Description

Technical Field

[0001] The utility model relates to the field of bottle preform conveying devices, in particular to a bottle preform cooling and conveying device. Background Art

[0002] Bottle preforms are widely used in the packaging of daily necessities and daily chemicals, such as cosmetics, medicines, health care, beverages, etc. Bottle preforms are a typical injection molding product that is easy to transport and has good insulation properties. As an intermediate link in the production of plastic bottles, the quality of bottle preforms is directly related to the quality of the final product.

[0003] After the preforms are produced, they are conveyed by a conveyor to a collection frame. After being formed, the preforms are relatively hot. They collide and rub against each other on the conveyor belt, and hotter preforms are more likely to deform during collisions or friction. Existing preform cooling methods use cold air to directly blow air through the preforms, which results in uneven temperatures during cooling and can cause localized deformation. Therefore, it is essential to uniformly cool the preforms during conveyance. Utility Model Content

[0004] The utility model aims to provide a bottle preform cooling and conveying device to solve the problem of uneven temperature during bottle preform cooling.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a preform cooling and conveying device, comprising a support, a dust cover, and an inspection door, wherein the support is provided with a dust cover, the front and rear ends of the dust cover are provided with inspection doors, the inner side of the dust cover is provided with a conveying mechanism, and the top of the dust cover is provided with a cooling circulation mechanism;

[0006] The transmission mechanism includes a bracket, a transmission belt is provided on the inner side of the bracket, a motor is provided on the outer side of the bracket, a block is provided on the transmission belt, a cooling chamber is provided on the bracket, dust curtains are provided at the front and rear ends of the cooling chamber, an outer wall surface of the cooling chamber is affixed with a heat insulation layer, and the cooling chamber is fixed to the inner bottom of the dust cover through a connecting frame.

[0007] Furthermore, the cooling circulation mechanism includes a coolant storage tank, a coolant circulation pump is fixedly provided on the top of the coolant storage tank, the output end of the coolant circulation pump is connected to the liquid outlet pipe, the liquid outlet pipe is connected to the cooling pipe, the end of the cooling pipe is connected to the liquid return pipe, the liquid return pipe is connected to the air heat exchanger, the air heat exchanger is connected to the coolant storage tank through a connecting pipe, and the cooling pipe is arranged on the top inner side of the cooling chamber.

[0008] Furthermore, the inspection door is fixed to the front and rear ends of the dust cover by bolts, and an opening is provided on the inspection door.

[0009] Furthermore, the heat insulation layer is made of glass wool.

[0010] The utility model has the following beneficial effects:

[0011] The preform cooling and conveying device forms a low-temperature environment in the cooling chamber through the coordinated use of the cooling chamber of the conveying mechanism and the cooling pipe of the cooling circulation mechanism. The cooling chamber evenly cools the incoming preforms and avoids localized cooling deformation caused by direct air blowing. The cooling pipe continuously removes heat generated in the cooling chamber to maintain the low-temperature environment in the cooling chamber. The block of the conveying mechanism effectively prevents collision and friction during the conveying process. At the same time, the heat insulation layer of the conveying mechanism prevents the cooling chamber from being affected by changes in the external ambient temperature.

A cooling chamber 106 is provided on the bracket 103. The bottle preforms are cooled after entering the cooling chamber 106. Dust curtains 109 are provided at the front and rear ends of the cooling chamber 106 to prevent dust from entering. The outer wall 107 of the cooling chamber 106 is affixed with a heat insulation layer 108. The heat insulation layer 108 can prevent the cooling chamber from being affected by changes in external ambient temperature. The cooling chamber 106 is fixed to the inner bottom of the dust cover 4 through a connecting frame 105.

[0021] Among them, the cooling circulation mechanism 3 includes a coolant storage tank 305, and a coolant circulation pump 304 is fixedly arranged on the top of the coolant storage tank 305. The output end of the coolant circulation pump 304 is connected to the liquid outlet pipe 306, the liquid outlet pipe 306 is connected to the cooling pipe 307, the end of the cooling pipe 307 is connected to the return liquid pipe 301, the return liquid pipe 301 is connected to the air heat exchanger 302, the air heat exchanger 302 cools down the heated coolant, the air heat exchanger 302 is connected to the coolant storage tank 304 through the connecting pipe 303, the cooling pipe 307 is arranged on the top inner side of the cooling chamber 106, and the heat generated in the cooling chamber 106 rises and contacts the cooling pipe 307 to complete the heat exchange; the inspection door 2 is fixed to the front and rear ends of the dust cover 4 by bolts, and the inspection door 2 is provided with an opening 6; the insulation layer 108 is made of glass wool.

[0022] Working process: When the preform is being cooled and transported, the motor 101 is first started to ensure that the conveyor belt 102 is working properly, and then the coolant circulation pump 304 is started. After a period of time, when the temperature in the cooling chamber 106 drops,

[0023] The preforms to be cooled are sequentially placed between the blocks 104 of the conveyor belt 102. The preforms follow the conveyor belt 102 into the cooling chamber 106. The preforms are cooled in the low-temperature environment of the cooling chamber 106 to avoid local cooling deformation caused by direct air cooling. At the same time, the heat emitted by the preforms during cooling rises and contacts the cooling pipe 307 for heat exchange. The heated coolant in the cooling pipe 307 enters the air heat exchanger 302, exchanges heat with the outside air, and finally returns to the coolant storage tank 305 to continue the cooling cycle.
