Description

Technical Field

[0001] The utility model relates to the technical field of tableware manufacturing, in particular to a tableware polishing device. Background Art

[0002] In the field of food packaging, especially for tableware that comes into direct contact with food, in order to increase the aesthetics of the tableware, protect the tableware, improve the quality of the tableware and ensure food safety, non-toxic, odorless, non-volatile glazing oils are usually selected, such as water-based glazing oils, to glaze the tableware to ensure food safety. Tableware glazing usually refers to the use of glazing technology or the application of a protective film.

[0003] In the prior art, when polishing tableware, it is first necessary to apply the corresponding polish oil or polish glue on the surface of the tableware, and then polish it by wiping or other means. After polishing, it is dried or naturally dried so that the polish oil or polish glue can be permanently attached to the surface of the tableware; in the polishing process, in addition to the aforementioned wiping means, there is also a means of external force adsorption to achieve the polishing of excess polish oil or polish glue on the surface of the tableware. When the above means are used to polish the tableware, polishing equipment is usually used.

[0004] The glazing equipment in the prior art usually includes a glazing unit or a glazing glue unit, a polishing unit and a drying unit. The glazing unit or the glazing glue unit is used to glaze the tableware with glazing oil or glazing glue, and then the glazing oil or glazing glue attached to the surface of the tableware is polished by the polishing unit. Finally, the glazing oil or glazing glue on the surface of the tableware is dried by the drying unit, thereby completing the entire glazing work of the tableware. Among them, during polishing, for tableware using glazing oil or glazing glue with strong adsorption and relatively regular tableware, the existing glazing equipment is usually provided with a grinding disc for polishing. For tableware using glazing oil or glazing glue with average adsorption and irregular tableware, the existing glazing equipment is usually provided with an adsorption device to adsorb excess glazing oil or glazing glue on the surface of the tableware to achieve a polishing effect. With this structure, when there is a lot of excess varnish or gloss glue on the surface of the tableware, or the ambient temperature is too high or too low causing the varnish or gloss glue to condense, the adsorption device may not be able to absorb the excess varnish or gloss glue or it may take a long time to absorb it, resulting in not only low polishing efficiency but also poor polishing effect, which will in turn affect the polishing efficiency and polishing effect of the entire polishing equipment. Utility Model Content

[0005] The utility model aims to solve the above problems existing in the prior art and provides a tableware polishing device which has the advantages of high polishing efficiency and good polishing effect.

[0006] Specifically, the tableware glazing equipment includes a rack, a conveying device, a gluing device, a polishing device, and a drying device. The conveying device, the gluing device, the polishing device, and the drying device cooperate with each other to form a continuous and automated production process. When the tableware is glazed, the tableware can enter from the material entrance, pass through each station in turn, and finally be output from the material exit. The entire process does not require manual intervention, which greatly improves production efficiency.

[0007] Furthermore, the rack extends along the direction in which the tableware is conveyed, and a gluing station, a polishing station and a drying station are sequentially arranged on the rack along the direction in which the tableware is conveyed; a conveying device is extendedly arranged at the top of the rack along the direction in which the tableware is conveyed, extending from the material inlet of the glazing device to the material outlet, and is used to convey the tableware from the material inlet to the material outlet via the gluing station, the polishing station and the drying station in sequence; each station (gluing station, polishing station, drying station) is sequentially arranged on the rack along the direction in which the tableware is conveyed, so that the tableware can be smoothly transferred from one station to the next during the conveying process, thereby reducing waiting time and transportation costs.

[0008] Furthermore, the gluing device is located below the gluing station and the conveying device, so that the gluing device can accurately gluing the tableware conveyed to the gluing station. The polishing device is located below the polishing station and the conveying device, and the polishing device includes a primary polishing component and a secondary polishing component sequentially arranged along the tableware conveying direction. The primary polishing component includes a blowing component arranged on the frame, and the blowing component blows air from top to bottom to the tableware passing through; the secondary polishing component includes an air suction component arranged below the tableware, and the air suction component sucks air from below to the tableware passing through; the polishing device adopts a combination of a primary polishing component and a secondary polishing component. The primary polishing component blows air to the tableware through the blowing component to remove excess glue or impurities; the secondary polishing component sucks air to the tableware through the air suction component to further refine the polishing effect. This combination not only improves the polishing efficiency, but also ensures the polishing quality; and the primary polishing component and the secondary polishing component of the polishing device perform fine polishing on the tableware by blowing and sucking. The primary polishing removes excess glue, and the secondary polishing further refines the surface gloss, making the surface of the tableware smoother and brighter.

[0009] Furthermore, the drying device is located below the drying station and the conveying device, and the drying device includes a drying chamber for drying the tableware conveyed through the drying chamber. The drying device dries the tableware conveyed through the drying chamber. The high temperature environment in the drying chamber can quickly evaporate the moisture and residual glue on the surface of the tableware, so that the tableware reaches a dry state in a short time. This not only improves production efficiency, but also ensures the durability of the glazing effect.

[0010] Therefore, the tableware polishing device provided by the utility model not only has the advantage of high polishing efficiency, but also has the advantage of good polishing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] For tableware, oiling can increase the gloss and smoothness of the tableware surface, making it look more beautiful and elegant. Tableware with high gloss can reflect the shape and color of objects, enhance the visual effect, and thus improve the overall dining experience. In addition, through oiling, a protective film will be formed on the surface of the tableware, which can enhance the durability of the tableware.

[0030] In this regard, when manufacturing tableware, for tableware with regular shapes and smooth surfaces, manufacturers choose varnish with strong adsorption for varnishing. During the polishing stage, grinding discs are usually used for polishing. Due to the strong adsorption of varnish and the regular shape of tableware, the grinding disc can effectively distribute the varnish evenly on the surface of the tableware and achieve the polishing effect through mechanical friction.

[0031] However, for tableware with irregular shapes and complex surfaces, such as disposable knives, forks, and spoons, manufacturers often choose varnish with average adsorption for varnishing. During the polishing stage, an adsorption device is usually used to remove excess varnish. However, due to the average adsorption of varnish and the complex shape of tableware, the adsorption device may not be able to effectively absorb all the excess varnish on the surface of the tableware. In particular, when the varnish is applied excessively, the ambient temperature is too high, causing the varnish to dry and condense quickly, or the ambient temperature is too low, causing the fluidity of the varnish to decrease, the working efficiency of the adsorption device will drop significantly. This will not only lead to low varnishing efficiency, but also affect the final varnishing effect because the excess varnish cannot be completely removed.

[0032] Therefore, it is extremely important to provide a tableware glazing device with high glazing efficiency and good glazing effect in the field of tableware manufacturing.

[0033] To this end, the utility model provides a tableware polishing device, which can greatly improve the polishing efficiency and polishing effect of the tableware polishing device.

[0034] In order to more clearly introduce the tableware polishing device provided by the utility model, the following is a description in conjunction with the accompanying drawings:

[0035] See also Figure 1 and Figure 2 The tableware polishing device provided by the utility model includes a frame 100, a conveying device 200, a gluing device 300, a polishing device 400, and a drying device 500. The gluing device 300, the polishing device 400, and the drying device 500 are sequentially arranged along the tableware conveying direction 101, so that the conveying device 200, the gluing device 300, the polishing device 400, and the drying device 500 cooperate with each other to form a continuous and automated production process. When the tableware is polished, the tableware can enter from the material inlet 1011, pass through each station in turn, and finally be output from the material outlet 1012. The whole process does not require manual intervention, which greatly improves the production efficiency.

[0036] When in use, the tableware can be transported from the material inlet 1011 to the glazing device, and then automatically transported to each station by the conveying device 200. The conveying device 200 ensures the continuous movement of the tableware in the equipment, avoiding the tediousness and errors of manual handling. When the tableware is transported to the gluing station 110, the gluing device 300 will automatically gluing the tableware. The tableware after gluing is further transported to the polishing station 120. The polishing device 400 polishes the surface of the tableware to remove minor flaws and unevenness on the surface to make it smoother. Finally, the tableware is transported to the drying station 130. The drying device 500 can heat the tableware by hot air or infrared rays, so that the moisture and glue on the surface evaporate quickly to achieve the purpose of drying. The drying process ensures that the tableware can be quickly restored to the use state after glazing, avoiding quality problems caused by residual moisture. After all the above processes, the tableware is finally transported out from the material outlet 1012. At this time, the tableware has completed the glazing process, the surface gloss will be significantly improved, and the quality is also effectively guaranteed.

[0037] The tableware polishing equipment provided by the utility model can realize automated production by continuously conveying tableware between various workstations through the conveying device 200, which not only greatly improves production efficiency, but also reduces the possibility of manual intervention and errors. The coordinated cooperation of the gluing device 300, the polishing device 400 and the drying device 500 ensures a high-quality polishing effect on the surface of the tableware, and the uniform application of glue, the smoothness of polishing and the dryness of drying can all be effectively controlled.

[0038] The structures and arrangements of the frame 100, the conveying device 200, the gluing device 300, the polishing device 400, and the drying device 500 are described in detail below:

[0039] About Rack 100:

[0040] See also Figure 1 and Figure 2 In the tableware polishing equipment, the frame 100 is the supporting structure of the entire equipment, bearing the weight of various components and tableware, ensuring that the equipment will not collapse or deform due to excessive weight during operation. When in use, the frame 100 provides installation locations for various components such as the conveying device 200, the gluing device 300, the polishing device 400 and the drying device 500. The various parts of the conveying device 200, the gluing device 300 and the polishing device 400 can be fixed to the frame 100 by bolts, nuts and other connectors, thereby forming a complete production line.

[0041] The structure of the rack 100 is not limited. For example, it can be made of a solid metal material (such as steel or aluminum alloy). Specifically, it can include a base, that is, the bottom of the rack 100, which can be a large-area planar structure for supporting the weight of the entire device and ensuring the stability of the device. A column is extended upward from the base to support various components such as the conveying device 200, the gluing device 300, the polishing device 400 and the drying device 500. The number and position of the columns are determined according to the scale and layout of the equipment. The rack 100 can also be provided with a crossbeam connecting the columns, which can further enhance the stability and rigidity of the rack 100. The crossbeam can also be used as a support for installing other components (such as a control panel, a motor, etc.), and the rack 100 can also be provided with a connection structure such as bolts, nuts, and welding points. The connection structure can be used to connect the various parts of the rack 100 together to form an integral structure.

[0042] In one embodiment, the frame 100 is configured to extend along the tableware conveying direction 101, and a gluing station 110, a polishing station 120 and a drying station 130 are sequentially arranged on the frame 100 along the tableware conveying direction 101. The frame 100 includes a bottom bracket 140, a plurality of supporting legs 150 erected on the bottom, and a top bracket 160 fixedly arranged on the top ends of the plurality of supporting legs 150.

[0043] Specifically, the bottom bracket 140 is the base of the rack 100 and can be a solid plane or frame structure to support the weight of the entire device to prevent the glazing device from shaking or collapsing during operation. The bottom bracket 140 can also be provided with adjustment feet or shock-absorbing pads, which can be fine-tuned according to the unevenness of the ground to ensure the smooth operation of the device.

[0044] The support legs 150 are configured as vertical structures extending upward from the bottom bracket 140, connecting the bottom bracket 140 with the top bracket 160. The number and position of the support legs 150 are not the only requirements, and can be determined according to the scale and layout of the equipment to ensure that the various workstations on the top bracket 160 can be evenly distributed and remain stable. Transverse supports or reinforcing ribs can also be provided between the support legs 150 to enhance the stability of the entire rack 100.

[0045] The top bracket 160 is the upper structure of the frame 100, and is fixedly arranged at the top of the plurality of supporting legs 150 to ensure that the gluing station 110, the polishing station 120 and the drying station 130 can be arranged in sequence according to a predetermined order and position. The top bracket 160 can also be provided with accessories such as mounting plates, guide rails or slide rails to install and fix the equipment of each station.

[0046] In this embodiment, the bottom bracket 140, supporting legs 150 and top bracket 160 of the frame 100 can together form a stable, sturdy and easy-to-maintain structure, providing a reliable support and installation basis for the tableware polishing equipment, and the extension design of the frame 100 along the tableware conveying direction 101 ensures that the equipment can continuously process tableware according to a predetermined process, which is conducive to improving production efficiency and product quality.

[0047] Regarding the conveying device 200:

[0048] See also Figures 1 to 3 The conveying device 200 is extendedly arranged on the top of the frame 100 along the tableware conveying direction 101, extending from the material inlet 1011 of the glazing equipment to the material outlet 1012, and is used to convey the tableware from the material inlet 1011 to the material outlet 1012 through the gluing station 110, the polishing station 120 and the drying station 130 in sequence. Each station (gluing station 110, polishing station 120, drying station 130) is arranged in sequence on the frame 100 along the tableware conveying direction 101. During the operation of the equipment, the conveying device 200 enables the tableware to be smoothly transferred from one workstation to the next during the conveying process, thereby continuously and stably conveying the tableware from the material inlet 1011 to each workstation (gluing station 110, polishing station 120, drying station 130), and finally outputting it from the material outlet 1012, thereby achieving the smooth and orderly transfer of tableware between the various workstations. By cooperating with the gluing device 300, the polishing device 400 and the drying device 500, the automation of the tableware polishing process is further realized without the need for manual intervention, thereby greatly improving production efficiency.

[0049] The conveying device 200 can be in various forms such as chains, belts, or other types of conveying. For example:

[0050] Belt conveyor: The belt conveyor can drive the tableware forward through the friction on the belt. It is suitable for horizontal or inclined transportation of block, granular and whole materials.

[0051] Chain conveyor: Chain conveyor can fix and transport tableware through hooks or clamping devices on the chain. It consists of chains and sprockets and is suitable for conveying heavy materials or materials that require precise positioning.

[0052] In one embodiment, taking a belt conveyor as an example, the belt conveyor may include a conveyor belt, a driving device, a bracket and a supporting mechanism, and a tensioning device. The conveyor belt is the core part of the belt conveyor, and may be composed of a flexible belt (such as a rubber belt, a plastic belt, a canvas belt, etc.) or a chain belt (such as a wire mesh belt, a hinged plate belt, etc.). Under the action of the driving device, the conveyor belt can move continuously to transport tableware from one end to the other. The driving device is the power source of the conveyor belt, and may be composed of a motor, a reducer, and a driving wheel. The motor provides power, the reducer reduces the speed and increases the torque, and the driving wheel drives the conveyor belt to move through friction with the conveyor belt or chain transmission. The bracket is the supporting structure of the belt conveyor, and may be welded by channel steel, angle steel, and steel plate and fixed to the frame 100 of the glazing device. The supporting mechanism is used to support the conveyor belt and the materials it carries to ensure smooth operation of the conveyor belt.

[0053] It should be understood that for flexible belt conveyors, rollers can be used to support the conveyor belt; since it has a certain elongation, it will stretch under the action of tension. The tensioning device can be used to compensate for this elongation, ensure close contact between the conveyor belt and the drive wheel, and avoid slipping. The tensioning device can be a tensioning wheel.

[0054] In another embodiment, the conveying device 200 adopts a conveying chain 210, and the conveying device 200 includes the conveying chain 210. The conveying chain 210 is the main part of the conveying device 200, and is composed of multiple chain links (for example, 100, 200, etc.). The chain links are connected by connecting parts to form a continuous closed loop. The conveying chain 210 extends along the top of the frame 100, starting from the material inlet 1011 and extending to the material outlet 1012. Specifically, the conveying chain 210 can be arranged along the tableware surrounding the top bracket 160. This design makes full use of the vertical space, making the structure of the entire equipment more compact and occupying a smaller area.

[0055] Furthermore, a plurality of hanging interfaces are arranged at intervals along the conveying direction on the conveying chain 210 , and a hanging component 220 is engaged with each hanging interface of the conveying chain 210 located below the top bracket 160 , and tableware can be hung on the corresponding hanging component 220 . When in use, at the material inlet 1011, the tableware that needs to be polished is hung one by one on the hanging member 220 of the conveying device 200. As the conveying chain 210 moves, the hanging interface on the chain moves accordingly, driving the hanging member 220 connected thereto to move together. The hanging member 220 and the tableware hung thereon are conveyed to each workstation. At the gluing station 110, the gluing device 300 evenly glues the tableware; at the polishing station 120, the first-level polishing component 410 of the polishing device 400 removes excess glue or impurities by blowing, and the second-level polishing component 420 further refines the polishing effect by suction; at the drying station 130, the drying device 500 dries the tableware so that it reaches a dry state in a short time. After being processed by all workstations, the tableware is conveyed to the material outlet 1012, and then each tableware is unloaded one by one.

[0056] Furthermore, each hanging member 220 extends in a direction perpendicular to the conveying direction, for example, it may extend downward in a vertical direction, and a plurality of tableware may be suspended side by side at the lower end of each hanging member 220. This design allows a plurality of tableware to be suspended side by side, and a large number of tableware may be efficiently processed in a single cycle, thereby improving work efficiency and greatly reducing manual handling and waiting time. In addition, since the conveying device 200 can stably convey the tableware to each workstation, and the transfer between each workstation is smooth, it can be ensured that each tableware can be uniformly glued, polished and dried, thereby ensuring product quality.

[0057] The structure of the suspension member 220 is not limited, for example, it can be various structures such as electric hooks, electromagnetic buckles, and clamps. Taking the clamp as an example, the clamp can be a pneumatic clamp or an electric clamp. At the material inlet 1011, the pneumatic clamp or the electric clamp can be automatically controlled to open, and clamp the tableware and clamp it to achieve clamping the tableware. At the material outlet 1012, the pneumatic clamp or the electric clamp can be automatically controlled to open to release the clamped tableware. The specific control of the pneumatic clamp or the electric clamp is not the only requirement of the utility model. For example, the relay can control the motor to drive the clamp to open and close automatically.

[0058] There is no limit to the number of suspension components 220 , and it can be any number such as 50 or 100.

[0059] The hanging interface may be a structure with an inner wall clamping platform configured to match the hanging component 220. When the hanging component 220 is connected to the hanging interface, one end of the hanging component 220 can be clamped in the hanging interface.

[0060] About Polishing Device 400:

[0061] See also Figure 4 and Figure 6 The polishing device 400 is used to polish the surface of the tableware after the tableware is glued, to remove excess glue, impurities or minor flaws that may be generated during the gluing process, and to further refine the glossiness of the tableware surface to make it smoother and brighter. The polishing device 400 plays a connecting role in the tableware polishing equipment of the utility model. It is located between the gluing station 110 and the drying station 130, ensuring that the tableware can be smoothly polished after gluing, and enter the drying station 130 for drying after polishing. The existence of the polishing device 400 not only improves the overall quality and aesthetics of the tableware, but also makes the entire production process smoother and more efficient.

[0062] In the present invention, the polishing device 400 is located below the polishing station 120 and the conveying device 200, and the polishing device 400 includes a primary polishing assembly 410 and a secondary polishing assembly 420 sequentially arranged along the tableware conveying direction 101. This combination not only improves the polishing efficiency, but also ensures the polishing quality; and the primary polishing assembly 410 and the secondary polishing assembly 420 of the polishing device 400 perform fine polishing on the tableware by blowing and sucking. The primary polishing removes excess glue, and the secondary polishing further refines the surface gloss, making the tableware surface smoother and brighter.

[0063] The specific structure of the polishing device 400 can be designed according to actual needs and equipment scale. For example, the blowing component 411 of the primary polishing assembly 410 can be in the form of a high-pressure air gun or an air nozzle, etc., and the polishing effect can be controlled by adjusting the size and direction of the air flow. The suction component 421 of the secondary polishing assembly 420 can be in the form of a vacuum pump or a negative pressure generator, etc., which can absorb tiny particles and impurities on the surface of the tableware by generating negative pressure.

[0064] About the first-level polishing assembly 410:

[0065] See also Figure 4 The primary polishing assembly 410 includes a blowing component 411 disposed on the frame 100. The blowing component 411 blows air from top to bottom on the tableware passing through, and uses the power of the airflow to remove excess glue, impurities, etc. on the surface of the tableware. The main purpose of the primary polishing assembly 410 is to perform preliminary cleaning and finishing on the surface of the tableware to prepare for the subsequent secondary polishing.

[0066] The blowing component 411 may include a plurality of blowing members 4111 arranged in pairs, for example, 8, 10, or 12 blowing members 4111 are arranged in parallel with each other, and the blowing ports of each blowing member 4111 are arranged in a direction perpendicular to the conveying direction, for example, along the width direction of the frame 100, and each pair of blowing members 4111 is tilted downward relative to the vertical direction and opposite to each other, and this tilted design helps to direct the airflow more concentratedly to the tableware, while increasing the contact area and contact time between the airflow and the surface of the tableware, thereby improving the polishing effect. In addition, this allows a primary polishing area 412 to be formed between two blowing members 4111 in each pair of blowing members 4111; when the tableware passes through the primary polishing area 412, the blowing ports of each blowing member 4111 can blow air from top to bottom to the passing tableware.

[0067] When the blowing port of each blowing member 4111 blows air from top to bottom at the passing tableware, the blowing member 4111 can be arranged above the tableware to blow air from top to bottom at the passing tableware; or the blowing member 4111 can be arranged to move from top to bottom while blowing air. Such dynamic movement helps to ensure that the airflow can more evenly cover the entire surface of the tableware, thereby eliminating uneven polishing or missed areas that may occur in static polishing, and can more effectively remove glue residues, impurities and tiny scratches on the surface of the tableware, thereby enhancing the uniformity and quality of polishing, thereby improving the surface quality and gloss after polishing.

[0068] The structure of the blowing component 4111 is not limited, for example, it can be a blowing nozzle, the air inlet of the blowing nozzle is connected to an external air pump, and the air outlet of the blowing nozzle serves as the blowing port of the blowing component 4111 to blow air to the passing tableware from top to bottom.

[0069] In this regard, in the present invention, the primary polishing assembly 410 further includes a first lifting component 413 disposed on the frame 100, and the blowing component 411 is fixedly connected to the lifting end of the first lifting component 413. When the tableware enters the primary polishing area 412, the first lifting component 413 drives the blowing component 4111 to move from top to bottom, and the blowing port of each blowing component 4111 blows air from top to bottom to the passing tableware. During the operation of the equipment, when the tableware enters the primary polishing area 412, the first lifting component 413 starts to work, driving the blowing component 411 to move from top to bottom. Specifically, before the tableware enters the primary polishing area 412, the first lifting component 413 is in an initial state, and the blowing component 411 is not driven to rise. This can avoid collision and interference between the tableware and the blowing component 411 when the tableware is transported to the primary polishing area 412. After the tableware enters the primary polishing area 412, the tableware will be stopped and transported, and stay above the primary polishing area 412. At this time, the first lifting component 413 drives the blowing component 411 to rise. When it rises until the tableware is in the primary polishing area 412, the blowing component 411 starts to blow, and the first lifting component 413 drives the blowing component 411 to rise and then gradually descend, so that the blowing port of each blowing component 4111 blows the passing tableware from top to bottom.

[0070] The first lifting component 413 can adopt various structures to realize its function, for example:

[0071] The first lifting component 413 can be an electric lifting platform 4133. The electric lifting platform 4133 drives a transmission mechanism such as a lead screw or a chain through a motor to achieve the lifting action of the lifting platform.

[0072] The first lifting component 413 may adopt a pneumatic lifting device, which uses air pressure difference to drive the lifting platform to move up and down.

[0073] The first lifting component 413 may adopt a hydraulic lifting system, which presses hydraulic oil into the oil cylinder through a hydraulic pump to drive the lifting platform to rise; and returns oil to the oil cylinder to achieve the platform lowering.

[0074] The first lifting component 413 may also adopt a mechanical lifting mechanism: such as a spiral lift, a scissor-type lifting platform 4133, etc., to achieve the lifting function through mechanical transmission.

[0075] During use, when the tableware enters the primary polishing area 412, the first lifting component 413 receives a start signal. According to the preset polishing parameters (such as tableware height, polishing force, etc.), the first lifting component 413 adjusts the height of the blowing component 411, and the blowing component 411 moves from top to bottom to a position at an appropriate distance from the surface of the tableware under the drive of the lifting component. The blowing port of each blowing component 4111 begins to release airflow to polish the tableware. After polishing is completed, the first lifting component 413 drives the blowing component 411 to return to the initial position and wait for the next round of polishing operation.

[0076] Specifically, the first lifting component 413 may include a first driving member 4131 , a first screw assembly 4132 , and a lifting platform 4133 disposed on the first screw assembly 4132 as a lifting end.

[0077] The first driving member 4131 is a key component for providing power, and is fixedly arranged on the frame 100 and located on one side of the blowing member 411. The first driving member 4131 can be a motor, a hydraulic motor, etc., and its driving shaft is connected to the screw in the first screw assembly 4132 for driving the rotation of the screw.

[0078] The first screw rod assembly 4132 includes a screw rod rotatably erected at the bottom of the frame 100, and a nut sleeved on the screw rod. The driving shaft of the first driving member 4131 is transmission-connected to the screw rod in the first screw rod assembly 4132. The threaded cooperation between the screw rod and the nut enables the nut to move in the vertical direction along the screw rod when the first driving member 4131 drives the screw rod to rotate.

[0079] The end of the lifting platform 4133 is fixedly connected to the nut of the first screw assembly 4132, so when the nut moves, the lifting platform 4133 will also rise and fall accordingly, and a blowing space is formed in the middle of the lifting platform 4133, and the first-level polishing area 412 is located in the blowing space. The blowing space can be used to accommodate the blowing component 411 and tableware to ensure that the polishing operation can proceed smoothly.

[0080] The blowing components 4111 are arranged in pairs and fixed on the lifting platform 4133, wherein the two blowing components 4111 of each pair of blowing components 4111 are arranged opposite to each other in the horizontal direction, and multiple pairs of blowing components 4111 are arranged in sequence along the vertical direction. When the lifting platform 4133 is lifted and lowered along with the nut, each pair of blowing components 4111 will also move with the lifting platform 4133.

[0081] During use, when the tableware enters the primary polishing area 412, the first driving member 4131 is started, the driving shaft rotates and drives the screw in the first screw assembly 4132 to rotate, and the rotation of the screw causes the nut sleeved thereon to move along the screw in the vertical direction, thereby driving the lifting platform 4133 to rise and fall, and the lifting platform 4133 lifts and falls so that the blowing component 411 (including the blowing components 4111 arranged in pairs) fixed thereon also rises and falls accordingly, and when the tableware rises to the primary polishing area 412, the blowing component 411 begins to release airflow, and then the first driving member 4131 reverses, gradually driving the lifting platform 4133 and the blowing component 411 to return to the initial position, thereby realizing the polishing operation of the tableware from top to bottom. During the process, the blowing component 411, driven by the lifting platform 4133, can move from top to bottom while polishing the tableware, and this dynamic polishing method helps to remove impurities and defects on the surface of the tableware more evenly. At the same time, since the blowing component 411 can be closely attached to the surface of the tableware, it can act more deeply on the tiny uneven areas and improve the polishing quality. Moreover, this design enables the polishing equipment to adapt to tableware of different heights and shapes and has a wider range of applications.

[0082] Secondary polishing assembly 420:

[0083] See also Figure 6 and Figure 7 The secondary polishing component 420 is a device for further refining the surface of the tableware. After the primary polishing removes excess glue, the secondary polishing component 420 uses a more refined polishing process to make the surface of the tableware reach a higher gloss and present a brighter effect. The fine processing of the secondary polishing component 420 helps to eliminate tiny defects that may be left during the primary polishing process, thereby improving the overall polishing quality.

[0084] For tableware, in order to adapt to its irregular shape and ensure a better polishing effect, the secondary polishing component 420 can be an air suction device, which can absorb the undried glue and attached debris and dust on the surface of the tableware.

[0085] In the present invention, the secondary polishing assembly 420 includes an air suction component 421 disposed below the tableware. The air suction component 421 sucks air from the passing tableware from below, and uses the power of negative pressure to further refine the polishing effect and improve the overall polishing quality.

[0086] The structure of the air suction component 421 is not limited. In one embodiment, the air suction component 421 includes an air suction module that is movably arranged on the bottom of the frame 100. A strip-shaped air suction port is formed at the top of the air suction module. The strip-shaped air suction port extends perpendicular to the conveying direction, and the air suction module can be connected to the negative pressure generator pipeline. The negative pressure generator acts on the air suction module to make the strip-shaped air suction port generate adsorption force to achieve re-adsorption of the tableware.

[0087] The suction component 421 can be fixedly set on the frame 100, with the strip-shaped suction port facing the bottom end of the tableware, or the suction component 421 can be movably set on the frame 100. When the tableware passes through the suction component 421, the suction component 421 first moves in the direction where the tableware is sent, and then moves synchronously with the tableware.

[0088] In one embodiment, the suction component 421 is movably disposed on the frame 100, and the secondary polishing assembly 420 includes a second driving member 422, which is disposed on the frame 100 and can drive the suction component 421 to reciprocate relative to the bottom of the frame 100 along the conveying direction; when the suction component 421 sucks air from the passing tableware from below, the second driving member 422 drives the suction component 421 and the tableware to move in the opposite direction, and this relative movement helps the suction component 421 to apply suction to the tableware more evenly, thereby better removing minor defects on the surface of the tableware and improving the polishing quality.

[0089] The suction component 421 is not limited to the above structure, but can also be other devices with suction function, such as a suction nozzle, as long as it can suck air from the bottom of the tableware to fix the tableware and assist in polishing. The second driving member 422 can be a motor, a cylinder or other driving device that can produce linear or reciprocating motion.

[0090] Furthermore, in the utility model, the first-level polishing assembly 410 and the second-level polishing assembly 420 can also be provided with a movable seat, which is slidably connected to the bottom bracket 140 of the frame 100 along the tableware conveying direction 101 through the movable seat. Specifically, the bottom bracket 140 can be provided with a slide rail, and the movable seat has an adaptive slider; when in use, the position of the first-level polishing assembly 410 and the second-level polishing assembly 420 in the tableware conveying direction 101 can be adjusted according to different process requirements, so as to meet different process production requirements.

[0091] Furthermore, in order to further improve the polishing effect, the polishing device 400 also includes a pushing component 430 arranged between the primary polishing component 410 and the secondary polishing component 420. The pushing portion 432 at the top of the pushing component 430 extends perpendicular to the conveying direction, and the top of the pushing component 430 is higher than the bottom end of the tableware passing through it in the vertical direction. The side wall of the tableware being conveyed and passing through will be pushed and collided with the pushing portion 432, so that the glue droplets hanging at the bottom of the tableware can fall naturally through shaking.

[0092] The push member 430 can be made of a strong and durable material, such as metal or high-strength plastic, and a push portion 432 is provided at its top, and the push portion 432 extends perpendicular to the conveying direction, such as extending along the width direction of the frame 100. The push portion 432 is a component that contacts the side wall of the tableware, and its shape and size can be designed according to the shape and size of the tableware to ensure the push effect.

[0093] In one embodiment, the pushing component 430 includes a movable frame 431 and a third driving member 433, the pushing portion 432 is configured as a steel wire, the movable frame 431 is movably disposed on the bottom of the frame 100 along the conveying direction, the steel wire is fixedly connected to the top of the movable frame 431 along the width direction of the frame 100, and the third driving member 433 is used to drive the movable frame 431 to move.

[0094] Specifically, the third driving member 433 is fixed on the frame 100, and the controller can be used to control the third driving member 433 to drive the movable frame 431 to move back and forth along the conveying direction in conjunction with the steel wire. When the side wall of the tableware being conveyed pushes and collides with the steel wire, the third driving member 433 drives the movable frame 431 to move in the opposite direction to the tableware. A first slide rail 4341 extending along the conveying direction is provided at a position corresponding to the movable frame 431 on the bottom of the frame 100, and a first slider 4342 adapted to the first slide rail 4341 is provided at the bottom of the movable frame 431, and the first slider 4342 is slidably adapted to the first slide rail 4341. Driven by the third driving member 433, the movable frame 431 (and the steel wire) can move back and forth along the conveying direction, forming a continuous pushing and colliding process with the tableware, which helps to increase the success rate of the glue drop at the bottom of the tableware falling off.

[0095] Similarly, a second slide rail 4231 extending along the conveying direction is provided at a position corresponding to the suction component 421 on the bottom of the frame 100, and a second slider 4232 adapted to the second slide rail 4231 is provided at the bottom of the suction component 421, and the second slider 4232 is slidably adapted to the second slide rail 4231. Driven by the second driving member 422, the suction component 421 can reciprocate along the conveying direction, and this relative movement helps the suction component 421 to apply suction to the tableware more evenly, thereby better removing minor defects on the surface of the tableware and improving the polishing quality.

[0096] The distance between the push portion 432 and the bottom of the tableware passing through it satisfies: h / 6≤L≤h / 3; where h is the length of the tableware; L is the distance from the push portion 432 to the bottom of the tableware. With such a configuration, when the tableware passes through the push portion 432, the push portion 432 can collide with the tableware to make it shake, thereby achieving the drop of glue at the end of the tableware falling, while preventing the push portion 432 from blocking the tableware and causing it to get stuck.

[0097] It should be understood that the present invention does not impose any requirements on the specific size of the distance between the push portion 432 and the bottom end of the tableware passing therethrough, as long as the above requirements are met.

[0098] About Gluing Device 300:

[0099] See also Figure 5 , the gluing device 300 is located below the gluing station 110 and the conveying device 200, and its main function is to accurately apply an appropriate amount of glazing glue or paint on the surface of the tableware. In the glazing equipment provided by the utility model, the gluing device 300 is located upstream of the polishing device 400. When the tableware is transported to the gluing station 110 by the conveying device 200, the gluing device 300 will accurately apply the glazing glue or paint on the surface of the tableware. Then, the tableware will continue to be transported by the conveying device 200 to the polishing station 120 for polishing, and finally dried in the drying station 130. Through this continuous automated production process, the production efficiency and quality stability can be greatly improved.

[0100] The gluing device 300 may specifically be a gluing head, a gluing tank 320, etc. If a gluing head is used, the shape and size of the gluing head can be customized according to the shape and size of the tableware to ensure the best coating effect. For example, the gluing head can be a roller type, a nozzle type, a scraper type, etc. For example, for small tableware glazing equipment, a simple roller type gluing head can be used to control the uniformity and thickness of the glue coating by adjusting the pressure and speed of the roller. For large or complex-shaped tableware, a more complex nozzle type or scraper type gluing head may be required to ensure that every corner and detail can be fully coated.

[0101] In one embodiment of the present utility model, the gluing device 300 includes a second lifting component 310 disposed at the bottom of the frame 100 and a gluing groove 320 disposed at the lifting end of the second lifting component 310; when the tableware passes through the gluing station 110 and above the gluing groove 320, the second lifting component 310 drives the gluing groove 320 to move from bottom to top, and the tableware is immersed in the gluing groove 320 as a whole. The second lifting component 310 includes a second screw assembly 311 and a fourth drive member 312; the fourth drive member 312 is fixedly disposed on the frame 100 and located on one side of the gluing groove 320, the second screw assembly 311 includes a screw rotatably erected on the bottom of the frame 100, and a nut sleeved on the screw, the gluing groove 320 is fixedly connected to the nut of the second screw assembly 311, and the drive shaft of the fourth drive member 312 is transmission-connected to the screw in the second screw assembly 311.

[0102] In the initial state of the gluing device 300, the gluing groove 320 is fixedly connected to the nut of the second screw assembly 311 and is located at a lower position at the bottom of the frame 100. When the tableware reaches the top of the gluing station 110, the fourth driving member 312 starts to work, and the driving shaft of the fourth driving member 312 is connected to the screw in the second screw assembly 311 to drive the screw to rotate. Since the nut is sleeved on the screw and forms a threaded fit with the screw, when the screw rotates, the nut will move along the axial direction of the screw. As the nut moves, the gluing groove 320 (fixedly connected to the nut) also rises and falls accordingly. Driven by the second lifting component 310, the gluing groove 320 moves from bottom to top until the tableware is immersed in the gluing groove 320 as a whole. During the process of the tableware being immersed in the gluing groove 320, the glue in the gluing groove 320 will be evenly adhered to the surface of the tableware, and the gluing effect will be better. When the tableware is finished being glued, the fourth driving component 312 works in the reverse direction, driving the screw rod to rotate, so that the nut and the gluing groove 320 move in opposite directions, and the gluing groove 320 gradually drops back to the initial position to prepare for the next round of gluing process.

[0103] In this embodiment, the lifting speed and gluing time of the gluing groove 320 can be controlled by adjusting the driving speed of the fourth driving member 312 and the pitch of the screw rod. The specific design can be set according to actual needs and usage requirements, and this embodiment is not the only requirement.

[0104] About drying device 500:

[0105] See also Figure 1 , Figure 2 , Figure 8 The drying device 500 is used to dry the tableware after gluing and polishing to ensure that the coating on its surface can be quickly cured to achieve the expected glossiness and durability.

[0106] Specifically, the drying device 500 provides a high temperature environment for the entire equipment, accelerates the evaporation process of moisture and residual glue on the surface of the tableware, and makes the tableware reach a dry state in a short time. The drying process helps the chemicals in the coating to react and solidify it quickly, thereby enhancing the adhesion and durability of the coating.

[0107] The drying device 500 is located below the drying station 130 and the conveying device 200, and includes a drying chamber 510 for drying the tableware conveyed through the drying chamber 510. The drying device 500 may further include a drying chamber 510, a heating system, a temperature control system, an exhaust system, and a safety device.

[0108] Specifically, the drying chamber 510 is the main part of the drying device 500, which is a closed environment for accommodating and drying tableware. The drying chamber 510 can be made of high temperature resistant materials to ensure that it can withstand long-term work in a high temperature environment. The heating system provides a high temperature environment to accelerate the evaporation of water, and can be heated by resistance heating, hot air circulation, etc. Among them, the hot air circulation method improves the drying efficiency by circulating hot air, and also helps to evenly distribute heat. The temperature control system is used to monitor and adjust the temperature in the drying chamber 510 to ensure that its temperature remains within a suitable range. It may include a temperature sensor and a temperature regulator, and the operator can use the temperature regulator to adjust the drying temperature as needed. The exhaust system is used to discharge the steam and harmful gases generated during the drying process from the drying chamber 510 to keep the interior clean and dry. The exhaust system can be an exhaust port and a fan or an exhaust pump. The safety device can be an overheating protection device, a temperature sensor fault alarm device, etc., which can cut off the power supply or sound an alarm in time when an abnormal situation occurs (for example, when the temperature is too high or too low), thereby avoiding equipment damage or casualties.

[0109] It should be understood that the present invention does not impose a single requirement on the specific configuration of the drying chamber 510, heating system, temperature control system, exhaust system and safety device (not shown), which can be specifically configured according to process requirements such as the production volume of tableware.

[0110] Furthermore, when the drying chamber 510 is specifically designed, the drying chamber 510 may be arranged below the conveying device 200, and the drying chamber 510 includes a plurality of sub-chambers 511 arranged in sequence along the tableware conveying direction 101, such as 3, 4, etc.; a heating module 520 is arranged in each sub-chamber 511; this design can more accurately control the temperature and time of each area, thereby ensuring that the tableware can be dried evenly and quickly during the conveying process, and the design of partitioned drying can adjust the heating power and working time of each sub-chamber 511 according to the actual needs of the tableware, and can ensure that the glue or coating on the surface of the tableware will not be damaged due to excessive temperature during the drying process, thereby maintaining the appearance and quality of the product. At the same time, partitioned drying can also reduce problems such as deformation and cracking of tableware during the drying process, and improve the yield rate and quality stability of the product. And the design of multiple sub-chambers 511 can be flexibly adjusted according to the shape, size and material of different tableware. For example, for larger or thicker tableware, the drying time and heating power may be appropriately increased or the number of activated drying chambers 510 may be increased; and for smaller or thinner tableware, the drying time and heating power may be reduced or the number of activated drying chambers 510 may be reduced.

[0111] For further information, see Figure 1 to Figure 2 Since the adhesion of varnish or gloss glue is strong, the utility model provides a shell 600 outside the conveying device 200, the gluing device 300, the polishing device 400 and the drying device 500. The shell 600 can prevent external dust from entering the device, keep the surface of the tableware inside the device clean, reduce dust accumulation, and thus improve the gloss of the tableware.

[0112] In addition, the housing 600 can effectively isolate the operating parts inside the device, prevent the operator from being injured due to accidental or accidental contact, and protect the internal device from physical impact and damage from the external environment, such as collision, scratches, etc.

[0113] In addition, the housing 600 can also reduce noise during operation of the equipment and provide a better working environment for operators.

[0114] In summary, the tableware polishing equipment provided by the utility model, the conveying device 200, the gluing device 300, the polishing device 400 and the drying device 500 cooperate with each other to form a continuous and automated production process. When the tableware is polished, the tableware can enter from the material inlet 1011, pass through each station in sequence, and finally output from the material outlet 1012. The whole process does not require manual intervention, which greatly improves the production efficiency. In particular, the polishing device 400 includes a primary polishing component 410 and a secondary polishing component 420 arranged in sequence along the tableware conveying direction 101. The primary polishing component 410 includes a blowing component 411 arranged on the frame 100, and the blowing component 411 blows the tableware passing from top to bottom; the secondary polishing component 420 includes an air suction component 421 arranged below the tableware, and the air suction component 421 sucks the tableware passing from below; the polishing device 400 adopts a combination of the primary polishing component 410 and the secondary polishing component 420. The first-level polishing assembly 410 blows air into the tableware through the blowing component 411 to remove excess glue or impurities; the second-level polishing assembly 420 sucks air into the tableware through the suction component 421 to further refine the polishing effect. This combination not only improves the polishing efficiency, but also ensures the polishing quality; and the first-level polishing assembly 410 and the second-level polishing assembly 420 of the polishing device 400 perform fine polishing on the tableware through blowing and suction. The first-level polishing removes excess glue, and the second-level polishing further refines the surface gloss, making the surface of the tableware smoother and brighter, which not only has the advantages of high polishing efficiency, but also has the advantages of good polishing effect.
