[0002] Most refrigerator cabinets choose galvanized sheet as the base material. Galvanized sheet has low cost and stable performance, which can meet the needs of mass production, making galvanized sheet more cost-effective in the manufacturing of household appliances such as refrigerator cabinets. In the process of galvanized sheet processing, processing equipment is usually used to process it.

[0003] Since the surface of the galvanized sheet may be bumped or deformed during the punching process, it needs to be straightened after punching. The existing straightening methods for galvanized sheets mostly use straightening machines. However, straightening machines are expensive, bulky and have high maintenance costs. Some small processing companies cannot afford their economic costs. At the same time, most traditional galvanized sheet processing devices do not have a straightening function, which brings inconvenience to the processing of galvanized sheets. Summary of the invention

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The embodiment of the present invention provides a galvanized sheet for a refrigeration cabinet, such as Figure 1-10 As shown, the production device of galvanized sheet for refrigeration cabinet includes: a workbench 1 and a support frame 2 and a stamping plate 4 installed on the workbench 1; a cylinder 3 fixedly installed on the support frame 2 for punching the galvanized sheet and a stamping part 5 detachably installed on the cylinder 3; a connecting plate 6 fixedly installed on one side of the support frame 2; a plurality of groups of straightening rollers 7 rotatably installed on the connecting plate 6 for straightening the galvanized sheet; and a driving mechanism arranged on the connecting plate 6 for driving the galvanized sheet to move.

[0025] In this embodiment, the driving mechanism drives the galvanized sheet to move to the right side so that it moves to the punching plate 4, and then the cylinder 3 drives the punching part 5 to descend to punch the galvanized sheet. After the punching is completed, the galvanized sheet continues to move (driven by the driving mechanism) to enter between multiple groups of straightening rollers 7. The straightening rollers 7 straighten the galvanized sheet through their rotation to correct the deformation or bump marks that may be generated during the punching process. When the galvanized sheet moves to the punching plate 4, its translation angle has been adjusted through the previous processing step, thereby ensuring that it moves smoothly and will not be skewed; By setting the straightening roller 7, the use of expensive straightening machines can be effectively avoided, reducing the economic cost of the processing enterprise, so that small processing enterprises can also afford the straightening work of galvanized sheets. By integrating the punching and straightening functions in the same device, the continuity and automation of the galvanized sheet processing process are achieved, and the production efficiency is improved. The stamping part 5 can be detachably installed, which is convenient for replacement according to different punching requirements. At the same time, the design of multiple sets of straightening rollers 7 also increases the flexibility and adaptability of the straightening process.

[0026] In a further preferred embodiment of the present invention, the driving mechanism includes: a group of driving rollers 8 rotatably mounted on the connecting plate 6 for driving the galvanized sheet to move; connecting gears 9 fixedly mounted on the rotating shafts of a group of driving rollers 8, respectively, and the two connecting gears 9 are meshed with each other; a first motor 10 fixedly mounted on one side of the connecting plate 6 for driving a group of driving rollers 8 to rotate, and the output shaft of the first motor 10 is fixedly connected to the rotating shaft of any one of the driving rollers 8; a connecting mechanism provided on a group of driving rollers 8 and a plurality of groups of straightening rollers 7 for synchronously driving a group of driving rollers 8 and a plurality of groups of straightening rollers 7 to rotate.

[0027] In this embodiment, when the first motor 10 is started, its rotational force is transmitted to the rotating shaft of the driving roller 8 fixedly connected thereto through the output shaft, thereby driving the driving roller 8 to rotate. Since the two connecting gears 9 are meshed, when one driving roller 8 rotates, it will drive the other driving roller 8 to rotate in the opposite direction, thereby realizing the clamping and moving operation of the galvanized sheet. When the driving roller 8 rotates, the connecting mechanism transmits the rotational force to multiple groups of straightening rollers 7, so that the straightening rollers 7 rotate synchronously, and the galvanized sheet after punching is straightened. The driving roller 8 is driven to rotate by the first motor 10, thereby realizing the automatic movement and straightening operation of the galvanized sheet, thereby improving the production efficiency. The rotational force of the driving roller 8 is transmitted to multiple groups of straightening rollers 7 through the connecting mechanism, so that the straightening rollers 7 rotate synchronously, and the galvanized sheet after punching is quickly and effectively straightened.

[0028] In a further preferred embodiment of the present invention, the connecting mechanism includes: a first sprocket 11 fixedly mounted on the rotating shafts of the driving roller 8 and the straightening roller 7 respectively; a first chain 12 mounted on a group of the first sprockets 11, the first chain 12 meshing with a group of the first sprockets 11; a limiting wheel 13 rotatably mounted on one side of the connecting plate 6 for limiting the first chain 12, the limiting wheel 13 meshing with the first chain 12.

[0029] In this embodiment, when the driving roller 8 rotates driven by the first motor 10, the first sprocket 11 on its rotating shaft also rotates. Since the first chain 12 is meshed with a group of first sprockets 11, the rotational force will be transmitted to the first sprocket 11 on the straightening roller 7 adjacent to the driving roller 8 through the first chain 12, thereby driving the straightening roller 7 to rotate. Subsequently, the rotational force will continue to be transmitted to other subsequent straightening rollers 7 through the first chain 12, so that all straightening rollers 7 rotate synchronously with the driving roller 8. The limiting wheel 13 plays a limiting and guiding role in the entire transmission process, ensuring that the first chain 12 can transmit the rotational force smoothly and accurately. Through the meshing transmission of the first sprocket 11 and the first chain 12, efficient transmission of rotational force is achieved, ensuring the synchronous rotation of the driving roller 8 and the straightening roller 7.

[0030] In a further preferred embodiment of the present invention, a photoelectric detection device 14 is installed on the support frame 2, and a support plate 15 for supporting the galvanized sheet is fixedly installed on the top of the workbench 1.

[0031] In this embodiment, when the galvanized sheet is placed on the support plate 15 and slides along it to the vicinity of the stamping plate 4, the photoelectric detection device 14 will emit a light beam and receive the reflected light signal to determine the position of the galvanized sheet. According to the preset punching spacing and the position information of the galvanized sheet, the control system will synchronously control the action of the cylinder 3 so that the stamping part 5 can punch the galvanized sheet at the accurate position. With the support of the support plate 15, the galvanized sheet can slide more easily along the direction of the stamping plate 4 until it enters the multiple sets of straightening rollers 7 for straightening operations. The design of the support plate 15 ensures the stability and accuracy of the galvanized sheet during movement, avoiding punching errors caused by shaking or deviation.

[0032] In a further preferred embodiment of the present invention, a support plate is fixedly installed in the support frame 2, and a plurality of electric telescopic rods 16 are fixedly installed at the bottom of the support plate, and guide wheels 17 for guiding the galvanized sheet are installed on the plurality of electric telescopic rods 16.

[0033] In this embodiment, when the electric telescopic rod 16 is extended, the guide wheel 17 installed at the bottom thereof will be close to and contact the galvanized sheet, playing a guiding and limiting role. During the movement of the galvanized sheet, the guide wheel 17 will roll and contact the side or bottom of the galvanized sheet to ensure that it moves smoothly along a predetermined path. The design of the guide wheel 17 also helps to prevent the galvanized sheet from warping on one side due to uneven force during movement, thereby ensuring the quality and efficiency of subsequent straightening operations. The limiting and guiding of the guide wheel 17 ensures the stability and accuracy of the galvanized sheet during movement, thereby improving the guiding accuracy.

[0034] In a further preferred embodiment of the present invention, a collection box 18 for collecting waste is provided below the workbench 1, and a hand collection bucket 19 is fixedly installed on the top of the workbench 1. The collection bucket 19 is located below the stamping plate 4 and is used to receive waste.

[0035] In this embodiment, during the stamping operation, the stamping part 5 stamps the galvanized sheet on the stamping plate 4 to generate waste, which falls into the collecting bucket 19 located below the stamping plate 4. The collecting bucket 19 guides the waste to slide down and discharges it into the collecting box 18 below the workbench 1. The collecting box 18 collects and stores the waste until the operation is completed or its capacity limit is reached. Through the combined use of the collecting bucket 19 and the collecting box 18, automatic collection and storage of waste is achieved, reducing the time and labor cost of manual waste cleaning, and improving work efficiency. The waste is collected and stored in the collecting box 18 in a timely manner, avoiding the accumulation and scattering of waste on the workbench, keeping the working environment clean and orderly, and timely collection of waste helps prevent it from accumulating around the equipment or entering the equipment, thereby avoiding equipment failure or damage caused by waste.

[0036] In a further preferred embodiment of the present invention, a T-plate 20 is fixedly installed in the collection box 18, and the T-plate 20 separates the collection box 18 into an operation chamber and two collection chambers, and a collection box 21 is provided in each of the two collection chambers. A connecting spring 22 is installed in the operation chamber, and the connecting spring 22 passes through the T-plate 20, and a placement plate 23 for placing the collection box 21 is fixedly installed on the top of the connecting spring 22, and magnet bars 24 are fixedly installed on the placement plate 23 and the collection box 21, and the two magnet bars 24 are adsorbed to each other.

[0037] In this embodiment, when the collecting hopper 19 discharges the waste into the collecting box 21, as the weight of the waste increases, the collecting box 21 will drop and compress the connecting spring 22 at the same time. When the weight of the waste in the collecting box 21 reaches the preset moving weight, the connecting spring 22 is compressed to the limit. At this time, the placing plate 23 contacts the bottom of the collecting chamber. When the waste in a collecting box 21 reaches the maximum capacity, the collecting box 18 is moved by the moving mechanism to align the other empty collecting chamber with the discharge port of the collecting hopper 19 to continue the waste collection operation. At the same time, the operator can remove the collecting box 21 full of waste from the placing plate 23 to clean the waste and replace it with a new collecting box 21. Through the design of the connecting spring 22 and the magnet bar 24, the automatic descent and stable placement of the collecting box 21 are realized without manual intervention, thereby improving the degree of automation.

[0038] In a further preferred embodiment of the present invention, an annular guide bucket 32 ​​is fixedly installed in the collection chamber, and the annular guide bucket 32 ​​is located above the collection box 21. Limiting screws 36 for limiting the placement plate 23 are rotatably installed on both sides of the collection box 18.

[0039] The setting of the limit screw 36 prevents the safety hazard caused by the rapid release of the elastic force of the connecting spring 22 after the collection box 21 is taken out, thereby enhancing the safety of operation.

[0040] In a further preferred embodiment of the present invention, a protective cover 37 for protecting the driving mechanism is fixedly mounted on one side of the connecting plate 6, and the protective cover 37 is disposed on the driving mechanism.

[0041] In this embodiment, by providing the protective cover 37, the driving mechanism can be effectively protected to ensure that workers and external impurities will not come into contact with it, thereby improving the safety of the device.

[0042] The present invention also provides a production process of a galvanized sheet for a refrigeration cabinet, comprising the following steps: Step 1: Select high-quality galvanized steel plates that meet the requirements of refrigeration cabinets as raw materials, and conduct quality inspections on the raw materials to ensure that they meet production standards and customer needs.

[0043] Step 2: The galvanized steel sheet is placed in the stamping area on the workbench 1, and is precisely positioned and fixed by the driving roller 8, the support frame 2, and the electric telescopic rod 16 and the guide wheel 17 on the support plate to ensure stability and accuracy during the stamping process; Then start the cylinder 3 to make the stamping part 5 punch the galvanized steel plate on the stamping plate 4. The waste generated during the stamping process falls into the collection box 21 in the collection box 18 through the collecting bucket 19. The annular guide bucket 32 ​​guides the waste to fall accurately. At the same time, the spring 22 and the limit screw 36 are connected to ensure the smooth and safe collection process.

[0044] Step 3: The galvanized sheet after punching is straightened by the straightening roller 7. The straightening roller 7 straightens the galvanized sheet by its rotation to correct the deformation or bump marks that may be produced during the punching process. The straightened galvanized sheet is then subjected to quality inspection, including appearance inspection, size measurement and performance testing, to ensure product quality.

[0045] Step 4: When the collection box 21 is fully loaded, the limiting screw 36 is rotated to limit it, and then the collection box 21 is taken out to clean and process the waste, and the cleaned empty collection box 21 is placed back on the placement plate 23, the limiting screw 36 is loosened, the connecting spring 22 restores the elastic force, and the placement plate 23 and the collection box 21 are pushed back to their original positions, preparing for the next round of waste collection.

[0046] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a switch device 30 is fixedly installed at the bottom of the operating chamber, a touch rod 31 is fixedly installed at the bottom of the placement plate 23, and the touch rod 31 is arranged at the same level as the switch device 30. A group of moving mechanisms for moving the collection box 18 are arranged at the bottom of the workbench 1, and the moving mechanisms include: a one-way screw 25 rotatably installed at the bottom of the workbench 1; a slider 26 threadedly sleeved on the one-way screw 25 for driving the collection box 18 to move, and the slider 26 is fixedly connected to the collection box 18; a second sprocket 27 sleeved on the one-way screw 25, and a second chain 28 is sleeved on the second sprocket 27; a second motor 29 fixedly installed at the bottom of the workbench 1, and the output shaft of the second motor 29 is fixedly connected to the one-way screw 25.

[0047] In this embodiment, when the collection box 21 slides down to contact the bottom of the collection chamber due to the increase in the weight of the waste, the touch rod 31 also drops down. The touch rod 31 is arranged at the same level as the switch device 30 fixedly installed at the bottom of the operation chamber. Therefore, when the touch rod 31 drops to the bottom, the switch device 30 is triggered. After the switch device 30 is triggered, the second motor 29 is automatically started. After the second motor 29 is started, its output shaft drives the fixedly connected one-way screw 25 to rotate. When the one-way screw 25 rotates, the slider 26 slides along the length direction of the one-way screw 25. In order to realize the synchronous operation of a group of moving mechanisms, a second sprocket 27 is sleeved on the one-way screw 25. The second sprockets 27 are connected by a second chain 28. In this way, when one one-way screw 25 rotates, the second sprocket 27 and the second chain 28 drive the other one-way screw 25 to rotate synchronously. The sliding of the slider 26 drives the collection box 18 to move, so that the collection box 21 full of waste is away from the bottom of the collection bucket 19, and the empty collection box 2 is moved. 1 moves to the bottom of the collecting bucket 19 to prepare for receiving new waste. Through the cooperation of the switch device 30, the touch rod 31 and the moving mechanism, the automatic detection of the full load of the collecting box 21 and the automatic movement of the collecting box 18 are realized without manual intervention, which improves the degree of automation. When a collecting box 21 is full, the moving mechanism can quickly move it away and align the empty collecting box 21 with the bottom of the collecting bucket 19, ensuring the continuity of waste collection and improving the collection efficiency. The one-way screw 25 in a group of moving mechanisms realizes synchronous operation through the second sprocket 27 and the second chain 28, so that the entire moving mechanism has a compact structure and stable operation.

[0048] In another embodiment of the present invention, a guide cylinder 34 is fixedly mounted on the T-plate 20 , and a pull rope 35 is fixedly mounted on the bottom of the placement plate 23 . The pull rope 35 passes through the guide cylinder 34 and extends into the operating cavity.

[0049] In this embodiment, when the collection box 21 filled with waste is cleaned, the placement plate 23 needs to be reset. The operator first pulls the pull rope 35 to make it taut. At this time, the connecting spring 22 is still in a compressed state, and the placement plate 23 is limited by the limit screw 36. Then, the operator rotates the limit screw 36 to make it rotate away from the placement plate 23 to release the limit on the placement plate 23. After the limit is released, the operator slowly releases the pull rope 35. At this time, the connecting spring 22 begins to release the elastic force, pushing the placement plate 23 up. Due to the existence of the pull rope 35, the operator can control the release of the pull rope 35. 5, thereby controlling the rising speed of the placement plate 23, avoiding the connection spring 22 directly releasing the elastic force to cause damage to the collection box 21; by pulling the pull rope 35 and releasing it slowly, the rising speed of the placement plate 23 can be controlled, avoiding the impact caused by the connection spring 22 directly releasing the elastic force, and effectively protecting the collection box 21 from damage; the setting of the pull rope 35 allows the operator to perform a reset operation outside the operating chamber, avoiding the safety risks that may be caused by direct contact with the inside of the machine; through the cooperation of the pull rope 35 and the limit screw 36, the reset operation process of the placement plate 23 is simplified, and the work efficiency is improved.

[0050] In another embodiment of the present invention, the workbench 1 is provided with two groups of limiting mechanisms for preventing the galvanized sheet from shifting, and the limiting mechanisms include: a connecting box 38 fixedly installed on the top of the workbench 1; a group of discs 39 rotatably installed in the connecting box 38, and a limiting seat 40 is installed on the disc 39; a guide rod 41 fixedly installed in the connecting box 38; a connecting frame 43 slidably mounted on the guide rod 41, and the connecting frame 43 is connected to the limiting seat 40; an adjustment plate 42 mounted on the connecting frame 43 for limiting the galvanized sheet; a round rod 44 rotatably installed in the connecting box 38, and the round rod 44 is located on one side of the disc 39; a third sprocket 45 fixedly mounted on the rotating shafts of the round rod 44 and the disc 39, respectively, and a group of the third sprockets 45 are provided with a third chain 46; a linkage mechanism provided on the connecting box 38 and the connecting gear 9 for synchronously driving the connecting gear 9 and the disc 39.

[0051] In this embodiment, the operation of the driving mechanism drives the linkage mechanism to operate synchronously at the same time, driving the disc 39 to rotate. Since the limit seat 40 is away from the center position of the disc 39, when the disc 39 rotates, the limit seat 40 will move along the connecting frame 43, thereby driving the connecting frame 43 to move left and right along the guide rod 41. The movement of the connecting frame 43 will drive the adjustment plate 42 to slide left and right synchronously, so that a group of adjustment plates 42 slide relatively, and the position of the galvanized sheet is limited. In this way, the galvanized sheet will not deviate when moving on the straightening roller 7, thereby ensuring the accuracy of its position. Through the setting of the linkage mechanism, the synchronous operation of the driving mechanism and the limit mechanism is realized, thereby ensuring the position accuracy of the galvanized sheet during the straightening process. The design of the limit mechanism is reasonable, and the connection and transmission methods between the components are clear, thereby enhancing the stability and reliability of the equipment. Through the limiting effect of the adjustment plate 42, the displacement and damage of the galvanized sheet during the straightening process are avoided, thereby protecting the quality of the galvanized sheet.

[0052] In another embodiment of the present invention, the linkage mechanism includes: a connecting rod 47 rotatably installed on one side of the connecting box 38, one end of the connecting rod 47 extends out of the connecting plate 6; a first bevel gear 48 fixedly mounted on the rotating shaft of the disc 39 and the connecting rod 47, and the two first bevel gears 48 are meshed with each other; a fourth sprocket 50 fixedly mounted on the connecting rod 47, and a fourth chain 51 is mounted on the fourth sprocket 50; a driven gear 53 rotatably installed on one side of the connecting plate 6, and the driven gear 53 is meshed with the connecting gear 9; a rotating rod 52 rotatably installed on one side of the connecting plate 6; second bevel gears 54 are fixedly mounted on both ends of the rotating rod 52, the connecting rod 47 and the rotating shafts of the driven gear 53, and two groups of the second bevel gears 54 are meshed with each other.

[0053] When the second bevel gear 54 is driven by the driven gear 53, the driven gear 53 drives the second bevel gear 54 to rotate. The second bevel gear 54 transmits the rotational force to the rotating rod 52, so that the rotating rod 52 rotates. When the rotating rod 52 rotates, it drives the first bevel gear 48 to rotate, so that the driving disk 39 rotates synchronously, thereby realizing the driving operation of the limiting mechanism. Since two sets of limiting mechanisms are provided on the workbench 1, the two sets of limiting mechanisms include two rotating rods 52. When the second bevel gear 54 drives the rotating rod 52 to rotate, the rotating rod 52 drives the fourth sprocket 50 to rotate, so that the fourth sprocket 50 drives the fourth chain 51 to rotate simultaneously, so that the two rotating rods 52 rotate simultaneously, realizing the synchronous operation of the two sets of limiting mechanisms. The design of the first bevel gear 48, the second bevel gear 54, the fourth sprocket 50 and the fourth chain 51 ensures the synchronous rotation of the two sets of limiting mechanisms, and improves the stability and coordination of the device.

[0054] In summary, compared with related technologies, this device integrates punching and straightening functions in the same device, which can realize automatic punching and efficient straightening operations of galvanized sheets, bringing more convenience and benefits to the processing of galvanized sheets.
