[0029] The slicing machine frame includes a bracket 2 located at one side of a movable cutter head 105 at a slicing machine head, a fixed cutter head 17 used in conjunction with the movable cutter head 105 is installed on the bracket 2, and the fixed cutter head 17 is located on the upper side of the movable cutter head 105. A servo motor 3 is fixed to one side of the bracket 2, and a main feeding wheel 4 is installed at the power output end of the servo motor 3. A driven feeding wheel 5 cooperating with the main feeding wheel 4 is provided on the side of the main feeding wheel 4 facing the movable cutter head 105. The main feeding wheel 4 rotates under the drive of the servo motor 3 and cooperates with the driven feeding wheel 5 to jointly feed materials to the fixed cutter head 17 and the movable cutter head 105; the distance between the driven feeding wheel 5 and the main feeding wheel 4 is adjustable;

[0030] Two symmetrical grooved plates 6 are arranged between the main feed wheel 4 and the driven feed wheel 5, and grooves are provided on opposite sides of the two grooved plates 6 along their longitudinal direction, and the grooves of the two grooved plates 6 together form a feeding channel for slices to pass through, and the existence of the feeding channel can ensure the flatness of the emery cloth pieces sent to the movable cutter head 105 and the fixed cutter head 17, and notches are provided on the opposite sides of the two grooved plates 6, and the notches of the two grooved plates 6 form a space for the main feed wheel 4 and the driven feed wheel 5 to extend into, and the main feed wheel 4 and the driven feed wheel 5 extend into the space at the same time, and the contact point between the main feed wheel 4 and the driven feed wheel 5 is the longitudinal neutral plane of the grooved plate 6, and the distance between the two grooved plates 6 is adjustable.

[0031] In this embodiment, a cylinder 7 is fixed to one side of the bracket 2 on which a servo motor 3 is installed, and an L-shaped rod 8 is connected to the power output end of the cylinder 7, and the other end of the L-shaped rod 8 is connected to a transmission shaft 9, and an L-shaped plate 10 is installed on the other end of the transmission shaft 9. The driven feeding wheel 5 is rotatably installed on the L-shaped plate 10, so that under the drive of the cylinder 7, the distance between the driven feeding wheel 5 and the main feeding wheel 4 is adjusted to adapt to emery cloth sheets of different thicknesses and to facilitate the feeding of newly replaced emery cloth sheets; in order to facilitate the transportation of emery cloth sheets, the outer edges of the main feeding wheel 4 and the driven feeding wheel 5 are provided with a twisted pattern to increase the friction against the emery cloth sheets.

[0032] In this embodiment, a hand-pull valve 11 for controlling the air cylinder 7 is installed on the column of the tensioning mechanism. The hand-pull valve 11 can be an existing product on the market, and is used to adjust the movement direction of the air cylinder 7 and open and close the air circuit. The hand-pull valve is connected to an air circuit interface connected to the air station.

[0033] In this embodiment, two vertical plates 12 are provided on the top of the bracket 2, and a bidirectional screw 13 is passed through the vertical plate 12. The two threaded ends of the bidirectional screw 13 are respectively provided with sliders 14 fixedly connected to the two grooved plates 6. The bottom of the slider 14 is slidably connected to a slide rail 15 fixed on the bracket 2. When the bidirectional screw 13 is rotated, the two sliders 14 are moved closer to or farther away from each other according to the different rotation directions of the bidirectional screw 13, thereby adjusting the spacing between the two grooved plates 6 to realize the transmission of abrasive cloth sheets of different widths.

[0034] In this embodiment, a knob 16 is provided at one end of the bidirectional lead screw 13 to facilitate the rotation operation of the bidirectional lead screw 13 .

[0035] In this embodiment, the two ends of the fixed blade head 17 have downwardly extending grooving blade heads 1701, which extend horizontally to the middle of the grooved plate 6, and the lower end of the grooving blade head 1701 does not contact the base 21, thereby effectively ensuring that the emery cloth can be cut and grooved.

[0036] In this embodiment, a slide groove is provided at the bottom of the movable cutter head 105, and a track 107 matching the slide groove is provided on the base 21, so that when the driving motor 102 drives the movable cutter head 105 to move, the linearity of the movement of the movable cutter head 105 is always maintained, and the movable cutter head 105 will not be skewed during the movement, thereby effectively ensuring the consistency of the movable cutter head 105 and the fixed cutter head 17, and effectively and quickly slicing the emery cloth.

[0037] In this embodiment, a push plate 108 is provided on the side of the movable cutter head 105 facing the bracket 2, and the lower end of the push plate 108 has a certain gap from the base 21, so as to ensure the smooth movement of the push plate 108 back and forth with the movable cutter head 105. The setting of the push plate 108 can push the cut emery cloth pieces, and the push plate 108 pushes the cut emery cloth pieces forward a certain distance, so that when the movable cutter head 105 is pulled back to its original position, when the main feeding wheel 4 and the driven feeding wheel 5 feed downward, the new emery cloth pieces will not be stacked with the cut emery cloth pieces.

[0038] In this embodiment, a photoelectric switch 22 is provided on the upper side of the bracket 2. The photoelectric switch 22 can monitor whether there are emery cloth sheets transmitted to the grooved plate 6. When the photoelectric switch 22 detects no emery cloth sheets, it means that there are no emery cloth sheets that need to be sliced, thereby stopping the operation of the drive motor 102 and the servo motor 3 to stop the slicing operation. In order to facilitate the installation of the photoelectric switch 22, a cover shell is installed on the vertical plate 12 to cover the bidirectional lead screw 13, the slider 14 and the slide rail 15, and the photoelectric switch 22 is fixed on the top of the cover shell.

[0039] In this embodiment, a dust collector 18 is also included, which is arranged on one side of the base 21. The dust collector 18 can be a cyclone dust collector. The dust collector 18 is connected to the dust hood 19 on the lower side of the bracket 2 through a dust suction pipe. The middle part of the dust hood 19 is provided with an air outlet circular pipe 20 connected to the dust suction pipe, so that the dust generated during the slicing operation can be removed through the dust collector 18 to avoid pollution to the production environment.

[0040] In the specific implementation of the present invention, a PLC controller is also provided on one side of the base 21, and the PLC controller is connected to the drive motor 102, the servo motor 3, the photoelectric switch 22, and the dust collector 18 through a signal line, so that the PLC controller can receive the monitoring signal of the photoelectric switch 22, and judge whether there is raw material of emery cloth sheets fed into the grooved plate 6. If it is monitored that no raw material of emery cloth sheets is fed into the grooved plate 6, the PLC controller will send a stop operation instruction to the drive motor 102, the servo motor 3, and the dust collector 18, and then the drive motor 102 pulls the moving cutter head 105 to restore to the initial position closest to the drive motor 102; in other embodiments, the dust collector 18 can also be configured with a control switch, and its start and stop are directly controlled by the control switch.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
