[0028] The following is combined with Figure 1 - Figure 2 to describe the cam arm spring force adjustment mechanism 10 of the present utility model.
[0029] In view of the problems in the prior art that the cam arm of the case packing machine has inconvenient spring force adjustment and poor adjustment effect, in order to solve the above problems, the present utility model provides a cam arm spring force adjustment mechanism 10, including a bracket 1, an adjustment part 2 and a guide rail 3.
[0030] Please refer to Figure 1, the bracket 1 has a first mounting surface 11 extending in the vertical direction and a second mounting surface 12 extending in the horizontal direction. In this embodiment, the bracket 1 includes a horizontal plate and a vertical plate. The vertical plate is disposed on the horizontal plate, and two adjacent surfaces of the vertical plate constitute the first mounting surface 11 and the second mounting surface 12. The bracket 1 can also be formed by selecting the mounting plate in the case sealer. In this way, the original structure of the case sealer can be modified without adding new structures, which is more convenient and fast.
[0031] The adjusting part 2 includes a driving lead screw 21 and an adjusting slider 22 disposed on the first mounting surface 11. Both the driving lead screw 21 and the adjusting slider 22 extend in the vertical direction. The driving lead screw 21 is used to drive the adjusting slider 22 to slide along the first mounting surface 11; the guide rail 3 is disposed on the second mounting surface 12 and faces the adjusting slider 22, and the adjusting slider 22 is slidably connected to the guide rail 3; wherein, a fixing member 221 is further provided on the adjusting slider 22, and the fixing member 221 is used to fix one end of the spring. The other end of the spring is fixed to the cam arm, and the spring extends in the vertical direction to adjust the elastic force under the movement of the adjusting slider 22.
[0032] It should be noted that the cam arm spring elastic force adjusting mechanism 10 provided by the present utility model greatly simplifies the steps of adjusting the spring elastic force and improves the safety of adjusting the spring elastic force. The driving lead screw 21 can adjust the elastic force of the spring by pushing up or down the adjusting slider 22. The upper part of the adjusting slider 22 fixes the upper end of the spring through the fixing member 221. When the driving lead screw 21 is adjusted upward, the pulling force of the spring can be increased, and vice versa. By adjusting the elastic force of the spring, the folding requirements of box skins with different hardnesses can be quickly adapted.
[0033] In order to facilitate the fixing of the driving lead screw 21, a mounting seat is provided on the first mounting surface 11, and a screw thread is provided on the mounting seat. Referring to the attached drawings, both sides of the mounting seat are fixedly connected to the first mounting surface 11 by screws. A boss is formed in the middle of the mounting seat, and a screw thread is provided on the boss. The screw thread extends in the vertical direction, and the driving lead screw 21 is threadedly connected to the screw thread. There are various ways for the driving lead screw 21 to move. In an optional embodiment, the end of the driving lead screw 21 has an adjusting grip 211, and the user can hold the adjusting grip 211 by hand and manually drive the driving lead screw 21 to rotate to make the driving lead screw 21 rise or fall; in another optional embodiment, a driving motor is further provided at the end of the driving lead screw 21, and the driving motor is drivingly connected to the driving lead screw 21 for driving the driving lead screw 21 to rotate. In other optional embodiments, a driving cylinder or the like can also be selected to drive the adjusting slider 22 to lift. However, considering the actual structure of the case sealer, the lead screw in the traditional case sealer can be modified, so that no additional expenditure is required, and the original structure and space of the equipment can be fully utilized.
[0034] In the technical solution provided by the present utility model, the guide rail 3 mainly plays a role in fixing and adjusting the adjusting slider 22. Specifically, please refer to Figure 1 - Figure 2 , the guide rail 3 includes a base 31 and two clamping plates 32 spaced on the base 31. The two clamping plates 32 extend towards the adjusting slider 22. The adjusting slider 22 is arranged between the two clamping plates 32 and is slidably connected to each clamping plate 32. The two clamping plates 32 can play a semi-enclosing role on the adjusting slider 22 to prevent the adjusting slider 22 from falling off. Further, sliders are provided on both clamping plates 32, and the adjusting slider 22 is provided with sliding grooves on two side walls that are oppositely arranged in the vertical upward direction. The sliding grooves extend in the vertical direction, and the sliders are slidably connected to the corresponding sliding grooves. Through the arrangement of the sliders on the clamping plates 32 and the sliding grooves on the side walls of the adjusting slider 22, the stability of the movement of the adjusting slider 22 can be ensured. Further still, a sliding groove is provided on the first mounting surface 11, and the sliding groove extends in the vertical direction. A slider is provided on one side of the adjusting slider 22 close to the first mounting surface 11, and the slider is slidably connected to the sliding groove. In this way, through the cooperation of multiple groups of sliders and sliding grooves, the stability of the movement of the adjusting slider 22 can be significantly improved.
[0035] It should be noted that in the above embodiment, the guide rail 3 is fixed on the second mounting surface 12. Therefore, there are two cooperation methods between the driving lead screw 21 and the adjusting slider 22. One is that the driving lead screw 21 is in abutting connection with the end surface of the adjusting slider 22, and the other is that the driving lead screw 21 is connected to the adjusting slider 22. Either of the two methods can be selected, and the present utility model does not limit this.
[0036] Further, in order to improve the applicable environment of the above adjusting mechanism, a sliding groove extending in the horizontal direction is opened on the second mounting surface 12, and a slider is correspondingly provided on the base 31. The slider is slidably connected to the sliding groove so that the base 31 is slidably connected to the second mounting surface 12. In this embodiment, the guide rail 3 is slidably connected to the second mounting surface 12, so that the position of the guide rail 3 is adjustable. Thus, the installation position of the spring is also adjustable. Further, the installation position of the cam arm is also adjustable. In this way, cam arms of different specifications can be adapted, and the installation and positioning of the mechanism are more convenient. It should be noted that if the position of the base 31 is adjustable, the driving lead screw 21 and the adjusting slider 22 adopt an abutting cooperation method, and there is no need to provide a sliding groove or a slider on the first mounting surface 11 for sliding cooperation. Further still, in order to ensure the stability of the movement of the adjusting slider 22, the end of the clamping plate 32 is bent to form a retaining piece, and the retaining piece abuts against the side of the adjusting slider 22 away from the first mounting surface 11.
[0037] It should also be noted that in the technical solution provided by the present utility model, the fixing member 221 is set as a bolt and is directly connected to the spring. The fixing member 221 can also be set as a mounting plate extending in the horizontal direction, and a plurality of hooks are provided on the mounting plate. The hooks are used to connect different numbers of springs.
[0038] The present utility model also provides a case packing and sealing machine, which includes a cam arm spring elastic force adjusting mechanism 10. Since the main inventive point of the present utility model lies in the cam arm spring elastic force adjusting mechanism 10, the structure of the case packing and sealing machine will not be described in detail herein.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
