[0028] Please refer to Figures 1-4 The utility model discloses a hot melt welding machine, including:

[0029] The body 1 is provided with two clamping mechanisms 2 capable of being detachably connected with two pipes respectively, one of the clamping mechanisms 2 is fixedly connected with the body 1, and the other clamping mechanism 2 is slidably connected with the body 1;

[0030] The first pushing assembly 3 is arranged on the body 1 and is used for pushing the corresponding clamping mechanism 2 to move towards or away from the other clamping mechanism 2 along the pipe axis direction;

[0031] The heating assembly 4 is movably arranged on the body 1 and can be moved to the position between the two pipes and heat the adjacent end of the two pipes;

[0032] The two cutter assemblies 5 are used for cutting the crimping edges on the two pipes respectively;

[0033] The two adjusting mechanisms 6 are arranged on the opposite sides of the two clamping mechanisms 2 respectively, can rotate around the pipe axis direction, and can push the two cutter assemblies 5 to move towards or away from the crimping edges of the pipes;

[0034] The appearance inspection probe 7 is arranged on one of the adjusting mechanisms 6 and can move synchronously with the corresponding cutter assembly 5 and detect the crimping edges of the pipes.

[0035] The utility model discloses a hot melt welding machine which comprises a body 1, two clamping mechanisms 2 capable of being detachably connected with two pipes respectively, one of the clamping mechanisms 2 is fixedly connected with the body 1, and the other clamping mechanism 2 is slidably connected with the body 1, a first pushing assembly 3 arranged on the body 1 and used for pushing the corresponding clamping mechanism 2 to move towards or away from the other clamping mechanism 2 along the pipe axis direction, a heating assembly 4 movably arranged on the body 1 and capable of being moved to the position between the two pipes and heating the adjacent end of the two pipes, two cutter assemblies 5 used for cutting the crimping edges on the two pipes respectively, and two adjusting mechanisms 6 arranged on the opposite sides of the two clamping mechanisms 2 respectively, can rotate around the pipe axis direction, and can push the two cutter assemblies 5 to move towards or away from the crimping edges of the pipes.

[0036] In an embodiment, the clamping mechanism 2 is composed of an upper clamp 21 and a lower clamp 22, the upper clamp 21 and the lower clamp 22 are detachably connected, and are used for clamping and fixing the pipe located between the upper clamp 21 and the lower clamp 22;

[0037] The adjusting mechanism 6 comprises a sliding block 61, the upper clamp 21 and the lower clamp 22 are respectively provided with a sliding groove for the sliding block 61 to slide, the sliding block 61 is provided with a driving component 62 located in the sliding groove, the output shaft of the driving component 62 is provided with a gear 63 driven to rotate by the driving component 62, the upper clamp 21 and the lower clamp 22 are respectively provided with an annular tooth groove meshing with the gear 63, and the second pushing component 64 for pushing the corresponding cutter assembly 5 to move close to or away from the pipe edge is arranged on the side of the sliding block 61 away from the driving component 62.

[0038] In this way, the clamping mechanism 2 can not only clamp and fix the pipe, but also serve as the moving track of the adjusting mechanism 6, so that the gear 63 can rotate along the pipe axis when the driving component 62 drives the gear 63 to rotate, and the cutter assembly 5 inserted into the pipe edge can be completely cut off the external welding edge during the rotation.

[0039] It should be noted that the driving component 62 has a self-locking structure, which can lock the rotating shaft after stopping operation, so that the gear 63 can be maintained at the set position, and the first pushing component 3 and the second pushing component 64 can adopt the hydraulic telescopic component, the pneumatic telescopic component and the electric telescopic component in the prior art, and the driving component 62, the first pushing component 3 and the second pushing component 64 all belong to the common knowledge in the field, so the specific structure and working principle will not be described in detail.

[0040] In an embodiment, the cutter assembly 5 comprises a cutter 51 arranged on the corresponding second pushing component 64 and a limiting block 52 arranged on the corresponding second pushing component 64 and used for preventing the two cutters 51 from colliding when they move close to each other.

[0041] In this way, after the two cutters 51 are respectively inserted into the pipe edge and moved to the position, the two limiting blocks 52 abut against each other, preventing the two cutters 51 from further moving close to each other, so as to avoid the damage caused by the collision between the two cutters 51.

[0042] In an embodiment, the appearance inspection probe 7 is arranged on the second pushing component 64, the distance between the appearance inspection probe 7 and the corresponding sliding block 61 is greater than the distance between the cutter 51 and the corresponding sliding block 61, and the moving area of the appearance inspection probe 7 does not overlap with the moving area of the other cutter assembly 5.

[0043] In this way, when the appearance inspection probe 7 moves to the pipe edge area, the corresponding cutter 51 will not contact the edge, so that the detection operation of the appearance inspection probe 7 will not be affected by the cutter 51, and when the two cutters 51 move close to each other, the appearance inspection probe 7 will not collide with the other cutter assembly 5 because the moving area of the appearance inspection probe 7 does not overlap with the moving area of the other cutter assembly 5.

[0044] In an embodiment, the appearance inspection probe 7 comprises an infrared ranging probe for emitting a light beam to the measured pipe and a camera module for visual recognition.

[0045] In this way, by moving the appearance inspection probe 7, three rays perpendicular to the pipe are emitted in sequence, the distance between each two rays is L1 and L2 respectively, then the appearance inspection probe is moved by a certain radian in the circumferential direction of the pipe, and then three rays perpendicular to the pipe are emitted in sequence after being fixed, until the whole circumference is completed.

[0046] (1) When L1=L2, it indicates that the crimping symmetry of the hot melt welding joint is qualified.

[0047] (2) When |L1-L2|≤10% of the pipe wall thickness, it indicates that the symmetry of the hot melt welding joint is qualified.

[0048] It should be noted that the radian of each movement of the appearance inspection probe 7 can be adjusted as needed.

[0049] In another embodiment, the appearance inspection probe 7 comprises an ultrasonic probe and a camera module, and the appearance inspection probe 7 and the cutter 51 can be moved towards and away from the side of the pipe, so that the appearance inspection probe 7 can evaluate the quality of the welding joint by ultrasonic detection.

[0050] In this way, the area of the welding joint that is contaminated and has bubbles can be detected, and the quality of the hot melt butt joint is further confirmed on the basis of appearance detection of the welding joint quality, which meets the requirements of the welding joint of the plastic pipe in daily production.

[0051] It should be noted that if the embodiments of the utility model have directionality indications (such as up, down, left, right, front, back, etc.), the directionality indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directionality indications also change accordingly.
