Description

Technical Field

[0001] This utility model relates to the field of pad printing machine worktable height adjustment technology, and in particular to a pad printing machine worktable height fine adjustment component. Background Technology

[0002] Pad printing machines are industrial devices specifically designed for high-precision printing on complex or irregular surfaces. They use a flexible silicone head to transfer ink from the printing plate to the workpiece surface and are widely used for printing small areas, multi-color, and high-precision patterns.

[0003] With the development of the manufacturing industry, product forms have shifted from simple flat surfaces to complex 3D curved surfaces. Traditional fixed-height printing methods cannot adapt to the surface undulations of different workpieces, and the workpieces have different sizes. It is necessary to control the contact pressure between the printing head and the workpiece through height adjustment, requiring the equipment to have dynamic adjustment capabilities. Therefore, a height micro-adjustment component for pad printing machine worktable is needed, which can adapt to height.

[0004] Currently, the height adjustment device of pad printing machines on the market consists of a screw and nut structure. The worktable is raised and lowered by manually rotating the screw. Because the height adjustment of this device is affected by the operator's experience, the accuracy of adjustment is low for each product. To solve the above problem, the existing technology adds a scale to the device. The product is adjusted to a specific position by observing the scale to ensure the accuracy of the adjustment. However, in actual use, the operator needs to repeatedly rotate the screw for fine adjustment. The single adjustment stroke is small and cannot quickly match the height requirements of different products, which reduces production efficiency and cannot meet the needs of users. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a table height fine-tuning component for pad printing machines, which aims to improve the problem that the single adjustment stroke is small when fine-tuning is performed by rotating a screw in the prior art, making it impossible to quickly match the height requirements of different products.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pad printing machine worktable height fine-adjustment component, including a sandwich plate, a base plate fixedly connected to the bottom of the sandwich plate, a support shell fixedly connected to the top of the base plate, a rack slidably connected to the left side inside the support shell, the top of the rack penetrating the support shell, a transmission rod rotatably connected to the upper middle part of the front side of the support shell, a gear fixedly connected to the rear end of the transmission rod penetrating the support shell, the left side of the gear meshing with the rack, a housing fixedly connected to the top of the rack, a rotating rod rotatably connected to the bottom outer side of the housing, a worm gear fixedly connected to the rear end of the rotating rod penetrating the housing, a lead screw rotatably connected inside the housing, a worm wheel fixedly connected to the bottom outer side of the lead screw, the worm wheel meshing with the worm gear, a support column threadedly connected to the top outer side of the lead screw, a work frame fixedly connected to the top of the support column penetrating the housing, and a positioning mechanism provided inside the sandwich plate, the positioning mechanism being used to position the height of the worktable, facilitating quick reset after the worktable height changes.

[0007] As a further description of the above technical solution:

[0008] The positioning mechanism includes a bidirectional threaded rod, which is disposed on the upper inner side of the sandwich panel. A sliding groove is provided on the rear inner side of the sandwich panel, and a slider is slidably connected inside the sliding groove. A positioning rod is fixedly connected to the bottom of the sliding groove, and the top of the positioning rod passes through the slider. Positioning clamps are threadedly connected to both the left and right sides of the outer wall of the bidirectional threaded rod, and a rotating wheel is fixedly connected to the right side of the outer wall of the bidirectional threaded rod.

[0009] As a further description of the above technical solution:

[0010] A pull rod is slidably connected to the upper right side of the support shell. The pull rod passes through the support shell and is fixedly connected to an internal gear ring. The internal gear ring meshes with a gear. A spring is provided on the outer side of the left end of the pull rod. The left end of the spring is fixedly connected to the internal gear ring, and the other end of the spring is fixedly connected to the support shell.

[0011] As a further description of the above technical solution:

[0012] The front left and right sides of the sandwich panel are fixedly connected to slide rails, and the left and right ends of the work frame are slidably connected inside the corresponding slide rails.

[0013] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the height of the work frame needs to be adjusted to a suitable position, the rack is first driven upward by the meshing transmission of gears to lift the work frame and achieve a quick coarse adjustment. When the work frame is close to the position, the worm gear drives the worm wheel to rotate, and the worm wheel drives the lead screw to rotate, causing the support column to move upward along the lead screw to continue to raise the work frame and achieve a fine adjustment. The combination of coarse and fine adjustment can quickly adjust to a suitable position, improve production efficiency, and meet the needs of users.

[0023] 2. In this utility model, after the height of the work frame is adapted to a product, the positioning mechanism is raised first, and the positioning clamps on both sides are placed above the work frame. Then, the rotating wheel drives the bidirectional threaded rod to rotate, so that the positioning clamps on both sides move closer to the center together, thereby applying a squeezing force to the sandwich panel by the positioning clamps on both sides, and then fixing the positioning mechanism. When the height of the work frame changes, it can quickly move back to the original position through the position of the positioning mechanism. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a pad printing machine worktable height fine-tuning component, including a sandwich plate 1, a base plate 3 fixedly connected to the bottom of the sandwich plate 1 for supporting other components, a support shell 4 fixedly connected to the top of the base plate 3, a rack 5 slidably connected to the left side inside the support shell 4, the top of the rack 5 penetrating the support shell 4 and being able to slide up and down through the top of the support shell 4, a transmission rod 6 rotatably connected to the upper front side of the support shell 4, a gear 7 fixedly connected to the rear end of the transmission rod 6 penetrating the support shell 4, rotating the transmission rod 6 to drive the gear 7 to rotate, the left side of the gear 7 meshing with the rack 5, the gear 7 driving the rack 5 to move through meshing transmission, a housing 8 fixedly connected to the top of the rack 5, a rotating rod 9 rotatably connected to the bottom outer side of the housing 8, and a worm gear 1 fixedly connected to the rear end of the rotating rod 9 penetrating the housing 8. 0. The worm gear 10 is rotated by rotating the rotating rod 9. The lead screw 11 is rotatably connected inside the housing 8. The worm wheel 12 is fixedly connected to the bottom outer side of the lead screw 11. The worm wheel 12 is meshed with the worm gear 10. The support column 13 is threadedly connected to the top outer side of the lead screw 11. The height of the support column 13 can be finely adjusted by the lead screw 11. The top of the support column 13 passes through the housing 8 and is fixedly connected to the work frame 14. The work frame 14 is used to place products. The pull rod 16 is slidably connected to the upper right side of the support housing 4. The pull rod 16 passes through the support housing 4 and is fixedly connected to the internal gear ring 17. The internal gear ring 17 is meshed with the gear 7. The rotation of the gear 7 is limited by the internal gear ring 17. A spring 18 is provided on the outer side of the left end of the pull rod 16. The left end of the spring 18 is fixedly connected to the internal gear ring 17. The other end of the spring 18 is fixedly connected to the support housing 4.

[0033] Specifically, when the device needs to be adjusted to suit the required height of the product, first pull the lever 16, which moves the internal gear ring 17 to the right, disengaging it from the limiting action on the gear 7. Simultaneously, the spring 18 is compressed. Then, the rotation of the transmission rod 6 drives the rotation of the gear 7. Through meshing transmission, the gear 7 causes the rack 5 to slide upwards within the support housing 4. The rising rack 5 pushes the housing 8, thereby lifting the work frame 14, quickly bringing it close to the required height of the product, reducing the height adjustment time. Once the approximate height is reached, release the lever. Rod 16 and spring 18 will reset to re-engage the internal gear ring 17 with gear 7, restricting the rotation of gear 7 and preventing rack 5 from slipping. Then, by rotating rod 9, rod 9 drives worm 10 to rotate. Worm 10 drives worm wheel 12 to rotate together through meshing transmission. When worm wheel 12 rotates, it will drive lead screw 11 to rotate together. Support column 13 is threadedly connected to lead screw 11. Therefore, when lead screw 11 rotates, support column 13 will move along lead screw 11, further lifting the work frame 14 to achieve precise adjustment of the height of work frame 14.

[0034] Reference Figure 1 , Figure 4 and Figure 5The positioning mechanism 2 includes a bidirectional threaded rod 201, which is located in the upper middle part of the inner side of the sandwich panel 1. A groove 202 is provided on the rear side of the inner wall of the sandwich panel 1. A slider 204 is slidably connected inside the groove 202. The slider 204 slides up and down inside the groove 202. A positioning rod 203 is fixedly connected to the bottom of the groove 202. The top end of the positioning rod 203 passes through the slider 204. The positioning rod 203 guides and limits the slider 204. Positioning clamps 205 are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod 201. The positioning clamps 205 on both sides can move in opposite directions by rotating the bidirectional threaded rod 201. A rotating wheel 206 is fixedly connected to the right side of the outer wall of the bidirectional threaded rod 201. A knob 21 is fixedly connected to the front end of the rotating rod 9. The size of the positioning clamp 205 matches the internal size of the sandwich panel 1.

[0035] Specifically, after adjusting the height of the work frame 14 to suit the product, the positioning mechanism 2 is moved upward to be above the work frame 14. Then, the rotating wheel 206 drives the rotation of the bidirectional threaded rod 201. The positioning clamp 205 can slide on the inner side of the sandwich plate 1 through the rotation of the bidirectional threaded rod 201. As the bidirectional threaded rod 201 rotates, the positioning clamps 205 on both sides move closer to each other along the bidirectional threaded rod 201. When the positioning clamp 205 reaches above the work frame 14, the positioning mechanism 2 is adjusted so that the positioning clamp 205 contacts the work frame 14. The rotating wheel 206 is rotated to make the positioning clamps 205 on both sides move closer. As the positioning clamp 205 gradually approaches, it will apply a squeezing force to the sandwich plate 1, thereby firmly clamping the positioning mechanism 2 on the sandwich plate 1. When the height of the work frame 14 needs to be adjusted, the position of the positioning clamp 205 makes it convenient for the work frame 14 to be adjusted without recalibrating the height, avoiding deviations that may occur when the operator adjusts it manually. The knob 21 is convenient for rotating the rotating rod 9.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The front left and right sides of the mezzanine plate 1 are fixedly connected with slide rails 15. The left and right ends of the work frame 14 are slidably connected inside the corresponding slide rails 15. The work frame 14 is further fixed by the slide rails 15. The front right side of the mezzanine plate 1 is provided with a scale 19. By observing the scale 19, the product height can be more specific. The right rear side of the work frame 14 is fixedly connected with a pointer 20.

[0037] Specifically, the work frame 14 can slide up and down more stably under the limit of the slide rail 15. As the work frame 14 slides, the scale 19 pointed to by the pointer 20 can be observed more intuitively to understand the height position, which makes it easier to accurately fix the required height of the product.

[0038] Reference Figure 1 and Figure 2A handwheel 22 is fixedly connected to the front end of the transmission rod 6. An anti-slip sleeve 23 is fixedly connected to the front outer wall of the handwheel 22. The anti-slip sleeve 23 plays an anti-slip role when the handwheel 22 is turned. Support legs 24 are fixedly connected to the four corners of the bottom of the base plate 3. Shock-absorbing pads 25 are fixedly connected to the bottom of the multiple support legs 24.

[0039] Specifically, the handwheel 22 makes it easier to rotate the transmission rod 6. When rotating, the anti-slip sleeve 23 prevents slipping due to wet hands. The support leg 24 at the bottom supports the overall structure of the device. The shock-absorbing pad 25 reduces the noise generated by the device during operation.

[0040] Working principle: When the device needs to be adapted to the required height of the product, firstly, pull the lever 16 to move the internal gear ring 17 to the right, causing the internal gear ring 17 to disengage from the limit of the gear 7. At the same time, the spring 18 is compressed and contracted. Then, through the rotation transmission rod 6, the gear 7 is driven to rotate. The gear 7 then meshes and drives the rack 5 to slide upward inside the support shell 4. The upward movement of the rack 5 pushes the shell 8 upward, thereby lifting the work frame 14, allowing the work frame 14 to quickly approach the required height of the product, greatly saving adjustment time. At this time, release the lever 16, and the spring 18... The internal gear ring 17 is re-engaged with the gear 7 to limit the rotation of the gear 7 and prevent the rack 5 from sliding downward. Then, the rotating rod 9 is rotated to drive the worm 10 to rotate. The worm 10 then drives the worm wheel 12 to rotate together through meshing transmission. When the worm wheel 12 rotates, it drives the lead screw 11 to rotate together. The support column 13 is threadedly connected to the lead screw 11. When the lead screw 11 rotates, the support column 13 will move along the lead screw 11. After the support column 13 moves, it will continue to lift the work frame 14, so as to achieve fine adjustment of the height of the work frame 14.

[0041] After the work frame 14 is adapted to the height of the product, the positioning mechanism 2 is moved upward until it is above the work frame 14. Then, the rotating wheel 206 drives the bidirectional threaded rod 201 to rotate. The positioning clamp 205 can slide on the inner side of the sandwich plate 1 through the rotation of the bidirectional threaded rod 201. As the bidirectional threaded rod 201 rotates, the two positioning clamps 205 can move closer to each other along the bidirectional threaded rod 201. After the positioning clamp 205 reaches above the work frame 14, the positioning mechanism 2 is adjusted to the position where the positioning clamp 205 contacts the work frame 14. The rotating wheel 206 is turned to make the two positioning clamps 205 move closer to each other. As the two positioning clamps 205 gradually approach each other, they exert a squeezing force on the sandwich plate 1, thereby fixing the positioning mechanism 2 on the sandwich plate 1. When the height of the work frame 14 is adjusted, the position of the positioning clamp 205 can be used to adjust the height without recalibrating it, avoiding deviations when the operator adjusts it manually.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
