[0002] With the development of high-end mechanical equipment manufacturing industry, the mechanical equipment industry used in the packaging field has also developed rapidly. The film-releasing synchronous belt assembly device is an indispensable part of the packaging machine. When the machine is packaging, it controls the film-releasing speed and completes synchronous film-releasing to avoid problems such as excessive rotation or stretching deformation of the film roll due to its own inertia.

[0003] A synchronous film releasing device, such as a traction mechanism of a single-pull film packaging machine disclosed in Chinese patent application CN201816782U, includes a synchronous wheel bracket, a pair of synchronous wheels, a cylinder, a synchronous belt, a slide plate and a rear support. A pair of synchronous wheels are installed on the synchronous wheel bracket, the two synchronous wheels are placed vertically, a motor is installed on the synchronous wheel at the lower end, a synchronous belt is wrapped on the synchronous wheel, the synchronous wheel bracket is fixed on the slide plate seat, one side of the slide plate seat is connected to the cylinder, and one end of the cylinder is fixed to the rear bracket.

[0004] Although the device has many beneficial effects, it still has some shortcomings that need to be improved. During long-term use of the existing device, the film unwinding synchronous belt and the bearing will be offset and misaligned, and frequent adjustment is required. When the motor stops the film, there is no brake mechanism, and the film roll will rotate excessively or stretch and deform due to its own inertia. When installing the film roll, the film unwinding synchronous belt device must be manually lifted, which makes installation inconvenient and even requires multiple people to operate. In view of this, we propose a film unwinding synchronous belt assembly device. Utility Model Content

[0025] refer to Figure 1 and Figure 3 , one end of the motor plate shaft 1 is fixed by a film placing motor locking sleeve 5, and the other end of the motor plate shaft 1 is fixedly connected with a locking spacer 6, which is engaged with the film placing motor locking sleeve 2 8, and the locking spacer 6 is engaged with the film placing motor locking sleeve 2 8 to lock the position of the motor plate shaft 1, and the motor plate shaft 1 is fixed on the film placing bracket, and the locking spacer 6 is not engaged with the film placing motor locking sleeve 2 8 when the motor plate shaft 1 position is not locked, and the motor plate shaft 1 can rotate outside the film placing bracket, and the film placing motor The other end of the machine locking sleeve 8 is fixedly connected to the motor base plate 2, and a pin hole is opened on the other side of the motor base plate 2. A knob plunger 7 is pinned on the inner side of the pin hole, and a packaging machine bracket 23 passes through the outer side of the knob plunger 7. The staff pulls the knob plunger 7, and the knob plunger 7 moves inside the packaging machine bracket 23 until the knob plunger 7 is no longer engaged with the motor base plate 2. When the other end of the packaging machine bracket 23 is raised, the motor plate shaft 1 is rotated by force, and the motor plate shaft 1 is fixed on the film placing bracket at a certain angle.

[0026] refer to Figure 1 and Figure 2The motor plate shaft 1 is axially connected to the packaging machine bracket 23, a reduction motor 9 is arranged on one side of the top of the packaging machine bracket 23, and a film placing auxiliary wheel assembly box 19 is arranged on the other side of the packaging machine bracket 23. The output end of the reduction motor 9 is movably connected to the film placing auxiliary wheel assembly box 19, and the film placing auxiliary wheel assembly box 19 includes a film placing motor shaft 12, and the film placing motor shaft 12 is electrically connected to the output end of the reduction motor 9. A film placing active synchronous gear 11 is arranged on the outside of the film placing motor shaft 12, and a film placing synchronous belt 10 is sleeved on the outside of the film placing active synchronous gear 11. The other end of the film placing synchronous belt 10 is sleeved on the outside of the film placing driven synchronous gear 15. When the reduction motor 9 rotates, the film placing synchronous belt 10 is limited to the use surface of the film placing active synchronous gear 11 and the film placing driven synchronous gear 15, which can limit the position of the film placing synchronous belt 10 , effectively avoiding the deviation and misalignment of the film unwinding synchronous belt 10, a film unwinding driven wheel shaft 17 is fixedly arranged in the middle of the film unwinding driven synchronous gear 15, and a nut flat spring washer combination 18 is fixedly arranged on the top of the film unwinding driven wheel shaft 17, and the nut flat spring washer combination 18 passes through the packaging machine bracket 23, and the film unwinding motor shaft 12 and the other end of the film unwinding driven wheel shaft 17 are both provided with dust covers 21, and both sides of the film unwinding active synchronous gear 11 and the film unwinding driven synchronous gear 15 are provided with pressure cover boxes 16, and the tooth surfaces of the film unwinding active synchronous gear 11 and the film unwinding driven synchronous gear 15 are lower than the two sides of the film unwinding auxiliary wheel assembly box 19, and the top of the film unwinding driven wheel shaft 17 is movably connected with the deep groove ball bearing 3 through the nut flat spring washer combination 18, and the deep groove ball bearing 3 is arranged at one end of the packaging machine bracket 23, and a film unwinding motor pressure cover 13 is arranged on the top of the reduction motor 9.

[0027] When the device starts the film unwinding operation, when the reduction motor 9 rotates, since the tooth surfaces of the active synchronous gear 11 and the driven synchronous gear 15 of the film unwinding are lower than the two sides, the film unwinding synchronous belt 10 is limited to the use surface of the active synchronous gear 11 and the driven synchronous gear 15 of the film unwinding, the contact area between the film unwinding synchronous belt 10 and the film roll is increased, and the friction force is increased, so as to achieve the purpose of limiting the running position of the film unwinding synchronous belt 10.

At this time, the film placing motor locking sleeve 28 and the locking spacer sleeve 6 are no longer locked and fixed. Then, one end of the packaging machine bracket 23 is raised, and the packaging machine bracket 23 can drive the reduction motor 9 fixed on one side and the film placing auxiliary wheel assembly box 19 to rotate synchronously. The packaging machine bracket 23 drives the motor plate rotating shaft 1 to rotate on the film placing bracket. After rotating to the appropriate position, the knob plunger 7 is pushed in the opposite direction, so that the knob plunger 7 fixes the motor base plate 2. At this time, the film placing device as a whole is fixed at a certain angle to the packaging machine bracket 23, and the film placing auxiliary wheel assembly box 19 can be fixed at a certain angle by the knob plunger 7, so that when replacing the packaging film, the film placing auxiliary wheel assembly box 19 can be limited in position without continuous lifting by manpower, making the installation of the packaging film more labor-saving and efficient, reducing the difficulty of installing the film roll, facilitating operation, and improving efficiency.
