Description

Technical Field

[0001] The utility model relates to the technical field of fastener production equipment, in particular to a steel strip machine equipment used for gluing fasteners. Background Art

[0002] Chemical glue used for fasteners and screws is usually called fastening glue or anaerobic sealant. This glue is mainly used to ensure that the screws do not fall off during operation.

[0003] Liquid chemical glue is applied to the threaded surface of the fastener. Usually, a glue drip nozzle is set vertically above the fastener, and the liquid chemical glue is naturally dripped onto the threaded section of the fastener. The fastener is then sent to the drying equipment to dry the chemical glue, completing the gluing process.

[0004] In order to facilitate the reception of liquid chemical glue, the fasteners are designed with a conveying device that conveys the fasteners in a horizontal position to the bottom of the glue drip nozzle. This results in the fasteners remaining in a horizontal position when the conveying device continues to convey the fasteners into the drying equipment.

[0005] At this time, under the action of gravity and drying air, the liquid chemical glue on the horizontal fastener will drip from the threaded section, causing problems such as uneven coating and the chemical glue being blown off.

[0006] Therefore, the existing technology adopts the method of setting magnets on the steel belt to absorb the fasteners and transmit the fasteners. As shown in the attached figure of the specification, the steel belt rotates under the tension and transmission of the steel belt pulleys on both sides, and a guide wheel group is set at the work station where the drying equipment is located to guide the steel belt to twist 90°. The originally vertical steel belt (corresponding to the fasteners in the horizontal posture adsorbed) is guided to twist into a horizontal posture (the fasteners are in a vertical state with the twisting), so that the fasteners form a posture change at the work station where the drying equipment is located, thereby improving the drying process effect, and then guided back to the initial posture through another set of guide wheel groups. The fasteners continue to follow the steel belt rotation to enter the subsequent process equipment until the finished product is separated from the steel belt.

[0007] The problem with the existing technology is that the steel belt is relatively thin in order to rotate and twist. Although it is guided and limited by the tensioning wheels and guide wheel groups on both sides, the steel belt will vibrate during the transmission process. Especially at the work station where the glue dripping mechanism is located, if horizontal vibration occurs, it will cause the transmission trajectory of each fastener on the steel belt to fluctuate and deviate. At this time, the position of the glue dripping mechanism is fixed, which results in the liquid chemical glue not dripping on the threaded segment specified by the process. For example, if the process specifies to apply chemical glue between a certain number of teeth, the dripping form is difficult to meet such precise requirements.

[0008] Therefore, it is necessary to improve the design of the steel belt machine equipment to avoid unnecessary vibration of the steel belt at the glue dripping station in order to stabilize the quality of the glue coating process. Utility Model Content

[0009] In order to solve the deficiencies of the above-mentioned technology, the utility model provides a steel strip machine device for gluing fasteners.

[0011] By adopting the above technical solution, a guide groove of the correction seat is set at the glue dripping station. When the steel belt passes through the guide groove, the steel belt is limited by utilizing the contour adaptation of the two and the rigidity of the guide groove to avoid vibration of the steel belt, thereby ensuring that the fastener passing through the opening is in a smooth rotation trajectory, and the chemical glue is dripped into the specified thread segment position according to the process.

[0012] A further configuration of the present invention is that a plurality of rollers are rotatably arranged in the groove, the plurality of rollers are aligned and arranged in a row, and the rollers are made of magnetic material, and the plurality of rollers attract bar magnets close to the outer peripheral surface of each roller.

[0013] By adopting the above technical solution, the roller is made of magnetic material. When the steel belt passes through, the bar magnet will be attracted by one side of the roller, so that it is uniformly close to the end face of one side of the roller to form a support, thereby further improving the stability of the steel belt in the glue dispensing station.

[0014] The present invention is further provided with: the glue dripping mechanism further comprises a drip nozzle fixing seat, a base, a lifting adjustment mechanism, and a horizontal adjustment mechanism; the lifting adjustment mechanism comprises a first screw rod, a first guide rod, a lifting seat and a first hand wheel; the lifting adjustment mechanism is vertically arranged on the base to drive the lifting seat to slide vertically;

[0016] The drip nozzle fixing seat is connected to the horizontal adjustment mechanism. A plurality of drip nozzle mounting holes are provided on the drip nozzle fixing seat. The glue drip nozzle is fixed in the drip nozzle mounting hole and extends vertically above the threaded section of the fastener passing through the glue dripping station.

[0017] By adopting the above technical solution, the fixed position of the glue drip nozzle is controlled by the lifting adjustment mechanism and the horizontal adjustment mechanism, so that the dripping chemical glue is at the specified position, and cooperates with the other mechanisms to provide the accuracy of chemical glue coating.

[0018] The utility model is further configured as follows: a guide seat is provided between the feeding track and the outer side surface of the steel strip, and the guide seat is provided with a vertical slide rod, an upper limit plate, and a lower limit plate. The upper limit plate and the lower limit plate are both provided with sliding holes and positioning bolts.

The gap is parallel to the adjacent bar magnets and is positioned relative to them. The fastener is guided to the outer peripheral surface of the steel strip through the gap.

[0019] By adopting the above technical solution, the guide seat is set to guide the position of the fastener when it is adsorbed by the steel belt, and the guide fastener is aligned parallel to the bar magnet so that it can pass through the correction seat and standardize the position of each fastener.

[0020] The beneficial effect of the present invention is that the stability of the steel belt at the glue dripping station is improved and the position of the glue dripping mechanism can be adjusted by coordinating the structural characteristics of the correction seat, the glue dripping mechanism and the guide seat with the steel belt and the bar magnet.

The vibrating plate transmits the fastener 6 to the outer side surface 12 of the steel belt 1 through the feeding track 2 and is adsorbed. The driving mechanism drives the steel belt pulley 3 to drive the steel belt 1 Rotation; the steel strip 1 is provided with a glue dripping station, which is provided with a correction seat 7, and the correction seat 7 is provided with a guide groove 71 adapted to the contour of the steel strip 1 along the rotation direction, and the guide groove 71 is provided with an opening 72 for the fastener 6 on the outer side surface 12 of the steel strip 1 to pass through, and a groove 73 for the bar magnet 11 on the inner side surface of the steel strip 1 to pass through. The glue dripping mechanism 5 is provided at each glue dripping station, including a drip nozzle fixing seat 52 and a glue drip nozzle 51, and the glue drip nozzle 51 is located vertically above the fastener 6 passing through the opening 72.

[0031] By setting a guide groove 71 of the correction seat 7 at the glue dripping station, when the steel belt 1 passes through the guide groove 71, the steel belt 1 is limited by utilizing the contour adaptation of the two and the rigidity of the guide groove 71 to avoid vibration of the steel belt 1, thereby ensuring that the fastener 6 passing through the opening 72 is in a smooth rotation trajectory, and the chemical glue is dripped at the specified thread segment position according to the process.
