Description

Technical Field

[0001] This utility model belongs to the field of cutting machines, and relates to a cutting machine structure, particularly a V-shaped dual-channel cutting machine. Background Technology

[0002] In existing technologies, to meet the need for cutting long strips of material, manufacturers have designed systems that use conveyor belts to transport the long strips of material and utilize rotary cutters to cut them into segments. When cutting long strips of material with a wider width, the cutting channel of the cutter can only be configured as a single channel due to the limited effective cutting range of the cutter, thus limiting production capacity.

[0003] See Figure 1-Figure 1C The diagram shows a top view, a front view, a feeding mechanism, and a discharging mechanism of a type of cutting machine in the prior art. This type of cutting machine includes a feeding mechanism 1, a cutting host 2, and a discharging mechanism 3. This type of cutting machine uses double-sided conveyor belts to feed raw material M1 and applies intermittent motion of a set length. The cutting trajectory of the cutter C then cuts the raw material M1 into fixed-length segments. The feeding mechanism 1 includes an feeding conveyor belt B1, and the discharging mechanism 3 includes an discharging conveyor belt B3. Figure 2 show Figure 1 A schematic diagram of the configuration between the cutting host 2 and related components in a V-shaped dual-channel cutting machine of the prior art.

[0004] When the raw material is loose, an infeed-side clamping belt B21 and an outlet-side clamping belt B22 are respectively installed on the infeed side and the outlet side of the cutting host 2. The infeed-side clamping belt B21 corresponds to the infeed conveyor belt B1, and the outlet-side clamping belt B22 corresponds to the outlet conveyor belt B3. There is a gap G at the junction of the infeed-side clamping belt B21 and the outlet-side clamping belt B22, which allows the cutting trajectory of the cutter C to pass through during the cutting operation to cut the raw material M1.

[0005] When the width of raw material M1 is large, it will be positioned horizontally. The feed side conveyor belt B21 and the discharge side conveyor belt B22 will then horizontally clamp and feed the raw material M1 for the cutter C to cut into segments. Immediately after the cutter C rotates back to the point where it will pass the previously cut section of raw material M1 again, it will quickly clamp and feed the raw material M1 for a certain length before coming to a stop. This cycle of cutting and feeding is repeated periodically until the entire length of raw material M1 is cut, at which point another new raw material M1 is introduced.

[0006] When the cutter C is performing a cutting operation, its blade rotates along the blade path U (e.g., ...). Figure 2(As shown). The central shaft of the cutter C is attached to a rotating component A, and the rotation center O of the rotating component A is positioned on the fixed base S. The rotating component A can rotate around the rotation center O, thereby driving the blade of the cutter C to travel along the blade path U.

[0007] A motor E drives a cutter C to rotate via a belt L and related pulleys. Initially, the blade trajectory U of the cutter C reaches the bottom of the cross-section of the original material M1, thus completely cutting the workpiece M1. As the cutter C wears down, the connecting rod B can be operated to rotate the fixed base S around the rotation center D, thereby lowering the fixed base S and causing the rotation center O of the rotating component A to descend. This lowers the cutter C towards the original material M1, ensuring that the blade trajectory U of the cutter C reliably passes through the entire cross-section of the original material M1, thus cutting it off.

[0008] To meet the cutting requirements of loosely layered, long strip-shaped raw materials, the feeding mechanism 1 is equipped with a wide-plate feeding conveyor belt B1 with two side guide plates H1 to transport the long strip-shaped raw material M1 into the cutting host 2. The feeding side clamping belt B21 of the cutting host 2 then gradually clamps and feeds the long strip-shaped raw material M1, moving intermittently in sync with the discharge side clamping belt B22. During the time interval when the cutter C is out of the cutting range, the material is fed to a fixed size. When stationary and not feeding, the cutter C cuts the long strip-shaped raw material M1 into segments. After the periodic cutting and feeding action, the finished product M2, after being cut into segments, is discharged by the discharge mechanism 3. The discharge mechanism 3 is also equipped with two side guide plates H2 to support the finished product M2 and prevent it from scattering.

[0009] See Figure 3 As shown, if the long strip of raw material to be cut is a relatively wide product, and a multi-stage cutting structure is adopted to increase production capacity (e.g., including two feed side conveyors B21a and B21b respectively conveying two long strips of raw material M1a and M1b), the blade trajectory U of the cutter C is no longer sufficient for cutting. The blade trajectory U must be expanded to another blade trajectory U1 to cover the entire working range. However, this will cause the rotation center O of the rotating part A to deviate far from the original rotation center, making the component configuration of the entire cutting host 2 extremely difficult. To overcome this problem, the existing technology adopts a pendulum-type motion mode for the cutter's movement, but this requires a larger configuration space, and the pendulum or linear reciprocating transverse cutting motion will make the entire mechanism more complex, increasing the configuration cost and requiring a larger space. Utility Model Content

[0010] The main objective of this invention is to provide a V-shaped dual-channel cutting machine that can efficiently cut wide and long strip materials with low equipment cost and compact equipment configuration space.

[0011] To achieve the aforementioned objectives, this utility model includes a first infeed side conveyor belt for feeding a long strip of raw material from the feeding mechanism into the cutting host; a second infeed side conveyor belt for feeding another long strip of raw material from the feeding mechanism into the cutting host; a first discharge side conveyor belt corresponding to the first infeed side conveyor belt with a gap; a second discharge side conveyor belt corresponding to the second discharge side conveyor belt with a gap; and a cutting blade whose blade path passes through the gap during rotation. The first and second infeed side conveyor belts are arranged in the cutting host with a V-shaped inclination angle. Correspondingly, the first and second discharge side conveyor belts are also arranged in the cutting host with a V-shaped inclination angle. The blade path of the cutting blade covers the entire cross-section of both the long strip of raw material and the other long strip of raw material, thereby cutting the long strip of raw material and the other long strip of raw material to produce multiple finished products.

[0012] The central shaft of the cutter is attached to a rotating component, and the rotation center of the rotating component is positioned on a fixed base. The rotating component can rotate around the rotation center, thereby driving the blade of the cutter to travel along the blade path.

[0013] The first feed side clamping belt and the second feed side clamping belt are arranged in the cutting host with the rotation center of the rotating component as the center and the corresponding V-shaped inclination angle; the first discharge side clamping belt and the second discharge side clamping belt are also arranged in the cutting host with the rotation center of the rotating component as the center and the corresponding V-shaped inclination angle.

[0014] The feeding mechanism includes a first feeding conveyor belt, corresponding to the first feeding side clamping belt; and a second feeding conveyor belt, corresponding to the second feeding side clamping belt.

[0015] The first and second feed conveyors are arranged in the feeding mechanism with corresponding V-shaped inclination angles.

[0016] The discharge mechanism includes a first discharge conveyor belt, corresponding to the first discharge side clamping belt; and a second discharge conveyor belt, corresponding to the second discharge side clamping belt.

[0017] When the first discharge conveyor belt receives and delivers multiple finished products by the first discharge side clamping belt, the angles of its different conveying positions are gradually decreasing inclination angles, wherein the inclination angle has a horizontal working surface, so that the first discharge conveyor belt and the second discharge conveyor belt finally deliver multiple finished products respectively with the horizontal working surface.

[0018] In terms of effectiveness, this invention, without requiring a significant increase in equipment and space, utilizes a dual-channel conveyor belt with a V-shaped configuration to hold long strips of raw material within the original equipment's cutter rotation range, allowing the cutter to perform cutting. Furthermore, the angle of the discharge conveyor belt gradually decreases at different transport positions, ensuring that multiple finished products are delivered from the horizontal working surface, facilitating subsequent processing. This invention offers advantages such as no need for additional control mechanisms, high-speed transport, and low cost.

[0073] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0074] See Figure 4-Figure 4C As shown, the diagrams respectively display a top view, a front view, a feeding mechanism diagram, and a discharging mechanism diagram of the V-shaped dual-channel cutting machine of this utility model. Figure 5 show Figure 4 A schematic diagram showing the configuration of the cutting host 2a and related components. The cutting machine of this utility model includes two feeding mechanisms (first feeding mechanism 1a and second feeding mechanism 1b). The first feeding mechanism 1a includes a first feeding conveyor belt B1a and matching side guide plates H1a. The second feeding mechanism 1b includes a second feeding conveyor belt B1b and matching side guide plates H1b.

[0075] This utility model cutting machine includes two discharge mechanisms (first discharge mechanism 3a and second discharge mechanism 3b). The first discharge mechanism 3a includes a first discharge conveyor belt B3a and matching side guide plates H3a. The second discharge mechanism 3b includes a second discharge conveyor belt B3b and matching side guide plates H3b.

[0076] The cutting host 2a includes two feed side clamping belts (first feed side clamping belt B21a and second feed side clamping belt B21b). The first feed side clamping belt B21a corresponds to the first feed conveyor belt B1a and is equipped with guide plates H21a on both sides. The second feed side clamping belt B21b corresponds to the second feed conveyor belt B1b and is equipped with guide plates H21b on both sides.

[0077] The cutting host 2a includes two discharge-side clamping belts (a first discharge-side clamping belt B22a and a second discharge-side clamping belt B22b). The first discharge-side clamping belt B22a corresponds to the first discharge conveyor belt B3a and is equipped with guide plates H22a on both sides. The second discharge-side clamping belt B22b corresponds to the second discharge conveyor belt B3b and is equipped with guide plates H22b on both sides.

[0078] The first feed conveyor belt B1a, together with the side guide plates H1a, transports the long strip of raw material M1a into the first feed side clamping belt B21a in the cutting host 2a. After the long strip of raw material M1a is cut into segments by the cutter C of the cutting host 2a, multiple finished products M2a are produced and sequentially pass through the first discharge side clamping belt B22a and the first discharge conveyor belt B3a, and are then discharged by the first discharge mechanism 3a.

[0079] The second feed conveyor belt B1b, together with the side guide plates H1b, transports another long strip of raw material M1b into the second feed side clamping belt B21b of the cutting host 2a. After the other long strip of raw material M1b is cut into segments by the cutter C of the cutting host 2a, multiple finished products M2b are produced and sequentially pass through the second discharge side clamping belt B22b and the second discharge conveyor belt B3b, and are then discharged by the second discharge mechanism 3b.

[0080] Figure 5 show Figure 4 A schematic diagram showing the configuration of the cutting host 2a and related components in the dual-channel cutting machine with a V-shaped configuration according to the present invention.

[0081] When the cutter C is performing a cutting operation, its blade edge rotates along the blade edge trajectory U. The central shaft of the cutter C is attached to a rotating component A, and the rotation center O of the rotating component A is positioned on the fixed base S. The rotating component A can rotate around the rotation center O, thereby driving the blade edge of the cutter C to travel along the blade edge trajectory U.

[0082] Motor E drives the cutter C to rotate via belt L and related pulleys. When necessary, the operator can operate linkage B to rotate the fixed seat S around the rotation center D, thereby lowering the fixed seat S and causing the rotation center O of the rotating component A to descend. This causes the cutter C to descend towards the long strip material M1a and the other long strip material M1b, ensuring that the blade trajectory U of the cutter C reliably passes through the entire cross-section of the long strip material M1a and the other long strip material M1b, thus cutting them off.

[0083] In this invention, the first feed-side clamping belt B21a and the second feed-side clamping belt B21b are arranged in the cutting host 2a with a V-shaped inclination angle θ, centered on the rotation center O of the rotating component A. That is, when the cutter C cuts the long strip of raw material M1a and another long strip of raw material M1b, the long strip of raw material M1a and the other long strip of raw material M1b have corresponding inclined working surfaces located on the first feed-side clamping belt B21a and the second feed-side clamping belt B21b, respectively.

[0084] Correspondingly, the first discharge-side clamping belt B22a and the second discharge-side clamping belt B22b are also arranged in the cutting host 2a with a V-shaped inclination angle θ, centered on the rotation center O of the rotating component A. In this way, the output capacity of the equipment can be increased without changing the configuration of the cutting blade and related mechanisms as in the prior art.

[0085] The first feed side clamping belt B21a and the second feed side clamping belt B21b are configured corresponding to the V-shaped inclination angle θ. Therefore, the first feed conveyor belt B1a and the second feed conveyor belt B1b are also configured with a V-shaped inclination angle (e.g., Figure 4B (As shown).

[0086] Regarding the discharge mechanism 3 (first discharge mechanism 3a, second discharge mechanism 3b), after the long strip raw material M1a and another long strip raw material M1b are cut into sections, they are supplied for subsequent processes (such as packaging), exhibiting the characteristics of batch feeding and continuous intermittent discharge. Therefore, in response to the aforementioned first discharge side clamping belt B22a and second discharge side clamping belt B22b set at a V-shaped inclination angle, this utility model specifically designs a first discharge conveyor belt B3a and a second discharge conveyor belt B3b with a gradually tilting structure.

[0087] See Figure 6As shown, in the configuration of the first discharge conveyor belt B3a and the second discharge conveyor belt B3b, this utility model designs a rotating conveyor belt structure to rotate the inclined working surface of the conveyor belt to a horizontal working surface. Taking the first discharge conveyor belt B3a transporting multiple finished products as an example, when the first discharge conveyor belt B3a receives and delivers the finished product M2a from the first discharge side clamping belt B22a, the angles of the first discharge conveyor belt B3a at different transport positions P1~P5 are gradually decreasing asymptotic inclination angles θ1~θ5, where the asymptotic inclination angle θ5 has a horizontal working surface. In this way, the first discharge conveyor belt B3a and the second discharge conveyor belt B3b can deliver each finished product M2a separately on a horizontal working surface, which facilitates subsequent processing operations and has the advantages of no need for additional control mechanisms, high-speed transport, and low cost.

[0088] The above embodiments are merely illustrative of the structural design of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify and vary the above embodiments based on the structural design and concept of this utility model, but such modifications shall still fall within the concept of this utility model and the patent scope defined below. Therefore, the scope of protection of this utility model should be as set forth in the patent claims of this application.
