Description

Technical Field

[0001] This utility model relates to the field of fiber processing technology, and in particular to a fiber combing and web forming device. Background Technology

[0002] Forming wire is an important piece of equipment on a paper machine. It is a device for forming and dewatering paper sheets. It dewaters the pulp suspension from the headbox and carries the paper web to subsequent stages. Forming wire can be produced using a variety of materials. Currently, the materials commonly used in the production of high-precision fiber forming wire require the fibers to be combed beforehand during the production process of forming wire.

[0003] For example, Chinese Patent Publication No. CN208362546U discloses a high-precision fiber combing device for producing shaped mesh, which includes a base. The upper surface of the base is provided with a second base and a first base that are opposite to each other and parallel to each other.

The left side between the first base and the second base is provided with a mounting plate, and the upper surface of the mounting plate is provided with a strip comb. The right side between the first base and the second base is provided with three rotating shafts that are located on the same horizontal line and parallel to each other. A main roller is fixed on the middle rotating shaft. This utility model has a simple structure and is easy to use. It can comb out the possible entanglement of the high-precision fibers used in the production of shaped mesh before pressing and uniformly combing them, thereby reducing the disorder of the high-precision fibers.

[0004] The above application still has shortcomings. The carding combs in the above application are difficult to replace and are not suitable for different fiber treatments, which affects the overall processing continuity. At the same time, the carding combs are difficult to remove for cleaning, which affects the convenience of cleaning and maintenance.

[0005] Therefore, it is necessary to provide a fiber combing and web forming device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a fiber combing and web forming device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A fiber carding and web forming device includes a housing, inside which a column roller is disposed. An end rod is fixed to one end of the column roller and is rotatably connected to the side wall of the housing. T-shaped grooves are formed on the side of the column roller along its length. Multiple T-shaped grooves are arranged in a ring. Carding strips are inserted into the T-shaped grooves. Multiple equidistant comb teeth are fixed on the carding strips. The comb tooth density is different on different carding strips. A limiting component is provided at one end of the column roller to limit the positioning of the carding strips inserted in the T-shaped grooves. An insertion component is provided outside the end rod to lock the column roller.

[0008] As a further embodiment of this utility model, the insertion assembly includes an outer sleeve fixed to the outer wall of the housing and sleeved outside the end rod. An insertion rod slides through the side wall of the outer sleeve. An insertion hole that matches the inner end of the insertion rod is opened on the side of the end rod. Multiple insertion holes are provided and are arranged in a ring. The multiple insertion holes correspond to multiple combing strips.

[0009] As a further embodiment of this utility model, an end plate is fixed to the outer end of the insertion rod, and a spring is sleeved on the side of the insertion rod, with the two ends of the spring respectively fixed to the side of the end plate and the outer wall of the outer sleeve.

[0010] As a further embodiment of this utility model, the stop assembly includes a shaft fixed to the side of the roller end, and multiple shafts are provided, with each shaft corresponding to a multiple T-shaped groove. Each of the multiple shafts is rotatably connected to an external plate that stops the combing strip inserted in the T-shaped groove.

[0011] As a further embodiment of this utility model, a rubber pad is attached and fixed to the inner side of the outer plate near the T-shaped groove.

[0012] As a further embodiment of this utility model, a handle rod is fixed to the end of the end rod away from the roller, and a rubber sleeve is fitted onto the surface of the handle rod.

[0013] As a further embodiment of this utility model, the inner end of the insertion rod is provided with an arc-shaped end.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When different fibers need to be combed, the locking component can be used to release the column roller, allowing the column roller to be rotated and adjusted. Then, the locking component can be used to relock the column roller, allowing different combing strips to be switched to comb the fibers.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1-6This utility model provides a fiber carding and web forming device, including a housing 4. A roller 3 is disposed inside the housing 4. An end rod 8 is fixed to one end of the roller 3 and is rotatably connected to the side wall of the housing 4. T-shaped grooves 7 are formed on the side of the roller 3 along its length. Multiple T-shaped grooves 7 are arranged in a ring. Carding strips 6 are inserted into the T-shaped grooves 7. Multiple equidistant comb teeth 5 are fixed on the carding strips 6, with different comb tooth densities on different carding strips 6. A stop component 2 is provided at one end of the roller 3 to limit the carding strips 6 inserted in the T-shaped grooves 7. An insertion component 1 is provided outside the end rod 8 to lock the roller 3. In use, multiple carding strips 6 are inserted into multiple T-shaped grooves 7, and the stop component 2 stops and limits the carding strips 6 inserted in the T-shaped grooves 7. Before pressing and uniformly carding the high-precision fibers used to produce the web, the fibers are carded from the comb teeth on the carding strips 6. The comb 5 passes through the teeth evenly, thus combing the high-precision fibers used in the production of the formed web before pressing and evenly combing them. This reduces the disorder of the high-precision fibers and ensures the production quality of the formed web. When different fibers need to be combed, the locking component 1 releases the lock of the roller 3, allowing the roller 3 to be rotated and adjusted. The locking component 1 then relocks the roller 3, allowing different combing bars 6 to be used to comb the fibers. This enables rapid adaptation to different fibers and precise matching based on fiber characteristics. The fine-pitch comb is used for fine cotton fibers, further improving combing uniformity. New fiber combing work can be started quickly, improving production continuity. When the comb teeth 5 on the comb bar 6 need to be cleaned, the limiting component 2 can quickly release the limit on the comb bar 6, allowing it to be easily pulled out of the T-groove 7 for cleaning and maintenance, improving maintenance convenience.

[0028] Further as Figure 2 , Figure 3 and Figure 6As shown, it is worth noting that the insertion assembly 1 includes an outer sleeve 101 fixed to the outer wall of the housing 4 and sleeved outside the end rod 8. An insertion rod 104 slides through the side wall of the outer sleeve 101. An insertion hole 106 is provided on the side of the end rod 8 to match the inner end of the insertion rod 104. Multiple insertion holes 106 are provided and are arranged in a ring. The multiple insertion holes 106 correspond to multiple carding strips 6. When different fibers need to be carded, the end of the insertion rod 104 is pulled out from the insertion hole 106 to release the locking of the roller 3, thereby allowing the roller 3 to be rotated and adjusted. Then, the insertion rod 104 is reinserted into different insertion holes 106 to relock the roller 3. This allows for switching between different carding strips 6 to card the fibers, enabling rapid adaptation to different fibers. It can accurately adapt to fiber characteristics. The fine-pitch carding comb is used for fine cotton fibers to further improve carding uniformity. New fiber carding work can be quickly started, improving production continuity.

[0029] Further as Figure 2 As shown, it is worth noting that an end plate 102 is fixed on the outer end of the insertion rod 104, and a spring 103 is sleeved on the side of the insertion rod 104. The two ends of the spring 103 are fixed to the side of the end plate 102 and the outer wall of the outer sleeve 101, respectively. In actual operation, the spring 103 pulls the inner end of the insertion rod 104 to stably insert it into the insertion hole 106, thereby improving the stability of the roller 3 during operation.

[0030] Further as Figure 3 and Figure 4 As shown, it is worth noting that the stop assembly 2 includes a shaft 202 fixed to the side of the end of the roller 3. Multiple shafts 202 are provided, and each shaft 202 corresponds to a multiple T-slot 7. Each shaft 202 is rotatably connected to an outer plate 201 that stops the combing strip 6 inserted in the T-slot 7. In actual operation, by rotating and adjusting the outer plate 201, the combing strip 6 is stopped and limited by the outer plate 201. When the comb teeth 5 on the combing strip 6 need to be cleaned, the combing strip 6 can be easily pulled out and removed from the T-slot 7 by rotating the outer plate 201 away from the combing strip 6, which facilitates cleaning and maintenance and improves maintenance convenience.

[0031] This solution has the following working process: Before pressing and uniformly combing the high-precision fibers used in the production of the formed mesh, the fibers pass through the comb teeth 5 on the combing strip 6 in strips evenly. Thus, before pressing and uniformly combing the high-precision fibers used in the production of the formed mesh, the combing strip 6 combs the high-precision fibers, reducing the disorder of the high-precision fibers and ensuring the production quality of the formed mesh. When different fibers need to be combed, the end of the insertion rod 104 is pulled out from the insertion hole 106 to release the lock of the column roller 3, so that the column roller 3 can be rotated and adjusted. Then, the insertion rod 104 is reinserted into different insertion holes 106, so that the column roller 3 is relocked. Thus, different combing strips 6 can be switched to comb the fibers, so as to quickly adapt to combing different fibers. When the comb teeth 5 on the combing strip 6 need to be cleaned, the outer plate 201 is rotated away from the combing strip 6, so that the combing strip 6 can be easily pulled out from the T-groove 7 for cleaning and maintenance.

[0032] Further as Figure 4 As shown, it is worth noting that a rubber pad 203 is attached and fixed to the inner side of the outer plate 201 near the T-groove 7; during operation, the rubber pad 203 increases the contact friction between the outer plate 201 and the end side wall of the roller 3.

[0033] Further as Figure 3 As shown, it is worth noting that a handle rod 9 is fixed on the end of the end rod 8 away from the column roller 3, and a rubber sleeve 10 is fitted onto the surface of the handle rod 9; in actual operation, the column roller 3 can be easily rotated and adjusted by the handle rod 9, which is convenient for operation.

[0034] Further as Figure 6 As shown, it is worth noting that the inner end of the insertion rod 104 is provided with an arc-shaped end 105.

[0035] In summary: When different fibers need to be combed, the locking component 1 releases the lock of the roller 3, allowing the roller 3 to be rotated and adjusted. The locking component 1 then relocks the roller 3, enabling the switching of different combing strips 6 to comb the fibers. This allows for rapid adaptation to different fibers and precise matching based on fiber characteristics. The fine-pitch comb is used for fine cotton fibers, further improving combing uniformity. New fiber combing can be started quickly, improving production continuity. When the comb teeth 5 on the combing strip 6 need cleaning, the limiting component 2 can quickly release the limit on the combing strip 6, allowing it to be easily pulled out of the T-groove 7 for cleaning and maintenance, improving maintenance convenience.
