Description

Technical Field

[0001] This utility model relates to the field of material spreading machinery technology, and in particular to a wood shavings equalizer. Background Technology

[0002] Wood shavings are a commonly used material in the production of engineered wood products. They are produced by cutting wood blocks using equipment such as wood shaving machines. The shavings vary considerably in size and need to be screened after cutting for classification in subsequent production. Vibrating screens are a common device for screening wood shavings. They loosen the material through vibration, causing the shavings to move forward gradually. Smaller shavings are screened down, while larger ones are output from the screen outlet, achieving the screening purpose. In actual production, wood shavings are usually fed into the vibrating screen in a pile. Given the rough surface and numerous burrs of the shavings, the shavings tend to stick together. Relying solely on the vibration of the screen to loosen and spread them would waste a significant amount of screening stroke, resulting in poor screening efficiency. Therefore, the inventors added a material spreader at the input end of the vibrating screen to pre-spread the incoming wood shavings.

[0003] The feed homogenizer used is as follows Figure 6 As shown, it employs an auger structure that pushes the wood shavings to both sides, distributing them to the sides in advance so that they would otherwise pile up and fall onto the vibrating screen. However, because the bottom of the distributor is an open discharge port, the two auger structures cannot actually push the wood shavings a large distance to the sides, resulting in a less than ideal spreading effect. Therefore, the inventors further improved the distributor, leading to this invention. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a particle distribution device that improves the paving effect.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wood shavings equalizer, including a horizontally arranged equalizer cylinder, an inlet located at the middle of the upper part of the equalizer cylinder, and a discharge port extending the entire length of the lower part of the equalizer cylinder; an equalizer shaft is rotatably installed inside the equalizer cylinder, and two pushing screws with opposite spiral directions are fixedly arranged on the equalizer shaft, with the proximal ends of the two pushing screws located at the inlet; an extension baffle and an anti-fall baffle are respectively provided on the upstream and downstream sides of the discharge port of the equalizer cylinder, the extension baffle and the anti-fall baffle forming the equalizer discharge port, and the edge of the extension baffle at the equalizer discharge port is arranged obliquely, gradually approaching the anti-fall baffle along the pushing direction.

[0006] As a preferred technical solution, the edge of the anti-fall baffle located at the material discharge port is obliquely arranged so that it gradually moves away from the material extension baffle along the pushing direction.

[0007] As a preferred technical solution, the material stretching baffle includes a material stretching fixing section fixedly connected to the material equalization cylinder, a material stretching adjustment section is installed on the material stretching fixing section, and a material stretching side adjustment structure is provided between the material stretching adjustment section and the material stretching fixing section.

[0008] As a preferred technical solution, the material extension side adjustment structure includes a material extension side countersunk bolt disposed on the material extension fixing section. The material extension side countersunk bolt extends outward from the outer surface of the material extension fixing section. The material extension adjustment section is provided with a material extension side adjustment elongated hole corresponding to the material extension side countersunk bolt. A material extension side fastening nut is installed on the material extension side countersunk bolt at the outer side of the material extension adjustment section.

[0009] As a preferred technical solution, the end of the material extension adjustment section away from the material uniform discharge port is integrally bent with a material extension side operation section.

The edge of the extension baffle at the distribution outlet is obliquely positioned, gradually approaching the anti-fall baffle along the pushing direction. This invention adds the extension baffle at the discharge outlet, which slows down the rapid fall of wood shavings, thereby extending the pushing stroke to both sides. Ultimately, this allows the material entering from the inlet to form a more dispersed discharge at the longer distribution outlet, improving the paving effect. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0023] like Figure 1As shown, the wood shavings distributor includes a horizontally arranged distribution cylinder 1. The distribution cylinder 1 has a feed inlet 11 at its upper center and a full-length discharge outlet 12 at its lower part. A distribution shaft 2 is rotatably mounted inside the distribution cylinder 1, and extends out of the distribution cylinder 1 and is connected to a distribution driver 21. Two opposing spiral pusher screws 22 are fixedly mounted on the distribution shaft 2, with their proximal ends located at the feed inlet 11. A large volume of wood shavings continuously fed into the distribution cylinder 11 is spread to both sides under the action of the two pusher screws 22. The spread wood shavings then fall from the discharge outlet 12; conventionally, they fall directly onto the input end of the vibrating screen to achieve the spreading purpose. The above structural principle is easily understood by those skilled in the art based on existing technology and will not be elaborated further here.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, based on the above structural principle, the material distribution cylinder 1 is provided with a material extension baffle 3 and a fall prevention baffle 4 on the upstream and downstream sides of the material discharge port 12, respectively. The material extension baffle 3 and the fall prevention baffle 4 form a material distribution outlet 5. The edge of the material extension baffle 3 at the material distribution outlet 5 is obliquely arranged so that it gradually approaches the fall prevention baffle 4 along the pushing direction.

[0025] The pushing action of the pushing screw 22 is mainly achieved by utilizing the friction between the material and the cylinder wall. As the material distribution shaft 2 rotates, the spiral blades at the same circumferential position on the cylinder wall continuously change forward, thereby achieving an axial pushing effect. Under this main action, combined with the gravity of the material and the friction between the pushing screw 22 and the material, the shavings form a roughly large-pitch spiral trajectory within the material distribution cylinder 1.

[0026] Based on the above principle, in this embodiment, an extension baffle 3 is added to the upstream side of the rotating part of the material discharge port 12. This baffle acts as a barrier to the material near the feed port 11, preventing it from falling directly. Therefore, some of the material can be pushed further by the spiral force of the extension baffle 3, resulting in a longer pushing stroke. Ultimately, this allows the material continuously entering from the feed port 11 to form a more dispersed discharge at the longer material discharge port 5, improving the paving effect. Preferably, the extension baffle 3 is an arc-shaped plate adapted to the outer periphery of the pushing spiral 22.

[0027] The anti-fall baffle 4, located downstream of the rotating discharge port 12, reduces the amount of wood shavings falling directly from the space between adjacent spiral blades, especially those near the feed port 11. This encourages more wood shavings to be pushed by the pushing spiral 22 and fall from both sides, ensuring a smooth paving effect. Preferably, the anti-fall baffle 4 is an arc-shaped plate adapted to the outer periphery of the pushing spiral 22.

[0028] In this embodiment, the upstream and downstream rotating sides refer to the same position of the material discharge port 12. The side where the pushing screw 22 arrives is the upstream rotating side, and the side where the pushing screw 22 departs is the downstream rotating side. This definition can more clearly illustrate the structural positional relationship.

[0029] Preferably, the edge of the anti-fall baffle 4 at the material distribution outlet 5 is obliquely arranged so that it gradually moves away from the material extension baffle 3 along the pushing direction. This arrangement weakens the anti-fall effect on the downstream side in the pushing direction and causes the material distribution outlet 5 to form an opening of relatively fixed width, ensuring smooth material drop in all pushing directions, especially near the end of the pushing process, and preventing material squeezing and blockage.

[0030] Preferably, such as Figures 2 to 4 As shown, the material-extending baffle 3 includes a material-extending fixing section 31 fixedly connected to the material-equalizing cylinder 1. A material-extending adjusting section 32 is installed on the material-extending fixing section 31, and a material-extending side adjusting structure 33 is provided between the material-extending adjusting section 32 and the material-extending fixing section 31. Through this adjustability, the material-extending baffle 3 can achieve different material-blocking areas, facilitating matching with variations in the volume of different batches of wood chips and the input speed of wood chip production. For example, when the volume of individual wood chips in a batch is generally small or the input speed of wood chip production is low, the material-extending adjusting section 32 can be adjusted to extend further beyond the material-extending fixing section 31 to increase the material-blocking area, reduce the area of ​​the material-equalizing outlet 5, and allow the wood chips to be more smoothly pushed by the large lateral stroke, ensuring the paving effect.

[0031] Correspondingly, such as Figures 1 to 3 as well as Figure 5As shown, the anti-fall baffle 4 includes an anti-fall fixing section 41 fixedly connected to the material distribution cylinder 1. An anti-fall adjusting section 42 is installed on the anti-fall fixing section 41, and an anti-fall side adjusting structure 43 is provided between the anti-fall adjusting section 42 and the anti-fall fixing section 41. This adjustability, combined with the adjustability of the extending baffle 3, allows for better matching of this embodiment with different monomer volumes of wood shavings and different production input speeds. For example, when the monomer volume of this batch of wood shavings is generally small or the production input speed is low, the anti-fall adjusting section 42 can be adjusted to extend further beyond the anti-fall fixing section 41 to increase the anti-fall area, reduce the area of ​​the material distribution outlet 5, and allow the wood shavings to be more smoothly pushed by the large lateral stroke, ensuring the paving effect.

[0032] like Figure 4 As shown, the material-side adjustment structure 33 in this embodiment includes a material-side countersunk bolt 34 disposed on the material-side fixing section 31. The use of the countersunk bolt can prevent it from protruding from the inner surface of the material-side baffle 3 and avoid interference with the pushing screw 22. The material-side countersunk bolt 34 extends outward from the outer side of the material-side fixing section 31. The material-side adjustment section 32 is provided with a material-side adjustment elongated hole 35 corresponding to the material-side countersunk bolt 34. A material-side fastening nut 36 is installed on the material-side countersunk bolt 34 at the outer side of the material-side adjustment section 32.

[0033] After confirming the condition of the wood shavings or its production input speed, when adjusting the elongated baffle 3, first loosen the elongated side fastening nut 36 to allow the elongated adjustment section 32 to move. Based on the guiding effect of the elongated adjustment hole 35 and the countersunk bolt 34 on the elongated side, it can only move in its own arc direction. By moving in this arc direction, different extension lengths relative to the elongated fixed section 31 are achieved, thus changing the material-blocking area of ​​the elongated baffle 3. After adjustment, retighten the elongated side fastening nut 36.

[0034] Preferably, such as Figure 3 As shown, the material extension adjustment section 32 has an integrally bent material extension side operation section 37 at one end away from the material distribution outlet 5, so as to facilitate the operation of the material extension adjustment section 32 during the adjustment process.

[0035] like Figure 5As shown, the fall-prevention side adjustment structure 43 in this embodiment includes a fall-prevention side countersunk bolt 44 disposed on the fall-prevention fixing section 41. The fall-prevention side countersunk bolt 44 extends outward from the outer side of the fall-prevention fixing section 41. The fall-prevention adjustment section 42 is provided with a fall-prevention side adjustment elongated hole 45 corresponding to the fall-prevention side countersunk bolt 44. A fall-prevention side fastening nut 46 is installed on the fall-prevention side countersunk bolt 44 at the outer side of the fall-prevention adjustment section 42. The adjustment method of the fall-prevention baffle 4 is the same as that of the material-extending baffle 3, and will not be described again here. Of course, as... Figure 3 As shown, the anti-fall adjustment section 42 has an integrally bent anti-fall side operation section 47 at the end away from the material discharge port 5 to facilitate adjustment operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
