Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of slitting devices, and in particular relates to a slitting device for producing self-adhesive labels. Background Technology
[0002] In the self-adhesive label manufacturing industry, the performance of slitting equipment plays a decisive role in product quality and production efficiency. Currently, the market demand for self-adhesive labels is becoming increasingly diversified, placing stringent requirements on slitting equipment.
[0003] Traditional self-adhesive label slitting devices suffer from numerous problems regarding slitting accuracy. Many devices have poorly designed slitting structures, making it difficult to guarantee the stability of the slitting process. Inappropriate contact methods between the cutting blade and the material being cut cause material displacement and vibration during the cutting process.
[0004] The winding process is also a weakness of traditional slitting devices. Most traditional slitting devices use a single-station winding design. After one winding roller completes winding, the paper tube needs to be manually replaced and the winding process restarted. This process is not only time-consuming but also interrupts production, greatly reducing production efficiency. Furthermore, single-station winding cannot adapt to the large-scale, high-efficiency pace of modern production.
[0005] Therefore, it is essential to invent a slitting device for producing self-adhesive labels. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a slitting device for self-adhesive label production, including a conveying roller, a slitting roller, an outer frame, an inner frame, an outer frame plate, a multi-station winding device, a paper tube, a bracket, a station motor, a cutting disc, and a cutting wheel. The conveying roller and the slitting roller are rotatably mounted on the outer frame and the inner frame, respectively. A cutting disc is fixedly mounted on one of the slitting rollers, and a cutting wheel is fixedly mounted on the other slitting roller. The multi-station winding device is mounted on the outer frame plate fixedly mounted on the outer frame and on the inner frame, and the multi-station winding device restricts the paper tube. The station motor is fixedly mounted on the bracket fixedly mounted on the inner frame, and the output end of the station motor is connected to the multi-station winding device.
[0007] Preferably, there are two slitting rollers, which are arranged vertically and horizontally. The upper slitting roller has several cutting blades fixedly installed horizontally, and the lower slitting roller has several cutting wheels fixedly installed horizontally. The cutting blades and cutting wheels are arranged correspondingly to each other.
[0008] Preferably, the outer surface of the cutting wheel is provided with a cutting groove corresponding to the cutting edge of the cutting disc, and the cutting disc and the cutting wheel are located on one side above the multi-station winding device.
[0009] Preferably, the multi-station winding device includes a station plate, a winding motor, a winding roller, a fixed cone, a locking cylinder, and a locking cone. The station plate is rotatably mounted on the inner frame and fixed to the output end of the station motor. The output end of the winding motor fixedly mounted on the station plate is fixed to one end of the winding roller that is rotatably mounted on it. A fixed cone is fixedly mounted on one end of each winding roller. The locking cylinder is fixedly mounted on the outer frame plate, and its output end is rotatably connected to the locking cone.
[0010] Preferably, at least two take-up rollers are installed on the work station plate, and a fixed cone is fixedly installed at one end of the take-up roller closest to the work station plate, and a locking cone is provided at the end of the take-up roller furthest from the work station plate.
[0011] Preferably, the outer surfaces of the locking cone and the fixed cone have the same taper, and the cone end face of the locking cone is provided with a groove, wherein the groove of the locking cone can be inserted into the end of the take-up roller away from the work station plate, and restrict and fix the paper tube between the locking cone and the fixed cone.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention utilizes two corresponding slitting rollers: an upper slitting roller with a cutting disc and a lower slitting roller with a cutting wheel. The cutting disc and cutting wheel correspond to each other, enabling efficient and precise slitting of self-adhesive labels. The outer surface of the cutting wheel has axially oriented cutting grooves corresponding to the cutting edge of the cutting disc, making the cutting process more stable, effectively improving slitting accuracy, and ensuring that the slitting labels meet standard dimensions, satisfying the diverse label size requirements of different customers.
[0014] This invention employs a multi-station design, with at least two take-up rollers installed on the station tray. A fixed cone is fixedly mounted at one end of the take-up roller closest to the station tray, while the other end is secured by a locking cylinder and the locking cone. During the winding process, once one take-up roller completes winding, the station motor drives the station tray to rotate, moving the next empty take-up roller to the working position, achieving uninterrupted winding and significantly improving production efficiency.
[0015] Meanwhile, in this invention, the outer surfaces of the locking cone and the fixing cone have the same taper, and the end face of the locking cone is provided with a groove, which can firmly restrict and fix the paper tube between the two, ensuring the stability of the paper tube during the winding process and making the label winding more neat.

[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] This utility model provides a slitting device for producing self-adhesive labels, including a conveying roller 1, a slitting roller 2, an outer frame 3, an inner frame 4, an outer frame plate 5, a multi-station winding device 6, a paper tube 7, a bracket 8, a station motor 9, a cutting disc 10, and a cutting wheel 11. The conveying roller 1 and the slitting roller 2 are rotatably mounted on the outer frame 3 and the inner frame 4, respectively. A cutting disc 10 is fixedly mounted on one of the slitting rollers 2, and a cutting wheel 11 is fixedly mounted on the other slitting roller 2. The multi-station winding device 6 is mounted on the outer frame plate 5 fixedly mounted on the outer frame 3 and on the inner frame 4, and the paper tube 7 is constrained on the multi-station winding device 6. The station motor 9 is fixedly mounted on the bracket 8 fixedly mounted on the inner frame 4, and the output end of the station motor 9 is connected to the multi-station winding device 6.
[0026] Furthermore, two slitting rollers 2 are provided, made of high-strength alloy steel, possessing excellent wear resistance and rigidity, and maintaining stable structural performance under long-term high-speed operation. The two slitting rollers 2 are arranged vertically and are rotatably mounted in bearing seats of the outer frame 3 and the inner frame 4 via precision bearings. Several cutting discs 10 are horizontally fixedly mounted on the upper slitting roller 2 via key connections. The cutting discs 10 are made of high-speed steel, and the blades are precision ground. The spacing between adjacent cutting discs 10 is adjusted and fixed by spacers, which can accurately ensure the distance between the cutting discs 10. Several cutting wheels 11 are also horizontally fixedly mounted on the lower slitting roller 2 via key connections. The cutting wheels 11 are made of alloy tool steel, quenched, and have high surface hardness and good wear resistance. The cutting discs 10 and cutting wheels 11 are vertically aligned to ensure that the cutting discs 10 can accurately act on the cutting wheels 11.
[0027] Furthermore, the outer surface of the cutting wheel 11 is axially provided with a cutting groove corresponding to the blade of the cutting disc 10. The width of the cutting groove is slightly larger than the thickness of the blade of the cutting disc 10, and the depth is 2-3mm. This design allows the blade of the cutting disc 10 to completely enter the cutting groove during the cutting process, avoiding contact between the blade and the non-cutting parts of the cutting wheel 11, thus preventing wear. It also effectively prevents the self-adhesive label material from bouncing or shifting during cutting, ensuring cutting stability. The cutting disc 10 and the cutting wheel 11 are located on one side above the multi-station winding device 6.
[0028] Furthermore, the multi-station take-up device 6 includes a station plate 61, a take-up motor 62, a take-up roller 63, a fixed cone 64, a locking cylinder 65, and a locking cone 66. The station plate 61 is made of cast iron and is rotatably mounted on a bearing seat on the inner frame 4 via precision bearings. It is fixed to the output end of the station motor 9 via a coupling. The station motor 9 is a servo motor, which can precisely control the rotation angle of the station plate 61. The take-up motor 62 is bolted to the station plate 61. The take-up motor 62 is a geared motor, and its output end is fixed to one end of the take-up roller 63, which is rotatably mounted in the bearing seat of the station plate 61, via a coupling. The take-up roller 63 is made of seamless steel pipe with a chrome-plated surface, making it rust-proof and smooth. Each take-up roller 63 has a fixed cone 64 welded to one end near the work station plate 61, and the surface is polished. The locking cylinder 65 is fixed to the outer frame plate 5 by bolts. The locking cylinder 65 is a pneumatic cylinder, and its output end is rotatably connected to the locking cone 66 through a bearing to ensure that the locking cone 66 can rotate together with the take-up roller 63.
[0029] Furthermore, at least two take-up rollers 63 are installed on the workstation plate 61. The take-up rollers 63 are evenly distributed circumferentially on the workstation plate 61, and the included angle between adjacent take-up rollers 63 is equal. This layout ensures that the take-up rollers 63 can accurately switch to the working position when the workstation plate 61 rotates. A fixed cone 64 is fixedly installed at one end of the take-up roller 63 closest to the workstation plate 61, and a locking cone 66 is provided at the end away from the workstation plate 61. The locking cone 66 and the fixed cone 64 are coaxially arranged to ensure that the paper tube 7 can be stably clamped between them.
[0030] Furthermore, the outer surfaces of the locking cone 66 and the fixed cone 64 have the same taper, both at 1:5. This taper design ensures that the paper tube 7 is subjected to uniform force when clamped, preventing deformation. The locking cone 66 has a groove on its cone end face, with a depth of 3-5mm and a width of 8-10mm. The groove of the locking cone 66 can be inserted into the end of the winding roller 63 away from the station plate 61 and close to the paper tube 7 sleeved on the winding roller 63, thereby restricting and fixing the paper tube 7 between the locking cone 66 and the fixed cone 64, ensuring that the paper tube 7 will not move axially or rotate circumferentially during the winding process.
[0031] The working principle is as follows: First, the self-adhesive roll to be slit is installed on the unwinding frame. One end of the self-adhesive roll passes through the conveyor roller 1 and the two corresponding slitting rollers 2 and is then fixed to the paper tube 7. The winding motor 62 is started, and the winding motor 62 drives the winding roller 63 to rotate. Under the action of the winding tension, the conveyor roller 1 starts to rotate, conveying the self-adhesive roll towards the slitting roller 2. At the same time, the unwinding frame rotates synchronously to unwind.
[0032] At this time, the upper and lower slitting rollers 2 rotate synchronously. The cutting disc 10 on the upper slitting roller 2 and the cutting wheel 11 on the lower slitting roller 2 cooperate with each other. When the self-adhesive material passes between the two, the blade of the cutting disc 10 is precisely embedded in the cutting groove of the cutting wheel 11 to slit the material. The cutting groove can effectively limit the displacement of the material during cutting and ensure the stability of the slitting process.
[0033] After being cut, the self-adhesive labels move towards the multi-station rewinder 6 under the continuous action of the winding tension. Since the cutting disc 10 and the cutting wheel 11 are located on the side above the multi-station rewinder 6, the cut labels can directly enter the winding area and gradually wrap around the paper tube 7 clamped by the fixed cone 64 and the locking cone 66.
[0034] When the paper tube 7 is fully wound, the winding motor 62 stops working, the locking cylinder 65 drives the locking cone 66 to retract, disengage from the winding roller 63, and release the fixation on the paper tube 7. The station motor 9 drives the station disk 61 to rotate, and rotates the next winding roller 63 with the new paper tube 7 to the working position. The locking cylinder 65 pushes the locking cone 66 forward to cooperate with the winding roller 63. At this time, the paper tube 7 can be manually straightened to keep it in a horizontal state, and the new paper tube 7 is clamped between the fixed cone 64 and the locking cone 66. Then, the cut label end is fixed to the new paper tube 7, and the winding motor 62 is started to continue winding, realizing uninterrupted cutting operation.
[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
