Description

Technical Field

[0001] The utility model relates to the technical field of biscuit production, in particular to a processing device for sandwich biscuits. Background Art

[0002] As a popular snack food, the market demand for sandwich biscuits is constantly growing, driving the continuous progress of production technology. Among them, jam sandwich biscuits are highly favored by consumers for their sweet flavor and rich taste.

[0003] The production of traditional jam sandwich biscuits mainly relies on manual operation, with low efficiency and difficult to guarantee hygienic conditions. With the development of industrial automation, mechanized production has gradually replaced manual operation.

[0004] In the existing biscuit sandwiching device, there is a rotating barrel, and a plurality of sandwich discharge channels are arranged on the side wall of the barrel. The biscuit blanks to be sandwiched pass under the barrel. When the biscuit blanks pass under the barrel, they come into contact with the sandwich at the discharge port, realizing the coating of the sandwich on the biscuit blanks.

[0005] However, due to the need for a certain contact time between the sandwich biscuit blanks to ensure the adhesion of the filling, the sandwiching speed of the sandwiching device is limited, and it cannot meet the requirements of high-speed production.

[0006] Therefore, it is necessary to improve the existing processing device for sandwich biscuits to overcome the defects of the prior art. Summary of the Utility Model

[0007] In order to overcome the problems existing in the related art, the purpose of the utility model is to provide a processing device for sandwich biscuits to solve the problem of slow sandwiching speed in the prior art.

[0008] A processing device for sandwich biscuits, comprising:

[0009] A sandwich output drum, at least one sandwich discharge channel is arranged on the sandwich output drum, the sandwich discharge channel extends inward from the side wall of the sandwich output drum and communicates with the sandwich source, a spraying component is further arranged in the sandwich discharge channel, the spraying component communicates with a high-pressure gas source, and a triggering mechanism is further arranged in the sandwich output drum, and the triggering mechanism is used to control the communication between the spraying component and the sandwich discharge channel.

[0010] The sandwich filling is conveyed from the filling source to the sandwich output roller and flows out through the sandwich discharge channel on the side wall of the sandwich output roller. The high-pressure gas source is connected to the injection assembly, and the trigger mechanism controls the connection between the injection assembly and the sandwich discharge channel. When the sandwich discharge channel is facing the biscuit to be sandwiched, the trigger mechanism controls the injection assembly so that the gas flows from the high-pressure gas source to the sandwich discharge channel, spraying the sandwich filling onto the biscuit to be sandwiched, effectively reducing the time for the sandwich filling to be transferred to the biscuit to be sandwiched, and thus enabling the biscuit to be processed at a faster speed, improving the speed of sandwich processing.

[0011] Preferably, the injection assembly includes an air jet cylinder and a control valve disposed inside the air jet cylinder. The air jet cylinder is arranged along the axial direction of the sandwich discharge channel. The air jet cylinder includes a first end close to the sandwich output roller and a second end far from the sandwich output roller. The high-pressure gas source is connected between the first end and the control valve. An air outlet groove is also provided near the second end of the air jet cylinder, and the air outlet groove connects the air jet cylinder and the sandwich discharge channel.

[0012] The high-pressure gas enters the air jet cylinder from the gas source and is intercepted by the control valve. When it is necessary to spray the sandwich filling, the control valve opens, and the high-pressure gas enters the sandwich discharge channel through the air outlet groove on the air jet cylinder, cutting off the sandwich filling and spraying the sandwich filling onto the biscuit.

[0013] Preferably, along the direction from the high-pressure gas source to the air outlet groove, the control valve includes a control ring, a valve rod, a first spring, and a first fixing block arranged in sequence. The control ring and the first fixing block are fixed inside the air jet cylinder. The valve rod includes a rod portion and a plug. The radius of the plug is larger than the inner diameter of the control ring. The plug is disposed between the first fixing block and the control ring, and the first spring is disposed between the plug and the first fixing block.

[0014] The control ring and the first fixing block of the control valve are fixed inside the air jet cylinder. The valve rod is connected to the plug, and the plug relies on the elastic force of the first spring to closely adhere to the control ring, blocking the high-pressure gas from passing through. When it is necessary to spray the sandwich filling, the trigger mechanism pushes the valve rod, overcoming the spring resistance to move the plug away from the control ring, allowing the high-pressure gas to pass through, realizing gas injection, which can improve the triggering efficiency of the air jet and quickly close after the air jet is completed, improving the switching efficiency of the control valve.

[0015] Preferably, a trigger cavity is further provided inside the sandwich output roller. One end of the rod portion is connected to the plug, and the other end passes through the first end and extends into the trigger cavity. The trigger mechanism is disposed inside the trigger cavity. The trigger mechanism includes a hammer, and the hammer is used to strike the valve rod to move the plug away from the control ring.

[0016] A trigger chamber is arranged inside the sandwich output roller, and the valve stem extends into the trigger chamber. When the sandwich output roller rotates to a specific position, the hammer in the trigger chamber impacts the valve stem driven by the mechanism, opening the control valve to achieve precise ejection of the sandwich filling.

[0017] Preferably, the trigger mechanism further includes a second fixing block, which is arranged at the axis of the sandwich output roller. The sandwich output roller rotates around the second fixing block. A guide rail groove is arranged on the second fixing block, and the guide rail groove is arranged along the radial direction of the sandwich output roller. The hammer slides in the guide rail groove, and a second spring is further arranged between the hammer and the guide rail groove.

[0018] The hammer is restricted to slide in the guide rail groove on the second fixing block, and the second spring provides impact energy for the hammer. When triggering ejection is required, an external mechanism drives the hammer to compress the spring and store energy. Subsequently, the hammer rapidly impacts the valve stem under the action of the spring force to achieve precise triggering.

[0019] Preferably, a lifting block is arranged on the circumferential inner wall of the trigger chamber, and the lifting block corresponds to the rod part. Along the direction close to the rod part, the lifting block gradually extends inwards from the circumferential inner wall of the trigger chamber towards the center. When the lifting block rotates close to the hammer, the hammer compresses the second spring, and when the hammer leaves the lifting block, it impacts the valve stem.

[0020] The lifting block arranged on the circumferential inner wall of the trigger chamber rotates together with the sandwich output roller. When the lifting block rotates to below the hammer, it pushes the hammer to compress the spring. Subsequently, the lifting block leaves, and the hammer impacts the valve stem under the action of the spring force to complete the trigger. Triggering periodically through the mechanical structure can further improve the accuracy, stability, and reliability of the trigger.

[0021] Preferably, a pneumatic pressure regulating valve is further arranged between the air jet cylinder and the high-pressure gas source, and the pneumatic pressure regulating valve is used to maintain the air pressure at a rated value.

[0022] The pneumatic pressure regulating valve is installed between the high-pressure gas source and the air jet cylinder, and can automatically regulate the pressure of the gas entering the air jet cylinder to keep it at the set rated value, ensuring the stability of the sandwich filling ejection. At the same time, it can also ensure the force during each ejection to avoid damaging the sandwich cookies to be filled.

[0023] Preferably, the air outlet groove is arranged on the circumferential surface of the air jet cylinder, and an exhaust valve is further arranged in the air jet cylinder. The exhaust valve includes a blocking block and a third spring. The blocking block corresponds to the air outlet groove, and the third spring is arranged between the blocking block and the second end.

[0024] The gas outlet groove is arranged on the circumferential surface of the jet cylinder, and is used to guide the high-pressure gas into the sandwich outlet passage. The exhaust valve is installed inside the jet cylinder, and is used when the jet is not needed, the third spring lifts the block, and cuts off the connection between the gas outlet groove and the sandwich outlet passage, and prevents the sandwich filling from entering the jet cylinder. When the jet is in progress, the air pressure in the jet cylinder increases, and the block compresses the third spring, so that the gas is ejected from the gas outlet groove.

[0025] Preferably, there are six sandwich discharge channels, which are evenly arranged on the sandwich output roller, each of which is correspondingly provided with an injection assembly, and each of which corresponds to a lifting block.

[0026] Six sandwich discharging channels are evenly arranged on the sandwich discharging drum, and each discharging port corresponds to an ejection assembly and a lifting block. When the sandwich discharging drum rotates, the six lifting blocks cause the hammer to periodically strike and trigger the corresponding ejection assembly, and the six ejection assemblies can eject in turn without waiting for the sandwich to flow out of the sandwich discharging channel, which greatly improves the production speed of sandwich biscuits.

[0027] Preferably, it also includes a central axis, which passes through the sandwich output roller along the axial direction of the sandwich output roller, the second fixed block is fixed on the central axis, and the sandwich output roller rotates around the central axis. A sandwich input chamber and an air inlet chamber are respectively provided on both sides of the sandwich output roller, and the sandwich input chamber and the air inlet chamber are both fixed on the central axis. The sandwich input chamber is connected to the sandwich source, and each of the sandwich discharge channels is connected to the sandwich input chamber through a pipeline, and the air inlet chamber is connected to the high-pressure gas source, and each of the jet cylinders is connected to the air inlet chamber through a pipeline.

[0028] The sandwich output roller is fixed by the central axis and rotates around the central axis. The sandwich filling enters the sandwich input chamber from the sandwich source and is then transported to each sandwich outlet through the pipeline. The high-pressure gas enters the air inlet chamber from the gas source and is then transported to each jet cylinder through the pipeline. It can effectively solve the feeding and air delivery problems during the rotation process and avoid the winding and bending of the delivery pipeline during the rotation process.

[0029] The beneficial effects of the utility model are:

[0030] The present utility model provides a processing device for sandwich biscuits. The processing device for sandwich biscuits includes a sandwich output roller provided with a sandwich discharge port.

[0083] Double-Layer Injection Assembly 200:

[0084] 3. Double-Layer Structure Injection Assembly 200: The outer layer is connected to the sandwich discharge channel 110, and the inner layer is provided with a control valve 220 near one end of the rotation axis, and is connected to the high-pressure gas source near the other end away from the rotation axis.

[0086] 5. Electromagnetic trigger mechanism 300: It includes a solenoid valve controller and a sensor. The sensor detects the position of the biscuit blank. When the biscuit blank moves below the discharge channel, the sensor sends a signal to the controller, and the controller controls the solenoid valve to open. High-pressure gas enters the inner layer of the injection assembly 200, flows into the outer layer, and is ejected from the air outlet groove, ejecting the sandwich filling at the front end of the sandwich discharge channel 110.

[0087] 6. Sandwich input chamber 500: It is connected to the sandwich source, stores the sandwich filling to be ejected, and is connected to the sandwich discharge channel 110 through a pipeline.

[0091] 1. Preparation stage: The filling is pre-filled into the sandwich input chamber 500, and high-pressure gas is filled into the intake chamber 600. The biscuit blanks are fed into the biscuit transportation mechanism.

[0092] 2. Injection trigger: When the biscuit transportation mechanism transports the biscuit blank below the sandwich discharge channel 110, the sensor detects the biscuit blank and sends a signal to the solenoid valve controller.

[0093] 3. Solenoid valve opening: After receiving the signal, the controller controls the solenoid valve to open. High-pressure gas enters the inner layer of the injection assembly 200 from the intake chamber 600 through the pipeline, flows out of the outer layer, and is ejected from the exhaust groove.

[0094] 4. Filling injection: The high-pressure gas is ejected from the exhaust groove, and the filling is ejected onto the biscuit blank under the push of the gas pressure. The one-way plate prevents the filling from flowing back into the nozzle.

[0095] 5. Solenoid valve closing: After the filling injection is completed, the controller controls the solenoid valve to close and stops the supply of high-pressure gas.

[0096] 6. Biscuit blank transportation: After the filling injection is completed, the biscuit transportation mechanism transports the biscuit blanks that have completed the filling to the next process. At the same time, new biscuit blanks will be transported to the injection position to prepare for the next round of filling.

[0097] 7. Cyclic operation: The sandwich output roller 100 rotates continuously, cooperating with the biscuit transportation mechanism and the electromagnetic triggering mechanism 300 to achieve efficient and continuous processing of sandwich biscuits.

[0098] The sandwich biscuit processing device in this embodiment is controlled by a solenoid valve, with a single discharge channel and a double-layer air jet tube 210 designed, and a one-way plate is provided at the exhaust groove, which can obtain a faster response speed and higher spraying accuracy. The solenoid valve can accurately control the gas flow, making the filling spraying amount more uniform and the product quality more stable. The design of the one-way plate effectively prevents the filling from flowing back and avoids blocking the exhaust groove.
