Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, specifically to a bottle unloading mechanism for a blow molding machine. Background Technology

[0002] In the large-scale production of plastic bottles, blow molding machines are the core equipment for plastic bottle molding. Through the process of "heating preform - high-pressure blowing molding - cooling and shaping", they process plastic raw materials such as PET and PP into bottles that meet specifications. A single high-speed blow molding machine can produce thousands to tens of thousands of plastic bottles per hour, which is a key link in ensuring the stability of the supply chain in industries such as beverages and daily chemicals.

[0003] Based on the above, the inventors have discovered the following problems: The current mainstream bottle unloading method for blow molding machines is mainly manual unloading. After the blow molding machine completes the molding process, the mold is opened, and the operator needs to manually remove the plastic bottle from the mold cavity and then put it into the conveyor belt. When carrying out large-scale production, multiple operators need to work in shifts, which significantly increases labor costs. Moreover, when manually removing bottles, the operator needs to frequently approach the high-temperature mold and high-speed moving parts, which can easily lead to burns or mechanical pinching accidents.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a bottle unloading mechanism for a blow molding machine in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a bottle unloading mechanism for a blow molding machine, so as to solve the problem mentioned in the background art that the current mainstream bottle unloading method of blow molding machines on the market is mainly manual assistance.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A bottle unloading mechanism for a blow molding machine includes a moving mechanism, a flipping mechanism, and a clamping mechanism. The moving mechanism includes a base, a movable seat slidably mounted on the upper end of the base, and first pneumatic telescopic rods inserted into both sides of the upper end of the movable seat. The flipping mechanism includes a mounting base, with both ends of the mounting base connected to the output ends of a pair of first pneumatic telescopic rods respectively. A flipping rod is rotatably connected inside the mounting base, and several connecting arms are slidably sleeved on the flipping rod. The clamping mechanism includes several clamping seats, with second pneumatic telescopic rods fixedly mounted on one side of each clamping seat. One end of each of the second pneumatic telescopic rods is connected to one end of a connecting arm. A pair of clamping rods is provided on the other side of each clamping seat, and an arc-shaped clamping block is bolted to the facing surfaces of each pair of clamping rods.

[0008] Furthermore, each clamping seat has a pair of wedge-shaped moving blocks slidably installed inside, and one end of each pair of wedge-shaped moving blocks is fixedly connected to a pair of clamping rods at their corresponding positions.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the wedge-shaped moving block inside the clamping seat is fixedly connected to the clamping rod. When the wedge-shaped moving block slides, it can directly drive the clamping rod to open and close, ensuring that the clamping rod moves synchronously, avoiding unilateral deviation that causes unstable bottle clamping, and improving clamping stability.

[0010] Furthermore, trapezoidal blocks are slidably installed between the inclined surfaces of the wedge-shaped moving blocks, and the output end of the second pneumatic telescopic rod extends through the clamping seat into the interior and is connected to one side of the trapezoidal block.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the second pneumatic telescopic rod pushes the trapezoidal block to move, and the trapezoidal block slides into contact with the inclined surface of the wedge-shaped moving block, which can convert the linear motion of the second pneumatic telescopic rod into the lateral motion of the wedge-shaped moving block, thereby driving the clamping rod to clamp or release the bottle.

[0012] Furthermore, a first servo motor is fixedly mounted on one end of the mounting base, and the output end of the first servo motor is connected to the flip rod via a transmission.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the first servo motor at one end of the mounting base provides stable power for the flipping rod, which can control the flipping angle and speed of the flipping rod, adapt to the turning requirements of the bottle in different bottle unloading scenarios, avoid the bottle falling off or colliding due to excessive flipping, and ensure a smooth bottle unloading process.

[0014] Furthermore, both the upper and lower sides of one end of the connecting arm are threaded with clamping bolts, and one end of the clamping bolt abuts against the outer side of the flipping rod.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the clamping bolt on the connecting arm abuts against the flipping rod. After the connecting arm slides along the flipping rod to a suitable position, the clamping bolt can be tightened to fix the connecting arm. This makes it easier to adjust the spacing of the clamping mechanism according to the bottle specifications or quantity, and improves the adaptability of the device.

[0016] Furthermore, a movable frame is embedded in the upper surface of the base, and a second servo motor is fixedly installed inside one end of the movable frame. A screw is sleeved on the output end of the second servo motor, and one end of the screw is rotatably connected to the other end of the movable frame.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the movable frame on the base provides installation support for the screw, the second servo motor drives the screw to rotate, providing power for the movement of the movable seat, the servo motor has high control precision, which can ensure the accurate movement position of the movable seat and adapt to the positioning requirements of the blow molding machine station.

[0018] Furthermore, a slider is threadedly connected to the screw, and the top end of the slider is fixedly connected to the bottom end of the movable seat.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the screw and the slider are connected by a thread, which can convert the rotational motion of the second servo motor into the linear motion of the slider, thereby driving the moving seat to move smoothly.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: the bottle unloading mechanism of the blow molding machine has a base that provides stable support for the whole, and the moving base can drive the flipping mechanism and the clamping mechanism to move laterally, which facilitates the clamping mechanism to move towards the processed bottle; the first pneumatic telescopic rod can drive the mounting base to rise and fall, which facilitates the removal of the bottle from the mold; the flipping rod of the flipping mechanism drives the connecting arm and the clamping mechanism to flip, which facilitates the flipping of the bottle in the mold to the other side, thereby achieving the unloading effect; the second pneumatic telescopic rod of the clamping mechanism drives the clamping base to move, and the clamping rod, together with the arc-shaped clamping block, clamps the bottle mouth from both sides. The arc design adapts to the shape of the bottle mouth to avoid damaging the bottle. The whole machine realizes precise clamping, flexible movement and flipping unloading of the blow molding machine bottle, improving unloading efficiency and safety. Attached Figure Description

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.

[0028] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a bottle unloading mechanism for a blow molding machine, including a moving mechanism 1, a flipping mechanism 2, and a clamping mechanism 3. The moving mechanism 1 includes a base 101, and a moving seat 103 is slidably mounted on the upper end of the base 101. First pneumatic telescopic rods 104 are inserted into both sides of the upper end of the moving seat 103. The flipping mechanism 2 includes a mounting base 201, and the two ends of the mounting base 201 are respectively connected to the output ends of a pair of first pneumatic telescopic rods 104. A flipping rod 202 is rotatably connected inside the mounting base 201, and several connecting arms 205 are slidably sleeved on the flipping rod 202. The clamping mechanism 3 includes several clamping seats 301, and a second pneumatic telescopic rod 302 is fixedly mounted on one side of each clamping seat 301. One end of each second pneumatic telescopic rod 302 is connected to one end of a connecting arm 205. A pair of clamping rods 303 are provided on the other side of each clamping seat 301. An arc-shaped clamping block 305 is bolted to the facing surfaces of each pair of clamping rods 303.

[0029] As an embodiment of this utility model, a pair of wedge-shaped moving blocks 304 are slidably installed inside the clamping base 301. One end of each pair of wedge-shaped moving blocks 304 is fixedly connected to a pair of clamping rods 303 at their corresponding positions. The wedge-shaped moving blocks 304 inside the clamping base 301 are fixedly connected to the clamping rods 303. When the wedge-shaped moving blocks 304 slide, they can directly drive the clamping rods 303 to open and close, ensuring that the clamping rods 303 move synchronously, avoiding unilateral deviation that causes unstable bottle clamping, and improving clamping stability.

[0030] As an embodiment of this utility model, trapezoidal blocks 306 are slidably installed between the inclined surfaces of the wedge-shaped moving blocks 304. The output end of the second pneumatic telescopic rod 302 extends through the clamping seat 301 into the interior and is connected to one side of the trapezoidal block 306. The second pneumatic telescopic rod 302 pushes the trapezoidal block 306 to move. The trapezoidal block 306 slides in contact with the inclined surface of the wedge-shaped moving blocks 304, which can convert the linear motion of the second pneumatic telescopic rod 302 into the lateral motion of the wedge-shaped moving blocks 304, thereby driving the clamping rod 303 to clamp or release the bottle.

[0031] As an embodiment of this utility model, a first servo motor 203 is fixedly installed at one end of the mounting base 201. The output end of the first servo motor 203 is connected to the flipping rod 202 for transmission. The first servo motor 203 at one end of the mounting base 201 provides stable power to the flipping rod 202, and can control the flipping angle and speed of the flipping rod 202 to adapt to the turning requirements of bottles in different bottle unloading scenarios, avoid the bottles falling off or colliding due to excessive flipping, and ensure a smooth bottle unloading process.

[0032] As an embodiment of this utility model, further, both the upper and lower sides of one end of the connecting arm 205 are threaded with abutting bolts 204. One end of the abutting bolt 204 abuts against the outer side of the flipping rod 202. The abutting bolt 204 on the connecting arm 205 abuts against the flipping rod 202. After the connecting arm 205 slides along the flipping rod 202 to a suitable position, the abutting bolt 204 can be tightened to fix the connecting arm 205. This makes it easy to adjust the spacing of the clamping mechanism 3 according to the bottle specifications or quantity, and improves the adaptability of the device.

[0033] As an embodiment of this utility model, a movable frame 102 is further embedded in the upper surface of the base 101. A second servo motor 106 is fixedly installed at one end of the interior of the movable frame 102. A screw 105 is sleeved on the output end of the second servo motor 106. One end of the screw 105 is rotatably connected to the other end of the interior of the movable frame 102. The movable frame 102 on the base 101 provides mounting support for the screw 105. The second servo motor 106 drives the screw 105 to rotate, providing power for the movement of the movable seat 103. The servo motor has high control precision, which can ensure that the movable seat 103 moves in a precise position, adapting to the positioning requirements of the blow molding machine station.

[0034] As an embodiment of this utility model, a slider 107 is threadedly connected to the screw 105. The top end of the slider 107 is fixedly connected to the bottom end of the movable seat 103. The screw 105 and the slider 107 are threadedly connected, which can convert the rotational motion of the second servo motor 106 into the linear motion of the slider 107, thereby driving the movable seat 103 to move smoothly.

[0035] Specifically, the working principle of the bottle unloading mechanism of this type of blow molding machine is as follows: During use, first, according to the specifications and spacing of the bottles to be unloaded, slide the connecting arm 205 along the flip rod 202 to adjust the position of the clamping mechanism 3, then tighten the abutment bolt 204 on the connecting arm 205 to fix it. Then, start the second servo motor 106 inside the moving frame 102; its output end drives the screw 105 to rotate. The screw 105 is threadedly connected to the slider 107, driving the slider 107 to move the moving seat 103 along the moving frame 102, causing the clamping mechanism 3 to move in alignment with the bottle mouth inside the blow molding machine mold. Subsequently, start the second pneumatic telescopic rod 302; its output end pushes the trapezoidal block 306 inside the clamping seat 301 to move. The trapezoidal block 306 slides in contact with the inclined surface of the wedge-shaped moving block 304, driving a pair of... The wedge-shaped moving blocks 304 slide towards each other, thereby closing the clamping rod 303 fixed to the wedge-shaped moving blocks 304, and clamping the bottle mouth through the arc-shaped clamping block 305; then the first pneumatic telescopic rod 104 on the moving base 103 is activated, and its output end pushes the mounting base 201 and the clamping mechanism 3 to rise and fall, thereby lifting the clamped bottle out of the mold. The first servo motor 203 starts and drives the flipping rod 202 to rotate, so that the connecting arm 205 and the clamping mechanism 3 drive the bottle to flip to the unloading direction; finally, the second servo motor 106 drives the moving base 103 to move to the unloading position again, the second pneumatic telescopic rod 302 retracts and drives the trapezoidal block 306 to reset, and the wedge-shaped moving blocks 304 slide in the opposite direction to release the clamping rod 303, completing the bottle unloading, and realizing the automated and precise bottle unloading operation.
