DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] like Figure 1 and Figure 3As shown, a cutting device for chemically stable weather-resistant PP modified materials comprises a workbench 1, with horizontal plates 2 symmetrically fixedly connected to both sides of the upper surface of the workbench 1, a rotating gantry 3 fixedly installed between the two horizontal plates 2, the rotating gantry 3 comprising a first vertical rod 31 and a second vertical rod 32 respectively fixedly connected to the upper surfaces of the two horizontal plates 2, a motor 33 embedded and fixedly installed inside the top of the first vertical rod 31, a horizontal rod 34 fixedly connected to the output shaft of the motor 33, and the detachable cutting mechanism 4 penetrates and is installed on the top of the horizontal rod 34. An opening 35 matching with the horizontal rod 34 is provided on one side of the top of the second vertical rod 32, an electric push rod 36 is fixedly installed on the inner top of the opening 35, a positioning block 37 is fixedly connected to the bottom end of the electric push rod 36, and a positioning hole 38 matching with the positioning block 37 is provided on the upper surface of one end of the horizontal rod 34.

[0023] When the detachable cutting mechanism 4 needs to be maintained, the electric push rod 36 can be started to move the positioning block 37 out of the positioning hole 38, and then the motor 33 can be started. The rotation of the motor 33 can drive the cross bar 34 to rotate, thereby facilitating the transfer of the detachable cutting mechanism 4 to the outside, so that the maintenance personnel have enough space to operate, thereby solving the problem that the cutting structure of the existing device is installed on the top of the device and the space is limited and it is inconvenient to maintain.

[0024] Embodiment 2:

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a detachable cutting mechanism 4 is installed through the top of the rotary gantry 3, and the detachable cutting mechanism 4 includes a first cylinder 41 that is fixedly installed on the upper surface of the crossbar 34, and a U-shaped mounting seat 42 is fixedly connected to the bottom end of the first cylinder 41, and a bidirectional screw rod 43 is rotatably connected to the inside of the U-shaped mounting seat 42, and the outer surface of the bidirectional screw rod 43 is symmetrically threaded with two L-shaped blocks 44 that are slidably connected to the inner wall of the U-shaped mounting seat 42, and a knife seat 45 is provided below the U-shaped mounting seat 42, and a connecting block 46 is fixedly connected to the top of the knife seat 45, and a card slot 47 that matches the L-shaped block 44 is opened on both sides of the connecting block 46, and a cutting knife 48 is fixedly connected to the bottom of the knife seat 45, and knobs 49 are fixedly connected to both ends of the bidirectional screw rod 43. T-blocks 410 are symmetrically fixedly connected to the upper surface of the knife seat 45, and T-slots that match the T-blocks 410 are symmetrically opened on the lower surface of the U-shaped mounting seat 42. A chemically stable weather-resistant PP modified material body 7 is placed on the upper surface of the workbench 1 , and a cutting knife groove 8 matching with a cutting knife 48 is opened on the upper surface of the workbench 1 .

[0026] When replacing the cutting knife 48, only one knob 49 needs to be turned to drive the bidirectional screw rod 43 to rotate, and the two L-shaped blocks 44 can be driven to move relative to each other and move out of the slot 47 through the thread. At this time, the knife holder 45 will not fall off under the action of the T-block 410 and the T-slot, and then the knife holder 45 and the cutting knife 48 can be removed along the direction of the T-slot for easy use, thereby solving the problem that the existing device needs to hold the knife by hand when disassembling the knife, which not only increases the workload but also makes it easy to fall off.

[0027] Embodiment 3:

[0028] like Figure 1 and Figure 2 As shown, a U-shaped frame 5 is fixedly connected between the two horizontal plates 2, and a limiting mechanism 6 is installed through the outer surface of the U-shaped frame 5. The limiting mechanism 6 includes a second cylinder 61 symmetrically installed through the top of the U-shaped frame 5, and the bottom ends of the two second cylinders 61 are fixedly connected with a pressing plate 62 in contact with the cutting knife 48. Third cylinders 63 are fixedly installed through both sides of the outer surface of the U-shaped frame 5, and one end of the third cylinder 63 is fixedly connected to a limiting plate 64.

[0029] When the chemically stable weather-resistant PP modified material body 7 is cut and transported, the operation of the second cylinder 61 and the third cylinder 63 can respectively drive the pressing plate 62 and the limiting plate 64 to move, so as to limit the top and both sides of the chemically stable weather-resistant PP modified material body 7 to avoid movement.

[0030] Working principle: When in use, place the chemically stable weather-resistant PP modified material body 7 on the workbench 1. The operation of the second cylinder 61 and the third cylinder 63 can respectively drive the pressing plate 62 and the limiting plate 64 to move, so as to limit the top and both sides of the chemically stable weather-resistant PP modified material body 7 to avoid movement. The operation of the first cylinder 41 drives the cutting knife 48 to move downward, and with the cooperation of the cutting knife groove 8, the cutting operation of the chemically stable weather-resistant PP modified material body 7 is realized.

[0031] When the detachable cutting mechanism 4 needs to be maintained, the electric push rod 36 can be started to move the positioning block 37 out of the positioning hole 38, and then the motor 33 can be started. The rotation of the motor 33 can drive the cross bar 34 to rotate, thereby facilitating the transfer of the detachable cutting mechanism 4 to the outside, so that the maintenance personnel have enough space to operate, thereby solving the problem that the cutting structure of the existing device is installed on the top of the device and the space is limited and it is inconvenient to maintain.

[0032] When replacing the cutting knife 48, only one knob 49 needs to be turned to drive the bidirectional screw rod 43 to rotate, and the two L-shaped blocks 44 can be driven to move relative to each other and move out of the slot 47 through the thread. At this time, the knife holder 45 will not fall off under the action of the T-block 410 and the T-slot, and then the knife holder 45 and the cutting knife 48 can be removed along the direction of the T-slot for easy use, thereby solving the problem that the existing device needs to hold the knife by hand when disassembling the knife, which not only increases the workload but also makes it easy to fall off.

[0033] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
