Abstract

A packaging machine's pushing mechanism includes: a pushing main system, a fixing mechanism, a frame, a guide rail mechanism, a flow channel plate, and a transmission mechanism. The pushing main system is connected to the fixing mechanism, which is symmetrically arranged on both sides of the frame. The bottom of the frame has a guide rail mechanism connected to the transmission mechanism, which is in turn connected to the fixing mechanism. The flow channel plate is located at the upper end of the frame, and the pushing main system is positioned above it. The pushing main system includes: a pushing plate, a rotating shaft, a fixing plate, a first connecting block, a first connecting rod, a discharge pushing plate, a fixing shaft, a second connecting block, a fixing block, a second connecting rod, a third connecting block, a spherical bearing, and a cylinder.

The movement trajectory of the discharge pushing plate is changed to a linear up-and-down motion, and a pressure plate is added to prevent the packages from bunching together and becoming too tight, thus reducing the risk of bursting.

Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically to a packaging machine pushing mechanism. Background Technology

[0002] On the one hand, traditional push-pack mechanisms cannot be quickly disassembled. Since there are various specifications of flow channel plates, the flow channel plates need to be replaced when switching specifications, which requires disassembling the push-pack mechanism, which is time-consuming and labor-intensive.

[0003] On the other hand, in traditional pack pushing mechanisms, each group rotates. However, during the last group of packs being pushed, the flow channel barriers between the packs disappear due to their convergence, and the width narrows. If the side adjustment blocks are too wide, the packs will tip over; if they are too narrow, the packs will burst open. Even after fixing a width, due to the multi-row packaging machine, the packs sometimes become over-inflated and larger, causing them to burst at the fixed width. A pressure plate is needed to prevent this, but a rotating pack pushing plate cannot accommodate a pressure plate. Therefore, a new pack pushing mechanism needs to be designed.

[0004] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0025] like Figure 1-4As shown, a packaging machine's pushing mechanism includes: a pushing main system 100, a fixing mechanism 200, a frame 300, a guide rail mechanism 400, a flow channel plate 500, and a transmission mechanism 600. The pushing main system 100 is connected to the fixing mechanism 200, which is symmetrically arranged on both sides of the frame 300.

[0026] The main pusher system 100 includes: a pusher plate 110, a rotating shaft 120, a fixed plate 130, a first connecting block 140, a first connecting rod 150, a discharge pusher plate 160, a fixed shaft 170, a second connecting block 180, a fixed block 190, a second connecting rod 1100, a third connecting block 1110, a spherical bearing 1120, and a cylinder 1130. The pusher plate 110 is connected to the rotating shaft 120. The first connecting block 140 is mounted on the rotating shaft 120. Both sides of the rotating shaft 120 are connected to the fixed plate 130 via bearings. The first connecting block 140 is connected to the first connecting rod 150 via a shaft pin. The discharge pusher plate 160 is connected to the rotating shaft 120 via the first connecting block 140. 160 is connected to the fixed shaft 170 via the second connecting block 180. The two sides of the fixed shaft 170 are connected to the fixed plate 130. One end of the fixed shaft 170 is connected to one end of the second connecting rod 1100 via the fixed block 190. The fixed block 190 is connected to the rotating shaft 120. The two ends of the second connecting rod 1100 are provided with bearings and shaft pins. The other end of the second connecting rod 1100 is connected to one end of the third connecting block 1110. The middle section of the third connecting block 1110 is connected to the rotating shaft 120. The other end of the third connecting block 1110 is connected to one end of the spherical bearing 1120. When in use, the other end of the spherical bearing 1120 is connected to the cylinder 1130. The cylinder 1130 is fixed on the fixed mechanism 200.

[0027] The fixing mechanism 200 includes: a positioning pin 210, an upper mounting plate 220, a lower mounting plate 230, a positioning hole 240, a latch 250, and a transmission plate 260. The positioning pin 210 is located at the top of the lower mounting plate 230. The upper mounting plate 220 is connected to the fixing plate 130. The lower end of the upper mounting plate 220 is provided with a positioning hole 240. The latch 250 is connected to the lower mounting plate 230. The positioning hole 240 is connected to the positioning pin 210. When in use, the latch 250 is connected to the upper mounting plate 220. The bottom end of the lower mounting plate 230 is connected to the transmission plate 260. The transmission plate 260 is connected to the transmission mechanism 600.

[0028] The guide rail mechanism 400 includes a guide rail 410 and a guide rail slider 420. The guide rail 410 is connected to the bottom of the frame 300, and the guide rail slider 420 is disposed on the guide rail 410 and connected to the lower mounting plate 230.

[0029] The transmission mechanism 600 includes: a servo motor 610, a reducer 620, a swing arm 630, a transmission connecting block 640, a forward / reverse thread adjustment rod 650, and a transmission joint bearing 660. The servo motor 610 is connected to the reducer 620, the reducer 620 is connected to the swing arm 630, the swing arm 630 is connected to the transmission connecting block 640 through the bearing, the transmission connecting block 640 is connected to the transmission joint bearing 660 through the forward / reverse thread adjustment rod 650, and the transmission joint bearing 660 is connected to the transmission plate 260 through a pin.

[0030] The operating principle of this invention is as follows: material enters the flow channel plate 500, and is then pushed forward by the pusher plate 110 along the flow channel plate 500, before being neatly arranged and ejected from the outlet of the flow channel plate 500. During this process, the power source is the transmission mechanism 600. The servo motor 610 drives the reducer 620, which, after reaching a preset output, drives the swing arm 630 to rotate. The swing arm 630, through the transmission connecting block 640 and the forward / reverse thread adjusting rod 650, in conjunction with the transmission joint bearing 660, causes the connected transmission plate 260 to move back and forth. The transmission plate 260 then drives the lower mounting plate 230 of the fixing mechanism 200, causing the lower mounting plate 230 to move back and forth along the guide rail 410 via the connected and fixed guide rail slider 420. During this process, the lower mounting plate 230, through the connected upper mounting plate 220, drives the connected pusher body system 100, thus realizing the back and forth movement of the pusher body system 100.

[0031] The power source for the pusher plate comes from cylinder 1130. Cylinder 1130 pushes spherical bearing 1120 through cylinder rod. Spherical bearing 1120 drives one end of third connecting block 1110. At the same time, the middle section of third connecting block 1110 is also connected to rotating shaft 120. Rotating shaft 120 drives pusher plate 110 to fold slightly. This folding can realize material feeding and pushing. The other end of third connecting block 1110 drives second connecting rod 1100. Second connecting rod 1100 drives fixed block 190. The upper end of fixed block 190 drives fixed shaft 170. The lower end of fixed block 190 drives the foremost rotating shaft 120. Fixed shaft 170 and rotating shaft 120 together drive discharge pusher plate 160. Rotating shaft 120 is connected to discharge pusher plate 160 through first connecting block 140. Fixed shaft 170 is connected to discharge pusher plate 160 through second connecting block 180, and then drives discharge pusher plate 160 to move up and down linearly.

[0032] The innovation of this utility model is reflected in the fact that the entire bag pushing mechanism can be quickly disassembled as a whole. The principle is that the main bag pushing system 100 and the frame 300 can be quickly disassembled. They are assembled and connected by the fixing mechanism 200, which is to accurately position them by the positioning pin 210 and then use the buckle 250 to achieve fast and stable fixing.

[0033] On the other hand, since the preceding pusher plates all rotate, when pushing the packages to the next station, the pusher plate 110 rotates backward. Therefore, if the last pusher plate uses the same structure, the packages will burst when they bunch together. Because the pusher plate rotates backward, it cannot add a pressure plate, and rotating it forward will also damage the packages. Therefore, this invention redesigns the last pusher mechanism by adding a discharge pusher plate 160 and its matching drive structure. This allows the pusher plate to move linearly up and down without rotating, thus enabling the discharge pusher plate 160 to add a pressure plate to prevent the packages from bursting due to excessive tightness when they bunch together.

[0034] Compared with traditional technology, the main body of the pusher bag system can be quickly disassembled and assembled through the fixing mechanism and frame, which facilitates maintenance and replacement of the flow channel plate; the movement trajectory of the discharge pusher bag plate is changed to a straight up and down movement, and a pressing bag plate is added to prevent the strips from gathering together and causing the risk of bag bursting due to excessive tightness.

[0035] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
