Description

Technical Field

[0001] This patent relates to the field of waste recycling of sheet metal, specifically a waste recycling device for cutting electroplated tin sheets. Background Technology

[0002] Electroplated tin sheets can be pre-treated by physical methods such as mechanical crushing and screening to make them into particles or powders of a certain size. Then, tin and other valuable metals are separated from impurities using technologies such as magnetic separation and flotation. For example, magnetic separation can separate magnetic materials such as iron, while flotation can enrich metals such as tin based on the differences in surface properties of different materials.

[0003] However, existing tin-plated sheet waste is shredded by a crusher. During the shredding process, the waste material cut from the tin-plated sheet may be quite long, and its tail end may swing back and forth, potentially causing injury. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a waste recycling device for cutting electroplated tin plates.

[0005] The technical solution adopted by this patent to solve its technical problem is: a waste recycling device for cutting electroplated tinplate, including a crusher and a feeding hopper. The upper end of the crusher is equipped with a feeding hopper, which is connected to the inner cavity of the crusher. A cutting mechanism is slidably installed on the side wall of the feeding hopper, and the cutting mechanism can cut external electroplated tinplate waste.

[0006] The cutting mechanism includes a hydraulic push rod, a stamping cutter, a fixing block, and a guide groove. The hydraulic push rod is installed on the side wall of the feed hopper, and the stamping cutter is installed at the output end of the hydraulic push rod. A through groove is opened in the side wall of the feed hopper, through which the stamping cutter can penetrate the side wall of the feed hopper. A fixing block is installed on the inner side wall of the feed hopper, and a guide groove is opened in the upper wall of the fixing block. The guide groove penetrates the lower wall of the fixing block, and external electroplated tin waste can be inserted into the guide groove. The stamping cutter is located below the fixing block and can fit against the lower wall of the fixing block.

[0007] Furthermore, the crusher includes a casing, a rotating shaft, and a crushing wheel. The rotating shaft is rotatably installed in the inner cavity of the casing. There are two rotating shafts in total, and the two rotating shafts are arranged symmetrically in the inner cavity of the casing. The crushing wheel is installed on the outer side of the rotating shaft. Both rotating shafts pass through the side wall of the casing and are connected to an external motor. The two rotating shafts rotate in opposite directions.

[0008] Furthermore, a feeding trough is provided in the middle of the upper wall of the casing, the feeding trough is connected to the inner cavity of the feeding hopper, and the feeding trough is arranged between the two crushing wheels.

[0009] Furthermore, support legs are installed at the four corners of the outer wall of the housing.

[0010] Furthermore, a support frame is installed on the lower wall of the fixing block. The support frame has a U-shaped cross-section and can support the stamping cutter. A placement groove is opened on the upper wall of the support frame. One end of a spring is installed in the placement groove, and a whetstone is installed on the other end of the spring. The whetstone can sharpen the stamping cutter.

[0011] Furthermore, the side wall of the support frame is provided with a spherical groove, and a ball bearing is installed in the spherical groove. The ball bearing can fit against the side wall of the stamping cutter.

[0012] The beneficial effects of this patent are:

[0013] This device incorporates a cutting mechanism within its feed hopper, enabling it to preliminarily cut the tin-plated waste material using a stamping cutter. This shortens the overall length of the material, preventing the tail end of the tin-plated waste material from wobbling back and forth during crushing and thus avoiding potential injury.

[0014] In addition, the device is equipped with a whetstone on the support frame so that it can be polished when the stamping cutter moves, ensuring that the cutting mechanism can smoothly cut the electroplated tin plate. Attached Figure Description

[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This is a schematic diagram of the structure of this patent. A waste recycling device for cutting electroplated tinplate includes a crusher 1 and a feeding hopper 2. The feeding hopper 2 is installed at the upper end of the crusher 1 and is connected to the inner cavity of the crusher 1. A cutting mechanism 3 is slidably installed on the side wall of the feeding hopper 2. The cutting mechanism 3 can cut external electroplated tinplate waste.

[0022] By setting the cutting mechanism 3, the waste of tin-plated board can be cut, thereby shortening the overall length of the waste tin-plated board and preventing the tail end of the waste tin-plated board from swinging back and forth during crushing, thus avoiding injury.

[0023] The cutting mechanism 3 includes a hydraulic push rod 31, a stamping cutter 32, a fixing block 33, and a guide groove 34. The hydraulic push rod 31 is installed on the side wall of the feed hopper 2. The output end of the hydraulic push rod 31 is equipped with a stamping cutter 32. A through groove 4 is provided on the side wall of the feed hopper 2. The stamping cutter 32 can penetrate the side wall of the feed hopper 2 through the through groove 4. A fixing block 33 is installed on the inner side wall of the feed hopper 2. A guide groove 34 is provided on the upper wall of the fixing block 33. The guide groove 34 penetrates the lower wall of the fixing block 33. External electroplated tin plate waste can be inserted into the guide groove 34. The stamping cutter 32 is located below the fixing block 33. The stamping cutter 32 can fit against the lower wall of the fixing block 33.

[0024] When the tin-plated waste enters the feed hopper 2, it is inserted into the guide groove 34 on the fixed block 33. Then, the hydraulic push rod 31 pushes the punch cutter 32 to move, thereby cutting the tin-plated waste.

[0025] The crusher 1 includes a housing 10, a rotating shaft 11, and a crushing wheel 12. The rotating shaft 11 is rotatably installed in the inner cavity of the housing 10. There are two rotating shafts 11, which are arranged symmetrically in the inner cavity of the housing 10. The crushing wheel 12 is installed on the outer side of the rotating shaft 11. Both rotating shafts 11 pass through the side wall of the housing 10 and are connected to an external motor. The two rotating shafts 11 rotate in opposite directions.

[0026] An external motor drives two rotating shafts 11 to rotate, causing the crushing wheel 12 to crush the tin-plated waste. This facilitates the storage of the tin-plated waste and also makes it easier to process it into powder later.

[0027] A feed chute 5 is provided in the middle of the upper wall of the casing 10. The feed chute 5 is connected to the inner cavity of the feed hopper 2 and is located between the two crushing wheels 12.

[0028] Support legs 6 are installed at the four corners of the outer side wall of the casing 10.

[0029] A support frame 7 is installed on the lower wall of the fixing block 33. The support frame 7 has a U-shaped cross section and can support the punching cutter 32. A placement groove 8 is opened on the upper wall of the support frame 7. One end of the spring 9 is installed in the placement groove 8, and a whetstone 13 is installed on the other end of the spring 9. The whetstone 13 can grind the punching cutter 32.

[0030] Since the stamping cutter 32 cuts the electroplated tinplate waste by extrusion and shearing, its edges tend to become dull after a period of use. Therefore, this device is equipped with a whetstone 13 on its support frame 7 so that the whetstone 13 can polish the stamping cutter 32 when it is moving, thereby improving the efficiency of this device in cutting electroplated tinplate waste.

[0031] The side wall of the support frame 7 is provided with a spherical groove 14, and a ball bearing 15 is installed in the spherical groove 14. The ball bearing 15 can fit against the side wall of the stamping cutter 32.

[0032] By setting the ball bearings 15, the friction between the stamping cutter 32 and the support frame 7 can be reduced when the stamping cutter 32 moves, making the movement of the stamping cutter 32 smoother.

[0033] In operation, the worker puts the tin-plated waste into the knife feed hopper 2 and inserts it into the guide groove 34 on the fixed block 33. Then, the hydraulic push rod 31 pushes the punch cutter 32 to move, thereby cutting the tin-plated waste. The cut tin-plated waste will enter the crusher 1 through the feed chute 5, and then be crushed by the internal crushing wheel 12.

[0034] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
