Description

Technical Field

[0001] This application relates to the technical field of sheet processing, and in particular to a feeding device for sheet production. Background Technology

[0002] A fuse is an important electrical protection device used to protect electrical equipment from damage caused by overcurrent or short-circuit current. One of its core components is the fuse element, also known as the fuse core or fuse body, which is the key part of the fuse to achieve its protective function. When the current exceeds its rated value, the fuse element will expand due to heat and eventually melt, thereby breaking the circuit and preventing damage to the electrical equipment.

[0003] In related technologies, the precise pre-cutting of metal strips into uniformly sized sheets is a crucial first step in sheet processing. This step not only affects the smoothness and efficiency of the entire production process but also directly determines whether the final product can meet the predetermined performance standards and appearance quality.

[0004] However, it is worth noting that metal strips often have some bending or surface unevenness before entering the cutting process due to improper storage, transportation, or pre-treatment. If these potential problems are not properly addressed, they will directly and adversely affect the cutting accuracy and the flatness of the sheet material, thereby increasing the difficulty of subsequent processing steps such as bending and punching. Ultimately, this may lead to a significant decrease in the pass rate of the finished sheet, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a feeding device for sheet production, which solves the problem in the above-mentioned related technologies that the metal strip may have a certain degree of bending or unevenness before cutting, which affects the subsequent finished product qualification rate.

[0006] The technical solution of the feeding device for sheet production provided in this application is as follows:

[0007] A feeding device for producing sheet metal includes a base and a feeding plate fixed on the base. The feeding plate is rotatably equipped with a feeding wheel for winding metal strip. The feeding plate is also equipped with a traction assembly and a cutting assembly. The traction assembly includes a traction plate located above the feeding plate, a traction cylinder for moving the traction plate toward the cutting assembly, and a clamping member located on the traction plate for clamping the metal strip. The clamping member includes a clamping plate located above the traction plate and a clamping cylinder for reciprocating the clamping plate toward the upper surface of the traction plate.

[0008] By adopting the above technical solution, during the metal strip feeding process, the metal strip is pre-wound around the outer circumference of the feed wheel and passes between the traction plate and the clamping plate. When feeding is required, the clamping cylinder is activated to move the clamping plate, thereby clamping the metal strip between the traction plate and the clamping plate. Then, the traction cylinder is activated to move the traction plate and the clamping plate as a whole away from the feed wheel, thus realizing the feeding of the metal strip. During the clamping and clamping process of the clamping plate and the traction plate, the uneven surface of the metal strip can be flattened, thereby reducing the problem of low yield rate of subsequent sheet processing due to uneven surface of the metal strip and improving the yield rate of subsequent sheet processing.

[0009] Optionally, a fixing frame is fixedly provided on the upper side of the feed plate, and a tension roller is rotatably mounted on the fixing frame.

[0010] By adopting the above technical solution, due to the coordinated arrangement of the fixed frame and the tensioning roller, the tensioning roller is used to tension the metal strip during the feeding process. The tensioning roller applies appropriate tension to ensure that the metal strip remains taut during the feeding process, effectively preventing the metal strip from loosening due to gravity or other factors. Stable tension can reduce the deformation and twisting of the metal strip during the processing, thereby improving the processing accuracy during subsequent cutting.

[0011] Optionally, a receiving plate is fixed on the side of the fixing frame away from the feed plate, and the traction electric cylinder is fixed on the bottom side of the receiving plate.

[0012] By adopting the above technical solution, the traction electric cylinder can be supported due to the setting of the receiving plate.

[0013] Optionally, the side of the receiving plate away from the feed plate is flush with the side of the traction plate away from the feed plate, and a through gap is provided between the receiving plate and the tension roller.

[0014] By adopting the above technical solution, since the upper surfaces of the receiving plate and the traction plate are flush, the metal strip can slide along the upper surface of the receiving plate after passing through the gap during the feeding process, thereby reducing the possibility of fluctuation or deviation of the metal strip during the feeding process and improving the stability of the metal strip during the feeding process.

[0015] Optionally, limiting strips for limiting the clamping plate are fixed on the two opposite sides of the upper side of the traction plate.

[0016] By adopting the above technical solution, the upper limit bar of the traction plate limits the sliding metal strip on the traction plate, reducing the possibility of the metal strip shifting or misaligning during the feeding process.

[0017] Optionally, a support frame is fixedly provided on the upper side of the feed plate, and the cutting assembly includes a cutting cylinder fixedly provided on the support frame and a fixing plate fixedly provided on the end of the moving rod of the cutting cylinder; a cutting blade is fixedly provided on the side of the fixing plate facing the feed plate, and a cutting plate is fixedly provided on the side of the support frame, and a cutting groove is provided on the cutting plate located directly below the cutting blade.

[0018] By adopting the above technical solution, when the metal strip is fed to the bottom of the cutting blade, the cutting cylinder is activated to drive the fixed plate and the cutting blade to move towards the cutting groove, thereby realizing the cutting of the metal strip and facilitating subsequent processing.

[0019] Optionally, the fixing plate is provided with an elastic abutment, which includes a telescopic rod fixed to the side of the fixing plate facing the cutting plate and a compression spring located inside the telescopic rod, and an abutment block is fixed to the end of the telescopic rod facing the cutting plate.

[0020] By adopting the above technical solution, when the cutting blade cuts the metal strip, the compression spring is in a compressed state due to the cooperation of the elastic abutment component, so that the bottom side of the abutment block presses against the metal strip on the cutting plate, which can play a pre-pressing role and reduce the possibility of the metal strip shifting or misaligning during cutting; when the cutting blade is reset, the telescopic rod moves synchronously away from the cutting plate, and in the reset state, there is a gap between the bottom side of the abutment block and the upper side of the cutting plate.

[0021] Optionally, limiting protrusions are fixed on the two opposite sides of the upper side of the cutting plate.

[0022] By adopting the above technical solution, the metal strip on the cutting plate is limited by the setting of the limiting protrusion, which further reduces the possibility of the metal strip shifting or misaligning during cutting.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the clamping and traction process, the uneven surface of the metal strip can be flattened, thereby reducing the problem of low pass rate of subsequent sheet processing due to uneven surface of the metal strip and improving the pass rate of subsequent sheet processing.

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] Example:

[0035] Reference Figure 1 and Figure 2 A feeding device for producing molten sheet includes a base 1 and a feeding plate 2 fixed on the base 1, wherein a feeding wheel 21 for winding metal strip is rotatably arranged on the feeding plate 2, and a traction component 3 and a cutting component 4 are arranged on the feeding plate 2.

[0036] During the metal strip feeding process, the metal strip is pre-wound around the outer circumference of the feed wheel 21, and then the traction component 3 drives the metal strip to feed towards the cutting component 4.

[0037] Reference Figure 3A fixed frame 22 is fixed on the upper side of the feed plate 2, and a tension roller 23 is rotatably mounted on the fixed frame 22. A receiving plate 24 is fixed on the side of the fixed frame 22 away from the feed plate 2, and a through gap is provided between the receiving plate 24 and the tension roller 23. During the process of being pulled and fed by the traction component 3, the metal strip first wraps around the tension roller 23 and adheres to the upper surface of the receiving plate 24 along the through gap, and then feeds along the upper surface of the receiving plate 24.

[0038] Reference Figure 3 and Figure 4 The traction assembly 3 includes a traction plate 31 located above the feed plate 2, a traction electric cylinder 32 for driving the traction plate 31 to reciprocate towards the cutting assembly 4, and a clamping member 33 disposed on the traction plate 31 for clamping the metal strip. The traction electric cylinder 32 is fixed on the bottom side of the receiving plate 24, and the side of the receiving plate 24 away from the feed plate 2 is flush with the side of the traction plate 31 away from the feed plate 2.

[0039] The clamping member 33 includes a clamping plate 331 located above the traction plate 31 and a clamping cylinder 332 that drives the clamping plate 331 to reciprocate towards the upper surface of the traction plate 31. The upper side of the traction plate 31 is fixed with two opposite side edges for limiting the clamping plate 331. The clamping plate 331 can be inserted between the two limiting strips 311 under the drive of the clamping cylinder 332.

[0040] During the feeding process, the metal strip is in contact with the upper side of the traction plate 31. When the metal strip needs to be fed, the clamping cylinder 332 is activated to move the clamping plate 331, thereby clamping the metal strip between the traction plate 31 and the clamping plate 331. Then, the traction electric cylinder 32 is activated to move the traction plate 31 and the clamping plate 331 as a whole away from the feed wheel 21, thereby realizing the feeding of the metal strip. During the clamping and contacting process of the clamping plate 331 and the traction plate 31, the uneven surface of the metal strip can be flattened.

[0041] Reference Figure 5 and Figure 6 A support frame 25 is fixedly provided on the upper side of the feed plate 2. The cutting assembly 4 includes a cutting cylinder 41 fixedly provided on the support frame 25 and a fixing plate 42 fixedly provided on the end of the moving rod on the cutting cylinder 41. A cutting blade 421 is fixedly provided on the side of the fixing plate 42 facing the feed plate 2. A cutting plate 26 flush with the upper surface of the traction plate 31 is fixedly provided on the side of the support frame 25. Limiting protrusions 262 are fixedly provided on the two opposite sides of the upper side of the cutting plate 26. At the same time, a cutting groove 261 located directly below the cutting blade 421 is opened on the cutting plate 26.

[0042] When the metal strip is fed to the area directly below the cutting blade 421, the cutting cylinder 41 is activated to move the fixing plate 42 and the cutting blade 421 toward the cutting groove 261, thereby cutting the metal strip and facilitating subsequent processing.

[0043] Reference Figure 6 The fixed plate 42 is provided with two elastic abutment members 43, wherein the elastic abutment member 43 includes a telescopic rod 431 fixed on the side of the fixed plate 42 facing the cutting plate 26 and a compression spring 432 located inside the telescopic rod 431. An abutment block 433 is integrally formed on the end of the telescopic rod 431 facing the cutting plate 26.

[0044] When the cutting blade 421 cuts the metal strip, the compression spring 432 is in a compressed state, which presses the bottom side of the abutment block 433 against the metal strip on the cutting plate 26, thus pre-pressing and reducing the possibility of the metal strip shifting or misaligning during cutting. When the cutting blade 421 is reset, the telescopic rod 431 moves synchronously away from the cutting plate 26. In the reset state, there is a gap between the bottom side of the abutment block 433 and the upper side of the cutting plate 26.

[0045] The implementation principle of this application embodiment is as follows:

[0046] During the metal strip feeding and cutting process, the metal strip is pre-wound around the outer circumference of the feeding wheel 21, then wound around the tension roller 23 and attached to the upper surface of the receiving plate 24 along the through gap, and fed along the upper surfaces of the receiving plate 24 and the traction plate 31.

[0047] When feeding and cutting are required, the clamping cylinder 332 is activated to move the clamping plate 331, thereby clamping the metal strip between the traction plate 31 and the clamping plate 331. Then, the traction cylinder 32 is activated to move the traction plate 31 and the clamping plate 331 as a whole away from the feeding wheel 21, thereby feeding the metal strip. When the metal strip is fed to the area directly below the cutting blade 421, the cutting cylinder 41 is activated to move the fixing plate 42 and the cutting blade 421 towards the cutting groove 261, thereby cutting the metal strip and facilitating subsequent processing.
