Description

Technical Field

[0001] This invention relates to the field of molding equipment technology, specifically to a non-cutting extrusion molding equipment for a hollow display frame. Background Technology

[0002] In the production process of LCD TVs, the thin LCD screen is encased in a metal frame to ensure its resistance to bending and its stability. Currently, this metal frame is manufactured through stamping. Because the metal frame uses sheet metal as its base material, a large piece of material in the middle of the frame is generated as scrap during production. This significantly increases production costs, thereby increasing consumer spending and resulting in substantial resource waste.

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

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

[0005] 2: Cut a "V" shaped opening in the long strip of metal profile B according to the set dimensions;

[0006] 3: Fold four "V" shapes to form an outer frame;

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

[0008] 5: Surface treatment.

[0009] The above method uses long strip metal material to form the outer frame of the liquid crystal display screen, which does not generate any material waste. Since no waste is generated in each processing step, the production cost is greatly reduced. However, the existing technology lacks a non-cutting extrusion molding equipment suitable for the production of hollow display frames. Moreover, the existing molding equipment is not convenient to improve the yield of hollow display frames during extrusion molding through pre-rust removal, pre-cleaning, pre-tensioning and vibratory extrusion. Based on this, the present invention provides a non-cutting extrusion molding equipment for hollow display frames to solve the problems mentioned in the background technology. Summary of the Invention

[0010] This invention addresses the technical problems existing in the prior art by providing a non-cutting extrusion molding equipment for display hollow frames. This solves the problem that existing molding equipment is not convenient for improving the yield of display hollow frames during extrusion molding through multiple methods such as pre-rust removal, pre-cleaning, pre-tensioning, and vibratory extrusion.

[0011] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A non-cutting extrusion molding equipment for display hollow frames, comprising a frame, and further comprising:

[0012] Unwinding components are used for the continuous unwinding of strip.

[0013] Rust removal and pre-cleaning components are used for rust removal and pre-cleaning of the strip material.

[0014] Differential and reciprocating tensioning mechanism, used to release the tension of the strip;

[0015] A reciprocating ballast and forming mechanism is used for extruding and forming strips.

[0016] A shaping mechanism is used to shape extruded strips.

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

[0018] Furthermore, the unwinding component includes a roll rotatably connected to the frame, an unwinding motor mounted on the surface of the frame, the roll being driven by the unwinding motor, a coiled strip wound on the roll, a cavity being formed inside the roll, a set of inner support bladders arranged in a circumferential array and cooperating with the coiled strip being mounted on the roll, the inner cavity of each inner support bladder communicating with the cavity, a pressure control pump mounted on the frame, the port of the pressure control pump communicating with the cavity through a pipe, a pressure probe being fixedly installed at the communication point between the pressure control pump and the cavity, multiple strip rollers rotatably connected between the inner surfaces of the frame, each strip roller being in contact with the strip, a drive motor mounted on the side of the frame, the output shaft end of the drive motor being fixedly connected to one of the strip rollers.

[0019] The beneficial effect of adopting the above-mentioned further solution is that when the strip extrusion molding operation is performed, the unwinding motor drives the winding roller to rotate at a set speed. After the winding roller rotates, it drives the strip to be released at a set speed. When the coiled strip is installed on the winding roller, the inner support bladder is fully pressurized. After the inner support bladder is fully pressurized, the coiled strip is effectively fixed on the winding roller.

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

[0021] When it is necessary to remove unused coiled strip from the winding roll, the gas inside the inner support bladder is fully emptied. Once the gas inside the inner support bladder is fully emptied, it facilitates the rapid removal of the unused coiled strip from the winding roll.

[0022] Furthermore, the rust removal and pre-cleaning component includes two brush shafts rotatably connected to the inner wall of the frame. Both brush shafts are driven by a feed wheel. Spiral rust removal brush blades are installed on both brush shafts and are in contact with the strip. Two cleaning wheels are rotatably connected between the inner surfaces of the frame. A first gear is installed on each of the two cleaning wheels and the two first gears mesh with each other. A first belt is driven to one of the feed wheels, and the cleaning wheel is driven by the first belt. Rubber bristles are evenly distributed on both cleaning wheels and are adapted to fit the strip.

[0023] Furthermore, the inner surfaces of the frame are rotatably connected to each other and to the positions directly above the two brush shafts. The tail ends of the two couplings are equipped with linkage bevel teeth, and the top ends of the two brush shafts are fixedly equipped with driven bevel teeth. The two driven bevel teeth are respectively connected to the two linkage bevel teeth. A second belt is connected to one of the material pulleys, and the two couplings are driven by the second belt.

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

[0025] The beneficial effect of adopting the above-mentioned further solution is that after the roll and the strip wheel are driven, the two brush shafts are driven to rotate in the same direction at a set speed through the linkage structure of the coupling and the brush shaft. When the two brush shafts rotate in the same direction at a set speed, they drive the two spiral rust removal brushes to perform spiral cleaning on the inner and outer surfaces of the strip. Through cleaning, the rust stains on the inner and outer surfaces of the strip are effectively removed.

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

[0027] By setting the layout direction of the cleaning wheel and spiral rust removal brush, multi-directional cleaning of the strip surface can be achieved. Furthermore, the rubber bristles on the surface of the cleaning wheel can effectively reduce the residual rate of rust 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.

[0028] Furthermore, the differential and reciprocating tensioning mechanism includes a tensioning frame and a reciprocating frame. Two clamping rollers and a first differential shaft are rotatably connected between the inner surfaces of the frame. A first clamping slot for clamping the strip is fixedly provided between the two clamping rollers. A second gear is installed on the side of each of the two clamping rollers, and the two second gears mesh with each other. One clamping roller is driven by a first belt. The reciprocating frame is slidably connected to the frame. A set of return springs is installed between the reciprocating frame and the frame. A third belt is driven by the first differential shaft, and the third belt is driven by a belt pulley. 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 driven by the first toothed plates respectively. Two tensioning rollers are rotatably connected to the tensioning frame. A second clamping slot for clamping the strip is fixedly provided between the two tensioning rollers. A T-shaped tie rod is installed on the tensioning frame, and the T-shaped tie rod is slidably connected to the reciprocating frame. A tensioning spring that is limited by the reciprocating frame is sleeved on the T-shaped tie rod.

[0029] The beneficial effect of adopting the above-mentioned further solution is that, during use, both clamping rollers and two tensioning rollers effectively clamp the strip. When the strip roller, tensioning roller, and clamping roller 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 toothed plate, the return spring, and the tensioning spring. After the reciprocating frame reciprocates within the set stroke, it then drives the tensioning frame and tensioning roller to reciprocate within the set stroke. After the tensioning frame and tensioning roller reciprocate within the set stroke, they then reciprocate to tension the conveyed strip. With 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, wrinkles, bends, and structural stresses on the surface of the strip are fully removed. By removing wrinkles, bends, and structural stresses 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.

[0030] Furthermore, the reciprocating pressure and forming mechanism includes a vibratory pressing frame. A set of T-shaped pressure rods are slidably connected to the inner wall of the vibratory pressing frame. A pressure seat is installed at the bottom end of each T-shaped pressure rod. An upper extrusion wheel is rotatably connected to the inner wall of each pressure seat. A pressure-relieving spring is sleeved on each T-shaped pressure rod at a position corresponding to the pressure seat and the vibratory pressing frame. Two guide posts and two second toothed plates are respectively installed on the surface of the vibratory pressing frame. The two guide posts are slidably connected to the 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. The two second missing gears are respectively drivenly connected to the two second toothed plates. A fourth belt is drivenly connected to the second differential shaft. The fourth belt is drivenly connected to a clamping wheel. A lower extrusion wheel is rotatably connected between the inner surfaces of the frame at a position directly below each upper extrusion wheel.

[0031] The beneficial effect of adopting the above-mentioned further solution is that when the strip wheel rotates, the second differential shaft is driven. After the second differential shaft is driven, through the setting of the second toothed plate, the second missing gear and the pressure relief spring, the vibratory pressing frame is driven to reciprocate within the set stroke. After the vibratory pressing frame reciprocates within the set stroke, it then drives a set of upper extrusion rollers to vibrate and press the strip to form. Through vibratory pressing, the extrusion forming efficiency and extrusion strength of the strip are effectively improved.

[0032] Furthermore, the shaping mechanism includes a set of upper shaping wheels rotatably connected between the inner surfaces of the frame, and lower shaping wheels rotatably connected between the inner surfaces of the frame and at positions directly below each upper shaping wheel. A discharge motor is mounted on the side of the frame, and the output shaft end of the discharge motor is fixedly connected to one of the upper shaping wheels.

[0033] Furthermore, the axis of the T-shaped tie 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 microcontroller is mounted on the rack.

[0035] The beneficial effects of this invention are:

[0036] 1) This device can efficiently complete the non-cutting extrusion molding of the hollow frame of the display. When the strip is extruded, this device can improve the yield of the hollow frame of the display through pre-rust removal, pre-cleaning, pre-tensioning and vibratory extrusion.

[0037] 2) In this invention, after the roller and the strip wheel are driven, the two brush shafts are driven to rotate in the same direction at a set speed through the linkage structure of the coupling and the brush shaft. When the two brush shafts rotate in the same direction at the set speed, they drive the two spiral rust removal brushes to perform spiral cleaning on the inner and outer surfaces of the strip. Through cleaning, the rust stains on the inner and outer surfaces of the strip are effectively removed. Through the spiral structure of the spiral rust removal brushes, the inner and outer surfaces of the strip can be cleaned repeatedly and the cleaned rust stains can be quickly carried out, thereby effectively ensuring the rust removal strength and rust removal effect of the spiral rust removal brushes on the strip. Through the arrangement direction of the cleaning wheel and the spiral rust removal brushes, multi-directional cleaning of the strip surface can be achieved. Furthermore, through 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.

[0038] 3) When this invention is used, both clamping rollers and two tensioning rollers effectively clamp the strip. When the strip roller, tensioning roller, and clamping roller 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 toothed plate, the return spring, and the tensioning spring. After the reciprocating frame reciprocates within the set stroke, it then drives the tensioning frame and tensioning roller to reciprocate within the set stroke. After the tensioning frame and tensioning roller reciprocate within the set stroke, they then reciprocate and tension the conveyed strip. With 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, wrinkles, bends, and structural stresses on the surface of the strip are fully removed. By removing wrinkles, bends, and structural stresses 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.

[0039] 4) In this invention, when the strip wheel rotates, the second differential shaft is driven. After the second differential shaft is driven, the vibration pressing frame is driven to reciprocate within a set stroke by the setting of the second toothed plate, the second missing gear and the pressure relief spring. After the vibration pressing frame reciprocates within the set stroke, it then drives a set of upper extrusion rollers to vibrate and press the strip to form. Through vibration and pressing, the extrusion forming efficiency and extrusion strength of the strip are effectively improved. Attached Figure Description

[0050] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0051] The present invention provides the following preferred embodiments.

[0052] like Figure 1-8 As shown, a non-cutting extrusion molding device for a display hollow frame includes a frame 1, on which a microcontroller 31 is mounted, and further includes:

[0053] Unwinding component, used for continuous unwinding of strip 2;

[0054] The unwinding component includes a roll 3 rotatably connected to the frame 1. An unwinding motor is mounted on the surface of the frame 1. The roll 3 is driven by the unwinding motor. A coiled strip 2 is wound on the roll 3. A cavity is opened inside the roll 3. A set of inner support bladders 38 arranged in a circumferential array and cooperating with the coiled strip 2 are mounted on the roll 3. The inner cavity of each inner support bladder 38 is connected to the cavity. A pressure control pump 4 is mounted on the frame 1. The port of the pressure control pump 4 is connected to the cavity through a pipe. A pressure probe is fixedly installed at the connection between the pressure control pump 4 and the cavity. Multiple strip rollers 5 are rotatably connected between the inner surfaces of the frame 1. Each strip roller 5 is in contact with the strip 2. A drive motor 6 is mounted on the side of the frame 1. The output shaft end of the drive motor 6 is fixedly connected to a strip roller 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, it drives the strip 2 to be released at a set speed. When the coiled strip 2 is installed on the winding roller 3, the inner support bladder 38 is fully pressurized. After the inner support bladder 38 is fully pressurized, the coiled strip 2 is effectively fixed on the winding roller 3.

[0056] When the conveyor belt 5 rotates, the rotation speed of the conveyor belt 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 winding roller 3, the gas inside the inner support bladder 38 is fully emptied. After the gas inside the inner support bladder 38 is fully emptied, it is then convenient for the unused coiled strip 2 to be quickly removed from the winding roller 3.

[0058] Rust removal and pre-cleaning components are used for rust removal and pre-cleaning of 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 both brush shafts 7 are driven by a material wheel 5;

[0060] A coupling 37 is rotatably connected between the inner surfaces of the frame 1 and at the position directly above the two brush shafts 7. The tail ends of the two couplings 37 are equipped with linkage bevel teeth, and the top ends of the two brush shafts 7 are fixedly equipped with driven bevel teeth. The two driven bevel teeth are respectively connected to the two linkage bevel teeth. A second belt is connected to the material wheel 5 for transmission. The two couplings 37 are driven by the second belt.

[0061] Spiral rust-removing brushes 8 are installed on both brush shafts 7, and the spiral rust-removing brushes 8 are in contact with the strip 2;

[0062] The two spiral rust-removing brushes 8 have opposite spiral directions;

[0063] Two cleaning wheels 9 are rotatably connected between the inner surfaces of the frame 1. Each of the two cleaning wheels 9 is equipped with a first gear 10, 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 conveyor belt 5, and the axis of the cleaning wheel 9 is parallel to the axis of the conveyor belt 5.

[0065] A first belt is connected to a material belt wheel 5, and a cleaning wheel 9 is driven by the first belt. Both cleaning wheels 9 are evenly covered with rubber bristles 11, which are adapted to fit the material belt 2.

[0066] After the roller 3 and the strip wheel 5 are driven, the two brush shafts 7 are driven to rotate in the same direction at a set speed through the linkage structure of the coupling 37 and the brush shaft 7. When the two brush shafts 7 rotate in the same direction at a 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. Through cleaning, the rust stains on the inner and outer surfaces of the strip 2 are effectively removed.

[0067] By using the spiral structure of the spiral rust removal brush 8, the inner and outer surfaces of the strip 2 can be repeatedly brushed and the rust stains brushed off can be quickly removed, 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. Furthermore, the rubber bristles 11 on the surface of the cleaning wheel 9 can effectively reduce the residual rate of rust stains and dust on the surface of the strip 2, 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, used to release the tension of strip 2;

[0070] The differential and reciprocating tensioning mechanism includes a tensioning frame and a reciprocating frame 13. Two clamping rollers 14 and a first differential shaft 15 are rotatably connected between the inner surfaces of the frame 1. A first clamping slot for holding the strip 2 is fixedly provided between the two clamping rollers 14. A second gear 16 is installed on the side of each of the two clamping rollers 14, and the two second gears 16 mesh with each other. One clamping roller 14 is connected to a first belt drive. The reciprocating frame 13 is slidably connected to the frame 1. A set of return springs 17 is installed between the reciprocating frame 13 and the frame 1. A third belt is drivenly connected to the first differential shaft 15. The third belt is connected to a belt pulley 5 for transmission. Two first missing gears 18 are installed on the first differential shaft 15. Two first toothed plates 19 are installed on the reciprocating frame 13. The two first missing gears 18 are respectively connected to the first toothed plates 19 for transmission. Two tensioning wheels 20 are rotatably connected on the tensioning frame. A second clamping gap for clamping the strip 2 is fixedly provided between the two tensioning wheels 20. A T-shaped tie rod 21 is installed on the tensioning frame. The T-shaped tie rod 21 is slidably connected to the reciprocating frame 13. A tensioning spring 22 that is limited by the reciprocating frame 13 is sleeved on the T-shaped tie rod 21.

[0071] In use, both clamping rollers 14 and two tensioning rollers 20 effectively clamp the strip 2. When the strip roller 5, tensioning roller 20, and clamping roller 14 rotate, the first differential shaft 15, the first gear 18, the first toothed plate 19, the return spring 17, and the tension spring 22 drive the reciprocating frame 13 to reciprocate within a set stroke. After the reciprocating frame 13 reciprocates within the set stroke, it then drives the tensioning frame and tensioning roller 20 to reciprocate within the set stroke. After reciprocating within the set stroke, the conveyed strip 2 is then reciprocated and tensioned. With the cooperation of the tension spring 22, the strip 2 can achieve an elastic tensioning effect when tensioned. By realizing the reciprocating tensioning effect of the strip 2, wrinkles, bends and structural stresses on the surface of the strip 2 are fully removed. By removing wrinkles, bends and structural stresses 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.

[0072] A reciprocating ballast and forming mechanism is used for extruding and forming the strip 2;

[0073] The reciprocating pressure and forming mechanism includes a vibratory pressure frame 23. A set of T-shaped pressure rods 24 are slidably connected to the inner wall of the vibratory pressure frame 23. Each T-shaped pressure rod 24 has a pressure seat 25 installed at its bottom end. Each pressure seat 25 has an upper extrusion wheel 33 rotatably connected to its inner wall. Each T-shaped pressure rod 24 is fitted with a pressure relief spring 27 at the position corresponding to the pressure seat 25 and the vibratory pressure frame 23. Two guide posts and two second toothed plates 28 are respectively installed on the surface of the vibratory pressure frame 23. The two guide posts are slidably connected to the frame 1. A second differential shaft 29 is rotatably connected between the inner surfaces of the frame 1. Two second gears 30 are installed on the second differential shaft 29. The two second gears 30 are respectively connected to the two second toothed plates 28. A fourth belt is connected to the second differential shaft 29. The fourth belt is connected to a clamping wheel 14. A lower extrusion wheel 34 is rotatably connected between the inner surfaces of the frame 1 at the position directly below each upper extrusion wheel 33.

[0074] When the belt roller 5 rotates, the second differential shaft 29 is driven. After the second differential shaft 29 is driven, through the setting of the second toothed plate 28, the second missing gear 30 and the pressure relief spring 27, the vibratory pressing frame 23 is driven to reciprocate within the set stroke. After the vibratory pressing frame 23 reciprocates within the set stroke, it then drives a set of upper extrusion rollers to vibrate and press the strip 2 to form. Through vibratory pressing, the extrusion forming efficiency and extrusion strength of the strip 2 are effectively improved.

[0075] The shaping mechanism is used to shape the extruded strip 2.

[0076] The shaping mechanism includes a set of upper shaping wheels 35 rotatably connected between the inner surfaces of the frame 1. Lower shaping wheels 36 are rotatably connected between the inner surfaces of the frame 1 and at positions directly below each upper shaping wheel 35. A discharge motor 32 is mounted on the side of the frame 1, and the output shaft end of the discharge motor 32 is fixedly connected to an upper shaping wheel 35.

[0077] The axis of the T-shaped tie rod 21 is parallel to the horizontal plane, and the axis of the T-shaped compression rod 24 is perpendicular to the horizontal plane.
