Description

Technical Field

[0001] This utility model relates to a processing equipment for applying adhesive patches, and more specifically to a cutting device for applying adhesive patches. Background Technology

[0002] In the existing dressing production process, the following process is usually adopted: a quantitative dressing (such as medicine, hydrogel, etc.) is continuously laid in piles on a complete long non-woven fabric substrate, and then covered with another long non-woven fabric to form a multi-layer composite tape.

[0003] To divide the composite tape into individual dressing products, current processes generally rely on mechanical cutting tools (such as cutting dies and rotary blades) to physically cut the tape. However, this method has significant drawbacks: when the cutting tool continuously cuts the nonwoven fabric and internal dressing (especially when the dressing has a certain degree of stickiness or hardness), the cutting edge is prone to wear, dulling, or even chipping, leading to problems such as reduced cutting quality (e.g., rough edges, dressing overflow under pressure) or incomplete cutting.

[0004] To ensure product consistency and pass rate, production equipment must be shut down periodically to replace or reflash cutting tools. This not only directly increases the cost of cutting tool consumables and maintenance workload, but also severely restricts the continuous operation efficiency of the production line, resulting in extended unnecessary downtime, increased manual intervention, and overall capacity loss. It is one of the key bottlenecks restricting the automation and efficiency improvement of this process. Utility Model Content

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example:

[0034] See Figure 1 This embodiment discloses a cutting device for applying a dressing, including a frame (not shown in the figure), a base plate 10, a rotor 20, a drive assembly 30, a telescopic assembly 40, and a heating wire 50. The base plate 10 is horizontally mounted on the frame and located in the lower half of the frame (relative to other components). The rotor 20 is rotatably mounted on the frame. The drive assembly 30 and the telescopic assembly 40 are directly mounted on the frame. The heating wire 50 is mounted on the telescopic assembly 40.

[0035] Specifically, the base plate 10 has a cutting groove 11 running through both sides. The rotor 20 can rotate intermittently on the frame, and the rotor 20 also has a through groove 21 running through both ends. During rotation, the rotor 20 stops rotating for a certain period of time each time the through groove 21 and the cutting groove 11 are in the same vertical direction. The drive assembly 30 is mainly used to drive the intermittent rotation of the rotor 20. The heating wire 50 is installed on the telescopic part of the telescopic assembly 40, and the heating wire 50 is arranged vertically. The heating wire 50 can move in the cutting groove 11 and the through groove 21 under the drive of the telescopic assembly 40.

[0036] In this embodiment, the multi-layer composite strip moves on the base plate 10, mainly through the pressing and driving of the rotor 20. When the rotor 20 rotates once, the cutting part of the multi-layer composite strip is exposed between the cutting groove 11 and the through groove 21. At this time, the telescopic component 40 drives the heating wire 50 to move once within the cutting groove 11 and the through groove 21, and uses the heat generated by the heating wire 50 to cut out individual patches.

[0037] In one specific embodiment:

[0038] The drive assembly 30 includes a gear 31, a motor 32, and a sector tooth 33. The gear 31 is coaxially mounted on the rotor 20, the motor 32 is fixedly mounted on the frame, and the sector tooth 33 is mounted on the output shaft of the motor 32.

[0039] During installation, the motor 32 drives the sector teeth 33 to rotate, and enables the sector teeth 33 to mesh with the gear 31.

[0040] Preferably, in order to control the rotational speed of the rotor 20, a speed reducer is installed between the output shaft of the motor 32 and the sector gear 33, which can also increase the output torque of the sector gear 33.

[0041] In this embodiment, during the rotation of the sector tooth 33, it can only mesh with the gear 31 for part of the time, so that the gear 31 can only rotate a certain angle, thereby realizing the intermittent rotation of the gear 31 and the rotor 20.

[0042] In another specific embodiment:

[0043] The pitch circle diameter of gear 31 is equal to the pitch circle diameter of sector tooth 33. Multiple through slots 21 are evenly distributed in the circumferential direction of rotor 20. The arc corresponding to sector tooth 33 is equal to the ratio of 360° to the number of through slots 21.

[0044] Specifically, in the initial state, one through slot 21 on the rotor 20 matches the cutting slot 11. After the rotor 20 rotates once, the next through slot 21 on the rotor 20 needs to match the cutting slot 11. Since all through slots 21 are evenly distributed on the rotor 20, the angle of rotation of the rotor 20 each time should be the ratio of 360° to the number of through slots 21, that is, the arc corresponding to the tooth structure on the sector tooth 33 should be this ratio. For example Figure 1 As shown, there are 4 through slots 21, so the angle of rotation of rotor 20 should be 90° each time, and the arc of the upper tooth structure of sector tooth 33 should also be 90°.

[0045] In another specific embodiment:

[0046] The rotor 20 has multiple embedding grooves 22 on its circumferential surface. There is an embedding groove 22 between two adjacent through grooves 21. In this embodiment, since the dressing is continuously laid on a complete long nonwoven fabric substrate and covers another long nonwoven fabric substrate, the multilayer composite strip has a raised structure at multiple positions with equal spacing.

[0047] Therefore, by setting an embedding groove 22 on the rotor 20, when the rotor 20 drives the multi-layer composite strip, the raised dressing can just enter the embedding groove 22, thereby avoiding the excipient being squeezed. This not only protects the integrity of the cut dressing, but also uses the pushing effect of the inner wall of the embedding groove 22 on the raised excipient to drive the multi-layer composite strip to move on the base plate 10.

[0048] In another specific embodiment:

[0049] The telescopic assembly 40 includes two cylinders, which are mounted parallel to each other on the frame. The piston rods of the two cylinders are connected to both ends of the heating wire 50, and the piston rods of the cylinders constitute the telescopic portion of the telescopic assembly 40. In this embodiment, the two ends of the heating wire 50 are moved synchronously by the two cylinders.

[0050] In another specific embodiment:

[0051] A wire 51 is connected to each end of the heating wire 50. One end of the wire 51 is located on the cylinder, and this end of the wire 51 is a spiral spring wire 52. Since the heating wire 50 requires a continuous power supply, the spring wire 52 is provided so that the power supply cable of the heating wire 50 can be freely extended and retracted during the process of the cylinder driving the heating wire 50 to move.

[0052] In another specific embodiment:

[0053] The base plate 10 is also provided with a drive groove 12 perpendicular to the cutting groove 11. The drive groove 12 is provided with a conveyor belt 13, which assists in the movement of the multi-layer composite strip.

[0054] Preferably, the surface of the conveyor belt 13 is provided with a plurality of drive teeth 14. By providing drive teeth 14, slippage between the surface of the conveyor belt 13 and the multi-layer composite belt material is avoided.

[0055] The drive slot 12 is located on one side of the cutting slot 11, and the base plate 10 on the other side of the cutting slot 11 is a suspended structure. By setting one end of the base plate 10 as a suspended structure, the dressing can automatically fall into the collection device after cutting.

[0056] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
