[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] like Figure 1-5 As shown, a tape cutting and reeling device comprises a base 1, on which are arranged:

[0025] The bearing seat 11 is provided with a concave arc groove 111 for accommodating the film raw material, and the bearing seat 11 is also provided with a cutting groove 112;

[0026] The cutting seat 2 is vertically slidably arranged relative to the bearing seat 11 , and the blade 21 arranged on the cutting seat 2 is vertically aligned with the cutting groove 112 .

[0027] Specifically, Figure 1As shown, a concave arc groove 111 is provided on the bearing seat 11 of the base 1, and a push rod 4 is also provided on the base 1 to slide axially along the concave arc groove 111, so that the film material can be placed in the concave arc groove 111, and the push rod 4 is used to move the film material, and the cutting seat 2 slides vertically to make the blade 21 vertically close to the cutting groove 112 to cut and shape the film material, thereby cutting the film material into molded rolls of different thicknesses, and the concave arc groove 111 and the cutting groove 112 provided on the bearing seat 11 are used to make the film material located in the concave arc groove 111 move axially toward the cutting seat 2 for loading, and the film material located in the concave arc groove 111 can be automatically centered by gravity to be coaxial with the concave arc groove 111, thereby avoiding the problem of abnormal shape of the film formed after cutting caused by rolling and skewing of the film material during the loading process.

[0028] In the above technical solution, the concave arc groove 111 and the cutting groove 112 provided on the supporting seat 11 are utilized so that the film raw material is located in the concave arc groove 111 and is axially moved toward the cutting seat 2 for loading. Moreover, the film raw material located in the concave arc groove 111 can be automatically centered to be coaxial with the concave arc groove 111 due to gravity, thereby avoiding the problem that the film raw material rolls and tilts during the loading process, causing the abnormal shape of the film formed after cutting.

[0029] As an embodiment further provided by the present invention, a fixing assembly 3 is arranged on the supporting seat 11, and the fixing assembly 3 includes a fixing seat 31 vertically slidably arranged on the supporting seat 11, and the fixing seat 31 has a cross beam portion 311 and a convex arc portion, and a resistance portion 22 is arranged on the cutting seat 2. The cutting seat 2 is driven to slide relative to the concave arc groove 111 so that the resistance portion 22 pushes the cross beam portion 311 to move close to the concave arc groove 111, and the convex arc portion and the supporting seat 11 clamp the film material.

[0030] Specifically, Figure 2 As shown, a sliding portion 314 is provided on the fixing seat 31 of the fixing assembly 3, and a first sliding groove 113 is provided on the supporting seat 11. The sliding portion 314 is slidably arranged in the first sliding groove 113 so that the fixing seat 31 is located on the supporting seat 11 and slides vertically. A second elastic member 32 is also provided in the first sliding groove 113 so that the fixing seat 31 is vertically slid and moved upward to a high position by the second elastic member 32. When the cutting seat 2 is driven to move vertically downward to cut the film material, the abutting portion 22 first abuts against the crossbeam portion 311 so that the convex arc portion of the fixing seat 31 moves downward and clamps the film material with the supporting seat 11, and then the blade portion 21 cuts the film material into a roll, so that the fixing seat 31 is used to clamp and fix the film material first, and then the cutting seat 2 cuts the film material, thereby further avoiding the deformation problem of the cut and formed roll caused by the sliding of the film material, thereby improving the cutting and forming quality.

[0031] The second elastic member 32 may be a spring, an elastic plate, an air bag or other elastic objects known to those skilled in the art.

[0032] As an embodiment further provided by the present invention, a resistance member 51 and a first elastic member 52 are provided on the resistance portion 22 . The resistance member 51 is vertically slidably arranged and driven by the first elastic member 52 to be in a low position by default. The resistance member 51 is vertically aligned with the cross beam portion 311 .

[0033] Specifically, Figure 3 As shown, a resistance member 51 and a first elastic member 52 are provided on the resistance portion 22, and the first elastic member 52 pushes the resistance member 51 to slide vertically in the second sliding groove 221 of the cutting seat 2. When the cutting seat 2 moves vertically downward, the resistance member 51 follows the cutting seat 2 to move vertically downward and resists on the crossbeam portion 311. When the fixed seat 31 clamps the film material in the concave arc groove 111, the cutting seat 2 continues to move vertically downward to compress the first elastic member 52, so as to utilize the first elastic member 52 to further enhance the clamping stability of the fixed seat 31 on the film material. Secondly, the first elastic member 52 is utilized to enable the resistance member 51 to slide vertically, so that the fixed seat 31 can clamp and fix film materials of different diameters, thereby improving the applicability of the device.

[0034] The first elastic member 52 may be a spring, an elastic plate, an air bag or other elastic objects known to those skilled in the art.

[0035] As an embodiment further provided by the present invention, a storage chamber 312 for storing alcohol is provided in the fixed seat 31, a spray outlet 313 connected to the storage chamber 312 is provided on the convex arc portion of the fixed seat 31, and a flexible extrusion member 8 with one end located in the storage chamber 312 is provided on the crossbeam portion 311, wherein the cutting seat 2 moves vertically so that the abutment member 51 abuts against the flexible extrusion member 8 in a default state, and the blade portion 21 is horizontally aligned with the spray outlet 313.

[0036] Specifically, Figure 5 As shown, alcohol can be pre-stored in the storage chamber 312 in the fixed seat 31. When the cutting seat 2 moves vertically downward so that the abutment 51 abuts against the flexible extrusion member 8, the blade 21 is horizontally aligned with the ejection port 313. When the cutting seat 2 continues to move vertically downward, the abutment 51 squeezes the flexible extrusion member 8 to deform into the storage chamber 312, and then the alcohol is ejected along the ejection port 313 onto the blade 21, so that the blade 21 is sprayed with alcohol, thereby avoiding the problem of the adhesive tape sticking to the blade during the cutting process, resulting in a decrease in cutting efficiency, and improving the quality of the molded product. Secondly, the alcohol can also evaporate to take away the heat on the blade 21, thereby avoiding the problem of the blade 21 sticking due to excessive temperature during continuous cutting operations.

[0037] Furthermore, a spray head may be provided on the spray port 313 to improve the spraying uniformity of the alcohol and prevent the alcohol from gathering in large droplets on the blade 21 .

[0038] As a further embodiment of the present invention, a rotating wheel 6 is symmetrically arranged on the convex arc portion of the fixing seat 31 , and the fixing seat 31 is driven to slide close to the concave arc groove 111 so that the rotating wheel 6 pushes the film material to be centered in the concave arc groove 111 .

[0039] Specifically, a rotating wheel 6 is symmetrically arranged on the convex arc portion of the fixing seat 31. When the fixing seat 31 is driven by the cutting seat 2 to slide close to the concave arc groove 111, the rotating wheel 6 moves vertically downward to push the film material to be centered in the concave arc groove 111, so as to utilize the rotating wheel 6 to further improve the centering of the film material when it is clamped and cut, thereby improving the product molding quality.

[0040] As an embodiment further provided by the present invention, one end of the rotating wheel 6 is located in the storage cavity 312 , and a flexible blocking member 7 is provided on the fixing seat 31 to abut against two sides of the rotating wheel 6 , and an axial accommodating groove 61 is provided in a circumferential array on the rotating wheel 6 .

[0041] Specifically, Figure 5 As shown, the upper end of the rotating wheel 6 is located in the storage cavity 312, and the flexible sealing members 7 are arranged on both sides of the rotating wheel 6 to prevent the alcohol liquid in the storage cavity 312 from leaking out. However, when the rotating wheel 6 moves vertically downward to push the film material to be centered in the concave arc groove 111, the rotating wheel 6 will inevitably rotate. Therefore, during the rotation of the rotating wheel 6, the alcohol in the storage cavity 312 will be located in the accommodating groove 61 and partially leak out to the surface of the film material following the rotation of the rotating wheel 6, thereby avoiding the problem that the surface colloid of the film material sticks to the fixing seat 31 and causes the film material to rise with the fixing seat 31, thereby facilitating the continuous cutting and molding of the film material.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
