Description

Technical Field

[0001] The utility model belongs to the technical field of inkjet printing, in particular to a bidirectional anti-collision device for an inkjet carriage. Background Art

[0002] An inkjet printer is a non-contact printing mechanism. When the printer is in operation, the inkjet carriage on the printer prints the printed material with ink. At the printing site, other printed materials or other foreign objects may fall onto the printed material. Therefore, when the inkjet carriage moves to the foreign object, the inkjet carriage's printhead can easily be damaged when it encounters the foreign object, causing significant economic losses. Numerous anti-collision structures for inkjet carriages are currently available on the market. For example, application number 202222431790.1 discloses an anti-collision mechanism for a printing carriage and a printing device. This structure includes an anti-collision member and a connector. A trigger triggers a corresponding microswitch to send a shutdown signal. This structure is relatively simple, but when the anti-collision member is knocked to one side and swings back, it will swing back at a relatively high speed. Therefore, after avoiding the foreign object, the anti-collision member itself will swing back at a relatively high speed, causing a certain degree of impact on the printhead. Over time, the printhead may also be damaged, affecting the service life of the inkjet carriage's printhead. Utility Model Content

[0003] The purpose of the utility model is to provide a bidirectional anti-collision device for an inkjet carriage that can solve at least one of the above problems.

[0004] According to one aspect of the utility model, a bidirectional anti-collision device for an inkjet carriage is provided, comprising an anti-collision rod, an anti-collision mounting plate, a microswitch, a microswitch mounting plate, a microswitch pressure plate and a spring device, the microswitch mounting plate being fixed at both ends of the anti-collision mounting plate, the microswitch being fixed on the microswitch mounting plate, the spring device being mounted on the microswitch mounting plate through the microswitch pressure plate, the microswitch pressure plate being rotatably connected to the microswitch mounting plate, the bottom end of the microswitch pressure plate being connected to the anti-collision rod, the microswitch comprising a roller, and the roller and the microswitch pressure plate being correspondingly arranged.

[0005] The beneficial effect of the present invention is that when the anti-collision bar hits a foreign object and swings, the anti-collision bar drives the microswitch pressure plate to swing, so that the microswitch pressure plate touches the roller of the microswitch, thereby triggering a stop signal, and the microswitch sends a signal to an external controller, which is convenient for controlling the inkjet carriage to stop moving and play an anti-collision role; at the same time, by providing a spring device, the microswitch pressure plate can be reset, thereby driving the anti-collision bar to reset to the center, avoiding the anti-collision bar from swinging repeatedly, and avoiding the anti-collision bar from colliding with the inkjet carriage nozzle when swinging in the opposite direction, further protecting the inkjet carriage, thereby effectively ensuring the service life of the inkjet carriage nozzle.

[0006] In some embodiments, the micro switch is fixed to the upper portion of the micro switch mounting plate, the lower portion of the micro switch mounting plate is provided with a protrusion, and the spring device is provided corresponding to the protrusion and is located below the micro switch. Thus, by providing the protrusion, the spring device can be installed in a limited position.

[0007] In some embodiments, the spring device includes a first fixing plate, a second fixing plate, and a spring. The first fixing plate and the second fixing plate are respectively disposed on either side of the protrusion and abut against the corresponding sides of the protrusion. One end of the spring is fixed to the first fixing plate, and the other end is fixed to the second fixing plate. The first fixing plate and the second fixing plate are both located between the microswitch mounting plate and the microswitch pressure plate. Thus, the first and second fixing plates facilitate the installation of the spring, and the protrusion can also limit the position of the first and second fixing plates.

[0008] In some embodiments, the bidirectional anti-collision device for the inkjet carriage further includes a plug screw, one end of which is located outside the microswitch pressure plate, and the other end of which passes through the microswitch pressure plate, the first fixing plate, and the second fixing plate, and is connected to the microswitch mounting plate. Thus, the plug screw facilitates the rotation of the microswitch pressure plate, the first fixing plate, and the second fixing plate relative to the microswitch mounting plate.

[0009] In some embodiments, a bidirectional anti-collision device for an inkjet carriage further includes a vertical rod, the anti-collision rod being connected to the micro-switch pressure plate via the vertical rod, the top end of the vertical rod being fixed to the bottom end of the micro-switch pressure plate, and the bottom end of the vertical rod being fixed to the anti-collision rod. Thus, the provision of the vertical rod facilitates the connection of the anti-collision rod and the micro-switch pressure plate to form a single unit, achieving synchronous swing.

[0010] In some embodiments, a groove is provided on the top of the micro switch pressure plate, and the roller of the micro switch is located in the groove, so that when the micro switch pressure plate swings, the side wall of the groove interacts with the roller of the micro switch to trigger the micro switch.

[0011] In some embodiments, a first limiting rod is provided on the front side of the first fixing plate, a second limiting rod is provided on the front side of the second fixing plate, and the micro switch pressure plate is located between the first limiting rod and the second limiting rod. This allows the relative position of the micro switch pressure plate to be determined, facilitating installation.

Thus, by installing the mounting ears, the entire structure can be easily installed on the inkjet carriage. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Reference Figures 1 and 2 A bidirectional anti-collision device for an inkjet carriage includes an anti-collision rod 1, an anti-collision mounting plate 2, a microswitch 3, a microswitch mounting plate 4, a microswitch pressure plate 5, and a spring device 6. The microswitch mounting plate 4 is fixed to both ends of the anti-collision mounting plate 2 by screws. The microswitch 3 is fixed to the microswitch mounting plate 4. The spring device 6 is mounted on the microswitch mounting plate 4 via the microswitch pressure plate 5. The microswitch pressure plate 5 is rotatably connected to the microswitch mounting plate 4. The bottom end of the microswitch pressure plate 5 is connected to the anti-collision rod 1. The microswitch 3 includes a roller 31, which is correspondingly arranged in the microswitch pressure plate 5.

[0018] The utility model of the inkjet carriage bidirectional anti-collision device is installed on both sides of the inkjet carriage when in use (such as Figure 3 As shown in FIG, when the anti-collision bar 1 on one side of the inkjet carriage collides with a foreign object, the micro switch 3 can be triggered. The micro switch 3 is electrically connected to an external controller via a wire. When the micro switch 3 is triggered, a signal is sent to the external controller, which can control the inkjet carriage to stop and prevent the inkjet carriage from colliding with foreign objects.

[0019] Specifically, when the anti-collision bar 1 collides with a foreign object, the anti-collision bar 1 swings, thereby driving the microswitch pressure plate 5 to swing together, and the microswitch pressure plate 5 touches the roller of the microswitch 3, thereby triggering a stop signal, which facilitates the inkjet carriage to stop moving in time and protects the inkjet carriage's nozzle; finally, the microswitch pressure plate 5 is pulled back to the center by the spring device 6, and the anti-collision bar 1 is reset at the same time. At this time, the microswitch pressure plate 5 is not in contact with the roller of the microswitch 3.

[0020] The micro switch 3 is fixed to the upper part of the micro switch mounting plate 4. The lower part of the micro switch mounting plate 4 is provided with a protrusion 41. The spring device 6 is provided corresponding to the protrusion 41 and is located below the micro switch 3. Among them, the protrusion 41 and the micro switch mounting plate 4 are an integrally formed structure.

[0021] The spring device 6 includes a first fixing plate 61, a second fixing plate 62 and a spring 63. The first fixing plate 61 and the second fixing plate 62 are respectively arranged on both sides of the protrusion 41 and abut against the corresponding sides of the protrusion 41. One end of the spring 63 is fixed on the first fixing plate 61, and the other end is fixed on the second fixing plate 62. The spring 63 is located below the protrusion 41; the first fixing plate 61 and the second fixing plate 62 are both located between the microswitch mounting plate 4 and the microswitch pressure plate 5.

[0022] The bidirectional anti-collision device for an inkjet carriage according to the present invention further includes a jackscrew 7. One end of the jackscrew 7 is located outside the microswitch pressure plate 5, and the other end passes through the microswitch pressure plate 5, the first fixing plate 61, and the second fixing plate 62, and is connected to the microswitch mounting plate 4. The jackscrew 7 facilitates the rotation of the microswitch pressure plate 5, the first fixing plate 61, and the second fixing plate 62 around the jackscrew 7.

[0023] A bidirectional anti-collision device for an inkjet carriage also includes a vertical rod 8. The anti-collision bar 1 is connected to the microswitch pressure plate 5 via the vertical rod 8. The top end of the vertical rod 8 is fixed to the bottom end of the microswitch pressure plate 5, and the bottom end of the vertical rod 8 is fixed to the anti-collision bar 1. Both ends of the vertical rod 8 can be screwed or welded to the corresponding structure. By providing the vertical rod 8, the anti-collision bar 1 and the microswitch pressure plate 5 can form a whole, so that when the anti-collision bar 1 swings, it drives the microswitch pressure plate 5 to achieve synchronous swinging.

[0024] A groove 51 is formed at the top of the microswitch pressure plate 5, and the roller 31 of the microswitch 3 is located in the groove 51. When the microswitch pressure plate 5 is in the center position, the inner wall of the groove 51 and the roller 31 are separated. When the anti-collision bar 1 hits an obstacle and drives the microswitch pressure plate 5 to swing, the side wall of the groove 51 contacts the roller 31 of the microswitch 3, triggering the microswitch 3.

[0025] A first limiting rod 611 is provided on the front side of the first fixing plate 61 , a second limiting rod 621 is provided on the front side of the second fixing plate 62 , and the micro switch pressing plate 5 is located between the first limiting rod 611 and the second limiting rod 621 .

[0026] Therefore, when the anti-collision bar 1 encounters a foreign object on the side of the first fixed plate 61 during the movement of the inkjet carriage, the anti-collision bar 1 swings toward the side of the second fixed plate 62, and the anti-collision bar 1 drives the micro-switch pressure plate 5 to swing together; the micro-switch pressure plate 5 acts on the second limiting rod 621, causing the second fixed plate 62 to swing; when the second fixed plate 62 swings, it pulls the spring 63, causing the spring 63 to be in a stretched state. Under the action of the protrusion 41, the first fixed plate 61 is limited so that the first fixed plate 61 does not swing. As the micro-switch pressure plate 5 swings, the side wall of the groove 51 touches the roller 31 of the micro-switch, and the micro-switch 3 is triggered, sending a stop signal, which helps the inkjet carriage to stop and prevents the inkjet carriage's nozzle from being damaged by foreign objects. When the foreign object obstacle is eliminated, under the action of the rebound force of the spring 63, the second fixed plate 62 is pulled to reset, so that the second limit rod 621 pushes the microswitch pressure plate 5 to reset, and the microswitch pressure plate 5 drives the anti-collision rod 1 to reset, realizing centering reset. At this time, the roller 31 of the microswitch 3 and the groove 51 are in a non-contact state.

[0027] Similarly, when the anti-collision bar 1 encounters a foreign object on the side of the second fixed plate 62 during the movement of the inkjet carriage, it swings in the opposite direction, driving the microswitch pressure plate 5 to swing in the opposite direction, contacting the microswitch and achieving a two-way anti-collision function. At this time, the second fixed plate 62 remains stationary, while the first fixed plate 61 swings, pulling the spring 63 to stretch. When the foreign object obstacle is removed, the spring 63 drives the first fixed plate 61, the microswitch pressure plate 5, and the anti-collision bar 1 to reset.

[0028] Both ends of the anti-collision mounting plate 2 are integrally formed or welded with mounting ears 21, and the mounting ears 21 are provided with mounting holes 211. Through the mounting holes 211, the anti-collision mounting plate 2 can be conveniently fixed to the inkjet carriage by screws passing through the mounting holes 211, making it convenient to install the entire structure.

[0029] The above are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
