Description

Technical Field

[0001] The invention relates to the technical field of foam scrap recycling, and in particular to a side scrap recycling device used in a foam processing production line. Background Art

[0002] Hard foam needs to be trimmed after molding to make its outer wall smooth and flat. In order to cut quickly, a thick hot knife is usually used for cutting. However, during cutting, the foam scraps will stick to the hot knife and cannot fall off on their own, which increases the difficulty of recycling.

[0003] In the prior art, tools are used to remove the scraps, but the scraps are always in contact with the hot knife after they are not cut, so that the temperature of the contact area between the scraps and the hot knife is relatively high, and a sticky substance is generated, resulting in excessive adhesion of the scraps. If a push plate is used at this time, the scraps may also break directly at the adhesion point, and if the cutting thickness is too large and the cutting time is too long, there may even be a fire hazard. Secondly, since the scraps and the foam body tightly wrap the hot knife, it is difficult for the heat near the hot knife to dissipate, the temperature rises, and the difficulty of temperature control is increased. Improper operation will cause the temperature of the hot knife close to the foam body to be slightly higher, resulting in arc burn marks and the cutting is not straight and smooth enough. Summary of the invention

[0004] The purpose of the present invention is to provide a side scrap material recovery device for a foam processing production line to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A side scrap recovery device for a foam processing production line comprises a machine tool, a conveying component is arranged on the machine tool, a cutting component is arranged on the side end of the machine tool, the cutting component comprises a hot knife and a hydraulic cylinder for driving the hot knife to move, and a supporting component is arranged on the top of the hot knife; the supporting component comprises a support plate, the bottom surface of the support plate is fixedly connected to the top surface of the hot knife, a plurality of movable grooves are arranged on the side end of the support plate, and a push-up component is arranged on the side end of the support plate, the push-up component comprises a push-up pipe, and the push-up pipe slides on the inner wall of the movable groove, and during the descending process of the hot knife, the push-up pipe slides outward and pushes the cut scraps, so that the scraps continue to tilt within a set angle range and do not fit the hot knife; an air blowing component is arranged on the push-up component, the interior of the push-up pipe is hollow, and an air blowing hole is arranged on the side end of the push-up pipe, and the air blowing component causes the air blowing holes of the plurality of push-up pipes to blow air at the same time, so that there is a gap between the foam scraps and the push-up pipe, so that the push-up pipe does not rub against the foam scraps during the downward movement.

[0007] Furthermore, a driving component is provided on the supporting component, and the driving component includes a movable shaft. Guide holes are opened on both sides of the support plate, and both ends of the movable shaft are respectively movable through the inside of a pair of guide holes and slide inside the support plate. Both ends of the movable shaft are fixedly connected with a stop block, and a limit box is provided on the outside of the machine tool. During the descending process of the movable shaft, the stop block touches the limit box, and a relative displacement occurs with the jacking pipe, thereby pushing each layer of the jacking pipe to move outward in turn.

[0008] Furthermore, there are multiple jacking pipes, and each of them is fixedly connected to the inner wall of the support plate with a reset member. During the descending process of the hot knife, the movable shaft moves upward relative to the support plate, so that the multiple jacking pipes move outward in sequence.

[0009] Furthermore, the guide hole includes a plurality of recessed portions and protruding portions, and the recessed portions and the protruding portions are both arc-shaped and distributed at intervals.

[0010] Furthermore, the blowing component includes a sealing plate, the interior of the limit box is hollow, the sealing plate slides inside the limit box, the top of the limit box is fixedly connected with a gas pipe, the gas pipe and a plurality of top pipes are interconnected, a connecting pipe is fixedly connected between an adjacent pair of top pipes, and the top gas can be transported to the inside of the top pipe through the gas pipe during the rising process of the sealing plate.

[0011] Furthermore, a transmission component is provided on the blowing component, and the transmission component includes a first fixed frame fixedly connected to the outer end of the limit box, a driving shaft is rotatably connected to the first fixed frame, a rope winding roller is fixedly sleeved on the driving shaft, a pulling member is fixedly wound around the rope winding roller, and one end of the pulling member is fixedly connected to the sealing plate.

[0012] Furthermore, a first pulley is fixedly sleeved on the driving shaft, a second fixing frame is fixedly connected to the outer end of the limit box near the bottom, a driven shaft is rotatably connected to the second fixing frame, a second pulley is fixedly sleeved on the driven shaft, a transmission belt is transmission-connected between the first pulley and the second pulley, a first pressure plate is fixedly connected to the transmission belt, a pressure rod is fixedly connected to the side end of the support plate, and one end of the pressure rod is fixedly connected to the second pressure plate.

[0013] Optionally, an intermittent connecting component is provided on the gas pipe, and the intermittent connecting component includes a first elastic sheet arranged on the inner wall of the gas pipe, a first magnetic sheet is fixedly connected to the first elastic sheet, a pair of fixed plates are fixedly connected to the inner wall of the support plate, and multiple top pipes close to the fixed plates are provided with air inlet holes, a second elastic sheet is provided on the inner wall of the air inlet holes, and a first magnetic sheet is fixedly connected to the second elastic sheet. When the first magnetic sheet and the second magnetic sheet are close to each other, they repel each other, so that the gas pipe and the corresponding top pipe can be connected to each other.

[0014] In the above technical solution, the side scrap material recovery device for the foam processing production line provided by the present invention has the following beneficial effects:

[0015] In this solution, during the descent of the hot knife, the movable shaft is moved upward relatively, so that the movable shaft swings along the guide hole. During the swinging process of the movable shaft, multiple jacking pipes are continuously pushed out, so that the multiple jacking pipes extend outward in sequence, and the cut scraps are stretched out, so that they no longer fit the hot knife, but are tilted within a set angle range, which not only reduces the heat transfer rate between the scraps and the hot knife, but also provides space for heat diffusion, so that the heat can be quickly dissipated at this location; by providing an air blowing component, not only is there a soft contact between the jacking pipe and the scraps, reducing the risk of premature rupture of the scraps, but also the jacking pipe will no longer rub against the scraps during the downward movement, thereby reducing the risk of generating more debris.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. Embodiment 1

[0030] See also Figure 1-4 , a side scrap material recovery device for a foam processing production line, comprising a machine tool 1, a conveying component 2 is arranged on the machine tool 1, a cutting component 4 is arranged at the side end of the machine tool 1, the cutting component 4 comprises a hot knife 41 and a hydraulic cylinder 42 for driving the hot knife 41 to move, and a supporting component 5 is arranged on the top of the hot knife 41;

[0031] The support component 5 includes a support plate 51, the bottom surface of the support plate 51 is fixedly connected to the top surface of the hot knife 41, a plurality of movable grooves are provided at the side end of the support plate 51, and a push-up component 6 is provided at the side end of the support plate 51, and the push-up component 6 includes a push-up pipe 61, and the push-up pipe 61 slides on the inner wall of the movable groove. During the descending process of the hot knife 41, the push-up pipe 61 slides outward and pushes the cut scraps, so that the scraps continue to tilt within the set angle range and do not fit the hot knife 41;

[0032] Specifically, the hot knife 41 designed in this case is a thick hot knife 41 with a thickness between 4-10 mm and good heat resistance, which makes its service life longer; the side end of the support plate 51 is fixedly connected with a lifting plate, and the top of the hydraulic cylinder 42 is fixedly connected to the lifting rod. The hydraulic cylinder 42 is arranged on the machine tool 1. When the hydraulic cylinder 42 is started, the support plate 51 and the hot knife 41 can be lowered. The support plate 51 is made of heat-resistant material, and the support plate 51 and the hot knife 41 are thermally isolated by heat insulation cotton.

[0033] The present invention also provides a conveying component 2 and a limiting component 3. The conveying component 2 is a reduction motor that rotates with multiple conveying rollers to transport the foam to the vicinity of the limiting component 3. The limiting component 3 is a pair of hydraulic cylinders that are controlled by a controller to control the foam. When cutting, the laser is used to align the position to be cut, and then the hot knife 41 is aligned with the laser line.

[0034] When it is necessary to cut the foam scraps, the hydraulic cylinder 42 can be driven to slowly lower the hot knife 41 to cut the scraps. During the cutting process, the top pipe 61 begins to extend to push the cut scraps away, making them tilted at 10-30 degrees so that they will not fit the hot knife 41.

[0035] A blowing component 7 is provided on the top opening component 6. The interior of the top pipe 61 is hollow. A blowing hole 62 is provided at the side end of the top pipe 61. The blowing component 7 allows the blowing holes 62 of multiple top pipes 61 to blow air at the same time, so that there is a gap between the foam scraps and the top pipe 61, so that the top pipe 61 does not rub against the foam scraps during the downward movement.

[0036] See also Figure 5 In an embodiment further provided by the present invention, a driving component 8 is provided on the supporting component 5, and the driving component 8 includes a movable shaft 81. Guide holes 52 are opened on both sides of the support plate 51. The two ends of the movable shaft 81 are respectively movable through the inside of a pair of guide holes 52 and slide inside the support plate 51. The two ends of the movable shaft 81 are fixedly connected with a stop block 82. A limit box 83 is provided on the outside of the machine tool 1. During the descending process of the movable shaft 81, the stop block 82 touches the limit box 83, and a relative displacement occurs with the jacking pipe 61, pushing each layer of the jacking pipe 61 to move outward in turn.

[0037] There are multiple jacking tubes 61, and each of them is fixedly connected to the inner wall of the support plate 51 with a reset member 63. When the hot knife 41 descends, the movable shaft 81 moves upward relative to the support plate 51, so that the multiple jacking tubes 61 move outward in sequence.

[0038] The guide hole 52 includes a plurality of recessed portions 521 and protruding portions 522 . Both the recessed portions 521 and the protruding portions 522 are arc-shaped and are spaced apart.

[0039] Specifically, when the movable shaft 81 moves to the protrusion 522, all the top pipes 61 squeezed here will slide outward (that is, the top pipes 61 of this layer will be pushed out each time), and when the movable shaft 81 moves to the intersection of the protrusion 522 and the recessed portion 521, the top pipes 61 below begin to retract and the top pipes 61 above begin to push outward until the movable shaft 81 reaches the position of the second protrusion 522 and pushes out the top pipes 61 of the second layer. One side of the top pipe 61 has a smooth curved surface structure, which is convenient for the movable shaft 81 to align and apply horizontal thrust, and is connected to the inner wall of the support plate 51 with a reset member 63, which is a reset spring and can automatically retract when the movable shaft 81 does not apply pressure to the top pipes 61 at this location.

[0040] The hydraulic cylinder 42 is turned on. The hydraulic cylinder 42 brings the support plate 51 and the hot knife 41 down, and the movable shaft 81 brings the stop block 82 down. After the stop block 82 touches the limit box 83, it stops descending, while the support plate 51 continues to descend. Therefore, the movable shaft 81 moves upward relative to the support plate 51 and moves along the guide hole 52. Since the guide hole 52 is divided into a recessed portion 521 and a protruding portion 522, the movable shaft 81 moves in a shaking upward state. During the shaking process of the movable shaft 81, multiple jacking pipes 61 are continuously pushed out, so that the multiple jacking pipes 61 extend outward in turn, and the cut scraps are stretched out, so that they are no longer in contact with the hot knife 41, but are tilted within a set angle range, which not only reduces the heat transfer rate between the scraps and the hot knife 41, but also provides space for heat diffusion, so that the heat at this location can be quickly dissipated.

[0041] See also Figure 6-7 In an embodiment further provided by the present invention, the blowing component 7 includes a sealing plate 71, the interior of the limit box 83 is hollow, the sealing plate 71 slides inside the limit box 83, and the top of the limit box 83 is fixedly connected with a gas pipe 72. The gas pipe 72 and the plurality of top pipes 61 are interconnected, and a connecting pipe 73 is fixedly connected between an adjacent pair of top pipes 61. During the rising process of the sealing plate 71, the top gas can be transported to the inside of the top pipe 61 through the gas pipe 72.

[0042] Specifically, the communication pipe 73 is a hose.

[0043] An air inlet hole is formed on the outer side of the limit box 83 , and the air inlet hole is located at the bottom and below the sealing plate 71 .

[0044] A transmission component 9 is arranged on the blowing component 7, and the transmission component 9 includes a first fixed frame 91 fixedly connected to the outer end of the limit box 83, and a driving shaft 92 is rotatably connected to the first fixed frame 91, a rope winding roller 93 is fixedly sleeved on the driving shaft 92, and a pulling member 94 is fixedly wound around the rope winding roller 93, and one end of the pulling member 94 is fixedly connected to the sealing plate 71.

[0045] A first pulley 95 is fixedly sleeved on the driving shaft 92, a second fixing frame 96 is fixedly connected to the outer end of the limit box 83 near the bottom, a driven shaft 97 is rotatably connected to the second fixing frame 96, a second pulley 98 is fixedly sleeved on the driven shaft 97, a transmission belt 99 is transmission-connected between the first pulley 95 and the second pulley 98, a first pressure plate 910 is fixedly connected to the transmission belt 99, a pressure rod 911 is fixedly connected to the side end of the support plate 51, and one end of the pressure rod 911 is fixedly connected to the second pressure plate 912.

[0046] Specifically, the pulling member 94 is a pulling rope, which is a thin rope with a thickness between 0.5-2 cm. As the number of winding turns increases, when the cutting is completed, the air pressure of the blown gas will increase to blow away the scraps, making the scraps easier to recycle.

[0047] When the support plate 51 descends, the pressure rod 911 and the second pressure plate 912 are also descended. When the second pressure plate 912 descends, the first pressure plate 910 is also descended, so that the first pressure plate 910 moves with the transmission belt 99. During the movement of the transmission belt 99, the first pulley 95 and the second pulley 98 are rotated, so that the driving shaft 92 rotates, and finally the purpose of rotating the rope roller 93 is achieved. The rotation of the rope roller 93 can lift the sealing plate 71 through the pulling member 94, so that the gas above the sealing plate 71 is transported to the multiple jacking pipes 61 through the gas pipe 72.

[0048] By providing the blowing component 7, not only can the top pipe 61 and the scraps be in soft contact, reducing the risk of premature rupture of the scraps, but the top pipe 61 will no longer be scratched against the scraps during the downward movement, thereby reducing the risk of generating more debris.

[0049] A collection box is also provided outside the machine tool, and the cut scraps fall into the collection box, thus completing the recycling of the foam scraps.

[0050] A control valve is also provided outside the limit box 83 , and an elastic member is fixedly connected between the sealing plate 71 and the inner bottom of the limit box 83 . The control valve is subsequently opened to return the sealing plate 71 to the initial position. Embodiment 2

[0051] See also Figure 8 The difference between the second embodiment and the first embodiment lies in the following technical features:

[0052] In an embodiment further provided by the present invention, an intermittent connecting component 10 is provided on the gas pipe 72, and the intermittent connecting component 10 includes a first elastic sheet 101 arranged on the inner wall of the gas pipe 72, and a first magnetic sheet 102 is fixedly connected to the first elastic sheet 101, and a pair of fixed plates 103 are fixedly connected to the inner wall of the support plate 51, and multiple top pipes 61 close to the fixed plate 103 are provided with air inlet holes, and a second elastic sheet 104 is provided on the inner wall of the air inlet hole, and the first magnetic sheet 102 is fixedly connected to the second elastic sheet 104. When the first magnetic sheet 102 and the second magnetic sheet 105 are close to each other, they repel each other, so that the gas pipe 72 and the corresponding top pipe 61 can be connected to each other.

[0053] Specifically, a pressure limiting valve is also provided on the gas pipe 72. When the gas pipe 72 is not aligned with the nearby top pipe 61, excess gas will be discharged through the pressure limiting valve. The gas pipe 72 extends to the interior of the fixed plate 103 and slides against the side wall of the fixed plate 103.

[0054] Specifically, in this solution, the top pipes 61 of each layer are connected by connecting pipes 73, but each layer is not connected to the top pipes 61 of the upper and lower layers by connecting pipes 73, that is, only one layer of connecting pipes 73 will blow air at a time, which greatly increases the air pressure of the blowing.

[0055] During the sliding process of the fixed plate 103, the pipe mouth of the air supply pipe 72 corresponds to the air inlet holes of multiple top pipes 61 in turn, and the first magnetic sheet 102 and the second magnetic sheet 105 are used in turn to connect the air supply pipe 72 with the corresponding top pipes 61, so that each layer of top pipes 61 can be supplied with air every time. The time period when each layer of top pipes 61 is ejected will also enter the blowing mode, which helps to tilt the cut scraps and separate them from the hot knife 41.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
