Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of point breaking devices, in particular to a point breaking device for a coiling machine with a heat sealing function. Background Art
[0002] After the plastic bag is produced, the bag body of the plastic bag is in an integrated state. In the prior art, a continuous roll bag making machine is used to perform point-breaking operations on the plastic bag at equal distances, so that the plastic bag is divided into multiple incompletely disconnected individuals, so that multiple small-volume plastic bags can be directly separated under the action of external force later.
[0003] The plastic bags are moved to the bottom of the point breaking knife through the conveying device installed on the continuous roll bag making machine. At this time, the point breaking knife moves downward under the control of the first cylinder, so that the point breaking knife performs point breaking operations between two adjacent groups of plastic bags. However, when the point breaking knife moves upward, it will drive the plastic bags to move together, causing the moving direction of the plastic bags to deviate, affecting the accuracy of the point breaking position of the plastic bags in the later stage.
[0004] The main reason for the above problems is that the movement of the plastic bags is only through the conveying device arranged on the continuous roll bag making machine, and there are no devices on both sides of the breaking knife to press and position the plastic bags. After the breaking knife breaks the plastic bag, due to the friction and adhesion between the breaking position of the plastic bag and the outer wall of the breaking knife, the plastic bag will move equally with the breaking knife, causing the position of the plastic bag to be deviated, thereby affecting the precise correspondence between other positions of the plastic bag and the breaking knife. To address the above problems, we propose a continuous roll machine breaking device with heat sealing function. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a point breaking device which solves the problem that when the point breaking knife moves upward, it will drive the plastic bag to move together, causing the moving direction of the plastic bag to shift and affecting the accuracy of the point breaking position of the plastic bag in the later stage.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The embodiment of the present application provides a point breaking device to solve the problem that when the point breaking knife moves upward, it will drive the plastic bag to move together, causing the movement direction of the plastic bag to shift and affecting the accuracy of the point breaking position of the plastic bag in the later stage, thereby achieving the suppression positioning of the plastic bag.
[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] The utility model embodiment discloses a point breaking device of a coiling machine with a heat sealing function.
[0029] According to the attached Figure 1-6As shown, it includes a knife holder 1 arranged on the continuous roll bag making machine, a point breaking knife 101 movably connected to the knife holder 1, and a first cylinder 103 arranged on the knife holder 1 for controlling the point breaking knife 101 to move up and down. The model of the continuous roll bag making machine is KI-PK30-1648720008. When it is in use, the plastic bag is moved to the bottom of the point breaking knife 101 through the conveying device arranged on the continuous roll bag making machine. At this time, the point breaking knife 101 moves downward under the control of the first cylinder 103, so that the point breaking knife 101 performs a point breaking operation between two adjacent groups of plastic bags, so that the two groups of plastic bags can be directly separated later. The plastic after point breaking continues to move to the winding device arranged at the top end face of the continuous roll bag making machine through the conveying device, so that the plastic after point breaking is wound up. For details, please refer to the existing rolled point breaking garbage bags, etc. The plastic bags are not specifically drawn in the accompanying drawings.
[0030] Pressure mechanisms are provided on both sides of the point-breaking knife 101. When the point-breaking knife 101 moves in a direction away from the plastic bag under the action of the first cylinder 103, the pressure mechanism can prevent the plastic bag from moving with the point-breaking knife 101, so as to stably limit the position of the plastic bag. The pressure mechanism includes a pressure roller 201, which is slidably connected to the side wall of the tool holder 1. Two groups of pressure rollers 201 are located on both sides of the point-breaking knife 101. A counterweight 203 is connected to one end of the two groups of pressure rollers 201, and one end of the counterweight 203 is slidably connected to the side wall of the tool holder 1. A bearing 202 is fixedly connected to the bottom end face of the counterweight 203. The outer wall of one end of the pressure roller 201 is fixedly connected to the inner wall of the bearing 202. Through the provided bearing 202, when the pressure roller 201 rotates, the counterweight 203 will not rotate therewith.
[0031] The two groups of linkage blocks 206 are respectively connected to the two sides of the point breaking knife 101, and the position of the pressure roller 201 is adjusted by the contact between the linkage block 206 and the counterweight block 203. A group of fixed seats 102 are fixedly connected to both sides of the point breaking knife 101, and the two groups of linkage blocks 206 are respectively fixedly connected to the two groups of fixed seats 102. When the outer walls of the point breaking knife 101 and the pressure roller 201 are in contact with the outer wall of the plastic bag, the relative position between them can be referred to in the attached Figure 2 and 5 , so that when the point-breaking knife 101 and the linkage block 206 set on one side of the point-breaking knife 101 move upward under the action of its first cylinder 103, the pressure roller 201 will not move upward immediately with it. When the linkage block 206 moves up a certain distance, the linkage block 206 will contact the counterweight block 203. At this time, the upward linkage block 206 will drive the counterweight block 203 and the pressure roller 201 to move upward, so that the conveying device continues to drive the plastic bag to move.
[0032] A slide groove 204 is provided on the side wall of the tool holder 1, and one end of the counterweight block 203 and the linkage block 206 are both limited to slide inside the slide groove 204. A limit rod 205 is fixedly connected inside the slide groove 204, and the limit rod 205 is used to limit the moving path of the counterweight block 203 and the linkage block 206.
[0033] A fixing frame 3 is provided at the top end face of the continuous roll bag making machine, and an electric heating plate 301 for heat-sealing the plastic bag opening is provided inside the fixing frame 3. A second cylinder 302 for controlling the upward and downward movement of the electric heating plate 301 is provided at the inner top of the fixing frame 3.
[0034] The point breaking device of the continuous roll machine with heat sealing function is equipped with pressure mechanisms controlled by the point breaking knife 101 on both sides, so that when the point breaking knife 101 moves away from the plastic bag under the action of the first cylinder 103, the plastic bag can be prevented from moving together with the point breaking knife 101, and the position of the plastic bag is further pressed and positioned by the sequential upward movement of the point breaking knife 101 and the pressure roller, so as to avoid positional deviation during the point breaking process of the plastic bag.
[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
