Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn drying oven technology, and in particular to a yarn drying oven. Background Technology
[0002] The eight-basket constant temperature drying oven is a device used to determine the moisture regain or moisture content of various raw materials, semi-finished products and finished products such as cotton, linen, wool, silk and chemical fibers. It can also be used for other applications that require constant temperature drying.
[0003] The inventors discovered during routine use of the eight-basket constant temperature drying oven that when drying yarn, the yarn needs to be placed inside the drying basket for drying. Since the size of the drying basket is not fixed, the drying basket may not be able to be securely locked at one end of the drying tube for drying, which makes it inconvenient to dry the yarn and causes problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a yarn drying oven.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a yarn drying oven, comprising an oven, an oven tube provided inside the oven, a drying basket provided at the top of the oven tube, a through groove provided at the bottom of the drying basket, an operation switch and a display provided on the side of the oven, a clamping device provided at the top of the oven tube, the clamping device comprising a ring fixedly connected to the top of the oven tube, an air bladder fixedly connected to the inner wall of the ring, and a drying basket inserted inside the ring.
[0006] The effect achieved by the above components is that, under the action of the airbag, the drying basket is locked inside the ring, thereby achieving the function of clamping.
[0007] Preferably, the side of the ring is threaded with a screw, and one end of the screw is rotatably connected to an arc-shaped plate, which is a rubber plate.
[0008] The effect achieved by the above components is that, under the action of the screw, the arc-shaped plate can be pressed against the surface of the drying basket, thereby fixing the drying basket inside the ring.
[0009] Preferably, a round strip, which is a rubber strip, is fixedly connected to the side of the arc-shaped plate.
[0010] The effect achieved by the above components is that, under the action of the round bar, the arc plate will not directly contact the drying basket, thus avoiding the deformation of the drying basket.
[0011] Preferably, a round rod is slidably connected to the surface of the ring, and one end of the round rod is fixedly connected to the side of the arc-shaped plate.
[0012] The effect achieved by the above components is that, under the action of the round rod, the arc-shaped plate will not rotate with the rotation of the screw.
[0013] Preferably, the side of the arc-shaped plate is provided with a groove, and a roller is rotatably connected inside the groove.
[0014] The effects achieved by the above components are as follows: Under the action of the rollers, the friction between the arc-shaped plate and the inner wall of the ring is reduced, thus facilitating the movement of the arc-shaped plate. When it is necessary to clamp and fix the drying basket to the upper surface of the drying tube, the drying basket is inserted into the inside of the ring. Under the action of the airbag, the drying basket is stuck inside the ring, thus achieving the clamping effect. By turning the screw by hand, the arc-shaped plate is smoothly pressed against the surface of the drying basket under the action of the round rod. Under the action of the round bar, the arc-shaped plate does not directly contact the drying basket, avoiding the deformation of the drying basket. Under the action of the rollers, the friction between the arc-shaped plate and the inner wall of the ring is reduced, thus facilitating the movement of the arc-shaped plate, thereby achieving the clamping effect.
[0015] Preferably, a sealing device is provided on the top of the drying basket. The sealing device includes a sleeve rod sleeved on one end of the drying basket, and a retaining ring is fixedly connected to the inner wall of the sleeve rod. The retaining ring is a rubber ring.
[0016] The effect achieved by the above-mentioned components is that, under the action of the retaining ring, the sleeve rod is locked onto the surface of the drying basket, thereby sealing the drying basket and preventing the yarn from flying out of the drying basket.
[0017] Preferably, a gasket, which is a rubber ring, is fixedly connected to the top of the drying basket.
[0018] The effect achieved by the above components is that, under the action of the gasket, the sleeve rod will not directly contact the drying basket, thus avoiding the phenomenon of rigid contact.
[0019] Preferably, a locking rod is inserted into the side of the sleeve rod, a groove is formed on the surface of the drying basket, one end of the locking rod is inserted into the inside of the groove, and a spring is sleeved on the surface of the locking rod, with the two ends of the spring respectively fixedly connected to one end of the locking rod on the surface of the sleeve rod.
[0020] The aforementioned components achieve the following effects: The locking rod secures the sleeve to the surface of the drying basket, thus achieving a fixed position. The spring prevents the locking rod from slipping out of the groove. When the yarn is placed inside the drying basket, the sleeve is placed over the opening. The retaining ring secures the sleeve to the surface of the drying basket, sealing it and preventing the yarn from flying out. The washer prevents the sleeve from directly contacting the drying basket, avoiding rigid contact. The spring prevents the locking rod from slipping out of the groove, thus achieving a sealing effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a clamping device, when it is necessary to clamp and fix the drying basket to the upper surface of the drying tube, the drying basket is inserted into the inside of the ring. Under the action of the air bladder, the drying basket is stuck inside the ring, thus achieving the clamping effect. By turning the screw by hand, the arc-shaped plate is smoothly pressed against the surface of the drying basket under the action of the round rod. Under the action of the round bar, the arc-shaped plate does not directly contact the drying basket, avoiding the deformation of the drying basket. Under the action of the roller, the friction between the arc-shaped plate and the inner wall of the ring is reduced, thus facilitating the movement of the arc-shaped plate, thereby achieving the clamping effect. This solves the problem that drying baskets of different sizes are inconvenient to be clamped at one end of the drying tube for drying yarn. Attached Figure Description

[0027] Example 1, such as Figure 1-3As shown, a yarn drying oven 1 includes an oven 1 with a drying tube 6 inside. A drying basket 5 is positioned on the top of the drying tube 6, and a through groove is formed at the bottom of the drying basket 5. An operation switch 4 and a display are located on the side of the oven 1. A clamping device 2 is located on the top of the drying tube 6. When drying yarn needs to be dried in the oven 1, the yarn is placed inside the drying basket 5, the drying basket 5 is placed on top of the drying tube 6, and the oven 1 is started. The temperature of the oven 1 is controlled by a digital display instrument connected to a temperature sensor, and a hot air circulation system is used. Specifically, the air source is driven by a blower motor, which drives a fan through an electric heater to deliver hot air to a specially designed air duct before entering the working chamber of the oven 1. At the same time, used air is drawn into the air duct for recirculation and reheating. This design allows for better gas flow within the oven 1, accelerating the drying speed of the material and ensuring uniformity.
[0028] Reference Figure 2 The clamping device 2 includes a ring 21 fixedly connected to the top of the drying tube 6. An air bladder 22 is fixedly connected to the inner wall of the ring 21. A drying basket 5 is inserted inside the ring 21. Under the action of the air bladder 22, the drying basket 5 is clamped inside the ring 21, thus achieving the clamping function. A screw 23 is threadedly connected to the side of the ring 21. One end of the screw 23 is rotatably connected to an arc-shaped plate 25, which is a rubber plate. Under the action of the screw 23, the arc-shaped plate 25 can be pressed against the surface of the drying basket 5, thus fixing the drying basket 5 inside the ring 21. A round strip 26, which is a rubber strip, is fixedly connected to the side of the arc-shaped plate 25. Under the action of the round strip 26, the arc-shaped plate 25 will not directly contact the drying basket 5, avoiding deformation of the drying basket 5. A round rod 24 is slidably connected to the surface of the ring 21. One end of the round rod 24 is fixedly connected to the side of the arc-shaped plate 25. Under the action of the round rod 24, the arc-shaped plate 25 is pressed against the surface of the drying basket 5, thus fixing the drying basket 5 inside the ring 21. The curved plate 25 does not rotate with the screw 23. A groove is provided on the side of the curved plate 25, and a roller 27 is rotatably connected inside the groove. Under the action of the roller 27, the friction between the curved plate 25 and the inner wall of the ring 21 is reduced, thus facilitating the movement of the curved plate 25. When it is necessary to clamp and fix the drying basket 5 to the upper surface of the drying tube 6, the drying basket 5 is inserted into the ring 21. Under the action of the airbag 22, the drying basket 5 is locked inside the ring 21, thus achieving the clamping effect. By turning the screw 23 by hand, the curved plate 25 is smoothly pressed against the surface of the drying basket 5 under the action of the round rod 24. Under the action of the round bar 26, the curved plate 25 does not directly contact the drying basket 5, avoiding deformation of the drying basket 5. Under the action of the roller 27, the friction between the curved plate 25 and the inner wall of the ring 21 is reduced, thus facilitating the movement of the curved plate 25, thereby achieving the clamping effect.
[0029] Reference Figure 3A sealing device 3 is provided on the top of the drying basket 5. The sealing device 3 includes a sleeve rod 31 sleeved on one end of the drying basket 5. A retaining ring 32 is fixedly connected to the inner wall of the sleeve rod 31. The retaining ring 32 is a rubber ring. Under the action of the retaining ring 32, the sleeve rod 31 is locked onto the surface of the drying basket 5, thereby achieving the phenomenon of sealing the drying basket 5 and preventing the yarn from flying out of the drying basket 5. A washer 33 is fixedly connected to the top of the drying basket 5. The washer 33 is a rubber ring. Under the action of the washer 33, the sleeve rod 31 will not directly contact the drying basket 5, avoiding the phenomenon of rigid contact. A retaining rod 34 is inserted into the side of the sleeve rod 31. A groove is opened on the surface of the drying basket 5. One end of the retaining rod 34 is inserted into the inside of the groove. A spring 35 is sleeved on the surface of the retaining rod 34. The sleeve rod 31 and the clamp rod 34 are fixedly connected to each other on the surface of the sleeve rod 31. Under the action of the clamp rod 34, the sleeve rod 31 can fix the surface of the drying basket 5, thereby achieving the fixing function. Under the action of the spring 35, the clamp rod 34 will not slip out of the groove. When the yarn is put into the drying basket 5, the sleeve rod 31 is sleeved on the opening of the drying basket 5. Under the action of the retaining ring 32, the sleeve rod 31 is clamped on the surface of the drying basket 5, thereby sealing the drying basket 5 and preventing the yarn from flying out of the drying basket 5. Under the action of the washer 33, the sleeve rod 31 will not directly contact the drying basket 5, avoiding the phenomenon of rigid contact. Under the action of the spring 35, the clamp rod 34 will not slip out of the groove, thereby achieving the sealing function.
[0030] Working principle: When the yarn drying oven 1 needs to be used to dry yarn, the yarn is placed inside the drying basket 5, which is then placed on top of the drying tube 6. The oven 1 is then started, and the temperature is controlled by a digital display instrument connected to a temperature sensor. A hot air circulation system is used. Specifically, the air source is driven by a blower motor, which drives the impeller through an electric heater, delivering hot air to a specially designed air duct before entering the working chamber of the oven 1. Simultaneously, used air is drawn into the air duct for recirculation and reheating. This design improves gas flow within the oven 1, accelerating material drying and ensuring uniformity. When the drying basket 5 needs to be clamped and fixed to the upper surface of the drying tube 6, it is inserted into the ring 21. Under the action of the air bladder 22, the drying basket 5 is secured within the ring 21, achieving the clamping effect. Tightening the screw 23 by hand causes the arc-shaped plate 25 to be smoothly pressed against the surface of the drying basket 5 under the action of the round rod 24. The round bar 26 prevents the arc-shaped plate 25 from directly contacting the drying basket 5, avoiding deformation. The roller 27 further ensures the arc-shaped plate... The friction between the curved plate 25 and the inner wall of the ring 21 is reduced, which facilitates the movement of the curved plate 25 and achieves the clamping effect. When the yarn is put into the drying basket 5, the sleeve rod 31 is sleeved at the opening of the drying basket 5. Under the action of the retaining ring 32, the sleeve rod 31 is stuck on the surface of the drying basket 5, thereby sealing the drying basket 5 and preventing the yarn from flying out of the drying basket 5. Under the action of the washer 33, the sleeve rod 31 will not directly contact the drying basket 5, avoiding the phenomenon of rigid contact. Under the action of the spring 35, the retaining rod 34 will not slip out of the groove, thereby achieving the sealing effect.
