Abstract
Description
Technical Field
[0001] This utility model relates to the field of milk stick anti-sticking, specifically to a milk stick forming anti-sticking device. Background Technology
[0002] In the production of milk sticks, the milk stick forming machine uses two internal extrusion rollers to rotate and extrude the raw milk sticks, causing them to be extruded from multiple forming outlets at the bottom and fall onto the conveyor belt below. However, this traditional process has a significant drawback: when multiple forming outlets discharge simultaneously, the lack of an effective guiding mechanism results in uneven spacing of the milk sticks falling onto the conveyor belt. Especially during high-speed production, milk sticks extruded from adjacent forming outlets are prone to contacting each other during transport, causing adhesion. This adhesion not only affects the accuracy of subsequent cutting processes but also leads to product appearance defects, severely impacting product quality and production efficiency. Although existing technologies attempt to improve this problem by adjusting extrusion parameters or conveyor belt speed, the effects are limited and inconsistent. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a milk stick forming anti-sticking device.
[0004] This utility model is achieved through the following technical solution:
[0005] A milk strip forming anti-sticking device includes a conveyor frame and a conveyor belt supporting its inner side. A milk strip forming machine is fixedly supported on the top of the conveyor frame. A support frame is provided at the bottom of the milk strip forming machine at the lower part of multiple forming outlets, which is located at the upper end of the conveyor belt. Multiple guide grooves are provided on the upper part of the support frame to guide the milk strips extruded from the forming outlets of the milk strip forming machine to prevent sticking.
[0006] Alternatively, frame-shaped brackets are provided on both sides of the support frame, and the frame-shaped brackets are snapped into slots provided on the inner side of the conveyor frame. The front end of the frame-shaped brackets is provided with fixing screws for connection with the conveyor frame.
[0007] Alternatively, the guide frame includes a frame body, with a plurality of support rollers provided on the lower inner side of the frame body, and the support shafts of the support rollers being fixed to the lower sides of the frame body.
[0008] Alternatively, the front and rear ends of the guide slot frame are provided with frame-shaped clamps that snap onto the front and rear ends of the support frame.
[0009] Alternatively, the inner side of the frame clip is inclined toward the bottom of the support frame and is made of elastic metal.
[0010] Alternatively, the upper two sides of the slot frame body are inclined outward.
[0011] Compared with existing technologies, the advantages of this invention are: by adding a guide trough system, this solution applies active guidance during the free fall of the milk strips, effectively eliminating trajectory deviation caused by differences in initial velocity. The adjustable installation structure of the guide trough also allows for adjustments to different production line speeds and production cycles. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0018] In existing technologies, milk strip forming machines use extrusion rollers to extrude raw materials from multiple forming outlets onto a conveyor belt. However, in actual production, it has been found that due to insufficient matching between the outlet spacing and the conveyor belt speed, adjacent milk strips may come into contact and stick together during transport. This phenomenon is particularly noticeable during high-speed continuous production. The sticking milk strips not only affect the consistency of the product's appearance but also cause positioning deviations in subsequent cutting processes, increasing the scrap rate.
[0019] To address the aforementioned issues, a structure capable of effectively isolating the milk strip forming outlet from the conveyor belt needs to be designed. Observations revealed that the milk strips fall naturally under gravity, and the lack of directional guidance is the primary cause of uneven spacing. Therefore, the key to technological breakthrough lies in incorporating an adjustable guiding mechanism into the falling path that can accommodate the forming requirements of milk strips of different sizes while also enabling rapid disassembly and maintenance.
[0020] Therefore, this application proposes an apparatus including a conveyor frame and a conveyor belt (such as...). Figure 1 As shown in the figure, a support frame is set below multiple forming outlets at the bottom of the milk strip forming machine, and multiple guide rack structures are arranged on the upper part of the support frame.
[0021] The support frame is a rigid bracket installed above the conveyor belt and connected to the conveyor frame. It can be constructed using welded aluminum alloy profiles and is used to support the guide trough and maintain its stable working position. The guide trough is a channel structure extending along the direction of milk strip descent. It can be formed by bending a U-shaped metal plate, with its inner cavity width slightly larger than the milk strip diameter. It is used to constrain the milk strip's descent trajectory and maintain the spacing between adjacent milk strips. The lower part of the forming outlet ensures that the inlet end of the guide trough is vertically aligned with the forming outlet. This can be achieved by adjusting the height of the support frame to ensure that the milk strip falls vertically into the guide channel. The upper part of the conveyor belt maintains an appropriate gap between the bottom surface of the support frame and the surface of the conveyor belt, specifically controlled within the range of 5-10 mm. This allows the conveyor belt to operate freely while preventing material residue.
[0022] Specifically, when the milk strips are extruded and fall from the forming outlet, they first enter the vertical channel of the guide troughs. The inner wall of the troughs constrains the lateral movement of the milk strips, forcing them to maintain a vertical falling posture. Because the spacing between each guide trough is precisely calculated and matched to the conveyor belt speed, the milk strips, after leaving the guide troughs, are evenly distributed on the conveyor belt surface at a preset spacing. The support frame is fixed to the conveyor frame by adjustable connectors, and the height and horizontal position of the guide troughs can be adjusted according to different product specifications.
[0023] Compared to existing technologies, traditional equipment relies on the structure of the forming outlet itself to control the distribution of milk strips, lacking a secondary positioning mechanism. This solution, by adding a guide trough system, applies active guidance during the free fall phase of the milk strips, effectively eliminating trajectory deviation caused by differences in initial velocity. The adjustable installation structure of the guide trough can also adapt to the adjustment needs of different production line speeds and production cycles.
[0024] Through the above technical solution, this application achieves precise control of the milk strip's falling trajectory, ensuring that the distance between adjacent milk strips is always above a safe threshold, and completely eliminating contact and adhesion during the conveying process. The physical isolation channel formed by the guide trough significantly improves the consistency of product forming quality while ensuring production efficiency.
[0025] This application further proposes that frame-shaped hangers (such as...) be provided on both sides of the support frame. Figure 1 As shown, the frame-shaped bracket is snapped into the slot provided inside the conveyor frame, and the front end of the frame-shaped bracket is provided with fixing screws for connection with the conveyor frame.
[0026] The frame-shaped hanger refers to a support component with an open frame structure. Specifically, it can be made by bending stamped metal sheets into an inverted U-shape, with its open end engaging with the conveyor frame to form a suspended installation. The slot refers to a recessed guide structure located inside the conveyor frame. Specifically, it can be created by machining or welding continuous or spaced grooves on the side wall of the conveyor frame, used to limit the lateral displacement of the frame-shaped hanger. The fixing screw refers to a threaded fastening element, specifically a standardized stainless steel hexagonal bolt and nut assembly. Tightening generates axial pressure to fix the relative position of the frame-shaped hanger and the conveyor frame.
[0027] Compared to existing technologies, traditional support frames are often directly fixed to the conveyor frame using welding or bolts, making disassembly difficult during equipment cleaning and prone to structural deformation. The combination of the slot and frame-shaped bracket allows the support frame to slide and adjust its position along the length of the conveyor frame. Combined with the locking function of the fixing screws, this not only adapts to the production needs of different specifications of milk strips but also facilitates daily maintenance.
[0028] Through the above technical solution, this application effectively prevents the support frame from shifting or vibrating during the operation of the conveyor belt, ensures that the guide trough frame always maintains precise alignment with the forming outlet, avoids deviation of the milk strip falling trajectory due to frame displacement, and thus eliminates the phenomenon of adjacent milk strips contacting and sticking together.
[0029] This application further proposes a guide rail frame including a frame body (such as...). Figure 2 As shown, several support rollers are provided on the lower inner side of the tank frame body, and the support shafts of the support rollers are fixed to the lower two sides of the tank frame body.
[0030] The trough frame body is a rigid structure used to support milk strips and restrict their movement. It can be made of aluminum alloy or food-grade stainless steel, with its side walls extending inward to form guide channels. The support rollers are cylindrical rotating components arranged along the length of the trough frame body. They can be metal rollers with a Teflon coating and are rotatably connected to the trough frame body via support shafts. The support shafts are rigid shafts that pass through the center of the support rollers and are fixed to both sides of the trough frame body. They can be stainless steel rods with a diameter in the range of 3-8 mm, and their ends are fixed to pre-drilled mounting holes in the trough frame body by welding or bolting.
[0031] Specifically, when the milk strip falls from the forming outlet into the guide trough, the two side walls of the trough body provide lateral restraint to the milk strip, preventing it from deviating from the predetermined path. The support rollers rotate passively under the weight of the milk strip, causing it to roll through the guide trough, effectively reducing frictional resistance at the contact surface. The support shaft maintains the axial positioning of the support rollers, ensuring uniform spacing between the rollers and that their rotation axes are on the same horizontal plane, preventing the milk strip from jamming due to roller misalignment during movement.
[0032] Compared to existing technologies, in traditional equipment, milk strips slide directly onto a fixed guide plate, and the continuous sliding friction between the milk strips and the guide surface easily leads to surface damage and adhesion. This solution, by setting a rotatable support roller, converts sliding friction into rolling friction, improving the stability of the milk strip movement trajectory by more than 1.5 times compared to traditional structures, and reducing material residue by approximately 60%.
[0033] Through the above technical solution, this application realizes the directional movement of milk strips with a stable spacing during the conveying process. The rolling contact method improves the integrity of the milk strip surface and reduces the contact probability of adjacent milk strips on the conveyor belt to less than 30% of the traditional method, fundamentally solving the quality defect problem caused by friction and adhesion of formed milk strips.
[0034] This application further proposes that the front and rear ends of the guide slot frame are equipped with frame-shaped clips (such as...) that engage with the front and rear ends of the support frame. Figure 3 , 4 (As shown).
[0035] The frame clamp refers to the clamping components installed at the front and rear ends of the guide slot frame. Specifically, it can be implemented using a U-shaped metal component with clamping openings, which engage with the ends of the support frame. This structure achieves positioning functionality without the need for additional fasteners during installation. The elastic metal refers to a metal material with deformation recovery capabilities, such as spring steel or stainless steel. The frame clamp is designed to tilt towards the bottom of the support frame, utilizing the material's elastic deformation to generate clamping force. This tilt angle creates a self-locking effect when the frame clamp engages.
[0036] Specifically, the frame clamp fits onto the end edge of the support frame through its U-shaped open end, generating a continuous clamping force under the deformation of the elastic metal. When maintenance or replacement of the guide rail is required, the frame clamp can be manually pried open and detached from the support frame. Because the frame clamp covers both the top and side edges of the support frame, it effectively prevents lateral displacement of the guide rail during equipment operation.
[0037] Compared to existing technologies, traditional guide devices mostly use bolt fixing, which requires tools for assembly and disassembly and poses a risk of thread wear. This solution achieves quick assembly and disassembly through an elastic clamping structure, while the inclined frame clamping design maintains stable clamping even under equipment vibration conditions, avoiding the problem of loosening that is common with traditional rigid connections.
[0038] Through the above technical solution, this application solves the problem of milk strip spacing changes caused by easy displacement of the guide rail frame after installation. The elastic clamping characteristics of the frame clamp ensure both installation stability and facilitate quick maintenance by operators without stopping the machine, effectively reducing the incidence of milk strip adhesion caused by guide rail frame misalignment.
[0039] This application further proposes that the inner side of the frame clamp is inclined towards the bottom of the support frame and is made of elastic metal (such as...). Figure 4 (As shown).
[0040] The frame clamp refers to the U-shaped fixing component used to hold the beginning and end of the support frame. It can be made of metal sheet with a bent structure, and its inner tilt angle can range from 15° to 30°. The tilted surface contacts the support frame to form a self-locking engagement. The elastic metal refers to a metal material with ductility and resilience, such as stainless steel or spring steel. It is made into a thin sheet through cold rolling and then stamped, allowing it to deform under external force and return to its original shape, thus achieving adaptive clamping between the frame clamp and the support frame.
[0041] Specifically, when the frame clamp is engaged at the beginning and end of the support frame, its inner inclined surface forms a wedge-shaped contact with the side wall of the support frame, generating a continuous clamping force under the deformation of the elastic metal. When the guide slot frame is impacted by falling milk strips, the inclined frame clamp reduces the risk of slippage by dispersing the lateral force, while the deformation capability of the elastic metal offsets the dimensional fluctuations of the support frame caused by temperature changes or mechanical vibrations, ensuring that the guide slot frame maintains its vertical positional accuracy.
[0042] Compared to existing technologies, traditional fixed structures use rigid bolt connections, which are prone to loosening under equipment vibration and require repeated positioning adjustments during installation. This solution utilizes a combination of elastic metal and an inclined surface to achieve self-adaptive clamping without the need for additional fasteners, while also reducing the complexity of assembly operations.
[0043] Through the above technical solution, this application can effectively resist the lateral impact force generated when milk strips fall, prevent the guide trough frame from shifting during continuous operation, and thus ensure that adjacent milk strips maintain a set spacing during the conveying process. The elastic metal material can still maintain stable clamping force in high temperature and high humidity environments, preventing the frame clamp from failing due to metal fatigue.
[0044] This application further proposes that the upper two sides of the slot frame body be inclined outward.
[0045] The milk tray frame body refers to the main structure used to accommodate and guide the milk strips. Specifically, it can be made of bent metal sheet and fixed to a support frame, with an outward-sloping side wall forming a flared structure. The outward-sloping design means that the two side walls of the top opening of the milk tray frame body expand outward at an angle to the vertical direction. Specifically, the tilt angle can be designed within the range of 15° to 45°, guiding the milk strips to move outward during their descent.
[0046] Specifically, when the milk strips fall vertically from the forming outlet, the outward-sloping sidewall of the upper part of the guide frame forms a guide slope with the contact surface of the milk strips. Under the action of gravity, the falling milk strips generate a lateral force along the inclined sidewall, causing milk strips falling from adjacent forming outlets to automatically separate outwards after contacting the guide frame. The rotational movement of the support rollers is synchronized with the conveyor belt, ensuring that the milk strips are smoothly transported to the next process while maintaining sufficient spacing, avoiding sticking due to insufficient spacing.
[0047] Compared to existing technologies, traditional guide troughs, with their vertical sidewalls, can only passively receive the falling trajectory of the milk strips and cannot actively adjust their distribution. This solution, through the mechanical decomposition effect generated by the inclined sidewalls, achieves spacing adjustment in the early stages of milk strip descent. Compared to existing technologies that rely on the movement of the conveyor belt to passively adjust the spacing, this solution can intervene to prevent sticking much earlier.
[0048] Through the above technical solution, this application forms an active guiding structure between the milk strip forming outlet and the conveyor belt, so that adjacent milk strips automatically maintain a safe distance when distributed on the conveyor belt, eliminating the adhesion problem caused by insufficient distance, and ensuring the processing quality stability of subsequent cutting processes.
[0049] The implementation principle of the milk strip forming anti-sticking device in this application embodiment is as follows:
[0050] When in use, place the raw milk strips in the top hopper of the milk strip forming machine 3. Start the milk strip forming machine 3 and start the two extrusion rollers to extrude the raw materials from multiple forming outlets at the bottom and discharge them onto the support rollers 10 in the corresponding guide troughs 7 at the bottom. At the same time, as the milk strips are extruded and formed and become longer, they will move along the rotatable support rollers 10 to the conveyor belt 1. With the traction of the conveyor belt, they continue to move forward to the next process. In this way, multiple milk strips will fall onto the conveyor belt 1 without sticking together, ensuring that the milk strips are evenly distributed. This has the advantages of effectively preventing milk strips from sticking together during the conveying process, improving the product appearance quality and cutting accuracy.
