Description

Technical Field

[0001] The utility model relates to the technical field of plaster processing equipment, in particular to a device for punching and slitting plasters. Background Technique

[0002] The plaster is a kind of traditional Chinese medicine for external use. In ancient times, it was called thin paste. It is made by boiling vegetable oil or animal oil with medicine into a gelatinous substance and applying it on one side of cloth, paper or leather. During the production process of plasters, a slitter is used to cut them into single-piece structures. For the existing plaster slitters on the market, the needle roller for punching micro-holes needs to be inserted with needles on a needle inserting machine. Therefore, the diameter specifications generally need to match the needle inserting equipment and cannot be made according to the designed diameter. This results in the needle roller produced always being slightly larger in diameter than the front-end slitting roller. At the same speed, the length of the plaster line pulled by the needle roller with a slightly larger diameter is longer than that pulled by the slitting roller. If there is no tension compensation mechanism between the punching micro-hole station and the slitting station, the excess plaster will sag and lose tension, resulting in deviation of the traction at the slitting station. The current tension compensation mechanism of the equipment is a gravity roller, which uses gravity to compensate for tension. However, when reaching the compensation limit, it is necessary to stop the machine, manually tighten the plaster, and then restart the machine, which affects its processing efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a device for punching and slitting plasters to solve the technical problems in the background technique.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0005] A device for punching and slitting plasters, including a workbench, a needle punching mechanism, a slitting mechanism and a driving mechanism installed on the workbench. The needle punching mechanism and the slitting mechanism are powered by the driving mechanism. The needle punching mechanism is arranged on the front side of the slitting mechanism. The needle punching mechanism includes a first mounting frame and a first transmission shaft installed on the first mounting frame. The slitting mechanism includes a second mounting frame and a second transmission shaft installed on the second mounting frame. The driving mechanism includes a motor, a first synchronous pulley and a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are respectively installed on the first transmission shaft and the second transmission shaft. An electromagnetic clutch is also installed on the second transmission shaft, and the second synchronous pulley is installed on the electromagnetic clutch. The motor is drivingly installed with the second transmission shaft. The first synchronous pulley and the second synchronous pulley are driven by a belt, and the electromagnetic clutch is used to control the engagement or separation of the power between the first transmission shaft and the second transmission shaft. A gravity roller is also slidably installed on the front side of the second mounting frame, and a photoelectric sensor is arranged below the gravity roller.

[0006] Sliders are respectively installed on the left and right sides of the gravity roller, and slide rails are correspondingly installed on the second mounting frame along the vertical direction, and the sliders slide on the slide rails.

[0007] Inside the first mounting bracket, from top to bottom, there are a needle roller, a first pressure roller, and a first transmission shaft in sequence. The needle roller, the first pressure roller, and the first transmission shaft are respectively driven by meshing through first gears.

[0008] A guide roller is rotatably mounted on the front side or / and the rear side of the first mounting bracket. The guide roller is in front of or / and behind the first pressure roller and is arranged parallel to the first pressure roller.

[0009] Inside the second mounting bracket, from top to bottom, there are a knife roller, a second pressure roller, and a second transmission shaft in sequence. The knife roller, the second pressure roller, and the second transmission shaft are respectively driven by meshing through second gears.

[0010] Compared with the prior art, a device for punching and slitting plasters provided by the present utility model controls the power transmission between two mechanisms by using an electromagnetic clutch between the acupuncture mechanism and the slitting mechanism. The gravity roller is responsible for compensating the tension of the plaster tape in real time. When the gravity roller sags to near the limit position, the photoelectric inductor detects the signal. At this time, it feeds back to the PLC, and the PLC cuts off the power supply of the electromagnetic clutch. Thus, the power between the first synchronous pulley and the second synchronous pulley is cut off, and the needle roller stops working randomly, while the second transmission shaft continues to work. Therefore, the gravity roller will lift. After reaching a certain height, the photoelectric inductor cannot detect the signal, so the PLC continues to supply power to the electromagnetic clutch, and the power transmission between the first synchronous pulley and the second synchronous pulley is connected again, and the needle roller continues to work. Repeating like this, there is no need for shutdown operation, thereby realizing continuous tension compensation during the conveying process of the plaster, effectively improving the production efficiency of the plaster and ensuring the stability of the slitting quality of the plaster.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0014] Specific Embodiment 1: Please refer to Figure 1 and Figure 2, A device for puncturing and slitting plasters in this embodiment includes a workbench 1, a needle-punching mechanism 2, a slitting mechanism 3, and a driving mechanism 4 installed on the workbench 1. The needle-punching mechanism 2 and the slitting mechanism 3 are powered by the driving mechanism 4. The needle-punching mechanism 2 is arranged on the front side of the slitting mechanism 3. The needle-punching mechanism 2 includes a first mounting frame 201 fixed on the workbench 1. Inside the first mounting frame 201, from top to bottom are a needle roller 202, a first pressure roller 203, and a first transmission shaft 204. The needle roller 202, the first pressure roller 203, and the first transmission shaft 204 are respectively driven by meshing through a first gear 206. A guide roller 205 is rotatably installed on the front side and / or the rear side of the first mounting frame 201. In this embodiment, guide rollers 205 are installed on both the front side and the rear side of the first mounting frame 201. The guide rollers 205 are arranged on the front and rear sides of the first pressure roller 203 and are parallel to the first pressure roller 203.

[0015] The slitting mechanism 3 includes a second mounting frame 301 fixed on the workbench 1. Inside the second mounting frame 301, from top to bottom are a knife roller 302, a second pressure roller 303, and a second transmission shaft 304. The knife roller 302, the second pressure roller 303, and the second transmission shaft 304 are respectively driven by meshing through a second gear 308.

[0016] The driving mechanism 4 includes a motor 401, a first synchronous pulley 402, and a second synchronous pulley 403. The first synchronous pulley 402 and the second synchronous pulley 403 are respectively installed on the first transmission shaft 204 and the second transmission shaft 304. An electromagnetic clutch 404 is also installed on the second transmission shaft 304. The second synchronous pulley 403 is installed on the electromagnetic clutch 404. The motor 401 is drivingly installed with the second transmission shaft 304. The first synchronous pulley 402 and the second synchronous pulley 403 are driven by a belt 405. The engagement or separation of the power between the first transmission shaft 204 and the second transmission shaft 304 is controlled by the electromagnetic clutch 404.

[0017] A gravity roller 305 is also slidably installed on the front side of the second mounting frame 301. Sliders 306 are respectively installed on the left and right sides of the gravity roller 305. Slide rails 307 are correspondingly installed on the second mounting frame 301 along the vertical direction. The sliders 306 slide on the slide rails 307. A photoelectric sensor 5 is arranged below the gravity roller 305. The photoelectric sensor 5 is fixed on the workbench 1.

[0018] After startup, the motor 401 provides power, the second transmission shaft 304 rotates, drives the cutter roller 302 through the second gear to complete the shape cutting of the plaster, drives the first synchronous pulley 402 to rotate through the second synchronous pulley 403, the first synchronous pulley 402 transmits the power to the first transmission shaft 204, and the power from the first transmission shaft 204 is transmitted to the needle roller 202 through the first gear 206. The needle roller 202 punches micro-holes in the plaster. The gravity roller 305 is responsible for compensating the tension of the plaster tape in real time. When the gravity roller 305 droops to near the limit position, the photoelectric inductor 5 detects the signal, and at this time, it feeds back to the PLC. The PLC cuts off the power supply of the electromagnetic clutch 404, so the power between the first synchronous pulley 402 and the second synchronous pulley 403 is cut off, and the needle roller 202 stops working randomly, while the second transmission shaft 304 continues to work. Therefore, the gravity roller 305 will lift. After reaching a certain height, the photoelectric inductor 5 cannot detect the signal, so the PLC continues to supply power to the electromagnetic clutch 404, and the power transmission between the first synchronous pulley 402 and the second synchronous pulley 403 is connected again, and the needle roller 202 continues to work. This repeats without the need for shutdown operation.

[0019] Compared with the prior art, a device for plaster punching and cutting provided by the present utility model controls the power transmission between two mechanisms by using an electromagnetic clutch between the acupuncture mechanism and the cutting mechanism. The gravity roller is responsible for compensating the tension of the plaster tape in real time. When the gravity roller droops to near the limit position, the needle roller stops working randomly, while the second transmission shaft continues to work. The gravity roller will lift. After reaching a certain height, the photoelectric inductor cannot detect the signal, so the PLC continues to supply power to the electromagnetic clutch, and the power transmission between the first synchronous pulley and the second synchronous pulley is connected again, and the needle roller continues to work. Thus, continuous tension compensation during the conveying process of the plaster is realized, effectively improving the production efficiency of the plaster and ensuring the stability of the plaster cutting quality.
