[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4A protective clothing compressing machine with power-off protection comprises a frame 1, a compressing platform 1 arranged on the frame 1, a pressing plate assembly 3 and a machine head 4 are arranged on the frame 1 above the compressing platform 1, a lifting cylinder 5 for driving the pressing plate assembly 3 to rise and fall is arranged on the machine head 4, the pressing plate assembly 3 comprises a pressing plate mounting frame 31 and a compressing plate 32 mounted on the pressing plate mounting frame 31, the lifting cylinder 5 is vertically arranged and is provided with a telescopic vertical rod 51 vertically penetrating the cylinder body thereof, the bottom end of the telescopic vertical rod 51 passes through the machine head 4 and is connected to the pressing plate mounting frame 3 1 is fixedly connected, the top of the telescopic vertical rod 51 is fixedly connected with a limiting column 52 with a larger diameter ratio, and the top of the cylinder body of the lifting cylinder 5 is provided with a power-off brake mechanism 6, which includes a fixing plate 61 fixedly installed on the top of the cylinder body of the lifting cylinder 5 and a brake cylinder 62 fixed on the fixing plate 61. A push block 63 is fixedly connected to the telescopic stem of the brake cylinder 62, and a support sheet 64 bent into an inverted "L" shape is connected to the front end of the push block 63. A spring 65 is provided between the push block 63 and the cylinder body of the brake cylinder 62. Specifically, when the booster is operating normally, the brake cylinder 62 pulls the push block 63 back, and the spring 65 is in a compressed state. When the power is off, the push block 63 loses the pulling force of the brake cylinder 62 and quickly pops out under the action of the spring 65, so that the support sheet 64 clamps the limiting column 52. The utility model adopts a power-off brake mechanism 6. In the event of a sudden power outage, the support sheet 64 pops out under the action of the spring 65 to support the limit column 52, and pulls the pressure plate assembly 3 through the telescopic vertical rod 51 to prevent the pressure plate assembly 3 from suddenly falling and hitting the operator or damaging the product, thereby protecting the personal safety of the workers and reducing errors caused by emergencies.

[0020] Furthermore, a C-shaped notch matching the diameter of the telescopic vertical rod 51 is provided on the support sheet 64. The support sheet 64 leans against the telescopic vertical rod 51 through the C-shaped notch, which is beneficial to increase its contact area with the support column and improve the reliability and effectiveness of the power-off brake mechanism 6.

[0021] Furthermore, a cylinder support 7 is fixedly installed on the pressing plate mounting frame 31. A plate-changing cylinder 71 with its cylinder body hinged thereto is provided on the cylinder support 7. A rotating shaft 321 is installed at the bottom of the pressing plate mounting frame 31. A plate-changing support 322 is fixedly installed on the rotating shaft 321. The compensating pressing plate 32 includes a heating pressing plate and a cooling pressing plate respectively arranged at both ends of the plate-changing support 322. A rocker 323 is also fixedly installed on the rotating shaft 321. The end of the telescopic rod of the plate-changing cylinder 71 is hinged to the rocker 323. The present utility model combines two working modes of heating and melting adhesive bonding and cooling and compensating pressure reinforcement. The adhesive can be quickly melted by the heating pressing plate, and then the cooling pressing plate is used for compensating pressure during the cooling process to prevent the bonding part from being separated due to stress before the adhesive cools. The present utility model can conveniently control the rotation of the plate-changing support 322 by driving the rotating shaft 321 with the plate-changing cylinder 71, so as to realize the quick switching between the heating pressing plate and the cooling pressing plate, reduce the time and labor required for replacing the pressing plate, and improve the production efficiency.

[0022] Furthermore, an anti-collision buffer pad 311 corresponding to the plate-changing support 322 is also provided at the bottom of the pressing plate mounting frame 31.

[0023] Furthermore, a linear guide bushing is provided in the machine head 4. A guide rod 8 fixedly connected to the pressing plate mounting frame 31 of the compensating pressing plate 32 passes through the linear guide bushing and is in sliding fit therewith. The sliding fit between the guide rod 8 and the linear guide bushing limits the degree of freedom of the pressing plate mounting frame 31 of the compensating pressing plate 32 in the vertical direction, making it more stable during the lifting process and helping to protect the safety of the equipment and products.

[0024] Furthermore, a pressure strip 324 exceeding the plate surface is provided at the edge of the compensating pressing plate 32. Before the compensating pressing plate 32 contacts the protective clothing, the surrounding fabric is first pressed tightly by the pressure strip 324 to prevent the fabric from running off.

[0025] Furthermore, an elastic sponge pad 9 is laid on the compensating pressing table 1.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
