Description

Technical Field

[0001] This invention relates to the field of welding equipment, and more particularly to a single-piece flow control heat preservation cylinder. Background Technology

[0002] Electrode insulation cylinders are key equipment for ensuring welding quality, especially in demanding projects such as nuclear power plants. They are required to provide a stable insulation environment (usually 100℃-150℃) for low-hydrogen electrodes to prevent moisture absorption by the coating, which can lead to defects such as porosity and cracks in the weld.

[0003] Existing welding rod insulation cylinders consist of a cylinder body (including an insulation layer), a heating element, a simple temperature controller, a power supply, and a cylinder lid with a sealing strip, used to insulate and store welding rods inside. However, in complex environments such as nuclear power plants, existing welding rod insulation cylinders have significant shortcomings: frequent opening of the lid for material removal leads to heat loss, resulting in poor temperature stability inside the cylinder; the welding rods stored inside are prone to moisture absorption or overheating, affecting the coating performance; and they have poor environmental adaptability, failing to withstand high humidity, salt spray, dust, and extreme temperatures, and are easily contaminated by foreign matter. These shortcomings not only necessitate frequent re-drying of the welding rods, increasing costs, but also restrict welding efficiency, quality, and safety, necessitating a more reliable insulation cylinder structure.

[0004] Furthermore, in high-safety-requirement work sites such as nuclear power engineering, the storage of welding rods (battery rod ends) must be strictly regulated. Losing welding rods (battery rod ends) at nuclear power sites is a major accident, requiring shutdown for inspection and retrieval. Lost welding rods (battery rod ends) may lead to safety accidents such as equipment damage. Summary of the Invention

[0005] The purpose of this invention is at least to provide a single-piece flow control insulation cylinder to avoid large-scale opening of the heat storage chamber, which would lead to a large loss of heat in the heat storage chamber. At the same time, it controls the recovery of welding rod heads and the removal of welding rods, thereby improving the safety, reliability and intelligence of the welding rod storage and use process.

[0006] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0007] One embodiment of the present invention provides a single-piece flow control insulation cylinder, wherein a heat storage chamber and a recovery chamber are provided inside the single-piece flow control insulation cylinder.

[0008] The heat storage chamber is used to heat-store welding rods, and a heating circuit is installed inside the heat storage chamber.

[0009] The heat storage tank has a welding rod output channel on its wall. The welding rod output channel is a long strip-shaped hole that allows only a single welding rod to pass through at the same time. The length of the welding rod output channel is adapted to the axial length of a single welding rod, and the width of the welding rod output channel is adapted to the diameter of a single welding rod.

[0010] The insulation cylinder is equipped with a bearing groove and a control component. The bearing groove is connected to the welding rod output channel, so that the welding rod can smoothly enter the bearing groove after passing through the welding rod output channel. The single-piece flow control insulation cylinder is equipped with an outlet adapted to the bearing groove. The control component is used to control the bearing groove to tilt and extend from the outlet when it is in the unlocked state. When the bearing groove is in the tilted extension state, the welding rod in the bearing groove is open to the outside.

[0011] The recycling bin is used to store welding rod heads. The recycling bin is equipped with a dispensing module for dispensing welding rod heads. The dispensing module has an embedded dispensing sensor, which is used to detect whether the welding rod head enters the recycling bin through the dispensing module.

[0012] The single-piece flow control insulation cylinder includes a central controller, which is connected to the delivery sensor and control components. The central controller is used to control the control components to unlock when it receives the delivery signal from the delivery sensor.

[0013] In some embodiments, a detection sensor is provided inside the trough or at the outlet to detect the presence or absence of welding rods.

[0014] The central controller is connected to the detection sensor signal. When the central controller receives a negative signal from the detection sensor while the control component is in the unlocked state, it controls the control component to switch to the locked state.

[0015] In some embodiments, the control components include a servo motor, a stop, and a push handle.

[0016] The outlet is located at the front end of the bearing groove, and the stop block is located at the middle, rear end, or between the two of the bearing groove.

[0017] A hand-push groove is provided on the body of the single-piece flow control insulation cylinder, and the hand-push handle is connected to the bearing extraction groove inside the single-piece flow control insulation cylinder through the hand-push groove.

[0018] The servo motor is used to drive the stop block to rotate. When the servo motor drives the stop block to the horizontal position, the stop block blocks the load-bearing slot from tilting upwards, thus limiting the load-bearing slot from tilting out of the outlet. When the servo motor drives the stop block to the vertical position, the load-bearing slot can be tilted out of the outlet by pushing the handle with the push handle.

[0019] The central controller is connected to the servo motor signal. When the central controller receives the release signal from the release sensor, it controls the servo motor to drive the stop block to the vertical state, or when it receives the negative signal from the detection sensor in the unlocked state of the control component, it controls the servo motor to drive the stop block to the horizontal state.

[0020] In some embodiments, a welding electrode support plate is provided inside the heat storage chamber. The welding electrode support plate can support the welding electrodes inside the heat storage chamber. The welding electrode support plate is tilted and fixed towards the welding electrode output channel. The plate surface of the welding electrode support plate forms a guide surface for the welding electrodes inside the heat storage chamber to reach the welding electrode output channel.

[0021] In some embodiments, the bearing groove includes a recess that allows only a single welding rod to slide into, the length of the recess being greater than the axial length of the single welding rod, and the width of the recess being adapted to the diameter of the single welding rod.

[0022] In some embodiments, the dispensing module is fixed relative to the cylinder, and the dispensing module includes a dispensing hole that penetrates both the dispensing module and the cylinder.

[0023] The delivery sensor includes a first sensor and a second sensor, which are stacked in the delivery module. The central controller is connected to the first and second sensors. The central controller can determine whether the welding rod head leaves or is put into the recycling bin based on the order in which the signals from the first and second sensors are received.

[0024] In some embodiments, the single-piece flow control insulation cylinder includes a constant temperature feedback controller, a temperature sensor is installed inside the heat storage chamber for real-time monitoring of the internal temperature of the heat storage chamber, the constant temperature feedback controller is connected to the temperature sensor and the heating circuit signal, and the constant temperature feedback controller controls the heating circuit based on the monitoring data of the temperature sensor.

[0025] In some embodiments, the single-piece flow control insulation cylinder includes a rechargeable battery, which is electrically connected to a heating circuit. The rechargeable battery is equipped with an overheat protection device to protect its safe operation.

[0026] In some embodiments, the heat storage tank is provided with a heat storage tank cover, which is normally locked with the assistance of a mechanical or electrical structure. When the heat storage tank cover is opened, a large number of welding rods are allowed to be inserted into the heat storage tank.

[0027] In some embodiments, the recycling bin is provided with a recycling bin cover, which is normally locked with the assistance of a mechanical or electrical structure. When the recycling bin cover is opened, a large number of welding rod heads can be taken out from the recycling bin. Attached Figure Description

Generally, the terms "comprising" and "including" only indicate the inclusion of explicitly identified technical elements, and these elements do not constitute an exclusive list; the apparatus or device may also include other technical elements.

[0036] To overcome the key defects of existing welding rod insulation cylinders exposed in harsh industrial environments such as nuclear power plants, this specification proposes a single-piece flow control insulation cylinder.

[0037] Figure 1 This is a structural schematic diagram of a single-piece flow control insulation cylinder according to some embodiments.

[0038] Figure 2 This is a side view of a single-piece flow control insulation cylinder according to some embodiments.

[0039] Figure 3 yes Figure 2 A schematic diagram of section AA shown in the figure.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the single-piece flow control insulation cylinder includes a cylinder body 10, which surrounds and defines an inner cavity. The inner cavity is divided into a heat storage chamber 2 and a recovery chamber 3 by an isolation wall 1. The heat storage chamber 2 and the recovery chamber 3 form independent chambers to form independent temperature zones.

[0041] In some embodiments, see Figures 1 to 2 The bottom of the cylinder 10 is provided with feet 11 for supporting the insulation cylinder. The top of the cylinder 10 is provided with a handle 12 for the welder to hold. The welder holds the handle 12 and places the insulation cylinder horizontally in place based on the feet 11 at the bottom of the cylinder 10.

[0042] The heat storage chamber 2 is used for heat storage of welding electrodes. A heating circuit is installed inside the heat storage chamber 2, including heating elements such as resistance wires, to heat the air inside the chamber. The heating circuit is controlled by an algorithm to maintain the temperature inside the chamber within the range of 80℃ to 120℃. In some embodiments, a heat insulation structure is provided on the wall of the heat storage chamber 2 to keep the chamber 2 warm, enabling batch and constant-temperature storage of welding electrodes.

[0043] Figure 4 yes Figure 3 Enlarged view of section B in the middle.

[0044] like Figure 4 As shown, a welding electrode output channel 21 is provided on the wall of the heat storage chamber 2. The welding electrode output channel 21 is an elongated hole that allows only a single welding electrode to pass through at the same time. The length of the welding electrode output channel 21 is adapted to the axial length of a single welding electrode, and the width of the welding electrode output channel 21 is adapted to the diameter of a single welding electrode. Specifically, the length of the welding electrode output channel 21 is slightly greater than the axial length of a single welding electrode, and the width of the welding electrode output channel 21 is slightly greater than the diameter of the welding electrode, thereby physically restricting the parallel output of multiple welding electrodes.

[0045] Taking a cylindrical welding electrode with a diameter d = 3.2 mm and an axial length l = 350 mm as an example, if two welding electrodes attempt to pass side by side, the minimum theoretical width requirement is W. 双焊条 =d+d 3 / 2 ≈ 3.2 + 2.77 = 5.97 mm, the width W of the electrode output channel 21 输出 <5.97 mm, allowing only a single welding electrode to pass through at the same time.

[0046] In some embodiments, based on Figure 2 As shown, the electrode output channel 21 is in the orientation indicated. Figure 2 The electrode output channel 21 is set in a horizontal (lateral) configuration. Its length is its lateral dimension, and its width is its vertical dimension. For ease of description, the following will continue to use... Figure 2 The directions shown are used as the basis for the explanation.

[0047] The insulation cylinder is equipped with a support groove 4 and a control component. The support groove 4 is connected to the welding electrode output channel 21. Specifically, the support groove 4 is along the length of the welding electrode output channel 21 (e.g., Figure 2 The lateral extension arrangement shown is as follows: Figure 4 As shown, one side of the bearing groove 4 is connected to the bottom side of the electrode output channel 21, and the bottom surface of the electrode output channel 21 and the top surface of the bearing groove 4 form a smooth transition surface, so that the electrode can smoothly enter the bearing groove 4 after passing through the electrode output channel 21.

[0048] like Figure 4 As shown, the support groove 4 includes a groove 41 for accommodating a single welding rod. The groove 41 allows only a single welding rod to slide into it. The length of the groove 41 is greater than the axial length of the single welding rod, and the width (or diameter) of the groove is adapted to the diameter of the single welding rod. Taking a cylindrical welding rod with a diameter d = 3.2 mm and an axial length l = 350 mm as an example, the length of the groove 41 is greater than the axial length l of the single welding rod. To accommodate only a single welding rod and prevent a second welding rod from getting stuck, the width of the groove 41 is greater than d and less than 2d. In some embodiments, the groove 41 is a semi-circular groove or an arc-shaped groove with an arc angle of less than 180°.

[0049] In some embodiments, the welding rods in the heat storage chamber 2 can be manually shaken to slide out through the welding rod output channel 21. In some embodiments, to facilitate the transfer of welding rods, a welding rod support plate 22 is provided in the heat storage chamber 2, which can partially support the welding rods in the heat storage chamber 2.

[0050] like Figure 3As shown, the electrode support plate 22 is suspended in the heat storage chamber 2 at a certain angle (e.g., greater than 15°) and fixed inclined towards the electrode output channel 21. The upper surface of the electrode support plate 22 forms a guide surface for the electrode in the heat storage chamber 2 to reach the electrode output channel 21. Figure 4 As shown, the upper surface of the electrode support plate 22, the lower side of the electrode output channel 21, and the upper side of the support groove 4 are smoothly and inclinedly connected. The electrode, which is displaced and supported on the electrode support plate 22, automatically slides into the support groove 4 through the electrode output channel 21 under the action of gravity. In some embodiments, the electrode support plate 22 is provided with baffles on its front and rear sides in the lateral direction, and a guide groove is formed between the front and rear sides of the electrode support plate 22 in the lateral direction to restrict the lateral displacement of the electrode and ensure that the electrode on the electrode support plate 22 can pass smoothly through the electrode output channel 21.

[0051] The cylinder 10 is provided with an outlet 13 adapted to the bearing groove 4. The outlet 13 is a hole penetrating the cylinder 10 and is located on the front side of the cylinder 10 in the transverse direction. The area of ​​the outlet 13 is slightly larger than the vertical cross-sectional area of ​​the bearing groove 4, so that the front end of the bearing groove 4 can extend out from the outlet 13.

[0052] In some embodiments, the carrying groove 4 is connected to the inner wall of the cylinder 10 outside the heat storage chamber 2 through a spring-assisted mechanism. The spring-assisted mechanism is arranged in a transverse direction. The carrying groove 4 can extend horizontally from the outlet 13 with the assistance of the spring-assisted mechanism, or it can be horizontally reset with the assistance of the spring-assisted mechanism. In the reset state, the carrying groove 4 is completely sealed inside the heat-insulating cylinder to prevent heat loss from the heat storage chamber 2.

[0053] The control component is used to control the tilting extension of the carrying slot 4 from the outlet 13 in its unlocked state (e.g.) Figure 1 and Figure 2 (The state of the support slot 4 shown). The control component is also used to control the support slot 4 to return to a horizontal state within the outlet 13 when it is locked. When the support slot 4 is in a state of tilted extension from the outlet 13, the welding rods inside the support slot 4 slide outward under gravity and are exposed outside the insulation cylinder. At this time, the welder can take out one welding rod from the support slot 4. The control component can be implemented in various ways. For example, the operation component can be implemented as a drive rotation mechanism to clamp the support slot 4 and rotate it, thereby switching the support slot 4 between the tilted state and the horizontal state.

[0054] In some embodiments, the heat storage chamber 2 is equipped with a heat storage chamber cover, which is normally locked with the assistance of a mechanical or electrical structure. For example, the heat storage chamber cover is normally locked by de-energizing an electromagnetic lock or by using a mechanical lock. In the normally locked state, welders (or other operators) are not authorized to open the heat storage chamber cover, preventing unauthorized operation from causing heat loss from the heat storage chamber 2 and maintaining a stable temperature within the heat storage chamber 2. The heat storage chamber cover can be unlocked with the assistance of a mechanical or electrical structure. For example, the heat storage chamber cover can be unlocked by energizing an electromagnetic lock or by using a key in conjunction with a mechanical lock. When the heat storage chamber cover is unlocked and opened, it is permissible to store welding rods in batches into the heat storage chamber 2.

[0055] The recycling bin 3 is used to store welding rod ends. It is isolated from and independent of the heat storage bin 2. The welding rod ends are used welding rods. The recycling bin 3 is equipped with a dispensing module for dispensing welding rod ends. The dispensing module has an embedded dispensing sensor that detects the entry of welding rod ends into the recycling bin 3 through the dispensing module. The dispensing module includes a dispensing hole 31 for dispensing welding rod ends. The dispensing hole 31 penetrates the cylinder 10 and communicates with the recycling bin 3, allowing the welder to insert the welding rod ends into the recycling bin 3 through the dispensing hole 31.

[0056] In some embodiments, the recycling bin 3 is equipped with a recycling bin cover, which is normally locked with the assistance of a mechanical or electrical structure. For example, the recycling bin cover is normally locked by de-energizing an electromagnetic lock or by using a mechanical lock. In the normally locked state, the welder is not authorized to open the recycling bin cover to prevent unauthorized removal of welding rod heads, which could lead to loss. The recycling bin cover can be unlocked with the assistance of a mechanical or electrical structure. For example, the recycling bin cover can be unlocked by energizing an electromagnetic lock or by using a key in conjunction with a mechanical lock. After leaving the work site, the recycling bin cover can be unlocked and opened, allowing a large number of welding rod heads to be removed from the recycling bin 3 for recycling.

[0057] In some embodiments, such as Figure 3 As shown, the heat storage bin cover and the recovery bin cover are combined into a single cylindrical cover 20. The cylindrical cover 20 is connected to the cylinder body 10 via a hinge, and is normally locked with the assistance of a mechanical lock 30. In the normally locked state, the welder does not have the authority to open the cylindrical cover 20. After leaving the work site, the cylindrical cover 20 is unlocked and opened, allowing a large number of welding rod ends to be retrieved from the recovery bin 3 for recycling, and allowing welding rods to be stored in batches in the heat storage bin 2 for heat storage, in preparation for the next operation to bring out single-piece flow control insulation cylinders.

[0058] The single-piece flow control insulation cylinder includes a central controller, which is signal-connected to the dispensing sensor and control components. The central controller controls the control components to unlock when it receives a dispensing signal from the dispensing sensor. In high-safety-requirement work sites such as nuclear power plants, the storage and heat preservation of each item must be strictly regulated to prevent items from being lost, which could lead to equipment damage or other safety hazards. In nuclear power plants, the loss of welding rods is a major accident, requiring a shutdown for inspection and retrieval. To prevent such accidents, welding rod heads must be placed in the recovery bin 3 for safekeeping and inventory. When the welding rod head is not recovered, the dispensing sensor does not detect a dispensing signal, locking the control components and preventing the tilting extension of the support slot 4, thus preventing the welder from retrieving the welding rod from the support slot 4. When the welding rod head is recovered, the dispensing sensor detects a dispensing signal, unlocking the control components, allowing the support slot 4 to tilt and extend again.

[0059] In some embodiments, the spring-assisted mechanism can be an electric mechanism, with the central controller signal-connected to it. When the electrode head is not retracted, the delivery sensor does not detect a delivery signal, locking the spring-assisted mechanism and the control component. The spring-assisted mechanism does not horizontally eject the carrier slot 4 from outlet 13, and the control component does not tilt the carrier slot 4 outwards. The welder cannot remove the electrode from the carrier slot 4. When the electrode head is retracted, the control component is unlocked, and the spring-assisted mechanism horizontally ejects the carrier slot 4 from outlet 13. The control component can then tilt the carrier slot 4 outwards again. In other embodiments, the spring-assisted mechanism can be a manual mechanism. The carrier slot 4 can be horizontally ejected or reset by manually pressing the front end of the carrier slot 4 laterally. When the electrode head is not retracted, even if the carrier slot 4 horizontally ejects from outlet 13, the electrode in the carrier slot 4 is not tilted into place, and the welder cannot remove the electrode from the carrier slot 4.

[0060] This manual establishes a welding electrode output channel 21 that allows only single welding electrodes to pass through, and a support tray 4 that holds single welding electrodes. This ensures that the support tray 4 can only retrieve a single welding electrode from the heat storage chamber 2 at a time, allowing unused electrodes to be stored in the heat storage chamber 2. This prevents excessive welding electrodes 6 from entering the support tray 4, causing moisture absorption or temperature drops, and ensuring the stability of the welding electrode coating quality. Furthermore, by linking the delivery sensor and control components through a central controller, the welder's access rights are strictly limited. Welders can only retrieve a single welding electrode after the electrode head has been recovered, ensuring electrode head recovery, minimizing human intervention, and guaranteeing standardized and reasonable welding electrode retrieval and recovery processes.

[0061] In some embodiments, a detection sensor is provided inside the support groove 4 or at the outlet 13. The detection sensor is used to detect the presence or absence of welding rods. For example, the detection sensor is embedded in the bottom of the support groove 4 or the edge of the outlet 13. The detection sensor includes a capacitive proximity switch or an infrared sensor, etc.

[0062] The central controller is also connected to the detection sensor signal. When the central controller receives a negative signal from the detection sensor while the control component is in the unlocked state, it controls the control component to switch to the locked state. If the central controller receives a negative signal from the detection sensor while the control component is unlocked, it indicates that there is no welding rod in the bearing slot 4, meaning the welding rod has been removed by the welder. The central controller then generates a locking command immediately or with a delay, resetting the control component to the locked state. By setting up a central controller-based linkage control between the detection sensor and the control component, heat loss caused by an empty bearing slot 4 remaining externally is avoided.

[0063] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the control components include a servo motor, a stop block 44, and a push handle 42. The servo motor and the stop block 44 are housed inside an insulated cylinder. The outlet 13 is located at the front end of the support slot 4, and the stop block 44 is located at the middle, rear, or both of the support slot 4. The servo motor drives the stop block 44 to rotate; for example, the stop block 44 is connected to the servo motor shaft via a coupling. The stop block 44 has an elongated, strip-shaped structure.

[0064] like Figure 2 As shown, a push-pull groove 43 is provided on the side wall of the cylinder 10. The push-pull groove 43 has a certain curvature, and the push-pull handle 42 passes through the push-pull groove 43 and is connected to the load-bearing drawer 4 inside the insulation cylinder. The push-pull handle 42 is connected to the middle end, the rear end, or both of the load-bearing drawer 4. Specifically, the push-pull handle 42 is located on the front side of the stop block 44 in the lateral direction. In some embodiments, the load-bearing drawer 4 is rotatably connected to the inner wall of the cylinder 10 through a hinge, and the hinge is connected to the middle end of the load-bearing drawer 4 or between its front end and the middle end.

[0065] When the servo drive block 44 rotates to the horizontal position, the block 44 blocks the upward tilting of the bearing slot 4 from above, keeping the bearing slot 4 horizontal and preventing it from tilting out of the outlet 13. When the servo drive block 44 rotates to the vertical position, the block 44 moves away from above the bearing slot 4, releasing the bearing slot 4. By pushing the push handle 42 upward, the push handle 42 moves upward at the limit of the push slot 43, causing the rear of the bearing slot 4 to tilt upward, allowing the bearing slot 4 to tilt out of the outlet 13.

[0066] The central controller is also connected to the servo motor signal. When receiving a release signal from the release sensor, the central controller controls the servo motor to drive the stop block to a vertical position, or when receiving a negative signal from the detection sensor while the servo motor is unlocked, it controls the servo motor to drive the stop block to a horizontal position. When a release signal is received from the release sensor, the central controller outputs a command to drive the servo motor to drive the stop block 44 to a vertical position (unlocked position), and manually controls the push handle 42 to move upwards, causing the support slot 4 to extend tilted out from the outlet 13. In the unlocked state of the control components, i.e., when the stop block 44 remains in a vertical position, if the detection sensor outputs a negative signal, indicating that the welder has removed the welding rod from the support slot 4, the central controller outputs a command to drive the servo motor to drive the stop block 44 to a horizontal position (locked position), and the support slot 4 resets to a horizontal position.

[0067] Figure 5 This is a structural diagram of the delivery module shown in some embodiments.

[0068] In some embodiments, the dispensing module is fixed to the inner wall of the recycling bin 3. For example... Figure 5 As shown, the dispensing module includes a dispensing hole 31, which penetrates both the dispensing module itself and the cylinder 10.

[0069] The dispensing module includes dispensing sensors and a mounting base 34. The dispensing sensors include a first sensor 32 and a second sensor 33, both of which are three-wire NPN normally open metal proximity sensors. The first sensor 32 and the second sensor 33 are stacked together via the mounting base 34 and fixed to the inner wall of the recycling bin 3. The detection ports of the first sensor 32 and the second sensor 33 are coaxially arranged with the dispensing hole 31.

[0070] The central controller is signal-connected to the first sensor 32 and the second sensor 33. Specifically, the output signals of the first sensor 32 and the second sensor 33 are transmitted to the central controller through a level conversion circuit. When the electrode tip approaches, the output of the NPN normally open metal proximity sensor is low. When the electrode tip moves away, the output of the NPN normally open metal proximity sensor is high. The central controller employs precise timing logic control to ensure accurate capture of sensor signals and timing judgment.

[0071] Taking a scenario where the first sensor 32 is positioned close to the cylinder 10, and the second sensor 33 is stacked on top of the first sensor 32, the central controller determines the order in which the trigger signals (low-level signals) received from the first sensor 32 and the second sensor 33 are received, thus determining whether the welding rod head leaves or enters the recycling bin 3. When the welding rod head is entered, the first sensor 32 is triggered first, followed by the second sensor 33; the order is reversed when the welding rod head leaves the recycling bin 3. If the order is first sensor 32 → second sensor 33, it is determined that the welding rod head has entered the recycling bin 3; otherwise, it is determined that it has been retrieved.

[0072] In some embodiments, the central controller records the count of welding rod heads in the recycling bin 3 based on the order in which the welding rods pass through the first sensor 32 and the second sensor 33. If the triggering sequence of the delivery sensors is not as expected or is interrupted, the central controller will automatically ignore the signal, maintain the count, and ensure the accuracy of the data. Furthermore, the insulation cylinder also includes a quantity display screen, which is electrically connected to the central controller and is used to display the number of welding rod heads in the recycling bin 3.

[0073] In some embodiments, the single-piece flow control insulation cylinder includes a constant temperature feedback controller. A temperature sensor is installed inside the heat storage chamber 2 to monitor the internal temperature of the heat storage chamber 2 in real time. The constant temperature feedback controller is connected (including electrical connection) to the temperature sensor and the heating circuit. Based on the monitoring data from the temperature sensor, it controls the heating circuit. Its main function is to dynamically adjust the heating power by monitoring the internal temperature of the heat storage chamber 2 in real time to ensure that the internal temperature of the heat storage chamber 2 remains stable within a set range. In some embodiments, the constant temperature feedback controller also provides overheat protection and overcurrent protection functions for the heating circuit. When the temperature or current exceeds the set safety threshold, the constant temperature feedback controller automatically cuts off the heating circuit to prevent safety accidents. In some embodiments, the single-piece flow control insulation cylinder also includes a temperature display screen, which is electrically connected to the temperature sensor and is used to display the internal temperature of the heat storage chamber 2 on the temperature display screen.

[0074] In some embodiments, the single-piece flow control insulation cylinder includes a rechargeable battery that is electrically connected to a heating circuit, so that the temperature inside the heat storage chamber 2 of the welding rod insulation cylinder can be continuously maintained in the absence of an external power source.

[0075] In some embodiments, the rechargeable battery employs an overheat protection device to protect its safe operation. Specifically, the rechargeable battery is installed in isolation within the heat storage chamber 2, and measures such as arranging temperature sensors around the rechargeable battery for temperature detection and using physical insulation materials to block external heat sources are employed to ensure battery safety. When the temperature exceeds 40°C, the constant temperature feedback controller triggers a load power regulation mechanism to reduce the output power of the rechargeable battery and simultaneously issues an alarm, ensuring that the battery operates within a safe temperature range.
