Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, and in particular to an anti-tipping structure for a palletizing machine. Background Technology

[0002] A palletizer is a device that automatically stacks pre-packed cartons onto pallets or stacks (wooden or plastic) in a specific arrangement. Multiple layers can be stacked, and the stacked materials are then pushed out for easy transport by forklift to the warehouse. This equipment uses PLC and touchscreen control for intelligent operation and management, making it simple and easy to master. It significantly reduces labor and labor intensity. Palletizers automatically stack bags, cartons, or other packaging materials from a conveyor belt according to customer process requirements and then transport the stacked materials. Therefore, an anti-tipping structure is required for palletizing.

[0003] A search revealed Chinese Patent Publication No. CN222330969U, which discloses an anti-tipping structure for palletizing machines. The structure includes a placement plate, an anti-tipping mechanism, and a loading mechanism. Each placement plate has conveyor wheels at its bottom and a pusher welded to one end of its outer wall. A cargo box is placed on top of the placement plate. The anti-tipping mechanism is welded to the outer perimeter of the top of the placement plate and includes side plates, latches, fixing rods, movable plates, and handles. The side plates are welded to the outer perimeter of the top of the placement plate, and latches are fixedly connected to the surface of each side plate. This anti-tipping structure for palletizing machines allows for the removal of movable plates from the anti-tipping mechanism around the placement plate when the cargo box is placed on the placement plate. The height of the movable plate is fixed by the fixing rod. The side plates and movable plates protect the cargo box from tipping over due to its height.

[0004] While the above solution has the advantage of preventing cargo from tipping over due to excessive height, gaps still exist between the side panels and the cargo box during actual use. As a result, the cargo box is prone to tipping over under external force during transportation, making it inconvenient to use.

[0005] Therefore, there is an urgent need to provide an anti-tipping structure for palletizing machines to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, which still has gaps between the side plate and the cargo box in actual use, and the cargo box is easy to tip over under external force during transportation, making it inconvenient to use. This utility model provides an anti-tipping structure for a palletizer.

[0007] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: an anti-tipping structure for a palletizer, comprising a base plate, a support fixedly mounted on the top of the base plate, and further comprising:

[0008] A protective component is disposed on the top of the support base;

[0009] The protective assembly includes a protective plate disposed on the top surface of the support, a rotating sleeve disposed in the middle of the protective plate, a rotating rod movably disposed in the middle of the rotating sleeve, and a locking unit disposed at the bottom of the rotating rod. A support unit is disposed on the outer side of the rotating sleeve.

[0010] The present invention is further configured such that: the number of protective components is four sets, and the four sets of protective components form a rectangular structure.

[0011] The present invention is further configured such that: a limiting ring is fixedly connected to the outer side of the rotating rod, and a threaded cylinder is movably provided on the top of the limiting ring, and the threaded cylinder is threadedly connected to the outer surface of the rotating sleeve.

[0012] The present invention is further configured such that: there are two sets of locking units, and the two sets of locking units are arranged opposite to each other at the bottom of the rotating rod;

[0013] The locking unit includes a storage groove located at the bottom of the inner side of the protective plate, a locking rod movably located inside the storage groove, a limiting plate installed on the outside of the locking rod, and a pressing member located on the side of the limiting plate. One end of the locking rod is provided with a beveled surface, and a conical block is provided in the middle of the two locking rods. The conical block is installed at the bottom of the rotating rod.

[0014] The top edge of the support seat is provided with a placement groove, and the opposite sidewalls of the placement groove are provided with locking grooves. One end of the locking rod is adapted to the size of the locking groove.

[0015] The present invention is further configured such that: there are two sets of support units, and the two sets of support units are arranged opposite to each other on the outside of the rotating sleeve;

[0016] The support unit includes a bidirectional lead screw movably disposed inside the protective plate, a slide block disposed opposite to the outside of the bidirectional lead screw, and a support plate disposed on the side of the slide block. One end of each of the two slide blocks is movably connected to one end of a movable rod, and the other end of the movable rod is movably connected to the side of the support plate.

[0017] The outer surface of the rotating sleeve is equipped with a first bevel gear, and a second bevel gear meshes with the side of the first bevel gear. The second bevel gear is installed at the end of the bidirectional lead screw.

[0018] The present invention is further configured such that: the support unit also includes a crossbar installed at the corner of the side of the support plate, one end of the crossbar extending through to the outside of the protective plate, and a limit block is installed at one end of the crossbar.

[0019] The present invention is further configured such that: a groove is provided on the inner side of the protective plate, and the support plate is disposed inside the groove.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, through its protective components, places the cargo box on top of the support base. Pulling the protective plate upwards raises it above the height of the cargo box. Pressing down on the rotating rod pushes the conical block downwards. As the conical block moves downwards, it presses against the beveled end of the locking rod, causing the locking rod to slide along the inside of the receiving groove towards the outside of the protective plate. This engages one end of the locking rod with the locking groove, thus limiting the overall position of the protective plate. The four protective plates, together forming a rectangular structure, provide all-around protection for the cargo box. Then, by rotating the threaded cylinder to connect it with the outer surface of the rotating sleeve, the rotating rod and the rotating sleeve are fixedly connected. Then, by rotating the rotating rod, the rotating sleeve is driven to rotate, thereby driving the first bevel gear to rotate. Since the first bevel gear meshes with the second bevel gear, it drives the double-acting screw to rotate. Under the action of the threaded pair, the two slides slide along the outer side of the double-acting screw. When the slides slide, they will work with the movable rod to push the support plate to move outward, so that the support plate abuts against the cargo box, preventing the cargo box from shaking during transportation, preventing the cargo box from tipping over, and facilitating use.

[0030] Please see Figures 1-6 An anti-tipping structure for a palletizer includes a base plate 1, a support seat 2 fixedly mounted on the top of the base plate 1, and further includes:

[0031] Protective component 3 is located on the top of the support base 2. The protective component 3 is used to add a protective structure to the top edge of the support base 2 to prevent the cargo box from tipping over and falling.

[0032] The protective assembly 3 includes a protective plate 31 disposed on the top surface of the support 2, a rotating sleeve 32 disposed in the middle of the protective plate 31, a rotating rod 33 movably disposed in the middle of the rotating sleeve 32, and a locking unit 34 disposed at the bottom of the rotating rod 33. A support unit 35 is disposed on the outer side of the rotating sleeve 32, and the rotating sleeve 32 is rotatably connected to the top of the protective plate 31.

[0033] There are four sets of protective components 3, which together form a rectangular structure to provide all-around protection for the top of the support 2.

[0034] Among them, the outer side of the rotating rod 33 is fixedly connected to the limiting ring 331, and the top of the limiting ring 331 is movably provided with a threaded cylinder 332. The threaded cylinder 332 is threadedly connected to the outer surface of the rotating sleeve 32. The rotating rod 33 and the rotating sleeve 32 are fixedly connected through the threaded connection of the threaded cylinder 332 and the rotating sleeve 32.

[0035] There are two sets of locking units 34, which are arranged opposite to each other at the bottom of the rotating rod 33.

[0036] The locking unit 34 includes a storage groove disposed on the inner bottom of the protective plate 31, a locking rod 341 movably disposed inside the storage groove, a limiting plate 342 installed on the outer side of the locking rod 341, and a pressing member 343 disposed on the side of the limiting plate 342. Preferably, the pressing member 343 is a compression spring, and the two ends of the pressing member 343 are respectively fixedly connected to the side of the limiting plate 342 and the side wall of the storage groove. One end of the locking rod 341 is provided with a beveled surface, and a conical block 344 is provided in the middle of the two locking rods 341. The conical block 344 is installed at the bottom of the rotating rod 33.

[0037] A placement groove is provided at the top edge of the support seat 2, and locking grooves are provided on the opposite side walls of the placement groove. One end of the locking rod 341 is adapted to the size of the locking groove.

[0038] There are two sets of support units 35, which are arranged opposite to each other on the outside of the rotating sleeve 32.

[0039] The support unit 35 includes a bidirectional lead screw 351 movably disposed inside the protective plate 31, a slide block 352 disposed opposite to the outside of the bidirectional lead screw 351, and a support plate 353 disposed on the side of the slide block 352. One end of each slide block 352 is movably connected to one end of a movable rod 354, and the other end of the movable rod 354 is movably connected to the side of the support plate 353. Preferably, the connection between the movable rod 354 and the side of the support plate 353 and one end of the slide block 352 is a rotatable connection, and the slide block 352 is threadedly connected to the outside of the bidirectional lead screw 351.

[0040] A first bevel gear 355 is mounted on the outer surface of the rotating sleeve 32, and a second bevel gear 356 meshes with the side of the first bevel gear 355. The second bevel gear 356 is mounted on the end of the bidirectional lead screw 351.

[0041] The support unit 35 also includes a crossbar 357 installed at the corner of the side of the support plate 353. One end of the crossbar 357 extends through to the outside of the protective plate 31, and a limit block is installed at one end of the crossbar 357.

[0042] The inner side of the protective plate 31 is provided with a groove, and the support plate 353 is disposed inside the groove.

[0043] In use, this invention first places the cargo box on top of the support base 2 using an external palletizer. Then, the protective plate 31 is pulled upwards to raise it above the height of the cargo box. Next, the rotating rod 33 is pressed downwards to push the conical block 344 downwards. As the conical block 344 moves downwards, it squeezes the end of the locking rod 341 with a beveled surface, causing the locking rod 341 to slide along the inside of the receiving groove towards the outside of the protective plate 31. This allows one end of the locking rod 341 to engage with the locking groove, thus limiting the overall position of the protective plate 31. The four protective plates 31 together form a rectangular structure, providing all-around protection for the cargo box. The screw rod 33 is fixedly connected to the rotating sleeve 32 by rotating the screw cylinder 332 and then rotating the rotating sleeve 32 by rotating the screw rod 33. This causes the rotating sleeve 32 to rotate, which in turn causes the first bevel gear 355 to rotate. Since the first bevel gear 355 meshes with the second bevel gear 356, it causes the double-acting screw 351 to rotate. Under the action of the threaded pair, the two slide blocks 352 slide along the outside of the double-acting screw 351. When the slide blocks 352 slide, they push the support plate 353 to move outward through the movable rod 354, so that the support plate 353 abuts against the cargo box and prevents the cargo box from shaking during transportation.
