Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging technology for biscuits, and in particular to a vacuum packaging device for compressed biscuits. Background Technology

[0002] Compressed biscuits are a type of convenience food made primarily from wheat flour, sugar, oil, and dairy products. The process involves mixing the flour using a cold powder process, roller baking, cooling, crushing, and external mixing. Other ingredients such as dried fruits and meat floss can be added before compression. In general, compressed biscuits are a convenient and high-energy food. After production, compressed biscuits are often vacuum-packed using a rolling vacuum packaging machine to extend their shelf life.

[0003] In existing rotary vacuum packaging machines, when vacuum packaging compressed biscuits, the packaging bags containing the compressed biscuits are placed on the conveyor belt of the packaging machine. Then, the packaging bags are sent to the bottom of the vacuum packaging box by the conveyor belt for vacuum packaging. After vacuum packaging, the vacuum-packed compressed biscuits are discharged from the conveyor belt of the packaging machine. However, when the packaging bags containing the compressed biscuits are placed on the surface of the conveyor belt, some compressed biscuit crumbs are easily adhered to the surface of the conveyor belt. These crumbs accumulate on the surface of the conveyor belt of the packaging machine and often require extra cleaning by workers. This makes vacuum packaging of compressed biscuits inconvenient. To address this, we propose a vacuum packaging device for compressed biscuits. Utility Model Content

[0004] The main objective of this invention is to provide a vacuum packaging device for compressed biscuits. A cleaning mechanism is installed at the rear panel of the vacuum packaging machine body. This cleaning mechanism forms a brushing structure at the rear panel that can contact the conveyor belt inside the vacuum packaging machine body. After the conveyor belt transports the compressed biscuit bags for vacuum packaging, the compressed biscuit crumbs on the surface of the conveyor belt can be swept off and collected by the brushes of the cleaning mechanism. This avoids the presence of compressed biscuit crumbs on the surface of the conveyor belt of the vacuum packaging machine body that require additional cleaning, ensuring that the conveyor belt and its surface clamping structure of the vacuum packaging machine body can be cleaned effectively. This can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vacuum packaging device for compressed biscuits includes a vacuum packaging machine body and a rear box plate. The rear box plate is fixed between the boxes of the vacuum packaging machine body near the discharge end of its conveyor belt. The device also includes a cleaning mechanism, which comprises a U-shaped trough, guide holes, pads, springs, pressure blocks, clamps, brush blocks, inclined guide plates, L-shaped connecting plates, round-headed vertical rods, and vertical guide seats. A U-shaped trough for chip removal is vertically opened through the rear box plate near the conveyor belt inside the vacuum packaging machine body, and a clamping mechanism is provided on the surface of the rear box plate outside the U-shaped trough for inserting the pressure block. The guide hole of the block, a pad is inserted into the guide hole below the pressure block, and the bottom spring ring of the spring is fixed on the surface of the pad. The pressure blocks are arranged and fixed on the lower plate of the clamping plate, and a brush block that abuts against the conveyor belt is glued to the plate of the clamping plate facing the conveyor belt inside the vacuum packaging machine body. An inclined guide plate is glued and fixed to the upper plate of the clamping plate, and the rear plate of the clamping plate is welded to the straight rod of the round-headed vertical rod through an L-shaped connecting plate. The round head of the round-headed vertical rod is inserted into the vertical guide groove of the vertical guide seat, and the vertical guide seat is locked to the vacuum packaging machine body on both sides of the rear box plate by bolts.

[0007] Furthermore, two sets of bottom spring coils of springs are symmetrically fixed on the surface of the pad strip, and the two sets of spring bodies abut against the lower surface of the pressure block;

[0008] By adopting the above technical solution, after the two sets of spring bodies are fixed with the pads, they can be smoothly inserted into the guide hole and subjected to pressure with the help of the pads.

[0009] Furthermore, a groove is recessed on the side of the clamping plate away from the L-shaped connecting plate, and a tail block with a brush bristle block is inserted into the groove.

[0010] By adopting the above technical solution, the clamping plate can be inserted into the tail block of the brush block for bonding and fixing using the clamping groove.

[0011] Furthermore, the inclined guide plate has a symmetrical protrusion at the bottom of the inclined plate body, and the bottom platform of the inclined guide plate is bonded to the upper plate surface of the clamping plate.

[0012] By adopting the above technical solution, the inclined guide plate is bonded and fixed to the surface of the clamping plate with its own inclined plate low base, so that the compressed biscuit package discharged from the vacuum packaging machine body can slide outward along the inclined guide plate.

[0013] Furthermore, the length of the straight rod of the round-headed vertical rod is greater than the depth of the straight groove cavity of the vertical guide groove, and the straight rod of the round-headed vertical rod protrudes from the vertical guide groove and is welded to the L-shaped connecting plate;

[0014] By adopting the above technical solution, the round-headed vertical rod can be connected to the clamping plate at the vertical guide groove by an L-shaped connecting plate to provide limiting guidance during bouncing and undulating.

[0015] Furthermore, two sets of bolts are used to lock the vertical guide seat below the vertical guide groove to the chassis of the vacuum packaging machine body;

[0016] By adopting the above technical solution, the vertical guide seat is installed on the outside of the vacuum packaging machine body by locking it with two sets of bolts.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a cleaning mechanism at the rear panel of the vacuum packaging machine body. The cleaning mechanism forms a brushing structure at the rear panel that can contact the conveyor belt inside the vacuum packaging machine body. After the conveyor belt transports the compressed biscuit bags for vacuum packaging, the compressed biscuit crumbs on the surface of the conveyor belt can be swept off and collected by the brush bristles of the cleaning mechanism, thus avoiding the presence of compressed biscuit crumbs on the surface of the conveyor belt of the vacuum packaging machine body that require additional cleaning.

[0019] Furthermore, elastic supports and guide straws are provided between the clamping plate used to hold the brush blocks and the rear box plate. When the conveyor belt and the clamping structure on the surface of the vacuum packaging machine body pass over the brush blocks, the brush blocks are pressed under the rebound support of the spring, thereby bouncing and brushing the conveyor belt and the clamping structure on the surface of the vacuum packaging machine body, ensuring that the conveyor belt and the clamping structure on the surface of the vacuum packaging machine body can be cleaned.

[0026] like Figure 1-4As shown, a vacuum packaging device for compressed biscuits includes a vacuum packaging machine body 1 and a rear box plate 2. The rear box plate 2 is fixed between the boxes of the vacuum packaging machine body 1 and the discharge end of its conveyor belt. The device also includes a cleaning mechanism 3, which includes a U-shaped trough 4, guide holes 5, pads 6, springs 7, pressure blocks 8, clamping plates 9, brush blocks 11, inclined guide plates 12, L-shaped connecting plates 13, round-headed vertical rods 14, and vertical guide seats 15. A U-shaped trough 4 for chip removal is vertically opened through the rear box plate 2 near the conveyor belt inside the vacuum packaging machine body 1, and a clamping mechanism for inserting the pressure block is also provided on the surface of the rear box plate 2 outside the U-shaped trough 4. The guide hole 5 of block 8 has a pad 6 inserted into it, and the bottom spring ring of spring 7 is fixed on the surface of the pad 6. The pressure block 8 is arranged and fixed on the lower plate surface of clamping plate 9. The plate of clamping plate 9 facing the conveyor belt inside the vacuum packaging machine body 1 has a brush block 11 that abuts against the conveyor belt. The upper plate surface of clamping plate 9 has an inclined guide plate 12 that is fixed to it. The rear plate surface of clamping plate 9 is welded to the straight rod body of round-headed vertical rod 14 through L-shaped connecting plate 13. The round head of the round-headed vertical rod 14 is inserted into the vertical guide groove 16 of vertical guide seat 15. The vertical guide seat 15 is locked to the vacuum packaging machine body 1 on both sides of the rear box plate 2 by bolts.

[0027] Among them, two sets of bottom spring rings of spring 7 are symmetrically fixed on the surface of the pad strip 6, and the two sets of spring bodies of spring 7 abut against the lower surface of the pressure block 8;

[0028] By adopting the above technical solution, after the two sets of spring bodies of spring 7 are fixed with the pad strip 6, they can be smoothly inserted into the guide hole 5 and subjected to pressure with the help of the pad strip 6.

[0029] The clamping plate 9 has a recessed groove 10 on the side away from the L-shaped connecting plate 13, and the tail block with the brush bristle block 11 is inserted into the groove 10.

[0030] By adopting the above technical solution, the clamping plate 9 can be inserted into the tail block of the brush block 11 through the clamping groove 10 for bonding and fixing.

[0031] The inclined guide plate 12 has a symmetrical protrusion at the bottom of its inclined plate body, and the bottom platform of the inclined guide plate 12 is bonded to the upper plate surface of the clamping plate 9.

[0032] By adopting the above technical solution, the inclined guide plate 12 is bonded and fixed to the surface of the clamping plate 9 with its own inclined plate low base, so that the compressed biscuit package discharged from the vacuum packaging body 1 can slide outward along the inclined guide plate 12.

[0033] Wherein, the length of the straight rod of the round-headed vertical rod 14 is greater than the depth of the straight groove cavity of the vertical guide groove 16, and the straight rod of the round-headed vertical rod 14 is exposed and welded to the L-shaped connecting plate 13.

[0034] By adopting the above technical solution, the round-headed vertical rod 14 can be connected to the clamping plate 9 at the vertical guide groove 16 via the L-shaped connecting plate 13 to provide limiting guidance during bouncing and undulating.

[0035] Among them, the vertical guide seat 15 below the vertical guide groove 16 is locked with the machine box of the vacuum packaging machine body 1 by two sets of bolts;

[0036] By adopting the above technical solution, the vertical guide seat 15 is installed on the outside of the vacuum packaging machine body 1 by locking it with two sets of bolts.

[0037] It should be noted that this utility model is a vacuum packaging device for compressed biscuits. A cleaning mechanism 3 is installed at the rear panel 2 of the vacuum packaging machine body 1. The vertical guide seat 15 of the cleaning mechanism 3 can be bolted to both sides of the vacuum packaging machine body 1 on both sides of the rear panel 2. Then, the clamping plate 9, connected by an L-shaped connecting plate 13, has its round-headed vertical rod 14 inserted into the vertical guide groove 16 of the vertical guide seat 15 for positioning and installation. At this time, the clamping plate 9 descends guided by the round-headed vertical rod 14 in the vertical guide groove 16. Next, the pad 6, with the spring 7 fixed to it, is placed into the guide hole 5 on the surface of the rear panel 2, so that the pressure block 8 below the clamping plate 9 enters the guide hole 5 and presses the spring 7. At this time, the bristles at the head of the brush block 11 can contact the conveyor belt of the vacuum packaging machine body 1 for cleaning. When the packaging bag containing compressed biscuits is placed on the clamping structure on the surface of the conveyor belt inside the vacuum packaging machine body 1... The conveyor belt can transport the packaging bag to the vacuum packaging box under the vacuum packaging machine body 1 for vacuum packaging. Then, the packaging bag is transported by the conveyor belt to the rear box plate 2 and slides down to the inclined guide plate 12 and falls outward. When the conveyor belt of the vacuum packaging machine body 1 passes the brush block 11, the bristles of the brush block 11 can brush off the compressed biscuit crumbs on the surface of the conveyor belt. When the clamping structure on the surface of the conveyor belt passes the brush block 11, it will hit the brush block 11. At this time, the brush block 11 and the clamping plate 9 are pressed down, so that the pressure block 8 presses the spring 7 to obtain elastic support and rebounds upward, thereby causing the brush block 11 to bounce and brush the conveyor belt and its surface clamping structure of the vacuum packaging machine body 1. This ensures that the compressed biscuit crumbs on the conveyor belt and its surface clamping structure can be swept and leaked downward along the U-shaped trough 4. A material box can be placed below the U-shaped trough 4 for collection.
