Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to an automatic feeding crusher. Background Art

[0002] In order to reduce environmental pollution caused by landfill or incineration, etc., and alleviate the shortage of plastic resources, a large number of used plastic infusion bottles and infusion bags generated by medical institutions every day can be collected and recycled through a plastic infusion bottle recycling production line. The recycled infusion bottles first need to be conveyed to a crusher for crushing by a chain conveyor. However, due to the slow crushing speed of the crusher, the infusion bottles may accumulate at the inlet of the crusher. Excessive accumulation may cause backflow from the inlet of the crusher and even fall from both sides of the conveyor. The prior art with the patent number CN219449753U discloses a material receiving hopper anti-overflow device, in which a radar level gauge is fixedly installed in the material receiving hopper. When the materials in the material receiving hopper accumulate, the radar level gauge can send out an audible and visual alarm to guide workers to dredge, thereby enhancing safety. However, when the materials enter from a high place, the radar level gauge may also be accidentally triggered, and manual dredging also requires human resources. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] An automatic feeding crusher of the present utility model has a feeding hopper set with a vertical feeding section and an inclined guiding section. The infusion bottles input by the feeding conveyor can slide down along the inclined guiding section and fall from the vertical feeding section into the feeding port for crushing. When the crushing speed cannot catch up with the feeding speed and causes the infusion bottles to pile up, the infusion bottles will continuously pile up upward along the vertical feeding section. At the same time, it will push the inclined overflow baffle upward, triggering the high-level induction switch to automatically control the feeding conveyor to stop the material transportation until the piled-up material drops and the induction is released, and then automatically restart the feeding conveyor to continue transporting the material. The inclined overflow baffle can also rotate back to its original position under its own gravity without manual adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] As Figures 1 to 5 As shown, the present utility model provides an automatic feeding crusher, which includes a feeding conveyor 100 and a crusher 200. An inlet 210 is provided on the crusher 200, and a feed hopper 220 is connected to the inlet 210. The feed hopper 220 includes a vertical feeding section 221 and an inclined guiding section 222. The vertical feeding section 221 is connected to the inlet 210, and the inclined guiding section 222 is connected to one side of the vertical feeding section 221. The output end of the feeding conveyor 100 is connected to the inlet of the inclined guiding section 222. An inclined overflow baffle 230 is hinged at a position inside the vertical feeding section 221 and above the discharge port of the inclined guiding section 222. A high-level induction switch 240 is provided above one end of the vertical feeding section 221 that is away from the hinged end of the inclined overflow baffle 230. The high-level induction switch 240 is electrically connected to the feeding conveyor 100 and can control the opening or closing of the feeding conveyor 100. The infusion bottles flowing back in the vertical feeding section 221 can upwardly press the inclined overflow baffle 230, so that the inclined overflow baffle 230 turns upward and triggers the high-level induction switch 240. Among them, the feeding conveyor 100 can adopt an existing climbing conveyor, which can upwardly convey the infusion bottles stacked on the ground into the feed hopper 220; the inclined overflow baffle 230 is installed above the discharge port of the inclined guiding section 222 to ensure that the infusion bottles can smoothly enter the vertical feeding section 221; the high-level induction switch 240 can adopt a push-type induction switch, and the switch control is carried out through the contact and pressing of the inclined overflow baffle 230.

[0026] Specifically, a rotating shaft 231 is installed inside the vertical feeding section 221 and above the discharge port of the inclined feeding section 222, and one end of the inclined overflow baffle 230 is rotatably installed on the rotating shaft 231. When the infusion bottles are stacked and the height gradually rises, the inclined overflow baffle 230 will be able to rotate upward around the rotating shaft 231 to press against the high-level induction switch 240 and send a signal to close the feeding conveyor 100; after the infusion bottles are gradually crushed and the height decreases, the inclined overflow baffle 230 automatically rotates downward to reset and releases the pressing on the high-level induction switch 240, and the high-level induction switch 240 will send a signal to turn on the feeding conveyor 100.

[0027] Furthermore, in the present application, the original inclination angle of the inclined overflow baffle 230 can be the same as the angle of the inclined feeding section 222. To facilitate determining its original inclination angle, a limiting plate 223 that can abut against the bottom of the inclined overflow baffle 230 is provided inside the vertical feeding section 221 and below the end of the inclined overflow baffle 230 away from the hinged end to support and limit the inclined overflow baffle 230. Of course, other rotation angle limiting structures can also be provided at the hinged end of the inclined overflow baffle 230. In addition, the inclined overflow baffle 230 can be made of a material with a relatively light mass to ensure that the infusion bottles can smoothly push it upward; at the same time, in order to ensure that the inclined overflow baffle 230 can automatically reset after the stacked infusion bottles drop, a counterweight is provided inside the end of the inclined overflow baffle 230 away from the hinged end, so that the inclined overflow baffle 230 will be able to automatically rotate downward around the rotating shaft 231.

[0028] In another specific embodiment of the present application, a low-level induction switch 250 is provided on the top of the limiting plate 223. The low-level induction switch 250 is electrically connected to the feeding conveyor 100 and can control the opening or closing of the feeding conveyor 100. When the height of the infusion bottles in the vertical feeding section 221 decreases, the inclined overflow baffle 230 can rotate downward to trigger the low-level induction switch 250. Among them, the high-level induction switch 240 can also be a push-type induction switch. Since when the infusion bottles start to drop, the inclined overflow baffle 230 immediately releases the pressing on the high-level induction switch 240, and at this time, a start signal is immediately sent to continue conveying the material, it is still easy to have a stacking situation. Therefore, by adding the low-level induction switch 250, at this time, the height of the stacked infusion bottles needs to be further reduced before the inclined overflow baffle 230 can trigger the low-level induction switch 250 to continue opening the material conveying of the feeding conveyor 100.

[0029] Further, to increase the contact surfaces between the inclined overflow baffle 230 and the high-level sensor switch 240 and the low-level sensor switch 250 to ensure the accuracy of sensing, a trigger bump 232 capable of cooperating with the high-level sensor switch 240 is provided on the upper surface of the inclined overflow baffle 230, and a trigger groove 233 capable of cooperating with the low-level sensor switch 250 is formed on the lower surface of the inclined overflow baffle 230.

[0030] In a specific embodiment of the present application, for automatic control, a control device is further included. The control device includes a central processing unit and a controller that are electrically connected to each other. The high-level sensor switch 240 and the low-level sensor switch 250 are both electrically connected to the central processing unit, and the motor of the feeding conveyor 100 is electrically connected to the controller. The central processing unit can receive and process the switch signals sent by the high-level sensor switch 240 and the low-level sensor switch 250, and the controller can control the opening or closing of the motor of the feeding conveyor 100 according to the processing result of the central processing unit. Among them, the central processing unit and the controller are both prior arts and will not be elaborated in detail in the present application.

[0031] In a specific embodiment of the present application, a crushing chamber 260 is provided inside the crusher 200. The input end of the crushing chamber 260 is connected to the feeding port 210. A crushing knife rod 261 is rotatably installed in the crushing chamber 260. Crushing blades 262 capable of cooperating with the crushing knife rod 261 are provided on both sides of the inner wall of the crushing chamber 260. The crushing knife rod 261 rotates and cooperates with the crushing blades 262 to cut the materials. Further, to ensure complete crushing, a sieve plate 270 is provided inside the crusher 200 at the position of the discharge port of the crushing chamber 260. This crusher 200 can adopt the prior art, and reference can be made to the plastic crusher disclosed in the prior art with the patent number CN219788957U.

[0032] For the automatic feeding crusher of the present utility model, by setting the feeding hopper 220 as a vertical feeding section 221 and an inclined guiding section 222, the infusion bottles input by the feeding conveyor 100 can slide down along the inclined guiding section 222 and fall from the vertical feeding section 221 into the feeding port 210 for crushing. When the crushing speed cannot catch up with the feeding speed and causes the infusion bottles to pile up, the infusion bottles will continuously pile up upward along the vertical feeding section 221, and at the same time, will push the inclined overflow baffle 230 upward, so that the high-level sensor switch 240 is triggered to automatically control the feeding conveyor 100 to stop the material feeding until the piled-up materials drop and the induction is released, and then the feeding conveyor 100 is automatically restarted to continue feeding the materials. The inclined overflow baffle 230 can also rotate back to its original position under its own gravity without manual adjustment.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention shall be covered by the technical solutions of the present invention.
