AI Technical Summary
Existing slitting machines require manual clamping of the roll material during use, making it difficult to ensure that the center of the roll material coincides with the cutting curve. Furthermore, they lack air shaft assemblies that can adapt to roll materials with different inner diameters, increasing equipment costs and management difficulties.
An automatic feeding mechanism including an air shaft assembly and a clamping assembly was designed. The air bladder of the air shaft assembly expands to push the key strip to extend radially and clamp the inner wall of the roll. Combined with the limiting plate of the electric push rod clamping assembly, the roll end face is opened to achieve automatic fixing and correction of the roll material. The roll material position is adjusted in real time with the correction device.
It enables automated and rapid clamping and unloading of roll materials, ensuring that the center of the roll material is aligned with the cutting curve, reducing equipment costs, and improving production efficiency and product quality.

This can easily lead to roll material deviation. Furthermore, for roll materials with different inner diameters, when there is a lack of air shaft assemblies, it may be necessary to prepare various fixed shaft cores of different specifications to adapt to them, which increases equipment costs and management difficulties. This phenomenon has become a problem that urgently needs to be solved by people in this field. Utility Model Content

Detailed Implementation
[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0022] Please see Figure 1-6 This utility model provides a technical solution: an automatic feeding mechanism for a slitting machine, including a frame 1. The frame 1 is frame-shaped. Two sets of support plates 2 are fixedly connected to one side of the upper part of the frame 1. An air shaft assembly 3 is arranged between the two sets of support plates 2. The air shaft assembly 3 includes a shaft core 302 connected to the two sets of support plates 2 through bearings. Shaft ends 301 are fixedly connected to the outside of both ends of the shaft core 302. An air nozzle 303 is installed at one end of the shaft core 302, and the other end of the air nozzle 303... It can connect to an external air source for inflation and deflation, and is equipped with a one-way valve to prevent gas backflow. An air bladder 304, made of high-strength rubber, is fitted over the shaft core 302. The air bladder 304 is connected to an air nozzle 303. A shaft sleeve 305 is fitted over the shaft core 302, with the outer surface of the air bladder 304 fitting snugly against the inner wall of the shaft sleeve 305. End caps are provided at both ends of the shaft core 302 to fix the air bladder 304 and the shaft sleeve 305. The air bladder 304 and... Both the shaft core 302 and the end cap have sealing elements on their contact surfaces to prevent air leakage from the airbag 304, and fasteners are provided to secure them. A key strip 306 extending to the outside is slidably connected inside the shaft sleeve 305. The airbag 304 is fixedly connected to the key strip 306. After the airbag 304 is inflated, it can push the key strip 306. At this time, the key strip 306 extends radially along the keyway opened at the shaft sleeve 305, and the extended key strip 306 interacts with the coil... The inner wall of the drum fits snugly, making it easy to fix the drum and allowing the drum and shaft core 302 to rotate synchronously. After the compressed air in the air bladder 304 is released through the air nozzle 303, the air bladder 304 retracts under its own elasticity or the extension and contraction of the return spring. The key bar 306 retracts into the shaft sleeve 305, thereby releasing the fixation of the drum and allowing the drum to be easily removed. The rapid clamping and unloading of the roll material is achieved by inflating and deflating the air shaft assembly 3, thereby realizing the automated operation of feeding.
[0023] A clamping assembly 4 is provided on the outside of the shaft end 301. The clamping assembly 4 includes two sets of connecting sleeves 401 fixedly connected to the outer surface of the shaft end 301. A limit rod 402 is fixedly connected to the side of the two sets of connecting sleeves 401 near the roll material. Two sets of connecting plates 403 are also fixedly connected to the side of the two sets of connecting sleeves 401 near the roll material. An electric push rod 404 is installed on one side of the two sets of connecting plates 403. The output end of the electric push rod 404 is connected to a limit plate 405. The limit plate 405 is slidably connected to the limit rod 402. A clamping sleeve 406 is fixedly connected to the side of the limit plate 405 near the shaft end 301. When the air expansion shaft assembly 3 expands the inside of the roll material, the electric push rod 404 is activated. The output end of the electric push rod 404 can push the limit plate 405 and the clamping sleeve 406 to move, so that the clamping sleeve 406 can move and expand both ends of the roll material to form a double fixation.
[0024] A cabinet 5 is installed on the side of the frame 1 near the support plate 2. A leveling component 6 is set on the top of the cabinet 5. A first roller 601, a second roller 602, a third roller 603, a fourth roller 604 and a fifth roller 605 are arranged on the top of the leveling component 6 from left to right. The fourth roller 604 is located above the third roller 603 and the fifth roller 605. The material is guided by the multi-roller guide of the leveling component 6, and wrinkles can be eliminated before entering the slitting station.
[0025] A blade holder assembly 7 is located on the side of the flattening component 6 above the cabinet 5 and away from the roll material. The blade holder assembly 7 is equipped with a bracket 701 fixed to the top of the cabinet 5. The bracket 701 is equipped with an upper disc blade 702 and a lower disc blade 703, with the lower disc blade 703 located above the upper disc blade 702. The upper disc blade 702 and the lower disc blade 703 of the blade holder assembly 7 can cut the material.
[0026] A touch screen 8 is installed on the top of the cabinet 5. The touch screen 8 is an advanced resistive ultra-high-definition touch screen with a clear screen and sensitive buttons. All operating functions of the machine can be realized on the touch screen 8.
[0027] One side of one of the support plates 2 is equipped with a correction device 9. The correction device 9 consists of a detection unit, a control unit, and an electric slide rail. The sensor in the detection unit scans the edge of the material and transmits the position signal to the controller. The controller compares the set position with the actual position and generates the correction amount. After being driven by the servo motor in the electric slide rail, the nut moves linearly along the lead screw and drives the slider to move. After reaching the desired position, the motor can be stopped, thereby moving the position of the roll material to prevent deviation during feeding.
[0028] Working principle: The roll is inserted into the air shaft assembly 3 and inflated through the air nozzle 303. The air bladder 304 expands and pushes the key bar 306 to extend radially, clamping the inner wall of the roll. The electric push rod 404 of the clamping assembly 4 pushes the limit plate 405 to open the end face of the roll, completing the double fixation. When the roll is fed, the sensor of the correction device 9 monitors the edge position in real time and adjusts the lateral position of the roll through the electric slide rail to ensure centering. The material is guided by the multi-roller guide of the flattening assembly 6 to eliminate wrinkles and enter the slitting station. The upper disc cutter 702 and the lower disc cutter 703 of the cutter holder assembly 7 cut the material. After slitting is completed, the air shaft assembly 3 is deflated, the key bar 306 retracts, the clamping assembly 4 is released, and the roll can be quickly removed.
