Technical Field

[0001] The utility model relates to a rotary feeding device, belonging to the technical field of chemical production equipment. Background Art

[0002] In chemical production, the process of transferring liquid materials between different containers is often involved, such as the transfer between different drums during production, and the transfer from the drum to the packaging drum during finished product packaging. During actual operation, generally, the raw material drum is first installed on the lifting feeder, the raw material drum is lifted until its height exceeds the height of the drum to be filled, and then the liquid outlet valve of the raw material drum is opened to allow the material in the raw material drum to automatically flow into the drum to be filled. For viscous materials, an extrusion device is also required to forcibly extrude the viscous material in the raw material drum. When the existing lifting feeder is used for material transfer operation, the material dumping position is fixed, and only one drum to be filled can be placed at the material dumping position. After the drum is filled and removed, another drum needs to be replaced for operation. When packaging small-capacity drums, frequent drum replacement operations are required, increasing the working intensity of workers and reducing production efficiency.

[0003] Therefore, there is an urgent need for a lifting feeder with a simple structure, multiple material dumping positions, no need for frequent drum replacement, and high production efficiency. Summary of the Invention

[0025] Refer to Figures 1 to 6 , a rotary feeding device related to the present utility model includes a base 1, a column 2 vertically fixed on the base 1, a square column 3 rotatably sleeved on the column 2, a movable sleeve 4 vertically arranged on the square column 3, and a barrel cover 5 fixedly installed on the movable sleeve 4 through a cantilever 6; the barrel cover 5 is connected to a barrel 11 through a movable clamp 10, and the movable clamp 10 includes a C-shaped seat 101, a pressing block 102 hinged and connected to the upper end of the C-shaped seat 101 through a connecting block 104, and a pressing bolt 103 screwed on the connecting block; the pressing bolt 103 abuts against the back of the pressing block 102, and tightening the pressing bolt 103 can lock the barrel 11 on the barrel cover 5 to form a whole; further, an extrusion device 12 for extruding viscous materials to quickly discharge is provided on the barrel cover 5, including an extrusion cylinder 121 fixedly installed on the barrel cover 5 and a pressing disc 122 located below the barrel cover 5 and connected to the movable end of the extrusion cylinder 121. By extruding the viscous materials in the barrel 11 through the pressing disc 122, the viscous materials can quickly flow out of the barrel 11, improving its discharge speed;

[0026] Since the overall height of the column 2 is relatively high, for the convenience of manufacturing and simplifying the installation operation, the column 2 is designed as a first column 21 and a second column 22 fixedly connected up and down. Plain bearings 23, ball bearings 24 and tapered bearings 25 are respectively arranged at the upper, middle and lower parts of the column 2. Among them, the plain bearing 23 is arranged between the upper part of the first column 21 and the top of the square column 3, the ball bearing 24 is arranged between the upper part of the second column 22 and the middle part of the square column 3, and the tapered bearing 25 is arranged at the bottom of the second column 22 and the square column 3. The square column 3 is rotatably connected to the column 2 through three bearings;

[0027] A hook 7 is installed on the upper part of the square column 3. The hook 7 hooks the cantilever 6, and the movable sleeve 4 and the bucket cover 5 are driven by an electric hoist to move up and down along the square column 3. A locking mechanism 9 for locking the lifting position of the movable sleeve 4 is provided between the movable sleeve 4 and the square column 3, which includes a limit strip 91 vertically fixed on the square column 3, a locking hook 92 rotatably arranged on the movable sleeve 4, a locking bolt 93 for restricting the rotation of the locking hook 92, and a lock prevention bolt 94 for restricting the loosening of the locking bolt 93. The locking hook 92 is engaged and locked with a limit groove, a limit hole or a limit tooth provided on the limit strip 91. When installing or replacing the bucket 11, first loosen the lock prevention bolt 94, pull open the locking bolt 93 to disengage the locking hook 92 from the limit strip 91, and the electric hoist drives the movable sleeve 4 to descend. After replacing the new bucket 11, drive the movable sleeve 4 to rise again. When reaching the discharging height, press the locking hook 92 against the limit strip 91, the locking bolt 93 against the locking hook 92, and close the locking bolt 93 to fix the height of the movable sleeve 4, and then the discharging operation can be carried out.

[0028] Four shafts 41 are provided inside the movable sleeve 4. Two special-shaped rollers 42 are rotatably arranged on each shaft 41. Each special-shaped roller 42 is in rolling contact with the four corner parts of the square column 3. The lifting movement of the movable sleeve 4 along the square column 3 is realized by the rotation of the special-shaped rollers 42. Thanks to the connection structure between the square column 3 and the movable sleeve 4, the square column 3 can drive the movable sleeve 4 and the bucket cover 5 to perform a synchronous circular rotation movement as a whole. Correspondingly, a circular position below the discharging port of the bucket 11 can be used as a material receiving position, greatly broadening the number of material receiving points, avoiding the problem of frequent bucket replacement caused by only one material receiving point, and improving the loading and unloading efficiency of logistics. During specific operation, a plurality of receiving buckets can be sequentially placed at the circular position of the material receiving according to needs. By rotating the square column 3, the bucket 11 can stay above each receiving bucket for discharging. After a batch of buckets are filled, the next batch is replaced without frequent replacement of a single bucket, improving the material receiving efficiency.

[0029] To form a reasonable restriction and positioning for the circumferential movement of the square column 3 and ensure that the material bucket 11 can accurately stop at different material receiving positions, a braking device 8 for restricting the rotation of the square column 3 is provided at the bottom of the square column 3, which includes a brake disc 81 fixedly installed at the bottom of the square column 3, a brake frame 82 fixedly installed on the base 1, a lever 83 hinged to the brake frame 82, and a brake pad 84 hinged to the lever 83; a cylinder 85 and a spring 86 are arranged between the lever 83 and the brake frame 82; the brake pad 84 is in surface friction contact with the brake disc 81; the cylinder 85 is a pre-stretched single-acting cylinder. In the normal unloading state, the spring 86 presses against the lever 83 to make the brake pad 84 press against the brake disc 81 to prevent the square column 3 from rotating. When the material receiving position needs to be changed, the cylinder 85 acts to resist the spring 86 and retract the lever 83, so that the brake pad 84 is separated from the brake disc 81, and the square column 3 can rotate freely. When the discharge port of the material bucket 11 reaches the corresponding material receiving position, the cylinder 85 stops acting, and the spring 86 drives the lever 83 to make the brake pad 84 press against the brake disc 81 again, so that the square column 3 stops rotating, and the material bucket 11 starts the unloading operation at this material receiving point;

[0030] In the utility model, a rotatable square column 3 is sleeved outside the column 2, and the material bucket 11 and the material bucket cover 5 are installed on a movable sleeve 4 that can rotate synchronously with the square column 3, so that the discharge port of the material bucket 11 can discharge materials at any circumferential position instead of a single discharge position, thereby increasing the material receiving positions, avoiding the problem of frequently replacing the material receiving bucket, reducing the labor intensity, and improving the production efficiency.

[0031] In addition: it should be noted that the above specific implementation manner is only an optimized solution of this patent, and any modification or improvement made by those skilled in the art according to the above concept is within the protection scope of this patent.
