Description

Technical Field

[0001] The present invention relates to an apparatus and a packing method for automatically packing and briquetting rubber, in particular to an apparatus that first automatically feeds rubber, then automatically packs it, and finally automatically discharges a standard finished rubber bale, that is, a granular rubber hydraulic packing machine, belonging to the technical field of automation equipment. Background Art

[0002] With the continuous progress of technology, rubber, as the core raw material for automobile tire production, occupies a large share in the industrial field. In recent years, scientific research scholars have increasingly in-depth research on rubber, and the uses of rubber are also developing in a diversified direction. It can be said that rubber covers almost all aspects of people's daily lives. In recent years, the annual consumption of rubber has been on the rise year by year, and the number of rubber-related manufacturers has also been gradually increasing. The production of rubber has gradually developed towards the direction of intelligence, high efficiency and automation.

[0003] The primary processing of rubber is a process of making standard rubber bales by chemically and physically treating natural rubber-containing substances. First, natural latex is collected, then coagulated by adding acid, and the rubber blocks are cleaned by using relevant cleaning equipment. Subsequently, the rubber blocks are extruded and mashed into granular form by some equipment and then washed repeatedly. Finally, a multi-stage creping process is carried out. After creping, the rubber is crushed into granular form by a rubber shredder and then dried. Workers weigh the dried rubber according to national standards and place the rubber with the same weight but fluffy texture and uneven size into a packing machine for extrusion and packing. Finally, standard rubber bales with uniform size, quality and shape are formed and supplied to the downstream of the industry. Among them, the packing link is one of the key technological links in the production process of standard rubber. This technological link requires compacting the weighed rubber blocks (masses) with fluffy texture, oversized volume and irregular shape into standard rubber bales of unified specifications, so as to make the size of the rubber bales unified, reduce the volume, and facilitate transportation, stacking, storage and trading. In the field of primary rubber processing, there are currently two packing links. One is the packing of rectangular rubber blocks after drying, and the other is the packing of irregular rubber masses after dry mixing and kneading. The current degree of automation in the packing link is very low, and a large amount of manual assistance is required. First, the weighed rubber blocks (masses) need to be manually carried into the packing box for packing. This traditional packing technology belongs to a semi-automatic operation mode. Generally, 2-3 people are required to carry and pack the material bales on one packing line (equipped with 2-3 packing machines). Due to differences in production organization models of each company, generally 3-6 people are required for auxiliary work in this process section. Moreover, the current production mode of rubber processing factories is generally two-shift system, that is, 6-12 people are required for assistance to complete the rubber packing process. The labor intensity of the work is huge. When discharging the finished rubber, it is mainly grabbed by a bale nail, and there are often situations where the grabbing is unstable or unsuccessful. There are great safety hazards during manual discharging.

[0004] Generally speaking, the basic working process of the current packing machine is as follows:

[0005] (1) Feeding stage: The dry rubber blocks of standard weight are manually placed into the hopper from the weighing table.

[0006] (2) Packing stage: When the pushing cylinder pushes the right hopper to move under the pressing block, the main cylinder pushes the pressing block downward to a fixed position. The pressing block and the material box form a sealed space, extruding the rubber blocks for a certain period of time to complete the packing. At the same time, the bag-lifting nails installed under the pressing block are embedded into the rubber package.

[0007] (3) Chamber discharging stage: After the packing is formed, when the pressing block is lifted, the rubber package is lifted at the same time. The pushing cylinder returns and drives the hopper to move to the middle position. After the rubber package drops, it slides out from the middle roller track.

[0008] (4) Circulation stage: The pushing cylinder returns and drives the left hopper to move under the pressing block to continue packing, forming a working mode of alternating cyclic packing of the left and right hoppers.

[0009] Through such a working process, it is basically possible to extrude and pack the dry rubber packages into standard rubbers of a certain size.

[0010] However, there are the following problems with the current method:

[0011] ① Manual feeding. During operation, it is necessary to manually carry the rubber blocks (masses) and put them into the hopper of the packing machine, with a relatively high labor intensity. On average, each person needs to carry 12.5 tons of rubber per day.

[0012] ② Difficult bag lifting and box discharging. When lifting the bag, it is mainly through the bag-lifting nails under the pressing block. Due to the large friction between the rubber package and the inner wall of the hopper, the friction between the bag-lifting nails and the rubber package will decrease as the bag-lifting nails wear. There are often situations where the bag-lifting nails cannot lift the rubber package, that is, the bag jamming phenomenon. Once it occurs, it must be taken out manually, which is time-consuming and laborious and not easy to operate due to environmental restrictions, and there are safety hazards.

[0013] ③ Generation of process holes. Through the grasping of the bag-lifting nails, process holes will be left on the standard rubber, affecting the appearance quality and also being unfavorable to the uniformity of subsequent rubber cutting and feeding.

[0014] Therefore, aiming at the current problems of time-consuming, laborious, high safety hazards, high labor intensity and low automation degree encountered by current rubber processing enterprises in the packing link, developing a convenient, safe and highly automated rubber automatic packing system is the key point that current rubber production and processing enterprises urgently need to solve. Summary of the Invention

[0015] In view of the aforementioned current requirements and problems to be solved in the process of automatic rubber packing, the purpose of the present invention is to solve the problems existing in the current automatic rubber packing process, such as high safety hazards, low automation level, large labor intensity, and irregular package shape. It uses intelligent technical means to replace manual production, liberate the labor force, improve the appearance quality, overall efficiency and automation level of standard rubber packages, so that the standard rubber packages after automatic production meet the goals of standardization, high efficiency, speed and uniformity, and increase the automatic production capacity of rubber standard packages.

[0016] A granular rubber hydraulic packing machine and a packing method of the present invention can complete the processes of automatically feeding, automatically packing and automatically discharging the weighed rubber material, and finally form standard rubber packages with uniform size, appearance, etc. It completes the automatic rubber packing process and solves the problems of low automation level, large labor intensity of workers and high safety hazards in current rubber processing factories. It can effectively improve the automation and intelligent level of rubber processing.

[0017] According to the first aspect, the technical solution of the present invention is as follows:

[0018] A granular rubber hydraulic packing machine can realize the technological processes of automatically feeding and discharging rubber and automatically packing rubber in the process of automatic rubber production, and the whole system operates fully automatically. The packing machine includes: a feeding hopper, a sealing plate mechanism, a universal ball, a discharging roller, a frame, a movable ladder, a support panel, a packing box mechanism, an upper top plate, a connecting pillar, a hydraulic system and a pushing mechanism. Among them:

[0019] The frame is the main support frame of the baling machine of the present invention; the support panel is fixed above the frame, and the support panel is the main bearing platform of the baling machine of the present invention; the support panel and the upper top plate are connected into one body through connecting struts, and the upper top plate is the feeding and discharging platform of the baling machine of the present invention. The feeding hopper is fixed on the upper top plate and is mainly responsible for receiving the rubber material to be baled; the pushing mechanism is arranged on the upper top plate, and the completed baled finished rubber bales can be automatically pushed out through the reciprocating movement of the pushing plate; universal balls are arranged at the discharging port of the upper top plate to reduce the friction between the rubber and the upper top plate, so that the energy consumption can be reduced when the pushing plate pushes out the finished rubber blocks; the packing box mechanism is arranged on the support panel, and the packing and compressing process of the rubber is carried out in the packing box. The inner cavity size of the packing box determines the outer shape size of the finished standard rubber bales; the sealing plate mechanism is arranged between the upper top plate and the packing box. The sealing plate mechanism is mainly responsible for opening and closing the feeding and discharging ports of the upper top plate and the packing box. When it is opened, the rubber material can enter and exit. When it is closed, the rubber material can be packed and compressed; the discharging roller is fixed on the support panel. The discharging roller is an inclined non-powered roller table structure, and its front section is placed below the universal balls at the discharging port of the upper top plate. It is mainly responsible for receiving the finished standard rubber after packing and buffering and transporting the standard rubber to the next process section. The discharging roller belongs to the finished product material outlet of the baling machine of the present invention; the mobile ladder is arranged on the left and right sides of the frame, and maintenance workers can climb onto the support panel through the mobile ladder to install, repair, maintain, etc. the equipment; the hydraulic system is independently arranged behind the frame, and the hydraulic system can realize the actions of receiving, packing and discharging the rubber.

[0020] Further, the feeding hopper is an inverted cone structure with a large inlet and a small outlet. The upper opening is larger than the outlet size of the conveying channel of the upper-level process, which is convenient for receiving the rubber scraps conveyed by the upper-level process and preventing rubber leakage. The lower opening is smaller than the inner cavity size of the packing box, which is convenient for the rubber scraps to enter the packing box without omission;

[0021] Further, the sealing plate mechanism is a vertically floating linear telescopic mechanism, which is composed of a sealing plate, a cylinder, a rotating hinge, a fixed hinge, universal ball bearings, and a guide rail. Among them, universal ball bearings are arranged on the side wall surface of the sealing plate. The cylinder is fixed on the other side wall surface of the sealing plate through a rotating hinge, the other end of the cylinder is fixed through a fixed hinge, and the guide rail is fixed below the upper top plate. The sealing plate can use the universal ball bearings as the contact carrier and perform linear motion on the guide rail through the driving action of the cylinder. At the same time, under the combined action of the rotating hinge and the fixed hinge, the sealing plate can also perform a certain vertical lifting motion during the linear motion. That is, in the sealing plate mechanism, the sealing plate can realize linear motion in both the left-right and up-down directions.

[0022] Furthermore, the packing box mechanism is a scissor-type micro-motion lifting mechanism controlled by a cam, which is composed of a packing box, a connecting shaft, a stroke cam, a cam bearing, a driving motor, a motor bracket, a fixed bearing, a scissor shaft, a scissor bearing, a lower sliding seat, a roller and an upper sliding seat. There are two groups of lower sliding seats, which are support bases. A fixed bearing is arranged on one side of the lower sliding seat, and the fixed bearings are connected through a connecting shaft. The other lower sliding rail serves as a sliding track. A total of four scissor shafts are arranged, paired in twos, and connected and fixed at the central position through scissor bearings. After connection, the scissor shafts can rotate relative to each other to realize the scissor rotation similar to scissors. One end of the scissor shaft is connected to the connecting shaft, and the scissor shaft and the connecting shaft can rotate relative to each other. A roller is arranged at the other end of the same scissor shaft. The lower roller can roll linearly on the lower sliding seat, and the upper roller can roll linearly on the upper sliding seat. The upper sliding seat is fixed on one side wall of the packing box. Fixed bearings are arranged in the front-back direction on the other side wall of the packing box, and the fixed bearings are connected through a connecting shaft. That is, one side wall surface of the packing box is fixed through a fixed bearing, and the other side wall surface is placed on the roller through the upper sliding seat, forming a structure in which the scissor shaft holds up the packing box. A cam bearing is arranged below the wall surface of the fixed bearing of the packing box. The motor bracket is fixed on the support panel, the driving motor is placed on the motor bracket, and the stroke cam is arranged on the output shaft of the driving motor. The cam bearing located on the packing box is embedded in the stroke cam to form a matching structure. Through the drive of the driving motor, the stroke cam rotates, thereby driving the cam bearing to move. Under the scissor movement of the scissor shaft, the packing box can be smoothly lifted vertically. The distance of its lifting movement is controlled by the eccentricity of the stroke cam, and accurate control of the lifting position can be achieved.

[0023] Furthermore, the hydraulic system is composed of a hydraulic cylinder, a packing push plate and a hydraulic pump station. The hydraulic pump station is the main power output of the hydraulic system and also the power source for rubber packing and discharging in the present invention. The hydraulic cylinder is fixed on the support panel. The packing push plate is fixed on the hydraulic push rod in the hydraulic cylinder, and the vertical movement of the packing push plate can be driven through the pushing action of the hydraulic push rod. The packing push plate can realize the functions of receiving materials, packing and discharging under the drive of the hydraulic system.

[0024] Further, the pusher mechanism is composed of a guide rail, a pusher plate, a driving motor, a driving sprocket, a slider, a sprocket bracket, a driven sprocket and a chain; the guide rail is fixed on the upper top plate; the slider is fixed under the pusher plate, and the pusher plate can move linearly along the guide rail through the slider; the driving motor is fixed at the end of the guide rail, and the driving sprocket is fixed on the output shaft of the driving motor; the sprocket bracket is fixed at the other end of the guide rail, and a driven sprocket with a tensioning function is fixed on the sprocket bracket; one end of the chain is fixed on the side wall of the pusher plate, and the other end is fixed on the side wall of the pusher plate after passing around the driving sprocket and the driven sprocket. Through the forward and reverse rotation drive of the driving motor, the chain can generate power under the traction of the driving sprocket and the driven sprocket, and then pull the pusher plate to make a linear reciprocating motion on the guide rail, so as to realize the pushing out of the finished standard rubber package.

[0025] Further, the packing box in the packing box mechanism has an open structure at both the upper and lower parts. When the packing box is receiving materials, the bottom opening is sealed by a packing push plate in the hydraulic system to prevent the rubber scraps from flowing out of the packing box; when the packing box is packing, the sealing plate mechanism between the packing box and the upper top plate seals both the upper opening of the packing box and the opening of the upper top plate, and the hydraulic system starts to move upward. The rubber is extruded onto the sealing bottom plate through the packing push plate to complete the packing action; when the finished product is discharged, the sealing plate mechanism opens the upper opening of the packing box, and the hydraulic system starts to move upward continuously. The finished rubber can be pushed out through the packing push plate.

[0026] Further, the sealing plate in the sealing plate mechanism has a hollow open structure. Under the action of its floating linear expansion and contraction, when packing the rubber, the sealing plate seals the openings of the packing box and the upper top plate. Under the action of the stroke cam, the packing box moves upward, and the upper surface of the sealing plate can be in contact with the upper top plate, ensuring direct contact between the packing box, the sealing plate and the upper top plate, so that the packing extrusion force generated by the hydraulic system during the packing work directly acts on the upper top plate, preventing the sealing plate from being stressed and increasing the safety of the equipment; when the rubber finished product is discharged, the sealing plate retracts, aligning the opening of the sealing plate with the upper opening of the packing box. The other structures are the same as those during packing, which can ensure that the friction force generated between the rubber and the side wall of the packing box during the discharge of the finished product is borne by the upper top plate, effectively protecting the cam structure.

[0027] Furthermore, the operation of the hydraulic baler is mainly controlled based on a PLC system. A feeding detection sensor is provided at the feeding hopper. When it detects that the material has completely entered, it controls the start and stop of the front-end feeding section and simultaneously controls the operation of the sealing plate mechanism in the hydraulic baler. A sealing plate in-place detection sensor is provided on the sealing plate mechanism to detect whether the sealing plate is in place when it extends and controls the start and stop of the packing box mechanism. A packing box in-place detection sensor is arranged above the packing box mechanism to detect whether the packing box is in place and controls the start of the hydraulic cylinder to squeeze and bale the rubber. After the bailing action is completed, it returns to the initial position. A in-place detection sensor is provided at the initial position of the packing cylinder to detect whether the bailing is completed and control the packing box and the sealing plate to return to the zero position. Detection sensors are provided at the zero positions of the two to detect whether they have returned to the zero position in place and control the pushing action of the packing cylinder to push the finished rubber bale out of the box. An in-place detection sensor is provided at the extreme position of the movement of the packing cylinder to detect whether the packing cylinder has pushed the finished rubber bale out of the box and simultaneously control the operation of the pushing mechanism to push the finished rubber bale onto the discharging conveying roller.

[0028] Furthermore, the PLC control system and each detection sensor device cooperate to control the operation of the entire system. The detection sensors at each moving component work according to the above functions. When the hydraulic baler starts to operate: after the feeding detection device detects the entry of the material, the PLC system controls the sealing plate of the sealing plate mechanism to be pushed out to seal the openings of the packing box and the upper top plate. After the sealing plate in-place detection device detects the sealing signal, the PLC control system controls the packing box to move upward. After the upward movement detection device detects the packing box in-place signal, the PLC control system immediately controls the packing cylinder to start operating to squeeze and bale the rubber in the packing box. After the squeezing and bailing are completed, the packing cylinder returns to the zero position. After the packing cylinder return-to-zero detection sensor detects the signal, the PLC control system controls the packing box and the sealing plate to return to the zero position successively. After the packing box and the sealing plate return-to-zero detection sensors detect the signals, the PLC control system controls the packing box to move upward. After the packing box upward movement detection sensor detects the signal, the PLC control system controls the packing cylinder to start operating again to the extreme position to push out the standard rubber finished product after bailing. When the detection sensor at the extreme position of the packing cylinder detects the signal, the PLC system controls the push plate to start operating to push out the finished rubber and push the finished rubber bale onto the discharging conveying roller. Then the PLC control system controls all other components in the hydraulic baler to return to the initial zero position and wait for the next bailing process.

[0029] According to the second aspect, the method for automatically baling rubber of the present invention is specifically as follows:

[0030] At the start of S1, the system begins to operate. The rubber scraps are conveyed by the conveyor belt from the previous - level process system, and the weighed rubber scraps are transported to the feed hopper of the hydraulic baler and fall into the packing box with a packing push - plate at the bottom to receive the materials.

[0031] After the rubber scraps have finished falling, the hydraulic baler starts to run. That is, the sealing - plate cylinder pushes the sealing plate to seal the feed inlet, enclosing the packing box into a sealed cavity.

[0032] The drive motor in the packing - box mechanism runs, causing the cam to move. Driven by the cam and the scissor structure, the packing box moves upward to ensure direct contact among the packing box, the sealing plate, and the upper top plate, so that the packing pressure during extrusion packing is borne by the upper top plate.

[0033] Subsequently, the hydraulic system is started, and the packing push - plate moves upward to extrude and pack the rubber scraps with the sealing plate as the supporting bottom plate. The packing pressure is borne by the upper top plate, completing the extrusion and packing work of the rubber.

[0034] When the hydraulic packing pressure reaches the rated extrusion pressure of the standard rubber bale, the packing push - plate stays at this position for a certain time to keep the pressure on the standard rubber bale, and then the packing push - plate moves downward to return to the initial zero position.

[0035] Immediately, the drive motor in the packing - box mechanism runs, causing the cam to move. Driven by the cam and the scissor structure, the packing box moves downward to return to the initial position, separating the packing box, the sealing plate, and the upper top plate from each other, leaving a gap for the sealing plate to return to zero.

[0036] The sealing - plate cylinder operates to pull back the sealing plate, making the sealing plate return to the zero position, ensuring that the opening of the sealing plate aligns with the opening of the upper top plate, leaving space for the standard rubber bale to exit the box.

[0037] The drive motor in the packing - box mechanism runs, causing the cam to move. Driven by the cam and the scissor structure, the packing box moves upward to ensure direct contact among the packing box, the sealing plate, and the upper top plate, so that the frictional force between the rubber and the packing box that the standard rubber bale needs to overcome during discharging is borne by the upper top plate, and the cam is not stressed when pushing the rubber out of the box, ensuring the safety of the equipment.

[0038] The hydraulic system is started, causing the packing push - plate to move upward to the extreme position of the hydraulic system, pushing out the finished - product standard rubber bale in the packing box.

[0039] When the hydraulic ram pushes the finished rubber bale to the extreme position, the drive motor in the pusher - plate mechanism starts. The pusher - plate moves linearly on the guide rail under the driving action of the traction chain, and during the movement, the finished - packed standard rubber bale is pushed out onto the discharge roller, completing the discharging of the finished - product rubber bale.

[0040] After the discharging at S11 is completed, the pushing plate driving motor starts in the reverse direction to return the pushing plate to the initial zero position; meanwhile, the hydraulic system starts to return the hydraulic pressure head to the initial zero position; meanwhile, the driving motor in the packing box mechanism operates to move the cam, and driven by the cam and the scissor structure, the packing box moves downward to return to the initial position, separating the packing box, the sealing plate and the upper top plate from each other, leaving a moving gap for the sealing of the sealing plate, and then the next packing work begins;

[0041] Through the above steps S1 to S11, the automatic material receiving, extrusion packing and discharging processes of the rubber are completed.

[0042] The working principle of the present invention:

When realizing automatic baling of rubber through this system, the rubber scraps are transported by the conveyor belt from the upper-level process system, and the weighed rubber scraps are transported to the feeding hopper of the hydraulic baler and fall into the packing box with a packing push plate at the bottom for receiving; after the rubber scraps have fallen, the hydraulic baler starts to run.That is, the sealing plate cylinder pushes the sealing plate to seal the feeding port, closing the packing box into a sealed cavity; the drive motor in the packing box mechanism runs to make the cam move.

Specific implementation mode

[0058] The following further describes the process of automatic rubber packing of the present invention in conjunction with the accompanying drawings.

Any modifications, equivalent replacements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0059] Embodiment 1

[0060] A granular rubber hydraulic packing machine can realize the process of automatic feeding and discharging and automatic packing of rubber during the automatic production process of rubber. The whole system operates fully automatically, solving the problems of low automation level, high labor intensity of workers, and high safety hazards in current rubber processing factories. It can effectively improve the automation and intelligent level of rubber processing.

Universal ball bearings 205 are arranged on the side wall surface of the sealing plate 201, the cylinder 202 is fixed on the other side wall surface of the sealing plate 201 through the rotating hinge 203, the other end of the cylinder 202 is fixed through the fixed hinge 204, the first guide rail 206 is fixed below the upper top plate 9, and the sealing plate 201 can use the universal ball bearings 205 as the contact carrier and perform linear motion on the first guide rail 206 under the driving action of the cylinder 202. At the same time, under the combined action of the rotating hinge 203 and the fixed hinge 204, the sealing plate 201 can also perform a certain vertical lifting motion during the horizontal linear motion. That is, in the sealing plate mechanism 2, the sealing plate 201 can realize the vertically floating and linearly telescopic motion.

[0063] As Figure 5As shown in the figure, the structure of the packing box mechanism 8 is a scissor-type micro-motion lifting mechanism controlled by a cam stroke, which is composed of a packing box 801, a connecting shaft 802, a stroke cam 803, a cam bearing 804, a first driving motor 805, a motor bracket 806, a fixed bearing 807, a scissor shaft 808, a scissor bearing 809, a lower sliding seat 810, a roller 811 and an upper sliding seat 812. There are two groups of lower sliding seats 810. A fixed bearing 807 is arranged on one side of the lower sliding seat 810, and the fixed bearings 807 are connected through a connecting shaft 802. The lower sliding seat 810 on the other side serves as a sliding track. A total of four scissor shafts 808 are arranged, paired in twos, and are connected and fixed at the central position through scissor bearings 809.

Driven by the first driving motor 805, the stroke cam 803 rotates, thereby driving the cam bearing 804 to move. Under the scissor movement of the scissor shaft 808, the packing box 801 can perform a stable vertical lifting movement, and the lifting distance of the lifting movement is controlled by the eccentricity of the stroke cam 803, and accurate control of the lifting position can be achieved.

[0064] As Figure 6 shown, the sealing plate mechanism 2 and the packing box mechanism 8 cooperate with each other to perform opening and sealing actions, that is, the sealing plate mechanism 2 is arranged above the packing box mechanism 8. When the packing box mechanism 8 moves and the packing box 801 moves upward, the packing box 801 will first contact the sealing plate 201, and continue to push the sealing plate 201 upward during the continuous upward movement until the packing box 801, the sealing plate 201 and the upper top plate 9 are in contact with each other. When the packing box 801 is at the lowest position, there are gaps between the packing box 801, the sealing plate 201 and the upper top plate 9. As shown in the appendix Figure 3 shown, at this time, the sealing plate mechanism 2 can freely expand and contract to realize the opening and closing of the opening of the packing box 801 and the upper top plate 9 by the sealing plate 201.

[0065] As Figure 8As shown in the figure, the hydraulic system 11 is composed of a hydraulic cylinder 1101, a packing push plate 1102, and a hydraulic pump station 1103. The hydraulic pump station 1103 is the power source for rubber packing and discharging in this machine; the hydraulic cylinder 1101 is fixed on the support panel 7; the packing push plate 1102 is fixed on the hydraulic push rod inside the hydraulic cylinder 1101, and the packing push plate 1102 can be driven to move vertically by the pushing action of the hydraulic push rod; the packing push plate 1102 can realize the functions of receiving materials, packing, and discharging under the drive of the hydraulic system 11.

[0066] As Figure 7 shown in the figure, the pushing mechanism 12 is composed of a second guide rail 1201, a pushing plate 1202, a second driving motor 1203, a driving sprocket 1204, a slider 1205, a sprocket support 1206, a driven sprocket 1207, and a chain 1208; the second guide rail 1201 is fixed on the upper top plate 9; the slider 1205 is fixed under the pushing plate 1202, and the pushing plate 1202 can move linearly along the second guide rail 1201 through the slider 1205; the second driving motor 1203 is fixed at the end of the second guide rail 1201, and the driving sprocket 1204 is fixed on the output shaft of the second driving motor 1203; the sprocket support 1206 is fixed at the other end of the second guide rail 1201, and a driven sprocket 1207 with a tensioning function is fixed on the sprocket support 1206; one end of the chain 1208 is fixed on the side wall of the pushing plate 1202, and the other end is fixed on the side wall of the pushing plate 1202 after passing around the driving sprocket 1204 and the driven sprocket 1207. Through the forward and reverse rotation drive of the second driving motor 1203, the chain 1208 can generate power under the traction of the driving sprocket 1204 and the driven sprocket 1207, and then pull the pushing plate 1202 to perform a linear reciprocating motion on the second guide rail 1201, so as to realize the pushing out of the finished standard rubber bales.

[0067] Regarding the sealing plate mechanism 2, the packing box mechanism 8, and the pushing plate 1202 mechanism in a granular rubber hydraulic packing machine and a packing method. Among them, the sealing plate mechanism 2 is not limited to using a cylinder 202 to push to achieve the linear expansion and contraction of the sealing plate 201, and other structures such as a gear-rack structure, a hydraulic mechanism, and an electric push rod structure can also be used to realize the linear expansion and contraction of the sealing plate 201; the micro-motion lifting of the packing box mechanism 8 is not limited to using a scissor structure. Under the condition that the processing accuracy and assembly accuracy are met, a cylinder 202 structure, an electric push rod, and other structures combined with actuating components such as a slider 1205 and a linear bearing can also be used to achieve the purpose of micro-motion lifting; the sprocket chain 1208 in the pushing plate 1202 mechanism can also be replaced by a gear-rack structure, an electric push rod structure, a hydraulic push rod structure, a belt drive structure, etc. At the same time, the cooperation between the slider 1205 and the slide rail can also be replaced by ways such as the cooperation between a linear bearing and a smooth shaft, and the cooperation between a roller 811 and a support surface.

[0068] A granular rubber hydraulic baler and a baling method. In order to realize the functions of automatic feeding, baling and discharging of rubber, the specific implementation steps are as follows:

[0069] At the beginning of S1, the system starts to work. The rubber scraps are conveyed by the conveyor belt from the previous process system, and the weighed rubber scraps are conveyed to the feed hopper of the hydraulic baler and fall into the packing box 801 with a packing push plate 1102 at the bottom to receive the materials;

[0070] After the rubber scraps are completely dropped, the hydraulic baler starts to run. That is, the cylinder 202 in the sealing plate mechanism 2 pushes the sealing plate 201 to seal the feed port and enclose the packing box 801 into a sealed cavity;

[0071] The first driving motor 805 in the packing box mechanism 8 runs to make the stroke cam 803 move. Driven by the stroke cam 803 and the scissor shaft 808, the packing box 801 moves upward to ensure that the packing box 801, the sealing plate 201 and the upper top plate 9 are in direct contact, so that the packing pressure during extrusion baling is borne by the upper top plate 9;

[0072] Subsequently, the hydraulic system 11 is started, and the packing push plate 1102 moves upward to extrude and bale the rubber scraps with the sealing plate 201 as the supporting bottom plate. The packing pressure is borne by the upper top plate 9 to complete the extrusion and baling work of the rubber;

[0073] When the hydraulic baling pressure reaches the extrusion rated pressure of the standard rubber bale, the packing push plate 1102 stays at this position for a certain time to keep the pressure on the standard rubber bale, and then the packing push plate 1102 moves downward to return to the initial zero position;

[0074] Immediately, the first driving motor 805 in the packing box mechanism 8 runs to make the stroke cam 803 move. Driven by the stroke cam 803 and the scissor shaft 808, the packing box 801 moves downward to return to the initial position, separating the packing box 801, the sealing plate 201 and the upper top plate 9 to make a clearance for the sealing plate 201 to return to zero;

[0075] The cylinder 202 in the sealing plate mechanism 2 runs to pull back the sealing plate 201 to make the sealing plate 201 return to the zero position, ensuring that the opening of the sealing plate 201 is aligned with the opening of the upper top plate 9 to make space for the standard rubber bale to leave the box;

[0076] The first driving motor 805 in the S8 packing box mechanism 8 operates to move the stroke cam 803. Driven by the stroke cam 803 and the scissors shaft 808, the packing box 801 moves upward to ensure direct contact among the packing box 801, the sealing plate 201, and the upper top plate 9. When the standard rubber package is discharged, the friction force between the rubber and the packing box 801 that needs to be overcome is borne by the upper top plate 9. When pushing the rubber out of the box, the stroke cam 803 is not stressed, ensuring the safety of the equipment.

[0077] The S9 hydraulic system 11 is started, and the packing push plate 1102 moves upward to the extreme position of the hydraulic system 11 to push out the finished standard rubber package in the packing box 801.

[0078] In S10, after the hydraulic press head pushes the finished rubber package to the extreme position, the second driving motor 1203 in the push plate 1202 mechanism is started. The push plate 1202 moves linearly on the second guide rail 1201 under the driving action of the traction chain 1208, and during the movement, the finished standard rubber package that has been packed is pushed out onto the discharge roller 4 to complete the discharge of the finished rubber package.

[0079] After the discharging is completed, the second driving motor 1203 of the push plate 1202 starts in the reverse direction to return the push plate 1202 to the initial zero position; at the same time, the hydraulic system 11 is started to return the hydraulic press head to the initial zero position; at the same time, the first driving motor 805 in the packing box mechanism 8 operates to move the stroke cam 803. Driven by the stroke cam 803 and the scissors shaft 808, the packing box 801 moves downward to return to the initial position, separating the packing box 801, the sealing plate 201, and the upper top plate 9 from each other, leaving a movement gap for the sealing of the sealing plate 201, and then starting the next packing work.

[0080] Through the above steps S1 to S11, the automatic feeding, extrusion packing, and discharging processes of the rubber are completed.
