Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulp molding equipment, and in particular to high-efficiency and energy-saving pulp molding equipment. Background Technology
[0002] Pulp molding equipment is a specialized device that produces various environmentally friendly pulp products (such as packaging liners, tableware, and industrial cushioning components) by processing raw materials such as waste paper and plant fibers into pulp, followed by molding, dewatering, and drying. Its core function is to transform liquid pulp into solid products with specific shapes and strengths, making it a core link in the pulp molding industry chain.
[0003] Currently, pulp molding hot pressing equipment has the following problems in actual use: 1. The template size is too small. Traditionally, templates with a size of 950mm*950mm or less are used. The size of the molds that can be installed is small, resulting in low production capacity. If more production capacity is required, more equipment and more molds need to be invested, resulting in high overall investment costs.
[0004] 2. Using gear rack or chain drive as the driving source to drive the hot press mold to move along the guide rail, gear rack is prone to wear and needs to be replaced frequently, and chain drive has the risk of tooth skipping, which will cause the hot press mold to deviate from the translation trajectory.
[0005] 3. It is mainly driven by hydraulics, and the hot pressing mold is pushed by the hydraulic cylinder to complete the mold closing action. The risk of hydraulic oil leakage is high (especially in food-grade production scenarios), and the continuous operation of the hydraulic pump leads to increased energy consumption (the measured single unit power is ≥10kW).
[0006] 4. The template balance is difficult to control, manual adjustment is time-consuming (each adjustment takes ≥30 minutes), and the accuracy is low (flatness error ≥0.2mm). The auxiliary support structure is complex (multi-stage cylinder compensation system), increasing the equipment manufacturing cost by more than 20%. Utility Model Content

The lifting mechanism includes a second motor, a toggle link, and a crankshaft. The output shaft of the second motor is connected to the crankshaft, and both ends of the crankshaft are connected to a set of toggle links. The other end of the toggle link is hinged to the bottom surface of the lower template.
[0011] Preferably, both sets of the toggle linkages include a main drive rod, a support rod, a driven rod, and a lifting rod. The drive rod is hinged to one end of the crankshaft, and the other end of the drive rod is hinged to one side of the top of one of the support rods.

[0012] Preferably, the lifting mechanism further includes two auxiliary cylinders, the piston ends of which are respectively connected to the side of the lower mold.
[0013] Preferably, the frame also includes a column, a lower mold base, and a high-precision spring system. The four corners of the lower mold base are slidably connected to the column, and the lower mold is elastically mounted on the lower mold base through the high-precision spring system.
[0014] Preferably, heating tubes are provided inside both the upper mold and the lower mold, and vacuum tubes are inserted into one side of both the upper mold and the lower mold, with one end of the vacuum tube connected to a vacuum device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The template of this utility model consists of four 670mm*720mm templates forming a large template of 1350mm*1450mm. Compared with the traditional 950mm*950mm template, the number of holes is increased by 80%, the production capacity is increased by 44%, and the equipment investment is reduced by 43%.
[0017] This invention uses a linkage structure with a translation mechanism to convert rotational motion into linear motion, thereby translating the upper mold.

[0018] This invention replaces the traditional hydraulic drive with a servo toggle drive structure, avoiding the risk of hydraulic oil leakage contaminating the food-grade production environment, and reducing energy consumption by 40% compared to hydraulic drive.
[0019] This invention uses a high-precision spring system to elastically support the lower mold plate, which automatically compensates for the horizontal deviation of the mold plate during the pressing process and forces the parallelism of the upper and lower molds to be corrected, so that the lower mold always remains in a horizontal state, thereby improving the mold closing accuracy and product consistency, and reducing the investment cost compared to a multi-stage cylinder compensation system.
[0020] This utility model adopts a dual-station structure design. When one product forming device picks up material and closes the mold for forming, the other product forming device takes over the slurry suction mold and transfers the product that has been initially formed by slurry scooping to another station for further extrusion forming. This realizes the connection processing of the forming equipment, reduces the waiting time of the slurry scooping process, and increases the forming efficiency by 100%, greatly improving the working efficiency of the forming equipment.

Detailed Implementation
[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0030] This utility model provides a high-efficiency and energy-saving pulp molding equipment, such as... Figure 1-2 As shown, it includes a slurry tank 1, and a product forming device 2 is provided on both sides of the slurry tank 1. The two product forming devices 2 are symmetrically arranged with respect to the center line of the slurry tank 1, so that two workstations can be set up for the same slurry tank 1.
[0031] Furthermore, a slurry suction mold 11 is provided inside the slurry tank 1. The slurry suction mold 11 is used to suck up the slurry inside the slurry tank 1 and pre-form the slurry into an initial product shape. A lifting mechanism 12 is also provided at the top of the slurry tank 1. The movable end of the lifting mechanism 12 is connected to the slurry suction mold 11 to drive the slurry suction mold 11 to move up and down inside the slurry tank 1, so that the slurry suction mold 11 is lifted out of / into the tank from the slurry tank 1.
[0032] Because the slurry suction mold 11 has a fast slurry scooping speed, this application sets up a dual-station system to transfer the initially shaped products to separate extrusion molding. When one of the product molding devices 2 takes material and closes the mold to form the product, the slurry suction mold 11 performs another slurry scooping operation. At this time, the other product molding device 2 takes over from the slurry suction mold 11 and transfers the initially shaped products to another station for continued extrusion molding. This achieves seamless processing of the molding equipment, reduces the waiting time of the slurry scooping process, and increases the molding efficiency by 100%, greatly improving the working efficiency of the molding equipment.
[0033] Furthermore, the product forming device 2 includes a frame 21, a translation mechanism 22, an upper mold 23, a lower mold 24, and a lifting mechanism 25. Specifically, the translation mechanism 22 is fixedly mounted on one side of the top of the frame 21, and its movable end is connected to the upper mold 23, pushing the upper mold 23 to move left and right on the top of the slurry tank 1 so that the upper mold 23 cooperates with the slurry suction mold 11 raised to the top of the equipment to transfer the product. The lifting mechanism 25 is fixedly mounted in the middle of the bottom end of the frame 21, and its movable end is connected to the lower mold 24 so that the lower mold 24 cooperates with the upper mold 23 to complete the extrusion forming of the product.
[0034] Furthermore, the product forming device 2 also includes a linear module 26, which extends laterally through the top of the slurry pool 1. The upper mold 23 is mounted on the bottom of the linear module 26 to cooperate with the translation mechanism 22 to drive the lower mold 24 to make linear movements.
[0035] The molding principle is as follows: The suction mold 11 sucks up the slurry from the slurry pool 1 and pre-forms the slurry into an initial product shape. Then, the lifting mechanism 12 lifts the suction mold 11 to the top of the slurry pool 1. One of the product forming devices 2 is equipped with a translation mechanism 22 that drives the lower mold 23 to move horizontally along the straight module 26 until it moves above the suction mold 11. The pre-formed product on the suction mold 11 is then sucked up and repositioned. At this time, the upper mold 23 and the lower mold 24 are aligned vertically. The lifting mechanism 25 drives the lower mold 24 to move upward, thereby closing the upper mold 23 and the lower mold 24 and fixing the product in place. During the forming process, the suction mold 11 is reset and continues to repeat the slurry scooping action, while the other product forming device 2 cooperates with it to perform the next mold closing and forming process, and so on.
[0036] In this embodiment, the lifting mechanism 12 includes a first motor 121, a chain assembly 122, a connecting block 123, a fixed frame 124, and a lifting frame 125. The fixed frame 124 is fixedly installed on the top of the slurry tank 1, and the lifting frame 125 is slidably mounted on the fixed frame 124. The bottom of the lifting frame 125 is equipped with a slurry suction mold 11. The two ends of the chain assembly 122 are rotatably mounted on the upper and lower ends of the support, respectively. The chain of the chain assembly 122 is equipped with a connecting block 123, and the other end of the connecting block 123 is equipped with the lifting frame 125. The first motor 121 is fixedly installed on the bottom of the support, and its output shaft is connected to one end of the chain assembly 122 for transmission, so as to drive the chain assembly 122 to rotate and make the lifting frame 125 move up and down.
[0037] The lifting principle is as follows: After the suction mold 11 sucks up the slurry, the first motor 121 drives the chain assembly 122 to operate. The lifting frame 125, which is slidably mounted on the fixed frame 124, is lifted through the connecting block 123 until the suction mold 11 rises to be parallel with the upper mold 23. After the upper mold 23 and the suction mold 11 have completed the transfer, the first motor 121 reverses to reset the suction mold 11.
[0038] It can be explained here that the chain assembly 122 includes a chain and sprockets. The two sprockets are respectively mounted on the upper and lower ends of the fixed frame 124, and the chain is sleeved on the two sprockets. The chain can be turned by driving one of the sprockets through the first motor 121. The fixed frame 124 and the lifting frame 125 are slidably assembled by means of a sliding rod and sliding sleeve assembly.
[0039] The lifting action is performed by chain drive to improve the load-bearing capacity of the lifting system, thereby improving the stability of the equipment lifting.
[0040] In this embodiment, the translation mechanism 22 includes a translation motor 221, a main rotation shaft 222, a driven shaft 223, a first connecting rod 224, a second connecting rod 225, and a connecting shaft 226. The translation motor 221 is mounted on one side of the frame 21, and its output end is connected to the main rotation shaft 222. The top of the main rotation shaft 222 is fixedly connected to the first connecting rod 224. One end of the first connecting rod 224 is connected to the driven shaft 223. The top of the driven shaft 223 is fixedly connected to the second connecting rod 225. One end of the second connecting rod 225 is rotatably connected to the connecting shaft 226. The bottom of the connecting shaft 226 is fixedly connected to one side of the upper mold 23.
[0041] The principle of translation is as follows: The translation motor 221 drives the main rotating shaft 222 to rotate, thereby causing the first connecting rod 224 to rotate along the center line of the main rotating shaft 222. When one end of the first connecting rod 224 rotates, it drives the second connecting rod 225 to rotate through the driven shaft 223. Since the upper mold 23 is limited by the sliding of the linear module 26 and the connecting shaft 266 is fixedly connected to the upper mold 23, one end of the second connecting rod 225 can only rotate along the center line of the connecting shaft 226, thereby pushing the upper mold 23 connected by the connecting shaft 226.
[0042] The linkage structure of the translation mechanism, in conjunction with the linear module, converts rotational motion into linear motion, enabling the upper mold to translate. This replaces the traditional gear, rack, or chain drive, improving not only the accuracy of translation but also the load-bearing capacity of the translation mechanism. Furthermore, the linkage structure offers flexible movement trajectory and effectively reduces frictional wear, allowing for over 100,000 uses.
[0043] In this embodiment, the lifting mechanism 25 includes a second motor 251, a toggle link 253, and a crankshaft 252. The output shaft of the second motor 251 is connected to the crankshaft 252. Both ends of the crankshaft 252 are connected to a set of toggle links 253. The other end of the toggle link 253 is hinged to the bottom surface of the lower template.
[0044] Specifically, both sets of toggle linkages 253 include a main drive rod 2531, a support rod 2532, a driven rod 2533, and a lifting rod 2534. The drive rod is hinged to one end of the crankshaft 252, and the other end of the drive rod is hinged to one side of the top of one of the support rods 2532. The two support rods 2532 are vertically arranged, and their other top sides are hinged to a driven rod 2533. The top of each of the two support rods 2532 is hinged to a lifting rod 2534, and the other end of the lifting rod 2534 is hinged to the bottom of the lower mold 24.
[0045] The lifting principle is as follows: The second motor drives the crankshaft 252 to rotate, and the downward rotational motion is converted into linear motion by the toggle link 253, thereby driving the lower mold to rise / fall. Specifically, the rotation of the crankshaft 252 drives one end of the main drive rod 2531 to rotate, and the other end of the main drive rod 2531 then drives the top of the support rod 2532 to move, causing the support rod 2532 to tilt or move vertically. Under the action of the driven rod 2533, it drives another support rod 2532 to move synchronously, thereby causing the lifting rod 2534 to tilt or move vertically, so as to pull or push the lower mold 24 to perform lifting and lowering motion, realizing the mold closing / opening operation of the upper mold 23 and the lower mold 24.
[0046] By replacing the traditional hydraulic drive with a servo toggle drive structure, the risk of hydraulic oil leakage contaminating the food-grade production environment is avoided, and energy consumption is reduced by 40% compared to hydraulic drive.
[0047] Furthermore, the lifting mechanism 25 also includes two auxiliary cylinders 254, the piston ends of which are connected to the sides of the lower mold 24. The auxiliary cylinders 254 are used to assist the lifting mechanism 25 in lifting the lower mold, thereby improving the stability of the lower mold's lifting and lowering.
[0048] In this embodiment, the frame 21 also includes a column 211, a lower mold base 212, and a high-precision spring system 213. The four corners of the lower mold base 212 are slidably connected to the column 211. The lower mold 24 is elastically mounted on the lower mold base 212 through the high-precision spring system 213. The lifting mechanism 25 and the auxiliary cylinder 254 are both connected and assembled with the lower mold base 212, thereby driving the lower mold 24 to rise and fall.
[0049] Specifically, the high-precision spring system 213 includes several springs arranged in a rectangular array between the lower mold 24 and the lower mold base 212, which are used to elastically support the lower mold plate 24, so that it automatically compensates for the horizontal deviation of the mold plate during the mold pressing moment and process, and forcibly corrects the parallelism of the upper and lower molds 24, so that the lower mold 24 always keeps in a horizontal state, thereby improving the mold closing accuracy and product consistency, and reducing the investment cost compared with the multi-stage cylinder compensation system.
[0050] In this embodiment, heating tubes 27 are provided inside both the upper mold 23 and the lower mold 24 for hot pressing the product during mold closing to ensure product molding. Vacuum tubes 28 are inserted into one side of both the upper mold 23 and the lower mold 24, and one end of the vacuum tube 28 is connected to a vacuum device. It can be explained here that both the upper mold 23 and the lower mold 24 are provided with several micro-holes, which are used to adsorb products through vacuum tubes and connected external vacuum devices. This vacuum adsorption structure is used when the upper mold 13 picks up the product from the suction mold 11 and transfers the product, and when the lower mold 24 opens to adsorb the product.
[0051] In this embodiment, both the upper mold 23 and the lower mold 24 are composed of four 670mm*720mm templates. The four 670mm*720mm templates form a large 1350mm*1450mm template. Taking the production of 90 cup lids as an example: the number of cavities in the 1350mm*1450mm template mold is increased by 80% compared to the traditional 950mm*950mm template mold, resulting in a 44% increase in production capacity. Taking the daily production of 6 tons of 90 cup lids as an example: the equipment investment for the 1350mm*1450mm template is reduced by 43% compared to the traditional 950mm*950mm template equipment.
[0052] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
