Description

Technical Field

[0001] The utility model relates to the field of rubber machinery, in particular to a film detection device. Background Art

[0002] In the fine production process of rubber products, the rubber mixing link plays a crucial role. The purity and quality of the rubber compound during the rubber mixing process directly determine the performance and quality of the final product. Therefore, strict detection of the rubber compound before rubber mixing is a key step to ensure the smooth progress of the production process and the stable and reliable quality of the product.

[0003] In the traditional rubber mixing feeding process, the detection of the rubber compound mainly relies on manual visual inspection and tactile inspection. However, this method has many deficiencies. Especially for the tiny or hidden metal sundries mixed in the rubber compound, it is often difficult for manual detection to accurately identify them. Once these metal sundries are fed into the rubber mixer with the rubber compound, they will have unforeseen effects during the rubber mixing process. The presence of metal sundries will not only cause a sudden increase in the transverse pressure of the rubber mixer, affecting the rubber mixing effect, but more seriously, they may seriously damage the rubber mixer itself and even cause production accidents, bringing immeasurable losses to the enterprise.

[0004] Although there have been some detection measures for metal sundries in the rubber compound, there are still many problems. For example, when the rubber compound sent from the internal mixer is transported to the subsequent work section, although it will pass through a metal detector installed on the conveyor belt for detection, when it is detected that the rubber compound contains metal impurities, the usual practice is to stop the conveyor belt and then rely on manual cutting. This processing method not only has low efficiency, but the stoppage of the conveyor belt will cause the main machine production line to slow down or lack materials, affecting the operation efficiency of the entire production line. And it is difficult to cut the cold film manually, the operation is inconvenient, and it is easy to make mistakes, with many potential hazards. Content of the Utility Model

[0060] Please refer to Figures 1 to 8 .

At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear description and are not used to limit the implementation scope of the present utility model. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the implementable scope of the present utility model.

[0061] Such as Figures 1 - 3As shown in the figure, the utility model provides a film detection device, which at least includes: a support frame 1, a transmission mechanism 2, a detection component 5, a cutting component 4 and a power component 6. Among them, the support frame 1 is used to support the transmission mechanism 2. Two opposite sides of the support frame 1 are provided with two horizontally arranged fixed grooves 11 for providing a movement track for the transmission mechanism 2. There are two transmission mechanisms 2, and the two transmission mechanisms 2 are symmetrically arranged on the support frame 1. The transmission mechanism 2 is responsible for transporting the rubber material to the detection area. Each transmission mechanism 2 includes: a driving wheel shaft 21, a driven wheel 22, a transmission belt 23, a driven rod 24 and a cutting plate 25. Both ends of the driving wheel shaft 21 are located in the fixed groove 11. One end of the driving wheel shaft 21 passes through the fixed groove 11 and is connected with a first driving motor 26. Driven by the first driving motor 26, the driving wheel shaft 21 drives the transmission belt 23 to operate. Further, the driven wheel 22 is connected to the driving wheel shaft 21 through the transmission belt 23 to achieve power transmission. The driven wheel 22 is sleeved on the driven rod 24. Square limit blocks 241 matching the fixed groove 11 are arranged at both ends of the driven rod 24. The limit blocks 241 ensure that the driven rod 24 does not rotate with the rotation of the driven wheel 22. Further, the cutting plate 25 is fixedly connected to the driven rod 24 and is parallel to the transmission belt 23. In a preferred embodiment, the cutting plate 25 and the transmission belt 23 are on the same horizontal line to ensure that the rubber material on one side of the transmission mechanism 2 can smoothly fall onto the corresponding cutting plate 25 and finally enter the transmission belt 23 on the other side after being pushed by this transmission belt 23. The two transmission mechanisms 2 can move along the fixed groove 11. Specifically, a connecting rod 3 is respectively hinged to both sides of the driving wheel shaft 21 and both sides of the driven rod 24, and the other end of the connecting rod 3 is hinged to the cutting component 4. Further, the cutting component 4 is used for cutting the rubber material. The cutting component 4 is connected to the detection component 5, and the detection component 5 is used for detecting metal substances passing through on the transmission mechanism 2. When receiving the signal sent by the detection component 5, the cutting component 4 will be quickly activated to cut the rubber material containing metal debris. The connection between the cutting component 4 and the transmission mechanism 2 is realized through the connecting rod 3. When the cutting component 4 moves downward, the movement of the connecting rod 3 will drive the two transmission mechanisms 2 to move along both sides of the fixed groove 11, so as to ensure the accuracy and efficiency of cutting. The power component 6 is used to drive the cutting component 4 to move up and down.

[0062] As Figures 4 - 6As shown in the figure, specifically, the cutting assembly 4 includes: a housing 41, a telescopic plate 42, a cutter head 43, and a pressing rod 44. Fixed columns 411 are provided on both sides of the housing 41. The connecting rod 3 is hinged to the fixed columns 411. A spring is provided inside the housing 41. The telescopic plate 42 is nested inside the housing 41. The spring is located between the housing 41 and the telescopic plate 42. Two cutter heads 43 are detachably provided below both sides of the telescopic plate 42. The length of the cutter heads 43 matches the length of the cutting plate 25. Further, a pressing rod 44 is connected inside the housing 41. The pressing rod 44 passes through the telescopic plate 42. A limiting ring 441 is provided on the pressing rod 44. The top of the limiting ring 441 is not higher than the bottom of the housing 41 in the horizontal direction. In the normal state, the bottom end of the pressing rod 44 is not lower than the bottom end of the cutter head 43.

[0063] As Figures 7 - 8 shown in the figure, in this device, the detection assembly 5 includes: a detection door 51 and a metal detector 52. The detection door 51 is located on both sides of the support frame 1, forming a detection channel through which the rubber compound is transported. A metal detector 52 is provided at the top of the detection door 51. When the metal detector 52 detects that the rubber compound contains metal debris, it will immediately send out a signal to trigger the subsequent cutting action.

[0064] Further, a plurality of movable slots 511 are provided on both sides of the detection door 51. A spring is provided in each movable slot 511. A plurality of flanges 412 matching the movable slots 511 are provided on the housing 41. The flanges 412 are located above the spring. When the cutting assembly 4 moves downward for cutting, the flanges 412 will compress the spring. When the cutting is completed, the spring will cause the cutting assembly 4 to quickly reset. Further, the power assembly 6 includes: an eccentric wheel 61, a transmission rod 62, and a second driving motor 63. The transmission rod 62 passes through the detection door 51 at both ends. An eccentric wheel 61 is provided on the transmission rod 62. The eccentric wheel 61 abuts against the top of the housing 41. A second driving motor 63 is provided on one side of the transmission rod 62.

[0065] In one embodiment, a collection box 7 is provided below the support frame 1. The collection box 7 is located directly below the cutting assembly 4, so that the cut rubber compound can directly fall into the collection box 7.

[0066] A disc-shaped pressing plate 442 is provided at the bottom of the pressing rod 44, which can more easily push out the cut rubber compound.

[0067] Operation process: When the rubber compound before rubber mixing and feeding is transported to the side transmission mechanism 2 of the device through an external conveying device, the transmission mechanism 2 drives the rubber compound to move forward. The rubber compound passes through the detection door 51 during the conveying process.

[0068] Once the metal detector 52 detects that the rubber compound contains metal substances at the detection door 51, it will immediately send out a signal. This signal will be received by an external control system, and the control system will then react and drive the second driving motor 63 to start running.

[0069] The rotation of the second drive motor 63 drives the transmission rod 62 to rotate, thereby causing the eccentric wheel 61 to rotate. The rotation of the eccentric wheel 61 generates a downward pressure on the outer shell 41, causing the outer shell 41 to start moving downward. The downward movement of the outer shell 41 is linked to the telescopic plate 42, so the telescopic plate 42 will also move downward accordingly.

[0070] During the downward movement of the telescopic plate 42, due to the action of the connecting rod 3, the two symmetrically arranged transmission mechanisms 2 move along both sides of the fixed groove 11, providing space for subsequent cutting operations. When the cutter head 43 below the telescopic plate 42 contacts the rubber material, the cutting plate 25 has moved below the cutter head 43, and the cutter head 43 starts to cut the rubber material containing metal.

[0071] After cutting is completed, the outer shell 41 continues to move downward. At this time, the pressure rod 44 inside the outer shell 41 also starts to move downward. The downward movement of the pressure rod 44 presses out the cut rubber material from between the two cutting plates 25, causing it to fall into the collection box 7.

[0072] After the cutting and pressing actions are completed, the eccentric wheel 61 starts to rotate and reset. With the reset of the eccentric wheel 61, the spring in the movable groove 511 uses its elastic restoring force to help the cutting assembly 4 return to its initial position, preparing for the next cutting operation.

[0073] In summary, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0074] The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
