Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic bottle conveying, and particularly relates to an integrated suspension conveying device for plastic bottle production. BACKGROUND

[0002] On a modern plastic bottle production line, the stability and efficiency of the suspension conveying device directly affect the production capacity and product quality of the entire production line. At present, the widely used plastic bottle suspension conveying technology mainly relies on a double-rail structure, that is, a gap is formed between two parallel rails, and the neck part of the plastic bottle is clamped into the gap to achieve the suspension and continuous conveying of the bottle body.

[0003] However, with the increasing demand for product diversification in the market, the production line needs to frequently switch different specifications and different bottle diameters of plastic bottles. The limitations of the existing suspension conveying device gradually become apparent. When changing the bottle type, because the neck sizes of different diameters are different, the distance between the double rails must be manually adjusted to ensure that the neck can be stably clamped and not fall off or be stuck. This adjustment process not only needs to be stopped, but also needs to be accurately calibrated with measuring tools, which takes a long time and seriously affects the continuous operation capacity and overall efficiency of the production line. In addition, the suspension conveying device is usually driven by a driving device to run the conveying chain. The chain will inevitably have the phenomenon of elongation or uneven tension due to the influence of multiple factors such as continuous load, mechanical wear, environmental temperature change and lubrication condition fluctuation during long-term operation. The dynamic change of the chain tension will cause unstable conveying speed, bottle body running jitter and even position deviation. SUMMARY

[0004] Therefore, the present application provides an integrated suspension conveying device for plastic bottle production, which can overcome the shortcomings of the prior art that the existing suspension conveying device needs to be stopped to manually adjust the distance between the double rails when conveying plastic bottles of different bottle types, which is troublesome and affects the production efficiency, and the tension of the conveying chain will dynamically change to cause unstable conveying.

[0005] The technical solution is as follows: An integrated overhead conveyor for plastic bottle production includes: a base plate; an overhead conveyor mounted on the top of the base plate; a controller mounted on the top of the base plate; a mounting frame rotatably mounted on the conveyor chain of the overhead conveyor; a lifting frame slidably connected to the mounting frame; a lifting cylinder connected to the bottom of the lifting frame; a sliding sleeve slidably connected to the lifting cylinder, with symmetrical through holes at the top; a first spring connected at both ends to the lifting cylinder and the sliding sleeve respectively; positioning plates circumferentially spaced and connected to the bottom of the sliding sleeve; an air bladder connected to the inner wall of the sliding sleeve; a lifting assembly mounted on the mounting frame for driving the lifting frame to lift; a power supply assembly mounted on the conveyor chain for supplying power to the lifting assembly; a control assembly mounted on the lifting frame for controlling the expansion or contraction of the air bladder; and an adjustment assembly mounted on the guide rail of the overhead conveyor for adjusting the tension of the conveyor chain.

[0006] Preferably, the lifting assembly includes: a drive motor mounted on the mounting frame; and a lead screw rotatably connected to the mounting frame, the top of which is connected to the output shaft of the drive motor, and the lead screw is threadedly connected to the lifting frame.

[0007] Preferably, the power supply assembly includes: a pantograph mounted on top of the conveyor chain; and a conductive copper plate mounted on the inner top of the guide rail, wherein the conductive copper plate is in contact with the pantograph.

[0008] Preferably, the control assembly includes: a vertical rod connected to the bottom of the lifting frame, the vertical rod passing through the top of the sliding sleeve, and the bottom of the vertical rod connected to the top of the airbag; and a piston plate connected to the vertical rod, and the piston plate making contact and sealing with the inner wall of the sliding sleeve.

[0009] Preferably, the adjustment component includes: a sliding frame slidably connected to the guide rail, with the conveyor chain sliding through the interior of the sliding frame; an electric push rod mounted on the top of the guide rail, with the sliding frame connected to the telescopic rod of the electric push rod; and a detection mechanism disposed inside the sliding frame for detecting the tension of the conveyor chain.

[0010] Preferably, the detection mechanism includes: a slider, which is slidably connected to the inside of the sliding frame; a rotating wheel, which is rotatably connected to the slider and is in contact with the conveyor chain; a pressure sensor, which is installed on the side of the slider; and a second spring, which is connected at both ends to the pressure sensor and the sliding frame, respectively.

[0011] Preferably, the system also includes a positioning assembly, which comprises: a fixed plate symmetrically connected to both sides of the mounting frame; a swing frame symmetrically rotatably connected to the fixed plate; rollers rotatably connected to the swing frame; a third spring connected to the two swing frames at both ends; and a short rod symmetrically connected to both sides of the lifting frame, the short rod sliding through the side of the fixed plate and engaging with the swing frame.

[0012] Preferably, the device also includes: a fixing block symmetrically connected to the top of the mounting frame; and a stop bar symmetrically connected to the conveyor chain, with the stop bar in contact with the fixing block.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention drives the lifting frame to descend through the lifting component, which can drive the positioning plate to move downward and press against the outer wall of the plastic bottle. At the same time, the control component will push the airbag to move downward and enter the bottle and expand, so as to achieve a tight fit between the inner wall of the bottle. This process does not require manual adjustment of the guide rail spacing. The positioning plate and the airbag cooperate with each other inside and outside, which can automatically adapt to the bottle neck of different diameters, significantly shorten the bottle type change time, and improve production continuity and efficiency.

[0014] 2. The present invention can monitor the tension of the conveyor chain in real time through the detection mechanism. When the pressure sensor detects abnormal tension, the controller will control the electric push rod to drive the sliding frame to move, thereby automatically adjusting the chain tension. This mechanism effectively counteracts the elongation or slack of the chain caused by wear or temperature changes, ensuring stable conveying speed and reducing bottle shaking and position deviation.

[0015] 3. Through the positioning component, the present invention can center the plastic bottle by pushing it with rollers when the lifting frame descends, ensuring that the airbag is accurately inserted into the bottle mouth. At the same time, when the conveyor chain tilts, the fixing block and the stop bar can limit the rotation angle of the mounting frame and avoid collision between adjacent plastic bottles. The two work together to ensure the gripping accuracy and enhance the safety of the equipment in complex paths. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example: An integrated overhead conveyor system for plastic bottle production, such as... Figures 1-5 As shown, the system includes a base plate 1, a suspended conveyor 2, a controller 3, a mounting frame 4, a lifting frame 5, a lifting cylinder 6, a sliding sleeve 7, a first spring 8, a positioning plate 9, an airbag 10, a lifting assembly, a power supply assembly, a control assembly, and an adjustment assembly. The suspended conveyor 2 is mounted on the top of the base plate 1, and the controller 3 is mounted on the top left side of the base plate 1. Multiple mounting frames 4 are evenly spaced and rotatably connected to the conveyor chain 202 of the suspended conveyor 2. For ease of illustration, only one mounting frame 4 is shown in the figure. A lifting frame 5 is slidably connected to the mounting frame 4. Four circular holes are symmetrically opened at the bottom of the lifting frame 5. A lifting cylinder 6 is connected to the bottom of the lifting frame 5. The top of the lifting cylinder 6 is open, and the interior of the lifting cylinder 6 is connected to the outside through the circular holes at the bottom of the lifting frame 5. The inner side of the lifting cylinder 6 is slidably connected to a sliding sleeve 7, and the top of the sliding sleeve 7 is symmetrically opened with four through holes 701. The outer side of the sliding sleeve 7 is wound with a first spring 8, and the two ends of the first spring 8 are respectively connected to the bottom of the lifting cylinder 6 and the lower part of the sliding sleeve 7. The bottom of the sliding sleeve 7 is circumferentially connected with four positioning pieces 9. The lower part of the inner wall of the sliding sleeve 7 is connected to an airbag 10, which is conical in shape. The mounting frame 4 is provided with a lifting assembly for driving the lifting frame 5 to lift. The conveyor chain 202 is provided with a power supply assembly for supplying power to the lifting assembly. The lifting frame 5 is provided with a control assembly for controlling the expansion or contraction of the airbag 10. The guide rail 201 of the suspended conveyor 2 is provided with an adjustment assembly for adjusting the tension of the conveyor chain 202.

[0027] like Figure 2 As shown, the lifting assembly includes a drive motor 1101 and a lead screw 1102. The drive motor 1101 is mounted on the upper part of the mounting frame 4, and the lead screw 1102 is rotatably connected to the upper part of the mounting frame 4. The top of the lead screw 1102 is connected to the output shaft of the drive motor 1101, and the upper part of the lifting frame 5 is threadedly connected to the lead screw 1102.

[0028] like Figure 2 and Figure 3 As shown, the power supply assembly includes a pantograph 1201 and a conductive copper plate 1202. Multiple pantographs 1201 are evenly spaced on the top of the conveyor chain 202. Each pantograph 1201 corresponds to a mounting frame 4, and the pantograph 1201 is electrically connected to the drive motor 1101. A conductive copper plate 1202 is installed on the inner top front side of the guide rail 201. The conductive copper plate 1202 is used for external power supply. When the conductive copper plate 1202 contacts the pantograph 1201, the conductive copper plate 1202 and the pantograph 1201 cooperate to supply power to the drive motor 1101.

[0029] like Figure 4 As shown, the control assembly includes a vertical rod 13 and a piston plate 14. The bottom of the lifting frame 5 is connected to the vertical rod 13, which passes through the middle of the top of the sliding sleeve 7. The bottom of the vertical rod 13 is connected to the top of the airbag 10. The middle of the vertical rod 13 is connected to the piston plate 14, which is in contact with and sealed to the inner wall of the sliding sleeve 7.

[0030] like Figure 1 and Figure 5 As shown, the adjustment assembly includes a sliding frame 15, an electric push rod 16, and a detection mechanism. The right side of the guide rail 201 is slidably connected to the sliding frame 15 and remains connected. The conveyor chain 202 slides through the interior of the sliding frame 15. The electric push rod 16 is installed on the top right side of the guide rail 201, and the top of the sliding frame 15 is connected to the telescopic rod of the electric push rod 16. The interior of the sliding frame 15 is provided with a detection mechanism for detecting the tension of the conveyor chain 202. The detection mechanism includes a slider 17, a rotating wheel 18, a pressure sensor 19, and a second spring 20. The slider 17 is slidably connected to the upper interior of the sliding frame 15. The rotating wheel 18 is rotatably connected to the slider 17, and the rotating wheel 18 is in contact with the right side of the conveyor chain 202. The pressure sensor 19 is installed on the right side of the slider 17, and the second spring 20 is connected between the right side of the pressure sensor 19 and the inner wall of the sliding frame 15.

[0031] When the equipment is needed, it is first installed in the designated location, positioned behind the plastic bottle supply station. Then, the controller 3 controls the overhead conveyor 2 to start working, driving the conveyor chain 202 to move along the guide rail 201. The conveyor chain 202 drives the mounting frame 4 and the pantograph 1201 to move synchronously. The plastic bottles are then conveyed to the area directly below the conductive copper plate 1202 via the feeding conveyor. When the pantograph 1201 moves to contact the conductive copper plate 1202, the contact between the conductive copper plate 1202 and the pantograph 1201 provides power to the drive motor 1101. When directly below, controller 3 will stop the conveyor chain 202 and control drive motor 1101 to drive lead screw 1102 to rotate. Lead screw 1102 drives lifting frame 5 to move downward. Lifting frame 5 drives lifting cylinder 6, sliding sleeve 7, positioning plate 9, airbag 10, vertical rod 13 and piston plate 14 to move downward. When positioning plate 9 contacts the plastic bottle, positioning plate 9 can press down on the plastic bottle to fix it. At the same time, positioning plate 9 and sliding sleeve 7 will stop moving downward due to obstruction, while lifting frame 5, lifting cylinder 6, vertical rod 13 and piston plate 14 will continue to move downward. The first spring 8 is compressed, and vertical rod 13 will drive the top of airbag 10 to move downward, causing the airbag to... The piston plate 14 extends into the plastic bottle, and the piston plate 14 compresses the air inside the sliding sleeve 7. The air inside the sliding sleeve 7 can enter the airbag 10, causing the airbag 10 to inflate. The airbag 10 will then adhere to the inner wall of the plastic bottle. Then, the controller 3 will control the conveyor chain 202 to continue moving. The conveyor chain 202 will drive the pantograph 1201 to move until it disengages from the conductive copper plate 1202. The conveyor chain 202 can also drive the plastic bottle to move through the airbag 10. This process is repeated to complete the conveying of the plastic bottle. When the pantograph 1201 moves to contact the next conductive copper plate 1202, the controller 3 will control the conveyor chain 202 to stop moving and control the drive motor 1 When the lead screw 1102 reverses, it drives the lifting frame 5 to move upward and reset. The lifting frame 5 drives the lifting cylinder 6, the vertical rod 13, and the piston plate 14 to move upward and reset. The first spring 8 gradually returns to its original state. The piston plate 14 draws the air inside the airbag 10 back into the sliding sleeve 7, so that the airbag 10 contracts and returns to its original state and separates from the inner wall of the plastic bottle, thus placing the plastic bottle in the designated position. At the same time, the vertical rod 13 drives the top of the airbag 10 to move upward and reset, retracting the airbag 10 into the sliding sleeve 7. When the first spring 8 has completely returned to its original state, the lifting cylinder 6 drives the sliding sleeve 7 and the positioning plate 9 to move upward and reset, so that the positioning plate 9 separates from the plastic bottle.During the conveying process, the roller 18 pressed against the side of the conveyor chain 202 rotates under the friction of the conveyor chain 202. The conveyor chain 202 generates a leftward frictional force on the roller 18. According to Newton's third law, the roller 18 experiences an equal and rightward reaction force. This force pushes the slider 17, roller 18, and pressure sensor 19 to compress the second spring 20. The compression of the second spring 20 (i.e., the elastic force) is proportional to the tension of the conveyor chain 202. The pressure sensor 19 can indirectly and accurately monitor the tension of the conveyor chain 202 by detecting this elastic force in real time. When the pressure sensor 19 detects that the tension of the conveyor chain 202 is less than the minimum value of the preset range, the pressure sensor 19 will send a signal. After receiving the signal, the controller 3 will control the electric push rod 16 to drive the sliding frame 15 to move to the right, thereby shortening the overlap length between the sliding frame 15 and the guide rail 201 to tighten the conveyor chain 202, thus increasing the conveyor chain's tension. The tension of conveyor chain 202 is controlled by the following mechanism: When pressure sensor 19 detects that the tension of conveyor chain 202 is greater than the minimum value of the preset range, pressure sensor 19 sends a signal. Upon receiving the signal, controller 3 controls electric push rod 16 to stop working. Similarly, when pressure sensor 19 detects that the tension of conveyor chain 202 is greater than the maximum value of the preset range, pressure sensor 19 also sends a signal. Upon receiving the signal, controller 3 controls electric push rod 16 to drive sliding frame 15 to move to the left, thereby increasing the overlap length between sliding frame 15 and guide rail 201, thus relaxing conveyor chain 202 and reducing its tension. When pressure sensor 19 detects that the tension of conveyor chain 202 is less than the maximum value of the preset range, pressure sensor 19 sends a signal. Upon receiving the signal, controller 3 controls electric push rod 16 to stop working. This allows for dynamic adjustment of the tension of conveyor chain 202 to maintain it within a suitable range.

[0032] like Figure 6 and Figure 7 As shown, it also includes a positioning assembly, which includes a fixed plate 21, a swing frame 22, rollers 23, a third spring 24, and short rods 25. Fixed plates 21 are connected to the lower parts of the left and right sides of the mounting frame 4. Vertical holes are symmetrically opened on both fixed plates 21. Swing frames 22 are symmetrically connected between the lower parts of the two fixed plates 21. Two rollers 23 are rotatably connected to the lower parts of the two swing frames 22 on opposite sides. Third springs 24 are symmetrically connected between the upper parts of the two swing frames 22. Two short rods 25 are connected to the lower parts of the left and right sides of the lifting frame 5. The short rods 25 pass through the vertical holes and are in contact with the swing frames 22.

[0033] In the initial state, such as Figure 6As shown, the swing frame 22 is in the open state, and the third spring 24 is in the stretched state. When the conveyor chain 202 moves the mounting frame 4 and the pantograph 1201, the mounting frame 4 will move the entire positioning assembly synchronously. When the pantograph 1201 moves directly below the conductive copper plate 1202, the swing frames 22 on the front and rear sides will be positioned on the front and rear sides of the plastic bottle, respectively. When the lifting frame 5 moves downward, the lifting frame 5 will move the short rod 25 downward, causing the short rod 25 to disengage from the swing frame 22. At this time, the third spring 24 will return to its original state, causing the swing frames 22 on the front and rear sides to swing to opposite sides. The swing frame 22 will drive the rollers 23 on the front and rear sides to swing to the opposite side. When the rollers 23 come into contact with the plastic bottle, they can push the plastic bottle to move and center, ensuring that the subsequent vertical rod 13 can accurately insert the airbag 10 into the plastic bottle. When the lifting frame 5 moves upward to reset, the lifting frame 5 will drive the short rod 25 to move upward to reset. When the short rod 25 comes into contact with the swing frame 22, the short rod 25 will squeeze the swing frame 22 on the front and rear sides to swing to the opposite side to reset. The third spring 24 is stretched, and the swing frame 22 will drive the rollers 23 on the front and rear sides to swing to the opposite side to reset, so that the rollers 23 are separated from the plastic bottle.

[0034] like Figure 8 As shown, it also includes a fixing block 26 and a stop bar 27. The top of the mounting frame 4 is symmetrically connected with the fixing blocks 26 on the left and right sides, and the conveyor chain 202 is symmetrically connected with the stop bars 27. The stop bars 27 correspond one-to-one with the fixing blocks 26. When the stop bars 27 contact the fixing blocks 26, they can limit the mounting frame 4.

[0035] When the guide rail 201 has a rising or falling section, the conveyor chain 202 will tilt when it moves to that section, thereby causing the plastic bottles to rise or fall. The stop bar 27 will rotate with the tilt of the conveyor chain 202. Since the mounting frame 4 is rotatably connected to the conveyor chain 202, the mounting frame 4 will not rotate synchronously with the conveyor chain 202. When the tilt angle of the conveyor chain 202 is small, the stop bar 27 will not contact the fixed block 26, and the mounting frame 4 will always remain vertical. When the tilt angle of the conveyor chain 202 is large, the stop bar 27 will contact the fixed block 26 and squeeze the fixed block 26 to rotate. The fixed block 26 will drive the mounting frame 4 to rotate, thereby preventing the included angle between the mounting frame 4 and the conveyor chain 202 from being too small, thus preventing two adjacent plastic bottles from colliding.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
