Description

Technical Field

[0001] This utility model relates to the field of capsule delivery technology, and in particular to a pneumatic delivery device for soft capsules. Background Technology

[0002] The production process of soft capsules typically includes steps such as forming, drying, and packaging. After being extruded and formed by forming equipment, soft capsules of the same batch are dried in a soft capsule dryer. During the drying process, some moisture is inevitably lost quickly, causing the capsule shell to become shriveled and shrink.

[0003] The existing soft capsules are sent out from the conveyor belt of the capsule production line equipment, and then collected manually in collection boxes before being transferred to the next process and transported centrally, or transported centrally using a conveyor belt. This method of transportation is not conducive to the counting, packaging and sorting of soft capsules, especially since most soft capsules are currently packaged in bottles. It requires manual secondary sorting to remove non-compliant soft capsules before filling, which is inefficient. On the other hand, the handling of soft capsules can cause them to be squeezed and deformed, which is labor-intensive, time-consuming and prone to quality problems. Utility Model Content

[0004] To address the technical problem of inconvenient sorting and conveying of soft capsules, this utility model provides a pneumatic conveying device for soft capsules.

[0005] The technical solution of this utility model is achieved through the following scheme: a pneumatic conveying device for soft capsules, including a support frame, a vibrating screening component, a pneumatic conveying system, and a discharge pipe. The support frame is provided with a feeding hopper, which is connected to the vibrating screening component. The support frame is equipped with the vibrating screening component and the pneumatic conveying system. The vibrating screening component is connected to a guide slope and a flow channel, respectively. The flow channel is connected to a waste bin. A discharge pipe is opened at the lowest point of the guide slope. The pneumatic conveying system is connected to the flow channel and the discharge pipe, respectively. A feeding roller is provided in the discharge pipe.

[0006] The above technical solution uses a vibration screening component to separate shriveled and shrunken soft capsules from normal soft capsules, reducing the number of defective products in subsequent processing and the time and labor required for manual sorting. The screened normal soft capsules slide down the guide slope to the discharge pipe, and the feeding speed and quantity of soft capsules are controlled by the feeding roller. The pneumatic conveying system pneumatically conveys the defective soft capsules and normal soft capsules separately, avoiding the accumulation of waste on the production site, maintaining the cleanliness of the production environment, and reducing the risk of damage to normal soft capsules during the conveying process.

[0007] Preferably, the vibration screening assembly includes a vibration motor, several spring columns, a feeding plate, and a screen. The feeding plate is laid in the through groove of the support frame, and the vibration motor and several spring columns are provided between the feeding plate and the support frame. The screen is provided on the feeding plate.

[0008] Preferably, the feeding plate abuts against the hopper channel, the screen is connected to the waste bin through the flow channel, the screen is in the shape of "n", and the feeding plate is in the shape of "7".

[0009] Through the above technical solutions, the combination of the vibrating motor and the spring column enables the feeding plate to generate effective vibration, which allows the soft capsules to be better dispersed, thereby accelerating the movement and screening process of the soft capsules on the screen and improving the accuracy and efficiency of screening. The "n"-shaped screen design increases the screening area, allowing more soft capsules to contact the screen at the same time. At the same time, the special shape of the screen also helps to guide unqualified soft capsules smoothly into the flow channel.

[0010] Preferably, the pneumatic conveying system includes a fan, a main air duct, several air outlets, and an auxiliary air duct. The fan is connected to the main air duct, the main air duct has several air outlets, the air outlets are connected to a flow channel, and the main air duct is connected to the auxiliary air duct.

[0011] Preferably, the flow channel is provided with a baffle plate, which obliquely blocks the air outlets above a number of them. The auxiliary air pipe is hung on the lower surface of the support frame by a number of hooks and is connected to the discharge pipe.

[0012] Through the above technical solutions, by setting baffles in the flow channel and obliquely blocking the air outlet to guide the airflow direction, unqualified soft capsules are more easily blown into the flow channel and guided to the waste bin under the action of airflow, while qualified soft capsules can smoothly slide down to the discharge pipe, and be discharged in conjunction with the discharge roller and auxiliary air pipe, realizing the separation and conveying of waste and qualified products; by fixing the auxiliary air pipe with hooks, the impact of vibration on the auxiliary air pipe is reduced, and it is easy to adjust according to the actual needs of the production site, thereby improving the overall layout efficiency of the production line.

[0013] Preferably, the discharge pipe includes a discharge inner cylinder, an air outlet outer cylinder, and a filter plate. The air outlet outer cylinder is sleeved on the discharge inner cylinder, the discharge roller is movably installed inside the discharge inner cylinder, the air outlet outer cylinder is connected to a pneumatic conveying system, and the end of the air outlet outer cylinder is connected to the end of the discharge inner cylinder through the filter plate.

[0014] Preferably, the guide slope is provided with a feeding plate.

[0015] Through the above technical solution, the outer air outlet cylinder is sleeved on the inner material discharge cylinder to form a double-layer structure. The outer air outlet cylinder is connected to the pneumatic conveying system, which allows the airflow to flow on the outside side of the inner material discharge cylinder, realizing gas-solid separation. The discharge roller, combined with the airflow support of the pneumatic conveying system, ensures the stability and continuity of the soft capsules during the material discharge process. The filter plate can effectively intercept the soft capsules that may be carried in the airflow and block the air outlet, maintaining the normal operation of the pneumatic conveying system.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses a vibrating screening component to screen soft capsules, separating shriveled and reduced soft capsules from normal soft capsules. This reduces the number of defective products in subsequent processing and the time and labor required for manual sorting. The screened normal soft capsules slide down the guide slope to the discharge pipe, and the feeding speed and quantity of soft capsules are controlled by the feeding roller. The pneumatic conveying system pneumatically conveys the defective soft capsules and normal soft capsules separately, avoiding the accumulation of waste on the production site, maintaining the cleanliness of the production environment, and reducing the risk of damage to normal soft capsules during the conveying process.

[0018] 2. The combination of the vibrating motor and the spring column enables the feeding plate to generate effective vibration, which helps to better disperse the soft capsules, thereby accelerating the movement and screening process of the soft capsules on the screen and improving the accuracy and efficiency of screening. The "n"-shaped screen design increases the screening area, allowing more soft capsules to contact the screen at the same time. At the same time, the special shape of the screen also helps to guide unqualified soft capsules smoothly into the flow channel.

[0019] 3. By installing baffles in the flow channel and obliquely blocking the air outlet, the airflow direction is guided, making it easier for unqualified soft capsules to be blown into the flow channel and guided to the waste bin under the action of airflow, while qualified soft capsules can smoothly slide down to the discharge pipe, and be discharged in conjunction with the discharge roller and auxiliary air pipe, realizing the separation and conveying of waste and qualified products; by fixing the auxiliary air pipe with hooks, the impact of vibration on the auxiliary air pipe is reduced, and it is easy to adjust according to the actual needs of the production site, thus improving the overall layout efficiency of the production line.

[0020] 4. The outer air outlet cylinder is fitted onto the inner material discharge cylinder, forming a double-layer structure. The outer air outlet cylinder is connected to the pneumatic conveying system, allowing the airflow to flow on the outside of the inner material discharge cylinder, achieving gas-solid separation. The discharge roller, combined with the airflow support of the pneumatic conveying system, ensures the stability and continuity of the soft capsules during the material discharge process. The filter plate can effectively intercept soft capsules that may be carried in the airflow and block the air outlet, maintaining the normal operation of the pneumatic conveying system.

[0027] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] A pneumatic delivery device for soft capsules, such as Figures 1-5 As shown, the device includes a support frame 1, a vibrating screening assembly 2, a pneumatic conveying system 3, and a discharge pipe 4. The support frame 1 is equipped with a feeding hopper with an inclined channel inside. The feeding hopper is connected to the vibrating screening assembly 2. The support frame 1 has an inclined channel adapted to the vibrating screening assembly 2. The entire device is inclined to the guide slope 6 and flows naturally under the action of gravity and vibration. The support frame 1 is equipped with the vibrating screening assembly 2 and the pneumatic conveying system 3. The vibrating screening assembly 2 is connected to the guide slope 6 and the flow channel 7. The flow channel 7 is connected to the waste bin 8. The lowest point of the guide slope 6 has a discharge pipe 4. The pneumatic conveying system 3 is connected to the flow channel 7 and the discharge pipe 4. The discharge pipe 4 is equipped with a feeding roller 5, which uses air to push the waste material and normal soft capsules out separately.

[0030] The vibrating screening assembly 2 includes a vibrating motor 21, several spring columns 22, a feeding plate 23, and a screen 24. The feeding plate 23 is laid in the through groove of the support frame 1. The vibrating motor 21 and several spring columns 22 are provided between the feeding plate 23 and the support frame 1. The screen 24 is provided on the feeding plate 23 as an elastic support element to buffer the vibration energy of the vibrating motor 21 and maintain the stability of the feeding plate 23. The screen 24 is evenly distributed between the feeding plate 23 and the support frame 1. The number of spring columns 22 is preferably six, located at the four corner edges and the two sides of the motor in the middle of the feeding plate 23. The vibrating motor 21 operates.

[0031] like Figure 2 As shown, the feeding plate 23 abuts against the hopper channel, and the screen 24 is connected to the waste bin 8 through the flow channel 7. The screen 24 is in an "n" shape and is built into the feeding plate 23. Two guide plates are provided on one side of the screen 24 near the flow channel 7, forming an "n" shape. A static safety distance is reserved between the guide plates and the flow channel 7, which can effectively prevent waste from entering the vibration zone where the vibration motor 21 is located. The feeding plate 23 is in a "7" shape and is laid obliquely in the channel of the support frame 1. The "7"-shaped end covers the surface of the channel and also reserves a static safety distance to prevent normal soft capsules from entering the vibration zone. The other end abuts against the channel of the hopper.

[0032] like Figure 1 As shown, the guide slope 6 is equipped with a guide plate. The number of guide plates is preferably two, which intersect to form a triangle. The discharge pipe 4 is located at the corner of the triangle, which is the lowest point of the guide slope 6. The normal soft capsules entering the guide slope 6 are guided to the discharge pipe 4 through the guide plate, and then discharged in batches by the subsequent discharge roller 5.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the pneumatic conveying system 3 includes a fan 31, a main air duct 32, several air outlets 33, and an auxiliary air duct 34. The fan 31 serves as the power source for the entire pneumatic conveying system 3, providing airflow to drive the material movement. The fan 31 is connected to the main air duct 32, which is located inside the support frame 1. Several air outlets 33 are located on the main air duct 32, and these outlets 33 are connected to the flow channel 7. The main air duct 32 is also connected to the auxiliary air duct 34. All the air outlets 33 are inclined downwards, and the flow channel 7 has an arc-shaped slope at the corner. This, combined with the baffle plate 9, guides the airflow, allowing it to enter the flow channel 7 at a certain angle, thus more effectively moving the defective soft capsules. At the same time, it prevents the airflow from directly impacting the bottom of the flow channel 7, ensuring the conveying of any dropped defective soft capsules. The baffle plate 9 also effectively guides and buffers the defective soft capsules. The fan 31 is installed on one side of the support frame 1.

[0034] The flow channel 7 is equipped with a baffle plate 9, which obliquely blocks several air outlets 33. The auxiliary air pipe 34 is hung on the lower surface of the support frame 1 by several hooks 10, which not only ensures the stability of the auxiliary air pipe 34, making it firmly installed and not easy to shake, thus ensuring the stable operation of the pneumatic conveying system 3, but also facilitates installation and maintenance. The auxiliary air pipe 34 is connected to the discharge pipe 4, providing auxiliary airflow to the discharge pipe 4 to help qualified materials be discharged smoothly from the equipment.

[0035] like Figure 5 As shown, the discharge pipe 4 includes a feeding inner cylinder 41, an air outlet outer cylinder 42, and a filter plate 43. The air outlet outer cylinder 42 is sleeved on the feeding inner cylinder 41. The feeding roller 5 is movably installed inside the feeding inner cylinder 41. The air outlet outer cylinder 42 is connected to the pneumatic conveying system 3. The end of the air outlet outer cylinder 42 is connected to the end of the feeding inner cylinder 41 through the filter plate 43. The auxiliary air pipe 34 is directly connected to the air outlet outer cylinder 42. The air outlet outer cylinder 42 is half-set, and the other side is sealed, so that the airflow is concentrated in the discharge direction, avoiding the soft capsules being blown back and reversed under the fully open setting, ensuring that the air outlet is directed towards the discharge port, and ensuring the single conveying direction. The end of the feeding inner cylinder 41 connected to the air outlet outer cylinder 42 is arc-shaped, so that the soft capsules can slide better and slide to the filter plate 43. The filter plate 43 realizes gas-solid separation (allowing airflow to pass through and intercepting soft capsules), and also prevents capsules from accidentally entering the pneumatic system through physical isolation. The air outlet of the filter plate 43 pneumatically conveys the soft capsules.

[0036] The feeding roller 5 can actively move the capsules to feed them in batches to prevent accumulation and blockage. The feeding roller 5 is a spiral roller, and a support plate is provided on the feeding plate on its guide slope. A drive motor is provided on the support plate. The drive motor drives the feeding roller 5 to rotate spirally in the feeding inner cylinder 41. The drive motor is covered with a protective shell to prevent the soft capsules from colliding with the drive motor. The size of the spiral roller is adapted to the feeding inner cylinder 41 so that the soft capsules will not enter the gap between the feeding contents and the spiral roller.

[0037] Working principle: The staff introduces the dried soft capsules into the feeding hopper. The PLC controller 101 then controls the start of the vibration screening component 2 to vibrate and screen the soft capsules. At this time, the unqualified capsules enter the flow channel 7 from the screen 24 of the vibration screening component 2, and are then conveyed into the waste bin 8 by the subsequent pneumatic conveying system 3.

[0038] Qualified capsules slide into the guide slope 6 and are fed in batches into the inner feed cylinder 41 by the feed roller 5 at the lowest point of the guide slope 6. Air is supplied into the outer air cylinder 42 through the auxiliary air pipe 34 and flows out from the bottom air outlet 33 of the outer air cylinder 42 to transport qualified capsules.

[0039] Vibration screening component 2, pneumatic conveying system 3 and feeding roller 5 are all externally connected to PLC controller 101. The parts and equipment are all conventional models in the prior art. In addition, the circuit connection and communication connection adopt conventional connection methods in the prior art, as described in this specification. The PLC controller 101 and the circuit and communication connection of each component are not detailed here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
