Description

Technical Field

[0001] The utility model belongs to the technical field of battery preparation, and in particular relates to an automatic punching and feeding device for zinc sheets. Background Art

[0002] In the nine-volt stacked carbon battery, each unit layer of the battery has a zinc sheet to meet the needs of the battery chemical reaction. The zinc sheet is a rectangular sheet with smooth transitions at the four corners. It is composed of a zinc plate and a conductive film layer and a starch paper layer bonded to the upper and lower surfaces of the zinc plate. It is usually punched by a multi-station forming mold in a step-by-step drawing method. Since the zinc sheet accounts for a large proportion of the production cost of the nine-volt stacked battery, how to save the raw materials of the zinc sheet, reduce the labor intensity of workers, improve production efficiency, and reduce production costs are issues that most manufacturers are concerned about.

[0003] like Figure 1 As shown, it is a multi-station punching arrangement of zinc sheets in the prior art. First, the whole roll of raw material zinc sheet is placed on the rotating shaft of the unloading rack, and its free end passes through the punching equipment and the stepping puller and is then wound on the rotating shaft of the waste collection rack. The punching equipment includes a press and a plurality of zinc sheet forming molds, and the forming molds include upper and lower dies that cooperate with each other. The stepping pulling method is adopted during punching, that is, the stepping puller at the rear end of the forming mold is driven to rotate intermittently through the up and down movement of the slider of the press, so that the raw material zinc sheet at the front end of the forming mold is horizontally stepped on the punching equipment, and the press is controlled to push the upper punch to intermittently move downward and the fixed lower punch to punch the raw material zinc sheet, so as to punch out the required zinc sheet. In order to ensure that the positions of the zinc sheets punched each time do not overlap, it is necessary to control the stepping interval of the zinc sheet on the punching equipment so that the interval between the zinc sheets punched each time is 0.8-1.2mm, such as Figure 1 The figure shows the schematic diagram of the waste of raw material zinc plate after punching by the existing process technology. The utilization rate of the raw material zinc plate is not high, only about 84%, and the remaining about 16% of the unpunched edge material will be wasted as edge waste, resulting in high production costs. Utility Model Content

[0004] In view of the above-mentioned technical problems, the utility model provides an automatic zinc sheet punching and feeding device to solve the problem of material waste in the existing zinc sheet punching. The utilization rate of the plate material of the automatic zinc sheet punching and feeding device can reach more than 97%, and the utilization rate is effectively improved.

[0005] The utility model provides a zinc sheet automatic punching feeding device, comprising a feeding mechanism, an upper die mechanism, a lower die mechanism, a sheet feeding mechanism and a limit block, wherein the feeding mechanism and the sheet feeding mechanism are respectively arranged at the two ends of the lower die mechanism, the upper die mechanism can be raised and lowered above the lower die mechanism, limit plates are arranged in parallel on both sides of the top of the lower die mechanism, the lower die mechanism is respectively provided with lower blade edges at positions adjacent to the two limit plates, the upper die mechanism is respectively provided with upper knives at positions corresponding to the two lower blade edges, and the two upper knives face each other. The side surface is a V-shaped structure with a cross section composed of two arc-shaped surfaces. The shape of the lower blade is adapted to the shape of the upper blade. The sheet feeding mechanism includes a material trough, a sheet feeding cylinder and a push ruler. The material trough is located between the limit block and the lower die mechanism, and the width of the material trough is consistent with the width of the zinc sheet to be punched. A slicing lower tool is provided on one side of the material trough adjacent to the lower die mechanism, and an upper slicing tool is provided on the upper die mechanism corresponding to the position of the slicing lower tool. The push ruler is slidably arranged in the material trough, and the sheet feeding cylinder is connected to the push ruler.

[0006] Furthermore, the feeding mechanism includes a feeding motor, an upper rotating roller and a lower rotating roller, the upper rotating roller and the lower rotating roller are arranged with an upper and lower interval, and the feeding motor is connected to the lower rotating roller.

[0007] Furthermore, the upper mold mechanism is provided with a pressure rod, and the pressure rod is connected to a side of the slicer tool close to the material trough.

[0008] Furthermore, the upper die mechanism is connected to a punching cylinder.

[0009] Compared with the existing zinc sheet punching device, this zinc sheet automatic punching and feeding device has the following advantages:

[0010] 1. The utilization rate of the improved zinc sheet automatic punching feeding device for the sheet can reach more than 97%, while the utilization rate of the existing forming mold zinc sheet punching for the sheet is only about 84%, and the utilization rate has been greatly improved. 2. The use of relatively narrow raw material zinc sheet punching effectively solves the distortion and deformation of the sheet itself, and the quality of the punched zinc sheet is also guaranteed. 3. There is no need for presses, forming molds, pullers, waste racks and special material frames to load zinc sheets, which reduces the space and energy consumption required for the equipment, reduces the labor intensity of workers, reduces production costs, and generates significant economic benefits.

[0017] The utility model discloses an automatic zinc sheet punching and feeding device. The utilization rate of the plate material of the automatic zinc sheet punching and feeding device can reach more than 97%, and the utilization rate is effectively improved.

[0018] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, what is described is only a part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figures 2 to 5As shown, the utility model discloses an automatic punching and feeding device for zinc sheets, comprising a feeding mechanism, an upper die mechanism 1, a lower die mechanism 13, a sheet feeding mechanism and a limit block 5, wherein the feeding mechanism and the sheet feeding mechanism are respectively arranged at two ends of the lower die mechanism 13, the upper die mechanism 1 can be raised and lowered above the lower die mechanism 13, and limit plates 14 are arranged in parallel on both sides of the top of the lower die mechanism 13, the lower die mechanism 13 is respectively provided with lower blades 10 at positions adjacent to the two limit plates 14, and the upper die mechanism 1 is respectively provided with upper knives 7 at positions corresponding to the two lower blades 10, and the two upper knives 7 face each other. The side surface is a V-shaped structure with a cross section composed of two arc-shaped surfaces. The shape of the lower blade 10 is adapted to the shape of the upper blade 7. The sheet feeding mechanism includes a material trough 6, a sheet feeding cylinder 11 and a push ruler 15. The material trough 6 is located between the limit block 5 and the lower die mechanism 13, and the width of the material trough 6 is consistent with the width of the zinc sheet to be punched. A slicing lower tool 4 is provided on the side of the material trough 6 adjacent to the lower die mechanism 13, and a slicing upper tool 2 is provided on the upper die mechanism 1 corresponding to the position of the slicing lower tool 4. The push ruler 15 is slidably arranged in the material trough 6, and the sheet feeding cylinder 11 is connected to the push ruler 15.

[0020] The feeding mechanism comprises a feeding motor 12 , an upper rotating roller 8 and a lower rotating roller 9 . The upper rotating roller 8 and the lower rotating roller 9 are arranged with an interval up and down, and the feeding motor 12 is connected to the lower rotating roller 9 .

[0021] The upper mold mechanism 1 is provided with a pressure rod 3 , and the pressure rod 3 is connected to a side of the slicing upper tool 2 close to the material trough 6 .

[0022] The upper die mechanism 1 is connected with a punching cylinder.

[0023] When punching zinc sheets, the operator first places the whole roll of raw material zinc sheet on the rotating shaft of the unwinding rack, and its free end passes between the upper rotating roller 8 and the lower rotating roller 9, and is introduced into the entrance of the limit plate 14. Then the punching cylinder drives the entire upper die mechanism 1 to move up and down. When the punching upper die leaves the limit plate 14 during upward movement, the feeding mechanism presses the zinc sheet for linear horizontal transportation. When it moves downward, the feeding mechanism stops working. In this way, the zinc sheet is gradually transported to the working position of the upper knife 7 and the lower knife edge 10 in an intermittent stepping manner. Since the two sides of the upper knife 7 facing each other are a V-shaped structure composed of two arc-shaped surfaces, the upper knife 7 and the lower knife edge 10 are 10 can punch out the rounded corners of two adjacent zinc sheets at the same time, and the punched edge material is discharged along the lower blade 10. Each time the zinc plate punches out the rounded corners, the feeding mechanism will step and horizontally convey the width of a zinc sheet. After punching out several rounded corners of zinc sheets, the connection between the first two adjacent zinc sheets is exactly consistent with the edge position of the upper slicing cutter 2 and the lower slicing cutter 4. When punching out again, the upper slicing cutter 2 and the lower slicing cutter 4 simultaneously cut out the formed zinc sheet, and the formed zinc sheet is pressed down by the pressing rod 3 and sent to the material trough 6. The formed zinc sheet in the material trough 6 is finally pushed directly into the required "shrink sleeve" by the push ruler 15 for the next step of making the rubber cup. In this way, the automatic punching and feeding process of the entire zinc sheet is completed.
