Description

Technical Field

[0001] This utility model relates to the technical field of cutting mechanisms, and in particular to the technical field of an eccentric wheel type fabric cutting mechanism. Background Technology

[0002] Fabrics are commonly used materials in decoration, including various types such as chemical fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tape, and flannel. Fabrics play a significant role in decoration and display, often being an indispensable main force in the entire sales space. Using a large amount of fabric for wall decoration, partitions, and background treatment can also create a good commercial space display style.

[0003] Currently, fabrics often need to be cut to the required size. However, the current fabric cutting process results in a lot of waste, and the cut fabric is not precise enough to meet people's needs, increasing the waste rate, affecting the quality of the fabric, and causing economic losses.

[0004] To address the problems mentioned in the background art, for example, application number CN201621008285.4 discloses a precision fabric cutting device, including a machine body, a motor, a first pulley, a belt, a second pulley, a bearing seat, a roller, a main shaft, a cutter disc, a moving blade, a small bevel gear, a large bevel gear, a connecting rod, a transmission shaft, a base, and a reversing cylindrical gear. The motor is located on one side of the machine body, and the first pulley is located at the bottom of the machine body near the motor. Through the rotation of the main shaft, the fabric is evenly transferred to the moving blade, resulting in a uniform and neat arrangement of the cut fabric, saving a lot of manpower for cutting and avoiding fabric waste caused by the inaccuracy of human cutting, thus increasing product quality and utilization rate. However, this device still has the following drawbacks:

[0005] Although the device can cut the fabric neatly, the blade does not have markings, resulting in inaccurate fabric dimensions and affecting the processing quality.

[0006] To address the problems mentioned above, for example, application number CN202022225209.1 discloses a fabric cutting device, including a table. The table includes a first surface and a second surface arranged opposite to each other. The first surface is the working surface, and a sliding plate is slidably connected to the second surface. A blade is rotatably connected to the side of the sliding plate facing the table. The table is provided with a blade groove, which is located on the movement path of the blade's cutting edge. The side of the blade is provided with a scale, and the starting line of the scale is on the side of the blade away from the rotation center. By pulling the blade apart, the blade is separated from the blade groove. The fabric is laid flat on the first surface, and the sliding plate is slid so that the scale corresponding to the cutting length is aligned with the edge of the fabric. The blade is rotated so that it moves into the blade groove, and the blade cuts the fabric, improving the accuracy of fabric cutting. However, this device still has the following drawbacks:

[0007] The aforementioned device cuts the fabric directly by rotating the blade. However, during the cutting process, the blade is prone to getting tangled with the yarn on the fabric, which can easily lead to equipment damage and reduce processing efficiency. Summary of the Invention

[0008] The purpose of this invention is to solve the problems in the prior art by proposing an eccentric wheel-type fabric cutting mechanism, which can drive the cutting blade to move up and down through the rotation of the eccentric wheel, thereby avoiding the situation of yarn tangling.

[0009] To achieve the above objectives, this utility model proposes an eccentric wheel type fabric cutting mechanism, including a fixed base, an eccentric wheel, a connecting shaft, a rotating shaft, a rotating sleeve, a rotating block, a rotating shaft, a mounting block, and a cutting blade. An eccentric wheel is rotatably disposed below the front surface of the fixed base. The connecting shaft is rotatably sleeved on the outer wall of the eccentric wheel. A rotating shaft is rotatably disposed above the front surface of the fixed base. A rotating sleeve is rotatably sleeved on the outer wall of the front end of the rotating shaft. A rotating block is integrally formed on the side wall of the rotating sleeve. The end of the connecting shaft is connected to the rotating block. The rear end of the rotating shaft penetrates the rear surface of the fixed base. A rotating shaft is rotatably sleeved on the outer wall of the rear end of the rotating shaft. A mounting block is disposed above the rear surface of the fixed base. The end of the rotating shaft is connected to the lower part of the mounting block. A cutting blade is disposed above the mounting block.

[0010] Preferably, a mounting hole is provided on the lower rear surface of the fixing base. The mounting hole is used to assemble an external drive motor, which drives the eccentric wheel to rotate.

[0011] Preferably, the rotating block has an elliptical opening, and the end of the connecting shaft is hinged to the opening on the rotating block via a hinge shaft.

[0012] Preferably, the mounting block is hinged to the rear surface of the fixed base via a hinge shaft.

[0013] Preferably, the cutting blade has an L-shaped structure, and the cutting blade moves back and forth up and down by rotating the mounting block.

[0014] Preferably, a protective seat is provided above the rear surface of the fixing seat.

[0015] The beneficial effects of this utility model are:

[0016] This invention utilizes an eccentric wheel, connecting shaft, rotating shaft, rotating sleeve, rotating block, rotating shaft, mounting block, and cutting blade in a coordinated manner to drive the cutting blade to move up and down for cutting. A drive motor is mounted on a mounting hole, and its output shaft is mounted on the eccentric wheel. The drive motor then drives the output shaft to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel drives the connecting shaft to rotate, which in turn drives the rotating block to rotate. The rotating block drives the rotating sleeve to rotate synchronously, which in turn drives the rotating shaft to rotate. The rotating shaft, in turn, drives the mounting block to rotate on the fixed base, thereby causing the cutting blade to move up and down, thus achieving the cutting of fabric edges and corners. Because this application uses the rotation of the eccentric wheel to drive the cutting blade's up and down movement, it avoids the cutting blade from tangling with yarn during rotation, preventing equipment damage and improving cutting efficiency. This solves the problem of the blade easily tangling with yarn on the fabric during rotational cutting, which can easily lead to equipment damage. Attached Figure Description

[0023] See Figures 1 to 5 This utility model discloses an eccentric wheel type fabric cutting mechanism, comprising a fixed base 1, an eccentric wheel 2, a connecting shaft 3, a rotating shaft 4, a rotating sleeve 5, a rotating block 51, a rotating shaft 6, a mounting block 7, and a cutting blade 8. The eccentric wheel 2 is rotatably mounted below the front surface of the fixed base 1, and the connecting shaft 3 is rotatably sleeved on the outer wall of the eccentric wheel 2. The rotating shaft 4 is rotatably mounted above the front surface of the fixed base 1, and the rotating sleeve 5 is rotatably sleeved on the outer wall of the front end of the rotating shaft 4. The rotating block 51 is integrally formed on the side wall of the rotating sleeve 5. The end of the connecting shaft 3 is connected to the rotating block 51, and the rear end of the rotating shaft 4 penetrates the rear surface of the fixed base 1. The outer wall of the rear end of the rotating shaft 4 is rotatably fitted with a rotating shaft 6. A mounting block 7 is provided above the rear surface of the fixed base 1. The end of the rotating shaft 6 is connected to the lower part of the mounting block 7. A cutting blade 8 is provided above the mounting block 7. The connecting shaft 3 is driven to rotate by the eccentric wheel 2. During the rotation of the connecting shaft 3, the rotating block 51 is driven to rotate. The rotating block 51 drives the rotating sleeve 5 to rotate synchronously, thereby driving the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the rotating shaft 6 is driven to rotate. The rotating shaft 6 drives the mounting block 7 to rotate on the fixed base 1, thereby driving the cutting blade 8 to move up and down, thereby realizing the cutting of the edges and corners of the fabric.

[0024] See Figure 2 and Figure 3 The mounting hole 9 is provided on the lower rear surface of the fixed base 1. The mounting hole 9 is used to assemble an external drive motor, which drives the eccentric wheel 2 to rotate. It should be noted that the drive motor is not shown in the figure of this application.

[0025] See Figure 4 The rotating block 51 has an elliptical opening 511. The end of the connecting shaft 3 is hinged to the opening 511 on the rotating block 51 via a hinge shaft. When the rotating block 51 rotates, the end of the connecting shaft 3 can move within the opening 511.

[0026] See Figure 3 The mounting block 7 is hinged to the rear surface of the fixed base 1 via a hinge shaft. When the rotating shaft 6 rotates, it drives the mounting block 7 to rotate on the fixed base 1.

[0027] See Figure 3 The cutting blade 8 has an L-shaped structure. The rotation of the mounting block 7 drives the cutting blade 8 to move up and down reciprocally. When the cutting blade 8 moves upward, the cutting surface of the cutting blade 8 is higher than the height of the fixed base 1. Therefore, when the cutting blade 8 moves downward, it can cut the edges and corners of the fabric.

[0028] See Figure 1 and Figure 2A protective seat 10 is provided above the rear surface of the fixed seat 1, which serves as a protective measure to prevent impurities from splashing upwards.

[0029] The working process of this utility model:

[0030] In the operation of this eccentric wheel-type fabric cutting mechanism, the drive motor is first installed on the mounting hole 9, and the output shaft of the drive motor is installed on the eccentric wheel 2. Then, the drive motor drives the output shaft to rotate, which in turn drives the eccentric wheel 2 to rotate. The eccentric wheel 2 drives the connecting shaft 3 to rotate, and the connecting shaft 3 drives the rotating block 51 to rotate. The rotating block 51 drives the rotating sleeve 5 to rotate synchronously, which in turn drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the mounting block 7 to rotate on the fixed seat 1, thereby driving the cutting blade 8 to move up and down. Then, the operator puts the edge of the fabric under the cutting blade 8, thereby achieving the cutting of the edge of the fabric. Since this application uses the rotation of the eccentric wheel 2 to drive the cutting blade 8 to move up and down, it can avoid the phenomenon of the cutting blade 8 getting tangled with the yarn during rotation, prevent the equipment from being damaged, and thus improve the cutting efficiency.

[0031] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0032] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
