Description

Technical Field

[0001] The utility model relates to an SPC stone plastic floor laminating and gluing machine, belonging to the field of composite floor manufacturing equipment. Background Art

[0002] The SPC floor gluing process mainly involves applying phenolic resin on the floor surface through the extrusion of an extrusion tube and the movement of a scraper. The higher the ambient temperature of the phenolic resin, the faster it cures. In addition, a large amount of heat is released during the curing of the phenolic resin. Therefore, the gluing process in the prior art easily causes the phenolic resin to accumulate locally, and the local curing generates heat rapidly. This heat also generates heat accumulation, which seriously affects the uniform flow and coating of the phenolic resin glue. Utility Model Content

[0003] The technical purpose of the utility model is to overcome the technical problem that the gluing method in the prior art is prone to heat accumulation of phenolic resin, and to provide an SPC stone plastic floor gluing machine.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An SPC stone plastic floor laminating and gluing machine, comprising:

[0006] An inner shell, the middle part of which is divided into a feed chamber and a circulating cooling chamber by a partition plate, an inner wall of one end of the feed chamber of the inner shell being rotatably connected to a feed cover shell through a first sliding sealing ring, the feed cover shell being connected to a feed valve, an inner wall of one end of the circulating cooling chamber of the inner shell being rotatably connected to a water inlet cover shell through a second sliding sealing ring, the water inlet cover shell being connected to a water inlet valve, a drain cover shell being rotatably connected to the outer wall of one end of the circulating cooling chamber of the inner shell being connected to a drain valve;

[0007] A plurality of U-shaped heat exchange tubes are fixed in the inner shell through a partition plate array. The U-shaped bending portion of the heat exchange tube is located in the feed cavity. A water inlet diverter plate and a drainage diverter plate are sequentially arranged on the inner wall of the circulating cooling cavity. One end of the heat exchange tube passes through the drainage diverter plate and the water inlet diverter plate in sequence, and the other end of the heat exchange tube passes through the drainage diverter plate. A plurality of drainage holes are also provided in the inner shell at positions corresponding to the positions between the water inlet diverter plate and the drainage diverter plate. The drainage holes are connected to the drainage cover.

[0008] The outer shell has a first support ring and a second support ring fixed at both ends respectively. The outer shell is coaxially fixed to the outer side of the inner shell through the first support ring and the second support ring. A plurality of main discharge openings are arranged in an array on the wall of the inner shell corresponding to the feed cavity; an annular discharge cavity is arranged between the outer shell and the inner shell, and a plurality of auxiliary discharge openings are arranged in an array on the outer wall of the outer shell. The main discharge opening and the auxiliary discharge opening are connected through the discharge cavity.

[0009] As a further improvement of the present invention, the feed cover and the first sliding sealing ring are an integral structure, and the diameter of the feed cover is larger than the inner diameter of the inner shell; the water inlet cover and the second sliding sealing ring are an integral structure, and the diameter of the water inlet cover is larger than the inner diameter of the inner shell;

[0010] Because the inner shell is mainly supported and fixed by the connection between the feed cover shell and the water inlet cover shell relative to the bracket, the first sliding sealing ring and the second sliding sealing ring of the integrated structure can have better rolling support and coaxiality.

[0011] As a further improvement of the present invention, a first contact ring is vertically provided on the outer wall of one end of the circulating cooling chamber of the inner shell, and a second contact ring is provided on the outer side wall of the water inlet cover; the drainage cover is provided between the first contact ring and the second contact ring;

[0012] The drain cover is axially limited by the first contact ring and the second contact ring, which has better stability and prevents the drain cover from falling out.

[0013] As a further improvement of the present invention, the drainage cover comprises a main sealing sleeve slidably connected to the outer wall of the inner shell and a secondary sealing sleeve in sliding sealing contact with the first contact ring, and the end of the main sealing sleeve is in sliding contact with the second sealing ring; a connecting ring is provided at the connection position between the main sealing sleeve and the secondary sealing sleeve and is arranged obliquely with respect to the axis of the inner shell, a drainage cavity is provided in the connecting ring, and a drainage valve is provided on the connecting ring;

[0014] The drain cover is an L-shaped structure with a larger sliding sealing area and higher sealing efficiency.

[0015] As a further improvement of the present invention, a plurality of support frames are suspended in the inner shell. The support frames are hollow structures. A plurality of support sleeves are arranged in an array on the support frames. The heat exchange tubes are sleeved in the support sleeves.

[0016] The heat exchange tube is directly supported and fixed by the support frame of the hollow structure, which can reduce the heat exchange tube from bending or even colliding with the inner wall of the inner shell during rotation, thereby affecting the structural stability.

[0017] As a further improvement of the present invention, a heat exchange jacket is further sleeved on the inner shell, and a plurality of long strip discharge grooves are arranged in an annular array on the heat exchange jacket, the main discharge opening is located in the discharge groove, and a plurality of heat exchange fins are arranged in an array on the heat exchange jacket;

[0018] The setting of heat exchange fins further improves the heat exchange efficiency and reduces the possibility of heat accumulation.

[0019] As a further improvement of the present invention, a nylon rubber sleeve is sleeved on the outer side of the outer shell, and a plurality of surface holes arranged coaxially with the auxiliary discharge opening are arranged in an array on the rubber sleeve;

[0020] The rubber roller sleeve is made of nylon material with a relatively large thermal resistance value, which can further reduce the curing speed of the low-temperature phenolic resin in the outer shell by insulating the outer shell.

[0021] As a further improvement of the present invention, the first support ring and the outer shell are an integral structure, the second support ring is fixed to the end of the outer shell through a flange, and a sealing protrusion ring is provided on the inner ring of the second support ring for sealing contact with the inner shell. The one-way integrated structure of the outer shell ensures strength and pressure resistance.

[0022] The beneficial effects of the utility model are:

[0023] The utility model designs a set of phenolic resin coating rollers with a heat exchange structure, which keeps the phenolic resin at a relatively low storage temperature through the heat exchange mechanism and reduces the possibility of heat accumulation caused by large amounts of phenolic resin extruded through the coating rollers.
