Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of belt connection machine field, in particular to a kind of super wide belt longitudinal connection machine. BACKGROUND

[0002] The belt connection machine is a kind of equipment for the hot-pressing connection of two belts, which enables two independent belts to be connected without traces. The Chinese patent CN117087181B discloses a box-type air-cooled connection machine for belt connection, which comprises a chassis and a bottom plate. The top of the bottom plate is fixedly connected with a vertical plate. The end of the fixing component away from the air cylinder is fixedly connected with a top cover. The top of the support plate is fixedly connected with a bearing seat. The top of the bearing seat is fixedly connected with a placement plate. The top of the placement plate is fixedly connected with a bearing block. The bearing block is in contact with the top cover. The outer wall of the bearing block is fixedly connected with an anti-deviation mechanism. The inner wall of the bearing seat is fixedly connected with a suction fan. The middle of the protective shell is fixedly connected with a filter screen. After installing the belt, the device is locked. The locking mechanism is manually fixed in the positioning frame and the fixed frame. The rotating shaft is rotated, so that the rubber head generates a force on the stop block. The stop block is in contact with the inner wall of the positioning frame through the square hole, and a force is generated therebetween, thereby achieving the locking effect.

[0003] The above technical solution does not separate the packaging connection machine during belt connection. The locking mechanism needs to be set at both ends of the connection machine to lock the upper and lower top covers and support seats before pressing connection. However, this connection machine cannot be used to process super-wide belts due to the limitation of the locking mechanism at both ends. The belt needs to be completely placed between the top cover and the support seat and cannot be exposed. Usually, a large-specification connection machine with a length of 3-4 meters is installed to connect such belts. With the expansion of industrial production scale and the emergence of special application scenarios, the width of some belts far exceeds this standard. If the length of the connection machine is simply increased to process these super-specification belts, it will greatly increase the equipment cost and affect the equipment footprint and the single type of products processed by special equipment.
