[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0026] like Figure 1-3 As shown, the utility model provides a device for punching and cutting edges of rubber plugs, including a punching mechanism 1, a rotating mechanism 2 and a rubber edge cleaning mechanism 4. The punching mechanism 1 includes a telescopic member 11, a circular cutting blade 12 and a dividing cutting blade 13. The circular cutting blade 12 and the dividing cutting blade 13 are arranged at the telescopic end of the telescopic member 11. The circular cutting blade 12 is annular in shape, and the dividing cutting blade 13 is sheet-shaped. Several of the circular cutting blades 12 are arranged linearly, and their number corresponds to the number of medical rubber plugs that need to be punched and cut edges. The dividing cutting blade 13 is arranged between two adjacent circular cutting blades 12 and outside the circular cutting blades 12 at both ends, and is used to cut the rubber edge. The annular rubber edge can be cut from the middle and divided into two sections, which is convenient for cleaning from both sides; the rotating end of the rotating mechanism 2 is detachably provided with a replacement plate 3, which is used to rotate and drive the replacement plate 3 to move to the bottom of the punching mechanism 1, and the rubber plug is moved by the rotating mechanism 2 to move the upper and lower parts. The replacement plate 3 of the rubber plug is moved to the bottom of the punching mechanism 1, and then the telescopic member 11 pushes the annular cutting blade 12 and the dividing cutting blade 13 upward to punch and cut the edges of the medical rubber plug. The replacement plate 3 is provided with a plurality of linearly arranged insertion slots 301 for inserting the rubber plug. The medical rubber plugs are first inserted into the insertion slots 301 one by one to locate the positions, and then the replacement plate 3 is rotated and replaced by the rotating mechanism 2, so that a plurality of medical rubber plugs can be moved to the punching mechanism 1 at one time to punch and cut the edges, thereby improving the efficiency of removing the rubber edges. The rubber edge cleaning mechanism 4 includes an air nozzle 41, and a plurality of the air nozzles 41 are arranged on both sides of the plurality of the annular cutting blades 12 for blowing downward. After the rubber edges are cut by the annular cutting blade 12 and the dividing cutting blade 13, segmented rubber edges are obtained. Then, the air nozzle 41 is used to blow downward to blow the cut segmented rubber edges off from both sides of the replacement plate 3, thereby achieving the purpose of automatic cleaning.

[0027] It can be understood that the size of the cutting blade 12 matches the outer diameter of the medical plug. When cutting, the excess rubber edge can be cut off, and the dividing blades 13 on both sides can be used to divide the annular rubber edge into two sections, the front side and the rear side, and then blown off the replacement plate 3 by the air nozzle 41 for cleaning; if it is necessary to increase the number of medical plugs punched at one time, the number of insertion slots 301 of the array can be increased along the array direction, and the number of dividing blades 13 and the cutting blades 12 can be increased synchronously; the air nozzle 41 can be connected to the compressed air cylinder through an air pipe, and the compressed air is provided by the compressed air cylinder. When the electric control valve is opened, the air in the compressed air cylinder is released and sprayed out from the air nozzle 41, or the air nozzle 41 can also be connected to the air pump through a pipeline, and the air pump supplies air to provide the gas sprayed by the air nozzle 41 to blow and clean the cut rubber edge; the telescopic member 11 can adopt a hydraulic cylinder push rod, a cylinder push rod and other structural members with reciprocating telescopic function.

[0028] Furthermore, in order to collect the blown-off rubber edges in a centralized manner, the rubber edge cleaning mechanism 4 also includes a collecting groove 42, which is arranged directly below the punching mechanism 1 and below the replacement plate 3. The collecting groove 42 is used to collect the blown-off rubber strips. The length and width of the collecting groove 42 are respectively greater than the length and width of the replacement plate 3, so that it can cover both sides of the replacement plate 3 to prevent the blown-off rubber strips from falling outside the range of the collecting groove 42, thereby improving the centralized collection rate of the rubber strips.

[0029] It can be understood that the collecting groove 42 extends from directly below the replacement plate 3 to both sides and is outwardly expanded to ensure that there is a sufficient material receiving area.

[0030] Furthermore, in order to facilitate the removal of the rubber strips collected in the collecting groove 42, a guide hopper 43 is provided on one side of the collecting groove 42, and the guide hopper 43 is connected to the interior of the collecting groove 42 and is inclined downward. By cleaning the interior of the collecting groove 42, the rubber strips collected therein are cleaned to the open opening connected to the guide hopper 43, and then slide down from the open opening along the guide hopper 43 and are caught by a trash can at the bottom of the guide hopper 43, which is easy to operate.

[0031] In this embodiment, in order to control the rotational displacement angle of the replacement plate 3, the rotating mechanism 2 includes a stepper motor 21 and a rotating disk 22, wherein the rotating disk 22 is arranged on the output shaft of the stepper motor 21, and the rotation angle of the rotating disk 22 is controlled by the stepper motor 21. The rotating disk 22 has a support plate 23 extending outward, and the support plate 23 is used to support the replacement plate 3. The support plate 23 is provided with an insertion column 201, and the number of the insertion columns 201 is two, or the shape is a bar. The replacement plate 3 is provided with an insertion hole 302, and the insertion column 201 is plugged into the insertion hole 302. The installation position of the replacement plate 3 is located by plugging the insertion column 201 into the insertion hole 302.

[0032] It can be understood that after the rubber plugs are fully inserted into all the insertion slots 301 on the replacement plate 3, the replacement plate 3 can be directly installed on the support plate 23. After the edges are punched out, the replacement plate 3 can be directly removed and the rubber plugs thereon can be quickly removed.

[0033] Furthermore, the number of the replacement plates 3 is at least two, and several of the replacement plates 3 are distributed in a circle on the rotating disk 22. There are two replacement plates 3, one of which corresponds to punching and cutting edges under the punching mechanism 1, and the other corresponds to the far end for inserting the rubber plug and unloading the rubber plug that has been punched and cut and returned to the position. One side is the punching position, and the other side is the loading and unloading position.

[0034] It can be understood that when there are three replacement plates 3, the punching position is directly below the punching mechanism 1, and the other two replacement plate 3 positions are one loading position and the other unloading position, which are used for inserting the rubber plug, punching and cutting edges, and removing the rubber plug, respectively. Under the rotation drive of the stepper motor 21, the replacement plate 3 is rotated at the work station.

[0035] Furthermore, in order to facilitate unloading, the replacement plate 3 includes a bottom plate 31 and a flip plate 32. The flip plate 32 is hinged at the top of the bottom plate 31 and is used to flip to one side. When the replacement plate 3 is rotated to the unloading position, the flip plate 32 is directly flipped, and the medical plug inserted in the insertion slot 301 is facing downward. The medical plug can be simply pushed and pulled to fall off from the insertion slot 301 downward, which is convenient for unloading.

[0036] The insertion hole 302 is provided on the bottom plate 31 , and the insertion slot 301 is provided on the flip plate 32 .

[0037] In this embodiment, in order to stabilize the bottom structure, a base 24 is further provided at the bottom of the stepper motor 21 , and an anti-slip pad is provided at the bottom of the base 24 , wherein the collecting tank 42 is fixedly mounted on the base 24 via a bracket.

[0038] It can be understood that the maximum outer diameter of the base 24 is greater than the outer diameter of the stepper motor 21 .

[0039] Furthermore, a collecting box 25 is detachably provided on the base 24, and the collecting box 25 is used to collect the removed rubber plugs.

[0040] It can be understood that the collection box 25 can also be used as a raw material box for accommodating rubber plugs that have not been trimmed.

[0041] Furthermore, an iron sheet is provided on one side of the collection box 25, and a magnetic sheet is provided on the side of the base 24 corresponding to the iron sheet, so that the collection box 25 can be quickly positioned through the rapid magnetic attraction between the iron sheet and the magnetic selection sheet.

[0042] Furthermore, a plurality of universal wheels are provided at the bottom of the collection box 25 , and a handle is provided on the outer side of the collection box 25 , so as to facilitate the transfer and transportation of the collection box 25 .

[0043] The specific working process of the utility model is as follows: the number of replacement plates 3 and support plates 23 are both three, and the rotating area of ​​the rotating disk 22 is divided into three stations, namely, a loading station, a punching station and a unloading station. At the loading station, the medical plugs are sequentially filled into the corresponding insertion slots 301; the rotating disk 22 is driven by the stepping motor 21 to rotate 120°, the stations are rotated, the replacement plate 3 is moved to the punching station, the annular cutting blade 12 and the dividing cutting blade 13 are pushed downward by the telescopic member 11 to move, the rubber edge is cut off, and synchronously, air is blown through the air nozzle 41 to cut the cut segments. The rubber edge is blown into the collecting tank 42 for collection; the rotating disk 22 is then driven by the stepping motor 21 to rotate 120°, the workstations are rotated, the replacement plate 3 is moved to the unloading station, the flip plate 32 is flipped, the medical rubber plug with the cut rubber edge is facing in the opposite direction, and the medical rubber plug can be pushed and swept by hand to fall downward into the collection box 25. According to the above principle, the other two replacement plates 3 are also loaded, punched and unloaded in turn, and multiple medical rubber plugs can be punched at a time, which not only maintains the efficiency of punching and cutting the rubber edges, but also automatically collects the cut rubber edges, reducing the manual workload.
