[0001] This utility model belongs to the field of glass machinery technology, specifically relating to a push rod and a push assembly for a bottle pusher. Background Technology

[0002] Bottle pushers are key pieces of equipment in the glass bottle production process. Glass bottles need to be moved to conveyor equipment on other devices, which requires the use of bottle pushers. For example, Chinese utility model patent application number CN202022756853.1 describes a push rod fixedly installed on the front side of the lifting arm assembly, which pushes a row of bottles. However, due to different production needs, the length of the push rod is also different. Therefore, push rods of various lengths need to be produced according to different production needs. Processing push rods according to production needs will prolong the production cycle and reduce the overall production efficiency. Moreover, some lengths of push rods are used less often, resulting in resource waste. If the push rod is set in segments, the push rod will undergo a large amount of deformation before and after heating, making it impossible for the push rod to remain straight and affecting its use.

[0029] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-9 The present invention will be further described below.

[0030] Example 1

[0031] like Figure 1 As shown, the push rod of this utility model for a bottle pusher includes at least two separate push rod segments, which are sequentially connected to form the entire push rod 1. Each of the two connected push rod segments has a positioning connection part at its connecting end. The two positioning connection parts are correspondingly arranged, and the positioning connection parts of two adjacent push rod segments are connected by a vertically arranged pin 4, allowing for a certain rotational space between the two adjacent push rod segments. The pin 4 is fixed by a locking and fixing assembly. A connecting frame is fixedly installed on the upper side of the connection point of each adjacent push rod segment. The two ends of the connecting frame are respectively fixedly connected to the upper side of the two adjacent push rod segments to further ensure the connection stability of the two push rod segments. The connecting frame includes a mounting bracket 5 and a fixing bracket 11. The mounting bracket 5 is fixedly installed on the upper side of the middle position of the entire push rod 1, and the push rod 1 is fixed to the front end of the bottle pusher by the mounting bracket 5. A mounting bracket 5 or a fixing bracket 11 is fixedly installed on the upper side of the connection point of each pair of adjacent push rod segments, and the two ends of the mounting bracket 5 or the fixing bracket 11 are respectively fixedly connected to the upper side of the two adjacent push rod segments.

[0032] The push rod section includes an end push rod 3 and a middle push rod 12. The end push rod 3 has a positioning connection at only one end, while the middle push rod 12 has positioning connections at both ends. An end bracket 9 is provided at the other end of the end push rod 3. The end bracket 9 is fixedly connected to the end push rod 3 by a connecting bolt 6. A disc spring 7 is provided between the connecting bolt 6 and the end bracket 9. The disc spring 7 has a longer service life than the spring washer. The spring washer will lose its function in a high-temperature environment after being locked and flattened, leading to bolt loosening. The disc spring 7 can greatly reduce the possibility of bolt loosening.

[0033] In this embodiment, the push rod 1 includes two connected end push rods 3. The positioning connection parts of the two end push rods 3 are connected. A mounting bracket 5 is fixedly installed on the upper side of the middle of the two push rods 1. The mounting bracket 5 is connected to both end push rods 3. Several connecting holes 8 are fixedly opened on the upper side of the end push rods 3. The connecting holes 8 are bolt holes. Several through holes are opened on the mounting bracket 5. Each through hole is respectively set with a corresponding connection hole 8. The connecting bolt 6 passes through the through hole of the mounting bracket 5 and is connected to the connecting hole 8. The mounting bracket 5 is fixedly installed on the upper side of the two end push rods 3. A disc spring 7 is provided between the connecting bolt 6 and the mounting bracket 5.

[0034] like Figures 2-3 As shown, the positioning connection parts of the two end push rods 3 are respectively the first positioning connection part and the second positioning connection part. The first positioning connection part and the second positioning connection part are configured to cooperate. The first positioning connection part includes a first connection part 13 and a positioning block 16. The positioning block 16 protrudes from the first connection part 13. The second positioning connection part includes a second connection part 26 and a positioning port 17. The positioning port 17 is opened on the second connection part 26. The positioning block 16 and the positioning port 17 are configured to cooperate. The first connection part 13 and the second connection part 26 are stacked. The first connection part 13 and the second connection part 26 are coaxially provided with corresponding pin holes 14. The pin 4 passes through the two pin holes 14 to connect the two connection parts. The positioning block 16 is configured in the positioning port 17. At the same time, a positioning plate 18 is provided at the end of either end push rod 3. The positioning plate 18 is locked at the end of the connection part of the other end push rod 3 to restrict the movement of the two end push rods 3.

[0035] The locking and fixing assembly includes a connecting groove 15 and a locking bolt 27 on one side of the pin hole 14. A connecting groove 15 is formed along the axial direction of the pin hole 14 on one side, connecting to the pin hole 14. Fixing holes are formed radially along the pin hole 14 on the first connecting part 13 and the second connecting part 26, passing through the connecting groove 15. One side of the fixing hole on either side of the connecting groove 15 is a threaded hole. The connecting bolt 6 passes through the connecting groove 15 from one side of the fixing hole and is threaded onto the other side of the connecting groove 15. Rotating the locking bolt 27 compresses the connecting groove 15, fixing the pin 4 within the pin hole 14. Locking bolts 27 are provided on both the first connecting part 13 and the second connecting part 26. A disc spring 7 is also provided between the locking bolt 27 and the first connecting part 13 and the second connecting part 26. Both the push rod section and the pin 4 are made of cast iron, which greatly reduces the deformation of the push rod 1 caused by uneven heating and the different expansion coefficients due to different materials.

[0036] The push rod 1 in this utility model includes at least two push rod segments, which are connected sequentially. During use, the appropriate number of push rod segments can be selected and connected according to the actual situation, thereby adjusting the length of the push rod 1 and improving production efficiency. Adjacent push rod segments are connected by a first positioning connection part and a second positioning connection part, which are connected by a pin 4. A connecting bolt 6 is provided on one side of the pin 4 to fix it. Before fixing the pin 4, the push rod segments are rotated to keep the push rod 1 straight. After adjusting to be straight, the pin 4 is locked and fixed by the connecting bolt 6. There is a certain rotation space between each push rod segment. By rotating each push rod segment, the deformation of the push rod 1 caused by heat can be compensated.

[0037] Example 2

[0038] like Figure 4 As shown, this embodiment differs from Embodiment 1 in that a middle push rod 12 is connected between the two end push rods 3. The positioning connection parts at both ends of the middle push rod 12 are respectively connected to the positioning connection parts of the two end push rods 3. At this time, the middle part of the entire push rod 1 is the middle push rod 12. Therefore, the mounting bracket 5 is fixedly set on the upper side of the middle push rod 12. The mounting bracket 5 cannot cover the connection between the middle push rod 12 and the end push rods 3. In order to make the connection between the middle push rod 12 and the end push rods 3 stable, the middle push rod 12 and the end push rods 3 are connected by a middle push rod 12. A fixing bracket 11 is connected to the upper side of 3. The connection method of the fixing bracket 11 is the same as that of the mounting bracket 5. It is also fixed on the upper side of the middle push rod 12 and the end push rod 3 by connecting bolts 6. In this embodiment, one end of the fixing bracket 11 is fixedly connected to the end push rod 3, and the other end is fixedly connected to the mounting bracket 5 by connecting bolts 6. A fixing bracket 11 is set at each end of the mounting bracket 5. The fixing bracket 11 covers the connection between the two end push rods 3 and the middle push rod 12 to ensure that the connection between the middle push rod 12 and the end push rod 3 is stable.

[0039] In other embodiments where there is an odd number of middle push rods 12, each middle push rod 12 is connected end to end in sequence. The middle push rods 12 at both ends are connected to the two end push rods 3. A mounting bracket 5 is provided on the upper side of the middle push rod 12 in the middle. The two ends of the mounting bracket 5 are connected to the fixing brackets 11. The fixing brackets 11 cover the upper side of the connection between the middle push rod 12 and the middle push rods 12 at both ends. Fixing brackets 11 are also provided on the upper side of the connection between the other adjacent middle push rods 12 or the connection between the middle push rod 12 and the end push rods 3.

[0040] Example 3

[0041] like Figure 5As shown, this embodiment differs from Embodiment 1 in that two middle push rods 12 are connected between the two end push rods 3. The two middle push rods 12 are connected by a positioning connection part, and the two middle push rods 12 are respectively connected to the positioning connection parts of the two end push rods 3. At this time, the middle part of the entire push rod 1 is the connection point of the two middle push rods 12. Therefore, the mounting bracket 5 is fixedly set on the upper side of the connection point of the two middle push rods 12. A fixing bracket 11 is set on the upper side of the connection point between the middle push rod 12 and the end push rod 3 to ensure that the upper side of the connection point of each adjacent push rod segment is covered by the mounting bracket 5 or the fixing bracket 11. In other embodiments where there is an even number of middle push rods 12, each middle push rod 12 is connected end to end in sequence. The middle push rods 12 at the two ends are connected to the two end push rods 3. The mounting bracket 5 is set on the upper side of the connection point of the two middle push rods 12 in the middle. Fixing brackets 11 are set on the upper side of the connection points of the remaining adjacent middle push rods 12 or the connection points of the middle push rods 12 and the end push rods 3.

[0042] Example 4

[0043] like Figures 6-7 As shown, a bottle-pushing assembly of a bottle pusher according to this utility model includes a push rod 1 and a push claw assembly 2. The push rod 1 is any of the push rods mentioned above. The push claw assembly 2 is fixedly installed on the front side of the push rod 1. The push claw assembly 2 includes a pressure plate 19 and push claws 20. The pressure plate 19 is fixedly connected to the push rod 1, and therefore the pressure plate 19 is also segmented corresponding to the push rod segment. The pressure plate 19 is also divided into an end pressure plate and a middle pressure plate. Each segment of the pressure plate 19 is respectively set on the front side of each push rod segment. Several push claws 20 are evenly spaced along the length direction of the pressure plate 19 on the front side of the pressure plate 19. The glass bottle is pushed by being stuck between adjacent push claws 20. The push rod 1 includes a horizontal segment and a vertical segment that are perpendicular to each other. The horizontal segment is set on the upper side of the vertical segment. The mounting bracket 5 and the fixing bracket 11 are connected to the upper side of the horizontal segment. The pressure plate 19 is connected to the front side of the vertical segment. Here, the front side refers to the side opposite to the horizontal segment of the push rod 1.

[0044] like Figures 8-9 As shown, an installation groove is provided along the length direction on the front side of the push rod section. The cross-section of the pressure plate 19 is "T" shaped. One end of the pressure plate 19 is inserted into the installation groove. Several installation holes 10 are provided on the push rod section. Threaded holes are provided on the pressure plate 19 corresponding to the installation holes 10. The installation bolts 25 pass through the installation holes 10 and are threaded onto the threaded holes of the pressure plate 19 to fix the pressure plate 19 on the front side of the push rod section. In order to ensure the strength at the installation holes 10 of the push rod section, the side of the installation hole 10 away from the pressure plate 19 is thickened and protrudes from the push rod section.

[0045] Each pusher claw 20 is evenly distributed on the front side of the pressure plate 19. A "T"-shaped groove is formed on each pusher claw 20 corresponding to the pressure plate 19. The pressure plate 19 is engaged within the "T"-shaped groove of the pusher claw 20, allowing each pusher claw 20 to slide along the pressure plate 19. Each pusher claw 20 has a threaded hole, and a fixing bolt 23 or a set screw is threadedly connected to the pusher claw 20. Tightening the fixing bolt 23 or set screw presses the end of the fixing bolt 23 or set screw against the pressure plate 19, thus fixing the pusher claw 20. The spacing between the pusher claws 20 can be adjusted by sliding them to accommodate glass bottles of different diameters or sizes. After adjusting the spacing, the pusher claws 20 are fixed by tightening the fixing bolt 23 or set screw. Each pusher claw 20 is made of cast aluminum to reduce the overall weight of the pusher rod 1.

[0046] A pad 21 is fixedly installed at the upper and lower parts of each pusher 20. The two pads 21 are fixed by a vertically installed fixing pin 22. The pads 21 are in direct contact with the glass bottle and are made of various materials, including carbon fiber, DuPont, metal matrix with stainless steel cloth strip, etc., to meet the needs of different bottle types and customers. The pushers 20 and pads 21 are available in various forms and specifications, including arc type, triangular type and flat type, etc., and each form is available in various sizes to meet the pushing needs of glass bottles of different diameters or sizes. A side pad 24 is fixedly installed at both ends of the pusher 1. The side pads 24 are fixedly installed on the end bracket 9 by connecting bolts 6. The outermost glass bottle is pushed between the side pad 24 and the pad 21 of the outermost pusher 20.

[0047] The push rod 1 and pressure plate 19 of this utility model bottle pusher assembly are both set in corresponding segments. The overall length of the bottle pusher assembly can be determined according to actual needs to meet different production requirements and improve production efficiency. Each push claw 20 is connected to the front side of the pressure plate 19, and the spacing can be adjusted by sliding the push claw 20 to match glass bottles of different diameters or sizes. After adjusting the spacing, the push claw 20 can be fixed.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
