Description

Technical Field

[0001] This application belongs to the field of cartoning machines, and particularly relates to a material pushing mechanism for a cartoning machine. Background Technology

[0002] In traditional cartoning machines, the feeding mechanism often fails to push material into the box because the material is blocked by the box's edge at the opening. This phenomenon is very common and seriously affects the efficiency and reliability of cartoning. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this application is to provide a feeding mechanism for a cartoning machine to solve the technical problem of low cartoning efficiency in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a feeding mechanism for a cartoning machine, comprising:

[0005] First linear guide;

[0006] A horizontal slide block is slidably connected to the first linear rail;

[0007] The second linear guide is vertically mounted on the horizontal slide and is perpendicular to the first linear guide;

[0008] A vertical slide block is slidably connected to the second linear rail;

[0009] The guiding assembly includes a guide seat spaced apart from the first linear rail, and a roller rotatably mounted on the vertical slide. The guide seat has a guide groove for the roller to move. The guide groove has an arc-shaped segment with its axis perpendicular to the first linear rail and the second linear rail, respectively, and a horizontal segment connected to one end of the arc-shaped segment and parallel to the first linear rail.

[0010] A pusher head is connected to the vertical slide and is used to abut against the target material in the extension direction of the first linear guide;

[0011] A pressure plate is attached to the pusher head and is used to abut against the target material in the extension direction of the second linear guide.

[0012] Optionally, the pressure plate is connected to the top of the pusher in the extending direction of the second linear guide.

[0013] Optionally, the thickness direction of the pressure plate is parallel to the extension direction of the second linear guide.

[0014] Optionally, the cartoning machine pushing mechanism further includes a support base, a push rod, a spring, and a safety pin;

[0015] The support base is connected to the vertical slide block. The push rod moves through the support base and can slide relative to the support base along the extension direction of the first linear guide. The axis of the spring is perpendicular to the moving direction of the push rod, and the two ends of the spring are respectively connected to the support base and the safety pin. The side of the safety pin away from the spring abuts against the support base and enters the moving path of the push rod. An inclined surface is also formed on the safety pin for abutting against the end of the push rod. The normal direction of the inclined surface faces the push rod. The push head is connected to the push rod.

[0016] Optionally, the end of the push rod is formed with a protrusion perpendicular to its own direction of movement, and a step is formed on the support for abutting against the protrusion;

[0017] The protrusion is positioned between the safety pin and the step in the direction of movement of the push rod.

[0018] Optionally, the cartoning machine's feeding mechanism further includes guide wheels rotatably mounted on the support base;

[0019] The guide wheels abut against opposite sides of the push rod in the extension direction of the second linear guide and are used to provide sliding guidance for the push rod.

[0020] Optionally, multiple sets of guide wheels are spaced apart in the direction of movement of the push rod.

[0021] Optionally, the cartoning machine pushing mechanism further includes a position sensor connected to the support base and used to detect the movement position of the push rod.

[0022] Optionally, the cartoning machine's feeding mechanism further includes a grooved cam and rollers;

[0023] The grooved cam forms a drive groove of a preset shape around its own central axis. The roller is movably mounted in the drive groove and can be guided by the drive groove. The horizontal slide is driven by the roller and can be driven by the roller to reciprocate on the first linear guide.

[0024] The beneficial effects of the carton-packing machine pushing mechanism provided in this application are as follows: Compared with the prior art, in the carton-packing machine pushing mechanism provided in this application, when the horizontal slide moves horizontally along the first linear rail, the roller can move in the guide groove of the guide seat and gradually move from the arc section to the horizontal section. When the roller moves in the arc section, it can be constrained by the groove wall and forced to move vertically downward along the second linear rail. In this way, the pusher and the pressure plate fixed thereon can also descend synchronously and make the pressure plate press against the top of the target material first. As the horizontal slide continues to move forward, the roller enters the horizontal section of the guide groove. At this point, the vertical slide stops moving downwards, the pusher head pushes the material horizontally, and the pressure plate can continuously press against the target material and maintain its stable posture. Since the pressure plate presses the material tightly against the conveying plane throughout the pushing process, the height of the material front end is forcibly reduced to below the edge of the box opening. When the pusher head advances horizontally, the material slides into the target box in a flat state under the pressure of the pressure plate. This can completely avoid the collision and interference between the material front end and the edge of the box and ensure smooth box entry, thereby enabling the pushing mechanism of the cartoning machine in this application to achieve a high cartoning efficiency, which is far superior to the prior art.

[0035] Please refer to the following: Figures 1 to 4 The following describes a feeding mechanism for a cartoning machine according to an embodiment of this application. This feeding mechanism includes a first linear guide 101, a horizontal slide 102, a second linear guide 103, a vertical slide 104, a guide assembly, a pusher head 108, and a pressure plate 109. Wherein:

[0036] A horizontal slide block 102 is slidably connected to a first linear guide 101; a second linear guide 103 is vertically mounted on the horizontal slide block 102 and perpendicular to the first linear guide 101; a vertical slide block 104 is slidably connected to the second linear guide 103; a guiding assembly includes a guide seat 105 spaced apart from the first linear guide 101, and a roller 106 rotatably mounted on the vertical slide block 104. A guide groove 107 is formed on the guide seat 105 for the roller 106 to move. The guide groove 107 forms an arc-shaped segment 171 with its axis perpendicular to the first linear guide 101 and the second linear guide 103, respectively, and also forms a horizontal segment 172 connected to one end of the arc-shaped segment 171 and parallel to the first linear guide 101; a pusher 108 is connected to the vertical slide block 104 and is used to abut against the target material 201 in the extension direction of the first linear guide 101; a pressure plate 109 is connected to the pusher 108 and is used to abut against the target material 201 in the extension direction of the second linear guide 103.

[0037] According to the structure provided in this embodiment, in the feeding mechanism of the cartoning machine provided in this embodiment, when the horizontal slide 102 moves horizontally along the first linear rail 101, the roller 106 can move within the guide groove 107 of the guide seat 105 and gradually move from the arc-shaped section 171 to the horizontal section 172. When the roller 106 moves in the arc-shaped section 171, it can be constrained by the groove wall to force the vertical slide 104 to move vertically downward along the second linear rail 103. In this way, the pusher head 108 and the pressing plate 109 fixed thereon can also descend synchronously and make the pressing plate 109 press against the top of the target material 201 first. As the horizontal slide 102 continues to move forward, the roller 106 enters the guide groove 107. In the horizontal section 172, the vertical slide 104 stops moving downwards, the pusher 108 pushes the material horizontally, and the pressure plate 109 can continuously press against the target material 201 and maintain its stable posture. Since the pressure plate 109 presses the material tightly against the conveying plane throughout the pushing process, the height of the material front end is forcibly reduced to below the edge of the target box 202. When the pusher 108 advances horizontally, the material slides into the target box 202 in a flat state under the pressure of the pressure plate 109. This can completely avoid the collision interference between the material front end and the edge of the box and ensure smooth box entry, thereby helping the pushing mechanism of the cartoning machine in this embodiment to form a high cartoning efficiency, which is far superior to the prior art.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The pressure plate 109 is connected to the top of the pusher head 108 in the extending direction of the second linear guide 103. According to the structure provided in this embodiment, the pressure plate 109 connected to the top of the pusher head 108 can form a compact connection structure between the pressure plate 109 and the pusher head 108 in the vertical direction. This can effectively avoid interference between the pressure plate 109 and the target material 201, thereby further improving the boxing efficiency of the boxing machine pusher mechanism in this embodiment.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The thickness direction of the pressure plate 109 is parallel to the extension direction of the second linear guide 103. According to the structure provided in this embodiment, the thickness direction being parallel to the extension direction of the second linear guide 103 allows the pressure plate 109 to make more sufficient contact with the target material 201, which is also beneficial to further improve the boxing efficiency of the boxing machine pushing mechanism in this embodiment.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The feeding mechanism of the cartoning machine also includes a support base 110, a push rod 111, a spring 112, and a safety pin 113. The support base 110 is connected to a vertical slide 104. The push rod 111 moves through the support base 110 and can slide relative to the support base 110 along the extension direction of the first linear guide 101. The axial direction of the spring 112 is perpendicular to the moving direction of the push rod 111, and both ends of the spring 112 are respectively connected to the support base 110 and the safety pin 113. The side of the safety pin 113 away from the spring 112 abuts against the support base 110 and enters the moving path of the push rod 111. An inclined surface 114 is also formed on the safety pin 113 for abutting against the end of the push rod 111. The normal direction of the inclined plane 114 faces the push rod 111, and the push head 108 is connected to the push rod 111. Here, the part of the support seat 110 used to accommodate the safety pin 113 and the spring 112 and to set the step 116 (see below) can be an integral structure with the support seat 110 or a separate structure. In this embodiment, a separate structure is adopted, that is, an additional block 1101 is connected to the outer end of the support seat 110 by fasteners. The safety pin 113 and the spring 112 are accommodated in the additional block 1101 and the additional block 1101 and the side wall of the support seat 110 work together to guide and limit the safety pin 113. The step 116 is set on the additional block 1101.

[0041] According to the structure provided in this embodiment, when the pusher 108 encounters resistance while pushing the target material 201, causing the pusher 111 to be obstructed, the end of the pusher 111 can decompose the horizontal pushing force into components in the extension direction of the first rail 101 and the extension direction of the second rail 103 by squeezing the inclined surface 114 on the safety pin 113. These components can overcome the elastic force of the spring 112 and force the safety pin 113 to exit the movement path of the pusher 111. In this way, the pusher 111 can retract relative to the support seat 110, thereby immediately disconnecting the power chain between the pusher 111 and the driving horizontal slide 102, avoiding overload damage to the drive mechanism or failure of the pusher 111 due to continuous force deformation. This also helps to further improve the reliability of the feeding mechanism of the cartoning machine in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The end of the push rod 111 has a protrusion 115 with its direction of protrusion perpendicular to its own moving direction, and a step 116 is formed on the support base 110 for abutting against the protrusion 115; the protrusion 115 is arranged between the safety pin 113 and the step 116 in the moving direction of the push rod 111. According to the above structure provided in this embodiment, the support base 110 can push the push rod 111 stably close to the target box 202 by the inclined surface 114 on the preservation pin, and can also drive the push rod 111 stably away from the target box 202 by the step 116 abutting against the protrusion 115. This is also conducive to further improving the reliability and boxing efficiency of the feeding mechanism of the cartoning machine in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The cartoning machine's feeding mechanism also includes guide wheels 117 rotatably mounted on the support base 110. The guide wheels 117 abut against opposite sides of the push rod 111 in the extending direction of the second linear guide 103 and provide sliding guidance for the push rod 111. According to the structure provided in this embodiment, the guide wheels 117 on the support base can significantly improve the movement stability of the push rod 111 relative to the support base 110, thus further preventing damage to the push rod 111 and consequently improving the cartoning efficiency of the feeding mechanism in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 Multiple sets of guide wheels 117 are spaced apart along the moving direction of push rod 111. According to the structure provided in this embodiment, the multiple sets of guide wheels 117 arranged along the moving direction of push rod 111 can help to further improve the boxing efficiency of the boxing machine pushing mechanism in this embodiment.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The cartoning machine's feeding mechanism also includes a position sensor 118 connected to the support base 110 and used to detect the movement position of the push rod 111. According to the structure provided in this embodiment, the sensor connected to the support base 110 can detect the movement position of the push rod 111 relative to the support base 110, allowing the operator to quickly be informed of feeding malfunctions. This also helps to further improve the cartoning efficiency of the feeding mechanism in this embodiment. It is understood that the position sensor 118 in this embodiment can be any commonly used sensor for detecting movement in the art, and will not be described in detail here.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The cartoning machine's feeding mechanism also includes a grooved cam 119 and a roller 120; the grooved cam 119 forms a preset-shaped drive groove 121 around its own central axis, the roller 120 is movably mounted in the drive groove 121 and can be guided by the drive groove 121 to move; the horizontal slide 102 is driven by the roller 120 to reciprocate on the first linear guide 101; here, please refer to the key reference. Figure 1 In this embodiment, the roller 120 is installed at the free end of the follower rocker arm 122, and the other end of the follower rocker arm 122 is fixedly installed on the rotating shaft 123. The horizontal slide 102 is movably hinged to one end of the rocker arm 124 through the connecting rod 125, and the other end of the rocker arm 124 is fixedly installed on the rotating shaft 123.

[0047] According to the structure provided in this embodiment, during the continuous rotation of the grooved cam 119 around its own central axis, the roller 120 can drive the horizontal slide 102 to move quickly and stably on the first linear rail 101 by moving in the drive groove 121 along a predetermined path. This is also conducive to further improving the boxing efficiency of the boxing machine pushing mechanism in this embodiment.
