Some of the blocks shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0031] This exemplary embodiment provides a pulley tensioning device for an embroidery machine frame, referring to Figure 1 As shown, the pulley tensioning device of the embroidery machine frame may include: a base 100 , a tensioner base 200 , a tensioner seat 300 , a tensioner adjusting block 400 and an adjusting member 500 .

[0032] Wherein, the base 100 is fixedly connected to the end of the guide rail of the embroidery machine frame;

[0033] The tensioner base 200 is fixedly connected to the base 100. A connection hole 201 is provided on the front of the tensioner base 200. Tensioner seats 300 are provided on two corresponding sides of the tensioner base 200. A pulley is provided between the two tensioner seats 300.

[0034] The tensioner adjustment block 400 is provided with a through hole 401 and an adjustment hole 402. The tensioner adjustment block 400 is connected to the connection hole 201 via a connector 403 passing through the through hole 401, and is fixedly connected to the front of the tensioner base 200.

[0035] The adjusting member 500 is threadedly connected to the adjusting hole 402 .

[0036] Through the above-mentioned pulley tensioning device of the embroidery machine frame, on the one hand, the tensioner adjusting block 400 is adjusted by tightening and loosening the adjusting member 500, so that the tensioner seat 300 can realize the tightening and loosening of the pulley through the adjustment of the tensioner adjusting block 400, thereby extending the life of the belt; on the other hand, the adjustment efficiency is improved by adjusting the tensioning force of the pulley through the tensioner adjusting block 400.

[0037] The following will refer to Figures 1 to 5 The various parts of the pulley tensioner of the embroidery machine frame in this exemplary embodiment will be described in more detail.

[0038] In one embodiment, the tensioner base 200 is fixedly connected to the base 100 via connecting screws 203.
