Description

Technical Field

[0001] The utility model relates to the technical field of denim production, in particular to a denim drying mechanism. Background Art

[0002] Denim is a rough, cotton-like gauze cloth used to make jeans. Originally only blue, denim was originally used as a canvas, but now comes in many different colors to match different clothing. Research continues to change the appearance of denim through various chemical treatments and the use of effects such as flocking, embroidery and coatings. In addition, products developed include indigo-dyed jacquard fabrics, woven or knitted fabrics of linen and cotton, laser cutouts on denim, dull gloss patterns, and more personalized products.

[0003] Among them, in the denim production process, a drying mechanism is used to dry the washed and dyed denim to evaporate the moisture in the denim to meet the required production standards.

[0004] However, in actual use of the prior art, when a drying mechanism is used to dry the washed and dyed denim, the drying mechanism usually spreads the denim out and piles it inside the drying mechanism for rotary drying. However, when the denim is rotary dried, it is easy to cause the denim to be repeatedly rubbed inside the drying mechanism, resulting in wear and wrinkles, thereby affecting the subsequent production and processing of the denim. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: it comprises a main body bracket, both sides of the middle part of the main body bracket are rotatably connected with fixed rollers through a rotating shaft, limiting grooves are provided on both sides of the front and rear ends of the main body bracket, the inner wall of the limiting groove is movably connected with a fixing rod, the outer curved surface in the middle part of the fixing rod is rotatably connected with a clamping roller through a rotating shaft, the outer curved surfaces on both sides of the fixing rod are threadedly connected with fastening nuts for locking and fixing the fixing rod, a drying box for drying denim is fixedly installed in the middle part of the upper end of the main body bracket, a drying channel is provided on the upper end of the drying box, and the main Guide rollers are rotatably connected to the two sides of the middle upper end of the body bracket through bearing seats, a hair dryer is fixedly installed on the bottom of the drying channel, an electric heating rod is fixedly installed in the middle of the drying channel, and an air outlet is opened on the top of the drying channel; a limited straight slide groove is fixedly installed on the upper side wall of the rear end of the drying box, a driving motor is fixedly installed on the outer side wall of the limited straight slide groove, a driving screw is fixedly installed on the transmission shaft part on the inner side end of the driving motor, a slider is threadedly connected to the outer curved surface of the side end of the driving screw, and the lower end of the slider is rotatably connected to a water-absorbing roller for testing the humidity of denim through a pin shaft.

[0007] Preferably, a winding motor is fixedly installed on the outer side of the front top end of the main support, and a winding limit buckle is fixedly installed on the inner transmission part of the winding motor. The winding limit buckle is rotatably connected to the inner side of the front top end of the main support through a rotating shaft, and a winding roller for winding up the denim is fixedly installed on the inner side of the winding limit buckle.

[0008] Preferably, an unwinding limit buckle is rotatably connected to the inner side of the rear top end of the main frame via a rotating shaft, and an unwinding roller for unwinding the denim is fixedly installed on the inner side of the unwinding limit buckle.

[0009] Preferably, there are two fixed rollers, which are symmetrically distributed on both sides of the middle of the main bracket, and there are four limit grooves, with every two limit grooves forming a group, and the two groups of limit grooves are symmetrically distributed on both sides of the front and rear ends of the main bracket.

[0010] Preferably, there are two guide rollers, which are symmetrically distributed on both sides of the middle of the upper end of the main frame, and there are several hair dryers, which are symmetrically distributed on the bottom of the drying channel.

[0011] Preferably, both side ends of the transmission screw are rotatably connected to both sides of the inner wall of the limiting straight sliding groove through a rotating shaft, and both sides of the upper end of the sliding block are movably connected to the inner wall of the limiting straight sliding groove.

[0012] Preferably, the outer curved surface of the water-absorbing roller is bonded with water-absorbing cotton which rolls and absorbs the surface of the denim.

[0013] Compared with the prior art, the utility model has the following beneficial effects: when the hair dryer and the electric heating rod are controlled to be turned on, the hair dryer will blow the heat generated by the electric heating rod upwards, and when the hair dryer blows the heat generated by the electric heating rod upwards, the denim passing through the drying channel will be dried under the heat blown upwards, and at the same time, the hot air generated by the drying of the denim will be discharged through the air outlet, thereby achieving the effect of squeezing water out and squeezing and flattening the denim while drying it.

[0014] When the driving motor is controlled to be turned on, the driving motor will drive the transmission screw to rotate. When the transmission screw rotates, it will drive the slider to move straightly forward and backward along the inner wall of the limiting straight slide groove due to the force generated by the threaded connection with the outer curved surface of the side end of the transmission screw. When the slider moves straightly forward and backward, it will drive the water absorption roller to roll and absorb along the upper end of the dried denim, so that the drying effect of the denim can be judged by observing whether the outer surface of the water absorption roller after rolling and absorption contains moisture, thereby avoiding the problem of the denim being dried too long or too short in the drying channel.

The outer curved surfaces on both sides of the fixed rod 9 are threaded and useful The fixing rod 9 is locked and fixed with a fastening nut 11, so that when the fixing rod 9 is locked and fixed, the jeans can be squeezed to remove water and squeezed to be flattened through the clamping roller 10 and the fixing roller 7. At the same time, when the extrusion gap between the clamping roller 10 and the fixing roller 7 needs to be adjusted, the fastening nut 11 is loosened and the fixing rod 9 is pushed to move back and forth along the inner wall of the limiting groove 8 in a straight line, so that the jeans can be squeezed to remove water and squeezed to be flattened, and the extrusion gap between the clamping roller 10 and the fixing roller 7 can be adjusted.

[0024] A drying box 12 for drying denim is fixedly installed in the middle of the upper end of the main frame 1, and a drying channel 13 is opened through the upper end of the drying box 12. Guide rollers 14 are rotatably connected to both sides of the middle of the upper end of the main frame 1 through the bearing seat support, and there are two guide rollers 14, which are symmetrically distributed on both sides of the middle of the upper end of the main frame 1, so that the denim is guided to pass through the drying channel 13 for drying through the guide rollers 14.

When the driving screw 20 rotates, the slider 21 will be driven to move straightly forward and backward along the inner wall of the limiting straight slide groove 18 due to the force generated by the threaded connection with the outer curved surface of the side end of the driving screw 20. When the slider 21 moves straightly forward and backward, the water-absorbing roller 22 will be driven to roll and absorb along the upper end of the dried denim. Therefore, the drying effect of the denim can be judged by observing whether the outer surface of the water-absorbing roller 22 after rolling and absorption contains moisture, thereby avoiding the problem of the denim being dried too long or too short in the drying channel 13.
