Problems solved by technology

[0002] Most of the tensioning machines currently on the market do not have the function of automatically reclaiming the webbing. After unloading the goods, the operator has to spend time arranging the webbing; some tensioning machines with the function of rewinding the webbing cannot control the recycling speed when recycling the webbing It cannot be stopped arbitrarily, causing the metal hook at the front end of the webbing to spring back suddenly, and even causing personal injury; some structures are complex and inconvenient to operate

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] 1-4, the automatic take-up and tensioning machine of the present invention mainly includes an organic casing 1, a handle 2, a take-up reel 9, a take-up device 5, a large baffle assembly 3, a small baffle assembly 4, a brake Plate assembly 6 and webbing retainer 10, wherein:

[0028] The casing 1 and the handle 2 are pivotally connected together through a main shaft 7 . The upper edge of the two side walls of the casing 1 is correspondingly provided with a protrusion 11, which divides the front and rear parts of the side wall of the casing into a tensioning operation area 12 for tensioning the webbing and a tensioning operation area 12 for releasing or retracting the webbing. Active release take-up zone 13. When the handle 2 and the large baffle (active ratchet) 31 are in the operating area 12, the webbing can be tightened to tighten t...

Abstract

The invention relates to a tensioning device. Wherein, the framework of tensioning device has a tensioning operation section and a releasing retraction section for tensioning and releasing size ribbon; the back axle of framework has a rotational retraction brake plate and a double twisted spring of brake plate; the front part of handle has a eccentric protrude arc for pushing brake plate and small baffle plate; the main axle has a retraction disc with ratchet wheel at two ends and a retraction device to retract size ribbon via swirl spring; the big baffle plate of handle has a big baffle plate and a double twisted spring that forcing big baffle plate; the big baffle plate has press key and the compress feet for initiating the retraction brake plate. Said invention has the function of general tensioning device that bounding goods and it can automatically retraction size ribbon while it can freely adjust the retraction speed or stop retraction in the process of retracting size ribbon, to avoid metallic hook rebounding. And it has simple operation and high safety.

Description

technical field [0001] The invention relates to a tensioning machine, in particular to a tensioning machine that can be automatically retracted. It is suitable for various automobiles, trailers, motorcycles, airplanes and ships. Time-saving and labor-saving, and the webbing can be automatically recycled, eliminating the trouble of arranging and tightening the webbing after unloading the goods. Background technique [0002] Most of the tensioning machines currently on the market do not have the function of automatically reclaiming the webbing. After unloading the goods, the operator has to spend time arranging the webbing; some tensioning machines with the function of rewinding the webbing cannot control the recycling speed when recycling the webbing Can not be stopped at will, causing the metal hook at the front end of the webbing to rebound suddenly, and even cause personal injury; some have complex structures and are inconvenient to operate. Contents of the invention ...
