Description

Technical Field

[0001] This utility model relates to the field of hygiene product manufacturing equipment technology, and in particular to a polymer feeding device with a blocking device. Background Technology

[0002] The absorbent core of disposable hygiene products is the core component that ensures the water absorption and retention function. Traditional absorbent cores are made by mixing superabsorbent polymers and wood pulp, and then covering them with wet-strength paper or hydrophilic spunbond nonwoven fabric. When adding superabsorbent polymers, it is generally necessary to use superabsorbent polymer feeding equipment to add the superabsorbent polymers onto the covering layer.

[0003] The structure of existing superabsorbent polymer (SAP) adding devices, such as the one disclosed in Chinese Patent Application No. 201820505563.X, is a SAP device for a paper composite machine. The first SAP adding device includes a storage cylinder, an adjustment component located at the output end of the storage cylinder for adjusting the amount of SAP particles fed and preventing leakage of SAP particles, and a feeding roller located at the output end of the adjustment component. The SAP in the storage cylinder is adjusted by the adjustment component to adjust the amount of SAP particles fed and prevent leakage of SAP particles, and then falls onto the feeding roller. The feeding roller spreads the SAP onto the first coating layer, thereby achieving quantitative feeding and distribution of SAP.

[0004] However, when feeding the material using the existing superabsorbent polymer additive device, it is not convenient to block the corresponding positions that need to be blocked in a timely manner according to the feeding requirements. The traditional method is to block the superabsorbent polymer material by fixing a baffle plate at the corresponding feeding port position in the storage cylinder. However, this blocking method is prone to causing the superabsorbent polymer material to be squeezed towards the baffle plate when it falls from the side of the baffle plate to the feeding roller, resulting in poor blocking effect of the baffle plate. Utility Model Content

[0005] This utility model discloses a polymer feeding device with a blocking device, which mainly solves the problem that traditional polymer water-absorbing resin adding devices are inconvenient to partially block at the feeding port and have poor blocking effect.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0007] This utility model provides a polymer feeding device with a blocking device, including a storage bin, a discharge port is provided below the storage bin, a feeding roller is provided in the storage bin corresponding to the discharge port, and at least one blocking device is provided in the discharge port.

[0008] The blocking device includes a frame and blocking blocks symmetrically arranged on the frame. One end face of the two blocking blocks is in contact with the surface of the feeding roller. An elastic element is provided between the two blocking blocks to press the two blocking blocks against the inner wall of the discharge port.

[0009] In one embodiment, the end face of the blocking block facing the feed roller is an arc-shaped surface, so that the arc-shaped surface fits against the surface of the feed roller.

[0010] In one embodiment, the frame includes a horizontal plate, with support plates symmetrically arranged at both ends of the horizontal plate facing the discharge port, and two blocking blocks disposed between the two support plates.

[0011] In one embodiment, a limiting plate is provided on the side of the support plate facing the blocking block, and a limiting groove is provided on the blocking block at the position corresponding to the limiting plate, with the limiting plate embedded in the limiting groove.

[0012] In one embodiment, the blocking block is provided with a recessed positioning groove at the position corresponding to the elastic element, and the end of the elastic element is embedded in the positioning groove.

[0013] In one embodiment, multiple elastic elements are provided, and the multiple elastic elements are evenly distributed between two blocking blocks.

[0014] The advantages or beneficial effects of the above technical solution include at least the following: when the polymer material in the storage bin is discharged to the discharge roller through the discharge port, the blocking device is set up so that the blocking block is installed at the discharge port by the frame of the blocking device, and with the cooperation of the two blocking blocks and the elastic element, the corresponding position of the discharge port can be blocked. After the blocking block blocks the discharge roller, the polymer material can be prevented from being discharged to the corresponding position on the discharge roller through the discharge port, so as to ensure the blocking effect. At the same time, the cooperation of the frame, blocking block and elastic element can facilitate the quick installation at the discharge port. Attached Figure Description

[0031] See Figures 1 to 4 The present invention provides a polymer feeding device with a blocking device, including a storage bin 1, a discharge port 11 is provided below the storage bin 1, a feeding roller 2 is provided in the storage bin 1 corresponding to the position of the discharge port 11, and at least one blocking device 3 is provided in the discharge port 11.

[0032] The blocking device 3 includes a frame 31 and blocking blocks 32 symmetrically arranged on the frame 31. One end face of the two blocking blocks 32 is in contact with the surface of the feed roller 2. An elastic element 33 is provided between the two blocking blocks 32 to press the two blocking blocks 32 against the inner wall of the discharge port 11. The elastic element 33 can be a spring.

[0033] With the above structure, when the polymer material in the storage bin 1 is discharged to the discharge port 11 onto the discharge roller 2, the blocking device 3 is used. The frame 31 of the blocking device 3 installs the blocking block 32 at the discharge port 11. With the cooperation of the two blocking blocks 32 and the elastic member 33, the corresponding position of the discharge port 11 can be blocked. After the blocking block 32 blocks the discharge roller 2, the polymer material can be prevented from being discharged from the discharge port 11 onto the corresponding position of the discharge roller 2, so as to ensure the blocking effect. At the same time, with the cooperation of the frame 31, the blocking block 32 and the elastic member 33, it is easy to quickly install it at the discharge port 11.

[0034] In one embodiment, see Figure 3 and Figure 4 The end face of the blocking block 32 facing the feeding roller 2 is an arc-shaped surface 321, which fits against the surface of the feeding roller 2. In practical applications, the arc-shaped surface 321, in cooperation with the feeding roller 2, can block the feeding roller 2 at the position corresponding to the discharge port 11, thereby preventing polymer materials from entering the feeding roller 2 and ensuring the blocking effect.

[0035] In one embodiment, see Figure 4 The frame 31 includes a horizontal plate 311, with support plates 312 symmetrically arranged at both ends of the horizontal plate 311 facing the discharge port 11. Two blocking blocks 32 are disposed between the two support plates 312. In practical applications, the blocking blocks 32 can be confined between the two support plates 312 through the cooperation of the horizontal plate 311 and the support plates 312.

[0036] A limiting plate 313 is provided on the side of the support plate 312 facing the blocking block 32, and a limiting groove 322 is provided on the blocking block 32 corresponding to the position of the limiting plate 313, with the limiting plate 313 embedded in the limiting groove 322. In practical applications, the movement direction of the blocking block 32 between the two support plates 312 can be restricted through the cooperation of the limiting plate 313 and the limiting groove 322.

[0037] In one embodiment, see Figure 3 and Figure 4 The blocking block 32 has a recessed positioning groove 323 corresponding to the position of the elastic member 33, and the end of the elastic member 33 is embedded in the positioning groove 323. In practical applications, the positioning groove 323 can be used to position the end of the elastic member 33.

[0038] Multiple elastic elements 33 are provided, and the multiple elastic elements 33 are evenly distributed between the two blocking blocks 32. Among them, three elastic elements 33 can be provided and evenly distributed between the two blocking blocks 32; in practical applications, multiple elastic elements 33 are provided and evenly distributed to ensure that the elastic force of each part of the two blocking blocks 32 is uniform.
