Description
Technical Field
[0001] The utility model relates to the technical field of baling machines, in particular to a wire feeding guide device for baling machines. Background Art
[0002] After waste paper and waste plastics are recycled, they need to be packaged using a baler to reduce their volume for easy storage and transportation. Among them, the horizontal baler is one of the commonly used large-scale baling equipment, which compresses the continuously input materials, and after each compression completes a fixed volume of material bag, it uses steel wire to bundle it, and then outputs the material bag after bundling. In the field of waste paper and waste plastic recycling, the material bags that are punched out are mostly large bags with a side length of 1m or more. The steel wire used for bundling must be at least 5mm in diameter to meet the bundling strength requirements. Fig. 9 As shown, the steel wire is placed on a wire unwinding rack in the form of a wire coil. When feeding the wire, the steel wire is unwinded upward and is converted into an approximately straight state in the horizontal direction through a guide device directly above, and then reaches the baler for use.
[0003] Among them, the wire feeding at the wire feeding rack is produced by active wire drawing at the baler. However, in actual operation, it is found that this steel wire with a larger diameter, because it was originally in a coiled state in the wire roll, will form a spiral-like bending state after being passively drawn out. The wire drawing process will be accompanied by violent swinging of the steel wire. As a result, the relatively narrow wire passage at the guide device will be blocked or even stuck, resulting in unstable wire drawing and wire drawing failing to reach the specified length. In severe cases, the bundling action cannot complete normal knotting. In addition, the dust pollution in the waste paper and waste plastic packaging occasions is very obvious. After running for a period of time, obvious scale will be generated in the guide device, and the scale will cause the guide wheel to rotate poorly, which will further aggravate the blockage and jamming at the guide device. For this reason, it is necessary to improve the wire feeding guide device to improve the above situation. Utility Model Content

DETAILED DESCRIPTION
[0022] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0023] like Figures 1 to 8 As shown in the figure, the wire feeding guide device for the baler includes a bracket 1, a hanging rod 2 is vertically installed on the bracket 1, a hanging hole 3 is provided on the bracket 1 to be gap-matched with the hanging rod 2, and a guide box 4 is fixed at the lower end of the hanging rod 2. Figures 5 to 8 As shown, the hanging rod 2 and the hanging hole 3 are clearance-matched, so that the guide box 4 can have good rotation and swing freedom. Among them, the hole length of the hanging hole 3 should be as small as possible so that the guide box 4 can have an ideal swing amplitude. This embodiment is illustrated by opening the hanging hole 3 on a certain angle steel part of the bracket 1.
[0024] The hanging rod 2 includes a hanging screw 21 fixedly arranged on the top of the guide box 4, and the fixing arrangement here can be directly realized by welding. The hanging screw 21 passes through the hanging hole 3 upward and is loosely matched with the hanging hole 3. A falling stop nut 22 is fixedly installed on the hanging screw 21 above the hanging hole 3, and the falling of the hanging screw 21 is limited by the falling stop nut 22.
[0025] Preferably, an upward floating stop nut 23 is fixedly mounted on the hanging screw 21 below the hanging hole 3, and the upward floating stop nut 23 limits the floating of the hanging screw 21 to prevent the guide box 4 from colliding with the steel wire 9 when the guide box 4 floats upward. The distance between the upward floating stop nut 23 and the downward stop nut 22 is greater than the length of the hanging hole 3, so that the hanging screw 21 can swing relative to the hanging hole 3, that is, the guide box 4 realizes its swinging freedom.
[0026] The guide box 4 includes a wire inlet side 41 and a wire outlet side 42. Conventionally, the wire outlet side 42 is the side facing the baler 92, and the wire inlet side 41 is the side receiving the steel wire 9 from the wire release rack 91 below. A guide wheel 5 is rotatably mounted on the guide box 4 between the wire inlet side 41 and the wire outlet side 42 to guide the steel wire 9 released upward from the bottom to a nearly straight state in the horizontal direction. Conventionally, the guide wheel 5 is implemented by a wheel with a guide groove on the wheel surface.
[0027] A wire drawing tube 43 is vertically provided at the lower end of the wire feeding side 41, and the wire drawing tube 43 receives the steel wire 9 released by the wire releasing rack 91. After entering the wire drawing tube 43, the steel wire 9 is rigidly constrained by the tube wall and can be roughly straightened. In this straightening process, with the better rotation and swinging freedom of the guide box 4, the wire drawing tube 43 can easily always maintain a tangent or nearly tangent direction with the spiral steel wire 9, that is, the steel wire 9 can smoothly enter the wire drawing tube 43 without obvious obstruction and jamming, and the bending that may still exist after entering the wire drawing tube 43 is rigidly straightened by the wire drawing tube 43, so that the guide wheel 5 guides the smooth wire feeding.
[0028] The wire outlet side 42 is provided with a wire outlet avoidance opening 44, and a flexible dustproof structure 6 is provided in the guide box 4 at the wire outlet avoidance opening 44. Based on the fact that the wire outlet direction is basically kept in a straight direction toward the baler 92, that is, the wire outlet direction is basically unchanged, in the process that the guide box 4 passively changes its posture to adapt to the shape of the steel wire 9, the relative angle position between the guide box 4 and the output steel wire 9 also changes synchronously. In this embodiment, the wire outlet avoidance opening 44 with a larger area is adapted to the posture change of the guide box 4 to ensure smooth wire outlet.
[0029] The guide box 4 of this embodiment includes a box top plate 45 fixedly connected to the hanging rod 2, and two box side plates 46 arranged opposite to each other are fixed on the box top plate 45, and the guide wheel 5 is rotatably mounted between the two box side plates 46; a box side plate 47 is sealed and fixed between the two box side plates 46 at the wire inlet side 41, and a box bottom plate 48 is sealed and fixed between the bottom edges of the two box side plates 46, and the wire drawing tube 43 is arranged at one end of the box bottom plate 48 close to the box side plate 47, and the box top plate 45, the box bottom plate 48 and the two box side plates 46 are located at the wire outlet side 42 to jointly enclose the wire outlet avoidance opening 44. Therefore, the guide box 4 is welded by regular plates as a whole, and the processing and manufacturing is simple, and the wire outlet avoidance opening 44 is a whole-side opening, and the opening is large, which is convenient for use as an access channel for disassembly and assembly of the guide wheel 5.
[0030] Based on the above structure, the flexible dustproof structure 6 includes a dustproof side plate 61 which is respectively abutted against the inner walls of the two box side plates 46, a dustproof top plate 62 is integrally connected between the upper ends of the two dustproof side plates 61, and a dustproof bottom plate 63 is integrally connected between the lower ends, and the upper ends of the two dustproof side plates 61 are hingedly connected to the two box side plates 46; a swing avoidance gap 64 is respectively provided between the dustproof top plate 62 and the box top plate 45, and between the dustproof bottom plate 63 and the box bottom plate 48, a dustproof upper folding plate 65 abutting against the box top plate 45 is integrally bent on the inner edge of the dustproof top plate 62, and a dustproof lower folding plate 66 extending to the wire outlet side end face of the box bottom plate 48 is integrally bent on the outer edge of the dustproof bottom plate 63, and the dustproof lower folding plate 66 is screwed to the box bottom plate 48; dustproof brushes 67 are respectively provided on the two dustproof side plates 61.
[0031] The dustproof brush 67 is arranged with the dustproof side plate 61 as a carrier, and the bristles are in flexible contact with the steel wire 9, so that when the steel wire 9 changes its position at the different positions of the wire outlet 44, the dustproof side plate 61 can always maintain the dust blocking effect. The dustproof side plate 61 is first installed at the wire outlet 44 in a hinged manner, and then swung to the extent that the dustproof lower folding plate 66 is in contact with the box bottom plate 48. At this time, the dustproof upper folding plate 65 blocks the upper swing avoidance gap 64, and the dustproof lower folding plate 66 blocks the lower swing avoidance gap 64, and cooperates with the dustproof brush 67 to form a comprehensive blockage of the wire outlet 44. By tightening the dustproof lower folding plate 66 with screws, the flexible dustproof structure 6 is fixed as a whole; on the contrary, by releasing the screw fixation at the dustproof lower folding plate 66, the flexible dustproof structure 6 can swing away from the wire outlet 44 as a whole, which is convenient for the disassembly and cleaning of the guide wheel 5.
[0032] In this embodiment, the hanging rod 2 and the hanging hole 3 are clearance-matched, so that the guide box 4 can have good rotation and swing freedom, so as to facilitate the passive posture change of the spiral shape of the steel wire 9, and significantly reduce obstruction and jamming. Before the steel wire 9 enters the guide device, the wire drawing tube 43 forms a wire drawing channel, and the hard constraint of the tube wall is used to enable the steel wire 9 to change from a spiral state to a state of approximate straight line to reach the guide wheel 5, and the wire outlet side 42 adapts to the posture change of the guide box 4 with the larger wire outlet avoidance port 44, so as to achieve smooth wire outlet and smooth wire guiding. The guide wheel 5 adopts the box structure of the guide box 4, and the wire outlet avoidance port 44 is blocked with a flexible dustproof structure 6. The space inside the box is relatively closed and is less affected by dust.
