Description

Technical Field

[0001] The invention relates to the field of refrigerator liner processing, in particular to equipment capable of processing medical refrigerator liner enclosures. Background Art

[0002] Medical refrigerators are specialized refrigeration equipment designed to store and protect specific medical items, including drugs, vaccines, enzymes, hormones, stem cells, platelets, semen, transplanted skin, animal tissue samples, extracted RNA, gene libraries, and some important biological and chemical reagents.

[0003] Medical refrigerators are usually equipped with inner liner panels to form a relatively independent and stable low-temperature environment inside the medical refrigerator to prevent external heat from invading and cold air from leaking out. At the same time, the inner liner panels serve as the inner wall of the medical refrigerator, which can prevent stored medicines, reagents, biological samples, etc. from directly contacting the outer shell or refrigeration components of the refrigerator to prevent items from being damaged or contaminated. It also helps the circulation and distribution of cold air inside the refrigerator, making the temperature inside the cabinet more uniform, improving the refrigeration effect, and ensuring that the stored items are within an appropriate temperature range. The smooth surface of the inner liner panels is not easy to absorb dust and bacteria, which makes it convenient for staff to regularly clean and disinfect the inside of the refrigerator to maintain good sanitary conditions and meet the requirements of the medical environment.

[0004] When processing the inner liner panels of medical refrigerators, the selected raw materials such as stainless steel plates, aluminum plates or engineering plastic plates are usually cut into suitable plates by shearing machines and other equipment. The cut plates are then bent or stamped by bending or stamping mechanisms to form the required specific shape structure. Finally, the bent or stamped inner liner panels are spliced and installed on the inner wall of the medical refrigerator. The splicing method is generally welding or riveting.

[0005] However, the existing bending or punching mechanism for the inner liner panel is generally only capable of bending or punching once. If two bending or punching processes are required, the sheet material after the first bending or punching needs to be cut first, and then re-loaded before the second processing, which greatly reduces the processing efficiency. In addition, when installing the inner liner panel of the existing medical refrigerator, whether it is a regular or irregular inner wall, it is usually spliced by multiple inner liner panels. This not only reduces the installation efficiency, but also causes the splicing seams to crack easily in the later stage due to the increase in splicing seams, reducing the overall sealing and service life of the inner liner panel. At the same time, the presence of too many splicing seams also reduces the smoothness of the interior of the medical refrigerator. Therefore, a medical refrigerator inner liner panel processing device is proposed. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the present invention proposes a processing device for the inner liner apron of a medical refrigerator, which can bend the inner liner apron once or twice, facilitating the processing operation, effectively improving the processing efficiency, having good processing integrity, facilitating the installation of the inner liner apron of a medical refrigerator with regular inner walls, increasing the service life, reducing the generation of splicing seams, and improving the smoothness of the interior of the medical refrigerator at the same time.

A stamping assembly is arranged on the slide frame, and the stamping assembly is used to cooperate with the molding frame and the pressing inclined block to perform stamping processing on the inner liner apron blank. An adjusting assembly for distance adjustment is arranged between the upper top plate and the lower top plate.

[0010] Preferably, guide rails are connected to both sides of the processing frame, and both sides of the lower top plate are respectively slidably connected within the guide rails on both sides. Guide rods are symmetrically connected to both sides of the processing frame, and the slide frames are slidably sleeved on the outer sides of the guide rods.

[0011] Preferably, a plurality of square sliding cylinders are arrayedly connected to the upper end surface of the lower top plate, and a plurality of square rods are arrayedly connected to the lower end surface of the upper top plate. The lower ends of the square rods are limited and slidably sleeved within the square sliding cylinders.

[0012] Preferably, a plurality of collar rings are connected to the mutually adjacent side surfaces of the lower top plate and the upper top plate. A first slide rod is slidably sleeved within each collar ring, and the end of the first slide rod away from the lower top plate or the upper top plate is connected to the molding frame.

[0013] Preferably, limiting sleeves are connected to the molding frames on both sides of the lower top plate, and limiting sleeve rods are connected to the molding frames on both sides of the upper top plate. The lower ends of the limiting sleeve rods are slidably sleeved within the limiting sleeves.

[0014] Preferably, limiting blocks are connected to the forming frames on both sides of the lower top plate. The rotating plates are inclinedly limited by the limiting blocks on their respective sides. A second sliding rod is connected inside the rotating frame. The extrusion inclined block is slidably sleeved outside the second sliding rod. A first spring sleeved outside the second sliding rod is connected between the extrusion inclined block and the rotating frame.

[0015] Preferably, third sliding rods are connected to the sides of the lower top plate and the upper top plate where the forming frames are close to each other. A slider is slidably sleeved on the outer side of each third sliding rod. A second spring sleeved on the outer side of the third sliding rod is connected between the slider and the third sliding rod. An expansion rod is connected between the adjacent upper and lower sliders. The pulling plate is connected to the slider sliding on the forming frames on both sides of the lower top plate.

[0016] Preferably, the stamping assembly includes a second telescopic member and an extrusion frame. The second telescopic member is installed on the sliding frame. The extrusion frame is connected to the upper end of the second telescopic member. An opening for the extrusion frame to penetrate is formed on the processing frame. The extrusion frame is arranged on the side where the two forming frames are far away from each other and cooperates with the side surface of the forming frame. The upper end of the extrusion frame is in sliding contact with the inclined surface of the extrusion inclined block.

[0017] Preferably, the adjustment assembly includes a threaded cylinder and a screw rod. The threaded cylinder is rotatably connected to the upper end of the lower top plate. The screw rod is connected to the lower end of the upper top plate. The lower end of the screw rod is threadedly sleeved inside the threaded cylinder.

[0018] Preferably, side plates are connected to both sides of the processing frame. A fourth sliding rod is slidably sleeved through the side plates. A positioning plate is connected to the fourth sliding rod. A lead screw threadedly sleeved with the side plate is rotatably connected to the positioning plate.

[0019] The beneficial effects of the present invention are as follows:

[0020] Through synchronously controlling the operation of the third telescopic members on both sides, the technical solution of the present invention can drive the sliding frames and the forming frames on both sides to approach or move away from each other. At the same time, by rotating the threaded cylinder, the screw rod can be driven to slide up and down inside it, adjusting the distance between the lower top plate and the upper top plate. Finally, the distance between the mutually far - away surfaces of the two formed plates is the size for the first bending of the inner liner enclosure blank, and the distance between the mutually far - away surfaces of the upper top plate and the lower top plate is the size for the second bending of the inner liner enclosure blank. Such adjustment facilitates flexible processing of inner liner enclosures of various sizes.

[0021] 2. The technical solution of the present invention drives the extrusion frame to move upward by the telescopic part 2, so that the inner liner enclosure placed between the processing frame and the lower top plate can be bent once. At the same time, when loading before processing, the spacing between the positioning plates on both sides can be adjusted by rotating the screw rods on both sides, which is convenient for straightening the inner liner enclosure front and back. The telescopic part 2 and the telescopic part 3 can also be controlled to operate so that the extrusion frame can pass through the opening and slightly protrude from the inner liner enclosure blank on the processing frame, and then drive the extrusion frames on both sides to approach each other to drive the inner liner enclosure blank to be centered on the left and right, and then drive the lower top plate to move downward by the telescopic part 1 to press the inner liner enclosure firmly, so that the inner liner enclosure blank can be conveniently placed in the middle of the processing frame, and finally the extrusion frame can be controlled to readjust to the bottom of the inner liner enclosure blank to facilitate subsequent bending processing;

[0022] 3. The technical solution of the present invention drives the extrusion frame to move upward continuously through the telescopic part 2, so that the extrusion frame can extrude the rotating plate during the process of bending the inner liner enclosure, so that it can rotate in a state of being inclined outside the forming frame until the rotating end is flush with the side of the forming frame. During the process, the rotating frame will be pulled by the pull plate and the pull rope to rotate, and each rotating frame will be driven to rotate 90°, so that the extrusion oblique block is rotated from a state parallel to the front and rear edges of the inner liner enclosure blank to a vertical state. As the extrusion frame continues to move upward, its upper end will contact the extrusion oblique block and drive the extrusion oblique block to move toward the forming frame, bending the inner liner enclosure again. When the size is appropriate, the inner liner enclosure can be directly processed into a frame shape. At this time, only one welding and one splicing seam are required to complete the processing, which effectively improves the processing quality and is also convenient for installation in medical refrigerators with regular inner walls.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the attached drawings from Figure 1 to Figure 13 It is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention. Embodiment 1

[0039] As Figure 1-7As shown in the figure, the present invention discloses a processing device for the inner liner apron of a medical freezer, including a processing frame 1. A lower top plate 5 is slidably connected to the processing frame 1, and a first telescopic member 6 is connected between the lower top plate 5 and the processing frame 1. Slide frames 7 are slidably connected to the outer sides of the processing frame 1, and a third telescopic member 10 is connected between the slide frames 7 and the processing frame 1. An upper top plate 13 is also slidably connected above the lower top plate 5. Molding frames 18 are slidably connected to both sides of the upper top plate 13 and the lower top plate 5. Guide blocks 19 connected to both ends of each molding frame 18 are slidably connected to the slide frames 7, and as Figure 1 shown, the slide frames 7 are symmetrically and slidably arranged on the left and right sides of the processing frame 1, and the slide frames 7 are concave-shaped and extend from the bottom of the processing frame 1 to the upper part of the processing frame 1 respectively from the front and rear sides;

[0040] Rotating plates 22 are rotatably connected to the molding frames 18 on both sides of the lower top plate 5 through spring hinges. Rotating frames 24 are rotatably connected to the guide blocks 19 through spring hinges. A pressing inclined block 26 is slidably connected to the rotating frame 24. A rotating shaft 28 is connected to the lower end of the rotating frame 24, and a winding drum 29 is connected through the rotating shaft 28. A pulling plate 35 is slidably arranged between the upper and lower molding frames 18 on the same side. A pulling rope 36 is connected between the pulling plate 35 and the winding drum 29, and a push rod 34 in contact with the rotating plate 22 is connected to the pulling plate 35. A stamping assembly is arranged on the slide frame 7, and the stamping assembly is used to cooperate with the molding frame 18 and the pressing inclined block 26 to perform stamping processing on the inner liner apron blank 41. An adjusting assembly for distance adjustment is arranged between the upper top plate 13 and the lower top plate 5.

[0041] Guide rails 2 are connected to both sides of the processing frame 1. The two sides of the lower top plate 5 are respectively slidably connected in the guide rails 2 on both sides. Guide rods 3 are symmetrically connected to both sides of the processing frame 1. The slide frames 7 are slidably sleeved on the outer sides of the guide rods 3. The arrangement of the guide rails 2 can stabilize the lower top plate 5 when it is driven by the first telescopic member 6 to move up and down, and the sliding sleeve of the slide frames 7 on the outer sides of the guide rods 3 can also stabilize their own sliding.

[0042] A plurality of square sliding cylinders 11 are arrayedly connected to the upper end surface of the lower top plate 5. A plurality of square rods 12 are arrayedly connected to the lower end surface of the upper top plate 13. The lower ends of the square rods 12 are limited and slidably sleeved in the square sliding cylinders 11, as Figure 6 shown, the sliding of the square rods 12 in the square sliding cylinders 11 can stabilize the up and down sliding of the upper top plate 13 relative to the lower top plate 5.

[0043] A plurality of collar rings 16 are connected to the mutually adjacent side surfaces of the lower top plate 5 and the upper top plate 13. A first slide rod 17 is slidably sleeved in each collar ring 16. One end of the first slide rod 17 away from the lower top plate 5 or the upper top plate 13 is connected to the molding frame 18, as Figure 6As shown, one end of the sliding rod 17 slides within the collar 16 and is limited by the collar 16, while the other end extends to the outside of the lower top plate 5 or the upper top plate 13 and is connected to the forming frame 18, which helps to support the forming frame 18 and stabilize the sliding of the forming frame 18.

[0044] Limit sleeves 20 are connected to the forming frames 18 on both sides of the lower top plate 5, and limit rods 21 are connected to the forming frames 18 on both sides of the upper top plate 13. The lower end of the limit rod 21 is slidably sleeved within the limit sleeve 20. As Figure 6 shown, the sliding sleeve of the limit rod 21 within the limit sleeve 20 helps the upper and lower two forming frames 18 on the same side to slide stably relative to each other when the distance between the upper top plate 13 and the lower top plate 5 is adjusted, and they will not interfere with each other at the same time.

[0045] Limit blocks 23 are connected to the forming frames 18 on both sides of the lower top plate 5. The rotating plate 22 is inclined and limited by the limit block 23 on its respective side. A sliding rod 25 is connected within the rotating frame 24. The squeezing inclined block 26 is slidably sleeved outside the sliding rod 25. A first spring 27 sleeved outside the sliding rod 25 is connected between the squeezing inclined block 26 and the rotating frame 24. As Figure 6 shown, the limit block 23 can ensure that the rotating plate 22 is limited by it under the action of the spring hinge and is in an inclined state. The setting of the sliding rod 25 facilitates the stable sliding of the squeezing inclined block 26 relative to the rotating frame 24. At the same time, the setting of the first spring 27 makes the squeezing inclined block 26 located at one end of the rotating frame 24 without external force.

[0046] Sliding rods 30 are connected to the mutually approaching sides of the forming frames 18 on both sides of the lower top plate 5 and the upper top plate 13. A slider 31 is slidably sleeved on the outer side of each sliding rod 30. A second spring 32 sleeved on the outer side of the sliding rod 30 is connected between the slider 31 and the sliding rod 30. An expansion link 33 is connected between the vertically adjacent sliders 31. A pull plate 35 is connected to the slider 31 sliding on the forming frames 18 on both sides of the lower top plate 5. As Figure 7 shown, the sliders 31 slidably connected to the upper and lower forming frames 18 through the sliding rods 30 are connected by the expansion link 33, so that when the distance between the upper top plate 13 and the lower top plate 5 is adjusted, the expansion link 33 can expand and contract adaptively. However, when the sliding frame 7 adjusts its position under the action of the third telescopic member 10, the upper and lower sliders 31 can move synchronously. At the same time, when the rotating plate 22 rotates towards the pull plate 35, it will drive the slider 31 to slide on the sliding rod 30 by compressing the second spring 32 through the push rod 34, and then pull the pull plate 35, the pull rope 36 to drive the reel 29, the rotating shaft 28, and the rotating frame 24 to rotate. And when the rotating end of the rotating plate 22 rotates to a state flush with the upper and lower forming frames 18, at this time the rotating frame 24 just rotates 90°, so that the front and rear rotating frames 24 can rotate from a state of being parallel to each other to a collinear state. Embodiment 2

[0047] As shown in Figure 1-13 the figure, the present invention discloses a processing device for the inner liner apron of a medical freezer. Compared with Embodiment 2, this embodiment discloses the structure of the stamping assembly.

[0048] The stamping assembly includes a second telescopic member 8 and an extrusion frame 9. The second telescopic member 8 is installed on the sliding frame 7, and the extrusion frame 9 is connected to the upper end of the second telescopic member 8. An opening 4 for the extrusion frame 9 to penetrate through is provided on the processing frame 1. The extrusion frame 9 is arranged on the mutually remote sides of the two forming frames 18 on both sides and cooperates with the side surfaces of the forming frames 18. The upper end of the extrusion frame 9 is in sliding contact with the inclined surface of the extrusion inclined block 26.

[0049] As shown in Figure 2 the figure, by driving the extrusion frame 9 to move upward through the second telescopic member 8, the extrusion frame 9 will gradually rise above the processing frame 1 through the opening 4 and be located on the mutually remote sides of the left and right forming frames 18, thereby performing a primary extrusion and bending on the inner liner apron blank 41, so that both ends of the inner liner apron blank 41 are bent at a specific angle, and the maximum bending angle is 90°;

[0050] If it is necessary to perform a secondary bending on the inner liner apron blank 41 to facilitate directly enclosing it into a frame, at this time, the two sides of the inner liner apron blank 41 will be bent by 90° through the upward movement of the extrusion frame 9, and the extrusion frame 9 continues to rise. As both ends of the inner liner apron blank 41 are bent and the extrusion frame 9 moves upward, it will drive the rotating plate 22 to rotate, so as to push the push rod 34 to drive the slider 31 to slide away from the forming frame 18 together with the pull plate 35, and pull the rotating frame 24 to rotate exactly 90° through the pull rope 36. At this time, when the extrusion frame 9 continues to move upward, it will contact the extrusion inclined block 26, causing it to approach the forming frame 18 on one side of the upper top plate 13, thereby performing a secondary bending on the inner liner apron blank 41 after the first bending, facilitating directly bending the inner liner apron blank 41 into a frame, and then forming a splicing seam through one-time welding.

[0051] Specifically, in actual production, the distance between the extrusion frame 9 and the forming frame 18 is generally the thickness value of the inner liner apron blank 41, and the distance between the lower end of the extrusion inclined block 26 and the forming frame 18 is generally also the thickness value of the inner liner apron blank 41, and the mutually remote side surfaces of the upper and lower forming frames 18 are respectively flush with the mutually remote side surfaces of the upper top plate 13 and the lower top plate 5. Embodiment 3

[0052] As shown in Figure 5 and 6 the figure, the present invention discloses a processing device for the inner liner apron of a medical freezer. Compared with Embodiment 2, this embodiment discloses the structure of the adjustment assembly.

[0053] The adjusting assembly includes a threaded barrel 14 and a screw rod 15. The threaded barrel 14 is rotatably connected to the upper end of the lower top plate 5, and the screw rod 15 is connected to the lower end of the upper top plate 13. The lower end of the screw rod 15 is threadedly sleeved inside the threaded barrel 14, so that the distance between the lower top plate 5 and the upper top plate 13 can be adjusted by rotating the threaded barrel 14. Embodiment 4

[0054] As Figure 1 As shown, the present invention discloses a processing device for the inner liner enclosure of a medical freezer. Compared with Embodiment 2, this embodiment discloses a structure for positioning the inner liner enclosure to be processed on both sides of the processing frame 1.

[0055] Both sides of the processing frame 1 are connected with side plates 37. A fourth slide bar 38 is slidably sleeved through the side plates 37. A positioning plate 39 is connected to the fourth slide bar 38, and a lead screw 40 threadedly sleeved with the side plates 37 is rotatably connected to the positioning plate 39.

[0056] By rotating the lead screws 40 on both sides to adjust the distance between the two positioning plates 39, it is convenient to straighten the inner liner enclosure front and back. It is also possible to control the operation of the second telescopic member 8 and the third telescopic member 10, so that the extrusion frame 9 can pass through the opening 4 and slightly protrude above the inner liner enclosure blank 41 on the processing frame 1, and then drive the two extrusion frames 9 to approach each other to drive the inner liner enclosure blank 41 to be centered left and right. Then, drive the lower top plate 5 to move downward through the first telescopic member 6 to press and stabilize the inner liner enclosure blank 41. Finally, control the extrusion frame 9 to be adjusted back below the inner liner enclosure blank 41, which is convenient for subsequent bending processing.

[0057] Working principle:

[0058] First, rotate the lead screws 40 on both sides to adjust the two positioning plates 39 to approach each other, so that the distance between them is slightly larger than the width of the inner liner enclosure blank 41. Then, place the inner liner enclosure blank 41 on the processing frame 1, and at the same time, the inner liner enclosure blank 41 can be centered between the front and back positioning plates 39, and both ends of the inner liner enclosure blank 41 are respectively located in the openings 4 on both sides;

[0059] Start the third telescopic member 10 to adjust the two sliding frames 7 on both sides to drive the two extrusion frames 9 to move away from each other to the outside of both ends of the inner liner enclosure blank 41. Then start the second telescopic member 8 to drive the upper end of the extrusion frame 9 to move upward and pass through the opening 4, and be in a state slightly higher than the processing frame 1. At this time, both extrusion frames 9 are on the outside of both ends of the inner liner enclosure blank 41. Then control the two sliding frames 7 to approach each other, and the inner liner enclosure blank 41 can be driven to be centered left and right by the pushing of the inner liner enclosure blank 41 on both sides;

[0060] Control the extrusion frame 9 to move downward to below the inner liner apron blank 41. At this time, synchronously adjust the positions of the left and right sliding frames 7 again. At this time, the distance between the left and right sliding frames 7 is the length dimension that the inner liner apron blank 41 needs to be bent and formed at one time. Then, the second telescopic member 8 can drive the extrusion frame 9 below the inner liner apron blank 41 to move upward again. At this time, the extrusion frame 9 will cooperate with the forming frames 18 on the left and right sides of the lower top plate 5, and perform a one-time upward bending on both ends of the inner liner apron blank 41. At the same time, as the bending progresses, the bent parts at both ends of the inner liner apron blank 41 will also contact the rotating plate 22 under the condition of being resisted by the extrusion frame 9, causing the rotating plates 22 on both sides to rotate;

[0061] As the rotating plates 22 on both sides rotate closer to each other, they will push the push rods 34 on both sides to drive the sliders 31 to approach each other and compress the second spring 32. At this time, the pull plates 35 connected to the sliders 31 on both sides also slide closer to each other, and pull the corresponding winding drums 29 to rotate through the pull ropes 36, thereby exactly driving the winding drums 29 to rotate 90°, so that the rotating frame 24 and the extrusion wedge 26 can follow and rotate 90°, making the extrusion wedge 26 that was originally parallel to the front and rear edges of the inner liner apron blank 41 rotate to a state perpendicular to the front and rear edges of the inner liner apron blank 41. And until the upper end of the extrusion frame 9 just fits the inclined surface of the extrusion wedge 26, the one-time bending is completed; <{

[0062] When secondary bending is required, continue to control the extrusion frame 9 to move upward. At this time, the upward movement of the extrusion frame 9 will not act on the rotating plate 22. Therefore, the extrusion wedge 26 will remain in a state perpendicular to the front and rear edges of the inner liner apron blank 41. However, the upward movement of the extrusion frame 9 will contact the inclined surface of the extrusion wedge 26, causing the extrusion wedges 26 on the left and right sides in this state to approach each other and cooperate with the forming frames 18 on both sides of the upper top plate 13, and perform secondary bending on both ends of the inner liner apron blank 41 after one-time bending, improving the flexibility of the operation, realizing the arbitrary switching between one-time bending and secondary bending, and also avoiding the single limitation of the existing mold that can only perform one-time bending or can only perform two-time bending.

[0063] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above. Some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
