Description
Technical Field
[0001] The utility model relates to the field of heat treatment equipment, in particular to heat treatment equipment for spinning processing. Background Art
[0002] Specialty fibers refer to chemical fibers with unique physical and chemical structures, properties, and uses, or possessing special functions. During the spinning process, some complex specialty fibers require a series of sophisticated post-processing steps, such as cyclization, cross-linking, metal chelation, high-temperature heat treatment, surface physical and chemical treatment, and plasma treatment, to ultimately transform them into the desired specialty fibers. Heat treatment requires the use of heat treatment equipment, the most commonly used of which is a hot air drying oven.
[0003] When the hot air drying box is in use, a placement rack is provided in the drying chamber, and a placement net is installed on the placement rack through a cross bar with a slide groove, and relevant products are placed on the placement net for heat treatment. However, in the existing hot air drying box, the placement rack can be quickly moved by the wheels at the bottom, which is convenient for taking out materials. However, there is no blocking limit structure at the entrance and exit of the drying chamber. When the movable door is opened, if the entire drying box is not level and the entrance and exit tilt forward, the placement rack is likely to move outward at the moment the door is opened, which is very likely to hit the staff, posing a certain safety hazard. In addition, there is no blocking structure on the cross bar with a slide groove on the placement rack. When the placement rack is pulled outward, it will move from the slope pad. At this time, the placement rack is in a tilted state, and the placement net is likely to slide outward in the tilted state, and then multiple placement nets will slide at the same time, which is very likely to cause multiple placement nets to slide and fall to the ground, posing a risk of injuring staff.

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-Figure 5 As shown, a heat treatment equipment for spinning processing includes an oven 1, a drying chamber 2 is provided on the oven 1, a limiting structure 3 is installed in the drying chamber 2, and a placement rack 4 is provided inside the drying chamber 2, a placement rod 5 is installed on the placement rack 4, and a slide groove 6 is opened on the placement rod 5, a blocking structure 7 is installed at the front end of the placement rod 5, and a movable rack 8 is provided on the placement rod 5, a placement net 9 is fixed on the movable rack 8, a movable door 14 is provided on the oven 1, and a hot air blower 11 is provided on the top of the oven 1, an exhaust pipe 12 is installed on the top of the oven 1, a universal wheel 10 is installed at the lower end of the placement rack 4, a slope pad 13 is provided at the front end of the bottom of the oven 1, and a controller 15 is provided on the outer wall of the oven 1, and sliding rods are provided on the lower surfaces of both ends of the movable rack 8, and the sliding rods are slidably installed in the slide groove 6 on the placement rod 5.
[0021] When using heat treatment equipment for special fiber spinning processing, after opening the movable door 14, the placement rack 4 is moved outward, and the placement rack 4 is moved outward from the slope pad 13 to the outside of the oven 1 through the universal wheel 10, and then the movable rack 8 in the slide groove 6 on the placement rod 5 is removed, and the relevant products are placed on the placement net 9 on the movable rack 8, and then the placement work of the movable rack 8 is performed at one time. After the movable rack 8 is installed on the placement rod 5 through the slide rod, the blocking structure 7 is reset to play a blocking effect, and then the placement rack 4 is pushed into the drying chamber 2, the limiting structure 3 is operated, and the movable door 14 is closed. The entire equipment is started by the controller 15, and the hot air blower 11 runs to generate hot air, and the hot air acts on the drying chamber 2, thereby drying the product with heat treatment, and the gas with water vapor is discharged from the exhaust pipe 12 to ensure the drying effect. When the drying is completed, wait for the product inside the drying chamber 2 to cool, then open the movable door 14, and pull the placement rack 4 outward to take the material.
[0022] Through the above implementation scheme, the limiting structure 3 includes a fixed seat 301, a circular groove 302, a yield groove 303, a waist-shaped hole 304, a limiting rod 305, a pin 306, a stud 307 and a locking block 308. The circular groove 302 and the yield groove 303 are provided on the fixed seat 301, and the fixed seat 301 is fixed on the inner wall of the drying chamber 2. The waist-shaped hole 304 is provided on the fixed seat 301. The limiting rod 305 is fixedly connected to the pin 306, and the pin 306 is provided in the waist-shaped hole 304. The stud 307 is fixed on the pin 306, and the locking block 308 is connected to the stud 307. Through the setting of the limiting structure 3, the entire placement rack 4 has a limiting and blocking effect, preventing the placement rack 4 from suddenly moving outward and hitting the staff, thereby ensuring safety in use.
[0023] When the shelf 4 with the product is moved into the drying chamber 2, the limiting rod 305 is rotated by the pin shaft 306 to make the limiting rod 305 horizontal, and then the limiting rod 305 is moved along the waist-shaped hole 304. The end of the limiting rod 305 is inserted into the circular groove 302 on the fixing seat 301, so that the limiting rod 305 remains horizontal, and the locking block 308 on the stud 307 is rotated to fix the pin shaft 306 and the limiting rod 305, so that the limiting rod 305 has good stability. When the rack 4 is pulled outward, the limit rod 305 acts as a barrier to prevent the rack 4 from moving outward suddenly and hitting the staff, thereby ensuring safety. Then, after loosening the locking block 308, the limit rod 305 is pulled so that its end is pulled out of the circular groove 302. Then, after loosening the limit rod 305, the limit rod 305 rotates in the clearance groove 303 through the pin shaft 306 until the limit rod 305 is in a suspended state. At this time, the limit rod 305 has completed the clearance, and the staff can smoothly use the external force to place the rack 4 to take materials. The structure is simple and the use effect is good.
[0024] Through the above implementation scheme, the blocking structure 7 includes a mounting groove 701, a blocking block 702, a countersunk hole 703, a connecting rod 704, a control rod 705, a return spring 706 and a connecting bolt 707. The mounting groove 701 is provided in the slide groove 6 on the placement rod 5, the countersunk hole 703 is provided on the blocking block 702, and the blocking block 702 is located in the mounting groove 701, the connecting rod 704 is fixedly connected to the control rod 705, and the connecting rod 704 passes through the placement rod 5, the return spring 706 is sleeved on the connecting rod 704, and the return spring 706 is located in the mounting groove 701, the connecting rod 704 and the blocking block 702 are fixedly connected by a connecting bolt 707, and a When the blocking structure 7 is installed and the movable frame 8 is installed on the placement rod 5, the sliding rods at both ends of the movable frame 8 exert a force on the blocking block 702 with the inclined surface. The blocking block 702 sinks in the installation groove 701 and compresses the return spring 706, which will not affect the rapid installation of the movable frame 8. After the movable frame 8 is installed, under the action of the return spring 706, the blocking block 702 rises and resets. At this time, the blocking block 702 blocks and limits the sliding rod of the movable frame 8, which can play a blocking role on the movable frame 8 in the process of pulling the entire placement frame 4 outward, preventing the occurrence of multiple movable frames 8 sliding and falling off at the same time due to the tilt of the placement frame 4, further improving the safety when pulling the placement frame 4 outward.
[0025] When the movable frame 8 is placed, the end of the slide rod at the lower end of the movable frame 8 is inserted into the slide groove 6 to push the movable frame 8. When the slide rod contacts the inclined surface of the blocking block 702, the blocking block 702 is forced to move down and enter the installation groove 701. During this process, the blocking block 702 brings the connecting rod 704 and the control rod 705 down, and the return spring 706 is compressed. During the sliding process of the slide rod in the slide groove 6, the blocking block 702 is always in the installation groove 701. When the movable frame 8 is installed, the slide rod no longer contacts the blocking block 702. Under the action of the return spring 706, the blocking block 702 When the movable frame 8 is moved outward by the sliding rod, the sliding rod contacts the blocking block 702 and is limited, which can prevent the movable frame 8 from falling off. When the movable frame 8 needs to be removed, the connecting rod 704 can be pulled down by the control rod 705, and the connecting rod 704 will descend to make way for the blocking block 702, and then the movable frame 8 can be pulled outward for disassembly. The structure is simple, the operation is convenient, and the use effect is excellent.
