[0034] Please refer to Figure 1 and Figure 2 The embodiment provides a bag corner straightening mechanism 100, which comprises a driving member 110 and two pairs of straightening assemblies, the two pairs of straightening assemblies are arranged on opposite sides of a conveying belt 300, and each pair of straightening assemblies comprises two straightening rods 120, and the driving member 110 is in driving connection with the straightening rods 120;The outer wall of the straightening rod 120 can contact the first packaging bag outside the material 400, and the driving member 110 can drive each pair of straightening rods 120 to move in directions away from each other, so that the opposite ends of the first packaging bag are straightened.

[0035] Specifically, as shown in Figure 1 and Figure 2 The straightening assembly of the bag corner straightening mechanism 100 comprises two straightening rods 120, the two straightening rods 120 are arranged at intervals and can move relative to each other, and the two straightening rods 120 are located on the same horizontal line, so that the two straightening rods 120 can contact the first packaging bag outside the material 400 at the same time.

[0036] In order to straighten the first packaging bag outside the material 400, the bag corner straightening mechanism 100 further comprises a driving member 110 capable of driving two straightening rods 120 located on the same side of the conveying belt 300 to move away from or close to each other. When the material 400 is placed on the conveying belt 300, the opposite sides of the first packaging bag can first contact the straightening rods 120. At this time, the driving member 110 drives the two straightening rods 120 on the same side to move away from each other. During the movement of the two straightening rods 120, an outward pulling force can be applied to the opposite ends of the first packaging bag, so that the bag corners can be gradually straightened from the original possible bending or irregular shape. Finally, after the straightening operation, the opposite ends of the first packaging bag can be straightened to a relatively regular shape, meeting the requirements of subsequent packaging, storage or transportation operations.

[0037] It should be noted that in an embodiment of the present application, first, the bag corner straightening mechanism 100 further comprises two limiting plates 130, which are arranged along the conveying direction of the conveying belt 300, and the two limiting plates 130 are arranged on opposite sides of the conveying belt 300; the straightening rods 120 are attached to the outer wall of the limiting plate 130 in the vertical direction.

[0038] Specifically, as shown in Figure 1 and Figure 2 The limiting plate 130 of the bag corner straightening mechanism 100 is arranged along the conveying direction of the conveying belt 300, and the two limiting plates 130 are arranged on the two sides of the conveying belt 300; the straightening rods 120 are attached to the outer wall of the limiting plate 130 and extend in the vertical direction to the top surface of the limiting plate 130, so that each side of the conveying belt 300 has two straightening rods 120 arranged at intervals. When the material 400 is placed on the conveying belt 300, the first packaging bag outside the material 400 can first contact the straightening rods 120 and then contact the limiting plates 130. During the movement of the two straightening rods 120, an outward pulling force can be applied to the opposite ends of the first packaging bag, and the opposite ends of the first packaging bag can be adjusted to a state parallel to the plate surface of the limiting plate 130.

[0039] After the bag corner of the first packaging bag is straightened, it is placed between the two limiting plates 130. The limiting plates 130 not only constrain the position of the material 400 in the entire mechanism, but also play an important role in maintaining the shape of the first packaging bag. After the straightening rod 120 straightens the bag corner of the packaging bag to be parallel to the surface of the limiting plate 130, the limiting plate 130 can effectively prevent the bag corner of the packaging bag from deforming or deviating again. Since the limiting plates 130 are arranged along the transmission direction of the transmission belt 300 and located on both sides of the transmission belt 300, they can support and limit the side of the packaging bag, so that the packaging bag always maintains a regular shape after being straightened during subsequent transmission and processing. The function of maintaining the shape of the packaging bag can ensure that the shape and state of the packaging bag meet the requirements during subsequent processes, avoid affecting the packaging quality of the product due to the deformation of the bag corner, and improve the stability and reliability of the entire packaging process.

[0040] Secondly, as shown in Figure 4 and Figure 6 , the straightening rod 120 includes a rod body 121 and a straightening piece 122 arranged at the end of the rod body 121. The straightening piece 122 is protruded from the rod body 121 and extends towards the arrangement direction of the transmission belt 300. When the material 400 is placed on the transmission belt 300, the straightening piece 122 can contact the first packaging bag outside the material 400.

[0041] Specifically, as shown in Figure 4 and Figure 6 , the rod body 121 of the straightening rod 120 is attached to the outer wall of the limiting plate 130 in the vertical direction and can move left and right along the outer wall of the limiting plate 130 to improve the stability of the movement of the straightening rod 120. The end of the rod body 121 is provided with a straightening piece 122, and the straightening piece 122 is arranged on the side where the two rod bodies 121 are close to each other.

[0042] The material of the rod body 121 can be selected from high-strength metal materials such as stainless steel and aluminum alloy. These materials have good rigidity and wear resistance, which can ensure that the rod body 121 will not deform or be damaged due to external force during a long working process, thereby stably supporting the straightening piece 122 and transmitting power. The straightening piece 122 is protruded from the rod body 121 to more effectively contact the first packaging bag. The protruding structure design ensures that the straightening piece 122 can form an effective force point when contacting the packaging bag, avoiding the problem of force dispersion caused by being flush with the rod body 121.

[0043] Meanwhile, the straightening piece 122 extends towards the arrangement direction of the transmission belt 300, and the extension direction is consistent with the transmission path of the material 400. When the material 400 moves on the transmission belt 300, the straightening piece 122 can contact the bag corner of the packaging bag from a suitable angle along the transmission direction of the material 400.

[0044] Thirdly, as shown in Figure 2 And Figure 5 The driving member 110 includes a support plate 111 and a driving motor 112, the support plate 111 is arranged at the bottom of the conveying belt 300; the driving motor 112 is arranged on the support plate 111 and is in driving connection with each pair of straightening rods 120 to drive each pair of straightening rods 120 to move in directions away from each other.

[0045] Specifically, the shape and size of the support plate 111 can be adjusted according to the specific layout of the conveying belt 300 and the straightening rod 120, and preferably, the support plate 111 is made of a material with certain strength and rigidity, such as a steel plate or an aluminum alloy plate, to withstand the weight of the driving motor 112 and various forces generated during operation. In order to reduce the volume of the bag corner straightening mechanism 100 and improve the space utilization, the size of the support plate 111 can be matched with the size of the conveying belt 300 to be arranged at the bottom of the conveying belt 300.

[0046] The driving motor 112 is the core component of the driving member 110, which can convert electrical energy into mechanical energy to provide the required power for the subsequent movement of the straightening rod 120. The specific form of the driving motor 112 is not limited in the present application, which can be a direct current motor, an alternating current motor or a stepping motor, etc. The direct current motor, the alternating current motor or the stepping motor, etc.

[0047] The driving motor 112 is in driving connection with each pair of straightening rods 120, and the driving connection mode can be a connecting rod mechanism, a gear transmission, a chain transmission or a belt transmission, etc., which is not limited in the present application, as long as it can ensure that the rotational motion generated by the driving motor 112 is converted into the linear motion of the straightening rod 120 in the direction away from each other.

[0048] When the driving motor 112 starts to rotate, the straightening rod 120 can move in the direction away from each other under the driving of the power to exert an outward pulling force on the two ends of the first packaging bag, stretch the originally curved or irregular bag corners to a regular state, make the two ends of the packaging bag parallel to the surface of the limiting plate 130, and then achieve the purpose of straightening the bag corner.

[0049] Fourthly, as shown in Figure 3 The bag corner straightening mechanism 100 further includes a material taking member 140, which is arranged on one side of the conveying belt 300; the material taking member 140 includes a material taking gripper 141 and a material taking moving cylinder 142, the material taking moving cylinder 142 is in driving connection with the material taking gripper 141; the material taking moving cylinder 142 can drive the material taking gripper 141 to move in the vertical direction to approach or away from the conveying belt 300; the material taking gripper 141 is used to clamp and place the material 400 sleeved with the first packaging bag on the conveying belt 300.

[0050] Specifically, in order to ensure that the bag corner straightening operation can be carried out in an orderly manner, the bag corner straightening mechanism 100 further comprises a material taking device 140, which is arranged to improve the automation level of the entire mechanism, facilitate the introduction of the material 400 into the working process of the straightening operation, reduce the complexity and uncertainty of manual operation, and improve the production efficiency and operation continuity.

[0051] As shown in Figure 3 , the material taking device 140 is arranged on one side of the conveying belt 300 and comprises a material taking gripper 141 and a material taking moving cylinder 142, so as to facilitate the clamping of the material 400, which has been sleeved with the first packaging bag, from other stations by the material taking gripper 141 and placing it on the conveying belt 300 in the vertical direction for subsequent bag corner straightening operation.

[0052] Through the cooperation of the material taking moving cylinder 142 and the material taking gripper 141, the material 400 can gradually descend in the vertical direction until the first packaging bag contacts the straightening member 122. During the descending process of the material 400, the straightening rod 120 can move in the horizontal direction until the material 400 is completely placed on the conveying belt 300. At this time, the first packaging bag has completed the bag corner straightening operation and is transmitted to the next station along the conveying belt 300 under the limiting and retaining of the limiting plate 130.

[0053] Such operation enables the material 400 to smoothly enter the transportation process of the conveying belt 300, thereby seamlessly connecting the material taking operation with the subsequent straightening operation and forming a complete material 400 processing flow, which improves the automation level and working efficiency of the entire mechanism.

[0054] The above-mentioned bag corner straightening mechanism 100 can straighten the bag corner of the packaging bag, facilitate its smooth and rapid insertion into the second packaging bag, and improve the packaging efficiency and packaging aesthetics.

[0055] For example, as shown in Figure 6 , the straightening member 122 comprises an extension plate 1221 and a straightening plate 1222. The extension plate 1221 is protrudingly arranged on the rod body 121 and is arranged towards the conveying belt 300. The straightening plate 1222 is perpendicularly arranged at the end of the extension plate 1221 away from the rod body 121.

[0056] Specifically, as shown in Figure 6As shown, to improve the working performance and straightening effect of the straightening member 122, the extension plate 1221 and the straightening plate 1222 are vertically arranged to form an L-shaped structure. This arrangement allows the straightening plate 1222 to apply force to the corner of the bag at the optimal angle when it contacts the first packaging bag. When the straightening rod 120 moves under the drive of the drive member 110, the vertically arranged straightening plate 1222 can effectively transmit the force to the corner of the packaging bag, thereby straightening the corner of the bag. The extension plate 1221 not only supports the straightening plate 1222, but also, because it protrudes from the rod body 121, can accurately guide the straightening plate 1222 to the corner of the packaging bag, ensuring the accuracy and timeliness of the straightening operation.

[0057] For example, such as Figure 5 As shown, the drive unit 110 also includes two racks 113 and two sliding plates 114; the sliding plates are arranged perpendicular to the transmission direction of the conveyor belt 300, and the opposite ends of the sliding plates 114 are respectively fixedly connected to two oppositely arranged straight rods 120 of the two pairs of straight rods 120; the two sliding plates 114 are spaced apart on both sides of the sliding plates 114; the two racks 113 are arranged parallel to the transmission direction of the conveyor belt 300, and one end of each rack 113 is respectively connected to the output end of the drive motor 112, and the other end is respectively fixedly connected to the two sliding plates 114; the drive motor 112 can drive the sliding plates 114 and the straight rods 120 to move in opposite directions through the racks 113.

[0058] Specifically, such as Figure 5 As shown, in order to ensure the synchronous movement of the straightening rods 120 set on both sides of the conveyor belt 300, the number of sliding plates 114 is preferably two. The two sliding plates 114 are spaced apart and parallel to each other. The extension direction of each sliding plate 114 is perpendicular to the conveying direction of the conveyor belt 300, and both ends of the sliding plate 114 extend to the outside of the conveyor belt 300, so as to ensure that the rod body 121 of the straightening rod 120 can be attached to the outer wall of the limiting plate 130.

[0059] The racks 113 are arranged parallel to the transmission direction of the conveyor belt 300, ensuring that the power transmission path is compatible with the movement direction of the conveyor belt 300, which facilitates the movement of the straightening lever 120 in opposite directions. By tightly connecting the racks 113 and the sliding plate 114, power can be transmitted from the racks 113 to the sliding plate 114, thereby driving the straightening lever 120 to move. This connection method can use key connections, bolt connections, etc., to ensure that there will be no slippage or separation between the two during power transmission, guaranteeing the high efficiency and reliability of power transmission.

[0060] Optionally, such as Figure 4As shown, the side edge of the limiting plate 130 close to the one side of the straightening member 122 is provided with a first guide plate 131, and the plate surface of the first guide plate 131 is inclined to the side away from the conveying belt 300.

[0061] Specifically, since the outer part of the material 400 is sleeved with the first packaging bag, in order to facilitate the stable and fast connection of the bag corner straightening operation of the first packaging bag and the process of placing the material 400 on the conveying belt 300 by the grabbing 141, the first guide plate 131 is inclined to the top edge of the limiting plate 130. Therefore, after the straightening rod 120 straightens the bag corner of the first packaging bag, the material 400 can be more easily placed on the conveying belt 300 in the limiting process of the limiting plate 130, preventing the bag corner of the first packaging bag from interfering with the limiting plate 130 during placement on the conveying belt 300, avoiding the bag corner being stuck or generating unnecessary friction by the limiting plate 130, and maintaining the straightened and bagged state of the bag corner of the first packaging bag.

[0062] Another aspect of the embodiment of the present application also provides a bagging device 200, as shown in Figure 1 The bagging device 200 comprises a pushing assembly and a bag corner straightening mechanism 100; the pushing assembly comprises a transmission-connected pushing cylinder 211 and a pushing rod 212, the pushing rod 212 is arranged at the edge of the conveying belt 300 and is arranged in spaced apart relationship with the opening of the second packaging bag; after the material 400 packaged by the first packaging bag is straightened by the bag corner straightening mechanism 100, the material 400 is transported to the pushing rod 212 along the conveying belt 300, and the pushing cylinder 211 drives the pushing rod 212 to move perpendicular to the conveying direction of the conveying belt 300, so as to push the material 400 into the second packaging bag from the opening of the second packaging bag.

[0063] Specifically, as shown in Figure 1 The present application also provides a bagging device 200, which is composed of two main parts, i.e. a pushing assembly and a bag corner straightening mechanism 100. The two parts work together to complete the bagging operation.

[0064] The pushing assembly is mainly responsible for pushing the material 400 into the second packaging bag, and the bag corner straightening mechanism 100 is responsible for straightening the bag corner of the first packaging bag, so as to ensure that the outer packaging bag of the material 400 has a good shape before entering the second packaging bag, thereby ensuring the smooth progress of the entire bagging process, making the bagging operation more systematic and complete, and improving the efficiency and quality of the bagging.

[0065] As shown in Figure 1As shown, the pushing assembly includes a transmission-connected pushing cylinder 211 and a pushing rod 212, the pushing cylinder 211 serves as a power source and can provide the pushing rod 212 with the power required for pushing. The pushing rod 212 is a component that directly contacts the material 400 and pushes the material 400 into the second packaging bag. It is arranged at the edge of the conveying belt 300 and can utilize the conveying function of the conveying belt 300 to make the pushing rod 212 timely and accurately apply a pushing force to the material 400 after the material 400 is conveyed to the appropriate position, so that the pushing rod 212 accurately pushes it into the second packaging bag. Among them, the pushing cylinder 211 drives the pushing rod 212 to move vertically to the conveying direction of the conveying belt 300, which can ensure that the material 400 will not be disturbed in the horizontal or other directions when entering the second packaging bag, avoiding the material 400 from being jammed or deviating from the position when entering the second packaging bag, thereby improving the accuracy and reliability of bagging.

[0066] The bagging device 200 described above can accurately load the bag corners of the packaging bag into the second packaging bag after straightening the bag corners, thereby improving the accuracy and stability of the bagging process, and the continuity and efficiency of the entire bagging process. The specific structure and beneficial effects of the bag corner straightening mechanism 100 have been described in detail above, and will not be repeated here.

[0067] In an embodiment of the present application, as shown in Figure 1 and Figure 4 The bagging device 200 further comprises a bag corner folding mechanism 220, and the bag corner folding mechanism 220 comprises second guide plates 221 rotatably arranged on opposite sides of the pushing rod 212. The surface of the second guide plate 221 can be rotated to be parallel or perpendicular to the direction of the line connecting the pushing rod 212 and the opening of the second packaging bag. When the surface of the second guide plate 221 is rotated to be perpendicular to the direction of the line connecting the pushing rod 212 and the opening of the second packaging bag, the material 400 can be transported along the conveying belt 300 to the pushing rod 212. At this time, the surface of the second guide plate 221 is rotated to be parallel to the direction of the line connecting the pushing rod 212 and the opening of the second packaging bag, so as to fold the bag corner of the first packaging bag to be in contact with the side wall of the material 400.

[0068] Specifically, as shown in Figure 1 and Figure 4 The bag corner folding mechanism 220 is mainly composed of second guide plates 221, which are rotatably arranged on opposite sides of the pushing rod 212 to ensure the consistency and symmetry of the bag corner folding. The design of the rotating arrangement allows the second guide plate 221 to flexibly change the direction of its surface to adapt to different operation stages and needs.

[0069] When the material 400 does not move to the push rod 212, the plate surface of the second guide plate 221 is perpendicular to the direction of the line connecting the push rod 212 and the opening of the second packaging bag, at this time, the second guide plate 221 does not hinder the transmission process of the material 400, and the material 400 can move along the conveying belt 300 smoothly.

[0070] When the material 400 is transported along the conveying belt 300 to the push rod 212, at this time, the plate surface of the second guide plate 221 is rotated to be parallel to the direction of the line connecting the push rod 212 and the opening of the second packaging bag, and is arranged on the top surface of the conveying belt 300. In the rotation process of the second guide plate 221, the first packaging bag can be contacted and folded at the bag corner, so that the bag corner of the first packaging bag is fitted with the side wall of the material 400; in this way, not only the appearance of the packaged product is more neat and beautiful, but also it is more convenient to pack into the second packaging bag; at the same time, the stability and sealing performance of the package are also enhanced to a certain extent.

[0071] Further, when the plate surface of the second guide plate 221 is rotated to be parallel to the direction of the line connecting the push rod 212 and the opening of the second packaging bag, at this time, the two sides of the material 400 are limited by the plate surface of the second guide plate 221, so that when the push rod 212 pushes the material 400 to the opening direction of the second packaging bag, the movement path of the material 400 can be more accurate, and the position deviation of the material 400 in the pushing process is avoided, and the bagging efficiency and reliability are further improved.

[0072] Further, as shown in Figure 4 , the bag corner folding mechanism 220 further comprises a rotating column 222 and a driving cylinder, the driving cylinder is drivingly connected with the rotating column 222; the end portion of the second guide plate 221 is fixedly connected with the rotating column 222; the driving cylinder can drive the rotating column 222 and the second guide plate 221 to rotate relative to the push rod 212.

[0073] Specifically, the driving cylinder is a component for providing power to the rotating column 222, and it is the power source for the rotating operation of the bag corner folding mechanism 220. The driving cylinder is drivingly connected with the rotating column 222, and this driving connection can be achieved in various mechanical connection modes, for example, a connecting rod mechanism, a shaft coupling or a direct connection of the cylinder rod with the rotating column 222, so as to ensure that the power generated by the driving cylinder can be effectively transmitted to the rotating column 222.

[0074] The end portion of the second guide plate 221 is fixedly connected with the rotating column 222, so that the rotating movement of the rotating column 222 can drive the second guide plate 221 to rotate synchronously. By fixing the end portion of the second guide plate 221 on the rotating column 222, it is ensured that the second guide plate 221 does not relatively displace or shake during the rotation, and the consistency and stability of the rotating operation are ensured.

[0075] The above merely describes optional embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. 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.

[0076] In addition, it should be noted that various specific technical features described in the foregoing embodiments can be combined in any appropriate manner without contradiction, and the present application will not describe various possible combinations again in order to avoid unnecessary repetition.
