Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a material feeding correction and guiding device for a film applicator. Background Technology

[0002] Film applicators are used to apply strip films to flat surfaces such as glass, plastic sheets, and metal sheets, and are widely used in industrial automated production.

[0003] The feeding and guiding mechanism of the existing film applicator consists of a cover plate, a pad plate, and a guide groove. The strip film enters through the feed inlet of the feeding mechanism composed of the cover plate and the pad plate, passes through the closed space inside the cavity between the feed inlet and the discharge outlet, and extends to the unclosed space outside the cavity at the rear end of the discharge outlet, and extends a certain length out of the feed inlet to facilitate the pressure roller pressing the strip film after feeding.

[0004] In existing technology, the film strip is supported by a pad in the feeding mechanism and enters the guide groove. The part of the film strip suspended in front of the pad reaches the pressure roller to achieve feeding and guidance. However, some soft film strips and spirally wound film strips are prone to bending and deformation, and their movement direction is prone to deflection. They cannot pass through the pad and guide groove to be delivered to the pressure roller, resulting in missing film strips and incomplete film application. This affects work efficiency and requires a pause for manual correction before normal operation can resume. Utility Model Content

[0005] Based on the above analysis, the present invention aims to provide a material discharge correction and guiding device for a film applicator, in order to solve the technical problem that the movement direction of the film strip is prone to deflection in the prior art.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] This utility model provides a material feeding and guiding device for a film applicator, used for correcting and guiding strip film, including a feeding assembly, which includes a cover plate and a pad plate;

[0008] The cover plate is connected to the pad plate, the pad plate is used to support the strip membrane, and the cover plate and the pad plate cooperate to form a fully enclosed cavity, through which the strip membrane passes.

[0009] Furthermore, it also includes a guide groove, which is configured as a trapezoidal structure, and the feeding assembly can enter the guide groove.

[0010] Furthermore, the bottom width of the guide groove is smaller than the top width, and the bottom width of the guide groove is the same as the width of the strip film.

[0011] Furthermore, the width of the guide groove sidewall gradually increases along the direction of movement perpendicular to the strip film, and when the feeding assembly enters the guide groove, the distance between the feeding assembly and the bottom of the guide groove is 2mm to 5mm.

[0012] Furthermore, the inlet width of the guide groove is greater than the outlet width, and the outlet width of the guide groove is the same as the width of the strip film.

[0013] Furthermore, the width of the guide groove sidewall gradually increases along the direction of movement parallel to the strip film, and when the feeding assembly enters the guide groove, the distance between the feeding assembly and the bottom of the guide groove is 1mm to 2mm.

[0014] Furthermore, it also includes a flat groove, which is connected to the guide groove, and the width of the flat groove is the same as the width of the strip film.

[0015] Furthermore, the feeding assembly also includes an inlet and an outlet, wherein the strip film enters the feeding assembly through the inlet and exits the feeding assembly through the outlet.

[0016] Furthermore, the discharge port is configured with a beveled surface.

[0017] Furthermore, the side of the discharge port is chamfered.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] (1) The film applicator discharge correction and guiding device of this utility model has a cover plate and a pad plate forming a fully enclosed cavity, through which the strip film passes. The position of the strip film is restricted by the side wall of the cavity, thereby improving the guiding and correction effect of the strip film.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0034] Example 1

[0035] A specific embodiment of this utility model discloses a material correction and guiding device for a film applicator, used for correcting and guiding the strip film 2, such as... Figures 1-2As shown, the feeding assembly 1 includes a cover plate 11 and a pad plate 12. The cover plate 11 is connected to the pad plate 12, and the pad plate 12 is used to support the strip film 2. The cross section of the cover plate 11 or the pad plate 12 perpendicular to the direction of movement of the strip film 2 is set as a "C" shaped structure, so that the cover plate 11 and the pad plate 12 cooperate to form a fully enclosed cavity, and the width of the cavity is not less than the width of the strip film 2.

[0036] A feed inlet 13 is provided at one end of the cavity, and a discharge outlet 14 is provided at the other end. The strip film 2 enters the cavity through the feed inlet 13 and exits the cavity through the discharge outlet 14. The side wall of the cavity restricts the position of the strip film 2 in the feeding assembly 1, thereby guiding and correcting the movement direction of the strip film 2.

[0037] For example, the cover plate 11 and the pad plate 12 are connected by bolts.

[0038] Preferably, the cross section of the pad 12 perpendicular to the direction of movement of the strip film 2 is set as a "C" shape, which can extend the service life of the film applicator's discharge correction guide device, prevent the side wall of the cavity from being deformed due to long-term stress, and prevent gaps from forming between the side wall of the cavity and the pad 12, which would damage the fully enclosed structure and affect the guiding and correction effect on the strip film 2.

[0039] The cover plate 11 is provided with a cylinder hole 111. The existing cylinder can enter the cylinder hole 111 to press the strip film 2, so that the strip film 2 is close to the pad plate 12, thereby causing the feeding assembly 1 to move with the strip film 2. The existing technology of the cylinder entering the cylinder hole 111 to move the feeding assembly 1 with the strip film 2 is prior art, and will not be described in detail here.

[0040] When the film applicator is used for feeding, the strip film 2 enters the cavity formed by the cover plate 11 and the pad plate 12 through the feed port 13 and passes through the discharge port 14. The existing cylinder enters the cylinder hole 111 to press the strip film 2. The movement of the strip film 2 drives the feeding assembly 1 to move to deliver the strip film 2 that has passed through the discharge port 14 to the pressing component 3. After the pressing component 3 presses the strip film 2, the existing cylinder is moved out of the cylinder hole 111 so that the feeding assembly 1 does not move with the pressing component 3, thus completing the feeding process of the strip film 2. The movement direction of the strip film 2 is limited and corrected by the fully enclosed cavity formed by the cover plate 11 and the pad plate 12.

[0041] The pressing component 3 is existing technology, such as a pressure roller or pressure bar. The pressing component 3 can move up and down to press the strip film 2, which will not be described in detail here.

[0042] Preferably, the discharge port 14 is configured with a beveled surface to prevent the discharge port 14 from interfering with the movement of the pressing part 3.

[0043] Example 2

[0044] A specific embodiment of this utility model discloses a material correction and guiding device for a film applicator, used for correcting and guiding the strip film 2, such as... Figures 3-4 As shown, the difference from Embodiment 1 is that it also includes a guide groove 4, which is used to further guide and correct the strip film 2, thereby improving the guiding and correcting effect of the strip film 2.

[0045] Furthermore, such as Figure 4 As shown, the guide groove 4 is a trapezoidal structure with a bottom width smaller than the top width. The bottom width of the guide groove 4 is the same as the width of the strip film 2, so as to guide and limit the strip film 2. The width of the side wall of the guide groove 4 gradually widens along the direction perpendicular to the movement of the strip film 2. The top width of the guide groove 4 is greater than the width of the discharge port 14, so as to allow the feeding assembly 1 to enter the guide groove 4.

[0046] For example, when the feeding component 1 enters the guide groove 4, the distance between the feeding component 1 and the bottom of the guide groove 4 is 2mm to 5mm, such as 2mm, 3mm, 4mm, or 5mm, to prevent the feeding component 1 from colliding with the guide groove 4.

[0047] Preferably, the side of the discharge port 14 is chamfered to prevent the feeding assembly 1 from colliding with the guide groove 4.

[0048] When the aforementioned correction and guiding device is used for feeding, the existing cylinder causes the feeding assembly 1 to move into the guide groove 4 along with the strip film 2, and feeds the strip film 2 to contact the pressing member 3, so that the pressing member 3 presses down on the strip film 2. Under the action of the pressing member 3, the strip film 2 adheres tightly to the bottom of the guide groove 4. The existing cylinder is removed, and the feeding assembly 1 is moved out of the guide groove 4. This prevents the feeding assembly 1 from being in the guide groove 4 and causing the length of the strip film 2 entering the guide groove 4 from the outlet 14 to be too short, which would affect the guiding and correction effect of the guide groove 4 on the strip film 2. The side wall of the guide groove 4 guides the movement direction of the strip film 2 to prevent the strip film 2 from deviating during movement.

[0049] By setting a guide groove 4 with a bottom width smaller than the top width, the feeding assembly 1 can enter the guide groove 4, thereby increasing the guiding and correction effect on the strip film 2.

[0050] Example 3

[0051] A specific embodiment of this utility model discloses a material discharge correction and guiding device for a film applicator, such as... Figures 5-6 As shown, the difference from Embodiment 2 is that the guide groove 4 is set as a trapezoidal structure with an inlet width greater than the outlet width.

[0052] Furthermore, the outlet width of the guide groove 4 is the same as the width of the strip film 2, the width of the side wall of the guide groove 4 gradually widens along the direction of movement parallel to the strip film 2, and the inlet width of the guide groove 4 is greater than the width of the outlet 14, so that the feeding assembly 1 can enter the guide groove 4.

[0053] For example, when the feeding component 1 enters the guide groove 4, the distance between the feeding component 1 and the bottom of the guide groove 4 is 1mm to 2mm, such as 1mm, 1.5mm, or 2mm, to prevent the feeding component 1 from colliding with the guide groove 4.

[0054] When the aforementioned correction and guiding device is used for feeding, the existing cylinder causes the feeding assembly 1 to move into the guide groove 4 along with the strip film 2, and feeds the strip film 2 to contact the pressing member 3. After the pressing member 3 presses down on the strip film 2, the existing cylinder is removed, causing the feeding assembly 1 to move out of the guide groove 4. This prevents the feeding assembly 1 from being in the guide groove 4, which would cause the length of the strip film 2 entering the guide groove 4 from the outlet 14 to be too short, thus affecting the guiding and correction effect of the guide groove 4 on the strip film 2.

[0055] Preferred, such as Figure 6 As shown, it also includes a flat groove 5, which is connected to the outlet of the guide groove 4. The width of the flat groove 5 is the same as the width of the strip 2. When the strip 2 enters the guide groove 4, the inner wall of the guide groove 4 guides and corrects the movement direction of the strip 2. When the strip 2 moves to the flat groove 5, the flat groove 5 further corrects and guides the movement direction of the strip 2, so that the strip 2 maintains the correct movement path after leaving the flat groove 5, thereby further improving the accuracy of the movement of the strip 2.

[0056] Any aspects not covered in this utility model are applicable to the prior art.

[0057] Compared with existing technologies, the film applicator's discharge correction and guiding device of this utility model has a cover plate 11 and a pad plate 12 forming a fully enclosed cavity through which the film strip 2 passes. The sidewall of the cavity restricts the position of the film strip 2, thereby improving the guiding and correction effect of the film strip 2. The trapezoidal guide groove 4 allows the feeding component 1 to enter the guide groove 4, thereby improving the guiding effect of the feeding component 1 on the film strip 2. The inner wall of the guide groove 4 can further guide and correct the film strip 2, improving the accuracy of the film strip 2's movement. The flat groove 5 can further correct and guide the film strip 2, ensuring the accuracy of the movement direction of the film strip 2 after leaving the flat groove 5, thereby improving the guiding and correction effect.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
