Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to an adjustable mixing silicone rubber cutting equipment. Background Art

[0002] The traditional rubber cutting process is to adjust the cutting width, depth and angle according to user requirements to meet the processing requirements of compounded silicone rubber products of different sizes, specifications and shapes. The compounded silicone rubber is extruded from the extrusion port with a rectangular cross-section. The length of the extruded compounded silicone rubber is controlled according to the running speed of the conveyor belt and the frequency of the cutting blade falling to ensure that its shape is a rectangular parallelepiped. However, due to the certain fluidity of compounded silicone rubber, especially the compounded silicone rubber with lower hardness, there is a large deformation during transportation, resulting in the cutting process cannot control the weight of the finished compounded silicone rubber, resulting in a large error in the weight of the product after packaging.

[0003] In the prior art, for example, the patent CN216266229U discloses an adjustable silicone rubber mixed film cutting device. The patent uses the conical roller, the first rotating shaft, and the roller to adjust the rotation speed of the roller by adjusting the position of the roller on the first rotating shaft, thereby controlling the up and down movement speed of the slide rod driven by the turntable. When the conveyor belt speed remains unchanged, the faster the up and down movement speed of the cutting knife, the smaller the cutting interval, and the thinner the silicone rubber mixed film; the position of the roller can be changed at any time through the set telescopic device; the square limit block can be used to control the slide rod from rotating, so that the cutting knife can maintain vertical up and down movement. However, the above patent is for mixed silicone rubber with lower hardness. Due to its large flow performance, its weight cannot be controlled, which makes the weight of the mixed silicone rubber block after cutting inconsistent and fails to meet the specified standard. Therefore, an adjustable mixed silicone rubber cutting device is proposed to solve the above technical problems. Utility Model Content

[0020] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0022] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] One of the preferred embodiments of the present application is as follows: Figures 1 to 4 As shown, an adjustable mixed silicone rubber cutting device includes a workbench 1 and a cutting device 2, a conveying device 3, a detection device 4 and a control panel (not shown) installed on the workbench 1, and the cutting device 2, the conveying device 3, and the detection device 4 are all electrically connected to the control panel.

[0024] It should be noted that the electrical control method used in this application document is automatically controlled through a control panel (controller) and powered by an external power supply. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in the field. This application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.

[0025] It can be understood that when cutting the product (mixed silicone rubber raw material with lower hardness), the product is first placed on the conveying device 3, and then the conveying device 3 can convey the product to the detection device 4. As the product is continuously conveyed, the detection value of the product by the detection device 4 is also constantly changing. When the detection device 4 detects that the weight of the product reaches the set weight value, the control panel will drive the conveying device 3 to stop, and then the control panel will drive the cutting device 2 to cut the product so that the cut product reaches the desired weight. In this way, the weight of each mixed silicone rubber product required can be adjusted according to specific needs, avoiding the subsequent weighing and verification and manual cutting of mixed silicone rubber to meet the factory standards. This process improves workshop production efficiency, reduces labor costs, and also improves product consistency and quality stability. This automated production method not only improves production efficiency, but also reduces the impact of human factors on product quality, providing a more reliable guarantee for the company's production.

[0026] It should be known that when the next cutting is performed, the detection device 4 will reset the weight, the cutting device 2 will be reset, and the subsequent mixed silicone rubber product will continue to be conveyed by the conveying device 3, and the above steps can be repeated reciprocally.

[0027] One of the embodiments of the present application is as follows: Figure 1 As shown, the conveying device 3 includes a belt conveyor 301, and the belt conveyor 301 is installed on the top of the workbench 1; it can be understood that the belt conveyor 301 conveys the product by rotating the conveyor belt, and the detection device 4 cooperates with the top of the inner conveyor belt to perform weight detection on the conveyed product.

[0028] Specifically, after the product is placed on the conveyor belt, we know that the conveyor belt is elastic. Therefore, when the conveyor belt transports the product to the position of the detection device 4, the product will exert pressure on the detection device 4 through the conveyor belt, and the detection device 4 can detect the weight of the product through pressure sensing.

[0029] As a further description of the above embodiment: the detection device 4 includes a pressure-sensitive device 401, which can detect the weight of the products on the conveyor belt.

[0030] Specifically, the pressure-sensitive device 401 mainly includes a piezoresistor, which is similar to the principle of an electronic scale. A piezoresistor is a resistor element that converts pressure into a change in resistance value, and has the advantages of high sensitivity, good stability, and fast response speed. The piezoresistor sensor can change the resistance value according to the pressure it receives. When the resistance value changes to a certain extent, it represents the pressure or weight applied by the object. By converting the resistance value into a digital signal, the weighing function of the product can be realized.

[0031] One of the embodiments of the present application is as follows: Figure 1 and Figure 2 As shown, the cutting device 2 includes a frame 201, a driving device 203 and a blade 202. The frame 201 is installed on the top of the workbench 1, the driving device 203 is installed on the top of the frame 201, and the blade 202 is vertically slidably installed on the frame 201 through an elastic member 8 and is connected with the driving device 203.

[0032] It can be understood that when cutting the product, the driving device 203 can drive the blade 202 to move downward; and when the product cutting is completed, the blade 202 can move upward and reset under the elastic force of the elastic member 8, ready to start the next round of cutting task; this automatic reset design makes the reset of the blade 202 more convenient and quick, thereby improving production efficiency.

[0033] Specifically, a magnetic block 5 is installed at the top of the blade 202, and the driving device 203 includes an electromagnet. It should be known that when cutting a product, the electromagnet will be energized, and the electromagnet and the magnetic block 5 after being energized have the same poles. According to the principle that magnetic poles of the same polarity repel each other, the blade 202 can be driven to move downward to cut the product. When the product is cut, the electromagnet is de-energized, and the blade 202 can move upward and reset under the action of elastic force.

[0034] It should be noted that the conventional driving device 203 generally uses a hydraulic cylinder or a pneumatic cylinder to drive the blade 202 to move downward, but this method will have a certain driving reaction time during the process of retracting the blade 202, that is, the reset rate of the blade 202 is slow. In the present application, the product to be cut is a mixed silicone rubber with a relatively low hardness, and thus a large driving force is not required when the blade 202 moves downward. Therefore, in the present application, the blade 202 is driven downward by the action of magnetic force, and then the blade 202 is driven upward and reset by the action of elastic force. This avoids the pipeline setting of the conventional hydraulic cylinder or pneumatic cylinder, making the structure more concise, and also can make the reset reaction of the blade 202 more rapid, thereby improving production efficiency.

[0035] In this embodiment, Figure 3 As shown, the blade 202 slides in the following manner: a slide rail 7 is provided on the inner side of the frame 201, and a slider 6 is installed on the side of the blade 202. The slide rail 7 and the slider 6 form a sliding fit, thereby realizing the sliding installation of the blade 202 on the frame 201. Of course, the slide rail 7 and the slider 6 are preferably provided in a pair, that is, the slide rail 7 is provided inside the two sides of the frame 201, and the slider 6 is installed at the outer position on the two sides of the blade 202, so that the sliding stability of the blade 202 can be improved.

[0036] Based on the above embodiments, another implementation of the present application is as follows: Figure 3 As shown, the elastic member 8 has various structural forms, including but not limited to the following two:

[0037] Structure 1: The elastic member 8 is a spring, and both ends of the spring are connected to the slider 6 and the top end of the slide rail 7 respectively.

[0038] Structure 2: The elastic member 8 is an elastic rope (rubber rope or elastic rope), and the two ends of the elastic rope are connected to the slider 6 and the top of the slide rail 7 respectively.

[0039] It should be noted that both structures can meet actual needs, and technicians in this field can make a choice based on actual conditions.

[0040] The working principle of the utility model is:

[0041] like Figure 4 As shown in FIG. 1 , it is a flow chart of the operation of the cutting device. First, according to the required block mass of the product, the required weight of the mixed silicone rubber product is input on the control panel (i.e. the pressure-sensitive device 401 switches to the corresponding resistance value), and the device is started to run. Figure 1 As shown by the arrow in , the conveyor belt rotates clockwise, so that the product is conveyed to the right. When the weight of the finished rubber compound at the detection position on the conveyor belt (i.e., the position where the pressure-sensitive device 401 is located) reaches the set range, the conveyor belt will stop running, and the electromagnet inside the driving device 203 will generate magnetism that repels the magnetic block 5 on the top of the blade 202 under the action of the current, so that the cutting blade 202 falls vertically to cut off the finished rubber compound. At this time, the staff can take away the cut product, and then the weight at this position is reset and the electromagnet loses the magnetism that repels the magnetic block 5 on the top of the blade 202. The blade 202 is retracted along the slide rail 7 under the action of the top elastic member 8 and is sucked back to the top. The subsequent finished silicone rubber compound continues to be conveyed along the conveyor belt. The above process is repeated in this way to achieve the automatic cutting of the product at a certain weight.

[0042] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
