Description

Technical Field

[0001] This utility model relates to the technical field of ring transmission mechanisms, and in particular to an air-cooled ring transmission mechanism. Background Technology

[0002] A ring transmission mechanism is a structure that enables a product to rotate sequentially at various stations distributed around its circumference. Its rotating structure typically has fixtures on its surface to hold the product in place. A turntable structure drives the fixtures and the product to move synchronously. This turntable-type rotating structure offers stable transmission and high precision. However, this turntable structure has a low pressure tolerance; increasing pressure on the fixture can easily damage the turntable, making it unsuitable for pressure-formed products.

[0003] Therefore, it is necessary to further innovate the existing ring transmission mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an air-cooled ring transmission mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The present invention discloses an air-cooled ring transmission mechanism, comprising a sealed box and a rotating seat rotatably connected inside the sealed box; the sealed box contains a rotating module for driving the rotating seat to rotate; two air pipes are connected to the bottom of the sealed box; and multiple lever assemblies are evenly distributed on the rotating seat.

[0007] Furthermore, the lever assembly includes a fixed rod fixed to the rotating seat; a push block is fixed to the body of the fixed rod; a positioning groove is provided on the surface of the push block; the cross-section of the positioning groove is an isosceles triangle.

[0008] Furthermore, the fixing rod is provided with two strip grooves; a pin is slidably connected inside the strip groove; the pin is fixed to the push block; the fixing rod is provided with a through hole; the length direction of the through hole and the length direction of the strip groove are both arranged along the radial direction of the rotating seat; a bolt is slidably connected to the upper part of the through hole; nuts are threadedly connected to both sides of the bolt; the bolt is fixed to the push block.

[0009] Furthermore, the rotating module includes a motor and a driven gear fixed on the rotating base; one end of the motor is fixed to the sealed box; the other end of the motor is fixed to a coupling; and a driving gear meshing with the driven gear is fixed on the coupling.

[0010] Furthermore, a fixed shaft is fixed on the sealing box; the rotating seat is rotatably connected to the fixed shaft.

[0011] With the above structure, the beneficial effects of this utility model are as follows: a support platform is fixed inside the sealed box for placing the mold; the height of the lever assembly is higher than the height of the support platform; valve bodies are connected to two air pipes, one of which is used to discharge the gas inside the sealed box to form a vacuum environment. The other air pipe is used to inject nitrogen into the sealed box; the rotating module drives the rotating seat to rotate, so that each lever assembly rotates synchronously by the same central angle, and the lever assembly pushes the mold to rotate by the same central angle, so that each mold is transferred to the next station; the structure used to push the mold is the lever assembly, and when the mold is pressed, the lever assembly does not bear pressure, which can be used for conveying products formed by pressure molding.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, the air-cooled ring transmission mechanism of this utility model includes a sealed box 2 and a rotating seat 5 rotatably connected inside the sealed box 2; the sealed box 2 is provided with a rotating module for driving the rotating seat 5 to rotate; two air pipes 9 are connected to the bottom of the sealed box 2; and multiple lever assemblies 1 are evenly distributed on the rotating seat 5.

[0022] A support platform is fixed inside the sealed box 2 for placing the mold; the height of the lever assembly 1 is higher than the height of the support platform; valve bodies are connected to two air pipes 9, one of which is used to discharge the gas inside the sealed box 2 to form a vacuum environment. The other air pipe 9 is used to inject nitrogen into the sealed box 2; the rotating module drives the rotating seat 5 to rotate, so that each lever assembly 1 rotates synchronously by the same central angle, and the lever assembly 1 pushes the mold to rotate by the same central angle, so that each mold is transferred to the next station; the structure used to push the mold is the lever assembly 1. When the mold is pressed, the lever assembly 1 does not bear pressure, and can be used for the conveying of pressure-formed products.

[0023] In a preferred embodiment of the present invention, the lever assembly 1 includes a fixed rod 102 fixed on the rotating seat 5; a push block 101 is fixed on the rod body of the fixed rod 102; a positioning groove 10101 is provided on the surface of the push block 101; the cross section of the positioning groove 10101 is an isosceles triangle.

[0024] The positioning groove 10101 extends through the upper and lower surfaces of the push block 101; the push block 101 is in direct contact with the mold. For a circular mold structure, the mold is positioned by the two isosceles sides of the positioning groove 10101, which is shaped like an isosceles triangle, ensuring that the axis of the mold is on the angle bisector of the isosceles triangle, thereby improving the conveying accuracy of the mold.

[0025] In a preferred embodiment of this utility model, the fixing rod 102 is provided with two strip grooves 10201; a pin 103 is slidably connected inside the strip groove 10201; the pin 103 is fixed to the push block 101; the fixing rod 102 is provided with a through hole 10202; the length direction of the through hole 10202 and the length direction of the strip groove 10201 are both arranged along the radial direction of the rotating seat 5; a bolt 105 is slidably connected to the through hole 10202; nuts 104 are threadedly connected to both sides of the bolt 105; the bolt 105 is fixed to the push block 101;

[0026] After the pin 103 is inserted into the strip groove 10201, it is used to guide the push block 101 to slide on the fixed rod 102. The two nuts 104 are used to limit the position of the bolt 105 in the through hole 10202. After the nuts 104 are loosened, the bolt 105 can slide in the through hole 10202, which can adjust the position of the push block 101 on the fixed rod 102 and adjust the distance of the push block 101 relative to the rotation center of the rotating seat 5.

[0027] In a preferred embodiment of this utility model, the rotating module includes a motor 4 and a driven gear 3 fixed on a rotating base 5; one end of the motor 4 is fixed on a sealing box 2; the other end of the motor 4 is fixed with a coupling 7; and a driving gear 6 meshing with the driven gear 3 is fixed on the coupling 7.

[0028] The motor 4 drives the rotating seat 5 to rotate through the coupling 7, the driving gear 6 and the driven gear 3; the motor 4 is fixed on the bottom plate 201 of the sealing box 2; the driving gear 6 is rotatably connected to the bottom plate 201 of the sealing box 2.

[0029] In a preferred embodiment of this utility model, a fixed shaft 8 is fixed on the sealing box 2; the rotating seat 5 is rotatably connected to the fixed shaft 8.

[0030] The above description is only a preferred embodiment of the present utility model.
