[0004] With regard to the above-mentioned related scheme, the winding operation of the composite plastic film is realized through the cooperation of motor three and winding roller one, and the material can be unloaded after the winding is completed. However, since the winding roller is connected to the output end of motor three by bolts and fastening nuts, when performing the unloading operation, it is necessary to use tools such as wrenches to remove the bolts and fastening nuts before the winding roller can be removed for unloading, which makes the unloading efficiency of the plastic film composite machine low. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a plastic film laminating machine capable of fast unloading, so as to solve the technical problems raised in the above-mentioned background technology.

[0010] Preferably, a driving motor is installed on the horizontal plate at the front end of one of the vertical plates, and the output end of the driving motor is connected to one of the rotating shafts through a coupling.

[0011] Preferably, a guide structure is provided at the top end of the base plate between the vertical plate and the heating composite structure, a tensioning mechanism is provided between the two guide structures, and the tensioning mechanism consists of a rotating motor, a screw, a threaded block, a pulley group, a support frame, a tensioning roller and a pressure sensor.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] When the existing plastic film compounding machine is performing the unloading operation, it is necessary to use a wrench or other tools to remove the bolts and the fastening nuts before the winding roller can be removed for unloading, which makes the unloading efficiency low. The utility model is provided with a mounting mechanism, because the connecting block and the connecting frame are clamped by the mounting plate and the mounting groove, and the movable plate and the connecting frame are elastically connected by the supporting spring, so that when the electric push rod works and retracts, the inclined push block slides in the inclined groove, and at the same time, the movable plate will drive the mounting plate to reset and separate from the mounting groove under the action of the supporting spring, and at this time, the connection block and the connecting frame can be separated by moving the winding roller upward, so that the winding roller can be quickly removed for fast unloading, so that the unloading efficiency of the plastic film compounding machine is improved;

[0015] In the existing plastic film laminating machine, the plastic film after thermal bonding is in use. Due to its high temperature, it is easy to stretch and deform during the process of being transmitted to the winding roller, which is not conducive to the subsequent winding operation. The utility model is provided with a tensioning mechanism. The composite plastic film passes through the guide structure and the tensioning roller and is wound up by the winding roller. The pressure size is detected in real time by the pressure sensor. When the pressure value is less than the set value, it means that the plastic film is loose. At this time, the output end of the rotating motor drives the screw rod to rotate under the action of the pulley group. Since the threaded block is threadedly connected to the screw rod, the threaded block and the tensioning roller are moved vertically downward to adjust the tension of the plastic film, thereby facilitating the subsequent winding operation.

[0027] See also Figure 1 , Figure 2 and Figure 7 It can be seen that the film is unwound by the unwinding structure 2, and the two layers of film are heated and composited by the heating composite structure 3. The composited plastic film passes through the guide structure 4 and the tensioning roller 906, and then is reeled in by the cooperation of the reeling roller 7 and the driving motor 6.

The outer periphery of the tensioning roller 906 is installed with a pressure sensor 907, and the outer surfaces of the two screw rods 902 are sleeved with a pulley group 904. A rotating motor 901 connected to one of the screw rods 902 through a coupling is installed at the top of one of the support frames 905;

[0029] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 It can be seen that the composite plastic film passes through the guide structure 4 and the tensioning roller 906 and is then wound up by the winding roller 7, and the pressure size is detected in real time by the pressure sensor 907. When the pressure value is less than the set value, it means that the plastic film is loose. At this time, the output end of the rotating motor 901 drives the screw rod 902 to rotate under the action of the pulley group 904. Since the threaded block 903 is threadedly connected to the screw rod 902, the threaded block 903 and the tensioning roller 906 move vertically downward to adjust the tension of the plastic film, thereby facilitating the subsequent winding operation.

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that both ends of the winding roller 7 are connected to a connecting block 11, and the ends of the two vertical plates 5 close to each other are connected to a connecting frame 10 through a rotating shaft.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that during the operation and extension of the electric push rod 807, the movable plate 803 is pushed by the inclined push block 806, so that the mounting plate 802 moves horizontally and is inserted into the mounting groove 801, thereby realizing the engagement and positioning between the connecting block 11 and the connecting frame 10 to realize the installation of the winding roller 7.

[0032] See also Figure 2 , Figure 3 and Figure 4 It can be seen that a support spring 804 is welded between the movable plate 803 and the connecting frame 10, and the movable plate 803 and the connecting frame 10 form an elastic structure through the support spring 804. When the electric push rod 807 works and retracts, the inclined push block 806 slides in the inclined groove 805. At the same time, the movable plate 803 will drive the mounting plate 802 to reset and separate from the mounting groove 801 under the action of the support spring 804. At this time, the connection block 11 and the connecting frame 10 can be separated by moving the winding roller 7 upward, so that the winding roller 7 can be quickly removed for fast unloading, thereby improving the unloading efficiency of the plastic film laminating machine.

The composited plastic film passes through the guide structure 4 and the tensioning roller 906, and then is reeled in by the cooperation of the winding roller 7 and the driving motor 6. After the reeling is completed, the electric push rod 807 is started, so that during the operation and contraction of the electric push rod 807, the oblique push block 806 slides in the oblique groove 805, and at the same time, the movable plate 803 drives the mounting plate 802 to reset and separate from the mounting groove 801 under the action of the supporting spring 804. At this time, the connection block 11 and the connection frame 10 can be separated by moving the winding roller 7 upward, thereby facilitating the rapid removal of the winding roller 7 for rapid unloading.
