Abstract

The utility model relates to a portable bag closing machine with a conveniently-replaced crochet needle, and mainly solves the problem that a single crochet and a double crochet of a portable bag closing machine in the prior art are not convenient to replace when used on the same machine. The crochet needle (2) comprises the single crochet and a double crochet. The portable bag closing machine is characterized in that the crochet needle (2) is in detachable connection with a crochet needle shaft (4), a crochet needle swinging arm (6) and an auxiliary swinging arm (7) which are matched with a cam mechanism (5) is fixedly arranged on the crochet needle shaft (4), and the cam mechanism (5) and the crochet needle shaft (4) are installed in the same machine shell (8). The crochet needle of the portable bag closing machine can be detached and installed conveniently, and the single crochet needle and the double crochet needle are convenient to replace.

Description

A kind of hand-hold packer of being convenient to the crochet hook replacing

Technical field

The utility model relates to a kind of sewing apparatus of sewing up flexible package and rigid package, is specifically related to a kind of hand-hold packer that crochet hook is changed of being convenient to.

Background technology

Portable bag closer is mainly used in packing the stitching of the packaging bag of bulk, particle and Powdered thing, is widely used in the places such as factory, harbour, warehouse.Portable bag closer is generally the performance single-mode, be monofilar mode or bifilar mode, existing portable bag closer motor, latch needle mechanism, eedle mechanism and feed mechanism, its hook line action mainly is to be finished by latch needle mechanism, and need to change latch needle mechanism when the hook line pattern on the machine changes on the same stage, latch needle mechanism adopts an eccentric cam and an edge cam to control respectively crochet hook and swings and move, latch needle mechanism is divided into single line latch needle mechanism and two-wire latch needle mechanism, need eccentric cam during pattern conversion, edge cam and crochet hook are changed simultaneously, and single line crochet hook and two-wire crochet hook are changed inconvenient when same machine uses.

The utility model content

When using, same machine change inconvenient problem in order to solve existing portable bag closer single line crochet hook and two-wire crochet hook, the utility model provides a kind of hand-hold packer that crochet hook is changed of being convenient to, the crochet hook of this closer can remove and install easily, makes things convenient for single line crochet hook and two-wire crochet hook to replace.

The technical solution of the utility model is: a kind of hand-hold packer of being convenient to the crochet hook replacing, comprise eedle and crochet hook, eedle links to each other with motor by driving mechanism, the motor rotation can make the eedle linear reciprocating motion, crochet hook links to each other with motor by hooked needle shaft and cam mechanism, the motor rotation can make crochet hook cooperate eedle to realize the action of hook line, crochet hook comprises single line crochet hook and two-wire crochet hook, removably connect between crochet hook and the hooked needle shaft, be fixed with the crochet hook swing arm and the secondary swing arm that match with cam mechanism on the hooked needle shaft, described cam mechanism and hooked needle shaft are installed in the same casing.

Described cam mechanism is integrally-built three curved surface cams, and its interlude is provided with the recessed crank slot of a circle, and the both sides of recessed crank slot are provided with the first cam surface of revolution and the second cam surface of revolution, and cam mechanism is installed on the main shaft.

Described hooked needle shaft and main shaft be arranged in parallel, and the swing arm end of crochet hook swing arm and secondary swing arm is respectively near the first cam surface of revolution and the second cam surface of revolution.

The beneficial effects of the utility model are: owing to taking technique scheme, can dismantle easily and install between crochet hook and the hooked needle shaft, be convenient to mutually change between single line crochet hook and the two-wire crochet hook, cam mechanism drives hooked needle shaft makes the single line crochet hook have identical movement locus with the two-wire crochet hook, and the shape of single line crochet hook and two-wire crochet hook is different can to suture single line chain type stitching and double chainstitch.

Description of drawings

Accompanying drawing 1 is structural representation of the present utility model.

Among the figure: the 1-eedle; The 2-crochet hook; The 3-motor; The 4-hooked needle shaft; The 5-cam mechanism; The swing arm of 6-crochet hook; The secondary swing arm of 7-; The 8-casing; The recessed crank slot of 9-; 10-the first cam surface of revolution; 11-the second cam surface of revolution; The 12-main shaft.

The specific embodiment

Below in conjunction with accompanying drawing a kind of closer of the utility model is described further.

As shown in Figure 1, a kind of hand-hold packer of being convenient to the crochet hook replacing, comprise eedle 1 and crochet hook 2, eedle 1 links to each other with motor 3 by driving mechanism, motor 3 rotations can make eedle 1 linear reciprocating motion, crochet hook 2 links to each other with motor 3 by hooked needle shaft 4 and cam mechanism 5, motor 3 rotations can make crochet hook 2 cooperate eedle 1 to realize the action of hook line, crochet hook 2 comprises single line crochet hook and two-wire crochet hook, removably connect between crochet hook 2 and the hooked needle shaft 4, be fixed with the crochet hook swing arm 6 and the secondary swing arm 7 that match with cam mechanism 5 on the hooked needle shaft 4, described cam mechanism 5 and hooked needle shaft 4 are installed in the same casing 8.Owing to taking technique scheme, can dismantle easily and install between crochet hook 2 and the hooked needle shaft 4, be convenient to mutually change between single line crochet hook and the two-wire crochet hook, cam mechanism 5 drives hooked needle shaft 4 makes the single line crochet hook have identical movement locus with the two-wire crochet hook, and the shape of single line crochet hook and two-wire crochet hook is different can to suture single line chain type stitching and double chainstitch.

Described cam mechanism 5 is integrally-built three curved surface cams, and its interlude is provided with the recessed crank slot 9 of a circle, and the both sides of recessed crank slot 9 are provided with the first cam surface of revolution 10 and the second cam surface of revolution 11, and cam mechanism 5 is installed on the main shaft 12.Cam mechanism 5 is compared with original mechanism, simplifies the structure, and parts are less, makes structure compacter.

Described hooked needle shaft 4 be arranged in parallel with main shaft 12, and the swing arm end of crochet hook swing arm 6 and secondary swing arm 7 is respectively near the first cam surface of revolution 10 and the second cam surface of revolution 11.When changing crochet hook 2, cam mechanism 5 need not be dismantled, the position relationship of hooked needle shaft 4 and cam mechanism 5 can be kept all the time, the phenomenon of bouncing pilotage in the time of can not appearing at the hook line.
