Description

Technical Field

[0001] This application relates to the field of food production equipment technology, specifically to a pneumatic type glutinous rice ball patching machine. Background Technology

[0002] To enhance the appearance of glutinous rice balls and other pastries, making them both visually appealing and nutritious, and thus stimulating consumer desire, the traditional food industry typically alters the overall color of glutinous rice balls by adding fruit and vegetable powders or food colorings to the dough. To further enrich the variety and aesthetics of the food's shape, three-dimensional decorations can be applied to glutinous rice balls, such as attaching decorative dough pieces with specific outlines to the surface, thereby achieving a three-dimensional shape.

[0003] However, traditional decoration of glutinous rice ball dough is often done manually by workers, resulting in low application efficiency and inconsistent placement, leading to poor product consistency and difficulty in adapting to large-scale industrial production. To address this, a patent document with publication number CN117751956A, known to the inventors, discloses a dough-cutting and decorating device that automatically cuts decorative pieces from the dough and presses them onto the glutinous rice balls. When the dough is conveyed to the cutting surface and the tray containing the glutinous rice balls is conveyed below the mold base, the conveying of the dough and tray stops, with the glutinous rice balls in the tray positioned directly below the material feeding channel. At this time, the lower end of the push rod is located in the cutter, and the dough-cutting drive mechanism drives the dough-cutting and decorating assembly downwards. Through the cooperation of the first and second cutting blades, the desired decorative piece is cut from the dough. The decorating drive mechanism then drives the push rod to extend from the lower end of the cutter, pressing the decorative piece onto the top of the glutinous rice ball, thereby improving product consistency and production efficiency.

[0004] However, during the implementation of the technical solutions in this application, the inventors discovered that the decorative pieces could stick to the cutting tool during the decal application, making it difficult to reliably attach them to the surface of the glutinous rice ball. The aforementioned decal application device uses a push rod inside the cutting tool. When the decorative piece is applied to the surface of the glutinous rice ball, the decal application driving mechanism drives the push rod to extend, causing the decorative piece to detach from the cutting tool and press it onto the top of the glutinous rice ball. However, this solution has a complex cutting tool structure, requiring an embedded push rod with a separate control mechanism. Furthermore, the small contact area between the push rod and the decorative piece results in concentrated stress, leading to a high breakage rate and affecting product quality. In addition, in actual production, the inventors found that not all decorative pieces adhere to the cutting tool. Since the decorative pieces, after stamping, need to be applied to the surface of the glutinous rice ball under further pressure from the cutting tool, those not adhered to the cutting tool will detach under their own weight and fall freely, making their application position uncontrollable and affecting the final product quality.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In view of at least one of the above technical problems, this disclosure provides a pneumatic type glutinous rice ball patching machine, which aims to solve the technical problems of complex structure and low quality of final product in existing technical solutions.

[0007] According to one aspect of this disclosure, a pneumatic type glutinous rice ball patching machine is provided, comprising a frame, a plurality of fixed blades arrayed and fixed to the base plate of the frame and having corresponding contoured blade holes, a pressing cylinder fixed at the center of the top of the frame, a driven plate fixed to the actuating end of the pressing cylinder and parallel to the base plate of the frame, and a plurality of movable blades arrayed at the bottom of the driven plate and whose array positions correspond one-to-one with the blade holes on the fixed blades; the outer contour of the movable blades matches the contour of the blade holes on the fixed blades, the driven plate has a plurality of air chambers corresponding one-to-one with each of the movable blades, and each movable blade has an air hole at its end for contacting the decorative piece that communicates with the air chambers, the air chambers being connected to an external air source through air inlets to provide the negative or positive pressure required by the air chambers as needed.

[0008] In some embodiments of this disclosure, the pneumatic glutinous rice ball patching machine further includes a fixed frame plate that is parallel to the base plate of the frame and fixed at the middle position of the frame; a plurality of guide posts are fixedly provided on the top surface of the driven plate, and guide seats for sliding and nesting to the outside of the corresponding guide posts are fixedly provided on both sides of the frame plate.

[0009] In some embodiments of this disclosure, an action frame plate parallel to the fixed frame plate is fixedly provided on the top of each guide post; a position feedback element is fixedly provided on one side of the action frame plate, and a position detection element for detecting the position of the position feedback element is fixedly provided on the side plate of the frame.

[0010] In some embodiments of this disclosure, the position detection element includes two proximity sensors arranged vertically and communicatively connected to a controller; the controller is also used to control the start and stop of the pressing cylinder.

[0011] In some embodiments of this disclosure, the pneumatic glutinous rice ball patching machine further includes a baffle assembly for placing the dough strip to adhere to the moving cutter head.

[0012] In some embodiments of this disclosure, the baffle assembly includes a baffle plate disposed below the driven plate and having an array of a plurality of moving blade holes corresponding one-to-one with each moving blade head, an actuating rod fixed to the top surface of the baffle plate and correspondingly passing through the edge of the driven plate, a limiting head disposed at the top of the actuating rod, and a spring sleeved outside the actuating rod and located between the limiting head and the driven plate.

[0013] In some embodiments of this disclosure, the driven plate has a plurality of air grooves on one side corresponding to the moving cutter head, which match the outline of each moving cutter head. The corresponding end of each moving cutter head is provided with a fixing plate for fixing to the corresponding air groove and correspondingly closing the air groove to form the air cavity.

[0014] In some embodiments of this disclosure, the top of the driven plate is fixedly provided with an air passage plate for connecting each of the air chambers.

[0015] In some embodiments of this disclosure, the driven plate has an air passage hole at the top corresponding to each of the air chamber positions, which communicates with the air chamber, and the end face of the air passage plate that is used to fit and contact the driven plate has an annular air passage for connecting each of the air passage holes.

[0016] One or more technical solutions provided in this application embodiment have at least the following technical effects or advantages: By setting air chambers corresponding to each moving blade head and opening air holes at the end face of each moving blade head that communicate with the corresponding air chambers, negative pressure is supplied to each air chamber after the decorative sheet is stamped and before it comes into contact with the food to be decorated under the push of the moving blade head to form a negative pressure environment. This enables the moving blade head to adsorb the decorative sheet, avoiding the problem that the decorative sheet will detach from the moving blade head due to its own gravity and fall freely, resulting in inaccurate final attachment position. In addition, after the decorative sheet comes into contact with the food to be decorated, positive pressure is supplied to each air chamber to form a positive pressure environment, thereby enabling the expulsion of pressurized gas at the moving blade head, which helps the decorative sheet separate from the moving blade head and prevents adhesion problems.

Therefore, they should not be construed as limitations on this application.

[0022] The programs involved or relied upon in the following embodiments are all conventional or simple programs in this technical field, and those skilled in the art can make conventional selections or adaptive adjustments according to specific application scenarios. Unless otherwise specified, the devices involved in the following embodiments are all conventional commercially available products.

[0023] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This example discloses a pneumatic type glutinous rice ball patching machine. See [link to relevant documentation]. Figure 1 The schematic diagram shown is a partial structural diagram of a dough pasting machine. It includes a frame 1, through which a pasting machine is fixedly connected to a dough conveyor belt, thereby achieving the stamping and pasting process of the dough at the conveyor belt. Specifically, in this embodiment, the frame 1 includes parallel side plates 11 and a top plate 12 and a bottom plate 13 respectively connected to the top and bottom sides of the side plates. Furthermore, for protection purposes, protective plates are provided on the front and rear sides of the frame. Figure 1 (Not shown in the image).

[0025] See Figure 1A plurality of fixed blade plates 2 are fixedly arranged in an array at the base plate 13 of the frame 1. Each fixed blade plate 2 has a blade hole that matches the contour of the decorative sheet to be cut, and the base plate has through holes corresponding to each blade hole for the decorative sheet to pass through. In addition, in this example, a movable blade head 3 is provided to match the fixed blade plates 2. The outer contour of the movable blade head 3 matches the contour of the blade hole at the fixed blade plate 2. Thus, through the one-to-one matching between each movable blade head 3 and each blade hole, the sheet material between the fixed blade plates 2 and the movable blade head 3 is cut and shaped. For control of the movement of each movable blade head 3, see [link to documentation]. Figure 1 In this embodiment, a pressing cylinder 4 is fixedly installed at the top plate 12 of the frame 1, and a driven plate 5 is fixedly connected to the actuating end of the pressing cylinder 4. The driven plate 5 is arranged parallel to the bottom plate 13. Each moving cutter head 3 is arranged in an array on the bottom surface of the driven plate 5. Under the extension and retraction drive of the pressing cylinder 4, the driven plate 5 moves up and down in a direction perpendicular to the bottom plate 13, thereby driving each moving cutter head 3 to cooperate with the cutter holes at each fixed cutter plate 2 to perform a stamping operation or a moving cutter head reset operation on the surface belt. In order to ensure that each moving cutter head 3 can correspond one-to-one with the cutter holes at the fixed cutter plate 2, the array position of the moving cutter head 3 on the driven plate 5 is the same as the array position of the cutter holes and corresponds one-to-one. In addition, in order to ensure that the force on the driven plate 5 is relatively balanced and improve the stability of equipment operation, in this example, the pressing cylinder 4 is fixedly installed at the center position of the top plate 12, and the moving end of the pressing cylinder 4 is connected to the center position of the driven plate 5.

[0026] To ensure the smooth movement of the driven plate 5 with the pressing cylinder 4, in this embodiment, see... Figure 1 A fixed frame plate 61 is fixedly installed parallel to the base plate 13 at the middle position of the frame. To avoid positional interference between the fixed frame plate 61 and the actuating shaft of the pressing cylinder 4, a window is opened in the middle of the fixed frame plate 61 in this example, and the whole is a frame structure. In addition, a number of guide posts 62 are fixedly installed on the top surface of the driven plate 5, and a number of guide seats 63 matching the guide posts are fixedly installed on both sides of the top of the fixed frame plate 61. The guide seats 63 have guide holes with a diameter matching the outer diameter of the guide posts along their axis. By sliding and nesting each guide post into the guide hole of the corresponding guide seat, the movement of the guide post 62 is limited by the guide seat 63 which is fixed relative to the frame. Since each guide post 62 is fixedly connected to the driven plate 5, the movement stability of the driven plate 5 is ensured.

[0027] See Figure 1In this embodiment, each guide post 62 is also fixedly provided with an action frame plate 64 parallel to the base plate 13 at its top. On the one hand, the action frame plate 64 can limit the position of each guide post 62, which helps to ensure the verticality and movement stability of each guide post 62. On the other hand, in this example, the movement position of the moving head is detected based on the action frame plate 64. Specifically, in this embodiment, since the moving head 3 and the guide post 62 are relatively fixed on both sides of the driven plate 5, and the action frame plate 64 is fixed on the top of each guide post 62, the action frame plate 64 and each moving head 3 are in a relatively fixed relationship. Therefore, the movement distance of the moving head 3 is the same as the movement distance of the action frame plate 64. See also... Figure 1 A position feedback element 71 is fixedly installed at one edge of the action frame plate 64, and two position detection elements 72 for detecting the position feedback element 71 are arranged vertically on the side plate 11 of the frame. In this example, the position feedback element 71 is specifically an L-shaped plate, and the two position detection elements 72 are proximity sensors. The positions of the two position detection elements 72 correspond to the positions where the moving head 3 performs the pressing and attaching operation and the reset position of the moving head 3, respectively. In addition, in this embodiment, the glutinous rice ball patch machine also includes a controller. The two proximity sensors are electrically connected to the controller, so that when the position detection element 72 detects the position feedback element 71, the controller stops the pressing cylinder operation under the current operation, thereby realizing position feedback and operation control.

[0028] Furthermore, in this embodiment, to ensure that the decorative sheet after pressure cutting can be accurately attached to the surface of the glutinous rice ball to be decorated, see [reference needed]. Figure 2 The driven plate 5 has air chambers corresponding to each moving cutter head 3. Specifically, in this example, the driven plate 5 has a plurality of air grooves 51 arranged in an array on the end face corresponding to the moving cutter head. The array position of the air grooves 51 is the same as and corresponds one-to-one with the array position of each moving cutter head 3 on the driven plate. See [link to relevant documentation]. Figure 1 On the other side of the driven plate 5, there are air ports 52 that communicate with each air groove 51. See also... Figure 2To achieve the connection between each moving cutter head 3 and the driven plate 5, in this example, a fixing plate 31 is fixedly provided at the corresponding end of each moving cutter head 3. Thus, on the one hand, a reliable sealed connection between the moving cutter head 3 and the driven plate 5 is achieved through the fixing plate; on the other hand, the fixing plate and the moving cutter head 3 seal the air grooves 51 at the driven plate 5, thereby sealing the forming air cavity. Furthermore, in this embodiment, each moving cutter head 3 has an air hole 32 at the end that contacts the decorative piece, which communicates with the air cavity, and each air hole 32 is connected to its corresponding air cavity. Therefore, when the glutinous rice ball patching machine is working, the air ports of the air chambers corresponding to each moving cutter head 3 are connected to an external air pressure source through hoses. The air pressure source can provide positive or negative pressure as needed. Thus, as the moving cutter head 3 cooperates with the fixed cutter plate 2 to press and form the decorative piece and then moves further downward with the moving cutter head 3, pressing the decorative piece down to the top of the glutinous rice ball to be decorated below the glutinous rice ball patching machine, the external air pressure source provides negative pressure, thereby creating a negative pressure environment in each air chamber. The negative pressure adsorption of the decorative piece is achieved through the air holes 32 at each moving cutter head 3, avoiding the problem of the decorative piece after being cut and formed detaching from the moving cutter head 3 under its own weight and falling freely, resulting in inaccurate attachment position. Furthermore, during the attachment process, once the moving blade head reaches its designated position and the decorative piece contacts the glutinous rice ball, an external pressure source is adjusted to deliver positive pressure air into the air chamber. This pressure air is then blown out from the air holes 32 at each moving blade head 3, separating the decorative piece from the moving blade head 3. This avoids the problem of the decorative piece sticking to the moving blade head, which would then detach from the attachment position as the moving blade head resets. This ensures the reliability of the attachment process and the accuracy and consistency of the attachment position. In addition, in this embodiment, since the moving blade head is not a simple graphic, the air holes at each moving blade head 3 are non-uniform to minimize adhesion problems. To provide effective pressure air supply to each air hole, the contour of each air groove 51 matches the contour of each moving blade head 3, facilitating the flexible distribution of the air holes 32 and ensuring reliable air supply to all air holes on the moving blade head.

[0029] In this embodiment, each moving cutter head 3 needs to have an air port 52 for air intake, which leads to a complex structure and air supply pipeline. Therefore, in other embodiments, see Figure 3 The driven plate 5 is also fixedly provided with an air passage plate 53 for connecting each air chamber. In this specific example, the air passage plate 53 is an annular plate that covers the air passage hole 54 for air inlet of each air chamber. The end face of the air passage plate 53 that is in contact with and fits the driven plate 5 is provided with an annular air passage 55. Thus, by connecting each air chamber through the annular air passage 55, it is only necessary to control the air inlet and outlet of the annular air passage 55 to achieve the overall control of the pressure gas in each air chamber, thus avoiding complex structure and pipeline layout.

[0030] Furthermore, in this embodiment, to avoid the problem of the dough tape sticking to the moving cutter head during retraction and reset, causing the dough tape to be lifted by the passive cutter head, see [reference needed]. Figure 1 The glutinous rice ball mounting machine also includes a baffle assembly. Specifically, the baffle assembly includes a baffle plate 81 located below the driven plate 5. The baffle plate 81 has an array of moving blade holes that match each moving blade head and are used to pass through each moving blade head, thereby avoiding positional interference between the baffle plate 81 and the moving blade heads. Additionally, an actuating rod 82 is fixed perpendicularly to the baffle plate at the top surface of the baffle plate 81. (See [link]). Figure 1 A through hole is provided at the edge of the driven plate 5, and each actuating rod 82 passes through the through hole at the edge of the driven plate, so that the baffle plate 81 can move vertically relative to the driven plate 5. Furthermore, each actuating rod 82 has a limiting head at its top, and a spring 83 is sleeved on the actuating rod 82 between the limiting head and the driven plate 5. Thus, when the moving cutter head presses down to stamp the decorative leather, the baffle plate 81 moves downward with the driven plate 5. When the moving cutter head moves upward to perform a reset operation, when the baffle plate 81 rises with the driven plate 5 until the actuating rod 82 abuts against the fixed frame plate 61, the baffle plate stops moving. The driven plate then rises further with the pressure-cutting cylinder, correspondingly compressing the spring. During the further rise of the moving cutter head with the driven plate 5, the adhesive strip at its end contacts the no longer moving baffle plate 81, thereby separating the strip from the moving cutter head.

[0031] Although some preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
