Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a dispensing and separating mechanism. Background Art

[0002] In the existing dispensing mechanism, glue flowing out from a dispensing head is dispensed onto a material to be dispensed. However, when some materials, especially flexible binding tapes, are separated from the dispensing head after dispensing, they are easily driven by the adhesive force of the glue and deviate from the original position as the dispensing head moves, affecting the subsequent alignment bonding accuracy and bonding effect. Therefore, a dispensing and separating mechanism that can keep materials such as the binding tape to be dispensed in place after dispensing is needed. Content of the Utility Model

[0018] The following will clearly and completely describe the technical solutions of the embodiments of the present utility model in conjunction with the drawings. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments described in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope protected by the present utility model.

[0019] An embodiment of the present utility model provides a dispensing separation mechanism, as Figures 1 to 4 shown, including a pusher 1, a fixing device, a glue outlet device and a separating member 4. The glue outlet device is fixed on the fixing device, the pushing device drives the fixing device to approach or move away from the workpiece to be bonded, one end of the separating member 4 is fixed on the fixing device, and the other end extends beyond the bottom of the glue outlet device and contacts the workpiece to be bonded to achieve elastic separation.

[0020] The pusher 1 described above is a common pneumatic cylinder, which is connected to an external controller and a gas source. The structure and usage mode of the pneumatic cylinder are well-known prior arts to those skilled in the art and will not be elaborated herein. The pusher 1 is provided with a push rod, and an installation block 11 is fixedly arranged at the bottom of the push rod. An installation hole is arranged at the front part of the installation block 11, and the installation hole is a threaded hole.

[0021] The fixing device includes a fixing frame 2 and a connecting piece. The fixing frame 2 is used to fixedly clamp the glue discharging device. A fixing groove 21 and a clamping hole are arranged on the fixing frame 2. An installation through hole is further arranged at the front part of the fixing frame 2, and the installation through hole is arranged corresponding to the installation hole. The connecting piece is a screw 22. The installation frame is fixedly installed at the front part of the installation block 11 through the screw 22.

[0022] The glue discharging device includes a glue discharging pipe 3, and the top of the glue discharging pipe 3 is connected to a glue discharging mechanism. Specifically, the structure and usage mode of the glue discharging pipe 3 and the glue discharging mechanism are well-known prior arts to those skilled in the art and will not be elaborated herein. The glue discharging pipe 3 is sleeved and fixed in the clamping hole.

[0023] The separating member 4 is an elastic member arranged in a spiral ring shape and has axial compression and recovery capabilities. The bottom ring diameter of the separating member 4 is larger than the top. The top of the separating member 4 is sleeved on the outer wall of the glue discharging pipe 3. The top of the separating member 4 abuts against the bottom of the fixing frame 2. The bottom of the separating member 4 abuts against the bundling belt 5 that bundles the object to be bundled 51.

[0024] During the use process, when the bundling equipment is running, after the bundling belt 5 is wound around the object to be bundled 51, the position of the bundling belt 5 that needs to be glued is corresponding to the lower part of the glue discharging pipe 3. The pusher 1 drives the push rod to move, driving the installation block 11 to move. The fixing frame 2 fixed to the installation block 11 moves downward synchronously. At this time, the glue discharging pipe 3 and the separating member 4 approach the bundling belt 5. The separating member 4 is axially compressed and deformed. After reaching the set position, the glue discharging pipe 3 arranges glue on the bundling belt 5.

[0025] After the dispensing is completed, the pusher 1 drives the mounting block 11 to drive the mounting bracket to move away from the bundling strap 5. At this time, due to the viscosity of the glue itself, the glue outlet pipe 3 and the bundling strap 5 cannot be separated instantaneously, resulting in a tendency for the bundling strap 5 to deviate upward from its original position under the drive of the glue outlet pipe 3. The bottom of the separating member 4 abuts against the bundling strap 5. At the same time, during the upward movement of the fixing bracket 2, the separating member 4 gradually resumes its shape, generating a downward thrust at the bottom, and pushing the bundling strap 5 away from the nozzle position of the glue outlet pipe 3. It is ensured that the bundling strap 5 is not carried away from its original position by the glue, avoiding deviation.

[0026] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0027] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
