DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The core of the utility model is to provide a bowl cleaning device, which can be quickly reset after being hit, with a short maintenance time and no impact on the production process.

[0034] The bowl cleaning device provided by the utility model comprises a cleaning mechanism 1, a fixed base 2 and a rotating mechanism 3. Please refer to Figure 1 , Figure 2 , Figure 6 .

[0035] The cleaning mechanism 1 is used for docking with the long shroud to perform cleaning operations. The specific structure of the cleaning mechanism 1 is not limited and can be flexibly changed in combination with the applicable long shroud.

[0036] One end of the fixed base 2 is fixed to the ground to obtain support. To ensure the reliability of the support, other components, such as connecting columns, support plates, etc., can be used to ensure reliable and effective fixation between one end of the fixed base 2 and the ground.

[0037] The other end of the fixed base 2 is rotatably connected to a rotating mechanism 3, which is fixedly connected to the cleaning mechanism 1, that is, the rotating mechanism 3 and the cleaning mechanism 1 act as a community, and the community can rotate relative to the fixed base 2 when the cleaning mechanism 1 is hit.

[0038] The rotating mechanism 3 includes a support plate 31, a safety screw 32 and a spring pin assembly 33, wherein the safety screw 32 and the spring pin assembly 33 are both used to connect the support plate 31 and the fixed base 2 to limit the rotation of the rotating mechanism 3 relative to the fixed base 2. In the original state of the bowl cleaning device, the rotating mechanism 3 and the cleaning mechanism 1 are fixed relative to the fixed base 2 and will not rotate.

[0039] The safety screw 32 is preferably a double safety short-axis screw, which ensures that when the cleaning mechanism 1 is hit, the fixed connection between the fixed base 2 and the support plate 31 can be released by disconnecting the double safety short-axis screw.

[0040] The spring pin assembly 33 is compressed in the initial state to ensure the fixed connection between the fixed base 2 and the support plate 31. When the cleaning mechanism 1 is hit, the spring pin assembly 33 is disconnected from the fixed base 2 to release the fixed connection between the fixed base 2 and the support plate 31.

[0041] Specifically, when the large bag on the rotary platform 02 rotates at a low position, the cleaning mechanism 1 of the bowl cleaning device 01 is hit, and the safety screw 32 and the spring pin assembly 33 are disconnected from the fixed base 2. At this time, the fixed base 2 and the support plate 31 of the rotating mechanism 3 are rotatably connected, and the support plate 31 can form a community with the cleaning mechanism 1 to rotate relative to the fixed base 2; during the disconnection of the safety screw 32, the collision force gradually decreases, and the spring pin assembly 33 is out of position but not damaged;

[0042] When the operation of the bowl cleaning device needs to be quickly restored, the spring pin assembly 33 is repositioned, and the support plate 31 and the fixed base 2 are fixed by the spare double-safety short-axis screws to ensure the normal operation of the cleaning mechanism 1, and then the subsequent processes are completed.

[0043] The bowl cleaning device comprises a cleaning mechanism 1, a fixed base 2 and a rotating mechanism 3, wherein the cleaning mechanism 1 is used to dock with the long water outlet for cleaning operations, one end of the fixed base 2 is fixed to the ground for support, and the other end of the fixed base 2 is rotatably connected to the rotating mechanism 3, and the rotating mechanism 3 is fixedly connected to the support plate 31 of the cleaning mechanism 1, that is, the fixed base 2 and the rotating mechanism 3 are a community and can rotate relative to the fixed base 2; the rotating mechanism 3 also comprises a safety screw 32 and a spring pin assembly 33, both of which are used to connect the support plate 31 and the fixed base 2 to limit rotation, and when the cleaning mechanism 1 is hit (large The safety screw 32 and the fixed base 2 are disconnected from the fixed base, and the force generated by the collision will decrease as the safety screw 32 is disconnected. The spring pin assembly 33 bounces off the fixed base 2 and is not damaged. At this time, the cleaning mechanism 1 and the rotating mechanism 3 as a whole can rotate relative to the fixed base; at this time, by resetting the spring pin assembly 33 and fixing the fixed base 3 and the support plate 31 by the safety screw 32, the bowl cleaning device has been reset, and the cleaning mechanism 1 is reset and continues to be fixed relative to the fixed base 2 by the rotating mechanism 3. The cleaning operation of the long water outlet can continue to be performed through the cleaning mechanism 1 without affecting the subsequent production process. The above-mentioned bowl cleaning device can be quickly reset after being hit, and the maintenance time is short, which can improve the working efficiency and ensure the long-term stability and reliability of the production process.

[0044] On the basis of the above embodiment, the spring pin assembly 33 includes a spring pin 331, and a chamfered pin hole matching the spring pin 331 is provided on the fixed base 2. A spring 333 is sleeved on the outer side of the spring pin 331, and one end of the spring 333 abuts against the surface of the support plate 31, and the other end of the spring 333 abuts against the threaded sleeve 332.

[0045] Please refer to Figures 1 to 3 The spring pin assembly 33 includes a spring pin 331 , a threaded sleeve 332 , and a spring 333 .

[0046] Among them, a chamfered pin hole matching with the spring pin 331 is provided on the fixed base 2, and the size and shape of the pin hole can be flexibly designed in combination with the structure of the spring pin 331 without any restriction.

[0047] A spring 333 is sleeved on the outer side of the spring pin 331, one end of the spring 333 abuts against the surface of the support plate 31, and the other end of the spring 333 abuts against the threaded sleeve 332. A shell is also provided on the outer side of the spring 333, which is the shell of the spring pin assembly 33. The inner wall of the shell is threadedly connected to the outer surface of the threaded sleeve 332. By twisting the threaded sleeve 332, the compression amount of the spring 333 can be adjusted, which can be flexibly changed.

[0052] Please refer to Figure 1-Figure 3 The rotating shaft 34 is arranged near the middle of the support plate 31 to ensure the stability of the fixed base 2 and the support plate 31 when they rotate relative to each other. The rotating shaft 34 has a portion protruding from the support plate 31, and a wrench 35 is threadedly connected to the portion. When the cleaning mechanism 1 is hit, the wrench 35 will also be offset. When the bowl cleaning device is reset as a whole, it can be judged by the position of the wrench 35 whether it has been accurately moved into place. There is no limitation on the specific size of the wrench 35, as long as it meets the usage requirements.

[0053] On the basis of any of the above embodiments, four groups of spring pin assemblies 33 are arranged along the length direction of the support plate 31 , and the four groups of spring pin assemblies 33 are symmetrically arranged on both sides of the rotating shaft 34 .
