Description

Technical Field

[0001] This utility model relates to the field of bagging packaging machine technology, and more specifically to a single-station bagging device. Background Technology

[0002] Existing horizontal bagging machines all use a four-station bag-supporting turntable device to achieve the bagging action. For example, the utility model patent with authorization announcement number CN211167616U, entitled "A Bag-Supporting Device for a Horizontal Bagging Machine," includes a support, a turntable, a turntable drive mechanism, a bag-supporting mechanism, and a bag-supporting drive mechanism. The turntable drive mechanism is mounted on the support, and the turntable is vertically mounted on the drive end of the turntable drive mechanism. Multiple feeding slots are evenly distributed in a ring on the turntable, and a bag-supporting mechanism is installed at each feeding slot. The bag-supporting mechanism includes two... The bag supports consist of two springs; the upper parts of the two bag supports are rotatably connected to both sides of the feed chute; one end of each spring is connected to a turntable, and the other end of each spring is connected to the two bag supports respectively. The two springs drive the two bag supports to move away from each other, causing the bag supports to open the bag opening and hold the inner wall of the bag; the bag support drive mechanism drives the two bag supports to move closer together; a pushing mechanism and a feeding conveyor are installed on one side of the turntable; the pushing mechanism pushes the items on the feeding conveyor from a feed chute into the bags that are opened on the corresponding two bag supports.

[0003] The aforementioned four-station bagging device is only suitable for small-sized packaging bags. It is not suitable for larger bags (e.g., bags over 500mm long, 350mm wide, and 100mm high). This is because, firstly, larger bags require a larger turntable, increasing the overall size of the horizontal bagging machine and necessitating a larger bag-supporting mechanism. Secondly, larger bags require stability rather than efficiency, demanding aesthetically pleasing packaging and a stable packaging process. The four-station bagging device rotates in 90-degree increments, resulting in more frequent stops and increasing the probability of errors. Thirdly, due to the larger bag size, the suspended portion of the bag is prone to deformation during rotation, affecting subsequent material filling and potentially interfering with other components. Utility Model Content

[0004] To overcome the defects and shortcomings of the existing technology, this utility model provides a single-station bagging device. The purpose of this invention is to solve the problem of the inapplicability of existing bagging devices for large-sized packaging bags and the poor stability of the packaging process. This utility model provides a single-station bagging device, including a vertically arranged mounting frame, a mounting plate slidably mounted on the mounting frame, and a drive assembly connected to the mounting plate and driving the mounting plate to slide up and down along the mounting frame. A feeding slot is provided on the mounting plate, and a bag-supporting mechanism is installed at the feeding slot. This utility model uses a single bag-supporting mechanism for up-and-down reciprocating movement to connect the bagging and material filling stations. It is suitable for large-sized packaging bags (such as bags with a length of 500mm, a width of 350mm, and a side height of 100mm or more). After the bag is fitted onto the bag-supporting mechanism, it moves downwards to the filling position, greatly reducing the probability of errors. The single bag-supporting mechanism operates stably, avoiding interference with other components. This utility model has a simple structure and low cost.

[0005] To address the problems existing in the prior art, the present invention is achieved through the following technical solution.

[0006] This utility model provides a single-station bagging device, including a vertically arranged mounting frame, a mounting plate slidably mounted on the mounting frame, and a drive assembly connected to the mounting plate and driving the mounting plate to slide up and down along the mounting frame. A feed groove is provided on the mounting plate, and a bag-supporting mechanism is installed at the feed groove. The bag-supporting mechanism includes a first bag-supporting plate and a second bag-supporting plate. The first bag-supporting plate is rotatably connected to one side of the feed groove, and the second bag-supporting plate is rotatably connected to the other side of the feed groove. The first and second bag-supporting plates are symmetrically arranged. A spring is provided between the first and second bag-supporting plates and the mounting plate. The spring drives the first and second bag-supporting plates to move away from each other, so that the first and second bag-supporting plates open the bag opening and support the inner wall of the bag.

[0007] More preferably, the connection between the first support plate and the mounting plate is rotatably connected and an extension portion is provided outward, and a top block is provided on the extension portion; the connection between the second support plate and the mounting plate is rotatably connected and an extension portion is provided outward, and the extension portion is also provided with a top block.

[0008] More preferably, when the drive assembly drives the bag-supporting mechanism to its highest position, a push rod mechanism is provided on the other side of the mounting plate relative to the bag-supporting mechanism. After the push rod mechanism extends, it acts on the top block of the extension of the first bag-supporting plate and the second bag-supporting plate, causing the first bag-supporting plate and the second bag-supporting plate to move closer to each other around the connection point where they are rotatably connected to the mounting plate.

[0009] More preferably, the push rod mechanism includes a push rod cylinder, a push rod mounting plate, a first push rod, and a second push rod. The push rod mounting plate is mounted on the push rod cylinder. The first push rod and the second push rod are arranged in parallel. One end of each of the first and second push rods is fixedly mounted on the push rod mounting plate. The other ends of the first and second push rods are free ends, which are used to act on the push blocks of the first and second bag support plates respectively when the push rod cylinder is pushed out, so as to drive the first and second bag support plates to move closer to each other around the connection point where they are rotatably connected to the mounting plate.

[0010] More preferably, the push rod mechanism further includes a mounting base, the push rod cylinder is mounted on the mounting base, and the mounting base is mounted on the frame.

[0011] More preferably, the mounting bracket is provided with a pair of parallel slide rails, the slide rails are vertically arranged, and the mounting plate is provided with a slider that cooperates with the slide rails, and the mounting plate slides on the slide rails by means of the slider.

[0012] More preferably, the drive assembly includes a bag-supporting displacement motor assembly, a swing arm, and a connecting rod. One end of the swing arm is fixedly mounted on the output shaft of the bag-supporting displacement motor assembly, one end of the connecting rod is hinged to the other end of the swing arm, and the other end of the connecting rod is hinged to the mounting plate.

[0013] More preferably, the mounting bracket includes a base plate, a first bracket, a second bracket, and a transverse reinforcing plate. The first bracket and the second bracket are mounted parallel and vertically on the base plate. One end of the transverse reinforcing plate is connected to the first bracket, and the other end is connected to the second bracket.

[0014] Even more preferably, a pair of slide rails are fixedly mounted on the first bracket and the second bracket respectively.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. This utility model employs a single bag-supporting mechanism for reciprocating up-and-down movement, connecting the bag-sleeving and material-filling stations. It is suitable for large-sized packaging bags (e.g., bags over 500mm long, 350mm wide, and 100mm high on each side). After the bag is sleeved onto the bag, the bag-supporting mechanism moves downwards to the designated position for material filling, significantly reducing the probability of errors. The single bag-supporting mechanism operates stably, avoiding interference with other components. This utility model has a simple structure and low cost. Because this utility model uses a single bag-supporting mechanism, it occupies less space and has lower equipment costs for packaging bags of the same size, while also offering more stable operation.

[0016] 2. This utility model adds an installation frame and an installation plate, assembling the bag-supporting mechanism on the installation plate, and driving the installation plate to move up and down on the installation frame through a drive mechanism, thereby improving the stability of the bag-supporting mechanism when moving between the two workstations of bagging and material filling.

[0017] 3. The symmetrically arranged first and second bag-supporting plates apply force more evenly to the opening of large-sized packaging bags, ensuring the symmetry and stability of the bag opening and preventing skewing, which facilitates smooth filling of subsequent materials. Simultaneously, the spring force ensures that the bag-supporting plates always hold against the inner wall of the bag, preventing the packaging bag from detaching from the plates during the movement of the bag-supporting mechanism, thus guaranteeing the stability of the bagging process.

[0018] 4. The extension section and top block provide a reliable point of application for the external mechanism to drive the closure of the bag support plate. By transmitting force through the top block, the bag support plate can be driven to rotate around the rotating connection more accurately and effectively, making the opening and closing action of the bag support plate smoother and more stable, reducing the jamming phenomenon during the opening and closing process of the bag support plate, and improving the reliability of the device.

[0019] 5. When the bag-supporting mechanism reaches its highest position, the pusher mechanism acts on the top block to bring the bag-supporting plates closer together, making it easier for operators or the bag-loading mechanism to place large-sized packaging bags onto the bag-supporting plates, reducing the difficulty of the bag-loading operation. After the packaging bag is in place, the pusher mechanism retracts, and the bag-supporting plates open again under the action of the spring to fix the bag opening. The entire process is highly automated, convenient to operate, and ensures the accuracy of bag loading.

[0020] 6. The push rod cylinder provides a stable driving force, ensuring the reliability and timeliness of the push rod's extension and retraction. The parallel first and second push rods can apply forces to the first and second bag support plates respectively, making the movement of the two bag support plates more synchronized. This avoids the problem of inconsistent opening and closing of the bag support plates due to uneven force, further improving the coordination and stability of the bag support mechanism.

[0021] 7. The mounting base provides a stable foundation for the push rod cylinder, ensuring that the cylinder will not shake or shift during operation and guaranteeing the accuracy of the push rod mechanism's position. Simultaneously, assembling the mounting base onto the frame allows the push rod mechanism to form a stable whole with the other parts of the bagging device, improving the overall structural stability of the device.

[0022] 8. Parallel vertical slide rails provide precise guidance for the up-and-down sliding of the mounting plate, ensuring that the mounting plate will not deviate or tilt during movement, thus guaranteeing the accuracy of the bag-supporting mechanism's movement trajectory. The cooperation between the slider and the slide rails makes the sliding of the mounting plate smoother, reduces friction during movement, lowers the load on the drive components, and improves the operating efficiency and service life of the device.

[0023] 9. The bag-supporting displacement motor assembly provides stable power output. Through the transmission of the swing arm and connecting rod, the rotational motion of the motor is converted into the reciprocating linear motion of the mounting plate, resulting in high transmission efficiency and smooth movement. This transmission method can precisely control the movement speed and displacement of the mounting plate, ensuring that the bag-supporting mechanism can accurately reach the bagging station and material filling station, meeting the positional accuracy requirements during the bagging and filling of large-size packaging bags.

[0024] 10. The base plate provides stable support for the entire mounting frame, ensuring that it will not sway during operation. The first and second supports are arranged parallel and vertically, ensuring the structural symmetry and stability of the mounting frame. The addition of transverse reinforcing plates further enhances the overall rigidity of the mounting frame, improving its load-bearing capacity for components such as the mounting plate and drive assembly, thus maintaining structural stability during long-term operation.

[0025] 11. Fixing the slide rails to the first and second supports respectively fully utilizes the structural strength of the supports, ensuring the firmness and stability of the slide rail installation. Simultaneously, this installation method effectively guarantees the parallelism between the slide rails, further improving the smoothness and accuracy of the mounting plate's sliding, ensuring the stability of the bag-supporting mechanism during its up-and-down movement, and facilitating the bagging of large-sized packaging bags and material filling operations.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 7 As shown, this utility model discloses a single-station bagging device, the core structure of which includes a vertically arranged mounting frame 1, a mounting plate 2 slidably mounted on the mounting frame 1, and a drive assembly 3 connected to the mounting plate 2 and driving it to slide up and down along the mounting frame 1. The mounting plate 2 has a feeding groove 4, and a bag-opening mechanism 5 for opening the bag opening is installed at the feeding groove 4.

[0029] The bag-supporting mechanism 5 has the following structure: it includes a first bag-supporting plate 6 and a second bag-supporting plate 7, which are rotatably connected to both sides of the feed channel 4 and are arranged symmetrically. Springs are installed between the first bag-supporting plate 6 and the second bag-supporting plate 7 and the mounting plate 2. Under the elastic force of the springs, the first bag-supporting plate 6 and the second bag-supporting plate 7 can move away from each other, thereby opening the bag opening and supporting it against the inner wall of the bag, ensuring the stability of the packaging bag on the bag-supporting mechanism 5.

[0030] To facilitate control of the opening and closing of the bag support plate, the connection between the first bag support plate 6 and the mounting plate 2 is provided with an extension 8 extending outward, and the extension 8 is provided with a top block 9; the connection between the second bag support plate 7 and the mounting plate 2 is also provided with an extension 8 extending outward, and the extension 8 is also provided with a top block 9.

[0031] When the drive assembly 3 drives the bag-supporting mechanism 5 to its highest position, a push rod mechanism 10 is correspondingly provided on the other side of the mounting plate 2 relative to the bag-supporting mechanism 5. After the push rod mechanism 10 extends, it can act on the top block 9 of the extension 8 of the first bag-supporting plate 6 and the second bag-supporting plate 7, thereby driving the first bag-supporting plate 6 and the second bag-supporting plate 7 to move closer to each other around the connection point where they are rotatably connected to the mounting plate 2, which facilitates the bag-filling operation.

[0032] The push rod mechanism 10 consists of the following components: a push rod cylinder 11, a push rod mounting plate 12, a first push rod 13, and a second push rod 14. The push rod mounting plate 12 is mounted on the push rod cylinder 11. The first push rod 13 and the second push rod 14 are arranged in parallel, with one end of each fixedly mounted on the push rod mounting plate 12 and the other end being a free end. When the push rod cylinder 11 extends, the free ends of the first push rod 13 and the second push rod 14 act on the top blocks 9 of the first support plate 6 and the second support plate 7, respectively, causing the two support plates to move closer together.

[0033] In addition, the push rod mechanism 10 also includes a mounting base 15, on which the push rod cylinder 11 is mounted, and the mounting base 15 is mounted on the frame 16, thereby ensuring the stability of the push rod mechanism 10 during operation.

[0034] The mounting bracket 1 is provided with a pair of parallel slide rails 17, which are vertical. The mounting plate 2 is provided with a slider 18 that cooperates with the slide rails 17. The mounting plate 2 slides on the slide rails 17 via the slider 18, ensuring the stability and accuracy of the up and down movement of the mounting plate 2.

[0035] The drive assembly 3 consists of a bag-supporting displacement motor assembly 19, a swing arm 20, and a connecting rod 21. One end of the swing arm 20 is fixedly mounted on the output shaft of the bag-supporting displacement motor assembly 19, and one end of the connecting rod 21 is hinged to the other end of the swing arm 20, while the other end of the connecting rod 21 is hinged to the mounting plate 2. The bag-supporting displacement motor assembly 19 drives the swing arm 20 to rotate, and the power is transmitted through the connecting rod 21, thereby realizing the up-and-down reciprocating sliding of the mounting plate 2.

[0036] The mounting bracket 1 has the following structure: a base plate 22, a first bracket 23, a second bracket 24, and a transverse reinforcing plate 25. The first bracket 23 and the second bracket 24 are mounted parallel and vertically on the base plate 22. One end of the transverse reinforcing plate 25 is connected to the first bracket 23, and the other end is connected to the second bracket 24, thereby enhancing the overall structural strength of the mounting bracket 1. Furthermore, a pair of slide rails 17 are respectively fixedly mounted on the first bracket 23 and the second bracket 24.

[0037] The working principle of this utility model is as follows: When a bagging operation is required, the drive assembly 3 drives the mounting plate 2 and the bag-supporting mechanism 5 to move to the highest position. At this time, the pusher cylinder 11 of the pusher mechanism 10 extends, driving the first pusher 13 and the second pusher 14 to act on the top block 9 on the first bag-supporting plate 6 and the second bag-supporting plate 7, so that the first bag-supporting plate 6 and the second bag-supporting plate 7 move closer to each other, and the bag-up mechanism can then put the large-sized packaging bag onto the first bag-supporting plate 6 and the second bag-supporting plate 7. Subsequently, the pusher cylinder 11 retracts, and the first pusher 13 and the second pusher 14 no longer apply force to the top block 9. Under the tension of the spring, the first bag-supporting plate 6 and the second bag-supporting plate 7 move away from each other, opening the bag opening and holding the inner wall of the bag. Next, the drive assembly 3 drives the mounting plate 2 and the bag-supporting mechanism 5 to move downward to the lowest position, at which time materials can be filled into the packaging bag through the feeding channel 4. After the material is filled, the drive component 3 drives the mounting plate 2 and the bag-supporting mechanism 5 to move upward to the highest position again to perform the next bagging operation. This process is repeated to complete the continuous bagging work.
