Description

Technical Field

[0001] This utility model relates to the field of processing technology for substances in a plastic state, and particularly to a quantitative feeding device for preventing bridging of glass tube raw materials. Background Technology

[0002] In the glass tube manufacturing industry, the transportation and supply of raw materials are key links to ensure production continuity and product quality stability. The raw materials used in glass tube production are mostly fine powders or small granular materials such as quartz sand, soda ash, and feldspar powder. During storage and transportation, these materials are prone to problems such as agglomeration and blockage due to differences in their own fluidity, interparticle adhesion, and changes in environmental temperature and humidity. This is what is commonly referred to in the industry as the "bridging" phenomenon.

[0003] Currently, existing glass tube raw material feeding devices typically consist of three main parts: a storage bin, an anti-bridging component, and a quantitative feeding mechanism. The storage bin, as the core component for raw material storage, is usually designed as a cone shape with a wider top and a narrower bottom, which aims to guide the material to the discharge port for easy subsequent conveying.

[0004] The discharge outlets of existing storage silos are mostly single straight cylinders, which rely solely on the natural fall of the material under its own weight. As a result, when the material enters the quantitative feeding mechanism from the storage silo, the flow rate depends entirely on the change in the accumulation height of the material in the silo, exhibiting an unstable state of "fast in the early stage and slow in the later stage". When the material in the silo is sufficient, the material rushes to the discharge outlet rapidly under the action of gravity, forming a "material flow impact". This not only causes severe impact wear on the feed inlet of the quantitative feeding mechanism below, shortening the service life of the equipment, but also causes material accumulation and blockage in the quantitative mechanism due to the excessive instantaneous feeding volume. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a quantitative feeding device for glass tube raw materials to prevent bridging. This device can solve the problem that the discharge port is mostly a single straight cylinder type, which can only rely on the natural fall of the material itself under its own gravity. As a result, when the material enters the quantitative feeding mechanism from the storage bin, the flow rate is completely dependent on the change of the accumulation height of the material in the bin, showing an unstable state of "fast in the early stage and slow in the later stage". When the material in the bin is sufficient, the material rushes to the discharge port quickly under the action of gravity, forming a "material flow impact". This not only causes severe impact wear on the feed port of the quantitative feeding mechanism below, shortening the service life of the equipment, but also causes the material to accumulate and block the quantitative mechanism due to the excessive instantaneous feeding volume.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a glass tube raw material anti-bridging quantitative feeding device, comprising a support frame, a first storage bin, a second storage bin, and two discharge bins, wherein each of the two discharge bins is provided with an inclined baffle assembly; The inclined baffle assembly includes two fixed frames, two motors and two inclined baffles. Inclined baffle grooves are provided on the left and right outer walls of the discharge box. The outer walls of the two inclined baffles are slidably connected to the interior of the corresponding inclined baffle grooves. The two fixed frames are fixedly installed on the front and rear outer walls of the discharge box, and the two motors are fixedly installed on the outer wall of the fixed frame near the discharge box. The outer walls of both fixed frames are provided with fixed block grooves. A fixed block is fixedly installed on the outer wall of the inclined baffle near the fixed frame. A threaded rod is rotatably installed inside the fixed block groove. Three baffles are fixedly installed inside the discharge box. When all three baffles are planar baffles, the three baffles are arranged at an inclination inside the discharge box. Two inclined baffle assemblies are installed inside the discharge box.

[0007] Preferably, the outer wall of the fixing block is slidably connected to the inner wall of the fixing block groove.

[0008] Preferably, the fixing block is threadedly connected to the outer wall of the threaded rod.

[0009] Preferably, the output end of the motor extends rotatably into the interior of the groove of the fixed block and is fixedly connected to one end of the threaded rod.

[0010] Preferably, the two inclined baffles are arranged at an inclination inside the discharge box.

[0011] Preferably, the first storage bin is installed on the upper left side of the support frame, and the second storage bin is installed on the upper right side of the support frame.

[0012] Preferably, the two discharge boxes are fixedly installed at the discharge points of the corresponding first and second storage bins.

[0013] Preferably, a control panel is fixedly installed on the outer wall of the middle support column of the support frame, and the control panel is electrically connected to four motors.

[0014] Preferably, the interiors of the two discharge boxes are connected to the interiors of the corresponding first and second storage bins, respectively.

[0015] Preferably, when all six baffle plates are perforated baffle plates, the six perforated baffle plates are installed inside the two discharge boxes and are all arranged at an angle.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This glass tube raw material anti-bridging quantitative feeding device uses a motor in the inclined baffle assembly to drive the threaded rod in the fixed frame to rotate. By utilizing the "threaded engagement between the threaded rod and the fixed block", the rotational motion is converted into the linear motion of the fixed block. The fixed block is fixedly connected to the inclined baffle, which ultimately drives the inclined baffle to slide along the inclined baffle groove in the discharge box. By adjusting the gap between the two inclined baffles, increasing the gap speeds up the flow rate and decreasing it slows it down, the falling speed of the raw material can be directly controlled. The adjustment process is precisely set through the control panel, realizing real-time and stable control of the feeding flow rate. This avoids deviations in the glass tube raw material ratio due to flow rate fluctuations, ensures product quality consistency, and meets the core production requirement of "quantitative feeding".

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Example 1: Reference Figure 1-4 A basic embodiment of conventional particulate raw materials (planar baffle 9 + ordinary threaded rod 11) Suitable for ordinary glass raw materials (such as quartz sand) with uniform particle size and good flowability. During feeding, the raw material enters the discharge box 14 from the storage silo and is guided layer by layer by three planar baffles 9 to break the bridging trend. The motor 5 drives the ordinary threaded rod 11 to drive the fixed block 10 to slide and adjust the distance between the two inclined baffles 8. The planar baffles guide the raw material to fall in a dispersed manner by tilting the angle. The ordinary threaded rod can realize conventional speed adjustment to meet the quantitative feeding needs of small and medium-sized glass tube production. The structure is simple, easy to maintain, and has a low cost.

[0024] Example 2: Reference Figure 5 Example of anti-bridging for uneven particulate raw materials (porous baffle plate 13 + reinforcing threaded rod) For raw materials with uneven particle size and easy bridging (such as mixed glass slag), the baffle plate is replaced with a porous baffle plate 13. The holes can disperse large particles of raw materials, further reducing the possibility of bridging. The threaded rod 11 is changed to a thicker and stronger type to improve the stability of the inclined baffle during adjustment. When uneven particles of raw materials fall, the porous baffle plate will break up the agglomerated particles. The reinforced threaded rod ensures that the inclined baffle does not shake under the impact of raw materials. The spacing adjustment is precise, effectively avoiding material blockage or speed fluctuation caused by uneven particles.

[0025] Furthermore, when using this device, the raw materials required for glass tube production (such as quartz sand, soda ash, etc.) are respectively loaded into the first storage bin 2 and the second storage bin 3. Under the action of their own gravity, the raw materials flow naturally from the discharge outlet of the storage bin into the corresponding discharge box 14, completing the initial flow of the raw materials. Then, according to the required feeding speed, the control parameters are input through the control panel 6 on the support frame 1. The control panel 6 sends an electrical signal to the corresponding motor 5. After the motor 5 starts, its output end drives the threaded rod 11 in the fixed block slide groove 12 in the fixed frame 4 to rotate. Since the fixed block 10 is threadedly connected to the threaded rod 11, and the fixed block 10 is fixedly connected to the inclined baffle 8, and the inclined baffle 8 is slidably connected to the inclined baffle slide groove 7 of the discharge box 14, the rotational motion of the threaded rod 11 is converted into the linear motion of the fixed block 10 along the fixed block slide groove 12, which in turn drives the inclined baffle 8 to slide along the inclined baffle slide groove 7. Then, the two inclined baffles 8 slide in the discharge box 14. The components are arranged at an angle. By adjusting the gap between them, the falling speed of the raw material can be precisely controlled. When the gap increases, the feeding speed increases, and when the gap decreases, the feeding speed decreases, thus meeting the quantitative feeding requirements. During the falling process of the raw material in the discharge box 14, it will first pass through three inclined baffles 9. If they are planar baffles, they will reduce the impact force of the falling raw material by changing the falling trajectory, preventing the raw material from accumulating and agglomerating at the inclined baffles 8 due to excessive flow velocity, and reducing raw material splashing. If they are porous baffles 13, they can also disperse the raw material through surface holes, further improving the uniformity of the falling raw material and reducing the risk of bridging. Then, during the production process, the operating status of the motor 5 can be monitored and adjusted in real time through the control panel 6, thereby changing the gap of the inclined baffles 8 to adapt to the feeding speed requirements of different raw material characteristics (such as flowability differences) or different production conditions, ensuring the continuity and quantitative accuracy of the entire feeding process.

[0026] The motor 5 in the inclined baffle assembly drives the threaded rod 11 in the fixed frame 4 to rotate. By utilizing the threaded engagement between the threaded rod and the fixed block 10, the rotational motion is converted into the linear motion of the fixed block. The fixed block is fixedly connected to the inclined baffle 8, which ultimately drives the inclined baffle to slide along the inclined baffle groove 7 of the discharge box 14. By adjusting the gap between the two inclined baffles, the flow rate increases when the gap increases and decreases when the gap decreases. The falling speed of the raw material can be directly controlled. The adjustment process is precisely set through the control panel 6, realizing real-time and stable control of the feeding flow rate. This avoids deviations in the raw material ratio of the glass tube due to flow rate fluctuations, ensures product quality consistency, and meets the core production requirement of "quantitative feeding".

[0027] Structural Description: The support frame 1 is the basic load-bearing structure of the entire device, which plays the role of fixing and supporting various functional components. The first storage bin 2 is installed on the upper left side, and the second storage bin 3 is installed on the upper right side. The control panel 6 is fixedly installed on the outer wall of the middle support column. The stable structure of the frame ensures the positional accuracy and operational stability of each component during operation.

[0028] The first storage bin 2 and the second storage bin 3 are raw material storage and initial flow guiding components. They are symmetrically installed on the upper left and upper right sides of the support frame 1, respectively. Each of the two storage bins has a corresponding discharge box 14 fixedly installed at its discharge point. The interior of the storage bin is connected to the interior of the corresponding discharge box 14. This is used to guide the stored glass tube raw materials (such as quartz sand, soda ash, etc.) to the discharge box 14 below. The structural design facilitates the natural fall of the raw materials and reduces the residue of raw materials in the bin.

[0029] Discharge box 14: The discharge box 14 is the core cavity for raw material flow rate control and guidance. There are two discharge boxes 14, which are fixedly installed at the discharge points of the first storage bin 2 and the second storage bin 3, respectively. Each discharge box 14 is equipped with a set of inclined baffle assembly and three baffle plates 9. At the same time, inclined baffle grooves 7 are opened on its left and right outer walls for the inclined baffles 8 to slide. Fixing frames 4 of the inclined baffle assembly are fixedly installed on the front and rear outer walls. By integrating the flow rate control components through the cavity structure, stable conveying of raw materials is achieved. Fixed frame 4: Two fixed frames 4 are fixedly installed on the front and rear outer walls of the discharge box 14 respectively. The outer wall of the fixed frame 4 is provided with a fixed block groove 12. A threaded rod 11 is rotatably installed inside the fixed block groove 12, which serves as the connection and support carrier for the motor 5 and the inclined baffle 8.

[0030] Electric motor 5: Two electric motors 5 are fixedly installed on the outer wall of the fixed frame 4 near the discharge box 14. Their output ends extend into the sliding groove 12 of the fixed block and are fixedly connected to one end of the threaded rod 11 to provide power for the movement of the inclined baffle 8.

[0031] Inclined baffles 8: Two inclined baffles 8 are arranged at an inclination inside the discharge box 14. Their outer walls are slidably connected to the inclined baffle grooves 7 on the left and right outer walls of the discharge box 14, respectively. A fixing block 10 is fixedly installed on the outer wall near the fixing frame 4. The outer wall of the fixing block 10 is slidably connected to the inner wall of the fixing block groove 12 and threadedly connected to the outer wall of the threaded rod 11. The rotation of the threaded rod 11 drives it to slide along the groove, thereby adjusting the gap between the two inclined baffles 8.

[0032] Fixed block 10 and threaded rod 11: Fixed block 10 is the connection medium between inclined baffle 8 and threaded rod 11. Threaded rod 11 converts the rotational motion of motor 5 into linear motion of fixed block 10 through threaded engagement with fixed block 10, thereby driving inclined baffle 8 to move.

[0033] Baffle plate component 9 (planar baffle plate / perforated baffle plate 13): Baffle plate component 9 is an auxiliary flow guiding and stabilizing component. Three are fixedly installed inside each discharge box 14. When it is a planar baffle plate, the three planar baffle plates are all arranged at an angle inside the discharge box 14. By changing the falling path of the raw material, the flow velocity of the raw material is slowed down, avoiding direct impact of the raw material on the inclined baffle 8, and reducing raw material splashing. When it is a perforated baffle plate 13, six perforated baffle plates 13 are installed inside the two discharge boxes 14 respectively and are all arranged at an angle. In addition to the flow stabilizing effect of the planar baffle plate, the holes on its surface can further disperse the raw material, making the raw material fall more evenly, and reducing the probability of raw material agglomeration.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
