[0009] Preferably, the opening of the upper pull plate faces upward, the opening of the lower pull plate faces downward, the upper pull plate is located below the placement cylinder, and the push plate is located below the placement cylinder.

[0010] Preferably, the upper pull plate has an inclined surface in the middle, and the inclined surface is inclined downward.

[0011] Preferably, a counterweight is connected to the lower part of the pull plate near the connecting block.

[0012] Preferably, the upper connecting block has a movable groove corresponding to the position of the gear, and the gear is movably connected in the movable groove. The upper connecting block has a sliding groove corresponding to the position of the gear, and the rack is intermittently slidably connected in the sliding groove.

[0013] Preferably, the second baffle has symmetrically arranged chamfers at the end near the placement cylinder.

[0014] Preferably, the vertical moving mechanism includes two first sliders, which are respectively connected to the middle of two connecting blocks. A first slide rail is provided in the detection box at the position corresponding to the first slider. Both first sliders are slidably connected in the first slide rail. A bidirectional lead screw is rotatably connected in the first slide rail. The two connecting blocks are threadedly connected to the bidirectional lead screw. The upper end of the bidirectional lead screw passes through the first slide rail and is connected to a first motor fixed to the upper surface of the first slide rail.

[0015] Preferably, the horizontal moving mechanism includes two second sliders, both of which are connected to the side of the first slide rail away from the connecting block. The detection box is connected to symmetrically arranged second slide rails corresponding to the positions of the second sliders. The second sliders are slidably connected in the second slide rails. One of the second slide rails is rotatably connected to a one-way screw. One of the second sliders is threadedly connected to the one-way screw. The end of the one-way screw away from the placement cylinder passes through the second slide rail and is connected to a second motor fixed to the side of the second slide rail.

[0016] Preferably, a positioning rod is connected inside another second slide rail, and another second slider is slidably connected to the positioning rod.

[0017] The beneficial effects of this utility model are:

[0018] The annular rubber product is placed from above the placement cylinder. The first baffle blocks the product. When strength testing is required, the second motor is activated, causing the one-way screw to rotate. This rotation moves the second slider and the first slide rail, which in turn moves the connecting block. The connecting block then moves the push plate and the second baffle closer to the placement cylinder. During this movement, the push plate contacts the first baffle and pushes it into the housing. As the first baffle enters the housing, it compresses the spring, causing it to contract and store its restoring force. The second baffle then inserts into the housing during its movement. Inside the hole, the bottom ring-shaped rubber product is separated from the other ring-shaped rubber products, with the bottom ring-shaped rubber product positioned above the first baffle and the other ring-shaped rubber products positioned above the second baffle. After the pusher plate completely pushes the first baffle into the outer shell, the bottom ring-shaped rubber product is no longer obstructed and will fall under its own weight. At this time, the upper and lower pull plates will be positioned directly below the placement cylinder due to the movement of the connecting block. After falling, the bottom ring-shaped rubber product will first fall into the upper pull plate and eventually be positioned between the upper and lower pull plates under the action of gravity, achieving the purpose of automatic feeding, reducing manual operation, and improving detection efficiency.

[0019] After the bottom annular rubber product falls, the second motor is restarted, causing the first slide rail to move away from the placement cylinder and out of contact with the rack. This movement of the first slide rail causes the second baffle to move out of the insertion hole, simultaneously moving the push plate away from the first baffle. Under the spring's restoring force, the first baffle slides out of the outer casing and returns to its position below the placement cylinder to block the annular rubber product. After the upper and lower pull plates have moved, the first motor is restarted, driving the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the two first sliders to move away from each other, thus moving the upper and lower pull plates away from each other. During this process of moving away from each other, the strength of the annular rubber product can be tested. After the test is completed, the second... One motor reverses, causing the upper and lower pull plates to move closer together, restoring the ring-shaped rubber product to its original shape. After the ring-shaped rubber product is restored, the second motor is restarted, causing the first slide rail to move closer to the rack. During the movement of the first slide rail, the rack enters the connecting block located above and meshes with the gear, causing the gear to rotate. After the gear rotates 180°, the first slide rail stops moving. At this time, the tilt direction of the inclined surface will become upward. Under the action of its own gravity, the ring-shaped rubber product will fall away from the connecting block, thus achieving the purpose of unloading. This reduces manual operation and improves inspection efficiency. A collection box is set in the corresponding position in the inspection box to collect the inspected ring-shaped rubber products.

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0035] Please see Figure 1 - Figure 7 As shown, a strength testing device for processing rubber parts includes a testing box 1, which is used to assist in testing the strength of rubber products.

[0036] The upper part of the testing box 1 is connected to a through placement cylinder 2, which is used to place ring-shaped rubber products.

[0037] Inside the testing box 1, a first baffle 21 is provided below the placement cylinder 2. The first baffle 21 is used to block the annular rubber product inside the placement cylinder 2 and prevent the annular rubber product from falling out of the placement platform.

[0038] Inside the testing box 1, at the position corresponding to the first baffle 21, there is a shell 22. The first baffle 21 is slidably connected inside the shell 22, and the shell 22 is used to house the first baffle 21.

[0039] A plurality of evenly arranged springs 23 are connected between the outer casing 22 and the first baffle 21, and the springs 23 are used to reset the first baffle 21.

[0040] Inside the testing box 1, there are symmetrically arranged connecting blocks 3 at the positions corresponding to the placement cylinder 2. The two connecting blocks 3 are arranged one above the other and are used to connect the upper pull plate 3231 or the lower pull plate.

[0041] The upper connecting block 3 is rotatably connected to a U-shaped upper pull plate 3231 via a rotating rod 33 on the side below the placement cylinder 2. The lower connecting block 3 is connected to a U-shaped lower pull plate on the side above the placement platform. The upper pull plate 3231, together with the lower pull plate, is used to test the strength of the ring-shaped rubber product.

[0042] The opening of the upper pull plate 3231 faces upward, and the opening of the lower pull plate faces downward. This arrangement ensures the stability of the annular rubber product during strength testing and prevents it from falling off the upper pull plate 3231 and the lower pull plate.

[0043] The upper pull plate 3231 is located below the placement cylinder 2. This arrangement ensures that the annular rubber product can fall into the upper pull plate 3231.

[0044] Please see Figure 5 As shown, the upper pull plate 3231 has an inclined surface 311 in the middle. The inclined surface 311 is inclined downward. By setting the inclined surface 311, the position of the annular rubber product can be determined when the strength test is performed, so as to avoid the movement of the annular rubber product affecting the test. At the same time, by setting the inclined surface 311 to a downward state, after the feed plate rotates 180°, the inclined surface 311 will become an upward state. Under the action of its own gravity, the annular rubber product will fall away from the connecting block 3, thus achieving the purpose of unloading.

[0045] A counterweight 312 is connected to the lower part of the upper pull plate 3231 near the connecting block 3. The counterweight 312 is used to stabilize the upper pull plate 3231 so that the opening direction of the upper pull plate 3231 is always upward.

[0046] A gear 34 is connected to the outside of the rotating rod 33. The gear 34 is used to assist in rotating the upper pull plate 3231.

[0047] The connecting block 3 located above has a movable groove 35 at the position corresponding to the gear 34. The gear 34 is movably connected in the movable groove 35, and the movable groove 35 ensures that the gear 34 can rotate.

[0048] Inside the testing box 1, a rack 36 is connected to the position corresponding to the gear 34. The gear 34 and the rack 36 work together, and the rack 36 is used to drive the gear 34 to rotate.

[0049] The upper connecting block 3 has a groove 37 at the position corresponding to the gear 34. The rack 36 is intermittently slidably connected in the groove 37. By opening the groove 37, the rack 36 can mesh with the gear 34.

[0050] A push plate 4 is connected to the side of the connecting block 3 located above, near the placement cylinder 2, corresponding to the position of the first baffle 21. The push plate 4 is used to push the first baffle 21 into the outer shell 22.

[0051] The push plate 4 is located below the placement cylinder 2. This arrangement ensures that the push plate 4 can push the first baffle 21.

[0052] The connecting block 3 located at the top is connected to a second baffle 41 on the side away from the placement cylinder 2. The placement cylinder 2 has an insertion hole 42 at the position corresponding to the second baffle 41. The second baffle 41 is intermittently inserted into the insertion hole 42. The second baffle 41 is used to separate the bottom ring rubber product from other ring rubber products and to support the ring rubber product. Through the cooperation of the first baffle 21 and the second baffle 41, it can be ensured that only one ring rubber product falls out of the placement cylinder 2 at a time.

[0053] The second baffle 41 has symmetrically arranged chamfers 411 at one end near the placement cylinder 2. The chamfers 411 are used to assist the second baffle 41 in being inserted between the two annular rubber products, so that the second baffle 41 can be inserted between the two annular rubber products more quickly and accurately.

[0054] A vertical moving mechanism is provided on the side of the two connecting blocks 3 away from the upper pull plate 3231. The vertical moving mechanism is used to detect the strength of the ring-shaped rubber product.

[0055] The vertical movement mechanism includes two first sliders 5, which are respectively connected to the middle of two connecting blocks 3. A first slide rail 51 is provided in the detection box 1 corresponding to the position of the first sliders 5. Both first sliders 5 are slidably connected in the first slide rail 51. The first sliders 5 cooperate with the first slide rail 51 to initially define the position of the two connecting blocks 3.

[0056] A bidirectional lead screw 52 is rotatably connected inside the first slide rail 51. Two connecting blocks 3 are threadedly connected to the bidirectional lead screw 52. Through the cooperation of the bidirectional lead screw 52, ​​the two connecting blocks 3 can move closer to or further away from each other.

[0057] The upper end of the bidirectional lead screw 52 passes through the first slide rail 51 and is connected to the first motor 53 fixed to the upper surface of the first slide rail 51. The first motor 53 is used to drive the bidirectional lead screw 52 to rotate.

[0058] A horizontal moving mechanism is located away from the connecting block 3 in the vertical moving mechanism. The horizontal moving mechanism is used for loading and unloading annular rubber products.

[0059] The horizontal movement mechanism includes two second sliders 6, both of which are connected to the side of the first slide rail 51 away from the connecting block 3. The detection box 1 is connected to the second slide rails 61 that are symmetrically arranged, corresponding to the positions of the second sliders 6. The second sliders 6 are slidably connected in the second slide rails 61. The second sliders 6 cooperate with the second slide rails 61 to initially limit the position of the first slide rail 51.

[0060] One of the second slide rails 61 is rotatably connected to a one-way lead screw 62, and one of the second sliders 6 is threadedly connected to the one-way lead screw 62. Through the cooperation of the one-way lead screw 62, the position of the first slide rail 51 can be adjusted.

[0061] One end of the one-way lead screw 62 away from the placement cylinder 2 passes through the second slide rail 61 and is connected to the second motor 63 fixed to the side of the second slide rail 61. The second motor 63 is used to drive the one-way lead screw 62 to rotate.

[0062] Another second slide rail 61 is connected to a positioning rod 64, and another second slider 6 is slidably connected to the positioning rod 64. The positioning rod 64 is used to limit the position of the second slide rail 61 and prevent the second slide rail 61 from moving out of place.

[0063] Working principle:

[0064] When the annular rubber product is placed from above the placement cylinder 2, it will be blocked by the first baffle 21. When the strength of the annular rubber product needs to be tested, the second motor 63 is started, which drives the one-way screw 62 to rotate. The rotation of the one-way screw 62 drives the second slider 6 and the first slide rail 51 to move. The movement of the first slide rail 51 drives the connecting block 3 to move. The movement of the connecting block 3 drives the push plate 4 and the second baffle 41 to move closer to the placement cylinder 2. During the movement, the push plate 4 will contact the first baffle 21 and push the first baffle 21 into the outer shell 22. During the process of the first baffle 21 entering the outer shell 22, it will compress the spring 23. The spring 23 will contract and store the restoring force when compressed. The second baffle 41 moves... During the process, the ring-shaped rubber product is inserted into the socket 42 and separated from the other ring-shaped rubber products. The bottom ring-shaped rubber product is positioned above the first baffle 21, and the other ring-shaped rubber products are positioned above the second baffle 41. After the pusher 4 pushes the first baffle 21 completely into the outer shell 22, the bottom ring-shaped rubber product is no longer obstructed and will fall under its own weight. At this time, the upper pull plate 3231 and the lower pull plate will be positioned directly below the placement cylinder 2 under the action of the connecting block 3. After the bottom ring-shaped rubber product falls, it will first fall into the upper pull plate 3231 and eventually be positioned between the upper pull plate 3231 and the lower pull plate under the action of gravity. This achieves the purpose of automatic feeding, reduces manual operation, and improves detection efficiency.

[0065] After the bottom annular rubber product falls, the second motor 63 is restarted, causing the first slide rail 51 to move away from the placement cylinder 2 and not in contact with the rack 36. The movement of the first slide rail 51 causes the second baffle 41 to move out of the insertion hole 42, simultaneously moving the push plate 4 away from the first baffle 21. Under the restoring force of the spring 23, the first baffle 21 slides out from the outer shell 22, once again positioning itself below the placement cylinder 2 to block the annular rubber product. After the upper pull plate 3231 and the lower pull plate have moved, the first motor 53 is restarted. The first motor 53 drives the bidirectional lead screw 52 to rotate, causing the two first sliders 5 to move away from each other. This causes the upper pull plate 3231 and the lower pull plate to move away from each other. During this process of moving away from each other, the strength of the annular rubber product can be tested. After the test is completed, the first motor 53 is reversed, causing the upper pull plate 3231 and the lower pull plate to move closer to each other, restoring the annular rubber product to its original shape. After the annular rubber product is restored, the second motor 63 is restarted, causing the first slide rail 51 to move closer to the rack 36. During the movement of the first slide rail 51, the rack 36 will enter the connecting block 3 located above and mesh with the gear 34, causing the gear 34 to rotate. After the gear 34 rotates 180°, the first slide rail 51 stops moving. At this time, the tilt direction of the inclined surface 311 will become upward. Under the action of the annular rubber product's own gravity, it will fall away from the connecting block 3, thereby achieving the purpose of unloading the material, reducing manual operation, and improving the testing efficiency. A collection box is set in the corresponding position in the testing box 1 to collect the tested annular rubber products.
