Description

Technical Field

[0001] This utility model relates to the field of tobacco additive production technology, specifically to a spiral sorting device based on an automatic feeding device. Background Technology

[0002] Additives are often added during cigarette production. For example, spherical particles with a size of 1.4mm ± 0.15mm and a weight of 0.002 ± 0.0008g / particle are added to the filter tip. Since the size of the produced spherical particles varies, and some are outside the specified range, it is usually necessary to sort the spherical particles of different sizes to obtain spherical particles within the expected size range as additives. Currently, the most common particle sorting equipment is the spiral sorting mechanism. The feeding of the spiral sorting mechanism is usually the feeding hopper at its inlet end. Due to the limited capacity of the feeding hopper, manual feeding is required, which is done approximately every 20 minutes. Because it is industrial production, the labor intensity is very high, and the feeding efficiency is very low, only about 2.5kg / hour. In addition, the feeding hopper is located at a high position, and workers have to use steps to feed the particles. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a spiral sorting device based on an automatic feeding device to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A spiral sorting device based on an automatic feeding device includes: a spiral sorting mechanism and a storage bin. The spiral sorting mechanism has a discharge bin at the feeding end. The granular material in the storage bin is sucked into the feeding channel by a pneumatic suction device and then sent into the discharge bin through the feeding channel.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, the spiral sorting mechanism is fixed on the frame, and the storage bin is fixed on the frame via a bracket.

[0007] Furthermore, the pneumatic suction device includes: a pressure reducing valve and a three-way connector. The air inlet of the pressure reducing valve is connected to an air source. One of the three interfaces of the three-way connector is connected to the discharge port at the bottom of the storage bin via a suction pipe, one interface is connected to the air outlet of the pressure reducing valve via an air supply pipe, and one interface is connected to the feed end of the feeding channel.

[0008] Furthermore, the outlet of the pressure reducing valve is connected to one interface of the tee connector via a ball valve.

[0009] Furthermore, the tee connector is fixed to the side wall of the storage silo, and the pressure reducing valve is fixed to the side of the bracket.

[0010] Furthermore, the bottom of the frame is equipped with multiple omnidirectional brake wheels.

[0011] Furthermore, the spiral sorting mechanism includes: a column and a spiral sorting trough fixed to the column in a circumferential manner, with the discharge bin located above the spiral sorting trough and fixed to the column.

[0012] Furthermore, the bottom plate of the feeding hopper is inclined downwards, and the discharge port of the feeding hopper is located at the lower end of the bottom plate.

[0013] Furthermore, the inclination angle of the base plate is 15°.

[0014] Furthermore, the air pressure in the feeding channel is 0.15MPa to 0.2MPa.

[0015] The beneficial effects of this utility model are: Based on the original spiral sorting mechanism and feeding hopper, a storage hopper, a pneumatic suction device, and a feeding channel are added to automatically feed the feeding hopper, ensuring continuous feeding of the spiral sorting mechanism. When feeding, workers only need to put the spherical particles into the storage hopper, instead of using steps to feed to the feeding hopper located at a higher position, which would prevent workers from falling off the steps, thus improving safety and solving the problem of high intensity of manual feeding. The feeding efficiency has been increased from the original 2.5 kg / hour to 8 kg / hour, effectively meeting the actual needs of industrial production. Moreover, the use of compressed gas feeding can avoid impact on the particle surface, which would cause the formation of fragments, and the brittleness is ≤1.0%. Attached Figure Description

Detailed Implementation

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1 like Figure 1, Figure 2 As shown, a spiral sorting device based on an automatic feeding device includes: a spiral sorting mechanism 1 and a storage bin 2. The spiral sorting mechanism 1 is provided with a discharge bin 3 at the feeding end. The granular material in the storage bin 2 is sucked into the feeding channel 5 by a pneumatic suction device 4 and then sent into the discharge bin 3 through the feeding channel 5 under the action of compressed gas. Then, it falls into the spiral sorting mechanism 1 through the discharge port of the discharge bin 3, and the spiral sorting mechanism 1 completes the sorting. The volume of the storage bin 2 is larger than the volume of the discharge bin 3.

[0020] Example 2 like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: The spiral sorting mechanism 1 is fixed on the frame 6, and the storage bin 2 is fixed on the frame 6 by the bracket 7, so as to facilitate the overall movement of the spiral sorting mechanism 1 and the storage bin 2.

[0021] Example 3 like Figure 1 As shown, this embodiment is a further improvement on embodiment 2, as detailed below: The pneumatic suction device 4 includes a pressure reducing valve 410 and a three-way connector 420. The air inlet of the pressure reducing valve 410 is connected to an air source, and one of the three interfaces of the three-way connector 420 is connected to the discharge port at the bottom of the storage bin 2 via a suction pipe 430, another interface is connected to the air outlet of the pressure reducing valve 410 via an air supply pipe 440, and the last interface is connected to the feed end of the feeding channel 5. Typically, the interface connected to the suction pipe 430 and the interface connected to the feeding channel 5 are coaxial. The working process is as follows: compressed gas is introduced from the air source into the pressure reducing valve 410, and the compressed gas... Gas enters the tee connector 420 through the gas supply pipe 440, and then enters the feeding channel 5 through the tee connector 420, thereby creating a negative pressure in the suction pipe 430 to draw the granular material in the storage bin 2 into the suction pipe 430. Then, it enters the feeding channel 5 through the tee connector 420 and is sent into the discharge bin 3 along with the compressed gas. The gas source is turned on and off intermittently, that is, the gas supply is turned on for a period of time to complete the feeding of the discharge bin 3, and then the gas supply is turned off for a period of time to stop the feeding of the discharge bin 3. This cycle is repeated. The gas source can be an air pump.

[0022] Example 4 like Figure 1 As shown, this embodiment is a further improvement on embodiment 3, as detailed below: The outlet of the pressure reducing valve 410 is connected to one interface of the three-way connector 420 via the ball valve 450. The ball valve 450 can be opened and closed to allow compressed gas to enter the three-way connector 420 through the pressure reducing valve 410.

[0023] Furthermore, the tee connector 420 is fixed to the side wall of the storage silo 2, and the pressure reducing valve 410 is fixed to the side of the bracket 7.

[0024] Example 5 like Figure 1 As shown, this embodiment is a further improvement on embodiment 2, 3, or 4, as detailed below: The bottom of the frame 6 is equipped with multiple universal brake wheels 8, which facilitates the overall movement of the equipment. After the equipment is moved into place, the universal brake wheels 8 themselves brake to lock it in place, preventing the equipment from moving randomly.

[0025] Example 6 like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 5, as detailed below: The spiral sorting mechanism 1 includes a column 110 and a spiral sorting trough 120 fixed around the column 110. The feeding bin 3 is located above the spiral sorting trough 120 and fixed to the column 110. The spiral sorting trough 120 sorts materials according to the existing technology. It utilizes the kinematic laws to effectively screen the good and bad products of spherical granular materials under the action of centrifugal force and gravity.

[0026] Example 7 like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 6, as detailed below: The bottom plate of the feeding bin 3 is inclined downwards, and the discharge port of the feeding bin 3 is located at the lower end of the bottom plate. The granular material in the feeding bin 3 can roll down to the discharge port of the feeding bin 3 by its own weight, so there is no need to equip it with a pushing mechanism.

[0027] Furthermore, the preferred tilt angle of the base plate is 15°.

[0028] Example 8 like Figure 1 As shown, this embodiment is a further improvement on any one of embodiments 1 to 7, as detailed below: The air pressure in the feeding channel 5 is 0.15MPa~0.2MPa. This pressure range can transport spherical particles of 1.2mm~1.6mm, that is, cover the target spherical particle size of 1.4mm±0.15mm to meet the usage requirements. If the pressure is too high, it will easily impact the surface of the particles and cause them to break.

[0029] Taking a particle mass of 0.002g / particle and a particle size of 1.4mm as an example, the discharge port of the feeding hopper 3 is 170cm above the ground, and the discharge port of the spiral sorting trough 120 is 50cm above the ground. Based on this: 1) Particle velocity at the discharge port: According to the law of conservation of energy: Initial potential energy = Exit kinetic energy

[0030] Right now .

[0031] 2) Momentum of a single particle: momentum

[0032] 3) Impulse per particle: Assuming the velocity decreases from V to 0, the change in momentum upon impact is:

[0033] That is, the maximum impulse does not exceed This means that it can meet the requirements for shot sorting of products with corresponding particle sizes.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
