Description

TECHNICAL FIELD

[0001] The utility model relates to packing machine technical field, especially a comprehensive packing machine. BACKGROUND

[0002] Horizontal packing machine usually adopts horizontal direction feeding and compression mode, and loose material (such as waste paper, plastic, paperboard etc.) is compressed into regular block, and then is bound by automatic binding device with iron wire, steel band or plastic band. The horizontal hydraulic packing machine on the market can be divided into two categories: clamping arm type (without door) and door type (with door). The clamping arm type (without door) has the advantages of high packing efficiency, but the disadvantage is that the use range is small, and it can only pack some large materials. For example, the upper and lower clamping structures and systems of the clamping arm type horizontal packing machine with the authorization announcement number CN 210083737 U. Moreover, the upper and lower clamping structures occupy a large internal packing space, which affects the packing capacity and packing efficiency. The door type (with door) packing machine, such as the buffer door opening safety device and hydraulic horizontal packing machine with the authorization announcement number CN 216076782 U, has the advantages of wide use range and multiple types of packing materials, but the disadvantage is low packing efficiency. In summary, the existing packing machine has the problems of single packing mode and poor comprehensiveness, so it is necessary to develop a comprehensive packing machine. SUMMARY

[0003] In view of the deficiencies in the above background art, the utility model provides a door type double-clamping arm comprehensive packing machine, which solves the problems of single packing mode and poor comprehensiveness of the packing machine in the prior art.

[0004] The technical scheme of the utility model is implemented as follows: a door type double-clamping arm comprehensive packing machine, comprising a machine box, an inlet hopper is arranged at the upper part of the inlet area of the machine box, a rotary shaft type clamping arm compression mechanism is arranged at the left and right sides of the packing area of the machine box, and a hatch is arranged at the transverse outlet end of the machine box. The rotary shaft type clamping arm compression mechanism comprises a rotary shaft crank arm assembly arranged at the two sides of the transverse outlet and a clamping arm plate arranged at the left and right sides of the machine box. The rotary shaft crank arm assembly is arranged correspondingly with the clamping arm plate, and the rotary shaft crank arm assembly drives the clamping arm plate to perform a longitudinal clamping action in the packing area under the action of a longitudinal driving element. Through the combination of the hatch and the rotary shaft type clamping arm compression mechanism, the integration of the clamping arm type packing machine and the door type packing machine is realized, which can realize the packing of multiple materials and select the packing mode, and further improve the packing efficiency of the packing machine and the comprehensiveness of the packing machine. The rotary shaft type clamping arm compression mechanism clamps and compresses the material in the packing area from both sides in the form of rotary shaft rotation, and the stress is more uniform. At the same time, power transmission is realized by rotary shaft rotation, which reduces the transverse size of the packing area of the machine box and makes the structure more compact.

[0005] Further preferably, the longitudinal drive component is connected between two rotating shaft crank arm assemblies to enable the linkage of the two rotating shaft crank arm assemblies; the end of the clamping arm plate near the feed hopper is hinged to the machine housing via a first pin, and the longitudinal drive component drives the clamping arm plate to swing left and right around the first pin. The linkage of the rotating shaft crank arm assemblies synchronously compresses the material on both sides by swinging and pressing, improving the synchronicity of the double clamping arms. Moreover, the material near the hatch is subjected to greater force, and under the pushing action of the transverse pusher, the material forms a cone-shaped discharge, which not only facilitates discharge but also further compacts and shapes the material, improving operating efficiency.

[0006] Further preferably, the clamping arm plate includes several sub-clamping plates, the front panels of which are located in the same plane; the back of each sub-clamping plate is correspondingly arranged with the rotating shaft crank arm assembly; the rotating shaft crank arm assembly drives all sub-clamping plates to perform lateral compression simultaneously, ensuring that the material in the packaging area can be fully compressed from both sides, thereby improving the compression molding efficiency.

[0007] Further preferably, the left and right sides of the chassis are provided with several parallel crossbeams. The sub-clamps include a front panel and two rear support plates. The two rear support plates are fixed to the back of the front panel to form a U-shaped structure. The crossbeams are located between the two rear support plates. The crossbeams serve to support and guide. A gap is left between the front panels of two adjacent sub-clamps to form a cable passage groove, which facilitates the passage of the rope.

[0008] Further preferably, the rotating shaft and crank arm assembly includes a vertically arranged rotating shaft and several crank arms arranged axially on the rotating shaft. The rotating shaft is rotatably positioned on the left and right sides of the transverse outlet of the machine housing. An arm plate is fixedly mounted on the upper part of the rotating shaft. The longitudinal driving component is a telescopic hydraulic cylinder, with both ends of the telescopic hydraulic cylinder hinged to the arm plate. The crank arms are correspondingly arranged with the sub-clamping plates. The telescopic hydraulic cylinder extends and retracts, synchronously driving the two rotating shafts to rotate through the arm plates. During the rotation of the rotating shaft, the crank arms synchronously drive the clamping arm plates to move left and right relative to the machine housing, performing bilateral synchronous compression of the material inside the machine housing, thereby improving the compression molding efficiency.

[0009] Further preferably, the chassis has a door frame at the lateral outlet, the door slides in conjunction with the door frame, and the door moves up and down relative to the door frame under the action of the lifting drive to control the opening and closing of the chassis's lateral outlet; the pivot arm assembly is located on the outside of the door frame to avoid interference.

[0010] In a further preferred embodiment, the hatch includes a front panel and a rear groove plate fixed to the back of the front panel. Vertical limiting grooves are provided on both sides of the hatch frame, and the two sides of the front panel are located in the vertical limiting grooves. Several parallel wire-passing grooves are provided on the rear groove plate, and the wire-passing grooves are corresponding to the wire-passing grooves provided on the chassis; this facilitates the smooth passage of the binding rope and improves the binding efficiency.

[0011] Further preferably, the lifting drive component includes second telescopic cylinders disposed on the left and right sides of the door frame, with the telescopic rods of the second telescopic cylinders hinged to the front panel; a pivot arm assembly is located between the corresponding second telescopic cylinder and the door frame. Under the action of the second telescopic cylinders, the door moves up and down, thereby opening and closing the machine's discharge port.

[0012] Further preferably, the machine casing is equipped with a transverse pusher; the transverse pusher includes a transverse main hydraulic cylinder, and the telescopic end of the transverse main hydraulic cylinder is equipped with a push plate that matches the machine casing. The transverse pusher is used to push and compress the material inside the machine casing toward the discharge port. The transverse main hydraulic cylinder is arranged transversely, pushing the push plate to move back and forth.

[0013] Further preferred, the side wall of the chassis is provided with a rope hook unit module corresponding to the packaging area; the rope hook unit module includes a box-shaped frame, which is detachably connected to the chassis. The box-shaped frame is provided with a longitudinal sliding frame, and a number of rope hooks are provided on the longitudinal sliding frame. The rope hooks are correspondingly arranged with the cable trays provided on the chassis. The longitudinal sliding frame drives the rope hooks to move relative to the chassis under the action of the longitudinal telescopic drive component.

[0014] The beneficial effects of this utility model are as follows: This utility model integrates a door and a rotary clamping arm pressing mechanism that extrudes and forms materials from both sides, realizing the combination of a clamping arm type baler and a door type baler. One machine can select different baling modes according to different types and quantities of materials, making it suitable for the compression and baling of various materials, saving costs and increasing baling efficiency. In the door baling mode, the door is closed, the clamping arm plates are retracted, and the clamping arm plates and door cooperate with the machine box to form a box-like structure in the baling area of ​​the machine box; this mode is suitable for baling small quantities of small and loose materials for non-continuous baling operations. In the clamping arm baling mode, the door is open, and the rotary clamping arm pressing mechanisms on both sides perform simultaneous compression and forming on both sides; this mode is suitable for baling large quantities of large materials such as cartons for continuous baling operations. The two baling modes can be quickly switched, improving the applicability and versatility of the device.

[0015] This utility model's rotary clamping arm pressing mechanism uses its clamping arm plates to perform oscillating double-sided compression on the material in the packaging area, forming a conical material stack for easy discharge. Simultaneously, under the action of a transverse pusher, the conical material stack is pushed laterally to further compact the material, improving the forming rate. Multiple sub-clamping plates act simultaneously on the material in the packaging area, ensuring more even force distribution, guaranteeing forming quality, and further improving packaging efficiency. The rotary clamping arm pressing mechanism adopts a rotary shaft + crank arm design and is integrated with the hatch, reducing the number of components in the packaging area, decreasing the transverse dimensions of the packaging area, resulting in a more compact structure and more flexible power drive.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, such as Figure 1 As shown, a double-clamping arm integrated baling machine with a door includes a chassis 1. In this embodiment, a top cover plate is provided on the upper part of the chassis, and the top cover plate is sealed to the feeding hopper. Welding can be used to improve the overall sealing performance. A feeding hopper 2 is provided on the upper part of the feeding area of ​​the chassis 1. The material enters the chassis from above through the feeding hopper, and is then pushed to the baling area by a horizontal pusher. Rotary shaft clamping arm pressing mechanisms 3 are provided on the left and right sides of the baling area of ​​the chassis 1. The rotary shaft clamping arm pressing mechanisms 3 act on the left and right sides of the baling area; the rotary shaft clamping arm pressing mechanisms 3 are used to squeeze and press the material in the baling area from both sides to ensure rapid binding and baling after compaction. A hatch 4 is provided at the horizontal outlet end of the chassis 1; the opening and closing of the horizontal outlet end is achieved by opening and closing the hatch. In clamping arm baling mode, the hatch is open for continuous baling of large quantities of material, ensuring baling efficiency. In the door-operated packing mode, the door is closed, creating a relatively enclosed box-like space. Materials can range from small, loose items like shredded paper and cans to larger items like cardboard boxes. This mode is primarily designed for situations with smaller quantities of material. It involves non-continuous packing operations, using a rotating clamping arm mechanism to simultaneously compress and shape the material from both sides, ensuring packing quality. A single machine can select different packing modes based on the type and quantity of material, making it suitable for packing various materials and saving costs.

[0028] like Figure 2As shown, in this embodiment, the pivot-type clamping arm clamping mechanism 3 includes pivot-type crank arm assemblies 31 disposed on both sides of the transverse outlet and clamping arm plates 32 disposed on the left and right sides of the chassis 1. The clamping arm plates 32 are configured to cooperate with the side walls of the chassis, and the clamping arm plates almost cover the side of the chassis, ensuring simultaneous clamping and compression of the entire side of the packaging area. The pivot-type crank arm assemblies 31 are disposed on both sides of the transverse outlet and integrated with the hatch, reducing the number of components in the chassis packaging area, reducing the transverse size of the chassis packaging area, and making the structure more compact. In this embodiment, the pivot-type crank arm assemblies 31 and the clamping arm plates 32 are correspondingly configured for power transmission. Under the action of the longitudinal drive member 33, the pivot-type crank arm assemblies 31 drive the clamping arm plates 32 to perform longitudinal clamping actions in the packaging area. The longitudinal drive member provides rotational power to the pivot-type crank arm assemblies 31, and the power is transmitted to the clamping arm plates, causing the clamping arm plates to perform clamping actions. As shown in the figure, the Y direction represents the transverse direction, the X direction represents the longitudinal direction, and the Z direction represents the vertical direction. The longitudinal drive member 33 provides the force required for the clamping action of the corresponding clamping arm plates. In this embodiment, the left and right side clamping arms and the door 4 cooperate with the chassis to form a box-like structure in the packaging area of ​​the chassis 1. In the door-mounted packaging mode, the door is closed and the clamping arms retract close to the side wall of the chassis. This mode is suitable for packaging small quantities of small and loose materials, but it can also be used for large materials. It is mainly for small quantities of materials and non-continuous packaging operations, that is, packaging operations are only started when needed, saving costs. After the strapping is completed, the door is opened and the material is pushed out of the chassis by a long distance under the action of the horizontal pusher. In the clamping arm packaging mode, the door is opened and the clamping arm clamping mechanism performs double-sided compaction and shaping. This mode is suitable for packaging large quantities of large materials such as cartons and performing continuous packaging operations. This mode is mainly for working conditions with large quantities of materials. In this mode, the door is always open and there is no need to open or close the door. The clamping arm clamping mechanism and the horizontal pusher perform continuous compaction and shaping, and the strapping is tied. During this process, the material is fed out while the horizontal pusher at the rear performs short-distance pushing to ensure the continuity of the packaging work. By offering different packaging modes, the applicability and versatility of the device are improved, and rapid prototyping and packaging are achieved, thus enhancing the device's applicability and packaging efficiency.

[0029] Example 2, as Figure 3As shown, a double-clamping arm integrated baler with a door is further optimized based on embodiment 1. In this embodiment, the longitudinal drive component 33 is connected between two rotating shaft crank arm assemblies 31 to realize the linkage of the two rotating shaft crank arm assemblies 31, ensuring that the clamping arm plates on both sides perform clamping and compression actions simultaneously. The end of the clamping arm plate 32 near the feed hopper 2 is hinged to the machine housing 1 through the first pin 34. The longitudinal drive component 33 drives the clamping arm plate 32 to swing left and right around the first pin 34. The other end of the clamping arm plate is set corresponding to the door. When not clamped, the clamping arm plate contacts the door or leaves a small gap to prevent material overflow; during the clamping process, the clamping arm plate and the door will not interfere. During operation, the clamping arm plate applies a larger force to the material near the door area, while the material near the feed hopper area is subjected to a relatively smaller force. In this way, the material pile pressed out by the clamping arm plates on both sides is conical. Under the pushing action of the transverse pusher, the material forms a conical discharge, which not only facilitates discharge but also further compacts the material in the transverse direction, improving the material forming rate.

[0030] In this embodiment, the clamping arm plate 32 includes several sub-clamping plates 35, the front panels of which are located in the same plane. The number of sub-clamping plates is selected based on the height of the chassis side wall and the width of the clamping plates themselves, ensuring that they almost cover the chassis side wall to ensure that the material in the packaging area is fully compressed from both sides. The back of each sub-clamping plate 35 is correspondingly arranged with the rotating shaft crank arm assembly 31. Under the action of the longitudinal drive member 33, the rotating shaft crank arm assembly 31 simultaneously drives all the sub-clamping plates to perform clamping actions, so that the material is subjected to uniform force. It should be noted that in this embodiment, the rotating shaft crank arm assembly 31 pushes the sub-clamping plates to perform clamping and compression actions by contact pushing. The front panels of the several sub-clamping plates 35 are located in the same plane to perform planar contact compression of the material, ensuring the quality of compression and packaging.

[0031] As a specific optimization solution, such as Figure 4 As shown, the left and right sides of the chassis 1 are provided with several parallel crossbeams 12. The crossbeams create a hollow structure on the left and right sides of the chassis for the installation and movement of the sub-clamps. Each sub-clamp 35 includes a front panel 3501 and two rear support plates 3502. The two rear support plates 3502 are fixed to the back of the front panel 3501 to form a U-shaped structure. The rear support plates can be welded to the back of the front panel. The front panel is made of a smooth material to reduce friction and facilitate the passage of packaged materials. The crossbeams 12 are located between the two rear support plates 3502; the crossbeams provide support and guidance, allowing the sub-clamps to move smoothly longitudinally. A gap is left between the front panels 3501 of adjacent sub-clamps 35 to form a wire passage groove 11. The wire passage groove facilitates the passage and exit of binding ropes, making binding and knotting easier.

[0032] As a specific optimization solution, such as Figure 5 , 6As shown, the pivot arm assembly 31 includes a vertically arranged pivot 3101 and a plurality of pivot arms 3102 arranged axially on the pivot 3101. The pivot 3101 is rotatably arranged on the left and right sides of the transverse outlet of the housing 1 via bearing components. An arm plate 37 is fixedly provided on the upper part of the pivot 3101. The pivot drives the arm plate to rotate synchronously under the action of the longitudinal drive component. As a preferred embodiment, the longitudinal drive component 33 is a telescopic hydraulic cylinder. The two ends of the telescopic hydraulic cylinder are respectively hinged to the arm plates 37 on the two pivots to transmit power from the telescopic hydraulic cylinder to the pivot. It should be noted that in this embodiment, the pivot arms 3102 are correspondingly arranged with the sub-clamp plate 35. The corresponding arrangement means that the pivot arms are in contact with the sub-clamp plate but not connected when the sub-clamp plate is in its initial position. Two crank arms form a group, with the two crank arms in the same group corresponding to the two rear support plates at the same height. During the compression action, the telescopic cylinder extends, driving the rotating shaft and crank arms to rotate in the forward direction. The crank arms contact and press against the rear support plates, pushing the clamping arm plates towards the inside of the machine casing to compress the material in the packaging area. After compaction and packaging, the telescopic cylinder retracts, driving the rotating shaft and crank arms to rotate in the reverse direction, and the crank arms disengage from the rear support plates. During the process of the transverse pusher pushing the material, the pusher plate of the transverse pusher pushes the clamping arm plates back to their original position. The longitudinal drive component can also be a cylinder, and the drive component that provides the left and right swinging power for the clamping arm plates belongs to the same inventive concept as the telescopic cylinder of this utility model.

[0033] Example 3, as Figure 7 As shown, a double-clamping arm integrated baling machine with a door is further optimized based on embodiment 1 or 2. In this embodiment, a door frame 6 is provided at the transverse outlet of the machine housing 1, and the door frame is welded and fixed to the machine housing. The door 4 slides in conjunction with the door frame 6 to ensure smooth opening and closing. Under the action of the lifting drive component 7, the door 4 moves up and down relative to the door frame 6 to control the opening and closing of the transverse outlet of the machine housing 1; the pivot arm assembly 31 is set on the outside of the door frame 6, and the door frame provides support for the pivot. In this embodiment, the door adopts an up-and-down opening and closing structure. When the door is normally open, this mode is the clamping arm baling mode; when the door is closed, it cooperates with the clamping arm pressing mechanism to form a door-equipped baling mode; the two modes can be switched freely, the operation is convenient, and one machine combines two modes, reducing costs.

[0034] In this embodiment, the hatch 4 includes a hatch front panel 41 and a rear groove plate 42 fixed to the back of the hatch front panel 41. Vertical limiting grooves 61 are provided on both sides of the hatch frame 6. The vertical limiting grooves are used to limit the vertical movement of the hatch. The hatch front panel 41 is located in the vertical limiting grooves 61 on both sides. Several parallel wire-passing grooves 43 are provided on the rear groove plate 42. The wire-passing grooves 43 are corresponding to the wire-passing grooves 11 provided on the chassis 1. They are used for the smooth passage of the binding rope. After the material is compressed and formed, the binding rope is led out through the wire-passing groove and the wire-passing groove for easy knotting, thus completing the rapid binding of the material.

[0035] In this embodiment, the lifting drive component 7 includes second telescopic cylinders 71 disposed on the left and right sides of the hatch frame 6. The telescopic rods of the second telescopic cylinders 71 are hinged to the hatch front panel 41. The hatch front panel 41 is similar to a T-shaped plate, with its top two ends extending to form connecting lugs. The telescopic rods of the second telescopic cylinders 71 are connected to the connecting lugs via pins, thereby connecting the lifting drive component to the hatch 4. The pivot arm assembly 31 is located between the corresponding second telescopic cylinder 71 and the hatch frame 6, avoiding interference during the rotation of the pivot arm assembly 31, and improving the compactness and aesthetics of the device.

[0036] Example 4: A double-arm integrated baling machine with a door, such as... Figure 2 As shown, based on embodiments 1, 2, or 3, this embodiment further optimizes the design by providing a transverse pusher inside the casing 1. The transverse pusher includes a transverse main hydraulic cylinder 91, and the telescopic end of the transverse main hydraulic cylinder 91 is equipped with a push plate 92 that matches the casing 1. The push plate's shape matches the inner cavity of the casing 1, providing a certain sealing effect while allowing it to slide relative to the casing. It pushes and compresses the material in the feeding area towards the packaging area, simultaneously ejecting the packaged material through the transverse outlet and returning the clamping arm plate to its initial position. The casing also includes conventional components such as a hydraulic pump station 10 to ensure the normal operation of the equipment.

[0037] like Figure 8 As shown, in this embodiment, the side wall of the chassis 1 corresponding to the packaging area is provided with a rope hook unit module 8; the rope hook unit module 8 can be detachably connected to the chassis as an independent installation module, facilitating assembly and transportation. The rope hook unit module 8 includes a box-shaped frame 81, which is detachably connected to the chassis 1. The top of the box-shaped frame 81 is provided with a lifting ring for easy lifting and installation. The rope hook is a smooth rod with a pointed tip, and the pointed tip of the smooth rod has a hook groove for hooking and binding rope. The rope hooks 83 are correspondingly arranged with the wire passage slots 11 provided on the chassis 1, and the number of rope hooks 83 corresponds one-to-one with the number of wire passage slots 11. The longitudinal sliding frame 82 drives the rope hooks 83 to move relative to the chassis 1 under the action of the longitudinal telescopic drive member 84. The longitudinal telescopic drive component 84 can be an existing hydraulic cylinder or pneumatic cylinder, or it can be a structure of a motor plus a sprocket and chain. Specifically, a small sprocket is set at the front of the box-shaped frame, and a motor is set at the rear of the frame. A large sprocket is set on the motor, and a chain is set between the small sprocket and the large sprocket. The longitudinal sliding frame is connected to the chain. The movement of the chain drives the longitudinal sliding frame to move longitudinally, thus determining whether the rope hook is inserted into the machine box. When the rope hook is inserted into the machine box, it pulls the binding rope on the opposite side of the machine box to that side for easy knotting.

[0038] This utility model of a door-equipped double-clamping arm integrated baler integrates a horizontally exiting hatch with a rotating shaft clamping arm pressing mechanism that can simultaneously compact both sides. It enables free switching between clamping arm baling simulation mode and door-equipped baling mode, has good comprehensiveness, is applicable to the compression and baling of various materials, saves costs and has high forming efficiency.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
