Description

Automatic film take-up device

Technical Field

The invention relates to the field of film production equipment, and in particular to an automatic film collecting device.

Background technique

During the film production process, the films are cut and collected on trays. When the trays are full, they are transported away by rollers and leave the film collection station. The empty trays are then transported to the station via rollers to collect the next tray of films. When the full trays are transported away and the next tray enters, the film collection work needs to be stopped and the film collection device needs to be shut down, thus reducing the efficiency of film collection.

In summary, the prior art lacks a film collecting device that can directly enter the next film collecting cycle without stopping after being filled.

Summary of the invention

The invention provides an automatic film collecting device, which can switch workstations back and forth to carry out film collecting work without stopping the machine, thereby saving disc changing time and improving film collecting efficiency.

In order to achieve the above object, the present invention adopts the following technical scheme:

The film automatic film collecting device comprises a feeding conveyor belt, a film cutting machine, a separating conveyor belt, an automatic film collecting machine and a conveyor belt. The feeding conveyor belt passes into the film cutting machine, and the film cutting machine is connected to the separating conveyor belt. The separating conveyor belt is connected to the automatic film collecting machine. The film enters the film cutting machine through the feeding conveyor belt, and the film cutting machine cuts the film and then enters the separating conveyor belt. The separating conveyor belt separates the distance between the films and conveys them to the automatic film collecting machine according to the set distance.

The automatic film collecting machine comprises two film collecting stations, one of which is in operation while the other is on standby, and the two film collecting stations work in a cycle interval.

A glue tray is provided on the film receiving station to collect the cut films. A conveyor belt is provided under the glue tray. When the glue tray is full, the full tray is transported away and an empty glue tray is moved in.

Furthermore, the automatic film collecting machine includes: a film collecting mesh belt, a first lifting platform, a second lifting platform, a lifting cylinder, a baffle, and a frame.

The first lifting platform and the second lifting platform are placed in parallel and arranged inside the frame. Conveyor belts are arranged above the first lifting platform and the second lifting platform for transporting the glue splicing tray.

The film collecting mesh belt is arranged on the periphery of the frame and can rotate freely, and the film collecting mesh belt passes above the first lifting platform and the second lifting platform. A drop hole is arranged on the film collecting mesh belt, and the area of the drop hole is larger than the area of the film. The film falls through the drop hole and falls into the glue receiving tray.

The lifting cylinder is installed on the frame. The lifting cylinder is arranged above the film collecting mesh belt in the vertical direction and above the connection position of the first lifting platform and the second lifting platform in the horizontal direction.

The extended end of the lifting cylinder faces the film collecting mesh belt. When the lifting cylinder is extended, a gap is left between the lifting cylinder and the film collecting mesh belt. The film collecting mesh belt can move freely, but the objects on the film collecting mesh belt are blocked by the lifting cylinder, and the film falls into the glue receiving tray on the first lifting platform.

When the lifting cylinder contracts, the lifting cylinder is lifted, and the objects on the sheet collecting mesh belt are not blocked by the lifting cylinder.

A baffle is also provided at the end of the frame, with a gap between the baffle and the frame. The sheet collecting mesh belt can move freely through the gap between the baffle and the frame, but objects on the sheet collecting mesh belt are blocked by the baffle.

Furthermore, the cutting machine is a continuous cross-cutting cutting machine.

Furthermore, the lifting cylinder is a baffle cylinder.

Furthermore, the initial positions of the first lifting platform and the second lifting platform are the raised positions, and each time a film is received, the first lifting platform and the second lifting platform are lowered by a certain distance. When the glue splicing tray is full, the first lifting platform and the second lifting platform are located at the end position, a glue splicing cycle is completed, and the glue splicing tray is moved away by the conveyor belt.

The working principle of the present invention is:

When one gluing station is working, the other gluing station is on standby. The first lifting platform is in the initial raised position, the lifting cylinder extends, and the film falls into the glue tray through the drop hole when passing the upper position of the first lifting platform. Every time a piece of film falls, the first lifting platform drops a certain distance. When the glue tray on the first lifting platform is full, the lifting cylinder contracts, and the film enters the upper position of the second lifting platform under the transportation of the film collection mesh belt, is blocked by the baffle, and falls into the glue tray on the second lifting platform. At this time, the second lifting platform is in the initial position and performs a cycle of gluing. When the second lifting platform is working, the glue tray on the first lifting platform is removed by the conveyor belt and an empty tray is moved in. The first lifting platform also rises to the initial position and waits for the next cycle of gluing. When the glue tray on the second lifting platform is full, the lifting cylinder extends, and the film falls into the glue tray on the first lifting platform under the obstruction of the lifting cylinder. The first lifting platform starts to work, and the second lifting platform returns to the initial position and waits for the next cycle of gluing.

The position of the blanking holes on the collecting mesh belt is calculated, and the position setting of the blanking holes can just adapt to the cycle of the gluing work and cooperate with the work.

The beneficial effects of the present invention are:

The present invention adopts two workstations for glue splicing. When one workstation is working, the other workstation is on standby. With the cooperation of the lifting cylinder and the film collection mesh belt, the film is controlled to fall into one of the workstations for glue splicing, and the glue splicing workstation that is not working performs the replacement of full and empty trays during this period, and returns to the initial position at the same time to prepare for the next working cycle. Therefore, the two workstations work continuously and alternately, eliminating the time of stopping for tray replacement and improving the film collection efficiency.

The embodiment of the present invention provides an automatic film collecting device, as shown in FIG. 1 and FIG. 2 , comprising a feeding conveyor belt 1 , a film cutting machine 2 , a separating conveyor belt 3 , an automatic film collecting machine, and a conveyor belt.

The feeding conveyor belt 1 is passed into the cutting machine 2, and the cutting machine 2 is connected to the separation conveyor belt 3;

The separation conveyor belt 3 is connected to the automatic film receiving machine, which includes two film receiving stations, one of which is in operation while the other is in standby mode, and the two film receiving stations work in a cycle interval. A glue receiving tray is arranged on the film receiving station, and a conveyor belt is arranged below the glue receiving tray.

The automatic film collecting machine comprises: a film collecting mesh belt 5, a first lifting platform 4, a second lifting platform 8, a lifting cylinder 6, a baffle 7, and a frame 10.

The first lifting platform 4 and the second lifting platform 8 are placed in parallel and arranged inside the frame 10 , and the conveyor belts are arranged above the first lifting platform 4 and the second lifting platform 8 .

The film collecting mesh belt 5 is arranged on the periphery of the frame 10 and can rotate freely. The film collecting mesh belt 5 passes over the first lifting platform 4 and the second lifting platform 8.

A blanking hole 9 is provided on the film receiving mesh belt 5, and the area of the blanking hole 9 is larger than the area of the film;

The lifting cylinder 6 is installed on the frame 10. The lifting cylinder 6 is arranged above the film collecting mesh belt 5 in the vertical direction and above the connection position of the first lifting platform 4 and the second lifting platform 8 in the horizontal direction.

The lifting cylinder 6 is a baffle cylinder, and the extended end faces the film collecting mesh belt 5. When the lifting cylinder 6 is extended, a gap is left between the lifting cylinder 6 and the film collecting mesh belt 5, and the film collecting mesh belt 5 can move freely, but the objects on the film collecting mesh belt 5 are blocked by the lifting cylinder 6. The film falls into the glue receiving tray on the first lifting platform 4. The first lifting platform 4 is working, and the second lifting platform 8 is on standby.

When the lifting cylinder 6 contracts, the lifting cylinder 6 is lifted, and the objects on the film collection mesh belt 5 are not blocked by the lifting cylinder 6. A baffle 7 is also provided at the end of the frame 10, and a gap is left between the baffle 7 and the frame 10. The film collection mesh belt 5 can move freely through the gap between the baffle 7 and the frame 10, but the objects on the film collection mesh belt 5 are blocked by the baffle 7, and the film falls into the glue receiving tray on the second lifting platform 4. The second lifting platform 8 is working, and the first lifting platform 4 is on standby.

The initial positions of the first lifting platform and the second lifting platform are the raised positions. Each time a film is received, the first lifting platform and the second lifting platform are lowered by a certain distance. When the glue splicing tray is full, the first lifting platform and the second lifting platform are located at the end position, a glue splicing cycle is completed, and the glue splicing tray is removed by the conveyor belt.

When one gluing station is working, the other gluing station is on standby. The first lifting platform 4 is located at the initial lifting position, the lifting cylinder 6 extends, and the film passes through the upper position of the first lifting platform 4 and falls into the glue-joining tray through the drop hole 9. Each time a piece of film falls, the first lifting platform 4 drops a certain distance. When the glue-joining tray on the first lifting platform 4 is full, as shown in Figure 1, the lifting cylinder 6 contracts, and the film enters the upper position of the second lifting platform 8 under the transportation of the film collection mesh belt 5, is blocked by the baffle 7, and falls into the glue-joining tray on the second lifting platform 8. At this time, the second lifting platform 8 is located at the initial position and performs a cycle of gluing work. When the second lifting platform 8 is working, the glue-joining tray on the first lifting platform 4 is removed by the conveyor belt, and an empty tray is moved in. The first lifting platform 4 also rises to the initial position, waiting for the next cycle of gluing work. When the glue splicing tray on the second lifting platform 8 is full, the lifting cylinder 6 extends, and the film falls into the glue splicing tray on the first lifting platform 4 under the obstruction of the lifting cylinder 6. The first lifting platform 4 starts working, and the second lifting platform 8 returns to the initial position to wait for the next cycle of glue splicing. The schematic diagram of one station working and the other station replacing the full tray is shown in Figure 3.

The positions of the blanking holes 9 on the sheet collecting mesh belt 5 are obtained through calculation, and the positions of the blanking holes 9 can be set to just adapt to the cycle of the glue splicing work and cooperate with the work.

The beneficial effects of the present invention are:

The present invention adopts two workstations for glue splicing. When one workstation is working, the other workstation is on standby. With the cooperation of the lifting cylinder and the film collection mesh belt, the film is controlled to fall into one of the workstations for glue splicing, and the glue splicing workstation that is not working performs the replacement of full and empty trays during this period, and returns to the initial position at the same time to prepare for the next working cycle. Therefore, the two workstations work continuously and alternately, eliminating the time of stopping for tray replacement and improving the film collection efficiency.
