Description

Technical Field

[0001] This utility model relates to the field of cutting technology for beverage can production, specifically a cutting device for beverage can production. Background Technology

[0002] Aluminum cans are usually made of aluminum. During the production process, a cutting device is needed to cut large, long strips of aluminum into appropriately sized, shorter sheets for easier processing and handling.

[0003] In the prior art, an aluminum plate cutting device for beverage can production, with publication number "CN217571154U", involves cutting an aluminum plate on a fixed platform. The plate is then conveyed to the right by the cooperation of rollers and shafts. The cutting blade cuts the aluminum plate under the push of a hydraulic cylinder. Simultaneously, a pressure block contacts the aluminum plate first and elastically presses it, effectively preventing the aluminum plate from warping during cutting and improving stability and cutting quality.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Although this cutting device can cut aluminum sheets for beverage can production, the lack of a limiting structure for the aluminum sheet makes it very easy for the sheet to shift back and forth during the rightward conveyance by the rollers. Once the aluminum sheet shifts back and forth, the subsequent cutting blade will cut at an angle, resulting in an unreasonable cut. Secondly, the baffle in this cutting device is a fixed structure, so its position cannot be adjusted during use. This means that the cutting device can only cut aluminum sheets of the same length and cannot adjust the cutting length according to production needs, thus limiting its applicability.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] Example 1:

[0029] A cutting device for producing aluminum cans includes a cutting table 1, an electric hydraulic push rod 4, a cutting frame 5, a connecting knife holder 6, a cutting knife 7, and a cutting channel 10. An aluminum plate 2 for aluminum cans is placed on the upper surface of the cutting table 1. The cutting frame 5 is fixedly connected to the left side of the upper surface of the cutting table 1, supporting the electric hydraulic push rod 4. The electric hydraulic push rod 4 is installed in the middle of the upper surface of the cutting frame 5. The electric hydraulic push rod 4 is electrically connected to an external control cabinet via a wire. The connecting knife holder 6 is installed at the lower end of the electric hydraulic push rod 4. Equipped with a cutting blade 7, the cutting blade 7 has a front-to-back width greater than the front-to-back width of the aluminum plate 2 for the aluminum can. When working, the electric hydraulic push rod 4 can drive the cutting blade 7 to move downwards through the connecting blade holder 6 to cut the aluminum plate 2 for the aluminum can. The cutting blade 7 is a separately detachable structure, which makes it convenient for staff to replace it later. A cutting groove 10 is provided on the left side of the upper end face of the cutting table 1. The cutting groove 10 matches the cutting blade 7 and prevents the cutting blade 7 from colliding with the cutting table 1 during the downward cutting process, thus avoiding damage.

[0030] A limiting component 3 is provided on the right side of the upper end face of the cutting table 1. The limiting component 3 is used to limit and guide the aluminum plate 2 of the can during the cutting process to prevent the aluminum plate 2 of the can from shifting back and forth during the conveying and cutting process. A material blocking component 9 is provided on the left side of the upper end face of the cutting table 1. The material blocking component 9 is used to block the aluminum plate 2 of the can so that the cutting blade 7 can cut the aluminum plate 2 of the can to the same length. A conveying component 8 is provided below the cutting frame 5. The conveying component 8 can not only convey the aluminum plate 2 of the can to the left, but also has the ability to press and limit the aluminum plate 2 of the can to prevent the aluminum plate 2 of the can from tilting upwards during the cutting process of the cutting blade 7.

[0031] The conveying assembly 8 includes a support frame 81, an extension support plate 82, a first electric push rod 83, a connecting plate 84, a limiting slot 85, a second low-speed motor 86, and an active conveying roller 87. The cutting frame 5 has a limiting slot 85 on its side, which matches the connecting plate 84. The limiting slot 85 can limit the connecting plate 84 to prevent it from shaking or shifting during lifting and lowering. The support frame 81 is installed below the cutting frame 5 and is connected to the connecting plate 84 by welding. The support frame 81 can support and limit the active conveying roller 87 and the driven conveying roller 88 respectively. The lower end of the support frame 81 is higher than the lower side of the annular side of the active conveying roller 87 and the driven conveying roller 88 to prevent the support frame 81 from contacting the aluminum plate 2 for the can first.

[0032] The support frame 81 is provided with connecting plates 84 at both ends. The connecting plates 84 can support the support frame 81. The lower end face of the connecting plate 84 is equipped with a first electric push rod 83. The first electric push rod 83 is electrically connected to the external control cabinet next to it through the wire. When working, the first electric push rod 83 can drive the support frame 81 to rise and fall through the connecting plate 84, thereby adjusting the working height of the active conveyor roller 87 and the driven conveyor roller 88. The cutting table 1 is symmetrically fixedly connected to the front and rear ends with extension support plates 82. The extension support plates 82 are connected to the cutting table 1 by welding. The extension support plates 82 can support the first electric push rod 83. The left side of the front end face of the support frame 81 is equipped with a second low-speed motor 86. The second low-speed motor 86 is electrically connected to the external control cabinet next to it through the wire. When working, the second low-speed motor 86 can drive the active conveyor roller 87 to rotate at low speed.

[0033] A drive conveyor roller 87 is installed at the rear end of the second low-speed motor 86, and a driven conveyor roller 88 is installed on the right side inside the support frame 81. The drive conveyor roller 87 and the driven conveyor roller 88 have the same specifications and operating height. The drive conveyor roller 87 and the driven conveyor roller 88 can not only convey the aluminum plate 2 for the can to the left, but also press and limit the area of ​​the aluminum plate 2 to be cut, so as to prevent the aluminum plate 2 for the can from curling up during the cutting process of the cutting blade 7. The drive conveyor roller 87 is located behind... The driven conveyor roller 88 is provided with a drive pulley 812 at one end and a driven pulley 89 at the rear end. Both the drive pulley 812 and the driven pulley 89 are synchronous belt pulleys 811. A synchronous belt 811 connects the driven pulley 89 and the drive pulley 812. The drive pulley 812, which is a synchronous belt pulley 811, can drive the driven pulley 89, which is a synchronous belt pulley 811, to rotate synchronously and in the same direction through the synchronous belt 811, so that the driven pulley 89 drives the driven conveyor roller 88 and the drive conveyor roller 87 to rotate synchronously and in the same direction.

[0034] A lower guide roller 813 is installed directly below both the active conveyor roller 87 and the driven conveyor roller 88. The upper side of the annular side of the lower guide roller 813 is one millimeter higher than the upper surface of the cutting table 1. The lower guide roller 813 is a rotatable structure. The fact that the upper side of the annular side of the lower guide roller 813 is one millimeter higher than the upper surface of the cutting table 1 can reduce the frictional resistance between the aluminum plate of the can and the cutting table 1, so that the active conveyor roller 87 and the driven conveyor roller 88 can convey the aluminum plate of the can to the left more smoothly. The annular side of both the active conveyor roller 87 and the driven conveyor roller 88 is provided with anti-slip silicone sleeves. The anti-slip silicone sleeves make the annular side of the active conveyor roller 87 and the driven conveyor roller 88 more slip-resistant, and prevent the active conveyor roller 87 and the driven conveyor roller 88 from easily slipping during the conveying of the aluminum plate of the can at the lower end.

[0035] Example 2:

[0036] Based on Embodiment 1, in this embodiment, by loosening the positioning screw 97, the second support frame 91 can be moved left and right. The second support frame 91 will drive the blocking plate 93 to move left and right together via the second electric push rod 92, so that the operator can match and adjust the left and right positions of the blocking plate 93 according to different cutting length requirements, thereby improving the applicability of this device.

[0037] The material blocking assembly 9 includes a second support frame 91, a second electric push rod 92, a blocking plate 93, a support rod 95, and a support side plate 96. The support side plate 96 is fixedly connected to the left side of the upper end face of the cutting table 1. The support rod 95 is fixedly connected to the inner wall of the support side plate 96. The support side plate 96 can support the support rod 95 so that the support rod 95 can support and limit the second support frame 91. The second support frame 91 is movably arranged on the annular side of the support rod 95. The second support frame 91 can support the second electric push rod 92. The second electric push rod 92 is installed on the upper side of the inner wall of the second support frame 91. The second electric push rod 92 is electrically connected to the adjacent external control cabinet through a wire. When working, the second electric push rod 92 can drive the blocking plate 93 to rise and fall. The blocking plate 93 is installed at the lower end of the second electric push rod 92. The blocking plate 93 can block the aluminum plate 2 of the can that moves to the left so that the cutting blade 7 can cut the aluminum plate 2 of the can to the same length.

[0038] A follower rod 94 is provided on the front side of the upper end of the baffle plate 93. The follower rod 94 is connected to the baffle plate 93 by welding. The follower rod 94 can limit the position of the baffle plate 93 to prevent the baffle plate 93 from shaking or shifting during lifting and lowering. A positioning screw 97 is threaded on the lower side of the front end of the second support frame 91. When the positioning screw 97 is tightened, it can fix the second support frame 91 to prevent displacement during use. When it is loosened, it will release the positioning of the second support frame 91, so that the operator can move the second support frame 91 left and right. The support rod 95 has a digital scale line on its annular side, which makes it convenient for the operator to make precise adjustments to the left and right position of the second support frame 91.

[0039] Example 3:

[0040] Based on Embodiment 1, in this embodiment, by controlling the first low-speed motor 32 to rotate forward, the first low-speed motor 32 can drive the limiting side plates 33 on both the front and rear sides to move inward synchronously through the bidirectional threaded rod 35 and the connecting seat 34. Conversely, it can drive the limiting side plates 33 on both the front and rear sides to move outward synchronously. This allows the workers to match and adjust the spacing between the limiting side plates 33 on both the front and rear sides according to the different front and rear widths of the aluminum plates 2 for aluminum cans. The limiting side plates 33 with the adjusted spacing can limit and guide the aluminum plates 2 for aluminum cans, preventing the aluminum plates 2 for aluminum cans from shifting forward and backward during the conveying and cutting process, thereby ensuring the cutting qualification rate of the subsequent cutting blade 7.

[0041] The limiting component 3 includes a first support frame 31, a first low-speed motor 32, a limiting side plate 33, a connecting seat 34, a bidirectional threaded rod 35, and a limiting through cavity 36. The first support frame 31 is fixedly connected to the right side of the upper end face of the cutting table 1. The first support frame 31 can support the bidirectional threaded rod 35 and the first low-speed motor 32. The first low-speed motor 32 is installed on the upper side of the front end face of the first support frame 31. The first low-speed motor 32 is electrically connected to the external control cabinet next to it through a wire. When working, the first low-speed motor 32 can drive the bidirectional threaded rod 35 to rotate forward or reverse at low speed.

[0042] A bidirectional threaded rod 35 is mounted at the rear end of the first low-speed motor 32. The front and rear external threads on the annular side of the bidirectional threaded rod 35 rotate in opposite directions to the rear external thread on the annular side. Connecting seats 34 are symmetrically mounted on the front and rear threads of the annular side of the bidirectional threaded rod 35. The connecting seats 34 have internal threaded through holes that mesh with the bidirectional threaded rod 35. When the bidirectional threaded rod 35 rotates, the internal threaded through holes can drive the connecting seats 34 on both sides to move synchronously and in opposite directions. A limiting side plate 33 is provided at the lower end of the 34. The limiting side plate 33 is connected to the connecting seat 34 by welding. The bottom of the limiting side plate 33 is in contact with the upper surface of the cutting table 1. The limiting side plate 33 can limit the aluminum plate 2 for the can on the cutting table 1 to prevent the aluminum plate 2 for the can from shifting forward or backward during the cutting process. A limiting cavity 36 is opened on the upper surface of the first support frame 31. The limiting cavity 36 matches the connecting seat 34. The limiting cavity 36 can limit the connecting seat 34 to prevent the connecting seat 34 from shaking or shifting during the movement and use.

[0043] Working Principle: In the production process of aluminum cans, this device is used to cut large, long strips of aluminum cans into appropriately sized shorter aluminum plates using aluminum plate 2. The operator first controls the first low-speed motor 32 to rotate forward via an external control cabinet. This causes the first low-speed motor 32 to drive the bidirectional threaded rod 35 to rotate forward at a low speed. The forward-rotating bidirectional threaded rod 35, through the connecting seat 34, drives the front and rear limiting side plates 33 to move inward synchronously. Similarly, when the first low-speed motor 32 is controlled to rotate in reverse, the front and rear limiting side plates 33 move outward synchronously, allowing the operator to... The system can adjust the spacing between the front and rear limiting side plates 33 according to the different widths of aluminum plates 2 used for aluminum cans. Then, by loosening the positioning screws 97 with an external wrench, the operator can move the second support frame 91 left and right. The second support frame 91 will move the blocking plate 93 left and right together via the second electric push rod 92. During this process, when the blocking plate 93 moves to the left, the length of the aluminum plate 2 used for aluminum cans that is cut will increase accordingly, and vice versa. This allows the operator to adjust the cutting length according to different widths of aluminum plates 2 used for aluminum cans. The left and right positions of the blocking plate 93 are adjusted to match the required cutting length, and the support rod 95 supports and limits the second support frame 91 to prevent it from shaking or shifting during use. After the blocking plate 93 is adjusted to the required position, the positioning screw 97 is tightened to prevent the second support frame 91 from shifting again. At this time, the second electric push rod 92 can be controlled to move the blocking plate 93 downward to contact the upper surface of the cutting table 1. Then, the worker can use the aluminum plate 2 to cut the long, uncut aluminum can from right to left. The aluminum plate 2 is moved to the left and placed flat on the upper surface of the cutting table 1. During this process, the aluminum plate 2 for the can needs to be positioned between the limiting side plates 33 and pass under the active conveyor roller 87 and the driven conveyor roller 88. Then, the left end of the aluminum plate 2 for the can should be brought into contact with the right end of the blocking plate 93. At this time, the first electric push rod 83 is controlled to drive the support frame 81 to descend through the connecting plate 84. The support frame 81 will drive the active conveyor roller 87 and the driven conveyor roller 88 to descend together, so that the active conveyor roller 87 and the driven conveyor roller 88 contact the aluminum plate 2 for the can below and limit its movement (see reference). Figure 1 To prevent the aluminum sheet 2 from warping upwards during the subsequent cutting process by the cutting blade 7, the operator can control the electric hydraulic push rod 4 to move the cutting blade 7 downwards via the connecting blade holder 6 to cut the aluminum sheet 2. After cutting, the cutting blade 7 is first moved upwards to its initial position, then the second electric push rod 92 is controlled to move the blocking plate 93 upwards. Subsequently, the second low-speed motor 86 is started, causing the second low-speed motor 86 to drive the active conveyor roller 87 to rotate and transport the cut aluminum sheet 2 to the left, so that the operator standing on the left side of the cutting table 1 can place the cut aluminum sheet 2 into the collection box next to it. Figure 1(As shown in the drawing), during this process, the active conveyor roller 87 drives the driven pulley 89 to rotate synchronously and in the same direction via the active pulley 812 and the synchronous belt 811. The driven pulley 89 then drives the driven conveyor roller 88 to rotate synchronously and in the same direction as the active conveyor roller 87, continuing to convey the aluminum sheet 2 for the cans to the left. Once the cut aluminum sheet 2 is separated from the active conveyor roller 87, the worker can remove it to prevent the cut aluminum sheet 2 from obstructing the blocking plate 93 from blocking the subsequent conveyed aluminum sheet 2. After the aluminum plate 2 for the can is removed, the staff standing next to the external control cabinet can control the second electric push rod 92 to move the blocking plate 93 down again so that the blocking plate 93 can block the aluminum plate 2 for the can again. When the left end of the aluminum plate 2 for the can that is subsequently conveyed is in contact with the blocking plate 93 again, the second low-speed motor 86 can be turned off to stop the active conveying roller 87 from rotating. Then, the electric hydraulic push rod 4 can be controlled again to drive the cutting blade 7 down through the connecting blade holder 6 to cut the aluminum plate 2 for the can again to the same length.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
