Description

Technical Field

[0001] The utility model relates to the technical field of plastic film production and processing equipment, in particular to a quantitative feeder for conveying plastic film raw materials. Background Art

[0002] Plastic film refers to a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, which is used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] There are many equipments needed in the production process of plastic film, such as blow molding machines, printing machines, glue making machines, computer heat sealing and cold cutting machines, etc. Before blowing the plastic film, the plastic particles need to be put into the production equipment for melting, and then the film is blown after melting.

[0004] Existing plastic film raw material feeders generally feed materials through screw feeders, and are unable to feed raw materials quantitatively. When quantitative feeding is required, weighing equipment is required to weigh them separately, and then put them into the production equipment, which is time-consuming and labor-intensive. Therefore, a quantitative feeder for conveying plastic film raw materials is needed to solve this problem. Utility Model Content

[0005] Aiming at the above problems, the utility model provides a quantitative feeder for conveying plastic film raw materials to solve the above problems.

[0006] The utility model is implemented as follows: a quantitative feeder for conveying plastic film raw materials comprises a feed cylinder, the lower end of the feed cylinder is connected to a quantitative box, the right end face of the quantitative box is fixedly connected to two symmetrically distributed fixed rods, a rotating plate is rotatably connected between the two fixed rods, a first baffle is slidably connected to the upper side of the quantitative box, a second baffle is slidably connected to the lower side of the quantitative box, and the first baffle and the second baffle are both movably connected to the rotating plate;

[0007] An electronic scale is installed on the upper end surface of the second baffle.

[0008] In order to drive the first baffle plate and the second baffle plate to slide left and right when the rotating plate rotates, as a preferred quantitative feeder for conveying plastic film raw materials of the utility model, through holes are provided at the upper and lower ends of the rotating plate, and sliding grooves are provided at the front and rear end surfaces of the two through holes. Short columns are fixedly connected to the right sides of the front and rear end surfaces of the first baffle plate and the second baffle plate, and the four short columns are slidably connected to the four sliding grooves respectively.

[0009] In order to facilitate driving the rotating plate to rotate, as a preferred quantitative feeder for conveying plastic film raw materials of the utility model, a cylinder is hinged on the right end surface of the quantitative box, and the output end of the cylinder is hinged to the rotating plate.

[0010] In order to facilitate the opening of a chute in the through hole, as a preferred embodiment of the quantitative feeder for conveying plastic film raw materials of the utility model, the cross-section of the through hole is rectangular.

[0011] In order to prevent the raw material from remaining in the feeding cylinder, as a preferred embodiment of the quantitative feeding machine for conveying plastic film raw materials of the utility model, the lower end of the feeding cylinder is funnel-shaped.

[0012] In order to increase the service life and strength of the device, as a preferred quantitative feeder for conveying plastic film raw materials of the utility model, the material of the feed cylinder and the quantitative box are both aluminum alloy.

[0013] In order to facilitate the control of the equipment, as a preferred quantitative feeder for conveying plastic film raw materials of the utility model, the outer wall of the quantitative box is provided with a controller, and the cylinder and the electronic scale are both electrically connected to the controller.

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

[0015] The quantitative feeder for conveying plastic film raw materials inputs the raw materials into the feed barrel through the screw feeder, and the raw materials enter the quantitative box through the feed barrel and stay on the second baffle. When the electronic scale on the second baffle detects that the weight of the raw materials above reaches the set value, the cylinder pulls the rotating plate to rotate counterclockwise, and the counterclockwise rotation of the upper end of the rotating plate further drives the first baffle to slide to the left, thereby closing the feed inlet of the quantitative box, and the counterclockwise rotation of the lower end of the rotating plate further drives the second baffle to slide to the right, thereby opening the discharge port of the quantitative box, thereby discharging the raw materials in the quantitative box. After the raw materials are discharged, the cylinder pushes the rotating plate to rotate clockwise, and the clockwise rotation of the upper end of the rotating plate further drives the first baffle to slide to the right, thereby opening the feed inlet of the quantitative box, and the raw materials in the feed barrel enter the quantitative box, and the clockwise rotation of the lower end of the rotating plate further drives the second baffle to slide to the left, thereby closing the discharge port of the quantitative box, so that the raw materials fall on the electronic scale again for weighing, and this cycle is repeated. The raw materials are quantitatively weighed by an electronic scale, and then the rotating plate drives the first baffle and the second baffle to slide alternately to discharge the raw materials in the quantitative box, ensuring accurate material feeding.
