Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot melt adhesive coating machine technology, and specifically to an automatic cutting mechanism for a hot melt adhesive coating machine. Background Technology
[0002] When hot melt adhesive coating machines coat sleeving plates with wrapping material, the wrapping material needs to be cut after the coating process to separate the coated sleeving plates and allow them to proceed to the next process. Traditional cutting methods often have many problems, such as uneven cutting and rough cut edges. Moreover, some existing cutting mechanisms have their cutting direction parallel to or improperly configured with the conveying mechanism, which can easily lead to skewed cuts when cutting the wrapping material between sleeving plates, affecting the quality of the coated product. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an automatic cutting mechanism for a hot melt adhesive coating machine, so as to solve the problems mentioned in the background art.

A horizontally positioned electric guide rail is mounted on the support plate, with the sliding direction of a slider on the electric guide rail forming an angle with the conveying direction of the conveying mechanism. A mounting base is mounted on the slider of the electric guide rail, and a vertical telescopic cylinder is longitudinally mounted on the mounting base. The telescopic rod of the vertical telescopic cylinder is positioned downwards and connected to an inverted L-shaped mounting plate. A horizontally positioned cutting drive motor is mounted on the inverted L-shaped mounting plate, and a circular cutting blade is connected to the rotating shaft of the cutting drive motor. The output terminal of the PLC controller is connected to the controlled terminals of the conveying mechanism, the electric guide rail, the vertical telescopic cylinder, and the cutting drive motor, respectively.
[0006] Preferably, the cutting direction of the circular cutting blade is at an obtuse angle to the conveying direction of the conveying mechanism.
[0007] Preferably, the top of the inverted L-shaped mounting plate is provided with two guide rods that pass through the mounting base and are slidably assembled with the mounting base. The two guide rods are arranged parallel to the vertical telescopic cylinder and symmetrically arranged on both sides of the vertical telescopic cylinder.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0018] An automatic cutting mechanism for a hot melt adhesive coating machine, combined with Figures 1 to 3 As shown, it includes a support plate 61, which is adjustablely positioned above the conveying mechanism. A horizontally positioned electric guide rail 62 is provided on the support plate 61. The sliding direction of the slider on the electric guide rail 62 is set at an angle to the conveying direction of the conveying mechanism. By adjusting the installation position of the support plate 61, the angle between the sliding direction of the slider on the electric guide rail 62 and the conveying direction of the conveying mechanism can be adjusted.
[0019] The electric guide rail 62 has a mounting base 63 on its slider. A vertical telescopic cylinder 64 is longitudinally mounted on the mounting base 63. The telescopic rod of the vertical telescopic cylinder 64 is positioned downwards and connected to an inverted L-shaped mounting plate 65. A horizontally positioned cutting drive motor 66 is mounted on the inverted L-shaped mounting plate 65. The rotating shaft of the cutting drive motor 66 is connected to a circular cutting blade 67. The circular cutting blade 67 moves under the drive of the electric guide rail 62, and its cutting direction is at an obtuse angle to the conveying direction of the conveying mechanism. When the cutting drive motor 66 drives the circular cutting blade 67 to rotate, the circular cutting blade 67 can perform a cutting action. At the same time, the electric guide rail 62 drives the inverted L-shaped mounting plate 65 to move the cutting drive motor 66 and the circular cutting blade 67 along the electric guide rail 62, thereby realizing the cutting of the covering material between the sleeve plates conveyed by the conveying mechanism. Under the condition that the cutting direction is set at an obtuse angle to the conveying direction, the circular cutting blade 67 and the sleeve plate are relatively stationary in the conveying direction of the conveying mechanism, which can ensure that the cut surface is straight rather than oblique, achieving one-time cutting without the need for subsequent manual correction. At the same time, the cutting drive motor 66 and the circular cutting blade 67 can be adjusted longitudinally by the vertical telescopic cylinder 64, thereby accommodating the cutting of covering materials of different thicknesses of sleeve plates.
[0020] Two guide rods 69 are provided on the top of the inverted L-shaped mounting plate 65. The tops of the two guide rods 69 pass through the mounting base 63 and are slidably assembled with the mounting base 63. The two guide rods 69 are arranged parallel to and symmetrically on both sides of the vertical telescopic cylinder 64. When the vertical telescopic cylinder 64 drives the cutting drive motor 66 and the circular cutting blade 67 to adjust longitudinally, the two guide rods 69 provide longitudinal guidance, ensuring the stability of the longitudinal adjustment.
[0021] The circular cutting blade 67 is detachably connected to the output shaft of the cutting drive motor 66, facilitating its replacement. The circular cutting blade 67 is made of alloy steel with a blade angle of 30°-45°. This alloy steel material provides high hardness and wear resistance, allowing it to maintain its sharpness for extended periods. The specific blade angle range helps to cut into materials more easily, resulting in cleaner cut edges. A protective cover 68 is fitted over the circular cutting blade 67. The cover 68 is detachably mounted on the L-shaped mounting plate 65, exposing the bottom of the circular cutting blade 67. This design protects the circular cutting blade 67 without interfering with its cutting action.
[0022] The automatic cutting mechanism also includes a PLC controller, which is located on one side of the electric guide rail 62. The output of the PLC controller is connected to the controlled ends of the conveying mechanism, the electric guide rail 62, the vertical telescopic cylinder 64, and the cutting drive motor 66, respectively. The PLC controller realizes automatic control of the cutting process by controlling the conveying mechanism, the electric guide rail 62, and the cutting drive motor 66. The PLC controller also adjusts the cutting height of the cutting drive motor 66 and the circular cutting blade 67 by controlling the vertical telescopic cylinder 64.
[0023] In use, the electric guide rail 62 and the cutting drive motor 66 work together to enable the circular cutting blade 67 to cut the outer material between the two sleeve plates at an angle to the conveying direction, achieving a straight cut. The cutting drive motor 66 and the circular cutting blade 67 can be longitudinally adjusted by the vertical telescopic cylinder 64 to adapt to sleeve plates of different thicknesses.
