Description

Knotted fishing net machine orifice left and right movement device

technical field

The utility model relates to the technical field of aquatic products, in particular to a left and right movement device for a hole plate of a knotted fishing net machine.

Background technique

The main form of fishery production in my country is net fishing. In recent years, with the rapid development of fishery production, the net gear required every year is also increasing, so timely provision of high-quality fishing nets is also the basis for vigorously developing fishery. In order to weave high-quality fishing nets, during the weaving process of knotted fishing nets, the movement of the orifice plate is the core movement of the whole machine, and the orifice plates move linearly along the X, Y, and Z directions respectively (X, Y, and Z are Front and rear, up and down and left and right directions), the movements in these three directions are carried out by three different mechanisms respectively, which are called orifice plate front and rear, up and down and left and right movement mechanisms, and there are corresponding orifice plate front and rear, up and down and left and right movement devices. The function of the orifice plate is to guide the warp thread in the hole of the orifice plate to form a loop under the joint action of the comb hook, upper hook and lower hook, and the main function of the left and right movement of the orifice plate is to change a shuttle distance left and right when a round of knotting ends, so that The warp thread of the next loop is knotted with one of the weft threads on the edge. This patent mainly studies the left and right movement mechanism of the orifice plate and the corresponding movement device.

The gear 10' is fixedly mounted on the shaft 11', just in time to mesh with the gear 9', and the drive shaft 11' rotates. The rotation of the shaft 11' makes the gear 12' fixedly mounted on it rotate, the gear 13' fixedly mounted on the shaft 15' meshes with the gear 12', and the gear 13' and the cylindrical cam 14' are connected as a whole with screws, Therefore, the cylindrical cam 14' also rotates together, and the roller 16' moves in the groove of the cylindrical cam, so that the swing arm 18 sleeved on the bracket 17 swings, and the other end of the swing arm 18 is connected with the pull rod 19 with a spherical pair, and the pull rod 19 The other end and the orifice plate 20 are also connected with a spherical pair. Therefore, when the cylindrical cam 14' rotates to drive the swing arm 18 to swing, the pull rod 19 drives the orifice plate 20 to move left and right.

This kind of motion device has the following disadvantages: (1) The contour of the cylindrical cam is a complex space surface, which is difficult to accurately analyze and design, and also puts forward high requirements for processing and high cost; (2) Due to the diameter of the roller and the cylinder The width of the cam groove is consistent and it is difficult to ensure good lubrication at the high-pair contact, and it is easy to wear during the movement, so that there is a gap between the roller and the groove, which causes shock, vibration and noise; (3) Multi-stage gears are used Transmission, the mechanical transmission system is long, which reduces the transmission accuracy of the whole machine.
