For the connection between the front sleeve 33 and the rotating shaft 31, a pressing connection may be adopted. Or, this embodiment provides a specific implementation manner: the front retaining sleeve fixing assembly is arranged at the front end of the front retaining sleeve 33 and used for fixing the front retaining sleeve 33 and limiting the front retaining sleeve 33 to move along the axial direction.

A specific implementation way is as follows: the front end of the front blocking sleeve 33 is provided with a mounting groove with a forward opening, the center line of the mounting groove is superposed with the center line of the rotating shaft 31, and the opening of the mounting groove is provided with a blocking edge which extends inwards to form. The section of the mounting groove is circular, and the diameter of the mounting groove is larger than that of the rotating shaft 31.

Preceding fender cover fixed subassembly includes: a screw 331, a stop 332 and a locking nut 333. The length direction of the screw 331 is consistent with the length direction of the rotating shaft 31, and the rear end of the screw 331 is fixedly connected to the front end of the rotating shaft 31. For example: a screw hole is formed at the front end of the rotary shaft 31, and the screw 331 is screwed into the screw hole for fixing.

The screw 331 is located to the dog 332 cover, and the rear end of dog 332 is located the mounting groove, and the size of dog 332 is greater than the opening size of mounting groove, is located the mounting groove by the backstop limit. The stopper 332 has a rear end diameter larger than that of the rotation shaft 31.

A locking nut 333 is provided at the front end of the stopper 332 to be screwed with the screw 331. During tightening, the lock nut 333 moves toward the stop 332, axially compressing the stop 332 within the mounting slot and limiting forward movement of the front sleeve 33.

Further, a disc spring 334 is sleeved on the screw rod 331, and the disc spring 334 is located between the stopper 332 and the rotating shaft 31. As the stop 32 moves rearward, the disc spring 334 is compressed to accumulate elastic potential energy. After the front retaining sleeve fixing component is assembled, the rebounding force of the disc spring 334 causes the stop 332 to apply an axial force to the locking nut 333, so that the purpose of preventing the nut from loosening is achieved.

On the basis of the scheme, the rotating shaft 31 is sleeved with the supporting sleeve 36, the supporting sleeve 36 is positioned between the front retaining sleeve 33 and the rear retaining sleeve 34, and the supporting sleeve 36 is in clearance fit with the wire roller 35. During the assembly of the take-up and pay-off device, the wire roller 35 is axially moved from front to back to be sequentially sleeved on the front retaining sleeve 33 and the rear retaining sleeve 34. In the process of not reaching the rear blocking sleeve 34, the supporting sleeve 36 can carry out primary positioning and supporting on the wire roller 35, and the load pressure of an operator is reduced.

The support sleeve 36 can be in a press fit with the rotating shaft 31 and synchronously rotate with the rotating shaft 31 so as to reduce vibration and abnormal sound in the working process.

For the installation of the above-mentioned take-up and pay-off driver 31, the present embodiment also provides a specific implementation manner:

the take-up and pay-off line driver 321 may be mounted to the cutting frame 11 by a motor mount. Specifically, the motor mount includes: a first mounting plate 311 and a second mounting plate 312. The first mounting plate 311 is parallel to the central line direction of the rotating shaft 32 and is located on the side surface of the wire take-up and pay-off driver 31, the upper part of the wire take-up and pay-off driver 31 is mounted on the adjacent surface of the first mounting plate 311 through the fixing seat 313, and the bottom part of the wire take-up and pay-off driver is also fixed to the other surface of the first mounting plate 311 through a connecting piece, so that the stability of the wire take-up and pay-off driver 31 in the working process is improved. The fixing base 313 may be fixed to the first mounting plate 311 by welding, or may be fixed to the first mounting plate 311 by bolts. The take-up and pay-off wire driver 31 may be fixed to the fixing base 313 by bolts.

The second mounting plate 312 is vertically connected to the front end of the first mounting plate 311, and the second mounting plate 312 is provided with a through hole through which the rotary shaft 31 can pass to be connected to the take-up and pay-off line driver 31.

Further, a stopper pin holder 37 is provided on the front end surface of the second mounting plate 312. The stopper pin holder 37 is provided with a pin hole into which the stopper pin is inserted. Beside the latch housing 37, detection means are provided, for example: a proximity sensor, a photoelectric sensor, etc. for detecting whether the stopper pin is inserted into the pin hole. The application scenario of the scheme is as follows: after the microtome stops working, the stop pin can be inserted into the pin hole. When the detection device detects that the stop pin is inserted, a signal is sent to the controller for processing, and the motor is forbidden to rotate. And then, the operations of feeding, discharging, overhauling, maintenance and the like can be performed, the operation safety is improved, and the personal safety of operators is also guaranteed.

Further, a support member may be provided below the wire roll 35 for temporarily supporting the wire roll 35 during the process of assembling the wire roll 35. For example: at least two support rods 38 are arranged side by side on the front end surface of the second mounting plate 312 and below the rotating shaft 31. The support rods 38 extend in the direction of the center line of the rotating shaft 31, and a predetermined gap is formed between the support rods 38. In this embodiment, two support rods 38 are arranged side by side, and the distance between the two support rods 38 is greater than the radius of the wire roller 35 and smaller than the diameter of the wire roller 35, so that the two support rods 38 can temporarily support the wire roller 35.

During the assembly process, since the installation position of the wire roller 35 is higher than the ground, the wire roller 35 can be lifted and placed on the two support rods 38, and then after the front and

rear sleeves

33 and 34 are installed, the wire roller 35 is lifted and installed on the front and

rear sleeves

33 and 34.

In the traditional scheme, the winding and unwinding device is large in size and is usually arranged at the rear end of a slicing machine, and the main roller is arranged at the front end of the slicing machine. The cutting line is wound to the main roller from the wire winding and unwinding device on one side forwards, and then wound to the other wire winding and unwinding device from the other side of the main roller backwards.

One of the drawbacks of the conventional solution, as mentioned above, results in a large volume of the microtome; the second disadvantage is that the distance of the cutting line between the main roller and the take-up and pay-off device is longer, if the tension of the cutting line is smaller, the cutting line is easy to separate from the wire groove on the main roller; if the cutting wire tension is high, there is a high risk of wire breakage, resulting in difficulty in tension control.

Based on the problem, the above-mentioned scheme that this embodiment provided has reduced take-up and pay-off's volume to set up it in the below of main roll, reduced with the distance between the main roll, and then shortened the line distance of walking, reduced the broken string risk, also reduced the tension control degree of difficulty.
