Description

Technical Field

[0001] This invention relates to the field of edge trimming machine technology, specifically to an automatically adjusting gypsum board edge trimmer. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, and easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties. It is one of the new lightweight building materials currently under development. When using gypsum board to decorate corners or other angled areas, the conventional method is to install it with the bottom board overlapping the top board. However, this method creates seams, which are not aesthetically pleasing. Therefore, to avoid seams, a folding process is generally used. Folding involves using an edge trimming machine to cut a micro-groove on the surface of the gypsum board, and then folding the board. Existing edge trimming machines often use a parallel guide ruler when grooving to ensure the machine moves in a straight line. However, adjusting the length of the parallel guide ruler is inconvenient. First, the bolts on the parallel guide ruler need to be loosened, then the ruler needs to be carefully adjusted to the appropriate length, and finally the bolts need to be tightened again to complete the adjustment.

[0003] As per existing technology, patent publication number CN104703765A discloses an electric trimming machine body comprising a base and a base that can freely slide axially. The base has an axially extending and open slit, and a locking / unlocking mechanism configured to span both ends of the slit. By operating the locking / unlocking mechanism, the electric trimming machine reduces the distance between the two ends of the slit, thereby enabling the base to be securely fastened to the trimming machine body. The locking / unlocking mechanism is a toggle mechanism constructed by a combination of three fulcrums and two connecting rods, and has a shape along the outer circumference of the base. Therefore, this electric trimming machine possesses high operability, robust impact resistance, and excellent maintainability. The trimming machine in the aforementioned patent has the following shortcomings:

[0004] Although the trimming machine in the aforementioned patent has high operability, robust impact resistance, and excellent maintainability, it still requires careful attention when adjusting the length of the parallel guide ruler during use. If the guide ruler has markings, the markings need to be carefully observed to adjust the length of the guide ruler more accurately. If the guide ruler does not have markings, a measuring tape is needed to complete the adjustment. Therefore, the adjustment process is cumbersome and complicated, making the trimming machine inconvenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatically adjusting gypsum board edge trimmer to solve the problems mentioned in the background art, making the trimming machine more convenient to use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatically adjusting gypsum board edge trimmer, comprising an edge trimmer body, an output end connected to a cutter head at the bottom of the edge trimmer body, a base connected to the outer wall at the lower end of the edge trimmer body, a first positioning block connected to the bottom of the base, a connecting plate connected to one end of the base, a second positioning block connected to the bottom of the connecting plate, sliding plates slidably connected to both sides of the base, the two sliding plates being symmetrically arranged, a limit component connected to the end of the sliding plate near the second positioning block, and symmetrically arranged lifting components connected to both sides of the connecting plate, the lifting components matching the limit components.

[0007] Furthermore, both sides of the base are provided with sliding grooves, and a slider is slidably connected inside the sliding groove. The side of the sliding plate closest to the base is connected to the slider.

[0008] Furthermore, the limiting component includes a limiting block and a limiting plate. A through-hole limiting groove is provided at one end of the slide plate near the second positioning block. A matching limiting block is slidably connected inside the limiting groove. The two sides of the upper end of the outer wall of the limiting block are symmetrically connected to the limiting plates.

[0009] Furthermore, a storage groove is provided on the side of the limiting groove away from the second positioning block, and an elastic element is connected to the bottom of the inner side of the storage groove, with the top of the elastic element connected to the bottom of the limiting plate.

[0010] Furthermore, the lifting assembly includes a connecting rod and a lifting plate. The connecting rod is connected to one side of the connecting plate, and the lifting plate is connected to the side of the connecting rod near the slide plate. A lifting groove is provided in the middle of the limiting block, and the lifting groove matches the lifting plate.

[0011] Furthermore, a positioning plate is connected to the end of the base away from the connecting plate.

[0012] Furthermore, the cross-section of the groove is trapezoidal.

[0013] Furthermore, the lower end of the limiting block has a rounded corner on the side away from the connecting plate.

[0014] Furthermore, the height of the lifting plate is not less than the distance from the bottom of the limiting block to the bottom of the sliding plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This type of automatically adjusting gypsum board edge trimmer, when used to groove gypsum board for edge trimming, first determines the location to be grooved on the gypsum board. Then, the cutter head at the lower end of the edge trimmer body is aligned with this location and pressed against the side wall of the gypsum board. Simultaneously, the edge trimmer body and cutter head are restricted by the limiting component, ensuring that the end of the base is parallel to the side wall of the gypsum board. Then, the edge trimmer body is pushed to move. Under the restriction of the limiting component, the edge trimmer body moves in a direction perpendicular to the side wall of the gypsum board, thus ensuring that the micro-groove is vertical. During the movement of the edge trimmer, the first positioning block and the second positioning block enter the micro-groove in sequence, thereby continuously positioning and restricting the cutter head. The lifting component lifts the limiting component to prevent it from detaching from the base and facilitates the movement of the edge trimmer. This edge trimmer body does not require repeated adjustment of the parallel guide ruler, making it more convenient to use. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Please see Figure 1-7 An automatically adjusting gypsum board edge trimmer includes a trimmer body 1, a cutter head 2 connected to the output end of the trimmer body 1, a base 3 connected to the outer wall of the lower end of the trimmer body 1, a first positioning block 11 connected to the bottom of the base 3, a connecting plate 10 connected to one end of the base 3, a second positioning block 12 connected to the bottom of the connecting plate 10, sliding plates 6 slidably connected to both sides of the base 3, the two sliding plates 6 being symmetrically arranged, a limit component connected to the end of the sliding plate 6 near the second positioning block 12, and symmetrically arranged lifting components connected to both sides of the connecting plate 10, the lifting components matching the limit components.

[0027] The automatically adjusting gypsum board edge folding device of this invention, when the edge trimming machine body 1 is needed to groove the gypsum board for edge folding, first determines the position on the gypsum board where the groove needs to be made, then aligns the cutter head 2 at the lower end of the edge trimming machine body 1 with that position, and presses the base 3 onto the top of the gypsum board. Simultaneously, the limiting component slides to the end of the base 3 near the gypsum board, making the end of the base 3 parallel to the side wall of the gypsum board. This limiting component restricts the edge trimming machine body 1 and the cutter head 2. Then, when the worker pushes the edge trimming machine body 1, under the restriction of the limiting component, the edge trimming machine body 1 will move in a direction perpendicular to the side wall of the gypsum board, thus ensuring that the micro-groove is vertical. During the movement of the edge trimming machine body 1, the first positioning block 11 and the second positioning block 12 will sequentially enter the micro-groove... In the groove, the cutter head 2, the first positioning block 11, and the second positioning block 12 form a straight line, and the side walls of the first positioning block 11 and the second positioning block 12 abut against the inner wall of the micro groove cut into the plasterboard, thereby providing a continuous positioning effect for the cutter head 2, allowing the cutter head 2 to always maintain a straight line movement. After one end of the second positioning block 12 enters the micro groove, the lifting component will contact the limiting component, thereby lifting the limiting component. This not only prevents the limiting component from detaching from the base 3, but also facilitates the movement of the trimming machine body 1. When using the trimming machine body 1 to cut micro grooves in the plasterboard, it is not necessary to repeatedly adjust the parallel guide ruler. Therefore, the trimming machine body 1 is more convenient to use. In addition, the internal structure of the trimming machine body 1 in this invention is similar to the internal structure of the electric trimming machine disclosed in the prior art, so it will not be described in detail here.

[0028] As a preferred technical solution of the present invention, the base 3 has a sliding groove 4 on both sides, and a slider 5 is slidably connected inside the sliding groove 4. The side of the sliding plate 6 closest to the base 3 is connected to the slider 5.

[0029] Specifically, the slide plate 6 slides against the base 3 via the slider 5, allowing the slide plate 6 to slide to any position on either side of the base 3. When positioning the body 1 of the trimming machine before it is opened to create a micro-groove, the slide plate 6 can be slid to the end of the base 3 away from the connecting plate 10, thus facilitating the positioning of the base 3 and the entire trimming machine body 1 by the limiting component. After positioning, when the trimming machine body 1 is pushed to move, the base 3 will move together with the trimming machine body 1, while the slide plate 6 and the limiting component will temporarily remain in their original positions to ensure that the cutter head 2 can move in a straight line until the lifting component lifts the limiting component. At this point, the slide plate 6 will move together with the base 3 to prevent the slide plate 6 from being lost.

[0030] As a preferred technical solution of the present invention, the limiting component includes a limiting block 7 and a limiting plate 8. The end of the slide plate 6 near the second positioning block 12 is provided with a through limiting groove 601. The limiting groove 601 is slidably connected to the limiting block 7. The upper sides of the outer wall of the limiting block 7 are connected with symmetrically arranged limiting plates 8.

[0031] Specifically, before using the trimming machine body 1 to cut the micro-groove, the slide plate 6 can be slid to a suitable position, and the limiting block 7 can be slid down until the limiting plate 8 contacts the top of the slide plate 6. At this time, the limiting block 7 and the slide plate 6 form a right angle. By abutting the limiting block 7 against the side wall of the plasterboard, the end of the base 3 can be made parallel to the side wall of the plasterboard. This ensures that when the trimming machine body 1 is pushed to move, the V-shaped micro-groove cut by the cutter head 2 will be parallel to the edge line of the plasterboard end, and the cutter head 2 can maintain a straight line when moving.

[0032] As a preferred technical solution of the present invention, a storage groove 602 is provided on the side of the limiting groove 601 away from the second positioning block 12, and an elastic member 9 is connected to the bottom of the inner side of the storage groove 602, and the top of the elastic member 9 is connected to the bottom of the limiting plate 8.

[0033] Specifically, when the limiting block 7 is not subjected to external force, the elastic element 9 will pull the limiting plate 8 downward, so that the bottom of the limiting block 7 extends from the bottom of the sliding plate 6 to form an L-shape, making it easier and more convenient for workers to position the device before slotting.

[0034] As a preferred technical solution of the present invention, the lifting assembly includes a connecting rod 13 and a lifting plate 14. The connecting rod 13 is connected to one side of the connecting plate 10, and the lifting plate 14 is connected to the side of the connecting rod 13 near the slide plate 6. A lifting groove 701 is provided in the middle of the limiting block 7, and the lifting groove 701 matches the lifting plate 14.

[0035] Specifically, when using the trimmer body 1 to perform grooving, after the cutter head 2 has cut out the micro-groove, the first positioning block 11 will enter the micro-groove. After the first positioning block 11 enters, the second positioning block 12 will also enter the micro-groove. After the second positioning block 12 has entered the micro-groove a certain distance, the lifting plate 14 will be inserted into the lifting groove 701. Since the side of the lifting plate 14 is set as a right triangle and the cross section of the lifting groove 701 is set as a right trapezoid, after the lifting plate 14 is inserted into the lifting groove 701, the limiting block 7 will be pushed upward by the lifting plate 14, so that the limiting block 7 will retract into the limiting groove 601, thereby allowing the slide plate 6 to move together with the base 3, preventing the slide plate 6 from detaching from the base 3, thus increasing the probability of the slide plate 6 being lost.

[0036] As a preferred embodiment of the present invention, a positioning plate 15 is connected to the end of the base 3 away from the connecting plate 10.

[0037] Specifically, the positioning plate 15 restricts the slide plate 6 to prevent it from detaching from the base 3. The distance from the side of the limiting block 7 away from the lifting plate 14 to the end of the slide plate 6 away from the limiting block 7 is equal to the distance from the cutter head 2 to the positioning plate 15. Therefore, when the slide plate 6 abuts against the positioning plate 15, if the limiting block 7 abuts against the side wall of the gypsum board, the cutter head 2 will also abut against the side wall of the gypsum board. Thus, when using the limiting component to limit the position before grooving, it is only necessary to push the limiting block 7 towards the gypsum board to complete the fixing and restriction of the trimming machine body 1, making it easier for workers to perform grooving work on the gypsum board.

[0038] As a preferred embodiment of the present invention, the slide groove 4 has a trapezoidal cross-section. The trapezoidal slide groove 4 has a better restraining effect, which facilitates the sliding of the slider 5 in the slide groove 4 and prevents the slide plate 6 from detaching from the base 3.

[0039] As a preferred embodiment of the present invention, the lower end of the limiting block 7 is provided with a rounded corner on the side away from the connecting plate 10. The rounded corner makes the lower end of the limiting block 7 closer to the gypsum board smoother, so that the limiting block 7 will not scratch the thick paper on the surface of the gypsum board when it moves with the base 3.

[0040] As a preferred embodiment of the present invention, the height of the lifting plate 14 is not less than the distance from the bottom of the limiting block 7 to the bottom of the sliding plate 6. If the height of the lifting plate 14 is less than the distance from the bottom of the limiting block 7 to the bottom of the sliding plate 6, when the lifting plate 14 lifts the limiting block 7 upward, the side wall of the limiting block 7 will easily abut against the connecting rod 13, which will cause the limiting block 7 to be unable to fully retract into the limiting groove 601, making it impossible for the trimming machine body 1 to perform the grooving work normally.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
