Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a feeder. Background Art

[0002] At present, the screw feeder can be used with various specifications of extruders and high-speed mixers. The material is automatically fed from the storage box by the screw (the height can be determined by the user), and the feeding is controlled by the food processor. It has the characteristics of automatic feeding, fast feeding, labor saving, safety and reliability. The commonly used screw feeder in industry is composed of a frame, a spiral feeding tray and a vibration motor.

[0003] In the existing technology, the two ends of the main shaft in the spiral feeder are generally connected to the outer shell through bearings. As an important component in modern mechanical equipment, the main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement and ensure its rotation accuracy. The use of bearings can reduce the friction coefficient of the main shaft during rotation and make feeding smoother.

[0004] There is usually a gap when the main shaft is connected to the shell, and the feeder is usually set at an angle. When the material contains liquid, the liquid will seep out from the bottom, causing pollution to the site and corrosion to the equipment. Utility Model Content

[0040] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0041] like Figures 1-4 As shown, the loader 100 provided by the embodiment of the present invention may include a shell 110, a shaft assembly 120 and a shaft end sealing assembly 130. The shell 110 is tilted, and the shell 110 may include a lower first end 111 and a higher second end 112. A first through hole 113 is provided at the first end 111. The shaft assembly 120 is provided in the shell 110, and both ends of the shaft assembly 120 are rotatably connected to the shell 110 at the first end 111 and the second end 112. The shaft end sealing assembly 130 is provided at the first end 111 of the shell 110, extends into the shell 110 through the first through hole 113, is rotatably connected to the shaft assembly 120, and seals the first through hole 113 of the first end 111.

[0042] In this embodiment, by providing an axial end sealing assembly 130 at the first end 111 of the shell 110, the first through hole 113 of the first end 111 of the shell 110 can be effectively sealed, thereby preventing the liquid material in the shell 110 from flowing out of the first through hole 113 of the first end 111, avoiding contamination of the site where the loader 100 is located, and also avoiding corrosion of the outside of the shell 110 by the liquid.

[0043] As a specific embodiment of the present invention, the shaft end sealing assembly 130 of this embodiment may include a sealing cover plate 131 detachably connected to the outside of the housing 110 via a fastener 140 and covering the first through hole 113 to seal the first through hole 113 .

[0044] Specifically, the sealing cover plate 131 may be made of steel. The area of the sealing cover plate 131 is larger than the area of the first opening, and the sealing cover plate 131 is fastened to the housing 110 via at least three fasteners 140 .

[0045] As a specific embodiment of the present invention, the shaft end sealing assembly 130 of this embodiment may further include a first sealing member 132 . The first sealing member 132 is disposed between the housing 110 and the sealing cover plate 131 and located between the first through hole 113 and the fastener 140 .

[0046] Specifically, in this embodiment, a first sealing member 132 is further provided between the first through hole 113 and the fastener, which on the one hand improves the sealing performance between the housing 110 and the sealing cover plate 131 , and on the other hand prevents liquid leakage between the fastener and the sealing cover plate 131 .

[0047] As a specific embodiment of the present invention, the shaft assembly 120 of this embodiment may include a main shaft 121, which includes a hole 122 near the first end 111. The shaft end seal assembly 130 may include a support member 133, which is connected to the sealing cover plate 131 and extends into the housing 110 through the first through hole 113 and then engages with the hole 122.

[0048] Specifically, the support member 133 of this embodiment can be made of copper. The support member 133 is cylindrical and fits into the hole 122. The hole 122 is slightly larger than the support member 133. During the rotation of the main shaft 121, the main shaft 121 rotates relative to the support member 133.

[0049] In this embodiment, the support member 133 and the sealing cover plate 131 are also connected by a fastener 150 .

[0050] As a specific embodiment of the present invention, a second sealing member 134 is provided between the support member 133 and the sealing cover plate 131. The second sealing member 134 can seal between the support member 133 and the sealing cover plate 131 to prevent liquid from leaking out of the fastener between the sealing cover plate 131 and the support member 133.

[0051] As a specific embodiment of the present invention, a second through hole 114 may be provided at the second end 112 of the housing 110. The loader 100 may further include a connecting assembly 160. Connecting assembly 160 is disposed at the second end 112 of the housing 110. After the spindle 121 passes through the second through hole 114, the connecting assembly 160 rotatably connects the spindle 121 to the housing 110.

[0052] More specifically, the connection assembly 160 of this embodiment may include a bearing 161 and a fixing member 162. Bearing 161 is disposed on the housing 110, and the main shaft 121 passes through the bearing 161 and is rotatable relative to the bearing 161. Fixing member 162 is fixed to the main shaft 121 and is located above the bearing 161 to prevent the main shaft 121 from moving downward relative to the bearing 161, thereby ensuring that the lower end of the main shaft 121 maintains a certain distance from the sealing cover plate 131.

[0053] Specifically, in this embodiment, the main shaft 121 is rotatably connected to the housing 110 through the connecting assembly 160, and the main shaft 121 is supported by the fixing member 162, thereby ensuring that there is a certain distance between the lower end of the main shaft 121 and the sealing cover plate 131, thereby preventing the lower end of the main shaft 121 and the sealing cover plate 131 from contacting each other, so that the main shaft 121 causes damage to the sealing cover plate 131 or the main shaft 121 when rotating.

[0054] In addition, in this embodiment, the lower end of the main shaft 121 is supported by a support member 133, which also prevents the main shaft 121 from abutting against the sealing cover plate 131. The support member 133 can be made of copper, while the main shaft 121 is typically made of steel. Therefore, when the main shaft 121 rotates relative to the support member 133, only the support member 133 is subject to wear. Regular replacement of the support member 133 can ensure a good seal, minimize leakage, and reduce wear on the housing or sealing cover plate 131.

[0055] Specifically, the material loader 100 of this embodiment may further include a drive assembly 170 and a transmission assembly 180. The drive assembly 170 is used to output power and includes an output shaft 171. The transmission assembly 180 may include a sprocket 181 and a chain 182. The sprocket 181 is disposed at the end of the main shaft 121. The chain 182 is disposed between the output shaft 171 and the sprocket 181. The drive assembly 170 drives the output shaft 171 to rotate, thereby driving the chain 182 and the sprocket 181 to rotate, thereby driving the main shaft 121 to rotate.

[0056] Specifically, the drive assembly 170 and transmission assembly 180 of this embodiment are disposed at the second end 112 of the housing 110. The drive source of the drive assembly 170 of this embodiment may be a motor. The motor rotates, driving the chain 182. The chain 182 rotates the sprocket 181, which in turn rotates the main shaft 121. The shaft assembly 120 also includes blades 123 disposed on the main shaft 121. As the main shaft 121 rotates, the blades 123 rotate continuously, thereby transporting the material from bottom to top.

[0057] As a specific embodiment of the present invention, a third opening is further provided above the housing 110 of this embodiment, and a cover plate 115 is further provided at the third opening to cover the third opening. The housing 110 is also provided with a feed port 116 and a discharge port 117. The feed port 116 is located above the housing 110 near the first end 111, and the discharge port 117 is located below the housing 110 near the second end 112.

[0058] Specifically, the structure and main operating principle of the loader 100 of this embodiment are:

[0059] The spindle 121 is disposed within the housing 110. The lower left end of the spindle 121 is connected to the first end 111 of the housing 110 via a shaft end seal assembly 130. Fasteners connect the sealing cover plate 131 to the housing 110. A support member 133 passes through the first through-hole 113 and engages with the hole 122 at one end of the spindle 121. The other end of the spindle 121 passes through the second end 112 of the housing 110 and is connected to the drive assembly 170 via the transmission assembly 180. The drive assembly 170 drives the spindle 121 to rotate.

[0060] During use, materials are fed into the feed port 116 . When the main shaft 121 rotates, the blades 123 rotate to continuously transport the materials upward, and finally the materials are discharged from the discharge port 117 .

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
