As an embodiment, as shown in fig. 2 and 3, in the reel changer with the above structure, a bottom frame 13 is disposed at the bottom of the uncoiler 2, and the bottom frame 13 is provided with a plurality of sets of pulley assemblies and is slidably connected with the ground rail 1 through the plurality of sets of pulley assemblies. The pulley components comprise a first rotating shaft 14 and pulleys 15 arranged at two ends of the first rotating shaft 14, wherein a gear 16 is sleeved on the first rotating shaft 14 of one group of the pulley components and is in transmission connection with a third speed reducing motor 18 arranged below the chassis 13 through a chain 17, and the chassis 13 reciprocates along the ground rail 1 under the driving of the third speed reducing motor 18, so that the uncoiler 2 and the conveying table 3 reciprocate along the ground rail 1, and the switching of the position of the uncoiler 2 is realized.

In the reel changer having the above-described structure, although the sliding of the chassis 13 can be controlled by the third reduction motor 18, due to the inertia, the chassis 13 slides along the slide rail even if the third reduction motor 18 stops operating. In order to prevent the chassis 13 from sliding out of the ground rail 1, as shown in fig. 1, two ends of the ground rail 1 are provided with stop blocks 22, and the chassis 13 can be stopped from sliding by the stop blocks 22.

Further, as shown in fig. 1, a buffer member 23 is arranged on the stop block, and the buffer member 23 can reduce the impact of the bottom frame 13 on the stop block 22, so that the service life of the device is prolonged. Furthermore, the two ends of the track of the ground rail 1 are also provided with buffer parts 23, and the buffer parts 23 can be abutted to the pulleys 15 sliding to the end parts, so that a better buffer effect is achieved on the stop of the base.

The coil changing machine with the structure comprises a conveying table 3, wherein the conveying table 3 can only reciprocate along a ground rail 1 together with an uncoiler 2, however, a certain distance exists between the ground rails 1 of adjacent stations or between the ground rails 1 of the adjacent stations and the uncoiler 2, so that the conveying table 3 can move along a conveying belt 7 when the uncoiler 2 uncoils the sheet of the adjacent stations in a butt joint mode, especially when the sheet is initially received, because the bending degree of a steel coil or a metal sheet is not enough, the condition that the coil is not in butt joint due to gaps or too large distance is easy to occur, manual assistance is needed, the sheet is lapped on the conveying belt 7, the uncoiled sheet can move along the conveying belt 7, the labor cost is increased, and workers are easily injured due to rebounding of the sheet.

In order to solve the above technical problem, the conveyor belt 7 is configured to smoothly receive the sheet material unwound by the next station uncoiler 2, in some embodiments, as shown in fig. 4, the conveying table 3 further includes a rack 24, a conveying frame 25 mounted on the rack 24, and a fourth driving mechanism configured to drive the conveying frame 25 to reciprocate along the rack 24 toward the next station uncoiler 2.

Specifically, as shown in fig. 4, the fourth driving mechanism includes two parallel second rotating shafts 27 erected on the gantry 24, a driving belt 28 sleeved on the second rotating shafts 27, and a fourth speed-reducing motor 29 in transmission connection with one of the second rotating shafts 27, and the fourth speed-reducing motor 29 is electrically connected to the controller. The conveying frame is connected with a driving belt 28 through a connecting piece 26, when the driving belt 28 is driven by a fourth speed reducing motor 29 to rotate, the conveying frame moves along with the driving belt 28, and then the conveying belt 7 moves towards the direction of the uncoiler 2 at the next station, so that the conveying belt 7 extends into the lower part of the reel 5 of the uncoiler 2 at the next station, and the uncoiled sheet is convenient to receive. Moreover, because the fourth speed reducing motor 29 is electrically connected with the controller, the fourth speed reducing motor 29 can be better started and closed under the control of the controller, so that the conveying belt 7 can smoothly receive the sheets.

During operation, the uncoiler 2 of the previous station is uncoiled, the third speed reduction motor 18 is started, the uncoiler 2 is moved to the tail end of the ground rail 1, and at the moment, the conveyer belt 7 of the previous station is over against the feeding hole and the reel 5 of the uncoiler 2 of the next station. The fourth gear motor 29 starts, and will carry frame 25 to remove towards next station decoiler 2, makes conveyer belt 7 stretch into the spool 5 below of next station decoiler 2, and simultaneously, next station decoiler 2 starts the operation, unreels, and the sheet of unreeling just falls into on the conveyer belt 7 of previous station to under the effect of conveyer belt 7, carry to material loading mouth department, carry out the feed for production line. After the front station conveying belt 7 smoothly receives the sheet unreeled at the next station, the fourth speed reduction motor 29 reversely rotates to enable the conveying belt 7 to return to the initial state, and the sheet at the next station is continuously fed to the feeding opening under the traction action of the conveying belt 7.

Through the rack 24, the conveying frame 25 and the fourth driving mechanism, the conveying belt 7 can move towards the uncoiler 2 at the next station, the distance between the conveying belt 7 at the previous station and the reel 5 at the next station can be shortened, the conveying belt 7 at the previous station smoothly supports the sheet uncoiled at the next station, and continuous feeding is guaranteed.

In order to better control the moving distance of the conveying frame 25, as shown in fig. 4, a plurality of second position sensors 30 are arranged on the side frame of the rack 24, the position sensors are identical to the first position sensors 19 arranged on the ground rail 1 in structure and principle, and each of the position sensors comprises an induction sheet and a proximity switch, and the proximity switches are electrically connected with the controller and used for acquiring the position information of the conveying frame 25, so that the controller can better control the fourth speed reducing motor 29. Specifically, the second position sensors 30 include a front position sensor, a zero position sensor and a rear position sensor, and the position of the conveying frame 25 can be obtained through the front position sensor, the zero position sensor and the rear position sensor, so that the controller can control the operation of the fourth speed reduction motor conveniently.

The roll changing machine with the structure can only transmit sheets with fixed thickness due to the fact that the distance between the compression roller 8 and the conveying belt 7 is fixed, and therefore adaptability of the equipment is poor. In order to solve the technical problem, as an improved technical solution, as shown in fig. 4, two sides of the conveying frame 25 are provided with fifth driving mechanisms 31 opposite to each other, an output end of the fifth driving mechanism 31 is provided with a rotating ball connecting member 32, the rotating ball connecting member 32 is movably connected with two ends of the pressing roller 8, and the fourth driving mechanism is electrically connected with the controller. The fifth driving mechanism may be a pneumatic cylinder or a hydraulic cylinder. Through the fifth driving mechanism who sets up, can make compression roller 8 reciprocate, the distance of adjustment compression roller 8 and conveyer belt 7 satisfies the sheet of different thickness and carries, improve equipment's adaptability. In the specific implementation process, the height of the compression roller 8 can be adjusted according to the thickness of the sheet, the lifting height of the output shaft of the fifth driving mechanism is controlled through the controller, and the height of the compression roller 8 is adjusted very conveniently.

In the above-structured conveyance table 3, the frictional force between the sheet and the conveyor belt 7 is increased by adjusting the height of the upper roller in the conveyance of the coil, but when the conveyor belt 7 is loosened, the frictional force is reduced. Therefore, in some embodiments, as shown in fig. 4, in the reel changer of the above-mentioned structure, the conveying table 3 further includes a lower roller 9, the lower roller 9 is mounted on the conveying frame and is wrapped in the conveying belt 7, and the lower roller 9 abuts against the conveying belt 7 at the top thereof and is positioned corresponding to the upper roller, and has the function of supporting the conveying belt 7 upward. When the sheet passes between the upper roller and the lower roller 9 under the action of the conveyer belt 7, the friction force between the sheet and the conveyer belt 7 can be increased through the combined action of the upper roller and the lower roller 9, and the sheet is further better pulled and conveyed.

In the reel changer having the above-described configuration, when the conveyor belt 7 conveys a sheet, the press roller 8 can restrict and pull the sheet only in the vertical direction, but cannot restrict the sheet in the horizontal direction, so that the sheet tends to be deviated during conveyance. In order to solve the technical problem, as shown in fig. 4, a plurality of edge guide rollers 33 are disposed on two sides of the conveying frame 25, and the edge guide rollers 33 can limit the position of the sheet, so as to prevent the sheet from deviating from the conveying direction of the conveying belt 7 during the moving process, and further to make the conveying of the sheet by the conveying belt 7 smoother.
