Description

Technical Field

[0001] This utility model relates to a box-loading device, and more particularly to a soft packaging bag box-loading device, belonging to the field of box-loading machine technology. Background Technology

[0002] A case packer is a device used to automatically or semi-automatically pack unpackaged or small-packaged products into transport packaging (such as corrugated cardboard boxes, plastic boxes, etc.). Its main functions include automatic packing, sealing, and strapping.

[0003] The flexible packaging bag loading device in a case packing machine is a device that automatically picks up flexible packaging bags (such as plastic bags, aluminum foil bags, etc.) and places them into designated boxes. It integrates technologies from multiple fields such as mechanics, electronics, and control, achieving fully automated operation and greatly improving production efficiency.

[0004] A typical flexible packaging bag loading device consists of two parts: a loading mechanism and a box-opening mechanism. During operation, the box-opening mechanism first opens the carton's opening, allowing the flexible packaging bag to be smoothly and unobstructedly placed inside. After opening, the loading mechanism pushes the flexible packaging bag into the carton. However, existing flexible packaging bag loading devices are structurally complex and lack integration due to their design, resulting in a large footprint and high manufacturing costs.

[0005] In summary, designing a new type of flexible packaging bag box-loading device that can improve the integration of the box-loading mechanism and the box-supporting mechanism, simplify the overall structure of the flexible packaging bag box-loading device, reduce the volume space occupied, and lower the manufacturing cost are urgent technical problems that need to be solved. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the deficiencies in the existing technology by providing a flexible packaging bag box-loading device, which improves the integration of the box-loading mechanism and the box-supporting mechanism, simplifies the structure of the entire flexible packaging bag box-loading device, reduces the volume space occupied, and lowers the manufacturing cost.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a soft packaging bag box-filling device, including a box-filling mechanism and a box-supporting mechanism disposed on one side of the box-filling mechanism. The box-filling mechanism includes a first fixed side baffle and a second fixed side baffle, which are disposed opposite to each other. A lifting and lowering receiving plate is also disposed between the first fixed side baffle and the second fixed side baffle. A box-filling drive mechanism with a pushing plate is also disposed on one side of the first fixed side baffle and the second fixed side baffle. The box-supporting mechanism includes a door frame plate and a box-supporting plate rotatably connected to one side of the door frame plate. The box-supporting plate includes multiple linked box-supporting plates and one independent box-supporting plate. The support plates include multiple linked support plates, namely support plate one, support plate three, and support plate four, and independent support plates, namely support plate two. Support plates one and two are arranged opposite to each other, and support plates three and four are arranged opposite to each other. Support plates one, three, and four are all connected to support plate drive mechanism one. Under the action of support plate drive mechanism one, support plates one, three, and four can be driven to open or close. Support plate two is connected to support plate drive mechanism two. Under the action of support plate drive mechanism two, support plate two can be driven to rotate. Support plate two is located on the other side of fixed side baffle one and fixed side baffle two.

[0008] When the second support plate rotates to a position parallel to the pusher plate, the second support plate, the first fixed side baffle, the pusher plate, the second fixed side baffle, and the receiving plate enclose and form a receiving bin with an open top. When the second support plate rotates to a position opposite to the first support plate, the first to fourth support plates enclose and form a rectangular support structure.

[0009] Preferably, the support plate driving mechanism includes a support plate protrusion with an inclined groove on each of the linked support plates and a support plate cylinder on one side of the door frame plate. Each support plate protrusion has a support plate moving shaft in the inclined groove. The support plate moving shaft passes through the inclined groove and is slidably connected to the inclined groove. Multiple support plate moving shafts are connected into an integral structure. The piston rod of the support plate cylinder is connected to the support plate moving shaft of the integral structure. Under the drive of the support plate cylinder, the support plate moving shaft of the integral structure can move back and forth in the horizontal direction, thereby using the cooperation between the support plate moving shaft and the inclined groove to drive multiple linked support plates to open or close.

[0010] Preferably, a roller is fitted onto the moving shaft of the support plate passing through the inclined groove, and the roller is slidably connected to the inner circumferential surface of the inclined groove, thereby making the moving shaft of the support plate slidably connected to the inclined groove.

[0011] Preferably, a sliding groove is also provided on the inner circumferential surface of the inclined groove, and the roller slides back and forth along the sliding groove, so that the moving shaft of the support plate is slidably connected with the inclined groove.

[0012] Preferably, the second support plate is provided with a second support plate pivot, and a second pivot bearing seat is provided on the door frame plate. The second support plate pivot and the second pivot bearing seat are connected to each other, so that the second support plate is rotatably connected to one side of the door frame plate.

[0013] The second support plate driving mechanism includes a second support cylinder mounted on the door frame plate. A rack is connected to the piston rod of the second support cylinder, and a gear is mounted at one end of the second support plate rotating shaft. The rack and gear are driven together to drive one end of the second support plate to rotate around the second support plate rotating shaft when the second support cylinder is in motion.

[0014] Preferably, the box-entry driving mechanism further includes a box-entry device pushing linear mechanism and a pushing rod connected to the box-entry device pushing linear mechanism. The pushing plate is disposed on the pushing rod and can be driven to move back and forth in the horizontal direction under the push of the box-entry device pushing linear mechanism.

[0015] Preferably, the receiving plate is connected to the receiving linear mechanism of the box-entry device, and the receiving plate can move vertically up and down under the drive of the receiving linear mechanism of the box-entry device.

[0016] The beneficial effects of this utility model are as follows: By designing a rotatable support plate II between the box-infeeding mechanism and the box-supporting mechanism, this utility model makes the support plate II a shared component of both mechanisms. During material receiving, the support plate II forms a receiving compartment with other components of the box-infeeding mechanism. During box-supporting, the support plate II forms a box-supporting structure with other components of the box-supporting mechanism. Furthermore, when the support plate II rotates to become the box-supporting structure, it simultaneously forms a pushing channel, facilitating the pusher plate of the box-infeeding mechanism to smoothly push a stack of products into the carton along the pushing channel. Thus, this utility model cleverly integrates the support plate II with the box-infeeding mechanism through structural design, greatly improving the integration level of the box-infeeding and box-supporting mechanisms, simplifying the structure of the entire flexible packaging bag box-infeeding device, reducing the occupied volume space, and lowering manufacturing costs. By setting a support plate moving shaft and inclined groove cooperation structure to drive multiple support plates into open or retracted states, the carton is opened. Its overall structure is simple, compact, and has low manufacturing costs. By connecting the moving shafts of the support plates into one unit, a linkage structure of multiple support plates is realized, thereby further simplifying the device structure.

[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example: Figures 1 to 4 As shown, a soft packaging bag boxing device includes a boxing mechanism 1 and a boxing support mechanism 2 disposed on one side of the boxing mechanism 1. The boxing mechanism 1 includes a first fixed side baffle 111 and a second fixed side baffle 112. The first fixed side baffle 111 and the second fixed side baffle 112 are both connected to a frame (not shown in the figure). The first fixed side baffle 111 and the second fixed side baffle 112 are arranged opposite to each other. A lifting receiving plate (not shown in the figure) is also disposed between the first fixed side baffle 111 and the second fixed side baffle 112. A boxing drive mechanism 3 with a pusher plate 311 is also disposed on one side of the first fixed side baffle 111 and the second fixed side baffle 112.

[0031] The box-supporting mechanism 2 includes a door frame plate 211 and a box-supporting plate rotatably connected to one side of the door frame plate 211. The box-supporting plate includes multiple linked box-supporting plates and one independent box-supporting plate. The multiple linked box-supporting plates include a first box-supporting plate 212, a third box-supporting plate 213, and a fourth box-supporting plate 214. The independent box-supporting plate includes a second box-supporting plate 215. The first box-supporting plate 212 and the second box-supporting plate 215 are arranged opposite each other, and the third box-supporting plate 213 and the fourth box-supporting plate 214 are arranged opposite each other. The first box-supporting plate 212, the second box-supporting plate 215, the third box-supporting plate 213, and the fourth box-supporting plate 214 can... A rectangular support box structure is formed by enclosing the support box. The support box plate 1 212, support box plate 3 213 and support box plate 4 214 are all connected to the support box plate driving mechanism 1. Under the action of the support box plate driving mechanism 1, the support box plate 1 212, support box plate 3 213 and support box plate 4 214 can be driven to open or close. The support box plate 2 215 is connected to the support box plate driving mechanism 2. Under the action of the support box plate driving mechanism 2, the support box plate 2 215 can be driven to rotate. The support box plate 2 215 is located on the other side of the fixed side baffle 1 111 and the fixed side baffle 2 112.

[0032] When receiving materials for flexible packaging bag products, such as Figures 4 to 6 As shown, when the second box-mounted drive mechanism drives the second box-mounted plate 215 to rotate until it is parallel to the pusher plate 311, the second box-mounted plate 215, the first fixed side baffle 111, the pusher plate 311, and the second fixed side baffle 112 sequentially form a rectangular wall structure. The receiving plate 4 is then located at the bottom of the rectangular wall structure, thus forming a receiving bin with an open top between the receiving plate 4 and the rectangular wall structure. At this time, multiple soft packaging bags and foam boards fall sequentially from the top of the receiving bin onto the receiving plate 4 (e.g., ...). Figure 6 (As shown by the arrow in the image), forming a stack of products; after receiving the materials, as... Figure 7and Figure 8 As shown, the second box-plate driving mechanism drives the second box-plate 215 to rotate in the opposite direction to the position opposite to the first box-plate 212. At this time, the first box-plate 212, the second box-plate 215, the third box-plate 213, and the fourth box-plate 214 form a rectangular box-plate structure. The opening end of the carton 4 is then fitted onto the outer position. The first box-plate driving mechanism drives the first box-plate 212, the third box-plate 213, and the fourth box-plate 214 to be in the open state, and the second box-plate driving mechanism drives the second box-plate 215 to continue rotating in the open state. Thus, the first box-plate 212, the second box-plate 215, the third box-plate 213, and the fourth box-plate 214 open the opening end of the carton 4. Then, the infeed driving mechanism 3 drives the pusher plate 311 to move horizontally, thereby feeding a stack of products 6 located on the receiving plate 4 into the carton 4. This embodiment incorporates a rotatable support plate (II) between the carton-feeding mechanism and the carton-supporting mechanism, making it a shared component of both mechanisms. During material receiving, the support plate (II) forms a receiving compartment with other components of the carton-feeding mechanism. During carton support, it forms a carton-supporting structure. Furthermore, when the support plate (II) rotates to become the carton-supporting structure, it simultaneously creates a pushing channel, allowing the pusher plate of the carton-feeding mechanism to smoothly push a stack of products into the carton along this channel. Thus, this embodiment cleverly integrates the support plate (II) with the carton-feeding mechanism through structural design, significantly improving the integration level of the carton-feeding and carton-supporting mechanisms, simplifying the overall structure of the flexible packaging bag carton-feeding device, reducing the occupied volume space, and lowering manufacturing costs.

[0033] like Figure 2 As shown, the box-feeding drive mechanism 3 further includes a box-feeding device pushing linear mechanism 312 and a pushing rod 313 connected to the box-feeding device pushing linear mechanism 312. A pushing plate 311 is disposed on the pushing rod 313, and under the push of the box-feeding device pushing linear mechanism 312, it can drive the pushing plate 311 to move back and forth in the horizontal direction. The box-feeding device pushing linear mechanism 312 can be a linear motor drive mechanism.

[0034] like Figure 2 and Figure 9 As shown, the receiving plate 4 is connected to the receiving linear mechanism 7 of the box-feeding device. Under the drive of the receiving linear mechanism 7, the receiving plate 4 can move vertically up and down. The receiving linear mechanism 7 of the box-feeding device can also be a linear motor drive mechanism.

[0035] During material receiving, the receiving plate 4 is positioned above the receiving hopper. After receiving a fallen flexible packaging bag, the receiving plate 4, driven by the linear receiving mechanism 7 of the box-entry device, descends a certain position to receive the next flexible packaging bag. This process is repeated until a stack of products 6 is formed on the receiving plate 4. At this point, the receiving plate 4 descends to a position below the receiving hopper. This method of receiving reduces the falling height of the flexible packaging bags, preventing damage to them.

[0036] like Figure 3 As shown, multiple linked support plates, namely support plate one 212, support plate three 213, and support plate four 214, are included. The support plate driving mechanism includes a support plate protrusion 8 with an inclined groove on each of the linked support plates and a support cylinder one 10 on one side of the door frame plate 211. A support plate moving shaft 9 is provided in the inclined groove of each support plate protrusion 8. The support plate moving shaft 9 passes through the inclined groove and is slidably connected to the inclined groove. Multiple support plate moving shafts 9 are connected into a single structure. In this embodiment, the support plate moving shaft 9 connected into a single structure is U-shaped. The piston rod of the support cylinder one 10 is connected to the support plate moving shaft 9 of the single structure. Under the drive of the support cylinder one 10, the support plate moving shaft 9 of the single structure can move along the horizontal direction (e.g., Figure 3 The arrow in the image moves back and forth, thereby using the cooperation between the support plate moving shaft and the inclined groove to drive multiple linked support plates to open or close.

[0037] This embodiment utilizes a structure where the moving shafts of the support plates engage with inclined grooves to move multiple support plates into open or retracted states, thereby expanding the carton. Its overall structure is simple, compact, and low-cost. By connecting the moving shafts of the support plates into a single unit, a linkage structure for multiple support plates is achieved, further simplifying the device structure.

[0038] like Figure 3 and Figure 10 As shown, the inclined groove 811 is a through hole, and its length direction is inclined at a certain angle to the horizontal movement direction of the support plate moving shaft 9. A roller 11 is sleeved on the support plate moving shaft 9 passing through the inclined groove 811. The roller 11 is slidably connected to the inner circumferential surface of the inclined groove 811, thereby enabling the support plate moving shaft to slide in the inclined groove. The use of a roller and sliding groove structure to achieve the sliding connection between the support plate moving shaft and the inclined groove can reduce the mutual friction and improve the service life.

[0039] In this embodiment, the roller 11 may be a bearing. To ensure the smoothness of the roller 11 during sliding, a sliding groove 8111 is also provided on the inner circumferential surface of the inclined groove 811. During operation, the roller 11 slides back and forth along the sliding groove 8111.

[0040] Multiple bearing seats 12 are also provided on the door frame plate 211, and a support plate pivot 13 is provided at each support plate. The support plate pivot 13 is rotatably connected to the door frame plate 211 through the bearing seat 12. A pivot connecting block 14 is also provided on the side of each linkage support plate. The pivot connecting block 14 is connected to the support plate pivot 13, thereby rotatably connecting the support plate to one side of the door frame plate 211.

[0041] like Figure 4 and Figure 11 As shown, the independent support box plate includes a second support box plate 215, which is controlled to rotate by an independent support box plate drive mechanism. The second support box plate 215 is provided with a second support box plate rotating shaft 15, and a second rotating shaft bearing seat 16 is provided on the door frame plate 211. The second support box plate rotating shaft 15 and the second rotating shaft bearing seat 16 are connected to each other, so that the second support box plate 215 is rotatably connected to one side of the door frame plate 211. The second support box plate drive mechanism includes a second support box cylinder 18 provided on the door frame plate 211. A rack 181 is connected to the piston rod of the second support box cylinder 18, and a gear 151 is also provided at one end of the second support box plate rotating shaft 15. The rack 181 and the gear 151 are connected to each other, so that when the second support box cylinder 18 is activated, one end of the second support box plate 215 can be driven to rotate around the second support box plate rotating shaft 15. When receiving materials, the support cylinder 218 is activated, and the rack 181 and gear 151 drive the support plate 215 to rotate until it is parallel to the push plate 311 (e.g., ...). Figure 4 (in the state of the middle), thus forming a receiving bin. When the box-supporting operation is performed, the linked box-supporting plates, namely box-supporting plate one 212, box-supporting plate three 213 and box-supporting plate four 214, are activated by box-supporting cylinder one 10. The moving shaft of the box-supporting plate and the inclined groove are used to drive the opening of multiple linked box-supporting plates, and the independent box-supporting plate, namely box-supporting plate two 215, is activated by box-supporting cylinder two 18. The rack one 181 and the gear one 151 are used to drive the rotation of the independent box-supporting plate (such as... Figure 4 (As shown by the arrow in the image), this causes the independent support panels to open, thus opening the carton.

[0042] In summary, this utility model incorporates a rotatable support plate (II) between the carton-feeding mechanism and the carton-supporting mechanism, making II a shared component of both mechanisms. During material receiving, II forms a receiving compartment with other components of the carton-feeding mechanism. During carton support, II forms a carton-supporting structure. Furthermore, when II rotates to its supporting position, it simultaneously creates a pushing channel, facilitating the feeding plate of the carton-feeding mechanism to smoothly push a stack of products into the carton. Thus, this utility model cleverly integrates II with the carton-feeding mechanism through structural design, significantly improving the integration of the carton-feeding and supporting mechanisms, simplifying the overall structure of the flexible packaging bag carton-feeding device, reducing the occupied volume, and lowering manufacturing costs. By setting a moving shaft and inclined groove structure for the support plates, multiple support plates are moved to open or retract, thereby opening the carton. The overall structure is simple, compact, and low-cost. By connecting the moving shafts of the support plates into one unit, a linkage structure of multiple support plates is realized, thereby further simplifying the device structure.

[0043] In this embodiment, "multiple" refers to "two or more". The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of this utility model. Therefore, all equivalent technical solutions should also fall within the protection scope of this utility model, which is defined by the claims.
