Description

Technical Field

[0001] This utility model relates to the technical field of product packaging and sorting equipment, specifically a sheet material handling equipment. Background Technology

[0002] Existing sheet material handling equipment uses a linear conveyor system, followed by manual counting, to group a certain number of sheet materials into packages, stack them, and place them into boxes. However, the existing manual counting method is difficult to count and handle sheet materials quickly, and cannot achieve automated sheet material production. Utility Model Content

[0003] The purpose of this utility model is to provide a sheet feeding device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A sheet feeding device, comprising:

[0006] A first mounting frame is provided with a first conveying device, with the conveying direction of the first conveying device as the first direction. A card issuing assembly is provided on the first mounting frame, and the card issuing assembly is provided with a card issuing station. The output end of the first conveying device is connected to the card issuing station.

[0007] The second mounting frame has a transmission channel with an opening at the top, and a second conveying device is provided in the transmission channel. The first mounting frame is located on one side of the second mounting frame, and the output end of the card issuing station is located above the transmission channel.

[0008] This technical solution has at least the following beneficial effects:

[0009] First, the card-issuing component ensures the stability of the preset output quantity of sheet material. When the preset quantity of sheet material is output, the card-issuing action can be stopped, avoiding problems such as missed counting and double counting caused by human visual fatigue. Then, through the cooperation of the first and second conveyor devices, the precise dropping and positioning of the sheet material is achieved. Workers only need to place or arrange the sheet material on the first conveyor belt at the rear. Subsequent actions can be completed automatically by the cooperation of various devices without human intervention, eliminating the risk of material damage caused by manual operation.

[0010] This solution enables fully automated operation of the initial transfer, counting, and quantitative stacking of the product sheet material, thereby improving overall production efficiency.

[0011] As a further improvement to the above technical solution, the transmission direction of the second transmission device is taken as the second direction, and the transmission channel extends along the second direction, which is horizontally perpendicular to the first direction.

[0012] By adopting the above technical solution, after the card-issuing component of the first conveying device counts the sheet material piece by piece, the sheet material is automatically and linearly arranged in the first direction in the conveying channel by the combined action of gravity throwing and the horizontal and vertical conveying direction of the second conveying device, forming a sheet material group that can be directly packaged. When the number of sheet materials in the sheet material group reaches the preset number, the second conveying device is directly started to transport the entire group of sheet materials to the packaging station in one go along the second direction. Compared with the traditional solution of manually stacking and aligning sheet materials one by one, a lot of arrangement and combination time is saved.

[0013] As a further improvement to the above technical solution, the first mounting bracket is provided with a first guide plate at the output end of the card issuing assembly. The end of the first guide plate near the card issuing assembly is located above the output end of the card issuing station. The end of the first guide plate away from the card issuing assembly extends downward and toward the transmission channel. The downward end of the first guide plate extends horizontally and is parallel to the extension direction of the transmission channel.

[0014] By adopting the above technical solution, the first guide plate itself forms a continuous slide structure, so that the sheet material is thrown out from the card issuing station and slides down the guide plate at a uniform speed, avoiding the sheet material from colliding with the edge of the channel or being misaligned due to inertial deviation. Secondly, by setting the orientation of the bottom of the first guide plate, the bottom of the sheet material can form a horizontal and parallel posture with the extension direction of the transmission channel when it slides close to the edge of the first guide plate, thereby stably stacking in the transmission channel.

[0015] As a further improvement to the above technical solution, a baffle is provided on the side wall of the transmission channel away from the first mounting bracket. The baffle is provided with side plates extending toward the first mounting bracket on both sides along the second direction. A limiting space is formed between the two side plates and the baffle. The limiting space is located below the downward end of the first guide plate.

[0016] The limiting space formed by the baffle and the two side plates is located directly below the end of the first guide plate. When the sheet falls, it is blocked by the vertical resistance of the baffle and constrained by the bidirectional resistance of the side plates, which restricts the movement of the sheet in the first and second directions and further improves the stability of the sheet in the transmission channel.

[0017] As a further improvement to the above technical solution, the second mounting bracket is provided with a driving component on one side of the baffle. The driving component has a driving end, and a pressure plate is connected to the driving end. The driving end can drive the pressure plate to move in and out of the transmission channel along a direction parallel to the second direction.

[0018] Using a movable pressure plate, before the sheet falls, the drive end moves the pressure plate towards the direction of entering the transmission channel, thereby compressing the limiting space. This ensures that the sheet falls stably into the limiting space along the gap between the baffle and the pressure plate and remains upright, further improving the stability of the sheet falling. Then, during the falling process, the drive end moves the pressure plate backward until it exits the transmission channel, expanding the limiting space and providing sufficient space for the sheet falling. During the continuous falling process, the gaps between the sheets in the same limiting space are large, and the whole is loose. At this time, the pressure plate that has moved out of the transmission channel re-enters the transmission channel and is flush with the side wall of the transmission channel, pressing the sheet group so that the width of the sheet group is consistent with the width of the transmission channel. Thus, when the second conveying device moves the sheet group, the transmission channel limits the sheet group in the first direction, allowing the sheet group to be transmitted smoothly.

[0019] As a further improvement to the above technical solution, a base plate is also provided on the drive end, and the base plate is located at the bottom of the limiting space. After the sheet material falls into the limiting space, it will fall onto the base plate. At this time, the drive end synchronously drives the base plate, causing the sheet material on the base plate to move, so that the sheet material that has fallen into the limiting space can move away from the baffle, thereby forming a sufficient gap on the side to facilitate the next sheet material to fall in, ensuring smooth material falling. At the same time, it can also ensure that the next sheet material falls on the side, enhancing the regularity of the sheet material arrangement, and also reducing collisions between sheet materials, reducing the occurrence of scratches or damage.

[0020] As a further improvement to the above technical solution, the second conveying device includes a plurality of drive rods that can move along a first direction within the transmission channel. The two ends of the drive rods are respectively installed on both sides of the transmission channel along the first direction, and the drive rods can move to the side of the limiting space opposite to the second direction.

[0021] Through the above technical solution, after a preset number of sheets fall into the confined space, the drive rod extending along the first direction moves and simultaneously abuts against and pushes multiple sheets, thereby pushing the group of sheets along the second mounting frame to the next process. This pushing method ensures that the entire sheet group moves as a whole. This avoids misalignment or scattering of the sheets within the sheet group during the pushing process, maintaining the regularity of the sheet arrangement within the confined space.

[0022] As a further improvement to the above technical solution, a second guide plate is provided on the side of the baffle near the first mounting bracket. The second guide plate includes an arc-shaped segment and a guide segment connected to each other. One end of the arc-shaped segment is connected to the baffle, and the other end extends downward and is connected to the guide segment. The side of the outer arc surface of the arc-shaped segment away from the baffle faces the downward end of the first guide plate. The end of the guide segment away from the arc-shaped segment extends downward and faces the edge of the limiting space away from the first mounting bracket.

[0023] Because the sheet material still has a certain moving speed after being transported by the first conveying device, if the first guide plate is directly aligned with the conveying channel and the sheet material is dropped, it may directly impact the baffle or fall on top of the sheet material that has already been stacked in the limiting space due to the inertia of the sheet material, making it impossible to complete the stacking of the predetermined number of sheet materials normally. However, by setting the second guide plate, a sliding path is formed that slides away from the pressure plate, so that the sheet material can stably fall towards the edge of the limiting space.

[0024] As a further improvement to the above technical solution, the guide section is elastically connected to the arc-shaped section, and the end of the guide section away from the arc-shaped section is a free end. In order to speed up the feeding speed and improve the speed of the entire production process, a larger conveying speed is set on the first conveyor belt and the card issuing assembly, so that the sheet material has a larger initial velocity. Through the elastic connection between the guide section and the arc-shaped section, after the sheet material comes into contact with the guide section, it will drive the guide section to deform towards the baffle, thereby changing the guiding path scheme on the guide section, making the sheet material move closer to the edge of the limiting space. At the same time, compared with the rigid guide section, the elastically deformable guide section reduces the rigid collision with the sheet material, and can buffer the sheet material during the contact process, reduce the kinetic energy of the sheet material, thereby reducing the collision deformation of the sheet material after hitting the bottom, thus affecting the situation where the next sheet material collides with the already deformed sheet material after falling and deviates from the original falling path.

[0025] As a further improvement to the above technical solution, the second mounting frame is connected to a packaging mechanism at the output end of the second conveying device. A packaging channel is formed within the packaging mechanism and communicates with the conveying channel. By setting a packaging mechanism at the conveying end of the second mounting frame, the stacked sheets are directly packaged, further improving the automation level of the equipment.

[0040] The sheet material processing equipment provided in this application is suitable for sheet products such as square packaging bags. In particular, in this embodiment, the sheet product is a sheet-shaped facial mask packaging bag.

[0041] Reference Figure 1 , Figure 2 and Figure 3 This application provides a sheet material processing device, which includes a first mounting frame 1, a second mounting frame 2, and a packaging mechanism 3. The first mounting frame 1 is provided with a first conveying device 11, with the conveying direction of the first conveying device 11 as the first direction. The first mounting frame 1 is provided with a card issuing component 12 for distributing sheet materials. The card issuing component 12 is provided with a card issuing station. The output end of the first conveying device 11 is connected to the card issuing station. In this embodiment, the card issuing component 12 can be a card issuing machine that can issue cards to mask packaging bags. This application does not specifically limit this.

[0042] The second mounting frame 2 has an opening at the top and a transmission channel 22 extending in a direction parallel to the horizontal plane. The direction of extension of the transmission channel 22 is the second direction. The first direction and the second direction are perpendicular to each other in the horizontal plane. A second conveying device 21 is provided in the transmission channel 22. The first mounting frame 1 is located on one side of the second mounting frame 2 and the two are horizontally perpendicular to each other. The output end of the card issuing station is located above the transmission channel 22.

[0043] The packaging mechanism 3 is located at the end of the second mounting frame 2 along the second direction. The packaging mechanism 3 forms a packaging channel, which is connected to the transmission channel 22 and the sheet material is transmitted to the packaging channel through the second conveying device 21. The packaging mechanism 3 can be a bag packaging machine. This application embodiment does not specifically limit the specific model of the packaging machine.

[0044] As described above, the card-issuing component 12 ensures the stability of the preset output quantity of sheet materials. It stops issuing cards when the preset quantity of sheet materials is output, avoiding problems such as missed or duplicate counting caused by human visual fatigue. Furthermore, through the cooperation of the first conveyor device 11 and the second conveyor device 21, precise dropping and positioning of the sheet materials is achieved. Workers only need to place or arrange the sheet materials on the first conveyor belt behind them; subsequent actions can be completed automatically by the various devices without human intervention, eliminating the risk of material loss due to manual operation. This solution enables fully automated operation of the initial transmission, counting, and quantitative stacking of the sheet materials, improving overall production efficiency.

[0045] In an L-shaped structural layout formed by the first mounting frame 1 and the second mounting frame 2 perpendicular to each other, after the card-issuing component 12 on the first mounting frame 1 feeds the sheet material from the first conveyor belt, the sheet material changes from a horizontal posture on the first conveyor belt to a vertical posture and falls. When the sheet material falls into the transmission channel 22 one by one, the sheet material in the vertical posture can automatically and linearly arrange itself in the first direction in the transmission channel 22 to form a sheet material group that can be directly packaged. When the number of sheet materials in the sheet material group reaches the preset number, the second conveying device 21 is directly started to transport the entire group of sheet materials to the packaging station in one go along the second direction. Compared with the traditional solution of manually stacking and aligning the sheet materials one by one, a lot of arrangement and combination time and manpower and material resources are saved.

[0046] As a further preferred embodiment, a second mounting frame 2 is equipped with multiple sets of first mounting frames 1. These sets of first mounting frames 1 are respectively installed on any side of the second mounting frame 2. Each set includes at least one first mounting frame 1. An operating gap is provided between adjacent sets of first mounting frames 1 for workers to adjust and place sheet material. The length of this operating gap in the second direction is an integer multiple of the required length of the connecting portion of the first mounting frame 1 on the second mounting frame 2 in the second direction. This multiple is the number of first mounting frames 1 in a single set. Through this operating gap, workers can adjust the sheet material feeding on the first conveying device 11 of each set of first mounting frames 1, aligning the sheet material on the first conveying device 11 to facilitate the smooth transfer of the sheet material to the second mounting frame 2 by the card issuing assembly 12.

[0047] The first conveying device 11 can be any linear transport device. This application does not make any specific limitation. It is only necessary to enable the movement of the sheet material on the first mounting frame 1. In this application, a belt conveyor is used as an example. The output end of the belt conveyor is connected to the card issuing component 12.

[0048] Specifically, refer to Figure 4 and Figure 5The second conveying device 21 includes a plurality of drive rods 23 that can move along a first direction within the conveying channel 22. The plurality of drive rods 23 are arranged at intervals along a second direction. The two ends of each drive rod 23 are respectively installed on both sides of the conveying channel 22 along the first direction, that is, each drive rod 23 extends along the first direction. Specifically, the second conveying device 21 includes a chain and sprocket assembly and drive rods 23. The chain and sprocket assembly is installed inside the second mounting frame 2 and transmits along the second direction. Two chains are provided and are respectively installed on both sides of the second mounting frame 2 along the first direction. The second mounting frame 2 is provided with clearance channels 24 extending along the second direction on both sides of the conveying channel 22 along the first direction. The two ends of the drive rods 23 pass through the clearance channels 24 on both sides and are connected to the chains inside the second mounting frame 2. The two ends of the drive rods 23 are respectively inserted into the holes of the chains on both sides.

[0049] As described above, after the sheet material falls into the transmission channel 22, the drive rod 23 extending along the first direction moves and simultaneously abuts against and pushes multiple sheet materials, thereby pushing the grouped sheet materials along the second mounting frame 2 to the next process. This pushing method ensures that the entire sheet material group moves as a whole. This avoids misalignment or scattering of the sheet materials inside the sheet material group during the pushing process, maintaining the regularity of the sheet materials' arrangement within the limiting space 52.

[0050] Reference Figure 3 The first mounting bracket 1 has a first guide plate 4 at the output end of the card-issuing assembly 12. The end of the first guide plate 4 near the card-issuing assembly 12 is located above the card-issuing station. The end of the first guide plate 4 near the card-issuing assembly 12 has a first guide plate 41. The first guide plate 41 is inclined upward in the direction away from the card-issuing assembly 12, thereby forming a guide for the sheet material to abut against the first guide plate 4. The cross-sectional shape of the first guide plate 4 on the vertical plane perpendicular to the second direction is L-shaped. The end of the first guide plate 4 away from the card-issuing assembly 12 extends downward and faces directly towards the output end of the card-issuing assembly 12. The first guide plate 4 extends horizontally parallel to the direction of the transmission channel 22 at its lower end. The first guide plate 4 forms a continuous slide structure, which allows the sheet material to slide down at a uniform speed along the guide plate trajectory after being thrown from the card issuing station. This avoids the sheet material from colliding with the edge of the channel or being misaligned due to inertial deviation. Furthermore, by setting the orientation of the bottom of the first guide plate 4, the bottom of the sheet material can form a horizontal and parallel posture with the extension direction of the transmission channel 22 when it slides close to the edge of the first guide plate 4, thereby stably stacking within the transmission channel 22.

[0051] Reference Figure 4 , Figure 5 and Figure 6A baffle 5 is provided on the side wall of the transmission channel 22 away from the first mounting frame 1. The second mounting frame 2 can be arranged with multiple baffles 5 along the length of the transmission channel 22. The multiple baffles 5 correspond one-to-one with the multiple first mounting frames 1. Both sides of the baffle 5 along the second direction are provided with side plates 51 extending towards the corresponding first mounting frame 1. A limiting space 52 is formed between the two side plates 51 and the baffle 5. The limiting space 52 is located directly below the downward end of the first guide plate 4. By adopting the above technical solution, when the sheet falls, it is subject to the dual constraints of the baffle 5 and the side plates 51, which restricts the movement of the sheet in the first direction and the second direction, further improving the stability of the sheet in the transmission channel 22.

[0052] Reference Figure 6 and Figure 7 A second guide plate 6 is provided on the side of the baffle 5 near the corresponding first mounting bracket 1. The second guide plate 6 includes an arc-shaped segment 61 and a guide segment 62 connected to each other. In this embodiment, the arc-shaped segment 61 has a semi-circular cross-sectional shape and extends along the axial direction of the circle. The axial direction of the arc-shaped segment 61 is parallel to the second direction. One end of the arc-shaped segment 61 is connected to the baffle 5, and the other end extends downward and is connected to the guide segment 62. The side of the outer arc surface of the arc-shaped segment 61 away from the baffle 5 faces the downward end of the first guide plate 4. The outer arc surface of the arc-shaped segment 61 faces upward and can serve as a guiding structure for the sheet material between the first guide plate 4 and the second guide plate 6. The guide segment 62 is a straight plate. The end of the guide segment 62 away from the arc-shaped segment 61 extends downward and is inclined in the direction away from the first mounting bracket 1. The downward end of the guide segment 62 faces the edge of the limiting space 52 away from the first mounting bracket 1. The downward end of the guide segment 62 extends horizontally and is parallel to the extension direction of the transmission channel 22.

[0053] As can be seen from the above, because the sheet material still has a certain moving speed after being transmitted by the first conveying device 11, if the first guide plate 4 is directly aligned with the conveying channel 22 and the sheet material is dropped, under the inertia of the sheet material, it may directly impact the baffle 5 or fall on top of the sheet material already stacked in the limiting space 52, making it impossible to complete the stacking of the predetermined number of sheet materials normally. However, by setting the second guide plate 6, a sliding path is formed along the direction away from the pressure plate 8, so that the sheet material can stably fall towards the edge of the limiting space 52, while guiding the sheet material to the edge. When the end of segment 62 is aligned with the edge of the limiting space 52, as can be seen from the aforementioned scheme, the base plate 9, driven by the drive end 71, can move the already positioned sheet material closer to the first mounting frame 1, thereby reserving a space for positioning at the edge of the limiting space 52 away from the first mounting frame 1. When the end of the guide segment 62 is set in this way, after the sheet material passes through the guide segment 62, it can fall into the limiting space 52 with its bottom line parallel to the extension direction of the transmission channel 22, making the arrangement of multiple sheet materials more neat.

[0054] As a further preferred embodiment, the upper end of the guide segment 62 is elastically connected to the arc-shaped segment 61, and the end of the guide segment 62 away from the arc-shaped segment 61 is a free end. In order to speed up the feeding speed and increase the speed of the entire production process, a large conveying speed is set on the first conveyor belt and the card issuing assembly 12, so that the sheet material has a large initial velocity. Through the elastic connection between the guide segment 62 and the arc-shaped segment 61, after the sheet material contacts the guide segment 62, it will drive the guide segment 62 to deform towards the baffle 5, thereby changing the guiding path scheme on the guide segment 62, so that the sheet material moves closer to the edge of the limiting space 52. At the same time, compared with the rigid guide segment 62, the elastically deformable guide segment 62 reduces the rigid collision with the sheet material, and can buffer the sheet material during the contact process, reduce the kinetic energy of the sheet material, thereby reducing the collision deformation of the sheet material after hitting the bottom, thus affecting the situation where the next sheet material collides with the already deformed sheet material after falling and deviates from the original falling path.

[0055] Furthermore, refer to Figure 7 The second guide plate 6 is located on the side of the end of the first guide plate 4 facing the first direction. The projections of the end of the first guide plate 4 and the second guide plate 6 on the horizontal plane do not overlap. Through this design, when the sheet material is ejected from the end of the first guide plate 4, it will not fall onto the arc segment 61 under the restriction of the first guide plate 4, but will only contact the guide segment 62.

[0056] Reference Figure 6 and Figure 7 The second mounting bracket 2 is provided with a drive assembly 7 on one side opposite the baffle 5. The drive assembly 7 has a drive end 71 and a pressure plate 8 is connected to the drive end 71. The drive end 71 can drive the pressure plate 8 to move in and out of the transmission channel 22 along a direction parallel to the second direction. Furthermore, a second guide plate 81 is provided on the top of the pressure plate 8. The second guide plate 81 extends upward and is inclined away from the baffle 5.

[0057] Using the movable pressure plate 8, before the sheet falls, the drive end 71 drives the pressure plate 8 to move towards the direction of entering the transmission channel 22, thereby compressing the limiting space 52. This ensures that after the sheet falls, it stably falls into the limiting space 52 along the gap between the baffle 5 and the pressure plate 8 and maintains an upright posture, further improving the stability of the sheet falling. Then, during the falling process, the drive end 71 drives the pressure plate 8 to move backward until it exits the transmission channel 22, expanding the limiting space 52 and providing sufficient space for the falling sheet. At the same time, the sheet that has already fallen moves backward and interacts with the baffle. A small gap is formed between 5, which can stably restrict the next sheet. During the continuous feeding process, the gap between the sheets in the same limiting space 52 is large and the whole is loose. At this time, the pressure plate 8, which has moved out of the transmission channel 22, re-enters the transmission channel 22 and is flush with the side wall of the transmission channel 22. It presses the sheet group so that the width of the sheet group is consistent with the width of the transmission channel 22. Thus, when the second conveying device 21 moves the sheet group, the sheet group is limited in the first direction through the transmission channel 22, so that the sheet group can be transmitted smoothly.

[0058] Reference Figure 4 and Figure 7 The drive end 71 is also provided with a base plate 9, which is located at the bottom of the limiting space 52. The length of the base plate 9 is greater than the sum of the length of the limiting space 52 in the first direction and the distance that the drive end 71 can move, so as to ensure that after the base plate 9 moves, the sheet material can still fall on the base plate 9 and move with the base plate 9. When the sheet material falls into the limiting space 52, the sheet material will fall on the base plate 9. At this time, the drive end 71 synchronously drives the base plate 9, which drives the sheet material on the base plate 9 to move, so that the sheet material that has fallen into the limiting space 52 can move away from the baffle 5, thereby forming a sufficient gap on the side to facilitate the next sheet material to fall in, ensuring the smoothness of the falling material. At the same time, it can make the next sheet material fall on the side, enhance the regularity of the sheet material arrangement, and also reduce the collision between the sheet materials, reducing the occurrence of scratches or damage.

[0059] Specifically, the drive assembly 7 includes a connecting frame, a shaft, a belt, a slider, and a drive motor. The shaft is fixedly mounted on the first mounting frame 1. The belt is wound around the shaft and extends along the first direction. The drive motor is fixedly mounted on the shaft and connected to the belt drive. The slider is slidably mounted on the shaft and connected to the belt. The connecting frame is fixedly connected to the slider. The end of the connecting frame away from the slider is the drive end 71. The drive end 71 includes two mounting parts that extend horizontally toward the pressure plate 8. The two mounting parts are located on the upper and lower sides of the clearance channel 24. The pressure plate 8 is mounted on the upper mounting part, and the base plate 9 is mounted on the lower mounting part.

[0060] Reference Figure 4 , Figure 5 and Figure 6The drive rod 23 can move to the side of each limiting space 52 opposite to the first direction. The baffle 5 can move up and down on the second mounting frame 2. Specifically, the second mounting frame 2 is equipped with a lifting cylinder. The output end of the lifting cylinder can move up and down on the first mounting frame 1. The baffle 5 is installed at the output end of the lifting cylinder. The baffle 5 can move to a position where the bottom is higher than the height of the drive rod 23. Moreover, the baffle 5 can drive the second guide plate 6 and the two side plates 51 to move synchronously, reducing interference between components. The pressure plate 8 and the bottom... Plates 9 are located on the upper and lower sides of the avoidance channel 24 respectively. When the drive rod 23 moves, it can pass between the pressure plate 8 and the bottom plate 9. Through this scheme, the components in the transmission channel 22 can avoid each other with the drive rod 23, which increases the height of the drive rod 23. For example, if the drive rod 23 is set in the middle of the height of the transmission channel 22, compared with when the drive rod 23 is located at the bottom for avoidance, it reduces the adverse consequences of the drive rod 23 being unable to push the entire sheet group at the bottom or the sheet group being unstable and overturned when pushed at the bottom.

[0061] As can be seen from the above, when the preset number of sheet materials are placed, the drive rod 23 moves under the drive of the chain and sprocket assembly. At the same time, the baffle 5 is raised to make way for one end of the drive rod 23, and the other end of the drive rod 23 passes between the pressure plate 8 and the bottom plate 9, thereby pushing the sheet material group between the pressure plate 8 and the baffle 5 until the sheet material group is pushed by the drive rod 23 and enters the packaging channel.

[0062] The implementation principle of this application embodiment is as follows: First, the worker places the sheet material on the first conveying device 11, and the first conveying device 11 transfers the sheet material to the card issuing station of the card issuing assembly 12. After being rapidly pushed by the card issuing assembly 12, the sheet material is given a certain initial velocity and then rushes out from the first mounting frame 1. Then, guided by the first guide plate 4, the sheet material changes from horizontal movement to vertical movement and falls into the second guide plate 6 in a relatively vertical posture. At the same time, the second guide plate 6 is located between the first mounting frame 1 and the second mounting frame 2. The sheet material is guided so that it can fall accurately and stably into the transmission channel 22 and be located on the side of the transmission channel 22 away from the first mounting frame 1. At the same time, the drive component 7 drives the base plate 9 and the pressure plate 8 to move backward, thereby moving the already placed sheet material backward to avoid the next sheet material. After a predetermined number of sheet materials fall into the transmission channel 22, the pressure plate 8 is reset to be flush with the side wall of the transmission channel 22 to compact the sheet material. Then, the second conveying device 21 synchronously pushes the stacked sheet material to the packaging component to complete the sorting and packaging of the sheet material.
