Description

Technical Field

[0002] Cheese is a fermented milk product with a high nutritional value among dairy products. Existing cheese products are mostly packed in packaging shells of various shapes, which not only ensures food safety, but also arouses customers' desire to buy.

[0003] The existing processing process of cheese with packaging shell is as follows: (1) pouring molten milk into a packaging shell of a specific shape; (2) sealing the packaging shell; (3) cooling and shaping; (4) cutting the packaging shell at a cutting device to form a single product. Cooling and shaping is one of the most important links in the processing process. Cooling and shaping is mainly completed by transferring the cheese to the cooling tunnel by the transmission device. The transmission device has a specific transmission path, so that the temperature of the cheese with packaging shell can be reduced from 75°C to 20°C during the transmission process of the transmission device, thereby completing the cooling and shaping.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0048] like Figure 1-Figure 7As shown, the product transmission device disclosed in the embodiment of the present invention includes a frame 1, a conveying assembly, a driving assembly 7 and a clamping assembly 8, and the conveying assembly, the driving assembly 7 and the clamping assembly 8 are all arranged on the frame 1. The frame 1 plays a supporting and fixing role. Exemplarily, the conveying assembly includes a guide rail 2, and the guide rail 2 is arranged on the frame 1. The product can be transmitted along the guide rail 2 to achieve orderly product transmission. The driving assembly 7 includes a driving wheel 71 and a driven wheel 72 rotatably mounted on the frame 1. The driving wheel 71 and the driven wheel 72 are relatively arranged on both sides of the guide rail 2, and the product can be clamped between the driving wheel 71 and the driven wheel 72, and the product can be driven to be transmitted along the guide rail 2 by rotation, so as to achieve automatic and stable transmission of the product. And the first rotating shaft 73 of the driven wheel 72 is movably mounted on the frame 1 through the first rolling bearing 74 to adjust the spacing between the driving wheel 71 and the driven wheel 72, so that the spacing can be adaptively and automatically adjusted according to the size change of the product surface, avoiding the phenomenon of the product surface becoming stuck due to the increase in size. The clamping assembly 8 includes a clamping block and an elastic member, wherein the clamping block is movably mounted on the frame 1; the elastic member is compressed and arranged between the clamping block and the frame 1 so that the clamping block and the side of the first rolling bearing 74 facing away from the driving wheel 71 are kept in contact with each other, so as to achieve adjustment of the spacing between the driving wheel 71 and the driven wheel 72 while ensuring that the driving wheel 71 and the driven wheel 72 are always clamped with the product surface, thereby improving transmission stability.

[0049] Optionally, the frame 1 is made of stainless steel and has a rectangular frame structure. It mainly supports and fixes the conveying assembly, the driving assembly 7 and the pressing assembly 8. The frame 1 is provided with a first mounting groove 11 and a second mounting groove 12 to facilitate the installation of the driving assembly 7. Furthermore, the second mounting groove 12 is a long strip groove and the length direction of the second mounting groove 12 is perpendicular to the transmission direction of the product.

[0050] Optionally, the guide rail 2 includes a first guide rail 21 and a second guide rail 22 arranged in parallel, and the first guide rail 21 and the second guide rail 22 cooperate to clamp the product for transmission.

[0051] Exemplarily, the first guide rail 21 is connected and fixed to the frame 1. The cross section of the first guide rail 21 is "T" shaped, and a first guide groove is provided thereon, and the bottom of the product is located in the first guide groove.

[0052] Correspondingly, the second guide rail 22 is arranged parallel to the first guide rail 21, and the second guide rail 22 is connected and fixed to the frame 1. The cross section of the second guide rail 22 is also "T" shaped, and a second guide groove is arranged on it, and the top of the product is located in the second guide groove. The second guide groove cooperates with the first guide groove to form a transmission track for the product.

[0053] Alternatively, if Figure 2 and Figure 3As shown, when the product is transported, there is a large sliding friction between the bottom of the product and the first guide rail 21, which not only reduces the transmission efficiency but also causes wear on the product. Therefore, the product transmission device also includes a first friction reduction assembly 3, which includes a first connecting block 31 and a first bearing 32. The first connecting block 31 is fixed on the frame 1, and the first bearing 32 is rotatably mounted on the first connecting block 31.

[0054] like Figure 3 As shown, exemplarily, a first through slot 311 is provided on the first connecting block 31, and both ends of the first through slot 311 are respectively connected to the first guide slot of the first guide rail 21 and the bottom surface of the first through slot 311 is flush with the bottom surface of the first guide slot. A first clamping slot is provided along a direction perpendicular to the length of the first through slot 311, and the length of the first clamping slot is greater than or equal to the width of the first through slot 311. In this embodiment, the cross-sectional area of ​​the first friction reducing assembly 3 is "U" shaped, and its U-shaped bottom surface is fixed on the frame 1, and its U-shaped top surface is provided with two first connecting blocks 31 opposite to each other, which are respectively provided at the bottom of the two first guide rails 21, so as to simultaneously reduce the sliding friction of the two adjacent first guide rails 21.

[0055] The first bearing 32 is rotatably clamped in the first clamping groove. The rolling surface of the first bearing 32 is used to bear the bottom of the product, and the highest point of the rolling surface of the first bearing 32 is higher than the bottom surface of the first guide groove of the first guide rail 21. During transmission, when the product passes through the first through groove 311, the bottom of the product is placed on the rolling surface of the first bearing 32, so that the bottom of the product is at least partially separated from the bottom surface of the first guide groove, so that the contact between the product and the first guide groove is reduced. When the product is transmitted forward, it drives the first bearing 32 to rotate, thereby converting the original sliding friction between the product and the first guide rail 21 into rolling friction with the first bearing 32, greatly reducing friction, improving transmission efficiency and reducing product wear. Optionally, a plurality of first friction reduction components 3 can be arranged at intervals along the length direction of the first guide rail 21, so as to minimize the sliding contact between the bottom of the product and the first guide rail 21, so that it can achieve rolling friction with the first bearing 32, and reduce product friction.

[0056] It is understandable that if Figure 1 As shown, a second friction reduction assembly 4 can also be provided to reduce the sliding friction between the product and the second guide rail 22. Its specific configuration is similar to the first friction reduction assembly 3, except that the rolling surface of the second bearing is used to receive the top of the product, and the lowest point of the rolling surface of the second bearing is lower than the bottom surface of the second guide groove of the second guide rail 22 so that the top of the product can contact the rolling surface of the second bearing, thereby reducing the direct contact between the product and the bottom surface of the second guide groove. When the product is transmitted, the second bearing is driven to rotate, thereby further converting the sliding friction into rolling friction, reducing the friction, and improving the transmission efficiency.

[0057] Through the cooperation of the first anti-friction component 3 and the second anti-friction component 4, the sliding friction between the bottom of the product and the first guide rail 21, and the sliding friction between the top of the product and the second guide rail 22 can be converted into rolling friction, thereby reducing the wear of the guide rail 2 on the product during the transmission process and improving the transmission efficiency. In this embodiment, during transmission, the self-weight of the product almost entirely acts on the first guide rail 21, and the second guide rail 22 only acts on a small part of the limiting force to prevent the product from escaping from the guide rail 2. Therefore, in this embodiment, a plurality of first anti-friction components 3 are only arranged along the length direction of the first guide rail 21, and the arrangement of the second anti-friction component 4 is omitted, so as to achieve the purpose of reducing friction. In other embodiments, the first anti-friction component 3 and the second anti-friction component 4 can also be arranged at the same time, which is not limited to this embodiment.

[0058] Optionally, the guide rail 2 can be provided with a plurality of guide rails 2 as a channel for conveying the product, and the plurality of guide rails 2 are connected in sequence to extend the conveying path of the product, so as to ensure that the product can be cooled to a preset value to achieve shaping. In actual use, the number of guide rails 2 can be set according to actual needs, with the ability to cool the product to a preset temperature as a benchmark.

[0059] like Figure 1 As shown, further, in order to realize the connection and fixation of two adjacent guide rails 2, the rack 1 also includes an intermediate adapter frame 5, and the two sides of the intermediate adapter frame 5 are fixedly connected to one guide rail 2. Optionally, the intermediate adapter frame 5 is detachably connected to the guide rail 2 to facilitate the disassembly and maintenance of the equipment. It can be understood that the intermediate adapter frame 5 not only connects and fixes the two adjacent guide rails 2, but also ensures the rigidity required by the guide rail 2.

[0060] Preferably, in order to realize smooth transmission of the product at the intermediate transfer frame 5, a first anti-friction assembly 3 and a second anti-friction assembly 4 are correspondingly provided along the height direction of the intermediate transfer frame 5, two adjacent first guide rails 21 are connected through the first anti-friction assembly 3, and two adjacent second guide rails 22 are connected through the second anti-friction assembly 4. The first anti-friction assembly 3 and the second anti-friction assembly 4 simultaneously adopt rolling transmission for the top and bottom ends of the product, thereby reducing the sliding friction resistance of transmission and improving the smoothness of the product passing through the intermediate transfer frame 5.

[0061] In actual operation, the product transmission equipment operates in a certain area, and the length of the area may not meet the required length of the guide rail 2. Therefore, a guide component 6 can be further provided to turn the guide rail 2, which can extend the product transmission path without occupying too long an operating area.

[0062] like Figure 1 , Figure 2 and Figure 4As shown, illustratively, the guide assembly 6 includes a first arc-shaped guide groove 61 and a second arc-shaped guide groove which are relatively arranged on the frame 1, and the two ends of the first arc-shaped guide groove 61 are respectively connected to the two adjacent first guide rails 21. The two ends of the second arc-shaped guide groove are respectively connected to the two adjacent second guide rails 22, and the second arc-shaped guide groove and the first arc-shaped guide groove 61 cooperate to form a guide track, and the guide track is configured to guide the product to achieve smooth turning between the two adjacent guide rails 2. In this embodiment, the guide rail 2 mainly performs 90° and 180° reversing. When the guide rail 2 performs 90° reversing, the guide track is set to a quarter arc; when the guide rail 2 performs 180° reversing, that is, when the product performs reversing on two adjacent parallel guide rails 2, the guide track includes at least half an arc.

[0063] In this embodiment, the guide rails 2 located at the outermost side of the rectangular frame 1 are reversed by 90° through the guide assembly 6. The guide rails 2 located inside the rectangular frame 1 and arranged in parallel are provided with a guide assembly 6 at both ends of the frame 1, and each two adjacent guide rails 2 are reversed by 180° to form multiple continuous "S"-shaped transmission paths, extending the product transmission path and duration. A guide rail 2 located at the end of the product transmission equipment is connected to the next process link to output the product after cooling and finalization. In actual application, the number of guide rails 2 and the reversing angle can be set as needed, so as to reduce the temperature of the product to a preset temperature, which is not limited to this embodiment.

[0064] like Figure 4 As shown, further, in order to reduce the friction between the product and the guide track. The above-mentioned guide assembly 6 also includes a third bearing 611, which is rotatably arranged on a side wall of the first arc-shaped guide groove 61 that is pressed by the product. And the axis of the third bearing 611 is perpendicular to the plane where the first arc-shaped guide groove 61 is located. There is a first gap for the product to pass between the third bearing 611 and the side of the first arc-shaped guide groove 61 where the third bearing 611 is not arranged, and the rolling surface of the product and the third bearing 611 are in close contact. According to this arrangement, in the process of the product moving along the guide track, the product drives the third bearing 611 to rotate, thereby converting the sliding friction between the product and the side wall of the first arc-shaped guide groove 61 into rotational friction, greatly reducing the friction, so that the product can achieve smooth turning. A plurality of third bearings 611 are arranged at intervals along the first arc-shaped guide groove 61 to minimize the sliding friction between the product and the first arc-shaped guide groove 61.

[0065] Accordingly, in order to further reduce the friction between the product and the guide track, a plurality of third bearings 611 are also arranged at intervals in the second arc-shaped guide groove. The arrangement of the third bearings 611 is the same as that in the first arc-shaped guide groove 61, and will not be repeated here.

[0066] By arranging a plurality of third bearings 611 at intervals in the first arc-shaped guide groove 61 and the second arc-shaped guide groove, the product rolls in contact with the third bearings 611 when passing through the guide track, thereby greatly reducing the switching friction resistance of the product and achieving smooth turning of the product.

[0067] like Figure 1 and Figure 5 As shown, optionally, in order to realize the installation of the driving wheel 71. The above-mentioned driving assembly 7 also includes a second rotating shaft 75 and a second rolling bearing 76, the driving wheel 71 is fixedly sleeved on the outer periphery of the second rotating shaft 75, and a second rolling bearing 76 is connected to each end of the second rotating shaft 75, and the driving wheel 71 is located between the two second rolling bearings 76. The second rolling bearing 76 is installed in the first installation groove 11 to realize the installation and fixation of the driving wheel 71. One end of the second rotating shaft 75 is connected to the driving motor. According to this setting, the driving motor drives the second rotating shaft 75 to rotate, thereby driving the rotation of the driving wheel 71, and the driving wheel 71 drives the product to be automatically transmitted along the guide rail 2. In this embodiment, two driving wheels 71 are provided, and the two driving wheels 71 are relatively arranged at the upper and lower ends of the second rotating shaft 75 to clamp and transmit the upper and lower sides of the product to improve the transmission stability. In other embodiments, a corresponding number of driving wheels 71 can be set according to the size of the product to make the transmission stable, and no specific restrictions are made here.

[0068] Correspondingly, the driven wheel 72 is fixedly sleeved on the outer periphery of the first rotating shaft 73, and a first rolling bearing 74 is connected to each end of the first rotating shaft 73, and the driven wheel 72 is located between the two first rolling bearings 74. The first rolling bearing 74 is arranged in the second mounting groove 12 and the first rolling bearing 74 can move along the length direction of the second mounting groove 12. According to this arrangement, a gap for the product to pass through is formed between the driven wheel 72 and the driving wheel 71, and the gap is located on the same plane as the guide rail 2 and the width of the gap is smaller than the thickness of the product to clamp the product, and the driven wheel 72 can be driven to rotate by the product. The cooperation between the driving wheel 71 and the driven wheel 72 realizes the automatic and stable forward transmission of the product. Correspondingly, in this embodiment, two driven wheels 72 are also provided, and the positions of the two driven wheels 72 correspond to the positions of the two driving wheels 71, so as to clamp and transmit the product up and down, thereby improving the transmission stability.

[0069] In this embodiment, the driving wheel 71 is used as the main power source, and the driven wheel 72 is used as the driven power to assist in clamping the product so as to realize the transportation of the product along the guide rail 2, thereby ensuring the consistency of the rotation speeds of the driving wheel 71 and the driven wheel 72 and improving the transmission stability. Of course, in other embodiments, the driven wheel 72 can also be connected to the driving motor as the second main power source. In this case, the driven wheel 72 and the driving wheel 71 have the same rotation speed and opposite rotation directions so that the two can cooperate to transport the product.

[0070] In this embodiment, since the product requires a large transmission force when the guide rail is reversed, in order to ensure that the product has sufficient transmission power when it is reversed, a driving assembly 7 is provided at the transmission entrance and the transmission exit of each guide assembly 6 to realize product transmission. Optionally, in this embodiment, a driving wheel 71 is matched with a driven wheel 72 on both sides to provide transmission power to two adjacent parallel guide rails 2 at the same time, thereby improving transmission stability.

[0071] Alternatively, if Figure 6 and Figure 7 As shown, the pressing block includes a first pressing block 81 and a second pressing block 82. One end of the first pressing block 81 presses against the first rolling bearing 74, and the other end of the first pressing block 81 is set as a first inclined surface 811. The second pressing block 82 is provided with a second inclined surface 821 abutting against the first inclined surface 811, and a limiting hole 822 is vertically provided on the second pressing block 82.

[0072] Exemplarily, the first clamping block 81 is installed in the second mounting groove 12 and can move back and forth along the length direction of the second mounting groove 12. An arcuate surface is provided at one end of the first clamping block 81, through which the first clamping block 81 presses against the edge of the first rolling bearing 74. The first inclined surface 811 is provided on the side of the first clamping block 81 away from the arcuate surface.

[0073] Correspondingly, the second pressing block 82 is also installed in the second installation groove 12 , and one end of the second pressing block 82 away from the second inclined surface 821 abuts against the frame 1 .

[0074] Further, the elastic member includes a positioning screw and a spring. One end of the positioning screw passes through the limiting hole 822 and is fixedly connected to the frame 1, and the second clamping block 82 can move back and forth along the positioning screw. The spring is sleeved on the outer periphery of the positioning screw, and one end of the spring is fixed in the limiting hole 822, and the other end of the spring extends out of the limiting hole 822 and abuts against the nut of the positioning screw, or the other end of the spring extends out of the limiting hole 822 and abuts against one side of the positioning screw connected to the frame 1. With this arrangement, when the thickness of the product increases, the product squeezes the first rolling bearing 74 to move along the second mounting groove 12, so that the first clamping block 81 moves toward the second clamping block 82, and the second clamping block 82 is forced to move along the positioning screw to increase the spacing between the driving wheel 71 and the driven wheel 72. When the thickness of the product decreases, the second clamping block 82 pushes the first clamping block 81 to move toward the first rolling bearing 74 under the reset force of the spring, so that the driven wheel 72 approaches the driving wheel 71 to reduce the spacing and maintain the clamping of the product. The arrangement of the clamping assembly 8 can ensure that the driving wheel 71 and the driven wheel 72 are always clamped to the surface of the product while achieving the adjustment of the distance between the driving wheel 71 and the driven wheel 72.

[0075] Alternatively, if Figure 7As shown, when the first inclined surface 811 abuts against the upper side of the second inclined surface 821, one end of the spring is fixed in the limiting hole 822, and the other end of the spring abuts against one side of the positioning screw connected to the frame 1. When the surface thickness of the product changes from thin to thick, when the product passes through the gap between the driving wheel 71 and the driven wheel 72, the product squeezes the first rolling bearing 74, pushing the first clamping block 81 to move toward the second clamping block 82, and the first inclined surface 811 exerts a downward thrust on the second inclined surface 821, generating a downward thrust on the second clamping block 82, causing the second clamping block 82 to move downward, thereby increasing the spacing to facilitate the passage of the product. When the surface thickness of the product changes from thick to thin, when the product passes through the gap between the driving wheel 71 and the driven wheel 72, the force on one side of the driven wheel 72 is relatively reduced, that is, the force of the first clamping block 81 on the second clamping block 82 is reduced, and the second clamping block 82 moves upward due to the restoring force of the spring, thereby pushing the first clamping block 81 to move in the direction close to the driven wheel 72, so that the gap between the driving wheel 71 and the driven wheel 72 is reduced, and the clamping transmission of the product is maintained.

[0076] Optionally, when the first inclined surface 811 abuts against the lower side of the second inclined surface 821, one end of the spring is fixed in the limiting hole 822, and the other end of the spring extends out of the limiting hole 822 to abut against the nut of the positioning screw. According to this arrangement, when the surface thickness of the product changes from thin to thick, when the product passes through the gap between the driving wheel 71 and the driven wheel 72, the product squeezes the first rolling bearing 74 to push the first clamping block 81 toward the second clamping block 82. The first inclined surface 811 exerts an upward thrust on the second inclined surface 821, which generates an upward thrust on the second clamping block 82, causing it to move upward, thereby increasing the gap to facilitate the passage of the product and prevent the product from getting stuck. When the surface thickness of the product changes from thick to thin, when the product passes through the gap between the driving wheel 71 and the driven wheel 72, the force on one side of the driven wheel 72 is relatively reduced, that is, the force of the first clamping block 81 on the second clamping block 82 is reduced, and the second clamping block 82 moves downward by the restoring force of the spring, thereby pushing the first clamping block 81 to move in the direction close to the driven wheel 72, so that the gap between the driving wheel 71 and the driven wheel 72 is reduced, thereby maintaining the clamping transmission of the product.

[0077] It is understandable that in the initial state after installation, the spring is in a compressed state so that the second clamping block 82 has an elastic pressing force on the first clamping block 81, so that there is a clamping force between the driving wheel 71 and the driven wheel 72 to ensure the transmission stability of the product. There is also a spacing between the bottom of the second clamping block 82 and the frame 1 or between the top of the second clamping block 82 and the nut so that the gap between the driving wheel 71 and the driven wheel 72 can be adaptively adjusted by moving the second clamping block 82 up and down along the positioning screw, so that it can be adaptively adjusted automatically according to the size changes of the product surface, which not only ensures the stable transmission of the product, but also avoids the situation where the product is stuck. It should be noted that since the size of the gap between the driving wheel 71 and the driven wheel 72 is fine-tuned, the size of the gap can be adaptively adjusted by moving the second clamping block 82 along the positioning screw and the first clamping block 81 in the second installation groove 12, which is very convenient.

[0078] In this embodiment, a clamping assembly 8 is provided at each first rolling bearing 74 to simultaneously clamp both ends of the first rotating shaft 73, thereby achieving synchronous clamping of the upper and lower ends of the product and enhancing the stability and reliability of the clamping.

[0079] Therefore, a product transmission device provided by an embodiment of the present invention, by setting a conveying component, the conveying component includes a guide rail 2, and the products are transported in order along the guide rail 2 to avoid disordered stacking of the products, which is beneficial to the heat dissipation and cooling of the products; a driving wheel 71 and a driven wheel 72 are further provided to clamp and drive the products, so as to realize automatic and stable transmission of the products; further, through the movable design of the driven wheel 72, the distance between the driving wheel 71 and the driven wheel 72 can be adaptively and automatically adjusted according to the size change of the product surface, thereby avoiding the phenomenon of the product surface becoming stuck due to the increase in size; by setting a clamping component 8, the clamping component 8 includes a clamping block and an elastic member, the clamping block is movably installed on the frame 1, and the elastic member is compressed and arranged between the clamping block and the frame 1, so that the clamping block and the side of the first rolling bearing 74 facing away from the driving wheel 71 are kept in contact with each other. While the spacing between the driving wheel 71 and the driven wheel 72 can be automatically adjusted, it can ensure that the driving wheel 71 and the driven wheel 72 are always clamped on the product surface, so that the product can be transmitted forward stably and continuously, and the product is prevented from being damaged due to excessive force and transmission jamming.

[0080] A first friction reducing assembly 3 is further provided on the first guide rail 21 to convert the sliding friction between the product and the first guide rail 21 into rolling friction with the first bearing 32, thereby greatly reducing the friction resistance of transmission and improving the transmission efficiency.

[0081] A guide assembly 6 is further provided, and the guide assembly 6 includes a first arcuate guide groove 61 and a second arcuate guide groove which are relatively arranged on the frame 1, and the two ends of the first arcuate guide groove 61 are respectively connected to the two adjacent first guide rails 21, and the two ends of the second arcuate guide groove are respectively connected to the two adjacent second guide rails 22, and the second arcuate guide groove and the first arcuate guide groove 61 cooperate to form a guide track to guide the product to achieve smooth turning between the two adjacent guide rails 2.

[0082] A plurality of third bearings 611 are provided at intervals inside at least one of the first arc-shaped guide groove 61 and the second arc-shaped guide groove to reduce the friction resistance of the product reversal, so that the reversal can be completed smoothly and the wear on the product can be reduced.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
