Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment production and processing devices, in particular to a condenser covering tooling. Background Art

[0002] During the manufacturing process of refrigerators, freezers and other refrigeration equipment, the condenser needs to be pasted to the box shell with aluminum foil tape. In the prior art, due to the lack of special pasting tools, the pasting operation of the condenser is generally divided into three steps: ①. Placing the condenser; ②. Preliminary pasting of the aluminum foil tape; ③. Pipe straightening, that is, pressing the aluminum foil tape on the condenser to ensure that there is no gap between the aluminum foil tape, the condenser and the box shell.

[0003] The manual covering operation of the prior art condenser has the following disadvantages and shortcomings: ①. There are too many processes, which affects the production rhythm and is too inefficient; ②. The aluminum foil tape is easily punctured when the tube is manually fixed. If the aluminum foil tape is punctured, the foaming material will flow into the gap between the condenser and the box shell along the gap, resulting in poor heat dissipation and thus affecting the refrigeration effect.

[0004] In order to improve the quality and efficiency of condenser coating, the existing technology is improved to solve the shortcomings of the existing technology.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In view of the problems pointed out in the background technology, the utility model proposes a condenser covering tool, which can realize tape covering and pipe wholeing at the same time, effectively improving the covering efficiency and covering quality of the condenser.

[0007] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions:

[0008] In some embodiments of the present application, a condenser coating tool is provided, comprising:

[0009] A shell, in which a tape roller, a tube roller and a guide roller are rotatably arranged, wherein the axes of the tape roller, the tube roller and the guide roller are parallel to each other, a through portion is formed at the bottom of the shell, and the bottoms of the tube roller and the guide roller are exposed below the through portion;

[0010] An annular tube-straightening groove coaxial with the tube-straightening roller is formed on the outer circumferential surface thereof, and an annular guide groove coaxial with the tube-straightening roller is formed on the outer circumferential surface thereof; the tube-straightening roller and the guide roller are arranged at intervals along the tape coating direction, and the positions of the annular tube-straightening groove and the annular guide groove both correspond to the same condenser tube to be coated on the condenser.

[0011] The condenser covering tool in some embodiments of the present application includes a shell and a tape roller, a tube straightening roller and a guide roller arranged in the shell. The tape roller is used to install the tape roll, and the tube straightening roller is used to straighten the tube. The tape is squeezed by the tube straightening wheel. As the tool rolls, the tape can be firmly pressed against the shell, that is, the tape is pressed against the condenser tube during the tape covering process, thereby combining the two processes of tape covering and condenser tube straightening into one, saving the operating time and the labor hours required for a single product, and improving the condenser covering efficiency. At the same time, the manual tube straightening process is converted into a tool execution process and standardized, thereby improving the condenser covering quality and reducing the risk of manual tube straightening causing the aluminum foil tape to be punctured, resulting in poor foaming and thus affecting the refrigeration effect.

[0012] In some embodiments of the present application, there is an arc transition between the annular whole tube groove and the outer peripheral surface area of ​​the whole tube roller located on both sides thereof, and the transition arc at the arc transition is tangent to the same condenser tube, thereby improving the fit between the tape and the condenser tube and further improving the condenser tube coating quality.

[0013] In some embodiments of the present application, a plurality of recessed portions are formed on the outer peripheral surface of the tube-forming roller on both sides of the annular tube-forming groove, and the plurality of recessed portions are arranged at intervals along the circumference of the outer peripheral surface of the tube-forming roller. When the tube-forming roller presses the tape onto the condenser tube during tape lamination, the plurality of recessed portions can squeeze out the air between the tape and the tube-forming roller in time, so that the tape and the condenser tube fit as closely as possible, further improving the lamination quality.

[0014] In some embodiments of the present application, the recessed portion is strip-shaped and extends in a direction parallel to the axial direction of the whole tube roller. The recessed portions on the outer peripheral surface area of ​​the whole tube roller on both sides of the annular whole tube groove are arranged one by one opposite to each other.

[0015] By setting the recessed portion as a strip-shaped recessed portion extending in a direction parallel to the axial direction of the whole tube roller, since the axial direction of the whole tube roller is parallel to the width direction of the tape, that is, perpendicular to the coating direction of the tape, the air between the tape and the whole tube roller can be quickly discharged.

[0016] In some embodiments of the present application, the tape roller is located between the whole tube roller and the guide roller, and the tape roller is located obliquely above the whole tube roller. A guide component is also provided in the shell for guiding the coating section of the tape roll to the bottom of the whole tube roller, so that the coating tape can be smoothly guided to the bottom of the whole tube wheel, which is beneficial to ensuring the coating quality.

[0017] In some embodiments of the present application, the guide component is located below the tape roller and between the full tube roller and the guide roller, and the guide component has an outwardly convex arc-shaped guide portion for contacting the covering section of the tape roll. The guide component contacts the tape through its outwardly convex arc-shaped guide portion to prevent the tape from being punctured.

[0018] In some embodiments of the present application, a cutting knife is provided at the front of the shell for cutting the tape. The cutting edge of the cutting knife is exposed below the through-hole portion, so the tape can be cut anytime when needed without the need for an additional knife, which is convenient to use.

[0019] In some embodiments of the present application, the shell includes a first shell part and a second shell part, and the first shell part and the second shell part are detachably connected as a whole to facilitate the installation and replacement of various components inside the shell.

[0020] In some embodiments of the present application, the inner walls of the first shell part and the second shell part are formed with relatively arranged tape roller mounting parts, whole tube roller mounting parts and guide roller mounting parts, which are respectively used to rotatably mount the tape roller, the whole tube roller and the guide roller.

[0021] In some embodiments of the present application, a gripping portion is formed on the shell to facilitate gripping operations; a plurality of reinforcing ribs are formed on the inner wall of the shell to increase the structural strength of the entire tooling; the top of the shell is open to at least expose the tape roller and the whole tube roller to facilitate observation of the use of the tape roll and the whole tube roller.

[0044] During the manufacturing process of refrigerators, freezers and other refrigeration equipment, the condenser needs to be attached to the housing of the refrigerator, freezer and other refrigeration equipment using tape (usually aluminum foil tape). In some embodiments of the present application, a condenser attaching tool is provided for attaching the condenser to the housing of the refrigeration equipment using aluminum foil tape.

[0045] Figure 1 is a structural schematic diagram of a condenser covering tooling according to an embodiment; Figure 2 for Figure 1 A top view of Figure 3 It is a structural schematic diagram of the condenser covering tooling in use according to the embodiment; Figure 4 for Figure 3 Top view of the .

[0046] Reference Figures 1 to 4 In some embodiments of the present application, a condenser pasting tool 1 is provided, which is specifically used for pasting a condenser on a refrigerator on a refrigerator shell. A condenser pasting tool 1 includes a shell 10, and a tape roller 20, a pipe roller 30 and a guide roller 40 are rotatably arranged inside the shell 10.

[0047] The tape roller 20 is a cylindrical roller, which is used to install the rolled aluminum foil tape (hereinafter referred to as the tape roll 2). The tape roll 2 is unwound as the tape roller 20 rotates to attach the condenser to the refrigerator body. When attaching, the condenser tubes 3 are attached one by one, that is, after the condenser is placed on the refrigerator shell, the condenser attaching tool 1 is rolled along the length direction of each condenser tube 3, and the condenser tubes 3 are attached to the refrigerator shell one by one, thereby completing the attachment of the entire condenser.

[0048] The tape roller 20, the whole tube roller 30 and the guide roller 40 are located at different positions in the shell 10, and the axes of the tape roller 20, the whole tube roller 30 and the guide roller 40 are parallel to each other. A through portion 11 is formed at the bottom of the shell 10, and the bottoms of the whole tube roller 30 and the guide roller 40 are exposed below the through portion 11, so that the whole tube roller 30 can smoothly contact and press the aluminum foil tape during lamination, and the guide roller 40 can also smoothly contact the condenser tube 3; with the rolling of the tooling, the tape roller 20 and the whole tube roller 30, the aluminum foil tape can be firmly pressed on the refrigerator shell.

[0049] The whole tube roller 30 and the guide roller 40 are also cylindrical rollers. An annular whole tube groove 31 coaxial with the whole tube roller 30 is formed on the outer circumference of the whole tube roller 30, and an annular guide groove 41 coaxial with the whole tube roller 40 is formed on the outer circumference of the guide roller 40. The guide roller 40 is used to guide and cooperate with the condenser tube 3 during pasting to play a guiding role.

[0050] The whole tube roller 30 and the guide roller 40 are arranged at intervals along the tape coating direction, that is, they are arranged front and back. When the condenser coating tool 1 in the embodiment of the present application coats the condenser tubes 3 one by one, taking one of the condenser tubes 3 as an example, the annular whole tube groove 31 of the whole tube roller 30 and the annular guide groove 41 of the guide roller 40 are both stuck on the same condenser tube 3, and the aluminum foil tape is pressed between the whole tube roller 30 and the condenser tube 3. The annular guide groove 41 of the guide roller 40 directly contacts with the condenser tube 3, so that the whole tool rolls and coats (the coating direction is as shown in FIG. Figure 3 and Figure 4 When the condenser tube 3 is rolled along the extension direction thereof (as shown by the middle arrow I), the condenser tube 3 can be avoided from deviating from the condenser tube 3, thereby ensuring the pasting quality.

[0051] The positions of the annular tube whole groove 31 and the annular guide groove 41 both correspond to the same condenser tube 3 to be coated on the condenser, that is, when the annular tube whole groove 31 is clamped across the condenser tube 3, the annular guide groove 41 is also clamped across the condenser tube 3, and the two are arranged front and back along the extension direction of the same condenser tube 3. In this way, the tube whole roller 30 and the guide roller 40 cooperate together to enable the entire tooling to roll along the extension direction of the same condenser tube 3 during rolling coating, avoiding deviation from the condenser tube 3 and ensuring the coating quality.

[0052] The condenser covering tool 1 in some embodiments of the present application can realize the combination of the two processes of tape covering and condenser pipe finishing into one, saving the operation cycle and the man-hours required for a single product, and improving the condenser covering efficiency; at the same time, the manual pipe finishing process is converted into a process performed using this tool, which is standardized, thereby improving the condenser covering quality and reducing the risk of manual pipe finishing causing the aluminum foil tape to be punctured, resulting in poor foaming and thus affecting the refrigeration effect.

[0053] In some embodiments of the present application, reference Figures 5 to 7 , while combining Figures 1 to 4 There is an arc transition between the annular whole tube groove 31 and the outer peripheral surface area 32 of the whole tube roller on both sides thereof, and the transition arc R at the arc transition is tangent to the same condenser tube 3 (that is, the condenser tube 3 that is simultaneously clamped by the annular whole tube groove 31 and the annular guide groove 41), thereby improving the degree of adhesion between the tape and the condenser tube 3 and further improving the coating quality of the condenser tube 3; and by contacting and pressing the transition arc with the aluminum foil tape, it is also possible to avoid puncturing the aluminum foil tape, thereby avoiding the risk of poor foaming due to damage of the aluminum foil tape, thereby affecting the refrigeration effect.

[0054] like Figures 5 to 7 As shown, in some embodiments of the present application, the annular pipe-straightening groove 31 is approximately located in the middle of the length direction of the pipe-straightening roller 30 , and it can be injection molded together with the pipe-straightening roller 30 .

[0055] In some embodiments of the present application, Figures 5 to 7 As shown, a plurality of recessed portions 33 are formed on the outer peripheral surface area 32 of the pipe-straightening roller on both sides of the annular pipe-straightening groove 31 , and the plurality of recessed portions 33 are arranged at intervals along the circumference of the outer peripheral surface area 32 of the pipe-straightening roller.

[0056] When the whole tube roller 30 rolls with the entire tooling and presses the aluminum foil tape onto the condenser 3, the plurality of recessed portions 33 can squeeze out the air between the tape and the whole tube roller 30 in time, so that the aluminum foil tape fits the condenser 3 and the surface of the box shell where the condenser 3 is located as closely as possible, thereby further improving the condenser coating quality.

[0057] In some embodiments of the present application, the recessed portion 33 is in a strip shape, that is, a strip-shaped groove. The strip-shaped recessed portion 33 extends in a direction parallel to the axial direction of the whole tube roller 30, and the recessed portions 33 on the outer peripheral surface area 32 of the whole tube roller on both sides of the annular whole tube groove 31 are arranged one by one opposite to each other.

[0058] By setting the recessed portion 33 as a strip-shaped recessed portion 33 extending in a direction parallel to the axial direction of the whole tube roller 30, since the axial direction of the whole tube roller 30 is parallel to the width direction of the aluminum foil tape, that is, perpendicular to the laminating direction of the aluminum foil tape, the air between the aluminum foil tape and the whole tube roller 30 can be quickly discharged along the width direction of the aluminum foil tape.

[0059] In some embodiments of the present application, the tape roller 20 is located between the whole tube roller 30 and the guide roller 40, and the tape roller 20 is located obliquely above the whole tube roller 30 to fully utilize the internal space of the shell 10; a guide component 50 is also provided in the shell 10, which is used to redirect the coating section 2-1 (i.e. the head section of the unwinding) of the tape roll 2 and lead it to the bottom of the whole tube roller 30, so that the aluminum foil tape can be smoothly guided to the bottom of the whole tube roller 30, so that the aluminum foil tape can be unwound in an orderly manner, which is conducive to further ensuring the coating quality.

[0060] In some embodiments of the present application, the guide component 50 is located below the tape roller 20 and between the full tube roller 30 and the guide roller 40, so that the aluminum foil tape does not interfere with the guide roller 40 when being unwound and drawn out.

[0061] The guide component 50 may be cylindrical, semi-cylindrical, or an outwardly convex arc-shaped guide plate, and no specific limitation is made here.

[0062] In some embodiments of the present application, reference Figures 8 to 11 , while combining Figures 1 to 4 A cutting knife 60 is provided at the front of the housing 10. In the embodiment of the present application, the end where the tube-straightening roller 30 is located is the front, and the end where the guide roller 40 is located is the rear. The cutting knife 60 is used to cut the aluminum foil tape. The cutting edge of the cutting knife 60 is exposed below the through-portion 11 so as to be able to contact the pasting section 2-1 of the tape roll 2. By providing the cutting knife 60, the condenser pasting tool 1 in the embodiment of the present application can not only have the functions of pasting and tube straightening, but also cut the aluminum foil tape at any time when needed, without the need for additional tool configuration, and is convenient to use.

[0063] The cutting knife 60 can be a serrated metal cutting knife, which is not specifically limited here. The cutting knife 60 is arranged at the front side of the whole tube roller 30, and is extended along the width direction of the aluminum foil tape. When cutting, the rear part of the condenser covering tool 1 is lifted to separate the guide roller 40 from the condenser tube 3, and the cutting knife 60 is pressed down to contact the covering section 2-1 of the tape roll 2 to cut it off. Fig.11 shown.

[0064] In some embodiments of the present application, Figures 8 to 10 As shown, the shell 10 includes a first shell part 12 and a second shell part 13. The first shell part 12 and the second shell part 13 are arranged opposite to each other and connected to each other as a whole, and the connection structure is a detachable connection structure, so that the first shell part 12 and the second shell part 13 can be easily disassembled, separated and connected, thereby facilitating the installation and replacement of various components inside the shell 10, such as replacing a new tape roll 2 after the tape roll 2 is used up, or replacing other components when they are damaged.

[0065] In some embodiments of the present application, a plurality of groups of mutually cooperating snap-fit ​​structures are arranged circumferentially on the mating surfaces of the first shell portion 12 and the second shell portion 13, and a detachable connection is achieved by snapping; of course, the first shell portion 12 and the second shell portion 13 may also be detachably connected by other detachable connection methods, such as a plurality of groups of mutually cooperating magnetic structures are arranged circumferentially on the mating surfaces of the two, and no specific limitation is made here.
