Description

Technical Field

[0001] The invention relates to the technical field of wood waste recycling and processing, in particular to a pencil wood consumable waste recycling and processing system. Background Art

[0002] Wooden pencils are easy to carry, safe, sanitary, and feel good. They have always been popular and widely used. However, wooden pencils must be made of wood, and the wood consumed in the production of pencils is about one million acres of forest resources each year. As forests become increasingly scarce, ecological and environmental problems become increasingly prominent, and the concept of low-carbon and environmentally friendly life becomes more and more popular in society. Recycling and utilization of life and production methods are gaining more and more attention.

[0003] When processing a pencil, about half of the wood becomes sawdust. If it is discarded, a lot of resources will be wasted. Although there are some devices on the market that collect sawdust during processing, such as a pencil processing device and its use method with Chinese patent publication number CN117464773A, it includes "two symmetrically arranged first vertical plates and two symmetrically arranged second vertical plates, and the same set of conveying mechanisms are arranged between the two first vertical plates and the two second vertical plates; a storage barrel fixedly connected between the two first vertical plates for storing wood blocks; a feeding mechanism..." It can automatically clean the debris on the wood blocks and automatically collect the generated sawdust.

[0004] However, since the wood chip particles are small and light, they are relatively fluffy after being collected and are easy to splash. Therefore, the wood chips need to be squeezed, but the conventional squeezing device only presses down on the top. Although the upper and lower surfaces are compressed, due to the small size of the wood chip particles, wood chips will still leak out from the four sides, causing the compressed wood chip board to fall apart, which has certain defects. Based on the above problems, this case was born. Summary of the invention

DETAILED DESCRIPTION

[0024] The embodiment of the present invention provides a system for recycling and processing pencil wood consumable waste, such as Figure 1-5 As shown, it comprises a support 1, an outer cylinder 2, a side clamping mechanism 3, a plurality of pressing plates 4, an upper extrusion head 6, a lower extrusion head 7 and two sets of end clamping mechanisms 5. The outer cylinder 2 is suspended and fixed on the support 1.

[0025] In this embodiment, the number of the pressing plates 4 is six, but not limited to six, and may be four or more than six. The six pressing plates 4 are arranged in a circle inside the outer cylinder 2, and the middle of the six pressing plates 4 forms a hexagonal cavity. The side clamping mechanism 3 is arranged inside the outer cylinder 2, and is used to drive the six pressing plates 4 to be extruded synchronously toward the center. During the extrusion process, the cavity in the center of the six pressing plates 4 is always hexagonal. The upper and lower ends of the cavity between the six pressing plates 4 form an upper inlet 8 and a lower inlet 9. The upper inlet 8 is used to put in wood chips and squeeze the upper end of the wood chips, and the lower inlet 9 is used to squeeze the lower end of the wood chips and discharge the wood chip clumps.

[0026] like Figure 3-4 As shown, there are two groups of side clamping mechanisms 3, which are respectively arranged at the two ends of the outer cylinder 2 near the upper inlet 8 and the lower inlet 9. The side clamping mechanism 3 includes a fixed disk 32, a driving disk 35, six triangular guide blocks 31, four gears 40 and a motor 41. The fixed disk 32 is fixed at the center of the outer cylinder 2. The center of the fixed disk 32 is a hexagonal through groove that runs through from top to bottom. The outer edge of the pressure plate 4 slides along the edge of the through groove. The fixed disk 32 is provided with six guide rails 33 distributed at equal angles around its center. The six guide rails 33 are arranged in a hexagonal shape. The hypotenuses of the six triangular guide blocks 31 are abutted in sequence, and the upper inlet 8 is formed in the middle.

[0027] The six pressure plates 4 are respectively connected to the hypotenuses of the triangular guide blocks 31 which are abutted in sequence. A plurality of annular fixed sliders 38 are arranged in the outer cylinder 2. The driving disk 35 is provided with an annular groove 37 which is slidably fitted on the fixed slider 38. The bottom of the annular groove 37 extends outward in the radial direction. The end of the fixed slider 38 which is slidably fitted in the groove 37 is L-shaped, so that the fixed slider 38 can support the driving disk 35 and the driving disk 35 can rotate at the same time.

[0028] like Figure 3 As shown, six driving grooves 36 are annularly arranged on the driving disk 35, and the driving grooves 36 are inclined from the inside to the outside. A sliding shaft 34 is arranged in the middle of the tail of the triangular guide block 31, and the sliding shaft 34 passes through the upper and lower surfaces of the triangular guide block 31. The bottom of the sliding shaft 34 is slidably adapted in the guide rail 33, and the top of the sliding shaft 34 is slidably adapted in the driving groove 36.

[0029] When the driving disc 35 rotates, the driving groove 36 is displaced circumferentially, driving the slide post 34 to slide along the guide track 33, so that the triangular guide block 31 slides along the guide track 33 synchronously, thereby linking several pressing plates 4 to squeeze inward, making the hexagonal cavity gradually smaller, thereby compressing the wood chips inside.

[0030] like Figure 2 As shown, a gear ring 39 is provided on the outer ring of the driving disc 35, four gears 40 are fixed in the outer cylinder 2 through a gear seat and mesh with the gear ring 39, and the four gears 40 are arranged around the gear ring 39 in a planetary shape, and a motor 41 is provided on the outer cylinder 2 and coaxially connected with the gear 40. The driving disc 35 is driven to rotate by the motor 41.

[0031] The upper extrusion head 6 and the lower extrusion head 7 are both hexagonal structures communicating with the cavity.

[0032] like Figure 1 As shown, two sets of end clamping mechanisms 5 are arranged on the frame 1, and can respectively drive the upper extrusion head 6 and the lower extrusion head 7 to move horizontally and vertically. The upper extrusion head 6 and the lower extrusion head 7 correspond to the upper inlet 8 and the lower inlet 9 respectively. When the upper extrusion head 6 and the lower extrusion head 7 correspond vertically to the upper inlet 8 and the lower inlet 9, the end clamping mechanism 5 can drive them to move vertically. That is to say, in the initial state, the extrusion head is located in the horizontal direction above the outer cylinder 2, and then it is pushed horizontally to the inlet by the end clamping mechanism 5, and then the extrusion head will move vertically into the inlet for extrusion.

[0033] like Figure 1 As shown, the end clamping mechanism 5 includes a top plate 51, a horizontal driving plate 52, a hydraulic cylinder 53, a guide rail 54, a slider 55, two sets of connecting rods 56, and a horizontal slide 57. The horizontal slide 57 is fixedly arranged on the bracket 1 and is arranged horizontally along the entrance direction. Two side-by-side vertical slides 58 are arranged at the end of the horizontal slide 57. The guide rail 54 is arranged horizontally on the bracket 1. The slider 55 is slidably adapted on the guide rail 54. The hydraulic cylinder 53 is arranged horizontally and connected to the slider 55 through the driving plate 52. The hydraulic cylinder 53 is used to horizontally push the slider 55 to slide on the guide rail 54. The slider 55 is hinged to the top plate 51 through two parallel connecting rods 56. The distance between the two connecting rods 56 is the same as the distance between the two vertical slides 58. A pulley 59 is coaxially arranged on the hinge axis of the connecting rod 56 and the top plate 51, and the pulley 59 is slidably adapted on the horizontal slide 57 and the vertical slide 58. A groove for limiting the left and right deviation of the pulley 59 can be arranged on the horizontal slide 57 and the vertical slide 58. The upper extrusion head 6 and the lower extrusion head 7 are respectively arranged on the top plate 51 of the corresponding end clamping mechanism 5. The spacing between the guide rail 54 and the horizontal slide 57 is smaller than the length of the connecting rod 56. When the connecting rod 56 is in a vertical state, the depth of its bottom end is less than half of the vertical slide 58.

[0034] like Figure 1 As shown, since the extrusion head of a conventional extrusion device is located directly above the cavity, the extrusion head will affect the filling of the wood chips. The present device takes the upper extrusion head 6 as an example. In the non-extrusion state, the upper extrusion head 6 is located on the side close to the bracket 1. At this time, there is no obstruction above the cavity. At this time, the two connecting rods 56 are in an inclined state. When the hydraulic cylinder 53 pushes the upper extrusion head 6 to the square of the upper end entrance 8, the pulley 59 enters the vertical slide 58. When the hydraulic cylinder 53 continues to push, the pulley 59 will move vertically downward in the vertical slide 58, thereby driving the upper extrusion head 6 to vertically extrude the wood chips into the cavity.

[0035] Each vertical slide 58 is adapted to slide vertically with a lifting block 60, and the bottom of the lifting block 60 is connected to the bottom of the vertical slide 58 through a spring 61. When the hydraulic cylinder 53 is retracted and reset, the pulley 59 can be assisted to push out of the vertical slide 58 through the lifting block 60 and the spring 61.

[0036] Different from the above-mentioned embodiment, the lower extrusion head 7 is larger than the upper extrusion head 6. The lower extrusion head 7 can be used for supporting, that is, the size of the lower extrusion head 7 is larger than the cross section of the cavity. When filling wood chips, the end clamping mechanism 5 is used to drive the lower extrusion head 7 to the bottom of the pressing plate 4 to block the bottom of the cavity and prevent wood chips from leaking out.

[0037] A method for using a pencil wood consumable waste recycling and processing system:

[0038] Step 1: The upper extrusion head 6 is relocated away from the upper inlet 8, and the lower extrusion head 7 is pushed to the bottom of the six pressing plates 4 through the end clamping mechanism 5 below, so that it is supported at the bottom of the cavity.

[0039] Step 2: Fill the cavity with sawdust.

[0040] In step three, the side clamping mechanism 3 and the end clamping mechanism 5 driving the upper extrusion head 6 are clamped synchronously, and the six pressing plates 4 squeeze the periphery of the wood chips at the same time. The upper extrusion head 6 squeezes the top of the wood chips driven by the end clamping mechanism 5. When the extrusion is completed, the pulley 59 of the end clamping mechanism 5 located above is in the middle position of the vertical slide 58.

[0041] Step 4: the pressing plate 4 and the lower extrusion head 7 are reset.

[0042] Step 5: In order to prevent the wood chip mass from adhering to the pressing plate 4, the upper extrusion head 6 is continuously driven downward to push the wood chip mass out of the cavity.

[0043] Step six: the end clamping mechanism 5 drives the upper extrusion head 6 to reset.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
