Description

Technical Field

[0001] The utility model belongs to the technical field of lead ingot production lines, and particularly relates to a scale calibration system for a weighing platform for stacking lead ingots in a lead ingot production line. Background Art

[0002] Weighing the stacks of lead ingots is an essential step in the lead ingot production process at nonferrous metal processing plants. Before entering storage, the ingots must be weighed on a scale, and the result printed on a label serves as a crucial basis for both warehousing and sales. In most nonferrous metal processing plants, calibration of the scales on the lead ingot production line is performed manually by hoisting calibration weights onto the scales using a crane. This operation requires at least two people (one to operate the crane, the other to attach the weights to the crane's hoist), which is time-consuming and impacts the overall production line's tempo. Furthermore, manual operation poses safety risks. Summary of the Invention

[0003] The utility model aims to solve the problem that the calibration work of the weighing platform on the existing lead ingot production line is manually performed by using a crane to lift the calibration weight to the weighing platform for calibration. This operation mode not only requires the participation of at least two people and takes a long time, but also has safety hazards due to manual participation. The utility model provides a calibration system for the weighing platform for stacking lead ingots in the lead ingot production line. The system moves a moving component until the fork is located under the calibration weight, and then the oil cylinder drives the fork to move upward to pick up the calibration weight. Then the moving component is reset to drive the calibration weight to move above the weighing platform, and the oil cylinder drives the calibration weight to be placed on the support rod on the weighing platform, thereby reducing manual participation.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A calibration system for a weighing platform for stacked lead ingots on a lead ingot production line comprises a stand and a first bracket and a second bracket symmetrically arranged below the stand. The stand is provided with a moving assembly, the first bracket is provided with a calibration weight, and the second bracket is provided with a weighing platform. The weighing platform is calibrated by the calibration weight.

[0006] A slide rail and a rack are provided at the upper end of the stand, and the moving assembly is slidably provided on the slide rail. A motor is fixedly provided above the moving assembly, and the output end of the motor passes through the moving assembly and is fixedly connected to a gear, and the gear is engaged with the rack. The motor drives the gear to rotate, and the engagement of the gear and the rack drives the moving assembly to move.

[0007] An oil cylinder and a vertical track are fixedly provided on the lower side of the moving component. A lifting plate is fixedly connected to the output end of the oil cylinder. The lifting plate is connected to the vertical track for sliding up and down. Two insertion rods are fixedly provided on one side of the lifting plate for supporting the calibration weights. The oil cylinder drives the lifting plate to rise and fall, and drives the fork to rise and fall.

[0008] Preferably, the stand includes a plurality of columns, a support frame is fixedly arranged above the plurality of columns, a slide rail is arranged above two cross bars arranged opposite to each other in the support frame, and a rack is arranged on one side of one cross bar facing the other cross bar, and the support frame is supported by the columns.

[0009] Preferably, a plurality of support rods are fixedly provided above the first bracket and the weighing platform, and there is a gap between two adjacent support rods. The plurality of insertion rods respectively correspond to the gaps between the plurality of support rods and pass through the corresponding gaps, so that the movement of the fork is not interfered by the support rods.

[0010] Preferably, the insertion rod is L-shaped, the vertical rod of the L-shaped insertion rod is fixedly connected to the lifting plate, and the horizontal rod is located below the lifting plate. The vertical rod of the L-shaped insertion rod is fixedly connected to the lifting plate to ensure that the fork is installed firmly.

[0011] Preferably, the cross-sections of the slide rail and the vertical rail are both T-shaped, the moving component is slidably matched with the slide rail, and the hanging plate is slidably matched with the vertical rail. The T-shaped rail ensures that the moving component and the hanging plate are slidably connected, and limits them to prevent them from leaving the track.

[0012] Preferably, a reinforcing rod is fixedly provided between the upper end of the vertical track and the lower side of the moving assembly to ensure the overall structural strength when the lifting plate drives the calibration weight to move.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] 1. The utility model uses a motor and a cylinder to drive the calibration weight to lift the calibration weight and work on the weighing platform. Compared with the existing technology that requires two people to complete the work, the labor intensity of manual work is greatly reduced and the work efficiency is effectively improved.

[0015] 2. The utility model realizes the transportation of the calibration weights by lifting the calibration weights with an inserted rod, thereby ensuring the stability of the calibration weights during transportation and facilitating the positioning of the calibration weights during lifting and placing them on the weighing platform.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 4 As shown, this embodiment provides a scale calibration system for a lead ingot production line to weigh lead ingots in stacks, comprising a stand 1 and a first bracket 2 and a second bracket 3 symmetrically arranged below the stand 1, a slide rail 7 and a rack 8 being arranged on the upper end of the stand 1, the stand 1 comprising a plurality of columns, a support frame being fixedly arranged above the plurality of columns, the support frame being a rectangular rod structure, the columns being arranged in four and respectively located at the lower sides of the four corners of the support frame, a fixed rod being fixedly connected between two adjacent columns, the first bracket 2 and the second bracket 3 being respectively located below the two ends of the support frame, the support frames being arranged relatively A slide rail 7 is provided above each of the two cross bars, and a rack 8 is provided on one side of the cross bar facing the other cross bar. A moving component 4 is provided on the vertical frame 1, and the moving component 4 is slidably set on the slide rail 7. The moving component 4 is slidably set on the support frame through the slide rail 7. A motor 9 is fixedly provided above the moving component 4, and the output end of the motor 9 passes through the moving component 4 and is fixedly connected to a gear 10, the gear 10 is engaged with the rack 8, and the motor 9 drives the gear 10 to rotate, and the gear 10 is engaged with the rack 8, so the rotation of the gear 10 drives the moving component 4 to slide along the slide rail 7.

[0023] A calibration weight 5 is provided on the first bracket 2, and a weighing platform 6 is provided on the second bracket 3. A plurality of support rods 15 are fixedly provided above the first bracket 2 and the weighing platform 6. There is a gap between two adjacent support rods 15, and the calibration weight 5 is placed above the corresponding support rod 15.

[0024] The lower side of the moving component 4 is fixedly provided with an oil cylinder 11 and a vertical rail 12, and the output end of the oil cylinder 11 is fixedly connected to a lifting plate 13, and the oil cylinder 11 drives the lifting of the lifting plate 13, and the lifting plate 13 is connected to the vertical rail 12 for sliding up and down. The vertical rail 12 is used to limit the up and down sliding of the lifting plate 13 to ensure that the lifting plate 13 can only move up and down. Two insertion rods 14 are fixedly provided on one side of the lifting plate 13 for supporting the calibration weight 5, and the insertion rod 14 is L-shaped, and the vertical rod of the L-shaped insertion rod 14 is fixedly connected to the lifting plate 13, and the horizontal rod is located below the lifting plate 13. The lifting of the lifting plate 13 drives the insertion rod 14 to lift and lower the objects above the insertion rod 14, and then picks up or puts down the objects above the insertion rod 14.

[0025] The cross-sections of the slide rail 7 and the vertical rail 12 are both T-shaped, the moving component 4 slides and matches with the slide rail 7, and the hanging plate 13 slides and matches with the vertical rail 12. The T-shaped slide rail 7 and the vertical rail 12 ensure that the moving direction of the moving component 4 and the hanging plate 13 is limited while avoiding derailment.

[0026] A reinforcing rod 16 is fixedly provided between the upper end of the vertical rail 12 and the lower side of the moving assembly 4 , and the reinforcing rod 16 ensures the connection strength between the vertical rail 12 and the moving assembly 4 .

[0027] The working principle of the present utility model is as follows: in the initial state, the insertion rod 14 is located in the gap between the corresponding support rods 15 above the second bracket 3;

[0028] When calibrating the weighing platform 6, first start the motor 9, and the motor 9 drives the gear 10 to rotate. Since the gear 10 is engaged with the rack 8, the gear 10 rotates and drives the moving component 4 to move toward the first bracket 2. When it moves to the gap between the multiple support rods 15 above the first bracket 2, it stops moving. At this time, the rod 14 is located above the first bracket 2 and the calibration weight 5 is placed below. Then start the cylinder 11, drive the lifting plate 13 to drive the rod 14 to rise, and then pick up the calibration weight 5. The motor 9 drives the gear 10 to rotate in the opposite direction, and then the moving component 4 moves in the opposite direction and resets. When the belt moves to the weighing weight 5 and is located above the weighing platform 6, the motor 9 stops working, and the cylinder 11 drives the lifting plate 13 and the rod 14 to move downward, and then the calibration weight 5 is placed on the weighing platform 6, and the weighing platform 6 is calibrated.

[0029] After completing the calibration work, lift the calibration weight 5 and put it back on the first bracket 2 (this process is similar to the above process, so it will not be repeated here).

[0030] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
