Description
Technical Field
[0001] This utility model belongs to the field of aluminum can processing technology, and in particular relates to a vertical direct pressure groove shoulder. Background Technology
[0002] In the packaging industry, aluminum cans are widely used due to their advantages such as light weight, corrosion resistance, and recyclability. The processing quality of the shoulder groove directly affects the stability and aesthetics of the product. Currently, traditional aluminum can groove processing often uses three pressure rollers in conjunction with a shoulder tool with an angled cone. Through the mutual movement of the cone and the bearing, with the central support point as the axis, the three pressure rollers are driven to simultaneously press the aluminum can to form a groove.
[0003] However, this method has significant drawbacks: the three pressure rollers move in an arc during the pressing process, making it difficult to precisely control the dimensions of the pressed grooves, often resulting in dimensional deviations and an inability to consistently meet customer drawing requirements. Furthermore, the uneven force on the pressure rollers during the arc motion exacerbates component wear, shortens the lifespan of the groove shoulder piece, and increases equipment maintenance costs and production losses for enterprises. As the market demands increasingly higher precision and production efficiency in aluminum can processing, there is an urgent need for a new type of groove shoulder piece that can solve these problems to meet the demands of high-quality and high-efficiency production. Utility Model Content
[0004] To address the problems of existing technologies, this utility model provides a vertical direct-pressure groove shoulder tool. Through vertical direct pressure and the linear motion of the shoulder-retracting rollers, it avoids the deviations caused by the arc-shaped motion of the pressure rollers in traditional groove shoulder tools, significantly improving groove processing accuracy and work efficiency. This solves the problem in existing technologies where the three pressure rollers move in an arc during pressing, making it difficult to accurately control the dimensions of the pressed grooves, resulting in frequent dimensional deviations and an inability to consistently meet customer drawing requirements. Furthermore, the uneven force on the pressure rollers during arc-shaped motion exacerbates component wear, shortens the service life of the groove shoulder tool, and increases equipment maintenance costs and production losses for enterprises.
[0005] This utility model is implemented as follows: a vertical direct-pressure grooved shoulder device includes a bearing housing, a cylindrical support seat connected inside the bearing housing via a bearing sleeve, a large pulley fixedly fitted to the top outer wall of the cylindrical support seat, a rotating cylinder fixedly installed at the bottom of the cylindrical support seat, an intermediate shaft connected to the middle of the corresponding cylindrical support seat inside the rotating cylinder via a bearing sleeve, a support body installed at the bottom sleeve of the intermediate shaft, a locking rod slidably inserted between the intermediate shaft and the middle of the cylindrical support seat, the bottom of the locking rod being fixed to the support body sleeve, a support ring fixedly connected to the bottom center of the support body, and roller seats fixedly installed around the support body, with shoulder-reducing rollers and rollers connected inside the roller seats via bearings.
[0006] As a preferred embodiment of this invention, the roller seats are evenly distributed in a ring array around the side of the support.
[0007] This setup enables multiple rollers to create a uniform pressure distribution on the outer wall of the aluminum can, avoiding uneven local stress that could lead to inconsistent groove depths. This ensures the dimensional accuracy and consistency of the grooves around the aluminum can, thereby improving product quality stability.
[0008] As a preferred embodiment of the present invention, the middle part of the cylinder support seat is provided with a sliding cavity for the locking rod to pass through, and a compression spring is provided in the sliding cavity, the compression spring being sleeved on the locking rod.
[0009] With this setup, the compression spring extends and retracts on the locking rod, adjusting the pressure of the roller seat and providing a buffering effect during the pressing process to prevent rigid impacts from damaging the equipment and aluminum can. The pressing force can be adjusted according to the material and thickness of different aluminum cans, enhancing the adaptability and flexibility of the equipment.
[0010] As a preferred embodiment of this utility model, both ends of the cylindrical support are fixed with right-angle blocks by bolts, and a guide block is fixed on the intermediate shaft by bolts, with the right-angle blocks inserted through the guide blocks.
[0011] This setup ensures that the intermediate shaft and support maintain a stable trajectory during movement, preventing deviation or wobbling, thus guaranteeing the accuracy of the rollers vertically pressing the aluminum can and further improving the precision of the groove machining.
[0012] In a preferred embodiment of this invention, a relative motion structure is formed between the rotating cylinder and the roller seat, and the roller seat can move along the trajectory of the inner wall of the rotating cylinder to realize the vertical pressing action of the roller on the outer wall of the aluminum can.
[0013] With this setup, the roller seat moves along the trajectory of the inner wall of the rotating cylinder, realizing the vertical pressing action of the roller. Compared with the arc motion of the traditional three pressure rollers, the vertical pressing method can more accurately control the depth and width of the groove, effectively solving the problem of substandard groove size in the existing technology and improving the yield of aluminum can processing.
[0014] As a preferred embodiment of this invention, the shoulder roller is constrained by the trajectory of the inner wall of the rotating cylinder during its movement, and makes a linear motion perpendicular to the center line of the aluminum can, ensuring the dimensional accuracy of the pressing groove.
[0015] This setup assists the rollers in completing the pressing process, further ensuring the shape accuracy and dimensional stability of the groove, especially significantly improving the forming quality of the groove shoulder, thus enhancing the stability and aesthetics of the aluminum can.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By using vertical straight pressure and the linear motion of the shoulder roller, the problem of groove size deviation caused by the arc motion of the pressure roller in the traditional groove shoulder machine is solved, which significantly improves the groove processing accuracy and meets higher customer drawing requirements. The pressure adjustment function of the compression spring and the circular array distribution of the roller seats enable the equipment to adapt to the processing needs of aluminum cans of different materials and thicknesses, expand the scope of equipment application, reduce unnecessary wear and impact between components, reduce equipment failure rate, extend the service life of the groove shoulder machine, and reduce maintenance costs. The precise groove processing and stable pressing process improve the stability and aesthetics of the aluminum can. Attached Figure Description

[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0026] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] refer to Figures 1 to 7As shown in the figure, a vertical direct-pressure groove shoulder device provided by this utility model includes a bearing seat 2. A cylindrical support seat 3 is connected to the inside of the bearing seat 2 through a bearing sleeve. A large pulley 1 is fixedly sleeved on the top outer wall of the cylindrical support seat 3. A rotating cylinder 4 is fixedly installed at the bottom of the cylindrical support seat 3. An intermediate shaft 11 is connected to the middle part of the cylindrical support seat 3 inside the rotating cylinder 4 through a bearing sleeve. A support body 7 is installed at the bottom of the intermediate shaft 11. A locking rod 5 is slidably inserted between the intermediate shaft 11 and the middle part of the cylindrical support seat 3. The bottom of the locking rod 5 is fixedly sleeved with the support body 7. A support ring 14 is fixedly connected to the middle of the bottom end of the support body 7. Roller seats 8 are fixedly installed around the support body 7. A shoulder-reducing roller 10 and a roller 9 are connected to the inside of the roller seat 8 through a bearing.
[0028] Specifically, the roller seats 8 are evenly distributed in a ring array around the side of the support body 7.
[0029] By adopting the above solution, multiple rollers 9 can form a uniform pressure distribution on the outer wall of the aluminum can, avoiding the problem of inconsistent groove depth caused by uneven local force, ensuring the dimensional accuracy and consistency of the grooves in the circumferential direction of the aluminum can, and improving the stability of product quality.
[0030] Specifically, the cylinder support 3 has a sliding cavity in the middle for the locking rod 5 to pass through, and a compression spring 6 is provided in the sliding cavity, which is sleeved on the locking rod 5.
[0031] Using the above scheme, the compression spring 6 extends and retracts on the locking rod 5 to adjust the pressure of the roller seat 8, providing a buffering effect during the pressing process to avoid damage to the equipment and aluminum can from rigid impact. The pressing force can be adjusted according to the material and thickness of different aluminum cans to enhance the adaptability and flexibility of the equipment.
[0032] Specifically, both ends of the cylindrical support 3 are fixed with right-angle blocks 13 by bolts, and the intermediate shaft 11 is fixed with guide blocks 12 by bolts, with the right-angle blocks 13 inserted through the guide blocks 12.
[0033] By adopting the above scheme, it is ensured that the intermediate shaft 11 and the support 7 maintain a stable trajectory during the movement, preventing deviation or shaking, thereby ensuring the accuracy of the roller 9 vertically pressing the aluminum can and further improving the groove processing accuracy.
[0034] Specifically, the rotating cylinder 4 and the roller seat 8 form a relative motion structure, and the roller seat 8 can move along the trajectory of the inner wall of the rotating cylinder 4 to realize the vertical pressing action of the roller 9 on the outer wall of the aluminum can.
[0035] Using the above scheme, the roller seat 8 moves along the trajectory of the inner wall of the rotating cylinder 4 to realize the vertical pressing action of the roller 9. Compared with the arc motion of the traditional three pressure rollers, the vertical pressing method can more accurately control the depth and width of the groove, effectively solving the problem of groove size not meeting the standards in the existing technology and improving the yield of aluminum can processing.
[0036] Specifically, the shoulder roller 10 is constrained by the trajectory of the inner wall of the rotating cylinder 4 during its movement, and makes a linear motion perpendicular to the center line of the aluminum can to ensure the dimensional accuracy of the pressing groove.
[0037] By adopting the above scheme, the auxiliary roller 9 completes the pressing process, further ensuring the shape accuracy and dimensional stability of the groove, especially significantly improving the forming quality of the groove shoulder, thereby enhancing the stability and aesthetics of the aluminum can.
[0038] The working principle of this utility model:
[0039] During use, the motor drives the large pulley 1 to rotate via a belt. The large pulley 1 drives the cylinder support seat 33 and the rotating cylinder 4 to make circular motion. When the mold plate moves towards the fixed turntable, the aluminum can contacts the support ring 14. In the initial state, the roller seat 8, roller 9, and shoulder roller 10 do not contact the outer wall of the aluminum can under the action of centrifugal force. As the mold plate approaches, the roller seat 8 moves along the trajectory of the inner wall of the rotating cylinder 4. The compression spring 6 is compressed and extended on the locking rod 5 to adjust the pressure. At this time, the roller 9 presses vertically against the outer wall of the aluminum can, and the shoulder roller 10 makes a linear motion perpendicular to the center line of the aluminum can. The two work together to press out a precise groove. The right-angle block 13 and the guide block 12 assist the movement of the components. The bearing seat 2 and the cylinder support seat 3 ensure structural stability and ensure that the entire pressing process is stable and precise. Through vertical pressing and the linear motion of the shoulder roller 10, the problem of groove size deviation caused by the arc motion of the traditional groove shoulder press roller is solved, which significantly improves the groove processing accuracy, meets higher customer drawing requirements, and improves work efficiency and production efficiency.
