Description

Technical Field

[0001] The present invention relates to the field of CTP plate forming, and particularly to a product forming stability device for CTP plate production. Background Art

[0002] CTP (Computer-to-Plate) plates are a technology used for printing plate making. They are the technical carriers for directly making plates through computer data, replacing the traditional film plate-making process. They can achieve high-precision image reproduction, with a resolution usually reaching above 2400 dpi, suitable for fine printing. They mainly include thermal type, silver salt type, photopolymer type, and process-free type, among which the manufacturing process of thermal type CTP is the most common.

[0003] The manufacturing process of thermal type CTP plates mainly includes three steps: substrate pretreatment, coating solution preparation, and final plate manufacturing and processing. When finally completing the production of CTP plates, considering that CTP plates include photosensitive coatings, these materials are sensitive to light, moisture, temperature, and physical damage. Therefore, it is necessary to be moisture-proof, light-proof, dust-proof, and prevent mechanical damage. We need to package the CTP plates.

[0004] Currently, when packing, the CTP plates are manually divided and stacked, then the film is covered, and finally sealed with plastic tape. However, this method has a low degree of automation. The substrates of conventional CTP plates are rigid substrates (such as aluminum plates), that is, the conventional types do not have flexibility. However, for special requirements, the market has also developed plate variants with limited flexibility, taking into account the CTP plate-making efficiency and mild bending ability. Generally, polyester film (PET) can be used instead of aluminum plates. At this time, the flexibility of the CTP plates makes them easy to bend during handling, which may lead to irreversible damage to the plates and also restricts the difficulty of automatic stacking. Summary of the Invention

[0005] In order to solve the problems raised in the background art, the present invention is provided, and the following further elaborates on the present invention.

A guiding plate is also fixedly connected to the frame body. An upper sliding groove is provided on the guiding plate, and a lower sliding groove is provided on the side wall of the transfer box. The two ends of the upper sliding groove and the lower sliding groove are communicated to form an annular slideway. A rotating plate is provided on one side of the annular slideway close to the conveyor belt. One end of the rotating plate passes through the guiding plate through a rotating shaft, and the other end contacts the inclined groove wall of the lower sliding groove. A torsion spring is provided on the rotating shaft. The blocking member is rotatably connected to the mounting rod, and a second torsion spring is provided between the mounting rod and the blocking member. A flow channel is provided in the guiding member, an air port is provided on the surface of the guiding end facing the plate material, and the flow channel is communicated with an air pump. During the retraction process of the guiding member, the reaction force of the ejected air flow causes the guiding end of the guiding member to suspend above the plate material at a certain distance, achieving the purpose that the guiding end does not directly contact the plate material during retraction.

[0008] Preferably, an electric slide rail is provided on the frame body. A connecting arm is integrally provided on the side wall of the transfer box. The connecting arm is connected with an integrally formed straight rod. The straight rod passes through the slider of the electric slide rail. A first clamping block is connected to the end of the straight rod, and the first clamping block presses on the slider. When the transfer box is at a high position to receive the plate material, the first clamping block presses on the slider due to its own weight to achieve static at the high position. After reaching the target quantity, the electric slide rail operates, and the slider descends, bringing the transfer box to a low position.

[0009] Preferably, a sliding groove is provided on the side wall of the transfer box, and the bottom plate is slidably arranged at the sliding groove. A first screw rod is connected to the side wall of the transfer box. A screw sleeve is arranged on the first screw rod, and the screw sleeve is connected to both sides of the bottom plate. A first gear is connected to the end of the screw sleeve, and the first gear rotates synchronously with the first screw rod. A guide post is also connected to the connecting arm. A second clamping block is connected to the top of the guide post. An extension member is slidably arranged on the guide post. The extension member is fixedly connected to the slider of the electric slide rail. A spring is also sleeved on the guide post. The two ends of the spring respectively contact the extension member and the connecting arm. The extension member is connected with a first rack, and the first rack meshes with the first gear. The operation of the electric slide rail to lower the slider is divided into two stages. In the second stage, the bottom plate is driven to slide outwards in a linkage manner. The plate materials in the transfer box are blocked in the transfer box by the frame and fall on the packaging tooling under their own weight, thus completing the transfer of the stacked plate materials.

[0010] Preferably, the packaging tooling is slidably arranged on the frame body through feet. A second screw rod is also provided on the frame body. The packaging tooling is connected to the second screw rod through a second screw sleeve. A second gear is also provided on the second screw rod. The slider of the electric slide rail is also connected with a second rack through a connecting rod, and the second rack meshes with the second gear. The purpose is to enable the packaging tooling to automatically move below the transfer box when the transfer box descends and to automatically move outwards when the transfer box resets.

[0011] Preferably, the packaging tooling includes a storage box. The storage box is provided with sunk grooves on its symmetrical side walls, and a detachable bottom tray is provided at the sunk grooves. The distance between the bottom tray and the end of the storage box exceeds the stacking height of the single-packaging sheet material. The purpose is that when the transfer box is reset to its initial position, the bottom plate can retract into the transfer box, and the independent setting of the bottom tray can directly take away the bottom tray and the sheet materials stacked thereon.

[0012] Preferably, a plurality of adhesive wheels are provided at the bottom of the storage box, and the bottom tray is provided with avoidance grooves, and the tops of the adhesive wheels are exposed outside the avoidance grooves. The adhesive on the adhesive wheels can adhere to the packaging bags to position the packaging bags, and the packaging bags can be detached from the adhesive wheels without damage when the packaging tooling is moved out.

[0013] Preferably, a glue-releasing wheel is rotatably provided in the storage box, a tape is wound around the glue-releasing wheel, the free end of the tape is wound around the adhesive wheel, and the glue-releasing wheel is connected to the output shaft of a stepping motor. Before each placement of the packaging bag, the stepping motor drives the glue-releasing wheel to rotate by a certain angle so that a new pasting part of the tape is exposed.

[0014] Preferably, a sliding groove is provided on the storage box, the glue-releasing wheel is rotatably arranged on a sliding frame, the adhesive wheel is rotatably arranged on a fixed-length rod, the fixed-length rod is fixedly connected to the sliding frame, and the sliding frame is in sliding fit with the sliding groove; a guide post is provided in the sliding groove, the guide post penetrates through the sliding frame, and a second spring is sleeved outside the guide post, and the second spring is compressed between the sliding frame and the bottom of the sliding groove. When the stacked sheet materials fall into the storage box, the sheet materials press down the whole lifting part, and the adhesive wheels are no longer exposed outside the bottom tray, and the sheet materials are flat on the bottom tray to protect the sheet materials.

[0015] Preferably, cranks are connected to both ends of a rotating shaft that moves along with the conveyor belt. One end of the crank is rotatably connected to one end of a first connecting rod, the other end of the first connecting rod is rotatably connected to a second connecting rod, one end of the second connecting rod is rotatably connected to a third connecting rod, the third connecting rod is fixedly connected to a frame body, the other end of the second connecting rod is rotatably connected to one end of a fourth connecting rod, the other end of the fourth connecting rod is rotatably connected to a moving frame, and a sliding rod is also connected to the frame body, and the moving frame is slidably arranged on the sliding rod. By designing the lengths of the link mechanism, the moving frame can be controlled to reciprocate to cooperate with the conveyor belt to receive and release the sheet materials.

[0016] Advantageous effects: Compared with the prior art, the present invention has the following technical effects:

[0017] (1) The guide member allows the front end of the plate to undergo only a small deformation when it falls into the guide member, so that the plate can be transported at a normal speed to protect the plate; the blocking member fits the top surface of the guide member to prevent the plate from retreating when the guide member retreats, and then the plate falls to the transfer box below; the guide member is guided by an annular slide formed by the guide plate and the side wall of the transfer box, and a flow channel is provided in the guide member. The air flow blows from the air port of the plate to the stacked plates in the transfer box. The reaction force causes the guide end of the guide member to float a distance above the plate, so that the guide end does not directly contact the plate when retreating, thereby preventing the plate from being brought back and damaged.

[0018] (2) When the transfer box is transferred to the packaging tool, the transfer box descends and the packaging tool moves to the bottom of it. The plate in the transfer box can be transferred to the packaging tool through the two-stage descent of the slider; the packaging tool can pack the plate, and the packaging bag can be positioned in the storage box through the adhesive wheel. When the plate falls into the storage box, the lifting unit is pressed down, and the lifting unit compresses the second spring, so that the adhesive wheel is no longer exposed on the bottom support, and the plate is flat on the bottom support to protect the plate; the packaging tool can automatically change the adhesive position. Before placing the packaging bag each time, the stepper motor drives the adhesive wheel to rotate a certain angle to expose the new adhesive part of the tape.

[0019] (3) The crank, the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod constitute a connecting rod mechanism. By designing the length of the connecting rod mechanism, the movable frame can be controlled to move back and forth to cooperate with the conveyor belt to receive and release the plate.

Specific implementation mode

[0030] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the accompanying drawings.

[0031] A product forming and stabilizing device for CTP plate production, comprising a frame body 1, on which a conveyor belt 2 for conveying CTP plates (hereinafter referred to as plates) is provided. The plates to be packaged fall onto this conveyor belt 2 from top to bottom in the process, and then fall onto the transfer box 3 under the conveyance of the conveyor belt. A counter 4 is further provided on the frame body 1 to perform counting operations on the plates moving on the conveyor belt 2. When the counting quantity reaches a preset value, it is considered that the quantity of the plates currently falling onto the transfer box 3 reaches a single packing quantity. Then, the conveyor belt 2 pauses to convey the plates, and the plates in the current transfer box 3 are transferred and then packed.

[0032] As described in the background technology, the polyester-based CTP plate has a certain flexibility. When the plate moves to the end of the conveyor belt, the end that first extends outside the conveyor belt 2 will bend downward under its own weight. As the length of its extension increases, the end sags more, and the damage to the plate is obvious. At the same time, when half of the plate is suspended outside the conveyor belt, the center of gravity of the plate will no longer be on the conveyor belt, and the plate may even flip over. At present, by increasing the conveying rate of the conveyor belt, the plate has a higher speed when leaving the conveyor belt. The plate will detach from the conveyor belt under inertia and fall forward on the transfer box 3 to prevent the plate from flipping over. However, at this time, the friction between the plate initially falling on the conveyor belt and the conveyor belt is severe, which damages the plate. At the same time, the collision between the plates falling on the transfer box 3 under inertia may also cause damage, and the randomness of the falling position makes it impossible to regularize the plate falling on the transfer box 3, which needs to be further regularized.

[0033] In order to solve the problem of neatly stacking the plates on the transfer box 3, the present embodiment adopts the following technical solution: a guide 5 is provided under the conveyor belt 2, and the guide 5 is controlled to extend and receive the plate that is about to leave the conveyor belt. When the end of the plate moves outside the conveyor belt, the guide 5 is controlled to move forward synchronously to receive the end of the plate. In the process of the plate gradually leaving the conveyor belt, the guide 5 also moves forward synchronously until the plate completely leaves the conveyor belt and falls completely on the guide 5. Due to the existence of the guide 5, the plate does not fall directly on the transfer box 3, but first falls on the guide 5. The guide is close to the conveyor belt, so that the front end of the plate only undergoes a small deformation in the process of falling into the guide, and at this time the conveyor belt can also use a conventional speed to transport the plate to protect the plate.

[0034] The guide 5 acts as a transfer to transport the plate to the top of the transfer box 3. Then the guide 5 retreats and the plate falls directly on the transfer box 3. To prevent the plate from retreating with the guide 5, the frame 1 is connected with a mounting rod 6 located below the conveyor belt 2 and above the guide 5. The mounting rod 6 is connected with a blocking member 7, and the bottom of the blocking member 7 is in contact with the top surface of the guide 5. When the guide 5 retreats, based on the adhesion characteristics of the blocking member 7 and the guide, the blocking member 7 will prevent the plate from retreating with the guide and then falling to the transfer box 3 below.

[0035] When the guiding member 5 conveys the plate material, the distance between it and the transfer box 3 needs to be at the thickness of the number of plate materials stacked in one-time packaging on the transfer box 3. To eliminate the random position of the plate material when it falls into the transfer box 3, the following technical solution is adopted in this embodiment: One end of the guiding member 5 is rotatably connected to a moving frame 8, and the moving frame 8 is controlled to reciprocate to receive and release the plate material. The other end is a guiding end, and a sliding convex 501 is provided on its side; A guiding plate 9 is also fixedly connected to the frame body 1. An upper sliding groove 901 is provided on the guiding plate 9, and a lower sliding groove 301 is provided on the side wall of the transfer box 3. The two ends of the upper sliding groove 901 and the lower sliding groove 301 are connected to form an annular slideway. The width of the lower sliding groove 301 is set according to the thickness of the plate materials to be stacked in the transfer box 3; A rotating plate 10 is provided on one side of the annular slideway close to the conveyor belt. One end of the rotating plate 10 passes through the guiding plate 9 through a rotating shaft, and the other end contacts the inclined groove wall of the lower sliding groove 301. A torsion spring 11 is provided on the rotating shaft. The function of the torsion spring is to generate an elastic force that always presses the rotating plate 10 against the inclined groove wall of the lower sliding groove 301.

[0036] When the guiding member 5 conveys the plate material forward, the rotating plate 10 is pressed against the inclined groove wall of the lower sliding groove 301 under the elastic force of the torsion spring. The sliding convex 501 on the side of the guiding member 5 first passes over the rotating plate 10 and then enters the upper sliding groove 901 until the plate material is sent above the transfer box 3; Subsequently, the guiding end of the guiding member 5 falls into the connected lower sliding groove 301. At this time, the guiding member 5 is in an inclined state, and the plate material falls into the transfer box 3 along with the guiding end. Then the sliding convex 501 retracts along the lower sliding groove 301, and the plate material is gradually flattened in the transfer box 3 during the retraction process; When the sliding convex 501 moves along the inclined groove wall of the lower sliding groove 301, it pushes the rotating plate 10 away and then resets. Wait for the next cycle, and after the rotating plate 10 resets, the pushed-away rotating plate 10 is reset and pressed against the inclined groove wall of the lower sliding groove 301 under the elastic force of the torsion spring.

[0037] The blocking member 7 is rotatably connected to the mounting rod 6, and a second torsion spring 12 is provided between the mounting rod 6 and the blocking member 7. Its function is that when the guiding member 5 is in an inclined state during the moving process, the rotatably arranged blocking member 7 has a degree of rotational freedom and can always be pressed tightly against the guiding member 5 under the action of the second torsion spring 12.

[0038] During the retraction process of the guide member 5, the guiding end of the guide member 5 will press down on the plates stacked in the transfer box 3 under its own weight. On the one hand, to prevent the frictional force generated by the contact with the plates during retraction from causing displacement of the stacked plates, or even being taken out of the transfer box 3. On the other hand, to avoid irreversible damage to the plates caused by the friction between the guiding end and the plates, the present invention adopts an air suspension method, so that the guiding end of the guide member 5 floats above the plates without direct contact. The solution is as follows: A flow channel is provided in the guide member 5, and an air port 502 is provided on the side of the guiding end facing the plates. The flow channel communicates with the air pump 13. The air flow input by the air pump blows from the air port 502 of the plates onto the plates stacked in the transfer box 3, and the reaction force makes the guiding end of the guide member 5 float above the plates by a certain distance, achieving the purpose that the guiding end does not directly contact the plates during retraction.

[0039] The transfer box 3 is close to the conveyor belt and is used for intermediate transfer of the plates. After reaching the guaranteed quantity at one time, the transfer box 3 moves down to transfer the plates stacked therein to the packaging fixture. An electric slide rail 14 is provided on the frame body 1. A connecting arm 15 is integrally provided on the side wall of the transfer box 3. The connecting arm 15 is connected with a straight rod 16 integrally. The straight rod 16 penetrates through the slider 17 of the electric slide rail 14. And the end of the straight rod 16 is connected with a first clamping block 18, and the first clamping block 18 presses on the slider 17. When the transfer box 3 receives the plates at a high position, the first clamping block 18 presses on the slider 17 due to its own weight to achieve static at a high position. After reaching the target quantity, the electric slide rail 14 operates, and the slider 17 descends to bring the transfer box 3 to a low position.

[0040] The packaging fixture is located below the transfer box 3. When the transfer box 3 descends to a low position, the plates stacked therein can be automatically transferred to the packaging fixture. The specific solution is as follows: A chute is provided on the side wall of the transfer box 3, and a bottom plate 19 is slidably arranged at the chute. A first screw rod 20 is connected to the side wall of the transfer box 3. A screw sleeve 21 is arranged on the first screw rod 20, and the screw sleeve 21 is connected to both sides of the bottom plate 19; A first gear 22 is connected to the end of the screw sleeve 21, and the first gear 22 rotates synchronously with the first screw rod 20; A guide post 23 is also connected to the connecting arm 15. A second clamping block 24 is connected to the top of the guide post 23. An extension member 25 is slidably arranged on the guide post 23, and the extension member 25 is fixedly connected to the slider 17 of the electric slide rail 14. A spring 26 is also sleeved on the guide post 23, and both ends of the spring 26 respectively contact the extension member 25 and the connecting arm 15. The extension member 25 is connected with a first rack 27, and the first rack 27 meshes with the first gear 22.

[0041] The movement of the electric slide rail 14 to lower the slider 17 is divided into two stages: The first stage is the stage of the transfer box 3 descending. During this process, the slider 17 descends, and the transfer box 3 descends together with the slider 17 by its own weight. At this time, the first rack 27 and the first gear 22 do not engage in transmission until the transfer box 3 presses on the lower packaging fixture and ends; The second stage is the stage of the bottom plate 19 being pulled out. When the transfer box 3 presses on the lower packaging fixture and is in a stationary state, the electric slide rail 14 moves to make the slider 17 continue to descend. At this time, the first fixture block 18 is separated from the slider 17, and the extension piece 25 descends with the slider 17. While compressing the first spring 26, the first rack 27 descends and makes the first screw 20 rotate through the meshing action with the first gear 22. The rotating first screw 20 converts the rotation into the movement of the screw sleeve 21 through the cooperation with the screw sleeve 21, and then drives the bottom plate 19 to slide outwards. The plates in the transfer box 3 are blocked in the transfer box 3 by the frame and fall on the packaging fixture under their own weight, that is, the transfer of the stacked plates is completed.

[0042] After being transferred to the packaging fixture, the transfer box 3 is reset, and the packaging fixture can be removed to perform the packing operation independently. In this embodiment, the following technical solutions are adopted to make the packaging fixture automatically move under the transfer box 3 when the transfer box 3 descends and can automatically move outwards when the transfer box 3 is reset: The packaging fixture is slidably arranged on the frame 1 through the support feet 28. A second screw 29 is also provided on the frame 1. The packaging fixture is connected to the second screw 29 through the second screw sleeve 30. A second gear 31 is also provided on the second screw 29. The slider 17 of the electric slide rail 14 is also connected with a second rack 32 through a connecting rod, and the second rack 32 meshes with the second gear 31. In the first stage of the transfer box 3 descending, the meshing transmission between the second rack 32 and the second gear 31 makes the second screw 29 rotate, and the second screw sleeve 30 will drive the packaging fixture to move directly below the transfer box 3. When the first stage ends, the transfer box 3 just falls on the packaging fixture. At this time, the second rack 32 and the second gear 31 are disengaged from meshing; In the second stage, the second rack 32 continues to move down, but at this time the packaging fixture is stationary at the original position.

[0043] The packaging fixture includes a storage box 33. The storage box 33 is provided with a sunk groove on its symmetric side walls, and a detachable bottom tray 34 is provided at the sunk groove. The distance between the bottom tray 34 and the end of the storage box 33 exceeds the stacking height of the single-packaging plates. When the transfer box 3 presses down on the top of the storage box 33 and the bottom plate 19 slides outwards, the plates in the transfer box 3 fall on the bottom tray 34 in the storage box 33. And based on the fact that the stacking height of the single-packaging plates is less than the storage height of the storage box 33, the bottom plate 19 can retract into the transfer box 3 when the transfer box 3 is reset initially. Based on the independent setting of the bottom tray 34, the bottom tray 34 together with the stacked plates on it can be directly taken away.

[0044] The packaging tooling is used to package the stacked sheets it carries. In the initial state, the packaging bag is pre-placed on the bottom tray 34. After being flattened, the edge is located outside the storage box 33. The packaging bag then moves together with the packaging tooling to below the transfer box 3. To stabilize the position of the packaging bag, in this embodiment, the packaging bag is adhesively positioned. Specifically: multiple adhesive wheels 35 are provided at the bottom of the storage box 33, and the bottom tray 34 is provided with a clearance groove 341. The top of the adhesive wheel 35 is exposed outside the clearance groove 341. When the packaging bag needs to be placed, the adhesive on the adhesive wheel 35 can adhere to the packaging bag to position the packaging bag. After the packaging tooling is removed, the packaging bag can directly wrap the sheets. The adhesiveness of the adhesive is weak enough to meet the positioning of the packaging bag. Finally, the packaging bag and the bottom tray 34 are removed together, and the packaging bag can be detached from the adhesive wheel 35 without damage.

[0045] To reduce the workload of applying adhesive on the adhesive wheel 35 each time, this embodiment is implemented through the following solution: A glue-releasing wheel 36 is rotatably provided in the storage box 33. A tape is wound around the glue-releasing wheel 36, and the free end of the tape is wound around the adhesive wheel 35. The glue-releasing wheel 36 is connected to the output shaft of a stepping motor 37. The function of the glue-releasing wheel 36 is to expose the adhesive surface of the tape wound around the glue-releasing wheel 36 in the reverse direction. After each packaging, the adhesiveness of the exposed pasting part of the glue-releasing wheel 36 outside the bottom tray 34 decreases. Before each placement of the packaging bag, the stepping motor 37 drives the glue-releasing wheel 36 to rotate by a certain angle so that a new pasting part of the tape is exposed.

[0046] In the present invention, the adhesiveness of the tape is low, aiming not to damage the packaging bag when detaching from it. However, at this time, it is necessary to increase the surface area of the glue-releasing wheel 36 exposed outside the bottom tray 34 to increase the adhesion area. But this will cause the stacked sheets to be in a suspended state when they fall on the bottom tray 34, and there is a line contact between the bottommost sheet and the glue-releasing wheel 36. The strong pressure may damage the sheet. Therefore, in this embodiment, the entire rubber wheel assembly is arranged on an elastic member to achieve the purpose of protecting the sheet. Specifically: A sliding groove 331 is provided on the storage box 33. The glue-releasing wheel 36 is rotatably arranged on a sliding frame 38. The adhesive wheel 35 is rotatably arranged on a fixed-length rod 39. The fixed-length rod 39 is fixedly connected to the sliding frame 38. The sliding frame 38 is slidably matched with the sliding groove 331. A guiding column 40 is provided in the sliding groove 331. The guiding column 40 penetrates the sliding frame 38, and a second spring 41 is sleeved outside the guiding column 40. The second spring 41 is compressed between the sliding frame 38 and the bottom of the sliding groove 331.

[0047] The adhesive wheel 35, the glue releasing wheel 36, the stepping motor 37, the sliding frame 38 and the fixed-length rod 39 form a lifting unit. Before the stacked plates fall into the storage box 33, the lifting unit is at the highest position under the action of the second spring 41. At the highest position, part of the sliding frame 38 is stationary at the top position inside the chute 331, and the top surface of the adhesive wheel 35 is exposed outside the bottom support 34. When the stacked plates fall into the storage box 33, the plates press down the lifting unit, and the lifting unit compresses the second spring 41, so that the adhesive wheel 35 is no longer exposed outside the bottom support 34, and the plates are flat on the bottom support 34 to protect the plates.

[0048] As described above, one end of the guiding member 5 is rotatably connected to the moving frame 8, and the moving frame 8 is controlled to reciprocate to cooperate with the conveyor belt to receive and release the plates. This embodiment is realized by the linkage of a stable mechanical structure, and the solution is as follows: Cranks 43 are connected to both ends of the rotating shaft 42 that moves with the conveyor belt. One end of the crank 43 is rotatably connected to one end of the first connecting rod 44. The other end of the first connecting rod 44 is rotatably connected to the second connecting rod 45. One end of the second connecting rod 45 is rotatably connected to the third connecting rod 46. The third connecting rod 46 is fixedly connected to the frame body 1. The other end of the second connecting rod 45 is rotatably connected to one end of the fourth connecting rod 47. The other end of the fourth connecting rod 47 is rotatably connected to the moving frame 8. A sliding rod 48 is further connected to the frame body 1, and the moving frame 8 is slidably arranged on the sliding rod 48.

[0049] The crank 43, the first connecting rod 44, the second connecting rod 45, the third connecting rod 46 and the fourth connecting rod 47 form a connecting rod mechanism. The input of the connecting rod mechanism is the rotation of the crank 43 driven by the rotating shaft 42, and the output through the conduction of the connecting rod mechanism is converted into the linear displacement of the moving frame 8. By designing the lengths of the connecting rod mechanism, the moving frame 8 can be controlled to reciprocate to cooperate with the conveyor belt to receive and release the plates.

[0050] In the present invention, through the guiding member, only a small deformation occurs at the front end of the plate during the process of the plate falling into the guiding member, and the plate can be transported at a conventional speed to protect the plate; by blocking the 7 to fit the top surface of the guiding member 5, the plate is blocked from retreating when the guiding member 5 retreats, and then falls into the lower transfer box 3; through the annular slideway formed by the guiding plate 9 and the side wall of the transfer box 3, the guiding member 5 is guided. At the same time, a flow channel is provided in the guiding member 5, and the air flow blows from the air port 502 of the plate onto the stacked plates in the transfer box 3. The reaction force makes the guiding end of the guiding member 5 float above the plate by a certain distance, so that the guiding end does not directly contact the plate during retreat, preventing the plate from being taken back and damaged.

[0051] When the transfer box 3 is transported to the packaging tooling, the transfer box 3 descends and drives the packaging tooling to move to its lower part. Through the two-stage descent of the slider, the plates in the transfer box 3 can be transferred into the packaging tooling; the packaging tooling can perform a packing operation on the plates. The packaging bag can be positioned in the storage box 33 through the adhesive wheel 35. When the plates fall into the storage box 33, the lifting assembly is pressed downwards, and the lifting assembly compresses the second spring 41, so that the adhesive wheel 35 is no longer exposed outside the bottom tray 34, and the plates are flat on the bottom tray 34 to protect the plates; the packaging tooling can automatically change the adhesive position. Before each placement of the packaging bag, the stepping motor 37 drives the glue wheel 36 to rotate by a certain angle, so that the new pasting part of the tape is exposed.

[0052] The crank 43, the first connecting rod 44, the second connecting rod 45, the third connecting rod 46, and the fourth connecting rod 47 form a connecting rod mechanism. Through the design of the lengths of the connecting rod mechanism, the moving frame 8 can be controlled to reciprocate to cooperate with the conveyor belt to receive and release the plates.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
