Description

Technical Field

[0001] The invention relates to the technical field of wool fabric processing, in particular to a production and processing device for worsted wool fabric. Background Art

[0002] The drying process is a crucial step in the production and processing of worsted wool fabrics. Its quality and efficiency directly impact the final product quality and the economic benefits of the entire production process. The drying process not only affects the fabric's moisture content, which in turn determines subsequent processing performance and finished product quality, but is also closely linked to key indicators such as production energy consumption and cycle time. However, traditional worsted wool drying methods have gradually exposed numerous insurmountable drawbacks in response to modern market demands and industry development challenges.

[0003] In traditional drying methods, the drying roller is usually stationary or simply rotating, and the relative flow rate between the fabric and the hot air is low. This results in insufficient heat exchange between the hot air and the fabric, and the hot air cannot quickly and effectively transfer heat to the fabric, resulting in slow evaporation of moisture on the fabric surface and a significant reduction in drying speed. In addition, because the drying roller is stationary or rotates in a single manner, the fabric may have close contact with the drying roller in some areas during the drying process, while other parts are in loose contact. This causes excessive heat to be applied to the areas in close contact, which is prone to local overheating, potentially damaging and discoloring the fabric fibers. In addition, the direction and range of hot air flow in traditional drying chambers are relatively fixed, which can easily lead to hot air accumulation or poor flow in local areas. Therefore, it is necessary to develop a new worsted fabric production and processing device to address the problems existing in traditional drying methods. Summary of the Invention

[0004] The object of the present invention is to provide a production and processing device for worsted wool fabrics to solve the problems raised in the above background technology.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: A production and processing device for worsted wool fabrics, comprising a conveying mechanism for conveying the wool fabrics, a drying chamber for providing a space for drying the wool fabrics, and a drying mechanism for drying the wool fabrics, wherein the drying mechanism comprises: The drying roller assembly comprises at least two drying rollers arranged in parallel, with air-permeable micropores evenly distributed on the surface of the drying rollers, and a first connecting rod and a second connecting rod respectively fixedly mounted at both ends of the drying rollers to be rotatably connected to the drying chamber; A driving assembly connected to the second connecting rod, used for driving the drying roller to rotate; The guide assembly is arranged inside the drying chamber and is used to guide the flow direction of the hot air in the drying chamber.

[0006] Optionally, the first connecting rod is a hollow structure, with a ventilation pipe provided inside. One end of the ventilation pipe is rotatably connected to the drying roller, and the other end is connected to the gas pipeline.

[0007] The rotation of the drying roller enables the worsted wool fabric to be in uniform contact with the surface of the drying roller during the drying process, avoiding local overheating or insufficient drying of the fabric, ensuring uniform drying of the fabric as a whole, and improving the drying quality. At the same time, the rotating drying roller increases the relative flow rate between the fabric and the hot air, strengthens the heat exchange process, enables the hot air to transfer heat to the fabric more effectively, speeds up the drying speed, and improves production efficiency.

[0008] Optionally, the drive assembly includes a large gear fixedly mounted on the second connecting rod, the large gears on two adjacent second connecting rods are meshedly connected, a mounting bracket is provided on the drying chamber, a drive motor is provided on the mounting bracket, the output shaft of the drive motor is fixedly connected to a small gear No. 1, and the small gear No. 1 is meshedly connected to one of the large gears.

[0009] The drive assembly transmits power to the drying roller through the meshing connection between the small gear No. 1 and the large gear, so that the drying roller can rotate at the set speed to meet the needs of fabric drying.

[0010] Optionally, the guide assembly includes two parallel horizontal plates arranged along the conveying direction of the worsted wool fabric, and a plurality of connecting shafts are rotatably installed between the two horizontal plates at equal intervals, and guide blades with an arc-shaped structure are fixedly installed on the connecting shafts.

[0011] The rotation of the guide vanes can effectively change the flow direction of the hot air in the drying chamber, so that the hot air can be more evenly distributed in the drying chamber, thereby improving the utilization rate of the hot air and further enhancing the drying effect.

[0012] Optionally, sprockets are fixedly installed at both ends of the connecting shaft, and chains are set outside the sprockets set on the same side. Two pressure wheel groups are set on each horizontal plate, and the pressure wheel groups are set along the length direction of the horizontal plate. Each pressure wheel group includes several pressure wheels.

[0013] The sprocket and chain are provided to ensure the coordination of several coupling shafts and guide vanes, so as to better guide the flow of hot air.

[0014] Optionally, one end of one of the connecting shafts is fixedly connected to an extension shaft, which is arranged close to the large gear and is rotatably connected to the drying chamber. A reciprocating swing component is provided on the extension shaft to enable the extension shaft to swing back and forth.

[0015] Optionally, the reciprocating oscillating assembly includes a sheave, a transmission shaft, a second pinion and a dial, the sheave is fixedly mounted on the extension shaft, the transmission shaft is rotatably mounted on the drying chamber, the second pinion and the dial are coaxially fixedly mounted on the transmission shaft, the second pinion is meshed with one of the large gears, a plurality of radial grooves are provided at equal angles on the sheave, and a round pin that matches the radial grooves is fixedly mounted on the dial.

[0017] During the rotation of the sheave, the counterweight will generate inertial force due to gravity, which helps the sheave to return to its initial position more accurately after the round pin leaves the radial groove, thereby ensuring the reliability of the intermittent rotation of the guide vane.

[0018] The beneficial effects of the present invention are: 1. The drying roller rotates under the action of the driving component. The rotating drying roller increases the relative flow rate between the fabric and the hot air, strengthens the heat exchange process, and enables the hot air to transfer heat to the fabric more effectively, thereby accelerating the drying speed and improving production efficiency. The rotation of the drying roller enables the worsted wool fabric to be evenly in contact with the surface of the drying roller during the drying process, thus avoiding local overheating or insufficient drying of the fabric and ensuring uniform drying of the fabric as a whole. The reciprocating swing of the guide vane can change the flow direction and range of the hot air in the drying chamber, so that the hot air forms a more complex flow pattern in the drying chamber, avoiding the accumulation of hot air in local areas or poor flow, so that the hot air can cover the entire fabric surface more evenly, further improving the drying uniformity. The reciprocating swing of the guide vane can accelerate the flow of air in the drying chamber, enhance the convective heat exchange between the hot air and the fabric, promote the evaporation of moisture on the fabric surface, shorten the drying time and improve the drying efficiency. 2. Using the No. 1 small gear as the active component to drive the large gear to rotate reduces the rotation speed of the large gear, so that the fabric has more sufficient contact time with the surface of the drying roller. Sufficient contact time can make the fabric heated more evenly, avoiding insufficient or excessive local heating of the fabric due to the excessive rotation speed of the drying roller; using the large gear as the active component to drive the No. 2 small gear to rotate speed up the rotation speed of the dial, so that the round pin on the dial enters and leaves the radial groove of the groove wheel more frequently, thereby accelerating the swing frequency of the guide vane, making the hot air more evenly distributed in the drying chamber, avoiding local hot air accumulation or poor flow, and improving the utilization rate of the hot air.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual Figures 1-6 This embodiment discloses a production and processing device for worsted wool fabric, including a conveying mechanism 1, a drying chamber 2 and a drying mechanism 3, wherein the conveying mechanism 1 is used to convey the worsted wool fabric, the drying chamber 2 is used to provide a space for drying the worsted wool fabric, and the drying mechanism 3 realizes the drying of the worsted wool fabric.

[0023] The main function of the conveying mechanism 1 is to smoothly and continuously convey the worsted wool fabric into the drying chamber 2, and transport it out of the drying chamber 2 after drying, so as to realize the position transfer of the fabric in the production process and ensure the continuity of the entire production and processing process. It adopts the crawler conveyor commonly found on the market, including a frame, a conveyor belt, rollers and other structures. Because it belongs to the existing technology, the specific structure of the conveying mechanism 1 will not be described in this application.

[0024] Refer to the instruction manual Figure 1 and Figure 2 The drying chamber 2 is located outside the frame. Shielding curtains 4 are installed at both the entrance and exit of the drying chamber 2. Both curtains 4 are made of PVC material. These curtains 4 can reduce heat loss within the drying chamber 2 to a certain extent, maintaining the temperature environment within the drying chamber 2 while allowing fabrics to enter and exit smoothly, thus isolating the external environment from the drying environment. The conveying mechanism 1 transports the worsted wool fabric into the drying chamber 2 for drying within the drying chamber 2 without pausing during transportation. Once drying is complete, the fabric is transported out of the drying chamber 2.

[0025] Refer to the instruction manual Figure 3-Figure 6 The drying mechanism 3 includes a drying roller assembly 31 , a driving assembly 32 and a guide assembly 33 .

[0026] Among them, the drying roller assembly 31 includes at least two parallel drying rollers 311 arranged in the drying chamber 2, and the drying rollers 311 are arranged along the direction of the rollers of the conveying mechanism 1, and the drying rollers 311 are arranged above the rollers in the conveying mechanism 1. The surface of the drying roller 311 is evenly distributed with breathable micropores 312, and the first connecting rod 313 and the second connecting rod 314 are fixedly installed at both ends of the drying roller 311, and the first connecting rod 313 and the second connecting rod 314 are both rotatably connected to the drying chamber 2, wherein the first connecting rod 313 is a hollow structure, and a ventilation pipe 315 is arranged in the first connecting rod 313, one end of the ventilation pipe 315 is rotatably connected to the drying roller 311, and the other end of the ventilation pipe 315 is connected to the air supply pipe 316, and the air supply pipe 316 is connected to the external hot air blower. The hot air generated by the hot air blower enters the drying roller 311 through the air supply pipe 316 and the ventilation pipe 315, and then overflows from the air permeable micropores 312. The rotation of the drying roller 311 allows the worsted wool fabric to be in uniform contact with the surface of the drying roller 311 during the drying process, thereby avoiding local overheating or insufficient drying of the fabric, ensuring that the fabric as a whole is dried evenly, and improving the drying quality. At the same time, the rotating drying roller 311 increases the relative flow rate between the fabric and the hot air, strengthens the heat exchange process, and enables the hot air to transfer heat to the fabric more effectively, thereby accelerating the drying speed and improving production efficiency.

[0027] The driving assembly 32 includes a large gear 321 fixedly mounted on the second connecting rod 314, and the large gears 321 on two adjacent second connecting rods 314 are meshed and connected. A mounting bracket 322 is provided on the drying chamber 2, and a driving motor 323 is provided on the mounting bracket 322. The output shaft of the driving motor 323 is fixedly connected to a number one small gear 324, and the number one small gear 324 is meshed and connected to one of the large gears 321. In this embodiment, the number one small gear 324 is arranged below the large gear 321.

[0028] The guide assembly 33 includes two parallel horizontal plates 331 fixedly mounted on the top inner wall of the drying chamber 2. The two horizontal plates 331 are arranged along the conveying direction of the worsted wool fabric, that is, the horizontal plates 331 are arranged perpendicular to the drying roller 311. A number of connecting shafts 332 are rotatably mounted at equal intervals between the two horizontal plates 331. The connecting shafts 332 are fixedly mounted with guide vanes 333. The guide vanes 333 are of an arc-shaped structure. The guide vanes 333 change the flow direction of the hot air in the drying chamber 2 by rotation. Sprockets 334 are fixedly mounted on both ends of the connecting shafts 332. That is, the number of sprockets 334 is twice the number of connecting shafts 332. The sprockets 334 arranged on the same side are externally provided with chains 3341. By arranging the sprockets 334 and the chains 3341, it is possible to To achieve the synchronous movement of the multiple coupling shafts 332 and guide vanes 333, each cross plate 331 is provided with two pressure roller groups, which are arranged along the length of the cross plate 331. Each pressure roller group includes multiple pressure rollers 3342, and the number of pressure rollers 3342 in each pressure roller group is equal. Two pressure rollers 3342 are provided between two adjacent sprockets 334 on the same side, and the two pressure rollers 3342 are located in the same vertical plane. The two pressure rollers 3342 respectively contact the upper and lower sides of the chain 3341. The provision of the pressure roller groups limits and guides the chain 3341, ensuring the stability and accuracy of the chain 3341 during transmission, preventing the chain 3341 from derailing or jumping teeth during transmission, and ensuring the synchronous and stable movement of components such as the coupling shaft 332 and guide vanes 333 connected to the chain 3341.

[0029] One end of one of the connecting shafts 332 is fixedly connected to an extension shaft 335, which is arranged close to the side of the large gear 321 and is rotatably connected to the drying chamber 2. A reciprocating swing component is provided on the extension shaft 335, which realizes the reciprocating swing of the extension shaft 335.

[0030] The reciprocating swing assembly includes a groove wheel 336, a transmission shaft 337, a second pinion 338 and a dial 339, wherein the groove wheel 336 and the dial 339 are in the same vertical plane, wherein the groove wheel 336 is fixedly mounted on the extension shaft 335, the transmission shaft 337 is rotatably mounted on the drying chamber 2, and the transmission shaft 337 is arranged between the extension shaft 335 and the large gear 321, the second pinion 338 and the dial 339 are fixedly mounted on the transmission shaft 337, and the second pinion 338 and the dial 339 are coaxially arranged, and the second pinion 338 is meshed with one of the large gears 321, wherein a plurality of radial grooves 3361 are opened at equal angles on the groove wheel 336, and a round pin 3391 is fixedly mounted on the dial 339, and the round pin 3391 is eccentrically arranged, and the round pin 3391 is adapted to the radial groove 3361.

[0031] When the worsted wool fabric production and processing device is in use, the conveying mechanism 1 is used to transport the worsted wool fabric to the drying chamber 2 for drying. At the same time, the external hot air blower is turned on to generate hot air. The hot air flows along the air delivery pipe 316 into the ventilation pipe 315, then enters the drying roller 311, and overflows from the air permeable micropores 312 provided on the drying roller 311, thereby drying the worsted wool fabric in the drying chamber 2. At the same time, the driving motor 323 is turned on, and the output shaft of the driving motor 323 drives the first small gear 324 to rotate. Since the first small gear 324 is meshed with one of the large gears 321, and the two adjacent large gears 321 are meshed with each other, all the large gears 321 rotate synchronously with the first small gear 324, thereby realizing the rotation of all the drying rollers 311. The first small gear 324 is used as the active member to drive the large gear 321 to rotate, which reduces the rotation speed of the large gear 321, so that the fabric has more sufficient contact time with the surface of the drying roller 311. Sufficient contact time can make the fabric heated more evenly, and avoid insufficient or excessive local heating of the fabric due to the excessive rotation speed of the drying roller 311. At the same time, since one of the large gears 321 is meshed with the second small gear 338, the second small gear 338 rotates synchronously with the first small gear 324 and the large gear 321, and the second small gear 338 drives the transmission shaft 337 and the dial 339 to rotate synchronously. During the rotation of the dial 339, the round pin 3391 on the dial 339 is inserted into one of the radial grooves 3361 on the groove wheel 336, and through the cooperation between the round pin 3391 and the radial groove 3361, the groove wheel 336 is driven to rotate a certain angle. In this process, the groove wheel 336 drives the extension shaft 335 and the guide vane 333 to rotate synchronously. Since several connecting shafts 332 are connected by the sprocket 334 and the chain 3341, all the connecting shafts 332 and the guide vane 333 can rotate synchronously at a certain angle. When the round pin 3391 leaves When the radial groove 3361 is opened, under the action of gravity of the guide blade 333, the groove wheel 336 moves to the initial position. As the dial 339 rotates, the round pin 3391 on the dial 339 is inserted into the radial groove 3361 at the same position again, and the above operation is repeated to realize the reciprocating swing of the connecting shaft 332 and the guide blade 333. The reciprocating swing of the guide blade 333 can change the flow direction and range of the hot air in the drying chamber 2, so that the hot air forms a more complex flow pattern in the drying chamber 2, avoiding the accumulation of hot air in local areas or poor flow, so that the hot air can cover the entire fabric surface more evenly, further improving the drying uniformity, and the reciprocating swinging guide blade 333 can accelerate the flow of air in the drying chamber 2, enhance the convective heat exchange between the hot air and the fabric, promote the evaporation of moisture on the fabric surface, shorten the drying time, and improve the drying efficiency. In addition, the large gear 321 is used as the active part to drive the second small gear 338 to rotate, which speeds up the rotation speed of the dial 339, so that the round pin 3391 on the dial 339 enters and leaves the radial groove 3361 of the groove wheel 336 more frequently, thereby accelerating the swing frequency of the guide blade 333, making the hot air more evenly distributed in the drying chamber 2, avoiding local hot air accumulation or poor flow, and improving the utilization rate of the hot air.

[0032] Furthermore, a crossbar 3362 is fixedly mounted on the sheave 336. The crossbar 3362 is eccentrically positioned and perpendicular to the sheave 336. The crossbar 3362 is positioned between two adjacent radial slots 3361 and is equidistant from the radial slots 3361 on either side. A connecting rope 3363 is attached to the crossbar 3362, the end of which is connected to a counterweight 3364. The weight of the counterweight 3364 creates an additional restoring torque. When the connecting shaft 332 and the guide vanes 333 rotate a certain angle, the crossbar 3362, the connecting rope 3363, and the counterweight 3364 also rotate synchronously. When the round pin 3391 leaves the radial slot 3361, the sheave 336 returns to its initial position under the weight of the counterweight 3364 and the guide vanes 333.

[0033] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
