Description

Technical Field

[0001] This invention relates to the field of valve bag testing technology, and more specifically to a valve bag overall strength testing device. Background Technology

[0002] Valve bags (also known as glued bottom bags) are small bulk packaging containers with a square overall shape and a valve at the bottom or top for easy filling of materials. After filling, they form a three-dimensional structure, making them suitable for automated mechanical filling and stacking transportation.

[0003] Valve bags produced in batches generally require sample strength testing before being used for mass filling to meet the requirements for impact, collision and stacking during transportation and storage.

[0004] Chinese patent CN117268924B discloses a multi-layer paper valve pocket strength testing device, including a testing upright plate, two clamping support plates, a clamping flip plate, a multi-stage cylinder installed between the two clamping support plates, an inner support component connected to the telescopic end of the multi-stage cylinder, and testing components installed on opposite sides of the two clamping support plates.

[0005] The aforementioned patent employs a multi-functional approach to test the tensile and burst strength of multi-layer paper valve bags of different models. It can apply force separately to the middle of the closed end of the paper valve bag to analyze whether the sealing strength meets the requirements. In addition, it can quickly adjust the different models of valve bags during strength testing, increasing the efficiency and accuracy of the test.

[0006] However, this patent has the following drawbacks: 1. It is inconvenient to put in and take out the valve bag under test; 2. In actual transportation, the valve bag may be subjected to dropping or impact, but this patent does not test the strength generated after dropping or impacting; 3. It is impossible to use the gravity of the valve bag after filling for testing, which increases energy consumption and costs; 4. It is not possible to stack several valve bags to simulate actual manual handling. Therefore, a valve bag overall strength testing device is proposed to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to address four problems in existing multi-layer paper valve bag strength testing devices: inconvenience in placing and removing the valve bag; lack of testing of the strength generated after dropping; inability to utilize the gravity of the valve bag after filling, resulting in increased energy consumption and costs; and inability to stack multiple valve bags to simulate actual manual handling. This invention provides a valve bag overall strength testing device.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0009] A valve bag overall strength testing device includes a housing, an inner rod, and a base. The inner rod extends and retracts within the housing via a power system. The base is connected to the lower part of the housing. A pressure-bearing mechanism includes a curved cylinder, a clamping mechanism, a flexing mechanism, and two elastic nets. The curved cylinder is connected between the two elastic nets, forming a peak-like or flat shape with them. The clamping mechanism and the flexing mechanism are respectively connected to the side of the two elastic nets away from the curved cylinder. The clamping mechanism includes a cover plate and a clamping plate, with the clamping plate movably connected to the cover plate. The clamping plate is used to clamp one end of the valve bag under test. The flexing mechanism is used to flexibly clamp the other end of the valve bag under test. A throwing mechanism includes a replacement slot formed on the surface of the curved cylinder. A throwing actuator is disposed within the replacement slot. The valve bag under test is placed on the upper side of the curved cylinder, and the housing and inner rod are positioned below the curved cylinder. The curved cylinder is made of an elastic material to form an arc or a straight line shape.

[0010] Furthermore, the throwing actuation assembly includes two side plates and a torsion spring, the torsion spring being connected between the two side plates.

[0011] Furthermore, the pressing mechanism also includes a first side post and a support ring plate. The first side post is connected to the support ring plate and the elastic net. The support ring plate is arc-shaped, with its concave surface close to the elastic net. The side of the support ring plate away from the first side post is connected to the cover plate.

[0012] Furthermore, a groove is formed on the surface of the cover plate, and an insert plate is connected to the side of the pressure plate near the cover plate. The insert plate is inserted into the groove, and a telescopic block is connected to the insert plate. A limiting groove is formed on the inner wall of the groove, and the telescopic block is inserted into the limiting groove.

[0013] Furthermore, the clamping plate is provided with a wedge-shaped protrusion on the side away from the elastic net, and the wedge-shaped protrusion abuts against one side surface of the cover plate so that the clamping plate is tilted towards the elastic net.

[0014] Furthermore, both ends of the ring piece are connected to auxiliary plates.

[0015] Furthermore, the live pressure mechanism includes a second side column, a side plate, and a connecting rod. The second side column has a through hole in the middle. A central shaft is connected to one side of the side plate. The central shaft is inserted into the hole. The side plate is sleeved on the connecting rod. A fixing hook is hooked on the connecting rod. A connecting piece is connected to the fixing hook. The end of the connecting piece away from the fixing hook is connected to the outer shell.

[0016] Furthermore, the pressure mechanism includes two connecting rods, each connecting rod being connected to one of the elastic nets by a connecting line, each connecting rod having a corresponding fixed hook, and each fixed hook having a corresponding connecting piece connected to it, the end of the connecting piece away from the fixed hook being connected to the outer shell.

[0017] Furthermore, one end of the connecting rod is connected to a binding rope, the other end of the connecting rod away from the binding rope is connected to a limiting protrusion, and the other end of the binding rope away from the connecting rod is connected to a collar, which is fitted onto the connecting rod and locked inside the limiting protrusion.

[0018] Furthermore, both ends of the curved cylinder are connected to limit plates.

[0019] The beneficial effects of this invention are as follows: By setting up components such as a curved cylinder, elastic net, pressing mechanism, and flexible pressing mechanism, this invention can easily put the valve bag under test into and take it out without any obstruction. It can also simulate the dropping operation during actual transportation, and the dropping operation is the best test of the overall strength of the valve bag. In addition, by using the gravity of the valve bag under test above, the energy consumption required for lifting during testing is reduced, thus reducing testing costs. Several valve bags can be stacked on top of the curved cylinder to simulate the situation during actual manual handling. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] In the description of the embodiments of the present invention, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0031] like Figure 1-6A valve pocket overall strength testing device includes a housing 11, an inner rod 12 and a base 17. The inner rod 12 extends and retracts within the housing 11 by a power system. The base 17 is connected to the bottom of the housing 11. To enable the extension and retraction of the inner rod 12 within the housing 11, the power system can be hydraulic, electric cylinder or pneumatic. The power system is not a basis for limiting this device.

[0032] The pressure-bearing mechanism 1 includes a curved cylinder 13, a pressing mechanism 14, a flexible pressure mechanism 15, and two elastic nets 16. The curved cylinder 13 is connected to the middle of the two elastic nets 16 and forms a mountain-shaped or flat shape with the two elastic nets 16. The valve bag to be tested can be easily placed on the mountain-shaped curved cylinder 13 and elastic nets 16. At this time, the middle of the valve bag to be tested is raised and the two sides hang down naturally. Most of the weight falls on the surface of the curved cylinder 13. When the inner rod 12 below the curved cylinder 13 supports the curved cylinder 13 to push it upward, there is an upward force from the inner rod 12 and a force from the curved cylinder 13 plus the weight of the valve bag to be tested. The overall strength measured in this way will be higher. Under the same strength test, with the support of gravity, the transmission energy consumed will be less. In addition, this mountain-shaped shape imitates a way of carrying valve bags, that is, carrying them on the shoulder for manual transport. Therefore, it can also simulate a carrying strength test that is closer to reality.

[0033] Two elastic nets 16 are connected to a clamping mechanism 14 and a movable clamping mechanism 15 on the side away from the curved cylinder 13, respectively. The clamping mechanism 14 includes a cover plate 143 and a clamping plate 144. The clamping plate 144 is movably connected to the cover plate 143 and is used to clamp one end of the valve bag to be tested. The movable clamping mechanism 15 is used to movably clamp the other end of the valve bag to be tested. While the clamping mechanism 14 is clamping and fixing, the movable clamping mechanism 15 is movably clamping. In this way, when it is necessary to throw the valve bag to be tested out for strength testing, the clamping mechanism 15 can be released from clamping the valve bag to be tested. The elastic force in the curved cylinder 13 comes from the combination of the side plate 22 inserted in the insertion slot 21 and the torsion spring 23, which gives the curved cylinder 13 a rebound force. At this time, the valve bag to be tested can be thrown out and thrown onto a plane to test the overall strength of the valve bag to be tested. This method is closer to the actual situation when the bag is put down from the shoulder and placed on the ground.

[0034] The ejection mechanism 2 includes an insertion slot 21, which is formed on the surface of the curved cylinder 13. An ejection actuator is disposed within the insertion slot 21. The valve bag to be tested is placed on the upper side of the curved cylinder 13, while the outer shell 11 and inner rod 12 are positioned below the curved cylinder 13. The curved cylinder 13 is made of an elastic material to form an arc or straight shape. When the valve bag to be tested needs to lie flat on the curved cylinder 13 and the elastic material... When the test valve bag is placed on the net 16, the curved cylinder 13 can be in a straight line shape. The elastic material of the curved cylinder 13 is rubber or thermoplastic elastomer. When the valve bag to be tested needs to be placed in a mountain-shaped position on the curved cylinder 13 and the elastic net 16, the curved cylinder 13 can be semi-circular, and the valve bag to be tested should be placed on the upper side of the curved cylinder 13. In the prior art, the valve bag to be tested is placed in the middle of several mechanisms or below the pressure mechanism. Compared with the prior art, it is more convenient to place the valve bag to be tested directly from the top in this embodiment.

[0035] like Figure 2 As shown, the throwing actuator includes two side plates 22 and a torsion spring 23. The torsion spring 23 is connected in the middle of the two side plates 22. The combination of the side plates 22 and the torsion spring 23 can give the cylinder 13 an elastic force. Both ends of the torsion spring 23 are connected to a side plate 22, so that there is a rebound force when the valve pocket being tested is thrown out.

[0036] like Figure 5 As shown, the clamping mechanism 14 also includes a first side post 141 and a support ring 142. The first side post 141 is connected to the support ring 142 and the elastic net 16. The support ring 142 is arc-shaped, with its concave surface close to the elastic net 16. The side of the support ring 142 away from the first side post 141 is connected to the cover plate 143. The support ring 142 supports the valve bag to be tested, with its concave surface facing the elastic net 16, making the valve bag to be tested more stable after it is placed.

[0037] like Figure 6 As shown, a slot 145 is formed on the surface of the cover plate 143. A plate 146 is connected to the side of the clamping plate 144 near the cover plate 143. The plate 146 is inserted into the slot 145. A telescopic block is connected to the plate 146. A limiting groove is formed on the inner wall of the slot 145. The telescopic block is inserted into the limiting groove. The plate 146 is inserted into the slot 145. The telescopic block and the limiting groove abut against each other. In this way, the clamping plate 144 will be stably fixed on one side of the cover plate 143, pressing the surface of the valve bag to be tested, so that when the valve bag to be tested is thrown out, one side will not fall off due to the force of the throw.

[0038] like Figure 6As shown, the clamping plate 144 has a wedge-shaped protrusion 147 on the side away from the elastic net 16. The wedge-shaped protrusion 147 abuts against one side surface of the cover plate 143, so that the clamping plate 144 is tilted towards the elastic net 16, so that the clamping plate 144 and the valve bag under test form an inner angle clamping. It is necessary to set a wedge-shaped protrusion 147 on one side of the clamping plate 144, so that one side of the clamping plate 144 is pushed up and tilted towards the valve bag under test, forming an inner angle of less than 90 degrees, making the clamping of the valve bag under test more secure.

[0039] like Figure 4 As shown, both ends of the support ring 142 are connected to auxiliary plates 148, which facilitates placing the valve bag to be tested in the center of the support ring 142 and prevents it from shifting to one side.

[0040] like Figure 4 As shown, the pressure mechanism 15 includes a second side post 151, a side plate 152, and a connecting rod 153. The second side post 151 has a through hole in the middle. A central shaft is connected to one side of the side plate 152, and the central shaft is inserted into the hole. The side plate 152 is sleeved on the connecting rod 153. A fixing hook 24 is hooked on the connecting rod 153, and a connecting piece 25 is connected to the fixing hook 24. The end of the connecting piece 25 away from the fixing hook 24 is connected to the outer shell 11. In this embodiment, the connecting rod 153 is connected to the central shaft through the side plate 152. At this time, the connecting rod 153 can rotate with the rotation of the central shaft, so the position of the connecting rod 153 is more stable and the shaking will be reduced. The fixing on the side of the pressure mechanism 14 is done by clamping or hand support, which is not shown in the figure.

[0041] In another embodiment, the pressure mechanism 15 includes two connecting rods 153, each of which is connected to one of the elastic nets 16 by a connecting line. Each connecting rod 153 is hooked with a corresponding fixing hook 24, and each fixing hook 24 is connected with a corresponding connector 25. The end of the connector 25 away from the fixing hook 24 is connected to the outer shell 11. In this case, there are connecting rods 153 below both elastic nets 16. At this time, the position of the connecting rods 153 may wobble, but the connecting line saves more material. The stability of the connecting rods 153 on both sides is determined by the fixing hooks 24.

[0042] like Figure 4 As shown, one end of the connecting rod 153 is connected to a binding rope 154, and the other end of the connecting rod 153 away from the binding rope 154 is connected to a limiting protrusion 156. The other end of the binding rope 154 away from the connecting rod 153 is connected to a collar 155. The collar 155 is fitted onto the connecting rod 153 and locked inside the limiting protrusion 156. The binding rope 154 is one option; it does not have to be an elastic rope, as long as it can tightly bind one end of the valve bag being tested. In addition, the collar 155 fits onto the limiting protrusion 156, making it convenient to fix the position of the valve bag being tested.

[0043] like Figure 3 As shown, both ends of the curved cylinder 13 are connected to limit plates 18. The limit plates 18 also make it easier to place the valve bag to be tested on the curved cylinder 13 and prevent it from falling to the sides.

[0044] The valve bag to be tested is placed on the crank cylinder 13 and the elastic net 16. At this time, the valve bag to be tested simulates the process of carrying it on a person's shoulder. Several valve bags can be stacked on top of this valve bag to test the strength data obtained after the valve bags are stacked and pressure is applied. The electric cylinder / pneumatic device / hydraulic device inside the housing 11 is activated to give the inner rod 12 the power to lift upward. The inner rod 12 lifts the crank cylinder 13 to the center position of the valve bag to be tested. As the inner rod 12 continues to lift upward, the elastic net 16 on both sides will become elastic, allowing the crank cylinder 13 and the valve bag to be tested to have room to move when lifted upward by the inner rod 12.

[0045] When testing a scenario where the valve bag is manually transported to its location and then dropped, and to check whether the valve bag will break after being dropped from a certain height, one end of the valve bag is placed on the support ring 142, ensuring that the side of the valve bag does not exceed the limit plate 18 and the auxiliary plate 148. As the inner rod 12 is lifted upwards, and the weight and lifting force of the valve bag are used to test the strength at its center, the binding rope 154 is pressed against the upper surface of the valve bag. The collar 155 at one end of the binding rope 154 is fitted onto the limiting protrusion 156, thus restricting the position of the binding rope 154 and tightening and compressing the valve bag. Meanwhile, the insert plate 146 on the pressure plate 144 of the other side of the pressure mechanism 14 is inserted... The slot 145 and the wedge-shaped protrusion 147 on the clamping plate 144 push up one side of the clamping plate 144, causing the clamping plate 144 to tilt inward. One side of the clamping plate 144 tightens one side of the valve bag being tested, thus holding it very stably. After the side plate 22 and the torsion spring 23 are installed in the crank cylinder 13, a rebound force is applied to the crank cylinder 13 to flatten it. When the clamping mechanism 14, that is, the side of the valve bag being tested, does not move, the rebound force will give the other end of the valve bag being tested, that is, the lifting force of the live pressure mechanism 15, so that the loosening collar 155 fits the limiting protrusion 156. When the binding rope 154 does not tighten the valve bag being tested, the valve bag being tested will go up and then down, and be thrown towards the table, the ground or multiple columns (not shown in the diagram). At this time, the overall strength of the valve bag is tested.

[0046] When the test valve pocket is not being thrown out, the fixing hook 24 will hook the connecting rod 153. The connecting rod 153 is connected to the elastic net 16 either through the connecting line or through the side plate 152, the second side post 151 and the central shaft. At this time, the elastic net 16 can be stably pulled. When needed, the fixing hook 24 can be released to perform the throwing action of another embodiment. The throwing action is to simulate the situation of putting it down from the shoulder and onto the ground during actual handling.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
