It is mainly used for the stop of the pallet on the production line, so it is also called the stop cylinder, due to its fixed working stroke, so there are also companies called the fixed-range rod cylinder. There are medium, heavy; Vertical horizontal type of various specifications1. Selection of buffer capacity 2. Selection of transverse load capacity 3. Selection of cylinder diameter 4. Finally, determine the type and model of the cylinder according to the choice of item 1 and item

The block cylinder can be divided into:  roller lever buffer block cylinder Roller type blocking cylinder Direct blocking type blocking cylinder Horizontal blocking cylinderThe blocking cylinder is a product developed for the automatic conveying system, which can conveniently and reliably control the operation fixture and the transportation and stopping of products.A buffer device can reduce the impact of the fixture plate or its fixture on the block cylinder and prevent the fixture from bouncing.When used, the spring action of the buffer block will produce rolling contact with the bottom of the fixture plate when it passes by.When the jig passes through the roller completely, the roller rises to the highest point to be used as the next jig. Therefore, the production of logistics transmission system can achieve the purpose of free beat. The block cylinder is mainly used in double speed chain and differential speed chain production line.The double speed chain conveyor USES the double speed chain to increase the speed of the chain, so that the pallet (also known as the tool plate) on which the goods are carried can move quickly. The general stop stops at the corresponding operation position, or the operation can be resumed by the corresponding instruction to complete the function of the accumulator release and the movement, transpotion, and turning.When working, it can run continuously or intermittently, and can beat compulsively or freely, which is known as "flexible manufacturing unit" internationally.
