Description

Technical Field

[0001] This utility model relates to the technical field of particleboard production equipment, specifically to a feeding device for a particleboard core layer adhesive mixing machine. Background Technology

[0002] In the particleboard gluing process, the glue mixer needs to apply glue evenly to the core layer of wood shavings. Since the raw materials mostly come from bamboo and wood processing residues, the wood shavings often contain magnetic impurities such as iron nails and metal shavings. If such foreign objects enter the glue mixer along with the material, they can easily cause equipment failures such as the mixing paddle breaking and bearing jamming.

[0003] To address this issue, patent CN208290120U proposes a feeding system for a particleboard core layer adhesive mixer. This system incorporates a magnetic strip at the feed pipe of the feeding device, utilizing magnetic adsorption to intercept metallic foreign objects and prevent them from entering the mixer and damaging the mixing components. However, this design has significant drawbacks: after prolonged use, the accumulated metallic impurities on the surface of the magnetic strip require manual cleaning. This necessitates stopping the machine to disassemble the magnetic strip, causing production line interruptions and impacting efficiency. Especially in continuous production, frequent shutdowns not only increase time costs but may also lead to decreased equipment sealing due to repeated disassembly and reassembly, exacerbating the risk of dust leakage.

[0004] Therefore, developing a self-cleaning, continuously operating feeding device for particleboard core layer adhesive mixing machine has become a key technological requirement for improving the automation level of particleboard production lines. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a feeding device for a particleboard core layer adhesive mixing machine, so as to solve the problem that the existing technology uses magnetic sheets to adsorb metal impurities in particleboard, and the machine needs to be stopped and disassembled when cleaning the magnetic sheets, which leads to production interruption.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A feeding device for a particleboard core layer adhesive mixing machine includes a feeding pipe, a magnetic roller, a scraper, and a spring; a feeding pipe is provided on one side of the feeding pipe, and a guide groove is provided on the other side of the feeding pipe; the magnetic roller and the scraper are rotatably connected inside the feeding pipe; the magnetic roller can adsorb metal impurities often mixed in with the particleboard; one end of the scraper is connected to the feeding pipe through the spring, so that the other end of the scraper is in close contact with the surface of the magnetic roller under the action of the spring force.

[0008] As a further embodiment of this utility model: one end of the guide channel is connected to the inside of the feeding pipe, and the other end of the guide channel extends downward at an angle.

[0009] As a further embodiment of this utility model, the magnetic roller is a cylindrical hollow roller body with multiple circumferentially arranged strip-shaped permanent magnets embedded on its surface.

[0010] As a further embodiment of this utility model, the magnetic roller is connected to the inner wall of the feeding pipe at both ends in a counterclockwise rotation.

[0011] As a further embodiment of this utility model: the scraper is L-shaped, with one straight side connected to the feeding pipe via a spring, and the other straight side in close contact with the top surface of the magnetic roller.

[0012] As a further embodiment of this utility model, it also includes a limiting tube, a nut, and a handle screw; the limiting tube is fixedly connected to the outer wall of the feeding pipe; the nut is disposed inside the limiting tube, its shape and size are adapted to the inner hole of the limiting tube, and it is connected to the spring; the shank end of the handle screw is threadedly connected to the nut, and the shank end of the handle screw abuts against the limiting tube under the tension of the spring.

[0013] As a further improvement of this utility model, the upper edge of the straight edge of the scraper that is in close contact with the top surface of the magnetic roller is chamfered.

[0014] By adopting the above technical solution, this utility model will have the following beneficial effects:

[0015] This utility model provides a feeding device for a particleboard core layer adhesive mixing machine. A magnetic roller adsorbs metal impurities from the particleboard output from one feeding pipe and moves them to the other side. Because the scraper is pressed tightly against the top surface of the magnetic roller under the action of a spring, these metal impurities can be peeled off the magnetic roller and collected along the scraper discharge channel. During the peeling process, the elastic deformation of the spring absorbs positional deviations on the surface of the magnetic roller, preventing rigid collisions that could damage the scraper or the magnetic roller.

[0016] Compared with existing technologies that require disassembling the magnet to clean metal impurities, this invention uses a magnetic roller and scraper to automatically clean the metal impurities adsorbed from the wood shavings, ensuring continuous production and improving production efficiency.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the following description is to be considered exemplary in nature and not restrictive.

[0023] Please refer to Figure 1 and Figure 2 In one embodiment of the feeding device of the particleboard core layer adhesive mixer 8 of this utility model, the feeding device of the particleboard core layer adhesive mixer 8 includes a feeding pipe 1, a magnetic roller 2, a scraper 3, and a spring 4:

[0024] The feeding pipe 1 has an inlet pipe 11 connected to the inside of the feeding pipe on one side. The inlet pipe 11 is connected in sequence to the metering conveying device 7 and the scraper conveyor 6. The lower end of the feeding pipe 1 is connected to the glue mixer 8. The scraper conveyor 6 transports the wood shavings to the metering conveying device 7. After being metered by the metering conveying device 7, a fixed amount of wood shavings is transported through the inlet pipe 11 and the feeding pipe 1 to the glue mixer 8 for glue application. It should be noted that the above is a conventional setup in the particleboard glue application process, and the metering conveying device 7, scraper conveyor 6, and glue mixer 8 are all existing technologies.

[0025] In addition, a guide groove 12 is provided on the other side of the feeding pipe 1; the magnetic roller 2 is a cylindrical hollow roller body, and the two ends of the roller body are horizontally installed on the inner wall of the feeding pipe 1 through bearing seats and driven to rotate by a motor; multiple strip permanent magnets 21 are embedded on the surface of the roller body and are evenly distributed along the circumference of the roller body. All the strip permanent magnets 21 are flush with the surface of the roller body and the two ends are close to each other. Through these strip permanent magnets 21, magnetic metal impurities that are often mixed in with wood shavings can be adsorbed. The scraper 3 is L-shaped, and the corner of the scraper 3 is hinged to the connection point of the feed pipe 1 and the guide groove 12. One straight edge of the scraper 3 is connected to the feed pipe 1 through the spring 4, so that the other straight edge of the scraper 3 is in close contact with the top surface of the magnetic roller 2 under the action of the spring force of the spring 4. In use, the magnetic roller 2 adsorbs the metal impurities in the shavings on one side and drives the metal impurities to the other side by rotation, and then collects them by the scraper 3. During the peeling process, the elastic deformation of the spring 4 absorbs the positional deviation of the surface of the magnetic roller 2, avoiding rigid collision damage to the scraper 3 or the magnetic roller 2.

[0026] As a preferred embodiment, one end of the guide channel 12 is connected to the inside of the feeding pipe 1, and the other end of the guide channel 12 extends downward at an angle, with a collection box 9 provided below the end; in this way, after the metal impurities are peeled off by the scraper 3 from the magnetic roller 2, they can slide freely along the guide channel 12 into the collection box 9 for easy collection.

[0027] As a preferred embodiment, the scraper 3 is made of non-magnetic metal to prevent it from being attracted by the strip permanent magnet 21 and hindering the rotation of the magnetic roller 2. The upper edge of the straight edge of the scraper 3 that is close to the top surface of the magnetic roller 2 is chamfered, which is beneficial for the removal of metal impurities.

[0028] As a preferred embodiment, the feeding device of the particleboard core layer mixing machine 8 further includes a limiting tube 51, a nut 52, and a handle screw 53. The limiting tube 51 is square and welded to the outer wall of the feeding pipe 1. The nut 52 is disposed inside the limiting tube 51, and its shape and size are adapted to the inner hole of the limiting tube 51, so that it can be restricted from rotating by the limiting tube 51. A spring 4 is connected to one side of the nut 52. The rod end of the handle screw 53 is threaded into the nut 52, and the shank end of the handle screw 53 abuts against the limiting tube 51 under the tension of the spring 4. Since the nut 52 is restricted from rotating by the limiting tube 51, the nut 52 can move forward and backward along the rod end of the handle screw 53 within the limiting tube 51 by rotating the shank end of the handle screw 53, thereby adjusting the extension of the spring 4, and thus adjusting the initial pressure of the scraper 3 on the magnetic roller 2, so as to ensure the initial contact between the scraper 3 and the magnetic roller 2, while avoiding excessive initial pressure that would hinder the rotation of the magnetic roller 2.

[0029] The method of use or working principle of this utility model is as follows:

[0030] When the core layer wood shavings need to be uniformly glued using the glue mixer 8, the wood shavings are first transported to the metering conveyor 7 using the scraper conveyor 6. After being metered by the metering conveyor 7, a fixed amount of wood shavings are fed into the discharge pipe 1 through the feed pipe 11. The wood shavings are thrown out in a parabolic arc in the discharge channel and fall freely into the glue mixer 8 for glue application. During the process of throwing the wood shavings, the magnetic roller 2 above the wood shavings adsorbs the metal impurities in the wood shavings. The magnetic roller 2 is driven by a motor to rotate counterclockwise around its own axis, which brings these metal impurities to the top. Since the scraper 3 is in close contact with the top surface of the magnetic roller 2 under the action of the spring 4, these metal impurities can be peeled off the magnetic roller 2 by the scraper 3 under the action of relative motion. After being peeled off, they move along the scraper 3 and the guide groove 12 and finally fall into the collection box 9 for collection.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
