Description

Technical Field

[0001] This utility model relates to the field of SMC sheet processing technology, specifically to an SMC sheet roll forming equipment. Background Technology

[0002] SMC is made of unsaturated polyester resin, thickener, glass fiber, filler and other mixtures, and covered with polyethylene film on both sides. It has excellent mechanical properties, corrosion resistance and dimensional stability.

[0003] To overcome the above-mentioned defects, prior art 1 (Chinese patent with announcement number CN216032501U, announcement date 2022-03-15) describes a film pressing device for SMC sheet processing. This utility model relates to the technical field of SMC sheet processing equipment. A lifting cylinder is fixed to the inner bottom surface of a fixed frame, and the pushing end of the lifting cylinder is aligned with the inner bottom surface of the workpiece support. A support frame is fixed to the left inner wall of the fixed frame. Two support shafts are respectively screwed onto the front and rear inner walls of the support frame via bearings. Rolling... The roll is housed within a support frame, with grooves at the bottom of both ends. The upper side of the grooves has an arc-shaped structure, allowing the roll to be secured to the support shaft via these grooves. Two clamping rods are fixed to the inner top surface of their respective grooves and inserted into clamping slots on the support shaft. A film guide is positioned above the workpiece support, with guide grooves on both its left and right side walls. This allows the workpiece to contact the film, driving the rollers to perform a rolling operation on the film, ensuring the film covers the workpiece and preventing wrinkles.

[0004] While existing technology can avoid wrinkling, the thickness of the sheets varies, and the distance between the two sets of rollers is fixed and cannot be adjusted. The fixed distance between the rollers cannot meet the processing requirements of different subsequent sheets, resulting in low device adaptability and significant processing limitations.

[0005] Therefore, we propose an SMC sheet roll forming equipment to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an SMC sheet roll forming equipment to solve the problems mentioned in the background art, which are that the thickness of the sheet varies, but the distance between the two sets of rollers is fixed and cannot be adjusted. The fixed distance of the rollers cannot meet the processing requirements of different subsequent sheets, resulting in low adaptability of the device and large processing limitations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an SMC sheet roll forming equipment, including a worktable, a fixed frame fixedly connected to the upper surface of the worktable, and an export frame fixedly connected to the side of the upper surface of the worktable to assist in exporting the processed SMC sheet. An upper pressure roller and a lower pressure roller are arranged inside the fixed frame, and an adjustment mechanism is provided between the end of the fixed frame and the shaft end of the upper pressure roller. The adjustment mechanism drives the upper pressure roller to adjust its height by extending and retracting the telescopic rod contained therein. A gas collecting pipe is fixedly connected to the lower rear end of the fixed frame, and the gas collecting pipe cleans the lower pressure roller synchronously through the operation of the adjustment mechanism.

[0008] Furthermore, the adjustment mechanism includes a limiting frame, which is fixedly connected to the inner side of the fixed frame. A slider is nested inside the limiting frame, and an adjustment seat is fixedly connected between the two sets of sliders. The shaft end of the upper pressure roller is rotatably connected to the center position of the adjustment seat. The telescopic rod is fixedly connected to the upper end of the fixed frame, and the output end of the telescopic rod is fixedly connected to the upper surface of the adjustment seat.

[0009] Furthermore, the slider forms a sliding structure with the adjusting seat and the limiting frame, and the lower end of the limiting frame is higher than the highest point of the lower pressure roller. In addition, two sets of limiting frames are symmetrically arranged about the center point of the adjusting seat.

[0010] Furthermore, an auxiliary groove is vertically provided at the center of the fixed frame, and the shaft end of the upper pressure roller is nested and slidably connected inside the auxiliary groove and extends outward.

[0011] Furthermore, an airbag is fixedly connected to the rear side of the fixing frame, and a pressure plate is fixedly connected to the upper end of the airbag, and a connecting rod is fixedly connected to the inner side of the pressure plate.

[0012] Furthermore, the fixing frame is provided with a sliding groove, the connecting rod is nested and slidably connected to the inside of the sliding groove, and the other end of the connecting rod is fixedly connected to the outside of the slider.

[0013] Furthermore, a connecting pipe is provided between the lower side of the airbag and the air collection pipe, and a nozzle is provided through the upper surface of the air collection pipe, with the output end of the nozzle facing the lower pressure roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Equipped with an output rack, after the SMC sheet is processed, it will be discharged outward synchronously by the assistance of the upper and lower pressure rollers. At this time, the output rack can assist in limiting the discharged sheet, thereby facilitating the subsequent collection of the sheet.

[0016] 2. The user can start the adjustment mechanism to operate the device. The adjustment mechanism can drive the upper pressure roller to adjust its height, thereby adjusting the distance between the upper and lower pressure rollers. With the assistance of the adjustment mechanism, the adaptability of the device can be improved, so that the device can better roll forming the sheet material of different thicknesses.

[0017] 3. Activate the telescopic rod to adjust the height of the upper pressure roller by driving the adjusting seat. While the adjusting seat moves, it can simultaneously drive the sliders on both sides to slide along the inside of the limiting frame. The limiting frame can limit the sliders, thereby further improving the stability of the adjusting seat movement. This ensures that the adjusting seat always drives the upper pressure roller to move stably, thereby reducing the occurrence of the upper pressure roller deflecting during movement and affecting the subsequent pressing effect.

[0018] 4. During the up-and-down movement of the upper pressure roller, the auxiliary groove can limit the position of the shaft end of the upper pressure roller, thereby preventing the upper pressure roller from moving laterally. Through the cooperation of the auxiliary groove and the limiting frame, the upper pressure roller can be limited in multiple directions.

[0019] 5. When the upper pressure roller is height adjusted, the slider moves and drives the pressure plate to squeeze the air bag through the connecting rod. After the air bag is squeezed, the gas inside can be sprayed out through the nozzle to spray the lower pressure roller, thereby reducing the adhesion of dust on the surface of the lower pressure roller and further preventing the phenomenon of dust adhering to the lower pressure roller and affecting the subsequent pressing effect.

[0027] 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.

[0028] Example 1: As Figure 1 , Figure 2 , Figure 4 and Figure 5 The present invention provides the following technical solution: an SMC sheet roll forming equipment, which discloses an adjustment mechanism. The adjustment mechanism enables the device to better roll form sheets of different thicknesses: a fixed frame 4 is fixedly connected to the upper surface of the worktable 1, and an export frame 5 for assisting in the export of processed SMC sheets is fixedly connected to the side of the upper surface of the worktable 1. An upper pressure roller 2 and a lower pressure roller 3 are arranged inside the fixed frame 4, and an adjustment mechanism is arranged between the end of the fixed frame 4 and the shaft end of the upper pressure roller 2. The adjustment mechanism drives the upper pressure roller 2 to adjust its height by the extension and retraction of the telescopic rod 7 included therein. The adjustment mechanism includes a limit frame 6, which is fixedly connected to the inner side of the fixed frame 4. A slider 14 is nested inside the limit frame 6, and an adjustment seat 9 is fixedly connected between the two sets of sliders 14. The shaft end of the upper pressure roller 2 is rotatably connected to the center position of the adjustment seat 9. The telescopic rod 7 is fixedly connected to the upper end of the fixed frame 4, and the output end of the telescopic rod 7 is fixedly connected to the upper surface of the adjustment seat 9.

[0029] An outlet frame 5 is inclinedly set at the front end of the upper pressure roller 2 and the lower pressure roller 3. After the SMC sheet is processed, it will be discharged outward synchronously with the assistance of the upper pressure roller 2 and the lower pressure roller 3. At this time, the outlet frame 5 can assist in limiting the discharged sheet, so as to facilitate the subsequent collection of the sheet. The user can start the adjustment mechanism to run it and start the telescopic rod 7. At this time, the telescopic rod 7 can drive the adjustment seat 9 to move up and down, thereby further adjusting the height of the upper pressure roller 2, thereby adjusting the distance between the upper pressure roller 2 and the lower pressure roller 3. When the sheet thickness is different, the distance between the upper pressure roller 2 and the lower pressure roller 3 is also different. With the assistance of the adjustment mechanism, the adaptability of the device can be improved, so that the device can better roll forming the sheet of different thicknesses.

[0030] Example 2: Figure 4 and Figure 5 The present invention provides the following technical solution: an SMC sheet roll forming equipment, which discloses a limiting frame 6 and an auxiliary groove 8. The cooperation between the auxiliary groove 8 and the limiting frame 6 further improves the stability of the movement of the upper pressure roller 2. The slider 14 forms a sliding structure with the limiting frame 6 through the adjusting seat 9. The lower end of the limiting frame 6 is higher than the highest point of the lower pressure roller 3. The limiting frame 6 is symmetrically arranged with two sets about the center point of the adjusting seat 9. The auxiliary groove 8 is vertically opened at the center of the fixed frame 4. The shaft end of the upper pressure roller 2 is nested and slidably connected inside the auxiliary groove 8 and extends outward.

[0031] While the adjusting seat 9 moves, it can simultaneously drive the sliders 14 on both sides to slide along the inside of the limiting frame 6. The limiting frame 6 can limit the sliders 14, thereby further improving the stability of the adjusting seat 9's movement. This ensures that the adjusting seat 9 always drives the upper pressure roller 2 to move stably, reducing the occurrence of deflection of the upper pressure roller 2 during movement and affecting the subsequent pressing effect. During the up-and-down movement of the upper pressure roller 2, its two shaft ends can simultaneously slide along the auxiliary grooves 8 opened on the fixed frame 4. At this time, the auxiliary grooves 8 can limit the position of the shaft ends of the upper pressure roller 2, thereby preventing the upper pressure roller 2 from moving laterally. Through the cooperation of the auxiliary grooves 8 and the limiting frame 6, the upper pressure roller 2 can be limited in multiple directions, further improving the stability of the upper pressure roller 2's movement.

[0032] Example 3: Figure 2 , Figure 3 and Figure 6 The present invention provides the following technical solution: an SMC sheet roll forming equipment, which discloses an air bag 10, through which air can be supplied to the air collection pipe 12, thereby realizing the dust removal treatment of the lower pressure roller 3: the lower rear end of the fixed frame 4 is fixedly connected to the air collection pipe 12, and the air collection pipe 12 performs dust removal treatment on the lower pressure roller 3 synchronously through the operation of the adjustment mechanism. The fixed frame 4 is provided with a sliding groove 17, and the connecting rod 15 is nested and slidably connected to the inner side of the sliding groove 17. The other end of the connecting rod 15 is fixedly connected to the outer side of the slider 14. The lower side of the air bag 10 is connected to the air collection pipe 12 through a connecting pipe 11, and the upper surface of the air collection pipe 12 is provided with a nozzle 13, and the output end of the nozzle 13 is set towards the lower pressure roller 3.

[0033] When the upper pressure roller 2 is height adjusted, the slider 14 can simultaneously drive the connecting rod 15 connected to the outside to slide along the slide groove 17. This causes the connecting rod 15 to drive the pressure plate 16 to squeeze the air bag 10. After the air bag 10 is squeezed, the gas inside can be transported to the inside of the air collection pipe 12 through the connecting pipe 11. At the same time, the gas is sprayed out through the nozzle 13 set above the air collection pipe 12 to spray the lower pressure roller 3, thereby reducing the adhesion of dust on the surface of the lower pressure roller 3 and further preventing the phenomenon of dust adhering to the lower pressure roller 3 and affecting the subsequent pressing effect.
