Description

Technical Field

[0001] This invention relates to the field of egg carton processing technology, and in particular to an egg carton forming mold with a handle. Background Technology

[0002] Most common plastic egg cartons on the market are made of PET (polyethylene terephthalate) or PP (polypropylene). Both of these are high-value recyclable items in waste plastic recycling. Their single material and simple structure meet the basic requirements of waste plastic recycling for "low impurities and easy separation".

[0003] Chinese Utility Model Patent Publication No. CN221717803U describes an egg packaging box forming process, including a control console and an upper mold. Uprights are installed at the four corners of the upper surface of the control console, and a top plate is mounted on the top of the four uprights. A lower mold is set on the upper surface of the control console, and pins are installed at the four corners of the bottom of the lower mold. Insertion holes for the pins are formed on the upper surface of the control console. A heating plate is slidably mounted on the upper side of the control console via a linear motion module, which is mounted on the lower surface of the top plate. A hydraulic cylinder is mounted on the upper surface of the top plate, with its extension end extending to the lower side of the top plate. A first mounting plate is installed at the end of the extension end of the hydraulic cylinder. The connecting mechanism allows for quick replacement of the upper mold, reducing production line downtime and improving production efficiency. Furthermore, when the hydraulic cylinder lowers the upper mold for pressing, a fixing mechanism can press and fix the plastic sheet, improving the yield rate.

[0004] There are still some problems with the egg carton during processing.

[0005] Plastic egg cartons are widely used in the food packaging industry due to their low cost and good protection. Their molding process relies on two core links: mold fixing and finished product unloading. In traditional molding equipment, mold fixing often uses simple clamps, resulting in uneven distribution of clamping force and easy mold displacement. In the finished product unloading stage, existing technologies often use a single robotic arm gripping or manual unloading mode, lacking the coordinated design of control components and flipping components. This not only results in low unloading efficiency but also easily causes damage and deformation of the egg carton's corners, making it difficult to meet the high precision and high efficiency requirements of large-scale production. Summary of the Invention

[0006] The purpose of this application is to provide an egg carton forming mold with a handle, which realizes the forming of the egg carton by the mold body, the downward movement of the mold body by the control component, and finally the unloading of the egg carton inside the mold body by the flipping component.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The present invention has a reasonable structure. The mold body is placed on the top surface of the support plate. Then, the threaded rod is rotated by rotating the handle. A horizontal plate is threadedly connected to the threaded rod. The horizontal plate is moved by rotating the threaded rod. The two ends of the horizontal plate are slidably connected to the slide rod. The rotation of the threaded rod causes the two ends of the horizontal plate to slide on the slide rod, which increases the stability of the horizontal plate movement. The movement of the horizontal plate causes the arm plate to clamp and fix the side of the mold body through the clamping plate, so as to avoid the mold body from shifting.

[0020] 2. In this invention, when the pallet is flipped over, the servo motor operates, which causes the drive rod to rotate. One end of the drive rod is fixedly connected to a second pulley. The rotation of the drive rod causes the second pulley to rotate, and the rotation of the second pulley drives the first pulley to rotate via a transmission belt. The first pulley is fixedly connected to the arm plate. The rotation of the first pulley causes the pallet to flip over. As the pallet moves up and down, the third pulley moves due to the elastic force of the spring, preventing the transmission belt from coming off.

[0021] 3. In this invention, when the mold body needs to be moved downward, the cylinder pulls the carrier plate through the docking seat. The bottom surface of the carrier plate is fixedly connected to the second slider, and the second slider is slidably connected to the second slide rail. The movement of the carrier plate causes the second slider to slide on the second slide rail, increasing the stability of the movement of the carrier plate. The movement of the carrier plate drives the pull plate to move, thereby facilitating the sliding of the roller inside the inclined groove, so that the movable plate moves downward as a whole, making it convenient to remove the formed egg carton inside the mold body.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Reference Figure 1 - Figure 7 The egg carton forming mold shown includes a mold body 1, which is mounted on the top surface of a tray 101. A shaft 102 is fixedly connected to the center of the bottom surface of the tray 101. One end of the shaft 102 is rotatably connected to a movable plate 103. A first slider 104 is fixedly connected to the center of the rear side of the movable plate 103. The first slider 104 is slidably connected to a first slide rail 105. The first slide rail 105 is fixedly mounted on a side plate 106. The bottom end of the side plate 106 is fixedly connected to a base plate 107. The mold also includes a fastening assembly, a rotating assembly, and a control assembly. The fastening assembly is located on both sides of the bottom surface of the tray 101 for mounting the mold body 1. The rotating assembly is located on the movable plate 103 for rotating the entire tray 101. The control assembly is located on the base plate 107 for use in conjunction with the mold body 1.

[0033] Specifically, it should be noted that the raw materials are added into the interior of the mold body 1, and an upper mold base is provided on the mold body 1. The mold body 1 and the upper mold base are used to facilitate the processing and shaping of the egg carton. The specific processing methods are all based on existing technologies and will not be elaborated on here.

[0034] As one embodiment of this invention, the fastening assembly includes a pair of through slots 2 formed on both sides of the support plate 101. An arm plate 201 is provided inside the pair of through slots 2. The top end of the arm plate 201 is fixedly connected to a clamping plate 202, which clamps one side of the mold body 1. The bottom end of the arm plate 201 is fixedly connected to a horizontal plate 203. A threaded rod 204 is threadedly connected to the middle of the horizontal plate 203. One end of the threaded rod 204 is fixedly connected to a throttle 205, and the other end of the threaded rod 204 is rotatably connected to a first bearing seat 206. The top end of the first bearing seat 206 is fixedly connected to the support plate 101. Both ends of the horizontal plate 203 are slidably connected to a slide rod 207. One end of the slide rod 207 is fixedly connected to a bracket 208, and the top end of the bracket 208 is fixedly connected to the bottom surface of the support plate 101.

[0035] Specifically, the mold body 1 is placed on the top surface of the support plate 101. Then, the threaded rod 204 is rotated by rotating the handle 205. A horizontal plate 203 is threaded onto the threaded rod 204. The horizontal plate 203 moves by rotating the threaded rod 204. The two ends of the horizontal plate 203 are slidably connected to the slide rod 207. The rotation of the threaded rod 204 causes the two ends of the horizontal plate 203 to slide on the slide rod 207, increasing the stability of the horizontal plate 203's movement. The movement of the horizontal plate 203 clamps and fixes the side of the mold body 1 through the clamping plate 202, preventing the mold body 1 from shifting.

[0036] In one embodiment of this invention, the rotating assembly includes a first pulley 3 fixedly mounted on a shaft 102. A transmission belt 301 is sleeved on the first pulley 3, and the transmission belt 301 is attached to a driven pulley 302. The driven pulley 302 is rotatably connected to a movable plate 103. One end of the transmission belt 301 is sleeved on a second pulley 303, which is fixedly connected to one end of a drive rod 304. The other end of the drive rod 304 is fixedly connected to the output end of a servo motor 305, which is fixedly mounted on a positioning plate 306. The positioning plate 306 is fixedly mounted on one side of a side plate 106. The other end of the transmission belt 301 is sleeved on a third pulley 307. Three pulleys 307 are rotatably connected to rod 308. The other end of rod 308 is fixedly connected to one side of sleeve block 309. Sleeve block 309 is slidably connected to side rod 310. One end of side rod 310 is fixedly connected to second bearing seat 311. Second bearing seat 311 is fixedly installed on the other side of side plate 106. The other end of side rod 310 is fixedly connected to collar 312. Spring 313 is sleeved on side rod 310. The two ends of spring 313 are fixedly connected to one side of sleeve block 309 and one side of collar 312, respectively. Sleeve seat 314 is fixedly connected to sleeve block 309. Sleeve seat 314 is slidably connected to limiting rod 315. One end of limiting rod 315 is fixedly connected to second bearing seat 311.

[0037] Specifically, when the pallet 101 is flipped over, the servo motor 305 operates, causing the drive rod 304 to rotate. One end of the drive rod 304 is fixedly connected to the second pulley 303. The rotation of the drive rod 304 causes the second pulley 303 to rotate, and the rotation of the second pulley 303 drives the first pulley 3 to rotate through the transmission belt 301. The first pulley 3 is fixedly connected to the arm plate 201. The rotation of the first pulley 3 causes the pallet 101 to flip over. As the pallet 101 moves up and down, the third pulley 307 moves due to the elastic force of the spring 313, preventing the transmission belt 301 from falling off.

[0038] In one embodiment of this invention, the control component includes a second slide rail 4 fixedly mounted on a base plate 107. A second slider 401 is slidably connected to the second slide rail 4. A carrying plate 402 is fixedly mounted on the top surface of the second slider 401. A pull plate 403 is fixedly connected to the top surface of the carrying plate 402. A groove 404 is provided on the pull plate 403. A roller 405 is slidably connected inside the groove 404. The roller 405 is rotatably connected to a frame plate 406. The top end of the frame plate 406 is fixedly connected to a movable plate 103. A docking seat 407 is fixedly connected to one side of the top surface of the carrying plate 402. A cylinder 408 is fixedly connected to the docking seat 407. The other end of the cylinder 408 is fixedly mounted on an L-shaped plate 409. The bottom end of the L-shaped plate 409 is fixedly connected to the base plate 107.

[0039] Specifically, when the mold body 1 needs to be moved downward, the cylinder 408 pulls the carrier plate 402 through the docking seat 407. The bottom surface of the carrier plate 402 is fixedly connected to the second slider 401, and the second slider 401 is slidably connected to the second slide rail 4. The movement of the carrier plate 402 causes the second slider 401 to slide on the second slide rail 4, increasing the stability of the movement of the carrier plate 402. The movement of the carrier plate 402 drives the pull plate 403 to move, thereby facilitating the sliding of the roller 405 inside the inclined groove 404, so that the movable plate 103 moves downward as a whole, making it convenient to remove the formed egg carton inside the mold body 1.

[0040] The working principle of this invention is as follows: The mold body 1 is placed on the top surface of the support plate 101. Then, the threaded rod 204 is rotated by rotating the handle 205. A horizontal plate 203 is threadedly connected to the threaded rod 204. The horizontal plate 203 moves by rotating the threaded rod 204. The two ends of the horizontal plate 203 are slidably connected to the slide rod 207. The rotation of the threaded rod 204 causes the two ends of the horizontal plate 203 to slide on the slide rod 207, which increases the stability of the movement of the horizontal plate 203. The movement of the horizontal plate 203 clamps and fixes the side of the mold body 1 through the clamping plate 202, so as to prevent the mold body 1 from shifting.

[0041] When the pallet 101 is flipped over, the servo motor 305 operates, which causes the drive rod 304 to rotate. One end of the drive rod 304 is fixedly connected to the second pulley 303. The rotation of the drive rod 304 causes the second pulley 303 to rotate. The rotation of the second pulley 303 drives the first pulley 3 to rotate through the transmission belt 301. The first pulley 3 is fixedly connected to the arm plate 201. The rotation of the first pulley 3 causes the pallet 101 to be flipped over. As the pallet 101 moves up and down, the third pulley 307 will move due to the elastic force of the spring 313 to prevent the transmission belt 301 from falling off.

[0042] When the mold body 1 needs to be moved downward, the cylinder 408 pulls the carrier plate 402 through the docking seat 407. The bottom surface of the carrier plate 402 is fixedly connected to the second slider 401, and the second slider 401 is slidably connected to the second slide rail 4. The movement of the carrier plate 402 causes the second slider 401 to slide on the second slide rail 4, increasing the stability of the movement of the carrier plate 402. The movement of the carrier plate 402 drives the pull plate 403 to move, which facilitates the roller 405 to slide inside the inclined groove 404, so that the movable plate 103 moves downward as a whole, making it convenient to remove the formed egg carton inside the mold body 1.

[0043] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
