Technical Field

[0001] The invention relates to the technical field of molding equipment, in particular to a non-cutting extrusion molding equipment for a hollow frame of a display. Background Art

[0002] In the production process of LCD TVs, the thin LCD screen is covered by a metal frame to ensure the anti-bending and stability of the LCD screen. At present, the metal frame is made by stamping. Since the metal frame is made of metal sheet material, a large piece of material in the middle of the metal frame is produced as waste during the production process, which greatly increases the production cost, thereby increasing the purchase expenditure of consumers and causing a great waste of resources.

[0003] In the prior art, the patent document with publication number CN104139128A discloses a method for forming an outer frame of a liquid crystal display screen, and the steps are as follows:

[0004] 1: Rolling forming: a roll of metal steel strip is placed in a special rolling forming machine. After repeated rolling of the mold at the same position, the steel strip is finally rolled into a steel strip profile B with a certain shape;

[0005] 2: Cut a "V" shape on the long metal profile B according to the set size;

[0006] 3: Bend four "V"-shaped openings to form an outer frame;

[0007] 4: Weld four "V"-shaped notches and connection points;

[0008] 5: Surface treatment.

[0009] The above method uses a long strip of metal strip to form the outer frame of the liquid crystal display screen, which will not cause any waste of material, and since each processing process will not produce waste, the production cost is greatly reduced. However, the prior art lacks a non-cutting extrusion molding equipment suitable for the production of hollow frames of displays, and the existing molding equipment is not convenient for improving the yield of the hollow frame of the display during extrusion molding through pre-rust removal, pre-cleaning, pre-tensioning and vibration extrusion. Based on this, the present invention provides a non-cutting extrusion molding equipment for the hollow frame of the display to solve the problems raised in the above background technology. Summary of the invention

[0010] The present invention aims at the technical problems existing in the prior art and provides a non-cutting extrusion molding device for a hollow frame of a display to solve the problem that the existing molding equipment is not convenient for improving the yield of the hollow frame of the display during extrusion molding by pre-rust removal, pre-cleaning, pre-tensioning and vibration extrusion.

[0011] The technical solution of the present invention to solve the above technical problems is as follows: a display hollow frame non-cutting extrusion molding device, including a frame, and also includes:

[0012] Unwinding component, used for continuous unwinding of strip;

[0015] Reciprocating ballast and forming mechanism, used for extrusion forming of released strip;

[0016] The shaping mechanism is used for shaping the extruded strip.

[0017] Based on the above technical solution, the present invention can also be improved as follows.

[0018] Furthermore, the unwinding component includes a winding roller rotatably connected to a frame, a winding motor is installed on the surface of the frame, the winding roller is driven by the unwinding motor, a rolled strip is wound on the winding roller, a cavity is opened inside the winding roller, a group of inner support bags distributed in a circular array and cooperating with the rolled strip are installed on the winding roller, the inner cavity of each of the inner support bags is connected to the cavity, a pressure control pump is installed on the frame, the port of the pressure control pump is connected to the cavity through a pipeline, an air pressure probe is fixedly provided at the connection point between the pressure control pump and the cavity, a plurality of belt material wheels are rotatably connected between the inner surface of the frame, each of the belt material wheels is in contact with the strip, a transmission motor is installed on the side of the frame, and the output shaft end of the transmission motor is fixedly connected to one of the belt material wheels.

When the rolled strip is mounted on the roller, the inner support bag is sufficiently pressurized, and after the inner support bag is sufficiently pressurized, the rolled strip is effectively fixed on the roller.

[0020] When the belt wheel rotates, the rotation speed of the belt wheel is the same as the rotation speed of the winding roller;

[0021] When it is necessary to remove the unused coiled strip from the roller, the gas inside the inner support bag is fully emptied. After the gas inside the inner support bag is fully emptied, the unused coiled strip can be quickly removed from the roller.

[0022] Furthermore, the rust removal and pre-cleaning components include two brush shafts rotatably connected to the inner wall of the frame, the two brush shafts are driven by a feeding wheel, the two brush shafts are installed with spiral rust removal brush sheets, the spiral rust removal brush sheets are in contact with the belt material, two cleaning wheels are rotatably connected between the inner surfaces of the frame, the two cleaning wheels are installed with first gears, the two first gears are meshed with each other, one of the feeding wheels is transmission-connected with a first belt, the other cleaning wheel is driven by the first belt, the two cleaning wheels are evenly distributed with rubber bristles, the rubber bristles are in contact with the belt material.

[0023] Furthermore, couplings are rotatably connected between the inner surfaces of the frame and corresponding to the positions directly above the two brush shafts, the tail ends of the two couplings are installed with linked bevel gears, the top ends of the two brush shafts are fixedly installed with driven bevel gears, the two driven bevel gears are respectively connected to the two linked bevel gears for transmission, a second belt is connected for transmission on one of the belt wheels, and the two couplings are driven by the second belt.

[0024] Furthermore, the spiral directions of the two spiral rust-removing brush pieces are opposite, the axis of the brush shaft is perpendicular to the axis of the feed wheel, and the axis of the cleaning wheel is parallel to the axis of the feed wheel.

[0025] The beneficial effect of adopting the above further scheme is that after the winding roller and the belt material wheel are driven, the linkage structure of the coupling shaft and the brush shaft is set, and then the two brush shafts are driven to rotate in the same direction at a set speed. When the two brush shafts rotate in the same direction at the set speed, the two spiral rust removal brushes are driven to perform spiral cleaning on the inner and outer surfaces of the strip, and the rust stains on the inner and outer surfaces of the strip are effectively removed by cleaning.

[0026] The spiral structure of the spiral rust removal brush can reciprocate and clean the inner and outer surfaces of the strip and quickly remove the rust stains, thereby effectively ensuring the rust removal strength and rust removal effect of the spiral rust removal brush on the strip.

[0027] By setting the layout direction of the cleaning wheel and the spiral rust removal brush, multi-directional cleaning of the strip surface can be achieved, and by setting the rubber bristles on the surface of the cleaning wheel, the residual rate of rust stains and dust on the strip surface can be effectively reduced, thereby ensuring the cleanliness of the strip surface and the yield rate of the strip during subsequent extrusion molding.

[0028] Further, the differential and reciprocating tensioning mechanism includes a tensioning frame and a reciprocating frame, two clamping wheels and a first differential shaft are rotatably connected between the inner surface of the frame, a first gap for clamping the strip is fixedly arranged between the two clamping wheels, second gears are installed on the sides of the two clamping wheels, and the two second gears are meshed with each other, one clamping wheel is connected to the first belt transmission, the reciprocating frame is slidably connected to the frame, a group of return springs are installed between the reciprocating frame and the frame, a third belt is connected to the first differential shaft for transmission, the third belt is connected to the belt material wheel for transmission, two first missing gears are installed on the first differential shaft, two first toothed plates are installed on the reciprocating frame, and the two first missing gears are respectively connected to the first toothed plates for transmission, two tensioning wheels are rotatably connected to the tensioning frame, a second gap for clamping the strip is fixedly arranged between the two tensioning wheels, a T-shaped pull rod is installed on the tensioning frame, the T-shaped pull rod is slidably connected to the reciprocating frame, and a tensioning spring limited by the reciprocating frame is sleeved on the T-shaped pull rod.

[0029] The beneficial effect of adopting the above-mentioned further scheme is that when in use, the two clamping wheels and the two tensioning wheels effectively clamp the strip. When the strip feeding wheel, the tensioning wheel and the clamping wheel rotate, the reciprocating frame is driven to reciprocate within a set stroke through the setting of the first differential shaft, the first missing gear, the first tooth plate, the return spring and the tensioning spring. After the reciprocating frame reciprocates within the set stroke, it drives the tensioning frame and the tensioning wheel to reciprocate within the set stroke. After the tensioning frame and the tensioning wheel reciprocate within the set stroke, the conveyed strip is reciprocated and tensioned. Through the cooperation of the tensioning spring, an elastic tensioning effect can be achieved when the strip is tensioned. By realizing the reciprocating tensioning effect of the strip, the wrinkles, curvature and structural stress on the surface of the strip can be fully removed. By removing the wrinkles, curvature and structural stress on the surface of the strip, the strip can be stably shaped in the subsequent extrusion molding process and the yield of the strip extrusion molding process can be effectively improved.

[0030] Further, the reciprocating ballast and forming mechanism includes a vibration pressure frame, the inner wall of the vibration pressure frame is slidably connected with a group of T-shaped pressure rods, the bottom end of each T-shaped pressure rod is installed with a pressure seat, the inner wall of each pressure seat is rotatably connected with an upper extrusion wheel, and a pressure relief spring is sleeved on each T-shaped pressure rod and corresponding to the position between the pressure seat and the vibration pressure frame.

A second differential shaft is rotatably connected between the inner surfaces of the frame, two second missing gears are installed on the second differential shaft, and the two second missing gears are respectively connected to the two second tooth plates in driving connection, and a fourth belt is connected to the second differential shaft in driving connection, and the fourth belt is connected to the clamping wheel in driving connection, and a lower extrusion wheel is rotatably connected between the inner surfaces of the frame and corresponding to the position directly below each upper extrusion wheel.

[0031] The beneficial effect of adopting the above-mentioned further scheme is that when the strip wheel rotates, the second differential shaft is driven. After the second differential shaft is driven, the second tooth plate, the second missing gear and the pressure relief spring are set to drive the vibration frame to reciprocate within the set stroke. After the vibration frame reciprocates within the set stroke, it drives a group of upper extrusion wheels to perform vibration pressing to form the strip. Through vibration pressing forming, the extrusion forming efficiency and extrusion strength of the strip are effectively improved.

[0032] Furthermore, the shaping mechanism includes a group of upper shaping wheels rotatably connected between the inner surfaces of the frame, and lower shaping wheels are rotatably connected between the inner surfaces of the frame and corresponding to the position directly below each upper shaping wheel. A discharging motor is installed on the side of the frame, and the output shaft end of the discharging motor is fixedly connected to one of the upper shaping wheels.

[0033] Furthermore, the axis of the T-shaped pull rod is parallel to the horizontal plane, and the axis of the T-shaped pressure rod is perpendicular to the horizontal plane.

[0034] Furthermore, a single chip microcomputer is installed on the frame.

[0035] The beneficial effects of the present invention are:

[0036] 1) The device can efficiently complete the non-cutting extrusion molding operation of the hollow frame of the display, and when the strip is extruded, the device can improve the yield of the hollow frame of the display during extrusion molding by pre-rust removal, pre-cleaning, pre-tensioning and vibration extrusion.

[0037] 2) In the present invention, after the winding roller and the material wheel are driven, the linkage structure of the coupling shaft and the brush shaft is set to drive the two brush shafts to rotate in the same direction at a set speed. When the two brush shafts rotate in the same direction at the set speed, the two spiral rust removal brushes are driven to perform spiral cleaning on the inner and outer surfaces of the strip. The rust stains on the inner and outer surfaces of the strip are effectively removed by brushing. The spiral structure of the spiral rust removal brush can reciprocately clean the inner and outer surfaces of the strip and quickly remove the rust stains, thereby effectively ensuring the rust removal strength and rust removal effect of the spiral rust removal brush on the strip. The layout direction of the cleaning wheel and the spiral rust removal brush can achieve multi-directional cleaning of the strip surface. The rubber bristles on the surface of the cleaning wheel can effectively reduce the residual rate of rust stains and dust on the strip surface, thereby ensuring the cleanliness of the strip surface and the yield rate of the strip during subsequent extrusion molding.

[0038] 3) When the present invention is in use, the two clamping wheels and the two tensioning wheels can effectively clamp the strip. When the strip wheel, the tensioning wheel and the clamping wheel rotate, the first differential shaft, the first missing gear, the first tooth plate, the reset spring and the tensioning spring are set to drive the reciprocating frame to move back and forth within the set stroke. After the reciprocating frame moves back and forth within the set stroke, it drives the tensioning frame and the tensioning wheel to move back and forth within the set stroke. After the tensioning frame and the tensioning wheel move back and forth within the set stroke, the conveyed strip is reciprocated and tensioned. Through the cooperation of the tensioning spring, an elastic tensioning effect can be achieved when the strip is tensioned. By realizing the reciprocating tensioning effect of the strip, the wrinkles, curvature and structural stress on the surface of the strip can be fully removed. By removing the wrinkles, curvature and structural stress on the surface of the strip, the strip can be stably shaped in the subsequent extrusion molding process and the yield of the strip in the extrusion molding process can be effectively improved.

After the second differential shaft is driven, the second tooth plate, the second missing gear and the pressure relief spring are set to drive the vibration frame to reciprocate within the set stroke. After the vibration frame reciprocates within the set stroke, it drives a group of upper extrusion wheels to perform vibration pressing to form the strip. Through vibration pressing forming, the extrusion forming efficiency and extrusion strength of the strip are effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The unwinding component includes a winding roller 3 rotatably connected to the frame 1, and an unwinding motor is installed on the surface of the frame 1. The winding roller 3 is driven by the unwinding motor. A rolled strip 2 is wound on the winding roller 3, and a cavity is opened inside the winding roller 3. A group of inner support bags 38 distributed in a circular array and cooperating with the rolled strip 2 are installed on the winding roller 3, and the inner cavity of each inner support bag 38 is connected to the cavity. A pressure control pump 4 is installed on the frame 1, and the port of the pressure control pump 4 is connected to the cavity through a pipeline. An air pressure probe is fixedly provided at the connection point between the pressure control pump 4 and the cavity. A plurality of belt wheels 5 are rotatably connected between the inner surface of the frame 1, and each belt wheel 5 is in contact with the strip 2. A transmission motor 6 is installed on the side of the frame 1, and the output shaft end of the transmission motor 6 is fixedly connected to a belt wheel 5.

[0055] When the strip 2 is extruded, the unwinding motor drives the winding roller 3 to rotate at a set speed. After the winding roller 3 rotates, the strip 2 is unwound at a set speed. When the rolled strip 2 is mounted on the winding roller 3, the inner support bag 38 is sufficiently pressurized. After the inner support bag 38 is sufficiently pressurized, the rolled strip 2 is effectively fixed on the winding roller 3.

[0056] When the belt wheel 5 rotates, the rotation speed of the belt wheel 5 is the same as the rotation speed of the winding roller 3;

[0057] When it is necessary to remove the unused coiled strip 2 from the reel 3 , the gas inside the inner support bag 38 is fully emptied. After the gas inside the inner support bag 38 is fully emptied, the unused coiled strip 2 can be quickly removed from the reel 3 .

[0058] Rust removal and pre-cleaning components, used for rust removal and pre-cleaning of the unwinding strip 2;

[0059] The rust removal and pre-cleaning components include two brush shafts 7 rotatably connected to the inner wall of the frame 1, and the two brush shafts 7 are driven by a belt wheel 5;

[0062] The spiral directions of the two spiral rust removal brush pieces 8 are opposite;

[0063] Two cleaning wheels 9 are rotatably connected between the inner surfaces of the frame 1, and first gears 10 are mounted on the two cleaning wheels 9, and the two first gears 10 mesh with each other;

[0064] The axis of the brush shaft 7 is perpendicular to the axis of the belt wheel 5, and the axis of the cleaning wheel 9 is parallel to the axis of the belt wheel 5;

[0065] A first belt is connected to a material wheel 5 , and a cleaning wheel 9 is driven by the first belt. Rubber bristles 11 are evenly distributed on the two cleaning wheels 9 , and the rubber bristles 11 fit closely with the belt 2 .

[0066] After the winding roller 3 and the belt wheel 5 are driven, the linkage structure of the coupling shaft 37 and the brush shaft 7 is set, and then the two brush shafts 7 are driven to rotate in the same direction at a set speed. When the two brush shafts 7 rotate in the same direction at the set speed, the two spiral rust removal brushes 8 are driven to perform spiral cleaning on the inner and outer surfaces of the strip 2, and the rust stains on the inner and outer surfaces of the strip 2 are effectively removed by cleaning.

[0067] The spiral structure of the spiral rust removal brush 8 can reciprocately clean the inner and outer surfaces of the strip 2 and quickly remove the rust stains, thereby effectively ensuring the rust removal strength and rust removal effect of the spiral rust removal brush 8 on the strip 2;

[0068] By setting the layout direction of the cleaning wheel 9 and the spiral rust removal brush 8, multi-directional cleaning of the surface of the strip 2 can be achieved, and by setting the rubber bristles 11 on the surface of the cleaning wheel 9, the residual rate of rust stains and dust on the surface of the strip 2 can be effectively reduced, thereby ensuring the cleanliness of the surface of the strip 2 and the yield rate of the strip 2 during subsequent extrusion molding.

[0069] Differential and reciprocating tensioning mechanism for tensioning the pay-out strip 2;

After the reciprocating frame 13 reciprocates within the set stroke, it drives the tensioning frame 12 and the tensioning wheel 20 to reciprocate within the set stroke. After the wheel 20 moves back and forth within the set stroke, it then reciprocates and tensions the conveyed strip 2. Through the cooperation of the tensioning spring 22, it can play an elastic tensioning effect when the strip 2 is tensioned. By realizing the reciprocating tensioning effect of the strip 2, the wrinkles, curvature and structural stress on the surface of the strip 2 can be fully removed. By removing the wrinkles, curvature and structural stress on the surface of the strip 2, the strip 2 can be stably shaped in the subsequent extrusion molding process and the yield of the strip 2 in the extrusion molding process can be effectively improved.

A lower extrusion wheel 34 is rotatably connected between the inner surfaces of the frame 1 and at a position corresponding to each upper extrusion wheel 33.

[0074] When the belt wheel 5 rotates, the second differential shaft 29 is driven. After the second differential shaft 29 is driven, the second toothed plate 28, the second missing gear 30 and the buffer spring 27 are set to drive the vibration frame 23 to reciprocate within the set stroke. After the vibration frame 23 reciprocates within the set stroke, it then drives a group of upper extrusion wheels to perform vibration-pressing forming on the strip 2. Through vibration-pressing forming, the extrusion forming efficiency and extrusion strength of the strip 2 are effectively improved.
