Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, and in particular to a packing machine. Background Technology

[0002] In agricultural production and logistics transportation, bran materials such as wheat, due to their loose texture, are prone to bulging and uneven surfaces after packaging. This unevenness makes the packages easily tilt and slip during warehouse stacking, increasing handling costs and potentially causing damage and material loss. Furthermore, the irregular shape of the packages results in low space utilization during vehicle transport, making it difficult to achieve the ideal loading capacity per layer, significantly reducing loading and transportation efficiency and increasing logistics costs.

[0003] To solve the above problems, the packages need to be compressed. Compression makes the packages more compact, reduces their volume, optimizes their shape, improves stacking stability, and thus improves loading and transportation efficiency.

[0004] However, current conventional packing operations mainly rely on manual labor. Manual labor is arduous and inefficient, unable to meet the demands of large-scale production and rapid logistics transportation; furthermore, it is difficult to maintain consistent pressure during manual packing, resulting in variations in the compaction degree of different packages and affecting product consistency. Utility Model Content

[0005] The purpose of this invention is to provide a packing machine to solve the technical problems of low efficiency and poor consistency of manual packing in the prior art.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A bagging machine, comprising:

[0008] Support components;

[0009] Two rows of opposing roller structures are installed on the support assembly, and a pressing channel is formed between the two rows of roller structures. The pressing channel has a feed end and a discharge end, and the spacing between the two rows of roller structures is adjustable.

[0010] Each row of roller structures includes multiple roller units spaced apart along the extension direction of the pressing channel. The spacing between two adjacent roller units is adjustable. At least one row of roller structures has a driving member for each roller unit. The driving member is used to drive the corresponding roller unit to rotate around its own axis, so as to convey the workpiece to be pressed from the feed end to the discharge end.

[0011] Preferably, the roller unit located on the upper side of the pressing channel is equipped with the driving member, and the roller unit located on the lower side of the pressing channel is passively rotated by the friction of the workpiece to be pressed.

[0012] Preferably, in the roller structure equipped with the driving member, each roller unit is provided with a transmission sprocket at its end, the transmission sprockets of multiple roller units are connected by a transmission chain, and the output end of the driving member is connected to any of the transmission sprockets.

[0013] Preferably, the support assembly includes two support frames arranged opposite each other, connected by a support rod, and each support frame contains a roller structure. The upper support frame is movably connected to the support rod, and the support frame can move along the axial direction of the support rod and be locked to the support rod.

[0014] Preferably, the support frame is provided with a guide groove along the extension direction of the pressing channel, the roller unit is slidably connected to the guide groove, and the roller unit and the guide groove are locked by a locking member.

[0015] Preferably, the bottom of the support assembly is provided with an adjustment mechanism on the side near the feed end. The adjustment mechanism can drive the side of the support assembly near the feed end to move vertically to adjust the angle between the pressing channel and the horizontal plane.

[0016] Preferably, the pressing machine further includes a guide plate, which is disposed at the discharge end and connected to the pressing channel. The angle of the guide plate relative to the axis of the pressing channel is adjustable.

[0017] Preferably, protective netting is provided on both sides of the compression channel.

[0018] Preferably, the outer surface of the roller unit is provided with a lubricating layer.

[0019] Preferably, the pressing machine further includes a monitoring component, which can acquire the motion state of the piece to be pressed in the pressing channel and control the drive component to run or stop based on the motion state.

[0020] The beneficial effects of this utility model are:

[0021] The pressing machine proposed in this utility model features a support component that provides stable support for the overall structure, ensuring a smooth pressing process. Two rows of opposing rollers with adjustable spacing can accommodate pieces of varying thicknesses. By adjusting the spacing, pieces of different specifications can be effectively compacted, improving the equipment's versatility. Each row of rollers consists of multiple roller units with adjustable spacing. The contact position of the roller units can be adjusted according to the specific shape of the pieces to be pressed and actual needs, resulting in more uniform pressing and improved pressing quality. At least one row of roller units is equipped with a drive unit, enabling the roller units to not only perform the extrusion function but also possess active conveying capabilities. After the packaged items enter the pressing channel from the feed end, the drive roller unit rotates around its own axis. The rotating roller unit, through friction with the outer surface of the packaged items, continuously and stably conveys the packages from the feed end to the discharge end, achieving continuous automatic pressing operation. This improves pressing efficiency, saves manpower compared to manual operation, and applies uniform pressure to the packages during conveying, helping to ensure consistent compaction of different packages.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1 The pressing machine provided in this embodiment of the utility model includes a support assembly 1 and a roller structure 2. Two rows of oppositely arranged roller structures 2 are installed on the support assembly 1, forming a pressing channel 21 between the two rows of roller structures 2. The pressing channel 21 has an inlet end 211 and an outlet end 212, and the spacing between the two rows of roller structures 2 is adjustable. Each row of roller structures 2 includes a plurality of roller units 22 spaced apart along the extension direction of the pressing channel 21, and the spacing between adjacent roller units 22 is adjustable. At least one row of roller structures 2 has a driving member for each roller unit 22, which drives the corresponding roller unit 22 to rotate around its own axis, conveying the workpiece 100 to be pressed from the inlet end 211 to the outlet end 212.

[0030] The pressing machine proposed in this utility model has a support component 1 that provides stable support for the overall structure, ensuring smooth pressing. Two rows of opposing roller structures 2 with adjustable spacing can accommodate pressing parts 100 of different thicknesses. By adjusting the spacing, different specifications of pressing parts 100 can be effectively compacted, improving the equipment's versatility. Each row of roller structures 2 consists of multiple roller units 22 with adjustable spacing. The contact position of the roller units 22 can be adjusted according to the specific shape of the pressing part 100 and actual needs, resulting in more uniform pressing and improved pressing quality. At least one row of roller structures 2 has roller units 22 equipped with a drive unit, enabling the roller units 22 to not only perform the extrusion function but also have active conveying capabilities. When the package 100 to be pressed enters the pressing channel 21 from the feed end 211, the drive roller unit 22 rotates around its own axis. The rotating roller unit 22, through friction with the outer surface of the package 100, continuously and stably conveys the package 100 from the feed end 211 to the discharge end 212, achieving continuous automatic pressing operation, improving pressing efficiency, saving manpower compared to manual operation, and applying uniform pressure to the package 100 during conveying, helping to ensure the consistency of compaction degree for different packages. In summary, this pressing machine, through the coordinated cooperation of the support component 1 and the roller structure 2, achieves efficient and uniform pressing operation, improving pressing efficiency and quality.

[0031] The working principle and specific structure of the pressing machine are explained below.

[0032] The support assembly 1 includes two support frames 11 arranged opposite to each other, and the two support frames 11 are connected by a support rod 12. Each support frame 11 is provided with a roller structure 2. The upper support frame 11 is movably connected to the support rod 12. The support frame 11 can move along the axial direction of the support rod 12 and be locked to the support rod 12.

[0033] Optionally, two sets of support rods 12 are provided on each side of the support frame 11. The support frame 11 and the support rods 12 are slidably connected. Locking bolts 112 are threadedly connected to the side wall of the support frame 11. The locking bolts 112 can abut against the support rods 12, thereby restricting the relative movement between the support frame 11 and the support rods 12. In use, when it is necessary to adjust the spacing between the two rows of roller structures 2, the locking bolts 112 are loosened, and the upper support frame 11 slides up and down along the axial direction of the support rods 12. When the appropriate spacing is reached, the locking bolts 112 are tightened, and the upper support frame 11 is locked on the support rods 12, ensuring that there is no positional change during the pressing process, thereby ensuring the stability and reliability of the pressing operation.

[0034] Furthermore, a guide groove 111 is provided on the support frame 11 along the extension direction of the pressing channel 21, and the roller unit 22 is slidably connected to the guide groove 111. The roller unit 22 and the guide groove 111 are locked by a locking member.

[0035] Specifically, sliders 221 are provided on both sides of the roller unit 22. The roller unit 22 is slidably connected to the guide groove 111 through the sliders 221. Fastening bolts are threaded onto the sliders 221, and the fastening bolts can abut against the inner wall of the guide groove 111, thereby restricting the relative movement between the sliders 221 and the guide groove 111. When it is necessary to adjust the distance between adjacent roller units 22, firstly, the fastening bolts are tightened and loosened. Then, the sliders 221 are moved within the guide groove 111 to adjust the distance between adjacent roller units 22. When the distance is adjusted to meet the requirements, the fastening bolts are tightened again to lock the sliders 221 within the guide groove 111, ensuring that the roller unit 22 will not move arbitrarily during the pressing process, thus ensuring the stability and uniformity of the pressing.

[0036] In other embodiments, hydraulic adjustment mechanisms or screw-nut transmission mechanisms can be installed on the two support frames 11 respectively to adjust the spacing between the two rows of roller structures 2. The spacing between each roller unit 22 can be adjusted using a gear and rack transmission or similar structure, which will not be elaborated upon here.

[0037] An adjustment mechanism 3 is provided on the bottom side of the support component 1 near the feed end 211. The adjustment mechanism 3 can drive the side of the support component 1 near the feed end 211 to move vertically to adjust the angle between the pressing channel 21 and the horizontal plane. By adjusting the angle of the pressing channel 21, it can better connect with the feeding equipment, adapt to various feeding scenarios, and enhance the compatibility and collaborative working ability of the pressing machine with other equipment.

[0038] Optionally, the posture adjustment mechanism 3 includes a hydraulic cylinder. The output end of the hydraulic cylinder is connected to the bottom of the support assembly 1 near the feed end 211. The hydraulic cylinder can push the support assembly 1 to move in the vertical direction, thereby adjusting the angle between the pressing channel 21 and the horizontal plane.

[0039] In other embodiments, the attitude adjustment mechanism 3 may also be an electric pump, a jack, etc., which will not be described in detail here.

[0040] Preferably, the pressing machine further includes a guide plate 4, which is disposed at the discharge end 212 and connected to the pressing channel 21. The angle of the guide plate 4 relative to the axis of the pressing channel 21 is adjustable, thereby adapting to the position and height of different subsequent processes or transfer equipment. By adjusting the angle of the guide plate 4, the packaged parts 100 can be smoothly and accurately placed at the target position after flowing out from the output end, avoiding material falling or deviating, ensuring the smooth flow of the packaged parts 100, and improving the continuity of the overall production process.

[0041] Specifically, the guide plate 4 is rotatably connected to the support assembly 1 via a movable hinge shaft, and an electric push rod is provided between the guide plate 4 and the support assembly 1. The electric push rod is mounted on the support assembly 1, and its output end is connected to the back of the guide plate 4. In use, the guide plate 4 is pushed or pulled around the hinge shaft by the extension end of the drive elevator push rod, thereby adjusting the angle of the guide plate 4 relative to the axis of the pressing channel 21.

[0042] The pressing process involves the roller unit 22 of the roller structure 2 rotating around its own axis to press and transport the workpiece 100 in the pressing channel 21.

[0043] In one approach, driving elements can be provided for both rows of roller structures 2, allowing the roller units 22 to rotate synchronously for pressing. Alternatively, driving elements can be provided for only one row of roller structures 2, allowing it to rotate actively, while the roller units 22 of the other row rotate passively due to friction from the workpiece 100 to be pressed.

[0044] In this embodiment, the roller unit 22 located on the upper side of the pressing channel 21 is equipped with a driving component, while the roller unit 22 located on the lower side of the pressing channel 21 passively rotates due to friction of the workpiece 100 to be pressed. By configuring the driving component on the roller unit 22 on the upper side of the pressing channel 21, the upper roller unit 22 can actively and stably provide power, effectively pushing the workpiece 100 to be pressed along the pressing channel 21 from the feed end 211 to the discharge end 212, ensuring the continuity and efficiency of the pressing process. At the same time, the lower roller unit 22 passively rotates due to friction of the workpiece 100 to be pressed. This design simplifies the overall structure, reduces the number of driving components used, and lowers equipment costs and maintenance complexity. Moreover, the combination of the upper active roller and the lower passive roller allows the package to be pressed 100 to be subjected to uniform pressure and friction in the pressing channel 21, which helps to compact the package to be pressed 100 more evenly, improve the consistency of pressing quality, and enable the package to be pressed 100 in different positions and batches to achieve a relatively similar degree of compaction.

[0045] Preferably, in the roller structure 2 equipped with a drive component, each roller unit 22 has a drive sprocket at its end. The drive sprockets of multiple roller units 22 are connected by a drive chain, and the output end of the drive component is connected to any one of the drive sprockets, thereby ensuring efficient power transmission. The drive component only needs to drive one drive sprocket, and multiple roller units 22 can rotate synchronously through the transmission chain. This allows all roller units 22 to convey and compress the workpiece 100 to be compressed at the same speed and rhythm, ensuring the stability and consistency of the compression operation, saving costs, and improving space utilization.

[0046] The driving components can be selected from devices such as drive motors and power pumps, which are common devices in this field. Their working principles and specific structures will not be elaborated here.

[0047] In addition, the package 100 may shift or pop out due to various unexpected situations during the pressing process. Therefore, protective nets are installed on both sides of the pressing channel 21. The protective nets can effectively block these situations and prevent the package 100 from causing accidental injury to the surrounding operators, thus providing reliable safety protection for the staff.

[0048] The outer surface of the roller unit 22 is provided with a lubricating layer, which can effectively reduce the friction between the roller unit 22 and the package 100 to be pressed. When the package 100 to be pressed moves on the roller, the smaller friction can make the conveying process smoother, reduce the risk of damage to the surface of the package 100 to be pressed due to friction, ensure the integrity of the package 100 to be pressed, and effectively reduce the occurrence of surface damage to the package 100 to be pressed.

[0049] In this embodiment, lubricating oil is used as the lubricating layer. At specified intervals, the operator applies lubricating oil to the outer surface of the roller unit 22. In other embodiments, the lubricating layer may also be a polytetrafluoroethylene coating or a graphite coating, etc., and is not limited thereto.

[0050] The pressing machine also includes a monitoring component, which can acquire the movement status of the piece to be pressed 100 in the pressing channel 21 and control the drive to run or stop based on the movement status.

[0051] Specifically, the monitoring components include an infrared sensor and a photoelectric sensor. The photoelectric sensor is located at the feed end 211. When the package 100 to be pressed enters the pressing channel 21 through the photoelectric sensor, the photoelectric sensor sends a control signal to the drive unit. The drive unit controls the roller unit 22 to rotate, thereby performing the pressing operation. The infrared sensor is located at the discharge end 212. The infrared sensor is used to monitor the number of package 100s to be pressed flowing out of the discharge end 212. When the number of package 100s to be pressed entering the feed end 211 per unit time is inconsistent with the number of package 100s to be pressed flowing out of the discharge end 212, it indicates that there may be a risk of blockage of package 100s in the pressing channel 21. At this time, the infrared sensor can control the drive unit to stop in time to avoid problems such as overload of the drive unit and damage to the transmission components caused by the roller unit 22 forcibly pushing the blocked package 100s, thus extending the service life of the equipment.

[0052] In addition, the pressing machine is also equipped with an emergency stop button. In case of other emergencies such as blockage of the package to be pressed or path deviation, the operator can press the emergency stop button to quickly stop the rotation of the drive components, so as to ensure the safety of the operator and the equipment.

[0053] It is understood that the aforementioned infrared and photoelectric sensors are common electrical devices in this field, and their working principles and specific structures will not be elaborated upon here. The signal control operations between the infrared sensors, photoelectric sensors, emergency stop buttons, and drive components in this application are centrally controlled by a programmable logic controller (PLC). It should be noted that the control logic and implementation methods of the PLC for each electrical device are conventional techniques in this field. The innovation of this application lies in the physical structure design and functional coordination of the pressing machine, rather than the programming method of the control system itself. Therefore, regarding the control details such as PLC hardware selection, program writing, and communication protocols, those skilled in the art can adapt them using known technologies according to actual needs, and will not be elaborated upon here.

[0054] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
