Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, specifically to a high-speed, fully automatic, intelligent packaging device. Background Technology

[0002] Pre-packed liquid packaging machines are core equipment for the automated packaging of bagged liquid products. They rely on a heat-sealing mechanism to fused and sealed the opening of the filled packaging bag at high temperature, thereby isolating the liquid inside the bag and ensuring the sealing of the finished product. During continuous mass production, a common problem occurs where the packaging bag is not properly heat-sealed, leaving tiny gaps at the seal and allowing the liquid inside the bag to continuously leak out.

[0003] Automated production lines often operate continuously for extended periods, making it difficult to have dedicated personnel monitoring and inspecting the entire process. If leaks are not detected and addressed promptly, they can lead to multiple production hazards. Leaking liquids flow unchecked along the equipment frame and worktable, soaking the machine's transmission components, electrical control circuits, sensors, and other related parts. This damages the entire machine and surrounding production equipment, increases maintenance and parts replacement costs, extends downtime for repairs, and disrupts the continuous production rhythm of the assembly line.

[0004] Meanwhile, the equipment's detection and identification mechanisms exhibit lag. Even if a leak occurs at the seal, the front-end feeding mechanism continues to deliver the liquid to be packaged into the empty bag according to the established procedure. The damaged packaging bag cannot retain material, and all the delivered liquid continues to leak out, causing significant waste of raw materials and directly increasing the production cost of the product. Furthermore, the leak spreads as the equipment operates, gradually escalating from a simple sealing defect into a large-scale material leakage problem, exacerbating liquid waste and equipment corrosion. The flowing liquid, mixed with packaging bag debris and stains, covers the production surface, worsening the workshop working environment and causing numerous problems for on-site management. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high-speed, fully automatic intelligent packaging device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed fully automatic intelligent packaging device, comprising a base, a housing mounted on the upper surface of the base, an inclined liquid storage tank mounted on the upper surface of the housing, a drain pipe connected to the bottom of the liquid storage tank via a solenoid valve, the drain pipe extending to one side of the housing, a sliding trough for sliding the packaged plastic bag along a designated path directly below the drain pipe, the sliding trough having a U-shaped cross-section, the sliding trough being inclinedly installed at the lower part of one side of the housing, a drain outlet being provided at the lower part of the sliding trough, the drain outlet being arranged along the width direction of the sliding trough, a housing being provided below the drain outlet, a detachable bottom cover being installed at the lower end of the housing, a cutting element being installed in the space formed by the bottom cover and the housing, the cutting element disconnecting the solenoid valve circuit and closing the solenoid valve when leakage occurs in the plastic bag. After the finished packaging bags are filled, they are conveyed directionally along the inclined material chute. If the bag opening is not sealed properly and leakage occurs, the leaked liquid will be collected at the drain outlet and drip into the lower housing. After the cut-off part detects the leakage, it can directly cut off the control circuit of the solenoid valve at the bottom of the liquid storage tank. The solenoid valve will immediately close and stop the material supply. The faulty station will immediately stop the liquid filling and will not continue to deliver material to the damaged empty bag, reducing raw material leakage and loss. It also prevents liquid corrosion and short circuit faults, reduces the frequency of equipment maintenance and downtime, and ensures continuous high-speed operation of the production line.

[0007] Specifically, the cutting component includes a limit switch. A limit switch is installed on the side of the housing away from the drain port to disconnect the solenoid valve circuit and close the solenoid valve when leakage occurs in the plastic packaging bag. A sliding plate is connected to the upper surface of the bottom cover near the limit switch via a guide assembly. A pressing part for squeezing the contact part of the limit switch is installed at one end of the sliding plate. A piece of paper is glued to the upper surface of the sliding plate away from the pressing part. The end of the paper away from the sliding plate is glued to the housing. The paper is positioned directly below the drain port. The sliding plate and the paper are both arranged along the inclined direction of the material groove. During normal production, the paper sheet is bonded to the connecting parts and the slide plate at both ends. The tension of the paper sheet keeps the slide plate in a position away from the limit switch, and the limit switch remains on, allowing the solenoid valve to feed normally. Once leakage occurs, the paper sheet drips from the drain port and soaks the paper sheet. After absorbing water, the paper sheet's strength decreases rapidly and it breaks automatically. The tension of the paper sheet on the slide plate disappears, and the slide plate slides along the inclined guide structure to one side of the travel limit. The holding part squeezes the limit switch contact, directly cutting off the power supply circuit of the solenoid valve and instantly stopping the filling and feeding. The purely mechanical induction structure is not affected by the conductivity, impurities, or viscosity of the liquid. It can stably detect acidic, alkaline, and high-salt liquids without the risk of short circuits caused by soaking electronic components. The paper sheet is a disposable, low-cost consumable that is easy to replace, reducing equipment maintenance costs. The entire triggering mechanism is arranged along the inclined direction of the sliding material, matching the direction of the leaking liquid. The liquid can completely wet the paper sheet, resulting in high leakage detection sensitivity. Even a small amount of leakage can quickly trigger a shutdown and material cutoff, preventing small leaks from escalating into large-scale material leakage problems.

[0008] Specifically, the guiding assembly includes guide rails. Two guide rails are symmetrically installed on the lower surface of the slide plate. The guide rails are arranged along the inclined direction of the material channel. A T-slot is formed on the side of the guide rail facing the limit switch, extending along the length of the guide rail. The end of the T-slot away from the limit switch is closed. Two T-strips are installed on the upper surface of the bottom cover. The upper ends of the T-strips are slidably installed within the T-slots. When the paper does not break, the T-strips are positioned within the T-slots closer to the limit switch. Two guide rails are symmetrically arranged at the bottom of the slide plate, with T-slots. The T-strips fixed to the bottom cover are embedded in the T-slots to form a locking sliding pair, allowing the slide plate to slide unidirectionally towards the limit switch along an inclined straight line without lateral deviation, flipping, or jamming. The symmetrical arrangement of the two guide rails ensures balanced force on the slide plate, resulting in smooth and uninterrupted movement.

[0009] Specifically, a strip-shaped opening is provided on the lower surface of the bottom cover near the limit switch. A liquid collection hood is provided below the strip-shaped opening, and a bent pipe for connecting the drain pipe is installed at the bottom of the liquid collection hood. The leaking liquid collected inside the housing flows through the strip-shaped opening into the liquid collection hood. The bent pipe can be connected to an external guide hose to directionally transport the leaking liquid to a recovery tank for secondary filtration and reuse, reducing material loss. The strip-shaped opening is continuous in width, allowing liquid to flow out smoothly from all parts of the housing, preventing accumulation and stagnation inside the housing and bottom cover, and avoiding long-term soaking of the limit switch, slide plate, etc. by waste liquid.

[0010] Specifically, the bottom cover has a connecting edge on its upper side. The connecting edge is rectangular in shape and is fitted onto the lower end of the housing and fixed to it. The connecting edge is connected to the bottom cover by fasteners formed by multiple sets of bolts and nuts. A sealing gasket is provided between the connecting edge and the bottom cover to prevent bolts from passing through the sealing gasket and thus limiting their relative position. The rectangular connecting edge is fitted onto the lower end of the housing, and a sealing gasket is installed between the connecting edge and the bottom cover. After the bolts are tightened, the sealing gasket completely fills the assembly gap, preventing any leakage from the housing from spilling out through the joint. The use of multiple sets of detachable bolts and nuts for fastening allows for easy maintenance and replacement of paper sheets or cleaning of accumulated dirt inside the housing; simply removing the fasteners is sufficient to separate the bottom cover.

[0011] Specifically, a support plate is provided on the side of the housing away from the chassis. The support plate has a "C"-shaped structure. The upper horizontal section of the support plate is connected to the connecting edge by fasteners formed by bolts and nuts, and the lower horizontal section of the support plate is connected to the base. The support plate improves the stability of the material chute installation.

[0012] Specifically, the end of the paper sheet away from the slide plate is glued with a connecting part. This connecting part is installed inside the housing on the side away from the limit switch, and is arranged along the inclined direction of the slide groove. The connecting part facilitates the bonding of one end of the paper sheet to the inner wall of the housing.

[0013] Specifically, the upper end of the liquid storage tank is bolted to a tank cover, and a liquid filling hopper is installed on the upper surface of the tank cover. The liquid filling hopper communicates with the internal space of the liquid storage tank, and a positioning seat for restricting the position of the liquid storage tank is installed on the upper surface of the tank cover. By installing the positioning seat at the desired position, the position of the liquid storage tank is restricted.

[0014] Specifically, a plastic bag storage shaft is provided on one side of the liquid storage tank. The plastic bag storage shaft is arranged horizontally and is connected to the machine housing via a guide frame. Both the guide frame and the plastic bag storage shaft are located on the upper side of the material chute. The horizontal arrangement of the plastic bag storage shaft ensures smooth rotation of the roll material without jamming. The guide frame restricts the lateral deviation of the roll material, resulting in a flat and wrinkle-free bag during the bag removal process. This enhances the stability of the bag opening and filling processes and ensures high-speed continuous operation of the production line.

[0015] Specifically, the base has a rectangular structure, and four brake casters are installed on the lower surface of the base. The four brake casters are evenly distributed at the four corners of the base bottom. The brake casters at the four corners of the base give the whole machine flexible movement and fixed-point locking functions, making it suitable for multi-workshop rotation production, workstation adjustment, and equipment cleaning scenarios.

[0016] The beneficial effects of this invention are:

[0017] When there is no leakage during normal packaging, the paper remains intact, the slide plate stays away from the limit switch, the solenoid valve at the bottom of the liquid storage tank remains open, and the filling process runs normally. When the packaging bag is not sealed tightly and leakage occurs, the leaked liquid drips through the drain port on the slide trough and soaks the paper. The paper breaks upon contact with the liquid, and the slide plate slides along the guide rail toward the limit switch. The holding part touches the contact of the limit switch and cuts off the solenoid valve control circuit. The solenoid valve then closes and stops feeding. This allows the liquid supply to be stopped immediately after a leakage fault occurs, and the damaged packaging bag no longer receives liquid material, preventing unlimited liquid leakage, reducing raw material loss, and avoiding a single sealing defect from developing into a large-scale leakage fault.

[0018] After leaking liquid passes through the shell, it falls into the collection hood through the strip-shaped opening, and then is uniformly discharged to the designated recovery container through the drainage pipe connected to the bottom bend. The liquid is contained in a closed system throughout the process, preventing it from wetting the machine body's electrical control circuits, transmission components, and sensing elements. This prevents liquid from corroding metal parts, causing short circuits and damaging the equipment, reducing equipment maintenance and parts replacement costs, and ensuring the long-term stable operation of the production line.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Please see Figures 1-9 The present invention provides a technical solution: a high-speed fully automatic intelligent packaging device, including a base 100, the base 100 having a rectangular structure, and four brake casters 104 mounted on the lower surface of the base 100. The four brake casters 104 are evenly arranged at the four corners of the bottom of the base 100. The installation of brake casters 104 on the base 100 facilitates the movement of the position of the base 100.

[0036] A chassis 101 is mounted on the upper surface of the base 100. An inclined liquid storage tank 102 is mounted on the upper surface of the chassis 101. A drain pipe 1021 is connected to the bottom of the liquid storage tank 102 via a solenoid valve. The drain pipe 1021 extends to one side of the chassis 101. A tank cover 1023 is bolted to the upper end of the liquid storage tank 102. A liquid filling hopper 1022 is mounted on the upper surface of the tank cover 1023. The liquid filling hopper 1022 communicates with the internal space of the liquid storage tank 102. A positioning seat 1024 is mounted on the upper surface of the tank cover 1023 to limit the position of the liquid storage tank 102, so that the positioning seat 1024 is installed in the required position, thereby limiting the position of the liquid storage tank 102.

[0037] A plastic bag storage shaft 103 is provided on one side of the liquid storage tank 102. The plastic bag storage shaft 103 is arranged horizontally and is connected to the machine housing 101 through a guide frame 1031. The guide frame 1031 and the plastic bag storage shaft 103 are both set on the upper side of the material chute 200. The base 100, machine housing 101, etc., form the skeleton structure of the bag-type liquid packaging machine. The bag-type liquid packaging machine is a multi-station intermittent rotary automated equipment that relies on a precision divider to drive the turntable to cyclically index, and each station operates synchronously and in parallel. The entire process of bag picking, coding, bag opening detection, quantitative liquid filling, bag mouth cleaning, venting, multi-stage heat sealing, cooling, and material unloading is completed sequentially. The whole set of actions is coordinated by PLC, servo motor, and pneumatic components. It realizes fully automatic quantitative sealing packaging of fluid materials such as aqueous solutions and liquid fertilizers. The working principle of bag picking, coding, bag opening detection, quantitative liquid filling, bag mouth cleaning, venting, multi-stage heat sealing, cooling, and material unloading of the bag-type liquid packaging machine has been fully disclosed in the existing technology, so it will not be described in detail here.

[0038] Below the drain pipe 1021 is a sliding chute 200 for sliding the packaged plastic bag along a designated path. The sliding chute 200 has a U-shaped cross-section and is installed at an angle on the lower part of one side of the casing 101. A drain port 201 is provided at the lower part of the sliding chute 200, and the drain port 201 is arranged along the width direction of the sliding chute 200. A housing 300 is provided below the drain port 201, and a connecting edge 303 is provided on the upper side of the bottom cover 301. The connecting edge 303 has a rectangular structure and is fitted onto the lower end of the housing 300 and connected and fixed to the housing 300, so that the connecting edge 303 can pass through... Multiple sets of bolts and nuts form fasteners that are connected to the bottom cover 301, enabling the installation of a detachable bottom cover 301 at the lower end of the housing 300. A sealing washer 308 is provided between the connecting edge 303 and the bottom cover 301. The bolts that restrict the relative position of the connecting edge 303 and the bottom cover 301 pass through the sealing washer 308. After the bolts are tightened, the sealing washer 308 completely fills the assembly gap, preventing liquid leakage from the housing 300 from overflowing from the splicing seam. The use of multiple sets of bolts and nuts for detachable fastening facilitates the maintenance and replacement of the paper sheet 304 and the cleaning of accumulated dirt inside the housing 300.

[0039] A support plate 400 is provided on the side of the housing 300 away from the chassis 101. The support plate 400 has a "C" shaped structure. The upper horizontal section of the support plate 400 is connected to the connecting edge 303 by fasteners formed by bolts and nuts. The lower horizontal section of the support plate 400 is connected to the base 100. The support plate 400 and the chassis 101 together support the material slide 200 and improve the stability of the structure.

[0040] Inside the housing 300, on the side away from the drain port 201, is a limit switch 306 that disconnects the solenoid valve circuit and closes the solenoid valve when leakage occurs in the plastic packaging bag. Two guide rails 3010 are symmetrically mounted on the lower surface of the slide plate 305. The guide rails 3010 are arranged along the inclined direction of the sliding groove 200. A T-slot 30101, arranged along the length of the guide rail 3010, is formed on the side of the guide rail 3010 facing the limit switch 306. The end of the T-slot 30101 away from the limit switch 306 is closed. Two T-shaped strips 309 are mounted on the upper surface of the bottom cover 301. The upper end of the T-shaped strip 309 is slidably installed in the T-shaped groove 30101. When the paper 304 is not broken, the T-shaped strip 309 is located in the T-shaped groove 30101 on the side close to the limit switch 306. The guide rail 3010 has a T-shaped groove 30101. The T-shaped strip 309 fixed by the bottom cover 301 is embedded in the T-shaped groove 30101 to form a locking sliding pair. The slide plate 305 is only allowed to slide unidirectionally towards the limit switch 306 along the inclined straight line. It will not shift left or right, flip or jam throughout the entire process. The double guide rails 3010 are symmetrically arranged, and the sliding force of the slide plate 305 is balanced, so the movement is smooth and without jamming.

[0041] A sliding plate 305 is connected to the upper surface of the bottom cover 301 near the limit switch 306 via a guide assembly. One end of the sliding plate 305 is fitted with a pressing part 3051 for pressing the contact portion of the limit switch 306. A piece of paper 304 is glued to the upper surface of the sliding plate 305 away from the pressing part 3051. A connecting part 3041 is glued to the end of the paper 304 away from the sliding plate 305. The connecting part 3041 is installed inside the housing 300 on the side away from the limit switch 306. The connecting part 3041 is arranged along the inclined direction of the sliding groove 200. The paper 304 is positioned directly below the drain port 201. Both the sliding plate 305 and the paper 304 are arranged along the inclined direction of the sliding groove 200. Under normal packaging conditions without leakage, the paper 304 remains intact, and the sliding plate 305 remains in a position away from the limit switch 306. The solenoid valve at the bottom of the liquid storage tank 102 remains open, ensuring normal operation of the filling process. When leakage occurs due to improper sealing of the packaging bag, the leaked liquid drips through the drain port 201 on the sliding trough 200 and soaks the paper sheet 304. The paper sheet 304 breaks upon contact with the liquid, and the slide plate 305 slides along the guide rail 3010 toward the limit switch 306. The holding part 3051 touches the contact part of the limit switch 306 and cuts off the solenoid valve control circuit. The solenoid valve then closes and stops feeding, thus immediately terminating the liquid supply after a leakage fault occurs. The damaged packaging bag no longer receives liquid material, preventing unlimited liquid leakage, reducing raw material loss, and avoiding a single sealing defect from developing into a large-scale leakage fault. It eliminates the need for staff to monitor the feeding and discharging area in real time, reducing the frequency of inspections, saving workshop labor management costs, and is suitable for long-term uninterrupted automated mass production operations.

[0042] A strip-shaped opening 307 is provided on the lower surface of the bottom cover 301 near the limit switch 306. A liquid collection hood 302 is provided below the strip-shaped opening 307. A bent pipe 3021 for connecting the drain pipe is installed at the bottom of the liquid collection hood 302. After leaking liquid passes through the housing 300, it falls into the liquid collection hood 302 through the strip-shaped opening 307. Then, it is uniformly discharged to the designated recovery container through the drain pipe connected to the bottom bent pipe 3021. The liquid is contained in a closed system throughout the process, and will not wet the machine body's electrical control circuit, transmission components and sensing elements. This prevents liquid from corroding metal parts, causing short circuits and damaging the equipment, reducing equipment maintenance and parts replacement costs, and ensuring the long-term stable operation of the production line.

[0043] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
