DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example

[0020] In order to achieve the effect of air permeability and waterproofness of the foam tape, a bonding mechanism for the foam tape is designed. The specific scheme is as follows:

[0021] like Figure 1 As shown, a laminating mechanism for foam tape comprises a mounting plate 1, a conveying component 14, a guide component 10, a material tray 2 and a connecting component. A first feeding motor is provided at the rear of the material tray 2, and the connecting component is arranged below the material tray 2. A pressure roller is provided between the conveying component 14 and the material tray 2, and the connecting component can be moved between the pressure roller and the conveying component 14. A plurality of first loading positions are provided on the material tray 2, and the material roll can be replaced by circular rotation. A clamping member is also provided on the material tray 2 for clamping the front end of the material roll. A second loading position is also provided directly below the material tray 2, and a second feeding motor is connected to the rear of the second loading position. Guide wheels are provided between the material tray 2 and the foam loading position and the pressure roller. When one of the material rolls is used up, the material tray 2 can rotate automatically, and the front end of the new material roll is automatically pulled out to the pressure roller position for connection through the connecting component.

[0022] In this embodiment, three first loading positions are provided on the material tray 2, and a first loading position is set every 120° of the material tray 2360°. When the material tray 2 changes the material roll, it rotates 120° each time. Therefore, the first unloading motor at the rear of the material tray 2 adopts a servo motor to achieve precise control of the rotation angle. After the material tray 2 rotates 120°, the position of the material tray 2 is fixed and no longer rotates, and the material roll at the unloading position is opposite to the displacement hole 8 in the vertical direction.

[0023] When installing a new material roll, the staff needs to pull out the front end of the material roll, pass through the limit block 5, clamp it in the elastic clamp 6, and make the front end of the material strip exceed the elastic clamp 6 to facilitate clamping by the first connecting component.

[0024] Taking the bonding of foam and release film as an example, the upper part is used to place the release film roll, and the lower part is used to place the foam roll. A gluing component is also provided on the mounting plate 1, which is used to apply glue to the foam surface for subsequent bonding. The gluing component can adopt the existing gluing component, which is not drawn in the attached figure.

[0025] The mounting plate 1 is provided with a displacement hole 8 for displacement of the connecting component, and the displacement hole 8 extends to one end of the conveying direction of the pressure roller.

[0026] Specifically, the displacement hole 8 includes a portion located in the vertical direction and a portion in the horizontal direction, and is an L-shaped hole as a whole. The displacement hole 8 is provided to allow the rear connecting component to extend into the front side of the mounting plate 1 to ensure that the connecting component moves without interference.

[0027] Each first loading position is provided with an insertion rod 3 for inserting the material roll, and a movable pressing rod 4 is provided on one side of each first loading position for preventing the material roll from moving outward.

[0028] The setting of the pressure rod 4 can ensure that the release film material roll remains in the first loading position and will not move outward, preventing the material strip from deviating and affecting the fitting quality. A rotating shaft is provided at one end of the pressure rod 4, and the rotating shaft is installed on the material tray 2. The rotating shaft can rotate within a limited angle range on the material tray 2 to ensure that the pressure rod 4 will not swing at will. To install the material roll, insert the center insertion rod 3 of the material roll and use the pressure rod 4 to press the side of the material roll.

[0029] Each first feeding portion is provided with a avoiding opening at the shortest distance connecting the edge of the material tray 2, and the avoiding opening is provided with an elastic clamp 6 and a limiting block 5, and the front end of the elastic clamp 6 is a roller structure.

[0030] When the material roll is replaced on the material tray 2, the avoidance opening automatically rotates to align with the vertical displacement hole 8, and the first connecting component can move into the range of the material tray 2, clamp the front end of the material roll, and then pull it downward to extract it.

[0031] The connecting component includes a first connecting component in the longitudinal direction and a second connecting component in the horizontal direction. The first connecting component includes a first clamp and a first screw motor. The first clamp is slidably connected to the first screw motor. Both ends of the first screw motor are installed at the rear of the mounting plate 1. The second connecting component includes a second clamp, a rotating component and a second screw motor. The second clamp is installed at the output end of the rotating component. The rotating component is slidably connected to the second screw motor. Both ends of the second screw motor are installed at the rear of the mounting plate 1.

[0032] The pressing rollers include an upper pressing roller 12 and a lower pressing roller 13 . The upper pressing roller 12 is connected with a telescopic component to enable the upper pressing roller 12 to telescope up and down.

[0033] Both ends of the upper pressing roller 12 are connected with brackets, the top of the bracket is connected with a telescopic cylinder, and an elastic structure is provided between the bracket and the telescopic end of the telescopic cylinder. The telescopic cylinder controls the upper pressing roller 12 to extend and retract up and down, so that the upper pressing roller 12 can retract partly upward when in contact with the material, without causing excessive pressure to damage the surface of the product.

[0034] The guide component 10 includes a guide wheel and a telescopic drive. The guide component 10 is arranged on the side of the displacement hole 8 facing the conveying direction, and the guide component 10 is located at the intersection of the first connecting component and the second connecting component. The guide component 10 is inclined.

[0035] The conveying component 14 is a conveyor belt disposed opposite to each other up and down, and the conveying component 14 is disposed in the discharge direction of the mechanism.

[0036] The conveyor belts are driven by conveyor motors, which are installed at the rear of the mounting plate 1. The upper conveyor belt and the lower conveyor belt are driven by a conveyor motor respectively. The two conveyor motors are controlled in linkage to ensure that the upper conveyor belt and the lower conveyor belt have the same speed. Smooth pads are provided between the lower conveyor belt and the lower pressure roller 13 and inside the conveyor belt to keep the foam moving smoothly.

[0037] How it works:

[0038] When the previous material roll is almost used up, the tail of the material tape is clamped by the first connecting component. After the tail of the material tape is separated from the reel of the material roll, the material tape will not loosen, and as the bonding continues, the first connecting component gradually moves downward until it is horizontal, and then the tail of the material tape is clamped by the second connecting component, and then moves toward the pressure roller. When it is transferred to the pressure roller, the upper pressure roller 12 rises to avoid the second connecting component to facilitate its passage. When the bonding part is closer to the tail of the material tape, the second connecting component releases the material tape, and the mechanism stops running until the new material tape is pulled to this position. In this process, when the tail block of the material tape is transferred to the water In the horizontal direction, the guide component 10 is in a retracted state and moves back to the bottom of the first connecting component 7, and the first connecting component clamps the front end of the material tape of the new material roll and moves downward to the position of the second connecting component. After being clamped by the second connecting component, it is pulled in the direction of the pressure roller, and the guide component 10 is extended to ensure the tension of the material tape. At the same time, the clamping jaws of the second connecting component are rotated from vertical to horizontal. After the second connecting component passes the pressure roller, the upper pressure roller 12 presses down, and the second connecting component rotates the clamping jaws to make the front end of the material tape bonded to the foam surface. Subsequently, the bonding station will perform secondary processing on this position to ensure good bonding.

[0039] The bonding mechanism of the present scheme is provided with a plurality of first loading positions for material rolls on the material tray 2, on which a plurality of material rolls can be placed at the same time, and the material tray 2 can automatically rotate a new material roll to the unwinding position, and through the connecting component, the front end of the material roll can be pulled to the bonding position, so as to realize fast material replacement and head-to-tail connection, thereby improving the operation efficiency, and when the equipment is running, the staff can place a new material roll on the vacant first loading position. Example

[0040] In this embodiment, the structure of the bonding mechanism is basically the same as that of Example 1, with the difference that the position below for placing the foam material roll adopts the same structure as the material tray 2, and is provided with a third connecting component for connecting the foam material roll. After the previous foam material roll is used up, the foam material roll is automatically replaced and pulled to the bonding position.

[0041] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
