Description

Technical Field

[0001] This utility model belongs to the technical field of cross-cutting devices for condensed beads, and particularly relates to an adaptive adjustable power pressure roller cross-cutting device. Background Technology

[0002] In the field of agar pod production equipment technology, liquid, powder, and other filling contents can be independently encapsulated in a water-soluble film (e.g., PVA film) according to different design shapes. During mass production, the water-soluble film used is continuous, forming a whole product sheet after sealing. To facilitate product sales and consumer use, cross-cutting and longitudinal cutting mechanisms are typically used to cut the whole product sheet into individual agar pods.

[0003] In existing cross-cut structures, because the cutting operation separates the condensate beads from the whole product, a pressing component must be installed at the lower end of the cross-cutting blade to press the beads firmly. This is to prevent deviations in the preset cutting position due to differences in force on the film at the front and rear ends of the cross-cutting blade during the cutting process, which could lead to quality problems such as inconsistent film edge size or incorrect product cutting.

[0004] Currently, existing technologies mainly employ two methods to compress the agglomerates: chain-type cross-cutting pressure strip assemblies and non-powered pressure roller assemblies. However, both methods have significant drawbacks.

[0005] Chain-type cross-cutting strip assembly: This assembly requires custom-made cross-cutting strips in terms of quantity and arrangement to suit different pod shapes. This makes it incompatible with pod products of various shapes. When customers request a change in pod shape, the cross-cutting strip assembly must be custom-made and reinstalled. This process not only increases production costs but also significantly reduces production efficiency during product changeovers due to the time required for customization and installation. Furthermore, the chain-type cross-cutting strip has high friction with the forming roller, and this friction is hard. After prolonged use, the surface of the forming roller is easily scratched. Damaged roller surfaces directly affect the filling and sealing quality of the product, thus reducing product yield and causing economic losses to the manufacturing company.

[0006] Non-powered pressure roller assembly: When the diameter of the pressure roller in the non-powered pressure roller assembly is large, the distance between the pressing positions of the pressure rollers before and after the cross-cutting knife will increase accordingly. In this case, the condensate beads in the empty space in the middle will partially detach from the roller cavity due to insufficient pressure. This will cause the cutter to be unable to accurately cut the film, or even fail to cut the film completely, seriously affecting the cutting quality. Moreover, when the thickness of the condensate beads increases significantly, the beads may even be caught in the pressure roller, causing equipment failure and production interruption. Conversely, when the diameter of the non-powered pressure roller is small, the roller cannot effectively drive the pressure roller to rotate, increasing the friction between the pressure roller and the product, generating hard friction. This hard friction can easily scratch the film on the upper surface of the product, not only reducing product quality but also affecting production efficiency and increasing the scrap rate.

[0007] Therefore, the inventors dedicated themselves to designing a transverse cutting device to solve the above problems. Utility Model Content

[0008] The purpose of this utility model is to provide an adaptive adjustable power pressure roller cross-cutting device that can adaptively adjust, be compatible with different bead shapes, ensure cutting quality, and not damage the product or equipment.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An adaptive adjustable power pressure roller cross-cutting device includes a base, on which a blade holder is connected via a translational swing drive device. A cross-cutting blade is fixed at one end of the blade holder facing the cross-cutting opening of the base. At least one pair of power pressure rollers and at least one pair of clamping pressure rollers are provided at the cross-cutting opening of the base. The same pair of power pressure rollers are driven by external force and rotate in the same direction on the base. Both ends of each clamping pressure roller are elastically extended and limited to the base via adjusting blocks. The same pair of power pressure rollers are located between the same pair of clamping pressure rollers, and the cross-cutting blade is located between the same pair of power pressure rollers.

[0011] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, the same pair of power pressure rollers are driven to rotate in the same direction by the same belt transmission mechanism, and the surface of the power pressure rollers is coated with rubber.

[0012] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, one end of the adjusting block is rotatably sleeved on the pressing roller, the base is hinged to the opening at the other end of the adjusting block through the adjusting shaft, and the adjusting block is arranged radially along the forming roller.

[0013] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, two elongated adjustment holes are staggered on the two corresponding side walls of the opening of the adjustment block. The base is hinged to the adjustment block through two upper and lower adjustment shafts. The two adjustment shafts extend into the two adjustment holes respectively. The opening of the adjustment block is elastically connected to the base through a compression spring.

[0014] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, the translational swing drive device includes an eccentric component, a swing linkage and a slide. The slide is slidably disposed on the base, the eccentric component is rotatably disposed on the base, one end of the swing linkage is eccentrically rotatably connected to the eccentric component, and the other end of the swing linkage is hinged to the slide and elastically guided to the cutter holder.

[0015] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, one end of the swinging connecting rod is rotatably sleeved on the eccentric shaft of the eccentric component, and the knife holder is located in the opening of the other end of the swinging connecting rod.

[0016] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, the cutter holder is guided and connected to the swinging link through at least two guide posts. One end of the guide post is fixedly inserted into the cutter holder, and the part of the guide post outside the cutter holder slides through the swinging link.

[0017] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, a spring is sleeved on the guide column, and the cutter holder is elastically connected to the swinging connecting rod through the spring.

[0018] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, two guide rods are provided at intervals along the inclined direction on the inclined surface of the top of the base, and two sliding blocks at the bottom of the slide are respectively slidably sleeved on the two guide rods.

[0019] As an improvement of the adaptive adjustable power pressure roller cross-cutting device of this utility model, the base includes a slide and a base plate. The slide is slidably disposed on the base plate to adjust the distance between the slide and the forming roller. The top of the slide is inclined. All the power pressure rollers and all the pressing rollers are distributed in an arc shape to match the local shape of the forming roller.

[0020] Compared with the prior art, the adaptive adjustable power pressure roller cross-cutting device of this utility model uses a translational swing drive device to drive the blade holder and its cross-cutting blade to move horizontally and swing relative to each other to cut the granules formed on the forming roller. This avoids collision between the cross-cutting blade and the forming roller. The power pressure roller is driven by external force and rotates in the same direction so that the power pressure roller and the forming roller rotate synchronously, reducing the friction between the power pressure roller and the film on the upper surface of the product. The two ends of the clamping roller are elastically extended and limited by the base through adjusting blocks, so that the clamping roller has an adaptive adjustment function, always sticking to the surface of the forming roller, pressing the product, and compensating for the gap between the clamping roller and the forming roller. This allows it to be compatible with different granule shapes, ensure cutting quality, and not damage the product or equipment. Attached image description:

[0035] The embodiments of this utility model are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model.

[0036] Reference Figures 1 to 12 An adaptive adjustable power pressure roller cross-cutting device includes a base 1, a translational swing drive 7, and a cutter holder 61. The base 1 is connected to the cutter holder 61 via the translational swing drive 7. A cross-cutting blade 6 is fixed at one end of the cutter holder 61 facing the cross-cutting opening of the base 1. At least one pair of power pressure rollers 2 and at least one pair of pressing rollers 3 are provided at the cross-cutting opening of the base 1. The same pair of power pressure rollers 2 are driven by external force and rotate in the same direction on the base 1. The two ends of each pressing roller 3 are elastically extended and limited to the base 1 via adjusting blocks 31. The same pair of power pressure rollers 2 are located between the same pair of pressing rollers 3, and the cross-cutting blade 6 is located between the same pair of power pressure rollers 2.

[0037] Reference Figures 1 to 5The base 1 includes a slide 12 and a base plate 11. Two slide rails 111 are spaced apart on the top of the base plate 11, each slide rail 111 being arranged along the longitudinal direction (i.e., the Y-axis direction) of the base plate 11. The slide 12 is slidably mounted on the base plate 11 to adjust the distance between the slide 12 and the forming roller 8. The top of the slide 12 is inclined. Specifically, the slide 12 includes a sliding plate 123, a top plate 121, two side plates 122, and two support plates 124. The sliding plate 123 is located directly above the base plate 11. Two sliders 1231 are spaced apart on the bottom of the sliding plate 123. The sliding plate 123 connects with the forming roller 8 via the two sliders 1231 at its bottom. Two slide rails 111 are slidably connected. The top plate 121 is inclinedly set directly above the sliding plate 123 and its left and right ends are respectively fixedly connected to the sliding plate 123 through trapezoidal side plates 122. Two support plates 124 are vertically fixed on the inclined surface of the top plate 121. The two support plates 124 are spaced apart to form a transverse cut of the base 1. A locking screw 1232 is vertically inserted on the sliding plate 123. The locking screw 1232 is used to lock the sliding plate 123 to the base plate 11. The base 1 is provided with a working position and a parking position. After the contents are filled, when the film is sealed to form a whole sheet of granulated product, the transverse cutter 6 and all pressure rollers are in the working position.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11The top plate 121 is inclined at the front and lower at the back. Two guide rods 1211 are fixedly connected to the inclined surface of the top plate 121 by two pairs of fixed seats. The two guide rods 1211 are spaced apart on the inclined surface of the top of the base 1. Each guide rod 1211 is set along the width direction of the top plate 121 and in the same direction as the inclined surface of the top plate 121. The two ends of each guide rod 1211 are fixedly connected to a corresponding pair of fixed seats. The translation and swing driving device 7 includes an eccentric part 4, a swing connecting rod 5, a slide 53 and a transverse cutting motor 42. The slide 53 is U-shaped and located directly above the top plate 121. Two sliding blocks 5 are fixedly fixed at intervals at the bottom of the slide 53. 31. Two sliding blocks 531 are respectively slidably sleeved on two guide rods 1211. The slide 53 is slidably connected to the two guide rods 1211 on the top plate 121 through the two sliding blocks 531, so that the slide 53 is slidably set on the base 1. The slide 53 is located between the two support plates 124 of the base 1. The cross-cutting motor 42 is fixed on the machine base at the rear end of the top plate 121. The eccentric member 4 is set on the output shaft of the cross-cutting motor 42, so that the eccentric member 4 is rotatably set on the machine base of the base 1. The eccentric member 4 is connected to the tool holder 61 through the swinging connecting rod 5. In this embodiment, one end of the swinging connecting rod 5 is rod-shaped, and the other end of the swinging connecting rod 5 is U-shaped. One rod-shaped end is rotatably sleeved on the eccentric shaft 41 of the eccentric member 4, so that the rod-shaped end of the swinging link 5 is eccentrically rotatably connected to the eccentric member 4. The U-shaped end of the swinging link 5 is located inside the slide 53, and its left and right sides are respectively hinged to the two corresponding inner walls of the slide 53. The tool holder 61 is located in the U-shaped opening of the swinging link 5 and is elastically guided and connected to the swinging link 5. Specifically, the tool holder 61 is guided and connected to the U-shaped end of the swinging link 5 through at least two guide posts 52. One end of the guide post 52 is fixedly inserted into the tool holder 61, and the part of the guide post 52 outside the tool holder 61 slides through the U-shaped end of the swinging link 5. Each guide post 52 has A spring 51 is provided, and the blade holder 61 is elastically connected to the swing linkage 5 through the spring 51. The guide post 52 is set along the sliding direction of the slide 12 (that is, the guide post 52 is set parallel to the guide rod 1211). The eccentric part 4 moves and swings through the swing linkage 5, so that the cross-cutting blade 6 can swing relative to each other while moving horizontally. Since the cross-cutting blade 6 needs a certain depth to cut the film, it takes a certain amount of time from cutting in to cutting. However, the groove width of the cross-cutting blade 6 is limited. Conventional cylinder power can only make translational movements. The forming roller 8 and the cross-cutting blade 6 are prone to collision. The cross-cutting blade 6 structure of this utility model can move with the forming roller 8, allowing enough time for cutting. A spring 51 structure is also provided between the cross-cutting blade 6 and the swing linkage 5. Since the pressure of the cross-cutting blade 6 cutting the film is less than the force of the spring 51 compression, the cross-cutting blade 6 can work normally. When the cross-cutting blade 6 fails to cut into the blade groove due to a malfunction, the pressure at the tip of the cross-cutting blade 6 is greater than the force of the spring 51 compression. The cross-cutting motor 42 and the swing linkage 5 can still complete the remaining stroke in the reciprocating motion and return to the initial position, thus protecting the cross-cutting motor 42.

[0039] Reference Figure 4 , Figure 5 and Figure 6 The present invention preferably uses a pair of power rollers 2, which are arranged vertically at short intervals. Each power roller 2 has its two ends rotatably connected to two support plates 124 of the slide block 12. The pair of power rollers 2 are driven to rotate in the same direction by the same belt drive mechanism. This belt drive mechanism includes a roller motor 21, a driving wheel 23, two driven wheels 24, a belt 22, and a tensioning wheel 25. The roller motor 21 is fixed to a motor base at the rear end of the top plate 121. The driving wheel 23 is mounted on the output shaft of the roller motor 21. The two driven wheels 24 are respectively sleeved on the two driven wheels extending beyond the left support plate 124. In this part, the tensioning wheel 25 is rotatably mounted on the left support plate 124 and located between the driving wheel 23 and the two driven wheels 24. The belt 22 is sleeved on the driving wheel 23 and the two driven wheels 24 and its tension is controlled by the tensioning wheel 25. When the power pressure roller 2 rotates synchronously with the forming roller 8, the distance between the pair of power pressure rollers 2 is small, which prevents the product thickness from increasing. The power pressure roller 2 rotates synchronously with the forming roller 8, and the friction between the power pressure roller 2 and the film on the upper surface of the product is small. Moreover, the surface of the power pressure roller 2 is coated with rubber, so there is only soft friction between the power pressure roller 2 and the forming roller 8. This not only prevents damage to the forming roller 8, but also presses the entire product tightly, effectively preventing the pressure roller from tearing the film.

[0040] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7The preferred number of pressing rollers 3 in this invention is one pair, with the pair of pressing rollers 3 spaced vertically apart. A pair of power rollers 2 are located between the pair of pressing rollers 3. All power rollers 2 and all pressing rollers 3 are arranged in an arc shape to match the local shape of the forming roller 8. Both ends of each pressing roller 3 are elastically extended and limited by adjusting blocks 31 to the left and right support plates 124 of the base 1. Specifically, each adjusting block 31 is arranged radially along the forming roller 8. One end of the adjusting block 31 is block-shaped, and the other end is U-shaped. The block-shaped end of the adjusting block 31 is rotatably sleeved on the pressing roller 3, and the U-shaped end of the adjusting block 31 is inserted into the corresponding support plate 124. The support plate 1 of the base 1... 24 is hinged to the U-shaped opening of the adjusting block 31 by two adjusting shafts 33. Two elongated adjusting holes 34 are staggered on the two corresponding side walls of the opening of the adjusting block 31. On the same adjusting block 31, two adjusting shafts 33 (staggered left and right) on the support plate 124 extend into the two adjusting holes 34 respectively. The U-shaped opening of the adjusting block 31 is elastically connected to the support plate 124 of the base 1 by a compression spring 32. Due to the processing and installation, the forming roller 8 has a certain radial runout error. The traditional fixed pressure roller cannot compensate for the gap between it and the forming roller 8. The pressing roller 3 of this utility model is always in close contact with the surface of the forming roller 8 by the compression spring 32 inside the adjusting block 31, thus pressing the product.

[0041] The working principle of this adaptive adjustable power pressure roller cross-cutting device is as follows:

[0042] Loosen the locking screw 1232 and control the slide block 12 and the translational swing drive device 7 on it to slide together along the two slide rails 111. Adjust the distance between the slide block 12 and the forming roller 8. After the adjustment is completed, turn the locking screw 1232 to lock the slide block 12 on the base plate 11.

[0043] The forming roller 8 rotates, conveying the formed whole piece of granulated bead product to the cross-cutting device. Two pressing rollers 3 press the upper and lower ends of the area to be cut of the whole piece of granulated bead product. Each adjusting block 31 extends and retracts under the action of its compression spring 32. At the same time, the two adjusting shafts 33 slide along the two adjusting holes 34 respectively, adaptively adjusting the distance between the pressing roller 3 and the forming roller 8, thereby adjusting the pressure between the pressing roller 3 and the whole piece of granulated bead product. At this time, the pressing roller 3 can be driven to rotate by the forming roller 8.

[0044] The pressure roller motor 21 drives the drive wheel 23 to rotate, and the drive wheel 23 drives two driven wheels 24 to rotate through the belt 22, which in turn drives a pair of pressing rollers 3 to rotate, conveying the condensed bead product downwards;

[0045] The cross-cutting motor 42 drives the eccentric part 4 to rotate, which in turn drives the swing link 5, the knife holder 61 and the carriage 53 to move together along the guide rod 1211. At the same time, since the left and right sides of the swing link 5 are hinged to the carriage 53, the U-shaped end of the swing link 5 will drive the knife holder 61 and the cross-cutting knife 6 to swing relative to each other, thereby cross-cutting the part of the entire piece of condensed bead product located between a pair of power pressure rollers 2.

[0046] The adaptive adjustable power pressure roller cross-cutting device of this utility model has lower noise compared to traditional chain-type cross-cutting pressure strip assemblies or non-powered pressure roller assemblies (in existing cross-cutting structures, cylinders are commonly used to drive the transverse cutter to cut the film, and the cylinders are noisy because the transverse cutter needs to perform frequent reciprocating cutting motions); the fixed rubber-coated power pressure roller 2 and pressing pressure roller 3 compensate for the radial runout of the forming roller 8 that is unavoidable due to processing and installation errors, and prevent the product from increasing in thickness and dimensional deformation and displacement caused by elastic release. In addition, the surface of the power pressure roller 2 is rubber-coated, and the rubber-coated pressure roller only has soft friction with the forming roller 8 while pressing the product, so that the pressure roller always presses the product without damaging the forming roller 8. The forming roller 8 has a longer service life, higher stability, and improves product yield and production efficiency; while the translational swing drive device 7 is performing translational motion, the knife holder 61 and the cross-cutting knife 6 on it can swing motion, rotating with the forming roller 8, increasing the cutting time and preventing the cutter from colliding with the forming roller 8 in the cross-cutting groove.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
