Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating roller technology, specifically to an easily movable electromagnetic heating roller. Background Technology

[0002] As a core piece of equipment in industrial production for key processes such as material heating and calendering, electromagnetic heating rollers are widely used in key industrial fields such as plastics processing, rubber vulcanization, and textile printing and dyeing. Their performance is directly related to product quality stability and production efficiency improvement.

[0003] However, existing traditional electromagnetic heating rollers still have significant technical limitations in practical applications: traditional equipment is generally bulky and heavy, and moving the equipment requires the assistance of external hoisting equipment or manual labor, which not only makes the operation process cumbersome, but also seriously restricts the flexibility of production scheduling and overall efficiency, becoming a prominent bottleneck affecting the continuity of modern production. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an easily movable electromagnetic heating roller that can transfer electromagnetic heating rollers of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily movable electromagnetic heating roller, comprising a U-shaped base plate, four self-locking casters mounted on the lower surface of the U-shaped base plate, support plates fixedly connected to both sides of the upper surface of the U-shaped base plate, a drive mechanism connected between the two support plates, a plurality of equally spaced circular holes I on the drive mechanism, a storage mechanism slidably connected to the drive mechanism, a fixing component for fixing the storage mechanism being detachably connected inside the circular holes I, and an L-shaped limiting plate fixedly connected to the upper surface of the U-shaped base plate.

[0007] Furthermore, the driver is a reversible motor.

[0008] Furthermore, the storage mechanism includes a rectangular tube slidably connected to a rectangular rod, a winding drum fixedly connected to the periphery of the rectangular tube, a second circular hole matching the first circular hole on the rectangular tube, and a braided belt fixedly connected to the winding drum, the lower end of the braided belt being annular.

[0009] Furthermore, the fixing component includes a plug rod that matches the first and second circular holes. The lower end of the plug rod is fixedly connected to a threaded rod, the upper end of the plug rod is fixedly connected to a nut, and a nut is threaded onto the threaded rod.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 3An easily movable electromagnetic heating roller includes a U-shaped base plate 1. Four self-locking casters 2 are installed on the lower surface of the U-shaped base plate 1. Support plates 3 are fixedly connected to both sides of the upper surface of the U-shaped base plate 1. A drive mechanism is connected between the two support plates 3. The drive mechanism has several equally spaced circular holes 4. A storage mechanism is slidably connected to the drive mechanism. A fixing component for fixing the storage mechanism is detachably connected inside the circular holes 4. An L-shaped limiting plate 5 is fixedly connected to the upper surface of the U-shaped base plate 1.

[0016] In use, the easily movable electromagnetic heating roller of this utility model is first moved by pushing the U-shaped base plate 1, which is then moved to the target working position by the four self-locking casters 2 installed on its lower surface. Once in position, the self-locking pedals of the casters 2 are pressed down to lock the wheels and prevent slippage, ensuring operational stability. The spacing between the storage mechanisms is adjusted according to the length of the electromagnetic heating roller to be lifted. The axial distance between the two storage mechanisms needs to be adjusted. The annular structure at the lower end of the braided tape 12 on the winding drum 10 is hooked onto the lifting lug or roller shaft end of the electromagnetic heating roller (the braided tape 12 is made of polyester industrial yarn, 50mm wide, with a breaking strength ≥5000N to ensure load-bearing safety). The drive mechanism is then activated, causing the rectangular rod 8 and the winding drum 10 to rotate synchronously, winding the braided tape 12 to lift the electromagnetic heating roller. At this time, stepless speed regulation from 0 to 300 rpm can be achieved by adjusting the pulse frequency to ensure a smooth lifting process. When the electromagnetic heating roller rises to contact the lower surface of the L-shaped limit plate 5, the roller body can be prevented from shaking by squeezing, and the rotating shaft 7 is driven to rotate counterclockwise, releasing the braided belt 12 to make the roller body descend slowly. During the lowering process, the descent speed can be adjusted by controlling the pulse frequency until the roller body reaches the target position. Through the above operations, this utility model can realize the rapid movement, flexible distance adjustment and safe lifting of the electromagnetic heating roller, which is suitable for the operation needs of rollers of different lengths and specifications. Moreover, through mechanical limit and buffer design, the operational stability and equipment safety are effectively improved.

[0017] like Figure 1 As shown, the driving mechanism includes a driver 6 fixedly connected to one of the support plates 3. The output end of the driver 6 is fixedly connected to a rotating shaft 7. The rotating shaft 7 is rotatably connected to the two support plates 3 through bearings. The middle section of the rotating shaft 7 is a rectangular rod 8 with a square cross-section. Circular holes 4 are equally spaced on the rectangular rod 8.

[0018] Specifically, by activating the driver 6, the rotating shaft 7 can be rotated, thereby causing the rectangular rod 8 and the storage mechanism connected to the rectangular rod 8 to rotate, so as to realize the raising and lowering of the electromagnetic heating roller.

[0019] like Figure 1 and Figure 2 As shown, the driver 6 is a forward and reverse rotating motor.

[0020] Specifically, after receiving an external control signal (pulse + direction), the driver 6 controls the stator winding current switching through its internal drive circuit to drive the rotor to achieve forward and reverse rotation and speed regulation. When a forward rotation pulse is input, the motor drives the shaft 7 to rotate clockwise, the winding drum 10 winds up the braided tape 12, and raises the electromagnetic heating roller; when a reverse rotation pulse is input, the motor rotates counterclockwise, releases the braided tape 12, and lowers the electromagnetic heating roller. By adjusting the pulse frequency (100-5000Hz), stepless speed regulation from 0-300rpm can be achieved to meet the stable lifting requirements under different working conditions.

[0021] like Figure 3 As shown, the storage mechanism includes a rectangular tube 9 slidably connected to a rectangular rod 8, a winding drum 10 fixedly connected to the periphery of the rectangular tube 9, a second round hole 11 matching the first round hole 4 on the rectangular tube 9, and a braided belt 12 fixedly connected to the winding drum 10, the lower end of the braided belt 12 being annular.

[0022] Specifically, the inner wall of the rectangular cylinder 9 is fitted with the rectangular rod 8 with a clearance of 0.5mm, allowing it to slide along the axial direction of the rectangular rod 8. A winding drum 10 is welded to its outer wall, and a braided strip 12 (made of polyester industrial yarn, 50mm wide, with a breaking strength ≥5000N) is wound around the surface of the winding drum 10. The lower end of the braided strip 12 is sewn into a ring shape for hooking the lifting lugs or roller end of the electromagnetic heating roller. The side wall of the rectangular cylinder 9 has a second round hole 11 that matches the first round hole 4, and the rectangular rod 8 is detachably fixed by a fixing component.

[0023] like Figure 3 As shown, the fixing assembly includes a plug rod 13 that matches the first circular hole 4 and the second circular hole 11. The lower end of the plug rod 13 is fixedly connected to a threaded rod 14, and the upper end of the plug rod 13 is fixedly connected to a nut 15. A nut 16 is threadedly connected to the threaded rod 14.

[0024] Specifically, when the rectangular tube 9 slides to the target position, the insertion rod 13 is passed through the second round hole 11 and the first round hole 4 in sequence, and the nut 16 is tightened to connect with the threaded rod 14 until the nut 16 is close to the lower surface of the rectangular tube 9. This locks the axial position of the storage mechanism, thereby adjusting the position between the storage mechanisms. This makes it easier to adjust the distance between the two braided belts 12, which is convenient for lifting electromagnetic heating rollers of different lengths.

[0025] like Figure 1 As shown, a rubber pad 17 is fixedly connected to the lower surface of the L-shaped limiting plate 5, and reinforcing plates 18 are fixedly connected to both sides of the L-shaped limiting plate 5. The other end of the reinforcing plate 18 is fixedly connected to the support plate 3.

[0026] Specifically, the L-shaped limiting plate 5 is welded to the middle of the upper surface of the U-shaped base plate 1, and a rubber pad 17 (5mm thick, Shore hardness 60°) is adhered to the lower surface. When the electromagnetic heating roller is lifted, it moves upward until the electromagnetic heating roller abuts against the lower surface of the limiting plate 5. The rubber pad 17 is used to increase the friction between the electromagnetic heating roller and the limiting plate 5 to prevent collision damage, and also to prevent the electromagnetic heating roller from shaking under the action of compression. Two reinforcing plates 18 are respectively welded between the two sides of the L-shaped limiting plate 5 and the support plate 3 to improve the deformation resistance of the L-shaped limiting plate 5.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
