Description

Technical Field

[0001] The present invention belongs to the technical field of material compounding machines, and particularly relates to a general compounding machine for automotive interior materials that prevents overflow. Background Art

[0002] In the production of automotive interior materials, a compounding machine is required to compound foam and interior materials together to form a composite material that meets the requirements of automotive interiors. For example, a Chinese patent with the publication number CN117799283B discloses a general compounding machine for automotive interior materials. However, there are some problems in the actual application of existing compounding machines for automotive interior materials: During the glue extrusion process, there is a lack of an effective control mechanism, and the residual glue will drip onto the next part of the material. The dripping position of the glue is uncertain, resulting in uneven glue dripping, and the glue may overflow from the edge of the foam. This not only causes waste of glue but also leads to inconsistent bonding strength of the composite interior materials, affecting the appearance and quality of the product. Summary of the Invention

[0003] In order to solve the problems raised in the above background art, the present invention provides a general compounding machine for automotive interior materials that prevents overflow.

[0004] The technical solution of the present invention is: a general compounding machine for automotive interior materials that prevents overflow, including a bracket. A conveyor belt is installed on the bracket. Two side plates are connected to the bracket. A compounding mechanism for compounding foam and interior layers is installed between the two side plates. A connecting frame is connected between the two side plates. A hollow glue storage column is connected to the lower part of the connecting frame. A glue inlet pipe is installed on the side of the glue storage column. An extrusion plate that slides up and down is provided inside the glue storage column. A row of glue outlet holes are evenly spaced on the bottom surface of the glue storage column. A baffle that moves left and right and is used to block the glue outlet holes is provided below the glue storage column. A connecting seat is connected to the connecting frame. Two spreading plates that rotate in opposite directions are rotatably connected to the connecting seat.

[0005] In one embodiment, the general compounding machine for automotive interior materials that prevents overflow further includes a lifting mechanism for driving the extrusion plate to slide. The lifting mechanism includes a first guide rod. A pair of first guide rods that slide up and down and a pair of sliding rods that slide up and down are provided at the top of the glue storage column. Elastic members are connected between the first guide rods and the glue storage column. The extrusion plate is connected between the two first guide rods. The bottom ends of the sliding rods are all connected to the extrusion plate. A connecting ring is connected to the sliding rods. Two electric push rods are connected to the glue storage column. The telescopic rods of the two electric push rods are both connected with a push rod with a hollow end. The push rods are all slidably connected to the sliding rods on the same side. When the push rods move down, they will push the connecting ring down.

[0006] In one embodiment, the general composite machine for anti-overflow automotive interior materials further includes a second guide rod. A pair of second guide rods are connected to the outer wall of the glue storage column. A baffle slides left and right on the two second guide rods. Two synchronizing rods are connected to the baffle. Guide grooves are formed in the upper parts of the synchronizing rods. The lower ends of the push rods are rotatably connected with first bumps.

[0007] In one embodiment, the guide grooves are divided into a vertical section on the lower side and an inclined section on the upper side. The two first bumps are respectively located in the two guide grooves.

[0008] In one embodiment, the general composite machine for anti-overflow automotive interior materials further includes an adjusting mechanism. The adjusting mechanism includes a gear. The spreading plate includes a rotating part. The spreading plate rotates around the rotating part. Gears are connected to the tops of the rotating parts. A connecting plate is connected to the middle of the connecting seat. A lead screw is rotatably connected to the connecting plate. A sliding column is arranged on the connecting plate in a sliding manner. The sliding column is threadedly connected with the lead screw. Rack bars are connected to the front and rear sides of the sliding column. The two rack bars are respectively engaged with the two gears.

[0009] In one embodiment, the adjusting mechanism further includes an L-shaped plate and a second bump. A pair of sliding L-shaped plates are arranged on the right side of the baffle. The L-shaped plates both have glue-blocking parts for blocking the glue outlet holes. Straight holes are formed in the right ends of the L-shaped plates. The ends of the two spreading plates far away from the rotating parts are rotatably connected with second bumps. The two second bumps are respectively located in the two straight holes.

[0010] In one embodiment, the general composite machine for anti-overflow automotive interior materials further includes a translation rod. Two sliding translation rods are arranged on the bracket. Two connecting rods I are connected to the bracket. A bidirectional screw is rotatably connected to each of the connecting rods I. The translation rod is threadedly connected with the bidirectional screw. Sliding blocks are arranged on the translation rods. A row of limit pins for inserting into the foam are connected to the two sliding blocks.

[0011] In one embodiment, the general composite machine for anti-overflow automotive interior materials further includes a connecting rod II. A connecting rod II is connected to the bracket. A rotating shaft is rotatably connected to the connecting rod II. Winding wheels are connected to both ends of the rotating shaft. Pulling ropes are wound around the winding wheels. The free ends of the two pulling ropes are respectively connected to the two sliding blocks.

[0012] The beneficial effects are as follows: 1. Glue is injected into the glue storage column through the glue inlet pipe. The electric push rod is controlled to move the push rod downward. The baffle opens. The downward-moving extrusion plate extrudes the glue in the glue storage column. The glue automatically and evenly extrudes from the glue outlet hole onto the surface of the foam. The spreading plate then spreads the glue evenly. The baffle prevents the glue from dripping onto the next position, improves the glue evenness, and effectively avoids the glue from overflowing from the edge of the foam, so as to perform composite processing on the foam and the interior layer.

[0013] 2. By rotating the lead screw, the sliding column and the rack are moved, so that the gear and the spreading plate rotate. The distance between the mutually remote ends of the two spreading plates is reduced to the width of the composite foam. With the cooperation of the second bump, the two L-shaped plates move synchronously. According to the width of the foam, the amount of glue injected each time is adjusted proportionally. When the baffle is opened, the glue-blocking part of the L-shaped plate blocks the glue outlet holes at the front and rear ends of the glue storage column, enabling the glue extrusion amount and the glue extrusion position to automatically adapt to the width of the foam, effectively improving the uniformity of the glue and with high synchronism.

[0014] 3. Align the tail end of the foam with the head end of the next roll of foam. The two translation rods approach each other, driving the slider and the limit pins close to the foam until the limit pins are inserted into the sides of the joint positions at the head and tail ends of the two rolls of foam. When the joint of the two rolls of foam is completed, the limit pins leave the foam, and the winding wheel winds the pulling rope to reset the slider and the limit pins, automatically positioning the ends of the two rolls of foam, avoiding deviation and dislocation, and improving the operation convenience and the overall production efficiency.

Detailed implementation manners

[0026] The present invention will be further described below in conjunction with the embodiments shown in the attached drawings.

[0027] Embodiment 1: A general composite machine for anti-spill automotive interior materials, referring to Figures 1 - 6 , including a bracket 1, a conveyor belt 2, side plates 3, a composite mechanism 4, a connecting frame 5, a glue storage column 6, an extrusion plate 7, a baffle 8, a connecting seat 9 and a spreading plate 10. A conveyor belt 2 is installed on the bracket 1, two symmetric side plates 3 are bolted in the middle of the bracket 1, and a composite mechanism 4 for laminating the foam 41 and the interior layer 42 is installed between the two side plates 3. The structure and principle of the composite mechanism 4 are prior arts. A connecting frame 5 is bolted between the two side plates 3. A hollow glue storage column 6 is fixedly connected to the lower part of the connecting frame 5. An extrusion plate 7 that slides up and down is arranged inside the glue storage column 6. A row of glue outlet holes 60 are evenly spaced on the bottom surface of the glue storage column 6. Two glue inlet pipes 61 are installed on the right side of the glue storage column 6, and one-way valves (not shown in the figure) are arranged in the glue inlet pipes 61. The one-way valves are prior arts. A baffle 8 that moves left and right and is used to block the glue outlet holes 60 is arranged below the glue storage column 6. A connecting seat 9 is welded on the connecting frame 5, and two spreading plates 10 that rotate in opposite directions are rotatably connected to the connecting seat 9.

[0028] Referring to Figures 3 - 6, the universal compounding machine for anti-overflow automotive interior materials further includes a lifting mechanism for driving the sliding of the extrusion plate 7. The lifting mechanism includes a first guide rod 71, a sliding rod 72, a connecting ring 73, an electric push rod 74, and a pushing rod 75. A pair of vertically sliding first guide rods 71 and a pair of vertically sliding sliding rods 72 are provided at the top of the glue storage column 6. Elastic members are fixedly connected between the first guide rods 71 and the top surface of the glue storage column 6. The elastic members are specifically springs. The extrusion plate 7 is fixedly connected between the bottom ends of the two first guide rods 71. The bottom ends of the sliding rods 72 are fixedly connected to the extrusion plate 7. A connecting ring 73 is fixedly connected to the middle of the sliding rod 72. Two electric push rods 74 are bolted to the top surface of the glue storage column 6. End hollow pushing rods 75 are connected to the telescopic rods of the two electric push rods 74. The lower ends of the pushing rods 75 are slidably connected to the sliding rods 72 on the same side. When the pushing rod 75 moves downward, it will push the connecting ring 73 downward.

[0029] Reference Figures 3 - 6 , the universal compounding machine for anti-overflow automotive interior materials further includes a second guide rod 81, a synchronous rod 82, and a first convex block 84. A pair of second guide rods 81 are fixedly connected to the left side of the outer wall of the glue storage column 6. The baffle 8 slides left and right on the two second guide rods 81. Two synchronous rods 82 are fixedly connected to the left side of the baffle 8. Guide grooves 83 are formed in the upper parts of the synchronous rods 82. First convex blocks 84 are rotatably connected to the outer walls of the lower ends of the pushing rods 75; the guide grooves 83 are divided into a vertical section on the lower side and an inclined section on the upper side. The two first convex blocks 84 are respectively located in the two guide grooves 83.

[0030] First, glue is injected into the glue storage column 6 through the glue inlet pipe 61. The one-way valve enables the glue to flow into the glue storage column 6 only in one direction. The baffle 8 blocks the glue outlet hole 60. When the injection of glue through the glue inlet pipe 61 is completed, the electric push rod 74 is controlled to drive the pushing rod 75 to move downward horizontally, driving the first convex block 84 to move downward. Since the first convex block 84 is located in the inclined section of the guide groove 83, the downward-moving first convex block 84 can make the synchronous rod 82 move leftward, driving the baffle 8 to slide leftward along the second guide rod 81 to open, and the baffle 8 no longer blocks the glue outlet hole 60; the pushing rod 75 and the first convex block 84 continue to move downward, and the first convex block 84 moves along the vertical section of the guide groove 83. When the pushing rod 75 contacts the connecting ring 73, the downward-moving pushing rod 75 pushes the connecting ring 73 downward, driving the sliding rod 72, the extrusion plate 7, and the first guide rod 71 to move downward, and the spring is compressed. The extrusion plate 7 extrudes the glue in the glue storage column 6 through the glue outlet hole 60, and the glue is extruded onto the surface of the lower foam 41.

[0031] Control the electric push rod 74 to move the push rod 75 and the first bump 84 upward to reset. Under the action of the spring, the first guide rod 71, the extrusion plate 7, the slide rod 72 and the connecting ring 73 move upward to reset. The upward-moving first bump 84 makes the synchronous rod 82 and the baffle 8 move rightward to reset through the inclined section of the guide groove 83. The baffle 8 blocks the glue outlet hole 60 again. At this time, glue can be continuously injected into the glue storage column 6 through the glue inlet pipe 61. In this way, the glue is automatically and evenly extruded from the glue outlet hole 60 onto the surface of the foam 41. The baffle 8 prevents the glue from dripping onto the next position, improves the uniformity of the glue, and effectively prevents the glue from overflowing from the edge of the foam 41.

[0032] When the part of the foam 41 coated with glue moves to the leveling plate 10, the glue on the surface of the foam 41 is evenly smeared through the leveling plate 10. Then, under the cooperation of the conveyor belt 2 and the composite mechanism 4, the foam 41 and the interior trim layer 42 can be subjected to composite processing.

[0033] Embodiment 2: On the basis of Embodiment 1, referring to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 , the general composite machine for anti-overflow automotive interior materials further includes an adjusting mechanism. The adjusting mechanism includes a gear 102, a connecting plate 103, a lead screw 104, a sliding column 105 and a rack 106. The leveling plate 10 includes a rotating part 101. The leveling plate 10 rotates around the rotating part 101. Gears 102 are fixedly connected to the tops of the rotating parts 101. A connecting plate 103 is fixedly connected to the middle of the connecting seat 9. A lead screw 104 is rotatably connected to the connecting plate 103. A sliding column 105 that slides left and right is provided on the connecting plate 103. The sliding column 105 is threadedly connected to the lead screw 104. Racks 106 are fixedly connected to the front and rear sides of the sliding column 105. The two racks 106 are respectively engaged with the two gears 102. The adjusting mechanism further includes an L-shaped plate 107 and a second bump 109. A pair of L-shaped plates 107 that slide back and forth are provided on the right side of the baffle 8. The left ends of the L-shaped plates 107 both have glue-blocking parts 1071 for blocking the glue outlet hole 60. Straight holes 108 are opened at the right ends of the L-shaped plates 107. Second bumps 109 are rotatably connected to the ends of the two leveling plates 10 away from the rotating part 101. The two second bumps 109 are respectively located in the two straight holes 108.

[0034] When it is necessary to compound the foam 41 with a smaller width, the screw rod 104 is rotated manually. Under the action of the threaded connection, the sliding column 105 slides leftward, driving the rack 106 to move leftward. The leftward moving rack 106 can make the front gear 102 rotate counterclockwise and the rear gear 102 rotate clockwise, driving the front leveling plate 10 to rotate counterclockwise with the rotating part 101 as the axis and driving the rear leveling plate 10 to rotate clockwise with the rotating part 101 as the axis. The distance between the mutually remote ends of the two leveling plates 10 is reduced to the width of the compounded foam 41. The leveling plate 10 drives the two second bumps 109 to approach each other in the front-rear direction. Since the second bumps 109 are located in the straight holes 108, the second bumps 109 will push the two L-shaped plates 107 to approach each other in the front-rear direction.

[0035] Then, the amount of glue injected by the glue storage column 6 per single injection is adjusted proportionally according to the width of the foam 41. The control of the glue injection amount is an existing technology. Then, the electric push rod 74 is controlled to lower the push rod 75. Similarly, the baffle 8 moves leftward to open, and the baffle 8 will also drive the L-shaped plate 107 to move leftward together. The glue blocking part 1071 of the L-shaped plate 107 blocks the glue outlet holes 60 at the front and rear ends of the glue storage column 6. When the downward moving extrusion plate 7 extrudes the glue, the glue can be extruded through fewer glue outlet holes 60, so that the glue extrusion amount and the glue extrusion position can automatically adapt to the width of the foam 41, effectively improving the uniformity of the glue and having high synchronism.

[0036] Embodiment 3: On the basis of Embodiment 2, referring to Figure 1 、 Figure 2 、 Figure 9 and Figure 10 ,the general composite machine for anti-overflow automotive interior materials further includes a translation rod 111, a first connecting rod 112, a bidirectional screw rod 113, a slider 114 and a limit pin 115. There are two translation rods 111 that slide back and forth on the bracket 1. The left and right parts of the bracket 1 are fixedly connected with first connecting rods 112 respectively. The first connecting rods 112 are rotatably connected with bidirectional screw rods 113 driven by a servo motor. The front translation rod 111 is threadedly connected to the front ends of the two bidirectional screw rods 113, and the rear translation rod 111 is threadedly connected to the rear ends of the two bidirectional screw rods 113. The translation rods 111 are respectively provided with sliders 114 that slide left and right. One side of the two sliders 114 that are close to each other is fixedly connected with a row of limit pins 115 for inserting the foam 41.

[0037] Referring to Figure 2 、 Figure 9 and Figure 10, the anti-overflow general composite machine for automotive interior materials further includes a second connecting rod 121, a rotating shaft 122, a winding wheel 123 and a pulling rope 124. The left part of the bracket 1 is fixedly connected with the second connecting rod 121. The second connecting rod 121 is rotatably connected with a rotating shaft 122 driven by a driving motor. Both the front and rear ends of the rotating shaft 122 are fixedly connected with winding wheels 123. Pulling ropes 124 are wound around the winding wheels 123. The free ends of the two pulling ropes 124 are respectively connected with two sliders 114.

[0038] When a roll of foam 41 is about to be used up, align the end of this roll of foam 41 with the head of the next roll of foam 41. Control the servo motor to drive the bidirectional screw 113 to rotate. Under the action of threaded connection, the two translation rods 111 approach each other in the front-rear direction, driving the sliders 114 and the limit pins 115 to approach the foam 41 until the limit pins 115 are inserted into the sides of the seam positions at the head and tail ends of the two rolls of foam 41, thereby positioning the foam 41. While the foam 41 continues to move to the right for lamination, control the driving motor to drive the rotating shaft 122 to rotate, driving the winding wheels 123 to rotate. The winding wheels 123 loosen the pulling ropes 124 so that the foam 41 can drive the sliders 114 and the limit pins 115 to move synchronously to the right until the lamination of the seam of the two rolls of foam 41 is completed. Then, control the servo motor to drive the bidirectional screw 113 to reverse, so that the translation rods 111, the sliders 114 and the limit pins 115 move and reset in the front-rear direction, and the limit pins 115 leave the foam 41. Then, control the driving motor to reverse the rotating shaft 122 and the winding wheels 123. The winding wheels 123 wind up the pulling ropes 124, and the pulling ropes 124 pull the sliders 114, so that the sliders 114 and the limit pins 115 move leftward and reset. In this way, the limit pins 115 can automatically position the ends of the two rolls of foam 41, avoiding deviation and misalignment, and improving the operation convenience and the overall production efficiency.
