Description

Technical Field

[0001] This utility model relates to the field of PVA mop head production technology, specifically to a PVA mop head water absorption testing device. Background Technology

[0002] The biggest feature of the PVA mop is that while retaining the self-cleaning function of a wringer mop, the working head is made of polyvinyl alcohol (PVA) PVA. PVA has strong water absorption, ensuring the working head is easy to clean. The most important and crucial component of the PVA mop is the mop head. This head is highly absorbent, requiring no effort when mopping; a gentle swipe is all it takes for dust and hair to adhere to the head. Simply immerse the mop head in water or rinse it briefly under running water to clean the mop. Then, a gentle pull and release of the pull ring two or three times will remove the dirt from the head. The absorbency of the PVA mop head directly affects the overall performance of the mop; therefore, it is often tested after production.

[0003] In existing water absorption testing technologies for PVA mop heads, a water absorption testing structure for PVA mop head production disclosed in Chinese Patent CN222087536U is included. This structure comprises a test water tank, an L-shaped mounting bracket fixedly installed at the top of the tank, a pair of test clamps movably arranged inside the tank, a test plate movably arranged below the L-shaped mounting bracket, several electromagnetic weighing devices fixedly installed at the bottom of the test plate, a fixed mounting bracket fixedly installed at the bottom of the electromagnetic weighing devices, and an elastic drawstring fixedly installed at the bottom of the fixed mounting bracket. The mop head to be tested is placed inside the elastic drawstring. By setting up movable components, the test clamps are brought closer together, thereby squeezing out the water on the mop head. This also avoids the need for electronic components inside the test water tank, increasing the device's effectiveness. A drive assembly is provided, with a drive motor rotating a drive threaded rod, causing the test plate to move up and down. A limiting block slides within a through groove, preventing the test plate from rotating.

[0004] The existing patented technology tests the water absorption of a mop head by absorbing water, draining the stored water, weighing the mop head, squeezing out the water, and weighing it again, using the weight difference between the two tests. This testing method has the following technical defects: First, in actual use, the mop head is generally squeezed and wiped to absorb water when used on the ground, and direct soaking cannot guarantee that the mop head will absorb water completely. Second, the weight difference test after soaking and weighing, and after squeezing, cannot guarantee that the water will be completely drained, thus greatly affecting the test results. Therefore, we propose a PVA mop head water absorption testing device to solve this defect of the existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water absorption testing device for plywood mop heads.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water absorption test device for a sponge mop head, including a base, a transparent measuring cylinder detachably provided at the center of the upper end of the base, the transparent measuring cylinder storing cleaning water, a support frame provided on the outside of the base, an electric push rod provided at the upper end of the support frame, a mop head fixing ring provided at the push rod of the electric push rod, the mop head fixing ring being located above the opening of the transparent measuring cylinder and concentrically arranged, and a locking component for fixing the mop head being provided on the mop head fixing ring;

[0007] An electric push rod is provided on the outside of the transparent measuring cylinder. The push rod of the electric push rod passes through the inside of the transparent measuring cylinder, and a clamp is provided at the push rod.

[0008] Using the above technical solution, the end of the mop head is placed inside the mop head fixing ring and fixed with the locking component. Then, the volume of water stored in the transparent measuring cylinder is recorded. Electric push rod one pushes the fixed mop head into the water stored in the transparent measuring cylinder. Electric push rod two pushes the clamping plate back and forth, so that the clamping plate repeatedly squeezes the mop head to ensure that the mop head completely absorbs water. After the water is absorbed, electric push rod one moves the fixed mop head to the top of the transparent measuring cylinder until the water on the surface of the mop head drips completely into the transparent measuring cylinder. At this time, the volume of water stored is recorded again. Then, the difference between the two volume scales is calculated to obtain the water absorption of the mop head, ensuring the accuracy of the water absorption test results of the sponge mop head.

[0009] As a preferred embodiment of this utility model, the bottom of the base is provided with a plurality of support legs, and the support legs are provided with a plurality of fixing holes.

[0010] By using the above technical solution, the support leg can be fixed to the mounting carrier by passing the screw through the fixing hole, thus installing and fixing the entire device.

[0011] As a preferred embodiment of this utility model, a sealing ring is provided at the push rod of the transparent measuring cylinder and the electric push rod II.

[0012] By adopting the above technical solution, the sealing ring ensures a sealing effect and prevents water leakage when the push rod moves.

[0013] As a preferred embodiment of this utility model, the locking assembly includes a nut disposed outside the mop head fixing ring, and a threaded locking rod is internally threaded onto the nut, the threaded locking rod passing through into the mop head fixing ring.

[0014] Using the above technical solution, after one end of the mop head is located inside the mop head retaining ring, the threaded locking rod inside the nut is screwed in to fix the mop head inside the mop head retaining ring.

[0015] As a preferred technical solution of this utility model, the support frame is provided with loading frames on both the front and rear sides, and an electric push rod three is provided on the outer side of the loading frame. A roller seat is provided at the push rod of the electric push rod three, and a compression roller rotates inside the roller seat.

[0016] Using the above technical solution, after the water absorption test is completed, as the mop head is moved up by the electric push rod one, the electric push rod three on the loading frame pushes the squeezing roller on the roller seat to squeeze the mop head. With the rotation of the squeezing roller, the tested mop head can be squeezed and dehydrated.

[0017] As a preferred technical solution of this utility model, the upper end of the base is provided with a controller, and electric push rod one, electric push rod two and electric push rod three are all electrically connected to the controller.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. This PVA mop head water absorption test device works by placing the end of the mop head into the mop head fixing ring and securing it with the locking component. The volume of water stored in the transparent measuring cylinder is then recorded. An electric push rod pushes the fixed mop head into the water stored in the transparent measuring cylinder, while an electric push rod 2 moves the clamping plate back and forth, repeatedly squeezing the mop head to ensure complete water absorption. After absorption, the electric push rod moves the fixed mop head above the transparent measuring cylinder until all the water on the mop head surface drips into the cylinder. The volume of water stored is recorded again at this point. The difference between the two volume readings is then calculated to obtain the water absorption amount of the mop head, ensuring the accuracy of the PVA mop head water absorption test results.

[0020] 2. After the water absorption test is completed, the electric push rod 1 drives the mop head to move up, and the electric push rod 3 on the loading frame pushes the squeezing roller on the roller seat to squeeze the mop head. With the rotation of the squeezing roller, the tested mop head can be squeezed and dehydrated. Attached Figure Description

When installing the mop head, one end of the mop head is inserted into the mop head retaining ring 5, and then the threaded locking rod 7 inside the nut 6 is rotated to screw in the thread, gradually pressing the mop head and thus firmly fixing the mop head in the mop head retaining ring 5.

[0035] An electric actuator 8 is fixed to the outside of the transparent measuring cylinder 2. The actuator 8 extends into the interior of the transparent measuring cylinder 2, and a clamping plate 9 is fixed to the actuator. The electric actuator 8 also uses a motor-driven lead screw structure, which can precisely control the movement of the clamping plate 9. To ensure a sealing effect and prevent water leakage when the actuator moves, a sealing ring is fixedly fitted at the actuator of the transparent measuring cylinder 2 and the electric actuator 8. The sealing ring is made of rubber and has good elasticity and sealing performance.

[0036] The clamp 9 is fixed to the end of the push rod of the electric push rod 2 8 and is used to repeatedly squeeze the mop head immersed in water.

[0042] Beneficial effects

[0043] Accurate Testing: This device, after fixing the end of the mop head inside the mop head fixing ring 5, first records the volume of water stored in the transparent measuring cylinder 2. Then, the electric push rod 4 pushes the fixed mop head into the water stored in the transparent measuring cylinder 2. Next, the electric push rod 8 pushes the clamping plate 9 back and forth, realizing the repeated squeezing of the mop head by the clamping plate 9, simulating the squeezing and wiping water absorption method of the mop head in actual use, ensuring that the mop head completely absorbs water. After the water absorption is completed, the electric push rod 4 moves the fixed mop head to the top of the transparent measuring cylinder 2 until the water on the surface of the mop head completely drips into the transparent measuring cylinder 2. The volume of water stored is recorded again. The difference between the two volume scales can be calculated to obtain the amount of water absorbed by the mop head, which greatly improves the accuracy of the test results.

[0044] Convenient dehydration: After the water absorption test is completed, as the electric push rod 4 moves the mop head up, the electric push rod 3 12 on the loading frame 11 pushes the squeezing roller 14 on the roller seat 13 to squeeze the mop head. With the rotation of the squeezing roller 14, the tested mop head can be effectively squeezed and dehydrated, which is convenient for subsequent processing and retesting of the mop head.

[0045] Automation control: The controller 10 centrally controls each electric push rod, realizing the automation of the testing process, reducing human operation errors, and improving testing efficiency and reliability. At the same time, the operation panel design of the controller 10 allows operators to easily set test parameters and monitor the testing process.

[0046] Usage steps,

[0047] Preparation: Pour an appropriate amount of clean water into the transparent graduated cylinder 2 and record the initial volume of the water at this time.

[0048] Fixing the mop head: Place the end of the PVA mop head to be tested into the mop head fixing ring 5, and rotate the threaded locking rod 7 inside the nut 6 to screw in the thread, thus firmly fixing the mop head into the mop head fixing ring 5.

[0049] Water absorption test: The controller 10 starts the electric push rod 4, which extends downward and pushes the fixed mop head into the water stored in the transparent measuring cylinder 2. Then the electric push rod 8 is started, which drives the clamping plate 9 to move back and forth, repeatedly squeezing the mop head immersed in water. The number of squeezing times can be set on the controller 10 according to the actual test requirements, for example, 5-10 times. During the squeezing process, the squeezing and wiping water absorption method of the mop head in actual use is simulated to ensure that the mop head completely absorbs water.

[0050] Drainage measurement: After water absorption is completed, the controller 10 controls the push rod of the electric push rod 4 to retract upward, which drives the fixed mop head to move above the transparent measuring cylinder 2, so that the water on the surface of the mop head drips completely into the transparent measuring cylinder 2. When the water stops dripping, the volume scale of the water stored in the transparent measuring cylinder 2 is recorded again.

[0051] Calculate water absorption: The water absorption of the mop head can be calculated based on the difference in volume between the two recorded measurements.

[0052] Dehydration treatment: After the water absorption test is completed, as the electric push rod 4 moves the mop head upward, the controller 10 starts the electric push rod 3 12, which pushes the squeezing roller 14 on the roller seat 13 to squeeze the mop head. With the rotation of the squeezing roller 14, the tested mop head is squeezed and dehydrated.

[0053] In summary, this PVA mop head water absorption testing device has a reasonable structure, is easy to operate, and provides accurate testing. It can effectively solve the problems existing in the prior art and provide a reliable testing method for the production quality inspection of PVA mop heads.
