The invention provides an efficient food liquid bag demounting-mounting structure and assembling and demounting-mounting methods and belongs to the field of
food transport devices. According to the efficient food liquid bag demounting-mounting structure and the assembling and demounting-mounting methods, the problem that an existing
liquid food transport vehicle is inconvenient to demount and
mount is solved. The efficient food liquid bag demounting-mounting structure comprises a
carriage, a feeding and discharging cylinder, a liquid bag and a lining cylinder and further comprises an outer connecting sleeve, an inner connecting sleeve, a connecting plate, a sealing cover, an inner sleeve cylinder, an outer sleeve cylinder, lock beads, compression springs, rod holes, pull rods and pull rings. The outer connecting sleeve, the inner connecting sleeve and the connecting plate are connected. The sealing cover comprises a cover ring and a cover plate. The inner sleeve cylinder and the outersleeve cylinder are fixed to the two sides of the lining cylinder. A sleeve groove is formed in the outer wall of the top end of the outer sleeve cylinder, and a lock groove is formed in the inner wall of the inner connecting sleeve; bead grooves are formed in the groove wall of the sleeve groove; the lock beads are embedded in the bead grooves, sliding grooves are formed in the groove walls of the bead grooves, and sliding blocks are arranged on the outer walls of the lock beads. The compression springs are located on the sliding grooves; rod grooves are formed in the outer walls of the lockbeads, and limiting grooves are formed in the groove walls of the two sides of the rod grooves; and the pull rods are arranged in the rod holes in a penetrating mode; and limiting blocks are fixed tothe bottom ends of the pull rods, and the pull rings are connected with the top ends of the pull rods. The efficient food liquid bag demounting-mounting structure has high demounting-mounting efficiency.
