Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic conveying, in particular to a pneumatic conveying device for soft capsules. Background Art

[0002] The production process of soft capsules usually includes steps such as molding, drying and packaging. The soft capsules formed by extrusion equipment will be dried in a soft capsule dryer (drying cage). The existing soft capsule conveying method usually uses a material box or a material frame to receive the dried soft capsules and transport them in a centralized manner, or uses a conveyor belt for centralized transportation. This conveying method is not conducive to the counting and packaging of soft capsules, especially for the existing soft capsules that are mostly bottled, which require manual secondary sorting and filling, and the efficiency is relatively low. Utility Model Content

On the basis of this structure, the soft capsules can fall into the feeding pipe one by one through the feed conveying pipe, and under the action of the wind force provided by the blower, they are transported to the end of the feeding pipe away from the blower, ensuring that the subsequent counting and packaging work can be carried out more effectively.

[0007] In the pneumatic conveying device for soft capsules as described above, the inner diameter of the leakage tube is 1.2-1.4 times the diameter of the short axis of the soft capsules to be conveyed, which ensures that the soft capsules can maintain a vertical state and fall smoothly one by one, while effectively reducing the phenomenon of soft capsules being stuck in the leakage tube due to excessive squeezing.

[0008] As a preferred embodiment, in order to further prevent the soft capsules from getting stuck in the leakage tube and ensure the smooth falling of the soft capsules, the storage mechanism also includes a vibration motor capable of driving the storage hopper.

[0009] As a further preferred embodiment, in order to facilitate manual intervention when material jam occurs in the leakage pipe, the storage mechanism also includes two lifting motors arranged relatively to each other, and the transmission ends of the two lifting motors face upward, and the two sides of the storage hopper are respectively hingedly connected to the transmission ends of the two lifting motors, so that the storage hopper can be driven to rise and fall by the lifting motor, thereby making it easier for people to complete the post-blocking processing work from the lower end of the leakage pipe, and the two sides of the storage hopper are hingedly connected to the transmission ends of the two lifting motors, so that the shaking of the storage hopper under the action of the vibration motor is concentrated on the lower part, thereby preventing the soft capsules from shaking out from the upper end of the storage hopper.

[0010] The pneumatic conveying device for soft capsules as described above is a preferred embodiment. In order to prevent the setting of the air blower from affecting the material dropping of the storage mechanism and ensure the transportation of the soft capsules along the conveying pipe under the action of the air blower, a sealing cover is hingedly connected to the upper side of the storage hopper.

The structure of the conveying device (the above-mentioned soft capsule pneumatic conveying device) is described in detail below in conjunction with the accompanying drawings.

[0025] In this embodiment, combined with Figure 2First, let's talk about the structure of the storage mechanism 2. It includes a storage part 21, and the storage part 21 includes a funnel-shaped storage hopper 211. The lower side of the storage hopper 211 is also provided with a leakage pipe 212. The inner diameter of the leakage pipe 212 is set to be smaller than the long axis diameter of the soft capsule to be transported, and larger than the short axis diameter of the soft capsule to be transported, so that the oval soft capsules can fall vertically along the leakage pipe 212 one by one to the feeding mechanism 3.

[0026] As a preferred embodiment, the inner diameter of the leakage tube 212 is set to 1.2-1.4 times the diameter of the short axis of the soft capsule to be transported. Under this inner diameter, while ensuring that the soft capsules can maintain a vertical state and fall smoothly one by one, the phenomenon of soft capsules getting stuck in the leakage tube 212 due to excessive squeezing is effectively reduced.

[0027] As a further preference, in order to further prevent the soft capsules from getting stuck in the leakage tube 212 and ensure the smooth falling of the soft capsules, the storage mechanism 2 also includes a vibration motor 23 capable of driving the storage hopper 211. In order to ensure the vibration effect of the vibration motor 23, two vibration motors 23 are arranged opposite to each other on both sides of the storage hopper 211.

[0028] On the basis of the above structure, in order to facilitate manual intervention when material jam occurs in the leakage pipe 212, the storage mechanism 2 also includes two lifting motors 25 arranged relatively to each other, and the transmission ends of the two lifting motors 25 face upward, and the two sides of the storage hopper 211 are respectively hingedly connected to the transmission ends of the two lifting motors 25; the storage mechanism 2 also includes a vibration seat 24 with an opening in the middle, and the two vibration motors 23 are transmission-connected to the two sides of the vibration seat 24, and the lower part of the storage hopper 211 is inserted in the vibration seat 24, and the lifting motor 25 can drive the lifting of the storage hopper 211, so that people can more easily complete the processing work after the material jam from the lower end of the leakage pipe 212, and the two sides of the storage hopper 211 are hingedly connected to the transmission ends of the two lifting motors 25, so that the shaking of the storage hopper 211 under the action of the vibration motor 23 is concentrated at the lower part, preventing the soft capsule from shaking out from the upper end of the storage hopper 211.

[0029] In this embodiment, combined with Figure 3 As for the structure of the feeding mechanism 3, it includes a feeding pipe 311 arranged horizontally, one end of the feeding pipe 311 is connected to a blower 32, a feeding pipe 312 is arranged vertically on the upper middle part, and the lower end of the leakage pipe 212 is placed inside the upper end of the feeding pipe 312. Figure 4 , the soft capsules can fall into the feeding pipe 311 through the feeding pipe 312 one by one, and are transported to the end of the feeding pipe 311 away from the blower 32 under the action of the wind provided by the blower 32, so as to ensure that the subsequent counting and packaging work can be carried out more effectively.

[0030] Furthermore, in order to prevent the setting of the air feeder from affecting the material dropping of the storage mechanism 2 and ensure that the soft capsules can be smoothly transported along the delivery pipe 311 under the action of the air feeder 32, a sealing cover 22 is also hingedly connected to the upper side of the storage hopper 211.

[0031] As a preferred embodiment, in order to further ensure that the soft capsules in the delivery tube 311 can be smoothly driven to move under the action of wind and to ensure smooth delivery of the soft capsules when the delivery tube 311 is long, the inner cavity cross-section of the delivery tube 311 is a square structure, and the side length is smaller than the major axis diameter of the soft capsules to be delivered and not smaller than the minor axis diameter of the soft capsules to be delivered.

[0032] As a further preferred embodiment, in order to facilitate the counting work, a counter 33 is further provided at one end of the feed pipe 312 away from the blower 32 .

[0033] More preferably, in order to facilitate the filling work, a collecting funnel 4 is also provided on the outer side of one end of the feeding pipe 311 where the counter 33 is provided.

[0034] In the present embodiment, in order to prevent the soft capsules from getting stuck in the feed tube 312, the material of the feed tube 312 is preferably made of hard rubber so that it can vibrate along with the storage hopper 211. Specifically, the structure of the feed tube 312 includes a material receiving pipe section 3121, a receiving pipe section 3122 and a position adjustment pipe section 3123 which are sequentially arranged from top to bottom.

[0035] Specifically, the upper end of the material receiving pipe section 3121 is a cylindrical structure or a circular cross-section, and the lower end cross-section is a square. In order to ensure the smooth shaking of the leakage pipe 212 driven by the vibration motor 23, and at the same time ensure the sealing effect between the leakage pipe 212 and the smooth material pipe 312, the inner diameter of the upper end of the smooth material pipe 312 is larger than the outer diameter of the leakage pipe 212, and a silicone tube (not shown) is also provided between the smooth material pipe 312 and the leakage pipe 212.
