Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment for injection molded parts, and particularly to a waste recycling and treatment device for injection molded parts. Background Technique

[0002] A waste recycling and treatment device is a device or system for recycling and treating waste, aiming to convert waste into reusable resources or reduce environmental pollution. An injection molded part waste recycling and treatment device is a device specifically used to treat waste generated during the injection molding production process. Such a device usually includes components such as a crusher, a separation box, an air suction pipe, a storage box, etc., and can perform operations such as crushing, dust suction, and separation on the waste to make it into reusable granular materials.

[0003] As disclosed in a waste crushing and recycling treatment device for plastic injection molded parts in Chinese Patent CN118700392B, through the coordinated operation of a driving mechanism, an air flow impact mechanism, and a dust filtering mechanism, efficient crushing of waste and effective collection of dust are achieved; the driving mechanism ensures that the treatment mechanism can stably crush plastic parts multiple times. The air flow impact mechanism not only enables the crushed plastic fragments to flow back for further treatment, but also can drive the dust generated during the treatment process away from the treatment mechanism to prevent dust leakage; the dust filtering mechanism collects the exported dust, preventing the accumulation and leakage of dust inside the device, thereby maintaining the cleanliness of the device and a good working environment; therefore, this device improves the efficiency and crushing quality of plastic waste treatment, while reducing dust pollution, and plays a positive role in improving the production environment and the operating stability of the device.

[0004] For this structure, although the waste can be crushed, this structure is inconvenient for anti-blocking feeding, resulting in easy blockage of waste. Therefore, we propose a waste recycling and treatment device for injection molded parts that can perform anti-blocking crushing on waste to improve the crushing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a waste recycling and treatment device for injection molded parts to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A waste recycling and treatment device for injection molded parts, including a feed hopper, a discharge hopper is arranged below the feed hopper, a bracket is arranged outside the discharge hopper, and a processing component is arranged below the feed hopper. The processing component includes a crushing component arranged below the feed hopper, and a cleaning component is arranged inside the crushing component.

[0007] Preferably, the crushing assembly includes a crushing box fixedly installed at the bottom of the feed hopper. An installation frame is fixedly installed on the outer wall of the crushing box. A motor is fixedly installed on the top surface of the installation frame. A driving crushing roller is fixedly installed at the output end of the motor. A driving gear is sleeved on the outer wall of the driving crushing roller away from the motor. A driven gear meshes with the outer wall of the driving gear. A driven crushing roller is sleeved inside the driven gear. An elliptical disc is fixedly installed at the end of the driving crushing roller. A pressing plate is slidably arranged on the outer wall of the elliptical disc. A protective cover is fixedly installed on the outer wall of the crushing box. A sliding frame is fixedly installed at the bottom end of the crushing box. An aggregate box is slidably arranged on the outer wall of the sliding frame. A guiding plate is fixedly installed on the inner wall of the crushing box.

[0008] Preferably, the cleaning assembly includes a chute opened on the inner wall of the crushing box. A first magnetic plate is fixedly installed on the inner wall of the chute. A second magnetic plate is slidably arranged inside the chute. A sliding plate is fixedly installed on the side wall of the second magnetic plate. A brush is fixedly installed at one end of the sliding plate away from the second magnetic plate.

[0009] Preferably, there are two elliptical discs, which are symmetrically distributed with respect to the center line of the crushing box. Under the restriction of the two rotating elliptical discs, they slide and squeeze with the end of the pressing plate, causing the elliptical discs to drive the crushing box and the sliding frame to move upward, making the crushing box drive the feed hopper to vibrate, so as to achieve the effect of preventing material blockage.

[0010] Preferably, one end of the pressing plate away from the elliptical disc is fixedly installed on the outer wall of the aggregate box, and one end of the pressing plate away from the aggregate box is arc-shaped. With the arc-shaped pressing plate, the elliptical disc can be smoothly squeezed with it.

[0011] Preferably, the outer wall of the aggregate box is fixedly installed with a support, and the bottom of the aggregate box is fixedly installed with a discharge hopper. Supported by the support, the crushing work can be carried out stably. The waste materials after crushing are transported into the discharge hopper through the aggregate box, and the discharge is realized through the discharge hopper.

[0012] Preferably, the guiding plate is inclined and arranged inside the crushing box. There are two guiding plates, which are symmetrically distributed with respect to the center line of the top surface of the crushing box. Under the restriction of the inclined guiding plates, the waste materials can be guided and guided between the driving crushing roller and the driven crushing roller.

[0013] Preferably, the first magnetic plate and the second magnetic plate repel each other magnetically. The outer wall of the sliding plate is slidably arranged inside the chute. Under the restriction of magnetic repulsion, the first magnetic plate pushes the second magnetic plate, the sliding plate and the brush, so that the brush is in close contact with the outer walls of the driving crushing roller and the driven crushing roller.

[0014] Preferably, there are two sliding plates, which are symmetrically distributed with respect to the center line of the crushing box. Under the restriction of the two groups of sliding plates, the driving crushing roller and the driven crushing roller can be cleaned by the brushes respectively.

[0015] Preferably, one end of the slide plate away from the second magnetic plate is arranged in an arc shape, and the brush bristles are wear-resistant metal brushes. Under the restriction of the slide plate with an arc-shaped end, the slide plate can smoothly squeeze against the outer walls of the active crushing roller and the driven crushing roller. Under the restriction of the brush bristles made of wear-resistant metal brush material, the friction and wear between the brush bristles and the active crushing roller and the driven crushing roller can be avoided, and the service life of the brush bristles can be prolonged.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The waste recycling and treatment device for injection molded parts includes a crushing component as one of its parts. When processing injection molded parts, waste will be generated and needs to be recycled and treated. During the treatment process, the waste needs to be crushed. The waste is added into the crushing box from the feed hopper. At this time, the motor is started, and the active crushing roller fixedly installed at the output end thereof rotates accordingly. The active crushing roller drives the active gear sleeved on its outer wall to rotate. Since the active gear meshes with the driven gear, and the inner part of the driven gear is sleeved with the driven crushing roller, under its restriction, the active gear drives the driven gear to rotate, and the driven gear drives the driven crushing roller to rotate accordingly. The active crushing roller and the driven crushing roller move in opposite directions to crush the waste. During the process of the feed hopper feeding materials into the crushing box, anti-blocking treatment needs to be carried out on the waste to improve the crushing efficiency. When the active crushing roller rotates, the elliptical disk fixedly installed at one end away from the motor rotates accordingly. Since the end of the pressing plate is fixedly installed with the aggregate box and the end of the pressing plate is arranged in an arc shape, under its restriction, the rotating elliptical disk slides and presses against the pressing plate, causing the elliptical disk to drive the crushing box and the sliding frame to move upward. The sliding frame slides in the direction away from the aggregate box. When the elliptical disk stops pressing against the pressing plate during rotation, the elliptical disk drives the crushing box and the sliding frame to move downward as a whole, reciprocatingly moving the crushing box and the sliding frame up and down to vibrate the waste above the active crushing roller and the driven crushing roller, preventing it from blocking inside the feed hopper and the crushing box. Under the restriction of the guiding plate, the waste can be centrally guided between the active crushing roller and the driven crushing roller. Under the restriction of the protective cover, the active gear and the driven gear can be accurately meshed. This structure can crush the waste and make the crushing box move up and down to avoid waste blockage.

[0018] 2. The waste recycling and treatment device for injection molded parts includes a cleaning component as one of its parts. When the active crushing roller and the driven crushing roller crush the waste, scraps are easily attached to their outer walls. At this time, under the restriction of the brush bristles, the scraps between the crushing teeth of the active crushing roller and the driven crushing roller can be cleaned. Under the restriction of the magnetic repulsion between the first magnetic plate and the second magnetic plate, the first magnetic plate pushes the second magnetic plate, the slide plate and the brush bristles, causing the brush bristles to closely clean the active crushing roller and the driven crushing roller. Since one end of the slide plate away from the second magnetic plate is arranged in an arc shape, under its restriction, the slide plate smoothly slides against the outer walls of the active crushing roller and the driven crushing roller, preventing it from getting stuck. This structure can clean the scraps attached between the crushing teeth of the active crushing roller and the driven crushing roller, enabling the active crushing roller and the driven crushing roller to better crush the waste.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example 1: A preferred embodiment of a waste recycling and treatment device for injection molded parts provided by the present invention is as Figures 1 to 6 shown: A waste recycling and treatment device for injection molded parts includes a feed hopper 1;

[0031] A discharge hopper 2 is provided below the feed hopper 1;

[0032] A support 3 is provided outside the discharge hopper 2;

[0033] And a processing assembly 4 provided below the feed hopper 1. The processing assembly 4 includes a crushing assembly 41 provided below the feed hopper 1. The crushing assembly 41 includes a crushing box 420 fixedly installed at the bottom of the feed hopper 1. An installation frame 411 is fixedly installed on the outer wall of the crushing box 420. A motor 412 is fixedly installed on the top surface of the installation frame 411. The output end of the motor 412 is fixedly installed with a main crushing roller 413. A main gear 414 is sleeved on the outer wall of the main crushing roller 413 away from the motor 412. A driven gear 415 meshes with the outer wall of the main gear 414. A driven crushing roller 416 is sleeved inside the driven gear 415. An elliptical plate 417 is fixedly installed at the end of the main crushing roller 413. A pressing plate 418 is slidably arranged on the outer wall of the elliptical plate 417. A protective cover 419 is fixedly installed on the outer wall of the crushing box 420. A sliding frame 422 is fixedly installed at the bottom end of the crushing box 420. An aggregate box 423 is slidably arranged on the outer wall of the sliding frame 422. A guiding plate 421 is fixedly installed on the inner wall of the crushing box 420.

[0034] In this embodiment, when processing injection molded parts, waste will be generated and needs to be recycled. During the processing, the waste needs to be crushed. The waste is added into the interior of the crushing box 420 from the feed hopper 1. At this time, the motor 412 is started, and the driving crushing roller 413 fixedly installed at the output end thereof rotates accordingly. The driving crushing roller 413 drives the driving gear 414 sleeved on its outer wall to rotate accordingly. Since the driving gear 414 meshes with the driven gear 415, and the interior of the driven gear 415 is sleeved with the driven crushing roller 416, under its restriction, the driving gear 414 drives the driven gear 415 to rotate, and the driven gear 415 drives the driven crushing roller 416 to rotate accordingly. The driving crushing roller 413 and the driven crushing roller 416 move in opposite directions to crush the waste. During the process of the feed hopper 1 feeding the crushing box 420, anti-blocking treatment needs to be carried out on the waste to improve the crushing efficiency. When the driving crushing roller 413 rotates, the elliptical disc 417 fixedly installed at the end away from the motor 412 rotates accordingly. Since the end of the pressing plate 418 is fixedly installed with the aggregate box 423, and the end of the pressing plate 418 is arranged in an arc shape, under its restriction, the rotating elliptical disc 417 slides and presses against the pressing plate 418, causing the elliptical disc 417 to drive the crushing box 420 and the sliding frame 422 to move upward. The sliding frame 422 slides in the direction away from the outside of the aggregate box 423. When the elliptical disc 417 stops pressing against the pressing plate 418 during rotation, the elliptical disc 417 drives the crushing box 420 and the sliding frame 422 to move downward as a whole, reciprocatingly causing the crushing box 420 and the sliding frame 422 to move up and down, vibrating the waste above the driving crushing roller 413 and the driven crushing roller 416, and preventing it from being blocked inside the feed hopper 1 and the crushing box 420. Under the restriction of the guiding plate 421, the waste can be centrally guided between the driving crushing roller 413 and the driven crushing roller 416. Under the restriction of the protective cover 419, the driving gear 414 and the driven gear 415 can be accurately meshed. This structure can crush the waste and can move the crushing box 420 up and down to avoid waste blockage.

[0035] Among them, there are two elliptical discs 417, which are symmetrically distributed with respect to the center line of the crushing box 420. Under the restriction of the two rotating elliptical discs 417, they slide and press against the end of the pressing plate 418, causing the elliptical disc 417 to drive the crushing box 420 and the sliding frame 422 to move upward, and causing the crushing box 420 to drive the feed hopper 1 to vibrate to achieve the effect of preventing material blockage.

[0036] Among them, the end of the pressing plate 418 away from the elliptical disc 417 is fixedly installed on the outer wall of the aggregate box 423, and the end of the pressing plate 418 away from the aggregate box 423 is arranged in an arc shape. With the pressing plate 418 arranged in an arc shape, the elliptical disc 417 smoothly presses against it.

[0037] Among them, the outer wall of the aggregate box 423 is fixedly installed with the bracket 3, and the bottom of the aggregate box 423 is fixedly installed with the discharge hopper 2. Supported by the bracket 3, the crushing work can be carried out stably. The waste materials after crushing are conveyed from the aggregate box 423 into the discharge hopper 2, and the discharge is realized through the discharge hopper 2.

[0038] Among them, the guiding plate 421 is inclined and arranged inside the crushing box 420. The number of guiding plates 421 is two, symmetrically distributed with respect to the center line of the top surface of the crushing box 420. Under the restriction of the inclined guiding plate 421, the waste materials can be guided and led between the active crushing roller 413 and the driven crushing roller 416.

[0039] Embodiment 2: On the basis of Embodiment 1, a preferred embodiment of a waste recycling and treatment device for injection molded parts provided by the present invention is as Figures 1 to 6 shown: The cleaning assembly 43 includes a chute 431 opened on the inner wall of the crushing box 420. A first magnetic plate 432 is fixedly installed on the inner wall of the chute 431. A second magnetic plate 433 is slidably arranged inside the chute 431. A sliding plate 434 is fixedly installed on the side wall of the second magnetic plate 433. A brush hair 435 is fixedly installed at one end of the sliding plate 434 away from the second magnetic plate 433.

[0040] In this embodiment, when the active crushing roller 413 and the driven crushing roller 416 crush the waste materials, broken materials are easily attached to their outer walls. At this time, under the restriction of the brush hair 435, the broken materials between the crushing teeth of the active crushing roller 413 and the driven crushing roller 416 can be cleaned. Under the restriction of the magnetic repulsion between the first magnetic plate 432 and the second magnetic plate 433, the first magnetic plate 432 pushes the second magnetic plate 433, the sliding plate 434 and the brush hair 435, so that the brush hair 435 tightly contacts the outer walls of the active crushing roller 413 and the driven crushing roller 416. Since one end of the sliding plate 434 away from the second magnetic plate 433 is arranged in an arc shape, under its restriction, the sliding plate 434 smoothly slides on the outer walls of the active crushing roller 413 and the driven crushing roller 416, avoiding jamming. This structure can clean the broken materials attached between the crushing teeth of the active crushing roller 413 and the driven crushing roller 416, enabling the active crushing roller 413 and the driven crushing roller 416 to better crush the waste materials.

[0041] Among them, the first magnetic plate 432 and the second magnetic plate 433 are magnetically repulsive. The outer wall of the sliding plate 434 is slidably arranged inside the chute 431. Under the restriction of magnetic repulsion, the first magnetic plate 432 pushes the second magnetic plate 433, the sliding plate 434 and the brush hair 435, so that the brush hair 435 tightly contacts the outer walls of the active crushing roller 413 and the driven crushing roller 416.

[0042] Among them, the number of sliding plates 434 is two, symmetrically distributed with respect to the center line of the crushing box 420. Under the restriction of the two groups of sliding plates 434, the active crushing roller 413 and the driven crushing roller 416 can be cleaned by the brush hair 435 respectively.

[0043] Among them, one end of the skateboard 434 away from the second magnetic plate 433 is arranged in an arc shape. The brush bristles 435 are wear-resistant metal brushes. Under the restriction of the skateboard 434 arranged in an arc shape at the end, the skateboard 434 can be smoothly extruded with the outer walls of the active crushing roller 413 and the driven crushing roller 416. Under the restriction of the brush bristles 435 made of wear-resistant metal brush material, the friction and wear between the brush bristles 435 and the active crushing roller 413 and the driven crushing roller 416 can be avoided, and the service life of the brush bristles 435 can be prolonged.

[0044] The above is only a schematic specific implementation manner of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or multiple features can be combined for use. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
