Description

Technical Field

[0001] The utility model relates to the field of packaging machinery, in particular to a dust-proof structure of a lifting filling mechanism. Background Technique

[0002] At present, most roll film packaging equipment is composed of a film unwinding device, a folding device, a heat-sealing edge device, a filling device, a heat-sealing mouth device, a cutting device, etc. Among them, the film unwinding device is for placing a roll of strip-shaped packaging film; the packaging film is conveyed horizontally to the folding device; on the folding device, the two side edges of the packaging film are folded upward; the heat-sealing edge device performs heat-sealing in sequence in the length direction of the folded packaging film to form a vertical heat-sealing edge, and a packaging bag with an upper opening is formed between adjacent vertical heat-sealing edges; on the filling device, there is an adsorbing and bag-opening mechanism with opposing rollers, and the adsorbing and bag-opening mechanism has large adsorbing rollers and small adsorbing rollers that roll horizontally in opposition to open the upper bag mouth of the packaging bag through adsorption; on the filling device, there is a blanking mechanism and a lifting filling mechanism. The blanking mechanism is arranged above the large adsorbing roller. The lifting filling mechanism includes a lifting guide cam, a plurality of lifting vertical rods, and a plurality of filling funnels. The lifting guide cam is arranged inside the large adsorbing roller. Each lifting vertical rod can vertically slide through the large adsorbing roller and is in sliding contact with the lifting guide cam. When the large adsorbing roller rotates, each lifting vertical rod rotates with the large adsorbing roller and makes a reciprocating lifting motion under the guidance of the lifting guide cam; each filling funnel is respectively connected to the upper end of each lifting vertical rod passing through the top surface of the large adsorbing roller. In this way, each filling funnel can be driven by the lifting vertical rod to make a lifting motion, so that the lower end of the filling funnel can be inserted into the opened packaging bag and removed from the packaging bag. In this way, filling can be carried out when the filling funnel is inserted into the packaging bag, which can ensure the accuracy of filling; after the filling device completes filling, the heat-sealing mouth device seals the bag mouth of the packaging bag; finally, the cutting device cuts from the middle of the vertical heat-sealing edge, so that an independently packaged product can be obtained.

[0003] Since the upper end of the aforementioned lifting rod can only slide vertically through the large suction roller, and since the filling hopper and the lifting rod are currently mostly connected by a horizontal rod, specifically, the ends of the horizontal rod are respectively connected to the outer wall of the filling hopper and the side wall of the lifting rod. Therefore, it can be seen that there is no shielding structure at the hole on the top of the large suction roller for the upper end of the lifting rod to slide through. Therefore, during use, dust can easily fall directly on the hole on the top of the large suction roller for the upper end of the lifting rod to slide through, which can easily increase the friction resistance of the lifting rod and further cause wear of the lifting rod and the large suction roller. This can easily lead to the gap between the lifting rod and the large suction roller being too large after a period of use, allowing dust to enter the inner side of the large suction roller through this large gap and contact the lifting guide cam, increasing wear of the lifting guide cam, and inaccurate vertical movement of the lifting rod. This is particularly evident when packaging powder products, because the dispersion of powder is difficult to control.

[0004] Therefore, it is very necessary to design a dust-proof structure for the lifting filler mechanism. Utility Model Content

[0005] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings, and to provide a dust-proof structure for a lifting and filling mechanism, which can effectively improve the dust-proof performance of the penetration point of the lifting and filling mechanism, and can greatly reduce the wear caused by dust and powder products, thereby enabling the lifting and filling mechanism to maintain high movement accuracy for a long time, and further can help greatly improve the service life of the lifting and filling mechanism.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A dustproof structure for a lifting filler mechanism is characterized in that it comprises a guide convex tube for a lifting vertical rod to slide through, a dustproof sleeve for sleeve-fitting the upper end of the lifting vertical rod and for installing a filler funnel, and the dustproof sleeve is slidably sleeved on the upper end of the guide convex tube.

[0008] Preferably, the lower end of the guide convex tube is an insertion end.

[0009] Preferably, the outer diameter of the insertion end is smaller than the outer diameter of the upper end of the guide convex tube.

[0010] Preferably, an annular groove is provided on the circumferential surface of the lower end of the insertion end.

[0011] Preferably, the inner hole of the dustproof sleeve is opened vertically, the lower inner hole of the dustproof sleeve is a sliding hole, the upper inner hole of the dustproof sleeve is a fitting hole for fixing the upper end of the lifting vertical rod, and the aperture of the fitting hole is smaller than the aperture of the sliding hole, and the sliding hole can be vertically slidably fitted on the guide convex tube.

[0012] Preferably, threaded holes penetrating through to the sleeving holes are formed in the outer wall of the dust-proof sleeve.

[0013] Preferably, positioning arms are provided on the outer wall of the dust-proof sleeve, and a stuffing funnel is provided at the outer end of the positioning arm.

[0014] Preferably, the upper and lower ports of the stuffing funnel are a round port end and a flat port end respectively.

[0015] Preferably, the dust-proof sleeve, the positioning arm and the stuffing funnel are of an integral structure.

[0016] The beneficial effects of the present utility model: In this dust-proof structure, a guiding convex tube through which the lifting vertical rod slides and penetrates, a dust-proof sleeve for clamping the lifting vertical rod and installing the stuffing funnel are adopted, and the dust-proof sleeve is slidably sleeved on the upper end of the guiding convex tube. This can, without affecting the lifting movement of the lifting vertical rod, effectively shield the penetration part of the lifting vertical rod by the guiding convex tube and the dust-proof sleeve, which can prevent dust from directly falling on the hole through which the lifting vertical rod slides and penetrates. This can help keep the frictional resistance received by the lifting vertical rod within a small range for a long time, thereby helping to greatly reduce the wear speed of the lifting vertical rod and the large adsorption roller. This can, during long-term use, avoid unfavorable situations such as excessive gaps due to wear between the lifting vertical rod and the large adsorption roller, dust entering the large adsorption roller through the gap between the lifting vertical rod and the large adsorption roller and contacting the lifting guiding cam, aggravated wear of the lifting guiding cam, inaccurate vertical movement of the lifting vertical rod, etc. It is very suitable for the environment of packaging powder products. Therefore, this dust-proof structure can effectively improve the dust-proof performance of the penetration part of the lifting stuffing mechanism, which can greatly reduce the wear caused by dust and powder products, thereby helping to keep the lifting stuffing mechanism at a high movement accuracy for a long time, and further helping to greatly improve the service life of the lifting stuffing mechanism.

[0026] As Figures 1 to 3 shown, a dust-proof structure of a lifting packing mechanism according to the present utility model includes a guiding convex tube 1 through which a lifting vertical rod slides and penetrates, and a dust-proof sleeve 2 for sleeving the upper end of the lifting vertical rod and installing a packing funnel. The dust-proof sleeve 2 is slidably sleeved on the upper end of the guiding convex tube 1.

[0027] In this dust-proof structure, a guiding convex tube 1 through which a lifting vertical rod slides and penetrates and a dust-proof sleeve 2 for clamping the lifting vertical rod and installing a packing funnel are adopted, and the dust-proof sleeve 2 is slidably sleeved on the upper end of the guiding convex tube 1. This can, without affecting the lifting movement of the lifting vertical rod, utilize the guiding convex tube 1 and the dust-proof sleeve 2 to effectively shield the penetration part of the lifting vertical rod, which can prevent dust from directly falling on the hole through which the lifting vertical rod slides and penetrates, which is beneficial to keeping the frictional resistance received by the lifting vertical rod within a small range for a long time, thereby being beneficial to greatly reducing the wear speed of the lifting vertical rod and the large adsorption roller. This can, under long-term use, avoid unfavorable situations such as too large a gap between the lifting vertical rod and the large adsorption roller due to wear, dust entering the large adsorption roller through the gap between the lifting vertical rod and the large adsorption roller and contacting the lifting guiding cam, increased wear of the lifting guiding cam, and inaccurate vertical movement of the lifting vertical rod. It is very suitable for the environment of packaging powder products. Therefore, this dust-proof structure can effectively improve the dust-proof performance at the penetration part of the lifting packing mechanism, which can greatly reduce the wear caused by dust and powder products, thereby being beneficial to keeping the lifting packing mechanism at a high movement accuracy for a long time, and further being beneficial to greatly increasing the service life of the lifting packing mechanism.

[0028] As Figures 2 to 4 shown, the lower end of the guiding convex tube 1 is an insertion end 11. This can be inserted and positioned on the large adsorption roller through the insertion end 11, which greatly improves the convenience of installing and positioning the guiding convex tube 1. [[ID=***]]

[0029] As shown in the figure to Figure 4As shown in the figure, the outer diameter of the insertion end 11 is smaller than the outer diameter of the upper end of the guiding convex tube 1. In this way, the guiding convex tube 1 as a whole forms a stepped tube with a larger upper part and a smaller lower part, which can facilitate the quick and accurate positioning of the installation position of the guiding convex tube 1 by the lower end surface of the guiding convex tube 1, thus greatly improving the convenience and accuracy of the installation and positioning of the guiding convex tube 1.

[0030] As Figure 4 shown in the figure, an annular groove 12 is provided on the circumferential surface at the lower end of the insertion end 11. The annular groove 12 can be used for embedding a limiting rubber ring, a snap ring or a limiting block, etc., which can achieve the purpose of stably positioning the guiding convex tube 1 by using the limiting rubber ring, the snap ring or the limiting block, etc., thus facilitating the improvement of the stability of the installation and positioning of the guiding convex tube 1, and further contributing to the improvement of the applicability of the dust-proof structure.

[0031] As Figure 3 shown in the figure, the inner hole of the dust-proof sleeve 2 is vertically penetrated. The lower inner hole of the dust-proof sleeve 2 is a sliding sleeve hole 21, and the upper inner hole of the dust-proof sleeve 2 is a sleeve hole 22 for fixedly sleeving the upper end of the lifting vertical rod, and the aperture of the sleeve hole 22 is smaller than the aperture of the sliding sleeve hole 21. The sliding sleeve hole 21 can be vertically slidably sleeved on the guiding convex tube 1. This can not only stably achieve the dust-proof effect, but also facilitate the manufacturing of the dust-proof sleeve 2, as well as the accurate assembly and sliding, thus contributing to the further improvement of the reliability and applicability of the dust-proof structure.

[0032] As Figure 3 shown in the figure, a threaded hole 23 penetrating through to the sleeve hole 22 is provided on the outer wall of the dust-proof sleeve 2. The threaded hole 23 can be screwed with a set screw (not shown in the figure) or other screws that can achieve pressing and locking. In this way, the dust-proof sleeve 2 can be stably fixed on the lifting vertical rod by using the set screw or other screws that can achieve pressing and locking, which can greatly improve the stability and reliability of the installation and positioning of the dust-proof sleeve 2.

[0033] As Figures 1 to 3 shown in the figure, a positioning arm 3 is provided on the outer wall of the dust-proof sleeve 2, and a stuffing funnel 4 is provided at the outer end of the positioning arm 3. This can form a simple and reliable stuffing structure, thus enabling the dust-proof structure to have high applicability.

[0034] As Figure 1 And Figure 3 shown in the figure, the upper and lower ports of the stuffing funnel 4 are respectively a round mouth end 41 and a flat mouth end 42. This can not only facilitate the stable receiving of materials, but also facilitate the stable stuffing of materials, thus contributing to the improvement of the reliability and applicability of the stuffing funnel 4.

[0035] As Figure 3As shown, the dust-proof sleeve 2, the positioning arm 3 and the stuffing funnel 4 are of an integral structure. By installing and positioning the dust-proof sleeve 2 in this way, the stuffing funnel 4 can be installed in place, which helps to further improve the convenience of assembly.

[0036] As Figures 5 to 9 shown, during actual manufacturing and installation, a number of positioning holes 101 penetrating into its interior are provided on the top surface of the large adsorption roller 10. The insertion end 11 is inserted into the positioning hole 101, and a circlip (not shown in the figure) is clamped on the annular groove 12 and the circlip is pressed against the inner cavity wall of the large adsorption roller 10; the upper end of the lifting vertical rod 20 can vertically slide through the inner hole of the guiding convex tube 1; the sleeve hole 22 is sleeved on the upper end of the lifting vertical rod 20 that passes through the guiding convex tube 1, and the sliding sleeve hole 21 can also vertically slide and be sleeved on the upper end of the guiding convex tube 1; a set screw or other screw that can achieve pressing and locking (not shown in the figure) is screwed into the threaded hole 23, and the set screw or other screw that can achieve pressing and locking is pressed against the upper end of the lifting vertical rod 20. In this way, this dust-proof structure can effectively improve the dust-proof performance at the place where the lifting stuffing mechanism penetrates. It can greatly reduce the wear caused by dust and powder products, so that the lifting stuffing mechanism can maintain a high movement accuracy for a long time, and further greatly improve the service life of the lifting stuffing mechanism.
