Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a packaging box drying equipment. Background Technology

[0002] Packaging boxes are boxes used to package goods. They are usually made of materials such as cardboard, paper, plastic or metal. Drying packaging boxes is an important process step. Drying can make the packaging boxes stronger, better protect the products inside, ensure that the adhesives work best, and improve the overall structural stability.

[0003] In order to improve drying efficiency, traditional drying equipment is usually installed directly above the conveyor belt. The conveyor belt transports the packaging boxes from the inlet to the outlet. During the transport process, the packaging boxes pass by the dryer, where the dryer heats and dries the boxes.

[0004] However, when placing the packaging boxes onto the conveyor belt from the inlet, it is usually done manually. During the placement process, it is difficult for the manual placement to ensure that each packaging box is placed in the center of the conveyor belt. This can easily result in some packaging boxes being placed too far forward or too far back on the conveyor belt, which can lead to uneven drying, with one side of the packaging boxes being over-dried and the other side under-dried. Utility Model Content

[0005] The purpose of this invention is to provide a packaging box drying device to address the shortcomings and deficiencies of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a packaging box drying device, including a frame, a conveyor belt mounted on the frame, a dryer mounted on the frame above the conveyor belt, and further including two connecting seats mounted on the upper end face of the frame and symmetrically arranged front and back, two sliding rods respectively mounted on the two connecting seats, two guide blocks respectively mounted on the two sliding rods, an inlet arc surface respectively mounted on the two guide blocks, a plurality of sliding balls respectively mounted on the two guide blocks and the inlet arc surface, a plurality of ball grooves respectively opened on the two guide blocks and located outside each sliding ball for preventing the sliding balls from detaching from the guide blocks and for clearance fitting with the sliding balls, and a plurality of limiting protrusions equidistantly arranged on the upper end face of the conveyor belt, wherein the inlet arc surface on the guide block is located on the end face away from the dryer.

[0007] A further improvement is that: each of the two connecting seats is provided with a sliding through hole, and the two sliding rods are slidably disposed on the two connecting seats within the sliding through holes; and a fixing mechanism for fixing the sliding rods to the connecting seats is provided between the two connecting seats and the two sliding rods.

[0008] A further improvement is that the sliding rod is a square rod, the sliding hole is a square hole, and the upper end face of the sliding rod is provided with length scale lines.

[0009] A further improvement is that the fixing mechanism includes a threaded opening on the upper end face of the connecting seat and connected to the sliding through hole, and a fixing screw threaded to the connecting seat and located in the threaded opening.

[0010] A further improvement is that the upper end face of the fixing screw is provided with a rotating handle for easy hand control of the rotation of the fixing screw.

[0011] A further improvement is that the lower end face of the fixing screw is provided with an abutment block for increasing the friction between the fixing screw and the upper end face of the sliding rod when the lower end of the fixing screw abuts against the upper end face of the sliding rod.

[0012] A further improvement is that the abutment block is a conical block, and the abutment block is an elastic block.

[0013] A further improvement is that the surface of the conveyor belt is provided with a smooth layer.

[0014] A further improvement is that the smooth layer is a polytetrafluoroethylene coating.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the packaging box is manually placed onto the conveyor belt from the inlet end, the operator observes the position of the limiting protrusion and ensures that it is located to the right of the two guide blocks with sufficient distance between them to place a packaging box. The packaging box is then placed on the conveyor belt, with its side surface abutting against the limiting protrusion and positioned to the right between the two guide blocks. As the conveyor belt operates and the limiting protrusion restricts the packaging box, it is moved closer to the dryer. The two symmetrically arranged guide blocks are either close to or have a gap with the front and rear distance of the packaging box. When the packaging... When the box is placed in the center of the conveyor belt for transport, it can pass between two guide blocks for drying. Some boxes that are at the front or back of the conveyor belt will first contact the inlet arc surface of the guide block. At this time, the box is pushed by the limiting protrusion and moves towards the center of the conveyor belt through the sliding ball until it passes between the two guide blocks. This can straighten the boxes that are at the front or back of the conveyor belt to the center for transport, reducing the phenomenon of one side of the box being over-dried and the other side being under-dried after passing through the dryer, so that the box can be dried evenly.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figures 1 to 4As shown, the technical solution adopted in this specific embodiment is as follows: a packaging box drying device, including a frame 1, a conveyor belt 2 disposed on the frame 1, a dryer 3 disposed on the frame 1 above the conveyor belt, and two connecting seats 4 disposed on the upper end face of the frame 1 and symmetrically arranged front and back, two sliding rods 5 respectively disposed on the two connecting seats 4, two guide blocks 6 respectively disposed on the two sliding rods 5, an inlet arc surface 7 respectively disposed on the two guide blocks 6, a plurality of sliding balls 8 respectively disposed on the two guide blocks 6 and the inlet arc surface 7, a plurality of ball grooves 9 respectively formed on the two guide blocks 6 and located outside each sliding ball 8 to prevent the sliding balls 8 from detaching from the guide blocks 6 and to have clearance fit with the sliding balls 8, and a plurality of limiting protrusions 10 equidistantly disposed on the upper end face of the conveyor belt. The inlet arc surface 7 is located on the end face of the guide block 6 away from the dryer 3. The dryer 3 is located to the left of the two connecting seats. The dryer 3 is a traditional drying device for packaging boxes, typically fixed to the front and rear ends of the frame 1 by bolts using U-shaped seats. The dryer 3 usually includes resistance heating wires, temperature sensors, a fan hood, and a blower. The resistance heating wires are usually housed in the fan hood, and the blower forces air from the hood onto the conveyor belt 2. The blown air passes over the resistance heating wires, heating them and thus initiating the drying process. The temperature sensor monitors the heating temperature of the resistance wires. Since its structure is that of a traditional dryer 3 and is not a major improvement in this application, it will not be described in detail here. Two connecting seats 4 are fixed to the front and rear ends of the frame 1 by welding or bolts. The distance between the two guide blocks 6 is pre-adjusted according to the width of the packaging box. Ball grooves 9 are set along the outer surface of the guide blocks 6 and the inlet arc surface 7, with each sliding ball 8 positioned in each ball groove 9. The limiting protrusion 10 can be a rubber block with a height ranging from 5mm to 25mm, depending on the overall height of the packaging box. The limiting protrusion 10 is fixedly installed on the conveyor belt by adhesive or bolts.

[0024] In this embodiment, the sliding ball 8 can reduce the friction between the packaging box and the guide block 6 when the packaging box contacts the two guide blocks 6, making it easier for the packaging box to be conveyed between the two guide blocks 6.

[0025] Each of the two connecting seats 4 is provided with a sliding through hole 11, and the two sliding rods 5 are slidably disposed on the two connecting seats 4 and located in the sliding through hole 11. A fixing mechanism for fixing the sliding rods 5 to the connecting seats 4 is provided between the two connecting seats 4 and the two sliding rods 5.

[0026] In this embodiment, by setting the sliding perforation 11 and the sliding rod 5, the distance between the two guide blocks 6 can be adjusted by pushing and pulling the sliding rod 5, thereby adjusting the extension distance of the sliding rod 5 on the connecting seat 4, which can be adjusted according to the packaging box of different widths.

[0027] The sliding rod 5 is a square rod, the sliding through hole 11 is a square hole, and the upper end face of the sliding rod 5 is provided with a length scale line 12.

[0028] In this embodiment, the length scale line 12 allows the adjuster to observe the extended length when adjusting the distance between the two guide blocks 6, thereby ensuring that the two guide blocks 6 maintain the same extended distance and preventing the asymmetry of the two guide blocks 6 from affecting the positioning effect of the packaging box.

[0029] In this embodiment, the square rod and square hole prevent the sliding rod 5 from rotating in the sliding through hole 11, thereby allowing the length scale line 12 to remain on the upper surface of the sliding rod 5.

[0030] The fixing mechanism includes a threaded opening 13 on the upper end face of the connecting seat 4 and connected to the sliding through hole 11, and a fixing screw 14 threadedly connected to the connecting seat 4 and located in the threaded opening 13.

[0031] In this embodiment, the fixing screw 14 is turned forward by a tool to press against the upper end face of the sliding rod 5 located in the sliding through hole 11, thereby restricting the sliding of the sliding rod 5 in the sliding through hole 11 and achieving the effect of fixing the sliding rod 5. When it is necessary to release the fixation of the sliding rod 5 to adjust its extension length, the fixing screw 14 is turned in the opposite direction to remove it from pressing against the upper end face of the sliding rod 5, thereby releasing the fixation of the sliding rod 5.

[0032] The upper end face of the fixing screw 14 is provided with a rotating handle 15 for easy hand control of the rotation of the fixing screw 14.

[0033] The lower end face of the fixing screw 14 is provided with an abutment block 16 for increasing the friction between the fixing screw 14 and the upper end face of the sliding rod 5 when the lower end of the fixing screw 14 abuts against the upper end face of the sliding rod 5.

[0034] The abutment block 16 is a conical block, and the abutment block 16 is an elastic block. The abutment block 16 can be a rubber block or a silicone block.

[0035] In this embodiment, when the fixing screw 14 is tightened against the upper end face of the sliding rod 5, the elastic material abutment block 16 gradually undergoes elastic deformation under the pressure of the fixing screw 14, causing the abutment block 16 to generate a reaction force and press against the upper end face of the sliding rod 5. Since the abutment block 16 is a rubber block, when it elastically deforms and presses against the upper end face of the sliding rod 5, it can increase the friction between it and the sliding rod 5, and reduce the damage caused by the screw part of the fixing bolt pressing against the upper end face of the sliding rod 5 for a long time.

[0036] The surface of the conveyor belt 2 is provided with a smooth layer (not shown in the figure).

[0037] In this embodiment, the smooth layer (not shown in the figure) can reduce the friction between the conveyor belt 2 and the packaging box when the packaging box is placed on the conveyor belt 2, thereby making it easier for the packaging box to slide on the conveyor belt 2 and facilitating the adjustment of the packaging box's position.

[0038] The smooth layer (not shown in the figure) is a polytetrafluoroethylene coating.

[0039] The working principle of this utility model is as follows: When a packaging box is manually placed onto the conveyor belt 2 from the inlet end, the operator observes the position of the limiting protrusion 10, ensuring it is positioned to the right of the two guide blocks 6 with sufficient distance between them to place a packaging box. The packaging box is then placed on the conveyor belt, with its side surface abutting against the limiting protrusion 10 and positioned to the right between the two guide blocks 6. As the conveyor belt 2 operates and the limiting protrusion 10 restricts the packaging box, it is moved closer to the dryer 3. The two symmetrically arranged guide blocks 6 are either close to or have a gap with the front and rear distance of the packaging box. When the packaging box is placed... When conveyed at the center of the conveyor belt, the packaging boxes can pass between the two guide blocks 6 for drying. Some of the packaging boxes that are at the front or back of the conveyor belt will first contact the inlet arc surface 7 of the guide block 6. At this time, the packaging boxes are pushed by the limiting protrusion 10 and moved towards the center of the conveyor belt through the sliding ball 8 until the packaging boxes pass between the two guide blocks 6. This can straighten the packaging boxes that are at the front or back of the conveyor belt to the center position for conveying, reducing the phenomenon of one side of the packaging boxes being over-dried and the other side being under-dried after passing through the dryer 3, so that the packaging boxes can be dried evenly.
