Description

Technical Field

[0001] The utility model relates to the field of warp knitting machines, in particular to a needle bed heat dissipation system of a double needle bed Jacquard warp knitting machine. Background Art

[0002] Jacquard warp knitting machine is the main machine for producing decorative fabrics. Its jacquard function is mainly realized by jacquard bars, on which jacquard needle blocks are installed. At present, the market has higher and higher requirements for the jacquard function of machines, which has led to an increasing number of jacquard bars on machines, and wireless electronic jacquard needle blocks have also been the most widely used. Since the wireless electronic jacquard needle block integrates a complex driving circuit, the electronic components will generate a certain amount of heat during the power-on operation. When the heat accumulates, it will affect the structure of the bar bed, causing the bar bed to expand and deform, thereby causing the jacquard yarn guide needle pitch to change, which is not conducive to the normal weaving of the machine. Therefore, the wireless electronic jacquard bar bed uses carbon fiber material to control the change in the yarn guide needle pitch caused by thermal expansion and deformation. However, when the yarn is knitting, the friction with the looping needles and the unlooping sinker bed will also generate heat, causing the needle bed to expand and deform, and the needle pitch of the knitting needles to change. Because the needle bed is made of steel, the needle pitch of the knitting needles does not match the needle pitch of the carbon fiber jacquard comb guide needles, which will cause needle rubbing and needle collision, resulting in the machine being unable to knit normally. Through experiments, it was found that under a room temperature of 28°C, the temperature rise of the steel needle bed reached +4°C after the machine ran for half an hour. At this time, the micrometer measured that the expansion and deformation of the end face of the needle bed had reached 0.15mm, and normal knitting production could not be carried out. Therefore, measures need to be taken to control the temperature of the needle bed when the machine is running to reduce the change in needle pitch. Utility Model Content
