Description

Technical Field

[0001] This utility model relates to the field of crushing, and more specifically, it relates to a recycled raw material crusher for the production of recycled low-modulus fibers. Background Technology

[0002] Recycled low-modulus fiber refers to chemical fibers with low elastic modulus made from recycled polymer materials. During the raw material pretreatment stage, a crusher may be used to crush recyclable plastics into appropriately sized particles before melting. Existing plastic crushers typically include a frame with a feed hopper, crushing mechanism, and screen plate. Common crushing mechanisms include single-shaft, dual-shaft, hammer crusher, and four-shaft composite crusher structures. To facilitate cleaning of the crushing mechanism, most feed hoppers are currently rotatably connected to the frame. Tilting the feed hopper exposes the crushing mechanism, making cleaning easier. However, during plastic crushing, changes in production demands, wear, and screen blockage necessitate cleaning or replacement of the screen plate. Most existing screens are fixed at the bottom of the crushing mechanism, obscuring it, making cleaning and replacement inconvenient and time-consuming, which reduces production efficiency.

[0003] Based on the above, the purpose of this utility model is to provide a recycled raw material crusher for the production of recycled low-modulus fibers, so as to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a recycled raw material crusher for the production of recycled low-modulus fibers. This utility model connects mounting plates to both sides of the frame and installs the crushing mechanism between the two mounting plates. It also provides a second drive mechanism to drive the mounting plates to flip. The user can drive the mounting plates to flip outward through the second drive mechanism, which in turn drives the crushing mechanism to flip outward and exposes the screen plate. At this time, the user can clean or replace the screen plate, making the cleaning and replacement of the screen plate more convenient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a recycled raw material crusher for the production of recycled low-modulus fibers, including a frame, a feeding hopper, a crushing mechanism and a screen plate are provided on the frame, the feeding hopper is rotatably connected to the frame, mounting plates are provided on both sides of the crushing mechanism, and the mounting plates on both sides are rotatably connected to the frame, and a first driving mechanism for driving the feeding hopper to flip and a second driving mechanism for driving the mounting plates on both sides to flip are provided on the frame.

[0006] By adopting the above technical solution, when the crushing mechanism needs to be cleaned, the feed hopper is rotated by the drive mechanism one, thereby exposing the crushing mechanism. At this time, the user can clean or maintain the crushing mechanism. When the screen plate needs to be cleaned or replaced, the mounting plates on both sides are rotated by the drive mechanism two, thereby rotating the crushing mechanism until the screen plate below is exposed. At this time, the screen plate can be cleaned or replaced.

[0007] The present invention is further configured such that: the drive mechanism includes an electric push rod at one end rotatably connected to the frame, and the other end of the electric push rod is rotatably connected to the feed hopper.

[0008] The present invention is further configured such that: the second driving mechanism includes two driving rods, which are respectively fixedly connected to both sides of the feed hopper, and both sides of the mounting plate are provided with driving grooves for the driving rods to be inserted and moved, and the driving grooves are arc-shaped.

[0009] The present invention is further configured such that: both sides of the frame are fixedly connected to support plates for supporting the mounting plate.

[0010] The present invention is further configured such that: the mounting plate is provided with a plug-in portion, and the support plate is provided with a plug-in groove for the plug-in portion to be inserted.

[0011] The present invention is further configured such that the cross-sections of the plug-in portion and the plug-in groove are both isosceles trapezoids.

[0012] The present invention is further configured such that: the crushing mechanism includes two crushing rollers, the two sides of the two crushing rollers are respectively rotatably connected to two mounting plates, and the mounting plates are provided with a driving mechanism three for driving the two crushing rollers to rotate in opposite directions.

[0013] The present invention is further configured such that: the driving mechanism includes a motor fixedly connected to a mounting plate on one side, a belt pulley transmission assembly is provided between the motor and the crushing roller on one side, and a linkage gear is fixedly connected to both crushing rollers.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This utility model connects mounting plates to both sides of the frame, and then installs the crushing mechanism between the two mounting plates. It also provides a second drive mechanism to drive the mounting plates to flip. The user can drive the mounting plates to flip outward through the second drive mechanism, which in turn drives the crushing mechanism to flip outward and exposes the screen plate. At this time, the user can clean or replace the screen plate, making the cleaning and replacement of the screen plate more convenient. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] A recycled raw material crusher for the production of recycled low-modulus fibers, such as Figures 1 to 6 As shown, the device includes a frame 1, on which a feed hopper 2, a crushing mechanism, and a screen plate 3 are mounted. The feed hopper 2 is rotatably connected to the frame 1, and the screen plate 3 is detachably connected to the base frame by bolts or other tools. The crushing mechanism is mounted on both sides of the crushing mechanism, and the crushing mechanism is installed between the two mounting plates 4. Both mounting plates 4 are rotatably connected to the frame 1. The mounting plates 4 and the rotatable connection points of the feed hopper 2 are on the same axis. The frame 1 is equipped with a first drive mechanism for driving the feed hopper 2 to rotate and a second drive mechanism for driving the two mounting plates 4 to rotate.

[0028] Furthermore, the drive mechanism includes an electric push rod 5 with one end rotatably connected to the frame 1, and the other end (extended end) of the electric push rod 5 rotatably connected to the feed hopper 2.

[0029] Furthermore, the second drive mechanism includes two drive rods 6, which are fixedly connected to both sides of the feed hopper 2. Each side mounting plate 4 has a drive groove 7 for the drive rods 6 to insert and move. The drive groove 7 is arc-shaped. Further, multiple sets of drive rods and drive grooves can be provided on the same side.

[0030] Furthermore, support plates 8 are fixedly connected to both sides of the frame 1 to support the mounting plate 4. In normal operation, the mounting plate is clamped between the support plate and the drive rod, thereby limiting the crushing mechanism. Further, the mounting plate and support plate, as well as the frame and feed hopper, can be further fixed and limited using bolts or other tools.

[0031] Furthermore, the mounting plate 4 is provided with a plug-in part 9, and the support plate 8 is provided with a plug-in groove for the plug-in part 9 to be inserted.

[0032] Furthermore, both the insertion part 9 and the insertion slot have isosceles trapezoidal cross sections.

[0033] Furthermore, the crushing mechanism includes two crushing rollers 10, the two ends of which are rotatably connected to the mounting plates 4 on both sides. The mounting plates 4 are provided with a drive mechanism 3 for driving the two crushing rollers 10 to rotate in opposite directions.

[0034] Furthermore, the drive mechanism three includes a motor 11 fixedly connected to a mounting plate 4 on one side. A belt pulley transmission assembly is provided between the motor 11 and the crushing roller 10 on one side. The belt pulley transmission assembly includes two belt pulleys fixedly connected to the motor output shaft and the crushing roller respectively. A transmission belt is sleeved between the two belt pulleys. A linkage gear 12 is fixedly connected to each of the two crushing rollers 10. The two linkage gears mesh with each other.

[0035] Working principle: When it is necessary to crush recycled plastic, start the motor 11. The motor 11 will drive one crushing roller 10 to rotate through the belt pulley transmission assembly. This crushing roller 10 will drive the other crushing roller 10 to rotate in the opposite direction through two linkage gears 12. At this time, the user can pour the raw material to be crushed into the feed hopper 2. The raw material will slide along the inner cavity of the feed hopper 2 into the space between the two crushing rollers 10 for crushing. The crushed raw material particles will then pass through the screen plate 3 and be discharged. When it is necessary to clean or maintain the crushing rollers 10 of the crushing mechanism, remove the bolts between the feed hopper and the frame, and then drive the extended end of the electric push rod 5 to retract, thereby driving the feed hopper 2 to flip backward until the crushing rollers 10 of the crushing mechanism are exposed. At this time, the user can clean or maintain the crushing mechanism. During this process, the drive rod 6 will move along the trajectory of the drive groove 7 to avoid obstacles and will not cause the mounting plate 4 to shift position.

[0036] When cleaning or replacement of the screen plate 3 is required, remove the bolts between the mounting plate and the support plate, and then drive the extended end of the electric push rod 5 to continue retracting. During this process, the drive rod 6 will move to the end of the drive groove 7. At this time, the drive rod 6 will push the mounting plate 4 to flip backward, thereby driving the crushing mechanism to flip backward until the screen plate 3 below is exposed. At this time, the screen plate 3 can be cleaned or replaced. With this setting, only one electric push rod 5 is needed to achieve the flipping of the feed hopper 2 and the crushing mechanism, thereby exposing the crushing roller 10 or the screen plate 3 for easy cleaning or maintenance by the user. It should be mentioned that the crushing mechanism in this embodiment uses a dual-shaft crushing structure. However, the dual-shaft crushing structure can be replaced by a single-shaft crushing structure, a hammer crushing structure, or a four-shaft composite crushing structure, etc. As long as the crushing structure is installed on the mounting plates 4 on both sides, the technical effect of this solution can be achieved.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
