Description

Technical Field

[0001] The utility model relates to the technical field of oven guide rollers, in particular to a position-adjustable guide roller assembly in an oven. Background Art

[0002] Composite film refers to a multilayer structure formed by combining various plastics with paper, metal, or other materials through lamination, extrusion coating, and co-extrusion processes. Composite film generally consists of a substrate, laminating adhesive, barrier material, heat-sealing material, and printed and protective coatings. It is primarily used for packaging and as a coating. Plastic packaging and plastic packaging products are increasingly occupying a larger market share, especially composite plastic flexible packaging, which has been widely used in the food, pharmaceutical, and chemical industries. With the increasing demand for thin films, film drying ovens have many shortcomings. The guide roller assembly in the oven is fixed and cannot be adjusted. This makes it impossible to adjust the tension and relaxation of the composite film after the guide roller is positioned, and fine-tune it during the drying process. Utility Model Content

[0017] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.

[0018] like Figure 1-Figure 2 The shown guide roller assembly has an adjustable position in the oven, comprising a plurality of bases 1, with two groups of brackets vertically mounted on each group of bases 1, a guide roller mounted between the tops of the two groups of brackets, and mounted in the inner cavity of the oven, the bracket comprising a telescopic rod 2, a crossbeam 3 being horizontally mounted on the top of the telescopic rod 2, a movable frame 5 being slidably connected to the crossbeam 3, a U-shaped positioning frame 6 being mounted on the movable frame 5, the two ends of the U-shaped positioning frame 6 being vertically upward, and the slots therebetween are used to position the support shafts at both ends of the guide roller.

[0019] The guide roller is positioned between the U-shaped positioning frames 6 of the two sets of brackets. By raising and lowering the telescopic rod 2 and moving the sliding block on the beam 3, the position of the U-shaped frame is adjusted in both the X-axis and Y-axis directions, thereby changing the position of the guide roller and adjusting the tightness of the film.

[0020] Preferably, a guide groove 301 is provided at the top of the beam 3, and the guide groove 301 runs through both ends of the beam 3. A key 501 is installed at the bottom of the movable frame 5, and the key 501 is engaged with the guide groove 301. The engagement of the key 501 on the movable block with the guide groove 301 can limit the movable frame 5.

[0021] Preferably, a rack 302 is installed at the bottom of the inner cavity of the guide groove 301, a gear 502 is installed on the key 501, and a motor is installed in the movable frame 5. The motor is used to drive the gear 502 to rotate, and the gear 502 is engaged with the rack 302. The motor drives the gear 502 to rotate. Through the engagement of the gear 502 with the rack 302, the position of the movable frame 5 on the beam 3 can be changed, thereby driving the position adjustment of the guide roller in the X-axis direction.

[0022] Preferably, the U-shaped frame is rotatably mounted on the mobile frame 5 , with the axis of the rotating shaft being perpendicular to the crossbeam 3 , and can be positioned when the U-shaped frame is in a vertical state.

[0023] When the U-shaped frame is in the vertical position, the support shafts at both ends of the guide roller are positioned between the card slots of the U-shaped frame, thereby preventing the U-shaped frame from rotating. When the U-shaped frame is rotated until the inclined surfaces of the guide slopes 601 contact the upper surface of the cross beam 3, the inner side walls of the U-shaped frame are connected with the upper surface of the cross beam 3, which is convenient for the upper and lower rollers of the guide rollers. When the upper rollers are needed, the support shafts at both ends of the guide rollers are respectively placed on the cross beams 3 of the two sets of brackets and rolled into the card slots of the U-shaped frame. After the U-shaped frame is vertically positioned, the guide rollers can be positioned. When the lower rollers are needed, the U-shaped frame is rotated to the position as shown in the figure. Figure 4 After the guide roller is in the position shown, the guide roller can be transferred from the U-shaped frame to the crossbeam 3 to facilitate the subsequent removal of the guide roller.

[0024] Preferably, a reinforcing bracket 4 is installed at the connection portion between the top end of the telescopic rod 2 and the crossbeam 3 to enhance the strength of the crossbeam 3 .

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
