A skeleton testing device for rubber products with skeleton

Abstract

This invention discloses a skeleton detection device for rubber products with a skeleton, relating to the field of rubber product testing technology. It includes a lifting mechanism and a horizontal conveyor belt. The rubber product enters the horizontal conveyor belt via the lifting mechanism. The horizontal conveyor belt is sequentially equipped with a height limiting mechanism, a width limiting mechanism, and a belt weighing system along the conveying direction. The width limiting mechanism also includes a distance-controlled, equidistant arrangement structure for the rubber products. The height limiting mechanism mounts a height-limiting pusher wheel on a lifting module, and the pusher wheel continuously rotates, restricting multi-layered rubber products to a single layer and preventing the rubber products from getting stuck on the horizontal conveyor belt due to direct height stops. The width limiting structure restricts the material to pass through in a single column. The rotating width-limiting turntable controls the transfer speed of the rubber products, and excess rubber products flow back into the feed box, preventing accumulation on the surface of the horizontal conveyor belt.

Description

Technical Field

[0001] This invention relates to the field of rubber product testing technology, specifically to a skeleton testing device for rubber products with skeletons. Background Technology

[0002] Reinforcing rubber products are important materials widely used in automotive, machinery, engineering, and construction industries, and their quality directly affects their performance and safety. The reinforcing skeleton is the core component of a reinforcing rubber product, and its quality directly impacts the overall quality of the product. Therefore, testing the reinforcing skeleton of reinforcing rubber products is of great significance.

[0003] Due to the large output of rubber products during production, manual inspection would be too labor-intensive and prone to missed or incorrect inspections. Since the skeleton of a rubber product with a skeleton is generally not much different in appearance from that of an ordinary rubber product, using an industrial camera would be too costly and have low recognition speed. Furthermore, since a rubber product with a skeleton has an internal metal or rubber skeleton, there will be differences in the quality of each individual product. Based on this, we provide a skeleton inspection device for rubber products with a skeleton. Summary of the Invention

[0004] The purpose of this invention is to provide a skeleton testing device for rubber products with skeletons.

[0005] The technical problem solved by this invention is:

[0006] (1) How to sort rubber products by using height limiting mechanism and width limiting mechanism to solve the problem of disorderly arrangement of rubber products when they arrive at the weighing system, resulting in multiple layers and rows;

[0007] (2) How to control the rubber products at equal intervals by setting an equidistant arrangement structure so that they enter the weighing system in an orderly manner, thereby ensuring stable and continuous weighing of two belt weighing systems of different lengths, solving the problem of unstable weighing of belt weighing systems and the inability to verify errors, and also enabling the smooth separation of rubber products.

[0008] The present invention can be achieved through the following technical solution: a skeleton detection device for a rubber product with skeleton, comprising a lifting mechanism and a horizontal conveyor belt. The rubber product enters the horizontal conveyor belt through the lifting mechanism. The horizontal conveyor belt is sequentially provided with a height limiting mechanism, a width limiting mechanism and a belt weighing system along the conveying direction. The width limiting mechanism is also provided with an equidistant arrangement structure for distance control of the rubber product.

[0009] A further technical improvement of the present invention is that: the height limiting mechanism includes a vertical mounting plate, a lifting module is mounted on one side of the vertical mounting plate, and a height limiting pusher wheel driven by a motor is fixed at the output end of the lifting module.

[0010] A further technical improvement of the present invention is that the height-limiting pusher is an impeller-shaped structure with multiple grid plates evenly arranged in the radial direction of the circumference, and the tangential direction of the movement of the grid plates near the horizontal conveyor belt is opposite to the conveying direction of the horizontal conveyor belt.

[0011] A further technical improvement of the present invention is that the width limiting mechanism includes a transverse module disposed directly above the horizontal conveyor belt, and the output end of the transverse module is provided with a width limiting turntable driven by a speed regulating motor. The width limiting turntable and one side edge of the horizontal conveyor belt form a channel for a single row of rubber products to pass through.

[0012] A further technical improvement of the present invention is that the tangential velocity direction of the width-limiting turntable at the outermost end of the side edge forming the channel with the horizontal conveyor belt is consistent with the conveying direction of the horizontal conveyor belt.

[0013] A further technical improvement of the present invention is that: the equidistant arrangement structure includes an opening and closing channel formed by two guide plates, and a baffle controlled by an intermittent groove wheel structure is provided at the outlet of the opening and closing channel.

[0014] A further technical improvement of the present invention is that: the intermittent grooved wheel structure includes a continuously rotating disk, a telescopic rod with an adjustable extension length is provided on the disk, a rolling wheel is rotatably installed at the end of the telescopic rod, an intermittent turntable is provided on one side of the rotating disk, and multiple intermittent mating grooves that cooperate with the rolling wheel are evenly opened at equal angles on the outer side of the intermittent turntable, and multiple actuating pins are also adjustablely fixedly connected to the intermittent turntable by bolts.

[0015] A further technical improvement of the present invention is that the stop bar is rotatably set by a torque spring, and multiple actuating pins intermittently contact and engage with the stop bar.

[0016] A further technical improvement of the present invention is that the belt weighing system includes two belt weighing mechanisms of different lengths. The longer belt weighing mechanism weighs multiple rubber products. Data is compared from two dimensions: single weighing and multiple joint weighing and averaging. When the weighing deviation exceeds the set value, the marked abnormal rubber products are screened and removed by the separation mechanism.

[0017] A further technical improvement of the present invention is that the separation mechanism includes a pusher plate and a pusher cylinder that drives the pusher plate to move.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By installing the height-limiting pusher wheel on the lifting module through the height-limiting mechanism, and keeping the height-limiting pusher wheel rotating continuously, the multi-layered rubber products are restricted to a single layer. This also prevents the rubber products from getting stuck on the horizontal conveyor belt due to the direct use of height stops, thus avoiding wear and tear on the rubber products and the horizontal conveyor belt.

[0020] 2. The material is restricted to pass through in a single row by the width limiting structure. The rotating width limiting turntable can control the transfer speed of the rubber products. Excess rubber products will be squeezed out of the horizontal conveyor belt and flow back to the feed box for re-feeding and conveying, and will not accumulate on the surface of the horizontal conveyor belt.

[0021] 3. The equidistant arrangement of the width-limiting structure controls the movement of the baffles through the intermittent grooved wheel structure, thereby controlling the opening and closing state of the box opening channel. Under the action of the horizontal conveyor belt, the distance between the two rubber products is increased so that they enter the subsequent belt weighing system. The two belt weighing mechanisms of different lengths weigh stably and continuously, so that the number of rubber products on the two belt weighing mechanisms remains consistent in each weighing process. This allows for quick identification of the quality error of the rubber products and also facilitates the smooth separation of the rubber products. Attached Figure Description

Detailed Implementation

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0028] Please see Figure 1-3As shown, a skeleton detection device for a rubber product with a skeleton includes a lifting mechanism 1 and a height limiting mechanism 2 and a width limiting mechanism 3 for sorting the rubber product. The lifting mechanism 1 includes a feeding box 11 and a belt elevator 12. The feeding box 11 is located above one end of the belt elevator 12, and the bottom of the feeding box 11 is connected to the belt elevator 12. The rubber product is placed in the feeding box 11 and lifted to a certain height by the belt elevator 12. A horizontal conveyor belt 6 is provided on one side of the lifting mechanism 1. One end of the horizontal conveyor belt 6 is connected to one end of the belt elevator 12 through a discharge pipe 13. The rubber product lifted to a certain height enters the upper surface of the horizontal conveyor belt 6 through the discharge pipe 13.

[0029] Along the transmission direction of the horizontal conveyor belt 6, a height limiting mechanism 2 and a width limiting mechanism 3 are sequentially arranged. At the other end of the horizontal conveyor belt 6, a belt weighing system 4 is provided, and at the tail end of the belt weighing system 4, a selective separation mechanism 5 for separating rubber products is connected.

[0030] Specifically, the height limiting mechanism 2 is located on the side of the horizontal conveyor belt 6. The height limiting mechanism 2 includes a vertical mounting plate 21. A lifting module 22 is installed on one side of the vertical mounting plate 21. A height limiting drive motor is fixedly installed on the output end of the lifting module 22. A height limiting pusher 23 is fixedly installed on the output end of the height limiting drive motor. The height limiting pusher 23 is located directly above the horizontal conveyor belt 6. The height limiting pusher 23 is an impeller-shaped structure with multiple grid plates evenly arranged in the circumferential radial direction. In another embodiment, a height-adjustable stop bar can be used directly for height limiting. Since rubber products are elastic, directly using a height stop bar can easily cause more than one rubber product to get stuck between the height stop bar and the horizontal conveyor belt 6, thereby causing wear to the rubber product and the horizontal conveyor belt 6.

[0031] The height-limiting pusher 23 is used to push the material while blocking it. The distance between the height-limiting pusher 23 and the upper surface of the horizontal conveyor belt 6 is adjusted by the lifting module 22. The height-limiting drive motor drives the height-limiting pusher 23 to rotate continuously. The grid plate on the height-limiting pusher 23 is used to block and push the material. The tangential direction of the movement of the grid plate near the horizontal conveyor belt 6 is opposite to the conveying direction of the horizontal conveyor belt 6, which effectively limits the height of the rubber products, so that the rubber products pass through the height-limiting mechanism 2 in a single layer without being stacked in the height direction.

[0032] The width limiting mechanism 3 includes a horizontal mounting plate 31 positioned directly above the horizontal conveyor belt 6. A transverse shift module 32 is mounted on the top of the horizontal mounting plate 31. A speed regulating motor is mounted on the output end of the transverse shift module 32. A width limiting turntable 34 is fixedly mounted on the output end of the speed regulating motor. The width limiting turntable 34 is offset relative to the centerline of the horizontal conveyor belt 6. The center of the width limiting turntable 34 is projected onto the edge of the horizontal conveyor belt 6. The tangential velocity direction of the outermost end of the width limiting turntable 34 near the other edge of the horizontal conveyor belt 6 is consistent with the conveying direction of the horizontal conveyor belt 6. The distance between the width limiting turntable 34 and the edge of the horizontal conveyor belt 6 can be controlled by the transverse shift module 32. This distance is the width of the passage through which the rubber product passes.

[0033] When in use, when the rubber products reach the position of the width limiting turntable 34 through the height limiting mechanism 2, the rubber products pass through the channel in an orderly manner under the combined action of the conveying speed of the horizontal conveyor belt 6 and the rotation speed of the width limiting turntable 34. There is no baffle on one side edge of the horizontal conveyor belt 6 between the height limiting mechanism 2 and the width limiting mechanism 3, but an overflow slide plate 8 is inclined. The other end of the overflow slide plate 8 extends into the feed box 11. When a large number of rubber products accumulate between the height limiting mechanism 2 and the width limiting mechanism 3, the excess rubber products can flow back into the feed box 11 through the overflow slide plate 8 and be lifted again by the lifting mechanism 1 and enter the horizontal conveyor belt 6.

[0034] A rotating disk 37 is rotatably mounted on the bottom of a horizontal mounting plate 31. A synchronous pulley 36 is coaxially mounted on the bottom of the rotating disk 37. The synchronous pulley 36 is connected to a rotary motor 33 via a synchronous belt with a tensioning structure. A telescopic groove is provided on the rotating disk 37, and a telescopic rod 38 is slidably mounted in the telescopic groove. A rolling wheel 39 is rotatably mounted on the other end of the telescopic rod 38 away from the rotating disk 37. An intermittent turntable 310 is provided on one side of the rotating disk 37. The intermittent turntable 310 is rotatably connected to the horizontal mounting plate 31. Multiple intermittent mating grooves 312 are evenly provided at equal angles on the outer side of the intermittent turntable 310. In addition, U-shaped grooves are evenly provided on the upper part of the intermittent turntable 310. The number of U-shaped grooves is the same as the number of intermittent mating grooves 312. A toggle pin 311 is adjustablely fixed in the U-shaped groove by bolts. The rolling wheel 39 cooperates with the intermittent mating grooves 312 to drive the intermittent turntable 310 to rotate intermittently.

[0035] On one side of the intermittent turntable 310, there is also a mounting pin. The mounting pin is rotated and installed on the bottom of the horizontal mounting plate 31 by a torque spring. A connecting strip 313 and a stop strip 314 are fixedly installed on the outside of the mounting pin respectively. The connecting strip 313 and the stop strip 314 form a certain angle and the angle is adjustable.

[0036] At the bottom of the horizontal mounting plate 31, guide plate 1 351 and guide plate 2 352 are also fixedly installed. Guide plate 1 351 and guide plate 2 352 cooperate with each other to form an opening and closing channel for controlling the rubber products to pass through at equal intervals. The end of the baffle 314 is set at the outlet of the opening and closing channel.

[0037] During operation, the rubber products, after passing through the width limit, are conveyed into the opening and closing channel by the horizontal conveyor belt 6. The rotating disk 37 rotates under the drive of the synchronous wheel, so that the rolling wheel 39 engages with multiple intermittent mating grooves 312 on the intermittent turntable 310, causing the intermittent turntable 310 to rotate intermittently. The actuating pin 311 installed on it can actuate the connecting strip 313, thereby causing the stop strip 314 to rotate around the mounting column, releasing the closed state of the opening and closing channel. Subsequently, under the action of the torque spring, the closing control of the opening and closing channel is restored. This operation allows the rubber products to enter the subsequent belt weighing system 4 in an equidistant and orderly manner.

[0038] The belt weighing system 4 includes two belt weighing mechanisms of different lengths. The shorter belt weighing mechanism first weighs a single rubber product that has been distance-controlled, and then it enters the longer belt weighing mechanism. The longer belt weighing mechanism weighs multiple rubber products. The data is compared from two dimensions: single weighing and multiple weighing and averaging. When the weighing deviation exceeds the set value, the abnormal rubber products marked by the selection separation mechanism 5 are screened and removed.

[0039] Specifically, the separation mechanism 5 includes a pusher plate and a pusher cylinder that drives the pusher plate to move. Abnormally weighed rubber products and normal rubber products enter the collection box 1 71 and collection box 2 72 respectively.

[0040] In use, the rubber products in the feed box 11 are lifted to a certain height by the belt elevator 12, and then enter the horizontal conveyor belt 6 through the discharge pipe 13 for conveying. The height limiting drive motor drives the height limiting pusher 23 to rotate continuously. The grid plate on the height limiting pusher 23 is used to block and push the material. The tangential direction of the movement of the grid plate near the horizontal conveyor belt 6 is opposite to the conveying direction of the horizontal conveyor belt 6, which effectively limits the height of the rubber products.

[0041] When the rubber products passing through the height limiting mechanism 2 reach the position of the width limiting turntable 34, the combined action of the conveying speed of the horizontal conveyor belt 6 and the rotational speed of the width limiting turntable 34 causes the rubber products to pass through the channel in an orderly manner. The rubber products that have passed the width limit are conveyed into the opening and closing channel by the horizontal conveyor belt 6, and the rotating disk 37 rotates under the drive of the synchronous wheel. As a result, the rolling wheel 39 engages with the multiple intermittent mating grooves 312 on the intermittent turntable 310, causing the intermittent turntable 310 to rotate intermittently. The actuating pin 311 installed on it can actuate the connecting strip 313, thereby causing the stop strip 314 to rotate around the mounting column, releasing the closed state of the opening and closing channel. Subsequently, under the action of the torque spring, the closed control of the opening and closing channel is restored. This operation allows the rubber products to enter the subsequent belt weighing system 4 in an orderly manner at equal intervals.

[0042] The belt weighing system 4 uses two belt weighing mechanisms of different lengths to weigh rubber products individually and in combination. After data comparison, abnormal rubber products are screened and removed by the selection separation mechanism 5.
