Description

Technical Field

[0001] The present invention relates to the technical field of refrigerator condenser pipes, and particularly to an automatic chip-removing and zinc-removing machine for the zinc coating on the surface of a refrigerator condenser pipe. Background Art

[0002] The function of a refrigerator condenser is to dissipate heat to the surrounding air. The condenser in the refrigerator refrigeration system pipeline dissipates the heat in the high-temperature and high-pressure gaseous refrigerant to the surrounding air, so as to liquefy the refrigerant into a medium-temperature and high-pressure liquid refrigerant. That is to say, the condenser is a key heat exchange component of the refrigeration system, and the condenser pipe is mainly used for the connection of the condenser to play a conveying role. Most of the heat dissipation pipes used in general refrigerator condensers are "Bundy pipes", that is, galvanized steel pipes. The production of the condenser requires many steps, and the overall production process is relatively complex. Removing the zinc coating on the surface of the refrigerator condenser pipe is one of the processes. Only after removing the surface zinc coating can the next welding process be carried out. When removing the zinc coating on the surface of the galvanized steel pipe, most of the operators manually wipe the steel pipe to remove it, which is not only laborious, but also the number of steel pipes that the operator can clean at one time is small, which is rather inconvenient. Summary of the Invention

[0003] In order to overcome the above technical problems, the purpose of the present invention is to provide an automatic chip-removing and zinc-removing machine for the zinc coating on the surface of a refrigerator condenser pipe. By placing a plurality of condenser pipes inside a rectangular pipe to automatically enter the gap between two adjacent grinding mechanisms, starting an air pump to make the plurality of grinding mechanisms closely adhere to the condenser pipes, and starting a moving mechanism and a rotating mechanism to drive the plurality of grinding mechanisms to rotate while reciprocatingly moving and rubbing the condenser pipes, and using a fixing mechanism and a pressing mechanism to fix and move the position of the condenser pipes so that they are fully ground, thus facilitating the operator to grind a plurality of condenser pipes simultaneously. After grinding, start the moving mechanism and the rotating mechanism to deform the plurality of grinding mechanisms, so that the chips that may adhere to the grinding mechanisms fall off, thus facilitating the operator to collect and clean the chips.

[0004] The purpose of the present invention can be realized by the following technical solutions:

[0005] An automatic chip-removing and zinc-removing machine for the zinc coating on the surface of a refrigerator condenser pipe, comprising a base, both opposite sides of the top surface of the base are fixedly connected with connecting frames, and the centers of the adjacent sides of the two connecting frames are both fixedly connected with rectangular rods. A rectangular pipe is arranged between the two connecting frames, and a frame body is arranged at the bottom of the rectangular pipe. A pressing mechanism is arranged on the top surface of the frame body, and a plurality of grinding mechanisms are arranged inside the frame body. Six grinding mechanisms are provided with a moving mechanism and a rotating mechanism, and a fixing mechanism is arranged inside the rectangular pipe;

[0006] The grinding mechanism includes a U-shaped plate. Circular plates are rotatably connected to the two opposite inner side walls of the U-shaped plate. A rubber tube is fixedly connected between the two circular plates. A grinding wire mesh is fixedly sleeved on the outer side wall of the rubber tube. Fixed rods are fixedly connected to the opposite sides of the two circular plates. One end of each of the two fixed rods penetrates through the inner side wall of the adjacent U-shaped plate and is rotatably sleeved with the inner side wall of the adjacent U-shaped plate. Among them, a ventilation hole communicating with the inside of the rubber tube is opened at one end of one of the fixed rods. A conduit is rotatably sleeved in the ventilation hole. The conduit is provided with an air pump in a matching manner, and the inside of the conduit is connected to the inside of the air outlet end of the air pump. By inserting the air-conditioning condensate pipe into the gap between two adjacent U-shaped plates on two adjacent grinding mechanisms, an external air pump is provided, and the air outlet end of the air pump is connected to the inside of multiple conduits through connectors such as multi-way valves. When the air pump injects air into multiple conduits, the rubber tubes on multiple grinding mechanisms can be inflated under the influence of the air injection of the air pump, so that the condensate pipe that could originally be easily inserted into the gap between two adjacent U-shaped plates is clamped by two adjacent inflated rubber tubes, and the grinding wire mesh is closely attached to the surface of the condensate pipe, thereby using the grinding wire mesh to grind the surface of the condensate pipe. The grinding wire mesh is a wire mesh woven from a metal material, which can scrape and remove the coating on the surface of the condensate pipe. Moreover, after use, the air pump can be started to pump air from multiple rubber tubes, so that multiple rubber tubes deflate and drive the adjacent grinding wire meshes to contract and change their shapes, making the coating debris adhered to the grinding wire meshes fall off the grinding wire meshes easily due to the shape change of the grinding wire meshes.

[0007] Furthermore: Communication holes are opened at the centers of the top and bottom surfaces of the frame body. The inner side wall of the communication hole on the top surface of the frame body is fixedly connected to the bottom end of the rectangular pipe, and the inner side wall of the communication hole on the bottom surface of the frame body is fixedly connected with a connecting pipe. Rectangular sleeves are fixedly connected to the opposite sides of the rectangular pipe. One ends of two rectangular rods are respectively slidably sleeved in the two rectangular sleeves. A retaining rod is fixedly connected between the two opposite inner side walls of the rectangular pipe. Multiple grinding mechanisms are respectively located on the opposite sides of the retaining rod and are evenly arranged. Sliding insertion holes are opened at the top ends of the opposite sides of the connecting pipe, and an insertion plate is movably inserted between the two sliding insertion holes;

[0008] Limit through holes penetrating through the other end are opened at one ends of the U-shaped plates on multiple grinding mechanisms. Slide rails are slidably sleeved in multiple limit through holes. Connecting arms are fixedly connected to both ends of multiple slide rails. The adjacent ends of the connecting arms at both ends of the same slide rail are respectively fixedly connected to the top of the opposite sides of the frame body. There is a certain distance between one end of the rectangular rod and the adjacent rectangular sleeve, so that the rectangular pipe can have a certain sliding space on the two rectangular rods through the two rectangular sleeves. Multiple grinding mechanisms are all connected to the frame body through slide rails to limit multiple U-shaped plates, so that the top surfaces of multiple U-shaped plates face upward, facilitating the condensate pipe to enter the gap between the U-shaped plates.

[0009] Furthermore, the moving mechanism includes a first C-shaped plate and a second C-shaped plate, and the first C-shaped plate and the second C-shaped plate are respectively located on opposite sides of the frame body. A plurality of jacks are provided on one side of each of the first C-shaped plate and the second C-shaped plate. The plurality of jacks correspond to a plurality of grinding mechanisms one by one. The plurality of grinding mechanisms are staggeredly and fixedly connected inside the jacks on the first C-shaped plate and the second C-shaped plate. Two U-shaped frames are fixedly connected to the bottom of opposite sides of the frame body, and guide wheels are rotatably connected between one ends of the two arms of the four U-shaped frames. A transmission belt is rotatably sleeved between the outer side walls of two guide wheels that are respectively located on opposite sides of the frame body and are parallel. The bottom surface of the first C-shaped plate is fixedly connected to the top surface of the two transmission belts, and the inner bottom surface of the second C-shaped plate is fixedly connected to the bottom surface of the two transmission belts. A second electric push rod is fixedly connected to the outer side wall of the connecting pipe, and the movable end of the second electric push rod is fixedly connected to the bottom surface of the second C-shaped plate. The number of the plurality of grinding mechanisms is an even number, so that the plurality of grinding mechanisms can be evenly dispersed on opposite sides of the gear lever, and the number of grinding mechanisms on opposite sides of the gear lever is the same. And among any two adjacent grinding mechanisms, the placement directions of the two grinding mechanisms are the same. The outer side wall of a fixing rod on one U-shaped plate is rotatably connected to the inner side wall of the corresponding jack on the first C-shaped plate, and the other fixing rod is movably inserted into the corresponding jack on the second C-shaped plate. The outer side wall of a fixing rod on the other U-shaped plate is rotatably connected to the inner side wall of the corresponding jack on the second C-shaped plate, and the other fixing rod is movably inserted into the corresponding jack on the first C-shaped plate. Place a plurality of condenser tubes into the top opening of the rectangular tube, and insert the insertion plate into the two sliding insertion holes to limit the condenser tubes, so that the condenser tubes automatically fall into the gap between two adjacent U-shaped plates. Then take out the insertion plate and start the pressing mechanism to control the movement of the plurality of condenser tubes, so that the condenser tubes automatically fall into the gap between two adjacent U-shaped plates. When starting the second electric push rod and making its movable end do reciprocating telescopic motion, the two transmission belts can be pulled by the second C-shaped plate to rotate reciprocally, thereby simultaneously driving the first C-shaped plate and the second C-shaped plate to move towards each other or away from each other. At this time, since any two adjacent U-shaped plates are driven by the first C-shaped plate and the second C-shaped plate respectively, the moving directions of any two adjacent U-shaped plates are opposite, so that any two adjacent U-shaped plates can rub and rotate the condenser tubes between the two adjacent U-shaped plates through the grinding wire mesh, so that the surface of the condenser tube rotates to increase the contact surface with the grinding wire mesh, and the condenser tube contacts and is polished by the grinding wire mesh more comprehensively, so that a plurality of condenser tubes can be polished simultaneously and the polishing effect can be improved.

[0010] Furthermore, the top surface of the gear lever and the top surfaces of multiple U-shaped plates are all arc-shaped surfaces. The highest points of the arc surfaces of the U-shaped plates on the two grinding mechanisms located at both ends among the multiple grinding mechanisms are respectively located below the opposite sides of the rectangular pipe. Moreover, the top surfaces of multiple U-shaped plates are all in contact with the inner top surface of the frame. When multiple condenser pipes fall onto the top surface of the gear lever and the top surfaces of the U-shaped plates, they will automatically slide down along their arc surfaces into the gaps between the two U-shaped plates. When the bottom ends of the condenser pipes reach the side walls of the rectangular pipe, they can automatically slide down along the arc surfaces of the U-shaped plates at the ends into the gaps between two adjacent U-shaped plates, making it not easy for the condenser pipes to get stuck inside the frame and not come out from the connecting pipe. Additionally, the highest points of the arc surfaces of the two U-shaped plates located on both sides of the gear lever and closest to the gear lever are respectively located below the opposite sides of the gear lever, enabling the bottom ends of the condenser pipes in all rectangular pipes to slide into the gaps between two adjacent U-shaped plates and not easily fall to other positions.

[0011] Furthermore, the rotation mechanism includes two arc-shaped frames, and the bottom surfaces of both arc-shaped frames are fixedly connected to the top surface of the frame body. A ring body is rotatably sleeved between the two arc-shaped frames, and the rectangular pipe is located inside the ring body. Two square pipes are fixedly connected to the outer side wall of the ring body, and sliding plates are slidably sleeved inside both square pipes. One end of each of the two sliding plates is fixedly connected to a guide rod. Guide grooves are formed in the inner top surfaces of the first C-shaped plate and the second C-shaped plate, and toothed plates are slidably connected inside both guide grooves. Moving grooves whose interiors are connected to the interiors of the adjacent guide grooves are formed in the top surfaces of the first C-shaped plate and the second C-shaped plate, and one end of each of the two guide rods respectively penetrates through the two moving grooves. One end of each of the two guide rods is rotatably connected to the top surface of the adjacent toothed plate. A control motor is fixedly connected to the bottom surface of the frame body, and the motor shaft of the control motor penetrates through the top surface of the frame body and is fixedly sleeved with a rubbing wheel. The outer side wall of the rubbing wheel is in contact with the inner side wall of the ring body. Gear rings are fixedly sleeved on the outer side walls of the two fixed rods located on the same grinding mechanism, and the gear rings are meshed with the adjacent toothed plates. By starting the control motor to drive the rubbing wheel to rotate reciprocally, the ring body rotates reciprocally. The ring body drives the square pipes and the adjacent sliding plates to rotate reciprocally, so that the two sliding plates pull the adjacent toothed plates to move reciprocally through the adjacent guide rods. Moreover, the moving directions of the two toothed plates are opposite. When multiple rubber pipes are inflated by the air pump, the movable end of the second electric push rod reciprocally extends and retracts within a certain range, so that the fixed rod on the U-shaped plate connected to the first C-shaped plate does not insert into the jack on the second C-shaped plate and does not contact the toothed plate on the second C-shaped plate, and the fixed rod on the U-shaped plate connected to the second C-shaped plate does not insert into the jack on the first C-shaped plate and does not contact the toothed plate on the first C-shaped plate. Since there is gas inside the rubber pipes on multiple grinding mechanisms, they are in an inflated state and reach their elastic limit, so that the rubber pipes can drive the two connected circular plates to rotate synchronously. The rubber pipes on the multiple U-shaped plates connected to the first C-shaped plate and the rubber pipes on the multiple U-shaped plates connected to the second C-shaped plate rotate because the gear rings connected to the end fixed rods are driven by the adjacent toothed plates, so that all the grinding wire meshes rotate while rubbing the condensate pipe to rotate, thereby polishing the surface of the condensate pipe, and thus improving the polishing effect. Then, after the polishing is completed, the air pump sucks out the air inside all the rubber pipes, causing the multiple rubber pipes to shrink. At this time, the rubber pipes have sufficient elastic limit to undergo elastic deformation. Then the second electric push rod is started, so that the fixed rod on the U-shaped plate connected to the second C-shaped plate inserts into the jack on the first C-shaped plate, and the fixed rod on the U-shaped plate on the first C-shaped plate inserts into the second C-shaped plate, so that the gear rings on the two fixed rods at both ends of the same U-shaped plate respectively contact the two toothed plates. Thus, when the ring body rotates reciprocally, the two toothed plates drive the two circular plates on the same U-shaped plate to rotate reciprocally, and the rotation directions of these two circular plates are opposite when they rotate, so that the shrunken rubber pipes on all the U-shaped plates are twisted by the reciprocal rotation of the adjacent two circular plates and drive the connected grinding wire meshes to twist synchronously, facilitating the detachment of debris from the grinding wire meshes.

[0012] The fixing mechanism further comprises two clamping plates, rectangular sliding holes are provided on opposite sides of the rectangular tube, and the two clamping plates are respectively slidably connected to the inside of the two rectangular sliding holes, one end of the two clamping plates are rotatably connected to a connecting rod, the top surface of the frame is fixedly connected to a first electric push rod, and the movable end of the first electric push rod is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to a rotating shaft, and one end of the two connecting rods are rotatably connected to the outer side wall of the rotating shaft, because the bottom of the condensation tube falls between two adjacent U-shaped plates, when the first electric push rod is started, the movable end of the first electric push rod By driving the two clamps to move toward each other through the two connecting rods, the two clamps will clamp the other parts of all the condenser tubes in the rectangular tube and make the condenser tubes in an inclined state, thereby increasing the contact force between the surface of the condenser tube and the polishing screen and fixing the positions of multiple condenser tubes. They are not easily driven by the rotation of the polishing screen or automatically slide down due to their own weight and move out along the connecting tube. The positions of the condenser tubes can be fixed by the two clamps, thereby increasing the polishing time. In addition, when the user throws multiple condenser tubes from the top of the rectangular tube, he only needs to keep the multiple condenser tubes in a vertical state, which is convenient for the user to throw the condenser tubes.

[0013] Furthermore, two guide plates are fixedly connected on opposite sides of the rectangular tube, and the two guide plates located on the same side of the rectangular tube are respectively located at the top and bottom ends of adjacent clamps. The guide plates are used to limit the clamps to prevent the clamps from tilting or falling out of the rectangular sliding holes after being driven by the first electric push rod to leave the rectangular tube.

[0014] The invention further comprises: the pressing mechanism comprises a rotating rod, and the bottom end of the rotating rod is rotatably connected to the top surface of the frame, the top of the rotating rod is fixedly connected to a connecting plate, and the top surface of the connecting plate is fixedly connected to two supporting arms, and a winch is rotatably connected between the tops of the two supporting arms, the top surface of the connecting plate is fixedly connected to a driving motor, and the motor shaft of the driving motor passes through a supporting arm and is fixedly connected to the center of one side of the winch, a pressing plate is arranged under the winch, and the pressing plate is slidably embedded in the inside of the rectangular tube, a pull rope is fixedly connected to the center of the top surface of the pressing plate, and one end of the pull rope is fixedly wound around the outer wall of the winch, before use, when it is necessary to insert the condenser tube from the top of the rectangular tube, the rotating rod is rotated to make the pressing plate detach from the top of the rectangular tube, so that the user can insert the condenser tube, and then after the condenser tube is inserted, the rotating rod is reset, and the driving motor is started to drive the winch to rotate, so that the winch lowers the pull rope, so that the pressing plate is embedded in the inside of the rectangular tube to slide and press the top of the condenser tube to control the falling of the condenser tube.

[0015] Furthermore, a magnetic layer is fixedly connected to the bottom surface of the pressing plate, and the condenser is generally a galvanized steel tube. The top of the condenser is adsorbed by the magnetic layer, and the movement of the condenser in the rectangular tube can be further controlled by the pressing plate, and when the pressing plate is close to the two clamping plates, the first electric push rod can be started to drive the two clamping plates to clamp toward each other, and the adjacent ends of the clamping plates are chamfered structures, which makes it easy for the tops of multiple condenser tubes to separate from the magnetic layer when the two clamping plates clamp toward each other.

[0016] Furthermore, a collection groove is provided at the center of the top surface of the base, and a slot is provided at the center of the inner bottom surface of the collection groove. One side of the rectangular pipe is fixedly connected with a vibration motor. The vibration motor vibrates the rectangular pipe and the frame body, which is convenient for when the condenser tube is put in, so that the condenser tube slides along the arc surfaces of the baffle rod and the U-shaped plate due to vibration and falls into the gap between two adjacent U-shaped plates. It is convenient for the debris adhered to multiple grinding mechanisms in the frame body to fall into the collection groove and the slot. After the pressing plate moves to the clamping plate, only the end of the condenser tube remains unground. Then the condenser tube is clamped by two adjacent rubber tubes. The driving motor is started to drive the winch to pull back the pressing plate to separate it from the condenser tube. Then the condenser tube falls into the slot from the connecting pipe after being ground and separated from the rubber tube due to its own weight and the rotation of the rubber tube. Then the user takes out multiple condenser tubes. If there is any omission in the top end of the condenser tube and it is not completely ground, the user can manually grind the coating on the top end part of the condenser tube to remove it.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By putting multiple condenser tubes into the rectangular pipe from the top opening of the rectangular pipe, multiple condenser tubes automatically slide into the gap between two adjacent grinding mechanisms. Then the air pump is started to make multiple grinding mechanisms closely adhere to the condenser tubes. The moving mechanism and the rotating mechanism are started to drive multiple grinding mechanisms to rotate while reciprocatingly moving and rubbing the condenser tubes, so as to grind the condenser tubes. The fixing mechanism can be used to fix the position of the condenser tubes to allow the condenser tubes to be fully ground. The pressing mechanism is used to control the downward movement position of the condenser tubes, so as to facilitate the user to grind multiple condenser tubes at the same time. After grinding is completed, the moving mechanism and the rotating mechanism are started to deform multiple grinding mechanisms, so that the debris that may adhere to the grinding mechanisms falls, which is convenient for the user to collect and clean the debris;

[0019] 2. By putting multiple condenser tubes into the rectangular pipe and starting the vibration motor to drive the rectangular pipe to vibrate, the bottom ends of multiple condenser tubes automatically slide along the arc surfaces of the baffle rod and the U-shaped plate due to vibration and are embedded into the gap between two adjacent U-shaped plates. Then the air pump is started to make multiple rubber tubes expand to clamp the condenser tubes in the gap, so that the grinding wire meshes on the rubber tubes closely adhere to the surface of the condenser tubes. Then when the second electric push rod is started and its movable end makes a reciprocating telescopic movement, the two transmission belts can be pulled to reciprocatingly rotate through the second U-shaped plate, so as to drive the first U-shaped plate and the second U-shaped plate to move towards each other or away from each other at the same time. Since any two adjacent U-shaped plates are driven by the first U-shaped plate and the second U-shaped plate respectively, the moving directions of any two adjacent U-shaped plates are opposite, so that any two adjacent U-shaped plates can rub the condenser tubes between the two adjacent U-shaped plates to rotate through the grinding wire meshes, so that the contact surface between the condenser tube surface and the grinding wire meshes is increased through rotation, and the condenser tubes can contact and be ground by the grinding wire meshes more comprehensively, so that multiple condenser tubes can be ground at the same time and the grinding effect can be improved;

[0020] 3. When multiple rubber tubes are inflated by the air pump, the movable end of the second electric push rod reciprocates and stretches within a certain range, so that the gear on the U-shaped plate connected to the first C-shaped plate does not contact the toothed plate on the second C-shaped plate, and the U-shaped plate connected to the second C-shaped plate does not contact the toothed plate on the first C-shaped plate. Then, the control motor is started to drive the rubbing wheel to rotate reciprocally, so that the ring body rotates reciprocally. The ring body drives the square tube and the adjacent slide plate to rotate reciprocally, so that the two slide plates drive the adjacent toothed plate to reciprocate through the adjacent guide rods, so that the rubber tubes on multiple grinding mechanisms drive the two connected circular plates to rotate synchronously, so that the rubber tubes on the multiple U-shaped plates connected to the first C-shaped plate and the rubber tubes on the multiple U-shaped plates connected to the second C-shaped plate rotate because the gears connected to the end fixing rods are driven by the adjacent toothed plates, so that all the grinding wire meshes rotate themselves while rubbing the condensing tube to rotate, so as to polish the surface of the condensing tube, thereby improving the polishing effect. After the outer wall of a section of the condensing tube is polished, the driving motor is started to drive the winch to lower the pulling rope so that the pressing plate presses the tops of multiple condensing tubes to move them downward. Then, the first electric push rod is started, so that the connecting block drives the two clamping plates to clamp the outer walls of multiple condensing tubes through two connecting rods, so that multiple condensing tubes are inclined to fix their positions, and then the outer walls are polished by using the grinding wire mesh;

[0021] 4. After the polishing is completed, the air pump sucks the air inside all the rubber tubes, so that multiple rubber tubes are deflated, and multiple rubber tubes drive the adjacent grinding wire meshes to contract and deform, which is convenient for the debris to break away from the grinding wire mesh. At the same time, the vibration motor is started, and the vibration is used to facilitate the debris to break away from the grinding wire mesh. At this time, the rubber tubes have enough elastic limit to perform elastic deformation. Then, the second electric push rod is started, so that the fixing rod on the U-shaped plate connected to the second C-shaped plate is inserted into the jack on the first C-shaped plate, and the fixing rod on the U-shaped plate on the first C-shaped plate is inserted into the second C-shaped plate, so that the gears on the two fixing rods at both ends of the same U-shaped plate are respectively in contact with the two toothed plates. Thus, when the ring body rotates reciprocally, the two toothed plates drive the two circular plates on the same U-shaped plate to rotate reciprocally, and the rotation directions of these two circular plates are opposite when they rotate, so that the deflated rubber tubes on all the U-shaped plates are twisted by the reciprocal rotation of the adjacent two circular plates and drive the connected grinding wire meshes to twist synchronously, which is convenient for the debris to break away from the grinding wire mesh.

Detailed implementation manners

[0033] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-9 As shown, an automatic chip and zinc removing machine for the galvanized layer on the surface of a refrigerator condenser tube includes a base 100. On both opposite sides of the top surface of the base 100, connecting frames 110 are fixedly connected. And at the center of the adjacent sides of the two connecting frames 110, rectangular rods 120 are fixedly connected. A rectangular tube 200 is arranged between the two connecting frames 110. And at the bottom of the rectangular tube 200, a frame body 230 is arranged. On the top surface of the frame body 230, a pressing mechanism 300 is arranged. And inside the frame body 230, a plurality of grinding mechanisms 500 are arranged. The six grinding mechanisms 500 are equipped with a moving mechanism 600 and a rotating mechanism 700. Inside the rectangular tube 200, a fixing mechanism 400 is arranged;

[0035] The grinding mechanism 500 includes a U-shaped plate 510. On both opposite inner side walls of the U-shaped plate 510, circular plates 530 are rotatably connected. And between the two circular plates 530, a rubber tube 560 is fixedly connected. On the outer side wall of the rubber tube 560, a grinding wire mesh 561 is fixedly sleeved. On the opposite sides of the two circular plates 530, fixing rods 540 are fixedly connected. And one end of each of the two fixing rods 540 penetrates through the adjacent inner side wall of the U-shaped plate 510 and is rotatably sleeved with the adjacent inner side wall of the U-shaped plate 510. Among them, a ventilation hole 541 communicating with the inside of the rubber tube 560 is opened at one end of one fixing rod 540. Inside the ventilation hole 541, a conduit 542 is rotatably sleeved. The conduit 542 is equipped with an air pump. And the inside of the conduit 542 is connected to the inside of the air outlet end of the air pump. By inserting the air conditioner condenser tube into the gap between the two U-shaped plates 510 on two adjacent grinding mechanisms 500, and externally providing an air pump, and connecting the air outlet end of the air pump to the inside of a plurality of conduits 542 through connectors such as multi-way valves. When the air pump injects air into the plurality of conduits 542, the rubber tubes 560 on the plurality of grinding mechanisms 500 can be inflated under the influence of the air injection of the air pump. The condenser tube that could originally be easily inserted into the gap between the two adjacent U-shaped plates 510 is clamped by the two adjacent inflated rubber tubes 560. And the grinding wire mesh 561 is closely attached to the surface of the condenser tube. Thus, the surface of the condenser tube is ground by the grinding wire mesh 561. The grinding wire mesh 561 is a wire mesh woven from a metal material, which can scrape and remove the coating on the surface of the condenser tube. And after use, the air pump can be started to pump air out of the plurality of rubber tubes 560, so that the plurality of rubber tubes 560 shrink and drive the adjacent grinding wire meshes 561 to contract and change their shapes. The coating debris adhered to the grinding wire mesh 561 is facilitated to fall off from the grinding wire mesh 561 due to the shape change of the grinding wire mesh 561.

And the plurality of grinding mechanisms 500 are all connected to the frame body 230 through the slide rails 520 to limit the plurality of U-shaped plates 510, so that the top surfaces of the plurality of U-shaped plates 510 face upward, facilitating the condensate pipe to enter the gap between the U-shaped plates 510.

[0038] The moving mechanism 600 includes a first C-shaped plate 630 and a second C-shaped plate 640. The first C-shaped plate 630 and the second C-shaped plate 640 are respectively located on opposite sides of the frame body 230. A plurality of jacks 602 are provided on one side of each of the first C-shaped plate 630 and the second C-shaped plate 640. The plurality of jacks 602 correspond to the plurality of grinding mechanisms 500 one by one. The plurality of grinding mechanisms 500 are staggeredly and fixedly connected inside the jacks 602 on the first C-shaped plate 630 and the second C-shaped plate 640. Two U-shaped frames 610 are fixedly connected to the bottom of opposite sides of the frame body 230. A guide wheel 611 is rotatably connected between one ends of the two arms of the four U-shaped frames 610. A transmission belt 620 is rotatably sleeved between the outer side walls of two guide wheels 611 that are respectively located on opposite sides of the frame body 230 and are parallel. The bottom surface of the first C-shaped plate 630 is fixedly connected to the top surface of the two transmission belts 620, and the inner bottom surface of the second C-shaped plate 640 is fixedly connected to the bottom surface of the two transmission belts 620. A second electric push rod 660 is fixedly connected to the outer side wall of the connecting pipe 240, and the movable end of the second electric push rod 660 is fixedly connected to the bottom surface of the second C-shaped plate 640. The number of the plurality of grinding mechanisms 500 is an even number, so that the plurality of grinding mechanisms 500 can be evenly dispersed on opposite sides of the gear lever 250, and the number of grinding mechanisms 500 on opposite sides of the gear lever 250 is the same. And among any two adjacent grinding mechanisms 500, the placement directions of these two grinding mechanisms 500 are the same. The outer side wall of a fixed rod 540 on one U-shaped plate 510 is rotatably connected to the inner side wall of the corresponding jack 602 on the first C-shaped plate 630, and the other fixed rod 540 is movably inserted into the corresponding jack 602 on the second C-shaped plate 640. The outer side wall of a fixed rod 540 on the other U-shaped plate 510 is rotatably connected to the inner side wall of the corresponding jack 602 on the second C-shaped plate 640, and the other fixed rod 540 is movably inserted into the corresponding jack 602 on the first C-shaped plate 630. The plurality of condenser tubes are placed into the top opening of the rectangular tube 200, and the insertion plate 242 is inserted into the two sliding insertion holes 241 to limit the condenser tubes, so that the condenser tubes automatically fall into the gap between two adjacent U-shaped plates 510. Then the insertion plate 242 is taken out, and the pressing mechanism 300 is started to control the movement of the plurality of condenser tubes. When the second electric push rod 660 is started and its movable end makes a reciprocating telescopic movement, the two transmission belts 620 can be pulled by the second C-shaped plate 640 to rotate reciprocally, so as to drive the first C-shaped plate 630 and the second C-shaped plate 640 to move towards each other or away from each other at the same time. At this time, since any two adjacent U-shaped plates 510 are driven by the first C-shaped plate 630 and the second C-shaped plate 640 respectively, the moving directions of any two adjacent U-shaped plates 510 are opposite, so that any two adjacent U-shaped plates 510 can rub and rotate the condenser tube between the two adjacent U-shaped plates 510 through the grinding wire mesh 561, so that the tube surface of the condenser tube rotates to increase the contact surface with the grinding wire mesh 561, and the condenser tube can contact the grinding wire mesh 561 more comprehensively to receive grinding.Thus, multiple condenser pipes can be polished simultaneously, improving the polishing effect.

[0039] The top surfaces of the gear lever 250 and the multiple U-shaped plates 510 are both arc-shaped surfaces. The highest points of the arc surfaces of the U-shaped plates 510 on the two polishing mechanisms 500 located at both ends among the multiple polishing mechanisms 500 are respectively located below the opposite sides of the rectangular pipe 200. Moreover, the top surfaces of the multiple U-shaped plates 510 are all in contact with the inner top surface of the frame 230. When multiple condenser pipes fall onto the top surface of the gear lever 250 and the top surfaces of the U-shaped plates 510, they will automatically slide down along their arc surfaces into the gap between the two U-shaped plates 510. When the bottom end of the condenser pipe reaches the side wall of the rectangular pipe 200, it can automatically slide down along the arc surface of the U-shaped plate 510 at the end into the gap between two adjacent U-shaped plates 510, making it difficult for the condenser pipe to get stuck inside the frame 230 and not come out from the connecting pipe 240. Additionally, the highest points of the arc surfaces of the two U-shaped plates 510 that are respectively located on both sides of the gear lever 250 and closest to the gear lever 250 are located below the opposite sides of the gear lever 250, causing the bottom ends of the condenser pipes in all the rectangular pipes 200 to slide into the gap between two adjacent U-shaped plates 510 and not easily fall to other positions.

[0040] The rotating mechanism 700 includes two arc-shaped frames 710, and the bottom surfaces of the two arc-shaped frames 710 are fixedly connected to the top surface of the frame body 230. A ring body 720 is rotatably sleeved between the two arc-shaped frames 710, and the rectangular pipe 200 is located inside the ring body 720. Two square through pipes 730 are fixedly connected to the outer side wall of the ring body 720, and two sliding plates 740 are slidably sleeved inside the two square through pipes 730. One end of each of the two sliding plates 740 is fixedly connected to a guide rod 741. Guide grooves 601 are formed in the inner top surfaces of the first C-shaped plate 630 and the second C-shaped plate 640, and two rack plates 650 are slidably connected inside the two guide grooves 601. Moving grooves 603 whose interiors are connected to the interiors of the adjacent guide grooves 601 are formed in the top surfaces of the first C-shaped plate 630 and the second C-shaped plate 640, and one end of each of the two guide rods 741 penetrates through the two moving grooves 603 respectively. One end of each of the two guide rods 741 is rotatably connected to the top surface of the adjacent rack plate 650. A control motor 750 is fixedly connected to the bottom surface of the frame body 230, and the motor shaft of the control motor 750 penetrates through the top surface of the frame body 230 and is fixedly sleeved with a rubbing wheel 751. The outer side wall of the rubbing wheel 751 is in contact with the inner side wall of the ring body 720. Gear rings 550 are fixedly sleeved on the outer side walls of the two fixed rods 540 located on the same grinding mechanism 500, and the gear rings 550 are meshed with the adjacent rack plates 650. By starting the control motor 750 to drive the rubbing wheel 751 to rotate reciprocally, the ring body 720 rotates reciprocally. The ring body 720 drives the square through pipes 730 and the adjacent sliding plates 740 to rotate reciprocally, so that the two sliding plates 740 pull the adjacent rack plates 650 to move reciprocally through the adjacent guide rods 741. Moreover, the moving directions of the two rack plates 650 are opposite. When a plurality of rubber tubes 560 are inflated by the air pump, the movable end of the second electric push rod 660 reciprocally expands and contracts within a certain range, so that the fixed rods 540 on the U-shaped plate 510 connected to the first C-shaped plate 630 will not be inserted into the jacks 602 on the second C-shaped plate 640 and will not contact the rack plate 650 on the second C-shaped plate 640, and the fixed rods 540 on the U-shaped plate 510 connected to the second C-shaped plate 640 will not be inserted into the jacks 602 on the first C-shaped plate 630 and will not contact the rack plate 650 on the first C-shaped plate 630. And since there is gas inside the rubber tubes 560 of a plurality of grinding mechanisms 500, they are in an inflated state and reach their elastic limit, so that the rubber tubes 560 can drive the two connected circular plates 530 to rotate synchronously, and the rubber tubes 560 on the plurality of U-shaped plates 510 connected to the first C-shaped plate 630 and the rubber tubes 560 on the plurality of U-shaped plates 510 connected to the second C-shaped plate 640 rotate due to the gear rings 550 connected to the end fixed rods 540 being driven by the adjacent rack plates 650, so that all the grinding wire meshes 561 rotate themselves while rubbing the condensing pipe to rotate, thereby grinding the surface of the condensing pipe, so as to improve the grinding effect. Then, after the grinding is completed, the air pump sucks out the air inside all the rubber tubes 560, causing the plurality of rubber tubes 560 to shrink. At this time, the rubber tubes 560 have enough elastic limit to undergo elastic deformation.Then the second electric push rod 660 is started, so that the fixing rod 540 on the U-shaped plate 510 connected to the second U-shaped plate 640 is inserted into the socket 602 on the first U-shaped plate 630, and the fixing rod 540 on the U-shaped plate 510 on the first U-shaped plate 630 is inserted into the second U-shaped plate 640, so that the gears 550 on the two fixing rods 540 at both ends of the same U-shaped plate 510 are respectively in contact with the two tooth plates 650, so that when the ring body 720 reciprocates, the two tooth plates 650 drive the two circular plates 530 on the same U-shaped plate 510 to reciprocate, and the two circular plates 530 rotate in opposite directions, so that the rubber tubes 560 on all the U-shaped plates 510 are twisted by the reciprocating rotation of the two adjacent circular plates 530 and drive the connected grinding screens 561 to twist synchronously, so that the debris can be separated from the grinding screen 561.

[0041] The fixing mechanism 400 includes two clamping plates 410. Rectangular sliding holes 201 are provided on opposite sides of the rectangular tube 200. The two clamping plates 410 are respectively slidably connected to the inside of the two rectangular sliding holes 201. One end of the two clamping plates 410 is rotatably connected to a connecting rod 420. A first electric push rod 430 is fixedly connected to the top surface of the frame 230. A connecting block 431 is fixedly connected to the movable end of the first electric push rod 430. A rotating shaft is fixedly connected to one side of the connecting block 431. One end of the two connecting rods 420 is rotatably connected to the outer wall of the rotating shaft. Since the bottom of the condenser tube falls between two adjacent U-shaped plates 510, when the first electric push rod 430 is started, the first electric push rod 43 The movable end drives the two clamping plates 410 to move toward each other through the two connecting rods 420, so that the two clamping plates 410 clamp the other parts of all the condenser tubes in the rectangular tube 200 and make the condenser tubes in an inclined state, thereby increasing the contact force between the surface of the condenser tube and the polishing screen 561, and fixing the positions of multiple condenser tubes, which are not easily driven by the rotation of the polishing screen 561 or automatically slide down due to their own weight and move out along the connecting tube 240, so that the positions of the condenser tubes can be fixed by the two clamping plates 410, thereby increasing the polishing time thereof, and when the user throws multiple condenser tubes from the top of the rectangular tube 200, it is only necessary to keep the multiple condenser tubes in a vertical state, which is convenient for the user to throw the condenser tubes.

[0042] Two guide plates 440 are fixedly connected to the opposite sides of the rectangular tube 200. The two guide plates 440 located on the same side of the rectangular tube 200 are respectively located at the top and bottom ends of adjacent clamps 410. The guide plates 440 are used to limit the clamps 410 to prevent the clamps 410 from tilting or falling out of the rectangular sliding hole 201 after being driven by the first electric push rod 430 to separate from the interior of the rectangular tube 200.

[0043] The pressing mechanism 300 includes a rotating rod 310, and the bottom end of the rotating rod 310 is rotatably connected to the top surface of the frame body 230. The top end of the rotating rod 310 is fixedly connected with a connecting plate 320, and two support arms 340 are fixedly connected to the top surface of the connecting plate 320. A winch 350 is rotatably connected between the top ends of the two support arms 340. A driving motor 330 is fixedly connected to the top surface of the connecting plate 320, and the motor shaft of the driving motor 330 penetrates through one support arm 340 and is fixedly connected to the center of one side of the winch 350. A pressing plate 360 is arranged below the winch 350, and the pressing plate 360 is slidably embedded inside the rectangular tube 200. The center of the top surface of the pressing plate 360 is fixedly connected with a pulling rope 362, and one end of the pulling rope 362 is fixedly wound around the outer side wall of the winch 350. Before use, when the condensing pipe needs to be placed into the rectangular tube 200 from the top, the rotating rod 310 is rotated to make the pressing plate 360 move away from above the rectangular tube 200, which is convenient for the user to place the condensing pipe. Then, after the condensing pipe is placed, the rotating rod 310 is reset, and the driving motor 330 is started to drive the winch 350 to rotate, so that the winch 350 lowers the pulling rope 362, making the pressing plate 360 slide into the rectangular tube 200 and press the top end of the condensing pipe to control the descent of the condensing pipe.

[0044] A magnet layer 361 is fixedly connected to the bottom surface of the pressing plate 360. The condensing pipe is generally a galvanized steel pipe. By adsorbing the top end of the condensing pipe through the magnet layer 361, the movement of the condensing pipe in the rectangular tube 200 can be further controlled by the pressing plate 360. And when the pressing plate 360 approaches the two clamping plates 410, the first electric push rod 430 can be started to drive the two clamping plates 410 to clamp towards each other. The adjacent ends of the clamping plates 410 are chamfered structures, which is convenient for the two clamping plates 410 to clamp towards each other to make the top ends of multiple condensing pipes separate from the magnet layer 361.

[0045] A collection groove 101 is opened at the center of the top surface of the base 100, and a slot 102 is opened at the center of the inner bottom surface of the collection groove 101. A vibration motor 220 is fixedly connected to one side of the rectangular tube 200. By the vibration motor 220, the rectangular tube 200 and the frame body 230 vibrate, which is convenient for the condensing pipe to slide along the arc surfaces of the stop rod 250 and the U-shaped plate 510 into the gap between two adjacent U-shaped plates 510 due to vibration when the condensing pipe is placed, and is convenient for the debris adhered to the multiple polishing mechanisms 500 in the frame body 230 to fall into the collection groove 101 and the slot 102. After the pressing plate 360 moves to the clamping plate 410, only the end of the condensing pipe remains unpolished. Then the condensing pipe is clamped by two adjacent rubber hoses 560. The driving motor 330 is started to drive the winch 350 to pull back the pressing plate 360 to make it separate from the condensing pipe. Then the condensing pipe falls off the rubber hose 560 after being polished due to its own weight and the rotation of the rubber hose 560 and falls into the slot 102 from the connecting pipe 240. Then the user takes out multiple condensing pipes. If there is any omission in the polishing of the top end of the condensing pipe, the user can manually polish the coating at the end of the condensing pipe to remove it.

[0046] Working principle: When in use, controllers are respectively arranged on the top surface and the bottom surface of the frame body 230 to control the opening and closing of the first electric push rod 430, the second electric push rod 660 and the control motor 750, a controller is arranged at the connecting plate 320 to control the opening and closing of the driving motor 330, a controller is arranged on the air pump to control its opening and closing, and the air outlet end of the air pump is connected with a plurality of conduits 542 through connecting pieces such as a multi-way valve;

[0047] The user rotates the rotating rod 310 to disengage the pressing plate 360 from above the rectangular tube 200. The insertion plate 242 is inserted into the two sliding insertion holes 241. Then, multiple condenser tubes are lifted and vertically placed at the top opening of the rectangular tube 200. The vibration motor 220 is started to drive the rectangular tube 200 and the frame 230 to vibrate, so that the bottom ends of the condenser tubes automatically fall into the gap between two adjacent U-shaped plates 510 due to vibration and are located above the insertion plate 242. Then, the rotating rod 310 is reset, and the driving motor 330 is started to drive the winch 350 to lower the pulling rope 362, so that the pressing plate 360 slides into the rectangular tube 200, and the magnet layer 361 adsorbs the tops of multiple condenser tubes. Then, the air pump is started to inflate the multiple rubber tubes 560, so that the multiple rubber tubes 560 drive the connected polishing wire meshes 561 to closely adhere to the outer side walls of the condenser tubes. Then, the insertion plate 242 is pulled out of the two sliding insertion holes 241. Then, the first electric push rod 430 is started. The movable end of the first electric push rod 430 drives the two clamping plates 410 to move towards each other through the two connecting rods 420, which will cause the two clamping plates 410 to clamp the other parts of all the condenser tubes in the rectangular tube 200 and make the condenser tubes in an inclined state, increasing the contact force between the surface of the condenser tubes and the polishing wire mesh 561 and fixing the positions of the multiple condenser tubes. The tops of the condenser tubes will slide on the magnet layer 361. Then, the second electric push rod 660 is started and its movable end makes a reciprocating telescopic movement within a certain range. By pulling the two transmission belts 620 to rotate reciprocally through the second C-shaped plate 640, the first C-shaped plate 630 and the second C-shaped plate 640 are simultaneously driven to move towards each other or away from each other. At this time, since any two adjacent U-shaped plates 510 are driven by the first C-shaped plate 630 and the second C-shaped plate 640 respectively, the moving directions of any two adjacent U-shaped plates 510 are opposite, so that any two adjacent U-shaped plates 510 can rub and rotate the condenser tubes between the two adjacent U-shaped plates 510 through the polishing wire mesh 561, so that the tube surfaces of the condenser tubes are rotated to increase the contact surface with the polishing wire mesh 561. And when the condenser tubes are clamped and inclined by the two clamping plates 410, the two adjacent rubber tubes 560 can still rub and rotate the inclined condenser tubes. And at this time, the fixing rod 540 on the U-shaped plate 510 connected to the first C-shaped plate 630 will not be inserted into the jack 602 on the second C-shaped plate 640 and will not contact the toothed plate 650 on the second C-shaped plate 640. The fixing rod 540 on the U-shaped plate 510 connected to the second C-shaped plate 640 will not be inserted into the jack 602 on the first C-shaped plate 630 and will not contact the toothed plate 650 on the first C-shaped plate 630;

[0048] Meanwhile, start the control motor 750 to drive the rubbing wheel 751 to rotate reciprocally, driving the ring body 720 to rotate reciprocally. The ring body 720 drives the square tube 730 and the adjacent slide plate 740 to rotate reciprocally, causing the two slide plates 740 to pull the adjacent toothed plates 650 to move reciprocally through the adjacent guide rods 741. Moreover, the moving directions of the two toothed plates 650 are opposite, causing the rubber tubes 560 inside the multiple polishing mechanisms 500 to be inflated due to the presence of gas and reach their elastic limit. Thus, the rubber tubes 560 can drive the two connected circular plates 530 to rotate synchronously, causing the rubber tubes 560 on the multiple U-shaped plates 510 connected to the first C-shaped plate 630 and the rubber tubes 560 on the multiple U-shaped plates 510 connected to the second C-shaped plate 640 to rotate because the gears 550 connected to the end fixing rods 540 are driven by the adjacent toothed plates 650. Therefore, all the polishing wire meshes 561 rotate themselves while rubbing the condensate pipe to polish the surface of the condensate pipe. After the polishing is completed, the first electric push rod 430 can be started to drive the two clamping plates 410 to reset. Then, start the driving motor 330 to lower the pulling rope 362 to drive the multiple condensate pipes to move downwards by a certain amount. Then, start the first electric push rod 430 again to use the clamping plates 410 to limit the multiple condensate pipes and polish them again;

[0049] When multiple condensate pipes are polished to the top, the pressing plate 360 approaches the two clamping plates 410. Then, start the first electric push rod 430 to drive the two clamping plates 410 to clamp towards each other, shoveling the multiple condensate pipes off the magnet layer 361. Then, the top of the condensate pipe falls to the slot 102 after being polished by the multiple polishing wire meshes 561. Then, the user takes out the multiple condensate pipes in the slot 102. If there is still a part of the top of the condensate pipe that has not separated from the coating, manually remove it. Then, start the air pump to suck the air in the multiple rubber tubes 560, causing the multiple rubber tubes 560 to drive the connected polishing wire meshes 561 to contract by a certain amount, and the debris adhering to them to fall due to the deformation of the polishing wire meshes 561 and the vibration of the vibration motor 220. Then, start the second electric push rod 660, causing the fixing rods 540 on the U-shaped plates 510 connected to the second C-shaped plate 640 to insert into the internal jacks 602 on the first C-shaped plate 630, and the fixing rods 540 on the U-shaped plates 510 on the first C-shaped plate 630 to insert into the second C-shaped plate 640, so that the gears 550 on the two fixing rods 540 at both ends of the same U-shaped plate 510 are respectively in contact with the two toothed plates 650. Thus, when the ring body 720 rotates reciprocally, the two toothed plates 650 drive the two circular plates 530 on the same U-shaped plate 510 to rotate reciprocally, and the rotation directions of these two circular plates 530 are opposite when rotating. Therefore, all the constricted rubber tubes 560 on the U-shaped plates 510 are reciprocally twisted by the reciprocal rotation of the adjacent two circular plates 530 and drive the connected polishing wire meshes 561 to twist synchronously, facilitating the detachment of the debris from the polishing wire meshes 561. After the debris falls to the collection tank 101, sweep out the debris in the collection tank 101 and conduct centralized treatment.
