Description

Technical Field

[0001] The utility model relates to a relatively large range, in particular to a reverse coating device with adjustable coating amount. Background Art

[0002] There are many coating methods and equipment used in coating machines at home and abroad, but each coating equipment has shortcomings such as small width, low speed, and obvious insufficient coating effect, which makes it difficult to meet customers' large-scale and high-speed production needs. Therefore, the reverse coating device solves the above problems well.

[0003] However, although the existing reverse coating device can improve the coating quality to a certain extent, in order to meet different coating requirements, such as coating thickness, coating uniformity, etc., it is necessary to adaptively adjust the placement and wrap angle of the adjusting roller relative to the coating roller. The operation is inconvenient during the adjustment of the adjusting roller, and after the subsequent coating is completed, the coating roller and the material are prone to be difficult to separate, resulting in material waste at the rear end of the coating.

DETAILED DESCRIPTION

[0020] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0021] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0022] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0023] See also Figure 1-Figure 5 In an embodiment of the utility model, a reverse coating device with adjustable coating amount includes a frame 1, wherein the frame 1 includes two side plates, a receiving space is formed between the two side plates, and also includes a coating roller 7, an adjusting roller 6 and a driving member arranged in the receiving space, wherein: the coating roller 7 is detachably mounted on the frame 1 and can be driven to rotate by a driving source mounted on the frame 1, two adjusting rollers 6 are provided, both ends of the two adjusting rollers 6 are connected to a movable frame 3, the movable frame 3 is rotatably connected to the frame 1 through a connecting shaft 15, and the movement direction of the material bypassing the two adjusting rollers 6 is opposite to the rotation direction of the coating roller 7; a driving member connected to the movable frame 3 is also installed on the frame 1, and the driving member is used to drive the movable frame 3 to rotate so as to change the distance between the material and the coating roller 7.

[0024] In this embodiment, by setting the rotation direction of the coating roller 7 opposite to the movement direction of the material, the coating can be effectively reversed to the upper film, thereby improving the uniformity of the coating. At the same time, the placement angle of the movable frame 3 can be adjusted by the set driving member, thereby changing the position of the two adjusting rollers 6 relative to the coating roller 7, and then changing the distance between the material and the coating roller 7, so as to adjust the pressure between the material and the coating roller 7 to control the coating amount. Secondly, the material and the coating roller 7 are kept separated quickly during shutdown to eliminate the problem of uneven coating at the current material position caused by friction when the material is removed or the coating roller 7 is replaced.

[0025] Among them, it should be noted that the above-mentioned driving parts include but are not limited to the second cylinder 14, the hydraulic cylinder or the electric telescopic rod, the second cylinder 14, the hydraulic cylinder or the electric telescopic rod is rotatably connected to the frame 1, and the movable end of the second cylinder 14, the hydraulic cylinder or the electric telescopic rod is hinged to the movable frame 3, the connection position of the adjusting roller 6 and the movable frame 3 and the connection position of the second cylinder 14, the hydraulic cylinder or the electric telescopic rod and the movable frame 3 are respectively located on both sides of the connecting shaft 15, thereby forming a lever structure, which can drive the movable frame 3 to rotate when the second cylinder 14, the hydraulic cylinder or the electric telescopic rod telescopes, thereby changing the position of the adjusting roller 6.

[0026] For further information, see Figure 1 , Figure 2 and Figure 5 The driving source includes two symmetrically arranged connecting seats 11 rotatably mounted on the frame 1, and a notch 13 is formed on one side of the connecting seat 11 for the coating roller 7 to be radially inserted into the rotating shaft; a clamping shaft 10 is arranged in each of the two connecting seats 11, one of the clamping shafts 10 is rotatably connected to the connecting seat 11 and is fixed to the output shaft of the motor 2 mounted on the frame 1, and the other clamping shaft 10 is movably connected to the connecting seat 11 and is rotatably connected to the adjusting unit mounted on the frame 1.

[0027] When the coating roller 7 needs to be replaced, the clamping shaft 10 away from the motor 2 is pulled in the direction away from the motor 2 through the adjusting unit, so that the two clamping shafts 10 lose the clamping state on the rotating shaft of the coating roller 7. Then, the rotating shaft of the coating roller 7 can be pulled out from the notch 13 for replacement with the help of auxiliary machinery or manually. The operation is convenient. After the rotating shafts at both ends of the coating roller 7 to be replaced are put into the notch 13, it is only necessary to control the adjusting unit to connect the clamping shaft 10 with the coating roller 7, which effectively eliminates the problem of inconvenience in disassembly and assembly caused by directly fixing the coating roller 7 with bolts.

[0028] Exemplarily, in one implementation mode, the adjusting unit includes a first cylinder 8 mounted on the frame 1, a connecting plate 9 is fixed to the movable end of the first cylinder 8, and the connecting plate 9 is rotatably connected to the clamping shaft 10. The first cylinder 8 described here can also be replaced by an electric telescopic rod or a hydraulic cylinder, as long as the telescopic requirements are met, and this embodiment does not make any specific limitation on this.

[0029] A guide frame 12 is also fixed to the side of the connecting seat 11 facing the notch 13. The guide frame 12 is arranged in a horizontal direction so that when the coating roller 7 is disassembled, the guide frame 12 plays a certain supporting role on the coating roller 7, making it convenient to push the coating roller 7 for disassembly.

[0030] See also Figure 2-Figure 4 A feed roller 4 and a discharge roller 5 are rotatably mounted on the movable frame 3 . The material entering the frame 1 from the feed roller 4 passes through two adjusting rollers 6 and moves out of the frame 1 around the discharge roller 5 .

[0031] Both ends of the adjusting roller 6 are rotatably mounted with a first slide 19 slidably connected to the movable frame 3, and the first slide 19 is connected to an adjusting mechanism installed on the movable frame 3. Exemplarily, in one embodiment, the adjusting mechanism includes a fixed seat 17 fixed on the movable frame 3 and a screw rod 18 rotatably connected to the fixed seat 17, one end of the screw rod 18 is fixed with a handwheel 16, and the other end is threadedly connected to the first slide 19.

[0032] When the positions of the two adjusting rollers 6 need to be changed, the hand wheel 16 is manually turned to drive the screw 18 to rotate. When the screw 18 rotates, the placement position of the first slide 19 is changed, thereby realizing the vertical position change of the adjusting roller 6. It should be noted that since the position adjustment of the two adjusting rollers 6 can be controlled separately, the distance between the material and the coating roller 7 can be changed by adjusting the relative position of the two adjusting rollers 6, and the contact position between the material and the coating roller 7 can also be changed according to needs, thereby meeting different needs and having a wide range of applications.

[0033] A slider 21 is fixed to the first slide 19, and the slider 21 slides with the guide rail 20 arranged on the frame 1, so as to realize the directional movement and guidance of the first slide 19 relative to the frame 1, and ensure that the first slide 19 will not rotate with the screw rod 18 when the screw rod 18 rotates.

[0034] Furthermore, both ends of the feed roller 4 and the discharge roller 5 are rotatably mounted with a second slide 23 movably connected to the frame 1 , and the second slide 23 is connected to an adjustment member 22 mounted on the frame 1 for adjusting the position of the feed roller 4 or the discharge roller 5 .

[0035] The adjustment member 22 described above can adjust the placement position of the second slide 23, so that during the coating process, the tension of the material can be adjusted to a certain extent according to the tension requirement of the material to ensure the coating effect. The adjustment method of the second slide 23 by the adjustment member 22 is the same as the adjustment method of the first slide 19, so this embodiment will not be repeated.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
