Description

Technical Field

[0001] This application relates to the field of foaming technology, and in particular to a foam gun nozzle cleaning device. Background Technology

[0002] The foam gun, also known as the mixing head of a high-pressure foaming machine, is a core component in equipment for foaming and molding polyurethane and other polymer materials. The function of the foam gun is to precisely measure and mix various liquid chemical raw materials under high pressure and high-speed impact, and then inject them into the mold and cavity instantly to carry out chemical reactions and complete foaming.

[0003] During the use of a foaming gun, material residue will remain at the nozzle after each discharge. Therefore, the nozzle must be cleaned after each use to prevent material residue from clogging the nozzle outlet during the next use, which could reduce the diameter or even completely block the outlet, leading to defective or even scrapped products.

[0004] Currently, most foam gun nozzles are cleaned manually using blades periodically. However, manual cleaning is inconvenient and inefficient, and can easily lead to product spoilage due to untimely cleaning. Utility Model Content

[0005] To improve the cleaning efficiency of foam gun nozzles, this application provides a foam gun nozzle cleaning device.

[0006] This application provides a foam gun nozzle cleaning device, which adopts the following technical solution: A foam gun nozzle cleaning device includes a mounting plate, a blade for cleaning the foam gun nozzle, a drive component for moving the blade, and a blade holder for mounting the blade. The blade holder is mounted on the mounting plate. The drive component is also mounted on the mounting plate and is fixed to the blade, driving the blade to move on the blade holder. The blade holder has a locking interface for engaging with the nozzle, the axis of which is perpendicular to the movement trajectory of the blade. A cleaning chamber is formed inside the blade holder, and the cleaning chamber is connected to the locking interface and located within the movement trajectory of the blade.

[0007] By adopting the above technical solution, the foam gun head is snapped into the interface. At this time, the residual material at the end of the gun head is located in the cleaning chamber. Then, the driving component drives the blade to cut and clean the residual material in the gun head. The driving component replaces manual cleaning of the gun head, which solves the problems of low efficiency and inconvenience of manual cleaning.

[0008] Preferably, the blade holder has a clearance groove in the middle, the blade is slidably installed in the clearance groove and is arranged parallel to the mounting plate, the cleaning chamber is connected to the clearance groove, and the cleaning chamber is coaxially arranged with the card interface.

[0009] By adopting the above technical solution, the clearance groove of the blade holder provides a precise sliding track for the blade, preventing the blade from shifting during cutting and ensuring the consistency of the cutting position; the cleaning chamber and the card interface are coaxially set and connected to the clearance groove, so that the residual material cut inside the gun head can fall directly into the clearance groove for easy centralized processing.

[0010] Preferably, the blade size is adapted to the clearance groove size so as to push the cut residue out of the clearance groove.

[0011] By adopting the above technical solution, when the blade slides under the drive of the drive component, since the size is adapted to the clearance groove, the drive component continues to drive the blade to slide in the clearance groove. After the blade cuts the residual material, it can simultaneously push the residual material that fell into the clearance groove out of the groove, eliminating the need for manual cleaning of the accumulated material in the clearance groove and improving cleaning efficiency.

[0012] Preferably, the blade has a lubrication groove for storing lubricating fluid, and the lubrication groove passes under the cleaning chamber along the movement trajectory of the blade.

[0013] By adopting the above technical solution, after the driving component drives the blade to clean the gun head, the driving component continues to drive the blade to slide in the clearance groove. The lubrication groove on the blade gradually moves to the bottom of the gun head. At this time, the lubricant in the lubrication groove comes into contact with the gun head to form a protective film, thereby reducing the adhesion of the foaming agent at the gun head. On the one hand, this makes it more difficult for the foaming agent to adhere to the gun head, and on the other hand, it makes it easier for the residual material to be scraped off by the blade, reducing the secondary dripping of the residual material.

[0014] Preferably, the tool holder has an addition hole for adding lubricating fluid into the lubrication groove, the axis of the addition hole being perpendicular to the mounting plate and communicating with the clearance groove.

[0015] By adopting the above technical solution, lubricant can be directly added to the lubrication groove of the blade through the added hole. The operation is simple, the downtime for equipment maintenance is reduced, and the work efficiency is improved.

[0016] Preferably, the cleaning chamber is a cylindrical groove, the axis of the cleaning chamber is perpendicular to the mounting plate, and the cleaning chamber is coaxially arranged with the card interface.

[0017] By adopting the above technical solution, on the one hand, the cylindrical groove is easy to process and convenient to manufacture; on the other hand, the cylindrical fitting interface shape allows the residual material on the gun head to continue to contact the inner wall of the cleaning chamber when it enters the cleaning chamber. When the blade cuts the residual material, the residual material is squeezed and cut by the force of the inner wall of the cleaning chamber and the force of the blade at the same time, which improves the cutting quality.

[0018] Preferably, the driving component is a cylinder, the output shaft of the driving component is arranged parallel to the mounting plate, and the end of the output shaft of the driving component is fixed to one side of the blade.

[0019] By adopting the above technical solution, the cylinder is small in size and easy to install. The parallel mounting plate of the output shaft is set to match the movement direction of the blade, eliminating the need for additional transmission components and reducing the complexity of the device.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. Insert the foam gun nozzle into the mounting hole of the cleaning chamber, and then drive the blade to slide in the relief groove to cut the residual material on the nozzle. The blade is perpendicular to the nozzle and can directly cut off the residual material on the nozzle, avoiding nozzle clogging. The drive mechanism replaces manual cleaning of the nozzle, solving the problems of low efficiency and inconvenience of manual cleaning. 2. After the drive unit drives the blade to clean the gun head, the drive unit continues to drive the blade to slide in the clearance groove. The lubrication groove on the blade gradually moves to the bottom of the gun head. At this time, the lubricant in the lubrication groove comes into contact with the gun head to form a protective film, so as to reduce the adhesion of the foam at the gun head and make the residue easier to be scraped off by the blade, reducing secondary dripping. 3. Lubricant can be added directly to the lubrication groove of the blade through the addition hole, which is simple to operate, reduces downtime for equipment maintenance, and improves work efficiency.

(Reference) Figure 2 The blade 2 is slidably installed in the clearance groove 7, that is, the blade 2 is parallel to the mounting plate 1.

Then the driving component 4 continues to drive the blade 2 to slide forward and push the cut material out of the relief groove 7. At the same time, the lubricating liquid in the lubrication groove 8 comes into contact with the gun head to lubricate it. The driving component 4 replaces manual cleaning of the gun head, which solves the problems of low efficiency and inconvenience of manual cleaning.
