Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machine equipment, in particular to a lifting device of a film blowing machine. Background Art

[0002] Film blowing machines are used to produce plastic wrap, garbage bags, and more. Initially, the plastic film produced by the film blowing machine needs to be guided. Typically, the film is passed upward over a two-way herringbone plate on the machine frame to flatten it, then turned over the first guide roller on the frame and finally guided downward to the equipment in the subsequent steps. This ensures that the film can be pulled out of the film blowing machine consistently and stably.

[0003] After searching, it was found that a Chinese patent document discloses a flat film blowing machine and a heating mechanism for the film blowing machine, publication number: CN205705231U. This film blowing machine does not have an auxiliary lifting mechanism, and the film head coming out of the die head needs to be manually lifted upward to the platform of the frame. During this operation, a person needs to hold the film head in one hand while climbing up the frame. This operation poses a great safety risk, and when the film blowing machine stops working, the plastic film will fall directly, which is easy to cause damage and is not conducive to production and processing. Therefore, it is necessary to propose a lifting device for the film blowing machine to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a lifting device for a film blowing machine, which has the effects of preventing the film from falling and ensuring safe and stable processing.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a lifting device of a film blowing machine, including a lifting frame, a lifting frame and a screw component for pushing the lifting frame to rise and fall are arranged on the lifting frame, a pressing part for fixing the end of the plastic film is arranged on the lifting frame, an anti-slip mechanism is arranged on the left side of the top of the lifting frame, the anti-slip mechanism includes a fixing frame installed on the side surface of the top of the lifting frame, a guide roller and an arc-shaped plate that fits the upper surface of the guide roller are arranged on the fixing frame, and two telescopic rods are arranged on the upper end of the arc-shaped plate.

[0006] By adopting the above technical solution, the end of the film is fixed to the lifting frame by a clamping part, and is lifted to the top by a screw component. When the film passes through the guide roller, the arc-shaped pressure plate is pushed by the telescopic rod to make it fit with the film. When the film blowing machine stops working, the end of the film is still hanging on the guide roller, avoiding its detachment and damage, and improving safety.

[0007] The utility model is further configured as follows: the telescopic rod includes a sleeve installed on the upper end of the inner wall of the fixed frame, the lower end of the sleeve is slidably provided with a movable rod connected to the arc plate, and an extrusion spring abutting the upper end of the movable rod is installed in the sleeve.

[0008] By adopting the above technical solution, the extrusion spring pushes the movable rod downward through expansion and contraction, pushing the arc plate downward, thereby stably placing the end of the film on the guide roller without affecting its transportation.

[0009] The utility model is further configured as follows: a movable groove is processed on the sleeve, and a movable block is installed on the upper end of the movable rod and slides up and down in the movable groove.

[0010] By adopting the above technical solution, during the lifting and sliding of the movable rod, the movable block at the end always slides on the movable groove, making the movement of the movable rod more stable and reliable.

[0011] The utility model is further configured as follows: the screw rod component includes a motor installed on one side of the top of the lifting frame, a screw rod is installed at the output end of the motor, a guide rod is installed on the other side of the lifting frame, and the external thread of the screw rod is installed with a movable plate slidably connected to the guide rod.

[0012] By adopting the above technical solution, the motor drives the screw to rotate, and under the guidance of the side guide rod, the movable plate is pushed up and down, thereby controlling the lifting frame to move upward and lifting the end of the film.

[0013] The utility model is further configured as follows: two electric push rods are installed on the movable plate, and an L-shaped frame connected to a pressing member is installed between the output ends of the two electric push rods.

[0014] By adopting the above technical solution, after the film is lifted to an appropriate height, the L-shaped frame is pushed to the left by the electric push rod, and the lifting frame drives the end of the film to bypass the guide roller, so that the film can be stably lifted and transported, reducing manual intervention and improving its safety.

[0015] The present invention is further configured as follows: upper and lower side walls of the lifting frame are both provided with openings for the movable plate to slide up and down, and a base is installed at the bottom of the lifting frame.

[0016] By adopting the above technical solution, the movable plate can be lifted and lowered smoothly and drive the lifting frame to lift the plastic film. The arrangement of the base makes the entire device more stable and reliable.

[0017] The present invention is further configured as follows: the pressing member includes two pressing plates arranged in the lifting frame, and a pushing member for pushing the bottom pressing plate is arranged at the bottom of the lifting frame.

[0018] By adopting the above technical solution, the end of the film is placed between the two pressing plates, and the distance between the two pressing plates is controlled by the pushing member, so that the end of the film is pressed and fixed on the lifting frame.

[0019] The present invention is further configured as follows: the pushing member includes a screw rod arranged on the bottom pressure plate, and two limiting rods slidably connected to the lifting frame are installed at the lower end of the pressure plate at the bottom.

[0020] By adopting the above technical solution, by rotating the screw, under the restriction of the limit rod, the bottom pressure plate can be pushed up, and the two pressure plates are close to each other, thereby pressing and fixing the end of the film.

[0021] The present invention is further configured as follows: a handle is installed at the lower end of the screw rod; the screw rod is rotatably connected to the pressing plate and is threadedly connected to the lifting frame.

[0022] By adopting the above technical solution, the handle can be held to conveniently rotate the screw to push the pressure plate upward.

[0023] The present invention is further configured as follows: anti-slip strips are installed on opposite sides of the two pressing plates, and a plurality of compression springs connected to the top wall of the lifting frame are installed on the upper pressing plate.

[0024] By adopting the above technical solution, the provision of the anti-slip strip enables a better pressing effect on the end of the plastic film, and the rebound effect of the compression spring further improves the pressing effect on the film.

[0025] The beneficial effects of the utility model are:

[0026] 1. The utility model places the end of the film between two pressure plates and rotates the screw to push the bottom pressure plate upward, so that the two pressure plates are close to each other, thereby pressing and fixing the end of the film. Then, the motor drives the screw to rotate, and under the guidance of the side guide rod, the movable plate is pushed up and down, thereby controlling the lifting frame to move upward, so that the end of the film is lifted, and no manual lifting operation is required, making the processing safer and more convenient.

[0027] 2. In this utility model, when the plastic film passes through the guide roller, the extrusion spring pushes the movable rod downward through expansion and contraction, pushing the arc plate downward, thereby stably placing the end of the film on the guide roller without affecting its transportation. When the film blowing machine stops working, the end of the film is still hanging on the guide roller to avoid it from detaching and causing damage. BRIEF DESCRIPTION OF THE DRAWINGS
