Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric heater manufacturing technology, and in particular to a grinding device for electric heater tubes used in electric heater manufacturing. Background Technology
[0002] Electric heating tubes are made by inserting heating wires into seamless metal tubes (such as carbon steel tubes, titanium tubes, stainless steel tubes, and copper tubes), filling the gaps with magnesium oxide powder which has good thermal conductivity and insulation, and then shrinking the tube. They are then processed into various shapes required by the user.
[0003] In the production process of electric heaters, the polishing of the heating elements is a crucial step. Polished heating elements have a smoother surface, which helps improve the heat transfer efficiency and overall performance of the heater. However, the problem of collecting the heating elements during polishing is often overlooked. Traditional collection methods mostly rely on manual labor, which is inefficient and labor-intensive. Relying on the heating elements to fall freely into the collection box can easily damage them during collection, affecting subsequent production processes.
[0004] Therefore, there is a need to design a heating element grinding device for electric heater production that can automatically collect heating elements, save manpower, and prevent damage to the heating elements. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a heating element grinding device for electric heater production that can automatically collect heating elements, save manpower, and prevent damage to the heating elements.
[0006] Technical Solution: A grinding device for electric heating tubes used in the production of electric heaters includes a grinding machine, a conveying trough, a gantry frame, an electric slide rail, a connecting plate, a drive mechanism, a sensor, and a collecting rack. The grinding machine has a conveying trough in its middle section. The electric heating tubes are placed in the conveying trough and ground by the grinding machine. During grinding, the tubes automatically move to the left within the conveying trough. A gantry frame is installed on the left side of the grinding machine, through which the conveying trough passes. Electric slide rails are installed on both the front and rear sides of the gantry frame. A connecting plate is slidably connected to the electric slide rail, and the connecting plate is connected to a moving part of the electric slide rail. The electric slide rail drives the connecting plate to move up and down. A drive mechanism is located between the two connecting plates. A sensor is connected to the middle right side of the gantry frame, and a controller is installed on the gantry frame. The sensor and the electric slide rail are electrically connected to the controller. A collecting rack is connected to the left side of the grinding machine. The bottom surface of the collecting rack is oriented with a higher front and lower back. The drive mechanism drives the ground electric heating tubes to move to the left and collect them in the collecting rack.
[0007] Furthermore, it is particularly preferred that the drive mechanism includes a mounting plate, a guide rod, a drive roller, a motor, a limit block, and a return spring. Guide rods are slidably connected to both connecting plates, and the top of the guide rods is connected to the mounting plate. The drive roller is rotatably connected between the two mounting plates. A motor is mounted on one of the mounting plates. The motor is electrically connected to the controller, and the motor output shaft is connected to the drive roller. A limit block is connected to the guide rod and is located above the connecting plate. A return spring is wound around the guide rod, and the two ends of the return spring are connected to the guide rod and the bottom of the connecting plate, respectively.
[0008] In addition, it is particularly preferred that a rubber sleeve is also included. The outer side of the drive roller is fitted with a rubber sleeve. The rubber sleeve can increase the friction with the heating element, ensuring that the drive roller can smoothly drive the heating element to move when it rotates. The rubber sleeve also has the ability to deform, increasing the contact area with the heating element.
[0009] In addition, it is particularly preferred that the device also includes rollers. Multiple rollers are installed on the bottom left side of the conveying trough. The rollers reduce the friction between the heating element and the conveying trough, so that the heating element moves smoothly and prevents wear during movement.
[0010] In addition, it is particularly preferred that the device also includes a baffle, which is connected to the left side of the collection rack. The baffle can prevent the heating element from falling out of the left side due to inertia when it falls into the collection rack.
[0011] In addition, it is particularly preferred that a protective pad is included, with the inner side of the collection rack connected to the protective pad, which protects the heating element and prevents it from being worn when it falls into the collection rack.
[0012] Beneficial effects: This utility model uses an electric slide rail to drive the connecting plate downwards, so that the rubber sleeve on the drive roller contacts the heating tube. The drive roller rotates and drives the polished heating tube to continue moving to the left. There is no need to squeeze and push through the next heating tube, which reduces the squeezing between the ends of the heating tubes and reduces the chance of wear. The heating tubes removed from the conveying groove will fall into the collection rack and slide backwards along the collection rack for centralized collection. There is no need to collect them one by one manually, which reduces manpower loss and also prevents the heating tubes from falling freely and being damaged during collection.

Detailed Implementation
[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0018] Example: A grinding device for electric heating tubes used in the production of electric heaters, such as... Figure 1-3 As shown, the system includes a grinder 1, a conveyor trough 2, a gantry frame 3, an electric slide rail 4, a connecting plate 5, a mounting plate 6, a guide rod 7, a drive roller 8, a motor 9, a sensor 10, a collecting rack 11, a limit block 12, and a return spring 13. The grinder 1 has a conveyor trough 2 in its middle. The heating element is placed inside the conveyor trough 2 and ground by the grinder 1. During grinding, the heating element automatically moves to the left within the conveyor trough 2. A gantry frame 3 is installed on the left side of the grinder 1. The conveyor trough 2 passes through the gantry frame 3. Electric slide rails 4 are installed on both the front and rear sides of the gantry frame 3. Connecting plates 5 are slidably connected to the electric slide rails 4, and the connecting plates 5 are connected to the moving parts of the electric slide rails 4. The electric slide rails 4 drive the connecting plates 5 to move up and down. Guide rods 7 are slidably connected to both connecting plates 5. A mounting plate 6 is connected to the top of the guide rod 7. A drive roller 8 is rotatably connected between the two mounting plates 6. A motor 9 is installed on one side of the mounting plate 6. The output shaft of the motor 9 is connected to the drive roller 8. A limit block 12 is connected to the guide rod 7. The limit block 12 is located above the connecting plate 5. A return spring 13 is wound around the guide rod 7. The two ends of the return spring 13 are connected to the bottom of the guide rod 7 and the connecting plate 5, respectively. A sensor 10 is connected to the middle of the right side of the gantry 3. A controller is set on the gantry 3. The sensor 10, the electric slide rail 4 and the motor 9 are all electrically connected to the controller. A collection rack 11 is connected to the left side of the grinder 1. The bottom surface of the collection rack 11 is set with the front higher than the back. The drive mechanism is used to drive the heated tube that has been ground to move to the left and collect it in the collection rack 11.
[0019] like Figure 1 and Figure 3 As shown, it also includes a rubber sleeve 14. The outer side of the drive roller 8 is fitted with a rubber sleeve 14. The rubber sleeve 14 can increase the friction with the heating element, ensuring that the drive roller 8 can smoothly drive the heating element to move when it rotates. The rubber sleeve 14 also has the ability to deform, increasing the contact area with the heating element.
[0020] like Figure 1As shown, it also includes rollers 15. Multiple rollers 15 are installed on the bottom left side of the conveying trough 2. The rollers 15 reduce the friction between the heating element and the conveying trough 2, so that the heating element moves smoothly and prevents wear when the heating element moves.
[0021] like Figure 1 As shown, it also includes a baffle 16. The left side of the collection rack 11 is connected to the baffle 16, which can prevent the heating element from falling out from the left side due to inertia when it falls into the collection rack 11.
[0022] like Figure 1 As shown, it also includes a protective pad 17. The inner side of the collection rack 11 is connected to the protective pad 17, which protects the heating element and prevents it from being worn when it falls into the collection rack 11.
[0023] In use, start the grinder 1 and place the heating element to be ground on the right side of the conveyor trough 2. When the heating element contacts the grinding component of the grinder 1, the outer wall of the heating element will be ground. At the same time, the heating element will also move to the left under the force of the grinder 1 to achieve full grinding. When the heating element moves directly below the sensor 10, the sensor 10 detects the heating element and sends a signal. After receiving the signal, the controller controls the electric slide rail 4 to move the connecting plate 5 downward. At the same time, the motor 9 drives the drive roller 8 to rotate clockwise. The connecting plate 5 drives the drive roller 8 downward through the mounting plate 6. When the rubber sleeve 14 contacts the heating element, the return spring 13 will undergo adaptive deformation to prevent excessive pressure on the heating element when the drive roller 8 moves downward. At the same time, the clockwise rotation of the drive roller 8 can drive the heating element. Continuing to move to the left, when the heating element moves away from directly below the sensor 10, the sensor 10 can no longer detect the heating element. The controller controls the electric slide rail 4 to move the connecting plate 5 upward, and at the same time controls the motor 9 to stop running. The connecting plate 5 drives the drive roller 8 to move upward and reset through the mounting plate 6. After the heating element is detached from the conveying groove 2, it falls into the collection rack 11 for collection. When the collection rack 11 has collected an appropriate amount of heating elements, people can collect and store them. In this way, the rotation of the drive roller 8 can drive the polished heating element to continue to move to the left, preventing the ends of the heating elements from squeezing each other. After the heating element is removed from the conveying groove 2, it can slide backward along the collection rack 11 for collection and storage, reducing the manual collection steps, reducing manpower loss, and also preventing the heating element from being damaged when it falls freely during collection.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
