Description

Technical Field

[0001] This utility model relates to a plastic bag stapler, belonging to the field of plastic bag hot pressing technology. Background Technology

[0002] In the field of plastic bag production and packaging, traditional processes require cutting plastic bags to be bundled into fixed quantities for subsequent packaging and storage. Current technology primarily relies on manual labor to take a fixed number of plastic bags and stack them on a thermoforming machine, where they are then heat-pressed into stacks before packaging.

[0003] During the hot-pressing process, plastic bags need to be fitted onto positioning posts through pre-set holes for hot pressing. After hot pressing, the compressed, stacked plastic bags are removed from the positioning posts for packaging. However, due to the excessively small gap between the plastic bags and the positioning posts, significant frictional resistance is generated between the plastic bags and the post surfaces. This overly tight fit requires operators to apply additional peeling force when removing the plastic bags after hot pressing, which not only reduces operational efficiency but may also damage the plastic bags due to improper force, affecting production continuity and product quality.

[0004] Therefore, there is a need for a plastic bag stapler that can easily handle the heat-pressed plastic bags and improve work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic bag nailing machine to solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by this utility model is as follows: A plastic bag stapler, comprising a frame, wherein a pressing mechanism and a telescopic positioning mechanism are provided on the frame;

[0007] The pressing mechanism includes a second drive cylinder assembly and a pressing assembly; the cylinder body of the second drive cylinder assembly is fixed to the second cylinder mounting plate, and the piston rod of the second drive cylinder assembly is connected to the pressing assembly in a transmission manner; the pressing assembly includes a heating rod and a pressure plate, the heating rod is disposed below the second drive cylinder assembly, the pressure plate is disposed below the heating rod, and the pressure plate has an upper positioning hole.

[0008] The telescopic positioning mechanism is located below the pressing mechanism. The telescopic positioning mechanism includes a support plate, a positioning column, a positioning mounting base, and a third drive cylinder assembly. The positioning column is fixed on the positioning mounting base. The third drive cylinder is fixed on the frame. The third drive cylinder assembly is connected to the positioning mounting base through a third cylinder connecting plate and is used to drive the positioning column to move up and down. A heating needle is fixedly connected below the heating rod. Both the pressure plate and the support plate are provided with heat-piercing holes for the heating needle to pass through.

[0009] The frame includes a front mounting plate, the tray is fixedly connected to the front mounting plate, and the tray has a lower positioning hole; the tray is located above the positioning mounting base, and the lower positioning hole is sleeved on the positioning post.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: the temperature of the heating rod is conducted to the hot-pressing needle to heat the plastic bag, thereby melting the hot-pressed area of ​​the plastic bag and causing the plastic bag to fuse and stick together; the plastic bag is placed on the positioning column and placed on the pallet. After the equipment is started, the third drive cylinder assembly drives the positioning column to move downward until it is completely under the pallet. The hot-pressed plastic bag is detached from the positioning column. At this time, the operator can remove the plastic bag without additional peeling. After a certain period of time, the positioning column resets, and the next round of hot pressing operation can be carried out, which improves production efficiency.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the piston rod of the second drive cylinder assembly is connected to the pressing assembly via the second cylinder connecting plate, the heating rod is fixed below the second cylinder connecting plate, and the second cylinder connecting plate is connected to the pressure plate via the telescopic positioning assembly.

[0013] The beneficial effects of adopting the above-mentioned further solution are that, in the pressing state, the telescopic positioning component provides stability, allowing the upper positioning hole on the pressure plate to pass through the positioning post smoothly to complete the pressing after pressing; and when pressing down, the setting of the telescopic positioning component can prevent the pressure plate and the heating rod from contacting each other, avoiding the melting of the plastic bag surface and affecting normal use.

[0014] Furthermore, a third guide rail is also provided on the front mounting plate; an L-shaped positioning connecting plate is slidably connected to the third guide rail; the L-shaped positioning connecting plate is also connected to the positioning mounting base.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the L-shaped positioning connecting plates fixed on both sides of the positioning mounting base support and fix it, thereby improving the stability of the positioning column.

[0016] Furthermore, the front, back, and top of the heating rod are all covered with insulation boards.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it protects the heating rod and prevents operators from accidentally touching the overheated heating rod and getting burned.

[0018] Furthermore, the frame also includes an upper cover plate, and a reset groove is provided on the upper cover plate and the front mounting plate of the frame;

[0019] The upper cover plate is provided with an ejection mechanism for ejecting the pressing mechanism from the reset groove; the ejection mechanism includes a first drive cylinder assembly, the first drive cylinder assembly is provided with first guide rails on both sides, the transmission connecting plate is mounted on the first guide rails, and the first drive cylinder assembly is connected to the second cylinder mounting plate through the transmission connecting plate.

[0020] Furthermore, in operation, the pressing mechanism extends out of the reset groove to heat-press the plastic bag; in the reset state, the pressing mechanism is located inside the reset groove, and the insulation plate of the pressing mechanism does not exceed the boundary of the front mounting plate.

[0021] The beneficial effects of adopting the above-mentioned further solution are that, in operation, the ejection mechanism pushes the pressing mechanism out of the reset groove, and then the pressing mechanism presses down. After pressing is completed, the pressing mechanism resets. In the reset state, the pressing mechanism returns to the reset groove, and the operator can remove the plastic bag from the tray without being hindered by the pressing mechanism, and the probability of touching the heating rod is reduced.

[0022] Furthermore, an inverted L-shaped placement plate is provided above the tray.

[0023] The advantage of adopting the above-mentioned further solution is that the turning point of the inverted L-shaped placement board is a smooth rounded corner, which reduces the risk of scratching the plastic bag.

[0024] Furthermore, a solenoid valve is provided on the side of the frame, and the first drive cylinder assembly, the second drive cylinder assembly, and the third drive cylinder assembly are respectively connected to the solenoid valve.

[0025] Furthermore, the plastic bag nailing machine is electrically connected to a pressing switch.

[0026] The beneficial effect of adopting the above-mentioned further solution is that the solenoid valve is controlled by the instantaneous trigger signal of the pressing switch, and each drive cylinder is controlled by an independent solenoid valve. The timing of the action can be adjusted individually through time-sharing control, thereby optimizing the coordination of the action. The pressing switch triggers a signal after the locking action is completed, forcing the machine to reset to the initial position and preventing continuous false triggering.

[0027] Furthermore, a temperature controller is installed on the side wall of the frame to control the temperature of the heating rod. Attached Figure Description

The first drive cylinder assembly 201 is connected to the second cylinder mounting plate 302 of the pressing mechanism 3 through the transmission connecting plate 202.

[0047] The pressing mechanism 3 includes a second drive cylinder assembly 301 and a pressing assembly 303. The cylinder body of the second drive cylinder assembly 301 is fixed on the second cylinder mounting plate 302. The piston rod of the second drive cylinder assembly 301 is fixedly connected to the pressing assembly 303 via a second cylinder connecting plate 3031. The pressing assembly 303 includes a heating rod 3032 and a pressure plate 3035. The heating rod 3032 is fixed below the second cylinder connecting plate 3031. The front, rear, and upper parts of the heating rod 3032 are covered with insulation plates 3034 to isolate the heating rod 3032 and prevent operators from accidentally touching the heating rod 3032 and being burned. The pressure plate 3035 is located below the heating rod 3032. The second cylinder connecting plate 3031 is connected to the pressure plate 3035 via a telescopic positioning assembly 3037. The pressure plate 3035 has an upper positioning hole 3036 for the positioning post 403 to pass through.

[0048] The telescopic positioning mechanism 4 is located below the pressing mechanism 3. The telescopic positioning mechanism 4 includes a support plate 401, a positioning column 403, a positioning mounting base 404, and a third drive cylinder assembly 405. The positioning column 403 is fixed on the positioning mounting base 404. The third drive cylinder is fixed on the front mounting plate 101 of the frame 1. The third drive cylinder assembly 405 is connected to the positioning mounting base 404 through a third cylinder connecting plate 406 and is used to drive the positioning column 403 to move up and down.

[0049] The tray 401 is fixedly connected to the side plate and the front mounting plate 101. The tray 401 has a lower positioning hole 409. The tray 401 and the inverted L-shaped placement plate 402 are arranged in sequence above the positioning mounting base 404.

At the same time, the heating rod 3032 moves down. The square hot-pressing needle 3033 passes through the hot-pressing hole of the pressure plate 3035 and the support plate 401 to complete the hot-pressing; after the hot pressing is completed, the second drive cylinder assembly 301 retracts, and the pressing mechanism 3 resets to the reset groove; the third drive cylinder assembly 405 then drives the positioning mounting seat 404 to move the positioning column 403 down to below the support plate 401, and the plastic bag naturally detaches from the positioning column 403, allowing the operator to move it horizontally to pick up the material; the smooth rounded corners of the inverted L-shaped placement plate 402 prevent the plastic bag from being scratched, and the heat preservation plate 3034 covers the heating rod 3032 to prevent the operator from being burned; after picking up the material, the positioning column 403 automatically resets to the initial height, and the pressing mechanism 3 remains in the storage state, waiting for the next trigger of the pressing switch to start a new cycle.
