DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0031] like Figure 1-Figure 7 As shown, a drug mixing device proposed in one embodiment of the present application includes:

[0032] A mounting shell 1 is provided with a feed frame 5, one side of the mounting shell 1 is connected with a mixing cylinder 6, the bottom end of the mixing cylinder 6 is open and a containing container 7 is installed thereon, and one side of the containing container 7 is provided with a liquid inlet 14;

[0033] The grinding mechanism comprises two transmission rods 2 rotatably mounted in the mounting shell 1, the two transmission rods 2 are both mounted with synchronous wheels 3, a synchronous belt 4 is installed between the two synchronous wheels 3, and a grinding belt 13 is sleeved on the outer surface of the synchronous belt 4, one end of one of the transmission rods 2 is located outside the mounting shell 1 and is mounted with a knob;

[0034] Among them, a slot 15 is provided on one side of the feeding frame 5 close to the mixing cylinder 6, the grinding belt 13 is located in the mounting shell 1 and the upper horizontal surface is in contact with the feeding frame 5, the mounting shell 1 is made of transparent material and a scale 16 is provided on the outer side, when the tablet is located in the feeding frame 5, the tablet is in contact with the upper horizontal surface of the grinding belt 13;

[0035] The mixing mechanism 8 comprises a mixing rod 801 vertically and rotatably mounted in the mixing barrel 6, and a driving member 802 for driving the mixing rod 801 to rotate is mounted on the mounting shell 1;

[0036] The elastic abutment 9 is mounted on the mounting shell 1. When the tablet is in the feed frame 5, the elastic abutment 9 makes the tablet elastically abut against the horizontal surface of the grinding belt 13. When in use, first place the tablet on the feed frame 5, then turn the knob to make the grinding belt 13 Figure 3As shown, it moves clockwise, so that the tablet fits on one side of the feed frame 5, and then the elastic resistance piece 9 makes the tablet resist on the horizontal plane of the grinding belt 13. At this time, the scale 16 is just aligned with the tablet, and then the knob is turned clockwise to rotate one of the transmission rods 2. The rotation of the transmission rod 2 can rotate the synchronous wheel 3 installed thereon. The rotation of the synchronous wheel 3 will cause another synchronous wheel 3 to rotate through the synchronous belt 4, and the grinding belt 13 will be driven to move when the synchronous belt 4 moves. Because the tablet is resisted on the grinding belt 13 through the elastic resistance piece 9 at this time, the bottom end of the tablet will be polished as the grinding belt 13 moves, and then the tablet will be ground into powder. As the tablet is ground, The graduated scale 16 can intuitively show the thickness of the ground tablet, so that the amount of ground powder can be known. After the powder is ground, the tablet is taken out. Because the tablet is not broken, it is convenient to retain the tablet later. After the tablet is taken out, the transmission rod 2 can be rotated in the reverse direction to make the grinding belt 13 rotate counterclockwise, so as to move the powder on the grinding belt 13 and make the powder pass through the groove 15 and fall into the mixing barrel 6. At this time, water or liquid medicine can also be poured into the liquid inlet 14, and the mixing rod 801 is rotated by the driving member 802 to mix the powder and the liquid medicine. Compared with the prior art, it is convenient to control the amount of ground powder, and there is no need to break the tablet, so it is convenient to retain the tablet later.

[0037] like Figure 3 As shown, in some embodiments, the driving member 802 acts on another transmission rod 2. When the transmission rod 2 rotates, the driving member 802 drives the mixing rod 801 to rotate continuously in one direction. That is to say, when multiple types of liquid medicines need to be mixed, the liquid medicines can be poured into the mixing barrel 6 in advance, so that the liquid medicines can be mixed when the tablets are ground. Not only that, when the knob is turned, the mixing rod 801 can also be driven to rotate, and no additional driving force is required to drive the mixing rod 801 to rotate.

[0038] like Figure 3 and Figure 7As shown, in some embodiments, the driving member 802 includes a rotating rod 8021 rotatably mounted on the mounting shell 1, and a pulley 8022 is mounted on the rotating rod 8021 and the mixing rod 801, and a transmission belt 8023 is installed between the two pulleys 8022. A movable frame plate 8024 is horizontally slidably mounted on the mounting shell 1, and a movable groove 8025 is vertically opened on the movable frame plate 8024. One end of another transmission rod 2 is located outside and is installed with a connecting ring 8026, and a column 8027 is constructed on the connecting ring 8026 to be tangential to the movable groove 8025 in a sliding manner. The movable frame plate 8024 is connected to the transmission belt 8023. When the transmission rod 2 When rotating, the connecting ring 8026 will be driven to rotate. Since the connecting ring 8026 is connected to the column rod 8027, the column rod 8027 will also rotate at this time. Since the column rod 8027 slides tangentially in the movable groove 8025, the continuous rotation of the connecting ring 8026 will cause the movable frame 8024 to reciprocate horizontally. When the movable frame 8024 reciprocates, the movement of the movable frame 8024 will drive the transmission belt 8023 connected thereto to move. The movement of the transmission belt 8023 will cause the pulley 8022 to rotate. As the pulley 8022 rotates, it will drive the mixing rod 801 to rotate to achieve stirring of the mixing rod 801.

[0039] like Figure 3 and Figure 7 As shown, in some embodiments, in order to further improve the mixing effect and realize the continuous unidirectional rotation of the mixing rod 801, two wedge rods 8028 are horizontally slidably installed on the movable frame plate 8024, and the two wedge rods 8028 are located in the transmission belt 8023. A resistance spring 8029 is installed between the wedge rods 8028 and the movable frame plate 8024. A plurality of wedge grooves 80210 for inserting between the wedge rods 8028 are arranged in a linear array on two mutually parallel surfaces on the inner side of the transmission belt 8023. The inclined surfaces of the wedge-shaped grooves 80210 on the two parallel surfaces are in opposite directions. It should be noted that the friction force between the pulley 8022 and the belt is greater than the elastic force of the resisting spring 8029. When the movable frame 8024 moves, the inclined surface of one of the wedge-shaped plates contacts the inclined surface of the wedge-shaped groove 80210, and the plane of the other wedge-shaped plate contacts the plane of the wedge-shaped groove 80210 in the corresponding direction. In this way, the movable frame 8024 can realize the unidirectional rotation of the mixing rod 801 when it moves horizontally back and forth, thereby further improving the working efficiency.

[0040] like Figure 3As shown, in some embodiments, the elastic resistance member 9 includes a driving plate 901 rotatably mounted on the mounting shell 1, the driving plate 901 has an arc-shaped structure with an arc-shaped top plate 902, the feed frame 5 is arc-shaped and coaxial with the arc-shaped top plate 902, the arc-shaped top plate 902 is slidably inserted into the feed frame 5, and an arc-shaped slide plate 903 is slidably inserted at one end of the arc-shaped top plate 902 located in the feed frame 5, and one end of the arc-shaped slide plate 903 is configured with a pressing plate 904 that fits the inner side of the feed frame 5, and the arc-shaped slide plate 903 and the arc-shaped top plate 902 are slidably inserted into the feed frame 5. A compression spring 905 is installed between the top plates 902, and a limiting member 10 is installed on the feed frame 5 for releasing the limit or limiting the movement of the arc-shaped top plate 902. That is to say, when the tablets are poured into the feed frame 5, the arc-shaped top plate 902 is rotated so that the compression plate 904 is pressed on the tablets, and then the arc-shaped top plate 902 is further moved to compress the compression spring 905. At this time, the compression plate 904 is in contact with the tablets, and then the arc-shaped top plate 902 can be limited by the limiting member 10, which is convenient to use.

[0041] like Figure 3 and Figure 6 As shown, in some embodiments, the limiting member 10 includes a convex plate 1001 constructed on the arc-shaped top plate 902, the convex plate 1001 is constructed with an arc-shaped mounting plate 1002 coaxial with the arc-shaped top plate 902, the arc-shaped mounting plate 1002 is constructed with a mounting cylinder 1003, a wedge-shaped plug plate 1004 is slidably mounted on the mounting cylinder 1003, a tightening spring 1005 is installed between the wedge-shaped plug plate 1004 and the mounting cylinder 1003, and a plurality of wedge-shaped slots 1006 for inserting the wedge-shaped plug plate 1004 are provided in an arc-shaped array on the outer peripheral side of the arc-shaped top plate 902, that is, it is only necessary to move the arc-shaped top plate 902 so that the arc-shaped top plate 902 moves forward. When the arc top plate 902 moves in the feed frame 5, when the clamping plate 904 is pressed on the tablet, because when the arc top plate 902 moves toward the feed frame 5, the inclined surface of the wedge-shaped slot 1006 contacts the inclined surface of the wedge-shaped insert plate 1004, it does not affect the movement of the arc top plate 902 toward the feed frame 5, and plays a one-way limiting role. When the arc top plate 902 needs to be moved away from the feed frame 5, only the wedge-shaped insert plate 1004 needs to be moved. When grinding tablets, if the resistance force is not enough, this design only needs to continue moving the arc top plate 902 to make the wedge-shaped insert plate 1004 move to another wedge-shaped slot 1006. It is easy to use and can quickly limit.

[0042] like Figure 3 As shown, in some embodiments, the containing container 7 includes a threaded cylinder 701 screwed into the bottom end of the mixing cylinder 6, and the bottom end of the threaded cylinder 701 is configured with an annular plate 703, and the annular plate 703 is installed with a nipple 702, that is to say, the mixed liquid medicine will be located in the nipple 702 in this embodiment, because the nipple 702 can only when the newborn generates negative pressure by sucking with the mouth, the mixed liquid inside the nipple 702 can enter the newborn's mouth, so as to facilitate the feeding of medicine to the newborn.

[0043] like Figure 3 As shown, in some embodiments, a sealing plate 705 is horizontally slidably inserted on one side of the annular plate 703, and an adjusting screw 704 is horizontally and rotatably installed on the annular plate 703. The sealing plate 705 is threadedly sleeved on the adjusting screw 704. That is to say, when mixing is performed, the sealing plate 705 blocks the bottom of the annular plate 703, and the medicine is located inside the annular plate 703. This can effectively prevent the medicine from seeping out of the liquid outlet of the nipple 702 when mixing the medicine.

[0044] like Figure 3 As shown, in some embodiments, a guide plate 11 is inclined inside the mounting shell 1, the top end of the guide plate 11 is in contact with the grinding belt 13, a powder feed slot 12 connected to the mounting shell 1 is provided on the mixing barrel 6, and the lowest end of the guide plate 11 is connected to the lowest end of the powder feed slot 12. The inclined design of the guide plate 11 can effectively scrape off the powder on the grinding belt 13 and can effectively introduce the powder into the mixing barrel 6.

[0045] like Figure 3 As shown, in some embodiments, the grinding belt 13 is a nylon sanding belt, which is more durable and produces less debris during grinding.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
