Description

Technical Field

[0001] This utility model belongs to the field of pad printing machine technology, and in particular relates to a multi-station switching device. Background Technology

[0002] Chopsticks are a commonly used tool in daily life. They usually have a chopstick sleeve at the end (the part you hold). This sleeve increases the friction between your fingers and the chopsticks, making your grip more stable. It also serves as an indicator, helping users quickly distinguish between the head and tail of the chopsticks and avoid holding them upside down.

[0003] Currently, in order to improve the appearance of some chopsticks, different patterns are often printed on the chopstick sleeves to achieve a certain decorative effect and make the chopsticks more personalized.

[0004] In existing technologies, the printing of patterns on chopstick sleeves is usually done using pad printing machines, which can achieve automated production line production of feeding, printing, and unloading, reducing manual labor and improving production efficiency. However, existing pad printing machines can generally only perform single-sided printing on chopstick sleeves. For chopstick sleeves that require double-sided printing, the reverse side needs to be printed again after the first printing, which is cumbersome and consumes a lot of energy. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station switching device to address the aforementioned technical problems.

[0006] In view of this, the present invention provides a multi-station switching device, including a rotating platform, the rotating platform including a fixed part and a rotating part, and also including a plurality of material loading mechanisms and a plurality of flipping mechanisms. The plurality of material loading mechanisms are mounted in a ring array on the rotating part, and the plurality of flipping mechanisms are mounted in a ring array on the fixed part and are correspondingly arranged with the plurality of material loading mechanisms.

[0007] The material loading mechanism includes:

[0008] The housing is mounted on the rotating part;

[0009] Several material-carrying rods are rotatably mounted on the housing and arranged side by side for carrying chopstick sleeves;

[0010] Several transmission gears are respectively installed on each material carrier rod, and two adjacent transmission gears are meshed.

[0011] The control panel is connected to one of the material carrier bars;

[0012] The flipping mechanism is used to drive the control panel to rotate.

[0013] Furthermore, the flipping mechanism includes:

[0014] A fixed bracket is installed on the fixed part;

[0015] The pressure block is mounted on a fixed bracket in a height-adjustable manner;

[0016] The drive unit is mounted on a fixed bracket and is used to drive the pressure block to move up and down to drive the control disk to rotate.

[0017] Furthermore, the control panel also includes four fixed rods arranged in a circular array, and a pressure block is used to push one of the fixed rods to move.

[0018] The pressure block is also provided with an arc-shaped limiting groove. When the pressure block pushes one of the fixed rods to move, it will drive the control disk to rotate, thereby moving the adjacent fixed rod into the arc-shaped limiting groove.

[0019] Furthermore, the material loading mechanism also includes a locking assembly, which is disposed on the housing;

[0020] The control panel also has several positioning slots on its periphery, and the locking component is used to engage with one of the positioning slots.

[0021] Furthermore, the locking component includes:

[0022] A snap-fit ​​block is rotatably mounted on the housing for engaging with the positioning slot.

[0023] A reset element is located between the snap-fit ​​block and the housing, and is used for the rotational reset of the snap-fit ​​element.

[0024] Furthermore, the drive unit is a slide cylinder.

[0025] The beneficial effects of this utility model are:

[0026] As the material-carrying mechanism rotates and passes through the two printing stations in sequence, the flipping mechanism operates. The flipping mechanism drives the control panel to rotate, which in turn drives one of the material-carrying rods to rotate. Simultaneously, the transmission gears on the material-carrying rods rotate together, which in turn drives the other transmission gears to rotate, thus causing all the material-carrying rods to rotate. This allows all the chopstick sleeves mounted on the material-carrying rods to be flipped, enabling double-sided printing in one operation. This reduces production time and energy consumption, improves production efficiency, and is highly practical. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] Example 1:

[0034] This embodiment provides a multi-station switching device, including a rotating platform 1. The rotating platform 1 includes a fixed part 11 and a rotating part 12, and also includes a plurality of material loading mechanisms 2 and a plurality of flipping mechanisms 3. The plurality of material loading mechanisms 2 are arranged in a ring array on the rotating part 12, and the plurality of flipping mechanisms 3 are arranged in a ring array on the fixed part 11 and are correspondingly arranged with the plurality of material loading mechanisms 2.

[0035] Material loading mechanism 2 includes:

[0036] Housing 21, housing 21 is mounted on rotating part 12;

[0037] A plurality of material-carrying rods 22 are rotatably mounted on the housing 21 and arranged side by side for carrying chopstick sleeves;

[0038] A plurality of transmission gears 23 are respectively installed on each material carrier rod 22, and two adjacent transmission gears 23 are meshed together.

[0039] Control panel 24, which is connected to one of the material carrier rods 22;

[0040] The flipping mechanism 3 is used to drive the control disk 24 to rotate.

[0041] In this technical solution, the rotating platform 1 is a commercially available product. Its rotating part 12 is annular, and several material-carrying mechanisms 2 are fixedly installed on the rotating part 12. The number of material-carrying mechanisms 2 can be six, as shown in the figure. The six material-carrying mechanisms 2 are arranged on the rotating part 12 and rotate together with the rotating part 12. A loading station, two printing stations, and a unloading station are arranged on the outer side of the rotating platform 1, so that each material-carrying mechanism 2 can pass through the loading station, printing station, and unloading station in sequence, thereby realizing the automated printing operation of chopstick sleeve patterns.

[0042] As the material-carrying mechanism 2 rotates with the rotating part 12 and passes through the two printing stations in sequence, the flipping mechanism 3 operates. The flipping mechanism 3 drives the control disk 24 to rotate. While the control disk 24 rotates, it drives one of the material-carrying rods 22 to rotate. At the same time, the transmission gear 23 set on the material-carrying rod 22 rotates together. The rotation of the transmission gear 23 will drive the other transmission gears 23 to rotate together, so that all the material-carrying rods 22 rotate. This allows the chopstick sleeves mounted on the material-carrying rods 22 to be flipped, so as to meet the production operation of double-sided printing in one go, reduce production time, improve production efficiency, and have high practicality.

[0043] Example 2:

[0044] This embodiment provides a multi-station switching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] Furthermore, the flipping mechanism 3 includes:

[0046] Fixed bracket 31 is installed on fixed part 11;

[0047] Pressure block 32 is vertically mounted on fixed bracket 31;

[0048] The drive unit 33 is mounted on the fixed bracket 31 and is used to drive the pressure block 32 to move up and down to push the control disk 24 to rotate.

[0049] Furthermore, the control panel 24 also includes four fixed rods 25, which are arranged in a ring array, and the pressure block 32 is used to push one of the fixed rods 25 to move.

[0050] The pressure block 32 is also provided with an arc-shaped limiting groove 34. When the pressure block 32 pushes one of the fixed rods 25 to move, it will drive the control disk 24 to rotate, thereby moving the adjacent fixed rod 25 into the arc-shaped limiting groove 34.

[0051] Furthermore, the drive unit 33 is a slide cylinder.

[0052] In this technical solution, the drive unit 33 can be a pneumatic cylinder or an electric cylinder, or other drive components capable of lifting and moving the pressure block 32. Preferably, a sliding cylinder is used to integrate the drive function and high-precision guiding function, so as to achieve stable and reliable movement of the pressure block 32, while making the installation structure more compact and saving space.

[0053] When the slide cylinder controls the pressure block 32 to move down, the pressure block 32 first contacts the fixed rod 25 on the control disk 24. As the pressure block 32 continues to move down, the rotating part 12 of the rotating platform 1 also rotates, so that the pressure block 32 can push the fixed rod 25 to move and drive the control disk 24 to rotate, thereby realizing the rotation of the material carrier rod 22 so that the chopstick sleeve on the material carrier rod 22 can be printed on the reverse side.

[0054] When the pressure block 32 moves to the bottom, the control disk 24 rotates 90°. The adjacent fixed rod 25 moves to the position of the previous fixed rod 25 as the control disk 24 rotates, and abuts against the arc-shaped limiting groove 34 on the pressure block 32. This can play a certain limiting role, effectively preventing the material carrier rod 22 from rotating excessively and avoiding incorrect printing operations on the chopstick sleeve.

[0055] Then, as the rotating part 12 of the rotating platform 1 continues to rotate, the fixed rod 25 will disengage from the arc-shaped limiting groove 34 so as not to interfere with the pressure block 32. At the same time, the slide cylinder drives the pressure block 32 to rise and reset, in preparation for the next material loading mechanism 2 to perform a flipping operation.

[0056] Example 3:

[0057] This embodiment provides a multi-station switching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0058] Furthermore, the material loading mechanism 2 also includes a locking component, which is disposed on the housing 21;

[0059] The control panel 24 has several positioning slots 26 on its periphery, and the locking component is used to engage with one of the positioning slots 26.

[0060] Furthermore, the locking component includes:

[0061] The snap-fit ​​block 27 is rotatably mounted on the housing 21 and is used to snap-fit ​​with the positioning groove 26.

[0062] A reset element is disposed between the snap-fit ​​block 27 and the housing 21 and is used for the rotational reset of the snap-fit ​​element.

[0063] In this technical solution, there are four positioning slots 26, designed with an arc structure. These four positioning slots 26 are located on the periphery of the control panel 24, between two adjacent fixed rods 25. The locking block 27 is L-shaped, with one end rotatably mounted on the housing 21, and the other end having an arc structure that abuts against the positioning slot 26. When the control panel 24 rotates, the end of the locking block 27 moves along the shape of the positioning slot 26, thereby causing the locking block 27 to rotate around the connection point on the housing 21, while the reset element deforms. The reset element can be a spring or a torsion spring (not shown in the accompanying drawings), as long as it can achieve the rotational reset of the locking block 27. When the control panel 24 rotates 90°, the reset component returns to its shape and pushes the locking block 27 to rotate and reset, so that the end of the locking block 27 abuts against the next positioning groove 26, thereby locking and fixing the control panel 24, further limiting the excessive rotation of the control panel 24, preventing incorrect printing operations of the chopstick sleeve, effectively improving production reliability, and having high practicality.

[0064] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
