Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic welding trolley for heat-insulating blankets. Background Art

[0002] With the development of solar greenhouses, in order to enable them to be used in higher latitudes, more and more new types of insulation blankets are being developed to resist the severe cold in winter. Among them, chemically synthesized rubber-plastic cotton insulation blankets have higher thermal resistance and air tightness than traditional quilts. However, when using this type of insulation blanket, two pieces of insulation blankets need to be manually aligned and welded together using a hot melt machine. Factors such as the force size, force direction, and hot melt machine temperature during manual welding will affect the welding quality of the insulation blanket. Insulation blankets with poor welding quality are prone to breakage and their thermal insulation and air tightness will decrease.

[0003] The rubber-plastic-cotton insulation blanket is divided into three layers, the outer side is wrapped with black and white PE cloth, and the middle is the insulation rubber-plastic-cotton. The heat-sealing process of PE cloth has been perfected. Two layers of PE cloth are stacked, covered with Teflon tape, and then rolled at about 200 degrees Celsius using a hot melt machine to heat-seal the two layers of PE cloth. The handheld hot melt machine is difficult to control the hot melt temperature, hot melt time, pressing force, etc., and the operation is hindered due to the limited standing position when operating on the greenhouse shed. The present invention proposes an automatic welding trolley for insulation blankets. Summary of the invention

[0004] Based on the above deficiencies in the prior art, the present invention provides an automatic welding trolley for heat-insulating quilts.

[0005] The technical scheme of the present invention is as follows: an automatic welding trolley for insulating blankets, comprising a trolley body 2 and a hot melt module 3; the hot melt module 3 is located below the trolley body 2, and comprises two roller motors 3-1, Teflon tape 3-2, and a heating module 3-3; the Teflon tape 3-2 is sleeved on the two roller motors 3-1 to form a two-layer conveyor belt form; the lower conveyor belt is tightly attached to the top layer of the rubber-plastic cotton insulating quilt; the heating module 3-3 is located between the Teflon tapes 3-2 to heat the Teflon tape 3-2; the movement of the trolley body 2 drives the roller motor 3-1 to rotate, and the heated Teflon tape 3-2 moves on the top layer of the rubber-plastic cotton insulating quilt to weld the insulating quilt.

[0006] Furthermore, the trolley body 2 includes a frame 2-1 and a linear module; the linear module is located on the frame 2-1; the linear module includes a screw motor 4-1, a screw 4-2, a slider 4-3, and a guide rail 4-4; the screw motor 4-1 drives the screw 4-2 to rotate, and the slider 4-3 is connected to the screw 4-2 through a thread, with one side in the groove of the guide rail 4-4, and the screw motor 4-1 rotates to move the slider 4-3 along the guide rail 4-4; the slider 4-3 is connected to the hot melt module 3.

[0007] The working principle is as follows: during operation, the black and white PE cloth 1-1 of two rubber-plastic-cotton insulation blankets 1 are overlapped and laid flat, the automatic insulation blanket welding trolley is pressed on the joint of the two insulation blankets, the driving motor 2-4 adjusts the direction and speed of the trolley, and the lead screw motor 4-1 controls the reciprocating movement of the slider 4-3 by forward and reverse rotation so that the hot melt module 3 can accurately weld the overlapped black and white PE cloth, so that the two insulation blankets are welded together.

[0008] The beneficial effects of the present invention are as follows:

[0009] (1) Use machines instead of manual labor to save manpower.

[0010] (2) Compared with manual welding, machine welding maintains the same level of hot melt temperature, time, speed and other factors, with better welding quality and better application effect of thermal insulation after welding. It has simple structure, low cost and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
