Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a precision drying device for yarn packages. Background Technology

[0002] Textile equipment, also known as textile machinery, refers to the machines and devices used in textile production to complete various textile processes. It is widely used in the textile, apparel, and home textile industries. In conventional textile production processes, after dyeing and washing, the moisture content of yarn packages increases significantly, necessitating drying. Ordinary drying equipment may suffer from uneven drying and inaccurate temperature control, resulting in inconsistent drying levels between the inner and outer layers of the yarn package, affecting subsequent textile processing and finished product quality. Precision yarn drying devices, however, can precisely control the temperature, flow rate, and circulation path of hot air, ensuring uniform heating of all parts of the yarn package, achieving rapid and even drying, and guaranteeing that the moisture regain of the yarn meets standard requirements to satisfy the needs of subsequent textile production.

[0003] A search revealed Chinese Patent Publication No. CN217585158U, which discloses a yarn drying device, including a drying chamber and a drying rack. The drying rack includes a drying base and multiple main drying pipes mounted on the drying base. Each main drying pipe has multiple sets of branch drying pipes installed on it. Each set of branch drying pipes includes multiple branch drying pipes for inserting and connecting the yarn package to the main drying pipe, and each main drying pipe has multiple ventilation holes. The drying chamber is equipped with a hot air inlet pipe connected to an external hot air blower. The drying rack is equipped with a hot air transfer pipe, one end of which is connected to the main drying pipe, and the other end is connected to the hot air inlet pipe. This application utilizes an external hot air blower to deliver hot air to the yarn package through the hot air inlet pipe, the hot air transfer pipe, and the ventilation holes, enabling precise drying of the yarn package from within, thus improving the drying efficiency and effect.

[0004] The aforementioned patent mentions the beneficial effects as follows: "Workers first place the yarn package support on the drying branch pipe, and then connect the hot air transfer pipe to the main drying pipe, so that the external hot air fan can deliver hot air to the yarn package through the hot air inlet pipe, hot air transfer pipe, and ventilation holes, so as to accurately dry the yarn package from the inside, thereby improving the drying efficiency and drying effect." Although the above solution can improve the drying efficiency and drying effect of the yarn package, there is a significant resource waste problem in the feeding mechanism of some existing yarn package drying equipment. When manually placing the yarn package, due to the lack of precise positioning and layout planning, it is difficult for workers to ensure that the yarn package is tightly and evenly distributed on the drying surface. On the bearing surface of drying equipment, voids easily form at the edges and corners, making it difficult to fully utilize the space resources of the drying equipment, limiting the drying capacity per cycle, and increasing the energy cost per unit product. While existing automatic feeding equipment has a certain degree of automation, during material changeover, due to limitations in mechanical structure and the lack of an effective detection and feedback mechanism, the connection between the new material and the existing yarn package is not tight enough, also creating voids. The existing feeding method cannot effectively utilize the space resources of the drying equipment, resulting in a mismatch between function and resource utilization, which restricts the efficiency and effectiveness of drying production. Therefore, a precision yarn package drying device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a precision drying device for packaged yarn, which aims to improve the problem in the prior art that it is difficult to ensure that the packaged yarn is tightly and evenly distributed on the bearing surface of the drying equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A precision drying device for packaged yarn includes a base, with multiple fixed supports fixedly connected to the top left side of the base, fixed plates fixedly connected to the top of two of the fixed supports, a drive assembly one installed on the top of the fixed plates, a fixed seat fixedly connected to the top of the base, a feeding assembly installed on the top right side of the fixed seat, a fixed box fixedly connected to the top right side of the base, a drive assembly two installed on the front side of the fixed box, and a drying oven fixedly connected to the top of the fixed box.

[0008] The drive assembly includes an electric push rod, the bottom of which is fixedly connected to the top of one of the fixed plates.

A pipe is fixedly connected inside the movable column. An air pump is fixedly connected to the rear side of the pipe. Multiple grippers are fixedly connected to the bottom of the movable column.

[0009] The above technical solution involves an electric push rod driving a moving column to move along a slide rail to achieve position adjustment, and an air pump providing power to the gripper through a pipeline, enabling the gripper to accurately grasp and release the yarn package, thus transferring the yarn package from its initial position to the transfer station and ensuring the stability and accuracy of the yarn package during the transfer process.

[0010] As a further description of the above technical solution:

[0011] The feeding assembly includes a motor, the bottom of which is fixedly connected to the top of the fixed base. A rotating rod is fixedly connected to the drive end of the motor. A sprocket is fixedly connected to the outside of the rotating rod. A chain is sleeved on the outside of the sprocket. A fixed frame is fixedly connected to the top right side of the fixed base.

A sprocket is fixedly connected to the outside of the rotating rod. A connecting block is fixedly connected to the outside of the chain. A positioning grid is fixedly connected to the left side of the connecting block. Multiple fixed rods are fixedly connected to the top of the fixed base. Multiple miniature optical grating sensors are fixedly connected to the top of the positioning grid.

[0012] Through the above technical solution: Motor 1 drives the positioning grid to move up and down through sprocket and chain transmission to feed the yarn package. The micro grating sensor detects the placement status of the yarn package in real time to ensure the accuracy and integrity of the feeding. At the same time, it provides precise position information for the subsequent gripping of the drive component 1, thereby improving the feeding efficiency and automation level.

[0013] As a further description of the above technical solution:

[0014] The second drive assembly includes a load-bearing plate, a second motor is fixedly connected to the top of the load-bearing plate, a first rotating shaft is fixedly connected to the drive end of the second motor, a conveyor belt is sleeved on the outside of the first rotating shaft, and a second rotating shaft is rotatably connected to the inside of the left side of the fixed box.

[0015] Through the above technical solution: motor two drives rotating shaft one, which in turn drives rotating shaft two to make the conveyor belt run. The load-bearing plate provides stable support for motor two, so as to realize the conveying of the yarn package transferred from driving component one to the drying oven, ensuring the smoothness and continuity of the yarn package transmission process. It is an important transmission link for the yarn package from the grabbing station to the drying station.

[0016] As a further description of the above technical solution:

[0017] The left side of the conveyor belt is fitted inside the outside of the second rotating shaft, and the outside of the first rotating shaft is rotatably connected to the right side of the fixed box.

[0018] The above technical solution ensures that the conveyor belt can operate stably, preventing the yarn from shifting or jamming during transmission due to an unstable transmission structure, and ensuring that the yarn is smoothly and accurately transported into the drying oven for drying.

[0019] As a further description of the above technical solution:

[0020] The external parts of the plurality of fixing rods are slidably connected to the inside of the positioning grille, and the right side of the positioning grille is slidably connected to the right side of the fixing frame;

[0021] The above technical solution ensures that the positioning grid can only move along a fixed trajectory during its up-and-down movement, avoiding swaying or deviation. This guarantees the accurate positioning of the positioning grid when it is carrying the yarn bobbin and cooperating with the drive assembly, thereby improving the stability and reliability of the entire feeding system.

[0022] As a further description of the above technical solution:

[0023] Two fixing blocks are fixedly connected to the top of the fixing base, and the outside of the rotating rod is rotatably connected to the inside of the fixing blocks.

[0024] The above technical solution provides a stable fulcrum for the rotating rod 1, and the fixing block 2 supports and positions the rotating rod 1, ensuring that the rotating rod 1 can rotate stably under the drive of the motor 1, thereby ensuring the smooth operation of the transmission components such as the sprocket 1 and the chain, and maintaining the stability of the power transmission of the feeding assembly.

[0025] As a further description of the above technical solution:

[0026] The top of the chain is fitted inside the outside of the second sprocket, and the front and rear sides of the movable column are slidably connected to the outside of the slide rail.

[0027] The above technical solution enables sprocket one, sprocket two and the chain to form a stable transmission, ensuring that the positioning grid moves up and down continuously and stably; on the other hand, it clarifies the cooperation relationship between the moving column and the slide rail, ensuring that the moving column slides smoothly along the slide rail under the drive of the electric push rod, so that the drive component one can accurately control the position of the gripper and realize the accurate gripping and transfer of the yarn package.

[0028] As a further description of the above technical solution:

[0029] The bottom of the air pump is fixedly connected to the top left side of the base, and the other end of the pipe is fixedly connected to the top of the gripper.

[0030] The above technical solution provides a stable air source by fixing the air pump to the base. The air is then transported to the gripper through a pipeline, which drives the gripper to open and close, providing power support for the gripper to grasp the yarn package. This ensures that the gripper can stably grasp and release the yarn package and is the key connection and power transmission part of the drive component to realize the yarn package grasping function.

[0031] This utility model has the following beneficial effects:

[0032] In this invention, the feeding platform structure with a combination of positioning grid and grating detection effectively standardizes the layout of manual feeding. Through real-time detection and prompting by the grating, the empty area caused by manual placement is reduced by more than 70% of the textile equipment, and the number of yarn packages that the drying equipment can hold at one time increases by about 40%, significantly improving the utilization rate of space resources and reducing the drying energy consumption cost per unit product. The double-layer linkage grating detection and adaptive pushing structure can accurately detect and eliminate empty areas during the material changing process of the automatic feeding equipment.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a precision drying device for packaged yarn, comprising a base 1, multiple fixed supports 2 fixedly connected to the top left side of the base 1, fixed plates 3 fixedly connected to the top of two fixed supports 2, a drive assembly 4 installed on the top of the fixed plates 3, a fixed seat 5 fixedly connected to the top of the base 1, a feeding assembly 6 installed on the top right side of the fixed seat 5, a fixed box 7 fixedly connected to the top right side of the base 1, a drive assembly 8 installed on the front side of the fixed box 7, and a drying oven 9 fixedly connected to the top of the fixed box 7. The hot air circulation inside the drying oven 9 ensures that the packaged yarn is evenly heated during the drying process, achieving precision drying and guaranteeing the drying quality and efficiency of the packaged yarn.

[0041] Drive assembly 4 includes an electric push rod 41, the bottom of which is fixedly connected to the top of one of the fixed plates 3. A moving column 43 is fixedly connected to the drive end of the electric push rod 41. A slide rail 42 is fixedly connected to the top of the fixed plate 3. A pipe 44 is fixedly connected inside the moving column 43, and an air pump 45 is fixedly connected to the rear side of the pipe 44. Multiple grippers 46 are fixedly connected to the bottom of the moving column 43. Driven by the electric push rod 41, the moving column 43 moves along the slide rail 42. The internal pipe 44 is used to transmit gas generated by the air pump 45, and the grippers 46 connected to the bottom are responsible for gripping the yarn package. The movable column 43 serves as an intermediate component connecting the electric push rod 41 and the gripper 46, integrating power transmission and gas transmission functions to realize the gripping and transfer operation of the yarn package. The bottom of the air pump 45 is fixedly connected to the top left side of the base 1, and the other end of the pipe 44 is fixedly connected to the top of the gripper 46. The air pump 45 generates pressure by compressing air and delivers the gas to the gripper 46 through the pipe 44, driving the gripper 46 to open and grip the yarn package. After the gripping is completed, the gas is released to close the gripper 46 and clamp the yarn package, ensuring that the yarn package will not fall during the transfer process.

[0042] Specifically, the electric push rod 41 precisely controls the moving column 43 to move along the slide rail 42 according to the command. The compressed gas generated by the air pump 45 is transmitted through the pipeline 44 to drive the gripper 46 to open and close precisely, so as to grab the yarn package on the positioning grid 611. After grabbing, the electric push rod 41 drives the yarn package to the designated position, ensuring that the yarn package is accurately positioned and stable without falling during the transfer process, so as to provide a reliable starting connection for the subsequent transmission and drying process.

[0043] Reference Figure 3 and Figure 4The feeding assembly 6 includes a motor 61, the bottom of which is fixedly connected to the top of the fixed base 5. A rotating rod 62 is fixedly connected to the drive end of the motor 61. A sprocket 63 is fixedly connected to the outside of the rotating rod 62, and a chain 64 is sleeved on the outside of the sprocket 63. A fixed frame 65 is fixedly connected to the top right side of the fixed base 5. Two fixing blocks 66 are fixedly connected to the top inner wall of the fixed frame 65. A rotating rod 67 is rotatably connected to the adjacent side of the two fixing blocks 66. A fixed rod 67 is fixed on the rotating rod 67. A fixed sprocket 68 engages with a chain 64, rotating under the drive of the chain 64. This provides support and guidance for the cyclical movement of the chain 64, ensuring its smoothness and reliability. A sprocket 68 is fixedly connected to the outside of a rotating rod 67, and a connecting block 610 is fixedly connected to the outside of the chain 64. A positioning grid 611 is fixedly connected to the left side of the connecting block 610. The positioning grid 611 is connected to the chain 64 via the connecting block 610 and moves up and down along a fixed rod 612 under the drive of the chain 64. It is used to hold the yarn package and detects the position and status of the yarn package via a miniature optical grating sensor 613 at the top. The structural design of the positioning grid 611 ensures the stability and accuracy of the yarn during the conveying process, while providing an installation position for the miniature grating sensor 613 to achieve precise detection and positioning of the yarn. Multiple fixing rods 612 are fixedly connected to the top of the fixing base 5, and multiple miniature grating sensors 613 are fixedly connected to the top of the positioning grid 611. When a yarn package is not placed in a certain grid, the corresponding grating sensor will detect a signal and issue a reminder through indicator lights or buzzers, guiding workers to replenish the yarn package in a timely manner. This reduces empty areas caused by manual placement, allowing the yarn package to be distributed more tightly and evenly on the drying equipment's bearing surface, improving space utilization. This also provides accurate yarn bobbin position information for subsequent grasping operations. Multiple fixed rods 612 are externally slidably connected to the inside of the positioning grid 611. The right side of the positioning grid 611 is slidably connected to the right side of the fixed frame 65. The top of the fixed seat 5 is fixedly connected to two fixed blocks 69. The rotating rod 62 is rotatably connected to the fixed block 69 to ensure its own rotational stability. At the same time, it transmits the power of the motor 61 to the sprocket 63, driving the chain 64 to move. The external rotating rod 62 is rotatably connected to the inside of the fixed block 69. The top of the chain 64 is internally sleeved on the outside of the sprocket 68. The front and rear sides of the moving column 43 are internally slidably connected to the outside of the slide rail 42.

[0044] Specifically, motor 61 drives rotating rod 62, which, through sprocket 63, chain 64, and sprocket 68, drives connecting block 610 and positioning grid 611 to move up and down along fixed rod 612, achieving orderly feeding of yarn packages. Fixed frame 65, fixed block 66, rotating rod 67, and fixed block 69 ensure stable transmission. The structural design of positioning grid 611 ensures stable yarn package conveying. Top micro-grating sensor 613 detects the position status of yarn packages in real time, prompting workers to replenish material, reducing empty areas, improving the space utilization of drying equipment, and providing accurate position information for precise gripping by drive component 4, ensuring efficient and orderly operation of the yarn package drying process.

[0045] Reference Figure 2 The second drive assembly 8 includes a load-bearing plate 81, a second motor 82 fixedly connected to the top of the load-bearing plate 81, a first rotating shaft 83 fixedly connected to the drive end of the second motor 82, and a conveyor belt 84 sleeved on the outside of the first rotating shaft 83. The first rotating shaft 83 and the second rotating shaft 85 provide support and rotation fulcrum for the conveyor belt 84. Through the cooperation of the two, the conveyor belt 84 can operate smoothly and transport the yarn package from the grabbing position to the drying oven 9. The second rotating shaft 85 is rotatably connected to the left side of the fixed box 7. The left side of the conveyor belt 84 is sleeved on the outside of the second rotating shaft 85. The outside of the first rotating shaft 83 is rotatably connected to the right side of the fixed box 7. The conveyor belt 84 receives the yarn package transferred from the first drive assembly 4 and transports the yarn package to the drying oven 9 at the top of the fixed box 7. The surface material and structural design of the conveyor belt 84 ensure that the yarn package will not slip or fall during the transport process. At the same time, its running speed and stability can meet the requirements of the drying operation for yarn package transport.

[0046] Specifically, motor 82, supported by rotating shaft 83 and rotating shaft 85, drives conveyor belt 84 to operate smoothly, receiving the yarn package transferred by drive component 4; conveyor belt 84, with its special surface material and structural design, ensures that the yarn package is stable and does not slip during the conveying process, and efficiently and accurately conveys the yarn package to the drying oven 9 at the top of the fixed box 7 at an appropriate speed and in a stable state, creating conveying conditions for the precise drying of the yarn package.

[0047] Working principle: When the motor 61 in the feeding assembly 6 starts, it drives the rotating rod 62 to rotate. The sprocket 63 outside the rotating rod 62 rotates accordingly, driving the sprocket 68 to rotate through the chain 64, causing the chain 64 to circulate. The connecting block 610 on the chain 64 drives the positioning grid 611 to move up and down along the fixed rod 612. Multiple miniature grating sensors 613 on the top of the positioning grid 611 detect the position and status of the yarn in real time. The grating sensors form a detection network, which can detect whether there is yarn in the grid in real time. When the worker is feeding, if there is no yarn in a certain grid, the corresponding grating sensor will detect the signal and issue a reminder through indicator lights or buzzers, etc., to guide the worker to replenish the yarn in time, thereby reducing the empty area caused by manual placement, so that the yarn can be distributed more tightly and evenly on the bearing surface of the drying equipment, improving the utilization rate of space resources. When the positioning grid 611 moves to the appropriate position, the electric push rod 41 of the drive assembly 4 starts, and its drive end drives the moving column 43 to move left and right along the slide rail 42. Once the moving column 43 has moved to the appropriate position, the air pump 45 supplies gas to the gripper 46 through the pipe 44. Under the pressure of the gas, the gripper 46 opens and grabs the yarn package on the positioning grid 611. After the gripping is completed, the electric push rod 41 retracts, causing the moving column 43 to rise and transfer the yarn package to the designated position.

[0048] When the motor 82 of the drive assembly 2 is started, it drives the rotating shaft 83 to rotate. The rotating shaft 83 drives the rotating shaft 85 to rotate through the conveyor belt 84, so that the conveyor belt 84 can operate. After the gripper 46 transfers the yarn package onto the conveyor belt 84, the conveyor belt 84 transports the yarn package to the drying oven 9 at the top of the fixed box 7.

[0049] After the yarn package is conveyed into the drying oven 9, the heating element inside the drying oven 9 starts to work to dry the yarn package. During the drying process, the yarn package is relatively fixed in position inside the drying oven 9. Through the circulation of hot air inside the drying oven 9, the yarn package is heated evenly to achieve precise drying.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
