Description

Technical Field

[0001] This invention belongs to the technical field of plastic processing equipment, specifically a pressure cutting processing equipment for processing plastic products. Background Technology

[0002] Plastic products are various items made from plastics and can be widely used in different fields, such as home furnishings, electronics, medical, automotive, and construction industries. Plastic materials have many advantages, such as being lightweight, corrosion-resistant, having good insulation properties, and being low-cost, thus they are widely used in modern industrial production. There are usually several processing methods for plastic products; for elastic plastic products, compression cutting is a common method.

[0003] Existing die-cutting equipment for plastic product processing typically uses a press to drive a die frame downwards to cut the plastic product. After cutting, a spring-connected push plate, pre-installed in the die frame, automatically ejects the cut plastic product downwards, achieving automatic discharge. However, because the bottom discharge port remains open throughout the cutting and automatic ejection process, while it can be used for rigid plastic products (which can be supported above the discharge port without sufficient bottom support), it becomes ineffective when die-cutting more elastic plastic products. Due to the elasticity of these products, the existing die-cutting frame struggles to effectively cut them without sufficient bottom support. Without upward support at the bottom discharge port, the elastic plastic product at the cut point deforms and stretches downwards through the fixed discharge port during die-cutting, preventing proper die-cutting. Therefore, current die-cutting equipment has a limited range of applications and cannot quickly and effectively automatically cut and discharge a wider range of elastic plastic products, resulting in poor performance.

[0004] Furthermore, existing plastic product processing cutting equipment often requires power equipment for feeding, cutting, and automatic feeding during operation. Feeding and cutting are intermittent; that is, cutting can only occur after feeding is complete, and the next feeding can only begin after cutting is complete. This necessitates frequent start-stop cycles for the feeding power equipment. When the feeding pushes the plastic product to the cutting position, the machine must stop to wait for cutting. However, in continuous large-volume cutting, frequent start-up and control of the feeding power equipment significantly impacts its stability and lifespan. Moreover, starting and control require the addition of electrical control equipment, resulting in a large investment and poor performance. Summary of the Invention

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention, by installing a rotatable switching component on the top of the workbench, works in conjunction with the downward cutting of the cutting unit. During cutting, the rotating disk provides support, supporting the bottom of the elastic plastic and completing the cutting. During the cutting process, the cutting unit automatically pushes the control unit to change the ventilation direction of the distribution component. After cutting, an air pump guides the supplied gas into the pushing component, causing the pushing component to rotate the switching component. The rotating disk rotates and switches the adapter port to the bottom of the cut elastic plastic product. Combined with the elastic force of the first spring, the cut plastic product is automatically ejected along the adapter port and the bottom of the discharge port, completing automatic discharge. Thus, when dealing with elastic plastic products, by rotating the intermittently supporting and opening rotating disk, coordination between support and rapid discharge is achieved. This provides stable support for elastic plastic products while achieving rapid automatic discharge, greatly expanding the application range of cutting plastic products with different properties.

[0022] 2. This invention utilizes the ventilation of the distribution component, along with the arrangement and connection of the turbine mechanism and the pushing component, to start the air pump in the distribution component before the pressing and cutting begins. This drives the turbine mechanism and enables the pushing component to automatically feed the plastic product. When the pressing and cutting action occurs, the pressing and cutting part drives the control part to move downward, changing the air supply direction of the air pump. Without stopping the air pump, the gas is directly guided to the pushing component through the control part, completing the rotation of the switching component. Thus, throughout the continuous process of feeding and pressing, the invention provides feeding. The power source air pump never needs to be stopped, and there is no need to add electrical equipment to control the start. After the pressing and cutting is completed, the air pump changes the airflow direction again to start the next round of automatic feeding. This avoids the frequent start and stop of the existing feeding power source, reduces the risk of power source failure, and the pressing and cutting process is simple and automatic to control. The power source runs stably. In addition to serving as the feeding power source, the air pump also provides power for the rotation of the switching components through the reversing airflow effect, realizing the pressing and cutting of elastic plastic products and automatic discharge. There is no need to add an additional power source, and continuous pressing and cutting does not require frequent start and stop.

[0023] 3. This invention utilizes the air pump's air supply again, combined with the manual up-and-down movement of the control unit, to intermittently introduce gas into the pushing component. This allows for intermittent rotation of the switching component in the early stages of pressing and cutting, in conjunction with the reciprocating rotation of the rotating plate. The frosted surface on the top of the rotating plate is used to polish the rigid plastic product before pressing and cutting, meeting the processing needs of more comprehensive plastic products. This invention offers more comprehensive functions, further reduces subsequent processing steps for rigid plastic products, and results in better processing effects. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 13 As shown, this embodiment of the invention provides a pressure cutting processing device for plastic products, including a worktable 1 and a power arm 2. The power arm 2 is fixedly installed on the worktable 1. The bottom surface of the worktable 1 is provided with a discharge hole 4. The movable end of the power arm 2 is fixedly installed with a pressure cutting part 5. The top surface of the worktable 1 is rotatably installed with a switching assembly 13. The pressure cutting part 5 is located on one side above the switching assembly 13. The bottom surface of the worktable 1 is provided with a pushing assembly 6. The pushing assembly 6 is meshed with the switching assembly 13. The front and top of the worktable 1 are respectively provided with a distribution assembly 8 and a pushing assembly 10. The front end of the pushing assembly 10 is provided with a turbine mechanism 11. The turbine mechanism 11 and the distribution assembly 8 are fixedly connected by a connecting pipe 12. The distribution assembly 8 is fixedly connected to the pushing assembly 6. The top of the distribution assembly 8 is movably installed with a control part 9.

[0040] The switching component 13 includes a rotating disk 131, a rotating shaft 132, a first gear 133, and an adapter port 134. The rotating disk 131 is rotatably sleeved on the top of the worktable 1, the rotating shaft 132 is fixedly connected to the bottom of the rotating disk 131, the first gear 133 is fixedly sleeved on the rotating shaft 132, and the top of the rotating disk 131 is provided with a frosted surface.

[0041] The push assembly 6 includes a toothed plate 61, a fixed frame 62, a movable rod 63, a second spring 64, and a slide rod 65;

[0042] The pressure cutting part 5 includes a top plate 51, a mold frame 52, a reserved plate 53, a first spring 54, a horizontal plate 55, and a push rod 56;

[0043] The control unit 9 includes a movable column 91, a vent 92, a first blind hole 93, a second blind hole 94, and a bypass pipe 95;

[0044] The dispensing assembly 8 includes an air pump 81, a dispensing frame 82, a first sleeve 83, a second sleeve 84, an intermediate tube 85, and a third spring 86.

[0045] First embodiment: Before the pressure cutting process, the elastic plastic is passed through the guide port 102 of the pusher assembly 10. Before the pressure cutting action, the distribution assembly 8 is started, and the air pump 81 guides the initially blown gas through the air outlet 88 and the connecting pipe 12 to the turbine mechanism 11. Under the blowing of the high-speed airflow, the turbine mechanism 11 drives the single pusher roller 103 to rotate. With the meshing and rotation of the two No. 2 gears 104, the upper and lower distributed pusher rollers 103 rotate simultaneously and push the plastic forward along the upper and lower surfaces. When the elastic plastic product moves to the position to be pressure cut, the power arm 2 is started, so that the pressure cutting part 5 moves downward and the mold frame 52 first connects. The plastic part touches the top surface and performs an initial cut. As the mold frame 52 continues to descend and cut, the cut plastic product gradually fills the interior of the mold frame 52, pushing the reserved plate 53 upward and compressing the first spring 54. The cut plastic product is completely cut off. As the cutting part 5 descends and cuts, the push rod 56 contacts the control part 9 before the cutting begins, and further pushes the control part 9 downward along the interior of the first sleeve 83 and the second sleeve 84 during the cutting process. As the movable column 91 is pushed downward during the cutting process, the vent 92 gradually descends and is offset from the air outlet 88. At the same time, the first blind hole 93 is connected to the air outlet 88, and the air pump 81 directly outputs air. The gas is guided through blind holes 93 and 94 into the internal cavity 87 of the distribution frame 82, and continuously fills the fixed frame 62 of the pushing assembly 6. The pressurized gas pushes the movable rod 63 laterally within the fixed frame 62. As the second spring 64 stretches, the toothed plate 61 gradually moves laterally, driving the meshing first gear 133 to rotate. This causes the rotating shaft 132 to drive the rotating disk 131 to rotate. As the rotating disk 131 rotates at the bottom of the mold frame 52, the adapter port 134 gradually rotates to above the discharge hole 4 and remains connected. At this time, the previously compressed first spring 54 in the mold frame 52 quickly and elastically resets, pressing and filling the mold frame 52 with the finished product. The plastic product is elastically ejected and automatically pops out downwards along the adapter port 134 and the discharge port 4, completing high-quality cutting and automatic material ejection. After completing this single cutting and automatic material ejection, as the cutting part 5 moves upwards and resets, the control part 9 automatically moves upwards, and the air outlet 88 reconnects with the air inlet 92. At this time, air is supplied to the turbine mechanism 11 again, causing the pushing component 10 to move again and automatically push the material. After the control part 9 moves upwards, the gas in the filling and pushing component 6 bypasses along the bypass pipe 95 in the control part 9 and the bypass hole at one end of the fixed frame 62. The switching component 13 resets under the reset of the second spring 64, waiting for the next cutting.

[0046] First, by installing a rotatable switching component 13 on the top of the workbench 1, and cooperating with the downward cutting of the cutting unit 5, the rotating disk 131 is used for support during cutting, supporting the bottom of the elastic plastic and completing the cutting. During the cutting process, the cutting unit 5 automatically pushes the control unit 9 to change the ventilation direction of the distribution component 8. After the cutting is completed, the air pump 81 guides the input gas to the push component 6, so that the push component 6 rotates the switching component 13. The rotating disk 131 rotates and switches the adapter port 134 to the bottom of the cut elastic plastic product. With the push of the spring 54, the cut plastic product is automatically ejected along the adapter port 134 and the bottom of the discharge port 4, completing the automatic discharge. Thus, when dealing with elastic plastic products, by rotating the rotating disk 131 which intermittently supports and opens, the coordination of support and rapid discharge is achieved. It can achieve rapid automatic discharge while providing stable support for elastic plastic products, greatly expanding the application range of cutting plastic products of different properties.

[0047] Furthermore, by utilizing the ventilation of the distribution component 8, and in conjunction with the arrangement and connection of the turbine mechanism 11 and the pusher component 10, the air pump 81 in the distribution component 8 is started before the pressure cutting begins, thereby driving the turbine mechanism 11 and enabling the pusher component 10 to automatically feed the plastic product. When the pressure cutting action occurs, the control unit 9 is moved downward by the pressure cutting part, changing the ventilation direction of the air pump 81. Without stopping the start of the air pump 81, the gas is directly guided to the pusher component 6 through the control unit 9, and the rotation of the switching component 13 is completed. Thus, the entire continuous process of feeding and pressure cutting is completed. In this process, the air pump 81, which provides the power source for feeding, never needs to be stopped, and there is no need to add electrical equipment to control its start-up. After the pressing and cutting is completed, the air pump 81 changes the airflow direction again to start the next round of automatic feeding. This avoids the frequent start-stop of the existing feeding power source, reduces the risk of power source failure, and makes the pressing and cutting process simple and automatic. The power source operates stably. In addition to serving as the feeding power source, the air pump 81 also provides power for the rotation of the switching component 13 through the reversing airflow effect, realizing the pressing and cutting of elastic plastic products and automatic discharge. There is no need to add an additional power source, and continuous pressing and cutting does not require frequent start-stop.

[0048] Second embodiment: When processing rigid plastic products, as the plastic product is placed at the cutting position, before the cutting process, the control part 9 can be manually pressed frequently to make the first blind hole 93 and the bypass pipe 9 intermittently connected to the pushing component 6, thereby causing the gas to intermittently push the switching component 13 to rotate, so that the rotating disk 131 with a frosted surface on the top repeatedly rotates and rubs along the bottom of the rigid plastic product to be cut, completing the grinding process.

[0049] First, by utilizing the air supply from the air pump 81 again, and in conjunction with the manual up-and-down movement of the control unit 9, gas is intermittently introduced into the push assembly 6. This enables the intermittent rotation of the switching assembly 13 in the early stage of pressing and cutting, in conjunction with the reciprocating rotation of the rotating plate 131. The frosted surface on the top of the rotating plate 131 is used to polish the rigid plastic product before pressing and cutting, thus meeting the processing needs of more comprehensive plastic products. This provides more comprehensive functions, further reduces subsequent processing steps for rigid plastic products, and results in better processing effects.

[0050] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, the top of the workbench 1 is provided with an adapter groove 3, which is connected to the discharge hole 4. The inner surface of the adapter groove 3 is rotatably sleeved with the rotating disk 131. The rotating shaft 132 is rotatably sleeved in the workbench 1. The first gear 133 is located below the workbench 1. The adapter port 134 is opened on the top of the rotating disk 131. The size of the adapter port 134 is larger than the size of the discharge hole 4. Both the discharge hole 4 and the adapter port 134 are located on the outer side of the axis of the rotating shaft 132.

[0051] By utilizing the adapter groove 3 in conjunction with the rotation of the rotating disk 131, and with the adapter port 134 intermittently communicating with the discharge hole 4 during rotation and reset, material discharge is completed when the connection is established, and support is provided when the connection is not established.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, the top plate 51 is fixedly connected to the movable end of the power arm 2, the mold frame 52 is fixedly connected to the bottom surface of the top plate 51, the reserved plate 53 is movably sleeved in the mold frame 52, the first spring 54 is fixedly connected to the bottom surface of the top plate 51 and is fixedly connected to the reserved plate 53, the horizontal plate 55 is fixedly connected to the side of the top plate 51, the push rod 56 is fixedly connected to the bottom surface of the horizontal plate 55, the mold frame 52 is located directly above the discharge hole 4, and the bottom surface of the reserved plate 53 is located above the bottom surface of the mold frame 52.

[0053] The pressing and cutting action is completed by the pressing and cutting part 5. The power arm 2 provides downward power. The first spring 54 stores elastic potential energy. On the one hand, it works with the reserved plate 53 to provide support and buffer during the pressing and cutting of elastic plastic products. On the other hand, it is used to automatically eject the molded plastic products when the bottom is opened. The bottom of the push rod 56 is slightly lower than the bottom of the mold frame 52, which makes it easier to make the control part 9 descend in advance, so as to realize the automatic control of the reversal of the ventilation direction of the distribution component 8.

[0054] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 11As shown, the fixed frame 62 is fixedly connected to the bottom surface of the workbench 1. One end of the movable rod 63 is movably sleeved inside the fixed frame 62, and the other end of the movable rod 63 is fixedly connected to the toothed plate 61. The toothed plate 61 is meshed with the first gear 133. One end of the second spring 64 is fixedly connected to one end of the toothed plate 61, and the other end of the second spring 64 is fixedly connected to the end face of the fixed frame 62. The slide rod 65 is fixedly connected to the top surface of the toothed plate 61. The bottom surface of the workbench 1 is provided with a slide groove 14. The inner surface of the slide groove 14 is fixedly sleeved with a limit block 15. The inner surface of the slide groove 14 is slidably sleeved with the slide rod 65. The limit block 15 is located on the side close to the second spring 64 and is in contact with one end of the slide rod 65.

[0055] By utilizing the pushing component 6 to complete the pushing rotation and elastic automatic reset of the switching component 13, the switching action of the adapter port 134 in the switching component 13 is realized, thereby completing the control of support and material discharge. The elasticity of the second spring 64 facilitates reset. The slide rod 65 cooperates with the slide groove 14 to maintain stable sliding. The limit block 15 maintains the initial position stability. The movable rod 63 bears the pneumatic thrust in the fixed frame 62.

[0056] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a support frame 7 is fixedly connected to the bottom of the workbench 1. An air pump 81 is fixedly installed on the top of the support frame 7. The distribution frame 82 is fixedly connected to and communicates with the fixed frame 62. The intermediate pipe 85 is fixedly connected between the distribution frame 82 and the air pump 81.

The third spring 86 is fixedly connected inside the second sleeve 84. The lower end of the movable column 91 passes through the first sleeve 83 and the distribution frame 82 and is sleeved inside the second sleeve 84 and fixedly connected to the third spring 86. One end of the connecting pipe 12 is fixedly connected to the distribution frame 82 and communicates with one end of the air outlet 88. The other end of the air outlet 88 is connected to the intermediate pipe 85. The distribution assembly 8 also includes an internal cavity 87, an air outlet 88, and a sleeve interface 89. The internal cavity 87 is opened inside the distribution frame 82. The air outlet 88 and the sleeve interface 89 are opened on the distribution frame 82. The front, back, sides, and top, the internal cavity 87, and the vent 88 are connected to each other through the sleeve interface 89. The upper and lower parts of the sleeve interface 89 are connected to the first sleeve 83 and the second sleeve 84, respectively. The lower part of the movable column 91 is movably sleeved in the sleeve interface 89. The vent 92 passes through the front of the movable column 91. The bypass pipe 95 is fixedly sleeved inside the movable column 91 and passes through both sides of the movable column 91. The first blind hole 93 and the second blind hole 94 are respectively opened on the front and side of the movable column 91 and are connected to each other. The first blind hole 93 and the second blind hole 94 are both located above the vent 92. The movable column 91 is located directly below the push rod 56. One end of the connecting pipe 12 is fixedly connected to the distribution frame 82 and connected to one end of the vent 88. The other end of the vent 88 is connected to the intermediate pipe 85. A bypass hole is opened at the front end of the distribution frame 82. The bypass hole is located on the moving trajectory of the bypass pipe 95.

[0057] The distribution component 8 provides pneumatic power and works with the control unit 9 to switch the ventilation direction. The first sleeve 83 and the second sleeve 84 adapt to the up and down movement of the movable column 91. After the first blind hole 93 and the second blind hole 94 are connected and descend, they are connected to the intermediate pipe 85 to complete the pushing of the pushing component 6. When the vent 92 is connected to the intermediate pipe 85, the initial gas is guided out and prepared for automatic feeding. The bypass pipe 95 and the bypass hole are intermittently connected, and the previously introduced gas is automatically discharged when connected.

[0058] like Figure 1 , Figure 2 , Figure 12 and Figure 13As shown, the feeding assembly 10 includes an assembly frame 101, a guide port 102, a feeding roller 103, and a second gear 104. The assembly frame 101 is fixedly sleeved on the top of the worktable 1. The guide port 102 is opened on the side of the assembly frame 101. The bottom of the guide port 102 is level with the top surface of the worktable 1. The feeding roller 103 is rotatably sleeved inside the assembly frame 101. There are two feeding rollers 103, which are symmetrically distributed vertically. The second gear 104 is fixedly sleeved on the inner shaft of the feeding roller 103. The shaft end of one feeding roller 103 is fixedly connected to the output shaft of the turbine mechanism 11.

[0059] By utilizing the air guide of the initial distribution component 8 and the connecting pipe 12, the gas is guided to the turbine mechanism 11. The high-speed airflow drives the turbine mechanism 11 to rotate, thereby realizing the rotation of a pusher roller 103. With the meshing of two second gears 104, the pusher roller 103, which rotates up and down simultaneously, is used to push the material.

[0060] The working principle and usage process of this invention: Before the pressure cutting process, the elastic plastic is passed through the guide port 102 of the pusher assembly 10. Before the pressure cutting action, the distribution assembly 8 is started, and the air pump 81 guides the initially blown gas through the air outlet 88 and the connecting pipe 12 to the turbine mechanism 11. Under the blowing of the high-speed airflow, the turbine mechanism 11 drives the single pusher roller 103 to rotate. With the meshing and rotation of the two second gears 104, the upper and lower distributed pusher rollers 103 rotate simultaneously and push the plastic forward along the upper and lower surfaces. When the elastic plastic product moves to the position to be pressure cut, the power arm 2 is started, so that the pressure cutting part 5 moves downward. The mold frame 52 first contacts the top surface of the plastic and performs the initial cut. As the mold frame 52 continues to descend and cut, the cut plastic... The plastic product gradually fills the interior of the mold frame 52, pushing the reserved plate 53 upward and compressing the first spring 54. The cut plastic product is completely cut off. As the cutting part 5 descends to cut, the push rod 56 contacts the control part 9 before cutting begins, and further pushes the control part 9 downward along the interior of the first sleeve 83 and the second sleeve 84 during the cutting process. As the movable column 91 is pushed downward during the cutting process, the vent 92 gradually descends and is offset from the air outlet 88. At the same time, the first blind hole 93 is connected to the air outlet 88. At this time, the air output of the air pump 81 is directly guided to the internal cavity 87 of the distribution frame 82 through the first blind hole 93 and the second blind hole 94, and continuously fills the fixed frame 62 of the pushing assembly 6. The pressurized gas in the fixed frame 62 Pushing the movable rod 63 to move laterally, as the second spring 64 stretches, the toothed plate 61 gradually moves laterally and drives the meshing first gear 133 to rotate, causing the rotating shaft 132 to drive the rotating disk 131 to rotate. As the rotating disk 131 rotates at the bottom of the mold frame 52, the adapter port 134 gradually rotates to the top of the discharge hole 4 and remains connected. At this time, the first spring 54, which was previously compressed in the mold frame 52, quickly and elastically resets, elastically pushing out the molded plastic product that has been cut and filled in the mold frame 52, and automatically ejecting it downwards along the adapter port 134 and the discharge hole 4, completing high-quality cutting and automatic material ejection. After completing this single cutting and automatic material ejection, as the cutting part 5 moves upwards and resets, the control part 9 automatically moves upwards, and the vent 88 reconnects with the vent 92. Air is reintroduced into the turbine mechanism 11, causing the pusher assembly 10 to operate again and automatically push the material. After the control unit 9 moves upward, the gas in the filling and pushing assembly 6 bypasses along the bypass pipe 95 in the control unit 9 and the bypass hole at one end of the fixed frame 62. The switching assembly 13 is reset under the reset of the second spring 64, waiting for the next pressing and cutting. When processing rigid plastic products, as the plastic product is placed at the pressing and cutting position, before the pressing and cutting process, the control unit 9 can be manually pressed frequently to make the first blind hole 93 and the bypass pipe 9 intermittently connect with the pushing assembly 6, thereby causing the gas to intermittently push the switching assembly 13 to rotate, so that the rotating disk 131 with a frosted surface on the top repeatedly rotates and rubs along the bottom of the rigid plastic product to be cut, completing the grinding process.
