Description

Technical Field

[0001] The utility model relates to the technical field of wood recycling equipment, in particular to a device for recycling wood scraps. Background Art

[0002] Scraps refer to the reasonable remaining waste, broken materials and offcuts that are not completely consumed during the production process of manufacturing products within the originally planned and designed production raw materials and cannot be used to process the finished products under this product item. Generally also known as "leftover materials", scraps generally refer to flat plates and profiles. If these scraps are thrown away, it will cause a large amount of resource waste. We can recycle them. Before recycling these scraps, they need to be crushed and then granulated again. However, there are a few scraps that are completely broken, and they need to be manually screened from the rotating cylinder base and then crushed again later, and the operation is relatively complicated.

[0003] To solve the above problems, this case came into being. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a device for recycling wood scraps, which solves the problems raised in the above background art.

[0006] (2) Technical Solutions

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: A device for recycling wood scraps, including a frame. There is a feeding hopper at the top of the frame and a discharge port at the lower part. A crushing mechanism is arranged inside the frame, and its upper and lower sides are respectively connected to the feeding hopper and the discharge port. The crushing mechanism includes a rotating cylinder base. One side of the rotating cylinder base is pivotally connected to the side wall of the frame and is driven to rotate by a motor. The other side of the rotating cylinder base is penetrated, and a crushing wheel is arranged inside. Its characteristics are that: An opening corresponding to the position of the feeding hopper is opened above the rotating cylinder base, and an opening is also arranged below the opposite opening and a filter screen is arranged. The rotating shaft of the crushing wheel is pivotally connected to the inner wall of the other side of the frame and is independent of the rotating cylinder base.

[0008] Preferably, the bottom of the rotating cylinder base shrinks inward to form a buffer space extending downward, and the filter screen is located at the bottom of the buffer space.

[0009] Preferably, the rotation angle of the rotating cylinder base is 120 - 180°.

[0010] Preferably, after the rotating cylinder base rotates to a preset angle, it quickly returns to its original position, or starts the motor driving the crushing wheel after returning to its original position, so as to prevent the wood scraps from falling out directly without being filtered.

[0011] Furthermore, since the rotating cylinder base needs to rotate as a whole, the outer wall of the downward-extending buffer space needs to be within its circumferential virtual line to avoid rotational jamming problems.

[0012] (III) Beneficial Effects

[0013] After adopting the above technical solution, compared with the prior art, the present utility model has the following advantages: The present utility model is a device for recycling wood scraps. The rotating shaft of the crushing wheel is pivotally connected to the inner wall on the other side of the frame and is independent of the rotating cylinder base. The operation of the crushing wheel can be driven by a motor separately to complete the crushing operation. Finally, the wood that has not been filtered above the filter screen is inverted upward, and the wood is inverted to the side of the crushing wheel for secondary crushing, making the crushing more complete and avoiding subsequent manual screening operations.

[0019] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0020] As Figure 1 shown: A device for recycling wood scraps includes a frame 1. A feed hopper 2 is provided at the top of the frame 1, and a discharge port is provided at the lower part. A crushing mechanism is provided inside the frame 1, and the upper and lower sides thereof are respectively connected to the feed hopper 2 and the discharge port.

[0021] As Figures 2 - 3As shown in the figure: The crushing mechanism includes a rotating cylinder base 4. One side of the rotating cylinder base 4 is pivotally connected to the side wall of the frame 1 and is driven to rotate by a motor 5. The other side of the rotating cylinder base 4 is penetrated, and a crushing wheel 6 is arranged inside. Normally, an opening 7 corresponding to the position of the feeding hopper 2 is opened above the rotating cylinder base 4. An opening 7 is also arranged below the opening 7, and a filter screen 8 is arranged. After the wood scraps enter the upper opening 7 from the feeding hopper 2, they are crushed by the crushing wheel 6 and then reach the filter screen 8. The filtered scraps are collected (the collected shredded wood is used for subsequent secondary processing, such as composite wood board operations).

[0022] There are a few of the filtered scraps that are completely crushed and need to be manually screened out from the rotating cylinder base 4 and then crushed again later, and the operation is relatively complex. Therefore, in this embodiment, the design of the rotating cylinder base 4 realizes automatic secondary crushing.

[0023] As shown in the appendix Figure 3 As shown in the figure, the rotating shaft 9 of the crushing wheel 6 is pivotally connected to the inner wall of the other side of the frame 1 and is independent of the rotating cylinder base 4. The operation of the crushing wheel 6 can be driven by an external motor to complete the crushing operation. A rotating block 11 is arranged on one side of the rotating cylinder base 4. The rotating cylinder base 4 drives the rotating block 11 through the motor 5 to complete the rotation, so that the unfiltered wood on the upper side of the filter screen 8 is inverted upwards, and the wood is inverted to the side of the crushing wheel 6 for secondary crushing.

[0024] During the rotation of the rotating cylinder base 4, the wood will slide down due to the internal friction being less than the gravity. Therefore, the bottom of the rotating cylinder base 4 shrinks inward and forms a downward-extending buffer space 10. As shown in the appendix Figure 4 As shown in the figure, the unfiltered wood on the upper side of the filter screen 8 enters a buffer space 10 to prevent the wood from not being inverted to the upper side of the crushing wheel 6 during the rotation. Secondly, it should be noted that the rotation angle of the rotating cylinder base 4 is about 120 - 180°, and it only needs to rotate to export the unfiltered wood. Due to the existence of the buffer space 10, it is impossible to smoothly pour out the internal wood when it exceeds 90°. Therefore, the minimum angle of 120° is preferably taken, and all the internal wood can be exported at 180°.

[0025] Since the rotating cylinder base 4 needs to rotate as a whole, the outer wall of the downward-extending buffer space 10 needs to be within its circumferential virtual line to avoid the problem of rotational jamming.

[0026] Furthermore, after the rotating cylinder base 4 rotates, it needs to quickly return to its original position, or start the motor 5 that drives the crushing wheel 6 after returning to its original position, to prevent the wood scraps from falling out directly without being filtered.

[0027] The above is based on the embodiment as an inspiration. Through the above description, relevant staff can completely make various changes and modifications without departing from the idea of this invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
