Description

Technical Field

[0001] The utility model relates to the technical field of case openers, and particularly discloses a carton compatible feeding mechanism for a case opener. Background Art

[0002] In current industrial production, carton opening operation is one of the common processes. However, the feeding mechanisms of traditional case openers often have many problems. The previous feeding mechanisms are relatively rigid in space utilization, usually only having a single vertical or horizontal rack design, and cannot be flexibly selected according to the characteristics of the actual site. In terms of operation, the traditional feeding mechanism lacks convenient manual adjustment and control design. When adjusting the equipment, complex tools and cumbersome steps are often required, which not only consumes a large amount of manpower and time, but also the operation process is laborious, seriously affecting production efficiency.

[0003] At the same time, for cartons of different sizes, the compatibility of the traditional feeding mechanism is poor. Whenever the carton specifications change, large-scale adjustments to the equipment are required, and even some key components need to be replaced. This not only increases the equipment adjustment cost, but also reduces production efficiency due to the time required for adjustment, and cannot quickly adapt to the market's demand for diversified carton specifications. In order to solve the deficiencies of the existing feeding mechanisms of case openers in terms of space utilization, operation convenience, and carton compatibility, the utility model aims to provide a more advantageous carton compatible feeding mechanism. Content of the Utility Model

[0004] In order to overcome the defects and deficiencies existing in the prior art, the purpose of the utility model is to provide a carton compatible feeding mechanism for a case opener.

[0005] To achieve the above purpose, a carton compatible feeding mechanism for a case opener includes a storage rack, and an adjusting device arranged on the storage rack. The adjusting device includes a first adjusting mechanism and a second adjusting mechanism. The first adjusting mechanism includes a fixed baffle arranged on the storage rack, a first baffle reciprocatingly arranged on the storage rack, and a first driving component arranged on the storage rack for driving the first baffle. The storage rack has a base frame. The second adjusting mechanism includes a mounting rack reciprocatingly arranged on the base frame, and a second driving component arranged on the base frame for driving the mounting rack. A second baffle is arranged on the mounting rack. The movement directions of the first baffle and the second baffle are arranged crosswise to form a first included angle. The fixed baffle and the first baffle respectively abut against the left and right sides of the carton, and the second baffle and the storage rack respectively abut against the upper and lower sides of the carton; the positions of the first baffle and the second baffle are adjustable, and the feeding mechanism can adapt to cartons of different sizes.

[0006] The vertical design extends in the vertical direction, which is beneficial to the natural falling or flowing of materials, occupies relatively less floor area, and is especially suitable for places with limited space. By setting adjustable first baffle and second baffle, it can adapt to cartons of different sizes, greatly improving the compatibility of the feeding mechanism with the carton specifications, and reducing the time and cost required for equipment replacement or adjustment due to changes in carton specifications. The design of the cross-movement direction of the first baffle and the second baffle can position and adjust the carton from two different dimensions, making the position of the carton more accurate and stable during the feeding process, and reducing the unpacking errors caused by the deviation of the carton position.

[0007] Furthermore, the first driving component includes a screw rod that is screwed and matched with the first baffle. A handle is provided at one end of the screw rod close to the first baffle. A bearing rack for supporting the carton by cooperating with the fixed baffle is provided on the storage rack. The end of the screw rod away from the first baffle is rotatably connected to the bearing rack.

[0008] The design of rotatingly connecting the screw rod with the first baffle makes the adjustment of the position of the first baffle more precise and stable. The handle provided at one end of the screw rod facilitates the operator to perform manual adjustment without the need for additional tools, and the operation is simple and fast, improving work efficiency. This structural design is simple, with low cost, and is easy to maintain and repair. Once a failure occurs or parts need to be replaced, the operation is relatively easy, reducing the maintenance cost and downtime of the equipment.

[0009] Furthermore, the number of screw rods is set to two. Sprockets are provided on the screw rods. The first baffle is arranged between the sprockets and the handle. A chain is provided between the two sprockets.

[0010] Setting two screw rods and realizing linkage through sprockets and chains ensures the synchronization of both sides of the first baffle during the movement, avoiding position deviation caused by unilateral movement, thereby improving the accuracy and stability of carton positioning. The design of the double screw rods enhances the overall strength and load-bearing capacity of the structure, and can support and adjust the first baffle more firmly. Especially when dealing with larger-sized or heavier cartons, it ensures the reliability and durability of the equipment. The transmission method of the sprockets and chains makes the operation more labor-saving and convenient. The operator can drive the two screw rods to rotate synchronously by rotating one handle, reducing the labor intensity and improving work efficiency.

[0011] Furthermore, a fixing block is provided on the second baffle. An adjusting part is provided on the fixing block. A locking piece is provided between the fixing block and the mounting rack. The fixing block is fixed on the mounting rack by the adjusting part abutting against the locking piece. The second baffle can be set to multiple pieces, and multiple second baffles can better abut against the carton for limiting.

[0012] The cooperation between the adjusting member and the locking piece makes the fixing of the fixing block on the mounting rack more firm and reliable, which can effectively prevent the second baffle from loosening or displacing during operation, thus ensuring the accuracy and stability of the position adjustment of the carton. This adjustable fixing method facilitates the installation, disassembly and position adjustment of the second baffle, and can quickly and flexibly change the position of the second baffle according to different carton specifications and feeding requirements, improving the adaptability and operation convenience of the equipment.

[0013] Furthermore, the second driving assembly has a guide rail arranged on the base frame, a slider connected to the mounting rack is arranged on the guide rail, and a locking member for locking the slider to the guide rail is arranged on the slider.

[0014] The cooperation between the guide rail and the slider provides precise guidance for the movement of the mounting rack, ensuring that the mounting rack and the second baffle can move smoothly along a predetermined straight track, thereby improving the accuracy and stability of the position adjustment of the carton. The locking member on the slider can lock the slider to the guide rail after the position of the mounting rack is adjusted, effectively preventing the mounting rack from accidentally moving due to vibration or external force during operation, and ensuring the reliability and stability of the equipment operation. It can adapt to different working conditions and carton specifications, and by flexibly adjusting the position of the mounting rack and locking it, the versatility and adaptability of the feeding mechanism are improved.

[0015] Furthermore, a guide rod is arranged on the storage rack, the guide rod is arranged between the fixed baffle and the bearing rack, and a pressing plate for abutting against a plurality of folded cartons is slidably arranged on the guide rod. The number of guide rods can be set to be multiple, and multiple guide rods can make the sliding of the pressing plate more stable.

[0016] Arranging multiple guide rods can provide guidance and support for the pressing plate from multiple directions, ensuring that the pressing plate always maintains a smooth and vertical movement track during sliding, avoiding tilting or jamming phenomena, and thus more effectively abutting against the carton to ensure the stable placement of the carton on the storage rack. The structure of the guide rod enhances the stability and balance of the pressing plate, making the pressure applied to the carton more evenly distributed, preventing the carton from being deformed or damaged due to excessive local stress, and improving the protection effect on the carton.

[0017] Furthermore, one end of the first baffle close to the carton feeding direction is bent to form a stop portion, and a stop member for abutting against the carton is arranged on the stop portion. The stop portion forms a plane for accommodating the carton, and the first baffle and the stop member on both sides of the stop portion can limit the front and rear sides of the carton below the carton. The stop member can be formed into a roller structure, and the roller structure can reduce the contact area between the carton and the stop member during feeding.

[0018] The plane formed by the stopping part can provide a stable supporting surface for the carton, keeping the carton in a horizontal state during transportation, avoiding tilting or shaking, and improving the stability of feeding. The front and back sides of the carton are limited by the first baffle and the stopping piece on both sides of the stopping part, effectively controlling the position of the carton in the horizontal direction, ensuring that the carton can be accurately transported to the designated position, and improving the accuracy of feeding. The stopping piece adopts a roller structure, which reduces the contact area between the carton and the stopping piece while reducing the frictional resistance, making the transportation of the carton smoother, reducing energy consumption, and improving the feeding efficiency.

[0019] Furthermore, the plane of the storage rack for storing materials is cross - arranged with the horizontal plane to form a second included angle, and the sum of the first included angle and the second included angle is 90°.

[0020] The plane of the storage rack is cross - arranged with the horizontal plane to form a second included angle, and it is complementary to the first included angle. This ingenious angle design can make the cartons flow more smoothly during feeding, reduce jamming and blockage, and improve the feeding efficiency. It is beneficial to utilize the gravity, allowing the cartons to move naturally in the direction of feeding under the action of the component force of their own gravity, saving additional power consumption and reducing energy costs.

[0021] Furthermore, a sensor is provided at one end of the first baffle close to the feeding direction of the carton, and the sensor is electrically connected to an external control console.

[0022] The setting of the sensor can monitor the feeding situation of the carton in real - time. When the carton reaches the designated position, it timely transmits a signal to the external control console to achieve precise control of the feeding process. It can timely detect abnormal situations during feeding, such as carton blockage, too fast or too slow feeding, etc., so as to make quick adjustments, reduce production failures and downtime. It helps to optimize the feeding rhythm, improve production efficiency, enable the carton - opening machine to continuously and stably obtain carton supply, and avoid affecting the production progress due to untimely feeding.

[0023] Furthermore, the storage rack can also be set as a horizontal storage rack. The horizontal storage rack has a first material - placing surface, a second material - placing surface, and a third material - placing surface for abutting against the cartons. The plane direction of the first material - placing surface is cross - arranged with the horizontal plane direction; the plane directions of the first material - placing surface, the second material - placing surface, and the third material - placing surface are perpendicular to each other.

[0024] The three material placement surfaces are perpendicular to each other, and the first material placement surface is arranged crosswise with the horizontal plane, which can provide stable support and resistance for the carton from different directions, greatly reducing the risks of shaking, tilting or even falling of the carton during storage and transportation, and ensuring the smoothness and safety of the feeding process. Due to the special layout of the three material placement surfaces, it can adapt to various cartons of different sizes and shapes. Whether it is a square, rectangular or irregularly shaped carton, it can be stably stored on this material placement rack, increasing the versatility of the feeding mechanism.

[0025] The beneficial effects of the present utility model: saving space, the vertical or horizontal storage rack can be flexibly selected according to the actual site, effectively utilizing the limited production space; convenient and labor-saving operation, through the design of the handle, adjusting parts, etc., it is convenient for manual adjustment and control; having good compatibility, it can adapt to cartons of different sizes, reducing the equipment adjustment cost and time caused by the change of carton specifications.

Detailed implementation manners

[0035] For the convenience of those skilled in the art to understand, the following further describes the present utility model in conjunction with embodiments and the attached drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0036] Please refer to Figures 1 to 8 As shown, a carton compatible feeding mechanism for an unpacking machine of the present utility model includes a storage rack 1 and an adjusting device 2 arranged on the storage rack 1. The adjusting device 2 includes a first adjusting mechanism 21 and a second adjusting mechanism 22. The first adjusting mechanism 21 includes a fixed baffle 211 arranged on the storage rack 1, a first baffle 212 reciprocatingly arranged on the storage rack 1, and a first driving assembly 213 arranged on the storage rack 1 for driving the first baffle 212. The storage rack 1 has a base frame 11. The second adjusting mechanism 22 includes a mounting rack 221 reciprocatingly arranged on the base frame 11 and a second driving assembly 222 arranged on the base frame 11 for driving the mounting rack 221. A second baffle 223 is arranged on the mounting rack 221. The movement directions of the first baffle 212 and the second baffle 223 are cross - arranged to form a first included angle 3.

[0037] During actual use, according to the size specification of the carton to be unpacked, first adjust the position of the first baffle 212 through the first driving assembly 213, and then adjust the position of the second baffle 223 by using the second driving assembly 222, so that a suitable space is formed between the first baffle 212 and the second baffle 223 to accommodate and position the carton. During the feeding process, the worker places the carton on the storage rack 1. Through the positioning of the first baffle 212 and the second baffle 223, it is ensured that each carton can be accurately conveyed to the feeding port of the unpacking machine, realizing efficient and accurate unpacking operations.

[0038] Specifically, the first driving component 213 includes a screw rod 2131 that is screwed and fitted with the first baffle 212. A handle 2132 is provided at one end of the screw rod 2131 close to the first baffle 212. A bearing frame 12 for cooperating with the fixed baffle 211 to support the carton is provided on the material storage rack 1. The end of the screw rod 2131 away from the first baffle 212 is rotatably connected to the bearing frame 12.

[0039] During actual use, in the operation process, the staff rotates the handle 2132 to drive the screw rod 2131 to rotate, thereby pushing the first baffle 212 to move smoothly on the material storage rack 1. When it is necessary to adapt to cartons of different sizes, simply rotate the handle 2132 easily to precisely adjust the position of the first baffle 212.

[0040] Specifically, the number of the screw rods 2131 is set to two. Sprockets 2133 are provided on the screw rods 2131. The first baffle 212 is arranged between the sprockets 2133 and the handle 2132. A chain 2134 is provided between the two sprockets 2133.

[0041] During actual use, in the actual operation, when an operator rotates one of the handles 2132, through the transmission of the sprockets 2133 and the chain 2134, the other screw rod 2131 can rotate synchronously. Under the synergistic effect of the sprockets 2133 and the chain 2134, the two screw rods 2131 push the first baffle 212 to move synchronously, so as to quickly and accurately adjust to the position adapted to the size of the carton. The whole process is stable and efficient, showing good synergistic adjustment performance.

[0042] Specifically, further, a fixing block 224 is provided on the second baffle 223. An adjusting member 225 is provided on the fixing block 224. A locking piece 226 is provided between the fixing block 224 and the mounting frame 221. The fixing block 224 is fixed on the mounting frame 221 by the adjusting member 225 abutting against the locking piece 226. The second baffle 223 can be provided in multiple numbers, and multiple second baffles 223 can better abut against the carton for limiting.

[0043] During actual use, in the actual operation, when it is necessary to fix the fixing block 224 on the mounting frame 221, the operator rotates the adjusting member 225 so that its end tightly abuts against the locking piece 226. Due to the friction and elastic deformation of the locking piece 226, the fixing block 224 is firmly fixed on the mounting frame 221. By rotating the adjusting member 225, the second baffle 223 can be precisely fixed at the position adapted to the size of the carton, thereby ensuring the accuracy and stability of the feeding. This fixing method is easy to operate and has a reliable fixing effect, and can meet the feeding requirements of different carton specifications.

[0044] Specifically, the second driving component 222 has a guide rail 2221 provided on the base frame 11. A slider 2222 connected to the mounting frame 221 is provided on the guide rail 2221, and a locking member 2223 for locking the slider 2222 to the guide rail 2221 is provided on the slider 2222.

[0045] During actual use, the slider 2222 connected to the mounting frame 221 adopts a ball slider 2222 structure and is filled with high-quality grease inside to ensure smooth sliding on the guide rail 2221. A manually operated locking member 2223 is provided on the slider 2222, and the locking member 2223 is an eccentric wheel with a handle 2132. During the actual working process, when the mounting frame 221 needs to move along the guide rail 2221, the operator loosens the eccentric wheel so that the slider 2222 can slide freely. After the mounting frame 221 moves to the designated position, the operator rotates the handle 2132 of the eccentric wheel to press the eccentric wheel tightly against the guide rail 2221, thereby locking the slider 2222 to the guide rail 2221 and fixing the position of the mounting frame 221.

[0046] Specifically, a guide rod 23 is provided on the storage rack 1. The guide rod 23 is arranged between the fixed baffle 211 and the carrier rack 12, and a pressing plate 24 for abutting and pressing a plurality of folded cartons is slidably provided on the guide rod 23. The number of the guide rods 23 can be set to be multiple, and the multiple guide rods 23 can make the sliding of the pressing plate 24 more stable.

[0047] During actual use, during actual operation, after the cartons are placed on the storage rack 1, the pressing plate 24 slides downward along the guide rod 23 and gently abuts against the surface of the cartons.

[0048] Specifically, further, one end of the first baffle 212 close to the carton feeding direction is bent to form a stop portion 2121, and a stop member 2122 for abutting against the carton is provided on the stop portion 2121. The stop portion 2121 forms a horizontal plane for accommodating the carton, and the front and rear sides of the carton can be limited by the first baffle 212 and the stop member 2122 on both sides of the stop portion 2121 below the carton. The stop member 2122 can be formed into a roller structure, and the roller structure can reduce the contact area between the carton and the stop member 2122 during feeding.

[0049] During actual use, one end close to the carton feeding direction is bent to form the stop portion 2121 through a precise processing technology. On the stop portion 2121, a stop member 2122 for abutting against the carton is installed. The plane formed by the stop portion 2121 can accommodate the carton, and the front and rear sides of the carton can be effectively limited below the carton through the first baffle 212 and the stop member 2122 on both sides of the stop portion 2121.

[0050] Specifically, the plane of the material storage rack 1 used for storing materials is cross-arranged with the horizontal plane to form a second angle 4, and the sum of the first angle 3 and the second angle 4 is 90°.

[0051] In actual use, this angle setting plays a significant role in actual operation. For example, when processing a batch of cartons with smaller specifications and lighter weight, the second angle 4 enables the cartons to slide more smoothly along the plane of the storage rack 1 with the assistance of gravity, reducing the residence time of the cartons on the storage rack 1 and improving the speed and efficiency of feeding.

[0052] Specifically, a sensor 2123 is provided at one end of the first baffle 212 close to the carton feeding direction, and the sensor 2123 is electrically connected to an external control console.

[0053] In actual use, during the actual feeding process, when the carton reaches the designated position of the first baffle 212, the sensor 2123 will immediately detect it and transmit the signal to the control console via the cable.

[0054] Specifically, the storage rack 1 can also be set as a horizontal rack 5, which has a first loading surface 51, a second loading surface 52 and a third loading surface 53 for contacting cartons, and the plane direction of the first loading surface 51 and the horizontal plane direction are cross-arranged; the plane direction of the first loading surface 51, the plane direction of the second loading surface 52 and the plane direction of the third loading surface 53 are perpendicular to each other.

[0055] In actual use, the three material loading surfaces are perpendicular to each other, and the first material loading surface 51 is arranged crosswise with the horizontal plane, which can provide stable support and resistance for the cartons from different directions, greatly reducing the risk of shaking, tilting or even falling of the cartons during storage and transportation, and ensuring the stability and safety of the feeding process. Due to the special layout of the three material loading surfaces, it can adapt to cartons of various sizes and shapes. Whether it is a square, rectangular or irregular shaped carton, it can be stably stored on this storage rack, increasing the versatility of the feeding mechanism.

[0056] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
