Description

Technical Field

[0001] This utility model relates to the technical field of high-density polyethylene bottles for solid pharmaceuticals, specifically a molding machine for producing antistatic bottles. Background Technology

[0002] High-density polyethylene (HDPE) bottles for oral solid dosage forms are containers specifically designed for holding oral solid dosage forms such as tablets and capsules. They possess antistatic properties. In the prior art, patent publication number CN 118876396 A discloses a molding apparatus for a food-grade plastic bottle, including a fixed base; a mold disposed on one side of the fixed base; a blow molding mechanism for blowing gas into the preform; a negative pressure mechanism for providing a negative pressure environment to the outside of the preform; and a lifting mechanism for controlling the up-and-down movement of the blow molding mechanism and the negative pressure mechanism. This food-grade plastic bottle molding apparatus, through the cooperation of the blow molding mechanism and the negative pressure mechanism, can provide positive and negative pressure to both sides of the preform. On the one hand, this ensures more even pressure on both sides of the multi-layer preform, preventing excessive pressure on the inner layers due to isolated pressure; on the other hand... The pressure is distributed by providing pressure from both sides, which reduces the air pressure inside the preform and avoids uneven thickness caused by excessive pressure. This results in a more uniform wall thickness of the molded plastic bottle and improves the quality of the plastic bottle. However, this device blow-moldes HDPE bottle preforms through a mold cavity. Since HDPE bottles are circular, when the two molds separate longitudinally, the blow-molded HDPE bottle may get stuck in the blow molding cavity, which is not conducive to the automatic unloading of HDPE bottles. Therefore, we propose a molding machine for antistatic bottle production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a molding machine for producing antistatic bottles. This device can automatically extrude and discharge HDPE bottles in two blow molding cavities simultaneously by using the spring compression and reset force through transmission elements, thereby avoiding the phenomenon of HDPE bottle discharge jamming in the blow molding cavity of the mold and effectively solving the problems in the background art.

The springs are movably sleeved with the outer ends of the adjacent telescopic columns. The feeding seats are located inside the adjacent arc-shaped grooves. This device can automatically squeeze and feed HDPE bottles in the mold cavities of the two blow molding molds at the same time through the transmission element and the spring compression and reset elasticity, so as to avoid the phenomenon of molded HDPE bottles getting stuck in the mold cavity.

[0006] Furthermore, a microcontroller is provided at the front end of the molded shell, and the input terminal of the microcontroller is electrically connected to an external power supply, which facilitates the control of the electrical components inside the device.

The guide grooves are all connected to the adjacent inner cavities. The slide rods are slidably connected inside the guide grooves. The slide rods are all fixedly connected to the adjacent feeding seats, so that the feeding seats in the molding machine for producing antistatic bottles can automatically and completely slide into the corresponding arc-shaped grooves.

[0008] Furthermore, both the rear mold and the front mold are equipped with cooling pipes in the middle to cool down the HDPE bottles blow-molded in the antistatic bottle production molding machine.

[0009] Furthermore, the upper front end of the molded shell is provided with a connecting frame, and the upper end of the connecting frame is provided with a vertical moving seat through the telescopic end of the electro-hydraulic push rod. The lower side of the vertical moving seat is provided with two air pumps, and the air outlets of the air pumps are fixedly connected to the upper ends of the vertically adjacent blow molding heads.

The upper side of the vertical moving seat is provided with two symmetrically distributed guide rods, and the upper ends of the guide rods are slidably connected to the circular holes opened on the connecting frame to adjust the vertical position of the blow molding heads in the molding machine for antistatic bottle production.

[0010] Furthermore, the front wall of the molding shell is provided with an electro-hydraulic push rod II. The input end of the electro-hydraulic push rod II is electrically connected to the output end of the microcontroller. A guide rod II is slidably connected in the circular hole II opened in the front wall of the molding shell. The front end of the guide rod II and the telescopic end of the electro-hydraulic push rod II are fixedly connected to the front side of the front mold, so as to adjust the position of the front mold in the molding machine for antistatic bottle production.

[0011] Furthermore, a laser sensor is provided on the upper side of the vertical moving base, and a laser sensor is provided on the upper front side of the molding shell. Both laser sensor one and laser sensor two are bidirectionally electrically connected to the microcontroller to measure and upload the moving distance of the front mold and the vertical moving base of the molding machine for antistatic bottle production.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The molding machine for producing this antistatic bottle has the following advantages:

[0013] When using a molding machine for producing antistatic bottles, components such as arc grooves, springs, feeding seats, guide slides, and slide rods are used.

[0019] 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.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a molding machine for producing antistatic bottles, including a molding shell 1, a rear mold 3 at the upper front end of the molding shell 1, a front mold 4 installed at the front end of the rear mold 3, two blow molding heads 11 installed at the upper end of the molding shell 1, the blow molding heads 11 being fitted with the rear mold 3 and the front mold 4, a microcontroller 2 at the front end of the molding shell 1, the input end of the microcontroller 2 being electrically connected to an external power source, cooling pipes 6 being provided in the middle of both the rear mold 3 and the front mold 4, a connecting frame 7 at the upper front end of the molding shell 1, a vertical moving seat 9 at the upper end of the connecting frame 7 via the telescopic end of an electro-hydraulic push rod 8, two air pumps 10 at the lower side of the vertical moving seat 9, the air outlets of the air pumps 10 being fixedly connected to the upper ends of the vertically adjacent blow molding heads 11, the electro-hydraulic push rod 8 and the air pumps 1 The input terminals of the 0 are all electrically connected to the output terminals of the microcontroller 2. Two symmetrically distributed guide rods 12 are provided on the upper side of the vertical shifter 9. The upper ends of the guide rods 12 are slidably connected to the circular holes 1 on the connecting frame 7. An electro-hydraulic push rod 14 is provided on the front wall of the molding shell 1. The input terminal of the electro-hydraulic push rod 14 is electrically connected to the output terminal of the microcontroller 2. A guide rod 16 is slidably connected inside the circular holes 2 on the front wall of the molding shell 1. The front end of the guide rod 16 and the telescopic end of the electro-hydraulic push rod 14 are fixedly connected to the front side of the front mold 4. A laser sensor 13 is provided on the upper side of the vertical shifter 9, and a laser sensor 15 is provided on the upper front side of the molding shell 1. Both laser sensors 13 and 15 are bidirectionally electrically connected to the microcontroller 2. The device is used for HDPE bottle blowing. During molding, the upper and lower ends of the cooling pipe 6 are connected to the external water inlet and outlet pipes respectively via flexible hoses. Then, the HDPE preform is placed into the top opening of the cavity of the rear mold 3 via an external feeding device. Subsequently, the microcontroller 2 activates the electro-hydraulic actuator 14, causing its extension end to move the front mold 4 longitudinally backward, aligning it with the rear mold 3. During this process, the microcontroller 2 activates the laser sensor 15, which emits a light signal that illuminates the protruding part on the right front side of the rear mold 3 and reflects back to its initial position. Based on the propagation time and speed of the light signal, the longitudinal movement distance of the rear mold 3 is obtained. The laser sensor 15 then transmits the measured result to the microcontroller 2 as an electrical signal. The microcontroller 2 adjusts the electro-hydraulic actuator 14 according to the measured result. The control mechanism moves the rear side of the front mold 4 to contact the front side of the rear mold 3. The front mold 4 drives the guide rod 16 to slide adaptively along the corresponding circular hole 2. At this time, the top openings of the mold cavities of the front mold 4 and the rear mold 3 cooperate to fix the upper end of the HDPE bottle preform. Then, the microcontroller 2 activates the electro-hydraulic push rod 8, causing its telescopic end to drive the vertical moving seat 9 to move vertically downward. The vertical moving seat 9 drives the corresponding blow molding head 11 to move vertically downward through the air pump 10. During this process, the microcontroller 2 activates the laser sensor 13. The laser sensor 13 emits a light signal to illuminate the top wall of the connecting frame 7 and reflects it back to the initial position. Based on the same principle, the vertical movement distance of the vertical moving seat 9 is measured. The laser sensor 13 transmits the measured result to the microcontroller 2 in the form of an electrical signal.The microcontroller 2 controls the extension distance of the telescopic end of the electro-hydraulic push rod 8 based on the measured results, so that the blow molding head 11 is inserted vertically downward into the corresponding HDPE bottle preform. During this process, the vertical shift seat 9 drives the guide rod 12 to slide adaptively along the corresponding circular hole. Then, the microcontroller 2 starts the air pump 10, which causes the external gas to enter the blow molding head 11 at a certain downward pressure. The blow molding head 11 blow molds the HDPE bottle preform, causing it to expand and fit into the mold cavities of the front mold 4 and the rear mold 3, thus realizing the blow molding operation of the HDPE bottle. Subsequently, water flows into the cooling pipe 6 from the upper end through the external water inlet and outlet pipes and flows out from the lower end through the external hose. The water in the cooling pipe 6 uses heat transfer to cool and lower the blow-molded HDPE bottle, accelerating its blow molding speed. The system also includes a feeding mechanism 5.

[0021] The unloading mechanism 5 includes an arc-shaped groove 51, an inner cavity 52, a telescopic column 53, a spring 54, and an unloading seat 55. The inner cavities 52 are respectively opened in the middle of the rear mold 3 and the front mold 4. The middle of the mold cavity of the rear mold 3 and the front mold 4 is provided with an arc-shaped groove 51, which is connected to the adjacent inner cavity 52. ​​The left and right ends of the two inner cavities 52 facing away from the wall are provided with unloading seats 55 through vertically symmetrically distributed telescopic columns 53 and springs 54. The springs 54 are movably sleeved with the outer ends of the adjacent telescopic columns 53. The unloading seats 55 are located inside the adjacent arc-shaped grooves 51. The unloading mechanism 5 also includes a guide groove 56 and a slide rod. 57. Guide grooves 56 are respectively opened at the left and right ends of the rear mold 3 and the front mold 4. The guide grooves 56 are all connected to the adjacent inner cavities 52. The guide grooves 56 are all slidably connected to the interior of the guide grooves 56. The guide rods 57 are all fixedly connected to the adjacent blanking seats 55. During the longitudinal approach of the front mold 4 to the rear mold 3, when the two are close to each other to a certain extent, the relative inner ends of the two longitudinally adjacent guide rods 57 contact each other. As the front mold 4 continues to approach the rear mold 3, the relative inner ends of the two longitudinally adjacent guide rods 57 are squeezed against each other, thereby causing the guide rods 57 to drive the blanking along the corresponding guide grooves 56. The seat 55 moves into the adjacent arc-shaped groove 51, and the telescopic end of the telescopic column 53 and the spring 54 both retract. When the rear side of the front mold 4 contacts the front side of the rear mold 3, the slide rod 57 drives the corresponding unloading seat 55 to fully penetrate into the corresponding arc-shaped groove 51. The outer arc surface of the unloading seat 55 fits against the inner wall of the arc-shaped groove 51, thus preventing the unloading seat 55 from being pressed and moving during the subsequent HDPE bottle preform blow molding process. After the HDPE bottle is blow molded, the single-chip microcomputer 2 controls the electro-hydraulic push rod 14 to move the front mold 4 forward. As the front mold 4 moves forward, the two longitudinally adjacent slide rods 57 move in opposite directions. As the pressure between the inner ends gradually decreases, the compression and reset force of the spring 54 causes the unloading seat 55 to move away from the adjacent arc groove 51. By moving the unloading seat 55 away from the arc groove 51, the blow-molded HDPE bottle in the mold cavity is squeezed and separated, allowing the blow-molded HDPE bottle to automatically fall and be unloaded through the separation gap between the front mold 4 and the rear mold 3. This device, through the transmission element, uses the compression and reset force of the spring to automatically squeeze and unload the HDPE bottle in the mold cavity of the two blow molding cavities at the same time, avoiding the phenomenon of the molded HDPE bottle getting stuck in the blow molding cavity.

[0022] The working principle of the molding machine for producing antistatic bottles provided by this utility model is as follows: When using the device for HDPE bottle blow molding, the upper and lower ends of the cooling pipe 6 are connected to the external water inlet and outlet pipes respectively through flexible hoses. Then, the HDPE bottle preform is placed into the top opening of the mold cavity of the rear mold 3 through the external feeding device. Subsequently, the microcontroller 2 activates the electro-hydraulic push rod 14, causing its telescopic end to drive the front mold 4 to move longitudinally backward, thereby aligning and contacting the rear mold 3 longitudinally. During this process, the microcontroller 2 activates the laser sensor 15. The laser sensor 15 emits a light signal that irradiates the protruding part on the right side of the front end of the rear mold 3 and reflects it back to the initial position. Based on the propagation time and speed of the light signal, the longitudinal movement distance of the rear mold 3 is obtained. Subsequently, the laser sensor 15... 5. The measured results are transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 adjusts the electro-hydraulic push rod 14 according to the measured results, so that the rear side of the front mold 4 just moves to contact the front side of the rear mold 3. The front mold 4 drives the guide rod 16 to slide adaptively along the corresponding circular hole 2. At this time, the top openings of the mold cavities of the front mold 4 and the rear mold 3 cooperate with each other to fix the upper end of the HDPE bottle preform. As the front mold 4 moves longitudinally closer to the rear mold 3, when the two get close to each other to a certain extent, the relative inner ends of the two longitudinally adjacent slide rods 57 contact each other. As the front mold 4 continues to move closer to the rear mold 3, the relative inner ends of the two longitudinally adjacent slide rods 57 squeeze each other, so that the slide rods 57 move along the corresponding guide groove 5. 6. The feeding seat 55 moves into the adjacent arc groove 51. The telescopic end of the telescopic column 53 and the spring 54 retract. When the rear side of the current mold 4 contacts the front side of the rear mold 3, the slide rod 57 drives the corresponding feeding seat 55 to fully penetrate into the corresponding arc groove 51. The outer arc surface of the feeding seat 55 fits against the inner wall of the arc groove 51, thus preventing the feeding seat 55 from moving due to pressure during the later HDPE bottle preform blow molding process. Then, the microcontroller 2 starts the electro-hydraulic push rod 8, causing its telescopic end to drive the vertical moving seat 9 to move vertically downward. The vertical moving seat 9 drives the corresponding blow molding head 11 to move vertically downward through the air pump 10. During this process, the microcontroller 2 starts the laser sensor 13, which emits a light signal to illuminate the top of the connecting frame 7. The laser sensor 13 reflects the image back to its initial position. Following the same principle, the vertical movement distance of the vertical moving seat 9 is measured. The laser sensor 13 transmits the measured result to the microcontroller 2 as an electrical signal. The microcontroller 2 controls the extension distance of the telescopic end of the electro-hydraulic push rod 8 based on the measured result, ensuring that the blow molding head 11 is inserted vertically downwards into the corresponding HDPE bottle preform. During this process, the vertical moving seat 9 drives the guide rod 12 to slide adaptively along the corresponding circular hole. Subsequently, the microcontroller 2 starts the air pump 10. The air pump 10 operates, causing external gas to enter the blow molding head 11 at a certain downward pressure. The blow molding head 11 blow molds the HDPE bottle preform, causing it to expand and fit into the mold cavities of the front mold 4 and the rear mold 3, thus realizing the HDPE bottle blow molding operation.Subsequently, water flows into the cooling pipe 6 from the top through external inlet and outlet pipes and out through external hoses. The water in the cooling pipe 6 cools the blow-molded HDPE bottle via heat transfer, accelerating the blow molding process. After the HDPE bottle is blow-molded, the microcontroller 2 controls the electro-hydraulic push rod 14 to move the front mold 4 forward. As the front mold 4 moves forward, the pressure between the relatively inner ends of the two longitudinally adjacent slide rods 57 gradually decreases. The compression and reset force of the spring 54 causes the unloading seat 55 to move away from the adjacent arc groove 51. This movement of the unloading seat 55 away from the arc groove 51 squeezes and separates the blow-molded HDPE bottle from the mold cavity, allowing the blow-molded HDPE bottle to automatically drop through the separation gap between the front mold 4 and the rear mold 3.

[0023] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a COP8CBE9, the electro-hydraulic actuator 8 and the electro-hydraulic actuator 14 can both be DYZW integral straight micro electro-hydraulic actuators, the air pump 10 can be an FKY8006 high positive pressure brushless air pump, and the laser sensor 13 and the laser sensor 15 can both be WH-LRF laser rangefinders. The microcontroller 2 controls the operation of the electro-hydraulic actuator 8, the air pump 10, the laser sensor 13, the electro-hydraulic actuator 14 and the laser sensor 15 using methods commonly used in the prior art.
