Description

Technical Field

[0001] The invention relates to the technical field of glass spraying, and in particular to a spraying device for producing glass and a spraying process thereof. Background Art

[0002] Glass cup spraying is divided into internal spraying and external spraying. The internal and external spraying improve the performance of the glass cup differently. Among them, the external spraying of the glass cup can be used for a variety of purposes, including improving aesthetics, increasing functionality, protecting the glass surface, etc., while the internal spraying of the glass cup is mainly used for anti-fouling, easy cleaning and antibacterial. In people's daily life, glass cups are involved in various industries, and the purposes of spraying in different industries are different. Among them, the spherical glass cups used in kitchens and restaurants require extremely high hygiene levels to ensure people's food health. Therefore, during preparation, it is necessary to spray an antibacterial coating on the inner wall of the spherical glass cup to reduce the growth of bacteria. However, when the existing spherical glass cup spraying device sprays the spherical glass cup, the nozzle enters the inside of the spherical glass cup and sprays directly from bottom to top, resulting in different spraying distances of the nozzle on the inner wall of the spherical glass cup, resulting in uneven distribution of the antibacterial coating in the spherical glass cup, and low antibacterial performance in the spherical glass cup.

[0049] 2. By resetting the nozzle along the rotating shell and driving the sliding column to deviate as a whole, the distance between the nozzle and the inner wall of the glass cup outlet is extended to ensure that the spraying distance of the inner wall of the glass cup remains consistent, avoiding the small radius of the inner wall at the glass cup outlet, resulting in a smaller spraying distance of the nozzle and reduced uniformity of the glass cup spraying.

[0050] 3. When the nozzle is used to spray at different radii of the glass, the rotation speed of the glass is automatically adjusted to further improve the uniformity of the nozzle spraying on the inner wall of the glass.

[0051] 4. By increasing the support strength of the airbag at the handle of the glass, the support force on the glass is increased, thereby offsetting the centrifugal force of the handle of the glass, improving the stability of the glass when it rotates, and improving the uniformity of the glass spraying.

DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0062] When the existing spherical glass cup spraying device sprays the spherical glass cup, the nozzle enters the spherical glass cup and sprays directly from bottom to top, resulting in different spraying distances between the nozzle and the inner wall of the spherical glass cup, thereby making the antibacterial coating in the spherical glass cup unevenly distributed and the antibacterial performance in the spherical glass cup low.

[0063] A spraying device for glass production, such as Figure 1-Figure 5As shown, it includes: a base 1; a sliding plate 2, which is slidably connected to the base 1, and the sliding plate 2 is slidably connected to a sliding column 3; a rotating shell 4, which is rotatably connected to the sliding column 3; a nozzle 5, which is slidably connected in the rotating shell 4, and the sliding column 3 is provided with an electric swivel 6, and the driving part of the electric swivel 6 is fixedly connected to the rotating shell 4; a first elastic element 7, which is arranged between the rotating shell 4 and the nozzle 5; a limit block 8, which is rotatably connected to the sliding column 3, and the limit block 8 is pressed and matched with the nozzle 5; a driving component, which is arranged on the base 1, and is used to drive the sliding plate 2 to move up and down; A rotation speed regulating component is arranged on the base 1, and is used to drive the glass cup to rotate; a distance adjusting component is arranged on the sliding plate 2, and is used to drive the sliding column 3 to slide along the sliding plate 2; the limit block 8 is provided with a first curved surface portion 801 and a second curved surface portion 802 which are connected to each other, and the cross-sections of the first curved surface portion 801 and the second curved surface portion 802 are both arcs, and the center of the circle corresponding to the arc of the cross-section of the first curved surface portion 801 is not passed through by the rotation axis center line of the rotating shell 4, and the center of the circle corresponding to the arc of the cross-section of the second curved surface portion 802 is passed through by the rotation axis center line of the rotating shell 4.

[0064] In the above scheme, a control module is provided on the base 1, and the control module is used to assist the staff in setting parameters and turning on or off the operation of the device. The nozzle 5 is electrically connected to the control module to control the opening or closing of the nozzle 5. The nozzle 5 is an electrostatic nozzle, and the paint particles are charged by electrostatic action to improve the adhesion of the paint. The nozzle 5 is connected to the external injection device through a hose for continuous feeding. The electric swivel 6 is electrically connected to the control module to open or close the electric swivel 6. The first elastic element 7 is a spring for driving the reset of the nozzle 5. The drive assembly is a simple vertical drive mechanism. The present invention uses the cooperation of the motor and the lead screw to realize the up and down movement of the sliding plate 2, which has the characteristics of high stability. The end of the first curved surface 801 of the limit block 8 away from the second curved surface 802 is initially in contact with the nozzle 5. When the nozzle 5 slides from the initial position along the first curved surface 801 to the end close to the second curved surface 802, the nozzle 5 gradually slides outward along the rotating shell 4 to keep the spraying distance consistent when the nozzle 5 sprays the plane at the bottom of the glass.

[0065] Specifically, Figure 1 and Figure 2 As shown, the rotation speed regulation component includes: a servo motor 201, fixedly connected to the base 1; a first gear 202, fixedly connected to the output shaft of the servo motor 201; a fixed sleeve 203, rotatably connected to the base 1, the fixed sleeve 203 is fixedly connected with a gear ring, and the gear ring of the fixed sleeve 203 is meshed with the first gear 202; a fixed component, arranged on the fixed sleeve 203, is used to fix the glass.

[0066] In the above scheme, the servo motor 201 is electrically connected to the control module for controlling the opening or closing of the servo motor 201. The outside of the first gear 202 and the toothed ring on the fixed sleeve 203 are polished to make the outside smoother, which is convenient for staff to clean and avoid coating particles adhering to the outside of the first gear 202 and causing jamming.

[0067] Specifically, Figure 3 and Figure 4 As shown, the distance adjustment component includes: an electric push rod 301, which is fixedly connected to the sliding plate 2, and the telescopic end of the electric push rod 301 is fixedly connected to the sliding column 3; a second gear 302, which is rotatably connected to the sliding column 3, and the second gear 302 and the limit block 8 are matched through a belt and a pulley transmission; a rack frame 303, which is fixedly connected to the sliding plate 2, and the second gear 302 is meshed with the rack frame 303.

[0068] In the above scheme, the electric push rod 301 is electrically connected to the control module for controlling the opening or closing of the electric push rod 301. The electric push rod 301 is sealed to prevent coating particles from entering its interior and causing damage to the electric push rod 301. The exterior of the second gear 302 and the rack rack 303 are polished to facilitate cleaning by the staff. Belts are fixedly connected to the second gear 302 and the limit block 8, and a belt is wound between the two belts to rotate the limit block 8.

[0069] Specifically, Figure 6 As shown, the fixing assembly includes: a rotating disk 401, which is rotatably connected to the fixing sleeve 203 and is rotatably connected to the base 1; a plurality of fixing frames 402, which are all slidably connected between the rotating disk 401 and the fixing sleeve 203; and a plurality of fitting airbags 403, which are the same in number as the fixing frames 402 and are respectively fixedly connected to adjacent fixing frames 402.

[0070] In the above scheme, the rotating disk 401 is provided with a plurality of circumferentially evenly spaced inclined grooves, the number of which can be changed, the fixed sleeve 203 is provided with circumferentially evenly spaced straight grooves, the number of straight grooves, inclined grooves and fixed frames 402 is the same, the fixed frames 402 are located between the straight grooves and the adjacent inclined grooves on the fixed sleeve 203, and a locking device is provided on the rotating disk 401 to prevent the rotating disk 401 from rotating relative to the fixed sleeve 203 while driving the glass to rotate, thereby reducing the fixing strength of the glass, and the outer portion of the fitting airbag 403 is an arc-shaped surface, which is used to fit the outer contour of the glass and improve the fastening stability of the glass.

[0071] When the staff needs to spray the inside of the spherical glass cup, the staff puts the glass cup on the rotating disk 401, and then rotates the rotating disk 401, so that the rotating disk 401 drives a plurality of fixing frames 402 thereon to slide synchronously inward along the fixing sleeve 203, so that the plurality of fixing frames 402 drive the fitting airbags 403 thereon to flexibly clamp the outside of the glass cup, and then stops rotating the rotating disk 401, at which time the glass cup is fixed.

[0072] When the glass is fixed, the staff drives the sliding plate 2 to slide downward along the base 1 through the driving component, so that the sliding plate 2 drives the sliding column 3 thereon to move downward synchronously, and the sliding column 3 drives the rotating shell 4 and the nozzle 5 inside it to move downward synchronously, until the rotation axis of the rotating shell 4 passes through the center of the glass, the driving component is stopped to stop the sliding plate 2 from sliding downward, and then the servo motor 201 is turned on, so that the output shaft of the servo motor 201 drives the first gear 202 to rotate, and the first gear 202 drives the fixed sleeve 203 to rotate synchronously through the gear ring, and the fixed sleeve 203 drives several fixed frames 402 thereon to rotate synchronously, thereby driving the glass to rotate synchronously, and then the electric swivel 6 and the nozzle 5 are turned on, so that the nozzle 5 starts to spray the center of the circle at the bottom of the glass, and at the same time, the electric swivel 6 drives the rotating shell 4 to rotate, and the rotating shell 4 drives the internal nozzle 5 to rotate synchronously, and the nozzle 5 starts to slide in contact with the limit block 8. Initially, the nozzle 5 slides along the limit block 8. The first curved portion 801 of the stop block 8 slides to spray the bottom plane of the glass. During this process, the stop block 8 squeezes the nozzle 5, causing the nozzle 5 to slide along the rotating shell 4, and compresses the first elastic element 7 at the same time, until the nozzle 5 slides along the first curved portion 801 of the stop block 8 to the docking point with the second curved portion 802. During this process, the distance between the nozzle 5 and the bottom of the glass is always consistent, thereby improving the uniformity of the spraying inside the glass. Then the nozzle 5 continues to rotate to spray the inner wall of the glass. At this time, the nozzle 5 slides along the second curved portion 802 of the stop block 8 until the nozzle 5 slides to the outlet of the glass, and then the spraying of the nozzle 5 is stopped. When spraying from the bottom of the glass to the outlet, the nozzle 5 first slides along the rotating shell 4, and then the sliding amplitude of the nozzle 5 and the rotating shell 4 is maintained until the spraying reaches the outlet, so that the distance between the nozzle 5 and the inner wall of the glass is always consistent, thereby improving the uniformity of the spraying of the inner wall of the glass by the nozzle 5.

[0073] When the spray head 5 sprays to the outlet of the glass, the spray head 5 stops spraying, and then the electric swivel 6 drives the spray head 5 to rotate in the opposite direction to the horizontal spraying state, and at the same time, the electric push rod 301 is turned on, so that the electric push rod 301 drives the sliding column 3 to slide along the sliding plate 2, and the sliding column 3 drives the second gear 302 and the bottom spray head 5 to slide horizontally synchronously, and the second gear 302 rotates along the rack 303, and the second gear 302 drives the limit block 8 to rotate synchronously through the belt and the pulley, so that the contact part between the horizontal spray head 5 and the limit block 8 slides from the second curved surface 802 to the end of the first curved surface 801 away from the second curved surface 802, and at this time, the first elastic element 7 drives the spray head 5 to slide inward along the rotating shell 4 to the initial The spraying distance between the nozzle 5 and the inner wall of the glass outlet is kept constant, the electric push rod 301 is turned off, and the driving assembly is turned on to drive the sliding plate 2 to move upward. When the nozzle 5 moves upward to the junction of the spherical inner wall of the glass and the inner wall of the outlet, the nozzle 5 is turned on again to spray the inner wall of the glass outlet. This is done until the nozzle 5 has completed spraying the glass. The nozzle 5 is reset along the rotating shell 4 and the sliding column 3 is driven to shift as a whole to extend the distance between the nozzle 5 and the inner wall of the glass outlet. This ensures that the spraying distance of the inner wall of the glass remains consistent, thereby avoiding a small radius of the inner wall at the glass outlet, which results in a smaller spraying distance of the nozzle 5 and reduced uniformity of spraying of the glass.

[0074] When the glass is sprayed, the nozzle 5 is closed, and the driving assembly continues to drive the sliding plate 2 to move upward to the initial position. The driving assembly is closed and the electric push rod 301 is turned on, so that the telescopic end of the electric push rod 301 drives the sliding column 3 to slide to the initial state. At the same time, the second gear 302 is reset and rotated along the rack frame 303, so that the limit block 8 is reset to the initial position, and the electric swivel 6 is turned on, so that the electric swivel 6 drives the rotating shell 4 to reset to the initial state, and then the staff resets the rotating disk 401 to reset and slide the several fixed frames 402. At this time, the several fitting airbags 403 release the clamping of the glass, and then the staff removes the glass, places a new glass to be sprayed, and repeats the above steps.

[0075] In a further embodiment, Figure 2 , Figure 7 and Figure 8 As shown, it also includes: a centrifugal component, which is arranged on the base 1 and is used to detect the rotation speed of the fixed sleeve 203. The centrifugal component includes: a centrifugal disk 501, which is rotatably connected to the base 1; a third gear 502, which is fixedly connected to the centrifugal disk 501, and the fixed sleeve 203 is meshed with the third gear 502 through a gear ring; a plurality of extrusion blocks 503, which are all slidably connected to the centrifugal disk 501, and a second elastic element 504 is arranged between the extrusion block 503 and the centrifugal disk 501; a force-applying component, which is arranged on the base 1 and is used to transmit the centrifugal force of the extrusion block 503.

[0076] In the above scheme, the exterior of the third gear 502 is polished for easy cleaning, the number and weight of the extrusion blocks 503 can be adjusted according to actual conditions, an arc-shaped surface is provided at the bottom of the extrusion block 503, and the second elastic element 504 is a spring, which has the same number as the extrusion blocks 503 and is used to drive the adjacent extrusion blocks 503 to reset.

[0077] Specifically, Figure 7 and Figure 8 As shown, the force-applying assembly includes: an air cylinder 505, fixedly connected to the base 1; a piston shaft 506, sealingly and slidably connected in the air cylinder 505, and the two cooperate to form a first closed cavity; a lower pressure plate 507, slidably connected to the piston shaft 506, and a third elastic element 508 is arranged between the two; a support assembly, arranged on the base 1, for increasing the local support strength of the glass cup.

[0078] In the above scheme, a heat-resistant coating is provided on the outside of the gas cylinder 505 to isolate the influence of the external temperature on the gas in the first closed cavity. An inverted truncated cone-shaped groove is provided on the upper plane of the lower pressure plate 507. The arc surface of the extrusion block 503 fits with the inner wall of the inverted truncated cone-shaped groove to enable the extrusion block 503 to squeeze the lower pressure plate 507 to slide downward. The third elastic element 508 is a spring, which is used to drive the lower pressure plate 507 to reset.

[0079] Specifically, Figure 1 , Figure 2 and Figure 7 As shown, the support assembly includes: a fixed ring 509, fixedly connected to the base 1, and the central axis of the fixed ring 509 is colinear with the central axis of the fixed sleeve 203; an inner ring 510, sealed and rotatably connected in the fixed ring 509, the two cooperate to form a second closed cavity, a flexible tube is fixedly connected between the air cylinder 505 and the fixed ring 509, the flexible tube is used to connect the first closed cavity and the second closed cavity, the inner ring 510 is sealed and slidably connected to the upper part of the fixed frame 402 of the fixed sleeve 203, the second closed cavity is connected to the adjacent fitting airbag 403 on the above-mentioned fixing frame 402; the fixed sleeve 203 is divided into two sides, and the fitting airbag 403 connected to the second closed cavity is located on the same side of the rotating disk 401.

[0080] In the above scheme, steel wire is mixed inside the flexible tube, which has a certain structural strength to prevent the flexible tube from expanding and reduce the conduction of the force. The number of the fixing frames 402 is at least three, and at least two adjacent fitting airbags 403 are connected to the second closed cavity. When placed, the handle of the glass cup is placed in the middle of the two fitting airbags 403 connected to the second closed cavity.

[0081] When spraying the inner wall of the glass, since the radii of different parts of the glass are inconsistent, when the nozzle 5 sprays from the bottom center of the glass to the maximum radius of the glass, the rotation speed of the servo motor 201 output shaft gradually decreases, thereby causing the rotation speed of the glass to decrease synchronously. When the nozzle 5 sprays from the maximum radius of the glass upward to the outlet of the glass, the rotation speed of the servo motor 201 output shaft gradually increases. When the nozzle 5 sprays the inner wall of the outlet of the glass, the rotation speed of the servo motor 201 output shaft will decrease to the required specific value. When the nozzle 5 sprays different radii of the glass, the rotation speed of the glass is automatically adjusted to further improve the uniformity of the spraying of the inner wall of the glass by the nozzle 5.

[0082] Since the glass has a handle, when it is rotated for spraying, the weight of the handle of the glass is greater than other positions, and the centrifugal force on the handle of the glass is greater, which causes the glass to easily deflect and tilt when it is rotated for spraying, resulting in uneven spraying on the inner wall of the glass. When the staff fixes the glass (here, the three fixing frames 402 are used as the standard, that is, there are two fitting air bags 403 connected to the second closed cavity), the staff places the handle of the glass in the middle between the two fitting air bags 403 connected to the second closed cavity, and then rotates the rotating disk 401 to fix the glass, and starts spraying the glass. When the output shaft of the servo motor 201 rotates through the first gear 202 and the gear ring driving the fixed sleeve 203, the fixed sleeve 203 will drive the third gear 502 to rotate through the gear ring thereon, and the third gear 502 drives the centrifugal disk 501 to rotate, and the centrifugal disk 501 drives the multiple extrusion blocks 503 thereon to rotate synchronously, so that the multiple extrusion blocks 503 slide outward along the centrifugal disk 501 under the centrifugal force. , the second elastic element 504 is compressed, and at the same time, a plurality of extrusion blocks 503 jointly squeeze the lower pressure plate 507, so that the lower pressure plate 507 slides downward along the piston shaft 506, and the third elastic element 508 is compressed to apply a force to the piston shaft 506, and the force is transmitted to the gas in the two fitted air bags 403 through the piston shaft 506, the gas in the first closed cavity, the gas in the flexible tube, and the gas in the second closed cavity. At this time, the gas in the two fitted air bags 403 is affected by the force, and the supporting force on the glass cup is increased, thereby offsetting the centrifugal force of the glass handle, improving the stability of the glass when rotating, and improving the uniformity of the glass spraying. At the same time, since the rotation speed of the centrifugal disk 501 is matched with the rotation speed of the fixed sleeve 203, that is, the rotation speed of the glass increases or decreases, the rotation speed of the centrifugal disk 501 is synchronously changed, so that the centrifugal force of the glass handle is offset by the adaptive change of the rotation speed of the glass, further improving the stability of the glass, and improving the uniformity of the spraying of the inner wall of the glass.

[0083] In a further embodiment, Figure 1-Figure 8As shown, a spraying process for producing glass cups, using the above-mentioned spraying equipment for producing glass cups, includes the following steps:

[0084] Step S1: placing the glass to be sprayed, and driving the rotating disk 401 to rotate, so that the rotating disk 401 drives the plurality of fixing frames 402 to slide along the fixing sleeve 203, and the plurality of fitting airbags 403 flexibly clamp the outside of the glass to complete the fixing of the glass;

[0085] Step S2: Control the nozzle 5 to enter the interior of the glass, so that the axis of rotation of the rotating shell 4 passes through the center of the glass, and then the nozzle 5 sprays the inner wall of the glass at the same spraying distance, and at the same time, the servo motor 201 is turned on to drive the glass to rotate, and the rotation speed is adaptively adjusted according to the radius of the spraying position of the glass, so as to complete the spraying of the bottom and inner wall of the glass;

[0086] Step S3: After the bottom and inner wall of the glass are sprayed, the nozzle 5 is raised to the outlet of the glass, and the nozzle 5 is reset and slid along the rotating shell 4, and the sliding column 3 drives the nozzle 5 to deviate to the same distance as when spraying the inner wall of the glass, and then the inner wall of the outlet of the glass is sprayed. At the same time, the servo motor 201 adjusts the rotation speed according to the radius of the outlet of the glass, and this is done until the spraying of the outlet of the glass is completed;

[0087] Step S4: When spraying at different radii on the inner wall of the glass, the rotation speed of the glass is different. At this time, the support strength of the airbag 403 at the handle of the glass to the inner wall of the glass is adaptively changed according to the rotation speed of the glass, and this is done until the spraying of the glass is completed and the glass is removed.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
