Description

Technical Field

[0001] This utility model relates to a paper tray production equipment, and more particularly to a single-mold reciprocating automatic machine. Background Technology

[0002] Paper trays are widely used in the packaging of various products to support and protect them, facilitating packaging and providing protection. During paper tray production, the pulp needs to be initially formed by removing water using negative pressure, followed by initial extrusion through a mold, then hot-pressing and drying before final removal. After initial forming, the pulp needs to be moved to a hot press for drying. Therefore, the upper mold is placed on a slide rail to facilitate the movement of the initially formed paper tray to the hot press for drying. However, during forming and hot-pressing, the force between the upper and lower molds is significant. This force is transmitted from the upper mold to the slide rail, causing it to deform easily and affecting its lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a single-mode reciprocating automatic machine that can solve at least one of the above-mentioned problems.

[0004] According to one aspect of this utility model, a single-mold reciprocating automatic machine is provided, including a frame, a forming station, a hot pressing station, and a horizontal moving platform. The forming station and the hot pressing station are arranged sequentially on the frame. The horizontal moving platform corresponds to the forming station and the hot pressing station. The horizontal moving platform includes a moving frame, a hot pressing upper mold, and a transfer mold. The transfer mold is fixed below the moving frame. A guide sleeve is provided below the moving frame. A guide rod and a mounting plate are provided on the hot pressing upper mold. One end of the guide rod is connected to the hot pressing upper mold, and the other end passes through the guide sleeve and is connected to the mounting plate. The mounting plate is correspondingly arranged with the frame. A slide rail is provided on the frame, and the moving frame cooperates with the slide rail.

[0005] The beneficial effects of this utility model are as follows: By providing a guide sleeve below the moving frame, when the hot pressing upper mold is subjected to pressure at the forming station and the hot pressing station, the hot pressing upper mold and the guide rod can move upward relative to the guide sleeve, thereby causing the moving frame to move upward a certain distance. This allows the top of the moving frame to transmit the force to the machine frame instead of acting downward on the slide rail, thus avoiding stress on the slide rail, effectively preventing the slide rail from being deformed under pressure, and ensuring the service life of the slide rail. At the same time, by fixing both the hot pressing upper mold and the transfer mold on the moving frame, the synchronization of the two is ensured.

[0006] In some embodiments, the molding station includes a suction mold and a suction mold lifting device. The suction mold lifting device includes a lifting cylinder, a connecting beam, and a lifting rod. The cylinder body of the lifting cylinder is mounted on the frame, and its piston rod extends upward. The connecting beam is connected to the piston rod of the lifting cylinder. The top end of the lifting rod is connected to the connecting beam, and the bottom end is connected to the suction mold, which is located below the upper hot-pressing mold. Thus, the lifting cylinder can drive the lifting rod to move up and down, thereby driving the suction mold to move up and down to meet the corresponding usage requirements.

[0007] In some embodiments, the hot pressing station includes a lower hot pressing mold and a hot pressing mold lifting device. A mounting rod is provided on the frame, and the mounting rod is vertically arranged. The hot pressing mold lifting device includes a hot pressing base plate, a hydraulic cylinder, and a hot pressing middle plate. The hot pressing base plate is fixed to the mounting rod, the cylinder body of the hydraulic cylinder is fixed to the hot pressing base plate, the lower hot pressing mold is fixed to the hot pressing middle plate, the hot pressing middle plate is sleeved on the mounting rod, and the hot pressing middle plate is connected to the piston rod of the hydraulic cylinder. The lower hot pressing mold is located below the upper hot pressing mold. Thus, through the various structures of the hot pressing mold lifting device, the lower hot pressing mold can move up and down, thereby facilitating the engagement and separation of the lower hot pressing mold and the transfer mold.

[0008] In some embodiments, the lower hot press mold is located on one side of the suction mold, and the transfer mold corresponds to the lower hot press mold. This facilitates the coordination between the upper hot press mold, the suction mold, and the lower hot press mold.

[0009] In some embodiments, the single-mold reciprocating automatic machine also includes a hot-pressing top plate, with a mounting plate located below the hot-pressing top plate and capable of abutting against it. Thus, by providing a hot-pressing top plate, when the lower hot-pressing mold closes upward with the upper hot-pressing mold, the mounting plate acts upward on the hot-pressing top plate, thereby ensuring that the hot-pressing top plate is stressed while the slide rail is not.

[0010] In some embodiments, the hot-pressing upper mold includes an upper mold top plate, and the transfer mold includes a transfer mold top plate. The hot-pressing upper mold is connected to the movable frame via the upper mold top plate, and the transfer mold is connected to the movable frame via the transfer mold top plate. A guide sleeve is fixed below the upper mold top plate. This facilitates the installation of the hot-pressing upper mold and the transfer mold on the movable frame.

[0011] In some embodiments, sliders are fixed to the bottom of the upper mold top plate and the transfer mold top plate. The sliders cooperate with slide rails, which are mounted on the frame and extend from the forming station to the hot pressing station, exceeding the hot pressing station. Thus, the cooperation between the sliders and the slide rails improves the stability of the entire moving frame.

[0012] In some embodiments, the single-mold reciprocating automatic machine also includes a synchronous lifter, which is mounted on the frame, and the lifting rods are connected to the connecting beam via the synchronous lifter. Thus, by including the synchronous lifter, the synchronous lifting of each lifting rod can be achieved, thereby facilitating the smooth lifting of the suction mold. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Reference Figures 1-7 A single-mold reciprocating automatic machine includes a frame 1, a forming station 2, a hot pressing station 3, and a horizontal moving platform 4. The forming station 2 and the hot pressing station 3 are arranged sequentially on the frame 1. The horizontal moving platform 4 corresponds to the forming station 2 and the hot pressing station 3. The horizontal moving platform 4 includes a moving frame 41, a hot pressing upper mold 42, and a transfer mold 43. The transfer mold 43 is fixed below the moving frame 41. A guide sleeve 44 is provided below the moving frame 41. A guide rod 45 and a mounting plate 46 are provided on the hot pressing upper mold 42. One end of the guide rod 45 is connected to the hot pressing upper mold 42, and the other end passes through the guide sleeve 44 and is connected to the mounting plate 46. The mounting plate 46 is correspondingly set to the frame 1. A slide rail 5 is provided on the frame 1, and the moving frame 41 cooperates with the slide rail 5.

[0022] When the single-mold reciprocating automatic machine of this utility model is in use, the hot pressing upper mold 42 performs preliminary forming on the paper tray at the forming station 2. Then, the horizontal moving platform 4 moves to one side of the hot pressing station 3 under the action of external force, so that the hot pressing upper mold 42 moves to the hot pressing station 3 for hot pressing, and achieves drying and forming. After the paper tray on the transfer mold 43 is hot pressed, it moves outward to facilitate the unloading of the paper tray on the transfer mold 43.

[0023] The molding station 2 includes a suction mold 21 and a suction mold lifting device 22. The suction mold lifting device 22 includes a lifting cylinder 221, a connecting beam 222, and a lifting rod 223. The cylinder body of the lifting cylinder 221 is mounted on the frame 1, and its piston rod extends upward. The connecting beam 222 is connected to the piston rod of the lifting cylinder 221. The top end of the lifting rod 223 is connected to the connecting beam 222, and the bottom end is connected to the suction mold 21. The suction mold 21 is located below the hot press upper mold 42. Thus, the lifting cylinder 221 is inverted on the frame 1, reducing the height of the entire lifting cylinder 221 beyond the frame 1. When the piston rod of the lifting cylinder 221 extends upward, it drives the lifting rod 223 to move upward through the connecting beam 222, thereby driving the suction mold 21 to move upward. Conversely, when the piston rod of the lifting cylinder 221 is pulled back, it drives the suction mold 21 to move downward.

[0024] The specific working process of molding station 2 is as follows:

[0025] The horizontal moving platform 4 moves towards the suction mold 21, so that the hot pressing upper mold 42 is directly above the suction mold 21. At this time, the suction mold 21, after suctioning the slurry, moves upward to below the hot pressing upper mold 42 under the action of the suction mold lifting device 22, realizing the closing of the hot pressing upper mold 42 and the suction mold 21, and initially forming the paper tray. After the paper tray is initially formed, the suction mold lifting device 22 drives the suction mold 21 downward, realizing the separation of the suction mold 21 and the hot pressing upper mold 42, and the paper tray stays on the hot pressing upper mold 42.

[0026] Subsequently, an external force is applied to the horizontal moving platform 4, pushing the horizontal moving platform 4 to move towards the hot pressing station 3, so that the hot pressing upper mold 42 moves to the hot pressing station 3.

[0027] The hot pressing station 3 includes a lower hot pressing mold 31 and a hot pressing mold lifting device 32. A mounting rod 11 is provided on the frame 1, and the mounting rod 11 is vertically arranged. The hot pressing mold lifting device 32 includes a hot pressing base plate 321, a hydraulic cylinder 322, and a hot pressing middle plate 323. The hot pressing base plate 321 is fixed to the mounting rod 11, the cylinder body of the hydraulic cylinder 322 is fixed to the hot pressing base plate 321, the lower hot pressing mold 31 is fixed to the hot pressing middle plate 323, and the hot pressing middle plate 323 is sleeved on the mounting rod 11. The hot pressing middle plate 323 is connected to the piston rod of the hydraulic cylinder 322. The lower hot pressing mold 31 is located below the upper hot pressing mold 42. The extension and retraction of the piston rod of the hydraulic cylinder 322 can drive the hydraulic middle plate 323 to rise and fall, thereby driving the synchronous rise and fall of the lower hot pressing mold 31.

[0028] Among them, the hot pressing lower mold 31 is located on one side of the suction mold 21, and the transfer mold 43 corresponds to the hot pressing lower mold 31.

[0029] When the upper hot-pressing mold 42 is pushed to the hot-pressing station 3, the piston rod of the hydraulic cylinder 322 extends, pushing the lower hot-pressing mold 31 upward until it closes with the upper hot-pressing mold 42, thus hot-pressing the paper tray. After the paper tray is hot-pressed and formed, the hydraulic cylinder 322 drives the lower hot-pressing mold 31 downward, at which point the paper tray is transferred onto the lower hot-pressing mold 31.

[0030] After the paper tray is hot-pressed, external force pushes the horizontal moving platform 4 back to directly above the suction mold 21. While the upper hot-press mold 42 and the lower hot-press mold 31 are hot-pressing the paper tray, the suction mold 21 draws pulp downwards from the pulp tank and then moves upwards to dewater. This allows the upper hot-press mold 42 to move directly above the suction mold 21, enabling the suction mold 21 to close upwards and form the paper tray, thus making efficient use of time and improving efficiency.

[0031] When the upper hot-pressing mold 42 and the suction mold 21 are closed to form the paper tray, the lower hot-pressing mold 31 is pushed upward by the hydraulic cylinder 322, causing it to close with the transfer mold 43. This allows the paper tray, previously placed on the lower hot-pressing mold 31, to be transferred to the transfer mold 43. When the upper hot-pressing mold 42 moves towards the lower hot-pressing mold 31, the transfer mold 43, connected to the moving frame 41, moves outward synchronously, facilitating the removal of the formed paper tray from the transfer mold 43 and simplifying the operation.

[0032] The single-mold reciprocating automatic machine of this utility model also includes a hot press top plate 6, and a mounting plate 46 is located below the hot press top plate 6, and the mounting plate 46 can abut against the hot press top plate 6.

[0033] In actual use, due to the cooperation between the guide rod 45 and the guide sleeve 44, when the upper hot-pressing mold 42 is pushed upward by the lower hot-pressing mold 31, the guide rod 45 moves upward relative to the guide sleeve 44. This causes the guide rod 45 to drive the mounting plate 46 to move upward synchronously, ensuring that neither the mounting plate 46 nor the upper hot-pressing mold 42, which is pushed upward by the guide rod 45, is pressed tightly against the slide rail 5. At this time, the mounting plate 46 abuts against the hot-pressing top plate 6, allowing the force to be transmitted to the hot-pressing top plate 6. This prevents excessive load on the slide rail 5, avoids deformation due to excessive force, and ensures the service life of the slide rail 5.

[0034] Similarly, when the suction mold 21 acts upward on the hot press upper mold 42, the guide rod 45 moves upward relative to the guide sleeve 44, causing the mounting plate 46 to move upward and act on the frame 1, so that the force is transmitted to the frame 1, avoiding excessive force and deformation of the slide rail 5.

[0035] The hot pressing upper mold 42 includes an upper mold top plate 421, and the transfer mold 43 includes a transfer mold top plate 431. The hot pressing upper mold 42 is connected to the moving frame 41 through the upper mold top plate 421, and the transfer mold 43 is connected to the moving frame 41 through the transfer mold top plate 431. The guide sleeve 44 is fixed below the upper mold top plate 421.

[0036] A slider 7 is fixed to the bottom of the upper mold top plate 421 and the transfer mold top plate 431. The slider 7 cooperates with the slide rail 5, which is located on the frame 1. The slide rail 5 extends from the forming station to the hot pressing station 3 and extends beyond the hot pressing station 3. In actual use, both ends of the moving frame 41 are fixed to the upper mold top plate 421 and the transfer mold top plate 431 by bolts, so that the hot pressing upper mold 42 and the transfer mold 43 can move synchronously on the moving frame 41.

[0037] The single-mold reciprocating automatic machine of this utility model also includes a synchronous lifter 8, which is mounted on the frame 1. The lifting rod 223 is connected to the connecting beam 222 after passing through the synchronous lifter 8. The synchronous lifter 8 is existing technology, and its specific working principle will not be described in detail. In actual use, because the suction mold 21 has a large weight when suctioning, two lifting cylinders 221 are installed on the frame 1, respectively connected to both sides of the suction mold 21. To ensure the synchronous lifting of the connecting beam 222 and the lifting rod 223 on both sides, the synchronous lifter 8 is installed on the frame 1. This facilitates the synchronous lifting of the lifting rods passing through the synchronous lifter 8, thereby improving the stability of the suction mold 21's lifting and ensuring the quality of the final formed paper tray.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
