Description

Technical Field

[0001] The utility model relates to the technical field of thermal paper gluing, in particular to a thermal paper gluing and cooling device. Background Technique

[0002] Under the background of green printing, the bottomless paper label has attracted much attention because it saves the bottom paper, not only saving the paper cost, but also making more labels per roll of material, thus reducing the transportation quantity and the cost of enterprises, and meeting the green environmental protection requirements of enterprises and society. The thermal paper label is one of the most widely used label papers. The bottomless paper thermal label is a self-adhesive thermal paper label without a bottom paper. Generally, graphics and texts are printed on the thermal paper first, then silicone oil is coated on a coating machine to prevent the self-adhesive labels from sticking to each other, and finally hot melt adhesive is coated on a hot melt adhesive coating machine and then curled into a roll. However, due to the characteristic that the thermal paper starts to show color when heated above 70°C, when directly coating the hot melt adhesive at about 200°C on the back of the thermal paper, the too high temperature will cause the thermal paper to show color and be scrapped.

[0003] Regarding the thermal paper gluing and cooling device, through retrieval, it is found that the publication number CN219965473U discloses a thermal paper gluing and cooling device and a thermal paper gluing device. In this cooling device, on the upper surface of the thermal paper, the hot glue being coated is directly blown by air flow to accelerate the heat dissipation of the hot melt adhesive. The main exhaust hood is used to extract the dissipated hot air to ensure that the heat in the main exhaust hood will not accumulate and cause the temperature to rise. The bottom cooling water tank ensures that the water tank is at a relatively low temperature through an external water flow cycle. Through the cooling plate made of copper with good thermal conductivity, it is ensured that the bottom surface of the thermal paper in close contact with the cooling plate maintains a constant temperature. However, during the use of the exhaust hood in this cooling device, there will inevitably be some glue on the surface of the cooling plate from the hot melt adhesive on the thermal paper, which will affect the tension of the thermal paper and have an impact on the gluing of the thermal paper. Moreover, there is no separation structure between the exhaust hood and the base, making it inconvenient for the staff to remove the hot melt adhesive on the cooling plate.

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0021] The embodiments of the present application provide a thermal paper glue application and cooling device. Through the support rod and the connecting groove provided by the connecting component, the air extraction hood and the base can be connected together, and the air extraction hood and the base can also be separated, so that it is convenient for the staff to remove the hot melt glue. Secondly, through the dust-proof net and the slide groove provided by the dust-proof component, it can prevent the dust from being blown onto the surface of the thermal paper when the hair dryer is working, avoiding the influence of dust on the surface of the thermal paper on the glue application effect, and reducing the qualification rate of the thermal paper.

[0022] The following details the thermal paper glue application and cooling device. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0023] The following describes the present application in detail in conjunction with the accompanying drawings and specific embodiments. Please refer to Figures 1 - 5In this embodiment, a thermal paper gluing and cooling device is provided, including: a base 1, an air extraction hood 101 is arranged on the top of the base 1, a gluing head 102 is arranged on one side of the base 1, an air extraction fan 2 is arranged on the top of the base 1, a connecting component is arranged between the base 1 and the air extraction hood 101 for connecting the base 1 and the air extraction hood 101 together, and a dust-proof component is arranged inside the air extraction hood 101 for preventing dust from falling onto the thermal paper. Embodiment

[0024] The connecting component includes: two connecting plates 3 connected to the two side surfaces at the bottom of the base 1, a support rod 301 connected to the tops of the two connecting plates 3, a connecting groove 302 opened at the bottom of the air extraction hood 101 and matching with the support rod 301, a clamping groove 303 opened inside the connecting groove 302, an ejection groove 304 opened on one side surface of the support rod 301 corresponding to the position of the clamping groove 303, an ejection spring 305 connected inside the ejection groove 304, and one end of the ejection spring 305 is connected with a clamping block 306 matching with the clamping groove 303.

[0025] When the cooling roller 104 needs to be cleaned, the clamping block 306 can be pressed. When the clamping block 306 is pressed, it will move into the ejection groove 304. When the clamping block 306 moves, it will squeeze the ejection spring 305. When the ejection spring 305 is squeezed, it will become compressed, so that the clamping block 306 can enter the ejection groove 304. After the clamping block 306 enters the ejection groove 304, the fixation of the support rod 301 is released, so that the air extraction hood 101 and the base 1 can be separated. After cleaning the cooling roller 104, align the connecting groove 302 with the support rod 301. After alignment, place the air extraction hood 101 so that the support rod 301 enters the connecting groove 302. During the process of the support rod 301 entering the connecting groove 302, the clamping block 306 will be pushed into the ejection groove 304 by the inner wall of the connecting groove 302. When the support rod 301 completely enters the connecting groove 302, the ejection groove 304 will correspond to the position of the clamping groove 303. At this time, the ejection spring 305 will start to return to its original state. During the process of the ejection spring 305 returning to its original state, it will push the clamping block 306 back to its original position, so that the clamping block 306 enters the clamping groove 303 to connect the base 1 and the air extraction hood 101 together. Embodiment

[0026] On the basis of Embodiment 1, the dust-proof component includes: a fixing groove 201 opened at the bottom of the air extraction hood 101, a mounting block 202 arranged inside the fixing groove 201, a mounting hole 203 opened at the top of the mounting block 202, a dust-proof net 204 arranged at the bottom of the mounting block 202, a bracket 205 arranged inside the mounting hole 203, a motor 206 mounted on the top of the bracket 205, a rotating block 207 connected to the bottom of the motor 206 through a driving rod, a fan blade 208 connected to the surface of the rotating block 207, two stoppers 209 connected to the bottom of the mounting block 202, and a sliding groove 2010 matched with the dust-proof net 204 opened on one side of the two stoppers 209 close to each other.

[0027] Start the motor 206 through the control switch. After the motor 206 starts, it will drive the rotating block 207 to rotate. After the rotating block 207 rotates, it will drive the fan blade 208 to rotate, so as to blow air on the thermal paper, thereby drying the glue on the thermal paper. The dust-proof net 204 can prevent the fan blade 208 from blowing dust onto the surface of the thermal paper when working. When the dust-proof net 204 needs to be cleaned, hold the dust-proof net 204, and after holding it, pull the dust-proof net 204 outwards, so that the dust-proof net 204 leaves the position of the mounting hole 203 through the sliding connection with the sliding groove 2010, thereby cleaning the dust-proof net 204. Embodiment

[0028] On the basis of Embodiment 1, an installation groove 103 is opened at the top of the base 1, two cooling rollers 104 are installed inside the installation groove 103, a plurality of transmission rollers 105 are arranged between the two cooling rollers 104, an air extraction duct 106 is opened at the bottom of the air extraction hood 101, a control switch is arranged on one side of the base 1, the motor 206 and the air extractor 2 are powered by an external power supply, the control switch is electrically connected to the motor 206 and the air extractor 2, and the control switch can control the start of the motor 206 and the air extractor 2.

[0029] The cooling roller 104 can contact the back of the thermal paper and cool it, so that during the process of air-cooling the thermal paper, the cooling roller 104 can be used to dissipate heat from the thermal paper at the same time. The air extractor 2 will extract the air at the bottom of the air extraction hood 101 through the air extraction duct 106, accelerating the air flow in the air extraction hood 101 and preventing the temperature in the air extraction hood 101 from being too high.

[0030] The specific working process is as follows:

[0031] Start the motor 206 by controlling the switch. After the motor 206 starts, it will drive the rotating block 207 to rotate. After the rotating block 207 rotates, it will drive the fan blade 208 to rotate, so as to blow air on the thermal paper, thereby drying the glue on the thermal paper. The dust-proof net 204 can prevent the fan blade 208 from blowing dust onto the surface of the thermal paper when working. When it is necessary to clean the dust-proof net 204, grasp the dust-proof net 204, and after grasping, pull the dust-proof net 204 outwards, so that the dust-proof net 204 leaves the position of the mounting hole 203 through the sliding connection with the sliding groove 2010, thereby enabling the cleaning of the dust-proof net 204;

[0032] The cooling roller 104 can contact the back of the thermal paper and cool it, so that during the process of air-cooling the thermal paper, the cooling roller 104 can be used to dissipate heat from the thermal paper at the same time. The exhaust fan 2 will extract the air at the bottom of the exhaust hood 101 through the exhaust duct 106, accelerating the air flow in the exhaust hood 101 and preventing the temperature in the exhaust hood 101 from being too high;

[0033] When it is necessary to clean the cooling roller 104, the latch 306 can be pressed. When the latch 306 is pressed, it will move towards the inside of the ejection groove 304. When the latch 306 moves, it will squeeze the ejection spring 305. When the ejection spring 305 is squeezed, it will become compressed, enabling the latch 306 to enter the inside of the ejection groove 304. After the latch 306 enters the inside of the ejection groove 304, the fixation of the support rod 301 is released, so that the exhaust hood 101 and the base 1 can be separated. After cleaning the cooling roller 104, align the connection groove 302 with the support rod 301. After alignment, place the exhaust hood 101 so that the support rod 301 enters the inside of the connection groove 302. During the process of the support rod 301 entering the inside of the connection groove 302, the latch 306 will be pushed into the inside of the ejection groove 304 by the inner wall of the connection groove 302. When the support rod 301 completely enters the inside of the connection groove 302, the ejection groove 304 will correspond to the position of the card slot 303. At this time, the ejection spring 305 will start to return to its original state. During the process of the ejection spring 305 returning to its original state, it will push the latch 306 back to its original position, enabling the latch 306 to enter the inside of the card slot 303, thereby connecting the base 1 and the exhaust hood 101 together.
