Description

Technical Field

[0001] The invention relates to the field of wine bottle processing, and in particular to a return wheel chain hanging closed environmentally friendly full-automatic wine bottle glaze spraying equipment. Background Art

[0002] Spray glazing is a modern ceramic glazing technique. Glaze slurry is atomized and sprayed onto the surface of the ceramic body using a spray gun or atomizer. This glazing method is suitable for large products, complex shapes, or thin-walled products that require multiple glazing applications. Multiple sprays can be used to apply multiple glaze colors and achieve a thicker coating. Many tile factories currently use this method for glazing. Another mechanical glazing method combines pouring and spraying, achieving high efficiency and a smooth, even glaze surface. Automated spray glazing is commonly used for glazing large sanitary ware bodies.

[0003] There are many types of glazes. According to their composition, they can be divided into lime glaze, feldspar glaze, lead glaze, zirconium glaze, boron glaze, lead-boron glaze, salt glaze and earth glaze. According to their appearance, they can be divided into transparent glaze, opaque glaze, colored glaze, crystalline glaze, gold sand glaze, matte glaze and crackle glaze. The colors of colored glazes are diverse, including red, yellow, blue, white, black and blue and white. When some raw materials in the glaze are frits and finely ground into glaze slurry, it is called frit glaze. The glazing method generally adopts dipping, spraying and coating to evenly cover the glaze slurry on the body and then glaze firing. The glaze layer can make the surface of the product smooth, waterproof and not easy to be contaminated, and it can also improve the mechanical strength, electrical properties, chemical stability and thermal stability of the product to a certain extent. In the production process of ceramic wine bottles, the glaze is sprayed onto the surface of the body in the form of glaze mist from top to bottom through the nozzle under the pressure of compressed air, so that the glaze is evenly adhered to the surface of the wine bottle.

[0004] Currently, there are two common methods for spraying glaze on wine bottles: one is to place the bottom of the wine bottle on a rotating tray, but the wine bottle is easily slipped off the tray due to the centrifugal force during the spraying process, and an additional process is required to spray the bottom of the wine bottle after spraying the bottle body; the other is to place the bottle mouth on a rotating shaft. Although this can achieve uniform glaze spraying around the bottle, because the wine bottle only rotates on one plane, it is necessary to frequently adjust the height of the spray gun. Moreover, because the wine bottle is inserted into a rotating shaft, it is difficult to spray glaze inside.

[0005] The authorization announcement number is: CN214735401U, a new patent document. The utility model belongs to the technical field of glaze spraying devices and discloses a glaze spraying device for wine bottle production, including a stirring device, wherein a motor box is provided on the left side of the stirring device, a stirring rod motor is fixedly installed inside the motor box, and an output shaft of the stirring rod motor is fixedly connected to a stirring rod that penetrates the stirring device, the surface of the stirring rod is welded with a stirring rod, and the surface of the threaded rod is threadedly connected with a movable seat, which can fully stir the glaze slurry. A material guide pipe is provided at the lower end of the stirring device, and a glaze spraying head is fixedly installed at the lower end of the material guide pipe, and a fixing frame is welded on the top of the glaze spraying head, and mounting cylinders are fixedly installed on the left and right sides of the inner wall of the fixing frame, and a compression spring is welded on the inner wall of the mounting cylinder, and a top plate is welded on the other end of the compression spring, and a shift rod is welded on the front of the top plate, and a clamping rod is fixedly installed on the side of the top plate, which is convenient for replacing the spray head.

[0006] At present, when spraying glaze on wine bottles, this solution simply places the bottles without fixing them, causing them to easily tip over and be damaged during the rotating spraying process. In addition, when spraying glaze on the wine bottles, only the surface can be glazed, and the inside of the wine bottle needs to be manually turned over and glazed a second time. This method is not only troublesome, but also increases the workload of the staff and is very inconvenient to operate. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the present invention provides a return wheel chain hanging closed environmentally friendly fully automatic wine bottle glaze spraying equipment, which solves the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a closed, environmentally friendly, fully automatic wine bottle glazing device with a rotating chain, comprising a rotating chain, a limiting frame, an adjustment assembly, an inner glazing assembly, and an outer glazing assembly.

The wine bottle moving assembly includes a movable ring that is sleeved on the through-type air outlet pipe and elastically slides relative thereto.

[0009] The adjustment assembly is installed on the limiting frame. The adjustment assembly includes two sets of electric push rods and a dial plate fixed to the output shaft of the electric push rod. The two dial plates are arranged in parallel, and there is a gap between the two for the movable ring to pass through. When the dial plate moves downward, the movable ring can be moved downward. The inner glaze spraying assembly is installed at the bottom of the limiting frame and is used to spray glaze to the bottom of the through-type air outlet pipe. The outer glaze spraying assembly is installed on one side of the limiting frame.

[0010] Preferably, the rotary chain further comprises a single chain group, a gear and a traveling wheel, the gear and the traveling wheel are both installed in the single chain group and rotatably connected thereto, and the through-type air outlet pipe is fixedly inserted through the center of the gear.

[0012] Preferably, the limiting frame includes a frame base, a rack and a U-shaped track. The rack is parallel to the U-shaped track and both are suspended above the frame base. The single chain group passes between the U-shaped track and the rack, the gear is engaged with the rack, and the traveling wheel is in contact with the U-shaped track.

[0013] Preferably, the two sets of electric push rods are fixed to the U-shaped track and the rack respectively.

[0014] Preferably, the internal glaze spraying assembly includes an up-and-down motion assembly and a glaze nozzle installed on the up-and-down motion assembly. The up-and-down motion assembly is used to realize the up-and-down motion of the glaze nozzle, and can move the glaze nozzle upward and insert it into the through-type air outlet pipe.

[0015] Preferably, the up-and-down motion assembly includes a motor and a slider-crank mechanism, and the operation of the motor causes the slider-crank mechanism to operate and drives the glaze nozzle to move up and down.

The wine bottles can be buckled on the through-type air outlet pipe, and the movable ring can limit the insertion depth of the wine bottles. Therefore, when the single chain group moves, the gear can drive the wine bottles to rotate, so the outer glaze spraying assembly can evenly spray glaze on the outer ring of the wine bottle, and the electric push rod can also use the dial plate to lower the height of the wine bottle, so all positions of the wine bottle can be sprayed with glaze. Since the rack and U-shaped track are used to clamp the single chain group, in actual use, the rack and U-shaped track can be extended, so the single chain group is very stable during operation, and the rotation rate of the wine bottle is based on the moving speed of the single chain group, and no additional power components are required.

[0020] 2. This return wheel chain hanging closed environmentally friendly fully automatic wine bottle glaze spraying equipment, when the single chain group moves the wine bottle to the inner glaze spraying assembly, the motor drives the glaze nozzle to move upward and insert it into the through-type air outlet pipe, thereby spraying glaze to the inside of the wine bottle through the through-type air outlet pipe. At the same time, the electric push rod not only facilitates uniform glaze spraying on the outside, but also changes the depth of the through-type air outlet pipe inserted into the inside of the wine bottle, so that the external glaze spraying can be achieved uniformly, and the internal glaze spraying can also achieve a uniform effect.

[0021] 3. The return wheel chain hanging closed environmentally friendly fully automatic wine bottle glaze spraying equipment is equipped with a limiting frame and an adjustment component. The limiting frame and the adjustment component can be set to multiple first-connected ones, so the wine bottle can pass through all the limiting frames and adjustment components smoothly. At the same time, it will not affect the movement of the wine bottle to the downward process during processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figures 1-8 As shown, a closed, environmentally friendly, fully automatic wine bottle glazing device with a rotating chain is provided, comprising a rotating chain 1, a limiting frame 2, an adjustment assembly 3, an inner glazing assembly 4, and an outer glazing assembly 5. The rotating chain 1 comprises a through-type air outlet pipe 101 and a wine bottle moving assembly 102 mounted on the through-type air outlet pipe 101. When the rotating chain 1 passes the upper end of the limiting frame 2, the through-type air outlet pipe 101 can rotate. The wine bottle moving assembly 102 comprises a movable ring 1023, which is sleeved on the through-type air outlet pipe 101 and elastically slides relative thereto.

[0036] The adjustment component 3 is installed on the limiting frame 2. The adjustment component 3 includes two groups of electric push rods 301 and a dial plate 302 fixed to the output shaft of the electric push rod 301. The two dial plates 302 are arranged in parallel, and there is a gap between the two for the movable ring 1023 to pass through. When the dial plate 302 moves downward, the movable ring 1023 can be moved downward. The internal glaze spraying component 4 is installed at the bottom of the limiting frame 2 and is used to spray glaze to the bottom of the through-type air outlet pipe 101. The external glaze spraying component 5 is installed on one side of the limiting frame 2.

[0037] Currently, glazing needs to be carried out in a closed box. Therefore, the limiting frame 2, adjustment component 3, inner glazing component 4 and outer glazing component 5 of this scheme are also arranged in a box, and the above structure can be selected to set up multiple groups according to the uniformity of glazing. The first connection between each two groups is generally required to ensure the quality of glazing. No less than six groups are required. The rotary chain 1 is a unit on the entire chain, and the through-type air outlet pipe 101 is a hollow tubular structure with a gentle conical structure at the upper end, which is convenient for the grabbing equipment to insert the wine bottle.

[0038] The outer glaze spraying assembly 5 is an existing structure, which is fixed to the limiting frame 2 by a long screw. The glaze spraying equipment is installed on the long screw by bolts and can be changed in height.

[0039] In an optional embodiment, the rotary chain 1 also includes a single chain group 103, a gear 104 and a traveling wheel 105. The gear 104 and the traveling wheel 105 are both installed in the single chain group 103 and rotatably connected thereto, and the through-type air outlet pipe 101 is fixedly inserted in the center of the gear 104.

[0040] In this embodiment, each single chain group 103 is the same and can form a complete chain after combination. The combined chain can still be driven by a sprocket. The chain can only pass through the restriction frame 2 when it is not passing through the sprocket position and is in linear motion.

[0041] In an optional embodiment, the wine bottle moving assembly 102 includes a fixed ring 1021 and a spring 1022. The longitudinal section of the movable ring 1023 is I-shaped. The fixed ring 1021 is sleeved on the outside of the through-type air outlet pipe 101 and fixed to the through-type air outlet pipe 101. The spring 1022 connects the movable ring 1023 and the movable ring 1023. When the movable ring 1023 moves downward, it can compress the spring 1022.

[0042] In this embodiment, the fixed ring 1021 is fastened to the outside of the through-type air outlet pipe 101 by bolts, and lubricating oil is applied between the movable ring 1023 and the through-type air outlet pipe 101. When the movable ring 1023 moves downward, the spring 1022 can be compressed. When the movable ring 1023 is not under force, the reaction force of the spring 1022 can lift the movable ring 1023 and restore it to its original position.

[0043] In an optional embodiment, the limiting frame 2 includes a frame base 201, a rack 202 and a U-shaped track 203. The rack 202 is parallel to the U-shaped track 203 and both are suspended above the frame base 201. The single chain group 103 passes between the U-shaped track 203 and the rack 202. The gear 104 engages with the rack 202, and the traveling wheel 105 contacts the U-shaped track 203.

[0044] In this embodiment, the rack 202 and the U-shaped track 203 are parallel to each other, and there is a space for the single chain group 103 to pass through. When the single chain group 103 passes through, the traveling wheel 105 fits into the U-shaped track 203, so that the gear 104 can engage with the rack 202.

[0045] In an optional embodiment, two groups of electric push rods 301 are fixed to the U-shaped track 203 and the rack 202 respectively.

[0046] In this embodiment, the electric push rod 301 is a linear motion component that can ensure the back-and-forth motion of the shift plate 302. The electric push rod 301 can also be replaced with other linear motion components such as a cylinder. The ends of the shift plates 302 that are close to each other are chamfered, so the movable ring 1023 hardly generates friction with the shift plate 302 when passing through.

[0047] In an optional embodiment, the internal glaze spraying assembly 4 includes an up and down motion assembly 401 and a glaze nozzle 402 installed on the up and down motion assembly 401. The up and down motion assembly 401 is used to realize the up and down movement of the glaze nozzle 402, and can move the glaze nozzle 402 upward and insert it into the through-type air outlet pipe 101.

[0048] In this embodiment, the outer diameter of the glaze nozzle 402 is smaller than the inner diameter of the through-type air outlet pipe 101, the upper end diameter of the glaze nozzle 402 is thinner and the lower end diameter is thicker. When the glaze nozzle 402 is fully inserted into the through-type air outlet pipe 101, its bottom will seal the through-type air outlet pipe 101. When the glaze nozzle 402 is inserted and sprays glaze, it will not adhere to the through-type air outlet pipe 101.

[0049] The glaze spraying pipe 402 is connected to the existing glaze spraying equipment when in use and needs to be supplied by a high-pressure gas line.

[0050] In an optional embodiment, the up-and-down motion assembly 401 includes a motor 4011 and a crank slider mechanism 4012 . The operation of the motor 4011 causes the crank slider mechanism 4012 to operate and drive the glaze nozzle 402 to move up and down.

[0051] In an optional embodiment, two traveling wheels 105 are provided, and the gear 104 is located between the two traveling wheels 105 , and the distance between the gear 104 and any one of the traveling wheels 105 is the same.

[0052] In this embodiment, the traveling wheel 105 and the gear 104 both protrude from the single chain assembly 103 in opposite directions, and the protrusion of the traveling wheel 105 can cooperate with the sprocket for transportation.

[0053] In an optional embodiment, two longitudinal beams 204 are fixedly installed on the rack 202 and the U-shaped track 203. The longitudinal beam 204 connected to the rack 202 is fixed to the frame base 201, and the longitudinal beam 204 connected to the U-shaped track 203 is connected to the frame base 201 with bolts. The frame base 201 is provided with a long groove corresponding to the bolt for adjusting the U-shaped track 203.

[0054] In this embodiment, the U-shaped track 203 can be adjusted by bolts, so the force of clamping the single chain assembly 103 can be changed.

[0055] When in use, several single chain groups 103 are combined into a whole chain, and in order to ensure the quality of glazing, a plurality of limiting frames 2, adjustment components 3, inner glazing components 4 and outer glazing components 5 are also provided, generally six groups are sufficient, and when glazing, the wine bottle can be buckled on the through-type air outlet pipe 101, and the movable ring 1023 can limit the insertion depth of the wine bottle, and when the single chain group 103 moves, the gear 104 engages the rack 202, so that the through-type air outlet pipe 101 can rotate with the wine bottle, so that the outer glazing component 5 can spray glaze evenly on the outer ring of the wine bottle, and when the single chain group 103 moves with the wine bottle, the movable ring 1023 can pass between the two dial plates 302, so that it does not affect the movement of the single chain group 103 with the wine bottle, and the electric push rod 301 can also use the dial plate 302 to lower the height of the wine bottle, so all positions of the wine bottle can be achieved Glaze spraying. Similarly, when the single chain group 103 moves to the glaze nozzle 402 corresponding to the through-type air outlet pipe 101, it can pause for a while, and the motor 4011 drives the glaze nozzle 402 to move up and insert it into the through-type air outlet pipe 101, thereby spraying glaze to the inside of the wine bottle through the through-type air outlet pipe 101. At this time, the electric push rod 301 can continue to operate to change the height of the wine bottle. After the internal glaze spraying is completed, the single chain group 103 continues to operate. After crossing the glaze nozzle 402, the electric push rod 301 continues to operate to achieve uniform glaze spraying on the outside. Since the through-type air outlet pipe 101 is inserted into the inside of the wine bottle, even if the wine bottle does not rotate, when spraying the glaze inside, uniform glaze spraying can be achieved. While the electric push rod 301 facilitates uniform glaze spraying on the outside, it also changes the depth of the through-type air outlet pipe 101 inserted into the inside of the wine bottle, so the glaze spraying on the outside and the inside is uniform.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.
