All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for filling the glass fiber hose according to the present invention will be described with reference to fig. 1 to 2.
The invention provides a method for pouring a rubber into a glass fiber hose, and in order to facilitate the explanation of the method for pouring the rubber into the glass fiber hose, the embodiment of the invention is described with reference to a rubber pouring device shown in fig. 2. As shown in fig. 1, the method for filling the glass fiber hose includes:
step S1, the first initial glue segment of the hose 1 is laid flat on the conveyor belt.
Step S2, filling a first part of resin between the outer mold and the inner mold of the first initial glue filling section from the end of the first initial glue filling section, and performing glue pushing and thickness setting on the first initial glue filling section through the roller assembly 2.
And step S3, driving the hose 1 to move forward through the conveyor belt until the tail end of the hose 1 moves to the front of the roller assembly 2, so as to finish the first glue filling of the whole section of the hose 1.
Step S4, the second initial glue-pouring section of the hose 1, which has completed the first glue-pouring, is laid on the conveyor belt.
And step S5, pouring a second part of resin between the outer mold and the inner mold of the second initial glue pouring section from the end of the second initial glue pouring section, and performing glue pushing and thickness setting on the second initial glue pouring section through the roller assembly 2.
And step S6, driving the hose 1 to move forward through the conveyor belt until the tail end of the hose 1 moves to the front of the roller assembly 2, so as to finish the second glue filling of the whole hose 1.
Wherein the total amount of the first and second portions of resin is not less than the amount of resin required for the entire length of hose 1.
The embodiment of the invention injects the resin required by the whole section of the hose into the hose 1 by two times. The steps S1-S3 are used for executing first glue filling, and the coming material of the first glue filling hose is a dry material hose. And the steps S4-S6 are used for executing secondary glue filling, and the hose for the secondary glue filling is a wet material hose for finishing the primary glue filling. As shown in fig. 2, the conveyor belt is provided on the table 3 and extends in the longitudinal direction of the hose 1. In the first and second glue pouring processes, the hose 1 is driven by the conveyor belt to move forward, i.e. from the feeding end to the discharging end of the conveyor belt along the direction indicated by the arrow in fig. 2. And the length of the first initial glue filling section and the length of the second initial glue filling section are smaller than or equal to the length of the conveyor belt.
When laying the first initial glue filling section and the second initial glue filling section on the conveyer belt, the end of the hose 1 can be placed on the conveyer belt, and the end of the hose 1 is conveyed to the glue filling station on the workbench 3 through the conveyer belt.
The roller assembly 2 includes at least one roller capable of rotating relative to the conveyor belt, and is used for determining the thickness of the pushed glue in steps S2 and S5 and grinding the routing glue in steps S3 and S6.
When the glue is pushed to be thick, the conveying belt is kept still, the roller of the roller assembly 2 is kept at a set height relative to the conveying belt, and the glue is pushed in the length direction of the conveying belt.
When the wiring is ground to glue, the roller of the roller component 2 is kept still in the length direction of the conveyor belt, the conveyor belt moves to drive the hose 1 to move forwards, and under the action of the roller component 2 and the conveyor belt, the resin is extruded towards the rear of the hose 1.
When glue is poured for the first time, the folded hose 1 is placed at the feeding end of the conveyor belt, and then the first glue pouring section of the hose 1 is laid on the conveyor belt. After the glue filling of the first initial glue filling section is finished, glue is pushed and fixed in thickness at the first initial glue filling section through the roller assembly 2, and the target thickness of the hose 1 after the first glue filling is limited.
When the glue is filled for the second time, the folded hose 1 is placed at the feeding end of the conveyor belt, and then the second initial glue filling section of the hose 1 is paved on the conveyor belt. After the glue filling of the second initial glue filling section is finished, glue is pushed and the thickness is determined at the second initial glue filling section through the roller assembly 2, and the target thickness of the hose 1 after the second glue filling is limited, namely the thickness of the finished hose 1.
According to the method for filling the glass fiber hose provided by the invention, all resin required by the whole section of the hose 1 is filled into the hose 1 in two times, so that a production line can finish first-time filling in a short time, the fluidity of the resin can be maintained in the first-time filling process, the permeability of the glass fiber cloth and the resin on the length of the whole section of the hose 1 is improved, and the filling efficiency can be improved. The resin filled into the hose 1 during the second glue filling can reduce the viscosity of the resin and the glass fiber cloth filled for the first time, promote the resin to permeate the glass fiber cloth, and further improve the permeability of the glass fiber cloth and the resin. The resin amount of the second potting can be adjusted according to the permeation condition of the glass fiber cloth and the resin during the first potting during the second potting, and the full permeation of the resin and the glass fiber cloth is ensured. The embodiment of the invention can realize the glue filling of the hose 1 with longer length under the condition of ensuring that the resin is fully soaked in the glass fiber cloth.
Wherein the hose 1 has a first end and a second end. In the embodiment of the invention, the first initial glue filling section is a glue filling section close to the first end head, and the second initial glue filling section is a glue filling section close to the second end head. The end of the first initial glue filling section is a first end, the tail end of the hose 1 during first glue filling is a second end, the end of the second initial glue filling section is a second end, and the tail end of the hose 1 during second glue filling is the first end.
Under the condition that the length of the hose 1 is long, the fluidity of the resin close to the second end of the hose 1 is reduced during the first glue pouring, and the permeability of the resin and the glass fiber cloth is low. And when the glue is filled for the second time, the second end is used as the end of the second initial glue filling section, and the hose 1 close to the second end is filled with the glue. The resin for the second filling can reduce the viscosity of the resin for the first filling close to the second end head, and the resin is promoted to be fully impregnated with the glass fiber cloth, so that the resin permeability of the whole section of the hose 1 is uniform.
In this embodiment of the present invention, before the step S2, the method further includes: the amount of the first portion of resin and the amount of the second portion of resin are determined according to the pipe diameter of the hose 1, and the amount of the first portion of resin is larger than the amount of the second portion of resin. In the range of the set pipe diameter, the pipe diameter of the hose 1 and the proportion of the first part of resin to the total amount of the twice glue pouring are in inverse proportion. Alternatively, the amount of the first part of the resin accounts for 70% -80% of the amount of the resin required by the whole hose 1, and correspondingly, the amount of the second part of the resin is not less than 20% -30% of the amount of the resin required by the whole hose 1. For example, the amount of the first portion of resin is 70% of the amount of the resin required for the whole hose, and the amount of the second portion of resin is not less than 30% of the amount of the resin required for the whole hose. For another example, the amount of the first portion of resin is 80% of the amount of resin required for the entire length of hose, and the amount of the second portion of resin is not less than 20% of the amount of resin required for the entire length of hose.
In the related art, the inner film of the glass fiber hose is a cylindrical film, the glass fiber cloth and the outer film are both sheet-shaped structures, and the glass fiber cloth is wrapped on the outer side of the inner film in an overlapping or sewing manner. The outer die is wrapped on the outer side of the glass fiber cloth in a welding mode. The lapping or sewing side of the glass fiber cloth and the welding side of the outer die are positioned on the same side of the inner film.
During the glue application process, the hose 1 is flat on a conveyor belt and has a first side and a second side which are arranged in a stacked manner. In the present embodiment, the weld of the hose 1 is located at a first side thereof. In the steps S1 to S3, the first side of the hose 1 is located below the second side. In the steps S4 to S6, the second side of the hose 1 is located below the first side. That is, the weld side of the hose 1 is located at the lower side in the first potting, and the weld side of the hose 1 is located at the upper side in the second potting.
In the embodiment of the present invention, step S2 specifically includes:
step S21, pouring a part of resin in the first part of resin between the lower side outer die and the inner film of the hose 1 from the end of the first glue pouring starting section, and performing glue pushing and thickness setting on the lower layer of resin in the first glue pouring starting section through the roller assembly 2.
Step S22, another part of resin in the first part of resin is poured between the upper side outer die and the inner film of the hose 1 from the end of the first initial glue pouring section, and the upper layer of resin is pushed to the thickness through the roller assembly 2 in the first initial glue pouring section.
Alternatively, in step S1-step S3, the first side of the hose 1 is located below the second side. That is, the lower resin layer in step S21-step S22 of the present embodiment refers to the resin poured into the first side of the hose 1, and the upper resin layer refers to the resin poured into the second side of the hose 1.
In the first glue filling, the lower layer of the hose 1 is first filled with glue in step S21, and the lower layer of resin is pushed to a predetermined thickness by the roller assembly 2, so as to define the thickness of the lower layer of resin. Then, the step S22 is executed to pour the upper layer of the hose 1, and the roller assembly 2 is used to push the upper layer resin to a predetermined thickness, so as to define the thickness of the upper layer resin.
After the thickness of lower floor's resin and upper resin is injectd in proper order, start the conveyer belt and walk the line and grind gluey, push lower floor's resin and upper resin to hose 1 rear simultaneously, until accomplishing the first encapsulating of whole section hose 1.
In this embodiment of the present invention, before the step S2, the method further includes: and determining the resin amount filled between the outer mold and the inner film at the lower side of the hose 1 and the resin amount filled between the outer mold and the inner film at the upper side of the hose 1 during the first glue filling according to the pipe diameter of the hose 1. When the glue is filled for the first time, the resin amount filled between the outer die and the inner die on the lower side of the hose 1 is larger than the resin amount filled between the outer die and the inner die on the upper side of the hose 1. After the lower resin is poured into the first initial glue pouring section, the lower resin can flow back to the upper layer partially due to the fluidity of the resin. The resin volume that this embodiment was filled between hose 1 downside external mold and the interior membrane through setting up when encapsulating for the first time is greater than the resin volume of filling between hose 1 downside external mold and the interior membrane, can improve the permeability of hose 1 lower floor's resin and glass fiber cloth.
Optionally, the weld of the hose 1 is located at said first side. The resin volume that this embodiment irritates into the first lateral part of hose 1 when encapsulating for the first time through setting up is greater than the resin volume of irritating into the 1 second lateral part of hose, is favorable to guaranteeing that the glass fiber cloth in the 1 first lateral part of hose is fully soaked with the resin.
In the embodiment of the present invention, step S5 specifically includes:
and step S51, pouring a part of resin in the second part of resin between the lower side outer die and the inner film of the hose 1 from the end of the second initial glue pouring section, and performing glue pushing and thickness setting on the lower layer of resin in the second initial glue pouring section through the roller assembly 2.
And step S52, pouring another part of resin in the second part of resin between the upper outer die and the inner film of the hose 1 from the end of the second initial glue pouring section, and performing glue pushing and thickness setting on the upper layer of resin in the second initial glue pouring section through the roller assembly 2.
Optionally, in steps S4-S6, the second side of the hose 1 is located below the first side. That is, the lower resin layer in step S51-step S52 of the present embodiment refers to the resin poured into the second side of the hose 1, and the upper resin layer refers to the resin poured into the first side of the hose 1.
In the second glue filling, the lower layer of the hose 1 is first filled with glue in step S51, and the lower layer of resin is pushed to a predetermined thickness by the roller assembly 2, so as to define the thickness of the lower layer of resin. Then, the step S52 is executed to pour the upper layer of the hose 1, and the roller assembly 2 is used to push the upper layer resin to a predetermined thickness, so as to define the thickness of the upper layer resin.
After the thickness of injecing lower floor resin and upper resin in proper order, start the conveyer belt and walk the line and grind gluey, push lower floor resin and upper resin to hose 1 rear simultaneously, until accomplishing the second encapsulating of whole section hose 1 to accomplish the encapsulating of whole section hose 1, form the hose finished product.
In the embodiment of the present invention, in the case that the weld of the hose 1 is located at the first side portion, before the step S2, the method further includes: and determining the resin amount filled between the outer mold and the inner film at the lower side of the hose 1 and the resin amount filled between the outer mold and the inner film at the upper side of the hose 1 during the second glue filling according to the pipe diameter of the hose 1. And during the second glue filling, the resin amount filled between the outer mold and the inner film on the lower side of the hose 1 is smaller than the resin amount filled between the outer mold and the inner film on the upper side of the hose 1. The resin volume that this embodiment was filled between 1 downside external mold of hose and the inner membrance through the setting is less than the resin volume of filling between 1 upside external mold of hose and the inner membrance when encapsulating for the second time, is favorable to guaranteeing that the glass fiber cloth in the first lateral part of hose 1 fully soaks with the resin.
In the embodiment of the present invention, the conveyor belt is disposed on the worktable 3, and the roller assembly 2 includes a first roller 21, a second roller 22, a third roller 23 and a fourth roller 24 which are mounted on the worktable 3. The fourth roller 24, the third roller 23, the second roller 22, and the first roller 21 are arranged in this order along the conveying direction of the conveyor belt, and are movable in both the front-rear direction and the up-down direction of the table 3.
The lower layer resin and the upper layer resin are subjected to sizing to a thickness by the first roller 21, the second roller 22, the third roller 23, and the fourth roller 24 in steps S2 and S5.
In the embodiment of the present invention, the step S21 of performing the glue pushing and thickness determination of the lower layer resin in the first glue filling starting section through the roller assembly 2 includes:
in step S211, before filling a part of the second part of the resin, the fourth roller 24 is moved to the tail end of the first initial glue filling section, and the fourth roller 24 is moved downwards to press the hose 1.
In step S212, after filling a part of the second resin, the third roller 23 is moved down to a first set height to define the thickness of the upper resin. The third roller 23 is moved from the end of the first initial glue section towards the fourth roller 24 to the first position. So that a certain thickness of the lower layer of resin remains in the hose 1 between the first roller 21 and the third roller 23, the remaining lower layer of resin being confined between the third roller 23 and the fourth roller 24. During the subsequent routing of the glue, the lower layer of resin defined between the third roller 23 and the fourth roller 24 is gradually poured into the rear hose 1.
In step S22, the thickness of the upper layer resin is determined by the roller assembly 2 on the first initial glue filling section, which includes:
step S221, moving the second roller 22 downwards to a second set height to define the thickness of the lower resin layer, and moving the second roller 22 from the end of the first initial glue filling section to the third roller 23 to a second position. So that a certain thickness of upper resin remains in the hose 1 between the first roller 21 and the second roller 22, and the remaining upper resin is confined between the second roller 22 and the third roller 23. In the subsequent routing and glue rolling process, the upper resin layer defined between the second roller 22 and the third roller 23 is gradually filled into the rear hose 1.
Step S222, moving the first roller 21 downwards to a third set height to define a target thickness of the hose 1 after the first glue filling. The first roller 21 is moved from the end of the first initial glue section towards the second roller 22 to a third position.
The first set height, the second set height and the third set height are all heights of the corresponding roller relative to the conveying belt. The second set height is larger than or equal to the third set height and is larger than the first set height.
Wherein the second set height may be slightly higher than the third set height, so that a resin slightly thicker than the target thickness of the hose 1 after the first potting may be left between the first roller 21 and the second roller 22 to sufficiently impregnate the fiberglass cloth between the first roller 21 and the second roller 22 with the resin, while ensuring that most of the upper resin is confined between the second roller 22 and the third roller 23. It will be appreciated that a second set height is used to define the overall thickness of the hose 1 after the first pour, and a third set height is used to define the overall thickness of the hose 1 after the first pour again.

During the subsequent routing of the glue, the lower layer of resin defined between the third roller 23 and the fourth roller 24 is gradually poured into the rear hose 1.
In step S52, the glue thickness of the upper layer resin is determined by the roller assembly 2 on the second initial glue filling segment, which includes:
in step S521, the second roller 22 is moved downward to a fifth set height to define the thickness of the lower resin layer, and the second roller 22 is moved from the end of the second initial glue filling section to the third roller 23 to a second position. So that a certain thickness of upper resin remains in the hose 1 between the first roller 21 and the second roller 22, and the remaining upper resin is confined between the second roller 22 and the third roller 23. In the subsequent course of running and grinding the glue, the upper resin layer confined between the second roller 22 and the third roller 23 is gradually poured into the rear hose 1.
In step S522, the first roller 21 is moved downward to a sixth set height to define a target thickness of the hose 1 after the second glue filling. The first roller 21 is moved from the end of the second initial glue segment to the second roller 22 to a third position.
The fourth set height, the fifth set height and the sixth set height are the heights of the corresponding rollers relative to the conveyor belt, and the fifth set height is larger than or equal to the sixth set height and is larger than the fourth set height.
