Description

Technical Field

[0001] The utility model relates to the technical field of paper box packaging machines, in particular to a cam type rotating box suction device for a full-automatic cartoning machine. Background Art

[0002] In modern logistics and packaging industries, cartons are widely used as a packaging material, which is favored by the market for its lightness, easy processing and environmental protection. Cartons are widely used in the outer packaging of various products. They are not only convenient for transportation, but also help to enhance the overall image of the product and promote sales. However, with the continuous expansion of production scale, the traditional packaging method of manually packing items into cartons can no longer meet the needs of mass production. It is inefficient, costly, and easily interfered by human factors, affecting the quality and efficiency of packaging.

[0003] In order to solve this problem, cartoning machines, as an automated packaging equipment, have gradually been introduced into production lines. Cartoning machines can automatically complete a series of operations such as opening the carton, placing items, and sealing the carton, greatly improving packaging efficiency and reducing production costs. However, the use of cartoning machines also faces some technical difficulties, the most critical of which is the problem of opening the carton.

[0004] The cartons shipped from the carton factory are usually flattened and unfolded for easy transportation and storage. Flattened, unformed cartons often have some problems. For example, during the pasting process, there may be slight glue leakage at the bonding points of the cartons. These leaking parts cause the cartons to stick together and cannot be unfolded normally. In addition, if the crease line of the carton is pressed too shallow, the carton is prone to deformation or failure to fully open during the opening process. This puts higher demands on the carton suction and opening device, which needs to accurately control the suction force to avoid the carton shifting, falling, deformation or failure to open due to insufficient or excessive suction force during the suction process.

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] like Figure 1-7 As shown, a cam-type rotary box suction device for a fully automatic cartoning machine is provided with a box suction head base 1, which is fixedly installed on the equipment body, and the box suction head base 1 is fixedly connected to the box suction head cam 2, and the box suction head cam 2 is provided with a plurality of cam grooves 21, the box suction head base 1 is a hollow structure, and a box suction head hollow shaft 3 is provided in the middle of the box suction head base 1, one end of the box suction head hollow shaft 3 is connected to a transmission component 4, and the other end is connected to a box suction head rotating body 5, and at least a pair of box body positive suction components 6 and box body side suction components 7 are provided on the box suction head rotating body 5, and a slide valve component 8 is provided on the transmission component 4, and the slide valve component 8 includes a slide valve core shaft 81 The sliding valve core shaft 81 is fixedly connected to the transmission assembly 4, and at least two sliding valve core shaft air pipe joints are arranged at the front end of the sliding valve core shaft 81. A sliding valve sleeve 82 is arranged outside the sliding valve core shaft 81, and at least two sliding valve sleeve air pipe joints are arranged outside the sliding valve sleeve 82. Sliding valve bearings 83 and sliding valve gaskets are arranged at both ends inside the sliding valve sleeve 82, and a sliding valve spacer sleeve 84 and a sealing ring are arranged in the middle of the sliding valve sleeve 82. The sliding valve sleeve 82 is fixedly connected to the sliding valve end cover 85, and the two sliding valve core shaft air pipe joints are respectively connected to the box body positive suction assembly 6 and the box body side suction assembly 7 through the vacuum air pipe 86, and a sliding valve sleeve fixing assembly 87 is arranged on the sliding valve end cover 85.

[0048] Specifically, the suction box head base 1 is fixedly installed on the equipment body and plays a fixing role. The sliding valve sleeve fixing component 87 is connected to the sliding valve end cover 85, which plays a role in fixing the sliding valve sleeve 82 to prevent it from rotating. The sliding valve core shaft air pipe joint and the sliding valve sleeve air pipe joint are arranged in pairs. The vacuum air pipe 86 passes through the suction box head hollow shaft 3 and is connected to the box body positive suction component 6 and the box body side suction component 7. By setting the sliding valve spacer sleeve 84 and the sealing ring, the sliding valve is divided into several closed air cavities to ensure the sealing between each air cavity and prevent gas cross-flow. The sliding valve sleeve air pipe joint is connected to the vacuum solenoid valve, which is used to control the switching action of the box body positive suction component 6 and the box body side suction component 7. The transmission assembly 4 is connected to the power drive device, and the transmission assembly 4 drives the slide valve core shaft 81 to rotate. When the slide valve core shaft 81 rotates, it will drive the air cavity in the slide valve sleeve 82 to dock with the slide valve sleeve air pipe joints at different positions. Each air cavity corresponds to a slide valve sleeve air pipe joint. By controlling the rotation position of the slide valve core shaft 81, the connection state of different air cavities and the slide valve sleeve air pipe joints can be controlled. When one of the air cavities is connected to the slide valve sleeve air pipe joint, the vacuum solenoid valve controls the slide valve sleeve air pipe joint to be connected to the vacuum air source or the atmosphere, thereby realizing the switch of the corresponding air circuit. For positive suction and side suction, independent control can be achieved by controlling the connection state of different air cavities. That is, when the positive suction air cavity is connected to the slide valve sleeve air pipe joint, the vacuum air source will suck away the air in the air nozzle on the box body positive suction assembly 6, thereby realizing the positive suction function; when the side suction air cavity is connected to the slide valve sleeve air pipe joint, the vacuum pipe interface on the box body side suction assembly 7 will be sucked away by air, realizing the side suction function.

[0049] When the equipment is running, the transmission component 4 drives the hollow shaft 3 of the sucking box head to rotate, thereby driving the rotation of the sucking box head rotating body 5. The plurality of cam grooves 21 provided on the sucking box head cam 2 drive the box body positive suction component 6 and the box body side suction component 7 to move along the track of the cam groove 21 during the rotation of the sucking box head rotating body 5. Figure 6 , 7As shown, the box body positive suction assembly 6 and the box body side suction assembly 7 respectively suck the front and side of the paper box 9. The box body positive suction assembly 6 sucks the front of the paper box 9 under the action of vacuum, while the box body side suction assembly 7 sucks the side of the paper box 9; in this process, the slide valve assembly 8 accurately controls the opening and closing of the vacuum air pipe 86 through the relative movement of the slide valve core shaft 81 and the slide valve sleeve 82. As the box suction head rotating body 5 rotates, the box body positive suction component 6 and the box body side suction component 7 that have sucked the paper box 9 open the paper box 9 and bring it to the designated position, and then release the paper box 9, completing the entire process of sucking, transferring and opening the paper box; subsequently, a new paper box 9 is sucked again, and a new round of circulation begins; by setting the sliding valve component 8 to accurately control the on-off of the gas and the size of the gas flow, the control of the vacuum suction force of the positive suction component 6 and the side suction component 7 is achieved, ensuring the stability and reliability of the paper box 9 during the suction process, avoiding the problem of paper box 9 shifting, falling, deforming or failing to open due to insufficient or excessive suction force, making the entire process more efficient and faster, and improving production efficiency.

[0050] like Figure 8 , 9 As shown, the box body positive suction assembly 6 includes a positive suction rod assembly 61 and a positive suction four-bar assembly 62, the positive suction rod assembly 61 includes a positive suction rod body 611, and a positive suction air nozzle 612 is arranged on the positive suction rod body 611, and the positive suction air nozzle 612 is connected to the suction cup 614 through a suction cup mounting screw 613; the positive suction four-bar assembly 62 includes a first connecting rod 621, a second connecting rod 622, a third connecting rod 623, and a fourth connecting rod 624, the first connecting rod 621 is installed on the suction box head rotating body 5 through a first connecting rod shaft 625, and the first connecting rod shaft 625 is also provided with a A first cam bearing 6251 is provided, and the first cam bearing 6251 is placed in the cam groove 21. The fourth connecting rod 624 is installed on the suction box head rotating body 5 through a second connecting rod shaft 626. The second connecting rod shaft 626 is provided with a second cam bearing 6261, and the second cam bearing 6261 is placed in the cam groove 21. The first connecting rod 621, the second connecting rod 622, the third connecting rod 623, and the fourth connecting rod 624 are hinged in sequence through a connecting rod connecting assembly 627, and the positive suction rod body 611 is fixedly installed on the second connecting rod 622.

[0051] Specifically, the positive suction assembly 6 of the box body absorbs the front of the paper box 9 through the positive suction rod assembly 61, and the positive suction four-link assembly 62 drives the positive suction rod assembly 61 to perform precise movement. The connecting rod connection assembly 627 includes a pin, a bearing, a bearing spacer, and a retaining spring. When the suction box head rotating body 5 rotates, the first cam bearing 6251 slides in the cam groove 21, driving the first connecting rod shaft 621 to rotate, thereby driving the first connecting rod 621 to move, and the second cam bearing 6261 slides in the cam groove 21, driving the second connecting rod shaft 626 to rotate, thereby driving the fourth connecting rod 624 to move. Since the first connecting rod 621, the second connecting rod 622, the third connecting rod 623 and the fourth connecting rod 624 are all hingedly connected, relative movement can be formed between them, thereby realizing the flipping motion trajectory of the positive suction rod assembly 61. By setting up the positive suction four-bar linkage assembly 62, the first cam bearing 6251 and the second cam bearing 6261 slide along the cam groove 21, so as to achieve precise control of the movement trajectory of the positive suction rod assembly 61. The positive suction four-bar linkage assembly 62 makes the movement of the positive suction rod assembly 61 smoother.

[0052] like Fig.10 , 11 As shown, the box body side suction assembly 7 includes a side suction rod assembly 71 and a side suction flip assembly 72, the side suction rod assembly 71 includes a side suction rod body 711, a vacuum tube interface 712 is provided on the side suction rod body 711, the vacuum tube interface 712 is connected to the elliptical suction cup 713, the side suction rod body 711 is connected to the side flip shaft 714, the side flip shaft 714 is rotatably mounted on the suction box head rotating body 5, and a flip pinion 715 is also provided on the side flip shaft 714; the side suction flip assembly 72 includes a fan gear 721, the fan gear 721 is meshed with the flip pinion 715, a side flip bearing 722 is provided in the middle of the fan gear 721, the side flip bearing 722 is rotatably mounted on the suction box head rotating body 5, and a third cam bearing 723 is provided at the tail end of the fan gear 721, and the third cam bearing 723 is placed in the cam groove 21.

[0053] Specifically, the fan gear 721 in the side suction flip assembly 72 is meshed with the flip pinion 715 on the side flip shaft 714. When the fan gear 721 rotates, it drives the flip pinion 715 and the side flip shaft 714 to rotate, thereby driving the side suction rod assembly 71 to perform a flipping movement. The rotation of the fan gear 721 is achieved by the sliding of the third cam bearing 723 at its tail end in the cam groove 21, ensuring the accuracy and stability of the flipping movement. During operation, when the suction box head rotating body 5 rotates to the specified position, the side suction flip assembly 72 starts to work, driving the side suction rod assembly 71 to flip to the appropriate position, so that the elliptical suction cup 713 contacts and adsorbs the side of the paper box 9; the cooperation between the side suction flip assembly 72 and the cam groove 21 ensures the accuracy of the flipping movement of the side suction rod assembly 71, avoiding inadequate or excessive flipping.

[0054] like Fig.12 As shown, the cam groove 21 includes a first cam groove 211, a second cam groove 212, and a third cam groove 213, the first cam bearing 6251 is placed in the first cam groove 211, the second cam bearing 6261 is placed in the second cam groove 212, the third cam bearing 723 is placed in the third cam groove 213, and the cam groove 21 is a closed annular structure.

[0055] Specifically, as the suction box head rotating body 5 rotates, the first cam bearing 6251, the second cam bearing 6261 and the third cam bearing 723 slide in the corresponding first cam groove 211, the second cam groove 212 and the third cam groove 213 respectively, and the closed annular cam groove limits the movement trajectory of the bearings, so that they can move according to the predetermined path. The shapes of the first cam groove 211 and the second cam groove 212 match the movement requirements of the positive suction four-link assembly 62, ensuring that the positive suction rod assembly 61 can move and position according to the predetermined trajectory to achieve accurate suction of the front of the paper box 9; the shape of the third cam groove 213 matches the flipping requirements of the side suction flipping assembly 72, driving the side suction rod assembly 71 to flip. By setting cam grooves of different shapes and positions, precise control of the positive suction assembly 6 and the side suction assembly 7 can be achieved, and each cam bearing slides in the corresponding cam groove to ensure the accuracy and stability of the movement.

[0056] like Figure 2 As shown, the transmission assembly 4 includes a transmission pulley 41, a pulley seat 42 is arranged inside the transmission pulley 41, a flat key slot 43 is arranged on the pulley seat 42, a flat key 44 matching the flat key slot 43 is arranged on the hollow shaft 3 of the suction box head, a front bearing 45 is arranged in the middle of the suction box head cam 2, and a rear bearing 46 is arranged in the middle of the suction box head base 1.

[0057] Specifically, by providing a flat key slot 43 and a flat key 44, the transmission pulley 41 is connected to the hollow shaft 3 of the suction box head to ensure effective transmission of power. The transmission pulley 41 is installed on the pulley seat 42 by bolts to provide rotational power. The transmission pulley 41 drives the pulley seat 42 to rotate, thereby driving the suction box head rotating body 5 to rotate. The front bearing 45 and the rear bearing 46 play a supporting role to ensure the rotation stability and accuracy of the suction box head during operation.

[0058] like Figure 2 As shown, a cover plate 51 is arranged between the suction box head rotating body 5 and the suction box head cam 2, a vacuum tube through hole 52 is arranged in the middle of the suction box head rotating body 5, the vacuum tube through hole 52 is connected to the suction box head hollow shaft 3, and an end cover 53 is arranged on the vacuum tube through hole 52.

[0059] Specifically, the cover plate 51 can prevent external impurities or dust from entering the cam groove 21, keep the interior thereof clean, and improve the safety performance of the device during operation. The hollow shaft 3 of the suction box head is connected to the vacuum tube through hole 52, and the vacuum air pipe 86 passes through the hollow shaft 3 of the suction box head, the vacuum tube through hole 52, and is connected to the box body positive suction component 6 and the box body side suction component 7 in sequence.

[0060] like Figure 1 As shown, there are four of the sliding valve core shaft air pipe joint, the sliding valve sleeve air pipe joint, and the vacuum air pipe 86, and two of the box body positive suction components 6 and the box body side suction components 7.

[0061] Specifically, the four slide valve core shaft air pipe joints, the slide valve sleeve air pipe joints and the vacuum air pipe form four independent channels, which can transmit gas simultaneously or separately. By rationally configuring each component and air pipe joint, the air flow distribution and adsorption effect of the system can be optimized to ensure that each paper box can obtain uniform and stable adsorption force, thereby improving the stability of the entire process.

[0062] This patent application opens the box and transfers the track as follows Figure 7As shown, when the box suction head rotating body 5 turns to the box taking position, due to the counterclockwise rotation of the first cam bearing 6251 and the second cam bearing 6261 along the first cam groove 211 and the second cam groove 212, the positive suction rod assembly 61 sucks the paper box 9 and takes down the paper box 9. With the rotation of the box suction head rotating body 5, the third cam bearing 723 moves along the third cam groove 213, the side suction rod assembly 71 gradually rotates 180°, the elliptical suction cup 713 opens by vacuum, and sucks the side of the paper box 9, gradually flips outward 120°, so that the paper box 9 is reversely pre-folded and opened, which plays a role in pre-forming the paper box 9; with the rotation of the box suction head rotating body 5, the fan gear 721 drives the side flip bearing 722 to rotate in the opposite direction, so that the paper box 9 is close to the row state when it reaches the box placing position. When it reaches the box placing position, the vacuum solenoid valve first closes the box body positive suction assembly 6, and then closes the box body side suction assembly 7, so as to facilitate the box placing, and complete the work flow of box taking-suction box-paper box pre-folding-paper box forming-box placing.

[0063] The present application discloses a cam-type rotary box suction device for a fully automatic cartoning machine. By setting a sliding valve assembly 8 to accurately control the on-off and gas flow rate of the gas, the vacuum suction force of the positive suction assembly 6 and the side suction assembly 7 is controlled, the stability and reliability of the paper box 9 during the suction process are ensured, and the problems of the paper box 9 shifting, falling, deforming or failing to open due to insufficient or excessive suction force are avoided, so that the whole process is more efficient and faster, and the production efficiency is improved; by setting a positive suction four-bar connecting rod assembly 62, the first cam bearing 6251 and the second cam bearing 6261 slide along the cam groove 21, so as to realize the precise control of the movement trajectory of the positive suction rod assembly 61, and the positive suction four-bar connecting rod assembly 62 makes the movement of the positive suction rod assembly 61 more stable. In the present application, the box body positive suction component 6 adopts a four-bar connection method to realize the flipping trajectory. The four-bar mechanism has great flexibility of movement, and the flipping trajectory can be changed by adjusting the length of the connecting rod and the position of the connection point to adapt to paper boxes of different shapes and sizes; the box body side suction component 7 realizes the flipping movement of the paper box 9 by swinging the fan gear 721, and the paper box is transferred and flipped by combining the box body positive suction component 6 and the box body side suction component 7. It can adapt to different flipping requirements, improve flipping efficiency and accuracy, optimize spatial layout, and enhance the reliability of the equipment, making the entire box suction head assembly more efficient, stable and flexible.
