Description

Technical Field

[0001] This utility model relates to the field of screen printing machine technology, and specifically to a transition conveying device for screen printing. Background Technology

[0002] Screen printing refers to the process of using a screen as a printing plate base and creating a screen printing plate with images and text through a photosensitive plate-making method. Screen printing consists of five main elements: screen printing plate, squeegee, ink, printing platform, and substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen printing plate in the image areas, while ink cannot pass through the mesh openings in the non-image areas. During printing, ink is poured into one end of the screen printing plate, and a squeegee applies a certain pressure to the ink areas on the screen printing plate while moving at a constant speed towards the other end of the screen printing plate. As the squeegee moves, the ink is squeezed from the mesh openings of the image areas onto the printing material (substrate).

[0003] To increase the speed of screen printing, two screen printing machines are typically installed side-by-side, with a dryer downstream of each machine. Two more screen printing machines are then installed downstream of the dryer, and so on. The number of screen printing machines and dryers is determined based on actual production needs. However, because the width of the dryer is smaller than the width of the two screen printing machines, their inlet and outlet ports cannot be aligned. Printed materials exiting either the screen printing machine or the dryer's outlet must be manually moved to the dryer's or screen printing machine's inlet, resulting in low efficiency. Therefore, a transition conveyor device is urgently needed to facilitate the transfer between the screen printing machine and the dryer. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a transition conveying device for screen printing. This transition conveying device can realize automatic conveying between upstream and downstream processing devices, thereby improving production efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A transition conveying device for screen printing includes a frame, a conveying module mounted on the frame, and a positioning and handling module; wherein,

[0007] The conveying module is used to convey the printed materials along the X-axis direction;

[0008] The aligning and positioning transport module is used to align and position the printed materials on the transport module in the Y-axis direction and to transport the printed materials on the transport module along the Y-axis direction. The aligning and positioning transport module includes an aligning transport mechanism and a Y-axis drive mechanism for driving the aligning transport mechanism to move along the Y-axis direction. The aligning transport mechanism includes an aligning plate for aligning the printed materials, an adsorption component for adsorbing the printed materials, and a lifting drive component for driving the adsorption component to move up and down.

[0009] The working principle of the above-mentioned transition conveying device is as follows:

[0010] Printed materials processed by the upstream processing unit exit the upstream processing unit's outlet and enter the conveying module. The conveying module transports the printed materials forward a certain distance along the X-axis, then stops. The Y-axis drive mechanism drives the straightening and transporting mechanism to move along the Y-axis. The straightening plate gradually approaches the printed materials and straightens and positions them, ensuring their correct orientation. Next, the lifting drive component drives the adsorption component to rise or fall (i.e., move along the Z-axis; the direction of movement varies depending on the adsorption component's position). After the adsorption component contacts the printed materials, it adsorbs them and then moves the printed materials along the conveying module. After rising a certain distance, the printed material leaves the conveying module. The Y-axis drive mechanism drives the aligning and transporting mechanism to move along the Y-axis, moving the printed material until it aligns with the inlet of the downstream processing device. The Y-axis drive mechanism then stops driving, and the lifting drive component drives the adsorption component to descend, causing the printed material to fall onto the conveying module. The lifting drive component then drives the adsorption component to descend or rise, causing the adsorption component to leave the printed material. The Y-axis drive mechanism drives the aligning and transporting mechanism to move along the Y-axis, causing the aligning plate to move away from the printed material. The conveying module then drives the printed material forward along the X-axis, transporting it to the inlet of the downstream processing device.

[0011] In a preferred embodiment of this invention, the transition conveying device is disposed between the upstream processing device and the downstream processing device. The conveying directions of the upstream and downstream processing devices are the same as the conveying direction of the conveying module, and the discharge port of the upstream processing device does not correspond to the inlet of the downstream processing device. In the above structure, printed materials entering the conveying module from the discharge port of the upstream processing device are positioned by the alignment and positioning transport module and then transported to the position corresponding to the inlet of the downstream processing device, thus achieving transition conveying.

[0012] In a preferred embodiment of this utility model, the aligning and positioning transport module further includes a mounting base slidably disposed on the frame and a mounting plate disposed on the mounting base; the aligning plate is disposed on one side of the mounting plate, and the lifting drive assembly is disposed on the other side of the mounting plate; the mounting base is connected to the Y-axis drive mechanism. By setting the above structure, the installation of the aligning plate and the lifting drive assembly is facilitated. The Y-axis drive mechanism drives the mounting base to move, which in turn drives the mounting plate to move, thereby achieving synchronous movement of the aligning plate, the lifting drive assembly, and the adsorption assembly along the Y-axis direction.

[0013] Preferably, the conveying module includes multiple conveying rollers arranged along the X-axis on the frame. The rotation of the conveying rollers allows the printed material to be conveyed along the X-axis.

[0014] Preferably, the straightening plate is a rake-tooth straightening plate, which includes a plate body and a plurality of straightening teeth disposed on the plate body; the straightening teeth are located between two adjacent conveyor rollers, and the plurality of straightening teeth are arranged along the X-axis direction, with a clearance groove between two adjacent straightening teeth for avoiding the conveyor rollers. By setting the above structure, the straightening plate will not interfere with the conveyor rollers during the straightening process, while also ensuring a more compact structure; during straightening, the straightening teeth straighten one side of the printed material, so that the printed material is aligned and positioned.

[0015] Preferably, the adsorption assembly includes a connecting plate and a plurality of suction cups disposed on the connecting plate, the plurality of suction cups being arranged along the X-axis direction; the connecting plate is connected to the lifting drive assembly. By providing multiple suction cups, the stability of the suction cup adsorption can be improved.

[0016] Preferably, the Y-axis drive mechanism, connecting plate, and plate body are all located below the conveying module. This arrangement makes the entire transition conveying device very compact. After the printed material is aligned and positioned, the lifting drive assembly drives the suction assembly to rise. The suction assembly contacts the bottom of the printed material, adsorbs it, and then lifts the material a short distance, moving it away from the conveying module. When the printed material aligns with the inlet of the downstream processing device, the lifting drive assembly drives the suction assembly to descend, causing the printed material to fall onto the conveying module. The suction cup stops adsorbing, and the lifting drive assembly drives the suction assembly to descend again, causing the suction assembly to leave the printed material.

[0017] Preferably, the aligning teeth are arranged in a one-to-one correspondence with the suction cups. This is to ensure that the suction cups are positioned between the two conveying rollers, allowing them to avoid the conveying rollers during lifting and lowering movements.

[0018] Preferably, the lifting drive component is a lifting cylinder, one end of which is connected to the connecting plate, and the other end of which is connected to the mounting plate. The lifting and lowering movement of the adsorption component is achieved through the extension and retraction of the lifting cylinder, resulting in a simpler structure and reduced costs.

[0019] Preferably, the Y-axis drive mechanism includes a Y-axis drive motor, a driving pulley, a driven pulley, and a transmission belt; the main shaft of the Y-axis drive motor is connected to the driving pulley, the transmission belt is connected between the driving pulley and the driven pulley, and the transmission belt is fixedly connected to the mounting base. The Y-axis drive motor drives the transmission belt, which in turn drives the mounting base, thus realizing the movement of the aligning and conveying mechanism.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] In this utility model, the transition conveying device, after the printed material from the outlet of the upstream processing device enters the conveying module, since the outlet of the upstream processing device does not correspond to the inlet of the downstream processing device, drives the straightening and conveying mechanism to move along the Y-axis direction through the Y-axis drive mechanism. The straightening plate gradually approaches the printed material and straightens and positions it, making the printed material upright. The lifting drive component drives the adsorption component to move up and down, and in conjunction with the Y-axis drive mechanism, it can transport the straightened printed material to the position corresponding to the inlet of the downstream processing device. The printed material can then be conveyed to the inlet of the downstream processing device through the conveying module. This realizes automatic conveying between the upstream and downstream processing devices, improving production efficiency. During the screen printing process, the transition conveying device can provide transitional conveying between the screen printing machine and the dryer. Attached Figure Description

[0033] To enable those skilled in the art to fully understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0034] Example 1

[0035] See Figures 1-2 This embodiment discloses a transition conveying device for screen printing, including a frame 1, a conveying module 2 disposed on the frame 1, and a positioning and transporting module.

[0036] See Figures 1-3 The conveying module 2 is used to convey the printed material 3 along the X-axis direction; the conveying module 2 includes multiple conveying rollers 2-1, which are arranged along the X-axis direction on the frame 1. By rotating the conveying rollers 2-1, the printed material 3 can be conveyed along the X-axis direction.

[0037] See Figures 1-8 The patting and positioning transport module is used to pat and position the printed matter 3 on the transport module 2 in the Y-axis direction and to transport the printed matter 3 on the transport module 2 along the Y-axis direction. The patting and positioning transport module includes a patting and transport mechanism 4 and a Y-axis drive mechanism 5 for driving the patting and transport mechanism 4 to move along the Y-axis direction. The X-axis direction is parallel to the Y-axis direction. The patting and transport mechanism 4 includes a patting plate 4-1 for patting the printed matter 3, an adsorption component 4-2 for adsorbing the printed matter 3, and a lifting drive component 4-3 for driving the adsorption component 4-2 to move up and down.

[0038] See Figures 1-4 The transition conveying device is located between the upstream and downstream processing devices. The conveying directions of the upstream and downstream processing devices are the same as those of the conveying module 2. However, the outlet of the upstream processing device does not correspond to the inlet of the downstream processing device. In this structure, the printed material 3, which exits from the outlet of the upstream processing device and enters the conveying module 2, is positioned by the alignment and positioning transport module and then transported to the position corresponding to the inlet of the downstream processing device, thus achieving transition conveying.

[0039] See Figures 1-4 The upstream processing device is a screen printing machine 6, with two screen printing machines 6 arranged side by side. The downstream processing device is a dryer 7. A transition conveying device can realize the transition conveying of the screen printing machine 6 to the dryer 7.

[0040] See Figures 1-8 The positioning and transport module further includes a mounting base 4-4 slidably mounted on the frame 1 and a mounting plate 4-5 mounted on the mounting base 4-4; the positioning plate 4-1 is located on one side of the mounting plate 4-5, and the lifting drive assembly 4-3 is located on the other side of the mounting plate 4-5; the mounting base 4-4 is connected to the Y-axis drive mechanism 5. By setting the above structure, the mounting plate 4-1 and the lifting drive assembly 4-3 are easily installed. The Y-axis drive mechanism 5 drives the mounting base 4-4 to move, which in turn drives the mounting plate 4-5 to move, thereby achieving synchronous movement of the positioning plate 4-1, the lifting drive assembly 4-3, and the adsorption assembly 4-2 along the Y-axis direction.

[0041] See Figures 7-9 The straightening plate 4-1 is a rake-shaped straightening plate, comprising a plate body 4-11 and multiple straightening teeth 4-12 disposed on the plate body 4-11. The straightening teeth 4-12 are located between two adjacent conveyor rollers 2-1, and the top height of the straightening teeth 4-12 is greater than the top height of the conveyor rollers 2-1, that is, the straightening teeth 4-12 extend upwards out of the conveyor module 2. The multiple straightening teeth 4-12 are arranged along the X-axis direction, and a clearance groove 4-13 is provided between two adjacent straightening teeth 4-12 to avoid the conveyor rollers 2-1. The plate body 4-11 is mounted on the mounting plate 4-5. By setting the above structure, the straightening plate 4-1 will not interfere with the conveyor rollers 2-1 during the straightening process, and at the same time, the structure is more compact. During straightening, the straightening teeth 4-12 straighten one side of the printed product 3, so that the printed product 3 is aligned and positioned.

[0042] See Figures 7-9 The number of teeth 4-12 is 7, and the number of clearance grooves 4-13 is 6.

[0043] See Figures 5-8 The adsorption component 4-2 includes a connecting plate 4-21 and a plurality of suction cups 4-22 disposed on the connecting plate 4-21, the plurality of suction cups 4-22 being arranged along the X-axis direction; the connecting plate 4-21 is connected to the lifting drive component 4-3. By providing a plurality of suction cups 4-22, the adsorption stability of the suction cups 4-22 can be improved.

[0044] See Figures 2-8 The Y-axis drive mechanism 5, connecting plate 4-21, and plate body 4-11 are all located below the conveying module 2. Similarly, the mounting base 4-4 and mounting plate 4-5 are also located below the conveying module 2. This arrangement makes the entire transition conveying device very compact. After the printed product 3 is aligned and positioned, the lifting drive assembly 4-3 drives the suction assembly 4-2 to rise. After the suction assembly 4-2 contacts the bottom of the printed product 3, it suctions the printed product 3 and then lifts the printed product 3 a certain distance, moving it away from the conveying module 2. When the printed product 3 aligns with the feed inlet of the downstream processing device, the lifting drive assembly 4-3 drives the suction assembly 4-2 to descend, and the printed product 3 falls onto the conveying module 2. The suction cup 4-22 stops suction, and the lifting drive assembly 4-3 drives the suction assembly 4-2 to descend, causing the suction assembly 4-2 to leave the printed product 3. By suctioning and lifting, the stability of the printed product 3 during transport can be improved.

[0045] See Figures 2-8 The 4-12 teeth are arranged in a one-to-one correspondence with the suction cups 4-22. The purpose is to position the suction cups 4-22 between the two conveying rollers 2-1, so that the suction cups 4-22 can avoid the conveying rollers 2-1 when they are moving up and down.

[0046] See Figures 2-8 The lifting drive component 4-3 is a lifting cylinder. One end of the lifting cylinder is connected to the connecting plate 4-21, and the other end is connected to the mounting plate 4-5. The lifting and lowering movement of the adsorption component 4-2 is achieved through the extension and retraction movement of the lifting cylinder, resulting in a simpler structure and cost savings.

[0047] See Figures 2-8 The Y-axis drive mechanism 5 includes a Y-axis drive motor 5-1, a driving pulley 5-2, a driven pulley 5-3, and a transmission belt 5-4. The main shaft of the Y-axis drive motor 5-1 is connected to the driving pulley 5-2, and the transmission belt 5-4 is connected between the driving pulley 5-2 and the driven pulley 5-3. The transmission belt 5-4 is fixedly connected to the mounting base 4-4. The Y-axis drive motor 5-1 drives the transmission belt 5-4 to move, which in turn drives the mounting base 4-4 to move, thus realizing the movement of the straightening and conveying mechanism 4.

[0048] See Figures 2-8 A guide assembly is provided between the frame 1 and the mounting base 4-4. The guide assembly includes a guide rod 8 disposed on the frame 1 and a slider 9 disposed on the mounting base 4-4. The slider 9 cooperates with the guide rod 8.

[0049] See Figures 1-8 The conveying module 2 is provided with a guide plate 10 near the feed inlet of the downstream processing device. The guide plate 10 is used to guide the printed matter 3 into the feed inlet of the downstream processing device. The side of the conveying module 2 (the side near the suction cup 4-22) is provided with a positioning baffle. By using the aligning plate 4-1 and the positioning baffle, the two opposite sides of the printed matter 3 can be positioned along the Y axis to improve the positioning accuracy.

[0050] See Figures 1-8 A rod 12 is mounted on the frame 1, and the rod 12 is arranged parallel to the Y-axis. Multiple photoelectric sensors 13 are provided on the rod 12. A baffle 14 is provided on the mounting base 4-4. A switch control signal can be generated through the baffle 14 and the photoelectric sensor 13, thereby realizing the precise movement of the straightening and conveying mechanism 4.

[0051] See Figures 1-8 The working principle of the above-mentioned transition conveying device is as follows:

[0052] The printed material 3, processed by the upstream processing device, exits from the discharge port of the upstream processing device and enters the conveying module 2. The conveying module 2 conveys the printed material 3 forward along the X-axis for a certain distance, then stops conveying. The Y-axis drive mechanism 5 drives the straightening and conveying mechanism 4 to move along the Y-axis (in this embodiment, the straightening and conveying mechanism 4 is driven to move along the Y-axis away from the feed port of the downstream processing device). The straightening plate 4-1 gradually approaches the printed material 3 and straightens and positions the printed material 3, making its posture upright. Then, the lifting drive component 4-3 drives the adsorption component 4-2 to rise (i.e., move along the Z-axis). After the adsorption component 4-2 contacts the printed material 3, it adsorbs the printed material 3 and then drives the printed material 3 to rise for a certain distance. The printed material 3 leaves the conveying module 2, and the Y-axis drive mechanism 5 drives the straightening and conveying mechanism 4 to move in the opposite direction along the Y-axis (driving...). The clapping and conveying mechanism 4 moves along the Y-axis direction and towards the feed inlet of the downstream processing device, driving the printed product 3 to move until the printed product 3 corresponds to the feed inlet of the downstream processing device. The Y-axis drive mechanism 5 stops driving, and then the lifting drive component 4-3 drives the adsorption component 4-2 to descend, and the printed product 3 falls onto the conveying module 2. After adsorption stops, the lifting drive component 4-3 drives the adsorption component 4-2 to descend, so that the adsorption component 4-2 leaves the printed product 3. The Y-axis drive mechanism 5 can continue to drive the clapping and conveying mechanism 4 to move in the opposite direction along the Y-axis direction, so that the clapping plate 4-1 moves away from the printed product 3. Alternatively, the Y-axis drive mechanism 5 can not work, so the clapping plate 4-1 does not need to move away from the printed product 3 and can still play a conveying and guiding role. The conveying module 2 drives the printed product 3 to be conveyed forward along the X-axis direction, and conveys the printed product 3 to the feed inlet of the downstream processing device. The printed product 3 enters the downstream processing device for processing.

[0053] Example 2

[0054] join Figure 10 In this embodiment, the other structures are the same as in embodiment 1, except that the upstream processing device is a dryer 7, and the downstream processing device is a screen printing machine 6, with the two screen printing machines 6 arranged side by side. The transition conveying device can realize the transition conveying from the dryer 7 to the screen printing machine 6.

[0055] Example 3

[0056] join Figure 11In this embodiment, the other structures are the same as in Embodiment 1, except that the Y-axis drive mechanism 5, the connecting plate 4-21, and the plate body 4-11 are all located above the conveying module 2. Similarly, the mounting base 4-4 and the mounting plate 4-5 are also located above the conveying module 2. After the printed product 3 is aligned and positioned, the lifting drive component 4-3 drives the adsorption component 4-2 to descend. After the adsorption component 4-2 contacts the top of the printed product 3, it adsorbs the printed product 3 and then drives the printed product 3 to rise a certain distance, so that the printed product 3 is away from the conveying module 2. When the printed product 3 corresponds to the feed port of the downstream processing device, the lifting drive component 4-3 drives the adsorption component 4-2 to descend, and the printed product 3 falls onto the conveying module 2. The suction cup 4-22 stops adsorbing, and the lifting drive component 4-3 drives the adsorption component 4-2 to rise, so that the adsorption component 4-2 leaves the printed product 3.

[0057] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
