Description

Technical Field

[0001] The invention relates to the field of refrigeration device manufacturing equipment, in particular to an aluminum tube winding heat shrink film device. Background Art

[0002] The refrigerator evaporator is commonly known as the tube-plate evaporator. It is the main heat exchange device in the refrigerator refrigeration system. Its function is to make the low-temperature and low-pressure liquid refrigerant evaporate (boil) into steam quickly, absorb the heat of the cooled material, and reduce the temperature of the refrigerated (frozen) material to achieve the purpose of refrigeration. The plate-tube evaporator is constructed by bonding the aluminum tube and the aluminum plate together with hot melt adhesive. In the prior art, the heat shrink film is usually attached to the aluminum plate first and then bonded to the aluminum tube. Since the fixing point is limited to the contact part between the aluminum tube and the aluminum plate, the heat shrink film attached outside the bonding part of the aluminum tube is wasted. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide an aluminum tube winding heat shrink film device.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A device for wrapping an aluminum tube around a heat shrinkable film comprises a frame and a linear guide rail arranged on the frame, a slide plate is installed on the linear guide rail, a base plate is arranged on the slide plate, a heat shrinkable film fixing frame is installed on the base plate, a roller is arranged at one end of the heat shrinkable film fixing frame, an aluminum tube slide groove is arranged on the side of the roller, the aluminum tube slide groove is fixed to the base plate, a first motor is installed on the frame and drives the slide plate to perform linear reciprocating motion through a belt; arranged at one end of the frame are a driving roller and a driven roller installed in parallel and closely, the driving roller is connected to a second motor, and arranged at the upper ends of the driving roller and the driven roller is a pressure plate, the pressure plate is connected to a cylinder, and the cylinder is installed on the frame through a bracket.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The invention discloses a device for winding a heat shrink film around an aluminum tube. After a rolled heat shrink film is mounted on a heat shrink film fixing frame, an active roller and a driven roller are driven by a motor to rotate in coordination with each other and drive an aluminum tube placed therein to rotate to complete the winding of the heat shrink film. Winding the heat shrink film around the aluminum tube not only saves the use cost of the heat shrink film but also ensures product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] See attached Figure 1-Figure 5 As shown, an aluminum tube winding heat shrink film device includes a frame 1 and a linear guide 2 arranged on the frame 1, a slide plate 3 is installed on the linear guide 2, a base plate 4 is arranged on the slide plate 3, a heat shrink film fixing frame 5 is installed on the base plate 4, a roller 6 is arranged at one end of the heat shrink film fixing frame 5, an aluminum tube slide groove 7 is arranged on the side of the roller 6, and the aluminum tube slide groove 7 is fixed on the base plate 4, a first motor 8 is installed on the frame 1 and drives the slide plate 3 to perform linear reciprocating motion through a belt 9; arranged at one end of the frame 1 are a driving roller 10 and a driven roller 11 installed in parallel and closely, the driving roller 10 is connected to a second motor 12, and arranged at the upper ends of the driving roller 10 and the driven roller 11 is a pressing plate 13, the pressing plate 13 is connected to a cylinder 14, and the cylinder 14 is installed on the frame 1 through a bracket 15.

[0014] When in use, first install the heat shrink film in the form of a disc on the heat shrink film fixing frame 5, which is a cylindrical rotating shaft, and then place the aluminum tube at the same time in the clamping position of the active roller 10 and the driven roller 11 and in the aluminum tube slide groove 7, and fix the aluminum tube between the active roller 10 and the driven roller 11. The operator passes one end of the heat shrink film through the roller 6 and adheres it to the aluminum tube. Under the control of the control system, the cylinder 14 starts and drives the pressure plate 13 connected thereto to limit the aluminum tube between the active roller 10 and the driven roller 11, and the first motor 8 and the second motor 12 rotate at the same time, wherein the rotation of the first motor 8 will drive the slide plate 3 to move linearly through the belt 9, and the rotation of the second motor 12 will drive the active roller 10 to rotate. Since the aluminum tube is limited between the active roller 10 and the driven roller 11, the aluminum tube also rotates at this time, and the heat shrink film will be wound around the aluminum tube under the drive of the two motors.

[0015] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the content of the present invention still falls within the protection scope of the present invention.
