Description

Technical Field

[0001] This utility model belongs to the field of medical catheter cutting technology, specifically relating to an automatic medical catheter cutting device. Background Technology

[0002] Medical catheters are devices used in medical procedures to help drain fluids, gases, or medications from the body. They are typically flexible, long, and thin tubular structures that can be inserted into various parts of the body. During the manufacturing process, automated cutting equipment is used to precisely cut medical catheters, ensuring that they meet required specifications and lengths during production, packaging, and use.

[0003] Existing cutting equipment has low precision in equidistant cutting when processing conduits, resulting in inconsistent conduit lengths. This affects subsequent assembly and use, and requires frequent adjustments by staff, increasing the risk of equipment failure and reducing the stability and long-term reliability of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an automatic medical catheter cutting device that can continuously cut catheters at equal intervals, reducing the time and cost of manual operation, as well as quality problems and defective products caused by size discrepancies.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An automatic medical catheter cutting device includes a cutting unit, a delivery port, and a conveyor belt. The delivery port is located at the front of the cutting unit. The conveyor belt is positioned at the front and rear of the cutting unit and extends through the delivery port. The cutting unit works in conjunction with the conveyor belt. An equidistant cutting mechanism is provided at the front of the cutting unit. The equidistant cutting mechanism includes: a servo motor, which is fixedly mounted at the rear of the cutting unit, with its output shaft extending to the front of the cutting unit; an output gear, which is fixedly connected to the output shaft at the front of the servo motor; a rotating gear, which meshes with the bottom of the output gear and is rotatably connected to the front of the cutting unit; and a rotating column. The rotating column is fixedly connected to the front side of the output gear and the rotating gear respectively; the limiting frame, both of which are fixedly connected to the front side of the cutting device, are located at the top and bottom of the conveying port; the blade holder, both of which are slidably connected to the inside of the two limiting frames respectively; the cutting shears, both of which are fixedly connected to the inside of the blade holder and arranged opposite to each other; the round shaft, both of which are fixedly connected to the front auxiliary rods of the two blade holders respectively, one end of each of the two auxiliary rods is connected to the front side of the cutting device through a rotating shaft, the other end of each of the two auxiliary rods is slidably connected to the surface of the two round shafts respectively, and the two auxiliary rods are slidably connected to the surface of the two rotating column respectively.

[0007] Preferably, both auxiliary rods have sliding grooves inside, and the rotating column and the round shaft are slidably connected inside the sliding grooves.

[0008] Preferably, both the rotating column and the circular shaft are fitted with limiting rings, and the limiting rings are located on the surface of the auxiliary rod.

[0009] Preferably, the surface of the conveyor belt is connected with pipe clamps, and there are several pipe clamps that are evenly distributed at equal intervals on the surface of the conveyor belt.

[0010] Preferably, a support plate is connected between the two conveyor belts, and a cutting groove is provided on the top of the support plate.

[0011] Preferably, a PLC controller is installed on the front side of the cutting device, and the PLC controller is electrically connected to the servo motor and the conveyor belt.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, when cutting the conduit, the conduit is first placed between the pipe clamps on the conveyor belt to limit its position. The conveyor belt then transports the conduit while a servo motor operates. The servo motor drives an output gear, which in turn drives a meshing rotating gear to rotate in the opposite direction. The simultaneous rotation of the rotating and output gears causes a rotating column to rotate. This rotating column slides inside the auxiliary rods, causing one end of each auxiliary rod to swing up and down around a pivot. When the two auxiliary rods swing up and down simultaneously, the blade holder and cutting shears move smoothly up and down within the limiting frame. When the two auxiliary rods move inward simultaneously, the blade holder and cutting shears move inward within the limiting frame, automatically cutting the conduit transported on the conveyor belt. As the output gear drives the meshing rotating gear to rotate continuously, the conduit on the conveyor belt is continuously cut at equal intervals. This continuous equal-interval cutting ensures that each conduit is precisely cut to the same length, improving production consistency and efficiency, while avoiding cutting errors and reducing defective products.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-3 As shown, an automatic medical catheter cutting device includes a cutting device 1, a delivery port 101, and a conveyor belt 102. The delivery port 101 is located at the front of the cutting device 1. The conveyor belt 102 is located at the front and rear sides of the cutting device 1 and passes through the delivery port 101. The cutting device 1 works in conjunction with the conveyor belt 102. An equidistant cutting mechanism is provided at the front side of the cutting device 1. The equidistant cutting mechanism includes: a servo motor 201, which is fixedly installed at the rear side of the cutting device 1, and the output shaft of the servo motor 201 passes through to the front side of the cutting device 1; an output gear 202, which is fixedly connected to the output shaft at the front side of the servo motor 201; a rotating gear 203, which meshes with the bottom of the output gear 202 and is rotatably connected to the front side of the cutting device 1; a rotating column 204, which is fixedly connected to the front sides of the output gear 202 and the rotating gear 203 respectively; and two limiting frames 205, both of which are fixedly connected to... On the front side of the cutting device 1, two limiting frames 205 are located at the top and bottom of the conveying port 101; two blade holders 206 are slidably connected to the inside of the two limiting frames 205; two cutting blades 207 are fixedly connected to the inside of the blade holders 206 and are arranged opposite to each other; two round shafts 208 are fixedly connected to the front auxiliary rods 209 of the two blade holders 206, one end of each auxiliary rod 209 is connected to the front side of the cutting device 1 through a rotating shaft, and the other end of each auxiliary rod 209 is slidably connected to the surface of the two round shafts 208. The two auxiliary rods 209 are slidably connected to the surface of the two rotating columns 204. Through the coordinated use of the equidistant cutting mechanism, it can be ensured that each section of the guide has the same length and specifications, which is crucial for product quality control. Moreover, the automated cutting system reduces human factors and avoids length inconsistencies and errors that may be caused by manual operation, thereby improving the overall quality of the product.

[0021] like Figure 1As shown, both auxiliary rods 209 have sliding grooves 3 inside. The rotating column 204 and the round shaft 208 are slidably connected inside the sliding grooves 3. When the two auxiliary rods 209 swing, the sliding grooves 3 allow the rotating column 204 and the round shaft 208 to slide smoothly inside the auxiliary rods 209, reducing friction and motion resistance. This helps ensure that the rotating column 204 and the round shaft 208 drive the auxiliary rods 209 to move more smoothly, making it less likely to jam or produce irregular movements, thus improving the stability of the equidistant cutting mechanism in cutting the guide tube.

[0022] like Figure 1 As shown, both the rotating column 204 and the round shaft 208 are fitted with limiting rings 4. The limiting rings 4 are located on the surface of the auxiliary rod 209. When the rotating column 204 and the round shaft 208 slide inside the auxiliary rod 209, in order to prevent them from detaching from the auxiliary rod 209, the limiting rings 4 can effectively control the rotating column 204 and the round shaft 208 to slide smoothly inside the sliding groove 3.

[0023] like Figures 1-2 As shown, pipe clamps 5 are connected to the surface of the conveyor belt 102. There are several pipe clamps 5, which are evenly distributed on the surface of the conveyor belt 102. The pipe clamps 5 can fix the conduit on the conveyor belt 102, which can prevent the conduit from shifting or moving during transportation or cutting, and ensure that the conduit is always in the predetermined position. This prevents the conduit from shifting or shaking during cutting, which ensures the stability of the conduit throughout the cutting process. The cutting position is more accurate, thereby avoiding unqualified cutting due to inaccurate conduit position and ensuring that the length of each cut segment is consistent.

[0024] like Figure 1 As shown, a support plate 6 is connected between the two conveyor belts 102. A cutting groove is provided on the top of the support plate 6. The support plate 6 enables the conduit to smoothly transition from one conveyor belt 102 to another, preventing the conduit from getting stuck or tilting during the transition. This maintains the smoothness and efficiency of the entire conduit transmission process, prevents the conduit from being flattened or deformed during cutting, and ensures the consistency and quality of the cutting effect.

[0025] like Figure 1As shown, a PLC controller 7 is installed on the front side of the cutting device 1. The PLC controller 7 is electrically connected to the servo motor 201 and the conveyor belt 102. The PLC controller 7 can adjust the rotation speed of the servo motor 201 as needed, thereby precisely controlling the cutting speed of the cutter 207 on the conduit. During the production process, the cutting speed can be flexibly adjusted according to the needs of different specifications of conduits to ensure that each conduit can be cut at the set equidistant interval, avoiding frequent adjustments to the equipment by the staff. At the same time, the PLC controller 7 can ensure that the conduit moves evenly on the conveyor belt 102 at predetermined intervals, thereby achieving equidistant cutting of the conduit and ensuring that each conduit is cut to the same length.

[0026] The working principle of this utility model is as follows: When cutting the conduit, the conduit can first be placed between the pipe clamps 5 on the conveyor belt 102 to limit the conduit on the conveyor belt 102. Then, the conveyor belt 102 is run to transport the conduit, and at the same time, the servo motor 201 is run. The operation of the servo motor 201 will drive the output gear 202 to rotate. The rotation of the output gear 202 will drive the meshing rotating gear 203 to rotate in the opposite direction. The simultaneous rotation of the rotating gear 203 and the output gear 202 will drive the rotating column 204 to rotate. The rotation of the rotating column 204 will slide inside the auxiliary rod 209 and drive one end of the two auxiliary rods 209 to swing up and down around the rotating shaft. When the two auxiliary rods 209 are in the same position... When the device swings up and down, it causes the blade holder 206 and the cutting shears 207 to move smoothly up and down inside the limit frame 205. When the two auxiliary rods 209 move inward at the same time, they can also cause the blade holder 206 and the cutting shears 207 to move inward at the same time inside the limit frame 205, and automatically cut the guide tubes conveyed on the conveyor belt 102. As the output gear 202 drives the meshing rotating gear 203 to rotate continuously, it can continuously cut the guide tubes on the conveyor belt 102 at equal intervals. Continuous equal interval cutting can ensure that each guide tube is precisely cut to the same length, which improves the consistency and efficiency of production, while avoiding the error caused by cutting and reducing the generation of defective products.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
