The rotary pad printing machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a rotary pad printing machine, including a worktable 1, a turntable 11 on the top of the worktable 1, a support frame 12 fixedly installed on the top of the turntable 11, an mounting frame 2 fixedly installed on one side of the worktable 1, a translation mechanism 3 installed on the top of the mounting frame 2, a lifting mechanism 4 installed on the translation mechanism 3, and an adsorption mechanism 5 installed on the lifting mechanism 4. The support frame 12 is used to place products, the adsorption mechanism 5 is used to adsorb and fix the products in the support frame 12, the lifting mechanism 4 is used to pull the adsorption mechanism 5 and the product as a whole to move in the vertical direction, and the translation mechanism 3 is used to pull the lifting mechanism 4, the adsorption mechanism 5 and the product as a whole to move in the horizontal direction.

[0022] Furthermore, the top of the turntable 11 is provided with a feeding area 111 and a discharging area 112, and four support frames 12 are provided, which are arranged in an array around the circumference of the turntable 11.

[0023] Furthermore, the adsorption mechanism 5 includes a connecting frame 51 and a suction cup 54. An upper plate 52 and a lower plate 53 are fixedly mounted on the connecting frame 51. A rotating rod 56 is rotatably mounted on the bottom of the upper plate 52, and a second motor 55 is fixedly mounted on the top of the upper plate 52. The suction cup 54 is fixedly mounted on the lower plate 53. An eccentric block 57 is fixedly mounted on the surface of the rotating rod 56. A second bevel gear 59 is fixedly connected to one end of the rotating rod 56. The output end of the second motor 55 passes through the bottom of the upper plate 52 and extends downwards. A first bevel gear 58 is fixedly connected to the output end of the second motor 55. The first bevel gear 58 meshes with the second bevel gear 59, and the first bevel gear 58 and the second bevel gear 59 cooperate to output the power of the second motor 55. The output power is converted into the rotational force of the rotating rod 56. A pressure plate 541 is provided inside the suction cup 54. A connecting rod 542 is fixedly connected to the top center of the pressure plate 541. The top end of the connecting rod 542 passes through the top of the suction cup 54 and extends upward. A trigger plate 544 is fixedly connected to the top end of the connecting rod 542. When the eccentric block 57 rotates around the axis of the rotating rod 56, the eccentric block 57 can squeeze the trigger plate 544, causing the pressure plate 541 to move vertically downward. A compression spring 543 is sleeved on the surface of the connecting rod 542. One end of the compression spring 543 is fixedly connected to the bottom of the trigger plate 544, and the other end of the compression spring 543 is fixedly connected to the top of the suction cup 54. The elastic force of the compression spring 543 can drive the pressure plate 541 to move vertically upward.

[0024] Furthermore, the lifting mechanism 4 includes a support frame 41, a sliding seat 44 is slidably installed inside the support frame 41, a telescopic cylinder 42 is fixedly installed on the top of the support frame 41, the output end of the telescopic cylinder 42 extends downward into the interior of the support frame 41, the output end of the telescopic cylinder 42 is fixedly connected to the top of the sliding seat 44, the sliding seat 44 is fixedly connected to the connecting frame 51, a moving plate 43 is fixedly installed on the surface of the support frame 41, and the telescopic cylinder 42 can pull the sliding seat 44 to slide along the interior of the support frame 41 by extending or shortening the output end.

[0025] Furthermore, the translation mechanism 3 includes a fixed frame 31, which is fixedly installed on the top of the mounting frame 2. Threaded rods 32 are rotatably mounted on the fixed frame 31. Two threaded rods 32 are provided. A first motor 33 is fixedly mounted on the fixed frame 31. A power transmission component 34 is provided between the output end of the first motor 33 and one end of the two threaded rods 32. The power transmission component 34 is used to convert the output power of the first motor 33 into the rotational force of the threaded rods 32. A moving plate 43 is threadedly mounted on the surface of the threaded rods 32. The rotational force of the threaded rods 32 can pull the moving plate 43 to move along the axis of the threaded rods 32. Preferably, the power transmission component 34 is a belt drive structure. A guide plate 21 is also fixedly mounted on the mounting frame 2. The guide plate 21 is arranged at an angle.

[0026] The working principle of this utility model is as follows: In actual operation, the staff places the product on the support frame 12 at the feeding area 111. Then the turntable 11 rotates, and the support frame 12 rotates synchronously with the turntable 11. During the process of the product moving from the feeding area 111 to the discharge area 112, the printing equipment prints the product.

[0027] After the turntable 11 pulls the product to the discharge area 112, the output end of the telescopic cylinder 42 extends downward and drives the sliding seat 44 to slide downward along the support frame 41. The sliding seat 44 moves and drives the suction mechanism 5 to move downward synchronously. When the bottom of the suction cup 54 is in contact with the top of the product, the second motor 55 drives the rotating rod 56 to rotate around its own axis through the first bevel gear 58 and the second bevel gear 59. The rotating rod 56 rotates and drives the eccentric block 57 to rotate synchronously around the axis of the rotating rod 56. The eccentric block 57 presses down on the trigger plate 544. The compression spring 543 contracts and increases its elasticity under the pressure of the trigger plate 544. The connecting rod 542 and the pressure plate 541 move downward synchronously. Then the second motor 55 is turned off. Under the action of atmospheric pressure, the suction cup 54 adsorbs and fixes the product.

[0028] The output end of the telescopic cylinder 42 shortens upward, causing the product to move upward away from the support frame 12. The first motor 33 drives two threaded rods 32 to rotate around their own axis through the power transmission component 34. The rotation of the threaded rods 32 drives the moving plate 43 to move synchronously along the axis of the threaded rods 32, thereby causing the lifting mechanism 4, the suction mechanism 5, and the product as a whole to move synchronously along the axis of the threaded rods 32. When the product reaches the top of the guide plate 21, the first motor 33 shuts off, and the second motor 55 drives the eccentric block 57 to rotate around the axis of the rotating rod 56. The eccentric block 57 separates from the trigger plate 544, the compression spring 543 releases its elasticity and drives the pressure plate 541 to move upward. At this time, the suction cup 54 releases its suction and fixation on the product, and the product falls onto the guide plate 21 under its own gravity. The product then slides down the guide plate 21 onto the conveyor belt for subsequent processing.
