Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a textile drying equipment. Background Art

[0002] Textile drying is an important part of the textile processing process, which aims to remove moisture from textiles to ensure product quality and smooth subsequent processing. Common textile drying methods include hot air drying, infrared drying, microwave drying, vacuum drying, etc. Among them, hot air drying is to blow hot air directly on textiles to accelerate the evaporation of moisture and dry the textiles. Hot air drying has the advantage of fast drying speed and is often suitable for drying continuously produced textiles.

[0003] For example, the textile penetration drying device disclosed in the patent application document with application publication number CN103954110A includes an oven and a feed roller and a discharge roller respectively arranged at both ends of the oven, a conveying mechanism is provided between the feed roller and the discharge roller in the oven, an air supply channel connected to the heater is provided directly above the conveying mechanism, the air supply channel is connected to the circulating fan, the conveying mechanism includes three round mesh rollers arranged in sequence along the conveying direction of the textile, a plurality of air vents penetrating through the thickness direction of the round mesh roller are provided on the cylinder wall of the round mesh roller, a fixed sealing intercepting plate is provided in the round mesh roller, the sealing intercepting plate divides the space in the round mesh roller into a working area and a non-working area separated up and down, and a suction fan is provided in the working area.

[0004] When the device is in use, each circulating fan blows hot air toward the textiles on each round screen drum, and the suction fan in the round screen drum sucks the hot air into the round screen drum, so that the hot air penetrates the textiles, thereby better drying the textiles. However, the device adopts the method of introducing hot air from the outside into the round screen drum to allow the hot air to penetrate the textiles. It is necessary to set fans on both the inside and outside of the round screen drum to guide the hot air circulation. The number of fans used is large, and the equipment cost is high. The hot air blown out by the circulating fan cannot be completely sucked into the round screen drum by the corresponding suction fan to dry the textiles, resulting in heat loss. At the same time, when the conveying mechanism in the device conveys the textiles, the textiles are always attached to the outer wall of the round screen drum, which will cause the textiles to wrinkle and suffer more mechanical damage. The textiles are strongly dried by the penetrating hot air during the movement. For relatively delicate textiles, it is easy to cause high-temperature damage to the internal structure of the textiles, affecting the quality of the textiles. Summary of the invention

[0005] The present invention provides a textile drying device to solve the technical problems that the textile drying device in the prior art needs to use more fans when drying textiles, which leads to increased equipment cost, and the textiles are easily wrinkled and damaged due to long-term contact with the drum for strong drying.

[0006] In order to solve the above problems, the present invention provides a textile drying device adopting the following technical solutions:

[0007] A textile drying device comprises a box body, a feed port is arranged on the left side of the box body, a discharge port is arranged on the right side of the box body, a feed roller and a discharge roller whose rotation axes both extend in the front-back direction are arranged in the box body, the feed roller is located beside the feed port, the discharge roller is located beside the discharge port, a conveying mechanism is arranged between the feed roller and the discharge roller, the conveying mechanism comprises a first matching roller group and a second matching roller group arranged at intervals from left to right, the first matching roller group comprises a first drying roller and a first guide roller arranged at intervals from top to bottom, a plurality of first vents are arranged on the cylinder wall of the first drying roller, a first hot air unit is arranged on the box body, and an air outlet end of the first hot air unit is communicated with an inner cavity of the first drying roller; the second matching roller group comprises a second guide roller and a second drying roller arranged at intervals from top to bottom, a plurality of second vents are arranged on the cylinder wall of the second drying roller, a second hot air unit is arranged on the box body, and an air outlet end of the second hot air unit is communicated with an inner cavity of the second drying roller;

[0008] The first guide roller is used to support the textile introduced by the feed roller and guide the textile to be transported toward the second drying roller. The second drying roller is used to allow the textile led out by the first guide roller to be wound from bottom to top and guide the textile to be transported toward the first drying roller. The first drying roller is used to allow the textile led out by the second drying roller to be wound from bottom to top and guide the textile to be transported toward the second guide roller. The second guide roller is used to be pressed above the textile led out by the first drying roller and guide the textile to be transported toward the discharge roller.

[0009] By adopting the above technical scheme, the hot air is blown out from the inside of the drying roller to the outside so that the hot air penetrates the textiles wound on the drying roller to dry the textiles. Compared with the prior art method of drying the textiles by sucking hot air from the outside of the roller into the inside of the roller, there is no need to set fans on both the inside and outside of the drying roller, the number of fans used is smaller, the equipment cost is lower, and at the same time, the air blown out from the drying roller is almost all blown onto the textiles, so the heat loss is lower.

[0010] During the conveying of textiles, the first drying roller and the second drying roller are in contact with the front and back sides of the textiles respectively to dry the textiles, so that the drying is more uniform. The textiles will not always be in contact with the drying rollers during the movement, but there is a part that can be suspended outside the drying rollers for movement, so the mechanical damage generated during the conveying process is smaller and the wrinkles generated are fewer. When the textiles move to the outside of the drying rollers, they can be strongly dried by the hot air blown out of the drying rollers, and the drying temperature will decrease after leaving the drying rollers, so that the textiles will not be in a state of being strongly dried all the time, and the internal structure of the textiles can be prevented from being degenerated under the action of continuous high temperature, resulting in high-temperature damage to the textiles. The textiles leaving the drying rollers can still be blown by the hot air blown out from the other side of the drying rollers, so that the hot air blown out by the drying rollers can be fully utilized, so that the textiles are in a state of being continuously dried, and the drying efficiency is high.

[0011] Furthermore, inner rollers are coaxially penetrated on the inner sides of the first drying roller and the second drying roller, and a plurality of inner air holes are provided on the half-side wall of the inner roller in the circumferential direction. The air outlet ends of the first hot air unit and the second hot air unit are respectively connected with the inner cavities of the two inner rollers, and arc filter boxes are coaxially provided on the outer sides of the two inner rollers. The arc filter boxes are tightly attached to the corresponding inner rollers and are spaced from the corresponding drying rollers. The arc filter box in the first drying roller is located on the right side of the corresponding inner roller, and the arc filter box in the second drying roller is located on the left side of the corresponding inner roller. The air inlet and air outlet ends of the first hot air unit and the air inlet and air outlet ends of the second hot air unit can be switched.

[0012] By adopting the above technical scheme, the air inlet end and the air outlet end of the first hot air unit and the second hot air unit can be switched, so that the first hot air unit and the second hot air unit can both blow air into the inner roller and absorb air from the inner roller. The drying roller is provided with an arc filter box and an inner filter box with inner air holes on half of its side. In this way, when drying textiles made of plush material, the inner roller can be rotated to a state where the half side provided with the inner air holes is covered by the arc filter box, and then the first hot air unit or the second hot air unit absorbs air from the inner roller, so that the fluff shed from the textiles made of plush material can be sucked into the arc filter box, so as to avoid the fluff flying around in the box and being entangled on the transmission structure in the box and affecting the operation of the equipment. During the drying process, the inner roller is rotated to a state where the half side provided with the inner air holes is facing away from the corresponding arc filter box, and then hot air is blown out to dry the textiles. The blown gas is not directly blown onto the arc filter box, so as to avoid blowing out the fluff accumulated in the arc filter box.

[0013] Furthermore, the half sides of the two inner rollers with inner air holes are oriented in the same direction, and the box body is provided with a synchronization mechanism for making the first drying roller and the second drying roller rotate synchronously. The synchronization mechanism can drive the two inner rollers to rotate synchronously and intermittently with an amplitude of half a circle each time, so that the half sides of the two inner rollers with inner air holes are paused towards the left rear at the same time or towards the right rear at the same time. The first hot air unit blows air into the corresponding inner roller when the half side of the inner roller with inner air holes is facing left, and sucks air from the corresponding inner roller when the half side of the inner roller with inner air holes is facing right. The second hot air unit sucks air from the corresponding inner roller when the half side of the inner roller with inner air holes is facing left, and blows air into the corresponding inner roller when the half side of the inner roller with inner air holes is facing right.

[0014] By adopting the above technical scheme, when drying textiles made of plush material, one of the first drying roller and the second drying roller blows air from the inside to the outside to dry the textile, and the other one sucks air from the outside to the inside to suck the blown-off fluff into the arc-shaped filter box. While blowing hot air to the textile to dry the textile, the blown-off floating fluff is collected, which can better collect the fluff.

[0015] Furthermore, sealing plates that can elastically move up and down are provided on the upper and lower sides of the arc filter box, and a slide groove group is provided on the inner roller, and the slide groove group includes two arc slide grooves arranged at intervals in the front and rear directions, the arc slide groove is annular, and extends along the circumference of the inner roller, and a top block is provided in each of the two arc slide grooves, and the top blocks in the two arc slide grooves are arranged opposite to each other on both sides of the central axis of the inner roller, and the half side of the inner roller with the inner air hole is located on the same side of the top blocks in the two arc slide grooves, and an insert block is provided on the side of the sealing plate close to the inner roller, and the insert blocks on the two sealing plates are respectively slidably inserted in the two arc slide grooves in the slide groove group. When the inner roller rotates until the half side with the inner air hole is covered by the corresponding arc filter box, the two top blocks respectively contact with the two insert blocks and push the insert blocks to move back to the inner roller, so that the sealing plate blocks the gap between the arc filter plate and the corresponding drying roller.

[0016] By adopting the above technical scheme, when the inner roller rotates until the half side on which the inner air hole is provided is covered by the arc filter box, the top block pushes the sealing plate so that the sealing plate blocks the gap between the arc filter box and the corresponding drying roller. In this way, when the drying roller sucks air from the outside to the inside, since the gap between the arc filter box and the drying roller is blocked, the fluff will only be sucked into the arc filter box, and will not float from the gap to the area between the drying roller and the inner roller where no arc filter box is provided, thereby avoiding the accumulation of a large amount of fluff in the area outside the arc filter box in the drying roller and blowing the fluff out again during the outward blowing process.

[0017] Furthermore, the arc filter box includes an outer arc plate and an inner arc plate which are parallel to each other, the outer arc plate is provided with a plurality of outer filter holes, the inner arc plate is provided with a plurality of inner filter holes, and the aperture size of the outer filter holes is larger than the aperture size of the inner filter holes.

[0018] Furthermore, a front-to-back extending finishing comb is provided between the first guide roller and the first drying roller and between the second guide roller and the second drying roller. The finishing comb comprises a front-to-back extending comb rod and two rows of comb teeth respectively connected to the upper and lower sides of the comb rod.

[0019] By adopting the above technical solution, during the process of drying the plush textiles, the plush textiles can be brushed by the comb teeth on the finishing roller when passing between the finishing comb and the guide roller or the drying roller, and the brushed textiles will become more fluffy after drying.

[0020] Furthermore, the finishing comb is rotatably mounted on the box body around a rotation axis extending forward and backward.

[0021] By adopting the above technical solution, the interval between the finishing comb and the corresponding drying roller and guide roller can be adjusted by rotating the finishing comb, so that the device can transport and dry textiles of different thicknesses.

[0022] Furthermore, the first hot air unit includes a first fan and a first heating wire arranged at the air inlet or air outlet of the first fan, and the second hot air unit includes a second fan and a second heating wire arranged at the air inlet or air outlet of the second fan.

[0023] The beneficial effects of a textile drying device provided by the present invention are: fewer fans are required and the equipment cost is lower. Almost all of the hot air blown out from the drying roller is blown onto the textile to dry the textile, resulting in less heat loss. During the movement of the textile, the time the textile keeps in contact with the drying roller is shorter, resulting in less mechanical damage. The textile does not have to be in a strong high-temperature drying state all the time, which can effectively prevent thermal damage to the textile. It can dry plush textiles, and in the process of drying plush textiles, the shed hair can be sucked into the arc filter box to prevent the hair from flying around. BRIEF DESCRIPTION OF THE DRAWINGS

The second rotating driving member is connected to the second comb rod to drive the second finishing comb 17 to rotate, so that the distance between the two rows of second comb teeth and the second drying roller 9 and the second guide roller 7 can be adjusted synchronously, so that the device can dry textiles 3 of different thicknesses.

[0069] The first hot air unit includes a first fan and a first electric heating wire arranged at the air inlet end of the first fan, and the second hot air unit includes a second fan and a second electric heating wire arranged at the air inlet end of the second fan. The first chamber 103 is provided with an installation shell 18, and the first fan, the second fan, the first electric heating wire, and the second electric heating wire are all installed in the installation shell 18. The air outlet end of the first fan is connected to the first air duct 20, and the first air duct 20 is connected to the inner cavity of the first inner roller 11. The air outlet end of the second fan is connected to the second air duct 19, and the second air duct 19 is connected to the inner cavity of the second inner roller 10. The first fan and the second fan are both bidirectional fans, and the air inlet end and the air outlet end of the first fan and the second fan can be switched.

[0070] The synchronous mechanism includes a synchronous belt 23 and a stepper motor, both of which are located in the second chamber 105. The synchronous belt 23 is mounted on the outside of the first inner layer roller 11 and the second inner layer roller 10 that extend into the second chamber 105. The stepper motor is connected to the first inner layer roller 11 to drive the first inner layer roller 11 to rotate. The first inner layer roller 11 rotates intermittently 180 degrees under the drive of the stepper motor. When the first inner layer roller 11 rotates, the second inner layer roller 10 is driven to rotate synchronously through the synchronous belt 23.

[0071] When the present invention is used, the textile to be dried 3 is Figure 3 The textile 3 is wound in the state of the drying chamber 104 from left to right under the traction of the driving roller group arranged outside the box body 1 and is dried. During the drying process, the first fan and the second fan are started, and the first fan is firstly made to suck air from the inside of the first inner roller 11 through the first air duct 20, and the second fan is made to blow air to the inside of the second inner roller 10 through the second air duct 19. At this time, the half side of the first inner roller 11 provided with the first inner air hole 111 and the half side of the second inner roller 10 provided with the second inner air hole are both facing right, and the hot air blown out of the second inner roller 10 passes through the second vents 902 on the second drying roller 9 and blows onto the textile 3 wound on the second drying roller 9, and also blows onto the textile 3 located on the left side of the second drying roller 9, so as to dry the textile 3, and the first drying roller 8 sucks air from the outside to the inside, and sucks the fluff blown off the textile 3 into the first arc filter box 12.

[0072] Afterwards, the first inner roller 11 and the second inner roller 10 are driven by the stepper motor to rotate to a state where the half side of the first inner roller 11 with the first inner air hole 111 and the half side of the second inner roller 10 with the second inner air hole are both facing left. At this time, the state of the first fan and the second fan are also switched. The first fan blows air into the first inner roller 11 through the first air duct 20, and the second fan sucks air from the second inner roller 10 through the second air duct 19. At this time, the first drying roller 8 blows hot air outward to dry the textile 3, and the second drying roller 9 sucks the blown-off fluff. This cycle keeps the first drying roller 8 and the second drying roller 9 in a state where one blows air and the other sucks air, so that the fluff dropped from the plush textile 3 during the drying process is always in a collected state to avoid the fluff flying around. At the same time, the time for the textile 3 to be directly in contact with the drying roller for strong drying is shortened to avoid high-temperature damage to the textile 3.

[0073] The present invention requires fewer fans when drying the textile 3, and the equipment cost is lower. During the drying process, hot air is blown out from the inside of the drying roller to dry the textile 3, and the heat loss is lower. The mechanical damage to the textile 3 during the movement is less. At the same time, the present invention is suitable for drying textiles 3 of plush materials with different thicknesses and sizes. The fluff blown off during the drying process can be collected in time and will not fly around.

[0074] In this embodiment, the first inner roller 11 and the first arc filter box 12 are installed inside the first drying roller 8, and the second inner roller 10 and the second arc filter box 13 are installed inside the second drying roller 9.
