Description

Technical Field

[0001] The present application relates to the technical field of fire-fighting cotton yarn production, and in particular to a drying device for fire-fighting cotton yarn production. Background Art

[0002] In the production process of cotton yarn, different properties need to be provided according to the different fields in which the fabric products are used, such as waterproof, antibacterial, flame retardant, etc. Among them, for the fabrics required for fire fighting, it is necessary to use textile fabrics with flame retardant properties to improve the flame retardant performance.

[0003] The Chinese invention patent with application number 201910126600.5 discloses a method for producing flame-retardant and tear-resistant fabrics, including: warping: winding cotton yarn accounting for 80%-95% of the total warp roots onto a first weaving shaft, and winding composite reinforcing yarn accounting for 5%-20% of the total warp roots onto a second weaving shaft; sizing: sizing the cotton yarn using a double-dip single-press sizing process to flatten the cotton yarn hairiness, improve the bundling of the cotton yarn, increase the surface smoothness of the cotton yarn, and enhance the breaking strength of the cotton yarn to ensure smooth weaving. The invention comprises the following steps: drawing in and reeding: drawing in and reeding the cotton yarn and the composite reinforced yarn; weaving: using the first weaving beam and the second weaving beam to perform biaxial weaving to obtain the fabric; singeing: singeing the fabric; pretreatment: performing enzyme pulp cold pile pretreatment on the fabric; scouring and bleaching: treating the fabric in a one-step method of scouring and bleaching; mercerizing: mercerizing the fabric on a straight roller mercerizing machine; dyeing: dyeing the fabric; flame retardant: impregnating the fabric with a flame retardant finishing liquid; drying, preshrinking and finished product: drying, preshrinking and finished product of the fabric in sequence. The invention effectively improves the tear strength of the flame retardant fabric.

[0004] During the preparation of fabrics, the corresponding drying device can modify the fabrics to improve the corresponding flame retardant effect, so the drying effect is very important. In general, the yarn is input into the drying drum, passed through the drying roller in a zigzag shape, and then dried with hot air inside. After the hot air enters the drying drum, it is dried along a fixed path, but the continuous and stable hot air path will reduce the drying effect for the fabrics facing away from the hot air input direction, which will affect the subsequent quality of the product. Summary of the invention

[0005] In order to increase the degree of disorder of hot air input into a drying drum, the present application provides a drying device for producing fire-fighting cotton yarn.

[0006] The present application provides a drying device for the production of fire-fighting cotton yarn, which adopts the following technical solution: a drying device for the production of fire-fighting cotton yarn, comprising an oven, wherein the oven has a plurality of air outlet modules, each of the air outlet modules is a hollow structure, and the lower side of the air outlet module has a air outlet duct, and each of the air outlet modules is also provided with a distribution block movably arranged on a side close to the air outlet duct, wherein the distribution block has b blocking balls, and b is smaller than a; after the distribution block is moved, the blocking ball is used to close a portion of the air outlet duct.

[0007] By adopting the above technical solution, different air outlet modules are arranged in the drying oven in response to different drying requirements. For each air outlet module alone, the hot air introduced into the distribution block needs to be discharged through the air outlet duct each time. However, at regular intervals, the distribution block moves so that the blocking ball moves to the upper side of the random air outlet duct to close it, thereby changing the air outlet path in the air outlet module each time, thereby increasing the degree of chaos of the hot air in the drying drum and improving the drying effect.

[0008] Preferably, a lifting structure with an axial telescopic stroke is provided in each of the air outlets, and the lifting structure is used to drive the blocking ball to open the air outlet, and the air in the air outlet flows and passes through the lifting structure.

[0009] Preferably, the distribution block has a matching channel corresponding to the air outlet channel one by one, the blocking ball is used to snap into the end of the matching channel, the end of the matching channel has a semi-spherical receiving groove, and the bottom of the receiving groove has a connecting hole connected to the air outlet channel.

[0010] By adopting the above technical solution, after the blocking ball falls into the matching channel, it will block the air outlet channel accordingly, and the matching channel that has not fallen into the blocking ball will let in air through the connecting hole.

[0011] Preferably, the distribution block is rotatably connected in the oven, the lower side of the distribution block is a solid part, and the matching channel is arranged in the solid part; the upper side of the distribution block is a hollow structure, and the top wall of the distribution block has a plurality of collision points, and the distance between the end of the collision point and the solid part is greater than the diameter of the blocking ball.

[0012] By adopting the above technical solution, when the blocking ball leaves the matching channel, the distribution block is rotated one or more circles, and the blocking ball will hit the upper collision point, forming a random movement. When the rotation stops, the blocking ball will fall into the matching channel (it is not ruled out that some blocking balls stay on the upper side of the solid part), thereby realizing the change of the air outlet position.

[0013] Preferably, the end of the collision point has a vertically arranged resistance rod, the resistance rod is made of rubber, and the end of the resistance rod is used to impact the blocking ball.

[0014] Preferably, an arc-shaped protrusion is provided on the solid portion and between adjacent matching channels, for guiding the blocking ball to fall into the matching channels.

[0015] Preferably, the lifting structure includes a lifting column arranged at the central axis position of the air outlet duct, a telescopic sleeve sleeved and slidably arranged on the upper end of the lifting column, the lifting column has a connecting air passage connected to the telescopic sleeve, the end of the telescopic sleeve has a first magnet, and the sealing ball is embedded with a second magnet that repels the first magnet.

[0016] By adopting the above technical solution, after inflating the connecting airway, the telescopic sleeve will gradually push the blocking ball away from the matching channel through the repulsive magnetic force after moving upward, and during the rotation process, no blocking ball will temporarily fall into the matching channel. Only after the distribution block stops moving and the telescopic sleeve retracts, the blocking ball will fall into the matching channel.

[0017] Preferably, an auxiliary frame for the telescopic sleeve to pass through is fixedly provided on the inner wall of the air outlet duct, and a space for gas flow is provided between the auxiliary frame and the inner wall of the air outlet duct.

[0018] Preferably, a return spring is provided inside and outside the telescopic sleeve, one end of the return spring is fixedly connected to the outer wall of the telescopic sleeve, and the other end is fixedly connected to the auxiliary frame.

[0019] Preferably, when the telescopic sleeve rises to the highest height, the repulsive force between the first magnet and the second magnet causes the blocking ball to separate from the matching channel, and the upper end of the telescopic sleeve is located in the air outlet channel.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. Different air outlet modules are arranged in the oven. For each air outlet module, the hot air introduced into the distribution block needs to be discharged through the air outlet duct each time. However, at regular intervals, the distribution block moves, so that the blocking ball moves to the upper side of the random air outlet duct to close it, so that the air outlet path in the air outlet module changes each time, thereby increasing the degree of chaos of the hot air in the drying cylinder and improving the drying effect. 2. When the blocking ball leaves the matching channel, rotate the distribution block one or more times, the blocking ball will hit the upper collision point, forming a random movement. When the rotation stops, the blocking ball will fall into the matching channel to achieve the change of the air outlet position; 3. After inflating the connecting airway, the telescopic sleeve will gradually push the blocking ball away from the matching channel through the repulsive magnetic force after moving upward, and during the rotation process, no blocking ball will fall into the matching channel temporarily. Only after the distribution block stops moving and the telescopic sleeve retracts, the blocking ball will fall into the matching channel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The present application discloses a drying device for producing fire-fighting cotton yarn, referring to Figure 1 , Figure 2 , including an oven 100, wherein the oven 100 has a plurality of air outlet modules 110, each of which is a hollow structure. Specifically, according to actual conditions, the air outlet modules 110 can be set at any position, and the air outlet modules 110 can be set at the side. However, due to the structural relationship in this embodiment, the air outlet modules 110 need to be placed horizontally.

[0025] Reference Figure 2 , Figure 3, the lower side of the air outlet module 110 has a air outlet duct 111, and a distribution block 112 is movably provided in each air outlet module 110 and located on a side close to the air outlet duct 111, and the distribution block 112 has b blocking balls 140, and b is less than a. In this embodiment, b is 0.5a. Specifically, the distribution block 112 is rotatably connected to the air outlet module 110, and is driven by a motor 113, and the output shaft of the motor 113 is connected to the central axis of the distribution block 112. After the distribution block 112 is activated, the blocking ball 140 is used to close a portion of the air outlet duct 111. It is worth noting that the input source pipeline connected to the distribution block 112 will rotate with the whole.

[0026] In this embodiment, refer to Figure 4 , Figure 5 The air outlet 111 is arranged along the vortex line on the air outlet module 110. Each air outlet 111 is provided with a lifting structure with an axial telescopic stroke, and the lifting structure is used to drive the blocking ball 140 to open the air outlet 111, and the air in the air outlet 111 flows and passes through the lifting structure.

[0027] The distribution block 112 has a matching channel 114 corresponding to the air outlet 111. The blocking ball 140 is used to be snapped to the end of the matching channel 114. The end of the matching channel 114 has a semi-spherical receiving groove 115. The bottom of the receiving groove 115 has a connecting hole 116 connected to the air outlet 111. The lower side of the distribution block 112 is a solid part. The matching channel 114 is arranged in the solid part. The upper side of the distribution block 112 is a hollow structure. The top wall of the distribution block 112 has a plurality of collision points 117. The distance between the end of the collision point 117 and the solid part is greater than the diameter of the blocking ball 140.

[0028] Reference Figure 5 , Figure 6 The end of the collision point 117 has a vertically arranged abutment rod 118, which is made of rubber. The end of the abutment rod 118 is used to hit the blocking ball 140. An arc-shaped protrusion 119 is provided on the solid part and located between adjacent matching channels 114, which is used to guide the blocking ball 140 to fall into the matching channel 114. In this embodiment, the arc-shaped protrusions 119 are also arranged along the spiral line. An arc-shaped protrusion 119 is provided between each two matching channels 114 adjacent to each other along the spiral line.

[0029] Specifically, at regular intervals, for example, after five minutes, the lifting structure first moves to make the blocking ball 140 disengage from the matching channel 114, and the blocking ball 140 returns to the upper side of the solid part, and then the distribution block 112 rotates. During the rotation, the blocking ball 140 may hit the arc-shaped protrusion 119 or the collision point 117. When it hits the resistance rod 118, it will be bent and restored to a state, so that the blocking ball 140 moves in an uncertain direction. After the distribution block 112 rotates one circle (or multiple circles), the lifting structure retracts and does not act on the blocking ball 140. At this time, the arc-shaped protrusion 119 will try to make the blocking ball 140 move into the matching channel 114. Of course, it is also possible that the blocking ball 140 will be located on the upper side of the solid part, but after the hot air is introduced later, it will eventually fall into the matching channel 114 and resist the bottom of the accommodating groove 115 under the action of the hot air. Each time the distribution block 112 rotates, the blocking balls 140 will randomly fall and block the air outlet duct 111 , so that the air outlet module 110 can intermittently output different air outlet modes.

[0030] In this embodiment, the lifting structure includes a lifting column 120 arranged at the central axis position of the air outlet 111, a telescopic sleeve 121 sleeved and slidably arranged on the upper end of the lifting column 120, a connecting airway 122 connected to the telescopic sleeve 121 is provided in the lifting column 120, a first magnet 123 is provided at the end of the telescopic sleeve 121, and a second magnet 124 that repels the first magnet 123 is embedded in the blocking ball 140. The lower end of the lifting column 120 will extend out of the air outlet 111, and a spiral air pipe 125 is provided at the lower side of the air outlet module 110. One end of the air pipe 125 will pass through the outer wall of the drying drum, and when the air pipe 125 is ventilated, it will push the telescopic sleeve 121 upward through the connecting airway 122 to move upward.

[0031] When the telescopic sleeve 121 rises to the highest height, the repulsive force between the first magnet 123 and the second magnet 124 causes the blocking ball 140 to leave the matching channel 114, and the upper end of the telescopic sleeve 121 is located in the air outlet 111. In this way, during the rotation of the distribution block 112, there will be no interference with the telescopic sleeve 121. In addition, if the sealing between the telescopic sleeve 121 and the lifting column 120 decreases during operation, causing the telescopic sleeve 121 to lose its lifting function, due to the large number of blocking balls 140, a small part of the blocking balls 140 remain in some matching channels 114, which will not affect the overall ability to continue to form a random air outlet effect.

[0032] The inner wall of the air outlet 111 is fixedly provided with an auxiliary frame 130 for the telescopic sleeve 121 to pass through. The auxiliary frame 130 can guide the movement of the telescopic sleeve 121 to keep it in a vertical state, and there is a space for gas flow between the auxiliary frame 130 and the inner wall of the air outlet 111. A return spring 131 is arranged inside and outside the telescopic sleeve 121. One end of the return spring 131 is fixedly connected to the outer wall of the telescopic sleeve 121, and the other end is fixedly connected to the auxiliary frame 130. When the air pipe 125 is inflated internally, the telescopic sleeve 121 will move upward, and the outer side of the bottom of the telescopic sleeve 121 has a flange 132, which will be connected to the return spring 131 to compress and deform it. When the telescopic sleeve 121 needs to be reset, the air pipe 125 is no longer inflated, and the return spring 131 can be used to reset the telescopic sleeve 121.

[0033] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
