Description

Technical Field

[0001] The utility model relates to the technical field of medicine processing, in particular to a medicine vacuum sealing machine. Background Art

[0002] In order to protect the integrity, stability and safety of drugs, as well as to facilitate storage, transportation and sales, pharmaceutical packaging is used to protect drugs. Usually, glass bottles, plastic bottles, blisters, strips, aluminum tubes, prefilled syringes, medicinal plastic bags, composite materials, etc. are used for packaging.

[0003] At present, sheet-shaped medicines are mostly made of a combination of hard PVC and aluminum foil, which takes advantage of the high barrier properties of aluminum foil and the good formability of other materials to form a double protection for medicine packaging. When using hard PVC materials, it is not easy to split the plate-shaped tablets into single tablets for carrying. At the same time, when tearing the aluminum foil at the single-piece medicine, the aluminum foil is sometimes easily torn to the adjacent tablets by mistake, causing the adjacent tablets to lose their sealed and clean packaging environment, which will also affect the efficacy of the medicines during long-term storage. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a medicine vacuum sealer to solve the problem that when tearing the aluminum foil at a single medicine piece, the aluminum foil is sometimes easily torn to adjacent tablets by mistake, resulting in the adjacent tablets losing their seal and clean packaging environment.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a medicine vacuum sealing machine, comprising:

[0006] A conveying platform, wherein a conveying groove for conveying aluminum foil is provided in the middle of the conveying platform;

[0007] A plurality of negative pressure suction heads, the negative pressure suction heads pass through the side wall of the conveying platform and are connected with the conveying groove, and the negative pressure suction heads are fixedly connected with the conveying platform;

[0008] A clamping plate capable of vertical lifting and lowering, the clamping plate is vertically opposite to the conveying groove, and the clamping plate is located between a plurality of negative pressure suction heads; a plurality of clamping strips are protruding and fixedly provided on the lower surface of the clamping plate;

[0009] Intermittent conveying unit for intermittently conveying aluminum foil.

[0010] The technical principle of the utility model is that the conveying groove can limit the upper aluminum foil and the lower aluminum foil. When the upper aluminum foil and the lower aluminum foil with tablets are moved to the pressing plate driven by the intermittent conveying unit, the negative pressure suction head can suck the air between the upper aluminum foil and the lower aluminum, so that the upper aluminum foil and the lower aluminum directly form a vacuum. At this time, a plurality of pressing strips can compress the upper aluminum foil and the lower aluminum foil, and a plurality of pressing strips can separate and package a plurality of tablets. Finally, the medicines after packaging are formed into an independent vacuum space, so that the storage of tablets is more effective and not affected by the air environment.

[0011] At the same time, when the tablets are cut and carried separately, it is only necessary to tear the upper aluminum foil and the lower aluminum foil along the compression point of the compression strips on the upper aluminum foil and the lower aluminum foil. The tearing of the upper aluminum foil and the lower aluminum foil is convenient and efficient, and it is convenient to carry a single tablet separately.

[0012] Furthermore, a plurality of grooves for positioning tablets are vertically arranged on the inner wall of the conveying groove of the conveying platform, and a liftable punching rod is vertically arranged opposite to the groove of the conveying platform.

[0013] Through the above arrangement, the punching rod can cooperate with the groove, so that the lower aluminum foil between the conveying groove and the punching rod forms an arc under the punching of the punching rod, which is convenient for limiting the position of the tablets, so that the tablets on the lower aluminum foil will not slip during the conveying process, reducing the possibility of packaging errors.

[0014] Furthermore, a toothed blade for forming a tear line on the aluminum foil is fixedly provided on a side of the pressing plate away from the punching rod.

[0015] Through the above arrangement, the toothed blade slightly cuts the upper aluminum foil and the lower aluminum foil along the positions where the compression strips are pressed, so that a tear line is formed at the compressed position of the upper aluminum foil and the lower aluminum foil, which is convenient for tearing a single tablet along the tear line and carrying it alone or in multiple pieces, and is less likely to cause tearing errors.

[0016] Furthermore, it also includes a support frame with an inverted "U"-shaped longitudinal cross-sectional profile, both ends of the support frame are fixedly connected to the top surface of the conveying platform, the lower inner wall of the support frame smoothly transitions with the inner wall of the conveying groove of the conveying platform, and the clamping plate and the punching rod are both installed on the lower side of the middle part of the support frame.

[0017] Through the above arrangement, the support frame can support the installation and lifting of the pressing plate and the punching rod, so that the installation of the pressing plate and the punching rod is more stable.

[0018] Furthermore, a guide groove for guiding and conveying the upper aluminum foil is vertically penetrated through the middle of the support frame.

[0019] Through the above arrangement, the guide groove can guide the upper aluminum foil so that the upper aluminum foil can be stably pressed and fitted with the lower aluminum foil.

[0020] Furthermore, a drug guiding channel is coaxially provided inside the punching rod, a connecting channel connected to the drug guiding channel is provided on the support frame, a bellows connected to the drug guiding channel is vertically fixedly installed on the support frame, and the bellows is connected to a drug inlet valve.

[0021] Through the above arrangement, the punching rod can cooperate with the bellows and the medicine inlet valve. When the punching rod presses the lower aluminum foil into the groove, the medicine inlet valve opens, and the tablets fall from the bellows through the medicine guide channel to the part of the lower aluminum foil located in the groove, which can improve the medicine release efficiency.

[0022] Further, the outer wall of the punching rod is connected to a first lifting unit, and the first lifting unit includes:

[0023] A first hydraulic telescopic rod, the first hydraulic telescopic rod is vertically arranged, and the upper end of the first hydraulic telescopic rod is fixedly connected to the lower side of the middle part of the support frame;

[0024] A clamp with an "8"-shaped longitudinal section, one end of which is coaxially fixedly mounted on an end of the first hydraulic telescopic rod away from the support frame, and one end of which is coaxially fixedly mounted on the outer wall of the punching rod, and a bellows is fixedly connected to the top end of the punching rod through a connecting channel;

[0025] A first hydraulic pump controls the lifting of the first hydraulic telescopic rod, and the first hydraulic pump is fixedly installed on the support frame.

[0026] Through the above arrangement, when controlling the lifting of the punching rod, the first hydraulic pump controls the first hydraulic telescopic rod to extend or shorten. At this time, the clamp drives the punching rod to rise and fall synchronously through the telescopic end of the first hydraulic telescopic rod, so that the punching rod can be stably lifted and lowered in coordination.

[0027] Further, the support frame is connected to a second lifting unit, and the second lifting unit includes:

[0028] A plurality of second hydraulic telescopic rods, the second hydraulic telescopic rods are vertically arranged, the upper ends of the second hydraulic telescopic rods are fixedly connected to the lower side of the middle part of the support frame, and the telescopic ends of the second hydraulic telescopic rods are fixedly connected to the upper end of the pressing plate;

[0029] A second hydraulic pump controls the lifting of the first hydraulic telescopic rod, and the second hydraulic pump is fixedly installed on the support frame.

[0030] Through the above arrangement, a plurality of second hydraulic telescopic rods can drive the clamping plate to vertically rise and fall under the control of the second hydraulic pump, and can accurately complete the clamping operation and the forming of the tear line.
