Description

A braided tube adhesive coating device Technical Field

[0001] This utility model relates to the field of braided tube production technology, specifically to a braided tube adhesive coating device. Background Technology

[0002] Braided tubing, as a composite tubing material that combines flexibility and structural strength, is widely used in many fields such as hydraulic transmission, engineering machinery, automobile manufacturing, and petrochemicals. One of its core manufacturing processes is rubber coating, which involves wrapping a layer of molten rubber around its steel wire or fiber weave to form an outer rubber layer, achieving functions such as sealing, corrosion prevention, and wear resistance.

[0003] However, in the existing technology, the braided tube passes through the rubber coating equipment, and molten rubber is attached to the outer wall of the tube by high pressure. Since the mandrel used for rubber coating of the braided tube is mostly hollow and has only a single centering and guiding function, a small amount of rubber residue will inevitably remain inside after long-term use. However, the internal structure is compact and the equipment needs to be disassembled one by one to clean the internal space, which is inconvenient for the staff to operate. Summary of the Invention

[0004] The purpose of this invention is to provide a braided tube adhesive application device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a braided tube adhesive coating device, comprising a support platform for fixing the equipment, a plurality of connecting rods fixedly connected to the bottom end of the support platform, an adhesive injection chamber fixedly connected to the bottom end of the connecting rods, a feeding channel for the braided tube to pass through the inner wall of the adhesive injection chamber, and an annular adhesive injection cavity for coating the braided tube with adhesive on the peripheral wall of the feeding channel, a guide mandrel slidably connected in the feeding channel for guiding the braided tube to pass through centrally, and a cleaning mechanism for cleaning the annular adhesive injection cavity provided on the guide mandrel;

[0006] The cleaning mechanism includes an installation cavity formed on the outer wall of the guide core rod, and the installation cavity is provided with a cleaning component for cleaning the cavity wall;

[0007] The guide core rod is also equipped with a recycling component for recycling waste materials.

[0008] Preferably, the cleaning component includes a cleaning scraper blade rotatably connected in an annular array to the inner wall of the mounting cavity. The cleaning scraper blade is used to conform to the annular glue injection cavity to achieve a scraping cleaning operation. A driven gear is concentrically fixedly connected to the shaft end of the cleaning scraper blade.

[0009] An annular gear disk is rotatably connected to the inner wall of the mounting cavity. The annular gear disk meshes with the driven gear. With the setting of several cleaning scrapers, the annular glue injection cavity can be continuously cleaned when the guide mandrel is rotated, and the cleaning operation can be completed without disassembling the equipment.

[0010] Preferably, the cleaning component further includes a rotating tube fixedly connected to the annular toothed disc, the rotating tube being used to drive the rotation of the annular toothed disc, the rotating tube being rotatably connected to the inner wall of the mounting cavity, and an arc-shaped groove being formed on the inner side wall of the rotating tube;

[0011] A pressing tube is slidably connected to the inner wall of the rotating tube. The outer wall of the pressing tube is provided with protrusions that are slidably connected to the arc-shaped groove. Through the setting of the rotating tube, the annular toothed disc can be driven to rotate synchronously. The annular toothed disc drives several cleaning scrapers to rotate through the driven gear, thereby realizing the opening or closing of the cleaning scrapers.

[0012] Preferably, a paddle is fixedly connected to the outer wall of the pressing tube, the paddle extends to the outer wall of the guide rod, and a sliding groove is provided on the outer wall of the guide rod to slide and connect with the paddle, and a locking piece is fixedly connected to the outer wall of one end of the sliding groove.

[0013] Both the locking plate and the lever have threaded holes at their centers for the screw to pass through;

[0014] A return spring is fixedly connected to the top end of the pressing tube, and the top end of the return spring is fixedly connected to the top wall of the mounting cavity. This allows the pressing tube to slide in the rotating tube by pushing the paddle, and the protrusions on the pressing tube to slide in the arc groove, thereby pushing the rotating tube to rotate. The return spring also enables the pressing tube to maintain its upward reset ability, preventing the rotating tube from spinning due to gravity and triggering the unfolding of the cleaning scraper.

[0015] Preferably, a transmission pipe is fixedly connected to the inner wall of the support platform, a positioning cylinder is fixedly connected to the outer wall of the transmission pipe, and a movable cylinder is slidably connected to the outer wall of the positioning cylinder. The inner wall of the movable cylinder is threadedly connected to the outer wall of the guide core. By setting the movable cylinder, the guide core can be connected to the transmission pipe, thereby fixing the position of the guide core.

[0016] Preferably, a strong magnet is fixedly connected to the bottom end of the movable cylinder, and the bottom end of the movable cylinder is in close contact with the lever. The lever is a metal structure. When the movable cylinder is screwed tightly into the outer wall of the guide rod, the strong magnet at the bottom end of the movable cylinder is in close contact with and attracted to the lever. This makes it necessary for the operator to exert more force to push the lever down when accidentally touched, thus reducing the probability of accidental touch.

[0017] Preferably, the recycling component includes a storage box threaded to the bottom end of the guide rod. The storage box has a storage groove inside, which is connected to the mounting cavity. This allows scraped-off waste to fall into the storage groove through the mounting cavity for temporary storage. When removal is required, simply rotate to loosen the movable cylinder, push the guide rod down to expose the storage box, rotate it to remove it, and collect the waste inside for easy reuse.

[0018] Preferably, the outer diameter of the storage box matches the inner diameter of the feeding channel, and an insertion channel for inserting the braided tube is provided at the center of the storage box. The inner wall of the insertion channel and the outer wall of the storage box are both fixedly connected with rubber layers, so that the storage box is tightly attached to the feeding channel through the rubber layers, increasing the sealing performance. The setting of the insertion channel facilitates the passage of the braided tube and does not affect the transmission of the braided tube.

[0019] The beneficial effects of this utility model are as follows:

[0020] In this invention, the expandable cleaning scraper can fit into the annular glue injection cavity to achieve internal cleaning, and the cleaning operation can be completed without disassembling the equipment.

[0021] In this invention, the storage box can be exposed when the guide core is disassembled, making it easier for workers to remove it, remove internal waste, and facilitate the collection and recycling of the waste.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] Please refer to Figures 1 to 8. A braided tube adhesive coating device includes a support platform 1 for fixing the equipment. Several connecting rods 2 are fixedly connected to the bottom end of the support platform 1. An adhesive injection chamber 3 is fixedly connected to the bottom end of the connecting rods 2. A feeding channel 4 for the braided tube to pass through is opened in the inner wall of the adhesive injection chamber 3. An annular adhesive injection cavity 5 is opened in the peripheral wall of the feeding channel 4 for coating the braided tube with adhesive. A guide mandrel 6 is slidably connected in the feeding channel 4 for guiding the braided tube to pass through in the center. A cleaning mechanism 7 for cleaning the annular adhesive injection cavity 5 is provided on the guide mandrel 6.

[0034] The cleaning mechanism 7 includes an installation cavity 71 opened on the outer wall of the guide core rod 6, and a cleaning component 72 for cleaning the cavity wall is provided on the installation cavity 71;

[0035] The guide core 6 is also equipped with a recycling component 73 for recycling waste.

[0036] In this embodiment, as shown in Figures 2 and 3, a transmission pipe 74 is fixedly connected to the inner wall of the support platform 1, a positioning cylinder 75 is fixedly connected to the outer wall of the transmission pipe 74, and a movable cylinder 76 is slidably connected to the outer wall of the positioning cylinder 75. The inner wall of the movable cylinder 76 is threadedly connected to the outer wall of the guide core rod 6. By setting the positioning cylinder 75 and the movable cylinder 76, the guide core rod 6 can be connected to the transmission pipe 74, which facilitates the operation of the guide core rod 6 by the staff.

[0037] In this embodiment, as shown in Figures 2 and 3, a strong magnet 77 is fixedly connected to the bottom end of the movable cylinder 76. The bottom end of the movable cylinder 76 is in contact with the lever 728, and the lever 728 is a metal structure. When the movable cylinder 76 is screwed tightly into the outer wall of the guide core rod 6, the strong magnet 77 at the bottom end of the movable cylinder 76 is in contact with and attracted to the lever 728, so that when the operator accidentally touches it, a greater force is required to push the lever 728 down, thus reducing the probability of accidental touch.

[0038] In this embodiment, as shown in Figures 4, 5 and 6, the cleaning component 72 includes a cleaning scraper 721 that is rotatably connected in an annular array to the inner wall of the mounting cavity 71. The cleaning scraper 721 is used to fit the annular glue injection cavity 5 to achieve a scraping cleaning operation. A driven gear 722 is concentrically fixedly connected to the shaft end of the cleaning scraper 721.

[0039] An annular gear disk 723 is rotatably connected to the inner wall of the mounting cavity 71, and the annular gear disk 723 meshes with the driven gear 722.

[0040] In this embodiment, as shown in Figures 5, 6 and 7, the cleaning component 72 further includes a rotating tube 724 fixedly connected to the annular toothed disk 723. The rotating tube 724 is used to drive the rotation of the annular toothed disk 723. The rotating tube 724 is rotatably connected to the inner wall of the mounting cavity 71. An arc-shaped groove 725 is provided on the inner side wall of the rotating tube 724.

[0041] A pressing tube 726 is slidably connected to the inner wall of the rotating tube 724. The outer wall of the pressing tube 726 is provided with a protrusion 727 that is slidably connected to the arc groove 725. When the lever 728 is manually pushed down, the lever 728 drives the pressing tube 726 to move down. The protrusion 727 on the outer wall of the pressing tube 726 slides in the arc groove 725, pushing the rotating tube 724 to rotate. The rotating tube 724 synchronously drives the annular gear disk 723 to rotate. The annular gear disk 723 drives the driven gear 722 to rotate, causing several cleaning scrapers 721 to rotate and unfold synchronously, so that the cleaning scrapers 721 fit into the annular glue injection cavity 5.

[0042] In this embodiment, as shown in Figures 5, 6 and 7, a paddle 728 is fixedly connected to the outer wall of the pressing tube 726. The paddle 728 extends to the outer wall of the guide rod 6. A sliding groove is provided on the outer wall of the guide rod 6 to slide and connect with the paddle 728. A locking piece 729 is fixedly connected to the outer wall of one end of the sliding groove.

[0043] Both locking piece 729 and lever 728 have threaded holes at their centers for the screw to pass through;

[0044] A return spring is fixedly connected to the top of the pressing tube 726, and the top of the return spring is fixedly connected to the top wall of the mounting cavity 71. When several cleaning scrapers 721 rotate and unfold synchronously, the screw is manually inserted from the locking piece 729 and passes through the lever 728 to limit the position of the lever 728 and prevent the cleaning scrapers 721 from automatically retracting during rotation.

[0045] In this embodiment, as shown in Figure 8, the recycling component 73 includes a storage box 731 threadedly connected to the bottom end of the guide core rod 6. The storage box 731 has a storage groove 732 inside, and the storage groove 732 is connected to the mounting cavity 71. After the cleaning scraper 721 is unfolded, the guide core rod 6 is manually rotated, and the cleaning scraper 721 on it continuously cleans the annular glue injection cavity 5, scraping off the residual waste material until the cleaning is completed. The screw is then manually removed, the paddle 728 is no longer restricted, and the pressing tube 726 is reset upward by the reset spring, driving the rotating tube 724 to rotate in the opposite direction, causing several cleaning scrapers 721 to begin to be collected. During the collection process, the cleaning scraper 721 will push the fallen waste material towards the inside of the mounting cavity 71, so that the waste material falls into the storage groove 732 for temporary storage.

[0046] In this embodiment, as shown in Figure 8, the outer diameter of the storage box 731 matches the inner diameter of the feeding channel 4, and an insertion channel 733 for inserting the braided tube is provided at the center of the storage box 731. The inner wall of the insertion channel 733 and the outer wall of the storage box 731 are both fixedly connected with rubber layers. The rubber layers enable the braided tube to fit snugly against the inner wall of the insertion channel 733, improving the sealing performance and preventing high-pressure molten rubber from leaking and blocking the insertion channel 733.

[0047] The working process of this braided tubing adhesive application device is as follows:

[0048] First, when the equipment is in use, the braided tube passes through the guide mandrel 6 and exits through the insertion channel 733 on the storage box 731, and is gradually transferred to the annular injection cavity 5. The molten rubber is pressed into the annular injection cavity 5 and adheres to the outer wall of the braided tube. The braided tube continuously passes through the annular injection cavity 5 to perform the glue application operation.

[0049] When cleaning is required after processing, the operator only needs to stop the equipment and manually rotate the movable cylinder 76. The movable cylinder 76 rotates on the positioning cylinder 75. Hold the guide core rod 6 with one hand until the movable cylinder 76 is rotated off the guide core rod 6. At this time, the guide core rod 6 is no longer restricted by the movable cylinder 76. Manually push the guide core rod 6 downward into the feeding channel 4 until the cleaning scraper 721 moves to the annular glue injection cavity 5. Manually push the lever 728 downward. The lever 728 drives the pressing tube 726 to move downward. The protrusions 727 on the outer wall of the pressing tube 726 slide in the arc groove 725, pushing the rotating tube 724 to rotate. The rotating tube 724 synchronously drives the annular gear plate 723 to rotate. The annular gear plate 723 drives the driven gear 722 to rotate, causing several cleaning scrapers 721 to rotate and unfold synchronously, so that the cleaning scrapers 721 fit into the annular glue injection cavity 5. At this time, manually insert the screw from the locking piece 729 and through the lever 728 to restrict the position of the lever 728.

[0050] After the cleaning scraper 721 is unfolded, manually rotate the guide rod 6. The cleaning scraper 721 on it will continue to clean the annular glue injection cavity 5, scraping off the residual waste material until the cleaning is completed. Manually remove the screw, and the paddle 728 will no longer be restricted. The pressing tube 726 will be reset upward by the reset spring, driving the rotating tube 724 to rotate in the opposite direction, causing several cleaning scrapers 721 to begin to be stored. During the storage process of the cleaning scraper 721, the fallen waste material will be pushed into the installation cavity 71, so that the waste material will fall into the storage groove 732 for temporary storage.

[0051] Finally, the guide rod 6 is completely removed from the feeding channel 4, and the storage box 731 is rotated to remove it from the guide rod 6. The temporarily stored waste material is then removed and can be reused, completing the entire cleaning process. The staff only needs to operate the guide rod 6 to complete the entire cleaning process without completely disassembling the equipment, thus reducing the difficulty of equipment maintenance.
