Description

Technical Field

[0001] This utility model relates to the field of ton bag feeding technology, and more specifically, to a fixing device for ton bag feeding. Background Technology

[0002] A ton bag, also known as a bulk container, is a type of packaging bag or container used for holding and transporting large quantities of bulk materials. Because of its large capacity, it is usually measured in tons, hence the name "ton bag."

[0003] There are many types of ton bags. One type is a ton bag that is tied up at the top with a strap and has a discharge port at the bottom. Hooks are set at the four corners of the top of the ton bag. Currently, it is necessary to load materials into this type of ton bag. However, during the loading process, the top of the ton bag cannot be effectively extended, resulting in an uneven feeding. At the same time, the material cannot be evenly distributed in the ton bag. Therefore, the process of fixing the ton bag material needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a fixing device for ton packaging materials.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A fixing device for ton-packaged materials includes a hopper, a solenoid valve, a screw conveyor, a circular pipe, clamps, a placement plate, a frequency conversion vibration platform, a fixing plate, a spring, and an anti-detachment hook.

[0007] The solenoid valve is installed at the discharge port of the silo;

[0008] The feed hopper of the screw conveyor is connected to the discharge port of the silo, and the discharge port of the screw conveyor is flexibly connected to a round pipe.

[0009] The end of the round pipe is secured to the strapping of the ton bag with clamps;

[0010] The variable frequency vibration platform is mounted on the placement plate;

[0011] The fixing plates are symmetrically arranged on the placement plate, and each fixing plate is connected to two springs. The springs correspond one-to-one with the hooks of the ton bags, and one end of the spring is connected to an anti-detachment hook.

[0012] Furthermore, it also includes a placement platform, on which a weighing device electrically connected to the solenoid valve is installed, and a hopper is installed on the weighing device.

[0013] The above solution uses a weighing device to weigh the remaining material in the silo in real time, thereby achieving quantitative discharge and avoiding waste caused by excessive material filling.

[0014] Furthermore, one of the mounting plates is equipped with a voice prompt device that is electrically connected to the weighing device.

[0015] The above solution reduces the weight of the hopper by one ton and closes the solenoid valve while simultaneously controlling the voice prompt to issue a "discharge completed" command, thereby reminding staff to proceed with the subsequent hoisting and transfer of the ton bags, eliminating the need for constant human supervision.

[0016] Furthermore, the spring is a polyurethane spring.

[0017] The polyurethane springs described above have a long service life and excellent corrosion and heat resistance.

[0018] Furthermore, the circular tube is made of stainless steel.

[0019] The above solution uses a round tube that is lightweight and resistant to rust.

[0020] Furthermore, the feed inlet of the screw conveyor and the circular pipe are connected by a flexible hose.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Compared to existing technologies, this device can effectively extend and fix the top of the ton bag before it is filled, making the process of filling the flame retardant into the ton bag smoother. At the same time, the operation of the variable frequency vibration platform can effectively vibrate and compact the material already loaded into the ton bag, so that the material is evenly distributed in the ton bag. Thus, the filling and fixing process of the ton bag is effectively improved, and the effect is better. Attached Figure Description

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

[0028] like Figure 1 and Figure 2 As shown, a fixing device for ton-packaged materials includes a hopper 1, a solenoid valve 2, a screw conveyor 3, a circular pipe 4, clamps 5, a placement plate 6, a variable frequency vibration platform 7 (which belongs to the prior art and its working principle is not described), a fixing plate 8, a polyurethane spring 9, and an anti-detachment hook 10.

[0029] Solenoid valve 2 is installed at the discharge port of silo 1;

[0030] The feed hopper of the screw conveyor 3 is connected to the discharge port of the silo 1, and the discharge port of the screw conveyor 3 is flexibly connected to a round pipe 4 (specifically, the round pipe 4 is made of stainless steel, and the discharge port of the screw conveyor 3 and the round pipe 4 are connected by a flexible hose, which is not labeled in the figure).

[0031] The end of the round pipe 4 is secured to the ton bag's binding strap by clamp 5;

[0032] The variable frequency vibration platform 7 is mounted on the placement plate 6;

[0033] The fixing plates 8 are symmetrically arranged on the placement plate 6, and each fixing plate 8 is connected to two polyurethane springs 9. The polyurethane springs 9 correspond one-to-one with the hooks of the ton bag, and one end of the spring 9 is connected to an anti-detachment hook 10.

[0034] Further optimizations to the embodiments of this utility model, such as... Figure 1 As shown, it also includes a placement platform 11, on which a weighing device 12 electrically connected to the solenoid valve 2 is provided, and a hopper 1 is provided on the weighing device 12.

[0035] It should be noted that the solenoid valve 2, screw conveyor 3, and frequency conversion vibration platform 7 are all electrically connected to the controller, which is not shown in the figure.

[0036] The working process of this utility model is as follows:

[0037] Initially, the weighing device 12 is set to 0, and then sufficient material is stored in the silo 1. The material in this application is a flame retardant. After the material in the silo 1 is fully stored, the weight is 5 tons.

[0038] Then, several springs 9 are stretched sequentially so that the anti-detachment hooks 10 are connected one by one to the multiple hook straps on the ton bag. After all four anti-detachment hooks 10 are connected to the four hook straps, the springs 9 return to their original shape, thus extending and opening the top of the ton bag (as per the instruction manual). Figure 1 (as shown in the diagram), at the same time, the bottom of the ton bag is in contact with the frequency conversion vibration platform 7;

[0039] Then the controller controls the solenoid valve 2 to open and the screw conveyor 3 to work. Then the material enters the screw conveyor 3 and is transferred. Finally, it flows out from the discharge port of the screw conveyor 3 and is then injected into the ton bag through the round pipe 4.

[0040] Because the top of the ton bag is effectively extended and opened, the material loading process is smoother. At the same time as loading, the controller can also control the operation of the frequency conversion vibration platform 7 to achieve the compaction of the material in the ton bag. Then the material in the ton bag is evenly dispersed and will not form excessive accumulation in local areas.

[0041] As the loading process proceeds, the weight of the material in the hopper 1 will gradually decrease (it should be noted that since the discharge port of the screw conveyor 3 and the circular pipe 4 are connected by a flexible connection and the circular pipe 4 is relatively light, the influence of the variable frequency vibration platform 7 on the weighing during operation can be ignored). When the weight of the material weighed by the weighing device 12 is about to reach 4 tons (that is, the weight of the material loaded into a ton bag is 1 ton each time), the weighing device 12 will then send a feedback signal to the controller, and the controller will then control the solenoid valve 2 to close. This will achieve accurate quantitative loading and avoid overfilling and waste. When the solenoid valve 2 closes, the screw conveyor 3 will also stop working at the same time. At this time, the quantitative loading into the ton bag is completed.

[0042] After loading is completed, first release the clamp 5 between the upper sling of the ton bag and the round pipe 4, then tie the sling and then release the connection between the anti-detachment hook 10 and the hook strap in sequence. Then the subsequent hoisting and transfer process of the ton bag can be carried out. The hoisting and transfer of the ton bag is existing technology and will not be described in this application.

[0043] Compared to existing technologies, this device can effectively extend and fix the top of the ton bag before it is filled, making the process of filling the flame retardant into the ton bag smoother. At the same time, with the operation of the variable frequency vibration platform 7, the material already loaded into the ton bag can be effectively vibrated and compacted, so that the material is evenly distributed in the ton bag. Thus, the filling and fixing process of the ton bag is effectively improved, and the effect is better.

[0044] In some embodiments, such as Figure 1As shown, a voice prompt 13 electrically connected to the weighing device 12 is installed on one of the fixed plates 8. The voice prompt 13 is electrically connected to the controller. In this embodiment, while the hopper 1 is reduced by one ton and the controller controls the solenoid valve 2 to close, the controller also controls the voice prompt 13 to operate and issue the "discharge completed" command, thereby reminding the staff to carry out the subsequent hoisting and transfer process of the ton bag, without the need for a person to be on the side all the time.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
