[0016] The utility model is described in further detail below in conjunction with the specific embodiment and the accompanying drawings:
[0017] As Figs. 1-3 shown, the application proposes a kind of milk strip cutting device, including the support frame being set on milk strip conveying belt upper portion, the top of support frame is provided with air cylinder, the piston rod of air cylinder is connected and fixed with guide frame, guide frame inside is provided with strip clamp block, strip clamp block is provided with the installation groove of inserting cutting plate, the buffer assembly for protecting cutting plate is set in this installation groove.
[0018] Air cylinder can adopt single-acting or double-acting cylinder, its piston rod stroke can be adjusted according to milk strip thickness.Guide frame is fixedly connected with piston rod by bolt or welding mode, ensure the stability of power transmission.Strip clamp block preferably adopts aluminium alloy material to reduce weight, the installation groove being opened in its inside is through groove structure, it is convenient for cutting plate to plug in and replace.Buffer assembly can select spring group, rubber pad or air cushion etc.elastic element, for absorbing impact force in cutting process.
[0019] The technical scheme effectively alleviates the direct impact of the cutting plate on the conveying belt by the arrangement of the buffer assembly. When the cylinder drives the cutting plate to press down, the buffer assembly first elastically deforms to absorb part of kinetic energy, and then the cutting plate contacts the milk strip to complete cutting. Thus, the cutting strength is ensured, and the hard collision of the metal blade with the conveying belt is avoided. Meanwhile, the cutting plate made of non-metal material can reduce the adhesion of the milk strip and improve the cutting quality. The device has simple and reliable structure, and solves the technical problems of the traditional metal blade which is easy to damage the conveying belt and adhere the milk strip.
[0020] Further, the application also proposes that the two sides of the guide frame are provided with sliding grooves which are slidingly connected with the side columns of the support frame. Linear bearings can be arranged in the sliding grooves to reduce frictional resistance. The sliding connection mode of the guide frame and the columns of the support frame can adopt clearance fit, and the fitting clearance is controlled within the range of 0.1-0.3mm to ensure the movement accuracy.
[0021] Specifically, the matching structure of the sliding groove and the column of the support frame enables the guide frame to keep straight-line movement in the vertical direction under the driving of the cylinder, avoiding lateral shaking during cutting. By adjusting the machining accuracy of the sliding groove, it can be ensured that the cutting plate and the conveying belt always keep a vertical relationship, thereby solving the problem of damage to the conveying belt caused by improper adjustment of the cylinder stroke. Compared with the traditional fixed guide device, this structure has higher movement stability and position adjustability.
[0022] Further, the application also proposes that the mounting groove includes a buffer groove and an expansion groove which are in communication with each other, and the top of the cutting plate is provided with a sliding block which is inside the buffer groove, and the cutting plate passes through the expansion groove and extends to the lower end of the strip-shaped clamping block.
[0023] The buffer groove is used to accommodate the sliding block and provide buffer space, and the expansion groove allows the cutting plate to move vertically. The sliding block is fixed on the top of the cutting plate and forms a sliding fit with the buffer groove. As a preferred embodiment, the sliding block can be made of wear-resistant material to reduce frictional wear. The width of the expansion groove is slightly larger than the thickness of the cutting plate to ensure smooth movement and prevent excessive shaking. The depth of the buffer groove is designed to be 1.2-1.5 times the stroke of the sliding block, leaving enough buffer space.
[0024] The technical scheme enables the cutting plate to absorb kinetic energy through the displacement of the sliding block in the buffer groove when it is impacted, by the matching structure of the buffer groove and the expansion groove. Specifically, when the cylinder drives the cutting plate to press down, the sliding block slides upward along the buffer groove to compress the buffer assembly, and the cutting plate extends downward through the expansion groove to perform cutting; after cutting is completed, the buffer assembly pushes the sliding block to reset, driving the cutting plate to retract. Thus, the damage of the cutting impact to the conveying belt is effectively alleviated, and the cutting plate can be accurately reset. Compared with the direct rigid connection cutting method, this structure significantly reduces the impact noise and component wear during equipment operation.
[0025] Further, the application also proposes that the buffer assembly comprises a plurality of compression springs arranged in the upper space of the sliding block in the buffer groove.
[0026] Specifically, the compression springs are uniformly distributed along the axial direction of the buffer groove, and the two ends of the spring are respectively clamped and fixed with the inner top of the buffer groove and the limiting groove arranged on the top of the sliding block. As a preferred embodiment, the compression spring can be made of stainless steel, and the wire diameter and the number of turns are adjusted according to the cutting impact force. Further, the limiting groove is a semispherical groove, and the end of the compression spring is provided with a spherical joint matched therewith, so as to realize the quick positioning and installation of the spring.
[0027] For this, the technical scheme absorbs the impact energy when the cutting plate is pressed down through the elastic deformation of the compression spring, thereby reducing the damage to the conveying belt. Since the springs are uniformly distributed in the upper space of the sliding block, the stable buffering of the cutting plate can be realized, and the cutting deviation caused by uneven stress can be avoided. Compared with the rigid impact in the prior art, the buffering structure significantly reduces the vibration and noise in the cutting process, and prolongs the service life of the cutting device.
[0028] Further, the application also proposes that the inner top of the buffer groove and the top of the sliding block are provided with a plurality of corresponding limiting grooves, and the limiting groove is clamped and arranged with the corresponding end of the compression spring.
[0029] Specifically, the limiting groove is a groove structure arranged on the top of the inner wall of the buffer groove and the upper surface of the sliding block, and the shape thereof is matched with the end of the compression spring. As a preferred embodiment, the limiting groove can adopt the forms of annular groove, semispherical groove or rectangular clamping groove, among which the annular groove can realize the circumferential positioning of the end of the spring, the semispherical groove is conducive to reducing the contact stress, and the rectangular clamping groove is convenient for axial alignment during assembly. The end of the compression spring is embedded in the limiting groove through interference fit or elastic deformation, thereby forming a stable three-dimensional space constraint.
[0030] For this, the technical scheme sets the limiting groove structure matched with each other, so that the compression spring always maintains the predetermined compression axis during the buffering process, and the elastic failure caused by lateral deviation is avoided. When the cutting plate is impacted, the spring generates uniform axial buffering force through the guiding action of the limiting groove, which not only protects the cutting plate from rigid impact, but also ensures the vertical precision of the cutting action. Compared with the spring buffering mode without positioning structure in the prior art, the scheme significantly improves the reliability and service life of the buffer assembly, and reduces the energy loss caused by the spring deviation.
[0031] Further, the application also proposes that the cutting plate is made of polytetrafluoroethylene and the lower part thereof is conical.
[0032] Specifically, polytetrafluoroethylene is a high polymer material with low friction coefficient and excellent anti-sticking properties, which can effectively reduce the sticking problem between the milk strip and the cutting plate during the cutting process. As a preferred embodiment, the conical design of the lower part of the cutting plate can further reduce the cutting resistance, making the cutting action more smooth. For example, the conical angle can be set between 30° and 60° to achieve the best cutting effect. In addition, the polytetrafluoroethylene material also has the characteristics of corrosion resistance and wear resistance, which can prolong the service life of the cutting plate.
[0033] Therefore, the technical scheme adopts the cutting plate made of polytetrafluoroethylene material and conical design, effectively solving the problems of sticking and large cutting resistance during the cutting process of the milk strip. Among them, the low friction characteristic of polytetrafluoroethylene reduces the adhesion between the milk strip and the cutting plate, and the conical design optimizes the distribution of cutting force, so that the cutting process is more efficient and the impact on the conveying belt is smaller. Therefore, while ensuring the cutting quality, the damage risk to the conveying belt is also reduced, and the overall operation stability of the equipment is improved.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
