Description

Technical Field

[0001] This utility model relates to the field of ton bag unpacking machine technology, and in particular to a dual-station suction gun structure for a fully automatic ton bag unpacking machine. Background Technology

[0002] In industries such as pharmaceuticals, food, and chemicals that involve powders or granular materials, fully automatic ton bag unpacking machines are key equipment for achieving efficient and dust-free unloading. Currently, mainstream fully automatic ton bag unpacking machines on the market typically have only one fixed suction station on their frame 1, equipped with a fixed suction gun 2. This single-station design reveals significant limitations in actual operation: after unpacking one type of material, if switching to another material is required, a thorough shutdown and cleaning of the fixed suction gun 2, its connected first negative pressure pipe 21, first adsorption pipe 22, and even the entire conveying pipeline system is necessary. This process is cumbersome, time-consuming, and seriously affects the equipment's production efficiency and continuity. More importantly, if cleaning is not thorough, residual material can easily lead to cross-contamination between different batches or types of products, posing a serious risk to product quality and safety.

[0003] To address the need for handling multiple materials, the existing solution is to purchase multiple ton bag unpacking machines to achieve physical isolation. While this method avoids contamination, it significantly increases the user's equipment purchase costs, floor space requirements, and subsequent maintenance burden, resulting in extremely poor economic efficiency and space utilization.

[0004] Therefore, there is an urgent need in this field for a suction gun structure that can achieve rapid and isolated material switching on a single ton bag unpacking machine, in order to solve cleaning problems, eliminate the risk of contamination and reduce overall costs. Utility Model Content

[0005] The purpose of this invention is to provide a suction gun structure that enables rapid and isolated material switching on a single ton bag unpacking machine, thereby solving cleaning problems, eliminating the risk of contamination, and reducing overall costs.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dual-station suction gun structure for a fully automatic ton bag unpacking machine, comprising a frame, on which a first slide rail and a second slide rail are symmetrically mounted; a first movable suction gun and a second movable suction gun, which operate independently and are connected by connecting parts, are slidably connected on the first slide rail and the second slide rail; a first L-shaped connecting part and a second L-shaped connecting part are respectively provided on both sides of the first movable suction gun, and the first L-shaped connecting part and the second L-shaped connecting part are slidably connected to the first slide rail and the second slide rail respectively; a third L-shaped connecting part and a fourth L-shaped connecting part are respectively provided on both sides of the second movable suction gun. The first slide rail and the second slide rail are slidably connected to the third L-shaped connector and the fourth L-shaped connector, respectively. A cylinder is provided on one side of the first slide rail or the second slide rail. The cylinder includes a fixed end and a telescopic end. The fixed end is mounted on the frame, and the telescopic end is connected to the first or second movable suction gun. The first movable suction gun is connected to a second negative pressure pipe and a second suction pipe, and the second movable suction gun is connected to a third negative pressure pipe and a third suction pipe. The telescopic movement of the cylinder drives the first and second movable suction guns to move synchronously along the slide rail, so that the first or second movable suction gun is sent to the designated suction station A for operation.

[0007] Preferably, the frame is provided with a first frame and a second frame; the first slide rail and the second slide rail are respectively provided on the first frame and the second frame.

[0008] Preferably, the first slide rail and the second slide rail are respectively provided with a first slider and a second slider, the first L-shaped connector and the second L-shaped connector are respectively connected to the first slider and the second slider, and the third L-shaped connector and the fourth L-shaped connector are also respectively connected to the first slider and the second slider.

[0009] Preferably, the first movable suction gun and the second movable suction gun have the same structure, both including a negative pressure tube and an adsorption tube.

[0010] Preferably, the telescopic end of the cylinder is connected to the second movable suction gun via a movable end connector.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention uses a cylinder to drive the first and second mobile suction guns to slide on a slide rail, alternately entering the same suction station A. When one material has been suctioned and it is necessary to switch to another material, there is no need to stop the machine for cleaning; simply switching the suction guns is achieved by the cylinder. The two sets of suction guns and their matching negative pressure pipes and adsorption pipes are completely independent, physically isolating the contact paths of different materials, eliminating the risk of cross-contamination, and greatly improving work efficiency; achieving efficient and pollution-free multi-material switching.

[0012] This structure upgrades a single-station to a dual-station machine simply by adding a set of slide rails (first and second slide rails) and a cylinder 5 to the crossbeam of the existing ton bag unpacking machine. The overall structure is simple and compact, requiring no additional unpacking machine while achieving a significant increase in functionality. This eliminates the need for users to invest heavily in multiple machines to handle various materials, greatly reducing equipment costs and space requirements. The compact structure offers low modification costs and wide applicability.

[0013] The symmetrical arrangement of slide rails and sliders ensures smooth movement and accurate positioning of the mobile suction gun during switching. Powered by a cylinder, it offers rapid response and simple control. Attached Figure Description

[0015] Figure 1In the existing design described in the background art, where a fixed suction gun 2 is mounted on a frame 1, after unpacking one type of material, if it is necessary to switch to another material, a thorough shutdown and cleaning of the fixed suction gun 2, its connected first negative pressure pipe 21, first suction pipe 22, and even the entire conveying pipeline system is required. Incomplete cleaning can easily lead to cross-contamination of materials, and the cleaning process reduces production efficiency.

[0016] To address the problems in the background technology, this utility model provides a dual-station suction gun structure for a fully automatic ton bag unpacking machine, including a frame 1. A first slide rail 6 and a second slide rail 7 are symmetrically installed on the crossbeam of the frame 1. A first movable suction gun 3 and a second movable suction gun 4 that work independently are slidably connected on the first slide rail 6 and the second slide rail 7. The first movable suction gun 3 and the second movable suction gun 4 are linked by a first slider 61 and a second slider 71 on the first slide rail 6 and the second slide rail 7, ensuring that the two move synchronously under the drive of the cylinder 5. The first movable suction gun 3 and the second movable suction gun 4 have the same structure and function, but are independent of each other and are used to suck up different materials. Their corresponding negative pressure pipelines and adsorption pipelines are also independent of each other. The first movable suction gun 3 is connected to a first L-shaped connector 33 and a second L-shaped connector 34, which are slidably connected to the first slide rail 6 and the second slide rail 7, respectively. The second movable suction gun 4 is connected to a third L-shaped connector 43 and a fourth L-shaped connector 44, which are slidably connected to the first slide rail 6 and the second slide rail 7, respectively. Specifically, the first slide rail 6 and the second slide rail 7 are respectively provided with a first slider 61 and a second slider 71. The first L-shaped connector 33 and the second L-shaped connector 34 are respectively connected to the first slider 61 and the second slider 71, and the third L-shaped connector 43 and the fourth L-shaped connector 44 are also respectively connected to the first slider 61 and the second slider 71. A cylinder 5 is provided on one side of the first slide rail 6 or the second slide rail 7. The cylinder 5 includes a fixed end 51 and a telescopic end 52. The fixed end 51 is mounted on the frame 1 by a fixing member 53. The telescopic end 52 is connected to the first movable suction gun 3 or the second movable suction gun 4. The first movable suction gun 3 is connected to the second negative pressure pipe 31 and the second suction pipe 32. The second movable suction gun 4 is connected to the third negative pressure pipe 41 and the third suction pipe 42. The telescopic movement of the cylinder 5 drives the first movable suction gun 3 and the second movable suction gun 4 to move synchronously along the slide rail, so that the first movable suction gun 3 or the second movable suction gun 4 is sent to the designated suction station A for operation.

[0017] Reference Figure 2 , Figure 3 , Figure 4In this system, the power is provided by cylinder 5, which extends in the X direction, i.e., the length direction of frame 1; the width direction of frame 1 is the Y direction, and the vertical upward direction is the Z direction. A first slide rail 6 and a second slide rail 7 are installed on the top crossbeam of frame 1. Specifically, the first slide rail 6 and the second slide rail 7 are symmetrically installed on the first frame 11 and the second frame 12 at the top of frame 1. Both the first frame 11 and the second frame 12 are rectangular frames along the X direction, and multiple supporting ribs 14 are provided inside the rectangular frames in the Y direction. These supporting ribs 14 are welded or fixedly connected between the edges of the first frame 11 and the second frame 12, forming a reinforcing rib structure to increase the strength of the first frame 11 and the second frame 12. The space between the first frame 11 and the second frame 12 forms a blank area 15, which provides an unobstructed movement channel for the first movable suction gun 3 and the second movable suction gun 4, allowing them to slide freely within this space and achieve alternating switching of workstations. The middle position of the blank area 15 in the X direction is the suction station A. The first slide rail 6 and the second slide rail 7 are parallel to each other, and a first slider 61 and a second slider 71 are slidably mounted on top of each other. The lengths of the first slider 61 and the second slider 71 are less than the lengths of the first slide rail 6 and the second slide rail 7, respectively, to ensure that the movement distance of the first slider 61 and the second slider 7 on the first slide rail 6 and the second slide rail 7 can meet the displacement requirements of the suction gun switching. A first movable suction gun 3 and a second movable suction gun 4 are installed. The first L-shaped connector 33 and the second L-shaped connector 34 of the first movable suction gun 3 are connected to the first slider 61 and the second slider 71 on the first slide rail 6 and the second slide rail 7, respectively. Similarly, the third L-shaped connector 43 and the fourth L-shaped connector 44 on the second movable suction gun 4 are also connected to the first slider 61 and the second slider 71 on the first slide rail 6 and the second slide rail 7, respectively. The slide rail and slider configuration effectively ensures the stability and rigidity of the movable suction gun during movement. The fixed end 51 of the cylinder 5 is fixed to the frame 1 by a mounting base. The cylinder 5 can be located on one side of the first slide rail 6 or the second slide rail 7. Figure 3 The cylinder 5 shown is located on one side of the second slide rail 7. The telescopic end 52 of the cylinder 5 is connected to the second movable suction gun 4 (e.g., via a movable end connector 54) through a movable end connector 54. Figure 5 , Figure 6 (As shown). Therefore, when cylinder 5 is activated, it will directly drive the second movable suction gun 4 to move. Since both the first movable suction gun 3 and the second movable suction gun 4 are mounted on the same slider, when cylinder 5 pushes the second movable suction gun 4, it will synchronously drive the first movable suction gun 3 to move in the same direction.

[0018] The first movable suction gun 3 and the second movable suction gun 4, compared to the fixed suction gun 2, have a movable slider; otherwise, their structures are the same as those of the fixed suction gun 2 in the prior art. The first movable suction gun 3 is connected to an independent second negative pressure pipe 31 and a second suction pipe 32; the second movable suction gun 4 is connected to an independent third negative pressure pipe 41 and a third suction pipe 42. These pipes are all flexible hoses or metal flexible hoses with sufficient slack to accommodate the movement of the suction guns and ensure no interference with the frame or other components. All piping systems are independent of each other, physically isolating the flow paths of different materials.

[0019] During use, the first material absorption state: see [link / reference] Figure 2 and Figure 3 At this time, the telescopic end 52 of cylinder 5 is in the retracted state. In this state, the second movable suction gun 4 is positioned at the designated suction station A (usually located in the center area of ​​the frame). The third negative pressure pipe 41 is connected to the negative pressure source, and the second movable suction gun 4 begins to work, sucking up the first type of material through the third suction pipe 42. At the same time, the first movable suction gun 3 is in a standby position on the left side of station A. When the suction of the first type of material is completed and it is necessary to switch to the second type of material, the telescopic end 52 of cylinder 5 extends; through the movable end connector 54, cylinder 5 directly pushes the second movable suction gun 4 to slide along the first slide rail 6 and the second slide rail 7 away from the suction station A. Since the second movable suction gun 4 is connected to the first movable suction gun 3, as the second movable suction gun 4 moves to the right side of station A, it will simultaneously pull the first movable suction gun 3 to station A; at this time, the second negative pressure pipe 31 is connected, and the first movable suction gun 3 begins to suck up the second type of material through the second suction pipe 32. The second movable suction gun 4 is then in a standby state on the right side of the suction station A.

[0020] This invention provides a dual-station suction gun structure for a fully automatic ton bag unpacking machine. A first slide rail 6 and a second slide rail 7 are symmetrically installed on the crossbeam of the frame 1, and a first movable suction gun 3 and a second movable suction gun 4, which can slide synchronously along the slide rails, are configured. A cylinder 5 acts as the actuator, pushing the first movable suction gun 3 and the second movable suction gun 4 alternately into the same suction station A. When the first type of material needs to be suctioned, the telescopic end 52 of the cylinder 5 extends, positioning the first movable suction gun 3 at station A and initiating its operation. When switching to the second type of material, the telescopic end 52 of the cylinder 5 retracts, pushing the first movable suction gun 3 away from station A, while simultaneously pulling the second movable suction gun 4 back to station A for suction. This invention successfully solves the problems of prior art, such as the need for cleaning when switching materials, easy cross-contamination, and high overall equipment cost due to handling multiple materials. The design, using guide rails, sliders, and cylinders, achieves the switching of two independent movable suction guns, making it particularly suitable for automated production scenarios requiring frequent changes in material types.
