Description

Technical field:

[0001] The utility model relates to the technical field of mold transfer, in particular to an automatic conveying and unloading machine for ultra-high molecular weight polyethylene molds. Background technology:

[0002] At present, ultra-high molecular weight polyethylene sheets have been widely used in metallurgy, electric power, coal mining, shipbuilding, papermaking, textile and other industries due to their ultra-high wear resistance, excellent impact resistance and corrosion resistance. In the production process of ultra-high molecular weight polyethylene sheets, new ultra-high molecular weight polyethylene raw materials are required, and they are molded by hot presses and cold presses. At present, when the molds are transported between the hot press and the cold press, workers usually operate the crane to carry them. The degree of automation is low, and workers manually load and unload the molds, which has low work efficiency, poor positioning accuracy, poor stability of the crane, and is prone to accidents such as collisions and falls, thus affecting production safety.

[0003] In summary, the problem of transferring ultra-high molecular weight polyethylene molds between hot presses and cold presses has become a technical problem that needs to be solved urgently in the industry. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model provides an automatic transport and unloading machine for ultra-high molecular weight polyethylene moulds, which solves the problems of low automation, low efficiency and poor stability during previous crane transport.

[0009] The translation grab is movably hoisted on the track of the lifting beam, and a translation oil cylinder connected with the translation grab is installed at the bottom of the lifting beam.

[0011] The cross brace cooperates with the edge of the mold to support the mold.

[0012] The electromagnetic suction cup is used for electromagnetically adsorbing the metal cover plate of the mold.

Specific implementation method:

[0020] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, an automatic handling and unloading machine for ultra-high molecular weight polyethylene molds includes a fixed frame 4 installed above a mold inlet and outlet device 3 of a hot press 1 and a cold press 2, a movable frame 5 is installed on the top of the fixed frame 4, and the movable frame 5 can be moved along a guide rail to above the mold inlet and outlet device 3 of the hot press 1 or the cold press 2, at least two lifting beams 6 are installed on the movable frame 5 in parallel and at intervals, and a translation gripper 7 is movably installed at both ends of each lifting beam 6, a negative pressure suction cup 8 and an electromagnetic suction cup 9 are provided at the bottom of the translation gripper 7, a cross brace 10 is provided on the inner side of the translation gripper 7, and an anti-drop mechanism 11 is provided on the outer side of the translation gripper 7.

[0022] Traveling motors 12 are respectively installed at both ends of the mobile frame 5, and gears are installed on the output shaft of the traveling motor 12, and the gears are meshed with the racks provided on the fixed frame 4. A guide rail is provided on the top of the fixed frame 4, and a running wheel matched with the guide rail is provided at the bottom of the mobile frame 5. When the traveling motor 12 is working, the gears are driven to rotate, and since the gears are meshed with the racks on the fixed frame 4, the mobile frame 5 will move along the guide rail on the fixed frame 4 through the running wheels at the bottom.

[0023] The middle part of the lifting beam 6 is connected to the lifting cylinder 13 installed on the moving frame 5, and the two sides of the lifting beam 6 are respectively provided with guide shafts 14 that slide with the moving frame 5. The lifting cylinder 13 can drive the lifting beam 6 to move up and down, and the guide shaft 14 will guide the lifting beam 6 to move up and down.

[0024] The translation gripper 7 is movably hoisted on the track of the lifting beam 6, and a translation cylinder 15 connected to the translation gripper 7 is installed at the bottom of the lifting beam 6. The translation cylinder 15 can drive the translation gripper 7 to move left and right along the track of the lifting beam 6, and the same function can also be achieved by replacing the translation cylinder 15 with a motor screw structure.

[0025] The anti-drop mechanism 11 includes a lifting seat 17 movably mounted on the guide column 16 outside the translation gripper 7, the top of the lifting seat 17 is connected to the lifting cylinder 18 mounted on the translation gripper 7, the bottom of the lifting seat 17 is installed with a rotating cylinder 19, and the bottom of the rotating cylinder 19 is installed with a supporting arm 20. The lifting cylinder 18 can drive the lifting seat 17, the rotating cylinder 19 and the supporting arm 20 to move up and down to adjust the up and down distance, and the rotating cylinder 19 can drive the supporting arm 20 to rotate 90 degrees, so that the supporting arm 20 is supported on the bottom of the mold or the ultra-high molecular weight polyethylene plate, which plays a protective role and prevents falling.

[0026] The cross brace 10 cooperates with the edge of the mold to support the mold, and the entire mold can be carried.

[0027] The electromagnetic suction cup 9 is used to electromagnetically absorb the metal cover plate of the mold, so that the metal cover plate of the mold can be moved.

[0028] The negative pressure suction cup 8 is used to vacuum absorb the ultra-high molecular weight polyethylene sheet in the mold, and the ultra-high molecular weight polyethylene sheet can be transported.

[0029] Working principle:

[0030] During operation, the ultra-high molecular weight polyethylene raw material is first spread in the mold, covered with a metal cover plate, placed on the in-and-out mold device 3 and sent to the hot press 1. After the ultra-high molecular weight polyethylene raw material and the mold complete the hot pressing process in the hot press 1, the in-and-out mold device 3 transports the mold out of the hot press 1. Then the travel motor 12 is controlled to move the mobile frame 5 to the top of the mold, the lifting cylinder 13 is controlled to drive the lifting beam 6 to descend, and then the translation cylinder 15 is controlled to drive the translation gripper 7 to move horizontally, so that the cross brace 10 of the translation gripper 7 supports the edge of the mold, and then the lifting cylinder 13 is controlled to drive the lifting beam 6 to rise, and the travel motor 12 is controlled to move the mobile frame 5 to the top of the in-and-out mold device 3 of the cold press 2, and the mold is put down. The in-and-out mold device 3 drives the mold and the ultra-high molecular weight polyethylene plate into the cold press 2 for cold pressing. When the cold pressing process is completed, the mold entry and exit device 3 transports the mold out again. At this time, the mold unloading work is required. The lifting cylinder 13 is also controlled to drive the lifting beam 6 to descend, and then the translation cylinder 15 is controlled to drive the translation gripper 7 to move horizontally, so that the electromagnetic suction cup 9 of the translation gripper 7 electromagnetically adsorbs the metal cover plate of the mold, removes and places the metal cover plate, and then repeats the operation to make the negative pressure suction cup 8 of the translation gripper 7 vacuum adsorb the ultra-high molecular weight polyethylene plate in the mold, and move the ultra-high molecular weight polyethylene plate to the placement position. In the process of moving the mold, metal cover plate and ultra-high molecular weight polyethylene plate, the lifting cylinder 18 and the rotating cylinder 19 of the anti-drop mechanism 11 can be operated to rotate the support arm 20 90 degrees to support the bottom of the mold, metal cover plate or ultra-high molecular weight polyethylene plate to play a protective role and prevent it from falling.

For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
