Description

Technical Field

[0001] The invention belongs to the field of plaster manufacturing, and in particular relates to a slitting device in the production of plasters. Background Art

[0002] Plasters are commonly used plasters that are applied to the affected parts of the body. Plasters have become a frequently used medicine patch in daily life and are in great demand, so large-scale production has been achieved in factories. The production process of plasters is usually glue making, coating, drying and cooling, molding, and packaging. In the molding process, the rolled plaster is usually placed on a slitting mechanism to be cut into small plaster patches. However, during the slitting process, the plaster has a large viscosity and the slitting mechanism will heat up after long-term operation. This causes the plaster to stick to the knife during slitting, reducing the smoothness of the blade and further making the slitting incomplete; and the existing slitting mechanism cannot quickly adjust the slitting gap according to the size of the plaster.

DETAILED DESCRIPTION

[0018] As shown in the accompanying drawings, one embodiment of the present invention is a slitting device used in the production of plasters, including a roller 1, the roller 1 passes through a plurality of circular cutters 3 and an adjusting shaft 2, and the adjusting shaft 2 is located between adjacent circular cutters 3 and is staggered with the circular cutters 3 on the roller, and the adjusting shaft 2 and the circular cutters 3 are detachably connected to the roller 1.

[0019] The adjusting shaft 2 is a hollow cylindrical structure made of metal, specifically including a semi-cylinder A 7 and a semi-cylinder B 8. The semi-cylinder A 7 and the semi-cylinder B 8 are connected together by a hinge column 9. The outer side surfaces of the free ends of the semi-cylinder A 7 and the semi-cylinder B 8 are provided with connecting plates 10. A threaded through hole 11 passes through the middle of the connecting plate 10. The outer side surfaces of the semi-cylinder A 7 and the semi-cylinder B 8 are fixed together by nuts.

[0020] Further, the semi-cylinder A 7 and the semi-cylinder B 8 are provided with a plurality of through holes 13 penetrating the inner side and the outer side, the inner side of the free end of the semi-cylinder A 7 and the semi-cylinder B 8 are provided with semi-cylindrical protrusions 12 of the same size, and the semi-cylindrical protrusions and the through holes are arranged on the same horizontal plane, and the two semi-cylindrical protrusions 12 cooperate to form a cylindrical protrusion, and a card slot 15 is provided in the middle position of the inner side of the semi-cylinder A 7 and the semi-cylinder B 8 from top to bottom in the vertical direction, and a groove 14 is provided on the top and bottom surfaces of the adjustment shaft 2, and a non-slip rubber gasket is detachably installed in the groove 14, and the thickness of the rubber non-slip gasket can be adjusted according to the size of the gap. The length of the adjustment shaft is set to 50-120mm according to the width and length of the commonly used plaster patch. During use, the length of the adjustment shaft can be selected according to the required width of the specific plaster patch.

[0021] The roller shaft 1 is an integrally formed hollow cylinder with a plurality of through holes on the surface connected to the interior. The through holes on the surface of the roller shaft 1 coincide with the through holes on the adjusting shaft 2. A cylindrical positioning groove 17 is formed on the surface of the roller shaft 1. The positioning groove 17 coincides with the cylindrical protrusion 12 on the adjusting shaft 2, and the positioning groove and the cylindrical protrusion are interference fit. The number of positioning grooves is greater than the number of adjusting shafts, so it can adapt to the application of adjusting shafts of different sizes.

[0022] The surface of the roller shaft 1 is provided with two semi-cylindrical clamping strips 16, which cooperate with the clamping grooves 15 in the semi-cylinder A 7 and the semi-cylinder B 8. At the same time, the circular cutter is also provided with a groove to cooperate with the clamping strips.

[0023] A coaxial bearing 4 is fixed at one end of the roller shaft 1 , and the outer ring of the bearing is fixed together with the roller shaft 1 . A circular air duct 5 is fixed to the inner ring of the bearing 4 , and the circular air duct 5 is connected to a cooling fan 6 .

[0024] During use of the present invention, the length of the adjustment shaft can be selected according to the required width of the plaster patch, the required number of circular cutters is calculated and the circular cutters are inserted into the roller shaft, and the clamping strip on the roller shaft cooperates with the clamping groove on the circular cutter to prevent the circular cutter from rolling on the roller shaft.

[0025] Fix the rubber anti-skid pads in the grooves on both sides of the adjusting shaft. The setting of the rubber anti-skid pads can, on the one hand, fix the circular cutter, and on the other hand, reduce the vibration of the circular cutter during the slitting process. The semi-cylinder A and semi-cylinder B of the adjusting shaft are respectively clamped on the clamping strips of the roller shaft. Close the adjusting block so that the two semi-cylindrical protrusions are inserted into the positioning grooves, and then use positioning pins or screws to insert into the threaded through holes for fastening, so as to fix it in the horizontal and vertical directions. If there is a gap between the adjusting shaft and the circular cutters on both sides, the thickness of the rubber anti-skid pad can be appropriately changed for adjustment.

[0026] During the slitting process, the cold air produced by the air cooler is passed into the roller shaft through the circular air duct, and blown to the circular cutters on both sides through the through holes on the roller shaft and the adjustment shaft, which plays a role in reducing the temperature of the circular cutters, so that the cutters will not melt the plaster due to the temperature increase and cause the cutters to stick, thereby improving the success rate of slitting. When changing the size of the plaster, it is necessary to adjust the position of the circular cutter, and there is no need to remove all the circular cutters. The adjustment shaft can be removed, and then the size of the plaster cut by the circular cutter can be changed by adding or removing circular cutters and adjustment shafts.
