[0002] The frame of insulating glass needs to be sealed with sealant. The cavity of the insulating glass is sealed with sealant to ensure the thermal insulation and sound insulation performance of the insulating glass. There are two types of sealants for insulating glass according to the characteristics of the insulating glass. One is ordinary insulating glass, which uses hot melt glue for edge sealing, and the other is more advanced insulating glass, which uses adhesive strips for edge sealing.

[0003] For the processing of insulating glass sealed with rubber strips, the conveying process of the rubber strips is relatively complicated, resulting in the existing glue-applying machine head structure being complex and redundant, and the structure being large and heavy, which is not conducive to the application of automated equipment.

DETAILED DESCRIPTION

[0018] 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.

[0019] Embodiment 1:

[0020] like Figure 1As shown, the head structure of a code strip machine described in the utility model includes a mounting frame 1, on which a front limiting mechanism 2, a feeding power mechanism 3, a cutting mechanism 4 and a pressure strip mechanism 5 are sequentially arranged along the conveying direction of the rubber strip. The limiting mechanism 2 is used to limit the upper, lower, left and right feeding positions of the rubber strip to ensure the stable feeding action of the rubber strip. The limiting mechanism 2 includes a plurality of pairs of front limiting columns 21 and a pair of limiting rollers 22. In this embodiment, the limiting rollers 22 are located at the rear side of the front limiting columns 21, and the two limiting rollers 22 are arranged in an up-and-down position. The spacing between the two limiting rollers 22 is slightly smaller than the thickness of the rubber strip, so as to limit the conveying of the rubber strip and maintain the tension of the rubber strip. The two pairs of front limiting columns 21 have two pairs, one pair of which is arranged in a front-to-back position relationship, and the other pair of which is arranged in an up-and-down position relationship, so as to limit the feeding angle of the rubber strip and ensure the stable feeding of the rubber strip.

[0021] The feeding power mechanism 3 includes two pairs of clamping wheels 31 arranged in an upper and lower position. In this embodiment, the top pair of clamping wheels 31 and the bottom pair of clamping wheels 31 are both power wheel sets. One of the clamping wheels 31 in each pair of power wheel sets is driven by a motor, and the power wheel set is a synchronous pulley. A transmission belt 32 is tensioned between the two pairs of power wheel sets. The spacing between the two sets of transmission belts 32 is slightly smaller than the thickness of the rubber strip. Through the reverse rotation drive of the two pairs of transmission belts 32, the rubber strip can be driven to be stably transported downstream through friction.

[0022] A feeding platform 6 is arranged between the end of the feeding power mechanism 3 and the pressure strip mechanism 5. The feeding platform 6 carries and guides the rubber strip to a certain extent to ensure the stable transportation of the rubber strip. The feeding platform 6 has a notch 61 at the cutting mechanism 4. The cutting mechanism 4 is a pneumatic shear. The pneumatic shear corresponds to the notch 61. The scissors of the pneumatic shear can be opened and closed at the notch 61 to complete the shearing of the rubber strip. Specifically, the pneumatic shear is a bevel shear, and the notch 61 is an inclined opening. By shearing the rubber strip at an angle, the two ends of the rubber strip can be butted at an angle, which increases the contact area and ensures good bonding of the rubber strip.

[0023] The beading mechanism 5 includes a slide cylinder 51 and a beading roller 52. The beading roller 52 is rotatably connected to the front end of the piston rod of the slide cylinder 51, and the beading roller 52 is parallel to the mounting frame 1. Through the extension action of the slide cylinder 51, the rubber strip can be stably pressed into the edge gap of the insulating glass through the bottom surface of the beading roller 52, so that the rubber strip can be stably laid.

[0024] Several blocking rollers 7 are arranged outside the rear side of the mounting frame 1. The blocking rollers 7 include mounting plates 71 arranged at both ends and a connecting column 72 in the middle. A contact column 73 is arranged outside the connecting column 72, and the contact column 73 is located in a direction away from the mounting frame 1. The blocking rollers 7 serve as a limiting mechanism for the rubber strip. When the machine head rotates to glue the other sides of the insulating glass, the rubber strip is blocked by the blocking rollers 7 to prevent the rubber strip from sticking to the rest of the structure on the machine head and causing a safety accident. The contact column 73 on the outside rotates with the mounting plate 71, so that the friction between the two can be reduced while limiting the rubber strip, thereby ensuring the stable transportation of the rubber strip.

[0025] A matching plate 62 is arranged on the feeding platform 6 from the notch 61 to the upper part in the downstream direction, and a material guide channel is provided between the matching plate 62 and the feeding platform 6. The matching plate 62 and the feeding platform 6 are matched and limited to stably convey the rubber strip.

[0026] A rotation drive mechanism 8 is arranged at the rear side of the mounting frame 1. The rotation drive mechanism 8 is used to drive the machine head to rotate so that the machine head can lay the adhesive strip on the side of the insulating glass.

[0027] Furthermore, at least one pair of central limiting posts 9 are arranged between the feeding power mechanism 3 and the cutting mechanism 4, and the central limiting posts 9 also play a role in limiting the conveying of the rubber strip. In this embodiment, the central limiting posts 9 are installed downstream of the feeding power mechanism 3 to ensure the position of the rubber strip discharge.

[0028] Furthermore, a protective shell 11 may be installed on the top of the mounting frame 1 to protect the components installed on the mounting frame 1 .

[0029] Embodiment 2:

[0030] like Figure 2 As shown, for Example 1, the positional relationship between the front limit column 21 and the limit roller 22 in this embodiment is different from that in Example 1. In this embodiment, the front limit column 21 is installed on the rear side of the limit roller 22, so as to better limit the entry angle of the rubber strip at the feeding power mechanism 3. In addition, in this embodiment, only the pair of clamping wheels 31 at the bottom are the power wheel group, and the pair of clamping wheels 31 at the top are the non-powered wheels. The non-powered wheels are rubber wheels. The rubber strip can be stably transported by the drive of the synchronous belt pulley group below. The front limit column 21 is closer to the feeding power mechanism 3, which can ensure the accuracy of feeding the rubber strip to the feeding power mechanism 31.

[0031] Since the top clamping wheel 31 in this embodiment is a non-powered wheel, the inner limiting column of the middle limiting column 9 in this embodiment can be set between the two non-powered wheels, so that the rubber strip can be conveyed more accurately through the dispersion of the middle limiting column 9.
