Description

Technical Field

[0001] This utility model relates to the technical field of braided tube vulcanization equipment, specifically to a continuous braided tube adhesive coating and vulcanization device. Background Technology

[0002] Braided tubing, a high-strength pipe formed by combining steel wire and other materials with a rubber layer, is widely used in industrial transmission, medical equipment, hydraulic devices, and other fields. It is an indispensable piece of equipment in modern industry. Generally, during the production of braided tubing, the inner rubber tube is braided first, and then glue is applied. Through the bonding of the braided layer and the inner and outer rubber layers, the strength of the pipe can be greatly increased. Finally, the rubber layer is treated with vulcanization equipment to increase its strength.

[0003] During the continuous processing of braided tubing, excess adhesive will remain on the outer wall of the braided tubing after gluing, requiring sizing and trimming of the outer diameter. However, traditional cutting devices have a fixed and unadjustable cutting radius, which cannot adapt to the processing needs of different pipe diameters, resulting in low equipment versatility. Utility Model Content

[0004] The purpose of this invention is to provide a continuous braided tube coating and vulcanization 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 continuous braided pipe coating and vulcanization device, comprising a processing chamber for supporting components, a closed pressure impregnation device body fixedly connected to the inner wall of the processing chamber, the closed pressure impregnation device body being used to coat the outer wall of the braided pipe with adhesive, and a cutting component for trimming the pipe being provided in the inner wall of the processing chamber.

[0006] The cutting assembly includes a processing cylinder rotatably connected to one side of the enclosed pressure impregnation device body. The inner wall of the processing cylinder is provided with cutting parts for alternating cutting, and the processing cylinder is also provided with cleaning parts for cleaning the cutting parts to improve the cutting effect.

[0007] Preferably, the cutting component includes two symmetrically arranged positioning rings, and a rotating disk for controlling the cutting radius is fixedly connected to the inner wall of the positioning rings. A plurality of arc-shaped grooves are arranged in a ring array on one side of the rotating disk.

[0008] Several arc-shaped grooves are slidably connected to the inner walls of several arc-shaped grooves, and scrapers with equal spacing are fixedly connected to the inner walls of several arc-shaped plates. Several arc-shaped plates achieve relative movement through the extrusion of the arc-shaped grooves, thereby controlling the relative position of several scrapers and adjusting the operating radius of the scrapers.

[0009] Preferably, two annular bearing disks are symmetrically fixedly connected to the inner wall of the processing cylinder, and straight grooves are arranged in annular array on both annular bearing disks. The straight grooves are slidably connected to one end of the arc plate. When the arc plate is squeezed and moved by the groove wall of the arc plate, the arc plate can only move in a straight line due to the restriction of the straight groove, thus restricting several arc plates to always keep the same center.

[0010] Preferably, the cutting component further includes an electric push rod fixed in the inner wall of the processing cylinder, the pushing end of the electric push rod is fixedly connected to a support plate, and the front end of the support plate is fixedly connected to a reduction motor for driving the rotary disk to rotate.

[0011] The geared motor has a bidirectional output shaft structure, and drive gears are fixedly connected to both main shafts of the geared motor. A ring gear meshes on the outer tooth groove of the drive gear, and the side wall of the ring gear is fixedly connected to the rotating disk.

[0012] Both ends of the support plate are fixedly connected to trigger rods. By changing the left and right positions of the reduction motor, the usage state of different scrapers can be controlled to facilitate the switching of scrapers.

[0013] Preferably, the inner wall of the positioning ring has an installation cavity, and a locking piece is slidably connected to the inner wall of the installation cavity;

[0014] The front end of the locking piece is protruding, and a sloping groove is provided on the side wall of the locking piece. The sloping groove is inclined to the lower right, and the sloping groove and the trigger rod are located in the same horizontal direction.

[0015] The top of the locking plate is fixedly connected to a telescopic spring rod, and the other end of the telescopic spring rod is fixedly connected to the inner wall of the mounting cavity. When the position of the reduction motor is changed, the rotating disk at the corresponding position can be unlocked simultaneously, so as to control the operating radius of the corresponding scraper through the reduction motor, while the other set of scrapers is locked, which does not affect the normal use of the device.

[0016] Preferably, the outer wall of the rotating disk has a plurality of insertion interfaces arranged in a ring array, and the inner diameter of the insertion interface matches the outer diameter of the front end protrusion of the locking piece. Through the insertion interface and the locking piece protrusion, the rotating disk can maintain a self-locking state in the initial state, avoiding changes in the position of the scraper due to the rotation of the rotating disk.

[0017] Preferably, the cleaning component includes a ring array of vents on the support plate, and several vents correspond one-to-one with several scrapers, and the exhaust direction of the vents is inclined.

[0018] An air pump is fixedly connected to the inner wall of the processing cylinder, and the two ends of the air pump are respectively connected to an air inlet pipe and an air outlet pipe. The air outlet pipe is connected to the air vent, and the air inlet pipe extends to the outer wall of the processing cylinder. With the air vent, air can be blown onto the outer wall of the scraper when the scraper is unfolded and retracted, and the adhered objects are blown off by the high-speed airflow.

[0019] Preferably, an annular pulley is fixedly connected to the side wall of the processing cylinder, and a transmission belt is sleeved on the outer wall of the annular pulley. A servo motor is sleeved on one end of the transmission belt, and the servo motor is fixedly connected to the inner wall of the processing chamber.

[0020] A vertical vulcanization crosslinking tube is installed below the processing cylinder. The servo motor drives the processing cylinder to rotate through the transmission belt and the annular pulley, so that the scraper rotates synchronously with the processing cylinder, which can clean and trim the rubber layer of the braided tube that it passes through.

[0021] The beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up two symmetrically arranged arc-shaped plates and scrapers, the annular spacing of several scrapers can be adjusted as needed to adapt to adhesive layers of different thicknesses, while the scrapers trim the adhesive layer.

[0023] In this invention, by setting up two sets of scrapers, different scrapers can be switched and the retracted scrapers can be cleaned to avoid excessive rubber buildup on the scrapers after long-term use, which would affect the cutting effect.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] 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.

[0034] Please see Figures 1 to 7 A continuous braided pipe coating and vulcanization device includes a processing chamber 1 for supporting components, a closed pressure impregnation device body 2 fixedly connected to the inner wall of the processing chamber 1, the closed pressure impregnation device body 2 for coating the outer wall of the braided pipe with adhesive, and a cutting component 3 for trimming the pipe is provided in the inner wall of the processing chamber 1.

[0035] The cutting assembly 3 includes a processing cylinder 4 rotatably connected to one side of the enclosed pressure impregnation device body 2. The inner wall of the processing cylinder 4 is provided with a cutting element 31 for alternating cutting, and the processing cylinder 4 is also provided with a cleaning element 32 for cleaning the cutting element 31 to improve the cutting effect.

[0036] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, an annular pulley 33 is fixedly connected to the side wall of the processing cylinder 4, and a transmission belt is sleeved on the outer wall of the annular pulley 33. A servo motor is sleeved on one end of the transmission belt, and the servo motor is fixedly connected to the inner wall of the processing chamber 1.

[0037] A vertical vulcanization crosslinking tube 34 is installed below the processing cylinder 4. The processed braided tube is sent into the vertical vulcanization crosslinking tube 34 to perform vulcanization operation on the rubber layer.

[0038] In this embodiment, as Figure 4 and Figure 5As shown, the cutting component 31 includes two symmetrically arranged positioning rings 311. A rotating disk 312 for controlling the cutting radius is fixedly connected to the inner wall of the positioning rings 311. Several arc-shaped grooves 313 are arranged in a ring array on one side of the rotating disk 312.

[0039] Arc plates 314 are slidably connected to the inner walls of several arc grooves 313, and scrapers 315 are fixedly connected to the inner walls of several arc plates 314 at equal intervals. The arc plates 314 achieve relative movement through the compression of the arc grooves 313, thereby controlling the relative position of several scrapers 315 and adjusting the operating radius of the scrapers 315.

[0040] In this embodiment, as Figure 4 and Figure 5 As shown, two annular bearing disks 316 are symmetrically fixedly connected to the inner wall of the processing cylinder 4, and straight grooves 317 are arranged in annular array on both annular bearing disks 316. The straight grooves 317 are slidably connected to one end of the arc plate 314. When the arc plate 314 is squeezed and moved by the groove wall of the arc groove 313, the arc plate 314 can only move in a straight line due to the restriction of the straight grooves 317, thus restricting several arc plates 314 to always keep the same center.

[0041] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the cutting component 31 also includes an electric push rod 318 fixed in the inner wall of the processing cylinder 4. The pushing end of the electric push rod 318 is fixedly connected to a support plate 319, and the front end of the support plate 319 is fixedly connected to a reduction motor 3120 for driving the rotary disk 312 to rotate.

[0042] The geared motor 3120 has a bidirectional output shaft structure, and drive gears 3121 are fixedly connected to both main shafts of the geared motor 3120. A ring gear 3122 meshes on the outer tooth groove of the drive gear 3121, and the side wall of the ring gear 3122 is fixedly connected to the rotating disk 312.

[0043] Both ends of the support plate 319 are fixedly connected to trigger rods 3123. By changing the left and right positions of the reduction motor 3120, the usage state of different scrapers 315 can be controlled to facilitate the switching of scrapers 315.

[0044] In this embodiment, as Figure 4 and Figure 6 As shown, a mounting cavity 3124 is provided in the inner wall of the positioning ring 311, and a locking piece 3125 is slidably connected in the inner wall of the mounting cavity 3124.

[0045] The front end of the locking piece 3125 is protruding, and a sloping groove 3126 is provided on the side wall of the locking piece 3125. The sloping groove 3126 is inclined to the lower right, and the sloping groove 3126 and the trigger rod 3123 are located in the same horizontal direction.

[0046] The top of the locking piece 3125 is fixedly connected to a telescopic spring rod, and the other end of the telescopic spring rod is fixedly connected to the inner wall of the mounting cavity 3124. When the position of the reduction motor 3120 is changed, the corresponding rotating disk 312 can be unlocked simultaneously, so that the operating radius of the corresponding scraper 315 can be controlled by the reduction motor 3120, while the other set of scrapers 315 is locked, which does not affect the normal use of the device.

[0047] In this embodiment, as Figure 4 and Figure 6 As shown, a number of insertion interfaces 3127 are arranged in a ring array on the outer wall of the rotating disk 312, and the inner diameter of the insertion interface 3127 matches the outer diameter of the front end protrusion of the locking piece 3125. Through the insertion of the insertion interface 3127 and the protrusion of the locking piece 3125, the rotating disk 312 can maintain a self-locking state in the initial state, and avoid the change of the position of the scraper 315 due to the rotation of the rotating disk 312.

[0048] In this embodiment, as Figure 4 and Figure 7 As shown, the cleaning component 32 includes a ring array of vents 321 on the support plate 316, and several vents 321 correspond one-to-one with several scrapers 315. The exhaust direction of the vents 321 is inclined.

[0049] An air pump 322 is fixedly connected to the inner wall of the processing cylinder 4, and the two ends of the air pump 322 are respectively connected to an air inlet pipe and an air outlet pipe. The air outlet pipe is connected to the air vent 321, and the air inlet pipe extends to the outer wall of the processing cylinder 4. With the setting of the air vent 321, when the scraper 315 is unfolded and retracted, air can be blown towards the outer wall of the scraper 315, and the adhesive objects are blown off by the high-speed airflow.

[0050] The computer software involved in the hardware carriers such as the enclosed pressure impregnation device body, geared motor, electric push rod, air pump, and servo motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the utility model application.

[0051] Therefore, the "closed pressure impregnation device body", "gear motor", "electric push rod", "air pump", "servo motor" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0052] The continuous braided tube coating and vulcanization device operates as follows:

[0053] First, the braided tube is passed through the closed pressure impregnation device body 2. The rubber is adhered to the braided tube by high pressure inside. The braided tube with the outer rubber layer passes through it. At this time, the annular pulley 33 on the side wall of the processing cylinder 4 is connected to the servo motor through the transmission belt, so that the processing cylinder 4 keeps rotating. The scraper 315 inside rotates with the processing cylinder 4. When the braided tube passes the scraper 315, the scraper 315 will trim the outer rubber layer to the corresponding size. The braided tube continues to be conveyed forward and trimmed until it is discharged from the processing cylinder 4 and sent into the vertical vulcanization crosslinking tube 34 for vulcanization treatment of the rubber layer.

[0054] Then, after the equipment has been running for a period of time, the electric push rod 318 drives the support plate 319 to move to the left. The reduction motor 3120 on the support plate 319 moves synchronously to the left until the drive gear 3121 on the left side of the reduction motor 3120 contacts the ring gear 3122 on the left rotating disk 312. At this point, the trigger rod 3123 on the left side of the support plate 319 inserts into the support disk 316 on the left side of the processing cylinder 4 and presses against the inclined groove 3126. Figure 6 As shown, when the trigger rod 3123 is pressed against the inclined groove 3126, it indirectly pushes the locking piece 3125 to move upward. The protruding end of the locking piece 3125 separates from the insertion interface 3127 on the rotating disk 312. At this time, the rotating disk 312 is unlocked, and the reduction motor 3120 drives the drive gear 3121 to rotate. The drive gear 3121 drives the rotating disk 312 to rotate through the ring gear 3122. When the arc groove 313 of the rotating disk 312 rotates synchronously, it will press against the side wall of the arc plate 314, causing the arc plate 314 to slide relative to the arc groove 313. Since the other side of the arc groove 313 is slidably connected to the straight groove 317, several arc plates 314 drive the scraper 315 to move radially until it reaches the set position, thus completing the change of the cutting radius.

[0055] Next, when the position of the lower scraper 315 changes, the electric push rod 318 is activated again to push the support plate 319 to move to the right. Similarly, the drive gear 3121 on the right side of the reduction motor 3120 is connected to the ring gear 3122 on the rightmost rotating disk 312, and is inserted into the corresponding locking plate 3125's insertion interface 3127 through the trigger rod 3123 on the right side of the support plate 319. The locking plate 3125 moves upward, unlocking the rotating disk 312. At this time, the reduction motor 3120 drives the drive gear 3121 to rotate in the opposite direction. The drive gear 3121 drives the rotating disk 312 to rotate in the opposite direction to the previous rotating disk 312 through the ring gear 3122. This causes the several arc plates 314 on the rotating disk 312 to separate, and the several scrapers 315 on this side gradually move away from the braided tube.

[0056] Then, when several scrapers 315 are away from the braided tube, a high-speed airflow can be sprayed out from the air port 321 by the air pump 322. The high-speed airflow impacts the surface of the scraper 315, blowing off the residue on the scraper 315 for cleaning, so as to avoid long-term adhesion and affect the cutting effect.

[0057] The specific models of the enclosed pressure impregnation device body 2, geared motor 3120, electric push rod 318, air pump 322, and servo motor mentioned above are: GYJ-800 high-pressure impregnation machine, TECO5IK90RGU dual-axis motor, TENC-80 electric push rod, RB-077 air pump, and MHMJ082G1U servo motor.
