Description

Technical Field

[0001] This utility model relates to a drying device for paper product production, belonging to the field of paper product processing technology. Background Technology

[0002] Paper products are various products made primarily from paper through processing. They are widely used in daily life, office work, packaging, art, and many other fields. Common paper products include paper, tissues, paper bags, cardboard boxes, cardboard, and toilet paper. Paper products not only have good recyclability but also meet various functional requirements, such as absorbency, breathability, strength, and flexibility.

[0003] Authorization announcement number (CN 212720751 U) discloses a drying device for paper product production, including a drying box. A heating mechanism is fixedly connected to the inner wall of the drying box. Two symmetrically distributed rectangular through holes are opened on both outer walls of the drying box. A U-shaped tube is fixedly connected to the upper and lower surfaces of the drying box. An air pump is fixedly connected to the upper surface of the drying box. The air inlet of the air pump is fixedly connected to the wall of the U-shaped tube, and the output end of the air pump is fixedly connected to a connecting pipe. This utility model enables the paper product drying device to have a waste heat recovery function, improves the heat utilization rate, and thus improves the energy-saving performance of the paper product drying device. It can also avoid the pollution of the surrounding environment by the dispersion of fine particles and improve the environmental protection performance of the paper product drying device. At the same time, the drying device can dry two parts of paper products simultaneously, improving the efficiency of paper product production and drying.

[0004] However, existing drying equipment lacks shaping measures during use, which may cause wrinkles on the surface of paper products during the drying process. These wrinkles not only affect the appearance of paper products, making their surfaces uneven and rough, but may also lead to a decline in the quality of paper products, resulting in uneven thickness or strength, affecting subsequent processing and use.

[0005] Therefore, a drying device for paper product production is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1-8 As shown, this utility model embodiment provides a drying device for paper product production, including:

[0035] The drying assembly 100 includes a housing 101, a heating chamber 102, an assembly plate 103, a fan 104, a filter screen 105, and an electric heating tube 106. The heating chamber 102 is fixedly installed on the rear side of the housing 101. The assembly plate 103 is fixedly connected to the top of the heating chamber 102 by bolts. The fan 104 is fixedly connected to the surface of the assembly plate 103. The filter screen 105 is fixedly connected to the inside of the heating chamber 102. The electric heating tube 106 is fixedly connected to the inside of the heating chamber 102. A ventilation pipe 107 is connected to the bottom of the heating chamber 102. A ventilation hood 108 is fixedly installed on the inside of the housing 101. The ventilation hood 108 is connected to the ventilation pipe 107.

[0036] The positioning component 200 includes a transmission plate 202 movably connected to the inside of the housing 101. Positioning rods 203 are fixedly installed on both the front and rear sides of the inner side of the transmission plate 202. Drying boxes 204 are fixedly installed on the inner side of the positioning rods 203. There are three drying boxes 204, which are equidistantly distributed along the inner side of the two positioning rods 203. A cover plate 205 is provided on the top of the three drying boxes 204. Positioning blocks 207 are fixedly installed on the inner side of the three cover plates 205, and the inner side of the positioning blocks 207 is hollow.

[0037] A handle 206 is fixedly installed on the top of the three positioning blocks 207. A connecting rod 208 is fixedly installed on the bottom perimeter of the three cover plates 205. A connecting plate 209 is fixedly installed on the lower end of the connecting rod 208. A through groove 211 is opened on the inner perimeter of the three positioning blocks 207. A through hole 212 is opened on the top perimeter of the three positioning blocks 207. The through hole 212 is connected to the through groove 211. The connecting rod 208 and the connecting plate 209 extend through the through hole 212 to the inner side of the through groove 211. A rigid spring 210 is fixedly installed on the top of the connecting plate 209. The rigid spring 210 is located on the outer side of the connecting plate 209. The upper end of the rigid spring 210 is fixedly connected to the inner side of the through groove 211.

[0038] By setting the positioning component 200, the rigid spring 210 can provide tension, causing the connecting plate 209, connecting rod 208 and cover plate 205 to move downward, so that the positioning block 207 fits against the paper product and performs shaping treatment, ensuring that the paper surface is flat and smooth, avoiding wrinkles or uneven textures on the surface of the paper product, thereby improving the appearance quality of the paper product, enhancing the strength and stability of the paper product, reducing deformation or cracking in subsequent processing, and ensuring the performance of the product.

[0039] Example 2

[0040] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, in one embodiment, a servo motor 201 is fixedly installed on the left side of the housing 101. The output end of the servo motor 201 is fixedly connected to the transmission plate 202. The electric heating tube 106 is integrally formed from conductive ceramic material. The electric heating tube 106 has a current path inside. After being energized, it heats up through the resistance of the material itself. A filter screen 105 is bolted to the inside of the heating box 102. The filter screen 105 is detachable. The bolts can be removed to clean and maintain the filter screen 105 when needed. Support seats 214 are fixedly installed on the left and right sides of the bottom of the inner cavity of the housing 101. Auxiliary wheels 213 are movably connected to the front and rear sides of the top of the support seat 214. The transmission plate 202 is in contact with the auxiliary wheels 213.

[0041] The servo motor 201 drives the transmission plate 202 at the output end to rotate, causing the drying chamber 204 and the cover plate 205 to rotate, thereby ensuring uniform drying of paper products. The filter screen 105 can play a dust prevention role and filter the air conveyed by the assembly plate 103. The auxiliary wheel 213 and the support seat 214 provide support, improving the stability of the transmission plate 202 when rotating.

[0042] In operation, this invention works as follows: by gripping the handle 206 and pulling the cover plate 205 upwards, the positioning block 207 moves upwards. After placing the paper product inside the drying chamber 204, the handle 206 can be released. At this time, the rigid spring 210, having lost external pressure, rebounds due to its own tension, thereby causing the connecting plate 209 and connecting rod 208 to move downwards. During the movement of the connecting rod 208, the cover plate 205 and positioning block 207 move downwards, contacting the paper product and compressing it. At this time, the fan 104 is activated, causing the air to move downwards. After the air passes through the filter screen 105 and contacts the electric heating tube 106, it undergoes heating treatment. The heated air is guided by the ventilation pipe 107 and conveyed upwards through the ventilation hood 108, contacting the paper product. At this time, the servo motor 201 drives the transmission plate 202 at the output end to rotate, causing the drying chamber 204 and the cover plate 205 to rotate, ensuring that the paper product is dried evenly.
