Description

Technical Field

[0001] This invention relates to the field of material conveying technology, specifically to a material conveying equipment and method for packaging paper product processing. Background Technology

[0002] In the processing and production of packaging paper products (such as cartons and cardboard), conveyor systems are typically used to transport materials between various processes (such as printing, die-cutting, gluing, and packaging). Automatic positioning, reversing, and alignment of materials during conveying are crucial to the smoothness and continuity of the entire material conveying system. Traditional material handling relies heavily on single belt conveyor translation or manual handling. However, to meet the diverse loading and unloading requirements of modern high-speed packaging production lines, online conveyor-assisted reversing and alignment devices that can directly adjust the position, reposition, and adjust the spacing of materials above the conveyor line are gradually becoming an indispensable part of continuous packaging material conveying.

[0003] However, existing auxiliary reversing and alignment devices for conveyor lines mostly use side baffle pushing or simple pneumatic side clamping, which have significant shortcomings when handling lighter and taller packaged paper products. On the one hand, simple side clamping, when lifting paper products off the conveyor belt for suspended reversing and transfer, is prone to tipping and falling due to the lack of a bottom support mechanism, especially when the clamping force is too large, which can easily cause the carton to deform and crush. On the other hand, existing conveying auxiliary equipment usually cannot simultaneously achieve flexible adjustment of the spacing between paper products (i.e., variable spacing alignment) during the clamping and transfer process, and lacks a precise horizontal rotation reversing function that matches the direction of the conveyor line. This results in poor versatility of the equipment when connecting upstream and downstream conveyors with different widths and feeding directions, often requiring manual intervention to stop the machine for adjustment, which seriously restricts the continuous flow efficiency of the material conveying system. Summary of the Invention

[0004] The purpose of this invention is to provide a material conveying device for packaging paper product processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a material conveying device for packaging paper product processing, comprising: A fixed outer frame is installed across and above the conveyor belt, serving as a fixed support foundation for the equipment. The lifting inner frame is slidably disposed inside the fixed outer frame and can reciprocate along the length of the conveyor belt to connect different process stations. A support plate is slidably connected to its inner side. The mounting bracket is movably connected to the underside of the support plate via a pivot, and is used to adjust the flow direction when transferring materials; A pair of mounting plates are symmetrically and movably mounted on the mounting frame, and are capable of horizontal movement toward or away from each other; A plurality of clamping rods are arranged in a linear array along the bottom of each mounting plate for contacting and positioning the paper product from the side; Each of the clamping rods has a rotatable support rod at its bottom, which is used to rotate downward to support the bottom of the paper product after the paper product has been clamped and raised to detach from the conveyor belt surface; A control component, fixedly mounted on the mounting frame, is used to drive the two mounting plates to move closer to each other synchronously, thereby driving the clamping rod to firmly clamp the paper product. The spacing adjustment component is independently provided on each of the mounting plates to adjust the horizontal spacing between adjacent clamping rods to accommodate paper products of different widths and to perform variable spacing alignment during the conveying process; The rotating assembly is independently provided on each of the mounting plates, and is used to drive the support rod to rotate, thereby changing the extension state of the support rod to support or release the paper product.

[0006] Furthermore, the mounting bracket specifically includes: The guide frame, in which the mounting plates are all horizontally slidably disposed, provides guiding support for the movement of the mounting plates; A connecting frame is fixedly connected to the top center of the guide frame, and its top is rotatably connected to the support plate via a pivot. A pair of support bars are symmetrically fixedly connected to the top two sides of the guide frame, providing a mounting base for the control assembly; Several guide rods are horizontally fixedly connected to the inside of the guide frame and move through the top extension end of the mounting plate.

[0007] Furthermore, linear guide rails are fixedly connected to both sides of the inner side of the fixed outer frame. The linear guide rails extend along the length of the conveyor belt, and the lifting inner frame slides through the linear guide rails to achieve translational feeding along the conveying direction. A pair of electric push cylinders are fixedly connected to the lifting inner frame, and the telescopic rod of the electric push cylinder is fixedly connected to the top of the support plate to drive the clamping mechanism to lift and disengage from the conveyor belt. A control motor is fixedly connected to the top of the support plate, and the output end of the control motor is connected to the rotating shaft of the connecting frame for driving the mounting frame to rotate horizontally to adjust the conveying direction of the paper products.

[0008] Furthermore, the control component includes: The control lever is rotatably connected to the middle position of the guide frame. Its outer side is provided with symmetrical threads of opposite directions. The control lever passes through the top of both mounting plates and is threadedly connected to the two mounting plates respectively. A driving component is fixedly disposed between the guide frame and the support bar, and is used to provide rotational power to drive the control rod to rotate, so that the two mounting plates can move closer to each other or further apart through threaded engagement.

[0009] Furthermore, the driving element includes: The worm gear is coaxially and fixedly connected to the middle position of the control lever; The worm gear is rotatably connected between the two support bars and meshes with the worm wheel to form a self-locking transmission structure; A servo motor is fixedly connected to the outside of one of the support bars, and its output end is connected to the end of the worm gear for transmission. It is used to precisely control the rotation angle of the worm gear and prevents the clamping force from failing when the power is off through a self-locking structure.

[0010] Furthermore, the mounting plate includes a plate body and a pair of support rods fixedly connected to its bottom two sides; The plate has seven drive slots running through it along its length. One of the drive slots in the middle is vertical, while the other drive slots, which are symmetrically distributed on both sides of the middle, are inclined to guide the expansion or contraction of the clamping rod. Each of the clamping rods has a longitudinally penetrating control groove; The spacing adjustment component includes: The top of each clamping rod is movably connected to the movable column via a control groove, and the middle section of the movable column is movably connected through the corresponding drive groove to provide displacement buffering and motion guidance. A pair of guide bars are fixedly connected to one side wall of the plate and move through the rods of all the clamping rods to guide the clamping rods to move horizontally. An adjusting element, disposed on one side of the plate, is used to provide longitudinal driving force to control the movement of all the movable columns along the extension direction of the drive groove.

[0011] Furthermore, the adjusting member includes: An adjustment frame is movably disposed on the side of the plate away from the guide bar. The section of the movable column away from the clamping rod is movably engaged with the inner side of the adjustment frame. The two ends of the adjustment frame are longitudinally slidably engaged with the guide grooves preset on both sides of the plate. A pair of hydraulic cylinders are fixedly connected to the top of the plate, and the ends of their telescopic rods are fixedly connected to the top of the adjustment frame. The extension and retraction of the hydraulic cylinders drive the adjustment frame to rise and fall, thereby driving the movable column to move within the drive groove to change the spacing distribution of the clamping rods.

[0012] Furthermore, the bottom of the clamping rod is constructed with a downward-opening receiving groove, and the bottom of the clamping rod has a Y-shaped forked structure; The tail end of the support rod is fixedly connected to a sleeve, which is rotatably connected inside the receiving groove. The main body of the support rod has an L-shaped structure, and the tail end of the support rod can be rotatably stored in the receiving groove to avoid interfering with the operation of the conveyor belt. The bottom surface of the clamping rod and the surface of the support rod are both linearly arrayed with friction strips to increase friction. The rotating assembly is mounted on the two support rods and is used to control the synchronous rotation of all the sleeves through the transmission structure, thereby synchronously changing the angular position of all the support rods.

[0013] Furthermore, the rotating assembly includes: A rotating rod, whose two ends are respectively rotatably connected to the bottom ends of the two support rods, has a polygonal cross-section at its middle end, and the rotating rod movably passes through the sleeve at the bottom of all the clamping rods to drive the sleeve to rotate; Synchronous pulley one, both ends of the rotating rod are fixedly connected to the synchronous pulley one; A pair of synchronized pulleys are movably connected to the internal cavity of the support rod via rotating shafts; A timing belt is provided inside each of the support rods, and the timing belt is tensioned and sleeved on the outside of the first timing pulley and the second timing pulley to form a stable transmission structure; Servo motor two is fixedly connected to the outer wall of one of the support rods, and its output end extends into the interior of the support rod and is connected to the shaft of one of the synchronous pulleys two for transmission, so as to provide the driving force for the rotation of the support rod. A method for conveying materials in the processing of packaging paper products includes the following steps: S1. After the paper product is fed into the lower part of the equipment by the upstream conveyor belt, the lifting inner frame moves along the linear guide rail of the fixed outer frame to align the clamping mechanism with the paper product. Then, the electric push cylinder drives the support plate to descend, so that the clamping rods on both sides are located on both sides of the paper product. S2. Once the servo motor of the control component starts, it drives the control lever to rotate, causing the two mounting plates to move closer to each other, so that the clamping rod clamps the paper product from the side. S3. When the paper product is clamped, the electric push cylinder retracts, driving the support plate and clamping mechanism to rise a certain distance, so that the bottom of the paper product is removed from the surface of the conveyor belt. At this time, the servo motor of the rotating component starts, drives the rotating rod to rotate, and drives all the support rods to rotate downward and extend synchronously, lifting the bottom of the paper product. S4. When the orientation of the mounting bracket needs to be adjusted, the control motor at the top of the support plate drives the mounting bracket to rotate horizontally to the angle required for the next station. If the column spacing needs to be adjusted, the hydraulic cylinder of the spacing adjustment component changes the spacing of the clamping rods to perform variable spacing alignment. S5. After adjustment, the lifting inner frame moves horizontally along the linear guide rail to directly above the downstream conveyor belt. The electric push cylinder descends to bring the paper product close to the downstream conveyor belt. The reverse operation of the rotating component retracts the support rod, and the reverse operation of the control component releases the clamping rod. The paper product can then fall smoothly onto the downstream conveyor belt, completing one cross-process transfer and alignment operation.

[0014] Compared with existing technologies, this material conveying equipment for packaging paper products has the following advantages: I. This invention, by rotating a support rod at the bottom of the clamping rod and controlling its rotation with a rotating component, allows the support rod to rotate to the bottom of the paper product to support it after the device clamps and lifts the paper product from the side of the conveyor belt. This forms a dual anti-tipping protection mode of side clamping and bottom support, solving the problem that traditional simple side clamping can easily cause paper products to tip over and fall due to center of gravity shift or start-stop inertia when suspended across the line. This effectively ensures the stability and safety of material transfer between conveyor lines.

[0015] Second, this invention achieves stepless adjustment of the horizontal distance between adjacent clamping rods by independently setting a spacing adjustment component on each mounting plate and using a hydraulic cylinder to drive the adjustment frame to rise and fall. This is combined with the linkage between the inclined drive groove guide and the movable column. This allows the equipment to flexibly adjust the clamping contact point according to the actual width of the paper products, ensuring uniform distribution of clamping force to prevent the carton from being crushed. At the same time, it enables synchronous variable-distance alignment of multiple groups of paper products during the conveying process, improving the versatility of the equipment when connecting upstream and downstream conveyor lines of different widths.

[0016] Third, this invention, by setting up a lifting, translation and rotation mechanism composed of linear guide rails, electric push cylinders, support plates and control motors, enables the equipment to move and feed materials along the length of the conveyor belt to connect different workstations. At the same time, it can drive the clamping mechanism to rotate horizontally to adjust the flow orientation of paper products. This achieves precise reversal and smooth transition of paper products between multiple conveyor lines or processes with different feeding directions, reduces downtime for manual intervention and adjustment, and significantly improves the continuous flow efficiency of the entire conveying system.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-9As shown, the present invention provides a technical solution: a material conveying device for packaging paper products. The device is installed horizontally above the conveyor belt 3 of the packaging production line. It is mainly used for the flow, reversal, and variable spacing alignment of materials between processing steps on the conveyor line. As an online auxiliary transfer and alignment device of the conveyor system, its core advantage is that it can lift the paper products off the surface of the conveyor belt 3 during the process of the conveyor belt 3, and perform side flexible clamping, bottom support to prevent tipping, variable spacing alignment, and horizontal rotation to adjust the orientation. This achieves a smooth transition and precise flow of paper products between different process stations, solving the problems of easy deviation and tipping of cartons at the end of the traditional conveyor line or at the line change point, as well as the low efficiency of manual handling. The conveying device mainly includes a fixed outer frame 1, a lifting inner frame 2, a mounting frame 4, a pair of mounting plates 5, several clamping rods 6, support rods 7, control components 8, spacing adjustment components 9, and rotating components 10.

[0021] The fixed outer frame 1 is fixedly mounted across the conveyor belt 3, serving as the fixed support foundation for the entire equipment. Linear guide rails 11 are fixedly connected to both sides of the inner side of the fixed outer frame 1, extending along the length of the conveyor belt 3. The lifting inner frame 2 is slidably mounted inside the fixed outer frame 1. Through the sliding cooperation between the sliders on both sides of the lifting inner frame and the linear guide rails 11, the lifting inner frame 2 can move and feed materials along the conveying direction, flexibly connecting different upstream and downstream workstations. A pair of electric push cylinders 12 are fixedly connected to the lifting inner frame 2, with the telescopic rods of the electric push cylinders 12 pointing vertically downwards and connected to the support plate 20. The top is fixedly connected to the support plate 20, which is slidably connected to the inner side of the lifting inner frame 2. When the electric push cylinder 12 extends or retracts, it drives the support plate 20 and the clamping mechanism below it to rise and fall, so that the clamped paper products can be lifted off the surface of the conveyor belt 3, freeing up key operating space for the intervention of the bottom support mechanism and the switching of the conveyor belt 3. The top of the support plate 20 is fixedly connected to the control motor 13, and the output end of the control motor 13 is connected to the rotating shaft of the connecting frame 402 for driving the mounting frame 4 to rotate horizontally, thereby adjusting the flow direction of the paper products when transferring materials to meet the needs of different feeding directions.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 9As shown, the mounting bracket 4 is movably connected to the bottom of the support plate 20 via a pivot. The mounting bracket 4 specifically includes a guide frame 401, a connecting frame 402, a pair of support bars 403, and several guide rods 404. The connecting frame 402 is fixedly connected to the top center of the guide frame 401, and its top is rotatably connected to the pivot of the support plate 20. The pair of support bars 403 are symmetrically fixedly connected to the top two sides of the guide frame 401, providing a stable mounting base for the control component 8. Several guide rods 404 are horizontally fixedly connected to the inside of the guide frame 401 and movably extend through the top extension of the mounting plate 5, providing precise guiding support for the movement of the mounting plate 5, ensuring that it remains horizontal during movement and does not shift or tilt.

[0023] A pair of mounting plates 5 are symmetrically and movably mounted on the mounting frame 4, and can move horizontally in opposite directions. The mounting plate 5 includes a plate body 14 and a pair of support rods 15 fixedly connected to its bottom two sides. Seven drive slots 16 are opened through the plate body 14 along the length direction. The drive slot 16 located in the middle is vertically arranged, and the remaining drive slots 16 symmetrically distributed on both sides of the middle are inclined. These inclined drive slots 16 form a guide rail for spacing adjustment, which is used to guide the expansion or contraction of the clamping rods 6. Each clamping rod 6 is longitudinally opened with a control slot 17 to provide displacement buffer and motion guidance in motion transmission.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the control component 8 is fixedly mounted on the mounting frame 4 and is used to drive the two mounting plates 5 to move closer to each other synchronously, thereby driving the clamping rod 6 to firmly clamp the paper product. The control component 8 includes a control rod 801 and a driving component. The control rod 801 is rotatably connected to the middle position of the guide frame 401 along the center line. Its outer side is provided with symmetrical threads with opposite directions of rotation. The control rod 801 passes through the top of both mounting plates 5 and is threadedly connected to both mounting plates 5 respectively. The driving component is fixedly mounted between the guide frame 401 and the support bar 403 and is used to provide rotational power to drive the control rod 801 to rotate. Through threaded engagement, the two mounting plates 5 move closer to each other or further apart. The driving component specifically includes a worm gear 802, a worm 803, and a servo motor 804. The worm gear 802 is coaxially fixedly connected to the middle position of the control rod 801; the worm 803 is rotatably connected between the two support bars 403 and meshes with the worm gear 802 to form a self-locking transmission. Structure: A servo motor 804 is fixedly connected to the outside of one of the support bars 403, and its output end is connected to the end of the worm gear 803 for transmission. It is used to precisely control the rotation angle of the worm gear 803. During operation, the servo motor 804 drives the worm gear 803 to rotate, and the worm gear 803 drives the worm wheel 802 and the control rod 801 to rotate. Since the threads on both sides of the control rod 801 rotate in opposite directions, the two mounting plates 5 will move towards the middle or separate to the sides synchronously under the drive of the threads. It is important to emphasize that the self-locking property of the meshing transmission between the worm wheel 802 and the worm gear 803 is crucial for the conveying operation. When the equipment lifts the paper product and suspends it in the air, the weight of the paper product will generate a huge external support force on the clamping mechanism. If ordinary gear or belt transmission is used, it is very easy to loosen when the power is cut off. However, the self-locking structure adopted in this application can prevent the clamping force from failing when the servo motor 804 is powered off, avoid the mounting plate 5 from loosening due to external support, and eliminate the safety hazard of falling during transportation.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, several clamping rods 6 are the core components of this equipment that directly contact the paper products. Several clamping rods 6 are arranged in a linear array along the bottom of each mounting plate 5 to contact and position the paper products from the side. A spacing adjustment assembly 9 is installed on each mounting plate 5 to adjust the horizontal spacing between adjacent clamping rods 6 to accommodate paper products of different widths and to perform variable-pitch alignment during conveying. The spacing adjustment assembly 9 includes a movable column 901, a pair of guide bars 902, and an adjusting component. The top of each clamping rod 6 is movably connected to the movable column 901 via a control groove 17, and the middle section of the movable column 901 movably passes through the corresponding drive groove 16. A pair of guide bars 902 are fixedly connected to one side wall of the plate 14 and movably pass through the rods of all the clamping rods 6 to guide the clamping rods 6 to maintain horizontal movement. The adjusting component is located on one side of the plate 14 to provide longitudinal driving force and control all the movable columns 901 and 902. 1. Moving along the extension direction of the drive groove 16, the adjusting component specifically includes an adjusting frame 903 and a pair of hydraulic cylinders 904. The adjusting frame 903 is movably set on the side of the plate 14 away from the guide bar 902. The section of the movable column 901 away from the clamping rod 6 is movably engaged with the inner side of the adjusting frame 903. The two ends of the adjusting frame 903 are longitudinally slidably engaged with the guide grooves preset on both sides of the plate 14. The pair of hydraulic cylinders 904 are fixedly connected to the top of the plate 14, and the ends of their telescopic rods are fixedly connected to the top of the adjusting frame 903. When it is necessary to adapt to paper products of different widths or to perform variable spacing alignment, the hydraulic cylinders 904 work to drive the adjusting frame 903 to rise and fall. The adjusting frame 903 drives all the movable columns 901 to move along the drive groove 16 through the guiding action of the inclined drive groove 16, thereby driving the clamping rod 6 to slide horizontally along the guide bar 902, realizing the expansion or reduction of the distance between adjacent clamping rods 6, and ensuring that the clamping force is evenly distributed.

[0026] The support rod 7 is a key component for bottom support protection in this equipment. Each clamping rod 6 has a rotatable support rod 7 at its bottom. After clamping and raising the paper product to remove it from the surface of the conveyor belt 3, the support rod 7 rotates downward to support the bottom of the paper product, forming a double anti-tipping protection of side clamping and bottom support. The bottom of the clamping rod 6 has a downward-opening receiving groove 18, and the bottom of the clamping rod 6 has a Y-shaped forked structure. The tail end of the support rod 7 is fixedly connected to a sleeve 19, which is rotatably connected inside the receiving groove 18. The main body of the support rod 7 has an L-shaped structure, and the tail end of the support rod 7 can be rotated and stored in the receiving groove 18. When not in operation, it does not protrude downward to avoid interfering with the operation of the conveyor belt 3. In order to prevent slippage, friction strips that increase friction are linearly arrayed on the bottom surface of the clamping rod 6 and the surface of the support rod 7.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the rotating assembly 10 is mounted on each mounting plate 5 and is used to drive the support rod 7 to rotate, thereby changing the extension state of the support rod 7 to support or release the paper product. The rotating assembly 10 is mounted on two support rods 15 and is used to control all sleeves 19 to rotate synchronously through a transmission structure, thereby synchronously changing the angular position of all support rods 7. The rotating assembly 10 specifically includes a rotating rod 1001, a first synchronous pulley 1002, a second set of synchronous pulleys 1003, a synchronous belt 1004, and a second servo motor 1005. The two ends of the rotating rod 1001 are respectively rotated and connected to the bottom ends of the two support rods 15. The cross-section of its middle end is polygonal, and the rotating rod 1001 moves through all the support rods 15. The sleeve 19 at the bottom of the clamping rod 6 is used to drive the sleeve 19 to rotate; the first synchronous pulley 1002 is fixedly connected to both ends of the rotating rod 1001; a set of second synchronous pulleys 1003 are movably connected to the internal cavity of the support rod 15 through a rotating shaft; each support rod 15 is provided with a synchronous belt 1004, and the synchronous belt 1004 is tensioned and sleeved on the outside of the first synchronous pulley 1002 and the second synchronous pulley 1003 to form a stable transmission structure; the second servo motor 1005 is fixedly connected to the outer wall of one of the support rods 15, and its output end extends into the inside of the support rod 15 and is connected to the rotating shaft of one of the second synchronous pulleys 1003 to provide the driving force for the rotation of the support rod 7.

[0028] Working process: First, the paper product is fed into the equipment from the upstream conveyor belt 3. The lifting inner frame 2 moves along the linear guide rail 11 of the fixed outer frame 1, aligning the clamping mechanism with the paper product. Then, the electric push cylinder 12 drives the support plate 20 to descend, positioning the clamping rods 6 on both sides of the paper product. Subsequently, the servo motor 804 of the control component 8 starts, driving the control rod 801 to rotate, causing the two mounting plates 5 to move closer together, clamping the paper product from the side with the clamping rods 6. After clamping, the electric push cylinder 12 retracts, causing the support plate 20 and the clamping mechanism to rise a certain distance, detaching the bottom of the paper product from the surface of the conveyor belt 3. At this time, the servo motor 1005 of the rotating component 10 starts, driving the rotating rod 10 01 rotates, causing all the support rods 7 to rotate downwards and extend synchronously, supporting the bottom of the paper product. If the orientation needs to be adjusted, the control motor 13 at the top of the support plate 20 drives the mounting frame 4 to rotate horizontally to the required angle for the next workstation. If the column spacing needs to be adjusted, the hydraulic cylinder 904 of the spacing adjustment component 9 changes the spacing of the clamping rods 6 to perform variable spacing alignment. After the adjustment is completed, the lifting inner frame 2 moves horizontally along the linear guide rail 11 to directly above the downstream conveyor belt 3. The electric push cylinder 12 descends to bring the paper product close to the downstream conveyor belt 3. The reverse operation of the rotation component 10 retracts the support rods 7, and the reverse operation of the control component 8 releases the clamping rods 6. The paper product can then fall smoothly onto the downstream conveyor belt 3, completing one cross-process transfer alignment operation.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

10. A method for conveying materials in the processing of packaging paper products, comprising a material conveying device for the processing of packaging paper products as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. After the paper product is fed into the lower part of the equipment by the upstream conveyor belt, the lifting inner frame moves along the linear guide rail of the fixed outer frame to align the clamping mechanism with the paper product. Then, the electric push cylinder drives the support plate to descend, so that the clamping rods on both sides are located on both sides of the paper product. S2. Once the servo motor of the control component starts, it drives the control lever to rotate, causing the two mounting plates to move closer to each other, so that the clamping rod clamps the paper product from the side. S3. When the paper product is clamped, the electric push cylinder retracts, driving the support plate and clamping mechanism to rise a certain distance, so that the bottom of the paper product is removed from the surface of the conveyor belt. At this time, the servo motor of the rotating component starts, drives the rotating rod to rotate, and drives all the support rods to rotate downward and extend synchronously, lifting the bottom of the paper product. S4. When the orientation needs to be adjusted, the control motor at the top of the support plate drives the mounting bracket to rotate horizontally to the angle required for the next station; if the column spacing needs to be adjusted, the hydraulic cylinder of the spacing adjustment component changes the spacing of the clamping rods to perform variable spacing alignment. S5. After adjustment, the lifting inner frame moves horizontally along the linear guide rail to directly above the downstream conveyor belt. The electric push cylinder descends to bring the paper product close to the downstream conveyor belt. The reverse operation of the rotating component retracts the support rod, and the reverse operation of the control component releases the clamping rod. The paper product can then fall smoothly onto the downstream conveyor belt, completing one cross-process transfer and alignment operation.
