Description

Technical Field

[0001] The utility model relates to the field of screen printing equipment, in particular to a safety supporting mechanism of an oblique arm type screen printing machine. Background Art

[0002] The inclined arm screen printer is a machine that installs the printing head, scraper and other equipment on a rotatable bracket. The bracket is rotated to make the printing structure close to or away from the table to achieve printing and loading and unloading.

[0003] For example, the patent document with publication number CN212737442U discloses an oblique arm screen printer, including: a frame, a moving device and a printing device; the frame serves as the installation base of the moving device and the printing device, and the motor, air source and other large auxiliary equipment are all arranged inside the frame. The moving device is used to drive the printing device to move for screen printing. A through hole is provided on the top plate of the frame to allow the connection mechanism between the power source such as the motor and the air source and the moving device and the printing device to pass through.

[0004] For another example, the patent document with publication number CN210590967U discloses a manual screen printing machine, including a frame and a screen printing plate assembly pivotally connected to the frame, the frame including a screen printing platform, and the manual screen printing machine also includes a power device for driving the screen printing plate assembly to flip.

[0005] The above technologies all use a driving structure to support the frame. When the frame is raised for operations such as wiping the screen, it is easy to make the frame turn down due to misoperation, resulting in a safety accident. In addition, during the screen printing process, the risk of people approaching cannot be eliminated.

[0006] Therefore, a safety support mechanism for an inclined arm screen printing machine is proposed. Utility Model Content

[0009] As a further improvement of the above technical solution, the lifting member is a cylinder.

[0010] As a further improvement of the above technical solution, the lifting member is a cylinder.

[0011] As a further improvement of the above technical solution, it further includes a support rod rotatably installed on the top of the bracket. After the frame rotates and opens, the support rod can abut against the frame to support the frame.

[0012] As a further improvement of the above technical solution, a first sensor is provided on the bracket. The first sensor corresponds to the support rod, and the first sensor is electrically connected to the driving motor.

[0013] As a further improvement of the above technical solution, a photoelectric switch is provided on the bracket. The photoelectric switch is electrically connected to the lifting member.

[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0022] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] Reference Figures 1 to 3 A safety support mechanism for an oblique arm screen printer includes: a bracket 1, a frame 2 is rotatably mounted on the bracket 1, printing mechanisms such as a printing head and a scraper are all arranged on the frame 2, a printing table is arranged on the bracket 1, a swing arm 3 and a driving motor 4 are rotatably mounted on the bracket 1, the swing arm 3 is in transmission connection with the frame 2, and the driving motor 4 is used to drive the swing arm 3 to rotate; a lifting member 5 is arranged on the swing arm 3, and the top of the lifting member 5 is connected to the frame 2. When the driving motor 4 is started, the swing arm 3 can be driven to rotate, and the swing arm 3 can drive the frame 2 to rotate open or close through the lifting member 5. When operations such as wiping the screen are required, the lifting member 5 is raised to the longest position. In this position, the frame 2 cannot be rotated and closed, which can effectively ensure safety; on the contrary, when printing is required, the lifting member 5 is in a retracted state.

[0026] As a preferred embodiment, the lifting member 5 is an electrical component such as a cylinder or an oil cylinder that can be quickly extended and retracted, with fast response speed and strong support.

[0027] As a preferred embodiment, it also includes a support rod 6, which is rotatably mounted on the top of the bracket 1. When the frame 2 is rotated and opened, the support rod 6 can abut against the frame 2 to support the frame 2. The support rod 6 is manually controlled to further prevent the frame 2 from falling and causing safety accidents.

[0028] As a preferred embodiment, the bracket 1 is provided with a first sensor 7, the first sensor 7 corresponds to the support rod 6, and the first sensor 7 is electrically connected to the driving motor 4. When the support rod 6 is lowered, Figure 3As shown, the strut 6 is lapped on the first sensor 7. At this time, the first sensor 7 emits a signal to the controller to control the driving motor 4 from starting. This technology is the prior art and can prevent the frame 2 from falling due to misoperation.

[0029] As a preferred embodiment, a photoelectric switch 8 is provided on the bracket 1, and the photoelectric switch 8 is electrically connected to the lifting member 5. The photoelectric switch 8 forms an opposed area at the bracket 1. When a person approaches the opposed area, the photoelectric switch 8 controls the lifting member 5 to rise, thereby preventing the frame 2 from falling during operation. This can ensure that a person is at a relatively far distance from the equipment during operation, which can ensure the safety of the person on the one hand and protect the equipment on the other hand.

[0030] As a preferred embodiment, a guardrail 21 is provided on the frame 2, and a second sensor is provided on the guardrail 21. The second sensor is electrically connected to the lifting member 5. When a person touches the guardrail 21, the second sensor can control the lifting member 5 to rise, which can also ensure that a person is at a relatively far distance from the equipment during operation, ensuring the safety of the person on the one hand and protecting the equipment on the other hand.

[0031] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
