Description

Technical Field

[0001] The utility model relates to the technical field of valve bags, in particular to a drying mechanism for valve bags. Background Art

[0002] Valve bags are small bulk packaging containers with the advantages of convenience, neatness, and good sealing. In the production process of valve bags, they usually need to be pressed, dried, and hardened to ensure the quality and stability of the bag.

[0003] The traditional drying method is usually to introduce hot air into the valve bag. The higher temperature of the hot air will cause the moisture in the air in the bag to evaporate, thereby achieving the dehumidification effect. However, in actual operation, the process of introducing hot air into the valve bag can easily cause the problem of too fast air pressure balance in the valve bag. Too fast air pressure balance will affect the circulation of hot air in the valve bag, resulting in low efficiency, uneven drying and other problems. Therefore, it is particularly important to develop a more advanced, efficient and reliable valve bag drying mechanism. This drying mechanism can improve the drying effect and production efficiency of the valve bag, and ensure product quality and smooth production. Utility Model Content

[0004] The utility model aims to provide a valve bag drying mechanism to solve the problems of low efficiency and uneven drying of the valve bag drying mechanism in the prior art.

[0005] The utility model is realized by the following technical solutions:

[0006] A drying mechanism for a valve bag comprises a dryer body, a base is arranged on the outside of the dryer body, a coverless carrier shell for accommodating the valve bag is arranged above the base, a carrier air inlet pipe for inserting into the valve port of the valve bag is arranged on the side of the coverless carrier shell close to the dryer body, the carrier air inlet pipe penetrates the coverless carrier shell and a part of it protrudes in a direction away from the dryer body and is inserted into the valve port; a dryer air outlet is arranged on the outer surface of the dryer body on the side close to the coverless carrier shell, the dryer air outlet and the carrier air inlet pipe are located in the same horizontal direction and are inserted into the carrier air inlet pipe;

[0007] The coverless carrier shell is provided with a pressure plate inserted into the interior from directly above. After the pressure plate presses the inflated valve bag, it is pulled out from directly above the coverless carrier shell.

[0008] According to a further technical solution, carrier wheels are provided on the outer side of the lower surface of the uncovered carrier shell, and the carrier wheels are placed on the upper surface of the base. A telescopic rod a is provided between the dryer body and the uncovered carrier shell, and both sides of the telescopic rod a are respectively connected to the dryer body and the uncovered carrier shell.

[0009] A further technical solution is that a support rod is provided on the upper surface of the base away from the dryer body, a connecting arm is provided on the side of the support rod away from the base and close to the dryer body, a telescopic rod b is provided on the outer side of the lower surface of the connecting arm, and the pressure plate is arranged on the end of the telescopic rod b away from the connecting arm.

[0010] In this solution, the pressure plate applies external pressure to the valve bag in the carrier by extending the telescopic rod b downward, thereby breaking the air pressure balance in the valve bag, accelerating the hot air in the valve bag to carry moisture and further be discharged to the external space, thereby improving the drying efficiency.

[0011] Furthermore, the cross-sectional area of ​​the port of the carrier air inlet pipe close to the dryer body is greater than or equal to the cross-sectional area of ​​the port of the dryer air outlet away from the dryer body, so that the dryer air outlet can extend into the carrier air inlet pipe and accurately fill the hot air into the valve bag through the carrier air inlet pipe.

[0012] Furthermore, two concave slide grooves are provided on the upper surface of the base, and the carrier wheels are placed in the slide grooves. The slide grooves allow the carrier wheels to move in a fixed route and to move more accurately to under the pressure plate, making it easier for the pressure plate to accurately press the valve bag in the carrier, thereby causing the hot air in the valve bag to be further discharged into the external space.

[0013] Furthermore, the telescopic rod a is connected to the coverless carrier shell by screws, and the telescopic rod a is connected to the dryer body by welding.

[0014] Furthermore, the vehicle air inlet duct is integrally formed with the coverless vehicle shell.

[0015] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0016] The utility model discloses a drying mechanism of a valve bag, wherein a support rod is provided on the upper surface of the base away from one end of the dryer body, a connecting arm is provided on one end of the support rod away from the base and on one side close to the dryer body, a telescopic rod b is provided on the outer side of the lower surface of the connecting arm, and a pressure plate is connected to one end of the telescopic rod b away from the connecting arm, and the pressure plate applies external pressure to the valve bag in the carrier through the downward extension of the telescopic rod b, thereby breaking the air pressure balance in the valve bag, accelerating the hot air in the valve bag to carry moisture to the external space, and improving the drying efficiency; the cross-sectional area of ​​the port of the carrier air inlet pipe close to one end of the dryer body is greater than or equal to the cross-sectional area of ​​the port of the dryer outlet away from one end of the dryer body, so that the dryer outlet is convenient to extend into the carrier air inlet pipe and accurately fill the hot air into the valve bag through the carrier air inlet pipe, and at the same time avoids the valve port of the valve bag that discharges hot air after being applied with external pressure. It cannot be connected to the dryer outlet when the carrier approaches the dryer outlet, thereby causing the hot air to be unable to be filled into the valve bag again.

[0028] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0029] Example 1

[0030] refer to Figure 1-Figure 2 , a drying mechanism for a valve bag, comprising a dryer body 1, characterized in that a base 7 is provided on the outside of the dryer body 1, a coverless carrier shell 6 for accommodating the valve bag F1 is provided above the base 7, a carrier air inlet pipe 4 for inserting into the valve port of the valve bag F1 is provided on the side of the coverless carrier shell 6 close to the dryer body 1, the carrier air inlet pipe 4 passes through the coverless carrier shell 6 and a portion protrudes away from the dryer body 1 and is inserted into the valve port; a dryer air outlet 3 is provided on the outer surface of the dryer body 1 on the side close to the coverless carrier shell 6, the dryer air outlet 3 and the carrier air inlet pipe 4 are located in the same horizontal direction and are inserted into the carrier air inlet pipe 4.

[0031] The coverless carrier shell 6 is provided with a pressing plate 11 inserted into the interior from directly above. The pressing plate 11 is pulled out from directly above the coverless carrier shell 6 after pressing the inflated valve bag F1 .

[0032] A further technical solution is that a carrier wheel 5 is provided on the outer side of the lower surface of the uncovered carrier shell 6, and the carrier wheel 5 is placed on the upper surface of the base 7. A telescopic rod a2 is provided between the dryer body 1 and the uncovered carrier shell 6, and the two sides of the telescopic rod a2 are respectively connected to the dryer body 1 and the uncovered carrier shell 6.

[0033] A further technical solution is that a support rod 8 is provided on the upper surface of the base 7 away from the dryer body 1, a connecting arm 9 is provided on the side of the support rod 8 away from the end of the base 7 and close to the dryer body 1, a telescopic rod b10 is provided on the outer side of the lower surface of the connecting arm 9, and the pressure plate 11 is arranged on the end of the telescopic rod b10 away from the connecting arm 9.

[0034] In this solution, the pressure plate applies external pressure to the valve bag F1 in the carrier by extending the telescopic rod b10 downward, thereby breaking the air pressure balance in the valve bag, accelerating the hot air in the valve bag to carry moisture and further be discharged to the external space, thereby improving the drying efficiency.

[0035] Furthermore, the port cross-sectional area of ​​the carrier air inlet pipe 4 close to the dryer body 1 is greater than or equal to the port cross-sectional area of ​​the dryer air outlet 3 away from the dryer body 1, which facilitates the dryer air outlet 3 to extend into the carrier air inlet pipe 4 and accurately fill the hot air into the valve bag through the carrier air inlet pipe 4.

[0036] refer to Figure 4 Furthermore, two concave slide grooves 701 are provided on the upper surface of the base 7, and the carrier wheels 5 are placed in the slide grooves 701. The slide grooves 701 allow the carrier wheels 5 to move in a fixed route and to move more accurately to under the pressure plate 11, so that the pressure plate 11 can accurately press the valve bag in the carrier, thereby prompting the hot air in the valve bag to be further discharged to the external space.

[0037] refer to Figure 3 Furthermore, the telescopic rod a2 is connected to the coverless carrier housing 6 by a screw 12, and the telescopic rod a2 is connected to the dryer body 1 by welding.

[0038] refer to Figure 5-Figure 7 Furthermore, the vehicle air inlet duct 4 is integrally formed with the coverless vehicle shell 6 .

[0039] refer to Figure 8 , traditional technologies such as Figure 8 As shown, the valve bag is a bag with only one valve port, which serves as both an air inlet and an air outlet. When the hot air blower F2 blows gas into the valve port, the gas inflates the valve bag, and the air pressure gradually rises. When it rises to the outlet of the hot air blower F2, the pressures of the two are balanced, forming a pressure as shown in FIG. Figure 8 The reflux vortex shown is only formed at the valve port, and the gas inside the valve bag cannot circulate, and the internal water vapor cannot be taken out, which results in the inability to produce a high-efficiency drying effect.

[0040] refer to Figure 1-Figure 2 As shown in the figure, this solution adopts the technical concept of intermittent air supply and exhaust, in which the pressure plate presses down on the valve bag when the inflation is completed, thereby breaking the air pressure balance in the bag, forcing the gas inside the valve bag to be pressed out, and quickly letting the water vapor discharge. When inflated again, secondary drying is formed. The two cooperate with each other, inflate and exhaust in an intermittent mode, and the water vapor can be dried in only three to five cycles, which can greatly improve the drying efficiency in the hot air mode and avoid the problem that the gas inside the valve bag cannot form a cycle.

[0041] The method of using the utility model is:

[0042] When the drying mechanism of the valve bag is not started, the valve bag is placed in the shell of the uncovered carrier and the valve port of the valve bag is used to cover the carrier air inlet pipe. The telescopic rods a and b are in a retracted state, the uncovered carrier is close to the dryer body, and the dryer air outlet is aligned with the carrier air inlet pipe. The dryer body is started, and the hot air generated by the dryer body enters the valve bag through the dryer air outlet and the carrier air inlet pipe in turn and quickly fills the valve bag. When the valve bag is filled with hot air, the air pressure inside the valve bag is balanced, and the hot air circulation inside the valve bag is slowed down, and the drying effect is reduced. Then the telescopic rod a is gradually extended from the retracted state. The carrier is pushed to slide on the base until it moves under the pressure plate. The telescopic rod b gradually extends downward from the contracted state, and the pressure plate moves downward accordingly. After the pressure plate contacts the surface of the valve bag in the carrier, it continues to move, thereby applying external pressure to the valve bag and breaking the air pressure balance in the valve bag. During the pressure application process, moisture is discharged from the carrier's air inlet pipe to the external space along with the hot air; the telescopic rod b begins to contract, and the pressure plate moves up. Subsequently, the telescopic rod a contracts, the carrier moves and approaches the dryer body, and the carrier's air inlet pipe is aligned with and gradually approaches the dryer outlet; the above operations can then be repeated according to actual needs.
