Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rubber production equipment, and in particular to a quick-connect structure for a filter and a material cylinder. Background Technology
[0002] In the production of various rubber compounds, the rubber compound is usually stored in a material tank, and then extruded from the tank when needed. During the production process, due to uneven reaction or problems with the raw materials, particles or impurities are easily generated. Therefore, it is often necessary to connect a filter to the outlet of the material tank to remove impurities.
[0003] For example, utility model patent CN 222468216U discloses a clamp-on filter. As shown in the accompanying drawings, one end of the filter has a connecting flange, and the outlet of the feed cylinder also has a connecting flange. Because the filter is heavy, during connection, one installer needs to lift the filter, align the filter's connecting flange with the connecting flange at the feed cylinder's outlet, and then another installer uses bolts and nuts to further tighten and secure the two connecting flanges. Removal is done in the reverse order. However, this operation requires two people to work together, making the filter time-consuming, labor-intensive, and not particularly convenient to use. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a quick-connect structure for the filter and the material cylinder, which solves the problem of time-consuming and labor-intensive use of the filter and waste of manpower.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a quick-connect structure for a filter and a material cylinder, including a filter, a movable nut, and a dispensing pipe disposed at the bottom of the side wall of the material cylinder. The filter is provided with an inlet pipe and a dispensing pipe at both ends. An outer limiting flange is integrally formed in the middle of the outer wall of the inlet pipe. The movable nut is movably sleeved on the inlet pipe. An inner limiting flange is integrally formed near one end of the inner wall of the movable nut. The inlet pipe can be inserted into the dispensing pipe. When the movable nut is threadedly connected to the dispensing pipe, the inner limiting flange and the ends of the dispensing pipe are respectively pressed against the two ends of the outer limiting flange.
[0006] As a further embodiment, the outer wall of the dispensing tube is provided with external threads, the inner wall of the movable nut is provided with internal threads, the internal threads extend from one end of the movable nut to the inner limiting flange, and the internal threads are threadedly connected to the external threads.
[0007] As a further option, a wrench is provided on the outer wall of the movable nut.
[0008] As a further embodiment, the filter includes a first cone, a second cone, and a filter unit. A hinge unit is provided on one side of the connection between the first cone and the second cone, and a fastening unit is provided on the other side of the connection between the first cone and the second cone. The filter unit is sandwiched between the first cone and the second cone. Both the first cone and the second cone are hollow structures with through-ends. The feed pipe is located at one end of the first cone, and the discharge pipe is located at the end of the second cone away from the first cone. The feed pipe and the discharge pipe are connected.
[0009] As a further embodiment, the first cone has a first cavity inside, and the second cone has a second cavity inside, with the feed pipe, the first cavity, the second cavity, and the discharge pipe connected in sequence.
[0010] As a further embodiment, the filtration unit includes a filter screen and a perforated plate stacked on top of each other, with the filter screen close to the first cone and the perforated plate close to the second cone, and an annular groove for accommodating the filter screen and the perforated plate is formed between the first cone and the second cone.
[0011] As a further embodiment, the hinge unit includes a first hinge fixed to a first cone and a second hinge fixed to a second cone, wherein the first hinge is hinged to the second hinge via a hinge axis.
[0012] As a further embodiment, the fastening unit includes a first connecting seat fixed to a first cone and a second connecting seat fixed to a second cone.

[0013] As a further embodiment, a washer is provided between the first cone and the second cone, the inner diameter of which is larger than the diameter of the filter screen and the perforated plate.
[0014] The beneficial effects of this utility model are as follows: When quickly connecting and fixing the filter to the material cylinder, the filter's inlet pipe can be inserted into the outlet pipe. One installer can use one hand to stabilize one end of the filter (the other end of the filter receives force through the outlet pipe), while the other installer can use the other hand to turn the movable nut, making the movable nut threadedly connected to the outlet pipe. At this time, the inner limiting flange and the end of the outlet pipe are respectively pressed against the two ends of the outer limiting flange, achieving a sealed connection, thus quickly connecting and fixing the filter to the material cylinder. Disassembly is performed in the reverse order. The entire operation requires only one person, quickly sealing the filter and material cylinder without leakage, thereby saving labor and improving production efficiency. Attached Figure Description

Detailed Implementation
[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] As attached Figure 1-2 As shown in Figure 4, this utility model provides a quick-connect structure for a filter 1 and a material cylinder 3, used to quickly connect and fix or disassemble the filter 1 and the material cylinder 3. The quick-connect structure includes a filter 1, a movable nut 2, and a dispensing pipe 31 located at the bottom of the side wall of the material cylinder 3. The filter 1 has an inlet pipe 11 and a outlet pipe 12 at its two ends. After the adhesive is discharged from the dispensing pipe 31, it enters the filter 1 through the inlet pipe 11 for filtration, and is then discharged from the outlet pipe 12. An outer limiting flange 111 is integrally formed in the middle of the outer wall of the inlet pipe 11. The movable nut 2 is movably fitted onto the inlet pipe 11 and can move flexibly. An inner limiting flange 21 is integrally formed near one end of the inner wall of the movable nut 2. The inlet pipe 11 can be inserted into the dispensing pipe 31. When the movable nut 2 and the dispensing pipe 31 are threadedly connected, the ends of the inner limiting flange 21 and the dispensing pipe 31 are respectively pressed against the two ends of the outer limiting flange 111.
[0022] Specifically, when quickly connecting and fixing the filter 1 to the material cylinder 3, the feed pipe 11 of the filter 1 can be inserted into the dispensing pipe 31. One installer can use one hand to hold one end of the filter 1 steady (the other end of the filter 1 receives force through the dispensing pipe 31), while the other installer can use the other hand to turn the movable nut 2, making the movable nut 2 threadedly connected to the dispensing pipe 31. At this time, the inner limiting flange 21 and the end of the dispensing pipe 31 are respectively pressed against the two ends of the outer limiting flange 111, achieving a sealed connection, thus quickly connecting and fixing the filter 1 to the material cylinder 3. Disassembly is performed in the reverse order. The entire operation requires only one person, quickly sealing the filter 1 to the material cylinder 3 without leakage, thus saving labor and improving production efficiency.
[0023] A further detailed description is provided in the attached document. Figure 2 , 4 As shown, the outer wall of the dispensing tube 31 is machined with external threads 311, and the inner wall of the movable nut 2 is machined with internal threads 22. The internal threads 22 extend from one end of the movable nut 2 to the inner limiting flange 21. The internal threads 22 and the external threads 311 are threadedly connected and fixed, realizing a sealed connection between the filter 1 and the material cylinder 3. Of course, as a further improvement, a wrench 4 can be welded to the outer wall of the movable nut 2, preferably an even set of mutually symmetrical wrenches 4, so that the installer can easily turn the movable nut 2 with the help of the wrench 4, which is more labor-saving.
[0024] As one example, as shown in the appendix Figure 3 As shown, the filter 1 includes a first cone 13, a second cone 14, and a filter unit 15. A hinge unit 16 is provided on one side of the connection between the first cone 13 and the second cone 14, and a fastening unit 17 is provided on the other side of the connection between the first cone 13 and the second cone 14. The filter unit 15 is sandwiched between the first cone 13 and the second cone 14. Both the first cone 13 and the second cone 14 are hollow structures with both ends through. The feed pipe 11 is fixed at one end of the first cone 13, and the discharge pipe 12 is fixed at the end of the second cone 14 away from the first cone 13. The feed pipe 11 and the discharge pipe 12 are connected.
[0025] Specifically, the first cone 13 and the second cone 14 are hinged together by a hinge unit 16. The first cone 13 and the second cone 14 can be easily opened by disassembling the fastening unit 17, allowing for cleaning or replacement of the filter unit 15. After the adhesive enters the first cone 13 through the feed pipe 11, it is filtered at the filter unit 15, then enters the second cone 14 and is discharged from the discharge pipe 12. It should be noted that the inner diameter of the ends of the first cone 13 and the second cone 14 that are closer to each other is larger, while the inner diameter of the ends that are farther apart is smaller. This maximizes the area of the filter unit 15, reduces the filtration pressure of the filter unit 15, and thus prevents adhesive blockage or poor flow.
[0026] For example, as shown in the appendix Figure 3 As shown, the first cone 13 has a first cavity 131 inside, and the second cone 14 has a second cavity 141 inside. The feed pipe 11, the first cavity 131, the second cavity 141, and the discharge pipe 12 are connected in sequence, and the rubber material passes through the feed pipe 11, the first cavity 131, the second cavity 141, and the discharge pipe 12 in sequence.
[0027] As one embodiment, see attached Figure 3 As shown, the filter unit 15 includes a filter screen 151 and a perforated plate 152 stacked on top of each other. The filter screen 151 is close to the first cone 13, and the perforated plate 152 is close to the second cone 14. An annular groove 18 is formed between the first cone 13 and the second cone 14 to accommodate the filter screen 151 and the perforated plate 152. The annular groove 18 facilitates the installation and fixing of the filter screen 151 and the perforated plate 152, while preventing the filter screen 151 and the perforated plate 152 from shifting positions during the filtration process, which could lead to glue leakage. The filter screen 151 is placed close to the first cone 13 to filter the glue, while the perforated plate 152 is placed close to the second cone 14 to support the filter screen 151, preventing the filter screen 151 from deforming due to excessive filtration pressure. A washer 5 is provided between the first cone 13 and the second cone 14. The washer 5 is clamped between the first cone 13 and the second cone 14, and the inner diameter of the washer 5 is larger than the diameter of the filter screen 151 and the perforated plate 152, thereby preventing glue leakage at the filter screen 151 and the perforated plate 152.
[0028] As another embodiment, see attached Figure 3 As shown, the hinge unit 16 includes a first hinge 161 fixed to the first cone 13 and a second hinge 162 fixed to the second cone 14. The first hinge 161 is hinged to the second hinge 162 through a hinge shaft 163, thereby allowing the first cone 13 and the second cone 14 to rotate hingedly.
[0029] Additionally, as attached Figure 3 As shown, the fastening unit 17 includes a first connecting seat 171 fixed to the first cone 13 and a second connecting seat 172 fixed to the second cone 14. A bolt 173 is rotatably provided inside the first connecting seat 171, that is, the bolt 173 can rotate around the first connecting seat 171, and the bolt 173 can pass through the second connecting seat 172 and be connected and fixed with the eye nut 174. By tightening the eye nut 174 and the bolt 173, the first cone 13 and the second cone 14 clamp the filter unit 15.
[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
