Description

Technical Field

[0001] The present invention relates to the technical field of production and transportation, and specifically relates to a conveying device for plastic packaging containers used in food production. Background Art

[0002] During food processing and production, plastic bottles are required for use. When conveying plastic bottles, they are mostly horizontally conveyed through a horizontal conveyor belt. During the conveying process, in order to keep a certain distance between plastic bottles, this behavior is mainly operated through a spiral bottle separating mechanism;

[0003] The invention with the existing publication number CN103587933B discloses a double - spiral bottle separating device. The floating plate is used to push the bottles in, and the complementary cooperation of the positive and negative spirals smoothly separates the bottles arranged together and increases the distance between the bottles to facilitate conveying and protect the bottle body from damage. Since the plastic bottles are relatively light in themselves, they are prone to tipping during the movement without contacting the screw rod. Based on this problem, in the existing solution, negative pressure pumping is set below the conveyor belt, and then suction holes are set on the conveyor belt. When the plastic bottle is at the position of the suction holes on the conveyor belt, under the action of negative pressure, the vertical posture of the plastic bottle is maintained to ensure that the feeding bottle will not tip over if the speed changes during the conveying process. However, this method of negative pressure suction below will accumulate pollutants in the external air in the suction groove and on the surface of the conveyor belt, and it is not easy to carry out maintenance treatment after long - term use.

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to the attached Figures 1 - 15 , and the following technical solutions are provided in this application.

[0038] Embodiment 1: A conveying device for plastic packaging containers used in food production, comprising:

[0039] Conveyor table 1, a cleaning treatment groove 3 is opened on one side of the upper end of the conveyor table 1, negative pressure suction grooves 4 are opened on the upper ends of both sides of the conveyor table 1 where the cleaning treatment groove 3 is located, a conveyor belt 2 is movably arranged above the conveyor table 1, one side of the conveyor belt 2 is inserted into the cleaning treatment groove 3, a roller support 40 is arranged on one side of the conveyor table 1 close to the cleaning treatment groove 3, a spiral spacer roller 41 is rotatably arranged on one side of the roller support 40, first support grooves and second support grooves are sequentially opened on both sides of the conveyor table 1 where the negative pressure suction groove 4 is located, support conveyor strips 6 are arranged in the first support grooves through rotating wheels, a plurality of conveying support rollers 5 are horizontally arranged in the second support grooves, the lower end of the conveyor belt 2 is lapped on the support conveyor strips 6 and the conveying support rollers 5, and a plurality of adsorption holes are opened in the middle of the conveyor belt 2 where the negative pressure suction groove 4 is located. When the plastic bottle moves normally on the conveyor belt 2, negative pressure air is generated through the negative pressure suction groove 4 to cause negative pressure adsorption force on the adsorption holes. At this time, the plastic bottle is adsorbed and adhered to the conveyor belt 2. The conveyor belt 2 moves smoothly through the negative pressure suction groove 4 and the support conveyor strips 6. The support conveyor strips 6 can perform a certain degree of sealing treatment on both sides of the negative pressure suction groove 4 when the conveyor belt 2 is in contact. In addition, the number or coverage area of the adsorption holes can be customized according to requirements, as long as it is within the range of the negative pressure suction groove 4.

[0040] A surface treatment component is arranged to clean the surface of the conveyor belt 2. The surface treatment component is arranged on one side of the conveyor table 1 through a control component. The surface treatment component includes a functional shaft 8, and one side of the functional shaft 8 is inserted into the cleaning treatment groove 3. The control component includes a push piston 13 and an intermediate transmission control cylinder 17. A first support cylinder 7 is arranged on one side of the conveyor table 1 close to the cleaning treatment groove 3. The push piston 13 and the intermediate transmission control cylinder 17 are both movably arranged in the first support cylinder 7. A cleaning cylinder 20 is sleeved on one side of the functional shaft 8 inserted into the cleaning treatment groove 3. The upper surface of the conveyor belt 2 inserted into the cleaning treatment groove 3 is in contact with the lower end of the cleaning cylinder 20. A second support cylinder 9 is arranged on one side of the conveyor table 1 located in the first support cylinder 7. A ball ring is arranged on one side in the second support cylinder 9. The functional shaft 8 movably penetrates through the ball ring, and a plurality of support balls 10 are movably inserted on one side of the ball ring close to the functional shaft 8. When the conveyor belt 2 passes through the cleaning treatment groove 3, it needs to contact the cleaning cylinder 20 of the functional shaft 8. At this time, when the rotation direction of the functional shaft 8 is opposite to the moving direction of the conveyor belt 2, the conveyor belt 2 can be scraped and cleaned.

[0041] On one side of the first support cylinder 7 away from the conveying platform 1, a pushing piston groove 11 is opened. A pushing piston 13 is movably inserted in the pushing piston groove 11. A rhombic guide block 12 is provided at the center of one side of the pushing piston 13. The rhombic guide block 12 movably penetrates through the pushing piston groove 11. A return spring 14 is sleeved on one side of the rhombic guide block 12 located in the pushing piston groove 11. A support shaft block 15 is provided at the center of the side where the rhombic guide block 12 penetrates through the pushing piston groove 11. On the side of the functional shaft 8 away from the conveying platform 1, a bearing sleeve 16 is provided. The bearing sleeve 16 is sleeved on the support shaft block 15 through a bearing. On the side of the functional shaft 8 close to the bearing sleeve 16, a second clutch disc 19 is provided. Inside the first support cylinder 7, close to the second clutch disc 19, a middle transmission control cylinder 17 is rotatably provided through a bearing. The middle transmission control cylinder 17 is sleeved on the functional shaft 8. The inner diameter of the middle transmission control cylinder 17 is larger than the diameter of the functional shaft 8. At one end of the middle transmission control cylinder 17 close to the second clutch disc 19, a first clutch disc 18 is provided. When the pushing piston 13 presses the return spring 14, the second clutch disc 19 contacts the first clutch disc 18. Anti-slip teeth are provided on the sides of the second clutch disc 19 and the first clutch disc 18 that contact each other. The functional shaft 8 is horizontally arranged through the support of the ball ring and the support shaft block 15, so that one end of the functional shaft 8 can be stably inserted into the cleaning treatment tank 3. When the air inlet at one end of the pushing piston groove 11 is connected to high-pressure gas, the high-pressure gas pushes the pushing piston 13 and the rhombic guide block 12 to move towards the position of the functional shaft 8. Since the rhombic guide block 12 is rotatably connected to the functional shaft 8 through a bearing, at this time the functional shaft 8 is pushed to move. The second clutch disc 19 of the functional shaft 8 abuts against and contacts the first clutch disc 18. Then when the middle transmission control cylinder 17 and the first clutch disc 18 rotate, the rotation of the functional shaft 8 can be controlled to realize the scraping and cleaning of the surface of the cleaning cylinder 20 and the conveyor belt 2. The pushing piston 13 can only move horizontally under the action of the rhombic guide block 12 and will not rotate, thus avoiding unnecessary losses. The moving distance between the second clutch disc 19 and the first clutch disc 18 is relatively small, ensuring that when the functional shaft 8 does not need to be actively controlled to rotate, the second clutch disc 19 and the first clutch disc 18 can be separated. In this way, when the functional shaft 8 is horizontally pushed, the influence of the cleaning cylinder 20 on the deformation of the conveyor belt 2 is relatively small.

[0042] A second worm gear 42 is provided at one end of the central transmission control cylinder 17 away from the first clutch disk 18, and a second worm 43 is horizontally rotatably plugged into the lower end of the first support cylinder 7 located on one side of the second worm gear 42. A driving box is provided on one side of the roller bracket 40, and the output shaft of the driving box passes through the roller bracket 40 and is provided with a synchronous control shaft 44. The synchronous control shaft 44 is respectively connected to the spiral spacing roller 41 and one side of the second worm 43 through a pulley and a belt. When the output shaft of the driving box controls the synchronous control shaft 44 to rotate, the synchronous control shaft 44 controls the spiral spacing roller 41 and the second worm 43 to rotate through the belt. When the spiral spacing roller 41 rotates, the plastic bottles are spaced above the conveyor belt 2 through its own spiral structure. The rotation of the second worm 43 can control the rotation of the second worm gear 42, the central transmission control cylinder 17 and the first clutch disk 18, thereby realizing the rotation control of the functional shaft 8.

[0043] Embodiment 2: On the basis of embodiment 1, a negative pressure treatment component is set to treat the negative pressure air sucked in the negative pressure suction groove 4. The negative pressure treatment component is arranged in the negative pressure suction groove 4. The negative pressure treatment component includes a negative pressure filter cartridge 30 and a suction air window 28. A fixed support plate 27 is fixedly arranged at one end of the negative pressure suction groove 4 away from the cleaning treatment groove 3. One end of the negative pressure filter cartridge 30 is rotatably sleeved with the fixed support plate 27. The end of the negative pressure filter cartridge 30 away from the fixed support plate 27 is fixedly plugged with a self-rotating mounting plate 31. The fixed support plate 27 is located at the center of one side of the negative pressure filter cartridge 30 and is horizontally provided with a partition support plate 29. The filter cartridge 30 is rotatably sleeved on the partition support plate 29, and the two side surfaces of the partition support plate 29 are in contact with the inner wall of the negative pressure filter cartridge 30. The upper end of the fixed support plate 27 located in the negative pressure filter cartridge 30 is provided with a suction window 28. When the suction window 28 is squeezed into the suction fan generated by the negative pressure, the suction window 28 generates a negative pressure suction force on the space above the partition support plate 29 in the negative pressure filter cartridge 30, and then generates a negative pressure suction force on the space above the negative pressure suction groove 4. The degree to which the negative pressure in the lower part of the negative pressure filter cartridge 30 is affected by the negative pressure is greatly weakened due to the contact between the partition support plate 29, the negative pressure filter cartridge 30 and the side of the negative pressure suction groove 4.

[0044] A first gear groove is formed on one side of the functional shaft 8 in the cleaning treatment tank 3. One end of the functional shaft 8 is inserted into the first gear groove and is provided with a control gear 22. A feeding air groove 21 is formed through the center of the functional shaft 8, passing through the pushing piston 13 and the control gear 22. A one-way valve 23 is provided on one side of the feeding air groove 21 inside the control gear 22. A connecting air groove 24 is formed in the conveying platform 1 on one side of the first gear groove, communicating with the feeding air groove 21. A transmission groove is formed in the conveying platform 1 on one side of the cleaning treatment tank 3. A support connecting shaft is provided at the center of one side of the self-rotating mounting disc 31. The support connecting shaft is inserted into the transmission groove through a bearing and is provided with a first worm gear 32. Second gear grooves are formed in the conveying platform 1 on both sides of the first gear groove, and first worms 35 are horizontally inserted between the second gear grooves and the transmission groove. One side of the first worm 35 is meshed and connected with the first worm gear 32. A driven gear 36 is provided on one side of the first worm 35 inside the second gear groove. One side of the driven gear 36 is meshed and connected with one side of the control gear 22, and the tooth length of the control gear 22 is greater than the tooth length of the driven gear 36. When the second clutch disc 19 is attached to the first clutch disc 18, the rotation of the intermediate transmission control cylinder 17 can not only drive the functional shaft 8 and the cleaning cylinder 20 to rotate, but also realize the rotation of the driven gear 36, the first worm 35, the first worm gear 32 and the negative pressure filter cylinder 30. At this time, the partition support plate 29 remains stationary. The rotation of the negative pressure filter cylinder 30 can rotate the area of the negative pressure filter cylinder 30 originally above the partition support plate 29 to below the partition support plate 29, so that the negative pressure filter cylinder 30 blocked by air pollutants above is moved to below.

[0045] First transfer air grooves 25 are formed on both sides inside the connecting air groove 24. A rhombus connecting groove 33 is formed at the center of one side inside the transmission groove. A rhombus connecting pipe is horizontally provided at one end of the partition support plate 29 close to the first worm gear 32. The rhombus connecting pipe movably passes through the center of the support connecting shaft and the first worm gear 32 and is inserted into the rhombus connecting groove 33. A cleaning air blowing groove 37 is formed in the partition support plate 29 through the rhombus connecting pipe. Second transfer air grooves 34 are formed between one side of the rhombus connecting groove 33 and the first transfer air groove 25. A dust and dirt collection groove 39 is formed at the lower end of the conveying platform 1 in the negative pressure suction groove 4. The width of the dust and dirt collection groove 39 is smaller than the width of the partition support plate 29. A plurality of conical cleaning holes 38 are formed at the lower end of the cleaning air blowing groove 37 through the partition support plate 29. The one-way ventilation release pressure of the one-way valve 23 is greater than the elastic support force of the return spring 14. After the functional shaft 8 is horizontally pushed towards the position of the connecting air groove 24, the high-pressure gas in the pushing piston groove 11 will enter the connecting air groove 24, the first transfer air groove 25 and the second transfer air groove 34 from the position of the one-way valve 23. Then, the high-pressure gas blows towards the lower part of the negative pressure filter cylinder 30 close to the dust and dirt collection groove 39 from the rhombus connecting groove 33, the cleaning air blowing groove 37 and the plurality of conical cleaning holes 38 to perform reverse cleaning on the pollutants attached to the holes of the negative pressure filter cylinder 30.
