Technical Field
[0001] This utility model relates to the field of feeding equipment technology, specifically a feeding device for the production of multi-specification plastic sheets. Background Technology
[0002] With the increasing domestic demand, the applications of thermoformed plastic sheets for packaging are becoming more and more widespread, and the usage is increasing year by year. "Sheets with high barrier properties" have become the target of competition among various manufacturers. After injection molding or extrusion, plastic sheets are formed into continuous sheets, and they are generally wound up using winding equipment during the unloading process.
[0003] Chinese Patent Publication No. CN222539997U discloses a "Feeding Equipment for Multi-Specification Plastic Sheet Production," comprising a frame, a support frame, and a locking device. A motor is mounted on the frame, driving a take-up roller. The support frame is rotatably mounted on the frame, and a set of support rollers is rotatably mounted on the support frame. The locking device includes a locking part and a locking mating part, one disposed on the frame and the other correspondingly disposed on the support frame. The locking part and the locking mating part can cooperate with each other. When the locking part and the locking mating part are engaged, the set of support rollers supports the take-up roller from bottom to top. This application allows the support rollers to support the take-up roller from bottom to top through rotation, and then the locking device fixes the support frame. Because the take-up roller is supported by the support rollers, the load on the motor output shaft is reduced, thus increasing its service life.
[0004] While existing technology can support the take-up roller, it is difficult to replace the take-up roller during use, making quick replacement impossible. Furthermore, defects such as wrinkles and bubbles occur during the winding process, affecting the winding quality. Additionally, the winding speed cannot be adjusted according to production needs. Different plastic sheets may have different thicknesses, materials, and widths, requiring different winding speeds to ensure winding quality. This technology cannot adapt to these changes, resulting in unstable winding quality. Utility Model Content

At the same time, the winding speed cannot be adjusted during use, and it is impossible to adjust it according to production needs. Different plastic sheets may have different thicknesses, materials and widths, requiring different winding speeds to ensure winding quality. The inability to adapt to these changes leads to unstable winding quality.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a feeding device for the production of multi-specification plastic sheets, including a back plate, a connecting component on one side of the back plate, and a speed changing component on one side of the back plate;
[0007] The connecting assembly includes a base plate, which is fixedly connected to one side of the outer surface of the back plate. A rotating shaft is rotatably embedded inside the back plate, and a take-up roller is slidably sleeved on the outer surface of the rotating shaft. Multiple limiting plates are fixedly connected to the outer surface of the rotating shaft. Multiple connecting grooves are provided inside the take-up roller, and the multiple limiting plates are slidably embedded inside the connecting grooves.
[0008] The transmission assembly includes a support block, and a transmission column is rotatably embedded inside the support block. A conical wheel is fixedly connected to the outer surface of the transmission column. A small threaded rod is rotatably embedded inside the support block, and a small threaded block is threadedly fitted onto the outer surface of the small threaded rod. A roller is rotatably embedded inside the small threaded block.
[0009] Preferably, a power rod is rotatably embedded inside the support block, the roller is slidably sleeved on the outer surface of the power rod, and one side of the outer surface of the transmission column is fixedly connected to the rotating shaft.
[0010] Preferably, a large threaded rod is rotatably embedded inside the base plate, and a large threaded block is threadedly fitted on the outer surface of the large threaded rod. An electric actuator is fixedly connected to the top of the outer surface of the large threaded block, and a limit block is fixedly connected to the top of the outer surface of the electric actuator. The limit block is slidably fitted on the outer surface of the rotating shaft. Multiple limit rods are fixedly connected to one side of the outer surface of the base plate, and the large threaded block is slidably fitted on the outer surface of the limit rods.
[0011] Preferably, a plurality of connecting blocks are fixedly connected to the top of the outer surface of the base plate, and a lower connecting rod is rotatably embedded inside each of the plurality of connecting blocks. A plurality of connecting plates are fixedly connected to the outer surface of the lower connecting rod, and an upper connecting rod is rotatably embedded inside each of the plurality of connecting plates. A fitting wheel is rotatably sleeved on the outer surface of the upper connecting rod.
[0012] Preferably, a fixing block is fixedly connected to one side of the outer surface of the back plate, a motor box is fixedly connected to one side of the outer surface of the support block, and a moving motor is installed inside the motor box. The output shaft of the moving motor is fixedly connected to a small threaded rod. A power motor is installed inside the motor box, and the output shaft of the power motor is fixedly connected to a power rod.
[0013] Preferably, a motor block is fixedly connected to one side of the outer surface of the back plate, and a threaded motor is provided on the top of the outer surface of the motor block, and the output shaft of the threaded motor is fixedly connected to a large threaded rod.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] Firstly, this utility model involves placing a take-up roller on the outer surface of a rotating shaft, inserting a limiting plate fixedly connected to the rotating shaft into the connecting groove inside the take-up roller, and then activating a threaded motor on top of the motor block. The output shaft of the threaded motor is fixedly connected to a large threaded rod, which drives the large threaded rod to rotate. The rotation of the large threaded rod causes the large threaded block to move. After the limiting block is placed on the outer surface of the rotating shaft by an electric push rod on top of the large threaded block, the threaded motor drives the limiting block to restrict the other side of the take-up roller. When the take-up roller is winding, the bonding wheel keeps pressing on the take-up roller, thereby compacting the wound plastic sheet. Through the above technical solution, the efficiency of changing the take-up roller is improved, and the plastic sheet is kept flat and tight during the winding process.
[0016] Secondly, when the winding speed needs to be adjusted, the power motor inside the motor housing is turned on. The output shaft of the power motor is fixedly connected to the power rod, which drives the power rod to rotate. The protrusions on the surface of the power rod drive the roller to rotate, and the roller contacts the surface of the conical wheel. The roller is made of a non-slip, wear-resistant material with moderate hardness. The roller transmits power to the conical wheel, which is connected to the rotating shaft through a transmission column. The conical wheel drives the rotating shaft to rotate. When the speed needs to be adjusted, the movable motor inside the motor housing is turned on. The output shaft of the movable motor is fixedly connected to the small threaded rod, which drives the small threaded rod to rotate. The rotation of the small threaded rod drives the small threaded block to move, which in turn drives the roller to move. Due to the change in the radius of the conical wheel, the roller experiences a speed change during rolling. The movement of the roller changes the contact position with the conical wheel, thereby achieving speed change. Through the above technical solution, different production needs can be met, and the winding speed can be adjusted according to production needs, thus adapting to winding tasks of different materials and specifications.

Then, by turning on the threaded motor 9 at the top of the motor block 101, the output shaft of the threaded motor 9 is fixedly connected to the large threaded rod 3. The threaded motor 9 drives the large threaded rod 3 to rotate, and the rotation of the large threaded rod 3 drives the large threaded block 301 to move. After the limiting block 304 is sleeved on the outer surface of the rotating shaft 4 by the electric push rod 303 at the top of the large threaded block 301, the threaded motor 9 drives the limiting block 304 to restrict the other side of the take-up roller 402. When the take-up roller 402 is winding, the bonding wheel 5 is always pressing on the take-up roller 402, thereby compacting the wound plastic sheet. Through the above technical solution, the efficiency of changing the take-up roller is improved, and the plastic sheet is kept flat and tight during the winding process.

The roller 702 transmits power to the conical wheel 6. The conical wheel 6 is connected to the rotating shaft 4 through the transmission column 601 and rotates. The conical wheel 6 drives the rotating shaft 4 to rotate. When adjustment is needed... When the rotation speed is reached, the movable motor 801 inside the motor housing 8 is turned on. The output shaft of the movable motor 801 is fixedly connected to the small threaded rod 7. The movable motor 801 drives the small threaded rod 7 to rotate. The rotation of the small threaded rod 7 drives the small threaded block 701 to move. The movement of the small threaded block 701 drives the roller 702 to move. Due to the change in the radius of the conical wheel 6, the roller 702 will experience a change in speed during the rolling process.

The limiting plate 401, which is fixedly connected to the rotating shaft 4, is inserted into the connecting groove 403 inside the take-up roller 402. Then, the threaded motor 9 at the top of the motor block 101 is activated. The output shaft of the threaded motor 9 is fixedly connected to the large threaded rod 3.
