Description

Technical Field

[0001] The present invention belongs to the technical field of testing equipment, and specifically relates to an impact resistance testing equipment for epoxy floor coatings. Background Art

[0002] As a high-performance floor material, epoxy floor coatings are widely used in industrial plants, parking lots and other places due to their excellent wear resistance and chemical corrosion resistance. Among the many types of epoxy floor coatings, epoxy floor rolls provide a more convenient and efficient solution for floor decoration and protection with their unique prefabricated and rollable characteristics. However, during the actual application process of epoxy floor rolls, they need to withstand external forces such as vehicles, heavy objects, and machinery. Therefore, during the production and processing of epoxy floor rolls, it is necessary to test the impact resistance of epoxy floor rolls.

[0003] The patent with the publication number CN118641385B discloses an EVA polyethylene composite roll floor strength testing equipment, including a support table. On the upper surface of the support table, two vertical plates are symmetrically and fixedly installed. Between the two vertical plates, a guide rod is fixedly installed. On the upper surface of the guide rod, a guide rail is slidably installed. Inside the inner wall of the guide rail, a counterweight block is slidably installed. At the bottom end of the counterweight block, an impact ball head is fixedly installed. This patent uses a lifting mechanism to lift and drop the counterweight block, so that the impact ball head installed at the bottom of the counterweight block impacts the surface of the EVA polyethylene composite roll floor on the support table, so as to subsequently use an industrial camera to take pictures and compare and detect the floor surface, and thus determine the anti-shattering ability of the floor according to the integrity of the floor surface, and determine whether the strength of the EVA polyethylene composite roll floor meets the standard. There is no need to manually hammer the EVA polyethylene composite roll floor to test its strength, which can effectively reduce the labor intensity of quality inspection personnel.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: When performing an impact resistance test on a roll, the roll to be tested is laid flat on the support table, and the roll is slowly wound up by a winding device. During winding, the counterweight block freely falls downward under its own weight, and the impact ball head impacts the surface of the roll. Subsequently, an industrial camera is used to take pictures and compare and detect the surface of the roll, and its impact resistance is determined based on the integrity of the roll surface.

[0005] To facilitate the industrial camera to clearly and accurately capture the deformation size of the roll surface, a coating roller is dipped in the paint on a sponge and the paint is printed on the surface of the roll after being impacted. Since pits and other deformations will occur on the roll after being impacted, the paint on the coating roller will not be coated into the pits, so that the color in the pits is significantly different from the color of the roll surface, which is convenient for the industrial camera to take pictures.

[0006] However, in some cases, to save time and cost in the testing work, only some random areas on the surface of the coil are subjected to the impact resistance test to represent the overall performance. However, since the coating roller is in continuous contact with the surface of the coil, it will cause the non-tested areas of the coil to be coated with pigments. If the coil needs to be tested again for impact resistance and other tests later, the pigments will interfere with the test results. Even if the coating roller is intermittently in contact with the surface of the coil so that the pigments are only coated on the tested area, after the coil is wound up, the pigments in the tested area will still contaminate the non-tested areas of the coil, which also affects the subsequent re-testing work of the coil.

[0018] The beneficial effects of the present invention are as follows: 1. For an epoxy floor impact resistance testing device of the present invention, by using the shooting auxiliary component, after the coil passes through an impact resistance test once, the dyeing roller can coat the pigment on the test area of the coil, so that the color in the pit is significantly different from the color on the surface of the coil. When the test area of the coil moves below the industrial camera, the industrial camera takes a picture of it, and then the deformation size of the surface of the coil can be photographed more clearly and accurately, so as to judge the impact resistance performance of the coil subsequently.

[0019] 2. For an epoxy floor impact resistance testing device of the present invention, by using the anti-staining component, after the test area of the coil is coated with the pigment, the tape can be evenly attached to its test area to cover the test area. Thus, after the coil is wound up, the pigment coated on the test area of its surface will not stain the non-test area of the coil, avoiding the situation that the pigment interferes with the test result when the coil is tested again subsequently.

[0020] 3. An epoxy floor impact resistance testing device according to the present invention utilizes a pit-adaptive reinforcement component. When one end of the tape is pressed tightly against the surface of the coil and the second groove plate starts to move horizontally, multiple rollers come into contact with the surface of the tape and roll simultaneously. Because it can adapt to the uneven changes in the testing area, no matter passing through uneven areas, it can press the tape tightly against the surface of the coil. At the same time, the multiple rollers generate horizontal reciprocating movements and perform compound movements in multiple directions, which can avoid the situation of pressing dead corners due to gaps between adjacent rollers, further ensuring the pressing effect until the rollers move to the end of the tape attached to the testing area. Thus, it avoids the situation that after the tape is attached to the surface of the coil, it is easy to fall off due to some areas not being in contact with the surface of the coil, and the situation that the pigment flows out from the gap between the tape and the coil and contaminates the rest of the surface of the coil.

[0033] Specifically, in the prior art, when performing an impact resistance test on a coil, the coil to be tested is laid flat on a support table, and the coil is slowly wound by a winding device. During winding, the counterweight freely falls downward under its own weight, and the surface of the coil is impacted by an impact ball head. Subsequently, an industrial camera 61 is used to take pictures of the surface of the coil for comparative detection, and the impact resistance of the coil is determined based on the integrity of the surface of the coil.

[0034] To facilitate the industrial camera 61 to clearly and accurately photograph the deformation size of the surface of the coil, the surface of the coating roller 27 is dipped in the paint on the sponge, and the paint is printed on the surface of the coil after being impacted. Since the coil will generate deformations such as pits after being impacted, the paint on the coating roller 27 will not be coated into the pits, so that the color in the pits is significantly different from the color of the surface of the coil, which is convenient for the industrial camera 61 to take pictures.

[0035] However, in some cases, to save the time and cost of the testing work, only some random areas on the surface of the coil are subjected to the impact resistance test to represent the overall performance. However, since the coating roller 27 is in continuous contact with the surface of the coil, the non-tested areas of the coil will also be coated with pigments. If the coil needs to be tested again for impact resistance or other tests later, the pigments will interfere with the test results. Even if the coating roller 27 is intermittently in contact with the surface of the coil so that the pigments are only coated on the tested areas, after the coil is wound up, the pigments on the tested areas will still stain the non-tested areas of the coil, which also affects the subsequent re-testing work of the coil.

[0036] Therefore, to solve the above problems, when in use in this embodiment, the epoxy floor coil to be tested is passed through the bottoms of the limiting rollers 8 on both sides and laid flat on the test bench 1, and the coil is pressed by the limiting rollers 8.

[0037] Then, the coil is wound up by the winding device. When the area of the coil that needs to be tested reaches below the impact block 11, the cylinder 15 drives the lifting block 16 to move horizontally, so that the lifting block 16 moves away from the bottom of the lifting rod 3. Then the lifting rod 3 loses support, and the impact block 11 drops downward under the action of gravity and impacts the surface of the coil. Then the cylinder 15 drives the lifting block 16 to move below the lifting rod 3. At the same time, the motor 12 drives the threaded rod 13 to rotate, so that the L-shaped plate 14 rises, and then the lifting block 16 pushes the lifting rod 3 to rise, so that the impact block 11 returns to its initial position for another impact. Next, the pump body 21 pumps out the pigments inside the pigment box 20, and the pigments flow into the inner cavity of the housing 25 through the long pipe 23 and the branch pipe 24 and impregnate the sponge roller 26. Then the motor 28 drives the coating roller 27 to rotate, and through the friction between the coating roller 27 and the sponge roller 26, the surface of the coating roller 27 is evenly stained with pigments.

[0038] When the tested area of the coil moves below the coating roller 27, the motor 17 drives the threaded rod 5 to rotate, so that the connecting plate 6 descends, and the coating roller 27 fits with the surface of the coil, and the pigments are coated on the surface of the coil. The coil continues to be wound up. And, with the cooperation of the sliding rod 18 and the spring 19, the coating roller 27 is always in close contact with the surface of the coil. Since the coil will have deformations such as pits after being impacted, the coatings on the coating roller 27 will not be coated into the pits, so that the color in the pits is significantly different from the color on the surface of the coil. When the tested area of the coil moves below the industrial camera 61, the industrial camera 61 takes a picture of it, and then the deformation size on the surface of the coil can be taken more clearly and accurately, so as to judge the impact resistance performance of the coil later.

[0039] Since one end of the tape on the surface of the tape roll 37 is in a hanging state, when the test area with the pigment coated on the surface of the coil moves below the mounting plate 10, the motors nine 53 on both sides drive the pressure rods 54 to rotate simultaneously. By contacting the glue-applying surface of the tape with the pressure rods 54, the end of the tape is pressed tightly on the surface of the suction cup 56. Subsequently, the electric push rod two 38 drives the support plate 41 to descend, and the motor six 36 drives the rotating column 58 to rotate to unwind the tape. When the end of the tape is about to contact the surface of the coil, the motor seven 42 drives the rotating tube 57 to rotate by ninety degrees to bend the end of the tape. At this time, the glue-applying surface of the bent part of the tape faces downward. Then, the air pump 40 is used to extract the air at the joint between the suction cup 56 and the tape, and the suction cup 56 is used to adsorb the tape. At the same time, the motor nine 53 drives the pressure rod 54 to rotate, causing the pressure rod 54 to separate from the glue-applying surface of the tape. Then, the electric push rod two 38 drives the support plate 41 to descend again, and the end of the tape can be pressed on the surface of the coil through the suction cup 56. Since the glue-applying surface of the tape is attached to the surface of the coil, at this time, the suction cup 56 can release the tape, and the suction cup 56 is attached to the non-glue-applying surface of the tape instead of adsorbing it. Then, the motor ten 63 drives the threaded rod five 62 to rotate, causing the groove plate two 7 to slide horizontally on the upper end surface of the test bench 1. At the same time, the tape roll 37 unwinds the tape, and the unwound tape will be laid flat on the surface of the coil under the limitation of the suction cup 56. When the tape is unwound to a certain length, the motor four 29 drives the threaded rod three 35 to rotate, causing the cross-moving rod 32 to slide on the mounting plate 10, so that the tape is located between the blade plate 34 and the cross-moving rod 32. Then, the electric push rod one 33 drives the blade plate 34 to move horizontally, and the blade plate 34 is used to cut the tape. Subsequently, the blade plate 34 resets. At this time, a piece of tape is attached to the test area of the coil. Then, the above operation is repeated again. By driving the threaded rod two 30 to rotate through the motor five 31, the attachment position of the tape is changed until the tape covers the test area with the pigment coated on the surface of the coil. Thus, after the coil is wound up, the pigment coated on the test area of its surface will not contaminate the non-test area of the coil, avoiding the situation that when the coil is tested again later, the pigment interferes with the test results due to the contamination of the non-test area of the coil with the pigment.

[0040] In this embodiment, as Figure 4 , Figure 8 , Figure 9 shown, a pit-adaptive reinforcement component is further provided on the support plate 41; The pit-adaptive reinforcement component includes a cylinder two 43 fixedly connected to one side of the upper end of the support plate 41. The piston end of the cylinder two 43 is fixedly connected with a groove plate three 47. A reciprocating plate 48 is slidably connected to the chute of the groove plate three 47. A plurality of sliding rods three 51 are horizontally and equidistantly distributed and slidably connected to one side of the reciprocating plate 48. The lower ends of the sliding rods three 51 are fixedly connected with a connecting block 50. A roller 49 is rotatably arranged on one side of the connecting block 50.

[0041] One end of the reciprocating plate 48 is threadedly connected to a reciprocating lead screw 46. Both ends of the reciprocating lead screw 46 are rotatably arranged on the third groove plate 47. One end of the third groove plate 47 is fixedly connected to an eighth motor 45. The output end of the eighth motor 45 is fixedly connected to one end of the reciprocating lead screw 46. One end of the third slide bar 51 is sleeved with a second spring 52. One end of the second spring 52 is fixedly connected to the reciprocating plate 48, and the other end is fixedly connected to the end of the third slide bar 51.

[0042] Specifically, in the above embodiment, although the tape is attached to the test area of the coil to prevent the pigment from staining the non-test area after the coil is wound, however, since there may be multiple pits and protrusions in the test area, after the tape is attached to the surface of the coil, there may be a situation where some areas of the tape are not in contact with the surface of the coil. This not only easily causes the tape to fall off, but also may cause the pigment to flow out from the gap between the tape and the coil, still staining the remaining positions on the surface of the coil. Therefore, to solve the above problems, when this embodiment is in use, when one end of the tape is pressed tightly on the surface of the coil and the second groove plate 7 starts to move horizontally, the second cylinder 43 drives the third groove plate 47 to descend, so that multiple rollers 49 are simultaneously in contact with the surface of the tape. And, with the cooperation of the third slide bar 51 and the second spring 52, the rollers 49 can adapt to the concave and convex changes of the test area. When the second groove plate 7 moves horizontally, the rollers 49 roll on the surface of the tape. Since the rollers 49 can adapt to the concave and convex changes of the test area, in the area passed by the rollers 49, regardless of the concavity or convexity, this part of the tape can be pressed tightly on the surface of the coil. At the same time, the eighth motor 45 drives the reciprocating lead screw 46 to rotate, causing the multiple rollers 49 to make a horizontal reciprocating movement. Then the rollers 49 perform a composite movement in multiple directions, which can avoid the situation of pressing dead corners due to the gap between two adjacent rollers 49, further ensuring the pressing effect until the rollers 49 move to the end of the tape attached to the test area. Thus, it is avoided that after the tape is attached to the surface of the coil, due to some areas of the tape not being in contact with the surface of the coil, the tape is easily detached, and it is also possible that the pigment flows out from the gap between the tape and the coil, still staining the remaining positions on the surface of the coil.

[0043] Working principle: Pass the epoxy floor coil to be tested through the bottom of the limit rollers 8 on both sides, lay it flat on the test bench 1, and the coil is pressed by the limit rollers 8. Then, the coil is wound by the winding device. When the area of the coil to be tested reaches below the impact block 11, the cylinder 15 drives the lifting block 16 to move horizontally, so that the lifting block 16 moves away from the bottom of the lifting rod 3, and then the lifting rod 3 loses support. The impact block 11 drops downward under the action of gravity and impacts the surface of the coil. Then, the cylinder 15 drives the lifting block 16 to move under the lifting rod 3. At the same time, the motor 12 drives the threaded rod 13 to rotate, so that the L-shaped plate 14 rises, and then the lifting block 16 pushes the lifting rod 3 to rise, so that the impact block 11 returns to its initial position for another impact. Next, the pump body 21 pumps out the pigment inside the pigment box 20, flows into the inner cavity of the housing 25 through the long pipe 23 and the branch pipe 24 and impregnates the sponge roller 26. Then, the motor 28 drives the coating roller 27 to rotate. Through the friction between the coating roller 27 and the sponge roller 26, the surface of the coating roller 27 is evenly stained with pigment. When the tested area of the coil moves below the coating roller 27, the motor 17 drives the threaded rod 5 to rotate, so that the connecting plate 6 descends, and the coating roller 27 fits with the surface of the coil, and the pigment is coated on the surface of the coil. The coil continues to be wound. And, with the cooperation of the sliding rod 18 and the spring 19, the coating roller 27 is always in close contact with the surface of the coil. Since the coil will generate deformations such as pits after being impacted, the paint on the coating roller 27 will not be coated into the pits, so that the color in the pits is significantly different from the color on the surface of the coil. When the tested area of the coil moves below the industrial camera 61, the industrial camera 61 takes a picture of it, and then the deformation size of the surface of the coil can be more clearly and accurately photographed to facilitate the subsequent judgment of the impact resistance of the coil. Since one end of the tape on the surface of the tape roll 37 is in a hanging state, when the tested area of the coil surface coated with pigment moves below the mounting plate 10, the motors 53 on both sides drive the pressure rods 54 to rotate at the same time. By contacting the pressure rods 54 with the glue-coated surface of the tape, the end of the tape is pressed tightly on the surface of the suction cup 56. Subsequently, the electric push rod 38 drives the support plate 41 to descend, and the motor 36 drives the rotating column 58 to rotate to unwind the tape. When the end of the tape is about to contact the surface of the coil, the motor 42 drives the rotating tube 57 to rotate 90 degrees to bend the end of the tape. At this time, the glue-coated surface of the bent part of the tape faces downward. Then, the air pump 40 is used to extract the air at the joint between the suction cup 56 and the tape, and the suction cup 56 is used to adsorb the tape. At the same time, the motor 53 drives the pressure rod 54 to rotate, so that the pressure rod 54 is separated from the glue-coated surface of the tape. Then, the electric push rod 38 drives the support plate 41 to descend again, and the end of the tape can be pressed on the surface of the coil through the suction cup 56. Since the glue-coated surface of the tape fits with the surface of the coil, at this time, the suction cup 56 can release the tape, and the suction cup 56 fits with the non-glue-coated surface of the tape instead of adsorbing it.Then, the motor ten 63 drives the rotation of the threaded rod five 62, causing the groove plate two 7 to slide horizontally on the upper end surface of the test bench 1. At the same time, the tape reel 37 unwinds the tape, and the unwound tape will be laid flat on the surface of the coil under the limitation of the suction cup 56. When the tape is unwound to a certain length, the motor four 29 drives the rotation of the threaded rod three 35, causing the transverse movement rod 32 to slide on the mounting plate 10, placing the tape between the blade plate 34 and the transverse movement rod 32. Then, the electric push rod one 33 drives the blade plate 34 to move horizontally, using the blade plate 34 to cut the tape. Subsequently, the blade plate 34 resets. At this time, a piece of tape is attached to the test area of the coil. Then, repeat the above operations again. By driving the rotation of the threaded rod two 30 with the motor five 31, the attachment position of the tape is changed until the tape covers the test area coated with pigment on the surface of the coil. As a result, after the coil is wound up, the pigment coated on the test area of its surface will not contaminate the non-test area of the coil, avoiding the situation where the pigment contaminates the non-test area of the coil and interfering with the test results when the coil is tested again later. When one end of the tape is pressed tightly on the surface of the coil and the groove plate two 7 starts to move horizontally, the cylinder two 43 drives the groove plate three 47 to descend, causing multiple rollers 49 to contact the surface of the tape simultaneously. Moreover, with the cooperation of the slide rod three 51 and the spring two 52, the rollers 49 can adapt to the uneven changes in the test area. When the groove plate two 7 moves horizontally, the rollers 49 roll on the surface of the tape. Since the rollers 49 can adapt to the uneven changes in the test area, in the area passed by the rollers 49, regardless of the unevenness, this part of the tape can be pressed tightly on the surface of the coil. At the same time, the motor eight 45 drives the reciprocating screw rod 46 to rotate, causing the multiple rollers 49 to perform horizontal reciprocating movements. Then, the rollers 49 perform compound movements in multiple directions, which can avoid the situation of pressing dead corners due to the gap between two adjacent rollers 49, further ensuring the pressing effect until the rollers 49 move to the end of the tape attached to the test area. Thus, after the tape is attached to the surface of the coil, it can be avoided that the tape is prone to falling off because some areas of the tape do not fit the surface of the coil, and it can also be avoided that the pigment flows out from the gap between the tape and the coil and still contaminates the remaining positions on the surface of the coil.
