Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a preheater bracket of a hose preheating station of a bag making machine. Background Art

[0002] The preheater bracket of the hose preheating station of the bag making machine is a component of the fully automatic bag making machine. In order to ensure the reliable heat sealing of the hose and the film and reduce the probability of micro leakage, the hose must be preheated by the preheater at the hose preheating station to ensure that the film material and the hose are heat sealed at the optimal temperature.

[0003] The existing hose preheating die seam is often parallel to the workbench. When entering the bag-making station, the hose die seam overlaps with the bag-making station die seam. Since the die seam of the bag-making station is subject to the smallest die extrusion force, the heat sealing effect is the worst, and it overlaps with the undesirable area of ​​the hose preheating, micro-leakage is very likely to occur at the junction of the film and the hose. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art to at least a certain extent. To this end, one purpose of the utility model is to propose a preheater bracket for a hose preheating station of a bag making machine, wherein after the heating block heats the hose, the moving transmission plate drives the transmission rod to move, and the hose is squeezed by the V-shaped transmission plate at the bottom of the transmission rod, and the hose is rotated by squeezing, so that after the mold seam of the hose enters the bag making station, it is staggered with the mold seam of the bag making station, and the undesirable area of ​​the hose preheating is located at the uniform force of the mold seam of the bag making station, so that the two bad points in the bag making station are compensated, the occurrence rate of micro leakage is reduced, and the production efficiency of the fully automatic bag making machine is improved.

[0005] The cam is provided with a support frame, and the support frame is provided with a support frame, and the support frame is provided with a support frame.

[0006] Preferably, the top end of each of the extrusion plates is fixedly connected with a rubber block, and an anti-slip groove is provided on the rubber block.

[0007] Preferably, two opposite sides of the two heating blocks are provided with symmetrically arranged arc grooves, and the arc grooves are arranged corresponding to the hoses.

[0008] Preferably, the screw rod is a bidirectional screw rod, and the screw rod is threadedly connected to the two transmission plates.

[0009] Preferably, the spring is designed as an arc-shaped structure and is a tension spring.

[0010] The beneficial effects of the utility model are as follows: after the heating block heats the hose, the driving rod is driven to move by the moving driving plate, and the hose is squeezed by the driving plate in a V-shape at the bottom end of the driving rod, and the hose is rotated by squeezing, so that after the mold seam of the hose enters the bag-making station, it is staggered with the mold seam of the bag-making station, and the undesirable preheating area of ​​the hose is located at the uniformly stressed part of the mold of the bag-making station, so that two bad points in the bag-making station are compensated, the occurrence rate of micro-leakage is reduced, and the production efficiency of the full-automatic bag-making machine is improved.

DETAILED DESCRIPTION

[0016] Reference Figure 1-4The preheater bracket of the hose preheating station of the bag making machine includes a workbench 1, a conveying roller 2 is fixedly installed on one side of the top of the workbench 1, a base 3 is fixedly installed on the side of the workbench 1 close to the conveying roller 2, a baffle bracket 4 is fixedly connected to one side of the base 3, a top plate 5 is fixedly connected to one side of the top of the baffle bracket 4, a symmetrically arranged guide rod 6 is fixedly connected to the top of the base 3, a symmetrically arranged transmission plate 7 is slidably connected to the guide rod 6, a motor 8 is fixedly installed on one side of the bottom end of the top plate 5, a screw rod 9 is fixedly connected to the output end of the motor 8, and the opposite side of the transmission plate 7 is fixed A heater 10 is connected, and a heating block 11 is fixedly connected to one side of the two heaters 10. A transmission block 12 is fixedly connected to one side of the transmission plate 7, and a transmission rod 13 is fixedly connected to the bottom end of the transmission block 12. Transmission grooves 14 are opened on both sides of the bottom end of the transmission rod 13. A transmission shaft 15 is rotatably connected in the transmission groove 14, and an extrusion plate 16 is fixedly connected to the transmission shaft 15. A symmetrically arranged spring 17 is fixedly connected to the side of the extrusion plate 16 close to the transmission groove 14, and the end of the spring 17 away from the extrusion plate 16 is fixedly connected to the transmission groove 14.

[0017] The top of the extrusion plate 16 is fixedly connected to a rubber block 18, and the rubber block 18 is provided with an anti-slip groove to increase the friction on the hose and reduce wear. The two heating blocks 11 are provided with symmetrically arranged arc grooves on the opposite sides, and the arc grooves are arranged corresponding to the hoses to facilitate preheating of the hoses. The screw rod 9 is a bidirectional screw rod, and the screw rod 9 is threadedly connected to the two transmission plates 7 to facilitate the screw rod 9 to transmit the transmission plates 7. The spring 17 is designed with an arc structure, and the spring 17 is a tension spring to facilitate the contraction of the spring 17.

[0018] When the device is used, when the motor 8 drives the transmission plate 7 to move toward each other through the screw rod 9, the transmission plate 7 drives the transmission block 12 to move, the transmission block 12 drives the transmission rod 13 to move, and the transmission rod 13 drives the extrusion plate 16 at the bottom through the transmission shaft 15 to squeeze the gap between the two hoses. When the two heating blocks 11 are fitted with each other, the extrusion plate 16 moves to the bottom end of the hose. After the heating of the heating block 11 is completed, the transmission plate 7 located at the top of the hose moves upward, and the V-shaped extrusion plate 16 squeezes the hose. The two squeezed hoses rotate in opposite directions. At this time, the mold seam of the hose is no longer parallel to the workbench 1. After the mold seam of the hose enters the bag-making station, it is staggered with the mold seam of the bag-making station, so that the hose at the mold seam of the bag-making station has a good preheating temperature. The unsatisfactory preheating area of ​​the hose is located at the uniform force of the mold of the bag-making station, so that the two bad points in the bag-making station are compensated, which greatly reduces the incidence of micro-leakage and improves the production efficiency of the automatic bag-making machine.
