Description

Technical Field

[0001] The utility model relates to a plastic sheet scrap recovery device, belonging to the technical field of plastic processing. Background Art

[0002] At present, when processing plastic sheets, it is generally necessary to cut and trim the prepared plastic sheets to achieve the required specifications. Among them, the plastic sheet raw materials will produce scraps during processing. In order to reduce processing costs, these scraps are often collected and reused.

[0003] After being crushed by a crusher, plastic sheets often need to be weighed and packaged for subsequent processing and utilization. However, the existing quantitative weighing is often done by manual weighing and packaging after the plastic sheets are crushed into a recycling bin, which is extremely inconvenient and greatly reduces the efficiency of plastic sheet recycling.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a device for recycling plastic sheet scraps, which solves the problem in the prior art that after the plastic sheets are crushed into a recycling box, they need to be manually weighed and packaged, which is extremely inconvenient to operate and greatly reduces the work efficiency of plastic sheet recycling.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a plastic sheet scrap recycling device comprises a box body, wherein a feeding port, a crushing chamber, a quantitative chamber and a recovery chamber are respectively arranged inside the box body from top to bottom, a quantitative cylinder is rotatably connected in the quantitative chamber, a quantitative port is opened at one end of the quantitative cylinder, a feeding port connected to the crushing chamber and a discharge port connected to the recovery chamber are respectively arranged at both ends of the quantitative chamber, a driving source for driving the quantitative cylinder to rotate is arranged on the outside of the box body, wherein an infrared detection source electrically connected to the driving source is also arranged in the quantitative port.

[0007] By adopting the above technical scheme, when the plastic sheet scraps enter the crushing chamber through the feeding port and are crushed by the crushing mechanism, they will pass through the feeding port and the quantitative port in turn, and then enter the inside of the quantitative cylinder. When the scraps accumulated in the quantitative cylinder rise to the point where they block the infrared detection source for at least 3 seconds, the infrared detection source sends an electrical signal to the servo motor to drive the servo motor to start, thereby driving the quantitative cylinder to rotate half a circle to connect the quantitative port with the feeding port, and maintain this state for at least 10 seconds. Under the action of gravity, the crushed scraps in the quantitative cylinder will enter the recovery chamber and be collected by the staff. Since there is no channel connected to the inside on the outer wall of the quantitative cylinder except the quantitative port, the scraps continuously crushed by the crushing mechanism will accumulate at the feeding port under the cover of the outer wall of the quantitative cylinder. When the servo motor drives the quantitative cylinder to continue to rotate half a circle and connect the quantitative port with the feeding port, the scraps accumulated at the feeding port will fall into the quantitative cylinder under the action of gravity, and this cycle will be completed, thereby completing the quantitative weighing operation of the plastic sheet scraps. The operation is convenient, and the work efficiency of plastic sheet recycling is greatly improved.

[0008] The utility model is further configured as follows: a plurality of scrapers are fixed on the inner wall of one side of the box body at the open end of the quantitative cylinder along the circumferential direction, the scrapers have triangular cross sections, the plurality of scrapers are all located in the quantitative cylinder and the tips thereof abut against the inner wall of the quantitative cylinder.

[0009] By adopting the above technical solution, when the metering cylinder rotates, the tip of the scraper can scrape off the impurities attached to the inner wall of the metering cylinder, so that the scraps of the plastic sheet can be poured into the recovery chamber more completely.

[0010] The utility model is further configured as follows: a crushing mechanism is arranged in the crushing chamber, the crushing mechanism comprises two crushing rollers rotatably connected to the inside of the crushing chamber, a crushing chamber is formed between the two crushing rollers, a rotating shaft is fixed inside the crushing rollers, the two rotating shafts both extend outside the box body and are fixed with two mutually meshing gears, a driving motor for driving one of the gears to rotate is arranged on the outer wall of the box body,

[0011] Among them, baffles are obliquely arranged on both sides of the feeding port, a feeding chamber is formed between the bottom ends of the two baffles, the feeding chamber is located directly above the crushing chamber, baffle plates are obliquely arranged on both sides of the bottom of the crushing chamber, and a feeding trough connected with the feeding port is formed between the bottom ends of the two baffle plates.

[0012] By adopting the above technical scheme, the two meshing gears are driven to rotate by the driving motor, thereby driving the crushing roller to rotate, and then crushing the scraps poured into the crushing chamber from the feeding port, wherein, through the guiding effect of the baffle plate, the scraps can slide into the feeding chamber along the inclined baffle slope, and since the feeding chamber is located directly above the crushing chamber, the scraps can smoothly slide between the two crushing rollers, and since baffle plates are also provided on both sides of the bottom of the crushing chamber, through the guiding effect of the baffle plate, after the crushing roller crushes the scraps, the scraps can smoothly pass through the feed trough into the feed port and be collected by the metering cylinder.

[0013] The utility model is further configured as follows: one end of the recovery chamber passes through the box body and a recovery box is slidably connected in the recovery chamber, the top end of which is connected to the feed outlet, slide grooves are provided on both sides of the top end of the recovery box, slide bars for inserting into the slide grooves are provided on both sides of the top end of the recovery chamber, and a handle is provided on the outer wall of the recovery box.

[0014] By adopting the above technical solution and setting up a recycling box, the scraps poured out of the self-metering cylinder will be collected in the recycling box, and the staff can push and pull the handle to drive the recycling box to slide and detach from the recycling cavity, which is easy to operate and more convenient to collect scraps.

[0015] The beneficial effect of the utility model is that when the plastic sheet scraps enter the crushing chamber through the feeding port and are crushed by the crushing mechanism, they will pass through the feeding port and the quantitative port in sequence, and then enter the inside of the quantitative cylinder. When the scraps accumulated in the quantitative cylinder rise to the point where they block the infrared detection source for at least 3 seconds, the infrared detection source sends an electrical signal to the servo motor to drive the servo motor to start, thereby driving the quantitative cylinder to rotate half a circle so that the quantitative port is connected to the feed port, and this state is maintained for at least 10 seconds. Under the action of gravity, the crushed scraps in the quantitative cylinder will enter the crushing chamber. The scraps enter the recovery chamber and are collected by the staff. Since there is no channel connected to the interior on the outer wall of the quantitative cylinder except the quantitative port, the scraps continuously crushed by the crushing mechanism will accumulate at the feed port under the cover of the outer wall of the quantitative cylinder. When the servo motor drives the quantitative cylinder to continue to rotate half a circle and connects the quantitative port with the feed port, the scraps accumulated at the feed port will fall into the quantitative cylinder under the action of gravity, and the cycle will be completed, thereby completing the quantitative weighing operation of the plastic sheet scraps. The operation is convenient, which greatly improves the work efficiency of plastic sheet recycling. BRIEF DESCRIPTION OF THE DRAWINGS
