They have the functions of shock absorption, waterproofing, dustproofing, sound insulation, decoration, etc., which can improve the comfort of driving experience and protect the car body. The automobile sealing strip frame is a structure used to support and fix the automobile sealing strip. It is mainly made of metal or other rigid materials and is used to enhance the structural strength and durability of the sealing strip.

[0003] In the prior art, the sealing strip skeleton is composed of fins and main ribs. During the production process, the fins are often placed evenly along the length direction of the main ribs through a loading assembly, and then subsequent processing is performed.

[0004] However, since the wings are often packed in boxes after production, the directions of the wings are different, and the directions of the wings need to be additionally combed to make them in the same direction, which greatly delays the production efficiency of the sealing strip skeleton.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention uses the structure of the feeding component and the rotating ring, especially the convex structure of the sorting groove, so that after the U-shaped wing is put into the feeding component and falls into the sorting groove, it can only open to the right or to the left. When it opens to the right, the rotating ring rotates 270°, and the U-shaped wing slides to the bottom of the convex under the action of gravity and slides to the discharge port. When it opens to the left, the rotating ring rotates 90°. At this time, the U-shaped wing does not engage with the convex, and is directly fed along the slide groove, so that a large number of disorderly U-shaped winglets are fed in the same direction, saving time for sorting the U-shaped winglets and improving the production efficiency of the automotive sealing strip skeleton;

[0023] 2. Through the synchronous rotation structure of the rotating ring and the fixed ring, in conjunction with the convex block on the surface of the fixed ring, when the fixed ring rotates, it will periodically drive the block to slide in the front-back direction, so that the propulsion assembly rotates, and under the elastic force of the third spring, the propulsion assembly and the rack are controlled to reset, so that the propulsion assembly swings periodically. Under the connection of the rack, the slide is controlled to slide periodically, and each sliding distance is the same. Under the condition that the U-shaped wing blanking frequency is controlled to be consistent with the slide frequency, the spacing of each U-shaped wing on the main rib plate is exactly the same, which is convenient for the production of the automotive sealing strip skeleton;

[0024] 3. Through the sliding structure of the telescopic assembly and the push rod, in conjunction with the trapezoidal structure of the limit block, the push rod pushes the slide to move horizontally after contacting the right-angled side of the limit block. During the process of resetting the rack, the push rod contacts the hypotenuse of the limit block, and the force generated between the two is decomposed by the hypotenuse into forces in the front and rear directions and left and right directions. The forces in the left and right directions control the contraction of the push rod, so that the push rod can pass through the limit block in the reverse direction. The forces in the front and rear directions are offset by the static friction between the slide and the guide rail to prevent the slide from sliding in the reverse direction, causing deviations in the distance of each movement of the main rib plate, resulting in deviations in the distribution of the U-shaped wing on the main rib plate, which ultimately affects the strength of the automotive sealing strip skeleton.

DETAILED DESCRIPTION

[0037] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0038] See also Figures 1 to 11 The present invention provides a technical solution: a feeding device for producing an automobile sealing strip skeleton, comprising a base 1, a feeding assembly 2 is installed on one side of the base 1, a feeding port 25 is arranged above the feeding assembly 2, and a discharge port 26 is arranged below the feeding assembly 2;

[0039] The U-shaped fins are placed in the loading assembly 2 through the feed opening 25 , and are transported downward through the discharge opening 26 .

[0040] The discharge port 26 is provided with a limit assembly, and the discharge port 26 discharges materials periodically through the limit assembly;

[0041] Through the limit assembly structure on the discharge port 26, the U-shaped fins entering the discharge port 26 are timed to be released during the downward movement, so that the U-shaped fins are periodically circulated downward at the discharge port 26;

[0042] At the same time, a turning mechanism can be provided on the discharge port 26 so that the U-shaped wing can turn over and fall onto the main rib plate.

[0043] A rotating ring 3, which is arranged above the base 1 and is rotatably connected to the base 1, and the rotating ring 3 turns over the U-shaped fins entering the rotating ring 3 so that all the U-shaped fins are in the same direction when unloading;

[0044] By rotating the rotating ring 3 in the feeding assembly 2 , the U-shaped fins entering the feeding assembly 2 are selectively turned over so that the U-shaped fins maintain the same direction after entering the discharge port 26 .

[0045] A propulsion assembly 5, wherein the propulsion assembly 5 is disposed below the feeding assembly 2, and the propulsion assembly 5 reciprocates following the rotation of the rotating ring 3, and periodically pushes the slide 9 in one direction;

[0046] The clamping assembly 10 is installed above the slide 9. The main rib plate is clamped and installed on the clamping assembly 10. When the slide 9 moves, the main rib plate is driven to move horizontally.

[0047] The main rib plate is clamped and fixed above the slide 9 by the structure of the clamping assembly 10, so that the movement of the slide 9 drives the main rib plate to move;

[0048] During the rotation of the rotating ring 3, the propulsion assembly 5 is driven to swing back and forth, so that the propulsion assembly 5 can periodically push the slide 9 in one direction for a certain distance, and cooperate with the limiting assembly of the discharge port 26 to make the U-shaped winglets evenly arranged on the main rib plate.

[0049] A bracket 21 is provided at the bottom of the feeding component 2, and the bracket 21 is installed on the base 1 by bolts. A cavity is provided inside the feeding component 2, and a circulation rack 23 is fixedly connected to the axial part of the feeding component 2. An annular groove is provided between the circulation rack 23 and the inner wall of the cavity of the feeding component 2. The rotating ring 3 is provided in the annular groove, and a gear 22 is provided in the circulation rack 23. The gear 22 is connected to the motor through a shaft. A first gear ring 31 is fixedly connected to the inner wall of the rotating ring 3, and the upper part of the gear 22 meshes with the first gear ring 31 for transmission.

[0050] After the motor is started, the gear 22 is driven to rotate in the circulation rack 23 . Since the gear 22 is meshed with the first gear ring 31 on the inner wall of the rotating ring 3 , the rotation of the gear 22 drives the rotating ring 3 to rotate in the feeding assembly 2 .

[0051] A slide groove 24 is provided in the middle of the circulation rack 23, and the slide groove 24 is arranged in an inclined shape. Four sorting grooves 32 are provided on the rotating ring 3, and a protrusion is provided in the clockwise direction of the sorting grooves 32. The sorting grooves 32 are evenly distributed on the rotating ring 3, and the sorting grooves 32 are arranged in a U-shape. The direction of each sorting groove 32 is the clockwise direction of the rotating ring 3. The feed port 25 and the discharge port 26 both penetrate into the loading component 2, and the feed port 25 is perpendicular to the slide groove 24, and the discharge port 26 is arranged on the extension line of the lower end of the slide groove 24.

[0052] After the U-shaped wing falls from the feed port 25 into the finishing tank 32 above, two situations may occur, one of which is that the U-shaped wing opens to the right, and the other is that the U-shaped wing opens to the left;

[0053] When the U-shaped wing opens to the right, when the rotating ring 3 rotates 90° clockwise, the opening of the U-shaped wing engages with the protrusion in the sorting groove 32 under the action of gravity. At this time, after the sorting groove 32 is connected with the slide groove 24, the U-shaped wing cannot move along the slide groove 24 to the discharge port 26. After the rotating ring 3 continues to rotate 180°, the sorting groove 32 is directly connected with the discharge port 26, and the protrusion of the sorting groove 32 is located above it. Under the action of gravity, the U-shaped wing slides from the bottom of the protrusion of the sorting groove 32 into the discharge port 26, and the U-shaped wing opens upward;

[0054] When the U-shaped wing opens to the left, the rotating ring 3 rotates 90° clockwise. At this time, the U-shaped wing opens upward and cannot engage with the protrusion, so that the U-shaped wing slides along the slide groove 24 toward the discharge port 26.

[0055] A fixing ring 4 is fixedly connected to one side of the rotating ring 3, and the fixing ring 4 rotates coaxially with the rotating ring 3. A baffle 42 is fixedly connected to one end of the fixing ring 4 away from the rotating ring 3. A protrusion 41 is fixedly connected to the side wall of the fixing ring 4 in the direction toward the rotating ring 3, and the side of the protrusion 41 facing the rotation direction of the fixing ring 4 is set as a hypotenuse. The propulsion assembly 5 is arranged below the fixing ring 4, and the propulsion assembly 5 includes a stop block 52, which abuts against the lower side wall of the fixing ring 4, and the hypotenuse of the protrusion 41 abuts against the side of the stop block 52.

[0056] During the rotation of the rotating ring 3, the fixed ring 4 is driven to rotate in the same direction, and since the stop block 52 abuts against the lower side wall of the fixed ring 4, during the rotation of the fixed ring 4, the oblique edge of the protrusion 41 will squeeze the stop block 52 in the direction of the baffle 42, and the structure of the baffle 42 prevents the stop block 52 from falling off the side wall of the fixed ring 4.

[0057] A first connecting rod 51 is fixedly connected to the bottom of the stop block 52, and the lower end of the first connecting rod 51 is fixedly connected to one end of the propulsion assembly 5. A lifting plate 6 is provided below the propulsion assembly 5, and the middle part of the propulsion assembly 5 is rotatably connected to the lifting plate 6 through an axis, and first sliding columns 61 are fixedly connected to the two sides of the bottom of the lifting plate 6 respectively, and a first fixed column 62 is sleeved below the first sliding column 61. The first sliding column 61 is vertically slidably connected to the first fixed column 62, and the lower end of the first fixed column 62 is fixedly connected to the top of the base 1. A first spring 63 is provided in the first fixed column 62, and the upper end of the first spring 63 is fixedly connected to the bottom of the first sliding column 61, and the lower end of the first spring 63 is fixedly connected to the bottom inner wall of the first fixed column 62.

[0058] In the absence of external force, the elastic force of the first spring 63 causes the first sliding column 61 to slide upward along the first fixed column 62, driving the lifting plate 6 to slide vertically upward, so that the propulsion assembly 5 always has an upward movement trend, so that the stop block 52 can resist the lower side wall of the fixing ring 4.

[0059] One end of the propulsion assembly 5 away from the first connecting rod 51 is fixedly connected to the second gear ring 53, and a rack 7 is arranged on the side of the second gear ring 53 away from the propulsion assembly 5. The rack 7 is meshed with the second gear ring 53 for transmission, and a ring 71 is fixedly connected below the rack 7. The ring 71 is sleeved on the fixed rod 8, and the ring 71 is horizontally slidably connected to the fixed rod 8. The two ends of the fixed rod 8 are respectively fixedly connected to connecting plates 81. The fixed rod 8 is sleeved with a third spring 82 in the opposite direction of the movement of the ring 71. One end of the third spring 82 is fixedly connected to the ring 71, and the other end of the third spring 82 is fixedly connected to the connecting plate 81.

[0060] Under the elastic force of the third spring 82, the ring 71 always tends to move in the opposite direction of the sliding of the rack 7. After the propulsion assembly 5 rotates and the protrusion 41 passes through the stop block 52, the rack 7 is driven to reset, that is, the propulsion assembly 5 rotates in the opposite direction to the initial state, so that the propulsion assembly 5 performs periodic reciprocating swings.

[0061] A telescopic component 72 is fixedly connected to the outer wall of the ring 71 on the side away from the feeding component 2, and a push rod 73 is horizontally slidably connected to the outer end of the telescopic component 72. A second spring 74 is provided on the inner side of the push rod 73, and the two ends of the second spring 74 are respectively fixedly connected to the push rod 73 and the inner wall of the telescopic component 72. A connecting rope 75 is provided on the inner side of the second spring 74. The connecting rope 75 passes through the upper side of the ring 71 and the rack 7, and the upper end of the connecting rope 75 passes through the rack 7. The upper end of the connecting rope 75 is fixedly connected to a pulling block 76.

[0062] A guide rail 11 is fixedly connected to the top of the base 1, and the slide 9 is sleeved on the guide rail 11. The slide 9 is horizontally slidably connected to the guide rail 11, and the static friction between the slide 9 and the guide rail 11 is greater than the decomposed front-rear direction force between the push rod 73 and the limit block 91. A plurality of evenly distributed limit blocks 91 are horizontally arranged on the side of the slide 9 facing the rack 7. The limit blocks 91 and the push rod 73 are located at the same height, and each of the limit blocks 91 is set to a trapezoid, and the end of the push rod 73 is set to the center of a circle. After the end of the push rod 73 contacts the hypotenuse of the limit block 91, it shrinks into the telescopic assembly 72, and the end of the push rod 73 abuts against the right-angle side of the limit block 91.

[0063] When the rack 7 slides in the direction of the right-angled side of the limit block 91, the push rod 73 pushes the right-angled side of the limit block 91 horizontally to move, and after the rack 7 rotates to the maximum distance, that is, after the protrusion 41 completely passes the stop block 52, the rack 7 rotates in the direction until it is reset under the elastic force of the third spring 82. In this process, the push rod 73 contacts the hypotenuse of the limit block 91, and the hypotenuse of the limit block 91 squeezes the push rod 73 into the telescopic assembly 72, causing the push rod 73 to contract, and the contact between the two generates an interaction force. The force in the left and right directions is greater than the elastic force of the second spring 74, and the force in the front and rear directions will cause the limit block 91 to drive the slide 9 to move in the opposite direction. However, since the static friction between the slide 9 and the guide rail 11 is greater than the value of the force, the slide 9 will not slide in the opposite direction.

[0064] Each time the propulsion assembly 5 swings, the distance that the slide 9 moves is exactly the same. Cooperating with the limit assembly structure on the discharge port 26, a U-shaped wing is dropped after the slide 9 moves a certain distance, so that the U-shaped wing is evenly arranged on the main rib plate.

[0065] The clamping assembly 10 is respectively installed at the two ends above the slide 9, and the clamping assembly 10 includes a second connecting rod 104 fixedly connected to the upper surface of the slide 9, a lower clamp plate 101 is fixedly connected above the second connecting rod 104, an upper clamp plate 102 is slidably connected above the lower clamp plate 101, and anti-slip pads 103 are respectively provided on the facing sides of the upper clamp plate 102 and the lower clamp plate 101, and the upper clamp plate 102 and the lower clamp plate 101 together clamp and fix the two ends of the main rib plate through the anti-slip pads 103.

[0066] A second sliding column 105 is fixedly connected to the lower side of the upper clamping plate 102, and the second sliding column 105 is sleeved on the top of the second fixed column 106. The second fixed column 106 is vertically slidably connected to the second sliding column 105, and the lower end of the second fixed column 106 is fixedly connected to the top of the lower clamping plate 101. A fourth spring 107 is arranged between the second sliding column 105 and the second fixed column 106, and the upper and lower ends of the fourth spring 107 are fixedly connected to the second sliding column 105 and the second fixed column 106 respectively.

[0067] Under the elastic force of the fourth spring 107, the second sliding column 105 slides toward the second fixed column 106, that is, the upper clamp 102 always has a tendency to slide toward the lower clamp 101. After the main rib is placed between the upper clamp 102 and the lower clamp 101, under the elastic force of the fourth spring 107, the upper clamp 102 and the lower clamp 101 clamp the main rib together. After the two groups of clamping assemblies 10 clamp the two ends of the main rib, the main rib can move horizontally following the sliding of the slide 9, and the friction force of the upper clamp 102 and the lower clamp 101 on the main rib is increased through the structure of the anti-slip pad 103 to prevent the clamping from loosening and falling off.
