A fully automatic 57-roller reed straightening machine

Abstract

A fully automatic 57-roller reed straightening machine belongs to the technical field of reed straightening machine equipment. Through the mutual cooperation of a servo conveying motor, a worm, a swing arm, a slider, a pusher blade and a vertical feeding chute, the automatic supply of reeds can be realized, thus achieving the automatic leveling of reeds. The entire leveling process can be completed without manual operation. The automatic material collection effect is achieved through an automatic material collection mechanism. Since the thickness of the straightened reeds is different, the height of the pusher blade is adjusted by changing the thickness of the gasket. When the thickness of the reed changes, the height of the pusher blade can be adjusted simultaneously to ensure that the pusher blade can accurately push a single reed during movement. In the present invention, there are twenty-eight upper leveling rollers and twenty-nine lower leveling rollers, a total of fifty-seven leveling rollers. The roller diameter of each leveling roller needs to be set the same, achieving a straightening accuracy of 0.08 mm. The improvement of the reed accuracy enables the fabric to meet the requirements of high weaving density.

Description

Technical Field

[0001] The present invention belongs to the technical field of reed straightening machines, and particularly relates to a full-automatic 57-roller reed straightening machine. Background Art

[0002] A reed is a kind of textile machinery accessory which is a steel reed fitting with a special structure formed by punching a steel strip. It is widely used in the weaving process.

Detailed implementation manners

[0021] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0022] Embodiment: A fully automatic 57-roll reed blade straightening machine, as Figures 1-8As shown, it includes a straightening machine body and a reed conveying mechanism. The reed conveying mechanism includes a machine table and a feeding table. A servo conveying motor is provided on the lower side of the machine table.

A slide bar is horizontally arranged inside the feeding table. Both ends of the slide bar are fixed to the left and right sides inside the feeding table. A slider is slidably mounted on the slide bar. A swing arm is provided between the upper end on the right side of the slider and the worm. The servo conveying motor drives the worm to rotate, and the worm drives the swing arm to move left and right, causing the swing arm to push the slider to move left and right reciprocally. An opening is provided on the right side of the feeding table. The middle part of the swing arm passes through the opening. A traveling groove is provided in the middle of the upper side of the feeding table. A vertical feeding groove is provided above the traveling groove.

The left end of the feeding table is fixed to the upper right side of the straightening machine body. A straightening machine roll group frame is provided on the upper left side of the straightening machine body. The roll group frame includes a roll group frame base and a roll group main frame. The roll group main frame is arranged on the upper side of the roll group frame base. A lower leveling roll group base is horizontally arranged on the lower side inside the roll group main frame. The lower end of the lower leveling roll group base is fixedly connected to the roll group frame base. An upper leveling roll group base is horizontally arranged inside the roll group main frame and above the lower leveling roll group base. Twenty-nine lower leveling rolls are provided at the upper end of the lower leveling roll group base. Twenty-eight upper leveling rolls are provided at the lower end of the upper leveling roll group base. The lower leveling rolls and the upper leveling rolls are arranged in a vertically staggered manner. The lower leveling rolls and the lower leveling roll group base, and the upper leveling rolls and the upper leveling roll group base are all precisely rotatably connected. A driving motor is provided at the rear side inside the straightening machine body. A gear splitting box is provided on the upper side of the rear end of the straightening machine body. A main transmission wheel extends out from the right side of the gear splitting box. Inside the gear splitting box is a rotating mechanism that distributes the power input by the rotation of the main transmission wheel to fifty-seven rear universal couplings. The main transmission wheel and the driving motor are connected by a transmission belt. A rear universal coupling corresponding to the number of the lower leveling rolls and the upper leveling rolls extends out from the left side of the gear splitting box. Front universal couplings are provided at the rear ends of the lower leveling rolls and the upper leveling rolls. A universal connecting rod is provided between the rear universal coupling and the front universal coupling. A control box is provided on the front side of the straightening machine body. A PLC control module is installed inside the control box. A touch screen is provided on the upper surface of the control box. A switch button is provided on one side of the touch screen. The PLC control module, the touch screen, and the switch button are electrically connected.

[0023] The roll diameters of the lower flattening rollers and the upper flattening rollers are both φ7mm - φ7.5mm. The center distances between adjacent pairs of lower flattening rollers and between adjacent pairs of upper flattening rollers are both 7.17mm - 7.68mm. The roll diameters of the fifty-seven flattening rollers need to be unified and the same, achieving a straightening accuracy of 0.08mm for the reed blades. The improvement of the reed blade accuracy enables the fabric to meet the requirements of high weaving density; the effective length of the lower flattening rollers and the upper flattening rollers is 40mm, which can ensure the straightening of some special-shaped reed blades. The materials of the lower flattening rollers and the upper flattening rollers are high-carbon chromium bearing steel No. 2 quenched to HRC64 - 65, making the straightening accuracy of the present invention more stable after quenching.

[0024] Three positioning platforms are fixedly arranged on the front side of the base of the lower flattening roller group. Three dial indicators are arranged on the front side of the base of the upper flattening roller group. The dial indicators are fixed on the base of the upper flattening roller group. The end parts of the measuring rods of the three dial indicators respectively touch the upper surfaces of the three positioning platforms. The base of the upper flattening roller group is in precise sliding connection with the main frame of the roller group. The base of the upper flattening roller group is horizontally divided into three-section upper and lower adjustable pressing blocks. The three dial indicators are respectively fixed on the front sides of the three-section upper and lower adjustable pressing blocks. The twenty-eight upper flattening rollers are evenly arranged in the three-section upper and lower adjustable pressing blocks. Three adjusting lifting screws are respectively arranged corresponding to the three-section upper and lower adjustable pressing blocks. Three adjusting rotary disks are arranged on the front side of the upper end part of the main frame of the roller group. The rear ends of the three adjusting rotary disks are respectively in threaded rotational connection with the three adjusting lifting screws. By rotating the adjusting rotary disks, the adjusting rotary disks drive the adjusting lifting screws to rotate, so that the pressing blocks achieve the effect of moving up and down. This effect is based on the principle of the threaded lifting rod; when one of the pressing blocks is adjusted downward, the dial indicator fixed on the front side also moves downward accordingly. At this time, due to the limitation of the positioning platform for the measuring rod of the dial indicator, the downward movement amount of the dial indicator can be displayed on the dial. The user only needs to adjust the pressing force of the pressing block corresponding to the pointer on the dial indicator.

[0025] An unloading rack is arranged on the left side of the base of the roller group frame. Several unloading rollers are arranged in the middle of the unloading rack. The several unloading rollers are arranged with the left side lower and the right side higher. The unloading roller on the right side in the middle of the unloading rack is butted against the lower flattening roller. A vibration motor is arranged on the front side of the unloading rack. A receiving plate is arranged above the several unloading rollers and in the unloading rack. The right end of the receiving plate abuts against the rear side of the right end part of the unloading rack. The left end of the receiving plate inclines forward. A receiving block is arranged above the unloading rollers and on the left front side of the unloading rack. A horn-shaped receiving opening is arranged on the lower side of the right end of the receiving block. A small unloading opening is arranged on the lower side of the left end of the receiving block. The left end of the receiving plate is connected to the right rear side of the horn-shaped receiving opening; the reed blades straightened by the lower flattening rollers and the upper flattening rollers enter the unloading rollers after being output. The receiving plate gathers the reed blades entering the unloading rollers towards the horn-shaped receiving opening, so that each reed blade can be output from the small unloading opening. The vibration motor can enable the output reed blades to pass through the small unloading opening smoothly.

[0026] An automatic material collecting mechanism is provided on the left side of the straightening machine body. The automatic material collecting mechanism includes a lifting assembly and a lateral movement assembly. The lifting assembly is installed at the left rear side of the straightening machine body, and the lateral movement assembly is installed at the upper end of the lifting assembly. A material collecting frame is provided at the right end of the lateral movement assembly. A number of material collecting grooves are provided in the material collecting frame, and material collecting boxes for receiving reed blades are placed in the material collecting grooves. The openings of the material collecting grooves face rightward. The straightened reed blades are output from the small discharge port. Controlled by the PLC control module, the bottom of the material collecting box is aligned with the small discharge port by the up and down movement of the lifting assembly. When the reed blades are output, the reed blades will fill the material collecting box more and more. At this time, the lifting assembly slowly moves downward until the material collecting box is filled with reed blades. When the number of reed blades collected fills a material collecting box through control, the lateral movement assembly quickly moves to align the material collecting box without reed blades with the small discharge port, achieving the effect of automatic material collection.

[0027] An infrared material detector is installed at the lower end of the vertical feeding groove, and a stepless speed change switch is installed outside the servo conveying motor. The servo conveying motor, the infrared material detector, the driving motor and the automatic material collecting mechanism are all controlled by the control box. The infrared material detector can detect and record the number of reed blades pushed out by the pushing blade in the vertical feeding groove, and this number is displayed on the touch screen display. The stepless speed change switch can control the rotation speed of the servo conveying motor, thereby controlling the conveying speed of the reed blades.

[0028] The lower end of the pushing blade is assembled and connected to the slider by bolts, and a number of gaskets are padded on the lower side of the pushing blade. The number of gaskets is composed of gaskets with equal thickness or different thicknesses. Since the thicknesses of the straightened reed blades are different, the height of the pushing blade also needs to be correspondingly matched. The height of the pushing blade is adjusted by changing the thickness of the gaskets. When the thickness of the reed blades changes, the height of the pushing blade can also be adjusted simultaneously to ensure that the pushing blade can accurately push a single reed blade during movement.

[0029] The operating principle of the present invention:

[0030] Put the number of unstraightened reed blades into the vertical feeding chute. Due to gravity, the reed blades will move downward by themselves. The infinitely variable speed switch adjusts and controls the rotation speed of the servo conveying motor. The servo conveying motor drives the worm to rotate, and the worm drives the swing arm to move left and right, causing the swing arm to push the slider to move left and right reciprocally. The slider synchronously drives the pushing blade. The pushing blade moves reciprocally in the traveling chute, and the top of the pushing blade also moves reciprocally in the mating chute, so that each time the pushing blade moves, it pushes a single reed blade to move upward between the upper leveling roller and the lower leveling roller. The infrared material detector can detect and record the number of reed blades pushed out by the pushing blade in the vertical feeding chute, and this number is displayed on the touch screen. The operator rotates the adjustment dial, and the adjustment dial drives the adjustment lifting screw to rotate, causing the pressure block to move up and down. When one of the pressure blocks is adjusted downward, the fixed dial indicator on the front side also moves downward. At this time, due to the limit of the positioning table on the measuring rod of the dial indicator, the downward movement amount of the dial indicator can be displayed on the table. The user only needs to adjust the pressing force of the pressure block according to the pointer on the dial indicator. The pressing force of the rightmost pressure block in the three-stage up-and-down adjustable pressure block is the largest, causing the reed blade to bend first. The pressing force of the middle pressure block in the three-stage up-and-down adjustable pressure block is less than the pressing force of the right pressure block. The pressing force of the left pressure block in the three-stage up-and-down adjustable pressure block is zero, achieving the effect of straightening the bent reed blade again. The straightened reed blades enter the discharging roller, and the receiving plate gathers the reed blades entering the discharging roller towards the trumpet-shaped receiving opening, so that each reed blade can be output from the small discharging opening. The vibration motor enables the output reed blades to smoothly pass through the small discharging opening, and the straightened reed blades are output from the small discharging opening. Controlled by the PLC control module, by controlling the up-and-down movement of the lifting assembly, the bottom of the receiving box is aligned with the small discharging opening. When the reed blades are output, the reed blades will fill the receiving box more and more. At this time, the lifting assembly slowly moves downward until the receiving box is filled with reed blades. When the number of reed blades collected fills a receiving box through control, the lateral movement assembly moves quickly, aligning the receiving box without reed blades with the small discharging opening, achieving the effect of automatic material collection.

[0031] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention should be considered as belonging to the protection scope of the present invention.
