Description

Technical Field

[0001] This utility model belongs to the field of quilting machine manufacturing technology, and specifically relates to a safety protection device. Background Technology

[0002] The safety protection devices of quilting machines usually only provide safety protection in terms of control, such as using a safety light curtain, which will trigger the machine to stop when a specific area is touched. Such protection level is low, and it is difficult to avoid the danger of objects flying out of the machine during operation, which can easily cause injury to people. This utility model is designed to address this issue. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a safety protection device. In addition to normal mechanical safety protection, the device also realizes linkage with electrical control, which better protects the safety of the operator.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A safety protection device includes a main body of a safety protection cover consisting of a rotating shaft, an acrylic glass plate, and connecting parts, and a control part of the protection cover consisting of a limit block and a micro switch.

[0006] The acrylic glass plate is fixedly mounted on the rotating shaft;

[0007] The rotating shaft is fixedly mounted on the connector;

[0008] The limiting block is installed on the rotating shaft;

[0009] The connector is used to fix the rotating shaft and the acrylic glass plate;

[0010] When the machine is operating normally, a person can observe its operation through the acrylic glass plate. When manual operation is required, the acrylic glass plate is flipped, causing the rotating shaft to rotate. The limit block rotates along with the shaft. The limit block has a groove. Under normal conditions, the trigger point of the micro switch is located in the groove of the limit block. When the limit block rotates, i.e., when the acrylic glass plate is flipped, the micro switch is triggered, sending a stop signal to the control system. Conversely, when the safety cover is closed, the electronic control system does not receive a signal from the safety cover and can be started.

[0011] Compared with the prior art, the advantages and beneficial effects of this utility model are:

[0012] This invention overcomes the problem that general safety protection devices can only achieve normal mechanical safety protection. Through the design of this invention, it can achieve linkage with the electrical control to stop the machine. When the safety guard is open, it ensures that the machine stops working, thus better protecting the operator's safety. At the same time, in order to facilitate the observation of the machine's operation, the protective plate is made of transparent acrylic sheet. Attached Figure Description

[0015] 1. Rotating shaft 2. Acrylic glass plate 3. Connecting parts 4. Limiting block 5. Micro switch. Detailed Implementation

[0016] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings. It should be noted that these embodiments are descriptive, not limiting, and should not be construed as limiting the scope of protection of this invention.

[0017] A safety protection device includes a main body of a safety protection cover consisting of a rotating shaft 1, an acrylic glass plate 2, and a connecting piece 3, and a control part of the protection cover consisting of a limit block 4 and a micro switch 5.

[0018] The acrylic glass plate 2 is fixedly mounted on the rotating shaft 1;

[0019] The rotating shaft 1 is fixedly mounted on the connector 3;

[0020] The limiting block 4 is installed on the rotating shaft 1;

[0021] The connector 3 is used to fix the rotating shaft 1 and the acrylic glass plate 2;

[0022] When the machine is operating normally, a person can observe the machine's operating status through the acrylic glass plate 2. When the machine requires manual operation, the acrylic glass plate 2 is flipped, which drives the rotating shaft 1. The limit block 4 will rotate together with the rotating shaft 1. The limit block 4 has a groove. Under normal conditions, the trigger point of the micro switch 5 is located in the groove of the limit block. When the limit block 4 rotates, that is, when the acrylic glass plate 2 is flipped, the micro switch 5 will be triggered, sending a stop signal to the control system. Conversely, when the safety guard is closed, the electronic control system does not receive a signal from the safety guard and can be operated to start.
