Description

Technical Field

[0001] The utility model relates to the technical field of pulp equipment, in particular to a turnover type fine paper machine. Background Art

[0002] Pulp molding is formed by vacuum suction filtration. The fibers in the pulp are evenly deposited on the molding net on the surface of the molding mold under vacuum environment, and a large amount of water is taken away during vacuum suction. When the required thickness of the product is reached, the molding mold is removed from the slurry and combined with the upper mold for extrusion and dehydration. During slurry suction, it is divided into positive slurry suction and reverse slurry suction according to different slurry suction directions. Positive slurry suction means that the direction of water suction by the mold is consistent with the direction of gravity, that is, the molding surface of the mold faces upward and sucks water downward; during reverse slurry suction, the direction of water suction is opposite to the direction of gravity, that is, the molding surface of the mold faces downward and sucks water upward.

[0003] The two slurry suction methods have their own characteristics. The positive slurry suction structure is relatively simple and the equipment cost is low, but the product has limitations. For products with complex structures, such as two relatively close bottom connections of the slope, there will be local slurry pockets after the water comes out. At this time, the rest of the parts are covered with fibers, and there is still slurry here. Continue to vacuum. The resistance of sucking air is less than the resistance of sucking water. A large amount of air will flow into the fiber-covered area, and the pressure difference inside and outside the molding mold will decrease rapidly, resulting in weak slurry suction at the slurry pocket, poor fiber adhesion, and will not be concentrated on the surface for molding. A bridge situation will be formed in the air, affecting product quality and making it difficult to achieve satisfactory results. Reverse slurry suction is just the opposite. The equipment cost is high, but it can achieve the production of complex products.

[0004] There are high-quality flip machines on the market. A flip molding lower mold assembly is set above the pulp box. The molding lower mold assembly consists of a support frame, a flip shaft and a flip drive module. Four guide sleeves are set at the four corners of the support frame to ensure the lifting accuracy; four pull rods are set on the frame, and the hydraulic cylinder above the frame is used to achieve up and down movement in the slurry suction position, flip position and mold exchange position. Two bearing boxes are set on the support frame to support the flip shaft to flip the slurry suction and dehydration. The slurry suction molding air chamber is configured in the middle of the flip shaft, and the other side is a balancing weight. The flip drive module is arranged on one side of the flip shaft, and the torque is transmitted through the gear pair to achieve the flipping action.

[0005] Although the above-mentioned flip-type fine machine can meet the reverse slurry absorption process to avoid bridging phenomenon, a support frame needs to be set at the bottom of the molding lower mold to accommodate the flip axis assembly. The support frame is a hollow frame structure. Since the flip axis assembly needs to be flipped inside the frame, the size of the support frame is very large, which makes the overall horizontal and vertical dimensions of the frame of the fine machine large, and it is inconvenient for the operator to change and adjust the mold on both sides of the frame.

The upper forming mold 2 and the lower forming mold 3 can form an integral mold of the paper product after being buckled. In this embodiment, the upper forming mold 2 can move on the upper frame 11. After the wet blank is formed between the upper forming mold 2 and the lower forming mold 3, the upper forming mold 2 moves to transfer the product.

[0039] The molding lower mold 3 is the core component of the equipment to realize flipping and slurry suction. The molding lower mold 3 includes a lower mold body 31, a lifting module 32, a hanger 33, a flip shaft assembly 34, a suction end support assembly 35, a driving end support assembly 36 and a hanger 37. The lower mold body 31 forms a complete product mold after being molded with the molding upper mold 2. There is an air chamber in the lower mold body 31, through which the slurry suction operation can be performed. The lower mold body 31 is fixedly assembled on the flip shaft assembly 34. When the flip shaft assembly 34 rotates, it can drive the lower mold body 31 to rotate circumferentially and adjust the direction of the lower mold body 31. When the lower mold body 31 is facing downward, slurry suction can be performed. When the lower mold body 31 is facing upward, it can be closed with the molding upper mold 2 to transfer the wet blank to the molding upper mold 2.

[0040] The suction end support assembly 35 and the drive end support assembly 36 are respectively fixedly assembled on the two ends of the flip shaft assembly 34, and a closed structure is formed between the suction end support assembly 35, the drive end support assembly 36 and the flip shaft assembly 34, so that the suction end support assembly 35, the drive end support assembly 36 and the flip shaft assembly 34 form a whole, and the suction end support assembly 35 and the drive end support assembly 36 respectively support the two ends of the flip shaft assembly 34.

The hanger 33, the suction end support assembly 35 and the driving end support assembly 36 are connected to form a whole by the hanger rod 37, and the suction end support assembly 35 and the driving end support assembly 36 replace the existing support frame structure, which can reduce the relative size of the frame 1, facilitate the operator's operation, and save site space.

[0042] The lifting module 32 is fixedly mounted on the upper frame 11, and is in transmission connection with the hanger 33. The lifting module 32 is used to drive the hanger 33 to move up and down, thereby driving the vertical position of the flip shaft assembly 34 and the lower mold body 31, and completing the movement of the lower mold body 31 in the three positions of the slurry suction position, the flip position and the transfer position. In this embodiment, the lifting module 32 is a hydraulic cylinder 7.

[0043] The three workstations of the slurry suction position, the flip position and the transfer position are distributed in sequence from bottom to top. When the lower mold body 31 is in the slurry suction position, the flip shaft assembly 34 performs reverse slurry suction to form a wet blank in the lower mold body 31. When the lower mold body 31 is in the flip position, it rotates circumferentially to change the orientation of the lower mold body 31 and rotates the lower mold body 31 from downward to upward. When the lower mold body 31 is in the transfer position, it completes the mold closing with the forming upper mold 2 and transfers the wet blank to the forming upper mold 2. When the hydraulic cylinder 7 drives the lower mold body 31 to move from the slurry suction position to the flip position or from the transfer position to the flip position, the flip shaft assembly 34 rotates in situ at the flip position to change the direction of the lower mold body 31, so as to realize the work of slurry suction to form a wet blank and transfer the wet blank to the forming upper mold 2.

When the turning shaft assembly 34 rotates, the lower mold body 31 on it can be immersed in the pulp in the box body 41 to absorb the pulp, or the lower mold body 31 on it can be rotated upward to discharge the pulp and transfer the wet blank.

[0045] In this embodiment, the slurry suction and dehydration pipe on the suction end support assembly 35 side of the flip shaft assembly 34 comes out from the rear of the machine and can be placed in the ditch, and the remaining pipes are in the air, so there are no redundant pipes around the machine, and the layout is simple and easy to maintain.

[0046] The two ends of the flip shaft assembly 34 of the forming lower mold 3 of the flip-type boutique machine are fixedly assembled with the suction end support assembly 35 and the driving end support assembly 36 respectively, and the three form a closed structure as a whole. The hanger 33 is connected with the suction end support assembly 35 and the driving end support assembly 36 through the hanger 37. The lifting module 32 is used to drive the hanger 33 to rise and fall, which can drive the lower mold body 31, the flip shaft assembly 34, the suction end support assembly 35, and the driving end support assembly 36 to rise and fall synchronously. The support frame structure to support the flip shaft assembly 34 is omitted, and the box body 41 of the slurry box assembly 4 can well accommodate the lower mold body 31 and the flip shaft assembly 34 into the box body 41, thereby reducing the size of the box body 41, thereby reducing the overall structure of the frame 1, which is convenient for the operator to operate.

[0047] Preferably, both the suction-end support assembly 35 and the driving-end support assembly 36 include a support plate 38 , on which a guide sleeve 381 is provided, and the guide sleeve 381 is sleeved on the outer side of the guide column 13 .

[0048] A guide sleeve 381 is provided on the support plate 38 of the suction end support assembly 35 and the driving end support assembly 36. The support plate 38 is assembled with the guide column 13 through the guide sleeve 381 to form a guiding fit. A total of two sets of guiding structures are formed between the support plate 38 and the guide column 13, and between the suspension rod 37 and the upper frame 11, which increases the stability of the lower molding mold 3 when moving.

[0049] Preferably, the guide column 13 and the suspension rod 37 are arranged offset in the horizontal direction, and the center line of the guide sleeve 381 deviates from the center line of the suspension rod 37.

[0050] The guide column 13 and the suspension rod 37 deviate from each other in the horizontal direction, so that the guide plane between the guide sleeve 381 and the guide column 13 and the guide plane between the suspension rod 37 and the upper frame 11 do not overlap, and the guidance is stable and accurate.

[0051] Preferably, it further comprises a hot pressing upper die 5 and a hot pressing lower die 6, wherein the hot pressing upper die 5 is assembled on the upper frame 11, and the hot pressing lower die 6 is assembled on the lower frame 12;

The molding lower mold 3 is guided and assembled with the first guide column 131 and the second guide column 132, and the hot pressing lower mold 6 is guided and transferred with the second guide column 132 and the third guide column 133.

[0053] The hot pressing lower die 6 is guided and assembled with the second guide column 132 and the third guide column 133, while the molding lower die 3 is guided and assembled with the first guide column 131 and the second guide column 132. The hot pressing lower die 6 and the molding lower die 3 share the second guide column 132 arranged in pairs, which reduces the number of guide columns 13. This structure shortens the length of the frame 1, simplifies the structure of the boutique machine, occupies a small space, and is easy to maintain.

[0054] The existing high-quality machines on the market have four guide posts 13 arranged on the lower forming die 3 and the lower hot pressing die 6 during the guide assembly, and a total of eight guide posts 13 are required on the frame 1, which increases the length of the frame 1, increases the translation distance of the upper forming die 2 and the upper hot pressing die 5, increases the translation time and parts cost, and increases the product production cycle. However, the frame 1 in this application requires a total of six guide posts 13, the overall length is short, the translation distance of the upper forming die 2 and the upper hot pressing die 5 is short, and the parts cost and production cycle are correspondingly reduced.

[0055] Preferably, a slide rail 111 is installed on the upper frame 11 in the horizontal direction, and the hot pressing upper mold 5 and the forming upper mold 2 are both guided and installed on the slide rail 111, and the hot pressing upper mold 5 and the forming upper mold 2 are fixedly connected.

[0056] The upper frame 11 is provided with a slide rail 111 to ensure the precise movement of the molding upper die 2 and the hot pressing upper die 5. After the hot pressing upper die 5 is fixedly connected to the molding upper die 2, the two form a whole and realize synchronous movement. In this embodiment, the upper frame 11 is provided with a screw nut mechanism 112 and a drive motor 113, and the screw nut mechanism 112 is transmission-connected between the drive motor 113 and the hot pressing upper die 5. The hot pressing upper die 5 and the molding upper die 2 are precisely moved by the screw nut mechanism 112, so that the product on the molding upper die 2 can be transferred to the hot pressing lower die 6, and the hot pressing upper die 5 can be moved to the upper side of the hot pressing lower die 6. In this embodiment, the hot pressing upper die 5 and the molding upper die 2 are fixedly connected by bolts and structural plates, and the molding upper die 2 is guided and assembled on the slide rail 111. After the hot pressing upper die 5 and the molding upper die 2 are connected as a whole, the screw nut mechanism 112 only needs to be transmission-connected with the hot pressing upper die 5 to drive the molding upper die 2 to move synchronously.

[0057] In this embodiment, a hydraulic cylinder 7 is provided at the bottom of the hot pressing lower die 6, and there are three hydraulic cylinders 7 in total. The three hydraulic cylinders 7 act together on the hot pressing lower die 6 to achieve multi-point support, so that the pressure distribution of the hot pressing lower die 6 is balanced. The three hydraulic cylinders 7 can drive the hot pressing lower die 6 to move upward, and the hot pressing lower die 6 is molded with the hot pressing lower die 6 to achieve hot pressing operation. When the hot pressing lower die 6 is raised or lowered, the middle cylinder of the three hydraulic cylinders 7 absorbs oil from the cylinders on both sides, that is, all the hydraulic oil drives the cylinder in the middle to move, so that the hot pressing lower die 6 can be quickly raised and lowered; when the hot pressing lower die 6 is molded with the hot pressing upper die 5, the three hydraulic cylinders 7 work together to achieve high-pressure hot pressing.

The center of gravity of the molding lower mold 3 can be adjusted on the flip centerline by adjusting the weight of the first counterweights 39. A second counterweight 30 is arranged on the side of the hanger 33 close to the suction end support assembly 35. The center of gravity of the molding lower mold 3 can be adjusted to be located on the neutral plane of the molding lower mold 3 by the second counterweight 30.

[0060] Different molds will produce different gravity torques. By setting the first counterweight 39 and the second counterweight 30, the torque balance can be adjusted accurately in all directions. The suction end of the flip shaft assembly 34 will form the air chamber plate of the lower mold 3. Setting the first counterweight 39 can balance its gravity so that the center of gravity of the flip shaft assembly 34 is located on its flip center line. The driving end of the flip shaft assembly 34 includes a motor, a reducer 343, a gear pair and other structures. The weight is large, which makes the weight difference between the suction end support assembly 35 and the driving end support assembly 36 large, which will produce unbalanced torque on the left and right.

[0069] Preferably, the water baffle 43 divides the box body 41 into a slurry suction area 46 and an overflow trough area 47, the flip shaft assembly 34 is arranged at the slurry suction area, and the slurry box assembly 4 also includes a slurry return pump 48 and a slurry return pipe 49, the slurry return pump 48 is connected to the overflow trough area 47, and the slurry return pipe 49 is connected between the slurry return pump 48 and the slurry suction area 46.

[0070] The box body 41 is divided into a slurry suction area 46 and an overflow trough area 47 by a water baffle 43. The height of the water baffle 43 is the highest liquid level in the slurry suction area 46. When the wet blank is transferred and the slurry water is stirred, the slurry water exceeding the highest liquid level flows to the overflow trough area 47 to prevent the slurry water from splashing to the outside; the return slurry pump 48 can transport the slurry water in the overflow trough area 47 back to the slurry suction area 46 through the return slurry pipe 49, retaining the overflow and slurry water recovery functions, while also avoiding the possibility of cross contamination caused by concentrated reflux through the reflux pipe.

[0071] The existing overflow is to set up a return pipe and let the slurry return by its own weight. The return pipe will have a state where the lower half is slurry and the upper half is air. There is no slurry flowing in the upper half. In a high humidity environment, the fiber is an organic matter and will quickly become moldy. When the moldy fiber blocks grow larger and larger, they will fall off and then gather together and be transported to the slurry supply pipeline through the slurry supply pump, polluting the entire slurry supply system.

[0072] In summary, the embodiment of the utility model provides a flip-type fine machine, in which the two ends of the flip shaft assembly of the molding lower mold are respectively fixedly assembled with the suction end support assembly and the driving end support assembly, and the three form a closed structure as a whole, and the hanger is connected to the suction end support assembly and the driving end support assembly through a hanger rod. The lifting and lowering of the hanger can drive the lower mold body, the flip shaft assembly, the suction end support assembly, and the driving end support assembly to rise and fall synchronously by using the lifting module to drive the hanger to rise and fall, and the support frame structure to support the flip shaft assembly is omitted. The box body of the pulp box assembly can well accommodate the lower mold body and the flip shaft assembly into the box body, thereby reducing the size of the box body, thereby reducing the overall structure of the frame, and facilitating the operator's operation.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
