Problems solved by technology

Because there is hard friction between the sawtooth on the upper surface of the feeding lower tooth frame and the lower surface of the feeding upper press frame when idling, and soft friction with the sewing material will occur when the sewing material is put in, the hard friction and soft friction will cause the lower feeding tooth The tooth tip of the sawtooth on t

Example Embodiment

[0015] Such as figure 1 , figure 2 Shown is an embodiment of the grabbing mechanism of the portable packaging machine, including the lower grabbing frame 1, the grabbing upper pressing frame 2, and the machine needle 3. The needle 3 passes through the grabbing upper pressure frame 2 and grabbing from top to bottom. Material lower frame 1, feeding lower frame 2 close and hold up the feeding upper press frame 1 and the sewing material to grasp the sewing material, and then feed the lower frame 2 together with the sewing material from figure 1 The left side of the center slides to the right side relative to the upper feeder 1 for a certain stroke of feeding. The right side of the upper gripper 2 is equipped with a gripper upper presser arm 2a to facilitate the insertion of sewing materials and the upper gripper The lower surface of the press frame 2 is provided with a needle slot 2b. The lower grabbing frame 1 is installed on the feeding mechanism (not shown) located below by the ...

Abstract

The invention relates to a material grabbing mechanism for a portable bag closer, which comprises a material grabbing upper pressure rack and a material grabbing lower retainer, wherein a machine needle passes through the material grabbing upper pressure rack and the material grabbing lower retainer from top to bottom, the upper surface of the material grabbing lower retainer is provided with sawteeth, the material grabbing upper pressure rack and the material grabbing lower retainer can be kept close to each other to feed materials cooperatively, the upper surface of the material grabbing lower retainer is also provided with skid-proof needle points of which the tops are higher than the sawteeth, the lower surface of the material grabbing upper pressure rack is provided with a needle hiding groove, the height of the skid-proof needle points is not greater than the depth of the needle hiding groove, the length of the needle hiding groove is not less than the sum of the diameter of theskid-proof needle points and the forward and backward moving strokes of the skid-proof needle points, and the skid-proof needle points extend into the needle hiding groove when the material grabbing lower retainer is kept close to the material grabbing upper pressure rack. The structure can avoid the hard abrasion generated between the skid-proof needle points and a material feeding upper pressure rack so as to effectively keep the sharpness of the skid-proof needle points and bring the beneficial effect that the material grabbing mechanism grabs materials firmly and feeds the materials reliably.

Description

technical field [0001] The invention relates to a portable bag sealing machine, in particular to a material grabbing mechanism therein. Background technique [0002] Portable bag sealing machine is mainly used for sewing bulk, granular and powder packaging bags, and is widely used in factories, docks, warehouses and other occasions. The portable bag sealing machine is mainly composed of a transmission mechanism, a needle mechanism, a feeding mechanism, a crochet mechanism, a grasping mechanism and other mechanisms that can move cyclically to cooperate with each other. The grasping mechanism of the existing portable bag sealing machine usually includes a feeding upper pressing frame and a feeding lower rack. The upper surface of the feeding lower rack is provided with sawtooth, and the feeding lower rack is driven by the transmission mechanism and the feeding mechanism. until the feeding lower rack supports the sewing material and the feeding upper pressing frame, and becaus...
