Description

Technical Field

[0001] The utility model relates to the technical field of soft capsule production, in particular to a colloid mill for soft capsule production. Background Technique

[0002] When producing soft capsules, a colloid mill is needed to process raw materials. Specifically, except for the motor and some parts of the colloid mill product, all parts in contact with the material are made of high-strength stainless steel. At the same time, due to different grinding materials, the equipment also needs to have the characteristics of corrosion resistance to meet the needs of different uses. Therefore, the colloid mill is composed of stainless steel and semi-stainless steel colloid mills. Its basic principle is that through the high-speed relative movement between the fixed teeth and the moving teeth, the grinding head can rotate to grind the material. When grinding the material, due to the gap in the grinding head, the ground material will be stored between the grinding grooves of the grinding head. When the grinding grooves of the grinding head are filled with more material, the grinding head cannot effectively grind the material, resulting in insufficient grinding of the material. For this reason, we propose a colloid mill for soft capsule production. Content of the Utility Model

[0003] The utility model provides a colloid mill for soft capsule production, which solves the problems raised in the above background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A colloid mill for soft capsule production includes a bottom plate. A grinding fixed seat is installed on the bottom plate, and a feeding hopper is installed on the top of the grinding fixed seat. A rotating grinding head is installed inside the feeding hopper. The grinding head is in the shape of an inclined frustum of a cone. Uniformly arranged first grinding grooves, second grinding grooves, and third grinding grooves are arranged on the grinding head from top to bottom. The first grinding grooves, second grinding grooves, and third grinding grooves are inclined threaded sections, and the tooth diameters of the first grinding grooves, second grinding grooves, and third grinding grooves gradually become smaller. At the same time, multiple pairs of rotatable transmission gears are movably installed inside the lower grinding head, and eccentric wheels are fixedly connected to the transmission gears.

[0005] Optionally, the grinding head is movably installed on the bottom plate, and the center of the bottom end of the grinding head is fixedly connected to a first runner, and the first runner is movably sleeved inside the bottom plate.

[0006] Optionally, a second runner is connected to the inside of the bottom plate through a pin, and a transmission belt is jointly sleeved between the second runner and the first runner.

[0007] Optionally, a servo motor is fixedly installed on the bottom plate, and the output shaft of the servo motor extends into the inside of the bottom plate and is connected to the center of the second runner.

[0008] Optionally, a fixing column is fixedly connected to the bottom plate, and the fixing column passes through the center of the first runner and extends into the interior of the grinding head for movably sleeving with it.

[0009] Optionally, a second gear is fixedly connected to the outer side of the end of the fixing column extending into the interior of the grinding head, and the outer side of the second gear meshes with the transmission gear.

[0010] Optionally, the first grinding groove, the second grinding groove, and the third grinding groove are inclined in opposite directions to each other. The feeding hopper is threadedly sleeved on the grinding fixing seat, and a rotating rod is fixedly connected to the outer side of the feeding hopper. An outlet pipe communicating with the interior of the grinding fixing seat is fixedly installed on the grinding fixing seat.

[0011] The present utility model has the following beneficial effects:

[0012] 1. For the colloid mill for soft capsule production, driven by the output shaft of the servo motor and transmitted by the transmission belt, the grinding head can rotate to grind the material. Under the interaction of the first grinding groove, the second grinding groove, and the third grinding groove on the grinding head, the moving distance of the material can be effectively extended, thereby prolonging the grinding time of the material, and making the grinding of the material more sufficient.

[0013] 2. For the colloid mill for soft capsule production, driven by the rotation of the grinding head, the transmission gear can be driven to rotate. Under the action of the second gear, the transmission gear can drive the eccentric wheel to rotate while rotating itself. Under the action of the centrifugal force generated by the rotation of the eccentric wheel, the grinding head can generate vibration, enabling the material to move downward smoothly for grinding. And under the mutual action of the opposite eccentric wheels, the generated force can be relatively offset, increasing the vibration frequency without generating a large force on the grinding head.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 5 , a colloid mill for soft capsule production, including a bottom plate 1, a grinding fixed seat 2 is installed on the bottom plate 1, and a hopper 5 is installed on the top of the grinding fixed seat 2. Through the hopper 5, the material can be smoothly fed. A grinding head 7 for rotary grinding is installed inside the hopper 5. Under the rotation of the grinding head 7, the material can be ground. The grinding head 7 is in the shape of an inclined frustum, which can extend the grinding time of the material on the grinding head 7 and make the grinding more sufficient. The first grinding groove 8, the second grinding groove 9, and the third grinding groove 10 are arranged in a uniformly arranged manner from top to bottom on the grinding head 7. The first grinding groove 8, the second grinding groove 9, and the third grinding groove 10 are inclined thread segments, and the tooth diameters of the first grinding groove 8, the second grinding groove 9, and the third grinding groove 10 gradually decrease, so that the material can be gradually ground and made the grinding more delicate. At the same time, a plurality of pairs of rotatable transmission gears 15 are movably installed inside the lower grinding head 7, and an eccentric wheel 16 is fixedly connected to the transmission gear 15. The transmission gear 15 can drive the eccentric wheel 16 to rotate and rotate itself at the same time. Under the action of the centrifugal force generated by the rotation of the eccentric wheel 16, the grinding head 7 can generate vibration, so that the material can move downward smoothly and be ground. And under the mutual action of the relatively arranged eccentric wheels 16, the generated force can be relatively offset to increase the vibration frequency without generating a large force on the grinding head 7.

[0022] Please refer to Figures 1 to 4 , the grinding head 7 is movably installed on the bottom plate 1. The grinding head 7 can rotate at a fixed position on the bottom plate 1, and the center of the bottom end of the grinding head 7 is fixedly connected to a first runner 11. Driven by the first runner 11, the grinding head 7 can rotate. The first runner 11 is movably sleeved inside the bottom plate 1, and the first runner 11 can rotate at a fixed position on the bottom plate 1.

[0023] Please refer to Figures 1 to 4 , inside the bottom plate 1, a second runner 13 is connected by a shaft pin to form a hinge structure with the shaft pin as the rotation axis, enabling the second runner 13 to rotate at a fixed position on the bottom plate 1. A transmission belt 12 is sleeved jointly between the second runner 13 and the first runner 11. Through the transmission of the transmission belt 12, the second runner 13 can smoothly drive the first runner 11 to rotate.

[0024] Please refer to Figures 1 to 4 , a servo motor 6 is fixedly installed on the bottom plate 1. The output shaft of the servo motor 6 extends into the inside of the bottom plate 1 and is connected to the center of the second runner 13. Driven by the output shaft of the servo motor 6, the second runner 13 can rotate. The servo motor 6 is a prior art and will not be elaborated here.

[0025] Please refer to Figures 1 to 5 , a fixed column 14 is fixedly connected to the bottom plate 1. The fixed column 14 passes through the center of the first runner 11 and extends into the inside of the grinding head 7 and is movably sleeved therewith. The fixed column 14 can relatively limit the rotation position of the grinding head 7, making its rotation more stable.

[0026] Please refer to Figures 1 to 5 , on the outer side of one end of the fixed column 14 extending into the inside of the grinding head 7, a second gear 17 is fixedly connected. The outer side of the second gear 17 meshes with the transmission gear 15. Under the relative action of the second gear 17, the transmission gear 15 can rotate itself when the grinding head 7 drives the rotation.

[0027] Please refer to Figures 1 to 5 , the first grinding groove 8, the second grinding groove 9, and the third grinding groove 10 are inclined in opposite directions to each other, further extending the feeding trajectory of the material, making the grinding time of the material longer, and thus making the grinding more sufficient. The feeding hopper 5 is threadedly sleeved on the grinding fixing seat 2, and a rotating rod 4 is fixedly connected to the outer side of the feeding hopper 5. The feeding hopper 5 can be rotated through the rotating rod 4 to adjust the gap of the material grinding, thereby adjusting the relative fineness of the grinding. An outlet pipe 3 communicating with the inside of the grinding fixing seat 2 is fixedly installed on the grinding fixing seat 2, and then the ground material can be discharged smoothly.

[0028] In summary, when the colloid mill for soft capsule production is in use, the material is inverted into the feeding hopper 5. Then, driven by the output shaft of the servo motor 6, the second runner 13 can rotate, and through the transmission of the transmission belt 12, the first runner 11 can rotate. Driven by the first runner 11, the grinding head 7 can rotate. Under the rotation of the grinding head 7, the first grinding groove 8, the second grinding groove 9, and the third grinding groove 10 on it can grind the material. At the same time, under the action of the rotation of the grinding head 7, the transmission gear 15 can be driven to rotate. Under the action of the second gear 17, the transmission gear 15 can rotate and rotate around its own axis at the same time, and then the eccentric wheel 16 can rotate. Under the action of the centrifugal force generated by the rotation of the eccentric wheel 16, the grinding head 7 can vibrate, so that the material can move downward smoothly and be ground. And under the interaction of the relative eccentric wheels 16, the forces generated by them can be relatively offset, increasing the vibration frequency without exerting a large force on the grinding head 7.
