[0002] After waste cardboard is recycled, in order to be reused (common utilization methods include incineration or being used as bedding in livestock pens), the waste cardboard needs to be crushed. A common crushing device is a crusher, and a suction device is connected to the lower end of the crusher.

Detailed implementation manners

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0028] Example 1, refer toFigures 1 to 8 , which is the first embodiment of the present invention. This embodiment provides a crushing and screening device for waste cardboard recycling and processing, which can achieve the effect of screening out the plastic pull handle 104 on the cardboard body 103 from the cardboard body 103. It includes a screening component 100, which includes a crusher 101, a feed inlet 102 provided on the crusher 101, a cardboard body 103 provided in the feed inlet 102, a plastic pull handle 104 provided on the cardboard body 103, an inclined plate 105 provided on the upper side of the crusher 101, two positioning plates 106 provided on the inclined plate 105, hooks 107 provided on the two positioning plates 106, and an inclined surface 108 provided on the hook 107, an electric telescopic rod 109 provided on the upper side of the cardboard body 103, and the positioning plate 106 moves towards the cardboard body 103 to take out the plastic pull handle 104; a transmission component 200, which includes a sliding component 201 provided on the crusher 101, a receiving component 202 provided on the sliding component 201, and a guiding component 203 provided on the sliding component 201; a pressing component 300, which includes an elastic component 301 provided on the positioning plate 106, a guiding component 302 provided on the sliding component 201, and a one-way component 303 provided on the guiding component 302; a storage component 400, which includes an unfolding component 401 provided on the sliding component 201, and a recycling component 402 provided on the crusher 101

[0029] Specifically, the setting of the electric telescopic rod 109 can extrude the cardboard body 103 to avoid the phenomenon that the cardboard body 103 is pulled when the plastic pull handle 104 is taken out. Here, a conveying roller is provided on the inner wall of the feed inlet 102 of the crusher 101, which can convey the cardboard body 103. At the same time, a suction pipe is provided at the right end of the crusher 101, which can suck away the crushed cardboard body 103. Therefore, during the crushing process of the cardboard body 103, the phenomenon of blockage caused by the accumulation of shredded cardboard bodies 103 will not occur. This is the prior art and will not be elaborated here.

[0030] Furthermore, the sliding component 201 includes a protective cover 201a provided on the crusher 101. The electric telescopic rod 109 is fixedly connected to the protective cover 201a through a limit block. Electric sliding rails 201b are provided on the front and rear inner walls of the protective cover 201a. Sliding sleeves 201c are slidably connected to the two electric sliding rails 201b. A first L-shaped plate 201d is fixedly connected to the sliding sleeve 201c. A first cylinder 201e is fixedly connected to the first L-shaped plate 201d; the receiving component 202 includes a square block 202a that penetrates and is slidably connected to the first cylinder 201e. An installation sleeve 202b is fixedly connected to the square block 202a. Strip-shaped openings 202c are provided at the left end and the front and rear ends of the installation sleeve 202b. A screw 202d that abuts against the first cylinder 201e is threadedly connected to the square block 202a.

[0031] Among them, the protective cover 201a is composed of two baffle plates, an arc plate, and two side plates. The two baffle plates and an arc plate are combined into an arch-shaped structure. There is a gap between the bottoms of the two side plates and the feed inlet 102 of the crusher 101. At the same time, the right-end side plate can be disassembled to facilitate the maintenance of the electric telescopic rod 109 and the adjustment of the inclined plate 105. Here, the right-end side plate can be fixed to the arc plate and the baffle plate by bolts. The method is not unique as long as the side plate can be fixed and is convenient to disassemble.

[0032] Preferably, the guiding assembly 203 includes two telescopic sleeves 203a fixedly connected to the inclined plate 105. The diameter of the telescopic sleeve 203a is smaller than the diameter of the strip-shaped opening 202c. The front and rear ends of the protective cover 201a are respectively provided with a first guiding groove 203b, a second guiding groove 203c, a third guiding groove 203d, and a fourth guiding groove 203e that are connected end to end; the second guiding groove 203c is parallel to the fourth guiding groove 203e, and the slope of the first guiding groove 203b is smaller than the slope of the third guiding groove 203d.

[0033] It should be noted that the telescopic sleeve 203a is composed of two sleeves with different diameters and a telescopic spring. The setting of the telescopic sleeve 203a enables the position of the inclined plate 105 to be adjusted in the front and rear directions, suitable for taking out plastic pull handles 104 at different positions, and has a wider application. There is damping between the mounting sleeve 202b and the inclined plate 105, which can prevent the inclined plate 105 from automatically sliding down under the action of gravity.

[0034] During use, first turn the screw rod 202d to adjust the position of the square block 202a according to the position of the plastic pull handle 104 on the cardboard body 103, thereby adjusting the position of the mounting sleeve 202b and the position of the inclined plate 105, so that the position of the hook 107 changes, thus enabling the removal of the hook 107 at different positions. Then rotate the screw rod 202d to position the square block 202a. At this time, the telescopic sleeve 203a is at the connection of the first guide groove 203b and the second guide groove 203c. Then start the electric slide rail 201b to make the sliding sleeve 201c move to the left, so that the first L-shaped plate 201d moves to the left, driving the first cylinder 201e to move to the left, the square block 202a to move to the left, and the mounting sleeve 202b to move to the left, causing the inclined plate 105 to move to the left. When the inclined plate 105 moves to the left, the telescopic sleeve 203a slides in the first guide groove 203b, causing the inclined plate 105 to move towards the cardboard body 103. During this process, since the inclined plate 105 can slide in the mounting sleeve 202b, it will not be blocked. And because strip-shaped openings 202c are provided at the left end and the front and rear ends of the mounting sleeve 202b, the telescopic sleeve 203a will not be blocked when it moves. The movement of the inclined plate 105 towards the cardboard body 103 causes the hook 107 to move towards the cardboard body 103. When the telescopic sleeve 203a moves to the connection of the first guide groove 203b and the second guide groove 203c, the bottom of the hook 107 abuts against the upper surface of the cardboard body 103. As the electric slide rail 201b continues to move to the left, at this time the telescopic sleeve 203a slides in the second guide groove 203c. Here, the second guide groove 203c is parallel to the cardboard body 103. Thus, when the telescopic sleeve 203a moves in the second guide groove 203c, it will drive the inclined plate 105 to move upward along the cardboard body 103, so that the hook 107 slides along the side wall of the cardboard body 103 until the plastic pull handle 104 moves between the two hooks 107. Here, inclined surfaces 108 are provided on both of the two hooks 107. Thus, when the plastic pull handle 104 abuts against the hook 107, it is not easy for the two to get stuck. When the telescopic sleeve 203a is still at a certain distance from the connection of the second guide groove 203c and the third guide groove 203d, the plastic pull handle 104 completely enters between the two positioning plates 106. When the telescopic sleeve 203a moves to the connection of the second guide groove 203c and the third guide groove 203d, the plastic pull handle 104 abuts against the inclined plate 105. At this time, as the telescopic sleeve 203a continues to move to the left, the inclined plate 105 moves upward, and at this time the plastic pull handle 104 can be lifted to pull out the plastic pull handle 104. Then when the telescopic sleeve 203a moves to the connection of the third guide groove 203d and the fourth guide groove 203e, the plastic pull handle 104 is completely pulled out, and the lower end of the inclined plate 105 moves to the upper side of the feed port 102, so that the inclined plate 105 will not be blocked when it moves to the right. Then the electric telescopic rod 109 moves to the right, and through transmission, the telescopic sleeve 203a is reset along the fourth guide groove 203e.At this time, the inclined plate 105 moves to the right, driving the two positioning plates 106 to move to the right, causing the plastic handle 104 to move to the right until it reaches the right side of the feeding port 102, avoiding the situation where the plastic handle falls into the feeding port 102. It should be noted that arc edges are provided at the connection of the first guide groove 203b and the fourth guide groove 203e, and at the connection of the third guide groove 203d and the fourth guide groove 203e. When the telescopic sleeve 203a is at the connection of the third guide groove 203d and the fourth guide groove 203e, it can move to the right and enter the fourth guide groove 203e instead of the third guide groove 203d. The same is true for the connection of the first guide groove 203b and the fourth guide groove 203e, so as to move along the required trajectory.

[0035] In summary, by setting the transmission component 200, during the process of the electric slide rail 201b driving the sliding sleeve 201c to move to the left, the inclined plate 105 can be driven to move along a certain trajectory through transmission. Through the combination of the hook 107 on the inclined plate 105 and the positioning plate 106, when the inclined plate 105 moves, the positioning plate 106 and the hook 107 can extend to the lower side of the plastic handle 104 and lift the plastic handle 104 to separate the cardboard body 103 from the plastic handle 104, realizing the screening process.

[0036] Embodiment 2, referring to Figures 3 to 8 , is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a pressing component 300 for the waste cardboard recycling and processing crushing and screening equipment, which solves the problem of how to keep the plastic handle 104 from falling during the process of the inclined plate 105 moving to the right side of the feeding port 102. It includes an elastic component 301, which includes an opening 301a provided on the upper positioning plate 106. A second L-shaped plate 301b is slidably connected in the opening 301a. A pressing plate 301c is fixedly connected to the second L-shaped plate 301b. An elastic pad 301d is fixedly connected to the pressing plate 301c. The second L-shaped plate 301b is elastically connected to the upper positioning plate 106 through a first spring 301e; the guiding component 302 includes a guiding rod 302a fixedly connected to the L-shaped plate. A pair of extension blocks 302b are fixedly connected to the inner wall of the protective cover 201a. The extension blocks 302b are provided with a first arc-shaped opening 302c. The first arc-shaped opening 302c is communicated with a first horizontal opening 302d. A second arc-shaped opening 302e is provided on the first horizontal opening 302d. A third arc-shaped opening 302g connected to the left end of the first horizontal groove is communicated with the second arc-shaped opening 302e. The one-way component 303 includes an outward expansion groove 303a provided on the second arc-shaped opening 302e. A rotating shaft 303b is rotatably connected in the outward expansion groove 303a. A resisting block 303c is fixedly connected to the rotating shaft 303b. A torsion spring 303d is provided on the rotating shaft 303b. The left side wall of the resisting block 303c is close to the inner wall of the outward expansion groove 303a.

[0037] Specifically, the extension block 302b has a certain thickness, and the guide rod 302a is located in the middle of the extension block 302b, so that the guide rod 302a can be adjusted forward and backward for a certain distance. The adjustable distance is determined by the thickness of the extension block 302b. Therefore, when adjusting the position of the square block 202a, the phenomenon that the position of the square block 202a cannot be adjusted due to the guide rod 302a abutting against the extension block 302b will not occur. Here, the distance between the vertical sides of the L-shaped plate is greater than the distance between the two positioning plates 106. Thus, when the L-shaped plate moves downward, it can abut against the lower hook 107 to prevent the plastic handle 104 from slipping out between the two hooks 107. The left side wall of the abutting block 303c is close to the inner wall of the outward expansion groove 303a, so that the abutting block 303c can only rotate clockwise and cannot rotate counterclockwise. Therefore, the guide rod 302a can only move from the first horizontal opening 302d to the second arc-shaped opening 302e, rather than directly moving to the left end of the first horizontal opening 302d. A damper is provided on the second L-shaped plate 301b here to prevent the first spring 301e from contracting sharply.

[0038] During use, there is a gap between the guide rod 302a and the inner wall of the protective cover 201a here, so that it will not enter the first guide groove 203b. When the guide rod 302a moves to the connection between the first guide groove 203b and the second guide groove 203c, the guide rod 302a slides along the first arc-shaped opening 302c into the first horizontal opening 302d. Then, when there is still a certain distance between the telescopic sleeve 203a and the connection where the second guide groove 203c communicates with the third guide groove 203d, and the plastic pull handle 104 completely enters between the two positioning plates 106, the guide rod 302a moves to the connection between the first horizontal opening 302d and the second arc-shaped opening 302e. When the telescopic sleeve 203a moves to the connection where the second guide groove 203c communicates with the third guide groove 203d and the plastic pull handle 104 abuts against the inclined plate 105, the guide rod 302a moves to the connection between the second arc-shaped opening 302e and the second horizontal opening 302f, and then moves to the connection between the second horizontal opening 302f and the third arc-shaped opening 302g. During this process, when the guide rod 302a moves in the second arc-shaped opening 302e, it drives the second L-shaped plate 301b to move towards the hook 107 direction and drives the pressing plate 301c to move towards the plastic pull handle 104 direction. When the guide rod 302a moves to the connection between the second horizontal groove and the second arc-shaped opening 302e, the elastic pad 301d on the pressing plate 301c presses the plastic pull handle 104 tightly. The setting of the elastic pad 301d here can utilize the deformation of the elastic pad 301d to adapt to plastic pull handles 104 of different thicknesses. And at this time, the second L-shaped plate 301b abuts against the lower hook 107 to prevent the plastic pull handle 104 from slipping out between the two hooks 107. When the guide rod 302a slides in the second horizontal opening 302f, the position of the L-shaped plate remains unchanged. When the guide rod 302a moves into the third arc-shaped opening 302g, since the telescopic sleeve 203a also slides in the third guide groove 203d at this time, the two move synchronously. At the same time, there is a damping on the second L-shaped plate 301b here to prevent the first spring 301e from contracting sharply, causing the L-shaped plate to separate from the hook 107, and at the same time ensuring the stability of the pressing plate 301c. When the telescopic sleeve 203a moves into the fourth guide groove 203e, the guide rod 302a also moves into the first guide groove 203b. At this time, the pressing state of the pressing plate 301c is still maintained. Then, when the telescopic sleeve 203a moves in the fourth guide groove 203e, the guide rod 302a slides in the first horizontal opening 302d until the inclined rod moves to the right side of the feed port 102, and the guide rod 302a is aligned with the first arc-shaped opening 302c and slides out from the first arc-shaped opening 302c. At this time, under the action of the first spring 301e, the pressing plate 301c resets, making the extrusion contact. At this time, the plastic handle can be taken out. The slopes of the first guide groove 203b and the third guide groove 203d are set so that the time required for the inclined plate 105 to reset is different. When moving in the third guide groove 203d, the inclined plate 105 resets upward faster, thus preventing the reset of the first spring 301e from affecting the extrusion of the plastic pull handle 104.Meanwhile, when the inclined plate 105 moves to the left, the plastic handle 104 is always in contact with the side wall of the inclined plate 105, and it is not easy for the plastic handle 104 to fall off.

[0039] In summary, by setting the pressing component 300, while the inclined plate 105 is moving, the guide rod 302a can cooperate with the first arc-shaped opening 302c, the first horizontal opening 302d, the second arc-shaped opening 302e, the second horizontal opening 302f, and the third arc-shaped opening 302g to drive the pressing plate 301c to press the plastic handle 104, preventing the plastic handle 104 from falling into the feed port 102 during the movement.

[0040] Example 3, referring to Figures 3 to 8 , is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a storage component 400 for the waste cardboard recycling and processing crushing and screening equipment, which solves the problem of how to centrally recycle the plastic handle 104. It includes an unfolding component 401, which includes a fixed block 401a fixedly connected to the inner wall of the protective cover 201a. The fixed block 401a is fixedly connected with an arc-shaped elastic piece 401b. The inclined plate 105 is provided with an L-shaped groove 401c. An L-shaped rod 401d is slidably connected in the L-shaped groove 401c. A push block 401e cooperating with the positioning plate 106 is fixedly connected to the L-shaped rod 401d. An anti-disengagement opening 401f is provided on the side wall of the mounting sleeve 202b. A top rod 401g is slidably connected in the anti-disengagement opening 401f. The top rod 401g is fixedly connected with the L-shaped rod 401d. The recycling component 402 includes a bearing plate 402a fixedly connected to the crusher 101. A recycling box 402b is fixedly connected to the bearing plate 402a. A slideway 402c cooperating with the recycling box 402b is obliquely provided on the crusher 101.

[0041] Specifically, when the arc-shaped elastic piece 401b is squeezed and deformed, it can push the top rod 401g to move upward. Here, the slideway 402c is obliquely arranged. Thus, when the plastic handle 104 falls onto the slideway 402c, it can slide into the recycling box 402b for collection. When the recycling box 402b is full of plastic handles 104, the recycling box 402b can be directly replaced or emptied. Here, the push block 401e is relatively thick, and the upper end of the push block 401e is set to be arc-shaped to prevent the plastic handle 104 from resting on the push block 401e.

[0042] During use, when the telescopic sleeve 203a slides in the fourth guide groove 203e, the inclined plate 105 gradually approaches the arc-shaped elastic piece 401b, so that the mounting sleeve 202b gradually approaches the arc-shaped elastic piece 401b. When the inclined plate 105 moves to the right side of the feed port 102, the ejector rod 401g moves to the upper side of the arc-shaped elastic piece 401b, and the mounting sleeve 202b continues to move towards the arc-shaped elastic piece 401b. At this time, the arc-shaped elastic piece 401b can be squeezed, causing the arc-shaped elastic piece 401b to move towards the ejector rod 401g and push the ejector rod 401g upward, so that the L-shaped rod 401d moves obliquely upward. The anti-disengagement 401f is used for guiding. The width of the anti-disengagement 401f here is smaller than the width of the arc-shaped elastic piece 401b, so as to prevent the arc-shaped elastic piece 401b from getting stuck in the anti-disengagement 401f. The upward movement of the L-shaped rod 401d drives the push block 401e to move, thereby lifting the plastic pull handle 104 from the front end, causing the plastic pull handle 104 to fall from the positioning plate 106 onto the slideway 402c, and finally sliding into the recycling bin 402b for collection.

[0043] In summary, by setting the storage component 400, when the inclined plate 105 moves to the right side of the feed port 102, the ejector rod 401g can cooperate with the arc-shaped elastic piece 401b. Through extrusion, the arc-shaped elastic piece 401b deforms to push the ejector rod 401g, and through transmission, the push block 401e moves, lifting the plastic pull handle 104 at the front end, causing the plastic pull handle 104 to fall, and finally being guided into the recycling bin 402b through the slideway 402c to complete the collection.
