Description

Technical Field

[0001] The utility model relates to the technical field of metal stamping, in particular to a waste material recovery mechanism of a stamping device. Background Art

[0002] Tinplate cans are widely used for packaging food, medicine and other products. However, when making tinplate cans, a lot of tinplate waste is generated, and the waste is recycled by briquetting through a stamping device.

[0003] The common waste recycling mechanism of stamping equipment pours the waste into a container with an opening on the top, then uses a hydraulic cylinder to cover the opening on the top of the container, and then uses the hydraulic cylinder in the container to push the push plate to punch the waste into blocks. The common waste recycling mechanism of stamping equipment cannot add materials during the stamping process. Only when the stamping is completed and the waste blocks are taken out can waste be added again, so the efficiency is low.

[0004] A metal stamping waste recycling device disclosed in Chinese patent CN218660591U does not need to stop the injection of waste, and the sealing plate can be automatically opened and closed, which saves manpower and improves the discharge efficiency of waste. However, while solving the problem, the metal stamping waste recycling device has the following defects:

[0005] 1. The waste generated by tinplate can processing is usually in strips, soft and tough. Therefore, even if the baffle plate is in a vertical state, when a large amount of waste is poured into the feed hopper, the baffle plate will play a certain blocking role, causing the tinplate waste to be blocked in the feed hopper, affecting the subsequent unloading.

[0006] 2. When stamping waste, the baffle plate is horizontal, blocking the waste from falling and causing it to accumulate on top of the baffle plate. Therefore, when more tinplate waste is accumulated on top of the baffle plate, when you want to rotate the baffle plate again to make it vertical, part of the baffle plate rotates upward, so you need to push the waste upward. Tinplate waste is usually in strips and has poor fluidity, which requires a lot of force to open the baffle plate. Therefore, a high-power motor is required, and the baffle plate is easy to bend and damage, resulting in an unreasonable structural design, high cost, and easy damage. Utility Model Content

[0007] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0008] To this end, one purpose of the utility model is to propose a waste recovery mechanism for a stamping device, aiming to solve the problem of material blockage in the metal stamping waste recovery device in the prior art, and the unreasonable structural design, resulting in high cost and easy damage.

[0009] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one aspect provides a waste recovery mechanism of a stamping device, including a stamping box, characterized in that a feed trough is fixedly connected to the top of the stamping box, a first hydraulic cylinder is fixedly installed on one side of the stamping box, a push plate is fixedly connected to the output end of the first hydraulic cylinder, a sealing plate is fixedly connected to one side of the top of the push plate, a slide groove is provided at a position corresponding to the sealing plate on one side of the stamping box, a hole groove is provided at the top of the side of the stamping box away from the first hydraulic cylinder, a bracket is fixedly connected to the top of the hole groove, a second hydraulic cylinder is fixedly installed on the top of the bracket, a pressure plate equal to the size of the hole groove is fixedly connected to the output end of the second hydraulic cylinder, a feed trough is provided at the bottom of the stamping box at a position corresponding to the hole groove, a baffle is hinged on the bottom of one side of the feed trough, a third hydraulic cylinder is hinged on the bottom of the stamping box, and the output end of the third hydraulic cylinder is hinged to the baffle.

[0010] Preferably, any of the above schemes is that a vibration motor is fixedly mounted on the outer wall of the feed trough, which can speed up the material discharge rate and further avoid the problem of material blockage.

[0011] Preferably, any of the above schemes is that electric push rods and hooks are hinged on both sides of the stamping box, and the output end of the electric push rod is hinged to the hook, positioning blocks are fixedly connected to both sides of the bottom of the baffle, and a positioning rod is fixedly connected to one side of the positioning block, which can improve the firmness and protect the third hydraulic cylinder at the same time.

[0012] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0013] 1. After the sealing plate moves to one side of the feed trough, the bottom of the feed trough is completely opened without any obstruction, so the waste in the feed trough can smoothly fall into the inside of the stamping box without affecting the subsequent unloading.

[0014] 2. When the sealing plate is opened, there is sliding friction with the waste in the feed trough, so the movement of the sealing plate does not require very large force, so the structural design is reasonable, with the advantages of low cost and not easy to damage.

[0015] 3. By arranging a vibration motor on the outer wall of the feed chute, the feeding rate can be accelerated and waste materials will not block the feed chute, further improving practicality.

[0016] 4. By setting the hook and the positioning rod, the baffle can be positioned after the hook is sleeved on the surface of the positioning rod. At this time, when the pressure plate is lowered and the waste is punched, the third hydraulic cylinder is not subjected to force. Therefore, a small-power third hydraulic cylinder can be selected, thereby further reducing the cost.

[0026] The utility model provides a waste material recovery mechanism for a stamping device.

[0027] Embodiment 1:

[0028] like Figure 1-4 As shown, it includes a punching box 1, characterized in that a feed trough 11 is fixedly connected to the top of the punching box 1, and tinplate waste is added into the punching box 1 through the feed trough 11. A first hydraulic cylinder 2 is fixedly installed on one side of the punching box 1, and a push plate 21 is fixedly connected to the output end of the first hydraulic cylinder 2. A sealing plate 22 is fixedly connected to one side of the top of the push plate 21. During the punching process, the sealing plate 22 is used to block the bottom of the feed trough 11. A slide groove 12 is opened at a position corresponding to the sealing plate 22 on one side of the punching box 1. After the sealing plate 22 is slid to open the bottom of the feed trough 11, the sealing plate 22 can be moved to the outside of the punching box 1 through the slide groove 12, thereby ensuring that the bottom of the feed trough 11 is It can be opened smoothly. A hole groove 13 is provided on the top of the side of the stamping box 1 away from the first hydraulic cylinder 2. A bracket 3 is fixedly connected to the top of the hole groove 13. A second hydraulic cylinder 31 is fixedly installed on the top of the bracket 3. The output end of the second hydraulic cylinder 31 is fixedly connected to a pressure plate 32 with the same size as the hole groove 13, which is used for secondary stamping of tinplate waste. A feed chute 14 is provided at the bottom of the stamping box 1 at a position corresponding to the hole groove 13. A baffle 4 is hinged at the bottom of one side of the feed chute 14. A third hydraulic cylinder 5 is hinged at the bottom of the stamping box 1. The output end of the third hydraulic cylinder 5 is hinged to the baffle 4. The third hydraulic cylinder 5 can open and close the feed chute 14 by pushing and pulling the baffle 4.

[0029] Specifically, a first positioning sleeve 15 is fixedly connected to the bottom of one side of the discharge chute 14, and a positioning plate 41 is fixedly connected to one side of the bottom of the baffle 4. The baffle 4 is hinged in the first positioning sleeve 15 through the positioning plate 41. Through holes are provided on the first positioning sleeve 15 and the positioning plate 41, and the hinge is achieved by using a pin shaft to pass through the through hole.

[0030] Specifically, the bottom of the punch box 1 is fixedly connected with a second positioning sleeve 51 , the bottom of the baffle 4 is fixedly connected with a third positioning sleeve 52 , and both ends of the third hydraulic cylinder 5 are hinged in the second positioning sleeve 51 and the third positioning sleeve 52 , respectively.

[0031] Embodiment 2:

[0032] like Figure 1 As shown, on the basis of the first embodiment, a vibration motor 16 is fixedly installed on the outer wall of the feed trough 11. By starting the vibration motor 16, the feed trough 11 vibrates, so that the tinplate waste inside can be quickly lowered, and the problem of blockage can be avoided.

[0033] Embodiment three:

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, on the basis of Example 1 or Example 2, both sides of the stamping box 1 are hinged with an electric push rod 6 and a hook 61, and the output end of the electric push rod 6 is hinged with the hook 61, and the purpose of rotating the hook 61 can be achieved by extending and retracting the electric push rod 6, and the two sides of the bottom of the baffle 4 are fixedly connected with positioning blocks 42, and one side of the positioning block 42 is fixedly connected with a positioning rod 43, and the hook 61 is rotated to be sleeved on the outer surface of the positioning rod 43, so that the baffle 4 can be positioned, thereby avoiding the problem of the third hydraulic cylinder 5 being subjected to force when the second hydraulic cylinder 31 is stamping waste.

[0035] Specifically, Figure 4 As shown, a positioning shaft 1 63 and a positioning shaft 2 64 are fixedly connected on both sides of the stamping box 1, one end of the electric push rod 6 is hinged on the outer surface of the positioning shaft 1 63, and one end of the electric push rod 6 can rotate around the positioning shaft 1 63, and the hook 61 is hinged on the outer surface of the positioning shaft 2 64, and the hook 61 can rotate around the positioning shaft 2 64.

[0036] Specifically, Figure 4 As shown, one side of the hook 61 is fixedly connected to an extension plate 62, and one side of the extension plate 62 is fixedly connected to a fourth positioning sleeve 65. The output end of the electric push rod 6 is hinged to the fourth positioning sleeve 65. By retracting the electric push rod 6, the hook 61 can be pulled to rotate through the extension plate 62, so that the hook 61 is separated from the positioning rod 43. By extending the electric push rod 6, the hook 61 can be rotated to be sleeved on the surface of the positioning rod 43.

[0037] The working principle of the utility model is as follows: when in use, the first hydraulic cylinder 2 is retracted to make the sealing plate 22 open the bottom of the feed trough 11, and tinplate waste is added through the feed trough 11, and the waste falls into the punching box 1 through the feed trough 11. When a certain amount of waste enters the punching box 1, the first hydraulic cylinder 2 is extended, and the push plate 21 pushes and compresses the waste in the punching box 1 to the bottom of the pressure plate 32, and the sealing plate 22 gradually blocks the bottom of the feed trough 11. At this time, the waste that continues to be added will stay in the feed trough 11. When the push plate 21 is extended to the limit, the side of the push plate 21 that contacts the waste is aligned with the side of the pressure plate 32 close to the feed trough 11. At this time, the second hydraulic cylinder 31 is extended, and the pressure plate 32 descends, 21 The waste material that has been initially compressed is subjected to secondary compression. After the compression is completed, the first hydraulic cylinder 2, the second hydraulic cylinder 31, the electric push rod 6 and the third hydraulic cylinder 5 are contracted, the push plate 21 and the pressure plate 32 are reset, and the baffle plate 4 is rotated to open the feed chute 14, so that the compressed waste material falls through the feed chute 14. After the waste material is discharged, the third hydraulic cylinder 5 is extended to make the baffle plate 4 close the feed chute 14 again, and then the electric push rod 6 is extended to make the hook 61 sleeve on the surface of the positioning rod 43. After the push plate 21 is reset, the bottom of the feed chute 11 is opened, and the waste material in the feed chute 11 will fall into the interior of the stamping box 1 with gravity. The waste material in the feed chute 11 can also be vibrated by starting the vibration motor 16 to accelerate its falling speed.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. By contracting the first hydraulic cylinder 2 and moving the sealing plate 22 to one side of the feed trough 11, the bottom of the feed trough 11 is completely opened without any obstruction, so the waste in the feed trough 11 can smoothly fall into the inside of the punching box 1 without affecting the subsequent unloading.

[0040] 2. The bottom of the feed trough 11 is opened by sliding the sealing plate 22 to one side. Therefore, during the opening process of the sealing plate 22, there is sliding friction with the waste in the feed trough 11. Therefore, the movement of the sealing plate 22 does not require very large force and is not easy to bend and damage. Therefore, the structural design is reasonable and has the advantages of low cost and not easy to damage.

[0041] 3. By arranging a vibration motor 16 on the outer wall of the feed trough 11, the vibration motor 16 can vibrate the waste in the feed trough 11 during the unloading process, thereby speeding up the unloading rate and preventing the waste from clogging the feed trough 11, further improving practicality.

[0042] 4. By setting the hook 61 and the positioning rod 43, the baffle 4 can be positioned after the hook 61 is sleeved on the surface of the positioning rod 43. At this time, the second hydraulic cylinder 31 extends and the pressure plate 32 is lowered. When the waste is punched, the hook 61 and the positioning rod 43 are subjected to force to fix the baffle 4, and the third hydraulic cylinder 5 is not subjected to force. Therefore, the function of the third hydraulic cylinder 5 is to open and close the baffle 4, so that a small-power third hydraulic cylinder 5 can be selected, thereby further reducing the cost.
