Description

Technical Field

[0001] The utility model relates to oral liquid production equipment, in particular to a waste bag fixing device of a PVC filling line for oral liquid production. Background Art

[0002] In the production process of oral liquid, oral liquid can be filled in glass bottles or PVC bottles. On the PVC filling production line, PVC must first be hot-printed and then filled. During the hot-printing process, it needs to be cut, and the cut waste needs to be bagged for subsequent treatment.

[0003] Since the waste cut each time is in the shape of long strips, about 0.5 meters, when the waste is initially received, the waste cutting portion is at a certain height from the bottom of the waste bag. When the waste falls, it is scattered all over the place, resulting in insufficient filling in the bag. In addition, there is no structure for opening and fixing the bag. The existing method is to manually wrap it with wire, and the waste bag is perforated and inserted into the wire for fixing. Nearby workers are easily scratched by the wire. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a waste bag fixing device for a PVC filling line used in oral liquid production, which is convenient for fixing the waste bag and ensures sufficient filling.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A waste bag fixing device for a PVC filling line for oral liquid production comprises a frame, which is fixed at the lower part of a PVC cutting mechanism, a supporting rod is arranged perpendicularly to the length direction of the waste in the frame, a pair of connecting rods are arranged at the upper end of the supporting rods in parallel to the length direction of the waste, and the pair of connecting rods are driven by a driving mechanism to move relatively close or far away; a row of cutting knives for cutting are fixed on each connecting rod, and when the two connecting rods are relatively close, the cutting knives of the two connecting rods shear the waste; squeezing rollers are rotatably installed on the outer side around the lower end of the frame, and the side walls of the squeezing rollers are cut to form a plane, and a gap is maintained when the plane is parallel to the outer wall of the frame.

[0007] The driving mechanism includes two screw rods rotatably installed in the frame, and the two ends of each screw rod are respectively threadedly connected to one end of a paired connecting rod; and the left and right sections of each screw rod have opposite thread rotation directions; the two screw rods are driven by a synchronous belt transmission mechanism and a servo motor located outside the frame.

[0008] The outer wall of the squeezing roller is provided with an elastic rubber sleeve or a plurality of elastic rubber rings are adhered thereto at intervals.

[0009] The utility model provides a waste bag fixing device for a PVC filling line for oral liquid production, which has the following technical effects:

[0010] 1) By using a frame with a support rod, the waste can fall on the support rod in an orderly manner and be cut into small pieces by a cutter. In this way, after falling into the waste bag, it is more overlapped and the loading is more complete; at the same time, it is also conducive to the subsequent recycling of the waste.

[0011] 2) By using a squeezing roller, the waste bag can be quickly fixed to avoid scratches caused by the existing iron wire, which is safe and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-4As shown, a waste bag fixing device for a PVC filling line for oral liquid production includes a frame 1, which is a mouth-shaped structure, and is slightly smaller than the upper opening of a bag body 8, so that the bag body 8 can be conveniently sleeved on the outer wall of the frame 1. The frame 1 is fixed on the equipment housing at the lower part of the PVC cutting mechanism, and a support rod 2 is provided in the frame 1 perpendicular to the length direction of the waste. Since the distance between the support rod 2 and the PVC cutting mechanism is much smaller than that in the bag body 8 that originally fell to the ground, the cut waste 9 (long strips of PVC sheets) fall on the support rod 2 one after another, and the direction is roughly perpendicular to the support rod 2. A pair of connecting rods 3 are provided at the upper end of the support rod 2 in parallel with the length direction of the waste, and each connecting rod 3 is provided with a threaded hole at both ends along the axis direction of the support rod 2, and the threaded holes of the two connecting rods 3 are rotated in opposite directions. A screw rod 5.1 is rotatably installed at the appropriate positions on the left and right ends of the corresponding frame 1 through a bearing, and the thread on the screw rod 5.1 is divided into left and right sections and rotated in opposite directions. The two connecting rods 3 are threadedly connected with the corresponding threaded sections on the screw rod 5.1. A synchronous pulley is coaxially connected to the screw rod 5.1 outside the frame 1. The synchronous pulleys on the two screw rods 5.1 are of the same size and are wound with a synchronous belt. The synchronous pulley + synchronous belt constitute a synchronous belt transmission mechanism 5.2, which is driven by a servo motor 5.3.

[0022] When the servo motor 5.3 is started, the two screw rods 5.1 rotate synchronously, and the screw rods 5.1 rotate, thereby driving the two connecting rods 3 to move. Since the threads on the two connecting rods 3 and the screw rods 5.1 rotate in opposite directions, the two connecting rods 3 will be relatively close to or relatively far away from each other.

[0023] In addition, a row of cutters 4 for cutting is fixed on the opposite side of each connecting rod 3. When the two connecting rods 3 are relatively close, the cutters 4 of the two connecting rods 3 are correspondingly combined to achieve the shearing of the waste. In this way, the waste is cut into small pieces and falls into the bag body 8 below, so that the bag body 8 is filled more tightly and fully, and it is convenient for the later waste treatment.

[0024] like Figure 3 As shown, in addition, in order to achieve rapid fixation of the bag body 8 and avoid the traditional wire piercing the hand. The present application is provided with a certain length of squeezing roller 6 on the outer side of the lower part of the frame 1. The two ends of the squeezing roller 6 are rotatably mounted on the vertical part of the L-shaped frame, and the horizontal part of the L-shaped frame is welded upward on the side wall of the frame 1. The side wall of the squeezing roller 6 is cut to form a plane 7. When the plane 7 is parallel to the frame 1, a gap can be formed for the bag body 8 to pass through. The squeezing roller 6 is provided with a rotating handle on the outer side of the L-shaped frame.

[0025] like Figure 5-7 As shown, when the bag body 8 is sleeved on the lower outer wall of the frame 1, the squeezing roller 6 is rotated clockwise to the right, and the arc-shaped side wall of the squeezing roller 6 squeezes the bag body 8 and presses the bag body 8 against the outer wall of the frame 1. When the bag body 8 has a tendency to move downward, the squeezing roller 6 will also have a tendency to rotate clockwise, and can be further pressed, so that self-locking can be achieved.

[0026] In order to increase the pressing area, the outer wall of the squeezing roller 6 is provided with an elastic rubber sleeve or a plurality of elastic rubber rings are adhered at intervals. The elastic rubber sleeve or the elastic rubber ring has a certain degree of deformability, which can increase the pressing area, thereby increasing the friction resistance and realizing the reliability of the bag body 8 fixing.
