Description

Technical Field

[0001] This utility model relates to the field of cutting mechanism technology, specifically a cutting mechanism for food packaging equipment. Background Technology

[0002] Cutting mechanisms in food packaging equipment are of great significance in biscuit packaging production. They can precisely cut continuous biscuit packaging strips, making the biscuits into individual packages, which is convenient for consumers to purchase and consume. This mechanism ensures the integrity and standardization of product packaging, enhances the overall image of the product, and the efficient cutting operation can improve production efficiency and meet the needs of large-scale production. At the same time, precise cutting can reduce the waste of packaging materials, lower production costs, and help food companies achieve efficient and economical production operations.

[0003] Cutting mechanisms can effectively cut food packaging and improve work efficiency, but they still have certain problems: after the food packaging is cut, the lack of traction below it can easily lead to poor cutting accuracy. Therefore, in view of the above situation, there is an urgent need to develop a cutting mechanism for food packaging equipment to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a cutting mechanism for food packaging equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting mechanism for food packaging equipment, comprising a cutting mechanism and a clamping member, wherein the clamping member is located at the bottom of the cutting mechanism, and a transmission component for transmission is installed between the cutting mechanism and the clamping member;

[0006] The cutting mechanism includes a drive assembly a, a cylinder, and a drive assembly b. Drive assembly a and drive assembly b are installed opposite each other. A spur gear for transmission is installed between drive assembly a and drive assembly b. The piston rod end of the cylinder is fixedly connected to one end of drive assembly a. A cutting blade is installed on the side of drive assembly a adjacent to drive assembly b. A cutting seat is installed on the side of drive assembly b adjacent to drive assembly a.

[0007] Preferably, the drive assembly a includes a drive frame, connecting rods, suspension, and rack a. Multiple connecting rods are slidably mounted on the suspension. The drive frame is fixed to one end of the connecting rods, and the cutting blade is fixed to the other end of the connecting rods. Multiple racks a are fixed to the lower surface of the drive frame, and the racks a mesh with spur gears. Specifically, the drive frame, in conjunction with the connecting rods, drives the cutting blade mounted at the end to move towards the cutting seat, thereby cutting the packaged food packaging.

[0008] Preferably, drive component b has the same structure as drive component a. Specifically, the two have the same structure and are distributed relatively. Due to the presence of the spur gear, when the cylinder drives drive component a to move towards the middle position, it can work with rack a and spur gear to drive drive component b on the opposite side to move towards the middle position synchronously, thereby realizing synchronous relative movement between the cutting blade and the cutting seat to perform the cutting action.

[0009] Preferably, the transmission assembly includes a transmission gear, a rack b, a drive plate, and a guide plate. The drive plate is located at the bottom edge of the drive assembly a and drive assembly b. The rack b is vertically fixed to the outer wall of the drive plate. The transmission gear is located between the rack a and the rack b, and both rack a and rack b mesh with the transmission gear. The guide plate is located on the outer wall of the drive plate. Specifically, the transmission assembly can drive the clamping member to move along the guide groove a and guide groove b when the drive assembly a moves horizontally. The clamping member clamps the food packaging to be cut and pulls it downward.

[0010] Preferably, the transmission gear is composed of a large gear and a small gear. The large gear meshes with rack a, and the small gear meshes with rack b. Specifically, the transmission ratio is controlled by the composite gear so that the cutting part and the clamping and traction part can work together.

[0011] Preferably, the clamping member has a sliding shaft a and a sliding shaft b fixed on its side, and a clamping block fixed at its bottom end. Specifically, the clamping member has two sets of clamping members that are distributed relative to each other, and the clamping effect is achieved by the two clamping blocks that are distributed relative to each other approaching each other.

[0012] Preferably, the drive plate has drive groove a and drive groove b, and the guide plate has guide groove a and guide groove b, with guide groove a and guide groove b connected.

[0013] Preferably, the sliding shaft a can be slidably inserted into the drive groove a, and the sliding shaft b can be slidably inserted into the drive groove b, the guide groove a, and the guide groove b. Specifically, it can restrict the movement of the clamping member along the path of the guide groove a and the guide groove b.

[0014] Compared with the prior art, the present invention provides a cutting mechanism for food packaging equipment, which has the following beneficial effects:

[0015] This equipment utilizes a relative-motion cutting mechanism to precisely cut food packaging. Employing a centered cutting method effectively prevents the food packaging bag from shifting during the cutting process, ensuring accurate cutting position. Simultaneously, the transmission component synchronously drives the clamping components to move diagonally downwards. Two sets of clamping components, in conjunction with the flexible clamping block at the end, firmly clamp the food packaging and pull it downwards a certain distance. This process stabilizes the food packaging bag and applies traction before cutting, significantly improving cutting accuracy and ensuring the efficiency and stability of the entire cutting process.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example:

[0024] Please see Figures 1-3 The present invention provides a technical solution: a cutting mechanism for food packaging equipment, including a cutting mechanism 100 and a clamping member 300, the clamping member 300 being located at the bottom of the cutting mechanism 100, and a transmission assembly 200 for transmission being installed between the cutting mechanism 100 and the clamping member 300.

[0025] The cutting mechanism 100 includes a drive assembly a110, a cylinder 120, and a drive assembly b130. The drive assembly a110 and the drive assembly b130 are mounted opposite each other. A spur gear 140 for transmission is installed between the drive assembly a110 and the drive assembly b130. The piston rod end of the cylinder 120 is fixedly connected to one end of the drive assembly a110. A cutting blade 160 is installed on the side of the drive assembly a110 adjacent to the drive assembly b130. A cutting seat 150 is installed on the side of the drive assembly b130 adjacent to the drive assembly a110.

[0026] Preferably, the drive assembly a110 includes a drive frame 111, a connecting rod 112, a suspension 113, and a rack a114. Multiple connecting rods 112 are slidably mounted on the suspension 113. The drive frame 111 is fixed to one end of the connecting rod 112, and the cutting blade 160 is fixed to the other end of the connecting rod 112. Multiple racks a114 are fixed to the lower surface of the drive frame 111, and the racks a114 mesh with spur gears 140. Specifically, the drive frame 111, in conjunction with the connecting rod 112, drives the cutting blade 160 mounted at the end to move toward the cutting seat 150, thereby cutting the packaged food packaging.

[0027] Preferably, the drive assembly b130 and the drive assembly a110 have the same structure. Specifically, they have the same structure and are distributed relative to each other. Due to the presence of the spur gear 140, when the cylinder 120 drives the drive assembly a110 to move towards the middle position, the rack a114 and the spur gear 140 work together to drive the opposite drive assembly b130 to move towards the middle position synchronously. This enables the cutting blade 160 and the cutting seat 150 to move synchronously relative to each other and perform the cutting action.

[0028] Preferably, the transmission assembly 200 includes a transmission gear 210, a rack b220, a drive plate 230, and a guide plate 240. The drive plate 230 is located at the bottom edge of the drive assembly a110 and the drive assembly b130. The rack b220 is vertically fixed to the outer wall of the drive plate 230. The transmission gear 210 is located between the rack a114 and the rack b220, and both the rack a114 and the rack b220 mesh with the transmission gear 210. The guide plate 240 is located on the outer wall of the drive plate 230. Specifically, the transmission assembly 200 can drive the clamping member 300 to move along the guide groove a241 and the guide groove b242 when the drive assembly a110 moves horizontally. The clamping member 300 clamps the food packaging to be cut and pulls it downward.

[0029] Preferably, the transmission gear 210 is composed of a large gear 212 and a small gear 211. The large gear 212 meshes with the rack a114, and the small gear 211 meshes with the rack b220. Specifically, the transmission ratio is controlled by the composite gear so that the cutting part and the clamping and traction part can work together.

[0030] Preferably, the side of the clamping member 300 is fixed with a sliding shaft a310 and a sliding shaft b320, and the bottom end of the clamping member 300 is fixed with a clamping block 330. Specifically, the clamping member 300 is provided with two sets and is distributed relative to each other. The clamping effect is achieved by the two clamping blocks 330 being distributed relative to each other and moving closer together.

[0031] Preferably, the drive plate 230 has drive grooves a231 and b232, and the guide plate 240 has guide grooves a241 and b242, with guide grooves a241 and b242 communicating with each other.

[0032] Preferably, the sliding shaft a310 is slidably disposed within the drive groove a231, and the sliding shaft b320 is slidably disposed within the drive groove b232, the guide groove a241, and the guide groove b242. Specifically, it can restrict the movement of the clamping member 300 along the path of the guide groove a241 and the guide groove b242.

[0033] Working principle: During operation, the continuous food packaging is inserted from top to bottom into the middle position of the cutting mechanism 100. The cylinder 120 drives the drive assembly a110 to move towards the middle position, which in turn drives the drive assembly b130 to move towards the middle position simultaneously with the spur gear 140. Finally, the cutting blade 160 contacts the cutting seat 150 and cuts the food packaging between them. During this process, the transmission assembly 200 drives the clamping member 300 to move towards the food packaging and clamp it, and then pulls it downward a certain distance; the cylinder 120 drives the drive frame 111 to move. At the same time, it will work with the connecting rod 112 to drive the cutting blade 160 to move. At the same time, it will drive the rack b220 and the drive plate 230 to move downward through the rack a114 and the transmission gear 210. When the drive plate 230 moves to the bottom, it will drive the clamping member 300 to move downward through the drive groove a231 and drive groove 232. Due to the presence of the guide plate 240, the path of the clamping member 300 will change when it moves downward. It will move along the guide groove a241 and guide groove b242, so as to achieve the effect of first clamping the food packaging and then applying traction downward after clamping.
