[0039] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without violating the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0040] Secondly, the "embodiment" referred to here means that the specific features, structures or characteristics can be contained in at least one implementation of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or selective embodiment mutually exclusive with other embodiments.

[0041] EMBODIMENT

[0042] Refer to Figures 1-6The embodiment provides a slitting device for adhesive tape production, which comprises a plurality of blades 1, a rack 2, and two rollers 3 rotatably installed on the rack 2, the two rollers 3 form an inclined plane, so that the adhesive tape after passing through the two rollers 3 is in an inclined state, and cutting is more convenient; the slitting device further comprises:

[0043] A sliding block 4 is slidably installed in a waist hole 5 of the rack 2 in a horizontal direction, and the sliding block 4 is between the two rollers 3;

[0044] A fixing rod 6 is arranged in parallel with the two rollers 3;

[0045] A power mechanism 7 is used for driving the sliding block 4 to slide;

[0046] A plurality of cutter assemblies 8 slide along the length direction of the fixing rod 6;

[0047] The cutter assembly 8 comprises:

[0048] A cutter seat 81 is slidably installed on the fixing rod 6 in the length direction of the fixing rod 6, in order to prevent the cutter seat 81 from rotating, the fixing rod 6 is polygonal; the cutter seat 81 is provided with a gap 82 for placing the blade 1; a through hole one 83 in communication with the gap 82 is formed in the side surface of the cutter seat 81; and a through hole two 84 in communication with the through hole is formed in the top surface of the cutter seat 81;

[0049] A pressing block 85 is slidably installed in the through hole one 83, and a slope one 86 is formed on the side, away from the gap 82, of the pressing block 85;

[0050] A driving block 87 is slidably installed in the through hole two 84; a slope two 88 is formed on the bottom of the driving block 87; referring to Figure 4 The slope two 88 is parallel to the slope one 86 and in contact with the slope one 86;

[0051] A screw 89 is rotatably installed in the through hole two 84, and the screw 89 is threadedly connected with the pressing block 85;

[0052] The specific working process of the device is as follows: when it is needed to lock the blade 1, firstly, the blade 1 is placed in the gap 82, one end of the blade 1 protrudes from the gap 82 for cutting, then the screw 89 is rotated, since the screw 89 is threadedly connected with the pressing block 85, with the rotation of the screw 89, the screw 89 pushes the driving block 87 to move downwards, the slope two 88 on the bottom of the driving block 87 contacts the slope one 86 on the pressing block 85, and due to the parallel relationship between the slope two 88 and the slope one 86, vertical pressure is converted into horizontal pressure, so that the blade 1 is tightly pressed and kept stable; when it is needed to release the blade 1, the screw 89 is loosened, since the screw 89 is on the top surface of the cutter seat 81, the blade 1 can be easily replaced, and other cutter seats 81 will not be hindered;

[0053] When the position of the sliding block 4, the fixed rod 6 and the knife seat 81 needs to be adjusted, the power mechanism 7 is operated to move the sliding block 4 along the waist hole 5, and the position of the knife seat 81 and the blade 1 relative to the adhesive tape is changed, so as to adapt to the adhesive tape of different thicknesses, and when the adhesive tape is cut for the first time, the blade 1 can be moved to a position far away from the adhesive tape, and the feeding of the adhesive tape is not affected.

[0054] If the pressing block 85 has no restoring power, the blade 1 may be inconvenient to install, and as a preferred scheme of the utility model, referring to Figures 4-6 , the cutter assembly 8 further comprises:

[0055] The cover plate 810 is fixed to one side of the through hole one 83 away from the notch 82;

[0056] The tension spring 811 has one end connected with the cover plate 810 and the other end connected with the pressing block 85;

[0057] The tension spring 811 is always subjected to tension, when the driving block 87 moves downward, the pressing block 85 approaches the blade 1 to press the blade 1, at this time, the tension spring 811 is further stretched; when the driving block 87 moves upward, under the action of the tension of the tension spring 811, the pressing block 85 can be pulled into the through hole one 83, preventing the blade 1 from being hindered during installation.

[0058] If the cover plate 810 protrudes from the knife seat 81, the distance between the adjacent blades 1 is further increased, which has a certain influence on the slitting width, and as a preferred scheme of the utility model, referring to Figures 4-5 , the one side of the through hole one 83 away from the notch 82 is provided with a sunken groove, and the cover plate 810 is fixed in the sunken groove; by using the sunken groove, the cover plate 810 can be flush with the surface of the knife seat 81 or slightly lower than the surface, ensuring that the relative positions of all the blades 1 are not disturbed by additional factors.

[0059] As a preferred scheme of the utility model, referring to Figure 6 , the pressing block 85 is provided with a plurality of protrusions 812 towards the side of the notch 82, which can increase the friction between the pressing block 85 and the blade 1, so that the blade 1 is more stably fixed.

[0060] If the protrusions 812 are made of hard material, the protrusions 812 may cause the blade 1 to deform or break when pressing the blade 1, and as a preferred scheme of the utility model, the protrusions 812 are made of flexible material, which can be rubber, silicone or the like. Since the flexible material has a certain deformation ability, it can better fit the surface of the blade 1, increase the contact area, and thus improve the fixing effect.

[0061] As a preferred scheme of the utility model, referring to Figure 2 , the power mechanism 7 comprises:

[0062] A power assembly 71 is vertically fixed on the frame 2, and the power assembly 71 has a driving shaft 72 at the output end; the power assembly 71 is a cylinder, an oil cylinder or an electric telescopic rod, etc., and is used for making the driving shaft 72 linearly displace;

[0063] A connecting plate 73 is fixedly connected with the sliding block 4; the connecting plate 73 is provided with an inclined hole 74; the inclined hole 74 has an included angle with the moving track of the driving shaft 72;

[0064] The driving shaft 72 passes through the inclined hole 74;

[0065] The specific working process of the power mechanism 7 is as follows: when the power assembly 71 starts to work, the driving shaft 72 moves up and down along the vertical direction; due to the existence of the inclined hole 74, the movement of the driving shaft 72 in the vertical direction will be converted into the displacement of the connecting plate 73 and the sliding block 4 in the horizontal direction, so as to adjust the position of the roller; and the power assembly 71 is vertically installed, which saves the horizontal space and is helpful for constructing a more compact equipment layout, and is particularly suitable for a production environment with limited space.

[0066] If the driving shaft 72 directly contacts with the inner wall of the inclined hole 74, a large wear will be caused after a long time of use; as an optional scheme of the utility model, a bearing is arranged on the driving shaft 72, the outer ring of the bearing contacts with the inner wall of the inclined hole 74, and the existence of the bearing greatly reduces the direct metal contact between the driving shaft 72 and the inclined hole 74, so as to significantly reduce the frictional resistance therebetween.

[0067] As an optional scheme of the utility model, referring to Figure 3 , the cutter assembly 8 further comprises:

[0068] A threaded handle 813 is threadedly connected with the cutter seat 81, and one end of the threaded handle 813 abuts against the fixed rod 6; by rotating the threaded handle 813, the position of the cutter seat 81 can be adjusted, so as to adjust the distance between the adjacent blades 1.

[0069] It should be understood that, in the development of any actual implementation, numerous implementation-specific decisions can be made. Such development efforts, while possibly complex and time-consuming, would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure, without undue experimentation.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
