Description

Technical Field

[0001] The utility model belongs to the technical field related to a shaping machine, and in particular relates to an exhaust structure of a shaping machine. Background Art

[0002] The shaping machine uses natural gas combustion (or hot oil and other heating methods) to heat the air in the box. The cloth passes through the equipment to achieve the purpose of drying and shaping the cloth. After entering the dryer, the cloth is mainly divided into two processes. The first process is the process of rapid evaporation of water vapor at high temperature. The content of water vapor in the exhaust gas of this process is relatively high, the exhaust gas generated by the additive is relatively high, and the exhaust gas content generated by natural gas combustion is relatively high; the second process is the drying process of the cloth. The oil content in the exhaust gas in this process is relatively high, and the exhaust gas content is relatively high. In order to ensure the versatility of the cloth, the shaping machine adopts an open design during the design process, that is, the amount of exhaust gas generated during operation is less than the exhaust volume of the main equipment fan, and the oven is always in a negative pressure working state, that is, no matter how much exhaust gas is generated, whether the exhaust gas content is really saturated or not, it will be discharged, which causes a lot of heat waste and greatly increases the gas cost.

[0003] The amount of exhaust gas generated by the shaping machine for different types of cloth during use is different. Generally speaking, heavier cloth has a higher water content than lighter cloth, so it is slower to shape and spends longer time in the oven, generating more water vapor, combustion exhaust gas, and oil-containing exhaust gas. Compared with chemical fiber cloth, cotton cloth will generate more water vapor, combustion exhaust gas, and oil-containing exhaust gas due to the different materials. Compared with woven cloth, knitted cloth will generate different water vapor, combustion exhaust gas, and oil-containing exhaust gas due to the different weaving processes. Obviously, if the shaping machine wants to save energy, it can think of ways to improve its open exhaust design.

[0004] At present, the simple and crude method used by various factories is to install an exhaust valve on the exhaust duct and adjust the air volume by adjusting the angle of the valve core. This adjustment method is completely artificial and indeterminate.

[0005] The utility model is aimed at improving the above-mentioned problem and specifically relates to an exhaust structure of a setting machine. Utility Model Content

[0006] The purpose of the utility model is to provide an exhaust structure for a setting machine to solve the problem that the setting machine proposed in the above background technology adopts an open design in the design process to ensure the versatility of cloth, that is, the amount of exhaust gas generated during operation is less than the exhaust volume of the main equipment fan, and the oven is always in a negative pressure working state, that is, no matter how much exhaust gas is generated, it will be discharged whether the exhaust gas content is really saturated, which causes a lot of heat waste and greatly increases the gas cost.

[0007] To achieve the above object, the utility model provides the following technical solutions: an exhaust structure of a setting machine, comprising a setting machine housing and a setting machine front housing baffle arranged at the side of the setting machine housing; a needle plate chain body is connected to the end of the setting machine housing near the bottom;

[0008] A Teflon cloth detection curtain is arranged at the side position of the baffle plate of the front box body of the setting machine, a Teflon counterweight is arranged at the bottom position of the Teflon cloth detection curtain, and an ultrasonic detection body is arranged at the outer side position of the Teflon cloth detection curtain. When the setting machine is working normally, the amount of waste gas generated is greater than the exhaust air volume, which will form a positive pressure in the oven. At this time, the hot air in the oven will be discharged from the cloth inlet and air outlet of the setting machine. The hot air discharged from the oven has a certain pressure, and when it reaches a certain level, the detection curtain will be blown up; if the amount of waste gas generated is less than the exhaust air volume, a negative pressure will be formed in the oven. At this time, cold air in the oven will enter from the cloth inlet and air outlet of the setting machine, which will reduce the temperature in the oven. Negative pressure will be generated when the oven sucks air, and when it reaches a certain level, the detection curtain will be sucked into the inside of the oven.

[0009] Preferably, the Teflon counterweight is made of metal iron material, and the Teflon counterweight is bonded and installed to the Teflon cloth detection curtain by adhesive.

[0015] Compared with the prior art, the utility model provides an exhaust structure of a setting machine, which has the following beneficial effects:

[0016] In the exhaust structure of the setting machine, a Teflon cloth detection curtain is arranged at the side position of the baffle plate of the front box of the setting machine, a Teflon cloth detection curtain is arranged at the bottom position of the Teflon cloth detection curtain, and an ultrasonic detection body is arranged at the outer side position of the Teflon cloth detection curtain. When the setting machine works normally, the amount of waste gas generated is greater than the exhaust air volume, which will form a positive pressure in the oven. At this time, the hot air in the oven will be discharged from the cloth inlet and air outlet of the setting machine. The hot air discharged from the oven has a certain pressure, and when it reaches a certain level, the detection curtain will be blown up; if the amount of waste gas generated is less than the exhaust air volume, a negative pressure will be formed in the oven. At this time, the cold air in the oven will be discharged from the cloth inlet and air outlet of the setting machine. When the air enters the outlet, the temperature inside the oven will drop. When the oven sucks air, negative pressure will be generated. When it reaches a certain level, the detection curtain will be sucked into the oven. In this way, the wind pressure inside the setting machine cabinet can be known through the change in temperature. Then, the position of the detection curtain is measured by ultrasonic wave to control the frequency converter of the setting machine fan. When the ultrasonic wave detects that the distance is decreasing, it proves that the air pressure in the oven is increasing and the positive pressure needs to be released, then the frequency converter needs to be increased; when the ultrasonic wave detects that the distance is increasing, it proves that the air pressure in the oven is decreasing and is in a negative pressure state, then the frequency converter needs to be reduced, thereby effectively reducing heat loss and resource waste, thereby improving the practicality of the setting machine.

[0017] In the exhaust structure of the shaping machine, a built-in electromagnet body is arranged at the bottom position of the shaping machine casing and at the inner side position of the shaping machine casing. The bottom of the built-in electromagnet body is connected with an operation control box, and the operation control box is connected to the built-in electromagnet body through a connecting wire. The current strength of the built-in electromagnet body is controlled by the operation control box. After controlling the current strength, the magnetic strength of the built-in electromagnet body can be controlled. The size of the counterweight force of the Teflon counterweight body can be adjusted according to actual needs, making it more suitable for actual conditions. There is no need to replace the counterweight, and it is convenient to adjust, thereby effectively improving the practicality of the shaping machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-4As shown, an exhaust structure of a setting machine comprises a setting machine case 1 and a setting machine front case baffle 2 arranged at the side position of the setting machine case 1; a needle plate chain body 7 is connected to the end of the setting machine case 1 near the bottom position; a Teflon cloth detection curtain 3 is arranged at the side position of the setting machine front case baffle 2, a Teflon cloth detection curtain 3 is arranged at the bottom position of the Teflon cloth detection curtain 3, and an ultrasonic detection body 6 is arranged at the outer side position of the Teflon cloth detection curtain 3. When the setting machine works normally, the amount of waste gas generated is greater than the exhaust air volume, which will form a positive pressure in the oven. At this time, the hot air in the oven will be discharged from the cloth inlet and outlet of the setting machine. The hot air discharged from the oven has a certain pressure, and when it reaches a certain level, it will blow up the detection curtain; if the amount of waste gas generated is less than the exhaust air volume, a negative pressure will be formed in the oven. At this time, The cold air in the oven will enter from the cloth inlet and air outlet of the setting machine, which will lower the temperature in the oven. Negative pressure will be generated when the oven sucks air. When it reaches a certain level, the detection curtain will be sucked into the oven. In this way, the wind pressure inside the setting machine cabinet 1 can be known through the change in temperature. Then, the frequency converter of the setting machine fan is controlled by ultrasonic measurement of the position of the detection curtain. When the ultrasonic wave detects that the distance is decreasing, it proves that the air pressure in the oven is increasing and the positive pressure needs to be released, then the frequency conversion needs to be increased; when the ultrasonic wave detects that the distance is increasing, it proves that the air pressure in the oven is decreasing and is in a negative pressure state, then the frequency conversion needs to be reduced. The main components of the gas in the oven of the setting machine under normal working conditions are water vapor and oil vapor. When a large amount of cold air is sucked in, the water vapor and oil vapor will be condensed. The condensed water vapor and oil vapor will be vaporized again after being fully heated. If water vapor and oil gas condense and drip onto the cloth, it will cause stains on the single or multiple layers of the cloth, resulting in defective products. At present, most of the setting machines used in factories use natural gas as the main energy source, and achieve the purpose of heating through direct or indirect combustion. Natural gas combustion heating has a fast heating speed and is pollution-free, but the cost of natural gas is higher than other heating methods. In order to save energy while ensuring the quality of setting, the method of controlling the wind pressure of the oven is adopted to control the air intake and exhaust volume. It is found in actual use that properly maintaining the positive wind pressure state of the oven has a direct effect on saving natural gas, thereby effectively reducing heat loss and resource waste, thereby improving the practicality of the setting machine.

The size of the counterweight of the Teflon counterweight 4 can be adjusted according to actual needs, so that it is more suitable for the actual situation, and there is no need to replace the counterweight, which is convenient for adjustment, thereby effectively improving the practicality of the molding machine.

[0026] like Figure 3 As shown, a built-in connection resistor 12 is arranged at the internal position of the operation control box 9, and the built-in connection resistor 12 is installed and connected to the operation control box 9 by screws. A contact connection guide column 10 is arranged at the side position of the built-in connection resistor 12, and the contact connection guide column 10 is made of metal copper material. When the contact connection guide column 10 moves to the left, the resistance in the circuit decreases, the current increases, and the magnetism of the built-in electromagnet body 8 increases, and vice versa.

[0027] As Figure 3 As shown, a toggle connection block 11 is provided at the end position of the contact connection guide post 10. The toggle connection block 11 is made of polyvinyl chloride material. The toggle connection block 11 is installed and connected with the contact connection guide post 10 by a socket connection. The polyvinyl chloride material is an insulator, and being socketed on the contact connection guide post 10 can effectively prevent the user from being electric shocked.
