Description

Technical Field

[0001] This application relates to the field of crushing technology, specifically to an anti-jamming assembly roller shredding device. Background Technology

[0002] Roller shredders are widely used in many industrial fields such as solid waste treatment, resource recycling, biomass fuel preparation and chemical raw material pretreatment because of their compact structure and high crushing efficiency. These devices usually rely on one or more pairs of counter-rotating crushing rollers to squeeze and shear the input materials to achieve preliminary crushing or refinement of the materials.

[0003] For example, patent CN221985560U discloses a material anti-jamming device for a plastic shredder. This patent uses adjustable-angle double extrusion plates to form a dynamic compression space, pre-compressing materials such as plastic bottles to prevent clogging of the processing area when they directly enter the shredder. The angle of the extrusion plates is adjusted by a gear set to accommodate different material sizes.

[0004] To ensure smooth discharge of crushed materials and prevent jamming, a screening mechanism is usually installed at the discharge end. However, when processing materials with different characteristics or switching product specifications, traditional fixed aperture screens require frequent shutdowns to disassemble the screens, which takes a long time on average. This not only causes production capacity loss, but also increases the risk of material jamming due to the increased gap between the screens and the screens.

[0005] Therefore, it is necessary to provide an anti-jamming assembly roller shredding device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an anti-jamming assembly roller shredder, which solves the problem of frequent shutdowns and screen plate disassembly caused by the need to process materials with different characteristics or switch product specifications, resulting in production capacity loss.

[0015] The two sets of screening sections are adapted to overlap and cover the screening opening to form a first screening hole, and the two sets of screening sections are adapted to be staggered to form a second screening hole.

[0016] Furthermore, the screening section includes a cover fixedly disposed on one side of the fixed frame, the other end of the cover extending through the crushing tank to the outside.

[0017] Furthermore, a screw is installed inside the housing via a bearing. One end of the screw extends through the housing to the outer end and is connected to a handwheel. A spiral block is provided on the screw inside the housing. The screening plate is fixedly installed on the top of the spiral block, and multiple sets of screen holes are opened on the screening plate.

[0018] Furthermore, the fixed frame has symmetrically arranged sliding grooves inside, and the inner wall of the cover has a guide groove at the same height as the sliding groove inside the fixed frame.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figures 1-2 As shown, this application provides an anti-jamming assembly roller shredder, which is mainly used in the material crushing process in the fields of solid waste treatment and plastic recycling. Specifically, the roller shredder includes a support 1 and a crushing mechanism 2 installed at the upper end of the support 1. The crushing mechanism 2 includes a crushing tank 20 fixedly installed at the upper end of the support 1, and a guide port 24 communicating with the interior is opened at the top of the crushing tank 20. In order to prevent the material from accumulating at the inlet, a guide plate 26 is installed obliquely below the guide port 24, and a grinding port 28 is provided at the lower end of the guide plate 26 so that the material can be guided to the grinding port 28 at the bottom through the guide plate 26.

[0032] Furthermore, two sets of parallel crushing rollers 23 are arranged inside the crushing tank 20 directly below the grinding port 28. At the same time, motors 22 are fixedly installed on both sides of the crushing tank 20. The output end of the motor 22 passes through the crushing tank 20 and is fixedly connected to the crushing rollers 23 respectively, so as to drive the two sets of crushing rollers 23 to rotate synchronously in opposite directions inside the crushing tank 20.

[0033] Furthermore, a compression gap is formed between the two sets of crushing rollers 23 to allow material to pass through, so that the crushing rollers 23 can be driven to rotate in the opposite direction by starting the motor 22, thereby shearing and tearing the material passing through the gap;

[0034] To prevent material jamming during the crushing process, the motor 22 can be started to drive the crushing roller 23 to rotate in reverse, which can automatically peel off the material stuck in the roller gap. At the same time, a deflector 27 is rotatably installed at the junction of the guide plate 26 and the grinding port 28. One end of the deflector 27 extends laterally through the crushing tank 20 to the outside, and a deflector plate 29 is fixedly installed at the end of the deflector 27 located inside the crushing tank 20. When the material accumulates above the grinding port 28, the deflector 27 can be driven to reciprocate by an external drive mechanism (not shown in the figure), and the deflector plate 29 can be used to disperse the blocking material to ensure continuous feeding.

[0035] Meanwhile, a discharge port 40 is provided at the center of the bottom of the crushing tank 20 to facilitate the discharge of crushed material;

[0036] In order to enable screening of the crushed material and prevent material jamming after crushing, such as Figures 1-4 As shown, a screening mechanism 3 is provided between the crushing roller 23 and the discharge port 40. The screening mechanism 3 includes a funnel-shaped guide ring 30 installed below the crushing roller 23 so that the crushed material can fall in a concentrated manner.

[0037] The guide ring 30 is provided with a fixed frame 31 directly below the outlet, and a screening port 32 is provided in the center of the fixed frame 31 to facilitate subsequent screening operations.

[0038] To achieve dynamic screening adjustment, two identical screening sections 36 are provided on both sides of the fixed frame 31, thereby achieving the effect of adjusting the pore size.

[0039] Specifically, the screening section 36 includes a cover 360 fixedly disposed on one side of the fixed frame 31, and the other end of the cover 360 passes through the crushing tank 20 and extends to the outside;

[0040] Furthermore, a screw 361 is installed inside the housing 360 via a bearing. One end of the screw 361 extends through the housing 360 to the outer end and is connected to a handwheel 362, so that the user can drive the screw 361 to rotate inside the housing 360 by turning the handwheel 362.

[0041] Meanwhile, a spiral block 365 is provided on the screw 361 inside the cover 360. A screening plate 363 is fixedly provided on the top of the spiral block 365. The screening plate 363 has multiple sets of screen holes 364 to facilitate subsequent screening operations.

[0042] Furthermore, symmetrical sliding grooves 33 are provided inside the fixed frame 31, and a guide groove (not shown in the figure) of the same height as the sliding groove 33 of the fixed frame 31 is provided on the inner wall of the cover 360. The screening plate 363 is slidably disposed on the guide groove, and the guide groove is connected to the sliding groove 33 of the fixed frame 31, so that the user can drive the screw 361 to move the screening plate 363 from the guide groove to the sliding groove 33 by rotating the handwheel 362 until the screening port 32 of the fixed frame 31 is covered and blocked, and then the movement can be stopped to carry out subsequent screening operations.

[0043] It should be noted that the screening plate 363 of one set of screening sections 36 slides along the lower end of the chute 33, while the screening plate 363 of the other set of screening sections 36 slides along the upper end of the chute 33. The initial position of the two sets of screening sections 36 is that both sets of screening plates 363 are located at the position covering the screening port 32, and the screen holes 364 on the two sets of screening plates 363 overlap.

[0044] When screening is required, in the initial state, the two sets of screening plates 363 completely cover the screening opening 32, and their screen holes 364 are completely overlapping. At this time, the screen hole 364 is at its largest size. When it is necessary to reduce the size of the screen hole 364, the handwheel 362 of one set of screening parts 36 is rotated in the opposite direction to drive the right screening plate 363 to retract into the cover 360. The screen holes 364 of the two sets of screening plates 363 are misaligned and blocked due to relative displacement, forming a reduced effective aperture.

[0045] During the adjustment process, the material is gathered at the screening port 32 by the guide ring 30. Particles that meet the size requirements fall into the feed port 40 through the staggered screen holes 364, while oversized particles are retained on the surface of the screening plate 363.

[0046] When it is necessary to clean the residue, the two sets of handwheels 362 can be rotated simultaneously to make the screening plate 363 completely retract into the cover 360. During the retraction process, the residue will be blocked until the screening port 32 is fully open, thereby realizing the slag discharge operation.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
