[0001] The present invention relates to the technical field of conveying equipment, and particularly to a processing and conveying equipment for food plastic packaging containers. Background Art

[0002] Food packaging is an important part of turning food into a commodity and is also a link in the food industry process. Food plastic packaging containers refer to containers made by molding plastic raw materials for packaging food. Due to characteristics such as light weight, easy processing, good packaging effect, and corrosion resistance, they have currently replaced packaging containers made of materials such as metal, glass, ceramics, and wood in many aspects and have been widely used in the field of food packaging.

The dust cleaning device includes a rotating shaft, cleaning brushes arranged on the outer peripheral surface of the rotating shaft, and a second motor for driving the rotating shaft to rotate. The spraying and coding device includes an ink box for storing ink and a spray gun connected to the ink box.

Detailed implementation mode

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 making creative efforts belong to the scope of protection of the present invention.

[0035] Please refer to Figures 1 - 7 As shown, the present application provides a processing and conveying device for a food plastic packaging container, including a conveying table 1 and a workpiece body 6, and further including:

[0036] A lifting mechanism 2, arranged on the conveying table 1, for driving the lifting and rotation of the workpiece body 6;

[0037] A conveying mechanism 5, connected to the conveying table 1, for conveying the workpiece body 6 to the lifting mechanism 2;

[0038] A sliding-down mechanism 3, arranged above the conveying table 1, for the sliding-down of the workpiece body 6;

[0039] A clamping mechanism 7, connected to the lifting mechanism 2, for clamping the workpiece body 6;

[0040] Two groups of inkjet printing bins 4 are arranged on both sides of the lifting mechanism 2 respectively, for the inkjet printing work of the workpiece body 6;

[0041] During operation, in the prior art, the dust on the packaging box is cleaned by a dust cleaning device, and then the inkjet printing work is carried out. However, it is found in the actual working process that the inkjet printing on the packaging box is different in different fields. Some packaging boxes need to be inkjet printed with inkjet codes other than the production date, such as 3C logos, etc. Most of the packaging boxes are tetrahedrons. When spraying, the packaging box needs to be rotated to avoid covering during spraying. However, this device is not equipped with a mechanism for flipping the packaging box, resulting in the need for manual operation during spraying, so that this device cannot realize the production of packaging boxes in other fields, resulting in low adaptability. In order to prevent such events from occurring, first, the workpiece body 6 is placed on the conveying mechanism 5 of the conveying table 1, and then the conveying mechanism 5 is used to convey the workpiece body 6 into the inkjet printing bin 4 for inkjet printing. After the inkjet printing is completed, the conveying mechanism 5 is used to convey the workpiece body 6 below the lifting mechanism 2, and the clamping mechanism 7 in the lifting mechanism 2 is used to clamp the workpiece body 6. After clamping, the lifting mechanism 2 drives the clamping mechanism 7 to rise, and the workpiece body 6 is rotated and turned over during the rising process. Then the clamping mechanism 7 releases the workpiece body 6, and the workpiece body 6 is slid down to the conveying table 1 by the sliding-down mechanism 3, and finally the inkjet printing work is carried out.

[0042] Such asAs shown in Figures 3 - 6 , the conveying mechanism 5 includes a conveyor belt 51; the conveyor belt 51 is rotatably arranged in the conveying table 1; the lifting mechanism 2 includes a lifting bin 21; there are two groups of the lifting bins 21; a lifting screw rod 25 is rotatably connected in the lifting bin 21; a lifting block 24 is threadedly connected to the lifting screw rod 25; the clamping mechanism 7 includes a rotating column 74; the rotating column 74 is rotatably connected to the side wall of the lifting block 24; a connecting column 75 is arranged at one end of the rotating column 74 away from the lifting block 24; a clamping box 71 is rotatably connected to one end of the connecting column 75 away from the rotating column 74; a clamping screw rod 72 is rotatably connected in the clamping box 71; a clamping block 73 is threadedly connected to the clamping screw rod 72; a telescopic column 76 is fixedly connected to the side wall of the clamping block 73; a telescopic spring 761 is fixedly connected in the telescopic column 76; one end of the telescopic spring 761 away from the telescopic column 76 is fixedly connected to a clamping column 77; the clamping column 77 is slidably arranged in the telescopic column 76; a clamping plate 78 is fixedly connected to one end of the clamping column 77 away from the telescopic spring 761; a rotating gear 741 is fixedly connected to the rotating column 74; a connecting gear 751 is fixedly connected to the connecting column 75; the input end of the clamping screw rod 72 is fixedly connected to the output end of the connecting column 75; a lifting tooth groove 29 is fixedly connected to the side wall of the lifting bin 21; the rotating gear 741 and the connecting gear 751 are meshed with the lifting tooth groove 29; an upper notch 291 and a lower notch 292 are formed in the lifting tooth groove 29; an axis 752 is arranged in the connecting column 75; both ends of the axis 752 are fixedly connected to the rotating column 74 and the connecting column 75 respectively;

[0043] ​During operation, the workpiece body 6 is placed on the conveying table 1 in the conveying table 1. Subsequently, the conveyor belt 51 conveys the workpiece body 6 below the lifting bin 21. During the conveying process, the lifting screw rods 25 in the left and right groups of lifting bins 21 rotate. When rotating, they drive the lifting blocks 24 to descend. The initial position of the lifting block 24 is at the lower one-third of the bottom of the lifting bin 21. While the lifting block 24 descends, it drives the clamping box 71 to descend. While the clamping box 71 descends, the connecting gear 751 is driven to rotate by the lifting tooth groove 29 on the side. When the connecting gear 751 rotates, it drives the clamping screw rod 72 in the clamping box 71 to rotate, thereby driving the clamping block 73 on the clamping screw rod 72 to move towards the workpiece body 6. During the moving process, the workpiece body 6 is clamped through components such as the telescopic column 76 and the clamping plate 78. And a telescopic spring 761 is arranged in the telescopic column 76. When the clamping plate 78 contacts the workpiece body 6, the clamping screw rod 72 continues to rotate to drive the clamping plate 78 to move towards the workpiece body 6, thereby squeezing the telescopic spring 761. When the clamping column 77 is completely retracted into the telescopic column 76, the lifting block 24 will reach the bottom of the lifting bin 21. At the same time, the lifting screw rod 25 continues to rotate. When rotating, the lifting block 24 will rotate and rise. During the rising process, it will drive the workpiece body 6 to rise together. When rising, the connecting gear 751 will also be driven to rotate by the lifting tooth groove 29. When the connecting gear 751 reaches the initial position and then moves upward, it will reach the upper notch 291 of the lifting tooth groove 29, thereby losing the driving force and interrupting the rotation of the connecting gear 751 and the clamping screw rod 72. At the same time, the rotating gear 741 meshes with the lifting tooth groove 29. After meshing, it will drive the clamping box 71 and the whole workpiece to rotate 180° by means of the rotating column 74. While flipping, the lifting screw rod 25 continues to rotate, driving the lifting block 24 to rise. When the clamping box 71 and the workpiece body 6 are flipped to 120°, the connecting gear 751 meshes and connects with the lifting tooth groove 29 again. At this time, the clamping screw rod 72 is driven to rotate again, causing the clamping plate 78 to move towards the clamping box 71, slowly releasing the clamping of the workpiece body 6. When the 180° rotation is completed, the workpiece body 6 loses the clamping, thereby realizing the flipping of the workpiece body 6 and falling onto the conveying table 1 through the sliding and descending mechanism 3 for the next inkjet coding work. It should be noted that there are an upper notch 291 and a lower notch 292 opened on the lifting tooth groove 29. The lower notch 292 is arranged at the position of the rotating gear 741, that is, when the lifting block 24 drives the clamping box 71 to descend, it will not be able to drive the clamping box 71 to rotate by means of the rotating gear 741. The upper notch 291 is arranged at the position of the connecting gear 751, that is, when rising, the clamping of the workpiece body 6 cannot be continuously released. At the same time, when rising from the bottom of the lifting bin 21, since the lifting tooth groove 29 is still meshed with the connecting gear 751 at this section, according to the setting of the telescopic spring 761, the workpiece body 6 can be continuously clamped by the telescopic spring 761 when the clamping plate 78 moves back. When the connecting gear 751 is disengaged from the lifting tooth groove 29,The clamping of the workpiece body 6 is achieved by the rebound of the telescopic spring 761. When the connecting gear 751 at the top of the lifting bin 21 is re-engaged, the clamping plate 78 is driven to move back again, completely releasing the workpiece body 6. Through the setting of the clamping mechanism 7, the workpiece body 6 can be clamped by the clamping plate 78 while the conveyor table 1 conveys the workpiece body 6. And through the setting of the lifting bin 21, after clamping, the workpiece body 6 can be driven to rise, and at the same time, the workpiece body 6 is driven to flip, realizing the inkjet coding on the other side of the workpiece body 6. After flipping, the workpiece body 6 is put down, and at the same time, the components in the lifting bin 21 return to the initial position, waiting for the next flipping work of the workpiece body 6, realizing the multi-faceted spraying of the workpiece body 6.

[0044] As Figure 2 shown, a connecting tooth 52 is fixedly connected to the conveyor belt 51; multiple groups of the connecting teeth 52 are provided; a driven gear 23 is rotatably connected to the conveyor table 1; the driven gear 23 is meshed and connected with the connecting tooth 52; a driving gear 22 is rotatably connected to the bottom of the lifting bin 21; the driving gear 22 is meshed and connected with the driven gear 23; the input end of the lifting screw 25 is fixedly connected to the output end of the driving gear 22;

[0045] During operation, after the workpiece body 6 is placed on the conveyor belt 51, the conveyor belt 51 is driven to move. During the movement, the workpiece body 6 is conveyed to the lifting bin 21. At the same time, the connecting tooth 52 and the driven gear 23 are used to drive the driving gear 22 to rotate, and then drive the lifting gear in the lifting bin 21 to rotate. And while the lifting mechanism 2 and the clamping mechanism 7 are working, the conveyor belt 51 continues to move. When the workpiece body 6 falls off through the sliding and descending mechanism 3 after flipping, the clamping box 71 in the lifting bin 21 returns to the initial position, waiting for the next flipping work.

[0046] As Figure 3As shown in the figure, the sliding and descending mechanism 3 includes a lower slide plate 31 and an upper slide plate 33; the lower slide plate 31 is fixedly connected to the conveying table 1; a moving bin 26 is fixedly connected to the side wall of the lifting bin 21; a moving lead screw 27 is rotatably connected in the moving bin 26; a moving block 28 is threadedly connected to the moving lead screw 27; the side wall of the moving block 28 is fixedly connected to the upper slide plate 33; a connecting rod 263 is rotatably connected to the top of the moving bin 26; a first gear 261 and a second gear 262 are respectively fixedly connected to both ends of the connecting rod 263; a moving gear 271 is rotatably connected to the side wall of the moving bin 26; the output end of the moving gear 271 is fixedly connected to the input end of the moving lead screw 27; the first gear 261 is meshed and connected to the moving gear 271; a driving gear 211 is rotatably connected to the top of the lifting bin 21; the output end of the lifting lead screw 25 is fixedly connected to the input end of the driving gear 211; a driving belt 212 is sleeved on the driving gear 211; the other end of the driving belt 212 is sleeved on the second gear 262; pulleys 32 are arranged in the upper slide plate 33 and the lower slide plate 31.

[0047] During operation, when the lifting lead screw 25 rotates, it will drive the driving gear 211 to rotate. According to the driving gear 211 and the driving belt 212, the second gear 262 will be driven to rotate. Then, the first gear 261 will be driven to rotate through the transmission rod, and the moving lead screw 27 in the moving bin 26 will be driven to rotate through the moving gear 271. Thus, the reciprocating movement of the upper slide plate 33 is realized by using the moving block 28. When the clamping box 71 is in the initial position, it is below the lower slide plate 31. When it rises and its height exceeds the lower slide plate 31 and the upper slide plate 33, the upper slide plate 33 will be driven to come below the workpiece body 6. Subsequently, the clamping plate 78 releases the workpiece body 6, and the workpiece body 6 falls parallel to the upper slide plate 33. It slides to the lower slide plate 31 through the sliding of the pulley 32 and then reaches the conveyor belt 51. During operation, the upper slide plate 33 continuously makes reciprocating movements. However, when the height of the workpiece body 6 is higher than the upper slide plate 33, the upper slide plate 33 will simultaneously reach below the workpiece body 6 to support the workpiece body 6 and prevent the workpiece body 6 from falling onto the conveyor belt 51 when released, resulting in a change in angle.

[0048] As Figure 2 shown in the figure, a base 61 is fixedly connected to the conveyor belt 51; the workpiece body 6 is placed on the base 61.

[0049] During operation, the workpiece body 6 can be fixed through the base 61. The base 61 drags the workpiece body 6 to the lifting bin 21. After the workpiece body 6 is clamped, the base 61 is continuously driven by the conveyor belt 51 to move. When the base 61 passes through the lower slide plate 31, the workpiece body 6 is turned over and simultaneously slides onto the base 61 for the next inkjet coding work.

[0050] As Figure 2As shown, a main motor 11 is fixedly connected to the side wall of the conveying table 1; the conveyor belt 51 is driven by the main motor 11;

[0051] During operation, the conveyor belt 51 is driven by the main motor 11 to work, so as to realize the work of the lifting mechanism 2, the clamping mechanism 7 and the upper slide plate 33.

[0052] As Figure 3 shown, the upper slide plate 33 is shorter than the lower slide plate 31 and is arranged with the same inclination angle;

[0053] During operation, the same angle setting can avoid the phenomenon that the workpiece body 6 topples over when sliding.

[0054] As Figure 4 shown, the clamping plate 78 is made of rubber material;

[0055] During operation, the rubber clamping plate 78 can achieve an anti-slip effect and prevent the workpiece body 6 from slipping.

[0056] Working principle of the present invention: In the prior art, the dust on the packaging box is cleaned by a dust cleaning device, and then the inkjet coding work is carried out. However, it is found in the actual working process that according to different fields, the inkjet coding on the packaging box is also different. Some packaging boxes need to be sprayed with inkjet coding other than the production date on the surface, such as 3C logos, etc. And most of the packaging boxes are tetrahedrons. When spraying, the packaging box needs to be rotated to avoid covering during spraying. And this device is not equipped with a mechanism for flipping the packaging box, resulting in the need for manual operation during spraying, which causes this device to be unable to realize the production of packaging boxes in other fields and has low adaptability. In order to prevent such events from occurring, first, the workpiece body 6 is placed on the conveying mechanism 5 of the conveying table 1, and then the workpiece body 6 is conveyed to the inkjet coding bin 4 by the conveying mechanism 5 for inkjet coding. After the inkjet coding is completed, the workpiece body 6 is conveyed to the lower part of the lifting mechanism 2 by the conveying mechanism 5, and the clamping mechanism 7 in the lifting mechanism 2 clamps the workpiece body 6. After clamping, the lifting mechanism 2 drives the clamping mechanism 7 to rise, and the workpiece body 6 is rotated and turned over during the rising process. Then the clamping mechanism 7 releases the workpiece body 6, and the workpiece body 6 slides down to the conveying table 1 by the sliding and descending mechanism 3, and finally the inkjet coding work is carried out.

[0057] Among them, the workpiece body 6 is placed on the conveying table 1 in the conveying table 1. Subsequently, the conveyor belt 51 conveys the workpiece body 6 below the lifting bin 21. During the conveying process, the lifting screw rods 25 in the left and right groups of lifting bins 21 rotate. When rotating, they will drive the lifting blocks 24 to descend. The initial position of the lifting block 24 is at the lower one-third of the bottom of the lifting bin 21. While the lifting block 24 descends, it will drive the clamping box 71 to descend. While the clamping box 71 descends, the connecting gear 751 is driven to rotate by the lifting tooth groove 29 on the side. When the connecting gear 751 rotates, it will drive the clamping screw rod 72 in the clamping box 71 to rotate, thereby driving the clamping block 73 on the clamping screw rod 72 to move towards the workpiece body 6. During the moving process, the workpiece body 6 is clamped through components such as the telescopic column 76 and the clamping plate 78. And a telescopic spring 761 is arranged in the telescopic column 76. When the clamping plate 78 touches the workpiece body 6, the clamping screw rod 72 continues to rotate to drive the clamping plate 78 to move towards the workpiece body 6, thereby squeezing the telescopic spring 761. When the clamping column 77 completely retracts into the telescopic column 76, the lifting block 24 will reach the bottom of the lifting bin 21. At the same time, the lifting screw rod 25 continues to rotate. When rotating, the lifting block 24 will rotate and rise. During the rising process, the workpiece body 6 will be driven to rise together. When rising, the connecting gear 751 will also be driven to rotate by the lifting tooth groove 29. When the connecting gear 751 reaches the initial position and then moves upward, it will reach the upper notch 291 of the lifting tooth groove 29, thereby losing the driving force, and then interrupting the rotation of the connecting gear 751 and the clamping screw rod 72. At the same time, the rotating gear 741 meshes with the lifting tooth groove 29. After meshing, it will drive the clamping box 71 and the whole workpiece to rotate 180° by using the rotating column 74. While flipping, the lifting screw rod 25 continues to rotate, driving the lifting block 24 to rise. When the clamping box 71 and the workpiece body 6 are flipped to 120°, the connecting gear 751 re-meshes and connects with the lifting tooth groove 29. At this time, the clamping screw rod 72 is driven to rotate again, so that the clamping plate 78 moves towards the clamping box 71, slowly releasing the clamping of the workpiece body 6. When the 180° rotation is completed, the workpiece body 6 loses the clamping, so as to realize the flipping of the workpiece body 6 and fall onto the conveying table 1 through the sliding and descending mechanism 3 for the next inkjet coding work. It should be noted that there are a total of an upper notch 291 and a lower notch 292 opened on the lifting tooth groove 29. The lower notch 292 is arranged at the position of the rotating gear 741, that is, when the lifting block 24 drives the clamping box 71 to descend, it will not be able to drive the clamping box 71 to rotate by using the rotating gear 741. The upper notch 291 is arranged at the position of the connecting gear 751, that is, when rising, the clamping of the workpiece body 6 cannot be continuously released. At the same time, when rising from the bottom of the lifting bin 21, since the lifting tooth groove 29 is still meshed with the connecting gear 751 in this section, according to the setting of the telescopic spring 761, the workpiece body 6 can be continuously clamped by the telescopic spring 761 when the clamping plate 78 moves back. When the connecting gear 751 is disengaged from the lifting tooth groove 29, the clamping of the workpiece body 6 is realized by the rebound of the telescopic spring 761.When the connecting gear 751 at the top of the lifting bin 21 is re-engaged, the clamping plate 78 is driven to move back again, completely releasing the workpiece body 6. Through the setting of the clamping mechanism 7, the workpiece body 6 can be clamped by the clamping plate 78 while the conveying table 1 conveys the workpiece body 6. And through the setting of the lifting bin 21, after clamping, the workpiece body 6 can be driven to rise, and at the same time, the workpiece body 6 is driven to flip, realizing the inkjet printing on the other side of the workpiece body 6. After flipping, the workpiece body 6 is put down, and at the same time, the components in the lifting bin 21 return to the initial position again, waiting for the next flipping work of the workpiece body 6, realizing the multi-faceted spraying of the workpiece body 6.
