Description

Technical Field

[0001] The present application relates to the field of PVC handicraft production, and in particular to a glue stirring device. Background Art

[0002] PVC (Polyvinyl Chloride) handicrafts have the advantages of light weight, corrosion resistance and easy processing. They are widely used in the fields of identification products, promotional materials and decorations. For example, in PVC badges, badges with unique designs and shapes are produced through printing, engraving and three-dimensional molding processes. They are used to display group logos and activity entities, and are also often used as rewards or souvenirs, with a wide audience.

[0003] After the design of the PVC badge is completed, before proceeding to the next production process, different colors of PVC glue need to be mixed according to the design requirements so that it can present different colors to meet the design requirements. Then the glue dripping process is completed through the cooperation of the glue dripping machine and the glue dripping mold to make it present the initial shape of the badge, and then it is baked to fix the shape.

[0004] In the process of mixing glue, it is usually necessary to use a stirring device to stir the glue in the container so that different colors of glue can be completely mixed to reduce the color error of the badge after molding. However, in the existing equipment, the glue needs to be placed in the container and stirred first. After the stirring is completed, the container containing the glue is placed in a vacuum device to extract the bubbles in the glue. Because the glue is relatively thick, the bubbles at the bottom of the container are difficult to extract, so that bubbles still remain in the glue. When the glue is injected into the glue dripping machine, the badge pattern is drawn by the glue dripping machine. After the badge pattern is drawn, it is placed in the baking equipment. During the baking process, the gas in the glue will be released along the glue when it encounters high temperature, so that pores will be generated on the surface of the badge after baking and shaping, which will increase the number of defective badges and need further improvement. Utility Model Content

[0005] In order to reduce the amount of gas in the glue after mixing, the present application provides a glue stirring device.

[0006] The present application provides a glue stirring device adopting the following technical solution:

[0007] A glue stirring device comprises a main barrel, a cover body, a vacuum pump, a stirring device and a controller, wherein the cover body covers the main barrel, an air inlet of the vacuum pump is connected to the main barrel, a hollow area for placing a container is provided from its geometric center to its edge, the vacuum pump is arranged on one side of the main barrel, the stirring device is arranged on the cover body, the stirring device comprises a driving member and a stirring knife, the driving member is arranged on the cover body, the stirring knife faces the main barrel and is rotatably connected with the cover body, the driving member drives the stirring knife to rotate, the controller is electrically connected to the vacuum pump and the driving member, a flange is arranged along the edge of the main barrel, the area enclosed by the flange along the main barrel is adapted to the outer contour of the cover body, a limiting disk is arranged at the bottom of the hollow area, the limiting disk is adapted to the shape of the bottom of the container, at least two groups of electromagnets are arranged on the cover body, the electromagnets are evenly distributed on the cover body, and the electromagnets are electrically connected to the controller.

[0008] By adopting the above technical solution, a container containing glue is placed in the hollow area, and then the cover is closed. The vacuum pump and the driving member are started by the controller. The driving member drives the stirring knife to mix and stir the glue in the container. At the same time, the vacuum pump starts to vacuum the main barrel. When the stirring knife stirs the glue, the bubbles in the glue are affected by the suction of the vacuum machine and escape along the glue. The glue is continuously stirred by the stirring knife, so that the glue is in a moving state, so that the bubbles at the bottom of the container can also be extracted by the vacuum pump, which plays a positive guiding role in reducing the amount of gas in the glue after mixing. At the same time, when the cover body carrying the stirring device is placed on the main barrel, the limit and guiding function in the flange enables the cover body to be placed on the main barrel relatively accurately, which is beneficial to reducing the adjustment time of the cover body in the process of placing it on the main barrel. When the container containing glue is placed in the hollow area, the limit function of the limit plate facilitates the placement of the container in the set position, thereby reducing the probability of the stirring knife causing damage to the container containing glue when the driving member drives the stirring knife to rotate due to inaccurate placement of the container containing glue. When the cover body is closed on the main barrel, the electromagnet is controlled by the controller to work, and the electromagnet is used to attract the cover body and the main barrel, thereby reducing the shaking of the cover body when the driving member drives the stirring knife to rotate. At the same time, compared with the conventional method of connecting the cover body and the main barrel by using a lock, the connection is more stable by attracting the cover body and the main barrel by an electromagnet, and in the process of the driving member driving the stirring knife to rotate, the electromagnet is always in a working state, reducing the probability of shaking of the cover body and the main barrel due to vibration.

[0009] Preferably, the main barrel is provided with a first seal and a first groove in an annular shape along its edge, and the surface covered by the cover body and the main barrel is provided with a second groove and a second seal in an annular shape along its edge; when the cover body is covered on the main barrel, the first seal is embedded in the second groove, and the second seal is embedded in the first groove.

[0010] By adopting the above technical solution, through the cooperation of the first seal and the second groove and the cooperation of the second seal and the first groove, when the cover body is closed on the main barrel, the first seal can be placed in the second groove and the second seal can be placed in the first groove, so the sealing is high and the probability of leakage is reduced.

[0011] Preferably, an observation window is provided on the cover body, and the observation window is transparent.

[0012] By adopting the above technical solution, during the glue stirring process, the operator can observe the stirring situation of the glue in the internal container of the main barrel through the observation window, and it is also convenient to promptly discover abnormal conditions in the main barrel, which plays a positive guiding role in reducing the situation where the driving part drives the stirring blade to rotate too fast, causing glue to splash along the hollow area.

[0013] Preferably, a searchlight ring is provided in an annular shape on the surface of the observation window facing the main barrel, and when the cover body is covered on the main barrel, the searchlight ring faces the main barrel.

[0014] By adopting the above technical solution, the searchlight ring provides lighting for the main barrel, which makes it easier for the operator to observe the inside of the main barrel.

[0015] Preferably, the limiting plate is coated with a shock absorbing plate, and when the container is placed in the limiting plate, the bottom of the container abuts against the upper surface of the shock absorbing plate.

[0016] By adopting the above technical scheme, when the driving member drives the stirring blade to stir the glue in the container, the glue in the container will generate centrifugal force along the rotation direction of the stirring blade, thereby indirectly driving the container to rotate along the limit plate. The shock-absorbing plate can provide the container with a friction force in the opposite direction of its rotation, and the centrifugal force is offset by the friction force, so that the container containing glue can be placed relatively stably in the limit plate. At the same time, the shock-absorbing plate can reduce the shaking of the container containing glue, which plays a positive guiding role in improving the stability of the container when it is placed on the limit plate.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. When the driving member drives the stirring blade to mix and stir the glue in the container, the vacuum machine simultaneously starts to vacuum the air in the main barrel, and continuously extracts the air in the main barrel. During the glue stirring process, the glue is continuously escaping along the glue under the influence of the vacuum machine's suction force. The vacuuming and glue mixing and stirring are performed simultaneously, which plays a positive guiding role in reducing the amount of gas in the glue after mixing;

[0019] 2. The electromagnet is used to attract the cover and the main barrel, which improves the convenience of locking the cover and the main barrel. At the same time, when the driving part drives the stirring blade to mix the glue in the container, the electromagnet is always in working state, which reduces the probability of loosening of the connection between the cover and the main barrel due to vibration;

[0020] 3. The limit plate enables the container containing glue to be placed relatively accurately at the designated position, thereby reducing the probability of the stirring blade damaging the container containing glue when the driving member drives the stirring blade to rotate due to inaccurate container placement.

[0027] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0028] The present application embodiment discloses a glue stirring assembly 4. Figure 1 A glue stirring assembly 4 includes a main barrel 1, a cover body 2, a vacuum pump 3, a stirring assembly 4 and a controller 5. The main barrel 1 is provided with a hollow area 11 for placing a container from its geometric center to its edge. The vacuum pump 3 is arranged on one side of the main barrel 1. The vacuum pump 3 is a device for removing gas or steam in a closed container to create a vacuum environment. It is composed of a vacuum pump, a motor and a pipeline, etc. It is a conventional vacuum pumping component. The free end of the pipeline connected to the air inlet of the vacuum pump 3 is installed on the main barrel 1, and the stirring assembly 4 and the controller 5 are arranged on the cover body 2. At the same time, a handle 23 is installed on the cover body 2. When the cover body 2 is closed on the main barrel 1 by the handle 23, the stirring assembly 4 and the vacuum pump 3 are started by the controller 5 to start stirring the glue in the container placed in the main barrel 1, and the main barrel 1 is vacuumed by the vacuum pump 3, thereby reducing the amount of mixed gas in the glue after the mixing and stirring is completed.

[0029] Reference Figure 1 and Figure 2 The stirring assembly 4 includes a driving member and a stirring blade 42. The driving member is arranged on the cover body 2. The stirring blade 42 faces the main barrel 1 and is rotatably connected to the cover body 2. The driving member drives the stirring blade 42 to rotate, and the driving member is electrically connected to the controller 5.

[0030] Specifically, the driving component can be configured as a driving motor 41, a pneumatic motor and other components that can drive the device to rotate. In order to reduce the overall cost and considering that the speed of the pneumatic motor will be affected by the air pressure when the air pressure is insufficient, a driving motor 41 is used as the driving component in this embodiment. The driving motor 41 is installed on the cover body 2, and the output shaft of the driving motor 41 is coaxially fixed with the rotating shaft of the stirring blade 42.

[0031] Therefore, the stirring blade 42 can fully contact with the glue in the container. When the driving motor 41 is started by the controller 5, the output shaft of the driving motor 41 drives the stirring blade 42 coaxially fixed therewith to rotate, so that the bubbles in the glue in the container escape along the glue, thereby reducing the gas content in the glue.

[0032] Reference Figure 2 and Figure 4 A limiting plate 10 is provided at the bottom of the hollow area 11 . The limiting plate 10 is adapted to the shape of the bottom of the container. A shock absorbing plate 101 is coated inside the limiting plate 10 . When the container is placed in the limiting plate 10 , the bottom of the container abuts against the upper surface of the shock absorbing plate 101 .

[0033] Specifically, the outer contour of the limiting plate 10 is set in a circular ring shape, and the inner diameter of the limiting plate 10 is larger than the diameter of the container for holding glue. At the same time, in order to improve the stability of the limiting plate 10 when installed in the main barrel 1 and to reduce the overall cost, the limiting plate 10 and the bottom of the hollow area 11 of the main barrel 1 are fixed by welding. When the driving motor 41 drives the stirring knife 42 to stir the glue in the container, the limiting effect of the limiting plate 10 greatly reduces the shaking of the container holding glue during the stirring process.

[0034] Furthermore, the shock-absorbing plate 101 can be made of canvas or rubber pad with a certain friction force, and the shock-absorbing plate 101 is attached to the limit plate 10 and the area enclosed by the limit plate 10. When the driving motor 41 drives the stirring blade 42 to stir the glue in the container, the glue in the container will generate centrifugal force along the rotation direction of the stirring blade 42. When the container is subjected to the centrifugal force, the container will rotate along the limit plate 10, and the container containing the glue is at risk of overturning. Therefore, the shock-absorbing plate 101 provides the container with a friction force in the opposite direction of its rotation, and the centrifugal force is offset by the friction force, so that when the stirring blade 42 stirs the glue in the container, the container can still be stably placed in the limit plate 10, which plays a positive guiding role in improving the stability of the container when it is placed on the limit plate 10.

[0035] Reference Figure 2 and Figure 3 The main barrel 1 is provided with a flange 6 along its edge, and the area enclosed by the flange 6 along the main barrel 1 is adapted to the outer contour of the cover body 2. The flange 6 is formed by bending a metal sheet. In the process of the cover body 2 being covered on the main barrel 1, the flange 6 limits and guides the cover body 2 so that the cover body 2 can be accurately covered on the main barrel 1, thereby reducing the adjustment time required for the cover body 2 and the main barrel 1 due to misalignment after the cover body 2 is covered on the main barrel 1.

[0036] Reference Figure 3 The main barrel 1 is provided with a first sealing member 12 and a first groove 13 in an annular shape along its edge, and the surface covered by the cover body 2 and the main barrel 1 is provided with a second groove 21 and a second sealing member 22 in an annular shape along its edge; when the cover body 2 is covered on the main barrel 1, the first sealing member 12 is embedded in the second groove 21, and the second sealing member 22 is embedded in the first groove 13.

[0037] Specifically, the first seal 12 and the second seal 22 are both made of sealing strips and are respectively installed at the edge of the upper surface of the main barrel 1 and the edge of the surface covered by the cover body 2 and the main barrel 1. Therefore, when the cover body 2 is covered on the main barrel 1, the first seal 12 is located in the second groove 21, and the second seal 22 is located in the first groove 13. At this time, the first seal 12 and the second seal 22 are in a cross-staggered arrangement. By cooperating with the second groove 21 and the first groove 13, the sealing of the main barrel 1 is further enhanced after the cover body 2 is covered on the main barrel 1, thereby reducing the amount of air outside the main barrel 1 entering the hollow area 11 during the vacuuming process of the hollow area 11 by the vacuum machine 3, and to a certain extent solves the problem of poor glue bubble removal effect caused by poor sealing between the cover body 2 and the main barrel 1.

[0038] Reference Figure 2 and Figure 5 At least two groups of electromagnets 7 are arranged on the cover body 2 , and the electromagnets 7 are evenly distributed on the cover body 2 , and the electromagnets 7 are electrically connected to the controller 5 .

[0039] Specifically, the electromagnet 7 is a device that uses the principle of generating a magnetic field by passing an electric current through a coil, thereby generating a magnetic attraction or a magnetic repulsion. When the electromagnet 7 is energized, the electromagnet 7 can be attracted to an iron or magnetic object. When the electromagnet 7 is de-energized, the attraction between the electromagnet 7 and the iron or magnetic object disappears. This is a prior art and will not be elaborated on here.

[0040] In this embodiment, two groups of electromagnets 7 are provided, and the two groups of electromagnets 7 are symmetrically installed on the cover body 2 along the geometric center of the cover body 2 toward its edge.

[0041] Therefore, when the cover body 2 carries the driving motor 41 and the stirring blade 42 and covers the main barrel 1, the electromagnet 7 is started by the controller 5 to start working, and the coil in the electromagnet 7 is energized to generate a magnetic field. Since the main barrel 1 and the cover body 2 are made of iron material, when the electromagnet 7 is energized, the cover body 2 and the main barrel 1 can be quickly attracted together. When the driving motor 41 drives the stirring blade 42 to rotate, the cover body 2 is vibrated. Through the magnetic force of the electromagnet 7, the probability of the cover body 2 being loosened due to the vibration of the main barrel 1 is reduced.

[0042] At the same time, when the driving motor 41 and the vacuum pump 3 work normally, the electromagnet 7 is always in a powered state. During this process, the operator cannot open the cover 2, which plays a positive guiding role in improving the overall safety.

[0043] Reference Figure 1 An observation window 8 is provided on the cover body 2, and the observation window 8 is transparent. A searchlight ring 9 is provided in a ring shape on the surface of the observation window 8 facing the main barrel 1. When the cover body 2 is covered on the main barrel 1, the searchlight ring 9 faces the main barrel 1.

[0044] Specifically, the observation window 8 can be made of hard, pressure-resistant and transparent materials such as tempered glass, and the connection between the observation window 8 and the main barrel 1 is sealed, thereby reducing the amount of external gas of the main barrel 1 entering the hollow area 11 along the gap between the observation window 8 and the main barrel 1. The operator can observe the situation of the hollow area 11 of the main barrel 1 through the observation window 8, which is convenient for timely detection and processing of abnormal conditions in the hollow area 11.

[0045] Furthermore, the searchlight ring 9 can be a LED (Light Emitting Diode) light ring, and the searchlight ring 9 is installed on the observation window 8. When the cover body 2 is covered on the main barrel 1, the main barrel 1 is in a closed environment, so that the hollow area 11 is relatively dark. The hollow area 11 is illuminated by the searchlight ring 9, and there is no need to use other lighting tools to illuminate the hollow area 11, which is very convenient.

[0046] The implementation principle of a glue stirring component 4 in an embodiment of the present application is as follows: an operator places a container containing glue in a limiting plate 10, and covers the cover body 2 on the main barrel 1. At this time, the stirring blade 42 is just located in the container, and the driving motor 41 and the vacuum pump 3 are started by the controller 5. At the same time, the coils of the two sets of electromagnets 7 are energized to quickly attract the cover body 2 and the main barrel 1. The driving motor 41 drives the stirring blade 42 to mix and stir the glue in the container, so that the gas in the glue is separated from the glue during the mixing and stirring process. At the same time, the vacuum pump 3 starts to extract the gas in the hollow area 11, and the operator can observe the condition in the hollow area 11 in real time through the observation window 8. The above process greatly reduces the amount of gas in the glue after mixing.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
