Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum foil production equipment, and specifically relates to a winding device and an auxiliary disassembly and assembly tooling for a flattening roller of an aluminum foil slitting machine. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Its stamping effect is similar to that of pure silver foil, hence it is also called imitation silver foil. Because aluminum is soft, malleable, and has a silvery-white luster, if the rolled sheet is mounted on offset paper with substances such as sodium silicate to create aluminum foil sheets, it can be printed on. However, aluminum foil itself is prone to oxidation and darkening; rubbing and touching will cause the color to fade, making it unsuitable for hot stamping on book covers and other items intended for long-term preservation. Aluminum foil can be classified into thick foil, single-zero foil, and double-zero foil according to thickness. Double-zero foil is foil with two zeros after the decimal point when its thickness is measured in mm; it is typically aluminum foil with a thickness of less than 0.0075 mm.

[0003] For example, patent application number CN202410064786.7 discloses a method for preparing high-strength aluminum foil for batteries, the method comprising:

[0004] S101 Raw Material Melting and Casting: The raw materials are put into the melting furnace according to the proportion, the temperature of the aluminum melt is controlled at 710-740℃, the hydrogen content in the melt is ≤0.12ml / 100gAl, and aluminum coils with a thickness of 6.0-7.0mm are obtained by casting and rolling.

[0005] S102 Cold Rolling: The aluminum coil obtained in step S101 is cold rolled once to a thickness of 3.6-4.2 mm.

[0006] S103 Annealing: The aluminum coil obtained in step S102 is subjected to homogenization annealing at 540-560℃ for 24-26 hours.

[0007] S104 Secondary cold rolling: The aluminum coil obtained in step S103 is cold rolled in 4 passes to a thickness of 0.20-0.24 mm.

[0008] S105 Foil Rolling: The aluminum coil obtained in step S104 is rolled through 4 passes to obtain aluminum foil with a thickness of 0.010-0.015 mm.

[0009] S106 Fine Slitting: The aluminum foil obtained in step S105 is slitting into small rolls by a slitting machine, then subjected to corona treatment, and finally finely cut by a precision cutter to obtain aluminum foil of the predetermined specifications.

[0010] In the prior art, a slitting machine is used in step S106. The slitting machine can perform the following process: separating two layers of double-zero aluminum foil, adjusting the winding tension, and cutting the aluminum foil into the corresponding width.

[0011] The existing aluminum foil slitting machine's winding device includes a frame, a welding machine track positioned at the top front of the frame and running horizontally, a welding machine on the track capable of horizontal movement, an electric hoist above the frame capable of forward and backward movement, and two winding units arranged side-by-side at the front of the frame. Each winding unit includes a winding shaft and two flattening rollers on its upper and lower sides. The electric hoist is equipped with a sling for suspending the winding shaft or flattening rollers. Both the winding shaft and flattening rollers are positioned horizontally. The two ends of the winding shaft are respectively located on two winding shaft seats on either side of the frame. A discharge arm for forward feeding the winding shaft is located on the frame and directly below the winding shaft. The discharge arm, mounted on the frame and capable of forward and backward movement, includes a horizontally oriented crossbeam and two support arms at its front ends. The support arms, positioned horizontally, are located below the rotating shaft of the winding shaft, and their front ends have grooves that mate with the corresponding ends of the rotating shaft. The two ends of the flattening roller are respectively located on two flattening roller seats on both sides of the frame, and the flattening roller seats can move up and down.

[0012] For example, patent application number CN201120322468.4 discloses a follow-up control device for the flattening roller of a vertical aluminum foil slitting machine, including a frame, a drive-side cylinder, an operating-side cylinder, solenoid valves A and B, a pneumatic E / P proportional valve, an air brake, and a control system; the cylinder bodies of the drive-side cylinder and the operating-side cylinder are respectively fixed on the drive-side and operating-side frames, and their piston rods are respectively fixed on the outer edges of the flattening roller synchronous shaft protruding from the drive-side and operating-side frames; linear guide rails for lifting and guiding the flattening roller are fixed on the inner sides of the drive-side and operating-side frames. An air brake is installed on the flattening roller support. The air brake consists of a shaft clamp that grips the synchronous shaft of the flattening roller and a small cylinder that controls the tension of the shaft clamp. The cylinder body of the small cylinder is fixed on a brake plate at the opening of the shaft clamp, and its piston rod is connected to the end of the other brake plate of the shaft clamp. The drive-side cylinder and the operating-side cylinder are connected to the pneumatic valve station through solenoid valve A and pneumatic E / P proportional valve, respectively. The small cylinder is connected to the pneumatic valve station through a pressure reducing valve and solenoid valve B, respectively. The pneumatic valve station is connected to an air source. The signal control terminals of the pneumatic E / P proportional valve and the solenoid valve are connected to the control system.

[0013] The existing aluminum foil slitting machine's winding device has four flattening rollers. Since the thickness of double-zero aluminum foil is very thin, the flattening rollers need frequent replacement to avoid wrinkles and breakage. They may need to be replaced every one or two shifts. During the actual replacement of the flattening rollers, the applicant encountered a problem: due to the limitations of the welding machine track (the top flattening roller is very close to the welding machine track, and the bending radius of the electric hoist's sling cannot be too large (i.e., the angle of pull cannot be too large)), the top flattening roller could not be directly lifted and replaced using the electric hoist. The remaining three flattening rollers could be disassembled and reassembled with the assistance of an electric hoist.

[0014] The flattening roller weighs 105kg and requires two people to lift it to the installation location. The following problems arose during the replacement of the top flattening roller:

[0015] 1. After the lifting platform is raised, each person needs to bear an average weight of 52.5 kg during the lifting process (forward and backward), which poses a significant safety hazard;

[0016] 2. Relying on manual handling and replacement is inefficient and takes up production time, usually requiring 120 minutes. Summary of the Invention

[0039] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] See Figure 1-2Example 1 provides an auxiliary disassembly and assembly fixture for a flattening roller, including multiple disassembly fixtures 9. The multiple disassembly fixtures 9 are arranged side-by-side on the front side of the crossbeam 71 of the top discharge arm 7. The disassembly fixtures 9 are arranged in the front-rear direction, with their rear ends detachably (via a connecting part) mounted on the crossbeam 71. Their upper front side has a U-shaped groove 93 for supporting the flattening roller 5. The U-shaped groove 93 is arranged in the left-right direction, located above and in front of the crossbeam 71, and has a buffer protective layer 94 on its inner side to prevent scratching the flattening roller 5. The groove width is greater than the diameter of the flattening roller 5. During slitting by the slitting machine, the disassembly fixtures 9 are removed. When disassembling and assembling the top flattening roller 5, the disassembly fixtures 9 are installed on the top crossbeam 71. When the electric hoist 3 lifts the top flattening roller 5, the hoist 3's lifting strap is located adjacent to and in front of the welding machine track 2. At this time, the discharge arm 7 is in the forward position, the roller disassembly fixture 9 extends forward from the frame 1, and the flattening roller 5 is located directly above the front of the U-shaped groove 93. The electric hoist 3 is lowered, and the flattening roller 5 is placed in the U-shaped groove 93. When installing the flattening roller 5, the flattening roller 5 is placed on the U-shaped groove 93, and the discharge arm 7 is manually controlled to move backward until the discharge arm 7 is in the backward position. Then, the flattening roller 5 moves backward with the discharge arm 7 to the flattening roller seat 8 (the flattening roller seat 8 is manually controlled to be in the low position). The above process is the installation process. The disassembly process is similar, and detailed description is omitted in this embodiment. For the other three flattening rollers 5, there is no need to install auxiliary disassembly fixtures; the electric hoist 3 can be used directly for assisted lifting, and the angled pull meets the usage requirements.

[0042] Among them, see Figure 1-2The roller disassembly fixture 9 in this embodiment includes a longitudinal beam 91, a connecting part 92, and a U-shaped frame. The longitudinal beam 91 is arranged in the front-rear direction, with its rear part located on the upper side of the crossbeam 71. The connecting part 92 is located on the lower rear side of the longitudinal beam 91 and is detachably mounted on the crossbeam 71. It includes a connecting vertical rod, a connecting horizontal rod, a reinforcing rod, and locking bolts. The U-shaped frame is mounted on the upper front side of the longitudinal beam 91 and includes a lower arm, a middle arm, a support plate, and two vertical arms. The two vertical arms are arranged side by side and are both vertical. The lower arm is arranged in the front-rear direction, with its rear part fixed to the upper front side of the longitudinal beam 91. The two vertical arms are respectively fixed to the upper sides of the front and rear ends of the lower arm. The middle arm is arranged in the front-rear direction, with its front and rear ends respectively fixed to the middle of the opposite sides of the vertical arms. The upper side of the middle arm and the upper parts of the two vertical arms form a U-shaped groove 93, and a buffer protective layer 94 is provided on each of them. The support plate is a rectangular plate arranged along the front-to-back direction, with its front and rear edges fixed to two vertical arms, and its top and bottom edges fixed to the middle and lower arms, respectively. The connecting vertical rod is vertically positioned at the front of the crossbeam 71, with its upper end fixed to the lower side of the longitudinal beam 91. The connecting horizontal rod is arranged along the front-to-back direction at the lower side of the crossbeam 71, with its front end fixed to the lower rear side of the connecting vertical rod. The reinforcing rod is arranged diagonally downwards from front to back, with its front end fixed to the lower side of the longitudinal beam 91 and its rear end fixed to the lower front side of the connecting vertical rod. The locking bolt is vertically positioned at the rear of the crossbeam 71, with its upper and lower ends detachably located at the rear ends of the longitudinal beam 91 and the connecting horizontal rod, respectively. Both the rear ends of the longitudinal beam 91 and the rear ends of the connecting horizontal rod have through holes (vertically positioned) for the locking bolts to pass through. The locking bolts pass through the through holes and are locked to the longitudinal beam 91 and the connecting horizontal rod by nuts (which can be located at the lower side of the connecting horizontal rod). The roller removal fixture 9 can be removed by removing the locking bolts. When installing the flattening roller 5, the flattening roller 5 rests against the rear side of the front vertical arm.

[0043] In this embodiment of the present invention, the width of the U-shaped groove 93 is greater than 400mm, the distance between it and the crossbeam 71 in the front-to-back direction is greater than 250mm, and the distance between it and the crossbeam 71 in the vertical direction is 60-100mm.

[0050] Example 5

[0051] Example 5 provides an auxiliary assembly / disassembly fixture for a flattening roller, the structure of which is basically the same as that of Example 1, except that the roller disassembly fixture 9 in this example is made of square tubing and channel steel. The square tubing and channel steel are galvanized square tubing and galvanized channel steel, respectively, with the channel steel having a specification of 50mm×30mm×3mm and the square tubing having a specification of 50mm×50mm×3mm.

[0052] Example 6

[0053] See Figure 1-7Example 6 provides a winding device for an aluminum foil slitting machine. This device includes a frame 1, a welding machine track 2, a welding machine, an electric hoist 3, auxiliary assembly / disassembly fixtures (disclosed in Examples 1-5), and two winding units. The frame 1 is a portal frame structure arranged in a left-right direction. The welding machine track 2 is located at the top front of the frame 1, also arranged in a left-right direction. The welding machine is slidably mounted on the welding machine track 2 and can move left-right; it is used for welding aluminum foil. The welding machine track 2 and the welding machine can also be correspondingly arranged at the bottom of the frame 1. The electric hoist 3 is located above the frame 1, mounted on the workshop ceiling, and can move back-and-forth. It is equipped with a sling for suspending the winding shaft 4 or the flattening roller 5. The two winding units are both located at the front of the frame 1, arranged side-by-side, and are used to wind two layers of double-zero aluminum foil. The winding unit includes a winding shaft 4 and two flattening rollers 5 on its upper and lower sides, both arranged in a left-right direction. The two ends of the winding shaft 4 are respectively mounted on two winding shaft seats 6 (movable up and down, driven by corresponding structures) on both sides of the frame 1. A discharge arm 7 for forward feeding the winding shaft 4 is located on the frame 1 directly below it. The discharge arm 7, mounted on the frame 1, can move back and forth and includes a crossbeam 71 arranged in a left-right direction and two support arms 72 at its front ends. The support arms 72 are arranged in a back-forward direction, located below the rotating shaft of the winding shaft 4, and have grooves at their front ends that mate with the corresponding ends of the rotating shaft of the winding shaft 4. They are slidably mounted on the frame 1. The two ends of the flattening rollers 5 are respectively mounted on two flattening roller seats 8 on both sides of the frame 1. The flattening roller seats 8 can move up and down (driven by corresponding structures). The flattening roller seats 8 and the winding shaft seats 6 can share a vertical slide rail.

[0054] Multiple roll removal fixtures 9 are arranged side-by-side on the front side of the crossbeam 71 of the top discharge arm 7. During slitting, the roll removal fixtures 9 are removed. When installing or removing the top flattening roller 5, the roll removal fixtures 9 are installed on the top crossbeam 71. When the electric hoist 3 lifts the flattening roller 5, the lifting strap is located adjacent to the front of the welding machine track 2; at this time, the discharge arm 7 is in a forward position. The flattening roller 5 is lifted on the lifting strap and is located directly above the front of the U-shaped groove 93; when installing the flattening roller 5, the flattening roller 5 is placed on the U-shaped groove 93, and the discharge arm 7 is in a backward position, then the flattening roller 5 moves backward with the discharge arm 7 to the flattening roller seat 8.

[0055] In this patent, the top flattening roller 5 is disassembled and placed on the discharge arm 7. It does not require two employees to lift it by hand and move it back and forth (it can be pushed in conjunction with the roller). Rolling the flattening roller 5 and moving the discharge arm 7 back and forth allows the flattening roller 5 to be moved horizontally to the hoisting area and hoisted by the electric hoist 3. This reduces the labor intensity of employees and improves the efficiency of cutting and changing rubber rollers.

[0056] 1. The design of this device is simple and ingenious, and it makes reasonable use of the existing discharge arm device of the slitting equipment, thereby reducing safety hazards during operation while saving manpower.

[0057] 2. Originally, changing the roller took about 120 minutes. After using the disassembly and assembly roller changing device, the roller changing time is shortened to 80 minutes. Each roller change can save 40 minutes of production time. A single slitting machine can produce 2000 meters of aluminum foil at a speed of 500m / min.

[0058] Benefit calculation: Theoretical calculation of material coil weight = thickness × width × length of meters × alloy coefficient (based on 2.71), average thickness 0.006mm, average width 1.5m, average price of aluminum foil 6200 yuan / ton.

[0059] The total benefit per unit per use is 0.006 × 1.5 × 2000 × 2.71 × 6.2 = 302.44 yuan.

[0060] According to the roll change record statistics, the slitting machines #4-#9 changed the upper take-up and upper pressure flat roll an average of 21 times per month, with a total monthly benefit of 6351.2 yuan and a total annual benefit of 76214.9 yuan.

[0061] Example 7

[0062] Example 7 provides a winding device for an aluminum foil slitting machine, the structure of which is basically the same as that of Example 6, except that the aluminum foil slitting machine in this example is a slitting machine from Zhuoshen Nonferrous Metals Processing Equipment Co., Ltd., and the overall height is greater than 2.5m.

[0063] Example 8

[0064] Example 8 provides a winding device for an aluminum foil slitting machine, whose structure is basically the same as that of Example 6, except that: in this example, a lifting platform for standing is provided in front of the frame 1, the lifting platform is arranged in the left-right direction and can move up and down. This facilitates the worker's disassembly and assembly of the upper winding shaft 4 and the flattening roller 5. The lifting platform should be able to support two people standing on it, with each person able to hold onto the left and right ends of the winding shaft 4 or the flattening roller 5 respectively. Its height should ensure that the operator can operate the top flattening roller 5, and its low position should be lower than the bottom flattening roller 5.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
