[0023] Reference Figures 1 to 4The embodiment of the utility model provides a ribbon slitting machine, including a frame 100, a guide roller group, a conveying roller 210 group, a slitting assembly and a feeding roller 500. A reeling device 110 is provided at one end of the frame 100. The ribbon to be slit is usually a roll and needs to be unwound by the reeling device 110; the guide roller group is connected to the frame 100 and is located on the right side of the reeling device 110. The guide roller group has a plurality of conveying rollers 210. The conveying rollers 210 are connected to a motor to achieve rotation, thereby driving the ribbon to move; the conveying roller group is connected to the frame 100 and is located on the right side of the guide roller group. The conveying rollers 210 The group includes an active roller 310 at the top and a driven roller 320 at the bottom. The active roller 310 and the driven roller 320 cooperate to clamp the webbing for conveying, accurately position the height of the webbing, and cooperate with slitting; the slitting assembly is connected to the frame 100 and is located on the right side of the conveying roller 210 group. The slitting assembly includes a supporting seat 410, a cutter seat 420 and a driving member 430. The upper end surface of the supporting seat 410 is provided with a slitting groove 411. The driving member 430 is fixed to the frame 100 and can drive the cutter seat 420 to rise and fall. The driving member 430 can be a cylinder, an oil cylinder or an electric push rod, etc., without limitation. The cutter 421 seat 420 is located directly above the supporting seat 410, and the cutter 421 seat 420 is provided with a cutter 421 and two belt pressing components. The cutter 421 can be inserted into the slitting groove 411, and the two belt pressing components are distributed on both sides of the cutter 421. The belt pressing components cooperate with the supporting seat 410 to press the ribbon; the unloading roller 500 is connected to the frame 100 and is located on the right side of the slitting assembly. The frame 100 is provided with a support plate 120, and the unloading roller 500 is located above the support plate 120. The unloading roller 50 is connected to a motor to realize rotation, and the rotating unloading roller 500 and the support plate 120 cooperate to convey the slit ribbon.

[0024] The webbing is unwound by the unwinding device 110, and the webbing first passes around the multiple conveying rollers 210 of the guide roller group so that the webbing is smoothly stretched and conveyed, and then the active roller 310 and the driven roller 320 of the conveying roller group cooperate to clamp the webbing, and the webbing is sent to the supporting seat 410 through the rotation of the active roller 310 to accurately locate the height of the webbing. When the length of the webbing reaches the set size, the unwinding device 110, the guide roller group and the conveying roller group stop, and the active roller 310 and the driven roller 320 clamp the webbing, and the driving member 430 pushes the cutter 421 seat 420 to descend, and the two belt pressing components and the supporting seat 410 cooperate to clamp the webbing to prevent the webbing from deflecting, and then the cutter 421 cuts the webbing, which is conducive to accurate slitting of the webbing. The slitting webbing is transported through the unloading roller 500 and the support plate 120 to complete the unloading.

[0025] It is understandable that the two belt pressing components can be pressed on the upper end surface of the supporting seat 410, or can be pressed on the side surface of the supporting seat 410, as long as the webbing can be limited.

[0026] Reference Figure 2In some embodiments of the utility model, the tape pressing component includes a support plate 422 and an elastic ball 423. The upper end of the support plate 422 is fixed to the cutter seat 420, and the lower end of the support plate 422 is fixedly connected to the elastic ball 423. The elastic ball 423 fits tightly with the side wall of the support seat 410 to compress the tape. It can be understood that the elastic ball 423 and the support seat 410 are interference fit. When they contact each other, the elastic ball 423 is slightly deformed so that it can fit tightly with the support seat 410 to achieve the purpose of compressing the tape. After the slitting is completed, the cutter seat 420 rises, the elastic ball 423 separates from the support seat 410, and the tape is driven by the elastic ball 423 to rise a certain distance, and then automatically falls on the support seat 410, and is then transported away by the unloading roller 500 and the support plate 120.

[0027] The elastic ball 423 is usually made of silicone or rubber, which is easy to shape and has controllable elasticity. The support plate 422 can be a metal part, and the support plate 422 and the elastic ball 423 are integrally formed. The support plate 422 can also be a plastic part, and the support plate 422 and the elastic ball 423 are assembled as a whole. The surface of the elastic ball 423 is provided with anti-slip grooves, and the elastic ball 423 abuts against the supporting seat 410, which can better compress the webbing.

[0028] Reference Figure 3 and Figure 4 In some other embodiments of the present invention, the belt pressing component includes a support plate 422 and an eccentric wheel 424. The upper end of the support plate 422 is fixed to the cutter seat 420. The lower end of the support plate 422 is provided with a rotating shaft 425. The eccentric wheel 424 is connected to the rotating shaft 425. The eccentric wheel 424 can abut against the side wall of the supporting seat 410. Figure 4 As shown, when the cutter seat 420 descends, the eccentric wheel 424 contacts the webbing and the supporting seat 410. Due to the friction force, the eccentric wheel 424 rotates around the rotating shaft 425. Since the eccentric wheel 424 is an eccentric structure, the eccentric wheel 424 and the supporting seat 410 are closely fitted, thereby clamping the webbing. By controlling the descending distance of the cutter seat 420, the degree of clamping can be controlled. After the slitting is completed, the cutter seat 420 rises, the eccentric wheel 424 rotates, and separates from the supporting seat 410. The webbing will be separated from the eccentric wheel 424, and then automatically falls on the supporting seat 410, and then transported away by the unloading roller 500 and the support plate 120.

[0029] The eccentric wheel 424 may be made of silicone or rubber material, and a plurality of parallel anti-slip grooves are provided on the outer peripheral wall of the eccentric wheel 424, which is conducive to better clamping the webbing and preventing the webbing from shifting.

[0030] It can be understood that in some embodiments of the present invention, the cutter 421 seat 420 can also be provided with an electric heating component, which is used to heat the cutter 421. During slitting, for some special material webbings, such as plastic webbings, the high-temperature cutter 421 can quickly cut the webbing, reduce adhesion, improve the size accuracy of the slit webbing, and improve product quality.

[0031] Reference Figure 1 and Figure 2 In some embodiments of the utility model, the unloading roller 500 is connected to a cylinder 510, and the cylinder 510 is fixed on the frame 100. The unloading roller 500 is driven to rise and fall by the cylinder 510. The cylinder 510 has a simple structure, low cost, and is easy to use.

[0032] Reference Figure 1 and Figure 2 In some embodiments of the utility model, the height of the support plate 120 is lower than the upper end surface of the support seat 410, which is conducive to the webbing after slitting falling on the support plate 120, and the support plate 120 is provided with a plurality of suction holes, and the plurality of suction holes are arranged at intervals along the conveying direction of the webbing. The support plate 120 is connected to a fan to generate suction in the suction holes, and the unloading roller 500 is pressed on the webbing, and the webbing is driven to move by the rotation of the unloading roller 500. The suction holes help position the webbing to prevent the webbing from flying. It can be understood that before slitting, the conveying roller group conveys the webbing over the support seat 410 and enters the support plate 120, the cylinder 510 is in a high position, and then the cylinder 510 drives the unloading roller 500 to move downward to press the webbing.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
