Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of adhesive tape indentation, especially to the indentation device based on adhesive tape production. BACKGROUND

[0002] Adhesive tape is a common band-shaped material with adhesion, usually composed of two parts: substrate and adhesive. The substrate can be a plastic film such as BOPP (biaxially oriented polypropylene), PET (polyethylene terephthalate), etc., or paper, cloth, etc., providing basic strength and flexibility for the adhesive tape. The adhesive gives the adhesive tape adhesion, allowing it to be pasted on various object surfaces. Common adhesives include acrylate adhesives, rubber adhesives, etc. Adhesive tape has a wide range of uses. In daily life, it can be used for packaging, pasting paper, repairing objects, etc.; in the industrial field, it can be used for fixing electronic components, assembling automobile parts, sealing building materials, etc.; in the office environment, it is used for file packaging, object marking, etc. In short, with its convenient and efficient pasting function, adhesive tape has become an indispensable item in people's lives and work.

[0003] Setting indentation on adhesive tape has the effects of facilitating use and improving performance. From the perspective of facilitating use, indentation allows the adhesive tape to be easily torn in the desired direction when stretched, making it easy for users to obtain the appropriate length of adhesive tape without the need for scissors or other tools, greatly improving the convenience and efficiency of use. Moreover, with indentation, the adhesive tape is smoother during winding and unwinding, reducing the adhesion and jamming between the adhesive tapes. In terms of improving performance, indentation can increase the adhesion of the adhesive tape to the surface of the object being pasted, allowing the adhesive tape to better adapt to the shape of the object surface and enhance the adhesion strength. At the same time, indentation can also disperse the external force on the adhesive tape to some extent, improving the adhesive tape's resistance to stretching and tearing, making it less likely to break during use, and thus better performing its sealing and fixing functions.

[0004] However, some existing adhesive tapes cannot effectively adjust the tension during indentation operation. During the operation of the indentation equipment, the adhesive tape needs to maintain a relatively stable and appropriate tension, which ensures that the indentation falls accurately on the predetermined position. However, when the tension cannot be adjusted, the adhesive tape may shift left and right and vibrate during transmission due to unstable tension. This directly causes the indentation position to deviate from the preset position when acting on the adhesive tape, resulting in significant deviation. Once the indentation position deviates, it will seriously affect the indentation effect, and the subsequent use of the adhesive tape will be greatly compromised, such as irregular tearing when tearing and difficulty in close adhesion when pasting, reducing the practicality and quality of the adhesive tape. Therefore, to address the above shortcomings, an indentation device based on adhesive tape production is proposed to solve the above problems. SUMMARY

[0005] To overcome the above shortcomings, this utility model provides an indentation device based on tape production, which aims to improve the problem that some indentation devices for tape production in the prior art cannot achieve tension adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The creasing device based on tape production includes a housing, a top frame fixedly connected to the top of the housing, a motor installed inside the top frame, a drive shaft fixedly connected to the output end of the motor, a gear fixedly connected to the outside of the drive shaft, multiple sliding grooves on the left side of the inside of the housing, two connecting rods slidably connected inside the housing, tension rollers fixedly connected to the outside of each of the two connecting rods, racks fixedly connected to the top of each of the two connecting rods, limit shafts fixedly connected to the opposite sides of each of the two racks, and limit plates fixedly connected to the bottom of each of the two connecting rods. Limit grooves are opened on the left and right sides of the inside of the top frame, a creasing assembly for creasing is provided on the right side of the inside of the housing, and a winding assembly for winding the tape is provided on the right side of the inside of the housing.

[0008] As a further description of the above technical solution:

[0009] The outer shell has two sliding rods slidably connected to both the front and rear sides. Each of the sliding rods is fitted with a spring. Each of the sliding rods has a limiting plate fixedly connected to the opposite side. The outer shell has two triangular scrapers slidably connected inside. The bottom of the outer shell is fixedly connected to a collection box.

[0010] As a further description of the above technical solution:

[0011] The indentation assembly includes a second motor, the bottom of which is mounted on the top right side of the housing. A second drive shaft is fixedly connected to the output end of the second motor. An indentation roller is fixedly connected to the outside of the second drive shaft. A second gear is fixedly connected to the bottom of the second drive shaft. A rotating shaft is rotatably connected to the inside right side of the housing. A rotating roller is fixedly connected to the outside of the rotating shaft. A third gear is fixedly connected to the bottom right side of the housing. A protective shell is fixedly connected to the bottom right side of the housing.

[0012] As a further description of the above technical solution:

[0013] The winding assembly includes a motor three, the output end of which is fixedly connected to a drive shaft three, and a winding roller is fixedly connected to the outside of the drive shaft three.

[0014] As a further description of the above technical solution:

[0015] The connecting rod is externally slidably connected to the inside of the groove, and the tensioning roller is externally slidably connected to the inside of the housing;

[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The second gear and the third gear are meshed together, and the external part of the indentation roller is rotatably connected to the inside of the outer casing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, motor one serves as the power source, driving drive shaft one and gear one to rotate. Gear one meshes with rack and pinion, converting the rotational motion into the linear motion of the rack and pinion, which in turn drives the connecting rod and tension roller to move. By controlling the forward and reverse rotation of motor one, the two tension rollers can be moved closer or further apart simultaneously. The distance between the two tension rollers can be flexibly adjusted according to the material, width, and production process requirements of the tape, thereby precisely adjusting the tension of the tape during transmission. This effectively avoids problems such as uneven indentation, tape stretching deformation, or even breakage caused by improper tape tension, ensuring the quality and stability of tape indentation and winding, and improving the product qualification rate.

[0024] 2. In this invention, the spring force is used to keep the tip of the triangular scraper in constant contact with the tape surface. The two triangular scrapers are set at an angle to accommodate changes in the tape's position during tension adjustment. During tape transport, the tips of the triangular scrapers scrape against the tape surface, removing dust, impurities, and other adhering substances. These substances eventually fall into the collection box, effectively ensuring the cleanliness of the tape surface, preventing surface impurities from affecting the creasing quality, ensuring good contact between the creasing roller and the tape surface, resulting in a clearer and more uniform creasing effect, and improving product quality.

A top frame 2 is fixedly connected to the top of the housing 1, and a motor 3 is installed inside the top frame 2. The motor 3 is a power source for adjusting the tension of the tape. A drive shaft 4 is fixedly connected to the output end of the motor 3, and a gear 5 is fixedly connected to the outside of the drive shaft 4. The drive shaft transmits the rotational power of the motor 3 to the gear 5. Multiple sliding grooves 6 are provided on the left side of the interior of the housing 1.

Tensioning rollers 8 are fixedly connected to the outside of each of the two connecting rods 7, and the outside of the tensioning rollers 8 is slidably connected inside the housing 1. The tensioning rollers 8 are used to adjust the tension of the tape during transmission. Both connecting rods 7 are fixedly connected to the top of racks 9. Gear 5 is meshed with racks 9. Gear 5, through meshing with racks 9, converts the rotational motion of drive shaft 4 into linear motion of racks 9, thereby driving the connecting rods 7 and tension roller 8 to move, thus adjusting the position of tension roller 8. Limiting shafts 10 are fixedly connected to the opposite sides of the two racks 9. Limiting shafts 10 limit the direction of movement of racks 9 and prevent them from deviating. Limiting plates 11 are fixedly connected to the bottom of both connecting rods 7. Limiting grooves 12 are opened on the left and right sides of the inside of the top frame 2. The outside of the limiting shaft 10 is slidably connected to the inside of the limiting groove 12. The limiting groove 12 provides guidance and limiting for the limiting shaft 10. An indentation assembly for indentation is provided on the inside right side of the outer casing 1, and a winding assembly for winding tape is provided on the inside right side of the outer casing 1.

[0034] Reference Figures 2 to 4 The housing 1 has two sliding rods 24 slidably connected to both the front and rear sides, which guide the movement of the triangular scraper 27. Each sliding rod 24 is fitted with a spring 25. One end of the spring 25 is fixedly connected to the side of the triangular scraper 27 near the limiting disc 26, and the other end is fixedly connected to the inside of the housing 1. The spring 25 provides elasticity, allowing the tip of the triangular scraper 27 to press firmly against the tape surface, effectively removing adhering substances from the tape surface. Limiting discs 26 are fixedly connected to the opposite sides of the sliding rods 24. The housing 1 also has two slidably connected triangular scrapers 27, which scrape the tape surface before indentation to remove adhering substances. Both triangular scrapers 27 are angled to accommodate tape tension adjustment. A collection box 28 is fixedly connected to the bottom of the housing 1 to collect the adhering substances scraped off by the triangular scrapers 27.

[0035] Reference Figure 2 , Figure 3 and Figure 5The creasing assembly includes a second motor 13, the bottom of which is mounted on the top right side of the housing 1. The motor 13 is the power source for the creasing assembly. A drive shaft 14 is fixedly connected to the output end of the motor 13. A creasing roller 15 is fixedly connected to the outside of the drive shaft 14, transmitting the rotational power of the motor 13 to the creasing roller 15. The creasing roller 15 is rotatably connected to the inside of the housing 1. The creasing roller 15 is the core structure for creasing the tape, and its surface is specially processed according to the required creasing shape and size, such as engraving specific patterns or grooves. A gear 16 is fixedly connected to the bottom of the drive shaft 14, rotating synchronously with it. A rotating shaft 17 is rotatably connected to the inside right side of the housing 1, and a rotating roller 18 is fixedly connected to the outside of the rotating shaft 17. The rotating roller 18 cooperates with the creasing roller 15 to creasing the tape. Gear 19 is fixedly connected to the bottom of the rotating shaft 17. Gear 16 and gear 19 are meshed together. Gear 19 converts the power transmitted by gear 16 into the rotational power of the rotating shaft 17 and the rotating roller 18. A protective shell 20 is fixedly connected to the bottom right side of the outer casing 1. The protective shell 20 is mainly used to protect the gears and prevent accidental contact by operators and damage from external objects. The winding assembly includes motor 21, which is the power source of the winding assembly and is used to drive the winding roller 23 to rotate and wind up the creasing tape. A drive shaft 22 is fixedly connected to the output end of motor 21. A winding roller 23 is fixedly connected to the outside of drive shaft 22. The winding roller 23 is used to wind the creasing tape.

[0036] Working principle: When creasing the tape, motor 3 first drives drive shaft 4 and gear 5 to rotate. The meshing between gear 5 and rack 9 causes the two racks 9 to shift, moving them closer or further apart simultaneously. This allows adjustment of the tape tension during transport based on the distance between the two tension rollers 8. The tape then passes through the left side of one tension roller 8, around the right side of the other, and finally between the creasing roller 15 and the rotating roller 18, winding onto the outside of the take-up roller 23. Motor 213 then drives drive shaft 214 and the creasing roller 15 to rotate, simultaneously driving gear 216... The belt rotates, and the meshing of gear 16 and gear 19 causes gear 19 to rotate, which in turn drives the rotating roller 18 to rotate. The rotation of the creasing roller 15 and the rotating roller 18 then creasing the tape. Finally, motor 21 drives the take-up roller 23 to rotate and take up the creasing tape. Before creasing the tape, two triangular scrapers 27 scrape the surface of the tape. Both triangular scrapers 27 are inclined to accommodate tape tension adjustment. At the same time, the elastic force of spring 25 allows the tips of the triangular scrapers 27 to stick to the surface of the tape, thereby removing the adhering substances from the tape surface. Finally, the tape falls into the collection box 28 for collection.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
