Abstract
Description
Technical Field
[0001] This application relates to the field of packaging machinery technology, and in particular to a pusher for an anti-slip and anti-collision cartoning machine. Background Technology
[0002] In the field of packaging machinery technology, cartoning machines, as key equipment for achieving automated product packaging, are widely used in industries such as pharmaceuticals and food. They are mainly used to automatically pack products such as strip packets, medicine bottles, and composite film pouches, along with accompanying instructions, into cartons. The pusher head, as the core actuator of the cartoning machine, directly affects the stability of product pushing and the packaging quality through its structural design.
[0003] Current cartoning machine pushers generally adopt a universal planar structure design, which has significant drawbacks when handling products of specific shapes. Taking strip-shaped products as an example, when the pusher pushes the strip bundles into the small box, due to the lack of effective limiting and guiding structures on both sides of the planar pusher, the strips on both sides are prone to slipping off the sides of the pusher due to uneven force during the pushing process, falling into the angled area between the pusher and the small box. As the pusher continues to advance, the strips in this angled area will be squeezed by the pusher and the box wall, causing the strips to wrinkle, break, or even get stuck. Utility Model Content
[0004] Therefore, it is necessary to provide a cartoning machine pusher that is anti-slip and anti-collision, addressing the issues of insufficient limiting of traditional general-purpose pushers when pushing easily scattered products, leading to product breakage, and the damage to packaging containers caused by defects in the front-end structural design.
[0005] According to one aspect of this application, a pusher head for an anti-slip and anti-collision cartoning machine is provided, comprising a pusher head body detachably mounted on the output end of the pusher arm of the cartoning machine; symmetrical material trough guide rails are provided on the outer walls of both sides of the pusher head body along the pushing direction, and the pusher head body reciprocates within the material trough via the material trough guide rails; the front end of the pusher head body includes a material pushing surface perpendicular to the pushing direction, and the pusher head body pushes the product to be packaged into the packaging box via the material pushing surface; the outer end of the material trough guide rail is also provided with a limiting block protruding from the material pushing surface, and the pusher head body gathers and limits the product to be packaged via the limiting blocks on both sides; the top of the pusher head body is also provided with an anti-collision inclined surface located above the material pushing surface, the anti-collision inclined surface is inclined away from the pushing direction of the pusher head body, and the anti-collision inclined surface is connected to the material pushing surface; the pusher head body guides the product to be packaged smoothly into the packaging box via the anti-collision inclined surface.
[0006] In one embodiment, the inner wall of the limiting block is provided with a transition portion, and the distance between the two limiting blocks gradually increases from the material pushing surface to the transition portion. The push head body restricts the abnormal sliding of the product to be packaged through the transition portions on both sides.
[0007] In one embodiment, the anti-collision ramp forms a 35° angle with the material pushing surface on the pusher body, and the width of the anti-collision ramp is consistent with the width of the material pushing surface.
[0008] In one embodiment, the bottom height of the anti-collision ramp is adapted to the opening height of the packaging box, and the pusher body guides the product smoothly into the packaging box through the anti-collision ramp and avoids impacting the edge of the packaging box.
[0009] In one embodiment, the rear end of the pusher body is provided with a mounting and positioning surface perpendicular to the pushing direction. A vertical pusher fixing groove is formed on the outer wall of the mounting and positioning surface, and the pusher fixing groove extends upward through the top of the pusher body. A pusher limiting cavity communicating with the pusher fixing groove is also formed below the mounting and positioning surface. The pusher body is positioned to the output end of the cartoning machine pusher arm through the pusher fixing groove and the pusher limiting cavity.
[0010] In one embodiment, the pusher fixing groove has a pusher fixing inner hole aligned with the pushing direction, and the anti-collision inclined surface has a pusher fixing outer hole coaxial with the pusher fixing inner hole; the diameter of the pusher fixing outer hole is larger than the diameter of the pusher fixing inner hole, and the pusher body is fixed again to the output end of the cartoning machine pusher arm through the pusher fixing inner hole and the pusher fixing outer hole.
[0011] In one embodiment, the transition portion is designed with smooth rounded corners.
[0012] In one embodiment, the feed trough guide rail, the limiting block, and the pusher body are integrally formed.
[0013] In one embodiment, the pusher body is made of engineering plastic.
[0014] In one embodiment, the surface roughness Ra of the anti-collision ramp is ≤1.6μm.
[0015] This application has the following beneficial effects:
[0016] 1. This application utilizes symmetrical limiting blocks on both sides to create physical limiting boundaries for the product to be packaged, preventing the product strips from sliding out to the sides during operation. This solves the problem of product strips slipping during the pushing process, reducing waiting time between processes and the possibility of incorrect identification. The transition section provided on the inner side of the limiting blocks effectively reduces stress concentration when the product strips contact the limiting blocks during pushing, preventing edge wear or tearing of the product due to rigid edges. Furthermore, the lateral constraint effect of the limiting blocks precisely restricts the lateral displacement of the product strips, preventing them from sliding into the angled area between the pusher head and the packaging box and being crushed. This design improves the overall efficiency and packaging effect of the packaging production line.
[0017] 2. During operation, the 35° anti-collision slope at the front end of this application, through its inclined guiding design, transforms the rigid collision between the pusher body and the packaging box into a sliding contact on the slope, thus avoiding damage to the edge of the packaging box caused by the pushing force of the pusher body, thereby reducing the operating cost of the production line.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0025] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0026] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0029] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0030] See Figures 1-4 , Figures 1-4 This illustration shows a schematic diagram of an anti-slip and anti-collision carton pusher according to an embodiment of this application. It includes a pusher body 1, which is detachably mounted on the output end of the carton pusher arm. Symmetrical material guide rails 2 are provided on the outer walls of both sides of the pusher body 1 along the pushing direction. The pusher body 1 reciprocates within the material trough via the material guide rails 2. The front end of the pusher body 1 includes a material pushing surface 5 perpendicular to the pushing direction. The pusher body 1 pushes the product to be packaged into the carton via the material pushing surface 5. Limiting blocks 3 protruding from the material pushing surface 5 are also provided at the outer ends of the material guide rails 2. The pusher body 1 gathers and limits the product to be packaged via the limiting blocks 3 on both sides. An anti-collision inclined surface 7 is also provided on the top of the pusher body 1, located above the material pushing surface 5. The anti-collision inclined surface 7 is inclined away from the pushing direction of the pusher body 1 and is connected to the material pushing surface 5. The pusher body 1 guides the product to be packaged smoothly into the carton via the anti-collision inclined surface 7.
[0031] During operation, the packaged strips are conveyed to the front end of the material pushing surface 5 of the pusher body 1 via a chain conveyor chute, and positioned on the pushing path of the pusher body 1. During packaging, the external cartoning machine pusher arm pushes the pusher body 1 along the chute towards the packaging box. During pushing, limit blocks 3 on both sides of the pusher body 1 restrict the lateral movement of the packaged strips. Furthermore, during pushing, the anti-collision ramp 7 contacts the upper edge of the packaging box opening. At this time, the material pushing surface 5 pushes the packaged strip into the opening of the packaging box. The 35° inclined anti-collision ramp 7 guides the packaged strip smoothly into the packaging box, preventing damage to the packaging box caused by a right-angle impact from the top of the material pushing surface 5.
[0032] See appendix Figure 1 and attached Figure 4 The inner wall of the limiting block 3 is provided with a transition part 4. The distance between the two limiting blocks 3 gradually increases from the material pushing surface 5 to the transition part 4. The push head body 1 restricts the abnormal sliding of the product to be packaged through the transition parts 4 on both sides.
[0033] In some embodiments, the limiting block 3 extends vertically along the material trough guide rail 2 toward the pushing direction of the pusher body 1. The limiting block 3 is designed with a height of 3mm and a thickness of 2mm, and the transition part 4 is designed with a rounded corner with a radius of R1.5. The inner side of the transition part 4 is a smooth plane. This design can reduce friction damage to the strip during the packaging operation.
[0034] See appendix Figure 1 and attached Figure 3 The anti-collision inclined surface 7 forms an angle of 25°-45° with the material pushing surface 5 on the pusher body 1, and the width of the anti-collision inclined surface 7 is consistent with the width of the material pushing surface 5.
[0035] In some embodiments, the width of the anti-collision ramp 7 is consistent with that of the pusher body 1, both being 50mm. The acute angle between the anti-collision ramp 7 and the plane containing the material pushing surface 5 is between 25° and 45°, preferably 35°. A suitable tilt angle can be obtained through a limited number of tests in actual production. Furthermore, the bottom of the anti-collision ramp 7 is 15mm above the bottom of the pusher body 1, which is consistent with the opening height of a standard packaging box. Therefore, during the pushing process, as the material pushing surface 5 pushes the strip into the opening of the packaging box, the anti-collision ramp 7 can slightly open the opening of the packaging box. This design can further improve the stability during packaging operations.
[0036] The width of the anti-collision ramp 7 is the width of the left and right sides of the material pushing surface 5 perpendicular to the pushing direction.
[0037] See appendix Figure 1 and attached Figure 3 The bottom height of the anti-collision ramp 7 is adapted to the opening height of the packaging box. The pusher body 1 guides the product smoothly into the packaging box through the anti-collision ramp 7 and avoids impacting the edge of the packaging box.
[0038] In some embodiments, if the bottom height of the anti-collision ramp 7 is too large or too small, it will be detrimental to the packaging operation. In order to improve the packaging effect, the bottom height of the anti-collision ramp 7 is adapted to the opening height of the packaging box.
[0039] See appendix Figure 2 - Appendix Figure 3 The rear end of the pusher body 1 is provided with an installation positioning surface 6 perpendicular to the pushing direction. A vertical pusher fixing groove 8 is provided on the outer wall of the installation positioning surface 6, and the pusher fixing groove 8 extends upward through the top of the pusher body 1. A pusher limiting cavity 11 communicating with the pusher fixing groove 8 is also provided below the installation positioning surface 6. The pusher body 1 is positioned to the output end of the cartoning machine pusher arm through the pusher fixing groove 8 and the pusher limiting cavity 11.
[0040] In some embodiments, when the pusher body 1 is disassembled or replaced, a quick-locking structure is provided on the mounting and positioning surface 6 to allow for quick installation onto the output end of the cartoning machine push arm. During installation, the positioning rod at the end of the cartoning machine push arm is directly inserted into the pusher limiting cavity 11, and the mounting surface on the push arm is inserted into the pusher fixing groove 8. This allows for quick positioning of the pusher body 1 and prevents accidental loosening. Depending on the actual structure of the cartoning machine push arm, the pusher fixing groove 8 is positioned in the center or offset to one side.
[0041] See appendix Figure 1 and attached Figure 3 The pusher fixing groove 8 has a pusher fixing inner hole 9 that is aligned with the pushing direction, and the anti-collision inclined surface 7 has a pusher fixing outer hole 10 that is coaxial with the pusher fixing inner hole 9. The diameter of the pusher fixing outer hole 10 is larger than the diameter of the pusher fixing inner hole 9. The pusher body 1 is then fixed to the output end of the cartoning machine pusher arm through the pusher fixing inner hole 9 and the pusher fixing outer hole 10.
[0042] In some embodiments, after the pusher body 1 is initially positioned and installed, the pusher fixing groove 8 is then fixedly connected to the cartoning machine pusher arm by a screw passing through the pusher fixing outer hole 10. At this time, the screw nut is located inside the pusher fixing outer hole 10, and the screw body is located inside the pusher fixing inner hole 9 and threadedly connected to the cartoning machine pusher arm. To accommodate the parts, it is fixed to the cartoning machine pusher arm with M6 bolts. M6 bolts are bolts with a nominal diameter of 6mm to ensure the positional accuracy and structural stability of the pusher body 1 during the pushing process.
[0043] See appendix Figure 1 The transition section 4 features a smooth, rounded corner design.
[0044] In some embodiments, the lateral limiting boundary is a transverse constraint area formed by the two limiting blocks 3 on both sides, which restricts the lateral displacement of the packaged product during the pushing process and prevents it from sliding into the angle area between the pusher body 1 and the packaging box and being squeezed. During the pushing process, in order to avoid excessive friction causing damage to the outer surface of the packaged product, the transition part 4 is designed with a smooth rounded corner structure.
[0045] See appendix Figure 1 The feed trough guide rail 2, the limit stop block 3, and the pusher body 1 are integrally formed.
[0046] In some embodiments, the pusher body 1 is the core actuator of the cartoning machine, which pushes the product from the trough into the packaging box through mechanical movement. Its structural design directly affects the stability of product pushing and the packaging quality. The one-piece molding structure means that the limiting block 3 and the pusher body 1 are processed by a single mold or formed in one step, without splicing or assembly links, thereby ensuring structural strength and stability and reducing motion errors caused by connection gaps.
[0047] See appendix Figure 1 The main body of the pusher head 1 is made of engineering plastic.
[0048] In some embodiments, the pusher body 1 is the core load-bearing structure of this application. It is integrally molded from PA66 nylon material, integrating a front anti-collision ramp 7 and two side limiting blocks 3. It is connected to the cartoning machine pusher arm through a rear mounting structure to realize the product pushing function. PA66 nylon is the common name for polyhexamethylene adipamide (Polyamide 66). This material is an engineering plastic with high strength, wear resistance, and light weight, making it suitable for manufacturing the pusher body 1, which needs to withstand certain mechanical loads.
[0049] See appendix Figure 1 The surface roughness Ra of the anti-collision inclined surface 7 is ≤1.6μm.
[0050] In some embodiments, rigid collision refers to the direct, unbuffered impact between the right-angled tip of a traditional pusher and the edge of a packaging box, which can easily lead to damage or tearing of the packaging box's folded edges. This application transforms this into sliding contact through the anti-collision ramp 7, achieving flexible buffering. Surface roughness is a surface smoothness index. Ra (arithmetic mean deviation of the profile) is a parameter that measures surface roughness. The smaller the value, the smoother the surface, which can reduce the frictional resistance between the product and the ramp, and avoid product damage caused by a rough surface.
[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
