Description

Technical Field

[0001] The present invention relates to the technical field of hose preparation, and in particular to a quantitatively discharging ball hose and a preparation method thereof. Background Art

[0002] A hose is a flexible hollow pipe fitting. Depending on the required environment and pressure level, most hoses are made of materials such as nylon, polyurethane, polyethylene, polyvinyl chloride, polytetrafluoroethylene, synthetic rubber or natural rubber. During the actual preparation of the hose, since the hose is an one-piece molded pipe fitting in the preparation process, during the actual transportation of spherical workpieces such as balls, due to the one-piece molding characteristics of the hose and the lack of corresponding quantitative transportation function, it is difficult to grasp the actual transportation quality and quantity of the hose body, and it is impossible to achieve a more precise quantitative transportation function. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a quantitative discharging ball hose and a preparation method thereof.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A method for preparing a quantitatively discharging ball hose comprises the following steps:

[0006] Material preparation, wherein the material preparation is to prepare the raw materials for the pre-made pipe;

[0007] Refining, which is the step of subjecting the pre-prepared raw materials to a rubber refining process to convert them into prepared raw materials;

[0008] Tube embryo forming, which is the step of converting the refined raw materials into a formed embryo through a preparation device;

[0009] Vulcanization is the process of placing the tube blank into a steam vulcanization tank for forming.

[0010] Assembly, wherein the assembly is to assemble and shape the embryonic body after vulcanization to prepare it into the expected size.

[0011] The present invention is further configured as follows: in the actual material preparation process, it is necessary to prepare in advance 80-140 parts of EPDM rubber, 3-5 parts of antioxidant RD, 45-85 parts of liquid paraffin, 5 parts of repellent, and 5 parts of cross-linking agent. After preparing the above raw materials, the material body is placed in the preparation position;

[0012] Classification: According to the differences in the actual use of the prepared raw materials, classified processing is carried out. The prepared raw materials are classified one by one, the raw materials needed for step S1 are sorted, and then the raw materials in the remaining steps are sorted according to the standards in the above content, so as to achieve classified preparation.

[0013] By adopting the above technical solution: by sorting the materials in advance, the sustainable supply of raw materials is ensured in the subsequent preparation process.

[0014] The present invention is further configured as follows: the prepared raw materials are prepared and processed separately according to the provisions of the inner and outer layers, the inner layer rubber mix is ​​prepared first, and the raw materials required for the preparation of the inner layer rubber mix are put into the refining equipment. After waiting for the inner layer rubber mix to pass through the refining equipment to complete the refining, the outer layer rubber mix can be put into the refining equipment. When the outer layer rubber mix is ​​in the preparation state, the inner layer rubber mix can be filtered. Similarly, after the outer layer rubber mix is ​​prepared, it also needs to be filtered. After both of the above have completed the filtration process, the refining step can be completed.

[0015] By adopting the above technical solution: by filtering the inner and outer layer rubber mixtures one by one, it is convenient to distinguish them in the subsequent preparation process.

[0016] The present invention is further configured as follows: during the tube blank forming process, an inner layer of the rubber compound is extruded using an extrusion device. During the extrusion process, four equidistant grooves need to be reserved on the inner surface of the tube blank. The four equidistant grooves are reserved for assembling a pressure sensor during subsequent use. During the subsequent assembly process, the installation position of the pressure sensor can be confirmed based on the reserved grooves.

[0017] Use the extrusion equipment to extrude the outer layer of rubber compound, and cover the outer layer of rubber compound on the outside of the inner layer of rubber compound. After the covering is formed, the tube blank is formed. Then the tube blank preparation can be repeated according to the above operation content.

[0018] By adopting the above technical solution: by shaping the tube embryo, the subsequent preparation process can be facilitated and the steps spent on molding can be reduced.

[0019] The present invention is further configured as follows: after the tube blank is produced, the tube blank prepared in the above content is put on the outside of the mold, and after the putting is completed, the tube blank in a fixed state is placed in a steam vulcanization tank body, and then the parameters of the steam vulcanization tank are set, and the specific parameters are: steam pressure parameter is 0.75-1.1MPa, temperature is limited to 165-185℃, and vulcanization treatment time is 25-35 minutes.

[0020] The present invention is further configured as follows: the vulcanized tube blank is assembled, and the fixing assembly is used to fix the vulcanized tube blank. After the fixing is completed, the pressure sensor is fixed inside the tube blank. During the fixing process of the pressure sensor, the corresponding position between the groove and the pressure sensor needs to be confirmed, and then the fixing process is performed. After the pressure sensors are fixed one by one, the fixing process of the inner surface of the tube body can be completed.

[0021] After the assembly is completed, the tube blank is reduced in size and the cutting equipment is used to shrink the tube blank to the prefabricated size. After the cutting is completed, the next step can be completed;

[0022] The assembled tube embryo is subjected to a limiting treatment. During the limiting treatment, the front and rear ends of the tube embryo are limited by clamps. After the front and rear ends of the tube embryo are limited by the clamps, the tube embryo is stretched to test its overall tensile performance.

[0023] A quantitative ball-discharging hose, according to the above-mentioned preparation method of the quantitative ball-discharging hose, includes a hose body, the inner surface of the hose body is provided with grooves, and the hose body is equipped with pressure sensors through the grooves, there are four grooves in total, and the four grooves are arranged in a ring shape with the inner surface of the hose body as the path, there are four pressure sensors in total, and the four pressure sensors correspond to the four grooves.

[0024] The beneficial effects of the present invention are:

[0025] When the present invention is used, the materials are prepared. In the actual material preparation process, it is necessary to prepare in advance 80-140 parts of EPDM rubber, 3-5 parts of antioxidant RD, 45-85 parts of liquid paraffin, 5 parts of hydrophobizing agent, and 5 parts of cross-linking agent. After preparing the above raw materials, the material body is placed in the preparation position; classification is carried out according to the differences in the actual use methods of the prepared raw materials, and the prepared raw materials are classified one by one, the raw materials needed for use in S1 are sorted, and then the raw materials in the remaining steps are sorted according to the standards in the above content, so as to achieve classified material preparation.

[0026] The prepared raw materials are prepared and processed separately according to the regulations of inner and outer layers. The inner layer rubber mix is ​​prepared first, and the raw materials required for the preparation of the inner layer rubber mix are put into the refining equipment. After waiting for the inner layer rubber mix to pass through the refining equipment, the outer layer rubber mix can be put into the refining equipment. When the outer layer rubber mix is ​​in the preparation state, the inner layer rubber mix can be filtered. Similarly, after the outer layer rubber mix is ​​prepared, it also needs to be filtered. After both of the above are filtered, the refining step can be completed.

[0027] Tube blank forming, during the forming process, use extrusion equipment to extrude the inner layer of rubber compound. During the extrusion process, it is necessary to reserve four equidistant grooves on the inner surface of the tube blank. The four equidistant grooves are reserved for assembling the pressure sensor during subsequent use. Later in the assembly process, the installation position of the pressure sensor can be confirmed according to the reserved grooves; use extrusion equipment to extrude the outer layer of rubber compound, and cover the outer layer of rubber compound on the outside of the inner layer of rubber compound. After covering and forming, the tube blank is completed. Then the tube blank preparation can be repeated according to the above operation content.

[0028] Vulcanization: After the tube blank is made, the tube blank prepared in the above content is put on the outside of the mold. After the putting is completed, the tube blank in a fixed state is placed in the steam vulcanization tank. Then the parameters of the steam vulcanization tank are set. The specific parameters are: steam pressure parameter is 0.75-1.1MPa, temperature limit is 165-185℃, and vulcanization treatment time is 25-35 minutes.

[0029] The vulcanized tube blank is assembled and fixed with a fixing assembly. After the fixing is completed, the pressure sensor is fixed inside the tube blank. During the fixing process of the pressure sensor, the corresponding position between the groove and the pressure sensor needs to be confirmed, and then the fixing process is performed. After the pressure sensors are fixed one by one, the fixing process of the inner surface of the tube body can be completed; the assembled tube blank is reduced in size and pre-shrinked to the prefabricated size using a cutting device. After the cutting is completed, the next step can be completed; the assembled tube blank is limited. During the limiting process, the front and rear ends of the tube blank are limited by clamps. After the front and rear ends of the tube blank are limited by the clamps, the tube blank is stretched to test its overall tensile performance;

[0030] The above is the working principle involved in the preparation method. The following content will supplement the working principle generated in the actual use of the hose body: During actual use, the pressure trigger index of the pressure sensor needs to be adjusted in advance. After the adjustment is completed, the hose can be used to quantitatively transport the balls. During the process of the balls being transported on the inner wall of the hose, the balls will touch the pressure sensor. After the pressure sensor reaches the corresponding pressure trigger index, the pressure sensor will be lowered. The lowered pressure sensor can allow the balls to pass through the inner wall of the hose, and then the hose can quantitatively spit out the corresponding number of balls.

[0031] By setting corresponding preparation steps and adding pressure sensors, the function of quantitative transportation can be directly provided to the hose body through the pressure sensor, and a reserved installation position can be provided for the pressure sensor through the preparation steps of the hose, thereby avoiding as much as possible the technical problem that in the actual transportation of spherical workpieces such as balls, the hose is an one-piece molded pipe fitting in the preparation process. Due to the one-piece molding characteristics of the hose and the lack of corresponding quantitative transportation function, it is difficult for the hose body to grasp the actual transportation quality and quantity, and it is impossible to achieve a more precise quantitative transportation function.
