Description

Technical Field

[0001] This utility model relates to the field of crushing devices, and in particular to a crushing device for foamed nylon elastomers. Background Technology

[0002] Foamed nylon elastomer is a new type of polymer material. It is an elastic material made from nylon as the matrix through a foaming process. Due to its good cushioning performance, stable chemical properties, and good heat and sound insulation properties, it is widely used in various fields. Foamed nylon elastomer products are recyclable. Crushing the recycled foamed nylon elastomer waste is an important step in realizing resource recycling. The crushed material can be used as a recycled raw material, mixed with new material in a certain proportion, and reused to produce foamed nylon elastomer products, which helps to reduce production costs and reduce environmental pollution.

[0003] The existing patent number CN214725614U discloses a plastic crusher, which has a baffle installed inside the machine casing. The baffle is located below the crushing roller, which can reduce the accumulation of plastic particles in the dead corner between the crushing roller and the screen, so that these plastic particles can fully contact the crushing roller and be fully crushed, thereby improving the crushing efficiency of plastic and improving the uniformity of plastic particle size distribution.

[0004] However, the existing crushing device directly feeds in the material during use, lacking guidance for the material to be crushed. This easily leads to material accumulation on the crushing roller, for example, material accumulating at one end of the crushing roller while the other end of the crushing roller does not perform crushing work. The top of the accumulated material is also difficult to contact the crushing roller, which makes it easy for the material not to be crushed in time, thus affecting the crushing efficiency. Furthermore, when the material falls into the crusher, it is easy to collide with the inner wall of the crusher, generating noise and causing noise pollution, which affects the working environment. Summary of the Invention

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a foamed nylon elastomer crushing device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foamed nylon elastomer crushing device, comprising a crusher body and a connecting frame installed on the crusher body, and a guide frame disposed on the connecting frame. The guide frame comprises a frame body, a fixing frame, a telescopic cylinder, a transmission plate, a guide plate, a rotating shaft, and a buffer column. The frame body is installed on the connecting frame, and a movable guide plate is disposed inside the frame body. The fixing frame is disposed on the frame body, and a telescopic cylinder is rotatably installed inside the fixing frame.

[0007] Several buffer posts located outside the guide plate are installed inside the frame;

[0008] A transmission plate is rotatably mounted on the piston rod of the telescopic cylinder;

[0009] The guide plate is rotatably connected to the inside of the frame via its mounted pivot, and the pivot passes through the inside of the frame and is rotatably connected to the transmission plate.

[0010] Preferably, a support frame is installed at the bottom edge of the crusher body.

[0011] Preferably, the upper end of the frame extends upward at an angle to form a feed inlet.

[0012] Preferably, a buffer sheet is attached to each of the left and right end faces of the guide plate.

[0013] Preferably, a guide post is embedded at the bottom of the guide plate, and the guide post is movably connected to the inner side of a guide groove opened on the inner wall of the frame. The guide groove is an arc shape corresponding to the swing trajectory of the guide post.

[0014] Preferably, the buffer column includes a fixed rod installed on the inner wall of the frame and a buffer head disposed on the fixed rod. The free end of the fixed rod is coaxially provided with a threaded head, and the threaded head is threadedly connected to the inner side of the threaded groove opened on the buffer head.

[0015] Preferably, the end of the buffer head away from the fixed rod has a hemispherical structure.

[0016] The beneficial effects of this utility model are:

[0017] This invention uses a telescopic cylinder in conjunction with a transmission plate and a rotating shaft to drive a guide plate to oscillate left and right within the frame, thereby guiding and conveying the foamed nylon elastomer to be crushed to the left and right ends of the crushing roller inside the crusher body. This reduces the accumulation of foamed nylon elastomer on one end of the crushing roller, avoids local overload or idling of the crushing roller, and helps improve crushing efficiency. Furthermore, the buffer column cushions the foamed nylon elastomer, reducing the noise generated by the collision between the foamed nylon elastomer and the crusher body, thus improving the working environment.

Detailed Implementation

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] like Figure 1 As shown, this utility model provides a foamed nylon elastomer crushing device, including a crusher body 1 and a connecting frame 3 locked and fixed on the crusher body 1;

[0026] In this embodiment, a support frame 2 is vertically installed at the bottom edge of the crusher body 1. The support frame 2 is used to provide support for the crusher body 1, and at the same time, it is convenient to put the collection device into the support frame 2 to collect the crushed foamed nylon elastomer.

[0027] like Figures 2 to 5 As shown, this embodiment also includes a guide frame 4 disposed in the connecting frame 3. The guide frame 4 includes a frame body 41 installed at the edge of the top surface of the connecting frame 3, a fixing frame 42 disposed at the rear end surface of the frame body 41, a guide plate 45 disposed in the frame body 41, and a telescopic cylinder 43 rotatably installed in the fixing frame 42. The telescopic cylinder 43 is a telescopic cylinder.

[0028] Several buffer columns 49 are installed inside the frame 41, which are distributed on the left and right sides of the guide plate 45.

[0029] A transmission plate 44 is rotatably mounted on the piston rod of the telescopic cylinder 43;

[0030] The guide plate 45 is rotatably connected to the inside of the frame 41 via a rotating shaft 46 fixedly installed on its top. The rotating shaft 46 moves horizontally through the inner wall of the frame 41 and is rotatably connected to the end of the transmission plate 44 away from the telescopic cylinder 43.

[0031] The upper end of the frame 41 extends forward and upward at an angle to form a feed inlet 48, which reduces the foamed nylon elastomer from bouncing and splashing away from the inside of the frame 41 when it is crushed.

[0032] In this embodiment, a buffer sheet 47 made of nitrile rubber is attached to each of the left and right end faces of the guide plate 45 to provide buffer for the foamed nylon elastomer and reduce the collision between the foamed nylon elastomer and the guide plate 45 during introduction, causing it to pop out of the inner side of the frame 41.

[0033] In this embodiment, a cylindrical guide post 410 is fixedly embedded in the bottom of the guide plate 45. The guide post 410 is movably connected to the inner side of the guide groove 411 opened on the inner wall of the frame 41. The guide groove 411 is an arc shape corresponding to the swing trajectory of the guide post 410. The guide post 410 and the guide groove 411 provide auxiliary positioning for the guide plate 45, which improves the stability of the guide plate 45 during the swing process.

[0034] In this embodiment, the buffer column 49 includes a fixing rod 491 that is horizontally locked and fixed to the inner wall of the frame 41, and a buffer head 492 made of nitrile rubber that is set on the fixing rod 491. The free end of the fixing rod 491 is coaxially provided with a threaded head 493, and the threaded head 493 is threadedly connected to the inner side of the threaded groove 494 opened on the buffer head 492.

[0035] Among them, the end of the buffer head 492 away from the fixed rod 491 is a hemispherical structure. Compared with the design of a flat surface or other sharp edges, the wear on the hemispherical structure will be more uniform and less prone to local excessive wear. This not only extends the service life of the buffer head 492, but also ensures the noise reduction effect under long-term use.

[0036] Specifically, by controlling the pneumatic equipment of the external telescopic cylinder 43, compressed air is controlled to enter and exit different chambers of the telescopic cylinder 43, thereby driving the piston rod of the telescopic cylinder 43 to continuously extend and retract. During the continuous extension and retraction, the piston rod of the telescopic cylinder 43, in conjunction with the transmission plate 44, drives the rotating shaft 46 to continuously rotate left and right, and the rotating shaft 46 drives the guide plate 45 to continuously swing left and right.

[0037] The foamed nylon elastomer to be crushed is introduced into the frame 41 through the feed inlet 48. The foamed nylon elastomer comes into contact with the constantly swinging guide plate 45. When the guide plate 45 swings to the left, the foamed nylon elastomer moves along the guide plate 45 to the left and enters the left end of the crusher body 1, where it comes into contact with the left end of the crushing roller. At this time, the left end of the crushing roller crushes the foamed nylon elastomer. When the guide plate 45 swings to the right, the foamed nylon elastomer comes into contact with the right end of the crushing roller, where the right end of the crushing roller crushes the foamed nylon elastomer.

[0038] Furthermore, when the foamed nylon elastomer slides down along the guide plate 45, it comes into contact with the rubber buffer head 492, which provides cushioning for the foamed nylon elastomer and reduces the noise generated by the collision between the foamed nylon elastomer and the inner wall of the frame 41.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
