Description

Technical Field

[0001] The utility model relates to the technical field of paint testing equipment, in particular to a film impact tester. Background Art

[0002] During the production process of paint, in order to test the quality of paint products, film impact tests are often required. That is, according to relevant standards, paint is applied on a test panel to form a film with a certain thickness, and then a falling heavy hammer is used to impact the film at a set point. The maximum height at which the film is not damaged is the impact resistance of the tested film.

[0003] For example, a film impact tester is disclosed in CN213022579U, which includes: a fixing plate provided with an installation cavity for placing a test panel; a guide rail vertically arranged at the upper end of the fixing plate, and the guide rail is provided with a sliding cavity vertically communicating with the installation cavity; an impact block slidably arranged in the sliding cavity, a handle extending out of the sliding cavity is arranged on the side wall of the impact block, a plurality of detachable impact heads are arranged at the lower end of the impact block, and the distribution positions of the impact heads correspond to the set impact points; an energy storage component arranged at the upper end of the installation cavity for pushing the impact block downward; a locking component slidably arranged at the upper part of the guide rail, the locking component can extend into the installation cavity or be withdrawn from the installation cavity under the action of an external force, and a plurality of turning pieces are arranged on the locking component within the moving stroke range of the impact block. The plurality of turning pieces are perpendicular to the inner wall of the sliding cavity. When the impact block slides upward to abut against the turning pieces and turn them upward to be embedded in the inner wall of the sliding cavity, the turning pieces rotate back to be perpendicular to the inner wall of the sliding cavity when not affected by an external force.

[0004] The above-mentioned film impact tester is used for conducting film impact tests. However, the size of the installation cavity on the above-mentioned test panel is determined, and it can only stably place a test panel with a film of a certain thickness. It cannot adjust the film thickness, and when placing the test panel into or removing it from the installation cavity, due to a just right fit, the friction force is relatively large and it is not easy to operate. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the purpose of the present utility model is to provide a film impact tester to solve the problems in the prior art that it is impossible to adjust the film thickness for film impact tests and it is not easy to place the test panel into or remove it from the installation cavity.

[0006] To achieve the above purpose, the present utility model adopts the following technical solution: a film impact tester, including a base assembly, and the base assembly includes:

[0007] a base, and the base has an installation cavity for placing a test panel;

[0008] Adjusting plate, which is distributed along its length direction in the installation cavity and is arranged to slide vertically in the installation cavity;

[0009] Adjusting part, which is arranged between the base and the adjusting plate and is used to control the relative position of the adjusting plate in the vertical direction in the installation cavity.

[0010] Technical principle:

[0011] By means of the adjusting part, the adjusting plate is moved downward in the installation cavity to increase the height of the installation cavity to be greater than the thickness of the test plate, then the test plate can be easily placed in the installation cavity on the adjusting plate. After that, by means of the adjusting part, the adjusting plate is moved upward in the installation cavity until the test plate is clamped between the top wall in the installation cavity and the adjusting plate. At this time, the film impact test can be carried out; after the film impact test is completed, by means of the adjusting part, the adjusting plate is moved downward in the installation cavity to make the test plate out of the clamped state, and then the test plate can be easily removed from the installation cavity.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By means of the adjusting part, the adjusting plate is moved in the vertical direction in the installation cavity, so that the distance between the top wall in the installation cavity and the adjusting plate can be increased or decreased, which is convenient for easily placing the test plate in the installation cavity for the film impact test or removing it from the installation cavity;

[0014] 2. Since the distance between the top wall in the installation cavity and the adjusting plate can be increased or decreased, test plates with different film thicknesses can be placed in the installation cavity for the film impact test, enriching the use. Description of the drawings

Specific embodiments

[0017] The following further details the utility model through specific embodiments:

[0018] Since the size of the installation cavity 4 on the test plate in the existing film impact tester is determined, only test plates with a certain film thickness can be stably placed, the film thickness cannot be adjusted, and the friction is large and it is not easy to operate during the process of placing the test plate in the installation cavity 4 or removing it from the installation cavity 4 because of just fitting. To solve this problem, asFigure 1 As shown in the figure, an embodiment of the present utility model provides a paint film impact tester, which includes a base assembly. The base assembly includes a base 1, an adjusting plate 2, and an adjusting part 3. Among them, the base 1 has an installation cavity 4 for placing a test plate. The adjusting plate 2 is distributed along the length direction in the installation cavity 4 and is arranged to slide vertically in the installation cavity 4. The adjusting part 3 is arranged between the base 1 and the adjusting plate 2 and is used to control the relative position of the adjusting plate 2 in the installation cavity 4 along the vertical direction.

[0019] During use: By means of the adjusting part 3, the adjusting plate 2 is moved downward in the installation cavity 4 to increase the height of the installation cavity 4 to be greater than the thickness of the test plate. Then, the test plate can be easily placed in the installation cavity 4 on the adjusting plate 2. Subsequently, by means of the adjusting part 3, the adjusting plate 2 is moved upward in the installation cavity 4 until the test plate is clamped between the inner top wall of the installation cavity 4 and the adjusting plate 2. At this time, the paint film impact test can be carried out. After the paint film impact test is completed, by means of the adjusting part 3, the adjusting plate 2 is moved downward in the installation cavity 4 to release the clamping state of the test plate, and then the test plate can be easily removed from the installation cavity 4.

[0020] By means of the adjusting part 3, the adjusting plate 2 is moved vertically in the installation cavity 4, so that the distance between the inner top wall of the installation cavity 4 and the adjusting plate 2 can be increased or decreased, which is convenient for easily placing the test plate in the installation cavity 4 for the paint film impact test or removing it from the installation cavity 4. Since the distance between the inner top wall of the installation cavity 4 and the adjusting plate 2 can be increased or decreased, test plates with paint films of different thicknesses can be placed in the installation cavity 4 for the paint film impact test, enriching the use.

[0021] The above-mentioned installation cavity 4 is a through hole opened in the base 1 along the horizontal direction.

[0022] To better understand this solution, the following will further optimize the structure.

[0023] As Figure 1 shown, according to another embodiment of the present utility model, in the paint film impact tester, the adjusting part 3 includes a jacking structure and an adjusting structure. There are multiple jacking structures, and all of them are connected to the bottom of the adjusting plate 2. The multiple jacking structures are distributed along the length direction of the adjusting plate 2. Each jacking structure is provided with a first installation channel opened in the base 1 and located below the adjusting plate 2. The adjusting structure is connected to each jacking structure and is used to adjust the relative length of the jacking structure in the corresponding first installation channel along the vertical direction.

[0024] Herein:

[0025] The adjustment structure is used to synchronously adjust multiple jacking structures. The multiple jacking structures synchronously adjust their relative lengths in the vertical direction, thereby changing the relative position of the adjusting plate 2 in the installation cavity 4 in the vertical direction, so as to meet the requirement of stably placing test plates with different thicknesses of paint films in the installation cavity 4 for paint film impact testing, and it is also convenient to place the test plates in the installation cavity 4 or remove them from the installation cavity 4.

[0026] In this embodiment, four jacking structures are shown to be able to stably support the adjusting plate 2 to complete the paint film impact test; the number of jacking structures can also be adjusted according to actual needs.

[0027] Based on the above solution:

[0028] The jacking structure includes a moving cylinder 31 and an adjusting screw 32. The moving cylinder 31 is slidably arranged in the corresponding first installation channel in the vertical direction, and its top end is fixedly connected to the bottom of the adjusting plate 2; the adjusting screw 32 is rotatably arranged in the corresponding first installation channel in the vertical direction, one end of which is threadedly connected to the inside of the moving cylinder 31, and the other end is connected to the adjustment structure.

[0029] Specifically: the adjustment structure causes the multiple adjusting screws 32 to rotate synchronously, then the multiple moving cylinders 31 move synchronously towards or away from the corresponding adjusting screws 32, so as to adjust the distance between the adjusting plate 2 and the top wall in the installation cavity 4 to meet the usage requirements. Among them, a limit head is provided at the bottom end of each adjusting screw 32 to make the adjusting screw 32 only rotate without moving.

[0030] Furthermore, a second installation channel is opened in the base 1. The adjustment structure includes an adjusting screw rod 33 and a driven bevel gear 34. One end of the adjusting screw rod 33 is rotatably arranged in the second installation channel, and the other end passes through to the outside of the base 1. One driven bevel gear 34 is connected to each jacking structure, and each driven bevel gear 34 meshes with a driving bevel gear 35 fixedly connected to the adjusting screw rod 33.

[0031] In this embodiment:

[0032] The adjusting screw 32 in each jacking structure is connected to the corresponding driven bevel gear 34. When the adjusting screw rod 33 is rotated to make the driving bevel gears 35 rotate, the driving bevel gears 35 drive the corresponding driven bevel gears 34 to rotate. The driven bevel gears 34 drive the corresponding adjusting screws 32 to rotate, and the moving cylinders 31 move synchronously towards or away from the corresponding adjusting screws 32. The adjusting plate 2 moves in the vertical direction in the installation cavity 4 to adjust the distance between the adjusting plate 2 and the top wall of the installation cavity 4 to meet the usage requirements.

[0033] The adjusting screw rod 33 can be driven to rotate by holding the end of the adjusting screw rod 33 located outside the base 1, or a stepping motor connected outside the base 1 can be connected to the adjusting screw rod 33 to drive the adjusting screw rod 33 to rotate.

[0034] As Figure 1 shown, according to another embodiment of the present invention, the paint film impact tester further includes a guide cylinder 5, an impact part 6 and a height limit adjusting component 7; wherein, the guide cylinder 5 is arranged in the vertical direction and its bottom end is fixedly connected to the top of the base 1, and the inside of the guide cylinder 5 is communicated with the installation cavity 4 through a guide through hole opened on the top of the base 1; the impact part 6 is slidably arranged in the guide cylinder 5 in the vertical direction, and the height limit adjusting component 7 is connected between the top end of the guide cylinder 5 and the top end of the impact part 6 for limiting the impact part 6 at any height after lifting it.

[0035] The impact part 6 is moved vertically in the guide cylinder 5 to any height by the height limit adjusting component 7 and then limited. After the test plate is stably installed in the installation cavity 4, the restriction of the height limit adjusting component 7 on the impact part 6 is released, and the impact part 6 falls in the guide cylinder 5 and passes through the guide through hole to impact the test plate for paint film impact testing.

[0036] Specifically, the height limit adjusting component 7 includes a sealing plug 71, a guide rod 72 and a clamping jaw 73. The sealing plug 71 is connected to the top end of the guide cylinder 5. One end of the guide rod 72 is fixedly connected to the top end of the impact part 6 and the other end freely passes through the sealing plug 71. The clamping jaw 73 is connected to the sealing plug 71 and is used for clamping the guide rod 72.

[0037] The sealing plug 71 can be connected to the top end of the guide cylinder 5 in a threaded connection manner, which is convenient for the connection and disassembly between the sealing plug 71 and the guide cylinder 5; the tester holds the end of the guide rod 72 located outside the guide cylinder 5 to move the impact part 6 upward in the guide cylinder 5 to any required height, and then clamps and fixes the guide rod 72 through the clamping jaw 73; then the test plate is stably installed in the installation cavity 4, and then the clamping of the clamping jaw 73 on the guide rod 72 is released, and the impact part 6 freely falls in the guide cylinder 5 and passes through the guide through hole to impact the test plate for paint film impact testing.

[0038] Further, the height limit adjusting component 7 further includes a weight 74, and the weight 74 is used for sleeving on the guide rod 72 to increase the impact force. After the sealing plug 71 is disconnected from the guide cylinder 5, the number of weights 74 can be increased or decreased on the guide rod 72 according to requirements to adjust the impact force during the paint film impact testing process, so that the paint film impact testing is more comprehensive.

[0039] When this solution is used:

[0040] The tester holds the end of the guiding rod 72 outside the guiding cylinder 5 to move the impact part 6 upward in the guiding cylinder 5 to any required height, and then clamps and fixes the guiding rod 72 through the clamping jaw 73;

[0041] Slide the test plate into the installation cavity 4 from one end of the installation cavity 4 and place it on the adjusting plate 2. Then rotate the adjusting screw rod 33 to move the adjusting plate 2 upward until the test plate is clamped between the adjusting plate 2 and the inner top wall of the installation cavity 4;

[0042] Release the clamping and fixing of the guiding rod 72 by the clamping jaw 73. Then the impact part 6 freely falls in the guiding cylinder 5 and passes through the guiding hole to impact the test plate for film impact testing;

[0043] The tester then holds the end of the guiding rod 72 outside the guiding cylinder 5 to move the impact part 6 upward in the guiding cylinder 5 to disengage from the test plate. Then clamp and fix the guiding rod 72 again through the clamping jaw 73;

[0044] Rotate the adjusting screw rod 33 in the reverse direction to move the adjusting plate 2 downward. The test plate is disengaged from the clamping in the installation cavity 4, and the test plate can be removed from the installation cavity 4.
