Description

Technical Field

[0001] This utility model relates to the field of tableware processing technology, specifically to a device for processing environmentally friendly bamboo leaf tableware. Background Technology

[0002] Bamboo leaves, as a natural material, possess many characteristics suitable for making tableware. They contain a large amount of chlorophyll and various amino acids that are beneficial to the human body, and have a natural fragrance. When food is served in tableware made of bamboo leaves, it emits a natural aroma. Moreover, bamboo leaf tableware is biodegradable, making it a natural, environmentally friendly, and practical tableware manufacturing material. Bamboo leaf tableware is usually processed using molding technology. The processing technology uses bamboo fiber as the base material, which is mixed with bio-based polymers, adhesives, etc., and pressed into an environmentally friendly sheet. The sheet is then molded using a heated mold to form bamboo leaf tableware.

[0003] However, the existing technology has the following problems:

[0004] In existing technology, before molding, the rolled sheet material needs to be cut into multiple segments. During molding, the operator manually places a segment of sheet material on the mold. After molding, the formed bamboo leaf tableware and the waste sheet material on its edges are separated. After the formed bamboo leaf tableware is ejected by the ejection mechanism of the mold, the operator still needs to remove the waste sheet material and manually place the next segment of sheet material. Manual operation is cumbersome and has low work efficiency. In addition, because the temperature of the mold is high, manually placing the sheet material may burn the hands. Utility Model Content

[0016] The beneficial effects are:

[0017] 1.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Example 1

[0038] Please see Figure 1 - Figure 2 An environmentally friendly bamboo leaf tableware processing device includes an operating table 1, an mounting platform 2 installed on the operating table 1, four sliding columns 3 connected to the mounting platform 2, a fixing plate 4 connected to the top of the four sliding columns 3, a hydraulic cylinder mounted on the fixing plate 4, a pressure plate 5 slidably connected to the outer wall of the four sliding columns 3, the pressure plate 5 connected to the output end of the hydraulic cylinder, an upper mold 11 connected to the bottom surface of the pressure plate 5, and a lower mold 12 connected to the top surface of the mounting platform 2. The operating table 1, mounting platform 2, sliding columns 3, fixing plate 4, pressure plate 5, upper mold 11, and lower mold 12 constitute a conventional molding machine. The device is existing technology, and its specific structure and working principle will not be described in detail. The upper mold 11 and the lower mold 12 have a preheating device, a cooling device, a trimming device, and an ejection device. The hydraulic cylinder is activated, which causes the pressure plate 5 to move the upper mold 11 downward to realize the molding operation. There are multiple cavities between the upper mold 11 and the lower mold 12. Each molding can process multiple bamboo leaf tableware. After molding, the multiple bamboo leaf tableware are trimmed by the trimming device to separate the waste sheet material from the bamboo leaf tableware. After the bamboo leaf tableware is ejected by the ejection device, the operator uses the unloading clamp to take it out.

[0039] Furthermore, please refer to Figure 1 - Figure 6 It also includes: a traction device 6, used to pull the rolled sheet material onto the lower die 12 for processing; the traction device 6 includes a slide 62, which is slidably mounted on the mounting platform 2. A connecting rod 61 is hinged to the slide 62, and the end of the connecting rod 61 away from the slide 62 is hinged to the pressure plate 5. When the pressure plate 5 moves down, it drives the slide 62 to move to the right through the connecting rod 61. When the pressure plate 5 moves up, it drives the slide 62 to move to the left through the connecting rod 61. An upper clamping block 63 is fixedly mounted on the slide 62, and connecting blocks 64 are connected to both sides of the upper clamping block 63. The connecting blocks 64 are slidably connected to... There is a first slider 65, and a first sliding shaft 66 is fixedly connected to the first slider 65. A lower clamping block 67 is fixedly connected between the two first sliders 65. Two slotted plates 68 are fixedly installed on the mounting platform 2. The lower clamping block 67 is located below the upper clamping block 63. The slotted plates 68 are provided with parallelogram sliding grooves. The two first sliding shafts 66 are slidably connected to the parallelogram sliding grooves of the two slotted plates 68 respectively. When the lower clamping block 67 moves from left to right, the lower clamping block 67 maintains a clamping force with the upper clamping block 63. When the lower clamping block 67 is about to move to the right... When in position, the two first sliding shafts 66 drive the lower clamping block 67 to move downwards, causing the lower clamping block 67 and the upper clamping block 63 to lose their clamping force. When the lower clamping block 67 moves from right to left, the lower clamping block 67 and the upper clamping block 63 remain open. When the lower clamping block 67 is about to move to the left position, the two first sliding shafts 66 drive the lower clamping block 67 to move upwards, causing the lower clamping block 67 and the upper clamping block 63 to clamp again. When the pressure plate 5 drives the upper mold 11 to move upwards, the slide 62 moves to the left, and the upper clamping block 63 gradually moves to above the right edge of the sheet. The lower clamping block 67 moves to the lower edge of the right edge of the sheet. As the platen 5 gradually moves upward, the lower clamping block 67 and the upper clamping block 63 eventually clamp the sheet. When the pressure plate 5 moves downward again, the lower clamping block 67 and the upper clamping block 63 can pull the sheet to the right. Through the setting of the traction device 6, the lower clamping block 67, in cooperation with the upper clamping block 63, pulls the sheet each time the upper mold 11 moves downward, so that the next section of sheet covers the lower mold 12, and the waste sheet is removed from the lower mold 12. This achieves the effect of automated traction, eliminates the manual operation of laying the sheet, improves work efficiency, and also improves the safety during operation.

[0040] Furthermore, please refer to Figure 2 - Figure 3A drum 9 is rotatably mounted on the operating table 1 via a bracket. The drum 9 and the slide 62 are located on both sides of the lower die 12. Two tension rollers 10 are rotatably mounted on the operating table 1 via a bracket. The two tension rollers 10 are located between the drum 9 and the lower die 12. The rolled sheet is mounted on the drum 9. One end of the sheet is pulled out, passes through the two tension rollers 10, and then pulled to the right. The two tension rollers 10 have a certain degree of flexibility and can form a certain clamping force on the sheet to maintain the tension of the sheet when it is pulled. By setting the two tension rollers 10, the two tension rollers 10 can tension the sheet when it is pulled, thus preventing the sheet from wrinkling.

[0041] In addition, please see Figure 1 , Figure 7 - Figure 9 Waste recycling device 7 is used to collect and stack sheet waste after cutting; waste recycling device 7 includes mounting box 71 and collection box 72. Mounting box 71 is fixedly mounted on mounting platform 2, and collection box 72 is slidably mounted inside mounting box 71. Collection box 72 is located below the movement trajectory of slide 62. Collection box 72 is used to collect sheet waste. Collection box 72 is similar to a drawer installed inside mounting box 71 and can be pulled out for easy handling of sheet waste.

[0042] In addition, please see Figure 7 - Figure 10The waste recycling device 7 also includes two pry bars 73, a crossbar 74, two second sliding shafts 75, two second sliders 76, a cutter 77, and a stop bar 713. The two pry bars 73 are rotatably mounted on both sides of the mounting box 71. The crossbar 74 is fixedly connected to the slide frame 62. One end of each pry bar 73 has a sliding groove, and the other end is located on the movement trajectory of the crossbar 74. The two second sliders 76 are slidably connected to both sides of the mounting box 71. The two second sliding shafts 75 are fixedly connected to the two second sliders 76, and the two second sliding shafts 75 are slidably connected to the sliding grooves of the two pry bars 73. The cutter 77 is fixedly connected between the two second sliders 76. When the crossbar 74 moves, it contacts the two pry bars 73 and drives them to rotate clockwise. The left ends of the two pry bars 73 pass through two… The sliding groove and the two second sliding shafts 75 work together to drive the two second sliders 76 to move upward. When the two second sliders 76 move upward, they drive the cutter 77 to move upward. The abutment bar 713 is fixedly connected to the two groove plates 68. The abutment bar 713 is located on the movement trajectory of the cutter 77. The abutment bar 713 is provided with a groove. The cutting edge of the cutter 77 and the groove of the abutment bar 713 form a shearing force, thereby cutting the sheet material. With the setting of the waste recycling device 7, whenever the lower clamping block 67 and the upper clamping block 63 pull the sheet waste to the right, the cutter 77 can automatically move upward and cut the sheet waste through cooperation with the abutment bar 713, so that the cut sheet waste is laid flat in the collection box 72. After being pulled and cut, the sheet waste can be stacked in the collection box 72, making the sheet waste in the collection box 72 more neat and improving the utilization rate of the storage space.

[0043] It is worth noting that, please refer to Figure 10 - Figure 12 The waste recycling device 7 also includes two slide plates 78 and two grinding blocks 79. The two slide plates 78 are slidably connected inside the mounting box 71. The two grinding blocks 79 are connected to the two slide plates 78 by multiple springs. The two grinding blocks 79 are in contact with the two sides of the cutter 77. The two grinding blocks 79 maintain pressure on the two sides of the cutter 77 by the elastic force of the multiple springs on the two slide plates 78. Therefore, when the cutter 77 moves up and down, the two grinding blocks 79 can continuously grind the cutter 77 to maintain its sharpness.

[0044] It is worth noting that, please refer to Figure 11 - Figure 12The waste recycling device 7 also includes two corrugated strips 710, two leaf springs 711, and two deflector shafts 712. The two corrugated strips 710 are respectively fixedly connected to one side of the two slide plates 78, and the two leaf springs 711 are respectively fixedly connected to the other side of the two slide plates 78. The outer walls of the two leaf springs 711 away from the slide plates 78 abut against the inner wall of the mounting box 71. The two deflector shafts 712 are fixedly connected to the second slider 76 near the corrugated strips 710. The two deflector shafts 712 slide in contact with the two corrugated strips 710 respectively. When the deflector shafts 712 move up and down, they pass through the corrugated strips 710. Strip 710 drives the slide plate 78 to move back and forth in a small range. The two slide plates 78 drive the two grinding blocks 79 to move back and forth in a small range through multiple springs. This allows the two grinding blocks 79 to contact the sides of the cutter 77 in the longitudinal direction while also performing lateral grinding through reciprocating movement, thereby optimizing the grinding effect. By setting the two grinding blocks 79, the two grinding blocks 79 can perform horizontal reciprocating movement to grind the sides of the cutter 77 while the cutter 77 moves up and down, maintaining the sharpness of the cutter 77 and thus ensuring the cutting effect.

[0045] It is worth mentioning that you should refer to Figure 1 , Figure 13 - Figure 14 Smoothing component 8 is used to smooth stacked sheet waste. Smoothing component 8 includes a rotating shaft 81, a connecting seat 82, an elastic sheet 83, a connecting frame 84, a pressure rod 85, and two coil springs 86. The rotating shaft 81 is rotatably mounted on a slide 62. The connecting seat 82 is fixedly connected to the outer wall of the rotating shaft 81. The elastic sheet 83 is fixedly connected to the connecting seat 82. The connecting frame 84 is fixedly connected to the side wall of the lower clamping block 67. The pressure rod 85 is fixedly connected to the end of the connecting frame 84 away from the lower clamping block 67. The pressure rod 85 slides in contact with the top surface of the connecting seat 82. Coil springs 86 are fixedly connected to the outer walls of both ends of the rotating shaft 81. The ends of the two coil springs 86 away from the rotating shaft 81 are fixedly connected to the slide 62. When the pressure rod 85 moves downward, it abuts against the connecting seat 82 and drives the connecting seat 82 and the rotating shaft 81 to rotate clockwise. The connecting seat 82 drives the elastic sheet 83 to swing downward. After the 5th movement upwards, the rotating shaft 81 is reset by the elastic force of the two coil springs 86. After the elastic plate 83 swings downwards, it can contact the sheet waste in the collection box 72. The elastic plate 83 is elastic. When the elastic plate 83 contacts the top surface of the sheet waste, it deforms and applies a small amount of pressure to the sheet waste. During the leftward movement of the elastic plate 83, the elastic plate 83 plays a smoothing role on the sheet waste. When the lower clamping block 67 and the upper clamping block 63 pull the sheet waste to the right, the elastic plate 83 is reset and does not contact the sheet waste. Through the setting of the smoothing component 8, the elastic plate 83 can smooth the sheet waste when it enters the collection box 72, making the sheet waste stacked and collected more evenly. This avoids the increase in stacking height due to wrinkles and curling edges of some sheet waste, which would affect the amount of sheet waste collected in the collection box 72.

[0046] Using the above structure, the working principle of this case is as follows: Figure 1As a directional reference, the rolled sheet material is mounted on the roll 9. One end of the sheet material is pulled out, passed through two tension rollers 10, and then pulled to the right. The operating table 1, mounting table 2, sliding column 3, fixing plate 4, pressure plate 5, upper mold 11, and lower mold 12 form a conventional molding device, which is existing technology. Its specific structure and working principle will not be described in detail. The upper mold 11 and lower mold 12 have a preheating device, a cooling device, an edge trimming device, and an ejection device. The hydraulic cylinder is activated, causing the pressure plate 5 to move the upper mold 11 downward to realize the molding operation. There are multiple cavities between the upper mold 11 and lower mold 12. Each molding can process multiple bamboo leaf tableware. After molding, the multiple bamboo leaf tableware are trimmed by the edge trimming device to separate the waste sheet material from the bamboo leaf tableware. The bamboo leaf tableware is ejected by the ejection device. After being placed at the top, the operator uses the unloading clamp to remove it; when the pressure plate 5 moves down, it drives the slide 62 to move to the right via the connecting rod 61; when the pressure plate 5 moves up, it drives the slide 62 to move to the left via the connecting rod 61; when the slide 62 moves, it drives the upper clamping block 63 to move synchronously; when the upper clamping block 63 moves left and right, it drives the lower clamping block 67 to move left and right synchronously via the two connecting blocks 64 and the two first sliders 65; when the two first sliders 65 move left and right, they also drive the two first sliding shafts 66 to move left and right synchronously. Taking one of the first sliding shafts 66 and the groove plate 68 as an example, the parallelogram groove of the groove plate 68 has two straight sides and two inclined sides. When the first sliding shaft 66 moves from left to right, it slides on the upper straight side. When the first sliding shaft 66 is about to move to the right position, the first sliding shaft 66 enters the right inclined side and moves smoothly. The first sliding shaft 66 slides diagonally downwards along the hypotenuse. When the first sliding shaft 66 reaches its rightward position, it enters the lower straight edge. As the first sliding shaft 66 moves from right to left, it slides along the lower straight edge. Just before reaching its leftward position, the first sliding shaft 66 enters the left hypotenuse and slides diagonally upwards along the hypotenuse. When the first sliding shaft 66 reaches its leftward position, it re-enters the upper hypotenuse. The process repeats for the next rightward movement. Therefore, when the lower clamping block 67 moves from left to right, the two first sliding shafts 66 maintain a clamping force with the upper clamping block 63. When the lower clamping block 67 is about to reach its rightward position, the two first sliding shafts 66 drive the lower clamping block 67 downwards, causing it to lose its clamping force with the upper clamping block 63. When the lower clamping block 67 moves from right to left... During movement, the lower clamping block 67 and the upper clamping block 63 remain open. When the lower clamping block 67 is about to move to the left, the two first sliding shafts 66 drive the lower clamping block 67 to move upward, so that the lower clamping block 67 and the upper clamping block 63 are clamped again. When the lower clamping block 67 moves to the left, an effective clamping is formed between the lower clamping block 67 and the upper clamping block 63. At the beginning of the molding operation, after the pressure plate 5 descends a certain distance, the hydraulic cylinder is stopped first. At this time, the slide 62 and the upper clamping block 63 have moved to the right, pulling one end of the sheet to the right a certain distance, so that the right edge of the sheet is on the movement trajectory of the lower clamping block 67. The sheet has a certain toughness, and its protruding edge can maintain a slightly horizontal state. Then, the normal molding operation is carried out. After the upper mold 11 is pressed down for the first time, the pressure plate 5 drives the upper mold 11 to move upward and reset.As the carriage 62 moves to the left, the upper clamping block 63 gradually moves to above the right edge of the sheet, while the lower clamping block 67 gradually moves upward as it moves below the right edge of the sheet. Finally, the lower clamping block 67 and the upper clamping block 63 clamp the sheet. When the pressure plate 5 moves downward again, the lower clamping block 67 and the upper clamping block 63 pull the sheet to the right, causing the sheet waste to detach from above the lower mold 12. The next section of sheet is then laid on the lower mold 12. When the upper mold 11 and the lower mold 12 close, the lower clamping block 67 moves downward to release the sheet. When the upper mold 11 and the lower mold 12 separate again, the lower clamping block 67 moves to the left and remains released. Subsequently, the lower clamping block 67 moves upward to clamp the sheet again. After the upper mold 11 moves downward again, the lower clamping block 67 and the upper clamping block 63 pull the sheet again. This achieves automatic sheet traction. The two tension rollers 10 have a certain degree of flexibility and can form a certain clamping force on the sheet, maintaining the tension of the sheet during traction and preventing wrinkles. Through the setting of the traction device 6, the lower clamping block 67, in cooperation with the upper clamping block 63, pulls the sheet each time the upper die 11 moves downward, causing the next section of sheet to cover the lower die 12, thus detaching the waste sheet material from the lower die 12. This achieves automated traction, eliminating the need for manual sheet laying, improving work efficiency, and enhancing operational safety. The two tension rollers 10 also tension the sheet when it is being pulled, preventing wrinkles.

[0047] The collection box 72 is used to collect sheet waste. Similar to a drawer, it is installed inside the mounting box 71 and can be pulled out for easy handling of sheet waste. When the slide 62 is about to move to its right position, the crossbar 74 on the slide 62 contacts the two pry bars 73 and drives them to rotate clockwise. Because the two second sliders 76 are limited by the mounting box 71, they can only move up and down. This causes the left ends of the two pry bars 73 to move the two second sliders 76 upwards through the cooperation of the two sliding grooves and the two second sliding shafts 75. As the two second sliders 76 move upwards, they drive the cutter 77 upwards. When the slide 62 is about to move to its right position, the cutter 77 contacts the sheet and presses it against the abutment bar 713. The abutment bar 713 has a groove, and the cutting edge of the cutter 77 is aligned with the groove of the abutment bar 713. The cutting blade 77 applies shearing force to cut the sheet. After the sheet is cut, the lower clamping block 67 moves the sheet a small distance to the right and then moves down to release the clamp, allowing the sheet to fall into the collection box 72. The right end of the pry bar 73 has an inclined section and a straight section. When the horizontal bar 74 moves to the right, it first contacts the inclined section, causing the pry bar 73 to rotate. When the pry bar 73 rotates to its final position, i.e., when the cutter 77 cuts the sheet, the horizontal bar 74 contacts the straight section of the pry bar 73. During the subsequent rightward movement of the horizontal bar 74 and its contact with the straight section of the pry bar 73, the pry bar 73 does not rotate. This allows the lower clamping block 67 and the upper clamping block 63 to continue moving the sheet a small distance to the right after the cutter 77 cuts the sheet, ensuring that the sheet falls completely into the collection box 72. After the sheet falls into the collection box 72, the lower clamping block 67 and the upper clamping block 63 move to the left, and then... The lower clamping block 67 moves upward to re-clamp the right end of the sheet being press-molded. When the crossbar 74 disengages from the two pry bars 73, the cutter 77 moves downward under its own weight, causing the two pry bars 73 to return to their original positions. The two grinding blocks 79 maintain pressure on both sides of the cutter 77 through the elastic force of multiple springs on the two sliding plates 78. Therefore, as the cutter 77 moves up and down, the two grinding blocks 79 can continuously grind the cutter 77, maintaining its sharpness. When the second slider 76, which is connected to two pivot shafts 712, moves up and down, the two pivot shafts 712 slide on the two wave strips 710 respectively. Since the pivot shafts 712 can only move up and down in a straight line, and the sliding plate 78 uses the elastic force of the leaf springs 711 to keep the wave strips 710 in contact with the pivot shafts 712, the pivot shafts 712... When moving up and down, the wave strip 710 drives the slide plate 78 to move back and forth in a small amplitude. The two slide plates 78 drive the two grinding blocks 79 to move back and forth in a small amplitude through multiple springs. This allows the two grinding blocks 79 to contact the sides of the cutter 77 in the longitudinal direction while also performing transverse grinding through reciprocating movement, thereby optimizing the grinding effect. With the setting of the waste recycling device 7, whenever the lower clamping block 67 and the upper clamping block 63 pull the sheet waste to the right, the cutter 77 can automatically move upward and cut the sheet waste by cooperating with the abutment strip 713. The cut sheet waste is laid flat in the collection box 72. After being pulled and cut, the sheet waste can be stacked in the collection box 72, making the sheet waste in the collection box 72 more neat and improving the utilization rate of the storage space.By using two grinding blocks 79, the two grinding blocks 79 simultaneously move horizontally back and forth while the cutter 77 moves up and down, grinding both sides of the cutter 77 to maintain its sharpness and ensure the cutting effect.

[0048] When the carriage 62 moves left and right, it drives the rotating shaft 81 to move synchronously. The rotating shaft 81 drives the elastic plate 83 to move synchronously through the connecting seat 82. When the lower clamping block 67 moves up and down, it drives the pressure rod 85 to move up and down synchronously through the connecting frame 84. When the pressure rod 85 moves down, it abuts against the connecting seat 82 and drives the connecting seat 82 and the rotating shaft 81 to rotate clockwise. The connecting seat 82 drives the elastic plate 83 to swing downward. After the pressure rod 85 moves up, the rotating shaft 81 is reset by the elastic force of the two coil springs 86. The connecting seat 82 drives the elastic plate 83 to reset. Therefore, when the lower clamping block 67 moves from left to right, the elastic plate 83 does not swing downward because the lower clamping block 67 has not yet moved down. When the lower clamping block 67 moves down, the waste sheet has been cut and fallen into the collection box 72. When the lower clamping block 67 moves to the left, the pressure rod 85 moves down, and the elastic plate 83 swings downward. The elastic sheet 83 also swings downwards. After swinging downwards, the elastic sheet 83 can contact the sheet waste in the collection box 72. The elastic sheet 83 is elastic. When the elastic sheet 83 contacts the top surface of the sheet waste, it deforms and applies a small amount of pressure to the sheet waste. During the leftward movement of the elastic sheet 83, the elastic sheet 83 plays a smoothing role on the sheet waste. When the lower clamping block 67 and the upper clamping block 63 pull the sheet waste to the right, the elastic sheet 83 returns to its original position and does not contact the sheet waste. Through the setting of the smoothing component 8, the elastic sheet 83 can smooth the sheet waste when it moves after entering the collection box 72, making the sheet waste stacked and collected more evenly. This avoids the stacking height from increasing due to wrinkles and curling edges of some sheet waste, which would affect the amount of sheet waste collected in the collection box 72.
