Abstract
Description
Technical Field
[0001] This invention relates to the field of packaging equipment technology, and in particular to a bagging packaging machine. Background Technology
[0002] The three-dimensional bagging packaging machine is an advanced packaging equipment that integrates automated bag feeding, precise bagging, and efficient sealing. Through processes such as crease forming, material filling, and longitudinal and transverse sealing, it can process packaging materials into a three-dimensional shape and tightly wrap the product. It features beautiful packaging, high efficiency, and strong adaptability, and can be widely used in many industries such as food, pharmaceuticals, daily chemicals, and electronics. It not only meets the product protection needs such as moisture protection, dust protection, and shock protection, but also improves the product display effect and significantly reduces labor costs. It is an important piece of equipment for achieving efficient packaging in modern production lines.
[0003] Currently, most bag-opening packaging machines use vacuum suction cups for their opening mechanisms. The suction cups adhere to the film on both sides of the bag opening, and then a robotic arm or cylinder drives the suction cups to move in the opposite direction to open the bag. This method is effective when handling airtight or low-permeability packaging bags such as plastic films and composite films, as it relies on the stable negative pressure created between the suction cups and the bag opening for reliable adsorption, resulting in a high success rate.
[0004] The existing technology has the following drawbacks:
[0005] In the packaging industry, some products (such as textiles, home textiles, and certain medical consumables) require packaging bags made of breathable fabrics (such as gauze bags, non-woven bags, and woven bags). When dealing with these breathable fabric packaging bags, existing vacuum suction cup-based bag-opening structures have significant drawbacks: due to the breathability of the fabric itself, the suction cup cannot create an effective sealing negative pressure when adsorbing the bag opening, resulting in insufficient suction force and difficulty in stably gripping the bag opening; simultaneously, after processing or stacking, the bag opening of breathable fabric packaging bags often becomes tightly sealed due to fiber entanglement or environmental humidity, further increasing the difficulty of separating the bag opening. These problems directly lead to an increased bag-opening failure rate, manifested as the bag opening not being fully opened, unstable shape after opening, or bag opening misalignment, resulting in problems such as misaligned bagging and unqualified packaging, seriously affecting the overall working efficiency and packaging quality of three-dimensional bagging packaging machines. Summary of the Invention
[0006] Given the problem that packaging bags made of breathable fabric are difficult to open in existing technologies, a bagging packaging machine is proposed.
[0007] This application provides a bagging packaging machine, the purpose of which is to improve the gripping method so that it can open various types of packaging bags.
[0008] The technical solution of the present invention is as follows: a bagging packaging machine, comprising two machine bodies, a control component disposed on the outside of the machine body, an installation rail disposed at the bottom of the control component, an adsorption component disposed on the inside of the installation rail, the control component specifically comprising a control rod, a guide rod and an extension frame disposed on the surface of the machine body, a connecting rod disposed on the outside of the control rod, a connecting platform disposed at the bottom of the connecting rod, an auxiliary spring disposed on the outside of the guide rod, an adjustment hole opened at the top of the extension frame, an inner platform disposed inside the adjustment hole, a support frame disposed between the inner platform and the extension frame, and a deflection rod disposed on the outside of the control rod;
[0009] The connecting platform is fixed to the top of the mounting rail, the guide rod is inserted into the mounting rail, the control rod is located above the extension frame, the inner wall of the adjustment hole and the outer wall of the inner platform form a control slide, the control slide is divided into three parts: an opening section, a flared section and a reset section, and these three parts form a ring, with the deflection rod inserted into the control slide.
[0010] Furthermore, the control slide has a triangular outline, with a reset section located at the bottom of the triangular outline and an opening section and a flared section located at the waist.
[0011] Furthermore, the control slide has a trapezoidal outline, with a reset section distributed at the bottom of the trapezoidal outline, an opening section distributed at one of the waist sections, and a flared section distributed at the other waist section and the top bottom section.
[0012] Furthermore, the control rod specifically comprises three parts: a main cylinder, a middle piston rod, and an end piston rod;
[0013] The middle piston rod is inserted into the main cylinder, the end piston rod is inserted into the middle piston rod, the deflection rod is connected to the middle piston rod, and the connecting rod is connected to the end piston rod.
[0014] Furthermore, the outer wall of the inner platform and the inner wall of the adjustment hole are both set to be arc-shaped, so that the width of the control slide gradually widens from the middle to the upper and lower sides.
[0015] Furthermore, the adsorption assembly specifically includes a main rod disposed within the mounting rail, a suction cup disposed at one end of the main rod, an air guide tube disposed at the other end of the main rod, and a fixing component disposed on the outside of the main rod.
[0016] Furthermore, the fixing component specifically includes a fixed sleeve and a movable sleeve disposed on the outside of the main rod, the movable sleeve and the fixed sleeve fitting against both sides of the mounting rail.
[0017] Furthermore, the adsorption assembly also includes a conductive contact plate and an electrostatic contact plate disposed on the inner side of the main rod, two terminals disposed on the outer side of the main rod, an inner rod disposed on the inner side of the main rod, a contact plate disposed on the outer side of the inner rod, a support spring disposed on one end of the inner rod, and an adsorption platform disposed on the other end of the inner rod.
[0018] The electrostatic contact plate is located at the end of the conductive contact plate near the adsorption stage. Two terminals pass through the main rod and are inserted into the conductive contact plate and the electrostatic contact plate respectively. The contact plate is in contact with the conductive contact plate or the electrostatic contact plate. The adsorption stage is located inside the suction cup.
[0019] Furthermore, the adsorption assembly also includes a vent hole disposed inside the inner rod, a side hole disposed outside the inner rod, and a sealing bolt disposed inside the vent hole;
[0020] A piston sleeve is provided at the top of the inner rod, a vent hole passes through the inner rod, a side hole communicates with the vent hole, and a sealing bolt is located at the junction of the side hole and the vent hole.
[0021] The beneficial effects of this invention are:
[0022] 1. By setting up a control component, the control rod pushes the adsorption component close to the packaging bag through the connecting rod, connecting platform and mounting rail to adsorb it. Then the control rod retracts and is guided by the control slide. The deflection rod deflects to one side, thereby driving the control rod to rotate. Due to the restriction of the guide rod, the mounting rail cannot tilt. With the cooperation of the rotation points at both ends of the connecting rod, the mounting rail slides horizontally to one side and then pulls backward. This action of first "rubbing" at the bag opening and then opening it simulates the action of manually opening the bag, which helps to open packaging bags that are half-open and tightly sealed.
[0023] 2. By setting a triangular control slide, when the deflection rod slides within the control slide, it moves to the opening section, and the adsorption component moves diagonally backward to open the packaging bag opening. When it moves to the widening section, the adsorption component pulls back significantly to fully open the packaging bag opening. When it moves to the reset section, the packaging bag after the opening is removed, and the adsorption component moves towards the new packaging bag. This control method is simple and convenient, has high working efficiency, and a low failure rate.
[0024] 3. By setting a trapezoidal control slide, when the deflection rod slides in the control slide, it moves in the opening section. The end piston rod and the middle piston rod are stretched to counteract their backward pulling force. The mounting rail only drives the adsorption component to deflect to one side, which makes the friction at the opening of the packaging bag greater and the kneading opening effect better. When it moves in the flaring section, the adsorption component pulls back significantly to open the packaging bag completely. When it moves in the reset section, the packaging bag after opening is taken away, and the adsorption component moves towards the new packaging bag.
[0025] 4. By setting up the adsorption assembly, during normal use, rotating the sealing bolt lowers it, opening the side hole. This connects the upper and lower parts of the piston sleeve, and the air pressure inside the main rod does not affect the inner rod. With the support of the support spring, the inner rod cannot move, and the adsorption platform is completely housed inside the suction cup, thus forming an air pressure adsorption state for airtight packaging bags. Rotating the sealing bolt raises it, sealing the side hole, and the upper and lower parts of the piston sleeve are disconnected. The air pressure inside the main rod begins to affect the inner rod, pushing it to move. The inner rod then pushes the adsorption platform to the suction cup opening. The contact plate moves synchronously with the inner rod and contacts the electrostatic contact plate. The electrostatic contact plate connects to the contact plate, generating static electricity on the surface of the inner rod and the adsorption platform for adsorbing breathable packaging bags. Subsequently, the air pressure controls the inner rod to reset, and the contact plate connects with the conductive contact plate, transferring the charge and eliminating the static electricity.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0043] Example 1, referring to Figures 1-9 The first embodiment of the present invention provides a bagging packaging machine, comprising two machine bodies 1, a control component 2 disposed on the outside of the machine body 1, a mounting rail 3 disposed at the bottom of the control component 2, and an adsorption component 4 disposed on the inside of the mounting rail 3. The control component 2 specifically includes a control rod 21, a guide rod 24 and an extension frame 26 disposed on the surface of the machine body 1, a connecting rod 22 disposed on the outside of the control rod 21, a connecting platform 23 disposed at the bottom of the connecting rod 22, an auxiliary spring 25 disposed on the outside of the guide rod 24, an adjustment hole 27 opened at the top of the extension frame 26, an inner platform 28 disposed inside the adjustment hole 27, a support frame 29 disposed between the inner platform 28 and the extension frame 26, and a deflection rod 210 disposed on the outside of the control rod 21.
[0044] Specifically, the two machine bodies 1 are symmetrically distributed. The product packaging bag is offset between the two mounting rails 3. The adsorption component 4 is connected to an external air pump. The control rod 21 is rotatably connected to the machine body 1. The top end of the connecting rod 22 is rotatably connected to the control rod 21. The bottom end of the connecting rod 22 is rotatably connected to the connecting platform 23. The connecting platform 23 is fixed to the top of the mounting rail 3. The guide rod 24 is inserted into the mounting rail 3 and slides within the mounting rail 3. One end of the auxiliary spring 25 rests against the surface of the mounting rail 3. The control rod 21 is located above the extension frame 26. The inner wall of the adjustment hole 27 and the outer wall of the inner platform 28 form a control slide. The control slide is divided into three parts: an opening section, a flared section, and a reset section. These three parts form a ring. The vertex A of the outer contour at the junction of the opening section and the reset section is located on the side of the vertex B of the inner contour. This ensures that the deflection rod 210 can move along the prescribed path. The deflection rod 210 is inserted into the control slide.
[0045] By setting up control component 2, control rod 21 pushes adsorption component 4 close to the packaging bag through connecting rod 22, connecting platform 23 and mounting rail 3 to adsorb it. Then control rod 21 retracts and is guided by control slide. Deflection rod 210 deflects to one side, thereby driving control rod 21 to rotate. Due to the restriction of guide rod 24, mounting rail 3 cannot tilt. With the cooperation of the rotation points at both ends of connecting rod 22, mounting rail 3 slides horizontally to one side and is then pulled backward. This action of first "rubbing" at the bag opening and then opening it simulates the action of manually opening the bag, which helps to open a packaging bag that is half-open and tightly sealed.
[0046] Specifically, the outer wall of the inner platform 28 and the inner wall of the adjustment hole 27 are both set to be arc-shaped, so that the width of the control slide gradually widens from the middle to the upper and lower sides, so that the deflection rod 210 will not be blocked by the inner wall of the control slide when it tilts in the control slide.
[0047] Example 2, refer to Figures 1-7 and Figure 9 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the contour of the control slide is triangular, wherein the reset section is distributed at the bottom of the triangular contour, and the opening section and the flaring section are distributed at the waist.
[0048] By setting up a triangular control slide, when the deflection rod 210 slides within the control slide, it moves to the opening section, and the adsorption component 4 moves diagonally backward, pulling and rubbing to open the packaging bag opening. When it moves to the flaring section, the adsorption component 4 pulls back significantly to fully open the packaging bag opening. When it moves to the reset section, the packaging bag after the opening is removed, and the adsorption component 4 moves towards the new packaging bag. This control method is simple and convenient, has high working efficiency, and a low failure rate.
[0049] The remaining structure is the same as that in Example 1.
[0050] Example 3, referring to Figures 1-8 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that the contour of the control slide is trapezoidal, wherein the reset section is distributed at the bottom of the trapezoidal contour, the opening section is distributed at one of the waist sections, and the flared section is distributed at the other waist section and the top bottom section.
[0051] Specifically, the control lever 21 comprises three parts: the main cylinder 211, the middle piston rod 212, and the end piston rod 213.
[0052] The middle piston rod 212 is inserted into the main cylinder 211 and its extension and retraction are controlled by air pressure followed by oil pressure. The end piston rod 213 is inserted into the middle piston rod 212 and slides into the middle piston rod 212. A spring is installed between the two, and the force required to compress this spring is less than the force required to compress the auxiliary spring 25. The deflection rod 210 is connected to the middle piston rod 212, and the connecting rod 22 is connected to the end piston rod 213.
[0053] By setting a trapezoidal control slide, when the deflection rod 210 slides in the control slide, it moves in the opening section. The end piston rod 213 and the middle piston rod 212 are stretched to counteract their backward pulling force. The mounting rail 3 only drives the adsorption component 4 to deflect to one side, which makes the friction at the opening of the packaging bag greater and the kneading opening effect better. When it moves in the flaring section, the adsorption component 4 pulls back significantly to open the packaging bag completely. When it moves in the reset section, the packaging bag after opening is taken away, and the adsorption component 4 moves towards the new packaging bag.
[0054] The remaining structure is the same as that in Example 2.
[0055] Example 4, refer to Figures 10-14 This is the fourth embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adsorption component 4 specifically includes a main rod 41 disposed in the mounting rail 3, a suction cup 42 disposed at one end of the main rod 41, an air guide tube disposed at the other end of the main rod 41, and a fixing member 43 disposed on the outside of the main rod 41. The fixing member 43 specifically includes a fixing sleeve 431 and a movable sleeve 432 disposed on the outside of the main rod 41.
[0056] The main rod 41 passes through the mounting rail 3, the fixed sleeve 431 is fixedly connected to the main rod 41, the movable sleeve 432 is threadedly connected to the fixed sleeve 431, and the movable sleeve 432 and the fixed sleeve 431 fit against both sides of the mounting rail 3.
[0057] By setting the fixing piece 43, the main rod 41 can be installed on the mounting rail 3, and the position of the main rod 41 can be flexibly adjusted to adapt to the size of the packaging bag.
[0058] The adsorption assembly 4 also includes a conductive contact plate 44 and an electrostatic contact plate 45 disposed on the inner side of the main rod 41, two terminals 46 disposed on the outer side of the main rod 41, an inner rod 47 disposed on the inner side of the main rod 41, a contact plate 49 disposed on the outer side of the inner rod 47, a support spring 48 disposed at one end of the inner rod 47, and an adsorption platform 410 disposed at the other end of the inner rod 47.
[0059] Specifically, the conductive contact plate 44, the electrostatic contact plate 45, and the contact plate 49 are all C-shaped. The electrostatic contact plate 45 is located at the end of the conductive contact plate 44 near the adsorption platform 410. Two terminals 46 pass through the main rod 41 and are inserted into the conductive contact plate 44 and the electrostatic contact plate 45 respectively. One of the two terminals 46 is connected to the power supply to generate static electricity, and the other is grounded to quickly transfer the charge. The outer contour of the contact plate 49 protrudes outward to contact the conductive contact plate 44 or the electrostatic contact plate 45. The adsorption platform 410 is located inside the suction cup 42. The adsorption platform 410 is frustum-shaped, which can increase the adsorption area.
[0060] The adsorption assembly 4 also includes a vent 411 disposed inside the inner rod 47, a side hole 412 disposed outside the inner rod 47, and a sealing bolt 413 disposed inside the vent 411.
[0061] Specifically, a piston sleeve is provided at the top of the inner rod 47, a vent hole 411 passes through the inner rod 47, a side hole 412 communicates with the vent hole 411, and a sealing bolt 413 is located at the junction of the side hole 412 and the vent hole 411.
[0062] By setting the adsorption component 4, during normal use, rotating the sealing bolt 413 causes it to move downward, opening the side hole 412. This connects the upper and lower parts of the piston sleeve, and the air pressure inside the main rod 41 does not affect the inner rod 47. With the support of the support spring 48, the inner rod 47 cannot move, and the adsorption platform 410 is completely housed in the suction cup 42, thus forming an air pressure adsorption state for airtight packaging bags. Rotating the sealing bolt 413 causes it to move upward, sealing the side hole 412, and the upper and lower parts of the piston sleeve are disconnected. The air pressure inside the main rod 41 begins to affect the inner rod 47, pushing the inner rod 47 to move. The inner rod 47 pushes the adsorption platform 410 to the opening of the suction cup 42. The contact plate 49 moves synchronously with the inner rod 47 and contacts the electrostatic contact plate 45. The electrostatic contact plate 45 connects the contact plate 49, causing static electricity to be generated on the surfaces of the inner rod 47 and the adsorption platform 410, which is used to adsorb breathable packaging bags. Subsequently, the air pressure controls the inner rod 47 to reset, and the contact plate 49 connects with the conductive contact plate 44. The charge is transferred, and the static electricity disappears.
[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
