Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of biscuit production and processing, and in particular relates to a biscuit filling device. Background Technology
[0002] Sandwich cookies are a type of snack food made by sandwiching fillings (such as cream, jam, chocolate, etc.) between two cookies. They are loved by many for the contrast between the crispy cookie and the smooth filling. The cookie filling device is the key equipment to achieve this delicious combination. It is usually integrated into the cookie production line and can accurately inject a certain amount of filling between two cookies or into the groove of a pre-formed single cookie. Through automated operation, it ensures that the filling is evenly distributed and the sandwich is firm, which not only improves production efficiency but also ensures the standardized quality of sandwich cookies. It is one of the indispensable core equipment for mass production of sandwich cookies in the food industry.
[0003] However, it still has the following drawbacks in actual use: During the filling and back-and-forth movement of the existing biscuit filling device, it is placed in the biscuit mold on the conveyor. Most of the existing molds are based on the inner diameter of the biscuit production. In order to facilitate neat stacking, the inner diameter is often slightly larger than the inner diameter of the biscuit. This will cause shaking during the filling process, which is prone to uneven filling and deviation. In the worst case, the biscuit may even flow out. Secondly, and most importantly, different inner diameter biscuits require special molds and different molds, which is costly and lacks universality. Utility Model Content
[0004] The purpose of this invention is to provide a biscuit filling device. This invention solves the problems of biscuit blanks being prone to displacement, poor adaptability, and inability to adapt to biscuits of different inner diameters in traditional filling devices by setting a fixed mold.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a biscuit filling device, including a main component and a fixed mold. The main component includes a belt conveyor, a filling mechanism is provided above the outlet end of the belt conveyor, a raw material hopper is provided at the inlet end of the belt conveyor, and a stacking roller is movably connected to the side wall of the raw material hopper. The fixed mold includes an outer frame fixed above the conveyor belt of the belt conveyor. A biscuit groove is provided on the upper surface of the outer frame. A mutually compatible transverse clamping member and a longitudinal clamping member are movably connected to the bottom of the biscuit groove. The fixed mold also includes a threaded rod rotatably connected to the bottom of the outer frame, a transverse clamping member protruding from one end of the biscuit slot and threadedly connected to the outer periphery of the threaded rod, and a spring rod horizontally fixed to the bottom of the outer frame, with the telescopic end of the spring rod fixed to the longitudinal clamping member protruding from one end of the biscuit slot.
[0006] Furthermore, the biscuit slots are arranged in a rectangular array of several, and the number of core injection nozzles of the core injection mechanism is the same as the number of biscuit slots distributed laterally.
[0007] Furthermore, each biscuit slot is equipped with two transverse clamps, two longitudinal clamps, and two spring rods. The threaded rod is a double-ended stud, and the two transverse clamps are mirror images of the two opposite threads on the threaded rod. The two spring rods and the two longitudinal clamps are also mirror images of each other.
[0008] Furthermore, a movable roller is rotatably connected to the transverse clamping member, and the movable roller is located on the contact surface between the transverse clamping member and the longitudinal clamping member. When the two transverse clamping members in the same biscuit slot separate, the longitudinal clamping member will also be driven to separate in a mirror image.
[0009] Furthermore, the threaded rods located on the same transverse straight line are all fixedly connected, and their outermost ends are also fixed with handles.
[0010] Furthermore, there are two stacking rollers.
[0011] This utility model has the following beneficial effects: 1. This utility model achieves stable fixing of biscuit blanks of different sizes by setting a fixed mold and adjusting the horizontal and vertical clamping parts. With the setting of multiple biscuit slots and corresponding filling gun heads, it effectively improves the filling efficiency and accuracy, and solves the problems of biscuit blanks being easy to deviate, poor adaptability and inability to adapt to biscuits of different inner diameters in traditional filling devices.
[0012] 2. This utility model, through the setting of a fixed mold, utilizes the unique appearance design of the transverse and longitudinal clamping parts during the lateral adjustment process. Both parts have inclined and closely attached sidewalls. When the transverse clamping parts separate, they will push the longitudinal clamping parts to separate as well. With the assistance of the movable roller, the two parts can move easily. When the two transverse clamping parts approach each other, the two longitudinal clamping parts will simultaneously approach each other under the push of the spring rod. This allows for the simultaneous adjustment of one side to drive the other side to change synchronously, greatly improving the structural compactness and solving the problem of structural redundancy caused by individual adjustment. It also improves the tightness of the linkage of the entire device structure. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Please see Figure 1-5 As shown, this utility model is a biscuit filling device, including a main component 1 and a fixed mold 2. The main component 1 includes a belt conveyor 11, a filling mechanism 12 is provided above the outlet end of the belt conveyor 11, a raw material hopper 13 is provided at the inlet end of the belt conveyor 11, and a stacking roller 14 is movably connected to the side wall of the raw material hopper 13.
[0017] The raw material silo 13 stores biscuit blanks (or semi-finished biscuits) to be filled. Two stacking rollers 14 are movably connected to the side wall of the raw material silo 13. Motors are installed at the ends of the rollers to drive them to rotate. When the biscuit blanks are discharged from the outlet of the raw material silo 13, the stacking rollers 14 perform preliminary sorting and guidance on the biscuit blanks to ensure that the biscuit blanks enter the biscuit slot 22 in a neat posture. The filling mechanism 12 is a device for mixing and dispensing biscuit fillings. All of these are existing technologies and will not be described in detail here.
[0018] The fixed mold 2 includes an outer frame 21 fixed above the conveyor belt of the belt conveyor 11. A biscuit groove 22 is provided on the upper surface of the outer frame 21. A transverse clamping member 23 and a longitudinal clamping member 24 are movably connected to the bottom of the biscuit groove 22. The fixed mold 2 also includes a threaded rod 25 rotatably connected to the bottom of the outer frame 21. The transverse clamping member 23 protrudes from one end of the biscuit groove 22 and is threaded to the outer periphery of the threaded rod 25. A spring rod 26 is also horizontally fixed at the bottom of the outer frame 21. The telescopic end of the spring rod 26 is fixed to the longitudinal clamping member 24 and protrudes from one end of the biscuit groove 22.
[0019] The fixed mold 2 is a device for fixing and conveying biscuits and placing them stably. The transverse clamping member 23 and the longitudinal clamping member 24 can adjust the inner diameter of the biscuit groove 22 to a certain extent, so as to adapt it to the processing of biscuits with different inner diameters.
[0020] Furthermore, the biscuit slots 22 are arranged in a rectangular array with several of them. The number of filling gun heads of the filling mechanism 12 is the same as the number of horizontally distributed biscuit slots 22. The biscuit slots 22 are arranged in a rectangular array, which can hold multiple sets of biscuit blanks at the same time, thereby improving production efficiency.
[0021] Furthermore, each biscuit slot 22 is provided with two transverse clamping members 23, two longitudinal clamping members 24, and two spring rods 26. The threaded rod 25 is a double-ended stud. The two transverse clamping members 23 are mirror images of the two opposite threads of the threaded rod 25. The two spring rods 26 and the two longitudinal clamping members 24 are also mirror images of each other.
[0022] The threaded rod 25 is a double-ended stud, which allows it to move synchronously apart or closer to each other, enabling the lateral clamping parts 23 on both sides to move synchronously. This is more efficient and structurally coherent than individual adjustment.
[0023] Furthermore, a movable roller 27 is rotatably connected to the transverse clamping member 23, and the movable roller 27 is disposed on the contact surface between the transverse clamping member 23 and the longitudinal clamping member 24. When the two transverse clamping members 23 in the same biscuit slot 22 separate, the longitudinal clamping member 24 will also be driven to separate in the same direction. The movable roller 27 can reduce the friction between the transverse clamping member 23 and the longitudinal clamping member 24, so that the original contact friction is transformed into the rolling friction of the movable roller 27, which can ensure better movement.
[0024] Furthermore, the threaded rods 25 located on the same horizontal straight line are all fixedly connected, and their outermost ends are also fixed with handles 28. The handles 28 facilitate manual rotation of multiple threaded rods 25 on a straight line, so that they can be better adjusted.
[0025] Furthermore, there are two stacking rollers 14. The two stacking rollers 14 can ensure the quality of biscuit stacking, so that there is as few cases as possible where there are no biscuits in the biscuit slot 22.
[0026] The specific working principle of this utility model is as follows: When using this device, the biscuit blank is placed in the raw material silo 13, the belt conveyor 11 is started, and the conveyor belt drives the fixed mold 2 to move synchronously. Under the action of the stacking roller 14, the biscuit blank enters the biscuit groove 22 for conveying. The biscuit groove 22 is provided with an adjustment component that can roughly adjust the inner diameter of the biscuit groove 22 to accommodate biscuits of different sizes. First, the handle 28 at the bottom of the outer frame 21 is rotated. The handle 28 drives the connected threaded rod 25 to rotate. Since the two transverse clamping parts 23 are respectively threaded to the two opposite threads of the threaded rod 25, when the threaded rod 25 rotates, the two transverse clamping parts 23 move in opposite directions or away from each other in the transverse direction (when moving in opposite directions, they clamp the transverse sides of the biscuit blank; when moving away from each other, they rotate in opposite directions). The transverse adjustment can be made according to the size of the biscuit. Through the synergistic action of the transverse and longitudinal clamping parts 24, it can accommodate biscuit blanks of different sizes, ensuring the stability of the biscuit blank position during the filling process and avoiding displacement.
[0027] During the lateral adjustment process, due to the unique appearance design of the lateral clamping member 23 and the longitudinal clamping member 24, both of which have inclined and close sidewalls, when the lateral clamping member 23 separates, it will push the longitudinal clamping member 24 to separate. With the assistance of the movable roller 27, the two can move easily. When the two lateral clamping members 23 approach each other, the two longitudinal clamping members 24 will also approach each other simultaneously under the push of the spring rod 26. This allows the adjustment of one side to drive the other side to change synchronously, greatly improving the compactness of the structure.
[0028] When the fixed mold 2 is conveyed by the belt conveyor 11 to the bottom of the filling mechanism 12, the belt conveyor 11 stops. The number of filling guns of the filling mechanism 12 is the same as the number of biscuit slots 22 distributed laterally, so that all biscuit blanks in the same horizontal direction can be filled at the same time. The filling material (such as cream, jam, etc.) is injected into the biscuit blank through the gun. After the filling is completed, the belt conveyor 11 continues to run, conveying the fixed mold 2 to the outlet end and entering the next round of production process.
[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
