Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a wire pushing mechanism and a full-automatic compacting packaging machine using the mechanism. Background Art

[0002] The baler, whose full name is horizontal hydraulic baler, is used to compress loose materials such as waste paper, waste plastic, and straw into block-shaped bags with high density and relatively regular shape, so as to reduce the volume of materials and facilitate transportation and storage. Balers are divided into semi-automatic balers and fully automatic balers. Semi-automatic balers only compress materials into bags, and the output bags are manually bundled. Fully automatic balers compress materials into bags and then use threading devices to mechanically bundle them. The output bags are bundled bags. For example, the "hydraulic fully automatic baler" with announcement number "CN102085928B" is such a fully automatic baler.

[0003] This fully automatic baler connects the baling wires into a semi-closed wire loop in advance in the compression zone, and the pushing mechanism gradually compresses the material input into the compression zone. After the compressed material bag reaches the specified length, the wire pushing mechanism in the threading device pushes the baling wires to the tying mechanism on the other side, and the baling wires on the material removal side are integrated with the original semi-closed wire loop to tie the material bag together, and the baling wires on the material input side are reconnected to form a new semi-closed wire loop to continue the subsequent material bag compression. However, it was found during use that the compression of the material bag in this fully automatic baler mainly relies on the resistance of the previously compressed material bag and the retardation of the connected semi-closed wire loop to form a blockage in the compression direction. The blocking force is limited, so the density of the material bag finally compressed is poor.

[0004] For this purpose, the inventor adopted the fully automatic packaging machine of the publication number "CN112193495B" "a fully automatic packaging machine and a fully automatic packaging method", such as Figure 5 As shown in the figure, the material door is used as a rigid barrier before output, so that the pushing mechanism can achieve a relatively ideal pushing force, and the final material package is dense and not easy to loosen. However, this fully automatic baler also has shortcomings in use, specifically: the distance between the threading device and the material door in the baler is the standard length of the material package to be packaged; the pushing mechanism pushes the material input each time toward the material door, such as Figure 6 As shown in the figure, as the amount of material near the material gate increases, the extrusion pressure near the material gate will gradually increase. Within the range of the pushing mechanism, the material near the material gate can eventually reach the specified extrusion pressure, such as Figure 7 As shown, at this time, the material density reaches the specified requirement; however, the amount of material input each time is not easy to control, so the length of the material bag that reaches the density between the pushing mechanism and the material door will be longer than the above standard length. At this time, the wire pushing mechanism in the threading device needs to push the bundle wire in this very dense material bag, such as Figure 8As shown in the figure, the wire pushing resistance is very large, and sometimes the wire pushing action cannot be completed because some materials are pushed up during the pushing process. For this reason, this kind of fully automatic baler needs to be further improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a wire pushing mechanism which reduces wire pushing resistance, facilitates smooth bundling and is convenient for modification and use on an existing baler, and a fully automatic compacting baler using the mechanism.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a wire pushing mechanism includes a wire pushing rod, two symmetrically arranged wire pushing pulleys are rotatably installed on the front end of the wire pushing rod, and a wire cutting avoidance groove is provided on the front end of the wire pushing rod between the two wire cutting avoidance grooves; a material removing shaft is rotatably installed on the wire pushing rod at the bottom of the wire cutting avoidance groove, and a material removing assembly is fixedly installed on the material removing shaft which is higher than and / or lower than the wire cutting avoidance groove, the material removing shaft is respectively connected to the two wire pushing pulleys by gear transmission, and the rotation direction of the material removing shaft is opposite to that of the two wire pushing pulleys.

[0007] As a preferred technical solution, the material tapping assembly includes a material tapping disc fixedly mounted on the material tapping shaft, and a plurality of evenly arranged material tapping teeth are fixedly provided on the outer peripheral surface of the material tapping disc.

[0008] As a preferred technical solution, the material-selecting teeth are arranged obliquely from the tooth root to the tooth end in a gradually lagging manner along the rotation direction.

[0009] As a preferred technical solution, the material-diverting disc is arranged to protrude forward from the front end surface of the thread-pushing rod.

[0010] As a preferred technical solution, the width of the material-moving assembly is not greater than the width of the front end of the wire-pushing rod.

[0011] The fully automatic dense baling machine using the wire pushing mechanism comprises a machine body, the machine body is provided with a baling channel which is arranged transversely through the machine body, the machine body is provided with a pushing mechanism at one end of the baling channel, and the machine body is provided with a material gate at the other end of the baling channel; the baling channel comprises a feeding section close to the pushing mechanism and a baling section close to the material gate, the top wall of the feeding section is provided with a feeding port, the machine body is provided with a wire pushing bracket and a bundling bracket on both sides of the baling section, a wire pushing slide is installed on the wire pushing bracket, and a plurality of the wire pushing mechanisms which are arranged in sequence up and down are installed on the wire pushing slide; a wire pushing driver is provided between the wire pushing slide and the wire pushing bracket; and the bundling bracket is provided with a wire cutting mechanism and a bundling mechanism which correspond to the wire pushing mechanisms one by one.

[0012] Due to the adoption of the above technical solution, when pushing the wire, the utility model utilizes the rotation of the two wire pushing pulleys after being pulled by the bundle wire to drive the material diverting shaft to rotate, and the material diverting assembly can produce the effect of diverting the material during the wire pushing process, which is conducive to reducing the material blocking, avoiding pushing the material, reducing the wire pushing resistance, and facilitating smooth bundling. The wire pushing mechanism of the utility model has a simple structure and is convenient for direct modification and use on the existing baler. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the wire pushing mechanism 21 includes a wire pushing rod 4, which is a direct structure for pushing the bundle wire 91 through the material. Two symmetrically arranged wire pushing pulleys 41 are rotatably mounted on the front end of the wire pushing rod 4, and a wire cutting avoidance groove 42 is provided on the front end of the wire pushing rod 4 between the two wire pushing pulleys 41. When pushing the wire, the bundle wire 91 at the packaged material bag 9 is basically kept stationary due to extrusion and other reasons, so the wire pushing process is equivalent to extracting the bundle wire 91 from the bundle wire supply device for use, and the bundle wire 91 at the wire pushing pulley 41 moves tangentially at the wheel surface of the wire pushing pulley 41, thereby the rotatability of the wire pushing pulley 41 can avoid the occurrence of jamming during the process of extracting the bundle wire 91, which is conducive to smooth wire pushing; on the contrary, the bundle wire 91 will also drive the wire pushing pulley 41 to rotate.

[0025] A material shifting shaft 5 is rotatably mounted on the thread pushing rod 4 at the bottom of the thread trimming avoidance groove 42, and a material shifting assembly 6 is fixedly mounted on the material shifting shaft 5 which is higher and / or lower than the thread trimming avoidance groove 42. The material shifting assembly 6 is used to shift materials during the thread pushing process, and the material shifting assembly 6 can be set to one or two; when set to one, it can be above or below the thread trimming avoidance groove 42; when set to two, they are respectively above and below the thread trimming avoidance groove 42. The latter is illustrated in this embodiment.

[0026] The material-pickup shaft 5 is connected to the two wire-pushing pulleys 41 by gear transmission, and the rotation direction of the material-pickup shaft 5 is opposite to that of the two wire-pushing pulleys 41. In the wire-pushing process, from a top-down perspective, the bundled wire 91 drives the two wire-pushing pulleys 41 to rotate counterclockwise, so the material-pickup assembly 6 rotates clockwise. Since the front side of the material-pickup assembly 6 mainly plays a material-pickup role, it is equivalent to prying the material away from the packed material bag 9. The material thickness in this direction is still small, and it is easier to pry.

[0027] Preferably, means for increasing friction can be added to the wheel surface of the wire pushing pulley 41, such as increasing the roughness of the wheel surface, setting concave and convex grooves on the wheel surface, etc., so that the wire bundle 91 can better drive the wire pushing pulley 41 to rotate during the wire pushing process, thereby providing better material shifting drive.

[0028] The material-digging assembly 6 of this embodiment includes a material-digging disc 61 fixedly mounted on the material-digging shaft 5, and a plurality of evenly arranged material-digging teeth 62 are fixedly disposed on the outer circumference of the material-digging disc 61. Preferably, the material-digging teeth 62 are arranged obliquely from the tooth root to the tooth end in a gradually lagging manner along the rotation direction. With this shape setting, the material-digging teeth 62 are not prone to forcibly hooking and pulling the material, but mainly realize material digging in a kneading manner, which is conducive to reducing material jamming.

[0029] Preferably, the width of the material-digging component 6 is not greater than the width of the front end of the wire-pushing rod 4, which makes it difficult for the material-digging component 6 to dig the materials on the left and right sides of the wire-pushing direction of the wire-pushing rod 4, further helping to reduce the jamming of materials. Preferably, the material-digging plate 61 is arranged to protrude forward from the front end face of the wire-pushing rod 4, which helps to prevent the materials from entering between the material-digging teeth 62 and the wire-pushing pulley 41, further helping to reduce the jamming of materials. Among them, the width of the front end of the wire-pushing rod 4 is the maximum width of the part where the two wire-pushing pulleys 41 are installed, and the front end face of the wire-pushing rod 4 is a virtual surface formed by the frontmost side of the part where the two wire-pushing pulleys 41 are installed.

[0030] like Figure 4 As shown, the fully automatic dense baler using the pushing wire mechanism 21 includes a body 1, and the body 1 is provided with a baling channel 11 that is arranged transversely through the body 1. The body 1 is provided with a pushing mechanism 12 at one end of the baling channel 11. Conventionally, the pushing mechanism 12 includes a pushing plate and a pushing drive cylinder. A material gate 13 is provided at the other end of the baling channel 11 on the body 1. Conventionally, the material gate 13 can be raised and lowered, and is driven by a lifting drive cylinder to open and close. The baling channel 11 includes a feeding section 111 close to the pushing mechanism 12 and a baling section 112 close to the material gate 13. A feeding port 14 is provided on the top wall of the feeding section 111. The pushing mechanism 12 pushes the material entering the feeding section 111 from the feeding port 14 toward the material gate 13, and finally squeezes the material near the material gate 13 to form a material bag 9.

[0031] The body 1 is provided with a wire pushing bracket 2 and a bundling bracket 3 on both sides of the bagging section 112, respectively; the wire pushing bracket 2 is provided with a wire pushing slide, and the wire pushing slide is provided with a plurality of wire pushing mechanisms 21 arranged in sequence up and down; a wire pushing driver is provided between the wire pushing slide and the wire pushing bracket 2; the bundling bracket 3 is provided with a wire cutting mechanism 31 and a bundling mechanism 32 corresponding to the wire pushing mechanism 21 one by one.

[0032] Conventionally, the distance between the pusher mechanism 21 and the material gate 13 is the standard length of the material bag 9 to be packaged. After the last push of the pusher mechanism 12, the pressure at the bagging section 112 reaches the specified pressure, and the density of the material bag 9 reaches the specified requirement, such as Figure 4 As shown, the length of the material block formed by pushing is greater than the above-mentioned standard length of the material bag 9. After that, the pushing mechanism 12 first retreats to release the pushing force, and then the wire pushing driver pushes the wire pushing slide to slide toward the bundling bracket 3, and the front end of the wire pushing rod 4 penetrates the material block and pushes the bundle wire 91 at the same time during the penetration process. In this pushing process, Figure 1 and Figure 3 As shown, the binding wire 91 drives the wire pushing pulley 41 to rotate forcedly, and the forced rotation drives the material shifting assembly 6 to shift a small portion of the material on the incoming material side away from the material bag 9, which helps to alleviate material obstruction, avoid squeezing the material, reduce wire pushing resistance, and facilitate smooth bundling.

[0033] After the front end of the wire pushing rod 4 passes through the material block, it will simultaneously drive the binding wire 91 on the other side to the opposite bundling bracket 3, and the wire cutting mechanism 31 on the bundling bracket 3 will cut the two binding wires 91, and a group of free ends of the binding wires 91 will be formed on both sides of the wire cutting mechanism 31, and the bundling mechanism 32 on the bundling bracket 3 will wind and bundle the free ends of the two binding wires 91 on the corresponding side. Finally, a closed-loop bundling coil is formed on the unloading side of the bundling bracket 3, which bundles a material bag 9 of standard length, and a semi-closed wire loop is formed on the incoming side of the bundling bracket 3. The wire pushing rod 4 is retracted, and the retraction process does not involve the pulling of the binding wire 91, so the wire pushing pulley 41 and the material shifting assembly 6 will not rotate, and since the retraction channel is a channel that has been penetrated and opened, the material shifting assembly 6 is not easy to be hooked with the material, and the retraction is smooth.

[0034] The material door 13 is opened, and the pushing mechanism 12 continues to push the newly input material. Under this pushing, the bundled material bag 9 extends out of the bagging channel 11 and is pulled out by other devices. After being pulled out, the material door 13 is closed, and the pushing mechanism 12 pushes the input batches of materials back and forth until the bagging section 112 reaches the specified pressure again, that is, another new material bag 9 is pushed, and the above-mentioned bundling action is repeated to form a fully automatic dense packaging operation.

[0035] The arrangement of the material-pickup assembly 6 in this embodiment above and below the wire-cutting avoidance groove 42 can avoid interference with the wire-cutting mechanism 31. The structural principles of the wire-pushing driver, the wire-cutting mechanism 31 and the bundling mechanism 32 are well-known in the art and will not be described in detail herein and are not shown in the drawings.

[0036] In this embodiment, the wire pushing pulley 41 is rotated by the wire 91 during the wire pushing process, driving the material-moving shaft 5 to rotate, thereby producing the effect of moving the material, which helps to reduce the material blocking, avoid pushing the material, reduce the wire pushing resistance, and facilitate smooth bundling. The wire pushing mechanism 21 has a simple structure, and is mainly equipped with the material-moving shaft 5 and the material-moving assembly 6 compared to the existing wire pushing mechanism 21, so it is convenient to directly modify and use it on the existing baler.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
