Description

Technical Field

[0001] The utility model relates to the field of sample spraying, in particular to a fixing device for sample spraying. Background Art

[0002] In the fields of coatings, adhesives, etc., it is necessary to make samples for performance testing (such as adhesion, durability, hardness, etc.), that is, to coat the material to be tested (such as coatings, adhesives) on the plate; and each sample can only be used for one performance test, and multiple performance tests require multiple samples; in order to ensure the consistency of samples during performance testing (as a quantitative measure), all samples need to be prepared under the same conditions, that is, the performance of the samples being tested is consistent (such as coating thickness), etc.

[0003] When preparing the sample, whether it is a metal plate (stainless steel plate) or a non-metallic material (such as a plastic sample), if the plate is large and heavy, it will be placed on a grid frame / plate for spraying, so that the plate will not be blown away, blown away, displaced, or fall off the sample frame by the high-pressure compressed air during spraying. However, under normal circumstances, the plate is relatively light and small, such as a 70mm*150mm plate; whether it is a metal or plastic material, when it is sprayed with high-pressure compressed air, the plate will be displaced by the air pressure and the impact of the material, and even fall off the sample frame.

[0004] In order to avoid the displacement of the panels during spraying, before spraying the panels, first wrap many circles of double-sided tape or single-sided tape with the adhesive side facing outward (end bonding) on ​​a large iron plate or grid frame / board, then adhere the panels to be sprayed on the tape, and then spray. Or in order to avoid the displacement of the panels during spraying, before spraying the panels, first arrange a large number of panels to be sprayed on the frame, support rod, support strip of the iron plate or grid frame / board, and then use tape to bond the edges of adjacent panels, and wrap many circles around the iron plate or grid frame / board to ensure that the panels are integrated and fixed together with the iron plate or grid frame / board; the tape can also be replaced by aluminum foil.

[0005] When spraying paint or adhesive on the panels in the above manner, a lot of preparation work is required to fix the panels before spraying, and the fixing operation is cumbersome; after spraying, in order to remove each sample, the tape wrapped around the sample and the frame, support rod, and support strip must be removed first, because the coating film has been adhered, which further enhances the physical properties of the tape (such as strength, etc.), making it difficult to remove, and sometimes tools are required to remove it; and after the tape or aluminum foil is removed, it cannot be reused and the site needs to be cleaned up, which not only increases material costs, but also increases labor costs.

[0006] Therefore, in order to solve the above problems faced by production and to save resources and costs, it is necessary to optimize the spraying support device. Utility Model Content

[0007] The purpose of the utility model is to provide a fixing device for sample spraying in response to the above-mentioned problems, so as to reduce the complexity of operation, effectively improve the spraying efficiency, and also be reusable, thereby reducing the generation of waste (waste tape, aluminum foil, etc.), thereby effectively reducing costs.

[0013] Furthermore, one end of the base is provided with a limiting structure capable of abutting against the connecting piece.

[0014] Furthermore, if the base is a plate body with mesh holes, the limiting structure is a bent section or a limiting column of the plate; if the base is a grid body, the limiting structure is an extended section or a limiting column of the outermost strip in the grid body.

[0015] Furthermore, the locking member is a second damping pad to increase the damping of sliding between the plate and the clamping groove; or the locking member is a second friction plate, and a second elastic member is arranged between the second friction plate and the inner wall of the clamping groove; or the locking member is a detachable plug arranged at both ends of the clamping groove.

[0016] Furthermore, the second damping pad is an elastic pad made of elastomeric rubber.

DETAILED DESCRIPTION

[0031] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0032] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0033] Example 1

[0034] like Figure 1-Figure 7 As shown, a fixing device for spraying a sample comprises a base 3, on which a plurality of clamping bodies 1 for clamping a plate are mounted, the clamping body 1 comprises a connecting member 2 connected to the base 3, a clamping member is fixed on the connecting member 2, and clamping grooves 11 for mounting the plate are provided on both sides of the clamping member, which is equivalent to the clamping member being in an "I" shape; adjacent clamping bodies 1 cooperate to clamp the plate, and a locking member for locking the sample in the clamping groove 11 is provided in the clamping groove 11.

[0035] During use, the panel to be sprayed is placed between the clamping grooves 11 of two adjacent clamping bodies 1. The panel is supported and fixed by the clamping grooves 11, thereby fixing the panel and effectively preventing the panel from moving during the spraying process.

[0036] In this embodiment, the fixing device clamps the panel by cooperating with the adjacent clamping body 1, and locks the template in the clamping groove 11 by the locking member, thereby achieving rapid fixation of the panel and being unaffected by the material of the panel, that is, the panel can be made of metal, plastic, ceramic, or wood, and has universal applicability.

[0037] In this embodiment, the two ends of the clamping groove 11 are not closed or can be opened. When installing the panel, it is only necessary to insert the panel from the two ends of the clamping groove 11 to place the panel in the clamping groove 11; after the panel is placed in the clamping groove 11, the panel is locked by the locking member.

[0038] In this embodiment, the fixing device fixes the plate by the clamping body 1, and there is no need to use tape or the like for fixing. It can be reused and the generation of waste tape is avoided, thereby effectively reducing material costs and labor costs.

[0039] In this embodiment, the fixing device can fix multiple panels of the same specification at one time, thereby realizing batch production of samples.

[0040] Example 2

[0041] On the basis of Example 1, a feasible specific implementation method of the "base 3" is further proposed.

[0042] In a first embodiment, the base 3 is a plate without meshes 31 , and the base 3 is only applicable to the case where the plate to be sprayed can completely cover the base 3 .

[0043] The second implementation method, such as Figure 5 As shown, the base 3 is a plate body with mesh holes 31, and the specific manufacturing method is to evenly open the mesh holes 31 directly on the plate; on the one hand, the mesh holes 31 can reduce the material of the base 3, thereby reducing the weight of the entire device and facilitating transportation; on the other hand, the base 3 is not only suitable for the situation where the plate to be sprayed can completely cover the base 3, but also suitable for the situation where the plate to be sprayed cannot completely cover the base 3; for the situation where the plate cannot completely cover the base 3, the existence of the mesh holes 31 can enable the paint that has not fallen on the plate to pass through the mesh holes 31, and will not rebound and fall on the surface of the plate after acting on the surface of the base 3, affecting the quality of sample manufacturing.

[0044] The third implementation method, such as Figure 6 As shown, the base 3 is a grid body composed of hard strips, and the effect of the grid body is the same as that of a plate body with meshes 31 as the base 3, which will not be further explained here.

[0045] It should be noted that, for the grid body of the third embodiment, it is preferred that all edges in the grid body are in the same plane, that is, there is no stacking of the strips that make up the grid; when using the grid body, for the installation of the connecting member 2, especially the sliding connection between the connecting member 2 and the base 3, it can be ensured that the connecting member 2 can be smoothly inserted into the base 3 or slid out from the base 3 without any jamming.

[0046] Example 3

[0047] On the basis of any one of the implementations in Examples 1-2, a specific implementation of the "connection structure between the connector 2 and the base 3" is further proposed.

[0048] In the first embodiment, the connecting member 2 is fixedly connected to the base 3, and this embodiment is only applicable to samples of a certain specification.

[0049] The second implementation method, such as Figure 1-Figure 4 As shown, the connecting member 2 is slidably connected to the base 3 to adjust the spacing between adjacent clamping bodies 1, thereby adjusting the spacing between the clamping grooves 11, so as to adapt to panels of different specifications. Figure 1-Figure 2As shown, the bottom sides of the connector 2 have slots 21 that are slidably connected to the base 3. The base 3 is located between the two slots 21 and the two sides of the base 3 are located in the slots 21. The sliding connection between the connector 2 and the base 3 is achieved by the sliding connection between the slots 21 and the base 3, and the connector 2 is effectively prevented from being separated from the base 3 in a direction perpendicular to the surface of the base 3, that is, the slots 21 play a limiting role. Or, as Figure 3-Figure 4 As shown, slide grooves 32 are provided on both sides of the base 3, and both sides of the bottom of the connecting member 2 are respectively located in the two slide grooves 32 and are slidably connected with the slide grooves 32 to realize the sliding connection between the connecting member 2 and the base 3, and effectively prevent the connecting member 2 from separating from the base 3 in a direction perpendicular to the surface of the base 3, that is, the slide grooves 32 play a limiting role.

[0050] For the second embodiment, when spraying and making the sample, in order to prevent the connecting member 2 from sliding out of the original position along the base 3 and causing the plate to be out of the clamping groove 11; therefore, a first damping pad 4 is provided in the slot 21 (slide groove 32), and after the base 3 enters the slot 21 (or the two sides of the bottom of the connecting member 2 enter the slide groove 32), the first damping pad 4 is squeezed to increase the sliding damping between the slot 21 of the connecting member 2 and the base 3 (the sliding damping between the slide groove 32 on the base 3 and the connecting member 2), thereby reducing the possibility of movement of the connecting member 2; or the slot 21 A first friction plate 9 is arranged in the (slide groove 32), and a first elastic member 91 is arranged between the first friction plate 9 and the inner wall of the slot 21 (slide groove 32). After the base 3 enters the slot 21 (or the two sides of the bottom of the connecting member 2 enter the slide groove 32), the first friction plate 9 is located between the first elastic member 91 and the base 3 (connecting member 2). The first friction plate 9 is acted upon by the elastic force of the first elastic member 91 and pressed against the base 3 (connecting member 2), so that there is sufficient friction between the base 3 (connecting member 2) and the first friction plate 9, thereby reducing the possibility of movement of the connecting member 2.

[0051] In the second embodiment, the first damping pad 4 can be an elastic pad made of elastomeric rubber; the first elastic member 91 can be an elastic pad or a spring made of elastomeric rubber; the first friction plate 9 can be a long strip plate body or a block with a large surface roughness. If it is a block, both ends of the slot 21 (slide slot 32) need to exist.

[0052] Example 4

[0053] Based on any one of the implementation methods in Examples 1-3, a feasible implementation method is further proposed.

[0054] One end of the base 3 is provided with a limiting structure 5 that can abut against the connecting piece 2. The existence of the limiting structure 5 does not allow the clamping body 1 to slide out from this end of the base 3, so that the base 3 can also fix the plate when placed vertically, increasing the application scenarios of the fixing device.

[0055] Specifically, Figure 1-Figure 7 As shown, if the base 3 is a plate body with mesh 31, the limiting structure 5 is a bending section or a limiting column of the plate; if the base 3 is a grid body, such as Figure 5 As shown, the limiting structure 5 is an extension section or a limiting column of the outermost strip member in the grid body.

[0056] The limiting column can be installed on the upper surface or lower surface of the base 3 in a posture perpendicular to the upper and lower surfaces of the base 3; or / and the limiting column can be installed on the side of the base 3 (for the grid body, equivalent to the extension section) in a posture parallel to the upper and lower surfaces of the base 3.

[0057] In this embodiment, the bending length of the bending section, the length of the limiting column or the extension section all need to be greater than the slot width of the locking slot 21 to ensure the limiting effect.

[0058] Example 5

[0059] On the basis of any one of the implementations in Examples 1-4, an implementation of a "locking member" is further proposed.

[0060] The first implementation method, such as Figure 2 As shown, the locking member is a second damping pad 7. After the panel is installed, the second damping pad 7 is squeezed, thereby increasing the friction damping of the sliding between the panel and the clamping groove 11, thereby reducing the possibility of movement of the panel and ensuring the stability of the position of the panel.

[0061] The second implementation method, such as Figure 3 , Figure 4 As shown, the locking member is a second friction plate 8, and a second elastic member 81 is arranged between the second friction plate 8 and the inner wall of the clamping groove 11; after the plate enters the clamping groove 11, the second friction plate 8 is located between the second elastic member 81 and the plate, and the second friction plate 8 is pressed against the plate by the elastic force of the second elastic member 81, so that there is sufficient friction between the plate and the second friction plate, thereby reducing the possibility of movement of the plate and ensuring the stability of the position of the plate.

[0062] The third implementation method, such as Figure 1 As shown, the locking member is a detachable plug 6 arranged at both ends of the clamping groove 11. The plug 6 closes the two ends of the clamping groove 11 to prevent the plate from escaping from the clamping groove 11 from both ends of the clamping groove 11, so that the plates in the clamping groove 11 are constrained to each other, thereby reducing the possibility of movement of the plates and ensuring the stability of the position of the plates; the plug 6 is detachable so as not to affect the installation of the plates.

[0063] In this embodiment, the second damping pad 7 can be an elastic pad made of elastomeric rubber; the second elastic member 81 can be an elastic pad or a spring made of elastomeric rubber; the second friction plate 8 can be a long strip plate body or a block with a large surface roughness. If it is a block, both ends of the slot 21 need to exist.

[0064] It should be noted that, for the third embodiment, in order to avoid overlap of the plates placed in the clamping groove 11, the groove width of the clamping groove 11 should be greater than or equal to the thickness of the plate and less than 2 times the thickness of the plate. For the first and second embodiments, since the second damping pad 7, the second elastic member 81 and the second friction plate 8 can make up for the unfilled gap in the clamping groove 11, there is no need to specifically design the groove width of the clamping groove 11.

[0065] It should be noted that if Figure 7 As shown, the depth of the clamping groove 11 can be designed adaptively, retaining a sufficient size to prevent the plate in the clamping groove 11 from being separated from the clamping groove 11 in an inclined posture; specifically, the groove depth is h, the plate length (the distance between the bottoms of adjacent clamping grooves 11) is a, and the groove width is b, then it should satisfy

[0066] In a feasible implementation manner, the end of the second damping pad 7 has an outward arc-shaped guide section to facilitate the installation of the panel.

[0067] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
