[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Please see the appendix Figures 1 to 3 As shown: This invention provides an M-bag packaging machine, including a frame 1, an M-bag loading device 2 installed inside the frame, and a finished product packaging device 3 located on one side of the M-bag loading device 2. The M-bag packaging machine also includes a detection mechanism 4 and a bag-supporting mechanism 5. The detection mechanism 4 is vertically and vertically inserted into the opening end of the M-bag loading device 2 to detect whether there is a shortage of material when the bag is opened. The bag-supporting mechanism 5 is located between the detection mechanism 4 and the finished product packaging device 3, and is used to expand the M-bags transported from the M-bag loading device 2 outwards. After the detection mechanism 4 detects that there is a bag at the opening end of the M-bag loading device 2, it transports the bag to the empty position of the bag-supporting mechanism 5. The bag-supporting mechanism 5 then inserts into the M-bag and expands it outwards to complete the opening. Finally, the finished product packaging device 3 outputs the product after loading and sealing. By adding the detection mechanism 4 and the bag-supporting mechanism 5, the reliability and efficiency of the packaging process are significantly improved. The detection mechanism 4 is vertically and insertably mounted at the opening end of the M-bag loading device 2. It can accurately detect whether there is a shortage of material when the bag is opened, avoiding ineffective packaging operations caused by material shortage and saving packaging materials and time costs. The bag-supporting mechanism 5 is located between the detection mechanism 4 and the finished product packaging device 3. It can fully expand the M-bag to all sides, providing good conditions for subsequent feeding and sealing processes, making the entire packaging process smoother and effectively improving packaging efficiency and quality.
[0028] Based on the above embodiments, the detection mechanism 4 includes a detection bracket 41 fixed inside the frame 1. A lifting drive source 42 is rotatably mounted on the detection bracket 41 to provide power for the lifting of the detection base. A detection base 43 is movably mounted on one side of the detection bracket 41, and the lifting drive source 42 can drive the detection base 43 to move back and forth. Detection arms 44 are oscillating on the detection base 43, capable of moving closer or further apart. A detection sensor 45 is mounted at one end of each detection arm 44 to sense the oscillation state of the detection arm 44. When the detection arm 44 contacts the packaging bag, the detection sensor 45 can detect its oscillation change, thereby determining whether there is a packaging bag at the opening end of the M-bag loading device 2. The specific structural design of the detection mechanism 4 results in accurate detection. The detection bracket 41, fixed inside the frame 1, provides stable support for the entire detection mechanism. The lifting drive source 42 can drive the detection base 43 to move back and forth, allowing the detection arm 44 to accurately insert into the opening end of the M-bag loading device 2. The detection arms 44 can swing and move closer or further apart. When they come into contact with the packaging bag, they swing. The detection sensor 45 can keenly sense this swing state, thereby accurately determining whether there is a packaging bag at the open end, which greatly improves the accuracy of material shortage detection.
[0029] Based on the above embodiment, the bag-supporting mechanism 5 includes a bag-supporting bracket 51 located on one side of the detection mechanism 4. A second lifting drive source 52 is rotatably mounted on the bag-supporting bracket 51, and a bag-supporting seat 53 is movably mounted on one side of the bag-supporting bracket 51. The second lifting drive source 52 can drive the bag-supporting seat 53 to reciprocate vertically. Front and rear bag-supporting components 54 are movably mounted on the bag-supporting seat 53, and left and right bag-supporting components 55 are movably mounted on the front and rear bag-supporting components 54. Through the coordinated movement of the front and rear bag-supporting components 54 and the left and right bag-supporting components 55, the M-shaped packaging bag can be fully expanded in all directions. The bag-supporting bracket 51 provides a stable support foundation for the entire mechanism, and the second lifting drive source 52 can drive the bag-supporting seat 53 to reciprocate vertically, enabling the bag-supporting mechanism to be accurately inserted into the M-shaped packaging bag. The front and rear bag-supporting components 54 and the left and right bag-supporting components 55 provided on the bag support base 53 can open the packaging bag from both front and rear and left and right directions, realizing the all-round opening of the packaging bag and ensuring the fullness and uniformity of the opening of the packaging bag.
[0030] Based on the above embodiments, the front and rear bag-supporting components 54 include front and rear support bars slidably disposed at the bottom of the bag-supporting base 53 via linear guides. The arrayed front and rear support bars are driven by a servo motor via a lead screw to move closer or further apart, thereby expanding the packaging bag in the front-to-back direction. The left and right bag-supporting components 55 include bag-supporting arms slidably disposed at the bottom of the front and rear support bars. Adjacent bag-supporting arms are driven by a second servo motor via a lead screw to move closer or further apart, thereby expanding the packaging bag in the left-to-right direction. The second lifting drive source 52 is a belt drive assembly, which has the advantages of smooth transmission and high efficiency.
[0031] The specific structural design of the front and rear bag-supporting components 54 and the left and right bag-supporting components 55 makes the bag-supporting operation more precise and efficient. The front and rear support bars are slidably mounted on the bottom of the bag-supporting base 53 via linear guides, and are driven by servo motors through lead screws to move closer or further apart, enabling precise control of the opening force and range in the front-to-back direction. The bag-supporting arms are slidably mounted on the bottom of the front and rear support bars, and are driven by a second servo motor through lead screws to move closer or further apart, achieving precise opening in the left-to-right direction. The second lifting drive source 52 adopts a belt drive assembly, which has the advantages of smooth transmission and low noise, ensuring stable and reliable lifting movement of the bag-supporting base 53, further improving the bag-supporting effect and quality.
[0032] Based on the above embodiments, a fixture block is detachably installed at the end of the bag-supporting arm, and the contact surface between the fixture block and the packaging bag has a rounded corner transition. This design can reduce the damage to the packaging bag caused by the bag-supporting arm when opening the packaging bag, thereby improving the yield rate of the packaging. The detachable fixture block at the end of the bag-supporting arm facilitates the replacement and maintenance of the fixture block. When the fixture block is worn or damaged, it can be replaced in a timely manner, ensuring the normal operation of the bag-supporting process. The rounded corner transition design of the contact surface between the fixture block and the packaging bag can effectively avoid scratches or damage to the packaging bag during the opening process, improving the integrity rate of the packaging bag and thus improving the quality of the packaged products.
[0033] Based on the above embodiments, the M-bag loading device 2 includes a conveying device 21 mounted inside the frame 1 for transporting M-packaged bags. Between adjacent conveying devices 21 is a bag opening assembly 22 for opening the bag opening. Below the bag opening assembly 22, a tilting bag-picking device 23 is vertically movably mounted, and at the starting end of the tilting bag-picking device 23 is a movably mounted bag positioning device 24. Symmetrically arranged on both sides of the bag positioning device 24 are vertically movably raised bag storage components 25. Above the bag storage components 25 and the bag positioning device 24, a movably mounted bag-picking robot 26 is positioned. Through the coordinated operation of these components, the loading, positioning, and retrieval of M-packaged bags are achieved. The structural design of the M-bag loading device 2 enables efficient loading and positioning of M-packaged bags. The conveying device 21 can stably transport M-packaged bags, and the bag opening assembly 22 can promptly open the bag opening, preparing for subsequent processes. The tilting bag-picking device 23 can be tilted and lifted, and can tilt to pick up the bag, achieving accurate gripping and placement of the packaged bag. The packaging bag positioning device 24 can accurately position the packaging bag, ensuring the accuracy of subsequent bag opening and packaging operations. The bag storage component 25 can be lifted vertically, facilitating bag retrieval by the bag-picking robot 26 and improving bag loading efficiency. The coordinated operation of the entire device ensures the high efficiency and accuracy of the bag loading process.
[0034] Based on the above embodiments, the flipping bag-retrieving device 23 includes a lifting bag-retrieving component, the output end of which is equipped with a servo flipping component. The lifting bag-retrieving component can drive the servo flipping component to move back and forth vertically. The output end of the servo flipping component is equipped with a packaging bag gripping component, which can drive the packaging bag gripping component to swing back and forth, thereby accurately gripping and flipping the packaging bag. The specific structural design of the flipping bag-retrieving device 23 makes the bag-retrieving and flipping operations more flexible and precise. The lifting bag-retrieving component can drive the servo flipping component to move back and forth vertically, accurately reaching the bag-retrieving position and taking out the packaging bag. The servo flipping component can drive the packaging bag gripping component to swing back and forth, realizing the flipping of the packaging bag, allowing the packaging bag to enter the subsequent process in a suitable posture, improving the continuity and efficiency of the packaging process.
[0035] Based on the above embodiments, the finished product packaging device 3 includes a feeding device 31 for introducing raw materials into M-bags. A vacuuming device 32 is vertically movable on one side of the feeding device 31 to remove gas from the packaging bag, improving the product's shelf life. A sealing device 33 is located on one side of the vacuuming device 32 for sealing the finished product. A discharge assembly 34 is vertically movable below the sealing device 33 to transport the sealed finished product out of the M-bag packaging machine, completing the entire packaging process. The structural design of the finished product packaging device 3 integrates raw material feeding, vacuuming, sealing, and discharge. The feeding device 31 accurately introduces raw materials into the M-bags, ensuring sufficient product packaging quantity. The vertically movable vacuuming device 32 effectively vacuums the packaging bag, extending the product's shelf life. The sealing device 33 reliably seals the finished product, preventing leakage. The vertically movable discharge assembly 34 smoothly transports the sealed finished product out of the M-bag packaging machine, achieving automation and high efficiency throughout the entire packaging process.
[0036] The practical operation is as follows: When the M-bag packaging machine is working, the conveying device 21 of the M-bag loading device 2 transports the M-bag to the opening component 22, which opens the bag opening. At this time, the flipping bag-picking device 23 rises under the drive of the lifting bag-picking component, picks up the bag through the bag-clamping component, and then flips it under the action of the servo flipping component, placing the bag on the bag positioning device 24. The bag storage component 25 can lift the spare bag for easy picking by the bag-picking robot 26; the lifting drive source 42 of the detection mechanism 4 drives the detection base 43 to descend, so that the detection arm 44 inserts into the opening end of the M-bag loading device 2. If the detection arm 44 contacts the packaging bag, the detection sensor 45 senses the change in the swing of the detection arm 44 and determines that a packaging bag is present. The detection mechanism 4 feeds the information back to the control system, and at the same time, transports the M-bag loading device 2 with the packaging bag to the empty position of the bag-supporting mechanism 5. The second lifting drive source 52 of the bag-supporting mechanism 5 drives the bag-supporting seat 53 to descend, so that the front and rear bag-supporting components 54 and the left and right bag-supporting components 55 are inserted into the M-bag. Then, the servo motor drives the front and rear support bars to move away from each other, and the second servo motor drives the bag-supporting arms to move away from each other, thereby opening the M-bag to all sides. The rounded corner transition design of the fixture block at the end of the bag-supporting arm can effectively avoid damage to the packaging bag. The opened M-bag is transported to the finished product packaging device 3, and the material feeding device 31 introduces the raw material into the packaging bag. Next, the vacuum device 32 rises to perform a vacuum operation on the packaging bag, and then the sealing device 33 seals the packaging bag. Finally, the discharge component 34 rises to transport the sealed finished product out of the M-bag packaging machine. Through the coordinated operation of the above-mentioned devices, the M-bag packaging machine of the present invention can efficiently and stably complete the packaging of M-bags, improving the quality and efficiency of packaging and showing good application prospects.
