Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of machinery and relates to a cutting machine for cutting round cloth pieces. Background Art
[0002] In industrial production, round cloth pieces are often used, such as round cloth pieces on the outside of the cloth buckle, and round cloth pieces as samples, etc., which requires professional round cloth cutting equipment. At present, the round cloth pieces are generally cut by punching, that is, the cloth is placed on the cutting table, and the round cutting knife cuts the cloth by punching down. For example, the press-type disc cloth cutting machine disclosed in the Chinese patent document [Application No. 201120190923.X] punches the cloth onto the corresponding disc knife, and cuts the round cloth piece on the cloth by pressure. Through the punching method, the part where the cloth contacts the blade will be torn during the cutting process, which will cause the cloth to deform, and the round cloth piece obtained is not round; the punching method in the above patent is realized by manpower, and only one piece of cloth can be cut at a time. If multiple pieces of stacked cloth are cut at a time, the pressure provided by hydraulic pressure can be obtained to obtain sufficient pressure of about 12 tons. The use of hydraulic pressure leads to a high price and high cost of use of the machine. Summary of the invention
[0003] The purpose of the present invention is to solve the above problems in the prior art and to propose a cutting machine for cutting round cloth pieces. The technical problem solved by the present invention is to be able to cut round cloth pieces from stacked cloths.
[0004] The purpose of the present invention can be achieved by the following technical solutions:
[0005] A cutting machine for cutting circular cloth pieces, comprising a frame and a cloth placing table mounted on the frame, characterized in that the cloth placing table can float up and down relative to the frame, a cutting hole is provided on the cloth placing table, a cloth pressing head is provided on the frame directly above the cutting hole, the cloth pressing head can move downward to press and fix the cloth on the cloth placing table and can cause the cloth placing table to move downward, a cylindrical circular cutting knife is provided on the frame directly below the cutting hole, the circular cutting knife is driven by an electric motor to rotate along an axis, the end of the circular cutting knife facing the cutting hole is a circular blade, and when the cloth placing table moves downward, the blade passes through the cutting hole in a rotating state to cut the cloth.
[0006] When in use, place the stacked fabrics on the fabric placing platen, move the fabrics to the cutting hole position, and the cloth pressing head moves downward first to press and compact the stacked fabrics. After completion, the cloth pressing head continues to move downward to push the fabric placing platen downward. At this time, the circular cutter rotates, and the blade contacts the fabric after passing through the cutting hole. The rotating blade cuts a circular edge on the fabric to cut a circular piece of fabric from the fabric. As the cloth pressing head continues to move downward, the circular cutter can completely penetrate the stacked fabrics. Thus, a number of circular cloth pieces are cut, and after completion, the cloth pressing head is reset upward, and the cloth placing table is automatically reset, thus completing the cutting of the circular cloth pieces. Since a rotating cylindrical circular cutting knife is used to cut the circular cloth pieces from the cloth, it is possible to cut thicker stacked cloth, and more circular cloth pieces can be obtained in one cutting, which is more efficient. There is no need to squeeze the cloth during cutting, and there is no tearing when the cloth contacts the blade, which avoids deformation of the cloth, and obtains high-quality circular cloth pieces with circular edges.
[0007] In the above-mentioned cutting machine for cutting circular cloth pieces, a plurality of guide rods are fixed to the lower side of the cloth placing plate, the frame is provided with guide holes corresponding to the guide rods, the guide rods are passed through the corresponding guide holes, and the outer sleeve of the guide rods is provided with a spring, the upper end of the spring abuts against the lower side of the cloth placing plate, and the lower end of the spring abuts against the frame. When the cloth placing plate is not under pressure, the spring keeps the cloth placing plate in a high position, at which time the cloth placing plate is located above the circular cutting knife; when the cloth pressing head presses the cloth downward, the cloth placing plate is subjected to downward pressure, the spring is compressed, and the cloth placing plate moves downward. In this process, the blade of the circular cutting knife passes through the cutting hole to cut the cloth. After the cutting is completed, the cloth pressing head is reset, and the cloth placing plate is also reset under the action of the spring.
[0008] In the above-mentioned cutting machine for cutting round cloth pieces, a guide sleeve is fixed on the frame, the inner hole of the guide sleeve is the above-mentioned guide hole, and the guide rod passes through the guide sleeve. The guide sleeve can increase the axial length of the guide hole, increase the contact surface with the guide rod, make the guide rod move up and down more stable, and thus make the cloth placing plate more stable.
[0009] In the above-mentioned cutting machine for cutting round cloth pieces, the cutting hole is located at the center between a plurality of guide rods. This structure makes the pressure on each guide rod uniform, thus preventing the cloth placing plate from tilting when being pressed.
[0010] In the above-mentioned cutting machine for cutting circular cloth pieces, both ends of the circular cutting knife are connected, the central hole of the circular cutting knife is a feeding hole, and a feeding guide rail is provided on the frame directly below the circular cutting knife. The circular cloth pieces cut from the cloth by the circular cutting knife are directly pressed into the feeding hole, and the circular cloth pieces directly fall through the feeding hole to the feeding guide rail, thereby realizing the centralized collection of the circular cloth pieces.
[0011] In the above-mentioned cutting machine for cutting circular cloth pieces, a rotating ring is concentrically fixed to the lower end of the circular cutter, the center hole of the rotating ring is aligned with the feeding hole of the circular cutter, the lower end of the rotating ring is rotatably connected to the frame, a belt groove is provided on the outer surface of the rotating ring, and the driving motor and the rotating ring are connected by a belt. The driving motor drives the circular cutter by setting the rotating ring, and the automatic feeding of the circular cloth piece is not affected; gears can also be set on the outer side of the rotating ring, and the driving motor and the rotating ring can drive the circular cutter to rotate through gear transmission.
[0012] In the above-mentioned cutting machine for cutting round cloth pieces, a pressing rod is installed on the frame above the cloth placing plate, the pressing rod is vertically arranged, the cloth pressing head is fixed at the lower end of the pressing rod, a driving source capable of driving the pressing rod to move up and down is installed on the frame, the driving source is a cloth pressing motor fixed on the frame, the upper section of the pressing rod is axially provided with a rack, a cloth pressing gear is fixed on the motor shaft of the cloth pressing motor, and the cloth pressing gear is meshed with the rack. Since the cloth pressing head only needs to compact the stacked cloth, it can be realized without providing too much pressure, so it can be realized by using a motor, the structure is simple and easy to maintain, and the production cost and use cost can be greatly reduced compared with the oil pressure method.
[0013] In the above-mentioned cutting machine for cutting circular cloth pieces, a disc-shaped cutting disc is detachably fixed on the cloth placing table, the center hole of the cutting disc is the above-mentioned cutting hole, the cloth pressing head is detachably fixed on the lower end of the pressing rod, and the diameter of the lower end of the cloth pressing head is larger than the diameter of the cutting hole. The cutting disc is fixed on the cloth placing table by bolts, and the cloth pressing head is fixed on the pressing rod by bolts. According to the different circular cloth pieces to be cut, the cutting disc, the cloth pressing head and the circular cutting knife with the cutting hole of the corresponding diameter are replaced, so that different circular cloth pieces can be cut.
[0014] In the above-mentioned cutting machine for cutting circular cloth pieces, the cloth pressing head is made of wood or plastic. The hardness of the cloth pressing head is less than that of the circular cutting knife and has sufficient compressive strength; when cutting, in order to cut the cloth at the top of the stacked cloths, the blade will inevitably contact the cloth pressing head. The wooden cloth pressing head can withstand the pressure during cloth pressing without damaging the blade, and is low in cost and easy to replace.
[0015] In the above-mentioned cutting machine for cutting round cloth pieces, a guardrail is fixed on the frame above the cloth placing table, the guardrail is "U"-shaped, and the cloth pressing head is located inside the guardrail. The guardrail isolates the cloth pressing head to prevent hands from being put under the cloth pressing head during processing, thereby playing a role of safety protection.
[0016] Compared with the prior art, the cutting machine for cutting round cloth pieces has the advantages of being able to cut thicker cloth at one time and obtain high-quality round cloth pieces in a circular shape, and also has the advantages of higher cutting efficiency and lower machine cost.

DETAILED DESCRIPTION
[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0023] Embodiment 1
[0024] like Figures 1 to 4As shown, the cutting machine for cutting round cloth pieces comprises a frame 1 and a cloth placing plate 2 mounted on the frame 1, the cloth placing plate 2 can float up and down relative to the frame 1, and a disc-shaped cutting disc 24 can be detachably fixed on the cloth placing plate 2. Preferably, in this embodiment, the cutting disc 24 is fixed by magnetic attraction, and of course, it can also be fixed by bolts; the center hole of the cutting disc 24 is a cutting hole 25 that passes through the cloth placing plate 2, and a cloth pressing head 3 is provided on the frame 1 just above the cutting hole 25, and the cloth pressing head 3 is made of wood or plastic. The cloth pressing head 3 is preferably made of wood material, such as oak, etc. The cloth pressing head 3 can move downward to press and fix the cloth on the cloth placing plate 2 and can make the cloth placing plate 2 move downward. A cylindrical circular cutter 4 is provided on the frame 1 just below the cutting hole 25. The circular cutter 4 is driven by the electric drive 45 to rotate along the axis. The end of the circular cutter 4 facing the cutting hole 25 is a circular blade 41. When the cloth placing plate 2 moves downward, the blade 41 passes through the cutting hole 25 in a rotating state to cut the cloth. A guardrail 11 is fixed on the frame 1 above the cloth placing plate 2. The guardrail 11 is "U"-shaped, and the cloth pressing head 3 is located on the inner side of the guardrail 11.
[0025] Four guide rods 21 are fixed to the lower side of the cloth placing platen 2, and the cutting hole 25 is located at the center position between the guide rods 21. Guide sleeves 22 corresponding to the guide rods 21 are fixed on the frame 1. The inner holes of the guide sleeves 22 are guide holes. The guide rods 21 pass through the corresponding guide sleeves 22. A spring 23 is provided on the outer sleeve of the guide rod 21. The upper end of the spring 23 abuts on the lower side of the cloth placing platen 2, and the lower end of the spring 23 abuts on the frame 1.
[0026] The two ends of the circular cutter 4 are through, and the center hole of the circular cutter 4 is a feeding hole 42. A feeding guide rail 12 is provided on the frame 1 directly below the circular cutter 4. The circular cloth piece cut from the cloth by the circular cutter 4 is directly pressed into the feeding hole 42, and the circular cloth piece directly falls to the feeding guide rail 12 through the feeding hole 42. A rotating ring 43 is concentrically fixed to the lower end of the circular cutter 4, and the center hole of the rotating ring 43 is aligned with the feeding hole 42 of the circular cutter 4. The lower end of the rotating ring 43 is rotatably connected to the frame 1. A belt groove 44 is provided on the outer surface of the rotating ring 43. The driving motor 45 and the rotating ring 43 are connected by a belt 451. The driving motor 45 drives the circular cutter 4 by setting the rotating ring 43. Specifically, the circular cutter 4 is made of steel pipe, the lower end of which is inserted into the rotating ring 43 and fixed by bolts. The steel pipe has good thermal conductivity and can quickly dissipate the heat generated by cutting, thereby achieving continuous operation without waiting and improving efficiency. The wall thickness of the steel pipe is 2mm to 5mm.
[0027] A vertically arranged pressing rod 31 is installed on the frame 1 above the cloth placing table 2, and a plug-in slot 311 is opened at the lower end of the pressing rod 31, and the upper end of the cloth pressing head 3 extends into the plug-in slot 311, and the lower end of the cloth pressing head 3 is conical, and the diameter of the lower end of the cloth pressing head 3 is larger than the diameter of the cutting hole 25, which can increase the compressive strength of the cloth pressing head 3, and the cloth pressing head 3 and the pressing rod 31 are fixed by bolts; a driving source that can drive the pressing rod 31 to move up and down is installed on the frame 1, and the driving source is a cloth pressing motor 32 fixed on the frame 1, and the upper section of the pressing rod 31 is axially provided with a rack, and a cloth pressing gear 33 is fixed on the motor shaft of the cloth pressing motor 32, and the cloth pressing gear 33 is meshed with the rack.
[0028] When in use, the stacked cloth is placed on the cloth placing table 2. When the cloth placing table 2 is not pressed, the spring 23 keeps the cloth placing table 2 in a high position. At this time, the cloth placing table 2 is located above the circular cutting knife 4; the cloth moves to the cutting hole 25, and the cloth pressing head 3 moves downward first. The cloth pressing head 3 first presses and compacts the stacked cloth. After completion, the cloth pressing head 3 continues to move downward, pushing the cloth placing table 2 to move downward. At this time, the circular cutting knife 4 rotates, and the blade 41 contacts the cloth after passing through the cutting hole 25. The rotating blade 41 cuts a circular edge on the cloth, thereby cutting a circular cloth piece from the cloth. As the cloth pressing head 3 continues to move downward, the circular cutting knife 4 can completely penetrate the stacked cloth, so as to cut off several round cloth pieces. After completion, the cloth pressing head 3 is reset upward, and the cloth placing table 2 is automatically reset by the spring 23, and the cutting of the round cloth piece is completed. Since the rotating cylindrical circular cutting knife 4 is used to cut the round cloth piece from the cloth, it is possible to cut the thicker stacked cloth, and more round cloth pieces can be obtained in one cutting, which is more efficient. There is no need to squeeze the cloth during cutting, which will not cause a large pressure at the contact position between the cloth and the blade 41, and avoid deformation of the cloth, so that the edge of the obtained round cloth piece is round and will not be deformed, thereby ensuring the quality of the round cloth piece.
[0029] According to tests, the cloth pressing head 3 of the cutting machine only needs to provide a pressure of about 2 tons to achieve continuous cutting of laminated cloth with a thickness of 5 cm to 15 cm.
[0030] Embodiment 2
[0031] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: two parallel "X"-shaped telescopic frames are provided between the cloth placing table and the frame, and guide rails are provided on the cloth placing table and the frame. The two ends of the upper and lower ends of the telescopic frame are slidably connected to the guide rails, and a torsion spring is provided in the telescopic frame to keep the telescopic frame always in a closed trend. When the cloth placing table is not under pressure, the telescopic frame is in a closed state, that is, the vertical angle between the two brackets is small. When the cloth placing table is under pressure, the telescopic frame opens, and the two ends of the two brackets move along the guide rails respectively, and the cloth placing table moves downward, and the torsion spring is tensioned. In this process, the blade of the circular cutter passes through the cutting hole to cut the cloth. After cutting, the cloth pressing head is reset, and the telescopic frame is reset under the action of the torsion spring.
[0032] Embodiment 3
[0033] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that the driving source is a cylinder fixed on the frame, the pressure rod is coaxially arranged with the telescopic rod of the cylinder, and the upper end of the pressure rod is fixed to the telescopic rod of the cylinder through a connecting sleeve. Since the cloth pressing head only needs to compact the stacked cloth, it can be achieved without providing too much pressure, so it can be achieved by using a cylinder, which has a simple structure and is easy to maintain, and can greatly reduce the production cost and use cost compared to the oil pressure method.
[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
