Abstract
Description
[0001] The present application claims priority to Chinese prior application No. 2024212534600, filed on June 3, 2024; and Chinese prior application No. 2024112066234, filed on August 30, 2024; the contents of which are hereby incorporated by reference in their entirety as part of the present utility model. TECHNICAL FIELD
[0002] The utility model belongs to the mechanical field, concretely relates to a kind of automatic displacement mechanism of mould pressing tray. BACKGROUND
[0003] As the most basic container equipment of container unit and unit logistics, tray is closely related to the development of logistics industry. In recent years, the logistics industry has grown steadily, and with the implementation of tray transportation in the country, the tray industry has also developed vigorously. As the main body of goods movement and handling, tray is mainly used to protect goods, realize the automation of goods transportation and improve the efficiency of goods circulation. In today's bulk commodity trade system, weight is often used as the unit of measurement of transaction value, such as goods weight, prevention of transportation vehicle overweight, real-time weight increase or decrease measurement during goods use, etc. This makes it possible to realize the visualization of goods weight, which greatly improves the efficiency of trade.
[0004] Mould pressing tray is a full name of plant fiber mould pressing plane industrial tray. The raw materials of common mould pressing tray are shavings, plant straw, bamboo and wood, which is a whole structure, and the panel and supporting foot are molded and formed at one time. The upper surface of the tray plate is smooth and flat, which can meet the transportation of various goods. The lower surface is provided with reinforcing ribs. The vertical and horizontal stress of the plate surface is balanced, and the nine feet can meet the four-way insertion of forklift, which belongs to plane four-way forking single tray.
[0005] Because the raw materials of mould pressing tray come from recyclable resources such as straw, branches, wood chips, bamboo chips and bamboo fertilizer, the production process usually adopts hot pressing and other methods. The raw materials and process are more environmentally friendly. Therefore, mould pressing tray is increasingly occupying the theme of tray market, and the research on mould pressing tray is also more and more intensive. How to better use environmentally friendly raw materials and how to improve the carrying capacity and strength of tray are the key research directions of mould pressing tray.
[0006] Compared with traditional plastic pallets or wooden pallets, the molded pallet has the advantages of environment-friendly material, simplified manufacturing process, low manufacturing cost, small environmental pollution in manufacturing process and less post-manufacturing processing procedures. As for the pallet itself, the molded pallet has high compressive strength and good wear resistance due to the compaction treatment of waste materials in the form of powder, and the use scenarios are more extensive. Compared with traditional wooden pallets, the molded pallet undoubtedly has great advantages in material selection. The molded pallet is usually made of wood chips and other processing waste or crop waste such as straw. Compared with wooden pallets that need to cut trees for material, the molded pallet not only reduces the cost, but also meets the requirements of energy saving, environmental protection and protection of non-renewable resources.
[0007] After being pressed and formed, the molded pallet has many burrs on the outer edge surface, and needs to be edge-milled to obtain the final molded pallet product. At present, the edge-milling of the molded pallet is still completed manually. The molded pallet is large in size, and manual processing is very time-consuming and labor-intensive, low in efficiency, high in cost, harmful to the health of the operator due to dust pollution, and the edge-milling effect has personal differences, which is not conducive to the quality control of the molded pallet. Therefore, it is urgent to find a method for automatically edge-milling the molded pallet to realize automatic control of the whole edge-milling process. Practical new type content
[0008] To solve the above problems, the utility model provides a kind of automatic displacement mechanism of molded pallet edge-milling machine, including clamping assembly, moving track and positioning mechanism, clamping assembly is used to grab workpiece, moving track is used to carry clamping assembly displacement, positioning mechanism controls workpiece placement position and height, automatic displacement mechanism can collect workpiece to be polished and place in automatic edge-milling mechanism, or workpiece that finishes polishing is removed from automatic edge-milling mechanism, reach the purpose of the automatic displacement of workpiece, to cooperate with automatic edge-milling mechanism, realize the automatic edge-milling of molded pallet whole process together.
[0009] In one aspect, the utility model provides a kind of automatic displacement mechanism of molded pallet edge-milling machine, including clamping assembly and moving track, clamping assembly is connected with moving track, the clamping assembly is used to grab workpiece;The moving track is used to carry clamping assembly displacement.
[0010] In some ways, the molded pallet edge-milling machine includes an automatic edge-milling mechanism and an automatic displacement mechanism;The automatic edge-milling mechanism is used for automatically polishing workpiece to be polished;The automatic displacement mechanism is used to place workpiece to be polished in the automatic edge-milling mechanism, or remove workpiece that finishes polishing from the automatic edge-milling mechanism.
[0011] In order to realize the whole process automation grinding, not only need to provide accurate and stable automatic polishing function for the workpiece, the automatic displacement of the workpiece is also very important, because the workpiece can be accurately placed in the right place, is the premise of the completion of the polishing work. Once the workpiece placement position offset, will directly affect the final polishing effect. At the same time after grinding, the workpiece can be moved in time, and the new workpiece is moved in time and accurately, also directly related to the smooth operation of the automatic grinding line, if the workpiece can not be moved in time, or the new workpiece can not be moved in time, or the workpiece is stuck, skew, impact and other situations in the moving process, will directly disrupt the rhythm of the assembly line, serious even may cause safety accidents, cause great loss. Therefore, the automatic grinding mechanism and the automatic displacement mechanism must be perfect, in order to realize the whole process automation grinding.
[0012] Further, the clamping assembly comprises a first clamping assembly and a second clamping assembly, which are arranged on the two sides of the automatic grinding mechanism. The first clamping assembly runs back and forth above the automatic grinding mechanism at the first position, and the second clamping assembly runs back and forth above the automatic grinding mechanism at the second position. The first clamping assembly is used to grasp the workpiece to be polished from the first position and place it into the automatic grinding mechanism. The second clamping assembly is used to grasp the workpiece that has completed polishing and place it into the second position.
[0013] In some ways, the first clamping assembly and the second clamping assembly need to run simultaneously and work synchronously, that is, when the first clamping assembly grasps the workpiece to be polished from the first position, the second clamping assembly is also grasping the workpiece that has completed polishing. When the first clamping assembly places the workpiece to be polished into the automatic grinding mechanism, the second clamping assembly is also placing the workpiece that has completed polishing into the second position. Synchronous operation can improve the operating efficiency of the clamping assembly, and synchronous control of the first clamping assembly and the second clamping assembly can not only ensure the control accuracy, but also reduce the control cost.
[0014] In some ways, the automatic grinding mechanism is located at the middle position, and the first clamping assembly and the second clamping assembly are arranged on the two sides of the automatic grinding mechanism, which can be any position of the front, back, left and right of the automatic grinding mechanism, as long as they are not in the same position.
[0015] In some ways, the workpiece is a molded tray, which has large volume and heavy weight. In order to facilitate use and avoid errors, the first clamping assembly and the second clamping assembly are preferably arranged on the left and right sides of the automatic grinding mechanism.
[0016] Further, the clamping assembly comprises a base, a clamping piece and a cylinder piston, and the clamping piece is located on the base. The cylinder piston comprises a first cylinder piston and a second cylinder piston. The first cylinder piston is used to control the rising and falling of the base, and the second cylinder piston is used to control the opening and closing of the clamping piece, so as to realize the grasping and placing of the workpiece.
[0017] In some embodiments, the base matches the shape and size of the mold tray, and each clamping assembly is equipped with two clamping plates, one on each side of the base. When the clamping assembly is moved above the mold tray, the first cylinder piston pushes the base downward to approach the mold tray, and then the second cylinder piston pushes the clamping plates together to grasp the two sides of the mold tray. The second cylinder piston is further divided into a left cylinder and a right cylinder, respectively controlling the opening and closing of the left and right clamping plates. When the second cylinder piston is opened, the two clamping plates close together; when the second cylinder piston is closed, the two clamping plates open to the sides.
[0018] The clamping piece is a one-way long clamping piece that can contact and clamp the edge of the molded tray over a large area, ensuring a more stable clamping process and helping to achieve precise displacement of the molded tray.
[0019] Furthermore, the automatic displacement mechanism also includes a moving track and a horizontal moving power source; the horizontal moving power source is used to control the left and right movement of the clamping assembly in the horizontal direction; the clamping assembly is connected to the moving track through a pulley.
[0020] Furthermore, the horizontal movement power source includes a belt and a pulley, the pulley drives the belt to move, and the upper end of the clamping assembly is fixed on the belt and can move horizontally left and right along with the belt.
[0021] The design of the moving track can help stabilize the moving position of the clamping component and prevent position deviation. It is equivalent to the combination of the belt and the moving track, which together provide a stable double insurance for the repeated horizontal movement of the clamping component and ensure the accuracy of the horizontal movement position.
[0022] Furthermore, the automatic displacement mechanism also includes a positioning system, which includes an input positioning mechanism and an output positioning mechanism; the input positioning mechanism is used to place the workpiece to be polished, and the output positioning mechanism is used to place the polished workpiece.
[0023] Furthermore, the positioning system also includes a positioning detection device for controlling the placement height positions of the workpiece to be polished and the polished workpiece.
[0024] To achieve automatic workpiece displacement, the horizontal position accuracy of two aspects must be guaranteed: the clamping assembly must strictly ensure the horizontal position accuracy, and the placement of the workpiece in the input and output positioning mechanisms must also strictly ensure the horizontal position accuracy. Even the slightest deviation in either aspect will directly affect the smooth operation of the automatic edge grinding line, directly disrupting the line rhythm and causing significant losses.
[0025] Therefore, the input positioning mechanism and the output positioning mechanism are respectively provided with positioning detection devices for detecting the workpiece placing height of the input positioning mechanism and the output positioning mechanism respectively, and the workpiece placing position needs to be parallel to the ground.
[0026] In some modes, the workpiece is a mold pressing tray, and the input positioning mechanism and the output positioning mechanism are stacked with a plurality of mold pressing trays. When a mold pressing tray on the input positioning mechanism is removed, the height of the input positioning mechanism is inevitably lowered. If the remaining mold pressing trays are not moved upward in time to maintain the original height, the first clamping assembly cannot successfully grab the mold pressing tray, which affects the overall progress. Therefore, the positioning detection device needs to detect the stacking height of the mold pressing tray to be polished in the input positioning mechanism in time, and needs to be adjusted in time, so that the first clamping assembly can successfully grab the mold pressing tray each time and place it in the automatic edge grinding mechanism.
[0027] Meanwhile, when a mold pressing tray on the output positioning mechanism is moved in, the height of the output positioning mechanism is inevitably increased. If the mold pressing tray is not moved downward in time to maintain the original height, the second clamping assembly will collide with the mold pressing tray when it goes down, which will cause damage to the second clamping assembly, and even serious safety accidents may occur. Therefore, the positioning detection device needs to detect the stacking height of the mold pressing tray that has been polished in the output positioning mechanism in time, and needs to be adjusted in time, so that the second clamping assembly can successfully place the mold pressing tray that has completed polishing to the output positioning mechanism each time.
[0028] Further, the input positioning mechanism and the output positioning mechanism are respectively provided with an up-down movement power source for controlling the height of the input positioning mechanism and the output positioning mechanism, so as to control the placing height position of the workpiece to be polished and the workpiece that has been polished.
[0029] Further, the input positioning mechanism and the output positioning mechanism are respectively provided with a base plate, a traction chain, a gear and a limiting block. The base plate is used for placing the workpiece, and the traction chain and the gear are respectively connected with the base plate. The gear is used for controlling the base plate to remain horizontal. The limiting block is arranged on the base plate and is used for limiting the placing position of the workpiece.
[0030] In some modes, the traction chain has four traction chains, which are respectively arranged on both sides of the base plate, two on each side, for smoothly pulling the base plate to move up and down. One end of each traction chain is connected with the base plate, and the other end is connected with a cross beam in the frame. The traction chain pulls the base plate to move up and down through the rotation of the first gear. Meanwhile, a second gear is connected with the base plate, and the second gear is also connected with the bottom of the base plate. When the second gear rotates, it drives the base plate to move up and down along the base bar.
[0031] The second gear is provided with sawteeth uniformly, and is provided with a base strip transmission gear matched with the gear to transmit the rotation distance, and one rotation is equivalent to a height of about 1cm, that is, the one side of the base plate is raised by about 1cm.
[0032] The traction chains and the first gears are respectively located at two sides of the base plate and respectively pull two sides of the base plate, when the traction chains and the first gears pull the base plate upward, the second gear and the base strip pull one end of the base plate upward, if the traction chains and the first gears pull upward too fast or the speeds of the two traction chains are inconsistent, the base plate is inclined, the cooperation process of the second gear and the base strip is loose, the second gear is accelerated to rotate, the one end of the base plate is also accelerated to rise, so that the base plate always keeps horizontal. Through the perfect cooperation of the gear and the traction chain, the upper planes of the base plate and the overlying mold pressing trays are kept on a horizontal line, and the whole is uniformly raised or lowered.
[0033] In some modes, the mold pressing trays are overlying on the base plate of the input positioning mechanism, the specific placement position of the mold pressing trays is limited on the specific position by the limiting block, when the uppermost mold pressing tray is removed by the first clamping assembly, the overall height is lowered, the positioning detection device sends an indication, the traction chain pulls the base plate to move upward, the gear starts to rotate to control the speed of the base plate moving upward and keep the whole of the base plate and the mold pressing trays on a horizontal plane.
[0034] In some modes, the area of the base plate is larger than the mold pressing tray, so when the mold pressing tray is placed on the base plate of the input positioning mechanism, the deviation of the placement position of the mold pressing tray is prone to occur, which directly affects the subsequent automatic displacement and automatic polishing effect. Through the limiting block arranged on the base plate, the mold pressing tray needs to be placed in the limiting block when being placed on the base plate, so that the position of the mold pressing tray can be quickly and accurately limited, thereby simply and efficiently solving the problem.
[0035] Further, the automatic edge grinding mechanism is located at the middle position of the frame body, and the automatic displacement mechanism is arranged on the left side and the right side of the frame body.
[0036] Further, the workpiece comprises a mold pressing tray. Since the mold pressing tray after pressing has edge burrs, the edge of the mold pressing tray needs to be automatically ground.
[0037] In another aspect, the utility model provides an automatic edge grinding method of a mold pressing tray, which comprises the following steps:
[0038] (1) placing the mold pressing tray in the input positioning mechanism of the automatic displacement mechanism, the input positioning mechanism adjusts the position height of the mold pressing tray by controlling the height of the base plate;
[0039] (2) the first clamping assembly grabs the molded tray and places it into the automatic edging mechanism, and the automatic edging mechanism automatically edges it;
[0040] (3) after the automatic edging is completed, the second clamping assembly grabs the molded tray and places it into the output positioning mechanism, and the output positioning mechanism adjusts the position height of the molded tray by controlling the height of the base plate.
[0041] Further, the method comprises the following steps:
[0042] (1) the molded tray is placed in the input positioning mechanism of the automatic displacement mechanism, and the input positioning mechanism adjusts the position height of the molded tray by controlling the height of the base plate;
[0043] (2) the first clamping assembly moves downward, grabs the molded tray, moves to above the automatic edging mechanism, moves downward and places the molded tray into the automatic edging mechanism, and the automatic edging mechanism automatically edges it;
[0044] (3) after the automatic edging is completed, the second clamping assembly moves to above the automatic edging mechanism, moves downward, grabs the molded tray, moves to above the output positioning mechanism, moves downward and places the molded tray into the output positioning mechanism, and the output positioning mechanism adjusts the position height of the molded tray by controlling the height of the base plate.
[0045] In some modes, the position height of the molded tray in the input positioning mechanism, the position height of the molded tray in the automatic edging mechanism and the position height of the molded tray in the output positioning mechanism are consistent.
[0046] The utility model has the following beneficial effects:
[0047] (1) the automatic edging device of the molded tray provided by the utility model realizes full-process automatic edging control of the molded tray through close cooperation of the automatic edging mechanism and the automatic displacement mechanism, remarkably improves edging efficiency and is green, safe and environmentally friendly;
[0048] (2) the accuracy of the horizontal moving position of the clamping assembly, the accuracy of the horizontal moving position of the workpiece placed in the input positioning mechanism and the output positioning mechanism are guaranteed, so that the automatic displacement of the workpiece is accurately realized, the workpiece is prevented from being stuck, skewed or impacted during the movement, and the smooth progress of the full-automatic assembly line is guaranteed;
[0049] (3) the belt, the belt pulley and the moving track are arranged for the movement of the clamping assembly, and the combination of the belt, the belt pulley and the moving track provides stable double insurance for repeated horizontal movement of the clamping assembly, and ensures the accuracy of the horizontal moving position;

[0053] (7) The automatic control is realized, the labor cost is reduced, the grinding efficiency is improved, and the green environmental protection is realized.
[0054] Detailed description
[0055] Workpiece to be ground
[0056] The workpiece to be ground can be any product that needs to be ground, and the material thereof can be wood, plastic, metal or a product prepared by mixing a plurality of different materials, and the shape thereof can be any shape, as long as the size can cooperate with the automatic grinding mechanism to be ground. When the surface or edge of the product is rough, the automatic grinding mechanism provided by the utility model can be used for grinding to make the surface of the product smoother, facilitate use, or improve the aesthetic degree and user experience.
[0057] In some modes, the workpiece to be ground includes a mold pressing tray. The mold pressing tray is usually made of straw, branch, wood chip, bamboo chip, bamboo wood fertilizer and the like from recyclable resources, and is usually prepared by hot pressing and the like. The raw material is simple and low in cost, and is safe and environmentally friendly. There are many burrs on the outer edge surface of the mold pressing tray, and the edge of the mold pressing tray needs to be ground.
[0058] Automatic displacement mechanism
[0059] The automatic displacement mechanism is an indispensable part of realizing automatic grinding of the workpiece. The workpiece is automatically moved and placed into the base of the automatic grinding mechanism to ensure the accuracy of the placing position. The automatic grinding process cannot be affected by the deviation of the placing position. After the automatic grinding is completed, the workpiece is removed from the automatic grinding mechanism, and a new workpiece is placed into the automatic grinding mechanism. The automatic placing, automatic removing and automatic placing again process must be carried out in order and cannot be affected by each other. Moreover, the subsequent process cannot be affected by the incorrect placing of the placing and removing positions.
[0060] The automatic displacement is achieved by the clamping mechanism, and the shape of the clamping mechanism needs to be matched with the shape of the workpiece. For example, when the workpiece is a molded tray, the clamping mechanism needs to have a base and a clamping piece. The base is matched with the shape of the molded tray, which can improve the stability of the clamping process. When the molded tray is square, the base can be square. When the molded tray is circular, the base is preferably circular. The clamping piece is arranged around the outer periphery of the base, is rectangular and has a certain arc, can fit the edge of the molded tray, and can more stably clamp the molded tray. The number of clamping pieces can be adjusted according to the volume, weight, edge number and the like of the molded tray, as long as the clamping process can be balanced and the stable grabbing can be achieved. Of course, if the workpiece is other small objects, the clamping structure can also be clamped only by the clamping piece.
[0061] In order to accurately place the molded tray after clamping, in addition to making the shape of the clamping mechanism fit the molded tray and stably clamp it, the accurate design of the running track of the clamping mechanism must also be ensured. The running track can be combined in different forms such as chain, slider, pulley and slide rail, to ensure the accuracy of the running path and direction of the clamping mechanism after clamping the molded tray. The size, height and running track of the running track can be reasonably set according to the size of the workpiece, the placement position and the like.
[0062] The input positioning mechanism and the output positioning mechanism are respectively used to control the placement position and the placement height of the input and output molded trays. The number of clamping mechanisms can be one or more. When the number of clamping mechanisms is one, the clamping mechanism is first located above the input positioning mechanism at a certain height. When the molded tray needs to be grabbed, the clamping mechanism descends. The descending distance needs to be integrated with the clamping mechanism to contact and grab the molded tray. Then the clamping mechanism carrying the molded tray ascends to a certain height and moves above the automatic edge grinding mechanism. The clamping mechanism descends and accurately places the molded tray into the tray base of the automatic edge grinding mechanism, and makes the protrusions at the bottom of the tray and the grooves on the base completely match, so that the position of the molded tray is accurately fixed. The clamping mechanism ascends and starts automatic edge grinding. After edge grinding, the clamping mechanism descends again to grab the molded tray, ascends, then moves above the output positioning mechanism, and the clamping mechanism descends to place the molded tray into the output positioning mechanism. Then the clamping mechanism needs to run back to the input positioning mechanism.
[0063] It can be understood that the number of clamping mechanisms increases, the whole clamping process can be more efficient, but the number of clamping mechanisms increases, the difficulty of controlling different clamping mechanisms to keep synchronous operation increases, and the accuracy of displacement and grabbing is higher. The utility model optimally adopts two clamping mechanisms, which are respectively used for grabbing the workpiece to be polished from the input positioning mechanism and placing it into the automatic edge grinding mechanism, and grabbing the workpiece that has completed polishing from the automatic edge grinding mechanism and placing it into the output positioning mechanism. The adoption of two clamping mechanisms can significantly improve the efficiency of grabbing and displacement and speed up the automatic process, but the simultaneous control of the two clamping mechanisms increases the control difficulty, that is, it is necessary to ensure synchronization and prevent mutual influence. The utility model improves the structures of the moving track and the positioning mechanism, so that the moving track can accurately control the displacement of the clamping mechanism, and the positioning mechanism can accurately position, thereby enabling the two clamping mechanisms to complete the displacement and accurate position placement of the mold tray when the moving track and the positioning mechanism are used in combination, and ensuring the smooth progress of the automatic process.
[0064] In some ways, the positioning device can also not be provided, that is, the height of the mold tray at the input and output positions is not positioned and limited, and only when the clamping is performed, the distance of the downward movement of the clamping mechanism is adjusted each time. If the number of mold trays is large and the position placement is high, the downward movement distance of the clamping mechanism is short, if the number of mold trays is small and the position placement is low, the downward movement distance of the clamping mechanism is long. Such a setting can also achieve the same effect, but higher requirements are put forward for the adjustment of the downward movement distance of the clamping mechanism, and the difficulty increases. The utility model optimally selects the placement height of the mold tray at the input and output positions by the positioning mechanism, so that the distance of the downward movement of the clamping mechanism is certain each time. In this way, the structure setting can be simpler, and the automatic and accurate displacement of the mold tray can be realized in the simplest way, and the cost is also lower.

The horizontal moving power source 7 comprises a belt 21 and a belt pulley 22; the belt pulley 22 drives the belt 21 to move; the upper end of the clamping assembly 5 is fixed on the belt 21 and can move left and right horizontally along with the belt 21. The design of the moving track 6 can help to stabilize the moving direction of the clamping assembly 5 and prevent the position from deviating; the combination of the belt 21 and the moving track 6 provides double insurance for the repeated horizontal movement of the clamping assembly 5 and ensures the accuracy of the horizontal moving position.
[0082] As Figure 2 , 5The automatic displacement mechanism 2 also includes a positioning system 23, which includes an input positioning mechanism 24 and an output positioning mechanism 25. The input positioning mechanism 24 is used to place the workpiece 4 to be polished, and the output positioning mechanism 25 is used to place the polished workpiece 4. The positioning system 23 also includes a positioning detection device 27 for controlling the placement height of the workpiece 4 to be polished and the polished workpiece 4. To achieve automatic displacement of the workpiece 4, the accuracy of the horizontal movement position must be guaranteed in two aspects: on the one hand, the clamping assembly 5 must strictly ensure the accuracy of the horizontal movement position, and on the other hand, the placement of the workpiece 4 in the input positioning mechanism 24 and the output positioning mechanism 25 must also strictly ensure the accuracy of the horizontal movement position. Any slight deviation in either aspect will directly affect the smooth operation of the automatic edge grinding line, directly disrupt the line's rhythm, and cause significant losses. Therefore, both the input positioning mechanism 24 and the output positioning mechanism 25 are equipped with a positioning detection device 27, which is used to detect the placement height of the workpiece in the input positioning mechanism 24 and the output positioning mechanism 25, respectively. At the same time, the placement position of the workpiece 4 must also be parallel to the ground. In this embodiment, the workpiece 4 is a molded tray 11, and both the input positioning mechanism 24 and the output positioning mechanism 25 neatly stack multiple molded trays 11. When a molded tray 11 is removed from the input positioning mechanism 24, its height inevitably decreases. If the remaining molded trays 11 are not promptly moved upward to maintain their original height, the first clamping assembly 7 will be unable to smoothly grasp the molded tray 11, affecting overall progress. Therefore, the positioning detection device 27 must promptly detect the stacking height of the molded trays 11 to be polished in the input positioning mechanism 24 and make timely adjustments to ensure that the first clamping assembly 7 can successfully grasp each molded tray 11 and place it into the automatic edge grinding mechanism 3. Furthermore, when a molded tray 11 is added to the output positioning mechanism 25, its height inevitably increases. If the molded tray 11 is not promptly moved downward to maintain its original height, the second clamping assembly 8 will collide with the molded tray 11 during its downward movement, causing damage to the second clamping assembly 8 and potentially even a serious safety accident. Therefore, the stacking height of the edge-milled molded tray 11 in the output positioning mechanism 25 must be detected in time by the positioning detection device 27, and adjusted in time so that the second clamping assembly 8 can successfully place the edge-milled molded tray 11 into the output positioning mechanism 25 every time.
[0083] Preferably, the input positioning mechanism 24 and the output positioning mechanism 25 are both provided with a power source for up-and-down movement, which is used to control the height of the input positioning mechanism 24 and the output positioning mechanism 25, so as to control the placement height position of the workpiece 4 to be polished and the workpiece 4 that has been polished. The input positioning mechanism 24 and the output positioning mechanism 25 are both provided with a base plate 28 for placing the workpiece 4, a traction chain 29 and a gear 30 connected with the base plate 28 respectively, and a limiting block 31 arranged on the base plate 28 for limiting the placement position of the workpiece 4. One end 291 of each traction chain 29 is connected with the base plate 28, and the other end 292 is connected with a crossbeam 293 in the frame body. The traction chain 29 drives the up-and-down displacement of the base plate 28 through the rotation of the first gear 301 on the intermediate telescopic rod. Meanwhile, a second gear 302 is connected with the base bar 32, and the second gear 302 is also connected with the bottom of the base plate 28. When the second gear 302 rotates, it drives the base plate 28 to displace up and down along the base bar 32. The second gear 302 is uniformly provided with sawteeth, and the base bar 32 is also provided with a transmission gear matched with the sawteeth. Each rotation of the transmission gear corresponds to a height of about 1 cm, that is, the one side of the base plate 28 is raised by about 1 cm. The traction chain 29 and the first gear 301 are respectively located on the two sides of the base plate 28 and drive the two sides of the base plate 28 respectively. When the traction chain 29 and the first gear 301 drive the base plate 28 upward, the second gear 302 and the base bar 32 drive one end of the base plate 28 upward. If the traction chain 29 and the first gear 301 drive upward too fast, or the speeds of the two traction chains 29 are inconsistent, the base plate 29 will be inclined. In this case, the cooperation between the second gear 302 and the base bar 32 will be loose, which will accelerate the rotation of the second gear 302 and the rising of the one end of the base plate 28, so that the base plate 28 always remains horizontal. Through the perfect cooperation between the gear 30 and the traction chain 29, the upper surface of the base plate 28 and the mold pressing tray 11 stacked above the base plate 28 always remain on a horizontal line and rise or fall uniformly.
[0084] Preferably, the area of the base plate 28 is larger than the molded tray 11. Therefore, when the molded tray 11 is placed on the base plate 28 of the input positioning mechanism 24, the molded tray 11 is prone to positional deviation. This deviation directly affects the subsequent automatic displacement and automatic polishing effects. By providing a limiting block 31 on the base plate 28, the molded tray 11 needs to be placed against the limiting block 31 when it is placed on the base plate 28. This can quickly and accurately determine the position of the molded tray 11, thus solving this problem simply and efficiently.
[0085] Preferably, the position height of the molded tray 11 in the input positioning mechanism 24, the position height of the molded tray 11 in the automatic edge grinding mechanism 3, and the position height of the molded tray 11 in the output positioning mechanism 25 are all consistent. When the heights are consistent, the clamping assembly 5 (including the first clamping assembly 7 and the second clamping assembly 8) can move the same distance each time it descends, accurately grasping the molded tray 11 and accurately shifting it.
[0086] like Figure 1 Preferably, the machine further includes a frame 33, with the automatic edging mechanism 3 located in the middle 34 of the frame 33, and the automatic displacement mechanism 2 located on the left and right sides of the frame 33. The frame 33 can provide support for the automatic edging mechanism 3 and the automatic displacement mechanism 2. In this embodiment, the workpiece 4 is primarily a molded pallet 11. Since the molded pallet 11 has burrs on its edges after being pressed, automatic edging of the edges of the molded pallet 11 is required.
[0087] Example 2: A molded pallet edge grinding machine
[0088] The molded pallet edge grinding machine 1 provided in this embodiment ( Figure 1 ) includes the automatic displacement mechanism 2 and the automatic edge grinding mechanism 3 as shown in Example 1, the automatic edge grinding mechanism structure 3 is as shown in Figures 6-8 As shown, the machine comprises a base 35 and a grinding component 36; the base 35 is used to secure the workpiece 4 to be ground, and the grinding component 36 is used to automatically grind the workpiece 4 to be ground; the grinding component 36 is connected to the base 35 via a connector 37. In this embodiment, the workpiece 4 to be ground is a molded tray 11. Because the molded tray 11 has burrs on its edges after being pressed, it is necessary to perform automatic edge grinding on the edges of the molded tray 11.
[0089] like Figure 6The base 35 is provided with a moving part 26, which can drive the base 35 to move, thereby driving the workpiece 4 to be polished to move synchronously. The moving mode of the base 35 is horizontal rotation, and the polishing part 36 is slidably connected to the slide rail 38 below the base 35 through the connecting piece 37. The connecting piece 37 comprises a connecting rod 39 and a sliding block 40, and the sliding block 40 is connected to the slide rail 38 below the base 35. When the base 35 rotates, the sliding block 40 of the polishing part 36 slides in the slide rail 38. Through the design of the slide rail 38 and the sliding block 40, the base 35 can rotate, and the polishing part 36 can be kept as still as possible, and the polishing part 36 and the base 35 still maintain the same distance. The shape of the slide rail 40 matches the shape of the base 35, for example, the base 35 is a square (with rounded corners), and the slide rail 49 is also a square (with rounded corners) with a size smaller than the square of the base 35.
[0090] As Figure 7 Preferably, the sliding block 40 is a cylindrical structure 41, and the number of the cylindrical structures 41 is one or more. The cylindrical structure 41 is fixed through a center 42, and the cylindrical structure 41 can rotate freely around the center 42. The cylindrical structure 41 can rotate freely around the center. The free rotation of the cylindrical structure 41 around the center 42 can reduce the friction of the sliding block 40 in the slide rail 38, make the sliding of the sliding block 40 in the slide rail 38 more smooth, reduce the wear of each part caused by friction, and prolong the service life of each part. The number of the cylindrical structures 41 is preferably two. Controlling the number of the cylindrical structures 41 can improve the stability of the connection between the polishing part 36 and the base 35. When the sliding block 40 is connected by two cylindrical structures 41, compared with the case of one cylindrical structure 41, the stability of the connection can be significantly improved, but the number of the cylindrical structures 41 cannot be too much, such as three or more, which not only increases the cost, but also increases the difficulty of sliding, and even the sliding block 40 can be stuck in the slide rail 38 and difficult to move smoothly, so it is preferred to use two cylindrical structures 41 as the sliding block 40 for sliding connection.
[0091] The length of the connecting piece 37 determines the distance between the polishing part 36 and the base 35, which is preferably 5-20 cm, and most preferably 12 cm. That is, when the distance between the polishing part 36 and the base 35 is maintained at 12 cm, the contact and friction effect of the abrasive cloth 43 of the polishing part 36 with the edge of the molded tray 11 is the best, the edge polishing effect is the most appropriate, the edge polishing efficiency can be improved, and the product quality can be ensured.
[0092] As Figures 6-8The polishing part 36 is provided with a roller 44. During the edge polishing process, the roller 44 is pressed above the mold pressing tray 11 and kept rotating. During the edge polishing process, the mold pressing tray 11 is placed on the base 35, but is not fixed and is easy to vibrate or displace upward and downward during the rotation process driven by the base 35, which causes the deviation of the edge polishing position and affects the overall edge polishing effect. Therefore, during the rotation and edge polishing process of the mold pressing tray 11, corresponding parts need to be arranged to help fix the relative position of the mold pressing tray 11 to ensure that the edge position of the mold pressing tray 11 during the edge polishing process is accurate and is not easy to deviate. The roller 44 plays this role, and the roller 44 itself is also continuously rotating, so it can help stabilize the position of the mold pressing tray 11 and ensure that the mold pressing tray 11 is not hindered during the rotation process, improving the quality and efficiency of the edge polishing. The rotation speed of the roller 44 matches the rotation speed of the base 35.
[0093] The rotation speed of the roller 44 also has a very important influence on the edging effect. Since the molded tray 11 is polished by the polishing part 36, it is a polygon rather than a circle. If the friction or resistance between the roller 44 and the molded tray 11 is generated, the different edges of the molded tray 11 will be subjected to different friction or resistance, thus the edging effect will be uneven, which will seriously affect the product quality. When the rotation speed of the roller 44 is less than the rotation speed of the base 35, the edging effect will be poor; when the rotation speed of the roller 44 is greater than the rotation speed of the base 35, not only the friction will be increased, but also the molded tray 11 will be displaced, and the wear degree of the polishing part 36 will be increased; when the edge 19 of the molded tray 11 rotates to the position of the roller 44, since the distance between the roller 44 and the center of the molded tray 11 is shortened, the influence of the friction or resistance between the roller 44 and the molded tray 11 on the rotating centrifugal force will be increased; when the edge 45 of the molded tray 11 rotates to the position of the roller 44, since the distance between the roller 44 and the center of the molded tray 11 is lengthened, the influence of the friction or resistance between the roller 44 and the molded tray 11 on the rotating centrifugal force will be decreased. It can be seen that once the friction or resistance between the roller 44 and the molded tray 11 is generated, the edging effect will be uneven. Therefore, the rotation speed of the roller 44 must be matched with the rotation speed of the base 35. Here, the rotation speed matching does not mean that the rotation speed of the roller 44 is the same as the rotation speed of the base 35. In fact, the rolling diameter of the roller 44 is small, and the rotating diameter of the base 35 is relatively large. Therefore, the rotation speed matching is that when a point on the roller 44 contacts a point on the molded tray 11, the displacement of the point on the roller 44 after the contact is consistent with the displacement of the point on the molded tray 11 after the contact. In the embodiment, the diameter of the roller 44 is 15 cm, the diameter of the molded tray 11 is 198 cm, and when the rotation speed of the roller 44 is 580 rpm and the rotation speed of the molded tray 11 is 16 rpm, the friction or resistance between the roller 44 and the molded tray 11 can be reduced as much as possible. At the same time, the rotation speed matching of the roller 44 and the base 35 can not only reduce the friction, but also prolong the service life of the polishing part 36.
[0094] As Figure 8, the polishing part 36 is provided with a swing arm 46 for adjusting the position of the polishing part 36 to match the irregularly shaped base 35. The polishing part 36 is connected to the base 35 through a connecting piece 37, and the length of the connecting piece 37 determines the distance between the polishing part 36 and the base 35. The sliding block 40 on the connecting piece 37 can slide in the sliding rail 38 below the base 35, and through the design of the sliding rail 38 and the sliding block 40, the base 35 can be rotated while the polishing part 36 remains as still as possible, and the polishing part 36 and the base 35 still maintain the same distance. However, since the molded tray 11 is a polygon with edges 45, when the molded tray 11 is rotated from the edge 19 to the corner 45 aligned with the polishing part 36, the distance between the polishing part 36 and the center of the base 35 will inevitably increase, so the polishing part 36 cannot remain completely still in place and must be moved backward at this time to truly match the position of the corner 45 of the molded tray 11 and to edge the corner 45 of the molded tray 11. At this time, the swing arm 46 needs to be provided on the polishing part 36 to allow the polishing part 36 to move and adjust the distance between the center of the base 35 (the center of the base 35 is fixed) within a certain sector.
[0095] One end 47 of the swing arm 46 is fixed, and the other end 48 can drive the polishing part 36 to move forward and backward in the horizontal plane; the base 35 is a polygonal structure with corners, when the base 35 is rotated to the corner close to the polishing part 36, the polishing part 36 moves backward through the swing arm 46, and the distance between the polishing part 36 and the center of the base 35 becomes longer; when the base 35 is rotated to the edge of the polygon close to the polishing part 36, the polishing part 36 moves forward through the swing arm 46, and the distance between the polishing part 36 and the center of the base 35 becomes shorter. The molded tray 11 is a polygonal structure with corners, when the molded tray 11 is rotated with the base 35, if there is no swing arm 46 structure, the distance between the polishing part 36 and the center of the base 35 remains unchanged, then when the corner 45 of the molded tray 11 is turned to be edged, the position of the corner 45 of the molded tray 11 and the position of the polishing part 36 collide together, resulting in a part of the molded tray 11 unable to continue to be edged. Therefore, when the polishing part 36 edges the corner 45, a swing arm 46 is needed to change the distance between the polishing part 36 and the center of the base 35 at all times, so that the polishing part 36 and the corner 45 maintain a proper distance, thereby continuing the edging work.
[0096] During the rotation of the molded tray 11, the working process of the swing arm 46 is as follows Figure 9As shown, when the mold tray 11 is turned from the edge 19 (left) to the corner 45 (right), the swing arm 46 is horizontally turned outward by about 15 degrees, so that the polishing part 36 is moved backward to match the corner 45 of the mold tray 11. It can be seen that the design of the swing arm 46 can make the polishing part 36 suitable for various irregularly shaped bases 35 or mold trays 11, and suitable for various situations where the distance from the center of the base 35 changes, thereby widening the application range of the polishing part 36.
[0097] As shown in FIG. 1, the automatic edge polishing mechanism 3 comprises a base 35, a mold tray 11, a polishing part 36, an automatic displacement mechanism 2, and an automatic polishing mechanism 3. Figures 6-9 In the automatic edge polishing mechanism 3, the number of polishing parts 36 is two, which are arranged on both sides of the base 35. The arrangement of two polishing parts 36 can effectively utilize the space and improve the edge polishing efficiency.
[0098] Preferably, the polishing part 36 further comprises a sandpaper 43 for polishing the mold tray 11. The sandpaper 43 is detachably fixed on a support 51. The support 51 is provided with two upper and lower rollers 52, which are used to drive the sandpaper 43 to rotate, so as to polish the mold tray 11. The rotation speed of the roller 52 is consistent with the rotation speed of the base 35, which prolongs the service life of the sandpaper 43. The sandpaper 43 rolls with the roller 52, so as to realize rolling while polishing the mold tray 11. At the same time, the mold tray 11 is continuously rotated, which is equivalent to that the position of the mold tray 11 changes in the horizontal direction, and the position of the sandpaper 43 changes in the vertical direction. The combination of the multiple position changes can improve the polishing effect. In the automatic edge polishing mechanism 3, the base 35 is provided with a groove 53, which matches with a protrusion 54 at the bottom of the mold tray 11. When the mold tray 11 is placed on the base 35, the protrusion 54 enters the groove 53, and the mold tray 11 is positioned. The groove 53 of the base 35 can help to position and fix the mold tray 11, avoid improper position, and make the mold tray 11 rotate more stably when the base 35 rotates. The number of the groove 53 and the protrusion 54 is consistent, which is one or more, and is evenly arranged on the base 35 and the bottom of the mold tray 11 respectively. When the mold tray 11 is fixed on the base 35, the mold tray 11 should be fixed on the base 35 without moving during the polishing process, so that the polishing part 36 can uniformly polish the mold tray 11.
