Description

Technical Field

[0001] The present application relates to the technical field of rubber and plastic product processing, and in particular to a conveying and pushing device for rubber and plastic products. Background Art

[0002] After the rubber and plastic products are manufactured, they need to be tested to ensure that the quality of the rubber and plastic products sold meets the standards. Before testing the rubber and plastic products, a material turning detection device is usually used to test the rubber and plastic products.

[0003] The flipping detection device usually includes a conveyor belt, a turning mechanism, a visual inspection mechanism and a return bin. The turning mechanism, the visual inspection mechanism and the return bin are arranged in sequence, and the rubber and plastic products are conveyed by the conveyor belt. During the conveying process, the turning mechanism turns over the rubber and plastic products with a small diameter at one end and a large diameter at the other end, so that the end with a larger diameter is stably clamped and turned over and straightened on the conveyor belt, and then stably conveyed to the visual inspection mechanism, so that the visual inspection mechanism can perform visual inspection on the rubber and plastic products that are stably placed. The conveyor belt is provided with a feed end and a discharge end, and the return bin is connected to the feed end and the discharge end of the conveyor belt. The operator will regularly conduct random inspections on the rubber and plastic products. If the rubber and plastic products that are missed by the visual inspection mechanism are found, the operator will put the missed rubber and plastic products into the return bin, and the missed rubber and plastic products will return to the feed end of the conveyor belt through the return bin for re-inspection.

[0004] The above-mentioned existing technical solutions have the following defects: in the absence of operator random inspection, the inaccurate placement of rubber and plastic products can easily lead to the rubber and plastic products being judged as unqualified before being detected and thus being rejected. The detection accuracy is not high, so there is room for improvement. Utility Model Content

[0005] In order to improve the accuracy of detection, the present application provides a conveying and pushing device for rubber and plastic products.

[0006] The present application provides a rubber and plastic product conveying and pushing device adopts the following technical solution:

[0008] By adopting the above technical scheme, the conveying and pushing device is installed on the material turning detection equipment. When the rubber and plastic product is conveyed on the material turning detection equipment, it first passes through the first sensor. The first sensor senses the passing of the rubber and plastic product and sends a confirmation signal to the controller. The rubber and plastic product continues to be conveyed through the second sensor. If the rubber and plastic product is not placed correctly, the height of the rubber and plastic product is not enough for the second sensor to sense it. The second sensor does not sense the rubber and plastic product, and the controller does not receive the confirmation signal of the second sensor. The controller controls the pushing mechanism to push the rubber and plastic product into the return bin and re-convey it to the material turning detection equipment for material turning detection; if the rubber and plastic product is placed correctly, the height of the rubber and plastic product can be sensed by the second sensor. The second sensor senses the rubber and plastic product and sends a confirmation signal to the controller. After receiving the confirmation signals of the first sensor and the second sensor, the controller determines that the rubber and plastic product has passed the detection, does not control the pushing mechanism to push the rubber and plastic product, and the rubber and plastic product is conveyed to the next process, which reduces the situation where the rubber and plastic product is judged as unqualified and rejected before being detected due to inaccurate placement of the rubber and plastic product, thereby improving the convenience and accuracy of detection.

[0012] By adopting the above technical solution, the driving cylinder drives the mounting block to move, the movement of the mounting block drives the adjustment plate to move, the movement of the adjustment plate drives the pusher to move, and the movement of the pusher pushes the rubber and plastic products into the return bin, thereby realizing the pushing operation of the rubber and plastic products, with a simple structure and a high degree of automation.

[0013] Preferably, an adjustment hole is provided on the adjustment plate, and the adjustment plate is fixed to the mounting block by bolts passing through the adjustment hole.

[0015] Preferably, a first waist-shaped hole is formed on the mounting frame, and the mounting frame is fixed to the frame by bolts passing through the first waist-shaped hole.

[0016] By adopting the above technical solution, the operator can adjust the position of the mounting frame relative to the frame by loosening the bolts, sliding the mounting frame and then tightening the bolts, thereby adjusting the distance between the pushing mechanism and the conveyor belt to adapt to rubber and plastic products of different sizes, further improving applicability and convenience.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The present application embodiment discloses a conveying and pushing device for rubber and plastic products. Figure 1 and Figure 2A conveying and pushing device for rubber and plastic products is installed on a material turning detection device, on which a conveying belt 1 is rotatably carried, and the conveying and pushing device is located on one side of the conveying belt 1. The conveying and pushing device includes a frame 2, on which a controller, a pushing mechanism 3, a first sensor 4 and a second sensor 5 are arranged, and a mounting frame 6 is fixed on the frame 2, the mounting frame 6 is arranged in an inverted L shape, and the mounting frame 6 is located on one side of the conveying belt 1 of the material turning detection device, and a first waist-shaped hole 7 is opened on the mounting frame 6, and the length direction of the first waist-shaped hole 7 is arranged perpendicular to the length direction of the conveying belt 1, and the mounting frame 6 is fixed to the frame 2 by bolts passing through the first waist-shaped hole 7, and the pushing mechanism 3 is installed on the mounting frame 6. The operator can adjust the position of the mounting frame 6 relative to the frame 2 by loosening the bolts, sliding the mounting frame 6, and then tightening the bolts, thereby adjusting the position of the pushing mechanism 3 relative to the conveying belt 1 to adapt to rubber and plastic products of different sizes. The first sensor 4 and the second sensor 5 are both fixed on the frame 2. In this embodiment, the first sensor 4 is a laser sensor, and the second sensor 5 is a capacitive sensor. The first sensor 4, the second sensor 5 and the mounting frame 6 are arranged in sequence along the conveying direction of the conveyor belt 1, and the sensing position of the second sensor 5 is higher than the sensing position of the first sensor 4. The first sensor 4, the second sensor 5 and the pushing mechanism 3 are all electrically connected to the controller. A return bin 8 is fixed on the side of the conveyor belt 1 away from the pushing mechanism 3, and the bin opening of the return bin 8 is arranged toward the conveyor belt 1. The controller is used to control the pushing mechanism 3 to push the rubber and plastic products into the return bin 8.

[0029] Correspondingly, when the rubber and plastic products are transported on the material turning detection device, they pass through the first sensor 4 and the second sensor 5 successively. The first sensor 4 senses the passing of the rubber and plastic products, and the second sensor 5 senses the height of the rubber and plastic products. When the first sensor 4 and the second sensor 5 sense the rubber and plastic products, they will send a confirmation signal to the controller. The placement of the rubber and plastic products will affect the height of the rubber and plastic products. If the rubber and plastic products are not placed correctly and there is a large difference in the height of the rubber and plastic products, the second sensor 5 cannot sense the passing of the rubber and plastic products and will not send a confirmation signal to the controller. If the controller only receives the confirmation signal of the first sensor 4 but not the confirmation signal of the second sensor 5, it will control the pushing mechanism 3 to push the rubber and plastic products into the return bin 8 and re-transport them to the material turning detection device for material turning detection; if the controller receives two confirmation signals from the first sensor 4 and the second sensor 5, it is judged that the rubber and plastic products have passed the detection, and the pushing mechanism 3 is not controlled to push the rubber and plastic products. The rubber and plastic products are transported to the next process, which reduces the situation where the rubber and plastic products are judged as unqualified and rejected before being detected due to the inaccurate placement of the rubber and plastic products, thereby improving the convenience and accuracy of the detection.

[0030] Furthermore, an adjustment frame 9 is installed on the frame 2, and the adjustment frame 9 is L-shaped. A second waist-shaped hole 10 is opened on the adjustment frame 9, and the length direction of the second waist-shaped hole 10 is vertically arranged. The second sensor 5 is fixed to the adjustment frame 9 by bolts passing through the second waist-shaped hole 10. When the position of the second sensor 5 needs to be adjusted, the operator can loosen the bolts on the second sensor 5, then slide the second sensor 5 vertically, and then tighten the bolts to fix the second sensor 5 to adjust the position of the second sensor 5 relative to the adjustment frame 9, thereby adjusting the height of the second sensor 5 to adapt to rubber and plastic products of different sizes, thereby improving applicability and convenience.

[0031] Specifically, the pushing mechanism 3 includes a driving cylinder 31 and a pushing assembly 32. The driving cylinder 31 is fixed on the mounting frame 6. The driving cylinder 31 is horizontally arranged. The piston rod of the starting cylinder is arranged toward the conveyor belt 1. The driving cylinder 31 is electrically connected to the controller. The pushing assembly 32 includes a mounting block 321, an adjustment plate 322 and a pushing piece 323. The mounting block 321 is fixedly connected to the piston rod of the driving cylinder 31. The adjustment plate 322 is vertically arranged. An adjustment hole 11 is provided on the adjustment plate 322. The length direction of the adjustment hole 11 is vertically arranged. One end of the adjustment plate 322 is fixed to the mounting block 321 by a bolt passing through the adjustment hole 11. The pushing piece 323 is fixed to the other end of the adjustment plate 322. When the size of the rubber and plastic product changes and the position of the pusher 323 needs to be adjusted, the operator can loosen the bolts on the adjustment plate 322, then vertically slide the adjustment plate 322, and then tighten the bolts to fix the adjustment plate 322 to adjust the position of the adjustment plate 322 relative to the mounting block 321, thereby adjusting the height of the pusher 323 to adapt to rubber and plastic products of different sizes.

[0032] Furthermore, the pusher 323 is tilted from the adjustment plate 322 toward the return bin 8, and the end of the pusher 323 is disposed toward the porthole of the return bin 8. The pusher 323 is tilted downward from the adjustment plate 322 toward the return bin 8, and the tilt angle is 20-45 degrees. The tilted pusher 323 causes the rubber and plastic product to be subjected to a downward force when being pushed, and is not easily bounced during the pushing process, further improving the stability of the pushing material. The end of the pusher 323 is provided with a bar tooth 12. The length direction of the bar tooth 12 is disposed toward the porthole of the return bin 8. The provision of the bar tooth 12 increases the friction force of the end of the pusher 323, making it not easy to slip when pushing the material, which is conducive to improving the stability of the pushing material.

[0033] The implementation principle of a conveying and pushing device for rubber and plastic products in the embodiment of the present application is as follows:

[0034] The conveying and pushing device is installed on the material turning detection device. When the rubber and plastic products are conveyed on the material turning detection device, they first pass through the first sensor 4. The first sensor 4 senses the passing of the rubber and plastic products and sends a confirmation signal to the controller. The rubber and plastic products continue to be conveyed through the second sensor 5. If the rubber and plastic products are not placed correctly, the height of the rubber and plastic products is not enough for the second sensor 5 to sense them. The second sensor 5 does not sense the rubber and plastic products and will not send a confirmation signal to the controller. If the controller does not receive the confirmation signal from the second sensor 5, the controller controls the pushing mechanism 3 to push the rubber and plastic products into the return bin 8 and re-convey them to the material turning detection device for material turning detection. If the rubber and plastic products are placed correctly, the height of the rubber and plastic products can be sensed by the second sensor 5. The second sensor 5 senses the rubber and plastic products and sends a confirmation signal to the controller. After receiving the confirmation signals from the first sensor 4 and the second sensor 5, the controller determines that the rubber and plastic products have passed the detection, does not control the pushing mechanism 3 to push the rubber and plastic products, and the rubber and plastic products are conveyed to the next process. This reduces the chances of rubber and plastic products being rejected as unqualified before being detected due to inaccurate placement of the products, thereby improving the convenience and accuracy of detection.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
