Description

Technical Field

[0001] The utility model relates to the technical field of high-speed printers, in particular to a dual-motor material receiving drive mechanism of a high-speed printer. Background Art

[0002] With the improvement of printer performance and the continuous development of various electronic control methods, printing accuracy and efficiency have been greatly improved compared to traditional solutions, and what follows is the upgrade of supporting equipment in the printer.

[0003] Among them, the main functional component in the printer's receiving system is the receiving roller. The receiving roller is often driven by an independent motor through a belt to rotate and receive materials in a certain rhythm. Since a buffer mechanism is provided in the roller system, the operation of the receiving roller is usually required to be stable and slow.

[0004] With the development of high-speed printers, the traditional stable and slow-speed operation solutions need to be upgraded to meet the high-speed material collection requirements under high-speed printing requirements.

[0005] The high-speed material collection action usually has the following problems: the material collection roller itself is heavy, and after the material collection reaches a certain level, the load increases significantly. However, the printer often operates in a step-by-step or intermittent walking mode, and high-speed starting and stopping becomes a must. Under this constraint, the high efficiency and high precision of the material collection drive mechanism are challenged.

[0006] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0007] The utility model aims to solve the deficiencies of the prior art and thus provide a high-speed printer dual-motor material receiving drive mechanism with abundant power, high travel efficiency and high travel precision.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a high-speed printer dual-motor material receiving drive mechanism, including a frame, a material receiving roller, a first drive motor, a second drive motor and a start-stop positioning component;

[0009] The two ends of the receiving roller span across the frame, and the first drive motor and the second drive motor directly drive the two ends of the receiving roller respectively;

[0010] The start-stop positioning assembly is installed at one end of the receiving roller and is used to determine the start-stop angle of the receiving roller; the first drive motor and the second drive motor work synchronously under the control of the controller.

[0011] Based on the above, the start-stop positioning assembly includes a rotating arm fixed to one end of the receiving roller, and a sensor probe fixedly installed relative to the rotating arm. During the rotation of the rotating arm, the sensor probe passes through the sensing trigger area to determine the start-stop angle of the receiving roller.

[0012] Based on the above, the first drive motor and the second drive motor each include a high-speed motor and a reducer module, and the reducer module is installed on the outside of the frame through a bracket.

[0013] Based on the above, the receiving roller includes a roller body and a coupling, the coupling includes a receiving roller chuck and a shaft body, the shaft body is driven by the output end of the reducer module, and the receiving roller chuck is used to fix the end of the roller body.

[0014] Based on the above, the receiving roller chuck includes an annular chuck and a clamp installed at the center of the annular chuck, the clamp includes a first clamp with an open top and a V-shaped groove and a second clamp for covering the open top of the first clamp, the first clamp and the second clamp are both fixed on the annular chuck, the enclosed area of ​​the first clamp and the second clamp constitutes a special-shaped hole, and the end of the roller body is shaped to fit the special-shaped hole.

[0015] Based on the above, the special-shaped hole is a square hole, a diamond hole or an elliptical hole, and the end of the roller body is in the same shape.

[0016] Based on the above, the annular chuck is radially provided with a penetrating assembly hole, the end of the shaft body is provided with a through hole corresponding to the assembly hole, and the center of the annular chuck is provided with a special-shaped hole for constraining the end of the shaft body, and the end of the shaft body is a matching special-shaped shape.

[0017] Based on the above, a bearing seat and a bearing are further provided for the shaft body, a sleeve structure is provided on the outside of the bearing seat, the opening of the sleeve structure is an oblique opening, and a snap-on for pulling the shaft body is provided in the area of ​​the shaft body exposed corresponding to the oblique opening.

[0018] Based on the above, the upper end of the first fixture and the lower end of the second fixture are provided with matching inclined surfaces for assembling and positioning the first fixture and the second fixture.

[0019] Compared with the prior art, the utility model has substantial characteristics and progress. Specifically, the utility model changes the material collection roller into a dual-motor direct drive. In the case of large width and high-speed printing, the dual motors provide sufficient power to ensure the stability of the material collection process. At the same time, the high precision of the dual-motor direct drive prevents the start-stop delay problem caused by belt transmission and inertial force interference in the traditional solution, making the rolled printing medium more compact and efficient, and more efficient.

[0020] Furthermore, both motors drive both ends of the roller body of the receiving roller through a coupling. The coupling uses a receiving roller chuck as a carrier. The first clamp and the second clamp cooperate to connect the roller body and the shaft body of the coupling together, thereby achieving stable transmission of the receiving roller and facilitating the unloading process of the material after winding.

[0021] Furthermore, the design of the receiving roller chuck and the design of the bearing seat in the coupling make it easier to disassemble, assemble and maintain the shaft body and roller body of the receiving roller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0032] like Figure 1-Figure 8As shown, a dual-motor material receiving drive mechanism of a high-speed printer includes a frame 1, a material receiving roller 2, a first drive motor 3, a second drive motor 4 and a start-stop positioning component 5.

[0033] The two ends of the receiving roller 2 span across the frame 1, and the first drive motor 3 and the second drive motor 4 directly drive the two ends of the receiving roller 2 respectively;

[0034] The start-stop positioning assembly 5 is installed at one end of the receiving roller 2 to determine the start-stop angle of the receiving roller 2; the first drive motor 3 and the second drive motor 4 work synchronously under the control of the controller.

[0035] Specifically, in the present embodiment, the start-stop positioning assembly 5 comprises a rotating arm 51 fixed to one end of the receiving roller, and a sensor probe 52 fixedly mounted relative to the rotating arm. During the rotation of the rotating arm 51, the sensor probe 52 passes through the sensing triggering area to determine the start-stop angle of the receiving roller 2. The principle is similar to that of a proximity switch, which is used to trigger the start-stop position of the motor to ensure that the motors at both ends have the same reference reference. In other embodiments, the start-stop positioning assembly can also use a counter-beam infrared sensor or other forms of proximity switches.

[0036] In this embodiment, the first drive motor 3 and the second drive motor 4 both include a high-speed motor 31 and a reducer module 32. The reducer module 32 is installed on the outside of the frame 1 through a bracket, and the sensor probe 52 of the start-stop positioning assembly 5 is installed on the external shell of the reducer module 32.

[0037] In this embodiment, the receiving roller 2 includes a roller body 21 and a coupling 22. The coupling 22 includes a receiving roller chuck 23 and a shaft body 24. The shaft body 24 is driven by the output end of the reducer module 32. The receiving roller chuck 23 is used to fix the end of the roller body 21.

[0038] Specifically, the receiving roller chuck 23 includes an annular chuck 231 and a fixture installed at the center of the annular chuck 231, the fixture includes a first fixture 232 with an open top and a V-shaped groove and a second fixture 233 used to cover the open top of the first fixture 232, the first fixture 232 and the second fixture 233 are both fixed on the annular chuck 231, the enclosed area of ​​the first fixture 232 and the second fixture 233 constitutes a special-shaped hole, and the end of the roller body 21 is shaped to fit the special-shaped hole. The upper end of the first fixture 232 and the lower end of the second fixture 233 are provided with matching inclined surfaces for assembly and positioning of the first fixture 232 and the second fixture 233.

[0039] In this embodiment, the special-shaped hole is a square hole, a diamond hole or an elliptical hole, and the ends of the roller body and the shaft body are in the same shape.

[0040] The annular chuck 231 is radially provided with a penetrating assembly hole 234, and the end of the shaft body 24 is provided with a through hole 235 corresponding to the assembly hole. The center of the annular chuck 231 is provided with a special-shaped hole for constraining the end of the shaft body, and the end of the shaft body 24 is a matching special-shaped shape. In this embodiment, the shape of the special-shaped hole is rectangular, and the shape of the end of the shaft body 24 is also rectangular.

[0041] The shaft body 24 is also provided with a bearing seat 241 and a bearing 242. A sleeve structure 243 is provided on the outside of the bearing seat 242. The opening of the sleeve structure 243 is an oblique opening. A snap-on 244 for pulling out the shaft body is provided in the exposed area of ​​the oblique opening of the shaft body 24, which is used to fix the shaft body when disassembling and assembling the shaft body 24.

[0042] Working principle:

[0043] Due to the printing requirements of high-speed printers, the span is large, the speed is high, and the printing medium is reeled in quickly. However, printers usually use step-by-step printing, so there is a need for intermittent operation of reeling and walking. As the thickness of the reeled printing medium increases, the load increases significantly, which brings obstacles to the rapid response of the reeling action.

[0044] When dual-motor drive is used, these fast-response tasks can be accomplished due to the more abundant power.

[0045] In addition, after the winding is completed, the winding roller needs to be removed together with the wound material. Due to the limitation of the direct-connected motor drive mode, a coupling needs to be configured to improve the disassembly and assembly efficiency.

[0046] A clamp structure in which a first clamp and a second clamp cooperate is arranged on the outer side of the coupling to constrain and connect the roller body of the receiving roller, and the roller body is disassembled and assembled by disassembling the clamp.

[0047] The inner side of the coupling is directly provided with a special-shaped hole and an assembly hole structure to connect and fix the shaft body.

[0048] In this structural form, the receiving roller has both high transmission efficiency and the ability to be flexibly disassembled and assembled.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
