[0002] During the production of a foaming line, the foaming gun needs to reciprocate multiple times to inject foaming material into multiple parts.

[0003] During long-term use, there will be a dripping phenomenon after the foaming gun head discharges material. Therefore, the foaming gun head needs to be cleaned after each use to avoid the problem of secondary dripping during the next use and improve the stability of product quality.

[0004] However, at present, the foaming gun head is mostly cleaned manually with a blade regularly, which is inconvenient to clean and has low cleaning efficiency. At the same time, when cleaning the foaming gun head with different color foaming materials, it is easy to contaminate the product and even cause the product to be scrapped.

[0005] Meanwhile, if the gun head of the foaming gun is not cleaned for a long time, the remaining foaming material will accumulate on the gun head, which will not only affect the injection quality, but seriously cause the foaming glue to be unable to be used normally.

[0006] For the traditional equipment for cleaning the foaming gun head, although it can clean the foaming gun head to a certain extent; for example, the content disclosed in the patent 202122195876.4 - NVH foaming gun head electric cleaning equipment; however, the existing cleaning equipment uses a brush for cleaning, the brush material is relatively soft, and the cleaning effect on the remaining foaming is not good; at the same time, the brush is easy to be damaged and has a low service life.

[0033] Next, with reference to the accompanying drawings, through the description of the optimal embodiments, the detailed implementation manners of the present utility model will be further described in detail.

[0034] A cleaning device for the outer circle of a foaming gun head 102 includes a cleaning mechanism 1-2, and the cleaning mechanism 1-2 is connected with a control mechanism, and the control mechanism can control the action of the cleaning mechanism 1-2; through the combined use of the cleaning mechanism 1-2 and the control mechanism in the present utility model, by changing the position of the cleaning mechanism 1-2 by the control mechanism, the cleaning mechanism 1-2 acts on the foaming gun head 102 to be cleaned, so as to realize the cleaning operation of the residual foaming material at the end of the foaming gun head 102.

[0035] The cleaning device 1-1 disclosed in the present utility model is mainly used for cleaning the foaming gun head 102 after use, which is beneficial to ensuring the cleanliness of the foaming gun head 102 and facilitating the subsequent use of the foaming gun.

[0036] In the present utility model, the cleaning mechanism 1-2 includes a cleaning plate 1-21; in the present utility model, the cleaning plate 1-21 acts as a scraping plate; driven by the control mechanism, the cleaning plate 1-21 rotates circumferentially around the gun head 102, so as to realize the corresponding material removal operation.

[0037] In the present utility model, the control mechanism can control the cleaning plate 1-21 to rotate along the circumference of the foaming gun head 102 to be cleaned; the cleaning plate 1-21 of the present utility model is arranged close to the gun head 102, and the cleaning plate 1-21 acts as a scraping plate, so that the cleaning plate 1-21 removes the residual liquid material at the gun head 102.

[0038] In the present utility model, the cleaning plate 1-21 includes a plate body which is the main structure of the cleaning plate 1-21. In the present utility model, the plate body includes a base plate 1-211, and a scraping block 1-212 is provided on the side of the base plate 1-211. The base plate 1-211 is the main structure of the plate body, and the scraping block 1-212 mainly interacts with the gun head 102 to realize the scraping operation on the gun head 102. In the present utility model, the scraping block 1-212 is a triangular prism with an isosceles triangle in horizontal projection; such a setting makes the side of the scraping block 1-212 close to the gun head 102 equivalent to having an edge, which is convenient for the subsequent scraping operation of the gun head 102.

[0039] Further, in the present utility model, the control mechanism includes a rotating component 1-4; the rotating component 1-4 includes a rotary cylinder; the rotary cylinder can drive the cleaning mechanism 1-2 to rotate; by rotating the cleaning plate 1-21 on the circumference of the gun head 102 to be cleaned, the residual material on the circumference of the gun head 102 can be removed; in other words, through the setting of the rotating component 1-4, it is convenient to drive the cleaning mechanism 1-2 to rotate during subsequent use, so as to remove the residual material on the outer circumference of the gun head 102.

[0040] Further, in the present utility model, the control mechanism further includes a clamping component 1-3; the clamping component 1-3 includes a pneumatic chuck; the chuck 1-31 on the pneumatic chuck is connected to the corresponding cleaning plate 1-21; the clamping pneumatic chuck is an existing structure. The basic function of the clamping pneumatic chuck in the present utility model is to facilitate the installation and connection of the cleaning plate 1-21 on the pneumatic chuck. At the same time, because the chuck 1-31 of the pneumatic chuck can be retracted, during subsequent use, the interval between the cleaning plate 1-21 and the gun head 102 can be changed according to needs, so as to realize the cleaning operation on the gun head 102.

[0041] Further, in the present utility model, the cleaning plate 1-21 and the chuck 1-31 are connected by a detachable connection method; they are connected by bolts. Generally, stepped holes are designed along the height direction of the cleaning plate 1-21, and the bolts pass through the stepped holes and are connected to the corresponding chuck 1-31, so as to realize the connection between the cleaning plate 1-21 and the chuck 1-31.

[0042] In the present utility model, the cleaning plate 1-21 is generally connected to the corresponding chuck 1-31 at intervals with two screws. Based on such a setting, the stability of the installation of the cleaning plate 1-21 on the chuck 1-31 is ensured.

[0043] Further, in the present utility model, a limiting portion is provided between the cleaning plate 1-21 and the clamping jaw 1-31; the limiting portion mainly plays a positioning role and at the same time avoids the cleaning plate 1-21 from moving laterally on the clamping jaw 1-31 during subsequent cleaning; specifically, the limiting portion includes a sunk groove 1-311 provided on the clamping jaw 1-31 and a clamping block 1-22 provided at the end of the plate body; the sunk groove 1-311 on the clamping jaw 1-31 and the clamping block 1-22 on the plate body cooperate with each other, so that the end of the plate body is equivalent to being inserted into the clamping jaw 1-31, thus avoiding the lateral movement of the cleaning plate 1-21 on the clamping jaw 1-31.

[0044] Further, in the present utility model, the cleaning mechanism 1-2 includes a plurality of cleaning plates 1-21, and the plurality of cleaning plates 1-21 are evenly distributed at intervals in a ring on the pneumatic chuck; based on such a setting, the cleaning mechanism 1-2 as a whole forms a ring-shaped structure. During subsequent use, the plurality of cleaning plates 1-21 can be evenly distributed around the circumference of the gun head 102, so that the cleaning operation of the gun head 102 can be realized from multiple positions of the gun head 102 through the cleaning plates 1-21.

[0045] Further, in the present utility model, the plurality of cleaning plates 1-21 are symmetrically distributed on the pneumatic chuck; although axial symmetry is feasible for the symmetry here, the best symmetry method is required to be centrosymmetric; the reason for requiring symmetric distribution here is to ensure the consistency of the external force applied by the cleaning plates 1-21 to the gun head 102 and avoid cleaning damage caused by large differences in the forces received by the gun head 102.

[0046] A cleaning assembly for a foaming line includes a support frame 1, and a plurality of cleaning devices 1-1 are provided on the support frame 1; in the present utility model, the support frame 1 is a support foundation, which facilitates the installation and arrangement of the cleaning devices 1-1; in the present utility model, the support frame 1 can realize the layout and security of the cleaning assembly on the production line. At the same time, a plurality of cleaning devices 1-1 are provided on the support frame 1, so that the cleaning operation at multiple positions can be realized, which is beneficial to ensuring the cleaning operations of multiple foaming guns.

[0047] Further, in the present utility model, a receiving box 101 is arranged below each cleaning device 1-1; the receiving box 101 can collect the residual materials scraped by the cleaning plate 1-21 and avoid the scattering of the residual materials after scraping.

[0048] Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model, they are all within the protection scope of the present utility model.
