Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and in particular relates to a food packaging tape feeding machine. Background Technology

[0002] In today's rapidly developing food industry, the efficiency and quality of food packaging directly impact a company's production benefits and product competitiveness. Currently, food packaging tape conveyor systems on the market have many shortcomings in operation.

[0003] Traditional packaging tape feeding machines are prone to tape slippage and deviation during traction, resulting in inaccurate tape length delivery, which affects the continuity of subsequent packaging processes and the appearance of the finished product. Furthermore, the design of the shearing mechanism is often inadequate, leading to uneven cuts and tape sticking, which not only reduces production efficiency but also wastes packaging tape material. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a food packaging tape feeding machine, which aims to solve the problem of unstable feeding of packaging tape in existing food packaging tape feeding machines.

[0005] The present invention adopts the following technical solution:

[0006] The food packaging tape feeding machine includes a frame, with unwinding wheels and a fixed frame at the top and bottom respectively. The fixed frame contains a pair of upper and lower traction wheels and a traction assembly for driving the upper traction wheel to rotate. A shearing mechanism is located below the traction wheel on the fixed frame. The fixed frame has a pair of left and right side blocks with guide grooves.

[0008] Furthermore, a guide plate is integrally formed above the shearing seat, and a bottom opening is formed below the shearing seat. The shearing blade is located inside the bottom opening, and the bottom of the shearing blade has a triangular structure.

[0009] Furthermore, each of the upper traction wheel shafts is equipped with a pulley, a traction motor is installed inside the fixed frame, a drive wheel is installed on the drive shaft of the traction motor, and a traction belt is fitted on the pulley and the drive wheel.

[0010] The beneficial effects of this utility model are:

[0011] 1. This device uses the combination of pressure rollers and tension springs on the pressure rod to achieve stable pressing of the packaging belt, prevent slippage and deviation, and improve conveying accuracy.

[0012] 2. The eccentric wheel-driven shearing blade structure makes the shearing action smoother, and the triangular structure of the shearing blade bottom design ensures neat cuts and avoids sticking.

[0020] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0022] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0023] Combination Figure 1-4As shown, the food packaging tape feeder includes a frame 1, with a unwinding wheel 2 and a fixed frame 3 respectively located at the top and bottom of the frame 1. The fixed frame 3 contains a pair of upper and lower traction wheels, with the upper traction wheel marked 41 and the lower traction wheel marked 42. The fixed frame 3 has a traction assembly for driving the upper traction wheel to rotate. A shearing mechanism is located below the traction wheel on the fixed frame 3. The fixed frame 3 has a pair of left and right side blocks 5, with guide grooves 6 on each side block. Pressure rods 7 pass through the two guide grooves 6. Retaining rings 8 are located within the two side blocks of the pressure rod 7. The pressure rod 7 is positioned close to the lower traction wheel 42. Several pressure rollers 9 are rotatably mounted on the pressure rod 7. Tension springs 10 are located at both ends of the pressure rod 9, with the other end of each tension spring 10 fixed to the side wall of the fixed frame 3.

[0024] Figure 3 In the design, the fixed frame 3 is equipped with a pair of left and right adjusting plates 11. The lower traction wheel 42 is rotatably mounted between the two adjusting plates 11. Each adjusting plate 11 has an oblong groove 12, through which an adjusting screw (not shown in the figure) passes. The adjusting screw is fixed to the fixed frame 3. The position of the lower traction wheel 42 can be finely adjusted. When a fine adjustment of the position of the lower traction wheel is required, simply loosen all the adjusting screws.

[0025] Before feeding the food packaging tape, adjust the position of the lower traction wheel to create a gap between the upper and lower traction wheels. The packaging tape is released from the unwinding wheel, passes through the gap between the upper and lower traction wheels, and then the pressure bar is pushed outward, creating a gap where the pressure wheel moves away from the lower traction wheel. The packaging tape then passes through this gap, and the pressure bar is released. Under the action of the tension spring, the pressure wheel presses the packaging tape tightly. Then, adjust the position of the lower traction wheel again to ensure the upper and lower traction wheels are pressed tightly against the packaging tape. Finally, pull the packaging tape to the downstream station.

[0026] During the feeding of food packaging straps, the upper traction wheel rotates, and with the cooperation of the lower traction wheel, the packaging straps are fed out. During feeding, multiple pressure rollers on the pressure bar work in conjunction with the lower traction wheel to achieve multi-point compression of the packaging straps. Combined with the elastic adjustment of the tension spring, this effectively prevents the packaging straps from slipping and deviating, improving the stability of the packaging straps during feeding.

[0027] Because the pressure rod can slide adaptively in the guide groove under the action of the tension spring, the pressure roller can adaptively press the packaging tape of different materials, thus improving the versatility of the device.

[0028] In addition, the pressure bar is equipped with retaining rings on both sides. The outer diameter of the retaining rings is larger than the width of the guide groove. The retaining rings can limit the pressure bar to the left and right, further improving the stability of the packaging tape during delivery.

[0029] As a preferred structure, such as Figure 2 , Figure 5-6The shearing mechanism includes a shearing seat 14, in which a shearing blade 15 is slidably disposed. A shearing assembly for driving the shearing blade 15 to slide up and down is provided on the fixed frame 3. The shearing assembly includes a rotating shaft 16, with a driven wheel 17 at one end and an eccentric wheel 18 at the other end. The eccentric position of the eccentric wheel 18 is rotatably connected to the shearing blade 15 through a short shaft 19. A shearing motor 20 is provided on the fixed frame 3. The drive shaft of the shearing motor 20 is provided with a driving wheel 21. A shearing belt (not shown in the figure) is sleeved between the driving wheel 21 and the driven wheel 22.

[0030] When it is necessary to cut the packaging tape, the traction assembly stops working, and the upper traction wheel no longer rotates. At that time, the cutting assembly drives the cutting blade to slide downwards, completing the cutting of the packaging tape. That is, the cutting motor starts working, driving the drive wheel to rotate, which in turn drives the driven wheel and the shaft to rotate through the cutting belt, thereby causing the eccentric wheel to rotate. The eccentric wheel drives the cutting blade to move downwards through the short shaft, realizing the cutting of the packaging tape.

[0031] In this structure, such as Figure 5 The shearing seat 14 has a guide plate 24 integrally formed on its upper part and a bottom opening on its lower part. The shearing blade 15 is located inside the bottom opening and has a triangular structure at its bottom.

[0032] The shearing seat is fixed to the front side of the fixing frame; a guide plate is integrally formed above the shearing seat, and the guide plate is inclined to guide the packaging tape. The shearing blade structure can improve the shearing efficiency and the flatness of the cut.

[0033] As a specific structure, such as Figure 3 The upper traction wheel's shaft is equipped with pulleys 26, the fixed frame contains a traction motor 27, the traction motor's drive shaft is equipped with a drive wheel 28, and the pulleys and drive wheel are both fitted with a traction belt 29.

[0034] In this device, the surface of the traction wheel is provided with anti-slip texture to increase friction with the packaging strap. The traction motor drives the pulley to rotate through the drive wheel and traction belt, and with the cooperation of the lower traction wheel, the packaging strap is fed out.

[0035] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
