In this embodiment, the first ratchet 2201 and the second ratchet 2202 may be disposed on the rotating shaft of the first driving motor 221 to achieve synchronous transmission of the first ratchet 2201 and the second ratchet 2202, and the feeding assembly 220 is configured to transport the throat swab chain type packaging bag 100 by matching the protrusions 2221 on the first ratchet 2201 and the second ratchet 2202 with the positioning holes 112 on the bag unit.

In this embodiment, the first ratchet 2201 and the second ratchet 2202 are directly connected to the first driving motor 221 without a belt or a pulley, thereby saving the internal space of the housing 210 and the production cost.

Referring to fig. 18 of fig. 14, in some embodiments, the stripping assembly 230 includes: a third driving motor 231 provided in the housing 210; the first friction wheel 232 and the second friction wheel 233 are arranged on the upper side of the transmission channel, the first friction wheel 232 and the second friction wheel 233 are both arranged on a rotating shaft of the third driving motor 231, the first friction wheel 232 and the second friction wheel 233 can be respectively positioned on two sides of the throat swab 120 to be peeled, and both the first friction wheel 232 and the second friction wheel 233 can abut against the upper surface of the bagged unit 111 to be peeled.

In some embodiments, the first friction wheel 232 and the second friction wheel 233 are irregular friction wheels, the surface of the irregular friction wheel includes an arc-shaped abutting surface 2321 and a non-contact surface 2322, the arc-shaped abutting surface 2321 can abut against the upper surface of the bagged unit 111 to be peeled, and the non-contact surface 2322 is spaced from the upper surface of the bagged unit 111 to be peeled.

In specific implementation, when the feeding assembly 220 conveys the bagged unit 111 to be peeled to the material peeling station, the third driving motor 231 is started to drive the first friction wheel 232 and the second friction wheel 233 to rotate, in the rotating process of the first friction wheel 232 and the second friction wheel 233, when the arc-shaped abutting surface 2321 faces one side of the conveying channel, the arc-shaped abutting surface 2321 is matched with the housing cover 2121 of the lower housing 212, the bagged unit 111 is clamped between the arc-shaped abutting surface 2321 and the surface of the housing cover 2121, the surfaces of the arc-shaped abutting surface 2321 and the housing cover 2121 are respectively in frictional contact with the upper surface and the lower surface of the bagged unit 111, under the action of friction, the first end of the bagged unit 111 and the pharyngeal swab 120 inside the bagged unit are driven to move towards the discharge port 214, at this time, because the second end of the bagged unit 111 is fixed on the feeding assembly 220 through the positioning hole 112, the pharyngeal swab 120 can be ejected out from the second end of the bagged unit 111, the second end of the bagged unit 111 is torn, and the second end of the pharyngeal swab is exposed out of the discharge port 214.

When the arc-shaped abutting surface 2321 faces one side of the transmission channel, the bagged unit is clamped between the arc-shaped abutting surface 2321 and the surface of the housing cover 2121, which is inconvenient for the feeding assembly 220 to transmit the throat swab chain type packaging bag 100.

Therefore, when the feeding assembly 220 is required to convey the pharyngeal swab chain package 100, the non-contact surface 2322 can be made to face one side of the conveying channel, and the non-contact surface 2322 is not in contact with the upper surface of the bag unit 111 to be peeled, so that the feeding assembly 220 can drive the pharyngeal swab chain package 100 to convey.

In some embodiments, the irregular friction wheel is an arcuate friction wheel (as shown in fig. 17), the arc-shaped abutting surface 2321 is an arc-shaped abutting surface, and the non-contact surface 2322 is a plane.

In other embodiments, the irregular friction wheel may also be disposed in other shapes, and only needs to be able to intermittently abut against the irregular friction wheel with the upper surface of the to-be-peeled bagged unit 111 during the rotation process.

Referring to fig. 14, 15 and 18, in some other embodiments, the first friction wheel 232 and the second friction wheel 233 may be a pair of circular friction wheels. At this time, the stripping assembly 230 further includes a lifting assembly 234 engaged with the circular friction wheel, the lifting assembly 234 is disposed in the housing 210 and located at the lower side of the transmission channel, and the lifting assembly 234 can abut against the lower surface of the bagged unit 111 to be stripped.

Specifically, the lifting component 234 can perform a lifting or lowering motion, when the lifting component 234 is lifted, the lifting component 234 cooperates with the pair of circular friction wheels to clamp the bagged unit 111 to be peeled between the lifting component 234 and the circular friction wheels, so that the bagged unit 111 moves along the direction of the discharge port 214 under the action of friction force, at this time, since the second end of the bagged unit 111 is fixed on the feeding component 220 through the positioning hole 112, the pharyngeal swab 120 is ejected from the second end terminal of the bagged unit 111, the second end terminal of the bagged unit 111 is torn, and the second end of the pharyngeal swab 120 is exposed to the discharge port 214.

When the lifting assembly 234 descends, there is a gap between the bagging unit 111 and the lifting assembly 234 and the circular friction wheel, and the feeding assembly 220 can drive the throat swab chain package 100 to transport.

In some embodiments, the lifting assembly 234 includes a second driving motor 2341, a cam 2342, a connecting member 2343, a first supporting member 2344 and a second supporting member 2345; the cam 2342 is fixedly connected with a rotating shaft of the second driving motor 2341; one end of the connecting piece 2343 is connected with the cam 2342; the first supporting member 2344 and the second supporting member 2345 are both connected to the other end of the connecting member 2343, the first supporting member 2344 corresponds to the first friction wheel 232, the second supporting member 2345 corresponds to the second friction wheel 233, and the first supporting member 2344 and the second supporting member 2345 can be respectively located at two sides of the throat swab 120 to be peeled and can be abutted against the lower surface of the bagged unit 111.

The second driving motor 2341 is disposed at the lower casing, the cam 2342, the connecting member 2343, the first supporting member 2344 and the second supporting member 2345 are disposed at the lower side of the conveying passage and correspond to the second area 114, the first friction wheel 232 and the second friction wheel 233 are disposed at the upper side of the conveying passage and correspond to the second area 114, the second driving motor 2341 can drive the first supporting member 2344 and the second supporting member 2345 to move towards the first friction wheel 232 and the second friction wheel 233 respectively, so that the first end (corresponding to the second area 114) of the pouch unit 111 is clamped between the first supporting member 2344 and the first friction wheel 232 and between the second supporting member 2345 and the second friction wheel 233, at this time, the first supporting portion 116 and the second supporting portion 117 abut against the first friction wheel 232 and the second friction wheel 233 respectively, and the third supporting portion 118 and the fourth supporting portion 119 abut against the first supporting wheel 244 and the second supporting wheel 245.

In some embodiments, the first retaining member 2344 and the second retaining member 2345 may be regular or irregular in shape, for example, the first retaining member 2344 and the second retaining member 2345 may be square, circular, etc.

In some embodiments, the first and second engaging members 2344 and 2345 are located directly below the first and second engaging wheels, respectively, so as to match the first and second friction wheels 232 and 233.

After the second driving motor 2341 is started, the second driving motor 2341 drives the cam 2342 to rotate, the rotation of the cam 2342 drives the connecting piece 2343 to move up and down, and further drives the first supporting piece 2344 and the second supporting piece 2345 to move up and down, when the first supporting piece 2344 and the second supporting piece 2345 respectively move towards the first friction wheel 232 and the second friction wheel 233, the first end (corresponding to the second area 114) of the bagging unit 111 is clamped between the first friction wheel 232 and the first supporting piece 2344 and between the second friction wheel 233 and the second supporting piece 2345, at this time, the first friction wheel 232 and the second friction wheel 233 respectively support the first supporting portion 116 and the second supporting portion 117, and the first supporting piece 2344 and the second supporting piece 2345 respectively support the third supporting portion 118 and the fourth supporting portion 119.

The third driving motor 231 is disposed on the upper housing 211, and the third driving motor 231 can drive the first friction wheel 232 and the second friction wheel 233 to rotate.

After the first end of the pouch unit 111 is clamped between the first friction wheel 232 and the first supporting member 2344 and between the second friction wheel 233 and the second supporting member 2345, the third driving motor 231 is started, and at this time, the first friction wheel 232 and the second friction wheel 233 rotate to drive the first end of the pouch unit 111 and the throat swab 120 therein to move toward the discharge port 214 under the action of friction force, and at this time, because the second end of the pouch unit 111 is fixed on the feeding component 220 through the positioning hole 112, the throat swab 120 is ejected out from the second end of the pouch unit 111, the second end of the pouch unit 111 is torn, and the second end of the throat swab 120 is exposed out of the discharge port 214.

It should be noted that, because the first ends of two adjacent bagging units 111 are separated by the cutting line 115 in the second region 114, when the first friction wheel 232 and the second friction wheel 233 rotate, the current bagging unit 111 to be peeled in the second region 114 can be easily separated from the adjacent bagging unit 111, so that in the peeling process of the current bagging unit 111 to be peeled, the adjacent bagging unit 111 is not damaged, and the peeling of the current bagging unit 111 to be peeled is not affected by the adjacent bagging unit 111.

Besides, in the above embodiment, the first supporting member 2344 and the second supporting member 2345 are driven to ascend and descend, and in other embodiments, the first supporting member 2344 and the second supporting member 2345 can be driven to ascend and descend by a steering motor, an electromagnet, an electric push rod, an electric cylinder, an air cylinder and the like.

In some embodiments, the third driving motor 231 is a forward/reverse rotation motor, and the first friction wheel 232 and the second friction wheel 233 can be driven to rotate forward or reverse by the third driving motor 231. For convenience of explanation, in the embodiment of the present invention, the first end of the bagging unit 111 is set to move toward the discharge port 214 when the third driving motor 231 rotates forward.

In some embodiments, since the second end of the pouch unit 111 is fixed, when the first end of the pouch unit 111 moves towards the discharge port 214, the pouch unit 111 at this time may be entirely in a folded shape, so that the resistance of the throat swab 120 to be pulled out is increased, the throat swab 120 is difficult to be pulled out, and the throat swab 120 is easily damaged, therefore, in order to ensure that the throat swab 120 can be easily pulled out, the pouch unit 111 in the folded shape needs to be flattened and restored, however, if the first end of the pouch unit 111 is retracted and flattened only by the reverse rotation of the third driving motor 231, the throat swab 120 is also retracted while the first end of the pouch unit 111 is retracted, and therefore, the present invention further provides the non-return assembly 250, where the non-return assembly 250 is disposed at a side close to the discharge port 214, and after the second end of the pouch unit 111 is torn, the non-return assembly 250 is configured to fix the second end of the throat swab 120, so that the throat swab 120 does not move together with the pouch unit 111.

Specifically, after the second end of the throat swab 120 is exposed out of the bagged unit 111, the third driving motor 231 reversely rotates to drive the first end of the bagged unit 111 to retreat so as to flatten the bagged unit 111 as a whole, and meanwhile, the retreat-preventing component 250 fixes the second end of the throat swab 120, so that the throat swab 120 cannot retreat along with the bagged unit 111, and therefore the throat swab 120 is prevented from being taken out due to the fact that the bagged unit 111 is folded, the peeling effect is ensured, and the working efficiency is improved.

In some embodiments, the retaining assembly 250 comprises a first bearing seat 251 and a second bearing seat 252, a rotating shaft 253, a third conveyor belt 254, and a retaining plate 255, wherein the first bearing seat 251 and the second bearing seat 252 are disposed near the second end of the bagging unit 111; the rotating shaft 253 is arranged on the first bearing seat 251 and the second bearing seat 252, and the rotating shaft 253 is parallel to the rotating shaft of the third driving motor 231 and is located on the upper side of the transmission channel; the third belt 254 is connected between the rotation shaft of the third driving motor 231 and the rotation shaft 253; the retaining plate 255 is disposed on the rotating shaft and located between the first bearing seat 251 and the second bearing seat 252, and the third conveyor belt 254 can drive the rotating shaft 253 to rotate, so that the retaining plate 255 presses the second end of the throat swab 120.

In this embodiment, the existing stripping assembly 230 is skillfully utilized, and is connected to the rotating shaft and the rotating shaft 253 of the third driving motor 231 through the third conveyor belt 254, and the retaining plate 255 is fixed on the rotating shaft 253, so that when the third driving motor 231 rotates reversely, the third conveyor belt 254 is driven to rotate, and then the first rotating shaft 253 is driven to rotate, so that the retaining plate 255 presses the throat swab 120. That is, when the third driving motor 231 rotates reversely, not only the bag unit 111 at the stripping station is driven to retract, but also the anti-retraction plate 255 is driven to move so as to fix the pharyngeal swab 120, so that the bag unit 111 at the stripping station retracts and the position of the pharyngeal swab 120 is fixed.

In the above embodiment, the retaining plate 255 provides the driving force through the third driving motor 231, so that an additional driving mechanism is not required, the internal space of the housing 210 is effectively saved, and the production cost is reduced.

In other embodiments, the backstop assembly 250 can be equally used by providing electromagnets, stepper motors, gear motors, etc., but these all add economic cost and structural complexity.
