Description

Technical Field

[0001] This utility model belongs to the technical field of polymer material cutting devices, and specifically relates to a polymer material cutting device and an anti-deviation structure. Background Technology

[0002] Existing polymer cutting devices have significant problems in preventing material deviation during cutting and feeding. These problems primarily manifest as positional shifts, slippage, or jamming during material transport and cutting, thus affecting cutting accuracy and production efficiency. This phenomenon typically stems from the inherent flexibility and uneven surface friction properties of polymer materials, making them prone to non-uniform deformation or slippage under mechanical force. Simultaneously, the feeding mechanism design in some devices is inadequate, failing to achieve stable clamping and precise feeding of the material, resulting in inaccurate cutting positioning. The root cause of these problems lies in the system control logic and mechanical structure failing to adequately adapt to the physical properties of polymer materials, especially evident in continuous multi-segment cutting scenarios.

[0003] Conventional solutions include increasing mechanical clamping points to enhance the fixing effect, optimizing the stroke control accuracy of the feeding mechanism, or using auxiliary guiding devices to improve material stability. However, these methods often lead to increased equipment complexity and maintenance costs, and excessive clamping may cause localized pressure deformation or even damage to the material, thus affecting the quality of the finished product. Therefore, we aim to design a polymer material cutting device with a novel structure to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polymer material cutting device and an anti-deviation structure to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a polymer material cutting device and an anti-deviation structure, comprising: a base and an anti-deviation component, wherein a conveying component for conveying and pushing polymer material is slidably installed on the front side of the upper end of the base, and a cutting component for cutting polymer material is slidably installed on the rear side of the upper end of the base;

[0006] The upper left and right sides of the base are respectively fixed with a transmission gear for transmission. The upper middle of the base is provided with anti-deviation components at the front and rear. The conveying component includes a lifting plate. The lower end of the lifting plate is equipped with a conveyor belt for pushing the polymer material. The cutting component includes a pressing plate. The upper side of the pressing plate is equipped with a cutting saw blade and a drive motor and reducer for driving the cutting saw blade.

[0007] In a preferred embodiment, the front side of the transmission gear is meshed with the rear side of the rack on the rear side of the lifting plate, and the rear side of the transmission gear is meshed with the front side of the rack on the front side of the pressing plate.

[0008] In a preferred embodiment, the anti-deviation component includes a guide trough, which is recessed in the middle to form a conveying trough. An extrusion plate is movably installed on the left and right sides of the guide trough. In actual use, the height of the extrusion plate matches the depth of the conveying trough, which facilitates the subsequent conveyor belt to transport polymer materials.

[0009] In a preferred embodiment, telescopic rods for driving the extrusion plates to move in opposite directions are respectively installed on the left and right sides of the front end and the left and right sides of the rear end of the guide trough. The inner end of the telescopic rod passes through the guide trough and is fixedly connected to the outer side of the extrusion plate. In actual use, the guide trough is divided into a front part and a rear part, and a gap is set between the two parts. The gap is slightly larger than the thickness of the cutting saw blade and can discharge waste chips. The extrusion plate is also divided into front and rear parts, and a clearance is reserved in the same way.

[0010] In a preferred embodiment, the middle left side of the lifting plate is fixedly connected to the lower end of the lead screw module, and the conveyor belt is located directly above the guide trough.

[0011] In a preferred embodiment, the height of the conveying component is greater than the height of the cutting component when the conveying component is not in operation, and the height of the conveying component is less than the height of the cutting component when the conveying component is in operation.

[0012] In a preferred embodiment, the clamping plate has a transverse clearance strip hole in the middle for the cutting saw blade to make way. The front and rear sides of the lower surface of the clamping plate are respectively elastically installed with clamping blocks by guide rods and springs. The clamping blocks are made of rubber.

[0013] In a preferred embodiment, the upper side of the guide rod passes through the clamping plate and is slidably connected thereto, the lower end of the guide rod is fixedly connected to the upper side of the clamping block, and both clamping blocks are placed directly above the conveying channel of the guide trough, with their width being smaller than the width of the conveying channel.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting the conveying component and the base, it is possible to ensure that the polymer material can reduce its offset when it is pushed and fed to the cutting component, which helps to ensure the stability of the polymer material movement and the accuracy of cutting. This solves the problem that increasing mechanical clamping points to enhance the fixing effect, optimizing the stroke control accuracy of the pushing mechanism, or using auxiliary guiding devices to improve material stability may lead to local pressure deformation or even damage to the material, thereby affecting the quality of the finished product.

[0015] 2. Setting up the cutting assembly: Start the lead screw module to lift the lifting plate. Under the action of the transmission gear, the pressure plate moves down. At this time, the two pressure blocks on the pressure plate press and fix the polymer material. Simultaneously, start the telescopic rod to drive the extrusion plate to fix the polymer material. Then, start the drive motor to drive the cutting saw blade to cut the polymer material stably, avoiding the polymer material from shifting during the cutting process. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] As the first embodiment of this utility model:

[0027] Please see Figures 1 to 5 A polymer material cutting device and anti-deviation structure, comprising: a base 100, an anti-deviation component 120, a conveying assembly 200 for conveying and pushing polymer material slidably installed on the front side of the upper end of the base 100, and a cutting assembly 300 for cutting polymer material slidably installed on the rear side of the upper end of the base 100.

[0028] A transmission gear 110 for transmission is fixed on the left and right sides of the upper middle of the base 100. Anti-deviation components are arranged at the front and rear of the upper middle of the base 100. The conveying component 200 includes a lifting plate 210. A conveyor belt 240 for pushing polymer materials is installed at the lower end of the lifting plate 210. The cutting component 300 includes a pressing plate 310. A cutting saw blade 320 and a drive motor and reducer for driving the cutting saw blade 320 are installed on the upper side of the pressing plate 310.

[0029] The front side of the transmission gear 110 meshes with the rear side of the rack 230 on the rear side of the lifting plate 210, and the rear side of the transmission gear 110 meshes with the front side of the rack 330 on the front side of the pressing plate 310.

[0030] The anti-deviation component 120 includes a guide trough 121, which is recessed in the middle to form a conveying trough. An extrusion plate 122 is movably installed on the left and right sides of the guide trough 121. In actual use, the height of the extrusion plate 122 matches the depth of the conveying trough, which facilitates the subsequent conveyor belt 240 to convey polymer materials.

[0031] Telescopic rods 123 for driving the extrusion plate 122 to move in opposite directions are respectively installed on the left and right sides of the front end and the left and right sides of the rear end of the guide trough 121. The inner end of the telescopic rod 123 passes through the guide trough 121 and is fixedly connected to the outer side of the extrusion plate 122. In actual use, the guide trough 121 is divided into a front part and a rear part, and a gap is set between the two parts. The gap is slightly larger than the thickness of the cutting saw blade 320 and can discharge waste chips. The extrusion plate 122 is also divided into front and rear parts, and a clearance is reserved in the same way.

[0032] The middle left side of the lifting plate 210 is fixedly connected to the lower end of the lead screw module 220, and the conveyor belt 240 is located directly above the guide trough 121.

[0033] When the conveying component 200 is not in operation, its height is greater than that of the cutting component 300; when the conveying component 200 is in operation, its height is less than that of the cutting component 300.

[0034] Specifically, by setting up the conveying assembly 200 and the base 100, in actual use, if it is necessary to convey polymer materials, the lead screw module 220 drives the lifting plate 210 to move downward. Since the front side of the transmission gear 110 is meshed with the rear side of the rack 230 on the rear side of the lifting plate 210, and the rear side of the transmission gear 110 is meshed with the front side of the rack 330 on the front side of the pressing plate 310, the lifting plate 210 moves downward, thereby causing the transmission gear 110 to drive the pressing plate 310 to move upward. At this time, the part that has been cut and the part that needs to be cut later are released from fixation. Then, the telescopic rod 123 is activated, so that the extrusion plate 122 is detached from the polymer material. Then, the conveyor belt 240 can be activated to convey the polymer material to the position of the cutting saw blade 320. Under the conveying of the conveyor belt 240 and the guiding action of the extrusion plates 122 on both sides, the extrusion plate 122 is released from the extrusion fixation of the polymer material, but this is only... The material is loose but not directly detached, with a small gap between them, ensuring that the polymer material can slide back and forth without significant displacement. The longer conveyor belt 240 extrusion drive also reduces the displacement of the polymer material when it is pushed. The telescopic rod 123 can be selected as an electric cylinder, pneumatic cylinder, etc., as long as it can drive the extrusion plate 122. Its micro-adjustment function of the extrusion plate 122 can be met by existing products on the market. It is existing technology, and its specific structure and principle will not be elaborated here. It can ensure that the polymer material can reduce its displacement when it is pushed and fed to the cutting component 300, which helps to ensure the stability of the polymer material movement and the accuracy of cutting. It solves the problem that excessive clamping may cause local pressure deformation or even damage to the material, thus affecting the quality of the finished product, by increasing mechanical clamping points to enhance the fixing effect, optimizing the stroke control accuracy of the pushing mechanism, or using auxiliary guiding devices to improve material stability.

[0035] As a second embodiment of this utility model:

[0036] Please see Figures 1 to 5 The clamping plate 310 has a transverse clearance strip hole in the middle for the cutting saw blade 320 to make way. The front and rear sides of the lower surface of the clamping plate 310 are elastically installed with clamping blocks on the upper and lower sides by guide rods and springs, respectively. The clamping blocks are made of rubber.

[0037] The upper side of the guide rod passes through the clamping plate 310 and is slidably connected to it. The lower end of the guide rod is fixedly connected to the upper side of the clamping block. Both clamping blocks are placed directly above the conveying trough of the guide trough 121, and their width is smaller than the width of the conveying trough.

[0038] Based on the first embodiment described above, in actual use, after the polymer material reaches the designated cutting position (a sensor is installed on the rear side of the guide trough 121 to detect the position of the object and thus determine whether the polymer material has reached the designated position), the screw module 220 is activated to lift the lifting plate 210. Under the action of the transmission gear 110, the clamping plate 310 moves down. At this time, the two clamping blocks on the clamping plate 310 clamp and fix the polymer material, and the telescopic rod 123 is activated simultaneously to drive the extrusion plate 122 to fix the polymer material. Then, the drive motor of the cutting saw blade 320 can be started to stably cut the polymer material, avoiding the polymer material from shifting during the cutting process.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
