Description

Technical Field

[0001] This utility model relates to the field of three-dimensional papermaking technology, and in particular to a pulp molding product forming equipment. Background Technology

[0002] Pulp molding equipment uses waste paper as raw material to mold paper products into specific shapes using special molds on molding equipment, such as egg cartons, lunch boxes, and tableware.

[0003] The production process consists of pulping, adsorption molding, and other steps. The pulping unit crushes waste paper, cardboard, or plant fiber raw materials, and the crushed pulp is transported to the molding box. The upper mold is connected to the drive end of the lifting mechanism. The lifting mechanism drives the upper mold to descend and press against the lower mold. The lower mold is driven by a hydraulic telescopic rod to sink into the molding box. The pulp in the molding box is then poured into the molding cavity formed between the upper and lower molds. The lower mold is then driven by the hydraulic telescopic rod to rise with the pulp. Then, a vacuum adsorption system is used to create negative pressure to remove moisture, resulting in the molded blank.

[0004] Existing pulp molding equipment may experience fiber or impurity buildup in the mold's micropores during production due to excessively coarse pulp fibers or fiber residue on the mold surface. This blockage reduces the mold's adsorption efficiency, obstructs the drainage of moisture and air, and leads to insufficient dewatering of the paper blank, prolonged molding cycles, and ultimately affects overall production efficiency. Currently, when the mold micropores become clogged, unplanned shutdowns are commonly performed to clear or clean the mold. This reduces equipment utilization, increases manual maintenance costs, and wastes time. Furthermore, frequent maintenance may increase the likelihood of personnel being exposed to high-temperature, high-pressure equipment or chemical cleaning agents. Utility Model Content

[0031] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0032] like Figures 1-7 As shown, a pulp molding product forming equipment includes a pulping mechanism and an adsorption molding mechanism 300. The pulping mechanism is used to make a uniform pulp suspension from waste paper, cardboard, or plant fiber raw materials and to deliver the pulp to the adsorption molding mechanism 300. The adsorption molding mechanism 300 includes a first frame 301, a vacuum adsorption system, a molding box 304, a molding die, and a lifting mechanism. The vacuum adsorption system is located at the bottom of the first frame 301, the molding box 304 is located inside the first frame 301, and the molding die is located above the molding box 304. The pulping mechanism is connected to the molding box 304 and is used to deliver the pulp to the molding box. The top of the first frame 301 is provided with a lifting mechanism for driving the molding die to rise and fall. The molding die has mold micropores 308 distributed on it and connected to the vacuum adsorption system. The vacuum adsorption system generates and maintains a stable negative pressure required for the molding process through the micropores, driving the dewatering process.

[0033] The vacuum adsorption system includes a vacuum negative pressure device 302 and a vacuum pipeline 303. The vacuum negative pressure device 302 is installed at the bottom of the first frame 301 and is connected to the mold micro-holes 308 on the molding die through the vacuum pipeline 303. Here, the vacuum negative pressure device 302 is a pump that can generate negative pressure, such as a vacuum pump. The vacuum negative pressure device 302 generates negative pressure in the micro-holes through the negative pressure suction function, sucking out the water in the slurry. The fibers in the slurry remain in the molding die, thereby obtaining the corresponding shape. Here, the molding box 304 is used to contain the slurry and provide support and a vacuum sealing environment for the molding die.

[0034] The molding die includes an upper die 307 and a lower die 306. The surfaces of both the upper die 307 and the lower die 306 are provided with mold micro-holes 308. A hydraulic telescopic rod 305 is provided between the lower die 306 and the bottom of the molding box 304. The lower die 306 is driven into the molding box 304 by the hydraulic telescopic rod 305. Then, the slurry in the molding box 304 is poured into the molding cavity formed between the upper die 307 and the lower die 306. Finally, the lower die 306 is driven to rise with the slurry by the hydraulic telescopic rod 305. The upper die 307 is connected to the drive end of the lifting mechanism.

[0035] The lifting mechanism includes a mold guide shaft 311, a drive cylinder 310, and an upper pressing module 309. The drive cylinder 310 is fixedly installed on the top of the first frame 301, with its telescopic end pointing vertically downwards. The upper pressing module 309 is fixedly connected to the telescopic end of the drive cylinder 310, and the upper mold 307 is fixedly installed at the bottom of the upper pressing module 309.

Four mold guide shafts 311 are provided and distributed at the four corners of the upper pressing module 309. The drive cylinder 310 extends downwards and drives the upper mold 307 to descend and press onto the lower mold 306 through the upper pressing module 309. Then, a vacuum adsorption system is used to generate negative pressure to remove moisture and obtain the molded blank.

[0036] The molding equipment also includes a double-sided cleaning component 400, which includes a drive mechanism, a negative pressure suction mechanism, and cleaning brushes 409. Two sets of cleaning brushes 409 are provided and are respectively arranged on the upper and lower sides of the negative pressure suction mechanism, and are used to clean the upper mold 307 and the lower mold 306 respectively. The drive mechanism is set on the first frame 301 and is used to drive the negative pressure suction mechanism to reciprocate between the upper mold 307 and the lower mold 306, so that the cleaning brushes 409 can clean the molding protrusions on the upper mold 307 and the lower mold 306, especially the fibers remaining on the mold micropores 308. At the same time, the negative pressure suction mechanism can easily suck away the cleaned fiber impurities.

[0037] In some specific implementations, the cleaning brush 409 is bristle-shaped to facilitate cleaning of micropores, and the cleaning brush 409 is made of high-temperature resistant rubber material, such as fluororubber, silicone rubber and butyl rubber.

[0038] In some specific implementations, the driving mechanism includes a first electric slide rail 404, a movable frame 405, a second electric slide rail 406, and an H-shaped support frame 407. Two sets of the first electric slide rail 404 are provided and are fixedly mounted parallel to each other on the first frame 301. The movable frame 405 is slidably mounted on the first electric slide rail 404, allowing it to reciprocate back and forth along the direction of the first electric slide rail 404. A second electric slide rail 406 is fixedly mounted on one side of the movable frame 405, and the H-shaped support frame 407 is slidably mounted on the second electric slide rail 406. The second electric slide rail 406 and the first electric slide rail 404 are perpendicular in the water surface, allowing the H-shaped support frame 407 to slide left and right on the second electric slide rail 406. One side of the H-shaped support frame 407 is connected to a negative pressure suction mechanism, thereby driving the negative pressure suction mechanism to reciprocate between the upper mold 307 and the lower mold 306.

[0039] In some specific implementations, the negative pressure suction mechanism includes an impurity collection chamber 401, a negative pressure pump 402, a delivery pipe 403, a suction box 408, and suction holes 410. The negative pressure pump 402 is fixedly mounted on the first frame 301, and its outlet is connected to the impurity collection chamber 401 to collect the suctioned impurity fibers. One end of the delivery pipe 403 is connected to the suction port of the negative pressure pump 402. The suction box 408 is fixedly connected to the H-shaped support frame 407, and the other end of the suction box 408 is connected to the delivery pipe 403. Suction holes 410 are provided on both the upper and lower sides of the suction box 408 for adsorbing the cleaned impurity fibers. Two sets of cleaning brushes 409 are connected to the upper and lower sides of the suction box 408 and are alternately distributed with the suction holes 410.

[0040] In some specific implementation schemes, the mold micro-hole 308 is a tapered hole, which adopts a tapered micro-hole structure design and uses mechanical principles to form a gradient channel. The gradual change in hole diameter reduces the probability of fiber retention in the channel.

[0041] In some specific implementations, the pulping mechanism includes a coarse crusher 100, a fine crusher 200, and a head pipe 113. The coarse crusher 100 is connected to the fine crusher 200 through the head pipe 113. The coarse crusher 100 performs primary crushing on waste paper, paperboard, or plant fiber raw materials. The crushed coarse pulp flows into the fine crusher 200 through the head pipe 113 for secondary crushing. The fine crusher 200 is equipped with a pulp inlet 210, which is connected to the forming box 304. The fine crusher 200 conveys the crushed fine pulp to the forming box 304 through the pulp inlet 210.

[0042] In some other specific embodiments, the coarse crusher 100 includes a second frame 101, a first motor 102, a first small pulley 103, a first belt 104, a first large pulley 105, a first drive shaft 106, a pinion 107, a large gear 108, a second drive shaft 109, rotating blades 111, a coarse slurry tank 110, and a coarse filter screen 112; the first motor 102 is fixedly mounted on the second frame 101, and the first small pulley 103 is fixedly mounted on the output shaft of the first motor 102.

The slurry passes through the coarse filter screen 112 to filter out the residue.

The slurry after the first filtration flows to the fine crusher 200 for fine crushing; the first drive shaft 106 is rotatably connected to one side inside the coarse slurry tank 110, and both ends protrude, and the first large pulley 105 is coaxially and fixedly connected to the first drive shaft 106; the first belt 104 is fitted between the first small pulley 103 and the first large pulley 105, the first small pulley 103 drives the first belt 104 to drive the first large pulley 105 to rotate, the first large pulley 105 drives the first drive shaft 106 to rotate, the small gear 107 is coaxially and fixedly connected to the first drive shaft 106, the first drive shaft 106 drives the small gear 107 to rotate; the second drive shaft 109 is rotatably disposed inside the coarse slurry box 110, and the large gear 108 is coaxially and fixedly connected to the first drive shaft 106. The shaft is fixedly connected to one end of the second drive shaft 109. A rotating blade 111 is fixedly installed on the second drive shaft 109, and the rotating blade 111 is positioned above the coarse filter screen 112. The position where the pulp pipe 113 communicates with the coarse pulp box 110 is lower than the position of the coarse filter screen 112. The large gear 108 meshes with the small gear 107. The small gear 107 drives the large gear 108 to rotate, and the large gear 108 drives the drive shaft to rotate, thereby driving the rotating blade 111 to rotate and crush waste paper, paperboard or plant fiber raw materials into pulp.

[0043] In some other specific embodiments, the fine crusher 200 includes a third frame 201, a second motor 202, a third drive shaft 206, fine crushing blades 207, a second small pulley 205, a second belt 204, a second large pulley 203, a fine slurry tank 209, a fine filter screen 208, and a slurry inlet 210. The second motor 202 is fixedly mounted on the third frame 201, and the second large pulley 203 is fixedly mounted on the output shaft of the second motor 202. When the second motor 202 starts, it drives the second large pulley 203 to rotate. The fine slurry tank 209 is fixedly mounted on the third frame 201, and a slurry flow pipe connects the coarse slurry tank 110 and the fine slurry tank 209. A fine filter screen 208 is installed inside the fine slurry tank 209, and the slurry passes through the fine filter screen 208 for secondary filtration of residue.

The second large pulley 203 drives the second belt 204 to drive the second small pulley 205 to rotate. The second small pulley 205 drives the third drive shaft 206 to rotate, thereby driving the fine crushing blade 207 to rotate and break the slurry after the first filtration again, so as to promote the full refinement and uniform dispersion of fibers and effectively reduce the risk of micropore blockage caused by fiber agglomeration.

[0044] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0045] The coarse crusher 100 performs primary crushing of waste paper, cardboard, or plant fiber raw materials. The crushed and filtered coarse pulp flows into the fine crusher 200 for secondary crushing through the pulp pipe 113. The crushed and filtered fine pulp is then conveyed to the forming chamber 304 through the pulp inlet 210. The upper mold 307 is connected to the drive end of the lifting mechanism. The lifting mechanism drives the upper mold 307 to descend and press it onto the lower mold 306 through the upper pressure module 309. The lower mold 306 is driven into the forming chamber 304 by the hydraulic telescopic rod 305. The pulp in the forming chamber 304 then flows into the forming cavity formed between the upper mold 307 and the lower mold 306. The lower mold 306 is then driven to rise with the pulp by the hydraulic telescopic rod 305. Then, a vacuum adsorption system is used to generate negative pressure to remove moisture, resulting in a formed blank. The mold micropores 308 are designed as tapered holes, using mechanical principles to form gradient channels and reduce the probability of fiber retention in the channels. After multiple molding processes, fiber residue may still remain on the mold surface, causing fibers or impurities to accumulate in the mold micropores 308.

[0046] Therefore, after the mold is opened and the material is taken out, the cleaning brush 409 is driven by the moving frame 405 to move back and forth along the first guide rail and driven by the H-shaped support frame 407 to move left and right along the second electric slide rail 406 to clean the forming protrusions on the upper mold 307 and the lower mold 306. In particular, for the fibers remaining on the mold micropores 308, the negative pressure pump 402 sucks them up and the impurity fibers cleaned by the cleaning brush 409 are sent to the suction box 408 through the suction hole 410. Then, the impurity fibers are transported to the impurity collection chamber 401 through the conveying pipe 403. Since the cleaning brush 409 and the suction hole 410 are both set on the upper and lower sides, the upper mold 307 and the lower mold 306 can be cleaned at the same time, improving the cleaning efficiency.

[0047] This involves the synergistic effect of three technological approaches: building an anti-clogging system at the raw material processing and mold structure levels, and installing cleaning devices between molding dies, thereby significantly improving production continuity, product yield, and overall economic benefits.

[0048] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
