Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leather processing technology, specifically referring to a rotary drum feeding platform. Background Technology
[0002] In leather processing, the pre-impregnation, liming, tanning, and dyeing stages all require manual addition of chemicals to the drum. Due to the structure and process of the drum, there are protruding parts on both sides, resulting in a certain distance between the drum's feeding port and the platform. This poses a safety hazard to the workers adding chemicals, with the risk of stepping into a hole or falling from a height. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model creatively adopts a rotary drum feeding platform to at least partially solve the problems mentioned in the background art.
[0004] The technical solution adopted is as follows: This utility model embodiment proposes a rotating drum feeding platform, including a gatepost, a cylinder, a movable platform, a rotating drum, a fixed platform, and a safety door. The fixed platform is provided on one side of the rotating drum, and the gatepost is fixedly installed on the fixed platform. The safety door is installed on one side of the gatepost, and the movable platform is installed on the other side of the gatepost. The end of the movable platform is hinged to the lower part of the gatepost through a rotating shaft. The cylinder is provided on the outside of the gatepost, and the telescopic rod of the cylinder is connected to the middle of the movable platform.
[0005] The gateposts are provided in two positions, and the safety door is located between the two gateposts.
[0006] In addition, the safety door consists of two doors, which open towards the moving platform.
[0007] Furthermore, the minimum height of the two safety doors is higher than the height of the movable platform after it falls and opens.
[0008] Furthermore, the activity platform descends and opens, and the two safety doors open, with the two safety doors positioned on either side of the opened activity platform.
[0009] Furthermore, cylinders are respectively installed on the outer side of the two gateposts, and the telescopic rods of the two cylinders are connected to both sides of the movable platform. A first limit switch is provided on the upper part of the two gateposts, and a second limit switch is provided in the middle of the two gateposts.
[0010] The beneficial effects of this utility model by adopting the above structure are as follows: This invention features a movable platform that opens when lowered to fill the gap between the drum's feeding inlet and the fixed platform. This prevents workers from slipping and falling into the gap. The invention also includes safety doors. These doors prevent workers from entering while the drum is rotating and, when feeding, open to the sides of the movable platform, providing additional protection and further enhancing worker safety. This invention effectively solves the safety problem associated with feeding materials into the drum. Attached Figure Description

[0012] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation
[0013] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.
[0014] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments 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 limitations on the embodiments.
[0015] In some embodiments, like Figure 1As shown, a rotating drum feeding platform includes a gatepost 1, a cylinder 2, a movable platform 4, a fixed platform 6, a rotating shaft 7, and a safety door 8. The fixed platform 6 is provided on one side of the rotating drum 5, and the gatepost 1 is fixedly installed on the fixed platform 6. The safety door 8 is installed on one side of the gatepost 1, and the movable platform 4 is installed on the other side of the gatepost 1. The end of the movable platform 4 is hinged to the lower part of the gatepost 1 through the rotating shaft 7. The cylinder 2 is provided on the outside of the gatepost 1, and the telescopic rod 9 of the cylinder 2 is connected to the middle of the movable platform 4.
[0016] like Figure 2 and Figure 3 As shown, there are two gateposts 1, and the safety gate 8 is located between the two gateposts 1.
[0017] like Figure 2 and Figure 3 As shown, the safety door 8 consists of two doors, and the two safety doors 8 open towards the moving platform 4.
[0018] like Figure 1 and Figure 3 As shown, the minimum height of the two safety doors 8 is higher than the height of the movable platform 4 after it falls and opens.
[0019] The activity platform 4 descends and opens, and the two safety doors 8 open, located on both sides of the opened activity platform 4.
[0020] like Figure 1 and Figure 2 As shown, cylinders 2 are respectively installed on the outer side of the two gateposts 1. The telescopic rods 9 of the two cylinders 2 are connected to both sides of the movable platform 4. A first limit switch 3 is installed on the upper part of the two gateposts 1, and a second limit switch 10 is installed in the middle of the two gateposts 1.
[0021] The workflow is as follows: When material needs to be added to drum 5, stop drum 5 from rotating, open the front safety door, the first limit switch 3 on the gatepost 1 is activated, the two cylinders 2 are activated, causing the extension rods 9 of the two cylinders 2 to extend, and the movable platform 4 falls close to drum 5. The second limit switch 10 on the gatepost 1 is activated, disconnecting the operation control circuit of drum 5. No operation can cause the drum to move, increasing safety. Open the safety door 8. The two safety doors 8 are located on both sides of the movable platform 4 after opening, forming safety protection on both sides of the movable platform 4. Workers can step on the movable platform 4 to add material to drum 5. After the operation is completed, walk out of the safety door 8 and close the safety door 8 tightly. The first limit switch 3 on the gatepost 1 is activated, sending a reset signal to the control circuit. The two cylinders 2 are activated, causing the extension rods 9 of the two cylinders 2 to retract and lift the movable platform 4 upward. When the movable platform 4 is against the gatepost 1, the second limit switch 10 is activated to reset, restoring the operation control circuit of drum 5. At this time, drum 5 can be operated.
[0022] This invention features a movable platform 4, which opens when lowered to fill the gap between the feeding port of the drum 5 and the fixed platform 6. This prevents workers from slipping and falling into the gap. The invention also includes safety doors 8. These doors prevent workers from entering while the drum is rotating and, when feeding, open to the sides of the movable platform 4, providing additional protection and further enhancing the safety of workers. This invention solves the safety problem when feeding material into the drum 5.
[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
