Description

Technical Field

[0001] The invention relates to the technical field of display cabinets, and in particular to a one-step forming structure of an inner liner and an evaporator of a vertical display cabinet and a preparation method thereof. Background Art

[0002] In the current field of refrigeration equipment technology, vertical display cabinets are important equipment for commercial display and storage. The stability of the inner tank structure and the coating effect of the evaporator have a vital impact on the performance of the display cabinet. The inner tank of a traditional vertical display cabinet usually adopts a splicing and pressing structure. This structure requires a lot of manual operation during the manufacturing process, which not only has low production efficiency, but also is prone to splicing misalignment problems. At the same time, the evaporator needs to be manually coated on the inner tank after molding. This operation method is not only time-consuming and labor-intensive, but also difficult to ensure that the evaporator and the inner tank are tightly fitted, resulting in uneven temperature distribution inside the display cabinet, affecting the quality of the goods stored in the display cabinet.

[0003] Specifically, the splicing and pressing structure of the traditional vertical display cabinet liner has the following defects: First, due to the uncontrollability of manual operation, gaps and misalignments are prone to occur at the splicing, which not only affects the overall strength of the liner, but may also cause cold air leakage and outside air to enter, thereby reducing the insulation performance and refrigeration effect of the display cabinet. Secondly, the evaporator coating process also relies on manual operation, and it is difficult to ensure the precise alignment and tight fit between the evaporator and the liner. Inadequate coating of the evaporator will lead to uneven cooling, resulting in temperature differences inside the display cabinet, which in turn affects the storage quality of the goods and customer satisfaction. Summary of the invention

[0004] The purpose of the present invention is to provide a one-piece molding structure of a vertical display cabinet liner and an evaporator and a preparation method thereof, so as to solve the problem that the traditional vertical display cabinet liner proposed in the above background technology usually adopts a splicing and pressing structure, which requires a lot of manual operation during the manufacturing process, not only has low production efficiency, but also is prone to splicing misalignment problems.

[0005] To achieve the above-mentioned purpose, the present invention provides a one-time molding structure of an inner liner and an evaporator of a vertical display cabinet, including an inner liner side, a liner top is installed at the upper end of the inner liner side, and a liner bottom is installed at the lower end of the inner liner side. The inner liner side is an integrally formed U-shaped structure, and a plurality of reinforcing irons are installed on the outer surfaces of both sides of the inner liner side. The outer wall of the inner liner side is covered with an evaporator. The evaporator is a U-shaped structure as a whole and is attached to the outer surface of the inner liner side. Punching holes are provided on the inner liner side and the reinforcing iron for installing shelves.

[0006] As a preferred embodiment of the present invention, the reinforcing iron is fixed to the surface of the inner liner by riveting.

[0007] As a preferred embodiment of the present invention, the outer side of the reinforcement iron is covered with a milky white film.

[0008] As a preferred embodiment of the present invention, the connections between the upper and lower sides of the inner liner and the bottom and top of the liner are sealed by adhesive tape.

[0009] As a preferred solution of the present invention, the number of the reinforcing irons is four, and they are vertically arranged on the outer surfaces of both sides of the inner liner.

[0010] As a preferred solution of the present invention, the evaporator comprises a coil structure, and the spacing between the coils is 60 mm.

[0011] The present invention also provides a method for preparing a one-step forming structure of a vertical display cabinet liner and an evaporator, which is used for the one-step forming structure of a vertical display cabinet liner and an evaporator, and comprises the following steps: S1. The aluminum inner liner side cut-to-size material is put on line and processed by punching, punching and other processes to facilitate subsequent assembly; S2, using a flexible robot arm to place the reinforcement iron at a designated position on the inner liner side, and riveting the reinforcement iron to the inner liner side; S3. Punch holes on the inner tank side to ensure that the inner tank holes are concentric with the reinforcement iron holes to facilitate subsequent fixing of the shelf support strips; S4, by pasting the milky white film on the outside of the reinforcement iron, the four reinforcement irons are sealed in place at one time, effectively preventing the foaming material from overflowing from the hole; S5. Accurately position the coils of the evaporator with a spacing of 60 mm on the inner tank side, and use the servo automatic laminating machine and aluminum foil to seal the evaporator in place, ensuring that the evaporator is evenly arranged and well sealed; S6, sending the inner liner side and the evaporator to the U-folding forming equipment through a conveyor belt to achieve one-time U-folding forming of the inner liner side and the evaporator; S7. Assemble the top and bottom of the bladder onto the inner side of the bladder and seal them with tape.

[0012] As a preferred embodiment of the present invention, in step S2, the reinforcing iron is firmly connected to the inner liner side by a rivet-free riveting technology, which causes the material to undergo plastic deformation through mechanical pressure to form an inseparable connection, thereby improving production efficiency and product aesthetics.

[0013] As a preferred embodiment of the present invention, in step S4, the milky white film is applied by an automatic laminating machine to ensure that the milky white film is evenly and bubble-freely applied on the reinforcing iron, effectively preventing the foaming material from overflowing and enhancing the sealing effect.

[0014] As a preferred embodiment of the present invention, in step S6, the bladder top and bladder bottom are aligned with the notch at the top of the inner bladder side through the folded edge on one side, so as to achieve precise alignment of the bladder top and the inner bladder side.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The one-step forming structure of the liner and evaporator of the vertical display cabinet and the preparation method thereof, through the automated production line and one-step forming technology, greatly reduces manual operation, improves production efficiency, and reduces manufacturing costs. Compared with the traditional manual splicing and pasting method, the present invention can complete the assembly of the liner and the evaporator more quickly and accurately, thereby shortening the production cycle and reducing labor costs.

[0016] 2. The one-time forming structure of the liner and evaporator of the vertical display cabinet and its preparation method adopts one-time forming technology, so that the liner side and the evaporator can fit closely together, avoiding the gap and misalignment problems in the traditional splicing structure. At the same time, through rivet-free riveting technology and automatic laminating technology, the connection between the reinforcement iron and the liner side and the evaporator and the liner side is more firm, which improves the overall strength and stability of the liner.

[0017] 3. In the one-step forming structure of the liner and evaporator of the vertical display cabinet and the preparation method thereof, due to the close fit between the liner structure and the evaporator, the present invention effectively prevents the leakage of cold air and the entry of outside air, thereby improving the thermal insulation performance and refrigeration effect of the display cabinet. This makes the temperature distribution inside the display cabinet more uniform, the quality of goods storage is guaranteed, and customer satisfaction is improved.

[0018] 4. The one-step forming structure of the vertical display cabinet liner and the evaporator and its preparation method adopt rivet-free riveting technology and milky white film coating technology, which makes the connection between the reinforcement iron and the liner side smoother and more beautiful, and enhances the sealing effect. In addition, the application of one-step forming technology and automated production line also improves the durability and reliability of the product and extends the service life of the display cabinet.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention provides a one-step forming structure of a vertical display cabinet liner and an evaporator, such as Figure 1-Figure 5 As shown, it includes an inner liner side 1, a liner top 2 is installed at the upper end of the inner liner side 1, a liner bottom 3 is installed at the lower end of the inner liner side 1, the inner liner side 1 is an integrally formed U-shaped structure, and a plurality of reinforcing irons 4 are installed on the outer surfaces of both sides of the inner liner side 1. The outer wall of the inner liner side 1 is covered with an evaporator 5, and the evaporator 5 is a U-shaped structure as a whole, which is attached to the outer surface of the inner liner side 1. Punching holes are provided on the inner liner side 1 and the reinforcing iron 4 for installing shelves. The inner liner side 1 adopts an integrally formed U-shaped structure, which eliminates the gaps and dislocations in the traditional splicing structure and improves the overall strength and stability of the inner liner. At the same time, the evaporator 5 is also designed as a U-shaped structure and fits tightly on the outer surface of the inner liner side 1 to ensure the uniform distribution of the cooling effect. A plurality of reinforcing irons 4 are installed on the outer surfaces of both sides of the inner liner side 1. These reinforcing irons not only enhance the load-bearing capacity and anti-deformation ability of the inner liner, but also facilitate the installation of shelves through the punching holes thereon, thereby increasing the practicality and flexibility of the display cabinet. The evaporator 5 fits tightly against the outer wall of the inner tank side 1, reducing the possibility of cold air leakage and outside air intrusion, thereby improving the thermal insulation and cooling effect of the display cabinet. This tight-fitting design also ensures the uniformity of temperature distribution inside the display cabinet, which helps to maintain the quality of the goods. Punching holes are provided on the inner tank side 1 and the reinforcement iron 4, which are not only used to install the shelf, but also facilitate subsequent maintenance and repair work. At the same time, the one-time molding structural design also simplifies the assembly process of the display cabinet and improves production efficiency.

[0022] In this embodiment, the reinforcing iron 4 is fixed to the surface of the inner liner side 1 by riveting. Through riveting, a firm connection is formed between the reinforcing iron 4 and the inner liner side 1, which significantly enhances the structural strength and stability of the inner liner side 1. This connection method can not only effectively resist external impact, but also prevent loosening or falling off due to long-term use, thereby extending the service life of the display cabinet.

[0023] Specifically, the outer side of the reinforcing iron 4 is covered with a milky film 41. The covering of the milky film 41 provides an additional protective layer for the reinforcing iron 4, effectively preventing the reinforcing iron 4 from being corroded or damaged during use. At the same time, the milky film 41 also has good sealing performance, which can prevent impurities such as foaming materials from overflowing from the gap between the reinforcing iron 4 and the inner liner side 1, keeping the interior of the display cabinet clean and tidy.

[0024] Furthermore, the connection between the upper and lower sides of the inner liner side 1 and the liner bottom 3 and the liner top 2 is sealed by adhesive tape. The adhesive tape sealing ensures that the connection between the inner liner side 1 and the liner bottom 3 and the liner top 2 is tight and gap-free, thereby improving the thermal insulation performance and refrigeration effect of the display cabinet. This sealing method is not only simple and easy to operate, but also can effectively prevent cold air leakage and outside air from entering, maintaining the stability and uniformity of the temperature inside the display cabinet.

[0025] Furthermore, there are four reinforcing irons 4, which are arranged vertically on the outer surfaces of both sides of the inner liner side 1. The vertical arrangement of the four reinforcing irons 4 further enhances the load-bearing capacity and anti-deformation ability of the inner liner side 1. This layout not only allows the inner liner side 1 to remain stable when subjected to external forces, but also improves the overall aesthetics and practicality of the display cabinet. At the same time, the design of the four reinforcing irons 4 is also easy to install and disassemble, which facilitates subsequent maintenance and overhaul work.

[0026] Furthermore, the evaporator 5 includes a coil structure, and the spacing between the coils is 60 mm. The coil structure design of the evaporator 5 ensures uniform distribution of the cooling effect. The 60 mm spacing setting not only ensures the close fit between the evaporator 5 and the inner tank side 1, but also avoids poor cooling effect due to too small spacing or waste of cold air due to too large spacing. This design allows the internal temperature of the display cabinet to remain stable and uniform, which helps to maintain the quality of the goods and extend their shelf life.

[0027] The present invention also provides a method for preparing a one-step forming structure of a vertical display cabinet liner and an evaporator, which is used for the one-step forming structure of a vertical display cabinet liner and an evaporator, and comprises the following steps: S1. The aluminum inner liner side 1 is put on line and processed by punching, punching and other processes to facilitate subsequent assembly; S2, using a flexible robot arm to place the reinforcement iron 4 at a designated position on the inner liner side 1, and riveting the reinforcement iron 4 to the inner liner side 1; S3, punch holes on the inner tank side 1, ensuring that the inner tank holes are concentric with the reinforcing iron holes 4, so as to facilitate the subsequent fixing of the shelf support strips; S4, by pasting the milky white film 41 on the outside of the reinforcing iron 4, the four reinforcing irons 4 are sealed in place at one time, effectively preventing the foaming material from overflowing from the hole; S5, accurately position the coils of the evaporator 5 with a spacing of 60 mm on the inner tank side 1, and use the servo automatic laminating machine and aluminum foil to seal the evaporator 5 in place, ensuring that the evaporator 5 is evenly arranged and well sealed; S6, sending the inner liner side 1 and the evaporator 5 to the U-folding forming device through a conveyor belt to achieve one-time U-folding forming of the inner liner side 1 and the evaporator 5; S7, assemble the bladder top 2 and the bladder bottom 3 on the inner bladder side 1, and use tape to seal them.

[0028] Furthermore, in step S2, the reinforcing iron 4 is firmly connected to the inner liner side 1 by using a rivet-free riveting technology. This technology causes the material to undergo plastic deformation through mechanical pressure to form an inseparable connection, thereby improving production efficiency and product aesthetics.

[0029] Furthermore, in step S4, the milky white film 41 is applied by an automatic laminating machine to ensure that the milky white film 41 is evenly and bubble-freely applied to the reinforcing iron 4, thereby effectively preventing the foaming material from overflowing and enhancing the sealing effect.

[0030] Furthermore, in step S6, the bladder top 2 and the bladder bottom 3 are aligned with the notch at the top of the inner bladder side 1 through the folded edge on one side, so as to achieve precise alignment of the bladder top 2 and the inner bladder side 1.

[0031] By bringing the cut-to-length aluminum liner side 1 material online and processing it through processes such as punching and punching, the initial forming of the liner side 1 is achieved, laying the foundation for subsequent assembly.

[0032] The use of flexible robot arms for placement and riveting of the reinforcement iron 4 and the application of the milky white film 41 improves production efficiency and precision and reduces manual operation errors and labor intensity. The use of rivet-free riveting technology to firmly connect the reinforcement iron 4 to the inner liner side 1 not only improves the connection strength, but also avoids the appearance damage that may be caused by traditional riveting methods, thereby improving the aesthetics of the product. The smooth, bubble-free application of the milky white film 41 effectively prevents the foaming material from overflowing, while enhancing the sealing effect, making the interior of the display cabinet more tidy and beautiful.

[0033] Punching holes on the inner tank side 1 and ensuring that the inner tank holes are concentric with the reinforcing iron 4 holes facilitates the subsequent fixing of the shelf support strips and also ensures the stability and accuracy of the shelf installation. The coil of the evaporator 5 is precisely positioned on the inner tank side 1 and sealed using a servo automatic laminating machine and aluminum foil, ensuring that the evaporator 5 is evenly arranged and well sealed, thereby achieving uniform cooling inside the display cabinet.

[0034] The inner tank side 1 and the evaporator 5 are sent to the U-folding forming device through a conveyor belt, which realizes one-time U-folding forming, simplifies the production process and improves production efficiency. The tank top 2 and the tank bottom 3 are aligned with the notch at the top of the inner tank side 1 through the folded edge on one side, achieving precise alignment, and are sealed with tape to ensure the thermal insulation performance and cooling effect of the display cabinet.

[0035] In summary, the preparation method of the one-piece molding structure of the vertical display cabinet liner and the evaporator provided by the present invention significantly improves the production efficiency and product quality of the display cabinet through technical means such as efficient automated production, firm connection and improved aesthetics, precise alignment and uniform cooling, and one-piece molding and sealing processing, and meets the diverse needs of commercial display and storage.
