Description

Technical Field

[0001] This invention relates to the field of coating machines, and particularly to a gluing coating machine with feed adjustment. Background Technology

[0002] Coating equipment is used to coat paint or other fluid materials onto various substrates. It typically consists of a feeding system, a coating system, and a heating and drying system. The feeding system usually includes a storage tank and a conveying system for transporting the paint from the storage tank to the coating system. Coating machines are widely used in printing, packaging, construction, furniture, and other fields, and can be used to coat various types of substrates such as paper, fabric, plastics, and metals. Different feeding coating machines have different parameters such as coating speed and coating thickness, which can be selected according to specific production needs.

[0003] The colloid is applied to the substrate using a coating equipment. Due to the high viscosity and poor flowability of the colloid, it is often applied using a gap coating method. The coating is applied to the substrate and then scraped off the excess as it passes through the gap between the colloid and the substrate using a "knife" or baffle. This method can be used for high viscosity coatings and very high coating weights.

[0004] The existing technology also has the following drawbacks:

[0005] When extruding colloid onto a substrate, the colloid is often supplied through a pipeline, continuously feeding the substrate. However, the feeding position of the pipeline is singular. Although the subsequent scraper will spread the colloid evenly, some areas with insufficient feeding, such as the sides of the substrate far from the feeding pipeline, still have problems such as insufficient colloid and thin colloid thickness. Some feeding devices cannot adjust the feeding length. When the width of the substrate changes, they cannot be adjusted according to the width of the substrate, which can easily lead to the feeding length being greater than the width of the substrate. The colloid is fed onto the conveyor belt or conveyor roller, resulting in colloid contamination of the substrate. Some devices that use the reciprocating movement of the feeding component to evenly feed the colloid onto the substrate also cannot adjust the stroke of the reciprocating movement according to the width of the substrate.

[0006] Therefore, this application provides an adhesive coating machine with feed adjustment to meet the requirements. Summary of the Invention

[0007] The purpose of this application is to provide a coating machine with feed adjustment, wherein the distance between the two side plates is a reciprocating motion space, and the position of the two side plates is adjusted to change the length of the reset motion space, so that the reciprocating motion of the feed head can be between the two side plates and changes with the adjustment of the position of the two side plates, so that the feed head can feed more evenly to feed grooves of different lengths and coat the substrates of different widths with adhesive more evenly.

[0031] In summary, the technical effects and advantages of this invention are as follows:

[0032] 1. In this invention, when the positions of the two side plates change, when the feeding head moves to the reversing area of ​​the side plate position, the driving gear on the corresponding side drives the adjusting screw to rotate through the linkage gear and transmission gear, so that the adjusting gear moves from one driving gear to the position of the other driving gear and meshes. The two adjusting gears rotate in opposite directions, so that the direction of the adjusting gear changes, the direction of the moving screw driven by the adjusting gear changes, and the feeding head moves in the opposite direction. When it moves to another reversing area, the rotation direction of the moving screw is changed again through another driving gear, linkage gear and transmission gear. The distance between the two side plates is the reciprocating motion space. The adjustment of the positions of the two side plates changes the length of the reset motion space, so that the reciprocating motion of the feeding head can be between the two side plates and changes with the adjustment of the positions of the two side plates, so that the feeding head feeds the material more evenly to the feeding groove of different lengths and coats the substrate of different widths with colloid more evenly.

[0033] 2. In this invention, the colloid is extruded into the feeding groove between the two side plates through the feeding head. The colloid from the two feeding grooves falls onto the substrate. By adjusting the position of the two side plates, the length of the colloid falling from the feeding groove onto the substrate can be adjusted, thereby matching substrates of different widths. This prevents the need to replace the feeding groove with one of the same length when the width of the substrate becomes smaller, saving time and effort. Through the reciprocating motion of the feeding head, the colloid is extruded into the feeding groove during the reciprocating motion, making the colloid in the feeding groove more uniform and the colloid falling onto the substrate more evenly, resulting in a better colloid coating effect.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example: Reference Figures 1-12 The adhesive coating machine shown includes a conveyor belt 1, a fixed shell 2 above the conveyor belt 1, a feeding trough inside the fixed shell 2, a feeding head 3 inside the feeding trough, and the feeding head 3 is capable of squeezing adhesive into the feeding trough.

[0050] The feeding trough is equipped with two side plates 4, and a reciprocating motion space is formed between the two side plates 4. A moving screw 51 is installed in the reciprocating motion space.

[0051] The feed head 3 is threadedly engaged with the moving screw 51, and the forward and reverse rotation of the moving screw 51 is used to drive the main body to perform reciprocating linear motion in the reciprocating motion space;

[0052] The trajectory of the feed head 3 in one unidirectional motion in the reciprocating motion space includes two reversing regions located at both ends of the reciprocating motion space and a transition region in the middle;

[0053] A linkage gear 52 is provided in each reversing area;

[0054] The feed head 3 is equipped with a direction adjustment component 6, which includes an adjustment gear 61 and an adjustment screw 62. The adjustment screw 62 rotates forward and backward to drive the adjustment gear 61 to perform linear reciprocating motion, and the adjustment gear 61 rotates forward and backward to drive the moving screw 51 to rotate forward and backward.

[0055] Both sides of the feed head 3 are respectively provided with a drive gear 53 and a transmission gear 54, and the drive gears 53 on both sides rotate in opposite directions.

[0056] The transmission gear 54 rotates to drive the adjusting screw 62 to rotate;

[0057] When the feed head 3 is in the transition zone, the transmission gears 54 on both sides are in a disengaged state from the corresponding drive gears 53.

[0058] When the feed head 3 enters the reversing area at either end from the transition area, the transmission gear 54 on the side corresponding to that end switches from the disengaged state with the corresponding drive gear 53 to the transmission state. The transmission gear 54 on one side rotates, and ensures that the direction of rotation of the adjusting screw 62 changes once every time the feed head 3 enters the reversing area.

[0059] During the process of the adjusting screw 62 rotating once in one direction, the adjusting gear 61 can be translated from the meshing position with the drive gear 53 on one side to the meshing position with the drive gear 53 on the other side, causing the direction of the adjusting gear 61 to change.

[0060] The conveyor belt 1 moves the substrate from below the feeding trough. The rotation of the moving screw 51 drives the feeding head 3 to move. The forward and reverse rotation of the moving screw 51 causes the feeding head 3 to reciprocate within the feeding trough. During this reciprocating movement, the feeding head 3 extrudes colloid into the feeding trough. The colloid falls onto the substrate through the feeding trough. When the width of the substrate on the conveyor belt 1 changes, the position of the two side plates 4 is adjusted to adjust the length of the colloid falling from the feeding trough, ensuring that the length of the colloid falling onto the substrate matches the substrate. The adjusting gear drives the moving screw 51 to rotate. When the feeding head 3 moves from the transition area to the reversing area within the reciprocating space, the drive gear 53 meshes with the linkage gear 52, and the linkage gear 52 meshes with the transmission gear 54. The drive gear 53 drives the linkage gear 52 to rotate, and the linkage gear 52 drives the transmission gear 54 to rotate. The transmission gear 54 drives the adjusting screw 62 to rotate, causing the adjusting gear 61 to translate. The adjusting gear 61 moves from a position meshed with one drive gear 53 to a position meshed with another drive gear 53. At the engagement position, because the two drive gears 53 rotate in opposite directions, the adjusting gear 61 moves and meshes with the other drive gear 53. After the adjusting gear 61 rotates in the opposite direction, the adjusting gear 61 drives the moving screw 51 to rotate in the opposite direction, causing the feed head 3 to move to the reversing area and then move in the opposite direction to another reversing area. When it moves to the other reversing area, because the drive gears 53 on both sides of the feed head 3 rotate in opposite directions, the corresponding drive gear 53 drives the adjusting screw 62, causing the adjusting gear 61 to change the meshing drive gear 53 again. The rotation of the adjusting gear 61 changes again, and the moving direction of the feed head 3 changes again. This causes the feed head 3 to change its moving direction every time it moves to the reversing area, so that the feed head 3 moves back and forth in the reciprocating motion space. The reciprocating motion space is the distance between the two side plates 4. Adjusting the position of the two side plates 4 can adjust the length of the reciprocating space, thereby adjusting the length of the reciprocating movement of the feed head 3, so that the length of the feed matches the width of the substrate.

[0061] The colloid is extruded into the feeding groove between the two side plates 4 through the feeding head 3. The colloid from the two feeding grooves falls onto the substrate. The length of the colloid falling onto the substrate from the feeding groove can be adjusted by adjusting the position of the two side plates 4, so as to match substrates of different widths. This prevents the need to replace the feeding groove with one of the same length when the width of the substrate becomes smaller, saving time and effort. Through the reciprocating motion of the feeding head 3, the colloid is extruded into the feeding groove during the reciprocating motion, making the colloid in the feeding groove more uniform and the colloid falling onto the substrate more evenly, resulting in a better colloid coating effect.

[0062] When the positions of the two side plates 4 change, and the feeding head 3 moves to the reversing area of ​​the side plate 4, the corresponding drive gear 53 drives the adjusting screw 62 to rotate through the linkage gear 52 and the transmission gear 54, causing the adjusting gear 61 to move from one drive gear 53 to the other drive gear 53 and engage. The two adjusting gears 61 rotate in opposite directions, thus changing the direction of the adjusting gear 61. The moving screw 51 driven by the adjusting gear 61 changes direction, and the feeding head 3 moves in the opposite direction. When it moves to another reversing area, the rotation direction of the moving screw 51 is changed again through another drive gear 53, linkage gear 52 and transmission gear 54. The distance between the two side plates 4 is the reciprocating motion space. The adjustment of the positions of the two side plates 4 changes the length of the reset motion space, so that the reciprocating motion of the feeding head 3 can be between the two side plates 4 and changes with the adjustment of the positions of the two side plates 4. This makes the feeding head 3 feed more evenly to feeding grooves of different lengths and coat the substrates of different widths with adhesive more evenly.

[0063] Furthermore, referring to Figures 1-12 The feed head 3 is also equipped with a drive assembly 7, which includes a drive motor 71, a forward shaft 72 and a reverse shaft 73. Two drive gears 53 are respectively fixedly installed on the forward shaft 72 and the reverse shaft 73.

[0065] The drive motor 71 drives the forward shaft 72 and the reverse shaft 73 to rotate, and the rotation directions of the forward shaft 72 and the reverse shaft 73 are opposite. One of the two drive gears 53 is fixedly installed on the forward shaft 72 and the other is fixedly installed on the reverse shaft 73, so that the rotation directions of the two drive gears 53 are opposite. When the feed head 3 moves to the side plate 4, the linkage gear 52 is inserted between the meshing gear 55 and the transmission gear 54 and meshes with the meshing gear 55 and the transmission gear 54. When the drive motor 71 drives the forward shaft 72 and the reverse shaft 73 to rotate, the forward shaft 72 and the reverse shaft 73 respectively drive the corresponding meshing gear 55 to rotate, and the two meshing gears 55 rotate in opposite directions. The meshing gear 55 drives the linkage gear 52 to rotate, the linkage gear 52 drives the transmission gear 54 to rotate, and the transmission gear 54 drives the adjusting screw 62 to rotate.

[0066] The ends of the meshing gear 55, the transmission gear 54, and the linkage gear 52 are uniformly set with involute teeth.

The input gear drives the reverse shaft 73 to rotate, and the direction of rotation of the reverse shaft is opposite to that of the output shaft 74.

[0074] When the adjusting screw 62 rotates, the adjusting block 9 moves on the adjusting screw 62, and the adjusting block 9 moves the adjusting gear 61 on the rotating rod 84, so that the adjusting gear 61 moves from being engaged with one driving gear 53 to being engaged with another driving gear 53.
