Description

Technical Field

[0001] The present application relates to the technical field of slider bag production, and in particular to a shearing device for slider bag production. Background Art

[0002] Slider bag, also known as slider zipper food bag, is a packaging bag made of polyethylene resin as the main raw material. The bag body, zipper and slider are made by film blowing, extrusion, injection molding and thermal bonding. This bag is widely used in daily life due to its convenient and practical design. It is mainly used for the preservation and storage of vegetables, fruits, grains, cooked food, etc. In the production process, a whole piece of film is cut into several small pieces by shearing to facilitate the production of slider bags.

[0003] Application No. 202021294488.0 discloses a cutting device for a food bag production line, including a workbench, a conveyor belt, a groove, a cutting device and a movable telescopic rod, etc. The specific working states of the shape converter, the cutter and the telescopic instrument are controlled by a CPU controller, and the control is also related to the shape and size information of the food bag, so that the actual operation can be specifically determined according to the actual situation. Therefore, the cutting device for the food bag production line of the utility model is not only simple in structure and easy to operate, but also can perform specific cutting according to the actual situation.

[0004] However, in use, there are the following defects:

[0005] Since there is no limiting and fixing facility for the food bags passing through the conveyor belt when cutting them, the cutting device may cause the food bags on the conveyor belt to shift due to air flow during the up and down movement of the cutting device, thereby causing the cutting to be skewed and affecting the production quality of the food bags. Utility Model Content

[0006] The purpose of the present application is to provide a shearing device for producing slider bags, which solves the problem raised in the background art that, due to the lack of limiting and fixing facilities for the food bags passing through the conveyor belt when cutting the food bags, the cutting device may cause the food bags on the conveyor belt to shift due to the air flow during the up and down movement of the cutting device, thereby causing the cutting to be skewed, affecting the production quality of the food bags.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a shearing device for slider bag production, comprising a base, a conveyor belt, a support frame and a cutting table, a transmission groove is horizontally opened in the center of the top end of the base, and a ventilation groove is horizontally opened in the bottom of the base, two transmission rods are fixedly installed between the left and right inner walls on both sides of the transmission groove, and the surface of the transmission rod is transmission-connected with the conveyor belt, a cutting table is fixedly installed in the center of the transmission groove, support frames are fixedly installed on the top surface of the base on both sides of the cutting table, a distribution box is fixedly installed above the top of the support frame, an electric push rod is fixedly installed on the lower side of the support frame below the distribution box, the bottom of the electric push rod is fixedly connected to a support plate, and a cutting blade is fixedly installed in the bottom center of the support plate.

[0008] In this technical solution, after the driving motor is energized, it drives the transmission rod to rotate, so that the conveyor belt moves and drives the slider bag to pass under the support frame. After being energized, the electric push rod extends downward, driving the support plate and the cutting blade to move downward, thereby completing the shearing of the slider bag below. The slider bag can be limited by the slide groove, slider, baffle, shock absorber and pressure plate. When the cutting blade is cutting, the pressure plates on both sides first contact the slider bag and press it. During the continued descent, the shock absorber is squeezed until it gradually recovers during the rising process after the cutting is completed. The baffle will block and limit the slider bag on both sides of the conveyor belt, thereby avoiding deviation during the shearing process, improving the shearing stability and efficiency of the device. At the same time, the slider bag can be slightly adsorbed through the ventilation holes, rectangular grooves and exhaust fans. After the exhaust fan is started in the ventilation groove, it will be slightly exhausted downward. The air from the upper part moves downward through the ventilation holes and rectangular grooves on the transmission belt, thereby slightly adsorbing the slider bag on the surface of the conveyor belt, thereby further ensuring the stability during cutting and improving the practicality of the device.

[0009] As an optional solution of the technical solution of the present application, a slide groove is provided at the top of the base on both sides of the conveyor belt, a slider is slidably connected to the inner side of the slide groove, a connecting block is fixedly welded to the top of the slider, and a baffle rod is fixedly connected to the connecting block on the side facing the conveyor belt.

[0010] As an optional solution of the technical solution of the present application, shock absorbers are fixedly installed at the bottom of the support plates on both sides of the cutting blade, and a pressure plate is fixedly connected to the bottom of the shock absorber.

[0011] As an optional solution of the technical solution of the present application, a plurality of ventilation holes are evenly opened on the surface of the conveyor belt.

[0012] As an optional solution of the technical solution of the present application, a rectangular groove is opened at the bottom of the transmission groove, the bottom of the rectangular groove is connected to the ventilation groove, and an exhaust fan is fixedly installed at the top of the ventilation groove below the rectangular groove.

[0013] As an optional solution of the technical solution of the present application, a driving motor is fixedly installed on the outer side wall of the base facing one end of the driving rod at both ends of the driving groove, and the rear end of the driving shaft of the driving motor is fixedly connected to the driving rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can limit the slider bag through the slide groove, slider, baffle, shock absorber and pressure plate. When the cutting blade is cutting, the pressure plates on both sides first contact the slider bag and press it. During the continued descent, the shock absorber is squeezed until the cutting is completed and then gradually recovers during the ascending process. The baffle will block and limit the two sides of the slider bag on both sides of the conveyor belt, thereby avoiding deviation during the shearing process and improving the shearing stability and efficiency of the device.

[0016] 2. The present application can slightly adsorb the slider bag through ventilation holes, rectangular grooves and exhaust fans. After the exhaust fan is started in the ventilation grooves, it will slightly exhaust air downwards. The air from above moves downwards through the ventilation holes and rectangular grooves on the transmission belt, thereby slightly adsorbing the slider bag on the surface of the conveyor belt, thereby further ensuring stability during cutting and improving the practicality of the device.

[0024] like Figure 1 and Figure 2 As shown, two transmission rods 4 are fixedly installed between the left and right inner walls on both sides of the transmission groove 2, and the surface of the transmission rod 4 is transmission-connected with a conveyor belt 5, and a plurality of ventilation holes 501 are evenly opened on the surface of the conveyor belt 5. A cutting table 18 is fixedly installed in the center of the transmission groove 2, and a support frame 12 is fixedly installed on the top surface of the base 1 on both sides of the cutting table 18, and a distribution box 13 is fixedly installed above the top of the support frame 12, and the cutting table 18 can withstand the extrusion of the cutting blade 17.

[0025] like Figure 1 As shown, a slide groove 8 is provided at the top of the base 1 on both sides of the conveyor belt 5, and a slider 9 is slidably connected to the inner side of the slide groove 8. A connecting block 10 is fixedly welded to the top of the slider 9, and a baffle rod 11 is fixedly connected to the side of the connecting block 10 facing the conveyor belt 5. The position of the baffle rod 11 can be freely adjusted to accommodate slider bags of different sizes.

[0026] like Figure 2 As shown, a rectangular groove 6 is provided at the bottom of the transmission groove 2, and the bottom of the rectangular groove 6 is connected to the ventilation groove 3. An exhaust fan 7 is fixedly installed at the top of the ventilation groove 3 below the rectangular groove 6, and the exhaust fan 7 has a small exhaust effect, so that the adsorption force is light, which facilitates the normal movement of the slider bag.

[0027] like Figure 2 As shown, an electric push rod 14 is fixedly installed on the lower side of the support frame 12 below the distribution box 13, and a support plate 15 is fixedly connected to the bottom of the electric push rod 14.
