Description

Technical Field

[0001] This invention belongs to the field of conveying and packaging equipment technology, and specifically discloses a conveying device and process for mica boards. Background Technology

[0002] Corrosion-resistant and high-temperature resistant reinforced mica sheets are widely used in harsh environments such as new energy and electrical and chemical industries as high-performance insulation materials. Although these mica sheets have excellent temperature resistance and corrosion resistance, the interlayer bonding strength of the sheet body is limited and the edges and corners are brittle. After the sheets are stacked and formed on the production line, they are prone to edge and corner damage and interlayer peeling damage during transportation and handling, which directly reduces the insulation and protection performance of the mica sheets. Currently, most mica sheet conveying and packaging processes rely on manual installation of foam corner protectors at the four corners of the stack. This manual operation is labor-intensive, and the corner protectors are prone to misalignment and improper fitting, resulting in poor protection consistency and difficulty matching the cycle time of automated continuous conveying production lines. Furthermore, manual installation of corner protectors is prone to scratching the mica sheet surface and carries the risk of corner protectors detaching and failing. It fails to provide stable cushioning protection for the edges and corners of the stack, easily causing unnecessary damage to a large number of qualified corrosion-resistant and high-temperature-resistant reinforced mica sheets during the conveying and transfer process, thus compromising product yield. Therefore, there is an urgent need to develop devices and processes suitable for automated mica sheet conveying to achieve automatic assembly of corner protectors at the stack edges and corners, reducing sheet breakage during conveying and transfer.

The hand-tightening nut is connected to the threaded shaft and pressed against one side of the limiting sleeve for fixation. A protective sheet roller is movably connected inside the two sets of mounting seats and the two sets of limiting sleeves. The paper protective sheet on the outer side of the protective sheet roller passes through the inner side of the upper right-angle frame and the lower right-angle frame.

[0007] In the above technical solution, preferably, a second motor is fixedly installed at one end of the lower right-angle frame, and a second synchronous wheel is fixedly installed on one side of both the rotating shaft of the second motor and the rotating shaft of a set of drive wheels.

Two sets of fixing strips are fixedly installed on the outer side of the upper right-angle frame at the lower side of the disc. Two sets of rolling balls are movably installed on the inner side of the two sets of fixing strips. The rolling balls roll against the lower end of the disc.

[0010] In the above technical solution, preferably, the outer side of the threaded rod is provided with two opposite spiral patterns, each set of push rods is inserted into the corresponding slide rail, and the rotating shaft of the motor is fixedly connected to a set of threaded rods.

[0011] In the above technical solution, preferably, the upper right-angle frame is adapted to the arc-shaped opening, and the distance between the upper right-angle frame, the lower right-angle frame and the right-angle rod is sufficient for the paper protective sheet of the protective sheet roll to pass through.

[0012] In the above technical solution, preferably, the upper side of the spring sheet is fixed to the inner wall of the lower right-angle frame, the two sets of spring sheets clamp the paper protective sheet passing through the inner side of the lower right-angle frame, the two sets of drive wheels press on the paper protective sheet, and the two sets of bevel gears are meshed.

[0013] A mica board conveying process is also provided, for operating a mica board conveying device, comprising the following steps: S1: The motor drives two sets of threaded rods to rotate synchronously, causing the two sets of connecting rods to move closer to each other, pushing the slide rail and the matching plate to rotate along the positioning axis, so that the four sets of right-angle rods are respectively close to the four corners of the goods. S2: Start motor 2 drives the drive wheel to rotate, causing the paper protective sheet of the protective sheet roll to move downward. In conjunction with the hydraulic cylinder, the disc moves upward, so that when the paper protective sheet is rotated and wrapped again by the wrapping machine, it will automatically wrap the paper protective sheet around the corners of the goods. S3: When the wrapping machine wraps the goods, the motor drives the two sets of connecting rods to move away from each other, so that the four sets of right-angle rods unfold away from the goods. With the use of the knife strip, the wrapped paper protective film roll is automatically torn open, which facilitates the next step of packaging and conveying the mica board.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the two sets of conveyors transport the stacked mica sheets, and the winding machine is working, the rotating circular shell drives the short gear, transmission rod and long gear of the connected drive meshing to rotate. The rotating long gear drives the disk and the connected rotation to realize the rotation of the four sets. In conjunction with the winding machine, the corner protection is automatically wrapped during the working process.

[0015] 2. In use, the motor drives a set of threaded rods to rotate. With the connection of two sets of synchronous pulleys and synchronous belts, the two sets of threaded rods rotate synchronously, thereby driving the two sets of connecting rods connected by threads to move closer to each other. The push rods connected to the motor push the slide rail and the matching plate to rotate along the positioning axis, so that the four sets of right-angle rods are close to the four corners of the goods.

[0016] 3. The hydraulic cylinder drives the disc to move downwards, and four sets of right-angle rods are positioned at the corners of the goods. The starting motor drives the connected synchronous pulley two, which, in conjunction with the sleeved synchronous belt two, drives another set of synchronous pulley two and the connected drive wheel to rotate. The rotating drive wheel, through the connected bevel gear, drives another set of bevel gears and the drive wheel to rotate, causing the paper protective sheet of the protective sheet roll to move downwards. In conjunction with the hydraulic cylinder driving the disc to move upwards, the removed paper protective sheet will automatically wrap around the corners of the goods when it is rotated and wrapped again by the wrapping machine, protecting the edges and corners of the goods during the conveying process. The blade is designed to easily tear the paper protective sheet, and two sets of spring clips clamp the paper protective sheet, assisting in positional stability.

[0017] 4. After the subsequent wrapping machine wraps the goods, the motor drives the two sets of connecting rods to move away from each other. When the four sets of right-angle rods unfold and move away from the goods, the paper protective film rolls wrapped around the goods are automatically torn apart in conjunction with the use of the knife strips, which facilitates the packaging and conveying of the mica board in the next step.

[0018] 5. By loosening the hand-tightening nut to secure the limiting sleeve, and opening the limiting sleeve along one side of the mounting base, the protective roller can be quickly replaced. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0023] like Figures 1 to 10The diagram shows a mica sheet conveying device, including a column frame 1. A hydraulic cylinder 3 is fixedly mounted on the upper end of the column frame 1. A disc 4 is movably connected to the lower side of the telescopic rod of the hydraulic cylinder 3. An unfolding mechanism 5 is mounted on the upper side of the disc 4. Four sets of protective sheet assemblies 6 are mounted on the lower side of the unfolding mechanism 5. Positioning shafts 51 are fixedly mounted on both sides of the upper end of the disc 4. Two sets of matching plates 52 are movably mounted on each of the two sets of positioning shafts 51. A slide rail 53 is fixedly mounted on the upper end of each set of matching plates 52 near the positioning shaft 51. A U-shaped frame 54 is fixedly mounted on the other side of the upper end of each set of matching plates 52. An installation component 55 is mounted on the upper side of each set of U-shaped frames 54. An arc-shaped opening 56 is opened on the disc 4 corresponding to the position of each set of protective sheet assemblies 6. Four sets of protective sheet assemblies 6 are fixedly mounted on the upper side of the disc 4. The bearing housing 57 has two sets of threaded rods 58 installed inside. Each set of threaded rods 58 has a connecting rod 59 threaded to both sides. Each connecting rod 59 has a pusher 510 fixedly installed at the lower end of the corresponding slide rail 53. The upper end of the disc 4 has a motor 511 fixedly installed. Each set of threaded rods 58 has a synchronous pulley 512 fixedly installed on one side. The two synchronous pulleys 512 are fitted with a synchronous belt 513. The two matching plates 52 connected on the positioning shaft 51 are mirror symmetrical. The arc-shaped opening 56 is set with the positioning shaft 51 as the center. The outer side of the threaded rods 58 has two opposite spiral patterns. Each pusher 510 is inserted into the corresponding slide rail 53. The rotating shaft of the motor 511 is fixedly connected to a set of threaded rods 58.

[0024] Furthermore, a set of threaded rods 58 connected by motor 511 rotates, coordinating with the connection of two sets of synchronous pulleys 512 and synchronous belt 513, enabling the two sets of threaded rods 58 to rotate synchronously. This drives the two sets of threaded connecting rods 59 to move closer together, and through the connected push rod 510, pushes the slide rail 53 and the matching plate 52 to rotate along the positioning shaft 51, causing the four sets of right-angle rods 62 to approach the corners of the goods. After the subsequent wrapping machine 2 wraps the goods, the two sets of connecting rods 59 are driven away by motor 511, causing the four sets of right-angle rods 62 to unfold away from the goods. With the use of the blade 67, the wrapped paper protective film roll 555 is automatically torn open, facilitating the next step of packaging and conveying the mica board.

[0025] The protective plate assembly 6 includes an upper right-angle frame 61 fixedly mounted at the acute angle of the registration plate 52, a right-angle rod 62 fixedly mounted inside the upper right-angle frame 61, a lower right-angle frame 63 fixedly mounted below the right-angle rod 62, spring pieces 64 fixedly mounted on both inner walls of the lower right-angle frame 63, drive wheels 65 movably connected to the lower side of the lower right-angle frame 63, bevel gears 66 fixedly mounted on the outer sides of the corresponding rotation shafts of the two sets of drive wheels 65, a blade strip 67 fixedly connected to the lower end of the lower right-angle frame 63, a second motor 68 fixedly mounted at one end of the lower right-angle frame 63, and synchronous pulleys 69 fixedly mounted on one side of both the rotation shaft of the second motor 68 and the rotation shaft of the first set of drive wheels 65. A timing belt 610 is fitted on the outer side of the upper right-angle frame 61. Two sets of fixing strips 611 are fixedly installed on the outer side of the upper right-angle frame 61 at the lower side of the disc 4. Two sets of ball bearings 612 are movably installed on the inner side of each of the two sets of fixing strips 611. The ball bearings 612 roll against the lower end of the disc 4. The upper right-angle frame 61 is adapted to the arc-shaped opening 56. The distance between the upper right-angle frame 61, the lower right-angle frame 63 and the right-angle rod 62 is sufficient for the paper protective sheet of the protective sheet roller 555 to pass through. The upper side of the spring piece 64 is fixed to the inner wall of the lower right-angle frame 63. The two sets of spring pieces 64 clamp the paper protective sheet passing through the inner side of the lower right-angle frame 63. Two sets of drive wheels 65 press on the paper protective sheet. The two sets of bevel gears 66 are meshed.

[0026] Furthermore, the hydraulic cylinder 3 drives the disc 4 to move downwards, and the four sets of right-angle rods 62 are respectively located at the corners of the goods. The starting motor 68 drives the connected synchronous pulley 69, which, together with the sleeved synchronous belt 610, drives another set of synchronous pulleys 69 and the connected drive wheel 65 to rotate. The rotating drive wheel 65 drives another set of bevel gears 66 and drive wheel 65 to rotate through the connected bevel gear 66, causing the paper protective sheet of the protective sheet roll 555 to move downwards. In conjunction with the hydraulic cylinder 3, the disc 4 moves upwards, so that when the removed paper protective sheet is rotated and wrapped again by the wrapping machine 2, it will automatically wrap the paper protective sheet at the corners of the goods, protecting the edges and corners of the goods during the conveying process. The blade 67 is set to facilitate tearing the paper protective sheet, and the two sets of spring clips 64 clamp the paper protective sheet to help stabilize its position.

[0027] The mounting assembly 55 includes two sets of mounting seats 551 fixedly mounted on the upper end of each set of U-shaped frames 54. The upper side of the mounting seat 551 is movably connected to the limit sleeve 552. A threaded shaft 553 is fixedly mounted on one side of the upper end of the mounting seat 551. A notch is provided on one side of the limit sleeve 552 corresponding to the position of the threaded shaft 553. A hand-tightening nut 554 is threadedly connected to the outside of the threaded shaft 553. The hand-tightening nut 554 is connected to the threaded shaft 553 and pressed against one side of the limit sleeve 552 for fixation. The two sets of mounting seats 551 and the two sets of limit sleeves 552 are movably connected to the inside of the protective sheet roller 555. The paper protective sheet on the outside of the protective sheet roller 555 passes through the inside of the upper right-angle frame 61 and the lower right-angle frame 63.

[0028] Furthermore, by loosening the hand-tightening nut 554 to fix the limiting sleeve 552, and opening the limiting sleeve 552 along one side of the mounting base 551, the protective film roller 555 can be quickly replaced.

[0029] A winding machine 2 is fixedly installed on the lower side of the column frame 1. A gear ring 7 is fixedly installed on the upper side of the outer shell of the disk 4 and the outer shell of the winding machine 2. A transmission rod 8 is movably installed on the inner side of the column frame 1. A long gear 9 is fixedly installed on the upper side of the transmission rod 8. The long gear 9 meshes with the gear ring 7 on the disk 4. A short gear 10 is fixedly installed on the lower side of the transmission rod 8. The short gear 10 meshes with the gear ring 7 on the outer shell of the winding machine 2. Conveyors 11 are installed on both sides of the winding machine 2.

[0030] Furthermore, the two groups use conveyor 11 to transport the stacked mica sheets. When the winding machine 2 is working, the rotating circular shell drives the short gear 10, transmission rod 8, and long gear 9 connected to the 7 to rotate. The rotating long gear 9 drives the disc 4 and the connected 7 to rotate, so as to rotate the four groups 6. In conjunction with the winding machine 2, the corner protection is automatically wrapped during the working process.

[0031] A mica board conveying process is also provided, for operating a mica board conveying device, comprising the following steps: S1: The motor 511 drives the two sets of threaded rods 58 to rotate synchronously, so that the two sets of connecting rods 59 move closer to each other, pushing the slide rail 53 and the matching plate 52 to rotate along the positioning shaft 51, so that the four sets of right-angle rods 62 are close to the four corners of the goods respectively. S2: Start motor 68 drives drive wheel 65 to rotate, causing the paper protective sheet of protective sheet roll 555 to move downward. In conjunction with hydraulic cylinder 3, drive disc 4 to move upward. When the paper protective sheet is rotated and wrapped again by wrapping machine 2, it will automatically wrap the paper protective sheet around the corners of the goods. S3: When the wrapping machine 2 wraps the goods, the motor 511 drives the two sets of connecting rods 59 to move away from each other, so that the four sets of right-angle rods 62 are spread away from the goods. With the use of the knife strip 67, the wrapped paper protective film roll 555 is automatically torn open, which facilitates the next step of packaging and conveying the mica board.

[0032] Working principle: First, the two sets of conveyors 11 transport the stacked mica sheets. When the winding machine 2 is working, the rotating circular shell drives the short gear 10, transmission rod 8, and long gear 9 connected to the 7 to rotate. The rotating long gear 9 drives the disc 4 and the connected 7 to rotate, so as to rotate the four sets of 6. In the process of working, the winding machine 2 automatically performs protective winding of the corners.

[0033] In use, a set of threaded rods 58 connected by a motor 511 are driven to rotate. With the connection of two sets of synchronous pulleys 512 and synchronous belts 513, the two sets of threaded rods 58 rotate synchronously, thereby driving the two sets of threaded connecting rods 59 to move closer to each other. Through the connected push rod 510, the slide rail 53 and the matching plate 52 are pushed to rotate along the positioning shaft 51, so that the four sets of right-angle rods 62 are respectively close to the four corners of the goods.

[0034] Secondly, the hydraulic cylinder 3 drives the disc 4 to move downwards, and the four sets of right-angle rods 62 are respectively at the corners of the goods. The starting motor 68 drives the connected synchronous pulley 69, which, together with the sleeved synchronous belt 610, drives another set of synchronous pulleys 69 and the connected drive wheel 65 to rotate. The rotating drive wheel 65 drives another set of bevel gears 66 and drive wheel 65 to rotate through the connected bevel gear 66, which drives the paper protective sheet of the protective sheet roll 555 to move downwards. In conjunction with the hydraulic cylinder 3 driving the disc 4 to move upwards, the paper protective sheet that has been removed will automatically wrap around the corners of the goods when it is rotated and wrapped again by the wrapping machine 2, protecting the corners of the goods during the conveying process. The blade 67 is set to facilitate tearing the paper protective sheet, and the two sets of spring clips 64 clamp the paper protective sheet to help stabilize its position.

[0035] After the subsequent wrapping machine 2 wraps the goods, the motor 511 drives the two sets of connecting rods 59 to move away from each other, so that the four sets of right-angle rods 62 are spread away from the goods. With the use of the blade 67, the wrapped paper protective film roll 555 is automatically torn open, which facilitates the next step of packaging and conveying the mica board.

[0036] By loosening the hand-tightening nut 554 to fix the limiting sleeve 552, and opening the limiting sleeve 552 along one side of the mounting base 551, the protective film roller 555 can be quickly replaced.

[0037] In this invention, the electrical equipment of the column frame 1, winding machine 2, hydraulic cylinder 3, motor 511, motor 68, and conveyor 11 are used in conjunction with related sensors and components. The connection and usage methods are common knowledge in the field, and the working principle is a well-known technology.
