[0028] Example:

[0029] The utility model provides a device for cutting adhesive tape to a fixed length, which aims to solve the technical problems in the prior art that the cutting blade is exposed, which poses a safety hazard, and the adhesive tape is easy to rewind after being cut;

[0030] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0031] A device for cutting adhesive tape to a fixed length comprises a support platform 1, a tape placement rack 101 is fixedly connected to one side of the top of the support platform 1, a sleeve rod 102 is fixedly connected to the inside of the tape placement rack 101, a threaded groove 1021 is provided at one end of the sleeve rod 102, a film roll 103 is sleeved on the outer side of the sleeve rod 102, one end of the sleeve rod 102 with the threaded groove 1021 is threadedly connected to a limiting block 104, a threaded strip 1041 is fixedly connected to the position of the limiting block 104 corresponding to the threaded groove 1021, and the limiting block 104 is connected to the threaded strip 1041 through the threaded strip 1041. The threaded groove 1021 is threadedly connected to limit the film 103 sleeved on the sleeve rod 102 to prevent the film 103 from slipping out of the tape placement rack 101 during use. The side of the limit block 104 away from the threaded strip 1041 is fixedly connected to the handle head 1042, and the handle head 1042 drives the limit block 104 for loading and unloading. Support feet 105 are fixedly connected to both sides of the bottom of the support platform 1. The support feet 105 provide support for the bottom of the support platform 1. The bottom of the support feet 105 is provided with anti-skid pads, which enhance the contact stability between the support feet 105 and the ground.

[0032] Among them, see Figure 1 , Figure 2 and Figure 3The top of the support platform 1 and one side away from the tape placement rack 101 is fixedly connected with a bracket 2, and one side of the bracket 2 is rotatably connected with a fixed-length block 201. The fixed-length block 201 is designed in a cross-shaped structure, which effectively reduces the contact area between the tape and the fixed-length block 201, making it easy to tear off the cut tape. The cut section of the tape is bonded to the fixed-length block 201, which can also prevent the tape from rolling back after cutting. The corners of the fixed-length block 201 are all provided with cutting knife grooves 2011, which are convenient for freely adjusting the cutting length of the tape. 1 is fixedly connected to limit strips 2012 on both sides, and the limit strips 2012 limit the two sides of the tape to avoid position deviation and affect the cutting effect. A strip groove 202 is provided on the top of the support table 1 and below the fixed-length block 201, and a rotating handle 203 is provided at the center of the fixed-length block 201 and on the side away from the bracket 2. The rotating handle 203 drives the fixed-length block 201 to pull out and reel the tape, and the outer side of the rotating handle 203 is provided with anti-skid grooves, which improve the anti-skid property of the rotating handle 203.

[0033] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A tool holder 3 is provided at the bottom of the support platform 1 and below the strip groove 202. A cutting blade 301 is fixedly connected to the top of the tool holder 3 and at a position corresponding to the strip groove 202. An arc-shaped pressing groove 302 is provided at the bottom of the tool holder 3. The staff applies an upward force to the tool holder 3 through the arc-shaped pressing groove 302, driving the cutting blade 301 to pass through the strip groove 202 and insert it into the corresponding cutting knife groove 2011 to cut the tape to a fixed length.

[0034] For further information, see Figure 2 and Figure 4 A pair of elastic mechanisms 4 are installed on both sides of the top of the tool holder 3. The tool holder 3 is connected to the support platform 1 through the elastic mechanism 4. The elastic mechanism 4 is composed of a telescopic rod 401 and a reset spring 402. The outer side of the telescopic rod 401 is provided with a reset spring 402. After the tape is cut, the elasticity of the reset spring 402 drives the telescopic rod 401 to retract and reset, so that the cutting blade 301 performs a reset movement and returns to the bottom of the support platform 1, avoiding the safety hazard caused by the exposure of the cutting blade 301.

[0035] The working process of the utility model is as follows: first, the film 103 is sleeved on the sleeve rod 102, and the handle head 1042 drives the limit block 104 to be threadedly connected with the thread groove 1021 through the thread strip 1041, so as to limit the film 103 sleeved on the sleeve rod 102 to prevent the film 103 from slipping out of the tape placement rack 101 during use, and a section of the tape on the film 103 is pulled out and bonded to the fixed length block 201, and the handle 203 is rotated to drive the fixed length block 201 to pull out the tape according to the required length. During winding, the blade holder 3 is forced upward through the arc-shaped pressing groove 302, and the telescopic rod 402 is contracted by the force of the reset spring 401, so that the cutting blade 301 passes through the strip groove 202 and is inserted into the corresponding cutting knife groove 2011 to cut the tape to a fixed length. After the tape is cut, the elasticity of the reset spring 402 drives the telescopic rod 401 to retract and reset, so that the cutting blade 301 performs a reset movement and returns to the bottom of the support platform 1, thereby avoiding the safety hazard caused by the cutting blade 301 being exposed.

[0036] The entire operation process is simple and convenient. Compared with the existing cutting device, the utility model can avoid the exposure of the cutter through design, improve the overall safety and convenience of use, and avoid the tape from rolling back after cutting, thereby enhancing the overall practicality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
