Description

Technical Field

[0001] The invention relates to the technical field of filter paper production, and in particular to a filter paper oblique mark folding machine. Background Art

[0002] In the production process of the filter device, the filtering effect of the filter element directly determines the overall performance of the equipment. Among them, paper filter elements are widely used in air and water filtration systems due to their low cost and moderate filtering efficiency. However, in order to improve the filtering performance of paper filter elements, increasing the contact area between the filter paper and the air or water is the key. Therefore, when producing paper filter elements, a flat filter paper needs to be folded into a corrugated or multi-layer structure in a specific way to form more filtering layers.

[0003] Most of the existing filter paper folding devices are vertically folded, forming a paper folding mechanism similar to a cutter. The paper folding knife keeps flipping up and down to fold the continuously conveyed filter paper. However, in this case, the filter paper can only be folded once each time, the folding speed is slow, and the overall folding range of the folding machine depends on the size of the machine. A larger folding machine requires a larger hydraulic up and down moving mechanism, and the overall cost is also high. Therefore, a filter paper oblique mark folding machine is proposed. Summary of the invention

[0004] The object of the present invention is to provide a filter paper oblique mark folding machine to solve the problems raised in the above background technology.

The inner supporting annular cutting plate with a V-shaped cross-section and a bottom opening end with a thickness greater than the top pointed end is used to expand the external expansion bladder when gas is filled into the external expansion bladder. When the external expansion bladder expands, the inner supporting annular cutting plate will gradually slide inside the sliding groove due to the expansion of the external expansion bladder. When the external expansion bladder expands to a specified degree, the inner supporting annular cutting plate whose bottom opening end is thicker than the top pointed end will close the sliding groove, thereby forming a closed space inside the external expansion bladder to avoid continuous leakage of air inside the external expansion bladder.

During the continuous transmission process of the filter paper, the filter paper can be folded multiple times at one time to increase the oblique folding speed of the filter paper.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Figure 1 As shown, the present application is a filter paper oblique mark folding machine, including a bottom support plate 100, to which a plurality of strip extrusion groove plates 101 are fixedly connected, the strip extrusion groove plates 101 are divided into a feed end and a discharge end, a plurality of pairs of limiting vertical plates are fixedly connected to the bottom support plate 100, a rolling groove is provided on the limiting vertical plate, a roller 102 is rotatably connected inside the rolling groove, a support rod 103 is fixedly connected inside the roller 102, and an extrusion roller 104 is fixedly connected outside the support rod 103.

[0030] Specifically, during use, the staff places the filter paper on the bottom support plate 100 and the strip extrusion slot plate 101. As the front and rear ends of the filter paper are continuously rolled up and transported, the filter paper can be driven to move on the strip extrusion slot plate 101. A belt drive mechanism is connected to one end of the plurality of rollers 102 away from the direct current tube 109. The belt drive mechanism actively rotates the rollers 102 and the support rods 103 through a motor and a belt, thereby assisting the filter paper in being transported and moved on the strip extrusion slot plate 101. During the transmission and movement of the filter paper, the extrusion rollers 104 will cooperate with the strip extrusion groove plate 101 to extrude the filter paper during the transmission process. When the extrusion roller 104 is rotating and contacting the filter paper, the filter paper is squeezed by the pointed end of the external roller to form an indentation. At the same time, when the filter paper enters the strip extrusion groove plate 101, under the extrusion of the extrusion roller 104, the filter paper will fall into the gap formed between the multiple strip extrusion groove plates 101. After the filter paper falls into the gap formed by the multiple strip extrusion groove plates 101, the filter paper can be extruded and formed by cooperating with the pointed end of the outside of the extrusion roller 104 to be squeezed into a folded shape.

[0031] Furthermore, the strip-shaped extrusion slot plates 101 are arranged gradually in a conical shape from the feed end to the discharge end.

[0032] Specifically, the multiple strip-shaped extrusion slots 101 are gradually arranged in a cone shape from the feed end to the discharge end and can gradually shrink and extrude the folded filter paper inward during the process of continuously transmitting the folded filter paper, thereby further shrinking the folding angle of the folded filter paper and further squeezing the folded filter paper together to form a tighter folded state, further stabilizing the folded shape of the filter paper.

[0033] like Figure 1 As shown, a tightening plate 600 is connected to one side of the bottom support plate 100 close to the discharge end of the strip extrusion slot plate 101 , and a shaping and pulling assembly 601 is installed on the tightening plate 600 .

[0034] Specifically, the folded filter paper is further shaped and tightened through the setting of the tightening plate 600, and after the tightening plate 600 continuously shapes and tightens the filter paper, the folded and tightened filter paper is further continuously heated, tightened and transmitted through the rear shaping and pulling component 601. A driving motor is installed on the shaping and pulling component 601, and the filter paper is continuously transmitted through the driving motor. At the same time, when the filter paper is heated, transmitted and tightened to a certain section, it is cut off to complete the processing of the filter paper.

[0035] like Figure 1-Figure 3As shown, the interior of the extrusion roller 104 is integrally formed with a plurality of expansion capsules 111, the interior of the support rod 103 is rotatably connected to a rotating connector 108, the rotating air inlet of the rotating connector 108 is connected to a direct current tube 109, the end of the direct current tube 109 away from the rotating connector 108 is connected to a side diversion conveying box 106, the outside of the side diversion conveying box 106 is connected to a plurality of bidirectional air pumps 105, the rotating air outlet of the rotating connector 108 is connected to an inner conveying pipe 107, the outside of the inner conveying pipe 107 is connected to an electrically controlled multi-head diversion valve 110, and the air outlet of the electrically controlled multi-head diversion valve 110 is connected to the expansion capsule 111.

[0036] Specifically, during use, when the filter paper needs to be folded into shapes with different spacings, the staff can start the two-way air pump 105 and continuously inject gas into the side shunt delivery box 106 through the two-way air pump 105. When the gas is continuously injected into the side shunt delivery box 106, the side shunt delivery box 106 will shunt the gas and shunt the gas into multiple direct current tubes 109. During the continuous gas delivery process, the gas delivery channel of the rotary connector 108 is opened. After the gas delivery channel is opened, the gas will enter the interior of the inner delivery tube 107. When the gas enters the interior of the inner delivery tube 107, Under the condition that one or more electrically-controlled multi-head diverter valves 110 are opened again, after the electrically-controlled multi-head diverter valves 110 are opened, the gas will be delivered to the interior of the expansion capsule 111 through the inner delivery pipe 107 and the electrically-controlled multi-head diverter valve 110, and when the gas is delivered to the interior of the expansion capsule 111, the expansion capsule 111 will expand due to the continuous entry of the gas. When the gas drives the expansion capsule 111 to continue to expand, the distance between the pointed ends of the extrusion rollers 104 can be increased. When the distance between the pointed ends of the extrusion rollers 104 gradually increases, the distance between the folds of the filter paper can be increased, thereby completing the production of filter paper with different fold distances.

[0037] like Figure 1 As shown, two groups of fixed frames are fixedly connected to the bottom support plate 100, and the first material guiding and forming roller 700 is rotatably connected to the two groups of fixed frames. The sliding plate 701 is slidably connected to the two groups of fixed frames, and the second material guiding and forming roller 702 is rotatably connected inside the sliding plate 701. An adjusting screw is threadedly connected to the fixed frame, and the bottom of the adjusting screw is rotatably connected to the sliding plate 701. One end of the first material guiding and forming roller 700 and the second material guiding and forming roller 702 are fixedly connected with gears, and the gears connected to the first material guiding and forming roller 700 and the second material guiding and forming roller 702 are meshed with each other.

[0038] Specifically, during use, the first material guiding and forming roller 700 and the second material guiding and forming roller 702 can be driven to rotate by starting the driving structure. During the rotation, the filter paper in the folding process can be transmitted. At the same time, during the transmission process, the user can adjust the distance between the first material guiding and forming roller 700 and the second material guiding and forming roller 702 according to the situation. When it is necessary to adjust the distance between the first material guiding and forming roller 700 and the second material guiding and forming roller 702, the adjusting screw on the rotating fixed frame can be used to drive the sliding plate 701 to move up and down on the fixed frame, thereby adjusting the distance between the first material guiding and forming roller 700 and the second material guiding and forming roller 702.

[0039] like Figure 9-10 As shown, multiple telescopic sacs 500 are connected between multiple strip extrusion groove plates 101, a lower shunt conveying box 501 is installed at the bottom of the bottom support plate 100, the air inlet of the telescopic sac 500 passes through the outer wall of the bottom support plate 100 and is connected to the lower shunt conveying box 501, the air inlet and outlet of the lower shunt conveying box 501 are connected to a secondary regulating pipe, and the end of the secondary regulating pipe away from the lower shunt conveying box 501 is connected to the two-way air pump 105.

[0040] Specifically, during use, when it is necessary to adjust the spacing of the filter paper folds, the two-way air pump 105 can be started to inject gas into the secondary regulating tube and the lower shunt conveying box 501. In the process of injecting gas into the secondary regulating tube and the lower shunt conveying box 501, the gas is gradually transported to the interior of the telescopic sac 500 through the lower shunt conveying box 501. When gas is injected, the interior of the telescopic sac 500 can gradually push the multiple strip extrusion slot plates 101 to separate from each other, thereby increasing the spacing between the multiple strip extrusion slot plates 101, thereby adapting to the increase in the spacing between the extrusion rollers 104.

[0041] like Figure 1 As shown, a plurality of mounting frames 800 are fixedly connected to the bottom support plate 100 , and a pressing plate 801 is movably connected to the outside of the mounting frames 800 .

[0042] Specifically, during use, the pressing plate 801 is installed through the mounting frame 800 to prevent the other end of the filter paper from tilting and being misplaced when the filter paper is squeezed.

[0043] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, the filter paper can be folded obliquely laterally through the arrangement of the strip extrusion groove plate 101 and multiple extrusion rollers 104, and during the continuous transmission of the filter paper, the filter paper can be folded multiple times at one time to increase the oblique folding speed of the filter paper, and during the folding process, the staff can start the two-way air pump 105 to continuously deliver gas to the interior of the expansion capsule 111 according to the folding requirements of the filter paper, so that the expansion capsule 111 drives the indentation sharp end of the extrusion roller 104 to separate, thereby increasing the spacing of the indentation folds to meet the folding requirements of different filter papers.

[0044] Embodiment 2: Considering that during use, although the distance between the filter paper folds can be increased by expanding the capsule 111 and the number of filter paper folds can be reduced, the number of filter paper folds may be increased under different filter paper usage conditions. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0045] like Figure 4-Figure 5 As shown, the outside of the squeezing roller 104 is integrally formed with an external expansion bladder 200, and the air outlet port of the electrically controlled multi-head diverter valve 110 is a three-head port, one of the air outlet ends is connected to the expansion bladder 111, and the air outlet port of the other electrically controlled multi-head diverter valve 110 is connected to a hose, and the end of the hose away from the electrically controlled multi-head diverter valve 110 passes through the outer wall of the squeezing roller 104 and is connected to the external expansion bladder 200.

[0046] Specifically, during use, when it is necessary to increase the number of filter paper folds, the staff can open the two air outlet ports of the electrically controlled multi-head diverter valve 110 to respectively deliver the gas to the interior of the expansion bladder 111 and the external expansion bladder 200. When the gas is respectively delivered to the interior of the expansion bladder 111 and the external expansion bladder 200, both the expansion bladder 111 and the external expansion bladder 200 will continue to expand. During the continuous expansion, the external expansion bladder 200 will form a new extrusion folding roller. After the new extrusion folding roller is formed, a more intensive folding process of the folded paper can be achieved.

[0047] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment 1, in the present embodiment, the gas filled into the expansion bladder 111 is diverted to the outside expansion bladder 200 through the electrically controlled multi-head diverter valve 110, and the gas causes the outside expansion bladder 200 to expand after entering the outside expansion bladder 200. When the outside expansion bladder 200 expands, a new extrusion and folding roller is formed, so that the folded paper is more densely extruded and folded during the continuous transmission of the folded paper to meet the folding quantity requirements of different filter papers.

[0048] Embodiment 3: Considering that the external expansion bladder 200 is supported by gas during use, when gas is used for support, the material of the external expansion bladder 200 is relatively soft, and a relatively clear crease may not be formed well during the process of squeezing the filter paper. At the same time, when the external expansion bladder 200 is supported by gas, the external expansion bladder 200 will expand excessively outwards due to the continuous entry of gas, which may easily lead to the crease being too large or too small. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0049] like Figure 6-Figure 7 As shown, the inner wall of the outer expansion bladder 200 is integrally formed with an inner supporting annular cutting plate 300 , the outer wall of the squeezing roller 104 is provided with a sliding groove 301 , and the inner supporting annular cutting plate 300 is slidably connected to the inside of the sliding groove 301 .

[0050] Specifically, during use, when gas is continuously injected into the outer expansion bladder 200 through the electrically controlled multi-head diverter valve 110, the outer expansion bladder 200 will gradually expand. During the gradual expansion process, the outer expansion bladder 200 will drive the inner supporting annular cutting plate 300 to move. When the outer expansion bladder 200 expands to a specified angle, the inner supporting annular cutting plate 300 can support the outer expansion bladder 200, thereby increasing the squeezing force of the outer expansion bladder 200 on the filter paper and avoiding excessive deformation of the outer expansion bladder 200 due to its own elasticity when squeezing the filter paper.

[0051] Furthermore, the inner supporting annular cutting plate 300 is annular as a whole, and the cross-section of the inner supporting annular cutting plate 300 is V-shaped. The thickness of the bottom opening end of the inner supporting annular cutting plate 300 with a V-shaped cross-section is greater than the top pointed end. The inner supporting annular cutting plate 300 with a V-shaped cross-section and a bottom opening end with a thickness greater than the top pointed end is used to expand the outer expansion bladder 200 when gas is filled into the outer expansion bladder 200. When the outer expansion bladder 200 expands, the inner supporting annular cutting plate 300 will gradually slide inside the sliding groove 301 due to the expansion of the outer expansion bladder 200, and when the outer expansion bladder 200 expands to a specified degree, the inner supporting annular cutting plate 300 with a bottom opening end with a thickness greater than the top pointed end will close the sliding groove 301, thereby forming a closed space inside the outer expansion bladder 200 to prevent continuous leakage of air inside the outer expansion bladder 200.

[0052] Furthermore, after use is completed, the two-way air pump 105 can be started in reverse and the gas inside the external expansion bladder 200 can be extracted through the electrically controlled multi-head diverter valve 110 and the internal delivery pipe 107. When the gas inside the external expansion bladder 200 is continuously extracted, the external expansion bladder 200 will produce condensation. When the external expansion bladder 200 continues to produce condensation, the inner supporting annular cutting plate 300 can be pulled in reverse to move out of the sliding groove 301, and the clamping of the sliding groove 301 to the inner supporting annular cutting plate 300 can be cancelled. At the same time, when the inner supporting annular cutting plate 300 continues to slide inward, it can pass through the sliding groove 301 parallel to the interior of the expansion bladder 111 and be stored in the interior of the expansion bladder 111.

[0053] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: during use, when the inner supporting annular cutting plate 300 moves when the inflated outer expansion bladder 200 is in use, the position where the thickness of the open end of the inner supporting annular cutting plate 300 is larger will block the sliding groove 301, and when gas continues to enter, the higher the blocking degree will be, and in the case of a continuous gap, the inner supporting annular cutting plate 300 can also be temporarily clamped and positioned, so that when the inner supporting annular cutting plate 300 drives the outer expansion bladder 200 to squeeze and fold the filter paper, clear creases can be formed more stably, and at the same time, when the outer expansion bladder 200 is temporarily positioned, the inner supporting annular cutting plate 300 can drive the outer expansion bladder 200 to expand only to a specified degree, avoiding the situation where the crease is too large or too small.

[0054] Embodiment 4: Considering that during use, the opening and closing angle of the inner supporting annular cutting plate 300 is determined by the amount of gas entering the outer expansion bladder 200, when the amount of gas inside the outer expansion bladder 200 reaches a certain level, it is necessary to stop injecting gas into the outer expansion bladder 200 to avoid excessive expansion of the outer expansion bladder 200. When the gas stops entering the outer expansion bladder 200, the V-shaped angle between the inner supporting annular cutting plates 300 cannot be opened to the specified angle, and the filter paper cannot be squeezed into the specified shape. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0055] like Figure 6-Figure 8 As shown, a plurality of elastic support bags 400 are integrally formed inside the V-shaped opening of the inner supporting annular cutting plate 300 , and a connecting pipe 401 is connected to the outside of the elastic support bag 400 , and the connecting pipe 401 is connected to the third air outlet port of the electric-controlled multi-head diverter valve 110 .

[0056] Specifically, during use, when the outer expansion bladder 200 expands to a specified degree and the inner supporting annular cutting plate 300 has not yet opened to a specified angle, the third gas outlet port of the electrically controlled multi-head diverter valve 110 can be opened, and the gas can be continuously delivered to the interior of the connecting tube 401. After the gas is continuously delivered to the interior of the connecting tube 401, it will be diverted to multiple elastic support bladders 400 through the connecting tube 401. When the gas is diverted to the elastic support bladder 400, the elastic support bladder 400 will expand. When the elastic support bladder 400 gradually expands, the V-shaped opening of the inner supporting annular cutting plate 300 can be driven to gradually expand, thereby gradually squeezing the outer expansion bladder 200 through the inner supporting annular cutting plate 300, so that the expanded outer expansion bladder 200 forms a specified angle, thereby squeezing the filter paper into a specified shape.

[0057] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment three, in this embodiment, when the outer expansion bladder 200 expands to a specified degree, gas is continuously transported to the interior of multiple elastic support bladders 400 through the connecting tube 401. The interior of the elastic support bladder 400 will produce lateral expansion when gas continues to enter. When the elastic support bladder 400 produces lateral expansion, the V-shaped opening of the inner support annular cutting plate 300 can be pushed to expand, so that the inner support annular cutting plate 300 drives the outer expansion bladder 200 to form a specified extrusion shape, so that the outer expansion bladder 200 can extrude the filter paper into a specified shape, avoiding the phenomenon of extrusion and folding errors.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
