[0002] The production process of cork boards mainly includes mixing, hot pressing, curing, demolding, and slitting. See Chinese Patent Publication No. CN221112213U, which discloses a cork hot pressing molding machine and specifically discloses the following technical solution: It includes an operating table with a detachable mold in the center of its top surface and first single-rod hydraulic cylinders on both sides. Heating grooves are opened on the upper parts of both sides of the mold's bottom plate. Mounting plates are provided on both sides of the bottom of the mold's bottom plate, with several fixing through holes on the mounting plates. Positioning grooves are opened on the top surface of the operating table corresponding to the mounting plates. A double-rod hydraulic cylinder is provided on the top surface of the operating table between the two positioning grooves. The two piston rods of the double-rod hydraulic cylinder are fixedly connected to fixing plates. Several fixing rods are provided on opposite sides of the two fixing plates. The lower part of the mounting plate is inserted into the corresponding positioning groove. The fixing rods correspond one-to-one with the fixing through holes on the same side and are inserted through them. Sealing plates are detachably connected to the piston rods of both first single-rod hydraulic cylinders. Lower electric heating plates are provided on both sealing plates and are inserted into the heating grooves.

[0003] Referring to Chinese Patent Publication No. CN1899782A, a method for producing cork boards and a dedicated cork board molding machine are disclosed, specifically outlining the following technical solution: The method includes mixing cork granules and adhesive evenly, weighing the mixture and evenly placing it within the mold frame of the molding machine, activating the upper and lower telescopic temperature-controlled hot press plates located at the upper and lower openings of the mold frame, pressing to the desired thickness of the cork board, molding and curing into a cork board, and removing the cork board. The molding machine includes a frame, on which a mold frame is mounted. Upper and lower temperature-controlled hot press plates are respectively located on the upper and lower open sides of the mold frame, and these plates are connected to upper and lower telescopic devices. The outer edges of the upper and lower temperature-controlled hot press plates align with the inner edges of the mold frame.

[0004] As can be seen from the above-mentioned prior art, in the production process of cork boards, it is usually necessary to lay material into a mold in order to achieve the production of boards by applying pressure to the mold. However, how to make the cork material in the mold evenly and quantitatively laid, and avoid material accumulation during the laying process, has become one of the technical problems that the industry needs to solve. Summary of the Invention

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] The automatic uniform material spreading mechanism for a hot press mold described in this application includes a material spreading box, which is rotatably mounted on one end of a telescopic frame. The telescopic frame has several frame wheels on both sides of its end away from the material spreading box, and the telescopic frame slides along a track via these frame wheels. A rotary positioning driver is also provided on the telescopic frame, and the rotary positioning driver engages with the circumferential gear teeth of the material spreading box via a drive gear. A material feeding disc is also provided inside the material spreading box, and a material feeding transmission wheel is provided at the top of the material feeding disc.

[0017] The technical solutions described in this application will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1

[0019] See Figures 1 to 2 An automatic uniform material spreading mechanism for a hot press mold includes a telescopic frame 1. A material spreading box 7 is rotatably mounted at one end of the telescopic frame 1, extending downwards from the telescopic frame 1. A conveyor belt 2 extending towards the top entrance of the material spreading box 7 is also mounted on the telescopic frame 1, with the other end of the conveyor belt 2 receiving the material. The material spreading box 7 is a hollow box, and a material feeding disc 5 is disposed inside the material spreading box 7. The material feeding disc 5 includes a material feeding shaft 9 coaxially mounted with the material spreading box 7. A material feeding drive wheel 8 is mounted at the top of the material feeding shaft 9. Material feeding blades 10 are disposed on the material feeding shaft 9 at positions inside the material spreading box 7, and the material feeding blades 10 are evenly distributed around the material feeding shaft 9. The top edge of the material distribution box 7 is provided with several gear teeth. The material distribution box 7 is driven by the gear teeth meshing with the drive gear on the rotary positioning driver 4. The rotary positioning driver 4 includes a drive motor and a gearbox, and the drive gear is located at the output end of the gearbox. The rotary positioning driver 4 is located on the telescopic frame 1. The telescopic frame 1 is also provided with a material feeding driver 11 at the end near the material distribution box 7. The material feeding driver 11 includes a drive motor and a gearbox. The output end of the gearbox of the material feeding driver 11 is connected to the material feeding transmission wheel 8 through a transmission mechanism. The telescopic frame 1 is provided with frame traveling wheels 3 on both sides at the end away from the material distribution box 7. There are multiple sets of frame traveling wheels 3. The telescopic frame 1 slides along the traveling track of the frame through the frame traveling wheels 3.

[0020] Example 2

[0021] See also Figures 1 to 2 An automatic uniform material spreading mechanism for a hot press mold is disclosed. The spreading box 7 has a rotating positioning dial 6, composed of a right-angled plate or block, located at its top edge. The rotating positioning dial 6 rotates with the spreading box 7. The structure and connections of the remaining parts are the same as those described in the preceding embodiments.

[0022] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0023] In the above embodiment, the telescopic frame 1 is a frame structure that supports the rotary positioning driver 4, the material feeding disc 5, the material spreading box 7, and the material feeding driver 11. A conveyor belt 2 is provided above the middle position of the telescopic frame 1. The inlet end of the conveyor belt 2 is used to receive the material, and the outlet of the conveyor belt 2 is located above the inlet of the material spreading box 7.

[0024] In the above embodiment, the telescopic frame 1 is provided with frame traveling wheels 3 on both sides of the end away from the material distribution box 7. The frame traveling wheels 3 are symmetrically distributed on both sides, and the telescopic frame 1 moves horizontally along the traveling track on the frame via the frame traveling wheels 3. In the prior art, the sliding of the telescopic frame 1 along the traveling track on the frame via the frame traveling wheels 3 can be achieved by a horizontal telescopic mechanism, such as a horizontally set hydraulic cylinder. The lifting mechanism, such as a chain lifting mechanism or a lifting hydraulic cylinder, can be used to raise and lower the frame with the traveling track relative to the horizontal plane, thereby achieving the raising and lowering of the telescopic frame 1 relative to the horizontal plane.

[0025] In the above embodiment, the rotary positioning driver 4 is disposed on the side of the telescopic frame 1 near the material box 7, and includes a drive motor and a gearbox body connected to the output shaft of the drive motor. The output end of the gearbox body is provided with a drive gear.

[0026] In the above embodiment, the material feeding disc 5 is located inside the material spreading box 7 and includes a material feeding shaft 9 and material feeding blades 10. The material feeding shaft 9 is coaxially arranged with the material spreading box 7 and connected to the material spreading box 7 through a frame with bearings. A material feeding drive wheel 8 is provided at the top end of the material feeding shaft 9. The material feeding blades 10 are located in the material spreading box 7 and fixedly connected to the material feeding shaft 9. The material feeding blades 10 are evenly distributed around the central axis of the material feeding shaft 9. The material feeding drive wheel 8 is used to transmit external power to the material feeding shaft 9, thereby realizing the relative rotation between the material feeding shaft 9 and the material spreading box 7.

[0027] In the above embodiment, the material distribution box 7 is a hollow cylinder with an opening at the top. A gear tooth structure is provided at the edge of the top opening of the material distribution box 7, and the material distribution box 7 is driven by the gear tooth structure at the edge of the top opening meshing with the drive gear in the rotary positioning driver 4.

[0028] In the above embodiment, a rotating positioning dial 6 is also fixedly installed at the top opening of the material distribution box 7. The rotating positioning dial 6 is a right-angled plate or block, which can limit the material distribution box 7 at the corner position through the right-angled side during the rotation of the material distribution box 7. After the material distribution box 7 is positioned by the rotating positioning dial 6, the material distribution box 7 stops rotating.

[0029] In the above embodiment, the telescopic frame 1 is further provided with a material feeding driver 11 at the end near the material distribution box 7. The material feeding driver 11 is connected to the material feeding transmission wheel 8 through a transmission mechanism. The material feeding driver 11 includes a drive motor and a gearbox housing connected to the output shaft of the drive motor. When both the output end of the material feeding driver 11 and the material feeding transmission wheel 8 are synchronous pulley structures, the connection can be achieved through a transmission belt. Those skilled in the art can also achieve power transmission through suitable transmission structures in the prior art.

[0030] In use, the material distribution box 7 moves horizontally towards the mold along with the telescopic frame 1 under the action of the frame's traveling wheels 3 and the horizontal drive mechanism to facilitate the material's entry into the mold. During this movement, the material distribution box 7 rotates under the action of the rotary positioning driver 4, which in turn rotates the rotary positioning dial 6, thus positioning one of the four corners of the mold. Once the right-angled edge of the rotary positioning dial 6 is in contact with the mold, the rotary positioning driver 4 and the material distribution box 7 stop rotating. At this point, sufficient material distribution distance remains between the bottom of the material distribution box 7 and the bottom surface of the mold. After this process is completed, the material can be conveyed to the material distribution box 7 via the conveyor belt 2, and the material can be quantitatively and accurately deposited into the material distribution box 7 with the assistance of the dispensing mechanism.

[0031] At this time, the material feeding disc 5 in the feeding box 7 begins to rotate under the action of the material feeding transmission wheel 8 and the material feeding driver 11, evenly distributing the material falling into the feeding box 7 into the hot press mold, ensuring that the material is evenly distributed in the mold and does not accumulate. During the material distribution process at the corner of the mold, the rotation of the feeding box 7 again drives the rotation of the rotary positioning disc 6, and the right-angled edge of the rotary positioning disc 6 is used to make it fit against the inner wall of the mold, thereby achieving material distribution at the corner position of the feeding box 7. After the material distribution is completed, the telescopic frame 1, the feeding box 7, the rotary positioning disc 6, etc., return to their initial state.

[0032] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. 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.
