[0032] A paper bag compacting device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A paper bag compacting device according to an embodiment of the utility model includes a frame 100, a material pressing mechanism, a guide plate 170 and an alignment mechanism.

[0034] For the frame 100, the frame 100 includes a frame body 110 and a top plate 120, a pressing space 130 is arranged under the top plate 120, and a material opening 140 is provided on the front side of the pressing space 130. The pressing space 130 is used to accommodate a pallet and paper bags stacked on the pallet, so that a forklift can push the pallet and the paper bags stacked on the pallet from the material opening 140 into the pressing space 130.

[0035] As for the pressing mechanism, the pressing mechanism includes a pressing plate 150 and a first oil cylinder 160 for driving the pressing plate 150 to rise and fall. The pressing plate 150 is located in the pressing space 130. The first oil cylinder 160 is fixed on the top plate 120. The pressing plate 150 is used to compact the paper bags. Thus, the first oil cylinder 160 drives the pressing plate 150 to descend, so that the pressing plate 150 presses the stacked paper bags downward, and then quickly compacts the stacked paper bags, making the bonding at the joints of the paper bags more firm.

[0036] In some specific embodiments, two first oil cylinders 160 are provided, and the two first oil cylinders 160 are symmetrical along the center line of the pressing plate 150 , so that the force on the pressing plate 150 is more balanced.

[0037] In some specific embodiments, a flange 320 is provided at the bottom end of the telescopic rod of the first oil cylinder 160 , and the pressing plate 150 and the flange 320 are connected by bolts, thereby facilitating the disassembly and replacement of the pressing plate 150 .

[0038] Furthermore, the pressing plate 150 has a first groove 330 penetrating from front to back, and the first groove 330 accommodates the fork of a forklift so that the forklift can lift the pressing plate 150 , thereby facilitating the transportation of the pressing plate 150 .

[0039] As for the guide plate 170, the guide plate 170 is located at the bottom of the pressing space 130. Two guide plates 170 are provided, and the two guide plates 170 are arranged opposite to each other. The guide plate 170 includes an inclined section 180 and a straight section 190. One end of the inclined section 180 is located at the material port 140, and the other end of the inclined section 180 extends toward the rear side of the pressing space 130 and connects to the straight section 190. One end of the inclined section 180 away from the material port 140 is inclined toward the side close to the other guide plate 170. The two inclined sections 180 cooperate to guide the support plate, and the two straight sections 190 cooperate to limit the support plate.

[0040] It can be understood that, in the process of the forklift pushing the pallet and the paper bags stacked on the pallet from the material port 140 into the pressing space 130, the pallet first passes through the inclined section 180. When the pallet passes through the inclined section 180, the two inclined sections 180 cooperate to guide the pallet so that the position of the pallet can be corrected toward the center of the two inclined sections 180, so that the pallet can accurately enter between the two straight sections 190. After the pallet enters the straight section 190, the two straight sections 190 cooperate to limit the pallet. Therefore, the two guide plates 170 cooperate to correct the left and right position of the pallet, so that the placement of the pallet in the pressing space 130 is more accurate.

[0041] In some specific embodiments, the frame 100 is further provided with a limit plate 310, which connects one end of the two straight sections 190 away from the inclined section 180. The limit plate 310 abuts against the support plate to limit the depth of the support plate entering the pressing space 130, thereby making the depth of the support plate entering the pressing space 130 more accurate.

[0042] As for the alignment mechanism, the alignment mechanism is located between the top plate 120 and the guide plate 170, and the alignment mechanism includes a left alignment plate 200, a right alignment plate 210, a front alignment plate 220 and a rear alignment plate 230. The left alignment plate 200 and the right alignment plate 210 are close to each other to clamp and align the left and right sides of the paper bag, and the front alignment plate 220 and the rear alignment plate 230 are close to each other to clamp and align the front and back sides of the paper bag.

[0043] It can be understood that after the paper bag enters the pressing space 130, before the pressing plate 150 presses the paper bag, the left alignment plate 200 and the right alignment plate 210 are close to each other to clamp the left and right sides of the paper bag, so that the left and right sides of the stacked paper bags are aligned up and down. At the same time, the front alignment plate 220 and the rear alignment plate 230 are close to each other to clamp the front and back sides of the paper bag, so that the front and back sides of the stacked paper bags are aligned up and down. Furthermore, the compacting device can straighten and align the paper bags after they are transported into place and then compact them, thereby reducing the risk of collapse of the paper bags during the compaction process.

[0044] Specifically, the left alignment plate 200 , the right alignment plate 210 , and the rear alignment plate 230 are all driven by oil cylinders.

[0045] In some specific embodiments, the alignment mechanism further includes a first translation seat 240, and the first translation seat 240 is used to drive the front alignment plate 220 to move left and right to approach the front side of the paper bag or move away from the front side of the paper bag.

[0046] It can be understood that when the alignment mechanism needs to straighten and align the paper bag, the first translation seat 240 drives the front alignment plate 220 to move leftward or rightward close to the front side of the paper bag, so that the front alignment plate 220 can abut the front side of the paper bag when it moves in the front-to-back direction close to the rear alignment plate 230. When the alignment mechanism completes the straightening and alignment of the paper bag, the first translation seat 240 drives the front alignment plate 220 to the leftward or rightward away from the front side of the paper bag to prevent the front alignment plate 220 from interfering with the discharge or feeding of the paper bag from the material port 140.

[0047] In some specific embodiments, the frame 110 is provided with a first guide rod 250 that slides forward and backward, and the first guide rod 250 extends left and right. The frame 110 is also provided with a second cylinder 260, and the second cylinder 260 is used to drive the first guide rod 250 to move forward and backward. The first translation seat 240 is connected to the first guide rod 250 for left and right sliding.

[0048] It can be understood that by sliding the first translation seat 240 on the first guide rod 250, the first guide rod 250 can guide the translation of the first translation seat 240, making the translation of the first translation seat 240 smoother. At the same time, the second cylinder 260 can drive the front alignment plate 220 to move forward and backward by driving the first guide rod 250 to move forward and backward.

[0049] In some specific embodiments, the frame 110 has two slide grooves 270, which extend forward and backward. The two slide grooves 270 respectively accommodate the sliding of the two ends of the first guide rod 250, so that the slide grooves 270 can cooperate with the first guide rod 250 to limit the position, thereby making the sliding of the first guide rod 250 on the frame 110 more stable.

[0050] In some specific embodiments, two second oil cylinders 260 are provided, and the two second oil cylinders 260 are respectively connected to two ends of the first guide rod 250 , so that the force on the first guide rod 250 is more balanced.

[0051] In some specific embodiments, the front alignment plate 220 includes a left half plate 280 and a right half plate 290, and two first translation seats 240 are provided. The left half plate 280 is provided on one first translation seat 240, and the right half plate 290 is provided on another first translation seat 240. The left half plate 280 and the right half plate 290 are close to each other to be close to the front side of the paper bag, and the left half plate 280 and the right half plate 290 are away from each other to be away from the front side of the paper bag. Thus, the left half plate 280 and the right half plate 290 can move to both sides of the paper bag respectively, so that the position arrangement of the front alignment plate 220 in the pressing space 130 is more reasonable, and then, the paper bag can be placed in the middle of the pressing space 130.

[0052] Furthermore, third oil cylinders 300 are disposed at both ends of the first guide rod 250 , and one third oil cylinder 300 drives one first translation seat 240 to translate, so that the movement directions of the two first translation seats 240 can be opposite.

[0053] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
