[0002] Plasters are a common topical preparation made by mixing drugs with a base and then applying the mixture to a backing material. They exert local or systemic therapeutic effects through skin penetration and are widely used in the fields of pain relief, anti-inflammation, and blood circulation promotion. Cutting devices can cut the coated plaster rolls into suitable shapes for convenient subsequent use.
[0003] The existing plaster production cutting equipment still has the following shortcomings: the cutting effect of the existing plaster production cutting equipment is not good. The plaster roll is pulled and cut at the same time. The vibration of the plaster during the pulling process may cause uneven contact between the cutting blade and the plaster, resulting in defects such as burrs, rough edges or tears at the cutting edge, which affects the appearance quality of the plaster. Utility Model Content

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] like Figures 1-4 As shown, this utility model provides a technical solution:
[0021] A plaster production and cutting device includes a base plate 1. A support frame 2 and a pair of support plates 3 are fixedly connected to the top of the base plate 1. A guide shaft is rotatably connected to the support frame 2, and a rotating block 4 is coaxially fixedly connected to one end of the guide shaft. The rotating block 4 has multiple limiting elongated grooves and multiple limiting arc grooves. A rotating shaft is rotatably connected to each of the pair of support plates 3. A servo motor 5 is fixedly connected to one side of one support plate 3, and the output end of the servo motor 5 is coaxially fixedly connected to the rotating shaft. A cam 6 is coaxially fixedly connected to the rotating shaft, and a pulley 7 is coaxially fixedly connected to one end of the rotating shaft. A transmission assembly is provided on one side of the other support plate 3. A cutting assembly and a leveling assembly are respectively provided between the pair of support plates 3. An anti-adhesive layer is attached to the plaster roll. The flattening component can press down the adhesive strip, keeping it flat as it is pulled, improving the cutting effect. It can also effectively smooth out any wrinkles and air bubbles that may exist between the adhesive strip and the anti-adhesive layer, ensuring a tight bond. One end of the adhesive strip is wound around the guide shaft. When the servo motor 5 is started, the output of the servo motor 5 drives the cam 6 and the pulley 7 to rotate through the rotating shaft. The pulley 7 drives the rotating block 4 to rotate intermittently through the transmission component. The rotating block 4 drives the guide shaft to intermittently pull the adhesive strip. During the pulling, the cutting component does not work. When it stops, the cam 6 drives the cutting component to work, which can prevent the position of the adhesive strip from shifting during movement, ensuring that the cut is flat and the size is accurate, reducing burrs and defects, and improving the product qualification rate.
[0022] The transmission assembly includes a second rotating shaft, which is rotatably connected to one side of the support plate 3. One end of the second rotating shaft is coaxially and fixedly connected to a second pulley 8. A belt is fitted between the second pulley 8 and the first pulley 7. A crescent block 9 and a rotating rod 10 are fixedly connected to the side of the second pulley 8 away from the second rotating shaft. The crescent block 9 is adapted to a limiting arc groove, and the rotating rod 10 is adapted to a limiting long groove.
[0023] Belt pulley 7 drives belt pulley 8 to rotate. Belt pulley 8 drives crescent block 9 and rotating rod 10 to rotate together. Rotating rod 10 enters the limiting groove on rotating block 4, causing rotating block 4 to rotate. At this time, the outermost circumference of rotating block 4 rotates along the notch of crescent block 9. After rotating through a certain angle, rotating rod 10 disengages from the limiting groove, and rotating block 4 stops rotating, thus realizing the intermittent rotation of rotating block 4. Crescent block 9 just rotates into the limiting arc groove on rotating block 4, restricting the rotation of rotating block 4.
[0024] The cutting assembly includes a T-block 11, which is positioned between a pair of support plates 3. Connecting blocks 12 are fixedly connected to both sides of the T-block 11. Limiting rods 13 are slidably connected to the connecting blocks 12. Springs 14 are sleeved around the outer periphery of the limiting rods 13. A connecting frame 15 is fixedly connected to the limiting rods 13, with one side of the connecting frame 15 fixedly connected to the support plate 3. Multiple ring cutters 16 are fixedly connected to the bottom of the T-block 11, and a lower pressure plate is fixedly connected to one side of the T-block 11. 17. The protrusion of cam 6 rotates and presses down the lower pressure plate 17, which drives the T-block 11, connecting block 12 and ring cutter 16 to press down as a whole. The connecting block 12 slides down on the outer periphery of the limiting rod 13, and the spring 14 is compressed. The ring cutter 16 presses down to cut the adhesive strip. When the protrusion of cam 6 rotates and separates from the lower pressure plate 17, the spring 14 pushes the connecting block 12 to slide up on the outer periphery of the limiting rod 13, so that the T-block 11, lower pressure plate 17 and ring cutter 16 rise and reset as a whole.
[0025] The leveling component includes a connecting plate 18, which is fixedly connected between a pair of support plates 3. A pair of sliding rods 19 are slidably connected to the connecting plate 18. A crossbar 20 is fixedly connected to the top of each sliding rod 19, and a leveling strip 21 is fixedly connected to the bottom of each sliding rod 19. A second spring 22 is sleeved on the outer periphery of each sliding rod 19. When the crossbar 20 is lifted, the crossbar 20 drives the sliding rod 19 and the leveling strip 21 to rise together. The sliding rod 19 slides on the connecting plate 18, and the leveling strip 21 rises and squeezes the second spring 22. The adhesive strip passes through the leveling strip 21 and the placement plate 23. When the crossbar 20 is released, the second spring 22 pushes the leveling strip 21 to press the adhesive strip tightly.
[0026] A placement plate 23 is fixedly connected between a pair of support plates 3. The placement plate 23 has multiple through holes, each of which is adapted to the ring cutter 16. The adhesive strip moves on the upper surface of the placement plate 23, and the cut adhesive block falls through the through hole.
[0027] A limiting rod 24 is fixedly connected between a pair of support plates 3. The adhesive strip passes under the limiting rod 24. The limiting rod 24 can prevent the adhesive strip from lifting up due to the thickening of the waste roll on the guide shaft.
[0028] The working principle of this utility model is as follows:
[0029] The adhesive strip has an anti-adhesive layer attached. When the crossbar 20 is lifted, the crossbar 20 drives the sliding rod 19 and the flat strip 21 to rise together. The sliding rod 19 slides on the connecting plate 18, and the flat strip 21 rises and compresses the second spring 22. The adhesive strip first passes between the flat strip 21 and the placement plate 23, and then passes under the limiting rod 24. Finally, one end of the adhesive strip is wrapped around the guide shaft. At this time, the crossbar 20 is released, and the second spring 22 pushes the flat strip 21 to press the adhesive strip tightly. With the traction of the adhesive strip, the adhesive strip is kept flat, improving the cutting effect and effectively smoothing out any wrinkles and air bubbles that may exist between the adhesive strip and the anti-adhesive layer, so that the two are tightly bonded.
[0030] When the servo motor 5 is started, the output of the servo motor 5 drives the cam 6 and the pulley 7 to rotate through the first rotating shaft. The pulley 7 drives the second pulley 8 to rotate through the belt. The second pulley 8 drives the crescent block 9 and the rotating rod 10 to rotate together. The rotating rod 10 enters the limiting groove on the rotating block 4, driving the rotating block 4 to rotate. At this time, the outermost circumference of the rotating block 4 rotates along the notch of the crescent block 9. After rotating through a certain angle, the rotating rod 10 disengages from the limiting groove, and the rotating block 4 stops rotating, thus realizing the intermittent rotation of the rotating block 4. The crescent block 9 just rotates into the limiting arc groove on the rotating block 4, restricting the rotation of the rotating block 4. The rotating block 4 drives the guide shaft to intermittently pull the adhesive strip.
[0031] When traction stops, the protrusion of cam 6 rotates and presses down the pressure plate 17, causing the T-block 11, connecting block 12 and ring cutter 16 to press down as a whole. The connecting block 12 slides down on the outer periphery of the limit rod 13, and the spring 14 is compressed. The ring cutter 16 presses down to cut the adhesive strip. When the protrusion of cam 6 rotates and separates from the pressure plate 17, the spring 14 pushes the connecting block 12 to slide up on the outer periphery of the limit rod 13, so that the T-block 11, pressure plate 17 and ring cutter 16 rise and reset as a whole. At the same time, the rotating block 4 drives the guide shaft to pull the adhesive strip, which can prevent the position of the adhesive strip from shifting during movement, ensure that the cut is flat and the size is accurate, reduce burrs and defects, and improve the product qualification rate.
[0032] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
