Abstract

The present application relates to the technical field of glass bottle production, and discloses a light-weight glass bottle strength-increasing evaporation coating equipment, which comprises multiple ball hinge type raw material spraying structures, a driven reciprocating structure and multiple gear type glass bottle placing structures. The light-weight glass bottle strength-increasing evaporation coating equipment can spray the bottle body of the light-weight glass bottle, thereby increasing the strength of the glass bottle. When the glass bottle is sprayed, the bottle body of the glass bottle is rotated by 360 degrees, so that the spray head can perform full-range spraying on the same horizontal plane of the bottle body of the glass bottle. The spray head can also change the longitudinal angle reciprocally, so that the spray head can perform full-range spraying on the vertical plane of the bottle body of the glass bottle. The full-range spraying on the horizontal plane and the full-range spraying on the vertical plane can comprehensively evaporate and coat the bottle body of the glass bottle, thereby effectively improving the uniformity of the coating after evaporation and coating and improving the overall quality strength of the glass bottle after evaporation and coating.

Description

Technical Field

[0001] This invention relates to the field of glass bottle production technology, specifically to a vapor coating device for increasing the strength of lightweight glass bottles. Background Technology

[0002] Many glass products, after being processed into finished products, do not meet the hardness and wear resistance requirements of our daily lives. Therefore, further processing is necessary. The common method is to coat the surface of the glass with a coating, typically using a hot-end vapor coating machine.

[0003] For example, Chinese patent publication number "CN203355983U" discloses "A Hot-End Steam Coating Machine," whose main structure includes symmetrical cooling chambers. A circulation chamber is located on one side of the cooling chambers, and the circulation chamber is equipped with a first circulation door, a second circulation door, a third circulation door, and a fourth circulation door. A first circulation motor, a second circulation motor, a third circulation motor, and a fourth circulation motor are respectively installed on the first, second, third, and fourth circulation doors. A circulation pipe is installed on the upper part of the circulation chamber. Compared with existing technologies, the above-mentioned hot-end steam coating machine has the following advantages: it eliminates the need to move or disassemble the steam coating hood, does not affect normal production, and is very time-saving and labor-saving; the baffles formed between the suction ports are thinner, reducing the adhesion of raw materials to the baffles during the suction process, resulting in less scaling and higher raw material utilization.

[0004] In actual operation, when the hot-end vapor coating machine sprays raw materials, the raw materials are fed into the supply pipe and enter the circulation chamber through a three-way valve. Under the action of the first, second, third, and fourth circulation motors, the raw materials in the circulation chamber are sprayed onto the high-temperature glass bottle through the cooling chamber. In other words, the spraying direction of the raw materials is from one side of the glass bottle to the other side. This results in the coating on the side of the glass bottle facing the atomized raw materials being larger than the coating on the other side of the glass bottle, leading to poor uniformity of the raw material coating thickness and affecting the quality of the finished product. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a vapor coating device for increasing the strength of lightweight glass bottles. This device can spray coatings onto the body of lightweight glass bottles, thereby increasing their strength. During spraying, the bottle body rotates 360 degrees, allowing the spray nozzle to perform omnidirectional spraying on the bottle body at the same horizontal plane. Simultaneously, the spray nozzle can reciprocate with longitudinal angle changes, enabling omnidirectional vertical spraying on the bottle body. This combination of horizontal and vertical omnidirectional spraying achieves comprehensive vapor coating of the glass bottle body, effectively improving the uniformity of the coating after vapor coating and enhancing the overall quality and strength of the vapor-coated glass bottle, thus solving the aforementioned technical problems.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1A lightweight glass bottle strengthening vapor coating device includes a hollow bottom support base plate 1 with support legs 2 mounted on the bottom, a drive motor 3 fixedly mounted on the bottom of the hollow bottom support base plate 1, a polygonal hollow column 13 fixedly mounted at the center of the upper surface of the hollow bottom support base plate 1, a linear motor 11 fixedly mounted on the top of the polygonal hollow column 13, a gear mounting cavity 5 disposed inside the hollow bottom support base plate 1, a gas flow channel 6 disposed on one side of the gear mounting cavity 5, a bottom raw material flow cavity 14 disposed inside the polygonal hollow column 13, a raw material injection channel 18 disposed at the top of the bottom raw material flow cavity 14, an isolation cover 7 clamped above the hollow bottom support base plate 1 along the side of the polygonal hollow column 13, an isolation cavity 8 disposed inside the isolation cover 7, a cooling channel 9 disposed on the side of the isolation cover 7, and a gear mounting cavity 5 located in the gear mounting cavity 13. Before operation, the main gear 10, which is installed inside the rotating rotor 4 of the drive motor 3, needs to connect the raw material injection channel 18 to the discharge port of the pump body that discharges the spraying material. The pump body needs to have pressure output capability to discharge the material used for spraying the glass bottle body at a certain pressure. The gas flow channel 6 needs to be connected to the suction port of a suction device. The suction device can extract the gas inside the gear mounting cavity 5 and reduce the gas pressure inside the gear mounting cavity 5 to form a low-pressure area. The strength of this low-pressure area needs to be sufficient to ensure that the bottom of the glass bottle is stably adsorbed on the annular end face of the annular rubber pad 176. The cooling channel 9 needs to be connected to the gas circulation port of a cooler that generates cooling gas. After the spraying work is completed, the cooler can be started to quickly cool the isolation cavity 8 and the glass bottle.

[0029] To achieve a vertical, all-around spray coating effect on the body of the glass bottle, please refer to [link / reference needed]. Figure 1 , Figure 2 and Figure 3Multiple ball-joint type material spraying structures 15 are required. Each structure contains annular insert blocks 151 arranged side-by-side on the sides of a polygonal hollow column 13; atomizing nozzles 157 that rotate around the center of the annular insert blocks 151 and spray material from the bottom material flow cavity 14 in an atomized manner; and a rectangular protrusion structure 155 located inside the bottom material flow cavity 14. When the bottom end face of the rectangular protrusion structure 155 is subjected to an upward force, the sphere 154 will rotate accordingly inside the annular insert blocks 151. During rotation, the atomized material... With the horizontal angle unchanged, the nozzle 157 flips from top to bottom, thus enabling the atomizing nozzle 157 to spray the bottle body from top to bottom. Similarly, when the top end face of the rectangular protrusion structure 155 is subjected to a downward force, the sphere 154 will rotate inside the annular insert block 151. When rotating, the atomizing nozzle 157 will flip from bottom to top with the horizontal angle unchanged, thus enabling the atomizing nozzle 157 to spray the bottle body from bottom to top, thereby achieving a vertical all-round spraying effect on the glass bottle body.

[0030] For details regarding the specific structure of the ball-joint type raw material spraying structure 15, please refer to [link / reference]. Figure 2 and Figure 3 The system includes an annular insert block 151 installed on the side of a polygonal hollow column 13. The annular insert block 151 has a spherical mounting groove 152 inside. To provide locking and limiting capabilities, the longitudinal center dimension of the spherical mounting groove 152 needs to be larger than the dimensions of its two open ends. A rotatable sphere 154 is placed inside the spherical mounting groove 152 within the annular insert block 151. To ensure stable rotation of the sphere 154 within the spherical mounting groove 152, it is best that the spherical structural radius of the sphere 154 matches the structural radius of the spherical mounting groove 152. This design also helps prevent material flow along the gaps and maintains... To ensure the static stability of the sphere 154 during operation, the annular insert block 151 needs to have a sealing ring 153 embedded on the outer surface of the sphere 154 to prevent gas from flowing along the gaps. The sphere 154 has an integral rectangular protrusion structure 155 on the surface inside the bottom raw material flow cavity 14. The other surface of the sphere 154 has an integral hollow connecting rod structure 156. The hollow connecting rod structure 156, the sphere 154, and the rectangular protrusion structure 155 have a raw material flow hole 158 communicating with the bottom raw material flow cavity 14. An atomizing nozzle 157 is installed at the end of the raw material flow hole 158.

[0031] To achieve longitudinal angle reciprocating control of the atomizing nozzle 157, thereby compensating for the spray gap caused by the installation gap between two adjacent atomizing nozzles 157, please refer to... Figure 1 and Figure 4 A driven reciprocating structure 16 needs to be set up, which contains a rectangular frame 164 that moves with the telescopic shaft 12 of the linear motor 11 and can drive the rectangular protruding structure 155 to change its longitudinal angle. When the linear motor 11 is started, the telescopic shaft 12 will drive the rectangular frame 164 to produce longitudinal reciprocating motion. When the rectangular frame 164 moves upward, the bottom end face of the rectangular protruding structure 155 is subjected to an upward force, so that the atomizing nozzle 157 sprays the bottle body from top to bottom. When the rectangular frame 164 moves downward, the top end face of the rectangular protruding structure 155 is subjected to a downward force, so that the atomizing nozzle 157 sprays the bottle body from bottom to top. This achieves a vertical all-round spraying effect on the bottle body, realizing the longitudinal angle reciprocating control function of the atomizing nozzle 157, thereby compensating for the spraying gap caused by the installation gap between two adjacent atomizing nozzles 157. The angle of reversal of the atomizing nozzle 157 is obtained by the range of longitudinal displacement of the rectangular frame 164.

[0032] For details regarding the specific structure of the driven reciprocating structure 16, please refer to [link / reference]. Figure 4 The system includes a longitudinal movable shaft 161 that runs through the longitudinal portion of the raw material injection channel 18 and extends into the bottom raw material flow cavity 14. The top end of the longitudinal movable shaft 161 is fixedly connected to the bottom end of the telescopic shaft 12 via a top fixing plate 162. A rectangular frame 164 is installed above and below each rectangular protrusion structure 155 via a transverse support rod 163. To ensure the longitudinal flowability of the sprayed raw material, the rectangular frame 164 needs to be a rectangular structure with a hollowed-out middle section. The inner surface of the rectangular frame 164 is connected to the shaft of the longitudinal movable shaft 161 via the transverse support rod 163. The hollowed-out section outside the transverse support rod 163 constitutes the raw material flow area. To ensure the directional driving capability of the rectangular frame 164 on the rectangular protrusion structure 155, the dimensions of the rectangular frame 164 need to meet the requirement that it causes an up-and-down angular change on the rectangular protrusion structure 155 during longitudinal movement.

[0033] To achieve a horizontal, all-around spray coating effect on the body of the glass bottle, please refer to... Figure 1 , Figure 5 and Figure 6Multiple gear-type glass bottle mounting structures 17 are required, arranged in a circular array around the axis of the polygonal hollow column 13. Inside each structure is a circular hollow shell 174 that rotates with the main gear 10 and, under the action of low-pressure gas, adsorbs the glass bottle onto its upper surface. Under the influence of low air pressure, the glass bottle is stably adsorbed above the circular hollow shell 174. When the drive motor 3 is started, it drives the main gear 10 to rotate. At the same time, due to the meshing of the tooth structure 172, the circular hollow shell 174 causes the glass bottle to rotate, achieving a horizontal all-round spraying effect on the glass bottle.

[0034] For details regarding the gear-type glass bottle mounting structure 17, please refer to [link / reference]. Figure 5 and Figure 6 The system includes a secondary gear 171 located inside the gear mounting cavity 5. To achieve linkage with the main gear 10, the secondary gear 171 needs to have a tooth structure 172 on its side that meshes with the main gear 10. A hollow shaft 173 is mounted on the upper end face of the secondary gear 171, penetrating the top structure of the bottom hollow support base plate 1. To prevent gas from flowing along the mounting gap and ensure airtightness, a mechanical seal structure is installed on the bottom hollow support base plate 1 at the part penetrated by the hollow shaft 173. An annular hollow section is mounted on the hollow shaft 173 above the bottom hollow support base plate 1. The housing 174 has a negative pressure chamber 175 with an open upper surface at its center. The auxiliary gear 171, the hollow shaft 173, and the annular hollow housing 174 have airflow holes 177 that connect the negative pressure chamber 175 and the space below the auxiliary gear 171. An annular rubber pad 176 is attached to the top annular end face of the annular hollow housing 174. In order for the annular rubber pad 176 to have a strong adsorption capacity for the bottom of the glass bottle, while not being melted by the high temperature of the glass bottle, the annular rubber pad 176 needs to be made of an elastic and high temperature resistant material.

[0035] In use, the raw material injection channel 18 needs to be connected to the discharge port of the pump body discharging the spraying material, the gas flow channel 6 needs to be connected to the suction port of a suction device, and the cooling channel 9 needs to be connected to the gas circulation port of a refrigeration unit that generates cooling gas. Place the glass bottles on the annular end faces of the respective annular rubber pads 176, and plug the bottle mouths with plungers. Then start the suction device to make the glass bottles tightly adhere to the upper annular end faces of the annular rubber pads 176. Then cover the bottom hollow support base plate 1 with the isolation cover 7, and then start the drive motor 3 and the linear motor 11. Then start the pump body to spray the vapor coating material onto the glass bottle body with an atomized effect. After the spraying work is completed, the refrigeration unit can be started to quickly cool the isolation chamber 8 and the glass bottle. After cooling, open the isolation cover 7 and turn off the suction device to remove the vapor-coated glass bottle.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
