Description

Technical Field

[0001] This utility model relates to an adhesive application tool, specifically an adhesive tape cutting mechanism and a handheld adhesive applicator. Background Technology

[0002] Applying tape is a common operation in industrial production, packaging, and routine maintenance, but traditional manual tape application methods have the following drawbacks: (1) Inefficient: The process of manually pulling glue, aligning and cutting is cumbersome, especially in batch operations, which is very time-consuming; (2) Insufficient precision: The tape is prone to deviation, wrinkling or uneven stretching, which affects the bonding quality; (3) Inconvenient to operate: It is difficult to control the tension, pasting and cutting of the tape with one hand at the same time, and heavy tape rolls are more likely to cause fatigue; (4) Poor adaptability: Existing adhesive application tools are difficult to be compatible with different widths of tape or to quickly change the roll of material, resulting in insufficient flexibility.

[0003] The prior art patent CN215364160U discloses a tape cutting mechanism and a tape applicator, but the structure is relatively complex and it does not have a tape tension adjustment mechanism or a release paper recycling tray, making it unsuitable for some specific tape application situations.

[0004] While existing automated tape application equipment can partially solve the problem, it generally suffers from drawbacks such as complex structure (e.g., cylinder-driven), large size, and high cost, making it difficult to meet the demands for lightweight and portable operations. Therefore, there is an urgent need for a highly efficient, precise, easy-to-operate, and adaptable handheld tape application device to improve the standardization and automation of tape application.

Detailed Implementation

[0018] Example 1: Please refer to Figures 1-4 This embodiment is a handheld adhesive applicator 100, which includes a support base plate 1, a discharge tray 2, a tensioning assembly 3, a drive wheel 4, an adhesive tape cutting mechanism 5, an adhesive applicator wheel assembly 6 and a recycling tray 7 arranged sequentially along the winding direction of the adhesive tape 200 on the support base plate 1, and a handheld handle 8 fixed on the support base plate 1; the adhesive applicator wheel assembly 6 together form an adhesive applicator surface.

[0019] The support base plate 1 is in a standing position and has a front-facing mounting surface 11. The tensioning assembly 3, the drive wheel 4, the tape cutting mechanism 5, and the adhesive application wheel assembly 6 are all mounted on the mounting surface 11.

[0020] The discharge tray 2 is rotatably mounted on the upper side of the support base plate 1 to supply the tape 200. The discharge tray 2 includes an inner support cylinder 21 rotatably mounted on the support base plate 1 for supporting the inner ring of the tape roll, and a first limiting plate 22 and a second limiting plate 23 oppositely mounted at both axial ends of the inner support cylinder 21. The first limiting plate 22 is fixedly mounted on one side of the inner support cylinder 21, and the second limiting plate 23 is detachably mounted on the other side of the inner support cylinder 21 and locked in place by a locking member 24. Several radially elastically floating elastic compression blocks 25 are provided on the circumferential surface of the inner support cylinder 21 to meet the support requirements of different inner ring diameters of the tray. When changing materials, the operator only needs to unscrew the locking member 24, then remove the second limiting plate 23, then put the tape roll onto the inner support cylinder 21, then press the second limiting plate 23 on and lock the locking member 24 to complete the material change.

[0021] The tensioning assembly 3 is mainly used to maintain a certain tension during the tape application process, preventing the tape from being pulled out excessively due to inertia. The tensioning assembly 3 includes a first support roller 31 rotatably mounted on a support base plate 1 and a tensioning pressure roller 32 elastically floating on the support base plate 1 and cooperating with the first support roller 31 to clamp the tape 200. A first mounting block 33 is fixedly mounted on the support base plate 1. The tensioning pressure roller 32 is rotatably mounted on a pressure roller mounting seat 34, which has a pair of guide rods 341. A linear bearing 35 is mounted on the first mounting block 33. The pressure roller mounting seat 34 is horizontally movable on the first mounting block 33 through the cooperation of the guide rods 341 and the linear bearing 35. An elastic element 36 is provided on the guide rods 341 to abut the tensioning pressure roller 32 against the first support roller 31. By adjusting the compression of the elastic element 36, the clamping force of the tensioning pressure roller 32 on the tape 200 can be adjusted, thereby achieving tension adjustment.

[0022] The recycling tray 7 is rotatably mounted on the support base plate 1 and connected to the drive wheel 4 via a tension rope 9. The adhesive tape 200 is wound around the drive wheel 4. When the adhesive tape 200 moves, it drives the drive wheel 4 to rotate. Under the transmission action of the tension rope 9, the recycling tray 7 is driven to rotate, thereby realizing the follow-up recycling of the release paper. The recycling tray 7 is located on the left side of the support base plate 1.

[0023] A guide wheel 10 is provided on the section of the tape 200 wound between the drive wheel 4 and the tensioning assembly 3, feeding the tape 200, which passes through the tensioning assembly 3, into the drive wheel 4 at a certain angle. A guide groove 101, corresponding to the width of the tape, is provided on the circumferential surface of the guide wheel 10 to ensure effective transmission of the tape 200 and prevent tape deviation.

[0024] The tape cutting mechanism 5 includes a swing plate 51 rotatably mounted on a support base plate 1 at one end, a second support roller 52 rotatably mounted on the swing plate 51, a transmission link 53 hinged to the other end of the swing plate 51, an operating handle 54 rotatably mounted on the support base plate 1 and located below the hand handle 8, a cutter 55 fixed on the support base plate 1 and located above the second support roller 52, and a return member 56 that pulls the free end of the operating handle 54 downward. The other end of the transmission link 53 is hinged to the operating handle 54. When the operator performs the tape cutting operation, they hold the handle 8 and the operating handle 54, using the handle 8 as a support, and lift the operating handle 54 upwards. This causes one end of the transmission linkage 53 to rotate upwards with the operating handle 54. Under the transmission of the transmission linkage 53 and the swing plate 51, the swing plate 51 rotates upwards, which in turn pulls the second support roller 52 on the swing plate 51 upwards. The tape 200 passes around the upper semicircular surface of the second support roller 52. The second support roller 52 is pulled upwards, causing its circumferential surface to move upwards and approach the cutter 55, thus cutting the tape 200. When the operating handle 54 is released, the return member 56 pulls the operating handle 54 downwards. Under the transmission of the transmission linkage 53, the swing plate 51 swings downwards, causing the second support roller 52 to move downwards, so that the tape 200 is disengaged from the cutter 55.

[0025] The support base plate 1 is also provided with a handle limiting shaft 57 that limits the rotation angle range of the operating handle 54 when the return member 56 pulls it down to rotate it downward.

[0026] In this embodiment, a second mounting block 58 for mounting a cutter 55 is provided on the support substrate 1. The cutter 55 is locked onto the second mounting block 58, which can realize quick replacement to be suitable for cutting tapes of various widths.

[0027] The hand handle 8 is fixed to the right side of the support base plate 1, and the operating handle 54 is also located on the right side of the support base plate 1 and below the hand handle 8. When lifting the operating handle 54 upward, the hand handle 8 can be used as a force support to perform the lifting action.

[0028] In this embodiment, the adhesive roller assembly 6 includes at least two adhesive rollers 61. The two adhesive rollers 61 are disposed on the lower side of the support substrate 1. The section formed by the adhesive tape wrapped around the two adhesive rollers 61 is a planar adhesive tape structure, forming an adhesive application plane. When applying the adhesive tape to the target surface, it is only necessary to align the adhesive application plane with the target surface and use the adhesive rollers 61 to press and stick the tape to the target surface.

[0029] To improve the adhesive application reliability of the adhesive application roller assembly 6, a reinforcing connecting rod 62 is provided between the two adhesive application rollers 61 to connect the two adhesive application rollers 61 together.

[0030] In this embodiment, the discharge disc 2 is rotatably mounted on the upper side of the support base plate 1, the hand handle 8 and the operating handle 54 are mounted on the right side of the support base plate 1, the adhesive roller group 6 is mounted on the lower side of the support base plate 1, the recycling disc 7 is mounted on the left side of the support base plate 1, and the tensioning component 3, the drive wheel 4 and the tape cutting mechanism 5 are mounted on the plate surface of the support base plate 1. The overall structure is reasonably laid out and compact.

[0031] An auxiliary handle 20 is also provided on the back of the support substrate 1 to facilitate the operator to hold the adhesive applicator and improve the reliability and stability of the adhesive application process.

[0032] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
