Description

Technical Field

[0001] This utility model relates to the technical field of liquid crystal glass substrate production equipment, and specifically to an auxiliary feeding device in a liquid crystal glass substrate feeding system. Background Technology

[0002] In the production process of LCD glass substrates, the batching system needs to accurately feed various powders into the mixing equipment in proportion.

[0003] In existing technology, after the ton bag is opened, the powder passes through a screen into the feeding port. However, due to the poor flowability or tendency of some powder to clump, it easily accumulates on the screen, causing interruptions in the feeding process. At this time, manual unblocking with a long pole is required, which is not only inefficient but also poses a safety hazard of operators coming into contact with the powder. Utility Model Content

The upper support is detachably and fixedly connected between the screen assembly and the inlet flange. The lower support is detachably and fixedly connected between the screen assembly and the outlet flange. A vibration component is provided on the outer periphery of the lower support near the screen assembly.

[0017] (1) The present invention includes an inlet flange and an outlet flange. Multiple support parts are evenly arranged between the inlet flange and the outlet flange. An upper support, a screen assembly, and a lower support are sequentially arranged between the inlet flange and the outlet flange. A vibrating component is arranged on the outer periphery of the lower support near the screen assembly. When the ton bag is unpacked, the powder enters the screen assembly area from the inlet flange. The vibrating component is activated, causing the screen assembly to vibrate at high frequency. Under the action of vibration, the powder passes evenly through the screen assembly and enters the outlet flange. If the powder has poor flowability, the vibration intensity of the screen assembly can be adjusted to ensure continuous feeding. This invention can automatically clear screen blockages, significantly improve feeding efficiency, reduce manual intervention, and ensure operational safety. It is suitable for powder feeding scenarios in LCD glass substrate batching systems.

[0027] Please see Figure 1-3 As shown in the figure, this utility model embodiment provides an auxiliary feeding device in a liquid crystal glass substrate batching system, including an inlet flange 1 and an outlet flange 2 arranged at intervals. In use, the inlet flange 1 is used to connect to the ton bag discharge port, and the outlet flange 2 is used to connect to the liquid crystal glass substrate batching system inlet.

[0028] Please see Figure 1 As shown, in this embodiment, four sets of support parts 3 are evenly arranged between the inlet flange 1 and the outlet flange 2. These four sets of support parts 3 are evenly distributed between the inlet flange 1 and the outlet flange 2, fixing the upper and lower spaced inlet flange 1 and outlet flange 2 into an integral structure. An upper support 4, a screen assembly 5, and a lower support 6 are sequentially arranged between the inlet flange 1 and the outlet flange 2. The upper support 4 is detachably and fixedly connected between the screen assembly 5 and the inlet flange 1, forming an upper conveying channel with an outer circumferential seal between the inlet flange 1 and the screen assembly 5. The lower support 6 is detachably and fixedly connected between the screen assembly 5 and the outlet flange 2, forming a lower conveying channel with an outer circumferential seal between the screen assembly 5 and the outlet flange 2. A vibrating component 7 is arranged on the outer periphery of the lower support 6 near the screen assembly 5. The vibrating component 7 drives the screen assembly 5 to vibrate at high frequency. Under the action of vibration, the powder passes evenly through the screen assembly 5 and enters the discharge port flange 2 from the lower conveying channel.

[0029] Please see Figure 1 As shown, the vibrating component 7 includes a mounting plate 71 and a vibrator 72. In this embodiment, the vibrator 72 is a pneumatic vibrator 72 with an adjustable vibration frequency. The pneumatic vibrator 72 is rigidly connected to the lower support 6 through the mounting plate 71. The vibration energy of the pneumatic vibrator 72 is transmitted to the screen assembly 5, thereby driving the screen assembly 5 to vibrate.

[0030] Further, please refer to Figure 3 As shown, the connection between the upper bracket 4 and the inlet flange 1 is sealed by the first seal 8, and the connection between the lower bracket 6 and the outlet flange 2 is sealed by the second seal 9.

[0031] The first seal 8 ensures a sealed connection between the upper support 4 and the inlet flange 1, and also ensures that powder will not leak from the connection between the upper support 4 and the inlet flange 1 during vibration. The first seal 8 includes a first sealing ring 81 and a first retaining ring 82. The first sealing ring 81 wraps around the connection between the upper support 4 and the inlet flange 1, and the two first retaining rings 82 are wrapped around the outer circumference of the first sealing ring 81 to form a stable sealing connection. Similarly, the first seal 8 ensures a sealed connection between the upper support 4 and the inlet flange 1, and also ensures that powder will not leak from the connection between the upper support 4 and the inlet flange 1 during vibration. The second seal 9 includes a second sealing ring 91 and a second retaining ring 92. The second sealing ring 91 wraps around the connection between the lower support 6 and the outlet flange 2, and the second retaining ring 92 is wrapped around the outer circumference of the second sealing ring 91. The second seal 9 ensures a sealed connection between the lower support 6 and the outlet flange 2, and also ensures that the powder will not leak from the connection between the lower support 6 and the outlet flange 2 during vibration.

[0032] Please see Figure 2 As shown, in this embodiment, the screen assembly 5 includes a screen body 51 and a screen clamp 52. The screen body 51 is fixedly installed inside the screen clamp 52, which is detachable for easy replacement of the screen body 51. During assembly, the bottom edge of the upper bracket 4 is sealed and engaged with the top edge of the screen clamp 52, and the top edge of the lower bracket 6 is sealed and engaged with the bottom edge of the screen clamp 52.

[0033] Please see Figure 3 As shown, in this embodiment, there are four sets of support parts 3, which are evenly distributed between the inlet flange 1 and the outlet flange 2, firmly connecting the inlet flange 1 and the outlet flange 2 together. Each support part 3 includes an upper support plate 31, a lower support plate 32, and a support column 33. The upper support plate 31 is fixedly disposed on the outer periphery of the upper bracket 4, the lower support plate 32 is fixedly disposed on the outer periphery of the lower bracket 6, and the support column 33 is detachably fixed between the upper support plate 31 and the lower support plate 32 by bolts.

[0034] Further, please refer to Figure 3 As shown, in this embodiment, four tension springs 10 are evenly arranged between the inlet flange 1 and the upper support 4, and four tension springs 10 are also evenly arranged between the lower support 6 and the outlet flange 2. The preload of the tension springs 10 is 30-100N. The tension springs 10 further ensure that the inlet flange 1 and the upper support 4 are tightly connected, and that the lower support 6 and the outlet flange 2 are tightly joined together.

[0035] The working principle of this utility model:

[0036] In use, after the ton bag is opened, the powder enters the screen area through the upper conveying channel from the inlet flange 1. The pneumatic vibrator 72 is activated, driving the screen to vibrate at high frequency. Under the action of vibration, the powder passes evenly through the screen and enters the outlet flange 2. If the powder has poor flowability, the vibration intensity can be adjusted by adjusting the air pressure of the pneumatic vibrator 72 to ensure continuous feeding.

[0037] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
