Description

Technical Field

[0001] The present invention relates to the technical field of flat hoses, and particularly to a hose auxiliary threading and preheating device. Background Art

[0002] Currently, in the production process of traditional flat hoses, a hose is threaded into a strip blank made of fiber material, and then through the injection of steam, the hose and the strip blank are vulcanized and fused together after a certain process time to form a finished flat tube. However, in the process of threading the hose into the strip blank, problems such as large quality and production energy consumption losses often occur. For example, when the hose and the strip blank are vulcanized and fused in winter, due to the cold and hard hose, the long length of the vulcanized tube, the uneven heat reception of the vulcanized steam entering the hose or the long heat reception time of some parts of the heated part, exceeding the process requirements, local damage of the hose will occur, resulting in liquid leakage when the flat hose is used; for example, when the hose needs to be threaded into the strip blank made of fiber material, due to the increase in friction, the load of the threading traction motor increases and the energy consumption increases; for example, in the process of threading the hose into the strip blank, the static electricity generated by the friction between the hose and the fiber material strip blank is likely to cause damage to the on-site electronic control components and discomfort in the working environment of production personnel.

[0003] In summary, the following problems need to be solved urgently in the production process of flat hoses at present: ① There are problems of large threading resistance and high energy consumption when the hose is threaded into the strip blank made of fiber material; ② In winter, due to the high hardness of the hose, there are problems of uneven vulcanization effect and low peel strength after the hose is threaded into the strip blank; ③ In the process of threading the hose and the strip blank, the problem of static electricity causing damage to the electronic control components. Summary of the Invention

[0004] The purpose of the present invention is to design a hose auxiliary threading and preheating device for the above problems caused by the threading of the hose into the strip blank in the current production process of flat hoses, which solves the above problems.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0006] The present invention designs a hose auxiliary threading and preheating device, which is arranged below the vulcanizing table. The vulcanizing table is grounded and is provided with a traction wheel for pulling the hose. The preheating device includes the following structural settings:

[0007] A hose storage frame for storing hoses, and a first guide wheel is arranged on the hose storage frame;

[0008] A heating tank, in which a heater, a liquid level sensor, a temperature sensor and several second guide wheels are provided. The traction wheel pulls the rubber hose stored in the rubber hose storage frame through the first guide wheel and the second guide wheels in sequence and into the heating tank, and the mixed liquid preheats it. The preheated rubber hose is pulled into the vulcanizing table;

[0009] A water supply unit, which is used to supply water to the heating tank;

[0010] A lubricant supply unit, which is used to provide lubricant to the heating tank. The lubricant is mixed with water to form the mixed liquid;

[0011] And a control box, which is used to control the operation / stop of the water supply unit and the lubricant supply unit.

[0012] Specifically, the heater is used to heat the mixed liquid, and the traction wheel is driven by a traction motor.

[0013] Further, a rubber hose auxiliary threading and preheating device: The preheating device further includes a deflector for collecting the mixed liquid, which is arranged on the heating tank and one end extends to the vulcanizing table; The rubber hose preheated by the mixed liquid enters the vulcanizing table through the deflector.

[0014] Further, a rubber hose auxiliary threading and preheating device: The second guide wheels are arranged in four, two of which are respectively arranged on the top of the heating tank, and the remaining two are arranged on the bottom of the heating tank.

[0015] Further, a rubber hose auxiliary threading and preheating device: The water supply unit includes the following:

[0016] A water storage tank, which is communicated with the heating tank;

[0017] A water pump, which is arranged on the passage between the water storage tank and the heating tank and is used to supply water to the heating tank;

[0018] And a first proportional valve, which is arranged on the passage between the water storage tank and the heating tank and is used to control the water supply volume in the heating tank;

[0019] Wherein, the water pump and the first proportional valve are controlled by the control box to operate / stop.

[0020] Further, a rubber hose auxiliary threading and preheating device: The lubricant supply unit includes the following:

[0021] A lubricant storage tank, which is communicated with the heating tank;

[0022] A lubricant pump, which is arranged on the passage between the lubricant storage tank and the heating tank and is used to provide lubricant to the heating tank;

[0023] and a second proportional valve, which is arranged on the passage between the lubricant storage tank and the heating tank, and is used to control the supply amount of the lubricant in the heating tank;

[0024] Wherein, the lubricant pump and the second proportional valve are controlled to run / stop by the control box.

[0025] Advantages of the present invention:

[0026] (1) The hose-assisted threading preheating device designed by the present invention preheats the hose by using a mixed liquid composed of water and lubricant. At this time, due to the action of the lubricant, the threading resistance of the hose penetrating into the strip blank will be greatly reduced, and it is easier to penetrate. Then the load of the driving motor for driving the hose to penetrate into the strip blank becomes smaller, and the energy consumption can be reduced. Therefore, using the preheating device of the present invention can solve the problems of large threading resistance and high energy consumption when the hose penetrates into the flat strip blank.

[0027] (2) Since the hose is heated and softened by the mixed liquid, the flat hose formed by threading the hose and the strip blank is vulcanized by steam. When the steam is input, it can quickly reach the end of the production length of the flat hose. At this time, the hose is vulcanized with uniform heat, and the vulcanization time of each part is the same, and the vulcanization effect is consistent. Therefore, after using the preheating device designed by the present invention, the problems of uneven vulcanization effect and low peel strength caused by the high hardness of the hose in winter when penetrating into the flat strip blank can be solved.

[0028] (3) Since the hose is preheated by the mixed liquid in the heating tank and then pulled to the vulcanization table, the surface of the hose is attached with the mixed liquid. When the hose penetrates into the strip blank, the friction force is reduced, and the amount of static electricity generated is small. The small amount of static electricity generated can quickly be introduced into the ground through the grounding setting of the vulcanization table due to a certain humidity. Therefore, using the preheating device designed by the present invention can solve the problem of damaging the electronic components of on-site automation equipment due to the generation of static electricity caused by the friction between the hose and the strip blank during the tube threading process.

[0029] (4) In the hose-assisted threading preheating device designed by the present invention, a deflector plate is also provided. After the hose is preheated by the mixed liquid, it is pulled into the vulcanization table through the deflector plate. At this time, the mixed liquid attached to the hose will drip. Through the setting of the deflector plate, part of the dripped mixed liquid can be deflected back into the heating tank, avoiding the waste of the mixed liquid and saving costs.

[0035] Embodiment 1

[0036] As Figure 1 shown, Embodiment 1 of the present invention designs a hose auxiliary threading and preheating device. The preheating device is arranged below the vulcanizing table 1. The vulcanizing table 1 is grounded and is provided with a traction wheel 11 for pulling the hose 6. The preheating device includes the following structural settings:

[0037] The rubber hose storage frame 2 is used to store the rubber hoses 6, and a first guide wheel 21 is also provided on the rubber hose storage frame 2;

[0038] The heating tank 3 is provided with a liquid heater 31, a liquid level sensor 32, a temperature sensor 33 and four second guide wheels 34. Two of the second guide wheels 34 are respectively arranged at the top of the heating tank 3, and the remaining two second guide wheels 34 are arranged at the bottom of the heating tank 3. The traction wheel 11 traction the rubber hoses 6 stored in the rubber hose storage frame 2 to enter the heating tank 3 through the first guide wheel 21 and the second guide wheels 31 in sequence, and the mixed liquid 35 preheats the rubber hoses. A flow guide plate 8 is also provided on the heating tank 3, and one end of the flow guide plate 8 extends to the vulcanizing table 1. The rubber hoses 6 preheated by the mixed liquid 35 are traction into the vulcanizing table 1 through the flow guide plate 8;

[0039] The water supply unit 4 includes a water storage tank 41, a water pump 42 and a first proportional valve 43. The water storage tank 41 is communicated with the heating tank 3. The water pump 42 is arranged on the path between the water storage tank 41 and the heating tank 3 to supply the stored water in the water storage tank 41 into the heating tank 3. The first proportional valve 43 is arranged on the path between the water storage tank 41 and the heating tank 3, and it is used to control the water supply amount into the heating tank 3;

[0040] The lubricant supply unit 5 includes a lubricant storage tank 51, a lubricant pump 52 and a second proportional valve 53. The lubricant storage tank 51 is communicated with the heating tank 3. The lubricant pump 52 is arranged on the path between the lubricant storage tank 51 and the heating tank 3 to supply lubricant into the heating tank 3. The second proportional valve 53 is arranged on the path between the lubricant storage tank 51 and the heating tank 3, and it is used to control the lubricant supply amount into the heating tank 3. The lubricant and water are mixed to form the mixed liquid 35;

[0041] And the control box 7 is used to control the operation / stop of the water pump 42 and the lubricant pump 52, and control the opening degrees of the first proportional valve 43 and the second proportional valve 53.

[0042] The rubber hose auxiliary tape threading preheating device designed in the above-mentioned Embodiment 1 can first preheat and soften the rubber hose 8, and then the rubber hose 8 is conveyed to the vulcanizing table 1 through the first guide wheel 21, the second guide wheel 34 and the flow guide plate 8, and then the tube threading vulcanization operation of the fiber tape blank and the rubber hose 8 is carried out. Its specific working process is as follows: The rubber hose 6 in the rubber hose storage frame 2 is pulled by the traction wheel 11 on the vulcanizing table 1 through the first guide wheel 21 and the second guide wheel 34 into the heating tank 3, and the mixed liquid 35 preheats it; the water pump 42, the lubricant pump 52, the first proportional valve 43 and the second proportional valve 53 are adjusted to operate through the control box 7, so that the water storage tank 41 and the lubricant storage tank 51 inject liquids into the heating tank respectively according to the set ratio to form the mixed liquid 35. The heating tank 3 is provided with a heater 31, a liquid level sensor 32 and a temperature sensor 33 for heating the mixed liquid 35 to ensure the best production elements required by the production process. After being heated by the mixed liquid 35, the rubber hose 8 is pulled by the traction wheel 11 and enters the vulcanizing table 1 through the flow guide plate 8. At this time, the rubber hose 8 is hot and the mixed liquid 35 adheres to the rubber hose. The excess mixed liquid 35 flows back into the heating tank 3 through the flow guide plate 8. Subsequently, the rubber hose 8 can be hooked and fixed by the tape threading wheel (not shown in the figure) in the vulcanizing table 1, and the tape blank is inserted into the rubber hose 8 through the other end of the tape threading wheel. At this time, due to the action of the mixed liquid 35 (lubricant), the threading resistance between the tape blank and the rubber hose is small and it is easy to penetrate. Therefore, the load of the tape threading traction motor (i.e., the motor driving the rubber hose to penetrate into the tape blank) becomes smaller and the energy consumption is reduced, solving the problems of large threading resistance and high energy consumption when the rubber hose penetrates into the flat tape blank; at the same time, after the rubber hose 8 is preheated and softened by the mixed liquid 35, it solves the problems of uneven vulcanization effect and low peeling strength caused by the high hardness of the rubber hose 8 in winter after the rubber hose penetrates into the flat tape blank; furthermore, after the rubber hose 8 is preheated by the mixed liquid 35, the mixed liquid 35 will adhere to its surface, which can reduce the friction force during the tape blank threading process, generate less static electricity, and the small amount of static electricity generated can also be quickly introduced into the ground through the grounding setting on the vulcanizing table 1 due to a certain humidity, solving the problem of damaging the electronic components of the on-site automation equipment due to static electricity generation during the tube threading process of the rubber hose 8 and the tape blank.

[0043] In the production process of traditional flat hoses, the rubber hose 8 needs to be inserted into the strip blank woven from fiber materials. Through the injection of steam and after a certain technological time, the rubber hose 8 and the strip blank are vulcanized and fused together to form a finished flat hose. In this process, there will be problems such as large threading resistance between the rubber hose 8 and the strip blank, poor fusion degree between the rubber hose 8 and the strip blank, uneven thickness of the fusion between the rubber hose and the strip blank, low peel strength, local damage to the rubber hose, and a large amount of static electricity generated. In view of the above disadvantages, the rubber hose auxiliary threading and preheating device designed in Embodiment 1 can solve the following problems: ① the problem of large threading resistance and high energy consumption when the rubber hose 8 is inserted into the strip blank; ② the problem of uneven vulcanization effect and low peel strength after the rubber hose 8 is inserted into the strip blank due to the high hardness of the rubber hose in winter; ③ the problem of damage to on-site electronic control components caused by frictional static electricity during the process of threading the rubber hose 8 and the strip blank.

[0044] The above are the preferred embodiments of the present invention, which are only used to explain the present invention and are not used to limit the present invention. Any obvious changes or variations derived from the technical solutions of the present invention are still within the protection scope of the present invention.
