Description

Technical Field

[0001] This utility model relates to the field of friction testing technology, specifically to a surface friction testing device for tanks. Background Technology

[0002] A can is a large-mouthed container used for holding things or for holding or cooking food. In daily life, aluminum cans are a common can structure, and labels or patterns are usually printed on the surface of aluminum cans to describe the contents of the can and remind people of the shelf life.

[0003] During transportation and storage, cans are usually stacked in multiple layers with adjacent can surfaces touching to ensure the overall structure is stable. Therefore, during transportation and storage, the can surfaces are subject to friction, which can cause printed labels or patterns to become blurred or fall off, affecting the can's description and brand image.

[0004] Meanwhile, since the can body can be made of different materials, and the printed coatings on different materials have different frictional characteristics, there are certain technical difficulties in how to use printed coatings with different frictional characteristics for can bodies made of different materials.

[0005] Chinese patent CN205679473U discloses a friction testing fixture and a friction testing instrument, including a worktable. The worktable is provided with a test plate for fixing and placing the test object and a driving component for driving the test plate to reciprocate along the length direction of the worktable. The worktable is provided with a test arm and a sliding kit for sliding the test arm along the width direction of the worktable.

[0006] The friction testing instrument disclosed above achieves friction testing between the test object and the test arm by moving the test object. When it is necessary to perform friction testing on the surface of the tank, it can only simulate the friction test between the surface of the tank and the test arm, and it is difficult to simulate the friction between adjacent tanks, thus affecting the friction test effect of the tank surface. Utility Model Content

[0007] The present invention aims to overcome the defects in the prior art and provide a simple structure, convenient clamping, and applicable device for testing the surface friction of tanks of different sizes.

[0008] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a surface friction testing device for a tank, comprising a test platform and a first tank to be tested placed on the test platform; the test platform is provided with a directional guide group for positioning the first tank to be tested, the top of the directional guide group is provided with a sliding plate slidably connected to the directional guide group, and a reciprocating component for driving the sliding plate to move back and forth is installed on the test platform; a clamping seat is installed on the sliding plate and moves synchronously with the sliding plate, and a second tank to be tested that rubs against the first tank to be tested is clamped on the clamping seat.

[0009] As a preferred embodiment of this utility model, the directional guide group consists of two parallel directional baffles, the first test tank is clamped between the two directional baffles, and the top of the directional baffle is provided with a directional guide rail arranged along the length direction of the directional baffle.

[0010] As a preferred embodiment of this utility model, the bottom of the sliding plate is provided with a directional sliding rail adapted to the directional guide rail, and the bottom of the sliding plate cooperates with two directional guide rails at the same time.

[0011] As a preferred embodiment of this utility model, an arc-shaped support body for clamping the first test tank is installed on the inner side of the directional baffle, and fixing bolts for fixing the arc-shaped support body are provided on the directional baffle.

[0012] As a preferred embodiment of this utility model, the reciprocating assembly includes a support base and a roller mounted on the support base, and a reciprocating push rod connected to the sliding plate is mounted on the roller.

[0013] In a preferred embodiment of this utility model, the center of the roller is fixedly connected to the support base, and the reciprocating push rod is hinged to the non-center of the roller.

[0014] As a preferred embodiment of this utility model, the support base is equipped with a drive motor for driving the roller to rotate, and the drive motor is equipped with a speed encoder for recording the rotation speed of the roller.

[0015] As a preferred embodiment of this utility model, the end of the sliding plate is provided with a connecting seat that is rotatably connected to the reciprocating push rod.

[0016] As a preferred embodiment of this utility model, the clamping seat is provided with clamping rods arranged opposite to each other, and the clamping rods are provided with rubber sleeves for fitting the second test tank.

[0017] In a preferred embodiment of this utility model, the surface of the first test tank is located above the top of the directional guide group, and the first test tank and the second test tank are arranged intersectingly.

[0018] Compared with the existing technology, by setting up a guide group to position and clamp the first test tank, and installing a clamping seat that can slide along the guide group, the reciprocating component drives the clamping seat and the second test tank on the clamping seat to reciprocate, thereby achieving mutual friction between the second test tank and the first test tank under the reciprocating movement, thus realizing the friction test of the first test tank and the second test tank.

Detailed Implementation

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, a surface friction testing device for a can includes a test platform 1 and a first can 6 to be tested placed on the test platform 1; the test platform 1 is provided with a directional guide group 2 for positioning the first can 6 to be tested, the top of the directional guide group 2 is provided with a sliding plate 3 slidably connected to the directional guide group 2, and the test platform 1 is equipped with a reciprocating assembly 4 for driving the sliding plate 3 to move back and forth; the sliding plate 3 is equipped with a clamping seat 5 that moves synchronously with the sliding plate 3, and the clamping seat 5 holds a second can 7 to be tested that rubs against the first can 6 to be tested.

[0025] The first test tank 6 is placed on the test bench 1. Under the action of the guide group 2, the first test tank 6 is positioned and clamped, so that the first test tank 6 is stably placed on the test bench 1.

[0026] The first test tank 6 is placed along the length of the guide group 2, and the sliding plate 3 also slides along the length of the guide group 2. During the sliding of the sliding plate 3, the clamping seat 5 is slid simultaneously, thereby slid the second test tank 7 along the length of the first test tank 6, thus realizing the mutual friction between the first test tank 6 and the second test tank 7.

[0027] The directional guide group 2 consists of two parallel directional baffles 21. The first test tank 6 is clamped between the two directional baffles 21, and the top of the directional baffle 21 is provided with a directional guide rail 22 arranged along the length direction of the directional baffle 21.

[0028] The directional baffle 21 is vertically set on the test bench 1. The first test tank 6 is placed between the two directional baffles 21 and is placed along the length of the directional baffle 21. Therefore, under the action of the two directional baffles 21, the radial direction of the first test tank 6 is limited.

[0029] The bottom of the sliding plate 3 is provided with a directional slide rail 31 that is adapted to the directional guide rail 22, and the bottom of the sliding plate 3 cooperates with two directional guide rails 22 at the same time. Under the action of the directional slide rail 31 and the directional guide rail 22, the sliding direction of the sliding plate 3 on the directional baffle 21 is limited and guided, ensuring that the second test tank 7 always performs reciprocating motion on the same track under the action of the directional slide rail 31 and the directional guide rail 22.

[0030] An arc-shaped support 23 for clamping the first test tank 6 is installed on the inner side of the directional baffle 21, and a fixing bolt 24 for fixing the arc-shaped support 23 is provided on the directional baffle 21.

[0031] The arc-shaped support 23 abuts against the surface of the first test tank 6, and the arc-shaped support 23 forms an arc-shaped structure for contact area with the first test tank 6. Under the action of the arc-shaped support 23, the first test tank 6 is supported. The arc-shaped support 23 can be made of rubber to increase the coefficient of friction between the arc-shaped support 23 and the first test tank 6, ensuring the placement stability of the first test tank 6.

[0032] Meanwhile, under the action of the fixing bolts 24, different sizes of arc-shaped support bodies 23 can be replaced on the positioning baffle 21, thereby satisfying the support of the first test tank 6 of different sizes.

[0033] The reciprocating assembly 4 includes a support base 41 and a roller 42 mounted on the support base 41. A reciprocating push rod 43 connected to the sliding plate 3 is mounted on the roller 42. The center of the roller 42 is fixedly connected to the support base 41, and the reciprocating push rod 43 is hinged to the non-center of the roller 42. The end of the sliding plate 3 is provided with a connecting seat 44 that is rotatably connected to the reciprocating push rod 43.

[0034] The reciprocating assembly 4 forms a crank-slider structure. During the rotation of the roller 42, it drives the reciprocating push rod 43 to reciprocate. Under the action of the connecting seat 44 and the directional guide group 2, the reciprocating movement of the reciprocating push rod 43 is transmitted to the sliding plate 3. Under the action of the directional guide group 2, the movement of the sliding plate 3 is limited and guided, so as to realize the reciprocating movement of the sliding plate 3 on the same linear track.

[0035] A drive motor 45 for driving the roller 42 to rotate is installed on the support base 41, and a speed encoder 46 for recording the rotation speed of the roller 42 is provided on the drive motor 45. The rotation speed of the roller 42 is recorded under the action of the speed encoder 46. The rotation speed of the roller 42 is the number of reciprocations of the sliding plate 3, which is also the number of frictions between the first test tank 6 and the second test tank 7.

[0036] The clamping base 5 is provided with clamping rods 51 arranged opposite to each other. The clamping rods 51 are provided with rubber sleeves 52 for fitting the second test tank 7. The clamping base 5 is provided with two clamping rods 51 arranged opposite to each other. The two clamping rods 51 are respectively arranged at both ends of the second test tank 7. The rubber sleeves 52 are fixedly connected to the corresponding clamping rods 51. Under the action of the rubber sleeves 52, the ends of the second test tank 7 are covered, thereby realizing the positioning and clamping of the second test tank 7 under the action of the two oppositely arranged rubber sleeves 52. Under the action of the rubber, the friction coefficient between the rubber sleeves and the second test tank 7 is increased, preventing the second test tank 7 from rotating.

[0037] The surface of the first test tank 6 is located above the top of the guide group 2, and the first test tank 6 and the second test tank 7 are arranged crosswise and perpendicularly to each other to ensure friction between the first test tank 6 and the second test tank 7.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0039] Although this document frequently uses reference numerals from the accompanying drawings, such as test bench 1, directional guide assembly 2, directional baffle 21, directional guide rail 22, arc-shaped support 23, fixing bolt 24, sliding plate 3, directional slide rail 31, reciprocating assembly 4, support seat 41, roller 42, reciprocating push rod 43, connecting seat 44, drive motor 45, speed encoder 46, clamping seat 5, clamping rod 51, rubber sleeve 52, first test tank 6, second test tank 7, etc., the possibility of using other terms is not excluded.
