[0040] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0041] In the description of the present invention, it should be clarified that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, but are not necessarily used to describe a specific order or sequence; the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, and do not mean that the referred device or element must have a specific direction or position, and therefore cannot be understood as a limitation on the present invention.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] When the liquid inlet pipe bending sleeve integrated machine of air-conditioning parts assembly production equipment produces the liquid inlet pipe sleeve, the sleeve ring assembly will occasionally have an abnormal clamping phenomenon. When the clamping ring appears, it will cause the liquid inlet pipe to fail to be put on the ring and the material channel will be blocked. If the clamping ring is not processed for a period of time, the processing equipment will eventually have a clamping ring shutdown alarm, which greatly affects the production efficiency and production quality.

[0044] Based on the above phenomenon, the cause of the abnormal liquid inlet pipe production process was analyzed by observing on-site production. There are two types of retaining rings: one is the lower ring position retaining ring, and the other is the ring 10 that is stuck in the material channel (first material channel 21) inside the lower ring plate (first substrate 2) of the sleeve. Generally, the ring 10 is stuck in the middle and bottom of the lower ring plate (first substrate 2) of the sleeve (first material channel 21).

[0045] Example 1

[0046] like Figure 1-11As shown, an embodiment of the present invention provides an anti-blocking structure for a bending sleeve integrated machine, the bending sleeve integrated machine includes a collar assembly, the collar assembly includes a bottom plate 1, a first substrate 2 and a first partition 3, the first substrate 2 is arranged on the bottom plate 1, the first partition 3 is arranged on one side of the first substrate 2, the side wall of the first substrate 2 facing the first partition 3 is configured with a first material channel 21, the anti-blocking structure includes a rebound anti-blocking telescopic part 41, the rebound anti-blocking telescopic part 41 is arranged on the first substrate 2, and the first telescopic part 411 of the rebound anti-blocking telescopic part 41 can be abutted against the first partition 3.

[0047] In this embodiment, the anti-blocking structure is used for the bending sleeve integrated machine, which includes a collar assembly, which includes a bottom plate 1, a first substrate 2 and a first partition 3. The first substrate 2 is arranged on the bottom plate 1, and the first partition 3 is arranged on one side of the first substrate 2. The side wall of the first substrate 2 facing the first partition 3 is configured with a first material channel 21. Since the anti-blocking structure of this embodiment includes a rebound anti-blocking telescopic member 41, the rebound anti-blocking telescopic member 41 is arranged on the first substrate 2, and the first telescopic portion 411 of the rebound anti-blocking telescopic member 41 can abut against the first partition 3, when the ring is lowered, the first telescopic portion 411 is pushed forward to abut against the first partition 3. After the ring is lowered, the first telescopic portion 411 immediately performs at least one retreat and forward movement. The retreat and forward movement generate vibrations, which greatly eliminates the possibility of the clamping ring.

[0048] It can be seen that the anti-blocking structure of the present application solves the problem that the ring assembly of the liquid inlet pipe bending sleeve integrated machine of the air-conditioning parts assembly production equipment will occasionally have an abnormal clamping ring phenomenon when producing the liquid inlet pipe ring. The phenomenon of the open ring welding ring not falling will no longer occur frequently, and the liquid inlet pipe will not be able to be put on the ring and the clamping ring will not stop due to the clamping ring, which greatly improves the stability and production quality of the liquid inlet pipe bending sleeve integrated machine equipment.

[0049] In some embodiments, the anti-blocking structure further includes an elastic member 42 , and the elastic member 42 is clamped between the first substrate 2 and the first partition plate 3 .

[0050] In this embodiment, by clamping the elastic member 42 between the first substrate 2 and the first partition plate 3, when the first telescopic portion 411 retracts after the lower ring is completed, the gap between the first substrate 2 and the first partition plate 3 is increased, thereby making the first material channel 21 larger, which is convenient for the passage of the ring 10. The phenomenon of open-loop welding ring not falling will no longer occur frequently, and the liquid inlet pipe will not be able to be put on the ring and the clamping ring will not stop due to the clamping ring. This greatly improves the stability and production quality of the liquid inlet pipe bending sleeve all-in-one equipment.

[0051] In some embodiments, the position of the first partition 3 facing the first material channel 21 is a hollow structure, which facilitates the passage of the ring 10. The phenomenon of open-loop welding rings not falling will no longer occur frequently, and the liquid inlet pipe will not be able to be put on the ring and the clamping ring will not stop due to the clamping ring. This greatly improves the stability and production quality of the liquid inlet pipe bending and sleeve integrated machine equipment.

[0052] In some embodiments, the anti-blocking structure also includes a first side plate 43 arranged on the side of the first substrate 2 facing the first partition 3 and located on at least one side of the first partition 3, the rebound anti-blocking telescopic member 41 is arranged on the side of the first side plate 43 away from the first substrate 2, and the first telescopic part 411 faces the first partition 3.

[0053] In this embodiment, the rebound anti-blocking telescopic component 41 is fixed to the side of the first substrate 2 facing the first partition 3 through the first side plate 43, so that the rebound anti-blocking telescopic component 41 and the first partition 3 are spaced apart, and the first telescopic portion 411 can extend toward the first partition 3 through one side of the first side plate 43.

[0054] In some embodiments, the collar assembly further includes a second substrate 5 and a second partition 6, wherein the second substrate 5 is disposed on the top of the first substrate 2, and a second material channel 51 communicating with the first material channel 21 is disposed on one side of the second substrate 5 facing the second partition 6.

[0055] In some embodiments, the sleeve ring assembly also includes a discharge telescopic member 44, a first dividing rod 45 and a second dividing rod 46, the discharge telescopic member 44 is arranged on the side of the second substrate 5 away from the second partition 6, the first dividing rod 45 and the second dividing rod 46 are both connected to the second telescopic portion 441 of the discharge telescopic member 44; when the second telescopic portion 441 is extended and retracted, the first dividing rod 45 and the second dividing rod 46 can be driven to alternately extend into the second material channel 51, so that the second material channel 51 between the first dividing rod 45 and the second dividing rod 46 can accommodate a ring 10.

[0056] In this embodiment, the mutual cooperation between the discharging telescopic member 44, the first material dividing rod 45 and the second material dividing rod 46 can enable the second material channel 51 to place the next ring 10 at a time, thereby preventing the second material channel 51 from being stuck due to too many rings being placed, thereby improving the stability and production quality of the liquid inlet pipe bending sleeve integrated machine equipment.

[0057] In some embodiments, the first dividing rod 45 and the second dividing rod 46 are respectively located on both sides of the second substrate 5, and in the feeding direction of the second material channel 51, the first dividing rod 45 and the second dividing rod 46 are arranged in sequence, and the first dividing rod 45 and the second dividing rod 46 are parallel to the axis of the second telescopic portion 441. The structure of this embodiment can make the first dividing rod 45 and the second dividing rod 46 alternately extend into the second material channel 51 when the second telescopic portion 441 is telescoped, so as to achieve that the second material channel 51 located between the first dividing rod 45 and the second dividing rod 46 can accommodate a ring 10, thereby preventing too many lower rings from causing the second material channel 51 to be stuck, thereby improving the stability and production quality of the liquid inlet pipe bending sleeve all-in-one machine equipment.

[0058] In some embodiments, when the first dividing rod 45 extends into the second material channel 51 , the first dividing rod 45 is inserted into a ring 10 adjacent to the ring 10 located between the first dividing rod 45 and the second dividing rod 46 .

[0059] In some embodiments, the anti-blocking structure also includes a first connecting plate 47 and a second connecting plate 48, and the first connecting plate 47 and the second connecting plate 48 are respectively located on both sides of the second substrate 5, and the first connecting plate 47 and the second connecting plate 48 are both vertically connected to the second telescopic portion 441, and the first dividing rod 45 is vertically inserted on the first connecting plate 47, and the second dividing rod 46 is vertically inserted on the second connecting plate 48.

[0060] In this embodiment, the first dividing rod 45 is fixed to the second telescopic part 441 by the first connecting plate 47, and the second dividing rod 46 is fixed to the second telescopic part 441 by the second connecting plate 48, so that the first dividing rod 45 and the second dividing rod 46 are alternately extended into the second material channel 51, so that the second material channel 51 located between the first dividing rod 45 and the second dividing rod 46 can accommodate a ring 10, thereby preventing the second material channel 51 from being stuck due to too many lower rings, thereby improving the stability and production quality of the liquid inlet pipe bending sleeve all-in-one equipment.

[0061] There is another reason for the generation of the snap ring, which is mainly that the discharge telescopic member 44 is loosened by the fixing screw, resulting in the discharge telescopic member 44 being unable to drive the movement of the material distribution rod and unable to realize the lower ring function. Specifically, a through hole is opened on the mounting plate 49, and the fixing screw is passed through the through hole to lock on the discharge telescopic member 44. The discharge telescopic member 44 moves very frequently, and the discharge telescopic member 44 is made of aluminum alloy, which is relatively soft and easy to deform. Therefore, the discharge telescopic member 44 is very easy to loosen and needs to be re-tightened in a week. In addition, the fixing screw is easy to slip, and the discharge telescopic member 44 can only be scrapped after slipping.

[0062] In some embodiments, the anti-blocking structure also includes a mounting plate 49 and a locking component 50, the mounting plate 49 is connected to the second substrate 5, the discharge telescopic component 44 has a through hole 442, the mounting plate 49 has a locking hole 491, and the locking component 50 is locked with the locking hole 491 via the through hole 442.

[0063] In this embodiment, a through hole 441 is opened in the discharge telescopic part 44, a locking hole 491 is set on the mounting plate 49, and the mounting plate 49 is made of steel. The locking part 50 is locked with the locking hole 491 via the through hole 442. Therefore, the discharge telescopic part 44 can be prevented from loosening, and the locking part 50 is not easy to slip, thereby reducing the scrap rate of the discharge telescopic part 44.

[0064] The anti-blocking structure of the present invention can improve the stability of equipment from 80% to 98%, improve the qualified quality of produced pipes from 80% to 99%, and basically eliminate equipment shutdown and unqualified products caused by sleeve rings and clamps.
