Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco conveying equipment, and in particular relates to a conveyor belt lower hopper sealing device. Background Art

[0002] The belt conveyor in the silk-making workshop mainly serves to transport materials. Due to the setting of the process path, the height difference between the lower hopper and the feed belt of some conveyor belts is large. When the materials fall onto the feed belt, airflow is easily generated. Therefore, a hanging curtain is installed at the drop port.

[0003] Since the material outlet of the lower hopper faces the center of the downstream conveyor belt, there is a certain gap between it and the downstream conveyor belt wall. During the production process, some materials will accumulate in the gap and cannot be transported, resulting in material accumulation; during the material transportation process, some smoke and debris will overflow from the conveyor belt wall under the action of the falling airflow, resulting in material leakage. After the batch is completed, if it is not cleaned up in time, it is easy to cause quality accidents such as mixing and leakage, which will cause quality risks and affect the on-site production environment.

[0026] like Figure 1-2 As shown, a conveyor belt lower hopper sealing device of the utility model comprises a bracket 1, and the bracket 1 is provided in two and symmetrically arranged on both sides of the conveyor belt.

[0027] In this embodiment, each bracket 1 includes two vertical connecting rods 11 and a horizontal connecting rod 12. The two vertical connecting rods 11 are fixedly mounted on both ends of the mounting plate on one side of the conveyor belt. Both ends of the horizontal connecting rod 12 are respectively connected to the vertical connecting rod 11. An adjusting disk 13 is fixedly connected to the top of the bracket 1.

[0028] An annular adjustment hole 131 is provided on the adjustment disk 13 . The horizontal connecting rod 12 is a telescopic rod. An adjustment screw is fixedly connected to the horizontal connecting rod 12 . The adjustment screw passes through the annular adjustment hole 131 . A nut 14 is threaded on the adjustment screw.

[0029] When the bracket 1 is installed to match the conveyor belt, first fix the two vertical connecting rods 11 of one bracket 1 on the mounting plate on one side of the conveyor belt, rotatably connect one end of the horizontal connecting rod 12 and a vertical connecting rod 11, adjust the length of the horizontal connecting rod 12 so that the adjusting screw on the horizontal connecting rod 12 is located in the annular adjusting hole 131 in the adjusting disk 13, further adjust so that the horizontal connecting rod 12 is set parallel to the upper surface of the conveyor belt body, tighten the nut 14, and fix the horizontal connecting rod 12.

[0030] Furthermore, in order to facilitate the installation of the bracket 1, the vertical connecting rod 11 can also be a telescopic rod. The vertical connecting rod 11 can include an inner rod and an outer rod, the inner rod is sleeved in the outer rod, a plurality of mounting holes are opened along the length direction of the inner rod, and an adjustment screw is provided on the outer rod, and the adjustment screw passes through the mounting hole. The position of the inner rod is used to match different mounting holes with the adjustment screw, so as to adjust the length of the vertical connecting rod 11.

[0031] In this embodiment, a guide ramp 3 is fixedly mounted on the bracket 1. The guide ramp 3 is provided in two pieces, which are respectively located on both sides of the conveyor belt, and the inclined surfaces of the guide ramp 3 are inclined inward from top to bottom toward the upper surface of the belt body, and the bottom end of the guide ramp 3 is in contact with the conveyor belt. When unloading, the tobacco shreds fly onto the guide ramp 3, and are transported back to the belt body along the guide ramp 3, so that the materials are collected, and the material loss is reduced. The structure is simple and the practicability is strong.

[0032] In this embodiment, a seal 2 is also provided on the bracket 1, and the seal 2 is used to close the gap between the mounting plate and the bracket 1 when the material is conveyed from the discharge hopper to the conveyor belt. The seal 2 is a hanging curtain, and the top end of the hanging curtain is fixed to the bracket 1. The hanging curtain is tilted, and the tilting direction is the same as the tilting direction of the material guide inclined plate 3, and the lower end of the hanging curtain is in contact with the material guide inclined plate 3. The seal 2 is set as a flexible hanging curtain. On the one hand, when the material is discharged from the discharge port to the conveyor belt, a material discharge airflow is generated. Under the action of the material discharge airflow, the hanging curtain is tightly attached to the material guide inclined plate 3, and the sealing effect is good to prevent the material from falling into the gap on both sides of the conveyor belt; on the other hand, because the hanging curtain is made of flexible material, it is convenient to carry out maintenance and cleaning after production is completed.

[0033] In this embodiment, a guide plate 4 is provided on the support 1 for blocking the airflow generated when the lower hopper conveys tobacco. The guide plates 4 are provided in two pieces, which are respectively located on both sides of the lower hopper. The guide plates 4 are provided above the belt body and on the inner side of the sealing member 2. When the material is discharged, the tobacco material flow is output to the conveyor belt, generating airflow, which diffuses to both sides of the conveyor belt, passes through the guide inclined plate 3 and the hanging curtain to reach the baffle plate. Under the blocking effect of the baffle plate, the airflow flows to the middle of the conveyor belt, thereby reducing the material loss caused by the airflow carrying away the tobacco.

[0034] The principles of this application are:

[0035] The lower hopper delivers tobacco to the conveyor belt, and the material flows to the middle of the upper surface of the belt body, generating airflow, which presses the hanging curtain against the guide inclined plate 3. The airflow passes through the guide inclined plate 3 and the hanging curtain and reaches the guide plate 4. Under the blocking effect of the guide plate 4, the airflow flows to the middle of the belt body. The tobacco material carried by the airflow falls on the guide inclined plate 3 and the hanging curtain, slides back to the belt body, or flows back to the belt body under the blocking effect of the guide plate 4.
