Description

Technical Field

[0001] This utility model belongs to the field of film conveying technology, specifically relating to an automatic film delivery device. Background Technology

[0002] The existing automatic film delivery device only has a passive belt conveyor (with cylinder lifting). The film delivered to the position is flipped upwards in the direction shown in the diagram by the film detection device, so that the delivery device's conveyor belt and the passive roller of the upper conveyor belt form a certain clamping force on the film. The rotation of the passive conveyor belt is generated by the friction between the passive roller of the upper conveyor belt and the conveyor belt, which drives the delivery conveyor belt. Since the power is provided by friction, the speed of the delivery conveyor belt is unstable, and the clamping and delivery of the film by the delivery device is unstable, resulting in overall unstable operation and a low success rate. Moreover, since the length of the delivery conveyor belt varies greatly between the two working positions, an automatic tensioning spring is required to compensate for the length difference. When the compression of the springs on both sides changes, the conveyor belt of the automatic delivery device is prone to deviation, which affects the overall stability of the equipment operation. Therefore, an automatic film delivery device is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an automatic film feeder device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic film delivery device, comprising a film conveying assembly, an adjusting assembly, a delivery delivery assembly, two sets of tensioning assemblies, a transmission assembly, a drive assembly, and a delivery delivery conveyor belt. The adjusting assembly includes a cylinder and two double-ear ring supports. Both ends of the cylinder are connected to a support frame and the delivery delivery assembly respectively through the double-ear ring supports. The delivery delivery assembly includes a delivery frame. Both sides of the delivery frame are hinged to the support frame through pins. The double-ear ring supports are connected to one end of the delivery frame. The delivery frame is rotatably connected to a delivery belt passive roller, two rotating rollers, a tensioning roller, a delivery belt active roller, several side guard rollers, and a delivery tensioning roller.

[0005] The tensioning assembly includes two spring seats. The two lower spring seats are respectively connected to both sides of the conveyor frame, and the two upper spring seats are respectively connected to both sides of the support frame. A screw is connected inside the spring seat, and a clamping plate is slidably connected to the outside of the screw. A spring is sleeved on the screw, and both ends of the spring are connected to the spring seat and the clamping plate, respectively.

[0006] The transmission assembly includes a transmission chain, a driven sprocket, a tension sprocket, a steering sprocket, and a driving sprocket. The driving sprocket meshes with the driven sprocket, the tension sprocket, and the steering sprocket via the transmission chain.

[0007] The drive assembly includes a head conveyor belt drive roller, an upper conveyor belt driven roller, a head conveyor belt tension roller, and a head conveyor belt. The head conveyor belt drive roller transmits power through a driven sprocket. The head conveyor belt drive roller is connected to the upper conveyor belt driven roller, the head conveyor belt driven roller, two rotating rollers, a tension idler roller, and a head tension roller via the head conveyor belt.

[0008] By setting up the above structure, the problem of the conveyor belt easily running off-center due to the change in length between the two working positions is solved.

[0009] As a preferred embodiment, the film conveying assembly includes a lower conveying assembly, a support frame, and an upper conveying assembly. The upper conveying assembly consists of an upper conveyor belt drive roller, an upper conveyor belt drive roller, and a conveyor belt. Both the lower and upper conveying assemblies are connected within the support frame.

[0010] As a preferred embodiment, the passive sprocket is connected to the drive roller of the conveyor belt, the drive sprocket is connected to the passive roller of the upper conveyor belt, and the drive sprocket is connected to the support frame.

[0011] As a preferred embodiment, the steering sprocket is connected to the side of the support frame, and the tensioning sprocket is connected to the clamping plate located above.

[0012] As a preferred embodiment, the drive sprocket is configured as a single-row sprocket.

[0013] As a preferred embodiment, the tensioning roller is positioned between the two rotating rollers.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, after the feeder conveyor assembly can receive the film conveyed by the lower conveyor belt, the retracting cylinder drives the feeder conveyor assembly to rotate counterclockwise. This causes the feeder conveyor belt and the passive rollers of the feeder belt of the upper conveyor belt to form a certain clamping force on the film, thus conveying the film upward. Since both conveyor belts are powered, the feeder conveyor belt runs at a stable speed, and the feeder device clamps and conveys the film stably, resulting in stable overall film operation and a high success rate. During this process, because the conveying power comes from the second passive chain roller connected to the upper conveyor belt, accurate speed matching is ensured. The speed of the feeder conveyor belt is synchronized with that of the upper conveyor belt, and the length of the feeder conveyor belt remains basically unchanged between the two working positions. The conveyor belt of the automatic feeder device is not prone to deviation, thereby improving the overall stability of the equipment operation.

[0016] This invention features a steering sprocket. When the driving sprocket drives the steering sprocket, tension sprocket, and driven sprocket to rotate via the transmission chain, the driven sprocket rotates in the opposite direction to the driving sprocket under the action of the steering sprocket.
