Description

Technical Field

[0001] The utility model relates to the technical field of bonding machines, and particularly relates to a bonding machine adaptable to EVA. Background Art

[0002] Existing packaging lining materials generally include pearl cotton, EVA, etc. Since the melting point of pearl cotton is low, the bonding work of pearl cotton is generally carried out by a bonding machine. However, due to the relatively low power of the hot melt table of the existing bonding machine, the highest temperature is only about 250°C, while the melting point temperature of EVA is about 330°C. Therefore, the existing EVA packaging lining is generally bonded by glue, but the glue bonding method is relatively inefficient. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bonding machine adaptable to EVA. By arranging a detachable high-temperature hot melt table above the existing hot melt table, hot melt bonding work can also be carried out on EVA materials, and the production efficiency of EVA linings can be improved.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A bonding machine adaptable to EVA includes a housing. A high-temperature hot melt table and a medium-temperature hot melt table are arranged up and down in the middle of the housing. A high-power electric heating device is arranged in the high-temperature hot melt table, and the material of the high-temperature hot melt table is steel. A relatively lower-power electric heating device is arranged in the medium-temperature hot melt table, and the material of the medium-temperature hot melt table is generally aluminum. The medium-temperature hot melt table is fixed on a support frame in the middle of the housing, and the high-temperature hot melt table is detachably connected to the support frame;

[0006] A notch is formed at each of the left end and the right end of the housing, and a movable workbench is arranged in each notch;

[0007] A needle plate that can move left and right and can be lifted is arranged above the two workbenches.

[0008] Lay one end of workpiece 1 flat on the workbench, place workpiece 2 at an appropriate position on workpiece 1, and then the workbench moves towards the middle. Then, the needle plate moves above workpiece 2, and the needle plate moves down to grab workpiece 2. Then, after the needle plate returns above the hot melt table, it moves down to attach workpiece 2 to the hot melt table, and the lower end of workpiece 2 is melted by the hot melt table. Then the needle plate quickly sends workpiece 2 back to its original position on workpiece 1 again, and the melted part of workpiece 2 can be bonded to workpiece 1 together.

[0009] When it is necessary to bond lining materials with a higher melting point such as EVA, a high-temperature hot melt table is used; when it is necessary to bond lining materials with a relatively low melting point such as pearl cotton, the high-temperature hot melt table is removed from the medium-temperature hot melt table, and the pearl cotton and other lining materials are hot-melted through the medium-temperature hot melt table.

[0010] By setting up two workbenches, two people can work continuously at intervals, which can improve the bonding efficiency and the utilization rate of the equipment.

[0011] The utility model is further configured that a heat insulating pad is sandwiched between the high-temperature hot-melt table and the medium-temperature hot-melt table.

[0012] The heat insulation pad can transfer heat to the medium-temperature hot melt table when using a high-temperature hot melt table, thereby reducing energy consumption; at the same time, it can protect the medium-temperature hot melt table and prevent it from being bumped or damaged.

[0013] The utility model is further configured as follows: a support shaft extending in the front-rear direction is fixed to the inner end and the middle part of the workbench, and the support shaft passes through the protruding end of the workbench and is connected to a roller; the roller is inserted into the waist-shaped groove on the shell;

[0014] A push-pull plate is fixed at the bottom of the workbench, the push-pull plate is fixed to the end of the telescopic rod of the first electric telescopic cylinder, the first electric telescopic cylinder is fixed on the support frame, and the first electric telescopic cylinder is electrically connected to a controller.

[0015] The first electric telescopic cylinder drives the push-pull plate to move, and the push-pull plate drives the workbench to move outward or inward. The roller can reduce the resistance of the push-pull plate, and the waist-shaped groove can guide the movement of the roller and limit the movement range. The controller controls the extension amount of the telescopic rod of the first electric telescopic cylinder to determine the position of the workbench.

[0016] The utility model is further configured as follows: a positioning block is provided on the workbench, and the positioning block can position the placed workpieces 1 and 2 to ensure the position accuracy of the workpiece placement.

[0017] The utility model is further configured as follows: an extended channel is fixed at the outer end of the notch; the extended channel can be used to receive the workbench when it moves outward, prevent the workbench from falling, reduce safety hazards, and support the redundant part of the workpiece 1;

[0018] The outer end of the extended channel is formed with an arc portion, which can increase the dragging smoothness when the workbench moves to drag the workpiece 1 and prevent the workpiece 1 from getting stuck or being pulled apart.

[0019] The utility model is further configured as follows: a smoke extraction pipe is provided on the top of the shell. When bonding lining materials with a relatively high melting point such as EVA, smoke will be generated due to the high hot melting temperature. The generated smoke can be extracted through the smoke extraction pipe to ensure a normal working environment.

[0020] The utility model is further configured as follows: the needle plate includes a substrate and a plurality of vertically arranged pins fixed to the bottom of the substrate;

[0021] A plurality of cylinders are fixed on the substrate, and the piston rods of the cylinders are fixed on a lifting plate located below the substrate; the pins pass through the lifting plate;

[0022] The lifting plate is fixed to the end of the telescopic rod of a vertically arranged second electric telescopic cylinder, and the second electric telescopic cylinder is fixed on a sliding seat. The sliding seat is slidably connected to a rack and a guide rod arranged in the left - right direction, and the rack and the guide rod are fixed in the shell; a motor is fixed on the sliding seat, and a gear is fixed on the motor shaft of the motor. The gear meshes with the rack. The second electric telescopic cylinder and the motor are both electrically connected to a controller, and the controller controls the cylinders.

[0023] Through the above - mentioned technical solution, when the motor rotates, it drives the gear to rotate. Since the rack is stationary, the gear reacts on the motor, and the motor drives the sliding seat to move left or right along the guide rod. The sliding seat drives the lifting plate to move through the second electric telescopic cylinder, thereby driving the needle plate to move; the telescopic rod of the second electric telescopic cylinder can drive the lifting plate to move up and down, thereby realizing the lifting of the needle plate; the cylinders can drive the substrate to move up or down relative to the lifting plate, thereby realizing inserting the pins into the workpiece 2 or pulling the pins out of the workpiece 2.

[0024] The prominent effect of the utility model is:

[0025] Compared with the prior art, by arranging a detachable high - temperature hot - melting table above the existing hot - melting table, hot - melting bonding work can be carried out on EVA materials, which can improve the production efficiency of EVA linings; at the same time, it can also be adapted to the bonding work of low - melting - point lining materials such as pearl cotton;

[0026] The workpiece can be conveniently and stably grabbed through the pins, and the pins can be conveniently separated from the workpiece by driving the pins through the cylinders. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0040] The following references Figures 1 to 4 to illustrate the embodiments of the present utility model:

[0041] An adhesive machine adaptable to EVA, as Figure 1 shown, includes a housing 10. A high-temperature hot melt table 20 and a medium-temperature hot melt table 30 are arranged up and down in the middle of the housing 10. The high-temperature hot melt table is provided with a high-power electric heating device inside, and the material of the high-temperature hot melt table is steel; the medium-temperature hot melt table is provided with a relatively low-power electric heating device inside, and the material of the medium-temperature hot melt table is generally aluminum. The medium-temperature hot melt table 30 is fixed on a support frame 101 in the middle of the housing 10, and the high-temperature hot melt table 20 is detachably connected to the support frame 101;

[0042] A notch 102 is formed at each of the left end and the right end of the housing 10, and a movable workbench 40 is arranged in each notch 102;

[0043] Above the two workbenches 40, there is a needle plate 50 that can move left and right and can be lifted.

[0044] Lay one end of workpiece 1 flat on the workbench, place workpiece 2 at an appropriate position on workpiece 1, and then the workbench 40 moves towards the middle; then, the needle plate moves above workpiece 2, and the needle plate moves down to grasp workpiece 2; then, after the needle plate returns above the hot melt table, it moves down to attach workpiece 2 to the hot melt table, and the lower end of workpiece 2 is melted through the hot melt table; then the needle plate quickly sends workpiece 2 back to its original position on workpiece 1 again, and the melted part of workpiece 2 can be bonded to workpiece 1 together.

[0045] When bonding inner lining materials with relatively high melting points such as EVA, use a high-temperature hot melt table; when bonding inner lining materials with relatively low melting points such as pearl cotton, remove the high-temperature hot melt table from the medium-temperature hot melt table, so as to carry out hot melting of inner lining materials such as pearl cotton through the medium-temperature hot melt table.

[0046] By setting two workbenches, two people can work continuously at intervals, which can improve the bonding efficiency and also improve the utilization rate of the equipment.

[0047] As Figure 4 shown, a heat insulation pad 60 is clamped between the high-temperature hot melt table 20 and the medium-temperature hot melt table 30 of this embodiment.

[0048] Through the heat insulation pad, heat can be transferred to the medium-temperature hot melt table when using the high-temperature hot melt table, reducing energy consumption; at the same time, it can protect the medium-temperature hot melt table and prevent it from being bruised.

[0049] As Figure 3 shown, a support shaft 41 extending in the front-rear direction is fixed at each of the inner end and the middle part of the workbench 40 of this embodiment. The support shaft 41 passes through the protruding end of the workbench 40 and is connected with a roller 42; the roller 42 is inserted into a waist-shaped groove 103 on the housing 10;

[0050] A push-pull plate 43 is fixed at the bottom of the workbench 40. The push-pull plate 43 is fixed at the end of the telescopic rod of a first electric telescopic cylinder 44, and the first electric telescopic cylinder 44 is fixed on the support frame 101. The first electric telescopic cylinder is electrically connected to a controller.

[0051] The first electric telescopic cylinder drives the push-pull plate to move, and the push-pull plate drives the workbench to move outwards or inwards. The roller can reduce the resistance of the push-pull plate to move, and at the same time, the waist-shaped groove can guide the movement of the roller and limit the movement amplitude. By controlling the telescopic amount of the telescopic rod of the first electric telescopic cylinder through the controller, the moving position of the workbench can be determined.

[0052] As Figure 4 shown, a positioning block 45 is provided on the workbench 40. The positioning block can position the placed workpiece 1 and workpiece 2 to ensure the accuracy of the placement position of the workpiece.

[0053] As Figure 1 、 Figure 4As shown, an extended channel 46 is fixed at the outer end of the notch 102; the extended channel can be used to receive the workbench when it moves outward, prevent the workbench from falling, reduce safety hazards, and support the excess part of the workpiece 1;

[0054] The outer end of the extended channel 46 is formed with an arc portion 47, which can increase the dragging smoothness when the workbench moves to drag the workpiece 1, thereby preventing the workpiece 1 from getting stuck or being pulled apart.

[0055] like Figure 1 As shown, a smoke extraction pipe 70 is provided on the top of the shell 10. When bonding lining materials with a high melting point such as EVA, smoke will be generated due to the high hot melting temperature. The generated smoke can be extracted through the smoke extraction pipe to ensure a normal working environment.

[0056] like Figure 2 As shown, the needle board 50 includes a base plate 501 and a plurality of vertically arranged pins 502 fixed to the bottom of the base plate 501;

[0057] A plurality of cylinders 503 are fixed on the base plate 501, and piston rods of the cylinders 503 are fixed on a lifting plate 504 located below the base plate 501; the pins 502 pass through the lifting plate 504;

[0058] The lifting plate 504 is fixed to the end of the telescopic rod of the second electric telescopic cylinder 505 which is arranged vertically. The second electric telescopic cylinder 505 is fixed to the sliding seat 506. The sliding seat 506 is slidably connected to the rack 507 and the guide rod 508 which are arranged in the left and right directions. The rack 507 and the guide rod 508 are fixed in the housing 10. The sliding seat 506 is fixed with a motor 509. The motor shaft of the motor 509 is fixed with a gear 510 which meshes with the rack 507. The second electric telescopic cylinder and the motor are both electrically connected to the controller, and the controller controls the cylinder.

[0059] Through the above technical solution, the rotation of the motor drives the gear to rotate. Since the rack is stationary, the gear reacts to the motor, and the motor drives the sliding seat to move left or right along the guide rod. The sliding seat drives the lifting plate to move through the second electric telescopic cylinder, thereby driving the needle plate to move; the telescopic rod of the second electric telescopic cylinder can drive the lifting plate to move up and down, thereby realizing the lifting and lowering of the needle plate; the cylinder can drive the base plate to move up or down relative to the lifting plate, thereby realizing the insertion of the pin into the workpiece 2 or the removal of the pin from the workpiece 2.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
