Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to an anti-deflection guide bracket for printers. Background Technology

[0002] A printer is an electronic device primarily used to output text, images, and other information from a computer or other digital device onto physical media such as paper or film. Printers are an important output device for computers and are widely used in industries such as office, education, and advertising.

[0003] The printhead of a printer is usually constrained by a guide bracket to keep it on a straight path during movement. However, traditional guide brackets only provide unidirectional constraint and are difficult to resist Y-axis deflection force. During high-speed movement, lateral deflection is likely to occur, causing the printhead to deflect or tilt laterally, resulting in blurry or misaligned printed content. Moreover, plastic guide rails are prone to wear, leading to increased gaps and affecting printing accuracy and quality. Therefore, we propose an anti-deflection guide bracket for printers. Utility Model Content

[0004] The purpose of this invention is to provide an anti-deflection guide bracket for printers, so as to solve the problem mentioned in the background art that the print head is prone to lateral deflection, resulting in lateral deflection or skewness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printer anti-deflection guide bracket, comprising a guide bracket body, an upper guide slider sleeved on the outside of the guide bracket body, and a lower guide slider disposed below the upper guide slider; inclined surfaces are provided on the outer walls of both sides of the guide bracket body; a first guide roller is installed on the top of the upper guide slider, and second guide rollers are installed on both sides inside the upper guide slider; a counterweight structure is provided at the bottom of the lower guide slider, the counterweight structure comprising a spherical sleeve, a universal ball, and a counterweight block; a lower bracket is fixed below the lower guide slider, and a mounting base is fixed at the bottom of the lower bracket; a printer head is disposed inside the mounting base.

[0006] Preferably, upper positioning plates are fixed on the outer walls of both sides of the upper guide slider, and lower positioning plates are fixed on the outer wall of the lower guide slider below the upper positioning plates, and the upper positioning plates and the lower positioning plates are connected by fastening bolts.

[0007] Preferably, the top end and the inclined surface of the guide bracket body are provided with strip grooves, and friction pads are adhered inside the strip grooves. The first guide roller and the second guide roller are closely fitted with the friction pads, which improves the gripping force of the guide bracket body surface.

[0008] Preferably, the spherical sleeve is fixed at the center of the bottom end of the lower guide slider, the universal ball is disposed inside the spherical sleeve, and the counterweight is installed at the bottom end of the universal ball.

[0009] Preferably, the top of the mounting base is provided with a through groove, and the two sides inside the mounting base are provided with storage grooves. A bidirectional lead screw is installed inside the through groove, and threaded sliders are fitted on the outer walls on both sides of the bidirectional lead screw, and the threaded sliders are threadedly engaged with the bidirectional lead screw.

[0010] Preferably, the storage slot is provided with a positioning block inside, and the top of the positioning block is fixedly connected to the threaded slider.

[0011] Preferably, positioning slots are provided on the two outer side walls of the top of the printer head, and the positioning blocks are tightly engaged with the positioning slots, which improves the ease of disassembling the printer head.

[0012] Preferably, one end of the bidirectional lead screw extends to the outside of the mounting base and is fixed with a knob, and a damping sleeve is fixed on the outer wall of the mounting base outside the knob. The inner wall of the damping sleeve is in close contact with the outer wall of the knob, which facilitates the rotation of the bidirectional lead screw. The damping sleeve can prevent the knob from becoming loose.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting 45-degree inclined surfaces on both sides of the guide bracket body, the upper guide slider is sleeved on the outside of the guide bracket body. The upper guide slider and the lower guide slider are fixed as a whole by fastening bolts. The printer head is installed at the bottom of the lower bracket below the lower guide slider and is fixed in the mounting base. When the external drive component drives the upper guide slider to translate along the X-axis, the upper guide slider slides along the guide bracket body. At this time, the inclined structure of the inclined surface naturally resists the Y-axis deflection force, thereby solving the problem of easy deflection of the existing guide bracket.

[0015] By setting a counterweight structure below the lower guide slider, the counterweight structure consists of a spherical sleeve, a universal ball, and a counterweight block. The counterweight block rotates inside the spherical sleeve through the universal ball. The counterweight block provides a vertical downward pulling force through the spherical sleeve and the universal ball, causing the upper guide slider to automatically move downward as it wears to compensate for the gap, thus realizing a mechanical self-correction function. The first and second guide rollers inside the upper guide slider contact the friction plates and roll along the surface of the guide bracket body, constraining the movement direction of the upper guide slider and improving the smoothness of the upper guide slider. The friction plates inside the strip groove improve the gripping force on the surface of the guide bracket body. This design relies entirely on the mechanical structure to achieve the anti-deviation function and can achieve zero power consumption operation. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5An embodiment of the present invention provides: a printer anti-deflection guide bracket, including a guide bracket body 1, an upper guide slider 2 sleeved on the outside of the guide bracket body 1, and a lower guide slider 3 provided below the upper guide slider 2, inclined surfaces 13 provided on the outer walls on both sides of the guide bracket body 1, a first guide roller 8 installed on the top of the upper guide slider 2, and a second guide roller 9 installed on both sides inside the upper guide slider 2.

[0025] Specifically, see the attached document. Figure 1-3 The guide bracket body 1 has 45-degree inclined surfaces 13 on both sides. The upper guide slider 2 is sleeved on the outside of the guide bracket body 1. The upper guide slider 2 and the lower guide slider 3 are fixed together as a whole by fastening bolts 12. The printer head 7 is installed at the bottom of the lower bracket 5 below the lower guide slider 3. The printer head 7 is fixed in the mounting base 6. When the external drive component drives the upper guide slider 2 to translate along the X-axis, the upper guide slider 2 slides along the guide bracket body 1. At this time, the inclined structure of the inclined surface 13 naturally resists the Y-axis deflection force, thereby solving the problem of easy deflection of the existing guide bracket.

[0026] The bottom end of the lower guide slider 3 is provided with a counterweight structure 4, which includes a spherical sleeve 14, a universal ball 15 and a counterweight block 16.

[0027] Specifically, see the attached document. Figure 4 Because a counterweight structure 4 is provided below the lower guide slider 3, the counterweight structure 4 consists of a spherical sleeve 14, a universal ball 15 and a counterweight block 16. The counterweight block 16 rotates inside the spherical sleeve 14 through the universal ball 15. The counterweight block 16 provides a vertical downward pulling force through the spherical sleeve 14 and the universal ball 15, so that the upper guide slider 2 automatically moves down to compensate for the gap as it wears, thereby realizing the mechanical self-correction function.

[0028] A lower bracket 5 is fixed below the lower guide slider 3, and a mounting base 6 is fixed at the bottom of the lower bracket 5. The printer head 7 is installed inside the mounting base 6.

[0029] Upper positioning pieces 10 are fixed on the outer walls of both sides of the upper guide slider 2, and lower positioning pieces 11 are fixed on the outer wall of the lower guide slider 3 below the upper positioning pieces 10. The upper positioning pieces 10 and the lower positioning pieces 11 are connected by fastening bolts 12.

[0030] The top end of the guide bracket body 1 and the surface of the inclined surface 13 are both provided with strip grooves 101, and friction plates 102 are adhered inside the strip grooves 101. The first guide roller 8 and the second guide roller 9 are both in close contact with the friction plates 102.

[0031] Reference Appendix Figure 3The first guide roller 8 and the second guide roller 9 inside the upper guide slider 2 contact the friction plate 102 and roll along the surface of the guide bracket body 1, constraining the movement direction of the upper guide slider 2 and improving the smoothness of the upper guide slider 2. The setting of the friction plate 102 inside the strip groove 101 improves the gripping force on the surface of the guide bracket body 1. This design relies entirely on the mechanical structure to achieve the anti-deviation function and can achieve zero power consumption operation.

[0032] The spherical sleeve 14 is fixed at the center of the bottom end of the lower guide slider 3, the universal ball 15 is set inside the spherical sleeve 14, and the counterweight 16 is installed at the bottom end of the universal ball 15.

[0033] The top of the mounting base 6 is provided with a through groove 601, and the two sides inside the mounting base 6 are provided with storage grooves 602. A two-way lead screw 17 is installed inside the through groove 601, and threaded sliders 18 are fitted on the outer walls on both sides of the two-way lead screw 17. The threaded sliders 18 are threadedly engaged with the two-way lead screw 17.

[0034] The storage slot 602 is equipped with a positioning block 19 inside, and the top of the positioning block 19 is fixedly connected to the threaded slider 18.

[0035] The printer head 7 has two outer side walls at the top of the positioning slots 22, and the positioning block 19 is tightly engaged with the positioning slots 22.

[0036] One end of the bidirectional lead screw 17 extends to the outside of the mounting base 6 and is fixed with a knob 20. A damping sleeve 21 is fixed on the outer wall of the mounting base 6 outside the knob 20. The inner wall of the damping sleeve 21 is in close contact with the outer wall of the knob 20.

[0037] Specifically, see the attached document. Figure 5 When disassembling the printer head 7, rotating the knob 20 causes the bidirectional lead screw 17 to rotate, which causes the threaded slider 18 to move the positioning block 19 out of the positioning slot 22. Then, pulling down the printer head 7 will remove it from the mounting base 6, thereby improving the ease of disassembling the printer head 7.

[0038] In this embodiment, the following steps are taken: First, the guide bracket body 1 has 45-degree inclined surfaces 13 on both sides. The upper guide slider 2 is sleeved on the outside of the guide bracket body 1. The upper guide slider 2 and the lower guide slider 3 are fixed together as a whole by fastening bolts 12. The printer head 7 is installed at the bottom of the lower bracket 5 below the lower guide slider 3 and is fixed in the mounting base 6. When the external drive unit drives the upper guide slider 2 to translate along the X-axis, the upper guide slider 2 slides along the guide bracket body 1. At this time, the inclined structure of the inclined surface 13 naturally resists the Y-axis deflection force, thereby solving the problem of easy deflection of the existing guide bracket. Then, since a counterweight structure 4 is provided below the lower guide slider 3, the counterweight structure 4 is composed of a spherical sleeve 14, a universal ball 15, and a counterweight block 16. The counterweight block 16 rotates inside the spherical sleeve 14 through the universal ball 15. The counterweight block 16 rotates through the spherical sleeve 14 and the universal ball 15. The ball 15 always provides a vertical downward pulling force, causing the upper guide slider 2 to automatically move downward as it wears to compensate for the gap, thereby realizing the mechanical self-correction function. The first guide roller 8 and the second guide roller 9 inside the upper guide slider 2 contact the friction plate 102 and roll along the surface of the guide bracket body 1, constraining the movement direction of the upper guide slider 2 and improving the smoothness of the upper guide slider 2. The setting of the friction plate 102 inside the strip groove 101 improves the gripping force on the surface of the guide bracket body 1. This design relies entirely on the mechanical structure to achieve the anti-deviation function, which can achieve zero power consumption operation. Furthermore, when disassembling the printer head 7, rotating the knob 20 causes the bidirectional lead screw 17 to rotate, causing the threaded slider 18 to drive the positioning block 19 to move out of the positioning slot 22. Then, pulling down the printer head 7 can remove it from the mounting base 6, thereby improving the convenience of disassembling the printer head 7.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
