Description

Technical Field

[0001] The invention belongs to the technical field of bamboo and wood product processing equipment, and in particular relates to a high-efficiency forming machine for producing disposable chopsticks. Background Art

[0002] The existing production process of disposable chopsticks generally includes: 1. cutting bamboo pieces into bamboo strips; 2. cutting bamboo strips into chopstick prototypes; 3. bleaching the chopstick prototypes; 4. drying and dehydrating the chopstick prototypes to obtain the final chopstick products.

[0003] There are two main methods for implementing the drying and dehydration steps: first, sun drying and then drying; second, drying throughout the process. These two common drying and dehydration methods each have their own advantages and disadvantages. For example, the former method requires a larger drying space and a slow drying speed, while the latter method consumes more energy and is less economical.

[0004] Therefore, it is necessary to improve the existing drying and dehydration process of disposable chopsticks, and a more efficient chopstick drying equipment is needed.

[0005] For example, the Chinese utility model patent with patent announcement number CN213179331U and announcement date 2021.05.11 discloses a mechanical device for drying and crushing disposable chopsticks. Its drying structure includes: a transport drain box, a first motor, a transport roller, a transport belt, a water collection tank, a first heating wire, a first guide pipe, a drying box, and a first guide plate.

[0006] The disposable chopstick drying structure in this utility model patent allows water to enter the water collection tank better through evenly arranged drainage holes, and is heated and preliminarily dried by the first heating wire at the same time, and then enters the drying box through the first material guide pipe. After three heating and drying processes, the chopsticks are drier and the drying efficiency is higher.

[0007] However, the disposable chopstick drying structure still has at least the following obvious shortcomings during actual production and use, which are also the technical problems to be solved by the present invention, namely:

[0008] In the combination of draining first and then drying, the water removal efficiency of the draining operation is too slow. When the chopsticks enter the drying box, there is still a lot of water on the chopsticks. Therefore, the drying operation time must be extended, which will reduce the efficiency of the drying operation of disposable chopsticks and increase the energy consumption of the drying operation.

[0009] So in summary, there is an urgent need for a new type of combined drying equipment with a relatively faster drying speed and relatively lower drying operation energy consumption for use in the production and molding process of disposable chopsticks. Summary of the invention

[0010] The invention provides a high-efficiency forming machine for producing disposable chopsticks. The machine can arrange a lifting plate unit, a driving motor, a perforated soft bottom plate unit, a hot air pipe unit, and a protruding column unit on a shell unit, so that: 1. the drying operation of wet chopsticks, which is first rotation drying and then hot air drying, has a relatively shorter processing cycle and relatively lower energy consumption; 2. the perforated soft bottom plate unit has three working states of "medium, high, and low", which correspond to the feeding and drying operation, the hot air drying operation, and the sliding and discharging operation of the chopsticks in sequence, so as to ensure that the entire drying and forming operation of the chopsticks is very orderly, stable, and efficient.

[0012] A further preferred technical solution is that the shell unit includes a shell in the shape of a cylinder or a rectangle, an upper feed port and a lower discharge port arranged on the side panel of the shell, a drainage hole arranged on the bottom plate of the shell, and a pipe body hole arranged on the top plate of the shell and used to install the hot air pipe unit.

[0013] A further preferred technical solution is that the lifting plate unit includes a lifting cylinder arranged on the inner bottom surface of the shell, and a material guide plate arranged on the lifting cylinder and with an upper surface inclined downward toward the lower discharge port.

[0014] A further preferred technical solution is that the lifting plate unit also includes a limiting hole arranged on the guide plate, a limiting column arranged on the inner bottom surface of the shell and plugged into the limiting hole, and a triangular block arranged on the upper surface of the guide plate and used to provide a horizontal mounting surface for the drive motor.

[0015] A further preferred technical solution is that the perforated soft chassis unit includes a vertical tube arranged at the center of the circle on the driving motor, a radial plate arranged on the outer ring surface of the vertical tube at the center of the circle, an annular side plate arranged on the radial plate, a fan-shaped soft bottom plate with two radial edges respectively arranged on the two radial plates and used to support chopsticks, and hot air holes arranged on the vertical tube at the center of the circle and the annular side plate.

[0016] A further preferred technical solution is that the perforated soft bottom plate unit also includes a chopstick outlet at the center of the circle arranged on the fan-shaped soft bottom plate, and an outer plate arranged on the lower surface of the fan-shaped soft bottom plate, which receives the lifting action of the protruding column unit and then bends the fan-shaped soft bottom plate upward, and is used to drop the dried chopsticks at the chopstick outlet at the center of the circle.

[0017] A further preferred technical solution is that the perforated soft chassis unit also includes a mounting shaft arranged on the lower end surface of the vertical tube at the center of the circle and connected to the shaft of the driving motor, and a perforated conical panel sleeved on the mounting shaft and used to guide the chopsticks to fall and protect the driving motor.

[0018] A further preferred technical solution is that the hot air pipe unit includes a hot air pipe body arranged on the pipe body hole and used to connect with the vertical pipe at the center of the circle that has risen, and a circular ring plate arranged on the outer ring surface of the hot air pipe body and used to cover the annular side plate.

DETAILED DESCRIPTION

[0036] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0037] As attached Figure 1-11 As shown, a high-efficiency forming machine for producing disposable chopsticks comprises a shell unit 1 for feeding and discharging chopsticks a and for draining water, a lifting plate unit 2 arranged on the inner bottom surface of the shell unit 1 and for obliquely guiding the discharging, a driving motor 3 arranged on the upper surface of the lifting plate unit 2, a perforated soft bottom plate unit 4 arranged on the driving motor 3 and used for rotating and dehydrating the chopsticks a, a hot air pipe unit 5 arranged on the shell unit 1 and used for drying the chopsticks a after dehydration by covering the perforated soft bottom plate unit 4 that has been raised, and a protruding column unit 6 arranged on the inner side surface of the shell unit 1 and located above the lifting plate unit 2 and used for drying the chopsticks a after discharging by lifting the perforated soft bottom plate unit 4.

[0038] In this embodiment, the perforated soft chassis unit 4 has the following three working states in sequence.

[0039] First, the “neutral” state, at which the perforated soft chassis unit 4 is performing the feeding and drying operation of the chopsticks a, and its position is such that it neither touches the hot air pipe unit 5 nor the protruding column unit 6.

[0040] Second, the "high position" state, at this time, the perforated soft chassis unit 4 is performing a hot air drying operation on the chopsticks a, and its position is to touch and dock with the hot air pipe unit 5.

[0041] Third, the “low position” state, at this time, the perforated soft chassis unit 4 is performing the sliding discharge operation of the chopsticks a, and its position is to support the protruding column unit 6.

[0042] The specific height positions of the "middle position" and "low position" states need to be selected and determined by the lifting plate unit 2, while the height position of the "high position" state is unique.

[0043] In addition, the driving motor 3 starts rotating only when the perforated soft chassis unit 4 is in the "middle position", the hot air pipe unit 5 starts ventilation only when the perforated soft chassis unit 4 is in the "high position", and the protruding column unit 6 is fixed and always in position below the perforated soft chassis unit 4.

[0044] Finally, the efficient forming machine is a spin-drying combined machine used in the drying and dehydrating step of chopsticks a. The prior spin-drying operation ensures that chopsticks a are dehydrated in large quantities, while the subsequent drying operation ensures that chopsticks a are fully dehydrated. The former ensures "quantity" and the latter ensures "quality", ultimately making the drying and dehydrating operation of chopsticks a save both time and energy.

[0045] The shell unit 1 includes a shell 101 in the shape of a cylinder or a cuboid, an upper feed port 102 and a lower discharge port 103 arranged on the side panels of the shell 101, a drainage hole 104 arranged on the bottom plate of the shell 101, and a pipe body hole 105 arranged on the top plate of the shell 101 and used to install the hot air pipe unit 5.

[0046] In this embodiment, the drainage hole 104 is located in the middle of the bottom plate to stagger the installation position of the lifting plate unit 2 .

[0047] The lifting plate unit 2 includes a lifting cylinder 201 disposed on the inner bottom surface of the housing 101 , and a material guide plate 202 disposed on the lifting cylinder 201 and having an upper surface inclined downward toward the lower discharge port 103 .

[0048] In this embodiment, the vertical cross-section of the guide plate 202 is a right triangle, and its “acute angle” is facing the lower discharge port 103 .

[0049] The lifting plate unit 2 also includes a limiting hole 203 arranged on the guide plate 202, a limiting column 204 arranged on the inner bottom surface of the shell 101 and plugged into the limiting hole 203, and a triangular block 205 arranged on the upper surface of the guide plate 202 and used to provide a horizontal mounting surface for the drive motor 3.

[0050] In this embodiment, the driving motor 3 is a commonly used stepping motor, which ensures that the rotation angle of the perforated soft chassis unit 4 is flexible and controllable.

[0051] In addition, the inclined surface of the triangular block 205 is close to the inclined surface of the guide plate 202 , so that the plane corresponding to one of the right-angled sides of the triangular block 205 can provide a horizontal installation surface for the drive motor 3 .

[0052] The perforated soft bottom plate unit 4 includes a vertical tube 401 arranged at the center of the circle on the driving motor 3, a radial plate 402 arranged on the outer ring surface of the vertical tube 401 at the center of the circle, an annular side plate 403 arranged on the radial plate 402, a fan-shaped soft bottom plate 404 with two radial edges respectively arranged on the two radial plates 402 and used to support chopsticks a, and hot air holes 405 arranged on the vertical tube 401 at the center of the circle and the annular side plate 403.

[0053] In this embodiment, the fan-shaped soft bottom plate 404 is made of ordinary elastic rubber, and only two radial sides are bonded and fixed, that is, the arcuate side is not bonded to the annular side plate 403, and the part of the radial side close to the center of the circle cannot be bonded either, in order to leave a "gap" for the chopstick a to slide out.

[0054] In addition, the above-mentioned sliding and discharging operation is implemented as follows: the lifting plate unit 2 first controls the soft bottom plate unit 4 with holes to descend, and then the radial outer area of ​​the fan-shaped soft bottom plate 404, that is, the unbonded area is lifted up by the fixed protruding column unit 6, and the fan-shaped soft bottom plate 404 is deformed and tilted, and finally the chopsticks a slide down smoothly at the above-mentioned "notch" to be discharged.

[0055] Therefore, there are certain requirements for the elastic strength of the fan-shaped soft bottom plate 404, which needs to ensure: 1. When the perforated soft bottom plate unit 4 rotates and spins, it can stably support dozens of chopsticks a; 2. When it is pushed upward by the protruding column unit 6, one side of its arc-shaped edge, that is, the radial outer side, can be appropriately and fully bent and tilted upward.

[0056] Finally, during the hot air drying operation of chopsticks a, the specific direction of the hot air is: the hot air pipe unit 5, the vertical pipe 401 at the center of the circle, the space above the fan-shaped soft bottom plate 404, the annular side plate 403, and finally the various openings on the shell 101.

[0057] The perforated soft bottom plate unit 4 also includes a chopstick outlet 406 arranged at the center of the circle on the fan-shaped soft bottom plate 404, and an outer plate 407 arranged on the lower surface of the fan-shaped soft bottom plate 404, which receives the lifting action of the protruding column unit 6 and then bends the fan-shaped soft bottom plate 404 upward, and is used to drop the dried chopsticks a at the chopstick outlet 406 at the center of the circle.

[0058] In this embodiment, the shape of the chopstick opening 406 at the center of the circle is a smaller fan-shaped shape, that is, the specific shape of the fan-shaped soft bottom plate 404 is a fan-shaped ring, and the two sides of the fan-shaped ring can be fully bonded.

[0059] In addition, the specific shape of the outer plate 407 is not fixed, it can be arc-shaped, rectangular, broken line-shaped, etc., and it is only necessary to switch the "point-like" lifting action of the protruding column unit 6 to the "surface-like" lifting force on the fan-shaped soft bottom plate 404.

[0060] In other words, the function of the outer plate 407 is to ensure that one side of the arc-shaped edge of the fan-shaped soft bottom plate 404, that is, the radial outer area, can be bent and deformed upward as much as possible, so that all the chopsticks a that have completed the spin drying and drying operations can finally slide out.

[0061] The perforated soft chassis unit 4 also includes a mounting shaft 408 arranged on the lower end surface of the vertical tube 401 at the center of the circle and connected to the shaft of the driving motor 3, and a perforated conical panel 409 sleeved on the mounting shaft 408 and used to guide the chopsticks a to fall and protect the driving motor 3.

[0062] In this embodiment, the installation shaft 408 is fixedly connected to the vertical pipe 401 at the center of the circle, and the former blocks the end of the latter, ensuring that the latter discharges hot air only at the hot air hole 405.

[0063] In addition, the mounting shaft 408 is connected to the shaft of the driving motor 3 via a coupling, and the functions of the perforated cone panel 409 at least include:

[0064] 1. Prevent chopsticks a from remaining on the driving motor 3;

[0065] 2. Protect the drive motor 3 and the coupling to prevent them from being damaged by chopsticks a.

[0066] The hot air pipe unit 5 includes a hot air pipe body 501 arranged on the pipe body hole 105 and used to connect with the vertical pipe 401 at the center of the circle that has risen, and a circular ring plate 502 arranged on the outer ring surface of the hot air pipe body 501 and used to cover the annular side plate 403.

[0067] In this embodiment, the hot air pipe body 501 is fixedly connected to the vertical pipe 401 at the center of the circle, and the outer end is connected to a hot air blower. The outer diameter of the circular ring plate 502 is greater than or equal to the outer diameter of the annular side plate 403, ensuring that the hot air is discharged only at the hot air hole 405 on the annular side plate 403 as much as possible, thereby improving the heat utilization rate.

[0068] The protruding column unit 6 includes a lateral protruding plate 601 disposed on the inner side of the housing 101, and a vertical column 602 disposed on the lateral protruding plate 601 and used to lift up the outer plate 407 that has been lowered.

[0069] In this embodiment, one outer plate 407 corresponds to at least one vertical column 602, ensuring that all of the fan-shaped soft bottom plates 404 can be "bent at the outer edges and discharged from the inner holes" synchronously.

[0070] In addition, when the perforated soft chassis unit 4 is in the “high position”, the material guide plate 202 will not collide with the lateral protruding plate 601 .

[0071] The housing unit 1 further includes an observation port 106 disposed on the housing 101 and used for monitoring the vertical alignment state of the protruding column unit 6 and the outer side plate 407 .

[0072] In this embodiment, the perforated soft chassis unit 4 needs to ensure a certain circumferential angle range in the following scenarios:

[0073] 1. After the drying operation is completed, it is necessary to ensure that the outer plate 407 is vertically aligned with the protruding column unit 6, that is, the protruding column unit 6 cannot be vertically facing the radial plate 402;

[0074] 2. When the chopsticks a are being fed, the chopsticks a need to be fed as evenly as possible within the multiple intervals divided by the radial plate 402. At this time, the perforated soft chassis unit 4 needs to be rotated while lowering the chopsticks a.

[0075] Therefore, at the observation port 106, the circumferential angle of the perforated soft chassis unit 4 needs to be properly monitored or adjusted, either by manual observation or by existing photoelectric sensing.

[0076] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
