Description

Technical Field

[0001] This invention relates to the field of printing equipment, specifically to a multi-axis support structure for a printer, its installation method, and the printer itself. Background Technology

[0002] In existing printers, there is typically a housing and internal components. The housing houses the internal components, providing protection and enhancing the appearance. The internal components usually include two spaced-apart parallel shafts and a printing component. The printing component is usually positioned between the two shafts and typically has a shaft that engages with shaft holes on the two shafts, allowing for installation and rotation or movement. However, for printers with more complex printing functions, the number of printing components is usually greater, resulting in a larger number of shafts. In existing technology, the shaft heights are generally consistent. During assembly, issues can arise such as one shaft being inserted into a shaft hole while another already assembled shaft (not properly assembled) jumps out of the hole, or multiple shafts failing to align simultaneously, leading to misalignment between some shafts and shaft holes and preventing simultaneous assembly. Both of these issues result in low assembly efficiency.

[0003] To solve this problem, existing technologies typically employ a multi-person installation method, with each person responsible for several shafts, ensuring that all shafts are aligned before inserting them into the shaft holes. This method has the following disadvantages: First, it consumes a huge amount of manpower; second, for printers that are not large in size, the operating space is already limited, making it difficult to operate when multiple people are assembling them. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a multi-axis support structure for a printer, its installation method, and a printer.

[0005] To achieve the above objectives, the present invention and its preferred embodiments employ the following technical solutions, but the embodiments are not limited to the following solutions:

[0006] Option 1: A multi-axis support structure for a printer, including...

[0007] A first shaft seat includes a seat body and a plurality of shafts. The seat body is provided with insertion holes corresponding to each of the shafts, and the first end of each shaft is inserted into the insertion hole.

[0008] The second bearing seat has a shaft hole corresponding to each of the shafts. The second end of the shaft is inserted into the shaft hole. The end face of the second end of each shaft and the shoulder of the corresponding shaft hole form a first distance along the axial direction of the shaft. For any first distance, the absolute value of the difference between the other first distances and the first distance forms a first difference set. In each first difference set, the number of first differences less than or equal to 1 mm does not exceed 3.

[0009] Option 2, based on Option 1, ensures that in each set of first differences, the number of first differences less than or equal to 1 mm does not exceed one.

[0010] Option 3, based on Option 1, the seat body is provided with a first limiting surface facing the second shaft seat and perpendicular to the axis direction, the second shaft seat is provided with a second limiting surface opposite to the first limiting surface; at least one of the shafts is provided with a third limiting surface and a fourth limiting surface respectively adapted to be opposite to the first limiting surface and the second limiting surface.

[0011] Option 4, based on Option 1, further includes retaining rings; at least one of the shafts has a retaining groove at its first end and / or second end; the ends of the shafts with the retaining grooves are respectively adapted to pass over the shaft hole and / or the insertion hole; the number of retaining rings corresponds to the retaining grooves; the retaining rings are adapted to extend into the retaining grooves and be limited by the groove wall along the axial direction; the size of the retaining rings is larger than the diameter of the shaft hole and / or the insertion hole, so as to be adapted to be opposite the side of the second shaft seat away from the seat body and the side of the seat body away from the second shaft seat, respectively.

[0012] Option 5, based on Options 1 to 4, the base body is provided with a first auxiliary mounting hole, and the second shaft seat is provided with a second auxiliary mounting hole that corresponds one-to-one with the first auxiliary mounting hole.

[0013] Option 6, a printer, characterized in that it includes a multi-axis support structure for a printer as described in any one of Options 1 to 5.

[0014] Option 7, an installation method for a multi-axis support structure for a printer, characterized in that: based on any one of Options 1 to 5, the installation method includes the following steps:

[0015] With the first end of each shaft supported by the seat, the shaft holes of the second shaft seat are aligned with the shafts of the first shaft seat along the axial direction, and the shafts are moved along the axial direction and close to the seat of the first shaft seat, so that each shaft is installed in the corresponding shaft hole in order of increasing first distance, until all shafts are installed.

[0016] Option 8, based on Option 7, involves locking the first and second shaft seats along the axial direction after all shafts are installed.

[0017] Option 9, based on Option 8 and Option 5, describes a multi-axis support structure for a printer, the installation method of which includes the following steps:

[0018] Before the second bearing seat is moved along the axial direction and close to the seat of the first bearing seat, the limiting pins on the auxiliary mounting fixture pass through the first auxiliary mounting hole and the second auxiliary mounting hole in sequence along the axial direction to make each shaft hole of the second bearing seat correspond to each shaft of the first bearing seat.

[0019] After the locking is completed, the limiting post on the auxiliary installation fixture is removed from the first auxiliary installation hole and the second auxiliary installation hole.

[0020] Option 10, based on Option 7, and based on the printer multi-axis support structure described in claim 2, further includes the following steps in the installation method before aligning the shaft holes of the second shaft holder with the shafts of the first shaft holder:

[0021] The corresponding holes on the base are inserted into one end of each shaft.

[0022] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0023] 1. In Scheme 1 and its preferred embodiments, a multi-axis support structure for a printer is provided. The shafts and the base within the printer are typically connected via a movable connection to achieve functionality. Therefore, the base has insertion holes corresponding to each shaft, and a second shaft seat has shaft holes. The first end of the shaft is inserted into the insertion hole, and the second end of the shaft is inserted into the shaft hole. The base and the second shaft seat are respectively used to support the two ends of each shaft, ensuring that the axes of each shaft are parallel to each other. During installation, while the base supports the first end of the shaft, the second shaft seat can be moved along the axial direction and closer to the base, allowing the shaft holes to be inserted into each shaft, thus completing the assembly of each shaft. When the two ends of the shaft are respectively inserted into the insertion hole and the shaft hole, the shoulder of each shaft hole opposite to the base and the end of the corresponding shaft away from the base form a first distance along the axial direction. For any first distance, the absolute value of the difference between other first distances and this first distance forms a first difference set; in each first difference set, there are 3 first differences less than or equal to 1 mm.

[0024] Generally, when the shaft extends more than 1mm into the shaft hole, it will not detach from the support of the second shaft seat and tilt under external pressure. Therefore, once the portion of the installed shaft extending into the shaft hole is greater than 1mm, subsequent shaft installations can proceed. The number of shafts of equal height is related to the number of assemblers. When assembling alone, generally only two shafts can be operated at the same time to align with the corresponding shaft holes on the second shaft seat. That is, one person assembles 1-2 shafts of equal height, and two people assemble 3-4 shafts together. Therefore, when one person assembles, the number of first differences less than or equal to 1mm in each first difference cluster does not exceed one, plus the shaft itself, and no more than two shafts can be assembled at the same time, which is suitable for single-person assembly. When two people assemble, the number of first differences less than or equal to 1mm in each first difference cluster does not exceed two or three, plus the shaft itself, and no more than four shafts can be assembled at the same time, which is suitable for two-person assembly. By setting different first distances, the sequential assembly of multiple shafts can be achieved, requiring only a small number of shafts to be assembled at the same time, thus facilitating assembly and requiring only a small number of people to complete the installation, reducing the waste of human resources.

[0025] 2. In Scheme 2 and its preferred embodiments, in each set of first differences, the number of first differences less than or equal to 1mm does not exceed 1, so single-person assembly can be achieved.

[0026] 3. In Scheme 3 and its preferred embodiments, when the third limiting surface is opposite to the first limiting surface and the fourth limiting surface is opposite to the second limiting surface, the shaft cannot wobble excessively along the axial direction during use.

[0027] 4. In Scheme 4 and its preferred embodiments, Scheme 3 has already achieved the prevention of the first and second shaft seats from getting close to each other. In this scheme, when the retaining ring extends into the retaining groove and is limited by the groove wall along the axial direction, the position of the retaining ring relative to the shaft along the axial direction cannot be changed. Furthermore, the size of the retaining ring is larger than the diameter of the shaft hole and the insertion hole, so the retaining ring cannot pass through the shaft hole and the insertion hole. This allows the side of the second shaft seat away from the seat body and the side of the seat body away from the second shaft seat to be opposite each other, preventing the shaft from shaking too much along the axial direction during use, or preventing the first and second shaft seats from separating from the shaft along the axial direction.

[0028] 5. In Scheme 5 and its preferred embodiments, by setting the first auxiliary mounting hole and the second auxiliary mounting hole, before installing the shaft assembly, the limiting post on the auxiliary mounting fixture can be pre-inserted through the first auxiliary mounting hole and the second auxiliary mounting hole, thereby ensuring that the seat body and the second shaft seat are flush, and enabling each shaft hole on the second shaft seat to correspond one-to-one with each shaft, realizing the function of auxiliary positioning and facilitating assembly.

[0029] 6. In Scheme 6 and its preferred embodiments, the printer includes a multi-axis support structure as described above, and has the beneficial effects brought about by the multi-axis support structure.

[0030] 7. In Scheme 7 and its preferred embodiments, the shafts are installed sequentially, which facilitates assembly and saves manpower.

[0031] 8. In Scheme 8 and its preferred embodiments, the first shaft seat and the second shaft seat are fixed along the axial direction by locking to prevent the shaft from shaking too much along the axial direction, or to prevent the first shaft seat and the second shaft seat from separating from the shaft along the axial direction.

[0032] 9. In Scheme 9 and its preferred embodiments, the positioning of the shaft hole and the shaft is achieved by setting the first auxiliary mounting hole and the second auxiliary mounting hole in cooperation with the limiting post, which facilitates assembly. After assembly, the limiting post can be removed, and the auxiliary fixture can be reused multiple times.

[0033] 10. In Scheme 10 and its preferred embodiments, the insertion hole is first installed at one end of each shaft to pre-support one end, so that the shaft hole of the second shaft seat can be inserted into the shaft. Attached Figure Description

[0055] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0056] A multi-axis support structure for a printer includes a first axis support, a second axis support 20, and a retaining ring 40.

[0057] The first shaft holder includes a base 10 and several shafts protruding from the base 10. The base 10 is used to support the first ends of each shaft. In printer shafts, they are generally used in the following places: the print head, which is rotatably connected to the base 10. Of course, the print head can also be separated from the shaft, with the shaft fixed to the base 10 and the print head rotating around the shaft; the paper feed roller and paper trailing roller are rotatably connected to the base 10; the printing roller is also rotatably connected to the base 10; and the paper return shaft is slidably connected to the base 10.

[0058] Therefore, in most cases, the shaft and the base 10 are designed to be assembleable and movably connected, firstly to achieve functionality, and secondly to facilitate processing. Specifically, the base 10 is provided with multiple insertion holes 101 that penetrate the base 10 along the axial direction of the shaft. Each insertion hole 101 corresponds to the shaft, and one end of the shaft is inserted into the insertion hole 101, which is supported by the hole wall. The base 10 is also provided with a first limiting surface 102 facing the second shaft seat 20 and perpendicular to the axial direction, and a first auxiliary mounting hole 103 that penetrates the base 10 along the axial direction. In this embodiment, there are four first auxiliary mounting holes 103, which are circular holes, and the four first auxiliary mounting holes 103 are arranged around the base 10.

[0059] The second bearing seat 20 is provided with bearing holes 201 corresponding to each bearing. When the second bearing seat 20 is parallel to the seat body 10, the bearing hole 201 corresponding to the same bearing also corresponds to the insertion hole 101 corresponding to that bearing. The second bearing seat 20 is adapted to be close to the first bearing seat along the axial direction so that the bearing hole 201 is inserted into the other end of each bearing and supports each bearing. At this time, the two ends of the bearing are supported by the hole wall of the bearing hole 201 and the hole wall of the insertion hole 101, respectively. The insertion hole 101 and the bearing hole 201 can be designed as round holes (for rotation) or strip holes (for sliding) according to the function to be performed by the bearing. The second bearing seat 20 is provided with a second limiting surface 202 opposite to the first limiting surface 102, and the second limiting surface 202 is also perpendicular to the axial direction. The second bearing seat 20 is provided with two second auxiliary mounting holes 203 corresponding one-to-one with the first auxiliary mounting holes 103, and the number of the two auxiliary mounting holes 203 is also four.

[0060] At least one shaft is provided with a third limiting surface 301 and a fourth limiting surface 302, which are respectively adapted to abut against the first limiting surface 102 and the second limiting surface 202. In this embodiment, the diameter of the middle part of the printing roller is larger than the diameter of the two ends of the printing roller. The surfaces connecting the middle part of the printing roller to the two ends respectively form the third limiting surface 301 and the fourth limiting surface 302. The two ends of the printing roller are respectively adapted to be inserted into the shaft hole 201 and the insertion hole 101, and the third limiting surface 301 and the fourth limiting surface 302 are opposite to the first limiting surface 102 and the second limiting surface 202, so as to limit the excessive shaking along the axial direction of the shaft during use. For the shaft that needs to rotate, the third limiting surface 301 and the fourth limiting surface 302 are not in close contact with the first limiting surface 102 and the second limiting surface 202. There can be a certain distance between the third limiting surface 301 and the first limiting surface 102, and between the fourth limiting surface 302 and the second limiting surface 202, to prevent excessive friction during rotation.

[0061] At least one shaft has a first end and a second end with a groove 303. The two ends of the shaft with the groove 303 are respectively adapted to pass through the shaft hole 201 and the insertion hole 101. The number of retaining rings 40 corresponds to the groove 303. The retaining rings 40 are adapted to extend into the groove 303 and are limited by the groove wall of the groove 303 along the axial direction so that the two are relatively fixed along the axial direction. The size of the two retaining rings 40 is larger than the diameter of the shaft hole 201 and the insertion hole 101, so that the retaining rings 40 cannot pass through the shaft hole 201 and the insertion hole 101. The two retaining rings 40 are respectively opposite the side of the second shaft seat 20 away from the seat body 10 and the side of the seat body 10 away from the second shaft seat 20, thereby preventing excessive shaking of the shaft along the axial direction during use. The first end and the second end of the shaft are the two ends along the axial direction.

[0062] When only one of the first and second ends of the shaft has a groove 303, the other end has a limiting part protruding in a direction away from its circumference. Taking the first end having a limiting part and the second end having a groove 303 as an example, the size of the limiting part is larger than the insertion hole 101.

[0063] In this embodiment, the paper feed roller, paper drag roller, print head, and paper return and recovery shaft are all equipped with slots 303. Some shafts have slots 303 at both ends, while some shafts have slots 303 at only one end and a limiting part at the other end.

[0064] This embodiment illustrates a method for installing a multi-axis support structure for a printer, including the following steps:

[0065] S1: Insert each of the insertion holes 101 on the seat body 10 into one end of each shaft, and make the slots 303 of some shafts pass over the insertion holes 101, so that the retaining ring 40 is installed in the slots 303 and faces the side of the seat body 10 away from the second shaft seat 20.

[0066] S2: Pass the limiting pins on the auxiliary mounting fixture through the first auxiliary mounting hole 103 on the seat 10 and the second auxiliary mounting hole 203 on the second bearing 20 in sequence along the axial direction, so that the seat 10 and the second bearing 20 are approximately parallel.

[0067] S3: Move the second shaft seat 20 along the axial direction and get closer to the seat body 10 of the first shaft seat, so that each shaft is installed in the corresponding shaft hole 201 in order of increasing first distance, until each shaft is installed.

[0068] S4: Locking, to fix the first bearing seat and the second bearing seat 20 along the axial direction; specifically, a support column is provided between the bearing body 10 and the second bearing seat 20, and the bearing body 10 and the second bearing seat 20 are locked together by screws passing through the bearing body 10 and the second bearing seat 20, thereby fixing the bearing body 10 and the second bearing seat 20 along the axial direction.

[0069] In this step, after the shaft is installed, its slot 303 passes over the shaft hole 201, and is installed in the slot 303 by the retaining ring 40 and abuts against the side of the second shaft seat 20 away from the seat body 10. During use, the shaft will not wobble too much along the axial direction, or prevent the first shaft seat and the second shaft seat 20 from separating from the shaft along the axial direction.

[0070] S5: Remove the limiting post on the auxiliary mounting fixture from the first auxiliary mounting hole 103 and the second auxiliary mounting hole 203.

[0071] Installation is assisted by limiting posts. When the limiting posts pass through the first auxiliary mounting hole 103 and the second auxiliary mounting hole 203, the shaft holes 201 of the second shaft seat 20 correspond to the shafts of the first shaft seat, and provide a guide for the movement of the second shaft seat 20, facilitating assembly. When the first auxiliary mounting hole 103 or the second auxiliary mounting hole 203 is a round hole, multiple holes need to be provided to prevent the seat 10 or the second shaft seat 20 from rotating around the limiting posts, which would affect positioning. In this embodiment, four holes are provided, located at the four corners. Furthermore, after assembly, the limiting posts can be removed, allowing for multiple uses of the auxiliary fixture.

[0072] In step S1, the step of moving part of the shaft through the slot 303 past the insertion hole 101 and installing it in the slot 303 with the retaining ring 40 facing the side of the seat 10 away from the second shaft seat 20 can also be performed in step S4.

[0073] The following describes the simple assembly principle of S3. When assembly is complete, both ends of the shaft are supported by the seat 10 and the second shaft seat 20, respectively. The shoulder of each shaft hole 201 opposite to the seat 10 and the end of the corresponding shaft away from the seat 10 form a first distance along the axial direction, as shown below. Figures 8-10 For any given first distance, the absolute values ​​of the differences between other first distances and that first distance form a first difference set; within each first difference set, the number of first differences less than or equal to 1 mm does not exceed 3. The peripheral area of ​​the shaft hole 201 on the side of the second shaft seat 20 facing the seat body 10 is the shoulder of the shaft hole 201 opposite to the seat body 10. The number of shafts of equal height is related to the number of assemblers. When one person assembles alone, generally only two shafts can be aligned at the same time, that is, 1-2 shafts of equal height when one person assembles alone, and 3-4 shafts when two people assemble together. Therefore, when one person installs, the number of first differences less than or equal to 1 mm in each first difference set does not exceed 1, plus the shaft itself, and the number of shafts assembled at the same time does not exceed 2, which is suitable for single-person assembly; when two people install, the number of first differences less than or equal to 1 mm in each first difference set does not exceed 2 or 3, plus the shaft itself, and the number of shafts assembled at the same time does not exceed 4, which is suitable for two-person assembly.

[0074] Generally, when the shaft extends more than 1mm into the shaft hole 201, the shaft will not be misaligned and will not jump out when assembled. Therefore, the shaft must extend more than 1mm before proceeding with the subsequent shaft installation. The first difference remains unchanged before and after the shaft is installed on the second shaft seat 20. Therefore, for ease of describing the assembly process, as follows... Figure 11When the seat 10 has supported one end of each shaft and the second shaft seat 20 is in a position away from each shaft along the axial direction, the shoulder of each shaft hole 201 opposite to the seat 10 and the end of the corresponding shaft away from the seat 10 form a second distance along the axial direction. For any second distance, the absolute value of the difference between the other second distances and the second distance forms a first difference set. The first difference set formed by the second distance is consistent with the first difference set formed by the first distance. The following example is that the shaft is assembled in place with an insertion of 1.1mm into the shaft hole 201, the number of shafts is 5, and the number of first differences less than or equal to 1mm in each first difference set does not exceed 1.

[0075] Example 1:

[0076]

[0077] As shown in the table above, during the process of shaft 1 moving 2.1mm and then extending 1.1mm into shaft hole 201, only shaft 2 begins to be installed. Therefore, during the installation process, it is only necessary to ensure the assembly of shafts 1 and 2. Shaft 3 has not yet begun to be installed during the process of shaft 2 moving 2.3mm, so it is not necessary to switch from operating shafts 1 and 2 to operating shafts 2 and 3. However, during the installation of shafts 3 and 4, shaft 5 begins to be installed just as shaft 4 moves 4.1mm. Therefore, it is necessary to switch from operating shafts 3 and 4 to operating shafts 4 and 5. Thus, during the above installation, it is sufficient to ensure that two shafts are assembled at the same time, which is suitable for one person to install.

[0078] Example 2:

[0079]

[0080] As shown in the table above, the installation of shafts 1 and 2 is the same as in Example 1. However, when shaft 3 moves 3.5mm, shafts 4 and 5 also need to be installed at the same time. For single-person assembly, it is not easy for a single person to assemble three shafts at the same time, so there is a problem of difficult assembly. However, Example 2 is easy to assemble for two-person assembly.

[0081] In summary, this embodiment demonstrates that by varying the second distance, different first distances can facilitate sequential assembly of multiple axes, ensuring only a small number of axes are assembled at any given time. This simplifies assembly, reduces the number of personnel required for installation, and minimizes the waste of human resources. The different first distances can be designed to be caused by one or more of the following reasons: varying axis lengths, such as... Figure 9 The length of the shaft protruding from the seat 10 varies, such as Figure 8 , Figure 9 The shoulder of each shaft hole 201 opposite to the seat body 10 is not on the same plane, such as Figure 10It should be understood that a larger initial distance interval makes assembly easier, but at the same time, a larger initial distance interval may lead to a larger size of the printer's multi-axis support structure, indirectly leading to an increase in the printer's size.

[0082] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
