[0021] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, and is not all the embodiment.

[0022] Referring to Figures 1-4 A carton forming and sealing device, comprising a fixed plate 1 and a glue brushing roller machine 2, the fixed plate 1 is provided with a sealing mechanism for the glue brushing roller machine 2 to seal on the carton;

[0023] As Figure 1 , Figure 3 and Figure 4 shown, the sealing mechanism comprises a sliding rod 3 fixedly installed on the top of the glue brushing roller machine 2, a sliding sleeve block 4 is slidably sleeved on the sliding rod 3, a sliding port 5 is formed on the fixed plate 1, the sliding sleeve block 4 is slidably arranged on the inner side wall of the sliding port 5, a pneumatic cylinder 6 is fixedly installed on the bottom of the fixed plate 1, and the piston end of the pneumatic cylinder 6 is fixedly connected with the outer side wall of the sliding sleeve block 4.

[0024] Further description, the design of the sealing mechanism makes the glue brushing roller machine 2 realize flexible adjustment of the up-down position under the action of the pneumatic cylinder 6, so that the sealing operation can better adapt to cartons of different heights or specifications, and the glue can be accurately applied to the position to be sealed, thereby improving the accuracy and applicability of sealing.

[0025] As Figure 1 shown, the inner side wall of the sliding port 5 is provided with two limiting grooves 12, and a limiting sliding ring 13 is fixedly sleeved on the sliding sleeve block 4, and the outer side wall of the limiting sliding ring 13 is slidably connected with the inner side wall of the limiting groove 12.

[0026] Further description, the limiting structure can ensure that the sliding sleeve block 4 does not deviate or shake when sliding in the sliding port 5, so that the glue brushing roller machine 2 moves more stably during the up-down movement, thereby ensuring the continuity of the sealing process and the stability of the sealing quality, and avoiding problems such as uneven glue application caused by equipment shaking.

[0027] As Figure 1 shown, the glue brushing roller machine 2 is composed of a fixed frame, a glue dropper and a glue brushing roller, the sliding rod 3 is fixed on the top of the fixed frame, the glue dropper is fixed on the inner top of the fixed frame, and the glue brushing roller rotates on the inner side wall of the fixed frame.

[0028] Further description, the glue dropper is fixed on the inner top of the fixed frame to provide glue for the glue brushing roller in time, and the glue brushing roller rotates on the inner side wall of the fixed frame to uniformly apply glue on the carton, so that the glue supply and application are more orderly and reasonable, and the sealing position of the carton can obtain appropriate and uniform glue, thereby achieving good sealing effect, and the glue brushing roller machine 2 is a common means in the prior art, which will not be described in detail here.

[0029] As Figure 2 shown, the fixed plate 1 is provided with a pressing mechanism, the pressing mechanism includes a support frame 7 fixedly installed on the fixed plate 1, a sliding groove 8 is formed in the support frame 7, a T-shaped fixed rod 9 is fixedly installed at the top of the sliding rod 3 and slides with the inner wall of the sliding groove 8, a matching sliding plate 10 is sleeved and slides with the top of the support frame 7, a spring 11 is sleeved and slides with the T-shaped fixed rod 9, and the two ends of the spring 11 are fixedly connected with the inner top of the T-shaped fixed rod 9 and the top of the matching sliding plate 10 respectively.

[0030] Further explanation, in the pressing mechanism, when the glue brushing roller machine 2 is pressed to contact the surface of the carton, if the surface of the carton has uneven ups and downs, the spring 11 can make the glue brushing roller machine 2 adaptively adhere to the surface of the carton through the self-elastic property, ensure that the glue brushing roller fully contacts the carton, make the glue evenly coated on the carton, improve the glue sealing effect, and avoid the phenomenon of local glue leakage or uneven glue amount.

[0031] As Figure 1 shown, the vertical distance between the inner top of the support frame 7 and the fixed plate 1 remains unchanged first and then gradually increases and finally remains unchanged.

[0032] Further explanation, this special space structure layout will not hinder the normal up-down movement and pressing operation of the glue brushing roller machine 2.
