[0035] Please refer to Figures 1 to 4 . The embodiment of the present application provides a cutting mechanism, including: a fixing plate 1, a slider 2, a connecting block 3, a driving member 4, a cutting knife 5 and a bearing portion 6.

[0036] Wherein, a slide rail 101 extending in the vertical direction is fixedly provided on the inner side surface of the fixing plate 1. The fixing plate 1 is provided with a first opening 102. The slider 2 is slidably connected to the slide rail 101. The connecting block 3 is fixedly connected to the surface of the slider 2 facing away from the slide rail 101. The driving member 4 is connected to the connecting block 3 and is used to drive the connecting block 3 to move in the vertical direction. The cutting knife 5 is fixedly connected to the lower end of the connecting block 3 and is used to cut the workpiece. The bearing portion 6 is located below the cutting knife 5 and is used to bear the workpiece. Part of the bearing portion 6 passes through the first opening 102.

[0037] The cutting mechanism provided by this embodiment realizes automatic cutting with high safety and precision without manual operation by setting a fixing plate 1, a slider 2, a connecting block 3, a driving member 4, a cutting knife 5, and a bearing portion 6. After the workpiece is placed on the bearing portion 6, the driving member 4 drives the connecting block 3, and the connecting block 3 drives the cutting knife 5 to move up and down. The slider 2 cooperates with the slide rail 101 on the inner side of the fixed edge. The connecting block 3 is fixedly connected to the side of the slider 2 facing away from the slide rail 101. The driving member 4 is connected to the connecting block 3. The cutting knife 5 is fixedly connected to the lower end of the connecting block 3. The bearing portion 6 is located below the cutting knife 5, and a part of the bearing portion 6 passes through the first opening 102 of the fixing plate 1, so that the structure of the cutting mechanism is simple and the working space is saved.

[0038] In this embodiment, as Figure 2 shown, the driving member 4 is located above the connecting block 3. The cutting mechanism further includes a top plate 7, which is fixedly connected to the top edge of the inner side of the fixing plate 1. The top plate 7 can provide an installation position for the driving member 4 and can shield the top of the cutting mechanism to ensure safety.

[0039] Specifically, a part of the fixed end of the driving member 4 is fixedly located above the top plate 7, and the moving end of the driving member 4 is connected to the connecting block 3 and is located below the top plate 7. The driving member 4 can be a motor, a cylinder, or other power elements, and the present application does not make a unique limitation on this.

[0040] As Figure 2 shown, the cutting mechanism further includes two side plates 8, which are fixedly connected to the side edges of the inner side of the fixing plate 1, and the top ends of the side plates 8 are fixedly connected to the top plate 7. The two side plates 8 can shield part of the side of the cutting mechanism to ensure safety.

[0041] Specifically, the side plate 8 is provided with a second opening 81, and the projection of the second opening 81 on the vertical plane overlaps with that of the first opening 102. The second opening 81 can facilitate the staff to observe the working condition of the internal cutting knife 5 from the outside and can also reduce the weight of the mechanism.

[0042] As Figure 1 shown, the cutting mechanism further includes a baffle 9, which is located on the side of the side plate 8 away from the fixing plate 1. The baffle 9 can shield the remaining side of the cutting mechanism to ensure safety. The two sides of the baffle 9 are respectively fixedly connected to the two side plates 8, and there is a predetermined distance between the bottom end of the baffle 9 and the bearing portion 6, and the predetermined distance is greater than the thickness of the workpiece, so as to facilitate the workpiece to be inserted from the predetermined distance and placed on the bearing portion 6.

[0043] Preferably, the cutting mechanism further includes a detector 10 fixedly arranged on the side of the baffle 9 away from the fixed plate 1. The detector 10 can be used to detect whether there is a workpiece on the bearing part 6 or the position of the workpiece on the bearing part 6, so as to improve the cutting accuracy. The detector 10 can be electrically connected to the driving part 4.

[0044] To improve the accuracy of this cutting mechanism, the number of slide rails 101 is set to two, and the number of corresponding sliders 2 is also two, so as to ensure that the moving direction of the cutting knife 5 is more accurate and improve the cutting accuracy.

[0045] As Figure 2 shown, the cutting mechanism further includes a bottom plate 11, and the bearing part 6 is fixedly arranged on the top surface of the bottom plate 11. The bottom ends of the fixed plate 1 and the side plate 8 are both fixedly connected to the bottom plate 11. The bottom plate 11 not only provides an installation position for the bearing part 6, but also can install the cutting mechanism on other working surfaces, increasing the application scenarios of this cutting mechanism.

[0046] As Figure 3 shown, the bearing part 6 includes a first bearing plate 61 and a second bearing plate 62, and there is a gap 63 between the first bearing plate 61 and the second bearing plate 62. The gap 63 is located directly below the cutting knife 5, so as to ensure the smooth progress of cutting, avoid contact between the cutting knife 5 and the bearing part 6, protect both the cutting knife 5 and the bearing part 6 at the same time, and can extend the service life of the cutting knife 5.

[0047] As Figure 4 shown, the top surface of the first bearing plate 61 slopes downward in the part close to the second bearing plate 62, and the top surface of the second bearing plate 62 slopes upward in the part close to the first bearing plate 61. The highest point of the second bearing plate 62 is flush with the part of the first bearing plate 61 away from the second bearing plate 62, which further protects the bearing part 6 and makes it more labor-saving for the cutting knife 5 to cut the workpiece. The part of the first bearing plate 61 away from the second bearing plate 62 is a plane, and this plane and the highest point of the second bearing plate 62 jointly support the workpiece.

[0048] It should be noted that in the description of this specification, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects, and there is no sequence between them, nor can they be understood as indicating or implying relative importance. In addition, in the description of this specification, unless otherwise specified, the meaning of "a plurality" is two or more.

[0049] Any numerical values recited herein include all values from the lower value to the upper value incremented by one unit therebetween, provided that there is a separation of at least two units between any lower value and any higher value. For example, if a value for the number of components or a process variable (such as temperature, pressure, time, etc.) is recited as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc. are also expressly recited in this specification. For values less than 1, a unit is suitably considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples of what is intended to be specified, and all possible combinations of numerical values recited between the lowest value and the highest value are to be considered to be expressly recited in this specification in a similar manner.

[0050] Unless otherwise indicated, all ranges include the endpoints and all numbers therebetween. The term “about” or “approximate” used in connection with a range is applicable to both endpoints of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, including at least the specified endpoints.
