Description

Technical Field

[0001] This utility model belongs to the field of pulp molding production technology, specifically relating to a pulp molding drum machine. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, shaping it into specific paper products using special molds on a molding machine. The process involves pulping, adsorption molding, drying, and setting, and is environmentally friendly; it is recyclable. Besides being used for lunch boxes and tableware, pulp molding is increasingly used for industrial cushioning packaging, improving the recycling rate of waste paper resources.

[0003] The process of making pulp molding generally involves pulp forming, drying, hot pressing and shaping, and trimming. However, in existing pulp molding and drying equipment, after the pulp blanks are dried and formed, the pulp blanks are transferred by an external discharge transfer mechanism. Since the pulp molding drum and the discharge transfer mechanism in the pulp molding and drying equipment are driven by two separate drive systems, the pulp blanks in the pulp molding drum need to be intermittently paused while waiting for the discharge transfer mechanism to pick up the material, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of low production efficiency in existing pulp molding and drying equipment, and to provide a pulp molding drum machine that improves production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The pulp molding drum machine includes a frame, a pulp adsorption forming drum, a material transfer mechanism, and a drive unit.

[0007] The frame is equipped with a slurry adsorption box, which has a paper mold forming processing chamber located on the inner side. The front opening of the paper mold forming processing chamber forms a discharge port, and the bottom of the paper mold forming processing chamber forms a slurry pool. A drying heater is provided at the top of the paper mold forming processing chamber, and a burr cleaner is provided on the rear wall of the paper mold forming processing chamber.

[0008] The paper mold adsorption forming drum is connected to the slurry adsorption box via a main shaft. The outer circumference of the paper mold adsorption drum in the direction of rotation is provided with a paper mold forming adsorption groove. The paper mold forming adsorption groove is provided with a vacuum adsorption hole. Under the operation of the paper mold adsorption drum, the slurry flows sequentially through the slurry pool, the rough edge cleaner, the drying heater and the discharge port.

[0009] The discharge transfer mechanism is located on the outside of the discharge port on the frame and is used to transfer the paper mold blanks flowing to the discharge port in the paper mold forming adsorption tank to the outside.

[0010] The driving device includes a drive motor and a divider. The drive motor is connected to the input end of the divider. One output end of the divider is connected to the main shaft. The other output end of the divider is connected to the discharge transfer mechanism through a transmission assembly. This allows the paper mold adsorption forming drum and the discharge transfer mechanism to operate periodically at a preset transmission ratio. As a result, when any paper mold forming adsorption tank with paper mold blanks flows through the discharge port, the paper mold blanks on the paper mold forming adsorption tank are transferred from the discharge port to the outside by the discharge transfer mechanism.

[0011] Compared with existing technologies, this utility model's pulp molding drum machine, through the adoption of an integrated drive device, links and controls the paper mold adsorption and forming drum with the discharge transfer mechanism, achieving periodic synchronous operation of the two under a preset transmission ratio. This effectively solves the problem of intermittent pauses required for discharge in traditional equipment due to separate drives. The drive device ensures that the discharge transfer mechanism can promptly complete the transfer operation of each forming adsorption tank containing a paper mold blank as it flows through the discharge port without interrupting the continuous operation of the paper mold adsorption and forming drum. This significantly improves the continuity of equipment operation and production efficiency. Simultaneously, this structural design simplifies the transmission system, reduces equipment manufacturing costs and energy consumption, and is conducive to improving the overall efficiency of waste paper resource recycling.

[0012] Furthermore, the material transfer mechanism includes a set of swing components, suction cup components and a synchronization rod located on both sides of the discharge port. The swing components include a triangular swing member, a transmission rod and a turntable. The suction cup components are provided with a guide component that slides with the frame on the rear side.

[0013] Furthermore, the guiding component includes a guide frame, with sliding guide grooves on both sides of the guide frame. The frame is provided with guide wheels on both sides of the discharge port, which slide in cooperation with the corresponding sliding guide grooves. With this arrangement, the precise cooperation between the guide wheels and the sliding guide grooves provides stable and accurate linear guidance for the reciprocating motion of the suction cup component, effectively preventing it from deviating or getting stuck during movement. This ensures the accuracy of the material pick-up and drop-off position and improves the stability and reliability of the entire material transfer process.

[0014] Furthermore, two, four, or eight paper mold forming adsorption tanks are symmetrically arranged on the outer periphery along the rotation direction of the paper mold adsorption drum.

[0015] Furthermore, multiple paper mold forming adsorption grooves are provided along the length direction of the paper mold adsorption drum; by setting multiple paper mold forming adsorption grooves along the length direction of the drum, the axial space of the drum is effectively utilized, enabling the equipment to form multiple paper mold blanks simultaneously in a single operation, significantly improving the production efficiency and equipment utilization rate per unit time.

[0016] Furthermore, an adsorption tank cleaner is provided inside the paper mold forming processing cavity on the lower side of the discharge position for cleaning the paper mold forming adsorption tank. With this configuration, by setting the adsorption tank cleaner on the lower side of the discharge position, the forming adsorption tank can be automatically cleaned after each discharge, effectively removing residual fibers and impurities, ensuring the stability of subsequent adsorption forming quality and the long-term smooth operation of the mold, and guaranteeing the continuity of production and the consistency of products.

[0017] Furthermore, it also includes a water pumping system, which provides cleaning water for the adsorption tank cleaner and the deburring cleaner. By setting up a centralized water pumping system to provide cleaning water for both the adsorption tank cleaner and the deburring cleaner, the equipment pipeline layout is simplified, the intensive use of water resources and the automation of cleaning operations are realized, and the overall performance and energy efficiency of the equipment are effectively improved.

[0018] Furthermore, a vacuum system is included to provide negative pressure to the vacuum adsorption holes. By setting up a dedicated vacuum system to provide stable and reliable negative pressure to the vacuum adsorption holes, it is ensured that the paper mold blanks are firmly adsorbed during the forming, transfer and cleaning processes, effectively preventing them from deforming or falling off, thereby ensuring the smoothness of the production process and the stability of product quality.

[0019] Furthermore, the transmission component is a belt drive component; by adopting a belt drive component, its characteristics of buffering, vibration reduction and overload protection are utilized to achieve smooth and low-noise power transmission between the drive device and the actuator, while simplifying the structure and reducing installation accuracy requirements and maintenance costs.

Detailed Implementation

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] See Figures 1 to 6 The pulp molding drum machine of this utility model includes a frame 1, a paper mold adsorption forming drum 2, a material transfer mechanism 3, and a drive device 4.

[0029] The frame 1 is equipped with a slurry adsorption box 11. The slurry box has a paper mold forming processing cavity 12 located on the inner side. The front opening of the paper mold forming processing cavity 12 forms a discharge port 13. The bottom of the paper mold forming processing cavity 12 forms a slurry pool 14. The top of the paper mold forming processing cavity 12 is equipped with a drying heater (not shown in the figure), and the rear wall of the paper mold forming processing cavity 12 is equipped with a rough edge cleaner (not shown in the figure).

[0030] The paper mold adsorption forming drum 2 is rotatably connected to the slurry adsorption box 11 via the main shaft 20. The outer periphery of the paper mold adsorption drum in the direction of rotation is provided with a paper mold forming adsorption groove 21. The paper mold forming adsorption groove 21 is provided with vacuum adsorption holes. Under the operation of the paper mold adsorption drum, the slurry forming adsorption groove 21 flows sequentially through the slurry pool 14, the burr cleaner, the drying heater and the discharge port 13. This realizes that after the slurry in the slurry pool 14 is formed into a paper mold blank by adsorption forming, the burr cleaner washes and removes the burrs on the outer periphery of the paper mold blank and the drying heater dries and shapes it, and finally it is transferred outward from the discharge port 13.

[0031] The discharge transfer mechanism 3 is located outside the discharge port 13 on the frame 1 and is used to transfer the paper mold blank in the paper mold forming adsorption tank 21 flowing to the discharge port 13 to the outside.

[0032] The driving device 4 includes a drive motor 41, a reducer 42, and a divider 43. The drive motor 41 is connected to the input end of the divider 43 via the reducer 42. One output end of the divider 43 is connected to the main shaft 20, and the other output end of the divider 43 is connected to the discharge transfer mechanism 3 via the transmission assembly 44. This allows the paper mold adsorption forming drum 2 and the discharge transfer mechanism 3 to operate periodically at a preset transmission ratio. Thus, when any paper mold forming adsorption tank 21 containing a paper mold blank flows through the discharge port 13, the paper mold blank on the paper mold forming adsorption tank 21 is transferred from the discharge port 13 to the outside by the discharge transfer mechanism 3.

[0033] Compared with existing technologies, the pulp molding drum machine of this invention, through the use of an integrated drive device 4, links and controls the paper mold adsorption and forming drum 2 and the discharge transfer mechanism 3, achieving periodic synchronous operation of the two under a preset transmission ratio. This effectively solves the problem of intermittent pauses required for discharge in traditional equipment due to separate drives. The drive device 4 ensures that the discharge transfer mechanism 3 can promptly complete the transfer operation of each forming adsorption tank containing a paper mold blank as it flows through the discharge port 13 without interrupting the continuous operation of the paper mold adsorption and forming drum 2, thus significantly improving the continuity of equipment operation and production efficiency. Simultaneously, this structural design simplifies the transmission system, reduces equipment manufacturing costs and energy consumption, and is conducive to improving the overall efficiency of waste paper resource recycling.

[0034] See Figures 1 to 6 In one embodiment, the discharge transfer mechanism 3 includes a set of swing components 31, suction cup components 32, and a synchronizing rod 33 located on both sides of the discharge port 13. The swing components 31 include a triangular swing member 34, a transmission rod 35, and a turntable 36. The suction cup component 32 has a guide component that slides with the frame 1 at its rear. The triangular swing member 34 is rotatably connected to the frame 1 at its center. Both ends of the triangular swing member 34 are rotatably connected to one end of the transmission rod 35 and the guide component, respectively. The two turntables 36 are rotatably connected to both sides of the frame 1, and the two turntables 36 rotate synchronously through the synchronizing rod 33. The transmission rod 35... The other end is rotatably connected to the turntable 36 in the radial direction; the drive device 4 drives the turntable 36 to rotate circumferentially, causing the transmission rod 35 to drive the triangular swing member 34 to swing periodically relative to each other, so that the suction cup assembly 32 can work back and forth at the discharge port 13 and vertically downward under the guidance of the guide assembly; by setting the discharge transfer mechanism 3 composed of the turntable 36, the transmission rod 35 and the triangular swing member 34, the rotational motion of the drive device 4 is converted into the precise and stable reciprocating motion of the suction cup assembly 32 between the discharge port 13 and the lower station, realizing the efficient and reliable automated gripping and transfer of the paper mold blank, and further ensuring continuous synchronous production with the main drum machine.

[0035] See Figures 1 to 6 In one embodiment, the guiding assembly includes a guide frame 37, with sliding guide grooves 38 on both sides of the guide frame 37. The frame 1 is provided with guide wheels 39 on both sides of the discharge port 13, which slide in cooperation with the corresponding sliding guide grooves 38. With this arrangement, the precise cooperation between the guide wheels 39 and the sliding guide grooves 38 provides stable and accurate linear guidance for the reciprocating motion of the suction cup assembly 32, effectively preventing it from deviating or getting stuck during movement, thereby ensuring the accuracy of the material pick-up and drop-off position and improving the smoothness and reliability of the entire material transfer process.

[0036] See Figures 1 to 6 In one embodiment, two paper mold forming adsorption tanks 21 are symmetrically arranged on the outer periphery of the paper mold adsorption drum along the rotation direction, and the periodic rotational speed ratio of the paper mold adsorption forming drum 2 to the discharge transfer mechanism 3 is 1:2; or, four paper mold forming adsorption tanks 21 are evenly distributed on the outer periphery of the paper mold adsorption drum along the rotation direction, and the periodic rotational speed ratio of the paper mold adsorption forming drum 2 to the discharge transfer mechanism 3 is 1:4; or, eight paper mold forming adsorption tanks 21 are evenly distributed on the outer periphery of the paper mold adsorption drum along the rotation direction, and the periodic rotational speed ratio of the paper mold adsorption forming drum 2 to the discharge transfer mechanism 3 is 1:8. By setting up such a configuration and establishing a specific matching relationship between the number of drum forming tanks and the transmission ratio of the master and slave mechanisms, it is ensured that no matter how the number of drum stations increases, the discharge transfer mechanism 3 can accurately and synchronously complete the gripping of each blank at a corresponding high frequency, thereby improving the single-cycle capacity of the equipment while absolutely guaranteeing the synchronicity and coordination of continuous production.

[0037] See Figures 1 to 6 In one embodiment, multiple paper mold forming adsorption grooves 21 are provided along the length direction of the paper mold adsorption drum. By setting multiple paper mold forming adsorption grooves 21 along the length direction of the drum, the axial space of the drum is effectively utilized, enabling the equipment to form multiple paper mold blanks simultaneously in a single operation, which significantly improves the production efficiency and equipment utilization rate per unit time.

[0038] See Figures 1 to 6 In one embodiment, the paper mold forming processing cavity 12 is provided with an adsorption tank cleaner (not shown) for cleaning the paper mold forming adsorption tank 21 located below the discharge position. With this arrangement, by setting the adsorption tank cleaner below the discharge position, the forming adsorption tank can be automatically cleaned after each discharge, effectively removing residual fibers and impurities, ensuring the stability of subsequent adsorption forming quality and the long-term smoothness of the mold, and ensuring the continuity of production and the consistency of products.

[0039] See Figures 1 to 6In one embodiment, a water pumping system (not shown) is also included, which provides cleaning water for the adsorption tank cleaner and the deburring cleaner. By setting up a centralized water pumping system to provide cleaning water for both the adsorption tank cleaner and the deburring cleaner, the equipment pipeline layout is simplified, the intensive use of water resources and the automation of cleaning operations are realized, and the overall performance and energy efficiency of the equipment are effectively improved.

[0040] See Figures 1 to 6 In one embodiment, a vacuum system 5 is also included, which is used to provide negative pressure to the vacuum adsorption hole. By setting up a dedicated vacuum system 5, a stable and reliable negative pressure is provided to the vacuum adsorption hole, ensuring that the paper mold blank is firmly adsorbed during the forming, transfer and cleaning process, effectively preventing its deformation or fall off, thereby ensuring the smooth production process and stable product quality.

[0041] See Figures 1 to 6 In one embodiment, the transmission component 44 is a belt drive component 44. By using the belt drive component 44, the characteristics of buffering, vibration reduction and overload protection are utilized to achieve smooth and low-noise power transmission between the drive device 4 and the actuator, while simplifying the structure and reducing the installation accuracy requirements and maintenance costs.
