Industrial ratchet products. A manual screw tightening tool, single-head, double-head, multi-action ratchet wrench (fixed hole). It is composed of different sizes of main plum blossom sleeves and a plumb sleeve that is connected by a female key and a male key of an articulated key. Because a plum blossom sleeve has two sizes of plum-shaped through holes, it can be used for the tightness of two types of screws, thereby expanding the scope of use, saving raw materials and labor costs. The movable trigger can easily adjust the angle of use of the wrench. This type of wrench is used for the tightening operation of the screw and has the characteristics of strong applicability, convenient use and low cost.
The morphological structure observed by the nylon produced by the melt-spinning method in the microscope has a circular cross-section and no special longitudinal structure. The filamentous fibrillar tissue was observed under an electron microscope. The fibril of nylon 66 was about 10-15 nm in width.
A cam mechanism is generally a high-counter mechanism composed of a cam, a follower, and a frame. The cam is usually rotated at a constant speed, and the follower is designed according to the requirements to make it obtain a certain regular motion. The cam mechanism can realize complex motion requirements and is widely used in various automated and semi-automatic mechanical devices.
A/elastic:Hooked/knotted elastic band/twisted elastic band/weave elastic band/Newton elastic band/pulled elastic band/anti-slip elastic band/jacquard elastic band B/straps: round rubber rope/pin pass, PP, low-elastic, acrylic, cotton, twine, etc. C/knitted tape: Due to its special structure, it refers to the horizontal (dimensional) elasticity, which is mainly used for knitting D/letters: Polypropylene, Letters, Double Letters, Letters, etc. E/figure: transparent shoulder strap, yarn, thread
By designing an appropriate cam profile, the follower can be given any desired movement, and the structure is simple, compact, and easy to design. Therefore, automatic machines, light industrial machinery, textile machinery, printing machinery, food machinery, packaging machinery and Mechatronics products are widely used.
The law of movement of the valve stem defines the outline of the cam. When the sagittal cam profile is in contact with the flat bottom of the valve stem, the valve stem reciprocates; when the arc segment with the center of the cam turning center comes into contact with the valve stem, the valve stem will stay still . Therefore, with the continuous rotation of the cam, the valve stem can obtain intermittent, regular motion.
Polyester terephthalate (PET) is a high molecular compound. Polyethylene terephthalate (PET) is produced by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). Part of the PET is finally produced by underwater pelleting. Fiber-grade polyester chips are used to make polyester staple fibers and polyester filaments.
