The invention discloses an idler wheel for conveying glass substrates. The idler wheel comprises a wheel main body and a peripheral member, wherein the wheel main body is provided with a convex curved surface and a groove is formed on the surface of the wheel main body and on the outermost edge, and the peripheral member is mutually embedded with the groove on the wheel main body to contact with, support and convey the glass substrates. The idler wheel provided by the invention has the advantages that the glass substrates are prevented from being scraped when being conveyed by the idler wheel; and when the idler wheel needs maintenance and repair, only the peripheral member needs to be changed instead of the whole idler wheel. Therefore, the cost is saved because the idler wheel can be repeatedly used.

The invention relates to a metal pipe bending device with a protection function. The metal pipe bending device comprises a base, a fixing plate, a drive mechanism, a forming mechanism, a clamping mechanism and a control mechanism. According to the metal pipe bending device with the protection function, the drive assembly drives the forming mechanism to achieve bending forming of a pipe, the driveassembly drives two clamping blocks to be close to and away from each other, the workpiece is clamped and loosened, the device stops operating through the control mechanism, and operators are protected; compared with an existing bending device, according to the device, through linkage of the forming mechanism and the clamping mechanism, the pipe is more conveniently mounted and taken down; compared with an existing clamping mechanism, flexible clamping is adopted in the mechanism, and the situation that the workpiece is scratched by rigid clamping is avoided; and compared with an existing button control mechanism, a complex opening manner is adopted in the control mechanism, mis-touch is avoided, and the operators are better protected.

The invention provides a workpiece feeding, arranging and direction arranging device and technology for sorting to-be-tidied workpieces. According to the workpiece feeding, arranging and direction arranging device, based on a plurality of stations lowered layer by layer, the gravity action of the to-be-tidied workpieces is utilized, and the multiple stations are sequentially used for conducting corresponding arranging and direction arranging operation. By adoption of the provided workpiece feeding, arranging and direction arranging device and technology, threats to operator safety during existing manual arranging can be avoided, and the problems that a vibration disc is adopted for repeated vibration and friction, product surface scratches are caused, and the quality is not good can be solved. According to the provided workpiece feeding, arranging and direction arranging device and technology, the gravity action of the to-be-tidied workpieces is utilized, the correspondingly-matched stations are matched, accordingly, the arranging and direction arranging operation on the to-be-tidied workpieces is achieved, and the cost of an integral arranging and direction arranging structure canbe lower.

The invention belongs to the technical field of animal husbandry, particularly relates to a cub feeding device for industrial breeding in the animal husbandry, and aims to solve the problem that an existing cub feeding device is prone to cause food snatching in a feeding process. According to the scheme, the cub feeding device comprises a saddle; two supporting frames are fixedly mounted at the top of the saddle; a milk tank and a residual liquid tank are fixedly mounted at the top ends of the two supporting frames correspondingly; a sealing cover is mounted at the top end of the milk tank through a hasp lock and a hinge; and a driving motor is fixedly mounted at the top end of the sealing cover. When cubs are fed, feeding troughs are pushed out into a breeding fence through electric pushrods installed on the side surfaces, so that the cubs can be attached into the feeding trough for eating; the feeding troughs are separated through separation plates, so that the cubs are prevented from snatching for food, and the feeding quality is improved; and meanwhile, the flexible feeding troughs and the separation plates can prevent skin scratches of the cubs during eating and moving, so that the protection effect on the cubs is improved.
