Description

Technical Field

[0001] This utility model relates to a feeding structure for a CNC profiling machine. Background Technology

[0002] Some irregularly shaped boards (such as cutting boards and washboards) are processed using CNC profiling machines. However, traditional CNC profiling machines typically require manual handling. Several stacked boards are placed in the feeding channel, and after each board is fed to the profiling cutter and processed, the operator manually reloads the board. This method has limitations because the feeding channel can only hold a limited number of boards at a time, requiring frequent reloading operations. Manual reloading is time-consuming, impacting overall production efficiency. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by providing a feeding structure for a CNC copying machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a CNC copying machine feeding structure, including a machine base, a feeding channel with an open top on the machine base, a feeding lifting platform for placing multiple vertically stacked plates on the left side of the machine base, the feeding lifting platform lifting several plates upwards to above the feeding channel each time, and a pulling mechanism above the feeding lifting platform for pushing several plates lifted upwards to above the feeding channel from left to right into the feeding channel.

[0005] Furthermore, the material pulling mechanism includes a vertically arranged material pulling push plate, which is located above the machine platform and is used for contact between the left ends of several plates. The material pulling push plate is driven to move left and right by the feeding moving component.

[0006] Furthermore, the feeding moving assembly includes a feeding moving seat disposed above the front side of the feeding channel. The feeding moving seat is driven by a horizontally arranged feeding cylinder to move left and right along a pair of horizontally arranged feeding guide rods. The pulling push plate is connected to the feeding moving seat and moves left and right synchronously with the feeding moving seat.

[0007] Furthermore, the material pulling push plate is located on the left side of the feeding moving seat, and the distance between the material pulling push plate and the feeding moving seat is greater than the length of the material.

[0008] Furthermore, a pair of longitudinal connecting rods distributed on the left and right are fixed at the rear end of the feeding moving seat, and a pair of transverse connecting rods distributed at intervals in front and behind are fixed at the upper end of the pulling push plate. The pair of transverse connecting rods are located above the pair of longitudinal connecting rods. A connecting block is provided at the intersection of each transverse connecting rod and the pair of longitudinal connecting rods. The upper end of the connecting block is slidably engaged with the transverse connecting rod, and the lower end is slidably engaged with the longitudinal connecting rod. Sliding locking handles are also provided at the upper and lower ends of the connecting block.

[0009] Furthermore, the loading lifting platform is driven to move up and down by a loading lifting drive component.

[0010] Furthermore, a first sensor for detecting the board material is provided in the feeding channel. The first sensor is electrically connected to the feeding lifting drive through the control unit. When the first sensor detects that there is no board material in the feeding channel, the control unit receives the signal from the first sensor and controls the feeding lifting drive to work, and the feeding lifting drive drives the feeding lifting platform to move upward.

[0011] Furthermore, a second sensor for detecting the board material is installed above the loading lifting platform. The second sensor and the pulling mechanism are both electrically connected to the control unit. When the second sensor detects the board material, the control unit receives the signal from the second sensor and controls the loading lifting drive to stop, and the control unit controls the pulling mechanism to work.

[0012] Furthermore, the loading lifting platform is mounted on an L-shaped loading lifting frame, and the loading lifting platform slides vertically along the vertical edge of the loading lifting frame. The loading lifting drive component is mounted on the loading lifting frame.

[0013] Furthermore, a horizontally arranged feeding slide is fixed to the top of the vertical side of the feeding lifting frame, and the right end of the feeding slide is connected to the top opening of the feeding channel.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention is reasonably designed and realizes semi-automatic feeding into the feeding channel without the need for frequent manual operation, reducing feeding time and thus improving overall production efficiency.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1-6As shown, this utility model discloses a CNC copying machine feeding structure 100, including a machine base 101. The machine base 101 has a vertically arranged feeding channel 102 with open top and bottom. A feeding lifting platform 103 is arranged on the left side of the machine base 101. The feeding lifting platform 103 is used to place multiple vertically stacked boards. The feeding lifting platform 103 lifts several boards upwards to above the feeding channel 102 each time. A pulling mechanism 104 is arranged above the feeding lifting platform 103. The pulling mechanism 104 is used to push the boards lifted by the feeding lifting platform 103 to above the feeding channel 102 from left to right into the feeding channel 102, thus achieving feeding. In use, multiple boards are manually stacked vertically and placed on the feeding lifting platform. The feeding lifting platform lifts several boards upwards to above the feeding channel each time, and then the pulling mechanism pushes the boards from left to right into the feeding channel. The material is lifted by a loading platform and then transported to the loading channel by a pulling mechanism, realizing semi-automatic loading into the loading channel without frequent manual operation, reducing loading time and improving overall production efficiency.

[0020] In this embodiment, the material pulling mechanism 104 includes a material pulling push plate 105 vertically arranged above the loading lifting platform 103. The material pulling push plate 105 is located above the machine base 101 and is used to contact the left end face of several plates that are lifted upward by the loading lifting platform 103 to the loading channel 102 each time. The material pulling push plate 105 is driven to move left and right by the loading moving component 106 to realize the conveying of several vertically stacked plates from left to right.

[0021] In this embodiment, the feeding moving assembly 106 includes a feeding moving seat 107 vertically arranged above the front side of the feeding channel 102. The feeding moving seat 107 is driven by a horizontally arranged feeding cylinder 108 to move left and right along a pair of horizontally arranged feeding guide rods 109. The pulling push plate 105 is connected to the feeding moving seat 107 and moves left and right synchronously with the feeding moving seat. Specifically, a pair of left and right longitudinal connecting rods 110 are fixed to the rear end of the feeding moving seat 107. A pair of front and rear spaced transverse connecting rods 111 are fixed to the upper end of the pulling push plate 105. The pair of transverse connecting rods 111 are located above the pair of longitudinal connecting rods 110. A connecting block 112 is provided at the intersection of each transverse connecting rod 111 and the pair of longitudinal connecting rods 110. The upper end of the connecting block 112 is slidably engaged with the transverse connecting rod 111, and the lower end is slidably engaged with the longitudinal connecting rod 110. By having the connecting blocks slide and engage with the horizontal and vertical connecting rods respectively, the position of the material pulling plate can be easily adjusted in the front-back and left-right directions, thereby adapting to different sizes of boards and improving the flexibility of use.

[0022] In this embodiment, to facilitate sliding locking, sliding locking handles 113 are respectively provided at the upper and lower ends of the connecting block 112. The upper sliding locking handle 113 is used to lock the left and right movement of the transverse connecting rod 111, and the lower sliding locking handle 113 is used to lock the forward and backward movement. It should be noted that the sliding locking handle is an existing mature product. It is threaded to the connecting block and is set on the opening of the through hole side of the connecting block to facilitate the sliding passage of the connecting rod. By rotating the sliding locking handle, the opening of the through hole side is reduced, thereby achieving locking. The use of sliding locking handles makes operation simple and convenient, without the need for tools, improving the convenience of manual operation.

[0023] In this embodiment, the material pulling push plate 105 is located on the left side of the feeding moving seat 107, and the distance between the material pulling push plate 105 and the feeding moving seat 107 is greater than the length of the material.

[0024] In this embodiment, the loading lifting platform 103 is driven to move up and down by the loading lifting drive component 114. Further, the loading lifting platform 103 is mounted on an L-shaped loading lifting frame 115, with the loading lifting platform 102 and the vertical edge of the loading lifting frame 115 sliding vertically together. The loading lifting drive component is mounted on the loading lifting frame. Specifically, the loading lifting drive component 114 includes a loading lifting motor and a sprocket drive component mounted on the loading lifting frame. The chain of the sprocket drive component is connected to the loading lifting platform, and the loading lifting motor is connected to the sprocket of the sprocket drive component. The loading lifting motor drives the loading lifting platform to move up and down through the sprocket drive component.

[0025] In this embodiment, a first sensor 117 for detecting the board material is provided in the feeding channel 102. The first sensor is electrically connected to the feeding lifting motor of the feeding lifting drive through a control unit (such as a PLC). When the first sensor detects that there is no board material in the feeding channel, the control unit receives the signal from the first sensor and controls the feeding lifting drive to work. The feeding lifting drive drives the feeding lifting platform to move upward, thereby lifting several boards upward to the top of the feeding channel.

[0026] In this embodiment, a second sensor 118 for detecting the board material is provided above the loading lifting platform 103. The second sensor 118 and the loading cylinder of the pulling mechanism are electrically connected to the control unit. When the second sensor detects the board material, the control unit receives the signal from the second sensor and controls the loading lifting motor of the loading lifting drive to stop. The control unit controls the loading cylinder of the pulling mechanism to work. The loading cylinder drives the loading moving seat and the pulling push plate to move synchronously from left to right to realize the pushing of the material.

[0027] In this embodiment, both the first sensor and the second sensor can be photoelectric sensors.

[0028] In this embodiment, a horizontally arranged loading slide plate 116 is fixed to the top of the vertical side of the loading lifting frame 115. The right end of the loading slide plate 116 is connected to the top opening of the loading channel 102. The loading slide plate is used to support the plate when it moves from left to right.

[0029] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0030] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0031] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.
