Description

Technical Field

[0001] The utility model belongs to the field of strip bag filling and sealing machines, in particular to an anti-overflow strip bag filling and sealing machine for paste prescriptions. Background Art

[0002] A strip bag is a strip-shaped plastic bag with a filling port at one end. The paste is injected into the strip bag and sealed through a filling and sealing machine. The open end of the bag shrinks inward to form a neck that makes it easy for diners to suck the paste out of the strip bag. Tear openings are provided on both sides of the neck.

[0003] The structure of the existing filling and sealing machine includes a feeding mechanism, a material taking mechanism, a filling mechanism and a sealing mechanism. Figure 3 As shown, the feeding mechanism includes a frame plate with a through hole, and a plurality of strip bags are stacked on the frame plate. Corresponding to the top of the through hole, a plurality of limit columns distributed around the strip bags are provided on the frame plate. The vacuum suction head on the feeding mechanism takes the material from bottom to top, sucks away the strip bags at the bottom, sends the sucked strip bags to the filling mechanism to be injected with the paste formula, and then to the sealing mechanism for sealing.

[0004] In actual use, it was found that due to the soft material of the strip bag, it is easy to warp during transportation and storage, and usually the whole stack is bent together. From a top-down perspective, the outline of the strip bag actually becomes smaller. After being placed on the feeding mechanism, a gap is formed between the limit column and the strip bag. The limit column cannot limit the horizontal position of the strip bag on the frame. The position of the strip bag is not fixed, and it is easy to rotate at a certain angle horizontally. After being sucked up by the vacuum suction head, the position on the feeding mechanism also rotates to a certain extent. Although it does not affect the subsequent filling, when sealing, due to the strip bag, the position of the sealing line on the strip bag changes accordingly, causing part of the paste to be squeezed out.

[0005] like Figure 4 As shown in the figure, when the strip bag is placed accurately on the frame plate without rotation, the sealing line passes vertically through the neck and no paste will be squeezed out. Figure 5 As shown, when the strip bag is not placed accurately on the frame plate and rotates, the sealing line passes through the neck at an angle, and the paste may be squeezed out.

[0006] Therefore, the existing filling and sealing machine has the defect that the paste formula is easily squeezed out. Utility Model Content

[0007] The utility model aims to provide a filling and sealing machine for paste prescription strip bags that prevent overflow.

[0008] The utility model has the advantage of preventing the ointment prescription from overflowing.

[0009] The technical solution of the utility model is: a filling and sealing machine for paste prescription anti-overflow strip bags, including a feeding mechanism, a material taking mechanism, a filling mechanism and a sealing mechanism. The feeding mechanism includes a frame plate, the frame plate is provided with a through hole matching the outer contour of the strip bag, the frame plate is provided with a plurality of limit columns distributed along the outer side of the through hole, and an annular pressing frame is provided above the through hole, and the shape of the pressing frame matches the outer contour of the strip bag.

[0010] In the aforementioned paste prescription anti-overflow strip bag filling and sealing machine, the inner and outer edges of the bottom of the pressing frame are both provided with a first rounded corner

[0011] In the aforementioned paste prescription overflow-proof strip bag filling and sealing machine, the pressing frame is slidably connected to the limiting column.

[0012] In the aforementioned anti-overflow paste bag filling and sealing machine, the pressing frame is slidably connected to the limiting column via a guide ring, and the guide ring and the limiting column are clearance-matched.

[0013] In the aforementioned anti-overflow strip bag filling and sealing machine for paste prescriptions, two bending plates are provided on the frame plate, and the two bending plates are respectively located on both sides of the neck of the strip bag.

[0014] In the aforementioned paste prescription overflow prevention strip bag filling and sealing machine, the limiting column is cylindrical.

[0015] In the aforementioned paste prescription overflow-proof strip bag filling and sealing machine, a retaining frame is provided above the frame plate, and the upper end of the limiting column is contracted inwardly to form a stepped shaft, and the stepped shaft is inserted into the retaining frame.

[0016] Compared with the prior art, the utility model improves the feeding mechanism on the basis of the existing bag filling and sealing machine. The main improvements are as follows:

[0017] 1) A pressing frame is set above the frame. After the whole stack of strip bags is placed on the frame, the strip bags are flattened by the pressing frame to prevent the strip bags from warping. There is no gap between the strip bags and the limiting columns. The position of the strip bags on the frame is fixed without horizontal rotation, which prevents the paste from overflowing during the subsequent sealing operation.

[0018] 2) Two bending plates are added to the frame plate. The bending plates correspond to the neck and shoulder positions of the strip bag to better prevent the strip bag from rotating on the frame plate.

[0019] 3) A retaining frame is set above the pressing frame, through which the upper ends of each limiting column are fixed. On the basis of using longer limiting columns and being able to put more strip bags at a time, the parallelism between the limiting columns is ensured, and the pressing frame can fall freely to keep the strip bags flat.

[0020] In summary, the utility model has the advantage of preventing the ointment prescription from overflowing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0028] Embodiment 1. A paste prescription anti-overflow strip bag filling and sealing machine is improved on the basis of the purchased XBG50 filling and sealing machine. The structure of the XBG50 filling and sealing machine includes a feeding mechanism, a material taking mechanism, a filling mechanism and a sealing mechanism. The feeding mechanism includes a suspended frame plate 1, and the frame plate 1 is provided with a through hole 2 matching the outer contour of the strip bag. When viewed from above, the through hole 2 is within the outer contour of the strip bag. The frame plate 1 is provided with a plurality of cylindrical limiting columns 3 distributed along the outer side of the through hole 2. The improvement is as follows: Figure 1 As shown,

[0029] An annular pressing frame 4 is provided above the through hole 2. The pressing frame 4 is made of stainless steel, and its shape matches the outer contour of the strip bag. Looking from the top, the outer contour of the pressing frame 4 is the same as the outer contour of the strip bag 10 in the flattened state, and the inner hole contour of the pressing frame 4 is the same as the contour of the through hole 2. The width of the pressing frame 4 is about 4 mm, that is, when the strip bag 10 is placed on the frame plate 1, the outer edge of the strip bag 10 is about 4 mm wide and in contact with the frame plate 1.

[0030] The inner and outer edges of the bottom of the pressing frame 4 are both provided with first rounded corners 5 to prevent the pressing frame 4 from scratching the strip bags 10 in contact with the pressing frame 4 .

[0031] The pressing frame 4 is slidably connected to the limiting column 3 via the guide ring 7, and the guide ring 7 and the limiting column 3 are clearance-matched, with a clearance of about 0.5 mm, so that the pressing frame 4 can be smoothly lifted and lowered.

[0032] The frame plate 1 is provided with two bending plates 6, which are respectively located on both sides of the neck of the bag 10, and the two bending parts of the bending plates 6 are in close contact with the bag 10. The bending plates 6 increase the contact surface between the feeding mechanism and the bag 10, so as to better prevent the bag 10 from deflecting horizontally.

[0033] The method of using the feeding mechanism is as follows: take out the pressing frame 4 upwards, put the whole stack of strip bags 10 on the frame plate 1, limit the position of the strip bags 10 on the frame plate 1 by the bending plate 6 and the limiting column 3, then put the pressing frame 4 back, the pressing frame 4 flattens the strip bags 10, and the strip bags are taken away one by one through the through hole 2.

[0034] Embodiment 2. Based on embodiment 1, a retainer 8 is provided above the frame plate 1, and the upper end of the limit column 3 is contracted inward to form a step shaft 9, the upper end of the step shaft 9 is chamfered, and the step shaft 9 is inserted into the retainer 8. The retainer 8 can be taken out upward.

[0035] Compared with Example 1, when the number of strip bags 10 placed at one time is relatively large, the limiting posts 3 need to be set longer, but this is not conducive to maintaining the parallelism between the limiting posts 3, and may cause the pressing frame 4 to be difficult to fall freely under the action of gravity. Therefore, the upper ends of the limiting posts 3 are restricted by the retaining frame 8, so that the limiting posts 3 remain parallel to each other, ensuring that the pressing frame 4 can fall freely. In Example 1, the length of the limiting posts 3 should not exceed 10 cm, and in Example 2, the length of the limiting posts 3 can be 20 cm.

[0036] The utility model is based on the existing XBG50 filling and sealing machine, and proposes an improved technical solution according to the problems encountered in actual use. The results have been transformed and put into actual production in the workshop. Physical pictures can be provided. Although there are relatively few improvements, relatively obvious technical effects have been achieved and it has good practicality.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
