Description

Technical Field

[0001] This utility model belongs to the field of bamboo product manufacturing technology, and in particular relates to a fixed-length device for the production of bamboo chopsticks and other bamboo products. Background Technology

[0002] Bamboo chopsticks are a common and uniquely oriental tableware. In the production of bamboo products, processing bamboo into bamboo materials of a specific length is a basic and crucial process.

[0003] Chinese utility model patent CN217372694U discloses a length-fixing device for producing bamboo chopsticks and other bamboo products. The device involves placing one end of a bamboo piece on a U-shaped base using a first fixing component, then moving a first fixing plate to press and fix that end. A first fixing bolt is then threadedly connected to the first fixing plate to secure it. The other end of the bamboo piece is placed on a fixing block, and a second fixing plate is moved downwards by pressing down a fixing rod, pressing and fixing the other end. The second fixing bolt is then rotated to thread it onto the fixing rod, thus fixing the rod and preventing one end of the chopstick from lifting, thus improving cutting accuracy. However, this device clamps the bamboo at both ends, and after cutting to a fixed length, it requires manual unlocking and control of the bamboo to continue being fed. The operation process is complicated, which affects the efficiency of fixed-length cutting. Furthermore, it is not convenient to quickly recover the cut bamboo products after fixed-length cutting. Moreover, the fixed-length accuracy is low because the drive plate is rotated by a motor and the second fixed component is moved by a drive rod.

[0004] Therefore, there is an urgent need to improve the existing length-fixing equipment used in the production of bamboo chopsticks and other bamboo products, and to provide a length-fixing equipment for bamboo chopsticks and other bamboo products that is more accurate in length setting and has higher processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a length-fixing device for the production of bamboo chopsticks and other bamboo products that is reasonably designed, simple in structure, quick and convenient to operate, and has high precision in length setting and processing efficiency, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A length-fixing device for producing bamboo chopsticks and other bamboo products, comprising: The processing table has vertically upward protrusions on both the top of its left and right sides. A crossbar is symmetrically fixed between the two protrusions. A lead screw is rotatably installed between the middle of the two protrusions. A servo motor is fixed to the top left side wall of the processing table. The left end of the lead screw is fixedly connected to the output end of the servo motor. The slide plate is horizontally slidable on the top of the processing table and between the two protrusions. The middle part of the slide plate is threaded onto the outside of the lead screw. The two ends of the slide plate are respectively slidably sleeved on the outside of the two crossbars. A pointer is fixedly provided on the outer wall of the front of the slide plate. The punching mechanism includes a second bracket fixedly mounted above the slide plate, a second electric telescopic rod fixedly installed in the middle of the second bracket, and a mounting frame slidably located inside the second bracket. The telescopic end of the second electric telescopic rod is fixedly connected to the middle of the top surface of the mounting frame, and a punching blade is fixedly connected to the inner side of the bottom end of the mounting frame by bolts. The bamboo material guiding mechanism includes fixed frames fixedly installed above the left and right sides of the slide. Each set of fixed frames is symmetrically arranged about the front and back of the slide, and a guide roller and an anti-jump roller are installed between the bearings of two fixed frames in the same set.

[0007] Preferably, the system also includes auxiliary components, which include a first bracket, a first electric telescopic rod, a pressure rod, a push rod, and a positioning plate. The first bracket is fixedly mounted on the upper left of the processing table. The first electric telescopic rod is fixedly mounted on the top of the first bracket. The telescopic end of the first electric telescopic rod is fixedly connected to the pressure rod. The positioning plate has an inverted U-shaped longitudinal section, and its front and rear ends are slidably sleeved on the outside of the two crossbars, respectively. There are two push rods, which are symmetrical about the pressure rod. The two ends of the push rods are hinged to the pressure rod and the positioning plate, respectively.

[0008] Preferably, the upper surface of the front end of the processing table is printed with scale markings, the zero mark of the scale markings is on the same vertical plane as the right side wall of the positioning plate, and the value of the scale markings increases from left to right.

[0009] Preferably, the processing table has a guide groove inside, the inner bottom surface of the guide groove is inclined and its opening is opened on the front outer wall of the processing table, and a collection frame is fixedly installed on the front outer wall of the processing table, the collection frame being connected to the interior of the guide groove.

[0010] Preferably, the guide roller and the anti-jump roller are located on the same vertical line, and both the guide roller and the anti-jump roller have multiple positioning grooves at equal intervals along their own length direction on their outer walls.

[0011] Preferably, the positioning groove is a "V" shaped concave surface used to place bamboo.

[0012] Preferably, a controller is also provided, which is a PLC control terminal, and the controller is electrically connected to the servo motor, the first electric telescopic rod and the second electric telescopic rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the zero mark of the scale line is on the same vertical plane as the right side wall of the positioning plate. The tip of the pointer points to the scale line and is on the same vertical plane as the cutting blade. By starting the servo motor to control the lead screw to rotate, the slide plate, the cutting mechanism, and the bamboo material guiding mechanism can be controlled to slide and adjust horizontally and stably along the crossbar. The position of the scale line pointed to by the pointer can be used to accurately determine the distance between the positioning plate and the cutting blade, so that one end of the bamboo material abuts against the right side wall of the positioning plate. Then, the second electric telescopic rod is used to control the cutting blade to press down quickly, which facilitates the fixed-length cutting of the bamboo material. The setting of the two guide rollers on the left and right not only facilitates the stable and smooth feeding of the bamboo material, but also facilitates the support on both sides of the bamboo material cutting point to ensure stable cutting. At the same time, the anti-jump roller can prevent the bamboo material from jumping up during the cutting process.

[0014] After the bamboo is cut, this invention controls the pressure rod to move vertically downwards stably by activating the first electric telescopic rod. During this process, the push rods hinged on the front and rear sides of the pressure rod can push the positioning plate to move steadily to the left along the crossbar, so that the positioning plate disengages from the end of the bamboo. Then, the downward-moving pressure rod can press down on one end of the bamboo, causing the cut bamboo to fall into the guide trough. The inclined inner bottom surface of the guide trough facilitates the collection of the bamboo in the collection frame, achieving the design purpose of easy material retrieval. Compared with the prior art, this device can achieve continuous feeding and punching of bamboo, with a simple operation process and higher efficiency for fixed-length cutting.

The first bracket 51 is fixedly installed on the upper left of the processing table 1. The first electric telescopic rod 52 is fixedly installed at the top of the first bracket 51. The telescopic end of the first electric telescopic rod 52 is fixedly connected to the pressure rod 53. The longitudinal section of the positioning plate 55 is an inverted "U" shape, and its front and rear ends are respectively slidably sleeved on the outside of the two crossbars 4. There are two push rods 54, which are symmetrical about the pressure rod 53. The two ends of the push rod 54 are respectively hinged to the pressure rod 53 and the positioning plate 55.

[0019] In this embodiment, the first electric telescopic rod 52 is activated to control the pressure rod 53 to move vertically downward in a stable manner. The positioning plate 55 can be pushed to the left along the crossbar 4 by the push rod 54, so that the positioning plate 55 can be separated from the end of the bamboo. Then, the downward pressure rod 53 is used to press the cut bamboo into the guide trough 6 for easy bamboo collection.

[0020] As a preferred embodiment, based on the above structure, the upper surface of the front end of the processing table 1 is further printed with a scale mark 17. The zero mark position of the scale mark 17 is on the same vertical plane as the right side wall of the positioning plate 55, and the value of the scale mark 17 increases from left to right.

[0021] In this embodiment, the scale markings 17 are used to make it easier to accurately determine the distance between the positioning plate 55 and the punching blade 13, which facilitates precise length punching of bamboo.

[0022] As a preferred embodiment, based on the above structure, the processing table 1 is further provided with a guide groove 6 inside. The inner bottom surface of the guide groove 6 is inclined and its opening is opened on the front outer wall of the processing table 1. A collection frame 7 is fixedly installed on the front outer wall of the processing table 1, and the collection frame 7 is connected to the inside of the guide groove 6.

[0023] In this embodiment, the inclined inner bottom surface of the guide trough 6 is used to facilitate the collection of bamboo materials into the collection frame 7, thereby achieving the design purpose of easy material retrieval.

[0024] As a preferred embodiment, based on the above structure, the guide roller 15 and the anti-jump roller 16 are located on the same vertical line, and the outer walls of both the guide roller 15 and the anti-jump roller 16 are provided with multiple positioning grooves at equal intervals along their own length direction.

[0025] As a preferred embodiment, based on the above structure, the positioning groove is further defined as a "V"-shaped concave surface for placing bamboo.

[0026] In this embodiment, the positioning groove is used to effectively improve the stability of the bamboo during the bamboo feeding process, prevent the bamboo from tilting, and ensure its length accuracy.

[0027] As a preferred embodiment, based on the above structure, a controller 18 is further provided, which is a PLC control terminal. The controller 18 is electrically connected to the servo motor 2, the first electric telescopic rod 52 and the second electric telescopic rod 11.

[0028] In this embodiment, the controller 18 is used to facilitate the control of the operation of the servo motor 2, the first electric telescopic rod 52, and the second electric telescopic rod 11.

[0029] The working principle of this utility model is as follows: In use, firstly, according to the actual length production requirements of the bamboo chopsticks, start the servo motor 2 to control the screw 3 to rotate, and control the slide plate 8, the punching mechanism and the bamboo material guiding mechanism to slide horizontally along the crossbar 4 in sync. Use the scale mark 17 pointed to by the pointer 9 to accurately judge the distance between the positioning plate 55 and the punching blade 13, thereby determining the cutting length of the bamboo chopsticks. Then, place the bamboo material in the multiple positioning grooves opened on the outer wall of the guide roller 15 and push it until the end of the bamboo material abuts against the positioning plate 55. The opening of the positioning grooves can prevent the bamboo material from tilting during the guiding process. Then, start the second electric telescopic rod 11 to control the mounting frame 12 and the punching blade 13 to quickly move down to cut the bamboo material. The two guide rollers 15 on the left and right not only facilitate the stable and smooth guiding of the bamboo material, but also facilitate the support on both sides of the bamboo material cutting point to ensure stable cutting. At the same time, the anti-jump roller 16 can prevent the bamboo material from jumping up during the cutting process. After cutting, the first electric telescopic rod 52 is activated to control the pressure rod 53 to move vertically downward. The push rods 54, which are hinged on both the front and rear sides of the pressure rod 53, can push the positioning plate 55 to move to the left along the crossbar 4, so that the positioning plate 55 is disengaged from the end of the bamboo. Then, the downward-moving pressure rod 53 can press down on one end of the bamboo, which can press the cut bamboo into the guide groove 6 opened inside the processing table 1. The inclined inner bottom surface of the guide groove 6 is used to facilitate the collection of bamboo into the collection frame 7, achieving the design purpose of easy material retrieval. Then, the pressure rod 53 and the positioning plate 55 are controlled to return to their original positions. Compared with the prior art, the positioning plate 55, pointer 9 and scale marks 17 of this device can achieve precise length setting of bamboo materials, and without repeated clamping operations, it can achieve continuous feeding and continuous punching of bamboo materials. Not only is the operation process simple, but the efficiency of length cutting is also higher, which is conducive to further improving the production capacity of the equipment and making it more practical. It should be noted that linear bearings can also be installed between the positioning plate 55 and the sliding plate 8 and the crossbar 4 to improve the smoothness of sliding and reduce friction. In addition, this device uses an external power supply to enable the equipment to operate. The circuit connection and specific control methods between the servo motor 2, the first electric telescopic rod 52 and the second electric telescopic rod 11 and the controller 18 are all mature existing technologies, so they will not be described in detail.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
