Description

Technical Field

[0001] The present invention relates to the technical field of glass bottle production technology, in particular to a UV follow-up silk-screen printing mechanism. Background Art

[0002] In the production process of glass bottles, screen printing is often used to print the bottle body. In the existing technology, each glass bottle is mostly printed centrally and then UV cured uniformly. This requires the glass bottles to be transferred from the screen printing station to the curing station, which is inefficient.

[0003] To this end, the applicant disclosed a silk screen assembly in the patent publication number "CN218228283U", Figure 1 In this patent, the UV curing lamp is integrated with the glass bottle screen printing station, and a mounting base is used to install the glass bottle body to be processed. The general screen printing equipment is located above the bottle body. After the screen printing equipment is completed, the bottle body is directly swung down to the UV curing lamp for curing using a swing assembly. That is, there is no need for transportation, and it can be directly cured after screen printing, which solves the above problem well.

[0004] However, in the technical solution of this patent, the glass bottle is clamped together by the fixed end and the movable end of the mounting seat, and the glass bottle is usually grabbed by a robot arm from the previous workstation to this workstation. When installing the glass bottle to this workstation, it is necessary to make one end of the glass bottle abut and be concentric with the fixed end, and then move the movable end to press against the other end of the glass bottle. Since the glass bottle does not have any support measures, the robot arm cannot release the glass bottle before the fixed end and the movable end jointly clamp the glass bottle. This requires that the installation and debugging accuracy of each equipment is very high, otherwise the robot arm needs to be operated repeatedly, which is inefficient; and it is easy for the glass bottle to be not concentric with the fixed end and the movable end, resulting in the glass bottle not being installed in place, which in turn affects the silk screen printing. If a supporting component is directly added, it will bring about derivative problems such as affecting the rotation of the glass bottle and blocking the UV curing lamp. Therefore, how to provide a UV follow-up silk screen printing mechanism with a supporting component to solve the above-mentioned defects of the prior art and solve the derivative problems brought about by the addition of supporting components is a technical problem that needs to be solved urgently in this field.

DETAILED DESCRIPTION

[0025] A UV follow-up screen printing mechanism includes a mounting base and a UV curing lamp 4. The mounting base has a rotatable fixed end 5 and a movable end 6 that can move closer to or away from the fixed end 5. The bottom of the fixed end 5 is fixedly connected to a crossbeam 10, and the movable end 6 is slidably connected to the crossbeam 10 through a connecting bracket 13; the UV curing lamp 4 is arranged on one side of the mounting base and can swing relative to the mounting base. The above are all existing technologies. In actual applications, as with the existing technology, rotating shafts 3 are provided on both sides of the fixed end 5 of the mounting base. The rotating shafts 3 are rotatably arranged on the fixed bracket, and the rotating shafts 3 are driven by the first drive motor 2 to drive the mounting base to rotate, thereby realizing the relative rotation of the UV curing lamp 4 relative to the mounting base. At the same time, the fixed end 5 of the mounting base is driven to rotate by the second drive motor, thereby realizing the rotation of the glass bottle 7.

[0026] The present invention is improved on the basis of the prior art. Figure 2-6 In the present invention, the movable end 6 is elastically connected to the connecting bracket 13 so that the connecting bracket 13 can move a certain distance after the movable end 6 is pressed against the glass bottle 7. A driving component 9 and a supporting component 8 for supporting the glass bottle 7 are provided above the crossbeam 10. The supporting component 8 is slidably arranged on the crossbeam 10 up and down. The driving component 9 is fixedly connected to the connecting bracket 13 and is configured to drive the supporting component 8 to descend when the connecting bracket 13 continues to move after the movable end 6 is pressed against the glass bottle 7.

[0027] It is worth noting that the present invention adds a supporting component 8 for supporting the glass bottle 7, which solves the defects of the prior art. However, the addition of the supporting component 8 will bring new derivative problems, such as affecting the rotation of the glass bottle 7 and blocking the UV curing lamp 4. The present invention solves the above-mentioned derivative problems by making the movable end 6 close to the glass bottle 7 and the connecting bracket 13 can be moved a certain distance, and then cooperating with the provided driving component 9, the supporting component 8 can be lowered after the movable end 6 and the fixed end 5 clamp the glass bottle 7.

[0028] In this embodiment, a bottom support plate 11 is provided below the crossbeam 10, and a reset spring 12 is connected between the bottom support plate 11 and the support component 8 for causing the support component 8 to reset. The setting of the reset spring 12 can enable the support component 8 to be raised before the conical head 601 is separated from the glass bottle 7 after the solidification is completed, so as to support the glass bottle 7 and facilitate the removal of the item.

[0029] There is no specific restriction on the fixed end 5 of the mounting seat, and the existing technology can be used. The movable end 6 has been improved as follows: Specifically, the movable end 6 of this embodiment includes a conical head 601 and a connecting shaft 602, and a mounting box 604 is provided on the top of the connecting bracket 13. At least two needle bearings 605 are provided in the mounting box 604. The connecting shaft 602 is passed through the needle bearing 605 and can be rotated and moved axially. The conical head 601 is fixedly connected to one end of the connecting shaft 602; a positioning bearing 606 is provided inside the mounting box 604, and the other end of the connecting shaft 602 passes through the positioning bearing 606 and is connected to a stop head 603, and a stop ring 608 is provided on the side of the positioning bearing 606 away from the stop head 603, and a stop platform 6021 is provided in the middle of the connecting shaft 602, and a buffer spring 607 is provided between the stop ring 608 and the stop platform 6021.

[0030] When the conical head 601 is not working, under the action of the buffer spring 607, the stopper 603 is against the positioning bearing 606. After the conical head 601 is in contact with the mouth of the glass bottle 7, the movable end 6 continues to move and the buffer spring 607 is compressed. The stopper 603, the connecting shaft 602 and the conical head 601 move to the left side of the figure relative to the mounting box 604.

[0031] As in the prior art, the movement of the movable end 6 is achieved by the movement of the connecting bracket 13. In this embodiment, the solid line of the connecting bracket 13 is achieved in the following manner. Figure 3 and Figure 6 , the cross section of the cross beam 10 perpendicular to the length direction of this embodiment is U-shaped. Since the support component 8 can slide up and down, it will occupy a certain space inside the cross beam 10. Therefore, the connecting bracket 13 of this embodiment is arranged on the left side of the support component 8. Specifically, a slide rail 18 is provided on the left side of the support component 8 inside the cross beam 10. The first slide 14 is provided on the slide rail 18. The connecting bracket 13 is fixedly connected to the first slide 14 and moves left and right following the sliding of the first slide 14; at the same time, a driving screw is provided on the right side of the support component 8 inside the cross beam 10. The driving screw is connected to a third driving motor 17 that drives it to rotate. The second slide 15 is threadedly engaged with the screw. The second slide 15 is against the inner wall of the cross beam 10 and cannot rotate. The rotation of the driving screw can drive the second slide 15 to move. The second slide 15 is fixedly connected to a pull rod 16. The pull rod 16 extends to the first slide 14 and is fixedly connected to the first slide 14, so that when the second slide 15 moves, the first slide 14 is driven to move.

[0032] The support member 8 of this embodiment includes a support plate 801 and at least two supports 802. The support plate 801 is slidably disposed within the crossbeam 10. The two supports 802 are disposed on top of the support plate 801. The tops of the supports 802 are provided with V-shaped support portions 8021 for supporting the glass bottles 7. The bottom support plate 11 is fixedly connected to the bottom of the crossbeam 10. A return spring 12 is disposed between the support plate 801 and the bottom support plate 11. Furthermore, sliders 8011 are disposed on both sides of the support plate 801. A baffle is disposed within the crossbeam 10 to abut against both sides of the support plate 801. Slideways for guiding the sliders 8011 are disposed at corresponding positions on the baffle and the top of the crossbeam 10. The tops of the slideways are sealed. It is worth noting that this arrangement prevents the supports 802 and support plate 801 from slipping off the crossbeam 10.

[0033] On the basis of the above, the V-shaped support portion 8021 is provided with a support roller 803. It is easy to understand that the support roller 803 can rotate, thereby reducing the friction between the glass bottle 7 and the V-shaped support portion 8021 when the conical head 601 pushes the glass bottle 7, thereby avoiding damage to the glass bottle 7.

[0034] In this embodiment, the driving component 9 includes a connecting arm 901, one end of which is fixedly connected to the connecting bracket 13, and the other end of the connecting arm 901 is provided with an extrusion member 902. The support 802 is provided with a hollow groove 8022 inside, and a pressure block 8023 is provided at the bottom of the hollow groove 8022. The pressure block 8023 is provided with a slope that gradually increases in the direction away from the driving component 9. It is worth noting that, after the conical head 601 contacts the mouth of the glass bottle 7, as the connecting bracket 13 continues to move, the extrusion member 902 contacts the slope of the pressure block 8023, gradually pressing the support 802 downward, thereby lowering the supporting component 8 away from the glass bottle 7.

[0035] In this embodiment, the extrusion member 902 is a rotatable roller. This configuration can reduce the friction between the extrusion member 902 and the pressure block 8023, thereby facilitating the movement of the extrusion member 902.

[0036] It is worth noting that in other embodiments of the present invention, the driving component 9 can also drive the support component 8 to descend in other ways. For example, in some embodiments, the above-mentioned extrusion member 902 and the pressure block 8023 are not required. The driving component 9 includes two connecting rods, named as the first connecting rod and the second connecting rod. One end of the first connecting rod is fixedly connected to the connecting bracket 13, and one end of the second connecting rod is hinged to the support component 8, and the other end is hinged to the other end of the first connecting rod. With this arrangement, the first connecting rod can also drive the support component 8 to descend when moving with the connecting bracket 13.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
