 downward, driving the connecting bearing 305 located below to move downward, thereby driving the arc-shaped clamping plate 302 and the friction rubber 306 to move downward accordingly. Then, the inner wall of the friction rubber 306 contacts and clamps the bottle body 102. Then, adjust the distance between the two rotating cylinders 201 according to the diameter of the bottle cap main body 101. First, turn the nut 210 outside the screw rod 208 outward to loosen it, and then move the two screw rods 208 toward or away from each other to a suitable position according to the diameter of the bottle cap main body 101, driving the installation bearing 212 and the rotating cylinder 201 to rotate, and then the distance between the two rotating cylinders 201 can be adjusted. Subsequently, tighten the nut 210. At this time, the vertical plate 200 moves downward under the action of the hydraulic rod 216, thereby driving the conveyor belt 206 and the rubber belt 203 to move downward accordingly. Subsequently, the lower surface of the rubber belt 203 contacts the outer wall of the bottle cap main body 101. At this time, the rubber belt 203 and the conveyor belt 206 start to bend and conform to the shape of the outer wall of the bottle cap main body 101 due to the obstruction of the bottle cap main body 101. Then, the hydraulic rod 216 stops. At this time, start the driving motor 202. The working end of the driving motor 202 drives the driving shaft 213 to rotate, thereby driving the rolling cylinder 209 to rotate, and then driving the conveyor belt 206 and the rubber belt 203 to rotate and move. At this time, the rubber belt 203 can drive the bottle cap main body 101 to rotate, thereby unscrewing the bottle cap main body 101 from the bottle body 102. Finally, the vertical plate 200 rises to its original position under the action of the hydraulic rod 216.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
