Description

Technical Field

[0001] The invention relates to the technical field of filtering product production equipment, in particular to a highly efficient enveloping device and a working method thereof. Background Art

[0002] In production practice, when filter materials need to be configured, it is usually necessary to arrange the filter materials along a circular path to separate the space, forming an unfiltered cavity and a filtered cavity, such as Figure 1 In the prior art, in order to maximize the filtration area within a limited space, the filter material is usually folded in a W shape or other folded shapes. The folded filter material has poor support in the width direction. When workers arrange the filter material, it is easy to cause uneven arrangement or even overlap of the filter material. In addition, when the filter material is large in width, it often requires the cooperation of multiple people to complete it, which is time-consuming and labor-intensive, and the quality of the finished product is uneven. Summary of the invention

The technical solution adopted is as follows:

[0004] An efficient enclosing device includes a first component and a second component, wherein the first component forms a first hollow cavity with an inner diameter of A1, and the second component forms a second hollow cavity with an inner diameter of A2. The second component and the first component can be moved closer or farther away from each other under the action of an external first driving unit to enclose materials stored in the first hollow cavity and the second hollow cavity.

[0005] On the basis of the above technical solution, it also includes a third component, the third component forms a third hollow cavity with an inner diameter of A3, and the A3 is larger than A1 and smaller than A2, and the first component, the third component and the second component are arranged in sequence up and down.

[0006] On the basis of the above technical solution, it also includes a vertical plate, a first guide shaft and a second guide shaft, the first component is fixed with a first arm, the second component is fixed with a second arm, the third component is fixed with a third arm, the ends of the first arm, the second arm and the third arm are all slidably connected to the vertical plate; the first guide shaft is fixed with the third arm upward and passes through the first arm downward to be slidably connected to the first arm upward, and the lower end of the first guide shaft extending out of the first arm is fixed with a first retaining ring; the second guide shaft is fixed with the second arm upward and passes through the third arm downward to be slidably connected to the third arm upward, and the lower end of the second guide shaft extending out of the third arm is fixed with a second retaining ring, and the first driving unit is fixed on the vertical plate and can drive the second arm to move up and down. Preferably, when the third component and the second component reach the upper limit relative to the first component, the first component, the second component and the third component jointly enclose to form a conical cavity.

[0007] On the basis of the above technical solution, the outer wall surfaces of the first component and the second component that abut against the material are arc surfaces.

[0008] On the basis of the above technical solution, it also includes a fixed core mold, which is sleeved in the first component and the second component, and the core mold is coaxially arranged with the first component and the second component, and a containment cavity for accommodating materials is formed between the first component and the core mold, and between the second component and the core mold.

[0009] Based on the above technical solution, the core mold is larger at the top and smaller at the bottom and is conical.

[0010] On the basis of the above technical solution, it also includes an ejection unit, which includes a plurality of push arms. The push arms can be displaced under the action of an external second driving unit. When the push arms abut against the end faces of the wrapped materials and displace, the wrapped materials can pass through the first hollow cavity with a smaller inner diameter to further wrap the materials.

[0011] On the basis of the above technical solution, the pushing unit also includes a mounting seat fixed in the core mold and a swing arm arranged one-to-one with the push arm. The push arm is slidably connected to the outer wall of the mounting seat up and down. The first end of the push arm can pass through the first through hole on the core mold and extend out of the core mold. The second end of the push arm passes through the mounting seat and is hinged to the first end of the swing arm. The second end of the swing arm is hinged to the movable seat.

[0012] On the basis of the above technical solution, it also includes a pallet, the outer edge of the pallet includes a fence, and the fence is configured so that when the material is placed on the pallet and laterally abuts against the fence, the material is coaxial with the first component and the second component; the pallet is also provided with a drop opening corresponding to the position of the first component.

[0013] A working method of a wrapping device, using the wrapping device as described above, comprises the following steps:

[0014] placing a material horizontally above the first member and the second member;

[0015] The first member and the second member are switched from a close state to a separated state under the action of an external first driving unit to wrap the material;

[0016] The wrapped material escapes from the first component and the second component, and the first component and the second component are restored from a separated state to a close state under the action of an external first driving unit.

[0017] Beneficial Effects

[0018] The present invention is ingenious and includes a first component and a second component. When the first component and the second component are separated from each other, the horizontally placed material is wrapped toward the center and vertically straightened under the support of the first component and the second component, thereby replacing manual wrapping and having high operating efficiency. During the wrapping process, the material is subjected to more uniform force, so that the uniformity after wrapping is good, which is beneficial to improving the quality of the finished product.

[0019] In the present invention, in order to improve the good support of the material during the wrapping process, a third component, or even a fourth and fifth component, may be included to stably support the material and prevent the material from slipping out of the component or bulging outward during the wrapping process, which is conducive to ensuring stable and continuous production. In addition, the inner diameter values ​​of the components arranged in sequence up and down are gradually changed. On the one hand, during the wrapping process, the material can be gradually and hierarchically wrapped toward the center, which is further conducive to the smooth progress of the wrapping operation. On the other hand, the component with a smaller inner diameter can be closer to the set outer diameter size of the material after wrapping, thereby improving the wrapping quality. The design is ingenious. In the present invention, multiple components act in conjunction, which not only simplifies the structure, but also ensures the position accuracy between multiple components. The design is ingenious.

[0020] The present invention is reasonably designed and also includes a core mold. A wrapping cavity is formed between the core mold and a plurality of components. When wrapping, the material is stored in the wrapping cavity so that both sides of the material are supported by force, thus further ensuring the smooth progress of the wrapping process; the present invention is ingenious and also includes a pushing unit. The material that is conical after wrapping passes through the component with the smallest inner diameter under the pushing action of the pushing unit. This process can further shrink the conical material into a cylindrical shape, thus completing the wrapping of the material and allowing the material to escape to enter the next production process, facilitating the connection of the process. In addition, the arrangement of a plurality of push arms in the pushing unit allows the push arms to adjust the coaxiality between the material and the first component and the second component when pushing the material to escape outward, thus further improving the wrapping quality.

[0021] In the present invention, the pallet also includes a fence, which is used to support the material before wrapping. When the material is placed on the pallet, the fence can also be used to position the material so that the material can be basically coaxial with the first component and the second component, which is beneficial to improve the wrapping quality.

[0035] Example 1

[0036] like Figures 2 to 5 An efficient enclosing device shown includes a first component 1, a third component 2 and a second component 3 arranged up and down.

[0037] The first component 1 forms a first hollow cavity with an inner diameter of A1; the second component 2 forms a second hollow cavity with an inner diameter of A2; the third component 3 forms a third hollow cavity with an inner diameter of A3; the first component 1, the third component 2 and the second component 3 are arranged sequentially from bottom to top, A3 is greater than A1 and less than A2, and the first component 1, the second component 2 and the third component 3 are coaxial. In other embodiments of the present invention, a fourth, a fifth and other components may also be included, and the inner diameter of the hollow cavity enclosed by the components sequentially arranged from bottom to top gradually increases.

[0038] The second member 2, the third member 3 and the first member 1 can be moved closer or farther away from each other under the action of the external first driving unit 100 to enclose the materials in the first hollow cavity, the third hollow cavity and the second hollow cavity. In this embodiment, a vertical plate 4, a first guide shaft 5 and a second guide shaft 6 are also included.

[0039] like Figure 3 As shown, the vertical plate 4 is fixedly arranged, and a vertically extending guide rail 41 is provided on the vertical plate 4. The first component 1 is fixedly provided with a first arm 11, which extends horizontally and is slidably connected to the guide rail 41; the second component 2 is fixedly connected with a second arm 21, which extends horizontally and is slidably connected to the guide rail 41; the third component 3 is fixedly connected with a third arm 31, which extends horizontally and is slidably connected to the guide rail 41. At this time, the ends of the first arm 11, the second arm 21 and the third arm 31 are all slidably connected to the vertical plate 4 up and down; in this embodiment, the first driving unit 100 includes a first motor fixedly arranged on the vertical plate 4, the first motor transmission shaft is connected to the lead screw through a coupling, the two ends of the lead screw are rotatably connected to the vertical plate 4, and the lead screw nut sleeved on the lead screw is fixedly connected to the second arm 21, so that the first driving unit 100 can drive the second component 2 to move up and down along the guide rail.

[0040] like Figure 3As shown, the first guide shaft 5 is fixedly connected to the third arm 31 upward and passes through the first arm 11 downward to be slidably connected to the first arm 11 up and down, and the first guide shaft 5 extends out of the first arm 11 and is fixedly provided with a first retaining ring at the lower end thereof, so that when the first retaining ring abuts against the first arm 11 upward, the third component 3 can drive the first component 1 to move upward; the second guide shaft 6 is fixedly connected to the second arm 21 upward and passes through the third arm 31 downward to be slidably connected to the third arm 31 up and down, and the second guide shaft 6 extends out of the third arm 31 and is fixedly provided with a second retaining ring at the lower end thereof, so that when the second retaining ring abuts against the third arm 31 upward, the second component 2 can drive the third component 3 to move upward, so that the material can be supported progressively, and at the same time, the material can be supported in a larger vertical space, so that the material inclusion effect is better.

[0041] In this embodiment, the first component 1, the third component 3 and the second component 2 are all in annular shape and have a circular cross-section, so that the three components not only lift the material during the process of contact with the material, but also allow the material to slide smoothly relative to the components, further ensuring the wrapping effect.

[0042] like Figure 2 and 4 As shown, it is adapted to the first component 1, the third component 3 and the second component 2, and also includes a fixed core mold 7, the core mold 7 is larger at the top and smaller at the bottom and is in a conical shape, the core mold 7 is sleeved in the first component 1, the third component 3 and the second component 2, and the core mold 7 is coaxially arranged with the first component 1, the third component 3 and the second component 2. When the second component 2 and the third component 3 rise to the upper limit position relative to the first component 1, a wrapping cavity for accommodating materials is formed between the first component 1 and the core mold 7, between the third component 3 and the core mold 7, and between the second component 2 and the core mold 7. In this way, the material can be limited inside and outside, so that the material wrapping is more uniform and smoother.

[0043] In addition, the first guide shaft 5 and the second guide shaft 6 are also designed so that when the second component 2 and the third component 3 rise to the upper limit position relative to the first component 1, the conical cavity formed by the first component 1, the third component 3 and the second component 2 has a taper consistent with the taper of the core mold 7, thereby further supporting the material being gathered.

[0044] like Figure 4 and 5 As shown, the core mold 7 is a hollow structure, and also includes a push-out unit 8, and the push-out unit 8 is sleeved in the core mold 7;

[0045] In this embodiment, the ejection unit 8 includes a plurality of ejection arms 81, a mounting seat 82, and swing arms 83 arranged one by one corresponding to the ejection arms 81. Figure 5As shown, the mounting seat 82 is fixedly arranged and adapted to the core mold 7. The mounting seat 82 is large at the top and small at the bottom and is in the shape of a quadrangular pyramid. In other embodiments of the present invention, the mounting seat can also be other multi-sided pyramids. Four slide rails 85 are correspondingly fixed on the outer wall surface of the mounting seat 82. There are four swing arms 83 and they are arranged one by one corresponding to the four slide rails 85. The push arm 81 is arranged horizontally. The push arm 81 is slidably connected to the slide rail 85 at a roughly middle position. The first end of the push arm 81 can pass through the first through hole on the core mold 7 and extend to the core mold 7. Outside the mold 7, the second end of the push arm 81 passes through the mounting seat 82 and is hinged to the first end of the swing arm 83. The second ends of the four swing arms 83 are all hinged to the movable seat 84. The second driving unit 200 can drive the movable seat 84 to move up and down, thereby driving the push arm 81 to move up and down. When the push arm 81 abuts against the upper end surface of the material in the enclosing cavity and moves, the enclosed material can pass through the first hollow cavity with a smaller inner diameter to further enclose the material, complete the enclosing, and complete the blanking operation at the same time. The design is ingenious.

[0046] Taking into account the final wrapping effect, generally speaking, the closer the inner diameter A1 of the first hollow cavity is to the outer diameter of the finished material after wrapping, the better. In this embodiment, in order to ensure the smooth falling of the material after wrapping, the difference between the outer diameter of the first hollow cavity A1 and the finished material after wrapping is controlled at 1 to 2.5 cm, preferably 1.5 cm.

[0047] like Figure 3 As shown, it also includes a pallet 9, which is arranged below the first component 1. The outer edge of the pallet 9 includes a fence 10, and the pallet 9 is configured so that when the material is placed on the pallet 9 and laterally abuts against the fence 10, the material is coaxial with the first component 1, the third component 3 and the second component 2, so that the material can be easily positioned and has good position accuracy relative to the three components.

[0048] In this embodiment, the support plate 9 is arranged close to the first component 1, and a material drop opening 91 is also provided on the support plate 9. The material drop opening 91 is coaxial with the first component 1, so as to facilitate the wrapped material to drop downward to enter the next process.

[0049] A working method of a wrapping device, using the wrapping device as described above, comprises the following steps:

[0050] A. Prepare the material. Fold the long strip filter material to form several continuous W-shaped folds, such as Figure 6 Then the two free ends of the long strip filter material are bonded and laid flat, so as to obtain the material to be wrapped, such as Figure 7 As shown;

[0051] B. Place the material horizontally above the second component 2. At this time, the material covers the third component 3 and the first frame 1 and is supported by the support plate 9. Then, the material is laterally abutted against the enclosure 10. The material is positioned in this way so that the material and the three components have good relative position accuracy;

[0052] C. Then the first motor is activated, and the second member 2 is lifted upwards first. When the second retaining ring abuts against the third arm 31 upwards, the third member 3 moves upwards synchronously with the second member 2. When the first retaining ring abuts against the first arm 11 upwards, the first member 1 moves upwards synchronously with the third member 3 and the second member 2. That is, the first member 1, the third member 3 and the second member 2 are changed from a close state to a separated state. At this time, the first member 1, the third member 3 and the second member 2 are enclosed together to form a conical cavity. In this process, the material is wrapped toward the center and is vertically straightened.

[0053] D. Then the second driving unit 200 is actuated to move the push arm 81 downward and abut against the upper end surface of the material. Since the inner diameter of the first component 1 is slightly larger than the outer diameter of the finished product after the material is wrapped, and the material is conical at this time, the outer diameter of the lower end of the material is compressed and smaller than the inner diameter of the first component 1. When the push arm 81 moves downward to push the material downward through the first hollow cavity formed by the first component 1, the material can smoothly pass through the first component 1 and escape from the wrapping cavity and fall from the material dropout. In the process of escaping, the upper end of the material is further wrapped, so that the falling is completed and the wrapping action is completed at the same time;

[0054] E. Then the first driving unit 100 is activated to restore the first component 1, the third component 3 and the second component 2 from the separated state to the close state, that is, when the first component 1, the third component 3 and the second component 2 are in the close state, the first arm 11, the third arm 31 and the second arm 21 are stacked up and down, and at the same time the second driving unit 200 is activated to move the push arm 81 upward and reset to the initial position.

[0055] Example 2

[0056] The difference between Example 2 and Example 1 is that the enclosing device only includes the first component 1 and the second component, and when the second component 2 rises to the upper limit relative to the first component 1, the second component 2 and the first component 1 enclose a cone that is larger at the top and smaller at the bottom, thereby enclosing the material.

[0057] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications made based on the present invention belong to the scope of protection claimed by the present invention.
