Description

Technical Field

[0001] This utility model relates to the field of veterinary drug processing equipment technology, specifically a granulation equipment for veterinary drug production and processing. Background Technology

[0002] Currently, in the specific production and processing of veterinary drugs, in order to meet different usage needs and facilitate packaging, powdered raw materials are subjected to secondary processing through existing extrusion granulation equipment, thereby transforming the powdered raw materials into granular raw materials. As an existing technology, the relevant technical content of extrusion granulation equipment has been disclosed, namely, "the main principle is to continuously accept powdered raw materials through a porous mold, and then use its own porous structure to circulate and extrude, ultimately converting the powdered raw materials into granular raw materials to meet processing requirements."

[0003] However, during actual processing, the applicant discovered that some of the extruded granular raw materials would lose a small amount of residue during the material transfer process. Although the amount was small, from the perspective of long-term processing prospects, if it could be effectively reprocessed or put back into production, it could reduce the cost of raw material usage. Therefore, in order to address the above problem, this application will provide a granulation equipment for veterinary drug production and processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a granulation equipment for veterinary drug production and processing, which solves the problems mentioned in the background.

A hopper and a spiral conveying assembly are provided on the top side of one side of the granulation mechanism body. The spiral conveying assembly can guide the raw materials inside the hopper into the working space inside the granulation mechanism body for extrusion into granulation in a spiral output manner. A discharge port is provided at the bottom of the granulation mechanism body. A transfer box is fitted outside the bottom port of the discharge port. A composite conveyor belt and two drive rollers are fitted inside the transfer box. The two drive rollers are respectively fitted inside the front and rear ends of the transfer box and then rub against the inner walls of the front and rear ends of the composite conveyor belt. One end of one of the drive rollers is connected to a servo motor installed on the surface of the transfer box.

[0006] The bottom surface of the transfer box is fixed with a bracket, and the bottom structure of the transfer box is set as a conical tube structure. The bottom port of the conical tube structure is externally threaded with a second internally threaded cover. The front inner side of the transfer box is fitted with a composite discharge pipe that can fit and connect with the front surface of the composite conveyor belt. The bottom of the composite discharge pipe penetrates the front structure of the transfer box and is fitted with a first internally threaded cover.

[0007] Preferably, the composite conveyor belt includes an output belt body, the top and bottom of which are provided with relief grooves, and a filter screen is fixedly nested in the relief grooves. The surfaces on both sides of the output belt body are respectively attached to the inner walls of the two sides of the transfer box.

[0008] Preferably, the bottom structure of the composite discharge pipe is configured as an inverted cone pipe structure, and the outer surface of the port at the bottom of the inverted cone pipe structure is provided with an external thread, and the first internal thread cap is threadedly connected to the outside of the port at the bottom of the inverted cone pipe structure.

[0009] Preferably, the composite conveyor belt is internally fitted with a baffle and a reset shaft. The reset shaft includes a positioning sleeve, a rotating shaft, and a torsion spring. The positioning sleeve is mounted on the outer side of one end of the rotating shaft via a bearing, and the two ends of the torsion spring are respectively fixedly connected to the surface of one end of the rotating shaft and the inner wall of the positioning sleeve. One end of the positioning sleeve is fixedly connected to the inner wall of the transfer box, and the other end of the positioning sleeve is fixedly connected to one side of the baffle.

[0010] Preferably, a meshing transmission assembly is provided between the positioning sleeve and the transmission roller closest to it, and the stop bar and the reset shaft can reciprocate to impact the inner wall of the composite conveyor belt under the rotation transmission of the meshing transmission assembly along with the transmission roller.

[0011] The meshing transmission assembly includes a half gear and a transmission gear. The half gear is fixedly connected to the end surface of the transmission roller and has a first clearance space between it and the inner wall of the composite conveyor belt. The transmission gear is fixedly sleeved on the surface of one end of the rotating shaft and has a second clearance space between it and the inner wall of the composite conveyor belt.

[0012] Preferably, an air conveying assembly is provided on the other end of the transmission roller inside the front end of the transfer box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a servo motor to drive a composite conveyor belt and transmission rollers. The granular raw materials flowing through the discharge port channel into the transfer box are automatically transported by the rotating composite conveyor belt to the interior of the composite discharge pipe. During the conveying process, some of the raw material residue that flows out of the granular raw materials will enter the bottom inner space of the transfer box through the filter screen inside the composite conveyor belt for centralized collection. This meets the needs of subsequent centralized collection and reprocessing, and reduces the cost of raw material use.

[0016] 2. This utility model consists of a set of baffles, a reset shaft, half gears, and a transmission gear to form a vibrating discharge device. After being used in sync with a single transmission roller, the transmission roller will drive the corresponding half gear to periodically mesh with the transmission gear, which in turn will drive the rotating shaft and the baffles to rotate synchronously. This causes the baffles to gently strike the composite conveyor belt, thereby increasing the vibration amplitude of the composite conveyor belt during the conveying process without interfering with the material conveying process, and accelerating the speed at which the raw material residue flows through the filter screen into the bottom space of the transfer box.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 A pelletizing device for veterinary drug production and processing includes a pelletizing mechanism body 1 and a support platform installed at the bottom of the pelletizing mechanism body 1. A hopper 2 and a screw conveying assembly 4 are provided on the top side of the pelletizing mechanism body 1. The screw conveying assembly 4 can introduce the raw materials inside the hopper 2 into the working space inside the pelletizing mechanism body 1 for extrusion into pellets in a screw output manner. A discharge port 3 is provided at the bottom of the pelletizing mechanism body 1. A transfer box 5 is fitted outside the bottom port of the discharge port 3. A composite conveyor belt 6 and two drive rollers 7 are fitted inside the transfer box 5. The two drive rollers 7 are respectively fitted inside the front and rear ends of the transfer box 5 and then rub against the inner walls of the front and rear ends of the composite conveyor belt 6. One end of one of the drive rollers 7 is connected to a servo motor 8 installed on the surface of the transfer box 5.

[0027] The composite conveyor belt 6 includes an output belt body, with clearance grooves at the top and bottom of the output belt body, and a filter screen is fixedly nested in the clearance grooves. The surfaces on both sides of the output belt body are respectively attached to the inner walls of the transfer box 5.

[0028] A bracket is fixed on the bottom surface of the transfer box 5, and the bottom structure of the transfer box 5 is set as a conical tube structure. The bottom port of the conical tube structure is externally threaded with a second internal thread cover 11. The front inner side of the transfer box 5 is fitted with a composite discharge pipe 9 that can be attached to the front surface of the composite conveyor belt 6. The bottom of the composite discharge pipe 9 penetrates the front structure of the transfer box 5 and is fitted with a first internal thread cover 10.

[0029] The bottom structure of the composite discharge pipe 9 is set as an inverted cone pipe structure, and the outer surface of the port at the bottom of the inverted cone pipe structure is provided with external threads. The first internal thread cover 10 is threadedly connected to the outside of the port at the bottom of the inverted cone pipe structure.

[0030] In practical use: the raw material in the hopper 2 is spirally conveyed by the spiral conveyor assembly 4 to the working space inside the granulation mechanism body 1. Then, the granulation mechanism body 1 is activated to extrude and granulate the raw material. The resulting granules are then conveyed through the discharge port 3 to the top inner side of the transfer box 5, and then fall onto the top surface of the rear end of the composite conveyor belt 6. Next, the servo motor 8 is started and the output end of the servo motor 8 drives the corresponding transmission roller 7. Then, supported by the transfer box 5 and another transmission roller 7, the composite conveyor belt 6 automatically guides the granules to the interior of the composite discharge pipe 9. During the guiding process, some of the raw material residue that falls out of the granules will enter the bottom inner space of the transfer box 5 through the filter screen inside the composite conveyor belt 6 for centralized collection.

[0031] During the material conveying process of the composite conveyor belt 6, the first internal thread cover 10 is turned open and the collection container is placed at the bottom of the composite discharge pipe 9 for synchronous collection. Subsequently, during the work interval, another collection container is placed below the bottom of the transfer box 5 and the second internal thread cover 11 is turned open. The raw material residue collected on the bottom inner side of the transfer box 5 will enter the other collection container through the guide of the bottom structure of the transfer box 5.

[0032] Please see Figure 3-6 The composite conveyor belt 6 is internally fitted with a baffle 15 and a reset shaft 14. The reset shaft 14 includes a positioning sleeve 141, a rotating shaft 142 and a torsion spring 143. The positioning sleeve 141 is mounted on the outside of one end of the rotating shaft 142 through a bearing, and the two ends of the torsion spring 143 are respectively fixedly connected to the surface of one end of the rotating shaft 142 and the inner wall of the positioning sleeve 141. One end of the positioning sleeve 141 is fixedly connected to the inner wall of the transfer box 5, and the other end of the positioning sleeve 141 is fixedly connected to one side of the baffle 15.

[0033] A meshing transmission assembly is provided between the positioning sleeve 141 and the transmission roller 7 closest to it. The stop bar 15 and the reset shaft 14 can reciprocate to impact the inner wall of the composite conveyor belt 6 under the rotation transmission of the meshing transmission assembly along with the transmission roller 7. The meshing transmission assembly includes a half gear 12 and a transmission gear 13. The half gear 12 is fixedly connected to the end surface of the transmission roller 7 and there is a first clearance space between it and the inner wall of the composite conveyor belt 6. The transmission gear 13 is fixedly sleeved on the surface of one end of the rotating shaft 142 and there is a second clearance space between it and the inner wall of the composite conveyor belt 6.

[0034] In practical use: Considering that some granular raw materials overlap during the conveying of the composite conveyor belt 6, and the raw material residue flowing down may be blocked, a meshing transmission assembly and a baffle 15 are set to synchronously vibrate the composite conveyor belt 6 for material discharge, as detailed below:

[0035] During the process of the two drive rollers 7 being driven by the servo motor 8 and rotating to drive the composite conveyor belt 6, one of the drive rollers 7 will drive the corresponding half gear 12 to periodically mesh with the drive gear 13, which in turn will drive the rotating shaft 142 and the baffle 15 to rotate synchronously, so that the baffle 15 will gently strike the composite conveyor belt 6, thereby increasing the vibration amplitude of the composite conveyor belt 6 during the conveying process without interfering with the material conveying of the composite conveyor belt 6, and accelerating the speed at which the raw material residue flows through the filter screen into the bottom space of the transfer box 5;

[0036] When the transmission gear 13 is not engaged with the half gear 12, the stop bar 15 and the rotating shaft 142 will be reset by the reset force of the torsion spring 143, and will be used again when impacted.

[0037] Please see Figure 7 An air conveying assembly 16 is provided on the other side of the transmission roller 7 located inside the front end of the transfer box 5. The air conveying assembly 16 includes a semi-open box 161, a fan blade 162, a first valve pipe 163, a second valve pipe 164, and a third valve pipe 165. The semi-open box 161 is installed on the surface of the transfer box 5 and covers the outer side of the other end of the corresponding transmission roller 7. The fan blade 162 is installed on the end surface of the other end of the corresponding transmission roller 7. One end of the first valve pipe 163, one end of the second valve pipe 164, and one end of the third valve pipe 165 are all fixedly sleeved inside the semi-open box 161, and the other end of the third valve pipe 165 is sleeved inside the transfer box 5.

[0038] In practical use: Considering that the raw material residue collected at the bottom of the transfer box 5 may have a large amount of residue due to gravity alone, after the initial collection operation is completed, the existing filter screen can be fitted and tied to the bottom port of the transfer box 5, and then the first internal thread cover 10 can be reset and locked.

[0039] Next, the internal valves of the first valve pipe 163 and the third valve pipe 165 are opened, the servo motor 8 is started, and the output end of the servo motor 8 drives the corresponding transmission roller 7. At the same time, the fan blades 162 associated with the transmission roller 7 will actively accelerate the air inside the semi-open box 161. The accelerated air will then enter the transfer box 5 through the third valve pipe 165 and finally be output from the bottom port of the transfer box 5. In this way, the airflow carries away the residual raw material residue inside the transfer box 5 for active outflow and cleaning, reducing the amount of residual raw material residue inside the transfer box 5.
