Description

Material feeding device

Technical Field

The utility model relates to a material feeding device.

Background

In the production process, the phenomenon of material blockage and blockage can be caused, so that the production cannot be continuously carried out, and the frequency is 2~3 times a day. When the material dryer discharges materials, the air cylinder moves to retreat at a constant speed, the discharging valve is opened at a constant speed until all valve openings are opened, the reclaimed materials are instantly sprayed out from the outlet, and the reclaimed materials are not enough in negative pressure of the material suction port and are blocked instantly due to the fact that the appearance of the reclaimed materials looks irregular and the sizes of the reclaimed materials are different, so that the production cannot be operated normally and continuously. The fundamental reason is that the valve opening is too large (determined by the stroke of the cylinder), the valve is opened too fast (lacking a speed adjusting device), the negative pressure is insufficient, all irregular materials are accumulated at the valve opening in a large quantity in a short time, and the phenomenon of material blockage is formed.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, 2 and 3, the driving end of the driving cylinder 3 is connected to the valve core 6 inside the three-way valve 2, the three-way valve 2 further includes a first passage 21, a second passage 22 and a third passage 23, the valve core 6 corresponds to the switch of the three-way valve 2, the position of the valve core 6 is moved so that the first passage 21, the second passage 22 and the third passage 23 can communicate with each other, the first passage 21 is connected to the discharge port of the feeding bin 1, the material reaches the inside of the three-way valve 2 through the first passage 21, the second passage 22 is connected to the air supply device, so that the air flow enters the inside of the three-way valve 2 through the second passage 22 to blow the material to the third passage 23, the third passage 23 is connected to the vacuum suction device, the vacuum suction device has an adsorption effect on the material, so that the material reaches the next process through the third passage 23, the driving cylinder 3 is provided with a valve core 31 for limiting the air flow, when the air pressure inside the driving cylinder 3 reaches the exhaust threshold value of the valve core 31, the driving cylinder 3 is provided with a limited distance 32, and the driving rod 32 is limited distance of the driving cylinder 3.

The inlet of the second channel 22 is provided with a regulating valve 4 for regulating the air flow, when the air flow at the inlet of the second channel 22 is too large, the air flow is reduced through the regulating valve 4, so that excessive waste is avoided, and meanwhile, the balance of the internal flow of the three-way valve 2 is ensured.

A muffler for muffling noise is provided corresponding to the valve core 31, and high pressure in the drive cylinder 3 is removed by the valve core 31, so that noise is generated, and the noise can be removed by the muffler.

The aperture of the third channel 23 is larger than that of the first channel 21, in this example, the third channel 23 is used for sucking the materials to the next processing step, so that the third channel is larger than the blanking aperture of the first channel 21, more materials can be adsorbed, the adsorption is faster, and the efficiency is high.

The driving cylinder 3 is provided with a position sensor 5, the position sensor 5 is arranged at a position corresponding to the limit sleeve rod 32, the position sensor 5 is matched with the limit sleeve rod 32, and after a set distance is reached, the position sensor 5 sends an instruction to the driving cylinder 3.

In this example, the limit sleeve rod 32 is sleeved on the driving end of the driving cylinder 3, and can be installed at other positions in practical use as long as the limit sleeve rod can work in cooperation with the position sensor 5.

The limiting sleeve rod 32 is provided with a compression spring or other structures with buffering effects, and the compression spring plays a role in buffering due to the effect of inertia, so that the phenomenon that the limiting sleeve rod 32 collides with the driving cylinder 3 to cause equipment damage is avoided.

The working principle is as follows:

when the speed of the driving end of the driving cylinder 3 reaches the set maximum value, that is, the air pressure in the driving cylinder 3 reaches the exhaust threshold of the valve core 31, the valve core 31 starts to discharge partial air flow, the speed of the driving end of the driving cylinder 3 is reduced through the reduction of the air pressure, the blanking is fast because of the fast speed, and the blockage is easily caused, when the driving cylinder 3 reaches the set distance, the distance is limited by the limit sleeve rod 32 on the driving cylinder 3, the position sensor 5 sends an instruction to the driving cylinder 3 to stop moving, but the driving cylinder 3 supplies air and supplies air, when the air pressure in the driving cylinder 2 reaches the exhaust threshold of the valve core 31, the valve core 31 discharges a small amount of air flow again, so that the air pressure in the driving cylinder 3 is proper, at the moment, the position of the feed hole in the three-way valve 2 can be kept proper, the existing position of the feed hole can be kept unchanged, meanwhile, the air flow of the air supply end can be adjusted by the adjusting valve 4, so that the pressure value of the air supply end and the air suction end of the three-way valve 2 reach a certain pressure balance, the valve core 6 can be opened uniformly and displaced for a certain time, the blockage can be controlled according to the set valve core 31, the speed and displacement of the irregular-shaped material can be controlled, and the irregular material can not blocked.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
