Description

Technical Field

[0001] This application belongs to the field of substrate glass, and specifically relates to a device for storing and using small pieces of glass substrate. Background Technology

[0002] In the glass manufacturing industry, the accurate proportioning and efficient addition of minor additives (such as clarifying agents, colorants, fluxes, and other functional additives) have a significant impact on product quality. Currently, the industry commonly uses manual methods for weighing, temporarily storing, and adding these minor additives. Specifically, operators typically transport the ton bags of minor raw materials to the feeding area, untie the ropes at the bottom of the bags on-site, allowing the raw materials to fall directly into an open hopper or temporary container, and then add them to the mixing system manually by shoveling or pouring.

[0003] However, the above-mentioned traditional operation methods have many problems: First, small materials are exposed to the air for a long time during temporary storage and feeding, which makes them very susceptible to moisture or impurities, causing raw material contamination and affecting the quality of glass melting; Second, manual unpacking, handling, and feeding are labor-intensive and inefficient, and the frequent exposure to dust poses a potential threat to the health of operators.

[0004] Although some improvement solutions have attempted to introduce enclosed silos or simple supports, they generally suffer from problems such as unreasonable structural design, poor sealing, inconvenience in movement, and lack of safety protection, and cannot fundamentally solve the core needs of pollution prevention, efficient material preparation, and personnel safety protection in the process of storing small materials. Summary of the Invention

[0005] The technical problem to be solved by this application is to provide a device for storing and using small parts of glass substrates, which significantly improves the cleanliness and dispensing accuracy of small parts storage, and also greatly reduces the intensity of manual intervention and the risk of dust exposure.

[0006] This application provides a device for storing and using small pieces of glass substrate, including: Main frame; A hopper is fixedly installed on the main frame, the hopper including a hopper body and a hopper cover movably installed on the top of the hopper body; A ton bag support installed on the main frame and located above the hopper; The discharge valve assembly is located at the bottom of the hopper. The discharge valve assembly includes a discharge cylinder connected to the bottom of the hopper, a guide structure located inside the discharge cylinder, and an insert plate inserted into the discharge cylinder and slidingly engaged with the guide structure. The insert plate is used to control the flow cross-sectional size of the discharge cylinder.

[0007] Optionally, the small material storage and use device further includes a linear adjustment component for moving the insert plate.

[0008] Optionally, the linear adjustment assembly includes a crossbeam fixed to the main frame, a mounting base disposed at one end of the insert plate, a lead screw connected to the mounting base, a nut fixed to the crossbeam and screwed to the lead screw, and a drive component for rotating the lead screw.

[0009] Optionally, the driving component is a handwheel.

[0010] Optionally, the linear adjustment assembly further includes a pointer rotatably connected to the handwheel and a scale fixedly mounted on the crossbeam and cooperating with the pointer. The tip of the pointer rests on the top of the scale under the action of gravity. The distance the slide plate moves is displayed by the cooperation between the pointer and the scale, so as to accurately determine the opening size of the discharge valve assembly.

[0011] Optionally, the discharge cylinder has a rectangular cylindrical structure.

[0012] Optionally, the bottom of the silo is funnel-shaped.

[0013] Optionally, the ton bag support includes two symmetrically distributed support frames and two crossbars connecting the two support frames, with the area enclosed by the two support frames and the two crossbars located directly above the feeding port of the silo.

[0014] Optionally, the guiding structure includes guide rails fixedly disposed on both sides of the inner wall of the discharge cylinder, and the two sides of the insert plate are slidably embedded in the guide rails to restrict the reciprocating movement of the insert plate in the horizontal direction and prevent it from deviating or getting stuck.

[0015] Optionally, the bottom of the main frame is equipped with casters with brakes to facilitate the flexible movement and positioning of the entire device within the workshop.

[0016] The beneficial effects of this application are that by integrating a ton bag support, a hopper, and a controllable discharge valve assembly, a closed-loop operation is achieved for the entire process of unpacking and discharging small materials from the ton bag. After the ton bag is placed on the support, the material can be directly unloaded into the sealed hopper below, effectively isolating air and impurities and preventing moisture and contamination. The movable design of the hopper cover facilitates material addition and maintenance, while the discharge valve assembly, with its insert plate and guide structure, allows for precise adjustment of the discharge cross-section, achieving quantitative and controllable discharging. This device not only significantly improves the cleanliness and batching accuracy of small material storage but also greatly reduces the intensity of manual intervention and the risk of dust exposure. It combines high efficiency, safety, and practicality, solving the core problems of pollution, inefficiency, and health hazards associated with traditional manual discharging methods.

Detailed Implementation

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] like Figure 1 and Figure 2 As shown, this application provides a small-material storage and usage device for glass substrates, including: a main frame 100, a hopper 200 fixedly disposed on the main frame 100, a ton bag support 300 disposed on the main frame 100 and located above the hopper 200, and a discharge valve assembly 400 disposed at the bottom of the hopper 200; wherein, the hopper 200 includes a hopper body 210 and a hopper cover 220 movably disposed on the top of the hopper body 210; the discharge valve assembly 400 includes a discharge cylinder 410 connected to the bottom of the hopper 200, a guide structure disposed in the discharge cylinder 410, and an insert plate 420 inserted into the discharge cylinder 410 and slidably engaged with the guide structure, the insert plate 420 being used to control the flow cross-sectional size of the discharge cylinder 410.

[0021] Compared with existing technologies, the glass substrate small-material storage and usage device provided in this application, by integrating a ton bag support 300, a hopper 200, and a controllable discharge valve assembly 400, achieves a closed-loop operation of the entire process from unpacking the ton bag to dispensing the small materials. After the ton bag is placed on the support, the material can be directly unloaded into the sealed hopper 200 below, effectively isolating air and impurities and preventing moisture and contamination. The movable design of the hopper cover 220 facilitates material addition and maintenance, while the discharge valve assembly 400, with its insert plate 420 and guide structure, can precisely adjust the discharge cross-section to achieve quantitative and controllable dispensing. This device not only significantly improves the cleanliness and batching accuracy of small-material storage but also greatly reduces the intensity of manual intervention and the risk of dust exposure. It combines high efficiency, safety, and practicality, solving the core problems of pollution, inefficiency, and health hazards associated with traditional manual dispensing methods.

[0022] In one possible implementation, the small material storage and use device also includes a linear adjustment component 500 for moving the insert plate 420.

[0023] Specifically, the small material storage and usage device is equipped with a linear adjustment component 500, which drives the insert plate 420 to move smoothly along the axial direction of the discharge cylinder 410, thereby precisely controlling the opening of the discharge port. The linear adjustment component 500 can be in the form of an electric push rod, a cylinder, or a screw nut 540 mechanism, with one end fixed to the main frame 100 or the outer wall of the discharge cylinder 410, and the other end connected to the insert plate 420. Through manual operation or automatic control system commands, the linear adjustment component 500 drives the insert plate 420 to make linear reciprocating motion under the constraint of the guide structure, realizing continuous or graded adjustment of the flow section.

[0024] In one possible implementation, the linear adjustment assembly 500 includes a crossbeam 510 fixed to the main frame 100, a mounting base 520 disposed at one end of the insert plate 420, a lead screw 530 connected to the mounting base 520, a nut 540 fixed to the crossbeam 510 and screwed to the lead screw 530, and a drive member 550 for rotating the lead screw 530.

[0025] Specifically, the linear adjustment assembly 500 achieves precise linear drive of the insert plate 420 through a transmission mechanism of lead screw 530 and nut 540: the crossbeam 510 is fixed to the main frame 100, providing stable support for the entire adjustment assembly; one end of the insert plate 420 is connected to the mounting base 520, the lead screw 530 is fixed to the mounting base 520, and the nut 540 that mates with the lead screw 530 is fixed to the crossbeam 510; when the driving component 550 (such as a handwheel, motor, or geared motor) drives the lead screw 530 to rotate, since the nut 540 is fixed in position, the lead screw 530 moves axially under the side effect of the thread, thereby pushing or pulling the mounting base 520 and the insert plate 420 connected to it to slide within the discharge cylinder 410. This structure efficiently converts rotary motion into linear displacement, and has the advantages of smooth transmission, accurate positioning, and good self-locking. It can be manually fine-tuned to adapt to different batching requirements, or connected to an automatic control system to achieve remote or programmed adjustment, significantly improving the flexibility, accuracy, and operational safety of discharge control.

[0026] In one possible implementation, the drive element 550 is a handwheel.

[0027] Specifically, the drive unit 550 uses a handwheel, which the operator can manually rotate to drive the lead screw 530. Since the nut 540 is fixed to the crossbeam 510, the lead screw 530 generates a linear displacement along the axial direction during rotation, which in turn drives the connected insert plate 420 to slide smoothly within the discharge cylinder 410, thereby adjusting the opening of the discharge port. This design is simple in structure, low in cost, and easy to maintain. Furthermore, the handwheel operation is intuitive and controllable, allowing on-site workers to make precise adjustments according to actual material requirements.

[0028] In one possible implementation, such as Figure 2 As shown, the linear adjustment assembly 500 also includes a pointer 560 rotatably connected to the handwheel and a scale 570 fixedly mounted on the crossbeam 510 and cooperating with the pointer 560. The tip of the pointer 560 rests on the top of the scale 570 under the action of gravity. The distance the slide plate 420 moves is displayed by the cooperation between the pointer 560 and the scale 570, so as to accurately determine the opening size of the discharge valve assembly 400.

[0029] Specifically, when the operator turns the handwheel to adjust the position of the insert plate 420, the handwheel drives the lead screw 530 to rotate, and the pointer 560 moves synchronously with it, its tip sliding along the surface of the scale 570, indicating in real time the displacement of the insert plate 420 relative to its initial position. Since the displacement of the insert plate 420 corresponds to the opening of the discharge port, the operator can intuitively and accurately determine the opening size of the discharge valve assembly 400 by reading the scale value corresponding to the pointer 560, thereby achieving precise control over the amount of small materials added. This design requires no additional power supply or sensors, has a reliable structure, provides clear readings, and significantly improves the operational accuracy and repeatability of manual adjustment.

[0030] In one possible implementation, the discharge cylinder 410 adopts a rectangular cylinder structure with a rectangular cross-section that matches the planar shape of the insert plate 420. This facilitates the smooth sliding of the insert plate 420 along the inner wall of the cylinder, effectively blocking or opening the discharge channel. Compared to circular or other irregular cross-sections, the rectangular structure is easier to manufacture and ensures the fitting accuracy between the insert plate 420 and the inner wall of the cylinder, reducing the risk of material leakage. Simultaneously, the flow area of ​​the rectangular discharge port is linearly related to the displacement of the insert plate 420, allowing for intuitive and accurate control of the discharge volume through the movement distance of the insert plate 420.

[0031] In one possible implementation, the bottom of the silo 210 is designed as a funnel-shaped structure, that is, a cone or sloping wall that gradually narrows from top to bottom. This facilitates the smooth and concentrated flow of small materials to the discharge port under the action of gravity, effectively avoiding problems such as material accumulation, bridging or blockage at the bottom of the silo.

[0032] In one possible implementation, the ton bag support 300 consists of two symmetrically arranged support frames 310 and two crossbars 320 connecting their tops, forming a stable frame structure. The enclosed area is located directly above the feeding port of the hopper 210. This layout ensures that after the ton bag is hoisted and placed, its discharge port is precisely aligned with the feeding port of the hopper 210, enabling vertical and centralized unloading of materials into the hopper 200, preventing spillage or displacement. Simultaneously, the symmetrical support structure enhances the overall load-bearing capacity and stability, safely supporting the weight of a fully loaded ton bag and facilitating forklift or lifting equipment operation.

[0033] In one possible implementation, the guide structure includes guide rails (not shown in the figure) fixedly disposed on both sides of the inner wall of the discharge cylinder 410, and the two sides of the insert plate 420 are slidably embedded in the guide rails to limit the reciprocating movement of the insert plate 420 in the horizontal direction and prevent it from deviating or getting stuck.

[0034] Specifically, the guide structure effectively constrains the slide plate 420 to move only horizontally, preventing unexpected displacements such as vertical warping, lateral shifting, or rotation during adjustment. This avoids problems such as jamming, poor sealing, or increased operating resistance caused by the slide plate 420's misalignment. The cooperation between the guide rail and the slide plate 420 not only improves the smoothness of movement and repeatability of positioning, but also enhances the reliability and durability of the discharge valve assembly 400 during long-term use.

[0035] In one possible implementation, the bottom of the main frame 100 is equipped with casters 110 with brakes, which facilitates the flexible movement and positioning of the entire device within the workshop.

[0036] Specifically, operators can easily move the device to different workstations or near the mixing system according to production needs, significantly improving the flexibility and site adaptability of the equipment. When the device reaches the designated position, the braking mechanism of the universal wheel 110 can effectively prevent it from sliding or displacing due to vibration or external force during feeding, storage or discharging, ensuring operational safety and feeding accuracy.
