Description

Technical Field

[0001] This application relates to the field of heavy material unloading technology, and in particular to a heavy tension unloading device. Background Technology

[0002] In the feeding process of heavy materials such as cables, steel strips and composite materials, the structure of the fixed material tray is mostly rigid and can only be used for material trays of a single diameter. When changing to different specifications of materials, the mechanical structure needs to be manually adjusted, which is time-consuming, has low precision, and is prone to tension fluctuations. Tension control is mostly achieved by adjusting the motor speed or magnetic powder brake, but the impact of changes in the material tray diameter on tension transmission efficiency is not considered. When a small-diameter material tray rotates at high speed, the inertial torque is significantly reduced, and traditional control methods are prone to tension overload or relaxation.

[0003] Therefore, in response to the above problems, the applicant provides a heavy-duty tension discharge device. Summary of the Invention

[0004] In order to solve the problems mentioned in the background art, this application provides a heavy-duty tension unloading device.

[0005] This application provides a heavy-duty tension discharge device, which adopts the following technical solution:

[0006] A heavy-duty tension feeding device includes a turntable with a telescopic mechanism. The telescopic mechanism includes a multi-stage electric push rod. The output end of the multi-stage electric push rod is fixedly connected to a fixed rod. The fixed rod is fixedly connected to a sleeve. The sleeve is fixedly connected to a perforated plate. The perforated plate is rotatably connected to a connecting rod. Both ends of the connecting rod are fixedly connected to double plates. The double plates are located on a double-hole positioning plate. The double-hole positioning plate is fixedly connected to a positioning rod.

[0007] Optionally, it also includes a base, with corner connecting blocks fixedly connected to each of the four corners of the base. One end of a hydraulic shock absorber is fixedly connected to the bottom of each corner connecting block, and the other end of the hydraulic shock absorber is fixedly connected to the top of the fixed frame.

[0008] Optionally, each of the four fixed frames has a slider formed thereon, and a bolt runs horizontally through the bottom of the fixed frame. A sliding groove is slidably connected in the slider, and the sliding groove is formed at the top of the insert block.

[0009] Optionally, the insert block has horizontally opened insertion holes, which are evenly distributed from top to bottom. The bolt is inserted into one of the insertion holes. The bottom of the insert block is fixedly connected to a contact plate. The fixed frame, bolt, insert block and contact plate are combined to form a lifting assembly.

[0010] Optionally, it also includes a servo motor, with the servo motor fixedly connected to the bottom of the base. The rotating shaft of the servo motor is connected to the inside of the reducer through a flange. The rotating shaft of the reducer is fixedly connected to a turntable, and a hydraulic brake system is installed on the drive shaft of the turntable.

[0011] Optionally, a hole is provided at the center of the turntable, and the input end of a multi-stage electric push rod is fixedly connected to the hole. The turntable has multiple sliding grooves arranged in a circular array with the center point of the hole as the center, and a sliding seat is slidably connected to each of the multiple holes.

[0012] Optionally, each of the multiple slides is fixedly connected to a positioning rod, which contacts the inner wall of the material tray. The positioning rod has multiple holes evenly spaced from top to bottom, and each of the multiple holes is fixedly connected to a pressure sensor. Each of the multiple pressure sensors is electrically connected to a signal acquisition module and a processing module. The sleeve, perforated plate, double plate, connecting rod, double-hole positioning plate, positioning rod, pressure sensor and slide are combined to form a telescopic assembly.

[0013] Optionally, the outer circumferential wall of the sleeve is fixedly connected with multiple perforated plates in a ring array. The multiple perforated plates are rotatably connected to a connecting rod, which is fixedly connected to both ends of the double plates. Another connecting rod is rotatably connected to the double-hole positioning plate.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This invention uses the lifting and lowering of multi-stage electric push rods to drive the fixed rod and sleeve to lift and lower synchronously, and the slide block slides in a straight line in the first slide groove. The slide block drives the positioning rod to move closer or disperse along the direction of the first slide groove towards the direction of the multi-stage electric push rod. Multiple connecting rods pull the positioning rod to gather or disperse, thereby flexibly and quickly adjusting and adapting to the placement of material trays of different diameters in the positioning rod.

[0016] 2. In this invention, when the material tray and the positioning rod contact surface become loose during the high-speed rotation of the telescopic component driven by the turntable, the pressure sensor feeds back to the controller, which then controls the multi-stage electric push rod to stop operating. This prevents the material tray from having stable tension and avoids the material tray from rubbing against each other after becoming loose, thus affecting the quality of the product.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] This application discloses a heavy-duty tension feeding device.

[0027] like Figure 1-7 As shown, a heavy-duty tension feeding device includes a turntable 5, on which a telescopic mechanism is provided. The telescopic mechanism includes a multi-stage electric push rod 6. The output end of the multi-stage electric push rod 6 is fixedly connected to a fixed rod 60. The fixed rod 60 is fixedly connected to a sleeve 70. The sleeve 70 is fixedly connected to a perforated plate 71. The perforated plate 71 is rotatably connected to a connecting rod 73. The two ends of the connecting rod 73 are fixedly connected to double plates 72. The double plates 72 are located on a double-hole positioning plate 74. The double-hole positioning plate 74 is fixedly connected to a positioning rod 75.

[0028] Please see Figure 5 It also includes a base 1, and corner connecting blocks 2 are fixedly connected to the four corners of the base 1. One end of a hydraulic shock absorber 3 is fixedly connected to the bottom of the corner connecting block 2, and the other end of the hydraulic shock absorber 3 is fixedly connected to the top of the fixed frame 40. The hydraulic shock absorbers 3 at the four corners of the base 1 play a role in shock absorption and buffering during heavy operations.

[0029] Please see Figure 5 and Figure 6 Each of the four fixed frames 40 has a slider 400 formed thereon. A bolt 41 is horizontally inserted through the bottom of the fixed frame 40. A groove 420 is slidably connected in the slider 400. The groove 420 is formed at the top of the insert block 42.

[0030] Please see Figure 6 The insert block 42 has horizontally opened insertion holes 421, which are evenly distributed from top to bottom. The screw of the bolt 41 is inserted into one of the insertion holes 421. The bottom of the insert block 42 is fixedly connected to a contact plate 43. The fixed frame 40, bolt 41, insert block 42 and contact plate 43 are combined to form a lifting assembly 4. When the contact plate 43 is on a pit or raised ground, the insert block 42 can be slid up and down in the slider 400, and then the bolt 41 is inserted into one of the insertion holes 421 and tightened. This will make the base 1 supported by the four fixed frames 40 in a horizontal state, thus avoiding the tilting of the base 1 during placement. The operator can measure the horizontal state of the base 1 with a level.

[0031] Please see Figure 3 and Figure 5 The system also includes a servo motor. The base 1 has a servo motor fixedly connected to its bottom. The rotating shaft of the servo motor is connected to the inside of the reducer via a flange. The rotating shaft of the reducer is fixedly connected to a turntable 5. A hydraulic braking system is installed on the drive shaft of the turntable 5. The above-mentioned device is not shown in the attached drawings of the specification. Its working process is as follows: After the servo motor starts, it inputs high speed and low torque to the reducer through the flange connection. The reducer reduces the speed through gear meshing and amplifies the torque at the same time. The output shaft of the reducer is directly fixed to the turntable 5, driving it to rotate at low speed and high torque to realize material feeding or processing. Its braking process is as follows: When the system detects an abnormality such as tension over-limit, emergency stop signal or power failure, the hydraulic braking system receives the signal and starts. The hydraulic cylinder pushes the piston, causing the brake pads to press against the brake disc on the drive shaft of the turntable 5. A braking torque is generated through friction. The turntable 5 stops rotating quickly under the action of the braking torque to prevent material loosening or equipment damage.

[0032] Please see Figure 3 and Figure 4 The turntable 5 has a hole 51 at its center, and the input end of the multi-stage electric push rod 6 is fixedly connected to the hole 51. The turntable 5 has multiple sliding grooves 50 arranged in a circular array with the center point of the hole 51 as the center. Sliding seats 77 are slidably connected to the multiple holes 51.

[0033] Please see Figure 4Each of the multiple slide blocks 77 has a positioning rod 75 fixedly connected to its top. The positioning rod 75 contacts the inner wall of the material tray 8. The positioning rod 75 has multiple holes 750 evenly spaced from top to bottom. Each of the multiple holes 750 has a pressure sensor 76 fixedly connected to it. Each of the multiple pressure sensors 76 is electrically connected to a signal acquisition module and a processing module. The sleeve 70, the perforated plate 71, the double plate 72, the connecting rod 73, the double-hole positioning plate 74, the positioning rod 75, the pressure sensor 76, and the slide block 77 are combined to form a telescopic assembly 7. A signal acquisition and processing module is provided. This module is connected to each pressure sensor 76 through wires to collect the pressure signals transmitted by the pressure sensors 76 and convert them into digital signals. At the same time, a wireless transmission module is provided, which is connected to the signal acquisition module and the signal processing module to wirelessly send the processed data to the controller of the equipment. The controller then controls the extension and retraction of the multi-stage electric push rod 6.

[0034] Please see Figure 2 and Figure 4 The outer circumferential wall of the sleeve 70 is fixedly connected with a plurality of perforated plates 71 in a ring array. The plurality of perforated plates 71 are rotatably connected to a connecting rod 73. The connecting rod 73 is fixedly connected to both ends of the double plate 72. Another connecting rod 73 is rotatably connected to a double-hole positioning plate 74.

[0035] The implementation principle of a heavy-duty tension unloading device according to an embodiment of this application is as follows:

[0036] The slide block 77 slides in a straight line in the slide groove 50, thereby driving the positioning rod 75 to move towards or disperse along the direction of the slide groove 50 towards the multi-stage electric push rod 6.

[0037] The lifting and lowering of the multi-stage electric push rod 6 drives the fixed rod 60 and the sleeve 70 to lift and lower synchronously. Multiple connecting rods 73 pull the positioning rod 75 to gather or disperse, thereby adapting to the material trays 8 of different diameters and placing them in the positioning rod 75.

[0038] During the high-speed rotation of the turntable 5 and the telescopic component 7, when the contact surface between the material tray 8 and the positioning rod 75 becomes loose, the pressure sensor 76 transmits the signal to the signal acquisition and processing module via the wireless transmission module. The processing module then transmits the signal to the controller, which controls the multi-stage electric push rod 6 to lift and lower the sleeve 70. When the value transmitted by the pressure sensor 76 matches the set value, the controller controls the multi-stage electric push rod 6 to stop operating, thereby preventing the material tray 8 from having stable tension and preventing the material trays 8 from rubbing against each other after loosening, which would affect the quality of the product.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
