Description

Technical Field

[0001] This utility model relates to the technical field of adhesive support devices, and in particular to a packaging tube for containing paste-like adhesives. Background Technology

[0002] Adhesives are substances with excellent adhesive properties, which connect objects by bonding them together through adhesion and cohesion.

[0003] Paste-like adhesives are contained in cylindrical packaging tubes and then squeezed to flow outwards from the device. However, if the extruded adhesive is not completely used, it cannot be recycled back into the packaging tube, which can easily lead to solidification and waste, thus affecting the efficiency of the device.

[0004] Therefore, we provide a packaging tube for containing a paste-like adhesive. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a packaging tube for containing paste-like adhesives, thereby achieving the effect of automatically recycling excess adhesive.

[0006] In view of this, the present invention provides a packaging tube for containing a paste-like adhesive, including a storage cylinder, a pusher plate and a support plate installed inside the storage cylinder. The pusher plate and the support plate are both tightly connected to the inner wall of the storage cylinder. A movable support groove is provided at the upper end of the pusher plate. A limiting component is inserted into the movable support groove. The upper end of the limiting component is installed at the lower end of the support plate. A return spring is installed on the outside of the limiting component. A central support column is rotatably installed at the upper end of the pusher plate. An insertable support cylinder is rotatably installed at the upper end of the support plate. The central support column is inserted into the insertable support cylinder. A first push plate is installed at the upper end of the central support column. A limiting groove is installed at the upper end of the insertable support cylinder. A second push plate is inserted into the first push plate through a limiting strip. The limiting strip is installed on one side of the first push plate.

[0007] Preferably, the lower half of the limiting component is a limiting plate, and the upper half of the limiting component is a plug-in rod. The size of the limiting plate is smaller than the plug-in joint between the limiting component and the movable support groove.

[0008] Preferably, there are several reset springs, with the upper end of the reset spring installed at the lower end of the support plate and the lower end of the reset spring installed at the upper end of the pusher plate.

[0009] Preferably, the middle part of the second push plate is a hollow structure, and the middle support column is inserted into the second push plate.

[0010] Preferably, a limiting groove is provided on one side of the second push plate, and the limiting strip is inserted into the limiting groove.

[0011] Preferably, an arc-shaped support shell is installed on the rear end surface of the storage tube, and a movable insertion groove and a limiting snap-fit ​​groove are respectively opened on both sides of the upper end of the arc-shaped support shell, and the insertion support tube is slidably installed in the middle of the arc-shaped support shell.

[0012] Preferably, the movable insertion slot is inserted into the first push plate, the limiting locking slot is inserted into the second push plate, and the thickness of the movable insertion slot is greater than the thickness of the first push plate.

[0013] Compared with the prior art, the present invention provides a packaging tube for containing paste-like adhesives, which has the following beneficial effects:

[0014] This invention, based on the limiting connection between the first and second push plates by the limiting strip, allows the second push plate on one side to move simultaneously with the first push plate, thereby driving the central support column and the plug-in support cylinder to move simultaneously. This causes the two support discs and the pusher disc inside the receiving cylinder to move simultaneously, squeezing out the adhesive inside the receiving cylinder. This invention, based on the support disc being in a fixed position, allows the pusher disc to retract following the return spring, pulling the used adhesive in the opposite direction, allowing the adhesive at the outlet of the receiving cylinder to move into the device, achieving the effect of automatic retraction of adhesive after use, effectively preventing waste of adhesive. In this invention, when the return spring is in the stretched state, the limiting disc is located at the upper end of the inner wall of the moving support groove. When the return spring drives the pusher disc to retract, the limiting component itself does not move. The pusher disc drives the moving support groove to move simultaneously, causing the lower surface of the inner wall of the moving support groove to contact the lower surface of the limiting disc, achieving the effect of limiting the movement of the pusher disc.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example 1: A packaging tube for containing a paste-like adhesive, such as Figures 1-4 As shown, the device includes a storage cylinder 1, a pusher plate 2 installed inside the storage cylinder 1, and a support plate 4. Both the pusher plate 2 and the support plate 4 are tightly connected to the inner wall of the storage cylinder 1. The upper end of the pusher plate 2 is provided with a movable support groove 6. A limit component 7 is inserted into the movable support groove 6. The upper end of the limit component 7 is installed at the lower end of the support plate 4. A return spring 8 is installed on the outside of the limit component 7. A central support column 3 is rotatably installed on the upper end of the pusher plate 2. An insertable support cylinder 5 is rotatably installed on the upper end of the support plate 4. The central support column 3 is inserted into the insertable support cylinder 5. A first push plate 9 is installed on the upper end of the central support column 3. A limit groove 12 is installed on the upper end of the insertable support cylinder 5. A second push plate 10 is inserted into the first push plate 9 through a limit strip 11. The limit strip 11 is installed on one side of the first push plate 9.

[0024] When the device is in use, the first push plate 9 is first pushed. Based on the limiting connection between the first push plate 9 and the second push plate 10 by the limiting strip 11, the second push plate 10 on one side can move simultaneously with the first push plate 9, thereby driving the middle support column 3 and the insertion support cylinder 5 to move simultaneously. This causes the two support plates 4 and the push plate 2 inside the receiving cylinder 1 to move simultaneously, squeezing out the adhesive inside the receiving cylinder 1. After the material is used up, the first push plate 9 and the second push plate 10 are limited and fixed, achieving simultaneous limiting of the support plates 4 and the push plate 2. The effect is that, based on the initial state of the return spring 8 between the support plate 4 and the push plate 2 being in a stretched state, after the limit bar 11 is released from the limit of the first push plate 9 and the second push plate 10, under the contraction and reset of the return spring 8, based on the support plate 4 being in a fixed position, the push plate 2 retracts and moves with the return spring 8, pulling the used adhesive material in the opposite direction, so that the adhesive material located at the outlet of the collection cylinder 1 can move into the device, achieving the effect of automatic retraction of the adhesive material after the device is used, effectively preventing waste of adhesive material.

[0025] like Figures 1-4 As shown, the lower half of the limiting component 7 is a limiting plate, and the upper half of the limiting component 7 is a plug-in rod. The size of the limiting plate is smaller than the plug-in joint between the limiting component 7 and the movable support groove 6.

[0026] There are several reset springs 8, with the upper end of the reset spring 8 installed at the lower end of the support plate 4 and the lower end of the reset spring 8 installed at the upper end of the pusher plate 2.

[0027] By setting the limiting plate inside the movable support groove 6 for short-distance sliding, and when the return spring 8 is in the stretched state, the limiting plate is located at the upper end of the inner wall of the movable support groove 6. When the return spring 8 drives the pusher plate 2 to retract and move, the limiting component 7 itself will not move. The pusher plate 2 drives the movable support groove 6 to move at the same time, so that the lower surface of the inner wall of the movable support groove 6 contacts the lower surface of the limiting plate, thereby achieving the effect of limiting the movement of the pusher plate 2, while ensuring the reliability and accuracy of the elastic movement of the return spring 8.

[0028] Example 2: A packaging tube for containing a paste-like adhesive, such as Figures 1-4 As shown, the middle part of the second push plate 10 is a hollow structure, and the middle support column 3 is inserted into the second push plate 10.

[0029] A limiting groove 12 is provided on one side of the second push plate 10, and the limiting strip 11 is inserted into the limiting groove 12.

[0030] Under the connection support of the second push plate 10 to the plug-in support cylinder 5 and the guide support of the second push plate 10 to the middle support column 3, the second push plate 10 is able to move stably to the plug-in support cylinder 5, while improving the accuracy of the movement direction of the middle support column 3. At the same time, under the limiting support of the limiting groove 12, the limiting strip 11 is able to accurately limit the connection between the first push plate 9 and the second push plate 10. Furthermore, by adjusting the limiting block on the outside of the limiting strip 11, the distance between the first push plate 9 and the second push plate 10 can be adjusted, and the distance between the push plate 2 and the support plate 4 inside the device can be adjusted accordingly, ensuring the stability and accuracy of the overall distance when the device is in use.

[0031] like Figures 1-4 As shown, an arc-shaped support shell 13 is installed on the rear end surface of the storage tube 1. The upper two sides of the arc-shaped support shell 13 are respectively provided with a movable insertion groove 14 and a limiting locking groove 15, and the insertion support tube 5 is slidably installed in the middle of the arc-shaped support shell 13.

[0032] The movable insertion slot 14 is inserted into the first push plate 9, and the limiting slot 15 is inserted into the second push plate 10. The thickness of the movable insertion slot 14 is greater than the thickness of the first push plate 9.

[0033] When the device is used for limiting, the first push plate 9 is first rotated into the movable insertion slot 14, and then the second push plate 10 is rotated into the limiting locking slot 15. Based on the limiting locking state of the second push plate 10 by the limiting locking slot 15, the prescribed functions of the insertion support cylinder 5 and the support plate 4 are guaranteed. Based on the insertion limitation of the first push plate 9 by the movable insertion slot 14, and the fact that the first push plate 9 can move a short distance inside the movable insertion slot 14, the stability of the moving distance of the push plate 2 when it is driven to shrink and move is guaranteed, which further improves the stability and accuracy of the device's movement during automatic glue collection.

[0034] Working principle: First, the first push plate 9 is pushed. Based on the limiting strip 11, which limits the connection between the first push plate 9 and the second push plate 10, the second push plate 10 on one side can move simultaneously with the first push plate 9. This drives the central support column 3 and the insert support cylinder 5 to move simultaneously, causing the two support plates 4 and the push plate 2 inside the receiving cylinder 1 to move simultaneously, squeezing out the adhesive inside the receiving cylinder 1. After the material is used up, the first push plate 9 and the second push plate 10 are limited and fixed, achieving simultaneous limiting of the support plates 4 and the push plate 2. The effect is that, based on the initial state of the return spring 8 between the support plate 4 and the push plate 2 being stretched, after the limit bar 11 is released from the limit of the first push plate 9 and the second push plate 10, under the contraction and reset of the return spring 8, based on the support plate 4 being in a fixed position, the push plate 2 retracts and moves with the return spring 8, pulling the used adhesive material in the opposite direction, so that the adhesive material located at the outlet of the collection cylinder 1 can move into the device, achieving the effect of automatic retraction of the adhesive material after the device is used, effectively preventing the waste of adhesive material.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
