Description

Technical Field

[0001] This utility model relates to the field of palletizer maintenance technology, specifically a multi-purpose support frame for palletizer maintenance. Background Technology

[0002] A palletizer is a machine that automatically stacks cartons already packed in containers onto pallets, wooden or plastic pallets in a specific arrangement. It can stack multiple layers and then pushes them out for easy transport to the warehouse by forklift. Medium and low-level palletizers mainly consist of a flattening conveyor, a slow-stop conveyor, a rotation conveyor, a pallet bin, a pallet conveyor, a grouping machine, a bag pushing device, a palletizing device, and a pallet conveyor.

[0003] In the existing technology, when a palletizer malfunctions and needs to be repaired, maintenance personnel need to use a crane to place the palletizer flat on a support frame. This facilitates the repair of the palletizer. However, since the size of the support frame is fixed and the size of the palletizer varies greatly, different sized support frames need to be replaced to support palletizers of different sizes, which reduces the practicality of the support frame.

An installation groove 15 is provided in the center of the top wall of the fixed plate 11. A bidirectional screw 16 is rotatably connected to the center of the inner side of the installation groove 15. During rotation, the bidirectional screw 16 allows the left and right threaded blocks 26 to move closer or further apart. Both sides of the right side are threaded with threaded blocks 26, and the top walls of the threaded blocks 26 are fixedly connected with connecting plates 17. The connecting plates 17 serve to connect and fix the threaded blocks 26 and the L-shaped support plates 18. The top of the connecting plates 17 is fixedly connected with the L-shaped support plates 18. The four corners of the bottom wall of the mounting plate 1 are provided with casters 20. The right side wall of the mounting plate 1 is fixedly connected with a handle 25. The middle of the left side wall of the fixing plate 11 is rotatably connected with a knob 19. Rotating the knob 19 can rotate the bidirectional screw 16, thereby adjusting the position of the L-shaped support plate 18. The knob 19 is fixedly connected with the bidirectional screw 16.

[0025] Limiting blocks 14 are fixedly connected to the front and rear sides of the bottom of the connecting plate 17 respectively. Threaded blocks 26 are slidably connected to the left and right sides of the inner side of the mounting groove 15 respectively. A lifting plate 9 is fixedly connected to the bottom of the fixing plate 11. Moving rods 7 are rotatably connected to the left and right ends of the rear side of the bottom of the lifting plate 9. A connecting rod 10 is fixedly connected to the upper middle part between the two sets of moving rods 7. The connecting rod 10 serves to connect the output end of the cylinder 8 with the two sets of moving rods 7.

[0026] The bottom of each moving rod 7 is rotatably connected to a positioning rod 6, which is slidably connected to the inner side of a limiting groove 5. The limiting groove 5 is respectively set on the front side of the middle of the left and right walls of the mounting frame 3. The left and right sides of the rear end of the inner side of the mounting frame 3 are rotatably connected to support rods 4, which are rotatably connected to the middle of the moving rod 7. The top of each support rod 4 is slidably connected to the front side of the inner side of the lifting plate 9. The moving rod 7, positioning rod 6, support rod 4, mounting frame 3, cylinder 8, lifting plate 9 and connecting rod 10 constitute a lifting platform, which are all existing public technologies, so they will not be described in detail.
