Description

Technical Field

[0001] This utility model belongs to the field of glass microsphere processing and feeding technology, and in particular relates to a glass microsphere glazing and feeding device. Background Technology

[0002] Glazing can provide glass microspheres with an attractive appearance, good protection and optimized surface properties. Due to the fine particle size and high surface energy of glass microspheres, they are very easy to form a stable "bridging" structure during storage and transportation. This arching effect is more significant, especially in the discharge area of ​​inverted conical silos, which often leads to poor material discharge or even interruption, affecting the continuity and uniformity of subsequent glazing processes. Currently, existing technologies typically incorporate built-in stirring devices for forced arch breaking. The rigid contact of the stirring rod can easily cause mechanical damage to the glass microspheres, severely affecting product quality. Furthermore, long-term friction between the stirring rod and the glass microspheres can generate debris that gets mixed into the material, leading to contamination of the glaze surface and a decrease in product qualification rate.

[0003] To address the aforementioned issues, this application proposes a feeding device for glass microsphere coating processing. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for glass microsphere coating and glazing, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a feeding device for glass microsphere coating processing, comprising a screw feeder and a hopper consisting of an upper hopper and a lower hopper, wherein the lower hopper has an inverted conical structure. The device further comprises: Multiple elastic membranes are evenly installed on the side wall of the lower compartment, and the multiple elastic membranes are divided into a first membrane group and a second membrane group. Multiple drive mechanisms are disposed outside the elastic membrane and correspond one to one of the elastic membranes. The drive mechanisms are connected to the motor through a transmission mechanism. The motor drives the drive mechanisms corresponding to the first and second membrane groups to move back and forth alternately through the transmission mechanism.

[0006] Furthermore, the drive mechanism includes a pusher, a push rod, a long connecting rod, and a short connecting rod. The pusher and the push rod are fixedly connected. One end of the long connecting rod is hinged to the push rod, and the other end is rotatably connected to the short connecting rod. One end of the short connecting rod serves as an input end and is connected to the transmission mechanism.

[0007] Furthermore, a fixing ring is fixed to the outer wall of the lower compartment via a fixing rod, and the fixing ring is slidably connected to the guide groove opened on the push rod.

[0008] Furthermore, the transmission mechanism includes a driving gear and a gear ring that mesh with each other, and a gear set in the same number as the drive mechanism. The driving gear is fixedly connected to the output end of the motor. Each gear set includes a driven gear and a driven bevel gear one that are coaxially fixed through a fixed shaft. The driven gear meshes with the gear ring. The input end of the short connecting rod is fixedly connected to a driven bevel gear two through a connecting shaft. The driven bevel gear two meshes with the driven bevel gear one in the same group.

[0009] Furthermore, an outer protective shell is fixed to the outer wall of the lower compartment, and the driving mechanism and transmission mechanism are both located inside the outer protective shell. The gear ring is rotatably connected to the inner wall of the outer protective shell, the motor is fixed to the bottom surface of the outer protective shell, and the inner wall of the outer protective shell is fixed to the L-shaped plate through a fixing block. The two side walls of the fixing block are rotatably connected to the connecting shaft and the fixing shaft, respectively.

[0010] Furthermore, the installation phases of the adjacent driven bevel gears are 180° apart.

[0011] Furthermore, the bottom end of the lower chamber is connected to a discharge pipe, and the bottom end of the discharge pipe is connected to the feed inlet of the screw feeder. A valve is installed on the discharge pipe.

[0012] This utility model has the following beneficial effects: This invention uses an elastic soft membrane to expand and compress materials into the hopper to break up arches, replacing the traditional internal mechanical stirring structure. This reduces direct friction between the material and mechanical parts and lowers the risk of particulate contamination of the material due to wear of the stirring rod. This invention uses a motor to drive the first and second soft membrane groups to expand alternately, forming a wave-like dynamic arch-breaking effect. This causes the elastic soft membrane to periodically lift up, applying dynamic compression and release to the material in the lower chamber. This can continuously destroy the "arch bridge" structure in the inverted cone-shaped chamber, avoiding the problem of material adaptive compaction and arch-breaking failure caused by long-term lifting at a single position.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] 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.

[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Please see Figures 1 to 5 As shown, this utility model is a feeding device for glass microsphere coating and glazing, including a screw feeder 9 and a hopper composed of an upper hopper 1 and a lower hopper 2. The lower hopper 2 has an inverted conical structure and further includes: multiple elastic membranes 4, which are uniformly installed on the side wall of the lower hopper 2 in a circumferential direction. The multiple elastic membranes 4 are divided into a first membrane group and a second membrane group at intervals; multiple driving mechanisms 5 are arranged outside the elastic membranes 4 and correspond to each elastic membrane 4 one by one. The driving mechanism 5 is connected to a motor 6 through a transmission mechanism 7. The motor 6 drives the driving mechanism 5 corresponding to the first membrane group and the second membrane group to move back and forth alternately through the transmission mechanism 7. This embodiment provides a glass microsphere coating and feeding device. An elastic soft membrane 4 is uniformly embedded in the side wall opening of the lower chamber 2. The elastic soft membrane 4 is made of food-grade or industrial-grade silicone rubber. The thickness of the elastic soft membrane 4 can be adaptively selected according to the size of the lower chamber 2 and the pressure of the material, usually in the range of 1mm-5mm, to ensure that it has sufficient strength to break the arch while maintaining sensitive deformation ability. The drive mechanism 5 can push the elastic soft membrane 4 to expand into the lower chamber 2, acting on the material in the hopper to break the arch. All drive mechanisms 5 are connected to the same transmission mechanism 7 and driven by a motor 6. The first soft membrane group and the second soft membrane group are alternately lifted, thereby producing an alternating, wave-like arch-breaking action.

[0019] The drive mechanism 5 includes a pusher 501, a push rod 502, a long connecting rod 503, and a short connecting rod 504. The pusher 501 and the push rod 502 are fixedly connected. One end of the long connecting rod 503 is hinged to the push rod 502, and the other end is rotatably connected to the short connecting rod 504. One end of the short connecting rod 504 is connected to the transmission mechanism 7 as an input end. When the transmission mechanism 7 drives the short connecting rod 504 to move, the long connecting rod 503 swings to drive the push rod 502 to move axially, thereby driving the pusher 501 to push the elastic soft membrane 4 to expand into the lower chamber 2.

[0020] The lower compartment 2 has a fixed ring 8 fixed on its outer wall by a fixed rod 201, and the fixed ring 8 is slidably connected to the guide groove 5021 of the push rod 502. The fixed ring 8 and the guide groove 5021 cooperate to guide the movement of the push rod 502.

[0021] The transmission mechanism 7 includes a driving gear 701 and a gear ring 702 that mesh with each other, and a gear set with the same number as the drive mechanism 5. The driving gear 701 is fixedly connected to the output end of the motor 6. Each gear set includes a driven gear 703 and a driven bevel gear 705 that are coaxially fixed through a fixed shaft 704. The driven gear 703 meshes with the gear ring 702. The input end of the short connecting rod 504 is fixedly connected to a driven bevel gear 706 through a connecting shaft 5041. The driven bevel gear 706 meshes with the driven bevel gear 705 in the same group. The motor 6 drives the driving gear 701 to rotate, which in turn drives the gear ring 702 to rotate. Furthermore, the driven gear 703, the fixed shaft 704, and the driven bevel gear 705 drive the driven bevel gear 706 to rotate, thereby driving the short connecting rod 504 to rotate through the connecting shaft 5041.

[0022] The lower compartment 2 has an outer protective shell 3 fixedly installed on its outer wall. The drive mechanism 5 and the transmission mechanism 7 are both installed inside the outer protective shell 3. The gear ring 702 is rotatably connected to the inner wall of the outer protective shell 3. The motor 6 is fixedly installed on the bottom surface of the outer protective shell 3. The inner wall of the outer protective shell 3 is fixedly connected to the L-shaped plate 302 through the fixing block 301. The two side walls of the fixing block 301 are rotatably connected to the connecting shaft 5041 and the fixing shaft 704, respectively. The outer protective shell 3 can isolate the drive mechanism 5 and the transmission mechanism 7 from the outside world and protect them. It also provides an installation position for the gear ring 702 and the motor 6.

[0023] The adjacent driven bevel gears 706 are installed in phases 180° apart. This phase setting causes the drive mechanisms 5 of the first soft membrane group and the second soft membrane group to operate alternately: when one set of drive mechanisms 5 pushes the elastic soft membrane 4 up, the other set is in the return state, realizing the periodic alternating expansion of the elastic soft membrane, continuously breaking the arch of the material, and avoiding the attenuation of the arch-breaking effect caused by long-term lifting at a single position.

[0024] The lower hopper 2 is connected to a discharge pipe 10 at its bottom end, and the bottom end of the discharge pipe 10 is connected to the inlet of the screw feeder 9. A valve is installed on the discharge pipe 10. When the material enters the screw feeder 9 from the hopper through the discharge pipe 10, it is transported by the screw feeder 9 to the subsequent glazing process. The valve can control the opening and closing of the discharge pipe 10.

[0025] It is understandable that this utility model uses an elastic soft membrane to break up arches, avoiding the problem of material damage or particulate contamination caused by contact between the stirring rod and the material; the alternating expansion of the first and second soft membrane groups forms a dynamic wave-like arch-breaking effect, which can continuously disintegrate the arch bridge structure inside the chamber.

[0026] A specific application of the operation process in this embodiment is as follows: The starting motor 6 drives the driving gear 701 to rotate, which in turn drives all the driven gears 703 to rotate through the gear ring 702. Then, the driven bevel gear 706 is rotated through the fixed shaft 704 and the driven bevel gear 705. The driven bevel gear 706 drives the short connecting rod 504 to rotate. Then, the long connecting rod 503 drives the push rod 502 to move linearly back and forth, so that the push head 501 periodically pushes the elastic soft membrane 4 to expand and squeeze the material in the lower chamber 2 to break the arch. Since the phase difference between the adjacent driven bevel gears 706 is 180 degrees, the push heads 501 corresponding to the two sets of soft membranes alternately move forward and backward, forming a wave-like arch-breaking effect. After the valve of the discharge pipe 10 is opened, the material continuously and evenly falls into the screw feeder 9, completing the stable feeding.
