Description

Technical Field

[0001] The invention relates to the technical field of a full-automatic optical glass hot-pressing roller forming machine, in particular to a full-automatic optical glass hot-pressing roller forming machine. Background Art

[0002] Optical glass is a special glass material with good optical properties. It plays a good role in medical, communication and other fields. In order to keep the glass surface smooth and avoid excessive burrs during production and processing, a special full-automatic optical glass hot pressing roller forming machine is used to produce optical glass blanks by high-temperature rollers and low-speed rolling.

[0003] When the common fully automatic optical glass hot pressing roller forming machine is used, the high temperature pre-treated glass blank is formed and rolled by continuous low-speed rolling with multiple groups of high-temperature rollers of different specifications. Since the glass has a good plastic effect at high temperature, it can be quickly formed under the high-temperature roller rolling. The common fully automatic optical glass hot pressing roller forming machine has a good plastic rolling effect when it is used, but there are still some problems:

[0004] 1. Since the specifications and spacing of the rods used in different stages of optical glass are different, and the rotation directions of adjacent rollers are opposite, the common CNC operation is more expensive and the operation is more complicated due to the large number of internal precision parts.

[0005] 2. Since the optical glass moves continuously at a low speed along the conveyor belt during the rolling process, if the tray shakes during this process, it is easy to cause wrinkles on the surface of the optical glass. Summary of the invention

[0006] The purpose of the present invention is to provide a fully automatic optical glass hot-pressing roller forming machine to solve the defects of the existing fully automatic optical glass hot-pressing roller forming machine, which has high use cost and complicated operation.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a fully automatic optical glass hot-pressing roller forming machine, comprising a base and a high-temperature resistant belt assembly, the top of the base is fixedly connected to a heat-insulating top frame, one end of the base is fixedly connected to a control panel, a feed port is provided on one side of the heat-insulating top frame, a dust-proof air curtain is installed above the feed port, a preheating bin is installed on one side of the bottom end of the heat-insulating top frame, electric heating walls are installed at both ends of the heat-insulating top frame, a transfer mechanism is provided on one side of the preheating bin, and the bottom end of the heat-insulating top frame is provided The other side of the high temperature resistant belt assembly is fixedly connected to a high temperature resistant belt assembly, one end of the high temperature resistant belt assembly is fixedly connected to a discharge plate, one side of the two ends of the high temperature resistant belt assembly is fixedly connected to an auxiliary adjustment structure, the auxiliary adjustment structure includes a first mounting frame, a support frame, a guide groove, a guide plate, a scissors frame, an internal threaded slider, a side frame, an adjustment groove, a mounting frame, a limiting protrusion, an anti-shake protrusion, an internal threaded groove, a mounting block and a pressure sensor, the first mounting frame is fixedly connected to one side of the two ends of the high temperature resistant belt assembly, and a limiting structure is arranged above the high temperature resistant belt assembly.

[0008] When in use, the whole machine is controlled by the control panel, and automatic door panels are installed at the positions of the feed port and the discharge plate. When the optical glass blank is being formed, the optical glass blank is placed on the top of the high temperature resistant tray and then pushed into the interior of the preheating bin for preheating treatment, so that the optical glass blank reaches the softening temperature, and then the high temperature resistant tray is driven by the side belt assembly to be transferred to the top of the high temperature resistant belt assembly, so that the high temperature resistant tray drives the softened optical glass blank to move continuously, and during the continuous movement, three groups of auxiliary adjustment structures continuously roll and shape the softened optical glass blank, and the three groups are divided into three stages, namely, the preforming stage: the roller group applies progressive pressure to initially roll it into an approximate shape, the precision pressing stage: refine the contour and control the thickness tolerance, and the shaping stage: eliminate residual stress and stabilize the size. After the blank is rolled and formed, the push rod pushes the high temperature resistant tray to drive the formed optical glass blank to be pushed outward along the discharge plate.

[0009] Preferably, the transfer mechanism includes a slide plate, a side frame, a side belt assembly, a limit block, a support plate and a drive assembly. The slide plate is slidably connected to the inside of the bottom end of the heat-insulating top frame, both ends of the top of the slide plate are fixedly connected to the side frames, the top of one end of the side frame is fixedly connected to the side belt assembly, the outer side wall of the side belt assembly is fixedly connected to the limit block, the bottom end of the side belt assembly is fixedly connected to the support plate, and a drive assembly is provided at the bottom of one end of the side frame. The limiting function of the limit block makes the transfer of the high-temperature resistant pallet smoother and more accurate.

[0010] Preferably, the limit blocks are distributed at equal intervals on the bottom of the outer belt of the side belt assembly, so that the side belt assembly can remain stable when clamping the high temperature resistant pallet.

[0011] Preferably, the driving assembly is a sliding rod that can be slidably connected to the support plate and a bidirectional threaded rod that can be threadedly connected to the two groups of support plates, so that the slide plate can be moved.

[0012] Preferably, a support frame is provided below the first mounting frame, and a guide groove is provided inside the support frame, and a guide plate is slidably connected to the top of the guide groove, and a scissors frame is hinged on the top of the guide plate, and an internally threaded slider is hinged on the top of the scissors frame, and a side frame is fixedly connected at both ends of the support frame, and an adjustment groove is provided at both ends of the side frame, and a mounting frame is slidably connected inside the side frame, and limiting protrusions are fixedly connected at both ends of the mounting frame, and anti-shake protrusions are fixedly connected at both ends of the mounting frame, and internally threaded grooves are provided inside at the middle positions of both ends of the mounting frame, and a mounting block is installed inside the mounting frame, and a pressure sensor is installed inside the top of the mounting block. Since the roller spacing can be adjusted through the adjustment groove, the spacing adjustment is more convenient.

[0013] Preferably, a sliding rod slidably connected to the internally threaded slider and a bidirectional threaded rod threadedly connected are provided at the bottom of the first mounting frame, so that the support frame can be moved up and down according to demand.

[0014] Preferably, the limiting protrusion and the mounting block are in an inlaid structure, so that the mounting block can remain stable.

[0015] Preferably, the limiting structure includes a second mounting frame, a limiting frame, a limiting groove, a slide seat, a one-way bearing, a spring, a limiting roller, a high temperature resistant tray and an auxiliary groove. The second mounting frame is fixedly connected to the two ends of the heat-insulating top frame through a bracket, the second mounting frame is suspended above the high temperature resistant belt assembly, the bottom end of the second mounting frame is fixedly connected to the limiting frame, a limiting groove is provided inside the limiting frame, a slide seat is slidably connected inside the limiting groove, a one-way bearing is installed inside the slide seat, a spring is installed on the top of the slide seat, one end of the one-way bearing is rotatably connected to the limiting roller, a high temperature resistant tray is provided on the top of the high temperature resistant belt assembly, and auxiliary grooves are provided at both ends of the high temperature resistant tray to make the movement of the high temperature resistant tray smoother.

[0016] Preferably, a plurality of the limiting grooves are provided inside the limiting frame, and the plurality of limiting grooves are distributed at equal intervals inside the limiting frame, so that the high temperature resistant pallet is always limited during the entire moving process.

[0017] Preferably, the inner side spacing between the two groups of limiting frames is the same as the width of the high temperature resistant tray, so that the high temperature resistant tray can move smoothly.

[0018] Compared with the prior art, the present invention has the following beneficial effects: by installing a plurality of installation frames at equal intervals in the side frame, each group of hot rollers is controlled by a single motor, and the spacing between the rollers can be adjusted by sliding on the inner side of the side frame. Since a plurality of limit blocks are fixed at equal intervals at the bottom end of the outer side of the belt of the side belt assembly, they can be inserted into the auxiliary groove, so that the transportation of the high-temperature resistant pallet is more stable, and the limit rollers arranged at equal intervals can be inserted into the inner side of the auxiliary groove, so that the high-temperature resistant pallet always moves horizontally, and the special mechanical structure of the one-way bearing allows the high-temperature resistant pallet to only move forward, thereby avoiding horizontal shaking of the high-temperature resistant pallet.

[0019] 1. The motor drives the two sets of internal thread sliders to move in opposite directions, so that the scissor frame gradually closes and pushes the support frame downward. As the bottom of the roller touches the glass blank, the pressure sensor gradually senses its pressure. When the pressure reaches a certain value, the control panel controls the motor to stop the support frame from pressing down, so that a certain pressure is always maintained between the roller and the glass blank for rolling;

[0020] Furthermore, the installation frame is slidably mounted by the anti-shake protrusion to adjust the spacing between the rollers, and the positioning of the installation frame is reinforced by a bolt penetrating the adjustment groove and threadedly connected to the internal thread groove, so that the adjustment of the spacing between the rollers is more convenient;

[0021] 2. When the optical glass blank is preheated to a certain degree, the automatic door on one side opens and the side belt assembly is inserted into the preheating chamber, and the driving assembly drives the side belt assembly to clamp the two ends of the high-temperature resistant tray, and the limit card block is inserted into the auxiliary groove, so that the high-temperature resistant tray can be stably transported to the top of the high-temperature resistant belt assembly;

[0022] 3. Since the two sides of the auxiliary groove are in the shape of trumpets, the limiting rollers will be inserted into the auxiliary grooves, and the one-way bearings connected to the limiting rollers can only move forward, so that the high temperature resistant pallet can move along the high temperature resistant belt assembly, and under the pressure of the elastic force of the spring, the movement of the high temperature resistant pallet is smoother.

[0035] See attached Figure 2 and Figure 3 By opening a groove on one side of the high temperature resistant belt assembly 8, and arranging a screw driven by a motor in the groove so that the slide plate 701 can move horizontally left and right along the groove, the control panel 10 controls the slide plate 701 to drive the side belt assembly 703 to insert into the preheating chamber 5. When the optical glass blank is preheated to a certain degree, the automatic door on one side opens and the side belt assembly 703 is inserted into the preheating chamber 5. The driving assembly 706 drives the side belt assembly 703 to clamp the two ends of the high temperature resistant tray 1208, and the limiting block 704 is inserted into the auxiliary groove 1209. When the side belt assembly 703 is driven, the high temperature resistant tray 1208 can be moved and pulled out, and the slide plate 701 drives the high temperature resistant tray 1208 to move in the direction of the high temperature resistant belt assembly 8, so that the high temperature resistant tray 1208 can be stably transported to the top of the high temperature resistant belt assembly 8.

[0036] An auxiliary adjustment structure 11 is fixedly connected to one side of both ends of the high temperature resistant belt assembly 8, and the auxiliary adjustment structure 11 includes a first mounting frame 1101, a support frame 1102, a guide groove 1103, a guide plate 1104, a scissors frame 1105, an internal thread slider 1106, a side frame 1107, an adjustment groove 1108, a mounting frame 1109, a limiting protrusion 1110, an anti-shake protrusion 1111, an internal thread groove 1112, a mounting block 1113 and a pressure sensor 1114. The first mounting frame 1101 is fixedly connected to one side of both ends of the high temperature resistant belt assembly 8, and a support frame 1102 is arranged below the first mounting frame 1101, and a guide groove 1103 is opened inside the support frame 1102. The top of the guide groove 1103 is slidably connected to the guide plate 1104, and the top of the guide plate 1104 is hinged with the scissors frame 1105. 05 is hinged with an internal thread slider 1106 at the top, and side frames 1107 are fixedly connected at both ends of the support frame 1102. Adjustment grooves 1108 are provided at both ends of the side frame 1107. The inside of the side frame 1107 is slidably connected with a mounting frame 1109. Limiting protrusions 1110 are fixedly connected at both ends of the inside of the mounting frame 1109. Anti-shake protrusions 1111 are fixedly connected at both ends of the mounting frame 1109. Internal thread grooves 1112 are provided at the middle positions of both ends of the mounting frame 1109. A mounting block 1113 is installed in the mounting frame 1109. A pressure sensor 1114 is installed in the top of the mounting block 1113. A sliding rod for which the internal thread slider 1106 can be slidably connected and a bidirectional threaded rod for threaded connection are provided at the bottom of the first mounting frame 1101. The limiting protrusion 1110 and the mounting block 1113 are inlaid structures.

[0037] See attached Figure 4 , Figure 5 , Figure 6 and Figure 7When the fully automatic optical glass hot-pressing roller forming machine is in use, the two-way threaded rod threadedly connected to the internal thread slider 1106 at the bottom of the first mounting frame 1101 is driven by a motor to make the two groups of internal thread sliders 1106 move in opposite directions, so that the scissor frame 1105 gradually closes together, and thereby pulls the guide plate 1104 to slide along the guide groove 1103, so that the support frame 1102 is pressed down. Since the roller is installed on the inner side of the side frame 1107, as the bottom of the roller touches the glass blank, the pressure sensor 1114 gradually senses its pressure. When the pressure reaches a certain value, the control panel 10 controls the motor to stop driving the movement of the internal thread slider 1106, so that a certain pressure is always maintained between the roller and the glass blank. Rolling is carried out, and each group of hot rollers is driven by a single motor, and the adjacent rollers rotate in opposite directions. Since the roller spacing directly affects the pressure range of the glass blank, in order to enable the glass blank to obtain the most suitable pressure gradient, the roller spacing needs to be adjusted according to the specifications of the glass blank. The common CNC operation is relatively cumbersome and has many parts and a high cost. For this reason, adjustment grooves 1108 are opened inside both ends of the side frame 1107, and the installation frame 1109 is slid by the anti-shake protrusion 1111 to adjust the spacing between each roller, and the positioning of the installation frame 1109 is reinforced by means of bolts passing through the adjustment groove 1108 and threaded connection with the internal thread groove 1112, so that the adjustment of the roller spacing is more convenient.

[0038] A limiting structure 12 is arranged above the high temperature resistant belt assembly 8, and the limiting structure 12 includes a second mounting frame 1201, a limiting frame 1202, a limiting groove 1203, a slide seat 1204, a one-way bearing 1205, a spring 1206, a limiting roller 1207, a high temperature resistant tray 1208 and an auxiliary groove 1209. The second mounting frame 1201 is fixedly connected to both ends of the heat-insulating top frame 2 through a bracket, and the second mounting frame 1201 is suspended above the high temperature resistant belt assembly 8. The bottom end of the second mounting frame 1201 is fixedly connected to the limiting frame 1202, and a limiting groove 1203 is arranged inside the limiting frame 1202. A slide seat 1204 is slidably connected inside, a one-way bearing 1205 is installed inside the slide seat 1204, a spring 1206 is installed on the top of the slide seat 1204, one end of the one-way bearing 1205 is rotatably connected to a limiting roller 1207, a high temperature resistant tray 1208 is arranged on the top of the high temperature resistant belt assembly 8, auxiliary grooves 1209 are provided at both ends of the high temperature resistant tray 1208, a number of limiting grooves 1203 are provided inside the limiting frame 1202, and the limiting grooves 1203 are evenly spaced inside the limiting frame 1202, and the inner spacing of the two groups of limiting frames 1202 is the same as the width of the high temperature resistant tray 1208.

[0039] See attached Figure 4 , Figure 8 and Fig. 9Since the high temperature resistant tray 1208 carries the optical glass blank and moves continuously at a low speed along the high temperature resistant belt assembly 8, and is rolled and formed by rollers at different stages during the movement, in order to avoid shaking during the rolling of the blank, a limit frame 1202 is suspended and installed above the high temperature resistant belt assembly 8. When the high temperature resistant tray 1208 is transferred to the top of the high temperature resistant belt assembly 8 by the transfer mechanism 7, the limiting roller 1207 on both sides of the auxiliary groove 1209 will be inserted into the auxiliary groove 1209, and the one-way bearing 1205 connected to the limiting roller 1207 can only be forward-transmitted, so that the high temperature resistant tray 1208 can move along the high temperature resistant belt assembly 8, and under the elastic force of the spring 1206, the movement of the high temperature resistant tray 1208 is more stable, avoiding excessive shaking during the rolling and forming process.
