Description

Technical Field

[0001] This utility model relates to the field of veterinary drug production equipment technology, specifically to a molding device for rapid molding of veterinary drug granules. Background Technology

[0002] In the field of veterinary drug production, granules have become one of the most common dosage forms due to their advantages such as easy storage, easy administration, and rapid absorption. Extrusion granulation is an important process for forming veterinary drug granules and is widely used in actual production. This method first mixes raw materials and binders to form a soft material, which is then extruded into strips by an extruder and cut into granules of a specified length by a cutting device.

[0003] Current veterinary drug granule extrusion molding devices generally have a structure similar to that described in patent application CN220159907U, which discloses a forging press for aluminum plate processing. This includes a storage bin and an annular baffle. The storage bin contains a cover plate, a stirring shaft, and stirring blades. The annular baffle contains a rotating assembly and multiple forming cylinders. One of the forming cylinders has a hydraulic telescopic rod and a pressure plate above it, and a rotating block and a cutter below it. However, the granules cut by this invention tend to stick together when they fall, requiring subsequent screening and granulation processes for processing. This not only leads to the loss of raw materials but also increases production costs.

[0004] Therefore, this utility model proposes a molding device for rapid molding of veterinary drug granules to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a molding device for rapid molding of veterinary drug granules, which solves the problem in the prior art where the cut granules easily stick together when they fall, resulting in not only the loss of raw materials but also increased production costs.

The inlet and outlet of the collection box are staggered, and a vibration motor is connected to the bottom of the collection box.

[0009] Furthermore, a pusher block is connected inside the collection box, and the end of the pusher block is connected to the drive shaft of a second drive cylinder, which is connected to the frame.

[0010] Furthermore, the mixing auger includes a mixing tank, an auger shaft, and spiral blades connected to the auger shaft. Both ends of the auger shaft are mounted on the mixing tank via bearing seats, and the discharge port on the mixing tank is connected to the feed port of the conveying auger.

[0013] Furthermore, a rubber shock-absorbing pad is connected to the bottom of the frame, and a shock-absorbing spring is connected between the granulator and the rubber shock-absorbing pad.

[0014] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model can spray an anti-sticking agent through an atomizing nozzle during cutting, thereby avoiding adhesion caused by surface stickiness, reducing raw material loss, and improving the yield.

[0016] 2. The humidity sensor inside the conveying auger of this utility model can monitor the humidity of the material in real time, and then the steam nozzle automatically adjusts the amount of steam injected according to the feedback, so that the humidity of the material is kept within the optimal forming range, avoiding excessive dryness and cracking or excessive wetness and sticking.

[0017] 3. This utility model uses spiral blades to compress and mix raw materials, and the vibration of the vibrating motor and the mechanical extrusion of the pusher block increase the rate of air bubble discharge from the material, thereby reducing the cost of particle breakage caused by air bubble rupture during cutting.

[0025] like Figure 1-4 As shown, a molding device for rapid molding of veterinary drug granules includes a mixing auger, a conveying auger connected to the discharge port of the mixing auger, and a granulator connected to the discharge port of the conveying auger. The granulator includes a frame 1, a first drive cylinder 2 and a material cylinder 3 connected to the frame 1, a rubber shock-absorbing pad 4 connected to the bottom of the frame 1, and a shock-absorbing spring 5 connected between the granulator and the rubber shock-absorbing pad 4. The piston rod end of the first drive cylinder 2 is connected to an extrusion block, which slides inside the material cylinder 3. The discharge end of the material cylinder 3 is detachably connected to a flat die 7, which has multiple extrusion forming holes evenly distributed on it. A cutting blade 8 is provided on the surface of the flat die 7, and the cutting blade 8 is mounted on the material cylinder 3 via a blade holder 9. A drive motor 10 is also connected to the blade holder 9, and the drive motor 10 drives the cutting blade 8 to rotate. A feeding box 11 is provided at the discharge end of the material cylinder 3, and a feeding port is provided at the bottom of the feeding box 11. An atomizing nozzle 12 is connected inside the feeding box 11, and the atomizing nozzle 12 is connected to an anti-adhesion spray pressure tank 13 via a connecting pipe 27.

[0026] Furthermore, a defoaming component is provided between the material cylinder 3 and the mixing auger. The defoaming component includes a collection box 14, the outlet of which is connected to the material cylinder 3, and the inlet of which is connected to the outlet of the mixing auger. The inlet and outlet of the collection box 14 are staggered. A vibration motor 15 is connected to the bottom of the collection box 14. A pusher block 16 is connected inside the collection box 14. The end of the pusher block 16 is connected to the drive shaft of a second drive cylinder 17, which is connected to the frame 1.

[0027] Furthermore, the mixing auger includes a mixing tank 18, an auger shaft 19, and spiral blades 20 connected to the auger shaft 19. Both ends of the auger shaft 19 are mounted on the mixing tank 18 via bearing seats. The discharge port on the mixing tank 18 is connected to the feed port of the conveying auger.

[0029] First, the mixing auger recompresses and mixes the already mixed raw materials using spiral blades 20. The screw pitch gradually decreases along the discharge direction, gradually increasing material density and reducing internal air bubble formation during transport. The material then enters the conveying auger through the discharge port of the mixing tank 18. A humidity sensor 24 inside the auger monitors the material's humidity in real time, and the steam nozzle 25 automatically adjusts the amount of steam injected based on feedback, maintaining the material's humidity within the optimal forming range to prevent excessive dryness and breakage or excessive wetness and sticking. After entering the collection box 14 of the defoaming component, the vibrating motor 15 activates... High-frequency vibration causes bubbles to rise and be expelled. The second drive cylinder 17 pushes the material down, further compacting the material and breaking up residual bubbles. The material then enters the granulator cylinder 3. The first drive cylinder 2 drives the extrusion block to extrude the material through the extrusion holes of the flat die 7 into a strip shape. Then, the cutting blade 8 is driven by the drive motor 10 to rotate at high speed, cutting the strip-shaped material into granules. During the cutting process, the atomizing nozzle 12 sprays an anti-adhesion agent simultaneously, which forms an isolation film on the surface of the granules. The rubber shock-absorbing pads 4 and shock-absorbing springs 5 ​​at the bottom of the frame 1 can absorb the vibration of the device during operation.
