Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, specifically a novel tire spraying device. Background Technology

[0002] Tire spraying is a technology used in tire production, primarily to improve air permeability during vulcanization, prevent tires from sticking to molds, enhance product appearance, and extend mold life. The spraying process can be performed on the inside or outside of the tire, and the specific spraying agent used depends on the tire type and manufacturing process.

[0003] Internal coating refers to spraying a special coating onto the inner surface of the tire. This is done to prevent the tire from sticking to the bladder during vulcanization, and also to facilitate air venting, reduce air bubbles, and thus improve tire quality. External coating, on the other hand, is sprayed onto the outer surface of the tire. Its main purpose is to increase the flowability of the rubber compound on the outer surface of the green tire during vulcanization, preventing insufficient rubber formation.

[0004] During the tire painting process, the tire needs to be fixed. Traditional fixing methods usually extend to the inside of the tire, which makes it inconvenient to paint inside the tire and easily leads to uneven painting. Therefore, a new type of tire painting device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel tire spraying device with advantages such as high flexibility and uniform spraying. It solves the problem that the fixed method of traditional tire spraying devices makes it inconvenient to spray inside the tire and easily leads to uneven spraying.

[0006] To achieve the aforementioned goals of good flexibility and uniform spraying, this utility model provides the following technical solution: a novel tire spraying device, comprising a base plate, a spraying machine, and a drive box, wherein a fixing component is provided on the side of the drive box, a drive component is provided inside the drive box, and a tire is sprayed and positioned outside the fixing component.

[0007] Furthermore, the fixing assembly includes a drive rod movably connected to the side of the drive box, a threaded cylinder movably connected to the outside of the drive rod, a clamping frame fixedly installed on the outside of the threaded cylinder, several fixed seats disposed on the side of the drive rod, an adjusting rod movably connected to the side of the fixed seats, several hydraulic telescopic rods fixedly installed on the outside of the fixed seats, a locking seat fixedly installed on the top of the hydraulic telescopic rod, and an adjusting plate fixedly installed on the side of the adjusting rod.

[0008] Furthermore, an inner spray frame is inserted and fixed to the top of the base plate, and an inner spray pipe is provided on the side of the inner spray frame. An outer spray frame is fixedly installed on the top of the drive box, and an arc-shaped nozzle is provided at the bottom of the outer spray frame. Both the inner and outer spray frames are provided with material supply pipes and spraying machine discharge pipes at their tops.

[0009] Furthermore, a stabilizing seat is provided on the side wall of the drive box, and the drive rod passes through the stabilizing seat laterally and is rotatably connected to the stabilizing seat. The surface of the drive rod located on the outside of the stabilizing seat is provided with threaded teeth.

[0010] Furthermore, the threaded cylinder has a threaded through hole inside, the drive rod passes through the threaded through hole laterally and is rotatably connected to the threaded cylinder through the threaded teeth, and the clamping frame has an L-shaped structure and an annular fixing pad is provided on the side.

[0011] Furthermore, the fixed seat includes a positioning seat and a movable seat, the side of the positioning seat and the drive rod are fixedly installed, and the interior of the positioning seat has a threaded through hole.

[0012] One end of the adjusting rod is embedded in the threaded hole and is rotatably connected to the positioning seat via a thread. The adjusting rod passes laterally through the movable seat and is fixedly installed with the movable seat.

[0013] Furthermore, the top side of the card slot is provided with a card slot for defining the sprayed tire, and the side of the adjustment plate is provided with an adjustment handle that is rotatably connected.

[0014] Furthermore, the drive assembly includes a drive motor fixedly mounted on the inner side wall of the drive housing, a transmission gear fixedly mounted on the side of the output shaft of the drive motor, and a driven gear fixedly mounted on the side of the drive rod.

[0015] Furthermore, the tooth grooves on the outer side of the transmission gear and the tooth grooves on the outer side of the driven gear mesh with each other, and the transmission gear and the driven gear are connected by tooth groove transmission.

[0016] Compared with the prior art, this utility model provides a novel tire spraying device, which has the following features:

[0017] Beneficial effects:

[0018] 1. This novel tire spraying device, by passing the inner ring of the tire to be sprayed through the outer side of the clamping seat, allows the inner diameter of the tire to be sprayed to rest on the clamping groove on the surface of the clamping seat. The clamping frame is pushed to rotate, and the rotation of the clamping frame causes the threaded cylinder to move outside the threaded teeth on the outer side of the drive rod, thereby driving the clamping frame to push the annular fixing pad close to the tire to be sprayed. The hydraulic telescopic rod is activated, and the extension of the hydraulic telescopic rod pushes the clamping seat to be evenly supported inside the tire to be sprayed. The annular fixing pad and the clamping seat clamp the inner and outer sides of the tire to be sprayed on one side, respectively. The spraying machine is started to spray the inside of the tire to be sprayed through the inner spray pipe.

[0019] 2. This novel tire coating device rotates by turning the adjustment handle, which in turn rotates the adjustment disc. The rotation of the adjustment disc causes the adjustment rod to rotate, and the adjustment rod rotates in the threaded hole of the positioning seat, causing the adjustment rod to move laterally. The lateral movement of the adjustment rod causes the movable seat to move laterally, which in turn causes the hydraulic telescopic rod and the locking seat to move laterally inside the tire being coated. After the locking seat moves to the bottom of the tire sidewall on the other side, the hydraulic telescopic rod is activated to extend and push the locking seat to lock the tire sidewall on the other side, thus fixing the two sides of the tire. The drive motor is then activated to rotate the tire, and the outer side is coated using an arc-shaped nozzle. This solves the problem that the fixing method of traditional tire coating devices makes it inconvenient to coat the inside of the tire and easily leads to uneven coating.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4In this embodiment, a novel tire spraying device includes a base plate 1, a spraying machine 2, a drive box 3, a fixing component 4 on the side of the drive box 3, a drive component 5 inside the drive box 3, and a spraying tire 6 disposed outside the fixing component 4.

[0027] In this embodiment, an inner spray frame 11 is inserted and fixed to the top of the base plate 1, and an inner spray pipe 12 is provided on the side of the inner spray frame 11. An outer spray frame 13 is fixedly installed on the top of the drive box 3, and an arc-shaped nozzle 14 is provided at the bottom of the outer spray frame 13. The tops of the inner spray frame 11 and the outer spray frame 13 are both provided with material supply pipes and connected to the discharge pipe of the sprayer 2.

[0028] A detachable inner spray frame 11 is installed on the top of the base plate 1, which is convenient for the tire 6 to be initially placed and then installed on the top of the base plate 1. The spraying machine 2 is then started to supply material and spray the inner spray pipe 12 and the arc nozzle 14.

[0029] In this embodiment, the fixing component 4 includes a drive rod 41 movably connected to the side of the drive box 3, a threaded cylinder 42 movably connected to the outside of the drive rod 41, a clamping frame 43 fixedly installed on the outside of the threaded cylinder 42, a plurality of fixing seats 44 disposed on the side of the drive rod 41, an adjusting rod 45 movably connected to the side of the fixing seat 44, a plurality of hydraulic telescopic rods 46 fixedly installed on the outside of the fixing seat 44, a locking seat 47 fixedly installed on the top of the hydraulic telescopic rod 46, and an adjusting plate 48 fixedly installed on the side of the adjusting rod 45.

[0030] A stabilizing seat 31 is provided on the side wall of the drive box 3. The drive rod 41 passes through the stabilizing seat 31 laterally and is rotatably connected to the stabilizing seat 31. The surface of the drive rod 41 located on the outer side of the stabilizing seat 31 is provided with threaded teeth 411. The threaded cylinder 42 is provided with a threaded through hole inside. The drive rod 41 passes through the threaded through hole laterally and is rotatably connected to the threaded cylinder 42 through the threaded teeth 411. The clamping frame 43 has an L-shaped structure and an annular fixing pad 431 is provided on the side.

[0031] A stabilizing seat 31 is provided on the side of the drive box 3 to wrap the drive rod 41, ensuring the stability of the drive rod 41 during rotation. A threaded cylinder 42 with a threaded connection is provided on the outside of the drive rod 41. Rotating the threaded cylinder 42 causes the clamping frame 43 to move the annular fixing pad 431 close to the sprayed tire 6, and then cooperates with the locking seat 47 to fix the sprayed tire 6.

[0032] In this embodiment, the fixed base 44 includes a positioning base 441 and a movable base 442. The side of the positioning base 441 and the drive rod 41 are fixedly installed, and the interior of the positioning base 441 has a threaded through hole. One end of the adjusting rod 45 is embedded in the threaded through hole and is rotatably connected to the positioning base 441 by a thread. The adjusting rod 45 passes laterally through the movable base 442 and is fixedly installed to the movable base 442. The top side of the locking base 47 has a locking slot 471 for limiting the sprayed tire 6, and the side of the adjusting plate 48 is provided with an adjusting handle 481 that is rotatably connected.

[0033] Two different fixing seats 44 are set on the outside of the adjusting rod 45. When the adjusting handle 481 is rotated, the adjusting plate 48 is rotated, which causes the adjusting rod 45 to rotate out of the threaded hole of the positioning seat 441. The movement of the adjusting rod 45 causes the hydraulic telescopic rod 46 and the locking seat 47 to move away from each other, so that the locking seat 47 reaches the bottom of the inner wall of the sprayed tire 6. Then, the extension and retraction of the hydraulic telescopic rod 46 drives the locking seat 47 to fix the sprayed tire 6.

[0034] In this embodiment, the drive assembly 5 includes a drive motor 51 fixedly mounted on the inner wall of the drive housing 3, a transmission gear 52 fixedly mounted on the side of the output shaft of the drive motor 51, and a driven gear 53 fixedly mounted on the side of the drive rod 41. The tooth grooves on the outer side of the transmission gear 52 and the tooth grooves on the outer side of the driven gear 53 mesh with each other, and the transmission gear 52 and the driven gear 53 are connected by tooth groove transmission.

[0035] The drive motor 51 drives the transmission gear 52 to rotate. The meshing of the transmission gear 52 and the driven gear 53 causes the driven gear 53 to rotate, thereby causing the outer painted tire 6 to rotate, achieving the purpose of uniform spraying.

[0036] It should be noted that the drive motor 51 has an automatic lock-up function, and the output shaft can remain stationary and stable when it is not started.

[0037] The working principle of the above embodiments is as follows:

[0038] After the inner ring of the tire 6 is passed through the outer side of the mounting seat 47, the inner diameter of the tire 6 rests on the mounting groove 471 on the surface of the mounting seat 47. The clamping frame 43 is pushed to rotate. The rotation of the clamping frame 43 causes the threaded cylinder 42 to move outside the threaded teeth 411 outside the drive rod 41, thereby driving the clamping frame 43 to push the annular fixing pad 431 closer to the tire 6. The hydraulic telescopic rod 46 is activated. The extension of the hydraulic telescopic rod 46 pushes the mounting seat 47 to be evenly supported inside the tire 6. The annular fixing pad 431 and the mounting seat 47 clamp the inner and outer sides of the tire 6 on one side. The spraying machine 2 is started to spray the inside of the tire 6 through the inner spray pipe 12.

[0039] In addition, by rotating the adjustment handle 481, the adjustment plate 48 is rotated, which in turn drives the adjustment rod 45 to rotate. The adjustment rod 45 rotates in the threaded hole of the positioning seat 441, causing the adjustment rod 45 to move laterally. The lateral movement of the adjustment rod 45 drives the movable seat 442 to move laterally. The lateral movement of the movable seat 442 drives the hydraulic telescopic rod 46 and the locking seat 47 to move laterally inside the sprayed tire 6. After the locking seat 47 moves to the bottom of the other side of the sprayed tire 6, the hydraulic telescopic rod 46 is activated to extend and push the locking seat 47 to lock the other side of the sprayed tire 6, thereby fixing the two sides of the sprayed tire 6. The drive motor 51 is then activated to drive the rotation of the sprayed tire 6, and the arc-shaped nozzle 14 is used to spray the outside. This solves the problem that the fixing method of the traditional tire spraying device makes it inconvenient to spray inside the tire and is prone to uneven spraying.
