Description

Technical Field

[0001] This utility model relates to the field of biscuit processing, and in particular to a biscuit processing oil spreading mechanism. Background Technology

[0002] In the industrial production process of multi-layer sandwich cookies, conventional processes employ multiple sets of rolling devices arranged along the conveyor line. The dough is rolled into sheets by the equipment and then enters the conveying system. When the multi-layer sheets of dough are stacked in parallel, an adhesion effect occurs between the interfaces. This causes irreversible physical adhesion of the layered ingredients during subsequent proofing and dividing processes, resulting in defects such as structural collapse or uneven thickness. Ultimately, this affects the separation of the crisp layers and the flavor profile of the product.

[0003] To address the problem of dough sticking, existing technologies have proposed a multi-layered biscuit processing oil-spreading mechanism, such as Chinese Patent Application No. CN202420962544.5. This utility model discloses a multi-layered biscuit processing oil-spreading mechanism, including a panel, oil-soaked cotton, mounting components, bolts, and nuts. Oil-soaked cotton is adhered to the bottom surface of the panel, and mounting components are symmetrically fixed on both sides of the panel. Bolts are symmetrically arranged through the mounting components, and nuts and washers are threaded onto the surface of the bolts. This oil-spreading mechanism is fixedly mounted on a conveyor frame by bolts, so that the panel between the mounting components is supported above the conveyor belt. The thickness of the oil-spreading is adjustable. When the dough passes between the two, a layer of oil-spreading is evenly applied to the surface of the dough, preventing multiple layers of dough from completely sticking together. This facilitates distinct layers and a crisp texture during subsequent baking. This mechanism not only saves labor costs and ensures even oil-spreading but also prevents the dough from completely sticking together, effectively improving the multi-layered characteristics of the product and processing efficiency.

[0004] However, existing technologies similar to the aforementioned patents have the following problems: existing mechanisms require adjusting the height of the oil cotton with bolts, which is cumbersome and the accuracy depends on experience. After adjustment, the fixed height cannot adapt to changes in the thickness of the dough, which can easily lead to uneven application or excessive scratching, affecting the quality of the finished product. The process of replacing the oil cotton is complicated and requires frequent machine stops, which significantly reduces production efficiency.

[0005] Therefore, a biscuit processing oil-spreading mechanism is needed to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the problems of existing mechanisms requiring adjustment of the oil-soaked cotton height, the inability of the adjusted height to adapt to changes in dough thickness, and the complexity of oil-soaked cotton replacement, this utility model proposes a biscuit processing oil-spreading mechanism, the technical solution of which is as follows.

[0007] A biscuit processing oil spreading mechanism includes a mounting plate, which is mounted above a conveyor belt via mounting members on both sides.

[0008] A movable plate is arranged parallel to the mounting plate. The movable plate is positioned below the mounting plate via a movable mechanism and can move perpendicular to the surface of the mounting plate.

[0009] The movable mechanism includes several guide rods vertically arranged on the side of the movable plate near the mounting plate. Several movable through holes coaxial with the guide rods are opened on the mounting plate. The guide rods are coaxially and movably inserted into the movable through holes, and springs are coaxially sleeved on the guide rods. The two ends of the springs are fixedly connected to the movable plate and the mounting plate, respectively. A limiting fastening block is coaxially and movably sleeved on the end of the guide rod away from the movable plate. The limiting fastening block can be fixed to a designated position on the guide rod by a bolt movably screwed therein, thereby limiting the range of motion of the movable plate relative to the mounting plate and the distance of the movable plate relative to the conveyor belt.

[0010] The movable plate is equipped with an oil-cotton module plate via a quick-installation mechanism on the side closest to the conveyor belt.

[0011] Furthermore, the limiting fastening block has a threaded through hole, the axis of which is perpendicular to the axis of the guide rod. The bolt is coaxially screwed into the threaded through hole, and the guide rod can be fixed by tightening the bolt to make it press against the guide rod.

[0012] Furthermore, a guide protrusion is provided on one side of the guide rod along the axial direction, and a guide groove is provided on the side wall of the movable through hole along the axial direction. The guide protrusion and the guide groove cooperate to ensure that the guide rod can only translate along the axial direction in the movable through hole and cannot rotate about its own axis.

[0013] Furthermore, the guide rod has several positioning blind holes equidistantly spaced along the axial direction on the side opposite to the guide protrusion. The axis of the positioning blind holes is perpendicular to the axis of the guide rod, and the bolts in the limiting fastening block can be coaxially inserted into the positioning blind holes.

[0014] Furthermore, the oil-cotton module plate includes a plate body and an oil-cotton block fixed on the side of the plate body near the conveyor belt, the plate body being parallel to the conveyor belt.

[0015] Furthermore, the quick-assembly mechanism includes a T-slot opened on the side of the movable plate near the conveyor belt, and a T-shaped protrusion provided on the side of the plate near the T-slot. The T-slot is parallel to the plate, and one end of the T-slot is closed, while the other end is open for the T-shaped protrusion to be inserted coaxially along the direction of the T-slot.

[0016] Furthermore, the plate body is bent upward on the side facing the direction of conveyor belt movement to form an arc-shaped part.

[0017] Furthermore, a first magnetic block is embedded in the closed end sidewall of the T-slot, and a second magnetic block is embedded in the end face of the T-shaped protrusion. When the T-shaped protrusion is inserted into the closed end, the first magnetic block and the second magnetic block are magnetically attracted and fixed.

[0018] Furthermore, the T-shaped groove is perpendicular to the direction of conveyor belt movement, so that the opening is located on the side of the conveyor belt, which facilitates the installation and removal of the oil-cotton module plate.

[0019] This utility model has the following beneficial effects:

[0020] The movable plate achieves vertical floating through the cooperation of springs and guide rods. When the thickness of the biscuit blank on the conveyor belt fluctuates, the oil-cotton module automatically rises and falls with the movable plate, ensuring that the oil-cotton block always adheres to the surface of the biscuit blank, avoiding uneven coating or scratches caused by uneven biscuit blank thickness. The limiting fastening block locks the lifting range of the guide rod with bolts, preserving the elastic self-adaptive ability of the spring while preventing the oil-cotton module from sinking excessively and damaging the biscuit blank. The guide protrusion on the guide rod cooperates with the guide groove of the movable through hole to limit the guide rod to only move along the axis, combined with the precise positioning of the bolt locking position. Through the sliding cooperation of the T-slot and the T-protrusion, the oil-cotton module can be quickly disassembled and installed laterally from the side of the conveyor belt. With the adsorption positioning of the magnetic block, replacement can be completed without tools, significantly shortening maintenance time. The arc-shaped part of the oil-cotton module plate can smoothly guide the biscuit blank into the coating area, shortening the contact time difference between the biscuit blank and the oil-cotton in the high-speed production line and reducing the risk of material jamming.

[0026] The present invention will now be described with reference to the accompanying drawings:

[0027] like Figure 1As shown, a biscuit processing oil spreading mechanism includes a mounting plate 1, which is mounted on a conveyor belt 3 via mounting members 2 on both sides.

[0028] like Figure 2 As shown, a movable plate 4 is arranged parallel to the mounting plate 1. The movable plate 4 is arranged below the mounting plate 1 through a movable mechanism and can move perpendicular to the surface of the mounting plate 1.

[0029] like Figure 1 , Figure 2 As shown, the movable mechanism includes several guide rods 5 vertically arranged on the side of the movable plate 4 near the mounting plate 1. Several movable through holes 6 coaxial with the guide rods 5 are opened on the mounting plate 1. The guide rods 5 are coaxially inserted into the movable through holes 6, and springs 7 are coaxially sleeved on the guide rods 5. The two ends of the springs 7 are fixedly connected to the movable plate 4 and the mounting plate 1 respectively. Through the cooperation of the guide rods 5 and the springs 7, the movable plate 4 can float vertically, so that the oil-cotton module automatically conforms to the surface of the cake blank of different thicknesses, avoiding excessive compression or uneven coating. A limiting fastening block 8 is coaxially sleeved on the end of the guide rod 5 away from the movable plate 4. The limiting fastening block 8 can be fixed to a designated position on the guide rod 5 by a bolt 9 movably screwed therein, thereby limiting the range of movement of the movable plate 4 relative to the mounting plate 1 and the distance of the movable plate 4 relative to the conveyor belt 3. The limiting fastening block 8 locks the position of the guide rod 5 by the bolt 9, limiting the range of movement of the movable plate 4 and preventing the oil-cotton module from sinking excessively and damaging the cake blank.

[0030] like Figure 1 As shown, the movable plate 4 is equipped with an oil-cotton module plate on the side near the conveyor belt 3 via a quick-installation mechanism.

[0031] like Figure 1 , Figure 2 As shown, preferably, the limiting fastening block 8 has a threaded through hole 10, the axis of the threaded through hole 10 is perpendicular to the axis of the guide rod 5, and the bolt 9 is coaxially screwed into the threaded through hole 10. Tightening the bolt 9 to make it press against the guide rod 5 can fix the guide rod 5. The bolt 9 presses against the guide rod 5 vertically through the threaded through hole 10, which enhances the locking stability and prevents the guide rod 5 from having displacement errors during operation.

[0032] like Figure 1 , Figure 2As shown, preferably, a guide protrusion 11 is provided on one side of the guide rod 5 along the axial direction, and a guide groove 12 is provided on the side wall of the movable through hole 6 along the axial direction. The guide protrusion 11 and the guide groove 12 cooperate to ensure that the guide rod 5 can only move along the axial direction in the movable through hole 6 and cannot rotate around its own axis. The cooperation between the guide protrusion 11 and the groove ensures that the guide rod 5 can only move along the axial direction, eliminating the degree of rotational freedom, ensuring that the oil cotton module always moves vertically, avoiding the deflection of the oil cotton block 15 due to the twisting of the rod body, and ensuring the consistency of the application position.

[0033] like Figure 2 As shown, preferably, the guide rod 5 has a plurality of positioning blind holes 13 equidistantly opened on one side of the guide protrusion 11 along the axial direction. The axis of the positioning blind holes 13 is perpendicular to the axis of the guide rod 5. The bolts 9 in the limiting fastening block 8 can be coaxially inserted into the positioning blind holes 13. The positioning blind holes 13 are equidistantly distributed along the axis of the guide rod 5 to realize multi-level adjustment of the oil cotton height to adapt to different production needs. After the bolts 9 are inserted into the blind holes, the position can be locked instantly, avoiding the tedious operation of repeated calibration required in the past.

[0034] like Figure 3 As shown, preferably, the oil-cotton module plate includes a plate body 14 and an oil-cotton block 15 fixed on the side of the plate body 14 near the conveyor belt 3. The plate body 14 is parallel to the conveyor belt 3, ensuring that the contact surface between the oil-cotton block 15 and the cake surface is evenly stressed, preventing local overload or missed coating.

[0035] like Figure 3 , Figure 4 As shown, preferably, the quick-installation mechanism includes a T-slot 16 opened on the side of the movable plate 4 near the conveyor belt 3, and a T-shaped protrusion 17 provided on the side of the plate body 14 near the T-slot 16. The channel of the T-slot 16 is parallel to the plate body 14, and one end of the T-slot 16 is closed, while the other end is open for the T-shaped protrusion 17 to be coaxially inserted along the channel direction of the T-slot 16. The sliding insertion design of the T-slot 16 and the T-shaped protrusion 17 along the direction parallel to the plate body 14 allows the oil cotton module to be directly pushed in or pulled out from the side without disassembling equipment parts. The limiting structure at the closed end of the T-slot 16 prevents the module from slipping off, ensuring the safe operation on the high-speed production line.

[0036] like Figure 1 , Figure 3 As shown, preferably, the plate 14 bends upward on the side facing the conveyor belt 3 to form an arc-shaped part 18. The arc-shaped part 18 forms a transition slope in the direction of the biscuit entry, which avoids the edge of the biscuit from accidentally getting stuck with the oil and cotton module. It is suitable for high-speed continuous production. The arc-shaped surface reduces the frictional resistance when the biscuit comes into contact with the biscuit, ensuring that the oil and cotton block 15 applies uniform pressure to the biscuit.

[0037] like Figure 3 , Figure 4As shown, preferably, a first magnetic block 19 is embedded in the closed end sidewall of the T-slot 16, and a second magnetic block 20 is embedded in the end face of the T-shaped protrusion 17. When the T-shaped protrusion 17 is inserted into the closed end, the first magnetic block 19 and the second magnetic block 20 are magnetically attracted and fixed. When the oil cotton module is inserted into the closed end, the magnetic blocks are instantly attracted to achieve self-locking, preventing the module from shifting due to vibration or shaking. The magnetic attraction provides sufficient holding force but can still be manually separated, further improving maintenance efficiency.

[0038] like Figure 1 Figure 3 As shown, preferably, the T-groove 16 is perpendicular to the direction of movement of the conveyor belt 3, so that the opening is located on the side of the conveyor belt 3, which facilitates the installation and removal of the oil-cotton module plate. Operators can directly install and remove the oil-cotton module plate from the side without stopping the machine.

[0039] The following section details the operational steps and functional logic of this mechanism in conjunction with the technical solution:

[0040] Mounting plate 1 is placed above conveyor belt 3 of the biscuit production line using mounting pieces 2 on both sides, ensuring that movable plate 4 is perpendicular to the plane of conveyor belt 3. Based on the required biscuit thickness, the initial height of guide rod 5 is adjusted using bolts 9 on limiting fasteners 8: loosen bolts 9 on limiting fasteners 8, use positioning blind holes 13 for positioning, and slide guide rod 5 to the desired height. Tighten bolts 9 so that they press against guide rod 5 or are inserted into positioning blind holes 13, locking the initial height of movable plate 4. After starting conveyor belt 3, when the biscuit passes under the oil-cotton module plate, if the biscuit thickness exceeds the preset height: spring 7 is compressed and contracts, causing movable plate 4 and oil-cotton module plate to move upwards along guide rod 5, preventing excessive compression of the biscuit. When the biscuit thickness decreases, spring 7 rebounds, pushing movable plate 4 downwards, ensuring that oil-cotton block 15 always contacts the biscuit surface, achieving adaptive adjustment. When the oil-soaked cotton block 15 needs replacement or maintenance: Horizontally pull out the T-shaped protrusion 17 of the oil-soaked cotton module plate from the side of the conveyor belt 3 along the opening direction of the T-slot 16, releasing the attraction between the first magnetic block 19 and the second magnetic block 20. Insert the T-shaped protrusion 17 of the new oil-soaked cotton module plate along the opening of the T-slot 16 and push it horizontally to the closed end; the magnetic block will automatically attract and fix it. If wear is found on the oil-soaked cotton block 15 after long-term use, or if it causes coating deviation: Readjust the height of the guide rod 5 using the bolts 9 of the limiting fastening block 8.

[0041] If the spring elastic coefficient needs to be changed, the limit fastener 8 can be removed and the spring 7 replaced.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
