Description

Technical Field

[0001] This utility model relates to the field of fully automatic ton bag machine technology, specifically to a bag blowing assembly for the bag loading mechanism of a ton bag machine. Background Technology

[0002] The fully automatic ton bag machine is a special equipment used for automated production of ton bag filling. It mainly realizes the fully automated operation from bulk materials to ton bag filling, and is widely used in the packaging of large-capacity bulk materials in industries such as chemical, building materials, grain, and mining.

[0003] In the automated bag loading process of ton bag machines, a clamping device is typically used to hold and position the two sides of the bag opening so that the bag clamping cylinder can be lowered and inserted into the bag opening to complete the bag loading operation. However, existing ton bag loading clamping devices have significant drawbacks in practical applications: because only the two sides of the ton bag are clamped, the other two sides of the bag opening are prone to collapse and stick together due to lack of support. In this state, when the bag clamping cylinder is lowered and inserted into the ton bag opening, the collapsed and stuck bag walls are easily scraped or squeezed by the edge of the bag clamping cylinder, causing damage to the ton bag. This not only affects the bag loading and packaging efficiency but may also cause material leakage and other problems, increasing material loss and equipment maintenance costs in the production process. Therefore, how to effectively solve the problem of collapse and sticking of the non-clamping side of the bag opening during the bag loading process and avoid damage to the bag body when the bag clamping cylinder is inserted has become a key technical challenge to improve the reliability of ton bag loading operations. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a bag blowing assembly for the bag loading mechanism of a ton bag machine. This device solves the problems of natural collapse and adsorption adhesion caused by the lack of support at the bag opening of the ton bag.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] The bag blowing assembly for the bag loading mechanism of this utility model includes a horizontally arranged crossbeam. Two vertically arranged fixed rods are fixedly installed on the lower end face of the crossbeam. An inclined downward movable rod is installed on the crossbeam between the two fixed rods. A drive mechanism for driving the movable rod to rotate is installed on the movable rod. An outer support plate is connected to the lower end face of the movable rod, and an inner support plate is connected to the lower end face of the fixed rod. The lower end faces of the outer support plate and the inner support plate are flush. An air blowing mechanism is installed on the end face of the inner support plate away from the outer support plate.

[0007] In the above solution, the air-blowing mechanism, through the cooperation of the inner and outer support plates, effectively supports the bag opening from both the inside and outside of the ton bag, keeping the bag opening open. The air-blowing mechanism on the inner support plate blows air into the bag opening, further blowing open any collapsed bag walls, ensuring the bag opening remains open and facilitating the smooth insertion of the bag clamping cylinder. This effectively prevents damage to the ton bag, thus solving the problem of the bag opening lacking support, leading to natural collapse and adhesion issues. The lower surfaces of the outer and inner support plates are flush, ensuring that the support and air-blowing action on the ton bag are at the same height, improving the stability of the blowing effect. The movable rod can be rotated via a drive mechanism to adjust the position of the outer support plate, adapting to the opening requirements of different ton bag sizes, offering high flexibility.

[0008] The air blowing mechanism includes a three-way valve and two air blowing pipes. The three-way valve has an upper valve port, a lower valve port, and a side valve port. The two air blowing pipes are respectively sealed and inserted into the upper and lower valve ports of the three-way valve. The side valve port of the three-way valve is connected to an external air source through a pipeline, and the air outlets of the two air blowing pipes are both facing the inside of the ton bag to be blown open.

[0009] The above solution, through the setting of a three-way valve and a blow-through pipe, can simultaneously blow air into the inside of the ton bag from two different positions, thereby expanding the blowing coverage area and improving the blowing efficiency and effect; the blow-through pipe and the three-way valve adopt a sealed insertion method to ensure the air circuit is sealed, reduce gas leakage, and ensure stable blowing pressure; the air outlets of both blow-through pipes are directed towards the inside of the ton bag to be blown open, so that the airflow directly acts on the easily collapsed bag wall, which can effectively blow open the adhered bag wall.

[0010] A speed regulating valve is connected in series on the pipeline between the side valve port of the three-way valve and the external gas source gas line to regulate the flow rate of gas entering the three-way valve.

[0011] The above solution, through the setting of the speed regulating valve, can precisely adjust the gas flow rate and velocity entering the three-way valve according to the material, thickness and opening requirements of different specifications of ton bags, thereby flexibly controlling the blowing intensity; and the blowing tube can be manually adjusted in angle, and the blowing direction can be changed according to actual needs, so that the airflow can be more accurately applied to the parts of the ton bag that are prone to collapse. The combination of the two can adapt to the blowing needs of various specifications of ton bags, which helps to improve the versatility of the blowing component and the stability of the blowing effect.

[0012] The blow-bag tube is either a brass blow-bag tube or a stainless steel blow-bag tube.

[0013] By adopting the above solution, the blow-through tube has good rigidity, can maintain a stable blowing angle and position, and avoids deformation due to airflow impact or contact with the ton bag; moreover, both brass and stainless steel have good corrosion resistance and wear resistance, which helps to extend the service life of the blow-through tube.

[0014] The drive mechanism includes a first cylinder, a fixed seat is fixedly provided on the lower end face of the crossbeam, a fixed ring is fixedly provided on the upper end face of the movable rod, and a rotating shaft is inserted between the fixed seat and the fixed ring; one end of the first cylinder is fixedly connected to the crossbeam, and the piston rod of the first cylinder is fixedly connected to the movable rod.

[0015] In the above scheme, the first cylinder is set up and used as a drive mechanism. The piston rod extends and retracts, driving the movable rod to rotate around the pivot, thereby precisely adjusting the position of the inner support plate.

[0016] A second cylinder is provided on the side of the outer support plate away from the inner support plate. A push plate is fixed on the piston rod of the second cylinder. A through hole adapted to the push plate is provided on the outer support plate.

[0017] In the above solution, the second cylinder drives the push plate through the through hole in the outer support plate, cooperating with the inner support plate to open the ton bag opening, effectively preventing the bag wall from collapsing and sticking. The push plate and through hole design ensure precise positioning during push plate movement, avoiding scratching or damage to the ton bag. The pushing amplitude can be adjusted according to the bag size using the second cylinder.

[0018] By opening the bag opening with a push plate and an inner support plate, and blowing air through the bag blowing tube, the bag wall of the ton bag can be blown open. This method is suitable for ton bags made of soft materials that are easy to fit.

[0019] The above solution has the following advantages:

[0020] 1. Because the bag-feeding mechanism of this utility model uses a bag-blowing assembly, the inner and outer support plates work together to effectively support the bag opening from both the inside and outside of the ton bag, keeping the bag opening open. The air-blowing mechanism on the inner support plate blows air into the inside of the bag opening, further blowing open the collapsed bag wall and ensuring the bag opening remains open, facilitating the smooth insertion of the subsequent bag clamping cylinder and effectively preventing damage to the ton bag. The lower surfaces of the outer and inner support plates are flush, ensuring that the support and air-blowing action on the ton bag are on the same height plane, improving the stability of the bag-blowing effect. The movable rod can be rotated by the drive mechanism to adjust the position of the outer support plate, adapting to the opening requirements of ton bags of different sizes, providing high flexibility.

[0021] 2. By using a three-way valve and a blow-through pipe, air can be blown into the inside of the ton bag from two different positions simultaneously, thereby expanding the blowing coverage area and improving the blowing efficiency and effect. The blow-through pipe and the three-way valve adopt a sealed insertion method to ensure the air circuit is sealed, reduce gas leakage, and ensure stable blowing pressure. The air outlets of both blow-through pipes are directed towards the inside of the ton bag to be blown open, so that the airflow acts directly on the easily collapsed bag wall, which can effectively blow open the adhered bag wall.

[0029] 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.

[0030] In specific embodiment 1, such as Figures 1-5As shown, the bag blowing assembly for the bag loading mechanism of the ton bag machine of this utility model includes a horizontally arranged crossbeam 1. Two vertically arranged fixed rods 2 are fixedly installed on the lower end face of the crossbeam 1. An inclined downwardly arranged movable rod 3 is installed on the crossbeam 1 between the two fixed rods 2. A drive mechanism for driving the movable rod 3 to rotate is installed on the movable rod 3. An outer support plate 4 is connected to the lower end face of the movable rod 3. An inner support plate 5 is connected to the lower end face of the fixed rod 2. The lower end faces of the outer support plate 4 and the inner support plate 5 are flush. An air blowing mechanism is installed on the end face of the inner support plate 5 away from the outer support plate 4. First, the inner support plate 5 and the outer support plate 4 work together to effectively support the bag opening from both the inside and outside of the ton bag, keeping the bag opening open. The air blowing mechanism on the inner support plate 5 blows air into the inside of the bag opening, further blowing open the collapsed bag wall and ensuring that the bag opening remains open, facilitating the smooth insertion of the bag clamp and effectively preventing damage to the ton bag. The lower ends of the outer support plate 4 and the inner support plate 5 are flush, ensuring that the support and air blowing action on the ton bag are on the same height plane, improving the stability of the bag blowing effect. The movable rod 3 can be rotated by the drive mechanism to adjust the position of the outer support plate 4, adapting to the opening requirements of ton bags of different sizes, providing high flexibility.

[0031] like Figure 4 As shown, the air blowing mechanism includes a three-way valve 6 and two blowing pipes 7. The three-way valve 6 has an upper valve port, a lower valve port, and a side valve port. The two blowing pipes 7 are respectively sealed and inserted into the upper and lower valve ports of the three-way valve 6. The side valve port of the three-way valve 6 is connected to an external air source through a pipeline, and the outlet ends of both blowing pipes 7 face the inside of the ton bag to be blown open. Through the arrangement of the three-way valve 6 and the blowing pipes 7, air can be blown into the inside of the ton bag simultaneously from two different positions, thereby expanding the blowing coverage area and improving the blowing efficiency and effect. The sealed insertion method between the blowing pipes 7 and the three-way valve 6 ensures the airtightness of the air path, reduces gas leakage, and ensures stable blowing pressure. The fact that the outlet ends of both blowing pipes 7 face the inside of the ton bag to be blown open allows the airflow to directly act on the easily collapsible bag wall, effectively blowing open the adhered bag wall.

[0032] like Figure 3 As shown, the drive mechanism includes a first cylinder 8. A fixed seat 9 is fixedly mounted on the lower end face of the crossbeam 1, and a fixed ring is fixedly mounted on the upper end face of the movable rod 3. A rotating shaft is inserted between the fixed seat 9 and the fixed ring. One end of the first cylinder 8 is fixedly connected to the crossbeam 1, and the piston rod of the first cylinder 8 is fixedly connected to the movable rod 3. When the first cylinder 8 is activated as the drive mechanism, the piston rod extends and retracts, causing the movable rod 3 to rotate around the rotating shaft, thereby precisely adjusting the position of the inner support plate 5.

[0033] like Figure 5As shown, a second cylinder 10 is installed on the side of the outer support plate 4 away from the inner support plate 5. A push plate 11 is fixed on the piston rod of the second cylinder 10, and a through hole 12 adapted to the push plate 11 is provided on the outer support plate 4. The second cylinder 10 drives the push plate 11 to pass through the through hole 12 of the outer support plate 4 and cooperate with the inner support plate 5, thereby opening the mouth of the ton bag and effectively preventing the bag wall from collapsing and sticking. The setting of the push plate 11 and the through hole 12 ensures that the push plate 11 is accurately positioned when it moves, avoiding scratching or damage to the ton bag. The pushing amplitude can be adjusted by the second cylinder 10 according to the bag size.

[0034] The bag opening is opened by pushing the push plate 11 and the inner support plate 5, and air is blown out by the blowing tube 7, which can blow open the bag wall of the ton bag. It is suitable for ton bags with softer materials and easy to fit.

[0035] In specific embodiment 2, the difference between this embodiment and embodiment 1 is that a speed regulating valve is connected in series on the pipeline between the side valve port of the three-way valve 6 and the external air source air path to regulate the gas flow rate entering the three-way valve 6. The gas flow rate and velocity entering the three-way valve 6 can be precisely adjusted according to the material, thickness and opening requirements of different specifications of ton bags, thereby flexibly controlling the blowing intensity. In addition, the blowing pipe 7 can be manually adjusted in angle, and the blowing direction can be changed according to actual needs, so that the airflow can more accurately act on the parts of the ton bag that are prone to collapse. The combination of the two can adapt to the blowing needs of various specifications of ton bags, which is conducive to improving the versatility of the blowing assembly and the stability of the blowing effect.

[0036] In specific embodiment 3, the difference between this embodiment and embodiments 1 and 2 is that the blow-bag tube 7 in this embodiment is made of brass, stainless steel or other blow-bag tubes with the same rigidity characteristics in the prior art. The rigid blow-bag tube 7 can maintain a stable blowing angle and position, and avoid deformation due to airflow impact or contact with the ton bag; and both brass and stainless steel have good corrosion resistance and wear resistance, which is beneficial to extending the service life of the blow-bag tube 7.

[0037] The working process is as follows: The first cylinder 8 and the second cylinder 10 are started. The first cylinder 8 drives the movable rod 3 to rotate, which in turn drives the outer support plate 4 to move. The second cylinder 10 pushes the push plate 11 to move. The two work together to clamp the mouth of the ton bag. At the same time, the air outlets of the two blowing pipes 7 blow air towards the inside of the ton bag to be blown open, blowing open the originally attached bag wall. At this time, the driving bag clamping cylinder moves down into the ton bag, which can effectively prevent the bag clamping cylinder from tearing the ton bag.
