Description

Technical Field

[0001] The utility model belongs to the technical field of recycling and processing equipment, and relates to a briquetting machine, in particular to a spiral feeding briquetting machine. Background Art

[0002] In the field of mechanical processing, a large amount of chips are generated during machining. In the past, the method for dealing with iron chips after machining was to pile them up in a corner of the factory with a cart and then sell them directly to the scrap company. This treatment method not only has the disadvantages of occupying a large amount of limited space in the company, but also has the disadvantages of low profit for iron chip recycling, so someone proposed a briquetting machine.

[0003] There are various types of metal waste chip briquetting machines currently available on the market, such as the multi-screw feeding CNC automatic forming chip press with patent number 202321327031.9, which relates to the technical field of cutting material processing equipment, including a frame, a hopper, an upper feeding mechanism, a bottom feeding mechanism, an extrusion molding mechanism and an upper feeding inclination adjustment mechanism; a hopper is installed on the top of the frame, and the upper feeding mechanism is installed on the top of the hopper through the upper feeding inclination adjustment mechanism, and the bottom feeding mechanism is installed on the bottom of the hopper; the hopper is provided with a discharge slot at the end of the bottom feeding mechanism, and a molding cavity vertically connected to the discharge slot is provided on the base of the frame, an extrusion molding mechanism is installed on the rear side of the molding cavity, and a molding blocking mechanism is provided on the base of the frame.

[0004] The above-mentioned multi-screw feeding CNC automatic forming chip press can feed through the bottom feeding mechanism, namely the screw rod, but there are still the following defects: when the above-mentioned waste slag treatment machine is working, when encountering longer waste chips entering the waste chip bucket, the long waste chips are easy to be entangled on the screw rod. During operation, once the long waste chips are entangled on the screw rod, the waste chips will be stuck in the discharge channel, resulting in the inability to transport the waste chips into the forming mechanism. If necessary, the waste chips that are entangled on the screw rod and form a blockage can only be cleared manually, which greatly reduces the efficiency. The motor that drives the screw rod to rotate is connected to the end of the screw rod away from the forming mechanism. Therefore, when the waste chips are entangled and stuck on the end of the screw rod close to the forming mechanism, multiple torque will be applied to the screw rod, which will cause damage to the screw rod and the driving screw rod, greatly shortening the life of the equipment. Summary of the invention

[0005] The utility model aims to solve the above problems existing in the prior art and proposes a screw feeding briquetting machine, which solves the problems of easy blockage and low efficiency of the existing briquetting machines during operation.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A spiral feeding briquetting machine, comprising a main body, a feed hopper fixedly connected to the main body and provided with a feed opening, and a pressing mechanism fixedly connected to the main body and connected to the inner cavity of the feed hopper, the feed hopper also comprising a feeding part connected with the feed opening, a feeding screw rod which can rotate in a circumferential direction and pass through the feed hopper and has one end extending into the pressing mechanism is provided in the feeding part, a clearance opening only for the feeding screw rod to pass through is provided on a side wall of the feed hopper close to the pressing mechanism, and it is characterized in that the feed hopper is also provided with a feeding port connected with the clearance opening, a material blocking block fixedly connected to the feed hopper is provided in the feeding part, a side of the material blocking block close to the feeding screw rod has a material blocking wall flush with the edge of the clearance opening, and a side of the material blocking block close to the feeding port has an extrusion wall connected to the material blocking wall and flush with the edge of the feeding port, and the angle between the extrusion wall and the outer edge of the feeding screw rod decreases in the direction toward the material blocking wall.

[0008] During operation, the waste chips are poured into the feed port of the feed hopper, so that the waste chips fall into the feeding part. Since the feeding part is provided with a feeding screw rod which can rotate in the circumferential direction and penetrate the feed hopper and one end of which extends into the pressing mechanism, and the feed hopper is provided with a clearance port for only the feeding screw rod to pass through and an inlet connected to the clearance port, after the waste chips fall into the feeding part, the feeding screw rod rotates in the circumferential direction, so that the waste chips are pushed toward the inlet port along the axial direction of the feeding screw rod, so that the waste chips are gradually sent into the pressing mechanism through the inlet port, and then the pressing mechanism can make the waste chips entering the pressing mechanism be pressed into material blocks and sent out of the main body, thereby completing the recovery of the waste chips. By setting the feed port and the clearance port that only allows the feeding screw to pass through, and the blocking wall and extrusion wall on the blocking block, and because the blocking wall is flush with the edge of the clearance port, the extrusion wall is flush with the edge of the feed port, and the angle between the extrusion wall and the outer edge of the feeding screw gradually decreases in the direction toward the blocking wall, when the feeding screw rotates, the waste chips in the feed hopper will be gradually squeezed along the rotation direction of the feeding screw toward between the extrusion wall and the feeding screw, and when the waste chips are squeezed between the extrusion wall and the feeding screw, they will be blocked by the blocking wall. Therefore, after the feeding screw continues to rotate, the waste chips between the extrusion wall and the feeding screw will be gradually pushed axially. Specifically, the waste chips will be gradually pushed toward the feed port, so that the waste chips enter the pressing mechanism through the feed port.

[0009] Compared with the prior art, due to the extrusion wall and the material blocking wall as well as the setting of the give way and the feed inlet on the material blocking block, the gaps between long waste chips can be effectively eliminated when conveying waste chips, and the waste chips can be compressed into the space as much as possible before entering the inner cavity of the pressing mechanism through the feed inlet, thereby effectively preventing longer waste chips from being entangled on the feeding spiral rod, avoiding the situation where longer waste chips will be stuck due to entanglement, and no manual clearing is required, thereby greatly improving work efficiency.

[0010] In the above-mentioned spiral feeding briquetting machine, the feeding screw rod is a right-handed threaded rod, and the screwing direction is towards the clearance opening.

[0011] Specifically, the feeding screw is a right-handed thread, and when the feeding screw is viewed from the direction away from the pressing mechanism from the clearance port, the feeding screw rotates counterclockwise. Therefore, when the feeding screw rotates counterclockwise, the waste chips on the feeding screw can be pushed, so that the waste chips are squeezed toward the extrusion wall and the feeding screw. Since the feeding screw is screwed in toward the clearance port, when the waste chips are squeezed between the extrusion wall and the feeding screw, they can be pushed axially toward the feed port by the feeding screw, so that the waste chips enter the pressing structure through the feed port.

[0012] In the above-mentioned spiral feeding briquetting machine, the feeding screw rod includes an extrusion screw rod with one end extending into the inner cavity of the pressing mechanism and an auxiliary pushing screw rod connected to the extrusion screw rod and coaxially arranged, the blocking block is located on one side of the extrusion screw rod, and extrusion sheets are evenly distributed on the edge of the extrusion screw rod along the rotation direction.

[0013] Since the material blocking block is specifically fixed to the inner wall of the feed hopper on one side of the extrusion screw rod, the waste chips will be rolled into the space between the extrusion wall and the extrusion screw rod only when they are on the extrusion screw rod, so that the long waste chips are compressed and then sent into the inner cavity of the pressing mechanism; through the setting of the auxiliary pushing screw rod, the waste chips on the auxiliary pushing screw rod will only be pushed in the direction of the extrusion screw rod instead of being squeezed, thereby preventing the extrusion stroke of the extrusion screw rod from being too long, which would cause excessive torque and damage the feeding screw rod; and through the setting of the extrusion sheet, the contact area between the extrusion screw rod and the waste chips can be increased, so that the waste chips can be squeezed into the space between the extrusion wall and the extrusion screw rod more efficiently and easily, and can further prevent the long waste chips from being entangled on the extrusion screw rod.

[0014] In the above-mentioned spiral feeding briquetting machine, the end of the extruding sheet facing the rotation direction of the extruding screw rod is at an acute angle.

[0015] The end of the extrusion piece facing the rotation direction of the extrusion screw rod is at an acute angle, specifically a triangular shape, so that during the rotation of the extrusion screw rod, the extrusion piece can more easily hook the long waste chips and squeeze them into between the extrusion screw rod and the extrusion wall, and through the extrusion piece, the long waste chips will be extremely shortened during the extrusion process, thereby further reducing the gap between the waste chips, avoiding the waste chips from being stuck during the feeding process, and further improving the feeding efficiency of this spiral feeding briquetting machine.

[0016] In the above-mentioned spiral feeding briquetting machine, the diameter of the auxiliary pushing screw is larger than the diameter of the extrusion screw, and a bearing ring seat that penetrates the feed hopper and extends into the feeding part is fixed on the side wall of the feed hopper away from the pressing mechanism. The auxiliary pushing screw is sleeved outside the bearing ring seat, and the feeding screw also includes a connecting rod that is arranged in the auxiliary pushing screw and is connected to the extrusion screw and passes through the bearing ring seat. A driving mechanism connected to the connecting rod is also fixed in the main body.

[0017] Specifically, since the driving mechanism is connected to the connecting rod, and the connecting rod is connected to the extrusion screw rod, after the connecting rod is driven to rotate by the driving mechanism, the connecting rod drives the extrusion screw rod to rotate to extrude the waste chips, and is fixed to the inner wall of the feed hopper through a bearing seat, and at the same time, the auxiliary pushing screw rod is sleeved outside the bearing seat. By making the diameter of the auxiliary pushing screw rod larger than the diameter of the extrusion screw rod, the strength and rigidity of the overall structure of the feeding screw rod can be enhanced, and part of the feeding screw rod can be used for extrusion, while the other part only assists in pushing the material without extruding the material, so that the feeding screw rod will not generate excessive torque when extruding the waste chips, thereby improving the service life of the spiral feeding briquetting machine.

[0018] In the above-mentioned spiral feeding briquetting machine, the driving mechanism includes a driving motor fixed in the main body, and the output end of the driving motor is fixedly connected to a driving wheel, and the end of the connecting rod away from the extrusion screw rod is connected to a driven wheel meshing with the driving wheel.

[0019] Since the driving wheel is fixedly connected to the output end of the driving motor, the driving wheel can be driven to rotate after the driving motor is started. Since the driving wheel is meshed with the driven wheel, and the driven wheel is fixedly connected to the end of the connecting rod away from the extrusion screw rod, the driving wheel can drive the driven wheel to rotate after it rotates, thereby driving the feeding screw rod to rotate counterclockwise, so that the waste chips are gradually squeezed toward the space between the extrusion wall and the feeding screw rod, and pushed into the pressing mechanism along the axial direction.

[0020] In the above-mentioned spiral feeding briquetting machine, one end of the connecting rod away from the extrusion screw rod is fixedly connected to a fixing seat, and the driven wheel is fixedly connected to the fixing seat via a fastener.

[0021] Specifically, the fixing seat is connected to the connecting rod through a key connection, and the driven wheel is fixedly connected to the fixing seat through a fastener, so that the driven wheel can be detachably connected, so that a new driven wheel can be quickly and conveniently replaced after the driven wheel is worn or damaged.

[0022] In the above-mentioned spiral feeding briquetting machine, a clearance groove is provided on the inner wall of the feed hopper, and the clearance groove is located in the feeding part, and the clearance groove is located on the side of the extrusion wall away from the blocking wall.

[0023] Since the waste chips are retained for a certain period of time during the extrusion process when the extrusion screw is extruding, the arrangement of the give-way groove on the inner wall of the feed hopper on the side of the extrusion wall away from the baffle wall allows more un-extruded waste chips to be stored in the give-way groove first, thereby reducing the pressure on the extrusion screw, so that too much waste chips will not instantly enter between the extrusion screw and the extrusion wall and be squeezed, thereby further improving the service life of the spiral feeding briquetting machine.

[0024] In the above-mentioned spiral feeding briquetting machine, a pushing mechanism is also fixedly connected in the main body, and the pressing mechanism includes a pressing barrel fixedly connected in the main body and connected with the make way port and the feed port, and a pressing rod arranged in the pressing barrel and capable of sliding toward the pushing mechanism. The pushing mechanism passes through one end of the pressing barrel away from the pressing rod, and the inner cavity of the pushing mechanism is connected with the inner cavity of the pressing barrel. A discharge port is opened on the main body, and a pushing rod capable of sliding toward the discharge port is slidably arranged in the pushing mechanism.

[0025] Specifically, the pressing cylinder is fixedly connected to the main body, and a pressing rod that can slide axially is slidably arranged in the pressing cylinder. When the waste chips are initially squeezed by the feeding spiral rod and pushed into the inlet and enter the pressing cylinder, the pressing rod slides toward the pushing mechanism, fully squeezing the waste chips and pushing them into the inner cavity of the pushing structure. Since the main body is provided with a discharge port and the pushing mechanism is slidably arranged with a pushing rod that can slide toward the discharge port, when the waste chips are fully squeezed by the pressing rod into waste blocks and pushed into the inner cavity of the pushing mechanism, the pushing rod is driven to slide toward the discharge port to push the compressed waste blocks out of the discharge port.

[0026] Compared with the prior art, this briquetting machine has the following advantages:

[0027] 1. This spiral feeding briquetting machine can effectively eliminate the gaps between long waste chips when conveying waste chips through the arrangement of the extrusion wall and the blocking wall as well as the give way and the feed port, and compress the waste chips into space as much as possible before entering the inner cavity of the pressing mechanism through the feed port, thereby effectively preventing longer waste chips from winding around the feeding spiral rod, avoiding the situation where longer waste chips are stuck and blocked due to winding, and no manual unblocking is required, thereby greatly improving work efficiency.

[0028] 2. The arrangement of the extrusion sheet can increase the contact area between the extrusion screw and the waste chips, so that the waste chips can be squeezed between the extrusion wall and the extrusion screw rod more efficiently and easily, and can further prevent long waste chips from being entangled on the extrusion screw rod.

DETAILED DESCRIPTION

[0042] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0043] like Figures 1 to 12 As shown, a spiral feeding briquetting machine comprises a main body 1, a feeding hopper 2 fixedly connected to the main body 1 and provided with a feeding port 2a, and a pressing mechanism 7 fixedly connected to the main body 1 and connected to the inner cavity of the feeding hopper 2. The feeding hopper 2 also comprises a feeding portion 2b connected to the feeding port 2a, and a feeding screw rod 4 which can rotate in the circumferential direction and penetrate the feeding hopper 2 and one end of which extends into the pressing mechanism 7 is provided in the feeding portion 2b. A clearance port 2d for only the feeding screw rod 4 to pass through is provided on a side wall of the feeding hopper 2 close to the pressing mechanism 7. It is characterized in that the feed hopper 2 is also provided with a feeding port 2e connected to the clearance port 2d, and the feeding part 2b is provided with a material blocking block 5 fixedly connected to the feed hopper 2, and the side of the material blocking block 5 close to the feeding screw rod 4 has a material blocking wall 5a flush with the edge of the clearance port 2d, and the side of the material blocking block 5 close to the feeding port 2e has an extrusion wall 5b connected to the material blocking wall 5a and flush with the edge of the feeding port 2e, and the angle between the extrusion wall 5b and the outer edge of the feeding screw rod 4 decreases in the direction toward the material blocking wall 5a. During operation, the waste chips are poured into the feed port 2a of the feed hopper 2, so that the waste chips fall into the feed part 2b. Since the feed part 2b is provided with a feed screw rod 4 which can rotate in the circumferential direction and penetrate the feed hopper 2 and one end of which extends into the pressing mechanism 7, and the feed hopper 2 is provided with a clearance port 2d for only the feed screw rod 4 to pass through and an inlet 2e connected to the clearance port 2d, after the waste chips fall into the feed part 2b, the feed screw rod 4 rotates in the circumferential direction, so that the waste chips are pushed toward the inlet 2e along the axial direction of the feed screw rod 4, so that the waste chips are gradually sent into the pressing mechanism 7 through the inlet port 2e, and then the pressing mechanism 7 can make the waste chips entering the pressing mechanism 7 be pressed into material blocks and sent out of the main body 1, thereby completing the recovery of the waste chips. By setting the feed port 2e and the clearance port 2d that only allows the feeding screw 4 to pass through, and the blocking wall 5a and extrusion wall 5b on the blocking block 5, and because the blocking wall 5a is flush with the edge of the clearance port 2d, and the extrusion wall 5b is flush with the edge of the feed port 2e, and the angle between the extrusion wall 5b and the outer edge of the feeding screw 4 gradually decreases in the direction toward the blocking wall 5a, when the feeding screw 4 rotates, the waste chips in the feed hopper 2 will be gradually squeezed along the rotation direction of the feeding screw 4 toward the extrusion wall 5b and the feeding screw 4, and when the waste chips are squeezed to between the extrusion wall 5b and the feeding screw 4, they will be blocked by the blocking wall 5a. Therefore, after the feeding screw 4 continues to rotate, the waste chips located between the extrusion wall 5b and the feeding screw 4 will be gradually pushed along the axial direction. Specifically, the waste chips will be gradually pushed toward the feed port 2e, so that the waste chips enter the pressing mechanism 7 through the feed port 2e.

[0044] like Figures 1 to 12 As shown, further, the feeding screw rod 4 is a right-handed threaded rod, and the screwing direction is screwing in toward the clearance port 2d. Specifically, the feeding screw rod 4 is a right-handed thread, and when the feeding screw rod 4 is viewed from the direction away from the clearance port 2d from the pressing mechanism 7, the feeding screw rod 4 rotates counterclockwise, so that when the feeding screw rod 4 rotates counterclockwise, the waste chips on the feeding screw rod 4 can be pushed, so that the waste chips are squeezed toward the extrusion wall 5b and the feeding screw rod 4. Since the screwing direction of the feeding screw rod 4 is screwing in toward the clearance port 2d, when the waste chips are squeezed between the extrusion wall 5b and the feeding screw rod 4, they can be pushed axially by the feeding screw rod 4 toward the direction of the feed port 2e, so that the waste chips enter the pressing structure through the feed port 2e.

[0045] like Figures 1 to 12 As shown, further, the feeding screw 4 includes an extrusion screw 4a with one end extending into the inner cavity of the pressing mechanism 7 and an auxiliary pushing screw 4b connected to the extrusion screw 4a and coaxially arranged, the blocking block 5 is located on one side of the extrusion screw 4a, and the extrusion sheets 3 are evenly distributed on the edge of the extrusion screw 4a along the rotation direction. Since the material blocking block 5 is specifically fixed to the inner wall of the feed hopper 2 on one side of the extrusion screw rod 4a, the waste chips will be rolled into the space between the extrusion wall 5b and the extrusion screw rod 4a only when they are on the extrusion screw rod 4a, so that the long waste chips are compressed and then sent into the inner cavity of the pressing mechanism 7. Through the setting of the auxiliary pushing screw rod 4b, the waste chips on the auxiliary pushing screw rod 4b will only be pushed in the direction of the extrusion screw rod 4a instead of being squeezed, thereby preventing the extrusion stroke of the extrusion screw rod 4a from being too long, resulting in excessive torque and thus damaging the feeding screw rod 4, and through the setting of the extrusion sheet 3, the contact area between the extrusion screw rod 4a and the waste chips can be increased, so that the waste chips can be squeezed into the space between the extrusion wall 5b and the extrusion screw rod 4a more efficiently and easily, and can further prevent the long waste chips from being entangled on the extrusion screw rod 4a.

[0046] like Figures 1 to 12 As shown, further, the end of the extrusion sheet 3 facing the rotation direction of the extrusion screw rod 4a is at an acute angle. The end of the extrusion sheet 3 facing the rotation direction of the extrusion screw rod 4a is at an acute angle, specifically a triangular shape, so that during the rotation of the extrusion screw rod 4a, the extrusion sheet 3 can more easily hook the long waste chips and squeeze them between the extrusion screw rod 4a and the extrusion wall 5b, and through the extrusion sheet 3, the long waste chips will be extremely shortened during the extrusion process, thereby further reducing the gap between the waste chips and preventing the waste chips from being stuck during the feeding process, further improving the feeding efficiency of this spiral feeding briquetting machine.

[0047] like Figures 1 to 12As shown, further, the diameter of the auxiliary push screw 4b is greater than the diameter of the extrusion screw 4a, and a bearing ring seat 10 that penetrates the feed hopper 2 and extends into the feeding portion 2b is fixed on a side wall of the feed hopper 2 away from the pressing mechanism 7. The auxiliary push screw 4b is sleeved outside the bearing ring seat 10. The feeding screw 4 also includes a connecting rod 4c that is arranged in the auxiliary push screw 4b and is connected to the extrusion screw 4a and passes through the bearing ring seat 10. A driving mechanism 6 connected to the connecting rod 4c is also fixed in the main body 1. The driving mechanism 6 includes a driving motor 6a fixed in the main body 1, and the output end of the driving motor 6a is fixedly connected to the driving wheel 6b, and the end of the connecting rod 4c away from the extrusion screw rod 4a is connected to the driven wheel 6c meshing with the driving wheel 6b. Specifically, the driven wheel 6c is sleeved on the connecting rod 4c and is circumferentially fixed to the connecting rod 4c through a key connection, and then an expansion sleeve is installed on the connecting rod 4c, and the expansion sleeve abuts against the side of the driven wheel 6c away from the pressing mechanism 7 to achieve axial positioning of the driven wheel 6c. Specifically, rolling bearings 12 are installed at both ends of the bearing ring seat 10. The connecting rod 4c passes through the bearing ring seat 10 and cooperates with the rolling bearing 12 to realize the positioning of the feeding connecting rod 4c. Therefore, after the connecting rod 4c is driven to rotate by the driving mechanism 6, the connecting rod 4c drives the extrusion screw rod 4a to rotate to extrude the waste chips, and is fixed to the inner wall of the feed hopper 2 through the bearing seat. At the same time, the auxiliary pushing screw rod 4b is sleeved on the outside of the bearing seat. By making the diameter of the auxiliary pushing screw rod 4b larger than the diameter of the extrusion screw rod 4a, the strength and rigidity of the overall structure of the feeding screw rod 4 can be enhanced, and part of the feeding screw rod 4 is used for extrusion, while the other part only assists in pushing but does not extrude, so that the feeding screw rod 4 will not generate excessive torque when extruding the waste chips, thereby improving the service life of the spiral feeding briquetting machine.

[0048] More specifically, since the driving wheel 6b is fixedly connected to the output end of the driving motor 6a, the driving wheel 6b can be driven to rotate after the driving motor 6a is started. Since the driving wheel 6b is meshed with the driven wheel 6c, and the driven wheel 6c is fixedly connected to the end of the connecting rod 4c away from the extrusion screw rod 4a, the driving wheel 6b can drive the driven wheel 6c to rotate after it rotates, thereby driving the feeding screw rod 4 to rotate counterclockwise, so that the waste chips are gradually squeezed toward the space between the extrusion wall 5b and the feeding screw rod 4, and pushed into the pressing mechanism 7 along the axial direction.

[0049] like Figures 1 to 12As shown, further, one end of the connecting rod 4c away from the extrusion screw rod 4a is fixedly connected to a fixing seat 11, and the driven wheel 6c is fixedly connected to the fixing seat 11 through a fastener. Specifically, the driven wheel 6c abuts between the fixing seat 11 and the expansion sleeve. Since the fixing seat 11 is connected to the connecting rod 4c through a key connection, the driven wheel 6c is fixedly connected to the fixing seat 11 through the fastener, and the end of the driven wheel 6c away from the fixing seat 11 abuts against the expansion sleeve, thereby realizing the detachable connection between the axial positioning of the driven wheel 6c and the fixing seat 11, so that the new driven wheel 6c can be quickly and conveniently replaced after the driven wheel 6c is worn or damaged.

[0050] like Figures 1 to 12 As shown, further, a clearance groove 2c is provided on the inner wall of the feed hopper 2, and the clearance groove 2c is located in the feeding part 2b, and the clearance groove 2c is located on the side of the extrusion wall 5b away from the blocking wall 5a. Since the waste chips are retained for a certain period of time during the extrusion process when the extrusion screw rod 4a is extruding the waste chips, more waste chips that are not squeezed can be stored in the clearance groove 2c first by setting the clearance groove 2c on the inner wall of the feed hopper 2 on the side of the extrusion wall 5b away from the blocking wall 5a, thereby reducing the pressure of the extrusion screw rod 4a, so that too much waste chips will not enter between the extrusion screw rod 4a and the extrusion wall 5b and be squeezed, thereby further improving the service life of the spiral feeding briquetting machine.

[0051] like Figures 1 to 12 As shown, further, a pushing mechanism 8 is fixedly connected in the main body 1, and the pressing mechanism 7 includes a pressing barrel 7a fixedly connected in the main body 1 and connected with the make way port 2d and the feed port 2e, and a pressing rod 7b arranged in the pressing barrel 7a and capable of sliding toward the pushing mechanism 8. The pushing mechanism 8 passes through one end of the pressing barrel 7a away from the pressing rod 7b, and the inner cavity of the pushing mechanism 8 is connected with the inner cavity of the pressing barrel 7a. A discharge port 1a is opened on the main body 1, and a pushing rod 9 capable of sliding toward the discharge port 1a is slidably arranged in the pushing mechanism 8. Specifically, the pressing barrel 7a is fixedly connected to the main body 1, and a pressing rod 7b that can slide axially is slidably provided in the pressing barrel 7a. When the waste chips are initially squeezed by the feeding screw rod 4 and pushed into the inlet 2e and enter the pressing barrel 7a, the pressing rod 7b slides toward the pushing mechanism 8, fully squeezing the waste chips and pushing the waste chips into the inner cavity of the pushing structure. Since the main body 1 is provided with a discharge port 1a, and since a pushing rod 9 that can slide toward the discharge port 1a is slidably provided in the pushing mechanism 8, when the waste chips are fully squeezed by the pressing rod 7b into waste blocks and pushed into the inner cavity of the pushing mechanism 8, the pushing rod 9 is driven to slide toward the discharge port 1a to push the compressed waste blocks out of the discharge port 1a.

[0052] More specifically, the pressing rod 7b and the pushing rod 9 achieve axial sliding via a pneumatic cylinder or a hydraulic cylinder.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
