Description

Technical Field

[0001] This invention relates to the field of centrifugal drying technology, specifically to an automated production line for centrifugal drying of plastic crates. Background Technology

[0002] The workload of recycling and cleaning plastic crates used for transporting agricultural and livestock products is very large. Traditionally, plastic crates for agricultural and livestock products are usually cleaned manually or by equipment and then dried by natural air drying (which takes a very long time and takes up a large area) or hot air drying (which takes a long time and consumes a lot of energy). Therefore, it is necessary to develop equipment for rapid drying of cleaned plastic crates.

[0003] For example, the invention patent with publication number CN113758160A and titled "A Plastic Crate Spin Dryer" includes: a spin drying device, which includes a lifting mechanism for moving the plastic crate up and down, a downward pressure turntable installed on the upper part of the lifting mechanism, and a spin drying turntable corresponding to the downward pressure turntable at the lower end of the lifting mechanism; a side pushing device, which is installed on both sides of the upper end of the spin drying device, the lifting mechanism is located between the two side pushing devices, the side pushing device is provided with a push plate for pushing the plastic crate forward, and the lower ends of the side pushing device are provided with first support plates for supporting the plastic crate, the lifting mechanism is located between the first support plates at both ends and corresponds to the first support plates. It uses a lifting mechanism to drive a downward-pressing turntable to press down, causing the plastic basket to be pressed onto the spin-drying turntable. The spin-drying turntable drives the plastic basket to rotate, causing the water on the plastic basket to separate from the plastic basket under the action of centrifugal force, thereby achieving a drying effect. The overall structure occupies relatively little space, does not require a drying method, and is environmentally friendly and energy-saving. The plastic basket is pushed onto the lifting mechanism by a push plate for spin-drying, making it convenient to transport.

[0004] The aforementioned patent requires separate feeding conveyor and discharging conveyor, with a first pallet and a second pallet for transition between them. A side-pushing device is also needed to transfer the plastic baskets on the feeding conveyor to the lifting mechanism. After the plastic baskets are spun dry, they also need to be transferred from the lifting mechanism to the discharging conveyor via the side-pushing device. The structure and operation steps are quite cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide an automated production line for centrifugal drying of plastic crates to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated production line for centrifugal drying of plastic crates, comprising: a frame; a conveying assembly disposed on the frame for conveying plastic crates; a centrifugal assembly comprising a second motor and a contouring fixture, the second motor being disposed on the frame for driving the contouring fixture to rotate; and a supporting assembly comprising a base and a lifting unit movably disposed on the base, the lifting unit being located directly below the contouring fixture; when the conveying assembly conveys the plastic crate between the lifting unit and the contouring fixture, the lifting unit slides upward relative to the base to lift the plastic crate to clamp the plastic crate with the contouring fixture; when the centrifugal drying of the plastic crate ends, the lifting unit slides downward relative to the base to disengage the plastic crate from the contouring fixture and drop it onto the conveying assembly.

[0007] Furthermore, the conveying assembly includes two rollers rotatably mounted on a frame, with two parallel chain mechanisms between the two rollers. A first motor is mounted on the frame and is used to drive either roller to rotate. The chain mechanism includes two sprockets and a chain. Each of the two sprockets is fixedly connected to one roller, and the chain drive is connected between the two sprockets.

[0009] Furthermore, the frame is provided with transition roller assemblies located at both ends of the conveying assembly.

[0010] Furthermore, an annular cover is fixedly connected to the frame, and the annular cover covers the contouring tooling fixture.

[0011] Furthermore, it also includes a positioning assembly mounted on the frame. The positioning assembly includes a rotating rod, at least one stop rod, a cylinder, and two sets of waterproof through-beam photoelectric sensors. The rotating rod is rotatably connected to the frame, the stop rod is fixedly connected to the rotating rod, the cylinder seat of the cylinder is hinged to the frame, the extension rod of the cylinder is rotatably connected to the rotating rod, and the two waterproof through-beam photoelectric sensors are arranged side by side on the frame along the conveying direction of the conveying assembly.

[0012] Furthermore, it also includes a passive synchronous drive mechanism, which receives the conveying power from the conveying component to drive the lifting unit to slide relative to the base, thereby enabling the contour tooling fixture to load and unload the plastic basket.

[0013] Furthermore, the passive synchronous drive mechanism includes: multiple positioning blocks arranged in an array along the length of the chain; multiple stops spaced apart on each positioning block; a movable seat mounted on a frame along the conveying direction of the conveying assembly; a slide rod vertically slidably mounted on the movable seat, with a first elastic element between the slide rod and the movable seat, the elastic force of the first elastic element acting upward on the slide rod to position the slide rod on the movement path of the stops; an abutment member having an inclined surface; a first rack vertically fixedly connected to the sliding part of the lifting unit; and a worm gear. The worm gear structure includes a meshing worm and a worm wheel, both rotatably connected to the frame; two unidirectional transmission structures, one of which is driven by the movement of the moving seat along the conveying direction of the conveying assembly to make the worm rotate forward, and the other is driven by the movement of the moving seat along the conveying direction of the conveying assembly to make the worm rotate in reverse; a trigger element, which is fixedly connected to the frame and movably abuts against the inclined surface of the moving abutment element to make the slide bar move downward relative to the moving seat and disengage from the stop block; and a second elastic element whose elastic force acts on the moving seat in the opposite direction of the conveying direction of the conveying assembly.

[0014] Furthermore, the one-way transmission mechanism includes a transmission gear coaxially rotatably connected to the shaft of the worm, the transmission gear meshing with a second rack fixedly connected to the movable seat, a ratchet coaxially fixedly embedded on the transmission gear, and a pawl elastically hinged to the shaft of the worm to cooperate with the ratchet.

[0015] Furthermore, a damping wheel is rotatably mounted on the frame, which causes the plastic basket on the conveying assembly to abut against the adjacent positioning block upstream.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-8This invention provides an automated production line for centrifugal drying of plastic crates, comprising a frame 1, a conveying assembly 2, and a support assembly 4. The conveying assembly 2 is mounted on the frame 1 and is used to convey plastic crates. The centrifugal assembly 3 includes a second motor 3.1 and a contouring fixture 3.2. The second motor 3.1 is mounted on the frame 1 and is used to drive the contouring fixture 3.2 to rotate. The second motor 3.1 is preferably a cruise positioning motor. The support assembly 4 includes a base 4.1 and a lifting unit movably mounted on the base 4.1. The lifting unit is located directly below the contouring fixture 3.2. When the conveying assembly 2 conveys the plastic crate between the lifting unit and the contouring fixture 3.2, the lifting unit slides upward relative to the base 4.1 to lift the plastic crate and clamp it with the contouring fixture 3.2. When the centrifugal drying of the plastic crate ends, the lifting unit slides downward relative to the base 4.1 to disengage the plastic crate from the contouring fixture 3.2 and drop it onto the conveying assembly 2.

[0029] The specific workflow is as follows: The conveying component 2 transports the plastic basket to be dried between the lifting unit and the contouring fixture 3.2. The lifting unit slides upward relative to the base 4.1 to lift the plastic basket, so that the plastic basket enters the contouring fixture 3.2 with its bottom opening. The plastic basket is clamped together with the contouring fixture 3.2. Then, the second motor 3.1 of the centrifugal component 3 drives the contouring fixture 3.2 to rotate. The contouring fixture 3.2 drives the plastic basket to rotate, thereby centrifugally drying the plastic basket. After the plastic basket is centrifugally dried, the lifting unit of the support component 4 descends and then places the plastic basket onto the conveying component 2. Then, the conveying component 2 transports the dried plastic basket away. This is one drying cycle of a plastic basket.

[0030] The present invention provides an automated production line for centrifugal drying of plastic crates. Only one set of conveying components 2 is needed to complete the feeding and discharging of plastic crates. The support component 4 can directly lift the plastic crates on the conveying component 2 into the conformal tooling fixture 3.2 of the centrifugal component 3. After the plastic crates are centrifuged and dried, the support component 4 can directly lower them onto the conveying component 2, thereby completing the feeding, centrifugal drying and discharging of plastic crates. The present invention has a compact and non-redundant structure and simple operation steps. Unlike the prior art, it does not require separate feeding and discharging conveying frames, nor does it require the first pallet, the second pallet and the side pushing device.

[0031] As a preferred embodiment of the present invention, the conveying assembly 2 includes two rollers 2.1 rotatably mounted on the frame 1, with two parallel chain mechanisms 2.2 between the two rollers 2.1. A first motor 2.3 is mounted on the frame 1, which drives either roller 2.1 to rotate. Each chain mechanism 2.2 includes two sprockets and a chain. Each sprocket is fixedly connected to one roller 2.1, and the chain drive is connected between the two sprockets. Furthermore, a support plate is fixedly mounted on the frame 1 to support the chain and improve the downward curvature of the chain's middle section. Further, two parallel side limiting plates are also provided on the frame 1, located on the outer sides of the two chains, to limit the position of the plastic basket placed on the two chains, ensuring the plastic basket remains upright.

[0032] As a preferred embodiment of the present invention, the lifting unit includes a sliding part 4.2 and a platform 4.3. The sliding part 4.2 is vertically slidably connected to the base 4.1, and the platform 4.3 is rotatably connected to the sliding part 4.2. A hydraulic device 4.4 for driving the sliding part 4.2 to slide relative to the base 4.1 is provided between the base 4.1 and the sliding part 4.2. Further, the hydraulic device 4.4 can be replaced by a mechanism that outputs linear reciprocating motion, such as an electric push rod. When the centrifugal assembly 3 is working, the contouring fixture 3.2, the plastic basket, and the platform 4.3 rotate synchronously together.

[0033] As a preferred technical solution, the frame 1 is provided with transition roller assemblies 5 located at both ends of the conveying assembly 2. The transition roller assemblies 5 can assist in loading the plastic basket onto the conveying assembly 2 and removing it from the conveying assembly 2.

[0034] As a preferred technical solution, an annular cover 6 is fixedly connected to the frame 1. The annular cover 6 covers the contouring fixture 3.2. The annular cover 6 has filter holes on its peripheral side, which can play a protective role without affecting the water discharge.

[0035] As a preferred technical solution, a positioning component 7 is also included, mounted on the frame 1. The positioning component 7 includes a rotating rod 7.1, at least one stop rod 7.2, a cylinder 7.3, and two sets of waterproof through-beam photoelectric sensors 7.4. The rotating rod 7.1 is rotatably connected to the frame 1. Preferably, there are two stop rods 7.2, which are fixedly connected to the rotating rod 7.1. The cylinder seat of the cylinder 7.3 is hinged to the frame 1, and the telescopic rod of the cylinder 7.3 is rotatably connected to the rotating rod 7.1. The two waterproof through-beam photoelectric sensors 7.4 are arranged side-by-side on the frame 1 along the conveying direction of the conveying component 2. The positioning component 7 enables the plastic basket of the conveying component 2 to be accurately positioned between the platform 4.3 and the contouring fixture 3.2, thereby allowing the platform 4.3 to accurately lift the plastic basket into the contouring fixture 3.2.

[0036] In another embodiment of the present invention, a passive synchronous drive mechanism 8 is also included. The passive synchronous drive mechanism 8 receives the conveying power from the conveying component 2 to drive the lifting unit to slide relative to the base 4.1, thereby realizing the loading and unloading of the plastic basket by the contour tooling fixture 3.2.

[0037] Specifically, the passive synchronous drive mechanism 8 includes multiple positioning blocks 8.1, multiple stop blocks 8.2, a movable seat 8.3, a slide bar 8.4, abutment member 8.6, a first rack 8.11, a worm gear 8.10, a worm 8.9 structure, two unidirectional transmission structures 8.7, a gear set 8.8, a trigger member 8.12, and a second elastic member 8.13. The multiple positioning blocks 8.1 are arrayed along the length of the chain and are specifically positioned on the chain plates or chain pins. The multiple stop blocks 8.2 are spaced apart from each positioning block 8.1. Above, a stop block 8.2 is fixedly connected to one of any two adjacent positioning blocks 8.1; the movable seat 8.3 is movable on the frame 1 along the conveying direction of the conveying assembly 2, such as a sliding connection or a rolling connection; the slide rod 8.4 is vertically slidably mounted on the movable seat 8.3, and a first elastic element 8.5 is provided between the slide rod 8.4 and the movable seat 8.3. The elastic force of the first elastic element 8.5 acts upward on the slide rod 8.4 so that the slide rod 8.4 is located on the movement path of the stop block 8.2; the abutment member 8.6 has an inclined surface; the first rack 8.11 is fixedly connected to the lifting... On the sliding part 4.2 of the lowering unit, the length direction of the first rack 8.11 is vertical; the worm gear 8.10 and worm 8.9 structure includes a meshing worm 8.9 and worm gear 8.10, both of which are rotatably connected to the frame 1; one of the two unidirectional transmission structures 8.7 is driven by the moving seat 8.3 moving along the conveying direction of the conveying assembly 2 to make the worm 8.9 rotate forward, and the other is driven by the moving seat 8.3 moving along the conveying direction of the conveying assembly 2 to make the worm 8.9 rotate in reverse. Here, forward and reverse rotation only indicate The opposite rotation direction does not represent the clockwise direction; the input gear 8.81 of the gear set 8.8 is coaxially and fixedly connected to the worm gear 8.10, and the output gear 8.82 of the gear set 8.8 meshes with the first rack 8.11; the trigger 8.12 is fixedly connected to the frame 1, and the trigger 8.12 moves and abuts against the inclined surface of the moving abutment 8.6, so that the slide rod 8.4 moves down relative to the moving seat 8.3 and disengages from the stop block 8.2; the elastic force of the second elastic member 8.13 acts on the moving seat 8.3 in the opposite direction of the conveying direction of the conveying assembly 2.

[0038] As a preferred embodiment, each one-way transmission mechanism includes a transmission gear 8.71, a second rack 8.72, a ratchet 8.73, and a pawl 8.74. The transmission gear 8.71 is coaxially rotatably connected to the shaft of the worm 8.9. The second rack 8.72 is fixedly connected to the movable seat 8.3, and the transmission gear 8.71 and the second rack 8.72 mesh with each other. The ratchet 8.73 is coaxially fixedly embedded in the transmission gear 8.71. The pawl 8.74 is elastically hinged to the shaft of the worm 8.9, and the pawl 8.74 engages with the ratchet 8.73. The two one-way transmission mechanisms are arranged with a height difference, and the ratchet 8.73 and pawl 8.74 of the two one-way transmission mechanisms are arranged in opposite ways.

[0039] In this embodiment, the chain drives the plastic basket to be dried on the positioning block 8.1 to move together. When the stop block 8.2 on the positioning block 8.1 engages with the slide rod, the positioning block 8.1, through the stop block 8.2 and the slide rod, drives the movable seat 8.3 to move synchronously. The movable seat 8.3 drives the abutment block and the two second racks 8.72 to move together. One of the second racks 8.72 of the one-way transmission mechanism meshes with the corresponding transmission gear 8.71, causing the worm 8.9 to rotate clockwise. The worm 8.9 drives the worm wheel 8.10 to rotate. The worm wheel 8.10 drives the first rack 8.11 to move upward through the gear set 8.8. The first rack 8.11 drives the sliding part 4.2 and the platform 4.3 together. The platform 4.3 lifts the plastic basket on the chain upwards. When the positioning block 8.1 moves the plastic basket directly below the contour jig 3.2, meaning the plastic basket is fully aligned with the contour jig 3.2, the platform 4.3 lifts the plastic basket to a height where the bottom of the plastic basket is higher than the top of the positioning block 8.1. The plastic basket then disengages from the positioning block 8.1, allowing the positioning block 8.1 to continue moving with the chain without dragging the plastic basket along. The platform 4.3 then lifts the plastic basket further into the contour jig 3.2, where the platform 4.3 and the contour jig 3.2 clamp the plastic basket. At this point, the second rack 8.72 of the one-way transmission mechanism is aligned with the corresponding transmission... Gear 8.71 disengages, at which point conveying assembly 2 pauses comfortably, centrifugal assembly 3 starts, and the contouring fixture 3.2 drives the plastic basket and platform 4.3 to rotate together. After the plastic basket is centrifuged and spun dry, centrifugal assembly 3 shuts off, the plastic basket stops rotating, and conveying assembly 2 continues to move in its original direction. The positioning block 8.1 continues to drive the moving seat 8.3 to move synchronously. When the second rack 8.72 of another one-way transmission mechanism begins to mesh with the corresponding transmission gear 8.71, the worm 8.9 reverses. The worm 8.9 drives the first rack 8.11 to move downward through the worm wheel 8.10 and gear set 8.8. The first rack 8.11 drives the sliding part 4.2 and platform 4.3. Together, they move downwards, allowing the platform 4.3 to reposition the plastic crate onto the chain. The chain then transports the spun-dry plastic crate between the platform 4.3 and the contour jig 3.2. Simultaneously, the abutment 8.6 on the positioning block 8.1 engages with the trigger 8.12. First, the inclined surface of the abutment 8.6 slides and engages with the trigger 8.12, causing the abutment 8.6 and the slide rod 8.4 to move downwards relative to the moving seat 8.3. This disengages the slide rod 8.4 from the stop block 8.2 on the positioning block 8.1. At this point, the elastic force of the second elastic element 8.13 immediately pulls the moving seat 8.3 in the opposite direction of the conveying direction of the conveying assembly 2, returning the moving seat 8.3 to its initial position. This completes one drying cycle for a plastic crate.

[0040] As a preferred technical solution in this embodiment, a damping wheel 9 is rotatably provided on the frame 1. When the conveying component 2 conveys the plastic basket past the damping wheel 9, the damping wheel 9 rolls and engages with the upper side of the plastic basket. Since the damping wheel 9 itself has rolling resistance, the plastic basket on the conveying component 2 can abut against the upstream adjacent positioning block 8.1. Thus, when the plastic basket to be dried is placed on the chain of the conveying component 2, it is not necessary to deliberately make the plastic basket abut against the upstream adjacent positioning block 8.1. Before the plastic basket reaches the platform 4.3, it will be corrected by the damping wheel 9 and abut against the upstream adjacent positioning block 8.1, making loading more convenient and also improving the accuracy of the conforming tooling fixture 3.2 fitting the plastic basket.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
