Description

Technical Field

[0001] This utility model belongs to the field of sandwich biscuit production technology, and specifically relates to a sandwich biscuit forming equipment. Background Technology

[0002] Sandwich cookies are a popular type of baked snack, typically consisting of two crisp, regularly shaped cookie bases (such as round, square, or irregular shapes) sandwiching a soft, flavorful filling. During the forming process, the equipment first sends the bottom cookie base to the filling station, where the filling is precisely applied using a metering pump or scraper system. Then, the top cookie base is precisely picked up by a robotic arm or vacuum suction cup and placed on top of the filling. Finally, the drive mechanism drives the pressure plate to press down vertically, applying appropriate pressure to the stacked three-layer structure to ensure the filling is tightly bonded.

[0003] However, due to the inherent brittleness and low toughness of the biscuit base, tiny fragments or edge breakage are easily generated during conveyor belt turns, robotic gripping, stacking collisions, or pressing and shaping. In the low-humidity environment of the food production workshop, these dry biscuit particles are prone to friction with the pressing plate material, generating static charge, causing them to be firmly adsorbed onto the working surface of the pressing plate. These residues accumulate continuously, forming an irregular "debris film." When the pressing plate presses down on a new batch of sandwich biscuits, the attached debris is directly transferred to the biscuit surface, seriously affecting the cleanliness of the product's appearance, resulting in black spots, blemishes, or a foreign object feel, reducing consumer acceptance. Furthermore, the uneven pressure distribution caused by debris accumulation on the pressing plate surface reduces the actual contact area in some areas, causing excessive local pressure that cracks the biscuits, or insufficient pressure that makes the filling loose and easy to fall off. Moreover, the long-term accumulation of residue may breed microorganisms or attract pests, posing a food safety hazard. Therefore, operators need to frequently stop the machine to manually wipe the pressing plate. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a sandwich cookie forming equipment. After the pressing plate completes the pressing, the cookie residue on the pressing plate can be removed and collected by the cleaning brush plate, keeping the pressing plate clean, ensuring that the cookies are pressed evenly and have a smooth surface, avoiding cross-contamination, and reducing manual downtime for cleaning, thereby improving the continuous pressing production efficiency of sandwich cookies.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a sandwich biscuit forming equipment, including a mounting frame plate, multiple telescopic columns are provided on the top wall of the mounting frame plate, a sliding frame is provided between the telescopic ends of the multiple telescopic columns, multiple sliding frames are slidably arranged inside the sliding frame, a cavity block is provided inside each sliding frame and on the lower side of the sliding frame, a pressure plate is slidably arranged inside each cavity block, a spacing synchronous adjustment mechanism for adjusting the spacing between the pressure plates is provided inside the sliding frame, a cleaning and collection mechanism is provided on the rear side of the mounting frame plate, the cleaning and collection mechanism can brush off and collect the biscuit crumbs adhering to the pressure plates, a knob threaded post is threadedly connected to the internal threaded hole opened inside the cavity block, a docking hole is opened on the upper side of each pressure plate, and each knob threaded post is inserted into the adjacent docking hole respectively.

[0006] The cleaning and collection mechanism includes a slide rail located on the rear side of the mounting frame plate. A sliding placement plate is slidably installed inside the slide rail, and a receiving box is placed inside the sliding placement plate. A handle is located on the front side of the receiving box. A cleaning brush plate is located on the front side of the sliding placement plate. A lead screw is rotatably installed inside the slide rail. The rear side of the sliding placement plate is threadedly connected to the lead screw. An electric drive unit for driving the lead screw to rotate is located on the left side of the slide rail. The electric drive unit includes a second motor located on the left side of the slide rail. The output shaft of the second motor is connected to the left end of the lead screw through a coupling.

[0007] As a further improvement of this utility model, multiple mounting holes are respectively opened on the left and right sides of the interior of the mounting frame plate.

[0008] As a further improvement of this utility model, an electric push rod is provided on the upper side of the mounting frame plate, and the telescopic end of the electric push rod is connected to the upper side of the slide frame.

[0009] As a further improvement of this utility model, the spacing synchronization adjustment mechanism includes a bidirectional lead screw rotatably disposed inside the slide frame, multiple sliding frames being threadedly connected to the left and right corresponding ends of the bidirectional lead screw respectively, and a motor is disposed on the left side of the slide frame, the output shaft of the motor being connected to the left end of the bidirectional lead screw through a coupling.

[0010] As a further improvement of this utility model, a plurality of flexible pads are provided on the lower side of the pressure plate, and the pressure plate and the flexible pads are bonded together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, when the sandwich biscuit is conveyed to the bottom of the pressure plate, the conveyor belt stops, and the electric push rod drives the pressure plate to press down smoothly under the guidance of the telescopic column. The multiple food-grade flexible pads (such as silicone or polyurethane) set on its lower side can effectively buffer the impact force and evenly distribute the pressure, avoiding rigid contact that could cause the crisp biscuit to crack, the edges to break or the filling to spill out.

[0012] Secondly, when the shape of the sandwich cookie changes, the pressure plate can be quickly unlocked by rotating the screw thread of the knob counterclockwise, sliding it out of the cavity block and replacing it with a pressure plate that matches the shape of the new cookie. Then, the screw thread is tightened clockwise to complete the fixation. The whole process is tool-free, easy to operate, and precise in positioning. This modular quick-change design not only greatly shortens the changeover time and improves the equipment's adaptability to the production of various types and irregularly shaped cookies, but also ensures that sandwich cookies of different shapes are subjected to uniform force and fit tightly during the pressing process. This effectively avoids cracking, filling displacement, or poor molding caused by mismatched pressure plates, thereby ensuring consistent product quality and improving production efficiency.

[0013] Third, the electric push rod drives the pressure plate to reset to the cleaning position, and then the motor drives the lead screw to make the cleaning brush plate and the receiving box on the sliding plate move smoothly to the left along the slide rail. The brush plate efficiently scrapes away the residual debris on the surface of the pressure plate and the debris falls directly into the closed receiving box below. The receiving box is embedded inside the sliding plate and will not fall off during the movement, ensuring safe and reliable operation. At the same time, the brush plate is located away from the lead screw and slide rail, which effectively prevents debris from falling into the transmission parts and causing jamming or wear.

[0014] Fourth, when the spacing of the sandwich cookies on the conveyor belt is inconsistent, by controlling the motor to run, the bidirectional lead screw can be driven to rotate, which can simultaneously drive the sliding frames on both sides and the pressure plates in the cavity block to move towards or away from each other, flexibly adjusting the spacing between the pressure plates, thereby accurately adapting to the positions of cookies with different layouts.

Detailed Implementation

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 1 , 2 As shown in Figures 3 and 4, a sandwich cookie forming device includes a mounting frame plate 101. Multiple mounting holes 110 are respectively opened on the left and right sides of the interior of the mounting frame plate 101. Multiple telescopic columns 102 are provided on the top wall of the mounting frame plate 101. A sliding frame 103 is provided between the telescopic ends of the multiple telescopic columns 102. Multiple sliding frames 104 are slidably arranged inside the sliding frame 103. A cavity block 105 is provided inside each sliding frame 104 and on the lower side of the sliding frame 103. A pressure plate 106 is slidably arranged inside each cavity block 105. Multiple flexible... The pad 109 and the slide frame 103 are equipped with a spacing synchronous adjustment mechanism for adjusting the spacing of the pressure plates 106. A cleaning and collection mechanism is provided on the rear side of the mounting frame 101. The cleaning and collection mechanism can brush off and collect the biscuit crumbs adhering to the pressure plates 106. The internal threaded holes in the cavity block 105 are all threaded with knob threaded posts 108. Each pressure plate 106 has a mating hole on its upper side. Each knob threaded post 108 is inserted into the adjacent mating hole. An electric push rod 107 is provided on the upper side of the mounting frame 101. The telescopic end of the electric push rod 107 is connected to the upper side of the slide frame 103.

[0020] The forming device is installed on the conveyor belt of the sandwich biscuit production line by inserting the mounting bolts into the mounting holes 110. Then, the external stacking mechanism on the production line accurately covers another biscuit base sheet with the filling on the base sheet to complete the sandwich. When the sandwich biscuit with the stacked edges is conveyed to the lower side of the pressure plate 106 by the conveyor belt, the external conveyor belt will stop running. Then, the electric push rod 107 is opened by control. The telescopic end drives the pressure plate 106 on the slide frame 103 to move downward under the restriction of the telescopic column 102 and contact the upper end of the sandwich biscuit. It continues to move downward to lightly press the sandwich biscuit to make it firmly bonded for subsequent packaging, thereby realizing the pressing and shaping of the biscuit.

[0021] Multiple flexible pads 109 (usually made of food-grade silicone, polyurethane or elastic rubber) provided on the underside of the pressure plate 106 can buffer and evenly transmit force when pressing sandwich biscuits, preventing the rigid pressure plate 106 from directly contacting the crispy biscuits and causing them to crack.

[0022] When the shape of the sandwich cookie to be pressed changes, in order to achieve uniform pressure on the sandwich cookie, the pressure plate 106 needs to be replaced. By turning the knob threaded column 108 counterclockwise, it is screwed out from the mating hole at the upper end of the pressure plate 106. At this time, the operator can slide the pressure plate 106 out from the cavity block 105, slide the pressure plate 106 that matches the shape of the sandwich cookie into the cavity block, and then turn the knob threaded column 108 clockwise to screw it into the mating hole inside the newly replaced pressure plate 106, thereby achieving quick replacement of the pressure plate 106.

[0023] like Figure 1 , 2 As shown in Figures 3 and 4, the cleaning and collection mechanism includes a slide rail 301 located on the rear side of the mounting frame plate 101. A sliding placement plate 302 is slidably arranged inside the slide rail 301. A receiving box 303 is placed inside the sliding placement plate 302. A handle is provided on the front side of the receiving box 303. A cleaning brush plate 304 is provided on the front side of the sliding placement plate 302. A lead screw 305 is rotatably arranged inside the slide rail 301. The rear side of the sliding placement plate 302 is threadedly connected to the lead screw 305. An electric drive unit for driving the lead screw 305 to rotate is provided on the left side of the slide rail 301. The electric drive unit includes a second motor located on the left side of the slide rail 301. The output shaft of the second motor is connected to the left end of the lead screw 305 through a coupling.

[0024] When the sandwich biscuits are pressed multiple times, a significant amount of biscuit crumbs remain attached to the pressure plate 106. The electric push rod 107 is then controlled to move the pressure plate 106 upwards to its original position. At this point, the pressure plate 106 aligns with the cleaning brush plate 304. Next, the motor is activated, and its output shaft drives the lead screw 305 to rotate. This, in turn, causes the receiving box 303 on the sliding placement plate 302 and the cleaning brush plate 304 to move to the left under the constraint of the slide rail 301. The cleaning brush plate 304 then brushes away the remaining biscuit crumbs attached to the pressure plate 106. The biscuit crumbs brushed off fall into the receiving box 303 and are collected. After a certain amount of biscuit crumbs are collected in the receiving box 303, the personnel can remove the receiving box 303 from the sliding placement plate 302 through the handle for processing. When the sliding placement plate 302 moves, the receiving box 303 is located inside the sliding placement plate 302 and will not fall off during movement. In addition, when the cleaning brush plate cleans the biscuit crumbs on the pressure plate 106, it is far away from the lead screw 305 and will not drift into the lead screw 305 of the slide rail 301.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2As shown, the spacing synchronization adjustment mechanism includes a bidirectional lead screw 202 rotatably disposed inside the slide frame 103, and multiple sliding frames 104 are respectively threaded to the left and right corresponding ends of the bidirectional lead screw 202. A motor 201 is disposed on the left side of the slide frame 103, and the output shaft of the motor 201 is connected to the left end of the bidirectional lead screw 202 through a coupling.

[0026] When the spacing between the sandwich cookies to be pressed on the conveyor belt is not uniform, the motor 201 is turned on by controlling it to run. The output shaft drives the bidirectional lead screw 202 to rotate, which in turn drives the pressure plates 106 on both sides of the sliding frame 104 and inside the cavity block 105 to move towards each other, changing the spacing between the pressure plates 106, thereby pressing sandwich cookies with different spacing into shape.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
