Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and in particular to a glue application machine. Background Technology

[0002] Currently, many plate-shaped or sheet-shaped objects require adhesive to be applied to their surfaces. In order to automate the adhesive application process, patent publication document CN205887321U discloses a commonly used adhesive application machine. However, this type of adhesive application machine has a problem during operation: the adhesive head cannot be raised or lowered. Therefore, when applying adhesive to samples of different thicknesses, the samples must be raised before the adhesive application can be performed. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a glue-applying machine that allows the brush head to move in any direction relative to the base in three-dimensional space. The brush head's position relative to the base can be adjusted as needed to ensure that the brush head can adapt to the application of samples of different thicknesses.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A glue-applying machine includes a support platform and a gantry frame. The support platform is disposed below the gantry frame. A first-direction rack is disposed on the gantry frame. A mounting platform is slidably disposed on the gantry frame. A first drive motor is disposed on the mounting platform. The first drive motor meshes with the first-direction rack through a linkage rod and a gear. The machine also includes a lifting platform. A second drive motor is disposed on the lifting platform. A second-direction rack is disposed on the mounting platform. The second drive motor meshes with the second-direction rack through a linkage rod and a gear. A third-direction rack is disposed on the lifting linkage. A lifting linkage is slidably disposed on the lifting platform. A third drive motor on the lifting platform meshes with the third-direction rack through a gear. A brush head is disposed at one end of the lifting linkage.

[0006] In this type of glue application machine, a support platform is set below the gantry frame to place the items to be printed (including but not limited to paper or film). After the items to be printed are placed on the platform, when the first drive motor runs, the mounting platform moves on the gantry frame; when the second drive motor runs, the lifting platform moves on the mounting platform; and when the third drive motor runs, the lifting linkage moves on the lifting platform. By setting the first, second, and third drive motors, this type of glue application machine ultimately realizes the movement of the brush head relative to the support platform in any direction in three-dimensional space. This allows the brush head to be adjusted relative to the support platform as needed, ensuring that the brush head can adapt to the coating of samples of different thicknesses.

[0007] Optionally, a clamping plate is provided at one end of the lifting linkage, and the brush head is detachably mounted on the clamping plate.

[0008] The brush head is installed using a clamp, which allows for detachable installation of the brush head. Different brush heads can be replaced as needed when performing different types of painting operations.

[0009] Optionally, a perforated plate is provided on the support platform, and the perforated plate is a planar perforated plate, and the lifting connecting rod is perpendicular to the perforated plate.

[0010] The specific function of the perforated plate is to support the printed items. Because the perforated plate is used to support the printed items, it can prevent the items from being attracted to the support platform due to static electricity.

[0011] Optionally, it also includes lifting cylinders and a first pressure rod. Both ends of the perforated plate are provided with lifting cylinders, and both ends of the first pressure rod are respectively engaged with the cylinder rods of the two lifting cylinders.

[0012] The distance between the first pressure bar and the perforated plate can be adjusted by the lifting amount of the lifting cylinder. When the item to be coated is a sheet-like material such as paper or cardboard, the lifting cylinder can be used to pull the first pressure bar down, so that the sheet-like material is clamped between the perforated plate and the first pressure bar, thereby improving the stability of the item during coating.

[0013] Optionally, the cylinder rod of the lifting cylinder is perpendicular to the first pressure rod, and the first pressure rod is parallel to the perforated plate.

[0014] Optionally, a second pressure rod is also included. Each end of the support platform is provided with a guide rail, and a slider is provided on the guide rail. The slider is located on both sides of the perforated plate. Each end of the second pressure rod is respectively engaged with a slider. The second pressure rod is parallel to the perforated plate.

[0015] Because the first pressure bar is installed in a way that is not movable relative to the perforated plate (but can be raised and lowered), a second pressure bar is further set. The second pressure bar is not raised and lowered relative to the perforated plate but can be moved. The second pressure bar can be moved to the required position as needed. Then, a soft rubber pad is embedded between the second pressure bar and the item, thereby ensuring that the printed item is pressed firmly onto the perforated plate in at least two places. This can further improve the stability during the coating process and the integrity of the pattern after coating.

[0016] Optionally, the first, second, and third racks are perpendicular to each other.

[0017] Optionally, a lifting support is provided at the bottom of the platform, and the lifting support is in contact with the ground.

[0018] The functions of the lifting support are twofold: first, to adjust the height of the bearing platform relative to the ground as needed; and second, to prevent the bearing platform from directly contacting the ground.

[0019] The beneficial effects of this utility model are: it enables the brush head to move in any direction in three-dimensional space relative to the base, and the brush head position relative to the base can be adjusted as needed to ensure that the brush head can adapt to the coating of samples of different thicknesses.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] As attached Figure 1 ~Appendix Figure 6 As shown, a glue application machine includes a support platform 2 and a gantry frame 3. The support platform 2 is located below the gantry frame 3. A first-direction rack 7 is provided on the gantry frame 3. A mounting platform 4 is slidably provided on the gantry frame 3. A first drive motor 9 is provided on the mounting platform 4. The first drive motor 9 is engaged with the first-direction rack 7 through a linkage rod 6 and a gear 8. The machine also includes a lifting platform 13. A second drive motor 21 is provided on the lifting platform 13. A second-direction rack 20 is provided on the mounting platform 4. The second drive motor 21 is engaged with the second-direction rack 20 through a linkage rod 6 and a gear 8. A third-direction rack 11 is provided on a lifting linkage 10. A lifting linkage 10 is slidably provided on the lifting platform 13. A third drive motor 12 on the lifting platform 13 is engaged with the third-direction rack 11 through a gear 8. A brush head 14 is provided at one end of the lifting linkage 10.

[0032] In this type of glue application machine, a support platform 2 is set below the gantry frame 3. The support platform 2 is used to place the items to be printed (including but not limited to paper or film). After the items to be printed are placed on the support platform 2, when the first drive motor 9 is running, the mounting platform 4 moves on the gantry frame 3. When the second drive motor 21 is running, the lifting platform 13 moves on the mounting platform 4. When the third drive motor 12 is running, the lifting linkage 10 moves on the lifting platform 13. In this type of glue application machine, by setting the first drive motor 9, the second drive motor 21, and the third drive motor 12, the brush head 14 can move in any direction in three-dimensional space relative to the support platform 2. This allows the position of the brush head 14 relative to the support platform 2 to be adjusted as needed, ensuring that the brush head 14 can adapt to the coating of samples of different thicknesses.

[0033] As attached Figure 1 ~Appendix Figure 6 As shown, a clamping plate 15 is provided at one end of the lifting rod 10, and the brush head 14 is detachably mounted on the clamping plate 15.

[0034] The brush head 14 is installed using a clamp 15. This allows the brush head 14 to be detached and installed, so that different brush heads 14 can be replaced as needed when performing different types of painting operations.

[0035] As attached Figure 1 ~Appendix Figure 6 As shown, a perforated plate 5 is provided on the support 2, and the perforated plate 5 is a planar perforated plate 5, with the lifting connecting rod 10 perpendicular to the perforated plate 5.

[0036] Specifically, the function of the perforated plate 5 is to support the printed items. Because the perforated plate 5 is used to support the printed items, it can prevent the items from being attracted to the support platform 2 due to static electricity.

[0037] As attached Figure 1 ~Appendix Figure 6 As shown, it also includes a lifting cylinder 18 and a first pressure rod 16. Both ends of the perforated plate 5 are provided with lifting cylinders 18, and both ends of the first pressure rod 16 are respectively engaged with the cylinder rods of the two lifting cylinders 18.

[0038] The distance between the first pressure rod 16 and the perforated plate 5 can be adjusted by the lifting amount of the lifting cylinder 18. When the item to be coated is a sheet-like object such as paper, the lifting cylinder 18 can be used to pull the first pressure rod 16 down, so that the sheet-like object is clamped between the perforated plate 5 and the first pressure rod 16, thereby improving the stability of the item during coating.

[0039] As attached Figure 1 ~Appendix Figure 6 As shown, the cylinder rod of the lifting cylinder 18 is perpendicular to the first pressure rod 16, and the first pressure rod 16 is parallel to the perforated plate 5.

[0040] As attached Figure 1 ~Appendix Figure 6 As shown, it also includes a second pressure rod 17. Each end of the support platform 2 is provided with a guide rail 22, and a slider 19 is provided on the guide rail 22. The slider 19 is located on both sides of the perforated plate 5. Each end of the second pressure rod 17 is respectively engaged with a slider 19. The second pressure rod 17 is parallel to the perforated plate 5.

[0041] The slider 19 slides on the guide rail 22. When the slider 19 slides on the guide rail 22, the second pressure rod 17 will slide relative to the perforated plate 5, and the sliding direction is parallel to the perforated plate 5. The second pressure rod 17 will not rise or fall relative to the perforated plate 5 during the sliding process.

[0042] Because the first pressure rod 16 is installed in a way that is not movable relative to the perforated plate 5 (but can be raised and lowered), a second pressure rod 17 is further provided. The second pressure rod 17 is not raised and lowered relative to the perforated plate 5 but can be moved. The second pressure rod 17 can be moved to the required position as needed. Then, a soft rubber pad is embedded between the second pressure rod 17 and the item, thereby ensuring that the printed item is pressed firmly on the perforated plate 5 in at least two places. This can further improve the stability during the coating process and the integrity of the pattern after coating.

[0043] As attached Figure 1 ~Appendix Figure 6 As shown, the first direction rack 7, the second direction rack 20, and the third direction rack 11 are in a mutually perpendicular state.

[0044] As attached Figure 1 ~Appendix Figure 6 As shown, a lifting support 1 is provided at the bottom of the pier 2, and the lifting support 1 is in contact with the ground.

[0045] The function of the lifting support 1 is twofold: first, to adjust the height of the support platform 2 relative to the ground as needed; and second, to prevent the support platform 2 from directly contacting the ground.

[0046] In order to prevent the brush head from touching the perforated plate 5, a sensor such as an optical distance sensor or an ultrasonic distance sensor can be installed on the clamping plate 15.

[0047] In order to ensure the stability of the adhesive during the application process, a temperature probe can be installed in the adhesive storage tank (located above the gantry, not shown in the attached diagram) connected to the brush head for temperature measurement.

[0048] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that 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, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
