[0083] Furthermore, the containing box 103 includes a box body 201 and a pressing plate 203. The pressing plate 203 is arranged in the box body 201. The pressing plate 203 is pressed on the packaging bag with cotton swabs in the box body 201 and moves as the number of packaging bags decreases. A bag outlet hole is provided on the front side of the bottom of the box body 201. An avoidance groove 205 connected to the bag outlet hole 204 is provided at the bottom position of the box body 201 in front of the bag outlet hole. The avoidance groove 205 can enable the cotton swabs with the packaging bag to pass through, so as to avoid the cotton swabs in the packaging bag from hitting the front side wall inside the box body 201. The upper end of the box body 201 is set to an opening shape, and a limit pin 206 is provided on the box body 201 at the opening of the upper end of the box body 201. A limit groove 207 corresponding to the limit pin 206 is provided on the pressing plate 203. The limit pin 206 limits the upward movement of the pressing plate 203 to avoid the pressing plate 203 from separating from the box body 201.

[0084] Furthermore, a packaging bag insertion hole 208 is provided on the left side or right side of the box body 201, and the front-to-back width of the packaging bag insertion hole 208 is smaller than the front-to-back width of the inner cavity of the box body 201, and the two ends of the packaging bag can be stuck in the box body 201 on both sides of the packaging bag insertion hole 208.

[0085] Furthermore, a strip groove 209 is provided at the bottom of the box body 201 on the rear side of the bag outlet hole 204, and the front end of the strip groove 209 is connected to the bag outlet hole 204. The left-right width of the strip groove 209 is smaller than the left-right width of the bag outlet hole 204, so that the bottoms of the left and right sides of the strip groove 209 form side wings 210 for supporting the two sides of the packaging paper. The design of the avoidance groove 205 increases the operating space of the paper taking mechanism under the bag outlet hole 204, and at the same time, the packaging paper can be dragged by the side wings 210 to avoid large friction between the upper and lower layers of packaging paper, making it easy to take out two or more layers.

[0086] Furthermore, the front and rear sides of the lower end of the pressing plate 203 are respectively provided with end grooves 211 connected to the front and rear sides of the inner cavity of the box body 201. The function of the end grooves 211 is to prevent the two ends of the packaging bag from being stuck in the gap between the pressing plate 203 and the inner wall of the box body 201.

[0087] Furthermore, a pressing plate counterweight 212 is provided at the upper end of the pressing plate 203, and the pressing plate counterweight 212 is used to enable the pressing plate 203 to move downward when the number of packaging bags decreases.

[0089] 2. The material picking and delivering mechanism 2 described above includes a suction component and a delivering component. The suction component includes a suction cup 301, a cylinder 302, and an adsorption driver. The suction cup 301 is connected to the cylinder 302 via a pipeline, and the suction cup 301 is connected to the adsorption driver. The suction cup 301 is arranged below the bag outlet 204. The delivering component includes a delivery driver 303 and a drive plate 304. The delivery driver 303 is fixed on the frame (as shown in the figure, it is fixed on the holding support frame 101 through a connecting rod). The delivery driver 303 is connected to the drive plate 304, and the drive plate 304 is connected to the adsorption driver in the suction component. The suction cup 301 is driven to move up for adsorption by the adsorption driver, and the delivery driver 303 drives the packaging bag adsorbed by the suction cup 301 to be delivered.

[0090] Furthermore, the adsorption driver includes a support plate 305, a first driving block 306, a first linear guide rail 307 and a limiting slide plate 308. The suction cup 301 is fixed on the support plate 305. The support plate 305 is connected to the driving plate 304 via the first linear guide rail 307. The lower end of the support plate 305 is connected to the first driving block 306. The limiting slide plate 308 is fixed to the frame. The limiting slide plate 308 is provided with a slideway inclined toward the lower front side. The first driving block 306 is slidably connected to the slideway on the limiting slide plate 308. The suction cup 301 After the packaging bag is adsorbed, the driver drives the driving plate 304 to move, and the driving plate 304 drives the support plate 305 to move toward the front side. Since the support plate 305 is connected to the driving plate 304 via a linear slide rail, the support plate 305 moves toward the front side and moves downward at the same time due to the action of the slide rail during the process of the support plate 305 moving toward the front side. Therefore, the suction cup 301 drives the packaging bag to move toward the bottom of the front side to separate from the upper packaging bag. In the process of the suction cup 301 moving downward, the friction between two adjacent packaging bags can be avoided from increasing, thereby avoiding the removal of two or more packaging bags.

[0091] Furthermore, the first connecting rod 309 and the second connecting rod 310 are connected between the delivery driver 303 and the drive plate 304, the first connecting rod 309 is hinged to the driver output shaft, the second connecting rod 310 is hinged to the first connecting rod 309, and the second connecting rod 310 is hinged to the drive plate 304. Through the action of the secondary connecting rod, the stroke between the delivery driver 303 and the drive plate 304 is shortened, and the space occupied by the delivery component is reduced.

[0092] Furthermore, the slide includes an inclined slide and a horizontal slide. The inclined slide is inclined toward the front and lower side, and the rear end of the horizontal slide is continuously connected to the lower end of the inclined slide. In this way, the inclined slide only plays the role of moving the suction cup 301 downward after adsorption, while the horizontal slide is used for sending out after adsorption by the suction cup 301, saving space.

[0093] Furthermore, the slideway on the limiting slide plate 308 is configured as a slide hole, and the slide hole is configured as a slide hole inclined toward the front and lower sides, and the first driving block 306 is inserted into the slide hole to realize the slide hole connection.

[0094] Furthermore, the sliding hole includes an oblique sliding hole 312 and a horizontal sliding hole 311. The oblique sliding hole 312 is inclined toward the front and lower side, and the rear end of the horizontal sliding hole 311 is continuously connected to the lower end of the oblique sliding hole 312. In this way, the oblique sliding hole 312 only plays a role in moving the suction cup 301 downward after adsorption, while the horizontal sliding hole 311 is for sending out the suction cup 301 after adsorption, saving space.

[0095] Furthermore, the driving plate 304 is slidably connected to the frame (fixed on the containing support frame 101 via a connecting rod as shown in the figure) via a third linear guide rail 313 .

[0096] The bag taking process is as follows: when the present invention is in use, first, the original position of the first driving block 306 is at the top of the inclined slide, at this time, the cylinder 302 is started, the suction cup 301 absorbs a packaging bag at the bag outlet hole 204 position stacked on the box body 201, and then the delivery driver 303 is started, the delivery driver 303 drives the driving plate 304 to move forward, and the driving plate 304 drives the supporting plate 305 to move forward. In the process of the supporting plate 305 moving forward, due to the action of the first driving block 306 at the lower end of the supporting plate 305, the first driving block 306 first moves up and down on the inclined slide, and then drives the supporting plate 305 to move downward through the first driving block 306, and the packaging bag absorbed by the suction cup 301 moves downward, thereby separating the two adjacent packaging bags, avoiding direct During the forward movement, the friction between two adjacent packaging bags is too large, which directly causes two or more packaging bags to fall out. The first driving block 306 moves forward along the slide, so that the support plate 305 drives the suction cup 301 and the packaging bag to be sent out together, thereby completing the sending action. After sending out, the bag needs to be taken out again, so the sending driver 303 drives the driving plate 304 to move backward, moves the first driving block 306 to the top of the inclined slide, and starts the cylinder 302 again. The suction cup 301 is adsorbed again, and the above action is repeated to take out the next packaging bag. After the packaging bag in a box body 201 is completely taken out, the holding frame driving motor 104 drives the holding frame 102 to move until the next box body 201 moves to the suction cup 301 position.

[0097] The delivery driver 303 described above is a driving motor, the linear slide rail is a mechanism that can realize the relative sliding of the support plate 305 and the driving plate 304, and the connection between the suction cup 301 and the cylinder 302 is all prior art, which will not be described here. Moreover, for the above-named plates, blocks and other structures, they are not limited to being made according to plates or blocks in actual production, as long as the connection function can be realized. The placement position of the box body 201 and other mechanisms can be placed horizontally or vertically, and the up-down, front-back, left-right position relationship is not within the scope of the position relationship limitation of this patent. Moreover, due to the box body 201 with this structural shape, its pressing plate 203 can move as the number of packaging bags decreases. At the same time, since the left side or right side of the box body 201 is provided with a packaging bag insertion hole 208, when entering When placing the strip-shaped packaging bags in a row, the packaging bags can be tilted and placed in the box body 201, and then the packaging bags can be rotated to place the packaging bags in the box body 201. As the number increases, when multiple packaging bags are stacked and released, due to the elastic effect of the packaging bags themselves, they expand toward the opening of the box body 201, and the pressing plate 203 can press the multiple stacked packaging bags under the action of the limiting pin 206 to prevent the packaging bags from falling out of the box body 201. The limiting pin 206 can be provided with two, and the pressing plate 203 is provided with a limiting groove 207 corresponding to the limiting pin 206. The two limiting pins 206 are respectively arranged on the left and right sides of the inner cavity of the box body 201, which can stabilize the position of the pressing plate 203. Due to the provision of the box body 201 of this scheme, more packaging bags with cotton swabs can be stored and less space is occupied. Due to the adoption of the above-mentioned structure, the present invention has the advantages of simple structure, high removal efficiency, good removal effect, small space occupation, large number of storage, and the ability to realize the delivery of a single throat swab cotton swab packaging bag.

[0098] The above is the bag taking process. A bag taking port can be provided on the machine body. The packaging bag adsorbed by the adsorption component is directly extended through the bag taking port by the delivery component. After the inspection personnel take the packaging bag, they can directly tear open the packaging bag for inspection. The bag taking process can also be used directly in the machine body in conjunction with a mechanism in the machine body that can open the packaging bag and grab the cotton swab.

Since the cotton swab head is covered by the test tube cover, the rotation process of the cotton swab stick can realize the separation of the cotton swab head from the cotton swab stick. The driver is the driving motor.

[0108] Clamping and transferring process: After the detection personnel finish sampling, they insert the rear end of the cotton swab into the through hole 425. Since the through hole 425 is provided with a discharge rod 415, the inserted cotton swab cannot be inserted any further and stops. After insertion, the second driving motor 412 is started to drive the second driving block 411 to move, and the cotton swab is moved to the cotton swab head breaking or shearing position, and the cotton swab head is unloaded into the test tube.
