Description

Technical Field

[0001] This utility model relates to the field of cutting board production and processing technology, and in particular to a cutting board production and processing equipment. Background Technology

[0002] Plastic cutting boards are primarily manufactured using injection molding. After molding, they need to be cooled, and then the cutting head needs to be cut.

[0003] Currently, cooling and cutting are two discontinuous processing steps. Typically, the cutting boards are collected after cooling before the cutting process begins, resulting in low processing efficiency. Furthermore, the current method of cooling cutting boards is generally natural cooling, which is not only inefficient and affects the overall processing efficiency of the cutting boards, but also causes the cutting boards to deform during the actual process. Due to factors such as internal stress during cooling, the cutting boards will warp and deform to varying degrees, leading to the generation of waste products. Utility Model Content

[0014] Preferably, the fixing component includes a third suction cup, a third driving member, a first fixing block, a fourth driving member, and a second fixing block. The third suction cup is embedded in the top surface of the support plate.

[0020] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0021] This invention utilizes a circulating water channel to allow cold water to enter the upper and lower pressure plates through the inlet, keeping the upper and lower pressure plates constantly cooled. This effectively cools the cutting board compared to existing natural cooling methods, significantly reducing the probability of warping and deformation. After the cutting board has cooled under pressure, the first driving component moves the upper pressure plate upward. The first robotic arm then drives the loading and unloading assembly to remove the cooled cutting board and place it on the support plate. Finally, the second robotic arm drives the cutting head assembly to cut off the excess material from the cutting board on the support mechanism, completing automated continuous processing. Compared to existing methods that involve collecting the naturally cooled cutting boards before cutting, this invention greatly improves processing efficiency. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0033] like Figures 1-8 As shown, this utility model provides a cutting board production and processing equipment, including an injection molding machine 10, a pressure holding mechanism 2, a support and fixing mechanism 9, a loading and unloading mechanism 3, and a cutting head mechanism 8;

[0034] Injection molding machine 10 is used for injection molding of cutting boards;

[0035] The pressure holding mechanism 2 includes a lower pressure plate 22, an upper pressure plate 23, a circulating water channel, and a first driving member 26 (the first driving member 26 here can be a cylinder). The upper pressure plate 23 is located above the lower pressure plate 22. The side walls of the upper pressure plate 23 and the lower pressure plate 22 are provided with at least one water inlet 24 and one water outlet 25. The upper pressure plate 23 and the lower pressure plate 22 are provided with a circulating water channel. The circulating water channel is connected to the water inlet 24 and the water outlet 25. The first driving member 26 drives the upper pressure plate 23 to move closer to or away from the lower pressure plate 22.

[0036] The support and fixing mechanism 9 includes a support plate 91 and a fixing component for fixing the cutting board;

[0037] The loading and unloading mechanism 3 includes a first robotic arm 301 and a loading and unloading assembly (the loading and unloading mechanism 3 can automatically load and unload the cutting board, avoiding the trouble of manual operation). The first robotic arm 301 is used to drive the loading and unloading assembly to grab the cutting board that has been injection molded by the injection molding machine 10 and place it on the lower pressure plate 22, and to grab the cutting board on the lower pressure plate 22 and place it on the support plate 91.

[0038] The cutting head mechanism 8 includes a second robot arm 801 and a cutting head assembly. The second robot arm 801 is used to drive the cutting head assembly to cut off the cutting head of the food on the upper cutting board of the supporting and fixing mechanism 9.

[0039] During the production and processing of the cutting board, the first robotic arm 301 drives the loading and unloading assembly to remove the cutting board, which has been injection molded on the injection molding machine 10, and place it on the lower pressure plate 22. Then, the first driving component 26 is adjusted to move the upper pressure plate 23 downward, so that it fits against the top surface of the cutting board and is pressed and fixed. Through the circulating water channel, cold water enters the upper pressure plate 23 and the lower pressure plate 22 through the water inlet 24, keeping the upper pressure plate 23 and the lower pressure plate 22 in a cooling state at all times. This effectively cools and lowers the temperature of the cutting board compared to the existing natural cooling, which can effectively reduce the occurrence of different temperatures on the cutting board. The probability of warping and deformation is greatly reduced, thus minimizing the generation of waste. After the cutting board is held under pressure and cooled, the first driving component 26 is adjusted to move the upper pressure plate 23 upward. The first robotic arm 301 drives the loading and unloading assembly to remove the cooled cutting board and place it on the support plate 91. Finally, the second robotic arm 801 drives the cutting head assembly to cut off the cutting head of the cutting board on the support fixing mechanism 9, thus completing automated continuous processing. Compared with the existing method of collecting the cutting boards after natural cooling and then cutting them, this method greatly improves processing efficiency.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, the cutting head assembly includes a support block 81, an elastic element 83, and a cutter 82. The cutter 82 is connected to one side of the support block 81 through the elastic element 83.

[0041] Since the length of the injection-molded cutting board may vary, with differences of up to 2mm, and since the travel path of the second robotic arm 801 is fixed, specifically, a vertical plate is fixedly installed on one side of the support block 81, and a sliding plate is slidably installed. An elastic element 83 (which can be a spring) is installed between the sliding plate and the vertical plate. A cutter 82 is fixedly installed at one end of the sliding plate. With this configuration, when the second robotic arm 801 moves the cutting head assembly, the cutter 82 first comes into horizontal contact with the outer edge of the cutting board, and then the cutter 82 is adjusted to cut the material along the outer edge of the cutting board, thereby enabling the cutting of cutting boards of different sizes.

[0042] like Figure 3As shown, several first suction cups 101 are fixedly installed on the support block 81, and the first suction cups 101 and the cutter 82 are located on different sides of the support block 81.

[0043] By setting the first suction cup 101, after the cutting board head on the support plate 91 is cut off, the second robotic arm 801 is adjusted to drive the support block 81 to move, thereby driving the first suction cup 101 to move, thus completing the picking up of the cutting board with the cut-off head. After picking up the material, it is transferred to the first conveyor belt 11, thus completing the automatic unloading of the cutting board on the support block 81. By placing the first suction cup 101 and the cutter 82 on different sides of the support block 81, it can be ensured that when the first suction cup 101 adsorbs and fixes the cutting board, the cutter 82 will not come into contact with the cutting board and cause damage.

[0044] like Figure 2 and Figure 8 As shown, it also includes a second driving component 27 (the second driving component 27 here can be a cylinder). The second driving component 27 drives the lower pressure plate 22 to be located directly below or offset from the upper pressure plate 23. By adjusting the second driving component 27 to drive the lower pressure plate 22 to move horizontally so that it is offset from the upper pressure plate 23, it is convenient to place the cutting board that needs to be pressure-held on the lower pressure plate 22 so that the loading and unloading components will not collide with the upper pressure plate 23, reducing the stroke of the upper pressure plate 23 moving up and down.

[0045] The loading and unloading assembly includes a mounting frame 31, a second suction cup 32, and a clamping unit 33. The mounting frame 31 is provided with a number of second suction cups 32 and clamping units 33. (The specific clamping unit 33 includes a drive cylinder and a clamping plate. By adjusting the drive cylinder, the two clamping plates are moved closer to each other to complete the clamping and fixing of the cutting board.)

[0046] When it is necessary to load and unload the cutting board, the robotic arm is adjusted to drive the loading and unloading components to move until the second suction cup 32 picks up and fixes the cutting board. At the same time, the clamping unit 33 is adjusted (i.e., the drive cylinder is adjusted to drive the two clamping plates to move closer to each other), thereby completing the stable fixing of the cutting board, that is, the stable loading and unloading work.

[0047] like Figure 5 and Figure 6 As shown, the fixing component includes a third suction cup 92, a third driving member, a first fixing block 93, a fourth driving member, and a second fixing block 94. The third suction cup 92 is embedded in the top surface of the support plate 91. The third driving member is used to drive the first fixing block 93 to move closer to or away from the top surface of the support plate 91. The fourth driving member drives the second fixing block 94 to abut against the side wall of the cutting board.

[0048] This example uses two cutting boards as a set. After the two cutting boards are injection molded and removed from the injection molding machine 10 (e.g.) Figure 9As shown, two cutting boards have connecting heads on one side facing each other, and two cutting boards also have connecting heads on the opposite side. Therefore, four support plates 91 are set here, with two support plates 91 forming a group, corresponding to four sets of clamping units 33. There is a gap between the two support plates 91, and the second fixing block 94 is located in the gap between the two support plates 91. When the two cutting boards are respectively placed on the two support plates 91, the two second fixing blocks 94 are first moved away from each other by adjusting the fourth driving component so that they abut against the opposite side of the two cutting boards, thereby completing the initial fixing of the cutting boards. Then, the cutting boards are attracted and fixed by the third suction cup 92. Finally, the third driving component is adjusted to drive the first fixing block 93 to move down and press the cutting boards tightly and fix them. Through the above three positioning and fixing structures, the cutting boards can be stably fixed, that is, to ensure the stable operation of the subsequent cutting head.

[0049] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a first conveyor belt 11 and a second conveyor belt 12. The first conveyor belt 11 is located above the second conveyor belt 12. The support and fixing mechanism 9 also includes a fixing frame 901. The fixing frame 901 is provided with a guide component 902. The guide component 902 is located below the support plate 91. The discharge end of the guide component 902 is connected to the second conveyor belt 12.

[0050] The guide component 902 here is a guide plate that is inclined downward toward the second conveyor belt 12. After the cutter 82 cuts off the scrap on the cutting board, the scrap is guided to the second conveyor belt 12 through the guide plate and then conveyed to the designated place. This makes it convenient for people to collect and clean up the scrap in time, and avoids the scrap falling near the fixed frame 901 and the cutting head assembly. This would prevent the scrap from falling and causing certain safety hazards when people clean it up, or the trouble of having to wait until the machine is stopped to clean it up, which would lead to too much scrap accumulation.

[0051] like Figure 7 and Figure 9 As shown, the top surface of the lower pressure plate 22 is provided with a limiting mechanism, which includes a first limiting block 6 that limits the width of the cutting board and a second limiting block 7 that limits the length of the cutting board.

[0052] This example uses two cutting boards as a set. After the two cutting boards are injection molded and removed from the injection molding machine 10 (e.g.) Figure 9 As shown, two cutting boards have connecting heads on opposite sides. When the loading and unloading mechanism 3 is driven by a robotic arm to place the two cutting boards on the lower pressure plate 22, the first limiting block 6 abuts against the long side of the cutting board, and the two second limiting blocks 7 abut against the opposite side (i.e., the short side) of the two cutting boards respectively. This ensures that after the cutting boards are placed on the lower pressure plate 22, the cutting boards on the lower pressure plate 22 will not move during the process of adjusting the second driving component 27 to drive the lower pressure plate 22 to be directly below the upper pressure plate 23, thus ensuring that the cutting boards can stably perform the pressure holding work in the future.

[0053] like Figure 7 As shown, the top surface of the lower pressure plate 22 is symmetrically provided with several first sliding grooves 61 parallel to the width direction of the lower pressure plate 22 and several second sliding grooves 71 parallel to the length direction of the lower pressure plate 22 on both sides along its length direction. A first limiting block 6 is provided in the first sliding groove 61. The length of the first sliding groove 61 is greater than the length of the first limiting block 6, so as to ensure that the first limiting block 6 can slide in the first sliding groove 61. A second limiting block 7 is provided in the second sliding groove 71 (two second limiting blocks 7 are provided in the second sliding groove 71, and the two second limiting blocks 7 are opposite each other and respectively abut against the opposite side of the cutting board). The length of the second sliding groove 71 is greater than the length of the two second limiting blocks 7, so as to ensure that the second limiting blocks 7 can slide in the second sliding groove 71. Specifically, the first limiting block 6 and the second limiting block 7 can be locked and fixed in the first sliding groove 61 and the second sliding groove 71 respectively by screws.

[0054] With this setting, the distance between the first limiting block 6 and the second limiting block 7 can be adjusted, thereby limiting and fixing cutting boards of different lengths and widths;

[0055] Additionally, it should be noted that when the cutting board is on the lower pressure plate 22, the height of the first limiting block 6 and the second limiting block 7 is not higher than the height of the cutting board, or the upper pressure plate 23 is provided with a clearance groove that matches the first limiting block 6 and the second limiting block 7, so as to ensure that the top and bottom surfaces of the cutting board are completely in contact with the upper pressure plate 23 and the lower pressure plate 22 respectively.

[0056] like Figure 1 , Figure 4 , Figure 8 and Figure 9 As shown, it also includes a housing 1. The housing 1 has four side slots on one side from top to bottom. Each side slot is equipped with a pressure holding mechanism 2. There are four loading and unloading components, and each pair of loading and unloading components forms a group.

[0057] With this setup, the robotic arm can be used to drive the loading and unloading mechanism 3 to remove the cutting boards that have been held and cooled by the pressure holding mechanism 2 in the two side slots. After removing the two sets of four (connected in pairs) cutting boards that have been injection molded by the injection molding machine 10, they are placed in the pressure holding mechanism 2 in the two side slots respectively. Then, the cutting boards that have been held and cooled by the pressure holding mechanism 2 in the other two side slots are unloaded. The two cutting boards are used as a group to achieve continuous loading and unloading, which is highly efficient.

[0058] like Figure 2As shown, the pressure holding mechanism 2 also includes a support frame 21, on which a photoelectric sensor 5 (specifically, a Panasonic CX411 model can be used) is provided. A through hole 221 is opened on the top surface of the lower pressure plate 22. The photoelectric sensor 5 is located below the lower pressure plate 22 (specifically, the lower pressure plate 22 is slidably mounted on the support frame 21 via a slide rail 4). When the lower pressure plate 22 is located directly below the upper pressure plate 23, the through hole 221 is directly opposite to the photoelectric sensor 5.

[0059] When the cutting board is placed on the lower pressure plate 22, and the lower pressure plate 22 is driven to be directly below the upper pressure plate 23 by adjusting the second driving component 27, the cutting board on the lower pressure plate 22 can be detected by the photoelectric sensor 5. The photoelectric sensor 5 sends a signal to the controller, and the controller controls the first driving component 26 to drive the upper pressure plate 23 to move down to maintain pressure on the cutting board, thus avoiding the upper pressure plate 23 and the lower pressure plate 22 being out of pressure.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
