Description
Technical Field
The utility model relates to the technical field of dispensing, in particular to a dispensing head glue breaking device.
Background
The two-component dispensing valve is mainly applied to industries such as batteries, electrical elements, communication equipment and the like, and has the functions of filling, sealing, bonding, sealing and the like. When the dispensing valve works, the compressed air is mainly used as power, the two-component glue is extruded to the mixing pipe, and the glue is mixed by the mixing pipe and then falls onto a product through the dispensing head. When the first dispensing is completed and the dispensing valve is closed, a small amount of glue still falls from the dispensing head to form a thread shape due to the property of glue fluid, and if the thread-shaped glue drops to the part outside the product gluing area, the product quality problem can be caused, and the product can be scrapped in severe cases. At present, common processing mode of enterprises is that after gluing is finished, namely after single gluing is finished and a glue dispensing valve is closed, a product can be retracted for a little distance, so that wiredrawing glue is dripped on the coated glue, and although the gluing quality is basically not affected, the following two problems exist in the working state of equipment: 1. because the product needs to be retracted, the single dispensing time is prolonged, and the overall gluing efficiency is affected; 2. when the adhesive tape is taken, only a single adhesive dispensing process can be taken, and the camera cannot take a picture in the rollback process, so that the final adhesive coating state of the product is determined, and uncontrollable factors exist. Under the non-operating condition, still need use independent frictioning ware, strike off unnecessary wire drawing's glue from some gum head, but glue still can remain on the frictioning ware, still need extra instrument to get rid of glue, equipment structure is complicated, and is with high costs.
Disclosure of Invention
In order to solve the problems that in the existing dispensing process, products need to be pulled back due to glue wire drawing, the dispensing efficiency is affected, the glue coating effect cannot be controlled, the equipment structure is complex, and the cost is high, the utility model provides the dispensing head glue breaking device which can effectively prevent glue wire drawing, and the products do not need to be pulled back, so that the dispensing efficiency is improved, and the dispensing head glue breaking device is simple in structure and low in cost.
The technical scheme is as follows: the utility model provides a broken mucilage binding of point gum head is put, its is including the point gum head of connecting the hybrid tube, its characterized in that, the overcoat of point gum head is equipped with the broken gum ware, offered on the broken gum ware at least two orientation the export of point gum head and the flat air outlet of hedging arrangement.
The glue breaker is further characterized by comprising an inner sleeve and an outer sleeve, wherein the inner sleeve is attached to the outer wall of the glue dispensing head, at least two grooves are formed in the bottom end face of the inner sleeve, the bottom inner wall of the outer sleeve is attached to the bottom end face of the inner sleeve to enable the grooves to form the flat air outlet, the whole or part of the flat air outlet is lower than the bottom end face of the glue dispensing head, a cavity communicated with the flat air outlet is formed between the inner sleeve and the outer sleeve, an air inlet pipe joint communicated with the cavity is arranged on the outer wall of the outer sleeve, and compressed air is introduced into the air inlet pipe joint;
the cavity is an annular cavity;
two to six grooves are uniformly formed in the groove;
the bottom opening of the inner sleeve is larger than the outlet of the dispensing head, and the bottom opening of the outer sleeve is larger than the bottom opening of the inner sleeve.
After the utility model is adopted, when the dispensing head finishes one-time dispensing, the glue is rapidly cut off by the air blown out from the opposite-flushing flat air outlet, so that the wire drawing at the outlet of the dispensing head is avoided, the product does not need to be pulled back, the product can be continuously conveyed forwards for dispensing, the dispensing efficiency is effectively improved, the product structure is simple, and the cost is reduced.

Detailed Description
See fig. 1 to 5, a broken mucilage binding of point gum head is put, and it is including the point gum head 2 of connecting hybrid tube 1, and the overcoat of point gum head 2 is equipped with the broken gum ware 3, has offered a plurality of export towards point gum head 2 and the flat air outlet 4 that the hedging was arranged on the broken gum ware 3, generally sets up two, four or six, adopts four structures in this embodiment, can ensure to blow out disconnected effect.
The glue breaker 3 comprises an inner sleeve 5 and an outer sleeve 6, wherein the inner sleeve 5 is attached to the outer wall of the glue dispensing head 2, four grooves 7 are formed in the bottom end face of the inner sleeve, the grooves 7 are milled by a milling cutter, the bottom inner wall of the outer sleeve 5 is attached to the bottom end face of the inner sleeve 5 to enable the grooves 7 to form a flat air outlet 4, the flat air outlet 4 can be completely or partially lower than the bottom end face of the glue dispensing head 2, in the embodiment, all the adopted air outlet is lower than the bottom end face, namely, all the air outlet is exposed below the glue dispensing head 2, the cutting effect is ensured, an annular cavity 8 communicated with the flat air outlet 4 is formed between the inner sleeve 5 and the outer sleeve 6, two air inlet pipe joints 9 which are symmetrically arranged and are communicated with the annular cavity 8 are arranged on the outer wall of the outer sleeve 6, and compressed air is introduced into the air inlet pipe joints 9; the bottom opening of the inner sleeve 5 is larger than the outlet of the dispensing head 2, and the bottom opening of the outer sleeve 6 is larger than the bottom opening of the inner sleeve 5.
The working principle is as follows: when dispensing, the dispensing valve is opened, glue is extruded from the dispensing head 2 and dripped on a product, the dispensing valve is closed when dispensing is completed, if no external force is applied, the fluid characteristic of the glue at the moment is that some glue is dripped from the dispensing head 2 to form wiredrawing, when dispensing is completed, compressed air is sent into the air inlet pipe joint 9 and is blown out from the flat air outlet 4 after passing through the annular cavity 8, and the flat air outlet 4 is arranged in a opposite flushing way, and is added with a flat cutter similar to four air, so that the original continuous glue is cut off instantaneously, the lower part of the cut glue is dripped on the product, and wiredrawing does not occur on the upper part of the glue and remains in the dispensing head 2 to prepare for next dispensing.
