Description

Technical Field

[0001] This utility model relates to the field of slicing machine technology, and in particular to an EPDM sheet slicing machine. Background Technology

[0002] Sheet slicing machines, also known as flat slicing machines, typically employ fully automatic digital control. They cut materials of varying thicknesses by setting parameters through a control box. Their worktables are made of stainless steel and equipped with a suction system to prevent material slippage during cutting. They are easy to operate and offer high cutting precision.

[0003] Currently, in the production and processing of EPDM sheets, a slicing machine is needed to cut thick EPDM sheets into multiple thinner sheets.

[0004] In the existing EPDM sheet slicing process, due to the structural limitations of the top curvature of the slicing machine's blade, after each cut, it is necessary to wait for the blade to rise and reset and the worktable to return to reset before the next feed and slicing can be carried out. It is impossible to feed continuously after a single slicing and perform a second slicing during the return stroke. This intermittent operation results in low EPDM sheet production efficiency. Therefore, an EPDM sheet slicing machine is proposed. Utility Model Content

[0005] This utility model is an EPDM sheet slicing machine proposed to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an EPDM sheet slicing machine, comprising a sheet slicing machine body, wherein gear assemblies are provided on both sides of the inner wall of the lifting platform of the sheet slicing machine body, and the two gear assemblies are symmetrically arranged, and a first rack and a second rack arranged in parallel are meshed on both sides of the two gear assemblies.

[0007] A first blade holder is fixedly connected to one adjacent side of the outer surface of each of the two first toothed racks, and a first slicing blade is detachably and fixedly installed on both of the two first blade holders.

[0008] A second blade holder is fixedly connected to one adjacent side of the outer surface of each of the two second racks, and a second slicing blade is detachably and fixedly installed on both of the two second blade holders.

[0009] An electric lifting assembly is installed between the two second racks and the lifting platform of the sheet slicing machine body.

[0010] Furthermore, both gear assemblies include a first bearing housing, which is fixedly installed on the inner wall of the lifting platform of the sheet slicing machine body. The inner ring of the bearing built into the first bearing housing is fixedly connected to the gear body, and the gear body is meshed with the adjacent first rack and second rack. This structural design ensures the smoothness of gear transmission.

[0011] Furthermore, the two first blade holders are fixed to the first slicing blade by bolts, and the two second blade holders are also fixed to the second slicing blade by bolts. The bolt connection method not only facilitates the quick replacement and maintenance of the blades, but also ensures the firmness and stability of the blade installation.

[0012] Furthermore, guide rails are slidably connected to one side of the outer surface of both the first and second racks, and the guide rails are fixedly connected to the lifting platform of the sheet slicing machine body. The setting of the guide rails effectively restricts the movement trajectory of the racks and prevents the racks from deviating or getting stuck during movement.

[0013] Furthermore, the electric lifting assembly includes a second bearing seat, which is fixedly installed on the top of the outer wall of the lifting platform of the sheet slicing machine body. A motor is fixedly installed on the top of the second bearing seat, and a screw is fixedly connected to the drive end of the motor. The inner ring of the bearing built into the second bearing seat is fixedly sleeved on the outer surface of the screw. The second bearing seat provides support for the screw, which facilitates the installation of the screw.

[0014] Furthermore, the outer surface of the screw is threaded with a movable frame, and the movable frame is fixedly connected to the two first racks. The movable frame facilitates the synchronous movement of the two first racks.

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

[0016] In use, this utility model is an EPDM sheet slicing machine. Through the setting of a gear assembly, a first rack, a second rack, a first cutter holder, a second cutter holder, a first slicing blade, a second slicing blade, and an electric lifting assembly, the slicing blade can be switched to achieve continuous feeding without complete reset after a single slicing. During the return stroke, another slicing blade performs a secondary cut, thereby forming a continuous slicing operation and improving the production efficiency of EPDM sheets.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, an EPDM sheet slicing machine is disclosed, comprising a sheet slicing machine body 1. Gear assemblies are provided on both inner walls of the lifting platform of the sheet slicing machine body 1, and the two gear assemblies are symmetrically arranged. Parallel first racks 2 and second racks 14 are meshed on both sides of the two gear assemblies. Both gear assemblies include a first bearing seat 15, and the first bearing seat 15 is fixedly installed on the inner wall of one side of the lifting platform of the sheet slicing machine body 1. The inner ring of the bearing inside the first bearing seat 15 is fixedly connected to a gear body 8, and the gear body 8 is meshed with the adjacent first rack 2 and second rack 14. The first bearing seat 15 provides support for the gear body 8, which facilitates the installation of the gear body 8 and reduces the rotational resistance of the gear body 8.

[0025] Two first racks 2 are each fixedly connected to a first blade holder 13 on one adjacent side of their outer surfaces. The two first blade holders 13 are detachably and fixedly mounted with a first slicing blade 10. Two second racks 14 are each fixedly connected to a second blade holder 12 on one adjacent side of their outer surfaces. The two second blade holders 12 are detachably and fixedly mounted with a second slicing blade 9. The two first blade holders 13 are fixed to the first slicing blade 10 by bolts 11, and the two second blade holders 12 are also fixed to the second slicing blade 9 by bolts 11. The bolt 11 connection method facilitates the quick replacement and maintenance of the first slicing blade 10 and the second slicing blade 9.

[0026] Guide rails 7 are slidably connected to one side of the outer surface of the two first racks 2 and the second rack 14, and the guide rails 7 are fixedly connected to the lifting platform of the sheet slicing machine body 1.

[0027] An electric lifting assembly is installed between the two second racks 14 and the lifting platform of the sheet slicing machine body 1. The electric lifting assembly includes a second bearing seat 5, which is fixedly installed on the top of the outer wall of the lifting platform of the sheet slicing machine body 1. A motor 6 is fixedly installed on the top of the second bearing seat 5, and a screw 3 is fixedly connected to the drive end of the motor 6. The inner ring of the bearing built into the second bearing seat 5 is fixedly sleeved on the outer surface of the screw 3. A movable frame 4 is threaded onto the outer surface of the screw 3, and the movable frame 4 is fixedly connected to the two first racks 2. The thread helix angle of the screw 3 is smaller than the friction angle, so that the screw 3 has a self-locking ability and can avoid displacement due to vibration or load.

[0028] Working principle: First, the EPDM sheet is placed on the worktable of the sheet slicing machine body 1. The sheet slicing machine body 1 operates (the operating principle is the same as that of the BRJX-G flat slicing machine). The sheet slicing machine body 1 fixes the EPDM sheet on the worktable through the suction device. Then, the lifting platform adjusts the first slicing blade 10 at the cutting position to descend and feed until it reaches the preset position. Then, the worktable moves the EPDM sheet. When it passes the first slicing blade 10, it is sliced. After the stroke is completed, the motor 6 runs. The motor 6 drives the screw 3 to rotate. The screw 3 drives the movable frame 4 and the two first racks 2 to rise. At the same time, the first racks 2 rise and drive the first slicing blade 10 to rise through the first blade holder 13. At this time, the second rack 14 descends under the action of the gear body 8. The second rack 14 drives the second slicing blade 9 to descend to the predetermined position through the second blade holder 12. At the same time, the lifting platform feeds. Then, the worktable returns to its original position, driving the EPDM sheet to reset. When the EPDM sheet passes the second slicing blade 9, it is sliced.

[0029] It should be noted that, in actual use, the motor 6 is electrically connected to the controller used by the sheet slicing machine body 1 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that this hardware structure improvement can achieve in conjunction with common knowledge.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
