Description

Technical Field

[0001] The utility model relates to an auxiliary device for quick-freezing equipment, in particular to an anti-turnover alarm switch for a spiral quick-freezing machine. Background Art

[0002] The spiral quick freezer is a quick freezing device. The transmission mesh belt installed on it is driven by a rotating hub and cooperates with the guide rail to drive the material to spiral upward motion, and quickly freeze the material during the upward process. During the operation of a traditional spiral quick freezer, the conveyor belt may be twisted, and in severe cases, the belt may flip, causing the equipment to fail to operate. In order to avoid the above problems, the traditional way is to set multiple electromagnetic induction switches on the equipment, but because the working environment of the equipment is a low-temperature environment, the electromagnetic induction switch works in this environment, which is prone to false alarms, wire damage and other problems due to frost and other reasons. Almost all electronic induction devices have similar problems in low-temperature environments.

[0003] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0004] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes an anti-turnover alarm switch which has a simple structure, ingenious design, reasonable layout and adopts a mechanically triggered structure to realize a turnover alarm.

[0005] The technical solution of the utility model is: an anti-turnover alarm switch for a spiral quick-freezing machine, characterized in that: the alarm switch comprises a housing 1, a swinging member 3 is rotatably supported by a rotating shaft 2 in the housing 1, one end of the swinging member 3 is provided with a concave-shaped portion 4 located outside the housing 1, and the other end is provided with a limiting column 5, the limiting column 5 is movably connected to an arc groove 6 opened on the housing 1,

[0006] An insulating block 7 is also provided in the shell 1, and a terminal 8 is provided on the insulating block 7. A fuse 9 is wound around the terminal 8. One end of the fuse 9 is an outlet connector 10, and the outlet connector 10 is located outside the shell 1. The other end of the fuse 9 passes through a through hole provided on the limit column 5 and is connected to an inlet connector 11. The inlet connector 11 is also located outside the shell 1. The outlet connector 10 and the inlet connector 11 are connected to the alarm circuit through a wire.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] This type of spiral quick-freezer anti-turnover alarm switch has a simple structure, ingenious design, and reasonable layout. It is designed to solve the problem that traditional sensor-type alarm switches are prone to failure in low-temperature environments. It adopts a special structure. When the overturned conveyor belt moves to the alarm switch, it will trigger the swinging part to swing. When the swinging part swings, it will break the fuse in the alarm circuit, and the alarm circuit will be triggered, thereby issuing a warning message to remind the staff to check and intervene in time to ensure that the spiral quick-freezer can work normally. It adopts a mechanical structure to detect the overturning state of the conveyor belt, and it can still work normally in a low-temperature environment; and its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of an embodiment of the utility model.

[0010] Figure 2 It is a schematic diagram of the working state of an embodiment of the utility model. DETAILED DESCRIPTION

[0011] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings: Figure 1 , Figure 2 As shown, an anti-turnover alarm switch for a spiral quick-freezer comprises a shell 1 as a base, a swinging member 3 is rotatably supported by a rotating shaft 2 in the shell 1, one end of the swinging member 3 is provided with a concave portion 4 located outside the shell 1, and the other end is provided with a limiting column 5, and the limiting column 5 is movably connected to an arc groove 6 opened on the shell 1.

[0012] An insulating block 7 is also provided in the shell 1, and a terminal 8 is provided on the insulating block 7. A fuse 9 is wound around the terminal 8. One end of the fuse 9 is an outlet connector 10, and the outlet connector 10 is located outside the shell 1. The other end of the fuse 9 passes through a through hole provided on the limit column 5 and is connected to an inlet connector 11. The inlet connector 11 is also located outside the shell 1. The outlet connector 10 and the inlet connector 11 are connected to the alarm circuit through a wire.

[0013] The working process of the anti-turnover alarm switch for spiral quick freezer of the utility model embodiment is as follows: a plurality of the devices are installed on the spiral quick freezer, each device corresponds to a circle of conveyor belt, that is, the edge of the conveyor belt is located in the concave part 4 on the swinging member 3,

[0014] Under normal working conditions, the conveyor belt of the screw conveyor runs smoothly, and the edge of the conveyor belt is located in the idle part of the concave part 4 and does not contact the concave part 4; when a section of the conveyor belt turns over due to various reasons, when the section of the conveyor belt moves to a certain anti-turnover alarm switch, the turned part collides with the upper or lower part of the concave part 4, and the swing member 3 swings around the rotating shaft 2 after receiving external force;

[0015] When the swing member 3 swings, the limit column 5 at its front end also moves accordingly and moves in the arc groove 6. Since the fuse 9 is connected to the through hole opened on the limit column 5, the limit column 5 will drive the fuse 9 to move together (pull the fuse 9) when it moves. However, since a part of the fuse 9 is wound around the terminal 8, when the swing member 3 swings, the fuse 9 between the limit column 5 and the terminal 8 will be broken. When the fuse 9 is broken, the alarm circuit detects that this current is disconnected, and it will trigger the sound and light alarm device connected to it to work, reminding the staff to check and intervene in time.

[0016] When a certain anti-turnover alarm switch is triggered, after the conveyor belt is processed, a fuse 9 is reinstalled in the alarm switch, and the switch can work normally.
