Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, and in particular to an integrated device for blow molding of plastic bottles. Background Technology

[0002] Plastic bottles are common packaging containers, and blow molding is a core process in their production. Therefore, the performance of the blow molding equipment directly affects the molding quality and production efficiency of the plastic bottles. Currently, commercially available plastic bottle blow molding equipment still has many shortcomings in practical applications:

[0003] After the blow molding of plastic bottles is completed, the discharge of plastic bottles mostly relies on manual assistance or additional pushing equipment. The operation process is cumbersome and restricts the improvement of production efficiency. In addition, there are certain safety hazards when operating manually, and the use of additional equipment increases the cost of use and maintenance.

[0004] To address the aforementioned issues, this utility model document proposes an integrated device for blow molding of plastic bottles. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the reliance on manual labor or additional pushing equipment for unloading plastic bottles after blow molding, which results in a cumbersome process, low efficiency, safety hazards, and increased usage and maintenance costs. The proposed invention is an integrated device for blow molding plastic bottles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated blow molding machine for plastic bottles includes:

[0008] The base plate has four support rods fixedly installed on its top, and a top plate is fixedly installed on the top of the four support rods. Feed grooves are provided on both sides of the top plate for placing the material bars to be processed.

[0009] Two mold plates are provided, and mold grooves are provided on the side of the two mold plates that are close to each other. The two mold plates are slidably connected to the top of the base plate and the bottom of the top plate. When the two mold plates are closed, the mold grooves form a shaping space.

[0010] Two support pads are provided on the top of the base plate and located between the two mold plates. The support pads cooperate with the mold groove to support the blow-molded plastic bottle.

[0011] Two sets of rotating components are connected to the mold plate and the support pad. When the mold plate moves, the rotating components drive the support pad to flip, so as to complete the discharge of the plastic bottle.

[0012] An air blowing assembly for blowing air onto a material rod to shape it.

[0013] In one possible design, the rotating assembly includes a clearance groove formed on the top of the base plate, in which a rotating block is rotatably mounted, and the rotating block is fixedly connected to the bottom of the support pad.

[0014] In one possible design, the rotating assembly further includes an adjustment cavity formed at the bottom of the base plate. The rotating shaft of the rotating block extends into the adjustment cavity and is fixedly fitted with a first synchronous pulley. A first rotating shaft is rotatably mounted in the adjustment cavity, and a second synchronous pulley is fixedly fitted on the first rotating shaft. The second synchronous pulley and the first synchronous pulley are connected by a synchronous belt drive. A second rotating shaft is also rotatably mounted in the adjustment cavity, and a second bevel gear is fixedly fitted on the second rotating shaft. A first bevel gear is fixedly fitted on the first rotating shaft, and the first bevel gear meshes with the second bevel gear. A drive gear is fixedly mounted at the bottom end of the second rotating shaft.

[0015] In one possible design, the rotating assembly further includes a groove formed on the top of the base plate, a connecting plate fixedly installed on one side of the mold plate, and a rack fixedly installed at the bottom end of the connecting plate through the groove. The rack meshes with a drive gear. When the mold plate moves, the rack drives the drive gear to rotate, thereby causing the support pad to flip through the rotating assembly.

[0016] In one possible design, first cylinders are fixedly mounted on both sides of the base plate via brackets, and the piston rods of the two first cylinders are fixedly connected to one side of the adjacent mold plate to drive the mold plate to move.

[0017] In one possible design, the air blowing assembly includes a fixed bracket fixedly mounted on the top of the top plate, the fixed bracket being located between two feed troughs, and two air blowing pipes slidingly passing through the top of the fixed bracket, the bottom ends of the two air blowing pipes corresponding to the feed troughs, and air inlet ports provided on the two air blowing pipes; a connecting bracket fixedly mounted between the two air blowing pipes; and an mounting bracket fixedly mounted on the top of the fixed bracket, and a second cylinder fixedly mounted on the top of the mounting bracket, the piston rod of the second cylinder being fixedly connected to the top of the connecting bracket to drive the air blowing pipes to rise and fall.

[0018] In one possible design, two pneumatic grippers are fixedly installed at the bottom of the top plate, with the gripper ends of the two pneumatic grippers corresponding to the feed chute for gripping material bars.

[0019] In one possible design, a protective cover is fixedly installed on the bottom of the base plate, the protective cover being used to shield and protect the rack and drive gear.

[0020] In this application, during use, the two mold plates are kept far apart from each other under the action of the first cylinder, the two support pads are located on the top of the base plate and are in a flipped state, and the air blowing pipe is in a high position under the action of the second cylinder, with its bottom end maintaining a certain distance from the feed groove of the top plate.

[0021] Next, the material bar to be processed is fed through the feed troughs on both sides of the top plate using an external transfer device. Then, two pneumatic grippers hold and fix the material bar, ensuring that the material bar will not shift position during subsequent processing.

[0022] Then, the first cylinders on both sides of the base plate are activated. The piston rods of the two first cylinders extend synchronously, pushing the two mold plates closer together. As the mold plates move, the connecting plate on one side drives the rack to move horizontally along the slide groove, with the rack maintaining engagement with the drive gear. Because the mold plates are in the closing process, the movement of the rack drives the gear to rotate, thus achieving the rotation and reset of the corresponding support pad. When the two mold plates are not fully closed, the support pad is fully reset to a horizontal state, and the rack disengages from the corresponding drive gear.

[0023] Once the two mold plates have moved to their full closing position, the two mold slots on their closest sides close together to form two complete shaping spaces, where the two material bars are positioned. Simultaneously, the horizontal support plate engages with the bottom of the mold slot, providing bottom shaping and support for the subsequent blow molding of the material bars.

[0024] Next, the second cylinder at the top of the mounting bracket is activated. The piston rod of the second cylinder extends downward, which can push the connecting bracket to move downward along the inside of the mounting bracket. The two air blowing pipes are fixedly connected through the connecting bracket and can slide downward synchronously with the movement of the connecting bracket until the bottom end of the air blowing pipe passes through the feed chute and inserts into the corresponding material bar.

[0025] Then, high-pressure gas is introduced through an external air supply device and the air inlet at the top of the air blowing pipe. The high-pressure gas enters the inside of the material rod through the air blowing pipe, which allows the material rod to expand in the molding space formed by the mold groove and gradually fit into the inner wall of the mold groove, thus completing the blow molding process.

[0026] After blow molding is complete, the gas supply to the air inlet is shut off, and the second cylinder is activated. Its piston rod retracts upward, causing the connecting bracket and air blowing pipe to move upward synchronously, returning to the initial high position. Then, the first cylinder is activated, its piston rod retracts, pulling the two mold plates to separate. After the two mold plates have separated to a certain distance, the corresponding rack will re-engage with the drive gear, causing the drive gear to rotate in the opposite direction. The rotation of the drive gear, driven by the second bevel gear, the first bevel gear, the second synchronous pulley, and the first synchronous pulley, drives the rotating block to rotate synchronously, which in turn causes the support pad to flip synchronously, allowing the blow-molded plastic bottle to be tilted and pushed out from the support pad, completing the bottle unloading operation.

[0027] After the material is discharged, the device returns to its initial working state and can proceed to the next round of blow molding.

[0028] Beneficial effects: In this utility model, the integrated blow molding device for plastic bottles realizes automatic unloading after blow molding, which greatly improves production efficiency. After blow molding is completed, when the mold plate separates to a certain distance, the corresponding rack will mesh with the drive gear again, causing the support plate to automatically flip and tilt the molded plastic bottle out of the support plate. The entire unloading process does not require manual assistance or additional pushing mechanism, which simplifies the operation process, reduces labor costs, avoids the safety hazards, low efficiency or product damage that may occur with manual unloading, and speeds up the production pace.

[0029] In this invention, the integrated blow molding device for plastic bottles achieves rotation by moving the mold plate, eliminating the need for additional drive components to control the movement of the support plate and significantly simplifying the overall structure of the device. Simultaneously, this linkage ensures that the movement of the support plate is synchronized with the opening and closing of the mold plate. When the mold plate closes, the support plate can promptly return to a horizontal position, precisely matching the mold groove and providing stable shaping support for the bottom of the plastic bottle, thus significantly improving product molding quality.

[0030] In this invention, the integrated blow molding device for plastic bottles achieves reliable fixation of the material rod through pneumatic grippers. After the material rod to be processed is placed into the feeding trough, the pneumatic grippers can stably hold it, preventing the material rod from shifting position due to high-pressure gas impact or mold movement during the subsequent blow molding process. This positioning method directly ensures the precise position of the material rod in the molding space, further reducing molding defects caused by material shift and improving the consistency of the molding effect of the plastic bottle.

[0031] In this invention, the integrated blow molding device for plastic bottles features a synchronous design of the air blowing pipes that optimizes the blow molding process. The two air blowing pipes are fixedly connected by a connecting bracket and can be synchronously raised and lowered under the drive of a second cylinder, ensuring that the bottom of the air blowing pipe can accurately pass through the feeding groove and insert into the corresponding material rod. This synchronous action not only avoids the positional deviation that may occur when adjusting a single air blowing pipe, but also ensures that high-pressure gas is stably introduced into the material rod, allowing the material rod to expand uniformly in the molding space and conform to the inner wall of the mold groove, effectively ensuring the stability of the overall molding quality of the plastic bottle.

[0032] In this utility model, the integrated blow molding device for plastic bottles has a protective cover at the bottom of the base plate, which provides effective protection for the key components of the device. The protective cover can completely cover the rack and drive gear, preventing these transmission components from being directly exposed to the outside during long-term use, reducing the corrosion of components by dust and impurities, and preventing damage caused by external impacts. This protective design can extend the service life of components such as racks and gears, reduce the maintenance frequency and maintenance costs of the device, and ensure the long-term stable operation of the device.

[0033] In this invention, after the plastic bottle blow molding is completed, the mold plate separates and the support pad automatically discharges the material without the need for manual labor or additional equipment, thus avoiding safety hazards and reducing costs. The support pad moves in conjunction with the mold plate, requiring no additional drive. The pneumatic grippers fix the material to prevent displacement, and the air blowing pipe rises and falls synchronously to accurately complete the blowing. The protective cover protects the transmission components, extends the equipment life, reduces maintenance costs, and improves the overall performance of the equipment. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0042] In one embodiment: Refer to Figure 1-6 An integrated blow molding device includes: a base plate 1, a top plate 3, a mold plate 5, a support pad 7, a rotating component, and an air blowing component.

[0043] In this embodiment, the base plate 1 serves as the basic support structure of the device. Four support rods 2 are vertically fixed at the four corners of its top, and the top ends of the four support rods 2 jointly support and fix the top plate 3. Feed slots 4 are symmetrically opened on both sides of the top plate 3 for placing the material bars to be processed. Two pneumatic grippers 10 are fixedly installed at the bottom of the top plate 3 corresponding to the positions of the feed slots 4. When the material bars are transported into the feed slots 4 by external transfer equipment and transferred to the top of the mold slot, the corresponding pneumatic grippers 10 can clamp and fix the corresponding material bars, ensuring accurate positioning.

[0044] In this embodiment, the mold plate 5 adopts a double-plate opposing structure, with the two mold plates 5 slidably connected to the top of the base plate 1 and the bottom of the top plate 3, respectively. Each mold plate 5 has two symmetrically formed semi-circular mold grooves on the side closest to the other, forming a complete cylindrical shaping space when the two mold plates 5 are closed. The movement of the mold plates 5 is driven by the first cylinder 6 fixed to the supports on both sides of the base plate 1. The piston rod of the first cylinder 6 is fixedly connected to the side wall of the mold plate 5, thereby driving the two mold plates 5 to synchronously approach and separate.

[0045] In this embodiment, the support pad 7 is disposed on the top of the base plate 1 and located between the two mold plates 5, and its top shape matches the bottom contour of the mold groove. The bottom of each support pad 7 is flipped by a rotating assembly; wherein, the rotating assembly includes a corresponding clearance groove 8 opened on the top of the base plate 1, the clearance groove 8 is located at the edge of the base plate 1 and extends to the bottom of the adjacent support pad 7, and a rotating block 9 is rotatably installed in the clearance groove 8, the rotating block 9 is fixedly connected to the bottom of the support pad 7, and the rotating shaft of the rotating block 9 extends into the adjustment cavity 15 opened on the bottom of the base plate 1.

[0046] In this embodiment, the rotating assembly further includes a corresponding transmission mechanism, which includes a first rotating shaft 17 horizontally arranged within the adjustment cavity 15, with a second synchronous pulley 18 fixedly sleeved on the outer wall of the first rotating shaft 17; a first synchronous pulley 16 is fixed to the end of the rotating shaft of the rotating block 9, the two synchronous pulleys are of different sizes and are connected by a synchronous belt. A first bevel gear 19 is also fixedly sleeved on the outer wall of the first rotating shaft 17, and a second rotating shaft 20 is vertically rotatably arranged within the adjustment cavity 15, with a second bevel gear 21 fixedly sleeved on its outer wall, the first bevel gear 19 and the second bevel gear 21 meshing and transmitting power. The bottom end of the second rotating shaft 20 extends below the base plate 1 and is fixedly connected to a drive gear 22.

[0047] In this embodiment, the bottom end of the connecting plate 11 passes through the slide groove 13 at the top of the base plate 1 and is fixedly connected to a rack 12. The rack 12 is horizontally arranged and meshes with the adjacent drive gear 22. When the mold plate 5 moves, the rack 12 drives the drive gear 22 to rotate. Through the bevel gear set and synchronous belt transmission, the support pad 7 is finally flipped around the axis of the rotating block 9.

[0048] In this embodiment, the air blowing assembly is disposed on the top of the top plate 3, and includes a fixed bracket 23 and a mounting bracket 27. The fixed bracket 23 is located between the two feed troughs 4, and its top slidably passes through two air blowing pipes 24. The bottom ends of the air blowing pipes 24 are aligned with the feed troughs 4, and they are used to complete the air blowing process on the material rods. The two air blowing pipes 24 are fixedly connected by a connecting bracket 26. The mounting bracket 27 is fixedly installed on the top of the fixed bracket 23, and a second cylinder 28 is fixedly installed on its top. The piston rod of the second cylinder 28 is fixedly connected to the top of the connecting bracket 26 to realize the lifting and lowering drive of the two air blowing pipes 24.

[0049] This application can be used in the field of blow molding technology, or in other fields applicable to this application.

[0050] In another embodiment: Reference Figure 4 , 6 An integrated device for blow molding of plastic bottles, which is applied to the field of blow molding technology;

[0051] In this embodiment, a protective cover plate 14 is provided at the bottom of the base plate 1, which completely covers the meshing area of ​​the rack 12 and the drive gear 22, and can prevent foreign objects from entering the transmission system.

[0052] In this embodiment, each of the two air-blowing pipes 24 has an air inlet 25 near its top, which works in conjunction with an external air supply device to connect to an external air source to complete the air-blowing process.

[0053] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 6, the pneumatic gripper 10, and the second cylinder 28 are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0054] The working principle and usage process of this technical solution are as follows: During use, the two mold plates 5 are kept far apart from each other under the action of the first cylinder 6, the two support pads 7 are located on the top of the base plate 1 and are in a flipped state, and the air blowing pipe 24 is in a high position under the action of the second cylinder 28, with its bottom end maintaining a certain distance from the feed groove 4 of the top plate 3.

[0055] Next, the material bar to be processed is passed through the feed troughs 4 on both sides of the top plate 3 using an external transfer device. Then, two pneumatic grippers 10 clamp and fix the material bar to ensure that the material bar will not shift position during subsequent processing.

[0056] Then, the first cylinders 6 on both sides of the base plate 1 are activated. The piston rods of the two first cylinders 6 extend synchronously, pushing the two mold plates 5 closer together. As the mold plate 5 moves, the connecting plate 11 on one side can drive the rack 12 to move horizontally along the slide groove 13, with the rack 12 maintaining engagement with the drive gear 22. Because the mold plate 5 is in the closing process, the movement of the rack 12 can drive the gear 22 to rotate, thereby achieving the rotational reset of the corresponding support pad 7. When the two mold plates 5 are not fully closed, the support pad 7 is fully reset to a horizontal state, and the rack 12 disengages from the corresponding drive gear 22.

[0057] Once the two mold plates 5 have moved to their complete closing position, the two mold slots on their closest sides will close together to form two complete shaping spaces, at which point the two material bars will be positioned within their respective shaping spaces. Simultaneously, the horizontal support plate 7 will engage with the bottom of the mold slot, providing bottom shaping and support for the subsequent blow molding of the material bars.

[0058] Next, the second cylinder 28 at the top of the mounting bracket 27 is activated. The piston rod of the second cylinder 28 extends downward, which can push the connecting bracket 26 to move downward along the inside of the mounting bracket 27. The two air blowing pipes 24 are fixedly connected through the connecting bracket 26. They can slide downward synchronously with the movement of the connecting bracket 26 until the bottom end of the air blowing pipe 24 passes through the feed trough 4 and inserts into the corresponding material bar.

[0059] Then, high-pressure gas is introduced through an external air supply device and the air inlet 25 at the top of the air blowing pipe 24. The high-pressure gas enters the inside of the material rod through the air blowing pipe 24, which allows the material rod to expand in the molding space formed by the mold groove and gradually fit into the inner wall of the mold groove, thus completing the blow molding process.

[0060] After blow molding is completed, the gas supply to the air inlet 25 is shut off, and the second cylinder 28 is activated. Its piston rod retracts upward, causing the connecting bracket 26 and the air blowing pipe 24 to move upward synchronously, returning to the initial high position. Then, the first cylinder 6 is activated, and its piston rod retracts, pulling the two mold plates 5 to separate. After the two mold plates 5 have separated to a certain distance, the corresponding rack 12 will mesh with the drive gear 22 again, causing the drive gear 22 to rotate in the opposite direction. The rotation of the drive gear 22 can drive the rotating block 9 to rotate synchronously under the transmission of the second bevel gear 21, the first bevel gear 19, the second synchronous wheel 18, and the first synchronous wheel 16. This can then drive the support pad 7 to rotate synchronously, allowing the blow-molded plastic bottle to be tilted and pushed out from the support pad 7, completing the plastic bottle unloading operation.

[0061] After the material is discharged, the device returns to its initial working state and can proceed to the next round of blow molding.

[0062] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
