Technical Field

[0001] This utility model relates to the field of casting machine technology, and in particular to a casting machine preform roll clamping device. Background Technology

[0002] A casting machine is a specialized piece of equipment used to produce cast films. A high-precision electronic ceramic casting machine uses alumina as the main raw material for ceramic casting. First, the pulverized powder is mixed with binder, plasticizer, dispersant, and solvent to form a slurry with a certain viscosity. The slurry flows down from the hopper and is scraped and pressed onto a special green film by a doctor blade at a certain thickness. After drying and curing, it is peeled off to become a thin film of green film.

[0003] During operation, existing casting machines require timely replacement of the casting strip roll and clamping of the casting strip. However, existing clamping equipment cannot effectively clamp the casting strip roll, resulting in slow clamping speed and poor operational stability. Utility Model Content

[0004] In view of this, it is necessary to provide a strip roll clamping device for a casting machine to solve the problem of difficulty in clamping strip rolls in existing casting machine clamping equipment.

[0005] This utility model provides a strip roll clamping device for a casting machine, including: a casting machine body and a clamping assembly for clamping the strip roll. The clamping assembly includes a clamping cylinder, a pressing block, and an inflatable airbag. The clamping cylinder is inserted into the strip roll, and the clamping cylinder is provided with a groove adapted to the pressing block. The pressing block is slidably embedded in the groove. The airbag is installed in the clamping cylinder and can drive the pressing block to move radially along the clamping cylinder to press against the strip roll.

[0006] Furthermore, the pressing block is a wedge-shaped block, which is inclined along the axial direction of the clamping cylinder to form a wedge-shaped surface, and the wedge-shaped surface is positioned opposite the airbag.

[0007] Furthermore, the sharp end of the pressing block is hinged to the clamping cylinder, and the thick end of the pressing block is flexibly connected to the airbag.

[0008] Furthermore, the plurality of grooves are equidistantly arranged around the axis of the clamping cylinder, and each groove corresponds to one of the pressing blocks.

[0009] Furthermore, the clamping assembly also includes a mounting plate, the middle part of which is connected to the airbag, and the outer side of which is fixedly connected to the end of the clamping cylinder; the mounting plate is provided with an air nozzle connected to the airbag.

[0010] Furthermore, it also includes an inflation assembly, which includes an inflation head that can inflate the airbag through the air nozzle.

[0011] Furthermore, a turntable is provided at one end of the clamping cylinder that is relatively far from the mounting plate. One end of the turntable is fixedly connected to the end of the clamping cylinder, and the other end of the turntable is rotatably connected to the casting machine body.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] This embodiment describes a tape roll clamping device for a casting machine, which relates to the field of casting machine technology. By introducing an airbag 230 and an abutment block into the clamping assembly 200, the airbag 230 drives the abutment block to move relative to the inner wall of the tape roll 500, thereby achieving rapid clamping and stable connection of the tape roll 500.

[0030] Please see Figures 1 to 7 The present embodiment of a casting machine includes a casting machine body 100 and a clamping assembly 200. The casting machine can evenly and smoothly extend the clay onto the casting strip, and the clamping assembly 200 can quickly clamp the casting strip roll 500.

[0031] The clamping assembly 200 includes a clamping cylinder 210, a pressing block 220, and an inflatable airbag 230. The clamping cylinder 210 is inserted into the strip roll 500, and the strip roll 500 is entirely sleeved on the clamping cylinder 210, which can clamp the strip roll 500. The clamping cylinder 210 is provided with a groove 211 that matches the pressing block 220. The pressing block 220 is slidably embedded in the groove 211 and can move radially along the clamping cylinder 210. The airbag 230 is installed inside the clamping cylinder 210 and can drive the pressing block 220 to move radially along the clamping cylinder 210. The pressing block 220 moves relative to the inner wall of the clamping cylinder 210, pressing against the strip roll 500. The airbag 230 inflates much faster than traditional mechanical devices, quickly filling and providing clamping force, significantly improving clamping speed. The airbag 230 can provide appropriate clamping force as needed, avoiding the hassle of manual adjustment required by traditional clamping devices and simplifying operation. The airbag 230 indirectly acts on the strip roll 500 through the pressure block 220, preventing wear on the airbag 230 and extending its service life.

[0032] During use, the pressing blocks 220 have a retracted state and an ejected state relative to the clamping cylinder 210. In the retracted state, all the pressing blocks 220 are retracted into the clamping cylinder 210, which can prevent the pressing blocks 220 from obstructing the insertion of the strip roll 500. In the retracted state, the pressing blocks 220 eject radially along the clamping cylinder 210, completing the quick clamping and fixing of the strip roll 500.

[0033] In some embodiments, please refer to Figure 3 and Figure 5 The pressure block 220 is inclined along the axial direction of the clamping cylinder 210, forming a wedge-shaped surface. The wedge-shaped surface is positioned opposite the airbag 230, and the airbag 230 acts on the wedge-shaped surface. The gradually increasing clamping force of the wedge-shaped surface can evenly transmit the expansion force of the airbag 230 to the pressure block 220. As the airbag 230 expands, the wedge-shaped block moves along the axial direction, forming a gradually increasing clamping force to ensure that the strip roll 500 is stably clamped.

[0034] The inclined design of the wedge blocks ensures that the force applied to the strip roll 500 is not only vertical but also distributed at a certain angle. This prevents the clamping force from being too concentrated in one part, thus effectively avoiding problems such as uneven clamping, deformation or loosening of the strip roll 500.

[0035] In some embodiments, please refer to Figure 5The pointed end of the pressure block 220 is hinged to the clamping cylinder 210, and the larger end of the pressure block 220 is flexibly connected to the airbag 230. The hinged connection between the pointed end of the pressure block 220 and the clamping cylinder 210 allows the pressure block 220 to rotate or tilt within the clamping cylinder 210 around the hinge point. As the airbag 230 inflates, the pressure block 220 moves at a certain angle and direction, thereby dynamically adjusting the distribution of clamping force and providing more precise clamping action.

[0036] The thicker end of the pressure block 220 is flexibly connected to the airbag 230, allowing the expansion of the airbag 230 to directly act on the thicker end of the pressure block 220. Due to the flexible connection, the expansion of the airbag 230 can be transmitted to the pressure block 220 more smoothly and flexibly. The expansion force of the airbag 230 is no longer a direct linear clamping force, but rather provides a gradual force through the flexible connection, avoiding excessively abrupt or uneven clamping force on the preform roll 500, thereby improving the accuracy and adaptability of the clamping process. Simultaneously, when the airbag 230 relatively contracts, it can drive the pressure block 220 to converge through the flexible connection structure, preventing the thicker end of the pressure block 220 from obstructing the insertion of the preform roll 500.

[0037] In the specific implementation process, the flexible connection structure can be a rubber strip or a rubber block, with both ends of the rubber strip or rubber block connected to the surface of the airbag 230 and the wedge-shaped surface of the pressure block 220, respectively.

[0038] In some embodiments, a plurality of grooves 211 are equidistantly arranged around the axis of the clamping cylinder 210, and each groove 211 corresponds to a pressing block 220. By evenly distributing the plurality of grooves 211 around the clamping cylinder 210, it can be ensured that the pressing blocks 220 can uniformly apply clamping force to each part of the strip roll 500 during clamping. Each groove 211 corresponds to one pressing block 220, avoiding differences in clamping effect caused by uneven force, thereby improving the uniformity and stability of the clamping process.

[0039] When multiple grooves 211 are evenly distributed, each pressing block 220 on the clamping cylinder 210 can independently and evenly contact the strip roll 500 during the clamping process, which can avoid instability caused by excessive or insufficient force in one part. The movement of each pressing block 220 is subject to similar constraints, which prevents other parts from loosening or failing to be effectively clamped due to excessive clamping force in one area, further improving the stability of the clamping device during operation.

[0040] In some embodiments, please refer to Figure 2 and Figure 3The clamping assembly 200 also includes a mounting plate 240. The middle part of the mounting plate 240 is connected to the airbag 230, and the outer side of the mounting plate 240 is fixedly connected to the end of the clamping cylinder 210. The mounting plate 240 can provide a stable support structure for the airbag 230, enabling the airbag 230 to work more stably when inflated. The mounting plate 240 can fix the airbag 230 in a predetermined position, preventing the airbag 230 from shifting or deforming during operation, and ensuring that the force of the airbag 230 can be accurately transmitted to the pressure block 220 during clamping.

[0041] The air nozzle on the mounting plate 240 is connected to the airbag 230, allowing precise control of the inflation volume of the airbag 230, and thus precise adjustment of the degree of inflation of the airbag 230. This provides the clamping device with an adjustable airflow input system, which helps to adjust the inflation force of the airbag 230 according to actual needs, thereby precisely controlling the magnitude of the clamping force.

[0042] A casting machine's preform roll clamping device further includes an inflation assembly 300, which includes an inflation head 310 capable of inflating an air bag 230 via an air nozzle. The inflation head 310 acts as a control source for airflow, supplying gas to the air bag 230 through the air nozzle, thus precisely adjusting the inflation amount of the air bag 230. By controlling the airflow output of the inflation head 310, the degree of inflation of the air bag 230 can be precisely controlled, thereby precisely adjusting the clamping force of the clamping device.

[0043] The inflation head 310 can quickly inflate the airbag 230, making the clamping process faster. Compared with traditional mechanical clamping devices, the airbag 230 inflates faster, thus shortening the clamping time and improving overall production efficiency.

[0044] In some embodiments, please refer to Figure 2 A turntable 250 is provided at the end of the clamping cylinder 210 that is relatively far from the mounting plate 240. One end of the turntable 250 is fixedly connected to the end of the clamping cylinder 210, and the other end of the turntable 250 is rotatably connected to the casting machine body 100. The turntable 250 is connected to the far end of the clamping cylinder 210 and is rotatably connected to the casting machine body 100, allowing the clamping cylinder 210 to rotate around its axis. Through this rotational function, the clamping cylinder 210 can drive the strip roll 500 to rotate, cooperating with the casting machine to complete the feeding of the strip.

[0045] As a further embodiment, a strip roll clamping device for a casting machine further includes a drive assembly 400, which includes a servo motor 410. The servo motor 410 is rotatably connected to a turntable 250. The servo motor 410 can drive the strip roll 500 to slowly unwind, allowing the strip to gradually release material and complete the calendering process of the clay. The servo motor 410 has a high-precision speed regulation function, which can accurately control the unwinding speed of the strip roll 500. This means that the strip roll 500 can be unwound at a stable and controllable speed, effectively avoiding production problems caused by excessively fast or slow speeds during the unwinding process, such as unevenness or excessive stretching of the strip roll 500.

[0046] Workflow: First, the gas in the airbag 230 is released, causing the pressure block 220 to be in a retracted state. Then, the strip roll 500 is inserted into the clamping cylinder 210, allowing the strip roll 500 and the clamping cylinder 210 to engage. Next, air is inflated into the airbag 230 using the inflation head 310, causing the pressure block 220 to be in an extended state, thus securing the strip roll 500. The inflation action of the airbag 230 is faster than that of traditional mechanical devices, allowing it to quickly fill and provide clamping force, significantly improving clamping speed. The airbag 230 can provide appropriate clamping force as needed, avoiding the inconvenience of manually adjusting the clamping device required by traditional clamping devices, simplifying operation. The airbag 230 indirectly acts on the strip roll 500 through the pressure block 220, preventing wear on the airbag 230 and extending its service life.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
