Description

Technical Field

[0001] This application relates to the technical field of gun head cleaning, for example, to a gun head cleaning device. Background Art

[0002] The refrigerator foaming process is one of the crucial links in the modern refrigerator manufacturing process. The foaming process mainly injects polyurethane foam into the insulation layer of the refrigerator to provide excellent heat insulation performance. However, during the foaming process, the foaming gun head is a key component directly involved in the injection of polyurethane foam, and its working state directly affects the foaming quality and production efficiency. In actual production, the foaming gun head often has problems such as foam residue and blockage due to long-term use. This not only leads to a decline in foaming quality but may also cause the production line to stop, increasing maintenance costs and time.

[0003] Therefore, after the injection of the refrigerator door body and the box body foaming injection gun head is completed, the gun head needs to be cleaned. A welding torch cleaning device is disclosed in the related art. The welding torch cleaning device includes a clamping mechanism and a reaming slag mechanism. The clamping mechanism includes a clamping power mechanism installed on the machine body and two clamping blocks with centering grooves. The two clamping blocks are driven by the clamping power mechanism to move synchronously towards or away from each other. When the two clamping blocks move towards each other, the centering grooves of the two clamping blocks form a welding torch clamp that clamps and fixes the welding torch protective sleeve directly above the reamer.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] The reamer of the reaming slag mechanism in the related art can clean the welding slag of the welding torch, but after the cleaning, the welding slag will fall on the reaming slag mechanism and the ground, and the operating environment of the reamer mechanism is relatively poor. Especially when the welding slag falls into the gap, it is easy to cause wear between the moving parts of the reaming slag mechanism, and the cleanliness and working reliability of the reaming slag mechanism during use are relatively poor.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0044] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0045] The embodiments of the present disclosure provide a gun head cleaning device, such as Figures 1 to 9As shown, the gun head cleaning device includes a clamping mechanism 100, a cleaning mechanism 200, and a collection mechanism 300. The clamping mechanism 100 includes a first driving member 110 and a clamping jaw 120 that are connected. The first driving member 110 is used to drive the clamping jaw 120 to open and close, and the clamping jaw 120 is used to lock or unlock the gun head 400. The cleaning mechanism 200 includes a reamer 210 that can extend into the gun head 400 to clean the gun head 400. The collection mechanism 300 includes a jetting member 310 and a material receiving box 320. The air outlet of the jetting member 310 faces the reamer 210, and the material receiving box 320 is arranged below the cleaning mechanism 200. The material receiving box 320 is used to receive the debris in the gun head 400 blown off by the jetting member 310.

[0046] In this embodiment, the clamping mechanism 100 includes a first driving member 110 and a clamping jaw 120 that are connected. The cleaning mechanism 200 includes a reamer 210 that can clean the gun head 400. The collection mechanism 300 includes a jetting member 310 that can jet air towards the reamer 210 and a material receiving box 320 that can receive debris. In this way, when the gun head 400 is working, the first driving member 110 drives the clamping jaw 120 to open, and the clamping jaw 120 unlocks the gun head 400 so that the gun head 400 moves to the working area for work. After the gun head 400 finishes working, the gun head 400 moves to the clamping jaw 120, and the first driving member 110 drives the clamping jaw 120 to close, and the clamping jaw 120 locks the gun head 400. The reamer 210 of the cleaning mechanism 200 extends into the gun head 400 to clean the gun head 400. The debris generated by the reamer 210 cleaning the gun head 400 flows out along with the reamer 210, and the jetting member 310 blows the debris into the material receiving box 320, completing the cleaning of the gun head 400 and the cleaning mechanism 200 so that the gun head 400 can perform the next working cycle.

[0047] Adopting this alternative embodiment, the clamping mechanism 100 and the cleaning mechanism 200 can clamp and automatically clean the gun head 400, reducing manual operation and improving production and cleaning efficiency. Through the combined use of the jetting member 310 and the material receiving box 320, the debris generated during the cleaning process can be collected in a timely and effective manner, improving the environmental cleanliness during the use of the cleaning device and reducing the pollution of the surrounding environment and equipment by the debris. Moreover, the debris generated during the cleaning process can be collected, reducing the occurrence of wear of the debris on the moving parts of the gun head cleaning device, and improving the working reliability and service life of the gun head cleaning device.

[0048] In some alternative embodiments, as Figure 1 shown, the gun head cleaning device further includes a mounting bracket 500. The clamping mechanism 100, the cleaning mechanism 200, and the material receiving box 320 are respectively connected to the mounting bracket 500 and are arranged in sequence along the height direction of the mounting bracket 500.

[0049] In this embodiment, the clamping mechanism 100, the cleaning mechanism 200, and the material receiving box 320 are respectively connected to the mounting frame 500 along the height direction of the mounting frame 500, that is, the clamping mechanism 100, the cleaning mechanism 200, and the material receiving box 320 are arranged in sequence from top to bottom, so that the debris of the clamping mechanism 100 and the cleaning mechanism 200 can fall into the material receiving box 320, improving the environmental cleanliness during the use of the cleaning device and reducing the pollution of the debris to the surrounding environment and equipment. And the mounting frame 500 provides stable support for each component, ensuring the stability of the gun head cleaning device during the working process. The fixed connection of the clamping mechanism 100, the cleaning mechanism 200, and the material receiving box 320 reduces the relative movement between the components, improving the overall stability and working reliability of the device.

[0050] In some alternative embodiments, such as Figure 2 , Figure 3 and Figure 5 shown, the jaw 120 includes a first sub-jaw 121 and a second sub-jaw 122. The first sub-jaw 121 is provided with a first half groove, and the second sub-jaw 122 is provided with a second half groove. The side walls of the first half groove and the second half groove are used to clamp the gun head 400.

[0051] In this embodiment, the first sub-jaw 121 is provided with a first half groove, and the second sub-jaw 122 is provided with a second half groove. When the first sub-jaw 121 and the second sub-jaw 122 are closed, the first half groove and the second half groove together form a complete clamping groove to clamp and lock the gun head 400. This can better wrap and clamp the gun head 400, improving the clamping effect and enhancing the stability of the gun head 400 during the cleaning process.

[0052] When the first sub-jaw 121 and the second sub-jaw 122 are opened, the first half groove and the second half groove are separated, enabling the gun head 400 to move freely to complete operations such as spraying materials.

[0053] Optionally, the material of the first sub-jaw 121 and / or the material of the second sub-jaw 122 is polyurethane material. Polyurethane material has characteristics such as high toughness and high wear resistance. The material of the jaw 120 being polyurethane material can reduce the wear and damage generated during use, increasing the service life of the jaw 120. And polyurethane material has elasticity and shock absorption performance. When clamping the gun head 400, it can absorb and relieve the impact force during the clamping process, reducing the instantaneous impact and damage to the gun head 400. Compared with the traditional metal jaw 120, the polyurethane jaw 120 can better protect the integrity of the gun head 400.

[0054] In some embodiments, such as Figures 2 to 6As shown, the clamping mechanism 100 further includes a wedge block 130, a first driven block 140, and a second driven block 150. The wedge block 130 is connected to the driving end of the first driving member 110. The first driving member 110 can drive the wedge block 130 to move in the first direction. The wedge block 130 includes a first side wall and a second side wall that are inclined to the first direction, and the first side wall and the second side wall are respectively located on both sides of the wedge block 130 along the first direction.

[0055] The first driven block 140 includes a third side wall, and the third side wall is docked with the first side wall. The first side wall can drive the first driven block 140 to move in a second direction intersecting the first direction. The first sub-jaw 121 is connected to the first driven block 140. The second driven block 150 includes a fourth side wall, and the fourth side wall is docked with the second side wall. The second side wall can drive the second driven block 150 to move in the second direction. The second sub-jaw 122 is connected to the second driven block 150.

[0056] In this embodiment, the driving end of the first driving member 110 is connected to the wedge block 130, and the first driving member 110 can drive the wedge block 130 to move in the first direction. The first side wall and the second side wall are respectively located on both sides of the wedge block 130 along the first direction. The third side wall of the first driven block 140 is docked with the first side wall, and the fourth side wall of the second driven block 150 is docked with the second side wall. That is to say, the first driven block 140 and the second driven block 150 are respectively located on both sides of the wedge block 130. The first side wall and the second side wall are inclined to the first direction. In this way, when the wedge block 130 moves in the first direction, the first side wall and the second side wall can respectively provide acting forces intersecting the first direction to the first driven block 140 and the second driven block 150. Therefore, when the wedge block 130 moves in the first direction, the first driven block 140 and the second driven block 150 can be driven to move in the second direction by the inclined first side wall and second side wall, and the movement directions of the first driven block 140 and the second driven block 150 are opposite.

[0057] The first sub-jaw 121 is connected to the first driven block 140, and the second sub-jaw 122 is connected to the second driven block 150. The first driven block 140 and the second driven block 150 can move synchronously and in opposite directions under the drive of the first driving member 110 and the wedge block 130 to realize the opening and closing of the first sub-jaw 121 and the second sub-jaw 122. In this embodiment, two sub-jaws 120 can be driven by one first driving member 110, reducing the use of driving components and lowering the production cost.

[0058] Optionally, the first driving member 110 includes a telescopic cylinder, and the telescopic part of the telescopic cylinder is connected to the wedge block 130. In this way, the wedge block 130 can be driven to reciprocate in the first direction, thereby driving the first sub-jaw 121 and the second sub-jaw 122 to reciprocate in the second direction to realize the opening and closing of the jaws 120.

[0059] Optionally, the first driving member 110 includes a motor, a gear, and a rack. The output shaft of the motor is connected to the gear, the gear meshes with the rack, and the rack is connected to the wedge block 130. In this embodiment, the rack is the driving part of the first driving member 110. The motor drives the gear to rotate, the gear drives the rack to reciprocate in the first direction, and the rack drives the wedge block 130 to reciprocate in the first direction, thereby driving the first sub-jaw 121 and the second sub-jaw 122 to reciprocate in the second direction to realize the opening and closing of the jaw 120.

[0062] Optionally, the first limiting groove 141 is a dovetail groove, and the shape of the first limiting protrusion 131 is adapted to the shape of the first limiting groove 141.

The second limiting protrusion 132 is arranged in the second limiting groove 151, and the second limiting protrusion 132 can slide relative to the second limiting groove 151.

[0064] For example, the second side wall is provided with the second limiting groove 151, and the third side wall is provided with the second limiting protrusion 132; and / or, as Figure 6As shown, the second side wall is provided with a second limiting protrusion 132, and the third side wall is provided with a second limiting groove 151.

[0065] Optionally, the second limiting groove 151 is a dovetail groove, and the shape of the second limiting protrusion 132 is adapted to the shape of the second limiting groove 151.

[0066] In some alternative embodiments, as Figures 2 to 6 shown, the clamping mechanism 100 further includes a fixed frame 160. The fixed frame 160 is configured with an installation space. The wedge block 130, the first driven block 140, and the second driven block 150 are arranged in the installation space. The inner side wall of the installation space is provided with a positioning portion 161. The limiting portion extends in the second direction. The first driven block 140 and the second driven block 150 are respectively provided with a positioning and mating portion 162. The positioning and mating portion 162 is adapted to the positioning portion 161, and the positioning and mating portion 162 can slide relative to the positioning portion 161 to define the moving directions of the first driven block 140 and the second driven block 150; wherein, the second direction is perpendicular to the first direction.

[0067] In this embodiment, by providing the positioning portion 161 in the installation space of the fixed frame 160 and providing the positioning and mating portion 162 adapted to the positioning portion 161 on the first driven block 140 and the second driven block 150, the moving directions of the first driven block 140 and the second driven block 150 can be defined, enabling the first sub-jaw 121 and the second sub-jaw 122 to open and close along the second direction.

[0068] The second direction is perpendicular to the first direction, that is, the moving directions of the first driven block 140 and the second driven block 150 are perpendicular to the moving direction of the wedge block 130. In this way, the moving speeds of the first driven block 140 and the second driven block 150 can be the same, improving the synchronization of the movement of the first driven block 140 and the second driven block 150 and enhancing the working stability and reliability of the clamping mechanism 100.

[0075] The driving end of the third driving member 230 is connected to the fixed end of the second driving member 220, and the second driving member 220 is connected to the reamer 210. In this way, the third driving member 230 can drive the second driving member 220 and the reamer 210 to move toward or away from the clamping mechanism 100, so that the reamer 210 can extend into the gun head 400 to clean the inside of the gun head 400 and move out of the gun head 400 after the cleaning is completed.

[0076] In some alternative embodiments, such as Figures 7 to 9 shown, the blade of the reamer 210 is a hollow spiral shape.

[0077] In this embodiment, the blade of the reamer 210 is a hollow spiral shape. In this way, during the rotation of the reamer 210, the cutting and cleaning ability of the reamer 210 can be improved, which facilitates the gradual extension of the reamer 210 into the gun head 400 and enhances the cleaning efficiency. The inside of the blade is hollow, so that the debris generated during the cleaning process can be collected in the hollow part of the blade, reducing the accumulation of debris on the blade to interfere with the cleaning effect and the occurrence of the situation where the cleaned debris falls randomly, and improving the environmental cleanliness during the use of the cleaning device. Moreover, the debris in the blade can be blown out by the gas blown by the air jet member 310 to be collected in the receiving box 320, further improving the environmental cleanliness during the use of the cleaning device and reducing the pollution of the debris to the surrounding environment and equipment.

[0078] In some alternative embodiments, such as Figure 7 and Figure 8 shown, the cleaning mechanism 200 further includes a mounting plate 240. The mounting plate 240 is connected to the driving end of the third driving member 230. The fixed end of the second driving member 220 is provided on one side wall of the mounting plate 240. The driving end of the second driving member 220 passes through the mounting plate 240 and is connected to a reamer 210 located on the other side wall of the driving member. The air jet member 310 is provided on the other side wall of the mounting plate 240.

[0079] In this embodiment, the mounting plate 240 is connected to the driving end of the third driving member 230. The fixed end of the second driving member 220 is provided on one side wall of the mounting plate 240. The third driving member 230 drives the mounting plate 240 to move. The second driving member 220 is provided on the mounting plate 240. The fixed end of the second driving member 220 is connected to the driving end of the third driving member 230 through the mounting plate 240. The mounting plate 240 can provide stable support for the second driving member 220, facilitating the connection between the second driving member 220 and the third driving member 230.

[0080] The fixed end of the second driving member 220 is provided on one side wall of the mounting plate 240. The driving end of the second driving member 220 passes through the mounting plate 240 and is connected to a reamer 210 located on the other side wall of the mounting plate 240. The reamer 210 can extend into the gun head 400. That is to say, the fixed end of the second driving member 220 is located on the side wall of the mounting plate 240 facing away from the clamping mechanism 100. The driving end of the second driving member 220 passes through the mounting plate 240 and is located on the side wall of the mounting plate 240 facing the clamping mechanism 100. The connection point between the fixed end and the driving end of the second driving member 220 is located on the side wall of the mounting plate 240 facing away from the clamping mechanism 100, and the air jet member 310 is provided on the side wall of the mounting plate 240 facing the clamping mechanism 100. When the debris falling from the reamer 210 is not blown away in time, the debris can fall on the mounting plate 240. The gas blown out by the air jet member 310 diffuses when it blows to the reamer 210 and blows towards the mounting plate 240, and can blow the debris on the mounting plate 240 into the material receiving box 320, so as to reduce the situation that the debris falls on the connection point between the fixed end and the driving end of the second driving member 220, causing wear and damage to the second driving member 220, and improving the service life of the cleaning mechanism 200.

[0081] In some alternative embodiments, such as Figure 7 and Figure 8 shown, the cleaning mechanism 200 further includes a fixing plate 250 and a limiting rod 260. The fixing plate 250 is connected to the fixed end of the third driving member 230. One end of the limiting rod 260 is fixedly connected to the fixing plate 250, and the other end of the limiting rod 260 is slidably connected to the mounting plate 240 to limit the movement direction of the mounting plate 240.

[0082] In this embodiment, the limiting rod 260 can limit the movement direction of the mounting plate 240 by having one end of the limiting rod 260 fixedly connected to the fixing plate 250 and the other end of the limiting rod 260 slidably connected to the mounting plate 240. The limiting rod 260 allows the mounting plate 240 to move only along a predetermined track during the cleaning process, thereby reducing the deviation or shaking of the mounting plate 240 and improving the stability and control accuracy during the cleaning process.
