Description

Technical Field

[0001] This utility model relates to the field of overfeeding device technology, and in particular to an overfeeding device for a brush. Background Technology

[0002] In the textile and related fabric processing industry, the brush overfeed device is mainly responsible for conveying the fabric to the subsequent processing stage in a stable and precise manner. Its performance directly affects the quality of the final product and production efficiency.

[0003] Currently, traditional brush overfeed devices rely solely on adjusting the angle of rubber wheels to change the fabric's compression. This single adjustment method has significant limitations. When the fabric's conveying angle needs to be changed, existing devices struggle to achieve precise adjustment. For example, in certain specialized dyeing processes, the fabric must enter the dyeing equipment at a specific angle to ensure uniform dye adhesion. Existing designs also suffer from the same shortcomings in adjusting the fabric output height. Different types of fabric, due to differences in thickness, material, and subsequent processing steps, have varying requirements for output height.

[0004] Therefore, the shortcomings of traditional devices in terms of fabric conveying angle, output height adjustment, and the adaptability of the fabric support mechanism have become bottlenecks restricting the improvement of production efficiency and the optimization of product quality. Therefore, it is necessary to develop a new type of brush overfeed device that can effectively adjust the fabric conveying angle and output height. Utility Model Content

[0005] This utility model provides a brush overfeeding device to solve the problems in the prior art.

[0006] The present invention adopts the following technical solution: a brush overfeeding device, comprising: a base, a carrier plate hinged above the base; a rubber wheel rotatably connected to the carrier plate, a brush wheel with a diameter adapted to the rubber wheel being coaxially arranged on one side of the rubber wheel; a rotary drive mechanism disposed on the carrier plate to drive the rubber wheel and the brush wheel to rotate synchronously; an angle adjustment mechanism disposed on the base and the carrier plate to drive the carrier plate to flip; and a cloth support mechanism having two height-adjustable rollers, and a cloth support belt being driven between the two rollers, the cloth support belt being located below the rubber wheel and the brush wheel.

[0007] Preferably, the cloth support mechanism further includes two sets of lifting mechanisms, each set of lifting mechanisms having a bracket installed at its actuating end, and two rollers rotatably connected to the two brackets respectively.

[0008] Preferably, the lifting mechanism includes: a frame; a lifting plate disposed above the frame, the bracket being mounted on the lifting plate, and a bearing seat mounted on the lower end of the lifting plate; two guide rods, both of which are slidably connected to the frame along the longitudinal direction, and both guide rods are fixedly connected to the lifting plate; and a lead screw threaded into a threaded hole on the frame, the lead screw being arranged longitudinally, and its top end being mounted on the bearing seat; the lifting plate is moved up and down by rotating the lead screw.

[0009] Preferably, a knob is installed at the lower end of the lead screw.

[0010] Preferably, the carrier plate has two coaxially distributed rotating holes, and a rotating shaft is rotatably connected in the two rotating holes. The rubber wheel and the brush wheel are both coaxially fixedly mounted on the rotating shaft.

Driven by the rollers, the support belt rotates cyclically, smoothly lifting and conveying the fabric forward. This, combined with the driving action of the rubber and brush wheels, ensures the stability and accuracy of the fabric throughout the conveying process. If the fabric sags or deviates during conveying, its position can be corrected by readjusting the height of the rollers in the support mechanism, ensuring the fabric remains on the correct conveying path.

Detailed Implementation

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 6 As shown, this utility model embodiment provides a brush overfeeding device, which mainly includes a base 1, a rubber wheel 3, a rotary drive mechanism 5, an angle adjustment mechanism 6 and a cloth support mechanism 7, with a carrier plate 2 hinged above the base 1.

[0027] The rubber wheel 3 is rotatably connected to the carrier plate 2. A brush wheel 4 with a diameter adapted to the rubber wheel 3 is coaxially arranged on one side of the rubber wheel 3. Specifically, the carrier plate 2 has two coaxially distributed rotating holes 21. A rotating shaft 22 is rotatably connected in the two rotating holes 21. The rubber wheel 3 and the brush wheel 4 are both coaxially fixedly installed on the rotating shaft 22, thereby realizing the rotation function of the rubber wheel 3.

[0028] A rotary drive mechanism 5 is mounted on the carrier plate 2 to drive the rubber wheel 3 and brush wheel 4 to rotate synchronously; an angle adjustment mechanism 6 is mounted on the base 1 and the carrier plate 2 to drive the carrier plate 2 to rotate; the cloth support mechanism 7 has two height-adjustable rollers 71, and a cloth support belt 72 is driven between the two rollers 71, the cloth support belt 72 being located below the rubber wheel 3 and brush wheel 4. It should be noted that the cloth support belt should be relatively loose (e.g., ...). Figure 1 The conveying angle of the fabric to be conveyed can be adjusted to a certain extent by lifting and lowering the two rollers 71. For large conveying angle adjustments, the corresponding support belt can be replaced directly.

[0029] The rotary drive mechanism 5 is activated, which drives the rubber wheel 3 and the coaxial brush wheel 4 to rotate synchronously. The rubber wheel 3, relying on the high friction between itself and the fabric, converts the rotational motion into a forward driving force on the fabric, causing it to move forward. Simultaneously, as the brush wheel 4 rotates, its bristles contact the fabric surface, smoothing and flattening the fabric, assisting the rubber wheel 3 in propelling the fabric forward, ensuring the fabric's flatness during transport, and reducing wrinkles and curling.

[0030] When conveying fabrics of different thicknesses or materials, the angle of the carrier plate 2 can be adjusted via the angle adjustment mechanism 6. The angle adjustment mechanism 6 rotates the carrier plate 2 around its hinge point with the base 1 according to actual needs, thereby changing the relative angle between the rubber wheel 3 and brush wheel 4 and the fabric support mechanism 7. This allows the rubber wheel 3 and brush wheel 4 to act on the fabric at a more suitable angle, ensuring optimal driving and finishing effects during conveying. For example, for some stiff, non-bending fabrics, the angle of the carrier plate 2 can be adjusted appropriately to make the contact between the rubber wheel 3 and brush wheel 4 and the fabric closer, enhancing the driving force on the fabric; while for some soft, easily deformable fabrics, the angle can be adjusted to make the force exerted by the rubber wheel 3 and brush wheel 4 on the fabric gentler, avoiding damage to the fabric.

[0031] During fabric conveying, the fabric support mechanism 7 plays a crucial supporting role. Two height-adjustable rollers 71 adjust according to the fabric thickness and its output position (which may vary depending on different requirements) to ensure appropriate spacing and pressure between the fabric support belt 72 and the rubber wheels 3 and brush wheels 4. Driven by the rollers 71, the fabric support belt 72 rotates cyclically, smoothly lifting and conveying the fabric forward. This, combined with the driving action of the rubber wheels 3 and brush wheels 4, ensures the stability and accuracy of the fabric throughout the conveying process. If the fabric sags or deviates during conveying, its position can be corrected by readjusting the height of the rollers 71 in the fabric support mechanism 7, ensuring the fabric remains on the correct conveying path.

[0032] Therefore, in this embodiment, the angle adjustment mechanism 6 can flexibly adjust the relative angle between the rubber wheel 3 and the brush wheel 4 and the fabric support mechanism 7 according to the material and characteristics of different fabrics, so that the device can adapt to the processing needs of various fabrics. The design of the two height-adjustable rollers 71 and the fabric support belt 72 in the fabric support mechanism 7 can be precisely adjusted according to the thickness of the fabric, providing stable support for the fabric and preventing problems such as sagging and deviation of the fabric during the conveying process.

[0033] In some practical applications, refer to Figures 4 to 6 As shown, the cloth support mechanism 7 also includes two sets of lifting mechanisms. Each set of lifting mechanisms has a bracket 73 installed at its execution end, and two rollers 71 are rotatably connected to the two brackets 73 respectively.

[0034] Specifically, the lifting mechanism includes a frame 74; a lifting plate 75 is disposed above the frame 74, and a bracket 73 is installed on the lifting plate 75. A bearing seat 76 is installed at the lower end of the lifting plate 75; two guide rods 77 are configured, both of which are slidably connected to the frame 74 along the longitudinal direction, and both guide rods 77 are fixedly connected to the lifting plate 75; a lead screw 78 is threaded into a threaded hole on the frame 74, the lead screw 78 is arranged longitudinally, and its top end is installed on the bearing seat 76; the lifting plate 75 is moved up and down by rotating the lead screw 78. It should be noted that a knob 79 is installed at the lower end of the lead screw 78 to facilitate the operator to rotate the lead screw 78, and the height of the lead screw 78 can also be automatically adjusted by a motor drive.

[0035] In some practical applications, refer to Figures 1 to 3As shown, the rotary drive mechanism 5 includes a reduction gearbox 51, which is mounted on the upper end of the carrier plate 2; a rotary motor 52 whose output shaft is connected to the input end of the reduction gearbox 51; a drive wheel 53 coaxially mounted on the output end of the reduction gearbox 51; and a driven wheel 54 coaxially mounted on the rotating shaft 22 and connected to the drive wheel 53 via a transmission belt. By running the rotary motor 52 and undergoing initial speed adjustment through the reduction gearbox 51, the drive wheel 53 can be driven to rotate. Under the action of the transmission belt, the rotating shaft 22 is driven to rotate, thereby achieving the purpose of synchronous rotation of the rubber wheel 3 and the brush wheel 4 on the rotating shaft 22.

[0036] In some practical applications, refer to Figures 1 to 3 As shown, the angle adjustment mechanism 6 includes: a hinge plate 61 hinged to the carrier plate 2; a linear drive source 62 mounted on the hinge plate 61, and the outer end of its output shaft is hinged to the base 1; the linear drive source 62 operates to drive the hinge plate 61 to rotate up and down.

[0037] The linear drive source 62 is the power core of the angle adjustment mechanism 6. Common linear drive sources 62 include cylinders, hydraulic cylinders, or electric actuators. When the linear drive source 62 receives a control signal and starts running, its output shaft will produce linear motion. Since the outer end of the output shaft of the linear drive source 62 is hinged to the base 1, and the linear drive source 62 itself is mounted on a hinge plate 61 hinged to the carrier plate 2, when the output shaft of the linear drive source 62 extends or retracts, it will push the hinge plate 61 to rotate around its hinge point with the carrier plate 2.

[0038] As the hinge plate 61 flips up and down, the carrier plate 2 will also adjust its angle around the hinge point with the base 1. As shown in the figure, when the output shaft of the linear drive source 62 extends, it will push the hinge plate 61 upward, thereby causing the carrier plate 2 to flip upward at a certain angle.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
