Description

Technical Field

[0001] This utility model relates to the technical field of dispensing grooves, and in particular to a dispensing groove for use on phototherapy masks. Background Technology

[0002] In numerous industrial production processes, dispensing is widely used. The dispensing tank, as a key component of dispensing equipment, directly impacts dispensing quality and production efficiency. Currently available dispensing tanks suffer from several drawbacks. Their rectangular cross-section leads to uneven glue flow, resulting in unstable dispensing volumes and affecting product quality. Furthermore, glue overflow is prone to occur during dispensing, wasting glue, potentially contaminating production equipment and the work environment, and requiring significant manpower and time to clean up. These issues urgently need improvement. Utility Model Content

[0003] The present invention aims to provide a dispensing tank with a guide channel and an anti-overflow design, which solves the problems of uneven glue flow and glue overflow in existing dispensing tanks, improves dispensing accuracy and production efficiency, and reduces production costs and maintenance difficulty.

[0004] The purpose of this utility model is achieved as follows:

[0005] A dispensing channel for phototherapy masks includes a guide channel that is wider at the top and narrower at the bottom. An overflow collection groove is provided on the first sidewall of the guide channel. The guide channel's shape allows the adhesive to flow quickly and evenly towards the dispensing port, improving adhesive flowability, ensuring uniform and accurate dispensing, and enhancing dispensing quality. The structure of the guide channel guides the adhesive to be distributed quickly and evenly within the channel, preventing adhesive accumulation and dead zones, ensuring a stable and uniform adhesive supply during dispensing. When there is excessive adhesive in the guide channel, the excess adhesive flows into the overflow collection groove, ensuring uniform overflow speed and flow rate and preventing excessive overflow.

[0006] The present invention can be further improved in the following ways.

[0007] The cross-section of the flow channel is trapezoidal. This shape allows the glue to flow quickly and evenly to the outlet.

[0008] The width b of the top of the guide channel ranges from 2.1mm to 3mm, the width c of the bottom of the guide channel ranges from 0.9mm to 1.4mm, and the depth a of the guide channel ranges from 3.2mm to 4.2mm.

[0009] The bottom of the second sidewall of the guide channel is rounded. This rounded corner allows the glue to flow to the first sidewall of the guide channel.

[0010] The top of the second sidewall of the guide channel is provided with a chamfer, and the overflow collection groove is provided on the first sidewall of the guide channel.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) The guide channel of this utility model is wide at the top and narrow at the bottom. This shape allows the glue to flow quickly and evenly to the outlet, improving the fluidity of the glue, ensuring uniform and accurate dispensing, and improving the dispensing quality. The structure of the guide channel can guide the glue to be distributed quickly and evenly in the guide channel, avoiding the accumulation of glue in the guide channel and the generation of dead flow corners, ensuring a stable and uniform glue supply during the dispensing process.

[0013] (2) The design of the glue overflow collection tank of this utility model effectively prevents glue overflow from the overflow path in two ways, avoids glue waste and pollution to the production environment, reduces cleaning work and lowers maintenance costs.

[0014] (3) The stable glue flow and anti-overflow function of this utility model ensure the smooth progress of the dispensing process, reduce production interruptions and product defect rates caused by glue problems, and improve production efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1, as Figures 1 to 8As shown, a phototherapy mask includes a cover 2 and a mask body 1. The cover 2 is bonded to the outer surface of the mask body 1. The outer periphery of the outer surface of the mask body 1 is provided with an adhesive groove. The adhesive groove includes a guide groove 3. The guide groove 3 is wide at the top and narrow at the bottom. An overflow collection groove 4 is provided on the first side wall of the guide groove 3.

[0025] This is a more specific technical solution of the present invention.

[0026] The cross-section of the guide channel 3 is trapezoidal.

[0027] The width b of the top of the guide channel 3 ranges from 2.1mm to 3mm, the width c of the bottom of the guide channel 3 ranges from 0.9mm to 1.4mm, and the depth a of the guide channel 3 ranges from 3.2mm to 4.2mm.

[0028] The bottom of the second side wall of the guide channel 3 is provided with a rounded corner 5.

[0029] The top of the second sidewall of the guide channel 3 is provided with a chamfered angle 6, and the overflow adhesive collection groove 4 is provided on the first sidewall of the guide channel 3.

[0030] When the dispensing machine dispenses adhesive into the dispensing tank of this invention, the adhesive flows into the guide channel 3. The shape of the guide channel 3 allows the adhesive to flow quickly and evenly towards the dispensing port, improving adhesive flowability, ensuring uniform and accurate dispensing, and improving dispensing quality. Then, the worker or machine places the cover 2 onto the outer surface of the cover 1. Some adhesive flows into the overflow collection groove 4, and the outer periphery of the cover 2 adheres to the adhesive in the dispensing tank, thus bonding the cover 2 to the outer surface of the cover 1.
