Description

Technical Field

[0001] The utility model relates to the technical field of detection mechanisms, and particularly relates to a detection mechanism for the shape of materials at the inlet and outlet of a lift. Background Art

[0002] The wide application of automated equipment has greatly improved production efficiency; however, the problem of inconsistent material specifications in the production process, especially the entry of oversized materials such as over-width and over-height, may lead to problems such as equipment jamming, damage, or even shutdown, thereby affecting the operation efficiency and safety of the production line; therefore, it is very necessary to install a set of material shape detection mechanism at the inlet and outlet of the lift or conveyor system; the main function of this detection mechanism is to monitor whether the materials entering the equipment meet the predetermined size requirements and prevent abnormal materials from entering the equipment, causing failures and shutdowns.

[0003] Most of the existing shape detection methods rely on electronic sensors or vision detection systems; although these systems can achieve high-precision detection, their costs are relatively high, and there are adaptability problems for complex production environments (such as dust, vibration, etc.), and false alarms or missed alarms are likely to occur. At the same time, such systems often require regular maintenance and may face problems such as software upgrades and sensor aging in actual use.

[0004] Therefore, in view of the problem of oversized material dimensions at the inlet and outlet of the lift, this application proposes a detection mechanism for the shape of materials at the inlet and outlet of the lift, which does not require a complex electrical or sensor system, reduces the failure rate of the equipment, ensures the stability of long-term use, and can also reduce production costs and maintenance difficulties, and has important application value.

Therefore, it should not be construed as a limitation to the present utility model.

[0036] This application proposes a detection mechanism for the shape of materials at the inlet and outlet of a lift, which is as follows:

[0037] For reference Figure 1 , this application mainly consists of a machine frame 1 provided on a conveyor at the inlet and outlet of the lift, two groups of four support seats 2 symmetrically provided on the machine frame 1, two groups of symmetrically - provided limit components 3 with both ends rotatably connected to the support seats 2, a travel switch 4 fixedly installed on the machine frame 1, and a number - issuing block 5 provided on the limit component 3 and docked with the travel switch 4; through the cooperation between the above - mentioned structures, the situation where the incoming products are over - wide or over - high can be prevented.

[0038] For reference Figure 1 , in order to facilitate the installation of the remaining structures, the machine frame 1 is set to include two parts: two frames 11 and a pull rod 12; the two frames 11 are symmetrically arranged, and a pull rod 12 is detachably provided at the top of the two frames 11. After removing the pull rod 12, it is beneficial for the subsequent installation, fixation and adjustment of the limit component 3.

[0039] For reference Figure 1, there are four support seats 2, which are divided into two groups. The two groups are symmetrically arranged on two frames 11. One group of support seats 2 on one frame 11 is distributed vertically at both ends of the frame 11.

[0040] For reference Figure 1 , there are two groups of limit components 3, and the two groups are respectively rotatably connected to the two groups of support seats 2; the limit component 3 includes a rotating rod 31, a connecting shaft 32 and a limit rod 33. Both ends of the rotating rod 31 are rotatably connected to the support seat 2 through a rotating shaft. The connecting shaft 32 is arranged on the rotating rod 31, and the limit rod 33 is arranged at one end of the connecting shaft 32 away from the rotating rod 31; when an over-width or over-height product passes through the limit component 3, the limit rod 33 is stressed, and at this time the rotating rod 31 rotates on the support seat 2;

[0041] For reference Figure 1 And Figure 4 , in order to promote the reset effect after the limit rod 33 is out of stress, a torsion spring 311 is arranged at the bottom of the rotating rod 31, and the rotating reset effect is realized through the torsion spring 311.

[0042] For reference Figure 1-2 , in order to make further adjustments according to different detection situations, the connecting shaft 32 is further arranged. The connecting shaft 32 includes a fixing plate 321, a moving plate 322 and a connecting column 323. The fixing plate 321 is fixedly connected to the rotating rod 31. The moving plate 322 is adjustably connected to the fixing plate 321 through bolts, and the surface of the connecting column 323 is connected and fixed to the moving plate 322; by adjusting the moving plate 322 on the fixing plate 321, the distance between the limit rod 33 and the rotating rod 31 is changed after adjustment; thereby promoting the connection distance between the left and right limit rods 33 to become larger or smaller; when adjusting the height limit of the limit rod 33, the limit rod 33 is inserted into one end of the connecting column 323 and adjusted up or down, and then fixed again to complete the debugging; further, in order to ensure the stability of the connection between the connecting shaft 32, the rotating rod 31 and the limit rod 33, two connecting shafts 32 are arranged on one rotating rod 31.

[0043] For reference Figure 3-4 , when the rotating rod 31 rotates, it will trigger the relative movement of the signal sending block 5 arranged on the rotating rod 31. Also, because the signal sending block 5 is docked with the travel switch 4, when the signal sending block 5 changes, the travel switch 4 is activated, thereby prompting the system connected to the travel switch 4 to send out an alarm message.

[0044] In the present utility model, the working steps of the device are as follows:

[0045] 1. First, the product is transported to the lower side of the machine frame 1 through the conveyor;

[0046] 2. Secondly, when the width and height of the product exceed the original setting, apply force to the limiting rod 33, and at this time, the rotating rod 31 rotates;

[0047] 3. Then, during the rotation of the rotating rod 31, it will drive the signal-issuing block 5 to move, and thus the movement of the signal-issuing block 5 will cause the travel switch 4 to turn on, and at this time, the connected alarm device emits an alarm signal;

[0048] 4. Finally, after being processed, the alarm signal stops, the thrust borne by the rotating rod 31 disappears, and the torsion spring 311 drives the rotating rod 31 to reset, and continuous subsequent detection is carried out.

[0049] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope claimed by the present utility model. The scope claimed by the present utility model is defined by the appended claims and their equivalents.
