Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of belt conveyer, especially relates to a transport belt mechanical interface riveting tool. BACKGROUND

[0002] The belt conveyer is also called rubber belt conveyer, and the traction force of the belt conveyer is transmitted through the friction force between the transmission roller and the rubber belt, so the rubber belt must be pulled tight by the tensioning device, so that the rubber belt has a certain initial tension at the separation position of the transmission roller. The rubber belt is both a traction mechanism and a bearing mechanism, and there is no relative movement between the load and the rubber belt, so the friction resistance between the rubber belt and the load during operation is eliminated. Increasing the tension (initial tension) is beneficial to improving the transmission capacity of the traction force. During operation of the rubber belt conveyer, the rubber belt will be elongated, which will cause the traction force to decrease, so the rubber belt is appropriately pulled tight by the tensioning device to improve the traction force.

[0003] During the production process, the rubber belt needs to be replaced every certain period, or the rubber belt needs to be treated in an emergency even if it is not the period. The most critical step in the replacement process is the connection at the interface, because the connection strength at the interface determines the quality of the rubber belt replacement and the service life of the rubber belt. At present, the rubber belt is connected by first gluing and then using rubber nails for reinforcement. However, there are problems in this method. When the rubber nails are used to reinforce the glued part, even skilled operators often have problems such as nail deviation. In order to ensure the connection strength, the nails have to be removed and re-nailed, which will undoubtedly affect the overall strength of the rubber belt and increase the workload of the connection process.

DETAILED DESCRIPTION

[0026] The technical solutions of the utility model will be described clearly and completely in combination with specific embodiments, and obviously, the described embodiments are some of the embodiments of the utility model, not all the embodiments.

[0027] In order to more clearly illustrate the specific embodiments of the utility model or the technical solutions in prior art, the specific embodiments needed to be used in the specific embodiments or prior art description will be simply introduced, and obviously, the specific embodiments in the following description are some of the embodiments of the utility model, and for those skilled in the art, other specific embodiments can also be obtained without creative labor.

[0028] The components of the embodiments of the utility model described and shown in the specific embodiments here can be arranged and designed in numerous different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the specific embodiments is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model.

[0029] See Figures 1-5This is a schematic diagram of an embodiment of a conveyor belt mechanical interface riveting fixture of the present invention. It includes a pressing plate 1, a perforated plate 2, and an anvil plate 3. The three plates are respectively provided with functional units corresponding to the longitudinal and transverse coordinate positions and positioning holes 17. The functional unit on the pressing plate 1 is a pressing pin 4, the functional unit on the perforated plate 2 is a hollow sleeve 5, and the functional unit on the anvil plate 3 is a recess 6 with a rounded bottom. The tape 7 to be joined is sandwiched between the perforated plate 2 and the anvil plate 3. A press 8 is provided on the pressing plate 1. Before pressing, a belt nail 9 is installed in each hollow sleeve 5. Under the pressure of the pressing pin 4, the head of the belt nail 9 bends in the recess 6 and is pressed back into the tape 7 to rivet the two layers of tape.

[0030] The coordinates are arranged in a rectangular dot matrix, including dense areas A on both sides of tape 7 and sparse areas B in the middle of tape 7. The dot spacing in dense area A is 35mm × 35mm, and the dot spacing in sparse area B is 50mm × 50mm. To ensure connection strength, at least three rows of belt studs 9 are set in dense area A.

[0031] The outer sides of the perforated plate 2 and the cutting board 3 are respectively provided with clamping ear plates 10. The clamping ear plates 10 have connecting holes, which are smooth holes or open slots 11, for better clamping of the tape 7.

[0032] In this embodiment, the specifications of the pressure pin 4 are φ5mm×50mm. The 5mm specification of the pressure pin 4 is a nominal size, and the actual diameter is reduced by 0.2mm. The specifications of the hollow sleeve 5 are: inner hole φ5, length 25mm, and the specifications of the belt stud 9 are φ3×20mm. The thickness of the pressing plate 1 is 15mm, the thickness of the perforated plate 2 is 15mm, and the thickness of the anvil plate 3 is 20mm. The diameter of the recess 6 is 6mm and the depth is 2mm.

[0033] Press 8 is a hydraulic press, and the conveyor belt 7 is riveted on the hydraulic press worktable 12. The pressing pressure of press 8 is 6-10MPa, and it is held for 3-10 seconds after pressing to ensure that the belt stud 9 is sufficiently deformed.

[0034] The specific operation steps of the embodiment are as follows:

[0035] 1) Place the cutting board 3 below the interface of the tape 7 and the perforated plate 2 above the interface of the tape;

[0036] 2) After aligning the cutting board 3 and the perforated board 2, insert positioning pins into the four positioning holes 17. The purpose is to make the recesses 6 on the cutting board 3 correspond one-to-one with the holes on the perforated board 2.

[0037] 3) Secure the clamping ear plates 10 of the anvil plate 3 and the perforated plate 2 with bolts to tighten the belt at the interface;

[0038] 4) Insert the belt nail 9 into the hollow sleeve 5 in the perforated plate 2;

[0039] 5) Place the pressing plate 1 over the perforated plate 2, and ensure that the pressing pins 4 on the pressing plate 1 correspond one-to-one with the hollow sleeves 5 on the perforated plate 2.

[0040] 6) Use a press (manual or electric) to press and compact the pressing plate 1, perforated plate 2, tape interface, and cutting board 3, so that the belt nail 9 is driven into the tape at the same time. When the tip of the belt nail 9 passes through the tape 7, because the length of the belt nail 9 is greater than the thickness of the tape 7 interface, the tip of the belt nail 9 will turn back after hitting the pit of the cutting board 3 and be driven into the tape 7 again from the bottom, so as to avoid the nail tip protruding and injuring people.

[0041] See Figure 6 This is a schematic diagram of the pressing state of the jack in this embodiment of the utility model. The press 8 is a jack. The jack and tooling are set in the C-shaped pressing frame 13. The bottom opening of the pressing frame 13 has a clamping plate 14 symmetrically arranged on the left and right sides of the opening. The clamping plate 14 is connected to the pressing frame 13 through the hinge 15. After the clamping plate 14 is flipped vertically upward, the tape 7 can enter through the bottom opening. The perforated plate 2 and the anvil plate 3 clamp the tape 7 and are connected through the clamping ear plate 10. The pressing plate 1 enters from the front or rear side of the pressing frame 13 and is then connected and positioned with the perforated plate 2 and the anvil plate 3.

[0042] The bottom of the clamping plate 14 is provided with a reinforcing rib 16. When the clamping plate 14 is flipped to the horizontal position, the reinforcing rib 16 is clamped on the clamping frame 13 to keep the clamping plate in a horizontal state. At this time, when the jack is started, the two clamping plates 14 lift the tooling until the belt nail 9 is pressed into the tape, and the jack is released.

[0043] This utility model mainly utilizes a device composed of three steel plates with a recess 6, a hollow sleeve 5, and a pressure pin 4 to achieve uniform and efficient fixing of the belt nail 9 at the tape interface, thereby improving tape replacement efficiency, increasing tape interface strength, reducing the workload of operators during tape connection, and avoiding the risk of accidental injury during operation.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
