Description

Technical Field

[0001] This utility model belongs to the field of transportation equipment and relates to a film roll transport vehicle. Background Technology

[0002] In the actual production process of polyester film, due to the wide production lines (up to 8780mm), the thickness and performance of the master roll edges are poor due to the bending effect of shaping and cooling. Therefore, edge trimming of the master roll is necessary, and the specific effective slitting width is determined according to the production line schedule. During the master roll slitting process, the trimmed edges are usually recycled and granulated for reuse, effectively saving raw material costs. At this point, the film roll transport vehicle becomes a key piece of equipment connecting the production line and the recycling pit. It is responsible for safely and efficiently transporting the cut waste film to the recycling pit for subsequent recycling processing.

[0003] To address this need, patent CN215752545U discloses a transport trolley specifically designed for plastic film rolls. This patent aims to provide a device capable of effectively carrying and transporting film rolls to meet the requirements for waste film recycling during plastic film production.

[0004] However, in practical applications, the size of the waste film rolls from recycling and granulation, i.e., the diameter, varies depending on the actual winding batch length. When transporting certain waste film rolls whose size exceeds its design range, the transport trolley may be unstable or fall off. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide a film roll transport vehicle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A film roll transport vehicle includes a frame and wheels, and also includes a support plate, a first support shaft, a first lifting mechanism and a second lifting mechanism located on the frame.

[0008] The first support shaft is parallel to the left and right direction. The support plate consists of a front plate and a rear plate, which are distributed on the front and rear sides of the first support shaft and are both hinged to the first support shaft.

[0009] The first lifting mechanism is located between the front panel and the frame, and the working end of the first lifting mechanism is in contact with the front panel.

[0010] The second lifting mechanism is located between the rear panel and the frame, and the working end of the second lifting mechanism is in contact with the rear panel.

[0011] When the first and second lifting mechanisms are not in operation, both the front and rear panels are in a horizontal position.

[0012] As a preferred technical solution:

[0013] In the film roll transport vehicle described above, both the first lifting mechanism and the second lifting mechanism are cylinders.

[0014] As described above, in a film roll transport vehicle, the piston rods of the first lifting mechanism and the second lifting mechanism are T-shaped, consisting of a horizontal part and a vertical part located below it. The horizontal part includes a second support shaft parallel to the left and right direction and two rollers sleeved on the left and right ends of the second support shaft and rotatably connected thereto.

[0015] As described above, the film roll transport vehicle has an L-shaped frame composed of a vertical plate and a horizontal plate, with the vertical plate located above and behind the horizontal plate. The upper end of the vertical plate extends backward in the front-rear direction to form a connector. The support plate, the first support shaft, the first lifting mechanism, and the second lifting mechanism are all located on the horizontal plate.

[0016] As described above, a film roll transport vehicle has two front wheels symmetrically distributed on the left and right sides. Each front wheel is mounted on a third support axle parallel to the left and right directions. The left and right ends of each third support axle are rotatably connected to the rear end of a first link. The front ends of all the first links are simultaneously rotatably connected to a fourth support axle parallel to the left and right directions. The front end of each first link is higher than the rear end. The fourth support axle is fixed to the bottom of a horizontal plate.

[0017] As described above, the film roll transport vehicle also includes two rear wheels symmetrically distributed on the left and right sides;

[0018] Both rear wheels are connected to a single rear wheel carrier simultaneously;

[0019] The rear wheel frame is I-shaped, including an upper plate, a middle connecting column, and a lower axle;

[0020] The lower axle is parallel to the left and right direction, and the two rear wheels are located on the left and right sides of the middle connecting column and are simultaneously rotatably connected to the lower axle.

[0021] The left and right ends of the upper plate are rotatably connected to the rear end of a second link. The front end of each second link is higher and the rear end is lower. The front ends of all the second links are simultaneously rotatably connected to a fifth support shaft parallel to the left and right direction. The fifth support shaft is fixed to the rear side of the middle of the vertical plate.

[0022] As described above, the film roll transport vehicle also includes a jack located at the rear of the vertical plate. The jack includes a handle, a base, a saddle, a safety release valve, an oil tank, and an oil pump. The handle can rotate in a vertical plane parallel to the front-to-back direction. The saddle is located below the connector and is fixedly connected to it. The base is located above the upper plate and is fixedly connected to it.

[0023] In the film roll transport vehicle described above, a safety release valve is located on the handle.

[0024] Beneficial effects:

[0025] (1) The film roll transport vehicle of this utility model is designed with adjustable front and rear plates (driven by the first and second lifting mechanisms and tilted around the first support shaft), which can closely fit waste film rolls of different diameters and has the function of clamping the film rolls to prevent them from falling off during transportation.

[0026] (2) The film roll transport vehicle of this utility model is designed with a liftable frame. When the edge material is unloaded, the frame of the transport vehicle is raised, allowing the edge material film roll to be directly unloaded from the slitting station onto the transport vehicle. This avoids the drawbacks of manual handling, saving labor and effort while improving safety. After the film roll is unloaded onto the transport vehicle, the frame is lowered slightly to complete the normal transport process. After the transport vehicle arrives at the pit, the frame is lowered further to complete the delivery of the edge material waste film to the pit, making it easier and safer for operators to complete the transport task without the need for manual handling.

The horizontal part 71 includes a second support shaft 711 parallel to the left and right direction and two rollers 712 sleeved on the left and right ends of the second support shaft 711 and rotatably connected thereto.

[0044] When the first lifting mechanism 6 and the second lifting mechanism 7 are not in operation, both the front plate 41 and the rear plate 42 are in a horizontal state.

[0045] The wheel consists of two front wheels 21 and two rear wheels 22; the two front wheels 21 and the two rear wheels 22 are symmetrically distributed from left to right;

[0046] like Figure 3 As shown, each front wheel 21 is mounted on a third support shaft 8 parallel to the left and right direction. The left and right ends of each third support shaft 8 are rotatably connected to the rear end of a first link 9.

[0049] When transporting film rolls using a film roll transport vehicle, firstly, the vehicle frame is moved to the vicinity of the slitting machine by the wheels, so that the support plate of the transport vehicle is facing the film roll to be cut. Then, the jack is used to operate the vehicle. By turning the handle, the oil pump is driven to raise the saddle, thereby raising the entire vehicle frame through the connecting parts. After that, the waste film rolls cut from the slitting machine fall directly onto the support plate of the transport vehicle. At this time, the first lifting mechanism and the second lifting mechanism are activated, so that the piston rods of the first lifting mechanism and the second lifting mechanism extend and push the front plate and the rear plate to tilt upward around the first support axis until the surfaces of the front plate and the rear plate are in contact with the waste film roll.

[0050] Subsequently, the transport vehicle is pushed to transport the waste film rolls to the pit location (before this, the safety release valve can be turned to release some of the pressure of the jacks, allowing the vehicle frame to fall back to a suitable position to improve the safety of the transport). After arriving at the pit, the safety release valve is turned to release the pressure of the jacks, allowing the vehicle frame to fall back. Then, the first and second lifting mechanisms are closed, allowing the front and rear panels to return to a horizontal state. The waste film rolls are then pushed into the pit for recycling, thus completing the transport process. Throughout the entire transport process, the wheels remain in contact with the ground.
