Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve pocket dispensing technology, specifically a valve pocket dispensing structure. Background Technology
[0002] In the packaging industry, valve bags are widely used for packaging various materials due to their unique valve design. During the production of valve bags, glue dispensing is a crucial step, affecting the bag's seal and overall quality. Traditional glue dispensing structures often employ fixed patterns, failing to flexibly adjust to the specific needs of each glue dispensing location on the valve bag. This leads to inaccurate dispensing positions, resulting in either too much or too little glue, wasting resources, impacting product quality, and reducing production efficiency. Therefore, a novel valve bag glue dispensing structure is needed. Utility Model Content

[0016] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0019] See Figure 1-3 A valve pocket dispensing structure includes a dispensing roller 2, which is mounted on a worktable via two mounting plates 1 on both sides. The dispensing roller 2 has multiple dispensing ports 21, which are staggered. Sensors 22 are provided on the sides of the multiple dispensing ports 21. A rotating component 3 is rotatably connected to the dispensing roller 2. The rotating component 3 includes a connecting rod 32, which is screwed with multiple knobs 33. Multiple stops 4 corresponding to the dispensing ports 21 are slidably connected to the connecting rod 32. The stops 4 have grooves 41, which are connected to the knobs 33. The sensors 22 are infrared light sensors. During dispensing, the operator can control multiple dispensing ports 21 to dispense adhesive into the valve bag. The dispensing principle of the dispensing roller 2 is the same as that of existing dispensing rollers, which will not be elaborated on here. The staggered setting of the dispensing ports 21 can improve the accuracy of dispensing and avoid excessive dispensing and waste of adhesive. When the operator performs intermittent dispensing, the operator can control the stop block 4 corresponding to the position of the dispensing port 21 to block the sensor 22 next to the dispensing port 21, thereby making the dispensing port 21 inactive. The connection between the sensor 22 and the dispensing port 21 is an electrical connection, which is an existing Internet of Things control technology, and will not be elaborated on here. As described above, when blocking, taking one of the dispensing ports 21 as an example, the operator loosens the knob 33 and then controls the stop block 4 to move towards the sensor 22, so that the connecting rod 32 moves within the annular groove 42 until the stop block 4 blocks the sensor 22. Then, the knob 33 is tightened to fix the stop block 4 and the connecting rod 32, preventing slippage and ensuring the blocking effect of the stop block 4. This achieves intermittent dispensing. Furthermore, the operator can control the opening and closing of multiple dispensing ports 21 as needed, thereby enabling the selection of dense dispensing and intermittent dispensing, achieving dispensing flexibility and ensuring dispensing accuracy, and improving dispensing efficiency.
[0020] In some embodiments, a turntable 31 is welded to each end of the connecting rod 32, and the turntable 31 is rotatably connected to the rotating shaft of the dispensing roller 2. When the operator needs to move the dispensing roller 2, the operator can move the dispensing roller 2 through the turntable 31, and at the same time, the turntable 31 can be connected to the fixing equipment to fix the dispensing roller 2, which is simple and convenient to operate.
[0021] In some embodiments, the end of the stop 4 is provided with a toggle part 43. When the operator wants to control the stop 4 to slide on the connecting rod 32, the stop 4 can be quickly moved by simply toggle the stop 4 with the toggle part 43, avoiding the operator's fingers being scratched by the stop 4 when toggle it, and ensuring the safety of operation.
[0022] In some embodiments, a brush 44 is provided on the side of the stop block 4 near the dispensing roller 2. When there is glue residue after dispensing at the dispensing nozzle 21, the operator can tighten the knob 33 to fix the stop block 4 and the connecting rod 32 so that they cannot slide through the annular groove 42. Then, the turntable 31 is controlled to rotate back and forth, so that multiple stops 4 rotate back and forth on the surface of the dispensing roller 2 along with the connecting rod 32. Thus, the brush 44 on the stop block 4 continuously wipes the glue off the dispensing nozzle 21, which can prevent the dispensing nozzle 21 from becoming blocked.
[0023] In some embodiments, the knob 33 is provided with anti-slip texture on its side. The anti-slip texture can increase the friction between the operator and the knob 33, making it easier and faster for the operator to turn the knob 33, more comfortable to apply force, improving operating efficiency, and ensuring the accuracy of operation.
[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
