And the printing continuity of the rotary screen non-woven fabric printing machine is influenced due to paint blockage.

Description

Technical Field

[0001] The utility model relates to the technical field of automatic loading and unloading protection of a rotary screen non-woven fabric printing machine, and more specifically, to an automatic loading and unloading device for a rotary screen non-woven fabric printing machine. Background Art

[0002] A rotary screen non-woven fabric printing machine is a device dedicated to printing on non-woven fabric materials, adopting rotary screen printing technology. By printing the coating onto the surface of the non-woven fabric through a circular screen plate, it can achieve high-precision and high-efficiency pattern and text printing, and has the characteristics of wide application range, high production efficiency, and strong environmental protection.

[0003] When the rotary screen non-woven fabric printing machine is in use, it is necessary to transport the coating into its ink tank. In the prior art, when automatically feeding the ink tank, the coating is easily blocked at the feeding port, thereby affecting the continuity of feeding, which results in the printing continuity of the rotary screen non-woven fabric printing machine being affected. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide an automatic loading and unloading device for a rotary screen non-woven fabric printing machine, so as to solve the technical problem that in the prior art, when automatically feeding the ink tank of the rotary screen non-woven fabric printing machine, the coating is easily blocked at the feeding port, thereby affecting the continuity of feeding, which results in the printing continuity of the rotary screen non-woven fabric printing machine being affected.

[0005] To solve the above technical problem, the utility model provides the following technical solution: an automatic loading and unloading device for a rotary screen non-woven fabric printing machine, including a feeding bin for communicating with the internal bin of the rotary screen non-woven fabric printing machine and a transmission mechanism for controlling feeding. The top of the feeding bin is fixedly connected with a feeding pipe communicating with its interior. The top of the feeding bin is fixedly connected with a supporting ring. An activity groove is formed in the top of the supporting ring. A linkage ring is arranged on the top of the supporting ring. A vibrating plate is arranged inside the feeding bin. The bottoms of the vibrating plate and the linkage ring are both fixedly connected with a plurality of corresponding first pull rings. A pull rod is arranged inside the feeding bin. One end of the pull rod sequentially penetrates through the feeding bin and the supporting ring to the activity groove and is slidably connected with the penetrated part. Both ends of the pull rod are fixedly connected with second pull rings, and the second pull rings are respectively hooked together with the first pull rings.

[0006] The transmission mechanism includes a fixed box for fixedly connecting with a circular screen non-woven fabric printing machine. The feeding bin is fixedly connected to the inner wall of the bottom of the fixed box. A motor is fixedly connected to the inner wall of the bottom of the feeding bin. The outer wall of the supporting ring is rotationally connected with a transmission ring. The transmission ring and the main shaft of the motor are synchronously rotationally connected through a belt. A plurality of semi-circular linkage grooves are formed at the bottom of the linkage ring. A pushing block corresponding to the linkage groove is fixedly connected to the top of the transmission ring. The coating enters the bin through the feeding pipe, and then falls on the vibrating plate. The vibrating plate is driven by the transmission mechanism to start vibrating circularly around its center, so that the coating on the vibrating plate starts to uniformly circulate and fall along the gap between the vibrating plate and the inner wall of the feeding bin, and then enters the ink bin of the circular screen non-woven fabric printing machine from the feeding bin, thereby preventing the coating from being blocked during the feeding process of the circular screen non-woven fabric printing machine, which affects the printing continuity of the circular screen non-woven fabric printing machine.

[0007] Preferably, the top of the vibrating plate gradually extends towards the middle to form a circular protrusion, and the circular protrusion formed by the extension of the vibrating plate and the feeding pipe are of the same center. By making the top of the vibrating plate gradually extend towards the middle to form a circular protrusion, when the coating falls on the vibrating plate, the coating will be guided by the circular protrusion, so that the coating uniformly disperses and slides towards the periphery of the vibrating plate, thereby increasing the uniformity of the coating sliding when the vibrating plate vibrates, and further preventing the coating from being blocked.

[0008] Preferably, a rubber ring is fixedly connected to the top of the supporting ring. The bottom of the linkage ring abuts against the top of the rubber ring under its own gravity. The rubber ring is provided to prevent the linkage ring from hitting the supporting ring, resulting in wear of both, and thus the vibrating plate cannot vibrate.

[0009] Preferably, a plurality of rollers are rotationally connected to the top of the pushing block. The outer wall of the rollers abuts against the bottom of the linkage ring. The rollers are provided to prevent the pushing block from being worn and stuck with the bottom of the linkage ring.

[0010] Preferably, a plurality of rubber sleeves are fixedly connected to the top of the vibrating plate. The rubber sleeves cover the first pull ring, the second pull ring and the pull rod, and the other end of the rubber sleeve is fixedly connected to the outer wall of the pull rod. The rubber sleeves are provided to cover the first pull ring, the second pull ring and the pull rod, thereby preventing the coating from affecting the smoothness of the subsequent activities of the first pull ring and the second pull ring when they are hooked.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] 1. The utility model prevents the paint from clogging during the feeding process of the rotary screen non-woven fabric printing machine and affecting the printing continuity of the rotary screen non-woven fabric printing machine by arranging a feeding bin, a feeding pipe, a supporting ring, a movable groove, a linkage ring, a vibrating plate, a first pull ring, a pull rod, a second pull ring and a transmission mechanism. The lithium battery is placed on the supporting plate, and the transmission mechanism drives the vibrating plate to start circular vibration around its center, so that the paint on the vibrating plate starts to uniformly circulate and fall along the gap between the vibrating plate and the inner wall of the feeding bin, and then enters the ink bin of the rotary screen non-woven fabric printing machine from the feeding bin.

[0013] 2. In the utility model, the top of the vibrating plate gradually extends towards the middle to form a circular protrusion. When the paint falls on the vibrating plate, the paint will be guided by the circular protrusion, so that the paint uniformly disperses and slides towards the periphery of the vibrating plate, thereby increasing the uniformity of the paint sliding when the vibrating plate vibrates, and further preventing the paint from clogging.

[0023] As Figures 1 to 7As shown in the figure, the present utility model relates to an automatic loading and unloading device for a rotary screen non-woven fabric printing machine, which includes a loading bin 1 for communicating with the internal bin of the rotary screen non-woven fabric printing machine and a transmission mechanism for controlling the loading. A loading pipe 2 communicating with its interior is fixedly connected to the top of the loading bin 1. A support ring 3 is fixedly connected to the top of the loading bin 1. An activity groove 4 is opened at the top of the support ring 3. A linkage ring 5 is arranged at the top of the support ring 3. A vibrating plate 6 is arranged inside the loading bin 1. A plurality of corresponding first pull rings 7 are fixedly connected to the bottoms of the vibrating plate 6 and the linkage ring 5. A pull rod 8 is arranged inside the loading bin 1. One end of the pull rod 8 sequentially penetrates through the loading bin 1 and the support ring 3 into the activity groove 4 and is slidably connected to the penetrated part. Second pull rings 9 are fixedly connected to both ends of the pull rod 8. The second pull rings 9 are respectively hooked together with the first pull rings 7.

[0024] The transmission mechanism includes a fixed box 10 for fixedly connecting with the rotary screen non-woven fabric printing machine. The loading bin 1 is fixedly connected to the bottom inner wall of the fixed box 10. A motor 11 is fixedly connected to the bottom inner wall of the loading bin 1. A transmission ring 12 is rotatably connected to the outer wall of the support ring 3. The transmission ring 12 and the main shaft of the motor 11 are synchronously rotationally connected by a belt. A plurality of semi-circular linkage grooves 13 are opened at the bottom of the linkage ring 5. A push block 14 corresponding to the linkage groove 13 is fixedly connected to the top of the transmission ring 12. The coating enters the bin through the loading pipe 2, and then falls on the vibrating plate 6. The vibrating plate 6 is driven by the transmission mechanism to start cyclic vibration around its center, so that the coating on the vibrating plate 6 starts to uniformly circulate and fall along the gap between the vibrating plate 6 and the inner wall of the loading bin 1, and then enters the ink bin of the rotary screen non-woven fabric printing machine from the loading bin 1, thereby preventing the coating from clogging during the loading process of the rotary screen non-woven fabric printing machine and affecting the printing continuity of the rotary screen non-woven fabric printing machine.

[0025] Furthermore, the top of the vibrating plate 6 gradually extends towards the middle to form a circular protrusion, and the circular protrusion formed by the extension of the vibrating plate 6 and the loading pipe 2 are of the same center. By making the top of the vibrating plate 6 gradually extend towards its middle to form a circular protrusion, when the coating falls on the vibrating plate 6, the coating will be guided by the circular protrusion, so that the coating uniformly disperses and slides towards the periphery of the vibrating plate 6, thereby increasing the uniformity of the coating sliding when the vibrating plate 6 vibrates, and further preventing the coating from clogging.

[0026] Furthermore, a rubber ring 15 is fixedly connected to the top of the support ring 3. The bottom of the linkage ring 5 abuts against the top of the rubber ring 15 under its own gravity. By providing the rubber ring 15, the linkage ring 5 is prevented from hitting the support ring 3, resulting in wear of both and causing the vibrating plate 6 to be unable to vibrate.

[0027] Furthermore, a plurality of rollers 16 are rotatably connected to the top of the pushing block 14, and the outer wall of the roller 16 abuts against the bottom of the linkage ring 5; the provided rollers 16 prevent the pushing block 14 from wearing and jamming with the bottom of the linkage ring 5.

[0028] Furthermore, a plurality of rubber sleeves 17 are fixedly connected to the top of the material shaking plate 6. The rubber sleeves 17 cover the first pull ring 7, the second pull ring 9 and the pull rod 8, and the other end of the rubber sleeve 17 is fixedly connected to the outer wall of the pull rod 8; the provided rubber sleeves 17 cover the first pull ring 7, the second pull ring 9 and the pull rod 8, thereby preventing the paint from affecting the smoothness of the subsequent movement of the first pull ring 7 and the second pull ring 9 when they are hooked.

[0029] Working principle: This embodiment provides an automatic loading and unloading device for a circular screen non-woven fabric printing machine. When in use, the paint is transported into the feeding pipe 2 by means of existing technical means such as a powder delivery pump. The paint entering the feeding pipe 2 will enter the feeding bin 1 and fall on the material shaking plate 6. When the motor 11 rotates, it will drive the transmission ring 12 to rotate synchronously through the belt. The rotation of the transmission ring 12 drives the pushing block 14 to rotate. The pushing block 14 will sequentially enter the linkage groove 13 and push the linkage ring 5, causing the linkage ring 5 to tilt in sequence. Thus, the linkage ring 5 pulls the material shaking plate 6 to start shaking through the first pull ring 7, the second pull ring 9 and the pull rod 8. The material shaking plate 6 starts to shake and evenly shakes off the paint on its top, causing the paint to slide into the ink bin of the circular screen non-woven fabric printing machine, thereby preventing the paint from clogging during the loading process of the circular screen non-woven fabric printing machine and affecting the printing continuity of the circular screen non-woven fabric printing machine.

[0030] The embodiments disclosed in this utility model are preferred embodiments, but not limited to this. Those of ordinary skill in the art can easily understand the spirit of this utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
