Description

Technical Field

[0001] This utility model relates to the field of weaving equipment technology, and in particular to a denim fabric weaving device. Background Technology

[0002] Denim is a relatively thick, yarn-dyed warp-faced twill cotton fabric. Denim is characterized by its abrasion resistance, durability, and comfort. The basic structure of denim is formed by interlacing dyed warp yarns and undyed weft yarns on a weaving device.

[0003] The denim fabric produced by the denim weaving device is wound around the take-up shaft. The take-up shaft needs to be replaced regularly. The thick denim fabric makes the take-up shaft quite heavy after winding the fabric, which increases the labor burden of personnel handling and replacing it. In addition, the take-up shaft is located on the lower side of the device, and its upper part is covered by the device's rotating shaft and other components, which restricts the replacement space and further reduces the replacement efficiency. The confined space also makes it easier for bumps and knocks to occur. Summary of the Invention

[0004] This utility model provides a denim fabric weaving device. The take-up shaft moves to the outside of the main weaving machine body along with the lower moving slide, making the replacement space more open and the replacement of the take-up shaft more convenient. This significantly improves the replacement efficiency of the take-up shaft and avoids the space restriction caused by the take-up shaft being located on the lower side of the main weaving machine body, thus avoiding bumps and damage due to insufficient space.

[0005] This utility model provides a denim fabric weaving device, specifically including a main weaving machine body, a lower moving slide, and a front guide bracket. The lower moving slide is slidably connected to the lower part of the main weaving machine body in the horizontal direction. The front guide bracket is rotatably connected to the middle part of the lower moving slide. Side fixing cones are slidably connected to both sides of the lower moving slide in the horizontal direction. The side fixing cones are rotatably connected to the upper part of the side connecting frame. The lower end of the side connecting frame is fixedly connected to the telescopic rod of the telescopic cylinder. Side fixing pins are slidably passed through both sides of the lower moving slide in the vertical direction. A side drive motor is fixed to the side of the side connecting frame on one side of the lower moving slide. The side fixing cone is clamped and fixed to both ends of the take-up shaft.

[0006] Furthermore, the telescopic cylinder is fixedly installed on both sides of the lower moving slide, the side fixing pin is slidably connected to the lower insertion hole of the main weaving machine body, the main shaft of the side drive motor and the side fixing cone are connected by gear meshing, the lower moving slide moves to the outside of the main weaving machine body, and the take-up shaft moves to the outside of the main weaving machine body along with the lower moving slide.

[0007] Furthermore, the lower moving carriage is rotatably equipped with inner rotating shafts on both sides of its rear portion, and the inner rotating shafts are tightly engaged with both sides of the circulating feed belt.

[0008] Furthermore, a front connecting frame is rotatably connected to the rear side of the front guide bracket, and a central fixing pin slides through the middle of the front connecting frame.

[0009] Furthermore, the front guide bracket is located below the take-up shaft, and the front side of the front guide bracket is located below the circulating feed belt.

[0010] Furthermore, a take-up shaft is placed on the upper part of the circulating feed belt, and the front guide bracket is located in the middle position of the side fixed cones on both sides of the lower moving slide.

[0011] Furthermore, when the middle fixed pin and the lower movable slide are slid in, the front guide bracket is in a horizontal state; when the middle fixed pin and the lower movable slide are separated, the front guide bracket is in a downward tilted state.

[0012] This utility model provides a denim fabric weaving device, which has the following beneficial effects:

[0013] When the take-up shaft needs to be replaced, it moves to the outside of the main weaving machine body along with the lower moving carriage, making the replacement of the take-up shaft more convenient and significantly improving the replacement efficiency. This avoids the space limitation caused by the take-up shaft being located on the lower side of the main weaving machine body, and avoids damage caused by insufficient space. The outward movement design of the lower moving carriage makes the replacement space more open, significantly reducing the difficulty of operation and maintenance time costs.

[0014] The take-up shaft moves along the horizontal front guide bracket to guide or align the side fixing cone for installation, eliminating the burden of personnel carrying and lifting the take-up shaft to align the side fixing cone, reducing the labor intensity of personnel during replacement, and effectively avoiding the risk of take-up shaft deviation or falling due to manual handling. The circulating feed belt prepares and transports the take-up shaft in advance, shortening the take-up shaft replacement time and significantly improving the continuous operation capability and production efficiency of the weaving equipment.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model discloses a denim fabric weaving device, comprising: a main weaving machine body 1, a lower moving slide 2, and a front guide bracket 3. The lower moving slide 2 is horizontally slidably connected to the lower part of the main weaving machine body 1. Side fixing cones 201 are horizontally slidably connected to both sides of the lower moving slide 2. The upper parts of the side fixing cones 201 and side connecting frames 202 are rotatably connected. The lower end of the side connecting frames 202 is fixedly connected to the telescopic rod of a telescopic cylinder 203. Side fixing pins 204 slide vertically through both sides of the lower moving slide 2. A side drive motor 205 is fixed to the side of the side connecting frame 202 on one side of the lower moving slide 2. The side fixing cones 201 are clamped and fixed to the two ends of the take-up shaft 208. Both sides of the rear are rotatably equipped with inner rotating shafts 207, which are tightly engaged with both sides of the circulating feed belt 206. The middle of the lower moving slide 2 is rotatably connected to the front guide bracket 3, and the rear side of the front guide bracket 3 is rotatably connected to the front connecting bracket 301. The middle fixed pin 302 slides through the middle of the front connecting bracket 301. The front guide bracket 3 is located below the take-up shaft 208, and the front side of the front guide bracket 3 is located below the circulating feed belt 206. The circulating feed belt 206 transports the upper take-up shaft 208 to the front guide bracket 3. The upper groove of the circulating feed belt 206 is used to place multiple take-up shafts 208. The front guide bracket 3 is located in the middle position of the side fixed cones 201 on both sides of the lower moving slide 2.

[0031] In this embodiment, the telescopic cylinder 203 is fixedly installed on both sides of the lower moving slide 2. The side fixing pin 204 is slidably connected to the lower insertion hole of the main weaving machine body 1. The main shaft of the side drive motor 205 and the side fixing cone 201 are connected by gear meshing. When the lower moving slide 2 moves to the outside of the main weaving machine body 1, the take-up shaft 208 moves to the outside of the main weaving machine body 1 along with the lower moving slide 2. The upper part of the take-up shaft 208 is no longer blocked by the main weaving machine body 1, making the replacement of the take-up shaft 208 more convenient and improving the replacement efficiency of the take-up shaft 208.

[0032] In this embodiment, when the middle fixed pin 302 and the lower movable slide 2 are slid in, the front guide bracket 3 is in a horizontal state. The take-up shaft 208 can also be aligned with the side fixed cone 201 along the horizontal front guide bracket 3, which eliminates the burden of personnel carrying and lifting the take-up shaft 208 to align with the side fixed cone 201 and reduces the labor intensity of personnel during replacement. When the middle fixed pin 302 and the lower movable slide 2 are separated, the front guide bracket 3 is in a front-down tilted state, and the take-up shaft 208 can move downward along the tilted take-up shaft 208.

[0033] In Example 2, based on Example 1, the front connecting frame 301 is replaced by a telescopic cylinder 203 on the front side of the front guide bracket 3. The front guide bracket 3 is provided with a positioning groove for the take-up shaft 208 at the position aligned with the side fixing cone 201. The motor drives the inner rotating shaft 207 to rotate, so that the take-up shaft 208 on the circulating feed belt 206 rolls down to the front groove of the front guide bracket 3 in a horizontal state, realizing the alignment and clamping of the take-up shaft 208 and the side fixing cone 201, eliminating the need for manual alignment and replacement of the side fixing cone 201.

[0034] The working principle of this embodiment: The main weaving machine 1 performs denim weaving operations. The finished fabric of the main weaving machine 1 is wrapped around the take-up shaft 208. The side drive motor 205 engages and drives the side fixed cone 201 and the take-up shaft 208 to rotate synchronously, realizing the synchronous winding of the fabric after production. After the take-up shaft 208 is fully wound, it is disassembled for replacement with a new take-up shaft 208. When it is necessary to replace the take-up shaft 208, the side fixed pin 204 separates from the main weaving machine 1, the lower moving slide 2 moves to the outside of the main weaving machine 1, and the take-up shaft 208 moves to the outside of the main weaving machine 1 along with the lower moving slide 2. The upper part of the take-up shaft 208 is no longer obstructed by the main weaving machine 1. The replacement of the take-up shaft 208 is more convenient, significantly improving the replacement efficiency of the take-up shaft 208. It avoids the space limitation caused by the take-up shaft 208 being located on the lower side of the main weaving machine body 1, avoids the collision damage caused by insufficient space, and avoids the situation where the low position of the take-up shaft 208 increases the difficulty of replacement. In traditional weaving equipment, the take-up shaft 208 is located in a narrow space under the machine body, and the operator needs to bend over or use auxiliary tools to complete the replacement. However, this device, through the outward design of the lower moving slide 2, makes the replacement space more open, significantly reducing the difficulty of operation and maintenance time costs, avoiding the blind spot caused by the main weaving machine body 1 blocking the operation, and effectively reducing the risk of damage to equipment parts.

[0035] The telescopic cylinder 203 shortens, causing the side connecting frame 202 and the side fixing cone 201 to move away from the take-up shaft 208. The fixing of the side fixing cone 201 and the take-up shaft 208 is released, allowing the take-up shaft 208 to move downwards along its inclined state. The take-up shaft 208 then collects and transports the fabric for subsequent inspection. The take-up shaft 208 can also move along the horizontal front guide bracket 3 to guide or align the side fixing cone 201 for installation, eliminating the need for manual handling and lifting. The take-up shaft 208 is aligned with the side fixing cone 201, reducing the burden on personnel during replacement and effectively avoiding the risk of the take-up shaft 208 shifting or falling due to manual handling. The circulating feed belt 206 prepares unused take-up shafts 208 in advance. The rotation of the circulating feed belt 206 transports the take-up shaft 208 to the top of the side connecting frame 202. The pre-prepared take-up shafts 208 shorten the replacement time of the take-up shafts 208 and significantly improve the continuous operation capability and production efficiency of the weaving equipment.
