The present embodiment provides a press-coating device whose basic structure and principle are as follows, which comprises a conveyor belt, two supports and a control device. The side plates are placed on the conveying belt and move forward continuously along with the belt. The two supports are respectively arranged on two sides of the belt, the control device is erected between the two supports, and the control device is positioned on the upper side of the belt. The control device is provided with the installation axle on the arm or arms that the belt stretches out, and the wheel that covers is pressed and is located on the installation axle through the bearing housing. The control device controls the pressure applied to the side plate by the pressing wheel, the conveying belt drives the pressing wheel to rotate when moving, the pressing wheel applies pressure to the aluminum foil adhesive tape, and the aluminum foil adhesive tape fixes the condensation pipe on the side plate. It should be clear that the basic architecture and principle of the press-on device described above is only exemplary and not exclusive.

As shown in fig. 1 to 4 and 8, the pressing wheel of the present embodiment includes a first bearing 100, a coupling shaft 300, and at least three rollers 400. The first bearing 100 is disposed on the mounting shaft, and when the conveyor belt moves, the roller 400 can rotate relative to the belt. The roller 400 continuously applies pressure to the aluminum foil tape during rotation to fix the condensation duct to the side plates. The roller 400 can rotate, so that the friction force between the roller 400 and the aluminum foil tape can be reduced, the service life of the roller 400 is prolonged, and the roller 400 is prevented from influencing the conveying of the side plates.

The connecting shaft 300 and the first bearing 100 are coaxially sleeved on the first bearing 100, the connecting shaft 300 is used for bearing the roller 400, and the connecting shaft 300 is used for enabling at least three rollers 400 on the connecting shaft to be stressed uniformly. The length of the coupling shaft 300 is not particularly limited and is flexibly set according to the number and size of the rollers 400. The first bearing 100 may be located at one side or a middle position of the connecting shaft 300, and is not particularly limited herein.

As shown in fig. 2, 3, 4 and 8, at least three rollers 400 are sequentially sleeved on the connecting shaft 300, each roller 400 includes a rim 410 and a plurality of elastic members disposed inside the rim 410 and abutting against the connecting shaft 300, and during the rotation of the rim 410, the peripheral wall of the rim 410 abuts against the object to be pressed and deforms to form a pressing surface 411, so that a total pressing surface 430 formed by the pressing surfaces 411 of each rim 410 abuts against the pressing surface. The specific way of deforming the outer peripheral wall of the rim 410 is not limited, for example, the elastic member may be used to move the pressing surface 411 of the single rim 410 along the radial direction of the rim 410 under the action of external force, so that the total pressing surface 430 formed by the pressing surface 411 of each rim 410 is attached to the object to be pressed; the rim 410 may be elastic and deformable.

The upper limit of the number of the rollers 400 is not limited, and may be specifically set according to the requirement, and in this embodiment, the number of the rollers is 4. The roller 400 is sleeved on the connecting shaft 300, so that the roller 400 is uniformly stressed. The type of the elastic member is not particularly limited, and may be, for example, a spring, an elastic member made of an elastic material, or a structural member having elasticity, which means that the structure itself makes the structural member have elasticity. The number and mounting position of the elastic members are not particularly limited, and it is sufficient if the pressing surface 411 of the rim 410 can be moved in the radial direction of the rim 410.

The pressure contact surface 411 of the rim 410 is a surface of the outer peripheral wall of the rim 410 that is coming into contact with the object to be pressure-contacted, and as shown in fig. 2 and 8, the outer peripheral wall of the rim 410 is the entire outer peripheral wall of the rim 410, and the pressure contact surface 411 is a surface below the outer peripheral wall that is coming into contact with the object to be pressure-contacted. That is, the outer peripheral wall of the rim 410 is alternately changed to the crimping surface 411 during the rotation of the coating wheel, or it can be understood that when a part of the outer peripheral wall of the rim 410 is rotated to be downwardly attached to the object to be crimped, the part of the outer peripheral wall becomes the crimping surface 411, and when the part of the outer peripheral wall is rotated to be away from the object to be crimped, the part of the outer peripheral wall is not called the crimping surface 411.

In the present embodiment, as shown in fig. 2 and 8, the object to be compression bonded includes a condensation duct, a side plate adjacent to the condensation duct, and an aluminum foil tape on the condensation duct and the side plate. The pressing surfaces 411 of all the rims 410 form the total pressing surfaces 430, and since the pressing surface 411 of each rim 410 can move along the radial direction of the rim 410, when encountering a protruding condenser tube, the pressing surface 411 of the rim 410 can move along the radial direction of the rim 410 towards the rim 410, namely, is recessed inwards, so that the shape of the total pressing surface 430 is matched with the object to be pressed, namely, the total pressing surface 430 is attached to the object to be pressed. Can be so that treat that the crimping thing all receives pressure, avoid producing the clearance between aluminium foil and the condenser pipe or and the curb plate to lead to the heat dissipation not smooth.

Moreover, due to the existence of the elastic member, when the crimping surface 411 rotates away from the object to be crimped, the crimping surface 411 can be rapidly restored. When objects to be pressed in different shapes are encountered again, the pressing surface 411 of the rim 410 can be radially moved according to the shape of the pressing surface 411, so that the total pressing surface 430 is attached to the objects to be pressed in different shapes. Therefore, the press wheel of the embodiment has a wide application range. Because the pressing wheel of the embodiment is in a rolling type and the elastic piece exists, the object to be pressed with the pressing shape changing at any time can be pressed in the pressing process.

It can be seen that the pressing surface 411 of the rim 410 can move along the radial direction of the rim 410, so that the shape of the total pressing surface 430 is adapted to the object to be pressed, i.e. the total pressing surface 430 is attached to the object to be pressed. Can be so that treat that the crimping thing all receives pressure, avoid producing the clearance between aluminium foil and the condenser pipe or and the curb plate, avoid the heat dissipation that the clearance leads to not smooth. Because the pressing wheel of the embodiment is rolling and the elastic piece exists, the pressing wheel can press the object to be pressed with the shape changing at any time in the pressing process, and the pressing wheel of the embodiment has wide application range. The rolling type pressing wheel can reduce the friction force between the pressing wheel and the aluminum foil adhesive tape, prolong the service life of the pressing wheel and avoid the influence of the pressing wheel on the conveying of the side plates.

In some embodiments, as shown in fig. 2, 6 and 8, the rollers 400 abut one another. The rollers 400 abut against each other so that the total pressing surface 430 formed by the pressing surfaces 411 of the rollers 400 is continuous, which can form a better coating on the object to be pressed, or it can be understood that the total pressing surface 430 can be completely attached to the object to be pressed, thereby avoiding an empty stressed area of the object to be pressed, and avoiding a gap between the aluminum foil and the condenser tube or between the aluminum foil and the side plate, which results in poor heat dissipation.

In some embodiments, as shown in fig. 1, 5 and 7, the resilient member includes a plate body 420, and the plate body 420 gradually rolls inward while extending from the rim 410 to a position lower than the coupling shaft 300. As shown, the plate body 420 is inwardly rolled to form a cavity, which provides the plate body 420 with a certain elasticity, so that the pressing surface 411 of the rim 410 can move toward the rim 410 along the radial direction of the rim 410. In some embodiments, the elastic members are uniformly distributed along the circumferential direction of the rim 410, and the elastic members are uniformly distributed along the circumferential direction of the rim 410 such that the elastic force of the rim 410 is uniform.

In some embodiments, as shown in fig. 6 to 7, the pressing wheel further includes a buffer sleeve 500, and the buffer sleeve 500 is sleeved on each rim 410. The buffer sleeve 500 is used to avoid the hard contact between the rim 410 and the object to be pressed, and avoid the damage to the object to be pressed. Optionally, the material of the cushion cover 500 is nylon, and the nylon has suitable hardness and wear resistance.

In some embodiments, as shown in fig. 3, 4 and 6, the pressing wheel further includes a second bearing 200, one end of the connecting shaft 300 is sleeved on the first bearing 100, and the other end of the connecting shaft 300 is sleeved on the second bearing 200. That is, the first bearing 100 and the second bearing 200 are respectively disposed at two ends of the connecting shaft 300, and the connecting shaft 300 is stressed more uniformly due to the arrangement of the bearings, and the roller 400 is stressed more uniformly due to the more uniform stress of the connecting shaft 300.

In some embodiments, as shown in fig. 1 to 8, the connecting shaft 300, the rim 410 and the cushion collar 500 are all cylindrical, so that the pressing wheel is uniformly stressed, and the pressing wheel is simple in structure and convenient to assemble.

In some embodiments, as shown in fig. 2, 3, 4, 6 and 8, the number of the rollers 400 is four, and the four rollers 400 are respectively sleeved on the connecting shaft 300 in sequence. In the present embodiment, the number of the rollers 400 is four, which is enough to completely cover the object to be crimped, and it is obvious that the number of the rollers 400 is only exemplary, and the specific number of the rollers 400 can be set according to specific needs, for example, the number of the rollers 400 can be 3, 5, or 8, etc.
