Description

Technical Field

[0001] The present invention relates to the technical field of packaging box making machines, and more particularly to a packaging box making machine capable of moving toward a center point. Background Art

[0002] With the continuous development of commodity economy, the packaging industry plays a vital role in modern business. As an important carrier for protecting commodities, displaying commodity information and increasing commodity added value, the demand for packaging boxes is growing and the requirements are constantly improving. In the process of making packaging boxes, packaging box making machines are usually used to assist in the production of packaging boxes.

[0003] However, the existing packaging box making machine has the following problems when in use:

[0004] (1) In the traditional packaging box production field, the structure of many box making machines is relatively fixed, which makes it difficult to adapt to the production needs of packaging boxes of different sizes and shapes. In the packaging molding and production process of different packaging boxes, a lot of time and resources need to be invested to adjust the equipment or replace the mold, which not only reduces production efficiency but also increases production costs. In addition, in the clamping process, mechanical methods are still used, which is easy to cause damage to the packaging box. In particular, for some packaging boxes made of soft materials and easy to deform, the traditional gripping method may cause creases and damage to the packaging box, affecting the integrity and aesthetics of the product;

[0005] (2) Secondly, traditional box-making machines are not accurate enough in positioning the packaging boxes. They are unable to adjust the center point of the packaging machine in real time according to each different packaging box. This can easily cause the packaging box to deviate during the clamping process, affecting the quality and appearance of the product.

[0018] Beneficial effects:

[0019] 1. A double-headed screw rod, a slide rail and a connecting plate are provided, and a motor is used to drive the double-headed screw rod to rotate through a transmission wheel and a transmission belt. Since the double-headed screw rod is threadedly connected to the mechanical arm, the mechanical arm can move along the axial direction of the double-headed screw rod. The auxiliary chain is engaged with the rear of the packaging machine to provide additional support and guidance for the mechanical arm. During the movement of the mechanical arm, the auxiliary chain can limit the movement direction of the mechanical arm to prevent it from deflecting or shaking, ensuring that the movement of the mechanical arm is more stable and accurate. The slide rail provides a stable track for the movement of the connecting plate. Through the movement of the connecting plate, the position of the auxiliary arm inside the mechanical arm can be adjusted to perform operations such as grabbing and carrying the packaging box, so that it can better adapt to the production requirements of packaging boxes of different sizes and shapes;

[0020] 2. The cylinder and the suction nozzle are provided. The cylinder provides a power source for the action of the suction nozzle. In the process of grabbing the unformed packaging box, the cylinder can accurately control the extension and contraction movement of the suction nozzle. When the packaging box needs to be grabbed, the cylinder starts to push the suction nozzle to approach the unformed packaging box. The suction nozzle generates adsorption force through negative pressure to achieve the grabbing of the unformed packaging box. When the suction nozzle contacts the packaging box, a negative pressure environment is formed inside, which firmly adsorbs the packaging box and carries it to a designated location for molding or places it on the production belt for transportation. Through negative pressure adsorption, it can adapt to packaging boxes of different materials and surface characteristics, ensure the firmness of grabbing, and avoid the damage to the packaging box that may be caused by traditional mechanical grabbing methods;

[0021] 3. By providing a second slide rail, a limit block and a rotating rod handle, the second slide rail is fixedly installed on the front and rear sides of the upper end of the base and is slidably connected to the bottom of the packaging machine, providing a clear guide for the movement of the packaging machine, ensuring that the packaging machine can slide smoothly along a specific path when adjusting its position without deviation or shaking. After the position of the packaging machine is determined, the limit block can cooperate with the rotating rod handle to further enhance the stability of the packaging machine. When the rotating rod handle rotates and is stuck on the second slide rail, the limit block can prevent the packaging machine from being slightly displaced due to external force, ensuring that the packaging machine will not move or deviate during packaging operations;

[0022] 4. In summary, this type of movable center-point packaging box making machine, by providing structures such as a mechanical arm, an auxiliary arm and a base, can adjust the center point of the packaging machine through the base to make it consistent with the center point of the packaging box, so as to better clamp the packaging box. Under the action of a double-headed screw, the mechanical arm can move precisely in the horizontal direction, and through the drive of a motor, it can achieve operations of approaching or moving away from each other, so as to better complete the tasks of grasping and carrying the packaging box. The auxiliary arm can extend and retract back and forth on the inside of the mechanical arm, and cooperate with the mechanical arm to meet the needs of making packaging boxes of different sizes and shapes. The suction nozzle on the auxiliary arm can ensure the stability and safety of the packaging box during the grasping process, avoiding the damage to the packaging box that may be caused by traditional grasping methods.

In the middle of the forming roller 3, a connecting plate 406 is slidably installed on the inner side of the mechanical arm 4, and the base 5 is installed on the front and rear sides of the production belt 1 respectively, and then the packaging machine 2 is installed on the base 5, and the bottom of the packaging machine 2 is slidably connected to the base 5. The bottom of the packaging machine 2 is fixedly installed with a bottom plate 201 at the bottom of the inside of the packaging machine 2, and then the forming machine 202, the packaging box forming roller 3 and the mechanical arm 4 can be installed on the bottom plate 201. The packaging box forming roller 3 and the mechanical arm 4 are both slidably connected to the forming machine 202 and can move left and right in the forming machine 202, and the top rod 301 and the packaging box forming roller 3 form a complete packaging box forming device, and the inner side of the mechanical arm 4 slides A connecting plate 406 is connected, and the connecting plate 406 can be extended and retracted forward and backward on the inner side of the mechanical arm 4 to meet the production needs of packaging boxes of different sizes and shapes. In the box making process, the unformed packaging box is first placed on the production belt 1, and the unformed packaging box is transported to the front of the packaging machine 2 through the production belt 1. At this time, the position of the center point between the packaging machine 2 and the unformed packaging box can be adjusted through the sliding connection between the base 5 and the packaging machine 2 to ensure that the center point of the packaging machine 2 is consistent with the center point of the unformed packaging box. Then, the mechanical arm 4 is expanded to both sides, and then the connecting plate 406 is extended forward, and then the mechanical arm 4 is retracted inward to make the connecting plate 406 extend forward. Plate 406 can grab the unformed packaging box, then retract the connecting plate 406 and move the unformed packaging box between the packaging box forming roller 3 and the top rod 301. The packaging box forming rollers 3 on the front, back, left and right sides and the middle top rod 301 cooperate with each other under the drive of the forming machine 202 to extrude and form the packaging box from different directions. When the packaging box is initially formed, the robot arm 4 repeats the initial grabbing action to grab the packaging box, and then moves toward the production belt 1, places the formed packaging box on the production belt 1, and is transported by the production belt 1, and then continues to grab other unformed packaging boxes for molding.

[0031] In the embodiment of the present invention, a double-headed screw 203 is provided on the front and back of the molding machine 202, a motor 204 is fixedly installed below the double-headed screw 203, a transmission wheel 205 is provided on the left side of the double-headed screw 203 and the left output end of the motor 204, a transmission belt 206 is provided between the two transmission wheels 205, the double-headed screw 203 is threadedly connected with the mechanical arm 4, and a double-headed screw 203 is provided on the front and back of the molding machine 202. The function of the double-headed screw 203 is mainly to provide a moving track and power for the mechanical arm 4. Through the rotation of the double-headed screw 203, the mechanical arm 4 can be accurately moved in the horizontal direction, the stability and accuracy of the mechanical arm 4 during the movement process can be ensured, and the moving direction of the mechanical arm 4 can be made more accurate and stable, so as to better complete the operations of grabbing and carrying the packaging box. When in use, The transmission wheel 205 on the output end is driven by a motor 204 to rotate, and the other transmission wheel 205 is driven to rotate through a transmission belt 206, thereby rotating the double-headed screw 203. The rotation of the double-headed screw 203 causes the mechanical arm 4 threadedly connected thereto to move along the axial direction of the double-headed screw 203, thereby achieving operations of approaching or moving away from each other. When it is necessary to grab the packaging box, the two mechanical arms 4 are first moved away from each other by the rotation of the motor 204 to prevent the connecting plate 406 on the inner side of the mechanical arm 4 from touching the packaging box when it is extended. After the mechanical arms 4 are moved away from each other, the connecting plate 406 is extended, and then the motor 204 is reversed to move the two mechanical arms 4 closer to each other, so that the connecting plate 406 can approach the packaging box and grab the packaging box. The mechanical arm 4 with the connecting plate 406 can better adapt to the sizes and positions of different packaging boxes.

[0032] In the embodiment of the present invention, double-headed screw rods 207 are arranged at the front and rear sides of the molding machine 202.

A transmission belt 209 is arranged between the transmission wheels 208 of the double-headed screw rods 207 on the same side. The top rod 301 is a multi-section telescopic rod type, and the output end passes through the bottom plate 201 and the bottom of the molding machine 202, and is arranged in conjunction with the packaging box molding roller 3. An auxiliary device 302 is arranged above the top rod 301. The auxiliary device 302 and the top rod 301 are combined into a packaging box film forming auxiliary mechanism. When the packaging box is transported to the packaging box molding roller 3, the transmission wheel 208 is rotated by the driving of the molding machine 202, and the transmission wheel 208 rotates. The double-headed screw rod 207 is driven to rotate, and the other double-headed screw rod 207 is rotated through the transmission belt 209. Since the double-headed screw rod 207 is threadedly connected with the packaging box forming rollers 3 on the left and right sides inside the forming machine 202, the rotation of the double-headed screw rod 207 will drive the packaging box forming rollers 3 on the left and right sides to move along the axial direction of the double-headed screw rod 2, so as to achieve the preliminary adjustment of the left and right positions of the packaging box forming rollers 3, so as to make them close to the unformed packaging box or away from the unformed packaging box.

In the process of grabbing the unformed packaging box, when the robot arm 4 moves to the two sides, the suction nozzle 413 is fixedly installed on the cylinder 412. When the side is opened, the motor 2 403 is started, driving the transmission wheel 3 401 to rotate, thereby moving the transmission belt 3 402, and the transmission belt 3 402 drives the connecting plate 406 to move forward along the slide rail 1 404. According to the size and shape of the unformed packaging box, the connecting plate 406 can adjust the position of the connecting plate 406 through the movement of the transmission belt 3 402. When the connecting plate 406 reaches the specified position, the robot arm 4 moves toward the middle and approaches each other, so that the connecting plate 406 is close to the unformed packaging box. After that, the motor 3 411 is started, and the motor 3 411 drives the screw rod 410 to rotate. 9 is threadedly connected to the screw rod 410, and the slider 409 is slidably connected to the slide rail 408. Therefore, when the screw rod 410 rotates, the slider 409 moves on the screw rod 410 along the track of the slide rail 408, thereby adjusting the position of the cylinder 412 so that the cylinder 412 can position the unformed packaging box. After that, the cylinder 412 is started to push the suction nozzle 413 toward the unformed packaging box. After the suction nozzle 413 contacts the unformed packaging box, it generates adsorption force through negative pressure to firmly grasp the unformed packaging box, and then the connecting plate 406 is retracted inward for subsequent molding work.
