Surrounding strip press-fit feeding machine

Abstract

The invention provides a surrounding strip press-fit feeding machine. The surrounding strip press-fit feeding machine comprises a rack, and the rack is provided with an unreeling device, a gluing device, a drying device and a press-fit device. The press-fit device comprises a tensioning assembly and an attaching assembly which are sequentially arranged. The attaching assembly comprises a supporting plate, a movable base, a supporting spring, a supporting shaft, a carrier roller, a guide rod, a needle-shaped air cylinder, a limiting wheel, a swinging rod, a pressing rod, a reset spring and an elevating air cylinder. The reset spring and the elevating air cylinder are located at the positions corresponding to the two ends of the swinging rod correspondingly. One end of the reset spring abutsagainst the movable base, and the other end of the reset spring abuts against the swinging rod. The side, towards the tensioning assembly, of the carrier roller is provided with a shearing mechanism.The supporting spring is utilized for compensating for the contraction amount existing in the scanning track, in the surrounding strip attaching process, the changes of extrusion force exerted on thesurrounding strip are relatively weak, the surrounding strip is not prone to deformation, the attaching error is small, the production efficiency is relatively high, and the attaching quality is relatively good.

Description

technical field [0001] The invention relates to a production equipment for vulcanized shoes, in particular to a strip pressing and feeding machine. Background technique [0002] Vulcanized shoes are a kind of shoes formed by using rubber, fabric or leather as the upper surface, using rubber as the bottom material to be processed by pasting, molding or injection, and then vulcanized under a certain temperature and pressure. The sole of vulcanized shoes There is usually an apron attached between the upper and the upper, which is used to strengthen the strength of the shoe and make the appearance more beautiful. [0003] Existing vulcanized shoes usually use manual bonding to complete the process of attaching the perimeter strips, and the perimeter strips need to be cut and glued between the fittings, because the waste generated by cutting may not adhere to the cut strips. On the fence, it needs to be cleaned before use to apply glue, and the production efficiency is relativel...

Problems solved by technology

[0003] Existing vulcanized shoes usually use manual bonding to complete the process of attaching the perimeter strips, and the perimeter strips need to be cut and glued between the fittings, because the waste generated by cutting may not adhere to the cut strips. On the fence, it needs to be cleaned before use to apply glue, and the production efficiency is relatively low

[0004] There are also some enterprises that use equipment such as manipulators to realize the automatic attachment of the fences. Although the production efficiency can be improved, the quality of the attachment is relatively low. Attachment track, the attachment track is also the shape of the enclosure attached to the vulcanized shoe, the shape is as figure 1 As shown, it is a closed-loop and irregular shape formed by the connection of multiple curves. The radius of curvature at the position corresponding to the toe and heel is relatively small, while the radius of the crank at the position corresponding to the waist is relatively large. Therefore, if Directly use the scanning device to rotate around the vulcanized shoe and obtain the attachment track for the handover position between the upper and the sole, then the attachment track will be due to the distance between two adjacent phase acquisition points of the industrial camera of the scanning device There is a difference between the actual attachment trajectory and the actual attachment trajectory. Specifically, the attachment trajectory acquired by the scanning device will shrink inwards relative to the actual attachment trajectory at the position corresponding to the toe and heel. In addition, the scanning device will In the process of forming the attachment trajectory through fitting processing, in order to ensure the smoothness of the trajectory, it is inevitable to perform interpolation filtering, and the above-mentioned shrinkage phenomenon may also occur. The existence of the shrinkage phenomenon makes the manipulator use the attachment trajectory obtained by the scanning device to stick During the process of attaching the surrounding strip, the extrusion force on the surrounding strip changes relatively greatly, which makes the surrounding strip deformed, and the error of the surrounding strip is relatively large, which affects the quality of the attachment
