DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] Example 1: Reference Figure 1 and Figure 2 A packaging conveying device includes: a frame 1, a conveyor belt mechanism 2, a second conveyor belt mechanism 3 and a guide plate 4. The frame 1 is equipped with a frame 2 on the side, the conveyor belt mechanism 2 is installed on the frame 1, and the conveyor belt mechanism 2 is installed on the frame 2. The top of the second conveyor belt mechanism 3 is coplanar with the top of the conveyor belt mechanism 2. A guide plate 4 is installed on each side of the second conveyor belt mechanism 3, and the guide plate 4 is connected to the mounting frame 2.

[0033] The principles of the above scheme are:

[0034] When conveying the packaging boxes, start the conveyor belt mechanism 2 on the frame 1, and at the same time start the conveyor belt mechanism 2 3 on the frame 2. The frame 2 is installed on the side of the frame 1, and the guide plate 4 is connected to the mounting frame 2. A guide plate 4 is installed on each side of the conveyor belt mechanism 2 3. The conveyor belt mechanism 2 3 can replenish the packaging boxes of the latter when the conveyor belt mechanism 2 is working.

[0035] The beneficial effects of the above scheme are:

[0036] A frame 2 is provided on the side of the frame 1, a conveyor belt mechanism 2 is installed on the frame 1, and a conveyor belt mechanism 2 3 is installed on the frame 2. The conveyor belt mechanism 2 3 cooperates with the conveyor belt mechanism 2 to convey the packaging boxes. By adding a merging device, namely the conveyor belt mechanism 2 3, the continuity and stability of the conveyor belt mechanism 2 in conveying the packaging boxes are improved;

[0037] In the process of replenishing the packaging boxes, the guide plate 4 can cooperate with the conveyor belt mechanism 2 3 to provide auxiliary guidance and direction for the packaging boxes;

[0038] At the same time, since the top end of the conveyor belt mechanism 2 3 is arranged coplanar with the top end of the conveyor belt mechanism 2, the packaging box will not overturn after the packaging box is replenished.

[0039] Example 2: Reference Figure 1-Figure 2 A merging guide plate 5 is installed on the guide plate 4, one end of the merging guide plate 5 is placed above the conveyor belt mechanism 2 3, and the other end of the merging guide plate 5 is placed above the conveyor belt mechanism 2 and is arranged toward the output end of the conveyor belt mechanism 2.

[0040] The principles of the above scheme are:

[0041] The top end of the merging guide plate 5 is connected to the guide plate 4, and one end of the merging guide plate 5 is arranged above the conveyor belt mechanism 2 3. The merging guide plate 5 is arranged above the conveyor belt mechanism 2 and is arranged toward the output end of the conveyor belt mechanism 2. The part of the merging guide plate 5 placed above the conveyor belt mechanism 2 is a curved arc.

[0042] The beneficial effects of the above scheme are:

[0043] The supplemented packaging boxes are guided by the merging guide plate 5 and the conveyor belt mechanism 2 3 and are input into the conveyor belt mechanism 2. Since the part of the merging guide plate 5 arranged above the conveyor belt mechanism 2 is a curved arc, the change of movement direction can be completed after the supplemented packaging boxes enter the conveyor belt mechanism 2; at the same time, the merging guide plate 5 is provided to assist in improving the movement stability of the packaging boxes supplemented into the conveyor belt mechanism 2, and further avoid the risk of the packaging boxes overturning after merging.

[0044] Example 3: Reference Figure 2 、 Figure 3 and Figure 4 The frame 1 is provided with a plurality of mounting frames 6, the mounting frames 6 are slidably connected with sliders, the screw holes at the top of the sliders are threadedly connected with screw rods 7, the bottom ends of the screw rods 7 are in contact with the top ends of the mounting frames 6, and the bottom ends of the sliders are provided with guide plates 8.

[0045] The bottom ends of the screw holes are arranged toward the top surface of the installation frame 6 .

[0046] The principles of the above scheme are:

[0047] The mounting frame 6 is installed on the frame 1. When it is necessary to adjust the angle between the guide plate 2 8 and the belt conveying direction of the conveyor belt mechanism 2, the screw rod 7 is rotated counterclockwise, and the bottom end of the screw rod 7 is disengaged from the contact and cooperation with the top surface of the mounting frame 6, so that the slider can slide freely relative to the mounting frame 6. The operator can adjust the position of the guide plate 2 8 at the input end of the conveyor belt mechanism 2 and the position of the guide plate 2 8 at the output end of the conveyor belt mechanism 2 according to actual requirements, and then adjust the angle between the guide plate 2 8 and the conveying direction of the conveyor belt mechanism 2, so that the packaging boxes after the merging and the packaging boxes before the merging are adjusted in accordance with the actual production needs. After the adjustment is completed, the screw rod 7 is rotated counterclockwise, and the bottom end of the screw rod 7 is again in contact and cooperated with the top surface of the mounting frame 6, thereby fixing the position of the guide plate 2 8.

[0048] The beneficial effects of the above scheme are:

[0049] The second guide plate 8 is provided to facilitate the producer to adjust the conveying route of the packaging box;

[0050] The slider is provided to be slidably connected to the mounting frame 6 , the screw hole on the slider is threadedly connected to the screw rod 7 , and the bottom end of the screw rod 7 contacts and cooperates with the top surface of the mounting frame 6 , so as to facilitate rapid adjustment of the position of the guide plate 2 8 .

[0051] Example 4: Reference Figure 1 , multiple legs are installed at the bottom ends of rack 1 and rack 2.

[0052] The principles of the above scheme are:

[0053] Install the feet on the bottom ends of rack 1 and rack 2.

[0054] The beneficial effects of the above scheme are:

[0055] By providing the support legs, the contact area between the frame 1 and the frame 2 and the ground at the work site is increased, thereby improving the overall stability of the device.

[0056] Example 5: Reference Figure 1 and Figure 4 A roller 9 is provided at each end of the frame 1. Both ends of the roller 9 are rotatably connected to the bearing seat 10. The bearing seat 10 is installed on the frame 1. The rollers 9 are connected by belt transmission. The end of one roller 9 is connected to the output end of the motor. The motor is installed on the frame 1. The frame 1 is equipped with a tension adjustment mechanism 11. The tension adjustment mechanism 11 is in rolling cooperation with the belt. The roller 9, the bearing seat 10, the motor and the belt constitute a conveyor belt mechanism 2.

[0057] The conveyor belt mechanism 2 3 has the same structure as the conveyor belt mechanism 2 .

[0058] The principles of the above scheme are:

[0059] When the packaging box is conveyed, the motor is started, and the output end of the motor drives the end of a roller 9 to rotate. The roller 9 is rotatably installed on the bearing seat 10 of the frame 1. The two rollers 9 are connected by a belt. The belt and the tension adjustment mechanism 11 are rollingly matched, and the frame 1 fixes the tension adjustment mechanism 11.

[0060] The beneficial effects of the above scheme are:

[0061] When the distance between the two rollers 9 is large and the belt conveying distance is long, a tension adjustment mechanism 11 is set on the frame 1 to facilitate the control of the belt tension at all times, to prevent slipping between the belt and the roller 9, and to avoid adding a roller 9 connected to the motor output end to the frame 1 to maintain the belt conveying capacity. The installation of the motor is reduced in the device, which greatly saves the production cost.

[0062] Example 6: Reference Figure 5 The bearing seat 10 includes: a shell 12 and a bearing ring 13. The shell 12 is installed on the frame 1. A plurality of balls are embedded in the circular hole of the shell 12. The inner wall of the circular hole slides with the side wall of the bearing ring 13. The side wall of the bearing ring 13 is circumferentially provided with an annular groove. The annular groove slides with the balls. One end of the circular hole 2 is opened on the inner wall of the annular groove. The other end of the circular hole 2 is opened on the inner wall of the bearing ring 13. The mounting shaft of the roller 9 is inserted into the inner wall of the bearing ring 13. A storage cavity is provided inside the mounting shaft and the roller 9. The storage cavity is filled with lubricating oil. The end of the circular hole 3 is opened in the storage cavity. The other end of the circular hole 3 is arranged toward the other end of the circular hole 2.

[0063] The principles of the above scheme are:

[0064] A storage chamber is provided inside the mounting shaft and the roller 9, and the storage chamber is filled with lubricating oil. When the device is working, the roller 9 rotates synchronously with the mounting shaft, and the mounting shaft drives the bearing ring 13 connected thereto to rotate synchronously. The lubricating oil enters the circular hole 2, the annular groove and the circular hole in sequence through the circular hole 3 on the storage chamber to lubricate the ball.

[0065] The beneficial effects of the above scheme are:

[0066] The storage chamber is opened in the drum 9 and the mounting shaft to greatly reduce the weight of the drum 9;

[0067] At the same time, the lubricating oil in the storage chamber can lubricate the balls, and can also lubricate the inner wall of the circular hole and the side wall of the bearing ring 13, which can always maintain the best lubrication effect between the components, thereby preventing wear between the components;

[0068] Since lubricating oil is filled in the storage chamber, when the roller 9 is installed on the bearing ring 13 of the bearing seat 10, the bearing ring 13 and the circular hole of the shell 12 can be automatically lubricated, which reduces the maintenance frequency of the device and saves time for device inspection and maintenance.

[0069] Example 7: Reference Figure 6 A plurality of fan blades 14 are installed at the end of the drum 9, and a plurality of heat sinks 15 are horizontally provided on both sides of the shell 12. The heat sinks 15 on both sides of the shell 12 are vertically provided with heat sink 2, and the ends of the heat sink 2 are arranged toward the fan blades 14.

[0070] The principles of the above scheme are:

[0071] The rotation of the drum 9 drives the fan blades 14 to rotate. A plurality of heat sinks 15 are horizontally installed on both sides of the shell 12. The heat sink 15 is perpendicular to the heat sink 2. The ends of the heat sink 15 are arranged toward the fan blades 14. An air circulation channel is formed between the two heat sinks 2.

[0072] The beneficial effects of the above scheme are:

[0073] When the drum 9 rotates, the bearing ring 13 and the housing 12 rotate relative to each other, and the lubricating oil will generate friction with the components to generate heat. By installing heat sinks 15 on both sides of the housing 12, the heat dissipation area of ​​the housing 12 is increased;

[0074] The heat sink 15 and the second heat sink are arranged perpendicular to each other, further increasing the heat dissipation area of ​​the housing 12;

[0075] The second heat sink is arranged parallel to the side of the housing 12. The second heat sink cooperates with the housing 12 and the plurality of heat sinks 15 to form a plurality of heat dissipation holes on the side of the housing 12. When the device finishes working, since the end of the second heat sink faces the fan blade 14, the end of the second heat sink is cooled first, thereby generating a temperature difference between the two ends of the second heat sink. Due to the existence of the temperature difference, the air at the two ends of the heat dissipation hole is subjected to different temperatures. Further, due to the temperature difference, the air in the heat dissipation hole begins to flow, which not only facilitates auxiliary cooling of the housing 12, but also further accelerates the heat dissipation speed of the housing 12, the heat sink 15 and the second heat sink, so as to prevent the parts from scalding the operator after the work is completed;

[0076] The specific installation position of the fan blades 14 at the end of the drum 9 is that they are arranged in a circular array with the installation circumference of the drum 9 as the center. One end of the fan blades 14 is adjacent to the installation shaft, and the other end of the fan blades 14 faces the side wall of the drum 9. Since an air circulation channel is formed between the two heat sinks 2, the end of the fan blades 14 is adjacent to the installation shaft. When the drum 9 drives the fan blades 14 to rotate, the air pressure near the side wall of the installation shaft is low. Therefore, the air around the outer shell 12 can enter the vicinity of the installation shaft through the heat dissipation holes, and then be discharged through the air circulation channel. In the process of air flowing through the heat dissipation holes, the heat of the heat sink 15 and the heat sink 2 is absorbed by the flowing air and finally discharged through the air circulation channel. At the same time, the flowing air can dissipate heat to the installation shaft.

[0077] Example 8: Reference Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 , the inner wall of the circular hole is provided with an end of a circular hole four, the other end of the circular hole four is provided on the housing 12, the other end of the circular hole four is connected to the end of the pipe, the other end of the pipe is connected to the end of the tank body 16, the tank body 16 is mounted on the frame 1, and a piston 17 is slidingly sealed in the tank body 16. The side wall of the piston 17 is in conduction with the circular hole five on the tank body 16, the circular hole five is connected to the end of the pipe two, the end of the piston 17 is connected to a rod body 18, the rod body 18 is slidingly sealed with the circular hole six at the other end of the tank body 16, and a spring 19 is installed between the end of the piston 17 and the circular hole six;

[0078] A buffer chamber is formed between the end of the piston 17 facing the pipe and the tank body 16, and the buffer chamber, the pipe and the circular hole 4 are all filled with lubricating oil.

[0079] The end of the rod body 18 placed outside the tank body 16 is equipped with the end of the guide rod, the other end of the guide rod is slidably connected to the longitudinal guide groove on the end face of the disc, the disc is rotatably connected to the frame 1, and the bottom end of the rod body 20 is hinged on the disc. The longitudinal guide groove is provided on the upper part of the end face of the disc, and the bottom end of the rod body 20 is placed below the rod body 18.

[0080] The tension adjustment mechanism 11 includes: roller 21, roller 3 22, spring 23 and spring 3 24. The top surface of the lower part of the belt is rollingly matched with roller 21. A roller 3 22 is provided on each side of roller 21. Roller 3 22 is rolling matched with the bottom surface of the lower part of the belt. Each end of roller 21 is rotatably connected to a bearing seat 2. The two sides of bearing seat 2 are slidingly connected to the frame 1. The top end of bearing seat 2 is connected to the frame 1 through spring 23. The bottom end of a bearing seat 2 is hinged to the top hinge of rod body 20. Each side of roller 3 22 is rotatably connected to a bearing seat 3. The two sides of bearing seat 3 are slidingly connected to the frame 1. The bottom end of bearing seat 3 is connected to the frame 1 through spring 3 24.

[0081] The principles of the above scheme are:

[0082] After the device starts working or when the ambient temperature around the device rises, the belt expands due to heat, and the friction between the belt and the roller 9 generates a large amount of heat. The lubricating oil that absorbs the heat expands in volume, pushing the sliding sealed piston 17 in the tank body 16 to move in the direction away from the pipeline. The spring 19 is compressed, and the piston 17 drives the rod body 18 to move. The end of the rod body 18 outside the tank body 16 is equipped with the end of a guide rod. The other end of the guide rod is slidably connected to the longitudinal guide slot. The guide rod moves downward relative to the longitudinal guide slot. At the same time, the guide rod drives the disc to rotate clockwise, and the bottom end of the rod body 20 hinged to the disc moves downward. The top of the rod body 20 drives a bearing seat 2 and a roller 21 rotatably connected thereto to move downward. The spring 23 is stretched, applying tension to the belt.

[0083] After the device finishes working or when the ambient temperature around the device drops, the belt temperature drops, and then shrinks, the volume expansion of the lubricating oil decreases, the piston 17 moves toward the pipe, the elastic force of the spring 19 is released, the piston 17 drives the rod body 18 to move, and the guide rod on the end of the rod body 18 placed outside the tank body 16 is slidably connected to the longitudinal guide slot, the guide rod moves upward relative to the longitudinal guide slot, and at the same time the guide rod drives the disc to rotate counterclockwise, the bottom end of the rod body 20 hinged to the disc moves upward, the top end of the rod body 20 drives a bearing seat 2 and a roller 21 rotatably connected thereto to move downward, the spring 23 is stretched, and the tension applied to the belt is reduced;

[0084] When the belt is subjected to tension or tension reduction, the bearing seat three to which the roller three 22 is rotatably connected moves downward or upward, and the height of the spring three 24 decreases or increases.

[0085] The beneficial effects of the above scheme are:

[0086] A tank body 16 is provided, and a buffer chamber in the tank body 16 is filled with lubricating oil, which can absorb the heat of the lubricating oil from the shell 12 through a pipeline. The lubricating oil in the buffer chamber cooperates with the spring 19 to buffer the movement of the rod body 18. When the device needs to adjust the tension of the belt, all the lubricating oil in the buffer chamber needs to be heated and expanded before the rod body 18 can be driven to move, and then the tension applied to the belt by the roller 21 is controlled through the rod body 20. Because the device is provided with a buffering measure before applying the tensioning force of the belt or reducing the tensioning force of the belt, the belt is prevented from jumping due to a sudden change in the tensioning force of the belt, or the belt is prevented from moving relative to the roller 9, thereby improving the stability of the belt during the transportation of the packaging box, preventing the packaging box from overturning during the transportation process, and at the same time improving the stability of the belt during operation, thereby ensuring the safety of the device during operation;

[0087] By arranging the rod body 18 to be placed outside the tank body 16, a guide rod is installed at the end thereof, the guide rod is slidably connected to the longitudinal guide groove on the disc, and the rod body 20 is hinged to the disc respectively, so that the existing parts are fully utilized in actual production, and at the same time, the transmission effect and transmission efficiency between the parts are improved.

[0088] Example 9: Reference Figure 10-12 The other end of the pipe 2 is connected to one end of the coil 25. The coil 25 is equipped with a plurality of heat sinks 3 26. The heat sink 3 26 is installed on the shell 2. The shell 2 is arranged between the upper and lower parts of the belt. The opening of the bottom end of the shell 2 is arranged toward the lower part of the belt. The top surface of the belt is provided with the tops of a plurality of conical holes 31. The bottom ends of the conical holes 31 are connected to the tops of the air guide holes 32. The inner diameter of the bottom ends of the conical holes 31 is larger than the inner diameter of the top ends. The bottom ends of the air guide holes 32 are opened on the bottom surface of the belt. An air inlet is provided on the top surface of the shell 2. A plurality of rod bodies 3 are rotatably connected to the shell 2. The top ends of the rod bodies 3 are equipped with pulleys 27. The bottom ends of the rod bodies 3 are connected to the fan blades 28. The air inlet faces the fan blades A second blade 28 is provided, and the bottom end of the second blade 28 is arranged toward the coil 25. A pulley 2 is rotatably connected to the frame 1. A motor 2 is installed on the frame 1. A pulley 3 29 is installed at the output end of the motor 2. The pulley 3 29, the pulley 2 and the plurality of pulleys 27 are connected through a belt 2 30. The other end of the coil 25 is connected to one end of a pipe 3. A one-way valve is installed in the pipe 3 to prevent the lubricating oil from flowing back into the coil 25. A liquid pump device is installed in the pipe 3. The liquid pump device is arranged between the other end of the coil 25 and the one-way valve. The other end of the pipe 3 is connected to the circular hole 4 of another bearing seat 10. The other bearing seat 10 is rotatably connected to the mounting shaft at the other end of the drum 9.

[0089] Pipeline 2, coil 25 and pipeline 3 are all filled with lubricating oil.

[0090] The principles of the above scheme are:

[0091] When the temperature of the lubricating oil in the tank body 16 continues to rise, the piston 17 continues to move away from the pipeline, and then the pipeline 2 is opened. The lubricating oil in the pipeline 2 and the coil 25 is heated and the temperature rises. The motor 2 is started, and the pulley 3 29 at the output end of the motor 2 rotates. The pulley 3 29 drives multiple pulleys 27 to rotate at the same time through the belt 2 30. The pulley 2 provides guidance when the belt 2 is transmitted. The rotation of the pulley 27 drives the rod body 3 to rotate, and the rotation of the rod body 3 drives the fan blade 2 28 to rotate. The air passes through the tapered hole 31 and the air guide hole 32 on the upper part of the belt, and cools the coil 25 through the fan blade 28. The lubricating oil in the coil 25 is cooled, and the heated air is discharged through the air guide hole 32 and the tapered hole 31 on the lower part of the belt. The cooled lubricating oil flows through the one-way valve in the pipeline 3 under the guidance of the liquid pump device, so that the temperature of the lubricating oil in the circular hole 4 of the other bearing seat 10 is reduced, thereby reducing the temperature of the lubricating oil at the other end of the drum.

[0092] The beneficial effects of the above scheme are:

[0093] When the fan blade 28 rotates, it draws air from the tapered hole 31 on the upper part of the belt, causing the air pressure on the top surface of the belt to decrease, so that the packaging box can be adsorbed on the belt when conveying the packaging box;

[0094] At the same time, since the inner diameter of the top of the tapered hole 31 is smaller than the inner diameter of the bottom, the air is drawn in by the second fan blade 28 and the air distribution area on the second housing is increased, thereby increasing the contact area between the air and the coil 25.

[0095] The air that has absorbed heat is discharged through the air guide holes 32 and the tapered holes 31 at the bottom of the belt. At this time, the discharged hot air is gathered by the top of the tapered hole 31, and the flow rate is accelerated. The hot air with increased flow rate can remove impurities and dirt on the surface of the belt, thereby improving the cleanliness of the device.

[0096] At the same time, the hot air that absorbs heat can increase the local temperature of the top of the tapered hole 31 on the belt, thereby sterilizing the local part of the belt. Since the thickness of the intersection of the top of the tapered hole 31 and the top surface of the belt is low, the temperature can be quickly reduced after the hot air is discharged, which can avoid the rubber denaturation of the belt due to excessive temperature.

[0097] A one-way valve is installed in pipe three to prevent pipe three from diverting the lubricating oil in the pipeline, thereby avoiding affecting the device's adjustment of the belt tension, and further avoiding the belt's overheating and reduced conveying capacity. While improving the rationality of the device, it also improves the practicality of the device.

[0098] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
