Description

Technical Field

[0001] The utility model relates to the field of printing equipment, in particular to a printing automatic calibration heating platform. Background Art

[0002] With the continuous development of printing technology, medium and large flatbed printing equipment is becoming more and more perfect. Such equipment is mainly used for color printing patterns on flat printing media such as plates. Before starting printing, it is necessary to calibrate and position the printing medium on the printing platform, that is, to position the printing medium to the positioning point of the printing platform in the specified direction. In the existing technology, it is generally manually adjusted and checked whether the position of the printing medium is correct. Due to the randomness and instability of manual operation, the printing quality cannot be guaranteed and the work efficiency is low. Utility Model Content

[0003] In view of the above-mentioned problems, the purpose of the utility model is to provide a printing automatic calibration heating platform to achieve automatic calibration and positioning of the printing medium on the supporting platform, avoid the arbitrariness and instability of manual operation, ensure printing quality and improve work efficiency.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A printing automatic calibration heating platform comprises a supporting platform, a plurality of driving wheels, a first positioning component, and a second positioning component. The supporting platform comprises a first side and a second side adjacent to each other. The first positioning component and the second positioning component are respectively close to the first side and the second side. The driving wheel array is arranged on the supporting platform. The axial direction of the driving wheel has an angle with the first side and the second side. The driving wheel can drive the printing medium to move on the supporting platform.

[0006] During the printing process, the printing medium is placed on the support platform manually or by a conveying device. Driven by the driving wheel, the printing medium moves toward the first positioning component and the second positioning component. The first positioning component and the second positioning component are higher than the support plane of the support platform. When one side of the printing medium is close to one of the first positioning component and the second positioning component, its moving direction is limited by the positioning component that is attached, and it can only move along the direction of the positioning component. Finally, the other side of the printing medium is attached to the other positioning component. In this process, regardless of whether the printing medium initially placed on the support platform is distorted, it is conveyed by the driving wheel to reach the first positioning component and the second positioning component, and under the limiting effect of the first positioning component and the second positioning component, the two sides of the printing medium are attached to the first positioning component and the second positioning component at the same time, realizing the automatic calibration and positioning of the printing medium on the support platform, without the need for manual intervention to make further positioning adjustments, ensuring the printing quality, and improving the work efficiency.

[0007] Furthermore, the first positioning assembly includes a first driving member, a first positioning plate, and a plurality of first guide wheels. The first guide wheel array is disposed at the top of the first positioning plate. The first driving member is connected to the first positioning plate and can drive the first positioning plate to rise and fall.

[0008] The first positioning assembly not only plays a positioning role, but also plays a guiding role. In the initial state, the first positioning plate rises under the action of the first driving member, and its top end is higher than the supporting plane of the supporting platform, so that the printing medium is blocked when it moves to the first positioning assembly, playing a positioning role; the first guide wheel installed on the top of the first positioning plate plays a guiding role. After the printing medium contacts the first guide wheel, it continues to move. The first guide wheel can rotate to reduce the friction of the fixed movement of the printing medium, making its movement more stable.

[0009] Furthermore, the second positioning assembly includes a second driving member, a second positioning plate, and a plurality of second guide wheels. The second guide wheel array is disposed at the top of the second positioning plate. The second driving member is connected to the second positioning plate and can drive the second positioning plate to rise and fall.

[0010] The second positioning assembly not only plays a positioning role, but also plays a guiding role. In the initial state, the second positioning plate rises under the action of the second driving member, and its top end is higher than the supporting plane of the supporting platform, so that the printing medium is blocked when it moves to the second positioning assembly, playing a positioning role; the second guide wheel installed on the top of the second positioning plate plays a guiding role, and the printing medium continues to move after contacting the second guide wheel. The second guide wheel can rotate to reduce the friction of the fixed movement of the printing medium, making its movement more stable.

[0011] Furthermore, the support platform is provided with a cavity, and a heating device is provided inside the cavity.

[0012] A heating device is arranged inside the supporting platform, which can be controlled to heat the supporting plane of the supporting platform to a suitable temperature. The printing medium contacts the supporting plane and transfers heat to the printing medium, so that the ink can be quickly solidified on the printing medium during the printing process, thereby improving the printing quality.

[0013] Furthermore, the support platform is provided with a plurality of adsorption holes and negative pressure outlets, the adsorption holes are evenly distributed on the support plane of the support platform, and the negative pressure outlets are connected with the adsorption holes through the cavities.

[0014] The printing medium is fixed on the support platform by negative pressure adsorption. There are multiple adsorption holes evenly distributed on the support plane. Negative pressure outlets are provided on the side and bottom of the support platform. The negative pressure outlets are connected to the adsorption holes. A negative pressure device is connected to the negative pressure outlets, thereby generating adsorption force through the adsorption holes, so that the printing medium is firmly fixed on the support plane after positioning.

[0015] Furthermore, the support platform is provided with a first sensing device and a second sensing device, the first sensing device and the second sensing device are respectively close to the first edge and the second edge, and are respectively adjacent to the first positioning component and the second positioning component.

[0016] The first sensing device and the second sensing device are respectively installed on the first side and the second side of the supporting platform. When the two sides of the printing medium are positioned by the first positioning component and the second positioning component respectively, the first sensing device and the second sensing device sense the printing medium, the positioning of the printing medium on the supporting plane is completed, and the driving wheel stops rotating. If any sensing device fails to sense the printing medium, it means that the positioning is not completed, and the driving wheel continues to rotate.

[0017] Furthermore, the support plane is provided with a first sensing hole and a second sensing hole, and the first sensing hole and the second sensing hole are respectively located above the first sensing device and the second sensing device.

[0018] A first sensing hole and a second sensing hole are provided on the supporting plane, and the first sensing device and the second sensing device can sense the printing medium through the corresponding first sensing hole and the second sensing hole respectively.

[0019] Furthermore, a supporting plane of the supporting platform is provided with a plurality of through holes, and the through holes correspond one-to-one to the driving wheels.

[0020] The driving wheel and its driving motor are installed in the cavity of the supporting platform. The outer wheel surface of the driving wheel extends out of the supporting plane through the through hole and contacts the printing medium, so that when the driving wheel rotates, the printing medium is driven to move.

[0021] Furthermore, the driving wheel is provided with a circular segment surface, which is parallel to the driving wheel axis. When the circular segment surface rotates to the through hole position and is parallel to the supporting plane of the supporting platform, the circular segment surface is lower than the supporting plane of the supporting platform.

[0022] When the printing medium is positioned, the driving wheel stops rotating. At this time, the circular surface of the driving wheel is located at the through hole, and the circular surface is lower than the supporting plane. The driving wheel does not contact the printing medium, and the printing medium falls on the supporting plane and passes through the adsorption hole, so that the printing medium is adsorbed on the supporting plane and does not move.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] During the printing process, the printing medium is placed on the support platform manually or by a conveying device. Driven by the driving wheel, the printing medium moves toward the first positioning component and the second positioning component. The first positioning component and the second positioning component are higher than the support plane of the support platform. When one side of the printing medium is close to one of the first positioning component and the second positioning component, its moving direction is limited by the positioning component that is attached, and it can only move along the direction of the positioning component. Finally, the other side of the printing medium is attached to the other positioning component. In this process, regardless of whether the printing medium initially placed on the support platform is distorted, it is conveyed by the driving wheel to reach the first positioning component and the second positioning component, and under the limiting effect of the first positioning component and the second positioning component, the two sides of the printing medium are attached to the first positioning component and the second positioning component at the same time, realizing the automatic calibration and positioning of the printing medium on the support platform, without the need for manual intervention to make further positioning adjustments, ensuring the printing quality, and improving the work efficiency.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0036] like Figures 1 to 9 As shown, in a preferred embodiment, a printing automatic calibration heating platform includes a support platform 1, multiple groups of driving wheels 2, a first positioning component 3, and a second positioning component 4. The support platform 1 includes a first side 11 and a second side 12 adjacent to each other. The first positioning component 3 and the second positioning component 4 are respectively close to the first side 11 and the second side 12. The driving wheels 2 are arranged in an array on the support platform 1. The axial direction of the driving wheel 2 has an angle with the first side 11 and the second side 12. The driving wheel 2 can drive the printing medium to move on the support platform 1. In this embodiment, the support platform is rectangular, the first side and the second side are perpendicular to each other, and the axial direction of the driving wheel is perpendicular to the bisector of the angle between the first side and the second side. In other possible embodiments, the shape of the support platform is customized according to actual needs.

[0037] During the printing process, the printing medium is placed on the support platform 1 manually or by a conveying device. Driven by the driving wheel 2, the printing medium moves toward the first positioning component 3 and the second positioning component 4. The first positioning component 3 and the second positioning component 4 are higher than the supporting plane of the support platform 1. When one side of the printing medium is close to one of the first positioning component 3 and the second positioning component 4, its moving direction is limited by the matching positioning component and can only move in the direction of this positioning component. Finally, the other side of the printing medium is matched with the other positioning component. For example, when the printing medium first contacts the second positioning component during the movement, its movement in the first direction is restricted, and the printing medium continues to move in the second direction until it contacts the first positioning component to complete the positioning. In this process, regardless of whether the printing medium initially placed on the supporting platform 1 is distorted, it is transported by the driving wheel to reach the first positioning component 3 and the second positioning component 4, and under the restriction of the first positioning component 3 and the second positioning component 4, both sides of the printing medium are simultaneously fitted with the first positioning component 3 and the second positioning component 4, thereby realizing automatic calibration and positioning of the printing medium on the supporting platform 1, without the need for manual intervention to make further positioning adjustments, thereby ensuring printing quality and improving work efficiency.

[0038] like Figures 1 to 3 As shown, the first positioning assembly 3 includes a first driving member 31, a first positioning plate 32, and a plurality of first guide wheels 33. The first guide wheels 33 are arranged in an array at the top of the first positioning plate 32. The first driving member 31 is connected to the first positioning plate 32 and can drive the first positioning plate 32 to rise and fall. The first positioning assembly 3 not only plays a positioning role, but also plays a guiding role. In the initial state, the first positioning plate 32 rises under the action of the first driving member 31, and its top is higher than the supporting plane of the supporting platform 1, so that the printing medium is blocked when it moves to the first positioning assembly 3, and the first positioning plate 32 plays a positioning role; the first guide wheel 33 installed on the top of the first positioning plate 32 plays a guiding role. After the printing medium contacts with the first guide wheel 33, it continues to move in the first direction. The first guide wheel 33 can rotate to reduce the friction of the fixed movement of the printing medium, making its movement more stable.

[0039] like Figures 1 to 3As shown, the second positioning assembly 4 includes a second driving member 41, a second positioning plate 42, and a plurality of second guide wheels 43. The second guide wheels 43 are arranged in an array at the top of the second positioning plate 42. The second driving member 41 is connected to the second positioning plate 42 and can drive the second positioning plate 42 to rise and fall. The second positioning assembly 4 not only plays a positioning role, but also plays a guiding role. In the initial state, the second positioning plate 42 rises under the action of the second driving member 41, and its top is higher than the supporting plane of the supporting platform 1, so that the printing medium is blocked when it moves to the second positioning assembly 4, and the second positioning plate 42 plays a positioning role; the second guide wheel 43 installed on the top of the second positioning plate 42 plays a guiding role. After the printing medium contacts the second guide wheel 43, it continues to move in the second direction. The second guide wheel 43 can rotate to reduce the friction of the fixed movement of the printing medium, making its movement more stable.

[0040] like Figure 4 As shown, the support platform 1 is provided with a cavity 13, and a heating device 5 is provided inside the cavity 13. The heating device 5 is provided inside the support platform 1, and can be controlled to heat the support plane of the support platform 1 to a suitable temperature. The printing medium contacts the support plane, and the heat is transferred to the printing medium, so that the ink can be quickly solidified on the printing medium during the printing process, thereby improving the printing quality.

[0041] like Figures 1 to 4 As shown, the support platform 1 is provided with a plurality of adsorption holes 14 and a negative pressure outlet 110, the adsorption holes 14 are evenly distributed on the support plane of the support platform 1, the negative pressure outlet 110 is located on the side and bottom of the support platform, and the negative pressure outlet is connected with the adsorption holes 14 through the cavity 13. The printing medium is fixed on the support platform 1 by negative pressure adsorption, and a negative pressure device, such as a turbo fan, is connected to the negative pressure outlet 110, and air is sucked by the turbo fan, thereby generating an adsorption force through the adsorption holes 14, so that the printing medium is firmly fixed on the support plane after positioning.

[0042] like Figures 2 to 5As shown, the support platform 1 is provided with a first sensing device 15 and a second sensing device 16, which are respectively close to the first side 11 and the second side 12, and are respectively adjacent to the first positioning component 3 and the second positioning component 4. The support plane is provided with a first sensing hole 17 and a second sensing hole 18, which are respectively located above the first sensing device 15 and the second sensing device 16. The number of the first sensing device 15 and the second sensing device 16 can be set according to actual needs. When the two sides of the printing medium are positioned by the first positioning component 3 and the second positioning component 4 respectively, the first sensing device 15 and the second sensing device 16 respectively sense the printing medium through the corresponding first sensing hole 17 and the second sensing hole 18, that is, the printing medium is positioned on the support plane, and the driving wheel 2 stops rotating. If any sensing device fails to sense the printing medium, it means that the positioning is not completed, and the driving wheel 2 continues to rotate.

[0043] like Figure 1 , Figure 2 and Figure 5 As shown, the support plane of the support platform 1 is provided with a plurality of through holes 19, and the through holes 19 correspond to the driving wheel 2 one by one. The driving wheel 2 is provided with a circular notch surface 21, and the circular notch surface 21 is parallel to the axis of the driving wheel 2. When the circular notch surface 21 rotates to the position of the through hole 19 and is parallel to the support plane, the circular notch surface 21 is lower than the support plane. The driving wheel 2 and its driving motor are installed in the cavity 13 of the supporting platform 1. The outer wheel surface of the driving wheel 2 extends out of the support plane through the through hole 19 and contacts the printing medium, so that when the driving wheel 2 rotates, the printing medium is driven to move. When the positioning of the printing medium is completed, the driving wheel 2 stops rotating. At this time, the circular notch surface 21 of the driving wheel 2 is located at the through hole 19, and the circular notch surface 21 is lower than the supporting plane. The driving wheel 2 does not contact the printing medium, and the printing medium falls on the supporting plane. From the adsorption hole 14, the printing medium is adsorbed on the supporting plane and does not move.

[0044] like Figures 7 to 9 As shown, the working principle of the automatic calibration and positioning of the printing medium moving on the supporting platform 1 is as follows: Figure 7This is the initial state of the printing medium being placed on the support platform 1. The printing medium is placed on the support platform 1 manually or by a conveying device. The direction of placement is arbitrary and there is no special regulation. The first positioning plate 32 and the second positioning plate 42 are raised, and their end surfaces are higher than the support surface of the support platform 1. Driven by the driving wheel 2, the printing medium moves in the direction of the first positioning component 3 and the second positioning component 4. When one side of the printing medium is close to one of the first positioning component 3 and the second positioning component 4, its moving direction is limited by the fitting positioning component and can only move in the direction of this positioning component. Finally, the other side of the printing medium fits with the other positioning component. At this time, the first sensing device 15 and the second sensing device 16 sense the printing medium respectively, the driving wheel 2 stops rotating, and the adsorption hole 14 adsorbs the printing medium to complete the positioning of the printing medium. The first positioning plate 32 and the second positioning plate 42 are lowered, as shown in FIG. Figure 8 The state diagram of the printing medium after positioning is completed. For example, when the printing medium first contacts the second positioning plate 42 during movement, its movement along the first direction is restricted, and the printing medium continues to move along the second direction until it contacts the first positioning plate 32 and completes positioning. After printing is completed, according to the actual working situation, the first positioning plate 32 and the second positioning plate 42 are controlled to rise. For example, the docking platform of the printing medium is set at a position adjacent to the second edge 12, the first positioning plate 32 is raised, and the second positioning plate 42 remains in the lowered state, the driving wheel 2 rotates, and the printing medium moves out of the support platform 1 along the first direction to the docking platform, as shown in FIG. Fig. 9 A state diagram showing that the printing medium is moved out of the supporting platform 1 after printing is completed.
