Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, specifically a defoaming device for the production of water-based adhesives. Background Technology

[0002] To ensure human health, the variety of adhesives is increasing, mainly focusing on water-based, solid, solvent-free, and low-toxicity formulations. Among them, water-based polyurethane adhesives are non-toxic and do not release organic solvents, making them highly popular and widely used in printing and food packaging.

[0003] According to the announcement number CN220824500U, a defoaming device for adhesive production aims to solve the technical problem that current traditional defoaming devices for adhesive production simply use stirring to eliminate bubbles, resulting in a relatively simple defoaming method that cannot efficiently and quickly eliminate bubbles. The device includes a cylindrical body and a rotating tube rotatably mounted inside the cylindrical body, with one side of the rotating tube passing through the cylindrical body. A defoaming mechanism is connected to the upper and lower ends of the rotating tube. This invention utilizes two rotating joints to connect with the rotating tube. A water pump draws hot water from a water tank and inputs it into the rotating tube and multiple connecting pipes, thereby eliminating bubbles in the adhesive through heat. Furthermore, during the heat-induced defoaming process, a motor can be activated, driving gears and the rotating tube to rotate. The rotating tube then drives the connecting pipes to rotate, further agitating and eliminating bubbles in the adhesive, achieving dual defoaming through both heat and agitation.

[0004] The above-mentioned device can achieve dual defoaming through heat and agitation, and has certain practicality. According to the instruction manual and the attached drawings, the adhesive has high adhesion and is easy to remain on the inner wall and component surface after the equipment is shut down. The pipeline is an integral structure and cannot be disassembled to clean the internal residue. Utility Model Content

[0005] The purpose of this invention is to provide a defoaming device for the production of water-based adhesives, which addresses the problem that adhesives have high adhesion and tend to remain on the inner walls and surfaces of components after equipment shutdown, and that the pipes are integral structures that cannot be disassembled to clean the internal residues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a defoaming device for the production of water-based adhesives, comprising a water pipe connected in a continuous manner to a pipeline, connecting pipes symmetrically arranged around the water pipe, and a connecting net arranged in the middle of the two sets of connecting pipes. One end of the pipeline is provided with a sealing pipe cover, which is slidably connected to the water pipe. One end of the sealing pipe cover is fixedly installed with an installation cover. A limiting rod is slidably connected around the inside of the installation cover. A limiting slot is uniformly opened around the inside of the pipeline, and the limiting slot is adapted to the limiting rod. A cavity is opened inside the installation cover, and a rotating disk is rotatably connected inside the cavity. Tooth blocks are uniformly fixedly installed around the inner side of the rotating disk.

[0007] As a further embodiment of this utility model: a rotating shaft is rotatably connected inside the cavity, a connecting gear is fixedly installed at one end of the rotating shaft, and the connecting gear meshes with the tooth block; a driving gear is fixedly installed on the outer periphery of the rotating shaft; and a rack is fixedly installed at one end of the limiting rod, and the rack meshes with the driving gear.

[0008] As a further embodiment of this utility model: one end of the sealing tube cap is rotatably connected to a rotating handle, and the rotating handle is fixedly installed with the rotating disc, and the rotating handle is connected to the water pipe.

[0009] As a further embodiment of this utility model: a limiting gear is fixedly installed at one end of the rotating handle, a groove is opened at one end of the sealing tube cover, and a limiting rod is slidably connected inside the groove. The limiting rod is adapted to the tooth groove of the limiting gear, and a damping spring is fixedly installed inside the groove, with one end of the damping spring fixedly installed to the limiting rod.

[0010] As a further improvement of this utility model: a sealing groove is provided at one end of the sealing pipe cap, and a sealing ring is fixedly installed at one end of the pipe, and the sealing ring is adapted to the sealing groove.

[0011] As a further improvement of this utility model: a guide block is symmetrically fixedly installed on the outer periphery of one end of the mounting cover, and a guide groove is symmetrically opened inside the pipe, and the guide groove is adapted to the guide block.

[0012] As a further improvement of this utility model: a water tank is provided around the water pipe, and a water pump is provided around the water pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model unlocks the pipe by pulling the limit rod, drives the limit rod to disengage from the limit slot by rotating the handle, and opens one end of the pipe by pulling the sealing cap along the water pipe. Workers can directly contact the inner wall of the pipe and the surface of the components to thoroughly clean the highly adhesive residue, avoid the residue from affecting the subsequent defoaming effect or clogging the pipe, and ensure the long-term stable operation of the device.

[0015] During installation, the sealing ring is embedded in the sealing groove to form the first seal, and the limiting rod is inserted into the limiting slot to fix the structure. At the same time, the damping spring pushes the limiting rod to lock the limiting gear, preventing the limiting rod from loosening due to accidental rotation of the handle. The combination of multiple sealing and locking structures ensures that there is no leakage of adhesive and defoaming medium during device operation, improving operational safety and stability.

[0024] Reference Figures 1 to 5 In this embodiment of the present invention, a defoaming device for the production of water-based adhesives includes a water pipe 2 connected to a pipe 1, connecting pipes 3 symmetrically arranged around the water pipe 2, and a connecting mesh 4 arranged in the middle of the two sets of connecting pipes 3. A sealing cap 5 is provided at one end of the pipe 1, and the sealing cap 5 is slidably connected to the water pipe 2. An installation cap 6 is fixedly installed at one end of the sealing cap 5. A limiting rod 8 is slidably connected around the inside of the installation cap 6. A limiting slot 7 is uniformly formed around the inside of the pipe 1, and the limiting slot 7 is adapted to the limiting rod 8. A cavity 9 is formed inside the installation cap 6. A rotating disk 10 is rotatably connected inside cavity 9, and toothed blocks 11 are evenly and fixedly installed around the inner side of rotating disk 10. A rotating shaft 12 is rotatably connected inside cavity 9, and a connecting gear 13 is fixedly installed at one end of rotating shaft 12, and the connecting gear 13 meshes with toothed blocks 11. A driving gear 14 is fixedly installed on the outer periphery of rotating shaft 12. A rack 15 is fixedly installed at one end of limiting rod 8, and the rack 15 meshes with driving gear 14. A rotating handle 16 is rotatably connected to one end of sealing tube cover 5, and the rotating handle 16 is fixedly installed with rotating disk 10. The rotating handle 16 is connected to water pipe 2.

[0025] The above scheme is adopted as follows: the sealing cap 5 at one end of the pipe 1 is made of stainless steel and is slidably connected to the water pipe 2. The mounting cap 6, which is welded and fixed at one end of the sealing cap 5, is made of alloy material with strong structural rigidity and anti-corrosion treatment. The limiting plug 8, which is uniformly wrapped around the inside and is slidably connected, is made of stainless steel with chrome plating for rust prevention and has a chamfered end for easy insertion. The inner wall of the limiting slot 7, which is uniformly wrapped around the inside of the pipe 1, is smooth. The inner wall of the cavity 9, which is opened inside the mounting cap 6, is regular. The rotating disk 10, which is rotatably connected by a deep groove ball bearing, is made of alloy material. The toothed blocks 11, which are uniformly wrapped around the inside and welded and fixed, are made of 20Cr material with hardened tooth surface treatment. With a hardness of HRC55-58, the rotating shaft 12 inside the cavity 9, which is connected by a bearing, is made of steel. The connecting gear 13, which is welded and fixed at one end, is made of the same material and process as the tooth block 11. The driving gear 14, which is welded and fixed on the outer periphery of the rotating shaft 12, is made of the same material and process as the connecting gear 13. The rack 15, which is welded and fixed at one end of the limiting rod 8, is made of stainless steel. The rotating handle 16, which is connected to the sealing tube cover 5 by a bearing, is made of engineering plastic with a metal core. The model is ABS+PC, which takes into account both anti-slip feel and impact resistance. It is welded and fixed to the rotating disk 10. The rotating handle 16 is connected to the water pipe 2 through the pipe, and a sealing ring is set at the through point to prevent fluid leakage.

[0026] Reference Figures 1 to 5 A limiting gear 17 is fixedly installed at one end of the rotating handle 16, and a groove 18 is opened at one end of the sealing tube cover 5. A limiting rod 19 is slidably connected inside the groove 18. The limiting rod 19 is adapted to the tooth groove of the limiting gear 17. A damping spring 20 is fixedly installed inside the groove 18, and one end of the damping spring 20 is fixedly installed with the limiting rod 19.

[0027] The above-mentioned scheme is adopted as follows: the rotating handle 16 is an engineering plastic encasing a metal core, model ABS+PC; the limiting gear 17, which is welded and fixed at one end, is made of 20CrMnTi alloy steel; the groove 18 at one end of the sealing tube cap 5 has a smooth inner wall, providing installation space for the limiting components; the internally sliding limiting rod 19 is made of stainless steel with a chrome-plated surface for rust prevention, and precisely matches the tooth groove of the limiting gear 17; the damping spring 20, which is welded and fixed inside the groove 18, is a cylindrical helical compression spring, model YI-C10-15, which has excellent damping characteristics and fatigue resistance, and stable elastic force. One end is welded and fixed to the limiting rod 19. The advantage of this structure is that, under normal conditions, the damping spring 20 pushes the limiting rod 19 into the limiting position. The tooth groove of the positioning gear 17 mechanically locks the rotation state of the rotating handle 16, preventing the rotating handle 16 from rotating due to vibration, accidental contact, or fluid impact. This prevents the limiting rod 8 from dislodging from the limiting slot 7, ensuring the connection stability between the sealing cap 5 and the pipeline 1 and preventing fluid leakage. The damping characteristics of the damping spring 20 can buffer the impact force when the limiting rod 19 meshes with the limiting gear 17, reducing component wear. At the same time, it ensures that the limiting rod 19 can be stably kept in the tooth groove, avoiding limit failure due to slight vibration. When it is necessary to adjust the rotating handle 16, simply press the limiting rod 19 into the groove 18 to compress the damping spring 20 and disengage it from the tooth groove of the limiting gear 17 to release the lock. The operation is convenient and labor-saving.

[0028] Reference Figures 1 to 5 The sealing pipe cover 5 has a sealing groove 22 at one end, and a sealing ring 21 is fixedly installed at one end of the pipe 1. The sealing ring 21 is adapted to the sealing groove 22. The mounting cover 6 has guide blocks 23 symmetrically fixedly installed on the outer periphery of one end. The pipe 1 has guide grooves symmetrically opened inside, and the guide grooves are adapted to the guide blocks 23.

[0029] The above scheme is adopted: the inner wall of the sealing groove 22 at one end of the sealing pipe cover 5 is smooth; the sealing ring 21 welded and fixed at one end of the pipe 1 is made of nitrile rubber, model NBR-70, which has excellent oil resistance and sealing properties, a smooth surface without bubbles, and a precise fit with the sealing groove 22, forming a tight sealing surface after fitting; the guide block 23 symmetrically welded and fixed to the outer circumference of one end of the mounting cover 6 is made of stainless steel, with a chrome-plated surface for rust prevention, and one end is chamfered for easy insertion; the inner wall of the guide groove symmetrically opened inside the pipe 1 is polished, with low sliding resistance, and it precisely matches the guide block 23. The advantage of this structure is that when installing the sealing pipe cover 5, the guide block 23 moves along the pipe... The sliding of the guide groove of the guide tube 1 provides precise guidance for the sealing tube cap 5, ensuring that the sealing ring 21 can be smoothly embedded into the sealing groove 22. This avoids misalignment and deformation of the sealing ring 21 due to the offset of the sealing tube cap 5, thus ensuring the integrity of the sealing structure. After the sealing ring 21 is embedded into the sealing groove 22, the elasticity of the nitrile rubber material can fill the tiny gap between the sealing tube cap 5 and the pipe 1. At the same time, under the action of fluid pressure, it further adheres to the sealing surface, forming a double sealing effect, effectively preventing fluid leakage. The cooperation between the guide block 23 and the guide groove can also ensure that the limiting rod 8 on the mounting cover 6 is precisely aligned with the limiting slot 7 of the pipe 1, avoiding the rod from being offset and unable to be inserted, thus improving installation efficiency.

[0030] Reference Figures 1 to 5 A water tank 24 is installed around the water pipe 2, and a water pump 25 is installed around the water pipe 2.

[0031] The above-mentioned scheme is adopted: both water tank 24 and water pump 25 are prior art referenced in the prior art documents, and are not described in detail in this application.

[0032] The working principle of this utility model is as follows: When the equipment is stopped and the residue on the inner wall needs to be cleaned, first pull the limiting rod 19 in the groove 18 at one end of the sealing pipe cover 5 to compress the damping spring 20 in the groove 18, so that the limiting rod 19 disengages from the tooth groove of the limiting gear 17 at one end of the rotating handle 16, thereby releasing the rotation lock on the rotating handle 16. Then, rotate the rotating handle 16 to drive the rotating disk 10 in the cavity 9 of the mounting cover 6 to rotate synchronously. The tooth block 11 on the inner side of the rotating disk 10 meshes with the connecting gear 13 at one end of the rotating shaft 12 in the cavity 9, driving the rotating shaft 12 to rotate. The driving gear 14 on the outer periphery of the rotating shaft 12 rotates accordingly and meshes with the rack 15 at one end of the limiting rod 8, driving multiple sets of limiting rods 8 to slide synchronously into the cavity 9 along the mounting cover 6 until the limiting rods 8 completely disengage from the limiting slot 7 of the pipe 1, thus releasing the sealing pipe cover. 5. After fixing the pipe 1, pull the sealing cap 5 outward along the water pipe 2. The guide block 23 at one end of the cap 6 slides along the guide groove inside the pipe 1 to ensure that the sealing cap 5 is smoothly removed from the pipe 1. At this time, one end of the pipe 1 is completely open, and the staff can directly clean the adhesive residue on the surface of the inner wall and other components of the pipe 1. After cleaning, push the sealing cap 5 back to its original position along the water pipe 2 so that the guide block 23 is re-embedded in the guide groove and the sealing ring 21 is inserted into the sealing groove 22. Rotate the handle 16 in the opposite direction. Through the linkage of the toothed block 11, the connecting gear 13, the drive gear 14 and the rack 15, push the limit rod 8 to reset and be inserted into the limit slot 7. Release the limit rod 19, and the damping spring 20 pushes it to reset and lock the limit gear 17, thus completing the fixing of the sealing cap 5. The device can then be put back into defoaming operation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
