Description

Technical Field

[0001] This utility model belongs to the field of material feeding and glazing technology, and specifically relates to a material feeding and glazing mechanism. Background Technology

[0002] The immersion glazing method, also known as the dipping glazing method, involves briefly immersing the ceramic body in a glaze slurry and then removing it. The glaze slurry adheres evenly to the surface of the body due to its absorbency, thus forming a glaze layer. The ceramic body has a certain degree of water absorption, while the glaze slurry contains moisture. When the body is immersed in the glaze slurry, the surface absorbs the glaze. Afterward, the body is removed from the glaze slurry, and excess glaze flows back into the glaze slurry under gravity, ultimately leaving a uniform glaze layer on the surface of the body.

[0003] While mechanically assisted dipping glazing can improve efficiency, reduce manual labor, and enhance consistency in porcelain glazing, the material handling mechanism used to fix the body still faces some challenges. First, the material handling mechanism must firmly grip the porcelain to prevent it from slipping during dipping or movement. Second, because the body strength is relatively low during glazing, excessive uneven pressure cannot be applied, otherwise it will cause deformation or breakage of the body. In addition, the clamping contact points need to be carefully designed to avoid leaving obvious clamping marks on the glazed surface or obstructing glaze coverage, thus reducing the difficulty of later processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a material picking and glazing mechanism, which addresses the problems of inconvenient clamping of material picking mechanisms and easy leaving of clamp marks at the fixed contact points in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A material-feeding and glazing mechanism includes a right-angle support arm, a guide rail, a slider, a first cylinder, and a second cylinder. A guide rail is horizontally fixed to the horizontal extension arm of the right-angle support arm. The slider slides along the guide rail. Limit blocks are provided at both ends of the guide rail, and a first cylinder is fixedly mounted on one of the limit blocks. The power output end of the movable rod of the first cylinder is fixedly connected to the slider. A second cylinder is fixedly connected to the slider. An inflation module is fixedly connected to the power output end of the movable rod of the second cylinder, and a support rod is fixedly connected below the inflation module. An airbag is fixedly wrapped around the outside of the support rod.

[0007] Furthermore, the inflation module includes a connecting block and an air chamber; the air chamber is a hollow structure inside the connecting block; the connecting block extends downward and is provided with a limiting and fixing ring; one end of the support rod is nested and fixedly installed inside the limiting and fixing ring; the bottom of the limiting and fixing ring has multiple air outlets communicating with the air chamber; the top of the air chamber extends upward and is provided with an air inlet; a solenoid valve is connected above the air inlet; and an air pump is connected to the solenoid valve via a pipe.

[0008] Preferably, a locking ring is fitted around the periphery of the limiting and fixing ring.

[0009] Preferably, the air bladder in the inflated state is in close contact with the inner wall of the blank to be glazed.

[0010] Furthermore, the upper part of the airbag is integrally provided with a limit stop ring.

[0011] Furthermore, a fixing groove is provided at one end of the support rod away from the inflation module, and an annular groove is provided in the fixing groove; the bottom of the airbag is locked into the fixing groove by a limiting bead, and a C-shaped elastic limiting ring is provided in the groove to prevent the limiting bead from moving downward.

[0012] Preferably, a pipe retainer is fixedly provided on the side of the second cylinder.

[0013] Preferably, the support rod is made of a flexible material.

[0014] Furthermore, an operating platform is provided at the bottom of the vertical extension arm of the right-angle support arm; the operating platform is rotatably connected to the bottom of the vertical extension arm; a stepper motor is provided under the operating platform; the power output end of the stepper motor passes through the operating platform and is connected to the bottom of the vertical extension arm for transmission.

[0015] Compared to existing technologies, this material handling and glazing mechanism firmly grips the porcelain body. The airbag's close contact with the inner wall of the body creates a flexible contact that prevents scratches or other damage. The applied pressure is uniform. Without interference from external clamping points, the applied glaze forms a smooth, continuous, and uniformly colored surface on the outside of the body, resulting in better gloss and visual appeal. It avoids glaze gaps or breaks caused by clamping. Especially for bodies with complex shapes, curved surfaces, or intricate patterns, traditional clamping methods easily lead to incomplete glaze coverage, affecting the finished product's appearance and artistic effect. This solution effectively avoids such problems, ensuring that every outer surface is uniformly and completely covered with glaze. Regardless of the body's shape, it achieves an ideal glazing effect, thereby improving the yield rate and market competitiveness of the porcelain. Attached Figure Description

Detailed Implementation

[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] Example 1, see Figure 1-5 ,

[0026] A material feeding and glazing mechanism includes a right-angle support arm 1, a guide rail 2, a slider 21, a first cylinder 3, and a second cylinder 31. The guide rail 2 is horizontally fixed on the horizontal extension arm 11 of the right-angle support arm 1. The slider 21 is slidably connected along the guide rail 2. Limiting blocks 22 are provided at both ends of the guide rail 2, and a first cylinder 3 is fixedly mounted on one of the limiting blocks 22. The power output end of the movable rod of the first cylinder 3 is fixedly connected to the slider 21. A second cylinder 31 is fixedly connected to the slider 21. An inflation module 4 is fixedly connected to the power output end of the movable rod of the second cylinder 31, and a support rod 5 is fixedly connected below the inflation module 4. An airbag 6 is fixedly wrapped around the outside of the support rod 5. A limiting stop ring 61 is integrally provided on the upper part of the airbag 6. This method utilizes the combination of the first cylinder 3, the second cylinder 31, the slider 21, and the guide rail 2 to achieve the effect of displacement movement. By taking advantage of the difference in volume between the inflated and deflated states of the airbag 6, it engages with the inner wall of the body to be glazed to achieve material removal. The setting of the limiting plug ring 61 enhances the stability of the airbag 6 in fixing the body, and also seals the opening of the body, preventing the glaze from accidentally flowing into the body during the external glazing process, thus affecting the production quality.

[0027] When inflated, the airbag 6 fits tightly against the inner wall of the body to be glazed. The airbag 6 is engaged with the opening of the body, providing a stable gripping force and ensuring that the body will not shake or shift during the glazing process. This method of using the inner lining of the airbag 6 to engage the material will not leave obvious clamp marks on the outer glazing surface, thus eliminating the problem of clamps blocking the glaze layer coverage.

[0028] Furthermore, the inflation module 4 includes a connecting block 41 and an air chamber 42; the air chamber 42 is a hollow structure inside the connecting block 41; the connecting block 41 extends downward and is provided with a limiting and fixing ring 43; one end of the support rod 5 is nested and fixedly disposed within the limiting and fixing ring 43; the bottom of the limiting and fixing ring 43 is provided with multiple air outlets 44 communicating with the air chamber 42; the multiple air outlets 44 are evenly distributed circumferentially to balance the impact when the airbag 6 is inflated; and to prevent a single air outlet 44 from being twisted and blocked by the part of the airbag 6 covered outside the support rod 5 when the airbag 6 is in the contracted state.

[0029] The air chamber 42 extends upward from the top and has an air inlet 45; an electromagnetic valve 46 is connected above the air inlet 45; an air pump 7 is connected to the electromagnetic valve 46 via a pipe; the air inlet of the airbag 6 is sleeved outside the limiting and fixing ring 43; a locking ring 47 that cooperates with the limiting and fixing ring 43 is sleeved and fixed on the outer side of the air inlet of the airbag 6; the locking ring 47 is used to achieve the sealing of the airbag 6.

[0030] Furthermore, a fixing groove 51 is provided at one end of the support rod 5 away from the inflation module 4, and an annular groove 52 is provided in the fixing groove 51; the bottom of the airbag 6 is engaged into the fixing groove 51 by a limiting bead 8, and a C-shaped elastic limiting ring 81 is provided in the groove 52 to prevent the limiting bead from moving downward. The relative fixed connection between the bottom of the airbag 6 and the support rod 5 is achieved by the cooperation of the limiting bead 8, the fixing groove 51, the groove 52 and the limiting ring 81.

[0031] Preferably, a pipe retainer 32 is fixedly provided on the side of the second cylinder 31. The pipe retainer 32 is used to regulate and arrange the pipe routing of components such as the air pump 7, so as to avoid the pipes being messy and affecting the operation of the mechanism. When the second cylinder 31 moves in extension and retraction, it guides and limits the moving pipes. The pipe part that moves up and down within the pipe retainer 32 is made of rigid material.

[0032] Preferably, the support rod 5 is made of a flexible material; such as a high-hardness TPU material or rubber material with a hardness of 90A-95A, which is close to the feel of hard plastic, but still maintains a certain degree of elasticity, so as to avoid accidental damage to the preform.

[0033] During the glazing process in porcelain production, firstly, the first cylinder 3 operates, driving the slider 21 to move along the guide rail 2, bringing the airbag 6 to the designated position, where the porcelain body to be glazed is placed directly below. The solenoid valve 46 opens, and the air pump 7 draws air into the air chamber 42 through the solenoid valve 46. Under atmospheric pressure, the airbag 6 tightly wraps around the outside of the support rod 5. Next, the second cylinder 31 starts, its movable rod pushing the inflation module 4 downwards, causing the support rod 5 to be inserted into the porcelain body along the opening of the body. At this time, the air pump 7 inflates the air chamber 42 through the solenoid valve 46. The gas enters the air chamber through the air inlet 45 and is then discharged through the air outlet 44 into the airbag 6. After inflation, the airbag 6 expands, tightly adhering to the inner wall of the porcelain body, achieving a stable gripping and securing of the body. The limiting sealing ring 61 is also inflated, sealing the opening of the porcelain body on the top outside of the opening.

[0034] Subsequently, the solenoid valve 46 closes, and with the movement of this mechanism, the blank is moved above the glaze pool. The moving rod of the second cylinder 31 moves downward, immersing the blank evenly in the glaze pool for a specified time. Then, the moving rod of the second cylinder 31 moves upward, pulling the blank out of the glaze pool and transferring it to the designated position before it falls. The solenoid valve 46 opens again, and the air pump 7 draws air to deflate the air bag 6. Under atmospheric pressure, the air bag 6 gradually wraps tightly around the outside of the support rod 5, thereby releasing the blank and completing the glazing operation for a single blank.

[0035] Compared with existing technologies, this material feeding and glazing mechanism firmly grips the porcelain body, and the airbag and the inner wall of the body form a flexible contact that will not cause scratches or other damage to the body, and the applied pressure is uniform; in addition, no clamping contact points are set on the outside of the body, so the glazing is uniform and the glaze surface is completely covered.

[0036] Example 2, see Figure 6 This embodiment is an improvement on embodiment 1.

[0037] Furthermore, an operating platform 13 is provided at the bottom of the vertical extension arm 12 of the right-angle support arm 1; the operating platform 13 is rotatably connected to the bottom of the vertical extension arm 12; a stepper motor 9 is provided below the operating platform 13; the power output end of the stepper motor 9 passes through the operating platform 13 and is connected to the bottom of the vertical extension arm 12 for transmission. The stepper motor 9 allows the vertical extension arm 12 to rotate around the Z-axis, thereby increasing the degree of freedom of movement of this material picking and glazing mechanism and adapting to more different application scenarios.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
