Abstract
Description
Technical Field
[0001] This utility model relates to the field of oven rack technology, specifically an SMC sheet oven rack. Background Technology
[0002] SMC (Sheet Molding Compound) material is mainly composed of SMC special yarn, unsaturated resin, low-shrinkage additives, fillers, and various auxiliaries. SMC has superior electrical properties, corrosion resistance, light weight, and ease and flexibility in engineering design. Its mechanical properties are comparable to some metal materials, so it is widely used in transportation vehicles, construction, electronics / electrical industries, etc. When SMC is applied to specific industries and fields, SMC sheets processed by SMC sheet forming machines are widely used. SMC sheets fresh from the SMC sheet forming machine need to be dried before leaving the production line. However, the current drying operation for SMC sheets usually involves placing an oven rack inside the oven and placing the SMC sheets on the rack for drying. Since most oven racks are perforated sheet structures, and the SMC sheets do not move after being placed, the lower surface of the SMC sheets will be dried unevenly, which will reduce the material properties of the SMC sheets. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 The present invention provides an SMC sheet 6 drying oven rack, comprising a base plate 1, a support plate 2, and a plurality of SMC sheets 6, wherein the base plate 1 is located below the support plate 2, and the SMC sheets 6 are placed on the upper end of the support plate 2.
[0025] The bearing plate 2 has a frame 3 around its periphery. The upper end of the base plate 1 is fixedly provided with a support frame 7 and a lifting assembly 16. The top of the support frame 7 is fixedly provided with a positioning shaft 8. Two fixing frames 9 and a first screw 10 are symmetrically provided on both sides of one end of the bearing plate 2. The first screw 10 passes through the fixing frame 9 and is threadedly connected to the fixing frame 9. One end of the first screw 10 is provided with a first limiting seat 11. The inside of the first limiting seat 11 is provided with a limiting groove 12. The two ends of the positioning shaft 8 are respectively inserted into the inside of the two limiting grooves 12.
[0026] Two guide frames 14 are symmetrically arranged on both sides of the other end of the bearing plate 2. The guide frame 14 is provided with a guide groove 15. The output end of the lifting assembly 16 is provided with a crossbar 17. Two guide rods 18 are symmetrically arranged at both ends of the crossbar 17, which pass through the guide groove 15 and slide in cooperation with the guide frame 14.
[0027] The working principle of the SMC sheet 6 drying oven rack is based on the lifting component 16 driving the support plate 2 to rotate around the positioning shaft 8, thereby achieving the effect of reciprocating tilting of the support plate 2, and thus causing the position of the SMC sheet 6 to change in order to achieve the purpose of uniform drying on both sides.
[0028] In this embodiment, the lifting assembly 16 is a telescopic cylinder.
[0029] In this embodiment, one end of the guide rod 18 is provided with a second screw 19 that is inserted into the crossbar 17. The second screw 19 is threadedly connected to the crossbar 17. The threaded connection allows the guide rod 18 to be easily disassembled at both ends of the crossbar 17.
[0030] In this embodiment, the outer end of the first screw 10 is provided with a toggle block, which makes the first screw 10 easy to operate.
[0031] After the lifting assembly 16 (telescopic cylinder) is activated, the crossbar 17 at its output end will move up and down. The guide rods 18 at both ends of the crossbar 17 slide within the guide grooves 15 of the guide frame 14, which restricts the crossbar 17 to move only in the direction specified by the guide grooves 15.
[0032] Since one end of the support plate 2 is connected to the positioning shaft 8 at the top of the support frame 7 via the first limiting seat 11 on the first screw 10, when the crossbar 17 moves up and down, it will cause the support plate 2 to swing around the positioning shaft 8 as the fulcrum. This will change the position of the SMC sheet 6 placed on the support plate 2, avoiding the problem of uneven drying caused by the lower surface of the SMC sheet 6 being in the same position. This allows the hot air to act more evenly on all parts of the SMC sheet 6, improving the drying effect.
[0033] Operating steps:
[0034] 1) Fix the support frame 7 and the lifting assembly 16 (telescopic cylinder) on the base plate 1.
[0035] 2) Fix the positioning shaft 8 to the top of the support frame 7.
[0036] 3) Install the fixing bracket 9 and the first screw 10 on both sides of one end of the bearing plate 2, install the first limiting seat 11 on one end of the first screw 10, and rotate the first screw 10 so that the two ends of the positioning shaft 8 are respectively inserted into the limiting grooves 12 of the two first limiting seats 11.
[0037] 4) Install guide frames 14 on both sides of the other end of the bearing plate 2.
[0038] 5) Connect the guide rod 18 to the crossbar 17 via the second screw 19, so that the guide rod 18 passes through the guide groove 15 of the guide frame 14.
[0039] 6) Place the SMC sheet 6 to be dried neatly on the top of the support plate 2. The frame 3 around the support plate 2 can prevent the SMC sheet 6 from slipping.
[0040] 7) Place the assembled oven rack containing the SMC sheet 6 into the oven.
[0041] 8) Start the lifting assembly 16 (telescopic cylinder) to make it work. The crossbar 17 drives the guide rod 18 to slide in the guide groove 15, thereby causing the bearing plate 2 to swing back and forth around the positioning shaft 8.
[0042] 9) During the drying process, pay close attention to the drying effect and equipment operation, observe the drying status of SMC sheet 6, ensure that it is heated evenly, and check whether the lifting assembly 16 is working properly and whether the guide rod 18 slides smoothly in the guide groove 15.
[0043] 10) Once the SMC sheet 6 has reached the required drying time, turn off the lifting assembly 16 (telescopic cylinder), remove the drying rack from the drying oven, and then remove the dried SMC sheet 6 from the support plate 2.
[0044] In this embodiment, the inner wall of the limiting groove 12 is provided with a plurality of second balls 13 that contact the positioning shaft 8. The plurality of second balls 13 can reduce the friction between the positioning shaft 8 and the first limiting seat 11.
[0045] In this embodiment, the guide rod 18 and the second screw 19 are an integral structure.
[0046] The lifting assembly 16 drives the support plate 2 to swing back and forth, so that the position of the SMC sheet 6 changes continuously, avoiding the lower surface from always being in the same position. This effectively solves the problem of uneven drying of the SMC sheet 6 and improves the material properties of the SMC sheet 6.
[0047] The overall structure consists of simple components such as base plate 1, bearing plate 2, support frame 7, and lifting assembly 16. The assembly and operation process is relatively easy, reducing the labor intensity and technical requirements of operators.
[0048] The guide rod 18 is threadedly connected to the crossbar 17 via the second screw 19, which facilitates disassembly and installation, and makes it convenient to maintain and replace components such as the guide rod 18.
[0049] Multiple second balls 13 arranged on the inner wall of the limiting groove 12 reduce the friction between the positioning shaft 8 and the first limiting seat 11, making the swing of the bearing plate 2 smoother and extending the service life of the equipment.
