Description

Technical Field

[0001] The utility model belongs to the field of cardboard box nailing machines, and in particular relates to a wire feeding device used for a box nailing machine. Background Art

[0002] With the rapid development of the logistics industry, the packaging industry is also developing rapidly. The packaging of articles is inseparable from cartons. In order to facilitate transportation, cartons are generally folded before use, which can reduce the space occupied. The folded cartons need to be nailed at the opening before leaving the factory so that they can be quickly packaged when used. The carton board nailing machine can quickly nail the carton boards. Since the carton board nailing machine needs to perform continuous nailing, traditional nails cannot be used. A very long steel wire is cut into a specific length of steel wire and then bent, and then nailed. Therefore, the very long steel wire needs to be continuously transported to the cutting and bending mechanism, which requires adding a wire feeding device to the carton board nailing machine. In view of this, the present utility model is specially proposed. Utility Model Content

Third slide rails 17 for sliding special-shaped parts 16 are provided on both sides of the bottom of the L-shaped fixing plate 1. By arranging the conveying wheel 7 and the motor to cooperate with each other, the steel wire required in the carton nailing process is continuously conveyed, and considering that the diameter of the steel wire varies according to the needs of fixation, the distance between the two conveying wheels 7 of the device can be adjusted according to the diameter of the conveying steel wire, and the two conveying wheels 7 can be driven to rotate by the driver 8 in cooperation with the motor. When the conveying wheel 7 rotates, the steel wire located between the two conveying wheels 7 will be driven to move, and the guide member is provided so that the steel wire body 9 entering the working area of ​​the conveying wheel 7 can be positioned by the guide member to prevent it from deviating left and right during the conveying process, causing the conveying wheel 7 to be unable to convey normally, and due to the presence of the first ball 14, the arc-shaped contact piece 12 of the guide member prevents the steel wire body 9 from positional displacement without hindering the conveying of the steel wire body 9.

[0033] Among them, the anti-deviation component includes a C-shaped rod 18, a positioning ring 19, an arc-shaped pressing plate 21, a second ball 22 and a positioning bolt 20.

A second ball 22 for abutting against the steel wire body 9 is provided in the middle of each arc-shaped pressing plate 21. By providing the anti-deviation component, a pre-arrangement effect is exerted on the steel wire body 9 cleaned by the brush head 26, so that the steel wire body 9 entering the working area of the brush head 26 will not be in a bent state, thereby affecting the cleaning effect. The steel wire body 9 will be sequentially arranged in a vertical state by the cooperation of the anti-deviation component and the guiding component, so as to facilitate the brush head 26 to clean the dust or attached particles on the surface of the steel wire body 9, so as to avoid the situation that the conveying wheel 7 slips due to the entry of dust and particulate matter.

[0034] Among them, a chute adapted to the outer contour of the third slide rail 17 is provided at the top of the special-shaped part 16, and a mounting bolt 23 is threadedly connected to the front end of the special-shaped part 16.

A return spring 28 abuts between the movable block 27 and the cavity, and a positioning ball 29 is installed at the side end of the movable block 27. The outer side of the positioning ball 29 abuts against the groove in the middle of the connector 25. In order to ensure the stability of the connection between the connector 25 and the T-shaped block 24 when they are clamped, the above structure is designed. When the connector 25 and the T-shaped block 24 are completely clamped, the return spring 28 will drive the movable block 27 to reset. At this time, the positioning ball 29 abuts into the groove in the middle of the connector 25 to complete the positioning.

[0036] Among them, the lower end of the multi-function box 15 is provided with a reserved hole for the installation of the dust storage bottle 30, a filter screen 31 is installed at the bottom of the dust storage bottle 30, and the top of the dust storage bottle 30 is installed with the internal thread block 37 of the multi-function box 15, and the interior of the multi-function box 15 is provided with a cavity for the installation of a small negative pressure pump 32, the negative pressure end of the small negative pressure pump 32 passes through the multi-function box 15 through the negative pressure pipe 33 and is connected to the inside of the dust collecting hopper 34, and the dust collecting hopper 34 is fixedly mounted on the outside of the special-shaped part 16, The other end of the negative pressure pump 32 passes through the internal threaded block 37 through the delivery pipe and extends to the interior of the dust storage bottle 30. By setting a small negative pressure pump 32, a dust collecting hopper 34 and a dust storage bottle 30, the dust cleaned by the brush head 26 is collected. The small negative pressure pump 32 generates negative pressure when it works. The negative pressure sucks in the dust at the open position of the dust collecting hopper 34, and then delivers it to the interior of the dust storage bottle 30 through the delivery pipe. The dust will then remain in the interior of the dust storage bottle 30, and the air will be discharged through the pores of the filter 31.

[0037] Among them, the outer part of the conveying wheel 7 is connected with a wear-resistant rubber sleeve 35, and the wear-resistant rubber sleeve 35 and the conveying wheel 7 are reinforced by a disassembly bolt 36. The provision of the wear-resistant rubber sleeve 35 increases the friction force on the surface of the conveying wheel 7, so that the friction force of the contact surface between it and the wire body 9 becomes larger, so that the conveying is more stable and slipping is avoided.

[0038] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention.
