Description

Technical Field

[0001] The utility model relates to the field of shaping machines, in particular to a needle plate seat chain structure which is not prone to oil throwing. Background Art

[0002] CN217078054U discloses "a sun star needle plate seat with bottom oil leakage prevention". The needle plate seat is provided with an oil leakage groove for oiling. Now the printing and dyeing industry pursues efficiency and energy saving. In the oiling method, when the setting machine is running at high speed during normal production, the oil will be blown onto the cloth surface under the action of circulating wind when entering the drying room, resulting in defective cloth. Utility Model Content

[0003] The utility model aims to provide a needle plate seat chain structure which is not easy to throw oil.

[0004] The innovation of the utility model is that the oil leakage hole originally located on the needle plate seat is changed into a bottom oil guide groove in the utility model, and the oil falls on the upper pressing plate above the upper pressing plate. Since the needle plate seat blocks this place, the oil will not be thrown out.

[0005] In order to achieve the above utility model purpose, the technical solution of the utility model is:

[0006] A needle plate seat chain structure which is not easy to throw oil off comprises a chain and a needle plate seat, wherein the needle plate seat is fixed on an upper pressure plate of the chain, and a bottom oil guide groove is provided at the bottom of the needle plate seat located on one side of the chain.

[0007] Furthermore, the needle plate seat includes a chain fixing seat and a needle plate fixing seat with an L-shaped cross-section connected to the chain fixing seat, the chain fixing seat is provided with a plurality of chain connecting holes, and the bottom surface of the chain fixing seat is provided with a bottom oil baffle plate that supports the upper pressure plate located on the side of the needle plate fixing seat.

[0008] Furthermore, a clearance opening is provided on the bottom surface of the chain fixing seat at the contact point between the bottom oil baffle plate and the upper pressing plate to prevent the bottom oil baffle plate from being processed inadequately and the bottom oil baffle plate and the upper pressing plate side edges from being not tightly pressed together, thereby preventing oil leakage from this point.

[0009] Furthermore, the upper pressing plate is provided with a top oil guide groove corresponding to the bottom oil guide groove, so as to prevent the oil from flowing out of the upper pressing plate and facilitate the oil to enter the chain ball and the guide rail.

[0010] Furthermore, the upper pressing plate is provided with chamfers at two corners on one side away from the needle plate seat. Adding chamfers on the chain cover, the shaping machine is made of guide rails of different lengths. Because the shaping machine is too long, the splicing gap will be on the same horizontal line during the splicing process, and there will be slight errors. When the chain runs at high speed (a shaping machine has 600 to 700 sets of chains running on one side), the chain will jump and the resistance will increase, causing the shaping machine reducer power to increase. Adding chamfers on the chain cover can reduce resistance and reducer energy consumption.

[0011] The beneficial effects of the utility model are:

[0012] In the utility model, the oil leakage hole originally located on the needle plate seat is changed into a bottom oil guide groove, and the oil falls on the upper pressing plate above the upper pressing plate. Since the needle plate seat blocks this place, the oil will not be thrown out.

[0013] In the utility model, adding chamfers to the chain cover plate can reduce resistance and energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0017] Embodiment 1: as Figure 1 , 2 As shown, a needle plate seat chain structure that is not easy to throw oil includes a chain 1 and a needle plate seat 2. The needle plate seat 2 is fixed on the upper pressure plate 1.1 of the chain 1. The bottom of the needle plate seat 2 located on one side of the chain is provided with a bottom oil guide groove 3, and the upper pressure plate 1.1 is provided with a top oil guide groove 1.11 corresponding to the bottom oil guide groove 3. Chamfers 1.12 are provided at two corners of the upper pressure plate 1.1 away from the needle plate seat 2.

[0018] The needle plate seat 2 includes a chain fixing seat 2.1 and a needle plate fixing seat 2.2 with an L-shaped cross-section connected to the chain fixing seat 2.1. The chain fixing seat 2.1 is provided with a plurality of chain connecting holes 2.11. The bottom surface of the chain fixing seat 2.1 is provided with a bottom oil baffle plate 4 that supports the upper pressure plate 1.1 located on the side of the needle plate fixing seat 2.2.

[0019] The bottom surface of the chain fixing seat 2.1 is provided with a clearance opening 2.3 at the contact point between the bottom oil baffle plate 4 and the upper pressure plate 1.1.

[0020] During operation: oil drops onto the upper pressure plate 1.1 and flows from the top oil guide groove 1.11 into the bottom oil guide groove 3 to lubricate the ball bearings and the chain.

[0021] The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
