Description

Technical Field

[0001] The present invention relates to the field of material roll unwinding and taping devices, and in particular to a taping device designed with an improved design for the current process of first scraping pressure-sensitive adhesive and then covering with release paper. Background Art

[0002] In order to meet the needs of environmental protection and cost reduction, the current paper products such as sealing tape have changed the traditional double-sided adhesive process to a process of first applying pressure-sensitive hot glue and then covering it with release paper. Because double-sided adhesives with good adhesion, such as 3M adhesive, are priced by meter, while pressure-sensitive adhesives are priced by kilogram; release paper is only used to cover the isolation pressure-sensitive adhesive, so the lowest cost and thinnest can be used to meet market demand. Through process improvements, the overall cost can be reduced by at least half. The traditional process of scraping release paper is to first scrape the product with glue using a scraper. After the scraper has completed its stroke, the release paper can be applied to the head and finally cut. The cutting process is often the last step, which is easy to lift thin and soft products, forming wrinkles, making the quality difficult to guarantee or even impossible to apply.

[0003] To address this issue, a clever production process involves pre-coating pressure-sensitive adhesive onto release paper, then applying existing double-sided tape to the product. This process is then cut off on the large tape tray. This prevents the product from wrinkling during the adhesive application and cutting process, effectively shortening application time and improving efficiency. This not only addresses the current high-speed response issues of conventional adhesive heads, but also addresses the wrinkling issue associated with the final cutting process for thin and soft paper products. However, there is no production equipment available to meet existing production needs for this improved production process.

[0027] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0028] See also Figures 1 to 9As shown, the tape applying device 100 of the present invention includes a frame 1, a first guide wheel assembly 2, a feed drive adjustment group 3, a glue coating device 4, a rotary disk mechanism 5, a cutting assembly 6 and a discharge assembly 7. The first guide wheel assembly 2, the feed drive adjustment group 3, the glue coating device 4, the rotary disk mechanism 5, the cutting assembly 6 and the discharge assembly 7 are installed on the frame 1. The feed drive adjustment group 3, the glue coating device 4, the rotary disk mechanism 5 and the cutting assembly 6 are arranged at intervals along the left and right directions of the frame 1. The first guide wheel assembly 2 includes a plurality of first guide wheels 21. The first guide wheels 21 are located at the input end of the feed drive adjustment group 3, the output end of the feed drive adjustment group 3 and below the glue coating device 4. The first guide wheels 21 located at the input end of the feed drive adjustment group 3 are staggered along the height direction of the frame 1. The upper and lower sides of the first guide wheel 21 located at the input end of the feed drive adjustment group 3 are provided with an upper baffle 22 and a lower baffle 23 with adjustable angles. The first guide wheel 21 located at the output end of the feed drive adjustment group 3 and below the glue coating device 4 is obliquely arranged along the upper right direction of the frame 1. The feed drive adjustment group 3 is used to wind the material strip 200 and drive the material strip 200 to be transported to the glue coating device 4. In other words, the feed drive adjustment group 3 can provide power for the transportation of the material strip 200. The material strip 200 guided by the first guide wheel 21 enters the feed drive adjustment group 3 and is output into the glue coating device 4. The glue coating device 4 is used to apply a glue layer on the material strip 200 and can apply a glue layer on the material strip 200. The rotary disc mechanism 5 is rotatably mounted on the frame 1. The cutting assembly 6 is used to cut the material strip 200 wound on the rotary disc mechanism 5. The discharging assembly 7 is used to output the material strip 200 that has been coated with the glue layer and cut and adhere it to the workpiece. The discharging assembly 7 is a pressing roller. By pressing, the material strip 200 attached to the workpiece is pressed against the workpiece, and the pressing roller flattens the product after taping. That is, after the material strip 200 is coated with the adhesive layer, it is directly cut according to the required length and then attached to the workpiece, without the traditional problem of wrinkling of the product caused by directly coating the adhesive layer on the workpiece and then cutting. In this embodiment, the material strip 200 is release paper, and when the adhesive layer is pressure-sensitive adhesive, the pressure-sensitive adhesive is cleverly pre-coated on the release paper. The release paper with pressure-sensitive adhesive is equivalent to the structure of double-sided tape, and then cut according to the needs of the workpiece. The "double-sided tape" produced is then attached to the product, and the cutting is performed in advance on the rotary disc mechanism 5 for attaching. This effectively shortens the attaching time and improves product efficiency. It not only solves the problem that the current conventional attaching head cannot respond at high speed, but also solves the wrinkling problem of the finishing cutting process of thin and soft paper products, with the advantages of high work efficiency and low cost. As follows:

The full load sensor 84 is electrically connected to the stopping device 92 of the material tray placement device 9. The operation of the material belt turntable 91 is controlled by the signal fed back by the full load sensor 84. When encountering some emergency situations, such as when the material belt 200 is fully loaded, the full load sensor 84 can feed back the signal to the stopping device 92. The stopping device 92 can stop the rotation of the material belt 200 by pressing. Preferably, the stopping device 92 can be a purely mechanical structure, or it can be an electromagnetic brake or a magnetic powder brake.

The rotation of the feed main shaft 31 drives the rotation of the driven shafts 32. The feed main shaft 31 is provided with a blowing structure 33, which prevents the material tape 200 from adhering to the feed main shaft 31.

[0033] See also Figure 3 As shown, the glue coating device 4 includes a hot glue scraper 41 and a tape break detection sensor 42. The hot glue scraper 41 is capable of spraying the glue layer and is mounted on the frame 1. The tape break detection sensor 42 is located on one side of the hot glue scraper 41. The tape break detection sensor 42 is used to detect tape breaks in the material strip 200 and is electrically connected to the hot glue scraper 41. The purpose of the tape break detection sensor 42 is to detect if the tape breaks and stop the hot glue scraper 41 from applying glue, thereby preventing glue from spilling. After the laminating length is accurately calculated, the cutter 62 pre-cuts the material strip 200 on the rotary disk mechanism 5.

[0034] See also Figures 1 to 3 As shown, the cutting assembly 6 includes a cutter rotation drive 61, a cutter 62, and a wiping roller 63 for cleaning the cutter 62. The cutter rotation drive 61 is mounted on the frame 1, and the cutter 62 is mounted at the output end of the cutter rotation drive 61. Driven by the cutter rotation drive 61, the cutter 62 rotates to cut the material strip 200. The wiping roller 63 is located on one side of the cutter 62 and wipes glue off the cutter 62. The wiping roller 63 cleans any residual glue from the cutter 62. The wiping roller 63 is kept soaked in lubricating oil. To prevent oil from splashing onto the product, an oil tank 64 is provided below the wiping roller 63 to receive dripping lubricating oil.

[0035] See also Figures 1 to 9As shown, the rotary disc mechanism 5 includes a rotary drive device 51 and a rotary disc 52. The rotary drive device 51 is installed on the frame 1. The rotary disc 52 rotates under the drive of the rotary drive device 51. The frame 1 is equipped with an air intake port 53 and an air blowing port 54. The air intake port 53 is provided with a negative pressure suction device. The air intake port 53 faces the middle conveying part of the rotary disc 52. The air suction from the air intake port 53 makes the material strip 200 adhere to the rotary disc 52 for conveying. The air blowing device is provided at the air blowing port 54. The air blowing from the air blowing port 54 faces the output end of the rotary disc 52. The air blowing from the air blowing port 54 separates the material strip 200 from the rotary disc 52 at the output end of the rotary disc 52. Specifically, the rotary disc 52 includes a rotary conveying sealing disc 521 and a rotating main disc 522. The rotating main disc 522 is close to the rotary conveying sealing disc 521 by screws 523 and springs 524. The unique feature of this device is that the rotary sealing disc 521 and the rotating main disc 522 have a clearance fit of approximately 0.02mm, which provides a good sealing effect and prevents wear on the rotating main disc 522, thus resolving the problem of easy wear of the rotating main disc 522. The rotary sealing disc 521 is provided with through holes, which mainly serve as the air intake 53 and air outlet.

[0036] The method of using the taping device 100 of the present invention is as follows:

Figure 3 In the direction indicated by the arrow A, the material strip 200 enters the second guide wheel 83 in sequence, and the rotation of the driving wheel 811 drives all the second guide wheels 83 to rotate, and enters the winding partition 82 under the guidance of the second guide wheel 83. The material strip 200 leaving the winding partition 82 enters the feeding main shaft 31 and the driven shaft 32 of the feeding drive adjustment group 3 under the guidance of the first guide wheel 21, and the rotation of the feeding main shaft 31 drives the driven shaft 32 to rotate, so that the material strip 200 is conveyed to the glue coating device 4, and the broken belt detection sensor 42 detects the broken belt of the material strip 200. If there is a broken belt phenomenon, the hot glue scraper 41 will no longer scrape the glue. If there is no broken belt phenomenon, the hot glue scraper 41 will not scrape the material strip 2 00 is scraped for glue, at this time the material strip 200 has a glue layer on the outside, and the cutter 62 is driven by the cutter rotation drive device 61 to rotate to cut the material strip 200 by rotation, because the conveying part on the turntable 52 of the rotary disk mechanism 5 has an air suction port 53, under the action of the adsorption force of the air suction port 53, the material strip 200 is close to the turntable 52, and when the material strip 200 on the turntable 52 rotates to the air blowing port 54, under the action of the air blowing port 54, the material strip 200 falls to the bottom of the turntable 52 and adheres to the workpiece on the conveyor belt below, that is, the product that needs to be bonded, and when the workpiece continues to be conveyed forward, the pressing roller presses the material strip 200 onto the workpiece through pressing, and the bonding is completed at this time.
