Description

Technical Field

[0001] This utility model relates to the cutting process of round carpets, specifically a carpet edge processing device that facilitates cutting. Background Technology

[0002] Carpets are common home decor items, and they come in a wide variety of styles, designs, and functions. For example, small round rugs are mainly used in conjunction with Japanese tatami mats, or in the currently popular living room designs that do not include coffee tables or sofas.

[0003] For these small round carpets, automated equipment is primarily used for production, as illustrated by Chinese patent CN113319905B, published on May 17, 2022, which discloses a cutting device for round carpets made of coarse wool fabrics. However, the overall purchase and maintenance costs of this equipment are relatively high, making it suitable mainly for large-scale, highly automated factories. For small workshops producing carpets, this equipment is clearly unsuitable. Therefore, the processing of small round carpets mainly relies on manual handheld electric shearing tools, as illustrated by Chinese patent CN111705395A, published on September 25, 2020, which discloses a telescopic shearing tool for a smart robot producing tufted carpets. However, this method is only suitable for trimming woven carpets and not for non-woven carpets. This is because non-woven carpets are processed directly from a single piece of raw material, then wound into rolls, and workers cut the rolls according to the pattern. Utility Model Content

[0004] The purpose of this invention is to provide a carpet edge processing device that facilitates cutting, thereby addressing the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carpet edge processing device that facilitates cutting, comprising a working arm that is driven to move in the vertical direction, a rotating guide rail component that is rotatably arranged in the circumferential direction and distributed in the horizontal direction, wherein at least one moving part equipped with a cutting blade is slidably arranged on the rotating guide rail component.

[0006] It also includes a workbench, on both sides of which are slidably provided with pressing parts that move in the vertical direction. The protrusions fixed on the pressing parts cooperate with the inlay grooves opened on the workbench to pull the carpet taut laterally.

[0007] Preferably, a shearing annular groove is provided on the working surface of the worktable, and the straight-line distance between the inner and outer radii of the shearing annular groove is equal to the moving part's active path on the rotating guide rail.

[0008] Preferably, the machine also includes a base, which is divided into a base and a head according to its structure. The worktable is fixed to the side of the base and the head adjacent to each other by bolts, and the working arm is movably assembled to the head.

[0009] Preferably, a telescopic module is fixedly installed on the top of the machine head, and the working arm is fixedly installed on the output end of the telescopic module.

[0010] Preferably, the end of the working arm is equipped with a bullseye swivel.

[0011] Preferably, the rotary guide includes a bearing sleeve, which is mounted on the working arm;

[0012] The upper part of the mounting seat is welded onto the bearing sleeve, and the lower part of the mounting seat is fixedly mounted on one side of the upper part of the mounting seat by bolts;

[0013] The upper and lower parts of the mounting base are fitted with guide rods that are symmetrically distributed about the center of the bearing sleeve.

[0014] Preferably, a locking seat is fixedly installed on the end of the two guide rods on the same side, and the number of the moving parts is two, which are slidably installed on the two guide rods and are located between the locking seat and the bearing sleeve.

[0015] Preferably, the movable part is structurally divided into an upper part and a lower part.

[0016] The cutting blade includes a rectangular handle that extends through a rectangular hole in the lower half and is locked in place by a pin.

[0017] The upper and lower halves are clamped on the guide rod and fixed by threaded connection of the first bolt handle into the centrally located screw holes on the upper and lower halves.

[0018] Preferably, the protrusion is a right-angled trapezoid with an inclined surface, and the inclined surfaces of two protrusions are distributed adjacent to each other.

[0019] Preferably, an electro-hydraulic push rod is fixedly installed inside the base, and the output end of the electro-hydraulic push rod is fixedly connected to the two pressing parts.

[0020] In the above technical solution, the carpet edge processing device provided by this utility model, which facilitates cutting, has the following beneficial effects: the non-woven carpet to be cut is pulled and moved on the worktable, and the sides of the carpet are restricted by the pressing parts on both sides to prevent it from falling off the worktable. After reaching the predetermined cutting position, the pressing parts move down, pressing down so that the sides of the non-woven carpet are embedded in the inlay groove due to the protrusions, thereby pulling the non-woven carpet into a taut state. At the same time, after the working arm moves down to the predetermined height, the cutting blade pierces the non-woven carpet, and then drives the rotating guide to rotate quickly once to complete the cutting of the circular carpet.

[0021] Furthermore, the aforementioned cutting blade is mounted on the moving part, the purpose of which is to allow for free modification of the cutting size of the circular carpet by adjusting the rotating guide. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-6 This utility model provides a carpet edge processing device that facilitates cutting, including the following embodiments:

[0033] Example 1

[0034] Combination Figure 1 and Figure 2 As shown, the cutting and processing device includes a working arm 1, a worktable 5, and a cutting blade 4. Furthermore, the above modules are mounted on a base 100, which has a U-shaped structure and is functionally divided into a base 101 and a head 102. The worktable 5 is bolted to the side of the base 101 adjacent to the head 102, while the working arm 1 is movably mounted on the head 102.

[0035] Furthermore, in the above embodiment, the working arm 1 is driven to move vertically, thereby causing the cutting blade 4 to move down to a predetermined workstation height for cutting and avoiding material feeding operations. The vertical movement of the working arm 1 can be controlled by an electric push rod, a stepper screw slide module, or a motor-driven screw. Preferably, it is controlled by a telescopic module 7, which is an electro-hydraulic push rod, installed on the top of the machine head 102. The output end of the telescopic module 7 is fixedly installed to the working arm 1 using clamps or other fasteners.

[0036] Furthermore, a bullseye wheel 8 is installed at the end of the working arm 1. After the working arm 1 moves down to the predetermined position, the non-woven carpet is fixed to the working table 5.

[0037] Example 2

[0038] Based on the above embodiment 1, this embodiment aims to provide a rotating guide rail 2 that can adapt to carpet cutting with different circumferences, and the rotating guide rail 2 has at least one sliding part 3 equipped with a cutting blade 4.

[0039] Specifically, the rotary guide component 2 includes a bearing sleeve 21, and the inner ring of the bearing inside the bearing sleeve 21 is fixedly mounted on the working arm 1. Further, an upper mounting base 22 is welded onto the bearing sleeve 21, and a lower mounting base 23, secured by bolts, is fixedly mounted on one side of the upper mounting base 22. The adjacent surfaces of the upper mounting base 22 and the lower mounting base 23 have arc-shaped grooves, which, when assembled, form a circular hole for fixing the guide rod 24.

[0040] Furthermore, guide rods 24 symmetrically distributed about the center of the bearing sleeve 21 are assembled on the upper part 22 and the lower part 23 of the mounting base. Locking seats 25 are fixedly installed on the ends of the two guide rods 24 on the same side. Two movable parts 3 are slidably mounted on the two guide rods 24 and move between the locking seats 25 and the bearing sleeve 21. The locking seats 25 consist of an upper and a lower seat, which clamp the two guide rods 24 and then fix them in place by threading a second bolt handle 251 into the internal threaded holes on the upper and lower seats. The rotary guide rail 2 provided in this application is driven by human power. Alternatively, an electric motor and its corresponding gears can be added to replace human power, depending on actual needs.

[0041] Example 3

[0042] Based on the above embodiment two, this embodiment aims to provide a detachable movable part 3 and a detachable structure between the cutting blade 4 and the movable part 3, specifically:

[0043] The movable part 3 is structurally divided into an upper part 31 and a lower part 32, and the cutting blade 4 includes a rectangular handle, which extends into the lower part 32 through a rectangular hole and is locked in place by a pin. The upper part 31 and the lower part 32 are clamped on the guide rod 24 and are fixed by a first bolt handle 33 threaded into a centrally located screw hole on the upper part 31 and the lower part 32.

[0044] The clamping of the guide rod 24 by the upper half 31 and the lower half 32 can be controlled by turning the knob first bolt handle 33, thereby facilitating the movement of the moving part 3 on the guide rod 24. Furthermore, scale lines are provided on the guide rod 24 to facilitate control of the position of the moving part 3.

[0045] Furthermore, a shearing groove 52 is provided on the working surface of the workbench 5. The straight-line distance between the inner and outer radii of the shearing groove 52 is equal to the movement path of the moving part 3 on the rotating guide rail 2. That is to say, when the cutting blade 4 moves down to cut, after it descends to the predetermined position, it will pierce the taut non-woven carpet and then be located inside the shearing groove 52, with the blade maintaining a predetermined distance from the bottom of the shearing groove 52.

[0046] It should be noted that the cutting blade 4 in the above embodiment has two sides, namely the sides in the clockwise and counterclockwise rotation directions, as the cutting edge. This means that the cutting operation can be performed by rotating the guide rail 2 clockwise or counterclockwise according to the worker's operating habits.

[0047] Example 4

[0048] Based on the above embodiment one, this embodiment aims to provide a component for pulling a non-woven carpet taut. On both sides of the worktable 5, there are vertically movable pressing parts 6, and the protrusions 61 fixed on the pressing parts 6 cooperate with the inlay grooves 51 opened on the worktable 5 to pull the carpet taut laterally.

[0049] Combination Figure 3 As shown, the protrusion 61 is a trapezoidal inclined support, and the inclined surfaces of the two protrusions 61 are adjacent to each other.

[0050] The actuator of the pressing part 6 here is an electro-hydraulic push rod fixedly installed inside the base 100, and the output end of the electro-hydraulic push rod is fixedly connected to the two pressing parts 6.

[0051] Specifically, the non-woven carpet to be cut is pulled and moved on the worktable 5, with the sides of the carpet restricted by the pressing parts 6 on both sides to prevent it from falling off the worktable 5. After reaching the predetermined cutting position, the pressing parts 6 move down, pressing down so that the sides of the non-woven carpet are pulled taut because the protrusions 61 are embedded in the inlay grooves 51. At the same time, the working arm 1 moves down to the predetermined height and the cutting blade 4 pierces the non-woven carpet, and then the rotating guide rail 2 is driven to rotate quickly once to complete the cutting of the circular carpet.

[0052] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
