Description

Technical Field

[0001] This utility model relates to the field of wood shavings processing technology, specifically to a wood shavings conveying and spreading device. Background Art

[0002] There are many types of engineered wood products, among which particleboard boasts performance comparable to medium-density fiberboard (MDF) but at a lower cost, leading to its rapid development in my country. Because of its relatively uniform structure and good processing performance, particleboard can be processed into large-format boards as needed, making it a superior raw material for manufacturing furniture of various sizes and styles. Finished particleboard does not require further drying and can be used directly, exhibiting excellent sound absorption and insulation properties. Traditional particleboard is mainly divided into the following three types: 1) Log particleboard: such as pine or eucalyptus particleboard; 2) Agricultural by-product particleboard: such as bagasse particleboard, flax particleboard, cotton stalk particleboard, and bamboo particleboard; 3) Industrial material particleboard: such as cement particleboard and gypsum particleboard.

[0003] When processing wood shavings, a conveyor system is usually used for transportation. However, the shavings are usually fed onto the conveyor system manually, which can easily lead to uneven distribution or even accumulation of shavings. If the conveyor system transports the shavings to the next process, the shavings can easily accumulate at the entrance of the next process, requiring workers to frequently deal with the shavings accumulated at the entrance, which is inconvenient for the workers.

[0004] Therefore, we propose a shavings conveying fabric device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wood shavings conveying and feeding device, comprising a conveying platform and a drive shaft and a driven shaft respectively installed at both ends of the conveying platform. One end of the drive shaft is connected to a first motor installed on the conveying platform, and a conveyor belt for conveying wood shavings is driven and installed on the drive shaft and the driven shaft. Mounting frames are installed on both sides of the conveying platform, and mounting plates are installed on the mounting frames. A second motor is installed on one of the mounting plates, and the output shaft of the second motor is connected to a rotating shaft rotatably installed between the two mounting plates. A plurality of material-pushing plates for agitating the wood shavings are installed on the rotating shaft.

[0007] Furthermore: a lead screw is rotatably mounted on the upper part of the mounting bracket, and a threaded seat is threadedly mounted on the lower part of the lead screw. Support rods that are fixedly connected to the mounting plate are symmetrically mounted on the threaded seat.

[0008] Furthermore: a locking cylinder is fixed to the top of the mounting bracket, and a locking disc that is fixedly connected to the lead screw is rotatably installed inside the locking cylinder, and a wing bolt that mates with the locking disc is threaded onto the locking cylinder.

[0009] Furthermore, the inner wall of the mounting bracket is equipped with a slide rail along a straight direction, and the mounting plate is provided with a slide groove that cooperates with the slide rail.

[0010] Furthermore: a protective cover with openings at both the top and bottom is fixed between the two mounting plates. A cover plate is placed on the top of the protective cover, and a mounting bracket is detachably installed at the bottom of the protective cover. Baffles are symmetrically installed on the lower part of the mounting bracket.

[0011] Furthermore, a rubber protective plate is detachably installed at the bottom of the baffle, and the bottom of the protective plate is in contact with the outer surface of the conveyor belt.

[0012] Furthermore: a plurality of dragging components for dragging the conveyor belt are equidistantly installed on the top of the conveyor table. Each dragging component includes a first mounting seat and a second mounting seat symmetrically fixed on the top of the conveyor table, with two first mounting seats located between two second mounting seats. A first rotating roller for dragging the conveyor belt is rotatably installed between the two first mounting seats, and an inclined second rotating roller is rotatably installed between the first mounting seats and the second mounting seats.

[0013] Furthermore, a number of support components are equidistantly installed at the bottom of the conveyor platform. Each support component includes a third mounting seat symmetrically fixed to the bottom of the conveyor platform, and a third rotating roller for supporting the conveyor belt is installed between two of the third mounting seats.

[0014] The beneficial effects of this utility model are:

[0015] This invention features a second motor, a rotating shaft, and several material-pushing plates at the upper part of the conveyor belt. The second motor and the rotating shaft work together to drive the material-pushing plates to rotate, which in turn pushes the wood shavings on the conveyor belt, ensuring that the wood shavings are evenly distributed on the conveyor belt, facilitating subsequent processing of the wood shavings.

[0016] This utility model has a screw, a threaded seat, a support rod, and a mounting plate on the mounting frame. Through the cooperation of the screw, threaded seat, and support rod, the mounting plate can be driven to adjust its height. This allows the two mounting plates to drive several material feeding plates to adjust their height via a rotating shaft. The height of the material feeding plates can be adjusted according to the density of the wood shavings, thereby improving the effectiveness of the distribution device.

[0017] This utility model features a protective cover between two mounting plates, which reduces safety hazards and prevents workers from accidentally touching the material-pulling plate and causing injury, thereby improving worker safety.

DETAILED DESCRIPTION

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1As shown: A wood shavings conveying and spreading device includes a conveyor table 1. A drive shaft 2 and a driven shaft 3 are rotatably mounted at both ends of the conveyor table 1. One end of the drive shaft 2 is connected to a first motor 4 installed on the side of the conveyor table 1. The first motor 4 drives the drive shaft 2. The same conveyor belt 5 is driven and mounted on the drive shaft 2 and the driven shaft 3. After the wood shavings are placed on the upper part of the conveyor belt 5, the output shaft of the motor 4 can drive the drive shaft 2 to rotate. Through the cooperation of the drive shaft 2 and the driven shaft 3, the conveyor belt 5 can be driven to transmit power and convey the wood shavings.

[0027] like Figure 2 As shown: Several dragging components are equidistantly installed on the top of the conveyor table 1. Specifically, the dragging components are symmetrically installed on the first mounting base 241 and the second mounting base 242 on the top of the conveyor table 1, and the two first mounting bases 241 and the two second mounting bases 242 are located on the same straight line, with the two first mounting bases 241 located between the two second mounting bases 242. The same first rotating roller 243 is rotatably installed between the two first mounting bases 241. Through the setting of the first rotating roller 243, the upper part of the conveyor belt 5 can be dragged. A second rotating roller 244 is rotatably installed between the first mounting bases 241 and the second mounting bases 242. Through the setting of the second rotating roller 244, the upper edge of the conveyor belt 5 can be dragged, so that the conveying area of ​​the conveyor belt 5 is set in an "arc" shape, avoiding the situation that the wood shavings fall from both sides during the conveying process.

[0028] like Figure 2 As shown: Several support components are equidistantly installed at the bottom of the conveyor table 1. Specifically: The support components include third mounting bases 251 symmetrically fixed at the bottom of the conveyor table 1. A third rotating roller 252 is rotatably installed between the two third mounting bases 251, and the third rotating roller 252 is in contact with the lower part of the conveyor belt 5. The setting of the third rotating roller 252 plays the role of supporting the conveyor belt 5 and preventing the conveyor belt 5 from becoming loose during the conveying process.

[0029] Example 2

[0030] Although the above embodiment 1 can transport wood shavings to a designated location for subsequent processing, the feeding of wood shavings onto the conveyor 5 is usually done manually, which can easily lead to uneven distribution of wood shavings or even accumulation. If the wood shavings enter the next process, they can easily accumulate at the feed inlet of the next process. Therefore, in order to overcome the above-mentioned technical defects, improvements are made based on embodiment 1.

[0031] On both sides of the conveyor table 1, there are U-shaped mounting brackets 6. Each mounting bracket 6 has a lead screw 11 rotatably mounted on its top, and a rotating handwheel 27 is fixed on the top of the lead screw 11. The rotating handwheel 27 facilitates the rotation of the lead screw 11. A threaded seat 12 is threaded on the lower part of the lead screw 11, and support rods 13 are symmetrically fixed on the outer surface of the threaded seat 12. The bottom ends of the two support rods 13 are fixed on the same mounting plate 7. Rotating the lead screw 11 can drive the threaded seat 12 to move up and down, and the threaded seat 12 can drive the mounting plate 7 to move up and down through the support rods 13.

[0032] In detail: The top of the mounting bracket 6 is fixed with a locking cylinder 14, and a locking disc 15, which is fixedly connected to the lead screw 11, is rotatably installed inside the locking cylinder 14. It should be noted that: the outer surface of the locking disc 15 is provided with several locking holes (not shown in the figure) at equal intervals along the circumferential direction, and a wing bolt 16 is threaded on the locking cylinder 14. After one end of the wing bolt 16 is inserted into the interior of one of the locking holes, it plays the role of locking the lead screw 11 and preventing the device from falling off during use.

[0033] The two inner sidewalls of the mounting bracket 6 are each equipped with a slide rail 17 along a straight direction. The mounting plate 7 has a slide groove (not shown in the figure) on both sides. The mounting plate 7 is slidably mounted on the slide rail 17 through the slide groove. The cooperation between the slide groove and the slide rail 17 plays a role in limiting the position of the mounting plate 7 and preventing the mounting plate 7 from shaking during the up and down movement.

[0034] The two mounting plates 7 are rotatably mounted on the same rotating shaft 9. It should be noted that a bearing 26 is provided at the connection between the rotating shaft 9 and the mounting plate 7. The bearing 26 allows the rotating shaft 9 to rotate more smoothly on the mounting plate 7. One end of the rotating shaft 9 is connected to a second motor 8 fixed on the mounting plate 7. The second motor 8 drives the rotating shaft 9. Several material-pulling plates 10 are equidistantly mounted on the rotating shaft 9 along the circumferential direction. The material-pulling plates 10 can agitate the wood shavings on the conveyor belt 5, so that the wood shavings can be evenly distributed on the conveyor belt 5.

[0035] A protective cover 19 is fixed between the two mounting plates 7. If the material-pulling plate 10 is located inside the protective cover 19, the protective cover 19 can reduce safety hazards and prevent workers from accidentally touching the material-pulling plate 10 and causing injury. A ring plate 21 is detachably installed at the bottom of the protective cover 19 by bolts, and baffles 22 are installed on both sides of the ring plate 21. The baffles 22 serve a protective function to prevent shavings from falling off the conveyor belt 5 during the pulling process. A protective plate 23 is detachably installed at the lower part of the baffles 22 by bolts. The protective plate 23 is made of rubber material, and the lower part of the protective plate 23 is in contact with the outer surface of the conveyor belt 5. The protective plate 23 further protects the shavings and prevents them from falling off the conveyor belt 5.

[0036] Before use, the height of the feeding plate 10 can be adjusted according to the density of the wood shavings distribution.

[0037] When adjusting the height of the material feeding plate 10, two lead screws 11 are rotated simultaneously. The two lead screws 11 can drive the threaded seat 12 to move up and down. The threaded seat 12 can drive the mounting plate 7 to move up and down through the support rod 13. The two mounting plates 7 can drive the same rotating shaft 9 to move up and down. The rotating shaft 9 can drive several material feeding plates 10 to move up and down at the same time, so that the height of the material feeding plate 10 can be adjusted according to the requirements.

[0038] If the wood shavings on conveyor belt 5 are to be evenly distributed;

[0039] The conveyor belt 5 can drive the wood shavings to be conveyed (the principle of wood shavings conveying has been described in the above embodiment 1, and will not be described in detail in this embodiment). Then, the second motor 8 is turned on. The output shaft of the second motor 8 can drive the rotating shaft 9 to rotate. The rotating shaft 9 can drive several material-pulling plates 10 to rotate. Through the multiple material-pulling plates 10, the wood shavings on the conveyor belt 5 can be moved, so that the wood shavings can be evenly distributed on the conveyor belt 5.
