For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] The utility model provides a circular product coating mechanism, comprising a lifting mechanism 1, a fixed bottom plate 2, a film unwinding mechanism 3, a film cutting mechanism 4 and a film guiding mechanism 5 fixed on the fixed bottom plate 2, the lifting mechanism 1 is fixed on the equipment, the actuator of the lifting mechanism 1 is fixed to the fixed bottom plate 2, the film unwinding mechanism 3 comprises a passive unwinding roller 31, the passive unwinding roller 31 is rotatably connected to the fixed bottom plate 2, a film is wound on the outer surface of the passive unwinding roller 31, the film guiding mechanism 5 provides a guiding function for the film during transmission, the film cutting mechanism 4 can cut and separate the film part coated on the circular product 6 from the film on the unwinding roller, and the film guiding mechanism 5 is located between the film cutting mechanism 4 and the film unwinding mechanism 3.

[0025] The main function of the fixed bottom plate 2 is to integrate the film unwinding mechanism 3, the film cutting mechanism 4 and the film guiding mechanism 5 together, so as to facilitate one-step installation and control.

[0026] The lifting mechanism 1 can lift the laminating mechanism. In the embodiment of the utility model, the laminating mechanism is arranged above the product tooling. When laminating is required, the lifting mechanism 1 makes the laminating mechanism descend, approaches the circular product 6, and performs laminating on the circular product 6. When the laminating work is completed, the lifting mechanism 1 makes the laminating mechanism rise to avoid affecting the processing of the circular product 6.

[0027] The basic working principle of the utility model is as follows: a continuous film is wound around the passive unwinding roller 31, and the film is sequentially inserted into the film guide mechanism 5 and the film cutting mechanism 4. When the film coating mechanism approaches the circular product 6, the sticky side of the free end of the film on the passive unwinding roller 31 sticks to the circular product 6, and the circular product 6 rotates around its central axis through the equipment structure, driving the passive unwinding roller 31 to rotate, thereby releasing the film on the passive unwinding roller 31, and at the same time, the outer circumference of the circular product 6 can be covered with film all around. After the circular product 6 is covered with film all around, the film cutting mechanism 4 cuts and separates the film covering the circular product 6 from the film on the passive unwinding roller 31.

[0028] The utility model further comprises a pressing mechanism 7, which comprises a passive pressing roller 71, which is rotatably connected to the fixed bottom plate 2, and the pressing mechanism 7 is arranged beside the film guide mechanism 5, and is located on one side of the rotation direction of the round product 6. The pressing mechanism 7 can press the unrolled film tightly against the surface of the round product 6, so that the film adheres to the surface of the round product 6.

[0029] The film unwinding mechanism 3 also includes a through shaft 32 rotatably connected to the fixed bottom plate 2, and a front limiting mechanism 33 and a rear limiting mechanism 34 respectively fixed at the front and rear ends of the through shaft 32, and the front limiting mechanism 33 is detachably fixed on the through shaft 32, and the passive unwinding roller 31 is sleeved and fixed on the through shaft 32, and is located between the front limiting mechanism 33 and the rear limiting mechanism 34, and the interval value between the front limiting mechanism 33 and the rear limiting mechanism 34 is equal to the length value of the passive unwinding roller 31. The passive unwinding roller 31 is located between the front limiting mechanism 33 and the rear limiting mechanism 34, so that the unwinding roller is clamped between them by the limiting mechanism and the rear limiting mechanism 34, so that the passive unwinding roller 31 can rotate with the through shaft 32. The front limiting mechanism 33 can be disassembled, so that after the film on the passive unwinding roller 31 is used up, the unwinding roller can be removed, replaced with a new unwinding roller wrapped with a film, and continued to be put into use.

[0030] The film cutting mechanism 4 includes a cutter 41, a movable plate 42 and a cutting cylinder 43. The movable plate 42 is slidably connected to the fixed bottom plate 2. The film unwinding mechanism and the film guiding mechanism 5 are both fixed to the movable plate 42. The cutting cylinder 43 is fixed to the fixed bottom plate 2. The free end of the telescopic rod of the cutting cylinder 43 is fixed to the movable plate 42, so that the film unwinding mechanism 3 and the film guiding mechanism 5 can be raised and lowered relative to the film cutting mechanism 4. When it is necessary to cut the film, the telescopic rod of the cutting cylinder 43 is extended or shortened, so that the movable plate 42 is away from the fixed plate, so that the film is V-shaped, the valley point of the V-shaped is located at the blade of the cutter 41, and is tightly squeezed at the blade of the cutter 41, and when the movable plate 42 moves, the valley point of the V-shaped is cut.

[0031] The utility model also includes an emergency stop device 8, which can quickly stop the threading shaft 32 to prevent the passive unwinding roller 31 from being unable to stop in time due to the inertia of the threading shaft 32, thereby avoiding that after the circular product 6 is coated and the film is cut, the film on the passive unwinding roller 31 is still being released continuously, thereby affecting the coating of the next circular product 6.

[0032] The emergency stop device 8 in the utility model specifically includes a guide sleeve 81, an emergency stop block 82 and an emergency stop cylinder 83. The emergency stop cylinder 83 is fixed on the fixed base plate 2 and is located above the through-shaft 32. The free end of the telescopic rod of the emergency stop cylinder 83 fixes the emergency stop block 82. An arc groove 821 matching the through-shaft 32 is provided below the emergency stop block 82. The through-shaft 32 passes through the fixed base plate 2. The guide sleeve 81 is sleeved and fixed on the part of the through-shaft 32 located on the back of the fixed base plate 2. A channel 811 is provided above the guide sleeve 81. The cross-sectional shape and size of the channel 811 are consistent with the cross-sectional shape and size of the emergency stop block 82. When the film is cut, the telescopic rod of the emergency stop cylinder 83 quickly extends, extends the emergency stop block 82 into the channel 811, and presses the through-shaft 32 to stop the through-shaft 32 from continuing to rotate. The guide sleeve 81 plays a role in improving the guide for the descent of the emergency stop block 82.

[0033] The utility model also includes a blowing device 9, which is arranged on the side opposite to the rotation direction of the circular product 6. The blowing device 9 includes a vent pipe 91 and an air pump. The vent pipe 91 is fixed on the fixed bottom plate 2. The axial direction of the vent pipe 91 is consistent with the axial direction of the passive unwinding roller 31. The vent pipe 91 is provided with a plurality of air outlet holes 911 arranged at intervals. The air outlet of the air pump is connected to the air inlet of the vent pipe 91. The blowing device 9 can blow the free end of the film on the film guide mechanism 5 to the side of the rotation direction of the circular product 6 before lamination, and make the side covered with glue face the circumferential surface of the circular product 6, so as to avoid the side of the film covered with glue facing away from the circumferential surface of the circular product 6 during lamination, which may cause the film to separate from the circular product 6 after lamination.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
