DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Please refer to the drawings Figures 1-4 A slitting device of adhesive tape, comprising:

[0026] The workbench 1 is provided with an outer shell 10 detachably connected thereto, two groups of guide assemblies 2 are fixedly connected to the top plate of the outer shell 10, and the slitting part 3 is located between the two groups of guide assemblies 2 and comprises a slitting roller 30, a plurality of slitting assemblies 31, two support frames 32 and a handle 33. The two support frames 32 are fixedly connected to the workbench 1, the slitting roller 30 is bearing-connected at both ends to the two support frames 32, the plurality of slitting assemblies 31 are detachably connected to the curved wall of the slitting roller 30, and one segment of the rotating shaft of the slitting roller 30 passes through the support frame 32 and is fixedly connected to the handle 33.

[0027] The guide assemblies 2 guide the adhesive tape to contact the slitting assemblies 31 on the slitting roller 30, so that the slitting assemblies 31 complete the slitting work of the adhesive tape. Considering that one of the conditions for the slitting work of the slitting assemblies 31 is that the slitting assemblies 31 contact the adhesive tape, the handle 33 is arranged to rotate the slitting roller 30, so as to adjust the position of the slitting assemblies 31.

[0028] Specifically, the slitting roller 30 is provided with a plurality of groups of mounting screw holes 300 uniformly distributed in the axial direction.

[0029] The slitting assembly 31 comprises an arc-shaped knife holder 310 and at least two slitting blades 311, the arc-shaped knife holder 310 is provided with inner countersunk screw holes 3100 at both ends matched with the mounting screw holes 300, the arc-shaped knife holder 310 is provided with at least two groups of blade mounting grooves 3101 in the radial direction, and one end of the slitting blade 311 is detachably connected in the blade mounting groove 3101; considering the working environment of the slitting blade 311 in the process of slitting the adhesive tape, the slitting blade 311 will rise in temperature due to friction, resulting in uneven slitting edges of the adhesive tape, in order to reduce the working time of a single slitting blade 311, at least two groups of slitting blades 311 are arranged on the arc-shaped knife holder 310, and the position of the slitting blade 311 is exchanged by rotating the slitting roller 30 through the rotating handle 33, so as to achieve the purpose of replacing the slitting blade 311, so that the slitting blade 311 with too high temperature of the blade body can be sufficiently cooled, thereby avoiding the uneven slitting edges of the adhesive tape in the slitting process, and considering that different slitting specifications of different adhesive tapes exist, in order to facilitate the adjustment of the position of the slitting assembly 31 and achieve the purpose of slitting the specified size of the adhesive tape, a plurality of mounting screw holes 300 are uniformly distributed on the slitting roller 30, for example, the distance between adjacent two mounting screw holes 300 is 20mm, if the adhesive tape with a width of 40mm needs to be slitted, then two groups of slitting assemblies 31 can be installed with an interval of one mounting screw hole 300, if the adhesive tape with a width of 60mm needs to be slitted, then two groups of slitting assemblies 31 are installed with an interval of two mounting screw holes 300, and meanwhile, considering that the arc-shaped knife holder 310 is installed on the curved surface of the slitting roller 30, if the bolts used for installing the arc-shaped knife holder 310 protrude outside the arc-shaped knife holder 310, the problem of whether the adhesive tape will contact the protruding part of the bolt in the normal working process needs to be considered, and the connecting hole on the arc-shaped knife holder 310 adopts the mode of the inner countersunk screw hole 3100.

[0030] Specifically, the arc-shaped knife holder 310 is provided with a plurality of first through holes 3102 penetrating the blade mounting groove 3101, one end of the slitting blade 311 connected with the arc-shaped knife holder 310 is recessed, and the slitting blade 311 is provided with a second through hole 3110 matched with the first through hole 3102; in order to facilitate the installation of the slitting blade 311, the blade mounting groove 3101 for installing the slitting blade 311 is arranged on the arc-shaped knife holder 310, and in order to facilitate the position fixing of the slitting blade 311, the corresponding first through hole 3102 and second through hole 3110 are also arranged, and the installation of the slitting blade 311 can be completed outside the arc-shaped knife holder 310 through bolts.

[0031] Specifically, the included angle formed by the two adjacent blade installation slots 3101 on the single arc-shaped tool rest 310 and the center of the arc-shaped tool rest 310 is greater than 60°. Considering that the wrapping angle of the slitting roller 30 and the rubber belt is at least 120°, when one of the slitting blades 311 is in contact with the rubber belt and performs slitting, the other slitting blade 311 is in a non-contact state with the rubber belt, and the included angle formed by the two slitting blades 311 and the arc-shaped tool rest 310 is at least 60°. In fact, according to the different heights of the slitting blades 311, the angle is usually 90-135°.

[0032] Specifically, the rotating handle 33 is provided with a locking pin 330 detachably connected thereto, and the support frame 32 close to the rotating handle 33 is provided with a plurality of locking holes 320 matched with the locking pin 330, and the position of the locking hole 320 is matched with the slitting assembly 31. Considering that after the slitting roller 30 is switched by rotating, if no targeted locking is performed, the slitting roller 30 is easily passively rotated during the slitting process, and then the slitting blade 311 is separated from the rubber belt. Therefore, the locking pin 330 is arranged, and the locking hole 320 matched with the slitting assembly 31 is arranged on the support frame 32. For example, the included angle formed by two groups of slitting blades 311 and the center is 90°, and then at least two locking holes 320 are needed, and the included angle formed by the two locking holes 320 and the center should also be 90°.

[0033] Specifically, the guide assembly 2 includes two guide supports 20 and a guide roller 21. One end of the two guide supports 20 is fixedly connected to the top plate of the outer shell 10, and the two ends of the guide roller 21 are bearing-connected to the ends of the guide supports 20 away from the top plate of the outer shell 10. In order to ensure that the rubber belt can be in contact with the slitting blade 311 and complete the slitting of the rubber belt through the slitting blade 311, two groups of guide assemblies 2 are arranged to ensure that the running direction of the rubber belt is in a wave shape.

[0035] Please refer to the attached Figures 5-6

[0036] In view of the fact that the gel on the adhesive tape will stick to the cutting blade 311 during the long time slitting process, if the gel is not cleaned, the slitting quality of the cutting blade 311 will be affected, specifically, the support frame 32 is provided with a cleaning strip 34, the cleaning strip 34 is detachably connected to the lower end of the support frame 32, and a plurality of cleaning grooves 340 matched with the cutting blade 311 are arranged on the cleaning strip 34; when the cutting blade 311 is rotated by rotating the slitting roller 30, the cutting blade 311 passes through the cleaning grooves 340 when rotating to the position of the cleaning strip 34, and the cleaning of the cutting blade 311 is completed by the edge of the cleaning grooves 340, it should be noted that the cleaning grooves 340 can adopt a tapered groove (such as the enlarged cleaning groove 340 shown in the figure), which can not only clean the cutting blade 311, but also slightly correct the position of the cutting blade 311.
