Description

Technical Field

[0001] The utility model belongs to the technical field of wood-plastic board processing equipment, and in particular relates to a wood-plastic waste material processing device. Background Art

[0002] Wood plastic board is a new type of composite plastic mainly made of wood-based materials such as wood cellulose and plant cellulose, thermoplastic polymer materials, processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. At present, a large amount of debris will be generated during the processing of wood plastic boards, especially during grinding and polishing. The debris will be transported to the recycling bin through a conveying device and placed, and then a discharge port will be set at the lower end of the recycling bin for unloading and bagging, and the debris will be recycled or used. The transportation device generally extracts air from the transportation pipeline to form a negative pressure to transport the debris. However, when the debris is transported to the recycling bin by the transportation device, due to the small particles between the debris and the electrostatic adsorption caused by mutual friction, it is easy to form bridges and clusters in the recycling bin, so that when unloading and bagging in the recycling bin, there will be a situation where the material is not unloaded or the material is blocked.

[0003] The document with the authorization announcement number CN220074393U discloses a device for processing waste from the production of wood-plastic panels, including a recycling bin and a conveying pipe, wherein the recycling bin includes a feed bin and a pressure bin connected up and down, the conveying pipe is connected to the feed bin, a plurality of pressure units are evenly arranged in the pressure bin, and an exhaust hole is arranged on the recycling bin; wherein the pressure unit includes: a plurality of filter screens arranged in the pressure bin, the plurality of filter screens are interconnected to form a hollow filter part; an air pump is arranged outside the pressure bin. The device is arranged by the sub-bin arrangement of the recycling bin and the pressure unit is arranged in the pressure bin, so that the debris can enter the recycling bin, be adsorbed, and then blown off, which can effectively prevent the debris from bridging in the recycling bin and adsorbing each other to form a group.

[0004] However, the device still has the following problems: when the device needs to ensure the negative pressure effect in the pressure bin, it is necessary to ensure the sealing of the entire device and have high requirements for the precision of the device; it is also necessary to ensure that the volume of the pressure bin occupied by the powder is not too large, otherwise it will affect the negative pressure effect; moreover, when the negative pressure state is maintained in the pressure bin, the conveying pipe cannot deliver materials due to the disappearance of the pressure difference.

[0028] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms such as "setting" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] A wood-plastic waste processing device provided in this embodiment includes a feed bin 1 connected to a feed pipe 11, a discharge bin 2 communicated with the feed bin 1 and provided with a discharge structure 12 at the lower end, a stirring structure 3 arranged in the feed bin 1, and an intermittent unloading structure 4 arranged at the connection between the feed bin 1 and the discharge bin 2; the intermittent unloading structure 4 includes a partition 401 arranged at the connection between the feed bin 1 and the discharge bin 2, a discharge port 402 arranged on the partition 401, a rotating rod 403 rotatably connected to the lower surface of the partition 401, and a movable sealing plate 404 arranged at the end of the rotating rod 403 and used to close / open the discharge port 402.

[0030] It can be understood that the feed pipe 11 is a structure commonly used in the art to transport debris through negative pressure formed in the feed pipe 11 by a conveying device; the discharge structure 2 is the discharge device disclosed in the document CN220074393U described in the background technology, so it will not be repeated in this embodiment.

[0031] It is worth noting that, in order to avoid the accumulation of debris, the feed bin 1 and the discharge bin 2 are both cylindrical bodies without obvious dead corners inside, and in order to facilitate the unloading of materials, the discharge bin 2 presents an inverted truncated cone structure. The stirring structure 3 is used to stir the debris in the feed bin 1, the first purpose is to reduce the phenomenon of agglomeration and bridging, and the second purpose is to dissipate the heat of the debris by stirring to avoid excessive heat generated by accumulation.

[0032] It is worth noting that the partition 401 is a circular plate that closes the connection between the feed bin 1 and the discharge bin 2. There are at least two discharge ports 402, which are symmetrically arranged on both sides of the circular plate, and in order to avoid the problem of debris accumulation on the circular plate, the discharge port 402 is arranged on the edge of the circular plate. The shape of the discharge port 402 is preferably a circle without obvious dead angles. The shape of the movable sealing plate 404 corresponds to the discharge port 402. When the movable sealing plates 404 on both sides are rotated to fit the lower side of the discharge port 402 and completely cover the discharge port 402 by the driving of the rotating rod 403, the discharge port 402 can be closed. Continue to rotate the movable sealing plate 404, and the discharge port 402 is partially opened until it is fully opened. The above structure controls the speed and total amount of debris in the feed bin 1 entering the discharge bin 2 through the degree of opening of the discharge port 402, thereby avoiding the accumulation of debris in the feed bin 1 and avoiding agglomeration and bridging.

[0033] In this embodiment, the stirring structure 3 includes a rotating shaft 301 rotatably arranged in the feed bin 1, a stirring member 302 arranged on the rotating shaft 301, and a motor 303 arranged at the upper end of the feed bin 1 and used to drive the rotating shaft 301 to rotate. The stirring member 302 includes a plurality of frame-shaped stirring blades. Among them, the frame-shaped setting of the stirring member 302 can increase the stirring volume of the stirring member 302 and ensure the stirring effect. In addition, the frame-shaped setting can avoid debris from being trapped on the stirring member to the greatest extent, reducing the difficulty of cleaning the device.

[0034] In this embodiment, an opening is provided in the middle of the partition 401, and a bearing 401a is installed in the opening for connecting the rotating rod 403 and the rotating shaft 301 respectively. Furthermore, an inclined plate 401b is provided on the upper surface of the partition 401, which is inclined from the bearing 401a to the discharge port 402. The setting of the opening and the bearing can enable the driving shaft 301 to drive the rotating rod 403 to rotate through the bearing 401a, so that the intermittent unloading structure 4 does not need to add a power source, reduces the structure in the discharge bin 2, avoids the accumulation of debris, and reduces the difficulty of cleaning the device; the inclined plate 401b is provided to avoid the problem that debris accumulates at the center of the partition 401 and cannot enter the discharge bin 2.

[0035] As a further preferred embodiment of this embodiment, the intermittent material discharge structure 4 further includes an annular groove 405 provided on the lower surface of the partition plate 401, and a connecting block 406 provided on the upper surface of the rotating rod 403 and inserted into the annular groove 405. The connecting block 406 includes at least two blocks symmetrically provided on both sides of the rotating rod 403, and the blocks are slidably connected to the annular groove 405 to improve the stability of the rotating rod 403.

[0036] As a further preferred embodiment of the present invention, the intermittent unloading structure 4 further comprises an auxiliary stirring rod 407 disposed at the center of the lower end of the rotating rod 403 and located in the discharge bin 2. The auxiliary stirring rod 407 comprises a rod body 407a and a blade 407b disposed on the rod body 407a and shortened from top to bottom. The auxiliary stirring rod 407 is provided to further improve the flow effect of the debris in the discharge bin 2 and avoid material blocking, and the gradually shortened blade is provided to adapt to the inverted truncated cone structure of the discharge bin 2.

[0037] As a further preferred embodiment of the present invention, the intermittent material discharging structure 4 further comprises a ball bearing 408 disposed on the side end of the movable sealing plate 404 away from the rotating rod 403. The purpose of the ball bearing is to enhance the rotation stability of the movable sealing plate 404 and the tightness of the connection with the inner wall of the bin body, and to reduce the friction between the movable sealing plate 404 and the inner wall.

[0038] As a further preferred embodiment of the present invention, the stirring structure 3 further comprises bristles 304 disposed on the lower surface of the stirring member 302 and located at the upper end of the discharge port 402. The bristles 304 are deformable bristles under pressure, and they mainly play the function of cleaning the debris remaining at the discharge port 402 during the rotation of the stirring member 302.

[0039] The waste treatment device provided in this embodiment has the following advantages compared to the prior art: first, the internal structure of the device is simple and only requires one motor as a power source, which has low requirements for device precision and low economic cost; second, the device controls the waste entering the discharge bin to ensure that the discharge is not blocked, and can still work normally when the feed bin is fully loaded, which has the advantage of strong practicality.
