Description

Technical Field

[0001] The utility model relates to a belt detection device. Background Art

[0002] The belts produced need to be inspected for appearance before packaging to detect appearance defects and remove them in time before they enter the market. Conventional appearance inspection is done manually by random sampling. The belt is placed on a horizontal bar and manually rotated for inspection. However, as the market's requirements for quality are getting higher and higher, many belts need to be inspected 100%. Manual inspection is undoubtedly inefficient. At the same time, for the problems caused by the belt cords, since the outer layer of the cords is covered with a certain rubber layer, only the bulges caused by the overlapping of the cords that are large enough can be easily discovered manually. There are certain omissions in manual inspections, so it is necessary to improve the inspection efficiency of the belts while increasing the risk of missed inspections. Utility Model Content

The following is a specific and detailed description of the present utility model based on the drawings,

[0026] like Figure 1 to Figure 5 As shown, the utility model provides a belt testing device, including a stand 1 welded together by profiles. The stand 1 is placed in the operating room. Adjustable support feet can be used at the four corners to facilitate balance adjustment. In order to improve the stability of the equipment, a fixed seat can also be added near the bottom plate of the stand, and it can be fixed to the ground or other bases by bolts. The driving wheel assembly 3 is installed on the upper part of the stand, including a driving wheel 34 for driving the belt to be tested. The driving wheel and the second synchronous pulley 35 are installed at both ends of the same pulley shaft. The pulley shaft is fixed on the driving wheel mounting plate 30 through bearings. The driving wheel and the synchronous pulley are located on both sides of the driving wheel mounting plate 30. The driving wheel mounting plate 30 can be fixed on the stand directly or through a connecting plate, etc. The driving wheel is located on the working surface side of the stand, which is convenient for the installation of the belt to be tested. The second synchronous pulley 35 is located on the inner side of the stand. The driving wheel 34 is driven to rotate by the driving wheel motor 31. Specifically, the pulley is connected to the first synchronous pulley 33 through the synchronous belt 32, and the first synchronous pulley 33 is connected to the driving wheel motor 31 through the reducer. The driving wheel motor drives the first synchronous pulley 33 to operate, and the first synchronous pulley 33 drives the second synchronous pulley 35 to rotate through the synchronous belt 32, thereby driving the driving wheel to rotate. The driving wheel motor 31 is fixed to the stand through a bracket.

[0027] In order to facilitate the installation of the belt and use the same equipment for testing of belts of different lengths, and increase the flexibility of the equipment, a mobile platform 6 is arranged below the driving wheel assembly 3. The axes of the driving wheel and the driven wheel 7 are arranged in parallel when installed on the mobile platform 6. The mobile platform 6 is used to adjust the spacing between the driving wheel and the driven wheel 7. The mobile platform 6 includes a screw assembly, two first slide rails 61 distributed on the left and right sides of the screw, four first sliders 62 and a mobile plate 63. The two first slide rails are installed on the stand 1 in parallel with the screw 64. The four first sliders 62 are arranged in parallel in two groups on the left and right sides and fixed on the same side of the mobile plate 63. The four first sliders correspond to the two first slide rails respectively. The two sliders on the same slide rail are arranged up and down, and the side of the slider away from the slide rail is slidably connected to the first slide rail. The mobile plate 63 is fixed to the screw flange 65 of the screw assembly. The two ends of the screw 64 are installed on the stand 1 through the screw bearings 66 of the screw seat, and one end of the screw is connected to the drive motor. Specifically, the common connection method in the prior art may be used, such as connecting with the screw drive motor 67 through a coupling, a reducer, and driving the screw flange 65 to move along the screw 61, thereby driving the moving plate 63 to move.

[0028] In order to facilitate the rapid transfer of the tested belt from the testing position to the material rack, a disassembly assembly 4 is also provided. The disassembly assembly 4 includes a push rod, a push plate, a guide member and a push plate cylinder. The push plate is arranged on the outer circumference of the driving wheel. One end of the push rod is connected to the push plate cylinder and the other end is connected to the push plate. The push rod or the push plate is slidably installed in the guide member. The guide member is fixedly installed on the driving wheel mounting plate 30. The detection camera 2 is fixedly installed above the driving wheel. The driving wheel drives the belt to rotate one circle at a set speed. The detection camera 2 takes pictures of the belt in real time and outputs the test results. The detection camera 2 is a CCD camera, which is connected to the control system and outputs the data to the industrial computer for storage, which is convenient for later tracing.

[0029] like Figure 2 As shown, the push plate 41' is divided into two, and the shape is an arc plate consistent with the appearance of the driving wheel 34. Here, an arc-shaped triangular structure is adopted, and the width of the side in contact with the belt is slightly narrower. The push plate 41' is arranged on the outer circumference of the driving wheel and is distributed as far as possible. The outer end of the push plate is radially located within the thickness of the belt, so that the push plate 41' can push the belt out of the driving wheel after moving. The inner end of the push plate 41' is connected to the push rod 43', and the other end of the push rod 43' is connected to the cylinder rod of the push rod cylinder 42'. Usually, the push rod and the cylinder rod are connected by a floating joint. The push rod 43' or the push plate 41' is installed in a guide member, such as a sliding bearing or a through hole. In this embodiment, the two push plates 41' can be respectively controlled by two push rod cylinders 42', and the push rod cylinder 42' can be a needle cylinder. The guide member is a corresponding through hole on the driving wheel mounting plate 30, which guides and slides the push plate 41'. The push plate cylinder 42' can be directly mounted on the stand 1, or fixed on the stand 1 via a transition plate.

[0030] To facilitate removal, the push plate can be a semicircular arc plate surrounding the outer circumference of the driving wheel, such as Figure 3 As shown, if it is arranged on the upper or lower part of the driving wheel, the inner side of the push plate 41 is connected with two or more push rods 43, and the other end of the push rod is fixed on the push rod connecting plate (not shown), and the push rod connecting plate is connected to the push plate cylinder 42, and the push plate 41 is pushed by the same cylinder to move, so as to maintain the consistency of movement. The push rod 43 is supported on the driving wheel mounting plate 30 by the push rod slide 44, and the push rod slide is a sliding bearing. In order to ensure the sliding flexibility of the push rod 43, the cylinder rod is connected to the push plate connecting plate through a floating joint, and the push plate cylinder 42 pushes the connecting plate to move, and the connecting plate drives the push rod 43 to move along the push rod slide 44, thereby pushing the push plate 41, and the push plate 41 pushes the belt 5 from the driving wheel and detaches from the driving wheel.

[0031] In order to ensure that the belt 5 is tensioned between the two wheels, a tensioning assembly 8 is also provided. After the mobile platform is fixed, the position of the driven wheel 7 relative to the driving wheel is appropriately adjusted to tension the belt. The tensioning assembly 8 includes a group of tensioning cylinders 84, a tensioning base plate 81 for fixing the driven wheel 7, a pulling block 85 for pulling the tensioning base plate 81 to move relative to the moving plate 63, and a sliding mechanism. The sliding mechanism is installed on the moving plate, and the tensioning base plate 81 is pulled to move along the sliding mechanism by the pulling block 85. Specifically, the tensioning base plate 81 is installed on one side of the working surface of the moving plate, and the driven wheel 7 is fixed on one side of the working surface of the tensioning base plate through a seat bearing 71, and is arranged coplanar with the inner side surface of the driven wheel 7. The sliding mechanism includes two second slide rails 83 installed in parallel on the moving plate and four second sliders 82 corresponding to the second slide rails 83, which are used for the tensioning base plate to slide up and down relative to the moving plate. Two tensioning cylinders 48 are provided on the non-working surface side of the moving plate, and the cylinder rod of the tensioning cylinder 84 is connected to the pulling block 85, and one side of the pulling block 85 is fixedly connected to the tensioning base plate 81. The replaceable pulling block and the tensioning base plate may also be an integral structure.

[0032] In order to simplify the loading structure during automatic loading and facilitate the installation of the belt, the driven wheel 7 can be set as a cylindrical structure with a longer axial length than the driving wheel to prevent the driving wheel from not being installed on the driven wheel 7 or slipping after being put on the belt, resulting in installation failure.

[0033] In order to facilitate the classified storage of the belts after inspection, a material unloading component 9 is also included. The material unloading component 9 is installed above the driving wheel and moves between the driving wheel and the material rack so as to place the inspected belt on the corresponding material rack. The material unloading component 9 includes a material unloading mounting bracket 91, a material unloading mounting plate 92, a material unloading moving mechanism and a shifting rod 96. The material unloading component is fixed to the stand through the material unloading mounting bracket 91. The material unloading mounting bracket 91 is installed on the front side of the stand 1 and is located above the driving wheel. The moving mechanism can adopt a magnetic rodless cylinder 93. The magnetic rodless cylinder 93 is fixed to the material unloading mounting bracket 91 through the material unloading mounting plate 92. The shifting rod assembly is installed on the slider of the magnetic rodless cylinder 93 and is driven to move by the slider. The lever assembly includes a lever mounting bracket 97, a lever shaft 99, and a double-acting cylinder 94. The top surface of the lever mounting bracket 97 is fixed to the slider of the magnetic rodless cylinder 93 through a connecting plate. The lever 96 is provided with an axial hole, and the lever shaft 99 is installed in the axial hole. The lever 96 is rotatably fixed to the lower end of the lever mounting bracket through the lever shaft 99. One end of the lever 96 is suspended for conveying the belt, and the other end is hingedly connected to the cylinder rod of the double-acting cylinder 94 through a double elbow joint 95, so that the lever forms a lever structure. The action of the double-acting cylinder 94 realizes the upward or downward warping around the lever shaft, so that the belt is suspended on the lever or slides to the material rack. The other end of the double-acting cylinder 94 is fixed to the upper end side wall of the lever mounting bracket by hingedly connecting with the mounting seat, so as to realize the fixation of the double-acting cylinder 94.

[0034] In order to realize the classified storage of qualified and unqualified belts after inspection, a swing cylinder 98 is also installed between the lever mounting bracket and the magnetic rodless cylinder 93. One side of the swing cylinder 98 is installed on the slider of the magnetic rodless cylinder 93, and the upper end face of the lever mounting bracket is installed on the end face of the rotating shaft of the swing cylinder 98. The circumferential rotation of the lever is realized to realize the classified transportation and storage of the belts. Qualified belts are placed on the qualified material rack 10' on one side, and unqualified belts are placed on the unqualified material rack 10 on the other side.

[0035] For safety reasons, protective plates 11 are provided around the stand 1.
