Description

Technical Field

[0001] This utility model relates to the field of hydrogel patch production technology, and specifically discloses a cutting device for hydrogel patch production. Background Technology

[0002] Hydrogel patches are medical dressings or functional patches made with hydrogel as the core material. They have unique physical and chemical properties and are widely used in medical, cosmetic and other fields. During the production process, hydrogel patch raw materials need to be cut by a cutting device.

[0003] Existing cutting devices for hydrogel patch production mostly use rotating rollers with cutting blades on the outer wall to cut the hydrogel patch raw materials. After cutting, some hydrogel patches remain in the holes left by the cut raw materials, while others are adsorbed onto the cutting blades of the rotating rollers. Subsequently, the machine needs to be stopped and manually removed, which not only affects the cutting efficiency of hydrogel patches, but also increases the labor burden of workers and is inconvenient to use. Utility Model Content

[0004] This invention proposes a cutting device for hydrogel patch production, which prevents the cut hydrogel patches from remaining in the holes after the raw material is cut or adhering to the cutting blade of the rotating roller. It eliminates the need for subsequent machine shutdown and manual cleaning, avoids affecting the cutting efficiency of hydrogel patches, effectively reduces the labor burden of workers, and is convenient to use.

[0005] This utility model is implemented as follows: a cutting device for producing hydrogel patches includes a base, and a cutting mechanism is provided above the base. The cutting mechanism includes a cutting table fixedly connected to the upper surface of the base. The upper surface of the cutting table has a through-hole for feeding. A top plate is provided above the base. A cutting block matching the feeding hole is fixedly connected to the lower surface of the top plate. The edge of the lower surface of the cutting block is provided with a cutting blade structure. A positioning mechanism is provided on the outer wall of the cutting block. An anti-adsorption mechanism is provided inside the cutting block. The anti-adsorption mechanism includes a cavity inside the cutting block, and the lower end face of the cutting block has multiple evenly distributed air vents.

[0006] In a preferred embodiment of the cutting device for producing hydrogel patches according to this utility model, the positioning mechanism includes a mounting plate fixedly connected to the outer wall of the cutting block, an annular plate disposed below the mounting plate, and a plurality of evenly distributed sliding rods fixedly connected to the upper end face of the annular plate. The upper end faces of the plurality of sliding rods extend above the mounting plate, the sliding rods are slidably connected to the mounting plate, and a spring sleeved on the outer wall of the sliding rod is fixedly connected between the mounting plate and the annular plate.

[0007] As a preferred embodiment of the cutting device for producing hydrogel patches according to this utility model, the upper end face of the base is equipped with unwinding rollers and rewinding rollers distributed on the left and right, and the upper end of the outer wall of the unwinding rollers and rewinding rollers is flush with the upper end face of the cutting table.

[0008] As a preferred embodiment of the cutting device for hydrogel patch production according to this utility model, a plurality of evenly distributed electric telescopic rods are installed between the base and the top plate.

[0009] As a preferred embodiment of the cutting device for producing hydrogel patches according to this utility model, a high-pressure fan is installed on the upper end face of the top plate, and the air outlet of the high-pressure fan is connected to the cavity.

[0010] In a preferred embodiment of the cutting device for producing hydrogel patches according to this utility model, the upper ends of the plurality of slide bars are all fixedly connected with blocks.

[0011] The beneficial effects of this utility model are: The hydrogel patch material is moved by the interaction between the unwinding roller and the rewinding roller. The hydrogel patch material is cut by the interaction between the cutting block and the feeding hole.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0016] Please see Figure 1-3 A cutting device for producing hydrogel patches includes a base 1, and a cutting mechanism is provided above the base 1. The cutting mechanism includes a cutting table 2 fixedly connected to the upper surface of the base 1. A material feeding hole 3 is provided through the upper surface of the cutting table 2. A top plate 4 is provided above the base 1. A cutting block 5 matching the material feeding hole 3 is fixedly connected to the lower surface of the top plate 4. A cutting blade structure is provided at the edge of the lower surface of the cutting block 5. A positioning mechanism is provided on the outer wall of the cutting block 5. An anti-adsorption mechanism is provided inside the cutting block 5. The anti-adsorption mechanism includes a cavity 6 inside the cutting block 5, and multiple evenly distributed air vents 7 are provided through the lower end face of the cutting block 5.

[0017] In this embodiment: During use, the hydrogel patch material is unwound by the unwinding roller 12, and one end of the hydrogel patch material is fixed to the take-up roller 13. The take-up roller 13 collects the cut hydrogel patch waste. Then, the unwinding roller 12 and the take-up roller 13 rotate intermittently, thereby driving the hydrogel patch material to move intermittently. When the hydrogel patch material stops, multiple electric telescopic rods 14 drive the top plate 4 to move downward. The top plate 4 drives the cutting block 5 to move downward, so that the cutting block 5 is close to the hydrogel patch material. The cutting block 5 and the feeding hole 3 cooperate to cut the hydrogel patch material. Before cutting, the positioning mechanism first contacts the hydrogel patch material and positions it to prevent misalignment during the cutting process. Then, the cut hydrogel patch is pushed into the feeding hole 3 by the cutting block 5. At the same time, high-pressure air is delivered into the cavity 6 by the high-pressure blower 15 and then discharged through multiple air outlets 7. The high-pressure air blows the hydrogel patch downwards, preventing it from staying in the holes after cutting or adhering to the lower end of the cutting block 5. This eliminates the need for manual cleaning after machine shutdown, avoiding affecting the cutting efficiency of the hydrogel patch, effectively reducing the workload of workers, and making it convenient to use.

[0018] As a technical optimization of this utility model, the positioning mechanism includes a mounting plate 8 fixedly connected to the outer wall of the cutting block 5, an annular plate 9 is provided below the mounting plate 8, and a plurality of evenly distributed sliding rods 10 are fixedly connected to the upper end face of the annular plate 9. The upper end faces of the plurality of sliding rods 10 all extend to the top of the mounting plate 8, and the sliding rods 10 are slidably connected to the mounting plate 8. A spring 11 sleeved on the outer wall of the sliding rod 10 is fixedly connected between the mounting plate 8 and the annular plate 9.

[0019] In this embodiment: when the cutting block 5 moves downward, the annular plate 9 first comes into contact with the hydrogel adhesive material, and the annular plate 9 squeezes and positions the hydrogel adhesive material. Then the cutting block 5 continues to move downward, so that the cutting block 5 enters the feeding hole 3, and the hydrogel adhesive material is cut by the mutual cooperation between the cutting block 5 and the feeding hole 3. At the same time, the annular plate 9 pushes multiple sliding rods 10 to slide in the mounting plate 8 and squeezes multiple springs 11 to contract, so that multiple springs 11 generate a rebound force. The rebound force of multiple springs 11 pushes the annular plate 9 to continue to act downward. During the cutting process, the hydrogel adhesive material is continuously squeezed and positioned.

[0020] As a technical optimization of this utility model, the upper end face of the base 1 is equipped with a left-right distributed unwinding roller 12 and a right-right winding roller 13, and the upper end of the outer wall of the unwinding roller 12 and the right-right winding roller 13 is flush with the upper end face of the cutting table 2.

[0021] In this embodiment: the hydrogel patch material is unwound by the unwinding roller 12, and the hydrogel patch waste material after cutting is collected by the take-up roller 13 (the unwinding roller 12 and the take-up roller 13 are detachable structures and can be replaced. This is a well-known and mature existing technology, and its components and working principle will not be described in detail here).

[0022] As a technical optimization of this utility model, a plurality of evenly distributed electric telescopic rods 14 are installed between the base 1 and the top plate 4.

[0023] In this embodiment, the top plate 4 can be moved by multiple electric telescopic rods 14.

[0024] As a technical optimization of this utility model, a high-pressure blower 15 is installed on the upper surface of the top plate 4, and the air outlet of the high-pressure blower 15 is connected to the cavity 6.

[0025] In this embodiment, high-pressure air can be delivered into the cavity 6 by the high-pressure blower 15.

[0026] As a technical optimization of this utility model, a stop block 16 is fixedly connected to the upper end of each of the multiple sliding rods 10.

[0027] In this embodiment, the stop block 16 can limit the slide rod 10 to prevent it from detaching from the mounting plate 8.

[0028] The working principle and usage process of this utility model are as follows: In use, the unwinding roller 12 unwinds the hydrogel patch material, and one end of the material is fixed to the take-up roller 13. The take-up roller 13 collects the cut hydrogel patch waste. The unwinding roller 12 and take-up roller 13 rotate intermittently, causing the hydrogel patch material to move intermittently. When the hydrogel patch material stops, multiple electric telescopic rods 14 move the top plate 4 downwards. The top plate 4 then moves the cutting block 5 downwards, bringing it close to the hydrogel patch material. The cutting block 5 cuts the hydrogel patch material through its interaction with the feeding hole 3. Before cutting, the positioning mechanism first engages with the hydrogel patch material... The adhesive material is brought into contact with the hydrogel adhesive material and positioned to prevent the hydrogel adhesive material from shifting during the cutting process. Specifically, when the cutting block 5 moves downward, the annular plate 9 first comes into contact with the hydrogel adhesive material and squeezes and positions the hydrogel adhesive material through the annular plate 9. Then the cutting block 5 continues to move downward, so that the cutting block 5 enters the feeding hole 3, and the hydrogel adhesive material is cut through the mutual cooperation between the cutting block 5 and the feeding hole 3. At the same time, the annular plate 9 pushes multiple sliding rods 10 to slide in the mounting plate 8 and squeezes multiple springs 11 to contract, so that multiple springs 11 generate a rebound force. Through the rebound force of multiple springs 11, the annular plate 9 continues to act downward, and the hydrogel adhesive material is continuously squeezed and positioned during the cutting process. Then, the cut hydrogel patch is pushed into the feeding hole 3 by the cutting block 5. At the same time, high-pressure air is delivered into the cavity 6 by the high-pressure blower 15 and then discharged through multiple air outlets 7. The high-pressure air blows the hydrogel patch downward to prevent the cut hydrogel patch from staying in the holes after the raw material is cut or adhering to the lower end face of the cutting block 5.
