Description

A curling wheel device Technical Field

[0001] This utility model relates to the field of metal packaging container manufacturing technology, and in particular to a crimping wheel device. Background Technology

[0002] Against the backdrop of the booming development of the modern packaging industry, tin cans, with their excellent sealing properties, corrosion resistance, and recyclability, have become an important packaging medium for the food, beverage, and chemical industries. However, during the tin can production process, the quality of the edge rolling directly affects its sealing performance and service life. Traditional edge rolling processes suffer from problems such as low efficiency and insufficient precision. To address these issues, edge rolling wheel devices have emerged. These devices effectively improve the quality and production efficiency of tin can edge rolling, becoming a key piece of equipment driving the upgrading of the tin can packaging industry.

[0003] A search revealed a Chinese publication (CN209477021U) disclosing a detachable tin can edge-rolling device, comprising a workbench and a support plate. A support rod is fixedly installed at the bottom corner of the support plate, and the other end of the support rod is fixedly installed on the top of the workbench. A hydraulic rod fixing frame is bolted to the top of the support plate, and a hydraulic rod is bolted to the hydraulic rod fixing frame. A control button for hydraulic rod one and a control button for hydraulic rod two are provided on the front side of the workbench. A working groove is formed on one side of the workbench, and a hydraulic rod two is bolted to the inner wall of the working groove away from the opening end. A fixing device is connected to the inner wall of the bottom of the working groove via a pulley and a slide rail. The piston rod of hydraulic rod two is bolted to the fixing device. A connecting groove is formed on the top of the counter-edge seat. This detachable tin can edge-rolling device is reasonably designed.

[0004] The patent description mentions that "the fixing device 11 and the anti-edge seat 12 of this detachable iron can edge rolling device can be disassembled and replaced, so as to be applicable to the use of different models of metal cans." However, in the actual processing, when processing iron cans of different sizes, the anti-edge seat needs to be disassembled to adapt to the size of the iron can. However, disassembling the anti-edge seat of the device will waste time and reduce the processing efficiency of the device. In view of the above problems, an edge rolling wheel device is proposed. Summary of the Invention

[0005] The present invention proposes a crimping wheel device, which aims to improve the problem that some devices in the prior art need to be disassembled and replaced in order to adapt to the processing of iron cans of different sizes.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A crease-rolling wheel device includes a sliding seat and a base wheel. A sleeve is slidably connected to the outside of the sliding seat, and a clamping mechanism is slidably connected to the outside of the sleeve. A base is slidably connected to the bottom of the sliding seat, and a pressure-applying mechanism is slidably connected to the sliding seat. A wear-resistant and corrosion-resistant coating is applied to the outer working surface of the base wheel by plasma spraying. The wear-resistant and corrosion-resistant coating directly contacts the mouth of the iron can to complete the crease-rolling operation, thereby enhancing the wear resistance and corrosion resistance of the base wheel.

[0008] The clamping mechanism includes a ring, the inner wall of which is slidably connected to the outside of the sleeve. A rotating rod is fixedly connected inside the ring, and a connecting rod is rotatably connected to the outside of the rotating rod. The connecting rod is rotatably connected to the inside of the sleeve, and an arc-shaped clamping plate is fixedly connected to the outside of the connecting rod. An elastic component is fixedly connected to the outside of the clamping mechanism.

[0009] The above solution, with its sliding connection between the sliding seat, sleeve, and base, provides the device with flexible movement and precise guidance. The clamping mechanism, with its linked design of the ring, rotating rod, connecting rod, and arc-shaped clamping plate, combined with the elastic components, can quickly and securely clamp the tin can, ensuring it remains fixed during the edge-rolling process and preventing shaking that could affect the edge-rolling quality. The pressure mechanism provides continuous pressure to the sliding seat, pushing the tin can into close contact with the edge-rolling components, ensuring smooth edge-rolling operations and effectively improving edge-rolling efficiency and finished product quality. The overall structure is compact, easy to operate, and possesses good practicality and reliability.

[0010] As a further description of the above technical solution:

[0011] The pressure-applying mechanism includes a guide rod, the outer side of which is slidably connected to the inside of the sliding seat. A fixing block is fixedly connected to one outer end of the guide rod, and a fixing plate is fixedly connected to the other outer end of the fixing block. A pressure spring is sleeved on the outer side of the guide rod, one outer end of which is fixedly connected to the outer side of the fixing plate, and the other outer end of which is fixedly connected to the outer side of the sliding seat. The bottom of the fixing block is fixedly connected to the top of the base, the bottom of the fixing plate is fixedly connected to the top of the base, and a drive assembly is fixedly connected to the top of the base.

[0012] The above solution achieves the following: the guide rod precisely guides the movement of the sliding seat to prevent deviation; the fixed block and fixed long plate provide stable support to enhance structural stability; the pressure spring provides continuous adjustable pressure to ensure uniform force on the tin can; and the drive component flexibly controls the movement and reset of the sliding seat to ensure stable edge rolling operations.

[0013] As a further description of the above technical solution:

[0014] The elastic component includes a connecting plate, which is fixedly connected to the outside of the clamping mechanism. An arc-shaped rod is slidably connected inside the connecting plate. A fixing plate is fixedly connected to the outside of the sleeve. One outer end of the arc-shaped rod is fixedly connected to the inside of the fixing plate. A limiting spring is sleeved on the outside of the arc-shaped rod. One outer end of the limiting spring is fixedly connected to one side of the fixing plate, and the other outer end of the limiting spring is fixedly connected to one side of the connecting plate.

[0015] The above solution involves connecting the connecting plate to the clamping mechanism, using an arc-shaped rod to provide sliding guidance, and connecting the limiting spring to the fixed plate at one end and the connecting plate at the other. During clamping, the spring generates a restoring force through elastic deformation, which drives the arc-shaped clamping plate to stably clamp the iron can, ensuring balanced clamping force and improving clamping reliability and the stability of the edge-rolling operation.

[0016] As a further description of the above technical solution:

[0017] The drive assembly includes a fixed base, the bottom of which is fixedly connected to the top of the base, and an electric push rod is fixedly connected inside the fixed base. The drive end of the electric push rod is fixedly connected to the outer side of the sliding base.

[0018] The above solution provides a solid support for the electric push rod by ensuring the fixed seat is securely installed on the base. The electric push rod precisely controls the movement and reset of the sliding seat, enabling flexible adjustment of the thrust and stroke. This ensures the stable and efficient operation of the edge-rolling wheel device and effectively improves the automation and accuracy of the edge-rolling operation.

[0019] As a further description of the above technical solution:

[0020] An L-shaped fixed support is fixedly connected to the outside of the sliding seat, and a motor is fixedly connected inside the L-shaped fixed support. The drive end of the motor is fixedly connected inside the sliding seat, and the drive end of the motor is rotatably connected inside the sliding seat.

[0021] The above solution uses an L-shaped fixed support to securely connect the sliding seat and the motor, providing a reliable installation base for the motor. The motor drives the sliding seat to rotate through the drive end, precisely controlling the sleeve speed to ensure smooth rotation of the tin can, thus enabling stable edge rolling operations and effectively improving edge rolling quality and production efficiency.

[0022] As a further description of the above technical solution:

[0023] A support base is fixedly connected to the top of the base, and a motor is fixedly connected to the top side of the inside of the support base.

[0024] With the above solution: the support base stands firmly on the top of the base, providing stable support for the second motor. The second motor is installed in it and can output power stably to drive the base wheel to run efficiently, ensuring continuous and stable power for the edge rolling operation, avoiding the impact of shaking and displacement on the edge rolling accuracy, and improving the overall reliability and processing quality of the device.

[0025] As a further description of the above technical solution:

[0026] The drive end of the second motor is fixedly connected to a drive rod, and the outer side of the base wheel is fixedly connected to the outside of the drive rod.

[0027] The above solution involves motor 2 driving the base wheel to rotate via a drive rod. The base wheel can then be rolled over the edge of the tin can. The coating on the base wheel enhances its wear resistance and bonding strength, ensuring stable contact with the tin can during rolling, reducing wear, extending service life, and improving rolling quality and processing efficiency.

[0028] As a further description of the above technical solution:

[0029] The drive rod has a keyway that is slidably connected inside, and the keyway is slidably connected outside to the inside of the base wheel.

[0030] With the above solution, the keyway inside the drive rod slides into the base wheel, enabling stable power transmission and flexible loading, unloading, and position adjustment of the base wheel. This connection method effectively prevents the base wheel from slipping, ensures power transmission efficiency, and facilitates equipment maintenance and component replacement.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the connecting plate is pulled to drive the ring to slide, and the ring moves the connecting rod through the rotating rod, thereby driving the arc-shaped clamping plate to open. After the iron can is placed, the connecting plate is released, the limit spring returns to its original position, and the arc-shaped clamping plate is pushed to clamp and fix the iron can, realizing fast and stable clamping of the iron can. This ensures that iron cans of different sizes remain fixed during the edge rolling process, and improves the stability and adaptability of the edge rolling wheel device.

[0033] 2. In this utility model, the electric push rod initiates the contraction and extension, causing the sliding seat to slide along the guide rod. At the same time, the pressure spring is compressed, thereby providing pressure to the sliding seat and pushing the tin can to be rolled. Through the synergistic action of the electric push rod and the spring, the movement of the sliding seat and the pressure can be controlled. During the rolling process, the continuous and stable pressure can ensure that the tin can is in close contact with the base wheel, improving the rolling quality and efficiency.

[0040] 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.

[0041] Referring to Figures 1, 2, and 4, one embodiment of this utility model provides a hemming wheel device, including a sliding seat 1 and a base wheel 11. The sliding seat 1 serves as a load-bearing and guiding element. A sleeve 2 is slidably connected to the outside of the sliding seat 1, and the inside of the sleeve 2 is used to hold an iron can. A clamping mechanism 3 is slidably connected to the outside of the sleeve 2, and the clamping mechanism 3 is used to fix the iron can inside the sleeve 2. A base 5 is slidably connected to the bottom of the sliding seat 1, and the base 5 is the basic support component of the entire device. A pressure applying mechanism 4 is slidably connected to the sliding seat 1, and the pressure applying mechanism 4 is used to provide pressure to the sliding seat 1. The iron can is constantly subjected to thrust, thus achieving edge curling. The outer working surface of the base wheel 11 is coated with a wear-resistant and corrosion-resistant coating using a plasma spraying process. This coating directly contacts the iron can opening to complete the edge curling operation, enhancing the wear and corrosion resistance of the base wheel 11. The wear-resistant and corrosion-resistant coating here consists of tungsten carbide particles. The most prominent functional characteristics of the tungsten carbide coating are its extremely high hardness and excellent wear resistance. The high hardness allows the tungsten carbide coating to maintain its integrity in high-stress and high-friction environments, making it less prone to wear or cracking. In addition, the tungsten carbide coating also has good corrosion resistance and high-temperature stability. In chemically corrosive environments, the tungsten carbide coating can form a protective oxide film, preventing further chemical reactions and protecting the substrate from corrosion.

[0042] The clamping mechanism 3 includes a ring 301, which is stably slidably connected to the outside of the sleeve 2. The inner wall of the ring 301 is slidably connected to the outside of the sleeve 2. A rotating rod 302 is fixedly connected inside the ring 301. The ring 301 can drive the connecting rod 303 to move through the rotating rod 302. The connecting rod 303 is rotatably connected to the outside of the rotating rod 302. During the rotation, the connecting rod 303 can drive the arc-shaped clamping plate 304 to perform corresponding actions, realizing the clamping and releasing operation of the iron can. The connecting rod 303 is rotatably connected to the inside of the sleeve 2. The arc-shaped clamping plate 304 is fixedly connected to the outside of the connecting rod 303. The arc-shaped clamping plate 304 is used to clamp and fix the iron can. An elastic component 305 is fixedly connected to the outside of the clamping mechanism 3. The elastic component 305 is used to provide force to the ring 301. The elastic component 305 includes a connecting plate 30501. 501 is the connecting component between the elastic component 305 and the clamping mechanism 3. The outer side of the connecting plate 30501 is fixedly connected to the outer side of the clamping mechanism 3. The inner side of the connecting plate 30501 is slidably connected to the arc rod 30502, which provides a sliding base for the connecting plate 30501. The outer side of the sleeve 2 is fixedly connected to the fixing plate 30503, which is used to fix one end of the arc rod 30502. The outer end of the arc rod 30502 is fixedly connected to the inner side of the fixing plate 30503. The outer side of the arc rod 30502 is sleeved with a limiting spring 30504, which provides elastic force. The outer end of the limiting spring 30504 is fixedly connected to the outer side of the fixing plate 30503, and the other outer end of the limiting spring 30504 is fixedly connected to the outer side of the connecting plate 30501.

[0043] Specifically, the tin can is placed inside the sleeve 2, the activation device is started, and the drive component 405 of the pressure mechanism 4 pushes the sliding seat 1. The sliding seat 1 slides along the base 5, and at the same time, the pressure spring 404 is compressed to provide pressure to the sliding seat 1, causing the sliding seat 1 to push the tin can. At this time, the ring 301 of the clamping mechanism 3 slides along the outside of the sleeve 2, driving the internal rotating rod 302 to move. The rotating rod 302 rotates, driving the connecting rod 303. The connecting rod 303 rotates, causing the arc-shaped clamping plate 304 connected to it to move towards the tin can and clamp it in place. During this process, the arc-shaped rod 30502 of the elastic component 305 slides within the connecting plate 30501, and the limiting spring 30504 generates elastic force according to the movement state of the ring 301, helping to maintain the stability of the clamping mechanism 3. The tin can is firmly clamped while being pushed, and the edge-rolling operation is performed.

[0044] Referring to Figure 3, the pressure applying mechanism 4 includes a guide rod 401, which is a guiding component of the pressure applying mechanism 4. The guide rod 401 is slidably connected to the inside of the sliding seat 1. A fixing block 402 is fixedly connected to one end of the guide rod 401, which is used to fix one end of the guide rod 401. A fixing plate 403 is fixedly connected to the other end of the fixing block 402, which is used to fix one end of the pressure spring 404 and the other end of the guide rod 401. The pressure spring 404 is sleeved on the outside of the guide rod 401. The function of the pressure spring 404 is to provide pressure to the sliding seat 1, so that the sliding seat 1 can maintain a certain pressure state during operation. One end of the pressure spring 404 is fixedly connected to the outside of the fixing plate 403. On one side, the outer end of the pressure spring 404 is fixedly connected to the outer side of the sliding seat 1. The bottom of the fixing block 402 is fixedly connected to the top of the base 5. The bottom of the fixing plate 403 is fixedly connected to the top of the base 5. The top of the base 5 is fixedly connected to the drive assembly 405. The drive assembly 405 is used to provide reset power to the sliding seat 1. The drive assembly 405 includes a fixing seat 40501. The fixing seat 40501 is used to fix the electric push rod 40502. The bottom of the fixing seat 40501 is fixedly connected to the top of the base 5. The electric push rod 40502 is fixedly connected inside the fixing seat 40501. The electric push rod 40502 pushes the sliding seat 1 to move. The drive end of the electric push rod 40502 is fixedly connected to the outer side of the sliding seat 1.

[0045] Specifically, the electric push rod 40502 of the drive assembly 405 is activated and retracted. The guide rod 401 acts as a guide component, and the pressure spring 404 is stretched to provide pressure to the sliding seat 1, so that the sliding seat 1 maintains a certain pressure state during operation and guides the sliding seat 1 to move along a specific direction. The sliding seat 1 slides outside the guide rod 401. When the edge rolling operation is completed, the electric push rod 40502 pushes the sliding seat 1 to move, causing the sliding seat 1 to return to its original position. The pressure spring 404 is compressed. Throughout the process, the fixing block 402 and the fixing plate 403 fix the two ends of the guide rod 401 respectively to ensure the stability of the guide rod 401. The fixing plate 403 also fixes one end of the pressure spring 404 to ensure that the pressure spring 404 functions properly.

[0046] Referring to Figures 1 and 3, an L-shaped fixed support 6 is fixedly connected to the outside of the sliding seat 1. The L-shaped fixed support 6 is used to fix the motor 7. The motor 7 is fixedly connected inside the L-shaped fixed support 6. The motor 7 is a component that provides power to the sleeve 2 and can control the rotation speed of the sleeve 2. The drive end of the motor 7 is fixedly connected inside the sliding seat 1 and rotatably connected inside the sliding seat 1. A support seat 8 is fixedly connected to the top of the base 5. The support seat 8 is used to support the second motor 9. The second motor 9 is fixedly connected to the top side of the inside of the support seat 8. The second motor 9 is a drive... The driving component for rotating the base wheel 11 includes a drive rod 10 fixedly connected to the drive end of the motor 2 9. The drive rod 10 transmits the power of the motor 2 9 to drive the base wheel 11 to rotate. The base wheel 11 is fixedly connected to the outside of the drive rod 10. The base wheel 11 is a key working component of the edge-rolling wheel device. The outer surface of the base wheel 11 is coated with a coating to enhance the wear resistance of the base wheel 11. The drive rod 10 has a keyway 12 slidably connected inside. The base wheel 11 and the drive rod 10 are connected through the keyway 12. The outside of the keyway 12 is slidably connected inside the base wheel 11.

[0047] Specifically, motor 7 starts, providing power to sleeve 2. The rotation speed of sleeve 2 causes the iron can placed inside sleeve 2 to rotate. At the same time, motor 9 starts running. The drive end of motor 9 drives drive rod 10 to rotate. Drive rod 10 transmits power to the connected base wheel 11 through the internal keyway 12, causing the base wheel 11 to rotate. Since the outer surface of the base wheel 11 is covered with a coating containing tungsten carbide particles and cobalt matrix through plasma spraying, it has high wear resistance and good bonding strength. During the rotation, it cooperates with the rotating iron can to perform edge rolling operation on the iron can.

[0048] Working principle: Pulling the connecting plate 30501 causes the ring 301 to slide. The ring 301 drives the connecting rod 303 to move through the rotating rod 302, thereby opening the arc-shaped clamping plate 304. At the same time, the limiting spring 30504 retracts. After the iron can is placed in the sleeve 2, the connecting plate 30501 is released. The limiting spring 30504 returns to its original deformation and generates elastic force. The elastic force pushes the elastic component 305 to drive the ring 301 to slide. The ring 301 then drives the connecting rod 303 to rotate through the rotating rod 302, thereby driving the arc-shaped clamping plate 304 to clamp and fix the iron can.

[0049] Motor 7 operates, driving the sleeve 2 and the internal iron can to rotate. Simultaneously, motor 9 starts, driving the drive rod 10. The drive rod 10 drives the base wheel 11, which has a special coating on its surface, to rotate via the keyway 12. At the same time, the pressure spring 404 continuously provides pressure to the sliding seat 1, pushing the sliding seat 1 to slide along the base 5. The electric push rod 40502 of the drive assembly 405 starts, pushing the sliding seat 1 to slide along the base 5. The guide rod 401 plays a guiding role, causing the iron can to be pushed. The rotating base wheel 11 and the clamped and pushed iron can cooperate to complete the edge rolling operation. After the edge rolling is completed, the electric push rod 40502 starts, pushing the sliding seat 1 to slide back along the guide rod 401. At the same time, the pressure spring 404 is compressed.
