Description

Technical Field

[0001] This utility model relates to the field of production line technology, specifically to a bag-feeding device and packaging equipment. Background Technology

[0002] In traditional production lines, materials (such as flat panel displays) need to be packaged before leaving the factory. During packaging, the materials need to be placed into packaging bags, which is usually done manually. However, manual bagging is time-consuming and labor-intensive, with high physical labor and consumption, and low work efficiency. Therefore, existing bagging devices are used for bagging. The bagging device includes a pushing component, which pushes the flat panel display directly into the opened packaging bag to save manpower. However, when the material is a large and heavy object such as a flat panel display, the packaging bag is thin, and the material is prone to falling into the packaging bag, causing the packaging bag to break. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a bag-inserting device is provided, the technical solution of which is as follows.

[0004] The bagging device includes a receiving and conveying assembly, a fork arm assembly, a first pushing assembly, and a second pushing assembly. The fork arm assembly is movable between a starting position and a bagging position along the material conveying path, and a transition position is also provided between the starting position and the bagging position on the material conveying path. The fork arm assembly has an infeed section and an outfeed section. The first pushing assembly is located beside the starting position to push the material onto the infeed section. The second pushing assembly is located beside the transition position to push the material located on the infeed section onto the outfeed section. The receiving and conveying assembly is located at the bagging position. When the fork arm assembly moves to the bagging position, the material located on the outfeed section enters the packaging bag located on the receiving and conveying assembly.

[0005] The bagging device of this utility model, when the fork arm assembly is in the starting position, pushes the material onto the feeding section through the first pushing component. The fork arm assembly moves from the starting position to the transition position. After reaching the transition position, the second pushing component pushes the material on the feeding section onto the discharging section. Finally, the fork arm assembly moves to the bagging position, the discharging section is located inside the packaging bag, and at least part of the second pushing component pushes the material inside the packaging bag. The receiving and conveying component supports the material entering the packaging bag as the discharging section moves towards the starting position until the material is completely supported by the receiving and conveying component after bagging. The second pushing component then moves out of the packaging bag, and the subsequent packaging steps are performed. In this way, the bagging device can automate the material bagging operation, save manpower, improve work efficiency, and prevent the packaging bag from breaking due to the material falling by supporting the material entering the packaging bag as the receiving and conveying component moves towards the starting position.

[0006] For example, the receiving and conveying assembly includes at least three receiving sections for supporting the packaging bag. The at least three receiving sections are arranged sequentially along the extension direction of the material conveying path, and each of the at least three receiving sections is connected to a lifting assembly. The at least three receiving sections and the lifting assembly are connected to a translation assembly. The at least three receiving sections and the lifting assembly are movable between a first position and a second position by the translation assembly. In the first position, the at least three receiving sections rise sequentially through the correspondingly connected lifting assemblies to support the material entering the packaging bag. In the second position, the at least three receiving sections convey the material into the bag. This setup serves two purposes. First, after the material reaches the bagging position, as the discharge section moves towards the starting position, at least three receiving sections rise sequentially via corresponding connected lifting components to stably support the material, effectively preventing the packaging bag from breaking due to material falling. Second, when the bagging device is installed on the conveyor line, after the at least three receiving sections support the material into the bag, subsequent bagging operations can be performed at the first position. After packaging is completed, at least three receiving sections move to the second position to connect with the subsequent conveying device to transport the bagged material. The subsequent conveying device and the receiving conveying components can work simultaneously, improving work efficiency.

[0007] For example, the material receiving and conveying assembly includes a first receiving section, a second receiving section, and a third receiving section. The third receiving section is farther from the starting position than the second receiving section, and the second receiving section is farther from the starting position than the first receiving section. The first receiving section is connected to a first lifting assembly, the second receiving section is connected to a second lifting assembly, and the third receiving section is connected to a third lifting assembly. The first receiving section, the second receiving section, the third receiving section, the first lifting assembly, the second lifting assembly, and the third lifting assembly are movable between a first position and a second position by a translation assembly. In the first position, the third receiving section rises sequentially via the third lifting assembly, the second receiving section via the second lifting assembly, and the first receiving section via the first lifting assembly to support the material entering the packaging bag. In the second position, the first receiving section, the second receiving section, and the third receiving section convey the material into the bag. This setup serves two purposes. First, after the material reaches the bagging position, as the discharge section moves towards the starting position, the three receiving sections rise sequentially via corresponding connected lifting components to stably support the material, effectively preventing the material's center of gravity from shifting or falling, which could lead to damage to the packaging bag. Second, when the bagging device is installed on the conveyor line, after the three receiving sections support the material into the bag, subsequent bagging operations can be performed at the first position. After packaging is completed, the three receiving sections move to the second position to connect with the subsequent conveying device to transport the bagged material. The subsequent conveying device and the receiving conveying components can work simultaneously, improving work efficiency.

[0008] For example, the fork arm assembly includes a fork arm, a first drive assembly, and a second drive assembly. The first drive assembly is connected to the fork arm to drive the fork arm to move along the material conveying path within a first stroke. The second drive assembly is connected to the first drive assembly to drive the fork arm to move along the material conveying path within a second stroke via the first drive assembly. The sum of the first stroke and the second stroke is equal to the distance between the starting position and the bagging position. This configuration reduces the burden on individual drive assemblies, extends their lifespan, and reduces the space occupied by the drive assemblies along the material conveying path. It also allows for repair of faulty parts of the fork arm, the first drive assembly, or the second drive assembly, reducing maintenance costs.

[0009] For example, the fork arm is connected to the first drive assembly via a first guide member, and the first drive assembly is connected to the second drive assembly via a second guide member. The fork arm has a first end away from the bag entry position, the first guide member has a second end away from the bag entry position, and the second guide member has a third end away from the bag entry position. When the fork arm assembly is in the starting position, the first, second, and third ends are all in the starting position. When the fork arm assembly is in the bag entry position, the first end is farther from the starting position than the second end, and the second end is farther from the starting position than the third end. This configuration ensures, on the one hand, the stability of the fork arm's movement during the first stroke through the guiding effect of the first guide member, and the stability of the first guide member and the fork arm's movement during the second stroke through the guiding effect of the second guide member. On the other hand, when the fork arm assembly is in the starting position, the first, second, and third ends are all in the starting position, facilitating precise control of the fork arm assembly to reach the starting position. When the fork arm assembly is in the bag entry position, the first end is farther from the starting position than the second end, and the second end is farther from the starting position than the third end, facilitating the positioning of the fork arm to precisely control its arrival at the bag entry position.

[0010] For example, the fork arm includes a first arm, a second arm, an anti-rotation structure, and a plurality of first rollers. The plurality of first rollers are disposed between the first arm and the second arm, and the anti-rotation structure is disposed on the first arm and / or the second arm to prevent partial rotation of the first rollers. With this configuration, when the material moves on the fork arm, the rotation of the first rollers reduces friction, facilitating material movement; at the position where the material needs to stay temporarily on the fork arm, the anti-rotation structure can prevent the first rollers from rotating, ensuring that the material can remain stably on the fork arm.

[0011] For example, the second pushing assembly includes a third driving assembly, a fourth driving assembly, and a pushing part. The third driving assembly is connected to the pushing part to drive the pushing part to move between a third position and a fourth position along the direction perpendicular to the material conveying path. The fourth driving assembly is connected to the third driving assembly to drive the pushing part to move between a transition position and a bag entry position along the extension direction of the material conveying path. With this configuration, the pushing part moves to the fourth position where it abuts the material along the direction perpendicular to the material conveying path via the third driving assembly, and the fourth driving assembly pushes the material from the infeed section of the fork arm to the discharge section, thereby enabling the material to move on the fork arm and push the material into the packaging bag.

[0012] For example, the third drive assembly is connected to the fourth drive assembly via a third guide member. The third drive assembly includes a first drive member and a second drive member. The first drive member is connected to the push member to drive the push member to move within a third stroke along the direction perpendicular to the material conveying path. The second drive member is connected to the first drive member to drive the first drive member to move the push member within a fourth stroke along the direction perpendicular to the material conveying path. The sum of the third stroke and the fourth stroke is equal to the distance between the third position and the fourth position. This configuration reduces the burden on individual drive members, extends their lifespan, and reduces the space occupied by the drive members along the direction perpendicular to the material conveying path. Simultaneously, it allows for repair of faulty parts of the first drive member, the second drive member, or the push member, reducing maintenance costs.

[0013] For example, the first pushing assembly includes a pushing section and a fifth driving assembly. The pushing section is connected to the fifth driving assembly. When the fork arm assembly is in the starting position, the fifth driving assembly drives the pushing section to push the material onto the feeding section. This configuration enables the material to be pushed onto the feeding section, and the structure is simple, saving costs.

[0014] According to another aspect of this utility model, a packaging device is provided, which includes a conveyor line and a bag-feeding device as described above, the bag-feeding device being located on the conveyor line. Since the bag-feeding device described above has the aforementioned beneficial effects, the packaging device including the bag-feeding device also has the aforementioned beneficial effects, which will not be elaborated further here.

Detailed Implementation

[0028] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0029] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0030] An embodiment of this utility model provides a bag-feeding device. The bag-feeding device provided by this utility model can be applied to packaging equipment. The following will describe in detail an embodiment of the bag-feeding device according to the accompanying drawings.

[0031] See also Figures 1 to 8The bagging device may include a receiving and conveying assembly 10, a fork arm assembly 20, a first pushing assembly 30, and a second pushing assembly 40. The fork arm assembly 20 is movable along the material conveying path between a starting position and a bagging position, and the material conveying path may also have a transition position between the starting position and the bagging position. The fork arm assembly 20 may have an infeed section 201 and an outfeed section 202. The first pushing assembly 30 may be located beside the starting position to push material onto the infeed section 201. The second pushing assembly 40 may be located beside the transition position to push material located on the infeed section 201 onto the outfeed section 202. The receiving and conveying assembly 10 may be located at the bagging position. When the fork arm assembly 20 moves to the bagging position, the material located on the outfeed section 202 can enter the packaging bag located on the receiving and conveying assembly 10.

[0032] The bagging device of this utility model, when the fork arm assembly 20 is in the starting position, pushes the material onto the feeding section 201 by the first pushing component 30. The fork arm assembly 20 moves from the starting position to the transition position. After reaching the transition position, the second pushing component 40 pushes the material on the feeding section 201 onto the discharging section 202. Finally, the fork arm assembly 20 moves to the bagging position, the discharging section 202 is located inside the packaging bag, and at least part of the second pushing component 40 pushes the material inside the packaging bag. The receiving and conveying component 10 supports the material entering the packaging bag when the discharging section 202 moves towards the starting position until the material is completely supported by the receiving and conveying component 10 after bagging. The second pushing component 40 moves out of the packaging bag, and then the subsequent packaging steps are performed. In this way, the bagging device can realize the automation of the material bagging operation, save manpower, improve work efficiency, and prevent the packaging bag from being damaged due to the material falling by supporting the material entering the packaging bag when the discharging section 202 moves towards the starting position.

[0033] See also Figures 1 to 5The receiving and conveying assembly 10 may include at least three receiving sections for supporting the packaging bag. Specifically, the number of receiving sections may be three, four, or five, etc., and the number of receiving sections is related to the center of gravity of the material. When the discharge section 202 moves towards the starting position, it ensures that the center of gravity of the material is always located on the discharge section 202 and / or the receiving sections, thereby preventing the material from falling. The receiving sections may be a second roller or a belt conveyor, etc. The second roller can reduce friction between itself and the material, and the belt conveyor can automatically convey the material after starting, avoiding the need to add other components for pushing or handling, thereby reducing space occupation and lowering costs. The at least three receiving sections may be arranged sequentially along the extension direction of the material conveying path. The at least three receiving sections may be connected to a lifting assembly. The at least three receiving sections and the lifting assembly may be connected to a translation assembly 140. The at least three receiving sections and the lifting assembly are movable between the first position and the second position by the translation assembly 140. In the first position, at least three receiving sections can be sequentially raised via correspondingly connected lifting components to support material entering the packaging bag. In the second position, at least three receiving sections can convey material into the bag. The lifting components may include a lifting rod and a lifting drive, one end of which may be connected to the lifting drive and the other end to the receiving section. The lifting drive may be a motor or cylinder, etc. The translation component 140 may include a translation push rod and a translation drive, one end of which may be connected to the translation drive and the other end to either the lifting drive or the receiving section. Thus, on the one hand, when the material reaches the bagging position and the discharge section 202 moves towards the starting position, at least three receiving sections rise sequentially through corresponding connected lifting components to stably support the material, thereby effectively avoiding the problem of the packaging bag being damaged due to the material falling; on the other hand, when the bagging device is set on the conveyor line, after the material is supported by the at least three receiving sections, subsequent bag sealing and other operations can be performed at the first position. After packaging is completed, at least three receiving sections move to the second position to connect with the subsequent conveying device to transport the bagged material. The subsequent conveying device and the receiving conveying component 10 can work simultaneously, improving work efficiency.

[0034] See also Figures 1 to 2The material receiving and conveying assembly 10 may include a first receiving section 101, a second receiving section 102, and a third receiving section 103. The third receiving section 103 is located further away from the starting position than the second receiving section 102, and the second receiving section 102 is located further away from the starting position than the first receiving section 101. The first receiving section 101 may be connected to a first lifting assembly 110. The second receiving section 102 may be connected to a second lifting assembly 120. The third receiving section 103 may be connected to a third lifting assembly 130. The first receiving section 101, the second receiving section 102, the third receiving section 103, the first lifting assembly 110, the second lifting assembly 120, and the third lifting assembly 130 are movable between a first position and a second position via a translation assembly 140. In the first position, the third receiving section 103 can be raised sequentially via the third lifting component 130, the second receiving section 102 via the second lifting component 120, and the first receiving section 101 via the first lifting component 110 to support the material entering the packaging bag. In the second position, the first receiving section 101, the second receiving section 102, and the third receiving section 103 can convey the material after it has been placed in the bag. Thus, on the one hand, after the material reaches the bag-entry position, when the discharge section 202 moves towards the starting position, the three receiving sections rise sequentially via their corresponding connected lifting components to stably support the material, thereby effectively preventing the problem of the material's center of gravity shifting and falling, which could lead to damage to the packaging bag; on the other hand, when the bag-entry device is set on the conveyor line, after the three receiving sections support the material entering the bag, subsequent bag-sealing operations can be performed in the first position. After packaging is completed, the three receiving sections move to the second position to connect with the subsequent conveying device to convey the material after it has been placed in the bag. The subsequent conveying device and the receiving conveying component 10 can work simultaneously, improving work efficiency.

[0035] See again Figure 1 and Figure 2 The receiving and conveying assembly 10 may also include a docking lifting assembly 150. When the receiving and conveying assembly 10 conveys the bagged material to the subsequent conveying device, the docking lifting assembly 150 drives each lifting assembly and each receiving section to rise and fall together to achieve docking with the subsequent conveying device in height, thus avoiding the phenomenon of material tilting and falling caused by the drop difference generated by the direct lifting of multiple lifting assemblies.

[0036] Specifically, the first receiving section 101 and the third receiving section 103 can be belt conveyors, and the second receiving section 102 can be a second roller. The first lifting assembly 110, the second lifting assembly 120, and the third lifting assembly 130 can be mounted on the first plate 161. The first lifting assembly 110 can include a first lifting rod 111 and a first lifting drive component 112, with one end of the first lifting rod 111 connected to the first lifting drive component 112 and the other end connected to the first receiving section 101. The second lifting assembly 120 can include a second lifting rod 121 and a second lifting drive component 122, with one end of the second lifting rod 121 connected to the second lifting drive component 122 and the other end connected to the second receiving section 102. The third lifting assembly 130 can include a third lifting rod 131 and a third lifting drive component 132, with one end of the third lifting rod 131 connected to the third lifting drive component 132 and the other end connected to the third receiving section 103. A first guide assembly 171 is provided between the first plate 161 and the first receiving section 101, the second receiving section 102, and the third receiving section 103, respectively, to ensure that the first receiving section 101, the second receiving section 102, and the third receiving section 103 can move stably relative to the first plate 161. The first guide assembly 171 can be multiple guide posts, with a simple structure and easy manufacturing. A second plate 162 is provided below the first plate 161, and a docking lifting assembly 150 can be provided on the second plate 162. The docking lifting assembly 150 can include a lifting rod 151 and a docking lifting drive component 152. One end of the lifting rod 151 can be connected to the docking lifting drive component 152, and the other end can be connected to the first plate 161. A second guide assembly 172 is provided between the first plate 161 and the second plate 162 to ensure that the first plate 161 can move stably relative to the second plate 162. The second guide assembly 172 can be multiple guide posts, with a simple structure and easy manufacturing. The second plate 162 can be connected to the translation push rod via the third guide component 173. The third guide component 173 can be a slide rail and a slider. The slider can drive the translation push rod through the translation drive component to slide relative to the slide rail, and the second plate 162 can be connected to the slider. Of course, the first guide component 171, the second guide component 172, and the third guide component 173 can also be other structures with guiding functions to suit various scenarios. In this way, on the one hand, after the material reaches the bagging position, when the discharge section 202 moves towards the starting position, the three receiving sections rise sequentially through the corresponding connected lifting components to stably support the material, thereby effectively avoiding the problem of the material's center of gravity shifting and falling, causing the packaging bag to break. On the other hand, when the bagging device is set on the conveyor line, after the three receiving sections support the material into the bag, subsequent bagging and other operations can be performed at the first position. After packaging is completed, the three receiving sections move to the second position to dock with the subsequent conveying device to transport the bagged material. The subsequent conveying device and the receiving conveying component 10 can work simultaneously, improving work efficiency.

[0037] See also Figures 3 to 5 The fork arm assembly 20 may include a fork arm 210, a first drive assembly 220, and a second drive assembly 230. The first drive assembly 220 may be connected to the fork arm 210 to drive the fork arm 210 to move along the material conveying path within a first stroke. The second drive assembly 230 may be connected to the first drive assembly 220 to drive the fork arm 210 to move along the material conveying path within a second stroke via the first drive assembly 220. The sum of the first stroke and the second stroke is equal to the distance between the starting position and the bagging position. It should be noted that the first stroke can be the distance between the starting position and the transition position, and the second stroke can be the distance between the transition position and the bagging position. Specifically, the first drive assembly 220 may include a first driver and a first rod, one end of which may be connected to the first driver and the other end of which may be connected to the fork arm 210. The second drive assembly 230 may include a second driver and a second rod, one end of which may be connected to the second driver and the other end of which may be connected to the first driver. This reduces the burden on individual drive components, extends their lifespan, and reduces the space occupied by the drive components along the material conveying path. At the same time, it allows for the repair of faulty parts of the fork arm 210, the first drive component 220, or the second drive component 230, thus reducing maintenance costs.

[0038] See again Figures 2 to 5The fork arm 210 can be connected to the first drive assembly 220 via the first guide member 240. The first drive assembly 220 can be connected to the second drive assembly 230 via the second guide member 250. Specifically, both the first guide member 240 and the second guide member 250 can be guide rails to ensure that the fork arm 210 can move stably along the extension direction of the material conveying path. Of course, the first guide member 240 and the second guide member 250 can also be other structures with guiding functions to suit various scenarios. Understandably, the feeding section 201 and the discharging section 202 are provided on the fork arm 210. The fork arm 210 may have a first end 211 away from the bag-feeding position, the first guide member 240 may have a second end 241 away from the bag-feeding position, and the second guide member 250 may have a third end 251 away from the bag-feeding position. When the fork arm assembly 20 is in the starting position, the first end 211, the second end 241, and the third end 251 can all be in the starting position, that is, the first end 211, the second end 241, and the third end 251 are aligned. When the fork arm assembly 20 is in the bag-entry position, the first end 211 can be farther away from the starting position than the second end 241, and the second end 241 can be farther away from the starting position than the third end 251. It should be noted that when the fork arm assembly 20 is in the bag-entry position, the first guide 240 and the second guide 250 can be farther away from the receiving conveyor assembly 10 than the discharge section 202, so as to ensure that the discharge section 202 is positioned to enter the packaging bag and is above the receiving conveyor assembly 10, avoiding interference from the first guide 240 and the second guide 250 when the discharge section 202 cooperates with the receiving conveyor assembly 10. Thus, on the one hand, the guiding effect of the first guide member 240 ensures the stability of the fork arm 210 during the first stroke, and the guiding effect of the second guide member 250 ensures the stability of the first guide member 240 and the fork arm 210 during the second stroke; on the other hand, when the fork arm assembly 20 is in the starting position, the first end 211, the second end 241 and the third end 251 are all in the starting position, which facilitates precise control of the fork arm assembly 20 to reach the starting position. When the fork arm assembly 20 is in the bag-filling position, the first end 211 is farther away from the starting position than the second end 241, and the second end 241 is farther away from the starting position than the third end 251, which facilitates positioning the fork arm 210 so as to precisely control the fork arm 210 to reach the bag-filling position.

[0039] See Figure 4 A first sensor 260 can be provided at the end of the fork arm assembly 20 near the starting position. The first sensor 260 can detect whether the first end 211, the second end 241, and the third end 251 have accurately reached the starting position. In this way, it can ensure that the fork arm assembly 20 is accurately reset to the starting position, preventing the material from being pushed due to inaccurate positioning, which could lead to material deviation or damage.

[0040] See Figure 5The fork arm 210 may include a first arm 212, a second arm 213, an anti-rotation structure 215, and multiple first rollers 214. The multiple first rollers 214 may be disposed between the first arm 212 and the second arm 213. The anti-rotation structure 215 may be disposed on the first arm 212 and / or the second arm 213 to prevent partial rotation of the first rollers 214. Specifically, the first rollers 214 located in the feed section 201 and the discharge section 202 may be provided with the anti-rotation structure 215 to prevent material from falling due to inertia when the fork arm 210 transitions from a moving state to a stationary state. The anti-rotation structure 215 may consist of at least two anti-rotation blocks, which clamp the first rollers 214 to prevent rotation. Thus, when the material moves on the fork arm 210, the rotation of the first roller 214 reduces friction and facilitates material movement; the anti-rotation structure 215 can prevent the first roller 214 from rotating at the position where the material needs to stay on the fork arm 210, ensuring that the material can stay stably on the fork arm 210.

[0041] See again Figure 5 On the feeding section 201 and the discharging section 202, rollers 216 can be arranged opposite to each other between the first arm 212 and the second arm 213. The rollers 216 can be prevented from rotating by the anti-rotation structure 215. In this way, other devices near the fork arm assembly 20 can pass through the clearance space between the rollers 216 of the first arm 212 and the rollers 216 of the second arm 213, avoiding interference during operation.

[0042] See Figure 8 The second pushing assembly 40 may include a third drive assembly 410, a fourth drive assembly 420, and a pushing part 430. The third drive assembly 410 may be connected to the pushing part 430 to drive the pushing part 430 to move between a third position and a fourth position along the direction perpendicular to the material conveying path. The fourth drive assembly 420 may be connected to the third drive assembly 410 to drive the pushing part 430 to move between a transition position and a bag entry position along the extension direction of the material conveying path. In this way, the pushing part 430 moves to the fourth position where it abuts the material along the direction perpendicular to the material conveying path via the third drive assembly 410, and the fourth drive assembly 420 can push the material from the feeding section 201 of the fork arm 210 to the discharging section 202, thereby realizing the movement of the material on the fork arm 210 and pushing the material into the packaging bag.

[0043] See again Figure 8The third drive assembly 410 can be connected to the fourth drive assembly 420 via the third guide member 440. The third drive assembly 410 may include a first drive member 411 and a second drive member 412. The first drive member 411 can be connected to the pushing part 430 to drive the pushing part 430 to move within a third stroke along the direction perpendicular to the material conveying path. The second drive member 412 can be connected to the first drive member 411 to drive the first drive member 411 to move the pushing part 430 within a fourth stroke along the direction perpendicular to the material conveying path. The sum of the third stroke and the fourth stroke is equal to the distance between the third position and the fourth position. Specifically, the third guide member 440 can be a guide rail and a slider. The fourth drive assembly 420 may include a fourth drive member and a drive rod, one end of which can be connected to the fourth drive member, and the other end of which can be connected to the slider. The second drive member 412 can be connected to the slider. A fourth guide 450 may be provided between the second driving member 412 and the first driving member 411. The fourth guide 450 may be a guide rail and a slider. The third driving assembly 410 may also include a rod, one end of which may be connected to the second driving member 412 and the other end to the slider. The first driving member 411 may be connected to the slider. The first driving member 411, the second driving member 412, and the fourth driving member may be a motor or a cylinder, etc. Of course, the third guide 440 and the fourth guide 450 may also be other structures with guiding functions to suit various scenarios. In an embodiment not shown in the figure, the third driving assembly 410 may also include multiple driving members. The pushing part abuts against the material through multiple drives of the multiple driving members, so as to adapt to scenarios where the second pushing assembly 40 occupies a small space perpendicular to the material conveying path direction. In this way, the burden on individual drive components is reduced, the lifespan of drive components is extended, and the space occupied by drive components along the vertical material conveying path is reduced. At the same time, faulty parts of the first drive component 411, the second drive component 412, or the push part 430 can be repaired, reducing maintenance costs.

[0044] See also Figure 6 and Figure 7The first pushing assembly 30 may include a pushing section 310 and a fifth drive assembly 320. The pushing section 310 may be connected to the fifth drive assembly 320. When the fork arm assembly 20 is in the starting position, the fifth drive assembly 320 may drive the pushing section 310 to push the material onto the feeding section 201. Specifically, the pushing section 310 may be a plate-like component, which may be perpendicular to the platform used for feeding to increase the contact area between the pushing section 310 and the material, thereby improving the stability of the pushing. The fifth drive assembly 320 may be a motor or cylinder, etc. The pushing section 310 may be connected to the fifth drive assembly 320 via a fifth guide 330, and the pushing section 310 may move along the fifth guide 330. The fifth guide 330 may be a guide rail. Of course, the fifth guide 330 may also be other structures with guiding functions to suit various scenarios. In this way, it is possible to push the material onto the feeding section 201, and the structure is simple and cost-effective.

[0045] See again Figure 6 and Figure 7 The first feeding component 30 can be equipped with a second sensor 340 on the platform used for feeding, which is used to sense whether the material has been completely pushed onto the feeding section 201. This ensures the accuracy of feeding and avoids the phenomenon of material falling when the fork arm component 20 moves due to incomplete feeding.

[0046] The following details the working process of the bag-feeding device, in conjunction with reference to... Figures 1 to 8After the material reaches the position of the first pushing component 30, the pushing part 310 is driven by the fifth driving component 320 to push the material onto the infeed section 201 located at the starting position. After completing the pushing, the pushing part 310 returns to its original position. The fork arm 210 moves to the transition position along the extension direction of the material conveying path via the first driving component 220. The pushing part 430 moves a third stroke along the vertical material conveying direction via the first driving member 411. The second driving member 412 drives the first driving member 411 to drive the pushing part to move a fourth stroke along the vertical material conveying direction, and the pushing part abuts against the material. The fourth driving component 420 drives the second driving member 412 to drive the first driving member 411 and the pushing part 430 to move along the extension direction of the material conveying path, thereby pushing the material from the infeed section 201 to the discharge section 202. Then, the second drive assembly 230 drives the first drive assembly 220 to move the fork arm 210 along the extension direction of the material conveying path to the bag-in position. At the same time, the pushing part 430 moves to the feeding position through the fourth drive assembly 420 and continuously abuts against the material. The receiving conveying assembly 10 moves to the first position, located below the discharge section 202. After the discharge section 202 moves a distance towards the starting position, the third receiving section 103, which is furthest from the starting position, rises through the third lifting assembly 130 to receive the material after it is bagged. After the discharge section 202 continues to move a distance towards the starting position, the second receiving section 102 rises through the second lifting assembly 120 to receive the material after it is bagged. Finally, the discharge section 202 moves a distance towards the starting position again to allow the material to detach from the discharge section 202. The first receiving section 101 rises through the first lifting assembly 110 to allow the receiving conveying assembly 10 to completely receive the material after it is bagged. The pushing part 430 separates from the material, and the fork arm assembly 20 and the second pushing assembly 40 return to their original positions. After the material is bagged and sealed, the translation component 140 drives the docking lifting component 150, which in turn moves the lifting components and receiving sections to transport the bagged material to a second position. The docking lifting component 150 then drives the lifting components to connect the receiving sections with subsequent conveying devices, allowing the bagged material to continue its subsequent operations. When the bagging device is installed on a conveyor line, the above process can be repeated.

[0047] According to another aspect of this utility model, a packaging device is provided, which includes a conveyor line and a bag-feeding device as described above, the bag-feeding device being located on the conveyor line.
