Technical Field

[0001] The utility model belongs to the technical field of plastic bottle production, and specifically relates to an automatic feeding machine for plastic bottle production. Background Art

[0002] A blow molding machine is a machine that can blow plastic granules (softened into liquid) or finished bottle blanks into bottles through certain process means. Blow molding machines are convenient and fast, with a large molding volume. After their appearance, they have replaced most manual bottle blowing and are adopted by most companies. At present, during the use of traditional fully automatic blow molding machines for plastic bottle production, the raw materials are generally fed manually, resulting in poor production efficiency and unable to meet production needs. Therefore, a feeding machine that can automatically feed plastic granules has been designed on the market.

[0003] Although the existing automatic feeding machines for plastic bottle production can replace the function of manual automatic feeding, when a variety of different types of plastic particles are required to produce plastic bottles, although the melting chamber of the existing blow molding machine is equipped with a stirring component that can stir and mix a variety of different types of plastic particles, if the stirring is not thorough, it may directly affect the quality of the produced plastic bottles. In view of this, an automatic feeding machine that can pre-mix a variety of different types of plastic particles is proposed to improve the uniformity of mixing. Utility Model Content

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: an automatic feeding machine for plastic bottle production, comprising: a feeding barrel, an upper end of one side of the feeding barrel is connected to a feeding hopper, and a lower end of the side of the feeding barrel away from the feeding hopper is connected to a discharge pipe; a rotating shaft, rotatably connected in the feeding barrel; a spiral propulsion blade, fixedly connected to the rotating shaft; a motor, fixedly connected to one side of the feeding barrel, and an end of the rotating shaft close to the motor is fixedly connected to the output end of the motor; a lifting plate, spirally and equidistantly fixedly connected to the rotating shaft.

[0006] In order to further improve the mixing effect of the plastic particles, a plurality of rows of disturbance rods are fixedly connected in an equidistant and staggered manner in the upper hopper.

[0007] In order to facilitate the removal of dust in the plastic particles, further, a first opening is opened on the upper side of the loading barrel, an electrostatic adsorption plate is installed at the first opening, and an electrostatic generator is fixedly installed on the electrostatic adsorption plate.

[0008] In order to facilitate the cleaning of dust on the electrostatic adsorption plate, further, the electrostatic adsorption plate is rotatably connected to the loading barrel via a rotating shaft.

[0009] In order to facilitate the preheating effect on the plastic particles, further, a second opening is opened on the lower side of the upper barrel, and an electric heating plate is installed at the second opening.

[0010] In order to facilitate the control of the temperature of the plastic particles, further, a temperature controller electrically connected to the electric heating plate is installed on the loading barrel.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model uses the feeding barrel, rotating shaft, spiral propulsion blades, motor, lifting plate and other components in coordination. In the process of feeding plastic bottle raw materials, when a variety of different types of raw materials are needed to produce plastic bottles, the feeding machine can lift up the various types of raw materials during the transportation process, so that the various types of raw materials can move irregularly in the feeding barrel, so that the various types of plastic particles can be pre-mixed, so that when the plastic particles enter the heating bin of the blow molding machine through the discharge pipe for melting and mixing, the various types of plastic particles are mixed evenly, which effectively guarantees the quality of the subsequent plastic bottles produced.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4 An automatic feeding machine for producing plastic bottles comprises: a feeding barrel 1, an upper end of one side of the feeding barrel 1 is connected to a feeding hopper 101, and a lower end of the side of the feeding barrel 1 away from the feeding hopper 101 is connected to a discharge pipe 102; a rotating shaft 2, rotatably connected in the feeding barrel 1; a spiral propulsion blade 201, fixedly connected to the rotating shaft 2; a motor 202, fixedly connected to one side of the feeding barrel 1, and one end of the rotating shaft 2 close to the motor 202 is fixedly connected to the output end of the motor 202; a lifting plate 203, fixedly connected to the rotating shaft 2 in a spiral and equidistant manner.

[0022] When the blow molding machine is used to extrude the plastic bottles, the plastic particles need to be transported into the blow molding machine by the feeder for heating and melting. When a plurality of different types of plastic particles are needed to produce plastic bottles, the staff can pour the various types of plastic particles into the upper hopper 101 according to a certain proportion, and then the plastic particles will enter the upper barrel 1 through the upper hopper 101, and then the motor 202 can be started, and the motor 202 will drive the spiral propulsion blade 201 to rotate through the rotating shaft 2, and then the plastic particles will be pushed by the spiral propulsion blade 201 to discharge. The plastic particles are transported on one side of the material pipe 102. When the rotating shaft 2 drives the plastic particles to be transported through the spiral propulsion blade 201, the rotating shaft 2 will also drive the lifting plate 203 to rotate. When the plastic particles move to the position of the lifting plate 203, various types of plastic particles will be lifted by the lifting plate 203, so that various types of plastic particles can be pre-mixed. When the plastic particles pass through the discharge pipe 102 and enter the heating chamber of the blow molding machine for melting and mixing, the various types of plastic particles are mixed evenly, which effectively guarantees the quality of the subsequent plastic bottles produced.

[0023] Embodiment 2:

[0024] Reference Figure 1-Figure 4, an automatic feeding machine for plastic bottle production is basically the same as Example 1, and further: a plurality of rows of disturbance rods 1011 are equidistantly and staggeredly fixedly connected in the feeding hopper 101. Through the arrangement of the plurality of rows of disturbance rods 1011, when the staff pours a plurality of different types of plastic particles into the feeding hopper 101, the various types of plastic particles will move irregularly under the action of the staggered disturbance rods 1011, thereby playing a role of preliminary mixing of the various types of plastic particles, improving the effect of subsequent mixing by the lifting plate 203, thereby ensuring the quality of plastic bottle production.

[0025] A first opening is provided on the upper side of the loading barrel 1, and an electrostatic adsorption plate 4 is installed at the first opening. An electrostatic generator 401 is fixedly installed on the electrostatic adsorption plate 4. When the spiral propulsion blade 201 is conveying the plastic particles, the electrostatic generator 401 can be started, and the static electricity generated by the electrostatic generator 401 will be applied to the electrostatic adsorption plate 4, so that the electrostatic adsorption plate 4 generates static electricity. Then, when the lifting plate 203 lifts the plastic particles, the electrostatic adsorption plate 4 can absorb the dust mixed in the plastic particles, thereby improving the cleanliness of the plastic particles and improving the quality of subsequent plastic bottle production. In order to avoid Plastic particles are adsorbed by static electricity, and the strength of the static electricity applied by the static generator 401 to the static adsorption plate 4 can be controlled so that it can only adsorb lighter dust. It should be noted that the loading barrel 1, the rotating shaft 2, the spiral propulsion blade 201 and the lifting plate 203 can all be made of anti-static materials, such as anti-static PC material, so as to prevent the loading barrel 1, the rotating shaft 2, the spiral propulsion blade 201 and the lifting plate 203 from generating static electricity, causing the dust to adhere to the surface of the loading barrel 1, the rotating shaft 2, the spiral propulsion blade 201 and the lifting plate 203 and mix with the plastic particles, thereby effectively ensuring the dust cleaning effect.

[0026] The electrostatic adsorption plate 4 is rotatably connected to the loading barrel 1 via a rotating shaft. By rotatably connecting the electrostatic adsorption plate 4 to the loading barrel 1, when the loading of the plastic particles is completed, the electrostatic adsorption plate 4 can be opened, and then the staff can clean the dust adsorbed on the electrostatic adsorption plate 4, thereby improving the subsequent cleaning efficiency of the dust in the plastic particles.

[0027] Embodiment 3:

[0028] Reference Figure 1-Figure 4, an automatic feeding machine for producing plastic bottles, which is basically the same as Example 2, and further: a second opening is opened on the lower side of the feeding barrel 1, and an electric heating plate 3 is installed at the second opening. By arranging the electric heating plate 3 on the lower side of the feeding barrel 1, when the spiral propulsion blade 201 pushes the plastic particles to the position of the discharge pipe 102, the electric heating plate 3 can preheat the plastic particles, so that when the plastic particles enter the blow molding machine through the discharge pipe 102, the heating time of the plastic particles can be reduced, so that the plastic particles can be melted quickly, and the efficiency of plastic bottle production is effectively improved.

[0029] A temperature controller 103 electrically connected to the electric heating plate 3 is installed on the loading barrel 1. Through the setting of the temperature controller 103, the temperature generated by the electric heating plate 3 can be controlled, so as to facilitate better heating of the plastic particles and avoid the plastic particles from melting due to excessive heating temperature, thereby adhering to the loading barrel 1 and affecting the feeding effect of the plastic particles.
