A baling steel belt conveyor

Abstract

This utility model relates to the technical field of packaging equipment, specifically a steel strapping conveyor device. It includes a frame, a steel strapping reel, a power unit, a lifting device, and a control system. The frame consists of two interconnected cross-shaped structures, with a steel strapping reel positioned between each cross. The power unit is a geared motor located below the cross to drive the steel strapping reel's rotation. The control system controls the operation of the power unit. The lifting device is fixed to one side of the frame and includes a lower nylon wheel assembly and an upper nylon wheel assembly with identical structures. Both consist of multiple rotatable nylon wheels with side guards. The lower and upper nylon wheel assemblies form a pulley system lifting mechanism. The steel strapping connects the two assemblies, essentially storing the strapping between them. When the packaging machine draws the strapping, the geared motor starts releasing the steel strapping when the lower nylon wheel assembly rises to the upper detector position, and stops when the lower nylon wheel assembly descends to the lower detector position. This cycle repeats continuously.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Appendix Figure 1 As shown in Figure 7, a steel strapping conveying device includes a frame 1, a steel strapping reel 13, a power unit, a lifting device, and a control system. The frame 1 consists of two crosses connected together, with a steel strapping reel 13 disposed in the middle of each cross. The power unit is located below the crosses to drive the steel strapping reel 13 to rotate. The lifting device is fixed to one side of the frame 1 and is used to store a portion of the steel strapping pulled out from the steel strapping reel 13. The control system controls the operation of the power unit.

[0026] Preferably, an L-shaped protective frame 12 is installed on the frame 1 between the two steel strip reel frames 13 to protect against injury from ejected steel strips.

[0027] Preferably, the power unit includes a geared motor 9 fixed below the cross intersection point at the center of the frame 1. After the geared motor 9 passes through the cross intersection point axially, a pressure bearing 10-1 is installed on the shaft of the geared motor 9. A turntable 10 is fixed on the pressure bearing 10-1, and a steel strip frame 13 is fixed on the turntable 10. The turntable 10 is fixedly connected to the shaft of the geared motor 9.

[0028] Preferably, the geared motor 9 is connected to a rotary frequency converter for controlling the speed.

[0029] Preferably, the steel strip frame 13 is composed of two discs connected by a central tube.

[0030] Preferably, four casters 10-2 are provided on the cross below each steel strip reel frame 13 to support the steel strip reel frame 13.

[0031] Preferably, the lifting device includes two columns 2 fixed at one end of the two crosses, each column 2 has a first guide steel ring 11 fixed at its top, and several second guide steel rings 7 at a certain angle to the ground fixed vertically on the side of the column 2. A detector fixing plate 10-3 is vertically fixed on the outer surface of the column 2, and a slide rail 3 is fixed on the detector fixing plate 10-3. A slide seat 4 is mounted on the slide rail 3, and a lower nylon wheel assembly 6 is fixed on the slide seat 4. An upper nylon wheel assembly 8 is fixed on the top of the column 2 above the lower nylon wheel assembly 6. An upper detector 16 is fixed on the upper side of the detector fixing plate 10-3, and a lower detector 15 is fixed on the lower side for detecting the position of the lower nylon wheel assembly 6.

[0032] Preferably, the first guide ring 11 and the second guide ring 7 have the same structure, which are circular steel rings with an inward arc-shaped protrusion on the inner wall of the hole.

[0033] Preferably, the lower nylon wheel assembly 6 and the upper nylon wheel assembly 8 have the same structure, including a U-shaped plate 6-4, a nylon wheel shaft 6-5 fixed on the side plate of the U-shaped plate 6-4, a plurality of nylon wheels 6-1 with side guards arranged side by side fixed on the nylon wheel shaft 6-5, a bearing 6-3 is provided at the center of the nylon wheel 6-1 with side guards, and the bearing 6-3 is fixed on the nylon wheel shaft 6-5;

[0034] The U-shaped plate 6-4 has an anti-detachment wheel axle 6-6 on the outside of the nylon wheel 6-1 with a flange, which is parallel to the nylon wheel axle 6-5. Multiple anti-detachment wheels 6-2 are installed on it, each anti-detachment wheel 6-2 corresponding to a nylon wheel 6-1 with a flange, and the anti-detachment wheel 6-2 is inserted into the flange of the nylon wheel 6-1 with a flange, so as to prevent the steel belt 5 from detaching.

[0035] In use, multiple steel strip reels 14 are clamped on the steel strip reel frame 13 at one time. The steel strip 5 comes out of the steel strip reel, passes through the second guide steel ring 7, enters the first nylon wheel 6-1 with a side guard at one end of the upper nylon wheel assembly 8, then wraps around the first nylon wheel 6-1 with a side guard on the same side of the lower nylon wheel assembly 6, then wraps around the second nylon wheel 6-1 with a side guard on the upper nylon wheel assembly 8, then wraps around the second nylon wheel 6-1 with a side guard on the lower nylon wheel assembly 6, and finally passes through the last nylon wheel 6-1 with a side guard on the upper nylon wheel assembly 8, and then connects to the baling machine through the first guide steel ring 11.

[0036] When the strapping machine pulls out the strap, the lower nylon wheel assembly 6 begins to rise from the lower detector 15. When the lower nylon wheel rises to the upper detector 16, the upper detector 16 sends a signal to the control system. The control system controls the reduction motor 9 to start rotating. At this time, the steel belt 5 is released outward from the steel belt reel 14, and the lower nylon wheel assembly 6 will slowly descend until the lower detector 15 detects the lower nylon wheel assembly 6. At this time, the reduction motor 9 stops rotating. This cycle continues to ensure the normal operation of the strapping machine.

[0037] Because the diameter of the steel belt reel 14 changes significantly during use, the rotary frequency converter connected to the motor can adjust the linear speed of the belt reel rotation in a timely manner according to the site conditions.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
