Description

Technical Field

[0001] This utility model relates to the field of shoulder injection equipment technology, and in particular to a precise filling device for the shoulder injection process. Background Technology

[0002] Currently, toothpaste tubes, cosmetic tubes, medicine tubes, and other products are mostly manufactured using a segmented manufacturing method. First, the tube body is made, then glue is injected into the head of the tube body. After the glue solidifies, the shoulder of the tube body is formed. With the rapid development of automated equipment, automated shoulder injection machines have been widely used in the shoulder injection production of soft tubes such as toothpaste tubes and cosmetic tubes. A shoulder injection machine is used to inject glue into one end of the tube body to form a shoulder. This process is also called tube shoulder injection.

[0003] Traditional precision filling devices for the shoulder injection process generally use a fixed support structure for the positioning and support of the tube. This design limits the ability to adjust the spacing of the support seats. It means that once the device design is completed, the spacing of the support seats is fixed and cannot be flexibly adjusted according to actual needs. Therefore, when dealing with tubes of different diameters and lengths, the traditional fixed support structure is inadequate, which reduces the flexibility of the production line and affects production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the spacing of the tube support base cannot be adjusted in the precise filling device of the shoulder injection process. Therefore, we propose a precise filling device for the shoulder injection process.

[0005] To achieve the above objectives, this application adopts the following technical solution: a precision filling device for the shoulder injection process, comprising a frame, a driving device mounted on one side of the frame, an eccentric wheel mounted on one end of the driving device, multiple start-stop devices provided on one side of the frame, a material seat fixed at the bottom of the start-stop device, a melt adhesive provided at the bottom of the start-stop device, a first support fixed on one side of the bottom of the frame, a main support rod slidably connected inside the first support, a second support fixed at the other end of the main support rod, multiple tubes placed between the first support and the second support, L-shaped plates fixed at both ends of the bottom of the first support, a fixing rod slidably connected inside the L-shaped plate, a square plate fixed at one end of the fixing rod, and multiple fixing holes for use with the fixing rod on the top of the main support rod.

[0006] Preferably, a fixing ring is fixed to the surface of the fixing rod, and a first spring is slidably connected to the surface of the fixing rod. One end of the first spring is fixed to the fixing ring, and the other end of the first spring is fixed to the L-shaped plate.

[0007] Preferably, the L-shaped plate has an internal rotatable connection with a limiting rod, one end of which is fixed to a limiting plate, and one side of the limiting plate abuts against a fixed ring.

[0008] Preferably, the surface of the limiting rod is fixed with two limiting rings, which are located on both sides of the L-shaped plate.

[0009] Preferably, sliders are fixed on both sides of the main support rod, and grooves that cooperate with the sliders are opened on both sides inside the first support. A second spring is fixed inside the first support, and the other end of the second spring is fixed to the main support rod.

[0010] Preferably, an auxiliary support rod is fixed to the side of the second support near the first support, and the surface of the auxiliary support rod is slidably connected to the interior of the first support.

[0011] Preferably, an identification sensor is installed on one side of the material holder.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pulling the square plate, the fixing rod is moved downward, causing the fixing rod to disengage from the inside of the fixing hole, thus releasing the fixation between the main support rod and the first support. At this time, the operator can freely adjust the position of the main support rod, thereby adjusting the distance between the first support and the second support to accommodate pipes of different diameters and lengths. There is no need to replace the entire equipment or components, thus saving time on equipment replacement and debugging, improving the flexibility of the production line, simplifying operation, and increasing production efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a precision filling device for the shoulder injection process, including a frame 1, a drive device 2 installed on one side of the frame 1, an eccentric wheel 3 installed at one end of the drive device 2, multiple start-stop devices 4 arranged on one side of the frame 1, a material seat 5 fixed at the bottom of the start-stop device 4, a melt glue 6 arranged at the bottom of the start-stop device 4, a first support 7 fixed on one side of the bottom of the frame 1, a main support rod 8 slidably connected inside the first support 7, a second support 9 fixed at the other end of the main support rod 8, multiple tubes 10 placed between the first support 7 and the second support 9, and L-shaped plates 11 fixed at both ends of the bottom of the first support 7, the L-shaped plates 11 sliding inside... A fixed rod 12 is connected, and a square plate 13 is fixed to one end of the fixed rod 12. The top of the main support rod 8 has multiple fixing holes 14 that cooperate with the fixed rod 12. By pulling the square plate 13, the fixed rod 12 is moved downward, causing the fixed rod 12 to disengage from the inside of the fixing holes 14, thus releasing the fixation between the main support rod 8 and the first support 7. At this time, the operator can adjust the position of the main support rod 8 at will, thereby adjusting the distance between the first support 7 and the second support 9 to accommodate pipes 10 of different diameters and lengths. There is no need to replace the entire equipment or parts, thus saving the time of equipment replacement and debugging, improving the flexibility of the production line, simplifying operation, and improving production efficiency.

[0022] Reference Figure 5As shown in this embodiment: a fixing ring 15 is fixed to the surface of the fixing rod 12, and a first spring 16 is slidably connected to the surface of the fixing rod 12. One end of the first spring 16 is fixed to the fixing ring 15, and the other end of the first spring 16 is fixed to the L-shaped plate 11. A limiting rod 17 is rotatably connected inside the L-shaped plate 11. A limiting plate 18 is fixed to one end of the limiting rod 17, and one side of the limiting plate 18 abuts against the fixing ring 15. Two limiting rings 19 are fixed to the surface of the limiting rod 17 and are located on both sides of the L-shaped plate 11. When the fixing rod 12 is pulled and needs to return to its original position, the fixing rod 12 is released, causing the first spring 16 to push the fixing ring 15 due to the recovery of its elasticity. At this time, the fixing ring 15 will drive the fixing rod 12 to insert into the fixing hole 14, thereby achieving the desired effect. To reset the fixing rod 12 and facilitate repeated use by the user, the structure of the limiting rod 17, limiting plate 18, and limiting ring 19 allows the length of the main support rod 8 to be adjusted when the fixing rod 12 moves away from the interior of the fixing hole 14. Then, the limiting rod 17 is rotated, causing the limiting plate 18 to block the front of the fixing ring 15. After that, the fixing rod 12 is released, causing the first spring 16 to drive the fixing ring 15 to contact the limiting plate 18. At this time, the limiting plate 18 will limit the fixing ring 15. When the fixing rod 12 needs to be inserted into the interior of the fixing hole 14, the limiting rod 17 is rotated so that the limiting plate 18 no longer blocks the fixing ring 15. Then, the first spring 16 will drive the fixing rod 12 to be inserted into the interior of the fixing hole 14, realizing the quick fixation of the main support rod 8 after adjustment.

[0023] Reference Figure 4 As shown in this embodiment: sliders 20 are fixed on both sides of the main support rod 8, and grooves 21 that cooperate with the sliders 20 are opened on both sides of the inside of the first support 7. A second spring 22 is fixed inside the first support 7, and the other end of the second spring 22 is fixed to the main support rod 8. By setting the structure of sliders 20, grooves 21 and second spring 22, when the operator adjusts the distance between the first support 7 and the second support 9, it can avoid excessive force when pulling the second support 9, which would pull the main support rod 8 out of the inside of the first support 7 and affect the filling effect.

[0024] Reference Figure 4 As shown in this embodiment: an auxiliary support rod 23 is fixed on the side of the second support 9 near the first support 7. The surface of the auxiliary support rod 23 is slidably connected to the interior of the first support 7. By setting the auxiliary support rod 23, the second support 9 can be provided with auxiliary support, thereby improving the stability of the structure.

[0025] Reference Figure 2 As shown in this embodiment, an identification sensor 24 is installed on one side of the material holder 5. By setting the identification sensor 24, the specifications, material and other information of the tube body 10 can be identified to ensure filling accuracy and stability.

[0026] The specific steps for using the precision filling device in the shoulder injection process are as follows:

[0027] 1. When it is necessary to adjust the distance between the first support 7 and the second support 9, the square plate 13 is pulled to move the fixing rod 12 downward, so that the fixing rod 12 is disengaged from the inside of the fixing hole 14, and the fixing between the main support rod 8 and the first support 7 is released. At this time, the operator can adjust the position of the main support rod 8 at will, thereby adjusting the distance between the first support 7 and the second support 9 to adapt to pipes 10 of different diameters and lengths. There is no need to replace the entire equipment or parts, thus saving the time of equipment replacement and debugging, improving the flexibility of the production line, simplifying operation, and improving production efficiency.

[0028] Second, when the fixing rod 12 is pulled and needs to return to its original position, the fixing rod 12 is released, causing the first spring 16 to push the fixing ring 15 due to the recovery of its elasticity. At this time, the fixing ring 15 will drive the fixing rod 12 to insert into the fixing hole 14, thus resetting the fixing rod 12 for easy reuse. Subsequently, through the structure of the limiting rod 17, the limiting plate 18, and the limiting ring 19, when the fixing rod 12 moves away from the fixing hole 14, the length of the main support rod 8 can be adjusted. Then rotate the limiting rod 17 to drive the limiting plate 18 to block the front of the fixed ring 15. Then release the fixing rod 12 so that the first spring 16 drives the fixed ring 15 to contact the limiting plate 18. At this time, the limiting plate 18 will limit the fixed ring 15. When the fixing rod 12 needs to be inserted into the fixing hole 14, rotate the limiting rod 17 so that the limiting plate 18 no longer blocks the fixed ring 15. Then the first spring 16 will drive the fixing rod 12 to be inserted into the fixing hole 14, realizing the quick fixation of the main support rod 8 after adjustment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
