Description

Technical Field

[0001] This invention belongs to the technical field of plastic molding and processing equipment, specifically a novel preform loading mechanism for a fully automatic wide-mouth blow molding machine. Background Technology

[0002] In the plastic packaging industry, fully automatic wide-mouth blow molding machines are the core equipment for producing containers such as wide-mouth bottles and cans. The preform loading mechanism, as a crucial upstream station of the blow molding machine, directly determines the overall production efficiency and finished product qualification rate.

[0003] However, most common preform loading mechanisms have fixed-size clamping and positioning structures that can only accommodate preforms of a single specification. When producing wide-mouth preforms of different diameters, manual disassembly and replacement are required, which is cumbersome and time-consuming, resulting in low production efficiency and high production costs for enterprises. Summary of the Invention

[0004] The purpose of this invention is to provide a novel preforming mechanism for a fully automatic wide-mouth blow molding machine in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A novel loading mechanism for a fully automatic wide-mouth blow molding machine includes a base plate, a box base plate fixedly connected to the front of the base plate, a loading bracket and a loading bracket arranged sequentially from front to back on the top of the base plate, a protective box arranged on the top of the box base plate, and a loading adjustment component arranged on the inner side of the protective box.

[0006] By adopting the above technical solution, during the operation of the equipment, the adjusting screw is driven by the adjusting motor to rotate. Through the threaded connection between the adjusting screw and the adjusting ring, the adjusting ring is raised or lowered. The adjusting ring pulls or pushes the tie rod, causing the adjusting column to move within the adjusting groove. This, in turn, moves the limiting column through the connecting rod, changing the distance between the supporting column and the limiting column. The clamping diameter can be adjusted according to the diameter of the wide-mouth bottle preform, adapting to the preform loading operation of wide-mouth bottle preforms of different sizes. This significantly improves the versatility and applicability of the equipment, reduces production changeover costs, and increases production efficiency.

[0007] In a preferred embodiment, the upper blank adjustment assembly includes a rotary motor, a lower mounting plate, a support column, a middle mounting plate, an upper mounting plate, an adjustment motor, an adjustment screw, an adjustment ring, a pull rod, a pull rod slider, an adjustment groove, a sliding column, an adjustment column, a connecting rod, a limiting column, and a translation slider; The rotating motor is fixedly mounted above the bottom of the housing base plate. The output end of the rotating motor is fixedly connected to a lower mounting plate. Multiple support columns are fixedly mounted above the lower mounting plate. The top of each support column passes through a middle mounting plate and extends to the top of the middle mounting plate, where it is fixedly connected to an upper mounting plate. Adjustment grooves are provided circumferentially above the support columns, the middle mounting plate, and the upper mounting plate. Sliding columns are provided on the inner sides of each adjustment groove. Translation sliders are slidably connected to the outer sides of the sliding columns in the lower and upper mounting plates. Adjustment columns are fixedly mounted at the top and bottom of the translation sliders located on the lower and upper mounting plates. A pull rod slider is slidably connected to the outer side of the sliding column inside the middle mounting plate. A pull rod is rotatably connected to the back of the pull rod slider. An adjustment groove is rotatably connected above the pull rod. An adjustment motor is fixedly mounted on the top of the upper mounting plate. An adjustment screw is fixedly connected to the output end of the adjustment motor. An adjustment ring is threaded onto the outer side of the adjustment screw. A connecting rod is fixedly connected to the outer side of the adjustment column. A limit post is fixedly connected to the front end of the connecting rod.

[0008] By adopting the above technical solution, the adjustment screw is rotated by adjusting the motor, which drives the adjustment ring. The adjustment ring pulls or pushes the tie rod, which drives the adjustment column. Through the connecting rod, the limit column is moved, changing the distance between the support column and the limit column. The clamping diameter can be adjusted according to the diameter of the wide-mouth bottle preform, adapting to the preform loading operation of wide-mouth bottle preforms of different sizes. This greatly improves the versatility and applicability of the equipment, reduces production changeover costs, and improves production efficiency.

[0009] In a preferred embodiment, an embryo-retrieving frame and an embryo-releasing frame are respectively provided above the embryo-retrieving support and the embryo-releasing support. An oppositely arranged movable cylinder is installed in both the embryo-retrieving frame and the embryo-releasing frame. The output end of the movable cylinder is fixedly connected to the embryo-retrieving cylinder, and an embryo-retrieving cylinder is provided below the embryo-retrieving cylinder.

[0010] By adopting the above technical solution, and by setting a moving cylinder and a preform picking cylinder in the preform picking and placing frame, it is easy to pick up and place the preform.

[0011] In a preferred embodiment, both sides of the embryo-removing mounting frame and the embryo-releasing mounting frame are provided with embryo-removing cylinder grooves, and an embryo-removing cylinder is slidably connected to the inner side of the embryo-removing cylinder groove.

[0012] By adopting the above technical solution and opening the slide groove of the embryo-removing cylinder, the embryo-removing cylinder can slide stably, thus maintaining the stable operation of the equipment.

[0013] In a preferred embodiment, an embryo-lifting motor is also provided on the inner bottom side of the embryo-retrieving support, and an embryo-lifting screw is fixedly connected to the output end of the embryo-lifting motor. An embryo-lifting robotic arm is threadedly connected to the outer side of the embryo-lifting screw.

[0014] By adopting the above technical solution, the preform motor is started, which drives the preform screw to rotate, thereby driving the preform lifting robot arm to rise. The preform lifting robot arm can drive the preform placed in the preform adjustment component to rise.

[0015] In a preferred embodiment, the inner side of the embryo-retrieving support is provided with a sliding groove for an embryo-lifting robotic arm, and an embryo-lifting robotic arm is slidably connected to the inner side of the sliding groove.

[0016] By adopting the above technical solution, and by opening a sliding groove for the embryo-lifting robotic arm on the inner side of the embryo-retrieving support, the stable operation of the embryo-lifting robotic arm can be ensured, thus ensuring the stable operation of the equipment.

[0017] In a preferred embodiment, the protective enclosure is provided with rotatable access doors on both the front end and both sides.

[0018] By adopting the above technical solution, it is convenient to manually place the preform into the preform adjustment component, and it is also convenient to repair and maintain the equipment.

[0019] In a preferred embodiment, a conveyor belt is provided between the embryo placement support and the embryo removal support.

[0020] By adopting the above technical solution, and by setting a conveyor belt between the preform placement support and the preform removal support, the preform can be horizontally transferred from the front end of the equipment to the rear end.

[0021] In a preferred embodiment, the adjusting post and the limiting post are installed in triangular sections.

[0022] By adopting the above technical solution, and by installing the adjusting column and the limiting column in a triangular shape, the preform can be limited, ensuring the stability of the preform's ascent.

[0023] In a preferred embodiment, the rotating motor and the adjusting motor are servo motors; the rotating motor is used to drive the entire upper blank adjusting assembly to rotate and position.

[0024] By adopting the above technical solution, the servo motor provides high-precision speed control and positioning performance, making the rotation positioning almost without deviation.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: During operation, the adjusting screw is driven by the adjusting motor to rotate. The adjusting screw is connected to the adjusting ring by a thread, which causes the adjusting ring to rise or fall. The adjusting ring pulls or pushes the rod, which moves the adjusting column within the adjusting groove. This, in turn, moves the limiting column via the connecting rod, changing the distance between the supporting column and the limiting column. The clamping diameter can be adjusted according to the diameter of the wide-mouth bottle preform, adapting to the loading of wide-mouth bottle preforms of different sizes. This significantly improves the versatility and applicability of the equipment and reduces production changeover costs. Attached Figure Description

[0030] During operation, the adjusting screw 307 is driven to rotate by the adjusting motor 306. The adjusting screw 307 is connected to the adjusting ring 308 by a thread, causing the adjusting ring 308 to rise or fall. The adjusting ring 308 pulls or pushes the pull rod 309, causing the adjusting column 3013 to move within the adjusting groove 3011. This, in turn, moves the limiting column 3015 via the connecting rod 3014, changing the distance between the supporting column 303 and the limiting column 3015. The clamping diameter can be adjusted according to the diameter of the wide-mouth bottle preform, adapting to the preform loading operation of wide-mouth bottle preforms of different sizes. This significantly improves the versatility and applicability of the equipment, reduces production changeover costs, and increases production efficiency.

[0031] The upper blank adjustment assembly 3 includes a rotation motor 301, a lower mounting plate 302, a support column 303, a middle mounting plate 304, an upper mounting plate 305, an adjustment motor 306, an adjustment screw 307, an adjustment ring 308, a pull rod 309, a pull rod slider 3010, an adjustment slide groove 3011, a slide column 3012, an adjustment column 3013, a connecting rod 3014, a limit column 3015, and a translation slider 3016; The rotating motor 301 is fixedly installed above the bottom of the bottom plate 2 of the housing. The output end of the rotating motor 301 is fixedly connected to the lower mounting plate 302. Multiple support columns 303 are fixedly installed above the lower mounting plate 302. The top of the support columns 303 passes through the middle mounting plate 304 and extends to the top of the middle mounting plate 304 to be fixedly connected to the upper mounting plate 305, so that the overall structure is stable and reliable. The support column 303, the middle mounting plate 304, and the upper mounting plate 305 are all provided with circumferentially oriented adjustment grooves 3011. The inner side of each adjustment groove 3011 is provided with a sliding column 3012. The outer side of the sliding column 3012 in the lower mounting plate 302 and the upper mounting plate 305 is slidably connected to a translation slider 3016. The top and bottom of the translation slider 3016 in the lower mounting plate 302 and the upper mounting plate 305 are fixedly provided with adjustment columns 3013. The outer side of the sliding column 3012 on the inner side of the middle mounting plate 304 is slidably connected to a pull rod slider 3010. The back side of the pull rod slider 3010 is rotatably connected to a pull rod 309. The upper side of the pull rod 309 is rotatably connected to the adjustment groove 3011 to ensure that the adjustment column 3013 can slide stably when adjusted. An adjusting motor 306 is fixedly installed on the top of the upper mounting plate 305. An adjusting screw 307 is fixedly connected to the output end of the adjusting motor 306. An adjusting ring 308 is threadedly connected to the outer side of the adjusting screw 307. A connecting rod 3014 is fixedly connected to the outer side of the adjusting column 3013. A limit post 3015 is fixedly connected to the front end of the connecting rod 3014. The clamping diameter can be adjusted according to the diameter of the wide-mouth bottle preform.

[0032] By adjusting the motor 306 to drive the adjusting screw 307 to rotate, the adjusting ring 308 is driven. The adjusting ring 308 pulls or pushes the pull rod 309, which in turn drives the adjusting column 3013. Through the connecting rod 3014, the limiting column 3015 is moved, thus changing the distance between the supporting column 303 and the limiting column 3015. The clamping diameter can be adjusted according to the diameter of the wide-mouth bottle preform, adapting to the preform loading operation of wide-mouth bottle preforms of different sizes. This greatly improves the versatility and applicability of the equipment, reduces production changeover costs, and increases production efficiency.

[0033] Above the preform receiving support 5 and the preform placement support 4, respectively, are preform receiving mounting frames 7 and 6. Each preform receiving mounting frame 7 and 6 contains a movable cylinder 8 arranged in opposite directions. The output end of the movable cylinder 8 is fixedly connected to a preform receiving cylinder 9, and a preform receiving cylinder 10 is located below the preform receiving cylinder 9. By installing the movable cylinder 8 and the preform receiving cylinder 9 within the preform receiving mounting frames 7 and 6, the receiving and placement of preforms can be easily achieved.

[0034] Both sides of the embryo-receiving mounting frame 7 and the embryo-releasing mounting frame 6 are provided with embryo-receiving cylinder grooves 15, and embryo-receiving cylinders 9 are slidably connected to the inner side of the embryo-receiving cylinder grooves 15. By providing embryo-receiving cylinder grooves 15, the embryo-receiving cylinder 9 can slide stably, maintaining stable operation of the equipment.

[0035] An inoculum receiving support 5 is also provided with an inoculum loading motor 11 on the inner side of its bottom. The output end of the inoculum loading motor 11 is fixedly connected to an inoculum loading screw 12, and the outer side of the inoculum loading screw 12 is threadedly connected to an inoculum lifting robotic arm 13. By starting the inoculum loading motor 11, the inoculum loading screw 12 is driven to rotate, thereby driving the inoculum lifting robotic arm 13 to rise. Through the inoculum lifting robotic arm 13, the bottle inoculum placed in the inoculum loading adjustment assembly 3 can be lifted.

[0036] The embryo-retrieving support 5 has an embryo-lifting robotic arm groove 14 on its inner side, and an embryo-lifting robotic arm 13 is slidably connected to the inner side of the embryo-lifting robotic arm groove 14. By opening the embryo-lifting robotic arm groove 14 on the inner side of the embryo-retrieving support 5, the stable operation of the embryo-lifting robotic arm 13 can be ensured, thus ensuring the stable operation of the equipment.

[0037] The protective housing 16 has rotatable inspection doors 17 on its front and both sides. This facilitates manual placement of preforms into the preform adjustment assembly 3 and also makes equipment maintenance and repair convenient.

[0038] A conveyor belt 18 is installed between the preform placement support 4 and the preform removal support 5. By installing the conveyor belt 18 between the preform placement support 4 and the preform removal support 5, the preform can be horizontally transferred from the front end of the equipment to the rear end.

[0039] The adjusting column 3013 and the limiting column 3015 are installed in a triangular shape. By installing the adjusting column 3013 and the limiting column 3015 in a triangular shape, the preform can be limited, ensuring the stability of the preform's ascent.

[0040] Both the rotary motor 301 and the adjusting motor 306 are servo motors. The rotary motor 301 is used to drive the entire upper blank adjusting assembly 3 for rotational positioning. The servo motor provides high-precision speed control and positioning performance, making the rotational positioning almost without deviation.

[0041] The implementation principle of a novel preform loading mechanism for a fully automatic wide-mouth blow molding machine according to the present invention is as follows: First, the preform is placed in the preform loading adjustment assembly 3. Then, the adjustment motor 306 is started, which drives the adjustment screw 307 to rotate. Through the threaded connection between the adjustment screw 307 and the adjustment ring 308, the adjustment ring 308 is driven to rise or fall. The adjustment ring 308 pulls or pushes the pull rod 309, which drives the adjustment column 3013 to move within the adjustment groove 3011. This, in turn, drives the limiting column 3015 to move through the connecting rod 3014, thereby changing the distance between the support column 303 and the limiting column 3015. The clamping diameter can be adjusted according to the diameter of the wide-mouth preform, adapting to the preform loading operation of wide-mouth preforms of different sizes. This greatly improves the versatility and applicability of the equipment, reduces production changeover costs, and improves production efficiency.

[0042] The preform motor 11 is started, which drives the preform screw 12 to rotate. The preform screw 12 drives the preform lifting robot arm 13 to slide and rise in the preform lifting robot arm slide groove 14, thereby driving the preform in the preform adjustment assembly 3 to rise. Then, the moving cylinder 8 is started, which drives the preform picking cylinder 9 to directly above the preform. The preform picking cylinder 9 is started, and the preform is adsorbed by the preform picking cylinder 10 and placed on the conveyor belt 18 for transportation.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
