Description

Technical Field

[0001] This utility model relates to the field of ceramic processing technology, and in particular to a ceramic blank rolling forming device. Background Technology

[0002] Ceramics is a general term for pottery and porcelain. It refers to silicate products made from inorganic non-metallic minerals such as clay, which are formed, dried, and fired. Ceramics are characterized by high hardness and corrosion resistance, and are widely used in daily life and industry. The processing of ceramics requires the rolling and shaping of clay blanks, thus necessitating the use of specialized rolling and shaping equipment.

[0003] Existing ceramic rolling forming devices generally place the blank in a mold and then roll it using a rolling assembly to achieve the forming purpose. For example, there is an automatic rolling forming device for daily-use ceramic blanks with existing patent publication number CN222511901U. Because clay blanks have high viscosity and plasticity, they are prone to plastic deformation during rolling, leading to adhesion between the blank and the rolling head surface. Furthermore, existing devices lack an integrated structure for removing the adhered blank, which affects the rolling forming effect. Therefore, we provide a ceramic blank rolling forming device. Utility Model Content

[0004] To address the problem in the background art that the blank easily sticks to the surface of the rolling head during the rolling process, this utility model provides a ceramic blank rolling device.

[0005] This utility model is achieved by the following technical solution: a ceramic blank rolling forming device, including a base and a blank removal assembly, a bracket is fixedly connected to the base, an electric push rod is fixedly connected to the bracket, a frame is fixedly connected to the telescopic end of the electric push rod, a motor is fixedly connected to the inner side of the frame, a rolling head is fixedly connected to the rotor end of the motor through a connecting shaft, and a mold is fixedly connected to the top of the base.

[0006] The blank removal assembly includes a connecting frame fixedly connected to a frame. The end of the connecting frame is hinged to a movable rod via a hinge. The end of the movable rod is provided with a scraper. The bottom of the frame and the connecting frame are fixedly connected to the same slide rod via a connecting seat. A slider is slidably connected to the outside of the slide rod. A connecting rod is hinged between the slider and the movable rod via a hinge. A spring is also sleeved on the outside of the slide rod. Two sets of fixed frames are symmetrically fixedly connected to the slider. Rollers are rotatably connected between the two sets of fixed frames. A guide rail is fixedly connected to the bracket, and the surface of the guide rail is in contact with the rollers.

[0007] As a further improvement to the above solution, the end of the movable rod is fixedly connected to a mounting bracket, and two sets of screw holes are symmetrically opened on the mounting bracket. Two sets of screw holes are symmetrically opened on the scraper. The same screw rod is inserted into the screw holes on the same side and the screw holes are symmetrically opened on the outside. Nuts are threaded to both sides of the screw rod.

[0008] As a further improvement to the above solution, the mold is located directly below the rolling head.

[0009] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the connecting seat and the slider, respectively.

[0010] As a further improvement to the above solution, the shape and size of the scraper are matched with the external size of the rolling head.

[0011] As a further improvement to the above solution, the guide rail is composed of a vertical section and an inclined section fixedly connected to the top of the vertical section.

[0012] As a further improvement to the above solution, the maximum included angle between the movable rod and the connecting frame is 90°.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses an electric push rod to drive the rolling head to rise vertically, enabling the rollers to roll vertically upwards on the guide rail. When the rollers roll to the surface of the inclined section, as the rolling head continues to rise, the rollers continue to roll along the inclined surface of the section. At this time, the rollers push the slider to slide towards one end of the sliding rod. Utilizing the hinged action between the slider, the movable rod, and the connecting rod, as well as the hinged action between the movable rod and the connecting frame, the movable rod deflects. The deflection of the movable rod then drives the scraper to deflect as well, allowing the scraper to contact the surface of the rolling head. The motor drives the rolling head to rotate, enabling the scraper to scrape off the blank material adhering to the surface of the rolling head, thus ensuring the rolling forming effect of the blank and making it highly practical.

[0015] 2. This utility model separates the scraper from the screw by rotating the nut, and then pulls out the screw, which makes it easy to quickly disassemble the worn scraper and, conversely, to quickly install a new scraper, thereby ensuring the thorough removal of the blank material and further improving the practicality of the device.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1:

[0023] Please combine Figure 1-3 A ceramic blank rolling forming device according to this embodiment includes a base 1, a bracket fixedly connected to the base 1, an electric push rod 2 fixedly connected to the bracket, a frame 3 fixedly connected to the telescopic end of the electric push rod 2, a motor fixedly connected to the inner side of the frame 3, a rolling head 4 fixedly connected to the rotor end of the motor through a connecting shaft, and a mold 5 fixedly connected to the top of the base 1, the mold 5 being directly below the rolling head 4.

[0024] A blank removal assembly for removing adhered blanks includes a connecting frame 101 fixedly connected to a frame 3. A movable rod 102 is hinged to the end of the connecting frame 101 via a hinge. A scraper 103 is provided at the end of the movable rod 102. The frame 3 and the bottom of the connecting frame 101 are fixedly connected to the same slide rod 104 via a connecting seat. A slider 105 is slidably connected to the outside of the slide rod 104. A connecting rod 106 is hinged between the slider 105 and the movable rod 102 via a hinge. An external spring 107 is also fitted, with its two ends fixedly connected to the connecting seat and the slider 105 respectively. Two sets of fixing brackets 108 are symmetrically fixedly connected to the slider 105, and rollers 109 are rotatably connected between the two sets of fixing brackets 108. A guide rail 110 is fixedly connected to the bracket, and the surface of the guide rail 110 is in contact with the rollers 109. The guide rail 110 is composed of a vertical section and an inclined section fixedly connected to the top of the vertical section. The maximum included angle between the movable rod 102 and the connecting bracket 101 is 90°.

[0025] The end of the movable rod 102 is fixedly connected to a mounting bracket 201. Two sets of screw holes 1 202 are symmetrically opened on the mounting bracket 201, and two sets of screw holes 203 are symmetrically opened on the scraper 103. The same screw 204 is inserted into the screw holes 1 202 and screw holes 203 on the same side. Nuts 205 are threaded on both sides of the screw 204 to facilitate quick assembly and disassembly of the scraper 103.

[0026] The implementation principle of the ceramic blank rolling forming device in this embodiment is as follows: First, the blank is placed in the mold 5. Then, the electric push rod 2 and the motor are started. The motor can drive the rolling head 4 to rotate. The electric push rod 2 can push the rotating rolling head 4 down to roll the blank in the mold 5. At the same time, the rolling head 4 can also drive the roller 109 to roll the lower part of the guide rail 110. Under the rebound action of the spring 107 and the sliding connection between the slider 105 and the slide rod 104, the slider 105 will slide towards one end of the slide rod 104. 5. The hinged connection between the movable rod 102 and the connecting rod 106, and the hinged connection between the movable rod 102 and the connecting frame 101, causes the movable rod 102 to deflect. When the roller 109 rolls to the vertical section, the movable rod 102 is perpendicular to the connecting frame 101. When the rolling head 4 descends to the lowest point, the scraper 103 will not contact the base 1. After the rolling forming is completed, the electric push rod 2 is controlled to drive the rolling head 4 to rise and reset. The electric push rod 2 drives the rolling head 4 to rise vertically, so that the roller 109 can move vertically upward on the guide rail 110. As the roller 109 rolls to the surface of the inclined section, and the rolling head 4 continues to rise, the roller 109 continues to roll along the inclined surface of the section. At this time, the roller 109 pushes the slider 105 to slide towards the other end of the slide rod 104. Utilizing the hinged connection between the slider 105, the movable rod 102, and the connecting rod 106, and the hinged connection between the movable rod 102 and the connecting frame 101, the movable rod 102 will reset. The reset of the movable rod 102 will then drive the scraper 103 to reset as well, thereby allowing the scraper 103 to move closer to the surface of the rolling head 4. When the rolling head... When the roller reaches its highest point, the scraper 103 is in contact with the surface of the roller head 4, and the roller 109 is also rolling to the highest point of the inclined section. The motor drives the roller head 4 to rotate, so that the scraper 103 can scrape off the blank material adhering to the surface of the roller head 4, thereby ensuring the rolling forming effect of the blank material. Finally, the nut 205 is rotated to separate it from the screw 204, and the screw 204 is pulled out, which makes it easy to quickly disassemble the worn scraper 103. Conversely, it can quickly install a new scraper 103, thereby ensuring the thorough removal of the blank material.

[0027] Example 2:

[0028] Based on Embodiment 1, the further improvement of this embodiment is that the shape and size of the scraper 103 are matched with the outer size of the roller head 4, so that the scraper 103 can fit into the surface of the roller head 4.
