Description

Technical Field

[0001] This application relates to the field of coating machine technology, specifically to a feeding device for a coating machine. Background Technology

[0002] Coating is an important process in fabric finishing. With the increasing demands on fabrics in the market, there is often a need to set different types of coatings on the front and back of the fabric. The feeding device also needs to be adjusted according to the coating machine. Currently, the feeding devices of fabric coating machines are generally limited in structure and position or fixed, and cannot adjust the angle and position, making it impossible to feed different models of coating machines. Therefore, this application proposes a feeding device for coating machines. Utility Model Content

[0003] The purpose of this application is to provide a feeding device for a coating machine in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] The feeding device for the coating machine includes:

[0006] A support frame with two horizontal plates on it, through which a feeding roller rotates, and one end of the feeding roller is connected to a motor mounted on one of the horizontal plates;

[0007] An adjusting frame is hinged to a support. A missing gear is fixed on the adjusting frame at the hinge point. An adjusting screw is threaded through the support. A lifting plate is rotatably connected to the end of the adjusting screw. A rack that meshes with the teeth of the missing gear is provided on the lifting plate. A guide roller is rotatably mounted on the adjusting frame. A linkage rod is rotatably mounted on the support. A pulley assembly is connected between the linkage rod and the guide roller and the feeding roller, respectively.

[0008] Furthermore, the adjusting frame is provided with a mounting frame, and a pressure roller is rotatably mounted on the mounting frame. Both the pressure roller and the guide roller are fixed with spherical gears, and the teeth of the two spherical gears mesh.

[0009] Furthermore, both the guide roller and the pressure roller are constructed with two spiral protrusions, and the two spiral protrusions rotate in opposite directions.

[0010] Furthermore, the mounting frame is rotatably mounted on the adjusting frame and its rotation point is coaxial with the guide roller. The adjusting frame is provided with a fixing component for fixing the mounting frame.

[0011] Furthermore, the fixing component includes a support plate mounted on the mounting frame, the adjusting frame having a plurality of annularly distributed insertion holes, an insertion rod slidably mounted on the support plate to engage with the insertion holes, a limiting plate fixed on the insertion rod, and a spring sleeved on the insertion rod between the limiting plate and the support plate.

[0012] Furthermore, a connecting plate is installed on another horizontal plate through the cooperation of a screw and a screw hole. A through hole is opened through the connecting plate, and the end of the feeding roller away from the motor is inserted into the through hole.

[0013] Furthermore, the feeding roller has an internal hollow structure, and several through slots are opened on the outer surface of the feeding roller. A bidirectional lead screw is coaxially rotatably inserted inside the feeding roller. Both ends of the bidirectional lead screw are threaded with movable plates.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1-6 As shown, a coating machine feeding device according to one embodiment of this application includes:

[0025] The bracket 1 is set next to the coating machine or on other mounting components of the coating machine. Two horizontal plates 2 are set on it. A feeding roller 3 rotates through the two horizontal plates 2. The feeding roller 3 is used to place the roll of fabric to be coated. One end of the feeding roller 3 is connected to a motor 4 set on one of the horizontal plates 2. The motor 4 does work and its output shaft drives the feeding roller 3 to rotate, thereby performing the unwinding and feeding operation.

[0026] An adjusting frame 5 is hinged to a support 1. Preferably, the inner wall of the support 1 has hinge shafts on opposite sides. The adjusting frame 5 has two cylindrical bodies, which are rotatably mounted on the two hinge shafts. A missing gear 6 is fixed to the adjusting frame 5 at the hinge point. The missing gear 6 is fixed to the cylindrical body. An adjusting screw 7 is threaded through the support 1. The end of the adjusting screw 7 is rotatably connected to a lifting plate 8. The lifting plate 8 is provided with a rack 9 that meshes with the teeth of the missing gear 6. A guide roller 10 is rotatably mounted on the adjusting frame 5. When the fabric is fed, the guide roller 10 is wound around it to guide the fabric. Twisting the adjusting screw 7 rotates the lifting plate 8, thereby driving the lifting plate 8 to rise and fall. At this time, the missing gear 6 and the rack 9 mesh, thereby driving the fabric to rise and fall. The movable adjustment frame 5 rotates around the hinge point to adjust the position of the guide roller 10, thereby adjusting the height and angle of the feeding. A linkage rod 11 is rotatably installed on the support 1. The linkage rod 11 is connected to the guide roller 10 and the feeding roller 3 by a pulley assembly 12. Preferably, the linkage rod 11 is coaxial with the hinge shaft. Under the linkage of the two pulley assemblies 12, when the motor 4 drives the feeding roller 3 to rotate, it can also drive the guide roller 10 to rotate synchronously. This not only gives the guide roller 10 active transmission stress to assist the fabric in feeding, but also ensures that even after the adjustment frame 5 is adjusted by rotating around the hinge point, the guide roller 10 still has transmission stress synchronously and in the same direction as the feeding roller 3.

[0027] In this scheme, the position of the feeding roller 3 is fixed, and the guide roller 10 guides and transmits the fabric. At the same time, the adjustment frame 5 can rotate and adjust around the hinge point to adjust the height and angle of the guiding transmission, which is suitable for different types of coating production needs. After adjustment, both the guide roller 10 and the feeding roller 3 share the driving force of the motor 4, so that the guide roller 10 has active transmission stress to assist the fabric in transmission and achieve the function of feeding.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, the adjusting frame 5 is provided with a mounting frame 13, and a pressure roller 14 is rotatably mounted on the mounting frame 13. Both the pressure roller 14 and the guide roller 10 are fixed with spur gears 15, and the teeth of the two spur gears 15 mesh. When the fabric is wrapped around the guide roller 10, the pressure roller 14 cooperates with the guide roller 10 to roll the fabric. Under the meshing of the teeth of the two spur gears 15, when the guide roller 10 rotates, the pressure roller 14 rotates synchronously in the opposite direction, and cooperates with the guide roller 10 to roll and transmit the fabric, making the fabric transmission and feeding more stable.

[0029] like Figure 1 and Figure 2As shown, in some embodiments, both the guide roller 10 and the pressure roller 14 are constructed with two spiral protrusions 16, and the two spiral protrusions 16 rotate in opposite directions. Preferably, the two spiral protrusions 16 on the guide roller 10 and the pressure roller 14 located at the same end rotate in opposite directions. By constructing two spiral protrusions 16 on both the guide roller 10 and the pressure roller 14 with the two spiral protrusions rotating in opposite directions, the guide roller 10 and the pressure roller 14 can also flatten the fabric to both sides in the width direction when rolling and transferring the fabric, which plays a role in preventing wrinkles and flattening the fabric, thereby improving practicality.

[0030] like Figure 6 As shown, in some embodiments, the mounting frame 13 is rotatably mounted on the adjusting frame 5 and its rotation point is coaxial with the guide roller 10. The adjusting frame 5 is provided with a fixing member 17 for fixing the mounting frame 13. By rotatably connecting the mounting frame 13 and making its rotation point coaxial with the guide roller 10, the pressure roller 14 can be adjusted (with the guide roller 10 as the center for position adjustment). This ensures that the guide roller 10 cooperates with the pressure roller 14 to roll the fabric, while also preventing the fabric from covering the guide roller 10 and the pressure roller 14 too much. At the same time, even after the pressure roller 14 is adjusted, the guide roller 10 and the pressure roller 14 can effectively rotate synchronously in opposite directions under the meshing transmission of the two spur gears 15.

[0031] like Figure 6 As shown, in some embodiments, the fixing member 17 includes a support plate 1701 disposed on the mounting frame 13, and the adjusting frame 5 has a plurality of annularly distributed insertion holes 1702. An insertion rod 1703 is slidably disposed on the support plate 1701 and engages with the insertion holes 1702. A limiting plate 1704 is fixedly disposed on the insertion rod 1703, and a spring 1705 sleeved on the insertion rod 1703 is installed between the limiting plate 1704 and the support plate 1701. Preferably, the adjusting frame 5 has a cylinder, the guide roller 10 rotates through the cylinder, the insertion holes 1702 are opened on the cylinder, and the mounting frame 13 is constructed with… The sleeve is rotated and fitted onto the cylinder. When the mounting bracket 13 is rotated, the insertion rod 1703 is first pulled away from the insertion hole 1702, and then the mounting bracket 13 is rotated and adjusted. After the mounting bracket 13 is rotated and adjusted, the insertion rod 1703 is then movably inserted into the corresponding insertion hole 1702, thereby fixing the mounting bracket 13. By setting a limiting plate 1704 and a spring 1705 on the insertion rod 1703, the elastic force of the spring 1705 is used to resist the movement. Even if the mounting bracket 13 is rotated and adjusted, the insertion rod 1703 will not be dislodged from the insertion hole 1702 due to the change in position, thereby improving the stability of the fixation.

[0032] like Figure 2As shown, in some embodiments, a connecting plate 18 is installed on another horizontal plate 2 through the cooperation of a screw and a screw hole. A through hole is provided on the connecting plate 18. The end of the feeding roller 3 away from the motor 4 is inserted into the through hole. The fabric roll is installed on the feeding roller 3, and then the connecting plate 18 is installed and fixed on the horizontal plate 2 through the cooperation of the screw and the screw hole. At this time, one end of the feeding roller 3 is movably inserted into the through hole (preferably, the end of the feeding roller 3 is provided with a bearing wheel, which is rotatably inserted into the through hole), so that both ends of the feeding roller 3 have support points to ensure the stability of feeding. After the fabric roll is finished, the connecting plate 18 is removed first, and then the roll is removed.

[0033] like Figure 4 As shown, in some embodiments, the feeding roller 3 has an internal hollow structure, and several through slots 19 are opened on the outer surface of the feeding roller 3. A bidirectional lead screw 20 is coaxially rotatably inserted inside the feeding roller 3. Both ends of the bidirectional lead screw 20 are threaded with movable plates 21. Several support plates 23 are hinged between the two movable plates 21 through connecting rods 22. The several support plates 23 are respectively movably inserted through several through slots 19. Preferably, two connecting rods 22 on the same support plate 23 are respectively hinged to two movable plates 21. When the roll of fabric is placed on the feeding roller 3, the bidirectional lead screw 20 is twisted to rotate. Under the action of the bidirectional thread, the two movable plates 21 are driven to move synchronously in opposite directions. When the two movable plates 21 move away from each other, the connecting rods 22 drive the support plates 23 to expand, thereby abutting against the inner wall of the roll. By using the friction of the abutment, the roll is fixed. The method of fixing or unfixing the fabric roll is relatively simple and convenient.

[0034] like Figure 3 As shown, in some embodiments, an arc-shaped plate 24 is provided on the support plate 23, and the outer surface of the arc-shaped plate 24 is arrayed with anti-slip protrusions. By providing an arc-shaped plate 24 on the support plate 23 and opening anti-slip protrusions on the arc-shaped plate 24, the contact area and contact friction with the drum are increased, thereby improving the stability of the drum fixation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
