Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film deviation-correcting equipment, in particular to a centering mechanism. Background Art
[0002] Hot glue coating machines replace traditional painting processes and are generally suitable for applying decorative strips, PVC film, and melamine paper to surfaces such as furniture wood panels and decorative paint paper. With the continuous improvement of people's living standards, the requirements for coating surfaces such as furniture wood panels and decorative paint paper are becoming increasingly higher. Furniture wood panels require both a decorative film with a textured texture and a protective layer of transparent PVC film. Existing coating machines can easily cause the film to shift during transport, causing the center of the film to be misaligned with the center of the wood panel during application, resulting in poor quality and low efficiency. Utility Model Content
[0003] In order to solve the technical defects mentioned in the above background technology, the purpose of the present utility model is to provide a centering mechanism.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The cam is secured to a location where the roll of film is moved along the guide rails and the guide rails are secured to a location where the roll of film is moved along the guide rails.
[0006] By adopting this technical solution, the correction drive unit drives the correction roller in reciprocating motion. The friction of the correction roller causes the film in close contact to swing left and right. The continuous reciprocating motion of the correction roller uses a photoelectric sensor to identify the film's position, accurately positioning the film along the two edges of the sheet material, ensuring precise application. The first and second guide rods are both tilted relative to the central axis of the sheet material, reducing the adjustment stroke and improving both efficiency and precision, resulting in higher-quality and more efficient film application.
[0007] Furthermore, the first guide rod and the second guide rod are both provided with a correction seat. The correction seat includes a fixing portion, a connecting portion and a correction portion. The fixing portion is sleeved on the circumference of the corresponding first guide rod or the second guide rod, the lower end of the connecting portion is connected to the upper end of the fixing portion, and the lower end of the correction portion is connected to the upper end bearing of the connecting portion so that the correction portion and the connecting portion rotate along the central axis. The correction portion is provided with a mounting groove, and the end of the correction roller is inserted into the mounting groove, so that the correction roller can quickly change direction during the reciprocating motion, thereby improving the efficiency and accuracy of the correction.
[0008] Furthermore, the fixing portion is configured as a square structure, the connecting portion and the correcting portion are both configured as cylindrical structures, and the diameter of the connecting portion is larger than the diameter of the correcting portion, resulting in a compact structure and easy installation.
[0009] Furthermore, the deflection correction drive unit includes a deflection correction motor, a lead screw, and a slide. The deflection correction motor is mounted on the first fixed seat, and one end of the lead screw is fixedly connected to the output shaft of the deflection correction motor. The slide is mounted on the lead screw and fixedly connected to the corresponding deflection correction seat. The deflection correction motor uses the lead screw to convert circular motion into linear motion to drive the deflection correction roller to reciprocate, thereby improving operational stability and efficiency.
[0010] Furthermore, the screw rod is arranged in parallel with the first guide rod, which saves energy loss and improves operational stability.
[0011] Furthermore, the correction drive unit further includes an induction plate, a first travel switch, and a second travel switch. The induction plate is protrudingly disposed on a side of the slide facing away from the correction seat. The first and second travel switches are spaced apart on the first fixed seat along the direction of movement of the slide. The first and second travel switches are used to limit the reciprocating travel of the slide, thereby improving the safety performance of the equipment.
[0012] Furthermore, the first fixing base includes a first fixing plate and two first supports. The first fixing plate and the first guide rod are tilted at the same angle, resulting in a compact structure and reduced space usage. Two first supports are spaced apart on one side of the first fixing plate. The first supports are provided with first fixing holes, and the ends of the first guide rod are respectively fixed in the corresponding first fixing holes, making installation and removal very convenient.
[0013] Furthermore, the second fixing base includes a second fixing plate and two second supports. The second fixing plate and the second guide rod are arranged at an angled angle, resulting in a compact structure and reduced space usage. The second fixing plate is provided with two second supports spaced apart from each other, each of which is provided with a second fixing hole. The ends of the second guide rod are respectively fixed in the corresponding second fixing holes, facilitating easy installation and removal.
[0014] In summary, the beneficial effects of the present invention are:
[0015] This utility model uses a correction drive unit to drive the correction roller to reciprocate. The friction of the correction roller causes the adhesive film in close contact to swing left and right. The continuous reciprocating motion of the correction roller uses a photoelectric sensor to identify the position of the adhesive film, thereby accurately positioning the film along the two edges of the sheet material, ensuring precise adhesion to the sheet material. Both the first and second guide rods are tilted relative to the central axis of the sheet material, reducing the adjustment stroke and improving the efficiency and accuracy of the adjustment, resulting in higher-quality and more efficient adhesive film application.

[0024] The following is combined with Figure 1-3 , the embodiments of the utility model are further described in detail.
[0025] A centering mechanism 1, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it is located on one side of the air-expansion shaft 2, where the film roll is placed, and above the film pressing mechanism 3. It includes a first fixed seat 11 on one side of the film, a second fixed seat 12 on the other side of the film, a deflection correction drive unit 13 on the first fixed seat 11, a deflection correction roller 14, and a photoelectric sensor 15 for real-time monitoring of the film's position. A first guide rod 111 is mounted on the first fixed seat 11, and a second guide rod 121 is mounted on the second fixed seat 12. Both the first and second guide rods 111, 121 are tilted relative to the central axis of the sheet material. The ends of the first and second guide rods 111, 121, facing away from the air-expansion shaft 2, are closest to the central axis of the sheet material. One end of the deflection correction roller 14 is connected to the first guide rod 111, and the other end is connected to the second guide rod 121. The side of the film is in close contact with the circumference of the deflection correction roller 14. The deflection correction drive unit 13 is connected to one end of the deflection correction roller 14 to drive the deflection correction roller 14 in reciprocating motion to center the film.
[0026] The deflection correction drive unit 13 drives the deflection correction roller 14 in reciprocating motion. The friction of the deflection correction roller 14 causes the film in close contact to swing left and right. The continuous reciprocating motion of the deflection correction roller 14 allows the photoelectric sensor 15 to identify the film's position, accurately positioning the film along the sheet's edges or central axis, ensuring precise attachment of the film to the sheet. The first and second guide rods 111, 121 are both tilted relative to the sheet's central axis, reducing the required adjustment range and improving both efficiency and precision, resulting in higher-quality and more efficient film attachment.
[0027] In this embodiment, please refer to Figure 2 、 Figure 3 The first fixing base 11 includes a first fixing plate 112 and two first supports 113. The first fixing plate 112 and the first guide rod 111 are tilted at the same angle, resulting in a compact structure and reduced space. Two first supports 113 are spaced apart on one side of the first fixing plate 112. The first supports 113 are provided with first fixing holes. The ends of the first guide rod 111 are respectively fixed in the corresponding first fixing holes, making installation and removal very convenient.
[0028] The second fixing base 12 includes a second fixing plate 122 and two second supports 123. The second fixing plate 122 and the second guide rod 121 are tilted at the same angle, resulting in a compact structure and reduced space usage. The second fixing plate 122 is spaced apart from the second supports 123, each with a second fixing hole. The ends of the second guide rod 121 are secured to their corresponding second fixing holes, making installation and removal easy.
[0029] The width of the first fixing plate 112 is greater than that of the second fixing plate 122, providing space for mounting the deflection correction drive unit 13. The identical structure of the first support 113 and the second support 123 facilitates synchronization of the heights of the first guide rod 111 and the second guide rod 121, maintaining them at the same height. Furthermore, the identical structure and dimensions of the first guide rod 111 and the second guide rod 121 save costs and facilitate control of the reciprocating motion of the deflection correction roller 14.
[0030] In this embodiment, please refer to Figure 3, the first guide rod 111 and the second guide rod 121 are both provided with a correction seat 16. The correction seat 16 includes a fixing portion 161, a connecting portion 162 and a correction portion 163. The fixing portion 161 is mounted on the circumferential side of the corresponding first guide rod 111 or the second guide rod 121, the lower end of the connecting portion 162 is connected to the upper end of the fixing portion 161, and the lower end of the correction portion 163 is connected to the upper end bearing of the connecting portion 162 so that the correction portion 163 and the connecting portion 162 can rotate along the central axis to improve the flexibility of the correction roller 14 in changing direction. A mounting groove is provided on the correction portion 163, and the end of the correction roller 14 is inserted into the mounting groove, so that the correction roller 14 can quickly change direction during the reciprocating motion, thereby improving the efficiency and accuracy of the correction.
[0031] The fixing portion 161 is configured as a square structure, the connecting portion 162 and the correcting portion 163 are both configured as cylindrical structures, and the diameter of the connecting portion 162 is larger than the diameter of the correcting portion 163 , resulting in a compact structure and easy installation.
[0032] In this embodiment, please refer to Figure 2 、 Figure 3 The deflection correction drive unit 13 includes a deflection correction motor 131, a screw 132, and a slide 133. The deflection correction motor 131 is mounted on the first fixed base 11, with one end of the screw 132 fixedly connected to the output shaft of the deflection correction motor 131. The slide 133 is mounted on the screw 132 and fixedly connected to the corresponding deflection correction base 16. The deflection correction motor 131 uses the screw 132 to convert circular motion into linear motion to drive the deflection correction roller 14 to reciprocate, improving operational stability and efficiency.
[0033] The screw rod 132 is arranged in parallel with the first guide rod 111, which saves energy loss and improves the stability of operation. The screw rod 132 is arranged on the first fixed plate 112 through two bearing seats 137.
[0034] The deflection correction drive unit 13 further includes a sensing plate 134, a first travel switch 135, and a second travel switch 136. The sensing plate 134 protrudes from the side of the slide 133 facing away from the deflection correction base 16. The first travel switch 135 and the second travel switch 136 are spaced apart on the first fixed base 11 along the direction of movement of the slide 133. The first travel switch 135 and the second travel switch 136 are used to limit the reciprocating travel of the slide 133, thereby improving the safety performance of the device.
[0035] During the film pasting process, the correction motor 131 switches to forward or reverse rotation based on the position of the film sensed by the photoelectric sensor switch 15, thereby driving the screw rod 132 to rotate forward or reverse. The screw rod 132 converts the circumferential movement into linear motion through the slide 133, thereby driving the correction seat 16 connected to the slide 133 and the correction roller 14 and another correction seat 16 thereon to reciprocate together, thereby realizing rapid adjustment of the position of the film, improving the accuracy and efficiency of the glue pasting, and improving the yield of the product.
[0036] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
