Description

Technical Field

[0001] The utility model belongs to the technical field of ice making machines, in particular to a scraper for an ice making machine. Background Art

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator with the refrigerant of a refrigeration system. It uses a refrigeration system and water as a carrier. It makes ice by passing through a specific device under power-on. The scraper in the ice maker is a key component in the ice making system, especially in the system that uses the scraper method to make ice. The working principle of the scraper method ice making system is that the evaporator is two concentric cylinders, the interlayer between the cylinders is filled with refrigerant, and the inner cylinder is filled with seawater. The refrigerant evaporates and absorbs heat in the interlayer, and the heat of the seawater in the inner cylinder is absorbed, generating a large number of ice crystals on the wall of the inner cylinder. At the same time, the rotating shaft fixed at the center of the circle rotates at a high speed, and the scraper installed on the rotating shaft, i.e., the scraper, scrapes off the ice crystals generated on the wall, mixes with the seawater, and forms fluidized ice.

[0003] The Chinese patent with the publication number "CN207487199U" discloses a scraper device for a marine seawater ice maker, comprising an evaporator, a rotating shaft arranged on the axis of the evaporator, and a scraper assembly arranged on the rotating shaft; the scraper assembly comprises a scraper and a connecting plate connected to the scraper at one end and connected to the rotating shaft at the other end; the connecting plate comprises a right-angle fixing plate and a baffle, the right-angle side of the right-angle fixing plate is connected to the rotating shaft, one end of the baffle is connected to the other right-angle side of the right-angle fixing plate; the other end of the baffle is connected to the scraper. The scraper device provided by the utility model has a simple structure and has a good ice scraping effect.

[0004] During use, the above-mentioned device uses bolts to assist in the installation of the scraper structure, and the scraper structure is located inside the evaporator as a whole. The scraper structure is obviously not convenient for quick disassembly and maintenance. The scraper is located inside the evaporator and needs to be scraped off the ice frequently. After long-term use, the scraper and ice are squeezed and collided and are very likely to be damaged. It can be seen that the overall disassembly, assembly, inspection and maintenance are extremely cumbersome and inconvenient, so it needs to be improved. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a scraper for an ice maker to solve the problems raised in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] The scraper for ice making machine comprises an evaporator, a lifting mechanism is fixedly installed in the middle of one side of the evaporator, a top cover is fixedly installed on the top of the lifting mechanism, a scraper mechanism is fixedly installed on the bottom of the top cover, and the scraper mechanism is plugged into the inside of the evaporator;

[0008] The lifting mechanism comprises a rear track, the rear track is fixedly installed at the middle of the back side of the evaporator, a first motor is fixedly installed at the bottom of the rear track, a lead screw is fixedly installed at the output end of the first motor through the rear track, the lead screw is rotatably connected to the inner side of the rear track, a sliding rod is threadedly connected to the outer surface of the lead screw, a mounting bracket is fixedly installed on the top of the sliding rod, and the mounting bracket is fixedly connected to the top of the top cover by bolts;

[0009] The scraper mechanism includes a second motor and a rotating shaft. The second motor is fixedly installed in the middle of the top of the top cover. The rotating shaft is rotatably connected to the middle of the bottom of the top cover. The output end of the second motor is fixedly connected to the top of the rotating shaft. The outer surface of the rotating shaft is fixedly installed with a concave frame at equal intervals. The outer side of the concave frame is fixedly installed with a clamping component. The outer side of the clamping component is fixedly installed with an elastic component. The outer end of the elastic component is fixedly installed with a substrate. The outer side of the substrate is fixedly installed with a scraper body. The scraper device for the ice maker consists of an evaporator, a lifting mechanism and a scraper mechanism. The lifting mechanism is installed in the middle of one side of the evaporator. The top of the mechanism is equipped with a top cover. The scraper mechanism is fixed at the bottom of the top cover to ensure that the scraper can be inserted into the evaporator. The lifting mechanism is mainly composed of a rear track, a first motor, a screw rod, a sliding rod and a mounting frame. The rear track is fixed to the back of the evaporator, and a screw rod is installed inside. It is driven to rotate by the first motor. The sliding rod on the screw rod is threaded to slide up and down, thereby driving the mounting frame and the top cover to move up and down, so that the scraper mechanism can be pulled out from the inside of the evaporator, which is convenient for maintenance and replacement. The mechanism includes a second motor, a rotating shaft, a concave frame, a clamping assembly, an elastic assembly, a substrate and a scraper body. The second motor drives the rotating shaft to rotate, thereby driving the concave frame and the clamping assembly and the elastic assembly thereon to rotate. The scraper body is fixed to the outer end of the elastic assembly through the substrate. As the rotating shaft rotates, the scraper body de-ices the inside of the evaporator. The limit spring in the elastic assembly ensures that the scraper body always fits tightly against the inside of the evaporator, thereby improving the scraping efficiency. This design enables the scraper mechanism to de-ice efficiently. At the same time, the setting of the lifting mechanism also greatly facilitates the inspection and replacement of the scraper mechanism.

[0010] As a preferred technical solution, the card-mounted assembly includes a mounting rail, which is fixedly mounted on the outer side of the concave frame, and a limiting piece is fixedly mounted on the top of the mounting rail. A sliding rod is slidably connected to the inside of the mounting rail, and the outer side of the sliding rod is fixedly connected to the elastic assembly. The mounting rail is fixed to the outer side of the concave frame to provide a stable supporting structure; the limiting piece is installed on the top of the mounting rail to ensure the stability of the sliding rod during the sliding process to prevent it from excessive movement or falling off, and the sliding rod is fixedly connected to the elastic assembly so that the scraper body can maintain appropriate pressure and fit during the de-icing process, thereby improving the ice scraping efficiency. This design allows the card-mounted assembly to support the scraper mechanism while also facilitating its disassembly, assembly and maintenance.

[0011] As an optimal technical solution, the limit member includes a top rail, a limit spring is fixedly installed on the inner side of the top rail at equal intervals, a limit plate is fixedly installed on the outer end of the limit spring, a limit shaft is fixedly installed in the middle of the outer end of the limit plate, and the ends of the limit shaft are inserted into the upper and lower ends of the elastic component. The limit member is mainly composed of a top rail, a limit spring, a limit plate and a limit shaft. They work together to achieve stable support and convenient disassembly and assembly of the scraper mechanism. The top rail, as the main structure of the limit member, is fixedly installed on the top of the mounting rail to provide support and positioning for other components. The limit springs fixedly installed at equal intervals play a role of buffering and resetting. Their outer ends are connected to the limit plate, so that the limit plate can move when subjected to external force and reset after the external force disappears. The limit shaft fixedly installed in the middle of the outer end of the limit plate plays a role of limiting the sliding range of the slide rod and locking the scraper mechanism.

[0012] As a preferred technical solution, an adjusting plate is fixedly installed on the top of the limit plate near one end of the elastic component, and the inner side of the mounting rail and the overall cross-sectional shape of the slide rod are both set to a convex shape. An adjusting plate is fixedly installed on the top of the limit plate near one end of the elastic component. This design allows the operator to easily move the limit plate by pushing the adjusting plate when the scraper mechanism needs to be disassembled. The setting of the adjusting plate increases the convenience of operation and makes the disassembly process simpler and more efficient. In addition, the inner side of the mounting rail and the overall cross-sectional shape of the slide rod are both set to a convex shape. This design ensures the stability and accuracy of the slide rod sliding inside the mounting rail. The convex cross-sectional shape can effectively prevent the slide rod from deviating or shaking when sliding in the mounting rail, thereby ensuring the stability and reliability of the scraper mechanism during operation.

[0013] As an optimal technical solution, the elastic component includes a concave seat, which is fixedly installed on the outer side of the slide rod, and telescopic springs are fixedly installed on the inner side of the concave seat at equal intervals. The outer ends of the telescopic springs are fixedly connected to the substrate, and the top and bottom of the concave seat are fixedly installed with limit rings, and the end of the limit shaft is inserted into the interior of the limit ring. The elastic component is mainly composed of a concave seat, a telescopic spring, a limit ring and a substrate, which work together to ensure the stability and efficiency of the scraper mechanism during the deicing process. The concave seat is fixedly installed on the outer side of the slide rod to provide an installation basis for the telescopic spring. The telescopic spring is fixedly fixed on the inner side of the concave seat at equal intervals, and its outer end is fixedly connected to the substrate. When the scraper body encounters resistance during the deicing process, the telescopic spring can be telescoped and deformed, thereby absorbing the impact force and protecting the scraper body and the overall structure from damage.

[0014] As a preferred technical solution, a support shaft is fixedly installed at the inner lower end of the substrate, and the end of the support shaft is inserted into the inner side of the limiting ring at the lower end of the concave frame. The substrate is connected to the limiting ring at the lower end of the concave frame by the support shaft, which can effectively prevent the scraper body from shaking or shifting during the de-icing process, thereby ensuring that it can fit tightly to the surface of the evaporator and improve the ice scraping efficiency. At the same time, this design also takes into account the convenience of disassembly and assembly of the scraper mechanism. When the scraper body needs to be inspected or replaced, the operator can easily remove the scraper mechanism from the concave frame by releasing the connection between the support shaft and the limiting ring. This design not only simplifies the disassembly process, but also reduces maintenance costs and improves work efficiency.

[0015] As a preferred technical solution, a fixing frame is fixedly installed in a circular arrangement at equal intervals at the bottom of the evaporator, and mounting holes are opened at the outer end of the fixing frame, and the mounting holes are configured as countersunk holes. The design of the fixing frame arranged in a circular arrangement at equal intervals at the bottom of the evaporator not only provides a stable support structure, but also facilitates the installation and positioning of the scraper mechanism. The mounting holes opened at the outer end of the fixing frame adopt a countersunk hole design. This countersunk hole has the advantages of a firm connection and is not easy to loosen, and can ensure that the scraper mechanism remains stable during operation. The countersunk hole is a special hole structure, which is characterized in that a blind hole is machined inward from the surface of an object, and is often used for installing bolts or other connecting parts. The countersunk hole is opened at the outer end of the fixing frame, and bolts and other fasteners can be easily installed to firmly fix the scraper mechanism on the evaporator. This design takes into account both the stability of the structure and the convenience of installation.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] First, by setting the card-mounted assembly of the scraper mechanism, the device can be easily operated when in use. When maintenance is required, the lifting mechanism moves the scraper out of the evaporator. After the slide bar slides into the mounting rail, the limit spring pushes the limit plate, so that the limit shaft is inserted into the limit ring to lock the scraper. If the scraper needs to be replaced, the adjustment plate is pushed to move the limit plate inward, the limit shaft is separated from the limit ring, and the slide bar can be pulled out, so that quick disassembly and assembly are achieved, and the convenience of maintenance is improved;

[0018] Second, by setting up a lifting mechanism, the device can conveniently disassemble and overhaul the scraper mechanism. It only needs to start the first motor to drive the screw rod to rotate, thereby driving the sliding rod to slide in the track. The up and down movement of the sliding rod will prompt the mounting frame to drive the top cover to move, so that the scraper mechanism can be pulled out of the evaporator. This design improves the convenience of disassembly and assembly of the scraper mechanism and optimizes the overall overhaul process.

[0019] Third, by setting up a scraper mechanism, the device can remove ice efficiently. The second motor is started to drive the rotating shaft to rotate, which in turn drives the concave frame and the clamping and elastic components to rotate. The scraper body then removes ice from the inside of the evaporator. At the same time, the limit spring in the elastic component is reset to ensure that the scraper body fits tightly against the inside of the evaporator, thereby improving the scraping efficiency.

The outer side of the base plate 46 is fixedly installed with a scraper body 47. The scraper device for the ice maker consists of an evaporator 1, a lifting mechanism 2 and a scraper mechanism 4. The lifting mechanism 2 is installed in the middle of one side of the evaporator 1. A top cover 3 is installed on the top of the mechanism, and the scraper mechanism 4 is fixed at the bottom of the top cover 3 to ensure that the scraper can be inserted into the evaporator 1.

The rear track 21 is fixed to the back of the evaporator 1, and a screw rod 23 is installed inside, and is driven to rotate by the first motor 22. The sliding rod 24 on the screw rod 23 is threadedly connected to slide up and down, thereby driving the mounting frame 25 and the top cover 3 to move up and down, so that the scraper mechanism 4 can be pulled out from the inside of the evaporator 1 for easy maintenance and replacement. The scraper mechanism 4 includes The second motor 41, the rotating shaft 42, the concave frame 43, the clamping assembly 44, the elastic assembly 45, the base plate 46 and the scraper body 47. The second motor 41 drives the rotating shaft 42 to rotate, thereby driving the concave frame 43 and the clamping assembly 44 and the elastic assembly 45 thereon to rotate. The scraper body 47 is fixed to the outer end of the elastic assembly 45 through the base plate 46. As the rotating shaft 42 rotates, the scraper body 47 de-ices the inside of the evaporator 1. The limit spring 4422 in the elastic assembly 45 ensures that the scraper body 47 is always tightly fitted to the inside of the evaporator 1, thereby improving the ice scraping efficiency. This design enables the scraper mechanism 4 to efficiently perform de-icing work. At the same time, the setting of the lifting mechanism 2 also greatly facilitates the inspection and replacement operations of the scraper mechanism 4.

The sliding rod 443 is fixedly connected to the elastic assembly 45 so that the scraper The main body 47 can maintain appropriate pressure and fit during the de-icing process to improve the ice scraping efficiency. This design allows the card assembly 44 to support the scraper mechanism 4 while also facilitating its disassembly and maintenance. When the scraper main body 47 needs to be replaced or repaired, the slide rod 443 can be slid out of the mounting rail 441 through simple operations, thereby easily disassembling the scraper mechanism 4. This convenience greatly improves the maintenance efficiency of the equipment and reduces maintenance costs. The design of the card assembly 44 fully embodies the combination of practicality and innovation, and provides a strong guarantee for the stable operation and efficient maintenance of the ice maker.

[0030] refer to Figure 1-Figure 4 The limiting member 442 includes a top rail 4421, and limiting springs 4422 are fixedly installed on the inner side of the top rail 4421 at equal intervals. A limiting plate 4423 is fixedly installed on the outer end of the limiting spring 4422, and a limiting shaft 4424 is fixedly installed in the middle of the outer end of the limiting plate 4423. The ends of the limiting shaft 4424 are plugged into the upper and lower ends of the elastic component 45.

They work together to achieve stable support and convenient disassembly and assembly of the scraper mechanism 4. The top rail 4421, as the main structure of the limiting member 442, is fixedly installed on the top of the mounting rail 441 to provide support and positioning for other components. The limiting springs 4422 fixedly installed at equal intervals play a role in The limit plate 4423 is fixedly installed in the middle part of the outer end of the limit plate 4423 to limit the sliding range of the slide bar 443 and lock the scraper mechanism 4. When the scraper mechanism 4 needs to be disassembled, the limit plate 4423 can be pushed to disengage the limit shaft 4424 from the elastic component 45, thereby allowing the slide bar 443 to slide out of the mounting rail 441. This design not only ensures the stability of the scraper mechanism 4 during operation, but also greatly simplifies the disassembly and assembly process and improves the maintenance efficiency. At the same time, the resetting effect of the limit spring 4422 ensures that the scraper mechanism 4 can be accurately reset when reinstalled, thereby ensuring the ice scraping effect.

[0031] refer to Figure 1-Figure 4The top of the limit plate 4423 is fixedly installed with an adjustment plate 4425 near the elastic component 45. The inner side of the mounting rail 441 and the overall cross-sectional shape of the slide bar 443 are both set to a convex shape. The top of the limit plate 4423 is fixedly installed with an adjustment plate 4425 near the elastic component 45. This design allows the operator to easily move the limit plate 4423 by pushing the adjustment plate 4425 when the scraper mechanism 4 needs to be disassembled. The setting of the adjustment plate 4425 increases the convenience of operation and makes the disassembly process simpler and more efficient. In addition, the inner side of the mounting rail 441 and the slide bar 443 are The overall cross-sectional shape of the rod 443 is set to be a convex shape. This design ensures the stability and accuracy of the sliding rod 443 in the mounting rail 441. The convex cross-sectional shape can effectively prevent the sliding rod 443 from deflecting or shaking when sliding in the mounting rail 441, thereby ensuring the stability and reliability of the scraper mechanism 4 during operation.

[0032] refer to Figure 1-Figure 4 The elastic component 45 includes a concave seat 451, which is fixedly installed on the outer side of the sliding rod 443. Telescopic springs 452 are fixedly installed on the inner side of the concave seat 451 at equal intervals. The outer ends of the telescopic springs 452 are fixedly connected to the substrate 46. The top and bottom of the concave seat 451 are fixedly installed with limit rings 453. The end of the limit shaft 4424 is inserted into the interior of the limit ring 453. The elastic component 45 is mainly composed of a concave seat 451, a telescopic spring 452, a limit ring 453 and a substrate 46. They work together to ensure the stability and efficiency of the scraper mechanism 4 during the deicing process.

The telescopic spring 452 is fixedly installed on the inner side of the concave seat 451 at equal intervals, and its outer ends are fixedly connected to the substrate 46. When the scraper body 47 is in When encountering resistance during the de-icing process, the telescopic spring 452 can be telescoped and deformed, thereby absorbing the impact force and protecting the scraper body 47 and the overall structure from damage. What is more ingenious is that the top and bottom of the concave seat 451 are fixedly installed with a limit ring 453, and the end of the limit shaft 4424 is inserted into the inside of the limit ring 453. This design not only ensures the stability of the scraper mechanism 4 during operation and prevents it from shaking or deflecting, but also can move the limit plate 4423 to make the limit shaft 4424 detach from the limit ring 453 when necessary, so as to facilitate the disassembly, assembly and maintenance of the scraper mechanism 4. The design of the elastic component 45 fully considers the various situations that the scraper mechanism 4 may encounter during operation, which not only ensures its stability and durability, but also improves the convenience of maintenance. This design undoubtedly provides a strong guarantee for the normal operation and efficient maintenance of the ice maker.

[0033] refer to Figure 1-Figure 4 The lower inner end of the base plate 46 is fixedly installed with a support shaft 454, and the end of the support shaft 454 is inserted into the inner side of the limiting ring 453 at the lower end of the concave frame 43. The base plate 46 is connected to the limiting ring 453 at the lower end of the concave frame 43 through the support shaft 454, which can effectively prevent the scraper body 47 from shaking or deflecting during the deicing process, thereby ensuring that it can closely fit the surface of the evaporator 1 and improve the ice scraping efficiency.

When the scraper body 47 needs to be repaired or replaced, the operator can easily remove the scraper mechanism 4 from the concave frame 43 by releasing the connection between the support shaft 454 and the limiting ring 453. This design not only simplifies the disassembly process, but also reduces maintenance costs and improves work efficiency. Through the connection design of the support shaft 454 and the limiting ring 453, the scraper mechanism 4 not only ensures working stability and ice scraping efficiency, but also realizes fast and convenient disassembly and assembly and maintenance, providing strong support for the normal operation and efficient maintenance of the ice maker.

[0034] refer to Figure 1-Figure 4 The bottom of the evaporator 1 is evenly spaced and arranged in a ring to fix a fixing frame 5. The outer end of the fixing frame 5 is provided with a mounting hole 6, and the mounting hole 6 is set as a countersunk hole. The design of the fixing frame 5 arranged in a ring at an equal distance at the bottom of the evaporator 1 not only provides a stable support structure, but also facilitates the installation and positioning of the scraper mechanism 4. The mounting hole 6 opened at the outer end of the fixing frame 5 adopts a countersunk hole design. This countersunk hole has the advantages of firm connection and not easy to loosen, which can ensure that the scraper mechanism 4 remains stable during operation. The countersunk hole is a special hole structure, which is characterized by processing a blind hole from the surface of an object to the inside, and is often For installing bolts or other connecting parts, a countersunk hole is opened at the outer end of the fixing frame 5, and bolts and other fasteners can be easily installed to firmly fix the scraper mechanism 4 on the evaporator 1. This design takes into account both the stability of the structure and the convenience of installation, and provides a strong guarantee for the stable operation and efficient maintenance of the ice maker. In addition, the design of the countersunk hole can also effectively prevent bolts and other fasteners from protruding from the surface of the fixing frame 5, reducing possible safety hazards, and also making the entire structure more beautiful. Therefore, this countersunk hole design has been widely used in the fixing frame 5 of the evaporator 1.

[0035] Principle and advantages of use: By setting the clamping assembly 44 of the scraper mechanism 4, the scraper mechanism 4 can be removed from the inside of the evaporator 1 by starting the lifting mechanism 2 when the device is in use. At this time, the sliding rod 443 is slid into the inner side of the mounting rail 441. At this time, the limiting spring 4422 is reset to resist the limiting plate 4423 to move outward. At this time, the limiting plate 4423 can drive the limiting shaft 4424 to be inserted into the inner side of the limiting ring 453 of the concave seat 451, and then the other end of the sliding rod 443 can be limited. At this time, the scraper body 4 can be removed. 7 is locked and installed on the outer side of the concave frame 43. When the scraper body 47 needs to be removed and replaced, the limiting plate 4423 can be driven toward the rotating shaft 42 by pushing the adjustment plate 4425, and then the limiting plate 4423 can be adjusted to retract into the inside of the top rail 4421. The inward movement of the limiting plate 4423 can cause the limiting shaft 4424 to be separated from the inner side of the limiting ring 453 at the upper end. At this time, the sliding rod 443 can be adaptively withdrawn from the inner side of the mounting rail 441, so that the device as a whole can be quickly repaired and disassembled, which can improve the convenience of disassembling and repairing the scraper body 47 of the device as a whole;

[0036] By setting the scraper mechanism 4, during use, the device can be operated by starting the second motor 41, and the second motor 41 is used to drive the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 can drive the concave frame 43 to rotate, and the rotation of the rotating shaft 42 can drive the clamping assembly 44 and the elastic assembly 45 to rotate. At this time, the scraper body 47 can be driven to scrape and remove ice from the inside of the evaporator 1, which can play a better de-icing effect. During the de-icing period, the limit spring 4422 on the inner side of the concave seat 451 of the elastic assembly 45 is reset, which can resist the scraper body 47 to fit the inner side of the evaporator 1. As the scraper body 47 rotates, the elastic force of the limit spring 4422 acts on the scraper body 47, so that the scraper body 47 can always fit the inner side of the evaporator 1, which can improve the overall ice scraping efficiency of the scraper body 47.

[0037] By setting up the lifting mechanism 2, the device can be operated by starting the first motor 22 during use, and the first motor 22 drives the screw rod 23 to rotate, that is, the rotation of the screw rod 23 can drive the sliding rod 24 to slide inside the rear track 21, and the sliding rod 24 can slide up and down to assist in driving the mounting frame 25 to move the top cover 3 up and down. The scraper mechanism 4 can be pulled out from the inside of the evaporator 1 by the up and down movement of the top cover 3, so that the scraper mechanism 4 can be disassembled and repaired conveniently, and the convenience of overall inspection and disassembly of the device can be improved.
