[0026] Please refer to Figures 1 to 4 The embodiment of the utility model provides a high-density polyethylene non-woven fabric branding device for desiccant, comprising a support platform 1 erected on the ground and in a trapezoidal shape as a whole, a conveying mechanism 2 arranged on the support platform 1, and a branding heating mechanism 3 arranged in the middle of the support platform 1, wherein the branding heating mechanism 3 comprises a heating support frame 31 erected on the support platform 1, a hydraulic cylinder 32 arranged on the heating support frame 31 and whose output shaft extends downward through the heating support frame 31, a buffer component 33 arranged on the output shaft of the hydraulic cylinder 32, a hot pressing plate 34 arranged on the buffer component 33, and a supporting bottom film 35 arranged on the support platform 1 and located just below the hot pressing plate 34; the hot pressing plate 34 is provided with text or symbols, and whether it is text or symbol or both can be set according to actual needs, so no specific limitation is made in this embodiment.

[0027] like Figures 1 to 4 As shown, when it is necessary to print the high-density polyethylene nonwoven fabric, the conveying mechanism 2 conveys the high-density polyethylene nonwoven fabric to the top of the supporting bottom film 35 of the imprint heating mechanism 3, the hot pressing plate 34 is heated, and the hydraulic cylinder 32 starts to drive the buffer assembly 33 connected to its output shaft and the hot pressing plate 34 connected to the buffer assembly 33 to press down, so that the text or symbol on the hot pressing plate 34 is hot pressed onto the high-density polyethylene nonwoven fabric to form an imprint, and then the conveying mechanism 2 continues to push the high-density polyethylene nonwoven fabric to carry out the next hot pressing. The overall automation level is high, the conveying mechanism 2 automatically conveys, and the conveying is stable. Compared with printing with ordinary ink, there is no need to wait for the ink to dry, and its speed is faster and more efficient. With the conveying speed of the conveying mechanism 2, the effect of hot pressing once per second can be achieved.

[0028] like Figures 1 to 3As shown, by arranging a buffer assembly 33 between the hot press plate 34 and the hydraulic cylinder 32, when the hydraulic cylinder 32 is started, the buffer assembly 33 moves downward synchronously, and provides a buffering reaction force to the downward impact when the hot press plate 34 contacts the high-density polyethylene non-woven fabric, so that the hot press plate 34 will not over-imprint the high-density polyethylene non-woven fabric and damage other structures due to excessive impact when pressing downward. When the output shaft of the hydraulic cylinder 32 retracts, it also provides a buffering reaction force for the upward driving force of the hot press plate 34, preventing the hot press plate 34 from moving upward excessively and causing damage to other structures, which is beneficial to the coordination between the various components and has higher safety.

[0029] like Figure 2 and Figure 4 As shown, by arranging a supporting bottom film 35 on the support platform 1 directly opposite to the bottom of the hot pressing plate 34, the high-density polyethylene non-woven fabric is effectively supported, and the hot pressing plate 34 is prevented from damaging other structures when hot pressing the high-density polyethylene non-woven fabric, thereby having higher safety.

[0030] Preferably, the pressure of the hydraulic cylinder 32 is 0.6 kg.

[0031] Preferably, the hot pressing temperature of the hot pressing plate 34 is 120 degrees Celsius.

[0032] Preferably, the high-density polyethylene nonwoven fabric is a high-density polyethylene nonwoven fabric with a width of 500 mm and a diameter of 600 mm.

[0033] Regarding the specific structural setting of the buffer component 33, as shown in FIG. Figures 1 to 3 As shown, the buffer assembly 33 includes a buffer plate 331 arranged on the output shaft of the hydraulic cylinder 32, at least one buffer column 332 respectively arranged between the buffer plate 331 and the hot pressing plate 34, and at least one buffer spring 333 correspondingly sleeved on the buffer column 332. The upper end of the buffer spring 333 presses on the buffer plate 331 and the other end presses on the hot pressing plate 34. When the hot pressing plate 34 is driven by the hydraulic cylinder 32 to move downward, the hot pressing plate 34 contacts the high-density polyethylene non-woven fabric and presses it on the supporting bottom film 35. The buffer spring 333 is subjected to the impact force fed back by the hot pressing plate 34, and gives the hot pressing plate 34 a buffering reverse force under the action of its own elastic restoring force, thereby buffering the downward impact of the hot pressing plate 34, so that the hot pressing plate 34 will not over-imprint the high-density polyethylene non-woven fabric and damage other structures due to excessive impact when pressing downward, and has high safety.

[0034] Preferably, Figure 1 to Figure 2As shown, there are 4 groups of buffer columns 332, which are respectively located at the four corners of the buffer plate 331 and the four corners corresponding to the hot press plate 34; there are also 4 groups of buffer springs 333, which are respectively set on the 4 groups of buffer columns 332. The number of the buffer columns 332 and the buffer springs 333 is corresponding to the number of groups and are respectively set at the four corners of the buffer plate 331 and the four corners corresponding to the hot press plate 34, so that the buffer springs 333 have a uniform buffering force on the four corners of the hot press plate 34, which has a higher safety.

[0035] Regarding the specific structural setting of the heating support frame 31, Figure 1 to Figure 2 As shown, the heating support frame 31 includes four groups of heating support columns 311 respectively mounted on the support platform 1, and a heating support plate 312 fixed between the heating support columns 311. The hydraulic cylinder 32 is fixed on the heating support plate 312 and its output shaft extends downward through the heating support plate 312. The four groups of heating support columns 311 are respectively mounted on the four corners in the middle of the support platform 1, so as to achieve uniform support force and prevent collapse and displacement. The heating support plate 312 is used to fix and support the hydraulic cylinder 32 to prevent the hydraulic cylinder 32 from shifting during operation, resulting in inaccurate hot pressing imprinting, thereby ensuring the imprinting accuracy of the device.

[0036] In order to further improve the printing accuracy of this equipment, such as Figure 1 to Figure 2 As shown, the device also includes at least one heating limit assembly 36 disposed between the heating support frame 31 and the support platform 1, the heating limit assembly 36 includes a heating limit column 361 disposed at the upper end fixed on the heating support plate 312 and the lower end fixed to the middle of the support platform 1, and a limit buffer seat 362 fixed on the side of the buffer plate 331 and sliding on the heating limit column 361, and the heating limit column 361 penetrates the buffer plate 331. When the hydraulic cylinder 32 drives the buffer plate 331 to move up and down, the buffer plate 331 drives the limit buffer seat 362 to slide on the heating limit column 361, so that the buffer plate 331 is guided by the heating limit column 361 and is limited in stroke to make vertical radial movement, thereby realizing the stroke limitation of the buffer plate 331 and the hot press plate 34 disposed on the buffer plate 331, and improving the accuracy of the hot press plate 34 in printing high-density polyethylene non-woven fabrics.

[0037] Preferably, Figure 1 to Figure 2As shown, the number of the heating limit assemblies 36 is 2 groups, which are symmetrically arranged on both sides of the buffer plate 331, so that both sides of the buffer plate 331 are subjected to uniform limiting and guiding forces, thereby further improving the accuracy of the hot pressing plate 34 in printing high-density polyethylene non-woven fabric.

[0038] Regarding the installation method of the supporting bottom film 35, Figure 1 to Figure 2 As shown, a mounting groove for mounting the supporting bottom film 35 is provided in the middle of the support platform 1 , and the supporting bottom film 35 is mounted on the mounting groove accordingly.

[0039] In order to prevent the support platform 1 from being damaged when the hot pressing plate 34 moves down for printing, Figure 1 to Figure 2 As shown, the height of the support base film 35 is higher than the height of the mounting groove. After the hot pressing plate 34 moves downward, the high-density polyethylene non-woven fabric is pressed against the support base film 35 for hot pressing to form an imprint. Since the height of the support base film 35 is higher than the height of the mounting groove, the hot pressing plate 34 is at a certain height away from the bracket platform 1 during hot pressing, thereby effectively preventing the hot pressing plate 34 from damaging the bracket platform 1 when moving downward for printing, thereby improving the safety of the device.

[0051] Step (3), the hydraulic cylinder 32 is started, and the buffer assembly 33 and the preheated hot pressing plate 34 are pressed downward with a pressure of 0.6 kg, so that the hot pressing plate 34 heat-presses the text or symbol set at the bottom onto the high-density polyethylene non-woven fabric, and forms a corresponding imprint of the text or symbol on the surface of the high-density polyethylene non-woven fabric. Compared with printing with ordinary ink, there is no need to wait for the ink to dry, and the speed is faster and the efficiency is higher;
