[0025] Please refer to Figures 1 to 6 The utility model provides a roller rubber coating machine for sheathing a rubber hose 1 into a roller 2, comprising a frame 3, a glue feeding mechanism 4, a clamping rod mechanism 5, a rod supporting mechanism 6 and an inflation device 7; the glue feeding mechanism 4 and the clamping rod mechanism 5 are respectively arranged at both ends of the frame 3; the rod supporting mechanism 6 is arranged on the frame 3 and is located between the glue feeding mechanism 4 and the clamping rod mechanism 5; the clamping rod mechanism 5 is used to clamp one end of the roller 2, and the other end of the roller 2 can be movably placed on the rod supporting mechanism 6, and the clamping rod 5 can be clamped. The rod mechanism 5 reserves space for movement, so that one end of the roller rod 2 can still move up and down slightly after being clamped, so as to facilitate the insertion of the hose 1; the glue feeding mechanism 4 includes a driving mechanism 41 and a driving wheel 42, and the driving mechanism 41 is transmission-connected to the driving wheel 42, and the driving wheel 42 drives the hose 1 to move toward the rod supporting mechanism 6; the inflation device 7 is connected to one end of the hose 1, and the other end of the hose 1 is connected to the glue feeding device, and the inflation device 7 is used to fill air into the inner cavity of the hose 1.

[0026] In the embodiment of the present invention, a roller 2 rubber coating machine is used to assist in inserting the rubber hose 1 into the roller 2. Compared to traditional manual rubber coating methods, this embodiment of the roller 2 rubber coating machine significantly simplifies the rubber coating process, requiring only minimal manual assistance to quickly complete the rubber coating of the roller 2. Specifically, the clamping mechanism 5 in this embodiment is used to clamp one end of the roller 2, ensuring stability during the rubber coating process and preventing any shaking that may affect the rubber coating process. The supporting mechanism 6 is used to support the other end of the roller 2. The roller 2 is movable on the supporting mechanism 6 to facilitate the insertion of the rubber hose 1. In order to facilitate the rubber sleeve to enter the roller rod 2, this embodiment is provided with an inflation device 7 and a glue feeding mechanism 4, wherein the function of the inflation device 7 is to inject high-pressure air into the rubber hose 1 to make the rubber hose 1 expand, thereby increasing the gap between the rubber hose 1 and the roller rod 2, and facilitating the insertion of the rubber hose 1; the function of the glue feeding mechanism 4 is to drive the rubber hose 1 forward so that the rubber hose 1 actively enters the roller rod 2, without the need to manually press the rubber hose 1 into the roller rod 2 as in the traditional way, which greatly reduces the manpower burden.

[0027] The working process of this utility model is as follows:

[0028] The inflation device 7 is started to inject air into the hose 1, and the glue feeding mechanism 4 drives the hose 1 forward and contacts the roller 2; when the hose 1 is inserted into the roller 2, the air outlet of the hose 1 becomes smaller, and the air inside the hose 1 acts on the tube body of the hose 1, causing the tube body to expand, thereby increasing the gap between the hose 1 and the roller 2; the glue feeding mechanism 4 continues to drive the hose 1 forward, and then manually grasps the outer side of the hose 1 and rotates the hose 1 left and right to guide the hose 1 forward. Due to the existence of the gap, the hose 1 can be quickly put onto the roller 2 under the drive of the inspection mechanism.

[0029] Preferably, the driving wheel 42 includes two rubber feeding wheel groups, which have the same structure and are symmetrically arranged with a front-to-back spacing; the rubber feeding wheel groups include an upper roller 421 and a lower roller 422, and the upper roller 421 rotates in opposite directions to the lower roller 422, and both are respectively connected to the driving mechanism 41. Through the above structural design, the two rubber feeding wheel groups act on the rubber hose 1 at the same time, avoiding the situation where one group of rubber feeding wheel groups is prone to slipping. Specifically, the upper roller 421 and the lower roller 422 clamp the rubber hose 1 at the same time, and then the upper roller 421 and the lower roller 422 rotate at the same time under the drive of the driving mechanism 41. When rotating, the friction force is used to bring the rubber hose 1 out, so that the rubber hose 1 moves toward the roller 2.

[0030] Preferably, the upper roller 421 and the lower roller 422 have the same structure, both having a spindle-like structure with a narrow center and thick ends. In this embodiment, to better clamp the hose 1, the upper roller 421 and the lower roller 422 adopt a spindle-like structure. When the upper roller 421 and the lower roller 422 are connected, the hose 1 passes through the gap between them. The thin center and thick ends structure can effectively clamp the hose 1 and drive it forward.

[0031] Preferably, the frame 3 is further provided with two limiting roller mechanisms, which are arranged in a one-to-one manner with the two rubber feeding wheel groups; the limiting roller mechanism includes an upper cross bar 423, a lower cross bar 424, a left roller 425 and a right roller 426; the upper cross bar 423 and the lower cross bar are arranged parallel to each other; one end of the left roller 425 is rotatably connected to the upper cross bar 423, and the other end is rotatably connected to the lower cross bar 424; one end of the right roller 426 is rotatably connected to the upper cross bar 423, and the other end is rotatably connected to the lower cross bar 424; the left roller 425 and the right roller 426 are arranged parallel to each other. In this embodiment,

[0032] Because the spindle-shaped upper roller 421 and lower roller 422 may shift when driving the hose 1, causing it to become stuck between the upper and lower rollers 421, 422 and unable to move. To this end, this embodiment provides a limiting roller mechanism to control the deviation of the hose 1. Specifically, the left roller 425 and the right roller 426 are respectively positioned on the left and right sides of the hose 1 conveying path. During conveyance, the left roller 425 acts on the left side of the hose 1, while the right roller 426 acts on the right side of the hose 1. This ensures that the hose 1, which enters between the upper and lower rollers 421, 422, maintains a stable travel without shifting.

[0033] Preferably, the driving mechanism 41 includes a motor 411, a reducer 412, a driving pulley 413, a synchronous belt, a driven pulley, and a transmission wheel group; the reducer 412 is arranged at the top of the frame 3, and the motor 411 is connected to the reducer 412 in transmission; the driving pulley 413, the driven pulley and the transmission wheel group are respectively arranged on the side of the frame 3; the output end of the reducer 412 is connected to the driving pulley 413, the driving pulley 413 and the driven pulley are connected through the synchronous belt, the driven pulley is connected to the transmission wheel group, and the transmission wheel group is respectively connected to the two rubber feeding wheel groups. Through the above structural design, the motor 411 outputs power through the reducer 412, and then drives the active pulley 413 to rotate. The active pulley 413 drives the driven pulley to rotate through the synchronous belt. The driven pulley transmits power to the transmission wheel group. The transmission wheel group transmits power to the two rubber feeding wheel groups by setting multiple gears or belts, thereby driving the operation of the two rubber feeding wheel groups.

[0034] Preferably, the rod-supporting mechanism 6 includes a limiting roller set 61 and a supporting rubber roller 62. The limiting roller set 61 is used to limit the position of the roller 2 and the rubber sleeve, and the supporting rubber roller 62 is located between the limiting roller set 61 and the rubber feeding mechanism 4. The limiting roller set 61 includes a left rubber roller 611 and a right rubber roller 612, which are symmetrically arranged on the frame 3. During installation, the roller 2 passes between the left rubber roller 611 and the right rubber roller 612, and the bottom surface of the roller 2 contacts the top surface of the front rubber roller. In this embodiment, the rod-supporting mechanism 6 is provided with the limiting roller set 61 and the supporting rubber roller 62. The limiting roller set 61 functions to prevent the roller 2 from deviating. When the rubber hose 1 is inserted into the roller 2, it can limit the position of the roller 2 after the rubber sleeve is applied, thereby preventing the roller 2 from falling when the rubber sleeve is manually rotated. Specifically, the limiting roller assembly 61 employs a paired structure consisting of a left rubber roller 611 and a right rubber roller 612. These two rollers act on either side of the hose 1, maintaining the hose 1 and roller 2 in proper position and preventing them from falling out. The supporting rubber roller 62 is rotatably mounted on the frame 3. When the hose 1 is inserted into the roller 2, the rotatable supporting rubber roller 62 facilitates insertion and reduces friction on the surface of the hose 1 during the insertion process.

[0035] Preferably, the clamping mechanism 5 includes a clamping base and a movable clamping plate. Each of the clamping base and the movable clamping plate is provided with an arcuate groove that mates with the roller 2. The movable clamping plate is bolted to the clamping base. In this embodiment, the removable movable clamping plate allows the roller 2 to be quickly secured. The removable clamping plate then secures the roller 2 with bolts, ensuring that one end of the roller 2 remains relatively fixed to the frame 3 for rubber laminating operations.

[0036] Preferably, the inflation device 7 includes an air compressor 71 and an automatic inflation valve 72. The air outlet of the air compressor 71 is connected to the automatic inflation valve 72, and the automatic inflation valve 72 is connected to the end of the hose 1. In this embodiment, by using the automatic inflation valve 72, the inflation process inside the hose 1 can be more effectively controlled, avoiding overinflation that may cause the hose 1 to rupture, and also avoiding underinflation that may cause a small gap and affect the sleeve effect.

[0037] Preferably, an electrical control box is provided at the bottom of the frame 3, connected to the drive mechanism 41. A control switch 8 is provided on the front of the frame 3, connected to the electrical control box. Because the coupling process between the hose 1 and the roller 2 requires manual assistance, in order to better control the advancement of the hose 1, this embodiment provides a control switch 8 on the front of the frame 3. Manual operation of the control switch 8 activates the drive mechanism 41, driving the hose 1 forward. When a pause is required, simply stopping the control switch 8 quickly shuts it down.

[0038] Preferably, the frame 3 is provided with a lifting mechanism, the top of which is provided with a support block, the top surface of which is provided with an arc-shaped inner groove; a lifting switch is provided on the side of the frame 3, and the lifting switch is connected to the lifting mechanism. The lifting mechanism is provided to drive the support block upward, so that the support block contacts the bottom of the roller 2 and lifts the roller 2. In contrast, the clamping mechanism 5 in this embodiment has reserved space for movement, allowing the roller 2 to rotate slightly up and down with the clamping mechanism 5 as the center. When the roller 2 is lifted, the end of the roller 2 near the supporting mechanism 6 rises, making it easier for the hose 1 to enter the roller 2 without being pressed against the supporting mechanism 6 by the roller 2 and difficult to insert. When the hose 1 reaches the position of the lifting mechanism, the roller 2 is lowered by the lifting switch. At this time, since most of the hose 1 is already inserted into the roller 2, the roller 2 can be inserted smoothly even after it is lowered.

[0039] Compared with the existing technology, the present invention has the following beneficial effects: The present invention uses an inflation device to inject air into the rubber hose, maintaining a gap between the rubber hose and the roller. The rubber feeding mechanism then drives the rubber hose forward, making manual rubber hose insertion more labor-efficient. A clamping mechanism is also provided to clamp the roller, preventing it from moving during rubber application, significantly improving the efficiency of roller rubber application. After rubber application is completed, the inflation device is deactivated, ensuring a tight fit between the rubber hose and the roller surface, smoothing the rubber sleeve surface and achieving a good rubber application effect. The present invention has a reasonable design and a simple structure. While improving rubber application efficiency and reducing labor costs, it also enhances rubber application quality and is easy to promote and use.

Many modifications and variations will be apparent to those skilled in the art.
