Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, specifically a moisture-proof packaging device for mica processing. Background Technology
[0002] The moisture-proof packaging of processed mica needs to take into account its moisture absorption characteristics (traditional mica boards are prone to bubbling and delamination when exposed to moisture). It is achieved through a three-level protection of "pre-treatment for moisture protection + sealed packaging + environmental control". The specific methods include post-processing pre-treatment (reducing the moisture content of mica) and moisture-proof packaging. Moisture-proof packaging can be divided into inner packaging and outer packaging. When choosing inner packaging, vacuum packaging or using moisture-proof bags + desiccants can be selected for moisture protection. The moisture-proof bags should be made of polyethylene (PE) moisture-proof bags (with added VCI vapor phase rust inhibitor), with silica gel desiccant (dosage at 50-100g per cubic meter of packaging space) or montmorillonite desiccant (moisture absorption rate >30%). Direct contact with mica should be avoided (the desiccant should be wrapped with breathable paper). After the mica is packed in the moisture-proof bags, the bag opening needs to be sealed. A sealing device is required for sealing.
[0003] In existing technologies, when sealing moisture-proof bags, workers place the bag opening directly under the sealer of the heat-sealing equipment. This can result in a tilted sealing line, creating noticeable visual defects. Furthermore, the distance between the sealing position and the bag opening cannot be adjusted. If the fixed distance is too large, it will occupy too much space in the bag, reducing the effective capacity, which is uneconomical, especially for small-sized products or packaging valuable materials. If the distance is too small, the sealing edge may be too narrow, resulting in insufficient sealing strength. Additionally, when the sealer presses down to heat-seal the moisture-proof bag opening, it drops instantly, causing contact with the platform. Over long-term sealing operations, this constant contact and impact can cause significant wear and tear on the sealing equipment, making it prone to damage. Utility Model Content
[0004] The purpose of this invention is to provide a moisture-proof packaging device for mica processing, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof packaging device for mica processing, comprising a packaging frame and a pressing table fixed inside the packaging frame, and further comprising:
[0006] A hot air unit is installed above the pressing table to seal the moisture-proof bag of mica packaging. The bottom of the hot air unit is provided with a cushioning element to improve the sealing effect.
[0007] A baffle plate is installed on the top of the pressing table to control the flatness of the sealing of the moisture-proof bag. The pressing table is equipped with an adjustment component for adjusting the distance of the baffle plate. The adjustment component includes a rotating rod rotatably connected to the inner wall of the pressing table. A turntable and a drive gear are respectively fixed at both ends of the rotating rod. A driven gear is meshed with the outer side of the drive gear. A screw is fixed at the axis of the driven gear. The two ends of the screw are rotatably connected to the packing rack and the inner wall of the pressing table through bearings. A movable plate is threaded to the outer side of the screw. A connecting rod is fixed to the top of the movable plate. The connecting rod is fixed to the bottom of the baffle plate.
[0008] Preferably, the inner wall of the pressing table is provided with a through groove, and the connecting rod is slidably connected to the inner wall of the through groove.
[0009] Preferably, the top of the pressing table is provided with two symmetrical sliding grooves, and the inner wall of the sliding groove is slidably connected to a slider, which is fixed to the bottom of the baffle.
[0010] Preferably, the outer side of the rotating rod is rotatably connected to three support frames, and the three support frames are equally fixed to the inner wall of the pressing table.
[0011] Preferably, the hot air component includes a hydraulic cylinder fixed to the top of the packing frame, and a sealing device is detachably installed at the bottom end of the piston rod of the hydraulic cylinder. Two telescopic rods are mirror-fixed between the sealing device and the packing frame.
[0012] Preferably, the buffer includes a pressure plate disposed below the sealer, and a limit rod is fixedly fixed to the top of the pressure plate at equal intervals. The limit rod is slidably connected to the inner wall of the sealer.
[0013] Preferably, a spring is sleeved on the outer side of the limiting rod, and the spring is fixed between the sealing device and the pressure plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This utility model allows workers to easily control the distance between the sealing position and the opening of the moisture-proof bag by setting an adjustment component. By adjusting the distance, the effective capacity of the packaging bag is reduced due to an excessively large fixed distance, or the sealing strength is insufficient due to an excessively small fixed distance, thus optimizing material utilization. The buffer component set below the sealer can reduce the impact force of the sealer when it is pressed down, improve the buffering effect, and prevent the sealer from being damaged by contact and impact with the pressing table when it is pressed down.

[0022] 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.
[0023] Please see Figure 1-5 As shown, a moisture-proof packaging device for mica processing includes a packaging frame 1 and a pressing table 2 fixed inside the packaging frame 1. It also includes a hot air component 3 disposed above the pressing table 2 for sealing the moisture-proof bag of mica packaging. The bottom of the hot air component 3 is provided with a buffer component 4 for improving the sealing buffering effect. A baffle 5 is disposed on the top of the pressing table 2 for controlling the flatness of the sealing of the moisture-proof bag. An adjustment component 6 for adjusting the distance of the baffle 5 is disposed inside the pressing table 2.
[0024] A certain amount of mica material is placed into a moisture-proof bag, and a small bag of silica gel desiccant is placed inside the bag. Then, the opening of the moisture-proof bag is placed on the pressing table 2, and the outermost edge of the opening of the moisture-proof bag is pressed against the baffle 5. The hot air component 3 is pressed down to seal the opening of the moisture-proof bag. When the bag is pressed down to seal, the impact force of the instantaneous pressing is reduced by the buffer component 4, which improves the cushioning effect and prevents the hot air component 3 from being damaged by contact and collision with the pressing table 2. The distance between the baffle 5 and the buffer component 4 can be adjusted by setting the adjustment component 6, thereby adjusting the sealing distance of the opening of the moisture-proof bag.
[0025] The hot air component 3 includes a hydraulic cylinder 31 fixed to the top of the packing frame 1. A sealing device 32 is detachably installed at the bottom end of the piston rod of the hydraulic cylinder 31. Two telescopic rods 33 are fixed between the sealing device 32 and the packing frame 1 in a mirror image.
[0026] By installing a hydraulic cylinder 31 on the top of the packing rack 1, the sealing device 32 can be moved downwards by the driving force of the hydraulic cylinder 31 to seal the moisture-proof bag containing mica placed on the pressing table 2. The specific working principle of the sealing device 32 has been disclosed in the application "A Sealing Device for a Food Packaging Bag" with application number such as "CN202022653152.5". The heating sealing principle of the sealing device 32 is as described in the comparative case, where the upper heating plate 12 and the lower heating plate 11 work together for heating. During heat sealing, the sealing device 32 uses heating elements (heating wire, heating rod) to fuse the heat-sealing layer of the packaging material, and then compresses it with a pressure device. The specific structure, working principle, and possible control methods and spatial arrangement of the technical feature 32 can be selected using conventional methods in the field and will not be elaborated here. When the sealing device 32 is pressed down to the lowest point, it is the same as the lowest point of the pressure plate 41. By setting two telescopic rods 33 in mirror fixation between the sealing device 32 and the packing frame 1, the movement of the sealing device 32 can be limited by the extension and retraction of the telescopic rods 33 when the sealing device 32 is pressed down, thereby improving the stability of the sealing device 32 when it moves down. The working principle of the telescopic rods 33 is common knowledge known to those skilled in the art and has been disclosed in the prior art, so it will not be elaborated here.
[0027] The buffer 4 includes a pressure plate 41 disposed below the sealer 32. The top of the pressure plate 41 is fixed with limit rods 42 evenly spaced. The limit rods 42 are slidably connected to the inner wall of the sealer 32. A spring 43 is sleeved on the outer side of the limit rods 42. The spring 43 is fixed between the sealer 32 and the pressure plate 41.
[0028] By setting a pressure plate 41 below the sealer 32, the pressure plate 41 can fix the moisture-proof bag when the sealer 32 presses down to seal it, making the bag opening more stable during heat sealing and improving the sealing stability of the mica storage moisture-proof bag. By fixing a limiting rod 42 on the top of the pressure plate 41, the limiting rod 42 can slide inside the sealer 32 when the pressure plate 41 is pressed down. At the same time, the pressure plate 41 will squeeze the spring 43. Through the elasticity of the spring 43, the pressure plate 41 can achieve a certain buffer when it moves down. When the limiting rod 42 slides inside the sealer 32, the movement of the pressure plate 41 can be effectively limited.
[0029] The adjusting assembly 6 includes a rotating rod 61 rotatably connected to the inner wall of the pressing table 2. A turntable 62 and a drive gear 63 are fixed to both ends of the rotating rod 61, respectively. A driven gear 64 is meshed with the outer side of the drive gear 63. A screw 65 is fixed at the axis of the driven gear 64. Both ends of the screw 65 are rotatably connected to the inner walls of the packing rack 1 and the pressing table 2 via bearings. A movable plate 66 is threaded to the outer side of the screw 65. A connecting rod 67 is fixed to the top of the movable plate 66 and to the bottom of the baffle 5. A through groove 68 is provided on the inner wall of the pressing table 2, and the connecting rod 67 is slidably connected to the inner wall of the through groove 68. Two symmetrical sliding grooves 69 are provided on the top of the pressing table 2. A slider 610 is slidably connected to the inner wall of the sliding grooves 69 and is fixed to the bottom of the baffle 5. Three support frames 611 are rotatably connected to the outer side of the rotating rod 61, and the three support frames 611 are equally fixed to the inner wall of the pressing table 2.
[0030] When adjusting the distance between the baffle 5 and the sealing device 32, the operator rotates the turntable 62 to drive the rotating rod 61 to rotate. The turntable 62 is located on the outside of the pressing table 2, and the rotating rod 61 rotates on the inner wall of the pressing table 2. When the rotating rod 61 rotates, it can drive the driving gear 63 to rotate. Since the driving gear 63 and the driven gear 64 are meshed, the rotation of the driving gear 63 can drive the driven gear 64 to rotate. Since the screw 65 is fixed at the axis of the driven gear 64, when the driven gear 64 rotates, it can drive the moving plate 66, which is threaded to its outside, to move axially along the screw 65. Since the connecting rod 67 is fixed to the moving plate 66 and the driven gear 64, the operator can drive the moving plate 66, which is threaded to its outside, to move axially along the screw 65. Between the baffles 5, when the moving plate 66 can drive the connecting rod 67 to move, it can also drive the baffle 5 to move. By opening a through groove 68 on the top of the pressing table 2, the connecting rod 67 can move in the through groove 68, which in turn makes it easier for the baffle 5 to move on the pressing table 2. By opening two symmetrical sliding grooves 69 on the top of the pressing table 2, the slider 610 fixed at the bottom of the baffle 5 can slide on its inner wall, limiting the movement of the baffle 5 and thus improving the stability of the movement of the baffle 5. By setting three equally spaced support frames 611 inside the pressing table 2, the rotating rod 61 can be supported, improving the stability when it rotates and drives the drive gear 63 to rotate.
[0031] Working principle: The operator adjusts the distance between the baffle 5 and the sealer 32 according to the required sealing distance by adjusting component 6, puts a certain amount of mica material into the moisture-proof bag, and puts a small bag of silica gel desiccant into the bag. Then, the mouth of the moisture-proof bag is placed on the pressing table 2, and the outermost edge of the mouth of the moisture-proof bag is pressed against the baffle 5, so that the hot air component 3 presses down to seal the mouth of the moisture-proof bag. When pressing down to seal, the buffer component 4 can reduce the impact force of the instantaneous pressing and improve the cushioning effect.
