Description

Technical Field

[0001] The invention relates to a glue dispensing device, in particular to a glue dispensing device for a packaging paper tray. Background Art

[0002] In the modern packaging industry, paper trays (such as paper trays or stands for food, electronic products, etc.) are increasingly used. Paper trays not only provide an environmentally friendly and cost-effective packaging solution, but also protect products from physical damage during transportation and storage. In order to ensure that the product can be safely and firmly placed in the paper tray and maintain a good display effect, it is usually necessary to use glue or other adhesives to fix the product to the paper tray.

[0003] At present, in the process of packaging paper trays and products, paper trays are usually placed on a conveyor belt manually, transported by the conveyor belt, and then transported to the glue dispensing area, where they are glued with an adhesive. The products are then placed in the glue dispensing area for gluing. However, due to the different widths of paper trays in different batches, when replacing paper trays in different batches, the position of the glue dispensing gun and the position of the limit structure need to be adjusted in turn. Two devices need to be adjusted separately, which makes the operation more cumbersome and reduces production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0028] A packaging paper tray glue dispensing device, such as Figure 1-Figure 4 As shown, it includes a glue dispensing workbench 1, a side frame 2, a belt conveyor group 3, a baffle 4, a connecting frame 5, a glue dispensing mechanism, a limiting mechanism and a synchronous moving mechanism. The side frames 2 are installed on the left and right sides of the top of the glue dispensing workbench 1, and the belt conveyor group 3 is installed between the side frames 2 on both sides. The baffles 4 are connected to the front and back sides of the top of the glue dispensing workbench 1. The baffles 4 on both sides respectively block the front and back sides of the belt conveyor group 3, thereby blocking the paper tray that needs to be glued and preventing the paper tray from falling from the belt conveyor group 3. A connecting frame 5 is installed on the right side of the top of the glue dispensing workbench 1. A glue dispensing mechanism for gluing the paper tray is provided on the connecting frame 5. A limiting mechanism for limiting the paper tray is provided between the baffle 4 and the connecting frame 5, and a synchronous moving mechanism is provided between the limiting mechanism and the glue dispensing mechanism.

[0029] like Figure 2-Figure 4 As shown, the glue dispensing mechanism includes a slider 61, a glue injection box 62, a glue gun 63 and a glue feeding tube 64. The sliders 61 are slidably connected to the front and rear sides of the connecting frame 5. The glue gun 63 is installed on the slider 61. The glue gun 63 can apply glue on the paper tray. The glue dispensing workbench 1 is installed with a glue injection box 62 at the lower part. The glue injection box 62 and the glue gun 63 are connected with a glue feeding tube 64, so that the glue injection box 62 can transport glue to the glue gun 63 through the glue feeding tube 64, so that the glue gun 63 can perform glue dispensing.

[0030] like Figure 2 and Figure 3As shown, the limiting mechanism includes a bidirectional screw 71, a rotating wheel 72, a sliding frame 73, a swinging plate 74 and a limiting plate 75. The lower part of the connecting frame 5 is rotatably connected to the bidirectional screw 71, and both ends of the bidirectional screw 71 are connected to the rotating wheels 72. The right sides of the two baffles 4 are slidably connected to the sliding frames 73, and the sliding frames 73 can slide back and forth along the baffle 4. The two sliding frames 73 are respectively matched with the front and rear sides of the bidirectional screw 71, so that the bidirectional screw 71 can drive the sliding frame 73 to move back and forth through the threads when rotating, and the two baffles 4 are close to each other. The right part of the near side is rotatably connected with a swing plate 74, and the left side of the swing plate 74 is rotatably connected to a limit plate 75. The two limit plates 75 are slidably matched with the two sliding frames 73 respectively. The sliding frames 73 can slide left and right on the limit plates 75. When the sliding frames 73 move back and forth, they can drive the limit plates 75 to move back and forth, and the swing plate 74 will swing with the movement of the limit plates 75. When placing a paper tray, the paper tray will be squeezed by the two swing plates 74 and finally sent between the two limit plates 75, and the paper tray will be limited by the limit plates 75.

[0031] like Figure 2-Figure 4 As shown, the synchronous movement mechanism includes a connecting rod 81, an adjusting screw 82 and a knob 83. The tops of the two sliding frames 73 are connected to the connecting rod 81, and the two sliders 61 are rotatably connected to the adjusting screws 82. The two connecting rods 81 are respectively threadedly matched with the two adjusting screws 82, so that the adjusting screw 82 can drive the adjusting screw 82 to move through the thread between the adjusting screw 82 and the connecting rod 81 when rotating, thereby driving the slider 61 to move and adjusting the distance between the slider 61 and the connecting rod 81. The adjusting screw 82 is connected to the knob 83, and the knob 83 can be used to more conveniently operate the rotation of the adjusting screw 82.

[0032] When it is necessary to perform glue dispensing on the paper support, the present device can be used. When in use, the paper support is first placed on the belt conveyor group 3. After placement, the belt conveyor group 3 can be controlled to operate to transport the paper support. During the transportation process, the paper support will contact the swing plates 74 on both sides, and the paper support will be guided by the swing plates 74 until the paper support is transported to the limit plates 75 on both sides. The paper support can then be limited by the limit plates 75. At this time, the paper support is also located below the glue gun 63, and then the glue gun 63 can be controlled to operate to apply glue on the paper support, so that glue can be applied to the paper support while the paper support is being transported, so as to achieve the effect of glue dispensing on the paper support. During the operation, if the batches of paper support are different When the width changes, the rotating wheel 72 can be rotated to drive the bidirectional screw 71 to rotate. When the bidirectional screw 71 rotates, it can drive the two sliding frames 73 to move closer to or away from each other. When the sliding frame 73 moves, it can drive the limit plate 75 and the connecting rod 81 to move, so as to adjust the distance between the two limit plates 75. When the connecting rod 81 moves, it can drive the slider 61 to move by adjusting the screw 82, so as to adjust the position of the glue gun 63, so as to achieve the effect of synchronously adjusting the position of the limit plate 75 and the glue gun 63. In this way, the present device can be used to perform glue dispensing on the paper support, and when replacing paper supports of different sizes, only the limit plate 75 needs to be adjusted, and the position of the glue gun 63 can be synchronously adjusted, which is more convenient when performing adjustment operations.

[0033] like Figure 5-Figure 8 As shown, a flattening mechanism is also included, and the flattening mechanism includes a side plate 91, a guide sleeve 92, a sleeve 93, a piston rod 94 and a pressure wheel 95. The left part of the side away from each other of the two baffles 4 is connected to the side plate 91, and the upper part of the side plate 91 is slidably connected to the guide sleeve 92, and the guide sleeve 92 can slide up and down along the side plate 91. An elastic member 96 is connected between the guide sleeve 92 and the side plate 91, and the elastic member 96 is a pressure spring. The elastic member 96 can exert pressure on the guide sleeve 92. The guide sleeve 92 is connected with a sleeve 93 to provide downward pressure. The two guide sleeves 92 are slidably connected with a piston rod 94 on one side where the two guide sleeves 92 are close to each other. The two piston rods 94 are rotatably connected with a pressure wheel 95 on one side where the two piston rods 94 are close to each other. When the elastic member 96 applies downward pressure to the guide sleeve 92, the guide sleeve 92 can drive the pressure wheel 95 to move downward through the sleeve 93 and the piston rod 94. When the paper support and the material move to the bottom of the pressure wheel 95, the pressure wheel 95 can squeeze the material and press the material and the paper support together.

[0034] After the paper tray is coated with glue, the belt conveyor group 3 continues to convey the paper tray. During the conveying process, the material can be covered on the paper tray. After covering, the paper tray continues to be conveyed. During the conveying process, the material will contact with the pressure wheel 95 and squeeze the pressure wheel 95 to move upward. The elastic member 96 is in a compressed state and can apply downward pressure to the guide sleeve 92, the sleeve 93, the piston rod 94 and the pressure wheel 95, so that the pressure wheel 95 presses the material. Subsequently, during the conveying process, the pressure wheel 95 can press the material and the paper tray together to complete the pressing process after the paper tray is coated with glue. In this way, the pressing process of the paper tray and the material can be automatically realized.

[0035] like Figure 5-Figure 8 As shown, it also includes a transmission mechanism, which includes a sliding plate 101, a convex shaft 102, a cylinder body 103, an infusion tube 104 and a piston rod 105. The left side of the connecting frame 5 is slidably connected to the sliding plate 101, and the sliding plate 101 can slide up and down along the connecting frame 5. The sliding plate 101 is provided with inclined grooves on both the front and rear sides. The left sides of the two sliders 61 are connected to the convex shafts 102, and the convex shafts 102 pass through the left side of the connecting frame 5 and can slide forward and backward along the connecting frame 5. The shaft 102 is respectively located in the two inclined grooves, and the front and rear sides of the left side of the connecting frame 5 are connected to the cylinder body 103. The cylinder body 103 is slidably connected with a piston rod 105. The piston rod 105 is connected to the top of the sliding plate 101 so that the sliding plate 101 can drive the piston rod 105 to move when it moves. An infusion tube 104 is connected between the bottom of the cylinder body 103 and the sleeve 93, and the sleeve 93, the infusion tube 104 and the cylinder body 103 are all filled with liquid.

[0036] When adjusting the position of the glue gun, the movement of the slider 61 will drive the convex shaft 102 to move. The convex shaft 102 moves along the inclined groove. When moving along the inclined groove, the convex shaft 102 squeezes the inclined groove, thereby driving the sliding plate 101 to move up and down. When the sliding plate 101 moves, it can drive the piston rod 105 to move. When the piston rod 105 moves upward, it can draw the liquid in the sleeve 93 into the cylinder body 103 through the infusion tube 104, so that the two piston rods 1 94 are away from each other. At this time, the two sliders 61 are also in a state of being away from each other. When the piston rod 105 moves downward, the liquid in the cylinder 103 can be injected into the sleeve 93 through the infusion tube 104, thereby squeezing the two piston rods 1 94 close to each other. At this time, the two sliders 61 are also in a state of being close to each other, so that the piston rod 1 94 can move synchronously with the movement of the slider 61, and the pressure wheel 95 can move with the movement of the glue gun 63. There is no need for additional manual adjustment of the glue gun 63, which is more convenient to operate.

[0037] like Fig. 9 and Fig.10As shown, it also includes a collecting frame 111 and an electric push rod 112. The electric push rod 112 is installed at the lower part of the connecting rod 81, and the collecting frame 111 is connected to the telescopic rod of the electric push rod 112. The collecting frame 111 is located below the glue gun 63. After the glue gun 63 finishes gluing, the glue gun 63 is controlled to be closed. At this time, the telescopic rod of the electric push rod 112 can be controlled to extend to drive the collecting frame 111 to move to the bottom of the glue gun 63. The glue overflowing from the glue gun 63 is collected by the collecting frame 111 to prevent the glue from dripping onto the belt conveyor group 3.

[0038] like Fig.11 As shown, it also includes a conveying wheel 12. The sides of the two limit plates 75 that are close to each other are evenly spaced and rotated and connected with multiple conveying wheels 12. When the paper holder moves on the belt conveyor group 3, the edge of the paper holder will contact the conveying wheel 12. The conveying wheel 12 can reduce the friction of the paper holder when it moves.
