Description

Technical Field

[0001] The present application relates to the field of drying equipment, and in particular to a chemical fiber drying device. Background Art

[0002] Chemical fiber drying devices are widely used in the textile industry to effectively remove moisture from the surface of chemical fibers, thereby improving product quality and processing efficiency. With the rapid development of the chemical fiber industry, efficient drying equipment has become one of the key factors in ensuring production continuity and finished product quality. Traditional chemical fiber drying technology mainly relies on a combination of heating and ventilation to achieve rapid dehydration while ensuring fiber performance, which is of great significance to improving corporate competitiveness.

[0003] At present, in order to extend the residence time of chemical fibers in the drying box to fully remove moisture, the industry generally uses multiple transmission rollers to guide the transmission path of the chemical fibers inside the drying box, allowing the chemical fibers to bend repeatedly inside the drying box for transmission.

[0004] However, before drying the chemical fiber, the workers need to put the chemical fiber into the drying box. In the process of putting the chemical fiber into the drying box, the chemical fiber needs to repeatedly bypass the transmission roller, and each time it passes the transmission roller, additional treatment is required to prevent the chemical fiber from piling up and folding, which seriously affects the overall operation efficiency.

[0007] By adopting the above technical solution, before the staff puts the chemical fiber into the box, the chemical fiber is first flattened, and then the chemical fiber is put into the wire body from the feed port, and then the chemical fiber is moved out of the box in a straight line. After the chemical fiber is moved out of the box's discharge port, the first driving mechanism drives the first lifting assembly and the second lifting assembly to move in the opposite direction, the first lifting assembly drives the first transmission roller to squeeze the chemical fiber from top to bottom, and the second lifting assembly drives the second transmission roller to squeeze the chemical fiber from bottom to top, so that the chemical fiber is bent to extend the transmission path.

The second lifting plate is connected to each second mounting seat through the second connecting rod, so that each second transmission roller can be lifted and lowered when the second lifting assembly is lifted and lowered.

[0010] Optionally, both the first lifting plate and the second lifting plate are fixedly mounted with a pull rope, the pull rope slides upward through the top side of the box body and is fixedly mounted with a counterweight block.

[0011] By adopting the above technical solution, the counterweight block offsets part of the weight of the first lifting plate and the second lifting plate, thereby facilitating the first driving mechanism to drive the first lifting plate and the second lifting plate to move up and down.

[0012] Optionally, the first driving mechanism includes a push rod, a first driving rod, a second driving rod and a locking assembly, one end of the first driving rod is hinged to the rod body of the push rod, the other end of the first driving rod is hinged to the first lifting assembly, one end of the second driving rod is hinged to the rod body of the push rod, the other end of the second driving rod is hinged to the second lifting assembly, both ends of the box body are provided with through holes for the push rod to slide through, and the locking assembly is used to limit the sliding of the push rod.

The first drive rod and the second drive rod are rotated to drive the first lifting assembly and the second lifting assembly to lift in opposite directions. After the first lifting assembly and the second lifting assembly have moved, the locking assembly is locked at both ends of the push rod, thereby limiting the sliding of the push rod.

[0014] Optionally, the locking assembly includes a limiting sleeve, which is threadedly sleeved on the end of the push rod, and both ends of the push rod are provided with a limiting sleeve.

[0029] The following is combined with Figure 1-8 This application is described in further detail. Example 1

[0030] The embodiment of the present application discloses a chemical fiber drying device.

[0031] Reference Figure 1 , Figure 2 , Figure 3 A chemical fiber drying device comprises a box body 1. A feed port 2 is provided at one end of the box body 1, and a discharge port 3 is provided at the other end of the box body 1. A dryer 4 is fixedly installed at the end of the box body 1 where the discharge port 3 is provided, and an air outlet of the dryer 4 is connected to the inside of the box body 1, so that the dryer 4 can supply air to the inside of the box body 1.

[0032] Reference Figure 3 , Figure 4, an air outlet 5 is provided at one end of the box 1 away from the dryer 4. The chemical fiber is put into the box 1 from the discharge port 3, and then the chemical fiber is moved out of the box 1 from the discharge port 3. Then the dryer 4 is started, and the dryer 4 sends air into the box 1, thereby accelerating the drying speed of the chemical fiber. In the production process of the chemical fiber, a traction device is provided in the process downstream of the box 1 to pull the chemical fiber, so that the chemical fiber continuously enters the box 1 for drying.

[0033] At the same time, the dryer 4 supplies air at one end of the box body 1 where the discharge port 3 is provided, so that the temperature inside the box body 1 gradually increases from one end of the box body 1 close to the feed port 2 to the other end, thereby gradually accelerating the drying speed of the chemical fiber from one end of the box body 1 close to the feed port 2 to the other end, and the humidity is also high at the end of the box body 1 close to the feed port 2. The evaporation speed of the chemical fiber at the end of the box body 1 close to the feed port 2 is slow and the humidity is high, thereby reducing the evaporation speed of the water on the chemical fiber, thereby reducing the evaporation speed of the water fast enough to cause the water inside the chemical fiber to be difficult to evaporate after condensation.

[0034] Reference Figure 4 , Figure 5 , the two inner side walls of the box body 1 are both provided with a first lifting assembly 6 and a second lifting assembly 7. The first lifting assembly 6 includes a first lifting plate 61, a first slider 62 and a first connecting rod 63. The first slider 62 is fixedly mounted on the first lifting plate 61. The inner side wall of the box body 1 is provided with a first slide groove 8 for the first slider 62 to be lifted and slid. There are multiple first lifting rods, and the first connecting rod 63 is vertically fixedly mounted on the bottom side of the first lifting plate 61. The second lifting assembly 7 includes a second lifting plate 71, a second slider 72 and a second connecting rod 73. The second slider 72 is fixedly mounted on the second lifting plate 71. The inner side wall of the box body 1 is provided with a second slide groove 9 for the second slider 72 to be lifted and slid. There are multiple second lifting rods, and the second connecting rod 73 is vertically fixedly mounted on the top side of the second lifting plate 71.

[0035] Reference Figure 3 , Figure 4 A plurality of first transmission rollers 10 and second transmission rollers 11 are arranged inside the box body 1. First mounting seats 12 are arranged at both ends of the first transmission roller 10. The first transmission roller 10 is rotatably plugged into the first mounting seats 12. Second mounting seats 13 are arranged at both ends of the second transmission roller 11. The second transmission roller 11 is rotatably plugged into the second mounting seats 13. The first transmission rollers 10 and the second transmission rollers 11 are arranged alternately and spaced along the transmission direction of the chemical fiber. The top side of the first mounting seat 12 is fixedly connected to one end of the first connecting rod 63 away from the first lifting plate 61, and the bottom side of the second mounting seat 13 is fixedly connected to one end of the second connecting rod 73 away from the second lifting plate 71.

[0036] When the first lifting plate 61 and the second lifting plate 71 are lifted or lowered, the first lifting plate 61 drives each first transport roller 10 to be lifted or lowered, and the second lifting plate 71 drives each second transport roller 11 to be lifted or lowered.

[0037] Reference Figure 2 , Figure 4 The first lifting plate 61 and the second lifting plate 71 are both fixedly installed with a pull rope 14, and the pull rope 14 slides upward and passes through the top side of the box body 1 and is fixedly installed with a counterweight 15. The counterweight 15 applies an upward pulling force to the first lifting plate 61 and the second lifting plate 71 through the pull rope 14, so as to facilitate the first lifting plate 61 and the second lifting plate 71 to be lifted and lowered.

[0038] Reference Figure 4 , Figure 6 A first driving mechanism 16 is installed between the first lifting assembly 6 and the second lifting assembly 7 located on the same side of the box body 1. The first driving mechanism 16 includes a push rod 161, a first driving rod 162, a second driving rod 163 and a locking assembly 164. One end of the first driving rod 162 is hinged to the rod body of the push rod 161, and the other end of the first driving rod 162 is hinged to the bottom side of the first lifting plate 61. One end of the second driving rod 163 is hinged to the rod body of the push rod 161, and the other end of the second driving rod 163 is hinged to the top side of the second lifting plate 71. Through holes for the push rod 161 to slide through are provided at both ends of the box body 1. The locking assembly 164 includes a limiting sleeve 1641, which is threadedly sleeved on the end of the push rod 161, and both ends of the push rod 161 have a limiting sleeve 1641 and are located outside the box body 1.

[0039] The push rod 161 is pulled to move. Since the first lifting plate 61 and the second lifting plate 71 can only be lifted and slid, the first driving rod 162 and the second driving rod 163 are rotated, thereby driving the first lifting plate 61 and the second lifting plate 71 to lift and lower in opposite directions.

[0040] Reference Figure 4 , Figure 6 , both ends of the push rod 161 are hinged to multiple extension rods 17 in sequence, and both ends of the push rod 161 are sleeved with support tubes 18. The support tube 18 is fixedly installed on the inner wall of the box body 1, and the limiting sleeve 1641 is threadedly sleeved on the extension rod 17. When the push rod 161 is pulled to drive the first lifting plate 61 and the second lifting plate 71 to rise and fall, the push rod 161 is kept completely inside the box body 1, allowing the extension rod 17 to enter and exit the box body 1 from the through hole. When the extension rod 17 enters the box body 1, the extension rod 17 is inside the support tube 18, and the extension rod 17 is supported by the support tube 18, thereby reducing the situation where the extension rod 17 rotates downward. At the same time, the extension rod 17 located outside the box body 1 rotates downward due to gravity, thereby reducing the extension rod 17 from hindering the equipment of the upstream and downstream processes of the box body 1.

[0041] Reference Figure 4 , Figure 5 , a clamp 19 is provided inside the box 1, and the clamp 19 is used to clamp the chemical fiber. Slide rods 20 are telescopically installed on both sides of the clamp 19, and a third slide groove 21 is provided on the inner wall of the box 1 for the slide rod 20 to slide along the length direction of the box 1. In this application, the third slide groove 21 is located on the push rod 161. The clamp 19 is installed with a second driving mechanism 22, and the second driving mechanism 22 includes a hose 221 and a blocking ring 222. One end of the hose 221 is fixedly connected to the clamp 19, and the blocking ring 222 is fixedly sleeved on the end of the hose 221 away from the clamp 19.

[0042] The clamp 19 is used to clamp the chemical fiber, and then the second driving mechanism 22 drives the clamp 19 to slide, so as to facilitate the movement of the chemical fiber from one end of the box body 1 close to the feed port 2 to the other end.

[0043] The implementation principle of a chemical fiber drying device in the embodiment of the present application is as follows: before drying the chemical fiber, the dryer 4 is started to preheat the inside of the box 1. Then the staff puts the clamp 19 between the two push rods 161 from the discharge end of the box 1, and pulls the slide bar 20 to insert it into the third slide groove 21. Then the hose 221 is inserted into the air outlet end of the dryer 4, and the blocking ring 222 is blocked. The wind blown out by the dryer 4 enters the inside of the hose 221, so that the hose 221 is straightened. The straightening of the hose 221 drives the clamp 19 to move toward the end of the box 1 where the feed port 2 is opened.

[0044] After the clamp 19 moves to the end of the box 1 where the feed port 2 is opened, the hose 221 is pulled out from the air outlet of the dryer 4, and the staff pulls the slide bar 20 to retract the clamp 19, and then takes the clamp 19 out of the box 1. After that, the staff first uses the clamp 19 to clamp the chemical fiber to be dried, and the chemical fiber clamped by the clamp 19 is laid flat. The staff puts the clamp 19 holding the chemical fiber back into the box 1.

[0045] After the clamp 19 holding the chemical fiber is placed in the box 1, the staff pulls the hose 221, so that the clamp 19 drives the chemical fiber to move to the end of the box 1 where the discharge port 3 is opened. Then the staff takes out the clamp 19 at the end of the box 1 where the discharge port 3 is opened, and removes the chemical fiber from the clamp 19.

[0046] After the chemical fiber is removed from the clamp 19, the first driving mechanism 16 drives the first lifting plate 61 to descend and drives the second lifting plate 71 to rise, so that the first transmission roller 10 squeezes the chemical fiber from top to bottom and the second transmission roller 11 squeezes the chemical fiber from bottom to top, thereby bending the chemical fiber inside the box 1.

[0047] In the present application, the staff first places the chemical fiber in a straight line into the box 1, and then the first driving mechanism 16 drives the first lifting component 6 and the second lifting component 7 to lift and lower in opposite directions, so that the chemical fiber is bent, thereby reducing the difficulty of feeding due to complex paths in traditional technologies, thereby improving the efficiency of drying the chemical fiber. Example 2

[0048] The embodiment of the present application discloses a chemical fiber drying device.

[0049] Reference Figure 8 The difference between a chemical fiber drying device in the embodiment of the present application and the embodiment 1 is that the locking assembly 164 is different. The locking assembly 164 includes a limiting rod 1642, and the rod body of the push rod 161 is provided with a plurality of first limiting holes. The plurality of first limiting holes are arranged at intervals along the length direction of the push rod 161, the top side of the box body 1, the first lifting plate 61 and the second lifting plate 71 are all provided with second limiting holes, the inner bottom wall of the box body 1 is provided with a limiting groove, and the limiting rod 1642 is penetrated through the first limiting hole, the second limiting hole and the limiting groove.

[0050] The implementation principle of a chemical fiber drying device in an embodiment of the present application is: after pulling the push rod 161 to drive the first lifting plate 61 and the second lifting plate 71 to rise and fall, use the limit rod 1642 to pass through the first limit hole and the second limit hole and then insert into the limit groove, so as to facilitate limiting the movement of the push rod 161.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
