Technical Field

[0001] This utility model relates to the field of flour transportation technology, and in particular to an exhaust device for transporting bagged flour. Background Technology

[0002] Flour is a powdery substance made from milled wheat. Based on its protein content, flour can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. After production, flour needs to be bagged for transportation and sale; currently, automated equipment is being used for loading bagged flour onto trucks.

[0003] Automated equipment for palletizing and loading bagged flour results in less compression compared to manual loading. However, some flour bags may retain a lot of air that cannot escape, leading to loose palletizing and affecting the stability of the flour stack. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where a large amount of residual air remains inside the flour stack during automated loading, affecting the stability of the flour stack. This invention provides an exhaust device for transporting bagged flour.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A degassing device for transporting bagged flour includes a conveyor belt, a frame on the outer side of the conveyor belt, and multiple degassing rollers above the conveyor belt. Each degassing roller includes a left rotating disk and a right rotating disk on both sides of the conveyor belt, and multiple rollers connecting them. The rollers are evenly distributed in a ring between the two rotating disks. A hollow shaft is located at the center of the left rotating disk, and a bearing mounted on the frame is fitted onto the outer side of the hollow shaft. The right rotating disk is connected to a drive assembly for rotating it. An air extraction pipe is located inside each of the rollers, with multiple suction holes near the conveyor belt. One end of the air extraction pipe extends through the hollow shaft and connects to an air extraction device. A mounting bracket is provided on the frame for fixing the air extraction pipe.

[0007] Preferably, the rollers are rotatably mounted between the left and right rotating disks.

[0008] Preferably, the air extraction pipe is positioned close to the bottom of the roller's rotation path.

[0009] Preferably, the conveyor belt is evenly and densely covered with ventilation holes, and multiple anti-slip strips are evenly provided on the outer surface of the conveyor belt perpendicular to its direction of movement.

[0010] More preferably, the inner side of the conveyor belt is provided with multiple support rollers close to the upper layer of the conveyor belt, and both sides of the support rollers are rotatably mounted on the frame via rotating seats.

[0011] More preferably, the inner side of the conveyor belt is provided with multiple air extraction pipes below the support roller shaft, and the air extraction holes on the air extraction pipes are arranged on the side close to the support roller shaft.

[0012] Preferably, the drive assembly includes a motor fixedly mounted on the frame, a synchronous pulley coaxially mounted on the motor output end and the right rotating disk, and a synchronous belt disposed on the outer side of the multiple synchronous pulleys.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the design of multiple exhaust rollers, in conjunction with roller pressure rods, stabilizes the bagged flour by roller pressure and exhausts air, reduces residual air, ensures good exhaust effect, and facilitates the stacking and loading of bagged flour.

[0015] 2. In this utility model, the design of the exhaust pipe absorbs the flour dust that escapes during the roller extrusion process, ensuring a good dust removal effect and guaranteeing the cleanliness and safety of the production environment.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A ventilation device for transporting bagged flour includes a conveyor belt 1, a frame 2 on the outside of the conveyor belt 1, and multiple ventilation rollers 3 on the top of the conveyor belt 1. The bagged flour is transported by the conveyor belt 1 and the ventilation rollers 3 are used to roll and press the flour to facilitate the stacking and loading of the flour.

[0026] The exhaust roller 3 includes a left rotating disk 32 and a right rotating disk 33 arranged on both sides of the conveyor belt 1, and multiple rollers 31 connected between them. The rollers 31 are evenly distributed in a ring between the two rotating disks. The left rotating disk 32 has a hollow rotating shaft 321 at its axis, and a bearing 322 mounted on the frame 2 is fitted on the outside of the hollow rotating shaft 321. The right rotating disk 33 is connected to a drive assembly 35 for rotating it. The drive assembly 35 drives the exhaust roller 3 to rotate, which, together with the rollers 31, compresses the flour bag to expel the residual air in the flour bag, making the flour bag flat for loading. While rolling, the rotating disks on both sides can also provide lateral support to the flour bag, preventing air from accumulating on both sides and affecting the exhaust effect, ensuring good exhaust effect of the flour bag for stacking. The design of using multiple exhaust rollers 3 can avoid the problem of residual air in the flour bag when a single exhaust roller 3 is rolling. By rolling multiple exhaust rollers 3 simultaneously, the air in the flour bag can be effectively expelled. To ensure the rolling effect of multiple exhaust rollers 3, different rotating disk sizes can be set so that the movement path of the roller rod 31 is closer, ensuring a good exhaust effect on smaller flour bags.

[0027] Multiple rollers 31 are equipped with suction pipes 4 on their inner sides. Multiple suction holes 42 are opened on the suction pipe 4 near the conveyor belt 1. One end of the suction pipe 4 extends through a hollow rotating shaft 321 and connects to a suction device. The frame 2 is equipped with a fixing bracket 41 for fixing the suction pipe 4. The fixing bracket 41 ensures the stability of the suction pipe 4. When venting the flour, the suction holes 42 on the suction pipe 4 remove any flour that may escape during the venting process, ensuring the cleanliness and safety of the vented flour.

[0028] Based on the above technical solution, before the flour is stacked and loaded onto the truck, the bagged flour is placed on the conveyor belt 1 for conveying. The flour bags are rolled and vented by the exhaust rollers 3 set on the conveyor belt 1. The design of multiple roller bars 31 avoids excessive squeezing pressure on the flour bags. At the same time, the multiple exhaust rollers 3 ensure a good rolling and venting effect, ensuring good stacking effect and stacking efficiency of the bagged flour.

[0029] In this technical solution, such as Figure 1-6 As shown, the rollers 31 are rotatably mounted between the left rotating disk 32 and the right rotating disk 33. This reduces friction between the rollers 31 and the flour bags, preventing damage to the flour bags and ensuring good flour quality upon leaving the factory.

[0030] In this technical solution, such as Figure 1-6 As shown, the exhaust pipe 4 is positioned close to the bottom of the rotation path of the roller 31. This ensures effective absorption of loose flour dust and guarantees a clean exhaust environment.

[0031] In this technical solution, such as Figure 1-6 As shown, the conveyor belt 1 is evenly and densely covered with ventilation holes 11, and multiple anti-slip strips 12 are evenly arranged on the outer surface of the conveyor belt 1 perpendicular to its direction of movement. The anti-slip strips 12 ensure stable conveying of flour.

[0032] In this technical solution, such as Figure 1-6 As shown, multiple support rollers 5 are provided on the inner side of the conveyor belt 1, close to the upper layer. Both sides of the support rollers 5 are rotatably mounted on the frame 2 via rotating seats. The support rollers 5 support the flour on the conveyor belt 1, and in conjunction with the rolling pressure of the exhaust rollers 3, ensure stable pressure and exhaust of the flour bags.

[0033] In this technical solution, such as Figure 1-6 As shown, multiple suction pipes 4 are provided on the inner side of the conveyor belt 1 below the support roller shaft 5, and the suction holes 42 on the suction pipes 4 are arranged on the side close to the support roller shaft 5. The suction pipes 4 remove flour dust that escapes through the vent holes 11, ensuring the safety of the production environment.

[0034] In this technical solution, such as Figure 1-5 As shown, the drive assembly 35 includes a motor 353 fixedly mounted on the frame 2, a synchronous pulley 351 coaxially mounted on the output end of the motor 353 and the right rotating disk 33, and a synchronous belt 352 disposed on the outer side of the multiple synchronous pulleys 351. The motor 353, in conjunction with the synchronous belt 352 and the synchronous pulleys 351, drives the exhaust roller 3 to rotate, ensuring stable roller pressure and exhaust of the flour.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
