Description

Technical Field

[0001] The invention relates to the technical field of cigarette sheet glue production, and in particular to a cylindrical gel cutting device capable of realizing continuous discharging. Background Art

[0002] For the processing of natural rubber latex blocks after coagulation, the traditional cutting method is mainly through manual cutting. This cutting method is not only inefficient and labor-intensive, but also difficult to ensure the cutting accuracy and consistency. It is easy to have problems such as uneven slicing and different thicknesses. In addition, due to the instability of manual operation, it is also easy to cause safety problems during the cutting process.

[0003] At present, there are also attempts to cut the rubber block in a mechanized manner, mainly using a blade to cut the raw rubber block placed on the table from top to bottom, such as a rubber slicing device disclosed in CN220030330U, which is mainly for strip gel, and cannot be cut into continuous slices. A highly efficient rubber slicing device is disclosed in CN110181589A, which realizes the cutting of cylindrical gel, and after cutting, it is continuous slices, which is also convenient for subsequent tableting. However, due to the need to add acid to solidify when rubber latex prepares cylindrical gel, before slicing, it is necessary to wash the residual acid with water, and the slicing device in CN110181589A adopts the mode of cutting at the bottom, and it is necessary to rely on the downward thrust of the compression spring and the gravity of the rubber embryo itself to ensure that the rubber embryo and the pressing roller always keep fitting and conflicting, thereby ensuring the cutting thickness, but due to the influence of buoyancy in water on the cylindrical gel, the device cannot realize cutting the cylindrical gel in water, and also cannot realize the synchronous carrying out of acid washing and continuous slicing.

[0004] Based on this, an automated gel slice rotary cutting device is needed to achieve continuous acid washing and slicing. Summary of the invention

[0005] In view of the above problems, the present invention provides a cylindrical gel cutting device capable of achieving continuous discharging, which realizes automatic continuous slicing of cylindrical gel, greatly improves production efficiency and ensures slicing quality.

[0025] The clamping unit is arranged at the discharge of the rotary cutting mechanism, and is used to clamp the sheet head formed by cutting the cylindrical gel; the clamping unit is configured to move from the discharge of the rotary cutting mechanism to the downstream feed of the pressing roller; when the discharge detection sensor detects the sheet head, the clamping unit is actuated to clamp the sheet head and drive it to move to the feed of the pressing roller;

[0026] A material break detection sensor is provided at the feeding position of the pressing roller to detect whether the material is broken. When the material break detection sensor detects that the material is broken, the pressing roller stops running and waits for the overlap to be completed. The material break detection sensor is also used for the sheet head clamped and delivered by the clamping unit;

[0027] The crimping unit is arranged on the side of the material break detection sensor close to the pressure roller;

[0028] When the material break detection sensor detects the head of the sheet, the clamping unit releases the head of the sheet, and the head of the sheet falls naturally and overlaps with the tail of the previous sheet. The crimping unit operates to squeeze the overlapping part so that the two sheets are overlapped together.

[0029] Furthermore, the peeling mechanism is connected to a downwardly inclined blanking plate at the discharge end, and a second buffer pool is provided at the discharge end of the blanking plate, in which a cleaning solution is provided;

[0030] The clamping unit is located at the discharge end of the blanking plate. When the clamping unit drives the sheet head to move, the sheet is immersed in the cleaning solution.

[0039] Furthermore, a pattern is provided on the surface of the belt roller, and the direction of the pattern is toward the moving direction of the rotary cutter of the rotary cutting mechanism.

[0040] Working principle of the present invention:

[0041] After the cylindrical gel 9 is sent into the first buffer pool 2 (the gel 9 is suspended on the water due to buoyancy), the cylindrical gel is manually fixed by the mandrel 31 and placed on the circular feed chain 3. The rotary cutting mechanism 1 transmits power to the circular feed chain 3 through the transmission component, driving the gel 9 to move forward with the mandrel 31. When the cylindrical gel 9 contacts the belt roller 4 at the rear end, the gel 9 rotates around the mandrel 31 under the friction of the belt roller 4. At the same time, the rotary cutter of the rotary cutting mechanism 1 cuts the rotating gel 9. While cutting, the gel 9 continues to feed along the circular feed chain 3, thereby realizing continuous slicing of the cylindrical gel 9, and the gel 9 can be cut from a cylindrical shape into a sheet. The cutting speed of the rotary cutter matches the feeding speed of the gel 9 to ensure uniform slice thickness. The slice thickness is adjusted by the feeding speed (20±5mm), and the sliced ​​film is transported from the discharge end to the next process. After completing the peeling of one roll of gel 9, the peeling of the next gel 9 begins immediately. At the same time, the core shaft 31 circulates back to the initial position along the circular feed chain 3, and the gel 9 is manually inserted on the core shaft 31 and re-fixed on the circular feed chain 3, and the aforementioned feeding action cycle is continued for peeling.

[0042] After the sheet cut from the cylindrical gel 9 is thrown out from the discharge end of the rotary cutting mechanism 1, it is detected by the discharge detection sensor 81 above, and the clamping unit 82 is actuated to clamp the head of the sheet 91. At the same time, the discharge end of the rotary cutting mechanism 1 continues to discharge. When the clamping unit 82 moves forward to the feeding position of the pressing roller 7 and reaches the crimping station, the clamping unit 82 opens and keeps moving. At this time, the head of the sheet 91 naturally falls down and overlaps with the tail of the previous sheet 91. Then the crimping unit 83 presses down the overlapping part to overlap the two sheets together, thereby forming a continuous sheet. After the crimping unit 93 is reset, the downstream pressing roller 7 starts, drives the sheet 91 to move, and realizes the sheeting process.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] (1) The cylindrical gel cutting device capable of continuous discharging provided by the present invention realizes automatic feeding and automatic cutting of gel, which can effectively improve production efficiency.

[0045] (2) The cylindrical gel is cached in the first buffer pool, and the cylindrical gel can be acid-washed and provided with buoyancy to facilitate the operation of passing the core shaft.

[0046] (3) The device transmits the power of the rotary cutting mechanism to the circular feed chain through the transmission assembly, driving the gel feed. The cutting speed of the rotary cutter matches the gel feed speed, and the gel rotates under the friction of the belt roller, ensuring uniform slice thickness and avoiding the problem of slice quality degradation due to changes in the tool position.

[0047] (4) A lap joint mechanism is arranged downstream of the rotary cutting mechanism to connect the front and rear sheets, so that the sheets are formed into uninterrupted and continuous sheets, so that the downstream cutting process can obtain films of consistent length, thus ensuring that the external dimensions of the final product are uniform.

DETAILED DESCRIPTION

[0063] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0064] Example 1

[0065] like Figure 1 As shown, a cylindrical gel cutting device capable of realizing continuous discharge includes a feeding rotary cutting section and an overlapping section. The feeding rotary cutting section includes a feeding mechanism, a rotary cutting mechanism 1, a first buffer pool 2 and a belt roller 4. The first buffer pool 2 is located at the feeding side of the rotary cutting mechanism 1 and contains water. After the cylindrical gel 9 is fed into the first buffer pool 2, the gel 9 is suspended on the water by the buoyancy, which is convenient for the movement of the gel 9 and the subsequent installation of the mandrel 31. At the same time, the water in the first buffer pool 2 will wash the acid on the surface of the gel, achieving the purpose of acid washing. The belt roller 4 is located above the rotary cutting mechanism 1. The feeding mechanism delivers the gel 9 to the belt roller 4 and the rotary cutting mechanism 1. The gel 9 contacts the belt roller 4. The belt roller 4 rotates to drive the gel 9 to rotate around the mandrel 31. At the same time, the rotary cutter of the rotary cutting mechanism 1 cuts the rotating gel 9. The gel 9 continues to feed while cutting, thereby realizing continuous slicing of the cylindrical gel 9. The overlapping section is located downstream of the feeding peeling section, specifically at the discharge end of the peeling mechanism 1, which includes a second buffer pool 5 and an overlapping mechanism. The second buffer pool 5 stores water, and its end is connected to the downstream pressing roller 7. It is mainly used for acid washing of the sheets formed by peeling, as well as for caching the sheets and providing buoyancy to facilitate the overlapping and transportation of the front and rear sheets, and to form a continuous film after being pressed by the pressing roller 7.

[0066] Specifically, Figure 2-3As shown, the feeding mechanism includes: an annular feeding chain 3 and a transmission assembly. The annular feeding chain 3 is composed of two chains and a plurality of sprockets. The two chains are transmitted through a first transmission shaft 33 to achieve synchronization of the two chains. A plurality of detachable core shafts 31 are arranged between the two chains. In this embodiment, the core shaft 31 is connected to the chains at both ends by a snap-on method, that is, a snap seat is arranged on the chain, and then the two ends of the core shaft 31 are respectively snapped into the two snap seats to achieve the installation of the core shaft 31, so that the core shaft 31 moves with the annular feeding chain 3. It should be noted that the low position of the chain should be below the water surface of the first buffer pool 2, so that the core shaft 31 is immersed in water during low-position transportation, and the gel 9 thereon is immersed in water as much as possible to ensure the acid washing effect.

[0067] One end of the first transmission shaft 33 is a manual feed wheel 32, and the other end is connected to the power shaft of the peeling mechanism 1 through a transmission assembly, so that the power of the peeling mechanism 1 can be introduced into the annular feed chain 3 to drive the annular feed chain 3 to automatically feed, that is, to realize the automatic feeding of the gel 9. The feeding speed of the gel 9 is adapted to the peeling mechanism 1 to ensure that the thickness of the slices formed by cutting is uniform. Specifically, the transmission assembly includes a second transmission shaft 34, one end of the second transmission shaft 34 is connected to the power shaft of the peeling mechanism 1 through a gear, and the other end is connected to the first transmission shaft 33 through a sprocket chain. A clutch 35 is provided on the second transmission shaft 34 for cutting off the power, so that in special circumstances, the manual feed wheel 32 can be manually rotated to realize manual feeding of the gel 9. In this embodiment, the basic parameters of the peeling mechanism 1 are shown in Table 1:

[0068] Table 1

[0069] power About 4kW Applicable gel size (cylindrical) ≤Φ800X500 Peeling speed About 680m / h Gel processing capabilities About 6200kg / h Gel time of rotary cutting About 30 seconds Slice thickness (adjustable) 20±5mm

[0070] Furthermore, when the rotary cutter is rotary cutting, the rotary cutter rotates, which generates a lateral force on the gel 9, causing the position of the cut slice to shift. At the same time, the gel 9 is elastic, resulting in uneven thickness of the cut slice, and even a large difference in thickness between the left and right sides of the same slice. Therefore, the upper surface of the belt roller 4 of the present invention is provided with a pattern, and the pattern faces the moving direction of the rotary cutter. The roller surface pattern is used to provide a reverse force for the gel 9 to offset the force of the rotary cutter on it, which can effectively solve the problem of slice shift and uneven thickness.

[0071] Overlapping section Figure 4 As shown, the overlapping mechanism includes: a material discharging detection sensor 81, a clamping unit 82, a material breaking detection sensor 84 and a crimping unit 83. The clamping unit 82 is conveyed in a circular manner by the conveying chain 6. Two opposite clamping units 82 are respectively located on both sides of the sheet 91 to clamp the head of a sheet 91 together. Figure 5-7As shown, since the upstream peeling speed is relatively fast, the finished sheet 91 is in a thrown-out state when it leaves the conveying roller. In order to facilitate the subsequent clamping of the finished sheet by the clamping unit 82, the present invention is connected with a downwardly inclined blanking plate 85 at the discharge point of the peeling mechanism 1. The blanking plate 85 is used to receive the thrown-out finished sheet 91 and play a guiding role, thereby ensuring that the clamping unit 82 can accurately clamp the finished sheet 91.

[0072] The discharge detection sensor 81 is arranged at the entrance of the unloading plate 85, and is used to detect the head of the sheet 91. Specifically, the head of the sheet 91 is determined by detecting the material for the first time after the material is cut. The clamping unit 82 is located downstream of the discharge detection sensor 81. When the discharge detection sensor 81 detects the sheet 91, the clamping units 82 on both sides are activated to clamp the sheet 91. Then the conveying chain 6 moves to drive the sheet 91 to move toward the pressing roller 7. During the movement, the sheet 91 is always suspended on the water of the second buffer pool 5. While cleaning the surface of the sheet 91, it also overcomes the influence of gravity, which is convenient for the transportation of the sheet 91.

[0073] like Figure 8 As shown, the material break detection sensor 84 is located at the feeding end of the pressing roller 7, and the crimping unit 83 is located between the pressing roller 7 and the material break detection sensor 84. When the material break detection sensor 84 detects a material break, the pressing roller 7 stops running, and the tail of the previous sheet 91 stops in front of the pressing roller 7. At this time, the clamping unit 82 clamps a new sheet 91 to the material break detection sensor 84, and the clamping unit 82 releases the sheet 91. The clamping unit 82 moves in a circular motion and resets. The sheet 91 falls naturally and overlaps with the tail of the previous sheet 91. Then the crimping unit 83 operates to crimp the overlapping parts of the two sheets 91. The sheets 91 are connected together under pressure to form a continuous sheet. After the crimping is completed, the pressing roller 7 starts working to carry out the subsequent sheet pressing process. Specifically, the specific unloading position of the clamping unit 82 can be set so that the release position is as close to the crimping unit 83 as possible, or the broken material detection sensor 84 can be used to detect whether the sheet 91 has reached the crimping station, so that the rear clamping unit 82 delays the release of the sheet 91 to ensure that the front and rear sheets 91 always have overlapping parts.

[0074] Specifically, Fig. 9As shown, the clamping unit includes: a clamping motor 821, a fixed finger 822, a movable finger 823 and a mounting seat 824. The clamping unit is installed on the chain of the conveyor chain 6 through the mounting seat 824. The fixed finger 822 is fixedly connected to the mounting seat 824. The movable finger 823 is hinged at the connection between the fixed finger 822 and the mounting seat 824, and its end is an arc-shaped tooth. The output end of the clamping motor 821 is meshed with the arc-shaped tooth through a gear, and the movable finger 823 is driven to rotate by the clamping motor 821, thereby realizing the opening and closing of the clamping unit. When the discharge detection sensor 81 detects the head of the sheet 91, the clamping motor 821 drives the movable finger 823 to rotate and close, and clamps the head of the sheet 91 together with the fixed finger 822. After arriving at the crimping station, the clamping motor 821 reverses, opens the movable finger 823, and releases the sheet 91.

[0075] like Figure 8 As shown, the crimping unit 83 includes: a cylinder 831 and a pressing plate 832a. The output end of the cylinder 831 is fixedly connected to the pressing plate 832a. The piston of the cylinder 831 is extended and retracted to drive the pressing plate 832a to press down, thereby realizing the crimping of the overlapping parts of the two sheets 91.

[0076] Specifically, the working process of the device is as follows:

[0077] First, after the cylindrical gel 9 is sent into the first buffer pool 2, the mandrel 31 is manually removed from the circular feed chain 3, and the mandrel 31 is inserted into the center hole of the gel 9. Then, the mandrel 31 and the gel 9 are installed on the circular feed chain 3 together. The rotary cutting mechanism 1 transmits power to the circular feed chain 3 through the transmission component, driving the gel 9 to move forward with the mandrel 31, and the mandrel 31 moves clockwise with the circular feed chain 3, so that the gel 9 is transported at a low position. When the cylindrical gel 9 contacts the belt roller 4 at the rear end, the gel 9 rotates around the mandrel 31 under the friction of the belt roller 4, and the rotary cutter of the rotary cutting mechanism 1 cuts the rotating gel 9. While cutting, the gel 9 continues to feed along the circular feed chain 3, thereby realizing continuous slicing of the cylindrical gel 9. After completing the rotary cutting of one roll of gel 9, the rotary cutting of the next gel 9 is immediately started, and the mandrel 31 circulates back to the initial position along the circular feed chain 3.

[0078] After the sheet 91 cut from the cylindrical gel 9 is thrown out from the discharge end of the rotary cutting mechanism 1, it is detected by the discharge detection sensor 81 above, and the clamping motor 821 drives the movable finger 823 to rotate, and clamps the head of the sheet 91 together with the fixed finger 822 (during this process, the discharge end of the rotary cutting mechanism 1 continues to discharge). After the clamping unit 82 moves forward to the crimping station, the clamping motor 821 reverses, opens the movable finger 823, releases the sheet 91, and the head of the sheet 91 falls naturally and overlaps with the tail of the previous sheet 91. During this process, the clamping unit 82 keeps moving. Then the cylinder 831 moves, driving the pressure plate 832a to press down the overlapping parts of the two sheets 91, connecting the two sheets 91 together, thereby forming a continuous sheet. After the cylinder 831 is reset, the downstream pressure roller 7 starts, drives the sheet to move, and realizes the sheet pressing process.

[0079] Example 2

[0080] like Fig.10 As shown, in the present embodiment, a water spray assembly is provided at the inlet end of the blanking plate 85, and the water spray assembly is composed of a pump 86 and a water outlet pipe. The pump 86 pumps the water in the second buffer pool 5 to the water outlet pipe provided at the inlet end of the blanking plate 85, and then the water flows out from the water outlet pipe, so that a water flow 87 is formed on the surface of the blanking plate 85. The water flow 87 mainly serves to reduce the friction between the sheet 91 and the blanking plate 85, and at the same time gives a force to the sheet 91 to accelerate the movement of the head of the sheet 91, to avoid the head of the sheet 91 being retained, resulting in the rear end being clamped by the clamping unit 82, so as to improve the accuracy of the subsequent overlapping process.

[0081] In addition, the discharge roller of the rotary cutting mechanism 11 and the pressing roller of the sheet pressing mechanism may be provided with corresponding bumpers for spraying water to the sheets passing through these places, so as to keep a layer of water film on the surface of the sheets at all times and reduce adhesion.

[0082] Example 3

[0083] like Figure 11-13As shown, in this embodiment, the crimping member adopts an articulated crimping roller 832b, which is driven by the cylinder 831. Specifically, the output end of the cylinder 831 is provided with a support 833b, and the support 833b extends to the side of the material break detection sensor 84. The crimping roller 832b is articulated with the support 833b through a connecting member 835b. The hinge can be set relatively tight, but it does not affect its rotation, so that the crimping roller 832b can be kept pressed down into a sheet 91 without affecting its rotation. A limit block 834b is set on the support 833b. The limit block 834b is located at one end of the support 833b close to the material break detection sensor 84, and is used to limit the connection member 835b from rotating toward the side close to the material break detection sensor 84. When the overlapping parts of the two sheets 91 are pressed down, the piston of the cylinder 831 extends, driving the support 833b and the crimping roller 832b to descend, and the crimping roller 832b squeezes the overlapping parts of the two sheets 91. As the piston continues to extend, the connecting piece 835b gradually rotates around the hinge, so that the crimping roller 832b rolls the overlapping sheets 91 backwards, increasing the crimping area and avoiding the connection between the two sheets 91 being detached when the pressure roller 7 is started due to inadequate crimping.

[0084] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not used to limit the present invention. For those skilled in the art to which the present invention belongs, some simple deductions, modifications or substitutions can be made according to the idea of ​​the present invention.
