Description

Technical Field

[0001] The present invention relates to the technical field of paper product drying, in particular to an energy-saving paper product drying system. Background Art

[0002] There are many products in the paper packaging industry, mainly including three categories: corrugated paper, honeycomb paper and embossed paper. The paper packaging derived from these three categories includes cartons, paper boxes, paper bags, paper cans, pulp molding, etc. Among them, cartons, paper boxes and paper cups are the products with larger sales volume in the industry product market. The scope of use of paper packaging is very wide, and the use of various types of paper packaging is spread across all aspects of human life and production. When producing and processing paper products, the paper products need to be dried.

[0003] In the existing paper drying process, wet semi-finished products are typically placed in a large drying oven for heat treatment. Because the drying oven has a large internal space and the heat source is typically fixed to one side or a specific location within the oven, the thermal environments experienced by paper products at different locations within the oven vary significantly during the drying process. Paper products near the heat source are directly exposed to the higher-temperature airflow, allowing moisture to evaporate rapidly. However, paper products located at the far end of the oven or in blind spots experience a significantly slower moisture removal rate due to factors such as a longer heat transfer path, attenuated hot air velocity, and a decreasing temperature gradient. This results in some paper products being over-dried while others still retain moisture, leading to an uneven overall moisture content distribution and, in turn, reduced quality of the finished paper products.

[0004] In view of this, we propose an energy-saving paper drying system. Summary of the Invention

[0005] The object of the present invention is to provide an energy-saving paper drying system to solve the problem raised in the above-mentioned background technology that paper products near the heat source area are directly exposed to the action of high-temperature airflow, and the moisture evaporates quickly, while paper products located at the far end of the box or in the dead corner of the airflow have a significantly slower moisture removal rate due to factors such as the longer heat transfer path, the attenuation of the hot air flow rate and the decrease in the temperature gradient. This causes some paper products to be over-dried while other parts still have residual moisture, resulting in uneven distribution of the overall moisture content, which in turn reduces the quality of the paper products after processing. To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an energy-saving paper drying system, comprising a drying box, wherein the top of the drying box is fixedly connected to a motor, the front side of the drying box is rotatably connected to a heat-insulating cover, the bottom end of the rotating shaft of the motor extends to the interior of the drying box and is rotatably connected to a reciprocating screw rod, the bottom end of the reciprocating screw rod is rotatably connected to the bottom of the inner wall of the drying box, the side of the reciprocating screw rod is movably sleeved with a connecting frame, the front side of the inner wall of the connecting frame is rotatably connected to a connecting rod, support mechanisms for placing paper products are provided on the left and right sides of the front and rear sides of the connecting rod, L-shaped grooves are provided on the left and right sides of the top of the connecting rod, and a deflection mechanism for flipping the connecting rod is slidably provided inside the L-shaped groove, and an extrusion mechanism for stretching the paper products is fixedly provided on the left and right sides of the upper and lower sides of the inner wall of the drying box.

[0006] Preferably, the deflection mechanism includes two L-shaped blocks, and the two L-shaped blocks are respectively slidably connected to the inside of the two L-shaped grooves, and the vertical blocks of the two L-shaped blocks are fixedly connected to a C-shaped frame on opposite sides, and the left and right sides of the connecting rod are movably sleeved with a gear ring, and the left and right sides of the gear ring are provided with an annular groove, and the two vertical plates of the C-shaped frame are fixedly connected to an arc strip on opposite sides, and the side surface of the arc strip slides with the inside of the annular groove, and the lower side of the inner wall of the gear ring is fixedly connected with a moving block, and the bottom of the connecting rod is provided with a connecting groove that matches the moving block. The arc strip can limit the gear ring through the annular groove, so that the gear ring can rotate with the connecting rod as the center and slide on the side of the connecting rod.

[0007] The L-shaped block is fixedly connected to the C-shaped frame and the toothed ring is offset from the L-shaped block and the C-shaped frame when the connecting rod drives the L-shaped block and the long rod upwards, so that the long rod is offset from the L-shaped block and the C-shaped frame and the toothed ring when the connecting rod moves upwards, so that the toothed ring can be staggered with the side of the rack when it moves downwards, thereby preventing the paper product from being repeatedly deflected during drying, thereby ensuring the uniformity of paper drying.

[0008] Preferably, long grooves are provided on the left and right sides of the drying box, and four limit frames are fixedly connected to the inside of the two long grooves. The two limit frames on the upper side are respectively fixedly connected to the front side of the upper side of the inner walls of the two long grooves, and the two limit frames on the lower side are respectively fixedly connected to the rear side of the lower side of the inner walls of the two long grooves. The limit frames are composed of an oblique groove and a straight groove, and the side surfaces of the long rods are respectively slidably matched with the inside of the oblique groove and the straight groove. The rear side of the middle part of the inner walls of the two long grooves is fixedly connected with a rack, which is engaged with a gear ring. When the gear ring rotates to contact the side of the rack, the gear ring can drive the connecting rod to flip 180° through the limitation of the rack.

[0009] Preferably, the support mechanism includes four support plates, two of the four support plates are grouped together and fixedly connected to the left and right sides of the front and rear sides of the connecting rod, two of the first support plates are fixedly connected to the limit plates on the front and rear sides, two of the limit plates are grouped together and rectangular grooves are opened on the left and right sides, four of the rectangular grooves are grouped together and the interior of the rectangular grooves is slidably connected with a square frame, the inner wall of the rectangular groove is fixedly connected with a second compression spring, one end of the second compression spring is fixedly connected to the side of the square frame, and the contact state between the square frame and the support plate is released by moving the two square frames in a group to the upper and lower sides of the inner wall of the rectangular groove, respectively. At this time, the paper product to be dried is placed on the upper side of the support plate, and finally the square frame is released so that one side of the square frame moves to the side of the paper product to be dried, so that the paper product to be dried can be quickly clamped.

[0010] Preferably, the extrusion mechanism includes four connecting blocks, which are respectively fixedly connected to the left and right sides of the upper and lower sides of the drying box, and the four connecting blocks are fixedly connected to a cylinder on each opposite side, the cylinder is rotatably connected to a round rod, the side of the round rod is rotatably connected to a ring, the lower side of the ring is fixedly connected to an L-shaped pressure roller, and the left and right sides of the round rod are sleeved with torsion springs, one end of the torsion spring is fixedly connected to the side of the ring, and the other end of the torsion spring is fixedly connected to the side of the cylinder. When the support plate moves to contact the side of the cross bar of the L-shaped pressure roller and generates pressure, the two L-shaped pressure rollers in a group deflect to the front and rear sides respectively to straighten the top of the paper product, thereby reducing the possibility of deformation due to thermal expansion and contraction when the paper product is dried.

[0011] Preferably, a limiting groove is opened in the middle of the rear side of the drying box, and a T-shaped plate is slidably connected to the inside of the limiting groove. The front side of the vertical plate of the T-shaped plate is fixedly connected to the rear side of the connecting frame. The limiting groove and the T-shaped plate facilitate the horizontal movement of the connecting frame up and down.

[0012] Preferably, a C-shaped handle is fixedly connected to the front side of the insulation cover, and the middle part of the front side of the insulation cover is inlaid with tempered glass. The tempered glass can be explosion-proof, which can facilitate staff to observe the drying of paper products inside the drying box. The C-shaped handle can easily drive the insulation cover to deflect.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the paper products are driven to move up and down by the support plates. When the connecting rod moves down, the two gear rings close inward. When the connecting rod moves up, the two gear rings open outward. When the gear rings close inward, they contact the side surfaces of the rack, causing the two support plates to flip over. When the gear rings open outward, the contact with the side surfaces of the rack is released, so that the two support plates are in a horizontal state, and the L-shaped blocks move into the slots to ensure the horizontal stability of the support plates when moving. When the support plates move, the heat flow in the drying box is dispersed to every corner, ensuring that the paper products are in a uniform state after drying, thereby improving the quality of the paper products after processing.

[0014] In the present invention, the paper product is driven to move up and down by the support plate, so that the support plate and the paper product move to contact the side of the L-shaped pressing roller. The cross bar of the L-shaped pressing roller is subjected to an extrusion force, so that the two L-shaped pressing rollers in a group are deflected to the front and rear sides, twisting the torsion spring. At the same time, the cross bar of the L-shaped pressing roller is translated on the upper side of the paper product, which can quickly straighten the paper product, thereby reducing the deformation and twisting of the paper product due to thermal expansion and contraction, etc., and ensuring the flatness of the paper product after processing.

[0015] In the present invention, two square frames are moved upward and downward inside the rectangular groove, and the second compression spring is compressed to release the square frames from contact with the support plate. At this time, the paper to be dried can be placed on the side of the support plate. Then, the square frames are relaxed and reset by the second compression spring to clamp the paper, thereby ensuring that the paper will not fall when moving in the drying box, thereby ensuring the stability of paper drying.

[0022] Example 3: See also Figures 1 to 12 , this embodiment provides a technical solution: The squeezing mechanism 9 includes four connecting blocks 901, which are respectively fixedly connected to the left and right sides of the upper and lower sides of the drying box 1. The four connecting blocks 901 are fixedly connected to a cylinder 902 on each opposite side.

When the connecting rod 6 moves downward, the two long rods 8010 move to the side of the inner wall of the two lower inclined grooves 103 through the side of the inner wall of the straight groove 104, so that the long rod 8010 drives the L-shaped block 801 and the gear ring 803 to close inward respectively. When the connecting rod 6 moves upward, the two long rods 8010 move to the side of the inner wall of the two upper inclined grooves 103 through the side of the inner wall of the straight groove 104, so that the long rod 8010 drives the L-shaped block 801 and the gear ring 803 to close inward respectively. 03 are opened outwards respectively. When the gear ring 803 is closed inwardly, it contacts the side of the rack 105, thereby causing the two support plates 501 to flip over. When the gear ring 803 is opened outwards, the side contact state with the rack 105 is released, thereby allowing the two support plates 501 to remain in a horizontal state. When the L-shaped block 801 moves, it drives the vertical block of the T-shaped block 806 inside it to move from the inside of one of the slots 808 to the inside of the other slot 808, thereby ensuring the horizontal stability of the support plate 501 when moving. At the same time, when the support plate 501 moves, the heat flow generated inside the drying box 1 is quickly dispersed to various corners inside the drying box 1, ensuring that the paper products are in a uniform state after drying, thereby improving the quality of the paper products after processing. The support plate 501 drives the paper products on its side to move up and down, so that the support plate 501 and the side of the paper products move to contact the side of the L-shaped pressing roller 905. The crossbar of the L-shaped pressing roller 905 is squeezed by the support plate 501, causing the two L-shaped pressing rollers 905 in a group to deflect to the front and rear sides respectively, twisting the torsion spring 906. At the same time, the crossbar of the L-shaped pressing roller 905 moves horizontally on the upper side of the paper products, which can quickly straighten the paper products, thereby reducing the deformation and twisting of the paper products due to thermal expansion and contraction, etc., and ensuring the flatness of the paper products after processing.

[0023] By moving the two square frames 504 in a group toward the upper and lower sides inside the rectangular groove 503 and compressing the second compression spring 505, the square frames 504 are released from contact with the support plate 501. At this time, the paper to be dried can be placed on the side of the support plate 501. Then, the square frames 504 are relaxed and reset by the rebound force of the second compression spring 505, so that the square frames 504 move toward the side of the support plate 501 and clamp the paper, thereby ensuring that the paper will not fall when moving inside the drying box 1, thereby ensuring the stability of paper drying.
