Description

Technical Field

[0001] The utility model relates to the technical field of fuel filter, in particular to a production technology in the production process of the fuel filter. Background Art

[0002] The fuel filter includes a filter element. In the production process of the fuel filter, assembling the filter element is an essential process.

[0003] The filter element comprises a cylindrical filter layer, an upper end cap is bonded to the upper end of the cylindrical filter layer, and a lower end cap is bonded to the lower end of the cylindrical filter layer.

[0004] When assembling the filter element, it is necessary to tie a rubber band on the middle and lower part of the filter layer, and then bond the upper end cover to the upper end of the filter layer; if the rubber band is not tied, the middle and lower part of the filter layer will easily open and become a bell mouth due to the loss of restraint after bonding the upper end cover and before bonding the lower end cover (at this stage, the filter element needs to be moved from the upper end cover assembly position to the lower end cover assembly position). After bonding the upper end cover, it can restrain the upper end of the filter layer. When bonding the lower end cover, the staff needs to remove the rubber band first, and then bond the end cover. Removing the rubber band is cumbersome and affects production efficiency, and the removed rubber band is easy to bounce on the operating table, affecting the cleanliness of the site and making it difficult to clean; when the rubber band is not removed thoroughly, the rubber band sticks to the filter element and causes quality risks. Therefore, bonding the lower end cover becomes a bottleneck process in the assembly of the filter element, and the assembly time takes 4.2 seconds.

[0005] The design idea of ​​the utility model is to design a fuel filter element curing device, cooperate with the annular filter element assembly line, after the upper end cover is bonded, the fuel filter element curing device is used to restrain the filter layer from opening into a trumpet shape during the transfer of the filter layer (from the upper end cover assembly position to the lower end cover assembly position), and there is no need to remove the rubber band when assembling the lower end cover, and there will be no various disadvantages caused by the rubber band. Utility Model Content

[0006] The utility model aims to provide a fuel filter element curing device, which is used to constrain the filter layer to prevent it from opening during the process of moving the filter layer from the upper end cover assembly position to the lower end cover assembly position, thereby eliminating the disadvantages of using rubber bands to constrain the filter layer.

[0007] To achieve the above-mentioned purpose, the fuel filter element curing device of the utility model is used for a filter element assembly production line, the filter element assembly production line includes a lower annular slide and an upper slide, the upper slide includes a descending slide and an ascending slide, the descending slide and the ascending slide both include a horizontal part and an inclined part connected to the horizontal part;

[0008] It includes a trolley bottom plate, which is connected downwardly to a plurality of lower pulleys, each of which is used for slidingly cooperating with the lower annular slideway; the trolley bottom plate is used for placing the filter element being processed;

[0009] A left vertical rod and a right vertical rod are connected upwardly from the middle of the bottom plate of the trolley, and an arc-shaped baffle plate with a circular arc horizontal cross section is connected between the left vertical rod and the right vertical rod, and the inner diameter of the arc-shaped baffle plate matches the outer diameter of the filter layer;

[0010] A sliding hanger is provided above the arc-shaped baffle, a suspension pulley for hanging on an upward slideway or a downward slideway is provided on the top of the sliding hanger, and a shaped pressing groove is connected to the bottom end of the sliding hanger, the shaped pressing groove opens downward and matches the filter layer of the filter element;

[0011] When the suspension pulley is hung on the horizontal part of the ascending slideway or the descending slideway, the molded pressing groove is higher than the filter element, and when the suspension pulley runs to the bottom of the inclined part of the ascending slideway or the descending slideway, the molded pressing groove is pressed on the filter element.

[0012] The arc baffle is located at the middle of the height of the left vertical rod and the right vertical rod. A lower baffle is also provided on the bottom plate of the trolley, and the lower baffle is located on the vertical projection surface of the arc baffle.

[0013] Two sets of shaped pressing grooves, arc-shaped baffles and lower baffles are symmetrically arranged on the left and right, and each set of shaped pressing grooves, arc-shaped baffles and lower baffles is used to position and restrain a filter element in the assembly process.

[0014] The shaped crimping groove is located between the left vertical bar and the right vertical bar.

[0015] The utility model has the following advantages:

[0016] The utility model uses the shaped pressing groove to constrain the filter layer from top to bottom until the axial pressing and directly constrains the bottom end of the filter layer (the filter layer is placed upside down on the bottom plate of the trolley, so the top end is the bottom end of the filter layer) circumferentially, ensuring that the filter layer will not open into a trumpet shape when it is transported from the upper end cover assembly position to the lower end cover assembly position. The utility model uses the arc baffle and the lower baffle to play an auxiliary circumferential constraint role on the filter layer in transportation.

[0017] Since there is no need to tie the rubber band, there is no need to remove the rubber band when bonding the lower end cover, which improves the efficiency of bonding the lower end cover. The average time for bonding the lower end cover is shortened from 4.2 seconds to 3.6 seconds, and the output of the filter element line is increased from 6160 pieces to 6800 pieces, an increase of 640 pieces. In addition, the potential quality accident of the rubber band sticking to the filter element is eliminated, and the problem of the rubber band bouncing on the operating table affecting the cleanliness and requiring cleaning when removing the rubber band is also eliminated.

[0018] The arc baffle has a limited height, which saves materials, and cooperates with the lower baffle to play a good role in circumferentially constraining the filter layer. Two sets of shaped crimping grooves, arc baffles and lower baffles enable the utility model to transport two filter elements in assembly at one time, improving the transport efficiency, and each filter element can be easily pushed into the arc baffle and taken out horizontally.

[0024] like Figures 1 to 5 As shown, the fuel filter element curing device of the utility model is used in the end cover bonding process of the filter element assembly production line, to be precise, it is used after the upper end cover is bonded and before the lower end cover is bonded. The filter element assembly production line includes a lower annular slide 1 and an upper slide, the upper slide includes a descending slide 2 and an ascending slide 3, and the descending slide 2 and the ascending slide 3 both include a horizontal part and an inclined part connected to the horizontal part;

[0025] The fuel filter element curing device comprises a trolley bottom plate 4, which is downwardly connected to a plurality of lower pulleys 5, each of which is used for slidingly cooperating with the lower annular slideway 1; the trolley bottom plate 4 is used for placing the filter element (filter layer and upper end cover) being processed;

[0026] A left vertical rod 6 and a right vertical rod 7 are connected upwardly from the middle of the bottom plate 4 of the trolley, and an arc-shaped baffle plate 8 with a circular arc horizontal cross section is connected between the left vertical rod 6 and the right vertical rod 7, and the inner diameter of the arc-shaped baffle plate 8 matches the outer diameter of the filter layer;

[0027] A sliding hanger 9 is provided above the arc baffle 8, a suspension pulley 10 for hanging on the upward slideway 3 or the downward slideway 2 is provided on the top of the sliding hanger 9, and a shaped pressing groove 11 is connected to the bottom end of the sliding hanger 9, the shaped pressing groove 11 opens downward and matches the filter layer of the filter element;

[0028] When the suspension pulley 10 is hung on the horizontal part of the ascending slide 3 or the descending slide 2, the forming press-fitting groove 11 is higher than the filter element. When the suspension pulley 10 runs to the bottom of the inclined part of the ascending slide 3 or the descending slide 2, the forming press-fitting groove 11 is pressed on the filter element (at this time, the bottom end of the filter element is set upward, the top end of the filter element is placed downward on the bottom plate 4 of the trolley, and the bottom end of the filter element is inserted into the forming press-fitting groove 11).

[0029] The utility model uses the shaped crimping groove 11 to constrain the filter layer from top to bottom until the axial crimping action and directly constrains the bottom end of the filter layer (the filter layer is placed upside down on the bottom plate 4 of the trolley, so the top end is the bottom end of the filter layer) circumferentially, ensuring that the filter layer will not open into a trumpet shape when it is transported from the upper end cover assembly position to the lower end cover assembly position. The utility model uses the arc baffle 8 and the lower baffle to play an auxiliary circumferential constraint role on the filter layer in transit.

[0030] Since there is no need to tie the rubber band, there is no need to remove the rubber band when bonding the lower end cover, which improves the efficiency of bonding the lower end cover. The average time for bonding the lower end cover is shortened from 4.2 seconds to 3.6 seconds, and the output of the filter element line is increased from 6160 pieces to 6800 pieces, an increase of 640 pieces. In addition, the potential quality accident of the rubber band sticking to the filter element is eliminated, and the problem of the rubber band bouncing on the operating table affecting the cleanliness and requiring cleaning when removing the rubber band is also eliminated.

[0031] The arc baffle 8 is located at the middle of the height of the left vertical rod 6 and the right vertical rod 7. A lower baffle 12 is also provided on the trolley bottom plate 4. The lower baffle 12 is located on the vertical projection surface of the arc baffle 8 and is preferably flush with the vertical baffle 13 described below.

[0032] Two sets of the shaping and crimping grooves 11, arc-shaped baffles 8 and lower baffles 12 are symmetrically arranged on the left and right sides, and each set of the shaping and crimping grooves 11, arc-shaped baffles 8 and lower baffles 12 is used to position and constrain a filter element (filter layer) in the assembly process.

[0033] The arc baffle 8 has a limited height, which saves materials, and cooperates with the lower baffle 12 to play a good role in circumferentially constraining the filter layer. The two sets of shaped crimping grooves 11, the arc baffle 8 and the lower baffle 12 enable the utility model to transport two filter elements in assembly at one time, improve the transport efficiency, and each filter element can be easily pushed into the arc baffle 8 and taken out horizontally.

[0034] The shaped crimping groove 11 is located between the left vertical rod 6 and the right vertical rod 7 to ensure that the filter layer positioning structure is effective.

[0035] A vertical baffle 13 is connected downwardly in the middle of the arc-shaped baffle 8, and the vertical baffle 13 is connected downwardly to the bottom plate 4 of the trolley. The vertical baffle 13 and the arc-shaped baffle 8 both play a role in preventing the filter element from being separated from the bottom plate 4 of the trolley.

[0036] The bonding position of the upper end cover is located at the descending slide 2, and the bonding position of the lower end cover is located at the ascending slide 3.

[0037] When the staff at the upper end cover bonding position bonds the upper end cover, they first bond the upper end cover on the filter layer, then turn the filter layer with the upper end cover upside down and place it on the bottom plate 4 of the trolley and push the arc baffle 8 horizontally, so that the arc baffle 8 and the lower baffle play a circumferential constraint role on the filter layer; two filter elements in the end cover bonding process can be placed on the left and right in the fuel filter element curing device of the utility model.

[0038] At this time, the trolley is pushed along the lower annular slide 1 to the upward slide 3, and the suspension pulley 10 enters the inclined part of the downward slide 2 from the horizontal part of the downward slide 2. When descending along the inclined part, under the action of gravity, the shaping and pressing groove 11 gradually presses down on the bottom end of the filter layer (the filter layer is placed upside down with the top facing down). At this time, the trolley can be moved along the lower annular slide 1 to the upward slide 3. During this transportation process, the shaping and pressing groove 11 constrains the circumferential position of the bottom end of the filter layer (the filter layer is placed upside down at this time) and constrains the filter layer axially. At the same time, the arc baffle 8 and the lower baffle play an auxiliary restraining role on the filter layer. When the trolley runs to the upward slide 3 (arrives at the lower end cover assembly position), as the suspension pulley 10 runs upward along the upward slide 3, the sliding hanger 9 gradually rises, thereby driving the shaping and pressing groove 11 to leave the filter layer upward and no longer constrain the filter layer. The staff takes the filter layer out from the bottom plate 4 of the trolley in the horizontal direction, and can bond the lower end cover without turning it up and down (because the bottom end of the filter layer is facing upward at this time). The entire (upper and lower) end cover bonding process does not require tying and removing rubber bands, which significantly improves the end cover bonding efficiency.
