AI Technical Summary
Traditional TDO tracks cannot completely prevent wear during sheet production due to the lubricating oil, resulting in oil accumulation that is splashed onto the sheet surface or the ground, affecting sheet quality and making cleaning difficult.
An oil-blocking device is installed on the chain clamp track, including a first bend, a second bend, a first baffle, and a second baffle, forming an L-shaped structure. These are fixed on the chain clamp track respectively, and the upper and lower air outlets and the baffle structure prevent oil from being splashed onto the sheet or the ground.
It effectively prevents oil stains from being directly thrown onto the sheet and blown onto the sheet by the air nozzle, ensuring the quality of the sheet, reducing the difficulty of cleaning oil stains on the ground, and improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sheet production technology, and in particular relates to an oil-blocking device for a chain clamp track for sheet stretching. Background Technology
[0002] During sheet production, the sheets need to be stretched. In order to ensure the service life of the bottom chain and copper plate, the bottom chain of a traditional TDO track is sprayed with lubricating oil. However, because the hardness of the copper plate is much lower than that of the chain, the oil spraying cannot completely guarantee that the copper plate will not wear out. As a result, copper powder will be ground out. The copper powder mixed with the oil will affect the discharge of lubricating oil and thus accumulate in the track. Under these circumstances, the oil stains will increase and will be thrown onto the surface of the sheet as the track runs, or blown onto the surface of the sheet by the fan, or fall to the ground.
[0003] Traditional TDO tracks lack oil-proofing measures, leading to easy oil spillage on the ground. During foreign object detection, the sheet surface is often heavily soiled with oil, partly due to oil splashing from the chain clamp track, and partly because the fan outlets are located directly above and below the chain clamps, causing excessive airflow that can blow oil onto the sheet. Therefore, existing TDO systems suffer from sheet quality defects due to oil splashing from the chain clamp base during operation. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide an oil-blocking device for a chain clamp track for sheet stretching, which can be equipped with an oil-blocking plate to isolate most of the oil stains from being thrown onto the sheet in multiple ways.
[0005] The present invention is implemented as follows:
[0006] An oil-blocking device for a sheet-stretched chain clamp track, wherein air outlets for blowing air in a vertical direction are respectively provided above and below the chain clamp track, and the oil-blocking device is disposed on the chain clamp track, comprising: a first bending part, a second bending part, a first baffle and a second baffle, the first baffle and the second baffle are integrally formed and are L-shaped, the right end of the second baffle is connected to the lower end of the first baffle, the first baffle is vertically distributed in the space between the chain clamp track and the sheet, the second baffle is disposed below the chain clamp track, placed horizontally, and located between the chain clamp track and the lower air outlet, the first baffle and the second baffle are respectively fixed on the chain clamp track, and a distance is maintained between the baffle and the chain clamp track, the first bending part is connected and fixed to the upper end of the first baffle and bends inward to the chain clamp track, and the second bending part is connected to the left end of the second baffle and bends outward to the chain clamp track.
[0007] The bending angle of the first bending part is 45 degrees.
[0008] The bending angle of the second bending part is 40 degrees.
[0009] The upper end of the first bend is close to the horizontal plane where the sheet is located.
[0010] This utility model embodiment installs an oil-blocking device on the chain clamp track. Oil-blocking plates are installed at the bottom of the chain clamp track and between the chain clamp track and the sheet. The bottom oil-blocking plate prevents oil from falling to the ground, and the oil-blocking plate between the chain clamp track and the sheet prevents oil from being blown onto the sheet. By adding oil-blocking plates to the original structure, it can effectively prevent oil from being directly thrown onto the sheet and indirectly blown onto the sheet by the air nozzle, ensuring the quality of sheet production and reducing the difficulty of cleaning oil stains on the ground. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the oil-blocking device for the chain clamp track of sheet stretching according to this utility model. Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:
[0014] like Figure 1 As shown, an oil-blocking device for a sheet-stretched chain clamp track is provided. Air outlets for blowing air in the up-down direction are respectively provided above and below the chain clamp track 6. The oil-blocking device is installed on the chain clamp track and includes: a first bending part 2, a second bending part 5, a first baffle 3, and a second baffle 4. The first baffle and the second baffle are integrally formed, forming an L-shape. The right end of the second baffle is connected to the lower end of the first baffle. The first baffle is vertically distributed in the space between the chain clamp track and the sheet 1. The second baffle is positioned below the chain clamp track, horizontally placed, between the chain clamp track and the lower air outlet. Both the first and second baffles are fixed on the chain clamp track, maintaining a distance between the baffles and the chain clamp track. The first bending part is connected and fixed to the upper end of the first baffle, bending inwards towards the chain clamp track. The second bending part is connected to the left end of the second baffle, bending outwards towards the chain clamp track.
[0015] In the figure, the bending angle of the first bend is 45 degrees, which helps to prevent oil stains blown up from the upper air outlet from adhering to the sheet and provides better isolation.
[0016] In the figure, the second bend has a bending angle of 40 degrees, which helps to collect the oil in the oil-blocking device.
[0017] In the figure, the upper end of the first bend is close to the horizontal plane where the sheet is located, so that the sheet has a better oil-proof effect.
[0018] This utility model embodiment installs an oil-blocking device on the chain clamp track. Oil-blocking plates are installed at the bottom of the chain clamp track and between the chain clamp track and the sheet. The bottom oil-blocking plate prevents oil from falling to the ground, and the oil-blocking plate between the chain clamp track and the sheet prevents oil from being blown onto the sheet. By adding oil-blocking plates to the original structure, it can effectively prevent oil from being directly thrown onto the sheet and indirectly blown onto the sheet by the air nozzle, ensuring the quality of sheet production and reducing the difficulty of cleaning oil stains on the ground.
[0019] In this embodiment of the invention, a TDO oil baffle is designed according to production needs. A baffle with a 45° top edge is added to the inner side of the TDO track. The baffle is fixed to the inner wall of the track with bolts while being fitted with nuts, increasing the gap to facilitate the flow of oil. The baffle extends to the bottom, bends, and then extends to the outer wall of the track, bending upwards at a 40° angle to block the air nozzles and prevent oil from falling onto the ground and causing pollution. Furthermore, wool felt can be added to the bottom plane of the baffle to absorb oil and facilitate collection and cleaning.
[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
