[0031] Further, the material roller 301 is connected with the support frame 3, the winding roller 302 comprises a driving motor, the cutter 7 comprises a lifting device, the lifting device is an electric lifting structure, and the lifting device is used for lifting the inner blade, the transverse length of the cutter 7 is the same as the length of the mounting block, the blades 501 are arranged in a spaced manner, the blades 501 are arranged in a pair of rhombic blade structures, and the total length of the fixing block 5 is less than the length of the winding roller 302.

[0032] The inner side of the fixing groove 404 is provided with a baffle 9, the bottom end of the baffle 9 is provided with buckle blocks 901 on both sides, the baffle 9 is arranged in an inverted U-shaped structure, the fixing groove 404 and the buckle blocks 901 are buckle-fixedly connected, the placing groove 402 is arranged in an inclined manner, and the inner side of the bottom end is provided with an arc-shaped groove; the blades are arranged in a zigzag manner, and the concave teeth and the blades 501 are vertically correspondingly arranged in an up-down mode.

[0033] The bottom end of the heat transfer plate 6 is provided with a resistance type heating module, the lifting plate 604 and the telescopic groove 602 are elastically connected through the telescopic spring 603, and the clamping blocks are fixed at both ends of the heat transfer plate 6.

[0034] The planar plate 4 is mounted at the bottom side of the film roller 8, and the planar plate 4 and the bottom end of the device main body 1 are fixedly connected, the hot stamping roller 801 is detachably connected, and the cutter 7 and the fixing groove 404 are vertically correspondingly arranged in an up-down mode.

[0035] The device main body 1 further comprises a hot stamping spraying device, a micro-control chip module, a power module and a wire arrangement circuit, the fixing frame 2 is mounted in the interior of the device main body 1 and is fixedly mounted.

[0036] A label printing production process for safety helmets is provided, and the specific steps are as follows:

[0037] Step one. Spraying on the surface of the PVC paper through the hot stamping spraying device, the coating amount is 1.5-2 g / m 2 , the layer thickness is 0.05 mm-0.1 mm, the ink comprises 1-2 parts of polyurethane resin oil and 0.5-1 part of gum calcium, the back of the PVC paper comprises EVA hot melt adhesive, and the EVA hot melt adhesive comprises water-based polyurethane adhesive;

[0038] Step two. The safety helmet is inserted into the bottom end of the clamping piece 601 at both ends of the heat transfer plate 6, clamped through the telescopic spring 603 and the lifting plate 604, and based on the heat transfer plate 6 at the bottom side, the brim and the inner cavity of the safety helmet are heated; at this time, the worker applies the oil removing agent heated to 50 degrees to the surface of the safety helmet to complete the work preparation process.

[0039] Step three. The sprayed PVC paper is wound by the winding roller 302, cut by the blade knife 501 on the plane plate 4 along the sprayed PVC paper pattern, leaving a traction vertical bar between the blade knives 501, continuously driving the PVC paper to the rear, avoiding the traction vertical bar at the concave tooth of the blade knife 7 when the blade knife 7 is downward from the fixed groove 404, only cutting the label pattern and falling into the placement groove 402, and the PVC paper side edge material and the traction vertical bar are penetrated from the arc-shaped groove of the placement groove 402 and wound by the winding roller 302;

[0040] Step four. Because the label contains materials after thermal printing, the label can be directly attached on the safety helmet with the oil removal agent, realizing firm and not falling off.

[0041] Specifically, the device body 1 is provided with an opening and closing cover 101 and a handle 102 on the overall surface, so as to protect the inside thermal printing spraying device, micro control chip module, power module and wire arrangement circuit. When maintenance is needed, the inside structure can be exposed by directly opening the opening and closing cover 101 through the handle 102. The fixed frame 2 is arranged in the middle side of the inside of the device body 1. The front turning roller 201 is used to complete the middle turning function in cooperation with the winding roller 302. The PVC paper wound on the material roller 301 will complete the thermal printing spraying function in cooperation with the thermal printing spraying device in the middle side of the inside, and the winding function of the rear end will be completed by the winding roller 302 and the driving motor thereof. The film covering roller 8 and the thermal printing roller 801 arranged on the rear side of the fixed frame 2 are mainly used for the surface extrusion film forming function after thermal printing.

[0042] Because the plane plate 4 structure is designed on the rear side of the device body 1, the support frame 3 at the bottom of the plane plate 4 supports, and the plane plate 4 and the rear bottom end of the device body 1 are connected to form the front and rear fixed function. The blade knife 501 is arranged on the surface of the plane plate 4 from near to far, which is used for the cutting groove 401, the placement groove 402 and the fixed groove 404 structure used in cooperation with the blade knife 7. Because the blade knife 501 is arranged in pairs, the inside of the blade knife 501 will leave the traction vertical bar after cutting the PVC paper. Because the width of the blade knife 501 is smaller than the PVC paper, a small amount of edge allowance will be left on both sides of the PVC paper, and the limit is formed on the inside of the clamping strip 403. Therefore, the middle traction vertical bar extends from the lower side of the inverted U-shaped baffle 9 and is wound from the arc-shaped groove on the inside of the placement groove 402 to the winding roller 302. The edge allowance on both sides directly penetrates the arc-shaped structure of the plane plate 4 from the outside of the heat transfer plate 6 to the winding roller 302.

[0043] The label after being cut by the blade knife 501 still has a strip structure, so the label pattern is located at the bottom end of the baffle 9 at the cutting groove 401. The blade knife 7 is downward cut until the blade enters the cutting groove 401. Then the label will fall into the placement groove 402 according to the inclined angle of the plane plate 4. Because the gap of the arc-shaped groove is small, the PVC paper will be placed on the inside of the placement groove 402, so as to be directly used by the staff subsequently.

[0044] During operation, the worker simply uses the telescopic groove 602 on the bottom side of the clamping member 601 to extend the spring 603 and lift plate 604 from the side of the heat transfer plate 6 to clamp the brim of the helmet. Since the heat transfer plate 6 is in a heated state for a long time, the brim is directly subjected to clamping contact heating, and the middle part is heated by upward hot air, so that the inner top of the helmet is heated and the brim is heated. Where the safety helmet needs to be labeled, the worker or robotic arm directly applies a degreasing agent with a certain temperature to accelerate the heat exchange between the front and back of the label.

[0045] The raw materials used in the label, including polyurethane resin oil, calcium colloid, and water-based polyurethane adhesive, all have a certain temperature absorption function. When the amount of gelling agent added is reduced, a large amount of the temperature during the heat printing process can be retained, so that the label is at a relatively high temperature inside and outside when it is applied to the safety helmet. The bonding effect produced by the water-based polyurethane adhesive under the condition of high temperature front and back makes the edge of the label more firmly bonded. At the same time, when the PVC label is applied at high temperature, the addition of calcium colloid to the ink and the relatively thin coating can reduce the mutual staining of inks after heating. When it is applied to the surface of the safety helmet, the heating effect can further increase the brightness of the ink itself.

[0046] The overall structure of the device is simple. The process of cutting and attaching the label to the safety helmet can be completed using only the rear cutting structure. Compared with the prior art, the edge curling rate of the labeling process and the structure used in this invention is reduced by 10% under the same time and environmental conditions. In particular, the main body 1 of the device can be made so that if the cutting structure for the label is not required, the rear structure can be disassembled, the thermal printing roller 801 can be disassembled and installed on the front side, the material roller 301 can be equipped with a winding motor, and the steering roller 201 can be replaced with a film coating roller 801. At this time, the overall structure becomes a simple label printer, which can achieve the desired effect for labeling processes in different environments, with different needs and under different conditions.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
