[0033] like Figure 1As shown, a straight feed upward pushing mechanism provided by the utility model includes a base 100, a lifting assembly 200 and a translation assembly 300. The base 100 is provided with a conveyor belt 101 for conveying articles; the lifting assembly 200 is arranged on the base 100, and a lifting device support plate 2011 is arranged on the lifting assembly 200, wherein the lifting device support plate 2011 is located at the unloading port of the conveyor belt 101, and the lifting assembly 200 can drive the lifting device support plate 2011 to move up and down at the unloading port of the conveyor belt 101. As the optimal embodiment, the initial position of the lifting device plate 2011 is on the same horizontal plane as the transmission belt 101. Optionally, the lifting device plate 2011 may also be slightly lower than the plane where the conveyor belt 101 is located. The translation assembly 300 is arranged on the base 100, and a push plate 301 is arranged on the translation assembly 300. The push plate 301 performs reciprocating translation motion under the action of the translation assembly 300, so that the push plate 301 pushes the product on the lifting device plate 2011 to the target position. When the product detaches from the conveyor belt 101 and is placed on the lifting device plate 2011, the lifting assembly 300 is lifted. Component 200 drives the lifter pallet 2011 to a preset position, which is the highest point of the lifter pallet, and remains stationary. At the same time, the translation component 300 drives the push plate 301 to translate to one side of the lifter pallet 2011, and completely pushes the product on the lifter pallet 2011 to the next process. The lifter pallet 2011 is driven by the lifting component 200 to return to the unloading port of the conveyor belt 101, and the push plate 301 is also driven by the translation component 300 to return to the left side of the lifter pallet 2011, and then the next product lifting and pushing cycle is carried out.

[0034] In one embodiment, Figure 1 and Figure 4 As shown, the lifting assembly 200 includes a first lifting module 201 composed of a first guide rail 2012 and a first slider 2013.

The first slider 2013 can be slidably set on the first guide rail 2012. The material lifter plate 2011 is fixedly set on the first slider 2013. The first slider 2013 can slide along the first guide rail 2012 to drive the lifting of the material lifter plate 2011. In this embodiment, the movement of the first slider 2013 can be achieved through a screw slider structure or a pneumatic guide rail slider structure or a hydraulic mechanism and other transmission structures. The first slider 2013 can be reciprocated along the first guide rail 2012 by controlling the forward and reverse rotation of the motor or the flow direction of the airflow or hydraulic liquid. It can be understood that the movement mode of the first slider 2013 along the first guide rail 2012 is not limited by the present invention. The main purpose is to drive the lifter plate 2011 to reciprocate and lift through the first slider 2013.

[0035] In one embodiment, again referring to Figure 4 The lifting assembly 200 also includes a cam assembly 202, which includes a first connecting rod 2023, a first swing arm 2021, a power wheel 2022 and a first transmission shaft 103.

The first transmission shaft 103 is arranged on the base 100, and the first transmission shaft 103 can rotate relative to the base 100. The power wheel 2022 is fixedly arranged on the first transmission shaft 103 and can rotate with the first transmission shaft 103. It should be particularly noted that Figure 5 As shown, a cam slot 20221 is provided on the power wheel 2022, and a first roller 20211 adapted to the cam slot 20221 is provided on the first swing arm 2021. The first roller 20211 is provided between the two hinge points of the first swing arm 2021. The first roller 20211 is located on the cam slot 20221 and can slide along the cam slot 20221. Specifically, the first connecting rod 2023 and the first slider 2013 are connected by a hole-shaft connection. In this embodiment, a connecting shaft is provided on the first slider 2013, and an adapted connecting hole is provided at one end of the first connecting rod 2023. Alternatively, a connecting hole is provided on the first slider 2013, and an adapted connecting shaft is provided at one end of the first connecting rod 2023. The connection between the two can also be achieved. In order to realize the hinge connection between the first connecting rod 2023 and the first swing arm 2021, as shown in FIG. Figure 6 As shown, a first hinge hole 20213 is provided at one end of the first swing arm 2021 close to the first connecting rod 2023, and a hinge hole of the same size is provided at one end of the first connecting rod close to the first swing arm 2021, and the two are movably connected via a connecting shaft. Optionally, an integrally provided connecting shaft may be provided on the first swing arm 2021, and movably sleeved in the hinge hole of the first connecting rod 2023 close to the first swing arm 2021, or a first hinge hole 20213 may be provided on the first swing arm 2021, and an integrally provided connecting shaft adapted to the first hinge hole 20213 may be provided on the first connecting rod 2023, and the hinge connection between the first connecting rod 2023 and the first swing arm 2021 may also be achieved.

[0036] In order to realize the hinge connection between the first swing arm 2021 and the base 100, in this embodiment, a second hinge hole 20212 is provided at one end of the first swing arm 2021 away from the first connecting rod 2023, and a first rotating shaft 104 that can rotate relative to the base 100 is provided on the base 100. The first swing arm 2021 is sleeved and fixed on the first rotating shaft 104 through the second hinge hole 20212, and rotates synchronously with the first rotating shaft 104, so as to realize the swing of the first swing arm 2021 close to the first connecting rod 2023. Optionally, the first swing arm 2021 and the first rotating shaft 104 can also be set as an integral structure, or the first rotating shaft 104 is fixedly provided on the base 100, and the first swing arm 2021 is movably sleeved on the first rotating shaft 104 through the second hinge hole 20212.

[0037] Furthermore, in order to realize the rotation of the power wheel 2022 and drive the first swing arm 2021 to swing, the first transmission shaft 103 is rotatably arranged on the base 100 through a bearing structure, and the power wheel 2022 and the first transmission shaft 103 are fixedly connected in the form of a key and a keyway, so that the power wheel 2022 and the first transmission shaft 103 rotate synchronously. Figure 6 As shown, a first roller 20211 is arranged on the first swing arm 2021. The first roller 20211 can be arranged to be a structure integrated with the first swing arm 2021, or the first roller 20211 is rotatably arranged on the first swing arm 2021. When the first roller 20211 is located on the cam slot 20221, the first roller 20211 can rotate along the slot wall of the cam slot 20221 to reduce the friction between the first roller 20211 and the cam slot 20221, and a preset gap is arranged between the first swing arm 2021 and the power wheel 2022, so that the first swing arm 2021 does not contact the power wheel 2022 during the swinging process.

[0038] In one embodiment, Figure 5 As shown, the cam slot 20221 includes a feeding section 202211, an ascending section 202212, a discharging section 202213 and a descending section 202214. The feeding section 202211, the ascending section 202212, the discharging section 202213 and the descending section 202214 are sequentially connected end to end to form a closed annular slot. When the first roller 20211 is located at the feeding section 202211 of the cam slot 20221, as shown in FIG. Figure 3As shown, the feeder support plate 2011 is located at the unloading port of the conveyor belt 101 and remains stationary, that is, the feeding section 202211 is a circular arc section with a smaller radius and a constant radius, and the center of the circular arc of the feeding section 202211 is the rotation center of the power wheel 2022. At this time, the distance between the first roller 20211 and the first transmission shaft 103 remains unchanged, that is, the first swing arm 2021 remains stationary; the rising section 202212 is a straight line slot, which is tangent to the circular arc of the feeding section 202211. When the first roller 20211 is located at the rising section 202212 of the cam slot 20221, the distance between the first roller 20211 and the first transmission shaft 103 gradually increases, thereby The power wheel 2022 drives the first swing arm 2021 to swing away from the first transmission shaft 103, so as to drive the first slider 2013 to move along the first guide rail 2012, and the first slider 2013 drives the lifting device support plate 2011 to be lifted to a preset position; the unloading section 202213, that is, the arc section with a larger radius and a constant radius, is located near the periphery of the power wheel 2022, and the arc center of the unloading section 202213 coincides with the rotation center of the power wheel 2022. When the first roller 20211 is located in the unloading section 202213 of the cam slot 20221, the distance between the first roller 20211 and the first transmission shaft 103 remains unchanged, so that the lifting device support plate 2011 remains stationary. Figure 2As shown, the material lifter pallet 2011 has just entered the unloading section 202213, so that the pushing plate 301 completely pushes the product away from the material lifter pallet 2011; the descending section 202214 is the same as the ascending section 202212, and is also a straight slot, and is tangent to the loading section 202211 of the arc section with a smaller diameter, and the slot of the ascending section 202212 is the same as the slot of the descending section 202214. When the first roller 20211 is located in the descending section 202214 of the cam slot 20221, the distance between the first roller 20211 and the first transmission shaft 103 gradually decreases, and the power wheel 2022 drives the first swing arm 2021 to swing toward the side close to the first transmission shaft 103, so as to drive the first slider 2013 to move along the first guide rail 2012, and the first slider 2013 drives the material lifter pallet 2011 to descend to its initial position. In order to facilitate the first roller 20211 to move smoothly from the ascending section 202212 to the unloading section 202213 and from the unloading section 202213 to the descending section 202214, a circular arc transition connection is adopted between the ascending section 202212 and the unloading section 202213. Similarly, a circular arc transition connection is adopted between the unloading section 202213 and the descending section 202214, thereby ensuring the continuity of the entire cam slot 20221. In this embodiment, the outer diameter of the first roller 20211 is equal to the slot width of the cam slot 20221 or the outer diameter of the first roller 20211 is slightly smaller than the width of the cam slot 20221, thereby ensuring the stability of the entire mechanism.

[0039] In one embodiment, Figure 2 and Figure 3 As shown, the translation assembly 300 includes a second guide rail 305 and a second slider 304, the second guide rail 305 is horizontally fixedly arranged on the base 100, the second slider 304 is adapted to the second guide rail 305, and the second slider 304 is slidably arranged on the second guide rail 305, wherein the push plate 301 is fixedly connected to the second slider 304, and the second slider 304 reciprocates along the second guide rail 305 to realize the cyclic action of the push plate 301 to push the material back and forth. In this embodiment, the reciprocating movement of the second slider 304 can be realized by a screw slider structure, a pneumatic guide slider structure or a hydraulic structure, and the reciprocating movement of the second slider 304 is realized by controlling the forward and reverse rotation of the screw or the flow direction of the airflow or hydraulic liquid. It can be understood that the movement mode of the second slider 304 and the selection of the power device are not controlled by the present invention, and it is only necessary to realize the axial reciprocating movement of the second slider 304 along the second guide rail 305.

[0040] Furthermore, if Figure 7 and Figure 8As shown, the translation assembly 300 also includes a second swing arm 303 and a first swing arm 302, wherein one end of the second swing arm 303 is hinged on the base 100, and the other end of the second swing arm 303 is movably connected to the second slider 304, and a swinging slide groove 3032 is provided on the second swing arm 303, as shown in FIG. Fig. 9 As shown, a second roller 3021 is provided at one end of the first rocker arm 302, and the diameter of the second roller 3021 is adapted to the slot width of the swinging slide 3032, and the other end of the first rocker arm 302 is fixedly connected to the first transmission shaft 103. Specifically, a third hinge hole is provided at one end of the second rocker arm 303, and a second rotating shaft is provided on the base, and the second rotating shaft is rotatably arranged relative to the base, and the second rocker arm is connected to the second rotating shaft 102 through the third hinge hole 3033, so that the second rocker arm 303 can rotate with the second rotating shaft 102 as a fulcrum. Optionally, the second rotating shaft 102 can also be fixedly arranged relative to the base 100, in which case it is sufficient to hinge the second rocker arm 303 on the second rotating shaft 102, and the second roller 3021 can be rotatably arranged or fixedly arranged relative to the second rocker arm 302. In this embodiment, the second roller 3021 is rolled relative to the second rocker arm 303 to reduce the friction resistance between the first rocker arm 302 and the second rocker arm 303.

[0041] Further, a second slide groove 3031 is provided at one end of the second swing arm 303 close to the second slider 304, and a third roller 3041 adapted to the second slide groove 3031 is provided on the second slider 304, and the third roller 3041 can slide relatively along the second slide groove 3031. Specifically, since the second slider 304 moves horizontally and the second swing arm 303 swings around the third hinge 3033 hole, the connection between the second swing arm 303 and the second slider 304 needs to move axially, so the second slide groove 3031 is provided, and the third roller 3041 is provided on the second slider 304, so that the second swing arm 303 can move axially relative to the second slider 304. The third roller 3041 can be rotatably arranged or fixedly arranged relative to the second slider 304, and the diameter of the third roller 3041 is the same as or slightly smaller than the groove width of the second slide groove 3031. Optionally, the second sliding block 304 and the second swing arm 303 may be hinged, and in this case, the second swing arm 303 needs to be configured as a telescopic rod structure.

[0042] In one embodiment, in order to reduce the installation size of the cam assembly 202 on the lifting assembly 200, the length of the first swing arm 2021 is reduced, such as Figure 1In the direction shown, the first rotating shaft 102 is located above the second rotating shaft 104, and the first transmission shaft 103 is located between the first rotating shaft 102 and the second rotating shaft 104. Since the lowest position of the connection point between the first connecting rod 2023 and the first swing arm 2021 can be confirmed, in order to avoid interference between the first swing arm 2021 and the first transmission shaft 103 and ensure that the required size of the first swing arm 303 is relatively small, the first rotating shaft 102 is arranged above the first transmission shaft 103, and when the first roller 20211 is located in the feeding section 202211, a spacing is provided between the first swing arm 2021 and the first transmission shaft 103 to avoid interference.

[0043] In one embodiment, the straight feed upward pushing mechanism also includes a feed depth regulator 400 located on one side of the feeder support plate 2011. The feed depth regulator 400 is mainly used to adjust products of different sizes so that the available size of the feeder support plate 2011 is consistent with the product size.

Specifically, the feed depth regulator 400 includes a plurality of spaced baffles 406 and a transverse shift assembly. The transverse shift assembly is disposed on the base 100, and the spaced baffles 406 are disposed on the transverse shift assembly. A plurality of spaced-apart make-way slots 20111 are disposed on the feeder support plate 2011, such as Fig.10 As shown, the position of the clearance groove 20111 corresponds to the position of the baffle 406, so that the baffle 406 can move along the length direction of the clearance groove 20111, thereby adjusting the feeding depth. Fig.11As shown, the transverse movement assembly includes an adjusting knob 401, an adjusting shaft 402 coaxially arranged with the adjusting knob 401, the adjusting shaft 402 is rotatably arranged on the base 100, and an adjusting gear 403 fixedly connected is arranged in the direction of the adjusting shaft 402, and an adaptable adjusting rack 404 is arranged on the adjusting gear 403, and the adjusting rack 404 has a certain length so that the movement of the adjusting rack 404 can meet the adjustment of the size of the feed depth regulator 400, and a symmetrically distributed first slide groove 105 is arranged on the base 100, and the first slide groove 105 is arranged horizontally, and the adjusting rack 404 is partially engaged with the first slide groove 105 so that the adjusting rack 404 moves along the first slide groove 105, and a fixedly connected fixed shaft 405 is provided on the adjusting rack 404, and a plurality of spaced baffles 406 are fixedly arranged on the fixed shaft 405. In this embodiment, the adjusting rack 404 and the adjusting gear 403 are both two and symmetrically arranged between the side plates of the base 100. By turning the adjustment knob 401, the baffle 406 can be synchronously entered into the clearance groove 20111 or separated from the clearance groove 20111, so as to adjust the size. In this embodiment, the structure of the baffle 406 is an L-shaped thin sheet structure. When the first roller position 20211 is in the unloading section 202213, one side of the L-shaped baffle 406 is coplanar with the lifting device support plate 2011, further supporting the product and transferring it to the next process. In this embodiment, the baffles 406 are evenly distributed, that is, the preset spacing 407 between the baffles is equal.

At this time, the first roller 20211 is located in the loading section 202211, and at the same time, the first transmission shaft 103 drives the second swing arm 303 to move the push plate 301 to the side of the lifting device support plate 2011; when the first roller 20211 moves from the loading section 202211 to the ascending section 202212, the lifting device support plate 2011 moves upward. The first roller 20211 moves to the unloading section 202213, and the lifting device support plate 2011 rises to the highest point and remains stationary. The pushing plate 301 pushes the packaging box off the lifting device support plate 2011 and moves to the next process. At this time, the first roller 20211 enters the descending section 202214, and the lifting device support plate 2011 descends to a position flush with the discharge port of the conveyor belt 101, and the pushing plate 301 begins to return to the initial position, that is, at Figure 1In the direction, at the position on the left side of the lifter pallet 2011, when the first roller 20211 enters the loading section 202211 again, the lifting and pushing process of the previous package box is completed, and the cyclic lifting and pushing process of the next package box is about to begin. The conveying interval time of the package box is one rotation cycle of the power wheel 2022.
