Description

Technical Field

[0001] The utility model relates to the technical field of glue coating machines, in particular to a paperboard glue coating machine. Background Art

[0002] With the development of the times, people's demand for cardboard gluing is not limited to full coating and flat coating, but more sophisticated gluing requirements have emerged. Take the production of common honeycomb filled cardboard as an example: the cardboard needs to be intermittently coated with glue and then stretched to form honeycomb gaps.

[0003] Existing cardboard gluing machines often use a glue stick structure, which uses the glue stick to pick up glue and then smear it on the cardboard surface. Due to structural limitations, intermittent gluing cannot be performed, so glue sticks with special shapes are produced. The changes in the cylindrical shape of the special glue sticks are used to achieve the same gluing results as intermittent gluing. Although this method of using special sticks for special purposes has temporarily solved the problem, the extremely low utilization rate of the special glue sticks makes this method impossible to promote.

[0032] Combination Figures 1 to 6 As shown, the glue coating assembly 1 includes a glue nozzle 11 and a glue coating head 12, the glue nozzle 11 and the glue coating head 12 are integrally formed, the glue coating head 12 is composed of a horizontal plate and an inclined plate, and the width of the glue coating head 12 is equal to the width of the glue nozzle 11, the horizontal plate is connected to the main body of the glue nozzle 11, the inclined plate is located below the glue outlet of the glue nozzle 11, and anti-overflow protrusions 121 are provided on both sides of the inclined plate; a first fixing rod 2, the glue coating head 12 is evenly fixed on the first fixing rod 2 The gluing components 1 are fitted together, the width of the cardboard can be divided by the width of the gluing components 1, and the total width of the gluing components 1 on the first fixing rod 2 is the same as the width of the cardboard; each of the gluing components 1 works independently, and glue is delivered to the gluing head through a glue nozzle, and the glue is applied to an area of ​​a specified width through the gluing head. Through the cooperation of multiple uniform and independent gluing components, the gluing area can be planned, and refined gluing tasks such as intermittent gluing can be completed.

[0033] In some embodiments, in combination Figure 1 As shown, it also includes a second fixing rod 3, which is located parallel to the side of the first fixing rod 2, and the gluing component 1 is fixed on the second fixing rod 3. By adding the second fixing rod 3 to install a new gluing component 1 and cooperating with the gluing component 1 on the first fixing rod 2, more diverse gluing effects can be achieved, so that the cardboard gluing machine can be applied to more scenarios.

[0034] In some embodiments, in combination Figure 4As shown, the number of the gluing components 1 on the second fixed rod 3 is one less than the number of the gluing components 1 on the first fixed rod 2, and the gluing components 1 on the second fixed rod 3 and the gluing components 1 on the first fixed rod 2 are arranged alternately. By partially overlapping the gluing areas of the gluing components 1, the width of the gluing area can be controlled in time, thereby improving the applicability of the cardboard gluing machine.

[0035] In some embodiments, in combination Figure 5 , Figure 6 As shown, the number of the gluing components 1 on the second fixed rod 3 is 1, and the gluing components 1 on the second fixed rod 3 are fixedly connected to a driving motor 31, and the driving end of the driving motor 31 and the second fixed rod 3 are driven by gears and teeth. The driving end of the driving motor 31 is a gear, and the second fixed rod 3 is provided with teeth to mesh with it. The position of the gluing component 1 on the second fixed rod 3 can be controlled in real time by the driving motor 31, thereby increasing the gluing diversity of the cardboard gluing machine.

[0036] In some embodiments, in combination Figure 1 As shown, it also includes a hydraulic cylinder lifter 7, which is composed of a hydraulic cylinder and a fixed block. The driving end of the hydraulic cylinder is fixedly connected to the fixed block. The two sections of the first fixed rod 2 or the second fixed rod 3 on the fixed block can control the height of the glue coating component 1 through the hydraulic cylinder lifter 7, so as to realize the control of the glue coating thickness of the glue coating head. At the same time, the glue coating component 1 can be lifted when necessary to facilitate the subsequent inspection, maintenance and other operations.

[0037] In some embodiments, in combination Figure 2 As shown, the working end of the gluing head 12 is provided with a boost chamfer 122. The gluing head with the boost chamfer 122 can generate a downward force component during the gluing process, so that the glue fits the cardboard more closely, thereby improving the gluing effect.

[0038] In some embodiments, in combination Figure 1 , Figure 3 As shown, it also includes a cardboard conveyor belt 4, which is located below the gluing component 1 and can convey the cardboard to the bottom 1 of the gluing component 1 at a predetermined speed. The conveying speed of the cardboard conveyor belt 4 and the glue output speed of the glue nozzle 11 are coordinated to ensure the balance between speed and quality.

[0039] In some embodiments, in combination Figure 3As shown, the cardboard conveyor belt 4 is provided with a cardboard positioning groove 41, the depth of the cardboard positioning groove 41 does not exceed the thickness of the cardboard, the cardboard positioning groove 41 can fix the position of the cardboard in the axial direction, and ensure that the cardboard will not shift during the gluing process, thereby affecting the gluing effect.

[0041] In some embodiments, in combination Figure 2 As shown, it also includes an electric control switch 6, which is fixedly connected to the gluing component 1, and the electric control switch 6 on each of the gluing components 1 is connected to an external PLC controller. The electric control switch 6 of each gluing component 1 is centrally controlled by the PLC controller, so that the start-up control of each gluing component 1 can be achieved during the gluing process, thereby improving the controllability of the gluing result and enriching the gluing capacity of the cardboard gluing machine.

[0042] Working process: the cardboard passes through the coating component 1 at a predetermined speed under the clamping action of the feeding auxiliary wheel 5 of the cardboard conveyor belt 4; in the process of passing, since the multiple coating components 1 are evenly arranged above the cardboard, and each gluing component 1 is independently controlled by an external PLC controller, by controlling the start and stop of the gluing component 1, gluing can be performed only at the planned position, for example: intermittent gluing, and at the same time, by partially overlapping the gluing areas of the gluing component 1 on the second fixed rod 3 and the gluing component 1 on the first fixed rod 2, further control of the gluing width can be achieved; in the entire gluing process, the hydraulic cylinder lifter 7 indirectly controls the distance between the gluing head 12 and the cardboard by adjusting the height of the gluing component 1, thereby achieving regulation of the glue thickness.

[0043] In some embodiments, the gluing component 1 on the second fixed rod 3 is connected to a driving motor 31, and can move along the second fixed rod 3 under the action of the driving motor 31, so as to meet the intermittent gluing requirements of different spacings. At the same time, the gluing component 1 on the second fixed rod 3 can move axially during the gluing process, so as to realize more diverse planning of the gluing area.
