Description

Technical Field

[0001] This invention relates to the field of rubber skeleton coating, and more particularly to a fully automated rubber skeleton coating production line. Background Technology

[0002] Rubber skeleton materials are the main load-bearing components in composite rubber products containing skeleton materials. They also play an important role in the shape stability of these rubber products during use. For example, tires, belts, some rubber hoses, bushings, seals and shock-absorbing rubber products are composed of rubber elastomer components and high-modulus, high-strength skeleton materials. The firm bond between the rubber and its skeleton not only protects the skeleton material, but also allows the reinforcing effect of the skeleton material to be fully utilized.

[0003] Bushings are a type of component that protects equipment. The use of bushings can reduce wear, vibration and noise of equipment, and has the effect of corrosion protection. The use of bushings can also facilitate the maintenance of mechanical equipment, simplify the structure and manufacturing process of equipment. Bushings are used in many parts of automobiles. The application of rubber skeleton material is the application of the bushing skeleton.

[0004] Existing bushing gluing production lines control the feeding, gluing, drying, and unloading of bushing skeletons by coordinating different equipment through a control system. This results in high operating costs, and the production line stops operating when the bushing skeleton is being fed, waiting for the feeding mechanism to complete the fitting of the bushing skeleton before restarting, which affects production efficiency. This invention solves the above problems. Summary of the Invention

[0005] To address the technical problem of existing bushing adhesive coating production lines that rely on a control system to coordinate different devices to control the feeding, adhesive coating, drying, and unloading of bushing skeletons, resulting in high operating costs and the production line stopping during bushing skeleton feeding, this invention provides a fully automatic rubber skeleton adhesive coating production line.

[0006] A fully automatic rubber skeleton coating production line includes: a frame, a fixed plate connected to the upper surface of the frame, a closed annular ball groove formed on the outer surface of the fixed plate, the annular ball groove including a straight section and a crest section, a ball head end of a ball head slide rod slidably connected inside the annular ball groove, the ball head slide rod remaining horizontal when the ball head end is in the straight section, the rod part of the ball head slide rod being slidably connected to a rotating block, the rotating block being rotatably connected to a rotating frame, multiple sets of rotating frames arranged in a circumferential array outside the fixed plate, each set of rotating frames having a turntable connected to its upper surface, the turntable being connected to the upper end of a power output shaft, the power output shaft being rotatably connected to the fixed plate, and the lower end of the power output shaft being connected to a motor. The machine is connected to the motor located inside the frame. The straight section is equipped with a feeding mechanism, a gluing mechanism, and a drying mechanism in sequence along the rotation direction of the turntable. The annular ball groove also includes a concave section located inside the straight section and within the notch of the fixed plate. The feeding mechanism is located outside the concave section and includes a hopper. The lower end of the hopper is connected to a square cylinder, which is connected to the outer wall of the frame. The square cylinder can only accommodate one row of horizontally stacked bushing frames. The lower end of the long side wall of the square cylinder has a notch, through which the bushing frames can be discharged. The ball head slide rod of the concave section can be inserted into the bottom bushing frame. A counterweight door is rotatably connected to the outer wall of the square cylinder at the notch.

[0007] Furthermore, the outer wall of the square tube is connected to a limiting arc plate, and the distance between the limiting arc plate and the ball head slide rod gradually decreases along the rotation direction of the turntable until they fit together.

[0008] Furthermore, the square tube has only one wide sidewall.

[0009] Furthermore, the adhesive application mechanism includes a belt drive, the lower surface of the limiting arc plate is in contact with the upper surface of the belt drive, the bushing skeleton on the ball head slide rod is tangent to the upper surface of the belt drive, the end of the belt drive roller shaft is rotatably connected to the glue container, the bottom wall of the glue container is provided with a heating element, and the glue container is fixed by a container support.

[0010] Furthermore, sealing plates are provided on both sides of the belt drive, and the belt drive roller end is rotatably connected inside the sealing plate, with the sealing plate in contact with both sides of the belt drive belt.

[0011] Furthermore, the air-drying mechanism includes an air-drying bracket, which is located at the bottom of the ball-head slide bar and connected to the outer wall of the frame. A fan is connected to the air-drying bracket, and the fan can blow air vertically upward.

[0012] Furthermore, the lower part of the crest section of the annular ball groove is provided with a receiving cloth spirally wound around the outer wall of the frame. The receiving cloth can receive the fallen bushing skeleton, and the receiving cloth is fixed by the cloth frame.

[0013] Beneficial effects of this invention:

[0014] 1. By controlling the ball head slide rod to run within the concave section of the annular ball groove, the automatic extension and retraction of the ball head is controlled, allowing it to be inserted into the stationary bushing skeleton for feeding, thus achieving feeding without stopping the machine;

[0015] 2. By controlling the ball head slide rod to run in the straight section of the annular ball groove, the bushing skeleton is driven to make full contact with the belt drive. Compared with the traditional rubber roller, the belt drive has the advantages of larger adhesive volume and longer contact time with the bushing skeleton, ensuring the quality of adhesive application. After the adhesive application is completed, the fan blows it dry and sets the shape.

[0016] 3. By controlling the ball head slide rod to run within the crest section of the annular ball groove, the ball head slide rod is driven to tilt downwards, causing the drying bushing to fall off, thus completing the automatic feeding. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] Example 1:

[0027] The following is in conjunction with the appendix Figure 1-5 This embodiment describes a fully automatic rubber skeleton coating production line, comprising: a frame 1, a fixed plate 2 connected to the upper surface of the frame 1, a closed annular ball groove 3 on the outer surface of the fixed plate 2, the annular ball groove 3 including a straight section A and a crest section B, a ball head slide rod 4 slidably connected inside the annular ball groove 3, the ball head slide rod 4 maintaining a horizontal state when the ball head slide rod 4 is located in the straight section A, the rod part of the ball head slide rod 4 slidably connected inside a rotating block 5, the rotating block 5 rotatably connected inside a rotating frame 6, multiple sets of rotating frames 6 arranged in a circular array outside the fixed plate 2, each set of rotating frames 6 having a turntable 7 connected to its upper surface, the turntable 7 connected to the upper end of a power output shaft 8, the power output shaft 8 rotatably connected inside the fixed plate 2, the lower end of the power output shaft 8 connected to a motor 9 located inside the frame 1, and a feeding mechanism 10, a coating mechanism 11, and a drying mechanism 12 sequentially arranged along the rotation direction of the turntable 7 outside the straight section A.

[0028] The annular ball groove 3 also includes a concave section C, which is located inside the straight section A. The concave section C is located inside the notch of the fixed plate 2. The feeding mechanism 10 is located outside the concave section C. The feeding mechanism 10 includes a hopper 101. The lower end of the hopper 101 is connected to the square tube 102. The square tube 102 is connected to the outer wall of the frame 1. The square tube 102 can only accommodate one row of horizontally stacked bushing frames. The lower end of the long side wall of the square tube 102 is provided with a notch 103. The bushing frames can be discharged along the notch 103. The ball head slide rod 4 of the concave section C can be inserted into the bottom bushing frame. The outer wall of the square tube 102 at the notch 103 is rotatably connected to a counterweight door 104.

[0029] In use, the motor 9 is turned on, which drives the power output shaft 8 to rotate. The power output shaft 8 drives the turntable 7 to rotate, and the turntable 7 drives multiple sets of rotating frames 6 to rotate synchronously. The multiple sets of rotating frames 6 drive the ball end of the ball head slide rod 4 to slide in the annular ball groove 3 through the rotating block 5, adding a bushing skeleton into the hopper 101. The bushing skeleton is arranged in a row and stacked horizontally in the square cylinder 102. When the ball end of the ball head slide rod 4 moves to the concave section C of the annular ball groove 3, the ball head slide rod 4 moves towards the fixed plate 2. The ball head slide rod 4 slides and contracts within the notch. When it rotates to the bottommost bushing skeleton, it extends along the inclined surface of the concave section C and inserts into the bottommost bushing skeleton, driving the bottommost bushing skeleton to slide through the notch 103 to complete the feeding. The ball head slide rod 4 drives the bushing skeleton to continue running in the straight section A. After being glued by the glue coating mechanism 11 and dried by the air drying mechanism 12, the processing is completed. Then, the ball head slide rod 4 drives the movement to the crest section B. The ball head slide rod 4 rises, causing the finished part to slide down and complete the discharge.

[0030] The outer wall of the square tube 102 is connected to a limiting arc plate 105. The distance between the limiting arc plate 105 and the ball head slide rod 4 gradually decreases along the rotation direction of the turntable 7 until they fit together.

[0031] The limiting arc plate 105 can effectively prevent the bushing skeleton from being thrown out by the ball head slide rod 4 under centrifugal force.

[0032] Square tube 102 has only one side wall facing outwards;

[0033] It facilitates handling when the bushing skeleton tilts or gets stuck.

[0034] The glue application mechanism 11 includes a belt drive 111, the lower surface of the limiting arc plate 105 is in contact with the upper surface of the belt drive 111, the bushing skeleton on the ball head slide rod 4 is tangent to the upper surface of the belt drive 111, the roller end of the belt drive 111 is rotatably connected to the glue container 112, the bottom wall of the glue container 112 is provided with a heating element, and the glue container 112 is fixed by the container support 113.

[0035] The rubber container 112 keeps the rubber in a liquid state through a heating element, and turns on the belt drive 111. The lower belt of the belt drive 111 contacts the liquid rubber at the bottom and transports it to the upper part. The belt rotates and contacts the bushing skeleton to apply the adhesive. Compared with traditional rubber rollers, the belt drive 111 has the advantages of larger adhesive volume and longer contact time with the bushing skeleton, ensuring the quality of adhesive application.

[0036] Both sides of the belt drive 111 are provided with sealing plates 114. The roller end of the belt drive 111 is rotatably connected to the sealing plate 114. The sealing plate 114 is in contact with both sides of the belt of the belt drive 111.

[0037] The sealing sheet 114 can prevent liquid rubber from entering the belt drive 111 and causing adhesion.

[0038] The air drying mechanism 12 includes an air drying bracket 121, which is located at the bottom of the ball head slide rod 4. The air drying bracket 121 is connected to the outer wall of the frame 1, and a fan 122 is connected to the air drying bracket 121. The fan 122 can blow air vertically upward.

[0039] The blower 122 blows air from bottom to top onto the rubber-coated bushing skeleton, causing the bushing skeleton to rotate on the ball head slide rod 4, and the bushing rubber to dry evenly.

[0040] The lower part of the crest section B of the annular ball groove 3 is provided with a receiving cloth 13 spirally wound around the outer wall of the frame 1. The receiving cloth 13 can receive the fallen bushing skeleton. The receiving cloth 13 is fixed by the cloth frame 14.

[0041] The air-dried bushing falls onto the receiving cloth 13. Due to the soft contact, the rubber layer of the bushing will not be damaged. It is then guided out by the spiral receiving cloth 13.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
