Description

Technical Field

[0001] This invention relates to the field of plate presses, specifically to an automatic raw material feeding device for a plate press. Background Technology

[0002] A board press is a device used to press furniture panels, wooden doors, and various boards, as well as to level and shape furniture. It can make the bonding between boards stronger. It is mainly divided into screw type and hydraulic type. The former has a simple structure but is slow, while the latter has stable pressure and high efficiency. The basic structure includes a power system, control system, and actuators. It is widely used in woodworking, metal processing, building materials and other industries, and can handle tasks such as board bonding, metal stamping, and insulation board pressing.

[0003] The feeding process of a press is the step of conveying the material to be processed to the pressing station. There are two methods: manual and automated. Manual feeding is suitable for small batches and irregularly shaped parts. It relies on manual placement and alignment, which is less efficient. Automated feeding is completed by conveyor belts, robotic arms or pushing devices. When feeding, it is necessary to ensure that the material is flat and without deviation to avoid affecting the pressing quality.

[0004] Most sheet material is attracted to one end of the press machine using suction cups and then stacked. However, there is a certain gap when the material falls, causing some material to shift. This shifting can lead to localized over- or under-pressure, resulting in bubbles and cracks in the bonded sheets, affecting the quality of the finished sheets, and potentially damaging the equipment, increasing production costs and maintenance workload. In existing technology, workers stand on one side of the press machine and adjust the material after each set falls to ensure neat stacking, increasing their workload. Furthermore, if workers are still adjusting the material while the suction cups are being used, they may be injured while their hands are not in time. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an automatic material feeding device for a plate press, so as to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic material feeding device for a plate press, comprising a device body, an installation chamber, and an installation frame, wherein the installation chamber is provided at one end of the device body, and the installation frame is installed at the center end of the device body;

[0007] The device body has symmetrical first sliding grooves at the upper end. Limiting plates are movably installed inside the two sets of first sliding grooves. Multiple sets of second sliding grooves are symmetrically opened on the outer wall of the installation chamber. Installation plates are movably installed on the inner wall of the multiple sets of second sliding grooves. Push plates are installed on one end of the multiple sets of installation plates extending to the outer wall of the multiple sets of second sliding grooves.

[0008] Two sets of landing gears are movably mounted on the upper part of the main body of the device. Conveyor belts are movably mounted on the inner walls of both sets of landing gears. Two sets of hydraulic pumps are mounted on the upper part of the mounting frame. Hydraulic columns are mounted on the output ends of both sets of hydraulic pumps. Pressure plates are movably mounted on the inner wall of the mounting frame, and one end of each set of hydraulic columns is connected to the pressure plate.

[0009] By adopting the above technical solution, the problem of adjusting stacked sheet materials is solved. When the two sets of limiting plates move back and forth, they cooperate to push the sheet materials one by one to one side of the outer wall of the installation chamber, so that multiple sets of sheet materials are aligned at one end. When the two sets of push plates move back and forth, they cooperate to push the sheet materials to move, so that the sheet materials are stacked in the center. The two sets of limiting plates and the two sets of push plates work together to adjust multiple sets of sheet materials, improving the neatness of the stacked sheet materials and reducing the workload of the staff.

[0010] The invention is further configured such that multiple sets of retractable cylinders are movably installed inside the main body of the device, and toothed synchronous belts are respectively connected between the multiple sets of retractable cylinders.

One end of the multiple sets of telescopic columns is respectively connected to the bottom end of two sets of landing gears.

[0011] Preferably, the first motor starts, driving a set of retractable cylinders to rotate, and the multiple sets of retractable cylinders are connected to each other by toothed synchronous belts. As the multiple sets of retractable cylinders rotate, the inner walls of the multiple sets of retractable cylinders are threadedly connected to the outer walls of the multiple sets of telescopic columns. The multiple sets of telescopic columns move upward, thereby driving the two sets of landing gear to move upward.

[0012] The invention is further configured such that a conveyor roller is movably mounted at one end of each of the two sets of landing gears, and a conveyor gear is mounted at one end of each conveyor roller. An auxiliary roller is movably mounted at one end of each of the two sets of landing gears, and a toothed synchronous belt is provided between each of the two sets of auxiliary rollers and the conveyor rollers. The inner walls of both ends of the two sets of conveyor belts are movably connected to the outer walls of the two sets of auxiliary rollers and the outer walls of the conveyor rollers, respectively. A second motor is mounted inside the mounting compartment, and a first drive shaft is mounted at the output end of the second motor. A drive gear is mounted at one end of the first drive shaft, and the drive gear is meshed with the conveyor gear.

[0013] Preferably, the two sets of landing gears move upward, thereby driving the two sets of conveyor belts, conveyor rollers, two sets of auxiliary rollers, and stacked sheet material to move upward, so that the conveyor gear meshes with the drive gear. Then, the first motor is turned off, and the second motor is started, driving the first drive shaft to rotate, thereby driving the drive gear to rotate, driving the conveyor gear to rotate, and thus driving the conveyor roller to rotate. The conveyor rollers are connected to the two sets of auxiliary rollers through toothed synchronous belts. The rotation of the two sets of auxiliary rollers drives the two sets of conveyor belts to operate.

[0014] The invention is further configured such that a third motor is installed inside the main body of the device, a second drive shaft is installed at the output end of the third motor, two sets of drive bevel gears are installed on the outer wall of the second drive shaft, a first connecting shaft is movably installed inside multiple sets of second sliding grooves, and toothed synchronous belts are respectively provided between the multiple sets of first connecting shafts. The second drive shaft is respectively connected to two sets of first connecting shafts by toothed synchronous belts. Reciprocating thread grooves are opened on the outer wall of multiple sets of first connecting shafts, and protrusions on the inner wall of multiple sets of mounting plates are movably connected to multiple sets of reciprocating thread grooves.

[0015] Preferably, the third motor starts and drives the second drive shaft to rotate, thereby driving the two sets of drive bevel gears to rotate. The second drive shaft is connected to the two sets of first connecting shafts through toothed synchronous belts. The two sets of first connecting shafts rotate, and the reciprocating thread grooves on the outer wall of the multiple sets of first connecting shafts are movably connected to the protrusions on the inner wall of the multiple sets of mounting plates. One end of the multiple sets of mounting plates reciprocates inside the multiple sets of second sliding grooves.

[0016] The invention is further configured such that two sets of first transmission shafts are movably installed inside the main body of the device, and a transmission bevel gear is installed at one end of each set of first transmission shafts. The two sets of transmission bevel gears are respectively meshed with two sets of driving bevel gears. A second connecting shaft is movably installed inside each set of first sliding grooves. The two sets of second connecting shafts are respectively connected to the two sets of first transmission shafts by a toothed synchronous belt. A reciprocating thread groove is opened on the outer wall of each set of second connecting shafts. A movable seat is movably installed inside each set of first sliding grooves. The protrusions on the inner wall of each set of movable seats are respectively movably connected to the reciprocating thread grooves on the outer wall of each set of second connecting shafts. The two sets of movable seats are respectively movably connected to two sets of limiting plates.

[0017] Preferably, two sets of driving bevel gears rotate, and the two sets of driving bevel gears mesh with two sets of transmission bevel gears respectively. The two sets of transmission bevel gears rotate, thereby driving two sets of first transmission shafts to rotate. The two sets of first transmission shafts are connected to two sets of second connecting shafts through toothed synchronous belts. Therefore, the two sets of second connecting shafts rotate. The reciprocating thread grooves on the outer walls of the two sets of second connecting shafts are movably connected to the protrusions on the inner walls of the two sets of movable seats. Therefore, the two sets of movable seats reciprocate in the two sets of first sliding grooves, thereby driving the two sets of limiting plates to reciprocate.

[0018] The invention is further configured such that each of the two sets of limiting plates is equipped with a first limiting shaft at one end, and the two sets of first limiting shafts extend to the outer wall of the movable seat and are respectively equipped with a first limiting gear and a first limiting block. The inner walls on both sides of the two sets of first sliding grooves are respectively provided with a first reserved groove and a first limiting groove. Each of the two sets of first limiting grooves is provided with a first reserved hole at one end. The two sets of first limiting gears are respectively movably connected to the two sets of first reserved grooves, and the two sets of first limiting blocks are respectively movably connected to the two sets of first limiting grooves and the two sets of first reserved holes. The diameter of the two sets of first reserved holes is larger than the diameter of the two sets of first limiting blocks. A first toothed plate is movably installed at one end of each of the two sets of first reserved grooves, and a counterweight is provided inside each of the two sets of first toothed plates. Push rods are installed on the outer walls of the two sets of landing gears, and the two sets of push rods are respectively movably connected to the two sets of first toothed plates. The two sets of first toothed plates are respectively meshed with the two sets of first limiting gears.

[0019] Preferably, when the two sets of movable seats move within the two sets of first sliding grooves, the two sets of first limiting blocks move within the two sets of first limiting slots, and the two sets of first limiting gears move within the two sets of first reserved slots. The two sets of first limiting slots limit the two sets of first limiting blocks, thereby limiting the two sets of first limiting shafts. The two sets of first limiting blocks move into the two sets of first reserved holes. The limiting of the two sets of first limiting blocks is released, and the two sets of first limiting gears move to one end of the two sets of first reserved slots, so that the two sets of first limiting gears mesh with the two sets of first toothed plates. The two sets of landing gears move upward, driving the two sets of push rods to move upward. The two sets of push rods push the two sets of first toothed plates to move upward. The two sets of first toothed plates mesh with the two sets of first limiting gears, and the two sets of first limiting gears rotate, thereby driving the two sets of first limiting shafts to rotate. The two sets of first limiting shafts drive the two sets of limiting plates to flip.

[0020] The invention is further configured such that a support plate is installed on the upper end of the pressure plate, a second toothed plate and a third toothed plate are installed on the outer wall of the support plate, and the second toothed plate and the third toothed plate are staggered; a first movable shaft and a second movable shaft are movably installed inside the mounting frame; a first movable gear is installed on the outer wall of the first movable shaft, and the first movable gear is meshed with the second toothed plate; a second movable gear is installed on the outer wall of the second movable shaft, and the second movable gear is meshed with the third toothed plate; a first transmission gear is installed at both ends of the first movable shaft, and a second transmission gear is installed at both ends of the second movable shaft.

[0021] Preferably, the pressure plate moves downward, causing the support plate to move downward, which in turn causes the second and third toothed plates to move downward. The second and third toothed plates then mesh with the first and second movable gears, respectively. The second toothed plate first meshes with the first movable gear, which rotates, causing the first movable shaft to rotate, which in turn causes the two sets of first transmission gears to rotate. The support plate continues to move downward, causing the third toothed plate to mesh with the second movable gear, which rotates, causing the second movable shaft to rotate, which in turn causes the two sets of second transmission gears to rotate.

[0022] The invention is further configured such that: the upper end of the main body of the device is symmetrically provided with mounting grooves and docking grooves, and the two sets of mounting grooves correspond to the two sets of docking grooves respectively; the upper end of each of the two sets of mounting grooves is symmetrically provided with a third sliding groove; a third connecting shaft is movably mounted inside each of the two sets of third sliding grooves; and a toothed synchronous belt connects the two sets of third connecting shafts; a first speed-changing shaft is symmetrically mounted inside the mounting frame; and a toothed synchronous belt connects the two sets of first speed-changing shafts to the two sets of third connecting shafts respectively; a first speed-changing gear is mounted at one end of each of the two sets of first speed-changing shafts; and the two sets of first speed-changing gears are meshed with the two sets of first transmission gears respectively; the diameter of the two sets of first speed-changing gears is smaller than the diameter of the two sets of first transmission gears; a movable plate is movably mounted at the upper end of each of the two sets of mounting grooves; and two sets of sliders are mounted at the bottom end of each of the two sets of movable plates; and the inner walls of the multiple sets of sliders are threadedly connected to the outer walls of the multiple sets of third connecting shafts respectively.

[0023] Preferably, the first movable shaft rotates, thereby driving two sets of first transmission gears to rotate. The two sets of first transmission gears are respectively meshed with two sets of first speed-changing gears, so the two sets of first speed-changing gears rotate. Since the diameter of the two sets of first transmission gears is larger than the diameter of the two sets of first speed-changing gears, the rotational speed of the two sets of first speed-changing gears is greater than the rotational speed of the two sets of first transmission gears, thereby driving the two sets of first speed-changing shafts to rotate. The two sets of first speed-changing shafts are respectively connected to two sets of third connecting shafts through toothed synchronous belts. The two sets of third connecting shafts rotate, and multiple sets of third connecting shafts are connected to each other through toothed synchronous belts. The outer walls of the multiple sets of third connecting shafts are respectively threadedly connected to the inner walls of multiple sets of sliders, so the multiple sets of sliders are displaced inside the multiple sets of third sliding grooves, thereby driving the two sets of movable plates to move. One end of each set of movable plates moves into the two sets of docking grooves.

[0024] The invention is further configured such that auxiliary plates are movably mounted on the upper ends of both sets of movable plates, a second limiting shaft is mounted on one end of each set of auxiliary plates, a second limiting gear and a second limiting block are respectively mounted on both ends of the two sets of second limiting shafts, a second limiting groove and a second reserved groove are respectively provided on both sides of the two sets of mounting grooves, a second reserved hole is provided on one end of each set of second limiting grooves, the two sets of second limiting gears are movably connected to the two sets of second reserved grooves, and the two sets of second limiting blocks are respectively connected to the two sets of second limiting grooves and the two sets of second reserved holes.

[0025] Preferably, when the two sets of movable plates are displaced, they respectively drive the two sets of auxiliary plates to be displaced, which in turn drive the two sets of second limit gears and the two sets of second limit blocks to be displaced, and the two sets of second limit blocks respectively move into the two sets of second reserved holes.

[0026] The invention is further configured such that: two sets of second transmission shafts are movably mounted inside the mounting bracket; each set of second transmission shafts has a second transmission gear mounted at one end; the two sets of second transmission gears are respectively meshed with two sets of second transmission gears; the diameter of the two sets of second transmission gears is larger than the diameter of the two sets of second transmission gears; two sets of fourth connecting shafts are movably mounted inside the main body of the device; the two sets of fourth connecting shafts are respectively connected to the two sets of second transmission shafts by toothed synchronous belts; fourth toothed plates are movably mounted on the outer walls of the two sets of fourth connecting shafts; the inner walls of the fourth toothed plates are threadedly connected to the outer walls of the fourth connecting shafts; two sets of first reversing gears are movably mounted inside the main body of the device; the two sets of first reversing gears are respectively meshed with the two sets of fourth toothed plates; two sets of second reversing gears are movably mounted inside the main body of the device; the two sets of second reversing gears are respectively meshed with the two sets of first reversing gears; and the two sets of second reversing gears are respectively meshed with the two sets of second limiting gears.

[0027] Preferably, the second movable shaft rotates, thereby driving the two sets of second transmission gears to rotate. The two sets of second transmission gears are respectively engaged with the two sets of second speed-changing gears. The two sets of second speed-changing gears rotate, and since the diameters of the two sets of second transmission gears are larger than the diameters of the two sets of second speed-changing gears, the rotational speeds of the two sets of second speed-changing gears are greater than the rotational speeds of the two sets of second transmission gears. This drives the two sets of second speed-changing shafts to rotate. The two sets of second speed-changing shafts are respectively connected to the two sets of fourth connecting shafts via toothed synchronous belts. The two sets of fourth connecting shafts rotate, and their outer walls are threadedly connected to the inner wall of the fourth toothed plate. The fourth toothed plate is displaced and engages with the first reversing gear. The first reversing gear rotates and engages with the second reversing gear. The second reversing gear rotates and engages with the second limiting gear. The second limiting gear rotates, driving the second limiting shaft to rotate. The second limiting shaft drives the auxiliary plates to flip, causing the two sets of auxiliary plates to flip into the two sets of mounting slots.

[0028] In summary, the present invention has the following main beneficial effects:

[0029] This invention solves the problem of adjusting stacked sheet metal materials by setting up limiting plates and push plates. When the two sets of limiting plates move back and forth, they cooperate to push the sheet metal materials one by one to one side of the outer wall of the installation chamber, so that multiple sets of sheet metal materials are aligned at one end. When the two sets of push plates move back and forth, they cooperate to push the sheet metal materials to move, so that the sheet metal materials are stacked in the center. The two sets of limiting plates and the two sets of push plates work together to adjust multiple sets of sheet metal materials, improve the neatness of the stacked sheet metal materials, and reduce the workload of the staff.

[0030] This invention, by setting a first limiting block and a first limiting groove, allows two sets of movable seats to move within two sets of first sliding grooves, two sets of first limiting blocks to move within two sets of first limiting grooves, and two sets of first limiting gears to move within two sets of first reserved grooves. The two sets of first limiting grooves limit the two sets of first limiting blocks, thereby limiting the two sets of first limiting shafts. This prevents the two sets of limiting plates from flipping over during the process of pushing the material, which would affect the material placement and adjustment effect.

[0031] This invention, by incorporating a first limiting gear and a first toothed plate, allows two sets of landing gears to move upwards, thereby driving two sets of push rods to move upwards. These push rods then push two sets of first toothed plates upwards. The two sets of first toothed plates mesh with the two sets of first limiting gears, which rotate, causing two sets of first limiting shafts to rotate. These shafts then rotate the two sets of limiting plates, causing them to flip. The limiting plates then move into the two sets of first sliding grooves, preventing them from obstructing the stacked sheet material during movement.

[0032] This invention features movable plates and docking slots. Two sets of lifting frames move downwards, causing the stacked sheet material to fall onto the upper ends of the two movable plates at their respective ends. The two movable plates then move, with one end of each moving plate entering the two docking slots. This allows the two movable plates to cover the upper ends of the two conveyor belts, preventing the sheet material suspended above the two conveyor belts from being poorly compressed when under pressure, thus ensuring the quality of the sheet material pressing.

Each set of first drive shafts 30 has a drive bevel gear 31 mounted at one end, and the two sets of drive bevel gears 31 are respectively meshed with two sets of drive bevel gears 28. Each set of first sliding grooves 14 has a second connecting shaft 32 movably installed inside, and the two sets of second connecting shafts 32 are respectively connected to the two sets of first drive shafts 30 by toothed synchronous belts.

The two sets of movable seats 18 are movably connected to the two sets of limiting plates 19 respectively. The two sets of driving bevel gears 28 rotate and are meshed with the two sets of transmission bevel gears 31 respectively. The two sets of transmission bevel gears 31 rotate, thereby driving the two sets of first transmission shafts 30 to rotate. The two sets of first transmission shafts 30 are connected to the two sets of second connecting shafts 32 respectively through toothed synchronous belts. Therefore, the two sets of second connecting shafts 32 rotate. The reciprocating thread grooves on the outer wall of the two sets of second connecting shafts 32 are movably connected to the protrusions on the inner wall of the two sets of movable seats 18 respectively. Therefore, the two sets of movable seats 18 reciprocate in the two sets of first sliding grooves 14 respectively, thereby driving the two sets of limiting plates 19 to reciprocate.

[0068] Please see Figure 2 - Figure 17Each of the two sets of limiting plates 19 has a first limiting shaft 20 installed at one end. The two sets of first limiting shafts 20 extend to the outer wall of the movable seat 18 and are respectively equipped with a first limiting gear 21 and a first limiting block 22.

Each set of first toothed plates 34 is meshed with the two sets of first limiting gears 21. The two sets of movable seats 18 are located inside the two sets of first sliding grooves 14. During displacement, the two sets of first limiting blocks 22 move within the two sets of first limiting grooves 16, and the two sets of first limiting gears 21 move within the two sets of first reserved grooves 15. The two sets of first limiting grooves 16 limit the two sets of first limiting blocks 22, thereby limiting the two sets of first limiting shafts 20. The two sets of first limiting blocks 22 move into the two sets of first reserved holes 17, the limiting of the two sets of first limiting blocks 22 is released, and the two sets of first limiting gears 21 move to the two sets of first reserved holes 17. One end of a pre-reserved slot 15 allows two sets of first limiting gears 21 to mesh with two sets of first toothed plates 34 respectively. The two sets of landing gears 3 move upward, driving two sets of push rods 33 to move upward respectively. The two sets of push rods 33 push the two sets of first toothed plates 34 to move upward respectively. The two sets of first toothed plates 34 mesh with the two sets of first limiting gears 21 respectively. The two sets of first limiting gears 21 rotate, thereby driving the two sets of first limiting shafts 20 to rotate. The two sets of first limiting shafts 20 drive the two sets of limiting plates 19 to flip.

[0069] Please see Figure 18 - Figure 20A support plate 39 is installed on the upper end of the pressure plate 38. A second toothed plate 40 and a third toothed plate 41 are installed on the outer wall of the support plate 39, and the second toothed plate 40 and the third toothed plate 41 are staggered. A first movable shaft 42 and a second movable shaft 44 are movably installed inside the mounting frame 35. A first movable gear 43 is installed on the outer wall of the first movable shaft 42, and the first movable gear 43 is meshed with the second toothed plate 40. A second movable gear 45 is installed on the outer wall of the second movable shaft 44, and the second movable gear 45 is meshed with the third toothed plate 41. A first transmission gear 57 is installed at both ends of the first movable shaft 42, and a second transmission gear 61 is installed at both ends of the second movable shaft 44. The pressure plate 38 moves downward. 8 drives the support plate 39 to move downward, thereby driving the second toothed plate 40 and the third toothed plate 41 to move downward. The second toothed plate 40 and the third toothed plate 41 are respectively engaged with the first movable gear 43 and the second movable gear 45. The second toothed plate 40 first engages with the first movable gear 43. The first movable gear 43 rotates, driving the first movable shaft 42 to rotate, thereby driving the two sets of first transmission gears 57 to rotate. The support plate 39 continues to move downward, driving the third toothed plate 41 to engage with the second movable gear 45. The second movable gear 45 rotates, thereby driving the second movable shaft 44 to rotate, and then driving the two sets of second transmission gears 61 to rotate.

[0070] Please see Figure 2 - Figure 20The upper end of the main body 1 of the device is symmetrically provided with mounting grooves 46 and docking grooves 48, and the two sets of mounting grooves 46 correspond to the two sets of docking grooves 48 respectively. The upper end of each set of mounting grooves 46 is symmetrically provided with a third sliding groove 47. The third connecting shaft 60 is movably installed inside each set of third sliding grooves 47, and the two sets of third connecting shafts 60 are connected by a toothed synchronous belt. The mounting bracket 35 is symmetrically provided with first speed change shafts 58, and the two sets of first speed change shafts 58 are respectively connected to the two sets of third connecting shafts 60. The two sets of first transmission shafts 58 are connected by toothed synchronous belts. Each end of one set of first transmission shafts 58 is equipped with a first transmission gear 59, and each set of first transmission gears 59 meshes with one set of first transmission gears 57. The diameter of each set of first transmission gears 59 is smaller than the diameter of each set of first transmission gears 57. Movable plates 51 are movably mounted on the upper ends of each set of mounting slots 46. Two sets of sliders 52 are mounted on the bottom ends of each set of movable plates 51. The inner walls of multiple sets of sliders 52 are threadedly connected to the outer walls of multiple sets of third connecting shafts 60. The rotating shaft 42 drives the two sets of first transmission gears 57 to rotate. The two sets of first transmission gears 57 are respectively meshed with the two sets of first speed-changing gears 59, so the two sets of first speed-changing gears 59 rotate. Since the diameter of the two sets of first transmission gears 57 is larger than the diameter of the two sets of first speed-changing gears 59, the rotational speed of the two sets of first speed-changing gears 59 is greater than the rotational speed of the two sets of first transmission gears 57, thereby driving the two sets of first speed-changing shafts 58 to rotate. The two sets of first speed-changing shafts 58 are respectively connected to the two sets of third connecting shafts 60 through toothed synchronous belts. The two sets of third connecting shafts 60 rotate. Multiple sets of third connecting shafts 60 are connected to each other through toothed synchronous belts. The outer walls of multiple sets of third connecting shafts 60 are respectively threaded to the inner walls of multiple sets of sliders 52, so multiple sets of sliders 52 are respectively displaced inside multiple sets of third sliding grooves 47, thereby driving the two sets of movable plates 51 to move. One end of each set of movable plates 51 moves into the two sets of docking grooves 48.

[0071] Please see Figure 2 - Figure 24 Each of the two sets of movable plates 51 has an auxiliary plate 53 movably mounted on its upper end. Each of the two sets of auxiliary plates 53 has a second limiting shaft 54 ​​mounted on one end. Each of the two sets of second limiting shafts 54 has a second limiting gear 55 and a second limiting block 56 mounted on its two ends respectively. Each of the two sets of mounting slots 46 has a second limiting groove 49 and a second reserved groove 50 on its two sides respectively. Each of the two sets of second limiting grooves 49 has a second reserved hole 68 at one end. Each of the two sets of second limiting gears 55 is movably connected to each of the two sets of second reserved grooves 50 respectively. Each of the two sets of second limiting blocks 56 is connected to each of the two sets of second limiting grooves 49 and the two sets of second reserved holes 68 respectively. When the two sets of movable plates 51 move, they drive the two sets of auxiliary plates 53 to move, which in turn drives the two sets of second limiting gears 55 and the two sets of second limiting blocks 56 to move into the two sets of second reserved holes 68 respectively.

[0072] Please see Figure 7 - Figure 24 The mounting bracket 35 houses two sets of second transmission shafts 62, each with a second transmission gear 63 mounted at one end. These gears mesh with two sets of second transmission gears 61, the diameter of which is larger than that of the gears 63. The main body 1 houses two sets of fourth connecting shafts 64, each connected to a toothed synchronous belt between the second transmission shafts 62. Fourth toothed plates are movably mounted on the outer walls of each fourth connecting shaft 64. 65, and the inner wall of the fourth toothed plate 65 is threadedly connected to the outer wall of the fourth connecting shaft 64. Two sets of first reversing gears 66 are movably installed inside the main body 1 of the device, and the two sets of first reversing gears 66 are respectively meshed with the two sets of fourth toothed plates 65. Two sets of second reversing gears 67 are movably installed inside the main body 1 of the device, and the two sets of second reversing gears 67 are respectively meshed with the two sets of first reversing gears 66. The two sets of second reversing gears 67 are respectively meshed with the two sets of second limiting gears 55. The second movable shaft 44 rotates, thereby driving the two sets of second transmission gears. The first gear 61 rotates, and the two sets of second transmission gears 61 mesh with the two sets of second transmission gears 63 respectively. The two sets of second transmission gears 63 rotate, and since the diameters of the two sets of second transmission gears 61 are larger than the diameters of the two sets of second transmission gears 63, the rotational speed of the two sets of second transmission gears 63 is greater than the rotational speed of the two sets of second transmission gears 61. This drives the two sets of second transmission shafts 62 to rotate. The two sets of second transmission shafts 62 are connected to the two sets of fourth connecting shafts 64 via toothed synchronous belts. The two sets of fourth connecting shafts 64 rotate. The outer wall is threaded to the inner wall of the fourth toothed plate 65. The fourth toothed plate 65 is displaced and meshes with the first reversing gear 66. The first reversing gear 66 rotates and meshes with the second reversing gear 67. The second reversing gear 67 rotates and meshes with the second limiting gear 55. The second limiting gear 55 rotates, driving the second limiting shaft 54 ​​to rotate. The second limiting shaft 54 ​​drives the auxiliary plate 53 to flip, so that the two sets of auxiliary plates 53 flip into the two sets of mounting slots 46.

[0073] The working principle of this invention is as follows: When the operator uses the device to press the sheet material, the suction cups stack the sheet material one by one to one end of the main body 1 of the device. During the stacking of multiple sets of sheet material, the third motor 26 starts and drives the second drive shaft 27 to rotate, thereby driving the two sets of drive bevel gears 28 to rotate. The two sets of drive bevel gears 28 are respectively meshed with the two sets of transmission bevel gears 31. The two sets of transmission bevel gears 31 rotate, thereby driving the two sets of first transmission shafts 30 to rotate. The two sets of first transmission shafts 30 are respectively connected to the two sets of second connecting shafts 32 through toothed synchronous belts. Therefore, the two sets of second connecting shafts 32 rotate. The reciprocating thread grooves on the outer wall of the two sets of second connecting shafts 32 are respectively movably connected to the protrusions on the inner wall of the two sets of movable seats 18. Therefore, the two sets of movable seats 18 move back and forth in the two sets of first sliding grooves 14, thereby driving the two sets of limiting plates 19 to move back and forth.

[0074] When the two sets of limiting plates 19 move back and forth, the two sets of limiting plates 19 cooperate to push the sheet material one by one to one side of the outer wall of the installation chamber 2.

[0075] When the two sets of movable seats 18 move inside the two sets of first sliding grooves 14 respectively, the two sets of first limiting blocks 22 move inside the two sets of first limiting grooves 16 respectively, and the two sets of first limiting gears 21 move inside the two sets of first reserved grooves 15 respectively. The two sets of first limiting grooves 16 limit the two sets of first limiting blocks 22 respectively, thereby limiting the two sets of first limiting shafts 20, avoiding the two sets of limiting plates 19 from flipping during the process of pushing the material, which would affect the material placement and adjustment effect.

[0076] When the second drive shaft 27 rotates, it is connected to the two sets of first connecting shafts 29 via toothed synchronous belts. The two sets of first connecting shafts 29 rotate, and the reciprocating threaded grooves on the outer walls of the multiple sets of first connecting shafts 29 are movably connected to the protrusions on the inner walls of the multiple sets of mounting plates 24. One end of the multiple sets of mounting plates 24 moves back and forth inside the multiple sets of second sliding grooves 23, thereby driving the two sets of push plates 25 to move back and forth. The two sets of push plates 25 cooperate to push the sheet material to move, so that the sheet material is stacked in the center.

[0077] After the multiple sets of sheet material are adjusted, the third motor 26 is turned off, and the two sets of push plates 25 and the two sets of limiting plates 19 are respectively placed at one end of the outer wall of the multiple sets of sheet material. At this time, the two sets of first limiting blocks 22 move into the two sets of first reserved holes 17 respectively, the two sets of first limiting blocks 22 are released, and the two sets of first limiting gears 21 move to one end of the two sets of first reserved slots 15 respectively, so that the two sets of first limiting gears 21 mesh with the two sets of first tooth plates 34 respectively.

[0078] When the third motor 26 is turned off, the first motor 8 starts, driving a set of shrink cylinders 9 to rotate. Multiple sets of shrink cylinders 9 are connected by toothed synchronous belts. As they rotate, the inner walls of the multiple sets of shrink cylinders 9 are threadedly connected to the outer walls of multiple sets of telescopic columns 10. The telescopic columns 10 move upwards, thereby driving the two sets of landing gears 3 to move upwards, which in turn drives the two sets of conveyor belts 4, conveyor rollers 5, two sets of auxiliary rollers 7, and the stacked sheet material to move upwards, causing the conveyor gear 6 to mesh with the drive gear 13. Then, the first motor 8 is turned off, and the first motor 8 starts... The second motor 11 drives the first drive shaft 12 to rotate, which in turn drives the drive gear 13 to rotate, which in turn drives the conveying gear 6 to rotate, which in turn drives the conveying roller 5 to rotate. The conveying roller 5 is connected to the two sets of auxiliary rollers 7 through toothed synchronous belts. The rotation of the two sets of auxiliary rollers 7 drives the two sets of conveyor belts 4 to operate, thereby moving the sheet material. The sheet material is moved after being raised, which avoids the bottom sheet material from contacting the outer wall of the device body 1 and improves the stability of the stacked sheet material during movement.

[0079] When the two sets of landing gear 3 move upward, they drive the two sets of push rods 33 to move upward respectively. The two sets of push rods 33 push the two sets of first toothed plates 34 to move upward respectively. The two sets of first toothed plates 34 mesh with the two sets of first limiting gears 21 respectively. The two sets of first limiting gears 21 rotate, thereby driving the two sets of first limiting shafts 20 to rotate. The two sets of first limiting shafts 20 drive the two sets of limiting plates 19 to flip. The two sets of limiting plates 19 move into the two sets of first sliding grooves 14 respectively, avoiding the two sets of limiting plates 19 from obstructing the stacked sheet material during the movement.

[0080] The stacked sheet material continues to move. After the stacked sheet material moves to the lower end of the pressure plate 38, the second motor 11 is turned off, the stacked sheet material stops moving, the first motor 8 is started, and the two sets of lifting frames 3 move downward, so that the two ends of the stacked sheet material fall onto the upper ends of the two sets of movable plates 51 respectively.

[0081] After the stacked sheet material falls, the two sets of hydraulic pumps 36 start, driving the two sets of hydraulic columns 37 to move downward, which in turn drives the pressure plate 38 to move downward. The pressure plate 38 drives the support plate 39 to move downward, thereby driving the second toothed plate 40 and the third toothed plate 41 to move downward. The second toothed plate 40 and the third toothed plate 41 are respectively meshed with the first movable gear 43 and the second movable gear 45.

[0082] When the support plate 39 moves downward, the second toothed plate 40 first engages with the first movable gear 43. The first movable gear 43 rotates, driving the first movable shaft 42 to rotate, which in turn drives the two sets of first transmission gears 57 to rotate. The two sets of first transmission gears 57 are respectively engaged with the two sets of first speed-changing gears 59, so the two sets of first speed-changing gears 59 rotate. Since the diameter of the two sets of first transmission gears 57 is larger than the diameter of the two sets of first speed-changing gears 59, the rotational speed of the two sets of first speed-changing gears 59 is greater than the rotational speed of the two sets of first transmission gears 57, thereby driving the two sets of first speed-changing shafts 58 to rotate.

[0083] When the two sets of first speed-changing shafts 58 rotate, the two sets of first speed-changing shafts 58 are connected to the two sets of third connecting shafts 60 through toothed synchronous belts. When the two sets of third connecting shafts 60 rotate, multiple sets of third connecting shafts 60 are connected to each other through toothed synchronous belts. When multiple sets of third connecting shafts 60 rotate, the outer walls of multiple sets of third connecting shafts 60 are threadedly connected to the inner walls of multiple sets of sliders 52. Therefore, multiple sets of sliders 52 are displaced inside multiple sets of third sliding grooves 47, thereby driving the two sets of movable plates 51 to move. One end of each set of movable plates 51 moves into the two sets of docking grooves 48, so that the two sets of movable plates 51 cover the upper ends of the two sets of conveyor belts 4. This avoids poor pressure effect on the material suspended in the upper area of ​​the two sets of conveyor belts when the material is pressed, which would affect the pressing quality of the material.

[0084] When the two sets of movable plates 51 move, they drive the two sets of auxiliary plates 53 to move. The two sets of auxiliary plates 53 assist in adjusting the stacked board materials to prevent the bottom board materials from shifting during the movement of the two sets of movable plates 51.

[0085] When the two sets of movable plates 51 move, they drive the two sets of second limit gears 55 and the two sets of second limit blocks 56 to move. The two sets of second limit blocks 56 move into the two sets of second reserved holes 68 respectively. At the same time, the two sets of second limit gears 55 mesh with the two sets of second reversing gears 67.

[0086] The support plate 39 continues to move downward, causing the third toothed plate 41 to mesh with the second movable gear 45. The second movable gear 45 rotates, thereby driving the second movable shaft 44 to rotate, which in turn drives the two sets of second transmission gears 61 to rotate. The two sets of second transmission gears 61 mesh with the two sets of second speed-changing gears 63 respectively. The two sets of second speed-changing gears 63 rotate, and since the diameter of the two sets of second transmission gears 61 is larger than the diameter of the two sets of second speed-changing gears 63, the rotational speed of the two sets of second speed-changing gears 63 is greater than the rotational speed of the two sets of second transmission gears 61, thereby driving the two sets of second speed-changing shafts 62 to rotate.

[0087] When the two sets of second transmission shafts 62 rotate, they are connected to the two sets of fourth connecting shafts 64 via toothed synchronous belts. The outer walls of the two sets of fourth connecting shafts 64 are threaded to the inner walls of the fourth toothed plate 65, causing the fourth toothed plate 65 to shift and mesh with the first reversing gear 66. The first reversing gear 66 rotates and meshes with the second reversing gear 67. The second reversing gear 67 rotates and meshes with the second limiting gear 55. The second limiting gear 55 rotates, causing the second limiting shaft 54 ​​to rotate. The second limiting shaft 54 ​​causes the auxiliary plates 53 to flip, allowing the two sets of auxiliary plates 53 to flip into the two sets of mounting slots 46, preventing the two sets of auxiliary plates 53 from obstructing the downward movement of the pressure plate 38. The pressure plate 38 continues to move downward, pressing the stacked sheet material together.
