Description

Technical Field

[0001] The invention relates to the technical field of wrapping packaging machines, and in particular to a composite wrapping packaging machine chassis load-bearing system and a working method. Background Art

[0002] In the prior art, the through-type single-head tugboat load-bearing structure adopts a centripetal force design, and its structural form consists of an inner ring, an outer ring, a rim, a bearing, a bearing core, etc., and the inner ring and the outer ring are made of nylon. This existing structure has relatively complex requirements for the site and assembly process, and is not suitable for the use environment and current situation of most companies in this industry. At the same time, the service life is short, the friction loss during movement is large, and particulate matter will be generated. At the same time, the structure generates sound pollution, and the noise in the use environment of 12Rpm / Min can reach 45dB, and it needs to be replaced frequently, but the replacement process is relatively complicated, and additional manpower consumption and cost increase will be generated during the process.

[0003] The double-headed bridge-type tugboat load-bearing structure adopts a self-balancing design. Its structure consists of an inner ring, an outer ring, a rim, a bearing, a bearing core, a bridge bearing, and a double nylon support. The inner and outer rings are made of nylon, and the middle connecting part is made of steel. This existing structure has high requirements for the site and the use environment. If there is an inclined surface or a slight gap on the ground, it will cause a single head to be stressed, resulting in wear. At the same time, the two ends are unbalanced after wear, which reduces the service life and causes unstable use of the equipment. The load-bearing capacity is reduced, which hinders the operation of the equipment, reduces the overall use effect, and reduces the service life.

[0004] The slewing bearing has the advantage of simple structure. It consists of an inner ring, an outer ring, rolling elements and a sealing ring, all of which are made of steel and are designed as one-piece. However, this structure is not flexible in rotation, which is reflected in the high viscosity of the lubricant in the bearing raceway, seal damage, etc.; broken teeth, which are reflected in the case where the axes of the large and small gears are not parallel, resulting in broken teeth and causing the equipment to stop for replacement.

[0005] Based on the above situation, a composite wrapping packaging machine chassis load-bearing system is urgently needed. Summary of the invention

[0015] Furthermore, it also includes a threading system, which includes routing and fixing points, wherein the routing and fixing points are arranged based on electrical clearance and creepage distance.

[0016] In a second aspect, a working method of a chassis load-bearing system of a composite wrapping packaging machine includes: The driving gear is driven by the reduction motor to rotate, thereby reducing the speed of the driving gear.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Example 1 Reference Figure 1 , a composite wrapping packaging machine chassis load-bearing system of this embodiment includes: A main frame, a ring gear seat is arranged on the main base plate of the main frame, the ring gear seat is assembled on the main base plate of the main frame by fastening bolts, a driving gear is installed on the ring gear seat, a ring gear is meshed on the driving gear, and the driving gear is connected to a driving reduction motor.

[0027] Among them, Figure 1 As shown, the ring gear seat is assembled on the main bottom plate of the main frame by fastening bolts. The ring gear seat is an important fixed bracket for installing the ring gear, and its welding has strict requirements: Accuracy and precision: extremely high accuracy is required during the welding process to ensure the accuracy of the welding position; Weld formation: the weld formation should be beautiful and smoothly transition to the surface of the parent material. The height and width of the weld should meet specific standards and there should be no surface welding defects; Radiographic inspection: 100% of the tested ring seams are radiographically inspected, and the evaluation is based on JB4730 "Non-destructive Testing of Steel Pressure Vessels", and level III is qualified; Post-weld heat treatment: stress relief annealing is performed on products that pass the flaw detection, and the specific temperature and time are determined according to the material and product requirements; Joint mechanical property test: samples are taken from the heat-treated products, and the mechanical property tests of the welded joints, including tensile tests and bending tests, are performed to ensure the welding quality; Welding equipment: gear laser welding equipment is mainly composed of lasers, light guide systems, processing machine tools, and control systems. These equipment should be able to meet the specific requirements of gear welding; Welding process and quality control: the welding quality can be controlled by testing the surface and microscopic state of the weld, weld strength, gear torque, etc.

[0028] The driving reduction motor is assembled on the main base plate of the main frame by fastening bolts. The industry name of the reduction mechanism of the driving reduction motor is RV reducer, and its structure includes: Input shaft: The input shaft of the RV reducer is usually composed of a cylindrical gear and a bevel gear. The cylindrical gear transmits the high-speed rotating power to the reducer through the connection with the driving device. The bevel gear is connected to the output shaft to transmit the speed after deceleration; Output shaft: The output shaft of the RV reducer is usually connected to the bevel gear, and the speed is transmitted to the output device through the gear transmission system. The speed of the output shaft is usually low, but it has a large torque output; Reducer housing: The housing of the RV reducer is the main supporting part of its structure, which plays a role in fixing and protecting the internal gear transmission system. The housing is usually made of cast iron or steel, with sufficient strength and rigidity to withstand the load and vibration during the transmission process; Gear transmission system: The gear transmission system of the RV reducer is its core part, which is used to convert the high-speed rotation of the input shaft into the low-speed and high-torque rotation of the output shaft. It usually includes a pair of meshing gears, one of which is connected to the input shaft and the other is connected to the output shaft. The gear's module, number of teeth, tooth shape and other parameters will directly affect the transmission ratio and transmission efficiency of the reducer; Lubrication system: The lubrication system of the RV reducer is used to reduce friction and wear during gear transmission.

[0029] Working principle: First stage reduction device (planetary gear reducer): The rotation of the input shaft is transmitted from the input gear to the spur gear and reduced according to the gear ratio. This is the first reduction unit, in which the input gear is connected to the motor. Under the rotation of the motor, the input gear rotates synchronously, and the input gear and the motor have the same speed. Second stage reduction device (cycloidal pinwheel reducer): The spur gear is connected to the crankshaft and becomes the input of the second reduction unit. The RV gear is installed on the eccentric part of the crankshaft through a rolling bearing. In addition, the pin teeth on the inside of the housing, which are only one more than the number of RV gears, are arranged with the same pitch. If the fixed housing rotates the spur gear, the RV gear also moves eccentrically due to the eccentric movement of the crankshaft. At this time, if the crankshaft rotates one circle, the RV gear will rotate one tooth in the opposite direction of the crankshaft, and this rotation is output to the shaft of the second reduction unit.

[0030] Before installing the drive gear, it is necessary to confirm whether the motor and reducer are intact, and strictly check whether the sizes of the various parts connected to the drive motor and reducer match. Loosen the hexagon socket screw: unscrew the screw plug on the process hole on the side of the reducer flange, rotate the input end of the reducer to align the hexagon socket screw cap with the process hole, insert the hexagon socket tool to loosen the hexagon socket screw; align the drive motor shaft: hold the drive motor so that the keyway on the shaft is perpendicular to the reducer input end hole clamping screw, and insert the drive motor shaft into the RV reducer input end hole. When inserting, it is necessary to ensure that the concentricity of the two is consistent and the flanges on both sides are parallel; tighten the connection: to ensure that the flange connection of the two is evenly stressed, first screw the drive motor fastening screws arbitrarily, but do not tighten them; then gradually tighten the four fastening screws in the diagonal position; finally tighten the reducer input end hole clamping screw. Be sure to tighten the drive motor fastening screws first and then tighten the RV reducer input end hole clamping screws.

[0031] Connection and working method: First stage reduction device (planetary gear reducer): The input gear is connected to the motor. Under the rotation of the motor, the input gear rotates synchronously, and the speed of the input gear and the motor are consistent. The rotation of the input gear drives 2-3 planetary wheels to rotate at the same time. Since the number of teeth of the planetary wheels is large and the shape is large, the rotation speed of the planetary wheels is slower than that of the input gear, realizing the first stage reduction. Second stage reduction device (cycloidal pinwheel reducer): The front and rear ends of the crankshaft are respectively connected to the planetary wheels and the cycloidal wheels. After the planetary wheels rotate, the crankshaft rotates at the same speed. The crankshaft contains an eccentric part, and the eccentric part is embedded with a needle bearing and connected to the rolling bearing. Under the eccentric movement of the crankshaft, the cycloidal wheel moves with it under the action of the rolling bearing. When the cycloidal wheel contacts the pinwheel, it makes an eccentric movement (crank movement). As a result of the pinwheel being fixed, the cycloidal wheel rotates a gear distance in the opposite direction of the rotation direction of the crankshaft. Therefore, the rotation speed of the cycloidal wheel is slower than the eccentric part of the crankshaft, realizing the second stage reduction.

[0032] In the main frame structure, the material of the reinforced cable-stayed structure is Q235 reinforced rib square tube. The role of the reinforced rib square tube structure is mainly reflected in: Improving structural rigidity and strength: The reinforced rib square tube can increase the cross-sectional inertia moment of the structure, thereby enhancing the ability of the structure to resist deformation and improving the rigidity and strength of the structure. Dispersing stress: The reinforced rib square tube can disperse the concentrated load to a larger area, reduce the local stress level, reduce stress concentration, and thus improve the overall strength and stability of the structure. Optimizing material utilization: While maintaining the strength of the structure, by rationally designing the reinforced rib square tube, unnecessary material use can be reduced, costs can be reduced, and lightweight design can be achieved. Improving appearance: Reasonable reinforced rib square tube design can also enhance the overall aesthetics of the product. Adapting to different loads and environmental conditions: The reinforced rib square tube can adapt to the influence of temperature changes, sunlight temperature difference, support settlement, wind load, seismic force, etc. on the structure, and improve the adaptability and stability of the structure. Improving deformation resistance: Especially in composite square tubes, the use of reinforced ribs can improve its deformation resistance under internal and external pressure. Strengthening the local strength of the structure: In engineering structures, some parts are prone to deformation or damage due to complex forces and stress concentration. The ribbed square tube can effectively disperse these stresses and reduce stress concentration through its special shape and layout.

[0033] The role of reinforcing rib cross braces in the welding of the main frame is reflected in: enhancing structural strength and rigidity: reinforcing rib cross braces can enhance the strength and rigidity of the main frame, thereby saving materials, reducing weight and reducing costs; dispersing stress and reducing deformation: reinforcing rib cross braces can effectively disperse stress concentration through their shape and layout, and reduce the twisting deformation caused by uneven stress; transmitting concentrated force: in places where concentrated force acts, the reinforcing ribs play a force transmission role; improving the overall stability of the structure: reinforcing ribs help reduce structural deformation caused by factors such as uneven stress inside the main frame by increasing the local stiffness of the structure, thereby improving the overall stability.

[0034] The foot support structure includes: base plate: the base plate is the upper structure of the anchor structure, which is used to connect directly with the equipment. There are holes on the base plate, which are put on the bolts through the holes and are located above the adjusting bolts; Bolts: Bolts are the main components of the anchor structure used to connect the base plate and the base, and pass through the through holes from bottom to top; Adjusting bolts: The adjusting bolts are put on the bolts, and the axial center is a cavity, and the outer sleeve is connected with an adjusting nut to adjust the horizontal height of the foot; Adjusting nuts: The outer sleeve of the adjusting nut is connected to the adjusting bolt, and its outer diameter is larger than the inner diameter of the adjusting cavity. By rotating the adjusting nut, the adjusting bolt is driven to move up and down to adjust the relative distance between the base and the base plate; Base: The base is fixed on the foundation, with an adjusting cavity on the upper end and a There is a concave cavity, a through hole is provided between the adjustment cavity and the concave cavity, and the bolt passes through the through hole from bottom to top; Washer: The upper and lower ends of the base plate are respectively provided with first washers sleeved on the bolts, and a second washer is provided between the nut and the first washer. The first washer is usually a conical washer, and the second washer is a spherical washer, so as to ensure that when the bolt and the base plate are relatively tilted or the foundation is uneven, the anchor mechanism also has a higher fastening force; Fixed plate: The fixed plate is used to connect with the base plate and is fixed to the base plate by welding to increase the stability of the structure; Closing plate: The sealing plate is used to connect the base plate and the pad, and is fixed by welding to ensure that the connection between the base plate and the pad is more stable.

[0035] The expansion beam plays the same role as the reinforcing rib cross brace in the main frame structure, which is reflected in: enhancing structural strength and rigidity: the reinforcing rib cross brace can enhance the strength and rigidity of the main frame, thereby saving materials, reducing weight and reducing costs; dispersing stress and reducing deformation: the reinforcing rib cross brace can effectively disperse stress concentration through its shape and layout, and reduce the distortion caused by uneven stress; transmitting concentrated force: where there is concentrated force, the reinforcing rib plays a role in transmitting force; improving the overall stability of the structure: the reinforcing rib helps to reduce the structural deformation caused by factors such as uneven stress inside the main frame by increasing the local rigidity of the structure, thereby improving the overall stability Threading system: When arranging the threading system channel, you need to pay attention to: electrical clearance and creepage distance: including electrical clearance (spatial distance), creepage distance (surface distance) and insulation penetration distance, all of which need to meet certain safety distance requirements; wiring harness layout: the wiring harness should be routed along the position in the threading system to avoid the wiring harness being subjected to extrusion force or friction interference of moving parts. The wiring harness layout should have uniform and reasonable gaps with the pipeline and surrounding parts to ensure a neat appearance. Fixed point layout: Do not pull the wiring harness too tight during assembly. The reserved length of the wiring harness at the moving part should ensure that the wiring harness is not subjected to tension or extrusion when the component moves to the extreme position.

[0036] like Figure 2As shown, the components in the main frame are welded and formed, wherein all the mechanism components are assembled and connected based on the main frame 1; the ring gear seat 8 is assembled at the corresponding position of the chassis main frame by fastening bolts; the driving reduction motor 9 is assembled at the position of the chassis main frame by fastening bolts; the driving gear 10 is assembled on the power output shaft 11 of the driving reduction motor 9, and the two are fixed by bolts and matching keyways. The ring gear 12 is assembled on the ring gear seat 8 and is concentrically assembled and fixed by bolts, so that the driving output wheel 10 and the ring gear 12 are meshed with each other.

[0037] The conductive slip ring fixed shaft 13 is installed and fixed to the chassis frame in cooperation with the rotating conductive slip ring 14 and assembled concentrically. The follower connecting plate 16 is fixed to the mounting surface of the turntable 21 and rotates synchronously with the rotating conductive slip ring 14. The ring gear liner 15 is fixed on the ring gear 12, and a space is reserved to avoid the fixing bolts. The turntable origin sensing plate 17 is installed on the bottom mounting surface of the turntable 21. Cooperating with the origin detection sensor 18, it is used to detect the rotation positioning origin of the turntable to achieve the same initial position. The turntable tug 20 is fixed to the corresponding position of the main frame 1, and is evenly assembled in a circular shape, so that the turntable is balanced. The protective plate 19 is fixed on the chassis main frame 1 for safety protection.

[0038] Example 2 The difference between this embodiment and embodiment 1 is that this embodiment provides The driving reduction motor itself has a reduction mechanism, among which the first-stage reduction device is a planetary gear reducer: this device consists of an input gear and a planetary wheel. The input gear is connected to the motor. Under the rotation of the motor, the input gear rotates synchronously with it. The input gear and the motor have the same speed. The rotation of the input gear drives 2-3 planetary wheels to rotate at the same time. Since the planetary wheels have more teeth and larger shapes, the rotation speed of the planetary wheels is slower than that of the input gear, realizing the first-stage reduction. The first-stage reduction ratio is the ratio of the number of teeth of the planetary wheel to the number of teeth of the input gear, thereby achieving a reduction effect and reaching the required speed to drive the driving gear to rotate.

[0039] The working principle of the slewing bearing gear structure plus RV reducer can be divided into the following steps: Input stage: The rotational motion of the servo motor is first transmitted to the input gear, which is the first stage of the RV reducer, also known as the spur gear reduction mechanism. The rotation of the input shaft is transmitted from the input gear to the spur gear and is reduced according to the gear ratio.

[0040] Output stage: Ultimately, the rotation of the crankshaft is transferred to the output shaft through the interaction of the RV gear and the pinwheel, achieving the desired speed reduction and torque increase.

[0041] The motor speed is reduced by the reducer, which drives the driving gear to rotate, and the driving gear then drives the ring gear to rotate. Since the turntable is assembled on the ring gear, the turntable can rotate to achieve the required speed.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
