DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] Example 1
[0023] like Figure 1-Figure 4 As shown, an adjustable device for preventing a drag chain from opening is installed on a box stripper, comprising a first rail groove 2 installed on a fixing seat 1 of an auxiliary wing cylinder in the box stripper, a second rail groove 4 installed on a lower fixing plate 3 of a main wing cylinder in the box stripper, and a guide plate 5 installed on a fixing base of a main wing cylinder in the box stripper, wherein the guide plate is located on one side of the second rail groove 4, and two drag chains 6 on the box stripper are installed in the first rail groove 2 and the second rail groove 4 respectively;
[0024] The first rail groove 2 and the second rail groove 4 are both installed vertically, and one side of the first rail groove 2 and the second rail groove 4 in the height direction is provided with an opening for inserting the drag chain 6;
[0025] Since both the main wing span cylinder and the auxiliary wing span cylinder can be raised and lowered, the first rail groove 2 and the second rail groove 4 alone cannot effectively limit the drag chain 6 whose lifting state can change. Therefore, locking devices for limiting the drag chain 6 are installed on the first rail groove 2 and the second rail groove 4. The locking devices are set to limit the drag chain 6 in the first rail groove 2 or the second rail groove 4 during the lifting process.
[0026] In this embodiment, the locking device includes a positioning hole 7 opened on the first rail groove 2 or the second rail groove 4. The number of the positioning holes 7 on the first rail groove 2 or the second rail groove 4 is at least two, and the number of the positioning holes 7 is an even number and corresponds to each other. When the number of the positioning holes 7 is four or more, the positioning holes 7 are opened in sequence along the height direction of the first rail groove 2 or the second rail groove 4, and positioning pins 8 are inserted into the two corresponding positioning holes 7. The opening of the first rail groove 2 or the second rail groove 4 is blocked by the insertion of the positioning pins 8, and the drag chain 6 is within the first rail groove 2 or the second rail groove 4 defined by the drag chain 6.
[0027] The main wing cylinder lower fixing plate 3 and the auxiliary wing cylinder fixing seat 1 are arranged in a stepped manner from top to bottom, and the first rail groove 2 and the second rail groove 4 are staggered and installed on the main wing cylinder lower fixing plate 3 and the upper end of the auxiliary wing cylinder fixing seat 1 respectively. The staggered arrangement of the first rail groove 2 and the second rail groove 4 can avoid affecting the shape change of the drag chain 6 caused by lifting and lowering, and can facilitate the installation of the drag chain 6;
[0028] The guide plate 5 includes a vertical plate, a first inclined baffle plate fixed on the upper end of the vertical plate, and a second inclined baffle plate fixed on the lower end of the vertical plate. The vertical plate is fixed on one side of the main wing cylinder fixing seat close to the second rail groove 4. The upper end of the first inclined baffle plate and the lower end of the second inclined baffle plate are both inclined toward the side of the vertical plate close to the main wing cylinder fixing base. The setting of the guide plate 5 can provide a certain guiding effect when the drag chain 6 is raised or lowered, thereby preventing the drag chain 6 from colliding and shifting due to mechanical vibration, thereby causing the equipment to stop.
[0029] In combination with the above, the present application first limits the vertical direction of the drag chain 6 on the box stripper through the setting of the first rail groove 2 and the second rail groove 4, and then guides the possible deviation of the drag chain 6 during the lifting and lowering process through the setting of the guide plate 5, so as to avoid mechanical vibration during the operation of the box stripper and cause the drag chain 6 to be hit, so that the drag chain 6 can smoothly change its shape during the operation of the box stripper, and effectively solves the problem of position deviation and damage caused by vibration of the drag chain 6 in the current box stripper.
[0030] Example 2
[0031] like Figure 5 As shown, the structure of this embodiment is substantially the same as that of the embodiment 1. The difference between this embodiment and the embodiment 1 is that in this embodiment, the locking device includes a limit rod 9 and a torsion spring 10. The limit rod 9 is rotatably connected to the inner side wall of the first rail groove 2 or the second rail groove 4 through the torsion spring 10. The rotation direction of the limit rod 9 is upward or downward. The limit rod 9 is located at the side opening of the first rail groove 2 or the second rail groove 4.
[0032] In the present embodiment, there can be multiple locking devices, and due to the torsion spring 10, the locking device can limit more positions of the drag chain 6 without affecting the entry and exit of the drag chain 6 into the first rail groove 2 or the second rail groove 4. Compared with embodiment 1, the present embodiment can limit the drag chain 6 at more positions, thereby reducing the influence of mechanical vibration on the drag chain 6, and solving the problem of position displacement and damage caused by vibration of the drag chain 6 in the current box stripping machine.
[0033] Example 3
[0034] like Figure 6As shown, the structure of this embodiment is substantially the same as that of embodiment 1. The difference between this embodiment and embodiment 1 is that, in this embodiment, locking devices are installed on the lower fixing plate 3 of the main wing cylinder and the fixing seat 1 of the auxiliary wing cylinder. The two locking devices are installed corresponding to the first rail groove 2 and the second rail groove 4 respectively. The locking device includes a bottom tube 11, a spring 12 installed in the bottom tube 11, and an abutment rod 13 slidably connected in the bottom tube 11. The bottom end of the abutment rod 13 abuts against the spring 12, and the upper end of the abutment rod 13 is installed with a roller 14 abutting against the side of the drag chain 6. The bottom tube 11 is parallel to the first rail groove 2 or the second rail groove 4, and the bottom ends of the two locking devices are fixed to the lower fixing plate 3 of the main wing cylinder and the upper end of the fixing seat 1 of the auxiliary wing cylinder respectively.
[0035] By installing the locking device in this embodiment, the box stripper can always be in close contact with the drag chain 6 during the lifting operation, which can limit the position and deformation change trajectory of the drag chain 6 to a certain extent. It can also effectively solve the problem of position displacement and damage caused by vibration of the drag chain 6 in the current box stripper.
[0036] At present, the technical solution of this application has been put into pilot production, that is, a small-scale experiment before the large-scale mass production of the product; after the pilot production was completed, a user usage survey was conducted in a small range, and the survey results showed that user satisfaction was high; now we have begun to prepare for the formal production of the product for industrialization (including intellectual property risk warning survey).
