Description

Technical Field

[0001] This utility model relates to the technical field of PLC safety control devices, and in particular to a PLC safety control device for a small meat grinder. Background Technology

[0002] Small meat grinders are kitchen or food processing equipment used to grind meat and other ingredients. PLC is an industrial control computer with features such as flexible programming, high reliability, and strong anti-interference ability. Existing PLC safety control devices are usually separated from meat grinders, which is cumbersome to use. Therefore, a PLC safety control device for small meat grinders is needed.

[0003] Chinese patent provides a low-voltage safety control device based on PLC, publication number CN112000060A, including a housing, control buttons and control switches installed on the surface of the housing, a cover plate fixedly connected to the back of the housing by screws, a mounting box contacting one side surface of the cover plate, the surface of the mounting box being fixedly connected to the inner wall of the housing, the mounting box having a mounting groove, the inner wall of the mounting groove having radially symmetrical mounting holes, a fixing rod being threadedly connected to the mounting holes, and a cooling fan being axially slidably sleeved on the surface of the fixing rod.

[0004] The device described above has a shock-absorbing function through the shock-absorbing springs and shock-absorbing sleeves, which greatly reduces the vibration force generated by the operation of the cooling fan. However, when using this device, the PLC controller cannot be directly installed on the outside of the meat grinder. Other tools are needed to fix the mounting box to the outer wall of the meat grinder. Furthermore, the PLC controller is prone to displacement or damage due to vibration or misoperation during the operation of a small meat grinder. Utility Model Content

[0005] The main purpose of this utility model is to provide a PLC safety control device for a small meat grinder, which can effectively solve the technical problem in the background art that the PLC controller cannot be directly installed on the outside of the meat grinder and that other tools are needed to fix the mounting box to the outer wall of the meat grinder.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A PLC safety control device for a small meat grinder includes a placement box, inside which a PLC controller is placed. Fixing blocks are fixedly installed on the left and right outer walls and the front and rear outer walls of the placement box, and sliding grooves are formed on the inner walls of the four fixing blocks.

[0008] As a further embodiment of this utility model, the top of the placement box is provided with a cover plate, and connecting blocks are fixedly installed on the left and right outer walls and the front and rear outer walls of the cover plate. The outer walls of the four connecting blocks are slidably connected to the outer walls of the sliding groove.

[0009] As a further embodiment of this utility model, four limiting blocks are fixedly installed at the bottom of the cover plate, and the limiting blocks are located at the top of the PLC controller.

[0010] As a further embodiment of this utility model, a clamping plate is fixedly installed at the bottom of the placement box, and two screws are provided on the right side of the top of the clamping plate, with the outer wall of the screws threadedly connected to the outer wall of the clamping plate.

[0011] As a further embodiment of this utility model, the clamping plate is provided with two connecting plates inside, and one end of each of the two connecting plates is rotatably connected to the outer wall of the clamping plate.

[0012] As a further embodiment of this utility model, anti-slip plates are provided on one outer wall of both connecting plates, and the anti-slip plates are fixedly connected to the connecting plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) The PLC safety control device of this small meat grinder has a PLC controller placed inside the placement box. When the cover is placed on the placement box, the four connecting blocks slide along the sliding groove. When the sliding reaches the bottom, it can no longer slide. The limit block at the bottom of the cover can hold the bottom of the PLC controller in place. The PLC controller is firmly fixed inside the placement box, which effectively prevents the PLC controller from shifting or being damaged due to vibration or misoperation during the operation of the small meat grinder.

[0015] 2) The PLC safety control device of this small meat grinder opens the two connecting plates inside the clamping plate, and then inserts the clamping plate into one side of the small meat grinder. The protective plate can fit against the outer wall of the small meat grinder. Through the threaded connection between the outer wall of the screw and the outer wall of the clamping plate, rotating the screw can make the screw move downward and keep it in contact with the outer wall of the small meat grinder, thereby fixing the PLC controller in place. Moreover, the anti-slip plate can effectively increase the friction with the outer wall of the small meat grinder, preventing the PLC controller from shaking or falling off during use, thus ensuring its stability and safety.
