[0028] Embodiment 1:

[0029] like Figure 1-Figure 3 As shown, the utility model provides a valve bag packaging machine 1, comprising: a packaging machine body 10, a weighing device 20 and a tray 30, the packaging machine body 10 is provided with a mounting groove 11, the weighing device 20 is received in the mounting groove 11 and connected to the packaging machine body 10, the weighing device 20 is provided with a weighing end, the weighing end is movably arranged in the mounting groove 11, the tray 30 is rotatably arranged at the weighing end, and the tray 30 is suitable for placing the valve bag; wherein the weighing device 20 is suitable for determining the weight of the valve bag according to the displacement of the weighing end.

[0030] In some embodiments, a working space is provided in the packaging machine body 10, and a discharge pipe 50 is provided on a side wall of the packaging machine body 10. The discharge pipe 50 is used for valve bag sleeve installation. The side wall is also provided with a mounting groove 11. The mounting groove 11 is located below the discharge pipe 50. A weighing device 20 is provided in the mounting groove 11, and the weighing end of the weighing device 20 can be selectively moved in the mounting groove 11, and the movable end is rotatably connected to the tray 30.

[0031] It can be understood that the packaging machine body 10 is suitable for being connected to a material storage bin, and the working space inside the packaging machine body 10 is connected to the material storage bin. When receiving materials, the staff can place the valve bag on the tray 30 and put the valve bag on the discharge pipe 50. Then, the staff starts the valve bag packaging machine 1. The material in the material storage bin enters the working space and can be discharged to the valve bag through the discharge pipe 50. As the material in the valve bag increases, the weight of the valve bag increases accordingly, and the weighing end then moves in the mounting groove 11. The weighing device 20 can determine the weight borne by the tray 30 according to the displacement of the weighing end. The weight borne by the tray 30 is the weight of the material loaded in the valve bag.

[0032] It is worth mentioning that the tray 30 is rotatably connected to the weighing end, that is, the tray 30 can rotate relative to the weighing end. When the valve bag packaging machine 1 is stopped, the staff can rotate the tray 30 to make the tray 30 fit with the side wall of the packaging machine body 10 to prevent the tray 30 from protruding from the packaging machine body 10, thereby reducing the volume of the valve bag packaging machine 1 and further reducing the occupied space of the valve bag packaging machine 1.

[0033] Of course, when the valve bag packaging machine 1 is transported, the staff can also rotate the tray 30 to fit the side wall of the packaging machine body 10 to prevent the tray 30 from protruding from the packaging machine body 10, thereby making the structure of the valve bag packaging machine 1 more regular and facilitating the packaging and transportation of the valve bag packaging machine 1.

[0034] According to the valve bag packaging machine 1 of the utility model, its tray 30 is rotatably connected to the weighing end of the weighing device 20, and the staff can rotate the tray 30 according to the actual situation. When the valve bag packaging machine 1 is shut down or transported, the staff can rotate the tray 30 and make the tray 30 fit with the packaging machine body 10 to avoid the tray 30 protruding from the packaging machine body 10, thereby making the valve bag packaging machine 1 occupy smaller space and at the same time making the structure of the valve bag packaging machine 1 more regular, which is convenient for the storage and transportation of the valve bag packaging machine 1.

[0035] Embodiment 2:

[0036] In this embodiment, based on the first embodiment, the tray 30 is rotatable and can be selectively fixed at a first position and a second position. In the first position, the tray 30 is in contact with the packaging machine body 10 ; in the second position, an angle is formed between the tray 30 and the packaging machine body 10 .

[0037] It can be understood that the tray 30 can rotate relative to the weighing end, so as to realize the rotation of the tray 30 relative to the packaging machine body 10. The tray 30 can be fixed in a first position or a second position. When the tray 30 is fixed in the first position, the tray 30 is in contact with the packaging machine body 10. At this time, the tray 30 does not protrude from the packaging machine body 10, which can facilitate the storage and transportation of the packaging machine body 10. Moreover, since the tray 30 can be fixed in the first position, the above-mentioned arrangement can also prevent the tray 30 from rotating relative to the packaging machine body 10 during transportation, thereby preventing the tray 30 from rotating and contacting other transported items and causing damage to each other. When the tray 30 is fixed in the second position, there is an angle between the tray 30 and the packaging machine body 10. At this time, the tray 30 can be used to place the valve bag, and the tray 30 can stably support the valve bag.

[0038] According to some embodiments of the present invention, in the second position, the angle between the tray 30 and the packaging machine body 10 is α, which satisfies: 80°≤α≤100°.

[0039] In some embodiments, when the tray 30 is fixed in the second position, the angle α between the tray and the packaging machine body 10 is between 80° and 100°, and α can be 80°, 81°, 85°, 90°, 95°, 99°, 100°, etc., which is not limited here. The present application can stably support the valve bag by controlling 80°≤α≤100°, so that the staff can stably carry out the material receiving work.

[0040] It is understandable that when α is less than 80° and the valve bag is filled with material, the pallet will hinder the removal of the valve bag, making it inconvenient to remove the valve bag filled with material, thereby increasing the difficulty of the material receiving work; when α is greater than 100° and the valve bag is filled with material, the valve bag will tend to slide off the pallet under the action of its own gravity, increasing the difficulty of the material receiving work.

[0041] Embodiment three:

[0042] In this embodiment, on the basis of the second embodiment, the packaging machine body 10 is provided with a receiving groove 12 , and when in the first position, the tray 30 is received in the receiving groove 12 .

[0043] In some embodiments, a receiving groove 12 is provided on the side wall of the packaging machine body 10, and a mounting groove 11 is provided at the bottom of the receiving groove 12. The receiving groove 12 is suitable for accommodating the tray 30. Therefore, when the tray 30 is rotated to the first position and fixed at the first position, the tray 30 can be accommodated in the receiving groove 12, thereby preventing the tray 30 that is attached to the packaging machine body 10 from protruding out of the packaging machine body 10, thereby further reducing the volume of the valve bag packaging machine 1 when the tray 30 is located in the first position.

[0044] According to some embodiments of the present invention, the valve bag packaging machine 1 further comprises: a fixing plate 40 rotatably disposed on the packaging machine body 10 , and the fixing plate 40 rotates to selectively fix the tray 30 at the first position.

[0045] In some embodiments, a rotatable fixing plate 40 is further provided on the packaging machine body 10. When the tray 30 rotates to the first position, the fixing plate 40 can be rotated to stop against the bottom wall of the tray 30. As a result, the tray 30 stops against the fixing plate 40 and the packaging machine body 10 on both sides in the thickness direction, that is, the fixing plate 40 cooperates with the packaging machine body 10 to limit and fix the tray 30 in the first position, thereby preventing the tray 30 from rotating relative to the packaging machine body 10 after being fixed in the first position, thereby improving the stability of the tray 30 after being fixed in the first position.

[0046] Embodiment 4:

[0047] In this embodiment, based on the second embodiment, the weighing device 20 includes: a mounting cylinder 21, a reset member 22, a moving rod 23 and a displacement sensor. The mounting cylinder 21 is connected to the inner wall of the mounting groove 11. A mounting channel is provided in the mounting cylinder 21. The reset member 22 is provided in the mounting channel, and one end of the reset member 22 is connected to the inner wall of the mounting channel. The moving rod 23 is constructed as a weighing end. At least a part of the moving rod 23 is movably accommodated in the mounting channel and connected to the reset member 22. The displacement sensor is connected to the mounting cylinder 21 and is suitable for detecting the displacement of the moving rod 23.

[0048] In some embodiments, the mounting cylinder 21 is suitable for connecting to at least one inner wall of the mounting groove 11, a mounting channel is formed in the mounting cylinder 21, and at least one end of the mounting channel in the axial direction is open, the reset member 22 is accommodated in the mounting channel and one end of the reset member 22 is connected to the inner wall of the mounting channel, the other end of the reset member 22 is connected to the moving rod 23, the free end of the moving rod 23 extends outside the mounting channel and is rotatably connected to the tray 30, and the displacement sensor is connected to the mounting cylinder 21.

[0049] It can be understood that when the tray 30 bears the weight of the valve bag and the material in the valve bag, the tray 30 can drive the moving rod 23 to move vertically downward and cause the reset member 22 to deform. At this time, the displacement sensor can detect the movement of the moving rod 23, and the displacement sensor can calculate the weight borne by the tray 30 according to the movement of the moving rod 23 (the weight borne by the tray 30 is the weight of the material), thereby realizing that the valve bag can be accurately loaded with a preset value of material.

[0050] And when the valve bag is filled with materials and the valve bag is removed, the reset force of the reset member 22 can drive the moving rod 23 to move to the initial position, thereby realizing the zeroing of the weighing device 20, which is convenient for the next material receiving work. It is worth mentioning that when the moving rod 23 moves, the inner peripheral wall of the installation channel can limit the outer peripheral wall of the moving rod 23, so that the moving rod 23 can stably move along the extension direction of the installation channel, and then the displacement sensor can accurately detect the displacement of the moving rod 23, thereby realizing the accurate detection of the weight of the material loaded in the valve bag. It is worth mentioning that the reset member 22 can be a spring, etc., which is not limited here.

[0051] Embodiment five:

[0052] In this embodiment, based on the fourth embodiment, the movable rod 23 includes: a main body 231 and a limiting portion 232, at least a portion of the main body 231 is movably arranged in the installation channel, and the main body 231 is rotatably connected to the tray 30, the limiting portion 232 is connected to the other end of the main body 231, and an angle is formed between the limiting portion 232 and the main body 231; wherein the limiting portion 232 is suitable for abutting against the bottom of the tray 30 to fix the tray 30 in the second position.

[0053] It can be understood that at least a portion of the main body 231 is accommodated in the installation channel, and one end of the main body 231 accommodated in the installation channel is connected to the reset member 22, and the other end of the main body 231 extends outside the installation channel and is connected to the limiting portion 232. The side of the main body 231 close to the limiting portion 232 is rotatably connected to the tray 30. When the tray 30 rotates, the limiting portion 232 is suitable for stopping with the bottom of the tray 30 when the tray 30 rotates, thereby fixing the tray 30 in the second position, so that the tray 30 can stably support the valve bag, ensuring the smooth progress of the material receiving work.

[0054] According to some embodiments of the present invention, two weighing devices 20 are configured, and the two weighing devices 20 are rotatably connected to the tray 30 respectively.

[0055] It can be understood that when the pallet 30 is bearing weight, the two weighing devices 20 can share the weight more evenly. Especially when processing large-volume materials or materials with unstable center of gravity, the above arrangement can effectively avoid unilateral overload, reduce the risk of tilting, and maintain the balance and stability of the entire system.

[0056] At the same time, the two weighing devices 20 can perform dual measurements on the weight of the valve bag, which can not only verify the results with each other and reduce errors caused by failure or deviation of a single displacement sensor, but also use average values ​​or other algorithms in calculation to further improve the accuracy and stability of the final weighing.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
