[0001] The utility model relates to the technical field of food package weight detection, in particular to food package weight detection equipment. Background Art

[0002] Food packaging is an important link in industrial production, indicating that the product enters the final packaging process. Products of the same specifications have relatively the same packaging weight, but inevitably there will be products with large weight errors during the packaging process. Therefore, during the production and processing, it is necessary to weigh the packaged food. In the prior art, online weighing machines are mostly used to perform batch continuous weighing and testing of food packaging, and at the same time as the weighing and testing, cylinders are used to synchronously return food packaging with unqualified weight.

[0003] Although the prior art can facilitate mobile continuous weighing and testing of food packaging through online weighing machines, it is inevitable that there are still some shortcomings in its actual use. For example, the device lacks a quick centering mechanism, which makes it inconvenient to weigh the packaged products in the center and to cut them in an orderly manner in the center. In order to avoid such problems, a food packaging weight detection device is proposed to solve the existing problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a food packaging weight detection device, which solves the problem that the device lacks a rapid centering mechanism, resulting in inconvenience in centering weighing and centering regular feeding of packaged products.

[0006] Preferably, a plurality of latch grooves are equidistantly formed on the surface of the limit rod, the front and rear sides of the online weighing machine are fixedly connected with threaded sleeves, and the internal threads of the threaded sleeves are connected with threaded pins matched with the latch grooves.

[0007] Preferably, both sides of the two center adjustment plates opposite to each other are fixedly connected with limit slide bars, and both sides of the front and rear sides of the online weighing machine are fixedly connected with sliding sleeves slidably matched with the limit slide bars.

[0008] Preferably, a mounting frame is fixedly connected to the top of the online weighing machine, and one side of the mounting frame is fixedly connected to the side of the driving motor through a bracket.

[0009] Preferably, the two cam protrusions are arranged in opposite directions. Beneficial Effects

[0010] The utility model provides a food packaging weight detection device. Compared with the existing technology, the utility model has the following beneficial effects: the utility model arranges a centering adjustment plate on the front and rear sides of the top of the online weighing machine, and arranges a U-shaped frame, a rotating shaft and a cam between the centering adjustment plate and the driving motor, so that the two centering adjustment plates can cooperate with each other through the above-mentioned driving to achieve the effect of quickly centering the packaged food, and secondly, a threaded pin and a pin slot are arranged between the limit rod and the online weighing machine, so that the centering adjustment plate can slide forward and backward and easily be controlled at a fixed point, so as to provide a more suitable replacement space when replacing cams with different convex point lengths later.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-4The utility model provides a technical solution: a food packaging weight detection device, including an online weighing machine 1, a centering adjustment plate 2 is slidably arranged on the front and rear sides of the top of the online weighing machine 1, two centering adjustment plates 2 are fixedly connected to the opposite sides of the two centering adjustment plates 2, and the heights of the two U-shaped frames 3 are staggered, a driving motor 4 is arranged on the top of the online weighing machine 1, a mounting frame 15 is fixedly connected to the top of the online weighing machine 1, and one side of the mounting frame 15 is fixedly connected to the side of the driving motor 4 through a bracket, the output shaft of the driving motor 4 is fixedly connected to a rotating shaft 5 through a coupling, and the top and bottom of the surface of the rotating shaft 5 are fixedly connected to a cam 6 used in conjunction with the U-shaped frame 3 by bolts. As a detailed explanation: the online weighing machine 1 is an online checkweigher, and its model is SCW.

[0018] As a detailed explanation: the front and rear sides of the online weighing machine 1 are fixedly connected to the limiting sleeve 7 through a bracket, the limiting sleeve 7 is internally slidably connected to the limiting rod 8, and a reset spring 9 is fixedly connected between the adjacent limiting rods 8 and the limiting sleeve 7, the opposite ends of the two limiting rods 8 are respectively fixedly connected to the opposite sides of the two center adjustment plates 2, the two cam 6 protrusions are set in opposite directions, the two sides of the opposite sides of the two center adjustment plates 2 are fixedly connected to the limiting slide bar 13, and the front and rear sides of the online weighing machine 1 are fixedly connected to the sliding sleeve 14 that is slidably adapted to the limiting slide bar 13.

[0019] Furthermore, in order to facilitate the subsequent replacement of the cam 6 and provide a suitable replacement space, a plurality of pin grooves 12 are equidistantly provided on the surface of the limit rod 8, and a threaded sleeve 10 is fixedly connected to the front and rear sides of the online weighing machine 1, and the internal thread of the threaded sleeve 10 is connected to a threaded pin 11 used in conjunction with the pin groove 12.

[0020] When in use, the operator places the packaged food between the two centering adjustment plates 2, and the conveying table located on the top of the online weighing machine 1 is moved for weighing. The driving motor 4 is started at the same time for conveying and weighing. The driving motor 4 drives the rotating shaft 5 and the cam 6 to rotate. The rotation of the two cams 6 will repeatedly squeeze the U-shaped frame 3, prompting the two U-shaped frames 3 to synchronously drive the centering adjustment plates 2 to move in the same and reverse directions. The synchronous reciprocating movement of the two centering adjustment plates 2 will adjust the packaged food on the conveying table of the online weighing machine 1 in the center.

[0021] If it is necessary to replace the cam 6 with a different convex point length to change the centering adjustment range of the centering adjustment plate 2 and the U-shaped frame 3, the operator first loosens the bolts between the rotating shaft 5 and the cam 6, and then drags the U-shaped frame 3 to move the U-shaped frame 3 away from the surface of the rotating shaft 5. The U-shaped frame 3 moves synchronously with the centering adjustment plate 2 as the medium to drive the limit rod 8 to extend out of the limit sleeve 7. When the moving distance of the U-shaped frame 3 is suitable for subsequent installation, the operator screws the threaded pin 11 to cause the threaded pin 11 to rise and engage the pin positioning with the pin groove 12 in the limit rod 8.
