Description

Technical Field

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

[0002] The lifting feeder is a machine for lifting and feeding, which is mainly used for conveying and feeding materials. It is widely used in the pharmaceutical, chemical, food and other industries. For example, in the prior art, the lifting feeder is vertically provided with a lifting column through a base, and the side wall of the lifting column is movably connected with a hopper. A first vertical driving device is provided on the top of the lifting column, and a trigger block fixedly connected to the hopper is provided at the driving end of the first vertical driving device. A second vertical driving device is also provided on the top of the lifting column, and a blocking member is provided at the driving end of the second vertical driving device. A contact switch is provided at the bottom surface of the blocking member corresponding to the trigger block. A controller is provided on the side wall of the lifting column. The first vertical driving device, the second vertical driving device, and the contact switch are all connected to and controlled by the controller. When the contact switch conflicts with the top surface of the trigger block, the controller stops the first vertical driving device, so that the lifting feeder has the advantages of flexible adjustment of the lifting height of the hopper, good applicability, and convenient use. However, when the device is in use, it is inconvenient for the user to move the device due to its certain height and weight, thereby reducing the maneuverability of the device.

[0003] To this end, a positionable fixed lifting feeder with the announcement number "CN220975574U" includes: a base plate; a panel, which is fixedly installed at the bottom of the base plate; a movable plate, which is slidably connected to the inner side of the panel, and rollers are fixedly installed around the bottom of the movable plate; a threaded sleeve, which is respectively fixedly installed inside the four sides of the base plate, and the inner side of the threaded sleeve is threadedly connected with a threaded rod, and a pad is fixedly installed at the bottom of the threaded rod; a support column, which is fixedly installed at the top of the base plate, and slide grooves are provided on both sides of the support column. The base plate, the panel, the movable plate, the roller and other structures cooperate with each other, and when in use, the roller rolls on the ground, which makes it convenient for the user to move the position of the device, thereby increasing the mobility of the device.

[0004] However, for the above-mentioned positionable fixed lifting feeder, although the material to be lifted is placed on the inner side of the discharge frame, and then the user starts the driving motor to drive the first screw to rotate, so that the first screw is threadedly connected inside the threaded block, so that the threaded block drives the discharge frame to move upward until one end of the threaded block moves to the bottom of the positioning block, and then the user opens the discharge mechanism at the bottom of the discharge frame to discharge the material, there are still the following obvious defects during use: the discharge frame is fixed vertically, and since there is no structural part for adjusting the angle of the discharge frame, the discharge angle of the discharge frame cannot be adjusted, thereby failing to feed the equipment that needs to be filled with material at different angles of the feed port.

A feeding pump 8 for filling raw materials for the lifting lower hopper 5 is provided at the end of the mobile support seat 6 and on one side of the lifting pillar 1, so that the feeding pump 8 adds the required materials into the lifting lower hopper 5, and a PLC controller for controlling the feeder is provided at the front end of the feeding pump 8, which is beneficial to the start and stop control of the drive motor 13 when the lifting lower hopper 5 is adjusted at a small angle.

[0024] The top of the lifting drive block 3 is connected to a servo motor 9 fixed to the top of the inner cavity of the lifting pillar 1, driving the lifting drive block 3 to move vertically up and down. A side of the lifting drive block 3 is provided with a limit block 10 of an L-shaped structure to ensure the stability of the lifting and lowering of the lower hopper 5. A vertical plate 11 is vertically provided on one side wall of the inner cavity of the lifting pillar 1. The two sides of the vertical plate 11 are provided with limit slides 12 that are suitable for matching the limit block 10 to limit the up and down movement of the lifting drive block 3, so that the lifting drive block 3 will not rotate with the threaded vertical rod 2 during movement. A connecting steel plate is installed on one side of the lifting drive block 3. The driving motor 13, one end of the lifting driving block 3 passes through the vertical slide groove, and one end of the lifting driving block 3 is cylindrical, and the outer surface of the cylindrical end is provided with an annular limit groove, and the driving motor 13 is provided with a rotating main board 14 on the rotating shaft, which is connected to the outer limit rotation of one end of the steel plate block, and one side of the rotating main board 14 is extended and movably sleeved on the cylindrical end of the lifting driving block 3.

[0026] Specifically, during use, the user can roll the universal moving wheel 7 on the ground to move the position of the feeder. After moving the feeder to the position where it needs to be used, the user can rotate the push screw, so that the push screw drives the bearing seat to rotate and move downward, so that the push screw can push the stable pad seat to move downward and contact the ground, thereby stably supporting the feeder. Subsequently, the feeding end of the feeding pump 8 is connected with the external storage tank, and the PLC controller is used to control the material extraction through the filling pipe 18 and inject it into the lifting hopper 5, so as to realize automatic filling of the material without manual filling of the material.

The driving motor 13 drives the rotating main board 14 to follow and perform small-angle rotation adjustment, and the lifting fixed frame 4 can synchronously follow and perform small-angle rotation adjustment, thereby realizing small-angle rotation adjustment of the lifting lower hopper 5, which can adapt to the filling of materials at filling ports with different angles. In the filling process, the stirring motor 15 drives the stirring and cleaning shaft 16 to stir and clean the inside of the lifting lower hopper 5 and rotate, which can keep the material in a moving state and is beneficial to avoid blockage in the discharge pipe during the discharge process, and at the same time avoid the occurrence of caking and residual inner wall.
