Description

Technical Field

[0001] This application relates to the field of fabric processing, and in particular to a drying apparatus for fabric printing and dyeing. Background Technology

[0002] The dewatering and washing integrated machine is a fully automatic filtration centrifuge. After the slurry enters the filter through the feed inlet, the liquid phase is discharged from the drum under the action of centrifugal force through the filter medium and the perforated drum wall. The solid particles are trapped on the filter medium to form a filter cake layer, which is discharged from the drum under the push of the screw. The entire feeding, separation, liquid discharge, and material discharge process is completed automatically and continuously.

[0003] The utility model patent with publication number CN218020773U discloses a drying device for a rotary screen printing machine, including a drying oven body. The drying oven body has an inlet and an outlet at both ends along its length. Several horizontal transport rollers distributed along the length of the drying oven body are rotatably installed inside the drying oven body. The transport rollers are perpendicular to the length of the drying oven body. Several lifting rollers are provided inside the drying oven body through a lifting mechanism. The lifting rollers are distributed along the length of the drying oven body and are parallel to the transport rollers.

[0004] When drying fabrics, the distance the fabric moves within the drying oven is basically fixed. However, different fabrics require different drying times due to their different properties and the amount of pigment used. For fabrics that require a shorter drying time, the drying time is too long, which can easily lead to energy waste. Utility Model Content

[0005] In order to dry different fabrics for corresponding durations and reduce energy consumption, this application provides a fabric printing and dyeing drying device.

[0006] The fabric printing and dyeing drying device provided in this application adopts the following technical solution: A fabric printing and dyeing drying device includes a drying chamber. The drying chamber has fabric inlets and multiple fabric outlets at both ends along the fabric conveying direction. The multiple fabric outlets are evenly distributed vertically on the side walls of the drying chamber. Multiple horizontal tension rollers are rotatably connected inside the drying chamber. The tension rollers are arranged perpendicular to the fabric conveying direction. The multiple tension rollers are divided into two groups. Each group of tension rollers is evenly distributed vertically inside the drying chamber. One group of tension rollers is located on the fabric inlet side, and the other group of tension rollers is located on the fabric outlet side. The two groups of tension rollers are staggered vertically. The multiple fabric outlets correspond one-to-one with the multiple tension rollers near the fabric outlet side and are arranged at the same height.

[0007] By adopting the above technical solution, the fabric to be dried enters the drying chamber through the fabric inlet and passes over two sets of tension rollers in sequence, thereby extending the path length of the fabric in the drying chamber. Depending on the properties of the fabric and the amount of pigment, the fabric is removed from the appropriate fabric outlet. This allows the fabric to achieve a better drying effect in the drying chamber while shortening the residence time of the fabric in the drying chamber, thereby reducing the energy consumed when drying the fabric.

[0008] Optionally, each of the fabric outlets is provided with a sealing door for closing the fabric outlet.

[0009] When the drying oven is in operation, multiple open fabric outlets can easily cause heat loss inside the oven, reducing the drying effect. By adopting the above technical solution, unused fabric outlets can be closed with sealed doors to reduce heat loss and maintain the drying effect.

[0010] Optionally, vertical support blocks are provided at both ends of the fabric outlet in the horizontal direction, and vertical sliding grooves are provided at the ends of the two support blocks that are close to each other. The two ends of the closed door in the length direction are respectively slidably connected in the sliding grooves in the vertical direction, and the two ends of the closed door in the length direction are provided with fasteners for fixing the closed door to the support blocks.

[0011] By adopting the above technical solution, when the fabric outlet needs to be opened, the operator moves the closing door vertically upward along the length of the sliding groove and fixes it with fasteners, so that the closing door no longer closes the fabric outlet. When the fabric outlet needs to be closed, the operator moves the closing door vertically downward along the length of the sliding groove and fixes it with fasteners, so that the closing door closes the fabric outlet. The opening and closing of the fabric outlet is controlled by sliding the closing door, which is relatively convenient to operate.

[0012] Optionally, the lower end of the sliding groove is provided with a blocking block to reduce the sliding of the closed door out of the sliding groove.

[0013] By adopting the above technical solution, when the closed door moves downward along the sliding groove, the lower end of the closed door is locked in place with the obstruction, thereby reducing the occurrence of the closed door sliding out of the sliding groove.

[0014] Optionally, the fixing component includes a fixing block and a fixing spring. The bottom of the sliding groove has a first locking hole that penetrates the support block in a horizontal direction. The axial direction of the first locking hole is parallel to the length direction of the drying oven's closed door. Second locking holes are provided at both ends of the closed door in the length direction. The fixing block is slidably connected to the second locking hole along the length direction of the closed door. The fixing spring is disposed in the second locking hole in a horizontal direction. One end of the fixing spring is connected to the bottom of the second locking hole, and the other end of the fixing spring is connected to the end of the fixing block facing the second locking hole.

[0015] By adopting the above technical solution, when opening the fabric outlet, the operator moves the closing door upward so that the second locking hole on the closing door aligns with the first locking hole at the bottom of the sliding groove. The fixing spring pushes the fixing block into the first locking hole, and the fixing block simultaneously engages with both the first and second locking holes to fix the position of the closing door and maintain the open state of the fabric outlet. When closing the fabric outlet, the operator pushes the fixing block in the first locking hole into the second locking hole and moves the closing door downward so that the closing door closes the fabric outlet.

[0016] Optionally, four vertically arranged sliding rods are slidably connected to the inner wall of the drying chamber along the horizontal direction. The four sliding rods are arranged in pairs, and each pair of sliding rods is located at both ends of the length direction of each tension roller. Multiple connecting blocks are provided on the sliding rods, and the multiple connecting blocks are evenly distributed along the length direction of the sliding rods. Both ends of the tension rollers are rotatably connected to the connecting blocks. The sliding rods are connected to cylinders for driving the sliding rods to move horizontally, and the cylinders are located on the inner wall of the drying chamber.

[0017] Different fabrics have different properties and require different degrees of tension during drying. By adopting the above technical solution, the cylinder drives the sliding rod to move horizontally, the sliding rod drives the connecting block to move, and the connecting block drives the tension roller to move horizontally, thereby changing the tension of the tension roller on the fabric and making the fabric more appropriately tensioned.

[0018] Optionally, the cylinder is located on the inner bottom wall of the drying chamber and is arranged vertically upward. The upper end of the piston rod of the cylinder is coaxially connected to a drive rod. Multiple transmission rods are rotatably connected to the drive rod. The multiple transmission rods are evenly distributed along the length direction of the drive rod. The ends of the multiple transmission rods away from the drive rod are rotatably connected to a sliding rod. The length of the transmission rod is greater than the horizontal distance between the drive rod and the sliding rod. The multiple transmission rods are arranged parallel to each other.

[0019] Directly pushing the sliding rod with a cylinder can easily cause it to tilt. By adopting the above technical solution, the cylinder drives the active rod to move up and down, which in turn drives the transmission rod to move up and down, changing the tilt angle of the transmission rod relative to the horizontal plane. The transmission rod then pulls the sliding rod to move horizontally. The arrangement of multiple transmission rods can reduce the tilt of the sliding rod, making the tension of the fabric more even among all the tensioning rollers.

[0020] Optionally, a pressure sensor is provided on the roller surface of the tensioning roller. The pressure sensor is electrically connected to a controller. The pressure sensor is used to detect the pressure of the fabric on the tensioning roller and send the pressure value to the controller. The controller is electrically connected to a cylinder and controls the cylinder to stop working when the pressure value is greater than a set value.

[0021] By adopting the above technical solution, when the cylinder drives the tension roller to tighten the fabric, the fabric will squeeze the pressure sensor. The pressure sensor sends the pressure of the fabric on the tension roller to the controller. When the pressure value is greater than the set value, the controller controls the cylinder to stop working, so that the tension of the tension roller on the fabric is limited to a certain range, thus protecting the fabric.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Select a suitable fabric outlet height based on the fabric properties and the amount of dye used. This will allow the fabric to stay in the drying chamber for a shorter time during thorough drying, thereby increasing efficiency and saving energy. 2. The cylinder drives the sliding rod to move through the transmission of the drive rod and multiple transmission rods, which can reduce the tilt of the sliding rod and make the tension of the fabric more even among the multiple tension rollers; 3. Multiple fabric outlets are equipped with sealing doors, which can be closed when the drying device is working to reduce heat loss. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a drying apparatus for fabric printing and dyeing. (Refer to...) Figure 1 A fabric printing and dyeing drying device includes a drying box 1.

[0031] Reference Figure 1 as well as Figure 2 The drying chamber 1 has a fabric inlet 14 at one end and multiple fabric outlets 15 at the other end opposite to the fabric inlet 14. The multiple fabric outlets 15 are evenly distributed vertically on the side wall of the drying chamber 1.

[0032] Reference Figure 2 as well as Figure 3 Four sliding rods 11 are slidably connected inside the drying chamber 1 along the fabric conveying direction. The four sliding rods 11 are located at the four corners of the drying chamber 1. Each sliding rod 11 is fixedly connected to multiple connecting blocks 34. The multiple connecting blocks 34 are evenly distributed along the length of the sliding rod 11. The connecting blocks 34 on the two sliding rods 11 on the fabric outlet 15 side correspond one-to-one and are set at the same height. The connecting blocks 34 on the two sliding rods 11 on the fabric inlet 14 side correspond one-to-one and are set at the same height. The connecting blocks 34 on the two sliding rods 11 on the fabric outlet 15 side and the connecting blocks 34 on the two sliding rods 11 on the fabric inlet 14 side correspond one-to-one and are staggered. A horizontal tension roller 12 is rotatably connected between the two connecting blocks 34 of the same height on the two sliding rods 11 on the fabric inlet 14 side and the two sliding rods 11 on the fabric outlet 15 side. The two ends of the tension roller 12 are rotatably connected to the connecting blocks 34 respectively.

[0033] Reference Figure 2 as well as Figure 3 Four vertically upward-mounted cylinders 31 are fixed on the inner bottom wall of the drying box 1. The four cylinders 31 correspond one-to-one with four sliding rods 11. The four cylinders 31 are arranged in pairs and located on both sides of the fabric conveying direction. The upper end of the piston rod of the cylinder 31 is coaxially provided with a vertical active rod 32. The end of the active rod 32 near the corresponding sliding rod 11 is rotatably connected to multiple transmission rods 33. The multiple transmission rods 33 are evenly distributed along the vertical direction of the active rod 32. The multiple transmission rods 33 correspond one-to-one with multiple connecting blocks 34 and are rotatably connected to the corresponding connecting blocks 34.

[0034] Reference Figure 2 as well as Figure 4 At both ends of the fabric outlet 15 in the horizontal direction, there are vertical support blocks 22. The two support blocks 22 are provided with vertical sliding grooves 221 on the side that is close to each other. A blocking block 223 is fixed at the lower end of the sliding groove 221. A closing door 21 is slidably connected between the two support blocks 22 in the vertical direction. The two ends of the closing door 21 in the horizontal direction are respectively slidably connected in the sliding groove 221.

[0035] Reference Figure 4 as well as Figure 5 Both ends of the closed door 21 along its length are provided with fixing members 211 for fixing the closed door 21 to the support block 22. The fixing member 211 includes a fixing block 2111 and a fixing spring 2112. Both ends of the closed door 21 along its length are provided with second locking holes 212. The fixing block 2111 slides along the length of the closed door 21 and is connected to the second locking hole 212. The fixing spring 2112 is horizontally disposed in the second locking hole 212, with one end of the fixing spring 2112 touching the bottom of the second locking hole 212. The other end of the fixing spring 2112 is connected to the end of the fixing block 2111 facing the second locking hole 212. The fixing spring 2112 is used to maintain the state in which the fixing block 2111 is partially exposed in the second locking hole 212. The bottom of the sliding groove 221 is provided with a first locking hole 222 coaxial with the second locking hole 212. The first locking hole 222 passes through the support block 22 in the direction away from the closed door 21. When the fixing block 2111 is partially inserted into the first locking hole 222, the fixing block 2111 fixes the position of the closed door 21.

[0036] The implementation principle of a fabric printing and dyeing drying device according to an embodiment of this application is as follows: When drying the fabric, the fabric enters the drying chamber 1 through the fabric inlet 14 and passes over the two sets of tension rollers 12 in sequence, thereby extending the path length of the fabric in the drying chamber body. According to the properties of the fabric and the amount of pigment, the fabric is taken out from the appropriate position of the fabric outlet 15, so that the fabric can obtain a better drying effect in the drying chamber 1 while shortening the residence time of the fabric in the drying chamber 1, thereby reducing the energy consumed when drying the fabric.

[0037] When the fabric outlet 15 is opened, the operator moves the closing door 21 upward so that the second locking hole 212 on the closing door 21 aligns with the first locking hole 222 at the bottom of the sliding groove 221. The fixing spring 2112 pushes the fixing block 2111 into the first locking hole 222. The fixing block 2111 is simultaneously locked with the first locking hole 222 and the second locking hole 212, thus fixing the position of the closing door 21 and maintaining the open state of the fabric outlet 15. When the fabric outlet 15 is closed, the operator pushes the fixing block 2111 in the first locking hole 222 into the second locking hole 212 and moves the closing door 21 downward so that the closing door 21 closes the fabric outlet 15.

[0038] When the fabric inside the drying chamber 1 is stretched, the cylinder 31 drives the active rod 32 to move up and down, and the active rod 32 drives the transmission rod 33 to move up and down, causing the inclination angle of the transmission rod 33 with the horizontal plane to change. The transmission rod 33 pulls the sliding rod 11 to move in the horizontal direction. The arrangement of multiple transmission rods 33 can reduce the inclination of the sliding rod 11, so that the tension of all tensioning rollers 12 on the fabric is more balanced. When the tensioning rollers 12 stretch the fabric, the fabric will squeeze the pressure sensor 13 on the tensioning rollers 12. The pressure sensor 13 sends the pressure of the fabric on the tensioning rollers 12 to the controller 4. When the pressure value is greater than the set value, the controller 4 controls the cylinder 31 to stop working, so that the tension of the tensioning rollers 12 on the fabric is limited to a certain range, which plays a role in protecting the fabric.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
