DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1: Figure 1-6 As shown, an oven for a hot air stentering machine comprises a base 1, a blast assembly, an outer cover 11 and a control panel, wherein the outer cover 11 is arranged at the upper end of the base 1, the blast assembly is arranged between the base 1 and the outer cover 11 and is located inside the outer cover 11, the left and right ends of the outer cover 11 are provided with cloth inlets and the front side is provided with a middle door 12, and a drafting mechanism is arranged inside the outer cover 11; The drafting mechanism includes a transmission assembly, an accessory chain 2 and a plurality of cloth pullers. The transmission assembly is arranged in the outer cover 11. The accessory chains 2 are arranged in two groups and are arranged in the transmission assembly in a front-to-back distribution. The accessory chains 2 are in a runway-like structure as a whole. The plurality of cloth pullers are symmetrically distributed between the two accessory chains 2. The cloth puller includes a lower clamping plate 3, an upper clamping plate 31 and a flipper. The lower clamping plate 3 is connected to the accessory chain 2. The upper clamping plate 31 is rotatably arranged on the upper end of the lower clamping plate 3 through a connecting ear and the rotation point is located on one side of the accessory chain 2. The flipper is arranged between the lower clamping plate 3 and the upper clamping plate 31.

[0021] When the cloth is subjected to hot air tentering processing, the cloth is pulled by an external pulling device and passes through the outer cover 11, wherein the outer cover 11 cooperates with the base 1 to form a closed space, and a high temperature environment can be formed in the outer cover 11 under the heating action of the blast assembly, so as to meet the heating requirements when the cloth is tentered, and the transmission assembly in the drafting mechanism cooperates with the accessory chain 2 and the cloth pulling device to perform fixed pulling in the width direction of the cloth, so that the cloth can be subjected to transverse drafting in a high temperature environment, and the weft direction can be widened and uniform, so as to meet the subsequent production and processing requirements; The accessory chain 2 cooperates with the transmission component to carry a number of cloth pullers to move cyclically in the outer cover 11, wherein the moving speed matches the moving speed of the cloth when the direction is unidirectional movement. The lower clamping plate 3 and the upper clamping plate 31 in the cloth puller will clamp the left and right sides of the cloth entering the outer cover 11 under the action of the flipper to meet the processing needs. This method can effectively improve the processing efficiency and improve production continuity.

[0022] The transmission assembly includes a motor 4, a transmission shaft 41 and a transmission wheel 42. There are two transmission shafts 41 and transmission wheels 42 are provided at both ends. The two transmission shafts 41 are distributed left and right in the outer cover 11. The motor 4 is arranged on the outside of the outer cover 11 and one of the transmission shafts 41 is connected to the output shaft of the motor 4. The accessory chain 2 is arranged between the two transmission wheels 42 on the same side.

[0023] The motor 4 cooperates with the transmission shaft 41 and the transmission wheel 42 to provide continuous rotational force for the cyclic movement of the accessory chain 2 .

[0024] The flipper includes a gear 43, a rack 44 and an elastic member. The gear 43 is coaxially connected to the rotating shaft of the upper clamp plate 31 and is located on the side of the connecting ear. The rack 44 is slidably connected to the connecting ear back and forth and meshes with the gear 43. The elastic member is arranged between the rack 44 and the connecting ear.

[0025] A back plate 45 matching the accessory chain 2 is disposed in the outer cover 11 . The rack 44 is kept in sliding contact with the back plate 45 under the action of the elastic member. An isosceles trapezoidal guide groove 46 matching the rack 44 is formed on the upper side of the back plate 45 .

[0026] When the cloth pulling device is moving and not corresponding to the isosceles trapezoidal guide groove 46 area of ​​the back plate 45, the rack 44 is abutted by the back plate 45 and slides to the side away from the back plate 45, wherein the meshing direction of the rack 44 and the gear 43 is that the rack 44 is at the bottom, and this state will cause the upper clamping plate 31 to flip upward and maintain the open state with the lower clamping plate 3, that is, to meet the edge alignment and matching requirements when the cloth enters the outer cover 11; When the cloth pulling device corresponds to the isosceles trapezoidal guide groove 46 area, the rack 44 will slide toward the side close to the back plate 45 under the action of the elastic member, that is, the rack 44 drives the gear 43 to rotate, and at this time, the upper clamping plate 31 turns toward the side of the lower clamping plate 3, thereby clamping and fixing the cloth, so as to achieve a lateral traction state when the cloth is subsequently heated; The elastic member can be any component with elastic force such as a spring, etc., and can be set in various ways such as being sleeved on the rack 44 or between the lower end of the rack 44 and the back plate 45. No restrictions are made on multiple directions and forms.

[0027] The blowing assembly includes a blower 5, a heater 51 and an air return duct 52. The base 1 is provided with an air collection groove 53 located in the outer cover 11 and corresponding to the transmission assembly. The air collection groove 53 has a right-angled triangle structure in a vertical side view and the right-angled side is located at the upper end. The heater 51 is arranged in the air collection groove 53, the blower 5 is arranged in the outer cover 11, and the air return duct 52 connects the blower 5 and the air collection groove 53.

[0028] When the blower 5 is started, it generates output wind and the output direction is toward the wind collecting slot 53. The structure of the wind collecting slot 53 can reduce wind resistance when the wind blows, and improve the efficiency and effect of wind gathering. When the wind enters the wind collecting slot 53, it will pass through the heater 51 to be heated, and finally enter the blower 5 again through the return air duct 52 and be output, thereby forming a circulation in the space, so as to quickly increase the temperature in the outer cover 11 and heat the cloth.

[0029] A filter screen is also provided at the opening of the air collecting slot 53 .

[0030] In this way, impurities dropped from the cloth can be filtered and blocked, thereby reducing the maintenance frequency of the blower 5 and the heater 51.

[0031] Example 2: Figure 2 , 6 As shown, it is a further improvement based on Example 1. Taking into account that different cloth widths are not the same, in order to meet the processing needs of cloths of different sizes, the transmission shaft 41 is provided with an opening facing a step cavity away from the motor 4, and a limit plate 61 is provided in the step cavity for sliding sealing. The limit plate 61 is concentrically connected with a telescopic shaft 6 extending out of the step cavity. The telescopic shaft 6 is slidably connected to the opening of the step cavity by a guide rib, and the other end of the telescopic shaft 6 is rotatably connected to the back plate 45 on the other side. An adjusting cover 62 is fixed to the outer cover 11 and is rotatably connected to another transmission shaft 41 without the motor 4. The adjusting cover 62 is hollow and is connected to an external pump suction device fluid circuit. The step cavity of this transmission shaft 41 passes through the transmission shaft 41 and is connected to the adjusting cover 62. The step cavity space between the adjusting cover 62 and the limit plate 61 is completely filled with hydraulic oil.

[0032] When facing fabrics of different widths, the hydraulic oil can be pumped out through an external pump such as a liquid, so that the amount of hydraulic oil in the step cavity of the transmission shaft 41 changes. When the amount of oil increases, the limit plate 61 and the telescopic shaft 6 are pushed out, that is, the interval between the two back plates 45 is expanded. When the amount of oil decreases, the limit plate 61 and the telescopic shaft 6 are pulled back by negative pressure, that is, the interval between the two back plates 45 is reduced. In this way, the control of the hydraulic oil can achieve the state of pushing the interval distance between the two back plates 45 to meet the processing needs of fabrics of different widths. At the same time, during the adjustment, it will not affect the operation of other components such as the transmission assembly and the accessory chain 2, thereby ensuring the stability of the device.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
