Problems solved by technology

When producing woven bags, it is necessary to transport the uncut woven fabric to the cutting machine for cutting so that the woven fabric can be cut into a suitable length according to the size of the woven bag, and the woven fabric needs to be clamped by grippers during transportation To facilitate transportation, the existing grippers for grabbing woven fabrics are usually hinged by two handles. The ends of the two handles for gripping are provided with clamping blocks. When the two handles are closed, the clamping blocks will tighten the woven fabric. Clamping, this kind of clamping hand needs to be manually operated, and the number of woven fabrics that can be clamped in one clamping operation is limited, so that the efficiency of clamping is low, resulting in low efficiency of transportation, and poor stability during clamping It is easy to cause the woven cloth to fall off during the clamping process

Embodiment Construction

[0020] Specific embodiments of the present invention such as Figure 1-3 As shown, a mechanical gripper includes a mounting shell 1 and a driving cylinder 2, a rotating arm 3 is hinged on the outer wall of the mounting shell 1, and a first clamping block 4 is arranged on the rotating arm 3, The installation shell 1 is provided with a second clamping block 5, and a clamping port 6 for clamping a woven bag is formed between the first clamping block 4 and the second clamping block 5, and the driving cylinder 2 The output end is provided with a telescopic rod 7, and the rotating arm 3 is connected to the telescopic rod 7 through a transmission mechanism 8. The beneficial effect of such setting: adopt the above-mentioned scheme, before clamping, firstly fold an appropriate amount of woven cloth and lay it flat on the second clamping block 5, then start the driving cylinder 2 so that the telescopic rod 7 protrudes from the cylinder, Thereby the transmission mechanism 8 drives the r...

Abstract

The invention provides a mechanical gripper. The mechanical gripper comprise a mounting shell and a driving air cylinder, a rotating arm is hinged to an outer side wall of the mounting shell, a firstclamping block is arranged on the rotating arm, a second clamping block is arranged on the mounting shell, a clamping opening for clamping woven bags is formed between the first clamping block and thesecond clamping block, a telescopic rod is arranged at the output end of the driving air cylinder, and the rotating arm is in transmission connection with the telescopic rod through a transmission mechanism. The clamping efficiency of the mechanical gripper is high, the clamping stability is strong, and the operation is simple.

Description

technical field [0001] The invention relates to a mechanical gripper. Background technique [0002] Woven bag, also known as snakeskin bag, is a kind of plastic bag used for packaging. Its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. When producing woven bags, it is necessary to transport the uncut woven fabric to the cutting machine for cutting so that the woven fabric can be cut into a suitable length according to the size of the woven bag, and the woven fabric needs to be clamped by grippers during the transportation process. To facilitate transportation, the existing grippers for grabbing woven fabrics are usually hinged by two handles. The ends of the two handles for gripping are provided with clamping blocks. When the two handles are closed, the clamping blocks will tighten the woven fabric. Clamping, this kind of clamping hand needs to be manually operated, and the number of woven fabrics that can be clamped i...
