Description

Technical Field

[0001] This utility model relates to the field of product processing equipment technology, and in particular to a sandwich product stacking processing equipment. Background Technology

[0002] Sandwich foods typically consist of a bottom layer, a filling layer, and a top layer, with a stacking mechanism used to layer different ingredients to form the sandwich structure. Traditional stacking machines require manual transport of semi-finished products to the next process, resulting in low production efficiency and a high risk of food contamination. To address this issue, existing technology proposes an automated biscuit stacking solution that achieves biscuit handling, filling, and stacking through the coordinated operation of a pick-and-place mechanism and a filling injection mechanism. However, this technology is only suitable for fillings with low viscosity. For high-viscosity fillings, they form a continuous column when extruded, which existing filling injection mechanisms struggle to segment, making it difficult to accurately spread the filling onto the bottom layer. Utility Model Content

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a sandwich product stacking processing equipment, including a conveying mechanism. A lower layer dough feeding mechanism, a filling extrusion mechanism and an upper layer dough feeding mechanism are sequentially arranged on the conveying mechanism along its conveying direction. A filling cutting mechanism is arranged on both sides opposite to the filling extrusion mechanism. The filling cutting mechanism is arranged along the conveying direction of the conveying mechanism.

[0004] The filling cutting mechanism includes:

[0005] Third power unit;

[0006] The cutting frame is driven by a third power unit to move linearly in the direction parallel to the product conveying mechanism.

[0007] A pull rod, one end of which is ring-shaped, passes vertically through the end of the cutting frame and is fixed to the cutting frame;

[0008] A cutting line, one end of which is tied and fixed to the ring end of the pull rod, and the portion of the cutting line between the two sets of pull rods is in a taut state.

[0009] This invention is applicable to layered sandwich products with high-viscosity fillings. By using a third power unit to drive the linear movement of the cutting line, it can quickly cut and extrude high-viscosity fillings such as ice cream into columnar shapes, solving the problem of difficult filling layering caused by the inability of traditional filling injection mechanisms to segment continuous filling columns. Furthermore, through the coordinated operation of the conveying mechanism and other mechanisms, this invention achieves full automation from laying the lower layer, extruding and cutting the filling, to covering the upper layer, thus improving production efficiency.

[0010] Furthermore, the outer circumferential surface of the pull rod is provided with an external thread, and the cutting frame is clamped by two sets of first nuts that match the external thread, so that the pull rod and the cutting frame remain relatively fixed.

[0011] At both ends of the cutting frame, there are fixed rods perpendicular to the cutting frame. The two sets of fixed rods are arranged between the two sets of pull rods. At the end of the fixed rod, there is a guide wheel that rotates relative to the fixed rod. The annular surface of the guide wheel has a limiting groove for accommodating the cutting line. The cutting line is wound in the limiting groove.

[0012] The locking structure, which fixes the pull rod to the cutting frame by matching the external thread of the pull rod with the double nuts, allows the cutting wire to be tightened or loosened by loosening the nuts and sliding the pull rod, thereby adjusting the tension of the cutting wire. The limit groove set on the guide wheel ring surface can limit the position of the cutting wire, thereby improving the installation and positioning accuracy of the cutting wire. Furthermore, when pulling the cutting wire, the rotation of the guide wheel can reduce the wear on the cutting wire.

[0013] Furthermore, the filling extrusion mechanism includes:

[0014] The discharge pipe is provided in multiple sets, which are connected to the raw material extrusion equipment. The raw material is extruded from the discharge pipe by the raw material extrusion equipment. The multiple sets of discharge pipes are arranged above the conveying mechanism and are equidistantly arranged along the conveying direction perpendicular to the conveying mechanism.

[0015] The second power unit drives the lifting and lowering of multiple sets of discharge pipes.

[0016] By setting up multiple sets of discharge pipes and cooperating with the extrusion feeding of raw material extrusion equipment, the extrusion operation of multiple filling columns can be completed simultaneously, improving work efficiency. The distance between the discharge pipe and the conveyor belt can be adjusted by the lifting motion driven by the second power unit.

[0017] Furthermore, both the upper and lower sub-stripping mechanisms include:

[0018] The material storage section includes a feeding plate with an inlet and an outlet. The bottom of the inlet is provided with a feeding channel that communicates with the outlet. The raw material slides from the inlet to the outlet through the feeding channel. Multiple limiting rods that are vertically fixed to the surface of the feeding plate are arranged around the outside of the inlet. The multiple limiting rods arranged around the same inlet together form a limiting material storage section.

[0019] A feeding mechanism is fixedly installed on the side of the feed plate. The feeding mechanism pushes the raw material at the bottom of the feed inlet along the feeding channel to the discharge outlet.

[0020] A material blocking mechanism is fixedly installed on the side of the material discharge plate, and the material outlet is opened and closed by the material blocking mechanism.

[0021] Furthermore, a guide channel is provided on the side of the feeding plate near the feed inlet to connect the feeding channel with the outside.

[0022] Both the feeding mechanism and the blocking mechanism include:

[0023] First power unit;

[0024] The movable plate is slidably disposed in the guide channel or below the discharge port, and is driven to move linearly by the first power device.

[0025] The storage structure formed by the limiting rod can temporarily store a certain amount of raw materials and keep the raw materials vertically aligned. The feeding mechanism pushes the raw materials that fall from the storage section to the bottom of the inlet along the feeding channel to the outlet. Then, the blocking mechanism opens the outlet to allow the raw materials to fall out, thus realizing automatic feeding of raw materials.

[0026] Furthermore, the processing equipment also includes a product extrusion mechanism, which is integrally located on the side of the upper sub-skin material mechanism away from the filling cutting mechanism and is fixedly installed on the conveying mechanism;

[0027] The product extrusion mechanism includes:

[0028] Fourth power unit;

[0029] The pressure plate is positioned above the conveying mechanism and is driven to move vertically by a fourth power device.

[0030] The fourth power unit drives the pressure plate to move vertically, so that the pressure plate squeezes the upper layer of dough, thereby compacting the upper and lower layers of dough and filling.

[0031] Furthermore, the conveying mechanism is a chain plate conveyor line. Several holes are opened on the surface of the chain plate of the chain plate conveyor line. The several holes are arranged linearly and equidistantly along the length direction of the chain plate. At the discharge end of the chain plate conveyor line, a pushing mechanism and a lifting mechanism are arranged in sequence along the conveying direction. The pushing mechanism is fixedly installed above the connecting conveyor line. The lifting mechanism is set between the carrying section and the return section of the chain plate conveyor line.

[0032] The pushing mechanism includes:

[0033] Fifth power unit;

[0034] The pusher is connected to the fifth power unit, which drives the pusher to move linearly in the direction parallel to the conveying mechanism for conveying products.

[0035] The top-feeding mechanism includes:

[0036] The sixth power unit is fixed to the chain conveyor line;

[0037] The material ejector is provided in multiple parts, and the multiple material ejector parts are provided with corresponding holes. The sixth power device drives the multiple material ejector parts to move linearly along the axial direction of the holes.

[0038] The product is lifted to a preset height by the top feeding mechanism, and then pushed to a higher position by the pushing mechanism, thereby realizing the transfer of the product from the lower position line to the higher position line.

[0039] Furthermore, a plurality of limiting posts are provided on the surface of the chain plate, and the plurality of limiting posts are arranged around the periphery of the hole, and the limiting posts are arranged based on the shape of the product;

[0040] The limiting post and the edge of the hole maintain a preset distance in a direction parallel to the surface of the chain plate, so as to form a support platform that contacts the lower surface of the product.

[0041] The limiting posts are arranged based on the contour of the lower surface of the product, and maintain a distance from the edge of the hole to form a support platform, thereby improving the horizontal positioning accuracy of the product.

[0042] This utility model has the following advantages:

[0043] This invention is applicable to layered sandwich products with high-viscosity fillings. By using a third power unit to drive the linear movement of the cutting line, it can quickly cut and extrude high-viscosity fillings such as ice cream into columnar shapes, solving the problem of difficult filling layering caused by the inability of traditional filling injection mechanisms to segment continuous filling columns. Furthermore, through the coordinated operation of the conveying mechanism and other mechanisms, this invention achieves full automation from laying the lower layer, extruding and cutting the filling, to covering the upper layer, thus improving production efficiency.

[0071] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0072] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0073] As described in the background section, for high-viscosity fillings such as ice cream fillings, when they are extruded, they form a continuous column of filling, which is difficult for existing filling mechanisms to divide, and thus cannot effectively and accurately spread the filling onto the lower layer of skin.

[0074] Example 1:

[0075] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a sandwich product stacking processing equipment, such as... Figure 1 As shown, the processing equipment includes a conveying mechanism 100, on which a lower layer skin feeding mechanism 200, a filling extrusion mechanism 300 and an upper layer skin feeding mechanism 500 are arranged sequentially along the conveying direction. A filling cutting mechanism 400 is arranged on both sides opposite to the filling extrusion mechanism, and the filling cutting mechanism is arranged along the conveying direction of the conveying mechanism.

[0076] like Figure 8 As shown, the filling cutting mechanism includes:

[0077] Third power unit 410;

[0078] The cutting frame 440 is driven by a third power unit to move linearly in the direction parallel to the product conveying mechanism;

[0079] A pull rod 460 has a ring-shaped end and passes vertically through the end of the cutting frame, where it is fixed to the cutting frame.

[0080] Cutting line 470, one end of which is tied and fixed to the ring end of the pull rod, and part of the cutting line between the two sets of pull rods is in a taut state.

[0081] In this embodiment, the lower layer feeding mechanism first places the lower layer raw material skin onto the conveying mechanism. The conveying mechanism then moves the lower layer raw material skin towards the filling extrusion mechanism. When the lower layer raw material skin reaches below the filling extrusion mechanism, the ice cream filling is extruded downwards through the filling extrusion mechanism, forming a filling column. After the filling is extruded to a preset length, the filling cutting mechanisms located on both sides of the filling extrusion mechanism are simultaneously activated. That is, the third power device drives the cutting frame to move towards the filling column, so that the bidirectional cutting lines act on the filling column simultaneously, cutting the filling column into pieces. The cut pieces of filling fall onto the surface of the lower layer raw material skin under their own weight. Then, the conveying mechanism continues to move the lower layer raw material skin containing the filling. When it reaches below the upper layer feeding mechanism, the upper layer feeding mechanism places the upper layer raw material onto the filling surface, completing the layering of the sandwich food. This process is repeated.

[0082] This embodiment is applicable to layered sandwich products with high-viscosity fillings. A third power unit drives the linear movement of the cutting line, quickly cutting and extruding high-viscosity fillings such as ice cream into columnar shapes, solving the problem of difficult filling layering caused by the inability of traditional filling injection mechanisms to segment continuous filling columns. Simultaneously, this invention, through the coordinated operation of the conveying mechanism 100 and other mechanisms, achieves full automation from laying the lower layer of skin, extruding and cutting the filling, to covering the upper layer, thus improving production efficiency.

[0083] In this embodiment, the third power device includes, but is not limited to, a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or other devices capable of driving the cutting frame to move linearly. The filling cutting mechanism may also include a third fixing part 430, which may include a third fixing part and a third threaded rod. The third fixing part is fixedly installed on the conveying mechanism and has a third threaded sleeve that is threadedly engaged with the third threaded rod. The third power device may be fixedly installed on the first mounting part 430, the end of which is penetrated by the third threaded rod. The end of the first mounting part is clamped by two sets of nuts that match the third threaded rod, so that the first mounting part and the third threaded rod remain fixed.

[0084] For example, the outer circumferential surface of the pull rod may be provided with external threads, and the cutting frame is clamped by two sets of first nuts that match the external threads, so that the pull rod and the cutting frame remain relatively fixed.

[0085] In addition, fixed rods 450 perpendicular to the cutting frame are fixed at both ends of the cutting frame. The two sets of fixed rods are arranged between the two sets of pull rods. A guide wheel 480 that rotates relative to the fixed rod is provided at the end of the fixed rod. The annular surface of the guide wheel has a limiting groove for accommodating the cutting line. The cutting line is wound in the limiting groove.

[0086] This embodiment features a locking structure that fixes the pull rod to the cutting frame by matching the external thread of the pull rod with the double nuts. By loosening the nuts and sliding the pull rod, the cutting wire can be tightened or loosened, thereby adjusting the tension of the cutting wire. A limiting groove is provided on the guide wheel ring surface to restrict the position of the cutting wire, thereby improving the installation and positioning accuracy of the cutting wire. Furthermore, when pulling the cutting wire, the rotation of the guide wheel can reduce wear on the cutting wire.

[0087] For example, such as Figure 9 As shown, the filling extrusion mechanism may include:

[0088] The discharge pipe 340 is provided with multiple sets of discharge pipes. The multiple sets of discharge pipes are connected to the raw material extrusion equipment. The raw material is extruded out of the discharge pipe by the raw material extrusion equipment. The multiple sets of discharge pipes are arranged above the conveying mechanism and are equidistant along the conveying direction perpendicular to the conveying mechanism.

[0089] The second power unit 320 drives the lifting and lowering of multiple sets of discharge pipes.

[0090] By setting up multiple sets of discharge pipes and cooperating with the extrusion feeding of the raw material extrusion equipment, the extrusion operation of multiple filling columns can be completed simultaneously, improving the operating efficiency. The lifting motion driven by the second power unit 320 can realize the adjustment of the distance between the discharge pipe and the conveyor belt.

[0091] In this embodiment, the second power device includes, but is not limited to, a cylinder, an electric cylinder, a hydraulic cylinder, or other devices capable of driving the vertical linear movement of multiple sets of discharge pipes; the filling extrusion mechanism may also include a second fixing part 310, on which the second power device can be fixedly installed; the filling extrusion mechanism may also include a slide 330, on which multiple sets of discharge pipes are fixedly installed; the slide is slidably installed on the second fixing part and connected to the second power device; the second fixing part may be a frame with a guide rod, or a frame with a guide rail, or a frame with other guiding functions.

[0092] In this embodiment, the upper sub-sub-material mechanism and the lower sub-sub-material mechanism have the same structure, such as... Figure 2 As shown, the lower layer submersible material mechanism includes:

[0093] Storage section 210, such as Figure 3 As shown, the storage section includes a feeding plate 215, as... Figure 4 As shown, the feeding plate has an inlet 212 and an outlet 213. The bottom of the inlet is provided with a feeding channel 214 that communicates with the outlet. Raw materials slide from the inlet to the outlet through this feeding channel. Figure 3 As shown, multiple limiting rods 211 vertically fixed to the surface of the feed plate are arranged around the outside of the feed inlet. The multiple limiting rods arranged around the same feed inlet together form a limiting storage part.

[0094] The feeding mechanism 240 is fixedly installed on the side of the feed plate. The feeding mechanism pushes the raw material at the bottom of the feed port to move along the feeding channel to the discharge port.

[0095] A material blocking mechanism 230 is fixedly installed on the side of the material discharge plate, and the material outlet is opened and closed by the material blocking mechanism.

[0096] For example, such as Figure 5 As shown, a guide channel 216 connecting the feeding channel to the outside can be provided on the side of the feeding plate near the feeding port;

[0097] In this embodiment, the feeding mechanism and the blocking mechanism have the same structure, wherein, as shown in the example... Figure 6 As shown, the material stopping mechanism includes:

[0098] First power unit 231;

[0099] Movable plate 233 is slidably disposed in the guide channel or below the discharge port, and is driven to move linearly by the first power device.

[0100] Specifically, such as Figure 7 As shown, raw hides are stacked in the limiting storage section formed by the limiting rods. Under their own gravity, they slide down, with the bottom hides reaching the bottom of the inlet. At this point, the first power unit of the feeding mechanism drives the corresponding movable plate to move linearly. Since the movable plate of the feeding mechanism has a feeding part 241 that matches the guide channel, and the guide channel is connected to the inlet and corresponding to the feeding channel, the feeding part moves along the guide channel to the bottom of the inlet and continues to move along the feeding channel, thereby pushing the raw hides at the bottom of the inlet to the outlet. Other raw materials on the upper layer remain stuck in the raw material due to the restriction of the feed port side wall, the limiting rod, and the feeding part. Since the movable plate of the baffle mechanism has a baffle part 233A that is wide enough to prevent the raw materials from falling out of the discharge port, when the raw materials are pushed into the discharge port, they cannot fall out due to the obstruction of the baffle part. At this time, the first power device of the baffle mechanism drives the baffle part to move linearly, so that the baffle part opens the discharge port, so that the raw materials fall out of the discharge port under their own gravity and fall onto the conveying mechanism. Then the baffle part and the feeding part reset and repeat the above process.

[0101] This embodiment utilizes a storage structure formed by a limiting rod to temporarily store a certain amount of raw materials and maintain their vertical alignment. A feeding mechanism pushes the raw materials, which fall from the storage section to the bottom of the inlet, along the feeding channel to the outlet. A blocking mechanism then opens the outlet to allow the raw materials to fall out, achieving automatic material unloading. In this embodiment, the feeding mechanism and blocking mechanism may further include a first fixing part 220, which is fixedly mounted on the conveying mechanism. The first fixing part may also include a fixing plate and a mounting plate. The fixing plate is fixed in a preset position, and a first screw perpendicular to the surface of the fixing plate is provided. The end of the mounting plate is penetrated by the first screw, and a nut is provided on the penetrated surface of the mounting plate. The nut is threadedly engaged with the screw. The mounting plate is fixed to the unloading plate by bolts. The unloading plate is relatively fixed to the mounting plate by bolts. In this embodiment, the first power device includes, but is not limited to, a cylinder, an electric cylinder, a hydraulic cylinder, or other devices capable of driving the linear movement of the movable plate.

[0102] Example 2:

[0103] This embodiment proposes optimizations based on Embodiment 1, such as... Figure 1As shown, the processing equipment may further include a product extrusion mechanism 600, which is integrally disposed on the side of the upper sub-skin material mechanism away from the filling cutting mechanism and is fixedly installed on the conveying mechanism;

[0104] like Figure 10 As shown, the product extrusion mechanism includes:

[0105] Fourth power unit 610;

[0106] The pressure plate 640 is located above the conveying mechanism and is driven to move vertically by a fourth power device.

[0107] In this embodiment, the fourth power device includes, but is not limited to, cylinders, electric cylinders, hydraulic cylinders, or other devices capable of driving the pressure plate to move vertically. In addition, the product extrusion mechanism may also include a fourth fixing part 630, which may include a fourth threaded sleeve and a fourth threaded rod, with the fourth threaded rod and the fourth threaded sleeve threadedly engaged. The fourth power device may be fixedly installed in the second mounting part 620, the end of which is penetrated by a threaded tube. The end of the second mounting part is clamped by two sets of nuts that match the fourth threaded rod, so that the second mounting part and the fourth threaded rod remain fixed.

[0108] In this embodiment, the fourth power device drives the pressure plate to move vertically, so that the pressure plate squeezes the upper layer of dough, thereby compacting the upper and lower layers of dough and filling.

[0109] Example 3:

[0110] This embodiment proposes optimizations based on Embodiment 1, such as... Figure 11 As shown, the conveying mechanism is a chain conveyor line, such as... Figure 12 As shown, several holes 110 are formed on the surface of the chain plate in this chain conveyor line. These holes are arranged linearly and equidistantly along the length of the chain plate, such as... Figure 1 As shown, a pushing mechanism 700 and a top material mechanism 800 are sequentially provided at the discharge end of the chain conveyor line along the conveying direction. The pushing mechanism is fixedly installed above the connecting conveyor line, and the top material mechanism is set between the carrying section and the return section of the chain conveyor line.

[0111] like Figure 13 As shown, the pushing mechanism may include:

[0112] Fifth power unit 710;

[0113] Pusher 740, which is connected to the fifth power unit, and the fifth power unit drives the pusher to move linearly in the direction parallel to the conveying mechanism for conveying products;

[0114] like Figure 14As shown, the top-feeding mechanism includes:

[0115] The sixth power unit 810 is fixed to the chain conveyor line;

[0116] The material ejector section 840 is provided in multiple ways, and the multiple material ejector sections are provided with corresponding holes. The multiple material ejector sections are driven to move linearly along the axial direction of the holes by a sixth power device.

[0117] like Figure 15 As shown, when product 1100 moves to the position of the top material mechanism, the sixth power unit will drive the top material part to rise vertically. The top material part passes through the hole from bottom to top and lifts the product so that the product rises to the height of the receiving transfer line 1000. After the product is lifted to the preset height, the fifth power unit drives the pusher claw to move linearly towards the receiving conveyor line and pushes the product onto the receiving transfer line. Then the fifth power unit and the sixth power unit respectively drive the pusher claw and the top material part to retract to the initial position, and so on.

[0118] The product, conveyed to a preset position, is lifted to a preset height by an ejector mechanism, and then pushed to a higher position by a pusher mechanism, thus realizing the transfer of the product from a lower position line to a higher position line. In this embodiment, the pusher mechanism may further include a fifth fixing part 730, which may include a fifth threaded sleeve and a fifth threaded rod. The fifth threaded sleeve and the fifth threaded rod are threaded together. The fifth power device may be fixedly installed on a third mounting part 720. The end of the third mounting part is penetrated by the fifth threaded rod, and the end of the third mounting part is clamped by two sets of nuts that match the fifth threaded rod, so that the third mounting part and the fifth threaded rod are fixed. The ejector mechanism may further include a sixth fixing part 820, on which the sixth power device is fixedly installed. The sixth fixing part is fixed to the conveying mechanism. The ejector parts are all installed on sliding parts 830 and are connected to the sixth power device through the sliding parts. The fifth power device and the sixth power device include, but are not limited to, cylinders, electric cylinders, hydraulic cylinders, or other devices capable of driving linear movement of components.

[0119] For example, such as Figure 12 As shown, a plurality of limiting posts 120 are provided on the surface of the chain plate, and the plurality of limiting posts are arranged around the periphery of the hole, and the limiting posts are arranged based on the shape of the product;

[0120] The limiting post and the edge of the hole maintain a preset distance in a direction parallel to the surface of the chain plate, so as to form a support platform that contacts the lower surface of the product.

[0121] The limiting posts are arranged based on the contour of the lower surface of the product, and maintain a distance from the edge of the hole to form a support platform, thereby improving the horizontal positioning accuracy of the product.

[0122] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
