Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically to a sealing device for producing laundry detergent packaging bags. Background Technology

[0002] Laundry detergent packaging bags are bags used to package laundry detergent, making it convenient to transport and store during the production and distribution process. Currently, during the processing of packaging bags, it is necessary to seal the edges of the bags to facilitate subsequent bagging.

[0003] For example, the sealing device for packaging bags used in feed production disclosed in authorization announcement number CN220315504U includes a sealing machine, a sealing strip driven at one end of the sealing machine, and a sliding rod slidably connected in the same sliding grooves on both sides. An elastic sheet is fixedly installed on the side of the sliding rod facing the sealing strip. The beneficial effects of this utility model after adopting the above technical solution are: it solves the technical problem that the difference in position between the feed packaging bag and the sealing strip of the sealing machine leads to feed leakage and contamination, and increases the scrap rate of the packaging bag.

[0004] Although the aforementioned patent includes a support plate for lifting and placing the feed-filled packaging bags before sealing, the horizontal lifting of the support plate causes the feed to leak out of the bag opening after the feed-filled packaging bags are placed, thus affecting the subsequent sealing operation. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device for the production of laundry detergent packaging bags, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sealing device for producing laundry detergent packaging bags, comprising: The workbench has a ramp fixedly connected to its front, and a clamping mechanism is provided on the side of the ramp away from the workbench. A frame is fixedly connected to the side of the workbench away from the inclined platform, and an edge sealing mechanism is provided on the frame; The dovetail guide rails are symmetrically and fixedly connected to the outside of both sides of the worktable, and a pressing mechanism is provided between the two dovetail guide rails.

[0007] Preferably, the clamping mechanism includes a fixed base 1 fixedly connected to the middle of the top back of the inclined platform away from the worktable, an electric push rod 3 fixedly connected to the top of the fixed base 1, a drive plate fixedly connected to the output shaft of the electric push rod 3, a clamping plate provided on the side of the inclined platform away from the fixed base 1, the clamping plate being fixedly connected to the drive plate, and a sliding groove for sliding cooperation with the drive plate being provided in the middle of the inclined platform. Preferably, the edge sealing mechanism includes an electric push rod fixedly connected to the middle of the top of the frame, and a hot press plate disposed below the front of the frame. The output shaft of the electric push rod is fixedly connected to the middle of the top of the hot press plate. Vertical guide rods are fixedly connected to both sides of the top of the hot press plate. Guide holes that are slidably connected to the guide rods are opened through both sides of the top of the frame. Preferably, the pressing mechanism includes a dovetail slider slidably connected to the outside of the dovetail guide rail, and a fixed seat two fixedly connected to the outside of the rear end of the dovetail guide rail. An electric push rod four is fixedly connected to the back of the fixed seat two, and the output shaft of the electric push rod four is fixedly connected to the dovetail slider. Preferably, the pressing mechanism further includes a bracket fixedly connected to the top of the dovetail slider, and a roller frame set at the top of the two dovetail guide rails. A clamping rod is rotatably connected between the two roller frames through a bearing. An electric push rod II is fixedly connected to the top of the bracket, and the output shaft of the electric push rod II is fixedly connected to the roller frame. Preferably, the upper surface of the worktable makes rolling contact with the outer periphery of the clamping roller.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This sealing device for producing laundry detergent packaging bags uses a combination of an inclined platform and a clamping mechanism to allow the material inside the bag to collect at the bottom of the bag under gravity. The clamping plate then firmly holds the tail of the packaging bag, ensuring that there is no material accumulation at the bag opening and that the bag is in a naturally taut state. This effectively solves the problem of loose bag openings and easy leakage of material from the bag opening caused by horizontal lifting, which affects the sealing operation.

[0009] This sealing device for producing laundry detergent packaging bags uses the combined pressing and retracting action of the clamping rollers in the pressing mechanism to flatten and press the bag opening area against the worktable before heat sealing, ensuring the flatness of the bag opening before sealing. This effectively solves technical problems such as poor sealing and leakage caused by bag opening wrinkles, and improves sealing quality and yield. Attached Figure Description

[0012] 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.

[0013] like Figure 1-4 As shown, this utility model provides a technical solution: A sealing device for producing laundry detergent packaging bags includes a workbench 1 with an inclined platform 2 fixedly connected to its front. A clamping mechanism is provided on the side of the inclined platform 2 away from the workbench 1. The clamping mechanism includes a fixed base 5 fixedly connected to the middle of the top of the back side of the inclined platform 2 away from the workbench 1. An electric push rod 6 is fixedly connected to the top of the fixed base 5. The output shaft of the electric push rod 6 is fixedly connected to a drive plate 7. A clamping plate 8 is provided on the side of the inclined platform 2 away from the fixed base 5. The clamping plate 8 is fixedly connected to the drive plate 7. A sliding groove for sliding cooperation with the drive plate 7 is opened in the middle of the inclined platform 2. A frame 3 is fixedly connected to the side of the workbench 1 away from the inclined platform 2. A sealing mechanism is provided on the frame 3. The sealing mechanism includes an electric push rod 9 fixedly connected to the middle of the top of the frame 3, and a hot press plate 10 located below the front of the frame 3. The output shaft of the electric push rod 9 is fixedly connected to the middle of the top of the hot press plate 10. Both sides of the top of the hot press plate 10 are fixedly connected to... The machine frame 3 has a vertical guide rod 11, and guide holes 12 are slidably connected to the guide rod 11 on both sides of the top of the frame 3. The dovetail guide rails 4 are symmetrically fixed to the outside of both sides of the worktable 1. A pressing mechanism is set between the two dovetail guide rails 4. The pressing mechanism includes a dovetail slider 13 slidably connected to the outside of the dovetail guide rail 4, and a fixed seat 14 fixedly connected to the outside of the rear end of the dovetail guide rail 4. An electric push rod 15 is fixedly connected to the back of the fixed seat 14. The output shaft of the electric push rod 15 is fixedly connected to the dovetail slider 13. The pressing mechanism also includes a bracket 16 fixedly connected to the top of the dovetail slider 13, and a roller frame 17 set at the top of the two dovetail guide rails 4. A clamping rod 18 is rotatably connected between the two roller frames 17 through a bearing. An electric push rod 19 is fixedly connected to the top of the bracket 16. The output shaft of the electric push rod 19 is fixedly connected to the roller frame 17. The upper surface of the worktable 1 rolls in contact with the outer periphery of the clamping rod 18. In this embodiment, the material inside the bag is gathered at the bottom of the bag under the action of gravity by the inclined platform 2 and the clamping mechanism. The tail of the packaging bag is firmly clamped by the clamping plate 8, which ensures that there is no material accumulation in the bag opening area and that it is in a natural tension state. This effectively solves the problem of bag opening loosening and material leakage from the bag opening caused by horizontal lifting, which affects the sealing operation.

[0014] Furthermore, by using the combined pressing and retracting action of the clamping roller 18 in the edge pressing mechanism, the bag opening area is first rolled flat and pressed tightly against the workbench 1 before heat sealing, ensuring the flatness of the bag opening before sealing. This effectively solves technical problems such as poor sealing and leakage caused by bag opening wrinkles, and improves the sealing quality and yield.

[0015] Working principle: The operator fixes the tail of the filled laundry detergent bag, which is placed on the inclined platform 2, using a clamping mechanism. During clamping, the electric push rod 6 is activated, extending its output shaft and driving the drive plate 7 and clamping plate 8 downwards. This presses the tail of the bag firmly against the inclined surface of the inclined platform 2. The inclined angle of the platform 2 causes the laundry detergent inside the bag to slide down to the bottom under gravity and be firmly held by the clamping plate 8, ensuring no material accumulation at the bag opening and maintaining a natural tension. Then, the electric push rod 19 is activated, extending its output shaft downwards and pushing the roller frame 17 and clamping roller 18 downwards until the outer circumference of the clamping roller 18 presses the bag opening area against the upper surface of the worktable 1. Next, the electric push rod 15 is controlled to pull the dovetail slider 13 smoothly backwards along the dovetail guide rail 4. The dovetail slider 13, through the bracket 16, electric push rod 19, and roller frame 17, drives the clamping roller 18, which is in a downward-pressed state, forwards. During this process, the clamping roller 18 rolls to completely flatten any wrinkles that may exist at the bag opening, making it completely flat and tightly attached to the workbench 1. Finally, the electric push rod 9 is activated, and its output axis pushes the hot press plate 10 downward. The two guide rods 11 fixed on the hot press plate 10 slide in the guide holes 12 of the frame 3, ensuring that the hot press plate 10 presses down vertically without swaying. The heating module on the lower surface of the hot press plate 10 and the upper surface of the workbench 1 work together to apply a preset temperature and pressure to the fully flattened bag opening and maintain it for a specific time, so that the bag opening is heat-melted and bonded to form a strong sealing edge. After the sealing process is completed, the electric push rod 9 first lifts the hot press plate 10 to reset, and then the electric push rod 15 reverses the action to pull the dovetail slider 13 and the clamping roller 18 forward to reset. Then, the electric push rod 19 lifts the clamping roller 18 away from the bag opening, and finally the electric push rod 6 pushes the clamping plate 8 to release the tail of the packaging bag, and the operator can take out the sealed packaging bag.

[0016] It should be noted that, in the specific implementation of this technical solution, the control components of electric actuator 1 (9), electric actuator 2 (19), electric actuator 3 (6), and electric actuator 4 (15) can be configured with conventional controllers in the prior art (such as PLC programmable controllers, microprocessor control units, or relay logic circuits). Although such controllers are not described in detail in the technical solution, they are standard industrial control components that can be conventionally selected by those skilled in the art based on actual automation sequence control requirements. Their programming logic and electrical connections follow well-known technologies in the field and do not affect the implementation of the core innovation of this solution. In practical applications, this control system is mainly used to coordinate the actions of each electric actuator in a preset sequence (such as clamping, pressing, flattening, heat sealing, and resetting), but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
