Description

Technical Field

[0002] Filters used in the manufacture of beverages (such as beer, etc.) usually involve an annular support ring (metal cylinder ring), which serves as a support for the filter body and also ensures the overall assembly.

[0003] In the prior art, in order to facilitate assembly and connection, the edges at both ends of the annular support ring need to be folded to form annular flanges to ensure that the filter mesh and the locking structure are placed at both ends. However, for the manufacture of the annular support ring, a tensioning disk is usually used. After the annular support ring is set on the tensioning disk, it is propped up and fixed by the tensioning disk. One end edge of the annular support ring extends along the axial direction of the tensioning disk, and the edge is folded by a folding roller. After folding, it is disassembled and assembled, and the other end edge of the annular support ring is folded. This manufacturing method results in the production of each annular support ring requiring two assembly with the tensioning disk, which is time-consuming and labor-intensive, with low production efficiency and poor practicality.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Please also read Figure 1 and Figure 2 , the double-edge folding device for an annular support ring provided by the present invention is now described. The double-edge folding device for an annular support ring includes a frame 10, a tensioning assembly 20, a support structure 30 and a folding mechanism 40. The frame 10 has a mounting platform 11. The tensioning assembly 20 is arranged on the frame 10, and has a tensioning portion located above the mounting platform 11. The upper and lower ends of the tensioning portion are respectively provided with contact planes, and the tensioning portion can be provided for the annular support ring 50 to be sleeved. There are multiple support structures 30, each of which is arranged around the tensioning portion, and each of which can be provided for the annular support ring 50 sleeved on the tensioning portion, so that the upper and lower edges of the annular support ring 50 extend out of the two contact planes along the vertical direction. The folding mechanism 40 is arranged on the mounting platform 11, and has two bending portions located on both sides of the tensioning portion along the vertical direction and corresponding to the two contact planes. The folding mechanism 40 can drive the two bending portions to move along the radial direction of the tensioning portion to fold the two edges of the annular support ring 50 outward.

[0019] Compared with the prior art, the double-edge folding device for the annular support ring provided in this embodiment is capable of supporting the annular support ring 50 through the tensioning part by the tensioning assembly 20 arranged on the frame 10, thereby fixing the annular support ring 50. Each supporting structure 30 can ensure that the annular support ring 50 is supported before the tensioning part supports the annular support ring 50, so as to ensure that the lengths of the upper and lower edges of the annular support ring 50 extending out of the two contact planes are the same, thereby ensuring the folding effect. The folding mechanism 40 can fold the two edges extending out of the annular support ring 50 respectively by driving the horizontal movement of the two bending parts, and only requires the annular support ring 50 to be assembled once to achieve simultaneous folding of the two edges, thereby improving production efficiency and being highly practical.

[0020] In some embodiments, the folding mechanism 40 may be implemented as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The folding mechanism 40 includes a slide frame 41, a pressure roller 42, a lower folding assembly 43, an upper folding assembly 44 and a driving structure 47. The slide frame 41 is slidably connected to the slide rail 12 arranged on the mounting platform 11, and can move along the radial direction of the tensioning part. The slide frame 41 is also connected to the driving structure 47 arranged on the mounting platform 11. The pressure roller 42 is rotatably arranged at one end of the slide frame 41 close to the tensioning part, and the rotation axis is arranged parallel to the rotation axis of the tensioning part, and can be in rolling contact with the outer wall of the annular support ring 50. The lower folding assembly 43 is slidably arranged in the slide frame 41 along the radial direction of the tensioning part, and is located below the tensioning part. The lower folding assembly 43 is connected to the lower telescopic structure 45 arranged on the slide frame 41. The upper folding assembly 44 is slidably arranged in the slide frame 41 along the radial direction of the tensioning part, and is located above the tensioning part. The upper folding assembly 44 is connected to the upper telescopic structure 46 arranged on the slide frame 41.

[0021] The slide frame 41 can ensure that the pressure roller 42, the lower folding component 43 and the upper folding component 44 are driven to move closer to or away from the tensioning part. The tensioning part involves propping up the annular support ring 50 inside the annular support ring 50 to form a fixation, and the flanging process is to fold it toward the outside of the tensioning part. Therefore, the pressure roller 42 can ensure that the annular support ring 50 is clamped together with the tensioning part, and the annular support ring 50 can be pressed to ensure the quality of the folding. The lower folding component 43 corresponds to the edge of the bottom end of the annular support ring 50 that extends out of the contact plane, and the upper folding component 44 corresponds to the edge of the top end of the annular support ring 50 that extends out of the contact plane. The two can ensure that the two protruding edges are folded at the same time under the condition of one-time assembly of the annular support ring 50, thereby improving production efficiency.

[0022] In this embodiment, the driving structure 47 may include a lead screw and a driving motor to ensure the movement accuracy of the sliding frame 41. The lead screw can be spirally connected to the nut part set at the bottom of the sliding frame 41, and the lead screw can be rotatably set on a fixed block set on the mounting platform 11, and the driving motor is connected to the lead screw power.

[0023] In some embodiments, the lower hem assembly 43 may be configured as follows: Figures 5 to 7 See the structure shown. Figures 5 to 7 The lower folding assembly 43 includes a lower slide seat 431 and a lower bending roller 432. The lower slide seat 431 is slidably connected to the slide frame 41 and is connected to the lower telescopic structure 45. The lower bending roller 432 is rotatably arranged at the end of the lower slide seat 431 close to the tensioning part, and the lower bending roller 432 is one of the bending parts.

[0024] The lower telescopic structure 45 drives the lower sliding seat 431 to move horizontally, which can ensure that the bending roller moves below the tensioning part to below the pressure roller 42, so as to achieve the bending of the protruding edge of the bottom end of the annular support ring 50.

[0025] The lower bending roller 432 may be a truncated cone shaped structure, and the axis is inclined upward, see Figure 5 .

[0026] In some embodiments, the upper hem assembly 44 may be configured as follows: Figures 5 to 7 See the structure shown. Figures 5 to 7 The upper folding assembly 44 includes an upper slide 441, a flip plate 442, an upper bending roller 443, a sliding limit rod 444, a spring 445 and a fixed wedge 446. The upper slide 441 is slidably connected to the slide frame 41 and is connected to the upper telescopic structure 46. The upper slide 441 has a front end arranged close to the tensioning part and a rear end arranged away from the tensioning part. The flip plate 442 has a head end and a tail end. The flip plate 442 is rotatably arranged in the notch 447 of the upper slide 441. The transfer shaft of the flip plate 442 is located between the head end and the tail end, and the axis is arranged perpendicular to the sliding direction of the upper slide 441. The head end of the flip plate 442 has a tendency to continuously pitch and flip upward. The upper bending roller 443 is rotatably arranged at the head end of the flip plate 442 to pitch and rotate under the drive of the flip plate 442. The upper bending roller 443 is one of the bending parts. The sliding limit rod 444 is slidably arranged on the upper slide 441 along the sliding direction of the upper slide 441. A limit block that can be extended vertically is arranged at the top of the sliding limit rod 444. The limit block can be engaged with the avoidance opening arranged at the rear end of the flip plate 442. The spring 445 is arranged on the upper slide 441 and can bounce the sliding limit rod 444 so that the sliding limit rod 444 has a tendency to continuously move toward the front end of the upper slide 441. The fixed wedge block 446 is fixed on the slide frame 41, extends into the notch 447, and corresponds to the limit block.

[0027] When the upper slide 441 moves to the limit position close to the tensioning part, the sliding limit rod 444 is located at the rear end of the flip plate 442 and is clamped with the flip plate 442, and the flip plate 442 remains horizontal. When the upper slide 441 moves to the limit position away from the tensioning part, the sliding limit rod 444 is squeezed by the fixed wedge 446 to release the clamping connection with the flip plate 442, and the sliding limit rod 444 is pushed to the head end of the flip plate 442 by the spring 445, and the head end of the flip plate 442 pitches upward.

[0028] After the formed annular support ring 50 is removed from the tensioning part, the annular support ring 50 to be bent needs to be assembled to the tensioning part. The upper bending roller 443 is close to the contact plane at the top of the tensioning part. Therefore, after the annular support ring 50 is assembled to the tensioning part, the upper bending roller 443 cannot move to the top of the tensioning part due to travel interference.

[0029] The upper folding component 44 provided in this embodiment can effectively avoid the above problems. The specific working process thereof is as follows. Figure 7 At this time, the upper bending roller 443 is located above the contact plane at the top of the tensioning part, the flip plate 442 is arranged horizontally, and the sliding limit rod 444 below the flip plate 442 is connected with the avoidance opening at the rear end of the flip plate 442 through the limit block, and the sliding limit rod 444 is between the adapter shaft and the rear end of the flip plate 442 at this time, and the flip plate 442 cannot rotate. As the lower telescopic structure 45 drives the lower sliding seat 431 to move away from the tensioning part, the lower sliding seat 431 also drives the flip plate 442 to move synchronously, and then drives the sliding limit rod 444 to move synchronously, so as to realize the folding of the top edge of the annular support ring 50. When the upper bending roller moves to the top of the pressure roller 42 and completes the folding work of the annular support ring 50, you can refer to Figure 4 , the fixed wedge block 446 will touch the limit block at the top of the sliding limit rod 444, and through the contact of the inclined surface, the limit block will be pressed down to the inside of the sliding limit rod 444. At this time, the sliding limit rod 444 is pushed by the spring 445 and will move to the position between the adapter shaft and the head end of the flip plate 442. The flip plate 442 is not limited at this time. Under the action of the torsion spring connected to the adapter shaft, the head end will drive the upper bending roller 443 to pitch and flip upward. The annular support ring 50 that has been bent can then be disassembled, and the annular support ring 50 to be folded can be assembled. After the annular support ring 50 to be folded is assembled, the upper slide seat 441 is pushed by the upper telescopic structure 46 to move close to the tensioning part, which involves the fixed position of the sliding limit rod 444, and it will move relative to the flip plate 442. When the sliding limit rod 444 moves from the adapter shaft to the tail end of the flip plate 442, it can be seen Figure 5After the flip plate 442 is pushed by the sliding limit rod 444, the head end will pitch and rotate downward, and the upper bending roller 443 will jump over the top of the annular support ring 50 to be folded, until the flip plate 442 is set horizontally, and the limit block of the sliding limit rod 444 is engaged with the avoidance opening at the rear end of the flip plate 442.

[0030] The upper folding assembly 44 is driven only by an upper telescopic structure 46, so that when the upper slide 441 moves close to the tensioning part, the upper bending roller 443 jumps over the annular support ring 50 to be folded, avoiding interference in the stroke and ensuring the feeding of the annular support ring 50. In addition, when moving away from the tensioning part, the upper bending roller 443 can stably bend the edge of the top of the annular support ring 50, which can effectively ensure the improvement of the folding efficiency of the annular support ring 50, and has strong practicality.

[0031] It should be noted that the tip of the flip plate 442 has a tendency to rotate upward continuously, which can be achieved by a torsion spring provided on the adapter shaft. This technology is well known to those skilled in the art and will not be described in detail here. In addition, regarding the setting of a limit block on the sliding limit rod 444, a sliding cavity for the limit block to slide can be provided on the sliding limit rod 444, the top of the limit block extends out of the sliding cavity, and an elastic member is provided at the bottom. This technology is a conventional setting.

[0032] In this embodiment, a sliding cavity for the sliding limit rod 444 to slide is provided on the upper sliding seat 441, and the number of the springs 445 can be set to be multiple to ensure the stability of sliding.

[0033] It should be noted that the upper bending roller 443 may have the same specifications as the lower bending roller 432. When the flip plate 442 is pitched and rotated to a horizontal setting, the axis of the upper bending roller 443 may be set obliquely downward to form symmetry with the lower bending roller 432.

[0034] In some embodiments, the upper hem assembly 44 may be configured as follows: Figures 5 to 7 See the structure shown. Figures 5 to 7 The upper folding assembly 44 also includes a limiting cross bar 448, which is located at the end of the upper slide 441 close to the tensioning portion, and can limit the flip plate 442 that is flipped downward in pitch, so that the flip plate 442 is set horizontally.

[0035] The setting of the cross bar can ensure that after the tip end of the flip plate 442 is pitched downward, the maximum position is that the flip plate 442 is set horizontally, as shown in FIG. Figure 7 .

[0036] In some embodiments, the sliding limit rod 444 can be used as follows: Figures 5 to 7 See the structure shown. Figures 5 to 7The two ends of the sliding limit rod 444 extend out of the upper sliding seat 441 respectively, and are slidably connected to the sliding grooves 411 arranged on both sides of the sliding frame 41 respectively.

[0037] The sliding limit rod 444 is slidably connected to the sliding cavity set on the upper slide seat 441, but the sliding limit rod 444 has an extreme position during the process of moving close to the tensioning part. The sliding grooves 411 on both sides of the sliding frame 41 can ensure that the extreme position of the sliding limit rod 444 is constrained, thereby ensuring that the sliding limit rod 444 moves between the two sides of the connecting shaft of the flip plate 442, thereby constraining the flip plate 442, or releasing the constraint on the flip plate 442.

[0038] In some embodiments, the tensioning assembly 20 may be configured as follows: Figure 4 See the structure shown. Figure 4 The tensioning assembly 20 includes a vertical rotating drum 21, a rotating disk 22, a driver 26, a sector disk 23, a spring ring 24 and a vertical driving member 25. The vertical rotating drum 21 is rotatably arranged on the frame 10, and the top end extends out of the mounting platform 11. The rotating disk 22 is coaxially fixed to the top end of the vertical rotating drum 21. The driver 26 is fixed on the frame 10 and is connected to the vertical rotating drum 21 in power. There are a plurality of sector disks 23, each of which is arranged on the rotating disk 22 in an annular manner around the axis of the rotating disk 22, and each of the sector disks 23 is connected to the rotating disk 22 in a radial direction of the rotating disk 22. The sector disks 23 are combined to form a tensioning portion. The spring ring 24 is sleeved on the annular surface formed by the combination of the sector disks 23. The vertical driving member 25 is fixed on the frame 10 and connected to each sector disk 23 , and can drive each sector disk 23 to move outward to fix the annular support ring 50 erected on the support structure 30 .

[0039] The vertical rotating drum 21 and the rotating disk 22 can be ensured to rotate under the drive of the driver 26, and then the sector disks 23 can be driven to rotate, and then the annular support ring 50 can be driven to rotate, so as to ensure the folding effect. The spring ring 24 can ensure that after the bending is completed and the vertical driving member 25 releases the limit of each sector disk 23, each sector disk 23 is pulled to move inward along the radial direction of the rotating disk 22, so as to facilitate the placement and removal of the annular support ring 50.

[0040] This structure can ensure that the annular support ring 50 is supported and fixed, and ensure the folding effect of the annular support ring 50.

[0041] In this embodiment, the driver 26 and the vertical drum 21 can be connected via gears.

[0042] In this embodiment, an arc-shaped groove for accommodating the spring ring 24 may be provided on the arc-shaped surface of each sector disk 23 to prevent the spring ring 24 from contacting the annular support ring 50 .

[0043] In this embodiment, a plurality of long slides are provided on the turntable 22, each of which is arranged along the radial direction of the turntable 22 and corresponds one-to-one to each sector disk 23. Each sector disk 23 can be slidably connected to the corresponding long slide by bolts.

[0044] In some embodiments, the vertical drive member 25 may be configured as follows: Figure 4 See the structure shown. Figure 4 The vertical driving member 25 includes a vertical telescopic structure 251, a pull rod 252 and a push plate 253. The vertical telescopic structure 251 is located below the vertical rotating drum 21 and has a telescopic end that can move vertically. The pull rod 252 is vertically arranged, with the bottom end rotatably connected to the telescopic end of the vertical telescopic structure 251, and the top end passes through the vertical rotating drum 21 and then extends out. The push plate 253 is located at the top of each sector disk 23 and is connected to the pull rod 252. The bottom of the push plate 253 is provided with a conical surface that can adapt to each sector disk 23.

[0045] The pull rod 252 contacts each sector disk 23 through the push plate 253. After the pull rod 252 pulls the push plate 253 downward, each sector disk 23 can be pushed outward through the conical surface, so that each sector disk 23 props up the annular support ring 50. At this time, the pull rod 252 will rotate synchronously with the vertical rotating drum 21, so that the pull rod 252 is rotatably connected to the telescopic end of the vertical telescopic structure 251, which can ensure that the vertical telescopic structure 251 is set statically, and a thrust bearing can be used specifically.

[0046] In some embodiments, the support structure 30 may be formed as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 Each supporting structure 30 includes a fixed upright pole 31, a cylinder 32 and a support plate 33. The cylinder 32 is fixed on the fixed upright pole 31 and has a telescopic end extending upward. The support plate 33 is horizontally arranged on the telescopic end of the cylinder 32.

[0047] The cylinder 32 can ensure that the height of the support plate 33 can be adjusted, thereby adapting to annular support rings 50 of different specifications and enhancing adaptability.

[0048] In some embodiments, see Figure 3 The double-edge folding device for the annular support ring also includes a grinding assembly 60, which may include a sliding base 61 slidably connected to the guide rail on the mounting platform 11, an adjustment structure 62 for driving the sliding base 61 to move radially along the tensioning portion, and a cutting tool 63 disposed on the sliding base 61.
