Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gluing, in particular to a gluing machine. BACKGROUND

[0002] At present, the gluing of pipe fittings is generally carried out by mechanical automation. During gluing, the pipe fitting is placed on the gluing station, then the rotating drive member drives the steel brush to rotate, so that the steel brush adheres to the glue and approaches the pipe fitting, then the rotating drive member is disconnected from the steel brush, and finally the steel brush is driven to rotate around the pipe fitting by another drive member to coat the surface of the pipe fitting with glue. In the above process, after the rotating drive member is disconnected from the steel brush, in order to ensure that the steel brush can tightly adhere to the pipe fitting, a spring is generally connected to the steel brush to apply a pre-tightening force to the steel brush, so that the steel brush tightly adheres to the pipe fitting. The above structure has the following problems, i.e. after the rotating drive member is disconnected from the steel brush, the steel brush will directly hit the pipe fitting under the action of the spring force, so that the pipe fitting has a probability of deviating from the original position and the glue on the steel brush splashes, which finally affects the gluing of the pipe fitting.

[0038] As Figures 1-9As shown, the glue coating machine provided by the embodiment of the application comprises a base 1; the base 1 is provided with a clamping assembly, a glue coating assembly and a glue storage pool 4. The clamping assembly comprises two clamping jaws 21 and a clamping cylinder 22 for driving the two clamping jaws 21 to open and close. The glue coating assembly comprises a rotating disc 31, a first rotary driving member 32, a positioning core 33, a glue brushing assembly, an elastic member, a second rotary driving member and a buffer clutch assembly. The first rotary driving member 32 is connected with the center of the rotating disc 31 for driving the rotating disc 31 to rotate; the positioning core 33 is rotatably arranged at the center of the rotating disc 31, and the positioning core 33 is arranged on the two sides of the rotating disc 31 in the thickness direction and opposite to the clamping space between the two clamping jaws 21; the glue brushing assembly comprises a rotary shaft 341, a mounting seat 342 and a brush head 343, the rotary shaft 341 is rotatably arranged at the position deviating from the center of the rotating disc 31, the two ends of the rotary shaft 341 extend out of the rotating disc 31, the mounting seat 342 and the brush head 343 are fixedly connected at the two ends of the rotary shaft 341 respectively, and the brush head 343 is located on the same side of the rotating disc 31 as the positioning core 33; the elastic member is used for providing the brush head 343 with a rotating force for approaching the positioning core 33; the second rotary driving member can be connected with or separated from the rotary shaft 341, and when the second rotary driving member is connected with the rotary shaft 341, the second rotary driving member can drive the rotary shaft 341 to rotate; the buffer clutch assembly comprises a clutch driving member 361, a buffer wheel 362 and a buffer plate 363, the buffer wheel 362 is arranged on the mounting seat 342, the buffer plate 363 is provided with an arc surface 3631, and the clutch driving member 361 can drive the buffer plate 363 to move to a buffer position, so that the distance between the buffer wheel 362 and the arc surface 3631 gradually decreases during the rotating process of the brush head 343 approaching the positioning core 33; the glue storage pool 4 is arranged directly below the brush head 343.

[0039] In use, one end of a pipe to be coated with glue is sleeved on the positioning core 33. Then the other end of the pipe is clamped by the two clamping jaws 21 of the clamping assembly, so as to fix the pipe to be coated with glue. Specifically, the two clamping jaws 21 of the clamping assembly are in an open state at the beginning, and when clamping is needed, the clamping cylinder drives the two clamping jaws 21 to approach each other, so as to realize the closing of the two clamping jaws 21 and further clamp the pipe. Then, the clutch driving member 361 drives the buffer plate 363 to move to the buffer position. Then, the second rotary driving member is connected with the rotary shaft 341 and drives the rotary shaft 341 to rotate. Specifically, when the rotary shaft 341 rotates, the brush head 343 arranged at one end of the rotary shaft 341 also rotates. Specifically, referring to Figures 4-5 and Figure 8, the brush head 343 will rotate from the downward direction to the upward direction, in this process, the brush head 343 can absorb the glue in the glue pool 4 below it. Then, the second rotary drive is separated from the rotating shaft 341, at this time the brush head 343 will rotate to the pipe under the action of the elastic force of the elastic member, it should be noted that, since the distance between the buffer wheel 362 and the arc surface 3631 gradually decreases during the rotation of the brush head 343 to the positioning core 33, the friction between the buffer wheel 362 and the arc surface 3631 will gradually increase during the rotation of the brush head 343 to the pipe, and the relative speed of the two will gradually slow down, so that the brush head 343 will not directly hit the pipe as in the prior art, that is, through the cooperation of the buffer wheel 362 and the buffer plate 363, the buffer of the brush head 343 is realized, the deviation of the pipe and the splashing of the glue are avoided, and the reliability of the glue coating is ensured. Finally, the clutch drive 361 drives the buffer plate 363 away from the buffer position, and the first rotary drive 32 drives the rotating disc 31 to rotate, at this time the brush head 343 rotates around the pipe in the state of being close to the pipe to coat the glue.

[0040] As a preferred embodiment, the base 1 is further provided with a first housing 5 surrounding the glue coating assembly. Through the protection of the first housing 5, the service life of the glue coating machine of the present application can be prolonged.

[0041] Preferably, an arc-shaped enclosing cover 6 is arranged outside the rotating disc 31 and connected to the glue pool 4. By arranging the arc-shaped enclosing cover 6, the glue on the brush head 343 can be prevented from being thrown out due to centrifugal force during the rotation of the rotating disc 31, thereby protecting the operator.

[0042] Preferably, a partition plate 41 is arranged in the glue pool 4, and the partition plate 41 is arranged in the middle of the glue pool 4 to divide the glue pool 4 into a central storage area 411 and an outer recovery area 412. In this way, the brush head 343 can absorb relatively clean glue when in use. That is, after the brush head 343 absorbs glue in the central storage area 411, it will coat the glue with the rotation of the rotating disc 31, and during this process, part of the glue will drip from the brush head 343. Since the rotating disc 31 rotates by a certain angle, the dripping glue on the brush head 343 will fall into the outer recovery area 412. That is, the dripping glue is separated from the original glue in the present application, which ensures the reliability of the glue coating.

[0043] Preferably, the base 1 is further provided with a second housing 7 surrounding the clamping assembly, the glue pool 4 and the arc-shaped enclosing cover 6, and the second housing 7 is provided with an observation window 71 opposite to the rotating disc 31. Similarly, the second housing 7 can also play a protective role. The observation window 71 can facilitate the user to observe the glue coating state in real time.

[0044] Preferably, the elastic member is a spring, the rotating disc 31 is provided with a first spring post 311, the mounting seat 342 is provided with a second spring post 3421, and the two ends of the spring are connected with the first spring post 311 and the second spring post 3421 respectively. That is, through the action of the spring, the brush head 343 has a rotating trend to approach the positioning core 33.

[0045] Preferably, the second rotating driving member includes a parallel cylinder 351 and a rotating cylinder 352, the parallel cylinder 351 is connected with the rotating cylinder 352, the parallel cylinder 351 is used to drive the rotating cylinder 352 to approach or move away from the rotating shaft 341 along the axial direction of the rotating shaft 341, when the rotating cylinder 352 is in the position close to the rotating shaft 341, the output shaft of the rotating cylinder 352 is adapted to be connected with the rotating shaft 341, when the rotating cylinder 352 is in the position away from the rotating shaft 341, the output shaft of the rotating cylinder 352 is adapted to be separated from the rotating shaft 341. Specifically, the output shaft of the rotating cylinder 352 is coaxially arranged with the rotating shaft 341, and the output shaft of the rotating cylinder 352 is further provided with a connecting seat, the connecting seat is provided with a connecting hole, and the hole diameter of the connecting hole gradually decreases along the direction away from the rotating shaft 341, when the parallel cylinder 351 drives the rotating cylinder 352 to approach the rotating shaft 341 along the axial direction of the rotating shaft 341, since the hole diameter of the connecting hole gradually decreases along the direction away from the rotating shaft 341, the connecting seat will eventually be connected with the rotating shaft 341 to transmit the rotating torque.

[0046] Preferably, the rotating shaft 341 is rotatably connected with the rotating disc 31 through a bearing. By arranging the bearing, the rotation between the rotating shaft 341 and the rotating disc 31 can be smoother, so that the elastic member only needs a smaller elastic force to make the brush head 343 closely contact with the pipe.

[0047] Preferably, the positioning core 33 is conical, and the smaller end of the positioning core 33 is away from the rotating disc 31. By arranging the positioning core 33 as a conical shape, the pipe can be conveniently sleeved, that is, the conical shape has a guiding effect, so that the pipe is easier to be sleeved.

[0048] Preferably, the clutch driving member 361 includes a clutch cylinder 3611, a swing rod 3612 and a connecting shaft 3613, the first end of the clutch cylinder 3611 is hinged with an external fixed seat, the second end of the clutch cylinder 3611 is hinged with the first end of the swing rod 3612, the second end of the swing rod 3612 is connected with the first end of the connecting shaft 3613, and the first end of the connecting shaft 3613 is connected with the buffer plate 363. Referring to Figures 6-8When the clutch cylinder 3611 is elongated, the second end of the clutch cylinder 3611 will drive the swing lever 3612 to swing around the second end of the swing lever 3612, and the second end of the swing lever 3612 is connected with the connecting shaft 3613, and the connecting shaft 3613 is connected with the buffer plate 363, so that the elongation of the clutch cylinder 3611 can drive the buffer plate 363 to rotate, so that the buffer plate 363 moves to the buffer position.
