Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to a contraction mechanism for a vertical filling machine. Background Art

[0002] The closing mechanism used in vertical filling machines is an automated packaging device that fills a fixed amount of liquid into a packaging bag and seals it. In cosmetic production, the closing mechanism of a vertical filling machine is often used to fill liquid cosmetic products (such as lotions, essences, etc.) into replacement bags; when the cosmetic products in the cosmetic bottle are consumed, consumers can transfer the cosmetic products in the replacement bag to the cosmetic bottle.

[0003] Referring to the Chinese patent with publication number CN209617630U, the filling machine generally includes a frame, a bag clamping and feeding mechanism, a bag opening mechanism, an inflation mechanism (also called an inflation device), a filling mechanism (also called a filling device) and a heat sealing mechanism (also called a heat sealing mechanism device) fixed on the frame. The bag clamping and feeding mechanism clamps the bottom of the packaging bag so that the packaging bag passes through the bag opening mechanism, the inflation mechanism, the filling mechanism and the heat sealing mechanism in sequence. The Chinese patent with publication number CN209617632U discloses "a bag clamping and feeding mechanism of a horizontal bag-feeding liquid filling machine", which specifically discloses a specific implementation structure of a bag clamping and feeding mechanism (bag clamping and feeding mechanism). The bag opening mechanism is used to open the bag opening of the packaging bag; the inflation mechanism inflates air into the packaging bag through the bag opening to make the packaging bag open; the filling mechanism fills the liquid product into the packaging bag; the heat sealing mechanism heat-seals the bag opening of the packaging bag, and the heat sealing mechanism includes two relatively arranged heating bodies. When the packaging bag is conveyed between the two heating bodies, the two heating bodies approach each other to heat seal the packaging bag.

[0004] However, in the actual production process, when the filling mechanism fills the liquid product into the packaging bag, the liquid product exerts lateral pressure on the packaging bag, which makes the bag opening open a large distance. Therefore, the distance between the two heating bodies of the heat sealing mechanism is required to be large. When the two heating bodies are close to each other to heat seal the packaging bag, the heating bodies need to move a large distance, which affects the heat sealing effect of the heat sealing mechanism on the packaging bag.

[0006] The present application provides a converging mechanism for a vertical filling machine, which adopts the following technical solution:

[0007] A converging mechanism for a vertical filling machine, the filling machine comprising a frame, a bag clamping mechanism, a filling mechanism and a heat sealing mechanism fixedly arranged on the frame; the bag clamping mechanism is used to clamp and convey the packaging bag to pass through the filling mechanism and the heat sealing mechanism in sequence;

[0009] By adopting the above technical scheme, the bag clamping mechanism clamps the packaging bag and sequentially passes through the filling mechanism, the contraction mechanism and the heat sealing mechanism; when the filling mechanism fills the liquid product into the packaging bag, the liquid product opens the bag opening of the packaging bag; and when the packaging bag is passed between the two contraction plates, the gradually approaching contraction plates guide the bag surfaces of the packaging bag to approach each other to narrow the bag opening of the packaging bag; thereby reducing the moving distance of the heating body in the heat sealing mechanism, facilitating the heat sealing of the packaging bag by the heat sealing mechanism, and improving the heat sealing effect of the heat sealing mechanism on the packaging bag.

[0011] By adopting the above technical solution, the fixing frame and the frame are fixedly connected by bolts, and the bundling plate and the fixing frame are fixedly connected by bolts; thus, it is convenient for workers to install the bundling mechanism.

[0012] Optionally, a plurality of the mounting holes are provided, and the plurality of the mounting holes are vertically spaced apart.

[0013] By adopting the above technical solution and providing a plurality of mounting holes, the height of the bundling plate can be adjusted vertically to accommodate packaging bags of different heights.

[0015] By adopting the above technical solution and arranging a vertical mounting plate, an avoidance gap is provided between the guide plate and the fixing frame, thereby facilitating the packaging bag to pass through the gathering mechanism.

[0016] Optionally, the guide plate is an arc-shaped plate, and the opening directions of the two guide plates are opposite.

[0017] By adopting the above technical solution, the arc-shaped guide plate is conducive to gradually forcing the bag surfaces of the packaging bag to approach each other, thereby shrinking the bag opening component of the packaging bag and reducing the flow of the liquid product in the packaging bag.

[0018] Optionally, the through hole is a long strip-shaped through hole, and the through hole is vertically arranged.

[0023] By adopting the above technical solution, the two installation grooves are staggered, which can reduce the mutual interference of the installation of the bundling plates on both sides of the third plate, making it easier for workers to install.

[0025] 1. When the packaging bag is placed between two gathering plates, the gradually approaching gathering plates guide the bag surfaces of the packaging bag to approach each other, so as to reduce the bag opening of the packaging bag; thereby reducing the moving distance of the heating body in the heat sealing mechanism, making it easier for the heat sealing mechanism to heat seal the packaging bag, and improving the heat sealing effect of the heat sealing mechanism on the packaging bag;

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a converging mechanism for a vertical filling machine.

[0034] In the prior art, a filling machine generally includes a frame 1, a bag clamping mechanism, a bag opening mechanism, an air filling mechanism, a filling mechanism and a heat sealing mechanism fixed on the frame 1. The bag clamping mechanism is used to clamp the packaging bag 6 and pass through the bag mechanism, the air filling mechanism, the filling mechanism and the heat sealing mechanism in sequence. The bag opening mechanism is used to open the bag opening of the packaging bag 6; the air filling mechanism inflates the packaging bag 6 through the bag opening so that the packaging bag 6 is stretched open; the filling mechanism fills the liquid product into the packaging bag 6; the heat sealing mechanism heat-seals the bag opening of the packaging bag 6, and the heat sealing mechanism includes two heating bodies arranged opposite to each other. When the packaging bag 6 is conveyed between the two heating bodies, the two heating bodies approach each other to heat-seal the packaging bag 6.

[0035] The above-mentioned mechanism of the filling machine is the prior art and does not belong to the invention point of the present application; therefore, the present application does not describe the specific results of the above-mentioned mechanism of the filling machine, nor does it show it in the drawings of the specification.

[0036] However, in the actual production process, after the filling mechanism fills the liquid product into the packaging bag 6, the liquid product exerts lateral pressure on the packaging bag 6, so that the bag opening is opened at a larger distance. Therefore, the distance between the two heating bodies of the heat sealing mechanism is required to be larger. When the two heating bodies are close to each other to heat seal the packaging bag 6, the heating bodies need to move a large distance, thereby affecting the heat sealing effect of the heat sealing mechanism on the packaging bag 6.

[0037] Therefore, the present application sets a converging mechanism between the filling mechanism and the heat sealing mechanism to solve the above technical problems.

[0038] Reference Figures 1 to 3 The constriction mechanism includes a fixing frame 2 and a constriction plate 3. The constriction mechanism is fixed on the frame 1 and is arranged on the moving path of the packaging bag 6. The constriction mechanism is used to constrict the bag opening of the packaging bag 6. One end of the fixing frame 2 is fixedly connected to the frame 1, and the other end of the fixing frame 2 is fixedly connected to the constriction plate 3. Two constriction plates 3 are provided, and a gap is provided between the two constriction plates 3 for the packaging bag 6 to pass through.

[0039] Reference Figure 2 and Figure 3 The fixing frame 2 includes a first plate 21, and a second plate 22 and a third plate 23 fixed on both sides of the first plate 21. The second plate 22 and the third plate 23 are both arranged perpendicular to the first plate 21, and the length direction of the first plate 21 is arranged perpendicular to the moving direction of the packaging bag 6. In this embodiment, the first plate 21, the second plate 22 and the third plate 23 are integrally formed.

[0040] Reference Figure 2 and Figure 3 , the second plate 22 is fixedly connected to the frame 1 by bolts 4. Two bunching plates 3 are arranged on both sides of the third plate 23, and the bunching plates 3 are fixedly connected to the third plate 23 by bolts 4, and the third plate 23 is provided with mounting holes 231 for the bolts 4 to pass through. Along the moving direction of the packaging bag 6, the distance between the two bunching plates 3 decreases, and the bunching plates 3 are used to force the bag surfaces of the packaging bag 6 to approach each other. In this embodiment, the fixing frame 2 is fixedly connected to the frame 1 by bolts 4, and the bunching plates 3 are fixedly connected to the fixing frame 2 by bolts 4; thereby facilitating the staff to install the bunching mechanism.

[0041] Reference Figure 2 and Figure 3The bunching plate 3 includes a mounting plate 31 and a guide plate 32, and the mounting plate 31 and the guide plate 32 are integrally formed. The mounting plate 31 is vertically arranged, and a through hole 311 is provided in the mounting plate 31 for the bolt 4 to pass through; the guide plate 32 is horizontally arranged, and the guide plate 32 is used to abut against the bag surface of the packaging bag 6, and the distance between the two guide plates 32 decreases along the conveying direction of the packaging bag 6. The vertical mounting plate 31 allows an avoidance gap to be provided between the guide plate 32 and the fixing frame 2, so as to facilitate the packaging bag 6 to pass through the bunching mechanism.

[0042] Reference Figure 2 and Figure 3 In this embodiment, the guide plates 32 are arc-shaped plates, and the opening directions of the two guide plates 32 are opposite. The arc-shaped guide plates 32 are conducive to gradually forcing the bag surfaces of the packaging bag 6 to approach each other, thereby shrinking the bag opening component of the packaging bag 6 and reducing the flow of the liquid product in the packaging bag 6. In other embodiments, the guide plates 32 can also be straight plates arranged obliquely.

[0043] Reference Figure 2 and Figure 3 The third plate 23 has mounting grooves 232 on both sides for accommodating the mounting plate 31, and the mounting plate 31 abuts against the side walls of the mounting groove 232. The bottom wall of the mounting groove 232 has a plurality of mounting holes 231 for the bolts 4 to pass through, and the plurality of mounting holes 231 are arranged vertically at intervals.

[0044] Reference Figure 2 and Figure 3 After the bolt 4 is passed through the through hole 311 on the mounting plate 31, the bolt 4 is threadedly connected to the side wall of the mounting hole 231; thereby achieving a fixed connection between the fixing frame 2 and the convergence plate 3; at this time, the mounting plate 31 is set in the mounting groove 232. In this embodiment, a gasket 5 is also provided between the bolt 4 and the mounting plate 31 to improve the fixing effect of the bolt 4 on the mounting plate 31. The side wall of the mounting groove 232 has a limiting effect on the mounting plate 31, which is convenient for the installation of the staff on the one hand; on the other hand, it can improve the stability of the connection between the fixing frame 2 and the convergence plate 3.

[0045] Reference Figure 2 and Figure 3 In this embodiment, the two installation grooves 232 are staggered to reduce the mutual interference of the installation of the bundling plates 3 on both sides of the third plate 23, so as to facilitate the installation of the staff.

[0046] Reference Figure 2 and Figure 3 By providing a plurality of mounting holes 231 , the height of the bundling plate 3 can be adjusted vertically to accommodate packaging bags 6 of different heights.

[0047] Reference Figure 2 and Figure 3Meanwhile, the through hole 311 is a long strip through hole 311, and the through hole 311 is arranged vertically. The through hole 311 on the mounting plate 31 is arranged as a vertical long strip through hole 311, so as to realize the stepless adjustment of the vertical height of the bundling plate 3; so that the bundling mechanism can adapt to packaging bags 6 of different specifications.

[0048] The implementation principle of a convergence mechanism for a vertical filling machine in the embodiment of the present application is as follows:

[0049] Reference Figure 1 The bag clamping mechanism clamps and conveys the packaging bag 6 through the filling mechanism, the contraction mechanism and the heat sealing mechanism in sequence; when the filling mechanism fills the liquid product into the packaging bag 6, the liquid product opens the bag opening of the packaging bag 6. Figure 2 When the packaging bag 6 is inserted between the two bundling plates 3, the gradually approaching bundling plates 3 guide the bag surfaces of the packaging bag 6 to approach each other to narrow the bag opening of the packaging bag 6; thereby reducing the moving distance of the heating body in the heat sealing mechanism, making it easier for the heat sealing mechanism to heat seal the packaging bag 6, and improving the heat sealing effect of the heat sealing mechanism on the packaging bag 6.

[0050] 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.
