Detailed implementation manners

[0022] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0023] As Figures 1 to 5 shown, a safety interlock device for the protective cover of a slicer of the present utility model includes:

[0024] A slicer body 1 and a travel switch 5 are provided. A protective cover 2 is arranged on the slicer body 1. The protective cover 2 is located in the cutting area of the slicer body 1. A transparent baffle 3 is arranged at the notch of the protective cover 2 through a connection assembly. A notch is provided at the connection between the transparent baffle 3 and the protective cover 2. An installation member 4 is arranged on one side inside the protective cover 2. A long slot hole is arranged on the installation member 4. A screw 6 is arranged in the threaded hole of the travel switch 5. The screw 6 passes through the long slot hole of the installation member 4 and is connected to the screw 6. The transparent baffle 3 is in contact connection with the travel switch 5. The travel switch 5 is connected to the control module of the slicer body 1 through a communication line. The control module of the slicer body 1 controls the operation of the cutting knife in the cutting area. That is, when the transparent baffle 3 is separated from the contact with the travel switch 5, the operation of the cutting knife in the cutting area stops. This device ensures the safety of the operator by installing a transparent baffle 3 at the notch of the protective cover 2 and making it in contact connection with the travel switch 5. Once the transparent baffle 3 is opened or displaced, the travel switch 5 is immediately triggered, thereby quickly cutting off the power supply of the cutting knife, effectively avoiding the risk of personal injury caused by the exposure of the cutting area, greatly improving the operation safety of the equipment. Due to the instant response mechanism designed in the device, only when the protective cover 2 is correctly closed, the cutting knife in the cutting area of the slicer body 1 is allowed to operate. This not only avoids the production interruption caused by safety accidents, but also prompts the operator to develop good safety operation habits, indirectly improving the continuity and efficiency of production operations. The design of the transparent baffle 3 enables the operator to directly observe the working state inside the slicer without opening the protective cover, facilitating daily monitoring and maintenance. The connection method of the long slot hole on the installation member 4 and the travel switch 5 through the screw 6 provides convenience for adjusting the position. The notch is provided at the connection between the transparent baffle 3 and the protective cover 2 to facilitate the removal of the slice. The installation has a high protection coefficient and reduces the operating cost.

[0025] As Figures 1 to 5As shown in the figure, as a preferred solution, the connecting component includes multiple groups of fixing parts 7 arranged on the protective cover 2. There are at least two groups of fixing parts 7. A connecting part 8 is arranged inside the shaft hole of the fixing part 7. An auxiliary part 9 is arranged on the connecting part 8. Multiple groups of auxiliary parts 9 are all arranged on the transparent baffle 3. Multiple groups of connecting parts 8 are driven by a power component; by adopting the design of multiple groups of fixing parts 7 and connecting parts 8, and the layout of the auxiliary parts 9 on the transparent baffle 3, the device constructs a stable connection system. This multi-point support structure ensures a more firm connection and rotational support between the protective cover 2 and the transparent baffle 3, and facilitates the opening and rotation of the transparent baffle 3. The multiple groups of connecting parts 8 driven by the power component make the opening and closing of the protective cover 2 easier and faster.

[0026] As Figures 1 to 5 shown in the figure, as a preferred solution, the power component includes a driving motor 10 arranged inside the protective cover 2. Coaxial transmission shafts 11 are arranged on two adjacent connecting parts 8. Sprockets 12 are coaxially arranged on the output end of the driving motor 10 and the transmission shaft 11 respectively. A chain 13 is arranged in a meshing manner on the two sprockets 12. An isolating part 14 is arranged on the protective cover 2. The chain 13 is located in the inner cavity of the isolating part 14; the driving motor 10 integrated inside the protective cover 2 provides an automated solution for the opening and closing operation of the protective cover. Through motor drive, the rapid and stable opening and closing of the protective cover are realized, and at the same time, it prevents the transparent baffle 3 from freely contacting the travel switch 5 to cause a virtual connection and short circuit of the device. The design of the transmission shafts 11 on two adjacent connecting parts 8, and the matching sprockets 12 and chain 13 constitute an efficient transmission system. The driving motor 10 drives the transparent baffle 3 to open and close. The setting of the isolating part 14 and the layout of the chain 13 in its inner cavity effectively isolate the direct contact between the transmission components and the external environment, avoiding potential safety hazards caused by foreign object intrusion or accidental contact by personnel.

[0027] As Figures 1 to 5 shown in the figure, as a preferred solution, a start switch 15 is arranged on the protective cover 2. The start switch 15 is electrically connected to the driving motor 10 in a controlled manner; the integration of the start switch 15 enables the operator to directly control the start and stop of the driving motor 10 on the protective cover 2 without having to search for or operate other remote control devices additionally, greatly improving the convenience and efficiency of use.

[0028] As Figures 1 to 5 shown in the figure, as a preferred solution, a limiting part 16 is arranged inside the protective cover 2. The transparent baffle 3 is in contact connection with the limiting part 16; the flipping interval of the transparent baffle 3 is limited by the limiting part 16. This design protects the travel switch 5 and prevents the transparent baffle 3 from applying excessive pressure on the travel switch 5 and causing damage.

[0029] As Figures 1 to 5As shown, as a preferred solution, the sprocket 12 is rotatably connected to the transmission shaft 11, and a damping pad is provided at the rotational connection. The rotational friction between the sprocket 12 and the transmission shaft 11 is greater than the flipping force of the transparent baffle 3. Through the design of the damping pad, the driving motor 10 drives the opening and closing of the transparent baffle 3. Through the rotational connection between the sprocket 12 and the transmission shaft 11, the driving motor 10 is protected after the transparent baffle 3 contacts the limiting member 16.

[0030] As Figures 1 to 5 shown, as a preferred solution, an inner groove is provided on the transparent baffle 3, and an extension member 17 is provided in the inner groove of the transparent baffle 3. Through the extension member 17, the transparent baffle 3 and the notch of the protective cover 2 are blocked to provide isolation and dust protection in the non-working state of the device.

[0031] As Figures 1 to 5 shown, as a preferred solution, multiple sets of threaded posts 18 are provided on the extension member 17. At least one set of threaded posts 18 is provided. The threaded posts 18 pass through the adjustment slots of the transparent baffle 3. Nuts 19 are provided on the threaded posts 18, and adjustment rods 20 are provided on the nuts 19. Through the cooperation of the threaded posts 18 and the nuts 19, the connection position between the extension member 17 and the transparent baffle 3 is locked, and through the adjustment rod 20, the relative rotation difficulty between the nut 19 and the threaded post 18 is reduced.

[0032] As Figures 1 to 5 shown, as a preferred solution, its working process is as follows:

[0033] When the equipment is working normally, the transparent baffle 3 is close to the notch of the protective cover 2, and the travel switch 5 is in a touch connection state. At this time, the cutting tool in the cutting area of the slicer body 1 starts to work normally. When the protective cover 2 needs to be opened, the start switch 15 is pressed. After the driving motor 10 receives the start signal, it starts to work. The output end of the motor 10 transmits power to multiple sets of connecting members 8 through the transmission system composed of the sprocket 12 and the chain 13. These connecting members 8 cooperate with the auxiliary members 9 on the transparent baffle 3 to drive the transparent baffle 3 to rotate and open smoothly. At the same time, the travel switch 5 is separated from the transparent baffle 3, and the trigger signal is transmitted to the control module of the slicer body 1. After receiving the signal, the control module turns off the cutting tool in the cutting area. When the protective cover 2 is closed, the operator operates the start switch 15 again, and the driving motor 10 rotates in reverse to drive the transparent baffle 3 to close through the transmission system until it touches and reconnects with the travel switch 5, and the cutting tool then stops working. During this process, when the transparent baffle 3 contacts the limiting member 16, the relative rotation between the sprocket 12 and the transmission shaft 11 protects the driving motor 10.

[0034] For a safety interlock device of the slicer protective cover of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0035] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
