[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material, shaping paper products into various shapes through molds on a molding machine. This technology uses a wide range of raw materials, including waste cardboard and waste white paper, and the production process is harmless to the environment because the raw materials are recyclable.

[0003] Most existing pulp molding and pressing devices use a manual method of replacing pulp molds. After working for a long time, workers will become tired and thus reduce work efficiency. The operation is complicated and there are certain safety hazards. They are also unable to meet the needs of large-scale production and are prone to delaying delivery progress.

[0004] For this, a solution is needed. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides a pulp molding and pressing device to solve the problems raised in the above background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A pulp molding and pressing device comprises a workbench, a conveyor belt, a plurality of bases, a plurality of support columns, a work box, a hydraulic cylinder, a pressing die, a fixing mechanism, and a control mechanism, wherein the conveyor belt is arranged inside the workbench, the plurality of bases are evenly arranged at the bottom of the workbench, the plurality of support columns are evenly arranged at the top of the workbench, the work box is arranged at the top of the plurality of support columns, the hydraulic cylinder is arranged at the top of the work box, the pressing die is arranged at the bottom of the work box, the fixing mechanism is arranged at the top of the workbench and at the bottom of the work box, and the control mechanism is arranged at the rear ends of the plurality of support columns;

[0008] The fixing mechanism includes a plurality of hydraulic rods, a plurality of fixed blocks, a plurality of fixed plates, a plurality of transverse grooves, a plurality of grooves and a pressure-bearing mold. The hydraulic rods are oppositely arranged at the left and right ends of the top of the workbench and are both located at the bottom of the work box. The fixed block is arranged on the top of each of the hydraulic rods. The fixed plate is a rectangular structure and is arranged horizontally on the opposite sides of the two fixed blocks. The transverse groove is arranged inside each of the fixed plates and the openings are distributed opposite to each other. The plurality of grooves are evenly arranged at the bottom of each transverse groove and the openings are upward. The pressure-bearing mold is arranged between the two fixed plates.

[0009] Preferably, the fixing block and the fixing plate are integrally formed, and the groove is a rectangular parallelepiped structure.

[0010] Preferably, the pressure-bearing mold includes a mold plate, a plurality of pressure grooves, an anti-slip pad, a plurality of fixed arms and a plurality of raised blocks, the plurality of pressure grooves are evenly arranged on the top of the mold plate, the anti-slip pad is arranged on the bottom of the mold plate, the plurality of fixed arms are oppositely arranged at the left and right ends of the mold plate, and the plurality of raised blocks are evenly arranged on the top of each fixed arm.

[0011] Preferably, the fixed arm is a rectangular parallelepiped structure, the protruding block has the same structure as the groove, and the mold plate, the plurality of pressing grooves, the plurality of fixed arms and the plurality of protruding blocks are integrally formed.

[0012] Preferably, the thickness of the fixing arm plus the protruding block is less than the height of the transverse groove.

[0013] The utility model provides a pulp molding and pressing device, which has the following beneficial effects:

[0014] 1. This solution designs a fixing mechanism and a control mechanism. The pressure-bearing mold can be transferred to the fixing mechanism on the workbench through the conveyor belt. Fixed arms are provided on both sides of the pressure-bearing mold, which can be embedded in the transverse groove as the conveyor belt moves. Moreover, when the pressure-bearing mold is on the conveyor belt, its height is slightly lower than the top of the transverse groove, and its bottom, including the bottom of the protruding block, is also higher than the bottom of the transverse groove. Therefore, it can ensure that the pressure-bearing mold can move unimpeded. The control mechanism can enable the hydraulic rod to drive the fixed plate and the pressure-bearing mold to rise and leave the conveyor belt, thereby avoiding the subsequent pressing work from affecting the conveyor belt and the workbench.

[0015] 2. Meanwhile, workers only need to ensure the pressure-bearing molds are aligned at the back end of the workbench. Each mold passes through a laser scanner, and the control computer records the distance between them. This ensures that each protrusion in the mold precisely aligns with each groove, ensuring that subsequent pressing is foolproof. This solution significantly improves the device's efficiency and achieves automation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The embodiment of the utility model provides a technical solution to achieve this: a workbench 1, a conveyor belt 2, several bases 3, several support columns 4, a work box 5, a hydraulic cylinder 6, a pressing mold 7, a fixing mechanism 8 and a control mechanism 9. The conveyor belt 2 is arranged inside the workbench 1, the several bases 3 are evenly arranged at the bottom of the workbench 1, the several support columns 4 are evenly arranged on the top of the workbench 1, the work box 5 is arranged on the top of the several support columns 4, the hydraulic cylinder 6 is arranged on the top of the work box 5, the pressing mold 7 is arranged at the bottom of the work box 5, the fixing mechanism 8 is arranged on the top of the workbench 1 and at the bottom of the work box 5, and the control mechanism 9 is arranged at the rear end of the several support columns 4.

[0023] The core, the fixing mechanism 8 includes a plurality of hydraulic rods 81, a plurality of fixed blocks 82, a plurality of fixed plates 83, a plurality of transverse grooves 84, a plurality of grooves 85 and a pressure-bearing mold 86. The hydraulic rods 81 are arranged oppositely at the left and right ends of the top of the workbench 1 and are both located at the bottom of the work box 5. The fixed blocks 82 are arranged on the top of each hydraulic rod 81. The fixed plates 83 are rectangular parallelepiped structures and are arranged horizontally on the opposite sides of the two fixed blocks 82. The transverse grooves 84 are arranged inside each fixed plate 83 and the openings are distributed opposite to each other. A plurality of grooves 85 are evenly arranged at the bottom of each transverse groove 84 and open upward. The pressure-bearing mold 86 is arranged between the two fixed plates 83. The fixed blocks 82 and the fixed plates 83 are integrally formed, and the grooves 85 are rectangular parallelepiped structures.

[0024] Specifically, the right-hand shock-absorbing pad 41 and fixed column 42 are located between the two cooling fans 2. The fixed columns 42 are T-shaped, with the force-removing plates 43 located on the upper, lower, front, and back surfaces of each fixed column 42, each facing the other, and slanted toward the center of the noise reduction mechanism 4. The sound-absorbing cotton block 47 is a flat-angled prism.

[0025] The pressure-bearing mold 86 includes a mold plate 861, several pressing grooves 862, anti-slip pads 863, several fixed arms 864, and several raised blocks 865. The pressing grooves 862 are evenly distributed on the top of the mold plate 861, the anti-slip pads 863 are located on the bottom of the mold plate 861, and several fixed arms 864 are located opposite each other at the left and right ends of the mold plate 861. Several raised blocks 865 are evenly distributed on the top of each fixed arm 864. The fixed arms 864 are rectangular parallelepiped structures, and the raised blocks 865 have the same structure as the grooves 85. The mold plate 861, the pressing grooves 862, the fixed arms 864, and the raised blocks 865 are integrally formed. The thickness of the fixed arms 864 and the raised blocks 865 is less than the height of the transverse groove 84.

[0026] This solution utilizes a fixing mechanism 8 and a control mechanism 9, allowing the pressure-bearing mold 86 to be transferred from the workbench 1 to the fixing mechanism 8 via the conveyor belt 2. Fixing arms 864 are provided on either side of the pressure-bearing mold 86, allowing it to fit into the transverse groove 84 as the conveyor belt 2 moves. Furthermore, when on the conveyor belt 2, the pressure-bearing mold 86 is slightly lower than the top of the transverse groove 84, and its bottom, including the bottom of the protruding block 865, is also higher than the bottom of the transverse groove 84. This ensures unimpeded movement of the pressure-bearing mold 86. The control mechanism 9 enables the hydraulic rod 81 to drive the fixing plate 83 and the pressure-bearing mold 86 upward, away from the conveyor belt 2, to prevent subsequent laminating operations from affecting the conveyor belt 2 and the workbench 1. Simultaneously, personnel only need to ensure the proper alignment of the pressure-bearing mold 86 at the rear end of the workbench 1. After each pressure-bearing mold 86 passes through a laser scanner 93, the controller 92 records the distance between each other, ensuring that each protruding block 865 of the pressure-bearing mold 86 precisely corresponds to each groove 85, ensuring a foolproof laminating operation. This solution greatly improves the working efficiency of the device and realizes work automation.

[0027] Working principle: First, the control machine 92 controls the conveyor belt 2 to start working, and then several pressure-bearing molds 86 are transferred to the conveyor belt 2 in turn through the existing front device, and the alignment state of the pressure-bearing mold 86 is confirmed. Then the pressure-bearing mold 86 follows the conveyor belt 2 to move until the fixed arm 864 is completely docked with the transverse groove 84. At this time, the conveyor belt 2 stops, because the laser scanner 93 scans the pressure-bearing mold 86, and calculates the corresponding distance value between the scanning point and the pressing point and the distance between the previously scanned pressure-bearing mold 86. This can ensure that even if the distance between each pressure-bearing mold 86 is different, the conveyor belt 2 will stop when each pressure-bearing mold 86 arrives under the pressing mold. Then the hydraulic rod 81 is controlled to rise, driving the fixed plate 83 to rise so that each groove 85 is connected with each protrusion 865, and then the pressure-bearing mold 86 is fixed and driven to move upward away from the conveyor belt 2. Then the hydraulic cylinder 6 is controlled to drive the pressing mold 7 to move downward to perform the pressing work. After pressing, the hydraulic rod 81 descends to release the pressure-bearing mold 86. Then the conveyor belt 2 continues to operate to take away the pressure-bearing mold 86 and allow the following pressure-bearing mold 86 to enter the pressing area to complete the pressing work.
