DETAILED DESCRIPTION
[0022] The present application will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present application and not used to limit the scope of the present application. In addition, it should be understood that after reading the content taught by the present application, those skilled in the art can make various changes or modifications to the present application, and these equivalent forms also fall within the scope defined by the present application.
[0023] Embodiment:
[0024] After the film roll processing is completed, in order to further form a product, it is also necessary to cut it into small rolls of corresponding length according to the target product, and the cutting size is different according to different target products (such as different filter cartridges or other products). In the subsequent processing of small rolls within 1m, there may be various sizes of rolls, and their subsequent processing all need to be unwound first and then matched with conveying and post-processing. The model of the unwinding frame and the unwinding roller is fixed now, and can only match the rolls with little size difference, and it is difficult to match the small rolls with more and larger size changes. When the roll is relatively small relative to the unwinding roller, the unwinding process is easy to swing, affecting the stability of the conveying, and is also easy to pull and cause the sheet to wrinkle.
[0025] At the same time, in the unwinding, the sheet often needs to be tensioned, so that it can effectively contact and expand in the subsequent conveying. And the unwinding roller of the small roll has no control function of the unwinding resistance of the roll, and for part of the process, a tensioning roller or a tension control device needs to be added after unwinding, resulting in complex intermediate equipment configuration.
[0026] The design mainly aims at the demand of small multi-size roll releasing, based on the existing workbench, provides a roll clamping tool, the main structure of which comprises two coaxial and opposite first and second conical parts 1 and 2, the tips of which are opposite, so that the position of the roll can be guaranteed unchanged after clamping and positioned during the roll releasing.
[0027] The circumferential surface of the first and second conical parts 1 and 2 is provided with a strip-shaped groove 3 arranged in an annular array, the extension direction of the strip-shaped groove 3 corresponds to the normal line of the first or second conical part 1 or 2, which constitutes a breathable structure with the outer side of the roll core of the roll when being inserted or taken out, facilitating the insertion and extraction.
[0028] The circular end surface of the first conical part 1 away from the second conical part 2 is provided with a rotating seat in the middle, the rotating seat is rotatably connected with a screw rod 5, the screw rod 5 is coaxial with the first conical part 1, one end of the screw rod 5 away from the first conical part 1 is provided with a rotating handle 6, which facilitates the force exertion and screwing operation of the screw rod 5.
[0029] The screw rod 5 is threadedly connected with a threaded sleeve 4, the threaded sleeve 4 is threadedly connected with the screw rod 5, when the screw rod 5 is rotated, the relative distance between the threaded sleeve 4 and the first conical part 1 can be adjusted.
[0030] The threaded sleeve 4 is fixedly connected with a first supporting plate 7 perpendicular to the screw rod 5, one end of the first supporting plate 7 away from the threaded sleeve 4 is provided with a first mounting frame 8.
[0031] The second conical part 2 is provided with a plug 10 which is integrally formed with the second conical part 2 and coaxial with the second conical part 2 on the circular end surface away from the first conical part 1, the plug 10 is a circular truncated cone, the end of the plug 10 connected with the second conical part 2 is the end with larger diameter, and the end of the plug 10 away from the second conical part 2 is the end with smaller diameter and is defined as the insertion end surface, so the peripheral surface of the plug 10 is an inclined annular peripheral surface, the insertion end surface of the plug 10 is provided with a recessed cavity 12, a shaft 11 is arranged in the middle of the recessed cavity 12, a compression spring 13 is further arranged in the recessed cavity 12 and sleeved on the outer part of the shaft 11, a socket 14 is movably inserted on the plug 10, the socket 14 is a cylindrical part, one end of the socket 14 close to the plug 10 is provided with a slot, the bottom of the slot is provided with a through hole for the shaft 11 to pass through, the through hole is adapted to the shaft 11 and can rotate or slide with the shaft 11, an abutment 15 is arranged on the outer end of the shaft 11, the diameter of the abutment 15 is larger than that of the through hole, and the abutment 15 is used to constrain the maximum distance between the plug and the slot. The end of the compression spring 13 away from the second conical part 2 is arranged on the bottom of the slot, so the compression spring 13 has an elastic force to make the plug 10 away from the socket 14, and the plug 10 keeps a relative distance with the socket 14 under no force. The opening edge of the side wall of the slot is provided with a bevel 16, the inclination of the bevel 16 is greater than that of the peripheral surface of the plug 10, and the inner diameter of the bevel 16 at the opening edge is smaller than the maximum diameter of the plug 10, so when the plug 10 is inserted into the slot, the plug 10 is inserted deeper, and the friction between the plug 10 and the socket 14 in the circumferential direction is greater through the cooperation between the peripheral surface of the plug 10 and the bevel 16, so that adjustable resistance can be provided for the rotation of the second conical part 2.
[0032] The peripheral surface of the plug 10 is annularly provided with rubber ridges 17, the extension direction of the rubber ridges 17 is adapted to the normal line of the plug 10, and the rubber ridges 17 are used to increase the friction with the bevel 16 of the slot based on the deformation and the characteristics of rubber.
[0033] The socket 14 is fixedly connected with a second support plate 18 which is perpendicular to the second conical part 2, and the end of the second support plate 18 away from the socket 14 is provided with a second mounting rack 19.
[0034] The structure is used in the following way: the coiled material is placed between the first and second conical members 1 and 2, and the two ends of the coiled core are flush with the first and second conical members 1 and 2, then the screw 5 is rotated to move the first conical member 1 towards the second conical member 2, until the first and second conical members 1 and 2 are inserted into the openings at the two ends of the coiled core, and the coiled material is clamped and fixed. During unwinding, the position of the coiled material is kept unchanged. When the tension of the coiled material needs to be increased, or the resistance to unwinding needs to be increased, the screw 5 is continuously rotated to move the first conical member 1 towards the second conical member 2, so that the coiled material in the middle presses the second conical member 2, the depth of the plug 10 inserted into the socket 14 is increased, the extrusion friction between the plug 10 and the bevel 16 is increased, the resistance to rotation of the second conical member 2 is increased, and the pulling force during unwinding is increased, thus increasing the tension effect.
[0035] The first and second mounting frames 8 and 19 have the following two better and simpler designs in terms of specific structure:
[0036] Design 1: the first mounting frame 8 is a strip-shaped plate member extending in the same direction as the first conical member 1, and the first mounting frame 8 is provided with a first strip-shaped hole 9 corresponding to its length; the second mounting frame 19 is a strip-shaped plate member extending in the same direction as the second conical member 2, and the second mounting frame 19 is provided with a sliding groove 20 on the inner side of the end surface close to the second conical member 2, the first mounting frame 8 is inserted into the sliding groove 20 and is in sliding cooperation with the sliding groove 20, the side wall of the sliding groove 20 is provided with a second strip-shaped hole 21 corresponding to and coinciding with the first strip-shaped hole 9, and the second strip-shaped hole 21 and the first strip-shaped hole 9 are fixed by a bolt member, so that the relative insertion overlap of the first and second mounting frames 8 and 19 can be greatly adjusted, and the distance between the first and second conical members 1 and 2 can be greatly adjusted, thus better adapting to coiled materials of various sizes.
[0037] Design 2: completely free from the constraint of length, the first mounting frame 8 is fixed perpendicularly to the first support plate 7, and the second mounting frame 19 is fixed perpendicularly to the second support plate 18, the first and second mounting frames 8 and 19 are long strip-shaped plate members extending oppositely, the first mounting frame 8 is provided with a first strip-shaped hole 9, and the second mounting frame 19 is provided with a second strip-shaped hole 21, the first and second mounting frames 8 and 19 are fixed at the same height by a bolt member, and the distance therebetween can be installed arbitrarily according to needs, thus adapting to coiled materials of different lengths.
