Description

Technical Field

[0001] This utility model belongs to the field of screw conveyor processing technology, and in particular relates to a screw conveyor screw cylinder feeding device. Background Technology

[0002] A screw conveyor is a feeding device that uses the driving force of a screw to transport materials. Its main structure includes screw blades, and it is classified into shafted screw conveyors and shaftless screw conveyors depending on the type of material being fed. The screw blades are rotatably connected inside a cylindrical feeding cylinder, which has an inlet structure at one end and a outlet structure at the other. After material is fed through the inlet structure, it is propelled towards the outlet structure by the rotating screw blades.

[0003] In the production of screw conveyors, the feed cylinder (commonly known as a bar cylinder) blank is fed onto the worktable of the cutting equipment. The cutting equipment (cutting wheel) cuts the feed cylinder to a specific length from the bar blank according to the dimensions of the screw conveyor being processed. However, due to the large length and very high overall weight of the bar cylinder blank, feeding it during the cutting process is quite difficult. The current method is to install rotating support rollers on the worktable, which are driven by rolling friction.

[0004] However, for bar billets, the length and weight of the billets in this province are significant, making them very difficult to move. During the moving process, it is also necessary to maintain the straight movement of the billet, prevent the end of the billet from tilting, and ensure a clean cut. Therefore, these various drawbacks make feeding the billet during actual processing extremely difficult. Utility Model Content

[0005] Based on the above background, the purpose of this utility model is to provide a screw conveyor screw cylinder feeding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A screw conveyor screw cylinder feeding device includes a pushing bracket for pushing bar cylinder blanks, and a plurality of support shaft structures for supporting bar cylinder blanks are rotatably connected to both sides of the pushing bracket.

[0008] It also includes a pushing structure for pushing the bar billet, wherein the bar billet includes a pusher bracket that pushes the bar billet at the end position;

[0009] The push bracket is slidably connected to the push bracket;

[0010] The push bracket is pulled by a traction rope structure.

[0011] Preferably, the pusher includes a support base, and vertically arranged vertical parts are fixedly connected to the top two sides of the support base, and a support shaft structure is rotatably connected to each vertical part.

[0012] Preferably, the support shaft structure includes a support shaft rotatably connected to the vertical part, and a partition flange of the partition rod blank is welded onto the support shaft;

[0013] The two support shafts are spaced apart.

[0014] Preferably, the support base has an elongated sliding opening, and the push support includes a vertical portion that extends through the elongated sliding opening;

[0015] A downward sliding crossbeam is fixedly connected to the bottom of the vertical part of the bracket.

[0016] The two ends of the lower sliding crossbeam are slidably connected to guide rails, and the bottom sides of the bracket base are fixedly connected to fixed brackets that are fixedly installed at both ends of the guide rails.

[0017] Preferably, the bottom ends of the lower sliding crossbeam are respectively fixedly connected to slide blocks, and the guide rail is slidably connected to the slide blocks.

[0018] Preferably, a horizontally arranged push plate is fixedly installed on the side of the vertical part of the bracket facing the bar billet.

[0019] Preferably, the traction rope structure includes traction motors spaced apart on both sides, a rope winding wheel fixedly mounted on the output shaft of the traction motor, a traction steel cable wound on the rope winding wheel, and steel cable pull rings fixedly connected to the side walls on both sides of the vertical part of the bracket, with the traction steel cable hanging on the steel cable pull rings.

[0036] Example 1

[0037] like Figure 1-5 As shown, a screw conveyor screw cylinder feeding device includes a pushing bracket for pushing bar cylinder blanks 3. The pushing bracket has the following structure: the pushing bracket includes a bracket base 21, and vertically arranged vertical parts 22 are fixedly connected to the front and rear sides of the top of the bracket base 21. Several support shaft structures for supporting bar cylinder blanks 3 are rotatably connected. The support shaft structures on the front and rear sides are spaced apart to leave sufficient space (the pushing bracket described below needs to penetrate through this space).

[0038] Specifically, the support shaft structure includes a support shaft 6 rotatably connected to the vertical part 22 (in the conventional manner, a mating bearing is installed on the vertical part 22), and an annular partition flange 61 for blocking the bar billet 3 is welded onto the support shaft 6. The bar billet 3 is placed and supported between the support shafts 6, and the annular partition flange 61 blocks the bar billet 3 to prevent the billet from tilting during horizontal pushing, which would affect processing.

[0039] To facilitate easy and linear movement of the heavy, long bar billet 3, the aforementioned structure further includes a pushing mechanism for the bar billet 3. The bar billet 3 includes a pusher bracket positioned at its right end. Specifically, the pusher bracket includes a vertical portion 51, and correspondingly, a long sliding opening is provided on the bracket base 21. The vertical portion 51 extends through the long sliding opening.

[0040] Meanwhile, a lower sliding crossbeam 512 is fixedly connected to the bottom of the vertical part 51 of the bracket; guide rail rods 8 are slidably connected to the front and rear ends of the bottom of the lower sliding crossbeam 512 (the specific sliding method is: slide blocks 5121 are fixedly connected to the bottom ends of the lower sliding crossbeam 512, and the guide rail rods 8 are slidably connected to the slide blocks 5121). Correspondingly, fixed brackets 81 (L-shaped brackets are fastened by bolts) are fixedly connected to the front and rear sides of the bottom of the bracket base 21.

[0041] Meanwhile, in order to realize the automatic movement of the bar cylinder blank 3, the above-mentioned push support is pulled by the traction rope structure.

[0042] The pulling and pushing bracket is achieved through a traction rope structure. During the pulling and pushing process, the vertical part 51 of the bracket abuts against the end of the bar billet 3, continuously pushing the heavy bar. In this process, since the bar billet 3 is supported on the rotating support shaft 6 structure, the bar billet 3 can be pushed in a labor-saving manner with the support of the support shaft 6 structure.

[0043] Example 2

[0044] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, in order to smoothly push the bar billet 3, a horizontally arranged push plate 52 is fixedly installed on the side of the vertical part 51 of the bracket facing the bar billet 3. Specifically, a screw is fixed at the center of the push plate 52, and the screw passes through the vertical part 51 of the bracket and is tightened with a nut.

[0045] Example 3

[0046] like Figure 1-5 As shown, this embodiment, based on the structure of embodiment 2, includes a traction motor 42 spaced apart on both the front and rear sides. A rope winding wheel 41 is fixedly mounted on the output shaft of the traction motor 42, and a traction steel cable 43 is wound on the rope winding wheel 41. Steel cable pull rings are fixedly connected to the side walls on both sides of the vertical part 51 of the support (specifically, a pull rod is welded to the side walls on both the front and rear sides of the vertical part 51 of the support, and a hanging ring 511 is welded to the end of the pull rod. A buckle is fixedly connected to the wire rope, and the buckle is hooked onto the pull ring 511). The traction steel cable 43 is hung on the steel cable pull ring. During the pulling process, the pushing support slides through the guide rail at its lower end, thus increasing the stability of the pushing and sliding.

[0047] The traction motor 42 is fixedly installed at one end (i.e., the left side) near the cutting station, so that the two traction motors 42 work synchronously during the operation. The synchronous winding rope wheel 41 pulls the traction steel cable 43. During the pulling process, the pusher bracket pushes the barrel to move.

[0048] The simultaneous operation of the two traction motors 42 is a conventional method disclosed in the prior art. For example, the two motors are powered on and operate synchronously after the main switch on the circuit is closed.

[0049] The model of the aforementioned traction motor 42 is determined based on the actual processing of the bar blank 3. If the bar has a large diameter and long length, a motor with greater traction force should be selected.

[0050] The motor is fixed in the following way:

[0051] According to the existing method, a steel structure bracket 1 is fixedly installed between the bottoms of the support base 21; a motor bracket is fixedly installed at the bottom of the traction motor 42, and the motor bracket is fixedly installed at the top position of the support base 21.

[0052] Example 4

[0053] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 3, and is the same as the existing method. A cutting device, such as a cutting machine, is set on the left side (discharge end) of the entire device. When the bar billet 3 is drawn into the cutting device to the moving length, it is cut. After the entire bar is cut, the motor unwinds the traction cable 43 and slides the pusher bracket back to the right side, waiting for the next push of the bar.

[0054] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
