[0001] This utility model relates to the field of screen printing technology, and in particular to a feeding device for a screen printing machine suitable for flexible materials. Background Technology

[0002] A screen printing machine is a printing device that uses a screen to transfer ink onto the surface of a substrate. It is commonly used to print patterns, text, and logos on various materials (such as paper, plastic, metal, fabric, and glass). The feeding device of a screen printing machine accurately and stably transports the substrate (such as flexible film, paper, and fabric) to the screen printing position.

[0003] In existing screen printing machine feeding devices, flexible materials are typically placed directly on the upper part of the conveyor belt, and then transported to the printing area by the conveyor belt.

[0004] Although existing screen printing machine feeding devices can complete the conveying of flexible materials, they lack a structure to guide the material during feeding, causing the flexible material to deviate during the conveying process, thus affecting the printing quality. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a feeding device for screen printing machines suitable for flexible materials, aiming to improve the problem in the prior art that the lack of a material guiding structure during feeding causes the flexible material to deviate during the conveying process, thereby affecting the printing quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A feeding device for a screen printing machine suitable for flexible materials, comprising:

[0008] Mounting rack;

[0009] A conveyor belt, installed in the middle of the mounting frame, is used to convey flexible materials;

[0010] Mounting block, which is fixedly connected to the lower right side of the mounting frame;

[0011] Motor 1, wherein motor 1 is disposed at the bottom of the mounting block;

[0012] A gear and two rack plates, wherein the gear is fixedly connected to the output end of the motor, and the two rack plates mesh with the gear;

[0013] Two connecting plates and two guide plates, the two connecting plates being fixedly connected to the outside of the two rack plates, and the two guide plates being fixedly connected to the top of the two connecting plates;

[0014] And a cleaning component for cleaning impurities adhering to the exterior of the conveyor belt.

[0015] Furthermore, the cleaning assembly includes two horizontal plates, which are fixedly connected to the lower left side of the mounting frame. A second motor is provided on the outside of the front horizontal plate, and a rotating shaft is fixedly connected to the output end of the second motor. The rotating shaft is rotatably connected inside the two horizontal plates, and a cleaning roller is fixedly connected to the outside of the rotating shaft.

[0016] Furthermore, a mounting ring is fixedly connected to the lower part of the mounting block, and the motor is fixedly connected inside the mounting ring.

[0017] Furthermore, guide blocks are fixedly connected to the outside of both rack plates, and guide rods are fixedly connected to both sides of the inside of the mounting block. The two guide blocks are slidably connected to the outside of the two guide rods.

[0018] Furthermore, through holes are provided on both sides of the outer side of the mounting block, and the two connecting plates are slidably connected inside the two through holes.

[0019] Furthermore, a screen printing machine body is mounted on the rear side of the mounting bracket.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Referring to Figures 1-3, one embodiment of this utility model provides a feeding device for a screen printing machine suitable for flexible materials, comprising: a mounting frame 1; a conveyor belt 2, installed in the middle of the mounting frame 1, used for conveying flexible materials; a mounting block 3, fixedly connected to the lower right side of the mounting frame 1; a motor 6, disposed at the bottom of the mounting block 3; a gear 8 and two rack plates 9, the gear 8 fixedly connected to the output end of the motor 6, the two rack plates 9 meshing with the gear 8; two connecting plates 12 and two guide plates 13, the two connecting plates 12 fixedly connected to the outside of the two rack plates 9, and the two guide plates 13 fixedly connected to the two connecting plates 12. The top of 2; and a cleaning component, which is used to clean impurities attached to the outside of the conveyor belt 2. A mounting ring 5 is fixedly connected to the lower part of the mounting block 3. The motor 6 is fixedly connected inside the mounting ring 5. The mounting ring 5 is used to fix the motor 6. Guide blocks 10 are fixedly connected to the outside of the two rack plates 9. Guide rods 11 are fixedly connected to both sides inside the mounting block 3. The two guide blocks 10 are slidably connected to the outside of the two guide rods 11. The guide rods 11 are used to facilitate the movement of the guide blocks 10. Through holes 14 are opened on both sides outside the mounting block 3. Two connecting plates 12 are slidably connected inside the two through holes 14. The through holes 14 are used to facilitate the movement of the connecting plates 12.

[0033] Specifically, during the conveying of flexible materials, firstly, the flexible material to be processed needs to be placed stably on the upper right side of the conveyor belt 2. Then, motor 6 is started. After motor 6 starts running, its output end drives the fixedly connected gear 8 to rotate. The rotation of gear 8 causes the meshing rack plates 9 on both sides to move relative to each other. The movement of rack plates 9 further drives the two fixedly connected connecting plates 12 on their outer sides to move relative to each other. As the connecting plates 12 move relative to each other, the two guide plates 13 fixedly installed on their tops also move inward synchronously, gradually approaching the flexible material. When the two guide plates 13 move to contact the left and right sides of the flexible material and form a clamping state, motor 6 is turned off. At this time, the conveyor belt 2 is started, driving the flexible material to move along the conveying path. This achieves the limitation and guidance of the flexible material above the conveyor belt 2, preventing the material from shifting laterally during the conveying process, thereby improving the printing quality of the flexible material in the subsequent printing process.

[0034] Referring to Figures 2-4, the cleaning assembly includes two horizontal plates 16, which are fixedly connected to the lower left side of the mounting frame 1. A second motor 18 is installed on the outside of the front horizontal plate 16, and a rotating shaft 19 is fixedly connected to the output end of the second motor 18. The rotating shaft 19 is rotatably connected to the inside of the two horizontal plates 16. A cleaning roller 20 is fixedly connected to the outside of the rotating shaft 19. The cleaning roller 20 facilitates the cleaning of the conveyor belt 2. The screen printing machine body 4 is installed on the rear side of the mounting frame 1. A fixing ring 17 is fixedly connected to the outside of the front horizontal plate 16. The second motor 18 is fixedly connected to the inside of the fixing ring 17. The fixing ring 17 facilitates the fixing of the second motor 18. A base plate 7 is fixedly connected to the bottom of the mounting frame 1. A dust collection box 15 is installed on the top left side of the base plate 7. The dust collection box 15 facilitates the collection of impurities generated during cleaning.

[0035] Specifically, during the cleaning process of conveyor belt 2, motor 18 is first started. After motor 18 starts running, its output end drives the fixedly connected rotating shaft 19 to start rotating. The rotation of the rotating shaft 19 further drives the cleaning roller 20 fixedly installed on its exterior to rotate synchronously. At the same time, conveyor belt 2 is also in a synchronous running state. Through the contact friction between the cleaning roller 20 and the conveyor belt 2, dust, residues and ink particles and other impurities attached to the surface of the conveyor belt 2 can be removed. During the cleaning process, the impurities generated fall naturally under the action of gravity and eventually fall into the dust collection box 15, preventing impurities from flowing back or re-attaching to the surface of the conveyor belt 2. This can continuously clean the external surface of the conveyor belt 2, ensuring that the conveyor belt 2 remains clean during long-term operation, thereby preventing impurities from being carried to the back or front of the flexible material due to dirt on the surface of the conveyor belt 2, which would affect the appearance quality of the product.

[0036] Working principle: When conveying flexible materials, firstly, the flexible material is placed on the upper right side of the conveyor belt 2. Then, the motor 6 is started. The motor 6 drives the gear 8 fixed at the output end to rotate. The rotation of the gear 8 causes the meshing rack plates 9 on both sides to move relative to each other. The relative movement of the two rack plates 9 causes the two externally fixed connecting plates 12 to move relative to each other. The relative movement of the two connecting plates 12 causes the two top fixed guide plates 13 to move relative to each other. When the two guide plates 13 come into contact with the outer sides of the flexible material, the motor 6 is turned off, and then the conveyor belt 2 is started again to convey the flexible material. This facilitates the guidance of the flexible material conveyed on the upper part of the conveyor belt 2 during the conveying process, avoids deviation during the conveying process, and thus improves the printing quality.

[0037] When cleaning conveyor belt 2, firstly, motor 218 is started. Motor 218 drives the rotating shaft 19 fixed at the output end to rotate. The rotating shaft 19 drives the externally fixed cleaning roller 20 to rotate. At the same time, as conveyor belt 2 rotates, cleaning roller 20 also rotates. The rotation of cleaning roller 20 can continuously clean the outside of conveyor belt 2. The impurities generated during cleaning fall into the dust collection box 15 under the action of gravity. This makes it easy to clean the outside of conveyor belt 2 when conveying flexible materials, and avoids the dirt on the surface of conveyor belt 2 being directly transferred to the back or front of the material, thereby improving the quality of the product.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
