Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a slitting machine with a dual shearing system. Background Technology

[0002] Aluminum foil, due to its good ductility, excellent water and oxygen barrier properties, and abundant raw material reserves, is widely used in food, beverages, cigarettes, pharmaceuticals, packaging, and other products. Aluminum foil with a thickness of 0.10mm or less is typically processed using a double-sheet rolling process as shown in the invention patent CN104858233B. This involves coating two aluminum foil sheets with lubricating oil between them, then rolling them together, followed by edge trimming and separation using a slitting machine. The separation process uses two take-up rollers, which can be horizontal or vertical depending on their relative positions. Traditional slitting machines only have one shearing system. The double-sheet rolled aluminum foil strip must first undergo edge trimming by the shearing system before being separated by the take-up rollers. When the thickness of the laminated aluminum foil at the entry point reaches approximately 0.01mm, edge trimming can result in aluminum powder, curling, and wrinkling at the foil edges. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a slitting machine with a dual shearing system to improve the technical problem of low yield of aluminum foil produced by double-sheet rolling process.

[0004] To achieve the above-mentioned objective, the technical solution provided by this utility model is as follows: A slitting machine with a dual shearing system includes a housing, an unwinding roller is provided inside the housing, a separating roller group is provided downstream of the unwinding roller, and the separating roller group is connected to a left shearing system and a right shearing system arranged in parallel. Both shearing systems are provided with a cutting shaft with a radial cutting blade, a welding roller and a winding roller in sequence.

[0005] Furthermore, the left shearing system includes a left cutting shaft, a left steering roller, a left welding roller, and a left take-up roller arranged in sequence; the right shearing system includes a right steering roller, a right cutting shaft, a right welding roller, and a right take-up roller arranged in sequence.

[0006] Furthermore, the unwinding roller is coaxially connected to the output end of the unwinding motor, and the left take-up roller and the right take-up roller are each independently connected to a winding motor.

[0007] Furthermore, the left cutting shaft and the left steering roller are arranged symmetrically with the right steering roller and the right cutting shaft; the left welding roller and the left winding roller are arranged symmetrically with the right welding roller and the right winding roller.

[0008] Furthermore, the cutting shaft is a cylindrical body with at least two guide rails parallel to each other on its surface along its axis. The cutting blade includes an annular cutter that is sleeved on the outside of the cutting shaft and extends into the inside of the cutting shaft through the guide rails. A nut is coaxially provided on the inside of the cutting shaft, and a threaded rod is sleeved on the nut. The threaded rod passes through the end of the cutting shaft.

[0009] Furthermore, the end of the cutting shaft is coaxially connected to the output shaft of the servo motor, and the servo motor is fixedly mounted on the end face of the cutting shaft.

[0010] Furthermore, the housing is provided with a partition that fits with the cutting blade with a clearance. A distance sensor is fixedly installed on the left side of the partition. The distance sensor measures the position of the cutting blade on the cutting axis from the side facing the cutting blade. The distance sensor is electrically connected to the controller.

[0011] Furthermore, the housing has an opening in the side wall downstream of the cutting roller, and a waste removal roller is provided inside the opening. A waste removal motor is coaxially provided on the waste removal roller, and the waste removal motor is electrically connected to the controller.

[0012] Furthermore, a touch screen is provided on the outside of the housing, and the touch screen is electrically connected to the controller.

[0013] Furthermore, the housing is provided with a connecting seat adapted to the unwinding roller and / or the winding roller. The top surface of the connecting seat is provided with a connecting groove adapted to the unwinding roller and / or the winding roller. The side is connected to an arc-shaped fixing member by a hinge. The end of the arc-shaped fixing member away from the hinge is attracted to the connecting seat by an electromagnet. The coil of the electromagnet is electrically connected to the controller.

[0014] The advantages and beneficial effects of this utility model are as follows: Through the parallel design of the left and right shearing systems, the composite and slitting operations of the double-sheet rolling process can be achieved synchronously. The left and right systems adopt a centrally symmetrical and mirror-symmetrical design, with mechanical balance to offset the vibration energy during high-speed operation, while shortening the transmission path. The cutting blade uses a guide rail limiting and threaded rod adjustment mechanism, combined with a distance sensor to form a position feedback closed loop. The electromagnetic locking mechanism allows for faster roller replacement than traditional bolts. The waste removal roller group located downstream of the cutting section removes slitting waste through a controller, keeping the machine casing clean and reducing waste interference with production.

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0022] Example 1

[0023] like Figure 1-4 This embodiment provides a slitting machine with a dual shearing system, including a housing 1. An unwinding roller 14 is installed inside the housing 1 and driven by an unwinding motor 57. A separating roller group 2 is located downstream of the unwinding roller to guide two sheets of aluminum foil into the left and right shearing systems. The left shearing system includes a left cutting shaft 31, a left steering roller 32, a left welding roller 33, and a left take-up roller 34 arranged sequentially; the right shearing system includes a right steering roller 42, a right cutting shaft 41, a right welding roller 43, and a right take-up roller 44 arranged sequentially. The left cutting shaft 31 and left steering roller 32 in the left shearing system are centrally symmetrically arranged with the right steering roller 42 and right cutting shaft 41 in the right shearing system. The left welding roller 33 and left take-up roller 34 are symmetrically arranged with the right welding roller 43 and right take-up roller 44 along their left and right axes. The left take-up roller 34 and right take-up roller 44 are each independently connected to a winding motor 58.

[0024] Both the left and right cutting shafts are cylindrical, with two axially oriented guide rails 5 on their surfaces. The annular cutter 51 is connected to the nut 52 inside the cutting shaft via the guide rails. A threaded rod 53 passes through the end of the cutting shaft and is driven by a servo motor 54. The nut 52 is fitted onto the left side of the threaded rod 53, enabling closed-loop adjustment of the cutter's axial position. A partition 55 is tangentially arranged on the left and right cutting shafts. A distance sensor 56 is installed on the left side of the partition 55 to monitor the cutter position in real time and provide feedback to the controller.

[0025] An opening 6 is provided on the side wall of the casing downstream of the cutting shaft, and a waste cleaning roller 61 is provided inside it. The waste cleaning roller 61 is driven by a waste cleaning motor 62, and the linkage controller automatically cleans up the waste.

[0026] The unwinding motor 57, winding motor 58, waste removal motor 62, and servo motor 54 are all coaxially connected to their respective rollers. These four types of motors, along with the distance sensor 56, are electrically connected to the left side of the controller. The controller is also externally mounted on the machine housing 1 via a touchscreen 7 for parameter setting and status monitoring. The controller is implemented using a programmable logic controller (PLC). The distance sensor can be an infrared rangefinder, laser rangefinder, etc., with its output facing the side wall of the ring cutter 51. It feeds back the distance measurement results between the sensor and the cutter to the controller for real-time monitoring. When a deviation of ±0.2mm occurs, the controller adjusts the servo motor for fine-tuning.

[0027] Example 2

[0028] A slitting machine with a dual shearing system differs from Embodiment 1 in that four guide rails 5 are provided on the surfaces of the left cutting shaft 31 and the right cutting shaft 41, and a damping bearing is added to the end of the cutting shaft, which is flexibly connected to the output shaft of the servo motor 54 to reduce vibration interference during high-speed adjustment. The partition 55 is made of honeycomb board to improve vibration isolation performance.

[0029] Example 3

[0030] A slitting machine with a dual shearing system differs from Embodiment 1 in that a connecting seat 11 adapted to the unwinding roller 14 and two take-up rollers is provided inside the machine housing. The lower part of the connecting seat 11 is fixed to the inner wall of the machine housing 1, while the upper part rotates around the lower part via a hinge. A radial groove is cut into the inner part of the connecting seat 11, and a bearing can be installed in the groove. The roller passes through the bearing and rotates with the connecting seat. The electromagnet 13 of the connecting seat 11 is linked to the controller, and the touch screen 7 provides a "one-click roller change" function. When changing rollers, the electromagnet automatically de-energizes and releases the arc-shaped fixing piece 12, eliminating the need for manual bolt removal.

[0031] The working principle of this invention is as follows: after the double-sheet aluminum foil is unwound by the unwinding roller 14, the separating roller group 2 guides the aluminum foil strip into the parallel left and right shearing systems respectively. The two systems synchronously perform cutting, welding, and winding actions, achieving synchronous slitting and separation of the double-sheet aluminum foil. The centrally symmetrical rollers counteract the vibration energy during high-speed operation. The mirror-symmetrical rollers shorten the transmission path and reduce power loss. Secondary slitting in traditional processes is avoided. The distance sensor 56 monitors the tool position, and the data is fed back to the controller to form a closed-loop regulation. The aluminum powder and waste generated during cutting are isolated by the partition 55. The downstream waste cleaning roller 61 is driven by the waste cleaning motor 62 to automatically clean up the waste and keep the machine clean. The connecting seat 11 controls the opening and closing of the arc-shaped fixing part 12 through the electromagnet 13 to achieve quick unlocking of the rollers for easy replacement. The touch screen 7 integrates parameter settings and supports preset slitting specification templates, reducing the complexity of operation.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
