Description

Technical Field

[0001] The utility model relates to the field of shaping machines, in particular to a guide rail with a buffer block. Background Art

[0002] The cloth conveying rails of the setting machine include the head curved rail, the middle rail and the tail rail. When the setting machine is working, the reducer drives the transmission shaft to rotate through the sprocket and the coupling. The transmission shaft drives the output shaft to rotate through the bevel gear in the gearbox. The sprocket mounted on the output shaft drives the conveyor chain to rotate. The conveyor chain is located in the cloth conveying rail and drives along the cloth conveying rail. The conveyor chain drives the fabric to pass through the oven to achieve the setting of the fabric.

[0003] However, the chain and guide rail will stretch due to the high temperature of the shaping machine. Long-term use will cause the chain to loosen and the high-speed operation in the guide rail will cause it to jump. The needle plate seat and needle plate installed on the chain will easily cause uneven needles on the needle plate when the shaped cloth is put on the needle plate, making the shaping quality of the product unstable. Utility Model Content

[0004] The utility model aims to provide a guide rail with a buffer block.

[0005] The innovation of the utility model is that a buffer block is added at the needle position of the machine head in the utility model, so as to reduce the gap between the guide rail and the chain ball when the needle is on the needle plate, and reduce the jumping of the needle plate.

[0006] To achieve the above-mentioned purpose of the utility model, the technical solution of the utility model is: a guide rail with a buffer block, including a guide rail head and a guide rail body, the guide rail head has a hook plate, and the inner side of the needle side of the guide rail head is provided with a buffer block that is connected to the hook plate.

[0007] Furthermore, an adjustment component is provided inside the buffer block for adjusting the buffer block to move perpendicularly to the length direction of the guide rail body, which is convenient for adjustment and can also move outward after the buffer block is worn.

[0008] Furthermore, a waist-shaped hole is provided on the buffer block, the waist-shaped hole is perpendicular to the length direction of the guide rail body, a limit screw is screwed into the waist-shaped hole, and the adjustment assembly includes a fixed block fixed on the guide rail head and an adjustment screw screwed on the fixed block, and the adjustment screw presses against the inner wall of the buffer block.

[0009] Furthermore, a notch is provided on the inner side wall of the buffer block, and the nut of the adjusting screw is located at the notch, thereby reducing the adjustment space.

[0010] Furthermore, the end of the buffer block located on one side of the hook plate is an arc-shaped head, which is not easy to be impacted.

[0011] Furthermore, a nut is screwed onto the adjusting screw, and the nut is located in the notch. The contact surface between the nut and the buffer block is large and is not easy to wear.

[0012] Furthermore, the buffer block is made of 45# heat-treated steel, which has good wear resistance.

[0013] The beneficial effects of the utility model are:

[0014] 1. In the utility model, a buffer block is added to the needle position of the machine head to reduce the gap between the guide rail and the chain ball when the needle is on the needle plate, thereby reducing the jumping of the needle plate.

[0015] 2. In the utility model, after the buffer block of the adjustment component is worn out at a later stage of use, the buffer block can be adjusted to move outwards. The buffer block is heat treated to increase its hardness, which can extend the service life of the buffer block and reduce the noise of the machine head. BRIEF DESCRIPTION OF THE DRAWINGS
