Description

Technical Field

[0001] The utility model relates to the field of logistics packaging, in particular to a safety baffle structure and a paper pad machine. Background Art

[0002] A paper cushion machine is a device used to process flat paper materials into three-dimensional paper materials. It is often used to produce protective cushion materials and is widely used in the field of express logistics. A paper cushion machine generally includes a flat and tapered feed channel, with an inlet at the wider end and an outlet at the narrower end. The height of the narrower end is higher than the wider end, so that after the paper enters the channel, it is squeezed and deformed from a flat shape to a three-dimensional shape with a certain height; a clamping forming rubber wheel is provided at the outlet of the channel, which, on the one hand, pulls the paper for transportation, and on the other hand, clamps the three-dimensional paper for shaping, and finally produces cushion materials with a certain height.

[0003] However, since the entrance section of the paper pad machine's feeding channel is relatively wide, and the staff will pinch the two ends of the paper to feed the paper into the flow channel when loading, and due to the setting of the molding rubber wheel, the staff may over-reach during the process of feeding the paper, causing their hands to be clamped by the molding rubber wheel, posing a major safety hazard.

[0004] The countermeasure adopted by some existing paper padding machines is to make the entrance leave only a slit that can only insert flat paper. However, due to the wide variety of paper materials and various ways of feeding paper, such as rolled paper and rod-shaped paper, it is difficult to smoothly feed the paper through the slit. Other paper padding machines will bulge the position of the flow channel near the entrance into the flow channel to form a lower height channel to prevent hands from reaching in. However, the cost of making the bottom and top surfaces of the inner flow channel with bulges is high, which increases the cost of the equipment. And because the flow channel is gradually narrowed, the paper is compressed in the width direction, and its height direction will increase. The setting of the inner bulge reduces the height of the inner channel, so that in the process of inserting the paper, it will encounter resistance from the bulge, which is not convenient for feeding. Utility Model Content

[0005] The embodiments of the utility model provide a safety baffle structure and a paper pad machine to solve the above or other potential problems in the prior art.

[0006] According to one aspect of the utility model, a safety baffle structure is provided, including a baffle member and a mounting structure arranged on the baffle member for mounting to the upper or lower side of the entrance of the feed channel of the paper pad machine. The baffle member does not completely block the entrance of the feed channel to form a feeding gap for feeding.

[0007] The safety baffle structure of the utility model can be detachably installed at the entrance of the feed channel of the paper pad machine according to actual needs, thereby blocking part of the entrance of the feed channel to prevent the staff from reaching in, thereby improving the safety of the paper pad machine. At the same time, because the baffle member of the utility model does not completely block the entrance of the feed channel, and is only arranged at the entrance of the feed channel, the feed channel can leave a gap for feeding, and will not affect the inner channel size of the subsequent position of the entrance of the feed channel, thereby not affecting the feeding of the feed channel.

[0008] In some embodiments, the baffle member is disposed on an upper side of the inlet of the feed channel.

[0009] Thus, by such an arrangement, the feed gap can be formed at the lower side of the feed channel entrance. Since the fed paper generally sags under the action of gravity, the baffle member can be prevented from affecting the smoothness of the feed.

[0010] In some embodiments, the width of the feed gap is greater than 12 mm and no greater than 20 mm.

[0011] Therefore, by such an arrangement, it can be ensured that the size of the formed feeding gap can effectively block the insertion of the staff's hands, and it can also be ensured that the formed feeding gap can be fed smoothly.

[0012] In some embodiments, a side gap is left between at least one of the two sides of the baffle member and the inlet of the feed channel.

[0013] Therefore, by such an arrangement, it is possible to avoid the use of too large a piece of paper which causes the paper to contact and rub against both sides of the baffle member, thereby avoiding the situation in which the paper feeding is affected.

[0014] In some embodiments, the width of the side gap is greater than 20 mm and no greater than 30 mm.

[0015] Therefore, through such an arrangement, it can be ensured that the size of the formed side gap can effectively block the insertion of the staff's hands, and it can also be ensured that the formed side gap can be fed smoothly.

[0016] In some embodiments, a boss extending toward one side of the feed channel is disposed on the baffle member, and the mounting structure is disposed on the boss.

[0017] Thus, through such an arrangement, a structure connected to the inlet of the feed channel can be formed by the extended boss, thereby improving the stability of the connection between the baffle member and the inlet of the feed channel.

[0018] In some embodiments, the mounting structure includes an open slot disposed on the boss, a screw hole on the feed channel, and a screw.

[0019] Thus, by such an arrangement, the baffle member can be detachably mounted to the inlet of the feed channel through the structure of the screw hole, the screw and the open groove.

[0020] In some embodiments, a feeding hole is provided on the baffle member.

[0021] Therefore, through such an arrangement, the feed channel after the rear baffle member is installed can be further adapted to the feeding of more different types of materials.

[0022] In some embodiments, a viewing hole is provided on the baffle member.

[0023] Therefore, through such an arrangement, the staff can observe the specific feeding situation in the feeding channel behind the baffle member through the observation hole.

[0024] In some embodiments, at least two viewing holes are symmetrically arranged on the baffle member.

[0025] Therefore, by such an arrangement, the amount of light entering can be increased, making it easier for the staff to observe the specific feeding situation in the feeding channel behind the baffle member through the observation hole.

[0026] In some embodiments, a reinforcing rib structure is provided on one side surface of the baffle member facing the inlet of the feed channel.

[0027] Therefore, by such an arrangement, the structural strength of the baffle member itself can be enhanced.

[0028] In some embodiments, the baffle member is integrally formed of engineering plastic.

[0029] Therefore, by such an arrangement, the production efficiency of the product can be improved.

[0030] In some embodiments, the baffle member is shaped as an arc-shaped structure that curves toward the outside of the inlet of the feed channel.

[0031] Therefore, by such an arrangement, the probability of the baffle member being damaged by the tension and friction of the paper material can be reduced.

[0032] According to one aspect of the utility model, a paper padding machine is provided, comprising a paper padding machine body and the above-mentioned safety baffle structure, wherein the safety baffle structure is arranged at the entrance of the feeding channel of the paper padding machine body.

[0044] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0045] Embodiment 1

[0046] Figure 1 and Figure 5 The overall structure diagram of the safety baffle structure of an embodiment of the utility model is schematically shown. Figure 1 and Figure 5 As shown, the safety baffle structure of the utility model includes a baffle member 1 and a mounting structure arranged on the baffle member 1. The mounting structure is used to install the baffle member 1 to the upper side or lower side of the entrance of the feed channel of the paper pad machine, and to form a feed gap 71 for feeding between the baffle member 1 and the entrance of the feed channel of the paper pad machine. Specifically, when the baffle member 1 is installed to the upper side of the entrance of the feed channel, the formed feed gap 71 is located on the lower side of the entrance of the feed channel, and when the baffle member 1 is installed to the lower side of the entrance of the feed channel, the formed feed gap 71 is located on the upper side of the entrance of the feed channel. Refer to Figure 4 and Figure 5As shown, when the baffle member 1 is arranged at the entrance of the feed channel, it can be fixedly installed at the entrance of the feed channel, or it can be movably installed at the entrance of the feed channel. When the baffle member is movably installed at the entrance of the feed channel, the baffle member can be hingedly arranged at the entrance of the feed channel so that it can be flipped open to facilitate cleaning of the feed channel. When the baffle member is fixedly installed at the entrance of the feed channel, the baffle member can be vertically arranged at the entrance of the feed channel, or it can be arranged at a certain acute angle or obtuse angle with the feed channel, so that the baffle member 1 extends toward the outside or inside of the entrance of the feed channel, which can also play a corresponding technical effect. When the baffle member 1 is arranged to be vertically arranged at the entrance of the feed channel, the material used for the baffle member 1 can be reduced as much as possible, and the design cost can be reduced. Therefore, in the subsequent description, the structure of the baffle member 1 is mainly described in the design mode that the baffle member 1 is arranged to be vertically arranged at the entrance of the feed channel.

[0047] In some possible implementations, the formed feed gap 71 can be preferably set at the lower side of the entrance of the feed channel, that is, the baffle member 1 is installed at the upper side of the entrance of the feed channel. Since the fed material, such as paper, etc., will sag under the action of gravity, the feed gap 71 is set at the lower side of the entrance of the feed channel. This can prevent the material from contacting the safety baffle structure during feeding, thereby affecting the safety baffle structure, or causing tearing and pulling on the structure of the fed material, thereby ensuring the smoothness of the feeding and the quality of the feeding. As for the size of the feed gap 71, its width (i.e. Figure 5 The upper and lower height dimensions shown in the figure should be set to be greater than 12mm and not greater than 20mm. This can ensure that the size of the formed feeding gap 71 can effectively block the insertion of the staff's hands, and can also ensure that the formed feeding gap 71 can smoothly feed. Specifically, in this embodiment, the width of the feeding gap 71 is set to 20mm, which is a safe size required by the national standard, so that while solving the safety hazard of the staff's hands being pinched, it can also better ensure the smoothness of the feeding and not affect the feeding materials.

[0048] In some usage scenarios, when the paper pad machine is feeding, the width of the paper used may be larger than the width of the paper pad machine's feed channel. At this time, when the paper passes through the feed channel, the edges of the paper will bend and warp under the pressure of the two inner sides of the feed channel. In order to prevent the baffle member 1 set at the entrance of the feed channel from affecting the bent and warped part of the paper in this scenario, a side gap 72 needs to be left between at least one of the two sides of the baffle member 1 and the entrance of the feed channel. The reservation of the side gap 72 can effectively prevent the two side edges of the paper from contacting the baffle member 1 when they are bent and warped, thereby affecting the material quality, and avoiding affecting the baffle structure. Reference Figure 5 As shown, in some embodiments, the side gaps 72 can be provided on both sides of the baffle member 1, thereby minimizing the impact on the feeding material. Figure 5 The left and right width dimensions shown in the figure should be set to be greater than 20 mm and not greater than 30 mm. This can ensure that the size of the formed side gap 72 can effectively block the hand of the staff from reaching in, and can also ensure that the formed side gap 72 can smoothly feed the material. Specifically, in this embodiment, the width of the side gap 72 is set to 25 mm, so that the smoothness of the feeding can be ensured, the feeding material will not be affected, and safety considerations can be taken into account.

[0049] In order to better install the baffle member 1 at the entrance of the feed channel, since the baffle member 1 is arranged to be vertically arranged at the entrance of the feed channel, a boss 2 can be extended on the side of the baffle member 1 facing the feed channel, and the mounting structure is arranged on the boss 2, so that it can be connected and fixed to the top surface of the inner side of the entrance of the feed channel through the boss 2. At this time, the mounting structure may include an opening groove 3 arranged on the boss 2, a screw hole and a screw arranged on the top surface of the inner side of the entrance of the feed channel. For example, referring to Figures 1 to 3 As shown, the baffle member 1 can be detachably mounted at the entrance of the feed channel by passing a screw through the opening slot 3 on the boss 2 and threading it with the screw hole. For the mounting structure, in addition to the screw and screw hole structure described in this embodiment, different connection methods such as pins, buckles, and slide grooves can also be used for fixing, and the present invention does not limit this.

[0050] In some possible implementations, a feeding hole may be provided on the baffle member 1. The main function of the feeding hole is to reduce the impact of the baffle member 1 on the material when the material is a rolled paper. Since the rolled paper is in a rolled shape, it has a certain height, and thus it may be higher than the width of the formed feeding gap 71. Therefore, a feeding hole may be provided on the baffle member 1 to prevent the rolled paper from contacting and colliding with the baffle member 1 during feeding. Specifically, the shape of the feeding hole can be designed according to actual conditions. For example, it can be designed to be a round hole, an elliptical hole, a square hole, or the like. The utility model does not limit the shape of the feeding hole. For example, referring to Figure 1 and Figure 2 As shown, in Figure 1 and Figure 2In the embodiment shown, the feeding hole on the baffle member 1 is specifically arranged at the lower part of the baffle member 1, thereby effectively preventing the rolled paper from contacting the lower part of the baffle member 1 when passing through the feeding gap 71. The shape of the feeding hole is designed to be semi-elliptical, so as to increase the width of the feeding hole and further reduce the probability of the rolled paper contacting the baffle member 1 during feeding.

[0051] In some other possible implementations, the baffle member 1 may be further provided with an observation hole 5. The main function of the observation hole 5 is to enable the staff to observe the specific feeding conditions in the feeding channel behind the baffle member 1 through the baffle member 1, so as to be able to be informed in time when problems occur, and to provide timely feedback on the problems. Specifically, the observation hole 5 may be provided in the middle of the baffle member 1, and the number of the observation holes 5 may be adjusted according to the actual situation, such as one, or two symmetrically provided on the baffle member 1 with the center line of the baffle member 1 as a reference, and so on. The shape of the observation hole 5 may also be designed according to the actual situation, such as being able to be set as a round hole, a square hole, or a waist-shaped hole, etc. For example, referring to Figure 1 As shown, in Figure 1 In the embodiment shown, there are two observation holes 5, which are symmetrically arranged on the baffle member 1 along the center line of the baffle member 1, thereby further increasing the amount of light entering the feed channel through the observation holes 5, so that the staff can more easily observe the specific feeding situation in the feed channel behind the baffle member 1 through the observation holes 5.

[0052] The structure of the baffle member 1 itself can be made of one-piece engineering plastics, which can be more conducive to production. Specifically, the engineering plastics used can be ABS, PC, PP, PA, PC+ABS and other existing commonly used materials. In this embodiment, it is made of recyclable ABS material, which has low raw material cost, light weight, less pollution to the environment, and can ensure structural strength and appearance diversity. In order to improve the structural strength and structural stability of the baffle member 1 itself, in some possible implementations, a reinforcing rib structure 6 can also be provided on the baffle member 1 to strengthen the structure of the baffle member 1 itself through the reinforcing rib structure 6, and the shape of the baffle member 1 can also be designed to be an arc-shaped structure that bends toward the outside of the entrance of the feed channel. Among them, the baffle member 1 with an arc-shaped structure style that bends toward the outside of the entrance of the feed channel can form a structure style with a middle portion protruding toward the outside of the entrance of the feed channel, so that when the material contacts the baffle member 1 during feeding, it can slide along the arc-shaped structure around the baffle member 1, reducing the obstruction of the baffle member 1 to the material during feeding, thereby improving the structural stability of the baffle member 1. The reinforcing rib structure 6 provided on the baffle member 1 can be located on a side surface facing the inside of the entrance of the feed channel after the baffle member 1 is installed on the entrance of the feed channel, thereby not affecting the appearance of the baffle member 1 toward the outside, and not causing the reinforcing rib structure 6 to contact with the material entering the feed channel, which affects the smoothness of the feeding. For example, referring to Figure 2 and Figure 3 As shown, in Figure 2 and Figure 3 In the embodiment shown, the overall shape of the baffle member 1 is arc-shaped, and the reinforcing rib structure 6 is arranged on a side surface of the baffle member 1 facing the inner side of the entrance of the feed channel. The reinforcing rib structure 6 is a raised triangular structure, which connects the curved part of the baffle member 1 and the connecting part of the boss 2 and the baffle member 1, thereby improving the overall structural strength of the baffle member 1 itself.

[0053] The safety baffle structure of the utility model can be detachably installed at the entrance of the feed channel of the paper pad machine according to actual needs, thereby blocking part of the entrance of the feed channel to prevent the staff from reaching in, thereby improving the safety of the paper pad machine. At the same time, because the baffle member 1 of the utility model does not completely block the entrance of the feed channel, and is only arranged at the entrance of the feed channel, the feed channel can leave a gap for feeding, and will not affect the inner channel size of the subsequent position of the entrance of the feed channel, thereby not affecting the feeding of the feed channel.

Figure 4 and Figure 5 As shown, the paper pad machine of the utility model includes a paper pad machine body 7 and a safety baffle structure of any one embodiment described in the above embodiment one. A feeding channel for feeding is provided on the paper pad machine body 7. The safety baffle structure of any one embodiment described in the above embodiment one is arranged at the entrance of the feeding channel, thereby greatly improving the safety of the paper pad machine of the utility model and effectively reducing the probability of safety accidents.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
