[0024] Embodiment, a filling and capping machine tightening screening device, structure reference Figure 1

[0025] The device is arranged on an existing filling and capping machine, the filling and capping machine is connected with a conveying belt 1, the conveying belt 1 comprises inner and outer baffles and a plurality of support frames; and the device further comprises a packaging bottle; the standing packaging bottle can be transported with the conveying belt 1.

[0026] The device comprises a linear section and an arc section connected with the linear section on the conveying belt 1; a blocking rod 2 is arranged on the upper part of the linear section, and a screening device is arranged on the arc section; the screening device comprises a rejection opening 3 formed on the outer baffle of the arc section, and a guide tab 4 is arranged at the position corresponding to the inner baffle of the arc section; the guide tab 4 is arranged in a bent manner and comprises a guide front section and a support rear section; the guide front section is arranged in a direction towards the rejection opening 3; the height of the rejection opening 3 is smaller than the height of the packaging bottle and larger than the width of the packaging bottle, and the width of the rejection opening 3 is larger than the height of the packaging bottle.

[0027] A bottle receiving net bag is arranged below the rejection opening 3; the bottle receiving net bag can collect the packaging bottles from the rejection opening 3.

[0028] The bottle receiving net bag is bound to the support frame; the binding arrangement facilitates the installation, use and disassembly of the bottle receiving net bag.

[0029] The blocking rod 2 is a rod body structure arranged in a horizontal manner and having a rectangular cross section; compared with a conventional round rod, the rectangular rod body has a better blocking effect on the packaging bottle and can successfully knock down the packaging bottles with an excessive height.

[0030] Two telescopic support rods 5 are arranged at the two ends of the blocking rod 2; the telescopic support rod 5 is formed by sleeving two pipe bodies with different diameters, a fastening bolt 6 is arranged on the outer side of the pipe body with a larger diameter, and the pipe body with a larger diameter is connected with the support frame; through the arrangement of the telescopic support rod 5, the height of the blocking rod 2 can be adjusted to adapt to packaging bottles with different height specifications; specifically, the height of the telescopic support rod 5 is adjusted by tightening or loosening the fastening bolt 6 and pulling out the pipe body with a smaller diameter.

[0031] ​The rear section of the support is fixed to the inner baffle with bolts. Installing the support at the rear section avoids leaving any mounting parts on the front guide section, thus preventing these parts from affecting the movement of the bottle along the front guide section or even scratching the bottle.

[0032] The working principle of this device is as follows: After the filling and capping machine completes the tightening of the bottle caps, the upright bottles are transported in an orderly manner on conveyor belt 1. When the bottle caps are fully tightened, the packaging is considered qualified. At this time, there is a qualified bottle height. Bottles with a height higher than this are considered unqualified. Adjust the baffle 2 to the height of the qualified packaging bottle. When the packaging bottle moves with the conveyor belt 1 and passes the baffle 2, the qualified packaging bottle can pass smoothly under the baffle 2, while the unqualified packaging bottle with an untight cap or not reaching the specified height will touch the baffle 2, thus being knocked over and lying on the conveyor belt 1. The conveyor belt 1 continues to transport, and because the height of the rejection port 3 is less than the height of the qualified packaging bottle, the standing qualified packaging bottle will not fall out of the rejection port 3; while the unqualified packaging bottle that has been knocked over on the conveyor belt 1 is guided by the guide plate 4 and will move towards the rejection port 3. Because the height of the rejection port 3 is greater than the width of the packaging bottle and the width of the rejection port 3 is greater than the height of the packaging bottle, the fallen unqualified packaging bottle will fall out of the rejection port 3, thus realizing the rejection of the unqualified packaging bottle. The fallen unqualified packaging bottle can be collected in the bottle receiving net bag for further manual processing.

[0033] When the above device was implemented on the production line, it was found that when the height of the bottle after the cap was screwed on was higher than 151mm, it was considered a defective product. Therefore, the height of the baffle 2 was adjusted to 151mm. The bend of the conveyor belt 1.2m downstream of the baffle 2 was modified. A guide plate 4 with a bend of about 130 degrees was added to the inner conveyor belt baffle. At the same time, the outer baffle of the conveyor belt was slotted and hollowed out to form a rejection port 3, leaving space for the defective bottle to roll off. A bottle-catching net was tied to the rejection port 3.

[0034] Implementation results: After the modification, when the non-conforming packaging bottles pass through the baffle 2, they are knocked over. When the knocked-over packaging bottles pass through the guide plate 4, they are guided and roll down from the rejection port 3 into the collection net bag. This realizes the screening of non-conforming products, so there is no need to arrange employees to observe and screen for a long time, which reduces the risk of non-conforming products entering the market, greatly improves production efficiency, and saves labor costs.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
