TECHNICAL FIELD

[0001] The application relates to the technical field of fireproof cotton yarn production, and in particular to a drying device for fireproof cotton yarn production. BACKGROUND

[0002] In the manufacturing process of cotton yarn, different properties such as waterproofness, antibacterial property and flame retardancy are required according to the fields in which the fabric products are used, and for the fabric required by the fire department, the corresponding textile fabric with flame retardancy is required to improve the flame retardancy.

[0003] A production method of flame-retardant tear-resistant fabric is disclosed in Chinese Patent Application No. 201910126600.5, which comprises: warping: winding 80-95% of the total warp count of cotton yarn onto a first beam, and winding 5-20% of the total warp count of composite reinforcing yarn onto a second beam; sizing: sizing the cotton yarn by using a double-dipping single-press sizing process to adhere the cotton yarn hair, improve the bunching property of the cotton yarn, increase the smoothness of the cotton yarn surface, and enhance the breaking strength of the cotton yarn to ensure smooth weaving; threading and reeding: threading and reeding the cotton yarn and the composite reinforcing yarn; weaving: double-axis weaving the first beam and the second beam to obtain the fabric; singeing: singeing the fabric; pretreatment: enzyme sizing and cold stacking pretreatment of the fabric; scouring and bleaching: treating the fabric according to the one-step scouring and bleaching method; 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: sequentially drying, preshrinking and finishing the fabric. The present application effectively improves the tear strength of the flame-retardant fabric.

[0004] In the process of preparing the fabric, the corresponding drying device can modify the fabric to improve the corresponding flame retardant effect, so the effect of drying is very important. Generally, the yarn is input into the drying cylinder, passes through the drying roller in a zigzag shape, and is dried by hot air inside. After the hot air is introduced into the drying cylinder, it performs hot air drying along a fixed path, but the continuous and stable hot air path will reduce the drying effect of the fabric facing away from the hot air input direction, which will affect the quality of the subsequent products. SUMMARY

[0005] In order to improve the chaos of hot air input into the drying cylinder, the application provides a drying device for fireproof cotton yarn production.

[0006] The application provides a drying device for fire-fighting cotton yarn production, which adopts the following technical scheme: a drying device for fire-fighting cotton yarn production, comprising an oven, the oven is provided with a plurality of air outlet modules, each air outlet module is a hollow structure, the lower side of each air outlet module is provided with a air outlet channel, each air outlet module is movably provided with a distribution block on one side close to the air outlet channel, the distribution block is provided with b blocking balls, b is less than a; the blocking balls are used to close a part of the air outlet channels after the distribution block moves.

[0007] By adopting the above technical scheme, different air outlet modules are arranged in the oven according to different drying requirements. For each air outlet module, the hot air in the distribution block needs to be discharged through the air outlet channel each time. However, the distribution block moves every certain time, so that the blocking balls move to the upper side of the air outlet channel at random and close the air outlet channel, so that the air outlet path in the air outlet module changes each time, thereby increasing the hot air turbulence in the drying cylinder and improving the drying effect.

[0008] Preferably, a lifting structure extending in the axial direction is arranged in each air outlet channel, the lifting structure is used to drive the blocking ball to open the air outlet channel, and air flows in the air outlet channel and passes through the lifting structure.

[0009] Preferably, the distribution block is provided with a matching channel corresponding to the air outlet channel, the blocking ball is used to be clamped at the end of the matching channel, the end of the matching channel is provided with a semicircular ball-shaped accommodation groove, and the bottom of the accommodation groove is provided with a communication hole communicating with the air outlet channel.

[0010] By adopting the above technical scheme, the blocking ball falls into the matching channel and blocks the air outlet channel. The matching channel that does not fall into the blocking ball can take in air through the communication 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 on the solid part; the upper side of the distribution block is a hollow structure, the top wall of the distribution block is provided with 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 scheme, when the blocking ball is separated from the matching channel, the distribution block is rotated for one or more turns, the blocking ball collides with the upper collision point to form random movement, and when the rotation is stopped, the blocking ball falls into the matching channel (or individual blocking balls stay on the upper side of the solid part), so that the air outlet position is changed.

[0013] Preferably, the end of the collision point is provided with a vertically arranged abutting rod, the abutting rod is made of rubber, and the end of the abutting rod is used to collide with the blocking ball.

[0014] Preferably, the solid part has an arc-shaped protrusion between adjacent matching channels for guiding the blocking ball to fall into the matching channel.

[0015] Preferably, the lifting structure includes a jacking column arranged at the center axis of the air outlet channel, a telescopic sleeve sleeved and slidingly arranged at the upper end of the jacking column, the jacking column has a communication air duct communicating with the telescopic sleeve, the telescopic sleeve has a first magnet at the end, and the blocking ball has a second magnet embedded therein and repelling the first magnet.

[0016] By using the above technical scheme, after the telescopic sleeve moves upward, the blocking ball will be gradually pushed away from the matching channel by the repelling magnetic force, and during the rotation, the blocking ball will not fall into the matching channel temporarily, and only after the telescopic sleeve retracts, the blocking ball will fall into the matching channel.

[0018] Preferably, the telescopic sleeve is sleeved with a reset spring inside and outside, one end of the reset 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 repelling 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 has at least one of the following beneficial technical effects:

[0021] 1. Different air outlet modules are arranged in the oven, and for each air outlet module, the hot air in the distribution block needs to be discharged through the air outlet channel each time, but at certain intervals, the distribution block moves, so that the blocking ball moves to the upper side of the random air outlet channel to close it, thereby changing the air outlet path in each air outlet module, increasing the degree of hot air chaos in the drying cylinder, and improving the drying effect.

[0022] 2. After the blocking ball separates from the matching channel, the distribution block is rotated for one or more turns, and the blocking ball will hit the upper collision point to form random movement, and when the rotation stops, the blocking ball will fall into the matching channel to change the air outlet position.

[0023] 3. After inflating the air passage, the telescopic sleeve will gradually push the blocking ball away from the mating channel through the repulsive magnetic force as it moves upward. During the rotation, the blocking ball will not fall into the mating channel temporarily. Only after the distribution block stops moving and the telescopic sleeve retracts will the blocking ball fall into the mating channel. Attached Figure Description

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a drying device for the production of fire-fighting cotton yarn, referring to... Figure 1 , Figure 2 The oven includes an oven 100, which contains several air outlet modules 110. Each air outlet module 110 has a hollow structure. Specifically, depending on the actual situation, the air outlet module 110 can be placed in any position, such as on the side. However, due to the structural relationship in this embodiment, the air outlet modules 110 must be placed horizontally.

[0033] Reference Figure 2 , Figure 3The lower side of the air outlet module 110 has a air outlet channel 111, and each air outlet module 110 has a distribution block 112 movably arranged on the side close to the air outlet channel 111. 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 rotationally connected to the air outlet module 110, and the driving mode is a motor 113. The output shaft of the motor 113 is connected to the center axis of the distribution block 112. After the distribution block 112 is moved, the blocking balls 140 are used to close a part of the air outlet channel 111. It is worth noting that the input source pipeline connected to the distribution block 112 will rotate as a whole.

[0034] In this embodiment, referring to Figure 4 、 Figure 5 , the air outlet channel 111 is arranged on the air outlet module 110 along the spiral line. Each air outlet channel 111 is provided with a lifting structure that can move along the axial direction. The lifting structure is used to drive the blocking ball 140 to open the air outlet channel 111, and the air flow in the air outlet channel 111 passes through the lifting structure.

[0035] The distribution block 112 has a matching channel 114 corresponding to the air outlet channel 111. The blocking ball 140 is used to be clamped at the end of the matching channel 114. The end of the matching channel 114 has a semicircular ball-shaped accommodation groove 115. The bottom of the accommodation groove 115 has a communication hole 116 that communicates with the air outlet channel 111. The lower side of the distribution block 112 is a solid part, and the matching channel 114 is arranged on 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.

[0036] Referring to Figure 5 、 Figure 6 , the end of the collision point 117 has a vertically arranged contact rod 118. The contact rod 118 is made of rubber, and the end of the contact rod 118 is used to impact the blocking ball 140. The solid part has an arc-shaped protrusion 119 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 protrusion 119 is also arranged along the spiral line. There is one arc-shaped protrusion 119 between every two adjacent matching channels 114 along the spiral line.

[0037] Specifically, every time interval, for example, after five minutes, first, the lifting structure moves so that the blocking ball 140 is disengaged from the fitting channel 114, at this time the blocking ball 140 returns to the upper side of the solid part, and then the distribution block 112 rotates, in the process of rotation, the blocking ball 140 may hit the arc-shaped protrusion 119 or the collision point 117, and when it hits the resistance rod 118, it will move in an uncertain direction by the recovery state after bending. When the distribution block 112 rotates one circle (or more circles), at this time the lifting structure retracts and does not act on the blocking ball 140, at this time the arc-shaped protrusion 119 will make the blocking ball 140 move into the fitting channel 114 as much as possible, of course, there is also a possibility that the blocking ball 140 will be located on the upper side of the solid part, but after the subsequent hot air is introduced, it will eventually fall into the fitting channel 114 and be resisted at the bottom of the accommodation groove 115 under the action of hot air. After each rotation of the distribution block 112, a random blocking ball 140 will fall and block the air outlet 111, so that the air outlet module 110 can intermittently output different air outlet modes.

[0038] In the embodiment, the lifting structure includes a jacking column 120 arranged at the center axis position of the air outlet 111, a telescopic sleeve 121 sleeved and slidingly arranged at the upper end of the jacking column 120, the jacking column 120 has a communication air channel 122 communicated to the inside of the telescopic sleeve 121, the end of the telescopic sleeve 121 has a first magnet 123, and the blocking ball 140 is embedded with a second magnet 124 repelling the first magnet 123. The lowermost end of the jacking column 120 will protrude out of the air outlet 111, and a gas pipe 125 in a spiral shape is arranged at the lower side of the air outlet module 110. One end of the gas pipe 125 will pass through the outer wall of the drying cylinder, and when air passes through the gas pipe 125, it will push the telescopic sleeve 121 upward through the communication air channel 122.

[0039] When the telescopic sleeve 121 rises to the highest height, the repelling force between the first magnet 123 and the second magnet 124 makes the blocking ball 140 disengage from the fitting channel 114, and the upper end of the telescopic sleeve 121 is located in the air outlet 111. In this way, in the process of rotating the distribution block 112, it will not interfere with the telescopic sleeve 121. And if the sealing between the telescopic sleeve 121 and the jacking column 120 decreases during operation, so that the telescopic sleeve 121 loses the lifting function, under the condition that a small part of the blocking ball 140 remains in some fitting channels 114, it will not affect the overall ability to continue to form a random air outlet effect.

[0040] The inner wall of the air outlet duct 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 the vertical state, and meanwhile, the auxiliary frame 130 and the inner wall of the air outlet duct 111 have a space for gas flow. The telescopic sleeve 121 is sleeved with a reset spring 131 inside and outside, one end of the reset 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, the telescopic sleeve 121 will move upward, the bottom outer side of the telescopic sleeve 121 has a flange 132, which will be connected to the reset spring 131 to make it compressively deform. When the telescopic sleeve 121 needs to be reset, the air pipe 125 is not inflated any more, and the reset spring 131 can make the telescopic sleeve 121 reset.

[0041] The embodiments of the present specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
