Description

Technical Field

[0001] This invention belongs to the field of seedling tray processing technology, specifically a sheet production device for agricultural seedling trays. Background Technology

[0002] Agricultural seedling trays are plastic products specifically designed for plant cultivation, manufactured using machine compression molding technology. They possess breathable, water-retaining, and drainage properties, and are widely used in greenhouse, polytunnel, and indoor cultivation environments to improve crop yield and quality, ensure sufficient nutrition, and increase seedling survival rates. Before compression molding, the seedling trays require the corresponding sheets to be cut to meet the requirements of the subsequent compression molding process.

[0003] Before pressing and molding seedling trays, rolled sheets are often cut into block sheets and stacked to meet subsequent molding requirements. In existing technology, a cutting device is generally used to cut the sheets. This device usually consists of a cutting component and a conveyor belt. During use, the sheet is conveyed by the conveyor belt and cut to a fixed length by the cutting device. This cutting method requires the conveyor belt and the cutting component to work together to achieve the entire cutting process. When it is necessary to cut sheets of different specifications, it is necessary to adjust the single conveying interval of the conveyor belt and reposition the cutting component. The whole adjustment process is quite cumbersome.

[0004] After the sheet material is cut and trimmed, it is often necessary to stack the sheet material to facilitate subsequent pressing operations. In the existing technology, all the sheet material must be cut before stacking with a stacking device. That is, cutting and stacking are carried out separately. The whole process requires two different devices, which results in a long overall processing time and makes it impossible to stack the sheet material quickly after cutting, resulting in low overall processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet production apparatus for agricultural seedling trays to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sheet production device for agricultural seedling trays, comprising a frame, a conveyor belt installed inside the frame, a side guide rail fixedly installed on one side of the rear end of the frame, a fixed crossbar above the side guide rail, a lateral guide rod fixedly installed at the middle of the bottom end of the fixed crossbar, the fixed crossbar being movably engaged with the side guide rail via the lateral guide rod, the lateral guide rod shifting back and forth relative to the side guide rail, and main guide blocks movably engaged on both the front and rear sides inside the fixed crossbar, the main guide blocks shifting relative to the fixed crossbar, longitudinal guide rails fixedly installed on the front of each of the main guide blocks, and transverse guide rails fixedly installed on the front of each of the two longitudinal guide rails, the transverse guide rails and the longitudinal guide rails being perpendicular to each other, the fixed crossbar... An extension seat is fixedly installed on one side, and a transverse motor is fixedly installed on the inner side of the extension seat. A transverse threaded rod is movably connected inside the fixed crossbar. The outer side of the transverse threaded rod is threadedly sleeved with the middle of the main guide block. One end of the output shaft of the transverse motor is connected to one end of the transverse threaded rod. A cutting assembly is provided between the transverse guide rail and the longitudinal guide rail. There are two cutting assemblies, which correspond to the two transverse guide rails and the longitudinal guide rail respectively. A longitudinal adjusting rod is provided at the rear end of the cutting assembly. The front end of the longitudinal adjusting rod is connected to the two cutting assemblies. A top plate is provided at the top of the two longitudinal guide rails. The top plate is connected to the two longitudinal guide rails. An electric push rod is built into the side guide rail and is connected to one end of the lateral guide rod.

[0007] Before use, place the seedling tray sheet to be cut on top of the conveyor belt, and place the sheets to be stacked on the corresponding conveyor end of the conveyor belt. Adjust the cutting component to be above the conveyor belt to complete the preparation work before cutting the sheet.

[0008] As a further technical solution of the present invention, a longitudinal motor is fixedly installed at the middle of the bottom end of the top plate, and a longitudinal threaded rod is fixedly installed at the bottom end of the output shaft of the longitudinal motor, and the bottom end of the longitudinal threaded rod is movably connected to the middle of the top end of the fixed crossbar.

[0009] As a further technical solution of the present invention, a threaded groove is provided in the middle of the longitudinal adjusting rod, and the longitudinal threaded rod passes through the threaded groove and is threadedly connected to the middle of the longitudinal adjusting rod.

[0010] In the initial state, the longitudinal adjusting rod is at its lowest point, that is, the distance between the longitudinal adjusting rod and the fixed crossbar is at its minimum. When sheet cutting is required, the longitudinal threaded rod can be driven to rotate by turning on the longitudinal motor. At this time, the longitudinal adjusting rod can move up and down under the guidance of the cutting component. When the longitudinal adjusting rod moves upward, it can act on the cutting component to complete the linkage process.

[0011] As a further technical solution of the present invention, the thread directions on the front and rear sides of the outer side of the transverse threaded rod are opposite, and the thread direction of the corresponding main threaded groove inside the main threaded block is the same.

[0012] Before cutting the sheet, the device can be adjusted according to the required sheet specifications. This is achieved by turning on the horizontal motor to drive the horizontal threaded rod to rotate. At this time, the two main guide blocks will move back and forth under the guidance of the fixed crossbar. When the two main guide blocks are relatively close, they will synchronously drive the two cutting components to move closer to each other. At this time, the distance between the two cutting components will decrease, and the width of the cut sheet will decrease accordingly.

[0013] When the two main guide blocks move away from each other, the distance between the two cutting components increases, which means the width of the cut sheet increases, thus completing the process of adjusting the sheet cutting specifications.

[0014] As a further technical solution of the present invention, the cutting assembly includes a longitudinal guide block, one end of which is movably connected to a longitudinal adjusting rod, and the longitudinal guide block is movably engaged with a longitudinal guide rail. The longitudinal guide block moves up and down relative to the longitudinal guide rail, and the rear end of the longitudinal guide block is connected to the longitudinal adjusting rod. A first fixing seat is fixedly connected to the end of the longitudinal guide block away from the longitudinal adjusting rod.

[0015] As a further technical solution of the present invention, the end of the first fixed seat away from the longitudinal guide block is movably connected to a connecting rod via a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft. The bottom end of the second fixed seat is fixedly connected to a transverse guide block, and the transverse guide block is movably engaged with the transverse guide rail. The transverse guide block moves left and right relative to the transverse guide rail.

[0016] As a further technical solution of the present invention, each of the transverse guide blocks is fixedly connected to a material separating blade at its bottom end. Each of the material separating blades has a cutting notch at its bottom end and a slot in its middle. Each slot has a locking block that is movably engaged inside it, and the locking block moves up and down relative to the slot.

[0017] After the cutting specifications are adjusted, when the sheet needs to be cut, the longitudinal adjusting rod is initially at its lowest point, and the cutting blade is also located on one side of the sheet. When the sheet needs to be cut, the longitudinal adjusting rod can be raised, and the longitudinal guide block will rise accordingly, causing the connecting rod to deflect. The transverse guide block will then be pulled to one side, which will cause the cutting blade to move to the other side of the sheet. The cutting process of the sheet is completed by the pulling of the cutting blade.

[0018] By setting up two cutting components and cooperating with the transverse threaded rod, the cutting specifications can be quickly adjusted. At the same time, the linkage between the longitudinal adjusting rod and the cutting components is coordinated. By utilizing the law of the sum of the interior angles of a triangle, the automatic displacement of the dividing knife is achieved when the longitudinal adjusting rod rises. The entire process only requires controlling the displacement of the longitudinal adjusting rod to achieve a rapid pulling cutting process. Moreover, it can achieve the same result without adjusting the conveyor interval when dealing with sheets of different specifications, thus optimizing the adjustment process and enabling a rapid cutting process.

[0019] As a further technical solution of the present invention, an electromagnet is fixedly installed at the top of the card block, and a trimming knife located on one side of the material separating knife is fixedly connected to the bottom of the card block. When the bottom of the card block contacts the bottom of the card slot cavity, the bottom of the trimming knife protrudes from the bottom of the material separating knife.

[0020] After the sheet cutting is completed, the longitudinal adjustment rod is at its highest point, and the cutting blade is located on one side of the sheet. At this point, the power to the clamping block can be turned off. The clamping block will then fall freely along the clamping groove, causing the trimming blade to descend. The lowest point of the trimming blade will be lower than the lowest point of the cutting blade. If the longitudinal adjustment rod is continued to descend, the cutting blade will automatically reset and move back to its initial position, i.e., perform a return stroke. At this point, the trimming blade can contact the side of the sheet. Combined with the return stroke of the cutting blade, automatic trimming can be achieved.

[0021] By utilizing the vertical displacement of the longitudinal adjustment rod during the cutting process, the sheet material is automatically cut when the longitudinal adjustment rod moves upward, and when the longitudinal adjustment rod moves downward (i.e., reset), the trimming knife moves downward to replace the separating knife. The return motion of the separating knife can achieve automatic trimming after cutting. The whole process is completed quickly. The device achieves self-trimming by resetting, eliminating the need for the traditional device to trim all edges after cutting. This simplifies the processing steps and improves the overall processing efficiency.

[0022] As a further technical solution of the present invention, an extension frame is fixedly installed at the middle of the longitudinal adjusting rod near the cutting assembly, an extension rod is fixedly connected to the bottom end of the extension frame, and a vacuum suction cup is fixedly connected to the bottom end of the extension rod.

[0023] During the sheet cutting process, in the initial state, the longitudinal adjustment rod is at its lowest point, and the vacuum suction cup is directly above and in contact with the sheet. Before cutting begins, the vacuum suction cup can be activated to adsorb the sheet. As cutting proceeds, the cutting blade can cut the sheet, and the longitudinal adjustment rod moves upward, which in turn moves the vacuum suction cup upward, thus simultaneously moving the sheet upward to complete the sheet suction process and providing upward pulling force to assist in the sheet cutting.

[0024] Furthermore, during the cutting process, the electric push rod control device located inside the side guide rail can be activated to move towards the conveyor end of the conveyor belt, which will also move the sheet towards the conveyor end of the conveyor belt. After the sheet is cut, the sheet will be positioned directly above the stack.

[0025] At this point, the cutting component can be reset, completing the automatic trimming process of the sheet. Simultaneously, the longitudinal adjustment rod automatically descends. When the longitudinal adjustment rod descends to its lowest point, indicating that the device has completed its reset, the vacuum suction cup can be turned off to automatically release the cut sheet, thus completing the automatic stacking process.

[0026] By utilizing the sheet cutting and automatic trimming process, the sheet is automatically picked up and moved during cutting, and automatically released and stacked during trimming. The entire stacking process can be carried out simultaneously with the sheet cutting, which significantly shortens the processing time, effectively avoids the problem of additional sheet stacking required by traditional devices, improves the automation level of the device, and increases the overall processing efficiency.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention sets up two cutting components and uses a transverse threaded rod to quickly adjust the cutting specifications. At the same time, it uses the linkage between the longitudinal adjusting rod and the cutting components and utilizes the law of the sum of the interior angles of a triangle to achieve automatic displacement of the dividing knife when the longitudinal adjusting rod rises. The entire process only requires controlling the displacement of the longitudinal adjusting rod to achieve a fast pulling cutting process. Moreover, it can achieve the cutting process without adjusting the conveying interval when dealing with sheets of different specifications, thus optimizing the adjustment process and enabling a fast cutting process.

[0029] 2. This invention utilizes the cutting and automatic trimming process of sheet materials. Specifically, the sheet material is automatically picked up and displaced during cutting, and automatically released and stacked during trimming. The entire stacking process can be carried out simultaneously with the sheet cutting, significantly shortening the processing time, effectively avoiding the problem of additional sheet stacking required by traditional devices, improving the automation level of the device, and increasing the overall processing efficiency.

[0030] 3. This invention utilizes the vertical displacement of the longitudinal adjustment rod during the cutting process. When the longitudinal adjustment rod moves upward, the sheet material is automatically cut. When the longitudinal adjustment rod moves downward (i.e., resets), the trimming knife moves downward to replace the separating knife. The return motion of the separating knife enables automatic trimming after cutting. The entire process is completed quickly. The device's reset mechanism enables self-trimming, eliminating the need for traditional devices to trim edges uniformly after cutting. This simplifies the processing steps and improves overall processing efficiency. Attached Figure Description

[0041] 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.

[0042] like Figures 1 to 9As shown in the embodiment of the present invention, an agricultural seedling tray sheet production device includes a frame 1. A conveyor belt 2 is installed inside the frame 1. A side guide rail 3 is fixedly installed on one side of the rear end of the frame 1. A fixed crossbar 6 is provided above the side guide rail 3. A lateral guide rod 19 is fixedly installed in the middle of the bottom end of the fixed crossbar 6. The fixed crossbar 6 is movably engaged with the side guide rail 3 through the lateral guide rod 19. The lateral guide rod 19 moves back and forth relative to the side guide rail 3. A main guide block 7 is movably engaged on both the front and rear sides inside the fixed crossbar 6. The main guide block 7 moves relative to the fixed crossbar 6. A longitudinal guide rail 5 is fixedly installed on the front of each of the two longitudinal guide rails 5. A transverse guide rail 4 is fixedly installed on the front of each of the two longitudinal guide rails 5. The transverse guide rail 4 and the longitudinal guide rail 5 are perpendicular to each other. An extension rod is fixedly installed on one side of the fixed crossbar 6. A transverse motor 9 is fixedly installed on the inner side of the seat 8 and the extension seat 8. A transverse threaded rod 10 is movably connected inside the fixed crossbar 6. The outer side of the transverse threaded rod 10 is threadedly connected to the middle of the main guide block 7. One end of the output shaft of the transverse motor 9 is connected to one end of the transverse threaded rod 10. A cutting assembly 14 is provided between the transverse guide rail 4 and the longitudinal guide rail 5. There are two cutting assemblies 14, which correspond to the two transverse guide rails 4 and the longitudinal guide rail 5 respectively. A longitudinal adjusting rod 15 is provided at the rear end of the cutting assembly 14. The front end of the longitudinal adjusting rod 15 is connected to the two cutting assemblies 14. A top plate 11 is provided at the top of the two longitudinal guide rails 5. The top plate 11 is connected to the two longitudinal guide rails 5. An electric push rod is built into the side guide rail 3 and is connected to one end of the side guide rod 19.

[0043] Before use, the seedling tray sheet to be cut should be placed above the conveyor belt 2, and the sheets to be stacked should be placed at the conveyor end of the conveyor belt 2. The cutting component 14 should be adjusted above the conveyor belt 2 to complete the preparation work before cutting the sheet.

[0044] like Figure 2 and Figure 3 as well as Figure 6 As shown, a longitudinal motor 12 is fixedly installed at the middle of the bottom end of the top plate 11. A longitudinal threaded rod 13 is fixedly installed at the bottom end of the output shaft of the longitudinal motor 12. The bottom end of the longitudinal threaded rod 13 is movably connected to the middle of the top end of the fixed crossbar 6. A threaded groove is opened in the middle of the longitudinal adjusting rod 15. The longitudinal threaded rod 13 passes through the threaded groove and is threadedly connected to the middle of the longitudinal adjusting rod 15.

[0045] In the initial state, the longitudinal adjusting rod 15 is located at the lowest point, that is, the distance between the longitudinal adjusting rod 15 and the fixed crossbar 6 is at its minimum. When sheet cutting is required, the longitudinal threaded rod 13 can be driven to rotate by turning on the longitudinal motor 12. At this time, the longitudinal adjusting rod 15 can move up and down under the guidance of the cutting assembly 14. When the longitudinal adjusting rod 15 moves upward, it can act on the cutting assembly 14 to complete the linkage process.

[0046] like Figure 2 and Figure 4 as well as Figure 5 As shown, the thread directions on the front and rear sides of the outer side of the transverse threaded rod 10 are opposite, and the thread directions of the corresponding main guide block 7 are the same.

[0047] Before cutting the sheet, the device can be adjusted according to the required sheet specifications. That is, by turning on the horizontal motor 9, the horizontal threaded rod 10 can be driven to rotate. At this time, the two main guide blocks 7 can move back and forth under the guidance of the fixed crossbar 6. When the two main guide blocks 7 are relatively close, they can synchronously drive the two cutting components 14 to be relatively close. At this time, the distance between the two cutting components 14 decreases, and the width of the cut sheet decreases accordingly.

[0048] When the two main guide blocks 7 are relatively far apart, the distance between the two cutting components 14 increases accordingly, that is, the width of the cut sheet increases accordingly, thus completing the process of adjusting the sheet cutting specifications.

[0049] like Figure 1 and Figure 7 and Figure 8 as well as Figure 9 As shown, the cutting assembly 14 includes a longitudinal guide block 141, which is movably connected to one end of a longitudinal adjusting rod 15. The longitudinal guide block 141 is also movably engaged with a longitudinal guide rail 5, allowing it to move vertically relative to the longitudinal guide rail 5. The rear end of the longitudinal guide block 141 is connected to the longitudinal adjusting rod 15. A first fixing seat 142 is fixedly connected to the end of the longitudinal guide block 141 away from the longitudinal adjusting rod 15. A connecting rod 144 is movably connected to the end of the first fixing seat 142 away from the longitudinal guide block 141 via a rotating shaft. A second fixing seat 143 is movably connected to the end of the connecting rod 144 away from the first fixing seat 142 via a rotating shaft. Each of the two cutting components 14 is fixedly connected to a horizontal guide block 145 at its bottom end. The horizontal guide block 145 is movably engaged with the horizontal guide rail 4. The horizontal guide block 145 moves left and right relative to the horizontal guide rail 4. Each of the horizontal guide blocks 145 is fixedly connected to a material separating blade 146 at its bottom end. Each material separating blade 146 has a cutting notch at its bottom end and a slot 147 in the middle of its middle. Each slot 147 has a locking block 148 movably engaged inside it. The locking block 148 moves up and down relative to the slot 147. The longitudinal guide block 141 can move up and down with the longitudinal adjusting rod 15. At the same time, the two longitudinal guide blocks 141 can move back and forth relative to the longitudinal adjusting rod 15 to adjust the distance between the two cutting components 14.

[0050] Example 1: After the cutting specifications are adjusted, when the sheet needs to be cut, the longitudinal adjusting rod 15 is initially at its lowest point, and the dividing blade 146 is also located on one side of the sheet. When the sheet needs to be cut, the longitudinal adjusting rod 15 can be raised, and the longitudinal guide block 141 will rise accordingly, causing the connecting rod 144 to deflect. At this time, the transverse guide block 145 will be pulled to one side, which will drive the dividing blade 146 to move to the other side of the sheet, thereby completing the cutting process of the sheet by pulling the dividing blade 146.

[0051] By setting two cutting components 14 and cooperating with the transverse threaded rod 10, the cutting specifications can be quickly adjusted. At the same time, the linkage between the longitudinal adjusting rod 15 and the cutting components 14 is coordinated. By utilizing the law of the sum of the interior angles of a triangle, the automatic displacement of the dividing blade 146 is achieved when the longitudinal adjusting rod 15 rises. The entire process only requires controlling the displacement of the longitudinal adjusting rod 15 to achieve a rapid pulling cutting process. Moreover, it can achieve the desired cutting speed without adjusting the conveying interval when dealing with sheets of different specifications, thus optimizing the adjustment process and enabling a rapid cutting process.

[0052] like Figure 8 and Figure 9 As shown, an electromagnet 149 is fixedly installed on the top of the locking block 148, and a trimming knife 1410 located on one side of the distributing knife 146 is fixedly connected to the bottom of the locking block 148. When the bottom of the locking block 148 contacts the bottom of the inner cavity of the locking groove 147, the bottom of the trimming knife 1410 protrudes from the bottom of the distributing knife 146.

[0053] After the sheet cutting is completed, the longitudinal adjustment rod 15 is at its highest point, and the separating blade 146 is located on one side of the sheet. At this time, the power of the clamping block 148 can be turned off. The clamping block 148 falls freely along the clamping groove 147, and drives the trimming blade 1410 to descend. The lowest point of the trimming blade 1410 is lower than the lowest point of the separating blade 146. If the longitudinal adjustment rod 15 continues to descend, the separating blade 146 will automatically reset and move back to its initial position, i.e., perform the return stroke. At this time, the trimming blade 1410 can contact the side of the sheet. With the return stroke of the separating blade 146, automatic trimming operation can be achieved.

[0054] By utilizing the vertical displacement of the longitudinal adjustment rod 15 during the cutting process, the cutting process of the sheet material is automatically realized when the longitudinal adjustment rod 15 moves upward, and when the longitudinal adjustment rod 15 moves downward (i.e., reset), the trimming knife 1410 moves downward to replace the separating knife 146. The return motion of the separating knife 146 can realize automatic trimming after cutting. The whole process is completed quickly. That is, the self-trimming is realized by the reset of the device, eliminating the need for the traditional device to trim the edges uniformly after cutting, simplifying the processing steps, and thus improving the overall processing efficiency.

[0055] like Figure 1 and Figure 2 as well as Figure 3 and Figure 7 As shown, an extension frame 16 is fixedly installed at the middle of the longitudinal adjustment rod 15 near the cutting assembly 14. An extension rod 17 is fixedly connected to the bottom end of the extension frame 16, and a vacuum suction cup 18 is fixedly connected to the bottom end of the extension rod 17.

[0056] Example 2: During the sheet cutting process, in the initial state, since the longitudinal adjustment rod 15 is at its lowest point, the vacuum suction cup 18 is directly above and in contact with the sheet. Before cutting begins, the vacuum suction cup 18 can be turned on to adsorb the sheet. As cutting proceeds, the cutting blade 146 can cut the sheet. At the same time, the longitudinal adjustment rod 15 moves upward, which can synchronously drive the vacuum suction cup 18 to move upward. At this time, the sheet can be moved upward simultaneously to complete the sheet suction process, while providing an upward pulling force to assist the sheet cutting.

[0057] Furthermore, during the cutting process, the electric push rod control device located inside the side guide rail 3 can be activated to move towards the conveyor end of the conveyor belt 2, which will also move the sheet towards the conveyor end of the conveyor belt 2. After the sheet is cut, the sheet will be positioned directly above the stack.

[0058] At this point, the cutting component 14 can be reset, which completes the automatic trimming process of the sheet. At the same time, the longitudinal adjustment rod 15 automatically descends. When the longitudinal adjustment rod 15 descends to the lowest point, the device has completed its reset. Then, the vacuum suction cup 18 can be turned off to automatically release the cut sheet, thus completing the automatic stacking process.

[0059] By utilizing the sheet cutting and automatic trimming process, the sheet is automatically picked up and moved during cutting, and automatically released and stacked during trimming. The entire stacking process can be carried out simultaneously with the sheet cutting, which significantly shortens the processing time, effectively avoids the problem of additional sheet stacking required by traditional devices, improves the automation level of the device, and increases the overall processing efficiency.

[0060] Working principle and usage process:

[0061] Before use, the seedling tray sheet to be cut should be placed above the conveyor belt 2, and the sheets to be stacked should be placed at the conveyor end of the conveyor belt 2. The cutting component 14 should be adjusted to be above the conveyor belt 2 to complete the preparation work before cutting the sheet.

[0062] In the initial state, the longitudinal adjusting rod 15 is located at the lowest point, that is, the distance between the longitudinal adjusting rod 15 and the fixed crossbar 6 is the minimum value. When sheet cutting is required, the longitudinal threaded rod 13 can be driven to rotate by turning on the longitudinal motor 12. At this time, the longitudinal adjusting rod 15 can move up and down under the guidance of the cutting assembly 14. When the longitudinal adjusting rod 15 moves upward, it can act on the cutting assembly 14 to complete the linkage process.

[0063] Before cutting the sheet, the device can be adjusted according to the required sheet specifications. That is, by turning on the horizontal motor 9, the horizontal threaded rod 10 can be driven to rotate. At this time, the two main guide blocks 7 can move back and forth under the guidance of the fixed crossbar 6. When the two main guide blocks 7 are relatively close, they can synchronously drive the two cutting components 14 to be relatively close. At this time, the distance between the two cutting components 14 is reduced, and the width of the cut sheet is reduced accordingly.

[0064] When the two main guide blocks 7 are relatively far apart, the distance between the two cutting components 14 increases accordingly, that is, the width of the cut sheet increases accordingly, thus completing the process of adjusting the sheet cutting specifications.

[0065] After the cutting specifications are adjusted, when the sheet needs to be cut, the longitudinal adjusting rod 15 is in the lowest position in the initial state. At this time, the dividing blade 146 is also located on one side of the sheet. When the sheet needs to be cut, the longitudinal adjusting rod 15 can be raised. At this time, the longitudinal guide block 141 rises accordingly and drives the connecting rod 144 to deflect. At this time, the transverse guide block 145 is pulled to one side, which can drive the dividing blade 146 to move to the other side of the sheet. Thus, the cutting process of the sheet is completed by the pulling of the dividing blade 146.

[0066] After the sheet cutting is completed, the longitudinal adjustment rod 15 is at its highest point, and the dividing blade 146 is located on one side of the sheet. At this time, the power of the clamping block 148 can be turned off. The clamping block 148 falls freely along the clamping groove 147 and drives the trimming blade 1410 to descend. The lowest point of the trimming blade 1410 is lower than the lowest point of the dividing blade 146. If the longitudinal adjustment rod 15 is controlled to descend, the dividing blade 146 will automatically reset and move back to its initial position, i.e., perform the return stroke. At this time, the trimming blade 1410 can contact the side of the sheet. With the return stroke of the dividing blade 146, automatic trimming operation can be achieved.

[0067] During the sheet cutting process, in the initial state, since the longitudinal adjustment rod 15 is at its lowest point, the vacuum suction cup 18 is directly above and in contact with the sheet. Before cutting begins, the vacuum suction cup 18 can be turned on to adsorb the sheet. As cutting proceeds, the cutting blade 146 can cut the sheet. At the same time, the longitudinal adjustment rod 15 moves upward, which can simultaneously drive the vacuum suction cup 18 to move upward. This can simultaneously drive the sheet to move upward, completing the sheet suction process, and providing upward pulling force to assist in the sheet cutting.

[0068] Furthermore, during the cutting process, the electric push rod control device located inside the side guide rail 3 can be activated to move towards the conveyor end of the conveyor belt 2, which will also move the sheet towards the conveyor end of the conveyor belt 2. After the sheet is cut, the sheet will be positioned directly above the stack.

[0069] At this point, the cutting component 14 can be reset, which completes the automatic trimming process of the sheet. At the same time, the longitudinal adjustment rod 15 automatically descends. When the longitudinal adjustment rod 15 descends to the lowest point, the device has completed its reset. Then, the vacuum suction cup 18 can be turned off to automatically release the cut sheet, thus completing the automatic stacking process.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
