Technical Field

[0001] The utility model relates to the technical field of packaging box making machines, and more particularly to an automatic box holding mechanism of the packaging box making machine. Background Art

[0002] With the continuous development of the commodity economy, the packaging industry plays a vital role in modern commerce. As an important carrier for protecting goods, displaying product information, and enhancing product added value, the demand for packaging boxes is growing and the requirements are constantly improving. During the packaging box production process, box making machines are often used to assist in the production and shaping of the boxes. When using box making machines, they usually require a robot or manual grasping of the unformed boxes.

[0003] However, the packaging box grabbing mechanism of 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.

[0016] Beneficial effects:

[0017] 1. The stud-screw and auxiliary chain provide a precise trajectory and power source for the robotic arm. Motor 1 drives stud-screw 1 via drive wheel 1 and drive belt 1. Because the robotic arm is threadedly connected to stud-screw 1, the robotic arm can precisely adjust its position horizontally. The auxiliary chain, meshing with the rear of the packaging machine, provides additional support and guidance for the robotic arm's movement. During movement, the auxiliary chain limits the robotic arm's direction, preventing it from shifting or shaking. This ensures the robotic arm can accurately move to the desired position during different work phases and improves stability during movement.

[0018] 2. By providing a screw, a second slide rail, and a second slider, when the screw rotates, since the second slider is rotatably connected to the screw thread, when the screw rotates, the second slider is prompted to move along the axial direction of the screw. The second slider slides on the surface of the second slide rail, ensuring the stability and directionality of the second slider during movement. The second slide rail cooperates with the screw, on the one hand, limiting the movement direction of the second slider so that it can only move along the length direction of the second slide rail. On the other hand, it reduces the friction resistance during the movement of the second slider, making the movement of the second slider smoother and more efficient, thereby driving the cylinder to reach the appropriate position;

[0019] 3. By setting up a cylinder and a suction nozzle, when it is necessary to grab a package, the cylinder is activated, which can quickly and accurately push the suction nozzle close to the package. The pushing force and speed can be adjusted according to different package sizes and materials to ensure that the suction nozzle can closely contact the package. The suction nozzle grabs the package through negative pressure adsorption. When the suction nozzle contacts the package, a negative pressure environment is formed inside, generating a strong adsorption force to firmly grasp the package. Compared with traditional mechanical grippers, the negative pressure adsorption method of the suction nozzle is more gentle and will not cause damage to the package.

[0020] 4. In summary, the automatic box holding mechanism of this box making machine is equipped with structures such as a robotic arm, a connecting plate and a suction nozzle. The robotic arm moves precisely in the horizontal direction and adjusts its position according to different work requirements, approaching or moving away from the packaging box. During the grabbing process, the opening and retraction of the robotic arm can create space for the operation of the connecting plate and the suction nozzle, and ensure that they can accurately grab the packaging box. The connecting plate can slide stably on the slide rail one inside the robotic arm through the transmission belt three. The position of its extension and retraction can be flexibly adjusted according to the size and shape of the packaging box to better cooperate with the suction nozzle for grabbing operations. The suction nozzle adsorbs the packaging box through negative pressure adsorption, which avoids damage to the packaging box. At the same time, its strong adsorption force ensures the stability of grabbing. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is a combination of the appended examples of the present invention Figures 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0027] See also Figure 1-4In the embodiment of the present invention, an automatic box holding mechanism of a packaging box making machine includes: a packaging machine 1, three packaging box forming rollers 2 are slidably installed inside the packaging machine 1, mechanical arms 3 are provided on the left and right sides above the packaging box forming rollers 2, and a connecting plate 4 is slidably installed on the inner side of the mechanical arm 3. A bottom plate 101 is fixedly installed at the bottom of the packaging machine 1, and a forming machine 102 is fixedly installed on the upper end of the bottom plate 101. The packaging box forming rollers 2 are respectively installed on the front, left and right sides of the upper bottom end of the forming machine 102. A push rod 201 is provided on the rear side of the bottom plate 101. The push rod 201 is a multi-section telescopic rod type, and the output end passes through the bottom plate 101 and the bottom of the forming machine 102, and is matched with the packaging box forming roller 2. , double-headed screw rod 2 107 is provided at the front and rear of the molding machine 102, double-headed screw rod 2 107 is located below double-headed screw rod 1 103, and is respectively threadedly connected to the packaging box forming roller 2 on the left and right sides of the molding machine 102, and the left and right ends of double-headed screw rod 2 107 pass through the left and right ends of the molding machine 102, and a transmission wheel 2 108 is provided at the end, and a transmission belt 2 109 is provided between the transmission wheels 2 108 of the double-headed screw rod 2 107 on the same side. The packaging machine 1 provides space for installation and operation of the entire mechanism. The packaging box forming roller 2 is composed of three rollers, which are driven by the packaging machine 1 to work and can extrude the unformed packaging box from three different directions, and is matched with the push rod 2 01 Extrusion molding is performed on the unformed packaging box to ensure that the shape and size of the packaging box are accurate. The mechanical arm 3 and the connecting plate 4 above it form a complete packaging box grabbing structure, which can grab packaging boxes of different specifications and sizes. When in use, the unformed packaging box is first transported to the front of the packaging machine 1, and the mechanical arm 3 is opened to both sides, and then the connecting plate 4 is moved toward the packaging box. During the movement, the mechanical arm 3 is retracted inward again, so that the connecting plate 4 can grab the packaging box, and then the connecting plate 4 is retracted toward the packaging machine 1, and the packaging box is moved between the packaging box forming roller 2 and the push rod 201. At this time, the forming machine 102 is driven by the packaging machine 1. Drive the transmission wheel 2 108 to rotate, and the transmission wheel 2 108 drives the double-headed screw 2 107 to rotate. Since the double-headed screw 2 107 is threadedly connected to the packaging box forming rollers 2 on the left and right sides inside the forming machine 102, the double-headed screw 2 107 on both sides is rotated synchronously through the transmission belt 2 109, thereby driving the packaging box forming rollers 2 on the left and right sides to move along the axial direction of the double-headed screw 2 107, so as to achieve precise adjustment of the left and right positions of the forming rollers to adapt to packaging boxes of different sizes, and then push it upward with the push rod 201 to extrude and form the unformed packaging box from different directions, gradually shaping it into the required shape, and then transport the formed packaging box outward through the robotic arm 3 and the connecting plate 4.

[0028] In the embodiment of the present invention, a double-headed screw 103 is provided on the front and back of the molding machine 102, a motor 104 is fixedly installed below the double-headed screw 103, a transmission wheel 105 is provided on the left side of the double-headed screw 103 and the output end of the left side of the motor 104, a transmission belt 106 is provided between the two transmission wheels 105, the double-headed screw 103 is threadedly connected to the robot arm 3, and an auxiliary chain 301 is provided on the rear side of the upper end of the robot arm 3. The auxiliary chain 301 is engaged with the rear of the packaging machine 1. When the robot arm 3 is opened and retracted, the double-headed screw 103 provides a moving track and power for the robot arm 3, and the motor 104 is started. The motor 104 is connected to the robot arm 3 through the transmission wheel 105 and the transmission belt 106. 106 drives the double-headed screw 103 to rotate. Since the double-headed screw 103 is threadedly connected to the robot arm 3, the robot arm 3 can move precisely in the horizontal direction, so that the robot arms 3 can move closer or farther away from each other. The choice of approaching or moving away is based on the needs of the current workflow. When grabbing the packaging box, the robot arms 3 are first moved away from each other. When the connecting plate 4 is extended, the robot arms 3 are moved closer to each other. In this process, the auxiliary chain 301 engages with the rear of the packaging machine 1, providing additional support and guidance for the robot arm 3. During the movement of the robot arm 3, the auxiliary chain 301 can limit the moving direction of the robot arm 3 to prevent it from offsetting or shaking, ensuring that the movement of the robot arm 3 is more stable and accurate.

[0029] In the embodiment of the present invention, a transmission wheel three 302 is rotatably installed on the front and rear sides of the inner side of the robot arm 3, a transmission belt three 303 is provided between the transmission wheels three 302, a motor three 304 is fixedly installed on the front side of the outer end face of the robot arm 3, the output end of the motor three 304 is fixedly connected to the transmission wheel three 302 on the front side of the robot arm 3, a slide rail 1 305 is fixedly installed on the upper and lower sides of the inside of the robot arm 3, a connecting plate 4 is slidably provided on the slide rail 1 305, the slide rail 1 305 is respectively provided on the upper and lower sides of the transmission belt three 303, the outer side surface of the connecting plate 4 is fixedly connected to the transmission belt three 303 on either side of the upper and lower sides, a slider 1 401 is fixedly installed on the upper and lower sides of the outer side surface of the connecting plate 4, the slider 1 401 is slidably connected to the slide rail 1 305, when the robot arm 3 is extended outward, After opening, when the connecting plate 4 needs to be extended outward to grab the packaging box, the motor three 304 is started, and the motor three 304 drives the transmission wheel three 302 on the inner front side of the mechanical arm 3 to rotate, thereby moving the transmission belt three 303. When the transmission belt three 303 moves, since one side of the connecting plate 4 is connected to any upper or lower side of the transmission belt three 303, the movement of the transmission belt three 303 will drive the connecting plate 4 to move. The sliding connection between the slider one 401 and the slide rail one 305 makes the connecting plate 4 more stable during the movement and determines the movement direction of the connecting plate 4. Therefore, when the motor three 304 rotates forward, the connecting plate 4 can be extended outward. When the motor three 304 rotates reversely, the connecting plate 4 is retracted inward, realizing the movement of the connecting plate 4 after grabbing the packaging box.

[0030] In the embodiment of the present invention, a fixing plate 402 is provided on the inner side of the connecting plate 4, a slide rail 2 403 is fixedly installed in the middle of the inner side of the fixing plate 402, a plurality of sliders 2 404 are slidably installed on the surface of the sliders 2 403, a screw 405 is rotatably installed between the sliders 2 404, a motor 406 is provided at the rear end of the screw 405, and is fixedly connected to the output end of the motor 406, two cylinders 407 are provided on the front side of the screw 405, a suction nozzle 408 is provided at the rear end of the cylinder 407, and the cylinder 407 is installed at the bottom of the slider 2 404. When the connecting plate 4 is extended outward to carry out the packaging box grabbing work, the motor Four 406 is started, and motor four 406 drives screw 405 to rotate. Since slider two 404 is threadedly connected to screw 405, and slider two 404 is slidingly connected to slide rail two 403, the rotation of screw 405 will drive slider two 404 to move, thereby driving cylinder 407 to move, and adjusting the position of cylinder 407 so that it can move around its packaging box. After that, cylinder 407 is started, pushing suction nozzle 408 toward the packaging box. After suction nozzle 408 contacts the packaging box, it firmly grasps the packaging box through negative pressure adsorption, and then drives the packaging box to move, so that it is extruded into shape.

[0031] Working Principle: When using this device to grab a package, the unformed package is first delivered to the packaging machine 1. Then, Motor 104 is started, which rotates double-headed screw 103 via drive wheel 105 and drive belt 106. Because double-headed screw 103 is threadedly connected to the robotic arm 3, the robotic arm 3 can move precisely in the horizontal direction, moving the two robotic arms 3 away from each other and towards each other. Auxiliary chain 301 engages with the rear of the packaging machine 1, providing additional support and guidance for the robotic arms 3, ensuring the stability and accuracy of their movement. When the robotic arms 3 move away from each other and open, Motor 3 304 is started, which drives drive wheel 3 302 on the inner front side of the robotic arm 3, thereby moving drive belt 3 303. Since the outer side of the connecting plate 4 is fixedly connected to the transmission belt 3 303 and is slidably connected to the slide rail 1 305 inside the robot arm 3 through the slider 1 401, the movement of the transmission belt 303 drives the connecting plate 4 to move stably inside the robot arm 3, thereby realizing the extension and retraction of the connecting plate 4. When the connecting plate 4 is extended, the two robot arms 3 are brought closer to each other, and then the motor 406 is started. The motor 406 drives the screw 405 to rotate. Since the slider 2 404 is threadedly connected to the screw 405 and is slidably connected to the slide rail 2 403, the rotation of the screw 405 drives the slider 2 404 to move on the slide rail 2 403. The robot arm 3 is moved upward, thereby adjusting the position of the cylinder 407 installed at the bottom of the slider 2 404 so that the cylinder 407 can be located around the unformed packaging box. The robot arm 3 is then continuously moved closer so that the suction nozzle 408 on the cylinder 407 can contact the packaging box. The suction nozzle 408 then firmly grasps the packaging box through negative pressure adsorption. At this time, the motor 304 is reversed, and the connecting plate 4 is retracted inward and transported to the packaging box forming roller 2 for packaging box forming. After the packaging box is formed, the packaging box is adsorbed by the same method and then transported outward and placed on the production belt for transportation.
