Description

Technical Field

[0001] This invention belongs to the field of chemical fiber processing technology, and specifically relates to a chemical fiber production drying device. Background Technology

[0002] Chemical fiber generally refers to chemical fiber, which is a fiber with textile properties made from natural or artificially synthesized polymer compounds as raw materials through processes such as preparing spinning solution, spinning, and subsequent treatment. Chemical fiber can be processed into chemical fiber fabrics for making clothing. In the process of processing chemical fiber fabrics, processes such as spinning, washing, and drying are required.

[0003] In the drying of chemical fiber fabrics, the fabric is usually placed on the surface of the platform inside the drying oven, and hot air is blown onto the surface of the fabric to dry it. However, in this method, the surface of the fabric is in direct contact with the hot air, while the back of the fabric is in contact with the platform and cannot be in direct contact with the hot air. This results in different drying effects on the two sides of the fabric and uneven drying. To address this, we propose a chemical fiber production drying device. Summary of the Invention

[0004] The purpose of this invention is to provide a chemical fiber production drying device to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A chemical fiber production drying device includes a drying box, a frame, and an L-shaped switch door. The frame is disposed on the upper side of the drying box, and the surface of the drying box has an air outlet that matches the frame. The upper side of the L-shaped switch door is connected to the upper side of the frame with damping rotation. A mounting mechanism is installed inside the frame.

[0007] The erection mechanism includes two rotating shafts, two mounting plates, two connecting rods, and several fixing components. The two rotating shafts are rotatably connected to both sides of the frame, and the two mounting plates are fixedly connected to the ends of the two rotating shafts. The two ends of the two mounting plates are integrally connected and fixed by the two connecting rods. The number of fixing components is a multiple of 2 and they are grouped in pairs. Each fixing component includes a fixing block and a movable clamping block. The fixing block is installed between the two connecting rods. Each end of the fixing block has an assembly hole, and a first spring is installed inside the assembly hole. The first spring is fixedly connected to the movable clamping block.

[0008] An exhaust box is also provided on the upper side of the frame, and an exhaust pipe is fixedly connected to the exhaust box. Both of the rotating shafts extend outward through the frame. A locking mechanism is provided between the L-shaped door and the two rotating shafts, and one of the rotating shafts is provided with a driving mechanism.

[0009] The locking mechanism includes a first hinge seat, a second hinge seat, a first hydraulic cylinder, and two second hydraulic cylinders. The first hinge seat is fixedly mounted on the upper side of the L-shaped door, and the second hinge seats are fixedly mounted on the upper side of the frame. The bottom of the first hydraulic cylinder is hinged to the second hinge seat. A first piston disc is slidably connected inside the first hydraulic cylinder, and a first slide rod is fixedly connected to the first piston disc. The first slide rod slides through the first hydraulic cylinder towards the first hinge seat, and its end is hinged to the first hinge seat. The end of the first hydraulic cylinder away from the first slide rod is fixed. Two second hydraulic cylinders are mounted on the outside of the frame and on both sides of the rotating shaft, connected by hydraulic pipes. Each of the two second hydraulic cylinders has a second piston disc slidably connected inside. Each of the two second piston discs is fixedly connected to a second sliding rod, and both second sliding rods slide through the second hydraulic cylinders towards the rotating shaft. Each end of each second sliding rod is fixedly connected to an arc-shaped clamping block. A connecting pipe is installed at the end of each of the two second hydraulic cylinders away from the second sliding rod, and the two connecting pipes are connected to the hydraulic pipes. A second spring is fixedly connected between the second piston disc and the second hydraulic cylinder.

[0010] The two connecting pipes are connected to a manifold, which is connected to the hydraulic pipe. The first hydraulic cylinder, the hydraulic pipe, the manifold, the connecting pipe, and the second hydraulic cylinder are filled with hydraulic oil.

[0011] A protective shell is also installed on the outside of the frame. The drive mechanism includes a blade shaft, which is fixed to the end of the rotating shaft. The blade shaft rotates through the corresponding protective shell. Several blades are fixedly arranged on the side of the blade shaft. An exhaust shell is also provided on the outside of the protective shell. The exhaust shell consists of an arc-shaped part, an air outlet part, and an air inlet part. The air outlet part and the air inlet part are respectively connected to both sides of the arc-shaped part. The air inlet part is arranged along the tangent direction of the arc-shaped part. The arc-shaped part matches and covers the blade. The air inlet part is provided with an air inlet pipe, which is connected to the exhaust pipe.

[0012] The arc-shaped clamping block is made of rubber material, and the side of the rotating shaft is machined with several strip-shaped protrusions.

[0013] The outer wall of the frame is fixedly connected to a mounting base that matches the air inlet pipe.

[0014] Both ends of the fixing block are slidably connected to the two connecting rods respectively. The same end of the two fixing blocks in the same group is fixedly provided with a mounting platform. One of the mounting platforms is rotatably connected to a first screw, and the other mounting platform has a threaded through hole that matches the first screw. The first screw passes through the threaded through hole and is threadedly connected to the threaded through hole. A rotating handle is fixedly provided at the end of the first screw.

[0015] The L-shaped door is also equipped with a transparent viewing window.

[0016] The fixed block and the movable clamping block are each provided with a number of corresponding elastic rubber heads on the opposite side.

[0017] This invention uses a mounting mechanism to secure the synthetic fiber fabric. When the L-shaped door opens the frame, a locking mechanism automatically clamps and locks the mounting mechanism to prevent it from rotating, making it easy to hold and secure the synthetic fiber fabric. When the L-shaped door closes the frame, the locking mechanism automatically releases its lock on the mounting mechanism. After the drying chamber and exhaust box are started, the drive mechanism uses the generated airflow to drive the rotating shaft, allowing the synthetic fiber fabric to continuously rotate within the frame, thus thoroughly drying both the top and bottom surfaces of the fabric.

[0030] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Example 1, as Figures 1 to 7 The chemical fiber production drying device shown includes a drying box 100, a frame 101 and an L-shaped switch door 102. The frame 101 is disposed on the upper side of the drying box 100. An air outlet 103 matching the frame 101 is opened on the surface of the drying box 100. The upper side of the L-shaped switch door 102 is connected to the upper side of the frame 101 with damping rotation. A mounting mechanism is installed inside the frame 101.

[0032] The erection mechanism includes two rotating shafts 104, two mounting plates 105, two connecting rods 106, and several fixing components. The two rotating shafts 104 are rotatably connected to both sides of the frame 101, and the two mounting plates 105 are fixedly connected to the ends of the two rotating shafts 104. The two ends of the two mounting plates 105 are integrally connected and fixed through the two connecting rods 106. The number of fixing components is a multiple of 2 and they are grouped in pairs. Each fixing component includes a fixing block 107 and a movable clamping block 108. The fixing block 107 is installed between the two connecting rods 106. Both ends of the fixing block 107 are provided with assembly holes. A first spring 1071 is installed inside the assembly holes and is fixedly connected to the movable clamping block 108.

[0033] An exhaust box 109 is also provided on the upper side of the frame 101. An exhaust pipe 1091 is fixedly connected to the exhaust box 109. Two rotating shafts 104 extend outward through the frame 101. A locking mechanism is provided between the L-shaped switch door 102 and the two rotating shafts 104. One of the rotating shafts 104 is provided with a drive mechanism.

[0034] The locking mechanism includes a first hinge seat 110, a second hinge seat 111, a first hydraulic cylinder 112, and two second hydraulic cylinders 113. The first hinge seat 110 is fixedly mounted on the upper side of the L-shaped door 102, and the second hinge seat 111 is fixedly mounted on the upper side of the frame 101. The bottom of the first hydraulic cylinder 112 is hinged to the second hinge seat 111. A first piston disc 1121 is slidably connected inside the first hydraulic cylinder 112, and a first slide rod 1122 is fixedly connected to the first piston disc 1121. The first slide rod 1122 slides through the first hydraulic cylinder 112 towards the first hinge seat 110, and the end of the first slide rod 1122 is hinged to the first hinge seat 110. The end of the first hydraulic cylinder 112 away from the first slide rod 1122 is fixedly connected to a hydraulic cylinder. The pressure pipe 1123 and two second hydraulic cylinders 113 are installed on the outside of the frame 101 and on both sides of the rotating shaft 104. The two second hydraulic cylinders 113 are slidably connected to the inside of each second piston disc 1131. The two second piston discs 1131 are fixedly connected to the second slide rods 1132. The two second slide rods 1132 slide through the second hydraulic cylinders 113 in the direction of the rotating shaft 104. The ends of the two second slide rods 1132 are fixedly connected to the arc-shaped clamping blocks 1133. The ends of the two second hydraulic cylinders 113 away from the second slide rods 1132 are connected to the connecting pipes 1134. The two connecting pipes 1134 are connected to the hydraulic pipe 1123. The second piston discs 1131 and the second hydraulic cylinders 113 are fixedly connected to the second springs 1135.

[0035] Two connecting pipes 1134 are connected to a manifold 114, which is connected to a hydraulic pipe 1123. The first hydraulic cylinder 112, hydraulic pipe 1123, manifold 114, connecting pipe 1134 and the second hydraulic cylinder 113 are filled with hydraulic oil.

[0036] A protective shell 115 is also installed on the outside of the frame 101. The drive mechanism includes a blade shaft 116, which is fixed to the end of the rotating shaft 104. The blade shaft 116 rotates through the corresponding protective shell 115. Several blades 117 are fixedly arranged on the side of the blade shaft 116. An exhaust shell 118 is also provided on the outside of the protective shell 115. The exhaust shell 118 is composed of an arc-shaped part 1181, an air outlet part 1182, and an air inlet part 1183. The air outlet part 1182 and the air inlet part 1183 are respectively connected to both sides of the arc-shaped part 1181. The air inlet part 1183 is arranged along the tangent direction of the arc-shaped part 1181. The arc-shaped part 1181 matches and covers the blades 117. The air inlet part 1183 is provided with an air inlet pipe 1184, which is connected to the exhaust pipe 1091.

[0037] After the drying oven 100 is started, it can blow hot air into the frame 101 through the air outlet 103 to dry the chemical fiber fabric. The L-shaped door 102 is connected to the frame 101 with damping rotation, so that the L-shaped door 102 can be opened and closed without easily loosening. The two mounting plates 105 and the two connecting rods 106 constitute the mounting mechanism. The fixing block 107 of the fixing component is installed between the two connecting rods 106 and is fixed to the movable clamp 108 by the first spring 1071. The number of components is a multiple of 2 and they are grouped in pairs. Therefore, when fixing the chemical fiber fabric, the two movable clamps 108 of each fixing component can be pulled up to place the two ends of the chemical fiber fabric on the two fixing blocks 107 of each fixing component. Then, the movable clamps 108 are released. Under the elastic force of the first spring 1071, the chemical fiber fabric can be fixed by the movable clamps 108 and the fixing blocks 107 being tightly attached. The rotating shaft 104 allows the mounting mechanism to rotate inside the frame 101.

[0038] In the initial state, such as Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown:

[0039] The L-shaped door 102 flips to close the frame 101. The first hinge seat 110 pulls the first slide rod 1122, causing the first slide rod 1122 to be in an extended state. The second spring 1135 is at its normal extension length. The second piston disc 1131 is pulled to retract the second slide rod 1132, allowing the arc-shaped clamping block 1133 of the second slide rod 1132 to move away from the rotating shaft 104. At this time, the rotating shaft 104 is not clamped, and the erection mechanism can rotate. The first hydraulic cylinder 112, hydraulic pipe 1123, manifold 114, connecting pipe 1134, and the second hydraulic cylinder 113 are filled with hydraulic oil.

[0040] The following steps are included when using it:

[0041] Step ①: In the initial state, people flip the L-shaped door 102 upwards to open it. During this process, the first hinge seat 110 pushes the first slide rod 1122. The first hinge seat 110 and the second hinge seat 111 can prevent the first slide rod 1122 and the first hydraulic cylinder 112 from getting stuck during the flipping of the L-shaped door 102. The movement of the first slide rod 1122 causes the first piston disc 1121 to move and push the hydraulic oil inside the first hydraulic cylinder 112 into the hydraulic pipe 1123. It then enters the two connecting pipes 1134 through the manifold 114. Finally, the two second hydraulic cylinders 113 are filled with oil, which pushes the second piston disc 1131 and the second slide rod 1132 to slide close to the rotating shaft 104. This causes the second spring 1135 to stretch elastically and the two arc-shaped clamping blocks 1133 to clamp and fix the rotating shaft 104 from both sides. The rotating shaft 104 cannot rotate, and the erection mechanism is in a locked state.

[0042] Step 2: After the rotating shaft 104 is fixed, the mounting frame consisting of the two mounting plates 105 and the two connecting rods 106 is locked synchronously. People can then place the two ends of the chemical fiber fabric on the two fixing blocks 107 of each set of fixing components by pulling up the two movable clamps 108 of each set of fixing components. Then, release the movable clamps 108. Under the elastic force of the first spring 1071, the chemical fiber fabric can be fixed by the movable clamps 108 and the fixing blocks 107 being tightly attached.

[0043] Step 3: Flip down to close the L-shaped switch door 102. Similarly, under the elastic rebound of the second spring 1135, the hydraulic oil inside the second hydraulic cylinder 113 is discharged, so that the first hydraulic cylinder 112 is refilled with oil, and the device returns to the initial state. At this time, the rotating shaft 104 will no longer be locked and can rotate.

[0044] Step 4: Hot air is blown into the frame 101 by starting the drying box 100, and at the same time, the exhaust box 109 is started to draw in the hot air, forming an airflow within the frame 101. The airflow passes through the exhaust pipe 1091 and the inlet pipe 1184 and enters the air inlet 1183 of the exhaust shell 118. Since the air inlet 1183 is set along the tangent of the arc-shaped part 1181, the airflow will push the blades 117 inside the arc-shaped part 1181, causing the blade shaft 116 to rotate, thereby causing the rotating shaft 104 to rotate relative to the frame 101, allowing the chemical fiber fabric to rotate within the frame 101, thus thoroughly drying both the top and bottom surfaces of the chemical fiber fabric. Finally, the airflow is discharged through the outlet 1182.

[0045] In this embodiment, the erection mechanism can fix the chemical fiber fabric. When the L-shaped door 102 opens the frame 101, the locking mechanism can automatically clamp and lock the rotating shaft 104 to prevent the erection mechanism from rotating, making it easier for people to clamp and fix the chemical fiber fabric. At the same time, after the L-shaped door 102 closes the frame 101, the locking mechanism can automatically release the lock on the rotating shaft 104. After the drying box 100 and the exhaust box 109 are started, the drive mechanism can use the airflow to drive the rotating shaft 104, so that the chemical fiber fabric can be continuously turned over in the frame through the erection mechanism, thereby drying both the top and bottom sides of the chemical fiber fabric.

[0046] As a further optimization of this embodiment, such as Figure 5 As shown, the arc-shaped clamping block 1133 is made of rubber material, and the side of the rotating shaft 104 is machined with several strip-shaped protrusions 1041.

[0047] The side of the rotating shaft 104 is machined with strip-shaped protrusions 104. When the arc-shaped clamping block 1133 clamps the shaft, the arc-shaped clamping block 1133 is made of rubber material and has elasticity. Therefore, it can cooperate with the strip-shaped protrusions 104 during clamping, thereby preventing the rotating shaft 104 from rotating and achieving a better clamping and locking effect.

[0048] As a further optimization of this embodiment, such as Figure 6 As shown, a mounting base 119 matching the air inlet pipe 1184 is fixedly connected to the outer wall of the frame 101.

[0049] The air inlet pipe 1184 can be fixed by the mounting bracket 119, thereby ensuring the stability of the air inlet pipe 1184 installation.

[0050] Example 2 is a further functional improvement based on Example 1, such as... Figure 8 As shown, the two ends of the fixing block 107 are slidably connected to the two connecting rods 106 respectively. The two fixing blocks 107 in the same group are fixedly provided with mounting platforms 200 at the same end. One mounting platform 200 is rotatably connected to the first screw 201, and the other mounting platform 200 has a threaded through hole that matches the first screw 201. The first screw 201 passes through the threaded through hole and is threadedly connected to the threaded through hole. A rotating handle 202 is fixedly provided at the end of the first screw 201.

[0051] By operating the rotating handle 202, the first screw 201 is rotated, thereby adjusting the distance between the two mounting platforms 200. This allows for adjustment of the distance between the fixing blocks 107 of each set of fixing components, enabling corresponding adjustments for different lengths of chemical fiber fabrics and making the device more versatile.

[0052] As a further optimization of this embodiment, such as Figure 8As shown, the L-shaped door 102 is also equipped with a transparent viewing window 203.

[0053] The transparent window 203 allows people to easily view the drying progress of synthetic fiber fabrics.

[0054] As a further optimization of this embodiment, the fixed block 107 and the movable clamping block 108 are each provided with a plurality of corresponding elastic rubber heads (not shown in the figure) on the opposite side.

[0055] Under the elastic action of the first spring 1071, the fixed block 107 and the movable clamping block 108 can clamp the chemical fiber fabric with their elastic rubber heads. The clamping contact area is small, which is beneficial for drying.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
