Detailed implementation mode

[0025] The present utility model will be further described below with reference to the accompanying drawings:

[0026] The nouns involved in the paragraphs for detailed description are only for the convenience of those skilled in the art to understand the technical solutions recorded in this application according to the visual directions shown in the accompanying drawings. Unless otherwise clearly stipulated and defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] As Figures 1 to 4As shown, a wear resistance testing device for PVC wood grain plastic film includes a housing 100, a friction assembly 200, and a material laying table 300. A groove 110 is provided on one side of the housing 100, and a material laying table 300 is installed at the edge 111 of the groove 110. Below the material laying table 300 is a waste bin 112. A plurality of friction assemblies 200 are also installed at the edge 111 of the groove 110, and the friction assemblies 200 are hinged to the edge 111 of the groove 110. Among them, a self-tightening structure 210 is installed at one end of the friction assembly 200.

[0028] Optionally, an operation panel 101 adapted to the friction assembly 200 is hinged on the outer side wall of the housing 100. In this way, parameters such as the rotation speed, cycle times, cycle intervals, and start or stop of the friction assembly 200 can be set through the provided operation panel 101. Compared with the traditional mechanical knob setting method, the operation panel 101 not only makes the parameter setting more accurate, but also makes the operating parameters of the friction assembly 200 more intuitively reflected.

[0029] As Figure 3 and Figure 4 As shown, the friction assembly 200 includes a first side plate 201, a second side plate 202, a driving assembly 220, a tensioning wheel 203, and a friction belt 204. The first side plate 201 and the second side plate 202 are arranged in parallel. The driving assembly 220 is installed at one end of the first side plate 201 and the second side plate 202 and is located between them, and both ends of the driving assembly 220 are rotatably connected to the first side plate 201 and the second side plate 202 respectively. The tensioning wheel 203 is installed at the end of the first side plate 201 and the second side plate 202 away from the driving machine 221 and is rotatably connected to both of them. One side of the friction belt 204 is bonded to the driving assembly 220 and / or the tensioning wheel 203, wrapping the driving assembly 220 and the tensioning wheel 203 inside and rotating with the driving assembly 220 and the tensioning wheel 203. In this way, after the friction belt 204 is connected to the driving assembly 220 and the tensioning wheel 203, it can be self-adjusted through the tensioning wheel 203 to ensure that the friction belt 204 is always in a tight state, so that the friction belt 204 can uniformly frictionally contact the material to be detected.

[0030] Optionally, hinge ears 2011 are provided at one end of the first side plate 201 and the second side plate 202. In this way, the first side plate 201 and the second side plate 202 can be hinged to the housing 100 through the hinge ears 2011 to complete the opening or closing of the friction assembly 200.

[0031] Optionally, a lifting rod 2012 is provided at the end of the first side plate 201 and the second side plate 202 away from the hinge ears 2011. In this way, a force application point can be provided for the opening and closing of the friction assembly 200 through the lifting rod 2012, enabling it to easily complete the opening or closing action.

[0032] Optionally, the friction belt 204 has a cuttable structure. In this way, the two ends of the cuttable friction belt 204 are cross-sections, which can easily rub against the gap of the friction assembly 200 and be connected to the drive assembly 220 and the tensioning wheel 203. Thus, the replacement of the friction belt 204 can be completed without disassembling the friction assembly 200. The replacement efficiency of the friction belt 204 is effectively improved.

[0033] Optionally, connecting belts 208 are installed at both ends of the friction belt 204. In this way, the cut friction belt 204 can connect the head and tail of the friction belt 204 into a circular whole through the connecting belts 208, so as to rotate reciprocally between the drive assembly 220 and the tensioning wheel 203.

[0034] Optionally, a plurality of grooves 209 adapted to the connecting belts 208 are provided on the surface of the tensioning wheel 203. In this way, during the reciprocating rotation of the friction belt 204, the connecting belt 208 for connecting the head and tail of the friction belt 204 can be embedded in the grooves 209, avoiding the protrusion when the connecting belt 208 rotates to the positions of the drive assembly 220 and the tensioning wheel 203. Thus, it is ensured that the friction belt 204 can contact the detection surface evenly.

[0035] As Figure 4 and 5 shown, the drive assembly 220 includes a drive machine 221, a first drive wheel 222, a second drive wheel 223, and a connection bracket 224. The first drive wheel 222 is installed at one end of the drive machine 221, the second drive wheel 223 is installed at the other end of the drive machine 221, and the ends of the first drive wheel 222 and the second drive wheel 223 away from the drive machine 221 are respectively rotatably connected to the first side plate 201 and the second side plate 202; the connection bracket 224 is fixedly connected to the first side plate 201 and the second side plate 202, extends towards the direction of the drive machine 221, and is fixedly connected to the outer side wall of the drive machine 221. In this way, the drive machine 221 has two synchronous power output shafts, which can drive the first drive wheel 222 and the second drive wheel 223 to rotate synchronously to ensure that the friction belt 204 can be driven to rotate smoothly. In addition, the connection bracket 224 for fixing the drive machine 221 is fixedly connected to the first side plate 201 and the second side plate 202 at both ends, which not only enhances the connection stability between the first side plate 201 and the second side plate 202, but also improves the operation stability of the drive machine 221.

[0036] As Figure 4As shown, hook surface velvet 205 is provided on the outer walls of the first driving wheel 222, the second driving wheel 223, and the tensioning wheel 203, and is adaptively connected to one side of the friction belt 204. In this way, through the hook surface velvet 205 on the outer side walls of the first driving wheel 222, the second driving wheel 223, and the tensioning wheel 203, the friction force with the friction belt 204 can be increased, and the situation of slipping between the friction belt 204 is avoided. Thus, not only the running stability of the friction belt 204 is improved, but also the accuracy of detection is improved.

[0037] As Figure 4 shown, one side of the friction belt 204 is a flocked surface 206 adapted to the hook surface velvet 205, and the other side is a friction surface 207. In this way, the surface of the flocked surface 206 is composed of several fluff. When the flocked surface 206 contacts the hook surface velvet 205, the hook surface velvet 205 will randomly hook out the fluff on the surface of the flocked surface 206, so that the two play a role of connecting with each other. As the friction belt 204 rotates continuously, the hook surface velvet 205 will be separated from the flocked surface 206 under the rotation and pulling of the driving machine 221, so that the connection between the two is released.

[0038] As Figures 6 to 9 shown, the self-tensioning structure 210 includes a through groove 211, a sliding groove 212, a sliding block 213, a spring groove 214, and a tensioning spring 215. The through groove 211 is provided at one end of the first side plate 201 and the second side plate 202 away from the driving assembly 220; a spring groove 214 is drilled on the side wall of the through groove 211 facing the driving machine 221, and a tensioning spring 215 is embedded in the spring groove 214; a plurality of sliding grooves 212 are also provided in the through groove 211, and the sliding grooves 212 are arranged in parallel in the through groove 211; the sliding block 213 is movably connected to the sliding groove 212 and abuts against the tensioning spring 215. In this way, when both ends of the tensioning wheel 203 are connected to the sliding blocks 213 in the first side plate 201 and the second side plate 202 respectively, the two connected sliding blocks 213 can be driven to move synchronously. At the same time, when the tensioning wheel 203 is connected to the friction belt 204, under the cooperation of the sliding block 213 and the tensioning spring 215, the sliding block 213 can be pushed in the direction away from the tensioning spring 215. Thus, it is ensured that the friction belt 204 connected to the tensioning wheel 203 is in a tight state during use, effectively improving the accuracy of friction detection.

[0039] As Figure 1 and Figure 2As shown, the laying table 300 further includes a plurality of fixing plates 310, and the fixing plates 310 are respectively arranged on the outer side wall of the housing 100 and are on the same straight line as the laying table 300. In this way, the material to be detected is laid flat on the laying table 300, and its two ends respectively extend to the positions of the fixing plates 310 and are fixed by the fixing plates 310. In this way, it can be ensured that the material to be detected is not easily displaced or separated during the detection process. Thus, the stability of the detection work is effectively improved.

[0040] As Figure 1 and Figure 2 As shown, the waste bin 112 is communicated with the mouth edge 111 of the groove 110, and a pull-out tray 113 is embedded in the waste bin 112, and one end of the pull-out tray 113 protrudes outside the housing 100. In this way, the debris generated when the friction belt 204 rubs against the detection material can be concentrated and fall into the pull-out tray 113 embedded in the waste bin 112 under the drive of the friction belt 204. So as to facilitate the subsequent centralized treatment of the debris and effectively reduce the pollution of the debris to the surrounding environment.

[0041] Finally, although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
