Background

The electronic jacquard can weave fabrics with complex organization structures by matching with a rapier loom, an air jet loom and a water jet loom, has good advantages of improving the grade of the fabrics and the added value of products, and has wide application in the textile industry. Since technical information on electronic jacquard machines can be found in published patent documents, typically "crank rocker type electronic jacquard machine" as recommended by CN105400249B, the applicant is not repeated. The aforementioned solenoid valve assembly, also called "solenoid assembly", is an actuator (also called "actuator") that is critical in an automated weaving system because it is capable of converting an electrical signal that characterizes a fabric pattern into a lifting movement of a corresponding warp yarn of the loom when it is operated.

The technical requirements for the aforesaid solenoid valve assemblies are very stringent, for example, the reliability during service, i.e. during use, needs to be ensured, the implications of reliability such as resistance, inductance, electromagnetic attraction, etc. reflecting the actual performance of the electronic jacquard machine. Technical information on the aforementioned solenoid valve assembly of the electronic jacquard is not known in the published chinese patent documents, such as CN101718019A (jacquard solenoid assembly), CN105821553A (jacquard solenoid assembly), CN101845698B (a kind of wire electronic jacquard solenoid assembly), CN102634900A (electronic jacquard solenoid assembly), and CN105155076A (electronic jacquard solenoid assembly), among others.

From a reading of the patent literature, not limited to the above exemplified solenoid valve assemblies, and in combination with general knowledge: the needle number of the jacquard is adapted to the number of the electromagnetic valve components, specifically, the jacquard with twenty thousand needles is provided with twenty thousand electromagnetic valves correspondingly, under the working state, the electromagnetic valves have large self heating value, the temperature of the electromagnetic valve components reaches more than 70 ℃, the high temperature can cause the parameters of the electromagnetic valve components to be unstable, and has great influence on the service life of the internal motion of the electromagnetic valve components, and finally, the fabric quality and the weaving efficiency of the fabric can not be ensured because the electric signals of the fabric pattern are converted into the reliability of the lifting motion of the fabric to the warp. Based on the foregoing, how to ensure good heat dissipation of the electromagnetic assembly is not only a factor of concern for jacquard machine manufacturers, but also an ineffectiveness technical issue that jacquard machine manufacturers must consider.

Although the published chinese patent documents refer to technical information about cooling an electronic jacquard, such as CN202116789U (an induced draft electronic jacquard), CN203411700U (a centralized air blower for a jacquard), and CN206120074A (a cooling device for a jacquard head), the above patent documents are directed to cooling a head and do not relate to cooling a solenoid valve assembly by air.

However, since the left and right bulkheads 7a and 7b are half-sectional plates, the half-sectional plate means: the distance of the height degree of the upper air duct 8a is reserved between the upper parts of the left partition plate 7a and the right partition plate 7b and the housing, and because two rows of electromagnetic valves 7c adjacent to each other in front and back are closely arranged without gaps, and the electromagnetic valves 7c on the same row are also arranged next to each other, in the actual use process, the heat dissipation air duct only has the left air duct 8b and the right air duct 8c, the heat dissipated by the electromagnetic valves 7c can only enter the upper air duct 8a on the upper part and then be discharged through the left air duct 8b and the right air duct 8c, so the core temperature inside the electromagnetic valves 7c is still high, the expected air cooling effect cannot be obtained, and the unstable parameter factors of the electromagnetic valves 7c are not enough to be eliminated. In view of the foregoing, there is a need for improvement, and the technical solutions described below are made in this context.

The cross-sectional shapes of the front support 1 and the rear support 2 are U-shaped, which has the advantage of excellent strength, and facilitates the installation of the related components, such as the fan 9, the front dust-proof mechanism 10, and the rear dust-proof mechanism 20.

As shown in fig. 1, a left knife chamber 30 is formed between the left wall plate 3 and the left partition plate 7a, and a right knife chamber 40 is formed between the right wall plate 4 and the right partition plate 7 b.

When the electronic jacquard machine works, the electromagnetic valve 7c is in a working state, and heat generated by hundreds of thousands of electromagnetic valves 7c is exhausted from the lower part of the module box 7e to the outside under the work of the fan 9, so that the applicant takes the fan 9 and the front dustproof mechanism 10 arranged on the front support frame 1 as an example, under the work of the fan 9, outside air enters the electromagnetic valve gap 7d of each front and back adjacent two rows of electromagnetic valves 7c through meshes on the front dustproof net 102, a front dustproof net frame cavity 1011, a fan air inlet of the fan 9, a fan air outlet of the fan 9 and an upper air duct 8a (namely an upper air cavity) in sequence, so as to take away heat generated by the electromagnetic valves 7c, namely, the heat generated by the electromagnetic valves 7c is exhausted from the lower part of the module box 7e, and thus, the excellent air cooling effect on the electromagnetic valves 7c can be embodied. The reason why the fan 9 provided in the rear carrier 2 operates to cool the solenoid valve 7c by wind is the same as that described above, and therefore, the description thereof will not be repeated. The air flow direction during the air cooling is revealed by the arrows schematically shown in fig. 2.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
