Description

Technical Field

[0001] This invention belongs to the field of particleboard production technology, specifically relating to a reciprocating belt feeding mechanism for particleboard production. Background Technology

[0002] A reciprocating belt feeding mechanism is a device used to evenly spread wood shavings on a slab forming machine. The reciprocating belt conveys and evenly distributes the wood shavings on the moving belt or mesh belt of the forming machine to form a uniform wood shaving layer, which is then pressed into particleboard. It is an important component of the particleboard production line, and its performance and stability directly affect the quality of the particleboard. The reciprocating belt feeding mechanism can ensure that the wood shavings are evenly distributed on the entire slab surface, avoiding local areas that are too thick or too thin. It is usually matched with the continuous operation process of the particleboard production line to achieve high-efficiency production.

[0003] In actual production, during the feeding process of reciprocating belt feeding mechanisms, wood shavings inevitably fall from both sides of the conveyor belt, spreading throughout the production workshop and deteriorating the production environment. This not only increases the workload of cleaning but also seriously endangers the health of workers. Furthermore, the leakage leads to significant material contamination and loss, requiring reprocessing before reuse, greatly increasing production costs. Therefore, the leakage and recycling problems of reciprocating belt feeding mechanisms urgently need to be solved.

[0004] Therefore, in view of the above-mentioned shortcomings, this application proposes a reciprocating belt feeding mechanism for sheet metal production that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a reciprocating belt feeding mechanism for sheet metal production, thereby effectively solving the problems existing in the prior art.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0007] A reciprocating belt feeding mechanism for sheet metal production includes a frame, on which a feeding device is fixedly mounted. Horizontal circulating transmission chain devices are symmetrically arranged on both sides of the feeding device. A material spreading platform is located below the feeding device, and a reciprocating belt device is slidably mounted on the spreading platform. The reciprocating belt device is connected to the circulating transmission chain device. Material baffles are symmetrically arranged at the left and right ends of the spreading platform. Pushing devices are symmetrically arranged on the front and rear sides of the material baffles. A middle partition is arranged between the pushing devices in the left and right directions. A recycling device is connected between the middle partitions. The recycling device can recover and reuse leaked material near the middle partitions, avoiding pollution of the production workshop and material loss.

[0008] As a further provision of the above solution, the feeding device includes a feeding box, which is fixedly installed on the upper end of the frame. A feeding port is provided at the center of the upper surface of the feeding box. The circulating transmission chain device includes a rotating roller and a first motor. The rotating roller is rotatably connected to the front and rear sides of the feeding box. The first motor is fixedly installed on the side of the frame. A drive wheel is fixedly connected to the output shaft of the first motor. The axes of the drive wheel and the rotating roller are located on the same horizontal line. A transmission chain is connected to the drive wheel and the rotating roller. The first motor drives the drive wheel to rotate, and the drive wheel, in conjunction with the rotating roller, drives the transmission chain to rotate cyclically.

[0009] As a further feature of the above solution, the material spreading platform device includes a material spreading platform, which is parallel to the feeding box. A material spreading groove that runs through the left and right sides is opened on the upper surface of the material spreading platform. The material spreading groove is located directly below the feeding box. Slide rails are symmetrically arranged on the upper ends of the front and rear sides of the material spreading platform. A material receiving groove is opened between the slide rails and the material spreading groove.

[0010] As a further feature of the above solution, the intermediate partition device includes an intermediate partition, which is fixedly installed in the middle of the receiving trough. The intermediate partition is perpendicular to the receiving trough and symmetrically divides the receiving trough into left and right parts. A vent hole is opened at the center of the intermediate partition, which connects the left and right spaces of the receiving trough. Vertical sealing baffles are fixedly connected to the upper end of the left and right end faces of the intermediate partition.

[0011] As a further provision of the above scheme, the recycling device includes a recycling box, which is fixedly installed at the center of the lower end face of the material spreading platform device. The recycling box is equipped with a first pressure pump and a second pressure pump. A first suction pipe is connected to the first pressure pump, and the first suction pipe is simultaneously connected to the material receiving troughs on both sides. The connection point between the first suction pipe and the material receiving trough is located on the left side of the middle partition and below the sealing baffle. A second suction pipe is connected to the second pressure pump, and the second suction pipe is simultaneously connected to the material receiving troughs on both sides. The connection point between the second suction pipe and the material receiving trough is located on the right side of the middle partition and below the sealing baffle.

[0012] As a further provision of the above solution, the reciprocating belt device includes a transmission bracket and a reciprocating belt. The reciprocating belt is rotatably connected to the inner side of the transmission bracket. A second motor is fixedly connected to one end of the transmission bracket. The second motor is connected to the rotating shaft of the reciprocating belt. Slides are symmetrically arranged on the front and rear outer surfaces of the transmission bracket. The slides are slidably connected to the slide rails. Transmission teeth are provided on the upper surface of the transmission bracket. The transmission teeth are connected to the transmission chain. Mounting plates are fixedly connected to the left and right ends of the transmission bracket.

[0013] As a further provision of the above solution, the baffle plate device includes a baffle vertical plate, which is vertically fixedly connected to the mounting plate. The baffle vertical plate slides in contact with the material spreading trough. A scraping elastic plate is fixedly connected to the upper end of the baffle vertical plate. The scraping elastic plate slides against the reciprocating belt. The baffle vertical plate moves left and right with the transmission bracket to process the material in the material spreading trough. The scraping elastic plate cleans the reciprocating belt to prevent the material from moving above the reciprocating belt.

[0014] As a further provision of the above scheme, the pushing device includes a support plate and a pushing plate. The support plate is vertically fixed on the mounting plate, located directly above the receiving trough with its lower end extending into the receiving trough. A vertical spring column is provided at the center of the pushing plate, and a limiting platform is provided at the other end of the spring column. A buffer spring is sleeved on the spring column, and the spring column is slidably connected to the support plate. The buffer spring is located between the support plate and the pushing plate. A guide rod parallel to the spring column is provided on the support plate, and the guide rod is slidably connected to the support plate. The pushing plate is perpendicular to the receiving trough and slidably contacts it.

[0015] The beneficial effects of this invention are:

[0016] When the equipment is working, the material falls into the receiving trough from both sides of the reciprocating belt device. The pushing device pushes the material in the receiving trough towards the middle partition device. When the reciprocating belt device moves to its left or right limit position, the pushing plate and the sealing baffle on one side, under the action of the buffer spring, form a sealed space with the inner wall of the receiving trough and the middle partition. The leaked material is located in this sealed space. The pushing plate on the other side moves away from the sealing baffle, and the receiving trough on this side is in an open state. The corresponding first pressure pump or second pressure pump is started, and the material in the receiving trough is recovered through the first suction pipe or second suction pipe. The vent ensures stable air pressure and is conducive to the recovery of material between the pushing plate and the sealing baffle on the other side.

[0017] By opening material collection troughs on both sides of the material distribution platform and setting material pushing devices at both ends of the reciprocating belt device, the circulating transmission chain device drives the reciprocating belt device to move back and forth, and the material pushing device moves back and forth in the material collection trough simultaneously. In conjunction with the recycling device, the material is automatically collected and recycled, improving the material recycling efficiency and cleaning effect, solving the pollution and loss problems caused by material leakage, improving the working environment of workers, and reducing production costs.

[0032] like Figure 3 , Figure 4 As shown, the material spreading platform device 3 includes a material spreading platform 301, which is parallel to the feeding box 201.

[0034] like Figure 7 As shown, the reciprocating belt device 5 includes a transmission bracket 504 and a reciprocating belt 502. The reciprocating belt 502 is rotatably connected to the inner side of the transmission bracket 501. A second motor 505 is fixedly connected to one end of the transmission bracket 501. The second motor 505 is connected to the rotating shaft of the reciprocating belt 502. Slide tables 503 are symmetrically arranged on the front and rear outer surfaces of the transmission bracket 501. The slide tables 503 are slidably connected to the slide rails 303.

[0035] like Figure 8 , Figure 9 As shown, the baffle plate device 6 includes a baffle vertical plate 601, which is vertically fixed to the mounting plate 506. The baffle vertical plate 601 slides in contact with the material spreading trough 302. A scraping elastic plate 602 is fixedly connected to the upper end of the baffle vertical plate 601. The scraping elastic plate 602 slides against the reciprocating belt 502. The baffle vertical plate 601 moves left and right with the transmission bracket 501 to process the material in the material spreading trough 302.

The pushing device 7 includes a bracket plate 701 and a pushing plate 702. The bracket plate 701 is vertically fixed.

Push plate 702 is perpendicular to and slidably connected to receiving trough 304.

[0036] The working principle of this invention is as follows: The first motor 403 drives the drive wheel 404 to rotate. The drive wheel 404, in conjunction with the rotating roller 401, drives the transmission chain 402 to rotate cyclically. The transmission chain 402, through the transmission teeth 504, drives the transmission bracket 501 to move on the slide rail 303 via the slide table 503. This realizes that the cyclic transmission chain device 4 drives the reciprocating belt device 5 to move back and forth. The pushing device 7 moves back and forth synchronously in the receiving trough 304. When adding or spreading material, the material falls from both sides of the reciprocating belt device 5 into the receiving trough 304, and the material is always located between the two pushing plates 702 to prevent further leakage. When the reciprocating belt device 5 moves to the right, the two support plates 701 on the left push the pushing plate 702 to the right and closer to the middle partition 901, pushing the material in the receiving trough 304 towards the middle partition 901. When the reciprocating belt device 5 moves to the right limit position, the pusher plate 702 and the sealing baffle 903, under the action of the buffer spring 7031, form a sealed space with the inner wall of the receiving trough 304 and the middle partition 901. The leaked material is concentrated in this sealed space. The pusher plate 702 and the sealing baffle 903 on the other side move away from each other, and the receiving trough 304 on this side is in an open state. The corresponding first pressure pump 802 is started, and the material in the receiving trough 304 on the left side of the middle partition 901 is recovered through the first suction pipe 804. The vent 902 ensures stable air pressure, and the airflow direction is conducive to the recovery of material between the pusher plate 702 and the sealing baffle 903 on the other side. The operation of the reciprocating belt device 5 when it moves to the left is the same as the above process, and the leaked material is cleaned up and recovered synchronously, in a timely manner and thoroughly.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the scope of the invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
