Description

Technical Field

[0001] The invention relates to the field of aluminum ingot production equipment, and more specifically to an automatic weighing and drying device for aluminum ingot stacks. Background Art

[0002] Aluminum ingots are important raw materials for manufacturing aluminum products and are suitable for long-term storage and transportation. In the process of producing aluminum ingots, the continuously produced aluminum ingots are generally stacked together regularly by stacking and stacking robots to form aluminum ingot stacks, and then the processes of offline and weighing are carried out. The weighing of aluminum ingot stacks usually uses a forklift to move the aluminum ingot stacks ready to be offline to the electronic scale for weighing, and then send the aluminum ingot stacks back to the ingot drying line or warehouse. During the process of offline and weighing the aluminum ingot stacks, it is not only inefficient but also wastes manpower and production space to move the aluminum ingot stacks to a designated location for weighing. For example, the invention patent with patent number CN200710010590.6 discloses an aluminum ingot continuous casting unit.

[0003] The automatic weighing device for aluminum ingot stacks is an automated device that measures the weight of aluminum ingot stacks before they come off the production line, which improves the weighing efficiency of aluminum ingot stacks and saves production space. The existing automatic weighing device for aluminum ingot stacks lifts up the aluminum ingot stacks placed on two rectangular tubes for weighing by raising the weighing pallet arranged between two chains. The maximum vertical distance between the two chains is greater than the width of the aluminum ingot stack. The forklift driver forks the aluminum ingot stack from one side of the ingot drying transport line. For example, the utility model patent with patent number CN201921001091.5 discloses an online weighing device.

[0004] The existing automatic weighing and drying ingot transport line equipment for aluminum ingot stacks has problems such as interference between rectangular tubes and weighing pallets, large floor space occupied by the drying ingot line and easy wear of the chain: two rectangular tubes are screwed on the chain links, and the position of the aluminum ingot stack is fixed accordingly. The accumulated rotation error of the chain causes the two rectangular tubes to deviate from the designated weighing position; the drying ingot line is wide, wasting production space; when a forklift picks up a stack of aluminum ingots from one side of the drying ingot line, the fork contacts the chain and causes wear. Summary of the invention

[0005] The purpose of the present invention is to solve the problems of interference between rectangular tubes and weighing pallets, large floor space occupied by the ingot drying line and easy wear of chains in the existing automatic weighing and drying ingot transport line equipment for aluminum ingot stacks.

[0006] In the improved solution, the transmission chain includes chain plates, rectangular tubes, bolts and rollers; the rectangular tubes are fixed to the chain plates by two bolts, and multiple rectangular tubes cover all the chain plates.

[0007] In the improved solution, the other end of the frame includes a transmission chain protection plate, a gear, an angle joint plate and a chain rail; the transmission chain protection plate is welded to the frame through a pad, the motor drives the gear to rotate, and drives the transmission chain to rotate synchronously, an angle joint plate is welded on the frame, and a chain rail is welded on the angle joint plate, which passes through the entire frame, and the chain rail supports the rollers of the transmission chain.

[0008] In the improved solution, there are two stacking photoelectric switches at the lower side of the anti-tilt plate of the aluminum ingot stack, and there is an aluminum ingot stack above; the aluminum ingot stack consists of foot ingots and aluminum ingots; and there is an electrical circuit protection tube under the angle joint plate.

[0009] In the improved scheme, the weighing photoelectric switch is located at the top of the automatic weighing device, and also includes a weighing base at the bottom, the weighing module is screwed between the weighing base and the weighing frame, the cylinder is screwed between the weighing frame and the load-bearing frame, the linear bearing and the guide rod are screwed with the weighing frame and the load-bearing frame respectively, the guide rod is arranged in the linear bearing, the load-bearing pillar is screwed on the load-bearing frame, the weighing support plate and the weighing photoelectric switch bracket are both welded to the load-bearing pillar, and the weighing photoelectric switch is screwed on the weighing photoelectric switch bracket; the stable photoelectric switch baffle mounting column and the stable photoelectric switch bracket are respectively welded to the load-bearing frame and the weighing frame, the stable photoelectric switch is screwed on the stable photoelectric switch bracket, and the stable photoelectric switch baffle is welded on the stable photoelectric switch baffle mounting column.

[0010] The technical effects achieved by the present invention are as follows:

[0011] 1. Move the weighing plate between the two transmission chains to the outside of the two transmission chains to avoid the problem of interference between the rectangular tube on the transmission chain and the weighing plate.

[0012] 2. The rectangular tubes are spread all over the transmission chain, the aluminum ingot stack is rotated 90°, the lower length of the foot ingot is shortened, the width of the ingot drying line is reduced, and the production space is saved.

[0013] 3. Change the method of forking aluminum ingots by forklift from the side of the drying line to one end of the drying line, and install a transmission chain protection plate to avoid wear caused by contact between the forklift fork and the transmission chain.
