[0034] Please refer to Figure 1 and Figure 2 This embodiment provides a pocket corner folding mechanism 100, including a driving member 110 and two first guide plates 120 spaced apart along the transmission direction of the conveyor belt 300. The surface of the first guide plate 120 is perpendicular to the transmission surface of the conveyor belt 300. The driving member 110 and the two first guide plates 120 are drivenly connected, and the first guide plates 120 can be driven to rotate relative to the conveyor belt 300 to be perpendicular or parallel to the transmission direction of the conveyor belt 300.

[0035] Specifically, such as Figure 1 and Figure 2As shown, the pocket corner folding mechanism 100 mainly consists of two first guide plates 120. The two first guide plates 120 are arranged on the conveyor belt 300 in a relatively rotating manner to ensure the consistency and symmetry of the pocket corner folding. The rotating arrangement design allows the first guide plates 120 to flexibly change the orientation of their surfaces to adapt to different operating stages and requirements.

[0036] When the material 400 moves along the conveyor belt 300, the surface of the first guide plate 120 is parallel to the conveying direction of the conveyor belt 300. At this time, the first guide plate 120 will not obstruct the conveying process of the material 400, and the material 400 can move smoothly along the conveyor belt 300. Moreover, it is located on opposite sides of the conveyor belt 300 and can play a certain limiting effect on the conveying process of the material 400, so as to prevent the material 400 from being displaced or deviated during the conveying process.

[0037] When the material 400 is transported along the conveyor belt 300 to the bag corner folding mechanism 100, the surface of the first guide plate 120 rotates to be perpendicular to the conveying direction of the conveyor belt 300 and is located on the top surface of the conveyor belt 300. During the rotation of the first guide plate 120, it can contact and fold the corner of the first packaged bag, so that the corner of the first packaged bag fits against the side wall of the material 400. This method not only makes the appearance of the packaged product neater and more beautiful, making it easier to put into the second packaged bag, but also enhances the stability and sealing of the packaging to a certain extent.

[0038] It should be noted that, firstly, in one possible implementation of this application, such as Figure 2 As shown, the pocket corner folding mechanism 100 also includes a rotating column 130, the extension direction of which is parallel to the transmission surface of the conveyor belt 300, and a first guide plate 120 is fixedly connected to the end of the rotating column 130; the driving member 110 can drive the first guide plate 120 to rotate along the transmission surface of the conveyor belt 300 through the rotating column 130.

[0039] Specifically, the drive component 110 is the part that provides power to the rotating column 130, and it is the power source for the pocket corner folding mechanism 100 to achieve rotational operation. The drive component 110 is driven to the rotating column 130. This drive connection can be achieved through various mechanical connection methods, such as a linkage mechanism, a coupling, or a direct connection between the cylinder rod and the rotating column 130, ensuring that the power generated by the drive component 110 can be effectively transmitted to the rotating column 130.

[0040] The end of the first guide plate 120 is fixedly connected to the rotating column 130, so that the rotation of the rotating column 130 can drive the first guide plate 120 to rotate synchronously. By fixing the end of the first guide plate 120 to the rotating column 130, it is ensured that the first guide plate 120 will not undergo relative displacement or wobbling during rotation, thus ensuring the consistency and stability of the rotation operation.

[0041] Second, such as Figure 2 As shown, in one possible embodiment of this application, a second guide plate 121 is provided on the side edge of the first guide plate 120 away from the conveyor belt 300, and the surface of the second guide plate 121 is inclined toward the side away from the conveyor belt 300.

[0042] Specifically, since the material 400 is covered by a first packaging bag, in order to facilitate the stable and rapid positioning of the material 400 at the bag corner folding mechanism 100, the second guide plate 121 is inclinedly disposed at the top edge of the first guide plate 120. Therefore, when the surface of the first guide plate 120 is parallel to the transmission direction of the conveyor belt 300, the material 400 can be more easily placed on the conveyor belt 300 during the limiting process of the first guide plate 120, preventing the corner of the first packaging bag from interfering with the first guide plate 120 during the placement process on the conveyor belt 300, and avoiding the bag corner being stuck by the first guide plate 120 or generating unnecessary friction.

[0043] The bag corner folding mechanism 100 provided in this application includes a driving member 110 and two first guide plates 120 spaced apart along the transmission direction of the conveyor belt 300. The surface of the first guide plate 120 is perpendicular to the transmission surface of the conveyor belt 300. The driving member 110 and the two first guide plates 120 are driven to rotate relative to the conveyor belt 300 to be perpendicular or parallel to the transmission direction of the conveyor belt 300. When the first guide plate 120 is parallel to the transmission direction of the conveyor belt 300, the first guide plate 120 is located on the side edge of the conveyor belt 300, so as not to obstruct the transportation of the material 400. When the first guide plate 120 rotates from parallel to perpendicular to the transmission direction of the conveyor belt 300, the corner of the first packaging bag sleeved on the outside of the material 400 can be folded by the first guide plate 120 to fit against the side wall of the material 400. During the rotation of the first guide plate 120, it can contact and fold the corner of the first packaging bag, so that the corner of the first packaging bag fits against the side wall of the material 400. The aforementioned corner folding mechanism 100 can fold the corners of the packaged bag, making it easier to insert into a second packaged bag, thereby improving packaging efficiency and aesthetics.

[0044] For example, such as Figure 3 and Figure 4As shown, the driving component 110 includes a support plate 111, a sliding plate 112, and a sliding cylinder 113. The support plate 111 is disposed at the bottom of the conveyor belt 300. There are two sliding plates 112, which are perpendicular to the conveying direction of the conveyor belt 300. There are two sliding cylinders 113, which are attached to the surface of the support plate 111 and are respectively driven to the two sliding plates 112. At least one end of the sliding plate 112 extends to the outer wall of the support plate 111 and is movably connected to the rotating column 130. The two sliding cylinders 113 respectively drive the two sliding plates 112 to move in directions that are opposite to or close to each other, thereby driving the rotating column 130 to rotate the first guide plate 120.

[0045] Specifically, such as Figure 4 As shown, the support plate 111 serves as the basic support structure for the entire drive component 110, playing a crucial role in bearing and positioning other components. Preferably, the support plate 111 can be made of a material with sufficient strength and rigidity, such as a high-strength metal plate.

[0046] Two sliding plates 112 are disposed on the support plate 111, with at least one end of each sliding plate 112 extending to the outside of the support plate 111, thereby providing space and conditions for the installation and movement of the rotating column 130. The sliding plates 112 and the rotating column 130 can be connected by a hinge, allowing the rotating column 130 to rotate relative to the sliding plates 112.

[0047] The end of the rotating column 130 furthest from the sliding plate 112 is connected to the first guide plate 120, which can transmit the movement of the sliding plate 112 to the first guide plate 120. This connection method ensures the effective transmission of rotational motion. When the sliding plate 112 moves, the first guide plate 120 can perform the corresponding rotational operation through the transmission of the rotating column 130.

[0048] The pushing mechanism includes two sliding cylinders 113, designed to independently drive the two sliding plates 112. Each cylinder is connected to one of the two sliding plates 112 to effectively transmit the linear motion power generated by the cylinders 113 to the sliding plates 112. The two cylinders 113 are positioned opposite each other to ensure that the second guide plate 121 can also be positioned opposite each other. When the two cylinders 113 move in opposite directions, the two sliding plates 112 also move in opposite directions. At this time, the rotating column 130, hinged to the sliding plate 112, rotates relative to the sliding plate 112 due to the force provided by the sliding plate 112, thereby driving the first guide plate 120 to rotate.

[0049] Optionally, such as Figure 4As shown, at least one end of the sliding plate 112 is provided with a sliding column 1121, and the end of the rotating column 130 is connected to a movable plate 131. The movable plate 131 is inclinedly provided with a sliding groove 1331. The sliding column 1121 is locked in the sliding groove 1331 and can slide along the sliding groove 1331. The sliding cylinder 113 drives the two sliding plates 112 to move in opposite directions, so that the sliding column 1121 moves along the sliding groove 1331, thereby driving the rotating column 130 to drive the first guide plate 120 to rotate.

[0050] Specifically, such as Figure 4 As shown, the rotating column 130 plays an important role in transmitting motion to the first guide plate 120 in this mechanism. A movable plate 131 is connected to the end of the rotating column 130, which is designed to cooperate with the sliding column 1121 on the sliding plate 112.

[0051] The sliding column 1121 is engaged within the sliding groove 1331. When the sliding cylinder 113 starts working, driving the two sliding plates 112 to move in opposite directions, the linear motion of the sliding plates 112, due to the engagement of the sliding column 1121 within the sliding groove 1331 of the movable plate 131, will cause the sliding column 1121 to slide along the sliding groove 1331. During the sliding of the sliding column 1121 along the inclined sliding groove 1331, a component force perpendicular to the sliding direction of the sliding column 1121 will be generated due to the inclined setting of the sliding groove 1331. This component force will act on the movable plate 131, thereby causing the rotating column 130 to rotate. Because the rotating column 130 is connected to the first guide plate 120, the rotation of the rotating column 130 will further drive the first guide plate 120 to rotate.

[0052] This ingenious motion transmission transforms the linear motion of the sliding cylinder 113 into the rotational motion of the rotating column 130, ultimately achieving precise motion transmission and control of the first guide plate 120. This ensures that the bag corner folding mechanism 100 can perform the predetermined action when folding the corner of the first packaging bag covering the material 400, thus ensuring the accuracy and reliability of the folding action.

[0053] Optionally, one end of each of the two sliding plates 112 extends to the outside of the support plate 111 to be movably connected to the rotating column 130; the two rotating columns 130 connected to the two sliding plates 112 are located on the same side of the support plate 111; or, the two rotating columns 130 connected to the two sliding plates 112 are located on opposite sides of the support plate 111; or, both opposite ends of the sliding plates 112 extend to the outside of the support plate 111 to be movably connected to the rotating column 130.

[0054] Specifically, this application does not impose any limitation on the specific number of first guide plates 120, as long as there is at least one pair of first guide plates 120 spaced apart and arranged opposite each other to reliably limit the material 400. If there is a pair of first guide plates 120, one end of each of the two sliding plates 112 extends to the outside of the support plate 111 to be movably connected to the rotating column 130, that is, there are a total of two rotating columns 130, and each rotating column 130 is connected to a first guide plate 120.

[0055] In one possible embodiment of this application, the two rotating columns 130 connected to the two sliding plates 112 are located on the same side of the support plate 111, so that the two first guide plates 120 are disposed on the same side of the conveyor belt 300; in another possible embodiment of this application, the two rotating columns 130 connected to the two sliding plates 112 are located on opposite sides of the support plate 111, so that the two first guide plates 120 are respectively disposed on both sides of the conveyor belt 300.

[0056] When there are two pairs of first guide plates 120, both ends of the sliding plate 112 extend to the outside of the support plate 111 to be movably connected with the rotating column 130. At this time, one sliding plate 112 is connected to two rotating columns 130.

[0057] Another aspect of the embodiments of this application, such as Figure 1 As shown, a bagging device 200 is provided, including a pushing assembly and a bag corner folding mechanism 100. The pushing assembly includes a pushing cylinder 211 and a push rod 212 connected by a transmission. The push rod 212 is disposed on the edge of the conveyor belt 300 and is spaced apart from the opening of the second packaging bag. The two first guide plates 120 of the bag corner folding mechanism 100 are respectively located on opposite sides of the push rod 212. After the material 400 is packaged in the first packaging bag, the bag corner folding mechanism 100 folds the corners of the first packaging bag to fit against the side wall of the material 400. Then, the pushing cylinder 211 drives the push rod 212 to move in a direction perpendicular to the transmission direction of the conveyor belt 300, so as to push the material 400 into the second packaging bag through the opening of the second packaging bag.

[0058] Specifically, this application also provides a bagging device 200, such as... Figure 1 As shown, the device consists of two main parts: a pushing component and a bag corner folding mechanism 100. These two parts work together to complete the bagging operation.

[0059] The pushing component is mainly responsible for pushing the material 400 into the second packaging bag, while the bag corner folding mechanism 100 is responsible for folding the corners of the first packaging bag 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 bagging.

[0060] The pushing assembly includes a pushing cylinder 211 and a push rod 212 connected by a transmission. The pushing cylinder 211 serves as a power source, providing the necessary power to push the push rod 212. The push rod 212 is the component that directly contacts the material 400 and pushes it into the second packaging bag. It is positioned along the edge of the conveyor belt 300, utilizing the conveying function of the conveyor belt 300 to ensure that after the material 400 is transported to the appropriate position, the push rod 212 can promptly and accurately apply a pushing force to the material 400, thus accurately pushing it into the second packaging bag. The pushing cylinder 211 drives the push rod 212 to move perpendicular to the conveying direction of the conveyor belt 300, ensuring that the material 400 is not interfered with laterally or in other directions when entering the second packaging bag, preventing jamming or positional deviation, thereby improving the accuracy and reliability of the bagging process.

[0061] Furthermore, when the surface of the first guide plate 120 is rotated to be perpendicular to the transmission direction of the conveyor belt 300, that is, parallel to the line connecting the push rod 212 and the opening of the second packaging bag, both sides of the material 400 are limited by the surface of the first guide plate 120. Therefore, when the push rod 212 pushes the material 400 toward the opening of the second packaging bag, the movement path of the material 400 can be made more precise, avoiding positional deviation of the material 400 during the pushing process, and further improving the bagging efficiency and reliability.

[0062] The aforementioned bagging device 200 can accurately insert the corners of the sealed bag into the second sealed bag after folding the corners, thereby improving the accuracy and stability of the bagging process, as well as the continuity and efficiency of the entire bagging process. The specific structure and beneficial effects of the corner folding mechanism 100 have been described in detail above and will not be repeated here.

[0063] In one possible implementation of this application, such as Figure 1 As shown and Figure 2 As shown, the bagging device 200 also includes a bag corner straightening mechanism 220. The bag corner straightening mechanism 220 includes two pairs of straightening rods 221 and two limiting plates 222. The two limiting plates 222 are arranged along the transmission direction of the conveyor belt 300 and are located on opposite sides of the conveyor belt 300. The two pairs of straightening rods 221 are respectively arranged on the side of the two limiting plates 222 away from the conveyor belt 300 and protrude vertically from the limiting plates 222. When the material 400 is placed on the conveyor belt 300, the outer wall of the straightening rod 221 contacts the first packaging bag on the outside of the material 400. The driving member 110 drives each pair of straightening rods 221 to move in opposite directions so that the opposite ends of the first packaging bag are straightened until they are parallel to the plate surface of the limiting plate 222. The limiting plate 222 is used to maintain the shape of the first packaging bag until the material 400 is transmitted along the conveyor belt 300 to the bag corner folding mechanism 100.

[0064] Specifically, such as Figure 2 As shown, the limiting plate 222 of the bag corner straightening mechanism 220 is arranged along the conveying direction of the conveyor belt 300, and the two limiting plates 222 are respectively arranged on both sides of the conveyor belt 300; the straightening rod 221 is attached to the outer wall of the limiting plate 222 and extends vertically to protrude from the top surface of the limiting plate 222, so that each side of the conveyor belt 300 has two spaced straightening rods 221. When the material 400 is placed on the conveyor belt 300, the first packaging bag on its outside can first contact the straightening rod 221 and then contact the limiting plate 222.

[0065] After the corners of the first packaged bag are straightened, it is placed between two limiting plates 222. In addition to constraining the position of the material 400, the limiting plates 222 also maintain the shape of the first packaged bag. After the straightening rod 221 straightens the corners of the packaged bag until they are parallel to the surface of the limiting plates 222, the limiting plates 222 effectively prevent the corners of the packaged bag from deforming or shifting position again. Since the limiting plates 222 are arranged along the conveyor belt 300 and located on both sides of the conveyor belt 300, they can support and limit the sides of the packaged bag, ensuring that the packaged bag maintains its straightened and regular shape throughout subsequent conveying and processing. This function of maintaining the shape of the packaged bag ensures that the shape and state of the packaged bag meet the requirements during subsequent processes, avoiding the impact of corner deformation on product packaging quality, and improving the stability and reliability of the entire packaging process.

[0066] For example, such as Figure 6 and Figure 7 As shown, the bag corner straightening mechanism 220 also includes a support plate 223 and a drive motor 224. The support plate 223 is disposed at the bottom of the conveyor belt 300; the drive motor 224 is disposed on the support plate 223 and is connected to each pair of straightening rods 221 for transmission, so as to drive each pair of straightening rods 221 to move in opposite directions.

[0067] Specifically, such as Figure 6 and Figure 7 As shown, the shape and size of the support plate 223 can be adjusted according to the specific layout of the conveyor belt 300 and the straightening rod 221. Preferably, the support plate 223 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 drive motor 224 and various forces generated during operation. In order to reduce the volume of the bag corner straightening mechanism 220 and improve space utilization, the size of the support plate 223 can be adapted to the size of the conveyor belt 300 so as to be set at the bottom of the conveyor belt 300.

[0068] The drive motor 224 converts electrical energy into mechanical energy, thereby providing the necessary power for the subsequent movement of the straightening lever 221. This application does not impose any limitations on the specific form of the drive motor 224; it can be a DC motor, an AC motor, or a stepper motor, etc.

[0069] The drive motor 224 is connected to each pair of levers 221. The specific transmission connection method can be a linkage mechanism, gear transmission, chain transmission or belt transmission, etc. This application does not impose any restrictions on this, as long as it can ensure that the rotational motion generated by the drive motor 224 is converted into linear motion of the levers 221 in mutually opposite directions.

[0070] When the drive motor 224 starts to rotate, the straightening rod 221 can move in opposite directions under the power to apply outward pulling force to both ends of the first packaging bag, stretching the originally bent or irregular bag corners to a regular state, so that both ends of the packaging bag are parallel to the plate surface of the limiting plate 222, thereby achieving the purpose of straightening the bag corners.

[0071] Optionally, such as Figure 5 As shown, the bagging device 200 also includes a material picking component 230, which is disposed on one side of the conveyor belt 300. The material picking component 230 includes a material picking gripper 231 and a material picking moving cylinder 232, which is drivenly connected to the material picking gripper 231. The material picking moving cylinder 232 can drive the material picking gripper 231 to move vertically to approach or move away from the conveyor belt 300. The material picking gripper 231 is used to pick up the material 400 covered with the first packaging bag and place it on the conveyor belt 300.

[0072] Specifically, in order to ensure that the bag corner straightening operation can be carried out in an orderly manner, the bagging device 200 also includes a material picking component 230. The setting of the material picking component 230 improves the automation level of the entire mechanism, making it easier to introduce the material 400 into the workflow of straightening and bag corner folding operations, reducing the complexity and uncertainty of manual operation, and improving production efficiency and operational continuity.

[0073] like Figure 5 As shown, the material picking component 230 is located on one side of the conveyor belt 300. It includes a material picking gripper 231 and a material picking moving cylinder 232, so as to pick up the material 400 that has been covered with the first packaging bag from other workstations through the material picking gripper 231, and place it on the conveyor belt 300 in the vertical direction for subsequent bag corner straightening and bag corner folding operations.

[0074] This operation allows material 400 to smoothly enter the transport process of conveyor belt 300, thus seamlessly connecting the material picking operation with the subsequent straightening operation, forming a complete material 400 processing flow, and improving the automation level and work efficiency of the entire mechanism.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0076] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
