Description

Technical Field

[0001] This utility model relates to the field of spinning insulation technology, specifically to the insulation structure of a spinning box. Background Technology

[0002] With the progress and development of society, the use of spinning boxes is becoming more and more widespread. Spinning boxes are also known as spinning insulation boxes. Pre-spinning is a process in the manufacture of chemical fibers. It is a process in which certain polymer compounds are made into colloidal solutions or melted into melts and then extruded through the fine holes of the spinneret to form chemical fibers. Before the pre-spinning equipment is put into operation, the spinning components of the equipment need to be preheated. Then, the insulation box is used to transport each spinning component to the front of the equipment for installation.

[0003] The utility model patent with authorization announcement number CN221758147U, currently disclosed in the field of spinning insulation technology, specifically relates to a spinning box insulation structure, including a trolley and an insulation box. The insulation box is fixed to the top of the trolley, and the top of the insulation box has several access ports, each covered with an insulation cover. Although when the spinning components are removed one by one, the corresponding upper or lower insulation support plate will continue to block the heat inside the insulation box, thus reducing heat loss to a certain extent compared to existing technologies.

[0004] However, during the process of removing the spinning assembly separately, when the spinning element is moved upwards from the insulation box, the perforated box may be partially outside the insulation box and partially inside during its movement. In this situation, the multiple holes on the surface of the perforated box allow cold air from the outside to flow into the insulation box, thus reducing the effectiveness of the insulation box in minimizing heat loss. Furthermore, during the operation of the forward and reverse motors to adjust the raising and lowering of the perforated box, the motors may continue to run even after the perforated box has reached its designated position. During this period, the motors are prone to operating under high load, which is detrimental to their long-term use. Utility Model Content

[0005] The purpose of this invention is to provide a heat-insulating structure for spinning boxes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spinning box insulation structure, comprising: a base plate, with casters installed at all four corners of the lower surface of the base plate; a handle fixedly connected to one end of the upper surface of the base plate; an insulation box fixedly connected to the upper surface of the base plate; a first electric heater installed at one end inside the insulation box; multiple perforated boxes vertically arranged inside the insulation box; partitions fixedly connected to both the upper and lower ends of each perforated box; an insulation cover fixedly connected to the top of each partition; the insulation cover fitting snugly against the upper surface of the insulation box; and the interior of the perforated boxes... A limiting component is provided above the part, which is connected to the partition. A pair of vertical cylinders are fixed to the lower surface of the bottom partition. A sliding rod is provided inside one of the vertical cylinders, and the bottom end of the sliding rod is fixedly connected to the heat preservation box. A lead screw is threaded inside the other vertical cylinder, and the lead screw is rotatably connected to the heat preservation box through a sealed bearing. The bottom end of the lead screw is fixedly connected to the output shaft of the forward and reverse motor. The housing of the forward and reverse motor is fixedly connected to the heat preservation box. A baffle unit is installed on the outside of the top partition, and an auxiliary unit is installed below the bottom partition.

[0007] Preferably, the baffle unit includes: a square tube, which is fitted onto the outside of the top partition, the top of the square tube is fixedly connected to the contact surface of the insulation box, a soft sheet is pressed against the bottom of the square tube, a retaining ring is pressed against the lower surface of the soft sheet, a bolt is inserted into the lower surface of the retaining ring, the bolt passes through the retaining ring and the soft sheet in sequence and is threadedly connected to the square tube, and the inner wall of the soft sheet is in contact with the outer wall of the partition.

[0008] Preferably, the film has a double-layer structure, and an insulation layer is fixed between the two layers of the film.

[0009] Preferably, a plurality of ball bearings are slidably engaged on the inner wall of one side of the vertical cylinder, and the ball bearings are in contact with the outer wall of the slide rod.

[0010] Preferably, the auxiliary unit includes: a distance sensor, which is installed below the bottom partition and connected to the insulation box. A transparent cover is provided above the distance sensor, and a housing is fixedly attached to the lower surface of the transparent cover. The bottom end of the housing is fixedly connected to the insulation box.

[0011] Preferably, a second electric heater is installed at the rear end of the inner cavity of the square tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This spinning box insulation structure has the following advantages: Through the coordinated operation of various structural components, the user places the spinning parts to be insulated into the perforated box, controls the limiting components to prevent displacement and collision during transport. After stacking, the forward and reverse motors are driven to rotate the lead screw counterclockwise. Through threaded transmission and sliding rod limiting, the perforated box and partition are stored in the insulation box. The insulation cover is closed and the first and second electric heaters are turned on to maintain the specified temperature inside the box for insulation storage. When retrieving individual spinning parts, the forward and reverse motors are driven to rotate the lead screw clockwise, and multiple perforated boxes are moved out one after another. During the process, the square tube and soft sheet wrap the outside of the perforated box to isolate the cold air entering during removal, thereby improving the insulation box's effect of reducing heat loss.

[0013] Through the coordinated operation of various components, during the lifting and lowering of the insulated box by the forward and reverse motors, the distance sensor can monitor the distance between the bottom partition and the bottom of the insulated box in real time. When the distance reaches the minimum or maximum threshold, the distance sensor will send a signal to the external control module. The control module will then send a stop command to the forward and reverse motors. At this time, the pressure force between the insulated cover and the upper surface of the insulated box will no longer increase, and the vertical cylinder will not exert a pressure force against the top of the lead screw. This can prevent the forward and reverse motors from being under high load, which is beneficial for their long-term use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a spinning box insulation structure, comprising: a base plate 1, universal wheels 2 installed at the four corners of the lower surface of the base plate 1, a handle 3 fixedly connected to one end of the upper surface of the base plate 1, an insulation box 4 fixedly connected to the upper surface of the base plate 1, a first electric heater 5 installed at one end inside the insulation box 4, multiple perforated boxes 6 vertically arranged inside the insulation box 4, partitions 7 fixedly connected to both the upper and lower ends of the perforated boxes 6, an insulation cover 8 fixedly connected to the top of the top partition 7, the insulation cover 8 fitting against the upper surface of the insulation box 4, and a limiting component 9 provided at the upper part of the perforated boxes 6. The limiting component 9 is connected to the partition 7. A pair of vertical cylinders 10 are fixedly connected to the lower surface of the bottom partition 7. A sliding rod 13 is provided inside one vertical cylinder 10. The bottom end of the sliding rod 13 is fixedly connected to the heat preservation box 4. A lead screw 11 is threaded inside the other vertical cylinder 10. The lead screw 11 is rotatably connected to the heat preservation box 4 through a sealed bearing. The bottom end of the lead screw 11 is fixedly connected to the output shaft of the forward and reverse motor 12. The housing of the forward and reverse motor 12 is fixedly connected to the heat preservation box 4. A baffle unit is installed on the outside of the top partition 7. An auxiliary unit is installed below the bottom partition 7.

[0019] In the specific implementation process, it is worth noting that the base plate 1, as the load-bearing foundation of the entire spinning box insulation structure, is made of high-strength metal material, possessing good rigidity and stability, and capable of bearing the weight of the insulation box 4 and all its internal components. The casters 2 are casters with brakes, allowing users to flexibly move the spinning box insulation structure according to actual needs, and when movement is not required, they can be fixed by the braking device to prevent accidental slippage. The handle 3 is designed according to ergonomic principles, allowing users to easily grip and apply force to push or pull the spinning box insulation structure. The insulation box 4 is made of multi-layered insulation materials, which has good insulation performance and can effectively reduce the heat exchange between the internal heat and the external environment. The first electric heater 5 is a high-efficiency and energy-saving electric heating element, and its power can be adjusted according to the insulation requirements of the spinning parts to ensure the stability of the internal temperature of the insulation box 4. The perforated box 6 has multiple appropriately sized holes evenly distributed on it to allow heat to pass through. The front of the perforated box 6 is an open structure for placing and removing the spinning parts. The partition 7 not only connects the perforated box 6 and supports other components, but also has a certain heat insulation function to reduce heat exchange. The heat transfer between the lower perforated boxes 6 is achieved through an insulation cover 8 made of the same insulation material as the insulation box 4, with a sealing strip at the edge. When it is in contact with the upper surface of the insulation box 4, it effectively prevents heat loss from the top. The limiting component 9 is a known structure, and its specific structure and working principle are the same as those in the utility model patent with authorization announcement number CN221758147U in the prior art. Therefore, it will not be described in detail here. This ensures the limiting effect on the spinning parts. The two vertical cylinders 10 are high-precision metal cylinders. The inner wall of one vertical cylinder 10 is smooth, while the inner wall of the other vertical cylinder 10 is open. The internal thread ensures the stability of the hole box 6 during lifting and lowering. The slide rod 13 is a hard alloy rod with a chrome-plated surface, which has good wear resistance and corrosion resistance, and can slide stably with the vertical cylinder 10 for a long time. The lead screw 11 is a trapezoidal threaded lead screw with a self-locking function, which can keep the position of the hole box 6 unchanged when the forward and reverse motors 12 stop running. The forward and reverse motors 12 are high-performance servo motors with fast response speed and high control accuracy, which can accurately drive the lead screw 11 to rotate according to the control command. The blocking unit and auxiliary unit will be described in detail later.

[0020] Furthermore, the baffle unit includes: a square tube 14, which is fitted onto the outside of the top partition 7. The top of the square tube 14 is fixedly connected to the contact surface of the insulation box 4. A soft sheet 15 is pressed against the bottom of the square tube 14. A retaining ring 17 is pressed against the lower surface of the soft sheet 15. A bolt 18 is inserted into the lower surface of the retaining ring 17. The bolt 18 passes through the retaining ring 17 and the soft sheet 15 in sequence and is threadedly connected to the square tube 14. The inner wall of the soft sheet 15 is in contact with the outer wall of the partition 7.

[0021] In the specific implementation process, it is worth noting that the materials used to make the square tube 14 and the insulation box 4 can provide effective wrapping and support for the outside of the perforated box 6 without affecting its lifting and lowering. The soft sheet 15 is made of silicone, which has good elasticity and sealing properties. When the perforated box 6 is partially removed from the insulation box 4, the soft sheet 15 can tightly fit the outer wall of the partition 7 to prevent cold air from entering the interior of the insulation box 4. The abutment ring 17 is a metal ring with a polished surface. Its contact surface with the soft sheet 15 is smooth, which can apply pressure evenly and ensure the sealing effect between the soft sheet 15 and the partition 7. The bolt 18 is a high-strength stainless steel bolt with good tensile strength and corrosion resistance, which can firmly fix the abutment ring 17 and the soft sheet 15 to the square tube 14.

[0022] Furthermore, the film 15 has a double-layer structure, with an insulation layer 16 fixed between the two layers of film 15.

[0023] In the specific implementation process, it is worth noting that the insulation layer 16 is made of aerogel felt material, which has an extremely low thermal conductivity and can effectively prevent heat from being transferred through the soft sheet 15, thereby further improving the insulation performance of the insulation box 4.

[0024] Furthermore, multiple ball bearings are slidably engaged on the inner wall of one side of the vertical cylinder 10, and the ball bearings are in contact with the outer wall of the slide rod 13.

[0025] In the specific implementation process, it is worth noting that the ball bearings can be fixed but cannot be separated from the vertical cylinder 10 on one side, which can greatly reduce the friction between the vertical cylinder 10 and the slide rod 13, making the lifting and lowering of the hole box 6 smoother, while reducing energy loss and extending the service life of the equipment.

[0026] Furthermore, the auxiliary unit includes: a distance sensor 19, which is installed below the bottom partition 7 and connected to the insulation box 4. A transparent cover 21 is provided above the distance sensor 19, and a housing 20 is fixedly attached to the lower surface of the transparent cover 21. The bottom end of the housing 20 is fixedly connected to the insulation box 4.

[0027] In the specific implementation process, it is worth noting that the distance sensor 19 is a laser distance sensor, which has the advantages of high measurement accuracy and fast response speed. It can accurately monitor the distance between the bottom partition 7 and the bottom of the insulated box 4 in real time and transmit the data to the control module. The transparent cover 21 is made of high-strength transparent plastic, which has good light transmission and impact resistance, and can protect the distance sensor 19 from collisions with external objects and dust contamination. The housing 20 is a sealed metal housing, which can effectively prevent moisture and corrosive gases from entering and protect the electronic components inside the distance sensor 19 from damage.

[0028] Furthermore, a second electric heater 22 is installed at the rear end of the inner cavity of the square tube 14.

[0029] In the specific implementation process, it is worth noting that the second electric heater 22 is a small ceramic electric heater with high heating efficiency and small size. It is installed at the rear end of the inside of the square tube 14 and can heat the perforated box 6 located inside the square tube 14 to ensure the temperature stability of the spinning parts during the removal process. At the same time, the power of the second electric heater 22 can be adjusted according to actual needs to adapt to different working environments and the heat preservation requirements of the spinning parts.

[0030] Working principle: The principle of storing spinning parts: When the user starts the operation, the spinning parts to be insulated and stored are first placed inside the perforated box 6. Then, the limiting component 9 is used to limit the spinning parts inside the perforated box 6. This effectively prevents the spinning parts from shifting during subsequent transfer, avoiding collisions caused by shifting, thus ensuring the quality and integrity of the spinning parts and laying a good foundation for subsequent insulated storage. After the spinning parts are neatly stacked in the perforated box 6, the key storage stage begins. The forward and reverse motor 12 is driven to rotate the lead screw 11 counterclockwise. During the counterclockwise rotation of the lead screw 11, a threaded transmission effect is generated on one side of the vertical cylinder 10. At the same time, the slide rod 13 slides and limits the other side of the vertical cylinder 10. The two work together to ensure that the perforated box 6 and the partition 7 are stably and orderly stored inside the insulated box 4. After storage is completed, the insulated cover 8 is tightly fitted and pressed against the upper surface of the insulated box 4 to achieve a seal. Next, the first electric heater 5 and the second electric heater 2 are turned on. The two work together to keep the internal temperature of the insulation box 4 stable within the designated temperature range carefully set according to the characteristics of the spinning parts and the insulation requirements, thereby enabling effective insulation and storage of the spinning parts.

[0031] The principles of spinneret removal, heat preservation, and motor protection: If a separate spinning element needs to be removed later, the forward and reverse motor 12 is driven again to rotate the lead screw 11 clockwise. Under the action of the lead screw 11 rotating clockwise, the multiple vertically arranged perforated boxes 6 will move out of the insulation box 4 one after another. During this process, the square tube 14 and the soft sheet 15 will wrap the outside of the perforated box 6. When the perforated box 6 is partially outside and partially inside the insulation box during its movement out of the insulation box, the square tube 14 and the soft sheet 15 can effectively isolate the cold air from the outside of the insulation box 4, greatly improving the insulation box's ability to reduce heat loss. At the same time, the forward and reverse motor 12 adjusts the perforated box 6. During lifting, the distance sensor 19 monitors the distance between the bottom partition 7 and the bottom of the insulation box 4 in real time. When the distance reaches the preset minimum or maximum threshold, the distance sensor 19 quickly sends a signal to the external control module. The control module immediately sends a stop operation command to the forward and reverse motors 12. At this time, the pressure force between the insulation cover 8 and the upper surface of the insulation box 4 no longer increases, and the vertical cylinder 10 will not exert a pressure force on the top of the lead screw 11. This effectively prevents the forward and reverse motors 12 from being under high load, which is conducive to their long-term stable use and ensures the reliability and stability of the entire spinning box insulation structure.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
