Description

Technical Field

[0001] This utility model relates to the field of electric heating cloth manufacturing technology, and in particular to a cloth feeding and attaching device. Background Technology

[0002] The electric heating cloth mainly consists of a blank cloth, a top cloth, and a heat-conducting layer structure between the two. The manufacturing process involves a conveyor belt carrying the blank cloth flowing between various stations. During this flow, flexible circuit boards, TPU films, and carbon films are laid on the blank cloth to form a blank cloth assembly with a heat-conducting layer structure. Subsequently, the top cloth is directly attached to the blank cloth assembly, and the two continue to flow together on the conveyor belt until they are conveyed to the hot pressing mold for hot pressing molding process, finally producing the finished electric heating cloth.

[0003] However, when the upper fabric is directly attached to the lower fabric assembly, during the conveyor belt transport process, the TPU film in the heat-conducting layer structure itself lacks an effective fixing effect on the upper fabric. At the same time, the conveyor belt speed is not constant, so the upper fabric is easily disturbed by factors such as changes in the conveyor belt speed, resulting in positional displacement, which seriously affects the finished quality of the electric heating fabric. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a feeding and attaching device for fabric, which effectively solves the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a fabric feeding and attaching device, comprising:

[0006] The conveyor belt carries several fabric assemblies.

[0007] The feeding assembly for the feeding fabric includes a feeding component and a peeling component. The feeding component is used to unwind the release paper carrying the feeding fabric, and the peeling component is used to peel the feeding fabric off the release paper.

[0008] A transport assembly includes an adsorption head and a linear conveying assembly, wherein the adsorption head moves along the linear conveying assembly to transport a stripped feed fabric onto a feed fabric assembly on the conveyor belt.

[0009] A material feeding platform is provided below the conveyor belt, and a preheating plate is provided at the attachment position of the feeding cloth on the material feeding platform.

[0010] Furthermore, the feeding assembly includes a feeding frame, and a feeding roller and a guiding roller disposed on the feeding frame;

[0011] The release layer, after being unwound from the unwinding roller, enters the peeling assembly via the guide roller.

[0012] Furthermore, the paper guide roller is equipped with a drive motor.

[0013] Furthermore, the stripping assembly includes a support frame, and a pressing assembly and a stripping assembly sequentially arranged on the support frame along the unwinding direction;

[0014] A take-up roller assembly is provided below the peeling assembly. The take-up roller assembly is used to take up the peeled release paper, and the take-up direction of the take-up roller assembly is opposite to the unwinding direction of the unwinding assembly.

[0015] Furthermore, the support frame includes a base plate, a middle plate, and a vertical plate; the middle plate is arranged parallel to the base plate, and the vertical plate is arranged on one side of the base plate and the middle plate along the unwinding direction;

[0016] The pressing assembly and the peeling assembly are disposed above the middle plate, and the winding roller assembly is disposed on the vertical plate between the bottom plate and the middle plate.

[0017] Furthermore, the pressing assembly includes:

[0018] Adsorption plate;

[0019] Two flattening rollers are respectively installed at the feed end and the discharge end of the adsorption plate;

[0020] A pressing assembly, disposed above the adsorption plate, includes a gantry frame, a pressure plate, and a downward pressing drive component. The downward pressing drive component is fixed to the gantry frame, and the pressure plate is disposed at the driving end of the downward pressing drive component.

[0021] The pressure plate presses the unwound release paper as it moves toward the adsorption plate.

[0022] Furthermore, the bottom surface of the pressing plate facing the adsorption plate is provided with multiple pressing blocks.

[0023] Furthermore, the stripping assembly includes a stripping plate, a pre-stripping platform, and a stripping drive component;

[0024] The stripping drive unit supports and drives the stripping plate to move between the pre-stripping platform and the pressing assembly in a direction parallel to the unwinding direction.

[0025] Furthermore, it also includes a visual positioning component, which includes a first camera disposed on the conveyor belt and a second camera disposed on the transport path of the transport component.

[0026] Furthermore, the conveying assembly also includes an R-axis assembly; the R-axis assembly is disposed in the linear conveying assembly and is used to drive the adsorption head to rotate along a vertical line.

[0027] The beneficial effects of this invention are as follows: By using a preheating plate, the TPU film within the fabric assembly is preheated, thereby increasing the adhesion between the upper and lower fabric assemblies. This effectively reduces the positional shift of the upper fabric caused by factors such as changes in conveyor belt speed, thus improving the finished quality of the electrically heated fabric. Furthermore, the initial heating between the upper and lower fabric assemblies reduces the processing time required for final hot pressing, thereby shortening the entire production cycle and improving production efficiency.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] like Figures 1 to 7 The fabric feeding and attaching device shown includes: a conveyor belt 1, a fabric feeding assembly 2, and a conveying assembly 3. The conveyor belt 1 carries several fabric feeding assemblies.

[0038] The feeding assembly 2 includes a feeding assembly 21 and a peeling assembly 22. The feeding assembly 21 is used to unwind the release paper carrying the feeding cloth, and the peeling assembly 22 is used to peel the feeding cloth off the release paper.

[0039] The conveying assembly 3 includes an adsorption head 31 and a linear conveying assembly 32. The adsorption head 31 moves along the linear conveying assembly 32 to convey the stripped feed fabric to the unloaded fabric assembly on the conveyor belt 1.

[0040] Among them, a feeding platform 4 is set below the conveyor belt 1, and a preheating plate 4a is provided at the attachment position of the feeding cloth on the feeding platform 4.

[0041] This invention, through the preheating plate 4a, preheats the TPU film within the fabric assembly, thereby increasing the adhesion between the upper and lower fabric assemblies. This effectively reduces the positional shift of the upper fabric caused by factors such as changes in conveyor belt speed 1, improving the finished quality of the electrically heated fabric. Furthermore, the initial heating between the upper and lower fabric assemblies reduces the processing time required for final hot pressing, thus shortening the overall production cycle and increasing production efficiency.

[0042] In this invention, the unloading assembly 21 includes an unloading frame 211, and a paper unloading roller 212 and a paper guide roller 213 disposed on the unloading frame 211. The release layer unwound on the paper unloading roller 212 enters the peeling assembly 22 via the paper guide roller 213. The paper guide roller 213 can adjust the travel direction and tension of the release layer to ensure that the release layer remains flat and has uniform tension before entering the peeling assembly 22.

[0043] Based on the above scheme, the guide roller 213 is equipped with a drive motor 213a. The drive motor 213a can precisely control the transmission speed and tension of the release layer, and adjust the speed according to production needs to ensure that the release layer maintains uniform tension and stable speed during transmission. This is crucial for ensuring the processing effect of the release layer in the peeling assembly 22. In addition, a feed guide plate 23 is set at the feed inlet of the peeling assembly 22 to guide the release layer into the peeling assembly 22 along the correct path, reducing the deviation or wrinkling of the release layer during the feeding process.

[0044] In a preferred embodiment of this utility model, the peeling component 22 includes a support frame 221, and a pressing component 222 and a peeling component 223 sequentially arranged on the support frame 221 along the unwinding direction;

[0045] Below the peeling assembly 22, a take-up roller assembly 224 is provided. The take-up roller assembly 224 is used to wind up the peeled release paper. During the process, the pressing assembly 222 presses the release paper, while the take-up roller assembly 224 winds up the peeled release paper. The winding tension of the take-up roller assembly 224 is used to control the tension of the release paper at the peeling position, ensuring that the release paper can be smoothly separated from the feed cloth. In addition, the winding direction of the take-up roller assembly 224 is opposite to the unwinding direction of the unwinding assembly 21. This not only effectively manages the peeled release paper and prevents it from scattering and causing chaos on the production site, but also ensures that the release paper remains flat during the winding process, facilitating subsequent processing or recycling.

[0046] like Figure 5 As shown, the support frame 221 includes a base plate 221a, a middle plate 221b, and a vertical plate 221c; the middle plate 221b is arranged parallel to the base plate 221a, and the vertical plate 221c is arranged on one side of the base plate 221a and the middle plate 221b along the unwinding direction; the pressing assembly 222 and the peeling assembly 22 are arranged above the middle plate 221b, and the winding roller assembly 224 is arranged on the vertical plate 221c between the base plate 221a and the middle plate 221b. The layered design can effectively distribute the force and reduce structural deformation or damage caused by excessive local stress.

[0047] In a preferred embodiment, the pressing assembly 222 includes: an adsorption plate 222a, two flattening rollers 222e, and a pressing assembly. The two flattening rollers 222e are respectively disposed at the feed end and the discharge end of the adsorption plate 222a. The pressing assembly is disposed above the adsorption plate 222a and includes a gantry frame 222b, a pressing plate 222c, and a downward pressing drive 222d. The downward pressing drive 222d is fixed on the gantry frame 222b, and the pressing plate 222c is disposed at the drive end of the downward pressing drive 222d. The pressing plate 222c presses the unwound release paper as it moves toward the adsorption plate 222a. The two flattening rollers 222e, respectively disposed at the feed end and the discharge end of the adsorption plate 222a, can effectively flatten the release paper, reducing wrinkles or twists in the release paper before entering the adsorption plate 222a and after leaving the adsorption plate 222a. This helps ensure that the release paper remains flat during the peeling process, improving the peeling quality. The release paper is subjected to a stable clamping force by the pressure drive 222d and the pressure plate 222c, which reduces the possible slippage or displacement during the peeling process. The stable clamping force helps to improve the accuracy and consistency of peeling.

[0048] In a further optimized embodiment, the bottom surface of the pressure plate 222c facing the adsorption plate 222a is provided with multiple pressure blocks. These pressure blocks distribute the pressure applied by the pressure plate 222c to multiple small areas, resulting in a more uniform clamping force on the release paper on the adsorption plate 222a. Additionally, each pressure block contains an elastic pressure head. During the clamping process, the elastic pressure head dynamically balances the pressure, reducing fluctuations in clamping force caused by equipment vibration or operational errors, ensuring the stability and consistency of the clamping force. Furthermore, the adaptive adjustment of the elastic pressure head reduces rigid contact between the pressure block and the release paper.

[0049] In the preferred embodiment of this utility model, the peeling assembly 223 includes a peeling plate 223a, a pre-peeling platform 223b, and a peeling drive component 223c; the peeling drive component 223c supports and drives the peeling plate 223a to move between the pre-peeling platform 223b and the pressing assembly 222 in a direction parallel to the unwinding direction, ensuring the continuity of the peeling process, reducing the possibility of production interruption, and further improving the continuity and stability of production.

[0050] In this invention, the attaching device further includes a vision positioning component, which comprises a first camera 5 mounted on the conveyor belt 1 and a second camera 6 mounted on the transport path of the transport component 3. The first camera 5, mounted on the conveyor belt 1, can monitor the position and orientation of the unloaded fabric assembly in real time during the conveying process, while the second camera 6, mounted on the transport path of the transport component 3, can monitor the position and orientation of the loaded fabric in real time during the transport process. The automated control of the vision positioning component reduces the need for manual intervention. Operators do not need to frequently adjust the position of the loaded fabric or the path of the transport component 3, thereby improving production efficiency.

[0051] In a preferred embodiment of this invention, the conveying assembly 3 further includes an R-axis assembly 33; the R-axis assembly 33 is disposed in the linear conveying assembly 32 and is used to drive the adsorption head 31 to rotate along a vertical line. In actual production, the feed cloth may need to be attached at a specific angle due to irregular shape or special requirements of the attachment position. The rotation function of the R-axis assembly 33 ensures that the adsorption head 31 adsorbs and places the feed cloth at the optimal angle, thereby improving the accuracy of attachment.

[0052] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
