Description

Technical Field

[0001] The utility model specifically relates to a dust collection pipeline connecting device. Background Art

[0002] Rock wool board has the characteristics of light weight, low thermal conductivity, heat absorption, and non-combustibility. It is a new type of thermal insulation, flame retardant, and sound absorption material. At present, when cutting rock wool boards, in order to prevent the dust and debris generated during the cutting process from affecting the working environment and the health of operators, it is usually connected to the cutting equipment with an external dust collection device.

[0003] In the prior art, the vacuum hose on the vacuum device is mostly directly connected to the dust inlet pipe on the cutting device, which cannot limit the bending of the vacuum hose and the dust inlet pipe when the cutting device moves back and forth linearly, so that the vacuum hose is easily damaged due to excessive bending angle, shortening the service life of the vacuum hose and increasing the cost of equipment use. Therefore, in view of the above technical problems, a vacuum pipe connection device is proposed. Utility Model Content

[0008] The beneficial effects of the above-mentioned dust collection pipe connection device are:

[0009] When the cutting machine moves reciprocatingly linearly, the cutting machine drives the dust inlet pipe and the connecting pipe to move.

The limit ring stops rotating and limits the connection between the dust suction hose and the dust inlet pipe from continuing to bend, and causes the dust suction hose to bend at the connection between the dust suction hose and the limit ring. By dispersing the bending angles at different positions, the phenomenon of damage caused by excessive bending angles of the dust suction hose is avoided, the service life of the dust suction hose is extended, and the equipment use cost is reduced.

By providing a reset spring, when the cutting machine moves to make the limit ring rotate in the opposite direction relative to the moving direction of the cutting machine, the limit block rotates to squeeze the reset spring, and when the gas cutting machine moves in the opposite direction, the reaction force of the reset spring can make the limit block rotate in the opposite direction, and the limit block can drive the limit ring to rotate in the opposite direction through the connecting rod when it rotates in the opposite direction, so as to facilitate the reset of the limit ring after rotation, and the reset of the limit ring is convenient.

[0011] In one embodiment, the stop ring includes a first half ring and a second half ring; two groups of connecting rods are arranged on the circumferential side of the first half ring, one end of the second half ring is hinged to one end of the first half ring, and the other end of the second half ring is connected to the other end of the first half ring through an open latch.

[0031] In the above embodiment, by setting a reset spring 303, when the cutting machine moves to make the limit ring 305 rotate in the opposite direction relative to the moving direction of the cutting machine, the limit block 302 rotates to squeeze the reset spring 303. When the gas cutting machine moves in the opposite direction, the reaction force of the reset spring 303 can make the limit block 302 rotate in the opposite direction. The limit block 302 rotates in the opposite direction and can drive the limit ring 305 to rotate in the opposite direction through the connecting rod 304, thereby facilitating the reset of the limit ring 305 after rotation, and the reset of the limit ring 305 is convenient.

By replacing the gasket rings 306 of different thicknesses, the limiting ring 305 can be easily mounted on the vacuum hoses 20 of different sizes, thereby improving the practicality of the device.

[0036] See also Figure 2 , Figure 4 In one embodiment, the limit assembly further includes a telescopic assembly 40, which includes a telescopic rod 401 and a driving member. Two groups of telescopic rods 401 are relatively fixedly connected to the periphery of the limit ring 305. Two groups of connecting rods 304 are slidably sleeved on the two groups of telescopic rods 401. The driving member is rotatably arranged on the periphery of the limit ring 305 and connected to the connecting rod 304. Rotating the driving member can drive the telescopic rod 401 to slide. Specifically, the driving member includes a screw rod 402; the screw rod 402 is arranged parallel to the telescopic rod 401, and the top end is rotatably arranged on the periphery of the limit ring 305, and the bottom end is threadedly connected to the connecting rod 304.

[0037] In the above embodiment, the screw rod 402 can be driven to move by rotating the screw rod 402 and the connecting rod 304 threadedly matched, and the movement of the screw rod 402 can drive the telescopic rod 401 to move and extend the matching length of the connecting rod 304 and the telescopic rod 401. The screw 402 can be driven to move in the opposite direction by reversing the screw rod 402 and the connecting rod 304 threadedly matched, and the reverse movement of the screw 402 can drive the telescopic rod 401 to move in the opposite direction to shorten the matching length of the connecting rod 304 and the telescopic rod 401. By adjusting the matching length of the connecting rod 304 and the telescopic rod 401, the position of the limit ring 305 can be adjusted, so that the position of the limit ring 305 sleeved on the dust suction hose 20 can be adjusted according to needs, so as to change the position of the dust suction hose 20 and the bending position of the limit ring 305, and further improve the service life of the dust suction hose 20.

[0038] The specific implementation of the above-mentioned dust collection pipe connecting device is as follows:

[0039] When the cutting machine moves reciprocatingly linearly, the cutting machine drives the dust inlet pipe 10 and the connecting pipe 301 to move. The movement of the connecting pipe 301 and the misalignment of the dust suction hose 20 can cause the dust suction hose 20 to bend at the connection between the dust suction hose 20 and the connecting pipe 301. At the same time, the limiting ring 305 rotates in the opposite direction of the moving direction of the cutting machine. The rotation of the limiting ring 305 can drive the two groups of limiting blocks 302 to rotate. When the two groups of limiting blocks 302 rotate and collide with one end of the two groups of arc-shaped limiting grooves 3011, the limiting ring 305 stops rotating. The limiting ring 305 stops rotating, which can limit the dust suction hose 20 from continuing to bend at the connection between the dust inlet pipe 10, and cause the dust suction hose 20 to bend at the connection between the dust suction hose 20 and the limiting ring 305. By dispersing the bending angles at different positions, the phenomenon of damage caused by excessive bending angles at the connection between the dust suction hose 20 and the dust inlet pipe 10 is avoided, the service life of the dust suction hose 20 is extended, and the equipment use cost is reduced.

[0040] At the same time, the screw rod 402 can be driven to move by rotating the screw rod 402 and the threaded engagement with the connecting rod 304. The movement of the screw rod 402 can drive the telescopic rod 401 to move to extend or shorten the matching length of the connecting rod 304 and the telescopic rod 401. When the matching length of the connecting rod 304 and the telescopic rod 401 is adjusted appropriately, stop rotating the screw rod 402 to fix the matching length of the connecting rod 304 and the telescopic rod 401. By adjusting the matching length of the connecting rod 304 and the telescopic rod 401, the position of the limit ring 305 can be adjusted, so that the position of the limit ring 305 on the dust suction hose 20 can be adjusted according to needs, so as to change the position of the bending part of the dust suction hose 20 and the limit ring 305, thereby further improving the service life of the dust suction hose 20.
