Description

Technical Field

[0001] This application relates to the field of food processing, and in particular to a pie crust covering device. Background Technology

[0002] As a traditional and beloved food, pies have a huge market demand, and with the improvement of living standards, people's requirements for pies are also getting higher and higher. Pie crust making equipment can not only meet people's demand, but also ensure that the pie crust is of uniform thickness, ensuring the appearance and taste of the finished pie.

[0003] The common way to cover pies is by hand. Workers usually roll out the dough by hand and cover the pie with the prepared pie dough. This method not only requires a lot of manpower, but also has low efficiency and is difficult to achieve large-scale production. While some simple semi-automated equipment can improve the efficiency, the thickness of the dough produced cannot be adjusted as needed, and it cannot meet the needs of covering pies of different thicknesses. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a pie crust covering device that can automatically cut crust covering rods while adjusting the distance between the guide tube and the conveyor belt to ensure that the distance from the outlet end of the guide tube to the top of the pie is at a set value, thus adapting to the crust covering requirements of pies of different thicknesses.

[0005] This application is achieved through the following technical solution: A pie crust covering device includes a frame with a vertical slide rail on its side wall. A movable frame is slidably connected to the vertical slide rail. The upper end of the movable frame has several vertically arranged guide tubes for holding crust covering rods. The outlet end of each guide tube extends into the middle of the movable frame, and an opening groove is provided on the side wall of the guide tube near the outlet end. A conveying mechanism is provided at the opening groove to abut against the crust covering rods. The conveying mechanism moves the crust covering rods in the guide tubes downwards at a set speed. A shearing mechanism is provided on the movable frame to cut the crust covering rods output from the outlet end of the guide tubes. A conveyor belt is provided below the shearing mechanism to convey pies. A height adjustment device is connected to the lower end of the movable frame to adjust the distance between the outlet end of the guide tubes and the conveyor belt to ensure that the distance from the outlet end of the guide tubes to the top of the pie is at a set value.

[0006] By adopting the above technical solution, a guide tube is arranged at the upper end of the movable frame. An opening groove is provided on the side wall of the guide tube near the outlet end. A conveying mechanism is set at the opening groove to abut against the cover stick. This ensures that the conveying mechanism can control the cover stick to move to the outlet end of the guide tube at a set speed through the opening groove. At the same time, in conjunction with the shearing mechanism, it can ensure that the thickness of the pie cover is the same after cutting. The cutting thickness of the cover can be adjusted by adjusting different conveying speeds. Several vertically arranged guide tubes are provided at the upper end of the movable frame, which can improve the efficiency of the cover stick transportation. In conjunction with the shearing mechanism, multiple cover sticks can be cut, improving production efficiency. The conveyor belt set below the shearing mechanism can automatically transport the pie to the underside of the shearing mechanism for easy covering. The guide tube, shearing mechanism, and conveying mechanism are all located on the movable frame, which can ensure that after the height adjustment device adjusts the movable frame to the desired height, the conveying mechanism and shearing mechanism can still work with the guide tube to complete the cutting of the cover stick, so as to meet the needs of pie cover of different thicknesses.

[0007] Optionally, the height adjustment device includes a first electric telescopic rod; the free end of the first electric telescopic rod is connected to the lower end of the movable frame.

[0008] By adopting the above technical solution, the connection between the free end of the first electric telescopic rod and the lower end of the movable frame ensures that the first electric telescopic rod can provide power for the height adjustment of the movable frame. In addition, the electric telescopic rod has the characteristics of high automation and high control precision, which is conducive to improving the accuracy of the cover. Furthermore, the stable power output of the electric telescopic rod can ensure that there will be no obvious jamming during the adjustment of the height of the movable frame.

[0009] Optionally, the opening slots are symmetrically arranged on the guide tube; the conveying mechanism includes a rotating shaft rotatably connected to the middle of the movable frame, the rotating shaft is powered by a motor to rotate, and a plurality of rotating wheels are evenly distributed on the rotating shaft, the rims of the rotating wheels are placed in the opening slots and abut against the cover bar.

[0010] By adopting the above technical solution, the rotating shaft is powered by a motor to rotate, which can ensure that the rotating wheel on the rotating shaft can rotate at a stable speed, providing a stable driving force for the capping rod; the opening slots are symmetrically arranged on the guide tube, and the rim of the rotating wheel is placed in the opening slot and abuts against the capping rod, which can realize that the rotating wheel controls the movement of the capping rod through the opening slot, so that the capping rod is smoothly conveyed along the predetermined direction.

[0011] Optionally, the shearing mechanism includes a blade and a second electric telescopic rod; the upper end of the movable frame is provided with a horizontally arranged transverse slide rail, and a movable plate is slidably connected in the transverse slide rail. The movable plate is powered by the second electric telescopic rod to move laterally; the blade is fixed on the movable plate and is used to cut the capping rod output from the outlet end of the guide tube.

[0012] By adopting the above technical solution, the blade is slidably connected to the transverse slide rail via the moving plate. The second electric telescopic rod provides the power for the transverse movement of the moving plate. By controlling the extension and retraction of the second electric telescopic rod, the blade can move in a set direction, improving the consistency and accuracy of cutting. In addition, the transverse slide rail provides guidance for the movement of the blade, ensuring that the blade can move in the set direction and avoiding blade position deviation during cutting, which would result in uneven cutting.

[0013] Optionally, the blades are arranged at an angle, enabling them to sequentially cut several capping rods output from the guide tubes.

[0014] By adopting the above technical solution, the oblique cutting edge of the blade can ensure that when the blade is close to the capping rod, it can cut the capping rods output from several guide tubes one by one, thereby reducing the load on the blade, extending the blade's service life, and reducing the energy consumption of the equipment.

[0015] Optionally, the upper part of the active frame is provided with a detection component for detecting the distance between the upper part of the active frame and the pie.

[0016] By adopting the above technical solution, the detection component set at the upper end of the active frame can detect the distance between the upper end of the active frame and the conveyor belt in real time, which improves the accuracy of the distance from the outlet end of the guide tube to the top of the pie and optimizes the covering effect.

[0017] Optionally, the detection component is an infrared ranging sensor, and the infrared ranging sensor and the height adjustment device are electrically connected to the control unit of the equipment.

[0018] By adopting the above technical solution, the control unit can automatically adjust the height of the movable frame based on the distance data fed back by the infrared ranging sensor, enabling the equipment to adapt to pies of various thicknesses without manual intervention, thus improving the automation level of the equipment.

[0019] Optionally, an extended guide plate is provided parallel to the inlet end of the guide tube.

[0020] By adopting the above technical solution, the extended guide plate arranged parallel to the inlet end of the guide tube can not only extend the transport length of the cap rod, but also reduce the weight of the guide tube, making it easier for the height adjustment device to adjust the height of the movable frame; in addition, the parallel arrangement of the extended guide plate makes it easy to intuitively observe the length of the remaining cap rod in the guide tube, improving the convenience of operation.

[0021] Optionally, the conveyor belt is equipped with trays for holding pies.

[0022] By adopting the above technical solution, a tray is placed on the conveyor belt. On the one hand, it can isolate the pie from the conveyor belt, reducing the potential contamination caused by direct contact between the pie and the conveyor belt. On the other hand, the tray is easy to pick up and remove for cleaning and disinfection, which also reduces the difficulty of cleaning the conveyor belt and extends its service life.

[0023] Optionally, triangular reinforcing ribs are provided at the corners of the movable frame.

[0024] By adopting the above technical solution, the triangular reinforcing ribs can increase the thickness and support area at the corners of the movable frame, thereby enhancing the overall strength of the movable frame. During the operation of the conveying mechanism, the force generated is transmitted to the corners through the movable frame, and the triangular reinforcing ribs can disperse these forces, extending the service life of the movable frame.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. This application ensures that the cut capping rods have the same thickness by setting a shearing mechanism on the active frame for cutting the capping rods output from the outlet end of the guide tube, thereby improving product consistency. Furthermore, the automated cutting process can improve work efficiency. 2. The height adjustment mechanism can adjust the height of the movable frame to ensure that the guide tube arranged on the movable frame maintains a set distance from the pie. On the one hand, it can cover pies of different thicknesses, and on the other hand, it makes it easy for the cut cover to fall accurately onto the pie. 3. This application sets up a conveying mechanism so that the cover bar in the guide tube can move towards the outlet end of the guide tube at a set speed, ensuring that the moving speed of the cover bar can match the shearing frequency of the shearing mechanism, so as to cut the cover bar into pie crusts of the same thickness.

[0028] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Example 1 Reference Figure 1 This application discloses a pie crust covering device, including a frame 1. A vertical slide rail 11 is provided on the side wall of the frame 1, and a movable frame 2 is slidably connected in the vertical slide rail 11. The upper end of the movable frame 2 is provided with several vertically arranged guide tubes 21, which are used to place crust covering rods 9. The outlet end of each guide tube 21 extends to the middle of the movable frame 2, and an opening groove 211 is provided on the side wall of the guide tube 21 near the outlet end. A conveying mechanism 4 is provided at the opening groove 211 to abut against the crust covering rods 9. The feeding mechanism 4 is used to move the lid stick 9 in the guide tube 21 downward at a set speed; the movable frame 2 is provided with a cutting mechanism 5; the cutting mechanism 5 is used to cut the lid stick 9 output from the outlet end of the guide tube 21, and a conveyor belt 6 is provided below the cutting mechanism 5, the conveyor belt 6 is used to convey the pie; the lower end of the movable frame 2 is connected to a height adjustment device 3, the height adjustment device 3 is used to adjust the distance between the outlet end of the guide tube 21 and the conveyor belt 6, so as to ensure that the distance from the outlet end of the guide tube 21 to the top of the pie is at a set value.

[0030] Specifically, refer to Figure 1A pie crust covering device includes a frame 1. To meet the needs of covering pies of different thicknesses, two vertical slide rails 11 are arranged parallel to each other on the side wall of the frame 1. The vertical slide rails 11 are connected to a height adjustment device 3 via a movable frame 2 that is slidably connected. The height adjustment device 3 includes a first electric telescopic rod 31. By controlling the extension and retraction of the first electric telescopic rod 31, the height of the movable frame 2 is controlled to ensure that the outlet end of the guide tube 21 is kept at a suitable distance from the top of the pie. An extension guide plate 212 is arranged parallel to the inlet end of the guide tube 21, which can both extend the transport length of the crust covering rod 9 and reduce the weight of the guide tube 21. The movable frame 2 is made of high-strength aluminum alloy material, which ensures the structural stability of the movable frame 2 while making the movable frame 2 lighter, making it easy to move on the vertical slide rails 11 and adjust the height of the movable frame 2. Triangular reinforcing ribs 23 are welded at the corners of the movable frame 2. The triangular reinforcing ribs 23 are made of high-strength stainless steel material, which enhances the structural stability of the movable frame 2. To achieve automated transportation of pies, a conveyor belt 6 is provided below the guide tube 21, and a tray 8 for holding pies is placed on the conveyor belt 6. The tray 8 not only isolates the pies from the tray 8 to ensure food safety, but also reduces the amount of dirt residue on the surface of the conveyor belt 6, reduces the frequency and difficulty of cleaning, and extends the service life of the conveyor belt 6. The bottom of the frame 1 is equipped with casters 12 to facilitate the movement of the equipment and adapt to different operating environments.

[0031] refer to Figures 2-4An opening groove 211 is provided on the side wall of the guide tube 21 near the outlet end. A conveying mechanism 4 is provided at the opening groove 211 to abut against the cover bar 9. The conveying mechanism 4 includes a motor and a rotating shaft 41 connected to the movable frame 2. The motor is located inside the frame 1 and is not shown in the figure. There are two rotating shafts 41, which are rotatably connected to the middle of the movable frame 2 and are arranged parallel to each other on the outside of the opening groove 211. Several rotating wheels 42 are fitted on each rotating shaft 41. The rim of the rotating wheels 42 is placed in the opening groove 211 and abuts against the cover bar 9. The motor on the movable frame 2 drives the rotating shaft 41 to rotate, which in turn drives the rotating wheels 42 to rotate in the direction of the opening groove 211. Through the opening groove 211, the cover bar 9 in the guide tube 21 is pushed to move towards the outlet end of the guide tube 21 at a set speed, ensuring that the guide tube... The cover bar 9 output from the outlet end of 21 always passes through the shearing mechanism 5 at a set speed; the rotating wheels 42 on both sides of the cover bar 9 can provide stable support for the movement of the cover bar 9, reducing the friction between the cover bar 9 and the inner wall of the guide tube 21; the shearing mechanism 5 drives the moving plate 53 to slide in the transverse slide rail 22 by controlling the extension and retraction of the second electric telescopic rod 52, thereby ensuring that the blade 51 connected to the moving plate 53 reciprocates at a stable speed at the outlet end of the guide tube 21. At this time, in conjunction with the rotating wheels 42 that transport the cover bar 9 at a set speed, it can ensure that the cover bar 9 is cut into pie crusts of the same thickness; in this embodiment, the cutting direction of the blade 51 is parallel to the arrangement direction of the guide tube, which can realize the simultaneous cutting of several cover bars 9 output from the guide tube 21 at one time, realizing mass production and improving production efficiency.

[0032] The implementation principle of this embodiment is as follows: The first electric telescopic rod 31 can extend and retract according to the thickness of the pie crust as needed, driving the movable frame 2 to slide along the vertical slide rail 11. At the same time, the guide tube 21, conveying mechanism 4, and shearing mechanism 5 located on the movable frame 2 move together with the movable frame 2 to a suitable height. The motor of the conveying mechanism 4 drives the rotating shaft 41 to rotate through the belt, thereby causing the rotating wheel 42 to push the crust rod 9 in the guide tube 21 to move towards the blade 51 at a set speed through the opening slot 211. The shearing mechanism 5 controls the extension and retraction of the second electric telescopic rod 52, driving the moving plate 53 to slide in the horizontal slide rail 22, thereby causing the blade 51 connected to the moving plate 53 to reciprocate in a direction perpendicular to the movement direction of the crust rod 9, cutting the crust rod 9 into pie crusts of the same thickness. The conveyor belt 6 below the shearing mechanism 5 transports the tray 8 at a set speed, cooperating with the conveying mechanism 4 and the shearing mechanism 5 to ensure that the pie crust can accurately fall onto the pie in the tray 8.

[0033] Example 2 Reference Figures 5-6The difference between this embodiment and embodiment one is that in this embodiment, the blade 51 is a beveled blade 51. When the moving plate 53 slides in the transverse slide rail 22, the blade 51 reciprocates in the horizontal direction to cut the cover bar 9. When the blade 51 is close to the cover bar 9, the blade 51 can sequentially cut the cover bars 9 output by several guide tubes 21, reducing the pressure on the blade 51 during the cutting process and reducing energy consumption. The upper end of the movable frame 2 is provided with a detection component 7 for detecting the distance between the upper end of the movable frame 2 and the conveyor belt 6. In this embodiment, the detection component 7 is an infrared ranging sensor. The infrared ranging sensor includes a transmitter and a detector. As prior art, when the tray 8 enters the sensing area of ​​the infrared ranging sensor, the infrared ranging sensor transmits the detected sensing value to the control unit of the equipment. The control unit adjusts the height adjustment device 3 according to the preset value, ensuring the accuracy of the height adjustment device 3 and improving the automation level of the equipment.

[0034] The implementation principle of this embodiment is as follows: the oblique cutting edge of the blade ensures that when the blade 51 is close to the cover bar 9, it can cut the cover bars 9 output by the guide tube 21 one by one, thereby reducing the load on the blade, extending the service life of the blade 51, and reducing the energy consumption of the equipment; the control unit can automatically adjust the height of the movable frame 2 according to the distance data fed back by the infrared ranging sensor, so that the equipment can adapt to pies of various thicknesses without manual intervention, thus improving the automation level of the equipment.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
