Description

Technical Field

[0001] The invention belongs to the technical field of glass production equipment and relates to a laminated glass production line. Background Art

[0002] Laminated glass is a composite glass made of two or more pieces of glass with one or more layers of organic polymer as an intermediate film in the middle, which is then treated with high temperature and high pressure to permanently bond the glass and the intermediate film together. During the production process, the laminated glass is first heated to soften the intermediate colloid, and a certain pressure is applied to squeeze out bubbles and enhance the bonding strength. The intermediate colloid is then solidified by cooling to produce the finished laminated glass.

[0003] Due to the pressure between the clips that need to be maintained, the stress caused by temperature changes, the deformation of defective glass due to heat, and other reasons, the glass cup may be crushed during the online cooling process after heating. In the existing method, manual online care is required. If the glass is broken, the machine needs to be stopped in time. On the one hand, the broken glass is cleaned up to prevent it from affecting the subsequent glass transportation. On the other hand, the heating of the glass needs to be controlled to avoid the glass in the heating zone being heated for too long during the shutdown process. However, the shutdown affects the processing continuity of the laminated glass and will also affect the quality of the batch of laminated glass. Summary of the invention

[0004] The purpose of the present invention is to provide a laminated glass production line in view of the above problems existing in the prior art. The technical problem to be solved by the present invention is how to keep the production line running continuously when glass breakage occurs.

[0005] The object of the present invention can be achieved through the following technical solutions: a laminated glass production line, characterized in that it includes a heating conveying zone and a cooling conveying zone connected to the end of the heating conveying zone, the cooling conveying zone includes a frame, an upper pressure roller and a plurality of lower pressure rollers, each upper pressure roller is rotatably connected to the frame, the two ends of the lower pressure roller are respectively connected to the frame through a first column, an induction slag removal roller is arranged between adjacent lower pressure rollers, the plane where each induction slag removal roller is located is lower than the plane where each lower pressure roller is located, the two ends of the induction slag removal roller are respectively connected to the frame through a second column, and a slag removal gap is provided between the lower pressure roller and the induction slag removal roller adjacent thereto;

[0006] The frame is rotatably connected to a driving shaft, the driving shaft is provided with a plurality of first pulleys corresponding to the lower pressure rollers one by one, the lower pressure roller is fixedly provided with a second pulley adapted to the first pulley, and a belt is connected between the first pulley and the second pulley;

[0007] The induction slag removal roller comprises a roller sleeve, a central shaft and two sensor components respectively arranged at both ends of the central shaft, the central shaft is provided with a plurality of mounting holes, each mounting hole is perpendicular to the axis of the central shaft, a positioning rod is inserted into the mounting hole, the outer end of the positioning rod is fixedly connected to the inner wall of the roller sleeve, the positioning rod is sleeved with a compression spring resting between the inner wall of the roller sleeve and the outer wall of the central shaft, each positioning rod is in the same plane, and the connection points between adjacent positioning rods and the roller sleeve have a phase angle of 180°;

[0008] The sensor assembly includes a mounting sleeve rotatably connected to the end of the central axis, the mounting sleeve is fixedly connected to the second column, two symmetrically distributed trigger rods are fixedly arranged on the central axis, the trigger rods are arc-shaped, and the inner wall of the mounting sleeve has a through ear for guiding the trigger rod. A reset spring is sleeved on the trigger rod, and the two ends of the reset spring are respectively fixedly connected to the through ear and the central axis. A pressure sensor is arranged on the mounting sleeve, and the pressure sensor can be triggered by the end of the trigger rod when the trigger rod rotates relative to the mounting sleeve.

[0009] Furthermore, a guide hole is provided on the mounting sleeve, a push rod is slidably connected in the guide hole, an adjusting bolt is threadedly connected in the guide hole, the pressure sensor is arranged on the adjusting bolt, an avoidance hole is provided in the push rod, a return spring is inserted in the avoidance hole, and two ends of the return spring respectively abut between the adjusting bolt and the top surface of the avoidance hole.

[0010] Furthermore, the heating and conveying area includes a sealed heating chamber, and a plurality of conveying rollers are arranged at the bottom of the heating chamber, and the conveying rollers are driven by a driving shaft.

[0011] Furthermore, the pressure sensor is connected to an alarm.

[0012] Furthermore, the first pulley is connected to the drive shaft via an overrunning clutch.

[0013] Furthermore, the circumferential surfaces of the lower pressure roller and the induction slag removal roller are provided with spiral convex ribs.

[0014] Furthermore, the lower pressure roller and the induction slag removal roller are provided with a plurality of avoidance areas.

[0015] The laminated glass after being combined is fed into the entrance of the heating conveying area. The laminated glass is heated in the feeding conveying area and transported to the cooling conveying area. Under the pressure of the upper and lower pressure rollers, the laminated glass is slowly cooled and continuously pressurized.

[0016] When the cooling and conveying area is damaged due to various reasons, since the laminated glass at this time is an unframed composite glass, the broken glass is in blocks, and some of it falls from the avoidance area to the bottom of the cooling and conveying area. The glass blocks that fail to pass through the avoidance area or are not in the avoidance area will continue to be squeezed by the upper and lower pressure rollers and quickly break into blocks or particles.

[0017] Complete laminated glass cannot come into contact with the induction slag removal roller, but when it is broken, it will come into contact with the induction slag removal roller. The squeezing force makes the induction slag removal roller "eccentric" and rotates at a certain angle, so that the glass fragments fall into the slag storage space below through the gap between the induction slag removal roller and the lower pressure roller.

[0018] The principle of "eccentricity" achieved by the induction slag removal roller under pressure: glass fragments squeeze the roller sleeve of the induction slag removal roller. During the rotation of the lower pressure roller, the glass fragments squeeze the compression spring, causing the roller sleeve to deviate from the center axis to achieve eccentricity.

[0019] The principle of the induction slag removal roller sending an alarm signal to the alarm when broken glass appears: although the roller sleeve is offset relative to the central axis when glass fragments squeeze the roller sleeve, the rotation of the roller sleeve and the central axis can be kept synchronous, so that the adjacent lower pressure roller squeezes the glass fragments during rotation, causing the roller body and the central axis of the induction slag removal roller to rotate accordingly, and the central axis rotates synchronously with the trigger rod, and the trigger rod rotates at a certain angle relative to the mounting sleeve. The trigger rod squeezes the push rod and makes the push rod rest on the pressure sensor, thereby triggering the pressure sensor. The pressure sensor transmits the signal to the alarm and performs an action corresponding to the "broken glass" signal, such as a sound prompt.

[0020] Each induction slag removal roller is numbered so that the corresponding data of the location where the glass breakage occurs can be obtained at the monitoring end.

[0021] This production line can not only realize the online cleaning of broken glass and make it fall into the corresponding position away from the cooling and conveying area without stopping the line, but also realize the prompt function. When there is no one online to supervise, after receiving the damage signal, staff will be arranged to take care of it in order to respond to emergencies or deal with other faults and adverse conditions that cannot be completed automatically.

[0022] The overrunning clutch arranged between the first pulley and the driving shaft can ensure that when the rotation of one or more lower pressing rollers is blocked, the normal operation of other lower pressing rollers will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The induction slag removal roller 3 includes a roller sleeve 31, a central shaft 32 and two sensor components respectively arranged at both ends of the central shaft 32. The central shaft 32 is provided with a plurality of mounting holes, each of which is perpendicular to the axis of the central shaft 32. A positioning rod 33 is inserted into the mounting hole. The outer end of the positioning rod 33 is fixedly connected to the inner wall of the roller sleeve 31. The positioning rod 33 is sleeved with a compression spring 34 that abuts between the inner wall of the roller sleeve 31 and the outer wall of the central shaft 32. Each positioning rod 33 is in the same plane, and the connection points between adjacent positioning rods 33 and the roller sleeve 31 have a phase angle of 180°.

[0033] The sensing assembly includes a mounting sleeve 35 rotatably connected to the end of the central shaft 32, the mounting sleeve 35 is fixedly connected to the second column 28, two symmetrically distributed trigger rods 36 are fixedly provided on the central shaft 32, the trigger rods 36 are arc-shaped, and an ear 37 for guiding the trigger rod 36 is provided on the inner wall of the mounting sleeve 35. A reset spring 38 is sleeved on the trigger rod 36, and the two ends of the reset spring 38 are respectively fixedly connected to the ear 37 and the central shaft 32, and a pressure sensor 39 is provided on the mounting sleeve 35. The pressure sensor 39 can be triggered by the end of the trigger rod 36 when the trigger rod 36 rotates relative to the mounting sleeve 35.

[0034] A guide hole is provided on the mounting sleeve 35, a push rod 41 is slidably connected in the guide hole, an adjusting bolt 42 is threadedly connected in the guide hole, the pressure sensor 39 is arranged on the adjusting bolt 42, an avoidance hole is provided in the push rod 41, a return spring 43 is inserted in the avoidance hole, and the two ends of the return spring 43 respectively abut between the adjusting bolt 42 and the top surface of the avoidance hole.

[0035] The heating and conveying area 1 includes a sealed heating chamber, and a plurality of conveying rollers 5 are arranged at the bottom of the heating chamber. The conveying rollers 5 are driven by a driving shaft 29 .

[0036] The pressure sensor 39 is connected to an alarm, and the first pulley 25 and the drive shaft 29 are connected via an overrunning clutch.

[0037] The lower pressure roller 23 and the induction slag removal roller 3 are provided with spiral convex ribs 44 on their circumferential surfaces, and the lower pressure roller 23 and the induction slag removal roller 3 are provided with a plurality of avoidance areas 45 .

[0038] The laminated glass after being combined is fed into the entrance of the heating conveying zone 1, where it is heated and transported to the cooling conveying zone 2. Under the pressure of the upper pressing roller 22 and the lower pressing roller 23, the laminated glass is slowly cooled and continuously pressed.

[0039] When the cooling conveying zone 2 is damaged due to various reasons, since the laminated glass at this time is an unframed composite glass, the broken glass is in blocks, and some of them fall from the avoidance zone 45 to the bottom of the cooling conveying zone 2. The glass blocks that fail to pass through the avoidance zone 45 or are not in the avoidance zone 45 will continue to be squeezed by the upper pressing roller 22 and the lower pressing roller 23 and quickly break into blocks or particles.

[0040] The intact laminated glass cannot contact the induction slag removal roller 3, but when it is broken, it will contact the induction slag removal roller 3. The squeezing force makes the induction slag removal roller 3 "eccentric" and rotates at a certain angle, so that the glass fragments fall into the slag storage space below through the gap between the induction slag removal roller 3 and the lower pressure roller 23.

[0041] The principle of "eccentricity" achieved by the induction slag removal roller 3 under pressure is as follows: glass fragments squeeze the roller sleeve 31 of the induction slag removal roller 3. During the rotation of the lower pressure roller 23, the glass fragments squeeze the compression spring 34, causing the roller sleeve 31 to deviate from the central axis 32 to achieve eccentricity.

[0042] The principle of the induction slag removal roller 3 sending an alarm signal to the alarm when broken glass appears is: although the roller sleeve 31 is offset relative to the central axis 32 when the glass fragments squeeze the roller sleeve 31, the rotation of the roller sleeve 31 and the central axis 32 can be kept synchronous, so that the adjacent lower pressure roller 23 squeezes the glass fragments during the rotation process, causing the roller body and the central axis 32 of the induction slag removal roller 3 to rotate accordingly, and the central axis 32 rotates synchronously with the trigger rod 36, and the trigger rod 36 rotates at a certain angle relative to the mounting sleeve 35, and the trigger rod 36 squeezes the push rod 41 so that the push rod 41 rests on the pressure sensor 39, thereby triggering the pressure sensor 39, and the pressure sensor 39 transmits the signal to the alarm, and performs an action corresponding to the "glass breakage" signal, such as a sound prompt.

[0043] Each induction slag removal roller 3 is numbered so that the corresponding data of the location where the glass breakage occurs can be obtained at the monitoring end.

[0044] This production line can not only realize the online cleaning of broken glass, causing it to fall into a corresponding position away from the cooling and conveying area 2 without stopping the line, but also realize the prompt function. When there is no one online to supervise, after receiving the damage signal, staff will be arranged to take care of it in order to respond to emergencies or deal with other faults and adverse conditions that cannot be completed automatically.

[0045] The overrunning clutch disposed between the first pulley 25 and the driving shaft 29 can ensure that when one or more lower pressing rollers 23 are blocked from rotating, the normal operation of other lower pressing rollers 23 will not be affected.

[0046] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
