Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an automatic feeding device for gas-generating medicine raw materials. Background Art

[0002] In the event of a collision, the inflator in a car's airbag detonates to generate gas, inflating the airbag and protecting the passengers. The core component of the inflator's gas production is the gas generating agent. During the production process, the raw material is fed into the extrusion sleeve of an extruder, where it is formed into a strip.

[0003] Currently, the raw materials for gas-producing drugs are mostly fed manually, which requires high labor intensity, produces a large amount of dust during the work process, and cannot guarantee personnel safety. The manual feeding speed cannot be kept stable, which in turn affects the density and consistency of the drugs. If an explosion occurs during the production process, it may cause casualties. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an automatic feeding device for gas-generating medicine raw materials, which can reduce the labor intensity of workers, make the feeding speed more uniform, and improve the consistency of medicines.

The device is special in that: an explosion-proof isolation chamber is provided outside the extruder, which covers the extruder, and the extrusion sleeve extends from one side of the explosion-proof isolation chamber; a linear vibrator is provided at the upper end of the extruder body, and a horizontally arranged linear vibration rail is fixed to the linear vibrator. The linear vibration rail is in the shape of an angle iron, one end of which extends from the other side of the explosion-proof isolation chamber and a feeding funnel is fixed above the outer end of the linear vibration rail. The other end of the linear vibration rail extends above the feeding funnel and is used to guide externally added raw materials into the feeding funnel;

[0007] A vibrating plate is installed on one side of the feed hopper outside the explosion-proof isolation chamber through a support frame. The vibrating plate extends to the top of the feed hopper through the discharge rail and is used to guide the raw materials into the linear vibrating rail.

[0008] A laser ranging sensor is provided above the feeding funnel in the explosion-proof isolation chamber through an inner bracket to detect the height of the material in the feeding funnel.

[0009] As a further preference, a first camera is provided on the inner bracket for monitoring the material condition in the feeding funnel.

[0010] As a further preference, an outer bracket is fixed to the upper end of the outer wall on the other side of the explosion-proof isolation chamber, and a second camera is provided on the outer bracket for monitoring the material situation in the vibration plate.

[0011] As a further preference, an observation window and a display are provided on the outer wall on the other side of the explosion-proof isolation wall. The first camera and the second camera are communicatively connected to the display for displaying the captured video on the display in real time. The observation window is used to observe the vibration of the material on the linear vibration rail.

[0012] As a further preference, an explosion relief port is provided on the top surface of the explosion-proof isolation wall to relieve pressure and prevent casualties.

[0013] As a further preference, a controller and a human-machine interface are interconnected, and the signal output end of the laser ranging sensor is connected to the controller for controlling the actions of the linear vibrator and the vibration disk and performing parameter settings.

[0014] The beneficial effects of the utility model are:

[0015] 1.

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the present invention relates to an automatic feeding device for gas-generating agent raw materials, comprising an extruder 15, preferably a twin-screw extruder, for extruding gas-generating agent granules into strips. A feeding hopper 6 is provided on the extrusion sleeve 8 of the extruder 15. An explosion-proof isolation chamber 1 is located outside the extruder 15. The explosion-proof isolation chamber 1 is comprised of a frame and steel plates secured to the outside of the frame. The explosion-proof isolation chamber 1 encloses the extruder 15 and has an explosion relief port 9 on its top surface to relieve pressure and prevent casualties in the event of a deflagration.

[0021] The extrusion sleeve 8 passes through one side of the explosion-proof isolation chamber 1; a linear vibrator 7 is fixed to the upper end of the extruder body 15, and a horizontally arranged linear vibration rail 5 is fixed on the linear vibrator 7. The linear vibration rail 5 is in the shape of an angle iron, one end of which passes through the other side of the explosion-proof isolation chamber 1 and a feed funnel 18 is fixed on the outer end of the pass-through. The other end of the linear vibration rail 5 extends above the feeding funnel 6, which is used to introduce the added gas-generating drug raw material into the feeding funnel 6;

[0022] A vibrating plate 13 is installed outside the explosion-proof isolation chamber 1 on one side of the feed funnel 18 through a support frame 14. The discharge port of the vibrating plate 13 extends to the top of the feed funnel 18 through a discharge rail 17, which is used to introduce the gas-generating drug raw materials into the linear vibrating rail 5.

[0023] A horizontally arranged inner bracket 2 is welded above the feeding funnel 6 in the explosion-proof isolation chamber 1. A laser ranging sensor 3 is fixed on the inner bracket 2 corresponding to the feeding funnel 6 to detect the material height in the feeding funnel 6. A first camera 4 is also installed on the inner bracket 2 to monitor the material status in the feeding funnel 6.

[0024] An outer bracket 10 is welded to the upper end of the outer wall on the other side of the explosion-proof isolation chamber 1 , and a second camera 11 is fixed on the outer bracket 10 . The second camera 11 points to the vibration plate 13 and is used to monitor the material situation in the vibration plate 13 .

[0025] A rectangular observation port is provided on the outer wall on the other side of the explosion-proof isolation wall, and a transparent observation window 12 is installed within the port for observing the vibration of the material on the linear vibration track 5. A display 16 is installed below the observation window 12 on the outer wall on the other side of the explosion-proof isolation wall. The first camera 4 and the second camera 11 are in communication with the display 16 for displaying the captured video in real time on the display 16.

[0026] The device is also provided with a controller and a human-machine interface (not shown in the figure) which are interconnected. The signal output end of the laser ranging sensor 3 is connected to the signal input end of the controller for controlling the action of the linear vibrator 7 and the vibration disk 13 and performing parameter setting.

[0027] When working, the power switch of the equipment is turned on to power on the equipment. The operator adds a certain amount of crushed gas-generating drug material to the vibration plate 13 and sets various parameters of the gas-generating drug production on the human-machine interface.

[0028] When the vibration plate 13 is switched on, it begins vibrating. The material particles, driven by the vibration of the vibration plate 13, pass through the discharge rail 17 at the discharge port of the vibration plate and enter the feed hopper 18. Under the vibration of the linear vibrator 7, the linear vibrating rail 5 continuously feeds the material particles into the feeding hopper 6. The material particles are then extruded into strips of gas-producing agent by the screw in the extruder 15. During feeding, when the material level in the feeding hopper 6 exceeds the set value, the laser ranging sensor 3 transmits a signal to the controller, which controls the vibration plate 13 and the linear vibrator 7 to stop working, thus completing a working cycle. When the material level in the feeding hopper 6 falls below the set value, the laser ranging sensor 3 transmits a signal to the controller, which controls the vibration plate 13 and the linear vibrator 7 to start working, continuously feeding the material particles into the feeding hopper 6.

[0029] During the production process, the material conditions in the feeding hopper 6 and the vibration plate 13 can be monitored at any time through the first camera 4, the second camera 11 and the display 16, which can reduce the workload and ensure the safety of workers.

[0030] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
