Description

Technical Field

[0001] The utility model relates to the technical field of composite material processing equipment, in particular to a quick-disassembly glue scraping device for wet-method glue dipping equipment which is convenient for cleaning and parallelism adjustment. Background Art

[0002] Composite materials are a new type of material composed of reinforcing materials and resins. One processing method for composite materials is the wet process. This process involves impregnating the reinforcing material into a low-viscosity resin solution, allowing the low-viscosity resin solution to penetrate into the reinforcing material on its own, and then passing the impregnated reinforcing material through a rubber squeeze roller with a set gap value, squeezing out the excess resin in the reinforcing material through the gap limit.

[0003] In this way, when the rubber roller surface is out of contact with the reinforcement material, part of the resin and the fiber hairiness remaining on the surface of the reinforcement material will adhere to the rubber roller surface. At this time, when the rubber roller surface repeatedly contacts the reinforcement material below, the resin and fiber hairiness remaining on the roller surface will cause uncontrollable contamination to the reinforcement material (may be transferred or may not be transferred). The above defects will cause uncontrollable risks to the production of composite materials.

[0004] Therefore, the utility model provides a quick-release glue scraping device for wet glue dipping equipment, which is convenient for cleaning and parallelism adjustment, so as to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-Figure 4 As shown, this embodiment provides a quick-detachable glue scraping device for wet dipping equipment which is easy to clean and adjust the parallelism, including a frame 1, a glue squeezing roller 3 is rotatably connected to the frame 1, a rotating cylinder 4 is symmetrically fixed to the frame 1, a glue scraping seat 6 is fixedly installed between the two rotating cylinders 4, a glue scraping plate 9 is detachably connected to the bottom surface of the glue scraping seat 6, a scraper 7 is installed between the glue scraping plate 9 and the glue scraping seat 6, the outer blade surface of the scraper 7 is in contact with the glue squeezing roller 3, and an adjusting eccentric shaft 11 is symmetrically rotatably connected to the glue scraping seat 6, and the adjusting eccentric shaft 11 is in contact with the inner blade surface of the scraper 7.

[0023] When in use, the scraper seat 6 is driven to rotate by the rotating cylinder 4, and the scraper seat 6 drives the scraper 7 and the scraper pressing plate 9 to move. When the scraper 7 contacts the rubber extrusion roller 3, the rotating cylinder 4 stops, and the scraper 7 can remove the residue on the rubber extrusion roller 3 to reduce pollution; the scraper 7 can be fine-tuned by adjusting the eccentric shaft 11, and the outer blade surface of the scraper 7 is completely in contact with the roller surface of the rubber extrusion roller 3 to ensure the cleaning effect. The utility model can scrape off the residual resin and fiber hairiness on the roller surface of the rubber extrusion roller 3, and can discharge them along the two ends of the roller surface, and has a parallelism adjustment function, which can make it completely in contact with the roller surface. At the same time, the whole is easy to install and disassemble, which is conducive to self-cleaning.

[0024] Further optimizing the scheme, the bottom surface of the scraper 7 is attached with a PTFE pressing block 8, and the PTFE pressing block 8 is located between the scraper 7 and the scraper pressing plate 9. The function of the PTFE pressing block 8 is to use its elasticity to completely fit the scraper 7 and the scraper seat 6, eliminating the gap between them to prevent resin from penetrating.

[0025] Further optimization scheme, positioning holes are symmetrically opened on the scraper seat 6 and the scraper pressure plate 9, and the adjustment eccentric shaft 11 extends into the positioning hole and is rotatably connected with the positioning hole. The setting of the positioning hole is convenient for adjusting the fixation of the eccentric shaft 11 and the adjustment work; when the eccentric shaft 11 is rotated and adjusted, the vertical distance between the blade surface of the scraper 7 and the positioning hole can be adjusted by eccentricity, that is, the inclination angle between the scraper 7 and the circumferential axis of the scraper seat 6 is adjusted.

[0026] In a further optimized solution, the scraper plate 9 and the scraper seat 6 are detachably connected by fixing screws 10. The detachable manner facilitates the cleaning of each part, and the setting of the fixing screws 10 allows the scraper plate 9 and the scraper seat 6 to press and lock the scraper 7 and the PTFE pressing block 8.

[0027] Further optimizing the scheme, the outer side of the fixing screw 10 and the outer side of the adjusting eccentric shaft 11 are respectively sleeved with a screw sheath 12. The screw sheath 12 can protect the fixing screw 10 and the adjusting eccentric shaft 11 to prevent splashing resin.

[0028] Further optimizing the scheme, a quick-release fixing seat 5 is installed on the flange surface of the output end of the rotary cylinder 4, and the quick-release fixing seat 5 is detachably connected to the end of the scraper seat 6. The setting of the quick-release fixing seat 5 facilitates the installation and removal of the scraper seat 6.

[0029] Further optimization scheme, a U-shaped positioning groove is provided on the quick release fixing seat 5, and round shafts are provided at both ends of the scraper seat 6, and the round shafts are adapted to the U-shaped positioning groove. A fixed thread is provided at the bottom of the U-shaped positioning groove, and the scraper seat 6 adopts a plate-type structure with round shafts at both ends (the two ends are concentric), and cylindrical head countersunk holes are provided radially at both ends of the round shafts. The round shafts at both ends of the scraper seat 6 are installed in the U-shaped positioning groove of the quick release fixing seat 5. Under the fixing of bolts, the cylindrical head countersunk holes on the scraper seat 6 are fixed to the fixed threads on the quick release fixing seat 5, and the scraper seat 6 is fixed to the quick release fixing seats 5 at both ends.

[0030] According to a further optimized solution, both ends of the rubber squeezing roller 3 are fixed on the frame 1 through bearings 2.

[0031] When installing and debugging this application:

[0032] Install the scraper 7 and the PTFE pressing block 8 between the scraper seat 6 and the scraper pressure plate 9, and slightly lock them with the fixing screws 10, press the rotating cylinder 4, use a feeler gauge or visually check the gap between the scraper 7 and the glue squeezing roller 3. If the gap on one side is larger, adjust the eccentric shaft 11 at this end face, push out the scraper 7, adjust the angle of the scraper 7 until the blade surfaces of the scraper 7 at both ends are completely in contact with the glue squeezing roller 3, fix and lock the fixing screws 10 to completely fix the scraper 7 and the scraper seat 6.

[0033] Working status of this application:

[0034] The cylinder 4 is pressed and rotated, and the scraper 7 contacts the rubber squeezing roller 3 to form a V-shaped area. When the rubber squeezing roller 3 rotates, the residual resin and fiber hairiness on the roller surface are peeled off by the scraper 7 and stored in the V-shaped area. The resin and fiber hairiness in the V-shaped area flow to the two ends of the roller surface under the flow of fluid until they are discharged from the two ends of the roller surface.

[0035] Cleaning status of this application:

[0036] Daily cleaning: Separate the rotary cylinder 4, and the scraper 7 rotates downward. The resin and fiber hairiness on the surface of the scraper 7 drip under the action of gravity. The resin on the upper surface of the scraper 7 and the upper surface of the scraper seat 6 is manually wiped off with a cleaning agent to complete the daily cleaning;

[0037] Since the upper surfaces of the scraper seat 6 and the scraper 7 have no protrusions and are smooth, they are easy to clean. The protrusions such as the fixing screw 10 and the eccentric adjustment shaft are all on the back of the working area (V-shaped area) and do not contact the resin during normal operation and do not need to be cleaned.

[0038] Weekly cleaning:

[0039] Remove the bolts on the quick-release fixing seat 5, and the rubber scraper seat 6 and the scraper 7 assembly can be disassembled. Take out the entire assembly and put it in a cleaning agent for complete cleaning.
