Description

Technical Field

[0001] This application relates to the field of food production equipment, specifically to a decorative dough stamping device. Background Technology

[0002] Noodles are common foods in daily life, such as glutinous rice balls, steamed buns, and bread. With the advancement of production technology and the improvement of people's living standards, the requirements for noodles are not only about taste, but also about nutrition and aesthetic appearance. Early noodle decoration relied mainly on hand-shaping and carving with knives. However, with the development of food science, the application of natural pigments (such as vegetable juice and fruit powder) and safe synthetic pigments has enriched the color expression of noodle decoration. Dough dyed with pigments is made into various shapes of dough sheets, which are then attached to the noodles to create different shapes such as persimmons. This not only increases the texture of the noodles, but also ensures nutritional balance, and makes the shapes more unique and beautiful.

[0003] Traditional dough sheet forming is mostly done manually, where workers hold molds and press them one by one onto a dough strip to obtain decorative dough sheets. This method is inefficient and cannot meet the needs of industrial production. The inventors are aware of a food packaging and decorating device disclosed in CN221807784U, whose decorating mechanism includes a conveyor assembly and a decorating assembly installed between the conveyor assembly. During the dough sheet cutting operation, an input conveyor belt drives the dough strip into the decorating assembly, and then an output conveyor belt rotates synchronously, driving the remaining dough strip in the decorating assembly out.

[0004] However, the inventors discovered during the process of implementing the technical solution of this application that the above-mentioned decorative skin forming process requires the power of the skin belt to pass through the skin-applying assembly under the drive of two conveyor belts. The skin belt within the range of the skin-applying assembly is separated from the transmission belt and only has friction with the punching fixed knife of the skin-applying assembly. When the skin is thick, it can form the decorative skin with the corresponding contour well. However, for the skin belt with relatively thin thickness or relatively low toughness, when it is pulled and passes through the punching fixed knife, the friction between the skin belt and the surface of the punching fixed knife is very likely to cause the skin belt to break and the pattern to deform, affecting the subsequent stamping and cutting operation.

[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 decorative faceplate stamping device, which mainly solves the problem that existing decorative faceplate stamping operations are prone to causing faceplate breakage or severe deformation of the pattern, thus interrupting the stamping operation.

[0007] According to one aspect of this disclosure, a decorative fabric stamping apparatus is provided, comprising a fabric conveyor mechanism and a stamping mechanism fixed relative to the frames on both sides of the fabric conveyor mechanism; the fabric conveyor mechanism includes a conveyor belt with a plurality of punches arranged in an evenly spaced array, and a roller for driving the conveyor belt to rotate cyclically and dividing the conveyor belt into a carrying section and a return section; the punches on both sides of the roller at the conveyor belt are projected one-to-one with the projections of the conveyor belt carrying section in the plane; a plurality of positioning pins are arranged in a circular array on both ends of the roller, and a plurality of positioning holes for passing through the positioning pins are correspondingly opened on both sides of the conveyor belt; the stamping mechanism includes a fixed blade plate with a plurality of cutting holes, and a plurality of moving blades matching the contour of the cutting holes on the fixed blade plate; the distribution of the cutting holes on the fixed blade plate matches the distribution of the punches on the conveyor belt, and the fixed blade plate is located below the carrying section of the conveyor belt and is in corresponding contact with the carrying section.

[0008] In some embodiments of this disclosure, the outline range of each punch at the conveyor belt is larger than the outline range of the cutter hole at the fixed cutter plate.

[0009] In some embodiments of this disclosure, the outline of each punch at the conveyor belt is a rectangle that completely covers the outline of the cutter hole at the fixed cutter plate.

[0010] In some embodiments of this disclosure, the diameter of the positioning hole is larger than the diameter of the positioning pin; and the height by which the positioning pin protrudes from the roller is not less than the thickness of the conveyor belt.

[0011] In some embodiments of this disclosure, the conveyor belt mechanism is further provided with a slag receiving box located between the conveyor belt carrying section and the return section at the frame downstream of the stamping mechanism; a slag scraper is fixedly provided on the side of the slag receiving box away from the stamping mechanism and is correspondingly attached to the lower surface of the conveyor belt carrying section.

[0012] In some embodiments of this disclosure, the slag receiving box includes a slag pushing plate serving as the outer wall of the slag receiving box, and a push rod fixedly connected to the slag pushing plate and having a length greater than the length of the slag receiving box.

[0013] In some embodiments of this disclosure, the tail end of the noodle conveyor is further provided with a pressing roller for pressing the noodle belt to move along the conveyor belt, and a guiding roller for guiding the residual noodle belt after stamping and moving synchronously with the roller.

[0014] In some embodiments of this disclosure, the stamping mechanism further includes a drive unit for driving each of the moving cutter heads to move in a direction perpendicular to the fixed cutter plate.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: the conveyor belt with several perforations in an array is used to transport the face belt, thereby avoiding the influence of the conveyor belt on the stamping operation of the stamping mechanism based on the perforations, so that the face belt does not detach from the conveyor belt during stamping and is supported by the conveyor belt throughout the process. Compared with the traditional face belt being transported and stamped between multiple mechanisms, the risk of face belt breakage is effectively avoided, the downtime frequency is greatly reduced, and the number of device parts is greatly reduced compared with the traditional decorative face sheet stamping device. While simplifying the device structure and reducing costs, the stamping effect and continuity are greatly improved. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. 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] Existing decorative sheet forming devices, when stamping relatively thin or low-toughness sheet materials, face the risk of breakage due to friction between the sheet material and the stamping cutter at the stamping station. This leads to stamping failure, interruption of sheet material transport, and machine shutdown, which severely impacts stamping efficiency. Therefore, this example discloses a decorative sheet stamping device, see [link to relevant documentation]. Figure 1 It includes a dough conveying mechanism 1 and a stamping mechanism 2; wherein, the dough conveying mechanism 1 is used for conveying dough, and the stamping mechanism 2 is used for stamping decorative dough at the conveyed dough.

[0025] Specifically, in this embodiment, see Figure 1 The dough conveyor mechanism 1 includes a frame 11 arranged parallel to both sides. Rollers are mounted on the front and rear ends of the frame 11 via bearings, and a conveyor belt 12 is fitted over the rollers. In this example, the rollers include a driven roller on the feed side of the dough conveyor mechanism 1 and a driven roller 13 on the discharge side. The driven roller 13 is driven by a roller motor 131, thereby causing the conveyor belt 12, which is fitted between the driven roller 13 and the driven roller, to rotate cyclically. The dough enters the dough conveyor mechanism 1 from the driven roller side and moves synchronously with the rotation of the conveyor belt 12. It is then stamped into decorative dough at the stamping mechanism 2. After passing through the stamping mechanism, the dough forms a residual dough strip, which continues to move with the conveyor belt 12 and is output from the discharge side of the driven roller 13 side of the dough conveyor mechanism 1 for subsequent recycling.

[0026] In order to ensure that the face belt moves smoothly and synchronously with the conveyor belt 12, see the following in this embodiment. Figure 1A pressing roller 14 is provided at the tail end of the noodle conveyor 1, i.e. the discharge side, so that the noodle belt is pressed and brought into contact with the conveyor belt 12. In addition, the residual noodle belt is output from the discharge side of the noodle conveyor. Since the noodle belt is relatively soft, in order to prevent it from drooping at the discharge end of the noodle conveyor and getting caught in the conveyor belt, a guide roller 15 is provided in this embodiment. The guide roller 15 guides the residual noodle belt so that it is relatively away from the discharge end of the noodle conveyor. In this embodiment, considering that the residual dough belt loses its traction force when it moves to the guide roller 15, and to avoid the problem of the residual dough belt continuously being conveyed to the guide roller 12 by the conveyor belt 12 due to the residual dough belt being stationary or moving slowly at the guide roller 15, thus causing the dough belt to accumulate at the discharge end of the dough belt conveyor mechanism, the guide roller 15 is connected to the drive roller 13 in this embodiment. The roller shaft of the guide roller 15 and the cylinder shaft of the drive roller 13 are respectively fixedly provided with pulleys at their ends, and the two pulleys are fitted with drive belts. Thus, the rotation of the guide roller 15 can be realized by the roller motor 131, reducing the cost and size of the device. At the same time, the guide roller 15, which has power and rotates synchronously with the drive roller and the conveyor belt, realizes the traction of the dough belt and avoids the accumulation of dough belt at the discharge port of the dough belt conveyor mechanism.

[0027] To further address the problem of easy breakage of the surface belt at the punching station caused by the two-stage conveyor belt traction method used in traditional decorative surface forming (i.e., conveyor belts on both sides of the punching station for surface belt drive), in this embodiment, the conveyor belt 12 of the surface belt conveyor mechanism 1 is a single, continuous belt. Unlike traditional conveyor belts, in this embodiment, the conveyor belt 12 has several equally spaced perforations 121. For ease of description, the two rollers divide the conveyor belt 12 into an upper carrying section for contacting and conveying the surface belt, and a lower return section opposite to the carrying section. Furthermore, in this example, the punches 121 at the conveyor belt 12 are distributed in columns parallel to the conveying direction of the conveyor belt 12 and rows perpendicular to the conveying direction of the conveyor belt 12. By controlling the row spacing to match the diameter of the roller, the projections of the punches 121 on the plane of the conveyor belt carrying section and the return section of the conveyor belt 12 can be aligned one by one. This allows the decorative surface formed by the stamping mechanism to fall through the corresponding upper and lower punches 121 and be attached to the decorative surface point below the surface conveying mechanism 1.

[0028] Specifically, the dough belt moves synchronously with the conveyor belt 12. To ensure that the decorative fabric is stamped without detaching from the conveyor belt 12, in this embodiment, the stamping mechanism 2 is fitted and connected to the dough belt conveyor mechanism 1. See [link to documentation]. Figure 2In this example, the stamping mechanism 2 includes a housing 21, which is fixed to the frame on both sides of the conveyor belt 1 via connecting plates 22 on both sides. Additionally, the stamping mechanism includes several fixed blade plates 23 fixed to the bottom plate of the housing 21 (the area of ​​the bottom plate corresponding to the fixed blade plates 23 is a hollow area). Each fixed blade plate 23 has several axially oriented holes that match the contour of the decorative surface to be stamped. Corresponding to the fixed blade plates 23, the stamping mechanism 2 also includes moving blades 24, the number of which matches the number of axially oriented holes. The outer contour of each moving blade matches the inner contour of each axially oriented hole. The moving blades 24 are arrayed on a blade plate 25, which is driven by a drive unit consisting of a stamping motor 26. Thus, under the drive of the stamping motor 26, each moving blade 24 moves synchronously along a direction perpendicular to the fixed blade plates 23, stamping the surface between the fixed blade plates 23 and the moving blades 24 to form the decorative surface.

[0029] In this embodiment, to achieve the cooperation between the stamping mechanism 2 and the conveyor belt 1, the carrying section of the conveyor belt 12 is positioned between the fixed blade plate 23 and the moving blade head 24 of the stamping mechanism, ensuring that the fixed blade plate 23 and the carrying section of the conveyor belt 12 are in corresponding contact. Furthermore, in this embodiment, the distribution of the punch holes at the fixed blade plate 23 matches the distribution of the punch holes at the conveyor belt 12, thereby ensuring that after each step of the conveyor belt 1, the punch holes at the conveyor belt 12 correspond one-to-one with the punch holes at the fixed blade plate 23. In addition, the outline range of each punch hole 121 at the conveyor belt 12 is set larger than the outline range of each punch hole at the fixed blade plate 23, ensuring that the outline of the punch hole can be completely covered by the outline of the punch hole. This allows the stamped decorative surface to pass through the conveyor belt 12 for subsequent application to the surface. Specifically, in this example, the outline of each punch hole 121 at the conveyor belt 12 is set to be a rectangle that completely covers the outline of the punch holes at the fixed blade plate 23.

[0030] Thus, the dough strip enters the stamping range of the stamping mechanism along with the conveyor belt 12. During the stamping operation, since the outer shell of the stamping mechanism is relatively fixed to the two side frames of the dough strip conveyor mechanism, the fixed blade plate 23, located below the conveyor belt 12 and fixed to the bottom plate of the stamping mechanism outer shell, can effectively support the carrying section of the conveyor belt. The corresponding punches on the conveyor belt 12 prevent the conveyor belt from being within the cutting range of the moving blade head 24. The moving blade head 24 then stamps within the dough strip area corresponding to each punch. The stamped decorative dough is extruded from the punches of the fixed blade plate 23 and falls through the return section punches of the conveyor belt 12, completing the stamping of the decorative dough. Furthermore, in actual use, the decorative dough stamping device is used in conjunction with the pastry conveyor belt 3, see [link to relevant documentation]. Figure 3The pastry conveyor belt 3 is used to transport pastries to be decorated, and the decorative dough stamping device is installed above the pastry conveyor belt 3. By arranging the pastries on the pastry conveyor belt 3, the decorative dough formed by the stamping device is pressed down from the return section of the conveyor belt by the moving cutter head 24 and then pressed onto the top of each pastry to be decorated on the pastry conveyor belt 3 by the power of the moving cutter head 24.

[0031] See Figure 1 In this embodiment, considering that the rotation of the conveyor belt 12 relies on the friction between the conveyor belt 12 and the roller, and that there is a risk of slippage between the conveyor belt 12 and the roller, the step distance of the conveyor belt 12 as the roller rotates changes. This leads to the inability of the punches on the conveyor belt 12 to align vertically, and the inability of the cutter holes on the fixed cutter plate 23 and the moving cutter head 24 to align with the punches on the conveyor belt 12, resulting in stamping failure. Therefore, in this example, several positioning pins 4 are arranged in a circular array at equal intervals on both ends of the roller, and several positioning holes 5 are correspondingly opened on both sides of the conveyor belt 12. The diameter of the positioning holes 5 is larger than the diameter of the positioning pins 4, so that the positioning pins 4 on the roller can smoothly enter or exit the positioning holes 5 as the conveyor belt 12 moves. Furthermore, in this example, the height of the positioning pins 4 protruding from the roller is set to be no less than the thickness of the conveyor belt 12, thereby ensuring that the positioning pins 4 located in the positioning holes 5 can effectively limit the movement of the conveyor belt 12. Therefore, the accuracy of the step distance of the conveyor belt 12 is ensured by the cooperation between the positioning pin 4 and the positioning hole 5.

[0032] Furthermore, the inventors discovered during the implementation of the technical solution of this application that residues are formed at the punched holes 121 of the conveyor belt 12 after the dough is stamped. These residues adhere to locations such as rollers as the conveyor belt 12 moves, affecting the accurate and reliable movement of the conveyor belt 12 and making it difficult to clean. Therefore, in this embodiment, a slag removal unit is fixedly installed below the bearing section of the conveyor belt 12. See details below. Figure 4 The slag removal unit includes a slag scraper 61 and a slag collection box 62. The slag scraper 61 is fixed to the frames on both sides of the conveyor belt 1 and is oriented in the opposite direction to the movement of the conveyor belt 12. The corresponding end of the slag scraper 61 contacts the bottom of the bearing section of the conveyor belt 12, thus achieving the slag scraping effect. A slag collection box 62 is provided to prevent surface slag from falling randomly and being difficult to collect and clean. Specifically, the slag collection box 62 is also fixed to the frames on both sides of the conveyor belt 1 and is positioned below the end of the slag scraper 61 that contacts the conveyor belt 12. The slag collection box 62 has a limited capacity; to achieve a cleaning effect, see [reference needed]. Figure 4In this example, one outer wall of the slag receiving box 62 is movably set and serves as a slag pushing plate 621. A push rod 622 is fixedly provided on one side of the slag pushing plate 621. The length of the push rod 622 is greater than the length of the slag receiving box 62. Thus, during the slag receiving process, the slag pushing plate 621 is in contact with the other outer wall. When the slag in the slag receiving box 62 accumulates and needs to be cleaned, the push rod 622 is pushed to push the slag in the slag receiving box 62 out, making it easy to collect and clean.
