Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental protection bag processing technology, and in particular relates to a water-based adhesive spraying device for processing environmental protection bags. Background Technology
[0002] Eco-friendly bags are bags used to hold and carry items. Current eco-friendly bag production typically involves using a water-based adhesive spraying device to apply glue to the areas of the bag that need to be glued. Existing spraying devices include a C-shaped base with a glue storage tank fixedly connected to its top. A glue pump is fixedly connected to one side of the top of the C-shaped base, with its input end connected to the glue storage tank and its output end connected to a corrugated pipe. While this existing spraying device can hold the bag in place before spraying glue using a pressure tube, when the eco-friendly bag is placed on a processing table and has wrinkles, the pressure tube tends to press down the wrinkles as well, resulting in uneven glue application.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. As shown in Figures 1 and 2, a water-based adhesive spraying device for processing eco-friendly bags includes a processing table 1 and an adhesive tank 2 disposed on one side of the processing table 1. A cylinder 11 and an adhesive delivery pump 3 are fixedly installed on the upper part of the processing table 1. The output rod of the cylinder 11 passes through the upper side of the processing table 1. The inlet end of the adhesive delivery pump 3 is connected to a valve pipe installed at the outlet of the adhesive tank 2. A spraying pipe assembly 5 is installed at the lower end of the output rod of the cylinder 11. A pressure plate assembly 6 and a movable spreading plate assembly 7 are installed inside the processing table 1. The spraying pipe assembly 5 includes a positioning pipe 51. A bracket 52 is fixedly installed on the upper part of the positioning pipe 51. A connecting frame 53 is fixedly installed on the upper part of the bracket 52. A connecting pipe 54 is fixedly installed through the middle of the bracket 52. The upper end is hollow, and the upper end of the positioning tube 51 is fixedly installed with a glue nozzle 55. The lower end of the positioning tube 51 is fixedly installed with a laser emitter 56 in a triangular distribution. The upper end of the connecting frame 53 is fixedly installed with the output rod of the cylinder 11. The cylinder 11 drives the positioning tube 51, the bracket 52 and the connecting frame 53 to move downward, so that the positioning tube 51 presses down the flattened environmental protection bag. The glue delivery pump 3 delivers the glue in the glue tank 2 to the glue nozzle 55 through the connecting hose 4 and the connecting pipe 54. The glue nozzle 55 sprays the glue onto the environmental protection bag. The laser emitted by the laser emitter 56 shines on the environmental protection bag, so that the user can judge the position of the glue nozzle 55 based on the laser position, which plays the role of positioning the glue spraying position.
[0021] In this implementation plan, in conjunction with the appendix Figure 3 As shown, the pressure plate assembly 6 includes a pressure plate 61, with a rubber layer 62 glued to the lower part of the pressure plate 61. A handle 63 is fixedly installed on the upper front side of the pressure plate 61, and a connector 64 is installed on the rear pin of the pressure plate 61. The user first places the environmental protection bag in the processing table 1, opens the pressure plate 61 through the handle 63, lays one end of the environmental protection bag flat under the pressure plate 61, and keeps pressing down the pressure plate 61 so that the rubber layer 62 presses down and fixes the environmental protection bag.
[0022] In this implementation plan, in conjunction with the appendix Figure 4As shown, the movable display plate assembly 7 includes an electric guide rail 71 and a slide rail 72. A U-shaped component 73 is fixedly installed at the front of the slider of the electric guide rail 71. A display plate 74 is arranged between the electric guide rail 71 and the slide rail 72. The front and rear ends of the display plate 74 are cylindrical, and connecting blocks 75 are sleeved on both ends of the display plate 74. The connecting block 75 on the rear side is connected to the U-shaped component 73 by a pin. A support 76 is fixedly installed at the slider of the slide rail 72. The connecting block 75 on the front side rests in a groove opened at the upper end of the support 76, and the connecting block 75 on the front side is fixed to the support 76 by a buckle 77. The user can loosen the buckle. The bolts connecting the flat plate 74 and the connecting block 75 are fixed. The angle of the flat plate 74 is adjusted so that it is tilted, thereby making the gap between the flat plate 74 and the processing table 1 match the thickness of the eco-friendly bag. After adjustment, the bolts connecting the flat plate 74 and the connecting block 75 are fixed. The flat plate 74 is located on the side close to the pressure plate 61. The user opens the buckle 77 and flips the flat plate 74 upward to facilitate placing the eco-friendly bag between the flat plate 74 and the processing table 1. After the eco-friendly bag is placed, the connecting block 75 and the support 76 are fixed using the buckle 77. The electric guide rail 71 drives the flat plate 74 to move and flatten the eco-friendly bag.
[0023] In this embodiment, specifically, a connecting hose 4 is fixedly installed between the outlet end of the glue delivery pump 3 and the connecting pipe 54.
[0024] In this embodiment, specifically, the electric guide rail 71 and the connector 64 are fixedly installed side by side on the vertical inner wall of the processing table 1.
[0025] In this embodiment, specifically, the slide rail 72 is fixedly installed on the lower front side of the processing table 1.
[0026] In this embodiment, specifically, the upper end of each connecting block 75 is provided with bolts for locking the unfolding plate 74.
[0027] In this embodiment, specifically, the liquid inlet end of the glue nozzle 55 is fixedly installed at the lower end of the connecting pipe 54.
[0028] Working principle
[0029] In this invention, the glue delivery pump 3, the laser emitter 56, and the electric guide rail 71 are all connected to an external industrial control device.
