Description

Technical Field

[0001] The invention relates to the technical field of glass bottle processing, and in particular to a glass bottle colored glaze spraying device and a spraying method. Background Art

[0002] Glass bottles and jars are packaging containers for food, beverages and many other products. They are also a very common decoration and are widely used.

[0003] Glass bottles have many excellent properties: transparent, easy to clean, good chemical stability, no pollution to contents, high air tightness, excellent storage performance, rich and colorful shapes and decorations, can be recycled many times, rich sources of raw materials, etc.

[0004] For glass bottles, in many cases, colored glaze is sprayed on the outside of the glass bottles to increase the beauty of the glass bottles, and at the same time facilitate subsequent painting, trademark printing, product information printing, etc. on the colored glaze surface.

[0005] At present, there are still some shortcomings in the glass bottle colored glaze spraying device: 1. At present, the glass bottle colored glaze spraying is to use the nozzle to spray the outer wall of the glass bottle with multiple points. This atomization spraying method has a poor atomization effect due to the relatively heavy particles of the colored glaze. During the spraying process, the colored glaze at the center point facing the nozzle is denser, and the sprayed colored glaze surface is thicker, resulting in uneven colored glaze on the outer wall of the glass bottle;

[0006] 2. During the glaze spraying process of glass bottles, a clamping tool is generally used to position the glass bottle. This clamping method will produce a certain contact with the outer wall of the glass bottle, resulting in a blank area for spraying at the position where the glass bottle contacts the clamping mechanism during the glaze spraying process. Subsequently, the blank area needs to be glazed, which affects the effect of the glass bottle spraying and reduces the efficiency of the spraying. Summary of the invention

[0007] The purpose of the present invention is to provide a glass bottle glaze spraying device to solve the problem that the current glass bottle glaze spraying is to use a nozzle to perform multi-point atomization spraying on the outer wall of the glass bottle. This atomization spraying method has a poor atomization effect due to the relatively heavy particles of the glaze. During the spraying process, the glaze at the center point directly facing the nozzle is denser and the sprayed glaze surface is thicker, resulting in uneven glaze on the outer wall of the glass bottle. During the glaze spraying process of the glass bottle, a clamping tool is generally used to position the glass bottle. This clamping method will produce a certain contact with the outer wall of the glass bottle, resulting in a blank area for spraying at the position where the glass bottle contacts the clamping mechanism during the glaze spraying process.

[0017] S1, first place the glass bottle on the rotating disk, and transport it to the spray room by using the transport trolley and the conveyor track, and use the stop mechanism to stop the transport trolley so that the transport trolley is directly below the driving mechanism. At this time, the lifting cylinder can be used to drive the lifting frame and the rotating disk to rise, so that the glass bottle on the rotating disk rises synchronously, and the limiting mechanism at the bottom of the rotating stud is inserted into the glass bottle. When the glass bottle rises to the bottom of the rotating stud, it squeezes the glass bottle and connects the glass bottle and the rotating stud through the limiting mechanism. At this time, the driving motor is started to drive the rotating stud to rotate, and the glass bottle and the rotating disk will rotate synchronously;

[0018] S2, when the glass bottle on the rotating disk rises, the limiting mechanism at the bottom end of the rotating stud is inserted into the glass bottle, and the bottoming slide will first squeeze the bottom of the glass bottle, so that the bottoming slide will slide up vertically, and the upward sliding of the bottoming slide will squeeze one end of the side pressing frame, so that the side pressing frame rotates around the installed shaft body, and the other end of the side pressing frame rotates and squeezes the inner wall of the glass bottle. The multiple side pressing frames squeeze the inner wall of the glass bottle in multiple directions, which can force the glass bottle to align with the bottom end of the rotating stud and maintain the same axis. Finally, the bottom end of the bottoming slide is tightly pressed against the inner bottom wall of the glass bottle, so that the top end of the bottoming slide is tightly pressed against one end of the side pressing frame, and the other end of the side pressing frame is tightly fitted into the inner wall of the glass bottle, so that the limiting mechanism at the bottom end of the rotating stud is tightly connected with the inner wall and bottom wall of the glass bottle. At this time, the rotation of the rotating stud will drive the glass bottle to rotate synchronously. Due to the connection between the glass bottle and the rotating disk, and the rotation characteristics of the rotating disk itself, the rotating disk will also rotate synchronously with the rotating stud and the glass bottle.

[0019] S3, during spraying, when the rotating stud, the glass bottle and the rotating disk rotate synchronously, the internal threaded tube and the mounting seat will move downward with the rotation of the rotating stud, driving the glaze spraying head to move downward synchronously. At this time, the glaze spraying head will be used to spray the rotating glass bottle with glaze.

[0021] The present invention, through the joint action of the driving mechanism inside the spraying chamber, the lifting mechanism on the transport trolley and the limiting mechanism, can make the glass bottle dock with the rotating stud of the driving mechanism as the lifting mechanism rises, and then use the limiting mechanism to further lock the position of the glass bottle at the end of the rotating stud, and use the rotating stud to drive the spraying assembly to move downward and drive the glass bottle to rotate synchronously, so as to form a uniform and top-to-bottom multi-layer spraying, and complete the uniform spraying of the colored glaze on the outer wall of the glass bottle;

[0022] The limiting mechanism of the present invention enables, after the glass bottle is lifted and the rotating stud is inserted into the interior of the glass bottle, the bottom-touching slide frame slides upward to squeeze the multiple side pressure frames to squeeze the inner wall of the glass bottle in multiple directions, thereby forming a tight connection between the rotating stud and the inner wall and the bottom wall of the glass bottle. The position of the glass bottle is fixed by the interior of the glass bottle, and there is no need to use a clamping mechanism on the periphery of the glass bottle, thereby avoiding the occurrence of spraying blanks on the outer wall of the glass bottle due to the clamping mechanism.

The lifting mechanism includes a lifting cylinder 9, a lifting frame 10 and a rotating disk 11. The lifting cylinders 9 are arranged at the inner corners of the transport trolley 5 in a group. The two ends of the lifting frame 10 are respectively connected to the lifting ends of the two lifting cylinders 9. The rotating disk 11 is installed on the lifting frame 10, and the rotating disk 11 is directly opposite to the bottom end of the rotating stud 8, so that the lifting cylinder 9 can drive the lifting frame 10 and the rotating disk 11 to rise, so that the rotating disk 11 is close to the bottom end of the rotating stud 8. The bottom end of the rotating stud 8 is provided with a The limiting mechanism that can squeeze downwards and lock the glass bottle on the rotating disk 11 can place the glass bottle on the rotating disk 11, allowing the glass bottle to rise with the rotating disk 11, and the bottom end of the rotating stud 8 will be inserted into the interior of the glass bottle and squeeze the inner wall of the glass bottle through the limiting mechanism, so that the glass bottle is tightly attached to the rotating disk 11. When the rotating stud 8 rotates and drives the spray assembly 4 to rise and fall, the end of the rotating stud 8 can squeeze the glass bottle and rotate synchronously with the rotating disk 11, so that the rotation of the rotating stud 8 can make the lifting and lowering of the spray assembly 4 and the rotation of the glass bottle occur synchronously, and the spray assembly 4 is used to evenly spray the rotating glass bottle below.

[0036] The spraying assembly 4 includes an internal threaded barrel 401, a mounting seat 402 and a glaze spraying head 403. The internal threaded barrel 401 is threadedly arranged on the rotating stud 8, the mounting seat 402 is arranged on the outside of the internal threaded barrel 401, and the guide rod at the bottom end of the mounting top seat 6 movably penetrates the mounting seat 402 to limit the rotation of the mounting seat 402 and the internal threaded barrel 401, so that when the rotating stud 8 rotates, it can drive the internal threaded barrel 401 and the mounting seat 402 to rise and fall. The glaze spraying head 403 is arranged at the edge of the mounting seat 402, and the glaze spraying head 403 is connected to the feeding assembly 3 through a pipe. The glaze spraying head 403 is inclined and faces the direction of the bottom end of the rotating stud 8.

[0037] The mounting seat 402 is a circular base, and a frame for mounting multiple glaze spray heads 403 is arranged at the edge of the mounting seat 402. Multiple glaze spray heads 403 are arranged in a group around the edge of the mounting seat 402, and multiple glaze spray heads 403 are connected to the feeding assembly 3 through different pipes. The length of the connecting pipe is greater than the distance between the bottom end of the rotating stud 8 and the feeding assembly 3. The distance between the nozzles of the multiple glaze spray heads 403 and the limiting mechanism at the bottom end of the rotating stud 8 decreases successively, so that the multiple glaze spray heads 403 form a multi-layered spraying surface.

[0038] The lifting frame 10 includes a connecting frame 1001, a chassis 1002 and a baffle plate 1003. The chassis 1002 is in contact with the inner bottom wall of the transport trolley 5, and the top surface of the chassis 1002 is opposite to the limiting mechanism at the bottom end of the rotating stud 8. One end of the connecting frame 1001 is connected to the lifting end of the lifting cylinder 9, and the other end is connected to the chassis 1002. The rotating disk 11 is arranged on the chassis 1002. The baffle plate 1003 is arranged at the connection between the connecting frame 1001 and the lifting end of the lifting cylinder 9. The baffle plate 1003 can be used to block the lifting end of the lifting cylinder 9 to prevent the colored glaze from being stained on the lifting end of the lifting cylinder 9 during the colored glaze spraying process, thereby affecting the operation of the lifting cylinder 9.

[0039] The rotating disk 11 includes a rotating base 1101 and a placement disk 1102. The rotating base 1101 is arranged on the bottom plate 1002. The placement disk 1102 is rotatably mounted at the center of the top surface of the rotating base 1101. The top surface of the placement disk 1102 is provided with an inner groove for placing glass bottles.

[0040] In this embodiment, when in use, the glass bottle is first placed on the rotating disk 11, and is transported to the spray chamber 1 by the transport trolley 5 and the conveying track 2, and the stop mechanism inside the spray chamber 1 stops the transport trolley 5, so that the lifting mechanism inside the transport trolley 5 and the glass bottle on the rotating disk 11 are located directly below the driving mechanism. At this time, the lifting cylinder 9 can be started to drive the lifting frame 10 and the rotating disk 11 to rise vertically, and the glass bottle on the rotating disk 11 will rise synchronously and approach the bottom end of the rotating stud 8, so that the limiting mechanism at the bottom end of the rotating stud 8 is inserted into the glass bottle and connected with the glass bottle through the limiting mechanism, and at the same time squeezes and locks the glass bottle on the rotating disk 11, so that the rotating stud 8 can drive the glass bottle and the rotating disk 11 to rotate synchronously, at this time, start the driving motor 7 to drive the rotating stud 8 to rotate, the glass bottle and the rotating disk 11 rotate synchronously with the rotating stud 8, and the rotating stud 8 will also drive the internal threaded tube 401 and the mounting seat 402 to move downward along the rotating stud 8. At this time, the multiple colored glaze spray heads 403 at the edge of the mounting seat 402 will form multiple levels of spraying surfaces on the outside of the glass bottle. As the colored glaze spray heads 403 move downward, the multiple colored glaze spray heads 403 can be used to form a circulating and multi-level colored glaze spraying from top to bottom on the outside of the rotating glass bottle, thereby completing the uniform spraying of the glass bottle.

[0041] like Figure 1-9 As shown, this embodiment is basically the same as the first embodiment. Preferably, in order to avoid the influence of the peripheral clamping structure on the glaze spraying of the glass bottle and increase the spraying efficiency, a limiting mechanism is provided here, including a base 12, a bottoming slide 13 and a side pressure frame 14. The base 12 is arranged at the bottom end of the rotating stud 8, and the bottoming slide 13 is movably inserted at the bottom end of the base 12 in the vertical direction. The end of the base 12 is hollow, and a plurality of through grooves are provided on the side wall of the base 12. A plurality of side pressure frames 14 are grouped together and are rotatably installed in the plurality of through grooves through shafts. One end of the side pressure frame 14 is located inside the base 12, and the other end is located outside the base 12. The bottoming slide 13 passes through the end of the base 12 to squeeze the end of the side pressure frame 14 located inside the base 12, so that when the bottoming slide 13 moves up, When the bottoming slide 13 slides up, it will squeeze one side of the side pressure frame 14, so that the side pressure frame 14 rotates around the installed shaft body, and the other end of the side pressure frame 14 rotates and squeezes the inner wall of the glass bottle, forming a tight connection between the rotating stud 8 and the inner wall and bottom wall of the glass bottle. Multiple side pressure frames 14 squeeze the inner wall of the glass bottle in multiple directions, which can force the glass bottle to align with the bottom end of the rotating stud 8 and maintain the same axis. At this time, the rotation of the rotating stud 8 will drive the glass bottle to rotate.

[0042] The bottoming slide 13 includes a limit frame and a rubber pad arranged at the bottom end of the limit frame. The limit frame part of the bottoming slide 13 is movably inserted in the vertical direction at the bottom end of the base 12. Multiple side pressure frames 14 are provided with square pads at one end away from the base 12, and the square pads are also made of rubber. The friction between the rotating stud 8 and the glass bottle is increased by the square pads and the rubber pads.

[0043] The base 12 includes a hollow cylinder connected to the bottom end of the rotating stud 8 and an insert block arranged at the bottom end of the hollow cylinder. The edge of the insert block portion of the base 12 is arc-shaped, so that when the glass bottle rises with the lifting frame 10 and the rotating disk 11, if the glass bottle mouth contacts the arc surface at the edge of the insert block portion, it will guide the glass bottle to move, allowing the insert block portion to be inserted into the glass bottle mouth, helping the limiting mechanism to be inserted into the glass bottle mouth, and also paving the way for the side pressure frame 14 and the rotating stud 8 above the base 12, so as to facilitate the subsequent alignment of the glass bottle mouth with the limiting mechanism at the bottom end of the rotating stud 8.

[0044] In this embodiment, when the glass bottle rises with the lifting frame 10 and the rotating disk 11, if the mouth of the glass bottle is not aligned with the bottom end of the rotating stud 8, the mouth of the glass bottle will contact the arc surface at the edge of the plug part during the rising process. Through the guiding effect of the arc surface, the mouth of the glass bottle will squeeze the arc surface and move, allowing the plug part of the bottom platform 12 to be inserted into the mouth of the glass bottle, helping the limiting mechanism to be inserted into the mouth of the glass bottle, and the glass bottle continues to move up. At this time, the rubber pad part of the bottoming slide 13 will first squeeze the bottom of the glass bottle, and the bottoming slide 13 will slide up. When the bottoming slide 13 slides up, it will squeeze one side of the side pressure frame 14, so that the side pressure frame 14 rotates around the installed shaft body, allowing the other end of the side pressure frame 14 to rotate The square pad is squeezed to fit the inner wall of the glass bottle. Multiple side pressure frames 14 squeeze the inner wall of the glass bottle in multiple directions, which can force the glass bottle to align with the bottom end of the rotating stud 8 and maintain the same axis. The square pad and the rubber pad squeeze the inner wall and the bottom wall of the glass bottle, thereby increasing the friction between the limiting mechanism at the bottom end of the rotating stud 8 and the glass bottle, thereby forming a tight connection between the rotating stud 8 and the inner wall and the bottom wall of the glass bottle. At this time, the rotation of the rotating stud 8 will drive the glass bottle and the rotating disk 11 to rotate, thereby forming a structure fixed in position by the inside of the glass bottle. When the position of the glass bottle is limited, there is no need to use a clamping mechanism on the periphery of the glass bottle, thereby avoiding spraying blanks on the outer wall of the glass bottle due to the clamping mechanism.

[0045] A method for spraying a glass bottle using a glass bottle colored glaze spraying device, the method steps are as follows:

[0046] S1, first place the glass bottle on the rotating disk 11, and transport it to the spray room 1 by using the transport trolley 5 and the conveying track 2, and use the stop mechanism to stop the transport trolley 5, so that the transport trolley 5 is located directly below the driving mechanism. At this time, the lifting cylinder 9 can be used to drive the lifting frame 10 and the rotating disk 11 to rise, so that the glass bottle on the rotating disk 11 rises synchronously, and the limiting mechanism at the bottom of the rotating stud 8 is inserted into the glass bottle. When the glass bottle rises to the bottom of the rotating stud 8, the glass bottle is squeezed, and the glass bottle and the rotating stud 8 are connected through the limiting mechanism. At this time, the driving motor 7 is started to drive the rotating stud 8 to rotate, and the glass bottle and the rotating disk 11 will rotate synchronously;

[0047] S2, when the glass bottle on the rotating disk 11 rises, the limiting mechanism at the bottom end of the rotating stud 8 is inserted into the glass bottle, and the bottoming slide 13 will first squeeze the bottom of the glass bottle, so that the bottoming slide 13 slides up vertically, and the sliding of the bottoming slide 13 will squeeze one end of the side pressing frame 14, so that the side pressing frame 14 rotates around the installed shaft body, and the other end of the side pressing frame 14 rotates and squeezes the inner wall of the glass bottle. Multiple side pressing frames 14 squeeze the inner wall of the glass bottle in multiple directions, which can force the glass bottle to align with the bottom end of the rotating stud 8 and keep the same The bottom end of the bottoming slide 13 is tightly pressed against the bottom wall of the inner side of the glass bottle, so that the top end of the bottoming slide 13 is tightly pressed against one end of the side pressing frame 14, and the other end of the side pressing frame 14 is tightly fitted against the inner wall of the glass bottle, so that the limiting mechanism at the bottom end of the rotating stud 8 is tightly connected with the inner wall and the bottom wall of the glass bottle. At this time, the rotation of the rotating stud 8 will drive the glass bottle to rotate synchronously. Due to the connection between the glass bottle and the rotating disk 11 and the rotation characteristics of the rotating disk 11 itself, the rotating disk 11 will also rotate synchronously with the rotating stud 8 and the glass bottle.

[0048] S3, during spraying, when the rotating stud 8, the glass bottle and the rotating disk 11 rotate synchronously, the internal threaded tube 401 and the mounting seat 402 will move downward with the rotation of the rotating stud 8, driving the glaze spraying head 403 to move downward synchronously. At this time, the glaze spraying head 403 will be used to spray the rotating glass bottle with glaze. The glaze spraying head 403 moves downward synchronously with the glass bottle, and the glaze spraying is circulated and carried out from top to bottom, forming a uniform spraying of the glass bottle.

[0049] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
