Description

Technical Field

[0001] The invention relates to the technical field of tableware production, and in particular to equipment for producing natural rice husk environment-friendly and degradable tableware. Background Art

[0002] Rice husk is a natural renewable resource. Using rice husk to make tableware can reduce dependence on traditional plastics and reduce environmental pollution. Rice husk tableware can decompose quickly in the natural environment and will not cause long-term harm to the soil and ecosystem. At present, the production of rice husk tableware uses a hot pressing machine with a feeding mechanism to make rice husk sheets into tableware through a hot pressing process. That is, a hot press is used to heat the sheet material made of processed and processed rice husk to a certain temperature to make it soft and plastic, and then the built-in mold mechanism is used to press the heated rice husk sheet into the required shape and size through pressure.

[0003] However, when the rice husk sheet is hot-pressed, only the middle part of the rice husk sheet is used, and the remaining sheet waste is difficult to be directly output from the hot press for crushing treatment on site, so it needs to be rolled up for recycling. The rolled sheet waste has holes formed after the material is taken out, and its actual occupied volume is the same as that of the original unused sheet. Recycling and transfer not only wastes a large amount of transportation space, but also the secondary treatment is relatively troublesome, which is easy to increase the subsequent labor cost. When the general waste treatment mechanism is used to cooperate on site to handle the sheet waste output after hot pressing, it is necessary to manually control the sheet waste. It is troublesome to put the waste materials into the waste treatment mechanism after cutting, and the internal cutting and crushing structure of the general waste treatment mechanism is relatively simple, and it is often only able to roughly cut and crush the waste sheets, which need to be recycled for secondary treatment later. In addition, since the waste sheets have residual temperature, when the waste sheets are crushed, the friction contact of the cutter and the operation of the waste treatment mechanism itself generate heat, and the cutting and crushing structure is relatively sealed to accumulate heat inside. The waste sheets can easily heat up and stick to the cutter and the inside of the waste treatment mechanism, affecting the cutting and crushing effect, and even blocking the internal transportation channel. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that during the general production of rice husk tableware, the sheet waste cannot be directly connected to the hot press for recycling and treatment on site, and the general waste collection mechanism combined with the cutting and crushing effect is poor and the heat dissipation effect is poor.

DETAILED DESCRIPTION

[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Embodiment 1

[0035] like Figure 1-Figure 9 As shown, a natural rice husk environmentally friendly degradable tableware production equipment includes a machine base 1, a hot pressing mechanism is arranged in the middle of the upper end of the machine base 1, a feeding assembly is arranged on the side wall of the hot pressing mechanism, a crushing cylinder 2 is fixedly installed on the front side of the upper end of the machine base 1, the left side of the crushing cylinder 2 is open and the right wall has an air inlet hole 1 in a circular array, a driving screw 22 and a bevel gear shaft 23 are rotatably connected in the middle of the inner cavity of the crushing cylinder 2, the driving screw 22 is driven by a motor 1 installed on the right wall of the crushing cylinder 2, and a driving screw 22 is slidably connected to the inner cavity of the crushing cylinder 2 on the left side. The movable screw 22 is meshed with the pore toothed ring 3, a baffle 31 is fixedly connected to the lower side of the right wall of the pore toothed ring 3, a rotating toothed ring 33 is rotatably connected to the right wall of the pore toothed ring 3, the pore toothed ring 3 has a pore channel covered by the rotating toothed ring 33, a rotary cutter 35 is arranged on the right circumference of the rotating toothed ring 33, and micro pores 36 corresponding to the rotary cutter 35 are arranged on the right wall circumference of the rotating toothed ring 33, and the baffle 31 can block the micro pores 36, and a material trough 24 is arranged on the rear wall of the crushing cylinder 2, and a cutter 5 is arranged in the material trough 24;

[0036] A heat-conducting core tube 6 penetrating a bevel gear shaft 23 is fixedly connected to the middle of the inner cavity of the pulverizing barrel 2, an outer heat-dissipating tube 61 is fixedly connected to the left end of the heat-conducting core tube 6, a liquid pump 62 is fixedly connected between the outer heat-dissipating tube 61 and the right end of the heat-conducting core tube 6, a heat-dissipating fan 63 is fixedly sleeved on the left end of the bevel gear shaft 23, and the outer heat-dissipating tube 61 is composed of a vortex portion arranged on the left side of the heat-dissipating fan 63 and a surrounding portion arranged on the outer wall of the pulverizing barrel 2;

[0037] A waste outlet is arranged on the right side of the bottom of the crushing cylinder 2, a waste outlet bucket 25 is fixedly connected to the bottom of the waste outlet, an elastic filter ring 7 rotatably connected to the inner wall of the crushing cylinder 2 is arranged on the top of the waste outlet, and a filter hole corresponding to the waste outlet is opened at the bottom of the elastic filter ring 7.

[0038] Furthermore, the feeding assembly includes a sheet roller 11 rotatably mounted on the rear wall of the hot pressing mechanism and a pulling roller 12 on the front wall, a transmission belt 15 is movably sleeved between the pulling roller 12 and the right side of the sheet roller 11, a roller frame 16 is slidably connected to the front wall of the hot pressing mechanism, a pressure roller 17 is rotatably connected to the bottom of the roller frame 16, a telescopic cylinder 18 is fixedly connected between the roller frame 16 and the upper wall of the hot pressing mechanism, the pressure roller 17 is located on the upper side of the pulling roller 12, operation ports are opened on the left and right walls of the hot pressing mechanism, and a controller 9 is arranged on the left wall of the hot pressing mechanism, and the controller 9 can control the extension and retraction of the telescopic cylinder 18 and the operation of the hot pressing mechanism.

[0039] Before the production of tableware, ensure that the sheet traction part on the installed sheet roller 11 passes through the inside of the hot pressing mechanism, passes between the pulling roller 12 and the pressing roller 17, and the edge overlaps in the material trough 24. When replacing new sheet raw materials later, use the controller 9 to control the telescopic cylinder 18 to contract so that the roller frame 16 drives the pressing roller 17 to move up. Use the operating ports on the left and right walls of the hot pressing mechanism to operate the sheet traction part in the same way, and use the controller 9 to control the telescopic cylinder 18 to drive the pressing roller 17 to reset and press the sheet, thereby completing the preparation of the sheet. After the sheet is arranged, use the controller 9 to control the operation of the hot pressing mechanism to press it The sheets passing through the hot pressing mechanism are hot pressed to form tableware. After the hot pressing mechanism is finished, the controller 9 automatically controls the cutter 5 to move up and open the material trough 24. The controller 9 controls the feeding assembly to convey the new sheets on the sheet roller 11 forward, and the used sheet waste in the hot pressing mechanism is conveyed forward through the material trough 24 to enter the crushing cylinder 2. The sheet waste is softened after heating and falls to the bottom of the inner cavity of the crushing cylinder 2. When the new sheet is completely conveyed forward to the inside of the hot pressing mechanism, the controller 9 controls the feeding assembly to stop running, and the cutter 5 automatically resets to cut off the sheet waste, and the material trough 24 is closed at the same time.

[0040] During this period, the bevel gear shaft 23 continues to rotate. When the hot pressing mechanism operates again, the rotating gear ring 33 drives the rotary cutter 35 to rotate in a circle to cut the sheet waste. When the motor runs, it drives the driving screw 22 to make the pore gear ring 3 move back and forth once. The bevel gear shaft 23 drives the cooling fan 63 to rotate, so that an air flow flowing to the left is generated inside the crushing barrel 2. After the rotary cutter 35 cuts and breaks up the sheet waste, the sheet waste fragments are attracted to the vicinity of the micro-pores 36, and are further cut and crushed by the rotary cutter 35 again. When the rotating gear ring 33 rotates, the micro-pores 36 are intermittently blocked by the baffle 31, so that the originally attracted sheet waste falls and is cut and crushed by the rotary cutter 35 again, and the cut sheet waste can be attracted to the micro-pores again when the micro-pores 36 rotate over the baffle 31. 36, a dynamic deep cutting of the sheet waste is formed by continuous circulation, and when it is urgent to crush, the rotating toothed ring 33 drives the rotary knife 35 to continuously change the cutting and crushing direction, and can have a stirring effect on the sheet waste, and the degree of cutting and crushing is deep and the effect is good. In the process of the air hole toothed ring 3 being driven to move right, the air hole toothed ring 3 continuously compresses the cutting and crushing space in the crushing cylinder 2, and the sheet waste can be gathered together, thereby increasing the cutting and crushing effect. When the air hole toothed ring 3 pushes the sheet waste into the elastic filter ring 7, the cutting and crushing space is compressed to a minimum, the cutting and crushing effect is maximized, the sheet waste is completely crushed, no secondary rework is required, and the subsequent labor cost is saved, and the crushed sheet waste is automatically discharged and collected by the waste discharge bucket 25 through the filter hole at the bottom of the elastic filter ring 7 through the waste discharge port;

[0041] During the manufacture of tableware, the cooling fan 63 and the liquid pump 62 continue to operate. Due to the rotation of the cooling fan 63, an airflow flowing to the left is generated inside the crushing cylinder 2. This airflow can not only enhance the crushing and pulverizing effect of the sheet waste, but also exchange heat inside the crushing cylinder 2. At the same time, the operation of the liquid pump 62 drives the coolant in the heat-conducting core tube 6 and the outer heat-dissipating tube 61 to flow counterclockwise. The coolant absorbs the heat inside the crushing cylinder 2 through the heat-conducting core tube 6, and when it flows to the vortex part of the outer heat-dissipating tube 61, it is blown by the cooling fan 63 for heat dissipation. When it flows to the surrounding part of the outer heat-dissipating tube 61, it absorbs the heat of the outer wall and exchanges heat with the outside. The overall heat dissipation effect is good, which can prevent the sheet waste from accumulating heat and sticking together, affecting the crushing and pulverizing effect. In addition, since the crushing and pulverizing of the sheet waste is arranged in the sheet processing and forming stage of the hot pressing mechanism, and the crushing is stopped when the sheet is conveyed, the crushing of the sheet waste is performed intermittently, the crushing workload is small, and the crushing and pulverizing is stable and reliable.

[0042] Embodiment 2

[0043] like Figure 3 and Figure 8 As shown, a side support flush with the top of the material pulling roller 12 is provided at the rear end of the material trough 24, and the side support covers the front side of the material pulling roller 12 without contact.

[0044] Since the material trough 24 is blocked by the cutter 5 and the overlap area of ​​the edge of the sheet traction part provided on its periphery is limited, in order to prevent the feeding assembly from transporting the sheet waste to between the pulling roller 12 and the crushing cylinder 2, a side support is used to ensure that the sheet waste is accurately transported toward the material trough 24 when the feeding assembly is in operation.

[0045] Embodiment 3 provides a transmission mechanism of a rotary cutter 35:

[0046] like Figure 6 As shown, the upper side of the air hole toothed ring 3 is rotatably connected to a tooth column 1 32 meshing with the rotating toothed ring 33, the right wall of the rotating toothed ring 33 is rotatably connected to a tooth column 2 34 of a circumferential array, the tooth column 2 34 is meshed and connected with the air hole toothed ring 3, and the rotary cutter 35 is fixedly connected to the right end of the tooth column 2 34;

[0047] The inner wall of the air hole gear ring 3 is rotatably connected with a shaft sleeve 4, and the shaft sleeve 4 is slidably clamped on the outer periphery of the bevel gear shaft 23, and a transmission belt 2 41 is movably sleeved between the shaft sleeve 4 and the gear column 1 32.

[0048] When the bevel gear shaft 23 rotates continuously, the bevel gear shaft 23 drives the shaft sleeve 4 to make the transmission belt 2 41 operate, and the tooth column 1 32 thereby drives the rotating gear ring 33 to rotate, and the rotating gear ring 33 drives each tooth column 2 34 to make the rotary cutter 35 revolve. During the revolution, the tooth column 2 34 and the pore gear ring 3 continuously mesh and rotate, thereby driving each rotary cutter 35 to rotate. When the rotary cutter 35 is used to cut and crush sheet waste, the rotary cutter 35 continuously changes the cutting and crushing direction, and can have a stirring effect on the sheet waste, and the degree of cutting and crushing is deep and the effect is good.

[0049] Embodiment 4 provides a vibration mechanism of an elastic filter ring 7:

[0050] like Figure 6 and Fig. 9 As shown, a slide tube 71 is fixedly connected to the middle of the elastic filter ring 7, the left end of the slide tube 71 is rounded, and a slide groove 72 is provided at the bottom of the slide tube 71;

[0051] A guide ring 42 is fixedly connected to the right end of the shaft sleeve 4 . The guide ring 42 is adapted to the sliding tube 71 . A circumferential array of elastic pins 43 are slidably engaged with the inner wall of the guide ring 42 . The elastic pins 43 can be engaged with the sliding groove 72 .

[0052] When the pore toothed ring 3 moves to the right, the shaft sleeve 4 and the guide ring 42 are synchronously driven to move to the right. Since the shaft sleeve 4 is driven by the bevel gear shaft 23 to rotate continuously, the guide ring 42 rotates continuously. When the compression of the crushing space tends to be minimized, the guide ring 42 can be sleeved on the slide tube 71. When sleeved, the rounded corner design of the left end of the slide tube 71 is used to facilitate the elastic pin 43 to abut against the outer wall of the slide tube 71. When the guide ring 42 drives each elastic pin 43 to rotate and intermittently passes through the slide groove 72, the slide tube 71 drives the elastic filter ring 7 to rotate by utilizing the clamping force between the elastic pin 43 and the slide groove 72. When the elastic filter ring 7 deflects to the maximum extent, the elastic pin 43 automatically disengages from the slide groove 72, and the elastic filter ring 7 automatically resets under the action of its own elastic force. Subsequently, under the drive of the elastic pin 43 and the automatic reset of the elastic filter ring 7, the elastic filter ring 7 continues to vibrate relatively, thereby facilitating the rapid screening of the crushed sheet waste inside it.

[0053] Embodiment 5 provides a driving mechanism for a bevel gear shaft 23 and a liquid pump 62:

[0054] like Figure 6-Figure 7 As shown, a protective cover 21 is fixedly connected to the right side of the crushing barrel 2, and a circular array of air inlet holes is provided on the right wall of the protective cover 21. A driving cone rod 8 meshing with a bevel gear shaft 23 is rotatably connected to the rear wall of the inner cavity of the protective cover 21, and the front end of the driving cone rod 8 is connected to the input of the liquid pump 62, and the driving cone rod 8 is driven by a motor 2 installed on the rear wall of the protective cover 21.

[0055] When the equipment is in use, the second motor drives the driving cone rod 8 to rotate continuously, and the driving cone rod 8 engages to drive the bevel gear shaft 23 to rotate, so as to facilitate the continuous operation of the cooling fan 63. The synchronous driving cone rod 8 drives the liquid pump 62 to operate, so that the coolant circulates continuously between the heat-conducting core tube 6 and the external heat dissipation tube 61. The two heat dissipation methods are carried out simultaneously, thereby avoiding the heat accumulation of sheet waste and causing breakage and adhesion. Through the setting of the protective cover 21, this part of the driving mechanism can be relatively sealed and protected, and dust pollution of this part of the driving mechanism is avoided when the cooling fan 63 is running.

[0056] Embodiment 6 provides a driving mechanism for a feeding assembly and a cutter 5:

[0057] like Figure 7-Figure 8 As shown, a threaded sleeve 81 is rotatably sleeved at the rear of the driving cone rod 8, a friction cone mouth is opened on the front side of the threaded sleeve 81, a friction cone plug 82 adapted to the friction cone mouth is slidably engaged at the front of the driving cone rod 8, a driving block 83 slidably engaged with the right wall of the crushing barrel 2 is rotatably sleeved on the front side of the friction cone plug 82, and a telescopic cylinder 84 is fixedly connected between the driving block 83 and the rear wall of the inner cavity of the protective cover 21.

[0058] The right end of the pulling roller 12 extends to the inside of the protective cover 21, and the right end of the pulling roller 12 is fixedly sleeved with a worm gear 14 that meshes with the threaded sleeve 81. An encoder 13 fixedly connected to the rear wall of the crushing barrel 2 is provided on the right side of the pulling roller 12. The controller 9 can control the extension and retraction of the telescopic cylinder 84 according to the feedback information of the encoder 13.

[0059] When the feeding assembly needs to operate to convey the sheet, the controller 9 controls the telescopic cylinder 84 to contract and drive the driving block 83 to move backward, and the driving block 83 drives the friction cone plug 82 to move backward and abut against the friction cone mouth on the front side of the threaded sleeve 81, and drives the cone rod 8 to drive the friction cone plug 82 to rotate the threaded sleeve 81, and the threaded sleeve 81 drives the worm gear 14 to make the pulling roller 12 rotate at a low speed, and the sheet roller 11 thereby cooperates with the transmission belt 15 to carry out low-speed and reliable conveying of the sheet. During this period, when the pulling roller 12 rotates, the encoder 13 can provide the controller 9 with the conveying length of the sheet by the pulling roller 12 in real time according to the rotation distance of the pulling roller 12, thereby timely controlling the extension and reset of the telescopic cylinder 84 to control the quantitative conveying of the sheet.

[0060] Furthermore, the cutter 5 is slidably clamped in the material trough 24, and the left and right ends of the cutter 5 are fixedly connected with slip rings 51, and the slip rings 51 are rotatably connected to the two ends of the crushing barrel 2. A notch corresponding to the external heat dissipation tube 61 is opened on the right slip ring 51, and a hinge rod 85 is movably connected between the right slip ring 51 and the driving block 83.

[0061] When the feeding assembly needs to operate to convey sheets, the controller 9 controls the telescopic cylinder 2 84 to contract and drive the driving block 83 to move backward. At the same time, the driving block 83 pulls the hinge rod 85 to drive the slip ring 51 on the right to rotate upward. The slip ring 51 on the left thereby cooperates to drive the cutter 5 to rotate upward to open the material trough 24 to facilitate the passage of waste sheets. After the corresponding sheet conveying is completed, the controller 9 controls the telescopic cylinder 2 84 to extend and reset to drive the cutter 5 to seal the material trough 24 and cut off the waste sheets.

[0062] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
