Description
Technical field
This utility model relates to a kind of pharmaceutical machine, is specifically related to a kind of medical membrane machine of Chinese medicine plaster pressing with double cylinders.
Background technology
The Chinese medicine plaster is the external used medicine dosage form of using always, and the method that making Chinese medicine plaster generally adopts in large-scale industrial production is: mix with natural rubber after medical material being broken into fine powder or extraction earlier, rescud is coated onto to dry to cut on the base cloth and forms.And compound Nanxing pain paste is that to have adopted its medicine film of novel process be the medical material fine powder to be mixed the back adopt medical membrane machine to make with substrate.No. 03131514.3 patent of invention of China discloses a kind of medical membrane machine, and the structure of this medical membrane machine is: the horizontal screw bolt extruder is housed on frame; The rear end of this screw extruder with communicate with pressing cylinder outlet; The front end of screw extruder is provided with die head, and the front portion of this die head is downward horn mouth, forms flat medicine film outlet down; Being set to of screw thread on the screw rod of described screw extruder: before the pitch close back dredge, the dark reducing-pitch thread in shallow back before the depth of thread.This technical scheme has solved the automated production problem of continuous medicine film, can realize the automated production in enormous quantities of Chinese medicine plaster.When but it is produced, be that medical membrane machine must be shut down wait when adopting single cylinder to feed in raw material each feeding in raw material, work rhythm is slower; Simultaneously, the width of this medical membrane machine die head is limited, and the width that simply strengthens die head can produce the uneven phenomenon of drug, and therefore the coating width of this medical membrane machine ointment also is restricted; So the efficient of this medical membrane machine still remains further to be improved.
The utility model content
At the above-mentioned deficiency of prior art, the purpose of this utility model is that above-mentioned medical membrane machine is improved, and a kind of medical membrane machine of pressing with double cylinders is provided.The medical membrane machine of pressing with double cylinders of the present utility model will meet the Chinese medicine plaster more.
The scheme of finishing above-mentioned utility model task is: a kind of medical membrane machine of pressing with double cylinders, be equipped with screw extruder on frame; The rear end of this screw extruder with communicate with pressing cylinder outlet; The front end of screw extruder is provided with die head, and the front portion of this die head is downward horn mouth, forms flat medicine film outlet down; Being set to of screw thread on the described screw extruder screw rod: before the pitch close back dredge, the dark reducing-pitch thread in shallow back before the depth of thread, it is characterized in that, described pressing cylinder is two pressing cylinders that are set up in parallel, the outlet of these two pressing cylinders is respectively equipped with the not gate control valve, and communicate with screw extruder by this not gate control valve respectively, described not gate control valve is controlled by pneumatic element, and connects according to following job order: the A control valve is opened when pneumatic switch upwards draws, the B control valve closes; The B control valve is opened on time downwards, the A control valve closes when pneumatic switch.The further improvement of such scheme, following prioritization scheme is arranged: the width of screw extruder die head strengthens, increase to 12 centimetres by 6 centimetres, the inside of this screw extruder die head is provided with the uniform flow structure simultaneously, this uniform flow structure is: be provided with the shunting island in the drug channel in the die head, Fig. 2 is seen in the position on this shunting island.During work, the outlet of two pressing cylinders provides ointment to screw extruder in turn by the not gate control valve, and the work efficiency of screw extruder is increased substantially, and is provided with the broad die head of uniform flow structure, can improve application width.
Because the present invention adopts two pressing cylinders and works respectively by not gate control valve control pressing cylinder A, B, the ingenious automated production that has solved continuous medicine film after therefore connecing with the follow-up equipment street, can realize the automated production in enormous quantities of Chinese medicine plaster at an easy rate.The present invention is simple in structure, and is economical and practical.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is for being provided with the sketch map on shunting island in the die head.
The specific embodiment
Embodiment 1: the medical membrane machine of present embodiment is equipped with horizontal screw bolt extruder 2 as shown in Figure 1 on frame 8.The screw rod end support of this screw extruder 2 and is fixedlyed connected with synchronizing jugged the wheel in bearing 6.Bearing 6 is installed on the frame 8 by support.The synchronizing jugged wheel by the drivewheel of synchronous cog belt 7 with motor 9 is connected.Motor 9 is fixedly installed in the rear portion of frame 8.The front end of screw extruder 2 is supported on the upright strut.Be shaped on inlet hole on the machine barrel of screw extruder 2 rear ends with the A pressing cylinder 10 that is connected by A not gate control valve 3, B not gate control valve 4, B pressing cylinder 5.This pressing device mainly is made up of A pressing cylinder 10, B pressing cylinder 5 and A cylinder 12, B cylinder 11.The upper end of pressing cylinder is the connector that is convergent awl mouthful shape, and lower end abutment is on the piston of cylinder.The front end of screw extruder 2 is equipped with die head 1.For guarantee by after produce ideal squeezing action forward, be convenient to ointment and form successive medicine film, to be the pitch of thread dredge from preceding close back screw flight, the dark reducing-pitch thread in shallow back before the depth of thread in the present embodiment screw extruder.With reference to Fig. 2: the inside of die head 1 is provided with shunting island 13, adopts island type shunting, uniform flow structure, and front portion be downward horn mouth, cover end cap foremost after, the flat flat medicine film that forms down exports.During use, the medical membrane machine of present embodiment is placed on before the film-making machine, and when the control air valve rose piston in the A cylinder, the ointment in the A pressing cylinder was compressed into the rear end of conveying worm slowly by A not gate control valve.Then, the screw rod in the screw extruder 2 is constantly rotation under the drive of motor 9, and the ointment that enters is wherein passed through reducing-pitch thread compacting gradually, is transported to front end, is finally extruded by die head 1 downward flat outlet.Simultaneously in B pressing cylinder 5, carry out dosing, after the medicine in the A pressing cylinder 10 has been pressed, switch to B pressing cylinder, and so forth by the not gate control valve.In above process, by rational design, all guaranteed the continuous, even and fine and close of medicine film, thereby after not only connecing with the film-making machine street, the automated production in enormous quantities of realization Chinese medicine plaster that can be stable, and experiment showed, since ointment in film forming procedure through pushing, revolve stone roller repeatedly, therefore the film of making of forcing on is easier to bring into play drug effect, and result of use compares the better of traditional method making.In a word, present embodiment obviously reduces labor intensity, increase work efficiency greatly, and the automaticity height, the quality of production is stable, and more helps bringing into play drug effect.
