Description

Technical Field

[0001] This utility model relates to the field of linear refrigerator body foaming technology, and in particular to an adjustment structure for a linear refrigerator body foaming clamp. Background Technology

[0002] The technology of plastic foaming has a long history. The earliest example is foam bakelite in the early 1920s, produced using methods similar to those used to manufacture foam rubber. Rigid polyurethane foam and polystyrene foam appeared in the 1930s; polyethylene, polyvinyl chloride, epoxy resin, and phenolic foams emerged in the 1940s; and expandable polystyrene foam and flexible polyurethane foam appeared in the 1950s. Basically, all plastics, including thermoplastics and thermosetting plastics, can be foamed into foam plastics. Industrial preparation methods include: extrusion foaming, injection molding foaming, molding foaming, calendering foaming, powder foaming, and spray foaming, among others.

[0003] However, for the foamed panels for refrigerators, they need to undergo a series of processes such as punching, grooving, and cutting to fit the refrigerator body structure. However, most existing foaming fixtures are one-to-one, while the refrigerator body size varies, which is not conducive to repeated operations. Similarly, the foaming process itself is prone to local deformation, which is not conducive to subsequent finished product processes. Therefore, we propose an adjustment structure for a linear refrigerator body foaming fixture to solve the above problems. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.

[0021] like Figure 1 and Figure 2 As shown, in this embodiment, the adjustment structure of a linear refrigerator body foaming clamp includes: a base 1, on which a horizontal central rail 2 and symmetrically located adjustment rails 3 and limiting rails 4 are fixed. The adjustment rails 3 include two and are symmetrical to the center of the base 1. Multiple sets of clamping platforms 5 are fixed at equal intervals on the central rail 2. Each clamping platform 5 has a recessed groove 6 formed on its top. An adjustment platform 7 is slidably connected to each adjustment rail 3. A pneumatic pressure block 8 is hinged to the top of the adjustment platform 7. The bottom surface of the pneumatic pressure block 8 is higher than the top surface of the clamping platform 5. A limiting platform 9 is slidably connected to the limiting rail 4. A stop block 11 is rotatably connected to the top of the limiting platform 9 through a rotary motor 10. The stop block 11 corresponds to the groove 6. The adjustment rails 3 and the limiting rails 4 are connected to corresponding driving components 12 on the corresponding sides of the base 1 to drive the adjustment platform 7 and the limiting platform 9 to slide upward on their respective corresponding tracks.

[0022] More specifically, in some embodiments, the driving component 12 includes a turntable 13, a lead screw 14, a bearing seat 15, a slider 16, and a synchronizing block 17. Both ends of the lead screw 14 are rotatably connected to the side of the base 1 via the bearing seat 15. The center of the slider 16 is threadedly engaged with the lead screw 14, and its end is fixedly connected to the adjusting platform 7 and the limiting platform 9 via the synchronizing block 17. The clamping platform 5 includes at least five sets, and the slots 6 are through slots, with the slots 6 on the tops of multiple clamping platforms 5 flush and connected. Positioning holes 18 are equidistantly provided on the central rail 2, and the two sides of the clamping platform 5 are bolted to the positioning holes 18.

[0023] like Figure 3 As shown, for the specific structure of the limiting platform 9, the length of the limiting rail 4 is not less than the length of the middle rail 2. A fixing plate 19 is vertically fixed on the limiting platform 9. The rotary motor 10 is horizontally fixed on the fixing plate 19 and its output end passes through the fixing plate 19. One end of the stop block 11 is fixed to the output end of the rotary motor 10, and the other end is in contact with the communicating surface of the groove 6.

[0024] like Figure 4 As shown, regarding the specific layout and structure of the adjustment platform 7, multiple sets of adjustment platforms 7 are provided between the two adjustment rails 3. The bottom of the adjustment platform 7 located between the two adjustment rails 3 is bolted to the top surface of the base 1. Each adjustment platform 7 is also provided with a servo cylinder 20, a hinge platform 21, a hinge block 22, and a crossbar 23 on its top. The servo cylinder 20 is fixed to the top of the adjustment platform 7 and its output end passes through the hinge platform 21. The hinge platform 21 is fixed to the top of the adjustment platform 7 and is hinged to the outer side of the middle section of the crossbar 23 through the hinge block 22. One end of the crossbar 23 is welded to the pneumatic pressure block 8, and the other end is hinged to the output end of the servo cylinder 20.

[0025] As described above, for the positioning and clamping of the foam, this invention first uses multiple clamping platforms 5 evenly arranged on the central rail 2 for clamping and positioning. The resulting groove 6 can fit the cross-sectional dimensions of the molded foam. After being inserted and placed, one end abuts against the other end (i.e., Figure 1 The rightmost clamping platform 5 has a stop at the other end, and the other end is limited by the rotary motor 10 on the limiting platform 9 in conjunction with the stop block 11. Similarly, in order to avoid deformation and breakage caused by the long length of the foam itself when opening a hole, this utility model also has multiple adjusting platforms 7 staggered on the base 1. Through the output of the servo cylinder 20 on the adjusting platform 7, after one end of the crossbar 23 is lifted, due to the hinge action of its own middle section hinge block 22, it can press down the pneumatic pressure block 8 at the other end, and cooperate with the groove 6 to achieve local pressing of the top surface of the foam board.

[0026] In order to cope with refrigerator foam boards of various structural sizes, in addition to the fixed adjustment platform 7 located in the middle of the base 1, this utility model also uses a drive component 12 to position and slide the adjustment platform 7 on the adjustment rail 3. That is, the turntable 13 rotates and cooperates with the lead screw 14 to be positioned and rotated in the bearing seat 15. The slider 16, which is threaded with the lead screw 14, can slide and be positioned axially by the lead screw 14 under the sliding limit action of the adjustment rail 3, so as to meet the pressing and clamping requirements of different parts of the foam board. The overall adjustment structure is novel, practical and reliable, which greatly improves the efficiency of refrigerator foam boards in processes such as hole cutting, avoids local stress deformation of the foam board, and improves the finished product's processability.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
