Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, and in particular to a water-jet loom with a safety and energy-saving drying device. Background Art

[0002] A water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and the diffusion is small. It is suitable for the weft insertion needs of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity during weaving. However, the fabric woven by the water jet loom contains a large amount of water. If it is directly wound into a roll, the cloth will mold, so the cloth needs to be dehydrated. Therefore, the moisture needs to be removed before winding.

[0003] The drying device of the existing water jet loom generally uses steam heated by a boiler to heat the drying roller to dry the cloth. However, steam drying slows down the drying speed of the cloth, resulting in insufficient drying of the finished product, causing the cloth to mold and affecting the shipping quality of the cloth. Therefore, the utility model provides a safe drying device for a water jet loom. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a water jet loom with a safe and energy-saving drying device, the water jet loom comprises a water jet loom unit and a drying box unit.

[0005] The drying box unit includes a drying box body and a hot air blower. The hot air blower is located outside the drying box body. The drying box body includes a plurality of first support guide rollers, a power guide roller, a cloth storage guide roller and a hot air pipe. The drying box body is provided with a cloth inlet channel.

[0006] A plurality of air outlet holes are provided on one side of the hot air pipe, the air outlet holes are rectangular and staggered, one end of the hot air pipe is connected to the hot air blower through a pipeline, the hot air pipe is placed between the two first support guide rollers and the air outlet holes face the grey cloth to be dried;

[0007] During use, the fabric processed by the water-jet weaving unit enters the drying box through the fabric entry channel, and is supported by the first supporting guide roller inside the drying box. The grey fabric is dried by the hot air pipe during the fabric feeding process, and the dried grey fabric is wound onto the fabric storage guide roller through the power guide roller.

[0008] Optionally, the drying box further comprises a circulation fan, an air outlet, and a first air inlet. The drying box is provided with the first air inlet and the air outlet, the air outlet being connected to the second air inlet of the hot air blower via a duct, the circulation fan being disposed between the first air inlet and the air outlet, and the air outlet being disposed above the drying box. Furthermore, the circulation fan is located outside the drying box. By providing the circulation fan, the air outlet, and the first air inlet, when in use, the circulation fan can recycle excess hot air within the box back to the second air inlet of the hot air blower. The hot air blower only requires lower power to produce hot air with the same amount of thermal energy, thereby reducing the power of the hot air blower and achieving energy conservation.

[0009] Optionally, a fan protection cover may be provided on both the hot air blower and the circulating air blower, and the fan protection cover may further protect the hot air blower and the circulating air blower, thereby increasing their service life.

[0010] Optionally, a supplementary air port is provided on the pipe connecting the air outlet and the second air inlet. Furthermore, an air volume detector can be provided at the second air inlet to detect the air volume. If the air volume is insufficient, the supplementary air port can be opened to ensure that the air volume is sufficient to dry the grey cloth at any time.

[0011] Optionally, the hot air pipe is rectangular, with the air outlet holes being 90-110 mm long and 0.5-2 mm wide; the length of the hot air pipe is greater than the width of the grey fabric to be dried. Furthermore, the rectangular shape of the air outlet holes can minimize the mutual influence of gas flow, reduce the generation of wind vortices, and reduce temperature field fluctuations. The staggered arrangement of the air outlet holes and the length of the hot air pipe being greater than the width of the grey fabric can fully dry the grey fabric, improve drying efficiency, and prevent the occurrence of inadequate drying.

[0012] Optionally, the hot air pipe may be cylindrical or rectangular. Preferably, the hot air pipe is rectangular. Preferably, the air outlet is 100 mm long and 1 mm wide.

[0013] Optionally, the water jet loom unit includes a plurality of second support guide rollers and a weaving warp beam, the weaving warp beam being connected to a power motor and positioned at the front end of the second support guide rollers. During the weaving process, the power motor is connected to the weaving warp beam via a belt. Driven by the power motor, the weaving yarn is first warped over the weaving warp beam. The woven fabric then enters the second support guide rollers and is guided by the plurality of second support guide rollers.

[0014] Optionally, the second support rollers include a second support roller A, a second support roller B, a second support roller C, and a second support roller D. The second support rollers A and B are arranged at the same height and spaced apart. The second support roller C is located between the second support roller A and the second support roller B, and its height is higher than that of the second support roller A. The second support roller D is located below the second support roller B. This arrangement can better ensure cloth feeding and smoothness during cloth feeding. For example, the second support rollers may be cylindrical, with the second support rollers A, B, and C being rubber-coated rollers, and the second support roller D being a stainless steel cloth guide roller. The second support rollers can rotate during cloth feeding. For example, to facilitate cloth feeding, the second support roller A may be a powered roller connected to a power motor via a belt, and the second support rollers B, C, and D may be auxiliary guide rollers. However, the present invention is not limited thereto, and those skilled in the art may set the guide roller to be a power guide roller or an auxiliary guide roller according to the application scenario.

[0015] Optionally, the first support rollers include a first support roller A, a first support roller B, and a first support roller C. The first support rollers A and B are located at the same height as the second support roller D and are made of the same material to facilitate cloth guiding. The first support roller C is located above the first support roller B. The powered roller and the first support roller C are located at the same height and spaced apart. The powered rollers are connected to a reduction motor power unit to drive the powered rollers for rotation. The cloth storage roller is located between the powered rollers and the first support roller C and above the powered rollers. The first support rollers A and B are stainless steel cloth guide rollers, while the first support roller C and the powered roller are rubber-covered rollers. The first support roller C supports and guides the cloth. During cloth feeding, the first support rollers are able to rotate. Driven by the reduction motor, the powered rollers rotate. Because the powered rollers are in contact with the cloth storage roller and are rubber-covered rollers, they drive the cloth storage rollers to rotate, thereby winding the dried grey cloth onto the cloth storage rollers. However, the material, shape, size and installation position of the second support guide roller and the first support guide roller in the present invention are not limited thereto, and those skilled in the art can adjust them according to the shape of the loom and the use environment.

[0016] Furthermore, during use, those skilled in the art can adjust the rotational speeds of the power motor and reduction motor based on the size of the weaving warp beam gear and guide roller gear to ensure normal cloth feeding. For example, a touch screen is also included, connected to the power motor and reduction motor, and the speed parameters of the power motor and reduction motor are set through the touch screen.

[0017] Optionally, the water jet loom unit includes an L-shaped fixed weaving temple support. During the drying process of the grey fabric, one end of the L-shaped fixed weaving temple support is detachably connected to the support (for example, fixed to the support by screws), and the fixed position of the L-shaped fixed weaving temple support can be adjusted according to the width of the grey fabric.

[0018] Optionally, the water jet loom unit includes a hot cutting edge. Further, the hot cutting edge is fixed to the bracket by screws, and the hot cutting edge is used to remove the burrs on both sides of the cloth during the cloth running process.

[0019] Optionally, the hot cutting edge includes a fixed iron plate, an electrically insulating plate, a copper busbar, and a heating wire, wherein the electrically insulating plate is connected to the fixed iron plate, and the copper busbar includes a first portion, a second portion, and a third portion. The first portion is fixed to the electrically insulating plate, one end of the second portion and one end of the third portion are respectively connected to the first portion at a certain interval, the other end of the second portion is connected to one end of the heating wire, and the other end of the third portion is connected to the other end of the heating wire. During use of this hot cutting edge structure, the fixed iron plate can be fixed to the bracket by screws, and the power cord is connected to the copper busbar, resulting in a large contact area that is not easily damaged. On the other hand, the copper busbar is used to create a hollow shape in the middle, which facilitates the replacement of the heating wire at a later time.
