Description

Technical Field

[0001] This invention relates to the field of canvas processing technology, and in particular to a winding method and winding device for canvas production. Background Technology

[0002] Canvas generally comes in two types: one is made by impregnating fabric with adhesive, and the other is made by bonding an adhesive layer to one side of the fabric. The equipment for producing this type of canvas includes an adhesive layer output device and a fabric winding device. During canvas production, fabric rollers are mounted on the winding device. The fabric on the rollers passes through guide rollers and bonds with the adhesive layer output from the adhesive layer output device. Then, the fabric is rewound back onto the winding device.

[0003] Patent CN110697478A discloses a fabric rolling device and method for producing rubberized canvas, belonging to the field of rubberized canvas production technology. The device includes a horizontally arranged fabric roller and a take-up roller; a main support for mounting the take-up roller and a secondary support for mounting the fabric roller, the secondary support being movably connected to the main support; a driving device for driving the secondary support to move left and right relative to the main support; and a detection device for detecting fabric misalignment, the detection device being disposed on one side of the fabric between the fabric roller and the take-up roller. During production, the detection device detects misaligned fabric, and then the position of the fabric roller is changed by controlling the movement of the secondary support, thereby achieving real-time correction of fabric misalignment. The produced rubberized canvas has a neat edge adhesive layer, eliminating the need for edge trimming during use, reducing material costs, and improving production efficiency.

[0004] However, the device can cause the canvas to become uneven during the rolling process, and if left for too long, it can cause wrinkles, affecting the subsequent use of the canvas. Summary of the Invention

[0005] The purpose of this invention is to provide a winding method and winding device for canvas production, so as to solve the problem that the canvas is easily uneven during the winding process, and the canvas is easily wrinkled after being left for too long, which affects the subsequent use of the canvas.

[0006] A method for winding canvas during production:

[0007] S1: First, the canvas is guided and conveyed by the guide conveyor device. When the guide conveyor device is working, the drive motor 2 on the mounting plate drives one set of drive gears to rotate. The drive gear drives another set of drive gears that mesh with it to rotate relative to each other. When the two sets of drive gears rotate relative to each other, they drive two guide rollers to rotate relative to each other. The two guide rollers guide and convey the canvas to the conveying assembly.

[0008] S2: When the guide conveyor transports the canvas to the winding device, the distance between the two winding components can be adjusted by adjusting the settings of the adjustment components so that both sides of the canvas can be placed on the two winding components. When the adjustment components are working, the adjustment motor drives the bidirectional screw to rotate on the two mounting seats. The rotation of the bidirectional screw drives the two sets of adjustment tables to perform adjustment operations in the same or opposite directions. The two sets of adjustment tables drive the winding components to move closer or further away.

[0009] S3: After the adjustment components are adjusted, place the end of the canvas on the take-up roller. At this time, the end of the canvas is fixed by the fixing components. Then, the fixing push rod drives the connecting plate to adjust on the fixing adjustment groove. Then, the connecting plate drives the fixing plate to move. The fixing plate and the fixing groove correspond to each other to press the canvas. After the end of the canvas is fixed, the take-up components on both sides perform the take-up operation. At this time, the take-up motor on the take-up mounting base drives the rotating plate to rotate. When the rotating plate rotates, it drives the take-up roller to perform the take-up operation.

[0010] S4: After the canvas is rolled up, the fixing component is released, and the adjusting component moves to both sides to drop the canvas. At this time, the pushing component moves the storage box to the bottom of the rolling component. After the storage box holds the dropped canvas, the pushing component resets to start the next roll of canvas rolling operation.

[0011] A canvas production winding device includes a mounting base, a guiding conveyor, a winding device, and a storage device. The guiding conveyor, winding device, and storage device are sequentially arranged on the mounting base in winding order. The winding device consists of an adjusting component, two sets of winding components, and two sets of fixing components. The adjusting component is fixedly mounted on the mounting base. The two sets of winding components are respectively mounted on both sides of the adjusting component. The two sets of fixing components are respectively mounted on the two sets of winding components. The storage device consists of two sets of pushing components and a storage box. The two sets of pushing components are symmetrically arranged on both sides of the mounting base. The storage box is located on the working ends of the two sets of pushing components, and the storage box is correspondingly arranged with the two sets of winding components.

[0012] Furthermore, the guiding and conveying device includes a guide frame, a mounting cover, a drive motor, two sets of guide rollers, and two sets of drive gears. The guide frame is fixedly mounted on one side of the mounting base. The two sets of guide rollers are vertically arranged side by side and rotate on the guide frame, with one end of each set of guide rollers extending outside the guide frame. The two sets of drive gears are respectively fixedly mounted on the ends of the two sets of guide rollers located outside the guide frame, and the two sets of drive gears mesh with each other. The mounting cover covers the outside of the two sets of drive gears, and the drive motor is fixedly mounted on the mounting cover. The output end of the drive motor is fixedly connected to one of the sets of drive gears.

[0013] Furthermore, the adjustment assembly includes an adjustment motor, a bidirectional lead screw, two mounting bases, two sliding rods, and two sets of adjustment platforms. The two mounting bases are fixedly arranged on both sides of the mounting base at a distance. The two ends of the bidirectional lead screw are rotatably arranged in the middle position of the two mounting bases. The two ends of the two sliding rods are respectively arranged on the two mounting bases, and the two sliding rods are respectively located on both sides of the bidirectional lead screw. The two sets of adjustment platforms are respectively screwed to both sides of the bidirectional lead screw and slidably arranged on the two sliding rods.

[0014] Furthermore, each winding assembly includes a winding mounting base, a winding motor, a rotating plate, and a winding roller. The winding mounting base is vertically fixed on the adjustment platform, the winding motor is fixed on one side of the winding mounting base, the rotating plate is fixed on the output shaft of the winding motor, and one end of the winding roller is fixed on the rotating plate.

[0015] Furthermore, the rotating plate is provided with a fixing adjustment groove, the winding roller is provided with a fixing groove, and the fixing component is provided on the fixing adjustment groove of the rotating plate, with the fixing part of the fixing component corresponding to the fixing groove on the winding roller.

[0016] Furthermore, the fixing assembly includes a fixing push rod, a connecting plate, and a fixing plate. The output end of the fixing push rod is positioned downwards and extends into the fixing adjustment groove. One end of the connecting plate is connected to the output end of the fixing push rod, and the other end of the connecting plate is connected to the fixing plate. The fixing plate is located above the fixing groove, and the shape and size of the fixing plate correspond to the fixing groove.

[0017] Furthermore, each set of the pushing components comprises an electric push rod, a pushing slide rail, a pushing slide table, and a connecting block. The pushing slide rail is mounted on the mounting base, the electric push rod is mounted beside the pushing slide rail, the pushing slide table is slidably mounted on the pushing slide rail, one end of the connecting block is connected to the output end of the electric push rod, and the other end of the electric push rod is connected to the pushing slide table.

[0018] Furthermore, a receiving guide plate is installed at an angle on one side of the storage box, and the receiving guide plate is arranged corresponding to the winding roller.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] When the canvas needs to be rolled up, the canvas is first guided and conveyed by a guide conveyor to prevent wrinkles and positional shifts during transport to the winding device. When the guide conveyor delivers the canvas to the winding device, the distance between the two winding components is adjusted by an adjusting component so that both sides of the canvas can be placed on them. After both sides of the canvas are placed, a fixing component secures them to prevent loosening during winding. Once secured, the winding components roll up the canvas. After winding, the fixing component releases, and the adjusting component moves to the sides to drop the canvas. At this point, a pushing component moves a storage box under the winding components, collecting the dropped canvas. The pushing component then resets to begin the next roll of canvas winding. This application achieves automatic canvas winding through the coordinated operation of various components, improving winding efficiency and canvas flatness, making it highly practical.

[0034] A method for winding canvas during production:

[0035] S1: First, the canvas is guided and conveyed by the guide conveyor device 2. When the guide conveyor device 2 is working, the drive motor 23 on the mounting cover plate 22 drives one set of drive gears 25 to rotate. The drive gear 25 drives another set of drive gears 25 meshing with it to rotate relative to each other. When the two sets of drive gears 25 rotate relative to each other, they drive the two guide rollers 24 to rotate relative to each other. The two guide rollers 24 guide and convey the canvas to the conveying assembly.

[0036] S2: When the guide conveyor 2 conveys the canvas to the winding device 3, the distance between the two winding components 32 can be adjusted by adjusting the component 31 so that both sides of the canvas can be placed on the two winding components 32. When the adjusting component 31 is working, the adjusting motor 311 drives the bidirectional screw 312 to rotate on the two mounting seats 313. The rotation of the bidirectional screw 312 drives the two sets of adjusting tables 315 to perform adjustment operations in the same or opposite directions. The two sets of adjusting tables 315 drive the winding components 32 to move closer or further away.

[0037] S3: After the adjustment component 31 is adjusted, place the end of the canvas on the take-up roller 324. At this time, the end of the canvas is fixed by the fixing component 33. The fixing push rod 331 drives the connecting plate 332 to adjust on the fixing adjustment groove 325. Then the connecting plate 332 drives the fixing plate 333 to move. The fixing plate 333 and the fixing groove 326 are aligned to press the canvas. After the end of the canvas is fixed, the take-up components 32 on both sides perform the take-up operation. At this time, the take-up motor 322 on the take-up mounting base 321 drives the rotating plate 323 to rotate. When the rotating plate 323 rotates, it drives the take-up roller 324 to perform the take-up operation.

[0038] S4: After the canvas is finished rolling, the fixing component 33 is released, and the adjusting component 31 moves to both sides to drop the canvas. At this time, the pushing component 41 drives the storage box 42 to move below the rolling component 32. After the storage box 42 holds the dropped canvas, the pushing component 41 resets to start the next roll of canvas rolling operation.

[0039] The following is combined with Figures 1 to 6As shown, this embodiment of the invention provides a canvas production winding device 3, including a mounting base 1, a guiding conveyor 2, a winding device 3, and a storage device 4. The guiding conveyor 2, the winding device 3, and the storage device 4 are sequentially arranged on the mounting base 1 in winding order. The winding device 3 consists of an adjusting component 31, two sets of winding components 32, and two sets of fixing components 33.

The two sets of pushing components 41 are symmetrically arranged on both sides of the mounting base 1, and the storage box 42 is arranged on the working ends of the two sets of pushing components 41. The storage box 42 is correspondingly arranged with the two sets of winding components 32. When canvas winding is required, the guiding conveyor 2 is first set up... The process of guiding and conveying the canvas ensures that it does not wrinkle or shift position during transport to the winding device 3. When the guiding and conveying device 2 delivers the canvas to the winding device 3, the distance between the two winding components 32 is first adjusted by the setting of the adjusting component 31 so that both sides of the canvas can be placed on the two winding components 32. After both sides of the canvas are placed, the fixing component 33 fixes the two sides of the canvas to prevent it from loosening during winding. After the canvas is fixed, the winding component 32 works to wind up the canvas. After the canvas is wound up, the fixing component 33 is released, and the adjusting component 31 moves to both sides to drop the canvas. At this time, the pushing component 41 works to move the storage box 42 to below the winding component 32. The storage box 42 collects the dropped canvas, and the pushing component 41 resets to start the next roll of canvas winding operation. This application completes the automatic winding operation of canvas through the coordinated work of various components, which improves the winding efficiency and the flatness of the canvas, and has high practicality.

The drive gear 25 drives the other set of drive gears 25 that meshes with it to rotate relative to each other.
