Description

Technical Field

[0001] This utility model belongs to the field of mask fabric processing, and in particular relates to a mask fabric conveying device. Background Technology

[0002] In today's highly developed textile and mask fabric processing industry, mask fabric conveying devices undoubtedly play a crucial and fundamental role in the conveying of mask fabrics.

[0003] Some conveying devices struggle to adjust the conveying pressure flexibly based on the thickness and material characteristics of the mask fabric. Different types of mask fabrics have vastly different requirements for conveying pressure. Excessive pressure may cause the mask fabric to deform or be damaged; insufficient pressure may cause the mask fabric to slip or shift during conveying, affecting processing accuracy and efficiency. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a mask fabric conveying device, which aims to solve the problem that existing mask fabric conveying devices are unable to flexibly adjust the conveying pressure according to the thickness, material and other characteristics of the mask fabric.

[0005] The present invention adopts the following technical solution:

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-4As shown, the mask fabric conveying device includes a frame 1 with a pair of left and right sliding openings 2. A pair of upper and lower sliding seats 3 are provided in the sliding openings 2. A pressure roller 4 and an intermediate roller 5 are respectively rotatably provided between the upper and lower sliding seats 3. A compression spring 6 is provided between the upper and lower sliding seats 3 on the same side. A drive wheel 7 is rotatably provided in the frame 1 below the intermediate roller 5. A transmission gear 9 is provided on the drive wheel 7, the intermediate roller 5, and the pressure roller 4. The transmission gears 9 mesh with each other. A drive motor 10 is also provided on the frame 1 to drive the drive wheel 7 to rotate. An adjustment component is provided on the top of the frame 1 directly opposite the pressure roller 4.

[0022] In today's highly developed textile and mask fabric processing industry, mask fabric conveying devices undoubtedly play a crucial and fundamental role in the conveying of mask fabrics.

[0023] In practice, the mask fabric passes between the pressure roller and the intermediate roller, and the pressure roller maintains a state of pressure on the mask fabric under the action of the adjustment component. When using this device to transport mask fabric, firstly, based on the thickness of the mask fabric, the distance between the pressure roller and the intermediate roller is adjusted by the adjustment component to ensure that the mask fabric can pass smoothly through this distance. Then, the adjustment component is used again to press the pressure roller firmly against the mask fabric. At this time, the transmission gears on the drive wheel, intermediate roller, and pressure roller mesh with each other. Then, the drive motor is started, and the drive motor drives the drive wheel to rotate, and the intermediate roller and pressure roller rotate synchronously. As the mask fabric passes between the pressure roller and the intermediate roller, it is transported forward under their clamping and rotational action. During this process, the compression spring also adaptively adjusts the distance between the pressure roller and the intermediate roller according to the thickness of the mask fabric to ensure a stable clamping force on the mask fabric.

[0024] As a specific structure, such as Figure 4 The adjustment assembly includes a pair of upper and lower fixing plates, with the upper fixing plate marked as 111 and the lower fixing plate marked as 112. The upper fixing plate 111 is fixedly installed, and the two ends of the lower fixing plate 112 are slidably installed in the sliding opening 2 on the same side. The bottom surface of the lower fixing plate 112 is provided with a pair of adjusting seats 12, and a pair of rollers 13 are rotatably mounted on the adjusting seats 12. The upper fixing plate 111 is provided with a pair of adjusting screw sleeves 14, and an adjusting rod 15 is screwed into the adjusting screw sleeves 14. The bottom of the adjusting rod 15 is rotatably connected to the lower fixing plate 112.

[0025] In the above process, after the mask fabric passes through the gap between the pressure roller and the intermediate roller, the gap between the pressure roller and the intermediate roller is adjusted by the adjusting component, so that the pressure roller presses the mask fabric tightly. Specifically: First, the worker rotates the adjusting rod, causing it to move downwards within the adjusting screw sleeve, thereby causing the lower fixed plate to move down a small distance. The two pairs of rollers on the left and right move downwards and press down on the pressure roller, causing it to move downwards a small distance, thus pressing the pressure roller tightly against the mask fabric. During the downward movement of the pressure roller, the compression spring is further compressed.

[0026] Similarly, in practice, the distance between the pressure roller and the middle roller can be adjusted according to the thickness and material of the mask fabric to improve the adaptability of this device.

[0027] As a preferred structure, such as Figure 3 The shaft of the pressure roller 4 has both ends located within the upper slide block 3 on the same side, and a pusher seat 16 is slidably provided within both upper slide blocks 3. The inner side of the pusher seat 16 forms a conical pusher portion. An adjusting spring 17 is provided at the tail of the pusher seat 16 within the upper left slide block 3, and an adjusting screw 18 is screwed inwards onto the upper right slide block 3. The end of the adjusting screw 18 abuts against the pusher seat 16 on the same side. Conical holes 19 are respectively opened at both ends of the shaft of the pressure roller 4 corresponding to the pusher portion.

[0028] In this structure, the shaft is located between the left and right push seats. The pushing parts of the two push seats are located inside the conical holes. By rotating the adjusting screw, the adjusting screw pushes the corresponding push seat to slide slightly within the upper right slide, and the pushing part engages with the conical hole, thereby fine-tuning the position of the pressure roller.

[0029] In addition, such as Figure 1 The support frame 1 has a row of arc-shaped grooves 20 on both the front and rear sides. The arc-shaped grooves 20 have threaded holes 21. The mask fabric conveying device also includes a guide assembly. The guide assembly includes a guide rod 22. A guide wheel 23 is rotatably mounted on the guide rod 22. The two ends of the guide rod 22 match the arc-shaped grooves 20. Both ends of the guide rod are fitted with locking screws (not shown in the figure). The locking screws pass through the guide rod and are screwed into the threaded holes.

[0030] In the diagram, both ends of the guide rod have cross-sections, and these ends match the arc-shaped grooves. Before conveying the mask fabric, the specific installation position of the guide rod can be adjusted according to the width of the mask fabric and the conveying path, so that the guide wheel guides the mask fabric and prevents the mask fabric from deviating. After determining the installation position of the guide wheel, first place the guide rod inside it into the corresponding pair of arc-shaped grooves, and then tighten the locking screws to fix the guide rod.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
