Description

Technical Field

[0001] This utility model relates to the field of PE wood-plastic processing technology, and in particular to a feeding device. Background Technology

[0002] Wood-plastic composite (WPC), as a green, environmentally friendly, and high-performance new building material, has been widely used in outdoor landscaping and construction. PE wood-plastic raw materials, with polyethylene (PE) as the matrix, have also been widely adopted due to their excellent water resistance, impact resistance, and environmental friendliness. The initial and crucial process in the production of PE wood-plastic raw materials is the pretreatment and precise batching of raw materials, involving the feeding and mixing of wood flour, recycled PE plastic granules, talc, compatibilizers, and various other functional additives. Currently, the industry mainly uses two feeding methods: traditional small-bag manual feeding and semi-automatic ton-bag feeding station methods.

[0003] However, the two existing feeding methods have many shortcomings. Specifically, in the traditional small-bag manual feeding mode, most small and medium-sized production enterprises still generally use small packages of raw materials of 25 kg / bag. In the production process, they rely on manual labor to unpack, unpack, and transport the materials and pour them into the mixing machine. This results in high labor costs, high labor intensity, slow feeding speed, which restricts overall production capacity and low production efficiency. In addition, during the unpacking and pouring process, lightweight powders such as wood flour will generate dust pollution, and the dust will permeate the work site, causing environmental protection indicators to fail to meet standards. In the semi-automatic ton bag feeding station mode, it is usually a simple open or semi-open structure. In actual operation, at the moment the ton bag unloading port is opened and during the shaking process, the compressed powder is suddenly released, forming a strong dust jet. The dust generated far exceeds the environmental protection standards, polluting the environment inside and outside the workshop and posing a threat to the health of the workers.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0023] Reference Figures 1 to 4 As shown, this utility model discloses a feeding device for use in conjunction with a transfer device 10 to feed materials. In this embodiment, the material to be fed 11 is a ton bag.

[0024] The feeding device includes a frame 1, on which an isolation cover 20 is installed to isolate the dust generated during the feeding process and avoid polluting the working environment. In detail, the isolation cover 20 is provided with an openable and closable door assembly 21. The material to be fed 11 moves under the drive of the transfer device 10. When the door assembly 21 is opened, the material to be fed 11 can enter the isolation cover 20. The top of the isolation cover 20 has an opening to allow the transfer device 10 to pass through.

[0025] The feeding device further includes a feeding unit, which includes a feeding box 30 and a vibration component 31. The feeding box 30 is elastically connected to the frame 1, so that the feeding box 30 has redundancy in both the horizontal and vertical directions.

[0026] Specifically, the feeding box 30 is located at the bottom of the isolation cover 20, and the feeding box 30 is connected to the isolation cover 20; The top of the feeding box 30 is provided with a feeding port, through which the material to be fed 11 enters the feeding box 30. The bottom of the feeding box 30 is provided with a discharge port 301. The vibration component 31 is connected to the feeding box 30. When the vibration component 31 is working, it can drive the feeding box 30 to vibrate, thereby promoting the vibration discharge of the material in the feeding box 30. With this configuration, the isolation cover 20 and the feeding box 30 can cooperate to form a basically closed structure.

[0027] In addition, the feeding device also includes a dust removal unit 4, which is installed in the isolation cover 20 and communicates with the interior of the isolation cover 20. During the feeding process of the material to be fed 11, a large amount of dust will be generated in the isolation cover 20. The dust removal unit 4 absorbs the dust in the isolation cover 20 and sends it back into the feeding box 30, thereby making the feeding more thorough. On the one hand, it can prevent the accumulation of dusty materials in the isolation cover 20, and on the other hand, it can accelerate the feeding speed and improve the feeding efficiency.

[0028] It should be noted that the feeding device also includes a control unit, which is communicatively connected to the feeding unit and the dust removal unit 4 to output control signals to the feeding unit and the dust removal unit 4, thereby controlling the operation of the feeding unit and the dust removal unit 4.

[0029] At work, First, the raw materials for granulation, such as wood flour, plastic and talc powder, as well as the crushed material in ton bags, are fed into a large silo for storage via an elevator or negative pressure suction. After the trolley carries the material to be fed 11 into the feeding device, the door assembly 21 closes to ensure that the inside is sealed. The vibration assembly 31 vibrates to drive the feeding box 30 to sway up and down and left and right, thereby effectively driving materials with poor flowability such as wood powder to flow downward. Since the entire cover is sealed on all four sides and is equipped with a dust removal unit 4, the dust generated during the feeding process will be absorbed by the dust removal unit 4 and flow back into the feeding box 30.

[0030] Therefore, it can be understood that the feeding device protected by this utility model includes a frame, an isolation cover, a feeding unit, and a control unit. The isolation cover is fixed to the frame as a whole. The isolation cover, together with the feeding box, forms a sealed space. The feeding box is elastically connected to the frame. With the help of the vibration component, it can effectively ensure that the ton bag of material shakes in the feeding box, causing the material to vibrate downwards. Through the dust removal unit, the dust inside the isolation cover can be extracted and flow into the feeding box. As the material is conveyed to the next hopper, the feeding device of this utility model can effectively improve the on-site operating environment, effectively reduce dust overflow, avoid negative impacts on the health of operators, effectively improve the production efficiency of feeding, and reduce labor costs.

[0031] In detail, the frame 1 is also provided with a sealing plate assembly 12, which includes a front side plate, a rear side plate, a left side plate and a right side plate that are detachably arranged along the circumference of the frame 1, wherein the front side plate and the rear side plate are opposite to each other, and the left side plate and the right side plate are opposite to each other.

[0032] In this embodiment, the transfer device 10 is a crane, which transfers the material to be delivered 11 to a designated location. Of course, in other embodiments, the transfer device may also be other mobile devices.

[0033] Furthermore, the door assembly 21 includes a door body 210, a drive component 211, and a connecting seat. The drive component 211 is mounted on the isolation cover 20 via the connecting seat. The door body 210 is connected to the output end of the drive component 211 to open or close under the drive of the drive component 211. Preferably, the drive component 211 is a drive cylinder.

The flower plate 48, the cover plate 49, the support frame 46, and the cloth bag 47 are housed in the outer shell 41. The flower plate 48 is installed on the outer shell 41 and the cover plate 49 by fastening bolts. The support frame 46 is installed on the flower plate 48. The cloth bag 47 is sleeved on the support frame 46 and is connected to the hole of the flower plate 48. The fan 40 is installed on the top of the outer shell and is connected to the isolation cover 20 to extract dust from the isolation cover 20 and allow the dust to enter the filter bag 47 for temporary collection. Then, pulse vibration is applied to the filter bag 47 through the pulse valve 43, so that the dust in the filter bag 47 re-enters the feeding box 30, thereby achieving efficient absorption and discharge of dust in the isolation cover 20.

[0037] In order to facilitate the movement of materials, the feeding device is also provided with a guide plate 32, which is inclinedly arranged on the inner wall of the isolation cover 20 and is connected to the upper opening of the feeding box 30.

[0038] In detail, it also includes a guide cloth 33, an upper pressure plate 34 and a lower pressure plate 35.

This arrangement allows the first opening 2011 to provide space for the movement of the crane wire rope, and the brush 2012 also filters dust. It should be noted that the first opening 2011 is the clearance opening.

[0041] Furthermore, the frame 1 is provided with an elastic element 13, and the feeding box 30 is installed on the frame 1 through the elastic element 13; the elastic deformation direction of the elastic element 13 is consistent with the height direction.
