Description

Technical Field

[0001] The utility model belongs to the technical field of welding machine cooling devices, and particularly relates to a supporting cooling system for a can-making welding machine. Background Art

[0002] As the name implies, an iron can is a can made of iron. Existing iron cans are mainly welded by welding. During the welding process of iron cans, in order to ensure the normal operation of the welding machine, a supporting cooling system is generally required to cool down the mercury-free welding wheel and the welding arm of the welding machine.

[0003] The existing cooling system for welding machines mainly places cooling coils in a cooling tank, then injects emulsion into the cooling tank, and then the relatively low-temperature cooling water provided by a refrigerating machine (equipped separately) passes through the copper coils (the first loop) in the cooling tank to exchange heat with the emulsion in the cooling tank, thereby realizing the cooling of the emulsion. Finally, the emulsion is pumped out by a water pump (the second loop) for cooling the welding arm and the mercury-free welding wheel of the welding machine.

[0004] Although the existing cooling system can play a certain cooling effect on the welding arm and the mercury-free welding wheel of the welding machine, since there is no stirring device in the cooling tank, the emulsion in the cooling tank cannot exchange heat well with the cooling water in the cooling coils, resulting in a low cooling efficiency of the cooling water passing through the cooling coils to cool the emulsion.

[0005] Therefore, it is necessary to invent a supporting cooling system for a can-making welding machine to solve the above problems. Summary of the Utility Model

Two limiting rods are vertically and slidably inserted through the top of the flow stirring plate. The limiting rods are vertically and fixedly connected to the inner wall of the bottom of the cooling tank, and the two limiting rods are symmetrical about the reciprocating lead screw.

[0009] Further, filter boxes are detachably installed at the bottom positions where both sides of the flow stirring plate are deflected downward. Through holes are formed through the positions on the top of the flow stirring plate corresponding to the top openings of the filter boxes. A floating plate is arranged in the through holes.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0026] The present utility model provides as Figures 1 to 6A supporting cooling system for a can-making welding machine is shown, including a cooling box 1. A liquid inlet pipe 2 is connected to the front side of the cooling box 1. A box cover 3 is arranged on the top of the cooling box 1. A water pump 4 is installed on the top of the box cover 3. One end of the water pump 4 is connected to a connector 5, and the other end of the water pump 4 is connected to a water suction pipe 6. The water suction pipe 6 is inserted through the box cover 3 and located in the cooling box 1. A plurality of cooling coils 7 are vertically and parallelly arranged in the cooling box 1, and the two ends of adjacent two cooling coils 7 are connected in series in turn. The free ends of the two cooling coils 7 on both sides penetrate and are inserted into the rear side of the cooling box 1. A stirring component 8 is arranged between adjacent two cooling coils 7. A controller 9 is installed on the top of the box cover 3. The controller 9 is electrically connected to the water pump 4. A return pipe 15 is connected to one side of the cooling box 1 close to the connector 5.

[0027] Before using the present utility model to cool the mercury-free welding wheel and welding arm of the welding machine, first inject the emulsion into the cooling box 1 through the inlet pipe, and make the emulsion submerge the cooling coils 7. Then connect the free ends of the two cooling coils 7 on both sides to the refrigerator to form a loop. Finally, connect the connector 5 of the water pump 4 and the return pipe 15 on the side of the cooling box 1 to the cooling pipeline of the welding machine to form a loop.

[0028] When the present utility model cools the mercury-free welding wheel and welding arm of the welding machine, the controller 9 can control the water pump 4 to pump the emulsion in the cooling box 1 into the cooling pipeline of the welding machine to cool the mercury-free welding wheel and welding arm. Then the emulsion that has absorbed heat can flow back to the cooling box 1 through the return pipe 15. Finally, the emulsion in the cooling box 1 can exchange heat with the cooling water inside through the cooling coils 7, so as to realize the cooling operation of the emulsion. Then the cooled emulsion can repeat the above operation to cool the mercury-free welding wheel and welding arm of the welding machine in a cycle.

[0029] In addition, by setting the stirring component 8, during the heat exchange process between the emulsion and the cooling water in the cooling coils 7, the stirring component 8 can stir the emulsion, thereby increasing the contact speed between the emulsion and the cooling coils 7, and further improving the heat exchange efficiency between the cooling water and the emulsion in the cooling coils 7.

[0030] Such as Figures 2 to 6As shown, the stirring assembly 8 includes a stirring plate 81. The length direction of the stirring plate 81 is parallel to the side surface of the cooling tank 1, and both sides of the stirring plate 81 are deflected downward. A reciprocating lead screw 82 is vertically and threadedly inserted through the middle position at the top of the stirring plate 81. The bottom end of the reciprocating lead screw 82 is rotatably connected to the bottom inner wall of the cooling tank 1. The top end of the reciprocating lead screw 82 rotatably penetrates and is inserted into the box cover 3. A transmission belt 83 is connected between the top ends of multiple reciprocating lead screws 82, and a motor 84 is connected to the top end of one of the reciprocating lead screws 82. Two limiting rods 85 are vertically and slidably inserted through the top of the stirring plate 81. The limiting rods 85 are vertically and fixedly connected to the bottom inner wall of the cooling tank 1, and the two limiting rods 85 are symmetrical about the reciprocating lead screw 82;

[0031] During the process of the mercury-free welding wheels and welding arms of the emulsifying liquid welder in the cooling tank 1 being cooled, the motor 84 can be started, so that multiple reciprocating lead screws 82 can rotate under the drive of the transmission belt 83 or the motor 84. As the reciprocating lead screw 82 rotates, the reciprocating lead screw 82 can cooperate with the limiting rod 85 to drive the stirring plate 81 to move in the vertical direction, so that the emulsifying liquid in the cooling tank 1 can contact the cooling coil 7 faster under the agitation of the stirring plate 81, thereby improving the heat exchange efficiency between the cooling water and the emulsifying liquid in the cooling coil 7.

[0032] As Figure 5 As shown, filter boxes 10 are detachably installed at the bottom positions where both sides of the stirring plate 81 are deflected downward. Through holes are formed through the positions at the top of the stirring plate 81 corresponding to the top openings of the filter boxes 10. A floating plate 11 is arranged in the through holes. One side of the floating plate 11 close to the reciprocating lead screw 82 is hinged to the inner wall on the corresponding side of the through hole. The size of the floating plate 11 matches the size of the through hole, and the floating plate 11 can only deflect downward. In the initial state, the top surface of the floating plate 11 is flush with the top surface of the stirring plate 81, and the buoyancy of the floating plate 11 is greater than its own gravity. The moving height of the stirring plate 81 in the vertical direction matches the height of the cooling coil 7, and multiple stirring plates 81 are evenly distributed in the cooling tank 1;

[0033] Since both sides of the stirring plate 81 are deflected downward, when the stirring plate 81 moves upward, the stirring plate 81 can stir the emulsifying liquid in the cooling tank 1 onto the adjacent two cooling coils 7, thereby increasing the contact speed between the emulsifying liquid and the cooling coil 7, and further improving the heat exchange efficiency between the emulsifying liquid and the cooling water in the cooling coil 7;

[0034] By providing a filter box 10, during the upward movement of the turbulence plate 81, the emulsion can flow downward along the top surface of the turbulence plate 81. During this process, the floating plate 11 can deflect downward under the impact of the emulsion, so that the through-hole can be partially opened. Subsequently, the impurities in the emulsion can enter the filter box 10 through the gap opened by the through-hole and be intercepted and filtered, thereby avoiding the attachment of impurities in the emulsion to the surface of the cooling coil 7 during long-term use, and further affecting the heat exchange efficiency between the cooling water in the cooling coil 7 and the emulsion;

[0035] During the downward movement of the turbulence plate 81, the floating plate 11 can always close the through-hole under the action of buoyancy, thereby preventing the impurities filtered out by the filter box 10 from flowing back into the emulsion in the cooling tank 1 through the through-hole.

[0036] As Figure 5 and Figure 6 shown, both sides of the turbulence plate 81 are close to the corresponding side of the cooling coil 7. Soft brush strips 12 are evenly installed on both sides of the turbulence plate 81, and the soft brush strips 12 can contact the corresponding side of the cooling coil 7;

[0037] By providing the soft brush strips 12, during the up and down movement of the turbulence plate 81, the soft brush strips 12 can gently sweep across the top of the cooling coil 7, thereby avoiding the attachment of impurities in the emulsion to the surface of the cooling coil 7, and further ensuring the cleanliness of the surface of the cooling coil 7, and avoiding the influence of the fouled surface of the cooling coil 7 on the heat exchange efficiency between the emulsion and the cooling water passing through the cooling coil 7.

[0038] As Figures 1 to 3 shown, universal wheels 13 are installed at the four corners of the bottom of the cooling tank 1, and the universal wheels 13 have a self-locking function; two handles 14 are installed on the top of the tank cover 3, and the two handles 14 are symmetrically distributed at positions near both sides of the top of the tank cover 3;

[0039] By providing the handles 14, the tank cover 3 can be easily opened through the handles 14, and at the same time, it is also convenient to push the cooling tank 1 through the handles 14, so that the cooling tank 1 moves to the designated position under the support and movement of the universal wheels 13, and then the position of the cooling tank 1 can be fixed through the self-locking function of the universal wheels 13.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
