Description

Technical Field

[0001] This utility model is an automatic material guiding and turning robot under the rollers of an open mill, belonging to the field of rubber machinery technology. Background Technology

[0002] The open mill is one of the most commonly used pieces of equipment in the rubber processing industry. It is usually used in combination with the internal mixer. It is used to melt and blend a wide variety of materials, including natural rubber, synthetic rubber, PVC, PE, PP, and EVA, which are produced by vulcanization and injection molding. All these materials require dispersion and mixing in both the internal mixer and the open mill. After mixing raw materials according to specific technical requirements in the internal mixer, the original colloids, granules, and powders are fused and dissolved into granules. However, the degree of dispersion between the materials within the granules is still very low, insufficient to meet the standards for the next process. Therefore, the materials must undergo further processing in the open mill, such as thin-passing, triangular packing, sheeting, or granulation, to ensure thorough mixing and dispersion of the materials within the granules.

[0003] The open mill mainly uses rollers to crush rubber lumps into thin sheets, and then uses a feeding device to guide the sheets, causing the sheets to fold and bend, so that the rubber lumps in different areas are mixed. After repeating this operation, a fully dispersed rubber compound can be obtained.

[0004] The existing open mill material feeding and turning devices mostly have pushers on both sides that can only perform linear reciprocating motion in one direction. They can only squeeze the total rubber flakes in the downward process in the left and right directions. The rubber flakes can only achieve lateral folding to form unidirectional wrinkles under the left and right compression, resulting in a mediocre mixing effect. It is necessary to increase the number of cycles to obtain a fully dispersed rubber compound. Utility Model Content

At the same time, the second driven gear rotates counterclockwise, causing the telescopic rack on the right to move backward, thereby retracting the robot arm on the right.

[0017] When the main gear rotates counterclockwise, the first driven gear rotates clockwise, driving the left telescopic rack to move backward, so that the left mechanical hand is retracted, at the same time, the second driven gear rotates clockwise, driving the right telescopic rack to move forward, so that the right mechanical hand is extended.

[0022] Further, the front-rear moving motor is matched with the telescopic rack through a gear set, so as to convert the rotary motion of the front-rear moving motor into the linear motion of the telescopic rack, thereby driving the telescopic movement of the mechanical hand.

[0045] The power device 3 includes front-back moving motor 31 and transverse moving motor 32 arranged side by side on the moving seat 21, to ensure that the mechanical hand 24 can respond stably and quickly during work.

[0046] In order to realize the turnover of the material, when the moving seat 21 moves from left to right, the left mechanical arm 24 extends while the right mechanical arm 24 retracts, and when the moving seat 21 moves from right to left, the right mechanical arm 24 extends while the left mechanical arm 24 retracts, through the opposite actions of the left and right mechanical arms 24, the material is alternately pushed and pulled, forming turnover and folding, thereby realizing efficient turnover operation.

[0047] In order to realize the opposite actions of the mechanical arms, the gear set 25 contains a main gear 251 located at the center of the front side inside the moving seat 21, a first driven gear 252 engaged with the telescopic rack 23 on the left second linear guide rail 22, and a second driven gear 253 engaged with the telescopic rack 23 on the right second linear guide rail 22.

[0048] In order to realize the extension action of the left mechanical arm, when the main gear 251 rotates clockwise, the first driven gear 252 rotates counterclockwise, driving the left telescopic rack 23 to move forward, thereby making the left mechanical arm 24 extend, at the same time, the second driven gear 253 rotates counterclockwise, driving the right telescopic rack 23 to move backward, thereby making the right mechanical arm 24 retract;

[0051] In order to ensure the stability of the moving seat, the moving seat 21 is slidably arranged on the first linear guide rail 12 by at least four guide blocks 121, to ensure the stability and linear motion accuracy of the moving seat 21.

[0052] In order to ensure the stability of the mechanical arm, at least six second guide blocks 221 are arranged inside the moving seat 21, to ensure the stability and linear motion accuracy of the mechanical arm 24.

[0053] In order to realize the left and right movement function of the moving seat, the bottom of the moving seat 21 is provided with a moving gear 131 between the moving rack 13 and the first linear guide rail 12 located at the rear side of the moving device 1, the moving gear 131 is engaged with the moving rack 13 and is driven by the transverse moving motor 32, to realize the left and right movement of the moving seat 21.

[0054] In order to achieve the conversion of the motion mode, the forward and backward moving motor 31 cooperates with the telescopic rack 23 through the gear set 25 to convert the rotational motion of the forward and backward moving motor 31 into the linear motion of the telescopic rack 23, thereby driving the extension and retraction of the robot arm 24.

[0055] Example 1:

[0056] like Figure 6 As shown, when the movable seat 21 moves to the left, the transverse moving motor 32 drives the moving gear 131, which meshes with the moving rack 13, causing the movable seat 21 to move to the left along the first linear guide rail 12. When the movable seat 21 is at its leftmost position, the front and rear moving motor 31 drives the main gear 251 to rotate clockwise. The main gear 251, through meshing with the first driven gear 252 and the second driven gear 253, drives the left telescopic rack 23 to move forward, causing the left robotic arm 24 to extend. At the same time, the right telescopic rack 23 moves backward, causing the right robotic arm 24 to retract. Specifically, during the process of the movable seat 21 moving to the left, the right robotic arm 24 pushes and pulls the material to the left, forming a fold on the left side. When the movable seat 21 is at its leftmost position, the right robotic arm 24 is completely retracted, while the left robotic arm 24 is completely extended.

[0057] Example 2:

[0058] like Figure 7 As shown, when the moving seat 21 moves to the right, the transverse moving motor 32 drives the moving gear 131 in the opposite direction, and the moving seat 21 moves to the right along the first linear guide rail 12. At this time, the front and rear moving motor 31 drives the main gear 251 to rotate counterclockwise. The main gear 251, through meshing with the first driven gear 252 and the second driven gear 253, drives the left telescopic rack 23 to move backward, and the left robot arm 24 retracts. At the same time, the right telescopic rack 23 moves forward, and the right robot arm 24 extends. Specifically, during the process of the moving seat 21 moving to the right, the left robot arm 24 pushes and pulls the material to the right, forming a fold on the right side. When the moving seat 21 is at the rightmost position, the left robot arm 24 is completely retracted, and at the same time, the left robot arm 24 is completely extended.

[0059] In this application, the alternating motion of the robotic arm 24 pushes the material from one side to the other, achieving material guidance and uniform distribution. In addition, when the moving device 1 moves left and right, the robotic arm 24 on the telescopic device 2 extends on one side and retracts on the other side, forming the flipping and folding of the material. Through continuous pushing and pulling motions, the material is continuously folded and covered, forming a multi-folded structure.

[0060] This application enables the robot arm 24 to extend or retract accordingly while the moving base 21 moves left and right, through the cooperation of the power unit 3, the gear set 25 and the telescopic rack 23, so as to adapt to different work requirements.

[0061] like Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the present invention used on an open mill. The open mill A1 has two rollers arranged side by side on the left and right sides. The two rollers are installed on the upper end of the left and right side frames of the open mill A1. The left side of the open mill A1 is provided with a lifting mechanism A2 for assisting in the lifting operation of materials. In the middle of the right side frame of the open mill A1, an automatic material guiding and turning robot of this application is slidably installed. Its design allows the robot 24 to be accurately positioned between the two rollers when it is extended, so as to achieve efficient material guiding and turning operations. The number of the automatic material guiding and turning robot is preferably one, but it can be flexibly adjusted to multiple according to actual needs.

[0062] like Figure 8 As shown, during the working process, the material is stretched into a sheet-like structure by the squeezing action of the rollers and continuously conveyed downwards. At this time, the robot arm 24 pushes and pulls the material that has been stretched to the left and right together by continuous left and right pushing and pulling actions, forming a multi-folded structure with left and right overlap and front and back coverage, thereby realizing the efficient mixing and processing of the material. This design not only improves the processing efficiency of the material, but also ensures the uniform mixing and processing of the material in the open mill A1.

[0063] This application also includes an external controller that can control the left and right movement of the movable base 21 and the forward and backward extension of the robotic arm 24 through an intelligent control program according to the set program and frequency. The operator can control the moving speed of the movable base 21 and the extension speed of the robotic arm 24 by adjusting the relevant parameters.

[0064] This application adopts a dual transmission structure. Through the cooperation of the moving device 1 and the telescopic device 2, the robot arm 24 has high stability and linear motion accuracy during operation. The moving seat 21 is slidably mounted on the first linear guide rail 12 via the guide rail block 121, and is provided with multiple second guide rail blocks 221 inside, which further enhances the stability and motion accuracy of the robot arm 24 during extension and retraction.

[0065] The telescopic device 2 of this application, through the cooperation of the gear set 25 and the telescopic rack 23, can realize the opposite movements of the left and right robotic arms 24 when the moving seat 21 moves, making the robotic arms 24 more flexible and efficient in material guiding and flipping operations, and enabling the material to be fully flipped and folded.

[0066] The application reduces the risk of mechanical failure and operation error, improves the safety of the equipment, and cooperates with the front and rear moving motor 31 and the transverse moving motor 32 in the power device 3, so that the mechanical hand 24 can stably and quickly respond in the working process, realizes automatic operation, improves the production efficiency and product quality.
