Gluing machine capable of preventing blistering during plastic flooring compounding

Abstract

The utility model discloses a gluing machine capable of preventing blistering during plastic flooring compounding. The gluing machine comprises a rack, a compression roller mounted on the rack, and a gluing roller arranged on one side of the compression roller, and bulges are arranged on the circumferential surface of the gluing roller. Due to the arrangement of the protrusions, the plastic flooring passing through the space between the glue coating roller and the pressing roller can be tightly compacted, meanwhile, glue can be conveniently smeared on the plastic flooring, and the glue is promoted to be distributed on the plastic flooring at intervals through the gaps between the protrusions; therefore, when the plastic flooring is attached, air flows out through the gaps between the protrusions, and the phenomenon that the plastic flooring is blistered when attached is avoided. On the basis, the embossments are adopted to form the patterns on the gluing roller, so that air can be effectively exhausted when the plastic flooring is attached, and the bulging phenomenon is prevented.

Description

Technical Field

[0001] The utility model relates to the technical field of compounding machines, in particular to a glue coating machine which can prevent floor leather from bubbling during compounding. Background Art

[0002] When laminating floor leather, a pressure roller and a glue coating roller are usually used to cooperate with each other to achieve the lamination of the floor leather. However, the outer wall surface of the existing glue coating roller is flat, so the glue coating roller applies glue to the floor leather without gaps during rolling. Since there are no gaps in the glue on the floor leather, the floor leather is prone to bulging during bonding. Utility Model Content

[0003] The utility model aims to provide a glue coating machine which can prevent floor leather from bubbling during lamination, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a glue coating machine for preventing bubbling during the compounding of floor leather, comprising a frame, a pressure roller installed on the frame, and a glue coating roller provided on one side of the pressure roller, and a protrusion is provided on the circumferential surface of the glue coating roller.

[0005] As a preferred technical solution of the utility model: the number of the protrusions is multiple and they are equidistantly distributed in the length direction of the glue coating roller.

[0006] As a preferred technical solution of the utility model: the protrusion is in the shape of a wavy line.

[0007] As a preferred technical solution of the utility model: the protrusion has a crest, and troughs are formed on both sides of the crest.

[0008] As a preferred technical solution of the utility model: the width between the trough and the crest is a, and the width between the crest and the trough is b, and a≥b.

[0009] By adopting the above technical solution, the utility model has the following beneficial effects: due to the setting of the protrusions, the floor leather passing between the glue coating roller and the pressure roller can be tightly compacted while facilitating the application of glue on the floor leather, and the gaps between the protrusions are used to promote the distribution of glue on the floor leather at intervals, so that when the floor leather is attached, air flows out through the gaps between the protrusions to avoid bubbling when the floor leather is attached. Based on this, the pattern formed by the protrusions on the glue coating roller is used to effectively remove air when the floor leather is attached to prevent the occurrence of bulging.

[0015] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0016] See also Figure 1-4 The utility model provides an embodiment: a glue coating machine for preventing floor leather from bubbling during lamination, comprising a frame 1, a pressure roller 2 installed on the frame 1, and a glue coating roller 3 is provided on one side of the pressure roller 2, and a protrusion 4 is provided on the circumferential surface of the glue coating roller 3.

[0017] In summary, due to the setting of the protrusions 4, the floor leather passing between the glue roller 3 and the pressure roller 2 can be tightly compacted while the glue is easily applied to the floor leather, and the gaps between the protrusions 4 are used to promote the glue to be distributed on the floor leather at intervals, so that when the floor leather is attached, the air flows out through the gaps between the protrusions 4 to avoid the floor leather from bubbling when attached. Based on this, the pattern formed by the protrusions 4 on the glue roller is used to effectively remove air when the floor leather is attached to prevent the occurrence of bulging.

[0018] In order to further improve the bonding effect of the floor leather, the number of the protrusions 4 is multiple and they are evenly distributed in the length direction of the glue coating roller 3. Therefore, the use of multiple evenly distributed protrusions 4 can improve the exhaust effect, thereby preventing the floor leather from bulging during bonding or compounding with other film materials.

[0019] Specifically, the protrusion 4 is wavy, so the wavy protrusion 4 can promote the glue to be applied on the floor leather in a wavy shape, thereby making the glue lines on the floor leather intricate, so that the floor leather has a reliable connection effect after bonding or after the floor leather and the film material are compounded.

[0020] Meanwhile, the protrusion 4 has a crest 5, and a trough 6 is formed on both sides of the crest 5. The width between the trough 6 and the crest 5 is a, and the width between the crest 5 and the trough 6 is b, and a≥b.

[0021] By the above method, the exhaust speed of the floor leather during the bonding process can be further improved to reduce the occurrence of bulging, so as to improve the firmness of the floor leather after bonding. At the same time, a≥b, so that the pattern formed by the protrusion 4 is irregular, and then the shape of the glue is also irregular, and the width of the glue on the same line formed by the protrusion 4 is inconsistent, thereby ensuring the exhaust effect and the firmness of the floor leather after bonding. Specifically, the width of a is preferably 1-2 mm.

[0022] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
