Description

Technical Field

[0001] This invention belongs to the field of ceramic glazing technology, specifically referring to an automatic ceramic glazing device. Background Technology

[0002] The "immersion glazing method" is one of the most common methods for glazing ceramics. The specific steps involve immersing the ceramic blank in glaze for a period of time and then removing it; after that, it is first dried and then fired. The purpose of glazing ceramics is mainly to seal the micropores of the pottery itself. Therefore, whether to glaze the inner or outer layer depends mainly on the function. For decorative bottles and jars that do not hold liquids, only the outer layer and the mouth of the bottle need to be glazed.

[0003] The thickness of the glaze layer in the "immersion glazing method" is related to the immersion time in the glaze liquid. Therefore, automated glazing equipment can effectively ensure product consistency. In addition, current glazing devices still need to address the following issues:

[0004] A: How to solve the problem that the traditional clamping position cannot be coated with glaze;

[0005] B: How to overcome the contradiction of glazing the inner wall of the bottle mouth but not glazing the inner wall of the bottle body and bottom. Summary of the Invention

[0006] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an automatic ceramic glazing device. Since the inner wall of the bottle does not require glazing, this solution uses an airbag that expands from the inside to hold the ceramic bottle in place. However, under normal circumstances, the airbag needs to be connected to an external air source through a pipe to control the air pressure. But since the pressurizing component needs to rotate, the air pipe will become entangled with the cable of the rotating motor when it rotates. To overcome this problem, this invention proposes a closed pressurizing component, which automatically controls the internal air pressure of the pressurizing component through the lifting motion inherent in the glazing process.

[0007] Furthermore, in order to maintain the internal air pressure of the pressurization component after picking up the ceramic bottle, this solution also proposes an automatic high-pressure holding mechanism. By changing the force direction of the ratchet rack, the engagement and disengagement of the ratchet assembly are automatically controlled, thereby limiting the relative movement of the outer sleeve and the inner sleeve.

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes an automatic ceramic glazing device, including a pneumatic internal support fixing mechanism, an automatic high pressure holding mechanism, and a lifting and swinging mechanism. The pneumatic internal support fixing mechanism includes a bottle body rotating component, a pressurizing component, and a resetting component. The bottle body rotating component is rotatably disposed in the lifting and swinging mechanism, the pressurizing component is disposed on the bottle body rotating component, and the resetting component is disposed in the pressurizing component.

[0009] The automatic high-pressure holding mechanism includes a ratchet assembly and an automatic unlocking assembly. The ratchet assembly is located in the pressurization assembly, and the automatic unlocking assembly is located in the ratchet assembly.

[0010] The ratchet assembly includes a ratchet ring, a rack sliding box, and a ratchet rack. The ratchet ring is fixed to the top of the inner wall of the outer sleeve. The inner sleeve has a through groove, and the rack sliding box is fixed to the through groove. The ratchet rack is engaged and slidably disposed in the rack sliding box, and the teeth of the ratchet ring and the ratchet rack are matched with each other.

[0011] The ratchet rack controls its extension and retraction based on changes in internal air pressure, thereby automatically changing the one-way locking or unlocking mode of the ratchet assembly. It can automatically maintain the pressure inside the chamber and the retracted state of the inner sleeve when clamping ceramic bottles, and allow the inner sleeve to extend and reset when disassembling ceramic bottles.

[0012] Furthermore, the automatic unlocking component includes a partition and a tension spring. The partition is fixed to the middle position of the rack and pinion sliding box, and the tension spring is disposed between the partition and the ratchet rack.

[0013] Preferably, the reset assembly includes a sliding guide plate and a reset spring. The sliding guide plate is fixed to the top of the outer sleeve. The rack sliding box is provided with an arc-shaped stop, which slides in contact with the sliding guide plate. The reset spring is located between the inner sleeve and the outer sleeve.

[0014] The return spring ensures that the two ratchet racks always tend to retract, so that when the pressure in the chamber decreases, the ratchet assembly is automatically unlocked by the retraction of the ratchet racks.

[0015] Furthermore, the pressurization assembly includes an outer sleeve, an airbag, and an inner sleeve. The outer sleeve is provided with air windows evenly distributed in a ring. The airbag is fitted outside the air windows and communicates with the outer sleeve. The inner sleeve is engaged and slidably disposed in the outer sleeve. The inner sleeve is provided with a one-way valve that can be actively opened.

[0016] Preferably, when the inner sleeve slides in the outer sleeve, it can increase the air pressure inside the closed chamber. When the air pressure increases, it can not only expand the airbag to fix the ceramic bottle from the inside, but also push the ratchet rack to extend, so that it can form a one-way transmission engagement with the ratchet ring.

[0017] As a further preferred embodiment of the present invention, the bottle body rotating assembly includes a rotating bracket and a rotating motor, the rotating motor being fixedly connected to the rotating bracket, the inner sleeve being rotatably disposed in the rotating bracket, and the output shaft of the rotating motor being connected to the inner sleeve.

[0018] The rotating motor can continuously and slowly rotate the ceramic bottle to achieve uniform glazing.

[0019] Furthermore, the lifting and swinging mechanism includes a swinging component and a lifting component. The swinging component is disposed on the lifting component, and the rotating bracket is symmetrically provided with swinging shafts. The rotating bracket is rotatably disposed in the swinging component through the swinging shafts.

[0020] Preferably, the swing assembly includes a swing fork and a swing motor, the swing shaft is rotatably disposed in the swing fork, the swing motor is disposed on one side of the swing fork, and the output shaft of the swing motor is connected to the swing shaft.

[0021] By using a swing motor, the tilt angle of the ceramic bottle can be changed, bringing the center of the flat bottom and the flange of the bottle mouth to the same horizontal level. This not only allows the inner wall of the bottle mouth to be glazed but not the inner wall of the bottle body, thus meeting the technical requirements of this working condition, but also reduces the degree of unevenness in the glaze thickness of the flat bottom.

[0022] As a further preferred embodiment of the present invention, the lifting assembly includes a guide telescopic rod, a telescopic push rod, and a sliding plate. The guide telescopic rod is symmetrically arranged between the swing fork and the sliding plate, and the telescopic push rod is arranged between the swing fork and the sliding plate.

[0023] The telescopic push rod's extension speed can be matched with the rotation speed of the rotating motor to achieve the technical effect of the ceramic bottle being evenly immersed in glaze and then immediately leaving the glaze liquid.

[0024] As a further preferred embodiment of the present invention, the slide plate is provided with a slider, which is slidably disposed on an external guide rail, and the bottom of the outer sleeve is provided with a rubber ring that contacts the ceramic bottle.

[0025] The beneficial effects achieved by the present invention using the above structure are as follows:

[0026] (1) The ratchet controls its extension and retraction according to the change of internal air pressure, thereby automatically changing the one-way locking or unlocking mode of the ratchet assembly. It can automatically maintain the pressure in the chamber and the retraction state of the inner sleeve when clamping the ceramic bottle, and allow the inner sleeve to extend and reset when disassembling the ceramic bottle.

[0027] (2) The return spring makes the two ratchet racks always have a tendency to retract, so that when the pressure in the chamber decreases, the ratchet assembly is automatically unlocked by the retraction of the ratchet racks.

[0028] (3) When the inner sleeve slides in the outer sleeve, it can increase the air pressure inside the closed chamber. When the air pressure increases, it can not only open the air bag and fix the ceramic bottle from the inside, but also push the ratchet rack out so that it can form a one-way transmission cooperation with the ratchet ring.

[0029] (4) The rotating motor can continuously and slowly rotate the ceramic bottle to achieve uniform glazing.

[0030] (5) The tilt angle of the ceramic bottle can be changed by the swing motor, so that the center position of the flat bottom and the flange of the bottle mouth are at the same level. This not only allows the inner wall of the bottle mouth to be glazed but the inner wall of the bottle body to be unglazed, thus meeting the technical requirements of this working condition, but also reduces the degree of unevenness of the glaze layer thickness on the flat bottom.

[0031] (6) The telescopic push rod’s extension speed can be matched with the rotation speed of the rotating motor to achieve the technical effect of the ceramic bottle being uniformly immersed in glaze and then immediately leaving the glaze liquid. Attached Figure Description

[0044] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] like Figures 1-10 As shown, the present invention proposes an automatic ceramic glazing device, including a pneumatic internal support fixing mechanism 2, an automatic high pressure holding mechanism 3, and a lifting and swinging mechanism 4. The pneumatic internal support fixing mechanism 2 includes a bottle body rotating assembly 5, a pressurizing assembly 6, and a resetting assembly 7. The bottle body rotating assembly 5 is rotatably disposed in the lifting and swinging mechanism 4, the pressurizing assembly 6 is disposed on the bottle body rotating assembly 5, and the resetting assembly 7 is disposed in the pressurizing assembly 6.

[0047] The automatic high-pressure holding mechanism 3 includes a ratchet assembly 19 and an automatic unlocking assembly 20. The ratchet assembly 19 is located in the pressurizing assembly 6, and the automatic unlocking assembly 20 is located in the ratchet assembly 19.

[0048] The ratchet assembly 19 includes a ratchet ring 21, a rack sliding box 22, and a ratchet rack 23. The ratchet ring 21 is fixed to the top of the inner wall of the outer sleeve 10. The inner sleeve 12 is provided with a through groove 18. The rack sliding box 22 is fixed in the through groove 18. The ratchet rack 23 is engaged and slidably disposed in the rack sliding box 22. The teeth of the ratchet ring 21 and the ratchet rack 23 are matched with each other.

[0049] The ratchet 23 controls its extension and retraction according to the change of internal air pressure, thereby automatically changing the one-way locking or unlocking mode of the ratchet assembly 19. It can automatically maintain the pressure in the chamber and the retracted state of the inner sleeve 12 when clamping the ceramic bottle 1, and allow the inner sleeve 12 to extend and reset when disassembling the ceramic bottle 1.

[0050] The automatic unlocking component 20 includes a partition 24 and a tension spring 25. The partition 24 is fixed to the middle position of the rack and pinion sliding box 22, and the tension spring 25 is located between the partition 24 and the ratchet 23.

[0051] The reset assembly 7 includes a sliding guide plate 13 and a reset spring 14. The sliding guide plate 13 is fixed to the top of the outer sleeve 10. The rack sliding box 22 is provided with an arc-shaped stop 26. The arc-shaped stop 26 and the sliding guide plate 13 are in sliding contact. The reset spring 14 is located between the inner sleeve 12 and the outer sleeve 10.

[0052] The reset spring 14 ensures that the two ratchet racks 23 always tend to retract, so that when the pressure in the chamber decreases, the ratchet assembly 19 is automatically unlocked by the retraction of the ratchet racks 23.

[0053] The pressurization assembly 6 includes an outer sleeve 10, an airbag 11, and an inner sleeve 12. Air windows 16 are evenly distributed in a ring on the outer sleeve 10. The airbag 11 is sleeved outside the air windows 16 and communicates with the outer sleeve 10. The inner sleeve 12 is engaged and slidably disposed in the outer sleeve 10. A one-way valve 17 is provided on the inner sleeve 12. The one-way valve 17 can be opened actively.

[0054] When the inner sleeve 12 slides in the outer sleeve 10, it can increase the air pressure inside the closed chamber. When the air pressure increases, it can not only open the airbag 11 to fix the ceramic bottle 1 from the inside, but also push the ratchet 23 to extend, so that it and the ratchet ring 21 form a one-way transmission engagement.

[0055] The bottle body rotating assembly 5 includes a rotating bracket 8 and a rotating motor 9. The rotating motor 9 is fixedly connected to the rotating bracket 8, and the inner sleeve 12 is rotatably disposed in the rotating bracket 8. The output shaft of the rotating motor 9 is connected to the inner sleeve 12.

[0056] The rotating motor 9 can continuously and slowly rotate the ceramic bottle 1 to achieve uniform glazing.

[0057] The lifting and swinging mechanism 4 includes a swinging component 27 and a lifting component 28. The swinging component 27 is mounted on the lifting component 28. The rotating bracket 8 is symmetrically provided with swinging shafts 15. The rotating bracket 8 is rotatably mounted in the swinging component 27 through the swinging shafts 15.

[0058] The swing assembly 27 includes a swing fork 29 and a swing motor 30. The swing shaft 15 is rotatably disposed in the swing fork 29, and the swing motor 30 is disposed on one side of the swing fork 29. The output shaft of the swing motor 30 is connected to the swing shaft 15.

[0059] The tilt angle of the ceramic bottle 1 can be changed by the swing motor 30, so that the center position of the flat bottom and the flange of the bottle mouth are at the same level. This not only allows the inner wall of the bottle mouth to be glazed but the inner wall of the bottle body to remain unglazed, thus meeting the technical requirements of this working condition, but also reduces the degree of unevenness in the glaze thickness of the flat bottom.

[0060] The lifting assembly 28 includes a guide telescopic rod 31, a telescopic push rod 32, and a sliding plate 33. The guide telescopic rod 31 is symmetrically arranged between the swing fork 29 and the sliding plate 33, and the telescopic push rod 32 is arranged between the swing fork 29 and the sliding plate 33.

[0061] The telescopic push rod 32 can be telescopically extended and retracted at a speed that matches the rotational speed of the rotating motor 9, so as to achieve the technical effect of the ceramic bottle 1 being uniformly immersed in glaze and then immediately leaving the glaze liquid.

[0062] The slide plate 33 is equipped with a slider 34, which slides on the outer guide rail. The bottom of the outer sleeve 10 is equipped with a rubber ring 35 that contacts the ceramic bottle 1.

[0063] like Figure 8 As shown, the dashed line represents the height of the glaze liquid, and the arrow indicates the direction of movement of the slide plate 33. When glazing, the center of the bottle bottom is located at the liquid surface, the inner wall of the bottle mouth is below the liquid surface, and the inner wall of the bottle neck is above the liquid surface. The ceramic bottle 1 rotates at this tilt angle, and the bottom of the bottle faces the direction of movement of the slide plate 33. This allows for glazing of the outer wall of the ceramic bottle 1 and the inner wall of the bottle mouth, while preventing the glaze liquid from entering the bottle body.

[0064] In actual use, the pneumatic inner support fixing mechanism 2 is initially in a vertical state and the inner sleeve 12 extends out of the outer sleeve 10. After the pressurizing component 6 slides with the slide plate 33 to the top of the ceramic bottle 1, the ceramic bottle 1 is pushed down by the extension of the telescopic push rod 32. The pressurizing component 6 will enter the interior of the ceramic bottle 1 until the rubber ring 35 abuts against the inner wall of the bottom of the bottle.

[0065] Subsequently, the telescopic push rod 32 continues to extend, and the inner sleeve 12 will retract into the outer sleeve 10. At this time, due to the presence of the one-way valve 17, the inside of the pressurizing component 6 is not connected to the outside, so the internal air pressure of the pressurizing component 6 will increase, and the air bag 11 will also inflate and expand, pressing against the inner wall of the ceramic bottle 1.

[0066] As the internal air pressure of the pressurizing component 6 increases, the pressure of the gas on the ratchet rack 23 can overcome the elastic force of the tension spring 25 and make the ratchet rack 23 tend to slide outward. In this state, the ratchet rack 23 can form a one-way sliding engagement with the ratchet ring 21, which allows the inner sleeve 12 to retract into the ceramic bottle 1 under the thrust of the telescopic push rod 32. However, when the telescopic push rod 32 removes the thrust, the inner sleeve 12 will not extend out of the outer sleeve 10.

[0067] Once the airbag 11 inflates and presses against the inner wall of the ceramic bottle 1 with a certain amount of pressure, the ceramic bottle 1 can be picked up.

[0068] Subsequently, the telescopic push rod 32 retracts, lifting the pneumatic internal support fixing mechanism 2, the automatic high-pressure holding mechanism 3, and the ceramic bottle 1 as a whole. Then, the swing motor 30 adjusts the ceramic bottle 1 from a vertical position to a horizontal position. Figure 8 The tilted state shown indicates that the device can be displaced as a whole by driving the slide plate 33 through an external mechanism.

[0069] When ceramic bottle 1 reaches the glazing station, motor 9 slowly rotates ceramic bottle 1; after ceramic bottle 1 reaches above the glaze, the extension of telescopic push rod 32 moves ceramic bottle 1 horizontally downwards. Figure 8 The height shown indicates that the bottom of the bottle faces the direction of movement of the slide plate 33, thus allowing glazing to be applied to both the outer wall of the ceramic bottle 1 and the inner wall of the bottle mouth, while preventing glaze from entering the interior of the bottle.

[0070] After rotating once in the glaze, the ceramic bottle 1 rises and is then adjusted to a vertical position. During the subsequent movement, the glaze layer is first dried before being placed in the kiln for firing.

[0071] When it is necessary to release ceramic bottle 1, first place ceramic bottle 1 on a flat surface by extending telescopic push rod 32. Then, temporarily open one-way valve 17 to release the gas inside the pressurizing component 6. As the internal gas pressure of pressurizing component 6 decreases, the gas thrust on ratchet 23 will gradually decrease. When it is less than the tension of tension spring 25, ratchet 23 will retract and leave ratchet ring 21. At this time, the one-way valve 17 can be stopped from opening.

[0072] Subsequently, the telescopic push rod 32 retracts, causing the pneumatic inner support fixing mechanism 2 to rise. Since the outer sleeve 10 and the inner sleeve 12 tend to move away from each other under the elastic force of the return spring 14, the inner sleeve 12 will first rise independently relative to the outer sleeve 10. At this time, the internal air pressure of the pressurization component 6 decreases, and the gas in the airbag 11 will be completely extracted first. Then, the external air will enter the interior of the pressurization component 6 through the one-way valve 17. Therefore, the internal air pressure of the pressurization component 6 is always slightly lower than the external atmospheric pressure.

[0073] Once the inner sleeve 12 extends to its limit, it will rise together with the outer sleeve 10, leaving the ceramic bottle 1 in place, thus completing the release of the ceramic bottle 1.

[0074] When the check valve 17 is not open, it functions as a normal check valve, allowing only external gas to enter the pressurization assembly 6, while preventing the gas inside the pressurization assembly 6 from being released. When the check valve 17 is opened, the gas can flow in both directions. The methods for opening the check valve 17 include, but are not limited to, the following:

[0075] Method 1: Manually control the opening of the one-way valve 17. This method is suitable for semi-automatic production lines, i.e., when workers are responsible for transferring the ceramic bottle 1 after it is released.

[0076] Method 2: A push pin can be set up. The sliding of the slide plate 33 will cause the one-way valve 17 to contact the push pin. After the push pin touches the valve core of the one-way valve 17, the one-way valve 17 can be opened, similar to the tire valve.

[0077] Method 3: The one-way valve 17 can be set as an electrically controlled valve. However, since the one-way valve 17 needs to rotate with the inner sleeve 12, the one-way valve 17 needs to be controlled by wireless signal and has an independent battery. This solution is relatively complicated.

[0078] To improve control precision, a pressure sensor can also be installed inside the outer sleeve 10 to limit the upper limit of the pressure inside the pressurization component 6, thus preventing the ceramic bottle 1 from being damaged when the pressure of the airbag 11 is too high.

[0079] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0080] The present invention and its embodiments have been described above.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
