Description

Technical Field

[0001] The invention relates to the field of hose manufacturing, and in particular to production equipment and a process for an aluminum-plastic composite material telescopic hose. Background Art

[0002] In recent years, with the promotion and application of aluminum-plastic composite materials, aluminum-plastic composite telescopic hoses, especially aluminum foil composite film telescopic hoses, are popular among users because of their flexible tube walls, high pressure bearing capacity, small volume after compression, convenient transportation and use, and beautiful appearance. They are widely used in indoor ventilation, industrial dust removal systems, especially in household appliances such as kitchen range hoods and bathroom ventilators. When in use, in order to facilitate the assembly of the hose end and the interface of related equipment and to improve the contact strength and sealing of the interface, it is usually necessary to stick a reinforcing lining ring on the inner wall of the hose end.

[0003] In current production, the lining on the inner wall of the tube wall at the end of the telescopic hose is still applied manually, and the hose winding process, lining covering process, and pipe segment cutting process are not continuous in time sequence and workstation layout, and the semi-finished product has a long flow route between each process station. The existing common process flow is: the hose is wound and formed by a winding device, and after reaching a certain total length, the total length of the tube segment is cut off, and the tube segment is transferred from the winding station to another cutting station, and then the total length of the tube segment is cut to obtain a number of small tube segments that meet the required length. Then, each small tube segment is compressed separately, and then the compressed small tube segments are transferred to the corresponding station of the lining covering process. In the lining covering process station, the tube wall at the end of the small tube segment that is wrinkled due to compression is manually arranged to make it flat, and then the lining tape is manually curled into a lining and applied to the inner wall of the tube wall at the end of the small tube segment. The lining application is done manually, with a low degree of automation; the lining application quality is unstable; the operation time is long and the labor efficiency is low; the lining application and pipe segment cutting require additional labor teams and workstations, which increases the number of workers and work sites, and increases the corresponding management workload. The above production process affects the stability of hose production quality, the improvement of working conditions, and the improvement of production efficiency, and increases labor costs, re-product occupation costs, and production management costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is as follows: in order to solve the following problems: in order to solve the following problems: in the production process of the hose, the manual operation method of coating the liner on the inner wall of the hose end tube causes low operation efficiency and unstable operation quality; the hose winding process, the liner coating process, and the pipe section cutting process are not continuous, resulting in the non-compact workstations between the processes; the reworked products have a long circulation route between the workstations, the circulation time is long, the equipment and tooling occupy a large space; the labor force is large; the labor organization is complicated, etc. The present invention discloses a hose production equipment and process, which are used to realize the mechanization and automation of the liner coating on the inner wall of the hose end tube wall, and the integration of the hose winding process, the liner coating process, and the pipe section cutting process.

[0005] The technical idea of ​​the present invention is as follows: in the manufacturing process of the hose, the coating of the hose end wall liner and the cutting of the pipe section are automatically completed by the liner coating device and the pipe section cutting device in the equipment according to the corresponding process; the hose winding process, the liner coating process and the pipe section cutting process are organically integrated, and the specific process integration content is: first, the hose winding process starts, and the continuously wound hose is pushed forward; when the hose is pushed to the corresponding station on the line, the liner coating process is started, and the liner coating operation of the pipe wall is automatically completed by the liner coating device; then the pipe section cutting process is immediately executed, and the pipe section cutting device automatically completes the cutting of the pipe section with the liner attached. In this way, the dispersed hose winding process, the liner coating process and the pipe section cutting process are integrated into an overall continuous process line that is seamlessly connected in space and time, and the equipment automatically and once sequentially completes the inner wall liner coating and pipe section cutting of the hose, and obtains the finished pipe section with the liner attached on the inner wall of the end pipe wall.

[0006] The beneficial effects of the present invention are: improving the efficiency and quality of the hose lining and pipe segment cutting; realizing the automation and intensification of the overall process, which helps to shorten the length of the hose production process chain as a whole; reducing the number and volume of tooling; reducing the occupation of work; reducing labor; simplifying labor organization; improving labor conditions; improving productivity; and reducing production costs. At the same time, the equipment provided by the present invention has a high degree of integration and automation; a small volume; a simple structure, easy manufacturing and maintenance; reliable operation; and low manufacturing and use costs.

[0007] In order to realize the above technical ideas, the technical solution provided by the present invention is as follows:

[0008] 1. A hose production equipment, including a machine body, a hose winding device, a main drive assembly, a liner covering device, a pipe section cutting device, a glue coating device (optional), a liner conveying device, and a finished pipe section unloading device. The machine body is provided with a main mounting surface. The main mounting surface is composed of a physical surface on the machine body. The main mounting surface is centered around the main axis, and the main axis is located inside the main mounting surface surrounding it. The main axis is an imaginary geometric space straight line with a fixed position, which is physically realized by the axis geometric voxel of the main mounting surface surrounding it. The main axis is the main geometric reference datum for the spatial position and motion relationship of each component of the equipment, and its axial direction corresponds to the front and rear direction of the equipment. The hose winding device is mounted on the machine body. The main drive assembly is movably connected to the main mounting surface of the machine body. The main drive assembly is centered around the main axis. The liner covering device is mounted on the main drive assembly. The liner covering device is centered around the main axis. The liner covering device is located in front of the hose winding device and in the space area through which the hose passes when it is pushed forward. The main drive assembly supports and drives the liner covering device to move around the main axis. The hose winding device winds the tube wall of the hose, and the tube wall of the hose being wound rotates around the main axis. As the winding continues, the length of the hose continues to increase, and the front end of the hose leaves the hose winding device and is pushed forward along the main axis toward the liner covering device in front. The outline of the liner covering device loaded with the liner to be covered and the outline of other components carried by the main drive assembly, the maximum outer envelope diameter formed by the rotation of any outline around the main axis is smaller than the minimum inner wall envelope diameter formed by the rotation of the inner wall of the hose around the main axis, so the liner covering device can move unimpeded around the main axis inside the hose under the support and drive of the main drive assembly, and cover the carried liner on the inner wall of the hose. The pipe section cutting device cuts the hose covered with the liner, so that the inner wall of the end pipe wall of the cut finished pipe section is covered with the liner. The liner conveying device conveys the liner to the liner covering device. The finished pipe section unloading device moves the cut finished pipe section away from the current processing station.

[0009] Furthermore, the hose winding device is composed of a winding core mold, a main power mechanism, and a spiral groove pressing mechanism. The winding core mold is used to wind a hose with a cylindrical straight wall. The main power mechanism drives the winding core mold to operate. The spiral groove pressing mechanism can spin and press a spiral V-shaped groove on the cylindrical straight wall of the hose. The spiral V-shaped groove allows the hose to be easily compressed axially. The device can dynamically open and close the function of the spiral groove pressing mechanism to spin and press the spiral V-shaped groove.

[0010] The main driving assembly is composed of a first driving body, a second driving body, a first power mechanism, and a second power mechanism. The first driving body is movably connected to the main mounting surface of the machine body. The second driving body is movably connected to the first driving body. The first power mechanism is installed on the machine body. The first power mechanism drives the first driving body to move relative to the machine body. The second power mechanism is installed on the first driving body. The second power mechanism drives the second driving body to move relative to the first driving body. The second driving body can rotate and move axially around the main axis. The liner covering device is supported by the second driving body and moves synchronously with the second driving body.

[0011] The liner covering device is composed of a covering support base and a covering mechanism. The covering mechanism is installed on the covering support base. The covering mechanism moves to apply a force to the liner, and loads the received liner on the covering support base in a curled and contracted manner. After the liner is loaded, the maximum outer envelope diameter of the liner covering device is smaller than the minimum inner wall envelope diameter of the hose, and the liner covering device can move unhindered inside the hose. When covering the liner, the covering mechanism moves to apply a force to the liner, and radially expands the curled and contracted liner. The radially expanded liner is tightly covered on the inner wall of the hose. After the liner covering is completed, the covering mechanism breaks away from contact with the hose and performs a reset movement, so that the maximum outer envelope diameter of the liner covering device is smaller than the minimum inner wall envelope diameter of the hose, and the liner covering device is restored to an unhindered movement state inside the hose.

[0012] The pipe section cutting device is composed of a cutting support base, a cutting drive assembly, and a cutting tool. The cutting drive assembly is mounted on the cutting support base. The cutting tool is mounted on the cutting drive assembly. The cutting tool moves radially relative to the main axis under the support and drive of the cutting drive assembly. The radial movement is linked with the rotation of the hose relative to the pipe section cutting device, so that the cutting tool completes the circumferential cutting of the hose.

[0013] Furthermore, the coating support base, the cutting support base, and the second driving body are rigidly connected and combined together to form a triple motion synchronization body. The triple motion synchronization body forms a rigid combination entity to achieve synchronous motion. The triple motion synchronization body drives the liner coating device and the pipe section cutting device to rotate around the main axis centerline and move axially along the main axis centerline.

[0014] Further, the winding tire core mold is composed of a plurality of first winding roller assemblies and a plurality of second winding rollers. The first winding roller assembly and the second winding roller winding rollers are distributed in a circumferential array around the main axis centerline to form a squirrel cage-shaped winding tire core mold. The first winding roller assembly is composed of a first winding roller and a roller gear. The first winding roller and the roller gear are rigidly connected together. The roller gear is located at the rear end of the first winding roller. The first winding roller and the roller gear can be simplified as a part manufacturing unit. The angle formed by the axis centerline of the first winding roller and the axis centerline of the second winding roller in the circumferential direction of each winding main axis centerline and the main axis centerline is greater than 0 degrees, so that the wound hose is lengthened and pushed forward. The first winding roller and the second winding roller are rotatably connected to the machine body. The main power mechanism is composed of an intermediate gear, a transmission assembly, and a main drive motor. The intermediate gear is rotatably connected to the machine body and rotates around the main axis centerline. The intermediate gear is meshed with each roller gear located in its circumferential direction. The main drive motor is mounted on the machine body. The main driving motor drives the intermediate gear to rotate through the transmission assembly, and then the intermediate gear drives the meshed roller gears to rotate, thereby finally driving the first winding rollers to rotate. During operation, there is friction between the tube wall of the hose wound on the winding tire core mold and the outer circumferential surface of each rotating first winding roller. Under the action of the friction, the tube wall of the hose rotates around the main axis and moves forward. The second winding roller is driven to rotate by the tube wall of the hose. The rotational movement of the first winding roller and the rotational movement of the second winding roller are combined into the rotational movement of the winding tire core mold. The gear meshing structure is simple, the operation is reliable, and the service life is long; the transmission is accurate, and it is easy to accurately detect and control the equipment operation parameters and the relevant technical parameters of the hose.

[0015] The spiral groove pressing mechanism is composed of a pressurizing movable body, a movable groove pressing wheel, a separation drive assembly, and a fixed groove pressing wheel. The pressurizing movable body is movably connected to the machine body, and the separation drive assembly can drive the pressurizing movable body to move relative to the machine body to dynamically open and close the groove pressing function of the spiral groove pressing mechanism. The movable groove pressing wheel is rotatably connected to the pressurizing movable body. The outer circumferential surface of the movable groove pressing wheel is an annular V-shaped convex surface. The fixed groove pressing wheel is rigidly connected to the front end of a second winding roller and is combined with the second winding roller to form a motion synchronous body. The fixed groove pressing wheel and the second winding roller can be simplified into a parts manufacturing unit. The outer circumferential surface of the fixed groove pressing wheel is an annular V-shaped concave surface. The pressurizing movable body can move relative to the machine body under the action of external force, drive the movable groove pressing wheel to approach the fixed groove pressing wheel, and stop at the groove pressing position due to the obstruction of the fixed groove pressing wheel. At the groove pressing position, the annular V-shaped convex surface of the movable groove pressing wheel is tangent to the annular V-shaped concave surface of the fixed groove pressing wheel, and the two tangent surfaces form a concave-convex mold matching relationship in the plane where the axis of the movable groove pressing wheel and the axis of the fixed groove pressing wheel are colinear. The pressurizing movable body moves relative to the body under the action of the separation drive assembly, driving the movable groove pressing wheel to disengage from the groove pressing position and stop at the separation position. When grooving the hose wall, at the groove pressing position, the annular V-shaped convex surface of the movable groove pressing wheel presses the contacted pipe wall from the outer side of the hose pipe wall under the action of external force on the annular V-shaped concave surface of the fixed groove pressing wheel located on the inner side of the pipe wall, and utilizes the concave-convex mold pressing relationship formed by the annular V-shaped concave surface of the fixed groove pressing wheel and the annular V-shaped convex surface of the movable groove pressing wheel, and accompanies the rotation and forward advancement of the pipe wall, and a spiral V-shaped groove is spun on the hose pipe wall. The spiral V-shaped groove allows the hose to be easily compressed axially. When the movable groove pressing wheel is separated from the groove pressing position and finally stops at the separation position, the groove pressing operation of the hose tube wall is terminated, and the hose tube wall subsequently wound recovers to a cylindrical straight wall shape.

The liner conveying device is composed of a fixed support body and a feeding mechanism. The fixed support body is solidly connected to the machine body. In manufacturing, the fixed support body can be manufactured together with the machine body as a part of the structural feature of the machine body. The feeding mechanism is composed of a guide groove body, a push drive assembly and a transposition drive assembly. The push drive assembly is installed on the guide groove body.

[0025] S1. Bushing preparation:

[0026] The liner can be an integrally formed seamless annular liner or a liner formed by curling a strip-shaped sheet and overlapping the ends.

[0027] Furthermore, if a head-to-tail overlapping liner is used, the length of the strip sheet should be such that when the strip sheet is rolled into a liner and attached to the inner wall of the hose, the head and tail of the strip sheet have a required overlapping length in the circumferential direction.

[0028] The front end of the strip is processed with a first pulling process hole, and the rear end is processed with a second pulling process hole.

[0030] S2. Making the first straight wall section of the hose:

[0031] The winding tire core mold of the hose winding device is started to operate, and the hose begins to be wound.

During this process, the groove pressing function is turned off, the movable groove pressing wheel is in the separation position, and the hose wall of the wound hose is in a cylindrical straight wall shape, and the spiral V-shaped groove is not spun. When the front end of the hose is pushed to the first limit, the groove pressing function is turned on, and the movable groove pressing wheel is controlled to move from the separation position to the groove pressing position. The movable groove pressing wheel presses the hose wall from the outside of the hose on the fixed groove pressing wheel inside the hose, and starts to spin the spiral V-shaped groove on the hose wall from this position. When the front end of the hose crosses the first limit and advances to the second limit, the operation of the winding tire core mold is suspended.

[0032] The hose section at the front end of the hose that has not been spun with a spiral V-groove is called the first straight wall section, and its wall is cylindrical and straight, which is convenient for pasting a liner on the inner wall of this section of the hose.

[0062] When the front end of the hose is pushed to the fourth limit, the groove pressing function is turned on, and the movable groove pressing wheel is controlled to move from the separation position to the groove pressing position, and the spiral V-shaped groove is pressed on the hose wall again, and the preparation of the third straight wall section is also completed. The prepared third straight wall section has a cylindrical straight wall shape, which is convenient for pasting the lining ring on the inner wall of this section of the wall.

[0063] When the front end of the hose is pushed to the fifth limit, the operation of the winding tire core mold is suspended, and the third straight wall section has been pushed into the pasting and cutting station area, and the third straight wall section is in a position that crosses the cutting surface, that is, the two ends of the third straight wall section are respectively in front of and behind the cutting surface.

[0067] S12, cutting the second finished pipe section:

[0068] The main drive assembly and the pipe section cutting device are controlled so that the cutting tool located inside the hose cuts the third straight wall section along the cutting surface, and the third straight wall section is divided into the front half of the third straight wall section and the rear half of the third straight wall section. The cut pipe section is called the second finished pipe section. The second finished pipe section includes three parts in a front-to-back order: the rear half of the second straight wall section, the second telescopic section, and the front half of the third straight wall section. The inner walls of the pipe walls at the front and rear ends of the second finished pipe section are both covered with bushings.

[0071] S14, loop through steps S9 to S13 to repeatedly obtain the second finished pipe segment.

[0072] The present invention distinguishes between describing the manufacturing processes of the first finished pipe segment and the second finished pipe segment because the manufacturing of the first finished pipe segment starts from the initial winding of the hose wall that is not covered with the inner wall liner; and the manufacturing of the second finished pipe segment starts from the hose wall that has been covered with the inner wall liner; so the present invention first describes the manufacturing process of the first finished pipe segment as a prerequisite for the manufacturing of the second finished pipe segment in a process logic order, and then describes the manufacturing process of the second finished pipe segment; it should be understood that the first finished pipe segment and the second finished pipe segment respectively represent two types of hose products under different initial conditions of the manufacturing process; and it should be further understood that the first boundary, the second boundary, the third boundary, the fourth boundary, the fifth boundary, and the cutting surface, a series of imaginary geometric planes, are intended to describe the different staying positions of the hose in the forward advancement process during the manufacturing process; in In actual production, in order to meet the different needs of users, the length dimensions of the first finished pipe section or the second finished pipe section of each case may be different. Therefore, when preparing the first finished pipe section or the second finished pipe section of each case, the first boundary, the second boundary, the third boundary, the fourth boundary, the fifth boundary, the cutting surface, and a series of imaginary geometric planes, the specific distance dimensions between each other, including the distance dimensions relative to the equipment, may be different from those of the first finished pipe section or the second finished pipe section of other cases; but corresponding to the finished pipe section itself of each case, the first boundary, the second boundary, the third boundary, the fourth boundary, the fifth boundary, the cutting surface, and a series of imaginary geometric planes, the front-to-back relative position relationship between each other, and the front-to-back relative position relationship with the equipment, remain unchanged during the preparation process of the finished pipe section of each case. Furthermore, the first boundary is located in front of the second boundary, which only qualitatively describes the order of the two positions and has nothing to do with the specific distance between the two. Therefore, it should be understood that each case of the first finished pipe segment and each case of the second finished pipe segment do not necessarily share a set of imaginary geometric planes having a fixed mutual distance, namely the first boundary, the second boundary, the third boundary, the fourth boundary, the fifth boundary, and the cutting surface.

[0111] 1. Please refer to Figure 1 to Figure 29 A hose production device according to an embodiment of the present invention is composed of a machine body 1000, a hose winding device 2000, a main drive assembly 3000, a liner coating device 40000, a pipe section cutting device 5000, a glue coating device 6000, a liner conveying device 7000, and a finished pipe section unloading device 80000.

[0112] like Figure 5 As shown, a main hollow shaft extension 1100 extending backward is provided on the body 1000, and the main hollow shaft extension 1100 has a main hollow shaft extension inner circular surface and a main hollow shaft extension outer circular surface 1120. The cavity space contained in the main hollow shaft extension inner circular surface is through-connected from front to back. The axis center line shared by the main hollow shaft extension inner circular surface and the main hollow shaft extension outer circular surface 1120 is set as the main axis center line 0001. The main hollow shaft extension inner circular surface is set as the main mounting surface 1110. A guide keyway 1130 is set between the main hollow shaft extension inner circular surface and the main hollow shaft extension outer circular surface 1120 of the main hollow shaft extension 1100, and the guide direction is the axial direction of the main axis center line 0001.

[0113] like Figure 1 to Figure 6 , Fig. 9 , Fig.11 As shown, the hose winding device 2000 is composed of a winding tire core mold 2100, a main power mechanism 2200, and a spiral groove pressing mechanism 2300. Fig.30 As shown in FIG. 2 , a hose 20000 having a cylindrical straight wall is wound by a rotating tire core mold 2100. The main power mechanism 2200 drives the rotating tire core mold 2100 to operate. Fig.37 , Fig.47 As shown, the spiral groove pressing mechanism 2300 can spin out a spiral V-shaped groove 21000 on the cylindrical straight wall of the hose 20000. The spiral V-shaped groove 21000 allows the hose 20000 to be conveniently compressed axially.

[0114] The winding tire core mold 2100 is composed of 8 first winding roller assemblies 2110 and 1 second winding roller 2120. The 8 first winding roller assemblies 2110 and 1 second winding roller 2120 are distributed in a circular array around the main axis 0001, forming a squirrel cage-shaped winding tire core mold 2100. The first winding roller assembly 2110 is composed of a first winding roller 2111 and a roller gear 2112. The first winding roller 2111 and the roller gear 2112 are solidly connected together. The roller gear 2112 is located at the rear end of the first winding roller 2111. The first winding roller 2111 and the roller gear 2112 can be simplified as a part manufacturing unit. The first winding roller axis 0002 and the second winding roller axis 0003, both of which have an angle greater than 0 degree with the main axis 0001 in the circumferential direction of the winding main axis 0001. The first winding roller 2111 and the second winding roller 2120 are rotatably connected to the machine body 1000, and the rotatable connection can be realized by means of sliding bearings, rolling bearings, etc. There is friction between the tube wall of the hose 20000 wound on the winding tire core mold 2100 and the outer circumferential surface of each rotating first winding roller 2111. Driven by the friction, the tube wall of the hose 20000 rotates around the main axis 0001 and moves forward. The second winding roller 2120 is also driven to rotate by the tube wall of the hose 20000 due to the friction. The rotational motion of the first winding roller 2111 and the rotational motion of the second winding roller 2120 are combined into the rotational motion of the winding tire core mold 2100.

[0115] The main power mechanism 2200 is composed of an intermediate gear 2210, a transmission assembly 2220, and a main drive motor 2230. The intermediate gear 2210 is rotatably connected to the outer cylindrical surface 1120 of the main hollow shaft extension 1100 on the body 1000, and the rotatable connection can be realized by means of sliding bearings, rolling bearings, etc. The intermediate gear 2210 is meshed with each roller gear 2112 located in its circumferential direction. The transmission assembly 2220 includes a first gear 2221 and a second gear 2222. The first gear 2221 is solidly connected to the power output shaft of the main drive motor 2230, and the second gear 2222 is rotatably connected to the body 1000. The first gear 2221 is meshed with the second gear 2222, and the second gear 2222 is meshed with the intermediate gear 2210. The second gear 2222 provided in this embodiment can be used to drive the motion sensor device of the electrical control system to realize the detection and control of the rotational motion of the hose winding device 2000. The main driving motor 2230 is mounted on the machine body 1000. The main driving motor 2230 drives each first winding roller 2111 to rotate through the gear meshing between the first gear 2221 and the second gear 2222, the gear meshing between the second gear 2222 and the intermediate gear 2210, and the gear meshing between the intermediate gear 2210 and each roller gear 2112.

[0116] The spiral groove pressing mechanism 2300 is composed of a pressurizing movable body 2310, a movable groove pressing wheel 2320, a separation drive assembly 2330, and a fixed groove pressing wheel 2340. The pressurizing movable body 2310 is slidably connected to the machine body 1000. The movable groove pressing wheel 2320 is rotatably connected to the pressurizing movable body 2310. The outer circumferential surface of the movable groove pressing wheel 2320 is an annular V-shaped convex surface 2321. The fixed groove pressing wheel 2340 is rigidly connected to the front end of the second winding roller 2120, and is combined with the second winding roller 2120 to form a motion synchronization body. The manufacturing of the fixed groove pressing wheel 2340 and the second winding roller 2120 can be simplified into a part manufacturing unit. The outer circumferential surface of the fixed groove pressing wheel 2340 is an annular V-shaped concave surface 2341. The separation drive assembly 2330 is composed of a separation drive 2331 and a pressurizing spring 2332. The separation drive 2331 is installed on the machine body 1000. As shown Fig. 9 , Fig.10 As shown, the two ends of the pressure spring 2332 are respectively connected to the body 1000 and the pressure movable body 2310, and the pressure spring 2332 applies a pulling force to the pressure movable body 2310, pulling the pressure movable body 2310 to slide to the lower left. The separation driver 2331 can drive the pressure movable body 2310 to overcome the pulling force of the pressure spring 2332 and slide to the upper right.

[0117] like Fig. 9 , Fig.10 , Figure 36 to Figure 38As shown, when the pressurizing movable body 2310 slides to the lower left under the pulling force of the pressurizing spring 2332, it drives the movable groove pressing wheel 2320 to approach the fixed groove pressing wheel 2340, and finally stops at the groove pressing position P12 due to the blocking of the fixed groove pressing wheel 2340. At the groove pressing position P12, the annular V-shaped convex surface 2321 of the movable groove pressing wheel 2320 is tangent to the annular V-shaped concave surface 2341 of the fixed groove pressing wheel 2340, and the two tangent surfaces form a concave-convex mold matching relationship in the plane where the axis of the movable groove pressing wheel 2320 and the axis of the fixed groove pressing wheel 2340 are colinear. Under the drive of the separation driver 2331, the pressurizing movable body 2310 can overcome the pulling force of the pressurizing spring 2332 and slide to the upper right, driving the movable groove pressing wheel 2320 to leave the groove pressing position P12, and finally stop at the separation position P11. When grooving the tube wall of the hose 20000, at the grooving position P12, the annular V-shaped convex surface 2321 of the movable grooving wheel 2320, under the pulling force of the pressure spring 2332, presses the tube wall against the annular V-shaped concave surface 2341 of the fixed grooving wheel 2340 located at the inner side of the tube wall from the outer side of the tube wall of the hose 20000, forming a concave-convex mold matching relationship for squeezing the tube wall, and with the rotation and forward advancement of the tube wall, a spiral V-shaped groove 21000 is spun on the cylindrical straight wall of the hose 20000, so as to facilitate the axial compression of the hose 20000. When the movable grooving wheel 2320 is separated from the grooving position P12 and finally stops at the separation position P11, the grooving operation of the tube wall of the hose 20000 is terminated, and the tube wall of the wound hose 20000 is then restored to a cylindrical straight wall shape. The separation driver 2331 is controlled to dynamically open and close the groove pressing function to cooperate with the liner covering.

[0118] like Figure 1 As shown, the main driving assembly 3000 is composed of a first driving body 3100 , a second driving body 3200 , a first power mechanism 3300 , and a second power mechanism 3400 .

[0119] like Figure 5 As shown, the first driving body 3100 and the second driving body 3200 are both hollow tubular structures, wherein the first driving body 3100 is provided with a first driving body inner circular surface 3110 and a first driving body outer circular surface 3120; the second driving body 3200 is provided with a second driving body inner circular surface 3210 and a second driving body outer circular surface 3220.

[0120] like Figure 1 As shown, the first power mechanism 3300 is composed of a first power motor 3310, a first power support 3320, a first power gear 3330, and a first power rack 3340. The second power mechanism 3400 is composed of a second power motor 3410, a second power support 3420, a second power gear 3430, and a second driven gear 3440.

[0121] like Figure 5 , Fig.11 As shown, the first driving body 3100 is solidly connected with the first power rack 3340. The outer cylindrical surface 3120 of the first driving body 3100 and the main mounting surface 1110 on the body 1000 form a cylindrical movable connection pair, and the first power rack 3340 and the guide keyway 1130 on the body 1000 form a front-to-back sliding guide connection pair, which restricts the first driving body 3100 from rotating relative to the body 1000 around the main axis 0001. Under the combined action of the above-mentioned cylindrical movable connection pair and the front-to-back sliding guide connection pair, the first driving body 3100 movably connected to the main mounting surface 1110 of the body 1000 can only move forward and backward relative to the body 1000, that is, move axially along the axis 0001.

[0122] like Figure 5 , Fig.11 As shown, the second driving body 3200 forms a cylindrical rotation connection pair with the first driving body 3100's inner circular surface 3110 through the second driving body outer circular surface 3220, and the second driving body 3200 is rotationally connected to the first driving body 3100 through the cylindrical rotation connection pair, that is, the second driving body 3200 can only rotate around the main axis 0001 relative to the first driving body 3100. When the first driving body 3100 moves in the front and rear direction relative to the machine body 1000, the second driving body 3200 can move forward and backward synchronously therewith. The linkage between the front and rear movement of the first driving body 3100 relative to the machine body 1000 and the rotation of the second driving body 3200 relative to the first driving body 3100 enables the second driving body 3200 to rotate and move axially relative to the machine body 1000 with the main axis 0001 as the center.

[0123] like Fig.11 As shown, the first power support 3320 is solidly connected to the rear end of the main hollow shaft extension 1100, the first power motor 3310 is installed on the first power support 3320, and the first power gear 3330 is solidly connected to the power output shaft of the first power motor 3310. The first power gear 3330 is meshed with the first power rack 3340, and through the meshing of the gear rack, the first power motor 3310 drives the first driving body 3100 to move forward and backward relative to the body 1000.

[0124] like Figure 5As shown, the second power support 3420 is solidly connected to the rear end of the first driving body 3100, the second power motor 3410 is installed on the second power support 3420, and the second power gear 3430 is solidly connected to the power output shaft of the second power motor 3410. The second driven gear 3440 is solidly connected to the rear end of the second driving body 3200. The second power gear 3430 is meshed with the second driven gear 3440, and through the gear meshing, the second power motor 3410 drives the second driving body 3200 to rotate around the main axis 0001 relative to the first driving body 3100.

[0125] like Figure 2 , Figure 12 to Figure 14 As shown, the liner coating device 40000 is composed of a coating support substrate 41000 and a coating mechanism 42000.

[0126] like Figure 12 to Figure 14 As shown, the covering support base 41000 is provided with a supporting arc surface 41100, an outer cylindrical surface shaft extension 41200, a lining belt feeding port 41300, and an arc-shaped T-shaped cross-section cavity 41400. The common axis of the supporting arc surface 41100, the arc-shaped T-shaped cross-section cavity 41400 and the outer cylindrical surface shaft extension 41200 coincides with the main axis 0001. Fig.24 , Fig.25 As shown, the supporting arc surface 41100 is used to wrap the strip sheet 9000 in a curled and contracted annular ring manner and apply it thereon. Fig.12 As shown, the arc-shaped T-shaped cross-section cavity 41400 is located radially inside between the two axial ends of the supporting arc surface 41100. Fig.24 As shown, when the strip sheet 9000 is wrapped and attached to the supporting arc surface 41100 in a curled and contracted annular ring, the front end of the strip sheet 9000 at the overlapping position is placed in the arc-shaped T-shaped cross-section cavity 41400. The arc-shaped T-shaped cross-section cavity 41400 also provides a space for the relevant operating components of the attaching mechanism 42000 to move. Fig.13 , Fig.14 , Figure 21 to Figure 24 As shown, a lining tape feeding inlet 41300 is provided on the supporting arc surface 41100, and the lining tape feeding inlet 41300 is connected to the arc-shaped T-shaped cross-section cavity 41400.

The hose 20000 being wound rotates around the main axis 0001, and the length is continuously lengthened. The front end of the hose 20000 moves forward, leaves the winding tire core mold 2100 and enters the area where the spiral groove pressing mechanism 2300 is located. When the movable groove pressing wheel 2320 is at the groove pressing position P12, the spiral groove pressing mechanism 2300 spins out a spiral V-shaped groove 21000 on the cylindrical straight wall of the hose 20000. The grooved hose 20000 continues to move forward and enters the station area where the liner coating device 40000, the glue coating device 6000, and the pipe section cutting device 5000 are located. The lining coating device 40000, the glue coating device 6000, and the pipe section cutting device 5000 are assembled and installed on the front end of the main driving assembly 3000 through the triple motion synchronization body 8000; the rear end of the main driving assembly 3000 is connected to the body 1000 in a forward and backward moving manner. The liner coating device 40000, the pipe section cutting device 5000, the glue coating device 6000 and the main driving assembly 3000, these four components are combined together to form a whole contour whose maximum outer contour envelope diameter K formed by rotating relative to the main axis centerline 0001 is smaller than the minimum inner wall envelope diameter N formed by the inner wall of the tube wall of the hose 20000 relative to the main axis centerline 0001, and the spatial area contained in the maximum outer contour envelope diameter K is completely within the spatial area contained in the minimum inner wall envelope diameter N. Therefore, the liner coating device 40000, the pipe section cutting device 5000 and the glue coating device 6000 can be supported and driven by the main driving assembly 3000, and can rotate and move axially unimpeded around the main axis centerline 0001 inside the hose 20000, and then complete the glue coating, liner coating and pipe section cutting process operations.

[0145] like Fig.19 , Fig. 20 As shown, this embodiment uses a lining ring 10000 formed by curling a strip-shaped sheet 9000 and overlapping the ends. Figure 21 to Figure 25As shown, the liner conveying device 7000 and the liner coating device 40000 cooperate with each other to construct a transition channel for conveying the strip sheet 9000 into the liner coating device 40000, and assist in winding the strip sheet 9000 in a curled and shrunk annular ring manner and coating it on the supporting arc surface 41100 of the liner coating device 40000.

The guide groove cavity 7211 plays a positioning and guiding role in the transportation of the strip-like sheet 9000 placed therein. A discharge port 7212 and a contact pressure positioning surface 7213 are provided at the end of the guide groove cavity 7211 along the discharge direction of the strip-like sheet 9000, and the discharge port 7212 and the contact pressure positioning surface 7213 are connected together. The contact pressure positioning surface 7213 can exert a limiting effect on the strip-like sheet 9000. The guide groove body transposition inner circular hole 7214 is rotatably connected to the cylindrical surface of the cylindrical shaft extension of the fixed support body 7100, so that the guide groove body 7210 can rotate relative to the fixed support body 7100, thereby changing its position between the loading alignment position P1 and the guide groove body avoidance position P2, as shown in FIG. Figure 7 shown.

[0150] like Figure 1 , Figure 3 As shown, the pusher drive assembly 7220 is composed of a pusher drive motor 7221, a pusher drive wheel 7222, a drive pressure wheel 7223, and a drive pressure wheel seat 7224.

The drive pressure wheel 7223 is rotatably connected to the drive pressure wheel seat 7224. The drive pressure wheel seat 7224 is slidably connected to the guide slot body 7210. The pusher drive wheel 7222 is connected to the power output shaft of the pusher drive motor 7221, and the pusher drive motor 7221 drives the pusher drive wheel 7222 to rotate. Fig.21As shown, the driving pressure wheel 7223 presses the strip sheet 9000 onto the pushing driving wheel 7222 under the action of external force. Under the rotation of the pushing driving wheel 7222, the strip sheet 9000 in the guide groove cavity 7211 is transported to the liner coating device 40000 through the discharge port 7212.

[0151] like Figure 1 , Figure 7 As shown, the transposition drive assembly 7230 is composed of a transposition drive 7231 and a drive seat 7232. The drive seat 7232 is rigidly connected to the fixed support body 7100, and the transposition drive 7231 is installed on the drive seat 7232. The drive seat 7232 drives the guide slot body 7210 to rotate.

[0152] 2. Please refer to Figure 18 to Figure 47 A hose production process according to an embodiment of the present invention is implemented in cooperation with the above-mentioned production equipment, and includes the following steps:

[0153] S1. Preparation of liner 10000:

[0154] like Figures 18 to 20 As shown, this embodiment adopts a liner 10000 formed by curling a strip sheet 9000 and overlapping the ends. The length of the strip sheet 9000 should satisfy the requirement that when the strip sheet 9000 is curled into a liner and attached to the inner wall of the tube wall of the hose 20000, the ends of the strip sheet 9000 have an overlapping length in the circumferential direction that meets the requirements.

[0155] like Fig.18 As shown, the front end of the strip-shaped sheet 9000 is processed with a first pulling process hole 9100, and the rear end is processed with a second pulling process hole 9200. The second pulling process hole 9200 is divided into a second pulling through hole 9210 and a second pulling locking hole 9220 that are interconnected. The pulling hook of the lining ring covering device 40000 hooks the pulling process hole, applies a force to the strip-shaped sheet 9000, and pulls and drives the strip-shaped sheet 9000 to complete the relevant operation.

[0156] like Figures 18 to 20 As shown, the front end of the strip-shaped sheet 9000 is processed with a convex overlapping tenon 9300, and the rear end is processed with a concave overlapping tenon 9400. During the covering operation, the lining ring covering device 40000 uses the convex overlapping tenon 9300 and the concave overlapping tenon 9400 on the strip-shaped sheet 9000 to form a tenon overlap at the head and tail of the lining ring 10000. The tenon overlap structure can prevent the lining ring 10000 covered by the hose 20000 from loosening at the head and tail connection, so that the lining ring 10000 can be tightly covered on the inner wall of the hose 20000.

[0157] S2. Producing the first straight wall section D1 of the hose 20000:

[0158] like Fig.30 As shown, the winding core mold 2100 of the hose winding device 2000 is started to operate and the hose 20000 begins to be wound.

The movable grooving wheel 2320 presses the tube wall from the outside of the hose 20000 onto the fixed grooving wheel 2340 inside the hose, and begins to spin-press the spiral V-shaped groove 21000 on the cylindrical straight-walled tube wall.

[0160] like Fig.32 As shown in FIG. 1 , when the front end of the hose 20000 passes the first limit X1 and advances to the second limit X2, the operation of the spinning tire core mold 2100 is stopped.

The wall of the third straight wall section D7 is cylindrical and straight, which is convenient for the lining ring 10000 to be attached to the inner wall of this section of the wall.

[0193] The winding of hose 20000 continues. Fig.44 As shown, when the front end of the hose 20000 is pushed to the fifth limit X5, the operation of the rotating tire core mold 2100 is suspended. At this time, the third straight wall section D7 has been pushed into the pasting and cutting station area Q1, and the third straight wall section D7 is in a position spanning the cutting surface P14, that is, the two ends of the third straight wall section D7 are respectively in front of and behind the cutting surface P14.

[0194] S11, pasting the liner 10000 on the inner wall of the third straight wall section D7:

[0195] like Fig.44 As shown, the second driving body 3200 is controlled to move axially along the main axis 0001 to send the glue coating device 6000 to the glue coating position inside the third straight wall section D7, and then the second driving body 3200 drives the glue coating device 6000 to rotate around the main axis 0001. During the rotation, the glue coating device 6000 performs glue coating 30000 operation on the inner wall of the third straight wall section D7.

[0196] like Fig.45 As shown, the second driving body 3200 is controlled to move axially along the main axis 0001, and the liner pasting device 40000 is sent to the liner pasting position inside the third straight wall section D7. The liner pasting device 40000 carrying the strip sheet 9000 performs a liner pasting 50000 operation on the inner wall of the third straight wall section D7, and the strip sheet 9000 is overlapped head to tail (such as the liner pasting method) Fig. 20 , Fig. 27 As shown) is attached to the inner wall of the tube.

[0197] S12, cutting the second finished pipe section D11:

[0198] like Fig.46 As shown, the second driving body 3200 is controlled to move axially along the main axis 0001, and the cutting tool 5300 of the pipe section cutting device 5000 is sent to the cutting surface P14 position spanned by the third straight wall section D7, so that the cutting tool 5300 cuts the third straight wall section D7 along the cutting surface P14, and divides the third straight wall section D7 into the third straight wall section front half D9 and the third straight wall section rear half D10. The cut pipe section is called the second finished pipe section D11, which is composed of three parts from front to back, namely, the second straight wall section rear half D5, the second telescopic section D8 and the third straight wall section front half D9. The inner walls of the front and rear ends of the second finished pipe section D11 are both covered with bushings 10000, but the bushings 10000 at both ends are half of the complete bushing 10000 after being cut along the width direction.

[0199] S13, moving the second finished pipe segment D11 away from the current processing station.

[0200] Operate the finished pipe segment unloading device 80000 to move the second finished pipe segment D11 away from the current processing station.

[0201] S14, loop through steps S9 to S13 to repeatedly obtain the second finished pipe segment D11.

[0202] The following, in conjunction with the relevant drawings, further illustrates the specific operation process of loading the strip sheet 9000 into the liner covering device 40000 via the liner conveying device 7000 in the process steps S4 and S9 of the embodiment, and the specific operation process of the liner covering device 40000 covering the liner 10000 on the inner wall of the hose 20000 in the process steps S3, S6, and S11 of the embodiment, and further clarifies the actions and coordination relationships of the relevant operating components of the main drive assembly 3000, the liner conveying device 7000, and the liner covering device 40000.

[0203] like Fig.21 , Fig. 22 , Fig.35As shown, in order to load the strip-shaped sheet 9000 into the liner coating device 40000 through the liner conveying device 7000, the second driving body 3200 is controlled to move axially along the main axis 0001 to deliver the liner coating device 40000 to the liner feeding inlet and the discharge outlet of the liner conveying device 7000 in the liner loading station area Q2. The liner feeding inlet 4000 of the liner coating device 40000 is aligned with the discharge outlet. At this position, the liner feeding inlet 4000 of the liner coating support substrate 41000 is aligned with the discharge outlet of the liner conveying device 7000. 1300 is aligned with the discharge port 7212 on the guide groove body 7210 of the lining ring conveying device 7000 in the front-to-back direction (i.e., the axial direction of the main axis centerline 0001). The alignment at this position means that the center plane of the width of the lining tape feeding port 41300 in the front-to-back direction coincides with the center plane of the width of the discharge port 7212 in the front-to-back direction. The coincidence plane is an imaginary geometric plane perpendicular to the main axis centerline 0001, that is, the front-to-back alignment position P13 of the lining tape feeding port and the discharge port. When the alignment of the lining tape feeding port 41300 and the discharge port 7212 at this position and the alignment of the lining tape feeding port 41300 and the discharge port 7212 in the up-down and left-right directions of the loading alignment position P1 to be described below are met at the same time, it can be ensured that the strip sheet 9000 can smoothly pass through the transition channel where the discharge port 7212 and the lining tape feeding port 41300 are connected, and be loaded from the lining ring conveying device 7000 onto the lining ring coating device 40000.

[0204] like Figure 7 , Fig.21 , Fig. 22 As shown, after the lining band coating device 40000 is sent to the front-to-back alignment position P13 between the lining band feeding port and the material outlet by the second driving body 3200, the displacement driver 7231 of the lining band conveying device 7000 is operated to drive the guide groove body 7210 to rotate from the guide groove body avoidance position P2 to the material loading alignment position P1 around the fixed support body 7100. The second driving body 3200 is operated to rotate around the main axis 0001, driving the lining band coating device 40000 to rotate together, and rotating the lining band feeding port 41300 on the coating support base 41000 to the alignment position with the material outlet 7212 on the guide groove body 7210 in the up-down and left-right directions, as shown in FIG. Fig.21As shown, in this alignment position, the front end of the strip sheet 9000 sent out from the discharge port 7212 can be accurately positioned in the lining tape feed port 41300, and can be pulled into the arc-shaped T-shaped cross-section cavity 41400 through the lining tape feed port 41300. The strip sheet 9000 in the guide groove cavity 7211 of the guide groove body 7210 is pressed on the driving push drive wheel 7222 by the driving pressure wheel 7223. The push drive motor 7221 is controlled to operate, and the push drive motor 7221 drives the push drive wheel 7222 to rotate. Relying on the friction between the driving push drive wheel 7222 and the strip sheet 9000, the strip sheet 9000 is pushed to move from left to right along the guide groove cavity 7211, and the front end of the strip sheet 9000 is sent out of the discharge port 7212 to the lining tape feed port 41300. When the first pulling process hole 9100 at the front end of the strip-shaped sheet 9000 reaches the first pulling hook position P3, the operation of the material pushing drive motor 7221 is stopped. The first pulling mechanism 42100 of the lining ring laminating device 40000 is controlled to make the first pulling hook 42130 move to the first pulling hook position P3 driven by the first movable body 42120, at which position the first pulling hook 42130 passes through the first pulling process hole 9100 at the front end of the strip-shaped sheet 9000, completing the hanging of the first pulling process hole 9100.

[0205] like Fig.23 As shown, the first pulling mechanism 42100 is controlled so that the first pulling hook 42130, driven by the first movable body 42120, pulls the first pulling process hole 9100 from the first pulling hook position P3 to rotate counterclockwise around the main axis 0001, enter the arc-shaped T-shaped cross-section cavity 41400, and finally stop at the first pulling shrinking circle position P4. The front end of the strip-shaped sheet 9000 is pulled into the arc-shaped T-shaped cross-section cavity 41400 to solve the problem that when the strip-shaped sheet 9000 is wound on the supporting arc surface 41100 in a curled and shrunk annular ring, the redundant length of the overlapping part of the head and tail has space to be accommodated.

[0206] like Figure 24 to Figure 26As shown, the second driving body 3200 is controlled to rotate counterclockwise around the main axis 0001, driving the covering support base 41000 to rotate counterclockwise synchronously, and the remaining part of the strip sheet 9000 is pulled out from the guide groove body 7210 and wound on the supporting arc surface 41100. In the process of the strip sheet 9000 winding on the supporting arc surface 41100, the contact and pressure positioning surface 7213 of the guide groove body 7210 exerts a limiting effect on the strip sheet 9000 at the discharge port 7212. When the second pulling process hole 9200 at the rear end of the strip sheet 9000 moves to the second pulling circumferential hooking position P5, the strip sheet 9000 has been completely pulled out of the guide groove cavity 7211 from the discharge port 7212. Due to the limiting effect of the contact and pressure positioning surface 7213 on the rear end of the strip-shaped sheet 9000, the second pulling process hole 9200 can be correctly maintained at the second pulling circumferential hooking position P5. The second pulling mechanism 42200 is controlled to make the second pulling hook 42240 rotate and move axially relative to the main axis 0001 under the drive of the third movable body 42230 until it moves to the second pulling circumferential hooking position P5 in the up-down and left-right directions and the second pulling front-back hooking position P6 in the front-back direction, thereby realizing the second pulling hook 42240 passing through the second pulling hole 9210 of the second pulling process hole 9200. Then the third movable body 42230 is manipulated to drive the second pulling hook 42240 to move from the second pulling front and rear hooking position P6 to the second pulling hook locking position P7 in the front-back direction (i.e., the axial direction of the main axis 0001), where the second pulling hook 42240 hooks the second pulling locking hole 9220 of the second pulling process hole 9200. The second pulling hook 42240 and the second pulling locking hole 9220 are precision matched with a small gap, and the position of the concave overlapping tenon 9400 at the rear end of the strip-like sheet 9000 can be accurately located based on the position of the second pulling hook 42240, so as to achieve the overlapping of the head and tail tenons of the strip-like sheet 9000 more accurately; and when the second pulling hook 42240 hooks the second pulling locking hole 9220, it can prevent the strip-like sheet 9000 from being unhooked from the second pulling process hole 9200. At this point, the strip sheet 9000 is wound on the supporting arc surface 41100 in a curled and contracted annular ring manner, and the maximum outer envelope diameter K formed by the liner covering device 40000 rotating around the main axis 0001 is smaller than the minimum inner wall envelope diameter N.

[0207] like Figure 7 As shown, the shift driver 7231 of the liner conveying device 7000 is operated to drive the guide groove body 7210 to rotate around the fixed support body 7100 from the loading alignment position P1 to the guide groove body avoidance position P2, providing an avoidance space for the liner coating device 40000 to leave the liner belt feeding inlet and the front and rear alignment position P13 of the discharge port.

[0208] like Figure 27 to Figure 29As shown, when the bushing 10000 is attached to the inner wall of the hose 20000, the second pulling mechanism 42200 is controlled so that the second pulling hook 42240 is driven by the third movable body 42230 to move to the second pulling and expanding circle position P10 in the up and down and left and right directions. At this time, the second pulling hook 42240 is hooked on the second pulling locking hole 9220 of the second pulling process hole 9200, so the concave lap joint 9400 at the rear end of the strip sheet 9000 can be positioned at the required position more accurately. The first pulling mechanism 42100 is manipulated so that the first pulling hook 42130, driven by the first movable body 42120, pulls the first pulling process hole 9100 to the first pulling and expanding circle position P8 in the up and down and left and right directions, and pulls out the front end portion of the strip sheet 9000 in the arc-shaped T-section cavity 41400, so that the curled and contracted strip sheet 9000 expands radially, breaks away from the supporting arc surface 41100, and tightly adheres to the inner wall of the hose 20000. When the second pulling hook 42240 is in the second pulling and expanding position P10 and the first pulling hook 42130 is in the first pulling and expanding position P8, the concave overlapping tenon 9400 of the strip sheet 9000 pulled by the second pulling hook 42240 and the convex overlapping tenon 9300 pulled by the first pulling hook 42130 can correctly realize the tenon overlap, and the strip sheet 9000 can be reliably attached to the inner wall of the hose 20000 in the form of an annular liner with head and tail overlaps.

[0209] The first pulling mechanism 42100 is manipulated so that the first pulling hook 42130, driven by the first movable body 42120, moves from the first pulling and expanding circle position P8 in the up-down and left-right directions to the first pulling and expanding circle unhooking position P9 in the up-down and left-right directions, at which the first pulling hook 42130 is disengaged from the first pulling process hole 9100. The second pulling mechanism 42200 is manipulated so that the second pulling hook 42240, driven by the third movable body 42230, moves from the second pulling locking hole 9220 to the second pulling through hole 9210 in the front-back direction (i.e., the axial direction of the main axis 0001), at which the second pulling hook 42240 is disengaged from the second pulling through hole 9210. After being separated from their respective pulling process holes, the first pulling hook 42130 and the second pulling hook 42240 respectively move in the radial direction toward the main axis centerline 0001, i.e., they are radially retracted and reset to meet the requirement that the maximum outer envelope diameter K of the liner covering device 40000 is smaller than the minimum inner wall envelope diameter N of the inner wall of the hose 20000.

[0210] Since other components of the device according to the embodiment of the present invention are known to those skilled in the art, they will not be described in detail here.

[0211] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
