Description

Technical Field

[0001] This disclosure relates to the field of sponge testing instrument technology, and in particular to a limiting device for a sponge testing instrument. Background Technology

[0002] Sponge testing instruments are specialized devices used to test the properties of sponge materials. They play a crucial role in production and quality control, helping manufacturers ensure product consistency and reliability through sponge testing. However, existing sponge testing instruments lack positioning limits for the sponge, requiring manual holding to prevent it from shaking. When performing mechanical tests such as compressive strength tests, this may cause the sponge sample to move or pop out under pressure, posing a safety risk to the operator. Furthermore, the position and orientation of the sponge may vary each time the test is conducted, affecting the repeatability and consistency of the test results. Utility Model Content

[0006] The hardness testing assembly includes a first push rod component, a support seat, and a pressure plate. The first push rod component is disposed inside the housing, and the piston end of the first push rod component passes through the housing and is connected to the support seat. The support seat is connected to the pressure plate through a connecting rod.

[0007] The limiting assembly includes a second push rod component, a pressure plate seat, and a limiting plate. Two sets of the second push rod components are provided and symmetrically distributed on both sides of the bracket. The pressure plate seat is located inside the bracket and is connected to the piston end of the second push rod component. Through the cooperation of the second push rod components, the two sets of pressure plate seats can be brought closer to or further away from each other.

[0008] The pressure plate base has several through slots, and several limiting plates are provided and moved in the through slots. By moving the limiting plates in the through slots, the limiting plates in the same position move closer or further apart.

[0010] In one embodiment, the pressure plate has an annular opening, and a rotating closing component is provided on the side of the pressure plate facing the machine base;

[0011] The rotary closing component includes a mounting shaft and a baffle. The mounting shaft is located on one side of the annular opening, and the baffle has an extension with a through hole. The extension is rotatably mounted on the mounting shaft through the through hole, so that the baffle has a degree of rotational freedom about the mounting shaft, allowing the baffle to cover or move away from the annular opening.

[0012] A retaining ring is provided at the bottom of the mounting shaft, and the extension is located between the pressure plate and the retaining ring.

[0013] In one embodiment, a support is provided on the pressure plate seat, and a slide groove is provided inside the support. One end of the slide groove extends to the outside of the support. A piercing assembly is movably provided on the slide groove. The piercing assembly includes a slide block, a support plate, a support rod, and a clamping plate. The slide block is movably provided in the slide groove, and the support plate is vertically provided on the slide block and located above the machine.

[0014] The support plate has an opening, and the support rod is movable and set in the opening and connected to the clamping plate. The clamping plate moves closer to or away from the support plate by moving the support rod.

[0015] The pallet has a pointed end on the side facing the machine.

[0016] In one embodiment, the outer periphery of the support rod is provided with an external thread, and the inner wall of the opening is provided with an internal thread that matches the external thread, and the support rod is threadedly connected to the opening.

[0017] A bearing is installed at the connection between the support rod and the clamping plate.

[0018] In one embodiment, the limiting plate has a receiving groove, and an extension plate is movably disposed within the receiving groove, with a portion of the extension plate movably disposed within the receiving groove.

[0019] In one embodiment, a protrusion is provided at the end of the extension plate away from the limiting plate, and the protrusion has a magnetic layer.

[0020] The magnetic poles of the magnetic layers between the two sets of limiting plates are opposite, so that the two sets of limiting plates can be magnetically connected when they come into contact.

[0021] In one embodiment, several tips are provided and evenly distributed on the card plate.

[0022] The advantages or beneficial effects of the above technical solutions include at least the following:

[0023] This invention discloses a limiting device for a sponge tester. The sponge to be tested is placed on the material tray of the machine. The second push rod component in the limiting assembly controls the movement of the pressure plate seat, causing it to abut against the side of the sponge. Since there are two sets of the second push rod component, both sets of pressure plates can simultaneously abut against both sides of the sponge and constrain it. Furthermore, since the pressure plate seat has several through slots, according to the size of the sponge, limiting plates are passed through the through slots and abut against the end face of the sponge. The cooperation of several limiting plates can limit both ends of the sponge. The receiving area formed by the pressure plate seat and the limiting plates restricts the movement of the sponge. When the pressure plate in the hardness testing assembly abuts against the sponge from the top with the cooperation of the first push rod component, the sponge cannot wobble because its perimeter is fixed by the pressure plate seat and the limiting plates. This solves the problem that traditional sponge testers lack sponge positioning, requiring manual positioning and posing safety hazards during testing. Attached Figure Description

[0040] Reference Figures 1-5A limiting device for a sponge tester includes a machine base 1, a support 2, a hardness testing component 3, and a limiting component 4. The support 2 is mounted on the machine base 1, which has a material tray 11 for placing the sponge to be processed. The support 2 is equipped with a housing. The hardness testing component 3 is used to test the sponge, and the limiting component 4 is used to limit the position of the sponge when it is placed.

[0041] The hardness testing component 3 includes a first push rod component 31, a support seat 32, and a pressure plate 33. The first push rod component 31 is disposed in the housing. The piston end of the first push rod component 31 passes through the housing and is connected to the support seat 32. The support seat 32 is connected to the pressure plate 33 through a connecting rod. Through the cooperation of the first push rod component 31 and the support seat 32, the pressure plate 33 can be moved closer to or further away from the sponge on the material tray 11.

[0042] The limiting assembly 4 includes a second push rod component 41, a pressure plate seat 42, and a limiting plate 43. The second push rod component 41 is provided in two sets and symmetrically distributed on both sides of the bracket 2. The pressure plate seat 42 is located inside the bracket 2 and is connected to the piston end of the second push rod component 41. Through the cooperation of the second push rod component 41, the two sets of pressure plate seats 42 can be brought closer to or further away from each other.

[0043] The pressure plate base 42 has several through slots 421 distributed on it. Several limiting plates 43 are provided and are movably disposed in the through slots 421. By moving the limiting plates 43 in the through slots 421, the limiting plates 43 in the same position can move closer or further apart. The setting of several through slots 421 can make the limiting plates 43 change position according to the size of the sponge.

[0044] The pressure plate seat 42 and the limiting plate 43 cooperate to form a receiving area for placing the sponge. The pressure plate seat 42 and the limiting plate 43 are located on the four sides of the sponge and limit its position.

[0045] Based on the above structure, the sponge to be tested is placed on the material tray 11, with the sponge positioned below the pressure plate 33. Then, the second push rod components 41 located on both sides of the bracket 2 control the movement of the pressure plate seats 42, causing the two sets of pressure plate seats 42 to abut against the sides of the sponge. Then, based on the sponge's width, the limiting plate 43 passes through the nearest set of through grooves 421, allowing the limiting plate 43 to abut against the end face of the sponge. Since the through grooves 421 are equipped with several grooves that enable the limiting plate 43 to abut against the sponge... The two ends abut against each other, so that the pressure plate seat 42 and the limiting plate 43 are in contact with the outer periphery of the sponge, thereby limiting the sponge. The pressure plate seat 42 is controlled by the second push rod component 41 so that the pressure plate seat 42 is always in close contact with the side of the sponge. Compared with the traditional method of manually positioning and holding the sponge, the cooperation between the pressure plate seat 42 and the limiting plate 43 in the limiting component 4 can solve the problem of safety hazards and difficulty in repeating the test consistency caused by the lack of positioning of the sponge during the test.

[0046] The first push rod component 31 and the second push rod component 41 mentioned above are both pneumatic push rods in the prior art.

[0047] In one embodiment, reference is made to Figures 1-3 The pressure plate 33 has an annular opening 331. A rotating closing component 34 is provided on the side of the pressure plate 33 facing the machine base 1. The rotating closing component 34 includes a mounting shaft 341 and a baffle 342. The mounting shaft 341 is located on one side of the annular opening 331. The baffle 342 has an extension 3421 with a through hole 111 and is rotatably mounted on the mounting shaft 341 through the through hole 111, giving the baffle 342 a degree of rotational freedom about the mounting shaft 341. This allows the baffle 342 to cover or move away from the annular opening 331. To further improve the detection effect of the sponge tester, an annular opening is provided on the pressure plate 33. 331. A ball used to test the elasticity of a sponge can fall onto the sponge from the annular opening 331. In order to ensure that different types of balls can fall from the same height, the extension 3421 in the baffle 342 allows the baffle 342 to rotate on the mounting shaft 341. When it rotates to a certain angle, the baffle 342 can cover the annular opening 331, so that the ball placed on the annular opening 331 will be blocked by the baffle 342. As the baffle 342 rotates, the annular opening 331 will be exposed again, and the ball will fall onto the sponge from the annular opening 331, thus completing the elasticity test of the sponge.

[0048] A retaining ring 3411 is provided at the bottom of the mounting shaft 341, and an extension 3421 is located between the pressure plate 33 and the retaining ring 3411. The retaining ring 3411 is provided to prevent the extension 3421 from falling off the mounting shaft 341.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 A support 422 is provided on the pressure plate seat 42, and a slide groove 4221 is provided inside the support 422. One end of the slide groove 4221 extends to the outside of the support 422. A puncture assembly 5 is movably arranged on the slide groove 4221. The puncture assembly 5 is used to fix the sponge from one end and to detect the tensile tear test of the sponge. The puncture assembly 5 includes a slide 51, a support plate 52, a support rod 53 and a clamping plate 54. The slide 51 is movably arranged in the slide groove 4221, and the support plate 52 is vertically arranged on the slide 51 and located above the machine base 1.

[0050] The support plate 52 has an opening 521. The support rod 53 is movably disposed within the opening 521 and connected to the clamping plate 54. The movement of the support rod 53 causes the clamping plate 54 to move closer to or further away from the support plate 52. The clamping plate 54 has several pointed parts 541 on the side facing the machine base 1, which are evenly distributed on the clamping plate 54. When the sponge is placed on the material tray 11, the slide block 51 moves to the position of the sponge with the cooperation of the slide groove 4221, so that the support plate 52 is positioned above the sponge, and is carried by the support rod 53. The moving plate 54 moves, causing the tip 541 to embed into the sponge, and the piercing component 5 clamps the sponge. Since the slide 51 is moved and set in the slide groove 4221 of the support 422, when the second push rod component 41 drives the pressure plate seat 42 to move, the piercing component 5 will move synchronously. When the piercing components 5 on the two sets of pressure plate seats 42 are evenly fixed to the sponge, the two sets of pressure plate seats 42 move away from each other and exert a stretching effect on the sponge, thereby enabling the tensile properties of the sponge to be tested.

[0051] The support rod 53 has an external thread 531 on its outer periphery and a handwheel on its top. The inner wall of the opening 521 has an internal thread 5211 that matches the external thread 531. The support rod 53 is threaded into the opening 521. A bearing is provided at the connection between the support rod 53 and the clamping plate 54. By rotating the handwheel, the support rod 53 can be moved in the direction of rotation, causing the clamping plate 54 to gradually approach the material tray 11. The bearing ensures that the clamping plate 54 does not rotate synchronously when the support rod 53 rotates. The threaded connection also prevents the clamping plate 54 from shaking when the sponge is stretched, thus improving the stability during testing.

[0052] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5The limiting plate 43 has a receiving groove 431, and an extension plate 432 is movably disposed in the receiving groove 431. Part of the extension plate 432 is movably disposed in the receiving groove 431. Since the length of the limiting plate 43 itself is fixed, by moving the extension plate 432 in the limiting plate 43, the extension plate 432 can fit with a larger sponge, thereby further improving the limiting range of the limiting plate 43.

[0053] The extension plate 432 has a protrusion 4321 at the end away from the limiting plate 43. The protrusion 4321 has a magnetic layer 4322. The magnetic poles of the magnetic layer 4322 between the two sets of limiting plates 43 are opposite, so that the two sets of limiting plates 43 can be magnetically connected when they come into contact. The two sets of limiting plates 43 can be connected with the extension plate 432 through the magnetic connection, thereby achieving the sealing of the outer periphery of the sponge.

[0054] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The material tray 11 has several evenly distributed through holes 111. The through holes 111 are connected to the interior of the machine base 1. The through holes 111 can increase the air permeability of the tray. For sponge samples that need to be tested for air permeability, this helps air circulation, thereby making the air permeability performance of the sponge more accurate.
