Description

Technical Field

[0001] The present application relates to the technical field of candy production and packaging, and in particular to a sealing mechanism for packaging bulk candies in a barrel package. Background Art

[0002] The main raw materials of candy include sugar, syrup or sweetener, etc., which are then processed through a series of processes. These processing steps may include mixing, pressing, molding, coloring, drying, etc. to make candies of different shapes, colors and flavors. There are many types of candy, including hard candy, soft candy, chocolate candy, lollipops, marshmallows, etc.

[0003] The current publication number is CN211766812U A Chinese patent discloses a novel quantitative device for a candy particle mixture, comprising a base, a protective frame is provided on the upper side of the base, a material barrel is fixedly installed on the upper side of the protective frame, a first motor is fixedly installed on the upper side of the material barrel, a reducer is fixedly installed on the output end of the first motor, a stirring shaft is connected to the lower side of the reducer, a stirring rod is fixedly installed on the surface of the stirring shaft, a discharge pipe is fixedly installed on the lower side of the material barrel, a first hopper is fixedly installed on the top of the material barrel, a baffle is provided on the top of the protective frame, a rack is fixedly installed on the lower side of the baffle, a slider is fixedly installed on the upper side of the baffle, a slide groove is provided on the top of the protective frame, and the slider is slidably connected to the slide groove.

[0004] The novel quantitative device for candy granule mixture drives the incomplete gear to rotate through the second motor. When the teeth of the incomplete gear mesh with the rack, the rack and the baffle are driven to move to the left. The baffle drives the connecting plate to move to the left. The connecting plate stretches the spring. The left end of the baffle is stuck in the groove provided on the side wall of the discharge pipe to achieve the blocking of the discharge pipe. When the teeth of the incomplete gear completely rotate over the rack, the stretched spring drives the connecting plate to move to the right. At the same time, the connecting plate drives the baffle to move to the right. The discharge pipe opens and the candy mixture falls. The above arrangement realizes the quantitative delivery of the candy mixture. It only needs to calculate the unit volume weight of the candy mixture and adjust the speed of the incomplete gear to realize the quantitative delivery of candy mixtures of different masses, thereby improving the practicality of the device. However, the novel quantitative device for candy granule mixture still has some disadvantages, such as: after the quantitative candy is loaded into the packaging box, the packaging cover is manually covered on the packaging box. The efficiency of manually covering the packaging cover is slow, which affects the efficiency of the overall packaging of the candy and needs to be improved. Utility Model Content

[0007] By adopting the above technical solution, after the packaging barrel on the conveyor belt is filled with quantitative candies, the conveyor belt drives the packaging barrel to move in the direction close to the installation column, so that the packaging barrel filled with quantitative candies moves to the corresponding position. Multiple packaging covers are placed in the installation groove along the length direction of the installation column, and the packaging cover closest to the base corresponds to the channel.

The moving component moves the packaging cover pushed out of the channel to the packaging barrel located on the conveyor belt, so that the packaging cover and the packaging barrel have an interference fit, and the packaging cover and the packaging barrel are automatically installed, which improves the overall packaging efficiency of the candies. After the packaging cover closest to the base is pushed out of the channel, the first driving member drives the push plate to move to the original position, and the remaining packaging covers in the installation groove are moved in the direction close to the channel under the influence of gravity, so that another packaging cover corresponds to the channel, which is convenient for the packaging covers in the installation groove to be pushed out of the channel in sequence.

[0012] Optionally, a support plate is slidably connected in the installation groove, and the base is connected to a fifth driving member for driving the support plate to slide in a vertical direction.

[0013] By adopting the above technical solution, the fifth driving member drives the support plate to rise, so that multiple packaging covers can be placed on the support plate. The fifth driving member drives the support plate to fall, so that the packaging cover closest to the support plate corresponds to the channel.

[0014] Optionally, the base is connected to a positioning plate for abutting against the packaging cover, and the channel is located between the mounting groove and the positioning plate.

[0015] By adopting the above technical solution, after the packaging cover is pushed out of the channel by the push plate, until the packaging cover abuts against the positioning plate, the positioning plate moves the packaging cover to a corresponding position, making it convenient for the moving assembly to move the packaging cover to the conveyor belt.

[0016] Optionally, the base is connected to two limit plates, the base and the two limit plates enclose a slide groove for slidingly cooperating with the packaging cover, and the two limit plates are located between the base and the positioning plate.

[0017] By adopting the above technical solution, the packaging cover slides between the two limiting plates, and the sliding cooperation between the packaging cover and the slide groove guides and limits the sliding of the packaging cover, thereby improving the sliding stability of the packaging cover and moving the packaging cover to the corresponding position.

[0018] Optionally, the limiting plate is connected to a cover plate for covering the slide groove.

[0019] By adopting the above technical solution, the cover plate restricts the sliding of the packaging cover, thereby preventing the packaging cover from falling out of the sliding groove during the sliding process.

[0023] By adopting the above technical solution, the eighth driving member drives the incomplete gear to rotate, and when the incomplete gear is engaged with the driven gear, the driven gear is driven to rotate, that is, the conveyor belt rotates. When the incomplete gear is separated from the driven gear, the conveyor belt stops rotating, which makes it easier to cover the packaging cover on the packaging barrel.

[0024] Optionally, the conveyor belt is connected to a plurality of rubber blocks, and the rubber blocks are provided with placement grooves for cooperating with packaging barrels.

[0025] By adopting the above technical solution, the packaging barrel is placed in the placement groove, and the outer peripheral surface of the packaging barrel is in contact with the inner wall of the placement groove. The inner wall of the placement groove restricts the movement of the packaging barrel, thereby improving the stability of the packaging barrel placed on the conveyor belt.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The push plate abuts against the packaging cover and pushes the packaging cover out of the channel.
