Description

Technical Field

[0001] The invention relates to the technical field of ceramic kilns, and in particular to an active rod pressing device for a ceramic kiln. Background Art

[0002] The roller kiln is an advanced, energy-saving, fast-firing kiln with advantages such as a small temperature difference, a high degree of automation, and a high firing yield. It is an ideal kiln for the ceramic industry for firing products such as glazed tiles and wall and floor tiles. The kiln roller is a key component of the roller kiln and plays an important role in transmitting and supporting the products during the high-temperature firing process of ceramic products. In the existing technology, one end of the kiln roller is connected to the active drive shaft, and the other end is supported by a support plate or bearing. During the operation of the ceramic kiln, when the kiln roller rotates, it will produce a small jump due to load deformation and other problems. This jump is amplified at the end of the kiln roller away from the drive shaft, leaving a roller mark on the porcelain glazed tiles, affecting product quality. Summary of the Invention

[0003] The main purpose of the present invention is to provide an active rod pressing device for a ceramic kiln to solve the above problems.

[0004] To achieve the above-mentioned purpose, the present invention provides an active rod pressing device for a ceramic kiln, comprising a cylinder connecting plate, which is fixedly connected to the ceramic kiln body; a cylinder is arranged on the cylinder connecting plate; a pressure plate is fixedly connected to the end of the cylinder shaft of the cylinder; it also includes a rod pressing plate, and a plurality of bearings are evenly arranged on one side of the rod pressing plate; the bearings are used to abut against the driven end of the kiln roller away from the active transmission shaft; a plurality of pressure plate guide rods are arranged on the top of the pressure plate, and the pressure plate guide rods are slidably connected to the pressure plate; a floating spring is provided on the outside of the pressure plate guide rod; one end of the floating spring abuts against the top of the pressure plate, and the other end abuts against the bottom of the pressure plate.

[0005] Furthermore, the top end of the pressure plate guide rod passes through the pressure plate and is provided with a limiting portion, and the limiting portion is used to prevent the pressure plate guide rod from escaping from the pressure plate.

[0006] Furthermore, two shaft sleeves are symmetrically arranged on both sides of the cylinder on the cylinder connecting plate; two cylinder guide rods respectively adapted to the two shaft sleeves are arranged on the top of the pressure plate; the cylinder guide rod is slidably arranged in the shaft sleeve; a cylinder spring is arranged on the outer sleeve of the cylinder guide rod; the lower end of the cylinder spring abuts against the shaft sleeve, and the upper end is fixedly connected to the gasket on the top of the cylinder guide rod.

[0007] Furthermore, the bearing is connected to the rod pressing plate through an eccentric adjustment device.

[0008] Furthermore, the eccentric adjustment device includes an eccentric shaft connecting plate, a first rotating shaft is provided at one end of the eccentric shaft connecting plate, and a second rotating shaft is provided at the other end, and the first rotating shaft and the second rotating shaft are respectively provided on opposite sides of the eccentric shaft connecting plate; the first rotating shaft is fixedly connected to the inner ring of the bearing, and the second rotating shaft is rotatably connected to the pressure bar plate.

[0009] The present invention has the following beneficial effects:

[0010] This invention utilizes an air-suspended bar-holding plate mounted on a bearing to contact the kiln rollers, limiting their bounce. Downward pressure from the cylinder is transmitted through a floating spring to the bar-holding plate, ensuring that the plate and bar-holding plate can move up and down, ensuring that the downward pressure limiter does not damage the kiln rollers. The device utilizes an air-suspended bar-holding plate, a floating spring design, and thermal insulation to ensure that normal kiln operations, such as firing, fire monitoring, cotton plugging, oiling, maintenance, and bar replacement, are not affected.

DETAILED DESCRIPTION

[0014] In order to achieve the above-mentioned objectives and effects, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0015] like Figure 1-2As shown, the present invention provides an active rod pressing device for a ceramic kiln, comprising a cylinder connecting plate 5, which is fixedly connected to the ceramic kiln body; a cylinder 1 is provided on the cylinder connecting plate 5; the outer sleeve of the cylinder 1 is provided with a heat insulating sleeve; the end of the cylinder shaft 6 of the cylinder 1 is fixedly connected to a pressure plate 9; a rod pressing plate 11 is also provided, and a plurality of bearings 12 are evenly provided on one side of the rod pressing plate 11; the bearings 12 are used to abut the driven end of the kiln roller 13 away from the active transmission shaft; a plurality of plate guide rods 8 are provided on the top of the rod pressing plate 11, and the plate guide rods 8 are slidably connected to the plate 9; a floating spring 10 is provided on the outer sleeve of the plate guide rod 8; one end of the floating spring 10 abuts the top of the rod pressing plate 11, and the other end abuts the bottom of the plate 9. This solution uses the bearings 12 installed on the air-suspended rod pressing plate 11 to contact the kiln roller 13, limiting the bouncing amplitude of the kiln roller 13. The downward pressure of cylinder 1 is transmitted through floating spring 10 to bar press plate 11, ensuring that bar press plate 9 and bar press plate 11 can move up and down within a certain range, ensuring that the downward pressure limit does not damage the kiln rollers. The device uses a cylinder to move the bar press component up and down, a floating spring structure design, and thermal insulation protection, without affecting normal operations such as kiln firing, fire observation, cotton plugging, oiling and maintenance, and bar replacement.

[0016] In another embodiment, the top end of the pressure plate guide rod 8 passes through the pressure plate 9 and is provided with a limiting portion (not shown), which is used to prevent the pressure plate guide rod 8 from falling off the pressure plate 9.

[0017] In another embodiment, two bushings 4 are symmetrically mounted on the cylinder connecting plate 5, located on either side of the cylinder 1. Two cylinder guide rods 7, each corresponding to the two bushings 4, are mounted on the top of the pressure plate 9. The cylinder guide rods 7 slide within the bushings 4. A cylinder spring 3 is sheathed around the outer surface of the cylinder guide rods 7. The lower end of the cylinder spring 3 abuts the bushing 4, while the upper end is fixedly connected to the washer 2 on the top of the cylinder guide rod 7. The cylinder spring 3 balances the weight of the downward pressure component, keeping the cylinder shaft 6 suspended.

[0018] In another embodiment, the bearing 12 is connected to the bar press plate 11 via an eccentric adjustment device. The eccentric adjustment device includes an eccentric shaft connecting plate 14, with a first rotating shaft 15 disposed at one end and a second rotating shaft 16 disposed at the other end. The first rotating shaft 15 and the second rotating shaft 16 are disposed on opposite sides of the eccentric shaft connecting plate 14. The first rotating shaft 15 is fixedly connected to the inner ring of the bearing 12, and the second rotating shaft 16 is rotatably connected to the bar press plate 11. Eccentric adjustment allows the position of each kiln roller 13 to be determined, as well as the amplitude of its bounce to be limited.

[0019] The above descriptions are only preferred embodiments of the present invention, not all embodiments. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
