Problems solved by technology

Its shortcomings: because there is no pre-compression device, the compression speed cannot be increased. If the compression speed is forcibly increased, it will inevitably cause the gas in the packaging bag to burst without time to discharge; second, it cannot achieve continuous and uninterrupted packaging, and the efficiency is low. High-speed sanitary products production line is matched and the packaging cost is high

Embodiment 1

[0011] Embodiment 1: refer to Figure 1~3 . Pants-type product packaging machine, which includes a frame 17, a sealing and trimming device 12, and a waste recycling device 15. The moving pre-compression device is a shrinking channel 1, and two sets of mutually symmetrical ring chain transmissions are arranged on both sides of the shrinking channel 1. The mechanism 2 is driven by the pre-compression servo motor 2-3, and the distance between multiple push rods 2-1 is horizontally distributed between the two ring chains 2-2 in the two sets of ring chain transmission mechanisms 2, and the multiple push rods 2-1 are two The ends are respectively connected with two ring links 2-2 and rotate synchronously with the ring chain 2-2; the product compression device 3 is located at the exit of the contraction channel 1 and drives the double-headed screw through the compression servo motor 4, and the double-headed screw at both ends The direction of the screw thread is opposite and rotates...

Embodiment 2

[0012] Embodiment 2: On the basis of embodiment 1, the packaging method of the trousers type product packaging machine includes a PLC controller, and the stacker 18 pushes out the product to be packaged, enters the movable pre-compression device 1, and undergoes pre-compression After exhaust, the pre-compressed trousers products are pushed into the product compression device 3 by multiple push rods distributed in the endless chain transmission mechanism on both sides of the movable pre-compression device 1, and the product compression device 3 is driven by the drive motor 4. The two compression plates that drive the double-headed lead screw move quickly relative to each other to compress the trousers product twice. At the same time as the bag mouth is sucked open, the double door located at the exit of the product compression device 3 opens the double door forward and stretches both sides of the packaging bag under the command of the PLC controller to form a trousers-shaped pro...

Abstract

The invention relates to a pants-type product packing machine capable of packaging and sealing a plurality of pants-type products after precompression gas exhaust and rapid compression, and a packing method. The packing machine comprises a stander, a sealing cutting device and a waste material recovery device, wherein a movable precompression device is in shape of a contraction passage of which two sides are provided with two sets of mutually symmetrical annular chain driving mechanisms driven by a precompression servomotor; a product compressor is positioned at an outlet of the contraction passage 1, and the precompression servomotor drives a double-ended guide screw which drives two compression plates thereon to perform quick relative motions so as to compress the pants-type products; product bag-opening devices are positioned at the outlet of the product compressor and packaging bags are conveyed to the outlet of the compressor through a movable cylinder, and the product bag-opening devices at two sides of the outlet of the contraction passage suck the bag openings of the packaging bags open; a bag conveyor is positioned at the outlet of the product bag-opening device and is driven to move by a bag conveying servomotor; and the sealing cutting device is positioned at the outlet of the bag conveyor.

Description

technical field [0001] The invention relates to a trouser-type product packaging machine and a packaging method capable of precompressing and exhausting a plurality of trouser-type products, quickly compressing them, and automatically packing and sealing them, belonging to the field of packaging machine manufacturing. Background technique [0002] CN2404807Y, title "a kind of packing machine for sanitary napkins", is composed of a bag making part, a bag opening part, a sheet arranging chain part, a bag opening turntable part, a back sealing part and a back conveying part, etc. The plate is composed of a four-sectioned bag sheet, blowing pipe, linear cylinder, gear rod, ratchet mechanism and sheave mechanism. The edge trimming device composed of cylinder, upper and lower cutters, etc. and the gusset forming device composed of rodless cylinder, suction push rod, suction push head, lower pressure plate, limit plate, etc. Its shortcomings: because there is no pre-compression de...
