Description

Technical Field

[0001] The present disclosure relates to the field of tableware, and in particular to an oil pad, an oil pad manufacturing mold and an oil pad manufacturing method. Background Art

[0002] At present, in cooking, such as frying, grilling, etc., waste oil is inevitably generated. These waste oils will not only destroy the freshness of food, but repeated use of waste oil will also cause harm to the human body. The most common practice is to pour out the waste oil and clean the utensils, but this procedure is cumbersome, time-consuming and water-consuming. In order to clean the waste oil, chemical cleaners such as detergents are generally required. If the cleaning is not in place, the chemical cleaners will affect the taste of the food and cause harm to the human body. Especially for restaurants that operate externally, if the service staff must spend time cleaning the waste oil from the barbecue after the consumer has finished the meal, it will lead to a decrease in the turnover rate of the restaurant and increase the manpower and time costs of the restaurant.

[0058] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0059] Oil pad:

[0060] Figure 1 is a schematic diagram of an oil pad embodiment of the present disclosure, such as Figure 1As shown, an oil pad includes: a main body 1 and an oil outlet 2, the main body 1 includes a first end 3 and a second end 4, the first end 3 and the second end 4 are arranged opposite to each other, and the main body 1 is formed by the first end 3 extending along the outer edge of the oil outlet 2 to the second end 4; when in use, the first end 3 and the second end 4 are seamlessly joined. When the main body is spread out along a plane, there is a gap between the first end 3 and the second end 4, and the first end 3 and the second end 4 are adjusted so that the first end 3 and the second end 4 are seamlessly joined, or as seamlessly joined as possible to avoid direct contact of waste oil with cooking utensils. In actual use, when the main body 1 is laid on a cooking utensil, such as an iron plate or a barbecue plate for cooking, the oil outlet 2 faces the oil leakage port of the cooking utensil. When cooking, place food on the main body 1, and the waste oil generated during the cooking process flows into the oil leakage port through the oil outlet 2 and is discharged. In some embodiments, the shape of the main body 1 is not limited to the square shown in this embodiment, and can also be Figure 2 The rectangle shown or Figure 4 round as shown, or any shape that fits the cooking utensil.

[0061] In one of the embodiments, the oil pad of the present invention is used in conjunction with a barbecue grill. The oil pad is directly placed on the grilling plate of the barbecue grill, with the oil outlet 2 facing the oil leakage port of the barbecue grill, the oil leakage port being lower than the grilling plate, and the grilling plate of the barbecue grill extending upward from the oil leakage port to the edge of the grilling plate. To further fix the oil collecting pad, the oil plug of the barbecue grill is directly inserted into the oil leakage port of the barbecue grill and the oil pad is further fixed on the grilling plate. Waste oil and waste water generated by food flow downward along the oil pad to the oil leakage port. When cleaning and replacing the oil pad, the oil plug is directly removed, the oil pad is withdrawn, and a new oil pad is replaced.

[0062] In other embodiments, if the oil leakage port of the cooking utensil is lower than the plane of the cooking area, when using the oil pad of the present disclosure, since the main body 1 is laid on the cooking utensil, the height of the oil outlet 2 is lower than the height of the main body 1, and the waste oil generated by cooking food on the main body 1 naturally gathers to the oil outlet and flows into the oil leakage port of the cooking utensil through the oil outlet 2, and then is collected by other waste oil collecting devices. Whether for families or restaurants, there is no need for manpower to clean and drain the cooking utensils, especially for commercial occasions, before the next table of guests dine, the used oil pad can be directly removed and replaced with a new one, without spending manpower to clean and delay the dining time of consumers. During the dining process, the oil pad can also be replaced at any time to avoid the waste oil affecting the freshness of the food.

[0063] Figure 2 This is a schematic diagram of an oil pad embodiment of the present invention. The main body 1 of the present embodiment is rectangular, and a gap is left between the first end 3 and the second end 4. In this way, when the main body 1 is laid along the cooking utensil, the first end 3 and the second end 4 can be respectively arranged along the oil leakage port of the cooking utensil, so that the oil outlet 2 of the oil pad of the present invention and the oil leakage port of the cooking utensil completely overlap, and can be used with cooking utensils of different shapes.

[0064] Figure 3 Schematic diagram of an oil pad embodiment of the present disclosure, such as Figure 3 As shown, in order to better prevent the oil pad from leaking, the first end 3 and the second end 4 can be partially overlapped to avoid a gap between the first end 3 and the second end 4 to prevent waste oil from leaking onto the cooking utensil. The oil outlet of the oil pad disclosed in the present invention can be in any shape, such as circular, rectangular, square or any irregular shape. In actual use, the size of the overlapping area of ​​the first end 3 and the second end 4 or the shape of the oil outlet 2 formed after the overlap is adjusted to be polygonal or circular. For example, the original shape of the oil outlet 2 of the oil pad is rectangular. In actual use, the first end 3 and the second end 4 can also be adjusted to make the actual oil outlet 2 rectangular, square, circular or elliptical and other shapes, so that the oil outlet 2 is smaller than the oil leakage port of the cooking utensil to avoid the possibility of waste oil flowing into the cooking utensil.

[0065] In order to further prevent waste oil from leaking onto the cooking utensil, the overlapping area of ​​the first end 3 and the second end 4 is as large as possible to avoid oil leakage, but the cost will increase accordingly, so the shortest length L of the overlapping area of ​​the first end 3 and the second end 4 is set to at least 0.02 cm, which can reduce the cost as much as possible and avoid the slight displacement of the first end 3 and the second end 4 causing a gap. In other embodiments of the present disclosure, the shortest length of the overlapping area is 1 cm to 5 cm, preferably 2 cm.

[0066] Figure 4 Schematic diagram of an oil pad embodiment of the present disclosure. Figure 1 , Figure 2 and Figure 3 As shown, in order to prevent the oil accumulated on the oil pad from leaking to the edge, the edge of the main body 1 away from the oil outlet 2 is curled outward and upward along the radial direction of the oil outlet 2 to form a curling protrusion 5, and the distance between the curling protrusion 5 and the main body 1 is at least 0.02 cm. In this embodiment, the vertical height between the curling protrusion 5 and the main body 1 is at least 0.02 cm, preferably more than 0.05 cm, and more preferably 0.5 cm.

[0067] In order to make the oil pad of the present invention adaptable to cooking utensils of different shapes and different cooking purposes, the main body 1 of the oil pad of the present invention is made of flexible materials as much as possible, and can be folded or the first end 3 and the second end 4 can be overlapped as needed. The main body 1 of the present invention is preferably made of aluminum foil, which is light and easy to bend, and does not volatilize toxic gases during cooking, and is suitable for various cooking occasions, such as teppanyaki or barbecue. In other embodiments, the main body 1 can also be made of flexible materials, and the surface of the main body 1 that contacts the food is covered with aluminum foil to prevent the food from contacting highly volatile organic matter.

[0068] Oil pad making mold:

[0069] Figure 5 This is a schematic diagram of the three-dimensional structure of the oil pad manufacturing mold according to the embodiment of the present disclosure. Figure 6 This is a front view structural diagram of an oil pad manufacturing mold according to an embodiment of the present disclosure. Figure 7 AA is a schematic cross-sectional view of the oil pad manufacturing mold of the embodiment of the present disclosure, Figure 8 This is a front view structural cross-sectional schematic diagram of an oil pad manufacturing mold according to an embodiment of the present disclosure. In the schematic diagram, some array components are not shown to avoid obstruction.

[0070] Specifically, the embodiments of the present disclosure provide an oil pad manufacturing mold, which can be used to manufacture the oil pad of the aforementioned structure.

[0071] Specifically, for the conventional oil pad structure, the conventional implementation method is punching and forming. Specifically, considering that the oil pad structure of the embodiment of the present disclosure has a special oil outlet design, the punching and forming process of the oil pad is divided into two steps. The first punching and forming process processes the required oil outlet, and the second punching and forming process processes the required outer contour of the main body.

[0072] It should be noted that, since the first end and the second end of the oil pad of the embodiment of the present disclosure are seamlessly connected structures, the oil outlet is an open-loop contour accordingly. Therefore, the required overall outer contour structure of the oil pad can only be obtained by compounding the stamping contours of two stampings. In actual operation, the overall outer contour of the oil pad can be reasonably disassembled into two sections and processed by two punching and forming processes respectively to obtain better processing effects. In addition, considering that the outer ring contour of the main body of the embodiment of the present disclosure is provided with a curling protrusion, and there is no curling protrusion at the oil outlet position, the two punching and forming processes can well meet its structural requirements.

[0073] Basically, in the disclosed embodiment, the oil pad manufacturing mold has two manufacturing stations, and the oil pad manufacturing mold includes an upper mold body 12 and a lower mold body 11;

[0074] At the first work station 100, the upper mold body 12 and the lower mold body 11 cooperate to form an oil outlet stamping die; at the second work station 200, the upper mold body 12 and the lower mold body 11 cooperate to form an outer contour cutting die; the upper mold body 12 has a vertical freedom of movement relative to the lower mold body 11; in the working state, the upper mold body 12 moves toward the lower mold body 11, and the oil outlet stamping die and the outer contour cutting die operate synchronously.

[0075] Specifically, taking into account the continuous processing of the oil pad and the characteristics of the punching process, the beneficial effect of the oil pad manufacturing mold implementation structure is that the masterbatch tape 300 is used as the raw material, and the upper mold body 12 and the lower mold body 11 are compositely designed. During one operation, the punching and forming process is performed twice at different positions of the masterbatch tape 300. The equipment space can be streamlined, the operation difficulty can be reduced, the processing speed can be increased, and it has good production practicality.

[0076] Specifically, several structures and components are processed on the upper mold body 12 and the lower mold body 11, respectively, and one of the specific implementation methods will be described later. Since there are several movable parts on the lower mold body 11, in order to facilitate the placement and removal of the entire oil pad manufacturing mold, a bottom plate 10 is provided below the lower mold body 11. Specifically, the bottom plate 10 can be used as a supporting component of the entire oil pad manufacturing mold, and the lower mold body 11 is fixed above the bottom plate 10; several groups of guide components 13 (only one group is shown in the figure) are provided around the top surface of the bottom plate 10, and the upper mold body 12 moves based on the guide components 13.

[0077] Further, referring to the accompanying drawings Figure 7 , in order to illustrate the corresponding relationship of the position, in the attached figure Figure 7 There are two auxiliary alignment lines as shown in FIG.

[0078] Specifically, at the first workstation 100, a stamping die 23 is provided on the lower mold body 11, and a stamping punch 21 is provided on the upper mold body 12;

[0079] The stamping die 23 has a stamping through hole adapted to the oil outlet, and a stamping blade 24 is formed at the top of the stamping die 23 at the edge of the stamping through hole; the stamping punch 21 has a stamping protrusion adapted to the oil outlet, and a stamping section 22 is formed on the side of the stamping protrusion;

[0080] The horizontal cross-sectional profile of the relatively lower punching section 22 coincides with the horizontal cross-sectional profile of the relatively upper punching section 22, or the horizontal cross-sectional profile of the relatively lower punching section 22 is located within the enclosed area of ​​the horizontal cross-sectional profile of the relatively upper punching section 22;

[0081] The profile of the punching edge 24 is the same as a horizontal cross-sectional profile of the punching section 22 .

[0082] Specifically, the stamping blade 24 and the stamping cut surface 22 cooperate to punch out a lower oil port on the mother material (a part of the contour of the punching is the lower oil port contour). In the oil pad manufacturing mold, the stamping die 23 is directly processed on the lower mold body 11, and the stamping punch 21 is arranged as an independent component. The top surface of the stamping punch 21 is pressed against the upper mold body 12. In order to ensure sufficient downward pressure, in a specific implementation, the stamping punch 21 is provided with a first connecting member 20 that passes through the upper mold body 12. The first connecting member 20 can be used to locally pressurize the stamping punch 21 from the outside to ensure that the stamping punch 21 has sufficient downward pressure for punching operations.

[0083] Furthermore, the top surface of the stamping die 23 has a first groove 25 surrounding the stamping blade 24; a first stretching transition surface 26 is formed between the first groove 25 and the stamping blade 24, and the first stretching transition surface 26 can ensure that the oil pad will not wrinkle around the oil outlet.

[0084] Further, referring to the accompanying drawings Figure 8 , at the second station 200, a cutting lower mold assembly is provided on the lower mold body 11, and a cutting upper mold assembly is provided on the upper mold body 12;

[0085] The cutting lower die assembly comprises a cutting lower die main body and a movable lower ring 30, wherein the horizontal cross-sectional shape of the cutting lower die main body is adapted to the main body, and the cutting lower die main body and the lower die main body 11 are relatively fixed in position; the movable lower ring 30 is fixed to the upper die main body 12, the inner side wall of the movable lower ring 30 is slidably fitted on the side surface of the cutting lower die main body along the vertical direction, and the outer side wall of the movable lower ring 30 is slidably fitted on the lower die main body 11, and the top surface of the lower die main body 11 forms a first cutting edge 38 at the matching position with the movable lower ring 30;

[0086] The cutting upper die assembly comprises a cutting upper die body 33 and a movable upper ring 32. The horizontal cross-sectional shape of the cutting upper die body 33 is adapted to the body. The cutting upper die body 33 is located below the upper die body 12 and can be vertically free relative to the upper die body 12. The inner side wall of the movable upper ring 32 is slidably fitted on the side of the cutting upper die body 33 in the vertical direction. The movable upper ring 32 has a curling groove 35 located on the inner side of the bottom and a second cutting blade 36 located on the outer side of the bottom.

[0087] The cutting lower die body and the cutting upper die body 33 are opposite to each other, and the moving lower ring 30 and the moving upper ring 32 are opposite to each other; the first cutting blade 38 and the second cutting blade 36 are arranged in coordination.

[0088] Specifically, the cooperation between the cutting lower mold body and the cutting upper mold body 33 is mainly used to form the planar structure of the oil pad, the cooperation between the moving lower ring 30 and the moving upper ring 32 is mainly used to form the curling protrusion structure of the oil pad, and the cooperation between the first cutting blade 38 and the second cutting blade 36 is mainly used to cut the required material from the masterbatch.

[0089] Furthermore, the cutting upper die assembly further comprises an upper pressure ring 31, the inner side wall of the upper pressure ring 31 slidingly fits on the outer side wall of the moving upper ring 32 in the vertical direction. The function of the upper pressure ring 31 is mainly to provide appropriate pressure to prevent the edge of the cut material from wrinkling. Furthermore, the top surface of the lower die body 11 has a second groove 37 surrounding the cutting edge; a second stretching transition surface is formed between the second groove 37 and the cutting edge, and the function of the second stretching transition surface can also prevent the material from wrinkling.

[0090] In actual implementation, each component that needs to move can adopt an independent driving structure for drive control and position control.

[0091] For example, the upper pressing ring 31 may be connected to the outside by a second connecting member 42 passing through the upper mold body 12 .

[0092] Specifically, in the disclosed embodiment, the upper end of the movable upper ring 32 extends outward to form an upper limit ring, the bottom surface of the upper limit ring is opposite to the top surface of the upper pressure ring 31, and the upper limit ring can limit the upper pressure ring 31. Similarly, the lower end of the movable lower ring 30 extends outward to form a lower limit ring, the top surface of the lower limit ring is opposite to the bottom surface of the lower mold body 11, and the lower mold body 11 can limit the lower limit ring. Furthermore, in order to limit the movement of the cutting upper mold body 33, the movement limitation of the cutting upper mold body 33 can be achieved by the cooperation of the fixing member 40 and the external limiting structure.

[0093] In addition, in order to improve the movement speed of the mold and realize the reset of the parts, the embodiment of the present disclosure is further provided with a first elastic member 34 and a second elastic member 39. Specifically, the two ends of the first elastic member 34 are respectively connected to the upper mold body 12 and the cutting upper mold body 33, and the two ends of the second elastic member 39 are respectively connected to the moving lower ring 30 and the bottom plate 10.

[0094] Oil pad production method:

[0095] Accordingly, the present disclosure also provides an oil pad manufacturing method, which is implemented based on the oil pad manufacturing mold and includes the following steps:

[0096] S101: preparing a master tape 300 and placing the master tape 300 between the upper mold body 12 and the lower mold body 11;

[0097] Specifically, the masterbatch tape 300 may be a metal coil or other material. The metal coil may be a metal coil as shown in the accompanying drawings. Figure 7 It illustrates the material being loaded onto the oil pad manufacturing mold; specifically, the movement of the master tape 300 is generally driven by an external device. Specifically, the driving device of the master tape 300 outside the oil pad manufacturing mold is not additionally described in the embodiment of the present disclosure.

[0098] Specifically, the masterbatch tape 300 includes working masterbatch and non-working masterbatch, and only the masterbatch tape 300 located between the upper mold body 12 and the lower mold body 11 is the working masterbatch, wherein the working masterbatch located on the first station 100 is in an unmade state, and the working masterbatch located on the second station 200 is in a first made state with an oil outlet. Specifically, since the oil pad of the embodiment of the present disclosure is made in a step-by-step continuous operation mode, the structure of the masterbatch will be changed during the production process of the oil pad, and the embodiment of the present disclosure distinguishes different structural forms of the masterbatch tape 300 according to different states.

[0099] S102: the upper mold body 12 moves toward the lower mold body 11, the oil outlet stamping die operates to punch out the oil outlet on the master batch in the unmanufactured state, the master batch on the first station 100 is converted to the primary manufacturing state, the outer contour cutting die operates to cut the oil pad on the master batch in the primary manufacturing state, and the master batch on the second station 200 is converted to the completed manufacturing state;

[0100] In one operation of the oil pad making mold, the oil pad making mold simultaneously performs two punching operations on different areas of the master tape 300. At the first station 100, the corresponding area on the master tape 300 is processed with an oil outlet; at the second station 200, the corresponding area on the master tape 300 is punched out to cut off the outer contour of the oil pad on the basis of the oil outlet, thereby obtaining the required oil pad.

[0101] The finished oil pad can be taken out by machinery or workers.

[0102] S103: driving the masterbatch belt 300 to move, the working masterbatch in the completed manufacturing state is moved out to the outside of the oil pad manufacturing mold, the working masterbatch in the primary manufacturing state is moved to the second station 200, and some non-working masterbatch is moved to the first station 100.

[0103] Through the movement of the master tape 300, waste materials are removed, the master tape processed with the oil outlet moves to the second station 200, and the non-working master tape moves to the first station 100, and the next round of oil pad mold making operation can be carried out.

[0104] With respect to the oil pad manufacturing mold structure of the embodiment of the present disclosure, further, in the second station 200, under the condition that the lower mold body 11 is provided with a cutting lower mold assembly, and the upper mold body 12 is provided with a cutting upper mold assembly, the outer contour cutting mold operation includes:

[0105] S201: driving the upper mold body 12 to move toward the lower mold body 11, and the cutting upper mold body 33 and the moving upper ring 32 move synchronously with the upper mold body 12;

[0106] Specifically, the upper mold body 12, the cutting upper mold body 33 and the moving upper ring 32 of the embodiment of the present disclosure realize synchronous movement in the following manner: Figure 8 In the structure shown, a first elastic member 34 is disposed on the back of the cutting upper mold body 33 , and the movement of the upper mold body 12 drives the movement of the cutting upper mold body 33 ; the moving upper ring 32 and the upper mold body 12 are connected as an integral structure.

[0107] It should be noted that in the schematic diagram, the cutting upper mold body 33 is flush with the bottom surface of the moving upper ring 32. In actual implementation, under the action of the first elastic member 34 and without external force, the bottom surface of the cutting upper mold body 33 is lower than the bottom surface of the moving upper ring 32.

[0108] S202: The bottom surface of the cutting upper mold body 33 presses the working masterbatch in the first contour area onto the top surface of the cutting lower mold body;

[0109] Specifically, the bottom surface of the cutting upper die body 33 presses the working master batch in the first contour area onto the top surface of the cutting lower die body, and clamps and fixes the material on the working master batch that needs to form the oil pad plane area;

[0110] S203: The upper ring 32 continues to move downward to a preset position and then retreats;

[0111] Specifically, the movement of the moving upper ring 32 is mainly to cut out a semi-finished masterbatch with an edge of the second contour from the working masterbatch through the cooperation of the first cutting blade 38 and the second cutting blade 36; specifically, in this step, under the action of the first elastic member 34, the cutting upper mold body 33 and the cutting lower mold body remain fixed, and the moving lower ring 30 is pressed down synchronously.

[0112] It should be noted that the downward movement of the moving upper ring 32 in this step needs to be designed according to the height of the curling groove 35. The reason is that the curling groove 35 on the inner side of the moving upper ring 32 also plays a role in avoiding materials in this action. It is necessary to avoid the moving position of the moving upper ring 32 being too low to prevent the inner wall of the moving upper ring 32 from damaging the material.

[0113] The retreat of the upper ring 32 needs to leave space for the folding edge to be folded later.

[0114] S204: The lower ring 30 moves upward to a preset position and then retreats;

[0115] Specifically, the movement of the lower ring 30 is mainly to drive the semi-finished masterbatch between the first contour and the second contour to be folded upward, so that the semi-finished masterbatch between the first contour and the second contour forms a folded edge.

[0116] S205: The upper ring 32 moves downward to a preset position, and the curling groove 35 processes the folded edge into a curling protrusion.

[0117] Specifically, the function of the moving upper ring 32 in this step is to curl the folded edge into a curled edge protrusion.

[0118] Further, under the condition that the cutting upper die assembly further includes an upper pressure ring 31, the outer contour cutting die operation includes: before the first cutting blade 38 and the second cutting blade 36 cooperate to cut a semi-finished masterbatch with an edge of the second contour from the working masterbatch, the upper pressure ring 31 is pressed on the working masterbatch with a preset pressure. Specifically, the action of the upper pressure ring 31 is independently controlled by an external device through a connecting piece 42. The upper pressure ring 31 plays a role in pre-fixing the masterbatch on the one hand, and in preventing the masterbatch from deforming and wrinkling on the other hand.

[0119] In summary, the present disclosure provides an oil pad, an oil pad manufacturing mold and an oil pad manufacturing method. The oil pad is provided with an oil outlet to facilitate the discharge of waste oil. The oil pad is made of thin material, which can make the oil pad slightly deformed under the weight of food, so that the waste oil can be quickly and automatically discharged from the oil outlet; the protrusions on the periphery of the oil pad can prevent the waste oil from overflowing; the oil pad manufacturing mold and the oil pad manufacturing method can simultaneously perform two punching process steps, and the processing efficiency is relatively high; at the second workstation 200, the oil pad manufacturing mold can integrate the two processes of cutting the edge contour of the oil pad and curling the edge of the oil pad into one operation process, further improving the processing efficiency of the oil pad, and having good practicality.
