Description

Technical Field

[0001] The invention relates to the technical field of transparent adhesive tape production, in particular to transparent adhesive tape production equipment and a production process thereof. Background Art

[0002] Transparent tape is made on the basis of BOPP original film, which is subjected to high-voltage corona to make one side rough, then coated with glue, and then divided into small rolls through strips. This is the tape we use in daily life. The purpose of transparent tape is to connect two separate materials together. The production process of traditional transparent tape is: unwinding - spraying glue - drying - slitting - winding.

[0003] In the traditional scotch tape production system, the machines used for gluing, drying and cutting are mostly separate. Gluing is to put the film on the coating machine to add coating glue, drying is to use a practical heating device to dry the surface of the tape, and cutting is to use a slitting machine to cut into the required width of the tape for daily use. The flow of semi-finished products between each process needs to be completed manually, and its production efficiency is low. Therefore, many scotch tape production and processing systems with both gluing and cutting functions have been created. However, the following problems still exist in the traditional scotch tape production process:

[0004] 1. In the process of conveying the tape, the tape is usually conveyed along the length direction of the tape. Since the thickness of the tape is relatively thin, wrinkles are easily formed on the surface of the tape during the conveying process. The existence of wrinkles is not only not conducive to the uniform spraying of the glue on the surface of the tape, but also has an adverse effect on the subsequent winding operation; 2. In the process of gluing, most of the transparent tape production and processing systems use the method of workers directly pouring glue into the machine and applying the glue on the tape through the coating pipe. This method of gluing easily makes the glue cover the surface of the film unevenly, resulting in different glue thicknesses on the surface of the tape, and even glue bulges on some surfaces, thereby affecting the quality of the finished tape;

[0005] 3. In the process of cutting, most traditional tape production equipment cannot make corresponding adjustments to the cutting knife according to actual needs. For example, the inclination angle of the cutting knife cannot be adjusted in time, or the distance between the cutting knives cannot be adjusted adaptively in time, so that the system can only produce and process small rolls of tape of one specification. The traditional method of adjusting the distance between the knives mostly requires the cutting knife to be disassembled, adjusted and then installed, and this operation is usually manual, which is complicated and not very practical. At the same time, the glue adhered to the cutting knife during the cutting process cannot be removed in time, and the long-term accumulation of glue on the knife is easy to affect the slitting effect.

[0006] Therefore, in view of this, a transparent tape production device and a production process thereof are provided to provide a solution to the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See also Figure 1 - Fig.15The present invention provides a technical solution: a transparent adhesive tape production device and a production process thereof, comprising a support frame 101, wherein the inner sides of both ends of the support frame 101 are rotatably connected with a reel 102 and a reel 103, wherein the inner side of the support frame 101 is located between the reel 102 and the reel 103 and is rotatably connected with a plurality of first conveying rollers 105 and a second conveying roller 106, wherein when the adhesive tape is used, the reel 103 reels the adhesive tape after the reel 103 unwinds the adhesive tape through the reel 102 and passes through the plurality of first conveying rollers 105 and the second conveying rollers 106, wherein a reeling drive motor 104 is installed on the support frame 101, and the output end of the reeling drive motor 104 is connected with the reel 103;

[0060] The support frame 101 is provided with the following components in sequence along the direction from the unwinding roller 102 to the winding roller 103:

[0061] The glue coating mechanism 200 is used to coat the glue on the surface of the tape;

[0062] A drying mechanism 300 is used to dry the glue on the surface of the tape;

[0063] A cutting mechanism 400, used for cutting the tape;

[0064] The tool cleaning mechanism 500 is used to clean the slitting tool.

[0065] See also Figure 1 - Figure 3 At least one flattening roller 107 is rotatably connected to the bottom of one end of the unwinding roller 102 on the inner side of the support frame 101. The outer circumference of the flattening roller 107 is provided with a plurality of guide lines that gradually spread to both ends. Specifically, when the adhesive tape is passing around the flattening roller 107, due to the existence of the guide lines, the flattening roller 107 can guide and transport the adhesive tape in the width direction while transporting the adhesive tape in the length direction. When there are wrinkles on the adhesive tape, the wrinkles will gradually spread to both sides along the guide lines until they disappear, thereby eliminating the wrinkles on the adhesive tape. Please refer to Figure 3 - Figure 6The glue coating mechanism 200 includes a first mounting frame 201 fixed on the top of the support frame 101, a glue tank 202 is provided on the top of the first mounting frame 201, a material discharge box 204 is fixedly connected to the bottom of the first mounting frame 201 and below the glue tank 202, the bottom output end of the glue tank 202 passes through the first mounting frame 201 and extends into the inner side of the material discharge box 204, a switch valve 203 is provided on the bottom output end of the glue tank 202, a bidirectional conveying roller 205 is rotatably connected to the inner side of the material discharge box 204, a plurality of conveying sheets diffused to both ends are provided on the outer periphery of the bidirectional conveying roller 205, a plurality of material discharge holes 206 are provided at the bottom of the material discharge box 204 and below the bidirectional conveying roller 205, one end of the bidirectional conveying roller 205 extends out of the material discharge box 204 and is fixed with a first pulley 207, a A first drive motor 208 is provided, and a second pulley 209 is fixed to the output end of the first drive motor 208. The second pulley 209 is connected to the outer side of the first pulley 207 with a first transmission belt 210. Specifically, the adhesive tape below the glue tank 202 is arranged to be straight, so that the glue can be coated on the surface of the adhesive tape. When coating, a proper amount of glue is first stored in the inner side of the glue tank 202. When the glue needs to be coated, the switch valve 203 is started to open the valve, and the glue in the glue tank 202 flows into the inner side of the discharge box 204. At the same time, the first drive motor 208 is started to drive the second pulley 209 to rotate, and the bidirectional conveying roller 205 is driven to rotate through the first transmission belt 210 and the first pulley 207. The glue is transported to both sides through the conveying sheet diffused from the outer circumference of the bidirectional conveying roller 205 to both ends, and drips onto the upper surface of the adhesive tape through the discharge hole 206.

[0066] See also Figure 3 - Figure 6A second mounting bracket 211 is fixed to the middle of one end of the unloading box 204 away from the unwinding roller 102, and a second driving motor 212 is installed on one end of the second mounting bracket 211 away from the unloading box 204. A first threaded rod 213 is fixedly connected to the output end of the second driving motor 212, and the first threaded rod 213 is rotatably connected to the inner side of the second mounting bracket 211, and a displacement connecting block 214 is threadedly connected to the outer side of the first threaded rod 213. The displacement connecting block 214 is slidably connected to the second mounting bracket 211, and both sides of the bottom of the displacement connecting block 214 are rotatably connected to an inclined scraper plate 215, and the scraper plate 215 is arranged above the adhesive tape, and one end of the scraper plate 215 away from the displacement connecting block 214 is rotatably connected to a first guide rod 216, and the first guide rod 216 is connected to the support The support frame 101 is slidably connected, and a waste box 217 is provided on the inner side of the support frame 101 and below the scraper plate 215. Specifically, when in use, a small glue coating gap is left between the scraper plate 215 and the surface of the tape, and the height of the glue coating gap is the thickness of the glue on the surface of the tape. When the glue drips onto the tape and is transported to one end of the scraper plate 215, the glue above the glue coating gap will be blocked by the scraper plate 215 and gradually move outward along the end surface of the scraper plate 215 until it leaves the surface of the tape and falls into the waste box 217 for collection. The setting of the scraper plate 215 can gradually spread the glue from the middle to the outside, so that the glue is evenly coated on the surface of the tape, and the thickness of the glue on the surface of the tape is the same, thereby effectively avoiding the situation where the glue bulges on the surface of the tape.

[0067] It should be noted that, in the present embodiment, the inclination angle of the scraper plate 215 can be adjusted, thereby adjusting the speed of spreading the glue. The specific adjustment method is that the second drive motor 212 can drive the first threaded rod 213 to rotate when it is started. When the first threaded rod 213 rotates, the displacement connecting block 214 will slide on the inside of the second mounting frame 211, thereby driving the connection between the two scrapers 215 to move. Since the first guide rod 216 slides on the inside of the support frame 101, the inclination angle is changed, thereby controlling the inclination angle of the scraper plate 215 to meet the needs of different gluing speeds.

[0068] See also Figure 7The drying mechanism 300 includes a plurality of heat-conducting covers 303 arranged on the inner side of the support frame 101 and located at the end of the glue coating mechanism 200 away from the unwinding roller 102. The top and bottom of the heat-conducting covers 303 are fixed with connecting strips 302. The outer side of the connecting strips 302 is slidably connected with a guide strip 301.

A pull-out plate 305 is installed on one side of the heating tube 304. The pull-out plate 305 is detachably connected to the heat-conducting cover 303. The second conveying rollers 1 located on both sides of the heat-conducting cover 303 06 are staggered up and down, and the tape passes through the two sides of the heat-conducting cover 303 in a curved reciprocating shape when it passes through the plurality of second conveying rollers 106 staggered up and down. Specifically, the heat-conducting cover 303 can be pulled out and installed on the inner side of the support frame 101 through the arrangement of the guide strip 301 and the connecting strip 302, so that the heating tube 304 can be disassembled and installed, thereby facilitating its replacement or maintenance. At the same time, the tape passes through the two sides of the heat-conducting cover 303, which can improve the drying effect and drying speed compared with the traditional tape production equipment in which the tape only passes through one side of the drying device.

A mounting cavity 406 is opened inside the mounting rod 401, and a plurality of tool assemblies are arranged inside the mounting cavity 406. Specifically, when it is necessary to adjust the horizontal position of the mounting rod 401, the third driving motors 403 on both sides are started at the same time to drive the second threaded rods 404 on both sides to rotate, thereby driving the support boxes 402 on both sides to move at the same time, so that the horizontal position of the mounting rod 401 can be adjusted.

It should be noted that the opening width of the mounting cavity 406 should be greater than or equal to the width of the tool holder 408, so that the tool holder 408 can be pulled out from the inner side of the mounting cavity 406.

[0071] See also Figure 8 - Fig.12, an adjusting threaded rod 427 is threadedly connected to the inner side of the mounting block 407, and support plates 429 are rotatably connected at both ends of the adjusting threaded rod 427. The support plate 429 is fixedly installed on the inner side of the mounting cavity 406, and a square hole is opened on the inner side of the adjusting threaded rod 427. A third threaded rod 412 is provided on the inner side of the square hole. A plurality of second guide rods 414 are provided on the outer periphery of the third threaded rod 412. Adjusting square tubes 415 matching the square holes are slidably connected to the outer sides of the plurality of second guide rods 414. Connecting heads 413 are fixed at both ends of the plurality of second guide rods 414. The connecting head 413 is rotatably connected to the inner side of the end of the mounting rod 401, and the third threaded rod 412 is rotatably connected to the inner side of the connecting head 413. An eighth pulley 428 is fixed on the outer side of one end of the mounting rod 401, close to the eighth pulley A third pulley 416 is fixed on the outside of the connecting head 413 at one end of 428, a fourth pulley 417 is fixed on the outside of the end of the third threaded rod 412 close to the third pulley 416, a fourth drive motor 418, a fifth drive motor 421 and a sixth drive motor 424 are installed on the support box 402 close to the end of the eighth pulley 428, a fifth pulley 419 is fixed on the output end of the fourth drive motor 418, the fifth pulley 419 and the outer side of the eighth pulley 428 are connected with a second transmission belt 420, a sixth pulley 422 is fixed on the output end of the fifth drive motor 421, the sixth pulley 422 and the outer side of the third pulley 416 are connected with a third transmission belt 423, a seventh pulley 425 is fixed on the output end of the sixth drive motor 424, The seventh pulley 425 is connected to the outer side of the adjusting threaded rod 427 with a fourth transmission belt 426. Specifically, the plurality of adjusting threaded rods 427 are independent of each other and do not affect each other. The adjusting square tube 415 is set as one. When it is necessary to adjust the position of a certain tool 409 inside the mounting cavity 406, it is necessary to first transport the adjusting square tube 415 to the inner side of the corresponding adjusting threaded rod 427, and then drive the adjusting square tube 415 to rotate to drive the corresponding adjusting threaded rod 427 to rotate. When the adjusting threaded rod 427 rotates, the mounting block 407 on the outer side thereof will perform displacement movement on the outer side of the corresponding adjusting threaded rod 427, thereby adjusting the position of the corresponding tool 409. The specific driving method is as follows: first, the sixth driving motor 424 is started to drive the seventh pulley 425 The fourth drive belt 426 and the fourth pulley 417 drive the third threaded rod 412 to rotate. At this time, the fifth drive motor 421 is stationary, that is, the connecting head 413 and the second guide rod 414 are stationary. Therefore, when the third threaded rod 412 rotates and the second guide rod 414 is stationary, the adjusting square tube 415 is displaced along the second guide rod 414, so that the adjusting square tube 415 is transported to the inner side of the adjusting threaded rod 427 on the inner side of the tool 409 to be adjusted. Then the fifth drive motor 421 and the sixth drive motor 424 are started at the same time. The fifth drive motor 421 drives the connecting head 413 to rotate through the sixth pulley 422, the third drive belt 423 and the third pulley 416, thereby driving the second guide rod 414 to rotate.The third threaded rod 412 rotates synchronously with the second guide rod 414, and then the third threaded rod 412 rotates synchronously with the adjusting square tube 415. At this time, the position of the adjusting square tube 415 on the second guide rod 414 remains unchanged and only rotates with the second guide rod 414. When the adjusting square tube 415 rotates, it drives the adjusting threaded rod 427 on the outside thereof to rotate, thereby driving the tool 409 on the outside thereof to move along the corresponding adjusting threaded rod 427, so as to adjust the position of the corresponding tool 409 inside the mounting cavity 406. When the inclination angle of the tool 409 needs to be adjusted, the fifth drive motor 421, the sixth drive motor 424 and the fourth drive motor 418 are started at the same time. When the fourth drive motor 418 is started, it will drive the fifth pulley 419, the second transmission belt 420 and the fourth drive motor 418 to drive the mounting rod 401 to rotate, so that the third threaded rod 412, the connector 413, the second guide rod 414, the adjustment square tube 415, the mounting block 407 and the mounting rod 401 rotate synchronously, thereby adjusting the inclination angle of the tool 409.

[0072] It should be noted that when there is no adjusting square tube 415 inside the adjusting threaded rod 427, the second guide rod 414 will not interfere with the adjusting threaded rod 427 when rotating in the square hole inside the adjusting threaded rod 427, that is, when the second guide rod 414 rotates, it will not drive the adjusting threaded rod 427 without the adjusting square tube 415 inside to rotate.
