Description

Technical Field

[0001] This utility model relates to the technical field of preform conveying devices, specifically a preform conveying device with an auxiliary cooling structure. Background Technology

[0002] Preform conveying systems are devices used for the automated transport of preforms on production lines, and are widely used in the packaging industries of beverages, food, and pharmaceuticals. These systems typically include conveyor belts, guide rails, and drive systems, and can efficiently and stably transport preforms from injection molding machines to subsequent equipment such as blow molding machines and filling machines.

[0003] However, in the existing preform conveying device, the preforms are placed onto the device by a robot arm as soon as they are taken out of the injection molding machine mold. The cooling time is short, and the preforms have relatively thick walls, making them difficult to cool completely. Therefore, directly receiving the preforms through the conveying device can lead to deformation of the preforms that have not been fully cooled, thus reducing the quality of preform production. Therefore, we propose a preform conveying device with an auxiliary cooling structure. Utility Model Content

[0004] The purpose of this invention is to provide a preform conveying device with an auxiliary cooling structure to solve the problem mentioned in the background art that the current preform conveying devices on the market lack an auxiliary cooling structure and that the preform walls are relatively thick, making it difficult to cool them completely.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a preform conveying device with an auxiliary cooling structure, comprising a frame and a support platform. Electric slide rails are installed on both sides of the frame, and a movable frame is slidably connected to the inner side of the electric slide rails. A lifting block is slidably sleeved in the built-in groove of the movable frame. The support platform is fixedly connected above the lifting block. A protective cover is installed on the outer side of the frame, and a cooling mechanism is installed on the top of the protective cover. The cooling mechanism includes a first conduit, an air compressor pump, a nozzle, and a second conduit. An air compressor pump is installed above the protective cover.

[0006] Preferably, a first conduit is connected to one side of the air compressor pump, and a second conduit is connected to the end of the first conduit away from the air compressor pump.

[0007] Preferably, nozzles are evenly spaced below the second conduit, and a sleeve is fitted onto the outside of the first conduit, with a cooling chamber inside the sleeve.

[0008] Preferably, one side of the sleeve is connected to an outlet pipe and an inlet pipe, and both the outlet pipe and the inlet pipe are connected to the cooling chamber.

[0009] Preferably, sleeves are installed at equal intervals above the support platform, fans are installed at the two ends of the protective cover, and a support mechanism is installed on the inner side of the movable frame near the lifting block, and the support mechanism is connected to the lifting block.

[0010] Preferably, the support mechanism includes a screw, a first gear, a second gear, a drive shaft, and a motor, and the screw is mounted in the built-in slot of the movable frame via a bearing.

[0011] Preferably, one end of the screw is fixedly connected to a first gear, one side of the first gear is meshed with a second gear, and a drive shaft is mounted on the lower part of the movable frame via a bearing.

[0012] Preferably, the drive shaft and the second gear are fixedly connected, a motor connected to the drive shaft via a coupling is installed on one side of the movable frame, and the lifting block and the screw are threadedly connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Equipped with a cooling mechanism and a cooling chamber, when the preform is removed and placed on the sleeve, the electric slide rail is activated to move the moving frame into the protective cover. At the same time, the air compressor pump is activated to draw in the surrounding air and compress it. Then, the airflow is delivered to the second conduit through the first conduit. Meanwhile, the liquid inlet pipe delivers external coolant into the cooling chamber. The cooling chamber cools the airflow passing through the first conduit. The cooled airflow is sprayed out through the nozzle below the second conduit, blowing the cooled air onto the preform, so that the preform that is not completely cooled is cooled again. At the same time, the fan rotates to expel the heat inside the protective cover, promote air circulation, improve cooling efficiency, and improve the working quality of the preform conveying device.

[0015] 2. Equipped with a support mechanism, the starting motor drives the transmission shaft and the second gear to rotate. The second gear then drives the first gear to rotate, and subsequently the first gear drives the screw to rotate, causing the screw to engage with the lifting block. The lifting block then moves up or down on the outside of the screw. At the same time, the lifting block drives both ends of the support platform to move up and down, adjusting the height of the support platform to meet different preform conveying needs and improve the practicality of the preform conveying device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 and Figure 6 This utility model provides a technical solution: a bottle preform conveying device with an auxiliary cooling structure, including a frame 1 and a support platform 4. Electric slide rails 2 are installed on both sides of the frame 1. A movable frame 8 is slidably connected to the inner side of the electric slide rails 2. A protective cover 3 is installed on the outer side of the frame 1. Sleeves 5 are evenly distributed on the top of the support platform 4.

[0026] Please see Figures 1-5The top of the protective cover 3 is equipped with a cooling mechanism 6, which includes a first conduit 601, an air compressor pump 602, a nozzle 603, and a second conduit 604. The air compressor pump 602 is installed above the protective cover 3. One side of the air compressor pump 602 is connected to the first conduit 601. The end of the first conduit 601 away from the air compressor pump 602 is connected to the second conduit 604. The nozzles 603 are evenly spaced below the second conduit 604. A sleeve 7 is fitted to the outside of the first conduit 601. A cooling chamber 10 is opened inside the sleeve 7. One side of the sleeve 7 is connected to an outlet pipe 11 and an inlet pipe 12, and both the outlet pipe 11 and the inlet pipe 12 are connected to the cooling chamber 10. Fans 14 are installed at the two ends of the protective cover 3. The second conduit 604 is square-shaped. The cooling chamber 10 is annular inside the sleeve 7.

[0027] In practice, since the preforms are placed onto the preform conveying device by a robot arm as soon as they are taken out of the injection molding machine mold, the preforms have thick walls and are not easy to cool completely. Therefore, directly receiving them through the conveying device will cause the preforms that are not fully cooled to deform, reducing the production quality of the preforms. When the preforms are taken out and placed on the sleeve 5, the electric slide rail 2 is activated to move the moving frame 8 into the protective cover 3. At the same time, the air compressor pump 602 is activated to draw in the surrounding air and compress it. Then, the airflow is delivered to the second conduit 604 through the first conduit 601. At the same time, the liquid inlet pipe 12 delivers external coolant into the cooling chamber 10. The cooling chamber 10 cools the airflow passing through the first conduit 601. The cooled airflow is sprayed out through the nozzle 603 below the second conduit 604 and blown onto the preforms, so that the preforms that are not fully cooled can be cooled again. At the same time, the fan 14 rotates to expel the heat inside the protective cover 3, promotes air circulation, improves cooling efficiency, and improves the working quality of the preform conveying device.

[0028] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7A lifting block 13 is slidably sleeved in the built-in groove of the movable frame 8. The support platform 4 is fixedly connected above the lifting block 13. A support mechanism 9 is installed on the inner side of the movable frame 8 near the lifting block 13 and is connected to the lifting block 13. The support mechanism 9 includes a screw 901, a first gear 902, a second gear 903, a transmission shaft 904, and a motor 905. The screw 901 is installed in the built-in groove of the movable frame 8 through a bearing, and one end of the screw 901 is fixedly connected to... There is a first gear 902, and a second gear 903 is meshed with one side of the first gear 902. A transmission shaft 904 is installed below the moving frame 8 via a bearing. The transmission shaft 904 and the second gear 903 are fixedly sleeved together. A motor 905 is installed on one side of the moving frame 8 and is connected to the transmission shaft 904 via a coupling. The lifting block 13 is threadedly sleeved with the screw 901. There are two of each of the first gear 902, the second gear 903, and the screw 901.

[0029] In practical implementation, since the height of the conveying platform of most preform conveying devices is fixed, it is not convenient to adjust it according to the preform placement requirements, which affects the preform conveying operation. Before the conveying operation, the motor 905 can be started to drive the transmission shaft 904 and the second gear 903 to rotate. The second gear 903 then drives the first gear 902 to rotate. Subsequently, the first gear 902 drives the screw 901 to rotate, so that the screw 901 and the lifting block 13 are threadedly engaged. Then the lifting block 13 moves up or down on the outside of the screw 901. At the same time, the lifting block 13 drives the two ends of the support platform 4 to move up and down, adjusting the height of the support platform 4 to meet different preform conveying requirements and improve the practicality of the preform conveying device.

[0030] Working principle: When using the preform conveying device with auxiliary cooling structure, firstly, according to the conveying requirements, the height of the support platform 4 is adjusted by the support mechanism 9. Then, the preform is taken out and placed on the outside of the sleeve 5. Subsequently, the electric slide rail 2 drives the moving frame 8 to move, so that the support platform 4 moves the preform. After the preform moves into the protective cover 3, the preform is cooled again by the cooling mechanism 6 and the cooling chamber 10, which improves the practicality of the preform conveying device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
