Description

Technical Field

[0001] The utility model belongs to the technical field of digital printing, and in particular relates to an anti-collision structure of a printing carriage. Background Art

[0002] When the printing carriage of the existing digital printing equipment moves back and forth along the guide beam to scan and spray ink, in order to avoid obstacles on the printing medium or collision of the printing carriage's nozzle with the warping, damage, or fabric thread ends of the medium and the nozzle, thereby causing damage to the nozzle, an anti-collision structure is usually set on the outer side surfaces of the printing carriage on both sides of its moving direction. However, the existing installation structure makes the distance between the anti-collision bar and the printing carriage too close. After the anti-collision bar hits an obstacle, when the control board receives the instruction and controls the carriage to stop printing, the printing carriage cannot stop in time because the speed of the printing carriage is too fast. Therefore, there is still a risk of the nozzle colliding with the obstacle, thereby causing damage to the nozzle. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 2The embodiment of the present invention provides an anti-collision structure for a printing carriage, comprising an extension seat 1, a fixed seat 2, an anti-collision strip 3, an elastic member 4 and an anti-collision switch 5. The extension seat 1 is used to be arranged on the outer side of the moving direction of the printing carriage 10, specifically, it is arranged on the opposite sides of the moving direction of the printing carriage 10, so that the printing carriage can be protected from collision when it moves back and forth. The fixed seat 2 is installed on the side of the extension seat 1 away from the printing carriage 10. The extension seat 1 provides an extension space between the fixed seat 2 and the printing carriage 10. The anti-collision strip 3 is rotatably arranged on the side of the fixed seat 2 away from the extension seat 1. The bottom of the anti-collision strip 3 on the side away from the fixed seat 2 can rotate toward the fixed seat 2 when it is subjected to force, that is, when the printing carriage is in motion, the anti-collision strip 3 can rotate toward the fixed seat 2 when it is in motion. When the trolley 10 moves back and forth, the bottom of the anti-collision bar 3 will rotate toward the fixed seat 2 when it touches an obstacle. The elastic member 4 is provided on the fixed seat 2 and provides a pre-tightening force to the anti-collision bar 3 to return to its original position after rotation, thereby resetting the anti-collision bar. The anti-collision switch 5 is used to be electrically connected to the control panel of the printing trolley 10 and is provided on the fixed seat 2. When the anti-collision bar 3 rotates, the anti-collision switch sends a collision signal to the control panel to enable the control panel to control the printing trolley to stop moving, thereby protecting the print head of the printing trolley and preventing the print head from touching an obstacle and being damaged.

[0030] By setting an extension seat 1 to increase the distance between the anti-collision strip 3 and the side of the printing carriage 10, there is an extension space between the fixed seat 2 and the side of the printing carriage 10, thereby extending the distance between the anti-collision strip 3 and the nozzle on the printing carriage 10, and providing an effective running stroke for the period from when the control panel of the printing carriage 10 receives the collision command to when the printing carriage 10 is controlled to stop, which can effectively avoid the collision of the nozzle with the obstacle and thus damage the nozzle.

[0031] The anti-collision structure of the printing carriage provided in the embodiment of the utility model can effectively prevent the print head from colliding with obstacles and causing damage to the print head.

[0032] It should be noted that, perpendicular to the moving direction of the printing carriage 10, the two ends of the anti-collision strip 3 are arranged flush with the printing carriage 10, so that the anti-collision strip 3 can cover the entire printing carriage 10, thereby better protecting the printing carriage 10 from collision. The bottom of the anti-collision strip 3 is flush with the bottom of the printing carriage 10 or slightly lower than the printing carriage 10, so that the anti-collision strip 3 can better contact the obstacle in the moving direction of the printing carriage 10, thereby protecting the printing carriage 10 from collision.

[0033] Furthermore, the extension seat 1 is an L-shaped structure, which can reduce the weight of the extension seat 1 to avoid increasing the weight of the printing carriage 10. The extension seat 1 is provided with a number of reinforcing ribs at intervals perpendicular to the moving direction of the printing carriage 10. The reinforcing ribs are used to increase the strength of the extension seat 1. The reinforcing ribs include a mounting rod 111 extending upward toward one end of the fixed seat 2. The fixed seat 2 is fixed to the mounting rod 111. By providing the mounting rod 111 to connect with the fixed seat 2, the connection area of ​​the extension seat 1 and the installation side of the fixed seat 2 can be increased, thereby making the connection between the extension seat 1 and the fixed seat 2 more stable.

[0034] Specifically, perpendicular to the moving direction of the printing carriage 10, both ends of the extension seat 1 and both ends of the fixed seat 2 are arranged flush with the surface of the printing carriage 10, so that the extension seat 1 and the fixed seat 2 can better support the anti-collision bar 3. When the anti-collision bar 3 touches an obstacle, it can effectively avoid the anti-collision bar 3 from deforming at different positions, thereby affecting the anti-collision protection of the printing carriage 10.

[0035] See also Figure 2-Figure 3 Furthermore, a first protrusion 21 is provided on the side of the fixing base 2 facing away from the extension base 1, and a connecting portion 31 is provided on the side of the anti-collision strip 3 facing the fixing base 2. The first protrusion 21 and the connecting portion 31 are rotatably connected. By providing the first protrusion 21 and the connecting portion 31 with a rotatable connection, a gap can be provided between the anti-collision strip 3 and the fixing base 2 when the anti-collision strip 3 is installed on the fixing base 2, thereby providing space for the anti-collision strip 3 to rotate around its connection with the fixing base 2.

[0036] See also Figure 3 Furthermore, the anti-collision strip 3 is provided with a limiting portion 32 above the connecting portion 31. The limiting portion 32 abuts against the first protrusion 21, and the elastic member 4 provides a pre-tightening force to the limiting portion 32 against the first protrusion 21. In this way, the elastic member 4 provides a pre-tightening force to the limiting portion 32 against the first protrusion 21, pulling the first protrusion 21 toward the first protrusion 21. The first protrusion 21 generates an abutting force on the limiting portion 32. The forces applied to the limiting portion 32 in two directions can keep the anti-collision strip 3 stationary and prevent the anti-collision strip 3 from rotating.

[0037] See also Figure 3 Furthermore, the elastic member 4 is a tension spring, a first connecting hole 221 is provided on the fixing seat 2, and a second connecting hole 321 is provided on the limiting portion 32. The two ends of the elastic member 4 are hooked on the first connecting hole 221 and the second connecting hole 321. The provision of the first connecting hole 221 and the second connecting hole 321 facilitates the installation of the elastic member 4 and is easy to install.

[0038] See also Figure 3Furthermore, the fixing base 2 is provided with a second protrusion 22 below the limiting portion 32, and the first connection hole 221 is provided on the second protrusion 22. The second protrusion 22 extends outside the fixing base 2, so that the second protrusion 22 and the limiting portion 32 correspond to each other vertically, which can shorten the installation distance when the elastic member 4 is connected to the fixing base 2 and the anti-collision strip 3, and more conveniently install the elastic member 4.

[0039] See also Figure 4-Figure 5 Furthermore, the anti-collision switch 5 includes a trigger plate 51. The anti-collision switch 5 is fixed to the fixed base 2. The trigger plate 51 is located below the limit portion 32 and is pressed by the limit portion 32. When the bottom of the anti-collision bar 3 rotates toward the fixed base 2, the limit portion 32 moves away from the trigger plate 51, the trigger plate 51 resets, and the anti-collision switch 5 sends a collision signal to the control board. Because the trigger plate 51 of the anti-collision switch 5 abuts the limit portion 32, when the anti-collision bar 3 hits an obstacle, the bottom rotates toward the fixed base 2, causing the limit portion 32 to disengage from the trigger plate 51, the trigger plate 51 resets, and thus generates a signal. The anti-collision switch 5 sends this signal to the control board, which can then control the printing carriage 10 to stop moving.

[0040] See also Figure 6 Specifically, the fixing base 2 includes a plate-shaped main body 2a and sidewalls 2b disposed on opposite sides of the main body 2a. The main body 2a is connected and fixed to the extension base 1. First protrusions 21 are disposed on each of the sidewalls 2b, and the connecting portion 31 corresponds to the first protrusions 21. By disposing the first protrusion 21 and the connecting portion 31, which connect the fixing base 2 and the anti-collision strip 3, at the ends of the fixing base 2 and the anti-collision strip 3, the anti-collision strip 3 can be installed more securely. At the same time, the central portion of the fixing base 2 can be configured as a hollow structure, thereby reducing the weight and material cost of the fixing base 2.

[0041] See also Figure 6 Specifically, a strip hole 2a1 is provided on the main body 2a, and the connecting piece passes through the strip hole 2a1 and is fixed to the mounting seat, thereby realizing the installation and fixation of the fixing seat 2 and the extension seat 1.

[0042] See also Figure 3 、 Figure 5Furthermore, the anti-collision switch 5 is provided on one side wall 2b, with the trigger plate 51 contacting the limit portion 32, namely, the limit portion 32 above the connection portion 31 corresponding to the first protrusion 21 on the side wall 2b. The elastic member 4 is provided on the other side wall 2b, with its ends respectively connected to the side wall 2b and the limit portion 32. Specifically, one end of the elastic member is connected to the limit portion 32 above the connection portion 31 corresponding to the first protrusion 21 on the side wall 2b, and the second protrusion 22 is provided on the side wall 2b. In this way, the two side walls 2b can be rationally and effectively utilized to install the anti-collision switch 5 and the elastic member 4, eliminating the need to provide additional structures on the fixing base for mounting the anti-collision switch 5 and the elastic member 4, thereby improving the rational utilization of space.

[0043] It should be noted that the limiting portion 32 on the anti-collision strip 3 can be a partition setting, that is, the limiting portion is correspondingly arranged above each connecting portion, and the limiting portion 32 can also be continuously arranged, that is, extending from the connecting portion 31 at one end of the anti-collision strip 3 to the connecting portion 31 at the other end.

[0044] Specifically, the bottom edge of the anti-collision strip 3 is serrated. The serrated anti-collision strip 3 can better contact obstacles on the printing medium, such as but not limited to small burrs, small thread ends, etc. on the printing medium, so that the anti-collision strip 3 has a higher detection rate for obstacles.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
