Description

TECHNICAL FIELD

[0001] The utility model relates to a packaging line production equipment, concretely is a kind of quick conveying online dispensing system. BACKGROUND

[0002] With the development of modern production technology, dispensing technology has been widely used in packaging industry, especially in the sealing treatment of carton packaging. In order to ensure the sealing effect of carton, stability and improve production efficiency, hot melt adhesive is adopted by the majority of enterprises as a kind of fast curing, reliable sealing material.

[0003] In order to ensure the accuracy of dispensing, the traditional dispensing system often uses bottom supporting belt to convey carton. In theory, such design ensures the stability of carton in conveying process, and helps glue to drop accurately to the target position of carton. However, in actual operation, the system has many problems.

[0004] Firstly, when the dispensing machine is running at high speed, especially in continuous operation, sometimes the position of glue dropping will appear error due to various factors, such as slight deviation of glue gun, unstable glue flow, slight difference of carton size, etc. These misdropped glues may fall on the bottom supporting belt. Once the glue drops on the belt, it will quickly solidify and firmly adhere to the surface of the belt.

[0005] Such glue residue not only leads to waste of glue, but also the glue residue on the belt will be more and more with the continuous operation of production line. This not only affects the smooth running of the belt, increases the friction and instability of carton conveying, but also may cause damage or premature wear of the belt, greatly shortens its service life.

[0006] Moreover, when other cartons pass through these glue contaminated parts, glue will be transferred to carton, causing product appearance stain, and further affecting product neatness and sales value. In order to remove these glue stains, production line needs to be frequently stopped for cleaning and maintenance, which not only increases production cost, but also reduces production efficiency.

[0007] In summary, although the traditional dispensing system meets the production demand to some extent, its obvious defects also limit the improvement of production efficiency and product quality. Therefore, it is particularly important to design a new dispensing system which can avoid glue misdropping and pollute the conveying belt. INVENTION CONTENTS

[0035] Working principle: The core technology of the rapid conveying online dispensing system is its unique clamping feeding mechanism and conveying method, which optimizes the dispensing process and avoids common problems. The working principle is described in detail as follows:

[0036] 1. Operation of the packaging box feeding mechanism: In the initial stage of production start-up, the packaging box to be dispensed is placed on the feeding conveyor belt. As the conveyor belt is driven, the packaging box gradually advances at a set speed and direction. At the same time, the box cover of the packaging box is clamped and positioned by the box cover guide-in mechanism. This is achieved by utilizing the guide-in gap between the first guide-in rod and the second guide-in rod, ensuring that the box cover is in the predetermined position before entering the dispensing area. Avoiding the influence of the box cover on dispensing.

[0037] 2. Operation of the packaging box dispensing mechanism: When the packaging box enters the second main frame area, the clamping feeding mechanism begins to work. Unlike traditional conveyor belts, the clamping feeding mechanism carries the bottom of the packaging box through the bottom support wheel on it, and the clamping feeding belt contacts the side wall of the packaging box, ensuring the stability of the packaging box during conveying. The key design here is that due to the clamping method, the bottom of the packaging box is actually in a hollow state. This means that during dispensing, even if the dispensing gun drips, the dripping glue will not contact the conveyor belt, but will directly fall into the specially designed collection area at the bottom of the equipment. This design avoids the common problem in traditional technology, i.e. the pollution and subsequent cleaning difficulty caused by glue dripping onto the conveyor belt. When the packaging box passes through the dispensing gun, the hot melt glue is accurately dropped into the packaging box, which ensures accurate application of the glue and avoids misdropping. In order to adapt to packaging boxes of different widths and adjust the glue dropping position, an adjustment mechanism is provided between the second main frame 4 and the clamping feeding mechanism 5, which drives the clamping feeding mechanism 5 to displace on the guide shaft 43. The adjustment mechanism is a screw rod 44 rotatably installed on the second main frame 4, and a screw nut 45 is screwed on the screw rod 44 and connected with the clamping feeding mechanism 5. When adjusting, the screw rod is driven to rotate by a hand wheel, and the clamping feeding mechanism is driven to displace by the screw nut, so as to adjust the glue dropping position and match the size of the packaging box.

[0038] 3. Operation of the packaging box shaping and discharging mechanism: After dispensing is completed, the packaging box continues to move to the discharging area. Here, they are placed on the discharging conveyor belt and driven by the third main frame. To ensure the integrity of the packaging box during cooling and glue curing, the box cover guide-out mechanism clamps and positions the box cover of the packaging box. The positioning pressure rod further ensures that the box cover is tightly attached during the entire discharging process, avoiding any unnecessary movement or displacement. In summary, the rapid conveying online dispensing system effectively avoids the problem of glue misdropping onto the conveyor belt through its unique clamping feeding mechanism and other design innovations, improves production efficiency, and reduces the need for maintenance and cleaning.
