[0013] In a preferred embodiment of the present invention, the cylindrical fabric drying and opening device further includes:

[0014] The circulation pipe is connected at both ends to the sealed chamber and the high-temperature chamber in the drying device, respectively. The gas entering the circulation pipe through the sealed chamber undergoes cooling and condensation and heat exchange and heating in sequence before entering the high-temperature chamber to dry the cylindrical cloth.

[0015] In a preferred embodiment of the present invention, the circulation pipeline is provided with a condensation heat exchanger for cooling and condensing the gas to collect the dyeing medium in the gas.

[0021] In a preferred embodiment of the present invention, the control box is electrically connected to the box door at the fabric inlet to control the opening and closing of the box door.

[0022] In a preferred embodiment of the present invention, the flow direction of the gas in the high-temperature chamber is opposite to the conveying direction of the outer cylindrical cloth of the drying sleeve.

After the cylindrical fabric is dried by the drying device, it is opened by the opening device, thereby realizing the integrated design of drying and opening.

[0025] 2. The cylindrical fabric drying and opening equipment of the present invention has a circulation pipe connected to the box body. The dyeing medium contained in the gas in the sealed chamber is recovered through the circulation pipe. When the cylindrical fabric drying and opening equipment is running, the gas in the box body is first extracted into the circulation pipe. Then, the gas in the circulation pipe is cooled by heat exchange. The dyeing medium is condensed and liquefied into droplets and recycled, avoiding waste of the dyeing medium. Then, the gas is heated. The gas that has been heated by heat exchange enters the drying device in the box body to dry the cylindrical fabric.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figure 1 As shown, the present invention provides a cylindrical fabric drying and opening device, which includes: a housing 10, the housing having a sealed chamber 13 inside, the housing 10 having a fabric inlet 11 and a fabric outlet 12; a drying device located in the sealed chamber 13 for drying the cylindrical fabric, the drying device having a drying sleeve 20, the drying sleeve 20 having a high-temperature chamber 21 inside, the cylindrical fabric input through the fabric inlet 11 being sleeved on the drying sleeve 20, and output from the fabric outlet 12 after being dried by the drying sleeve 20; and an opening device 50 disposed at the cylindrical fabric output end of the drying sleeve 20.

[0044] The cylindrical fabric drying and opening device of the present invention has a drying device and an opening device 50 installed in the sealed chamber 13 of the housing 10. After the cylindrical fabric is dried by the drying device, it is opened by the opening device 50, thereby realizing the integrated design of drying and opening.

[0045] Specifically, such as Figure 1 As shown, the housing 10 serves as the outer shell of the cylindrical fabric drying and opening device, and its interior forms a relatively closed sealed chamber 13. In this embodiment, the housing 10 has a cubic structure, and the sealed chamber 13 is also a cubic accommodating space. The front and rear ends of the housing 10 are respectively provided with a fabric inlet 11 and a fabric outlet 12. The continuously conveyed cylindrical fabric can enter the housing 10 through the fabric inlet 11, be processed in the sealed chamber 13, and then be output from the fabric outlet 12.

[0046] A drying device is installed inside the sealed chamber 13. The drying device has a cylindrical drying sleeve 20, inside which a cylindrical high-temperature chamber 21 is formed, through which high-temperature gas flows. The cylindrical cloth entering the sealed chamber 13 through the cloth inlet 11 can be fitted onto the drying sleeve 20 for drying. The cylindrical cloth passing through the drying device is output from the sealed chamber 13 through the cloth outlet 12. The cylindrical cloth fitted onto the drying sleeve 20 can be continuously conveyed forward along the length of the drying sleeve 20.

[0047] The fabric output end of the drying sleeve 20 is equipped with a width-opening device 50, which is fixed inside the box 10 and is used to open the cylindrical fabric after it has been dried by the drying sleeve 20.

[0048] The following will further explain the structure and technical effects of some preferred embodiments of the cylindrical fabric opening drying equipment described in this invention.

[0049] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the drying sleeve 20 includes an outer cylinder 22 and an inner cylinder 23. The outer cylinder 22 is composed of a plurality of tube segments 221 spaced apart along the circumference of the drying sleeve 20. The inner cylinder 23 is fitted with a slider 24 that can move along its length. Each tube segment 221 is hinged to the slider 24 by a connecting rod 25.

[0050] Multiple tube segments 221 constituting the outer cylinder 22 are hinged to the slider 24 of the inner cylinder 23 via connecting rods 25. By pushing the slider 24 on the inner cylinder 23 to move, the radial distance between the inner cylinder 23 and the tube segments 221 is changed, thereby changing the diameter of the outer cylinder 22, thus meeting the drying and opening requirements of cylindrical fabrics of different sizes.

[0051] Specifically, the outer cylinder 22 is composed of multiple tube segments 221, each of which is a strip structure with an arc cross-section. These tube segments 221 are spaced apart along the circumference of the inner cylinder 23 on its outer side. A connecting rod 25 is hinged to the inner surface of each tube segment 221, and the other end of the connecting rod 25 is hinged to a slider 24 on the inner cylinder 23. By moving the slider 24 on the inner cylinder 23, the angle between the connecting rod 25 and the inner cylinder 23 and the tube segments 221 is changed, thereby altering the radial distance between the inner cylinder 23 and the tube segments 221. This results in a change in the diameter of the outer cylinder 22 composed of the multiple tube segments 221, enabling the drying of cylindrical fabrics with different diameters.

[0052] Preferably, a slider 24 is provided at each end of the inner cylinder 23, and each end of each tube segment 221 is hinged to the two sliders 24 by a connecting rod 25. The diameter of the outer cylinder 22 is adjusted by moving the two sliders 24 closer or further apart. Both ends of the tube segment 221 are connected and fixed by a connecting rod 25 to prevent them from tilting, which would cause the shape of the outer cylinder 22 composed of multiple tube segments 221 to deform.

[0053] Furthermore, the flow direction of the high-temperature gas in the high-temperature chamber 21 is opposite to the conveying direction of the cylindrical cloth on the outside of the drying sleeve 20, thereby improving the drying effect of the drying sleeve 20 on the cylindrical cloth.

[0054] According to one embodiment of the present invention, the side wall of the drying sleeve 20 has a plurality of air holes. The high-temperature gas in the high-temperature chamber 21 passes through the air holes and directly contacts the cylindrical cloth sleeved on the drying sleeve 20 for heat exchange, thereby improving the drying effect of the cylindrical cloth.

[0055] According to one embodiment of the present invention, such as Figure 1 As shown, at least one set of first guide rollers 40 is sleeved on the outer side of the drying sleeve 20 to guide the cylindrical fabric forward. The first guide rollers 40 is a ring structure composed of multiple guide rollers, which is sleeved on the outer side of the drying sleeve 20. The cylindrical fabric can be continuously conveyed from the cylindrical fabric input end to the cylindrical fabric output end under the drive of the first guide rollers 40. In this embodiment, multiple sets of first guide rollers 40 are sleeved at intervals on the outer side of the drying sleeve 20 along the length direction of the drying sleeve 20.

[0056] According to one embodiment of the present invention, such as Figure 1 As shown, the opening device 50 has an opening knife 51 facing the outer side wall of the drying sleeve 20. The drying device and the opening device 50 are installed in the sealed chamber 13 of the housing 10. After the cylindrical cloth is dried by the drying device, it is opened by the opening device 50, thereby realizing the integrated design of drying and opening.

[0057] In this embodiment, the opening device 50 is located above the cylindrical fabric output end of the drying sleeve 20. When conveying the cylindrical fabric, its circumferential orientation is adjusted so that the opening line on the cylindrical fabric is at the top to correspond to the opening knife 51, ensuring that the cylindrical fabric can be smoothly opened into strip fabric after passing through the opening device 50.

[0058] According to one embodiment of the present invention, such as Figure 1 As shown, the cylindrical fabric output end of the drying sleeve 20 is also provided with a second guide roller 41. The opening device 50 and the second guide roller 41 are respectively located on opposite sides of the drying sleeve 20. In this embodiment, the second guide roller 41 is located below the cylindrical fabric output end of the drying sleeve 20. The strip of fabric formed after being opened by the opening device 50 can fall onto the second guide roller 41 and continue to be conveyed forward by the second guide roller 41.

[0059] According to one embodiment of the present invention, such as Figure 1 As shown, a conveyor belt 42 is provided at the fabric outlet 12. The conveyor belt 42 is located below the second guide roller 41 and passes through the side wall of the box 10. The conveyor belt 42 is located below the second guide roller 41. The cylindrical fabric that has been dried and opened on the second guide roller 41 can fall onto the conveyor belt 42 and be output from the fabric outlet 12 of the box 10 under the conveyor belt 42. The output end of the conveyor belt 42 is located outside the box 10, and a fabric cart 43 is provided at the output end of the conveyor belt 42. The cylindrical fabric enters and is stored in the fabric cart 43 after passing through the conveyor belt 42.

[0060] According to one embodiment of the present invention, such as Figure 1As shown, the cylindrical fabric drying and opening device of the present invention also includes a circulation pipe 30, the two ends of which are connected to the sealed chamber 13 and the high-temperature chamber 21 in the drying device, respectively. The gas entering the circulation pipe 30 through the sealed chamber 13 passes through the cooling and condensation and heat exchange and heating in sequence before entering the high-temperature chamber 21 to dry the cylindrical fabric.

[0061] A circulation pipe 30 is connected to the housing 10, through which the dyeing medium contained in the gas in the sealed chamber 13 is recovered. During operation, the cylindrical fabric drying and opening equipment first draws the gas from the housing 10 into the circulation pipe 30, then cools the gas through heat exchange, causing the dyeing medium to condense and liquefy into droplets. These droplets are collected for recycling, avoiding waste. The gas is then heated, and the heated gas re-enters the drying device within the housing 10 to dry the cylindrical fabric. This creates a gas circulation loop between the housing 10, the circulation pipe 30, and the drying device, achieving efficient drying and opening of the cylindrical fabric while simultaneously recovering the dyeing medium from the gas.

[0062] Specifically, one end of the circulation pipe 30 is connected to the sealed chamber 13, and the other end is connected to the high-temperature chamber 21 inside the drying sleeve 20. In this embodiment, the circulation pipe 30 is located outside the box body 10, with one end located on the side wall of the box body 10 and connected to the sealed chamber 13 inside the box body 10, and the other end passing through the side wall of the box body 10 and connected to the drying device inside the sealed chamber 13. High-temperature gas flows from the cylindrical cloth output end of the drying sleeve 20 into the high-temperature chamber 21 and flows towards the cylindrical cloth input end of the drying sleeve 20.

[0063] In other embodiments of the present invention, the circulation pipe 30 may also be arranged inside the box 10. In this case, the two ends of the circulation pipe 30 do not need to be inserted through the side wall of the box 10. One end is directly connected to the sealed chamber 13 as a free end, and the other end is directly connected to the drying device.

[0064] The gas entering the circulation pipe 30 will undergo two processes: cooling and heating. During the cooling process, the dyeing medium mixed in the gas will liquefy and remain, making it convenient to recycle and reuse the dyeing medium. During the heating process, the gas will be heated or heated by heat exchange for use by the gas drying device. Accordingly, since the drying device described in this invention is connected to the circulation pipe 30, it dries the fabric cylinder using high-temperature gas.

[0065] According to one embodiment of the present invention, such as Figure 1As shown, a condensing heat exchanger 31 is provided on the circulation pipe 30 for cooling and condensing the gas to collect the dyeing medium in the gas. The condensing heat exchanger 31 can realize the process of cooling the gas in the circulation pipe 30 and collect the condensed dyeing medium droplets, thereby avoiding the waste of dyeing medium.

[0066] According to one embodiment of the present invention, such as Figure 1 As shown, a heat exchanger 32 for heating the gas is provided on the circulation pipe 30 between the condenser heat exchanger 31 and the drying device. The heat exchanger 32 enables the gas in the circulation pipe 30 to be heated by heat exchange; in other embodiments of the present invention, the gas in the circulation pipe 30 can also be heated by direct heating.

[0067] According to one embodiment of the present invention, such as Figure 1 As shown, a fan 33 is provided on the circulation pipe 30. The fan 33 can provide power for the flow of gas in the circulation pipe 30; in this embodiment, the fan 33 is located between the condenser heat exchanger 31 and the heat exchanger 32.

[0068] According to one embodiment of the present invention, such as Figure 1 As shown, a temperature and humidity meter 60 is installed inside the housing 10. In this embodiment, the temperature and humidity meter 60 is installed at the inlet end of the circulation pipe 30; a liquid level gauge 61 is installed at the bottom of the housing 10. The temperature and humidity meter 60 is used to monitor the temperature and humidity of the gas at the inlet end of the circulation pipe 30; the liquid level gauge 61 is used to monitor the liquid level inside the housing 10.

[0069] Furthermore, the cylindrical fabric drying and opening equipment also includes a control box 70, which is electrically connected to a temperature and humidity meter 60 and a drying device. A level gauge 61 and a drain valve 14 located at the bottom of the box 10 are electrically connected to the control box 70.

[0070] The control box 70 can adjust the operating speed of the drying device according to the temperature and humidity of the gas in the circulation pipe 30 monitored by the thermometer and hygrometer 60, so as to ensure the drying effect of the cylindrical cloth. At the same time, the control box 70 can also control the opening and closing of the drain valve 14 according to the liquid level height in the box 10 monitored by the liquid level gauge 61. The automatic control of the equipment is realized through the control box 70 and various sensors, and the operation is relatively simple.

[0071] During actual operation, if the temperature and humidity of the gas at the inlet of the circulation pipe 30 are low and high, it indicates that there is a lot of dyeing medium remaining on the cylindrical fabric. In this case, the control box 70 controls the rotation speed of the first guide roller group 40 on the drying device to decrease, thereby reducing the conveying speed of the cylindrical fabric on the drying sleeve 20 and improving the drying effect of the cylindrical fabric. If the temperature and humidity of the gas at the inlet of the circulation pipe 30 are high and low, it indicates that there is little dyeing medium remaining on the cylindrical fabric. In this case, the control box 70 controls the rotation speed of the first guide roller group 40 on the drying device to increase, thereby increasing the conveying speed of the cylindrical fabric on the drying sleeve 20 and maximizing the efficiency of the drying operation while ensuring the drying effect of the cylindrical fabric. If the level gauge 61 detects that the liquid level in the tank 10 has risen to a predetermined threshold, the control box 70 controls the drain valve 14 to open and discharge the liquid in the tank 10.

[0072] According to one embodiment of the present invention, such as Figure 1 As shown, the control box 70 is electrically connected to the door 15 at the fabric inlet 11 to control the opening and closing of the door 15. The fabric inlet 11 of the box body 10 is provided with a door 15, and the opening and closing of the door 15 is controlled by the control box 70.

[0073] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
