Description

Technical Field

[0001] This invention relates to the field of rolling equipment technology, and more specifically to an automated rolling equipment for forming metal packaging cans. Background Technology

[0002] Metal packaging is a container made of thin metal sheets (tinplate, aluminum, etc.). Its core advantages are high barrier properties, high strength, and unlimited recyclability. It is widely used in food, beverages, daily chemicals, and industrial products.

[0003] In the manufacturing process of metal packaging, specialized rolling equipment is required to roll thin metal sheets into circles to form cans. Currently, conventional rolling equipment generally consists of two or more sets of rotatable rollers. The gap between these two sets of rollers is adapted to the thin metal sheet. When rolling, simply place the thin metal sheet into the gap between the rollers, and then drive the rollers to rotate, causing them to move the thin metal sheet, thus rolling the sheet into a circle.

[0004] However, the aforementioned rolling equipment has certain drawbacks. During the rolling process, the rolled metal sheet is fitted onto a rolling roller. When removing it, it needs to be taken out from its end along the axial direction of the rolling roller. During this process, the entire rolling equipment needs to be completely stopped, which greatly affects the production rhythm and results in low production efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automated rolling equipment for forming metal packaging cans to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: an automated rolling equipment for forming metal packaging cans, comprising: a frame and a rolling assembly, wherein the rolling assembly includes a drive roller, an auxiliary roller and a rolling roller, wherein the drive roller, the auxiliary roller and the rolling roller are all rotatable, and the drive roller can rotate actively, wherein a thin metal sheet can extend into the gap between the drive roller, the auxiliary roller and the rolling roller, and bend under the drive roller and then be fitted onto the rolling roller; there are two sets of rolling rollers, which can alternately cooperate with the auxiliary roller and the drive roller to roll the thin metal sheet.

[0007] Furthermore, the drive roller, auxiliary roller, and winding roller are all hollow structures, with the winding roller positioned above the auxiliary roller and drive roller.

[0008] Furthermore, the drive roller is equipped with a drive motor, and the drive motor and the drive roller shaft are connected by a first sprocket and a first chain.

[0009] Furthermore, a mounting base is installed on the frame, and both the drive roller and the auxiliary roller are rotatably mounted on the side of the mounting base.

[0010] Furthermore, the mounting base has a groove in the middle, and a slider is slidably installed in the groove. The shaft of the auxiliary roller is rotatably installed in the middle of the slider. An adjusting screw is threaded on the mounting base, and the end of the adjusting screw is rotatably connected to the slider. At the same time, the rotation of the adjusting screw will drive the slider to slide in the groove and drive the auxiliary roller to move synchronously.

[0011] Furthermore, an adjustment frame is rotatably mounted on the side of the mounting base, and two sets of winding rollers are rotatably mounted on the side of the adjustment frame and are symmetrically distributed. A brake motor is mounted on the other side of the mounting base, and the motor is driven to the rotating shaft of the adjustment frame through a second sprocket and a second chain.

[0012] Furthermore, a limit component is installed at the end of the roll away from the adjusting frame to prevent material from falling off the roll when the adjusting frame rotates.

[0013] Furthermore, the limiting assembly includes a connecting seat, and the end of the roll away from the adjusting frame is provided with an opening. The connecting seat is fixedly installed on the end of the roll by screws. A limiting rod is rotatably installed on the end of the connecting seat away from the roll. When the roll is close to the drive roller and the auxiliary roller, the limiting rod is in a cross state with the axis of the roll. When the roll is at its farthest distance from the drive roller and the auxiliary roller, the limiting rod is collinear with the axis of the roll.

[0014] Furthermore, a stop is installed at the end of the connecting seat away from the winding roller, the limiting rod is rotatably connected to the stop, and a counterweight is installed in the middle of the limiting rod.

[0015] The technical effects and advantages of this invention are as follows: This invention, by setting up two sets of rotating rollers that can work alternately, allows for quick switching to the other roller when a metal roll is mounted on the surface of one roller. This process saves downtime and restart time, effectively improving production efficiency.

[0016] Furthermore, during use, the limiting component will automatically limit the metal roll on the winding roller during the switching process, and automatically contact the limit after the switching is completed, thereby effectively ensuring working stability and further ensuring production efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative and are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figure 1-5 This invention provides an automated rolling equipment for forming metal packaging cans, comprising: The frame 1 and the winding assembly 2 include a drive roller 21, an auxiliary roller 22 and a winding roller 23. The drive roller 21, the auxiliary roller 22 and the winding roller 23 are all rotatable, and the drive roller 21 can rotate actively. The metal sheet can be inserted through the gap between the drive roller 21, the auxiliary roller 22 and the winding roller 23, and bend under the drive roller 21 and then be sleeved on the winding roller 23. There are two sets of winding rollers 23, which can be alternately used with the auxiliary roller 22 and the drive roller to roll the metal sheet into a circle.

[0021] In this way, when using it, you only need to put the metal sheet to be rolled into the gap between the rolling roller 23, the auxiliary roller 22 and the drive roller 21, and then let the drive roller 21 rotate to drive the metal sheet to bend, thereby achieving rolling. After rolling is completed, another rolling roller 23 can be directly switched to work, which can greatly reduce the downtime caused by unloading and effectively improve processing efficiency.

[0022] The drive roller 21, auxiliary roller 22 and winding roller 23 are all hollow structures, which can reduce weight and ensure structural stability. The winding roller 23 is positioned above the auxiliary roller 22 and drive roller 21 to facilitate unloading.

[0023] The drive roller 21 is equipped with a drive motor 3, and the drive motor 3 and the drive roller 21 shaft are connected by a first sprocket 4 and a first chain 5. Thus, by simply starting the drive motor 3, the drive roller 21 can be rotated through the first sprocket 4 and the first chain 5.

[0024] A mounting base 11 is installed on the frame 1, and the drive roller 21 and the auxiliary roller 22 are rotatably mounted on the side of the mounting base 11.

[0025] The mounting base 11 has a groove 12 in the middle, and a slider 13 is slidably installed in the groove 12. The shaft of the auxiliary roller 22 is rotatably installed in the middle of the slider 13. An adjusting screw 14 is threaded on the mounting base 11, and the end of the adjusting screw 14 is rotatably connected to the slider 13. At the same time, the rotation of the adjusting screw 14 will drive the slider 13 to slide in the groove 12 and drive the auxiliary roller 22 to move synchronously. Thus, by simply rotating the adjusting screw 14 to drive the slider 13 to move, the auxiliary roller 22 can be moved, thereby adjusting the gap between the auxiliary roller 22 and the winding roller 23 and the drive roller 21 to adapt to various metal sheets of different thicknesses.

[0026] An adjusting frame 15 is rotatably mounted on the side of the mounting base 11. Two sets of winding rollers 23 are rotatably mounted on the side of the adjusting frame 15 and are symmetrically distributed. A brake motor 6 is mounted on the other side of the mounting base 11. The motor 6 is driven to the rotating shaft of the adjusting frame 15 by a second sprocket 7 and a second chain 8.

[0027] Thus, by simply starting the brake motor 6, the second sprocket 7 and the second chain 8 can drive the adjusting frame 15 to rotate, thereby driving the two winding rollers 23 to switch and achieve alternating operation.

[0028] A limit component 9 is installed at the end of the winding roller 23 away from the adjusting frame 15, which can prevent the material on the winding roller 23 from falling off when the adjusting frame 15 rotates.

[0029] The limiting component 9 includes a connecting seat 91. The end of the winding roller 23 away from the adjusting frame 15 has an opening. The connecting seat 91 is fixedly installed on the end of the winding roller 23 by screws. A limiting rod 92 is rotatably installed on the end of the connecting seat 91 away from the winding roller 23. When the winding roller 23 is close to the drive roller 21 and the auxiliary roller 22, the limiting rod 92 is in a cross state with the axis of the winding roller 23. When the winding roller 23 is at its farthest distance from the drive roller 21 and the auxiliary roller 22, the limiting rod 92 is collinear with the axis of the winding roller 23.

[0030] A stop block 93 is installed at the end of the connecting seat 91 away from the winding roller 23. The limiting rod 92 is rotatably connected to the stop block 93, and a counterweight 94 is installed in the middle of the limiting rod 92.

[0031] Thus, during the rotation of the adjusting frame 15, the limiting rod 92 on the side of the lower winding roller 23 will rotate downward under the action of the counterweight 94, thus intersecting with the axis of the winding roller 23. At this time, if the material on the winding roller 23 slides out from the end of the winding roller 23, it will be blocked by the limiting rod 92 until the winding roller 23 rotates to the top with the adjusting frame 15. At this time, the force direction of the limiting rod 92 changes by 180 degrees, thus reversing. However, as shown in the figure, at this time, the limiting rod 92 will be blocked by the stop block 93, thus maintaining a coaxial posture with the axis of the winding roller 23. At this time, the material on its surface can be directly taken out from its end.

[0032] Therefore, the complete workflow is as follows: First, start the brake motor 6 to drive the adjusting frame 15 to rotate, thereby moving the winding roller 23 closer to the drive roller 21 and the auxiliary roller 22. Then, feed the metal sheet to be rolled into the gap between the winding roller 23, the drive roller 21, and the auxiliary roller 22, and start the drive motor 3 to drive the drive roller 21 to rotate, thereby continuously driving the metal sheet in. During this process, the metal sheet is bent by the rolling force, thus achieving rounding. After rounding, the product is placed on the winding roller 23 (the principle is existing technology and will not be described in detail in this invention). At this point, if the machine is stopped directly... Feeding and restarting the machine takes a lot of time. With the improvement of this invention, there is no need to stop the machine. Just start the brake motor 6 to make it drive the adjusting frame 15 to rotate 180 degrees. This will cause the two sets of winding rollers 23 to switch alternately. At this time, the winding roller 23 with the metal roll on its surface will be at the top. The other set of winding rollers 23 will cooperate with the drive roller 21 and the auxiliary roller 22 again. At this time, the metal sheet can continue to be fed. During its processing, the metal roll on the top winding roller 23 can be removed. By working alternately in this way, the time of stopping and restarting the machine and feeding can be saved, thereby greatly improving production efficiency.

[0033] Furthermore, during the rotation of the winding roller 23, the limiting rod 92 at its end, when not in the highest position, will rotate under the action of gravity to maintain its orientation intersecting the axis of the winding roller 23. This prevents the metal drum from detaching from the winding roller 23 due to vibration or other factors when the adjusting frame 15 rotates. Moreover, when the drum rotates to the highest position (refer to the height, left and right directions), Figure 1 The force on the limiting rod 92 changes, and it becomes collinear with the axis of the winding roller 23, thereby releasing the limit on the metal drum. The entire process is completely seamless, which not only makes the structure simple but also effectively ensures the stability of production.

[0034] In summary, by setting up two sets of rotating rollers 23 that can work alternately, the present invention can quickly switch to the other rotating roller 23 when a metal roll is fitted on the surface of one rotating roller 23. Throughout the process, the time for stopping and restarting the machine can be saved, effectively improving production efficiency.

[0035] Furthermore, during use, when the winding roller 23 is switching, the limiting component 9 will automatically limit the metal roll on the winding roller 23. After the switching is completed, it will automatically contact the limit, thereby effectively ensuring working stability and further ensuring production efficiency.

[0036] It should be noted that the above-mentioned rolling equipment can be further optimized by adding a positioning component. This positioning component includes an electric push rod, which is mounted on the frame 1. The movable end of the electric push rod is fixed with a positioning pin. Positioning holes are opened on the sides of the mounting base 11 and the adjusting frame 15. When the rolling roller 23 rotates to the working position, the electric push rod will trigger and drive the positioning pin to simultaneously insert into the positioning hole between the mounting base 11 and the adjusting frame 15. Furthermore, before the brake motor starts, the electric push rod will drive the positioning pin to slide out of the positioning hole. In this way, the stability of the rolling roller 23 can be ensured during the entire operation of the rolling equipment.

[0037] In addition, an infrared sensor is installed between the adjusting frame 15 and the mounting base 11. When the winding roller 23 rotates to the working position, the infrared sensor will be triggered to provide feedback to the drive motor 3 and avoid rotation error of the adjusting frame 15.

[0038] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention. Other structures can be referred to with ordinary designs. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
