Description

Technical Field

[0001] This utility model relates to the field of corn stalk board production technology, specifically to a corn stalk board pressing machine. Background Technology

[0002] Corn stalks are a dual-purpose crop, used primarily as feed, and also as a vital resource for industrial and agricultural production. Rich in nutrients and usable chemical components, corn stalks can be used as a raw material for livestock feed. With technological advancements, the uses of corn stalks have become increasingly widespread. Corn stalk boards are environmentally friendly boards made using MDI or isocyanate adhesives through a high-temperature, high-pressure process. No formaldehyde is released during production, meeting environmental standards.

[0003] Corn stalk boards are made from agricultural waste such as corn stalks and wheat stalks, and are produced through processes such as crushing, drying, mixing with adhesives, and hot pressing.

[0004] Traditional corn stalk board production requires removing the formed boards from the pressing equipment before pressing the next board. This process takes a lot of time for both feeding and unloading, resulting in poor process continuity. Furthermore, once the boards are pressed into the forming mold, they are difficult to remove, further reducing the production efficiency of corn stalk board processing. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a corn stalk board pressing machine, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a corn stalk board pressing machine, comprising: A workbench, the top of which is provided with two symmetrically distributed feeding hoppers; The hot pressing device includes a bracket fixedly connected to the top of the workbench, on which two symmetrically distributed cylinders are mounted, and the telescopic ends of the two cylinders are fixedly connected to the same hot pressing plate. The plate-making mechanism includes a drive motor mounted on the outside of the worktable. The output shaft of the drive motor is fixedly connected to a threaded rod. Two internal threaded blocks are threadedly connected to the outside of the threaded rod. A forming box is fixedly connected to the outside of each of the two internal threaded blocks. The unloading mechanism includes a servo motor located below the workbench. The output shaft of the servo motor is fixedly connected to a transmission shaft. A rotating bar is fixedly connected to the outside of the transmission shaft. Two symmetrically distributed fixed rods are fixedly connected to the outside of the rotating bar. The inner walls of both molding boxes are provided with top plates. Four rectangularly distributed vertical rods are fixedly connected to the bottom of the top plates.

[0007] Preferably, the top center of the workbench has a through mounting groove, and the threaded rod is movably connected to the inner wall of the mounting groove via a bearing.

[0008] Preferably, the inner wall of the mounting groove has two symmetrically distributed sliding grooves, and the outer side of the internal thread block is fixedly connected to two symmetrically distributed sliders, and the two sliders are slidably connected to the inner wall of the corresponding sliding groove.

[0009] Preferably, a motor mount is fixedly connected to the bottom of the worktable, and the servo motor is mounted on the outside of the motor mount.

[0010] Preferably, the bottom of the molding box has four through holes, and the bottom end of the vertical rod passes through the through holes and is slidably connected to the inner wall of the through holes.

[0011] Preferably, the bottom ends of two adjacent vertical rods are fixedly connected to the same connecting block, and the top of the connecting block is fixedly connected to a spring, which is fixedly connected to the bottom of the molding box.

[0012] Preferably, the top of the workbench has two symmetrically distributed through slots, and the bottom end of the vertical rod passes through the through slots and extends out of the workbench.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments. Example 1:

[0020] Reference Figure 1-4 The first embodiment of this utility model discloses a corn stalk board pressing machine, comprising: Workbench 1, with two symmetrically distributed feeding hoppers 5 on the top of workbench 1; The hot pressing device 2 includes a bracket 201 fixedly connected to the top of the workbench 1 for supporting and fixing the cylinder 202. Two symmetrically distributed cylinders 202 are installed on the bracket 201 for pushing the hot pressing plate 203 to move up and down. The telescopic ends of the two cylinders 202 are fixedly connected to the same hot pressing plate 203 for pressing the corn stalk board in conjunction with the forming box 305. The plate-making mechanism 3 includes a drive motor 307 installed on the outside of the workbench 1. The output shaft of the drive motor 307 is fixedly connected to a threaded rod 303. Two internal threaded blocks 304 are threadedly connected to the outside of the threaded rod 303. A forming box 305 is fixedly connected to the outside of each of the two internal threaded blocks 304.

[0021] The drive motor 307 drives the threaded rod 303 to rotate through the output shaft. The rotation of the threaded rod 303 drives the two internal threaded blocks 304 to move, thereby driving the upper molding box 305 to move, and alternately moving the two molding boxes 305 to the bottom of the hot press plate 203.

[0022] Specifically, a through mounting groove 302 is provided in the middle of the top of the workbench 1, and the threaded rod 303 is movably connected to the inner wall of the mounting groove 302 through a bearing.

[0023] The mounting slot 302 is used for mounting the threaded rod 303, and the internal threaded block 304 can move easily inside the mounting slot 302.

[0024] Specifically, the inner wall of the mounting groove 302 has two symmetrically distributed sliding grooves 301, and the outer side of the internal thread block 304 is fixedly connected to two symmetrically distributed sliders 306, and the two sliders 306 are slidably connected to the inner wall of the corresponding sliding groove 301.

[0025] The sliding groove 301 limits the movement trajectory of the slider 306. With the cooperation of the sliding groove 301 and the slider 306, the movement trajectory of the internal thread block 304 is limited, ensuring that when the threaded rod 303 rotates, the two internal thread blocks 304 drive the two forming boxes 305 to move in a straight line. Example 2:

[0026] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The discharge mechanism 4 includes a servo motor 410 located below the workbench 1. The output shaft of the servo motor 410 is fixedly connected to a transmission shaft 411. A rotating bar 402 is fixedly connected to the outside of the transmission shaft 411. Two symmetrically distributed fixed rods 408 are fixedly connected to the outside of the rotating bar 402. The inner walls of the two forming boxes 305 are each provided with a top plate 406. Four rectangularly distributed vertical rods 403 are fixedly connected to the bottom of the top plate 406.

[0027] The servo motor 410 drives the rotating bar 402 to rotate via the transmission shaft 411. The rotation of the rotating bar 402 pushes the connecting block 404 upward through the fixed rod 408. This, in conjunction with the vertical rod 403, pushes the top plate 406 inside the molding box 305 upward, thus ejecting the molded corn stalk board from the molding box 305 and completing the discharge of the molded corn stalk board.

[0028] Specifically, a motor mount 409 is fixedly connected to the bottom of the workbench 1, and a servo motor 410 is installed on the outside of the motor mount 409.

[0029] The motor mount 409 facilitates the installation of the servo motor 410 and ensures the stability of the servo motor 410 during operation.

[0030] Specifically, the bottom of the molding box 305 has four through holes 407, the bottom end of the vertical rod 403 passes through the through holes 407 and is slidably connected to the inner wall of the through holes 407.

[0031] The through hole 407 facilitates the sliding of the vertical rod 403 and limits the movement trajectory of the vertical rod 403, ensuring that the vertical rod 403 can only move in the up and down direction, which facilitates pushing the top plate 406 to eject the formed plate.

[0032] Specifically, the bottom ends of two adjacent vertical rods 403 are fixedly connected to the same connecting block 404, and the top of the connecting block 404 is fixedly connected to a spring 405, which is fixedly connected to the bottom of the molding box 305.

[0033] Under the action of the connecting block 404, two adjacent vertical rods 403 can be connected. The connecting block 404 can push the vertical rods 403 to move upward, so that the top plate 406 inside the forming box 305 moves upward, and the forming plate is discharged.

[0034] Spring 405 can reset top plate 406, thus facilitating the discharge of the next formed sheet.

[0035] Specifically, two symmetrically distributed through slots 401 are provided on the top of the workbench 1, and the bottom end of the vertical rod 403 passes through the through slots 401 and extends to the outside of the workbench 1.

[0036] The through groove 401 facilitates the movement of the forming box 305 without affecting the upward or downward movement of the vertical rod 403, thus facilitating the discharge of the formed sheet material.

[0037] The remaining structure is the same as that in Example 1.

[0038] The workflow of this utility model is as follows: Material for making corn stalk boards is injected into the forming box 305 below through the feeding hopper 5. The drive motor 307 drives the threaded rod 303 to rotate through the output shaft. The rotation of the threaded rod 303 drives the two forming boxes 305 to move through the internal threaded block 304 until the forming box 305 loaded with material moves to the bottom of the hot press plate 203. At this time, the other forming box 305 moves to the bottom of the other feeding hopper 5. The cylinder 202 pushes the hot press plate 203 downward to press the material in the forming box 305. At the same time, the feeding hopper 5 injects material into the forming box 305 below. After the material in the forming box 305 is pressed, the drive motor 307 rotates in the opposite direction to move the forming box 305 with the subsequently injected material to below the hot press plate 203. The formed box 305 after pressing moves to the discharge area. The servo motor 410 drives the rotating bar 402 to rotate via the transmission shaft 411. The rotation of the rotating bar 402 pushes the connecting blocks 404 on both sides to move upward via the fixed rod 408. The upward movement of the connecting blocks 404 pushes the top plate 406 to move upward via the vertical rod 403, thus pushing out the formed plate in the forming box 305 and completing the unloading of the plate. After the material is discharged, the production material is injected into the forming box 305 again through the feeding hopper 5 to press the next batch of corn stalk boards, and so on.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
