[0046] REFERENCE Figures 1 to 4 A printer capable of stable printing, comprising a horizontal support 1, a left support 2, a right support 3, a printing assembly 4, a horizontal moving driving part 5, a left sensing group 6 and a right sensing group 7.

[0047] The left support 2 is arranged on the left side of the horizontal support 1, and the right support 3 is arranged on the right side of the horizontal support 1.

[0048] The output end of the horizontal moving driving part 5 is in transmission connection with the printing assembly 4, and the horizontal moving driving part 5 is used for driving the printing assembly 4 to slide on the horizontal support 1.

[0049] The left sensing group 6 is arranged on the left support 2 and is used for sensing whether the printing assembly 4 moves to one side of the left support 2.

[0050] The right sensing group 7 is arranged on the right support 3 and is used for sensing whether the printing assembly 4 moves to one side of the right support 3.

[0051] The left sensing group 6 and the right sensing group 7 are in communication with the horizontal movement driving member 5, when the printing assembly 4 moves to one side of the left support 2 or the right support 3, the horizontal movement driving member 5 stops driving the printing assembly 4 or drives the printing assembly 4 to move reversely.

[0052] The working principle of the embodiment is as follows: the horizontal movement driving member 5 rotates forward to drive the printing assembly 4 to move towards the left support 2, when the printing assembly 4 moves to one side of the left support 2, the horizontal movement driving member 5 can stop driving the printing assembly 4, the printing assembly 4 can perform printing operation or take the state as the homing state of the printing assembly 4, or the horizontal movement driving member 5 reverses to drive the printing assembly 4 to move towards the right support 3 until the printing assembly 4 moves to one side of the right support 3.

[0053] It can be understood that the forward rotation and reverse rotation of the horizontal movement driving member 5 described above are only used to represent that the horizontal movement driving member 5 drives the printing assembly 4 to move to the opposite movement state; it can also be that when the horizontal movement driving member 5 reverses, the printing assembly 4 moves towards the right support 3, and when the horizontal movement driving member 5 rotates forward, the printing assembly 4 moves towards the left support 2.

[0054] The horizontal movement driving member 5 drives the printing assembly 4 to reciprocally move on the horizontal support 1, the left sensing group 6 and the right sensing group 7 are in communication with the horizontal movement driving member 5, when the printing assembly 4 moves to one side of the left support 2 or the right support 3, the horizontal movement driving member 5 stops driving the printing assembly 4 or drives the printing assembly 4 to move reversely, thereby avoiding the printing assembly 4 from colliding with the left support 2 or the right support 3 and causing the position of the printing assembly 4 to deviate, ensuring that the printing assembly 4 moves stably on the horizontal support 1, thereby ensuring good printing effect and printing quality.

[0055] Reference Figures 1 to 4 In an embodiment, the left support 2 is provided with a left slot 21, and the horizontal support 1 is installed on the left support 2 through the left slot 21;

[0056] Compared with the left end of the horizontal support 1 being directly connected to the left support 2, the horizontal support 1 in the embodiment is longer, and the moving distance of the printing assembly 4 on the horizontal support 1 is correspondingly longer, which can expand the printing range of the printing assembly 4;

[0057] The left sensing group 6 includes a left photoelectric sensor 61 and a left shielding member 62 arranged on the left side of the printing assembly 4, and the left photoelectric sensor 61 is arranged on the top of the left support 2;

[0058] When the printing assembly 4 moves towards the left support 2, the left shielding piece 62 moves synchronously until the left shielding piece 62 intersects with the left photoelectric sensor 61, and the transverse driving member 5 stops driving the printing assembly 4 to move or drives the printing assembly 4 to move reversely.

[0059] With reference to Figures 3 to 4 In an embodiment, the right sensing group 7 comprises a right photoelectric sensor 71 and a right shielding piece 72 arranged on the right side of the printing assembly 4.

[0060] The right photoelectric sensor 71 is arranged on the side of the right support 3 facing away from the left support 2.

[0061] The right support 3 is provided with a right slot 31 adjacent to the right photoelectric sensor 71, and the right slot 31 is used for the right shielding piece 72 to pass through.

[0062] When the printing assembly 4 moves towards the right support 3, the right shielding piece 72 moves synchronously until the right shielding piece 72 intersects with the right photoelectric sensor 71, and the transverse driving member 5 stops driving the printing assembly 4 to move or drives the printing assembly 4 to move reversely.

[0063] In the above structure, the right photoelectric sensor 71 is arranged on the side of the right support 3 facing away from the left support 2, and compared with the structure that the right photoelectric sensor 71 is arranged on the side of the right support 3 facing the left support 2, the moving distance of the printing assembly 4 in the former structure is longer, and the moving distance of the printing assembly 4 in the latter structure is shorter, so that the printing range of the printing assembly 4 can be further expanded.

[0064] With reference to Figures 3 to 4 In an embodiment, the right support 3 is provided with a mounting seat 32 on the top, and the fixed end of the transverse driving member 5 is fixed on the mounting seat 32.

[0065] In the above structure, the weight of the transverse support 1, the printing assembly 4, the left sensing group 6 and the right sensing group 7 is transmitted to the bearing object through the left support 2 and the right support 3, the mounting seat 32 is arranged on the top of the right support 3, and the right support 3 directly bears the gravity of the transverse driving member 5, so that the stress concentration point of the right support 3 is less, the compression resistance of the right support 3 is better, the stability of the printer is stronger, and the service life of the printer is longer.

[0066] With reference to Figures 3 to 6 Figures 3 to 6 In an embodiment, the transverse support 1 comprises a sliding rail 11, a transmission belt 12, a driving wheel 13 and a driven wheel 14.

[0067] The driving wheel 13 is fixedly connected with the output end of the transverse driving member 5.

[0069] One end of the slide rail 11 is fixed to the left support 2, and the other end is fixed to the right support 3.

[0070] The transmission belt 12 is engaged with the driving wheel 13 and the passive wheel 14, the printing assembly 4 is fixedly connected with the transmission belt 12, and is slidingly arranged on the slide rail 11.

[0071] The horizontal driving member 5 drives the driving wheel 13 to rotate, the driving wheel 13 drives the transmission belt 12 to rotate, the transmission belt 12 drives the passive wheel 14 to move synchronously, and the printing assembly 4 moves with the transmission belt 12, and the printing assembly 4 moves horizontally on the slide rail 11.

[0072] Specifically, the slide rail 11 is provided with a front groove 111 and a rear groove 112, and the transmission belt 12 is installed in the front groove 111 and the rear groove 112, so as to determine the movement path of the transmission belt 12, and avoid the transmission belt 12 from being separated from the driving wheel 13 and the passive wheel 14, thereby affecting the stability of driving the printing assembly 4 to move.

[0073] Specifically, the printing assembly 4 is provided with an upper pulley 411 and a lower pulley 412 on the rear side, the slide rail 11 further includes an upper groove 113 and a lower groove 114, the upper pulley 411 is slidingly arranged in the upper groove 113, and the lower pulley 412 is slidingly arranged in the lower groove 114. The upper pulley 411 and the lower pulley 412 clamp the slide rail 11, so as to reduce the probability of the upper pulley 411 and the lower pulley 412 being separated from the slide rail 11; when the printing assembly 4 is printing, the printing assembly 4 is subjected to an upward thrust, and at this time, the lower pulley 412 is prevented from being separated from the lower groove 114 due to the abutment between the lower pulley 412 and the inner wall of the lower groove 114, thereby further improving the stability of the printing assembly 4 during movement and printing.

[0074] More specifically, the upper pulley 411 is two or more, and the lower pulley 412 is two or more. The printing assembly 4 has more support points on the slide rail 11, and has stronger stability during movement and printing.

[0075] In an embodiment, the printing assembly 4 includes a lifting driving member 41 and a printing head 42, a fixed end of the lifting driving member 41 is slidingly arranged on the horizontal support 1, and an output end of the lifting driving member 41 is in transmission connection with the printing head 42.

[0076] When the horizontal driving member 5 drives the printing assembly 4 to move to a printing position, the printing head 42 is lowered to perform a printing operation.

[0077] Specifically, the lifting driving part 41 is provided with a lifting sensing part 413, and the printing head 42 is provided with a lifting sensing matching part 423 matched with the lifting sensing part 413; the lifting sensing part 413 is in communication with the lifting driving part 41.

[0078] When the lifting driving part 41 drives the printing assembly 4 to rise to a certain height, the lifting sensing part 413 senses the lifting sensing matching part 423, thereby sending an identification signal to the lifting driving part 41, and the lifting driving part 41 stops driving the printing head 42 to rise, thereby avoiding the printing head 42 from being excessively lifted to collide with other components.

[0079] The above is a specific description of the preferred embodiment of the utility model, but the utility model is not limited to the embodiment, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the application.
