Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and more specifically, to a multi-head device and a method for adjusting the multi-head device. Background Technology

[0002] After installation, the relative positions of the printheads in a multi-head printing device may still have some deviation. If not adjusted in time, the products printed by this device may have major quality problems. However, it is generally difficult to readjust the position of each printhead after installation, so it is difficult to improve the quality of the printed products by adjusting the position of each printhead. Summary of the Invention

[0003] The purpose of this application is to provide a multi-nozzle device and a method for adjusting the multi-nozzle device in response to at least one of the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] One aspect of this application provides a multi-nozzle device, including a base plate, and adjustable nozzles, a reference nozzle, a translational adjustment assembly, and a rotational adjustment assembly, all mounted on the base plate. The adjustable nozzles and the reference nozzle are arranged in a first direction. The translational adjustment assembly is used to drive the adjustable nozzles to move relative to the reference nozzles in a second direction. The rotational adjustment assembly is used to drive the adjustable nozzles to pivot relative to the base plate. Both the first direction and the second direction are parallel to the surface of the base plate, and the first direction is perpendicular to the second direction. The adjustable nozzles are used to rotate in a plane parallel to the surface of the base plate.

[0006] Optionally, the translational adjustment assembly includes a first active adjustment unit and a first passive adjustment unit both mounted on the base plate. In the second direction, the first active adjustment unit abuts against one end of the adjustable nozzle, and the first passive adjustment unit abuts against the other end of the adjustable nozzle. The first active adjustment unit is used to move in the second direction to adjust the position of the adjustable nozzle in the second direction.

[0007] The beneficial effect of this technical solution is that the adjustable nozzle can be limited from both sides in the second direction, and the position of the adjustable nozzle can be linearly adjusted by the first active adjustment unit.

[0008] Optionally, the first active adjustment unit includes a push-pull bolt and a linear push block. A threaded hole is formed on the linear push block. The push-pull bolt is threadedly connected to the threaded hole. The push-pull bolt is mounted on the base plate and is used to pivot relative to the base plate to drive the linear push block to move relative to the base plate in the second direction.

[0009] The beneficial effect of this technical solution is that workers can use tools to apply force to the nut of the push-pull bolt to rotate the push-pull bolt, which will drive the linear push block connected to the thread of the push-pull bolt to move in the second direction, thereby realizing the adjustment of the position of the adjustable nozzle in the second direction, which is convenient for fine adjustment of the position of the adjustable nozzle in the second direction.

[0010] Optionally, the first active adjustment unit further includes a washer and a tension spring. The washer is fixed to the base plate and fitted onto the push-pull bolt to limit the relative position of the push-pull bolt and the base plate in the second direction. The tension spring is fitted onto the push-pull bolt, with one end of the tension spring abutting against the washer and the other end of the tension spring abutting against the linear push block.

[0011] The beneficial effect of this technical solution is that it makes the linear push block, push-pull bolt, washer and base plate fit together tightly, thereby making the limit of the adjustable nozzle by the first active adjustment unit more stable.

[0012] Optionally, a V-shaped groove is formed on the adjustable nozzle, the opening of the V-shaped groove facing the linear push block, the V-shaped groove having two sidewalls inclined relative to the second direction, and the linear push block abutting against both sidewalls.

[0013] The beneficial effect of this technical solution is that, through the contact between the two side walls of the V-shaped groove and the linear push block, the linear push block defines the position of the adjustable nozzle in the first direction and the second direction.

[0014] Optionally, the rotation adjustment assembly includes a second active adjustment unit and a second passive adjustment unit. The second active adjustment unit includes an active push rod, and the second passive adjustment unit includes a passive push rod. Both the active push rod and the passive push rod are pivotally connected to the base plate. In the first direction, the active push rod abuts against one side of the adjustable nozzle, and the passive push rod abuts against the other side of the adjustable nozzle. The active push rod is used to pivot relative to the base plate to drive the adjustable nozzle to pivot relative to the base plate.

[0015] The beneficial effects of this technical solution are as follows: In this way, the adjustable nozzle can be limited in the second direction by the second active adjustment unit and the second passive adjustment unit. When the active push rod is rotated, the active push rod pushes the adjustable nozzle to rotate, thereby adjusting the position of the active push rod. When both the reference nozzle and the adjustable nozzle are straight, the adjustable nozzle can be rotated so that the length direction of the adjustable nozzle is parallel to the length direction of the reference nozzle.

[0016] Optionally, the second active adjustment unit further includes an adjustment bolt. The active push rod includes a first rod portion and a second rod portion that are perpendicularly connected to each other. The first rod portion is arranged parallel to the first direction, and the second rod portion is arranged parallel to the second direction. The second rod portion abuts against the adjustable nozzle in the first direction. The adjustment bolt is threadedly connected to the base plate, and the adjustment bolt abuts against the first rod portion in the second direction.

[0017] The beneficial effect of this technical solution is that when the adjusting bolt is rotated to push the first rod in the second direction, the active push rod pivots, causing the second rod to push the adjustable nozzle to pivot. In this embodiment, the length of the first rod is preferably twice the length of the second rod.

[0018] Optionally, the second driven adjustment unit further includes an elastic limiting member, and the driven push rod is used to cooperate with the elastic limiting member to make the driven push rod contact the adjustable nozzle pressure.

[0019] The beneficial effect of this technical solution is that the elastic limiting member provides elastic force to the driven push rod, so that the driven push rod limits the position of the adjustable nozzle under the action of the elastic force, and the second active push rod and the driven push rod can clamp the adjustable nozzle under the action of the elastic force.

[0020] Optionally, the multi-nozzle device provided in this application includes two adjustable nozzles, two translational adjustment components, and two rotational adjustment components. In the first direction, the reference nozzle is located between the two adjustable nozzles. The two translational adjustment components are correspondingly matched with the two adjustable nozzles, and the two rotational adjustment components are correspondingly matched with the two adjustable nozzles.

[0021] The beneficial effect of this technical solution is that the position of each adjustable nozzle can be adjusted based on the reference nozzle.

[0022] Another aspect of this application provides an adjustment method for a multi-nozzle device, implemented using the multi-nozzle device provided in this application. The translational adjustment assembly includes a first active adjustment unit, which includes a push-pull bolt. The rotational adjustment assembly includes a second active adjustment unit, which further includes an adjustment bolt. The adjustment method includes:

[0023] Tighten the push-pull bolt to align the two ends of the adjustable nozzle with the two ends of the reference nozzle in the second direction;

[0024] Tighten the adjusting bolt to pivot the adjustable nozzle until the length direction of the adjustable nozzle is parallel to the length direction of the reference nozzle.

[0025] The technical solution provided in this application can achieve at least one of the following beneficial effects:

[0026] The multi-nozzle device and its adjustment method provided in this application connect to external equipment via a base plate, adjust the relative position of the adjustable nozzle and the reference nozzle in a second direction via a translational adjustment component, and pivot the adjustable nozzle by rotating the adjustment component to adjust the relative angle between the adjustable nozzle and the reference nozzle. This enables the multi-nozzle device provided in this application to adjust the relative position between the adjustable nozzle and the reference nozzle, thereby improving the quality of the printed products.

[0046] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] like Figures 1 to 5 As shown, one aspect of this application provides a multi-nozzle device, including a base plate 06, and adjustable nozzles 01, reference nozzles 03, a translational adjustment assembly, and a rotational adjustment assembly, all mounted on the base plate 06. The adjustable nozzles 01 and the reference nozzles 03 are arranged in a first direction. The translational adjustment assembly is used to drive the adjustable nozzles 01 to move relative to the reference nozzles 03 in a second direction. The rotational adjustment assembly is used to drive the adjustable nozzles 01 to pivot relative to the base plate 06. Both the first direction and the second direction are parallel to the surface of the base plate 06, and the first direction is perpendicular to the second direction. The adjustable nozzles 01 are used to rotate in a plane parallel to the surface of the base plate.

[0050] The multi-nozzle device provided in this application connects to external equipment via a base plate 06. A translational adjustment assembly adjusts the relative position of the adjustable nozzle 01 and the reference nozzle 03 in a second direction. Rotating the adjustment assembly causes the adjustable nozzle 01 to pivot, thereby adjusting the relative angle between the adjustable nozzle 01 and the reference nozzle 03. This enables the multi-nozzle device to adjust the relative position between the adjustable nozzle 01 and the reference nozzle 03, and improves the quality of products printed by the printing equipment through this adjustment.

[0051] Optionally, the translational adjustment assembly includes a first active adjustment unit 02 and a first passive adjustment unit 09, both mounted on the base plate 06. In the second direction, the first active adjustment unit 02 abuts against one end of the adjustable nozzle 01, and the first passive adjustment unit 09 abuts against the other end of the adjustable nozzle 01. The first active adjustment unit 02 is used to move in the second direction to adjust the position of the adjustable nozzle 01 in the second direction. This allows the adjustable nozzle 01 to be limited from both sides in the second direction, and its position can be linearly adjusted by the first active adjustment unit 02. Alternatively, the first active adjustment unit 02 and the first passive adjustment unit 09 can be positioned on the same side of the adjustable nozzle 01 in the second direction, and the first passive adjustment unit 09 can be a spring connected to both the base plate 06 and the adjustable nozzle 01, stretching when the first active adjustment unit 02 pushes the adjustable nozzle 01.

[0052] Optionally, the first active adjustment unit 02 includes a push-pull bolt 16 and a linear push block 20. A threaded hole is formed on the linear push block 20, and the push-pull bolt 16 is threadedly connected to the threaded hole. The push-pull bolt 16 is mounted on the base plate 06 and is used to pivot relative to the base plate 06 to drive the linear push block 20 to move relative to the base plate 06 in the second direction. Thus, the operator can use a tool to apply force to the nut 05 of the push-pull bolt 16 to rotate the push-pull bolt 16, causing the linear push block 20, which is threadedly connected to the push-pull bolt 16, to move in the second direction, thereby adjusting the position of the adjustable nozzle 01 in the second direction, facilitating fine-tuning of the position of the adjustable nozzle 01 in the second direction.

[0053] Optionally, the first active adjustment unit 02 further includes a washer 17 and a tension spring 19. The washer 17 is fixed to the base plate 06 and is fitted onto the push-pull bolt 16 to limit the relative position of the push-pull bolt 16 and the base plate 06 in the second direction. The tension spring 19 is fitted onto the push-pull bolt 16, with one end of the tension spring 19 abutting against the washer 17 and the other end abutting against the linear push block 20. This ensures a tight fit between the linear push block 20, the push-pull bolt 16, the washer 17, and the base plate 06, thereby making the limiting of the adjustable nozzle 01 by the first active adjustment unit 02 more stable. In this embodiment of the application, preferably, a groove extending in the second direction is formed on the base plate 06. A linear push block 20 is disposed in the groove and slides in cooperation with the groove in the second direction. One end of the groove extends to the end face of the base plate 06. A washer 17 is installed at the end. The nut 05 of the push-pull bolt 16 can be operated at the end. A pressure plate 04 is provided on the base plate 06. The washer 17 is fixed to the base plate 06 by the pressure plate 04. The first driven adjustment unit 09 includes a pressure spring. One end of the pressure spring abuts against the base plate 06 in the second direction, and the other end abuts against the adjustable nozzle 01. Of course, the first driven adjustment unit 09 can also include a push rod, and the pressure spring is mounted on the push rod. The push rod is used to move relative to the base plate 06 in the second direction. The push rod abuts against the adjustable nozzle 01 to compress the pressure spring. In this embodiment of the application, preferably, the bottom ends of the adjustable nozzle 01 and the reference nozzle 03 are disposed in the groove. A spring plunger 07 is also disposed on the base plate 06. The spring plunger 07 is inserted into the groove from the end face of the base plate 06 in the second direction. Since the linear push block 20 needs to be clearance-fitted with the inner wall of the slide groove in order to move the linear push block 20 relative to the slide groove in the second direction, after the position of the adjustable nozzle in the second direction is completed, the spring plunger 07 can be operated to move the spring plunger 07 in the second direction until the linear push block 20 is close to the groove opening on the base plate.

[0054] Optionally, a V-groove 14 is formed on the adjustable nozzle 01, with the opening of the V-groove 14 facing the linear push block 20. The V-groove 14 has two sidewalls inclined relative to the second direction, and the linear push block 20 abuts against both sidewalls. Thus, through the contact between the two sidewalls of the V-groove 14 and the linear push block 20, the linear push block 20 defines the position of the adjustable nozzle 01 in the first direction and the second direction. It is understood that the straight line formed by the intersection of the two sidewalls intersects the axis of the push-pull bolt 16, and the two sidewalls are symmetrically arranged relative to the axis of the push-pull bolt 16.

[0055] Optionally, the rotation adjustment assembly includes a second active adjustment unit and a second passive adjustment unit. The second active adjustment unit includes an active push rod 10, and the second passive adjustment unit includes a passive push rod 08. Both the active push rod 10 and the passive push rod 08 are pivotally connected to the base plate 06. In the first direction, the active push rod 10 abuts against one side of the adjustable nozzle 01, and the passive push rod 08 abuts against the other side of the adjustable nozzle 01. The active push rod 10 is used to pivot relative to the base plate 06 to drive the adjustable nozzle to pivot relative to the base plate 06. In this way, the second active adjustment unit and the second passive adjustment unit can limit the adjustable nozzle 01 in the second direction. When the active push rod 10 is rotated, the active push rod 10 pushes the adjustable nozzle 01 to rotate, thereby adjusting the position of the active push rod 10. When both the reference nozzle 03 and the adjustable nozzle 01 are linear, the adjustable nozzle 01 is rotated so that the length direction of the adjustable nozzle 01 is parallel to the length direction of the reference nozzle 03. In this embodiment, the adjustable nozzle 01 can be pivotally connected to the base plate 06 via a pivot shaft; when the adjustable nozzle 01 has the above-mentioned V-groove 14, the end of the straight push block 20 that contacts the side wall of the V-groove 14 can be an arc-shaped end 18. When the adjustable nozzle 01 pivots, the two side walls of the V-groove 14 slide in cooperation with the arc-shaped end 18.

[0056] Optionally, the second active adjustment unit further includes an adjusting bolt 11. The active push rod 10 includes a first rod portion 12 and a second rod portion 13 connected perpendicularly to each other. The first rod portion 12 is arranged parallel to the first direction, and the second rod portion 13 is arranged parallel to the second direction. The second rod portion 13 abuts against the adjustable nozzle 01 in the first direction. The adjusting bolt 11 is threaded to the base plate 06, and the adjusting bolt 11 abuts against the first rod portion 12 in the second direction. Thus, when the adjusting bolt 11 is rotated to push the first rod portion 12 in the second direction, the active push rod 10 pivots, causing the second rod portion 13 to push the adjustable nozzle 01 to pivot. In this embodiment, the length of the first rod portion 12 is preferably twice the length of the second rod portion 13.

[0057] Optionally, the second driven adjustment unit further includes an elastic limiting member 15, and the driven push rod 08 is used to cooperate with the elastic limiting member 15 to make the driven push rod 08 pressurize the adjustable nozzle 01. In this way, the elastic limiting member 15 provides elastic force to the driven push rod 08, so that the driven push rod 08 limits the position of the adjustable nozzle 01 under the action of the elastic force, and under the action of the elastic force, the second active push rod 10 and the driven push rod 08 can clamp the adjustable nozzle 01. In this embodiment, the elastic limiting member 15 can be a pressure spring mounted on the base plate 06. This pressure spring makes pressure contact with the driven push rod 08, thereby causing the driven push rod 08 to make pressure contact with the adjustable nozzle 01. Alternatively, the elastic limiting member 15 can be a torsion spring. The driven push rod 08 is pivotally connected to the base plate 06 via a rotating shaft, which is fixed to the base plate 06. The torsion spring is fitted onto the rotating shaft, with one end fixed to the shaft and the other end fixed to the driven push rod 08. The torsion spring provides a torsional force to the driven push rod 08, causing it to make pressure contact with the adjustable nozzle 01. In this embodiment, the surface of the adjustable nozzle 01 that contacts the second rod portion 13 is parallel to the second direction, and the surface of the adjustable nozzle 01 that contacts the driven push rod 08 is also parallel to the second direction. This prevents the second active push rod 10 and the driven push rod 08 from obstructing the movement of the adjustable nozzle 01 in the second direction.

[0058] Optionally, the multi-nozzle device provided in this application embodiment includes two adjustable nozzles 01, two translational adjustment components, and two rotational adjustment components. In the first direction, the reference nozzle 03 is located between the two adjustable nozzles 01. The two translational adjustment components are correspondingly engaged with the two adjustable nozzles 01, and the two rotational adjustment components are also correspondingly engaged with the two adjustable nozzles 01. Thus, the position of each adjustable nozzle can be adjusted relative to the reference nozzle 03. In this application embodiment, the number of adjustable nozzles 01 can also be 3 to 5, for example, 3, 4, or 5.

[0059] like Figure 6 As shown, another aspect of this application provides an adjustment method for a multi-nozzle device, implemented using the multi-nozzle device provided in the embodiments of this application. The translational adjustment assembly includes a first active adjustment unit, which includes a push-pull bolt. The rotational adjustment assembly includes a second active adjustment unit, which further includes an adjustment bolt. The adjustment method includes:

[0060] Step 100: Tighten the push-pull bolt to align the two ends of the adjustable nozzle with the two ends of the reference nozzle in the second direction;

[0061] Step 200: Tighten the adjusting bolt to pivot the adjustable nozzle until the length direction of the adjustable nozzle is parallel to the length direction of the reference nozzle.

[0062] In this embodiment of the application, preferably, rotating the adjusting bolt one revolution moves the end of the adjustable nozzle by 0.25 mm.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
