[0028] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0029] Please refer to Figures 1 to 4As shown in the figure, this embodiment provides a printing device for processing thermos cup lids, including a fixing frame 1 and a machine body 2. An imprinting assembly 3 for printing on the thermos cup lids 5 is installed inside the machine body 2. The imprinting assembly 3 involved in this embodiment has the same structure and working principle as the imprinting assembly disclosed in the Chinese patent with the publication number CN217649131U, and will not be elaborated here. The fixing frame 1 penetrates through the inside of the machine body 2. A conveyor belt 101 is installed inside the fixing frame 1. A driving motor 102 for driving the rotation of the conveyor belt 101 is fixedly installed at one end of the fixing frame 1. A number of clamping and positioning mechanisms 6 for clamping and fixing the thermos cup lids 5 are equidistantly installed on the conveyor belt 101;

[0030] The clamping and positioning mechanism 6 includes a bearing plate 601. The bearing plate 601 is fixedly connected to the conveyor belt 101. Vertical plates 602 are fixedly installed on both sides of the top of the bearing plate 601. Telescopic members 603 are slidably arranged on both vertical plates 602. One end of each of the two telescopic members 603 is fixedly connected to an arc-shaped clamping plate 607. Both arc-shaped clamping plates 607 are located between the two vertical plates 602;

[0031] Guide plates 4 are fixedly connected to both sides of the top of the fixing frame 1. The guide plates 4 include a holding part 402. The holding part 402 is arranged close to the imprinting assembly 3. A gradient part 401 is fixedly connected to one end of the holding part 402 close to the feed inlet of the imprinting assembly 3. When the end of the telescopic member 603 away from the arc-shaped clamping plate 607 passes through the gradient part 401, the gradient part 401 can squeeze the telescopic member 603, so that the arc-shaped clamping plate 607 moves towards the direction close to the thermos cup lid 5, and the thermos cup lid 5 can be clamped and fixed on the bearing plate 601 by the two arc-shaped clamping plates 607.

[0032] Specifically, the telescopic member 603 includes a sleeve 6031 and a plug rod 6032. The arc-shaped clamping plate 607 is fixedly connected to one end of the sleeve 6031. The other end of the sleeve 6031 slidably penetrates through the vertical plate 602. A limit slider 60321 is slidably arranged inside the sleeve 6031. One end of the plug rod 6032 is slidably inserted into the sleeve 6031 from the end away from the arc-shaped clamping plate 607 and then fixedly connected to the limit slider 60321. A pressing spring 6033 is arranged inside the sleeve 6031. One end of the pressing spring 6033 abuts against the inner wall of the sleeve 6031 close to the arc-shaped clamping plate 607, and the other end of the pressing spring 6033 abuts against one side of the limit slider 60321.

[0033] Working principle: When in use, start the drive motor 102 to drive the conveyor belt 101 to start rotating. Then, place the thermos cup lid 5 on the carrier plate 601 through the manipulator. The carrier plate 601 moves towards the feed port of the stamping assembly 3 through the conveyor belt 101. When the carrier plate 601 moves to the position of the tapered part 401, the tapered part 401 will squeeze the end of the insertion rod 6032 away from the arc-shaped clamping plate 607, causing the insertion rod 6032 to insert into the inside of the sleeve 6031. Furthermore, the limit slider 60321 will squeeze the abutting spring 6033, and then the sleeve 6031 will slide towards the center of the carrier plate 601, finally pressing the arc-shaped clamping plate 607 against the outer wall of the thermos cup lid 5 to complete the clamping and positioning operation of the thermos cup lid 5. Then, the fixed thermos cup lid 5 will move to the lower part of the stamping assembly 3 along with the conveyor belt 101 for printing. After printing, the thermos cup lid 5 is removed from the discharge port of the stamping assembly 3. When the printed thermos cup lid 5 moves out of the holding part 402, at this time, the pressure on the insertion rod 6032 is released, thus releasing the extrusion of the abutting spring 6033, and finally releasing the fixation of the thermos cup lid 5.

[0034] Specifically, in order to reduce the friction between the insertion rod 6032 and the guide plate 4, a roller seat 605 is fixedly connected to the end of the insertion rod 6032 away from the arc-shaped clamping plate 607. A roller 606 is rotatably installed on the roller seat 605, and the roller 606 can rollingly contact one side of the guide plate 4.

[0035] Specifically, in order to prevent the roller seat 605 from rotating relative to the sleeve 6031, a limit chute 60311 is provided on the inner wall of the sleeve 6031. A limit protrusion 60322 is fixedly connected to the limit slider 60321, and the limit protrusion 60322 is slidably arranged in the limit chute 60311.

[0036] Specifically, in order to enable the arc-shaped clamping plate 607 to move smoothly, a guide rod 608 is fixedly connected to one side of the arc-shaped clamping plate 607. The end of the guide rod 608 away from the arc-shaped clamping plate 607 slidably penetrates through the vertical plate 602.

[0037] Specifically, a return spring 604 is sleeved on the outer wall of the sleeve 6031. One end of the return spring 604 abuts against one side of the roller seat 605, and the other end of the return spring 604 abuts against one side of the vertical plate 602. Through this setting, when the guide plate 4 releases the extrusion of the insertion rod 6032, at this time, the arc-shaped clamping plate 607 can move away from the thermos cup lid 5 under the elastic force of the return spring 604, realizing the automatic reset of the arc-shaped clamping plate 607 for the next clamping operation.

[0038] Specifically, an irradiation induction plate 609 is fixedly connected to the top of the roller seat 605. Through this setting, it can be linked with the infrared sensor on the printing and pressing assembly 3. The linkage function between the irradiation induction plate 609 and the infrared sensor is the same as the working principle disclosed in the Chinese patent with the publication number CN217649131U, and will not be elaborated here.

[0039] The above description shows and describes several preferred embodiments of the present invention. However, as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the technology or knowledge in the relevant field. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
