DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0031] In the description of the present application, it should be understood that the terms indicating the position or location relationship are based on the position or location relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a specific position, be constructed and operated in a specific position, therefore, it cannot be understood as a limitation of the utility model.

[0032] It should be noted that: similar labels and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3This embodiment provides a bag opening mechanism, including a bag upper assembly 110 and a bag opening assembly 120. The bag upper assembly 110 includes a suction section 110A and a hopper 115 for placing a packaged bag. The suction section 110A has a first suction member 111, which is used to suction the packaged bag and move it to a carrier 130. The carrier 130 is located between the bag upper assembly 110 and the bag opening assembly 120. The bag opening assembly 120 includes a second suction member 121a and a bag opening member 121a that are arranged at relatively intervals. The bag opening suction cup 121b and two bag opening rods 122 are spaced apart between the second suction member 121a and the bag opening suction cup 121b. The bag opening rods 122 have first guide plates 1221 extending along the opening direction of the packaged bag. The second suction member 121a and the bag opening suction cup 121b can respectively suction the opposite sides of the opening side of the packaged bag so that the two first guide plates 1221 extend into the opening of the packaged bag. The two first guide plates 1221 move away from each other to open the opening of the packaged bag.

[0034] Specifically, the bag opening mechanism includes a bag loading assembly 110 and a bag opening assembly 120. The bag loading assembly 110, as the starting point of the bag opening mechanism, includes a suction section 110A and a hopper 115. The hopper 115 is used to store the packaging bags to be processed, providing raw material reserves for the entire bag opening process. Multiple packaging bags can be stacked on the top surface of the hopper 115.

[0035] like Figure 2 As shown, the suction unit 110A is a key component for retrieving packaging bags from the hopper 115. The suction unit 110A consists of multiple support rods and a first suction element 111. The support rods are spaced apart and parallel to each other on the top of the hopper 115. The first suction element 111 is located on the side of the support rods facing the hopper 115 and is used to suction the packaging bags and move them onto the carrier 130. The carrier 130 not only provides a stable placement position for the packaging bags, but its design also considers the connection with the subsequent bag-opening assembly 120, ensuring that the packaging bags can smoothly proceed to the next step when entering the bag-opening assembly 120.

[0036] The bag opening assembly 120 is used to open the opening of the sealed bag. The second suction member 121a and the bag opening suction cup 121b are arranged at intervals relative to each other. This layout design is intended to act on opposite sides of the opening side of the sealed bag respectively. By reasonably controlling the suction force of the second suction member 121a and the bag opening suction cup 121b, it is ensured that the force can be applied evenly when adsorbing the opening part of the sealed bag, avoiding damage to the sealed bag or deformation of the opening due to uneven force.

[0037] like Figure 3As shown, the two bag opening rods 122 can play an important role in supporting and guiding during the bag opening process. The first guide plates 1221 on the bag opening rods 122 extend along the opening direction of the packaging bag to accurately guide into the inside of the packaging bag opening and provide stable guidance for opening the packaging bag.

[0038] When the second suction member 121a and the bag opening suction disc 121b start working, they respectively adsorb the opposite two sides of the packaging bag opening. By accurately controlling the adsorption force and adsorption position, it is ensured that the opening part of the packaging bag is stably clamped. After the adsorption is completed, the two bag opening rods 122 drive the first guide plates 1221 to extend into the opening of the packaging bag and move in directions away from each other.

[0039] During the movement, the first guide plates 1221 exert outward force on the two sides of the packaging bag opening, thereby gradually opening the opening of the packaging bag. This way of opening the packaging bag opening by moving the first guide plates 1221 away from each other can achieve uniform opening of the opening and avoid breaking or damaging the packaging bag due to excessive local force. At the same time, by accurately controlling the moving speed and displacement of the first guide plates 1221, the bag opening requirements of packaging bags of different sizes and materials can be met, and the versatility and reliability of the bag opening mechanism can be improved.

[0040] It should be noted that, first, in an embodiment of the present application, as shown in Figure 2 The number of first suction members 111 is multiple, and the multiple first suction members 111 are uniformly distributed on the top of the hopper 115 along the connecting line direction of the hopper 115 and the carrier 130 to correspond to the opening end and the bottom end of the packaging bag on the surface of the hopper 115 respectively; the bag placing assembly 110 further includes a material distribution assembly arranged at the side edge of the hopper 115, the material distribution assembly includes a material distribution rod 112 and a material pressing rod 113, the material distribution rod 112 is driven to be able to move horizontally along the top surface of the hopper 115; the material pressing rod 113 is driven to be able to rotate and press the top surface side edge of the hopper 115.

[0041] Specifically, the suction part 110A is composed of multiple support rods and first suction members 111, as shown in Figure 2 The multiple support rods are arranged in parallel at the top of the hopper 115; the first suction members 111 are located on the side of the support rods facing the hopper 115 and can be used to adsorb the packaging bag and move it to the carrier 130. Through the arrangement of multiple first suction members 111, the adsorption stability and reliability can be improved, and the flexibility of the adsorption process is also more convenient.

[0042] As shown in Figure 2As shown, the side edge of the hopper 115 is also provided with a distribution rod 112 and a pressing rod 113, both of which are arranged on the same side of the hopper 115. The pressing rod 113 is in an L-shaped structure and can rotate relative to the hopper 115; the distribution rod 112 can move along the top surface of the hopper 115 to sweep the top surface of the hopper 115. The arrangement of the distribution rod 112 and the pressing rod 113 can ensure the effective separation of the two adjacent packaging bags.

[0043] When the hopper 115 is provided with a plurality of stacked packaging bags, the two adjacent packaging bags may be tightly attached due to the action of static electricity, pressure, etc. In order to ensure that the bag feeding assembly 110 moves one packaging bag at a time, and does not move multiple packaging bags at the same time, the first suction member 111 at the bottom end of the packaging bag can first adsorb the packaging bag and slightly rise, at this time the pressing rod 113 can be rotated to contact and press the remaining packaging bag on the hopper 115 which is not adsorbed, to avoid being adsorbed by the first suction rod; at the same time, the distribution rod 112 sweeps from the bottom end of the top surface of the packaging bag to the opening end, to ensure that the adsorbed packaging bag is completely separated from the packaging bag below; at the same time, the first suction member 111 close to the opening end of the packaging bag adsorbs the opening end of the packaging bag, completing the adsorption process of the packaging bag.

[0044] Second, in an embodiment of the present application, as shown in Figure 2 The bag feeding assembly 110 further comprises a jacking cylinder 114, the extension end of which is fixedly connected with the hopper 115 to drive the hopper 115 to move in the vertical direction.

[0045] Specifically, in order to adjust the relative distance between the hopper 115 and the suction part 110A, the hopper 115 can be adjusted in height in the vertical direction through the jacking cylinder 114. When the number of packaging bags on the hopper 115 gradually decreases, in order to ensure that the suction part 110A can still adsorb the topmost packaging bag, the hopper 115 can be raised by the jacking cylinder 114 to approach the suction part 110A. The reliability of the suction process is ensured.

[0046] Third, in an embodiment of the present application, the bag opening assembly 120 comprises a controller and a driving part, the driving part is signal connected with the controller, and the two bag opening rods 122 are drivingly connected with the driving part, and the controller can drive the two bag opening rods 122 to approach or move away from each other through the driving part.

[0047] Specifically, the two bag opening rods 122 are respectively in transmission connection with the driving part, and the transmission connection can adopt various forms such as gear transmission, chain transmission, screw transmission, connecting rod transmission, etc. The specific transmission mode can be adjusted according to the design requirements and application scenarios of the bag opening assembly 120. The controller controls the two bag opening rods 122 through the driving part, so that the two bag opening rods 122 can move closer to or away from each other. Through this precise control and transmission mode, effective bag opening operation can be realized on packaging bags of different sizes and materials, and the movement state of the bag opening rod 122 can be flexibly adjusted according to different working conditions, improving the versatility, reliability and automation degree of the bag opening assembly 120. At the same time, this way of controlling the bag opening rod 122 by the controller through the driving part can ensure the safety and stability of the bag opening operation, avoid bag opening failure or equipment damage caused by human factors or other interference factors, and ensure efficient, accurate and reliable operation of the entire bag opening process.

[0048] The above bag opening mechanism can realize automatic, efficient, stable and lossless bag opening operation of the packaging bag, improve the material 400 processing efficiency and quality in the production process, and reduce the labor cost and errors and losses that may be caused by manual operation.

[0049] For example, as shown in Figure 3 and Figure 4 , the driving part includes a servo motor 123 and a ball screw, the servo motor 123 is in signal connection with the controller, and the ball screw is connected with the output end of the servo motor 123; further comprising a mounting plate 125, the servo motor 123 and the ball screw 124 are arranged on the mounting plate 125; two first sliding blocks 126 are movably arranged on the ball screw 124, the ball screw 124 is driven to rotate to make the two first sliding blocks 126 slide along the extension direction of the ball screw 124, and the bag opening rod 122 is fixedly connected with the first sliding block 126.

[0050] Specifically, as shown in Figure 3 and Figure 4As shown, the driving part includes a mounting plate 125, on which a servo motor 123 and a ball screw are arranged. The controller can adjust the rotation speed, rotation direction, start-stop and other operation parameters of the servo motor 123. The servo motor 123 has good response speed and position control accuracy, and can provide accurate power control basis for the whole bag opening operation. The ball screw is a kind of high-efficiency transmission element, which is connected with the output end of the servo motor 123. This connection mode ensures that the power generated by the servo motor 123 can be effectively transmitted to the ball screw. Compared with the traditional sliding screw rod, it has the advantages of small friction, high efficiency and high precision. When the servo motor 123 rotates, the rotary power output by the servo motor 123 is transmitted to the ball screw through a shaft coupling or other suitable connecting parts, driving the ball screw to rotate, so as to convert the rotary motion into linear motion or accurate position control, and provide stable and accurate driving for the subsequent bag opening rod 122 action.

[0051] As shown in Figure 4 , two first sliding blocks 126 are movably arranged on the ball screw 124, and the bag opening rod 122 is fixedly connected with the first sliding block 126. The two first sliding blocks 126 cooperate with the ball screw 124, and utilize the characteristic that the rotary motion of the ball screw is converted into linear motion. When the ball screw 124 is driven to rotate, the two first sliding blocks 126 can slide along the extension direction of the ball screw 124.

[0052] By controlling the rotation direction and number of turns of the ball screw 124, the position of the first sliding block 126 can be accurately controlled, and finally the position of the bag opening rod 122 can be accurately controlled. The bag opening rod 122 can move closer or farther away according to the actual bag opening situation, so as to complete the bag opening action of the packaging bag. This design transmits the accurate linear transmission advantage of the ball screw 124 to the bag opening rod 122 through the first sliding block 126, and provides an efficient, accurate and stable driving and transmission solution for the bag opening operation, improves the overall performance and working efficiency of the bag opening assembly 120, and also ensures the consistency and reliability of the bag opening operation under different working conditions.

[0053] Optionally, as shown in Figure 4 , the end of the bag opening rod 122 has a second sliding block 127, and the bag opening rod 122 is fixedly connected with the first sliding block 126 through the second sliding block 127, and the second sliding block 127 is slidably connected with the mounting plate 125.

[0054] Specifically, as shown in Figure 4As shown, in order to further improve the sliding stability of the bag opening rod 122, the end of the bag opening rod 122 is also provided with a second sliding block 127. The bottom surface of the second sliding block 127 is parallel to the plate surface of the mounting plate 125, so as to be able to slide on the mounting plate 125. The first sliding block 126 is movably arranged on the ball screw 124, and the side of the second sliding block 127 close to the first sliding block 126 is fixedly connected with the first sliding block 126, and the side away from the first sliding block 126 is connected with the bag opening rod 122.

[0055] Since the second sliding block 127 is parallel to the plate surface of the mounting plate 125, the side of the second sliding block 127 facing the mounting plate 125 is provided with a sliding groove, and correspondingly, the mounting plate 125 is provided with a sliding rail 1251 arranged along the extension direction of the ball screw, and the second sliding groove can be slidably connected with the sliding groove through the sliding rail 1251, thereby realizing horizontal movement on the plate surface of the mounting plate 125. Of course, in addition to the above arrangement, the side of the second sliding block 127 facing the mounting plate 125 can be provided with a sliding rail 1251, and the mounting plate 125 can be provided with a sliding groove arranged along the extension direction of the ball screw. The application does not limit the specific arrangement form.

[0056] When the ball screw drives the two first sliding blocks 126 to move close to or away from each other, the second sliding block 127 can be synchronously driven to move along the mounting plate 125, which can make the movement of the bag opening rod 122 more stable and reliable; at the same time, this arrangement can also enable the operator to manually fine-tune the actual position of the bag opening rod 122 through the second sliding block 127, so as to adapt to packaging bags of different opening sizes.

[0057] Optionally, as shown in the figure, Figure 5 The bag opening assembly 120 further comprises a detection piece 128 arranged on the mounting plate 125, and the detection piece 128 is signal-connected with the controller; the detection piece 128 is located on the side away from the two first sliding blocks 126, and is used for measuring the interval distance of the first sliding blocks 126.

[0058] Specifically, as shown in the figure, Figure 5 The detection piece 128 is placed on the side away from the two first sliding blocks 126, so as to more conveniently and accurately measure and monitor the position of the first sliding blocks 126. Since the first sliding blocks 126 will slide along the extension direction of the ball screw 124 during the bag opening process, the change of the interval distance thereof is crucial to the bag opening operation, and therefore placing the detection piece 128 at this position can directly measure the interval distance of the first sliding blocks 126.

[0059] The main function of the detection piece 128 is to measure the interval distance of the first sliding blocks 126, so as to detect whether the two first sliding blocks 126 have been moved to the position, thereby ensuring that the opening of the packaging bag has been completely opened, and providing protection for the subsequent bagging process. Preferably, the detection piece 128 is an optical sensor.

[0060] In an implementation of the present application, as shown in Figure 3 The bag opening assembly 120 further comprises a lifting cylinder 129a and a translation cylinder 129b. The active end of the lifting cylinder 129a is in driving connection with the second suction element 121a to drive the second suction element 121a to move along the vertical direction to approach or move away from the bag suction disc 121b. The active end of the translation cylinder 129b is connected with the mounting plate 125 to drive the mounting plate 125 to move along the horizontal direction to approach or move away from the carrier 130. The end of the lifting cylinder 129a is provided with a fixed plate 1291 parallel to the carrier 130, and the second suction element 121a is arranged on the side of the fixed plate 1291 facing the carrier 130.

[0061] Specifically, in different stages of the bag opening operation, in order to flexibly adjust the vertical position of the second suction element 121a as needed, the second suction element 121a is in driving connection with the active end of the lifting cylinder 129a, so that the second suction element 121a can move along the vertical direction under the drive of the lifting cylinder 129a, thereby realizing the action of approaching or moving away from the bag suction disc 121b. By controlling the lifting cylinder 129a, the second suction element 121a can be lowered to an appropriate height, so that it can accurately adsorb the corresponding part of the opening side of the packaging bag; and after completing the adsorption or other operations, the second suction element 121a can be lifted to a certain height to provide space for subsequent operations or to avoid interference with other components. This adjustable vertical position function enhances the operation flexibility and adaptability of the bag opening assembly 120, and can accurately control the vertical position of the second suction element 121a according to packaging bags of different sizes and thicknesses and different working scenarios, to ensure the smooth progress of the bag opening operation.

[0062] As shown in Figure 3 The end of the lifting cylinder 129a is equipped with a fixed plate 1291, and the second suction element 121a is arranged on the side of the fixed plate 1291 facing the carrier 130; the fixed plate 1291 is parallel to the carrier 130, and the parallel arrangement can ensure that the movement track and adsorption action of the second suction element 121a during the bag opening operation are in good correspondence with the position of the packaging bag on the carrier 130, avoiding inaccurate adsorption or operation errors due to angle deviation. When the lifting cylinder 129a drives the fixed plate 1291 to move up and down, the second suction element 121a can accurately align the opening side of the packaging bag for adsorption operation. In addition, the fixed plate 1291 provides a stable mounting basis for the second suction element 121a, so that it can remain stable during adsorption and movement operations, avoiding displacement or vibration due to stress, thereby improving the reliability and stability of the second suction element 121a in adsorbing the packaging bag.

[0063] In order to ensure that the bag opening rod 122 can smoothly extend into the opening of the packaging bag and open the packaging bag opening, the mounting plate 125 is in transmission connection with the movable end of the translation cylinder 129b. When the piston of the translation cylinder 129b performs the extension and retraction action, a horizontal force is applied to the mounting plate 125, so as to push or pull the mounting plate 125 to move on the horizontal plane, so that it can approach or move away from the carrier 130. At the same time, the setting of the translation cylinder 129b can also ensure that the second material suction element 121a and the bag opening suction cup 121b can accurately operate on the packaging bag. On the other hand, after completing the bag opening operation, the mounting plate 125 can be moved away, which is convenient for subsequent material 400 bagging or equipment maintenance and other operations. The horizontal movability improves the operation convenience of the whole bag opening assembly 120 and the flexibility of the equipment layout.

[0064] Another aspect of the embodiments of the present application is to provide a material bagging device 200, as shown in Figure 1 and Figure 5 , which comprises a pushing mechanism 210 and a bag opening mechanism. The pushing mechanism 210 comprises a push rod 211 and second guide plates 212 rotatably arranged on opposite sides of the push rod 211. The push rod 211 is arranged opposite to the opening of the packaging bag on the carrier 130. The plate surface of the second guide plate 212 can be rotated to be parallel or perpendicular to the direction of the line connecting the push rod 211 and the carrier 130. When the plate surface of the second guide plate 212 is parallel to the direction of the line connecting the push rod 211 and the carrier 130, the material 400 is limited between the two second guide plates 212 and arranged opposite to the push rod 211. The push rod 211 pushes the material 400 to move towards the carrier 130 and enters the packaging bag through the opening of the packaging bag.

[0065] Specifically, as shown in Figure 5 , the pushing mechanism 210 is composed of the push rod 211 and the second guide plate 212. The push rod 211 is responsible for pushing the material 400 into the packaging bag. Preferably, the surface of the push rod 211 can be adapted to the structure of the material 400 to maximize the fit with the material 400, so that the material 400 moving process is more stable.

[0066] As shown in Figure 5 , the second guide plates 212 are also rotatably arranged on opposite sides of the push rod 211. When the material 400 is arranged on the conveying belt, the plate surface of the second guide plate 212 is perpendicular to the direction of the line connecting the push rod 211 and the carrier 130. At this time, the second guide plate 212 will not block the conveying of the material 400. When the material 400 moves to between the push rod 211 and the carrier 130, the second guide plate 212 can rotate relative to the push rod 211 to respectively fit the opposite sides of the material 400. At this time, the material 400 is limited between the two second guide plates 212 and cannot continue to be conveyed by the conveying belt.

[0067] The second guide plate 212 can limit the material 400, and the push rod 211 can directly push the material 400 towards the carrier 130, so that the material 400 is pushed into the packaging bag with the opened bag opening, and the material 400 is packaged. Due to the arrangement of the second guide plate 212, the material 400 is in a stable and accurate position before being pushed, and deviation or misplacement of the material 400 during pushing is avoided.

[0068] The material bagging device 200 provided in the application includes a pushing mechanism 210 and a bag opening mechanism. The pushing mechanism 210 includes a push rod 211 and second guide plates 212 rotatably arranged on opposite sides of the push rod 211. The push rod 211 is arranged opposite and spaced apart from the opening of the packaging bag on the carrier 130. The surface of the second guide plate 212 can be rotated to be parallel or perpendicular to the direction of the line connecting the push rod 211 and the carrier 130. Through the arrangement of the push rod 211, the material 400 can be accurately pushed to the opening of the packaging bag, providing a suitable positional relationship for the material 400 to smoothly enter the packaging bag, avoiding the failure of the material 400 to be bagged due to improper position of the push rod 211, and improving the accuracy of bagging. The second guide plate 212 is rotatably arranged, which can be flexibly adjusted in position according to different stages of the bagging process, increasing the functionality and adaptability of the device. When the surface of the second guide plate 212 is parallel to the direction of the line connecting the push rod 211 and the carrier 130, the material 400 is limited between the two second guide plates 212 and arranged opposite to the push rod 211. The push rod 211 pushes the material 400 towards the carrier 130 and enters the packaging bag through the opening of the packaging bag. Through the above design, the material bagging device 200 can realize accurate positioning of the material 400, stable bagging operation and flexible guide adjustment during the material 400 bagging process, which improves the efficiency and success rate of bagging, enhances the adaptability to different materials 400 and different bagging requirements, reduces manual intervention, and reduces production cost and the possibility of errors. The specific structure and beneficial effects of the bag opening mechanism have been described in detail above, and will not be repeated here.

[0069] In an embodiment of the application, as shown in Figure 5 The pushing mechanism 210 includes a push head driving member 213. The movable end of the push head driving member 213 extends and is provided with a connecting plate 2131. The push rod 211 is fixedly arranged on the connecting plate 2131. The push head driving member 213 can move along the direction of the line connecting the push rod 211 and the carrier 130 to drive the push rod 211 to approach or move away from the carrier 130.

[0070] Specifically, as shown in Figure 5As shown, the connecting plate 2131 can connect the push rod 211 with the movable end of the push head driving member 213, so as to better transmit the power of the push head driving member 213 to the push rod 211, and provide a stable support and connection point for the push rod 211. The specific structure of the connecting plate 2131 can be adjusted according to the specific setting position of the movable end of the push head driving member 213 and the push rod 211, as long as the push rod 211 can be connected with the movable end of the push head driving member 213.

[0071] The connecting plate 2131 is usually made of a solid metal material with a certain thickness and strength to withstand various forces generated during the pushing of the material 400, ensuring the stability of the entire structure. When the push head driving member 213 moves along the connecting line direction, it drives the push rod 211 connected thereto to move, thereby realizing the operation of the push rod 211 approaching or moving away from the carrier 130. When approaching the carrier 130, the push rod 211 can accurately push the material 400 to the packaging bag on the carrier 130, preparing for the material 400 to enter the packaging bag; and when moving away from the carrier 130, it can avoid interfering with other operations or components, and facilitate cleaning, maintenance or replacement of the equipment, etc., making the entire pushing mechanism 210 more flexible, and being able to flexibly adjust the position of the push rod 211 according to different working stages and material 400 characteristics.

[0072] Further, as shown in Figure 6 and Figure 7 , the pushing mechanism 210 further comprises a support plate 216, a sliding plate 215, a sliding cylinder 217 and a rotating column 214; the number of the sliding plate 215 is two, and the two sliding plates 215 are arranged on the support plate 216 along the connecting line direction of the push rod 211 and the carrier 130, and are arranged on the opposite sides of the push rod 211 along the transmission direction of the transmission belt 300; at least one end of the sliding plate 215 extends to the outside of the support plate 216 to be movably connected with the rotating column 214, and the end of the rotating column 214 away from the sliding plate 215 is connected with the second guide plate 212; the number of the sliding cylinder 217 is two, and the two sliding cylinders 217 are arranged on the support plate 216 and are drivingly connected with the two sliding plates 215, respectively; the two sliding cylinders 217 drive the two sliding plates 215 to move in the direction away from or close to each other, thereby driving the rotating column 214 to rotate the second guide plate 212.

[0073] Specifically, as shown in Figure 6 and Figure 7 , the support plate 216 serves as the basic support structure of the entire pushing mechanism 210, and plays an important role in bearing and positioning other components. Preferably, the support plate 216 can be made of a material with sufficient strength and rigidity, such as a high-strength metal plate.

[0074] Two sliding plates 215 are arranged on the support plate 216 along the direction of the line connecting the push rod 211 and the carrier 130, and at least one end of each sliding plate 215 extends to the outside of the support plate 216, thereby providing space and conditions for the installation and movement of the rotating column 214. The connection between the sliding plate 215 and the rotating column 214 can be a hinged connection, so that the rotating column 214 can rotate relative to the sliding plate 215.

[0075] The end of the rotating column 214 away from the sliding plate 215 is connected with the second guide plate 212, which can transmit the movement of the sliding plate 215 to the second guide plate 212, and the connection mode ensures effective transmission of the rotating movement. When the sliding plate 215 moves, the second guide plate 212 can realize corresponding rotating operation through the transmission of the rotating column 214.

[0076] The push mechanism 210 is provided with two sliding cylinders 217, and the number of settings is to realize independent driving of the two sliding plates 215. They are respectively drivingly connected with the two sliding plates 215 to effectively transmit the linear motion power generated by the sliding cylinder 217 to the sliding plate 215. The two sliding cylinders 217 are oppositely arranged to ensure that the second guide plate 212 can be oppositely arranged. When the two sliding cylinders 217 move in directions away from each other, the two sliding plates 215 move in directions away from each other. At this time, the rotating column 214 hingedly arranged with the sliding plate 215 rotates relative to the sliding plate 215 due to the action force provided by the sliding plate 215, thereby driving the second guide plate 212 to rotate, so that the plate surface of the second guide plate 212 is perpendicular or parallel to the direction of the line connecting the push rod 211 and the carrier 130.

[0077] For example, one end of each of the two sliding plates 215 extends to the outside of the support plate 216 to be movably connected with the rotating column 214; the two rotating columns 214 connected with the two sliding plates 215 are located on the same side of the support plate 216; or the two rotating columns 214 connected with the two sliding plates 215 are located on opposite sides of the support plate 216; or the opposite ends of the sliding plate 215 both extend to the outside of the support plate 216 to be movably connected with the rotating column 214.

[0078] Specifically, the present application does not make any limitation on the specific number of the second guide plates 212, as long as at least one pair of spaced second guide plates 212 are oppositely arranged to reliably limit the material 400. If the number of the second guide plates 212 is one pair, one end of each of the two sliding plates 215 extends to the outside of the support plate 216 to be movably connected with the rotating column 214, that is, a total of two rotating columns 214 are provided, and each rotating column 214 is connected with one second guide plate 212.

[0079] In an embodiment of the present application, the two rotating columns 214 connected by the two sliding plates 215 are located on the same side of the support plate 216, so that the two second guide plates 212 are arranged on the same side of the conveying belt 300; in another embodiment of the present application, the two rotating columns 214 connected by the two sliding plates 215 are located on opposite sides of the support plate 216, so that the two second guide plates 212 are arranged on opposite sides of the conveying belt 300.

[0080] As shown in Figure 6 and Figure 7 If the number of the second guide plates is two pairs, the opposite ends of the sliding plate 215 extend to the outside of the support plate 216 to be movably connected with the rotating column 214, and at this time, one sliding plate 215 is connected with two rotating columns 214.

[0081] The above only describes optional embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0082] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not describe various possible combinations again.
