[0041] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. In the drawings, the X-axis is the longitudinal direction, also the front-to-back direction, the Y-axis is the transverse direction, also the left-right direction, and the Z-axis is the vertical direction, also the up-down direction. The orientation or position indicated in the present invention is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description.

[0042] The filter paper assembly mechanism of the bridge filter processing equipment includes a gluing device 1, a filter paper primary installation component 2, a flipping component and a filter paper secondary installation component 5. The filter paper 40 passes through the filter paper primary installation component 2, the flipping component and the filter paper secondary installation component 5 in sequence. The gluing device 1 applies glue to the installation grooves of the upper end cover 41 and the lower end cover 42. The filter paper primary installation component 2 installs one end of the filter paper into the installation groove of the upper end cover 41 after gluing, and the end without the lower end cover faces upward. The flipping component flips the filter paper 40 installed with the upper end cover 180 degrees, so that the end without the lower end cover faces downward. The filter paper secondary installation component 5 installs the other end of the filter paper into the installation groove of the lower end cover 42 after gluing.

[0043] The filter paper first installation component 2 includes a filter paper clamping assembly, a pushing assembly and a mobile frame 14, and the filter paper clamping assembly and the pushing assembly are arranged on the mobile frame 14. The filter paper clamping assembly includes an upper clamping member 16 and a lower clamping member 17. When the lower clamping member 17 is closed, the minimum inner diameter of the lower clamping opening 28 thereof is smaller than the inner diameter of the upper clamping opening 27 when the upper clamping member 16 is closed, and the upper clamping opening 27 and the lower clamping opening 28 are on the same center line. The lower clamping member 17 includes a first lower clamping head 21 and a second lower clamping head 22. The first lower clamping head and the second lower clamping head include a filter paper clamping portion 26 for clamping the filter paper. The clamping surface 20 of the filter paper clamping portion 26 has an inclined section 25. After the first lower clamping head 21 and the second lower clamping head 22 are closed, the inclined section 25 of the lower clamping opening is inverted truncated cone shape, and the lower clamping opening 28 plays a tightening and guiding role. The push assembly includes a push head 15 that rises and falls, and the push head is arranged above the upper clamping member 16 and corresponds to the upper clamping port 27, and is used to push the filter paper 40. When taking the filter paper, the upper clamping member 16 clamps the upper end of the filter paper, and the lower clamping member 17 is not closed; when assembling the filter paper, the lower clamping member 17 is closed and clamps the lower end of the filter paper, and the push head 15 moves downward and pushes the filter paper 40, and the lower end of the filter paper is tightened through the lower clamping port 28 and enters the installation groove. Specifically, the cylindrical filter paper 40 is sleeved from the upper end cover of the pressure relief valve housing 10 downward outside the pressure relief valve housing 10. When taking the filter paper, only the upper clamping member 16 is used to clamp the upper end of the filter paper, so that the filter paper retains a larger inner hole, so that it can be easily sleeved outside the pressure relief valve housing 10. After the upper clamping member 16 clamps the filter paper, the movable frame 14 moves so that the filter paper clamped by the upper clamping member 16 is sleeved outside the pressure relief valve housing 10. At this time, the bottom of the filter paper is close to the mounting groove of the upper end cover 41, and the lower clamping member 17 is closed to tighten the lower end of the loose filter paper. The inverted truncated cone-shaped clamping opening forms a tightening guide opening. The lower end of the filter paper is smaller than the upper end of the filter paper. The pushing head 15 moves downward and pushes the filter paper 40. The filter paper moves downward relative to the upper clamping member 16 and the lower clamping member 17. The lower end of the filter paper is tightened and guided through the lower clamping opening 28 of the lower clamping member 17 to smoothly enter the mounting groove, thereby realizing automatic assembly of the filter paper.

[0044] The inclined section 25 of the filter paper clamping part 26 has a vertical section 24 extending downward from the clamping surface. After the first lower clamping head 21 and the second lower clamping head 22 are closed, the vertical section 24 of the lower clamping opening is cylindrical. After the inclined section 25 at the lower end of the filter paper is gradually tightened, the cylindrical vertical section 24 plays a shaping and stabilizing role, so that the filter paper portion entering the installation groove is in a tightened straight tube shape before entering. In this way, the filter paper portion entering the installation groove has a stable shape and matches the installation groove, and the assembly effect is better.

[0045] The first lower clamping head and the second lower clamping head also include an end cap clamping portion 23 for clamping the end cap, and the end cap clamping portion 23 is arranged below the filter paper clamping portion 26, and the clamping surface of the end cap clamping portion 23 is consistent with the side surface of the end cap. When the lower clamping member 17 is closed, not only the lower end of the filter paper is clamped, but also the upper end cap 41 is clamped together, that is to say, when the mobile frame 14 moves, the filter paper and the upper end cap 41 move together, so that the push head 15 can press the filter paper into the mounting groove of the upper end cap 41 during the movement, thereby improving the efficiency of the filter paper assembly. After the filter paper 40 is assembled with the upper end cap 41, it is moved to the shaping station 4 by the mobile frame 14 for shaping.

[0046] The first lower clamping head 21 and the second lower clamping head 22 move horizontally. When they move toward each other, they are closed, and when they move away from each other, they are opened. The movable frame 14 is provided with a guide member 19 for the horizontal movement of the first lower clamping head and the second lower clamping head. The horizontal movement of the first lower clamping head and the second lower clamping head is stable and the clamping and tightening accuracy is high.

[0047] The mobile frame 14 moves longitudinally and rises and falls; a product taking component 18 is also provided on the mobile frame 14, and the product taking component 18 and the filter paper clamping component are arranged side by side longitudinally, and the product taking component 18 includes a product taking clamp 35. The movement of the mobile frame 14 drives the filter paper clamping component and the product taking component 18 to move synchronously, and when the filter paper clamping component sends the assembled filter paper to the shaping station 4, the product taking component 18 clamps the shaped filter paper semi-finished product; when the filter paper clamping component takes the upper end cover 41 or assembles the filter paper, the product taking component 18 sends the shaped filter paper semi-finished product to the vacant filter paper station slot, thereby improving the efficiency of filter paper assembly.

[0048] The sample taking clamp 35 includes a plurality of vertically arranged sample taking clamping heads, which are evenly arranged on a circumference and move radially; when clamping, the plurality of sample taking clamping heads gather toward the center; when loosening, the sample taking clamping heads spread outwardly. The plurality of sample taking clamps 35 clamp the finalized filter paper semi-finished products by radial movement, shortening the movement stroke of the sample taking clamp 35 and providing more operating space for the filter paper clamping assembly. A counterweight block 39 is sleeved on the top of the filter paper, and the counterweight block 39 is tightly matched with the filter paper 40. The setting of the counterweight block 39 is to keep the filter paper in a cylindrical shape to avoid excessive looseness affecting the clamping operation. The clamping surface of the sample taking clamping head is stepped, and the sample taking clamping head clamps and supports the counterweight block 39, so the clamping effect is better.

[0049] The flipping component includes a clamping member 31, a steering member 32 for driving the clamping member to flip vertically, a shaking member for driving the clamping member to lift and lower reciprocately, and a lifting member for driving the clamping member to move up and down. The clamping member 31 clamps the filter paper semi-finished product assembled at one end and moves it upward to make it separate from the workpiece seat 6. The steering member 32 makes the filter paper rotate 180 degrees vertically so that the end with the counterweight 39 faces downward. The shaking member drives the clamping member to move quickly up and down in a short stroke to achieve a shaking effect, so that the counterweight 39 is separated from the filter paper semi-finished product. After the counterweight 39 is removed from the filter paper semi-finished product, the clamping member 31 moves downward to deliver the flipped and counterweighted filter paper semi-finished product to the workpiece seat 6.

[0050] The flipping component also includes a moving component that drives the clamping member to move horizontally, and the moving component drives the clamping member 31 to return to horizontal position after turning. Figure 6 , the horizontal position of the flipped filter paper semi-finished product relative to the workpiece seat 6 changes, and the position of the flipped filter paper semi-finished product does not correspond to the position of the filter paper on the workpiece seat 6, so the moving component is used to reset it horizontally, so that the lifting component drives the clamping member to move down, and the filter paper semi-finished product returns to the position of taking the filter paper. The lifting component drives the clamping member to rise to the shaking station to provide operating space for the weight removal shaking.

[0051] The steering component 32 includes a rotating shaft; the shaking component includes a slide plate 33 and a slide seat 34, and the slide plate 33 is vertically reciprocated and lifted on the slide seat 34; the moving component includes a moving seat 37, and the moving seat 37 is provided with a horizontally arranged first guide rail 36; the lifting component includes a vertically arranged second guide rail 38; the clamping member 31 is installed on the rotating shaft, the rotating shaft is rotatably arranged on the slide plate 33, the slide seat 34 is slidably arranged on the first guide rail 36, and the moving seat 37 is lifted and lowered on the second guide rail 38. The movement, lifting and rotation of each component can be driven by a cylinder, or a motor combined with a screw mechanism, a synchronous belt, a gear rack and other structures to achieve.

[0052] The filter paper secondary installation component 5 can adopt the same structure as the filter paper primary installation component 2; in addition, since there is no pressure relief valve housing on the lower end cover 42, there is no need to consider whether the filter paper can be sleeved outside the pressure relief valve housing 10. The filter paper secondary installation component 5 can use a clamp to tighten the end of the filter paper and send it into the installation groove of the lower end cover 42.

[0053] The gluing device 1 includes a gluing component, and the gluing component includes a gluing head 29. The glue is extruded through the gluing head 29 and applied to the mounting groove of the upper end cover 41 or the lower end cover 42; it is better that the gluing head can be raised and lowered. When gluing, the gluing head moves down into the mounting groove. Because the filter paper assembly is divided into two times, the gluing component can be provided in two groups, which are used for gluing the upper end cover 41 and the lower end cover 42 respectively. In order to reduce the equipment cost, the gluing component adopts one group. The gluing device 1 also includes a crossbeam 30, and the gluing component moves horizontally on the crossbeam 30 to the first gluing station 11 or the second gluing station 13. The gluing component can be glued to two stations by moving on the crossbeam 30. The two stations share one gluing component for gluing, which can not only realize automatic gluing, but also reduce equipment costs.

[0054] The first gluing station 11 and the second gluing station 13 are arranged laterally symmetrically, and a flipping station 12 is arranged between the first gluing station 11 and the second gluing station 13. The filter paper first installation component 2 and the filter paper secondary installation component 5 are respectively arranged in the first gluing station 11 and the second gluing station 13, and the flipping component is arranged in the flipping station 12. A guide rail 3 is arranged below the crossbeam 30, and a workpiece seat 6 is slidably arranged on the guide rail. The workpiece seat 6 passes through the first gluing station 11, the flipping station 12 and the second gluing station 13 in sequence along the guide rail 3. The workpiece seat 6 is provided with a first workpiece groove 7 and a second workpiece groove 9, the upper end cover 41 is placed in the first workpiece groove 7, and the lower end cover 42 is placed in the second workpiece groove 9, see the attached Figure 1 , the first workpiece groove 7 and the second workpiece groove 9 are arranged side by side in the first gluing station 11 and the second gluing station 13, and a filter paper workpiece groove 8 is provided between the two, and the uninstalled filter paper 40 is placed in the filter paper workpiece groove 8. At the first gluing station 11, the gluing head 29 corresponds to the first workpiece groove 7, and the upper end cover 41 is glued. At the second gluing station 13, the gluing head 29 corresponds to the second workpiece groove 9, and the lower end cover 42 is glued. The gluing component only needs to move horizontally to correspond to the gluing position on the workpiece seat 6, which not only has a more streamlined structure and lower equipment cost, but also the gluing component can be in place more quickly.

[0055] The workpiece seat 6 is connected to a transmission chain that drives it to move on the guide rail 3. The transmission chain is set on a transmission wheel, and the transmission wheel is connected to a motor that drives it to rotate horizontally. The motor drives the transmission wheel to rotate, and the transmission wheel drives the transmission chain to drive, so that the workpiece seat 6 moves along the guide rail. The workpiece seats 6 are provided with a plurality of them and are evenly distributed on the transmission chain. Each workstation corresponds to a workpiece seat 6. Each workstation can work at the same time, and the workpiece seats 6 cooperate with each workstation to improve production efficiency.

[0056] The two ends of the filter paper are bonded to the upper end cover 41 and the lower end cover 42 respectively. It is best if the shape of the glue coating is consistent with the shape of the bonding position. Therefore, the shape of the glue coating is circular. The first workpiece groove 7 and the second workpiece groove 9 both have a through hole that penetrates the workpiece seat 6; the first gluing station 11 and the second gluing station 13 are respectively provided with a first rotating component and a second rotating component, and the first rotating component and the second rotating component are arranged below the workpiece seat 6 and correspond to the through hole of the first workpiece groove 7 on the workpiece seat 6 of the first gluing station 11 and the through hole of the second workpiece groove 9 on the workpiece seat 6 of the second gluing station 13. When gluing, the gluing head 29 does not move, and the first rotating component or the second rotating component passes through the through hole of the corresponding station, so that the end cover of the corresponding station rotates, and the end cover rotates relative to the gluing head 29, so that the glue extruded by the gluing head 29 is coated in the mounting groove of the end cover, and is circular. The first rotating component includes a top plate that rises and falls and a driving member that drives the top plate to rotate, and the outer diameter of the top plate is smaller than the aperture of the through hole. The top plate moves up through the through hole and pushes the end cover of the corresponding station to move up, so that the end cover does not contact the workpiece seat 6, and the driving member drives the top plate to rotate, so that the end cover rotates. The second rotating component can also adopt the same structure.

[0057] The working principle of the preferred embodiment is further described below in conjunction with the accompanying drawings: the upper end cover 41, the filter paper 40, and the lower end cover 42 are placed in the first workpiece slot 7, the filter paper workpiece slot 8, and the second workpiece slot 9 of the workpiece seat 6 in sequence, and the transmission chain moves the workpiece seat 6 along the guide rail 3 to the first gluing station 11, the gluing head 29 moves down, and the top plate of the first rotating component moves up, pushing the upper end cover 41 of the first gluing station 11 to move up, so that the gluing head 29 enters the installation slot of the upper end cover 41 or approaches the installation slot, and the gluing head 29 squeezes out the glue, and the top plate drives the upper end cover 41 to rotate one circle. After the upper end cover 41 completes the gluing, the top plate moves down and resets, the upper end cover 41 is placed in the first workpiece slot 7, the gluing head 29 moves up and moves along the crossbeam 30 to the second gluing station 13, and the lower end cover 42 of the second gluing station 13 is glued. When the upper end cover 41 is glued, the movable frame 14 of the filter paper first installation component 2 moves to the position where the filter paper is located. At this time, the product taking clamp 35 has clamped the shaped filter paper semi-finished product (one end of the filter paper is bonded to the upper end cover 41) from the shaping station 4, and the upper clamping member 16 clamps the upper end of the filter paper so that the filter paper retains a larger inner hole, and then the movable frame 14 moves up and then moves to the left to just above the upper end cover 41, and then the movable frame 14 moves down to cover the filter paper 40 on the outside of the pressure relief valve housing 10 connected to the upper end cover, and the lower end of the filter paper is close to the installation groove of the upper end cover 41, and the lower clamping member 17 is closed, the filter paper clamping part 26 clamps the lower end of the filter paper, and the end cover clamping part 23 clamps the upper end cover 41, the lower end of the filter paper is tightened, and the outer diameter becomes smaller; at the same time, the product taking clamp 35 sends the clamped shaped filter paper semi-finished product to the filter paper workpiece slot 8, and releases the filter paper semi-finished product. After the filter paper clamping part 26 clamps the upper end cover 41, the movable frame 14 moves up and moves to the right to the shaping station 4. During this process, the pushing head 15 moves down to push the filter paper 40 to move down relative to the upper clamping part 16 and the lower clamping part 17. The lower end of the filter paper passes through the inclined section 25 and the vertical section 24 of the filter paper clamping part 26. The inclined section 25 gradually tightens the filter paper and the vertical section 24 keeps the filter paper tightened. In this way, the lower end of the filter paper is smoothly tightened and introduced into the installation groove, and the lower end of the filter paper is bonded to the upper end cover 41. The bonded filter paper and the upper end cover 41 are sent to the shaping station 4, and the sample clamp 35 clamps the semi-finished filter paper that has been shaped.

[0058] When each station completes the operation, for example, after the upper end cover 41 of the first gluing station 11 is clamped, the transmission chain drives the workpiece seat 6 to move along the guide rail to the flipping station 12, and at the flipping station 12, the clamping member 31 clamps the semi-finished filter paper, and then the lifting component drives the clamping member to move upward, and the semi-finished filter paper leaves the workpiece seat 6, and the steering component 32 drives the clamping member to rotate 180 degrees clockwise, so that the counterweight block 39 of the semi-finished filter paper faces downward and the upper end cover 41 faces upward, and the moving component drives the clamping member to move horizontally to the top of the filter paper workpiece slot 8, and the shaking component drives the clamping member 31 to move back and forth rapidly up and down, and the short-stroke rapid movement causes the counterweight block 39 to separate from the filter paper, and then, the lifting component drives the clamping member to move downward, and the semi-finished filter paper without the counterweight block is delivered to the filter paper workpiece slot 8.

[0059] After the semi-finished filter paper on the workpiece seat 6 is deweighted and turned over at the turning station 12, it is sent to the second gluing station 13. At the second gluing station, the gluing head 29 glues the lower end cover 42, and the filter paper clamping assembly of the filter paper secondary installation component 5 clamps the semi-finished filter paper, while the product removal assembly of the filter paper secondary installation component 5 has clamped the finalized filter paper finished product from the shaping station 4 (the other end of the filter paper is bonded to the lower end cover 42). After the lower end cover 42 is glued, the filter paper secondary installation component 5 bonds the other end of the filter paper to the lower end cover 42, and the product removal assembly sends the finalized filter paper finished product to the filter paper workpiece slot 8; finally, the filter paper clamping assembly sends the finished product that has been bonded to the shaping station 4 for shaping, and the product removal assembly clamps the finalized finished product that has been shaped at the shaping station 4.
