Description

Technical Field

[0001] The utility model mainly relates to the field of rubber strip conveying, in particular to a machine head rubber strip synchronous movement control mechanism. Background Art

[0002] After the insulating glass is assembled, it is necessary to apply sealant to the side of the insulating glass for sealing. The sealing strip is wound around the rubber disc to form a material disc. As the rubber disc rotates, the strip is gradually released and adhered to the outside of the insulating glass through the machine head. During the conveying process of the strip, the strip often slips between the strip and the conveying wheel, making it impossible to accurately convey the strip, so that the amount of glue cannot be accurately controlled, resulting in poor adhesion of the strip on the side of the insulating glass, affecting the quality of the insulating glass. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a head rubber strip synchronous movement control mechanism, which can accurately control the glue output of the rubber strip and ensure the adhesion effect of the rubber strip on the periphery of the insulating glass.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A synchronous movement control mechanism for a head rubber strip comprises a mounting frame, on which two pairs of synchronous pulleys are arranged in an upper and lower position relationship, synchronous belts are tensioned between the top pair of synchronous pulleys and between the bottom pair of synchronous pulleys, the distance between the top synchronous belt and the bottom synchronous belt is less than the thickness of the rubber strip, and each of the two pairs of synchronous pulleys has a driving wheel, which is driven by a servo motor and gear transmission.

[0006] The upper and lower synchronous pulleys on the same side serve as driving pulleys, and the two synchronous pulleys are coaxially mounted with driving gears. The servo motor drives the two driving gears simultaneously through an output gear.

[0007] A pair of vertical long axis holes are arranged on the top of the mounting frame, and long axis grooves are symmetrically arranged on both sides of the long axis holes, and the long axis grooves are used to fix the shaft seat by bolts.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model can increase the contact area between the rubber strip and the synchronous belt by setting the double-sided synchronous belt, thereby improving the friction force, so that the rubber strip can be accurately conveyed.

[0010] The distance between the two synchronous belts of this device is adjustable, so it can adapt to the conveying of rubber strips of different thicknesses. At the same time, through the adjustable structure of the top synchronous belt, it can also be fine-tuned when there is a problem with the conveying of the rubber strip, ensuring the smooth operation of the equipment.

[0016] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0017] like Figure 1-4 As shown, the utility model discloses a head rubber strip synchronous movement control mechanism, including a mounting frame 1, and the mounting frame 1 serves as the mounting position of the rubber strip degumming mechanism. Two pairs of synchronous pulleys 2 are arranged on the mounting frame 1 in an upper and lower position relationship, and the two synchronous pulleys 2 at the top are arranged in parallel, and the two synchronous pulleys 2 at the bottom are arranged in parallel. A synchronous belt 3 is tensioned between the top pair of synchronous pulleys and the bottom pair of synchronous pulleys, and the distance between the top synchronous belt 3 and the bottom synchronous belt 3 is less than the thickness of the rubber strip. The synchronous belt 3 itself has a certain elasticity, and the rubber strip also has elasticity, so that the two synchronous belts 3 can be used to extrude and convey the rubber strip. The two synchronous belts 3 are in extrusion contact with the rubber strip, which increases the contact area between the two, makes the friction force greater, and can ensure the precise conveying of the rubber strip.

[0018] Each pair of synchronous pulleys 2 has a driving wheel, which is driven by a servo motor 4 and a gear transmission. The upper and lower synchronous pulleys 2 on the same side serve as driving wheels, and the two synchronous pulleys 2 are coaxially mounted with a driving gear 7. The servo motor 4 drives the two driving gears 7 simultaneously through an output gear. The servo motor 4 can ensure a balanced rotation speed, and the two driving gears 7 have the same number of teeth, thereby ensuring that the two synchronous belts 3 are rotated stably at a uniform speed.

[0019] A pair of vertical long-axis holes 5 are arranged at the top of the mounting frame 1, and long-axis grooves 6 are symmetrically arranged on both sides of the long-axis holes 5, and the long-axis grooves 6 are used to fix the shaft seat by bolts. The long-axis hole 5 serves as the shaft through-hole of the synchronous pulley 2, and the inner diameter of the long-axis groove 6 is larger than the outer diameter, so that the outer side of the long-axis groove 6 has a limiting edge, and the top of the long-axis groove 6 has a notch for the insertion of the hexagonal bolt, and the limiting edge on the outer side of the long-axis groove 6 is used to limit the bolt head of the hexagonal bolt. Through this structure, the adjustment of the installation position of the shaft seat can be completed, thereby adjusting the position of the synchronous belt 3 at the top, and then adjusting the spacing between the two synchronous belts 3, to ensure the effect of conveying rubber strips of different thicknesses.

[0020] By setting up this structure, the two synchronous belts 3 can ensure stable contact with the rubber strips, avoid friction between the rubber strips and the synchronous belts 3, and further ensure the accuracy of rubber strip feeding.
