Description

Technical Field

[0001] This invention relates to the field of pastry flipping and demolding technology, and more specifically, to a flipping and demolding machine. Background Technology

[0002] The trajectory design of traditional tilting chute typically causes a large vertical displacement of the baking tray during the tilting process. That is, while the baking tray rotates around the pin, the pin itself moves up and down significantly in the vertical direction within the chute. This motion mode requires the drive chain to do a lot of ineffective work to overcome the weight of the baking tray, increasing the energy consumption and mechanical load of the conveying system, while also accelerating the wear of the chain and sprockets, affecting the long-term stability of the equipment. Summary of the Invention

[0003] To address the above-mentioned shortcomings, this invention provides a flipping and demolding machine, which solves the technical problems of large vertical displacement of the baking tray and excessive ineffective work caused by existing flipping modes.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A flipping and demolding machine includes a baking tray, a base, and conveyor shafts located at both ends of the base. Each end of the conveyor shaft has a drive sprocket, and the drive sprockets have chains mounted on them. The chains are sleeved on the drive sprockets. The machine also includes: An annular groove is fixedly mounted on the base; The limiting tube is fixedly installed on the chain; A pin is installed through the limiting tube, with one end connected to the baking pan and the other end inserted into the annular groove. When the chain runs, it drives the limit tube and the baking tray to move. The annular groove constrains the movement trajectory of the pin and the baking tray to keep the baking tray moving stably. The upper end of the annular groove is provided with a notch, and a rotating block is provided in the notch with clearance fit. A through groove is provided on the side wall of the rotating block, and the through groove is provided along the diameter direction of the rotating block. The pin is inserted into the annular groove at one end with a rectangular protrusion. When the rectangular protrusion moves within the annular groove, the pin moves along the trajectory of the annular groove. When the rectangular protrusion moves into the through groove, the rotation of the rotating block can indirectly drive the baking pan to flip. A drive motor mounted on the base drives the baking tray to rotate.

[0005] Furthermore, the output end of the drive motor is directly connected to the rotating block.

[0006] Furthermore, a worm gear is installed at the output end of the drive motor, and a worm wheel that meshes with the worm gear is provided on the side wall of the rotating block. One worm gear drives multiple worm wheels at the same time, thereby driving multiple baking pans to rotate.

[0007] Furthermore, a portable disassembly assembly is provided between the pin and the baking tray. The portable disassembly assembly includes L-shaped springs on both sides of the baking tray. The side wall of the L-shaped springs is provided with square holes. One end of the pin is provided with a square block. The square block is inserted into the square hole. At this time, the square block provides support for the L-shaped springs and the baking tray.

[0008] Furthermore, the lower end of the square hole is beveled, and the upper end of the L-shaped spring is curved; the side wall of the square block is provided with a frustum protrusion.

[0009] Furthermore, the base is equipped with a feeding conveyor belt that is set at a 90° angle to the chain, and the feeding conveyor belt passes through the base.

[0010] Furthermore, a pulley is provided at the position where the rectangular protrusion contacts the annular groove.

[0011] Furthermore, the drive motor can rotate forward and reverse at high frequency, with a rotation angle of 1 degree. When the baking pan opening is facing down, it facilitates the removal of the baked goods.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: by fixing the annular groove on the base and providing a notch at the upper end of the annular groove, a rotating block is fitted with the notch with clearance, and a rectangular protrusion is provided at the end of the pin that extends into the annular groove, so that the rectangular protrusion is constrained by the trajectory when moving within the annular groove, thus keeping the baking tray moving stably. When the rectangular protrusion enters the through groove, the drive motor independently drives the rotating block to rotate the baking tray, thereby separating the translation and conveying of the baking tray from the rotation action. This makes the rotation action no longer dependent on the continuous trajectory drive of the annular slide, which can greatly reduce the vertical travel height of the annular slide, avoid the ineffective power consumption of the conveyor chain due to frequent lifting and lowering during the rotation process, reduce the energy consumption and mechanical wear of the equipment, and improve the transmission efficiency and running stability. By setting a portable disassembly component between the pin and the baking tray, a snap-fit ​​connection structure is formed by L-shaped springs on both sides of the baking tray and square holes on the side walls of the springs, which in turn cooperate with a square block at the end of the pin. In the assembled state, the square block provides reliable support for the L-shaped springs and the baking tray. When disassembling, simply press the L-shaped springs to disengage the square block from the square holes, achieving quick separation of the baking tray and the pin without the need for tools, which significantly improves the efficiency and convenience of disassembling, cleaning and replacing the baking tray.

[0014] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] Please see Figure 1-9 The present invention provides a flipping and demolding machine, including a baking tray 1, a base 2, and a conveyor shaft 3 disposed at both ends of the base 2. Drive sprockets 4 are provided at both ends of the conveyor shaft 3, and chains 401 are provided on the drive sprockets 4. The chains 401 are sleeved on the drive sprockets 4. The machine also includes: An annular groove 5 is fixedly mounted on the base 2; Limiting tube 6 is fixedly installed on chain 401; A pin 7 is installed through the limiting tube 6. One end of the pin 7 is connected to the baking tray 1, and the other end is inserted into the annular groove 5. When the chain 401 is running, it drives the limit tube 6 and the baking tray 1 to move. The annular groove 5 constrains the movement trajectory of the pin 7 and the baking tray 1 so that the baking tray 1 can move stably. The upper end of the annular groove 5 is provided with a notch 8, and a rotating block 9 is provided in the notch 8 with clearance fit. The side wall of the rotating block 9 is provided with a through groove 10, which is arranged along the diameter direction of the rotating block 9. A rectangular protrusion 11 is provided at one end of the pin 7 that is inserted into the annular slide groove 5. When the rectangular protrusion 11 moves in the annular slide groove 5, the pin 7 moves along the trajectory of the annular slide groove 5. When the rectangular protrusion 11 moves into the through groove 10, the rotation of the rotating block 9 can indirectly drive the baking pan 1 to flip. A drive motor 12 is installed on the base 2, which drives the baking tray 1 to flip.

[0016] In practical applications, the conveyor shaft 3 is equipped with an independent drive system. The rotation of the conveyor shaft 3 drives the sprocket 4 and the chain 401 to run continuously. The limiting tube 6, which is fixedly installed on the chain 401, moves synchronously with the chain. One end of the pin 7 that passes through the limiting tube 6 is connected to the baking tray 1, and the rectangular protrusion 11 at the other end is inserted into the annular groove 5 fixed on the base 2. Driven by the chain, the groove wall of the annular slide 5 constrains the movement trajectory of the rectangular protrusion 11, so that the pin 7 and the baking tray 1 move stably along the pre-set closed track of the annular slide 5, and keep the baking tray 1 in a stable posture in the non-flipping section. When the rectangular protrusion 11 moves with the pin 7 to the notch 8 at the upper end of the annular slide 5, the rectangular protrusion 11 is released from the constraint of the groove wall of the annular slide 5 and enters the through groove 10 opened along the diameter direction on the side wall of the rotating block 9 with clearance fit. At this time, the drive motor 12 drives the rotating block 9 to rotate around its own axis in the notch 8 through the transmission mechanism. The rotating block 9 drives the rectangular protrusion 11 in the through groove 10 to rotate around the center of the rotating block 9, and then forces the baking tray 1 to rotate accordingly through the pin 7 to complete the flipping action of the set angle; for example, flipping 180 degrees, at which time the baking tray 1 is facing down. After the material is unloaded, it is rotated 180 degrees again to reset. After the flipping is completed, the rotating block 9 rotates to the predetermined angle, and the rectangular protrusion 11 moves with the through groove 10 to the position where it docks with the subsequent trajectory of the annular slide 5. It then slides back into the groove of the annular slide 5, and the pin 7 and the baking tray 1 are again constrained by the trajectory of the annular slide 5, and continue to move stably along the closed track, thereby completing the entire flipping work cycle.

[0017] Example 1 of rotating block 9, see below Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The output end of the drive motor 12 is directly connected to the rotating block 9.

[0018] In practical applications, the output of the drive motor 12 is directly connected to the rotating block 9, and the drive motor 12 drives the single rotating block 9 to rotate when it rotates.

[0019] Example 2 of rotating block 9, see below Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The output end of the drive motor 12 is equipped with a worm gear 31, and the side wall of the rotating block 9 is provided with a worm wheel 32 that meshes with the worm gear 31. One worm gear 31 drives multiple worm wheels 32 at the same time, thereby driving multiple baking pans 1 to rotate.

[0020] In practical applications, the output of the drive motor 12 drives the worm gear 31 to rotate, and the worm gear 31 simultaneously drives multiple worm wheels 32 to rotate, which in turn indirectly drives the baking pan 1 to rotate.

[0021] Reference Figures 1 to 9 A portable disassembly assembly is provided between the pin 7 and the baking tray 1. The portable disassembly assembly includes L-shaped spring pieces 41 on both sides of the baking tray 1. The side wall of the L-shaped spring piece 41 is provided with a square hole 42. One end of the pin 7 is provided with a square block 43. The square block 43 is inserted into the square hole 42. At this time, the square block 43 supports the L-shaped spring piece 41 and the baking tray 1.

[0022] In practical applications, under the assembled state, the square block 43 is fixed to one end of the pin 7 and inserted into the square hole 42 on the side wall of the L-shaped spring sheet 41 on both sides of the baking tray 1. The L-shaped spring sheet 41 is in a natural elastic position. The square hole 42 and the square block 43 form a shape fit and engage. The square block 43 provides vertical support for the L-shaped spring sheet 41 and the baking tray 1, realizing a reliable connection between the pin 7 and the baking tray 1. When baking tray 1 needs to be disassembled, the operator manually presses the free end of the L-shaped spring piece 41 to cause the spring piece to bend and deform elastically. The square hole 42 moves with the spring piece and disengages from the outer contour of the square block 43, releasing the locking limit between the square hole 42 and the square block 43. While maintaining the pressing state, move it in the vertical direction so that the square block 43 completely exits from the square hole 42, and the pin 7 separates from the baking tray 1, completing the disassembly. During installation, align the square block 43 with the square hole 42 and push it in so that the square block 43 passes through the square hole 42. Then release the L-shaped spring piece 41. The spring piece returns to its natural position due to its own elasticity, and the square hole 42 re-engages the square block 43, restoring the support connection and completing the installation.

[0023] Reference Figures 1 to 9 The lower end of the square hole 42 is a bevel 402, and the upper end of the L-shaped spring piece 41 is bent; the side wall of the square block 43 is provided with a frustum protrusion 403.

[0024] In practical applications, manually pressing the curved part at the upper end of the L-shaped spring 41 causes the L-shaped spring 41 to undergo elastic deformation. The square hole 42 moves with the spring, and the inclined surface 402 at its lower end first contacts the edge of the square block 43. The inclined surface 402 converts the vertical displacement generated by pressing into a horizontal separation thrust, which facilitates the square hole 42 to slide smoothly out along the outer contour of the square block 43 and reduces the separation resistance. The convex truncated cone 403 is designed to prevent the baking pan 1 from shaking.

[0025] Reference Figures 1 to 9 The base 2 is equipped with a feeding conveyor belt 61 that is set at a 90° angle to the chain 401, and the feeding conveyor belt passes through the base 2.

[0026] In practical applications, the flipped material is transported to the outside via conveyor belt 61.

[0027] Reference Figures 1 to 9 A pulley 71 is provided at the position where the rectangular protrusion 11 contacts the annular groove 5.

[0028] In practical applications, the pulley 71 can reduce the friction between the annular groove 5 and the rectangular protrusion 11.

[0029] Reference Figures 1 to 9 The drive motor 12 can rotate forward and reverse at high frequency, with a forward and reverse rotation angle of 1 degree. When the opening of the baking tray 1 is facing down, it facilitates the removal of the baked goods.

[0030] In practical applications, when the baking pan 1 is flipped to face downwards and is in the demolding position by the rotating block 9, the drive motor 12 switches to high-frequency vibration mode, alternately performing forward and reverse rotation at a preset frequency. Each unidirectional rotation angle is limited to 1°, forming a high-frequency reciprocating oscillation output. This reciprocating oscillation is transmitted to the rotating block 9 through the transmission mechanism, causing the rotating block 9 to oscillate at the same frequency and small amplitude around its own axis within the notch 8 of the annular groove 5. The oscillation of the rotating block 9 is converted into the reciprocating micro-movement of the pin 7 and the baking pan 1 along the circumferential tangential direction through the cooperation of the through groove 10 and the rectangular protrusion 11, causing the baking pan 1 to generate high-frequency small-amplitude vibration. This vibration acts on the baking material in the baking pan 1, overcoming the adhesion between the baking material and the inner wall of the baking pan. At the same time, in conjunction with the downward-facing gravity direction, it promotes the baking material to smoothly detach from the baking pan. After demolding, the drive motor 12 stops the high-frequency oscillation or resets to the initial angle, preparing for the next work cycle.
