Description

Technical Field

[0001] This invention belongs to the field of plastic recycling and packaging product manufacturing technology, specifically relating to a processing equipment for jewelry boxes based on the recycling of plastic waste. Background Technology

[0002] Currently, plastic products are widely used in packaging, daily necessities, industrial processing, and many other fields due to their advantages such as light weight, low cost, and good formability. With the continuous expansion of plastic product production capacity, a large amount of plastic scraps, waste plastic parts, and household waste plastics are generated during the production and processing process. If such plastic waste is directly landfilled or incinerated, it will not only occupy land resources but also generate harmful pollutants, causing soil and air pollution, which is inconsistent with the current green, low-carbon, and circular production development concept. At the same time, jewelry boxes are a common product for jewelry storage and packaging, with a large market demand. Existing jewelry boxes are mostly made of new plastic, wood, or metal materials, which have high raw material costs. Wood materials also suffer from logging losses, resulting in a large consumption of resources. However, using recycled waste plastics to make jewelry boxes can effectively reduce production costs, realize the resource reuse of waste materials, and have good economic and environmental value.

[0003] CN220841502U discloses a jewelry box pressing device, including a jewelry box pressing device body and a control box. A support base is fixedly installed at the bottom of the jewelry box pressing device body, a jewelry box fixing clamp is installed at the top of the jewelry box pressing device body, a connecting slider is fixedly installed at the bottom of the jewelry box fixing clamp, a horizontal moving block is fixedly installed at the bottom of the connecting slider, and an anti-contact spring is installed on the side of the horizontal moving block.

[0004] The aforementioned application document describes a method for clamping and fixing the jewelry box on both sides using a combination of a push block, a push plate, a fixing clamp, and a spring. However, this method can only achieve unidirectional clamping on both sides, which may cause the sheet material to shift back and forth during pressing. Summary of the Invention

[0008] Furthermore, a guide groove B is provided on the inner side of the clamping plate A, and a slider B is fixedly connected to the inner side of the clamping plate B, with the slider B slidably connected inside the guide groove B.

[0009] Furthermore, a torsion spring A is fixedly connected to the bottom inner wall of the receiving groove, and the other end of the torsion spring A is fixedly connected to the bottom of the V-shaped rod.

[0010] Furthermore, a mounting plate is fixedly connected to the upper end of the workbench. Two transmission cylinders are rotatably connected to the inner side of the mounting plate. A transmission belt is wound around the outer wall of the two transmission cylinders. A linkage shaft is rotatably connected to the side of the lifting platform. A connecting rod B is rotatably connected to the other end of the linkage shaft. A moving block is hinged to the other end of the connecting rod B. A moving rod A is fixedly connected to the outer wall of the moving block. A track groove is opened on the outer wall of the moving rod A. A ratchet is rotatably connected to the inner side of the mounting plate. A sliding shaft C is fixedly connected to the inner side of the ratchet. A mounting block is fixedly connected to the inner side of one of the transmission cylinders. A pawl is rotatably connected to the inner side of the mounting block through a pin. A torsion spring B is fixedly connected between the mounting block and the pawl.

[0011] Furthermore, the track groove is configured as a spiral groove and a straight groove, with the straight groove located on the side away from the mounting plate, and the sliding shaft C is slidably connected inside the track groove.

[0012] Furthermore, a guide rail is fixedly connected to the upper end of the workbench, and the moving block is slidably connected to the outer wall of the guide rail.

[0013] Furthermore, a horizontal plate is fixedly connected to the outer side of the mounting plate. A mounting groove is formed on the side of the horizontal plate away from the mounting plate. A movable plate is hinged to the inner side of the mounting groove via a pin. A movable groove is formed on the upper side of the movable plate. Sliding grooves B are formed on both sides of the movable groove. A fixed block B is fixedly connected to the upper end of the mounting plate. A moving rod B slides through the middle of the fixed block B. A push plate is fixedly connected to the inner end of the moving rod B. Sliding shafts D are rotatably connected to both sides of the moving rod B. The sliding shafts D are slidably connected inside the sliding grooves B.

[0014] Furthermore, a fixing ring is fixedly sleeved on the outer wall of the moving rod B, and a spring is fixedly connected between the fixing block B and the fixing ring.

[0015] The advantages of this application are: (1) This application uses a motor to drive the movable rod and connecting rod A to drive the V-shaped rod to slide, so that the V-shaped rod first drives the clamping plate A to move towards the middle to complete the initial alignment and clamping of the plastic recycled sheet; when the clamping plate A contacts the sheet, the V-shaped rod continues to rotate to compress the torsion spring, and at the same time pushes the clamping plate B to slide inward through the sliding shaft B and connecting rod, so that the other side of the sheet contacts the limiting plate to complete the secondary clamping, thereby achieving comprehensive positioning and fixing of the raw material sheet around the perimeter, avoiding displacement of the sheet during hot pressing, and ensuring the processing accuracy and molding quality of the jewelry box blank.

[0016] (2) This application utilizes the lifting action of the lifting platform, and drives the moving block to slide back and forth along the slide rail through the linkage shaft and connecting rod B. The track groove on the moving rod A cooperates with the sliding shaft C to drive the ratchet and pawl to drive the transmission cylinder to rotate in one direction. This allows the transmission belt to automatically convey a section of raw material after each pressure plate rises. The setting of the straight groove section in the track groove provides sufficient delay for the push plate to reset, ensuring that the conveying action and the pushing action do not interfere with each other. This realizes the automatic step feeding of raw materials, which greatly improves the processing efficiency and automation level.

[0017] (3) In this application, a movable rod is set on the movable rod A. Through the linkage between the movable plate and the slide B, the forward and backward extension of the movable rod B and the push plate are controlled. When the movable rod A moves outward, the movable rod leaves the lower side of the movable plate, and the push plate automatically retreats to avoid the feeding area under the assistance of gravity and spring. When the movable rod A is reset, the movable rod lifts the movable plate, and the push plate automatically extends forward under the assistance of spring, accurately pushing the raw material on the transmission belt to the processing position and aligning it with the limit plate.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-6 As shown, a jewelry box processing equipment based on plastic waste recycling includes a workbench 1, a support leg 2 fixedly connected to the bottom of the workbench 1, a fixed plate 3 fixedly connected to the upper end of the support leg 2, an electric slide rail 4 mounted on the inner side of the fixed plate 3, a lifting platform 5 slidably connected to the outer wall of the electric slide rail 4, a pressure plate 6 mounted on the bottom of the lifting platform 5, an L-shaped plate 10 provided on the side of the workbench 1, and a recycling device 11 for heating and molding plastic waste mounted on the upper end of the L-shaped plate 10. The discharge port of the recycling device 11 is located on the upper side of the workbench 1. A motor 71 is fixedly connected to the bottom of the workbench 1. A movable rod A72 is fixedly connected to the output shaft of the motor 71. Connecting rods A73 are rotatably connected to both ends of the movable rod A72 via pins. A connecting shaft 74 is rotatably connected to the other end of the connecting rod A73. A U-shaped rod 75 is rotatably connected to the upper end of the connecting shaft 74. A sliding shaft A76 is rotatably connected to the upper side of the other end of the U-shaped rod 75. A clamping plate A77 is provided at the upper end of the workbench 1. A receiving groove 78 is opened at one end of the clamping plate A77. A mounting shaft 79 is rotatably connected inside the receiving groove 78. A V-shaped rod 710 is fixedly sleeved on the outer wall of 79. Sliding grooves A721 are symmetrically opened on both sides of the V-shaped rod 710. The sliding shafts A721 and B711 slide freely in the corresponding sliding grooves A721 along the length direction. A connecting rod 712 is movably sleeved on the outer wall of the sliding shaft B711. A clamping plate B713 is fixedly connected to the other end of the connecting rod 712. A fixing block A719 is fixedly connected to the upper end of the worktable 1. The upper end of the C-shaped rod 75 slides through the fixing block A719. A limit plate 720 is fixedly connected to the upper end of the worktable 1.

[0022] The upper end of the workbench 1 is provided with a guide groove A714, and the bottom of the clamping plate A77 is fixedly connected with a slider A715. The slider A715 is slidably connected inside the guide groove A714. Thus, when the motor 71 drives the V-shaped rod 710 to move the clamping plate A77, the slider A715 slides linearly along the guide groove A714, accurately guiding the movement direction of the clamping plate A77, preventing the clamping plate A77 from deflecting or getting stuck during the movement, and ensuring that the clamping plates A77 on both sides can move towards the middle smoothly and symmetrically, so as to achieve precise alignment and clamping of the raw material plate.

[0023] A guide groove B716 is provided on the inner side of the clamping plate A77. A slider B717 is fixedly connected to the inner side of the clamping plate B713. The slider B717 is slidably connected inside the guide groove B716. The slider B717 slides along the guide groove B716 to provide stable linear motion guidance for the clamping plate B713, ensuring that the clamping plate B713 can apply pressure perpendicular to the side of the plate.

[0024] A torsion spring A718 is fixedly connected to the bottom inner wall of the receiving groove 78. The other end of the torsion spring A718 is fixedly connected to the bottom of the V-shaped rod 710. The torsion spring A718 is set to assist the V-shaped rod 710 to quickly reset after processing, so that the clamping plate A77 and the clamping plate B713 can release the workpiece synchronously, thereby improving the reset sensitivity and response speed.

[0025] In practical use, the aforementioned equipment involves feeding plastic waste into the recycling equipment 11, where it is then heated and molded into raw material sheets. These sheets fall onto the upper end of the transmission belt 83. The raw material sheets are then pushed to the upper end of the worktable 1 by the push plate 98. The starting motor 71 drives the movable rod A72 to rotate. The movable rod A72, through the connecting rods A73 on both sides, pulls the connecting shaft 74 inward, thereby causing the chamfered rod 75 to slide inward inside the fixed block A719. When the clamping plate A77 is not in contact with the side of the sheet, the chamfered rod 75 moves the V-shaped rod 710 through the sliding shaft A76, which in turn moves the clamping plates A77 on both sides towards the center through the mounting shaft 79, until the raw material sheet is initially aligned and clamped. When the clamping plate A77 contacts the side of the raw material sheet... After contact, since the clamping plate A77 can no longer move, the sliding shaft A76 continues to drive the V-shaped rod 710 to rotate around the mounting shaft 79. While compressing the torsion spring A718, the V-shaped rod 710 will push the sliding shaft B711 towards the mounting plate 81 through the sliding groove A721 on the other side. This will drive the connecting rod 712 to push the clamping plate B713 to slide inward along the guide groove B716. As a result, the clamping plate B713 will contact the other side of the material, causing the side of the material away from the clamping plate B713 to contact the limiting plate 720. This allows the clamping plate B713 to apply pressure and clamp the material from the other end. Together with the clamping plates A77 on both sides, the material is positioned and fixed around its perimeter, preventing displacement during subsequent pressing and ensuring processing accuracy. After clamping, the electric slide rail 4 drives the lifting platform 5 to move downward, which in turn drives the pressure plate 6 to press down, hot-pressing the stacked recycled plastic raw material sheets to form the jewelry box blank. After processing, the lifting platform 5 drives the pressure plate 6 to rise, and the motor 71 rotates in the opposite direction, releasing the clamping of the processed raw material sheets. The formed jewelry box blank can then be taken out, completing the processing.

[0026] Example 2, as Figures 3-7 As shown, based on Embodiment 1, a mounting plate 81 is fixedly connected to the upper end of the workbench 1. Two transmission cylinders 82 are rotatably connected to the inner side of the mounting plate 81. A transmission belt 83 is wound around the outer wall of the two transmission cylinders 82. A linkage shaft 84 is rotatably connected to the side of the lifting platform 5. A connecting rod B85 is rotatably connected to the other end of the linkage shaft 84. A moving block 86 is hinged to the other end of the connecting rod B85. A moving rod A87 is fixedly connected to the outer wall of the moving block 86. A track groove 88 is opened on the outer wall of the moving rod A87. A ratchet 89 is rotatably connected to the inner side of the mounting plate 81. A sliding shaft C810 is fixedly connected to the inner side of the ratchet 89. A mounting block 811 is fixedly connected to the inner side of one transmission cylinder 82. A pawl 812 is rotatably connected to the inner side of the mounting block 811 through a pin. A torsion spring B813 is fixedly connected between the mounting block 811 and the pawl 812.

[0027] The track groove 88 is configured as a spiral groove and a straight groove, with the straight groove located on the side away from the mounting plate 81. The sliding shaft C810 is slidably connected inside the track groove 88. The combination of the spiral groove and the straight groove in the track groove 88 provides a delay for the push plate 98 to reset, ensuring that the drive belt 83 only starts feeding after the push plate 98 has completely exited the feeding area, thus avoiding interference.

[0028] The upper end of the worktable 1 is fixedly connected to the guide rail 814, and the moving block 86 is slidably connected to the outer wall of the guide rail 814. The guide rail 814 guides the moving direction of the moving block 86, ensuring that the moving rod A87 moves stably along a straight line and avoids jamming or wear between the sliding shaft C810 and the track groove 88.

[0029] When the above equipment is used, when the electric slide rail 4 drives the lifting platform 5 to rise, it will drive the linkage shaft 84 to rise accordingly. The linkage shaft 84 pulls the moving block 86 along the guide rail 814 away from the mounting plate 81 through the connecting rod B85. At this time, the moving rod A87 moves synchronously. Since the slide shaft C810 slides inside the track groove 88, when the slide shaft C810 slides through the straight groove part and enters the spiral groove part, it pushes the slide shaft C810 to drive the ratchet 89 to rotate a certain angle. At this time, the pawl 812 drives the transmission cylinder 82 to rotate synchronously, thereby driving the transmission belt 83 to run, and conveying the plastic waste raw material to be processed placed on the transmission belt 83 forward a certain distance. When the electric slide rail 4 drives the lifting platform 5 to descend, the linkage shaft 84 descends accordingly. Through the connecting rod B85, the moving block 86 slides along the guide rail 814 towards the mounting plate 81 to reset. At this time, the slide shaft C810 slides in the opposite direction along the track groove 88, returning from the spiral groove to the straight groove. During this process, the ratchet 89 will not drive the transmission cylinder 82 through the pawl 812, and the transmission belt 83 will stop conveying. This enables the lifting platform 5 to automatically convey a section of raw material after each lifting and processing, eliminating the need for manual repeated feeding and position adjustment, and improving the automation level of processing. The linear groove in the track groove 88 provides sufficient time for the pusher plate 98 to push the material, ensuring that when the lifting platform 5 rises, the pusher plate 98 returns to a position that does not obstruct the material feeding of the transmission belt 83 before transmission.

[0030] Example 3, as Figure 8As shown, based on Embodiment 1 or Embodiment 2, a horizontal plate 91 is fixedly connected to the outer side of the mounting plate 81. A mounting groove 92 is provided on the side of the horizontal plate 91 away from the mounting plate 81. A movable plate 93 is hinged to the inner side of the mounting groove 92 by a pin. A movable groove 94 is provided on the upper side of the movable plate 93. Sliding grooves B95 are provided on both sides of the movable groove 94. A fixed block B96 is fixedly connected to the upper end of the mounting plate 81. A moving rod B97 slides through the middle of the fixed block B96. A push plate 98 is fixedly connected to the inner end of the moving rod B97. The highest point of the push plate 98 is lower than the lowest surface of the pressure plate to avoid motion interference between the push plate and the pressure plate. Sliding shafts D99 are rotatably connected to both sides of the moving rod B97. The sliding shafts D99 are slidably connected inside the sliding grooves B95. A movable rod B912 is fixedly connected to the end of the moving rod A87 away from the moving block 86. The movable rod B912 will contact the lower side of the movable plate 93 during the movement.

[0031] A fixing ring 911 is fixedly sleeved on the outer wall of the moving rod B97. A spring 910 is fixedly connected between the fixing block B96 and the fixing ring 911. The spring 910 is designed to assist in pushing the push plate 98 forward to ensure that the material is pushed into place. On the other hand, it plays a buffering role when the push plate 98 retracts, reducing impact and improving the smoothness of the operation.

[0032] In practical use, when the moving rod A87 moves towards the center of the worktable 1, the movable rod B912 moves synchronously and gradually moves away from the lower side of the movable plate 93. At this time, the movable plate 93 loses its upward support and rotates downward around the hinge axis under the action of gravity and spring 910. The sliding grooves B95 on both sides of the movable groove 94 then drive the sliding shaft D99 to move away from the transmission belt 83, thereby pulling the moving rod B97 and the push plate 98 backward to compress the spring 910, so that the push plate 98 exits the feeding area of ​​the transmission belt 83 and does not obstruct the conveying of raw materials. The conveying action: When the moving rod A87 moves outward, the movable rod B912 moves synchronously, and its front end abuts against the lower side of the movable plate 93, lifting the movable plate 93 upward. The movable plate 93 rotates, causing the slide groove B95 to push the slide shaft D99 in the opposite direction, which in turn pushes the moving rod B97 and the push plate 98 to extend towards the direction close to the transmission belt 83. The spring 910 then extends and resets. After the push plate 98 extends, it pushes the raw material conveyed on the transmission belt 83 to the processing position, avoiding the misalignment of the raw material conveying and affecting the subsequent processing accuracy, and further improving the automation and accuracy level of the equipment processing.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
