Description

Technical Field

[0001] The utility model belongs to the technical field of looms, and particularly relates to an energy-saving weft insertion system for an air jet loom. Background Art

[0002] As a key component of the loom, the weft insertion system of the air jet loom mainly uses the high-speed airflow generated when compressed air is released through small holes to pull the weft yarn through the shed to achieve the weft insertion function. The weft insertion system of the air jet loom is mainly composed of the main jet, auxiliary main jet and auxiliary jet device. At present, the main jet, auxiliary main jet, auxiliary jet and solenoid valve of most air jet looms on the market are connected through air pipes. In particular, the wider the reed width and the longer the air path, the disadvantage of transmitting compressed air through air pipes is that the loss of compressed air in the air pipeline cannot be avoided, and there is also a lag in the transmission process. The use of traditional structures will cause serious loss of compressed air and reduce the weft insertion rate.

[0003] The solenoid valve used in the prior art belongs to the traditional solenoid valve structure, which is the model currently used in the conventional configuration of the air jet loom. This type of solenoid valve is large in size and weight, and the installation space is limited, and it is impossible to achieve multi-spray fabrics. At the same time, the main spray device and the auxiliary spray device need to follow the loom beating mechanism to continuously swing at high speed. Since the solenoid valve is heavy and is fixed on the valve seat by screw holes, the continuous high-frequency swing is bound to have a great impact on the service life of the solenoid valve.

[0004] In addition, in the prior art, ordinary quick-connect connectors are used as the constant air jet pipe connectors in the main spray device and the auxiliary main spray device. This type of connector has two major disadvantages: ① The main spray device swings rapidly with the loom, and the use of quick-connect connectors will cause the air pipe connection to be loose and the air pipe is very easy to detach; ② Because the air pressure of the constant air jet pipeline is much lower than the air pressure of the main air circuit connected to the solenoid valve, when the solenoid valve is opened to intake air, part of the air pressure will rush into the constant air jet path, causing air pressure loss, resulting in unstable air pressure, and greatly reducing the purpose of energy saving.

[0005] Therefore, how to overcome the above technical defects is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0053] The core of the utility model is to provide an energy-saving weft insertion system for an air jet loom, which can effectively reduce air pressure loss and improve air pressure stability.

[0054] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] Specifically, please refer to Figure 1-Figure 12 The utility model provides an energy-saving weft insertion system for an air jet loom, comprising: a main jet and solenoid valve integrated device 100, and / or an auxiliary main jet and solenoid valve integrated device 500, and / or an auxiliary jet and solenoid valve integrated device 200.

[0056] Among them, Figure 3-Figure 7 As shown, the main spray and solenoid valve integrated device 100 includes a main spray valve seat 110, a main spray air intake pipe joint 120, a main spray normal spray air intake pipe joint 130, a main spray solenoid valve 140, a main spray core 150 and a main spray nozzle 160.

One end of the main jet nozzle core 150 and the main jet nozzle 160 are simultaneously installed in the main jet core channel 115, and the other end of the main jet nozzle 160 is exposed.

[0057] like Figure 10-11As shown, the auxiliary main spray and solenoid valve integrated device 500 includes an auxiliary main spray valve seat 510, an auxiliary main spray normal spray air intake pipe joint 520, an auxiliary main spray core 530, an auxiliary main spray solenoid valve 540, an auxiliary main spray air intake pipe joint 550 and an auxiliary main spray nozzle 560. The auxiliary main spray valve seat 510 is provided with an auxiliary main spray solenoid valve installation cavity 511 for installing the auxiliary main spray solenoid valve 540, an auxiliary main spray core channel 512 for installing the auxiliary main spray core 530, and an auxiliary main spray core channel 513 for installing the auxiliary main spray core 530. The auxiliary main jet normal jet inlet pipe joint installation hole 513 of the auxiliary main jet normal jet inlet pipe joint 520, the auxiliary main jet inlet pipe joint installation hole 514 for installing the auxiliary main jet inlet pipe joint 550, and the auxiliary main jet cavity channel 516, the auxiliary main jet solenoid valve installation cavity 511 and the auxiliary main jet core channel 512 are connected through the auxiliary main jet cavity channel 516, the auxiliary main jet core channel 512 passes through the auxiliary main jet valve seat 510, and the auxiliary main jet core 530 is connected to the auxiliary main jet nozzle 560. One end of the auxiliary main jet core 530 and the auxiliary main jet nozzle 560 are simultaneously installed in the auxiliary main jet core channel 512, and the other end of the auxiliary main jet nozzle 560 is exposed.

[0058] like Figure 8-Figure 9 As shown, the integrated auxiliary spray and solenoid valve device 200 includes an auxiliary spray solenoid valve seat 210, an auxiliary spray solenoid valve 220, an auxiliary spray air inlet pipe joint 230, an auxiliary spray air outlet pipe joint 240 and an auxiliary nozzle 250. The interior of the auxiliary spray solenoid valve seat 210 is respectively provided with an auxiliary spray solenoid valve installation cavity 211 for installing the auxiliary spray solenoid valve 220, an air inlet channel 212 for installing the auxiliary spray air inlet pipe joint 230 and an air outlet channel 213 for installing the auxiliary spray air outlet pipe joint 240. The end of the auxiliary spray air outlet pipe joint 240 away from the air outlet channel 213 is connected to the auxiliary nozzle 250.

[0059] The main spray nozzle 160, the auxiliary main spray nozzle 560 and the auxiliary nozzle 250 all utilize the high-speed airflow generated when the compressed air is released through the small hole to pull the weft yarn through the shed to complete the weft insertion process.

[0060] like Fig.12 As shown, both the main jet core 150 and the auxiliary main jet core 530 can use an annular coaxial nozzle, one end of the nozzle is provided with a first inlet for connecting to the air cavity channel and a second inlet for connecting to the installation hole of the normal jet air inlet pipe joint, the other end of the nozzle is connected to the nozzle and forms a central hole located in the center and an annular hole located outside the central hole, the central hole can be connected to the second inlet, and the annular hole is connected to the first inlet, so that the gas can be ejected in a high-speed stream.

[0061] The main jet air intake pipe joint 130 and / or the auxiliary main jet air intake pipe joint 520 both adopt a special one-way flow embedded structure. One-way flow means that the main jet air intake pipe joint 130 and / or the auxiliary main jet air intake pipe joint 520 in this solution can only take in air in one direction and cannot discharge air in the opposite direction.

[0062] It should be noted that in the prior art, since the air pressure of the normal air jet circuit is much lower than the air pressure of the main air circuit connected to the solenoid valve, when the solenoid valve is opened to intake air, part of the air pressure will rush into the normal air jet circuit, causing air pressure loss, leading to unstable air pressure, and greatly reducing the energy-saving effect. The use of a one-way flow embedded structure can completely solve this problem. The one-way flow embedded structure provided in this case is a two-in-one structure of a one-way valve and an embedded joint. There is no such configuration in the current energy-saving weft insertion system of the air jet loom. It is a key design of the utility model, which can improve airflow efficiency and reduce pressure imbalance, thereby improving the performance and reliability of the entire system.

[0063] The energy-saving weft insertion system of the jet loom provided by the utility model is improved by improving at least one of the main jet and solenoid valve integrated device 100, the auxiliary main jet and solenoid valve integrated device 500 and the auxiliary jet and solenoid valve integrated device 200, and by designing an air path inside the valve seat, compared with the air pipe connection method used in the prior art, the air path channel is made more compact and the air path is closer, which can effectively reduce the pipeline gas residue, improve the response time of the jet component, and speed up the air pressure establishment time of the jet component. At the same time, each joint, solenoid valve and jet core are installed on the mounting position on the valve seat through an embedded structure, so that the installation is firm and the sealing is good. The main jet normal jet air inlet pipe joint 130 and / or the auxiliary main jet normal jet air inlet pipe joint 520 both adopt a special one-way flow embedded structure, which can meet the circulation mode that the gas can only be inhaled in one direction and cannot be discharged in the opposite direction, effectively reduce the air pressure loss, stabilize the air pressure, and improve the energy saving effect.

[0064] In a specific embodiment, the main spray solenoid valve installation cavity 112 includes a first solenoid valve air inlet cavity 117 and a first solenoid valve air outlet cavity 118 , and the main spray cavity channel 113 is used to connect the first solenoid valve air outlet cavity 118 and the main spray core channel 115 .

[0065] The auxiliary main spray solenoid valve installation cavity 511 includes a second solenoid valve air inlet cavity and a second solenoid valve air outlet cavity, and the auxiliary main spray cavity channel 516 is used to connect the second solenoid valve air outlet cavity and the auxiliary main spray core channel 512 .

[0066] The main spray solenoid valve installation chamber 112 is provided with two-stage chambers, namely, the first solenoid valve air inlet chamber 117 and the second solenoid valve air outlet chamber 118. Specifically, the main spray chamber passage 113 connects the first solenoid valve air outlet chamber 118 with the main spray core passage 115. The main spray solenoid valve installation chamber 112 is provided with two-stage chambers, which has the advantages of reducing the risk of the entire system stopping working due to a single point failure, ensuring that the main spray solenoid valve 140 operates more accurately and reliably, and improving the stability and working efficiency of the system.

[0067] The auxiliary main spray solenoid valve installation chamber 511 includes a second solenoid valve air inlet chamber and a second solenoid valve air outlet chamber, and the auxiliary main spray chamber passage 516 is used to connect the second solenoid valve air outlet chamber and the auxiliary main spray core 530 passage. The auxiliary spray solenoid valve installation chamber 211 includes a third solenoid valve air inlet chamber and a third solenoid valve air outlet chamber, the air inlet passage 212 is connected to the third solenoid valve air inlet chamber, and the third solenoid valve air outlet chamber is connected to the air outlet passage 213. Of course, the beneficial effect of the above-mentioned main spray solenoid valve installation chamber 112 being provided with a two-stage chamber is also applicable to the auxiliary main spray solenoid valve installation chamber 511 and the auxiliary spray solenoid valve installation chamber 211, which will not be elaborated here.

[0068] In a specific embodiment, one end of the main jet air intake pipe joint 120 is embedded in the main jet air intake pipe joint mounting hole 116, and the other end of the main jet air intake pipe joint 120 is used to lock with the air pipe through a nut. One end of the main jet normal jet air intake pipe joint 130 is embedded in the main jet normal jet air intake pipe joint mounting hole 114, and the other end of the main jet normal jet air intake pipe joint 130 is used to lock with the air pipe through a nut.

[0069] One end of the auxiliary main jet air intake pipe joint 520 is embedded in the auxiliary main jet air intake pipe joint installation hole 513, and the other end of the auxiliary main jet air intake pipe joint 520 is used to lock with the air pipe through a nut. One end of the auxiliary main jet air intake pipe joint 550 is embedded in the auxiliary main jet air intake pipe joint installation hole 514, and the other end of the auxiliary main jet air intake pipe joint 550 is used to lock with the air pipe through a nut.

[0070] One end of the auxiliary jet inlet pipe joint 230 is embedded in the air inlet channel 212, and the other end of the auxiliary jet inlet pipe joint 230 is used to lock with the air pipe through a nut. One end of the auxiliary jet outlet pipe joint 240 is embedded in the air outlet channel 213, and the other end of the auxiliary jet outlet pipe joint 240 is connected to the auxiliary nozzle 250. All of the above joints adopt a special embedded structure, and the air pipe is locked by a nut, which can effectively prevent the air pipe from being disengaged and can better adapt to the scene of high-frequency swing.

[0071] In order to make the installation of the solenoid valve more secure, the main spray solenoid valve 140 is embedded in the main spray solenoid valve installation cavity 112. The auxiliary main spray solenoid valve 540 is embedded in the auxiliary main spray solenoid valve installation cavity 511. The auxiliary spray solenoid valve 220 is embedded in the auxiliary spray solenoid valve installation cavity 211. The embedded installation technology makes the solenoid valve installation more secure, and can also effectively reduce the vibration of the solenoid valve, so as to better adapt to the main spray and solenoid valve integrated device 100 and the auxiliary main spray and solenoid valve integrated device 500 with the high-frequency swing of the sley during work.

[0072] In a specific embodiment, at least one of the main spray solenoid valve 140, the auxiliary main spray solenoid valve 540 and the auxiliary spray solenoid valve 220 can adopt a cylindrical micro solenoid valve, which is cylindrical and has the characteristics of small size, light weight and adaptability to high-frequency operation. At the same time, with a valve body structure matching the cylindrical micro solenoid valve, the entire weft insertion system can also be small in size and light in weight, which can meet the use of multi-spray fabrics, overcoming the problem that the solenoid valve model used in the prior art is large in size and weight, and cannot meet the application of multi-spray fabrics in actual application scenarios due to limited installation space.

[0073] Of course, the appearance of the above-mentioned solenoid valve includes but is not limited to the appearance of a cylinder. It can also adopt a block or other shape, and the installation method and air path of the solenoid valve can be adaptively adjusted. Any adaptive improvement is within the scope of protection of this case and is not further limited here.

[0074] In a specific embodiment, in order to improve the injection efficiency, the main spray core 150, the main spray nozzle 160, the main spray air intake pipe joint 120 and the main spray solenoid valve 140 are multiple in one-to-one correspondence. Correspondingly, the number of the mounting cavities / mounting holes / channels of each component corresponding to each component on the main spray valve seat 110 also corresponds one-to-one. That is, the number of the main spray core 150, the main spray nozzle 160, the main spray air intake pipe joint 120 and the main spray solenoid valve 140 is two, and the number of the main spray solenoid valve mounting cavity 112, the main spray core channel 115, the main spray air intake pipe joint mounting hole 114, the main spray cavity channel 113 and the main spray air intake pipe joint mounting hole 116 on the main spray valve seat 110 is also two. It should be noted that the number of the main spray core 150, the main spray nozzle 160, the main spray air intake pipe joint 120 and the main spray solenoid valve 140 can be one or more, and the specific adaptive selection is made according to the actual application situation, and no further limitation is made here.

[0075] The number of the auxiliary main spray and solenoid valve integrated device 500 and the number of the auxiliary spray and solenoid valve integrated device 200 can be set to one or more.

[0076] In a specific embodiment, the auxiliary main spray and solenoid valve integrated device 500 is connected in series with the main spray and solenoid valve integrated device 100. Such a configuration can reduce the length of the pipeline, thereby reducing the waste of compressed air, and improving the yarn insertion rate, thereby improving the working efficiency of the loom. Specifically, the air bag pressure regulating valve can directly supply air to each solenoid valve, thereby driving the corresponding nozzle / nozzle, which can avoid the waste of compressed air and the problem of injection lag caused by the air pipe connection.
