Description

Technical Field

[0001] The present invention relates to the technical field of glue injection and shaping devices, and particularly to an adjustable filter element glue injection and shaping device and method. Background Art

[0002] Filter element glue injection and shaping precisely injects an adhesive into the joints of components such as the skeleton, filter media, and end caps of the filter element through special equipment. Utilizing the bonding and curing characteristics of the adhesive, the various components of the filter element form a stable overall structure.

[0003] Among them, the filter media and the skeleton need to be shaped by the adhesive first, and then the inside of the end cap is injected with glue and then assembled with the filter media and the skeleton. Injecting glue into the end cap needs to be completed by a glue injection machine.

[0004] Referring to a filter end cap glue injection machine disclosed in a patent application with a publication number of CN105289933B, by using two cylinders to do work on the upright post, driving the upright post to complete the forward and reverse rotation processes, the glue injection gun injects glue in two circles, forward and backward, on the end cap, making the end cap bond more tightly with the filter element, with better sealing performance and higher quality of the filter element; the design of the magnet in the end cap limiting device makes it more convenient to place and pick up the end cap, and the end cap is more stable during movement and will not be displaced; since the tray is adsorbed on the magnet, according to the different specifications and sizes of different parts to be injected with glue, it is possible to easily replace the matching tray, and the operation is simple and convenient. The above-mentioned end cap glue injection machine in the prior art has the following defects in actual use: 1) In the existing end cap glue injection machine, since the glue injection gun is always connected to the raw material cylinder storing the glue, the glue injection gun is always filled with glue, and some glue will drip under the action of gravity even when the glue injection gun does not perform the glue injection operation, resulting in the glue dripping on the operation table or other positions outside the filter media, which will not only cause waste of glue, but also pollute the operation table surface and the filter media; 2) Since a certain width of annular glue needs to be injected into the annular area at the bottom of the end cap inner cavity, it is required that the filter media rotates while the glue injection gun translates within the glue injection area. In this process, not only does the filter media need to rotate multiple circles to complete the glue injection operation, increasing the glue injection time, but also the movement trajectory of the glue injection gun needs to be adjusted specifically for different end caps with different widths of the glue injection area, thus increasing the operation difficulty; Therefore, the present invention proposes an adjustable filter element glue injection and shaping device and method to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an adjustable filter element glue injection and shaping device and method, which solves the problem that when the glue injection gun of the existing end cap glue injection machine does not perform the glue injection operation, some glue will also drip under the action of gravity, resulting in the glue dripping on the operating table or other positions outside the filter material. This not only causes waste of glue, but also pollutes the operating table surface and the filter material. Moreover, since a certain width of annular glue needs to be injected into the annular area at the bottom of the inner cavity of the end cap, it is required that the filter material rotates while the glue injection gun translates within the glue injection area. Not only does it take multiple rotations of the filter material to complete the glue injection operation, increasing the glue injection time, but also the movement trajectory of the glue injection gun needs to be adjusted specifically for different end caps with different widths of the glue injection area, thus increasing the operation difficulty.

The glue injection execution assembly injects a preset amount of glue into the filter element end cap; Step 3: After the glue injection is completed, take out the filter element end cap from the top of the tray assembly and place the filter element end cap to be injected with glue again; Step 4: When replacing filter element end caps of different sizes, control the distribution width of the output glue by controlling the pressure of the input glue, so as to make the glue conveying width match the glue injection width inside the filter element end cap.

[0016] The present invention provides an adjustable filter element glue injection and shaping device and method. Compared with the prior art, it has the following beneficial effects: 1. An adjustable filter element glue injection and shaping device and method. By setting up a glue injection mechanism, the glue conveying component and the glue injection execution component inside it form a linkage. The glue conveying component uses the kinetic energy of the injected glue to drive the impeller to rotate, thereby providing power for the rotation of the arc-shaped defoaming plate. It can drive the arc-shaped defoaming plate to eliminate the bubbles mixed in the glue within a larger range during rotation. Secondly, the power of the impeller rotation can also drive the glue injection execution component to rotate, enabling the glue injection execution component to drive the glue injection components at multiple positions to rotate synchronously in a circular motion during rotation. The multiple glue injection components can jointly and quickly sweep the inner annular glue injection area of the filter element end cap during rotation, so that the output glue can cover the inner annular glue injection area of the filter element end cap in a short time, greatly shortening the glue injection time for a single filter element end cap and improving the glue injection efficiency of the filter element end cap.

[0017] 2. An adjustable filter element glue injection and shaping device and method. By setting up a glue injection component, it can change the position of the release width control unit at the corresponding position by moving the blocking partition plate, so that multiple release width control units can be distributed on circumferences with different diameters, and then can perform glue injection operations on filter element end caps with different outer diameters, improving the applicable range of the release width control unit.

[0018] 3. An adjustable filter element glue injection and shaping device and method. By setting up a glue release control unit, using the lever principle, after the glue impacts the top of the support plate, the conical plug can move upward from the conical through-hole, forming a certain size of gap between the conical plug and the conical through-hole, which can provide a channel for the glue to pass through. And by controlling the size of the glue conveying pressure, the impact force acting on the support plate can be controlled, and then the height of the upward movement of the conical plug can be controlled. That is, the higher the conical plug rises, the larger the gap between the conical plug and the inner wall of the conical through-hole, and the more glue passes through per unit time. While reducing the glue injection time, it can meet the glue injection volume requirements of larger-sized filter element end caps. After reducing the glue conveying pressure, the impact force acting on the support plate can be synchronously reduced, the height of the upward movement of the conical plug decreases, the gap between the conical plug and the inner wall of the conical through-hole decreases, and the amount of glue passing through per unit time decreases, which can be applicable to the glue injection operation of smaller-sized filter element end caps.

[0019] 4. An adjustable filter element glue injection and shaping device and method. Through the first width limiting unit and the second width limiting unit, the acting force on the second horizontal inclined plate in the first width limiting unit and the second width limiting unit can be controlled by controlling the size of the glue injection pressure, and then the distance between the ends of the two horizontal plates can be controlled. That is, after increasing the glue injection pressure, the thrust acting on the second inclined plate increases, so that the two horizontal plates can be indirectly pushed away from each other, and the glue outlet width at the bottom of the glue injection head increases, achieving the effect of increasing the glue injection width. When the glue injection pressure decreases, the thrust on the second inclined plate decreases, and the two horizontal plates can move relative to each other under the action of the spring force, reducing the glue outlet width at the bottom of the glue injection head and achieving the effect of reducing the glue injection width. Thus, the purpose of quickly adjusting the glue outlet width of the glue injection head according to the glue injection width of filter element end caps of different sizes is achieved, and the adjustment process is simpler and faster.

Then, gradually slide the filter element end cap to be processed down between the inner walls of the multiple clamping plates 54 until the bottom of the filter element end cap is in contact with the top of the placement tray 51; Next, step on the foot control switch 7 to send a glue injection instruction to the control box 6. The control box 6 first controls the output end of the lifting cylinder 3 to drive the glue injection mechanism 4 to move down a preset distance through the control instruction, and then sends a glue injection instruction to the external glue pump. The glue pump quantitatively aspirates the glue in the glue storage tank within a preset time and transports it to the first glue cylinder 81 through the glue delivery pipe and the glue inlet pipe 89. The glue passes through the filter holes on the surface of the stationary arc-shaped defoaming plate 86 and then enters the glue pipe 82 along the confluence pipe 85. The defoaming blades 87 in the filter holes cut the bubbles mixed in the glue, and the flowing glue pushes the impeller 84 to rotate. At the same time, the arc-shaped defoaming plates 86 at multiple positions rotate synchronously to continue the filtering and defoaming process for the subsequent incoming glue; Next, since the bottom end of the transmission shaft 83 is fixedly connected to the bottom of the inner cavity of the second glue cylinder 91, the second glue cylinder 91 rotates while the transmission shaft 83 rotates. At the same time, the glue enters the second glue cylinder 91 through multiple glue inlet holes 95. The glue entering the second glue cylinder 91 through the glue inlet holes 95 respectively acts on the top of the support plate b2 at the corresponding positions. The support plate b2 moves downward under the action of the downward pressure. According to the lever principle, with the rotating shaft b3 as the fulcrum, the tapered plug b6 moves upward along the inner wall of the tapered through hole 982, and a gap appears between the inner wall of the tapered through hole 982 and the outer wall of the support plate b2. The glue flows into the release width control unit 983 through this gap; The glue flowing out of the second glue cylinder 91 directly acts on the inclined surface of the second inclined plate a46 and slides down along this inclined surface. Finally, the glue flows out through the gap between the two cross plates a41 and forms a ring-shaped glue with a preset width in the filter element end cap along with the rotation of the second glue cylinder 91; When it is necessary to inject glue into filter element end caps of different sizes, refer to the second scale wire groove 99 and pull the partition plates 981 at multiple positions to move along the sliding groove 96. It should be noted that the initial positions of the multiple release width control units 983 are known values, that is, the distances between the release width control units 983 are also known values. By pulling or pushing the partition plate 981 within a certain range, the positions of the release width control units 983 are changed, so that the bottom of the release width control unit 983 is just within the glue injection area at the top of the filter element end cap to be injected with glue, and the center position at the bottom of the release width control unit 983 is located on the center line of the glue injection width of the annular glue injection area. After the position adjustment of the release width control unit 983 is completed, use the fastening bolts to lock the position of the partition plate 981; When injecting glue into an annular glue injection area with different widths inside the filter element end cap, since the distance between the ends of the two cross plates a41 of the first width limiting unit a4 and the second width limiting unit a5 is a known value in the initial position, by changing the rotation speed of the glue pump, the output pressure of the glue per unit time is changed, so that the impact force of the glue acting on the inclined surface of the second inclined plate a46 is correspondingly changed. That is, when the rotation speed of the glue pump is increased, the output pressure of the glue can be increased, so that the two second inclined plates a46 are pushed to rotate relative to each other. When the second inclined plate a46 rotates, the first inclined plate a45 will push the cross plate a41 to slide along the inner wall of the long strip through groove a2, and the distance between the two cross plates a41 is increased, so that the width of the glue output per unit time is increased, and vice versa.
