[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A drying device for transformer production includes a box with a cover plate on top, wherein an air inlet pipe and an air outlet pipe are provided on the side wall of the box, and a heating plate is also provided inside the box.

[0007] A material frame is suspended inside the box. A limiting mechanism for fixing the material frame is provided on the inner wall of the box, and a feeding mechanism is provided inside the material frame. A driving mechanism is provided at the bottom of the box. The driving mechanism is connected to the bottom of the material frame through a transmission mechanism, and a pushing mechanism is also provided on the driving mechanism, which is movably connected to the feeding mechanism and the transmission mechanism respectively.

[0008] The feeding mechanism includes a screw fixed to the bottom wall of the material frame by a bearing. The bottom end of the screw is provided with a U-shaped notch.

N-pole magnetic blocks are provided at the top of the base plate and the bottom of the cylinder. A boss driven by an electric push rod is provided at the bottom of the base plate, wherein a crossbar is radially arranged on the boss, and a top rod extending into the housing is provided at the top of the crossbar. The top rod is connected to a ring sleeved on multiple sets of sleeves, wherein a groove I for accommodating a slider is arranged around the inner side wall of the ring.

[0012] Preferably, the limiting mechanism includes an annular seat that is sleeved on the material frame, wherein the annular seat is connected to the outer wall of the material frame through a connecting rod, and a sliding groove II is arranged around the outer wall of the annular seat. A bolt is screwed onto the side wall of the box, wherein one end of the bolt extends into the sliding groove II, and the end of the bolt in the sliding groove II has a hemispherical structure.

[0023] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] A drying device for transformer production includes a box 1 with a cover plate on the top. An air inlet pipe and an air outlet pipe are provided on the side wall of the box 1. A heating plate is also provided inside the box 1. Hot air is introduced through the air inlet pipe to heat and dry the products inside the box 1, and then discharged through the air outlet pipe. At the same time, the hot air inside the box 1 can be reheated by the heating plate 2 to indirectly heat and dry the products. Alternatively, without introducing hot air, the heating plate 2 alone heats the inside of the box 1 to heat and dry the products inside the box 1.

[0025] A material frame 3 is suspended inside the box 1. A limiting mechanism 4 for fixing the material frame 3 is provided on the inner wall of the box 1. A feeding mechanism 5 is provided inside the material frame 3. A driving mechanism 6 is provided at the bottom of the box 1. The driving mechanism 6 is connected to the bottom of the material frame 3 through a transmission mechanism 7. A pushing mechanism 8 is also provided on the driving mechanism 6, which is movably connected to the feeding mechanism 5 and the transmission mechanism 7 respectively.

[0026] The feeding mechanism 5 includes a screw 51 fixed to the bottom wall of the material frame 3 by a bearing. The bottom end of the screw 51 is provided with a U-shaped notch 54. The screw 51 inside the material frame 3 is sleeved with a screw tube 52, and the screw tube 52 is provided with multiple sets of perforated plates 53. The perforated plates 53 are rectangular structures, and the size of the perforated plates 53 is adapted to the size of the opening inside the material frame 3. The screw 51 is screwed to the screw tube 52.

[0027] The driving mechanism 6 includes a cylinder 61 driven by a motor 63 and disposed on the bottom wall of the housing 1, wherein a circular plate 62 located inside the housing 1 is disposed at the top of the cylinder 61.

[0028] The transmission mechanism 7 includes multiple sets of vertical rods I71 disposed on the top of the circular plate 62, wherein the bottom of the material frame 3 is provided with vertical rods II72 corresponding to the vertical rods I71, and a sleeve 73 is sleeved at the connection between the vertical rods I71 and II72. A slider 74 is disposed on the outer wall of the sleeve 73. The cross-section of the vertical rods I71 and II72 is a polygonal structure, wherein the size of the opening inside the sleeve 73 is adapted to the size of the vertical rods I71 and II72.

[0029] The pushing mechanism 8 includes a sliding opening 81 vertically arranged on the cylinder 61 corresponding to the U-shaped notch 54. A retaining plate 82 that can be embedded in the U-shaped notch 54 is provided in the sliding opening 81, and a base plate 83 is provided at the bottom of the retaining plate 82. N-pole magnetic blocks 84 are provided at the top of the base plate 83 and the bottom of the cylinder 61. A boss 85 driven by an electric push rod 86 is provided at the bottom of the base plate 83. A crossbar 87 is radially arranged on the boss 85, and a top rod 88 extending into the housing 1 is provided at the top of the crossbar 87. The top rod 88 is connected to a ring 89 sleeved on multiple sets of sleeves 73. A groove I810 for accommodating the slider 74 is arranged around the inner side wall of the ring 89.

[0030] The limiting mechanism 4 includes an annular seat 41 that is sleeved on the material frame 3. The annular seat 41 is connected to the outer wall of the material frame 6 through a connecting rod 42. A sliding groove II 43 is arranged around the outer wall of the annular seat 41. A bolt 44 is screwed onto the side wall of the box 1. One end of the bolt 44 extends into the sliding groove II 43, and the end of the bolt 44 in the sliding groove II 43 has a hemispherical structure.

[0031] Preferably, the bottom of the cylinder 61 is provided with a toothed ring 64, wherein the toothed ring 64 is provided with a gear 65 that meshes with it, and the output shaft of the motor 63 is fixedly connected to the middle of the bottom of the gear 65.

[0032] like Figure 1 As shown, the circular plate 62 is located between multiple sets of push rods 88, and the bottom wall of the housing 1 is provided with through holes for the push rods 88 to pass through.

[0033] In this embodiment, a receiving groove with a cross-section of an arc is provided on the top surface of the boss 85, wherein a ball bearing 9 is provided in the receiving groove to abut against the bottom surface of the base plate 83.

[0034] The method of using this invention: The electric push rod 86 drives the boss 85 and the base plate 83 to push the clamping plate 82 upward within the sliding opening 81, thereby causing the top of the clamping plate 82 to embed into the U-shaped notch 54. Simultaneously, the boss 85, while moving upward, drives the crossbar 87 and the top rod 88 to move the ring 89 upward. The ring 89, through the sliding groove I810, hooks the slider 74, pushing the sleeve 73 upward, so that the sleeve 73 slides onto the vertical rod II72 and separates from the vertical rod I71. At this time, the motor 63 drives the cylinder 61 to rotate through the gear 65 and the gear ring 64, and the cylinder 61 drives the clamping plate 82 to drive the screw 51 to rotate inside the screw tube 52. At this time, the clamping plate 82 drives the base plate 83 to rotate on the ball 9, which in turn drives the screw tube 52 to move multiple sets of perforated plates 53 upward in the material frame 3 so that they can slide out from the top, so that people can place the product on the perforated plate 53 or remove the product from the perforated plate 53. The steps of the feeding mechanism 5 sliding into the material frame 3 are exactly the opposite.

[0035] like Figure 1 As shown, when material is placed on the feeding mechanism 5 for drying, the electric push rod 86 drives the boss 85 to move downward. Then, the N-pole magnetic block 84 on the cylinder 61 and the base plate 83, under the influence of like poles repulsion, will drive the clamping plate 82 to move downward within the sliding opening 81, causing the top of the clamping plate 82 to slide out from the U-shaped notch 54. When the driving mechanism 6 drives the material frame 3 to rotate through the transmission mechanism 7, the screw 51 will not rotate within the screw tube 52. When the boss 85 moves downward, it will drive the ring 89 downward through the crossbar 87 and the top rod 88. This causes the ring 89 to drive the slider 74 through the sliding groove I810, causing the sleeve 73 to move downward to the top of the vertical rod I71. This allows the sleeve 73 to hold the vertical rod I71... 1. When connected to vertical rod II72, during drying, the motor 63 drives multiple sets of vertical rods I71 to rotate through gear 65, gear ring 64, cylinder 61 and circular plate 62. The vertical rods I71 will drive the material frame 3 to rotate in the box 1 through sleeve 72 and vertical rod II73, so that the product in the material frame 3 can fully contact the hot airflow or heat in the box 1 to improve its drying efficiency and effect. When the sleeve 72 rotates, the ring 89 can prevent the sleeve 73 from sliding up and down on the vertical rods I71 and vertical rod II72 through the sliding groove I810 and slider 74. When the sleeve 73 rotates under the influence of external force, it will slide in the sliding groove I810 to prevent the ring 89 from affecting the rotation of the transmission mechanism 7.

[0036] When the material frame 3 rotates, it will drive the slide groove II 43 to slide on the bolt 44 through the connecting rod 42 and the ring seat 41, so that while the material frame 3 rotates, the limiting mechanism 4 can also effectively suspend and fix the material frame 3 in the top of the box 1.

[0037] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
