Description

Technical Field

[0001] The invention relates to a cup body surface spraying assembly line, in particular to an automatic release device of the cup body spraying assembly line which is automatically released after the cup body surface spraying is completed. Background Art

[0002] At present, in order to improve the grade and quality of products in the thermos cup or pot industry, the product surface needs to be colored to meet the requirements of different consumers for different colors. In order to improve the quality and efficiency of spraying, the spraying and coloring of the surface of the thermos cup or pot is carried out on the spraying assembly line, and each connection station is provided with a cup body clamp for fixing the thermos cup or pot. However, the existing cup body clamp has the following main problems during use: First, since the specifications of the thermos cups or pots produced by each enterprise range from dozens to hundreds, each enterprise needs to be equipped with a cup mouth mold consistent with the type of thermos cup or pot. Since the cup mouth mold is fixed to the cup body clamp through a threaded connection, it needs to be stopped for replacement and disassembly, which is labor-intensive, time-consuming and labor-intensive. It not only affects the production efficiency and normal use of the equipment, but also causes flying paint to enter the cup from the gap if the installation is not flat. Second, the existing cup body clamp is fixed to the cup body by thread rotation, and it needs to be rotated manually to load and unload the cup. It is difficult to align the cup mouth with the clamp during online operation, and there are many operating errors. Each process requires at least two people, or even more, and the work efficiency is low. Third, paint will stick to the paint during the painting process, and it needs to be diluted and washed with chemicals. Removal is inconvenient and not environmentally friendly. Fourth, paint is a toxic and harmful substance. During the spraying process, workers will inhale it from their mouths and noses or absorb it through their skin. Long-term work will lead to occupational diseases. For this reason, many manufacturers and knowledgeable people have carried out development and research, but no ideal product has been launched so far. Summary of the invention

[0003] In order to overcome the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide an automatic release device for a cup spraying line which has a simple and reasonable structure, is easy to install and use, has reliable locking, runs smoothly, and automatically tensions the cup body when installed and automatically separates the cup body when removed.

[0004] The present invention creates a technical solution adopted to solve its technical problems, which includes a guide rail seat, an assembly line guide rail rotating around the guide rail seat, and a cup body clamp fixed on the assembly line guide rail. An automatic release seat is fixed on the guide rail seat, and a release inclined guide rail is provided on the automatic release seat. An arc-shaped buffer spring sheet is provided on the automatic release seat above the release inclined guide rail; the cup body clamp includes an arc-shaped spring sheet, a cup mouth mold, a positioning sleeve, a shield, a spring sleeve, and a central axis. The cup mouth mold is provided with a connecting socket matching the cup body, and the cup mouth mold can be detachably locked on the positioning sleeve. The upper part of the central axis is provided with at least three axially distributed springs. A spring leaf positioning groove and a plurality of circumferentially distributed positioning tooth grooves, the arc-shaped spring leaf is correspondingly installed on the spring leaf positioning groove, the arc-shaped spring leaf is provided with positioning teeth matching with the positioning tooth groove, the positioning sleeve can be axially slidably sleeved on the central shaft and wrap the arc-shaped spring leaf, the upper and lower parts of the arc-shaped spring leaf extend out of the positioning sleeve correspondingly, the spring sleeve is connected to the positioning sleeve through a protective cover, a release spring is provided between the spring sleeve and the central shaft, a release washer matching with the release inclined guide rail is fixed on the spring sleeve, and the arc-shaped spring leaf is positioned on the central shaft through the positioning teeth matching with the corresponding positioning tooth groove when the positioning sleeve moves up and down.

[0005] A further solution created by the present invention is that when the cup body clamp enters the automatic release seat, the friction resistance between the arc spring piece and the cup body is greater than the elastic force of the release spring; when the release washer moves along the release inclined guide rail, the release washer drives the positioning sleeve to move upward along the center axis and the arc spring piece through the spring sleeve and the protective cover, and the friction resistance between the arc spring piece and the cup body gradually decreases; when the elastic force of the release spring is greater than the friction resistance between the arc spring piece and the cup body, the release spring drives the positioning sleeve and the cup mouth mold to bounce upward along the center axis and the arc spring piece through the spring sleeve and the protective cover, and the positioning sleeve causes the head of the arc spring piece to retract and release the lock on the cup body; in the upward bouncing process, the release washer contacts with the arc buffer spring piece and plays a buffering role to prevent the cup body from falling off the cup mouth mold.

[0006] According to a further solution of the present invention, a silicone head is fixed to the head of the arc-shaped spring sheet, wherein an elastic conductive contact is fixed to the head of at least one arc-shaped spring sheet for elastically contacting with the cup body to ensure reliable electrical conduction.

[0007] A further solution created by the present invention is that an inner positioning piece is fixed in the spring sleeve, an outer positioning piece is provided on the central shaft, a release spring is sleeved on the central shaft and arranged between the inner positioning piece and the outer positioning piece, and an upper limit clamp for controlling the travel of the positioning sleeve and the shield is fixed on the central shaft.

[0008] According to a further solution created by the present invention, a marble is provided on the mounting hole of the positioning sleeve via a spring, and a positioning groove cooperating with the marble is provided on the cup mouth mold.

[0009] According to a further solution of the present invention, a silicone sleeve is provided on the protective cover, and an elastic buffer layer is provided on the upper part of the silicone sleeve to buffer the cup mouth mold.

[0010] After adopting the above structure, compared with the prior art, it has the following advantages and effects: First, because the cup mouth mold is detachably locked in the positioning sleeve through marbles, the cup mouth mold is easy and convenient to replace, and the replacement speed is fast and efficient. Second, because the cup is fixed by the arc spring sheet, the cup body is easy and convenient to install online. It can be smoothly installed on the cup mouth mold with just a slight press. The locking is firm and reliable. The container will not fall out during rotary spraying, which can further ensure the stable operation of the assembly line. Third, the cup body clamp realizes automatic disengagement of the cup body through the cooperation of the disengagement washer and the disengagement inclined guide rail. The arc buffer spring sheet and the disengagement washer can play a buffering role in the process of automatic disengagement of the cup body, preventing the cup body from bouncing off the cup mouth mold. Fourth, the cup body can be automatically operated on and off the line, further reducing the number of online employees and greatly saving labor costs. Fifth, the cup mouth mold is easy to replace. Since it is made of high-temperature resistant nylon material, the surface paint is very easy to remove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] Figures 1 to 5As shown, the present invention creates a specific implementation scheme of an automatic release device for a cup spraying assembly line, which includes a guide rail seat 2, an assembly line guide rail 1 rotating around the guide rail seat 2, and a cup body clamp 3 fixed to the assembly line guide rail 1. An automatic release seat 5 is fixed to the guide rail seat 2, and a release inclined guide rail 6 is provided on the automatic release seat 5. An arc-shaped buffer spring sheet 7 is provided on the automatic release seat 5 above the release inclined guide rail 6; the cup body clamp 3 includes an arc-shaped spring sheet 22, a cup mouth mold 20, a positioning sleeve 16, a shield 17, a spring sleeve 13, and a central shaft 8. The cup mouth mold 20 is provided with a connecting socket matching the cup body 4, and the cup mouth mold 20 is detachably locked on the positioning sleeve 16. The upper part of the central shaft 8 is provided with at least three axially distributed spring sheet positioning grooves 10, a plurality of circumferentially distributed positioning tooth slots 9 and a guide groove 26. The arc-shaped spring sheet 22 is correspondingly installed on the spring sleeve 13. On the spring leaf positioning groove 10, a positioning tooth 21 that cooperates with the positioning tooth groove 9 is provided on the arc spring leaf 22, and a guide groove that cooperates with the arc buffer spring leaf 7 and a guide rail that ensures the axial movement of the positioning sleeve 16 are correspondingly provided on the positioning sleeve 16. The positioning sleeve 16 can be axially slidably sleeved on the central shaft 8 and wrap the arc spring leaf 22 through the guide rail and the guide groove 26. The upper and lower parts of the arc spring leaf 22 extend out of the positioning sleeve 16 accordingly, and a fixing sheet 14 is fixed on the shield 17. The spring sleeve 13 is fixed on the fixing sheet 14 and is connected to the positioning sleeve 16 through the shield 17. A release spring 11 is provided between the spring sleeve 13 and the central shaft 8, and a release washer 12 that cooperates with the release inclined guide rail 6 is fixed on the spring sleeve 13. When the positioning sleeve 16 moves up and down, the arc spring leaf 22 is positioned on the central shaft 8 through the positioning tooth 21 and the corresponding positioning tooth groove 9.

[0018] In order to ensure that the cup body 4 is automatically tensioned when installed and automatically released when removed, the cup body clamp 3 enters the automatic release seat 5, such as Figure 3 As shown, the friction resistance between the arc spring piece 22 and the cup body 4 is greater than the elastic force of the trip spring 11; when the trip washer 12 moves along the trip inclined guide rail 6, the trip washer 12 drives the positioning sleeve 16 to move upward along the central axis 8 and the arc spring piece 22 through the spring sleeve 13 and the shield 17, and the friction resistance between the arc spring piece 22 and the cup body 4 gradually decreases; when the elastic force of the trip spring 11 is greater than the friction resistance between the arc spring piece 22 and the cup body 4, as shown in FIG. Figure 4 As shown, the release spring 11 drives the positioning sleeve 16 and the cup mouth mold 20 to bounce upward along the central axis 8 and the arc-shaped spring piece 22 through the spring sleeve 13 and the shield 17, and the positioning sleeve 16 causes the head of the arc-shaped spring piece 22 to retract and release the lock on the cup body 4, as shown in FIG. Figure 5As shown; during the upward bouncing process, the release washer 12 contacts the arc-shaped buffer spring sheet 7 and plays a buffering role, preventing the cup body 4 from falling off the cup mouth mold 20. Due to the arc-shaped spring sheet 22, each cup body clamp 3 can be continuously buffered during the automatic release process of the assembly line, and there will be no greater resistance when the next cup body clamp 3 enters the automatic release device at the same time.

[0019] In order to prevent the arc-shaped spring piece 22 from damaging the inner liner of the cup body 4 and increasing the friction with the cup body 4, a silicone head 23 is fixed to the head of the arc-shaped spring piece 22; in order to ensure reliable conductivity of the cup body and ensure the quality of electrostatic spraying, at least one of the arc-shaped spring pieces 22 has an elastic conductive contact 24 fixed on the head to elastically contact with the cup body 4 to ensure reliable conductivity.

[0020] In order to ensure the easy installation of the release spring 11, an inner positioning piece 28 is fixed in the spring sleeve 13, and an outer positioning piece 27 is provided on the central shaft 8. The release spring 11 is sleeved on the central shaft 8 and arranged between the inner positioning piece 28 and the outer positioning piece 27; in order to control the movement stroke, an upper limit clamp 15 for controlling the stroke of the positioning sleeve 16 and the protective cover 17 is fixed on the central shaft 8.

[0021] In order to facilitate the replacement of the cup mouth mold 20, a marble 25 is provided on the mounting hole of the positioning sleeve 16 through a spring, and a positioning groove is provided on the cup mouth mold 20 to cooperate with the marble 25. The cup mouth mold 20 is made of high temperature resistant nylon material, which is not only high temperature resistant and corrosion resistant, but also has a long service life, and the paint on the surface is very easy to remove.

[0022] In order to ensure that the paint is reduced from sticking to the shield 17 during spraying, a silicone sleeve 18 is provided on the shield 17; in order to reduce the rebound force when the cup body 4 is installed on the cup mouth mold 20, an elastic buffer layer 19 is provided on the upper part of the silicone sleeve 18 to buffer the cup mouth mold 20, thereby ensuring that the cup body 4 and the cup mouth mold 20 are tightly closed and not offset.

[0023] When the spraying assembly line created by the present invention is working, the cup body 4 to be sprayed is first installed before spraying. The cup body 4 covers the upper part of the arc-shaped spring sheet 22 and is pressed down with force to align with the cup mouth mold 20. After the cup body 4 overcomes the elastic force of the release spring 11 through the cup mouth mold 20, it pushes the positioning sleeve 16, the protective cover 3 and the spring sleeve 13 to move downward, and the upper part of the arc-shaped spring sheet 22 gradually opens. When the silicone head 23 and the elastic conductive contact 24 on the upper part of the arc-shaped spring sheet 22 are close to the inner wall of the cup body 4, the arc-shaped spring sheet 22 is elastically deformed, and the elastic resistance continues to increase. When the friction resistance on the upper part of the arc-shaped spring sheet 22 is greater than the elastic force of the release spring 11, the spring sheet positioning groove 10 and the positioning tooth slot 9 lock the arc-shaped spring sheet 22, and the cup mouth of the cup body 4 is close to the cup mouth mold 20, and the inner wall is elastically supported and locked by the arc-shaped spring sheet 22, thereby ensuring that the cup body 4 cannot move up, down, left and right.

[0024] When the cup body clamp 3 drives the cup body 4 into the automatic trip seat 5 after the spraying work is completed, the trip washer 12 gradually moves along the upward inclined trip inclined guide rail 6, and the trip washer 12 drives the positioning sleeve 16 to move upward along the central axis 8 and the arc-shaped spring piece 22 through the spring sleeve 13 and the shield 17, and the friction resistance between the arc-shaped spring piece 22 and the cup body 4 gradually decreases; when the elastic force of the trip spring 11 is greater than the friction resistance between the arc-shaped spring piece 22 and the cup body 4, the trip spring 11 drives the positioning sleeve 16 through the spring sleeve 13 and the shield 17. The positioning sleeve 16 and the cup mouth mold 20 bounce upward along the central axis 8 and the arc-shaped spring sheet 22, and the positioning sleeve 16 causes the head of the arc-shaped spring sheet 22 to retract and release the lock on the cup body 4; during the upward bouncing process, the release washer 12 contacts the arc-shaped buffer spring sheet 7, which can play a buffering role during the bouncing process, preventing the cup body 4 from falling off the cup mouth mold 20, thereby releasing the lock of the arc-shaped spring sheet 22 on the cup body, and the sprayed cup body 4 can be easily removed from the cup body clamp 3, thereby completing the spraying work of the cup body 4.

[0025] The above is only an embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention shall fall within the protection scope of the present invention.
