Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, specifically to an anti-falling mechanism for a straw palletizing machine. Background Technology

[0002] Palletizers are important equipment in the fields of agriculture and biomass energy. They compress straw and stack it into piles for easy transportation and storage.

[0003] According to CN221894159U, a bridge-type palletizer anti-drop structure is disclosed. This technology addresses the issue that salt bags are prone to falling during the palletizer's operation, and it cannot simultaneously palletize multiple sets of salt bags, posing a safety hazard due to the lack of a protective structure. The proposed solution is a bridge-type palletizer anti-drop structure, including a fixed frame, protective components, moving components, and transfer components. This structure offers several advantages: "The protective components prevent personnel from entering dangerous areas and provide some obstruction when salt bags fall during palletizing. The moving components allow the front and rear transfer components to be staggered for palletizing operations. The transfer components improve the stability of the connecting plate's lifting and lowering, preventing displacement or detachment. The gripper provides stable gripping functionality, preventing salt bags from falling during transfer."

[0004] The above-mentioned design, which uses left and right clamping plates in conjunction with bottom grab bars for lifting, has the following significant problems in practical applications: First, the lateral pressure applied by the clamping plates may cause the straw bales to deform. When the bales are excessively compressed, the contact area between them and the bottom grab bars is greatly reduced, seriously affecting the lifting effect. Second, this design lacks effective constraints in the front-back direction. When the palletizer makes sudden stops, accelerations, or turns, the straw bales will slide in the front-back direction due to inertia, posing a serious risk of falling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-fall mechanism for a straw stacking machine. By using the anti-fall component, the displacement of the straw bales in the front-to-back direction is effectively constrained, solving the problem of material slipping back and forth under inertia in traditional stacking machines. Furthermore, it can adapt to the gripping needs of straw bales of different sizes, improving versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-fall mechanism for a straw stacking machine, comprising a frame, wherein a stacking mechanism is mounted on the frame for gripping and stacking straw bales, the stacking mechanism comprising:

[0007] Action components, mounted on the rack and used to control movement;

[0008] The gripping component includes a mounting plate set on the moving component. A crossbeam is fixed to the bottom of the mounting plate. A shaft is fixed to both ends of the crossbeam. A shaft rod is rotatably mounted at the lower end of the shaft rod. A swing arm is fixed to both ends of the shaft rod. A connecting plate is fixed between the two swing arms. Several gripping hooks are fixed to the lower end of the connecting plate.

[0009] The anti-fall component includes a transmission gear rotatably mounted in the middle of the outer wall of the connecting plate, a guide rail fixed to the outer wall of the connecting plate, a slide bracket slidably mounted at both ends of the guide rail, a rack fixed to the inner end of the slide bracket and meshing with the transmission gear for transmission, an anti-fall bar fixed to the outer end of the slide bracket, and a second cylinder mounted on the outer wall of the connecting plate for driving one of the slide brackets to move.

[0010] Preferably, the gripping assembly further includes a lug fixed in the middle of the outer wall of the shaft, a first cylinder is pivotally connected to the upper end of the shaft frame, and the output end of the first cylinder is pivotally connected to the upper end of the lug.

[0011] Preferably, the gripping assembly further includes a mounting base fixed to the inner end of the shaft frame, on which a three-axis cylinder is mounted, and a pressure plate is fixed to the output end of the three-axis cylinder.

[0012] Preferably, the gripping assembly also includes buffers fixed to both ends of the shaft.

[0015] Beneficial effects

[0016] This utility model provides an anti-falling mechanism for a straw stacking machine. Compared with the prior art, it has the following advantages:

[0017] 1. The second cylinder drives the slide to slide along the guide rail. At the same time, the slide drives the transmission gear to rotate through the rack. The transmission gear drives another slide to move along the guide rail through another rack. This makes the slides at both ends drive the anti-fall bars at both ends to move synchronously in opposite directions, effectively restraining the displacement of the straw bales in the front and back directions. This solves the problem of material slipping back and forth under the action of inertia in traditional palletizers. It can also adapt to the gripping needs of straw bales of different sizes and improve versatility.

[0018] 2. The output end of the first cylinder drives the shaft to rotate, and the shaft drives the connecting plate through the swing arm and cooperates with the grab hook to grab the straw bale; then the output end of the three-axis cylinder drives the pressure plate to press down the straw bale, forming an upper and lower clamp with the grab hook to prevent the loose straw bale from scattering during transportation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an anti-fall mechanism for a straw stacking machine, including a frame 1, on which a stacking mechanism 2 is provided for grabbing and stacking straw bales, the stacking mechanism 2 including:

[0027] Action component 21, mounted on rack 1 and used for controlling movement;

[0028] The gripping component 22 includes a mounting plate 221 mounted on the moving component 21. A crossbeam 222 is fixed to the bottom of the mounting plate 221. A shaft frame 223 is fixed to both ends of the crossbeam 222. A shaft rod 224 is rotatably mounted at the lower end of the shaft frame 223. A swing arm 225 is fixed to both ends of the shaft rod 224. A connecting plate 226 is fixed between the two swing arms 225. A plurality of gripping hooks 227 are fixed to the lower end of the connecting plate 226.

[0029] The anti-fall component 23 includes a transmission gear 231 rotatably mounted in the middle of the outer wall of the connecting plate 226, a guide rail 232 fixed to the outer wall of the connecting plate 226, a slide 233 slidably mounted at both ends of the guide rail 232, a rack 234 fixed to the inner end of the slide 233 and meshing with the transmission gear 231 for transmission, an anti-fall bar 235 fixed to the outer end of the slide 233, and a second cylinder 236 mounted on the outer wall of the connecting plate 226 for driving one of the slides 233 to move.

[0030] In this embodiment, after the straw bale is grabbed by the gripping component 22, the second cylinder 236 drives the slide 233 to slide along the guide rail 232. At the same time, the slide 233 drives the transmission gear 231 to rotate through the rack 234. The transmission gear 231 drives another slide 233 to move along the guide rail 232 through another rack 234. This causes the slides 233 at both ends to drive the anti-fall bars 235 at both ends to move synchronously in opposite directions, effectively restraining the displacement of the straw bale in the front and back directions. This solves the problem of material slipping back and forth under the action of inertia in traditional palletizers, and can adapt to the gripping needs of straw bales of different sizes, improving versatility.

[0031] Specifically, the gripping component 22 also includes a lug 228 fixed in the middle of the outer wall of the shaft 224, and a first cylinder 229 is pivotally connected to the upper end of the shaft bracket 223, and the output end of the first cylinder 229 is pivotally connected to the upper end of the lug 228.

[0032] In this embodiment, the output end of the first cylinder 229 drives the shaft lug 228 to rotate the shaft 224. The shaft 224 drives the connecting plate 226 through the swing arm 225 and cooperates with the grab hook 227 to grab the straw bale.

[0033] Specifically, the gripping component 22 also includes a mounting base 2210 fixed to the inner end of the shaft frame 223. A three-axis cylinder 2211 is mounted on the mounting base 2210, and a pressure plate 2212 is fixed to the output end of the three-axis cylinder 2211.

[0034] In this embodiment, after the straw bale is grabbed, the output end of the three-axis cylinder 2211 drives the pressure plate 2212 to press down on the straw bale, forming an upper and lower clamp with the grab hook 227 to prevent the loose straw bale from scattering during transportation.

[0035] Specifically, the gripping component 22 also includes buffers 2213 fixed at both ends of the shaft bracket 223.

[0036] In this embodiment, the buffer 2213 can absorb the vibration when the swing arm 225 opens, reduce the impact during the grasping process, and reduce the risk of material falling.

[0037] Specifically, the motion component 21 includes an X-axis linear guide 211 fixed to the upper end of the frame 1, a Y-axis linear guide 212 fixed to the slider of the X-axis linear guide 211, a Z-axis linear guide 213 fixed to the slider of the Y-axis linear guide 212, and a rotation component 214 provided on the Z-axis linear guide 213 for driving the gripping component 22 to rotate.

[0038] In this embodiment, the X-axis linear guide 211, Y-axis linear guide 212 and Z-axis linear guide 213 are combined to achieve precise positioning at any position in space, meeting the requirements of complex stacking structures.

[0039] Specifically, the rotating assembly 214 includes a housing 2141 fixed to the lower end of the Z-axis linear guide 213. A driven gear 2142 is rotatably mounted inside the housing 2141, and a mounting plate 221 is fixed to the bottom of the driven gear 2142. A servo motor 2143 is mounted on the top of the housing 2141, and a drive gear 2144 is fixed to the output end of the servo motor 2143 and meshes with the driven gear 2142 for transmission.

[0040] In this embodiment, the output end of the servo motor 2143 drives the active gear 2144 to rotate. The active gear 2144 drives the straw bundle gripped on the gripping component 22 to rotate through the driven gear 2142, so that the straw bundle can adjust its angle when stacking.

[0041] The working principle and usage process of this utility model are as follows: First, the output end of the first cylinder 229 drives the shaft lug 228 to rotate the shaft 224. The shaft 224 drives the connecting plate 226 through the swing arm 225 and cooperates with the grab hook 227 to grab the straw bale. Then, the output end of the three-axis cylinder 2211 drives the pressure plate 2212 to press down the straw bale, forming an upper and lower clamp with the grab hook 227 to prevent the loose straw bale from scattering during transportation.

[0042] Then, the second cylinder 236 drives the slide 233 to slide along the guide rail 232. At the same time, the slide 233 drives the transmission gear 231 to rotate through the rack 234. The transmission gear 231 drives another slide 233 to move along the guide rail 232 through another rack 234. This causes the slides 233 at both ends to drive the anti-fall bars 235 at both ends to move synchronously in opposite directions, effectively restraining the displacement of the straw bales in the front and back directions. This solves the problem of material slipping back and forth under the action of inertia in traditional palletizers, and can adapt to the gripping needs of straw bales of different sizes, improving versatility.
