Description

Technical Field

[0001] The utility model relates to a novel double-side driven intensive roller table which can be replaced in groups and belongs to the technical field of steel rolling equipment. Background Art

[0002] The dense rollers under the traditional spinning machine are generally composed of 1 set of motor reducers, 1 universal coupling, 1 roller bracket, 1 set of driving rollers and 35 sets of passive rollers. The motor reducer transmits the torque to the driving roller through the universal coupling under the action of electric energy. The driving roller transmits the torque to other rollers through the sprocket and chain drive to realize the rotation of the whole set of rollers. This type of roller adopts a narrow vertical bearing seat (generally UCPA209) as a support, and the roller sprockets are arranged on the same side; to ensure that the wire coil can fall into the roller after spinning, the roller gap is set to 5mm (the production specification is φ5.5-16mm), so the roller center distance is generally 130mm; this position is the first set of rollers of Stelmor air-cooled rollers, and the on-site ambient temperature is high when it is shut down for maintenance (the roller temperature of some steel grades is above 700℃ after stopping rolling, and the roller is red). Affected by the above-mentioned structural form and on-site production environment, there are the following problems:

[0003] 1. The narrow vertical bearing seat is fixed by bolts at the bottom, which may cause the bolts to loosen easily and make installation difficult. Frequent tightening is required, which increases manpower input. When the bolts are loose, the parallelism of the sprocket cannot be guaranteed, causing abnormal wear of the chain and shortening the online service life.

[0004] 2. The sprocket center distance is small (130mm), and the chain rotates many times per unit time, resulting in short chain online use time, easy tooth jumping and chain derailment.

[0005] 3. The rollers can only be replaced one by one, which takes a long time and has low replacement efficiency. There is a risk of heatstroke and burns when working in a high temperature environment.

[0006] 4. Single-sided transmission: When the chain breaks or falls off, the entire roller transmission will fail, and the wire coils spit out by the spinning machine will accumulate on the roller, posing the risk of flying steel and damaging the equipment. Utility Model Content

[0007] The utility model aims to provide a novel double-side driven dense roller table which can be replaced in groups, so as to solve the problems in the prior art.

[0008] The utility model is realized by adopting the following technical scheme: a novel double-sided driven group-replaceable dense roller, characterized in that: it comprises a plurality of roller units connected in sequence, the roller unit comprises a roller bracket fixed on a roller base, a plurality of conveying rollers are rotatably arranged on the roller bracket through a bearing seat, a sprocket is arranged at one end of the conveying roller, and the sprockets corresponding to the odd-numbered conveying rollers and the even-numbered conveying rollers on the entire dense roller are on the opposite sides; the adjacent sprockets on the same side cooperate with each other through chains; and it also comprises two groups of driving motors, which are respectively connected to one of the odd-numbered conveying rollers and the even-numbered conveying rollers through universal couplings.

[0009] Furthermore: a bearing seat mounting plate is arranged on the outer side of the roller support, and a bearing seat is bolted to the bearing seat mounting plate.

[0010] Furthermore: a bearing is arranged in the bearing seat, and the bearing is axially fixed by a limit platform and a retaining spring on the inner side of the bearing seat.

[0011] Furthermore: there are six groups of roller units, and each group of roller units has six conveying rollers.

[0012] The beneficial effects of the utility model are as follows: the structure of the utility model can be replaced and disassembled in a modular manner when replacing the roller table, thereby improving the replacement efficiency; the roller tables are arranged in a forward and reverse staggered manner to double the sprocket center distance, solve the problems of tooth jumping and chain derailment, and at the same time extend the online service life of the chain; through the arrangement of the bearing seat and the mounting plate, the impact resistance of the bearing seat is improved, the shaft hole is enlarged, and a single roller can be replaced after removing the bolts of the bearing seat mounting plate; in addition, when the chain on one side breaks or falls off, the other side can continue to rotate to transport the wire coil out of the dense roller table (the side where the chain breaks or falls off can continue to rotate under the action of inertia and friction), and at the same time the load on the motor can be reduced.

[0030] The driving roller group 4 includes a roller support 401, a driving roller 402, a passive roller 404, a bearing seat mounting plate 405, a bearing seat 405, a driving roller spacer 406, a spacer 407, a sprocket 408, and a roller end coupling 409.

[0031] The six rollers in the roller group are installed between the roller brackets 401, wherein a bearing seat 405, a driving roller spacer 406, and a roller end coupling 409 are installed on one side of the driving roller 402. The bearing seat 405 passes through the roller diameter of the driving roller 402 and is fixed to the roller bracket 401 with bolts. The driving roller spacer 406 is installed on the roller diameter of the driving roller 402 and connected to the outer side of the bearing seat 405. The roller end coupling 409 is installed on the roller diameter of the driving roller 402 and connected to the outer side of the driving roller spacer 406. The other side of the driving roller 402 is equipped with a bearing seat mounting plate 404, a bearing seat 405, a spacer 407, and a sprocket 408. The bearing seat mounting plate 404 passes through the roller diameter of the driving roller 402 and is fixed to the roller support 401 with bolts. The bearing seat 405 passes through the roller diameter of the driving roller 402 and is fixed to the bearing seat mounting plate 404 with bolts. The spacer 407 is installed on the roller diameter of the driving roller 402 and is connected to the outer side of the bearing seat 405. The sprocket 408 is installed on the roller diameter of the driving roller 402 and is connected to the outer side of the spacer 406. A bearing seat is installed on one side of the passive roller 403, and the bearing seat 405 passes through the roller diameter of the passive roller 403 and is fixed to the roller support 401 with bolts. A bearing seat mounting plate 404, a bearing seat 405, a spacer sleeve 407, and a sprocket 408 are installed on the other side of the passive roller 403. The bearing seat mounting plate 404 passes through the roller diameter of the passive roller 402 and is fixed to the roller support 401 with bolts. The bearing seat 405 passes through the roller diameter of the passive roller 402 and is fixed to the bearing seat mounting plate 404 with bolts. The spacer sleeve 407 is installed on the roller diameter of the passive roller 402 and is connected to the outer side of the bearing seat 405. The sprocket 408 is installed on the roller diameter of the driving roller 402 and is connected to the outer side of the spacer sleeve 406.

[0032] The passive roller group 5 includes a roller support 401, a passive roller 404, a bearing seat mounting plate 404, a bearing seat 405, a spacer 407, and a sprocket 408. The six rollers in the roller group are installed between the roller supports 401, and the roller installation method is the same as that of the passive roller in the driving roller group 4.

[0033] In summary, the new double-sided drive group-replaceable dense roller table is composed of 2 sets of drive motor reducers, 2 universal couplings, 1 roller table base, 1 set of drive roller group (2 drive rollers, 4 passive rollers), 5 sets of passive roller groups (6 passive rollers in each group, 30 in total), a total of 11 parts. Among them, 2 sets of drive motor reducers are arranged on both sides of this roller table; 6 sets of rollers are installed on the roller table base, among which 1 set of drive roller group is installed at the front end of the roller table base with bolts, and 5 sets of passive roller groups are fixed on the roller table base with bolts, installed after the drive roller group, until the end of the roller table base (evenly distributed), the sprockets of the roller group should be arranged at intervals during installation to ensure that the sprocket center distance is the same, the sprockets are connected by roller chains, and the drive motor reducer is connected to the drive roller group through a universal coupling. When the drive motor reducer is powered on and rotates, the drive motor reducer transmits the torque to the drive roller group through the universal coupling. The drive roller of the drive roller group then transmits the torque to the 17 passive rollers on the same side through the chain drive (roller chain and sprocket), thereby realizing the rotation of the entire roller table of the dense roller table.

[0034] The utility model has a double-sided drive function. When a chain breakage or chain-off failure occurs on one side, the other side (18 rollers) can operate normally. Under the action of inertia and friction, the wire coils can be smoothly transported out of the roller group to avoid the stacking of wire coils and damage to the wire laying machine equipment and flying steel; 36 single rollers are assembled into 6 groups of rollers, and the roller groups can be taken offline for maintenance. They can be replaced in groups during maintenance to avoid frequent lifting, greatly shortening the roller replacement operation time; the rollers are arranged in a positive and negative staggered manner to increase the sprocket center distance, solve the problem of tooth skipping and chain off, and at the same time extend the online service life of the chain; the roller bracket is grooved to increase the shaft The bearing seat mounting plate solves the problem of small inner hole of the outer spherical bearing with boss (UCFC209). After removing the bearing seat mounting plate, the roller can be pulled out horizontally from the roller bracket from the sprocket side. It has the function of replacing a single roller to avoid replacing a single roller in groups due to damage, which causes waste of spare parts. The outer spherical bearing with boss (UCFC209) is fixed with axial bolts, and the boss is used to bear the radial impact load of frequent starting and stopping, speed increase and speed decrease, which solves the problem of easy loosening of bolts and difficulty in bolt installation under impact load of narrow vertical bearing seat (UCPA209), and reduces the manpower input for frequent tightening.
