Description

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In automated material packaging equipment such as bagging machines, the ability of the transfer device to efficiently and reliably transfer the filled bags from the filling station to the sealing station for sealing is one of the key factors affecting overall packaging efficiency.

[0004] Currently, most common transfer devices employ a clamping structure to secure packaging bags. These devices typically include a horizontal moving mechanism and a clamping mechanism mounted on it. The horizontal moving mechanism enables the horizontal, linear transport of the clamping mechanism and the packaging bag; the clamping mechanism, responsible for holding and securing the packaging bag, generally consists of two clamping components arranged along the width of the bag. Each clamping component includes two jaws arranged opposite each other along the thickness of the bag. During clamping, the two jaws from one clamping component work together to secure the bag across its width, thus achieving stable fixation. The bag is then transported to the sealing device via the horizontal moving mechanism to complete subsequent operations.

[0005] However, existing clamping mechanisms typically require each clamp to be equipped with an independent drive source (such as a cylinder) to achieve the opening and closing action of the grippers, resulting in a complex overall structure and high manufacturing cost. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a packaging bag transfer device, so as to overcome the technical problems of complex overall structure and high manufacturing cost of the existing transfer device, which requires each gripper to be equipped with an independent drive source.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this utility model may have fewer components, have other components not shown in the drawings, different components, components with different arrangements, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0022] An embodiment of this utility model provides a packaging bag transfer device, which can be applied to automated material packaging equipment such as bagging machines. It is mainly used to transfer packaging bags filled with materials from the filling station to the sealing station so as to facilitate the subsequent sealing of the packaging bags.

[0023] Figure 1 A schematic diagram illustrating the structure of the packaging bag transfer device provided in an embodiment of this utility model is shown. Figure 1 As shown, according to an embodiment of the present invention, the packaging bag transfer device may include a horizontal moving mechanism 10 and a clamping mechanism 20.

[0024] The horizontal moving mechanism 10 is adapted to output reciprocating linear motion along a predetermined direction to drive the clamping mechanism 20 to reciprocate along the predetermined direction. The predetermined direction mentioned in this embodiment can be understood as the direction from the filling station to the sealing station, generally a horizontal direction, specifically the length direction of the packaging bag. The horizontal moving mechanism 10 can drive the clamping mechanism 20, and even the packaging bag clamped and fixed by the clamping mechanism 20, to move from the filling station to the sealing station. The structure of the horizontal moving mechanism 10 will be described in detail below.

[0025] The single clamping mechanism 20 is mainly used to clamp and fix a single packaging bag. It is worth noting that in actual implementation, the number of clamping mechanisms 20 can be set according to needs, so that the packaging bag transfer device can transfer more packaging bags at a time. Exemplarily, the appendix of this utility model... Figure 1 The example shown illustrates a configuration with three clamping mechanisms 20. Of course, the number of clamping mechanisms 20 is not limited to this, and is not specified here.

[0026] Each clamping mechanism 20 may include two clamping components 21 disposed opposite each other along the width direction of the packaging bag. Each clamping component 21 is adapted to clamp one side of the packaging bag in its width direction.

[0027] Figure 2 The schematic diagram illustrates the structure of the clamping assembly 21 provided in this embodiment of the present invention. Figure 3 for Figure 2 The diagram shows a cross-sectional view of the clamping assembly 21. According to an embodiment of the present invention, the clamping assembly 21 may include a mounting bracket 211, two grippers 212, a gear 213, two transmission components 214, and a driver 215.

[0028] Mounting bracket 211 is mainly used to provide a carrier for mounting components such as gear 213 and drive 215, and to connect to the power output end of horizontal moving mechanism 10, so that clamping assembly 21 can move under the drive of horizontal moving mechanism 10. Two grippers 212 are arranged opposite each other along the thickness direction of the packaging bag, so as to clamp or release the packaging bag by opening and closing the two grippers 212.

[0029] Gear 213 is rotatably mounted on mounting bracket 211, with its axis parallel to the width direction of the packaging bag. Two transmission components 214 are symmetrically arranged on both sides of gear 213. Each transmission component 214 is provided with teeth 2141 that mesh with gear 213, and the teeth 2141 on each transmission component 214 extend along the arrangement direction of the two grippers 212 (i.e., the thickness direction of the packaging bag). For example, the transmission component 214 can be a cylindrical rack with a circular cross-section. Furthermore, the two transmission components 214 are respectively connected to the two grippers 212.

[0030] The driver 215 can be fixedly mounted at the bottom of the mounting bracket 211 and is adapted to output reciprocating linear motion along the arrangement direction of the two grippers 212. The power output end of the driver 215 is connected to one of the transmission components 214 to drive the transmission component 214 to reciprocate along the arrangement direction of the two grippers 212.

[0031] Based on the above configuration, when the clamping assembly 21 needs to clamp the side of the packaging bag in its width direction, the driver 215 drives the transmission component 214 connected to it to make linear motion, so that the gripper 212 on the transmission component 214 approaches the packaging bag; during this process, the transmission component 214 connected to the driver 215 forces the gear 213 to rotate through its teeth 2141. While the gear 213 rotates, it drives another transmission component 214 to make linear motion in the opposite direction, so that the gripper 212 on the transmission component 214 also approaches the packaging bag, thereby clamping the packaging bag by the two grippers 212 approaching each other; conversely, it is only necessary to drive the transmission component 214 connected to it to make linear motion in the opposite direction by the driver 215, so that the two grippers 212 move away from each other to release the packaging bag.

[0032] According to an embodiment of this utility model, by employing a single driver 215 in conjunction with a gear and rack mechanism, the design of configuring an independent driver 215 for each gripper 212 can be replaced to achieve the opening and closing of the two grippers 212. This simplifies the structure of the clamping mechanism 20 and reduces its manufacturing cost and maintenance complexity. Furthermore, the gear and rack mechanism design helps ensure that the two grippers 212 perform perfectly synchronized and opposite-direction precise movements, thereby avoiding problems such as packaging bag deformation, material spillage, or positional displacement caused by asynchronous clamping, and greatly improving the reliability and stability of the clamping action.

[0033] In some possible embodiments, refer to Figure 2 As shown, anti-slip structures such as anti-slip textures and anti-slip teeth can be provided on the opposite side of the two grippers 212 to increase the friction between the grippers 212 and the packaging bag and improve the gripping effect.

[0034] In some possible embodiments, refer to Figure 3 As shown, a receiving cavity can be provided inside the mounting bracket 211, and the gear 213 can be disposed within the receiving cavity. The receiving cavity provides reliable protection for the gear 213, thereby helping to extend the service life of the clamping assembly 21 and improve the safety of the clamping assembly 21 during operation.

[0035] In some possible embodiments, reference continues to be made to Figure 3 As shown, the mounting bracket 211 can also be provided with guide channels 216 corresponding to each transmission component 214. The guide channels 216 extend along the arrangement direction of the two grippers 212. Each transmission component 214 is slidably connected within its corresponding guide channel 216. By configuring a dedicated guide channel 216 for each transmission component 214, precise guidance can be provided for the linear motion of the transmission component 214, and reliable assurance can be provided for maintaining the meshing state between the gear 213 and the teeth 2141.

[0036] In some possible embodiments, refer to Figure 2 or Figure 3 As shown, one of the transmission components 214 may also be provided with a connecting portion 217 that connects to the corresponding gripper 212. The other transmission component 214 passes through the connecting portion 217 and slides in cooperation with it. This design enables the two transmission components 214 to have a self-guiding function. This method of providing sliding support for the other transmission component 214 through the connecting portion 217 on one transmission component 214 allows the two transmission components 214 to restrain each other, thereby effectively improving the smoothness of the movement of each transmission component 214.

[0037] In some possible embodiments, combined Figure 1 and Figure 4 As shown, the horizontal moving mechanism 10 may include a horizontal moving unit 11 and a rotating member 12. The horizontal moving unit 11 is mainly used to output reciprocating motion along the predetermined direction described above. The rotating member 12 is disposed at the power output end of the horizontal moving unit 11, enabling it to move along the predetermined direction under the drive of the horizontal moving unit 11. Furthermore, the rotating member 12 can rotate about its own axis, which is parallel to the width direction of the packaging bag. A clamping mechanism 20 is disposed on the rotating member 12.

[0038] Based on the above configuration, the horizontal moving unit 11 drives the rotating component 12 and its clamping mechanism 20 to move synchronously. Since the rotating component 12 is rotatable, the posture of the clamping mechanism 20 can be adjusted by rotating the rotating component 12. This design allows the posture of the packaging bag held by the clamping mechanism 20 to be adjusted according to actual needs, so that the bag opening can enter the sealing device at the sealing station more accurately, thereby improving the success rate and quality of sealing operations. At the same time, it allows the packaging bag transfer device to be adapted to various sealing devices with different entry directions, improving the versatility of the packaging bag transfer device.

[0039] Specifically, the rotating member 12 can be rotated around its own axis by arranging a rotation drive motor 13 at one end of the rotating member 12.

[0040] In some possible embodiments, combined Figure 4 As shown, the horizontal moving mechanism 10 may further include a spacing adjustment unit 14. The spacing adjustment unit 14 is disposed on the rotating member 12 and configured to drive the two clamping components 21 of the clamping mechanism 20 to move closer or further apart. It is understood that by providing the spacing adjustment unit 14 to adjust the spacing between the two clamping components 21 of the clamping mechanism 20, the clamping mechanism 20 is adapted to clamp packaging bags of various widths, further improving the versatility of the packaging bag transfer device.

[0041] Furthermore, the spacing adjustment unit 14 can be constructed, but is not limited to, in the manner described below.

[0042] Specifically, such as Figure 4 As shown, the spacing adjustment unit 14 may include a first belt drive mechanism 141 disposed on the rotating member 12. The first belt drive mechanism 141 includes a first drive belt 1411 extending along the width direction of the packaging bag. The first drive belt 1411 is adapted to operate under the drive of the spacing adjustment motor 142. Two clamping components 21 of the clamping mechanism 20 are respectively fixedly connected to two sides of the first drive belt 1411; specifically, mounting brackets 211 of the two clamping components 21 may be respectively fixedly connected to two sides of the first drive belt 1411.

[0043] This configuration is based on the fact that in existing belt drive mechanisms, the two sides of the drive belt move in opposite directions during operation. Therefore, when the first drive belt 1411 is driven by the pitch adjustment motor 142, the two clamping components 21 of the clamping mechanism 20 will move closer or further apart to adjust the pitch. This scheme, which utilizes the inherent reverse motion characteristics of the two sides of the drive belt to achieve pitch adjustment, can reliably drive the two clamping components 21 to complete precise synchronous opposite or forward motion, resulting in a smooth transmission process and low cost.

[0044] Furthermore, continue to refer to Figure 4 As shown, the spacing adjustment unit 14 may further include a first guide rail 143. The first guide rail 143 is disposed on the rotating member 12 and extends along the width direction of the packaging bag. Each clamping component 21 is slidably connected to the first guide rail 143, specifically, the mounting bracket 211 of each clamping component 21 may be slidably connected to the first guide rail 143.

[0045] The first guide rail 143 provides reliable support and guidance for each clamping component 21, further enhancing the stability of each clamping component 21 when it moves under the drive of the first transmission belt 1411.

[0046] In some possible embodiments, combined Figure 4 As shown, the horizontal movement unit 11 may include two opposing second belt drive mechanisms 111 and a horizontal drive component 112. Each second belt drive mechanism 111 includes a second drive belt 1111 extending in a predetermined direction. The rotating component 12 is connected to one side of the second drive belt 1111 of each of the two second belt drive mechanisms 111 on both sides in the width direction of the packaging bag.

[0047] The horizontal drive component 112 is configured to drive the second drive belts 1111 of the two second belt drive mechanisms 111 to operate synchronously. The horizontal drive component 112 may include a horizontal drive motor 1121 and a horizontal drive shaft 1122. The method of simultaneously connecting the two second belt drive mechanisms 111 to the horizontal drive motor 1121 of the horizontal drive component 112 is prior art and will not be elaborated upon here.

[0048] With this configuration, when the second transmission belts 1111 of the two second belt drive mechanisms 111 are running synchronously, the rotating component 12 can be driven to move in a predetermined direction. This scheme, which uses two second belt drive mechanisms 111 to drive the rotating component 12 synchronously on both sides, helps to eliminate the overturning moment of the rotating component 12 caused by the offset of the load center of gravity, thereby fundamentally avoiding adverse phenomena such as running jamming of the rotating component 12 and effectively improving the stability of the rotating component 12 during operation.

[0049] Furthermore, referring to Figure 4 As shown, the horizontal moving unit 11 may further include two second guide rails 113 arranged opposite each other along the width direction of the packaging bag. Each second guide rail 113 extends in a predetermined direction. The rotating member 12 is slidably connected to the two second guide rails 113 on both sides in the width direction of the packaging bag.

[0050] The second guide rail 113 provides reliable support and guidance for the rotating component 12, further enhancing the stability of the rotating component 12 when it moves under the drive of the two second transmission belts 1111.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
