Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a thermal transfer film performance detection system. Background Art

[0002] Thermal transfer film is a thin film that transfers information, such as patterns or text, to other surfaces through heating. It typically consists of a multi-layer structure, including a base layer, a release layer, a printed layer, and an adhesive layer. During actual use, thermal transfer film is inevitably subject to friction. Friction testing can determine how well the film's pattern and color withstand friction, or its wear resistance. This helps ensure product quality by preventing problems such as fading and wear of the thermal transfer pattern under normal use, thereby ensuring that the product meets expected quality standards.

[0003] The patent document with announcement number CN114813429B discloses a UV thermal transfer film performance detection system, which moves downward through a fixed ring. When the eight outer support blocks abut against the thermal transfer film, the eight outer support blocks move outward at the same time, thereby flattening the thermal transfer film until the fixed ring abuts against the thermal transfer film, thereby fixing the thermal transfer film on the upper end surface of the base.

[0004] Thermal transfer films are used in a variety of scenarios, and in actual use they come into contact with objects of various shapes and materials. However, the above-mentioned detection system needs to stop friction and replace other friction heads after completing friction detection, which affects detection efficiency. Summary of the Invention

[0012] Optionally, the conversion part includes a rotating ring, a rotating plate and a toggle plate. The top of the rotating ring is rotatably connected to the friction rod. The rotating plate is fixedly installed on the outer arc surface of the rotating ring. The toggle plate is arranged inside the pleat flattening assembly and is located on the moving path of the rotating plate. A positioning control assembly is arranged between the rotating ring and the gear.

[0013] Optionally, the positioning control component includes a positioning hole, a positioning clip and a fixing column. The positioning hole is opened at the top of the gear. There are multiple positioning holes, which are distributed in a ring at equal angles on the top of the gear. The fixing column is fixedly installed inside the friction rod and above the gear. The positioning clip is fixedly installed at the bottom of the fixing column, and the positioning hole is clamped with the positioning clip.

[0014] Optionally, an elastic sheet is fixedly installed inside the swivel, and the elastic sheet is meshed with the gear. A plurality of elastic sheets are provided, and are distributed in a ring with equal angles on the inner arc surface of the swivel. An obstruction block that obstructs the elastic sheet is fixedly installed on the inner arc surface of the swivel in the clockwise direction of the elastic sheet, and a coil spring is elastically connected between the top of the swivel and the friction rod.

[0015] Optionally, when the swivel rotates counterclockwise, the obstruction block abuts against the side of the elastic sheet, and the swivel rotates synchronously with the gear; when the swivel rotates clockwise, the elastic sheet bends and separates from the obstruction block, and the gear does not rotate synchronously with the swivel.

[0016] Optionally, the wrinkle flattening assembly includes a base plate, a second pressure plate and a friction track. The base plate is fixedly installed on the top of the friction detection body.

[0019] Compared with the prior art, this application has at least one of the following beneficial technical effects:

[0020] The present invention changes the position of the pressure block by rotating the gear to switch the friction block in contact with the thermal transfer film. The friction layer material at the bottom of each friction block is different. Due to the different lengths of each friction block, the contact pressure between each friction block and the thermal transfer film is different under the downward pressure of the pressure block, so that the friction force between each friction block and the thermal transfer film is the same. While controlling the maximum detection friction force, different friction modes are switched to simulate a variety of thermal transfer film application scenarios.

[0021] Furthermore, elastic sheets and obstruction blocks are used to ensure that the gear can only rotate in one direction, and multiple positioning holes correspond to multiple friction blocks. When the positioning clip is inserted into the positioning hole, there is a friction block that can move completely down and contact the thermal transfer film. The angle of the gear is positioned by the positioning hole and the positioning clip to prevent the gear from rotating too much and the friction block from contacting the thermal transfer film.

[0022] Furthermore, the squaring strip is moved along the thermal transfer film to flatten the wrinkles on the thermal transfer film to prevent the wrinkles from affecting the friction test. The smear roller moves along the thermal transfer film, and the diffusion cotton strip absorbs alcohol and diffuses it on its surface. The smear roller continuously contacts the diffusion cotton strip during the rolling process, thereby smearing alcohol on the thermal transfer film to test the coating adhesion of the thermal transfer film.

[0023] Furthermore, alcohol is used together with a smear roller to clean the attachments on the surface of the thermal transfer film to avoid the presence of attachments causing changes in the detection friction and resulting in detection errors. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] Example 1

[0040] This embodiment provides a thermal transfer film performance detection system. Figure 1 As shown, it includes a friction detection body 1, a control switch 2 is fixedly installed on the front of the friction detection body 1, a height lifting rod 3 is fixedly installed on the top of the friction detection body 1, a wear-resistant detection component 4 is arranged on the side of the height lifting rod 3, and the height lifting rod 3 adjusts the height of the wear-resistant detection component 4.

[0041] like Figures 2 to 4As shown, the wear-resistant detection assembly 4 includes a reciprocating telescopic rod 41, a friction rod 42, a friction block 43, a support member, a pressure block 46, a gear 47, a rotary column 48, and a conversion member. The reciprocating telescopic rod 41 is fixedly mounted on the protruding end of the height lifting rod 3. The end of the reciprocating telescopic rod 41 is fixedly mounted with two symmetrically arranged friction rods 42. The interior of the friction rod 42 slides up and down to connect with the friction block 43. A support member is set on the side of the friction block 43. The support member includes a pressure plate 1 44 and a support spring 45. The pressure plate 1 44 is fixedly mounted on the end of the friction block 43 and slides up and down inside the friction rod 42. The bottom of the pressure plate 1 44 is elastically connected to the friction rod 42 with a support spring 45. The friction block 43 is supported by the pressure plate 1 44 and the support spring 45 to control its height.

[0042] The friction rod 42 is moved back and forth by extending and retracting the height lifting rod 3 to test the wear resistance of the thermal transfer film. A wrinkle flattening component 5 for placing the thermal transfer film is provided on the top of the friction testing body 1, and the bottom of the friction block 43 is in contact with the thermal transfer film.

[0043] The inside of the friction rod 42 is connected to the pressure block 46 for sliding left and right. There are multiple friction blocks 43, and a friction layer of different materials is fixedly installed on the bottom of each friction block 43. The length of each friction block 43 is different. The pressure block 46 is located directly above one of the friction blocks 43. The height of this friction block 43 is lower than that of the other friction blocks 43. The top of the friction block 43 is provided with a slope, and the bottom of the pressure block 46 is provided with a symmetrically arranged slope. The inclination angle of the slope of the pressure block 46 is the same as the inclination angle of the slope of the friction block 43.

[0044] like Figure 3 and Figure 4 As shown, since friction layers of different materials are fixedly installed at the bottom of each friction block 43, the friction force between each friction block 43 and the thermal transfer film is different under the same pressure, and since the length of each friction block 43 is different, the displacement caused by the pressing block 46 on different friction blocks 43 is different, so that the pressure between each friction block 43 and the thermal transfer film is different, and the friction layer materials at the bottom of each friction block 43 are different, so that the friction force between the friction layer at the bottom of each friction block 43 and the thermal transfer film is the same. While controlling the maximum detection friction force, different friction modes are converted to simulate a variety of thermal transfer film application scenarios.

[0045] The friction rod 42 is internally connected to a gear 47, and a rotary post 48 is fixedly installed at the bottom of the gear 47 and offset from the center of the circle. The arc surface of the rotary post 48 contacts the pressure block 46. A symmetrically arranged vertical plate is fixedly installed on the top of the pressure block 46. The rotary post 48 is located between the two vertical plates. A transverse track is opened inside the friction rod 42, and the pressure block 46 slides in the transverse track.

[0046] like Figure 5 and Figure 6 As shown, the conversion part includes a rotating ring 49, a rotating plate 410 and a toggle plate 411. The top of the rotating ring 49 is rotatably connected to the friction rod 42. The rotating plate 410 is fixedly installed on the outer arc surface of the rotating ring 49. The toggle plate 411 is arranged inside the pleat flattening component 5 and is located on the moving path of the rotating plate 410. A positioning control component 6 is arranged between the rotating ring 49 and the gear 47.

[0047] When the inspection of one type of friction layer friction heat transfer film is completed, the height lifting rod 3 is fully retracted to move the rotating plate 410 to the toggle plate 411, and the toggle plate 411 is used to drive the rotating plate 410 to rotate, thereby rotating the rotating ring 49 and the gear 47. The rotation of the gear 47 causes the rotating column 48 to drive the pressure block 46 to rotate. The pressure block 46 changes its position and uses the inclined surface to squeeze the other friction block 43 downward. At this time, the friction block 43 separated from the pressure block 46 is reset under the elastic force of the support spring 45, so there is always only one friction block 43 in contact with the heat transfer film.

[0048] In this embodiment, the position of the pressure block 46 is changed by rotating the gear 47 to switch the friction block 43 in contact with the thermal transfer film. Since a friction layer of different material is fixedly installed on the bottom of each friction block 43, the friction force between each friction block 43 and the thermal transfer film is different under the same pressure. Due to the different lengths of each friction block 43, the contact pressure between each friction block 43 and the thermal transfer film under the downward pressure of the pressure block 46 is different, so that the friction force between each friction block 43 and the thermal transfer film is the same. While controlling the maximum detection friction force, different friction modes are switched to simulate a variety of thermal transfer film application scenarios.

[0049] Example 2

[0050] Based on Example 1, this example proposes a thermal transfer film performance detection system, such as Figure 5 and Figure 6 As shown, the positioning control component 6 includes a positioning hole 61, a positioning clip 62 and a fixing column 63. The positioning hole 61 is opened at the top of the gear 47. There are three positioning holes 61, and they are distributed at equal angles in a ring on the top of the gear 47. The fixing column 63 is fixedly installed inside the friction rod 42 and above the gear 47. The positioning clip 62 is fixedly installed at the bottom of the fixing column 63, and the positioning hole 61 is engaged with the positioning clip 62.

[0051] The positioning hole 61 is engaged with the positioning clip 62 to prevent the rotating plate 410 from moving too much after being toggled by the toggle plate 411, which may cause the friction block 43 to be unable to move completely downward and unable to contact the thermal transfer film. Multiple positioning holes 61 correspond to multiple friction blocks 43 respectively, so that the friction block 43 can always move completely downward and contact the thermal transfer film.

[0052] An elastic sheet 64 is fixedly installed inside the swivel 49, and the elastic sheet 64 is meshed with the gear 47. A plurality of elastic sheets 64 are provided, and are distributed at equal angles in a ring shape on the inner arc surface of the swivel 49. An obstruction block 65 that obstructs the elastic sheet 64 is fixedly installed on the inner arc surface of the swivel 49 and in the clockwise direction of the elastic sheet 64. A coil spring is elastically connected between the top of the swivel 49 and the friction rod 42, and the coil spring is used to reset the swivel 49 and the rotating plate 410.

[0053] When the swivel 49 rotates counterclockwise, the block 65 abuts against the side of the elastic plate 64, causing the swivel 49 to rotate synchronously with the gear 47. When the swivel 49 rotates clockwise, the elastic plate 64 bends and separates from the block 65, preventing the gear 47 from rotating synchronously with the swivel 49. This prevents the rotating plate 410 from being moved by the toggle plate 411 and the height adjustment rod 3 from extending to perform the second type of friction. This prevents the rotating plate 410 from moving and being toggled by the toggle plate 411 again, causing the gear 47 to rotate backward and preventing the friction type from being switched. The positioning hole 61 engages with the positioning clip 62 to act as a rotational resistance to the gear 47.

[0054] In this embodiment, an elastic sheet 64 and an obstruction block 65 are used to ensure that the gear 47 can only rotate in one direction. A plurality of positioning holes 61 correspond to a plurality of friction blocks 43 respectively. When the positioning clip 62 is inserted into the positioning hole 61, there is a friction block 43 that can move completely downward and contact the thermal transfer film, and the positioning hole 61 and the positioning clip 62 are engaged as the rotation resistance of the gear 47, preventing the elastic sheet 64 from driving the gear 47 to rotate when the swivel 49 rotates clockwise.

[0055] Example 3

[0056] Based on the above embodiment 1 or 2, this embodiment proposes a thermal transfer film performance detection system, such as Figure 7 As shown, the wrinkle flattening assembly 5 includes a base plate 51, a second pressure plate 52, and a friction track 53. The base plate 51 is fixedly mounted on the top of the friction testing body 1. A thermal transfer film is placed on the top of the base plate 51, and the top of the base plate 51 covers the second pressure plate 52. The base plate 51 and the second pressure plate 52 sandwich the thermal transfer film. Two symmetrical friction tracks 53 are provided on the top of the second pressure plate 52. The friction rod 42 extends from the friction tracks 53 to the bottom of the second pressure plate 52 and contacts the thermal transfer film. The toggle plate 411 is fixed to the friction tracks 53. The base plate 51 and the second pressure plate 52 cooperate to fix the thermal transfer film, preventing the thermal transfer film from moving when the friction block 43 rubs the thermal transfer film, thereby preventing normal wear resistance testing.

[0057] like Figure 8 and Figure 9As shown, the internal rotation connection of the second pressure plate 52 is connected to two symmetrically arranged rotating rods 54, the ends of the rotating rods 54 are bent, the side of the rotating rods 54 is rotationally connected to the spreading bar 55, the internal rotation of the spreading bar 55 is connected to the smear roller 56, and a torque spring is elastically connected between the rotating rods 54 and the second pressure plate 52. The spreading bar 55 and the smear roller 56 are in contact with the thermal transfer film, and a receiving cavity for accommodating the rotating rods 54 and the spreading bar 55 is opened on the top inner wall of the bottom plate 51.

[0058] Because the end of the rotating rod 54 is bent, it is subjected to a horizontal force when the second pressure plate 52 is lowered. At this time, the squaring bar 55 moves along the thermal transfer film, flattening any wrinkles on the film and preventing them from affecting the friction test. After the bottom plate 51 and the second pressure plate 52 are combined, the bottom plate 51 and the second pressure plate 52 completely clamp and secure the thermal transfer film, preventing the friction test from causing the thermal transfer film to move. After the bottom plate 51 and the second pressure plate 52 are combined, the receiving chamber accommodates the rotating rod 54 and the squaring bar 55.

[0059] A diffusion cotton strip 57 in contact with the smear roller 56 is fixedly installed inside the spreading bar 55. An alcohol tank 58 is opened inside the second pressure plate 52. The diffusion cotton strip 57 extends along the spreading bar 55 and the rotating rod 54 into the alcohol tank 58. As the smear roller 56 moves along the thermal transfer film, the diffusion cotton strip 57 absorbs alcohol and diffuses it on its surface. During the rolling process of the smear roller 56, it constantly contacts the diffusion cotton strip 57, thereby smearing alcohol on the thermal transfer film to test the coating adhesion of the thermal transfer film. At the same time, the alcohol is used together with the smear roller 56 to clean the attachments on the surface of the thermal transfer film.

[0060] In this embodiment, the squaring strip 55 is moved along the thermal transfer film to flatten the wrinkles on the thermal transfer film to prevent the wrinkles from affecting the friction detection. The smear roller 56 moves along the thermal transfer film, and the diffusion cotton strip 57 absorbs alcohol and diffuses it on its surface. The smear roller 56 continuously contacts the diffusion cotton strip 57 during the rolling process, thereby smearing alcohol on the thermal transfer film to detect the coating adhesion of the thermal transfer film. At the same time, alcohol is used together with the smear roller 56 to clean the attachments on the surface of the thermal transfer film to avoid the presence of attachments causing changes in the detected friction and generating detection errors.

[0061] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
