Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] Please see Figs. 1-7 According to one embodiment of the present invention, a specimen retrieval bag sealing mechanism includes a device body 1, and further includes:

[0043] Mounting component 2 is used to place the continuous roll-up bag;

[0044] An opening assembly 3, connected to the device body 1, is used to open the continuous roll-up bag. The opening assembly 3 includes a motor 301, a rotating shaft B302, and a fan blade 303. The motor 301 is connected to the rotating shaft B302 via a transmission pair A304. The rotating shaft B302 is rotatably connected to the device body 1. The motor 301 is detachably connected to the device body 1. The fan blade 303 is fixedly connected to the output shaft of the motor 301.

[0045] The export component 4 is connected to the motor 301 via the intermittent drive mechanism 7 and is used to release the continuously rolled-up bag;

[0046] The heat-sealing mechanism 6, connected to the motor 301 via the intermittent drive mechanism 7, is used to seal the retrieval bag; and

[0047] The flaring mechanism 8 is connected to the device body 1 and is used to flare the retrieval bag.

[0048] An intermittent drive mechanism 7 is connected to the discharge assembly 4 and the hot-melt mechanism 6, and is used to intermittently drive the discharge assembly 4 and the hot-melt mechanism 6. The intermittent drive mechanism 7 includes a rotating shaft F701, a rotating shaft G702, a rotating shaft H703, a transmission assembly A704, and a transmission assembly B. The rotating shafts F701, G702, and H703 are all rotatably connected to the device body 1. The rotating shaft F701 is connected to the motor 301 through the transmission assembly A704. The rotating shaft G702 is connected to the discharge mechanism, and the rotating shaft H703 is connected to the hot-melt mechanism 6.

[0049] The transmission component B includes an incomplete gear 705, a spur gear A706, and a spur gear B707. The incomplete gear 705 is fixedly connected to the rotating shaft F701, the spur gear A706 is fixedly connected to the rotating shaft H703, and the spur gear B707 is fixedly connected to the rotating shaft G702. The incomplete gear 705 intermittently meshes with the spur gears A706 and B707.

[0050] Specifically, the transmission component A704 is a worm gear pair. As those skilled in the art should know, the purpose of setting the transmission component A704 as a worm gear pair is to convert the rotational motion of the output shaft of the motor 301 into the rotational motion of the rotating shaft F701 in the horizontal direction with the rotation axis perpendicular to the output shaft of the motor 301. Therefore, in some embodiments, as an alternative to the worm gear pair, the transmission component A704 includes pulley A, pulley B, and a transmission rope. The pulley A is sleeved on the output shaft of the motor 301 and fixedly connected to it. The pulley B is sleeved on the rotating shaft F701 and fixedly connected to the rotating shaft F701. The pulley A is connected to the pulley B through the transmission rope, and the transmission rope is in the shape of an 8 in space.

[0051] Specifically, the export component 4 includes a rotating shaft C401, a rotating shaft D402, a gear pair 403, and flexible sleeves 404. Both rotating shafts C401 and D402 are rotatably connected to the device body 1. Rotating shaft C401 is connected to rotating shaft D402 via gear pair 403. The two flexible sleeves 404 are correspondingly and fixedly fitted onto rotating shafts C401 and D402. Rotating shaft C401 is connected to rotating shaft G702 via coupling A. Rotating shaft G702 drives rotating shaft C401 to rotate horizontally. Rotating shaft C401, via gear pair 403, drives rotating shaft D402 to rotate horizontally in the opposite direction to rotating shaft C401. At this time, the two flexible sleeves 404, through linear movements in opposite directions, export the continuously rolled bag from the device body 1. The purpose of this arrangement is to cooperate with the opening component 3 to export the continuously rolled bag from the device body 1 and open it.

[0052] Specifically, the mounting assembly 2 includes a rotating shaft A201 and an insert shaft 202. The two rotating shafts A201 are symmetrically rotatably connected to the device body 1. One end of the insert shaft 202 extends into the rotating shaft A201 and slides within it. An elastic element A (not shown in the figure) is provided inside the insert shaft 202. The elastic element A is fixedly connected to the rotating shaft A201 and the insert shaft 202. A baffle (not shown in the figure) is fitted and fixedly connected to the insert shaft 202. Those skilled in the art can install the continuous roll-up bag by inserting the roll of the continuous roll-up bag into one insert shaft 202. At this time, the insert shaft 202 located within the rotating shaft A201 pushes the rotating shaft A201, causing the continuous roll-up bag inserted thereon to be inserted into the other insert shaft 202.

[0053] Specifically, the elastic element A is a spring. Those skilled in the art should know that the purpose of setting the elastic element A as a spring is to provide flexible support for the insertion shaft 202. Therefore, in some embodiments, the elastic element A can also be set as any one of a compression spring, an elastic steel plate, and an elastic telescopic sleeve.

[0054] Specifically, the hot-melt mechanism 6 includes a lead screw B601, a push plate A602, a push plate C603, and a hot-melt plate 606. The push plate A602 is threadedly connected to the lead screw B601 and passes through the push plate C603. The lead screw B601 is rotatably connected to the device body 1. The hot-melt plate 606 is embedded in the push plate C603 and is detachably connected to the push plate C603 via a bolt assembly. It also includes:

[0055] The elastic telescopic component 604 is connected to push plate A602 and push plate C603, and is used to connect push plate A602 and push plate C603; and

[0056] The transmission assembly C9 is connected to the lead screw B601 and the rotating shaft H703, and is used to drive the lead screw B601 to rotate in the horizontal direction.

[0057] The elastic telescopic component 604 includes a cylinder 6041 and a rod 6042. One end of the rod 6042 extends into the cylinder 6041 and slides with the cylinder 6041. An elastic element B (not shown in the figure) is provided inside the cylinder 6041. The elastic element B is fixedly connected to the cylinder 6041 and the rod 6042. The rod 6042 is fixedly connected to the push plate C603. The cylinder 6041 passes through the push plate A602 and is fixedly connected to the push plate A602. The purpose of this arrangement is to use the elastic element B to flexibly support the rod 6042, so that the push plate C603 can move linearly in the horizontal direction relative to the push plate A602 when subjected to external thrust.

[0058] The transmission assembly C9 includes a rotating shaft J901, a worm gear pair B902, and a transmission pair D903. The rotating shaft J901 is rotatably connected to the device body 1. The rotating shaft J901 is connected to the lead screw B601 via the worm gear pair B902. The rotating shaft J901 is connected to the rotating shaft H703 via the transmission pair D903. The rotating shaft H703 drives the rotating shaft J901 to rotate horizontally via the transmission pair D903. The rotating shaft J901 drives the lead screw B601 to rotate horizontally perpendicular to the rotation axis of the rotating shaft J901 via the worm gear pair B902. The purpose of this arrangement is to drive the lead screw B601 to rotate horizontally, that is, to convert the rotational motion of the rotating shaft H703 into the rotational motion of the lead screw B601 on the horizontal wire feeding chute.

[0059] The rotating shaft H703 drives the rotating shaft J901 to rotate horizontally through the transmission pair D903. The rotating shaft J901 drives the lead screw B601 to rotate horizontally through the worm gear pair B902. The lead screw B601 pushes the push plate A602 to move linearly horizontally along its own length. The push plate A602 pushes the push plate C603 to move synchronously through the elastic telescopic component 604. At this time, the hot melt plate 606 located on the push plate C603 achieves the technical effect of sealing the continuous roll sealing gasket by contacting the continuous roll bag against the surface of the device body 1 and hot melting it.

[0060] Specifically, the hot-melt mechanism 6 is equipped with a cutting assembly for cutting the continuous roll sealing tape. The cutting assembly includes a cutting blade 605, a through groove A (not shown in the figure), and a through groove B (not shown in the figure). The through groove A is formed on the push plate C603, and the through groove B is formed on the device body 1. The cutting blade 605 is detachably connected to the push plate A602, and the cutting blade 605 is used in conjunction with the through grooves A and B. When the push plate C603 drives the hot-melt plate 606 to press against the continuous roll bag for hot-melt sealing, the push plate A602 continues to move linearly and uses the elastic telescopic component 604 to push the push plate C603 to drive the hot-melt plate 606 to continuously press against the continuous roll bag. At this time, the push plate A602 drives the cutting blade 605 to sequentially pass through the through grooves A and B to cut the continuous roll bag, and cut and separate the sealed bag from the continuous roll bag.

[0061] Specifically, the cutting blade 605 is detachably connected to the push plate A602 via a bolt assembly. Those skilled in the art should understand that in this embodiment, the purpose of connecting the cutting blade 605 to the push plate A602 using a bolt assembly is to confine the cutting blade 605 to the push plate A602 and facilitate subsequent replacement of the cutting blade 605 by relevant technicians. Therefore, in some embodiments, the cutting blade 605 can also be connected to the push plate A602 by a snap-fit ​​method. Furthermore, those skilled in the art should understand that the cutting blade 605 can also be fixedly connected to the push plate A602 by welding.

[0062] Specifically, the flaring mechanism 8 includes a lever 801 and a rotating shaft I802. The lever 801 is sleeved on and fixedly connected to the rotating shaft I802. The rotating shaft I802 is rotatably connected to the device body 1. The mechanism also includes:

[0063] The transmission component D is connected to the hot melt mechanism 6 and is used to drive the rotating shaft I802 to rotate in the horizontal direction;

[0064] The transmission assembly D includes a push rod 803, a rotating cylinder 804, and a transmission pair C805. One end of the push rod 803 extends into the rotating cylinder 804 and slides with it. The push rod 803 is fixedly connected to the push plate A602 and passes through the push plate C603. The rotating cylinder 804 is rotatably connected to the device body 1 and is driven by the rotating shaft I802 through the transmission pair C805. A push column (not shown in the figure) is fixedly connected to the push rod 803. The rotating cylinder 804 has a spiral groove A (not shown in the figure), a spiral groove B (not shown in the figure), a linear groove (not shown in the figure), and a transition groove (not shown in the figure). The two spiral grooves have opposite spiral directions and are connected through the transition linear groove (not shown in the figure). The spiral groove B is connected through the linear groove. The push column slides with the spiral groove A, spiral groove B, linear groove, and transition groove. Push plate A602 pushes push rod 803 to slide along rotating cylinder 804, and pushes push column to slide sequentially along spiral groove A, transition groove, spiral groove B, and linear groove. During this process, when push column passes spiral groove A, rotating cylinder 804 rotates forward relative to push rod 803; when push column passes spiral groove B, rotating cylinder 804 rotates reverse relative to push rod 803; when passing linear groove, rotating cylinder 804 stops rotating relative to push rod 803. At this time, firstly, rotating cylinder 804 drives lever 801 to rotate forward through transmission pair C805. Lever 801 is inserted into the retrieval bag to support both sides of the retrieval bag and stretch it flat for sealing by the heat fusion assembly. Secondly, rotating cylinder 804 drives lever 801 to rotate reverse through transmission pair C805, turning lever 801 out of the retrieval bag. At this time, cutting blade 605 in cutting assembly abuts against the retrieval bag. The purpose of this setting is to stretch the retrieval bag flat and prevent wrinkles from forming during sealing, which would lead to sealing failure.

[0065] Specifically, a filter plate 10 is embedded in the device body 1, and the filter plate 10 is detachably connected to the device body 1 by a bolt assembly.

[0066] In this embodiment of the invention, a person skilled in the art installs the continuous roll-up bag on the mounting assembly 2, passes one end through the outlet assembly 4, and leads it out of the device body 1. At this time, the motor 301 drives the rotating shaft B302 to rotate through the transmission pair A304. The rotating shaft B302 drives the fan blade 303 to rotate, causing the device body 1 to form a negative pressure with the external environment. At the same time, the motor 301 drives the rotating shaft F701 to rotate horizontally through the transmission assembly A704. The rotating shaft F701 drives the incomplete gear 705 to rotate synchronously. The rotating incomplete gear 705, the spur gear B707 fixedly connected to the rotating shaft G702, and the spur gear fixedly connected to the rotating shaft H703 are all connected to the rotating shaft. A706 engages alternately. At this time, rotating shaft G702 drives rotating shaft C401 to rotate horizontally via a coupling. Rotating shaft C401, through gear pair 403, drives rotating shaft D402 to rotate horizontally in the opposite direction to rotating shaft C401. Simultaneously, the two flexible sleeves 404, through their opposite rotational movements, cause the continuous roll-up retrieval bag outlet device body 1 located between them to be propelled. The negative pressure generated by the opening assembly 3 draws air into the retrieval bag, causing it to open for technicians to place the specimen. Meanwhile, rotating shaft H703 drives rotating shaft J901 to rotate horizontally via transmission pair D903. The worm gear pair B902 drives the lead screw B601 to rotate horizontally. The lead screw B601 pushes the push plate A602 to move linearly horizontally along its length. The push plate A602 pushes the push plate C603 to move synchronously through the elastic telescopic component 604. At this time, the hot melt plate 606 on the push plate C603 presses the continuously rolled bag against the surface of the device body 1 and performs a hot melt sealing treatment on it. At the same time, the push plate A602 pushes the push rod 803 to slide along the rotating cylinder 804, and pushes the push column to slide sequentially along the spiral groove A, the transition groove, the spiral groove B, and the linear groove. During this process, when the push column passes through the spiral groove A, the rotating cylinder 804 is relatively... When push rod 803 rotates forward, and push column passes through spiral groove B, rotating cylinder 804 rotates in reverse relative to push rod 803. When passing through linear groove, rotating cylinder 804 stops rotating relative to push rod 803. At this time, firstly, rotating cylinder 804 drives lever 801 to rotate forward through transmission pair C805. Lever 801 is inserted into the retrieval bag to support both sides of the retrieval bag and stretch it flat for sealing by the heat fusion assembly. Secondly, rotating cylinder 804 drives lever 801 to rotate in reverse through transmission pair C805, turning lever 801 out of the retrieval bag. At this time, cutting blade 605 in cutting assembly cuts the continuous retrieval bag by contacting it, achieving the technical effect of immediate filling and sealing of the retrieval bag.

[0067] Please see Fig. 1 , Fig. 2 as well as Fig. 5As an embodiment of the present invention, the device body 1 is provided with an introduction mechanism 5 for timely introduction of specimens into a continuous roll-up bag. The introduction mechanism 5 includes a lead screw A502, a guide plate 503, and a placement box (not shown in the figure). The placement box is fixedly connected to the device body 1, the lead screw A502 is rotatably connected to the placement box, the guide plate 503 is threadedly connected to the lead screw A502, the guide plate 503 is slidably engaged with the placement box, and the pushing part on the guide plate 503 is slidably engaged with the guide groove (not shown in the figure) opened on the placement box. The device also includes:

[0068] The transmission component E is connected to the rotating shaft H703 and is used to drive the lead screw A502 to rotate in the horizontal direction.

[0069] The transmission assembly E includes a rotating shaft E501, a worm gear pair A504, and a transmission pair B505. The rotating shaft E501 is rotatably connected to the placement box. The rotating shaft E501 is connected to the lead screw A502 through the worm gear pair A504. The rotating shaft E501 is connected to the rotating shaft H703 through the transmission pair B505.

[0070] Specifically, the placement box is connected to the device body 1 by welding or integral molding. Those skilled in the art should know that the purpose of this arrangement is to confine the placement box to the device body 1. Therefore, in some embodiments, the placement box can also be detached and connected to the device body 1 by bolt assembly.

[0071] Specifically, the guide plate 503 is generally T-shaped or 7-shaped.

[0072] In this embodiment of the invention, the rotating shaft H703 drives the rotating shaft E501 to rotate horizontally via the transmission pair B505. The rotating shaft E501 drives the lead screw A502 to rotate horizontally with its axis of rotation perpendicular to the axis of rotation of the rotating shaft E501 via the worm gear pair A504. The lead screw A502 pushes the guide plate 503 to move linearly along its own length direction and pushes out the specimen (which can be a permanent slide specimen) located in the placement box through its own pushing part. The specimen falls into the opened retrieval bag in the above example under its own gravity for sealing. The purpose of this setting is to achieve the technical effect of immediate specimen loading and sealing in conjunction with the above example. At the same time, it can avoid the retrieval bag being empty due to asynchronous actions when the specimen is placed manually. It can also avoid the staff being burned by the heat-sealing mechanism 6 when the retrieval bag is sealed.
