Description

Technical Field

[0001] This invention belongs to the field of crusher technology and relates to a chain tooth waste bar biting and crushing machine. Technical Background

[0002] In the production process of plastic zippers, the zipper teeth are injection molded onto the chain belt using an injection molding machine. The injection-molded zipper consists of two chain belts on both sides, two rows of chain teeth injection molded on opposite sides of the two chain belts, and a strip of waste chain teeth connecting the two rows of chain teeth (injection molding waste). The waste chain teeth strip is then separated from the zipper by an injection molding chain belt separator. After separation, the zipper enters the process of attaching the zipper head. The waste chain teeth strip is then recycled in a crusher.

[0003] However, ordinary injection molding waste crushers crush materials too finely, which filters out some of the fine powder after crushing, resulting in a low recycling rate. Summary of the Invention

[0004] In view of the above problems, the present invention provides a biting and shearing shredder for chain tooth waste strips, which has the advantages of complete shredding and high recycling rate.

[0005] The objective of this invention is achieved as follows:

[0006] A chain tooth waste strip biting and shearing crusher includes a feeding channel, a vertical strip cutting mechanism, a side-dividing and guiding mechanism and a biting and shearing mechanism arranged in sequence. The vertical strip cutting mechanism cuts the vertical strips on the waste strip. The side-dividing and guiding mechanism includes a waste strip channel and a vertical strip channel. The waste strip channel is also provided with a guide plate to guide the vertical strips into the vertical strip channel. The vertical strip channel is lower than the waste strip channel.

[0007] The biting and shearing mechanism includes two biting and shearing wheels, each with teeth evenly distributed around its circumference. The two biting and shearing wheels rotate in opposite directions, and during rotation, the teeth on the two biting and shearing wheels bite each other to achieve biting and shearing. The waste strip channel is set perpendicular to the rotation axis of the biting and shearing wheels. The guide plate guides the vertical strips cut by the vertical strip cutting mechanism into the vertical strip mechanism, separating the vertical strips from the waste strips. The vertical strips go directly into the recycling bin, while the waste strips enter the biting and shearing mechanism for crushing.

[0008] By setting up a feeding channel, a side-dividing guide mechanism, and a biting and shearing mechanism, the chain tooth waste strips can enter the biting and shearing mechanism in an orderly manner and at a fixed angle. The biting and shearing mechanism uses two biting and shearing wheels with evenly distributed blades around the circumference. Therefore, when the two biting and shearing wheels rotate, they can evenly bite and shear the chain tooth waste strips into segments, thus avoiding the generation of a large amount of powder and fine material, thereby increasing the recycling rate.

[0009] The present invention is further configured such that: the side-dividing guide mechanism includes two waste strip channels, two vertical channels and a guide bar, the two waste strip channels are arranged on both sides of the guide bar, the two vertical channels are arranged on both outer sides of the waste strip channels, the waste strip channels and vertical channels on the same side are adjacent to each other, and the vertical channels are lower than the waste strip channels, and a guide plate is provided between the two waste strip channels, the guide plate including two side wings respectively guiding the vertical bars on their respective waste strip channels into the vertical channels.

[0010] By using two waste strip channels, two vertical strip channels, and guide strips, the waste strips from the chain teeth can enter the biting and shearing mechanism in an orderly manner through the two channels, thereby improving the crushing efficiency. Furthermore, the guide plate guides the vertical strips cut by the vertical strip cutting mechanism into the vertical strip mechanism, separating the vertical strips from the waste strips. The vertical strips go directly into the recycling bin, while the waste strips enter the biting and shearing mechanism for crushing.

[0011] The present invention is further configured such that the guide bar is oscillatingly positioned between the two waste bar channels.

[0012] The present invention is further configured such that: a rotating shaft is connected to the middle of the guide strip, and a connecting rod is connected to the other end of the rotating shaft, and the other end of the connecting rod is rotatably connected to the output end of the swing cylinder.

[0013] With the above settings, the output end of the swing cylinder rotates the connecting rod, which in turn drives the connecting rod to reciprocate. This causes the rotating shaft to rotate clockwise and counterclockwise, which in turn causes the guide bar to swing repeatedly between clockwise and counterclockwise. This continuously guides the waste bar from different waste channels into the biting and shearing mechanism, thereby improving the crushing efficiency.

[0014] The present invention is further configured such that: the side-dividing guide mechanism also includes a waste strip detection mechanism, the waste strip detection mechanism being connected to a swing cylinder and controlling the swing of the guide strip.

[0015] By using a waste strip detection mechanism, the guide strip can be better controlled, making the rhythm of the guide strip's swing more accurate and reducing errors.

[0016] The present invention is further configured such that: the feeding channel includes an inlet and an outlet, the size of which gradually decreases from the inlet to the outlet; the outlet is greater than the width of the waste strip but less than the height of the vertical strip; specifically, the outlet is slightly larger than the width of the waste strip, so that the vertical strip can only pass through in a vertical state.

[0017] By adjusting the above settings, the posture of the waste strip in the feeding channel is adjusted so that the vertical strips face upwards, making it easier for the subsequent vertical strip cutting mechanism to cut the vertical strips.

[0018] The present invention is further configured such that: the vertical strip cutting mechanism includes a cutting frame disposed in front of the feeding channel, the cutting frame is provided with a cutting cylinder and two cutting tools, the cutting tools include a cutting arm and a cutting head disposed below the cutting arm, the cutting arm is rotatably disposed on the cutting frame, the upper ends of the two cutting arms form an opening, the extended end of the cutting cylinder is provided with a conical part, the conical part enters from the opening to enlarge the opening so that the cutting head below the cutting arm performs a biting action.

[0019] By setting up a vertical strip cutting mechanism, the vertical strips of the chain tooth scrap strip are cut off before entering the biting and cutting mechanism. If the vertical strips are not cut off, the biting and cutting wheel will inevitably change the shape of the scrap strip in the biting and cutting wheel when it bites the vertical strip position, thus affecting the stability of biting and cutting.

[0020] The present invention is further configured such that: the vertical strip cutting mechanism further includes a vertical strip detection device, which is connected to the cutting cylinder and controls the cutting head to perform a biting action.

[0021] With the above settings, when the vertical strip detection device detects a vertical strip, it controls the cutting cylinder to drive the cutting blade head to perform a biting action to cut off the vertical strip, thereby achieving better automation.

[0022] The present invention is further configured such that: the vertical strip cutting mechanism is also provided with a vibrating plate, which is located below the waste strip channel.

[0023] The vibratory feeder makes the conveying of the chain tooth waste strips smoother.

[0024] The outstanding and beneficial technical effects of this invention compared to the prior art are as follows: by setting up a feeding channel, a vertical strip cutting mechanism, a side-dividing and guiding mechanism, and a biting and cutting mechanism, the chain tooth waste strips can enter the biting and cutting mechanism in an orderly manner and at a fixed angle. The biting and cutting mechanism uses two biting and cutting wheels with evenly distributed blades around the circumference. Therefore, when the two biting and cutting wheels rotate, they can evenly bite and cut the chain tooth waste strips into segments, thereby avoiding the generation of a large amount of powder and fine material, and thus increasing the recycling rate.

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0042] The chain tooth waste strip 1 includes waste strip 101 and vertical strip 102. Waste strip 101 is the injection waste from the main runner and branch runner of the injection mold, and vertical strip 102 is the injection waste from the sprue.

[0043] A chain tooth waste strip biting and shearing crusher includes a feeding channel 2, a vertical strip cutting mechanism 3, a side-dividing and guiding mechanism 4, and a biting and shearing mechanism 5 arranged in sequence.

[0044] The feeding channel 2 includes an inlet 201 and an outlet 202, which gradually decreases in size from the inlet 201 to the outlet 202. The outlet 202 is wider than the width of the chain tooth scrap strip 1 but shorter than the height of the vertical strip 102. This configuration adjusts the orientation of the scrap strip in the feeding channel so that the vertical strip faces upwards, facilitating the subsequent vertical strip cutting mechanism to cut the strip.

[0045] The vertical strip cutting mechanism 3 includes a cutting frame 301 located in front of the feeding channel 2. The cutting frame 301 has a notch 307 formed on it for waste strips to pass through. The cutting frame 301 is equipped with a cutting cylinder 302 and two cutting tools. The cutting tools include a cutting arm 303 and a cutting head 304 located below the cutting arm 303. The cutting arm 303 is rotatably mounted on the cutting frame 301. An opening 305 is formed between the upper ends of the two cutting arms 303. A tapered part 306 is provided at the extended end of the cutting cylinder 302. The tapered part 306 enters through the opening 305, making the opening 305 larger, thereby allowing the cutting head 204 below the cutting arm 303 to perform a biting action. By setting up the vertical strip cutting mechanism, the vertical strip 102 of the chain tooth waste strip is cut off before entering the biting and cutting mechanism. If the vertical strip is not cut off, the shape of the waste strip 101 in the biting and cutting wheel will inevitably change when the biting and cutting wheel bites the vertical strip position, thus affecting the stability of biting and cutting.

[0046] The vertical strip cutting mechanism also includes a vertical strip detection device 308 installed on the cutting frame 301. The vertical strip detection device 308 is connected to the cutting cylinder 302 and controls the cutting head 304 to perform a biting action. With the above configuration, when the vertical strip detection device detects the vertical strip 102, it controls the cutting cylinder 302 to drive the cutting head to perform a biting action to cut off the vertical strip 102, thereby better realizing automation.

[0047] The side-dividing guide mechanism 4 includes a waste strip channel 401 and a vertical strip channel 402. The waste strip channel 401 is also provided with a guide plate 403 to guide the vertical strip 402 into the vertical strip channel 402. The vertical strip channel 402 is lower than the waste strip channel 401.

[0048] The side-guiding mechanism includes two waste strip channels 401, two vertical channels 402, and a guide bar 404. The two waste strip channels 401 are located on both sides of the guide bar 404, and the two vertical channels 402 are located on the outer sides of the waste strip channels 401. The waste strip channels 401 and vertical channels 402 on the same side are adjacent, and the vertical channels 402 are lower than the waste strip channels 401. A guide plate 403 is provided between the two waste strip channels 401. The guide plate 403 includes two side wings 405, which guide the vertical strips 102 on their respective waste strip channels 401 into the vertical channels 402. Through the arrangement of the two waste strip channels 401, the two vertical channels 402, and the guide bar 404, the waste strips 101 can enter the biting and shearing mechanism in an orderly manner from the two channels, thereby improving the crushing efficiency. Furthermore, through the setting of the guide plate 403, the guide plate 403 guides the vertical strip 102 cut by the vertical strip cutting mechanism 3 into the vertical strip mechanism 402, separating the vertical strip 102 and the waste strip 101. The vertical strip 102 directly enters the recycling box 6, and the waste strip 101 enters the biting and shearing mechanism 5 to be crushed.

[0049] The guide bar 404 is oscillatingly positioned between the two waste bar channels 401. A rotating shaft 406 is connected to the middle of the guide bar 404, and a connecting rod is connected to the other end of the rotating shaft 406. The other end of the connecting rod is rotatably connected to the output end of the oscillating cylinder. Through this configuration, the output end of the oscillating cylinder rotatably connects to the connecting rod, causing the connecting rod to reciprocate. This, in turn, causes the rotating shaft to rotate clockwise and counterclockwise, thereby causing the guide bar to oscillate repeatedly between clockwise and counterclockwise. This continuously guides the waste bar from different waste channels into the biting and shearing mechanism, thus improving the shredding efficiency.

[0050] The side-dividing guide mechanism is also equipped with a vibratory plate 407, which is located below the waste strip channel 401.

[0051] The side-dividing guide mechanism also includes a waste strip detection mechanism, which is connected to a swing cylinder and controls the swing of the guide strip. The waste strip detection mechanism allows for better control of the guide strip, making its swing rhythm more accurate and reducing errors.

[0052] The biting and shearing mechanism 5 includes two biting and shearing wheels 501, with blades 502 evenly distributed around the circumference of the two biting and shearing wheels 501. The two biting and shearing wheels 501 rotate in opposite directions, and the blades 502 on the two biting and shearing wheels bite each other during rotation to achieve biting and shearing. The waste strip channel 401 is arranged perpendicularly to the rotating shaft 503 of the biting and shearing wheels 501. The biting and shearing mechanism also includes a motor 504 that drives the biting and shearing wheels to rotate.

[0053] By setting up the feeding channel 2, the vertical strip cutting mechanism 3, the side-dividing and guiding mechanism 4, and the biting and cutting mechanism 5, the waste strip 101 can enter the biting and cutting mechanism 5 in an orderly manner and at a fixed angle. The biting and cutting mechanism 5 has two biting and cutting wheels with evenly distributed blades around its circumference. Therefore, when the two biting and cutting wheels rotate, they can evenly bite and cut the chain tooth waste strip into segments, thus avoiding the generation of a large amount of powder and fine material, thereby increasing the recycling rate.

[0054] This invention features a simple structure, complete material fragments, and a high recovery rate.

[0055] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
