Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a dryer for drying vitamin tablets after they have been formed. Background Technology

[0002] Vitamins are essential nutrients for the human body. Normally, the body cannot synthesize vitamins (with vitamin D being an exception), or the amount synthesized is extremely small, so it must obtain them from food. Natural foods contain vitamins or their precursor compounds. Although the human body requires small amounts of vitamins, they are crucial; deficiency can lead to various vitamin deficiency diseases. To prevent vitamin deficiency diseases, people often take vitamin supplements.

[0003] In the production process of vitamin tablets, the drying process after molding is one of the key steps. Drying removes moisture adhering to the surface of the vitamin tablets, making them suitable for use and storage, and facilitating subsequent packaging, transportation, and sales. Currently, dryers are used in production for drying vitamin tablets after molding. However, because vitamin tablets are typically small in size, they tend to stack on top of each other in the drying chamber of the dryer, making it difficult to completely and effectively remove moisture during the drying process. Utility Model Content

[0004] The purpose of this invention is to provide a drying machine for drying vitamin tablets after they have been formed, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0016] 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.

[0017] Example 1:

[0018] This utility model provides a drying machine for drying vitamin tablets after molding, including a frame 1. The frame 1 is fixedly mounted with a feeding conveyor belt 2, a drying conveyor belt 3, and a drying device 4. A slide rail 5 and a motor 6 are fixedly mounted at the junction of the feeding conveyor belt 2 and the drying conveyor belt 3. A translation frame 7 is movably mounted on the slide rail 5. The motor 6 is driven by a lead screw 8 to connect to the translation frame 7. A cylinder 9 is fixedly mounted on the translation frame 7, and the cylinder 9 drives a lifting frame 10. A suction cup assembly 11 is fixedly mounted on the lifting frame 10. A flow divider plate 12 is fixedly mounted on the feeding conveyor belt 2, and the flow divider plate 12 has multiple flow divider grooves 13 and baffles 14. The drying device 4 includes a heat insulation shell 15 and an assembly frame 16, and a heating element 17 is fixedly mounted on the assembly frame 16. An exhaust vent 18 is provided at the top of the drying device 4, and a fan 19 is fixedly mounted at the exhaust vent 18. The thickness of the flow divider plate 12 is equal to the thickness of the vitamin tablets to be dried, and the baffles 14 are positioned above the flow divider grooves 13.

[0019] Through the above technical solution, this utility model uses the feeding conveyor belt 2 to transport undried vitamin tablets to the diversion plate 12. Under the action of the diversion trough 13 and the baffle 14, the vitamin tablets enter the diversion trough 13 individually. The suction cup assembly 11 is adjusted in position by the translation frame 7 moving in the X-axis direction and the lifting frame 10 moving in the Z-axis direction. During operation, the motor 6 drives the translation frame 7 to move to the diversion plate 12 through the lead screw 8. The cylinder 9 is activated, driving the lifting frame 10 to move down. The suction cup assembly 11 adsorbs and fixes the vitamin tablets to be dried in the diversion trough 13. The cylinder 9 then drives the lifting frame 10 to move up. At the same time, the motor 6 drives the translation frame 7 to move to the drying conveyor belt 3 and places the vitamin tablets to be dried on the drying conveyor belt 3. The drying conveyor belt 3 transports the vitamin tablets to the drying device 4 for drying. The robotic arm picks up and places the vitamin tablets to be dried, preventing the vitamin tablets from stacking together during the drying process, ensuring that the vitamin tablets are completely dehydrated, and improving the quality of the vitamin tablets.

[0020] Example 2:

[0021] In this embodiment, the frame 1 serves as the supporting structure for the entire equipment, and all functional components are fixedly mounted on it. The feeding conveyor belt 2 is used to transport undried vitamin tablets, and its end forms a docking structure with the drying conveyor belt 3. A translation mechanism consisting of a slide rail 5 and a motor 6 is provided at the docking point. A translation frame 7 that can move horizontally is movably mounted on the slide rail 5. The motor 6 is connected to the translation frame 7 through a lead screw 8 transmission mechanism to achieve precise position control of the translation frame 7.

[0022] A cylinder 9 is fixedly installed on the translation frame 7. This cylinder 9 serves as a vertical drive mechanism, and its piston rod is connected to the lifting frame 10. Driven by the cylinder 9, the lifting frame 10 can move vertically up and down. A suction cup assembly 11 for absorbing vitamin tablets is fixedly installed at the bottom of the lifting frame 10. The suction cup assembly 11 consists of multiple vacuum suction cups 11, capable of simultaneously absorbing multiple vitamin tablets. A specially designed diverting plate 12 is provided on the feeding conveyor belt 2. Multiple parallel diverting grooves 13 are formed on the diverting plate 12, and a baffle 14 structure is provided at the inlet of each diverting groove 13. The width of the diverting groove 13 is slightly larger than the diameter of the vitamin tablet, ensuring that the vitamin tablet can enter the diverting groove 13 individually.

[0023] During operation, undried vitamin tablets are conveyed to the distribution plate 12 via the feeding conveyor belt 2. Under the action of the distribution groove 13 and baffle 14 on the distribution plate 12, the vitamin tablets are separated one by one and positioned within the distribution groove 13. At this time, the motor 6 drives the translation frame 7 to move along the slide rail 5 above the distribution plate 12, and the cylinder 9 activates to lower the lifting frame 10, causing the suction cup assembly 11 to contact and adhere the vitamin tablets in the distribution groove 13. After adsorption is complete, the cylinder 9 drives the lifting frame 10 to rise, while the motor 6 drives the translation frame 7 to move above the drying conveyor belt 3. The suction cup assembly 11 releases the vitamin tablets, precisely placing them on the drying conveyor belt 3. The drying conveyor belt 3 then transports the vitamin tablets to the drying device 4 for drying.

[0024] The key to this embodiment lies in the precise transfer of vitamin tablets via a robotic arm-like pick-and-place mechanism. The coordinated movement of the translation frame 7 and the lifting frame 10 enables the suction cup assembly 11 to be precisely positioned in both the X and Z axes. The diversion channel 13 structure of the diversion plate 12 ensures that the vitamin tablets are individually separated before transfer. This design effectively avoids the problem of vitamin tablets stacking together during traditional drying processes, ensuring that each vitamin tablet is fully exposed to the drying environment, guaranteeing uniform and thorough moisture removal. The entire transfer process is highly automated, precise, and reliable, significantly improving the drying quality and production efficiency of the vitamin tablets.

[0025] Example 3:

[0026] The drying device 4 in this embodiment includes a heat insulation shell 15 and an assembly frame 16, on which the heating element 17 is fixedly mounted. The heat insulation shell 15 adopts a double-layer hollow structure, with the inner layer being a high-temperature resistant stainless steel plate and the outer layer being a galvanized steel plate, with ceramic fiber insulation material filling the space between the two layers. This structural design effectively blocks the heat generated by the heating element 17 from radiating outward, reducing the temperature rise in the workshop and improving the working environment. The top of the heat insulation shell 15 is equipped with an openable maintenance door for easy maintenance and replacement of the internal heating element 17.

[0027] The assembly frame 16 is welded from high-temperature resistant alloy steel and is fixed inside the heat insulation shell 15 in a frame structure. Multiple heating elements 17 are evenly spaced and installed on the horizontal beams of the assembly frame 16. Each heating element 17 uses a quartz glass tube encapsulating a resistance wire; when energized, the resistance wire heats up and radiates heat outward through the quartz glass tube. The heating elements 17 are arranged in parallel to ensure that the vitamin tablets are heated evenly as the drying conveyor belt 3 passes through. A guide plate is provided at the bottom of the assembly frame 16 to guide the hot air generated by the heating elements 17 to the surface of the drying conveyor belt 3, improving heat energy utilization.

[0028] The drying conveyor belt 3 uses a metal mesh belt structure with mesh sizes smaller than the minimum size of vitamin tablets, ensuring that the tablets do not fall during transport. The metal mesh belt has good air permeability, allowing hot air to fully contact the surface of the vitamin tablets and accelerate moisture evaporation. The conveyor belt speed is adjustable, allowing for adjustments to the drying time according to the drying requirements of different vitamin tablets. A water collection tank is located below the conveyor belt to collect dripping water during the drying process, keeping the equipment interior clean.

[0029] Heating element 17 achieves precise temperature control through a temperature control system. A temperature sensor monitors the temperature of the drying zone in real time and feeds the signal back to the control system. The control system automatically adjusts the power of heating element 17 according to a preset drying temperature curve, ensuring that the vitamin tablets are dried under optimal temperature conditions. The temperature control accuracy can reach ±1℃, preventing excessively high temperatures from damaging the vitamin components or insufficient temperatures from affecting the drying effect.

[0030] The inlet and outlet ends of the heat insulation shell 15 are equipped with air curtain devices, which form an air barrier through high-speed airflow to reduce the loss of internal heat. The airflow direction of the air curtain is at a certain angle to the running direction of the drying conveyor belt 3, which can effectively block heat leakage without interfering with the normal transportation of vitamin tablets. The wind speed of the air curtain device is adjustable and can be optimized according to actual production needs.

[0031] The drying unit 4 is also equipped with a humidity monitoring system, which monitors the air humidity in real time through humidity sensors installed in the drying area. When the humidity reaches a set threshold, the system automatically starts the dehumidification fan to expel the humid air from the equipment and maintain optimal humidity conditions for drying. The exhaust volume of the dehumidification fan can be automatically adjusted according to humidity changes, achieving intelligent control.

[0032] Example 4:

[0033] In this embodiment, the drying device 4 has an exhaust vent 18 on its top, and a fan 19 is fixedly installed at the exhaust vent 18. The exhaust vent 18 is located at the top center of the heat insulation shell 15 of the drying device 4, and is arranged perpendicular to the running direction of the drying conveyor belt 3. The exhaust vent 18 has a rectangular structure, and its length direction matches the width of the drying conveyor belt 3, ensuring that it can cover the entire width range of the drying area. The fan 19 has an axial flow structure and is fixedly installed above the exhaust vent 18 by bolts. The motor 6 of the fan 19 is external and equipped with a waterproof and dustproof cover.

[0034] During the drying process, the heat generated by the heating element 17 heats and dries the vitamin tablets on the drying conveyor belt 3 through thermal convection and thermal radiation. As the temperature rises, the moisture on the surface of the vitamin tablets gradually evaporates to form water vapor, and at the same time, the volatile components in the vitamin raw materials also produce a certain odor. This water vapor and odor rise naturally under the action of hot air convection and accumulate in the upper space of the drying device 4.

[0035] When fan 19 operates, it generates negative pressure suction, rapidly expelling water vapor and odors accumulated on the upper part of drying device 4 through exhaust port 18. The rectangular structure design of exhaust port 18 ensures uniform airflow throughout the drying area, preventing steam stagnation in localized areas. The speed of fan 19 can be adjusted according to drying process requirements to adapt to exhaust needs under different humidity conditions.

[0036] The exhaust system and the heat insulation shell 15 of the drying device 4 form a closed airflow circulation path. Fresh air is naturally replenished from the feed end of the drying conveyor belt 3, forming an upward airflow. This airflow organization method can ensure the drying effect while also removing moisture and odors in a timely manner. The continuous operation of the fan 19 ensures that the inside of the drying device 4 is always kept in a slightly negative pressure state, preventing moisture from accumulating inside the device.

[0037] Example 5:

[0038] In this embodiment, a feeding conveyor belt 2, a drying conveyor belt 3, and a drying device 4 are fixedly installed on the frame 1. A slide rail 5 and a motor 6 are provided at the junction of the feeding conveyor belt 2 and the drying conveyor belt 3. A translation frame 7 is movably installed on the slide rail 5. The motor 6 is connected to the translation frame 7 via a lead screw 8, allowing the translation frame 7 to move horizontally along the slide rail 5. A cylinder 9 is fixedly installed on the translation frame 7, driving a lifting frame 10, which can move vertically up and down. A suction cup assembly 11 is fixedly installed on the lifting frame 10 for adsorbing the vitamin tablets to be dried.

[0039] A diversion plate 12 is fixedly installed on the feeding conveyor belt 2. The diversion plate 12 has multiple diversion grooves 13. The width of the diversion grooves 13 matches the size of the vitamin tablets to be dried, ensuring that the vitamin tablets can smoothly enter the diversion grooves 13. The thickness of the diversion plate 12 is equal to the thickness of the vitamin tablets to be dried, so that the vitamin tablets are arranged in a single layer in the diversion grooves 13, avoiding stacking. A baffle 14 is provided above the diversion grooves 13. The function of the baffle 14 is to restrict the movement of the vitamin tablets in the diversion grooves 13, preventing them from jumping out of the diversion grooves 13 or stacking together due to vibration or inertia during the conveying process.

[0040] During the drying process, undried vitamin tablets are conveyed to the diversion plate 12 by the feeding conveyor belt 2. Because the width and thickness of the diversion trough 13 match the vitamin tablets, the tablets can enter the diversion trough 13 one by one and maintain a single-layer arrangement under the constraint of the baffle 14. Subsequently, the motor 6 drives the translation frame 7 to move along the slide rail 5 to the position of the diversion plate 12. The cylinder 9 is activated, driving the lifting frame 10 to descend, so that the suction cup assembly 11 contacts and adsorbs the vitamin tablets in the diversion trough 13. After adsorption is complete, the cylinder 9 drives the lifting frame 10 to rise, while the motor 6 drives the translation frame 7 to move above the drying conveyor belt 3. The suction cup assembly 11 releases the vitamin tablets, allowing them to fall smoothly onto the drying conveyor belt 3, which then transports them to the drying device 4 for drying.

[0041] With the above structure, this embodiment ensures that the vitamin tablets remain in a single layer during the drying process, avoiding stacking, thereby improving drying efficiency, ensuring that the moisture in the vitamin tablets is completely removed, and improving product quality.
