And tearing damage caused by too little / too thin glue at a relatively high folding edge part on one side of the joint is avoided.

Description

Technical Field

[0001] The utility model relates to a swing adjustment mechanism for a cuff dispensing head. Background Art

[0002] During the production of sunscreen cuffs, in order to ensure that the cuffs can fit the arm and prevent the cuffs from slipping off the arm, the cuffs are usually folded inward at the cuffs and a circle of silicone is applied at the folded seam. The silicone on the existing cuffs is usually applied by a dispensing machine. The dispensing head of the existing dispensing machine can only dispense glue in a vertical state, and the dispensing head cannot swing to adjust the angle.

[0003] However, since the folded edges of the cuffs cannot be fully fitted during actual production, it will result in less glue amount at the relatively higher folded edge part on one side of the seam, and more glue amount at the relatively lower non-folded edge part on the other side of the seam. This difference in glue amount on both sides of the seam is more obvious in the working condition where the dispensing head can only dispense glue in a vertical state. Therefore, if the dispensing head can only dispense glue in a vertical state, the difference in glue amount on both sides of the seam is too large, resulting in too little / too thin glue amount at the relatively higher folded edge part on one side of the seam, and the glue is easily torn and broken, causing a slit, which seriously affects the product quality. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a swing adjustment mechanism for a cuff dispensing head.

[0005] To solve the above technical problem, the technical solution of the utility model is: a swing adjustment mechanism for a cuff dispensing head, including a mounting frame body, on which a glue head frame body driven to swing by a driving component is hinged. The axial direction of the swing of the glue head frame body is perpendicular to the axial direction of the cuff tooling. A dispensing head with a downward injection port is fixedly connected to the glue head frame body.

[0006] Preferably, a laser sensor is arranged beside the dispensing head.

[0007] Preferably, the laser sensor is fixedly connected to a sensor frame body, the sensor frame body is hinged on the glue head frame body, and the axial direction of the hinge of the sensor frame body is parallel to the axial direction of the cuff tooling.

[0009] Preferably, the driving component includes an adjusting cylinder, the end of the cylinder body of the adjusting cylinder is hinged on a cylinder mounting plate, and the piston rod of the adjusting cylinder is hinged on the glue head frame body.

[0010] Preferably, the cylinder mounting plate is screwed onto the mounting frame.

[0011] Preferably, a connecting piece for hinged connection with the piston rod of the regulating cylinder is threadedly connected to the rubber head frame.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the dispensing head of the sleeve dispensing head swing adjustment mechanism can be swung and adjusted, and the angle of the dispensing head can be adjusted by the mechanism according to the height of the sleeve folded edge.

[0026] It should be noted that the terms used herein are only for describing specific implementation modes and are not intended to limit the exemplary implementation modes according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0027] As Figures 1 to 6 shown, the present embodiment provides a swing adjustment mechanism for a sleeve dispensing head, including a mounting frame body 1, on which a rubber head frame body 2 driven to swing by a driving assembly is hinged. The axial direction of the swing of the rubber head frame body is perpendicular to the axial direction of the sleeve tooling. A dispensing head 3 with a downward injection port is fixedly connected to the rubber head frame body.

[0028] The dispensing head can be swing-adjusted, and the angle of the dispensing head can be adjusted through this mechanism according to the height of the flanging part of the sleeve. Compared with the glue dispensing in the vertical state, the inclined glue dispensing of the dispensing head of this mechanism can slightly increase the glue amount at the relatively higher flanging part on one side of the joint, while slightly reducing the glue amount at the relatively lower unflanged part on the other side of the joint, reducing the glue amount difference on both sides of the joint, realizing a reasonable distribution of the glue amount, and avoiding the tearing and damage caused by too little / too thin glue amount at the relatively higher flanging part on one side of the joint.

[0029] In the embodiment of the present utility model, a laser sensor 4 is arranged beside the dispensing head.

[0030] The laser sensor is used to align with the flanging part of the inner surface turned-out sleeve below and detect the height of the flanging part.

[0031] In the embodiment of the present utility model, the laser sensor is fixedly connected to the sensor frame 5, the sensor frame is hinged to the rubber head frame, and the hinge axis of the sensor frame is parallel to the tooling axis of the cuff.

[0032] The sensor frame is used to mount the laser sensor on the rubber head frame.

[0033] In the embodiment of the present utility model, an arc groove strip 6 with its center of the circle located on the axis of its hinge axis is provided on the sensor frame, an internal thread hole is provided on the surface of the corresponding rubber head frame of the arc groove strip, and a locking screw 7 passing through the arc groove strip is screwed on the internal thread hole.

[0034] By loosening and tightening the locking screw, the position of the laser sensor can be adjusted by swinging along the hinge axis of the sensor frame.

[0035] In the embodiment of the present utility model, the driving assembly includes an adjusting cylinder 8, the end of the cylinder body of the adjusting cylinder is hinged to the cylinder mounting plate 9, and the piston rod of the adjusting cylinder is hinged to the rubber head frame.

[0036] When the piston rod of the adjusting cylinder extends and retracts, it drives the rubber head frame to swing back and forth for adjustment.

[0037] In the embodiment of the present utility model, the cylinder mounting plate is screwed to the mounting frame.

[0038] The cylinder mounting plate and the mounting frame are connected into one body by screwing.

[0039] In the embodiment of the present utility model, a connecting piece 10 for hinging with the piston rod of the adjusting cylinder is screwed on the rubber head frame.

[0040] The rubber head frame is hinged to the piston rod of the adjusting cylinder through the connecting piece.

[0041] In the embodiment of the present utility model, a limiting bent part 11 is fixedly provided on the connecting piece, and swing limiting components are arranged on both sides of the mounting frame in the swinging direction of the limiting bent part.

[0042] A limiting bent part is vertically and fixedly provided on the connecting piece, and the limiting bent part and the swing limiting components cooperate with each other for swing limiting.

[0043] In the embodiment of the present utility model, the swing limiting components each include a transfer plate 12 fixedly connected to the mounting frame, internal thread holes are provided on the transfer plates, adjusting screws 13 are screwed in the internal thread holes, and the axial direction of the adjusting screws is parallel to the tooling axis of the cuff.

[0044] That is, when the rubber head frame body swings and adjusts, the connecting piece swings synchronously, and the limiting crank part on it abuts against the adjusting screw to limit the swing. By rotating the adjusting screw, the position of the adjusting screw can be changed to change the limiting position of the abutting.

[0045] In the embodiment of the present utility model, the tooling includes a shaft body 15 for sleeving the sleeve 14, and the shaft body is driven to rotate by a motor.

[0046] The inner surface of the sleeve faces outward and the outer surface faces inward and is sleeved on the outer peripheral part of the shaft body, exposing its hem part and seam. When dispensing glue, the motor drives the shaft body and the sleeve to rotate, and the glue dispensing head does not rotate.

[0047] In the embodiment of the present utility model, as Figure 1 shown is a schematic structural diagram of the sleeve. In this figure, the inner surface of the sleeve faces outward and the outer surface faces inward. The part A shown in the figure is the area where silicone needs to be applied. The glue dispensing head of the glue dispensing head swing adjustment mechanism of the sleeve can be swing-adjusted, and the angle of the glue dispensing head can be adjusted through this mechanism according to the height of the hem part 16 of the sleeve. Compared with the state of dispensing glue in the vertical state (as Figure 5 shown), the inclined glue dispensing of the glue dispensing head of this mechanism can make the glue amount at the relatively higher hem part on one side of the seam slightly increase, while the glue amount at the relatively lower unhemmed part on the other side of the seam slightly decrease, reducing the glue amount difference on both sides of the seam (as Figure 6 shown), realizing a reasonable distribution of the glue amount, and avoiding tearing and damage caused by too little / too thin glue amount at the relatively higher hem part on one side of the seam.

[0048] In the embodiment of the present utility model, as Figure 5 , 6 shown is a simplified diagram of the working state of glue dispensing. In order to facilitate the indication of the hem part and the glue thickness situation, the dimensions in the figure are enlarged. The height of the hem part and the glue thickness situation of the actual product are overall smaller than the dimensions shown in the figure.

[0049] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
