Abstract

The invention relates to the field of ceramic roller production, in particular to a production system for ceramic rollers, a fixed dust collection device or a manual cleaning mode is mostly adopted for cleaning the end faces of the cut rollers, a fixed dust collection cover is adopted to face the end faces of the movable and inclined rollers, and due to the fact that a huge gap exists, the cleaning efficiency is greatly improved.

Description

Technical Field

[0001] This invention relates to the field of ceramic roller production, specifically to a production system for ceramic rollers. Background Technology

[0002] Ceramic rollers are essential components of modern high-temperature roller kilns of all types. They play a crucial role in bearing and transmitting loads during high-temperature manufacturing, withstand strong impacts and vibrations, and possess excellent corrosion resistance, making them resistant to chemical corrosion and extending the equipment's service life. Currently, the production process for ceramic rollers typically involves mixing ceramic raw materials, feeding them into an extruder for extrusion molding, cutting the extruded ceramic rollers, pre-drying them in a dryer, and finally firing them in a furnace to obtain the finished ceramic roller tube.

[0003] During the cutting process, dust, debris and other residues will inevitably be generated on the cut end face of the roller. If these residues are not effectively removed, they will solidify on the end face during the subsequent sintering process or peel off into the kiln. This will not only affect the flatness and sealing of the roller end face, but may also contaminate the products being transported, leading to product defects.

[0004] The following problems exist in the existing technology that have not been well resolved: the cleaning of the end face of the cut roller is mostly done by fixed dust collection devices or manual cleaning. The fixed dust collection hood is used to clean the moving and tilted end face of the roller. Due to the huge gap, most of the air drawn in comes from the air around the end face of the roller. The effective airflow that actually passes through the end face and carries the dust is very small, resulting in low suction efficiency and unsatisfactory cleaning effect. Summary of the Invention

[0005] The purpose of this invention is to provide a production system for ceramic rollers to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a production system for ceramic rollers, including an end-face cleaning assembly, suitable for removing residues generated on the cut end face after the roller has been cut. The end-face cleaning assembly includes a movable slide and a cleaning cover. The movable slide is slidably mounted on the outer wall of the roller conveyor via a guide rail mechanism and can reciprocate along the extension direction of the roller conveyor. The cleaning cover is fixedly connected to the bottom of the movable slide and extends into the roller conveyor, with its open end facing the path traversed by the cut end face of the roller.

[0006] An industrial dust collector is installed on the upper part of the movable slide. The industrial dust collector is connected to the inside of the cleaning housing through a suction pipe. An airflow channel assembly is provided inside the cleaning housing. During the cleaning process, the airflow channel assembly keeps in contact with the cutting end face of the roller to form a relatively closed cleaning area.

[0007] Preferably, the airflow channel assembly includes a support column fixedly installed on a movable slide. The support column is arranged along the axis of the cleaning cover. An insert shaft is fixedly connected to the support column perpendicular to its axis. A middle partition is connected to the insert shaft through a rotating joint. The middle partition is disposed in the internal space of the cleaning cover and a flexible sealing bladder is provided on the end face facing the inside of the cleaning cover. The flexible sealing bladder forms a deformable sealing connection with the inner wall of the cleaning cover.

[0008] Preferably, at least one air supply channel is provided on the side of the middle partition facing away from the opening end of the housing of the cleaning cover. The opening direction of the air supply channel is opposite to or lateral to the suction direction of the dust suction pipe, which ensures that the air entering from the air supply channel forms a main airflow that passes through the cutting end face of the roller under the action of negative pressure.

[0009] Preferably, a pair of limiting components are symmetrically arranged on the back end face of the partition away from the flexible sealing bladder. The two limiting components are arranged with the axis of the insertion shaft as the axis of symmetry. Each limiting component includes a limiting rod. One end of the limiting rod is connected to the outer wall of the partition through a ball joint to form a spherical pair. A fixed bracket is fixedly installed on the outer wall of the support column. A guide cavity is opened inside the fixed bracket. A conical guide block is fixedly connected in the guide cavity. The other end of the limiting rod extends into the guide cavity through a ball head and is provided with a connecting rod. The connecting rod is hinged to the ball head. A return spring is provided in the guide cavity. The return spring is connected to the connecting rod to apply a preload force to the limiting rod, so that the partition maintains a stable initial position relative to the insertion shaft. The inner cavity of the conical guide block has a conical flared structure. The ball head is accommodated in the conical guide block and can move freely along its inner wall.

[0010] Preferably, the inner wall of the cleaning cover is provided with a radial sealing part for sealing the outer circumferential surface of the roller bar. The radial sealing part includes an annular sealing bladder embedded in the inner wall of the cleaning cover, and a plurality of floats are evenly distributed on the shell wall of the cleaning cover along the circumference of the annular sealing bladder.

[0011] Preferably, the outer wall of the cleaning cover is fitted with an axially sliding adjusting ring, and a compression spring is provided between the adjusting ring and the cleaning cover. The inner wall of the adjusting ring is provided with a contour track, which is composed of a continuous transition between an inclined section and a flat section and maintains contact with the float. The support column is also provided with an adjustment part between the limiting component and the adjusting ring. The adjustment part is used to drive the adjusting ring to slide axially according to the deflection displacement of the middle partition, thereby driving the contour track to act on the float and achieve sealing of the outer peripheral surface of the roller.

[0012] Preferably, the adjusting part includes a rotating sleeve rotatably mounted on a support column. The outer wall of the rotating sleeve is provided with an arc-shaped guide groove. An adjusting guide rod is slidably mounted on the fixed bracket in a direction perpendicular to the axis of the rotating sleeve. One end of the adjusting guide rod is provided with a guide roller that rolls with the arc-shaped guide groove, and the other end is connected to the end of a connecting rod extending into the guide cavity. A protrusion is also fixedly provided on the outer periphery of the rotating sleeve, and a transmission roller that contacts and engages with the protrusion is provided at a corresponding position on the outer wall of the adjusting collar.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] In this invention, after the roller is cut by the cutting unit, it is conveyed forward along the roller conveyor. The moving slide moves the cleaning cover synchronously, so that the airflow channel assembly is attached to the cut end face of the roller. Under the action of the airflow channel assembly, a relatively closed cleaning area is formed inside the cleaning cover, which effectively restricts the mixing of external air and improves the suction effect of the suction pipe on the cut particles.

[0015] In this invention, under negative pressure, the airflow entering from the air supply channel is first guided to the back cavity formed by the flexible sealing bag and the partition plate, and then forced to pass through the dynamic sealing gap between the flexible sealing bag and the cutting end face of the roller, scouring the entire cutting end face, and finally being drawn away by the dust suction pipe carrying the detached particles.

[0016] In this invention, multiple circumferentially distributed floats transmit pressure, ensuring that the annular sealing bladder is subjected to consistent force at all points along the circumference, forming a complete and reliable annular seal, effectively preventing local leakage. At the same time, the annular sealing bladder can prevent scratches on the roller surface.

[0017] In this invention, when the industrial dust collector generates negative pressure through the suction pipe, it ensures that the suction force generated by the negative pressure is concentrated on the area of ​​the cutting end face, which improves the suction efficiency of the cutting residue, solves the problem of incomplete sealing caused by the tilt of the cutting end face, and avoids damage to the end face of the roller.

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1 to 11The present invention provides a technical solution: a production system for ceramic rollers, including an end face cleaning component 4, which is suitable for removing residues generated on the cut end face after the roller has been cut.

[0033] For example, the end face cleaning component 4 can be integrated into the roller blank cutting production line, specifically located in the roller table 3 area downstream of the cutting unit 2, and is used to simultaneously clean the end face during the roller conveying process. The production line includes an extrusion conveying unit 1, a cutting unit 2, and a roller table 3 in sequence. The extrusion conveying unit 1 is used to continuously extrude and form ceramic blanks and convey them to the roller table 3 in a predetermined direction. The cutting unit 2 is used to cut the extruded continuous roller into independent segments. The end face cleaning component 4 is arranged on the roller table 3 and is used to clean the cut end face of the roller when it is conveyed along the roller table 3 after cutting.

[0034] Specifically, the end face cleaning assembly 4 includes a movable slide 41 and a cleaning cover 42. The movable slide 41 is slidably mounted on the outer wall of the roller conveyor 3 via a guide rail mechanism and can reciprocate along the extension direction of the roller conveyor 3. The cleaning cover 42 is fixedly connected to the bottom of the movable slide 41 and extends into the roller conveyor 3, with its open end facing the path through which the roller bar cuts the end face.

[0035] An industrial dust collector 43 is provided on the upper part of the movable slide table 41. The industrial dust collector 43 is connected to the inside of the cleaning cover 42 through a dust suction pipe 44. An airflow channel assembly 5 is provided inside the cleaning cover 42. During the cleaning process, the airflow channel assembly 5 keeps in contact with the cutting end face of the roller to form a relatively closed cleaning area.

[0036] During operation, after the roller is cut by the cutting unit 2, it is conveyed forward along the roller conveyor 3. The moving slide 41 drives the cleaning cover 42 to move synchronously, so that the airflow channel assembly 5 is attached to the cutting end face of the roller. Under the action of the airflow channel assembly 5, a relatively closed cleaning area is formed inside the cleaning cover 42, which effectively restricts the mixing of external air and improves the suction effect of the dust suction pipe 44 on the cut particles.

[0037] In this embodiment, the airflow channel assembly 5 includes a support column 51 fixedly installed on the movable slide 41, and the support column 51 is arranged along the axis of the cleaning cover 42.

[0038] A shaft 52 is fixedly connected to the support column 51 perpendicular to its axis. A partition plate 53 is connected to the shaft 52 via a rotating joint. The partition plate 53 is disposed in the internal space of the cleaning cover 42, and a flexible sealing bladder 54 is disposed on the end face facing the inside of the cleaning cover 42. The flexible sealing bladder 54 forms a deformable sealing connection with the inner wall of the cleaning cover 42.

[0039] On the housing of the cleaning cover 42, at least one air supply channel 55 is provided on the side of the partition plate 53 facing away from the opening end. The opening direction of the air supply channel 55 is opposite to or lateral to the suction direction of the suction pipe 44, ensuring that the air entering from the air supply channel 55 forms a main airflow that directionally passes through the cutting end face of the roller under the action of negative pressure.

[0040] During operation, the cut roller moves along the conveying direction of the roller conveyor 3, and its cut end face gradually enters the interior of the cleaning cover 42. The roller is cut during the extrusion molding process. The cut end face of the roller usually has a certain tilt angle. When the tilted cut end face contacts the flexible sealing bladder 54 on the partition plate 53, the lateral force generated causes the partition plate 53 to deflect adaptively around the insertion shaft 52. The deflection movement of the partition plate 53 enables the flexible sealing bladder 54 to fit the cut end face with different tilt angles in real time, forming a dynamic seal. Under this sealing state, a cleaning chamber with controlled airflow path is formed inside the cleaning cover 42, reducing ineffective leakage gaps.

[0041] Under negative pressure, the airflow entering from the air supply channel 55 is first guided to the back cavity formed by the flexible sealing bag 54 and the partition plate 53, and then forced to pass through the dynamic sealing gap between the flexible sealing bag 54 and the cutting end face of the roller, scouring the entire cutting end face, and finally being drawn away by the dust suction pipe 44 carrying the detached particles.

[0042] In this embodiment, a pair of limiting components 6 are symmetrically arranged on the back end face of the partition plate 53 away from the flexible sealing bag 54, and the two limiting components 6 are arranged with the axis of the insertion shaft 52 as the axis of symmetry.

[0043] Each limiting component 6 includes a limiting rod 61. One end of the limiting rod 61 is connected to the outer wall of the middle partition 53 through a ball joint 62 to form a spherical pair. A fixed bracket 63 is fixedly installed on the outer wall of the support column 51. A guide cavity 64 is opened inside the fixed bracket 63. A conical guide block 65 is fixedly connected in the guide cavity 64. The other end of the limiting rod 61 extends into the guide cavity 64 through a ball head 68 and is provided with a connecting rod 66. The connecting rod 66 is hinged to the ball head 68. A return spring 67 is provided in the guide cavity 64. The return spring 67 is connected to the connecting rod 66 to apply a preload force to the limiting rod 61, so that the middle partition 53 maintains a stable initial position relative to the insertion shaft 52. The inner cavity of the conical guide block 65 has a conical flared structure. The ball head 68 is accommodated in the conical guide block 65 and can move freely along its inner wall.

[0044] During operation, when the inclined cutting end face of the roller pushes the partition plate 53 to deflect, the partition plate 53 drives the limiting rod 61 to move through the ball joint 62. The ball head 68 at the end of the limiting rod 61 slides in the conical cavity of the conical guide block 65. At the same time, the return spring 67 is compressed through the connecting rod 66, which can effectively avoid motion interference during the movement of the limiting rod 61. The preload provided by the return spring 67 ensures the stability of the partition plate 53 during normal operation, while allowing it to deflect adaptively when subjected to external force.

[0045] In this embodiment, the inner wall of the cleaning cover 42 is provided with a radial sealing part 7 for sealing the outer circumferential surface of the roller bar. The radial sealing part 7 includes an annular sealing bladder 71 embedded in the inner wall of the cleaning cover 42. A plurality of floats 72 are evenly distributed on the shell wall of the cleaning cover 42 along the circumference of the annular sealing bladder 71.

[0046] The outer wall of the cleaning cover 42 is fitted with an axially sliding adjusting ring 73, and a compression spring 74 is provided between the adjusting ring 73 and the cleaning cover 42. The inner wall of the adjusting ring 73 is provided with a contour track 75, which is composed of a continuous transition between an inclined section and a flat section and maintains contact with the float 72. The support column 51 is also provided with an adjusting part 8 between the limiting component 6 and the adjusting ring 73. The adjusting part 8 is used to drive the adjusting ring 73 to slide axially according to the deflection displacement of the middle partition 53, thereby driving the contour track 75 to act on the float 72 and achieve sealing of the outer circumference of the roller bar.

[0047] During operation, when the roller extends into the cleaning cover 42 and contacts the partition plate 53, the partition plate 53 deflects and shifts. The adjusting part 8 drives the adjusting collar 73 to slide axially, so that the tilting guide of the contour track 75 applies a radial force to the float 72, pushing the annular sealing bladder 71 to produce radial elastic deformation, thereby forming a circumferentially uniform and tight contact with the outer surface of the roller.

[0048] Pressure is transmitted by multiple circumferentially distributed floats 72, ensuring that the annular sealing bladder 71 is subjected to consistent force at all points along the circumference, forming a complete and reliable annular seal, effectively preventing local leakage, while the annular sealing bladder 71 can prevent scratches on the roller surface.

[0049] In this embodiment, the adjustment part 8 includes a rotating sleeve 81 rotatably mounted on the support column 51. The outer wall of the rotating sleeve 81 is provided with an arc-shaped guide groove 82. An adjustment guide rod 83 is slidably mounted on the fixed bracket 63 in a direction perpendicular to the axis of the rotating sleeve 81. One end of the adjustment guide rod 83 is provided with a guide roller 84 that rolls with the arc-shaped guide groove 82, and the other end is connected to the end of a connecting rod 66 extending into the guide cavity 64.

[0050] The outer periphery of the rotating sleeve 81 is also fixedly provided with a protrusion 85, and the outer wall of the adjusting collar 73 is provided with a transmission roller 86 that contacts and cooperates with the protrusion 85 at a corresponding position.

[0051] During operation, when the cutting end face of the roller contacts the partition plate 53 and applies a lateral force, the partition plate 53 deflects and is displaced through the two limit rods 61, causing the two adjusting guide rods 83 to drive the rotating sleeve 81 to rotate around its axis through the guide rollers 84. When the rotating sleeve 81 rotates, it pushes the transmission roller 86 through the protrusion 85 to drive the adjusting ring 73 to slide axially, applying radial pressure to the float 72, so that the annular sealing bladder 71 can effectively seal the outer circumference of the roller.

[0052] The flexible sealing bladder 54 forms a seal with the cut end face of the roller, and the annular sealing bladder 71 forms a circumferential seal with the outer circumferential surface of the roller. The two work together to restrict most of the airflow to the path from the air supply channel 55, through the cut end face of the roller, and finally being drawn away by the dust suction pipe 44. This effectively prevents airflow from entering from other gaps and ensures that the main airflow carrying debris has sufficient speed and directionality, thereby improving cleaning efficiency.

[0053] When the industrial dust collector 43 generates negative pressure through the suction pipe 44, it ensures that the suction force generated by the negative pressure is concentrated on the area of ​​the cutting end face, which improves the suction efficiency of cutting residue, solves the problem of incomplete sealing caused by the tilt of the cutting end face, and avoids damage to the end face of the roller.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
