Description

Technical Field

[0001] This utility model belongs to the field of slicing machine technology, specifically, it relates to a slicing machine that is easy to adjust. Background Technology

[0002] In product processing, a slicing machine is generally needed to cut rolls of PP into PP sheets of the appropriate size; Existing cam-type reciprocating slicers have a fixed cutting stroke when used for thin slices, and cannot be adaptively adjusted according to the thickness of the PP material to be sliced. If the PP material to be sliced ​​is thick, the fixed short stroke may cause the cutter to fail to completely cut the material, resulting in "cutting stubble". If the PP material to be sliced ​​is thin, the fixed long stroke will cause the cutter to have too much idle stroke, which not only increases the energy consumption of the equipment, but also reduces the slicing efficiency. In view of the above problems, a slicer that is easy to adjust is proposed here. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a conveniently adjustable slicer that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A conveniently adjustable slicer includes a chassis and a discharge box fixedly mounted on the chassis. The chassis is equipped with a feeding assembly for conveying materials and a slicing assembly for cutting materials. An eccentric wheel is rotatably mounted on the chassis. A second motor with an output shaft fixedly connected to the eccentric wheel is fixedly mounted on the chassis. A second slider is slidably mounted on the eccentric wheel. A crank is hinged to the second slider and connected to the slicing assembly. A first lead screw is rotatably mounted on the eccentric wheel. The first lead screw is threadedly connected to the second slider. A spline head is fixedly mounted on the end of the first lead screw away from the second slider.

[0005] In a preferred embodiment of this utility model: the feeding assembly includes a driving roller and a driven roller. The driving roller is rotatably mounted on the housing. The housing is provided with a limiting groove. A first slider is slidably mounted in the limiting groove. The driven roller is rotatably mounted on the first slider. A first motor is fixedly mounted on the outer wall of the housing. The output shaft of the first motor is fixedly connected to the driving roller. The housing is provided with an adjustment part for adjusting the cutting stroke of the slicing assembly and the height of the driven roller.

[0006] In a preferred embodiment of the present invention, the slicing assembly includes a slide rail fixedly mounted on the outer wall of the chassis, and a cutter is slidably mounted on the slide rail.

[0007] In a preferred embodiment of this utility model: the adjusting part includes a third motor fixedly installed on the outer wall of the chassis, the output shaft of the third motor extending into the chassis and a spline sleeve fixedly installed thereon, a spline shaft slidably installed on the spline sleeve, the spline shaft having an internal spline hole adapted to the spline head, an electric telescopic rod fixedly installed inside the chassis, an mounting plate fixedly installed at the output end of the electric telescopic rod, and the spline shaft rotatably connected to the mounting plate; a threaded cylinder rotatably installed on the chassis, a second lead screw threadedly connected to the threaded cylinder, a connecting arm fixedly installed at the bottom of the second lead screw, the connecting arm being connected to a first slider through a first connecting rod, and a gear transmission group rotatably installed on the chassis, the threaded cylinder and the spline sleeve being connected by the gear transmission group.

[0008] In a preferred embodiment of this utility model: an upper pressure box and a lower pressure box are symmetrically arranged on the chassis. Both the upper and lower pressure boxes are provided with air chambers. Each of the upper and lower pressure boxes has a diversion hole on its opposite side. The lower pressure box is fixedly installed on the chassis. The lower pressure box has a cutting edge that cooperates with the cutter. A sliding rod is fixedly installed on the top of the upper pressure box. The sliding rod is slidably arranged with the chassis.

[0009] In a preferred embodiment of this utility model: a connecting plate is hinged to the bottom of the crank, a second connecting rod is fixedly installed at the bottom of the connecting plate, a sliding plate is fixedly installed at the bottom of the second connecting rod, the second connecting rod is slidably connected to the chassis, the cutter is fixedly installed on the sliding plate, and the sliding plate is slidably connected to the slide rod.

[0010] In a preferred embodiment of this utility model, a spring is fitted onto the slide rod, and the two ends of the spring are fixedly connected to the slide plate and the upper pressure box, respectively.

[0011] In a preferred embodiment of this utility model: a first air pump and a second air pump are fixedly installed inside the casing. The exhaust pipes of the first air pump and the second air pump are respectively connected to the upper pressure box and the lower pressure box. The drive rods of the first air pump and the second air pump are both fixedly connected to the connecting plate. When the connecting plate descends, the first air pump and the second air pump draw in external air. When the connecting plate rises, the first air pump and the second air pump discharge the air into the air chambers of the upper pressure box and the lower pressure box respectively. Then the gas is discharged through the diversion hole to blow the material, preventing the material from adsorbing onto the upper pressure box or the lower pressure box.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: This invention adjusts the position of the crank on the eccentric wheel, thereby changing the amplitude of the crank's movement and ultimately adjusting the cutting stroke of the cutter. This allows it to adapt to materials of different thicknesses: when dealing with thicker materials, increasing the cutting stroke ensures that the cutter completely cuts through the material, thoroughly solving the problem of continuous cutting caused by the fixed stroke in traditional slicing machines and reducing waste. When dealing with thinner materials, reducing the cutting stroke significantly shortens the cutter's idle time, reducing unnecessary energy consumption and avoiding idle time from occupying processing time, thus effectively improving slicing efficiency.

[0013] In this invention, the gap between the feeding rollers and the stroke of the cutter are adjusted synchronously by means of an adjustment structure, which not only enables the cutting of materials of different thicknesses, but also prevents the materials from slipping during feeding and improves the adjustment efficiency.

[0014] In this invention, when the cutter rises, the air pump is driven to blow air in conjunction with the upper and lower pressure boxes to form an air film between the material and the pressure boxes, which avoids material adsorption, prevents material wrinkling and damage, reduces losses, and ensures smooth conveying.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example: Refer to Figures 1-6 A slicing machine that is easy to adjust includes a machine housing 1 and a discharge box 11 fixedly installed on the machine housing 1. The machine housing 1 is provided with a feeding component 2 for conveying materials and a slicing component for cutting materials. The feeding component 2 conveys the materials, and then the slicing component slices the materials.

[0020] Reference Figure 1 and Figure 4 The feeding assembly 2 includes a drive roller 22 and a driven roller 24. The drive roller 22 is rotatably mounted on the housing 1. The housing 1 is provided with a limit groove 12. A first slider 23 is slidably mounted in the limit groove 12. The driven roller 24 is rotatably mounted on the first slider 23. A first motor 21 is fixedly mounted on the outer wall of the housing 1. The output shaft of the first motor 21 is fixedly connected to the drive roller 22. The housing 1 is provided with an adjustment part for adjusting the cutting stroke of the slicing assembly and the height of the driven roller 24.

[0021] When the feeding assembly 2 is working, the position of the first slider 23 in the limiting slide groove 12 is first adjusted by the adjustment part on the housing 1, and then the height of the driven roller 24 rotatably mounted on the first slider 23 is adjusted so that the driven roller 24 and the driving roller 22 cooperate to clamp the material to be conveyed; then, the first motor 21 fixed on the outer wall of the housing 1 is started, and its output shaft drives the driving roller 22 to rotate. The driving roller 22, in the clamping cooperation with the driven roller 24, drives the material to move towards the slicing assembly, and cooperates with the slicing assembly to slice the material.

[0022] Reference Figures 1-5The slicing assembly includes a slide rail 3 fixedly mounted on the outer wall of the casing 1, with a cutter 31 slidably mounted on the slide rail 3; an upper pressure box 4 and a lower pressure box 41 are symmetrically arranged on the casing 1, each containing an air chamber 42, and a diversion hole 43 on the opposite side of each of the upper and lower pressure boxes 41; the lower pressure box 41 is fixedly mounted on the casing 1, and has a cutting edge that cooperates with the cutter 31; a slide rod 44 is fixedly mounted on the top of the upper pressure box 4, and slides with the casing 1; an eccentric wheel 53 is rotatably mounted on the casing 1, and a second motor 52 is fixedly mounted on the casing 1, with the output shaft of the second motor 52 fixedly connected to the eccentric wheel 53; the eccentric wheel 53... A second slider 56 is slidably mounted, a crank 57 is hinged to the second slider 56, a connecting plate 5 is hinged to the bottom of the crank 57, a second connecting rod 51 is fixedly mounted to the bottom of the connecting plate 5, a slide plate 58 is fixedly mounted to the bottom of the second connecting rod 51, the second connecting rod 51 is slidably connected to the housing 1, a cutter 31 is fixedly mounted on the slide plate 58, the slide plate 58 is slidably connected to the slide rod 44; a first lead screw 54 is rotatably mounted on the eccentric wheel 53, the first lead screw 54 is threadedly connected to the second slider 56, a spline head 55 is fixedly mounted on the end of the first lead screw 54 away from the second slider 56; a spring 45 is sleeved on the slide rod 44, the two ends of the spring 45 are fixedly connected to the slide plate 58 and the upper pressure box 4 respectively.

[0023] When the slicing assembly is working, the second motor 52 starts and drives the eccentric wheel 53 to rotate. During the rotation of the eccentric wheel 53, the second slider 56 drives the crank 57 to move. The crank 57 then pulls the connecting plate 5 to move up and down. The connecting plate 5 drives the slide plate 58 to move through the second connecting rod 51. The slide plate 58 drives the upper pressure box 4 to slide up and down along the machine box 1 through the spring 45. At the same time, the spring 45 on the slide rod 44 deforms with the movement of the upper pressure box 4, which helps the upper pressure box 4 to reset and provides a buffer distance between the upper pressure box 4 and the material. After the upper pressure box 4 first contacts the material, the cutter 31 continues to slide down along the slide rail 3 under the buffer distance provided by the spring 45, and cooperates with the edge on the lower pressure box 41 to complete the cutting of the material. If the cutting stroke needs to be adjusted, the first lead screw 54 can be rotated by the spline head 55. The first lead screw 54 is threadedly engaged with the second slider 56, which drives the second slider 56 to slide on the eccentric wheel 53, thereby changing the movement amplitude of the crank 57 and adjusting the cutting stroke.

[0024] Reference Figure 3 , Figure 4 and Figure 6The adjustment unit includes a third motor 7 fixedly installed on the outer wall of the housing 1. The output shaft of the third motor 7 extends into the housing 1 and is fixedly installed with a spline sleeve 74. A spline shaft 73 is slidably installed on the spline sleeve 74. The spline shaft 73 is provided with an inner spline hole that is adapted to the spline head 55. An electric telescopic rod 71 is fixedly installed inside the housing 1. An installation plate 72 is fixedly installed at the output end of the electric telescopic rod 71. The spline shaft 73 is rotatably connected to the installation plate 72. A threaded cylinder 75 is rotatably mounted on the housing 1. A second lead screw 77 is threadedly connected to the threaded cylinder 75. A connecting arm 26 is fixedly mounted at the bottom of the second lead screw 77. The connecting arm 26 is connected to the first slider 23 through a first connecting rod 25. A gear transmission group 76 is rotatably mounted on the housing 1. The threaded cylinder 75 and the spline sleeve 74 are connected by the gear transmission group 76.

[0025] When the rotation axis of the spline head 55 coincides with the rotation axis of the spline shaft 73, the electric telescopic rod 71 drives the spline shaft 73 to move toward the spline head 55 and engage the two.

[0026] In summary, when using this slicer, the height of the driven roller 24 and the slicing stroke are preset by the adjustment unit, specifically as follows: The third motor 7 drives the spline sleeve 74 to rotate. The spline sleeve 74 drives the threaded cylinder 75 to rotate through the gear transmission group 76, causing the second lead screw 77 to rise and fall axially. Through the connecting arm 26 and the first connecting rod 25, the first slider 23 is pulled to slide along the limiting slide groove 12, and finally the gap between the driven roller 24 and the driving roller 22 is adjusted to adapt to the thickness of the material to be cut. When the third motor 7 is working, the spline head 55 is inserted into the spline shaft 73, and the spline sleeve 74 drives the spline head 55 to rotate through the spline shaft 73, which in turn drives the first lead screw 54 to rotate. The first lead screw 54 drives the second slider 56 to slide, adjusting the distance between the second slider 56 and the rotation axis of the eccentric wheel 53. During adjustment, when the third motor 7 drives the driven roller 24 away from the driving roller 22, the third motor 7 drives the second slider 56 to move towards the eccentric position of the eccentric wheel 53. That is, the thicker the material, the greater the cutting stroke of the cutter 31, and the mechanical transmission ratio of the distance of the driven roller 24 rising and falling to the stroke adjustment distance of the cutter 31 is 1:1.

[0027] Reference Figure 3 and Figure 4The first air pump 6 and the second air pump 61 are fixedly installed inside the casing 1. Both the air inlet and outlet ends of the air pump body are equipped with one-way valves. The exhaust pipes of the first air pump 6 and the second air pump 61 are connected to the upper pressure box 4 and the lower pressure box 41, respectively. The drive rods of the first air pump 6 and the second air pump 61 are fixedly connected to the connecting plate 5. When the connecting plate 5 descends, the first air pump 6 and the second air pump 61 draw in external air. When the connecting plate 5 rises, the first air pump 6 and the second air pump 61 discharge the air into the air chambers 42 of the upper pressure box 4 and the lower pressure box 41, respectively. Then the gas is discharged through the diversion hole 43 to blow the material, preventing the material from adsorbing with the upper pressure box 4 or the lower pressure box 41.
