Description

Technical Field

[0001] This utility model belongs to the field of digital printing technology, and in particular relates to a printing platform lifting and adjusting mechanism. Background Technology

[0002] Existing digital printing equipment uses a stepped adjustment structure for printing platform height adjustment. This means that the printing platform works in conjunction with a rotating step. By rotating the rotating structure containing the rotating step, the printing platform is moved to work with the corresponding step, thereby achieving height adjustment of the printing platform. However, this structure limits the height adjustment range of the printing platform to the height of the adjacent step, making the adjustment range of the printing platform fixed and unable to adapt to a wider range of production needs. Utility Model Content

[0003] The printing platform lifting and adjusting mechanism provided by this utility model aims to solve the problem that the limited height adjustment of the printing platform in the prior art makes it unable to adapt to a wider range of production needs.

[0004] This utility model is implemented as follows: a printing platform lifting and adjusting mechanism, comprising:

[0005] The base is equipped with a first slider that can move horizontally;

[0006] A movable seat is spaced above the base, and the movable seat is provided with a second slider that can move along the horizontal direction. The movable seat is used to mount the printing platform.

[0007] The first connecting rod is inclinedly disposed between the base and the movable seat, with one end movably connected to the first slider and the other end movably connected to the movable seat;

[0008] The second link is arranged to cross the first link and is movably connected to the first link in the middle. One end of the second link is movably connected to the base and the other end is movably connected to the second slider. When the first slider moves in the horizontal direction, the movable seat moves in the vertical direction.

[0009] An adjusting element is provided on the base or the movable seat and drives the first slider or the second slider to move horizontally.

[0010] Furthermore, the adjusting component is an adjusting screw, which is threadedly engaged with either the first slider or the second slider.

[0011] Furthermore, the printing platform lifting and adjusting mechanism also includes a locking component, which is disposed on the base or the movable seat and used to lock the adjusting screw after it is rotated.

[0012] Furthermore, the locking component includes:

[0013] A locking seat is fixed to the base or the movable seat. The locking seat has a first through hole through which the adjusting screw passes. The adjusting screw passes through the first through hole and is threadedly engaged with the first slider or the second slider. The first through hole has a slit along its axial direction, and extensions are provided on both sides of the slit.

[0014] A locking element is provided on the locking seat and passes through the crack to adjust the spacing of the crack.

[0015] Furthermore, the locking seat is provided with second through holes on opposite sides of the crack, and the locking member includes a rod that passes through the second through hole and is threadedly connected to the second through hole, and a head that is connected to the rod and can abut against one side of the crack. The head can be screwed into or out of the second through hole, and the head can squeeze the side wall of the crack it abuts against.

[0016] Furthermore, the locking seat is made of metal material, and the locking seat has a partition groove on one side of the crack. The partition groove extends from the surface of the locking seat toward the crack, and the projection of the partition groove toward the first through hole falls within the range of the first through hole.

[0017] Furthermore, the adjusting screw is provided with a first limiting part and a second limiting part at intervals along its axial direction, and the first slider or the second slider is placed between the first limiting part and the second limiting part.

[0018] Furthermore, there are two of each of the first and second connecting rods. One first connecting rod and one second connecting rod are movably connected to form a group. The two groups of first and second connecting rods are arranged in parallel. One end of each of the two first connecting rods is movably connected to the opposite sides of the first slider, and one end of each of the two second connecting rods is movably connected to the opposite sides of the second slider.

[0019] Furthermore, the printing platform lifting and adjusting mechanism also includes a third link, which is rotatably connected to two sets of the first link and the second link.

[0020] Furthermore, the base is horizontally provided with a first slide rail, the first slider cooperates with the first slide rail and can move along the first slide rail, and the movable seat is horizontally provided with a second slide rail, the second slider cooperates with the second slide rail and can move along the second slide rail.

[0021] The beneficial effects achieved by this utility model are as follows: by setting the first and second connecting rods to cross and connect the base and the movable seat, and movably connecting the first connecting rod to the first slider of the base and the second connecting rod to the second slider, the adjusting component can change the angle between the first and second connecting rods toward the movable seat when driving the first or second slider to move horizontally. This allows the movable seat to be raised and lowered by the first and second connecting rods to adjust its height. Furthermore, the movement of the first or second slider to raise and lower the movable seat allows for stepless adjustment of the printing platform, resulting in higher adjustment precision and better meeting the height requirements of different printing platforms.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] See Figures 1-2This utility model provides a printing platform lifting and adjusting mechanism, including a base 1, a movable seat 2, a first connecting rod 3, a second connecting rod 4, and an adjusting member 5. The base 1 has a first slider 11 that can move horizontally. The movable seat 2 is spaced above the base 1 and used to mount the printing platform 100. The movable seat 2 has a second slider 21 that can move horizontally. The first connecting rod 3 is inclined between the base 1 and the movable seat 2, with one end movably connected to the first slider 11 and the other end movably connected to the movable seat 2. The second connecting rod 4 is intersected with the first connecting rod 3 and movably connected to the first connecting rod 3 in the middle. One end of the second connecting rod 4 is movably connected to the base 1, and the other end is movably connected to the second slider 21. When the first slider 11 moves horizontally, the movable seat 2 moves vertically. The adjusting member 5 is located on the base 1 or the movable seat 2 and drives the first slider 11 or the second slider 21 to move horizontally.

[0031] It should be noted that the movable connections between the first link 3 and the second link 4, between the first link 3 and the first slider 11 and the movable seat 2, and between the second link 4 and the second slider 21 and the base 1 can all be hinged connections.

[0032] By setting the first connecting rod 3 and the second connecting rod 4 to cross each other to connect the base 1 and the movable seat 2, and making the first connecting rod 3 movably connected to the first slider 11 of the base 1, and the second connecting rod 4 movably connected to the second slider 21, the adjusting member 5 can change the angle between the first connecting rod 3 and the second connecting rod 4 toward the movable seat 2 when driving the first slider 11 or the second slider 21 to move horizontally. Thus, the movable seat 2 can be raised and lowered by the first connecting rod 3 and the second connecting rod 4 to adjust the height of the movable seat 2. The movement of the first slider 11 or the second slider 21 to raise and lower the movable seat 2 can perform stepless adjustment of the printing platform 100, with higher adjustment accuracy, and can better meet the height requirements of different printing platforms 100.

[0033] The printing platform lifting and adjusting mechanism provided by this utility model can infinitely adjust the printing platform 100 with higher adjustment accuracy, and can meet the height requirements of different printing platforms 100.

[0034] In this embodiment, the adjusting member 5 can be set on the movable seat 2, so that the adjusting member 5 can be raised, making it easier for personnel to operate the adjusting member 5.

[0035] Specifically, the adjusting component 5 is an adjusting screw, which is threaded into the first slider 11 or the second slider 21. Thus, by rotating the adjusting screw, the first slider 11 or the second slider 21 can be moved horizontally, making the adjustment simple and precise.

[0036] See Figure 3Specifically, the base 1 or the movable seat 2 is provided with a third through hole 8 for the adjusting member 5 to pass through. The adjusting member 5 passes through the third through hole 8 and is threadedly engaged with the first slider 11 or the second slider 21. The adjusting member 5 is engaged with the third through hole 8 and can rotate within the third through hole 8. The third through hole 8 provides support for the adjusting member 5.

[0037] See Figure 1 Furthermore, the printing platform lifting and adjusting mechanism also includes a locking component 6, which is located on the base 1 or the movable seat 2 and is used to lock the adjusting screw after it is rotated. This allows the printing platform to remain in its current position after being adjusted to the required height.

[0038] See Figures 2-4 Specifically, the locking assembly 6 includes a locking seat 61 and a locking member 62. The locking seat 61 is fixed to the base 1 or the movable seat 2. The locking seat 61 has a first through hole 611 through which an adjusting screw passes. The adjusting screw passes through the first through hole 611 and is threadedly engaged with the first slider 11 or the second slider 21. The first through hole 611 has a slit 612 along its axial direction. The locking member 62 is disposed on the locking seat 61 and passes through the slit 612 to adjust the spacing of the slits 612. Thus, after the target height of the printing platform is adjusted by the adjusting member 5, the spacing of the slits 612 is adjusted by the locking member 62, which can cause the wall of the first through hole 611 to grip the adjusting screw, thereby locking the adjusting screw and preventing the adjusting screw from rotating and thus causing the printing platform to rise or fall.

[0039] See Figures 3-4 Furthermore, the locking seat 61 can be made of metal, such as, but not limited to, aluminum, to ensure the strength of the adjusting screw. The locking seat 61 has a partition groove 614 on one side of the crack 612. The partition groove 614 extends from the surface of the locking seat 61 towards the crack 612, and the projection of the partition groove 614 toward the first through hole 611 falls within the range of the first through hole 611 of the locking seat. By providing the partition groove 614, the connection strength between the portion on one side of the crack 612 and the main body of the locking seat 61 can be weakened, thereby facilitating the adjustment of the crack 612 spacing by the locking member 62.

[0040] Specifically, the projection of the partition groove 614 toward the first through hole 611 can be located on the diameter of the first through hole 611, that is, the position of the partition groove 614 on the locking seat 61 corresponds to the diameter of the first through hole 611. This ensures that the part of the locking seat located between the crack 612 and the partition groove 614 has good elastic deformation while also ensuring sufficient force to drive the hole wall of the first through hole 611 to clamp the rod body 621.

[0041] See Figure 5Furthermore, the locking seat 61 has second through holes 613 on opposite sides of the crack 612. The locking member 62 includes a rod 621 that passes through and is threadedly connected to the second through hole 613, and a head 622 connected to the rod 621 and abutting against one side of the crack 612. The rod 621 is screwed into or out of the second through hole 613, and the head 622 can press against the side wall of the crack 612 it abuts against. Thus, by rotating the head 622, the rod 621 can be moved on the second through hole 613, thereby adjusting the spacing of the cracks 612.

[0042] See Figure 3 Furthermore, the adjusting screw is provided with a first limiting part 51 and a second limiting part 52 spaced apart along its axial direction, and the first slider 11 or the second slider 21 is placed between the first limiting part 51 and the second limiting part 52. The first limiting part 51 and the second limiting part 52 can limit the movement of the first slider 11 or the second slider 21, and the distance between the first limiting part 51 and the second limiting part 52 forms the travel distance of the first slider 11 or the second slider 21.

[0043] See Figure 2 Specifically, in this embodiment, there are two first connecting rods 3 and two second connecting rods 4. One first connecting rod 3 and one second connecting rod 4 are movably connected to form a set. The two sets of first connecting rods 3 and second connecting rods 4 are arranged in parallel. One end of each first connecting rod 3 is movably connected to opposite sides of the first slider 11, and one end of each second connecting rod 4 is movably connected to opposite sides of the second slider 21. In this way, the two sets of first connecting rods 3 and second connecting rods 4 form a planar structure in the horizontal direction, which can better support the printing platform and adjust the height of the printing platform, thereby improving the stability of the printing platform.

[0044] See Figure 2 Furthermore, the printing platform lifting and adjusting mechanism also includes a third link 7, which is rotatably connected to two sets of first links 3 and second links 4. Specifically, the two ends of the third link 7 are respectively threaded through the first links 3 and the second links 4 and rotatably connected to them. The third link 7 can improve the structural stability between the two sets of first links 3 and second links 4, thereby further improving the stability of the printing platform.

[0045] See Figure 3 Specifically, the base 1 is horizontally provided with a first slide rail 12, and the first slider 11 cooperates with the first slide rail 12 and can move along the first slide rail 12. The movable seat 2 is horizontally provided with a second slide rail 22, and the second slider 21 cooperates with the second slide rail 22 and can move along the second slide rail 22. This facilitates the horizontal movement of the first slider 11 on the base 1 and the horizontal movement of the second slider 21 on the movable seat 2. At the same time, the first slide rail 12 can provide guidance for the movement of the first slider 11, and the second slide rail 22 can provide guidance for the movement of the second slider 21.

[0046] In this embodiment, two slide rails 12 and two slide rails 22 can be provided, which can make the first slider 11 and the second slider 21 move smoothly.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
