Description

Technical Field

[0001] The utility model relates to the technical field of fabric finishing, in particular to a fabric finishing and shaping device. Background Art

[0002] Fabric heat setting is a fabric post-processing process that mainly uses heat to eliminate the internal stress generated by the fabric fibers during the stretching process, causing the macromolecules to relax to a certain extent, thereby fixing the shape of the woven fibers. Pressure is then applied to keep the fabric surface flat to obtain a fabric with high surface smoothness and high strength.

[0003] At present, hot air is generally used to heat the fabric, and then two pressure rollers are used to flatten the fabric to increase the fabric quality. Hot air heating generally uses a longer heating box. By increasing the temperature of each chamber of the heating box, the fabric is gradually heated from room temperature to the process temperature. However, in order to ensure the temperature of each position of the fabric, flowing hot air is used for heating to prevent uneven heating of each position of the fabric. However, a large amount of hot air is required to ensure the temperature of the fabric in a large cavity, and the outflowing hot air will increase energy loss.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a fabric finishing and shaping device.

[0006] The above-mentioned technical purpose of the present invention is achieved through the following technical solutions: a fabric finishing and shaping device comprises a shell with a cavity therein, two support plates are fixedly connected to the upper end of the shell, and an unfolding roller in contact with the cloth is rotatably connected between the inner wall of the cavity and the two support plates, the cloth passes through the cavity from the side position of the shell and extends upward around the roller surface of the unfolding roller therein, and the cloth passes upward to the upper position of the shell and then around the roller surface of the unfolding roller at the upper position, the cloth divides the cavity into an upper cavity and a lower cavity and makes the unfolding roller in the cavity located in the upper cavity, the wall of the lower cavity away from the position where the cloth enters the cavity is penetrated by an air outlet duct, and the air outlet duct extends to directly below the unfolding roller and divides the lower cavity into a negative pressure cavity directly below the upper cavity and a accommodating cavity located on the side of the upper cavity, and the side wall of the accommodating cavity away from the upper cavity is penetrated by a hot air outlet.

[0007] By adopting the above technical solution, hot air is blown toward the cloth through the hot air outlet, so that the hot air passes through the cloth above the unfolding roller and enters the upper cavity, heating the cloth passing through the shell, and then the air outlet pipe is used to provide negative pressure to the negative pressure cavity, and the hot air that continuously enters the upper cavity increases the pressure of the upper cavity, thereby forming positive pressure and negative pressure on both sides of the cloth that has just entered the cavity, prompting the hot air in the upper cavity to pass through the cloth that has just entered the cavity, completing the preheating of the cloth, that is, the cloth is first heated by hot air at a lower temperature before contacting the unfolding roller to complete the preheating, and then contacts the hot air that has just flowed out of the hot air outlet to complete the heating, so that the hot air heats the cloth twice in succession, which not only gradually heats up the cloth, but also reduces heat loss.

[0008] The present invention is further configured as follows: a position of the shell for the cloth to pass through upward is penetrated by a slot in a direction away from the position where the cloth enters the cavity, and the slot passes upward, and a pressing block and a fixing assembly are provided on the slot, and the pressing block moves in a direction perpendicular to the surface of the position where the cloth passes through upward, and then the position of the pressing block is fixed by the fixing assembly and the spacing of the space when the cloth passes through the shell upward is controlled.

[0009] By adopting the above technical solution, the distance between the pressing block and the shell can be adjusted according to the thickness of the cloth by moving the pressing block on the slot, so that the pressing block presses the cloth. After the cloth is heated, the pressing block applies pressure to the surface of the cloth, thereby increasing the flatness of the cloth surface, thereby increasing the scope of use of the utility model and improving product quality.

[0010] The utility model is further configured as follows: the fixing assembly includes a plurality of threaded columns fixed on the bottom wall of the slot and facing upward, the upper end of the pressure block is penetrated by a plurality of sliding grooves extending along the moving direction of the pressure block, the threaded column passes through the sliding grooves and extends to the top of the pressure block, and the threaded column is threadedly connected to a nut that abuts the upper end of the pressure block.

[0011] By adopting the above technical solution, after adjusting the position of the pressing block, the nut is rotated to reduce the distance between the nut and the bottom wall of the slot, and the nut is brought into contact with the upper end of the pressing block, thereby fixing the pressing block on the slot.

[0012] The utility model is further configured as follows: the top and side walls of the upper cavity on the cloth moving track surface are connected arc surfaces.

[0013] By adopting the above technical solution, after the hot air passes through the cloth and enters the upper cavity, the gas turns from the horizontal direction along the inner wall of the upper cavity to toward the cloth, thereby increasing the efficiency of the hot air passing through the newly entered cloth, thereby increasing the preheating effect of the cloth.

[0014] The utility model is further configured as follows: the hot air outlet is directed toward the cloth surface where the cloth is unfolded around the roller in the cavity and extends upward.

[0015] By adopting the above technical solution, the hot air outlet is directed to the cloth passing through the position of the unfolding roller in the cavity, thereby further increasing the efficiency of the hot air passing through the cloth and enhancing the heating effect of the cloth.

[0016] The utility model is further configured as follows: there is a gap between the cloth and the front and rear walls of the cavity.

[0017] By adopting the above technical solution, the gap between the cloth and the front and rear walls of the cavity is utilized. When the air permeability of the cloth is low, the hot air flowing out of the hot air outlet flows into the upper cavity through the gap. The hot air then passes through the gap at the lower cloth position along the arc of the side wall of the upper cavity and enters the negative pressure cavity. The hot air then flows out through the air outlet pipe, that is, airflow is formed on both sides of the cloth at the upper cavity position. The airflow in the upper cavity is caused to flow out by utilizing the principle of low pressure at a position with fast flow rate, thereby reducing the pressure in the upper cavity, further increasing the efficiency of the hot air in the accommodating cavity passing through the cloth and entering the upper cavity, thereby increasing the heating effect. At the same time, when the hot air flows through the gap, it also contacts the unfolding roller and transfers heat to the unfolding roller. The unfolding roller then contacts the cloth and transfers heat to the other side of the cloth, thereby further increasing the heating effect of the cloth.

[0018] The utility model is further configured such that: there is a gap between the air outlet pipe and the cloth at the position of the unfolding roller.

[0019] By adopting the above technical solution, when the fabric has a strong wind-blocking effect, after the hot air blows towards the fabric, the hot air in the accommodating chamber enters the negative pressure chamber from the gap between the air outlet pipe and the fabric, and forms an airflow on the surface of the fabric at the lower position, thereby heating a single side of the fabric, and the direction of the airflow is opposite to the direction of movement of the fabric, thereby gradually increasing the temperature of the fabric, preventing the fabric temperature from rising instantly and affecting its performance.

[0020] The utility model is further configured as follows: the side wall of the negative pressure chamber away from the air outlet pipe is a semicircular concave arc surface.

[0021] By adopting the above technical solution, after the hot air in the accommodating cavity passes through the gap between the air outlet pipe and the cloth and enters the negative pressure cavity, the hot air impacts the concave arc surface of the negative pressure cavity and follows its arc surface, causing the airflow direction to turn 360 degrees and flow out from the air outlet pipe, preventing the hot air from impacting the inner wall of the negative pressure cavity and escaping to the surroundings and affecting the airflow at the surface of the cloth, thereby further increasing the preheating effect of the cloth.

[0022] In summary, the present invention has the following beneficial effects:

[0023] Hot air is blown toward the fabric through the hot air outlet to heat the fabric. At the same time, the hot air passes through the fabric and enters the upper cavity. The hot air passes through the fabric again and enters the negative pressure cavity, and then flows out through the air outlet pipe, completing two passes through the fabric and heating and preheating the fabric, reducing heat loss and heat emission. At the same time, the pressure of the pressing block squeezing the fabric can be adjusted according to the different thickness of the fabric, thereby increasing the leveling effect and thus improving product quality.

[0030] The present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Example 1:

[0032] This kind of fabric finishing and shaping device, such as Figures 1 to 4As shown, it includes a shell 11 with a cavity therein, two support plates 20 are fixedly connected to the upper end of the shell 11, and an unfolding roller 16 in contact with the cloth 13 is rotatably connected between the inner wall of the cavity and the two support plates 20. The cloth 13 penetrates into the cavity from the side position of the shell 11 and extends upward around the roller surface of the unfolding roller 16 therein, and the cloth 13 penetrates upward to the upper position of the shell 11 and then around the roller surface of the unfolding roller 16 at the upper position. The cloth 13 divides the cavity into an upper cavity 15 and a lower cavity and makes the unfolding roller 16 in the cavity located in the upper cavity 15. The wall of the lower cavity away from the position where the cloth 13 enters the cavity is penetrated by an air outlet duct 19, and the air outlet duct 19 extends to just below the unfolding roller 16 and divides the lower cavity into a negative pressure cavity 14 just below the upper cavity 15 and a accommodating cavity 23 located on the side of the upper cavity 15. The side wall of the accommodating cavity 23 away from the upper cavity 15 is penetrated by a hot air outlet 18. The position of the shell 11 for the cloth 13 to penetrate upward A slot 12 is penetrated in the direction away from the position where the cloth 13 enters the cavity, and the slot 12 penetrates upward. A pressure block 21 and a fixing assembly are provided on the slot 12. The pressure block 21 moves in a direction perpendicular to the surface of the position where the cloth 13 penetrates upward, and the position of the pressure block 21 is fixed by the fixing assembly and the spacing of the space for the cloth 13 to penetrate upward through the shell 11 is controlled. The fixing assembly includes a plurality of threaded columns 17 fixed to the bottom wall of the slot 12 and facing upward. The upper end of the pressure block 21 is penetrated by a plurality of sliding grooves 22 extending along the moving direction of the pressure block 21. The threaded column 17 passes through the sliding groove 22 and extends to the top of the pressure block 21. A nut is threadedly connected to the threaded column 17 and abuts against the upper end of the pressure block 21. The top and side walls of the upper cavity 15 on the moving track surface of the cloth 13 are connected arc surfaces. The hot air outlet 18 faces the surface of the cloth 13 where the cloth 13 is unfolded around the roller 16 in the cavity and extends upward. There is a gap between the cloth 13 and the front and rear walls of the cavity.

[0033] The hot air outlet 18 is used to blow hot air into the accommodating chamber 23, and the air outlet 19 absorbs the hot air in the accommodating chamber 23, and the amount of gas discharged by the air outlet 19 is greater than twice the amount of hot air introduced by the hot air outlet 18, so that the accommodating chamber 23 is under negative pressure relative to the external environment. At the same time, the position where the cloth 13 enters the inlet of the accommodating chamber 23 is subject to the negative pressure in the accommodating chamber 23, so that the gas of the external environment enters the accommodating chamber 23 from the position far away from the hot air outlet 18, thereby reducing the temperature of the position, so that the temperature of each position in the accommodating chamber 23 gradually decreases from the hot air outlet 18 to the position where the cloth 13 enters the inlet of the accommodating chamber 23. When the hot air enters the accommodating chamber 23 from the hot air outlet 18, the hot air directly hits the surface of the cloth 13. When the cloth 13 has good air permeability, the hot air passes through the cloth 13 and enters The hot air in the upper chamber 15 is passed through the cloth 13 and preheated for the first time. The hot air then flows out through the air outlet 19, and the cloth 13 is preheated twice and once by a hot air stream, so that the cloth 13 is gradually heated up to prevent the cloth 13 from being heated. 3 directly contacts with the hot air of excessive temperature, causing the fabric 13 to heat up extremely quickly, thereby preventing the performance of the fabric 13 from being degraded. The hot air outlet 18 is connected to the external hot air system and provides hot air, while the air outlet 19 is connected to the negative pressure pipe of the external environment and provides negative pressure to the negative pressure chamber 14, absorbing the residual hot air in the negative pressure chamber 14. Then, by using the two opposite threads on the unrolling roller 16, when the fabric 13 contacts and moves with the roller surface of the unrolling roller 16, the threads on the unrolling roller 16 unroll the fabric 13 to both ends of the unrolling roller 16, preventing the fabric 13 from wrinkling when it moves on the roller surface, and also preventing wrinkles at some positions from causing uneven heating of the fabric 13, further enhancing the effect of heat finishing, and then by using the setting of the pressing block 21 at the slot 12, adjusting the position of the pressing block 21 and controlling the pressure The spacing between the block 21 and the shell 11, that is, the width of the position where the cloth 13 passes through the cavity, is controlled to adapt to cloths 13 of different thicknesses, thereby increasing the scope of application of the present invention. The top wall of the slot 12 is fixedly connected with a threaded column 17 passing through the sliding groove 22, and the threaded column 17 is threadedly connected with a nut located above the pressing block 21, so that the pressing block 21 slides along the direction of the sliding groove 22, and then the nut is rotated and locked, thereby fixing the pressing block 21 and the shell 11, completing the position control of the pressing block 21, wherein the hot air port 18 and the air outlet pipe 19 are oriented in the same direction so that the hot air first passes into the upper cavity 15 and then is guided by the inner wall of the upper cavity 15 and is pulled by the air outlet pipe 19 and flows out, which not only increases the heating effect of the hot air on the cloth 13, but also increases the effect of the hot air flowing in the cavity;

[0034] The fixing assembly is then used to control the horizontal distance between the pressing block 21 and the housing 11, thereby controlling the pressure of the pressing block 21 on the surface of the cloth 13 and controlling the width of the cloth 13, thereby increasing the shaping effect.

[0035] Example 2:

[0036] The difference of this fabric finishing and shaping device is that there is a gap between the air outlet pipe 19 and the fabric 13 at the position of the unfolding roller 16, and the side wall of the negative pressure chamber 14 away from the air outlet pipe 19 is a semicircular concave arc surface.

[0037] When the cloth 13 has a strong windproof effect, hot air flows into the negative pressure chamber 14 from the gap between the air outlet pipe 19 and the cloth 13 at the position of the unfolding roller 16, so that the hot air contacts one side of the cloth 13. At the same time, the airflow direction is opposite to the moving direction of the cloth 13, thereby gradually heating up the cloth 13 and entering the negative pressure chamber 14 and abutting against the left wall of the negative pressure chamber 14. The hot air flow is guided by the left wall of the negative pressure chamber 14, and the airflow direction is reversed and flows out from the air outlet pipe 19, thereby heating and preheating the cloth 13 with a strong windproof effect.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
