Description

Technical Field

[0001] The utility model belongs to the technical field of paper pallet production and processing, and specifically relates to a compression device for paper pallet production. Background Art

[0002] Paper pallets are a type of pallet made from pulp and cardboard. They are light weight, high strength, good toughness, not easy to deform, shockproof, heat-insulating and sound-insulating. They are widely used in loading and unloading and transporting small quantities of materials. During the production and processing of paper pallets, the cardboard needs to be compressed and formed using corresponding compression devices according to actual needs.

[0003] At present, hydraulic presses are mainly used as compression devices for the production of paper pallets. When in use, the molding die is assembled on the hydraulic press, and the paper pallet is compressed and molded by driving the molding die to close the mold through the hydraulic press.

[0004] Most of the paper pallet production compression devices in the prior art adopt a single-station compression processing method for production. The specific compression process is mostly: material discharge, compression, and material removal. The operator needs to manually remove the material after the paper pallet is compressed. Such processing and material removal methods not only make the unit processing cycle of the paper pallet production compression device longer and the compression molding efficiency lower, but also the manual material removal has greater safety hazards, resulting in poor compression safety of the paper pallet production compression device.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

The multiple groups of Green columns 215 play the role of supporting and lifting and moving limit for the driving upper die seat 214.

[0047] like Figures 1 to 3 As shown, a top plate 216 is fixedly installed on the top of the plurality of Green columns 215. The top plate 216 supports and fixes the hydraulic cylinder 217, and at the same time, the top plate 216 plays a role of moving and limiting the driving upper die seat 214.

[0048] like Figures 1 to 3As shown, a hydraulic cylinder 217 is fixedly installed above the top plate 216, and the telescopic shaft of the hydraulic cylinder 217 is fixedly connected to the driving upper die seat 214. The driving upper die seat 214 is lifted and lowered by controlling the telescopic shaft of the hydraulic cylinder 217 to extend and retract, so that the cardboard is compressed and molded by closing the compression lower die 205 and the compression upper die 206.

[0049] Specifically, the hydraulic cylinder 217 is commercially available and can be purchased and used directly.

[0050] like Figures 1 to 3 As shown, a pair of pneumatic unloading mechanisms 3 are fixedly assembled on both sides of the frame 1, and the pneumatic unloading mechanism 3 includes an air pipe fixing frame 301, and the air pipe fixing frame 301 is fixedly assembled above the auxiliary workbench 201. The air pipe fixing frame 301 supports and fixes the conductive air pipe 302, thereby improving the running stability of the conductive air pipe 302.

[0051] like Figures 1 to 3 As shown, a conducting air pipe 302 is hinged on the upper side of the air pipe fixing frame 301. The conducting air pipe 302 plays the role of assembling and fixing the multiple air nozzles 303 and conducting the gas. The conducting air pipe 302 is fixedly assembled with multiple groups of evenly distributed air nozzles 303 on one side close to the lower mold support plate 202, and the air nozzles 303 are arranged corresponding to the compression lower mold 205. It is convenient to perform auxiliary unloading and pneumatic cleaning of the paper tray supported on the compression lower mold 205 by spraying compressed gas to the compression lower mold 205 through the multiple air nozzles 303.

[0052] like Figures 1 to 3 As shown, a connecting air pipe 304 is fixedly connected to one side of the venting pipe 302 away from the air nozzle 303. It is convenient to transport compressed gas into the venting pipe 302 through the connecting air pipe 304, so as to provide compressed gas for multiple groups of air nozzles 303.

[0054] When in use, a pair of compression lower dies 205 are assembled on a pair of lower die support plates 202, and a compression upper die 206 is assembled on the bottom of the driving upper die seat 214. Subsequently, during operation, the pair of compression lower dies 205 maintains a single set of compression lower dies 205 and compression upper die 206, and the cardboard to be compressed is placed on the compression lower die 205 below the protective cover shell 212. Subsequently, the operation of the stepper motor 211 is controlled to drive the lead screw 204 to rotate, and the lead screw slider 203 drives the lower die support plate 202 to move under the action of the internal and external threads, and the compression lower die 205 is moved to the bottom of the compression upper die 206 through the rotation of the lead screw 204.

[0055] When the paper pallet is compressed and formed, the compression lower mold 205 and the compression upper mold 206 are separated by controlling the retraction of the telescopic shaft of the hydraulic cylinder 217. After separation, the operation of the stepper motor 211 is controlled to separate the compression lower mold 205 supporting the paper pallet from the compression upper mold 206 by sliding.

[0056] Meanwhile, during the compression process of the single group of compression lower mold 205 and the compression upper mold 206, the other group of compression lower mold 205 is located below the protective cover shell 212. The operator can unload and discharge the compression lower mold 205 in the protective cover shell 212.

[0057] In addition, by connecting the air pipe 304 to an external compressed air pipe, multiple groups of air nozzles 303 can spray compressed gas toward the compression lower mold 205 in the protective cover shell 212. By spraying compressed gas, the paper pallet compressed in the compression lower mold 205 can be pneumatically unloaded and blown clean, thereby improving the efficiency and safety of the paper pallet production compression device.
