Description

Technical Field

[0001] The invention relates to the technical field of salt spray testing equipment, and in particular to a salt spray testing device for cooking utensil production. Background Art

[0002] Salt spray test is an environmental test that uses salt spray environment conditions to test the corrosion resistance of products or metal materials. It is mainly divided into two categories, the first is the natural environment exposure test, and the second is the artificial simulated salt spray environment test.

[0003] The artificial simulated salt spray environment test uses a test equipment with a certain volume of space (such as a salt spray test chamber, etc.), and then places the object to be tested in it to measure the salt spray corrosion resistance quality of the object through the salt spray environment.

[0004] During the test, considering the diversity of items, the test time of different types of items varies greatly, so generally multiple items of the same kind are placed together in the equipment for salt spray testing. However, the production dates of the same items are also different. The same items with different production dates have different placement dates and removal dates. During the process, the test personnel will open the equipment many times to take out the items that have been tested, and then put in the newly produced items. The process is cumbersome. At the same time, the replacement and mixing of new and old items can easily cause confusion of items, resulting in confusion in the item test cycle and distortion of test data. At the same time, the salt spray test environment is corrosive to a certain extent. Even with protective equipment, long-term contact with the salt spray environment will still cause damage to the skin of the test personnel; if the salt spray test is stopped when the items are replaced, the test efficiency will be reduced and the test cycle will be extended. At the same time, the frequent start and stop of the equipment will cause changes in the salt spray environment, increasing the risk of data distortion; therefore, it is necessary to improve and optimize the existing technology.

After the switch door is closed or opened, the connection between the material exchange chamber 5 and the isolation chamber can be connected or cancelled; a conveyor belt with a circulating transmission arrangement is provided at the bottom of the isolation chamber, and the test sample is in the form of a plate, and its processing method is the same as that of the actual product.

[0027] In this embodiment, the number of clamping units is preferably two, and the two clamping units are symmetrically distributed on both sides of the test sample. Taking a single clamping unit as an example, the number of linkage rods 13, clamping rods 10 and extrusion wheels 11 in each clamping unit is two and symmetrically distributed; when in use, the test sample is placed in the card slot; with the help of the gravity support block 9 of the test sample itself, it slides downward and squeezes the elastic member 14, which is preferably a spring. The elastic member 14 contracts and accumulates elastic force, such as Figure 2 and Figure 3 As shown, when the support block 9 slides, it will drive the linkage rod 13 to slide synchronously, and at the same time, the linkage rod 13 starts to rotate on the support block 9; the linkage rod 13 drives the support rod 1 to start rotating on the linkage rod 13, and at the same time, the support rod 1 moves with the extrusion wheel 11 in the direction close to the test sample until the extrusion wheel 11 is in extrusion contact with the plane of the test sample, and the test sample is clamped and fixed with the help of two symmetrically distributed clamping rods 10 and the extrusion wheel 11, ensuring the verticality of the test sample and preventing the test sample from tilting to one side, resulting in different contacts between the two planes of the test sample and the salt spray, resulting in distortion of the test results.

[0028] After the test sample is fixed, the tray 7 is placed on the conveyor belt of the feed cabin. At this time, the conveyor belt is in a stationary state and the feed port is in a blocked state; then the switch door of the feed cabin is closed, the blockage of the feed port is cancelled, the conveyor belt of the feed cabin is started, the tray 7 is conveyed to the bracket 8, the feed port is blocked, and the operation of the conveyor belt is stopped to complete the closed feeding of the test sample to avoid direct contact with the environment in the test chamber 4. At this time, the discharge port is in a blocked state, and the atomizer head is turned on to spray salt mist to start the test; during the test, the gas in the isolation chamber is replaced by the exhaust system built into the isolation cabin 6 to complete the cleaning of the environment, and then the switch door of the feed cabin is opened to place the second test sample, and then the switch door is closed again to wait for the feeding of the second test sample.

[0029] Conversely, when the test sample is tested, an external force is applied to push the tray 7 to move to the discharge port, the switch door of the discharge chamber is closed, and then the blockage of the discharge port is cancelled, and an external force is applied to drive the tray 7 to slide into the isolation chamber of the discharge chamber, block the discharge port, and replace the gas in the isolation chamber of the discharge chamber through the exhaust system built into the isolation chamber 6 to complete the cleaning of the environment, and then open the switch door of the discharge chamber to take out the tray 7. During the operation, the isolation chamber 6 is used to realize the closed discharge of the test sample, so as to prevent the test personnel from directly contacting the environment in the test chamber 4, thereby protecting the test personnel.

[0030] At the same time, when the temperature of the test sample needs to be increased, the electrode heads 15 on the two clamping units can be connected to the positive and negative electrodes respectively to increase the temperature of the test sample; or the heating plate can be powered on, and the heating rod 16 can be an electric heating rod 16 in the prior art; the area where the test sample is located is heated by the heating rod 16 to meet the test requirements and improve the test efficiency and accuracy.

[0032] When in use, a number of grooves are provided on the bracket 8, and a side push frame 33 is rotatably arranged in each groove, and a side push wheel is rotatably arranged on the side push frame 33; a roller frame is arranged between two adjacent side push frames 33, and a roller is rotatably arranged on the roller frame; taking the isolation cabin 6 as the starting point, in this example, the number of grooves is preferably four, namely groove one, groove two, groove three, and groove four, respectively; multiple test samples can be placed for salt spray testing, and the test samples can be products produced at different times; a linkage unit is correspondingly arranged at each groove; the process is explained by taking the placement of the test sample in one groove as an example.

[0033] The test sample is placed on the tray 7 and fixed. At this time, a limiting area is formed between the limiting rod 17 and the protrusion 23. The end of the locking pin 19 away from the elastic member 22 is clamped in the limiting area, and the locking pin 19 is squeezed and contacted with the protrusion 23 and the limiting rod 17 at the same time; the tray 7 carrying the test sample passes through the isolation cabin 6 for feeding, and slides on the bracket 8 in the direction close to the groove until the bottom of the tray 7 is in rolling contact with the roller. At this time, the highest point of the roller is higher than the highest point of the side push wheel, and the side push wheel and the tray 7 are in a separated state; the tray 7 continues to approach the limiting rod 17 with the help of the rolling of the roller until it is squeezed and contacted with the buffer wheel 18 on the limiting rod 17. The outer edge of the buffer wheel 18 is provided with a rubber layer for buffering the impact inertia of the tray 7; the locking pin 19 is clamped to the limiting rod 17 to stop the tray 7, and the tray 7 stops at a groove.

[0034] When it is necessary to place the tray 7 into the groove 2, operate the linkage unit of the groove 1 to push the rotating shaft 20 in the direction close to the bracket 8, the sliding distance is A, the sliding key 1 43 approaches the locking groove 1 40 and is snapped into the locking groove 1 40, at this time, the sliding key 2 44, the sliding key 3 45 and the locking groove 2 41 are all in a separated state; the sliding key 46 and the locking groove 3 42 are in a separated state; then apply external force to drive the rotating shaft 20 to rotate a certain angle, the rotating shaft 20 will drive the sliding key 1 43, the sliding key 2 44, the sliding key 3 45 and the sliding key 4 46 to rotate at the same time; the sliding key 1 43 drives the triggering ring 21 to rotate synchronously, and when the triggering ring 21 rotates, the triggering inclined surface on it pushes the locking pin 19 to slide in the direction away from the limiting rod 17, and the locking pin 19 squeezes the elastic member 2 22 when sliding. The elastic member 2 22 is preferably a spring, and the elastic member 22 The force contracts and accumulates elastic force; as the locking pin 19 moves away from the limit rod 17 and the protrusion 23, when the shaft 20 stops rotating, the locking pin 19 stops sliding; at this time, an external force is applied to drive the roller, and the roller drives the tray 7 to slide in the direction close to the second groove, and the tray 7 squeezes the buffer wheel 18, and the buffer wheel 18 rotates on the limit rod 17. At the same time, with the help of the squeezing effect of the tray 7, the limit rod 17 rotates on the bracket 8 in the direction close to the locking pin 19, and the protrusion 23 on the limit rod 17 gradually approaches the locking pin 19. At this time, the limiting area gradually approaches the locking pin 19 until the locking pin 19 is clamped in the limiting area again. At this time, the direction of the limit rod 17 is parallel to the sliding direction of the tray 7; the tray 7 gradually slides from the first groove to the second groove, and similarly, the tray 7 is stopped with the help of the limit ring in the linkage unit at the second groove.

[0035] Taking groove one as an example, when the test sample is subjected to salt spray test, slide key one 43 is in a separated state from lock groove one 40, slide key two 44 and slide key three 45 are in a separated state from lock groove two 41, and slide key four 46 is in a separated turntable from lock groove three 42; when the test sample completes the test, at this time, the rotating shaft 20 is pushed in the direction close to the bracket 8, the sliding distance is B, and B is greater than A, at this time, the slide key one 43 passes through the lock groove one 40 and is still in a separated state; the slide key three 45 is clamped into the slide groove two 29, and the slide key two 44 is in a separated state from the slide groove two 29; the slide key four 46 is in a separated state from the slide groove three 34; then an external force is applied to drive the rotating shaft 20 to rotate, and the rotating shaft 20 drives the transmission sprocket one 26 to rotate synchronously, through the transmission Sprocket 1 26 and transmission assembly 1 27 drive the side stopper 25 to slide on the slide rail 24. The transmission assembly 1 27 is preferably a transmission chain 1, a transmission sprocket 3, a transmission shaft 1, a bevel gear pair, a transmission shaft 2, and a pendulum 1 that are commonly used in the prior art and are connected in sequence.

[0036] When the side stopper 25 rotates, it will synchronously slide in the second slide groove 29. With the help of the sliding connection of the second slide groove 29, the sliding member 28 slides in the direction away from the tray 7, and the sliding direction of the sliding member 28 is parallel to the sliding direction of the locking pin 19; the sliding member 28 is provided with a side guide surface 1, and when the sliding member 28 slides, the side guide surface 1 first comes into contact with the sliding member 2 30 by compression, and with the help of the compression of the side guide surface 1, the sliding member 2 30 slides in the direction away from the sliding member 28, and the sliding direction of the sliding member 2 30 is parallel to the sliding direction of the tray 7 from the groove 1 to the groove 2; when the sliding member 2 30 slides, it will gradually approach the sliding member 3 32, and with the help of the compression of the side guide surface 2 31, the sliding member 32 slides upward and gradually close to the side push frame 33, until the sliding member 32 and the side push frame 33 are in contact with each other. The side push frame 33 is pressed and contacted with the tray 7. With the help of the sliding member 32, the side push frame 33 rotates on the bracket 8 toward the direction close to the tray 7 until the side push wheel is pressed and contacted with the bottom of the tray 7. With the help of the side push wheel, the tray 7 is separated from the roller. As the side push frame 33 rotates, the side push frame 33 and the bracket 8 are in an angled state.

The bottom of the tray 7 is parallel to the side push frame 33. External force is applied to drive the side push wheel to rotate. At the same time, with the help of the weight of the tray 7, the tray 7 slides along the side push frame 33 away from the rotating shaft 20 until the tray 7 is separated from the groove 1 and moves to the side of the bracket 8 opposite to the groove 1, completing the separation of the tray 7 from the groove 1. After the external force is continued to be applied to drive the rotating shaft 20 to rotate a certain angle, the rotation of the rotating shaft 20 is stopped. During the sliding process of sliding member 1 28 , sliding member 2 30 slides along side guide surface 1 and then separates from side guide surface 1. At this time, sliding member 2 30 is slidably connected to the plane on sliding member 1 28 , sliding member 2 30 no longer squeezes sliding member 3 32 , and the side push frame 33 stops rotating.

At this time, the sliding key 1 43 is in a separated state from the locking groove 1 40, the sliding key 2 44 is separated from the locking groove 2 41, the sliding key 3 45 is snapped into the locking groove 2 41, and the sliding key 46 is snapped into the locking groove 3 42; the sliding key 2 44, the sliding key 3 45 and the locking groove 2 41 are all in a separated state; the sliding key 46 and the locking groove 3 42 are in a separated state; the sliding key 2 44 and the sliding key 3 45 are staggered along the circumference of the rotating shaft 20; at this time, the rotating shaft 20 is rotated in the opposite direction, and the rotating shaft 20 drives the transmission sprocket one 26 and the transmission sprocket two 36 to rotate synchronously; the width of the locking groove two 41 is greater than the width of the sliding key two 44 and the sliding key three 45, and the sliding key four 46 is adapted to the size of the locking groove three 42. When the rotating shaft 20 rotates in the opposite direction, the transmission sprocket two 36 rotates first with the rotating shaft 20, and the transmission sprocket one 26 rotates slightly later than the transmission sprocket two 36; the transmission component two 38 is preferably a transmission chain two, a transmission sprocket four and a transmission shaft three commonly used in the prior art and connected in sequence, the transmission shaft three is rotatably arranged on the bracket 8, the transmission sprocket four is arranged on the transmission shaft three, and the transmission chain two is set on the transmission sprocket two 36 and the transmission sprocket four; the eccentric wheel 37 is arranged on the transmission shaft three.

[0038] When the transmission sprocket 2 36 rotates with the rotating shaft 20, the eccentric wheel 37 is driven to rotate with the help of the power transmission of the transmission component 2 38. At this time, the positioning block is the first side of the sliding member 28, and the positioning block is exactly aligned with the groove M; when the eccentric wheel 37 rotates, it will squeeze the unlocking member 35 to slide in the direction close to the sliding member 28. With the squeezing of the eccentric wheel 37, the positioning block slides along the groove M and passes through the groove M. As the unlocking member 35 continues to slide, the unlocking member 35 will squeeze the sliding member 28 to slide in the direction away from the moving member 2; as the sliding member 28 gradually moves away from the sliding member 2 30, under the action of the side push frame 33's own gravity, the side push frame 33 squeezes the sliding member 32 to slide downward, and the sliding member 32 squeezes the sliding member 2 30 through the side guide surface 2 31 to slide in the direction close to the sliding member 28. Finally, the side push frame 33 and returns to the initial position. At this time, when the elastic member 39 is stretched to the longest, the highest point of the side push wheel is lower than the highest point of the roller.

[0039] When the unlocking member 35 squeezes the sliding member 1 28 away from the sliding member 2 30, the unlocking member 35 extends with the elastic member 39. The elastic member 39 is preferably a spring in the prior art. The elastic member 39 extends and accumulates elastic force. The transmission sprocket 1 26 starts to slide later than the transmission sprocket 2 36. The transmission sprocket 1 26 drives the side block 25 to slide in the opposite direction along the slide rail 24 through the transmission assembly 1 27. When the side block 25 slides in the opposite direction, it drives the sliding member 1 28 to slide on the unlocking member 35 along the slide groove 34, and the positioning block gradually moves. Away from slot M and close to slot N, when the side stopper 25 returns to its initial state, the positioning block is aligned with slot N. At this time, the elastic member three 39 releases the stored elastic force, and the positioning block slides along the slot N and passes through the slot N until the positioning block moves from the first side of the sliding member 28 to the second side; as the transmission sprocket 26 continues to rotate, the positioning block gradually approaches slot M and is aligned with slot M. With the help of the force provided by the elastic member three 39, the positioning block is located on the first side of the sliding member 28, waiting for the next test sample to complete the salt spray test.

[0040] Then, the rotating shaft 20 is pulled to slide away from the bracket 8, and the sliding distance is B+C, so that the rotating shaft 20 returns to the initial state, and the lateral displacement of the tray 7 is completed with the help of the linkage unit to realize the cyclic operation.
