Description

Technical Field

[0001] The utility model relates to the technical field of washing machine manufacturing, in particular to a local automatic tensioning mechanism for an ironing belt. Background Art

[0002] The ironing machine is used to quickly iron and dry fabrics in large laundry factories, hospitals, hotels, textile factories, printing and dyeing factories, campuses, national armies and other collective places. When the ironing machine is working, the fabric to be ironed moves in sequence along the surfaces of multiple steam-filled drying drums under the traction of the ironing belt. While moving, the fabric is quickly ironed and dried by relying on the temperature of the drying drum surface. Due to long-term operation under high temperature, the ironing belt will slowly shrink. At this time, it is necessary to adjust the tension of the ironing belt in time to ensure the ironing quality.

[0003] Existing ironing machines such as Figure 1 As shown in the figure, cylinders or springs are mostly used to uniformly tension or relax the ironing belts wound around the same drying drum. Since it is impossible for every piece of ironed linen to be covered by the entire ironing belt, the linens are usually pulled forward by the ironing belt near the middle of the drying drum. This causes the ironing belt in the middle to be in contact with the wet linens for a long time, while the ironing belts on both sides of the drying drum cannot touch the linens, so the ironing belts shrink differently. This tensioning method will cause:

[0004] 1. When the ironing belt shrinks inconsistently, it will cause the ironing belt to be inconsistent in tightness, deviate and wear.

[0005] 2. The inconsistent tightness of the ironing belt directly affects the ironing quality. Utility Model Content

[0006] The utility model aims to provide a local automatic tensioning mechanism for an ironing belt to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: a local automatic tensioning mechanism for an ironing belt, comprising a box wall panel, a beam is fixedly connected to the inner side of the box wall panel, a fixing plate is fixedly connected to the top of the beam symmetrically, and a local tensioning mechanism is arranged on the top of the fixing plate;

[0008] The local tensioning mechanism includes a guide rod, which is symmetrically arranged on the left side of the top of the fixed plate. A limiting gasket is symmetrically sleeved on the surface of the guide rod, and a tensioning spring is sleeved on the surface of the guide rod. An adjusting nut is arranged on the surface of the guide rod near the bottom end. A roller bracket is fixedly connected to the surface of the guide rod near the bottom end. A fixing nut is arranged on the bottom end of the guide rod surface. A core shaft is arranged on the left side of the roller bracket. A shaft retaining spring is clamped on the surface of the core shaft near both sides, and a roller is fixedly connected to the surface of the core shaft.

[0009] Preferably, a hole matching the guide rod is opened on the top of the fixing plate, and the surface of the guide rod passes through and is slidably connected in the hole.

[0010] Preferably, the top end of the tensioning spring is fixedly connected to the bottom of a limiting gasket on the surface of the guide rod near the top end, and the bottom end of the tensioning spring is fixedly connected to the top of the limiting gasket on the surface of the guide rod.

[0011] Preferably, a thread groove matching the adjusting nut is formed on the surface of the guide rod near the bottom end, and the adjusting nut is threadedly connected to the surface of the guide rod through the thread groove.

[0012] Preferably, a thread groove matching the fixing nut is provided on the surface of the guide rod near the bottom end, and the fixing nut is threadedly connected to the surface of the guide rod near the bottom end through the thread groove.

[0013] Preferably, holes matching the core shaft are provided on the left and right sides of the roller bracket, and the surface of the core shaft passes through and is rotatably connected to the holes.

[0014] Preferably, there are five groups of local tensioning mechanisms, which are equidistantly arranged on the top of the fixed plate.

[0015] Compared with the prior art, the utility model provides a local automatic tensioning mechanism for an ironing belt, which has the following beneficial effects:

[0016] 1. The local automatic tensioning mechanism of the ironing belt passes the ironing belt from under the roller. When the ironing machine is working, since the ironing belts on both sides cannot contact the linens for a long time, the contraction will be different from that in the middle, which will make the ironing belts on both sides too loose or too tight. When the ironing belt is too loose, the tensioning spring will press the roller to move in the direction of loosening the ironing belt. When the force pressing the ironing belt is consistent with the preset force, the tightness of the ironing belt is consistent with that in the middle. When the ironing belt is stretched, due to the action of the tensioning spring, the guide rod moves downward, so that the roller always maintains a certain pre-tightening force with the ironing belt, and the ironing belt maintains appropriate tightness. When the ironing belt contracts, the guide rod moves upward under the action of the tensioning spring, and finally the pre-tightening force of the roller and the ironing belt is consistent, so that the tightness of the ironing belt is appropriate. The guide rod is fixed to the roller bracket through a fixing nut, and the tensioning spring is sleeved on the guide rod through two upper and lower limit washers, and the pre-tightening force is adjusted by adjusting the nut.
