Description

Technical Field

[0001] This utility model belongs to the field of automotive brake muffler processing technology, and in particular relates to an automotive brake muffler coating feeding device. Background Technology

[0002] Automotive brake dampers are rubber pads installed on automotive brake components to reduce braking noise during braking.

[0003] To enhance the wear resistance, aging resistance, high temperature resistance, and oxidation resistance of brake dampers, a coating is currently applied to the brake dampers to improve their functionality.

[0004] Specifically, during the production process, brake muffler blanks are transported via belt conveyors to equipment such as spraying and roller coating machines, where a coating is applied to the blanks. The blanks are then stamped using molds to form mufflers of a specific shape. Therefore, the uniformity of the coating is crucial to the performance of the muffler. Thus, during the coating process, it is necessary to maintain a smooth, unprotruding coating surface on the muffler blank to ensure uniform application of the coating material.

[0005] However, during the feeding process, since the rubber sound-absorbing sheet blank of a certain thickness is unwound and flattened from the roll before being fed onto the conveyor belt, the top surface of the rubber sound-absorbing sheet cannot be guaranteed to be flat. There are uneven structures such as bulges and wrinkles on the top surface. If the rubber sound-absorbing sheet blank is not flattened, the uneven structure will cause the coating material to not adhere evenly to the sound-absorbing sheet blank during the subsequent coating process, which will seriously affect the quality of the finished sound-absorbing sheet. For example, if the uniformity of the coating (such as thickness) is insufficient, the sound-absorbing sheet will be damaged before reaching its service life and cannot be used.

[0006] Therefore, after improving the flatness of the sound-absorbing sheet, applying a coating is the key to improving the quality of the sound-absorbing sheet. However, it is currently difficult to automatically level the sheet during the material transfer process in the production process. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a feeding device for coating automotive brake mufflers.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A feeding device for coating automotive brake damping pads includes a belt conveyor, which includes a frame and a conveyor belt mounted on the frame; damping pad blanks are transported via the conveyor belt.

[0010] The feeding device also includes a top frame installed at the top of the machine frame, on which are mounted several flattening roller mechanisms for flattening the sound-absorbing sheet blanks, and a smoothing mechanism for smoothing the sound-absorbing sheet blanks.

[0011] The flattening wheel mechanism includes a rotating rod rotatably connected to the top frame, with several pressure wheels symmetrically installed on both sides of the rotating rod;

[0012] Both ends of the rotating rod are equipped with a pulling structure to pull the rotating rod to rotate. After the rotating rod rotates, the pressure roller descends and presses against the sound-absorbing sheet blank to flatten the blank.

[0013] The smoothing mechanism includes several smoothing plates, which are pressed onto the sound-absorbing sheet blank for smoothing.

[0014] Preferably, belt drums are rotatably connected to the front and rear ends of the frame, and a conveyor belt is installed between the belt drums;

[0015] A motor that drives the belt drum to rotate is installed on one side of the belt drum.

[0016] Preferably, the flattening wheel mechanism is respectively located at the feed end and the discharge end of the conveyor belt;

[0017] The smoothing mechanism is located between the two flattening roller mechanisms;

[0018] The smoothing mechanism includes a first smoothing structure and a second smoothing structure.

[0019] Preferably, the top of the top frame is fixedly connected to the left and right sides of the top, and the rotating rod is rotatably connected between the protrusions;

[0020] The pressure roller includes a wheel frame, on which a rubber pressure roller is rotatably connected. The inner end of the wheel frame is fixedly connected to a wheel frame rod that is inclined downwards, and the wheel frame rod is fixedly connected to a rotating rod.

[0021] Preferably, the pulling structure includes a drive arm fixedly connected to the end of the rotating rod, the lower end of the drive arm is hinged to an electric push rod, and an ear seat is fixedly connected to the electric push rod. The ear seat is hinged to the outer wall of the top frame by a pin.

[0022] Preferably, the first smoothing structure includes a first smoothing plate, with protrusions fixedly connected to both sides of the top of the first smoothing plate, and a long screw fixedly connected between the protrusions;

[0023] The top frame has fixed seats on both sides of its top, and the two ends of the long screw are threaded onto the fixed seats; the two ends of the long screw are threaded onto positioning nuts.

[0024] After adjusting the distance between the first trowel plate and the conveyor belt by rotating the first trowel plate, the first trowel plate is positioned by pressing the fixing seat with the positioning nut.

[0025] Preferably, the second smoothing structure includes a second smoothing plate, with protruding seats fixedly connected to the top two sides of the second smoothing plate, and a long rotating rod fixedly connected between the protruding seats. Fixed rotating seats that rotatably connect the long rotating rod are fixedly connected to the top two sides of the top frame.

[0029] This utility model has the following beneficial effects:

[0030] 1. During operation, the electric push rod's extension and retraction cause the drive arm to rotate clockwise and counterclockwise. During these rotations, the rubber pressure rollers and wheel brackets on both sides alternately lift and press down. For example, after the front rubber pressure roller and wheel bracket press down, the rear rubber pressure roller and wheel bracket lift up. The front rubber pressure roller and wheel bracket flatten the billet with a single press. As the billet continues to move, the electric push rod's extension and retraction cause the rear rubber pressure roller and wheel bracket to press down while the front ones lift up. This process achieves flattening of the billet by the alternating pressure of the rubber pressure rollers on both sides. This method flattens uneven structures on the billet using the pressure of the rubber pressure rollers.

[0031] 2. The work process is achieved by using the first and second troweling plates to flatten the entire blank through the troweling method of the first and second troweling plates.

[0032] 3. The device disclosed in this utility model enables the sound-absorbing sheet blank to be fully leveled before coating. After leveling, it can ensure that the thickness and uniformity of the coating after spraying are high, which greatly improves the service life of the finished sound-absorbing sheet.

[0043] Example 1

[0044] like Figure 1-5 As shown, a coating feeding device for automotive brake damping pads includes a belt conveyor 2. The belt conveyor 2 is a conventional belt conveyor disclosed in the prior art. The main structure includes a frame and a conveyor belt mounted on the frame. Specifically, it is the same as the existing belt conveyor structure, with belt drums rotatably connected to the front and rear ends of the frame, and a conveyor belt installed between the belt drums; a motor for driving the belt drum to rotate is installed on one side of the belt drum.

[0045] During operation, the motor drives the lower belt drum to rotate, and the blank placed on the conveyor belt is transferred to processing equipment such as spraying equipment for spraying.

[0046] Specifically, in order to achieve the goal of leveling the sound-absorbing sheet blank before it enters the spraying equipment, and to maintain a very high degree of flatness on the coating surface of the blank before coating.

[0047] The above-mentioned feeding device also includes a top frame 1 (fastened by bolts) installed at the top of the machine frame, a number of flattening roller mechanisms 3 for flattening the sound-absorbing sheet blanks, and a smoothing mechanism for smoothing the sound-absorbing sheet blanks.

[0048] Specifically, the flattening wheel mechanism 3 is respectively set at the feed end and discharge end of the conveyor belt (i.e., at the front and rear ends of the frame).

[0049] The smoothing mechanism is located between the two flattening roller mechanisms 3. Therefore, after the sound-absorbing sheet blank is flattened by the flattening roller mechanism 3 and smoothed by the smoothing mechanism, the flatness of its coating surface is significantly improved, which prepares it for subsequent coating.

[0050] The aforementioned flattening wheel mechanism 3 includes a rotating rod 31 rotatably connected to the top frame 1, with several pressure wheels symmetrically installed on the front and rear sides of the rotating rod 31. Specifically, protrusions are fixedly connected to the left and right sides of the top of the top frame 1, and the rotating rod 31 is rotatably connected between the protrusions; the pressure wheel includes a wheel frame, on which a rubber pressure wheel 33 is rotatably connected, and an inclined downward-facing wheel frame rod 32 is fixedly connected to the inner end of the wheel frame, and the wheel frame rod 32 is fixedly connected to the rotating rod 31.

[0051] Similarly, the wheel frame rod 32 is symmetrically arranged front and back. At the same time, the left and right ends of the rotating rod 31 are respectively equipped with a pulling structure to pull the rotating rod 31 to rotate. After the rotating rod 31 rotates, the pressure roller descends and presses against the sound-absorbing sheet blank to flatten the blank.

[0052] Specifically, the pulling structure includes a drive arm 34 fixedly connected to the end of the rotating rod 31. The lower end of the drive arm 34 is hinged to an electric push rod 35 (a conventional electric telescopic rod disclosed in the prior art). An ear seat is fixedly connected to the electric push rod 35, and the ear seat is hinged to the outer wall of the top frame 1 by a pin.

[0053] During operation, under the pushing and extending motion of the electric push rod 35, the drive arm 34 carries the rotating rod 31 to rotate clockwise and counterclockwise. During the clockwise and counterclockwise rotation of the rotating rod 31, the rubber pressure rollers 33 and wheel frame rods 32 on both sides alternately lift and press down. For example, after the front rubber pressure rollers 33 and wheel frame rods 32 press down, the rear rubber pressure rollers 33 and wheel frame rods 32 lift up. At this time, after the front rubber pressure rollers 33 and wheel frame rods 32 press down, they flatten the billet with one touch. As the billet continues to move, under the pushing and extending motion of the electric push rod 35, the rear rubber pressure rollers 33 and wheel frame rods 32 press down, and the front ones lift up. In this process, the billet is flattened by the alternating touch of the rubber pressure rollers 33 on both sides.

[0054] Example 2

[0055] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 1. The smoothing mechanism includes several smoothing plates, which are pressed onto the sound-absorbing sheet blank for smoothing. Specifically, the smoothing mechanism includes a first smoothing structure 4 and a second smoothing structure 5.

[0056] The first smoothing structure 4 includes a first smoothing plate 42. A protrusion is fixedly connected to both sides of the top of the first smoothing plate 42, and a long screw 41 is fixedly connected between the protrusions. Correspondingly, a fixed seat is fixedly connected to both sides of the top of the top frame 1, and both ends of the long screw 41 are threaded onto the fixed seat. A positioning nut 411 is threaded onto both ends of the long screw 41. After rotating the first smoothing plate 42 to adjust the distance between the first smoothing plate 42 and the conveyor belt, the positioning nut 411 presses against the fixed seat to position the first smoothing plate 42.

[0057] During the operation, after the blank passes through the first troweling plate 42, which is pre-adjusted to be spaced from the conveyor belt, the uneven structure on the blank is smoothed and leveled by the troweling pressure of the first troweling plate 42.

[0058] This method allows for further leveling of the billet.

[0059] Example 3

[0060] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, the second smoothing structure 5 includes a second smoothing plate 51. Protruding seats are fixedly connected to both sides of the top of the second smoothing plate 51, and a long rotating rod 52 is fixedly connected between the protruding seats. Fixed rotating seats that rotatably connect the long rotating rod 52 are fixedly connected to both sides of the top of the top frame 1. A spring-loaded clamping structure 6 is fixedly connected to the second smoothing plate 51. Specifically, the spring-loaded clamping structure 6 includes several clamping springs 61 fixedly connected to the front sidewall of the second smoothing plate 51. Spring brackets 62 are fixedly connected between the ends of the clamping springs 61, and the two ends of the spring brackets 62 are fixedly connected to the sidewall of the top frame 1.

[0061] During the operation, as the billet passes through the second troweling plate 51, it is affected by the billet (specifically, uneven parts of the billet, such as raised parts). The second troweling plate 51 flips (because the clamping spring 61 has a certain degree of freedom of deformation, the clamping spring 61 bends and deforms when the billet comes into contact with the second troweling plate 51). During the flipping process, the second troweling plate 51 immediately returns to its original position after flipping due to the action of the clamping spring. Therefore, the billet is leveled by the continuous slight flipping and resetting action of the second troweling plate 51.

[0062] In actual operation, the distance between the second trowel plate 51 (in a free state) and the conveyor belt is designed to be smaller than the distance between the first trowel plate 42 and the conveyor belt, so that the second trowel plate 51, which has a certain degree of freedom, can perform preliminary troweling and leveling, and the first trowel plate 42 can perform full troweling and leveling.

[0063] The bottom of the first troweling plate 42 and the second troweling plate 51 are integrally formed with a smoothing part A. The smoothing part A has a sloping structure to increase the contact area with the blank.

[0064] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
