Description

Technical Field

[0001] The present invention belongs to the technical field of hot melt adhesive filtration. More specifically, it particularly relates to a special filter device for hot melt adhesive production and discharging. Background Art

[0002] Currently, during the glue discharging process of hot melt glue production enterprises, filters are required. Generally, only basket filters or filter element filter devices are available in the market, and enterprises usually choose filter element filters the most. The characteristics of filter element filter devices are that the device size is relatively large. During the production process, the glue capacity inside the filter is relatively large. Each time the filter element is replaced, it is rather troublesome, and a lot of glue is wasted each time the filter element is replaced. Each time the equipment is started and stopped, due to the large size of the equipment, if the glue inside the filter cannot melt, it will affect the production and discharging.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a special filter device for hot melt adhesive production and discharging is provided, with the expectation of achieving a more practical value purpose. Summary of the Invention

[0004] In order to solve the technical problems of blocking the mesh and replacing the filter mesh of the hot melt adhesive discharging filter, excessive residual glue in the discharging filter, variety switching, the need to drain the residual glue in the previous filter before discharging, and the problems that the glue in the filter does not melt and has a long melting time during the process of stopping production and restarting the machine, the present invention provides a special filter device for hot melt adhesive production and discharging, and its purpose and efficacy are achieved by the following specific technical means:

[0005] A special filter device for hot melt adhesive production and discharging includes a filter housing, a filter skeleton, and a filter mesh frame. The filter skeleton includes a skeleton cover, a skeleton bottom plate, and a plurality of reinforcing ribs. The skeleton cover and the skeleton bottom plate are fixedly connected by a plurality of reinforcing ribs. A through hole is opened in the middle of the skeleton bottom plate. The filter mesh frame is wrapped on the surface of the filter skeleton. A filter bottom plate is arranged at the bottom of the filter mesh frame. A plurality of buckle parts are fixedly connected to the surface of the filter bottom plate. A communication hole is opened in the filter bottom plate. A push sleeve is slidably arranged in the communication hole respectively. One end of the push sleeve penetrates through the communication hole and extends to the bottom of the filter bottom plate. The filter housing is sleeved on the surface of the filter mesh frame. An outlet pipe is connected to the top of the skeleton cover. An inlet pipe is connected to the bottom of the filter housing.

[0006] Furthermore, two raised blocks are fixedly connected to one side surface of each of the buckle parts away from each other. There is a gap between the two raised blocks. The longitudinal section of the raised block is a right trapezoidal structure.

[0007] Further, one end of the pushing sleeve that has not passed through the communication hole is inclined and contacts the inclined surface on the raised block at the bottom of the buckle member. One end of the pushing sleeve that passes through the communication hole is fixedly connected through a pushing block.

[0008] Further, the filter mesh frame is arranged between the skeleton cover and the filter bottom plate. A plurality of filter holes are provided on the filter mesh frame, and the filter mesh frame is sleeved on the surface of the reinforcing ribs arranged in an annular array.

[0009] Further, a limiting groove is provided at the bottom of the skeleton cover. One end of the filter mesh frame is movably inserted into the limiting groove. An annular screw sleeve is also installed at the bottom of the skeleton cover, and the radius of the screw sleeve is larger than the radius of the limiting groove.

[0010] Further, a threaded groove is provided on the inner wall of the top of the filter housing and is threadedly connected to the threaded groove on the surface of the screw sleeve.

[0011] Further, threaded grooves are respectively provided on the outlet pipe and the inlet pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The filter designed in the present invention is small in volume and is composed of a filter housing, a filter mesh frame and a filter skeleton. The small structure makes the device more convenient to operate during use, and at the same time can reduce the residue of glue in the filter, and greatly reduces the waste rate of glue.

[0014] In the present invention, by designing the filter mesh frame to wrap the entire reinforcing rib, the number of filter mesh frames in the traditional filter can be reduced. By designing a single filter mesh frame, the gap between the filter housing and the filter mesh frame is smaller during filtration, reducing the possibility of excessive glue residue. A filter bottom plate is designed at the bottom of the filter mesh frame, and the filter bottom plate can be connected and disassembled with the skeleton bottom plate through a buckle member, which can facilitate the rapid replacement of the filter mesh frame. The inlet and outlet ends of the filter also adopt a threaded groove structure, which can be quickly connected to other devices. The device is convenient for replacing the filter mesh and can also reduce the waste rate of glue. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following further describes the embodiments of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] Embodiment:

[0025] As shown in the attached Figure 1 to the attached Figure 6 as shown:

[0026] The present invention provides a special hot melt adhesive production and discharging filter device, including a filter housing 1, a filter skeleton and a filter mesh frame 5. The filter skeleton includes a skeleton cover 2, a skeleton bottom plate 10 and a plurality of reinforcing ribs 8. The skeleton cover 2 and the skeleton bottom plate 10 are fixedly connected through a plurality of reinforcing ribs 8. A through hole 9 is opened in the middle of the skeleton bottom plate 10. The filter mesh frame 5 is wrapped on the surface of the filter skeleton. A filter bottom plate 6 is arranged at the bottom of the filter mesh frame 5. A plurality of buckle parts 11 are fixedly connected to the surface of the filter bottom plate 6. Communication holes are opened in the filter bottom plate 6. Pushing sleeves 12 are respectively slidably arranged in the communication holes. One end of the pushing sleeve 12 penetrates through the communication hole and extends to the bottom of the filter bottom plate 6. The filter housing 1 is sleeved on the surface of the filter mesh frame 5. An outlet pipe 3 is connected to the top of the skeleton cover 2. An inlet pipe 4 is connected to the bottom of the filter housing 1.

[0027] Among them, the filter housing 1 is made of stainless steel.

[0028] As an embodiment of the present invention, two protruding blocks 13 are fixedly connected to the mutually remote side surfaces of the buckle part 11. There is a gap between the two protruding blocks 13. The longitudinal section of the protruding block 13 is a right trapezoid structure;

[0029] Among them, as Figure 6, the right-angled surfaces of the two protruding blocks 13 are close to each other. The protruding block 13 at the bottom of the buckle 11 is larger than the protruding block 13 at the top. To facilitate the extrusion of the buckle 11 when the pushing sleeve 12 contacts the bottom protruding block 13, after the protruding block 13 at the top is extruded, it can move within the through hole 9, move away from the inner wall of the through hole 9, and can be separated from the through hole 9;

[0030] When fixing, the protruding block 13 at the upper end of the buckle 11 passes through the through hole 9, and the through hole 9 is movably clamped between the two protruding blocks 13, so as to be fixed.

[0031] As an embodiment of the present invention, one end of the pushing sleeve 12 that does not pass through the communication hole is inclined and contacts the inclined surface of the protruding block 13 at the bottom of the buckle 11. One end of the pushing sleeve 12 that passes through the communication hole is fixedly connected by a push block;

[0032] Among them, as Figure 6 , one end of the pushing sleeve 12 is inclined, which can better squeeze the protruding block 13 when pushing. Moreover, the pushing sleeve 12 is arranged below the protruding block 13, and the gravity is downward. When not in use, it does not affect the fixing effect of the protruding block 13 on the entire filter screen frame 5.

[0033] As an embodiment of the present invention, the filter screen frame 5 is arranged between the skeleton cover 2 and the filter bottom plate 6. A plurality of filter holes are provided on the filter screen frame 5. The filter screen frame 5 is sleeved on the surface of the reinforcing ribs 8 arranged in an annular array. A filter screen is fixedly attached to the surface of the filter screen frame 5 by a tie strap, and the filter screen wraps around the surface of the filter screen frame 5.

[0034] As an embodiment of the present invention, a limiting groove is provided at the bottom of the skeleton cover 2. One end of the filter screen frame 5 is movably inserted into the limiting groove. An annular screw socket 7 is also installed at the bottom of the skeleton cover 2, and the radius of the screw socket 7 is larger than the radius of the limiting groove.

[0035] As an embodiment of the present invention, a threaded groove is provided on the inner wall of the top of the filter housing 1 and is threadedly connected to the threaded groove on the surface of the screw socket 7.

[0036] As an embodiment of the present invention, threaded grooves are respectively provided on the outlet pipe 3 and the inlet pipe 4.

[0037] When the filter in the present invention is implemented, the inlet pipe 4 is connected to the external glue raw material barrel, the outlet pipe 3 is connected to the external filter barrel, and filtration is carried out through the filter mesh frame 5. After the filtration is completed, by rotating the filter housing 1 relative to the skeleton cover 2, the skeleton cover 2 can be separated from the screw-threaded sleeve 7, thereby exposing the filter mesh frame 5. Push the push plate upward, and the push sleeve 12 squeezes the raised block 13 on the buckle member 11, and the raised block 13 moves away from the through port 9, so that the filter bottom plate 6 can be separated from the skeleton bottom plate 10, and thus the filter mesh frame 5 is no longer restricted by the skeleton cover 2 and the filter bottom plate 6, and then it can be replaced.

[0038] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention so as to design various embodiments with various modifications suitable for a particular purpose.
