Description

Technical Field

[0001] The utility model relates to wrench processing equipment, in particular to a plastic tray strip assembly device. Background Art

[0002] A wrench is a commonly used installation and disassembly tool, a manual tool that uses the lever principle to turn bolts, screws, and nuts; usually, openings or socket holes for clamping bolts or nuts are made at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction, and the bolt or nut can be turned; wrenches are usually made of carbon structural steel or alloy structural steel.

[0003] When sold and stored, several wrenches are respectively placed in a tray. To prevent the wrenches from disengaging from the corresponding positions during handling or transportation, usually before leaving the factory, the wrenches in the corresponding positions are further limited by a penetrating strip. When the strip penetrates into the last slot position, since the width of the front end of the strip is greater than the insertion opening of the last slot position, it is necessary to preheat the end of the strip manually and then insert it. This method not only has low efficiency but also requires the assistance of multiple people. Summary of the Utility Model

[0004] The utility model aims at the above problems and provides a plastic tray strip assembly device with a compact structure, simple and efficient operation.

[0031] The following refers to Figures 1-4 describe the present utility model;

[0032] A plastic pallet batten assembling device, comprising:

[0033] A workbench 100, the top surface of which is provided with a limiting part 110 adapted to the pallet 400; several heating holes 120 corresponding to the heating areas of the battens 500 are arranged in the limiting part 110;

[0034] A hot air pipe 300, fixedly arranged at the bottom surface of the workbench 100; comprising an air inlet and several air outlets; the air inlet is adapted to the air blowing port of the hot air gun 200; the air outlets are hermetically and fixedly connected to the heating holes 120, and the number thereof is equal to the number of the heating holes 120 and corresponds one by one; the hot air entering through the air inlet flows onto the battens 500 at several air outlets, and simultaneously heats several battens 500 synchronously, improving the packaging efficiency;

[0035] The thermal expansion mechanism is arranged below the workbench 100. Through the thermal expansion mechanism, the hot air gun 200 is docked with the air inlet, that is, the hot air gun 200 can be arranged below the workbench 100 in a liftable manner through the expansion mechanism. The start of the hot air gun 200 in this case is realized by stepping on an external foot switch, which improves the convenience of the operator to start the hot air gun 200. Each time the foot switch is stepped on, the hot air gun 200 is controlled by a relay for the heating time (the time is adjustable) to ensure that the tray 400 will not melt due to excessive temperature or the pressure strip 500 cannot be assembled due to insufficient temperature; both the tray 400 and the pressure strip 500 in this case are made of plastic PP material.

[0036] The expansion mechanism includes a spring 210;

[0037] The spring 210 is arranged vertically and is arranged at the bottom of the hot air gun 200. Through the vertical expansion and contraction of the spring 210, the air outlet of the hot air gun 200 is installed on the air inlet of the hot air pipe 300, that is, the detachable connection between the hot air gun 200 and the hot light pipe 300 is realized.

[0038] The height of the spring 210 is adjusted through a limit mechanism 600; the limit mechanism 600 includes:

[0039] A limit adjustment rod 610 is vertically and adjustably fixed on the support frame for supporting the workbench 100 through threads;

[0040] A support plate 620 is detachably and fixedly arranged on the top of the limit adjustment rod 610; the spring 210 is sleeved on the limit adjustment rod 610. By raising or pressing down the support plate 620, the height of the spring 210 is controlled to meet the height installation requirements of the hot air gun 200.

[0041] The limit adjustment rod 610 rotates through threads to control the height adjustment of the support plate 620. After leaving a gap between the support plate 620 and the air inlet, by pressing down the top surface of the support plate 620 with the tail of the hot air gun 200, the gap between the support plate 620 and the air inlet is increased. After the air outlet of the hot air gun 200 is clamped into the air inlet, through the elastic force of the spring 210 resetting, the hot air gun 200 is fixed between the support plate 620 and the air inlet. When removing the hot air gun 200, directly press down the support plate 620. The installation and disassembly are simple and convenient, improving the maintenance and replacement efficiency.

[0042] The expansion mechanism includes a cylinder, an oil cylinder or an electric push rod.

[0043] If a cylinder is adopted, the cylinder is arranged vertically, the cylinder body is detachably and fixedly connected with the support frame, the piston rod extends upward, and the end of the piston rod is detachably and fixedly connected with the tail of the hot air gun 200. The height of the hot air gun 200 is controlled by the expansion and contraction of the piston rod.

[0044] The limiting part 110 includes a plurality of limiting pieces 111 adapted to the edge of the tray 400;

[0045] The limiting piece 111 is fixedly arranged on the workbench 100.

[0046] The number of the limiting pieces 111 is not less than two. In this case, four are selected and are adapted to the four-corner edges of the tray 400.

[0047] The operation steps of this case are as follows:

[0048] Step 1: As Figure 1 shown, load the hot air gun 200 between the spring 210 and the hot air pipe 300;

[0049] Step 2: As Figure 2 shown, place the tray 400 into the limiting part 110;

[0050] Step 3: The starting end ( Figure 4 bottom end) of the pressing strip 500 penetrates from the end hole position ( Figure 4 top position) of the tray 400, and the wrench is limited in the corresponding installation position; when the starting end of the pressing strip 500 enters the last card slot position (the card slot position near the bottom of the tray 400), the bayonet is smaller than the starting end of the pressing strip 500 and cannot enter the last card slot position; there is a notch on the tray 400 adapted to the last card slot position. Start the hot air gun 200 to heat the starting end of the pressing strip 500 at the last card slot position. After the starting end of the pressing strip 500 is softened, snap the pressing strip 500 into the last card slot position. After natural cooling, the barbs ( Figure 4 area A in) of the starting end of the pressing strip 500 lock the pressing strip 500.
