DETAILED DESCRIPTION

[0034] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification. Since the embodiment of the utility model is an improvement based on the background technology, if there is any missing content below, it can be supplemented from the background technology and the technical solution disclosed in CN212095681U.

[0035] As a specific embodiment, the double-beam synchronous transmission mechanism of the embodiment of the utility model includes a grinding device 1, which is used to be arranged above the grinding and conveying device 2. The grinding device 1 includes a grinding piece 11, and the grinding piece 11 includes a first grinding piece 111, a second grinding piece 112, a third grinding piece 113, and a fourth grinding piece 114, which are respectively used to grind the four sides of the rectangular glass plate.

[0036] Usually, an input device 8 and an output device 9 are respectively provided at both ends of the grinding and conveying device 2. A plurality of power rollers 21 are provided on the grinding and conveying device 2, and a clearance gap 211 for avoiding the grinding piece 11 is directly provided between two adjacent power rollers 21. The input device 8 and the output device 9 are respectively used to input the glass plate to be ground and output the glass plate after grinding.

[0037] The grinding device 1 further includes a beam moving device 125 , a driving pulley 1251 , a connecting structure 127 and two beam assemblies 12 .

[0038] One of the two beam assemblies 12 includes a first beam 121, a second beam 122 and a connecting beam 1241; the first beam 121 is parallel to the second beam 122 and perpendicular to the connecting beam 1241, and both ends of the connecting beam 1241 and the second beam 122 are fixedly connected to the connecting beam 1241 respectively.

[0039] The other of the two beam assemblies 12 includes a second beam 122 , a third beam 123 and a second connecting beam 1242 ; the second beam 122 is parallel to the third beam 123 and perpendicular to the second connecting beam 1242 ; both ends of the second beam 122 and both ends of the third beam 123 are fixedly connected to the second connecting beam 1242 , respectively.

[0040] It is easy to understand that the two cross beam assemblies 12 are both rectangular frame-shaped as a whole, and are both provided with a second cross beam 122; the first connecting beam 1241 and the second connecting beam 1242 are both fixedly provided with supporting columns 129, so that the first connecting beam 1241 and the second connecting beam 1242 are fixed above the grinding conveying device 2 through the supporting columns 129. Accordingly, the two cross beam assemblies 12 are completely identical and rotationally symmetrical about themselves, so when producing the cross beam assemblies 12, it is only necessary to produce a plurality of cross beam assemblies 12 of the same specification (i.e., any one of the two cross beam assemblies 12), and then one of the cross beam assemblies 12 can be rotated 180 degrees to cooperate with the other cross beam assembly 12, so it is convenient to mass produce the cross beam assemblies 12 and help reduce costs.

[0041] Similar to the prior art, the first grinding member 111 can move as a whole with the first beam 121 ; the third grinding member 113 is fixed relative to the beam assembly 12 and serves as a positioning reference; and the fourth grinding member 114 can move as a whole along the third beam 123 .

[0042] The beam moving device 125 is an annular belt and is respectively arranged on the two beam assemblies 12, for example, the beam moving device 125 is a synchronous belt, etc.; the beam moving device 125 is mounted on the driving pulley 1251, and at least one of the driving pulleys 1251 has rotational power, for example, it has rotational power driven by the beam moving motor 126.

[0043] The driving pulleys 1251 of the two cross beam assemblies 12 are connected via a connecting structure 127 so that the cross beam moving devices 125 of the two cross beam assemblies 12 move synchronously.

[0044] The second polishing member 112 is detachably connected to the beam moving devices 125 of the two second beams 122 , so that it can move linearly along the second beams 122 .

[0045] The working principle is that, in the factory production stage, the first grinding piece 111, the second grinding piece 112, the third grinding piece 113, the fourth grinding piece 114, and the two cross beam assemblies 12 are assembled and loaded into containers for transportation. It should be noted that since the grinding conveying device 2, the input device 8, and the delivery device 9 are all relatively mature power roller structures, it is relatively easy to adjust their sizes according to the size of the container.

[0046] After the container is transported to the site of use, the first polishing piece 111, the second polishing piece 112, the third polishing piece 113, the fourth polishing piece 114, the two beam assemblies 12, etc. are taken out of the container, and simple module assembly can be performed at the site of use to complete the assembly of the glass edge grinding machine; after the assembly is completed, the second polishing piece 112 is synchronously driven by the two beam moving devices 125 to move, which can ensure the movement accuracy of the second polishing piece 112.

[0047] In summary, the double-beam synchronous transmission mechanism of the embodiment of the utility model can not only realize the miniaturization of the beam assembly 12 so as to be transported through a container, but also ensure the movement accuracy of the second grinding member 112.

[0048] As one of the specific implementations, the connection structure 127 also includes a coupling 1272; the connecting shaft 1271 includes two half shafts (not shown in the drawings), and one end of the two half shafts is detachably connected to the driving pulleys 1251 of the two beam assemblies 12, for example, the half shafts and the driving pulleys 1251 are both provided with keyways, and a semicircular key or other key is embedded in the keyway to realize the detachable connection between the half shaft and the driving pulley 1251. The other ends of the two half shafts are connected by a coupling 1272. During transportation, the two half shafts are separated from the driving pulleys 1251 of the two beam assemblies 12, so that the half shafts will not protrude from the beam assembly 12 during transportation and be subjected to a large impact force, thereby ensuring the accuracy of the connecting shaft 1271. For example, the coupling 1272 can be a rubber elastomer coupling of the LK19 series of Guangzhou Linke Automation Equipment Co., Ltd. During assembly, the two cross beam components 12 will inevitably produce assembly errors. The rubber elastic coupling can absorb the assembly errors and ensure the transmission between the two half shafts.

[0049] As one of the specific implementations, the two cross beam assemblies 12 both include an inner guard beam 1243 parallel to the second cross beam 122 . It is easy to understand that the inner guard beams 1243 of the two cross beam assemblies 12 are adjacent; the half shafts pass through the inner guard beams 1243 respectively.

[0050] As one of the specific implementations, the inner guard beams 1243 are each provided with a support bearing 1273, and the middle of the half shaft passes through the support bearing 1273, so that the half shafts pass through the inner guard beams 1243, respectively, which can ensure that the half shafts rotate smoothly when in use.

[0051] As one of the specific implementations, Figure 5 As shown by the dotted line, the second grinding member 112 includes a base, and the bottom ends of the second cross beam 122 and the inner beam 1243 of the two cross beam assemblies 12 are fixedly provided with linear slide rails (a total of four linear slide rails), and the linear slider 128 of the base is detachably fixedly connected to the base. While ensuring the movement accuracy of the second grinding member 112, the second grinding member 112 can be separated from the cross beam assembly 12 for easy transportation.

[0052] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0053] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0054] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0055] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the relevant standards of dimensional tolerance.
