Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeders, in particular to a vacuum feeder which can avoid material blockage. Background Art
[0002] A vacuum loader is a device used for material handling. Its working principle is to use the air pressure difference to form an airflow to suck the material into the equipment, and then put the material into the designated location through the discharge port. Vacuum loader is widely used in packaging, food, medicine and other fields.
[0003] When transporting granular materials, the blockage problem has always been the main problem that plagues vacuum loaders. The common way to avoid blockage is to add a vibration device at the discharge port and feed port of the vacuum loaders, and to add a stirring device inside the vacuum loaders. The blockage problem of feeding is mainly caused by the blockage of the suction port of the vacuum generator in the vacuum loaders as the materials enter the loaders, resulting in reduced suction; the blockage problem of discharging is mainly caused by too much material accumulating at the discharge port after the feeding is completed. The effect of adding a vibration device is limited by the amplitude of the vibration, and the anti-blocking effect is not as good as adding a stirring device. Although the stirring device has a good anti-blocking effect, it will cause damage to the material. Utility Model Content

[0027] Combination Figures 1 to 3 As shown, the utility model provides a vacuum feeder for avoiding material blockage, which includes a shell 1, a baffle 11 and a blocking net 12.
[0028] Combination Figures 1 to 3As shown, the shell 1 includes a feed port, a discharge port and a vacuum generator connection port; the upper surface of the baffle 11 is an arched surface, and the design of the arched surface can prevent materials from remaining on the baffle 11. The baffle 11 is horizontally fixed above the discharge port. Only one side of the baffle 11 is fixed to the shell 1, and the distance between the unfixed side of the baffle 11 and the inner wall of the shell 1 does not exceed the radius of the discharge port. The design of the distance between the unfixed side of the baffle 11 and the inner wall of the shell 1 can control the accumulation of materials above the discharge port; the blocking net 12 is located between the feed port and the vacuum generator connection port. Between the interfaces, the blocking net 12 is vertically located above the baffle 11, and the bottom edge of the blocking net 12 is lower than the vacuum generator connection port, and the side of the blocking net 12 is fitted and fixedly connected to the inner wall of the shell 1. The blocking net is designed to prevent material accumulation at the suction port of the vacuum generator to affect the suction effect; the baffle is designed to control the volume of material entering the discharge port, and the material only enters the discharge port through the gap between the edge of the baffle and the inner wall. The channel for the material to enter the discharge port is narrow and long, and the material will only accumulate a small amount against the inner wall, avoiding the problem of large accumulation of material at the discharge port, thereby avoiding the occurrence of blockage.
[0029] In some embodiments, in combination Figure 2 As shown, the shell 1 also includes an upper flip cover 13, and an observation window is opened on the top plate of the shell 1. The observation window is rotatably connected to the upper flip cover 13. The feed port and the vacuum generator connection port are respectively designed on two opposite side walls of the shell 1. After the upper flip cover 13 is set up, the interior of the shell 1 can be directly observed by opening the upper flip cover 13. When the operation of the vacuum feeder to avoid material blockage fails, the problem can be quickly discovered, which greatly facilitates the subsequent maintenance problems.
[0030] In some embodiments, in combination Figure 1 As shown, the vacuum loader for avoiding material blockage also includes a vacuum generator 2, and the vacuum generator 2 is connected to the shell 1 through the vacuum generator connection port. The vacuum generator 2 is a power element for generating negative pressure in the shell 1. The external vacuum generator 2 can make it unnecessary to consider the volume problem. The suction force of the vacuum loader for avoiding material blockage can be increased by using a vacuum generator 2 with a larger volume and greater power.
[0031] In some embodiments, in combination Figure 1 As shown, the vacuum loader for avoiding material blockage also includes a vibration motor 3, which is fixedly connected to the bottom surface of the baffle 11, and the vibration motor 3 is away from the fixed edge of the baffle 11. The vibration motor 3 can speed up the speed of material separation from the baffle 11 and reduce the possibility of material blockage. The vibration motor 3 is away from the fixed edge of the baffle 11 to increase the influence of the vibration motor 3 on the baffle 11.
[0032] In some embodiments, in combination Figure 1 As shown, one side of the baffle 11 close to the vacuum generator connection port is a fixed side. By designing the fixed side of the baffle 11, the distance between the feed port and the baffle 11 and the shell 1 can be made closer, thereby improving the smoothness of material movement.
[0033] In some embodiments, in combination Figure 1 As shown, the bottom surface of the shell 1 is funnel-shaped, and the center of the funnel is the discharge port. The funnel-shaped bottom surface design of the shell 1 can prevent the material from remaining on the bottom surface of the shell, and the funnel-shaped bottom surface can effectively gather the material to the discharge port.
[0034] In some embodiments, in combination Figure 1 As shown, the side of the baffle 11 is provided with a draft angle. Due to the thickness of the baffle 11, the angle of the arched top surface of the baffle 11 is relatively small. In order to improve the guiding effect of the baffle 11 on the material, a draft angle is provided on the side of the baffle 11. The side with the draft angle is used to further guide the material close to the interval, thereby improving the smoothness of the movement of the material inside the loader.
[0035] In some embodiments, in combination Figure 1 As shown, the vacuum feeder for avoiding material blockage also includes an electric valve 4 for the feed port, and the electric valve 4 for the feed port is fixedly installed at the feed port. The main function of the electric valve 4 for the feed port is to control the feeding process.
[0036] In some embodiments, in combination Figure 1 As shown, the vacuum feeder for avoiding blockage also includes an electric valve 5 for the discharge port, and the electric valve 5 for the discharge port is fixedly installed at the discharge port. The main function of the electric valve 5 for the discharge port is to control the discharge process and to prevent the reverse entry of air into the discharge port during the feeding process to affect the suction of the feeding port.
[0037] Working process: the vacuum generator 2 is started, the electric valve 4 of the feed inlet is opened, and the electric valve 5 of the discharge port is closed, so that the air pressure in the shell 1 is reduced, and the air pressure difference forms an airflow to suck the material from the feed inlet; the material entering the shell 1 will fall onto the baffle 11, and then fall to the discharge port through the gap between the outer contour of the baffle 11 and the shell 1. Since the electric valve 5 of the discharge port is closed, the material will accumulate here again. The design of the baffle 11 can make the material accumulate only along the side wall of the shell 1, and will not accumulate in large quantities above the discharge port to cause blockage. Subsequent materials will accumulate above the baffle 11; at the same time, the accumulated materials will not approach the air intake port of the vacuum generator 2 under the action of the blocking net 12, ensuring the smoothness in front of the air intake port of the vacuum generator 2 and preventing the material from blocking the air intake port of the vacuum generator 2.
[0038] The vacuum generator 2 is closed, the electric valve 4 of the feed inlet is opened, and the electric valve 5 of the discharge port is opened. At this time, there is less material above the discharge port, which avoids the blockage of the discharge port due to material accumulation. During the discharge process at the discharge port, the material above the baffle 11 will pass through the gap between the baffle 11 and the inner wall of the shell 1 and continuously move toward the discharge port. At the same time, due to the existence of the baffle 11, the movement speed will be limited to avoid material accumulation.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
