Edge band gluing and pressing device

Abstract

The utility model relates to an edge band gluing and pressing device which comprises a groove body, a gluing wheel, a pressing wheel assembly and a gap adjusting assembly, and when the edge band gluing and pressing device is used, a worker can move the pressing wheel in the direction towards or away from the gluing wheel through the gap adjusting assembly; and the gap between the glue pressing wheel and the glue coating wheel is adjusted to a proper size, so that the glue liquid in the glue storage tank is uniformly pressed and coated on the surface of one side of the edge band under the driving of the rotating glue coating wheel. The elastic piece is used for providing buffering force for the pressing wheel, so that the situation that the pressing wheel arm is lifted up due to shaking or rolling and pulling of the edge sealing strip is effectively prevented, and therefore the probability that due to vibration of the pressing wheel arm, gluing is not uniform or some places of the edge sealing strip cannot be glued is reduced. Therefore, the edge band gluing and pressing device can be used for reliably and uniformly gluing the edge band.

Description

Technical Field

[0001] This utility model relates to the field of edge banding processing technology, and in particular to an edge banding adhesive pressing device. Background Technology

[0002] Currently, the pressing method of domestic furniture edge banding extrusion adhesive applicators is a pair of straight rods and wheels, with the upward and downward pressure controlled by a screw. This method cannot control the tightness of the pressing strip, resulting in inconsistent glue thickness; moreover, the screw control switch lacks a locking device, which can easily loosen over time, leading to a loose pressing strip and incomplete glue application. Utility Model Content

[0003] Therefore, it is necessary to provide a sealing strip gluing device that can reliably and uniformly apply glue.

[0004] An edge banding adhesive application and pressing device, comprising:

[0005] The tank body has a glue storage tank;

[0006] A glue-applying wheel is rotatably mounted on the tank body, with at least a portion of the glue-applying wheel located within the glue storage tank;

[0007] The pressure roller assembly includes a support structure, a pressure roller arm, an elastic element, and a pressing roller mounted on one end of the pressure roller arm. The pressing roller is spaced apart from the coating roller and located outside the glue storage tank. The end of the pressure roller arm away from the pressing roller has a rotatable connection point and a limiting part. The support structure has a rotatable mounting point. The rotatable mounting point is rotatably connected to the rotatable connection point. The end of the pressure roller arm away from the pressing roller is also provided with a limiting part. The elastic element is used to drive the pressure roller arm to rotate the pressing roller in the direction toward the coating roller until the limiting part abuts against the support structure. The elastic element is used to provide an elastic force to drive the pressure roller arm to rotate the pressing roller in the direction toward the coating roller, and to make the limiting part abut against the support structure.

[0008] A gap adjustment assembly is connected to the support structure and is configured to drive the support structure to move the pressure roller in a direction toward or away from the coating roller.

[0009] In one embodiment, the gap adjustment assembly includes a housing, an adjustment block with an adjustment screw hole, and an adjustment screw; a through hole is provided on the side wall of the housing; the adjustment block is slidably installed inside the housing; the adjustment screw passes through and is screwed into the adjustment screw hole, and is rotatably connected to the side wall of the housing; one end of the support structure passes through the through hole and is fixedly connected to the adjustment block; the adjustment screw is operable to rotate forward or backward to drive the adhesive roller to move in a direction toward or away from the adhesive roller via the adjustment block.

[0010] In one embodiment, the gap adjustment assembly further includes a locking member; the locking member has a locking portion at one end and an external thread at the other end;

[0011] The side wall of the housing has an elongated adjustment hole along the longitudinal direction of the adjustment screw; the adjustment block also has a locking screw hole; the locking member has an external thread end that passes through the adjustment hole and is screwed into the adjustment screw hole; the locking part is located outside the housing and can abut against the outer wall of the housing.

[0012] In one embodiment, the gap adjustment assembly further includes an adjustment handle; one end of the adjustment screw extends to the outside of the housing and is fixedly connected to the adjustment handle.

[0013] In one embodiment, the elastic element is a compression spring; the compression spring is clamped between the end of the pressure roller arm away from the pressure roller and the support structure, and is located on the side of the rotation connection point away from the limiting part; an adjusting threaded part serving as the limiting part is installed at the end of the pressure roller arm away from the pressure roller; the end of the adjusting threaded part abuts against the support structure.

[0014] In one embodiment, the support structure has a retaining groove at a position opposite to the adjusting threaded component; the retaining groove includes a limiting surface and a retaining surface connected to each other; the included angle between the limiting surface and the retaining surface is an acute angle, and the limiting surface is located on the side of the retaining surface away from the glue-applying wheel; the retaining surface is an inclined surface whose end away from the limiting surface is inclined in the direction toward the glue storage tank; one end of the adjusting threaded component can abut against the retaining surface.

[0015] In one embodiment, there are two rotating mounting points, which are spaced apart along the central axis of the pressure roller; one end of each of the two pressure roller arms is rotatably connected to both ends of the pressure roller; and the two rotating connection points are rotatably connected to the two rotating mounting points in a one-to-one correspondence.

[0016] There are two elastic elements; the two elastic elements are used to drive the two pressure roller arms to rotate around their respective rotation connection points, so as to simultaneously drive the glue-applying roller to move in a direction toward or away from the glue-applying roller.

[0017] The aforementioned edge banding adhesive applicator is used to evenly apply adhesive to one side of the edge banding strip that passes through the gap between the pressure roller and the applicator roller. During use, the operator can adjust the gap between the pressure roller and the applicator roller using the gap adjustment component, moving the pressure roller towards or away from the applicator roller. This ensures that the adhesive in the reservoir is evenly applied to one side of the edge banding strip by the rotating applicator roller. The elastic element provides a buffering force to the pressure roller, effectively preventing the pressure roller arm from lifting due to edge banding strip vibration or rolling / pulling. This reduces the probability of uneven adhesive application or missed areas on the edge banding strip caused by pressure roller arm vibration. Therefore, the aforementioned edge banding adhesive applicator can reliably and evenly apply adhesive to the edge banding strip. Attached Figure Description

[0024] Appendix Figure 1 The diagram illustrates the structure of a metal edge banding strip according to one embodiment of the present invention. For ease of explanation, the accompanying drawings only show structures relevant to embodiments of the present invention.

[0025] Please see Figure 1 The edge banding adhesive pressing device 100 in the preferred embodiment of this utility model includes a groove body 110, an adhesive roller 120, a pressing roller assembly 130, and a gap adjustment assembly 140.

[0026] The tank body 110 has a glue storage tank 111. The tank body 110 can be a shell structure assembled from multiple plates, or it can be a hollow structure formed in one piece. The glue storage tank 111 is used for glue liquid.

[0027] The applicator 120 is rotatably mounted on the tank body 110, with at least a portion of the applicator 120 located within the glue storage tank 111. In actual use, a portion of the applicator 120 is immersed in the glue solution within the glue storage tank 111.

[0028] The pressure roller assembly 130 includes a support structure 131, a pressure roller arm 132, an elastic element 133, and a pressure roller 134 mounted on one end of the pressure roller arm 132. The pressure roller 134 is spaced apart from the glue applicator 120 and located outside the glue storage tank 111. The end of the pressure roller arm 132 away from the pressure roller 134 has a rotatable connection point 1321 and a limiting part 1322. The support structure 131 has a rotatable mounting point 1311. The rotatable mounting point 1311 is rotatably connected to the rotatable connection point 1321. The end of the pressure roller arm 132 away from the pressure roller 134 is also provided with a limiting part 1322. The elastic element 133 is used to drive the pressure roller arm 132 to rotate the pressure roller 134 in the direction toward the glue applicator 120 until the limiting part 1322 abuts against the support structure 131. The elastic element 133 provides an elastic force that drives the pressure roller arm 132 to rotate the adhesive roller 134 in the direction toward the adhesive coating roller 120, and causes the limiting part 1322 to abut against the support structure 131. The elastic element 133 can be a compression spring, a torsion spring, a metal spring, etc.

[0029] The gap adjustment assembly 140 is connected to the support structure 131 and is configured to drive the support structure 131 to move the pressure roller 134 in a direction toward or away from the glue application roller 120. The gap adjustment assembly 140 can be a manually adjustable structure or an automatically adjustable structure driven by a motor, electric cylinder, or the like.

[0030] The pressure roller 134 can be located either on the top of the glue-applying roller 120, away from the glue reservoir 111, or on the side of the glue-applying roller 120. When the pressure roller 134 is on top of the glue-applying roller 120, the gap adjustment component 140 drives the support structure 131 to move the pressure roller 134 vertically; when the pressure roller 134 is on the side of the glue-applying roller 120, the gap adjustment component 140 drives the support structure 131 to move the pressure roller 134 laterally. Here, "vertical" can refer to the vertical direction or a direction slightly deviated from the vertical direction, and "lateral" can refer to the horizontal direction or a direction slightly deviated from the horizontal direction.

[0031] When it is necessary to apply adhesive to one side of the edge banding strip using the aforementioned edge banding strip gluing device 100, adhesive is added to the glue storage tank 111 until the bottom of the gluing tank is immersed in the adhesive; the gap adjustment component 140 is used to move the pressure roller 134 toward or away from the gluing roller 120 to adjust the gap between the pressure roller 134 and the gluing roller 120 to a suitable distance (the suitable gap distance means that the edge banding strip to be glued can pass through, and the pressure roller 134 can be glued away from the edge banding strip). (The gap distance between one side of the roller 120); pass one end of the edge banding strip to be coated through the gap between the pressure roller 134 and the coating roller 120; use the gap adjustment component 140 to move the pressure roller 134 in the direction toward the coating roller 120 until the pressure roller 134 presses against the side of the edge banding strip away from the coating roller 120, ensuring that the edge banding strip can pass through the gap between the pressure roller 134 and the coating roller 120, while the surface of the coating roller 120 can fully contact the surface of one side of the edge banding strip.

[0032] Therefore, during the edge banding adhesive application process, the aforementioned edge banding adhesive application device 100 uses the gap adjustment component 140 to press the pressure roller 134 against the side of the edge banding away from the adhesive application roller 120, ensuring complete contact between the edge banding and the surface of the adhesive application roller 120. This facilitates the even application of adhesive from the surface of the adhesive application roller 120 to one side of the edge banding. The elastic element 133 provides a buffering force to the pressure roller 134, effectively preventing the pressure roller arm 132 from lifting due to edge banding vibration or rolling / pulling, thereby reducing the probability of uneven adhesive application or missed areas of the edge banding caused by pressure roller arm 132 vibration. Therefore, the aforementioned edge banding adhesive application device 100 can reliably and evenly apply adhesive to the edge banding.

[0033] In some embodiments, the gap adjustment assembly 140 includes a housing 141, an adjustment block (not shown) with an adjustment screw hole, and an adjustment screw (not shown). A through hole (not shown) is provided on the side wall of the housing 141. The adjustment block is slidably mounted within the housing 141. The adjustment screw passes through and is screwed into the adjustment screw hole, and is rotatably connected to the side wall of the housing 141. One end of the support structure 131 passes through the through hole and is fixedly connected to the adjustment block. The adjustment screw is operably rotatable in the forward or reverse direction to drive the pressure roller 134 to move toward or away from the glue application roller 120 via the adjustment block.

[0034] Thus, the adjusting screw and the adjusting block cooperate to form a lead screw mechanism, which can convert the rotational motion of the adjusting screw into the linear motion of the adjusting block, so as to facilitate the driving of the support structure 131 to drive the pressure roller arm 132 to move in a straight line, and then drive the pressing roller 134 to move in the direction toward or away from the coating roller 120, thereby realizing the adjustment of the gap between the pressing roller 134 and the coating roller 120.

[0035] It should be noted that the rotation of the adjusting screw can be achieved manually by the staff using tools such as wrenches or handles or by hand, or it can be automatically driven by a device such as a motor.

[0036] Furthermore, in some embodiments, the gap adjusting assembly 140 further includes a locking member 142. One end of the locking member 142 has a locking portion (not shown), and the other end has an external thread (not shown). An elongated adjusting hole (not shown) is formed on the side wall of the housing 141 along the longitudinal direction of the adjusting screw. The adjusting block also has a locking screw hole. The threaded end of the locking member 142 passes through the adjusting hole and is screwed into the adjusting screw hole. The locking portion is located outside the housing 141 and abuts against the outer wall of the housing 141.

[0037] Thus, after the gap between the pressure roller 134 and the glue-applying roller 120 is adjusted to the correct position using the gap adjustment component 140, the operator turns the locking component 142 until the locking part presses against the outer wall of the housing 141, thereby locking the gap adjustment component 140 and locking the position of the adjusting block in the longitudinal direction of the adjusting screw. This prevents relative movement between the adjusting block and the adjusting screw caused by vibration of the edge banding strip during the glue application process, further ensuring the uniformity and reliability of the glue application to the edge banding strip.

[0038] When it is necessary to adjust the gap between the pressure roller 134 and the glue application roller 120, the operator needs to turn the locking part 142 in the opposite direction until the locking part leaves the outer wall of the housing 141, which will release the gap adjustment component 140.

[0039] Furthermore, in some embodiments, the gap adjustment assembly 140 also includes an adjustment handle 143. One end of the adjustment screw extends outside the housing 141 and is fixedly connected to the adjustment handle 143. The adjustment handle 143 can be annular, plate-shaped, rod-shaped, or similar structures. When it is necessary to adjust the gap between the pressure roller 134 and the glue application roller 120, the operator only needs to hold the handle and rotate it, greatly improving the ease of use of the edge banding glue application and pressure strip device 100.

[0040] In some embodiments, the elastic element 133 is a compression spring. The compression spring is clamped between the end of the pressure roller arm 132 away from the pressure roller 134 and the support structure 131, and is located on the side of the rotational connection point 1321 opposite to the limiting part 1322. An adjusting threaded member serving as the limiting part 1322 is installed at the end of the pressure roller arm 132 away from the pressure roller 134. The end of the adjusting threaded member abuts against the support structure 131.

[0041] In actual use, the operator can adjust the length of the threaded part that protrudes from the end face of the pressure roller arm 132 away from the pressure roller 134 by turning the threaded part. This allows for adjustment of the elastic force of the elastic part 133, and thus the buffering force that the elastic part 133 can provide to the pressure roller arm 132 can also be adjusted. This eliminates the effect of the pressure roller arm 132 lifting up due to edge banding vibration, edge curling and pulling during the edge banding adhesive application process, ensuring uniform adhesive application while also achieving high adhesive application efficiency.

[0042] Furthermore, in some embodiments, a retaining groove 1312 is formed at the position opposite to the adjusting threaded component on the support structure 131. The retaining groove 1312 includes a limiting surface 13121 and a retaining surface 13122 connected to each other. The included angle between the limiting surface 13121 and the retaining surface 13122 is an acute angle, and the limiting surface 13121 is located on the side of the retaining surface 13122 away from the glue applicator 120. The retaining surface 13122 is an inclined surface whose end away from the limiting surface 13121 is inclined in the direction toward the glue reservoir 111. One end of the adjusting threaded component can abut against the retaining surface 13122.

[0043] Thus, when the operator adjusts the elastic force of the elastic element 133 by turning the adjusting thread, the limiting surface 13121 can limit the extreme position of the adjusting thread on the abutment surface 13122 near the rotation connection point 1321, preventing the adjusting thread from slipping out of the abutment surface 13122 and ensuring the safety of the edge sealing strip adhesive pressing device 100. Furthermore, by setting the abutment surface 13122 as an inclined surface, the operator only needs to slightly turn one adjusting thread to effectively adjust the elastic force of the elastic element 133, saving time and effort and improving the sensitivity of the elastic force adjustment.

[0044] Furthermore, in some embodiments, there are two rotating mounting points 1311, which are spaced apart along the central axis of the pressure roller 134. One end of each of the two pressure roller arms 132 is rotatably connected to both ends of the pressure roller 134. The two rotating connection points 1321 are rotatably connected to the two rotating mounting points 1311 in a one-to-one correspondence.

[0045] There are two elastic elements 133. The two elastic elements 133 are used to drive the two pressure roller arms 132 to rotate around their respective rotation connection points 1321, so as to simultaneously drive the glue-applying roller 134 to move in a direction toward or away from the glue-applying roller 120.

[0046] In this way, by setting two rotating mounting points 1311, two pressure roller arms 132, and two elastic elements 133, the pressure roller 134 can achieve two-point support in its axial direction through each connection between the two pressure roller arms 132 and the support structure 131. This can effectively improve the connection stability between the pressure roller 134 and the support structure 131, and further improve the stability and reliability of the pressure roller 134 in the glue application process.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
