Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production and processing, and more particularly to a drying device for plastic bottle production. Background Technology

[0002] After plastic products are injection molded, they are rinsed and cleaned to reduce dirt left over from the processing. The usual cleaning method is to directly inject cleaning water for rinsing, and the rinsed plastic bottles are then dried.

[0003] Most plastic bottles are dried by air drying, which avoids the direct heating method and reduces the heat deformation of the plastic bottles. However, air drying is not a very effective way to remove moisture. Therefore, it is necessary to develop a new type of plastic bottle drying device. Utility Model Content

[0004] To address the technical deficiencies in the background art, this utility model proposes a drying device for plastic bottle production, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A drying device for plastic bottle production includes: a box body, a heat dissipation box, an exhaust box, a guide rail, a base, a conveyor belt, an exhaust vent, and an infrared terminal. The base is disposed inside the box body, and one vertical surface of the box body is open. One vertical surface of the base is attached to the edge of the opening on the side of the box body. The guide rail is embedded in the base and extends in an arc shape. Both ends of the guide rail extend to the vertical and outward-facing side of the base. The exhaust vent and the infrared terminal are respectively embedded at the bottom of the guide rail. The heat dissipation box is disposed outside the box body. At least two exhaust boxes are provided and fixed to opposite sides of the box body. At least two conveyor belts are provided, one for inlet and one for outlet. Each of the two conveyor belts has a corresponding lower edge of the opening of a guide rail.

[0006] A cover plate is provided on the top of the box body, the cover plate is horizontally positioned above the base, and there is a gap between them; a pipe is connected between the box body and the heat dissipation box, and the heat dissipation box is connected to the box body by the pipe.

[0007] The heat dissipation air box is connected to at least two guide air boxes by a pipe; the two guide air boxes are respectively fixed in the box body, and the openings of the two guide air boxes are respectively inclined, and the inclined surfaces of the two guide air boxes are respectively facing the guide rail.

[0008] Each of the aforementioned exhaust boxes is embedded in the box body and base on one side. An exhaust motor is installed inside the exhaust box. The exhaust motor of the exhaust box is connected to a collection box by a pipe. The side of the collection box away from the exhaust box is connected to the exhaust port by a pipe. Each of the aforementioned collection boxes is filled with an absorbent.

[0009] The guide rail has several openings at its bottom, and each opening is connected to a corresponding exhaust vent. An infrared tip is provided on the side adjacent to the exhaust vent, and the surface of the infrared tip is flush with the bottom surface of the guide rail. Several vertical rollers are provided on one vertical surface of the guide rail, and the rollers are arranged sequentially and extend along the extension direction of the guide rail. Each vertical roller has a protruding post embedded in the base at both its upper and lower ends.

[0010] The base contains a control unit, which is linearly electrically connected to the electronic components in the heat dissipation box, the exhaust box, and the infrared terminal. An electrical socket is provided on one side of the control unit, and the control unit is connected to a backup power source via the electrical socket.

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0018] like Figures 1 to 3 As shown, a drying device for plastic bottle production includes: a housing 1, a heat dissipation box 2, an exhaust box 3, a guide rail 4, a base 5, a conveyor belt 6, an exhaust vent 7, and an infrared terminal 8. The base 5 is disposed inside the housing 1, with one vertical surface of the housing 1 being open. One vertical surface of the base 5 is attached to the edge of the opening on the side of the housing 1. The guide rail 4 is embedded in the base 5 and extends in an arc shape, with both ends extending to the vertical and outward-facing side of the base 5. The exhaust vent 7 and the infrared terminal 8 are respectively embedded at the bottom of the guide rail 4. The heat dissipation box 2 is disposed outside the housing 1. At least two exhaust boxes 3 are provided and fixed to opposite sides of the housing 1. At least two conveyor belts 6 are provided, with one being an inlet conveyor belt and the other an outlet conveyor belt. Each of the two conveyor belts 6 is located at the lower edge of the opening of a corresponding guide rail 4.

[0019] Plastic bottles are arranged sequentially by an external feeding device and fed into an opening of guide rail 4. As the plastic bottles move along guide rail 4, infrared rays are projected through the infrared end 8 below. The infrared rays heat and evaporate the moisture inside the plastic bottles, forming water mist. The evaporated water mist is then drawn out through the exhaust vent 7 below to prevent accumulation and re-adhesion. After the plastic bottles are dried through the above steps, they are extruded in one direction again by the external feeding device, thus forming a sequential processing.

[0020] A cover plate 11 is provided above the housing 1. The cover plate 11 is horizontally positioned above the base 5 and a gap is provided between them. A pipe is connected between the housing 1 and the heat dissipation box 2, and the heat dissipation box 2 is connected to the housing 1 by a pipe.

[0021] With the above structure, it should be further explained that the cover plate 11 can prevent external dust from contaminating the bottle.

[0022] The heat dissipation box 2 is connected to at least two guide boxes 21 by a pipe; the two guide boxes 21 are respectively fixed inside the box body 1, and the openings of the two guide boxes 21 are respectively inclined, and the inclined surfaces of the two guide boxes 21 are respectively facing the guide rail 4.

[0023] With the above structure, it should be further explained that the heat dissipation box 2 is used to dissipate the excess heat generated during the infrared heating and drying process, so as to avoid the accumulation of heat and reduce the thermal deformation of the plastic bottle.

[0024] Each of the exhaust boxes 3 is embedded in the box body 1 and the base 5 on one side. An exhaust motor is installed in the exhaust box 3. The exhaust motor of the exhaust box 3 is connected to a collection box 71 by a pipe. The side of the collection box 71 away from the exhaust box 3 is connected to the exhaust port 7 by a pipe. Each collection box 71 is filled with an absorber.

[0025] With the above structure, it should be further explained that after the air containing moisture is drawn out from the exhaust box 3 through the exhaust port 7, in order to avoid the backflow of the air containing moisture, the air containing moisture drawn out by the exhaust motor will pass through the collection box 71. The absorber inside the collection box 71 will adsorb the moisture in the air, thereby achieving collection and treatment.

[0026] The guide rail 4 has several openings at its bottom, and each opening of the guide rail 4 is connected to a corresponding exhaust vent 7. An infrared end 8 is provided on the side adjacent to the exhaust vent 7, and the surface of the infrared end 8 is flush with the bottom surface of the guide rail 4. A number of vertical rollers 52 are provided on one vertical surface of the guide rail 4, and the number of vertical rollers 52 are arranged in sequence and extend along the extension direction of the guide rail 4. Each vertical roller 52 has a protruding post at its upper and lower ends embedded in the base 5.

[0027] With the above structure, it should be further explained that this invention uses infrared radiation to heat fine water vapor. When the emission frequency of infrared radiation matches the inherent frequency of molecular motion in the material, it causes strong vibration and rotation of the material molecules, resulting in intense collisions and friction between molecules within the material, generating heat and rapidly raising the temperature. This drives water and other liquid molecules out of the material, achieving the purpose of drying. Since the absorption spectrum of infrared radiation by materials is mostly distributed in the far-infrared region, especially organic matter, polymers, and water, which have a wide absorption band in the far-infrared region, drying using far-infrared radiation is superior to drying using near-infrared radiation.

[0028] The base 5 is equipped with a control unit 50, which is linearly electrically connected to the electronic components in the heat dissipation box 2, the exhaust box 3, and the infrared terminal 8. An electrical socket is provided on one side of the control unit 50, and the control unit 50 is connected to a backup power supply 51 through the electrical socket. The backup power supply 51 is linearly electrically connected to an external power source.

[0029] With the above structure, it should be further explained that the control unit 50 of this utility model is composed of several circuit boards, and the control unit 50 is connected to external control equipment such as computers via conduits.

[0030] Each of the conveyor belts 6 is connected to an external drive motor; at least two blocking bars 61 are provided above each of the conveyor belts 6, and one end of each of the two blocking bars 61 is fixed to the edge of the opening of the guide rail 4.

[0031] With the above structure, it should be further explained that the conveyor belt 6 of this utility model is composed of a track and several rollers. The rollers are arranged in sequence and housed inside the track. The rollers are connected by a belt. A motor drives one of the rollers, which in turn drives the belt. The belt drives the other rollers. The rollers rolling synchronously drive the track in one direction, thereby moving the plastic bottle placed on the track in one direction.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
