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 film that can transfer information such as patterns or text to the surface of other materials by heating. It is usually composed of a multi-layer structure, including a base layer, a release layer, a printing layer, and an adhesive layer. Thermal transfer films will inevitably be subjected to friction during actual use. Through friction testing, it is possible to determine the degree to which the patterns and colors of the thermal transfer films can withstand friction, that is, their wear resistance. This helps to ensure product quality and avoid problems such as fading and wear of the thermal transfer patterns under normal use, thereby ensuring that the products can meet the 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 will come into contact with objects of various shapes and materials during actual use. However, the above-mentioned detection system needs to stop friction and replace other friction heads after completing friction detection, which affects detection efficiency.

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0027] 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.

[0028] like Figures 2 to 4 As shown, the wear-resistant detection assembly 4 includes a reciprocating telescopic rod 41, a friction rod 42, a friction block 43, a support, a pressure block 46, a gear 47, a swivel column 48 and a conversion member. The reciprocating telescopic rod 41 is fixedly mounted on the extended end of the height lifting rod 3. Two symmetrically arranged friction rods 42 are fixedly mounted on the end of the reciprocating telescopic rod 41. The friction rod 42 is connected to the friction block 43 by sliding up and down inside. A support member is arranged on the side of the friction block 43. The support member includes a pressure plate 44 and a support spring 45. The pressure plate 44 is fixedly mounted on the end of the friction block 43. The pressure plate 44 slides up and down inside the friction rod 42. The bottom of the pressure plate 44 is elastically connected to the friction rod 42. The friction block 43 is supported by the pressure plate 44 and the support spring 45 to control its height.

[0029] The friction rod 42 is reciprocated by extending and retracting the height lifting rod 3 to test the wear resistance of the thermal transfer film. The top of the friction testing body 1 is provided with a wrinkle flattening component 5 for placing the thermal transfer film, and the bottom of the friction block 43 is in contact with the thermal transfer film.

[0030] The inside of the friction rod 42 is slidably connected to a pressure block 46, a plurality of friction blocks 43 are provided, and a friction layer of different materials is fixedly installed at the bottom of each friction block 43, and each friction block 43 has a different length. The pressure block 46 is located directly above one of the friction blocks 43, and the height of the friction block 43 is lower than that of the other friction blocks 43. The top of the friction block 43 is provided with an inclined surface, and the bottom of the pressure block 46 is provided with symmetrically arranged inclined surfaces, and the inclination angle of the inclined surface of the pressure block 46 is the same as the inclination angle of the inclined surface of the friction block 43.

[0031] 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 of 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 switched to simulate a variety of thermal transfer film application scenarios.

[0032] The friction rod 42 is internally connected to a gear 47, and a swivel 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 swivel post 48 contacts the pressure block 46. A symmetrically arranged vertical plate is fixedly installed on the top of the pressure block 46. The swivel 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.

[0033] like Figure 5 and Figure 6 As shown, the conversion member includes a swivel 49, a rotating plate 410 and a toggle plate 411. The top of the swivel 49 is rotatably connected to the friction rod 42. The rotating plate 410 is fixedly installed on the outer arc surface of the swivel 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 swivel 49 and the gear 47.

[0034] When the inspection of one type of friction layer friction thermal 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, so that the rotating ring 49 and the gear 47 rotate. 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 supporting spring 45, so there is always only one friction block 43 in contact with the thermal transfer film.

[0035] 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 friction layers of different materials are 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 is different under the downward pressure of the pressure block 46, 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. Example 2

[0036] 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, which are distributed in a ring at equal angles 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 clamped with the positioning clip 62.

[0037] 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 causes 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.

[0038] An elastic sheet 64 is fixedly installed inside the swivel 49, and the elastic sheet 64 is meshingly connected to the gear 47. A plurality of elastic sheets 64 are arranged, 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 for resetting the swivel 49 and the rotating plate 410.

[0039] When the rotating ring 49 rotates counterclockwise, the blocking block 65 abuts against the side of the elastic sheet 64, and the rotating ring 49 rotates synchronously with the gear 47; when the rotating ring 49 rotates clockwise, the elastic sheet 64 bends and separates from the blocking block 65, and the gear 47 does not rotate synchronously with the rotating ring 49. This prevents the rotating plate 410 from being moved by the toggle plate 411 and the height lifting rod 3 extending to perform the second type of friction, causing the rotating plate 410 to move and be toggle the toggle plate 411 again, causing the gear 47 to rotate, and the friction type cannot be switched. The positioning hole 61 is engaged with the positioning clip 62 as a rotation resistance of the gear 47.

[0040] 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 a rotation resistance for the gear 47, thereby preventing the elastic sheet 64 from driving the gear 47 to rotate when the swivel 49 rotates clockwise. Example 3

[0041] Based on the above-mentioned 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 bottom plate 51, a pressing plate 52 and a friction track 53. The bottom plate 51 is fixedly installed on the top of the friction detection body 1. A thermal transfer film is placed on the top of the bottom plate 51. The top of the bottom plate 51 covers the pressing plate 52. The bottom plate 51 and the pressing plate 52 sandwich the thermal transfer film. Two symmetrically arranged friction tracks 53 are provided on the top of the pressing plate 52. The friction rod 42 extends from the friction track 53 to the bottom of the pressing plate 52 and contacts the thermal transfer film. The toggle plate 411 is fixedly installed on the friction track 53. The thermal transfer film is fixed by the cooperation of the bottom plate 51 and the pressing plate 52 to prevent the thermal transfer film from moving when the friction block 43 rubs the thermal transfer film, and the wear resistance cannot be normally detected.

[0042] like Figure 8 and Fig. 9 As shown, the pressure plate 52 is internally rotatably connected to two symmetrically arranged rotating rods 54, the ends of the rotating rods 54 are bent, the sides of the rotating rods 54 are rotatably connected to the squaring bars 55, the internal squaring bars 55 are rotatably connected to the coating roller 56, a torque spring is elastically connected between the rotating rods 54 and the pressure plate 52, the squaring bars 55 and the coating roller 56 are both in contact with the thermal transfer film, and a receiving cavity for accommodating the rotating rods 54 and the squaring bars 55 is provided on the top inner wall of the bottom plate 51.

[0043] Since the end of the rotating rod 54 is bent, when the pressing plate 52 is lowered, the rotating rod 54 is subjected to a horizontal force, and at this time, the squaring bar 55 moves along the thermal transfer film, and the folds on the thermal transfer film are flattened by the squaring bar 55 to prevent the folds from affecting the friction detection. After the bottom plate 51 and the pressing plate 52 are combined, the bottom plate 51 and the pressing plate 52 completely clamp and fix the thermal transfer film to prevent the friction detection from driving the thermal transfer film to move, and after the bottom plate 51 and the pressing plate 52 are combined, the receiving cavity receives the rotating rod 54 and the squaring bar 55.

[0044] A diffusion cotton strip 57 in contact with the smear roller 56 is fixedly installed inside the smearing strip 55, and an alcohol bin 58 is provided inside the pressing plate 52. The diffusion cotton strip 57 extends along the smearing strip 55 and the rotating rod 54 into the alcohol bin 58. The smearing roller 56 moves along the thermal transfer film, and the diffusion cotton strip 57 absorbs alcohol and diffuses it on its surface. The smearing 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, the alcohol is used together with the smearing roller 56 to clean the attachments on the surface of the thermal transfer film.

[0045] 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 is moved along the thermal transfer film. 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 prevent the presence of attachments from causing changes in the detection friction and causing detection errors.

[0046] The above specific embodiments are only 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 can make various alternative improvements and combinations to the above specific embodiments.
